Although most poisoning deaths are not preventable with current medical technology, in some cases different management decisions may have prevented fatal outcomes. This study aims to review reported poisoning-related deaths for preventability to provide insight to improve future care. Fatality abstracts published in the US National Poison Data System (NPDS) Annual Reports (2008-2012) were analyzed. Preventability was graded using a Likert scale of 1 (definitely non-preventable) to 6 (definitely preventable). Two medical toxicologists screened all cases. Cases deemed definitely not preventable (score 1) by both reviewers were excluded from further review and considered to be "non-preventable". All cases considered at least possibly preventable by either screener were reviewed by a multidisciplinary panel of 5 physicians for preventability scoring. Differences were resolved by consensus. Cases determined to be "preventable" (scores 4-6) were characterized by type of improvement issue involved (diagnosis, treatment, monitoring, other) and recurring scenarios. Of 390 published abstracts, 78 (20.0%) deaths were considered at least possibly preventable by at least one screener. Of these, 34 (8.7%) deaths were determined to be "preventable" by the panel. Inter-observer agreement by weighted kappa analysis was 0.58 for screening, 0.24 for preventability, and 0.44 for specific aspects of care. The most common toxicants were salicylates (n = 9), opioids (n = 4), toxic alcohols (n = 3), fluoride containing product (n = 3), and bupropion (n = 3). The most common improvement opportunities involved treatment and monitoring. Most of the ingested substances in preventable deaths have delayed GI absorption or require metabolic activation to produce a delayed effect (such as salicylates, opioids, and toxic alcohols), and therefore provide an opportunity for early recognition and successful interventions. Most improvement opportunities are clearly described in the literature but may be not recognized. Based on an analysis of published NPDS data, a considerable number of poisoning-related deaths reaching medical attention may be preventable. The most common scenarios involved in potentially preventable poisoning fatalities related to monitoring and treatment. Salicylates and opioids were the most common agents involved in preventable deaths.

Aims. The study aimed to present the experience of a screening programme for early detection of diabetic retinopathy (DR) using a nonmydriatic fundus camera, evaluating the feasibility in terms of validity, resources absorption, and future advantages of a potential application, in an Italian local health authority. Methods. Diabetic patients living in the town of Ponzano, Veneto Region (Northern Italy), were invited to be enrolled in the screening programme. The “no prevention strategy” with the inclusion of the estimation of blindness related costs was compared with screening costs in order to evaluate a future extensive and feasible implementation of the procedure, through a budget impact approach. Results. Out of 498 diabetic patients eligible, 80% was enrolled in the screening programme. 115 patients (34%) were referred to an ophthalmologist and 9 cases required prompt treatment for either proliferative DR or macular edema. Based on the pilot data, it emerged that an extensive use of the investigated screening programme, within the Greater Treviso area, could prevent 6 cases of blindness every year, resulting in a saving of €271,543.32 (−13.71%). Conclusions. Fundus images obtained with a nonmydriatic fundus camera could be considered an effective, cost-sparing, and feasible screening tool for the early detection of DR, preventing blindness as a result of diabetes.

Cancer is a major chronic disease threatening the people's health in China. We reviewed the latest advances on cancer surveillance, prevention and control in our country, which may provide important clues for future cancer control. We used data from the National Central Cancer Registry, to describe and analyze the latest cancer statistics in China. We summarized updated informations on cancer control policies, conducting network, as well as programs in the country. We provided important suggestions on the future strategies of cancer prevention and control. The overall cancer burden in China has been increasing during the past decades. In 2014, there were about 3 804 000 new cancer cases and 2 296 000 cancer deaths in China. The age-standardized cancer incidence and mortality rates were 190.63/100 000 and 106.98/100 000, respectively. China has formed a comprehensive network on cancer prevention and control. Nationwide population-based cancer surveillance has been built up. The population coverage of cancer surveillance has been expanded, and the data quality has been improved. As the aging population is increasing and unhealthy life styles persist in our country, there will be an unnegligible cancer burden in China. Based on the comprehensive rationale of cancer control and prevention, National Cancer Center of China will perform its duty for future precise cancer control and prevention, based on cancer surveillance statistics.

Case management services have been implemented in suicide prevention programs. To investigate whether case management is an effective strategy for reducing the risks of repeated suicide attempts and completed suicides in a city with high suicide rates in northern Taiwan. The Suicide Prevention Center of Keelung City (KSPC) was established in April 2005. Subjects included a consecutive sample of individuals (N = 2,496) registered in KSPC databases between January 1, 2006, and December 31, 2011, with at least one episode of nonfatal self-harm. Subjects were tracked for the duration of the study. Of all the subjects, 1,013 (40.6%) received case management services; 416 (16.7%) had at least one other deliberate self-harm episode and 52 (2.1%) eventually died by suicide. No significant differences were found in the risks of repeated self-harm and completed suicides between suicide survivors who received case management and those who refused the services. However, a significant reduction in suicide rates was found after KSPC was established. Findings suggest that case management services might not reduce the risks of suicide repetition among suicide survivors during long-term follow-up. Future investigation is warranted to determine factors impacting the downward trend of suicide rates.

Evidence-based intervention (EBI) de-adoption and its influence on public health organizations are largely unexplored within public health implementation research. However, a recent shift in support for HIV prevention EBIs by the Centers for Disease Control and Prevention provides an opportunity to explore EBI de-adoption. The current mixed-method study examines EBI de-adoption and the subsequent impact on a community-based organization (CBO) dedicated to HIV prevention. We conducted a case study with a CBO implementing RESPECT, an HIV prevention EBI, over 5 years (2010-2014), but then de-adopted the intervention. We collected archival data documenting RESPECT implementation and conducted two semi-structured interviews with RESPECT staff (N = 5). Using Fixsen and colleagues' implementation framework, we developed a narrative of RESPECT implementation, delivery, and de-adoption and a thematic analysis to understand additional consequences of RESPECT de-adoption. Discontinuation of RESPECT activities unfolded in a process over time, requiring effort by RESPECT staff. RESPECT de-adoption had wide-reaching influences on individual staff, interactions between the staff and the community, the agency overall, and for implementation of future EBIs. We propose a revision of the implementation framework, incorporating EBI de-adoption as a phase of the implementation cycle. Furthermore, EBI de-adoption may have important, unintended consequences and can inform future HIV prevention strategies and guide research focusing on EBI de-adoption.

Despite the recognized need for structural-level HIV prevention interventions that focus on economic empowerment to reduce women’s HIV risks, few science-based programs have focused on securing women’s land ownership as a primary or secondary HIV risk reduction strategy. The current study focused on a community-led land and property rights model that was implemented in two rural areas of western Kenya where HIV prevalence was high (24–30%) and property rights violations were common. The program was designed to reduce women’s HIV risk at the community level by protecting and enhancing women’s access to and ownership of land. Through in-depth interviews with 50 program leaders and implementers of this program we sought to identify the strategies that were used to prevent, mediate, and resolve property rights violations. Results included four strategies: (1) rights-based education of both women and men individually and at the community level, (2) funeral committees that intervene to prevent property grabbing and disinheritance, (3) paralegal training of traditional leaders and community members and local adjudication of cases of property rights violations, and (4) referring property rights violations to the formal justice system when these are not resolved at the community level. Study participants underscored that local mediation of cases resulted in a higher success rate than women experienced in the formal court system, underscoring the importance of community-level solutions to property rights violations. The current study assists researchers in understanding the steps needed to prevent and resolve women’s property rights violations so as to bolster the literature on potential structural HIV prevention interventions. Future research should rigorously test property rights programs as a structural HIV prevention intervention. PMID:24116828

2017-04-01

We introduce a new project "Translating weather extremes into the future - a case for Norway" (TWEX - http://www.cicero.uio.no/en/twex). In TWEX, we take a novel "Tales of future weather" approach in which we use future scenarios tailored to a specific region and stakeholder in order to gain a more realistic picture of what future weather extremes might look like in a particular context. We focus on hydroclimatic extremes associated with a particular circulation pattern (so-called "Atmospheric River") leading to heavy rainfall in fall and winter along the West Coast of Norway and causing high-impact floods in Norwegian communities. We translate selected past events into the future (e.g., 2090) by using an approach very similar to what is used today for weather prediction. The data generated in TWEX will be distributed by standard (weather prediction) communication channels of the Norwegian Meteorological Institute and thus, will be accessible by end-user in a well-known data format for analyzing the impact of the events in the future and support decision-making on hazard prevention and adaptation planning.

The purpose of the present study was to address 1) whether exercise provides protection against new-onset depression and anxiety and 2) if so, the intensity and amount of exercise required to gain protection and, lastly, 3) the mechanisms that underlie any association. A "healthy" cohort of 33,908 adults, selected on the basis of having no symptoms of common mental disorder or limiting physical health conditions, was prospectively followed for 11 years. Validated measures of exercise, depression, anxiety, and a range of potential confounding and mediating factors were collected. Undertaking regular leisure-time exercise was associated with reduced incidence of future depression but not anxiety. The majority of this protective effect occurred at low levels of exercise and was observed regardless of intensity. After adjustment for confounders, the population attributable fraction suggests that, assuming the relationship is causal, 12% of future cases of depression could have been prevented if all participants had engaged in at least 1 hour of physical activity each week. The social and physical health benefits of exercise explained a small proportion of the protective effect. Previously proposed biological mechanisms, such as alterations in parasympathetic vagal tone, did not appear to have a role in explaining the protection against depression. Regular leisure-time exercise of any intensity provides protection against future depression but not anxiety. Relatively modest changes in population levels of exercise may have important public mental health benefits and prevent a substantial number of new cases of depression.

Botulism is a severe neuroparalytic disease resulting from exposure to one of the most poisonous toxins to humans. Because of this high potency and the use of toxins as biological weapons, botulism is a public health concern and each case represents an emergency. Current therapy involves respiratory supportive care and anti-toxins administration. As a preventive measure, vaccination against toxins represents an effective strategy but is undesirable due the rarity of botulism and the effectiveness of toxins in treating several neuromuscular disorders. This paper summarizes the current issues in botulism treatment and prevention, highlighting the challenge for future researches.

Atrial Arrhythmias in Astronauts - Summary of a NASA Summit

NASA Technical Reports Server (NTRS)

Barr, Yael R.; Watkins, Sharmila D.; Polk, J. D.

2010-01-01

Background and Problem Definition: To evaluate NASA s current standards and practices related to atrial arrhythmias in astronauts, Space Medicine s Advanced Projects Section at the Johnson Space Center was tasked with organizing a summit to discuss the approach to atrial arrhythmias in the astronaut cohort. Since 1959, 11 cases of atrial fibrillation, atrial flutter, or supraventricular tachycardia have been recorded among active corps crewmembers. Most of the cases were paroxysmal, although a few were sustained. While most of the affected crewmembers were asymptomatic, those slated for long-duration space flight underwent radiofrequency ablation treatment to prevent further episodes of the arrhythmia. The summit was convened to solicit expert opinion on screening, diagnosis, and treatment options, to identify gaps in knowledge, and to propose relevant research initiatives. Summit Meeting Objectives: The Atrial Arrhythmia Summit brought together a panel of six cardiologists, including nationally and internationally renowned leaders in cardiac electrophysiology, exercise physiology, and space flight cardiovascular physiology. The primary objectives of the summit discussions were to evaluate cases of atrial arrhythmia in the astronaut population, to understand the factors that may predispose an individual to this condition, to understand NASA s current capabilities for screening, diagnosis, and treatment, to discuss the risks associated with treatment of crewmembers assigned to long-duration missions or extravehicular activities, and to discuss recommendations for prevention or management of future cases. Summary of Recommendations: The summit panel s recommendations were grouped into seven categories: Epidemiology, Screening, Standards and Selection, Treatment of Atrial Fibrillation Manifesting Preflight, Atrial Fibrillation during Flight, Prevention of Atrial Fibrillation, and Future Research

Past, present and future targets for immunotherapy in ovarian cancer

2015-01-01

Ovarian cancer is the leading cause of death from gynecologic malignancy in the US. Treatments have improved with conventional cytotoxic chemotherapy and advanced surgical techniques but disease recurrence is common and fatal in nearly all cases. Current evidence suggests that the immune system and its ability to recognize and eliminate microscopic disease is paramount in preventing recurrence. Ovarian cancer immunotherapy is targeting tumors through active, passive and adoptive approaches. The goal of immunotherapy is to balance the activation of the immune system against cancer while preventing the potential for tremendous toxicity elicited by immune modulation. In this paper we will review the different immunotherapies available for ovarian cancer as well as current ongoing studies and potential future directions. PMID:25524384

Among the known risk factors, smoking is clearly related to the incidence of lung cancer and alcohol consumption is to breast cancer. In this manuscript we modelled the potential benefits of reductions in smoking or alcohol prevalence for the burden of these cancers. We used Prevent v.3.01 to assess the changes in incidence as a result of risk factor changes. Incidence of lung and breast cancer until 2050 was predicted under two scenarios: ideal (total elimination of smoking and reduction of alcohol intake to maximum 1 units/d for women) and optimistic (decreasing prevalence of risk factors because of a 10% increase in cigarette and alcohol beverage price, repeated every 5 years). Danish data from the household surveys, cancer registration and Eurostat were used. Up to 49% less new lung cancer cases can be expected in 2050 if smoking were to be completely eliminated. Five-yearly 10% price increases may prevent 521 new lung cancer cases in 2050 (21% less cases). An intervention that immediately reduces population alcohol consumption to the recommended level (below 12 g/d) may lower breast cancer by 7%, preventing 445 out of the 6060 expected new cases in 2050. Five-yearly 10% price increases in alcoholic beverages achieved a reduction of half as expected by the ideal scenario, i.e. 4% (262) preventable cases in 2050. The future burden of lung and breast cancer could be markedly reduced by intervening in their risk factors. Prevent illustrates the benefit of interventions and may serve as guidance in political decision-making. Copyright © 2010 Elsevier Ltd. All rights reserved.

The relevance of unrelated costs internal and external to the healthcare sector to the outcome of a cost-comparison analysis of secondary prevention: the case of general colorectal cancer screening in the German population.

PubMed

Tscheulin, Dieter K; Drevs, Florian

2010-04-01

The potential of secondary prevention measures, such as cancer screening, to produce cost savings in the healthcare sector is a controversial issue in healthcare economics. Potential savings are calculated by comparing treatment costs with the cost of a prevention program. When survivors' subsequent unrelated health care costs are included in the calculation, however, the overall cost of disease prevention rises. What have not been studied to date are the secondary effects of fatal disease prevention measures on social security systems. From the perspective of a policy maker responsible for a social security system budget, it is not only future healthcare costs that are relevant for budgeting, but also changes in the contributions to, and expenditures from, statutory pension insurance and health insurance systems. An examination of the effect of longer life expectancies on these insurance systems can be justified by the fact that European social security systems are regulated by the state, and there is no clear separation between the financing of individual insurance systems due to cross-subsidisation. This paper looks at how the results of cost-comparison analyses vary depending on the inclusion or exclusion of future healthcare and non-healthcare costs, using the example of colorectal cancer screening in the German general population. In contrast to previous studies, not only are future unrelated medical costs considered, but also the effects on the social security system. If a German colorectal cancer screening program were implemented, and unrelated future medical care were excluded from the cost-benefit analysis, savings of up to 548 million euros per year would be expected. The screening program would, at the same time, generate costs in the healthcare sector as well as in the social security system of 2,037 million euros per year. Because the amount of future contributions and expenditures in the social security system depends on the age and gender of the recipients of the screening program (i.e. survivors of a typically fatal condition), the impact of age and gender on the results of a cost-comparison analysis of colorectal cancer screening are presented and discussed. Our study shows that colorectal cancer screening generates individual cost savings in the social security system up to a life expectancy of 60 years. Beyond that age, the balance between a recipient's social security contributions and insurance system expenditure is negative. The paper clarifies the relevance of healthcare costs not related to the prevented disease to the economic evaluation of prevention programs, particularly in the case of fatal diseases such as colorectal cancer. The results of the study imply that, from an economic perspective, the participation of at-risk individuals in disease prevention programs should be promoted.

Estimate of the global burden of cervical adenocarcinoma and potential impact of prophylactic human papillomavirus vaccination

PubMed Central

2013-01-01

Background Data on the current burden of adenocarcinoma (ADC) and histology-specific human papillomavirus (HPV) type distribution are relevant to predict the future impact of prophylactic HPV vaccines. Methods We estimate the proportion of ADC in invasive cervical cancer, the global number of cases of cervical ADC in 2015, the effect of cervical screening on ADC, the number of ADC cases attributable to high-risk HPV types -16, -18, -45, -31 and -33, and the potential impact of HPV vaccination using a variety of data sources including: GLOBOCAN 2008, Cancer Incidence in Five Continents (CI5) Volume IX, cervical screening data from the World Health Organization/Institut Català d'Oncologia Information Centre on HPV and cervical cancer, and published literature. Results ADC represents 9.4% of all ICC although its contribution varies greatly by country and region. The global crude incidence rate of cervical ADC in 2015 is estimated at 1.6 cases per 100,000 women, and the projected worldwide incidence of ADC in 2015 is 56,805 new cases. Current detection rates for HPV DNA in cervical ADC tend to range around 80–85%; the lower HPV detection rates in cervical ADC versus squamous cell carcinoma may be due to technical artefacts or to misdiagnosis of endometrial carcinoma as cervical ADC. Published data indicate that the five most common HPV types found in cervical ADC are HPV-16 (41.6%), -18 (38.7%), -45 (7.0%), -31 (2.2%) and -33 (2.1%), together comprising 92% of all HPV positive cases. Future projections using 2015 data, assuming 100% vaccine coverage and a true HPV causal relation of 100%, suggest that vaccines providing protection against HPV-16/18 may theoretically prevent 79% of new HPV-related ADC cases (44,702 cases annually) and vaccines additionally providing cross-protection against HPV-31/33/45 may prevent 89% of new HPV-related ADC cases (50,769 cases annually). Conclusions It is predicted that the currently available HPV vaccines will be highly effective in preventing HPV-related cervical ADC. PMID:24261839

2012-10-01

To describe health care providers' missed opportunities for preventing and treating congenital syphilis in New York City. Review of congenital syphilis cases reported to the New York City Department of Health and Mental Hygiene from January 1, 2000 to December 31, 2009. Receipt and timing of prenatal care, serologic testing, and treatment of mothers and newborns were reviewed. Missed opportunities were defined as receipt of prenatal care plus one of the following: 1) lack of documented treatment for syphilis infection diagnosed before pregnancy; 2) absence of serologic testing during pregnancy; 3) late maternal treatment; 4) maternal treatment with a nonpenicillin regimen; or 5) lack of maternal treatment. In total, 195 newborns with congenital syphilis were born to 190 mothers with 191 pregnancies. Overall, 80% (95% confidence interval [CI] 74-86%, 152 of 190) of all mothers received prenatal care; 63% (95% CI 56-71%, 96 of 152) of these had one or more missed opportunities for prevention. Twelve mothers received inadequate treatment or no treatment during the case pregnancy for documented syphilis infection before pregnancy, and 42 mothers without previous syphilis diagnosis did not have serologic testing during the case pregnancy. Of 103 mothers with syphilis diagnosed before 30 weeks of gestation, 12 received late penicillin therapy, 27 received no therapy, and 3 received inappropriate (nonpenicillin) therapy. Seventeen percent (95% CI 12-22%, 33 of 193) of liveborn newborns received no treatment during their hospitalization. Providers missed well-defined opportunities to prevent congenital syphilis for the majority of cases. Combined efforts to prevent future cases include provider education and better integration of care between obstetricians and pediatricians. III.

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.

Exposure to ultraviolet radiation from indoor tanning device use is associated with an increased risk of skin cancer, including risk of malignant melanoma, and is an urgent public health problem. By reducing indoor tanning, future cases of skin cancer could be prevented, along with the associated morbidity, mortality, and healthcare costs. On August 20, 2012, the CDC hosted a meeting to discuss the current body of evidence on strategies to reduce indoor tanning as well as research gaps. Using the Action Model to Achieve Healthy People 2020 Overarching Goals as a framework, the current paper provides highlights on the topics that were discussed, including (1) the state of the evidence on strategies to reduce indoor tanning; (2) the tools necessary to effectively assess, monitor, and evaluate the short- and long-term impact of interventions designed to reduce indoor tanning; and (3) strategies to align efforts at the national, state, and local levels through transdisciplinary collaboration and coordination across multiple sectors. Although many challenges and barriers exist, a coordinated, multilevel, transdisciplinary approach has the potential to reduce indoor tanning and prevent future cases of skin cancer. PMID:23683986

Making the economic case for prevention--a view from Wales.

PubMed

It is widely acknowledged that adverse lifestyle behaviours in the population now will place an unsustainable burden on health service resources in the future. It has been estimated that the combined cost to the NHS in Wales of overweight and obesity, alcohol and tobacco is in excess of £540 million.In the current climate of financial austerity, there can be a tendency for the case for prevention efforts to be judged on the basis of their scope for cost savings. This paper was prompted by discussion in Wales about the evidence for the cost savings from prevention and early intervention and a resulting concern that these programmes were thus being evaluated in policy terms using an incorrect metric. Following a review of the literature, this paper contributes to the discussion of the potential role that economics can play in informing decisions in this area. This paper argues that whilst studies of the economic burden of diseases provide information about the magnitude of the problem faced, they should not be used as a means of priority setting. Similarly, studies discussing the likelihood of savings as a result of prevention programmes may be distorting the arguments for public health.Prevention spend needs to be considered purposefully, resulting in a strategic commitment to spending. The role of economics in this process is to provide evidence demonstrating that information and support can be provided cost effectively to individuals to change their lifestyles thus avoiding lifestyle related morbidity and mortality. There is growing evidence that prevention programmes represent value for money using the currently accepted techniques and decision making metrics such as those advocated by NICE. The issue here is not one of arguing that the economic evaluation of prevention and early intervention should be treated differently, although in some instances that may be appropriate, rather it is about making the case for these interventions to be treated and evaluated to the same standard. The difficulty arises when a higher standard of cost saving may be expected from prevention and public health programmes.The paper concludes that it is of vital importance that during times of budget constraints, as currently faced, the public health budgets are not eroded to fund secondary care budget shortfalls, which are more easily identifiable. To do so would diminish any possibility of reducing the future burden faced by the NHS of lifestyle-related illnesses.

Early detection versus primary prevention in the PLCO flexible sigmoidoscopy screening trial: Which has the greatest impact on mortality?

Screening for colorectal cancer (CRC) with flexible sigmoidoscopy (FS) has been shown to reduce CRC mortality. The current study examined whether the observed mortality reduction was due primarily to the prevention of incident CRC via removal of adenomatous polyps or to the early detection of cancer and improved survival. The Prostate, Lung, Colorectal, and Ovarian (PLCO) cancer screening trial randomized 154,900 men and women aged 55 to 74 years. Individuals underwent FS screening at baseline and at 3 or 5 years versus usual care. CRC-specific survival was analyzed using Kaplan-Meier curves and proportional hazards modeling. The authors estimated the percentage of CRC deaths averted by early detection versus primary prevention using a model that applied intervention arm survival rates to CRC cases in the usual-care arm and vice versa. A total of 1008 cases of CRC in the intervention arm and 1291 cases of CRC in the usual-care arm were observed. Through 13 years of follow-up, there was no significant difference noted between the trial arms with regard to CRC-specific survival for all CRC (68% in the intervention arm vs 65% in the usual-care arm; P =.16) or proximal CRC (68% vs 62%, respectively; P = .11) cases; however, survival in distal CRC cases was found to be higher in the intervention arm compared with the usual-care arm (77% vs 66%; P<.0001). Within each arm, symptom-detected cases had significantly worse survival compared with screen-detected cases. Overall, approximately 29% to 35% of averted CRC deaths were estimated to be due to early detection and 65% to 71% were estimated to be due to primary prevention. CRC-specific survival was similar across arms in the PLCO trial, suggesting a limited role for early detection in preventing CRC deaths. Modeling suggested that approximately two-thirds of avoided deaths were due to primary prevention. Future CRC screening guidelines should emphasize primary prevention via the identification and removal of precursor lesions.

Complete Expulsion of Testicular Prosthesis via the Scrotum: A Case-Based Review of the Preventive Surgical Strategies

PubMed Central

Deb, A.; Jay Mathias, Suresh; Fraser Saxby, Mark; Fernando, Herman

2015-01-01

Testicular prostheses are regularly used in urological surgery and are important for postoperative psychological well-being in many patients undergoing orchiectomy. One of the recognised complications of this procedure is graft extrusion, which can result in significant morbidity for patients and require operative reintervention. Whilst most cases of extrusion involve upward graft migration to the external inguinal ring or direct displacement through the scrotal skin, we present an unusual case of complete expulsion of testicular implant three weeks postoperatively through a previously healthy scrotum. During surgical insertion of testicular prostheses, the urological surgeon must carefully consider the different surgical strategies at each step of the operation to prevent future extrusion of the graft. A stepwise review of the preventive surgical strategies to reduce the risk of graft extrusion encompasses the choice of optimal surgical incision, the technique of dissection to create the receiving anatomical pouch, the method of fixation of the implant within the receiving hemiscrotum, and the adoption of good postoperative care measures in line with the principles of sound scrotal surgery.

Prevention of suicidal behaviour is a public health priority in the European Union. A previous suicide attempt is the best risk predictor for future attempts, as well as completed suicides. The primary aim of this article is to describe a controlled study protocol designed for prevention of recurrent suicidal behaviour that proposes case management, and includes a psychoeducation program, as compared with the standard intervention (PSyMAC). Patients admitted from January 2011 to June 2013 to the emergency room of the Hospital Universitario Central de Asturias were evaluated using a protocol including sociodemographic, psychiatric, and psychosocial assessment. Patients were randomly assigned to either a group receiving continuous case management including participation in a psychoeducation program (experimental group), or a control group receiving standard care. The primary objective is to examine whether or not the period of time until recurrent suicidal behaviour in the experimental group is significantly different from that of the control group. PSyMAC proposes low cost and easily adaptable interventions to the usual clinical setting that can help to compensate the shortcoming of specific action protocols and suicidal behaviour prevention programs in our country. The evaluation of PSyMAC results will determine their real effectivity as a case-magament program to reduce suicidal risk. Copyright © 2013 SEP y SEPB. Published by Elsevier España.

To evaluate the cost effectiveness of genetic screening for the apolipoprotein (APOE) ε4 allele in combination with preventive donepezil treatment in comparison with the standard of care for amnestic mild cognitive impairment (AMCI) patients in Canada. We performed a cost-effectiveness analysis using a Markov model with a societal perspective and a time horizon of 30 years. For each strategy, we calculated quality-adjusted life-years (QALYs), using utilities from the literature. Costs were also based on the literature and, when appropriate, Ontario sources. One-way and probabilistic sensitivity analyses were performed. Expected value of perfect information (EVPI) analysis was conducted to explore the value of future research. The base case results in our exploratory study suggest that the combination of genetic testing and preventive donepezil treatment resulted in a gain of 0.027 QALYs and an incremental cost of $1,015 (in 2009 Canadian dollars [Can$]), compared with the standard of care. The incremental cost-effectiveness ratio (ICER) for the base case was Can$38,016 per QALY. The ICER was sensitive to the effectiveness of donepezil in slowing the rate of progression to Alzheimer's disease (AD), utility in AMCI patients, and AD and donepezil treatment costs. EVPI analysis showed that additional information on these parameters would be of value. Using presently available clinical evidence, this exploratory study illustrates that genetic testing combined with preventive donepezil treatment for AMCI patients may be economically attractive. Since our results were based on a secondary post hoc analysis, our study alone is insufficient to warrant recommending APOE genotyping in AMCI patients. Future research on the effectiveness of preventive donepezil as a targeted therapy is recommended.

Cost-effectiveness of HIV counseling and testing in US prisons.

The prevalence of human immunodeficiency virus (HIV) in correctional facilities is much higher than in the general population. However, HIV prevention resources are limited, making it important to evaluate different prevention programs in prison settings. Our study presents the cost-effectiveness of offering HIV counseling and testing (CT) to soon-to-be-released inmates in US prisons. A decision model was used to estimate the costs and benefits (averted HIV cases) of HIV testing and counseling compared to no CT from a societal perspective. Model parameters were HIV prevalence among otherwise untested inmates (1%); acceptance of CT (50%); risk for HIV transmission from infected individuals (7%); risk of HIV acquisition for uninfected individuals (0.3%); and reduction of risk after counseling for those infected (25%) and uninfected (20%). Marginal costs of testing and counseling per person were used (no fixed costs). If infected, the cost was $78.17; if uninfected, it was $24.63. A lifetime treatment cost of $186,900 was used to estimate the benefits of prevented HIV infections. Sensitivity and threshold analysis were done to test the robustness of these parameters. Our baseline model shows that, compared to no CT, offering CT to 10,000 inmates detects 50 new or previously undiagnosed infections and averts 4 future cases of HIV at a cost of $125,000 to prison systems. However, this will save society over $550,000. Increase in HIV prevalence, risk of transmission, or effectiveness of counseling increased societal savings. As prevalence increases, focusing on HIV-infected inmates prevents additional future infections; however, when HIV prevalence is less than 5%, testing and counseling of both infected and uninfected inmates are important for HIV prevention.

Excessive summer heat is a serious environmental health problem in several European cities. Heat-related mortality and morbidity is likely to increase under climate change scenarios without adequate prevention based on locally relevant evidence. We modelled the urban climate of Antwerp for the summer season during the period 1986-2015, and projected summer daily temperatures for two periods, one in the near (2026-2045) and one in the far future (2081-2100), under the Representative Concentration Pathway (RCP) 8.5. We then analysed the relationship between temperature and mortality, as well as with hospital admissions for the period 2009-2013, and estimated the projected mortality in the near future and far future periods under changing climate and population, assuming alternatively no acclimatization and acclimatization based on a constant threshold percentile temperature. During the sample period 2009-2013 we observed an increase in daily mortality from a maximum daily temperature of 26°C, or the 89th percentile of the maximum daily temperature series. The annual average heat-related mortality in this period was 13.4 persons (95% CI: 3.8-23.4). No effect of heat was observed in the case of hospital admissions due to cardiorespiratory causes. Under a no acclimatization scenario, annual average heat-related mortality is multiplied by a factor of 1.7 in the near future (24.1deaths/year CI 95%: 6.78-41.94) and by a factor of 4.5 in the far future (60.38deaths/year CI 95%: 17.00-105.11). Under a heat acclimatization scenario, mortality does not increase significantly in the near or in the far future. These results highlight the importance of a long-term perspective in the public health prevention of heat exposure, particularly in the context of a changing climate, and the calibration of existing prevention activities in light of locally relevant evidence.

The overall age-standardized cancer incidence rate continues to decline whereas the number of cases diagnosed each year increases. Predicting cancer incidence can help to anticipate future resource needs, evaluate primary prevention strategies, and inform research. Surveillance, Epidemiology, and End Results data were used to estimate the number of cancers (all sites) resulting from changes in population risk, age, and size. The authors projected to 2020 nationwide age-standardized incidence rates and cases (including the top 23 cancers). Since 1975, incident cases increased among white individuals, primarily caused by an aging white population, and among black individuals, primarily caused by an increasing black population. Between 2010 and 2020, it is expected that overall incidence rates (proxy for risk) will decrease slightly among black men and stabilize in other groups. By 2020, the authors predict annual cancer cases (all races, all sites) to increase among men by 24.1% (-3.2% risk and 27.3% age/growth) to >1 million cases, and by 20.6% among women (1.2% risk and 19.4% age/growth) to >900,000 cases. The largest increases are expected for melanoma (white individuals); cancers of the prostate, kidney, liver, and urinary bladder in males; and the lung, breast, uterus, and thyroid in females. Overall, the authors predict cancer incidence rates/risk to stabilize for the majority of the population; however, they expect the number of cancer cases to increase by >20%. A greater emphasis on primary prevention and early detection is needed to counter the effect of an aging and growing population on the burden of cancer. © 2015 American Cancer Society.

Electrical stimulation (ES) can confer benefit to pressure ulcer (PU) prevention and treatment in spinal cord injuries (SCIs). However, clinical guidelines regarding the use of ES for PU management in SCI remain limited. To critically appraise and synthesize the research evidence on ES for PU prevention and treatment in SCI. Review was limited to peer-reviewed studies published in English from 1970 to July 2013. Studies included randomized controlled trials (RCTs), non-RCTs, prospective cohort studies, case series, case control, and case report studies. Target population included adults with SCI. Interventions of any type of ES were accepted. Any outcome measuring effectiveness of PU prevention and treatment was included. Methodological quality was evaluated using established instruments. Twenty-seven studies were included, 9 of 27 studies were RCTs. Six RCTs were therapeutic trials. ES enhanced PU healing in all 11 therapeutic studies. Two types of ES modalities were identified in therapeutic studies (surface electrodes, anal probe), four types of modalities in preventive studies (surface electrodes, ES shorts, sacral anterior nerve root implant, neuromuscular ES implant). The methodological quality of the studies was poor, in particular for prevention studies. A significant effect of ES on enhancement of PU healing is shown in limited Grade I evidence. The great variability in ES parameters, stimulating locations, and outcome measure leads to an inability to advocate any one standard approach for PU therapy or prevention. Future research is suggested to improve the design of ES devices, standardize ES parameters, and conduct more rigorous trials.

We gathered seven specialists from various fields who are interested in worker injury prevention programs, based on cases of patients who had suffered refractory injuries requiring hand surgery because of industrial accidents. The patients were asked to write their thoughts and ideas on the theme, "Measures that must be implemented to prevent arm injuries." The content obtained was classified into different categories, using the KJ method, and was scripted to sort out the items. As a result, the following eleven points were identified as measures to prevent serious hand surgery-related injuries: 1. Purchase safe machinery, 2. Create a list of machines that require caution, 3. Enclose a machine's various rotating parts, 4. Carry out periodic maintenance work on the machines, 5. Indicate dangerous areas by putting up signs that attract attention, 6. Illuminate the rotating parts more brightly and avoid placing objects around them, 7. Systematically carry out safety education that creates a strong impact, 8. Encourage workers to look after their own health, 9. Announce policies on health and safety, 10. Re-examine the operational procedures, and 11. Be prepared in case an accident occurs. A perspective based on the results of this research is deemed important in creating a workplace improvement manual in the future.

Immediately modifiable risk factors attributable to colorectal cancer in Malaysia.

Naing, Cho; Lai, Pei Kuan; Mak, Joon Wah

2017-08-04

This study aimed to estimate potential reductions in case incidence of colorectal cancer attributable to the modifiable risk factors such as alcohol consumption, overweight and physical inactivity amongst the Malaysian population. Gender specific population-attributable fractions (PAFs) for colorectal cancer in Malaysia were estimated for the three selected risk factors (physical inactivity, overweight, and alcohol consumptions). Exposure prevalence were sourced from a large-scale national representative survey. Risk estimates of the relationship between the exposure of interest and colorectal cancer were obtained from published meta-analyses. The overall PAF was then estimated, using the 2013 national cancer incidence data from the Malaysian Cancer Registry. Overall, the mean incidence rate for colorectal cancer in Malaysia from 2008 to 2013 was 21.3 per 100,000 population, with the mean age of 61.6 years (±12.7) and the majority were men (56.6%). Amongst 369 colorectal cancer cases in 2013, 40 cases (20 men, 20 women), 10 cases (9 men, 1 woman) or 20 cases (16 men,4 women) would be prevented, if they had done physical exercises, could reduce their body weight to normal level or avoided alcohol consumption, assuming that these factors are causally related to colorectal cancer. It was estimated that 66 (17.8%;66/369) colorectal cancer cases (42 men, 24 women) who had all these three risk factors for the last 10 years would have been prevented, if they could control these three risk factors through effective preventive measures. Findings suggest that approximately 18% of colorectal cancer cases in Malaysia would be prevented through appropriate preventive measures such as doing regular physical exercises, reducing their body weight to normal level and avoiding alcohol consumption, if these factors are causally related to colorectal cancer. Scaling-up nationwide public health campaigns tailored to increase physical activity, controlling body weight within normal limits and avoid alcohol intake are recommended. Future studies with other site-specific cancers and additional risk factors are needed.

Jet Fuel-Associated Occupational Contact Dermatitis.

PubMed

Contestable, James J

2017-03-01

Occupational contact dermatitis is a ubiquitous problem. Sailors onboard U.S. Navy vessels are at high risk given the multitude of potential workplace exposures. Solvents, petrochemicals, and fuels are abundant and can cause irritant or allergic contact dermatitis. Symptoms of contact dermatitis can cause inability to work and, if chronic, may require a change in rating or job. Prevention of this issue requires patient education about the risks and correct personnel protective equipment. Even with preventative strategies in place, exposures and cases of contact dermatitis will occur. Treatment consists of topical steroids and immunomodulators, as well as barrier creams and emollients. The goal of treatment is to fully restore the skin's natural barrier and prevent further exposure. A classic case of jet fuel-associated contact dermatitis is reviewed. A literature review utilizing PubMed, Google Scholar, and Google Search was conducted to elucidate our understanding of this issue, current occupational health guidelines, preventative approaches, and treatments. This case report provides guidance and recommendations for providers who encounter contact dermatitis related to petrochemicals, such as jet fuel. The literature review revealed limited knowledge surrounding in vivo human skin effects of jet fuel, specifically JP-5. Even larger gaps were found in our understanding of, and guidelines for, protective modalities against jet fuel exposure and dermatitis. A case is presented to facilitate recognition of jet fuel contact dermatitis and guidance for treatment and prevention. Given our current limited knowledge and guidelines concerning protective equipment and skin protectants, multiple proposals for future studies are suggested.

In 2006, we conducted case studies of 4 North Carolina local health departments (LHDs) that scored highly on an index of diabetes prevention and control performance, to explore characteristics that may serve as barriers or facilitators of diabetes prevention and control services. Case studies involving in-depth interviews were conducted at 4 LHDs. Sites were selected on the basis of 2 variables, known external funding for diabetes services and population size, that were associated with performance in diabetes prevention and control in a 2005 survey of all North Carolina LHDs. Fourteen interviews (individual and group) were conducted among 17 participants from the 4 LHDs. The main outcome measures were LHD characteristics that facilitate or hinder the performance of diabetes programs and services. Interviews revealed that all 4 high-performing LHDs had received some sort of funding from a source external to the LHD. Case study participants indicated that barriers to additional service delivery included low socioeconomic status of the population and lack of financial resources. Having a diabetes self-management education program that was recognized by the American Diabetes Association appeared to be a facilitator of diabetes services provision. Other facilitators were leadership and staff commitment, which appeared to facilitate the leveraging of partnerships and funding opportunities, leading to enhanced service delivery. The small number of LHDs participating in the study and the cross-sectional study design were limitations. Leadership, staff commitment, partnership leveraging, and funding appear to be associated with LHD performance in diabetes prevention and control services. These factors should be further studied in future public health systems and services research.

Solid organ transplant recipients have a higher frequency of tuberculosis (TB) than the general population, with mortality rates of approximately 30%. Although donor-derived TB is reported to account for <5% of TB in solid organ transplants, the source of Mycobacterium tuberculosis infection is infrequently determined. We report 3 new cases of pulmonary TB in lung transplant recipients attributed to donor infection, and review the 12 previously reported cases to assess whether cases could have been prevented and whether any cases that might occur in the future could be detected and investigated more quickly. Specifically, we evaluate whether opportunities existed to determine TB risk on the basis of routine donor history, to expedite diagnosis through routine mycobacterial smears and cultures of respiratory specimens early post transplant, and to utilize molecular tools to investigate infection sources epidemiologically. On review, donor TB risk was present among 7 cases. Routine smears and cultures diagnosed 4 asymptomatic cases. Genotyping was used to support epidemiologic findings in 6 cases. Validated screening protocols, including microbiological testing and newer technologies (e.g., interferon-gamma release assays) to identify unrecognized M. tuberculosis infection in deceased donors, are warranted. © 2014 John Wiley & Sons A/S.

Introduction During May 2012, a rubella outbreak was declared in Solomon Islands. A suspected case of congenital rubella syndrome (CRS) was reported from one hospital 11 months later in 2013. This report describes the subsequent CRS investigation, findings and measures implemented. Methods Prospective CRS surveillance was conducted at the newborn nursery, paediatric and post-natal wards, and the paediatric cardiology and ophthalmology clinics of the study hospital from April to July 2013. Retrospective case finding by reviewing medical records was also undertaken to identify additional cases born between January and March 2013 for the same wards and clinics. Cases were identified using established World Health Organization case definitions for CRS. Results A total of 13 CRS cases were identified, including two laboratory-confirmed, four clinically confirmed and seven suspected cases. Five CRS cases were retrospectively identified, including four suspected and one clinically confirmed case. There was no geospatial clustering of residences. The mothers of the cases were aged between 20 and 36 years. Three of the six mothers available for interview recalled an acute illness with rash during the first trimester of pregnancy. Discussion Additional CRS cases not captured in this investigation are likely. Caring for CRS cases is a challenge in resource-poor settings. Rubella vaccination is safe and effective and can prevent the serious consequences of CRS. Well planned and funded vaccination activities can prevent future CRS cases. PMID:27757248

Five CRS cases were retrospectively identified, including four suspected and one clinically confirmed case. There was no geospatial clustering of residences. The mothers of the cases were aged between 20 and 36 years. Three of the six mothers available for interview recalled an acute illness with rash during the first trimester of pregnancy. Additional CRS cases not captured in this investigation are likely. Caring for CRS cases is a challenge in resource-poor settings. Rubella vaccination is safe and effective and can prevent the serious consequences of CRS. Well planned and funded vaccination activities can prevent future CRS cases.

The Regional Infant and Child Mortality Review Committee serves 10 counties in southeastern South Dakota and aims to use its reviews to prevent future loss of life during childhood. In 2015, the committee reviewed 24 deaths (compared to 32 cases in 2013 and 25 cases in 2014). Consistent with observations made in previous years, in 2015 all infants (n=7) who died during sleep did so with risks present in the sleep environment. Progress in decreasing these infant deaths in the region is not being observed, and in fact, may even be deteriorating. Two children died subsequent to a motor vehicle crash and neither were wearing a seat belt. The committee was pleased, however, to note that there were no childhood fatalities associated with teenaged drivers. One teen suicide in 2015 marked a decrease in the number observed in 2013 and 2014, but represents an ongoing concern about the safety of emotionally volatile adolescents. Further, one child homicide occurred in the region in 2015 reflecting the fragility of young in the presence of stressed and unstable home environments. The report provides the committee's recommendation for community action that could prevent future deaths of infants and children. Copyright© South Dakota State Medical Association.

Making the economic case for prevention – a view from Wales

PubMed Central

2012-01-01

Background It is widely acknowledged that adverse lifestyle behaviours in the population now will place an unsustainable burden on health service resources in the future. It has been estimated that the combined cost to the NHS in Wales of overweight and obesity, alcohol and tobacco is in excess of £540 million. In the current climate of financial austerity, there can be a tendency for the case for prevention efforts to be judged on the basis of their scope for cost savings. This paper was prompted by discussion in Wales about the evidence for the cost savings from prevention and early intervention and a resulting concern that these programmes were thus being evaluated in policy terms using an incorrect metric. Following a review of the literature, this paper contributes to the discussion of the potential role that economics can play in informing decisions in this area. Discussion This paper argues that whilst studies of the economic burden of diseases provide information about the magnitude of the problem faced, they should not be used as a means of priority setting. Similarly, studies discussing the likelihood of savings as a result of prevention programmes may be distorting the arguments for public health. Prevention spend needs to be considered purposefully, resulting in a strategic commitment to spending. The role of economics in this process is to provide evidence demonstrating that information and support can be provided cost effectively to individuals to change their lifestyles thus avoiding lifestyle related morbidity and mortality. There is growing evidence that prevention programmes represent value for money using the currently accepted techniques and decision making metrics such as those advocated by NICE. Summary The issue here is not one of arguing that the economic evaluation of prevention and early intervention should be treated differently, although in some instances that may be appropriate, rather it is about making the case for these interventions to be treated and evaluated to the same standard. The difficulty arises when a higher standard of cost saving may be expected from prevention and public health programmes. The paper concludes that it is of vital importance that during times of budget constraints, as currently faced, the public health budgets are not eroded to fund secondary care budget shortfalls, which are more easily identifiable. To do so would diminish any possibility of reducing the future burden faced by the NHS of lifestyle-related illnesses. PMID:22716189

Health education and promotion for STD prevention: lessons for the next millennium.

PubMed Central

Darrow, W W

1997-01-01

OBJECTIVE: To review the evolution of health promotion for STD prevention. MAIN OBSERVATIONS: Information and education programmes were provided at the beginning of the 20th century to warn the public about the dangers of venereal infection and to support the medical model of case identification and case management under the care of qualified physicians. The public health approach offered advice about chemical, chemotherapeutic, and barrier prophylaxis, but avoided the issue of social prophylaxis. With the failure of antimicrobial agents to eradicate syphilis in the 1960s, rapid increases of viral sexually transmitted diseases (STDs) and resistant strains of gonorrhoea in the 1970s, and the discovery of AIDS in the 1980s, alternatives to the traditional public health approach were sought and supported with a modest increase of resources. Three major innovations have been introduced to STD prevention as a result: social marketing, community involvement, and behaviour change programmes based on social and psychological concepts and theoretical models. CONCLUSIONS: Health promotion for STD prevention in the future will be characterised by careful assessments of the social and behavioural determinants of sexual risk taking, development and implementation of targeted interventions designed to reduce risk taking, and evaluation of social and behavioural interventions for improvements in STD prevention.

In-depth assessment of an outbreak of Nipah encephalitis with person-to-person transmission in Bangladesh: implications for prevention and control strategies.

Blum, Lauren S; Khan, Rasheda; Nahar, Nazmun; Breiman, Robert F

2009-01-01

Continued Nipah encephalitis outbreaks in Bangladesh highlight the need for preventative and control measures to reduce transmission from bats to humans and human-to-human spread. Qualitative research was conducted at the end of an encephalitis outbreak in Faridpur, Bangladesh in May 2004 and continued through December 2004. Methods included in-depth interviews with caretakers of cases, case survivors, neighbors of cases, and health providers. Results show contrasts between local and biomedical views on causal explanations and appropriate care. Social norms demanded that family members maintain physical contact with sick patients, potentially increasing the risk of human-to-human transmission. Initial treatment strategies by community members involved home remedies, and public health officials encouraged patient hospitalization. Over time, communities linked the outbreak to supernatural powers and sought care with spiritual healers. Differing popular and medical views of illness caused conflict and rejection of biomedical recommendations. Future investigators should consider local perceptions of disease and treatment when developing outbreak strategies.

Soldiers based in Townsville, Australia, returned from East Timor following peacekeeping operations during the wet season of 1999 to 2000. This represented the potential to import dengue virus into north Queensland, a dengue receptive area of Australia. This article seeks to outline the measures taken by the Australian Defence Force (ADF) to prevent local transmission and to present the outcomes. Soldiers returning to north Queensland were provided with education on dengue fever and in the fortnight before return, their living areas were subjected to intensive vector control measures, in order to reduce the risk of acquisition of dengue. They were further encouraged to present early with any febrile illness following their return to Townsville. Provisionally diagnosed dengue cases were notified to the state public health authorities immediately and cases were isolated until suitable vector control programs were implemented or the potentially viremic period exceeded. Serologic and virologic investigations were undertaken to identify the passage and probable serotype or confirm the presence and serotype of dengue virus. Nine serologically confirmed cases of dengue were identified as viremic in north Queensland. Six cases were identified as arising from dengue serotype 2, two were from serotype 3, and one case was ill defined. No dengue cases have been reported in the local population 4 months following these ADF cases. Local outbreaks of dengue fever have occurred in north Queensland following the importation of dengue virus in returned travelers. The successful prevention of local transmission in these circumstances was contributed to by early notification of cases and prevention of transmission through isolation of cases and collaboration between ADF and state and local public health authorities in vector control. The management of potentially viremic returning service personnel represents a future challenge for the ADF.

West Nile Virus (WNV) is the causative agent of a vector-borne, zoonotic disease with a worldwide distribution. Recent expansion and introduction of WNV into new areas, including southern Europe, has been associated with severe disease in humans and equids, and has increased concerns regarding the need to prevent and control future WNV outbreaks. Since 2010, 524 confirmed human cases of the disease have been reported in Greece with greater than 10% mortality. Infected mosquitoes, wild birds, equids, and chickens have been detected and associated with human disease. The aim of our study was to establish a monitoring system with wild birds and reported human cases data using Geographical Information System (GIS). Potential distribution of WNV was modelled by combining wild bird serological surveillance data with environmental factors (e.g. elevation, slope, land use, vegetation density, temperature, precipitation indices, and population density). Local factors including areas of low altitude and proximity to water were important predictors of appearance of both human and wild bird cases (Odds Ratio = 1,001 95%CI = 0,723-1,386). Using GIS analysis, the identified risk factors were applied across Greece identifying the northern part of Greece (Macedonia, Thrace) western Greece and a number of Greek islands as being at highest risk of future outbreaks. The results of the analysis were evaluated and confirmed using the 161 reported human cases of the 2012 outbreak predicting correctly (Odds = 130/31 = 4,194 95%CI = 2,841-6,189) and more areas were identified for potential dispersion in the following years. Our approach verified that WNV risk can be modelled in a fast cost-effective way indicating high risk areas where prevention measures should be implemented in order to reduce the disease incidence.

2017-04-24

Over 85% of cervical cancer cases and deaths occur in developing countries. HIV-seropositive women are more likely to develop precancerous lesions that lead to cervical cancer than HIV-negative women. However, the literature on cervical cancer prevention in seropositive women in developing countries has not been reviewed. The aim of this study is to systematically review cervical cancer prevention modalities available for HIV-seropositive women in developing countries. This protocol was developed by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) statement, and the systematic review will be reported in accordance with the PRISMA guidelines. Embase, MEDLINE, PubMed, CINAHL and Cochrane Library will be searched from inception up to date of final search, and additional studies will be located through citation and reference list tracking. Eligible studies will be randomised controlled trials, prospective and retrospective cohort studies, case-control and cross-sectional studies carried out in developing countries. Studies will be included if they are published in English and examine cervical cancer prevention modalities in HIV-seropositive women. Results will be summarised in tables and, where appropriate, combined using meta-analysis. This review will address the gap in evidence by systematically reviewing the published literature on the different prevention modalities being used to prevent cervical cancer in HIV-seropositive women in developing countries. The findings may be used to inform evidence-based guidelines for prevention of cervical cancer in seropositive women as well as future research. PROSPERO CRD42017054678 .

This study presents an analysis of AIDS cases and seroprevalence of HIV infection among Mexican women, from the onset of the epidemic through June 1994, as well as the analysis of the social and cultural factors that put women in a powerless situation regarding the adoption of preventive measures. Since 1985, when the first AIDS cases among women were reported in Mexico and until June 1, 1994, a total of 2,767 cases have been reported, representing 14.8% of the total number of cases. The first cases of AIDS among women were associated to infected blood transfusions; however, in 1986, heterosexually transmitted cases began to appear. Currently, only 35% of newly reported AIDS cases are associated to blood transfusions while 64% of them are related to heterosexual transmission. In fact, two epidemics are evident: one transmitted through blood, showing a downward trend (duplication time 45 months), and a second one, heterosexually transmitted, increasing twice as fast (duplication time 27 months). The latter is expected to dominate AIDS epidemiology among women in the future. In general, women are more vulnerable to HIV/AIDS biologically, but also socially and culturally. Women's economic, social and cultural subordination to their sexual partners results in a situation that makes it difficult for them to assess their infection risk and even more, to negotiate taking preventive measures. This situation is even more disadvantageous to rural women and, together with the recent trend of the AIDS epidemic to ruralization and with internal and international migration (temporary work force migration to the USA), can result in deep demographic and social effects. We conclude that it is necessary to work on the design and assessment of preventive measures under women's control, that empower them to protect themselves even without their partner's awareness. Also, it is necessary to promote sexual education among young heterosexual couples on how to talk about sexual issues and negotiate the use of preventive measure according to their actual sexual practices.

Tobacco smoking is a leading cause of cancer and the most preventable cause of cancer worldwide. The aim of this study was to quantify the proportion of the cancer burden in the Nordic countries linked to tobacco smoking and estimate the potential for cancer prevention by changes in smoking prevalence. The Prevent macro-simulation model was used, estimating the future number of cancer cases in the Nordic countries over a 30-year period (2016-2045), for 13 cancer sites, under different scenarios of changing smoking prevalence, and compared to the projected number of cases if constant prevalence prevailed. A total of 430,000 cancer cases, of the 2.2 million expected for the 13 studied cancer sites, could be avoided in the Nordic countries over the 30-year period if smoking was eliminated from 2016 onwards. If prevalence of smoking is reduced to 5% by year 2030 and to 2% by 2040, 230,000 cancer cases could be avoided. The largest proportion of cancers can be avoided in Denmark, where smoking prevalence is the highest, and similar to the prevalence in many European countries. A large amount of cancers could be avoided in the Nordic countries if smoking prevalence was reduced. The results from this study can be used to understand the potential impact and significance of primary prevention programmes targeted towards reducing the prevalence of tobacco smoking in the Nordic countries.

Kjellberg, Göran

2010-03-24

The high number of divorces could partly be attributed to a lack of sexual desire in the couples linked to the prevailing sexual hyperstimulation in society. Sexual harassment on the internet and the exposition of abuse incidents in the mass media contribute to the increased numbers of child sexual abuse. Enhanced awareness among adults about the potential dangers of television and the internet, as well as psychotherapeutic treatment of abusers and their victims would be of preventative importance. Psychotherapeutic treatment of adolescents in situations of developmental "break-down" could result in a more mature sexuality contributing to fewer cases of sexual abuse and to the stabilisation of future couples on the long-term.

The Montreal Protocol was signed 25 years ago. As a result, the irreversible destruction of the ozone layer was prevented. However, stratospheric ozone will not recover completely until 2060 and the consequent epidemic in skin cancer cases will persist until 2100. Many millions of patients with asthma and chronic obstructive pulmonary disease have safely switched from chlorofluorocarbon (CFC)-powered metered-dose inhalers (MDIs) to either hydrofluorocarbon (HFC) or DPIs. China will be the last country to phase out CFCs by 2016. HFCs are global warming gases which will be controlled in the near future. HFCs in MDIs may be phased out over the next 10-20 years.

Combating child homicide: preventive policing for the new millennium.

High-profile media coverage of crimes against children has heightened public awareness of critical child safety needs and issues. However, numerous research studies in the area of child homicide have illustrated the importance of the power of science to correct false perceptions and misinformation, improving how to best serve and protect our children. Age-based analyses of childhood crime patterns have vastly improved how law enforcement and social service practitioners identify, investigate, and resolve child victimization cases. Future protective efforts must involve multiagency and multidisciplinary collaboration. Law enforcement, social service clinicians, educators, and academicians should jointly develop and implement pragmatic and effective prevention, detection, and resolution programs and policies.

Hesitance towards voluntary medical male circumcision in Lesotho: reconfiguring global health governance.

PubMed

Bulled, Nicola L

2015-01-01

Drawing on work examining HIV prevention initiatives in Lesotho, this paper considers the hesitation of national state actors towards the new strategy for HIV prevention - voluntary medical male circumcision (VMMC). Lesotho offers a representative case study on global health governance, given the country's high HIV burden and heavy dependence on foreign donor nations to implement local HIV prevention initiatives. In this paper, I use the case of VMMC opposition in Lesotho to examine how the new era of 'partnerships' has shifted the architecture of contemporary global health, specifically considering how global agreements are translated or negotiated into local practice. I argue that Lesotho's domestic policy-makers, in employing national statistics to assess if VMMC is an effective approach to addressing the local epidemic, are asserting a claim of expertise. In doing so, they challenge the traditional structures of global health politics, which have largely been managed by experts and funders from and in the global North. I explore the development of global VMMC policy, what drives Lesotho's resistance to comply, and consider the impact renegotiation efforts may have on future global health architecture.

Myotonic dystrophy is a genetic muscular disease that is frequently associated with cardiac arrhythmias. Bradyarrhythmias, such as sinus bradycardia and atrioventricular block, are more common than tachyarrhythmias. Rarely, previously undiagnosed patients with myotonic dystrophy initially present with a tachyarrhythmia. We describe the case of a 14-year-old boy, who was admitted to the hospital with clinical signs and symptoms of decompensated heart failure and severely reduced left ventricular function. Electrocardiography showed common-type atrial flutter with 2 : 1 conduction resulting in a heart rate of 160 bpm. Initiation of medical therapy for heart failure as well as electrical cardioversion led to a marked clinical improvement. Catheter ablation of atrial flutter was performed to prevent future cardiac decompensations and to prevent development of tachymyopathy. Left ventricular function normalized during followup. Genetic analysis confirmed the clinical suspicion of myotonic dystrophy as known in other family members in this case. PMID:20871860

This study aims to evaluate the effectiveness of pre-travel counselling carried out in Travel Clinics. This is a retrospective cohort. Three hundred international travellers were enrolled; 150 people were from users of Bari Travel Clinic, 150 were users of a travel agency. Enrolled subjects were interviewed using a questionnaire. The average age of the enrolled subjects was 37.5 ± 13.9, without statistically significant differences between the two groups. 86% of cases and 19.3% of the controls reported the use of anti-malaria prophylaxis (p < 0.0001). Vaccination against cholera was given to 62% of cases and 7.3% of the controls (p < 0.001). Travel Clinic users, 6% reported diarrhoea and these figures were 27% in the control group (p < 0.0001). The proportion of those interviewed who reported fever (3.7) or insomnia (1.3) did not differ between the two groups. Mosquito bites were reported by 8% of cases and 20% of the controls (p = 0.003). Three cases of malaria were reported among the controls but no cases were detected among the cases (chi-square = 3.03; p = 0.08). Our study demonstrated the effectiveness of pre-travel counselling; in the future, new studies must investigate the cost-effectiveness of pre-travel prevention measures.

The present study aimed to investigate the moderating effect of age on the relationship between future time perspective (FTP) and future-oriented coping. A total of 1,915 participants aged 9-84 years completed measures of FTP and future-oriented coping. Moderation analyses were conducted to examine whether age played a role in the association between FTP and future-oriented coping (proactive and preventive). Results showed that proactive and preventive coping were negatively correlated with age, and age moderated the association between FTP and preventive coping but not proactive coping. Furthermore, the strength of the positive association between FTP and preventive coping was strongest among the older participants, moderate among the middle-aged participants, and weakest among the younger participants. These results suggest that the association between FTP and preventive coping varies across the lifespan. © 2017 The Institute of Psychology, Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

KIDNEY STONES: AN UPDATE ON CURRENT PHARMACOLOGICAL MANAGEMENT AND FUTURE DIRECTIONS

Introduction Kidney stones are a common problem worldwide with substantial morbidities and economic costs. Medical therapy reduces stone recurrence significantly. Much progress has been made in the last several decades in improving therapy of stone disease. Areas covered 1) effect of medical expulsive therapy on spontaneous stone passage, 2) pharmacotherapy in the prevention of stone recurrence, 3) future directions in the treatment of kidney stone disease. Expert Opinion fluid intake to promote urine volume of at least 2.5L each day is essential to prevent stone formation. Dietary recommendations should be adjusted based on individual metabolic abnormalities. Properly dosed thiazide treatment is the standard therapy for calcium stone formers with idiopathic hypercalciuria. Potassium alkali therapy is considered for hypocitraturia, but caution should be taken to prevent potential risk of calcium phosphate stone formation. For absorptive hyperoxaluria, low oxalate diet and increased dietary calcium intake are recommended. Pyridoxine has been shown effective in some cases of primary hyperoxaluria type I. Allopurinol is used in calcium oxalate stone formers with hyperuricosuria. Treatment of cystine stones remains challenging. Tiopronin can be used if urinary alkalinization and adequate fluid intake are insufficient. For struvite stones, complete surgical removal coupled with appropriate antibiotic therapy is necessary.

The aim of all medical treatment is "primum nihil nocere" ("First, do no harm").Restoring the integrity of intestinal microbiota and optimising the immune response in recurrent infections, especially in the urinary tract, are treatment alternatives which are closer to this target than the usual focus on antibiotic prevention of recurrence.In the future, antibiotics will continue to be recommended for the prevention of urinary tract infections on a case-by-case basis. However, the problems of an excessive use of antibiotics, e. g. resistance and long-term interference with intestinal microbiota, are forcing us to search for alternatives. The use of probiotics alone or in combination with immunotherapeutics, or the sole use of immunotherapeutics, are important treatment options, which are already routinely available in clinical practice. These therapies are focused on the pathomechanism of an infection and tackle the root cause of the problem. Phytotherapeutics or small molecules like mannose, which restricts the adherence of bacteria to the urothelium, are complementary approaches.The EAU guidelines recommend the following treatments for the long-term prevention of urinary tract infections:Oral and parenteral immunostimulants (StroVac(®)), local estrogen replacement and administration of Lactobacillus rhamnosus and Lactobacillus reuteri. © Georg Thieme Verlag KG Stuttgart · New York.

Application of forensic image analysis in accident investigations.

PubMed

Verolme, Ellen; Mieremet, Arjan

2017-09-01

Forensic investigations are primarily meant to obtain objective answers that can be used for criminal prosecution. Accident analyses are usually performed to learn from incidents and to prevent similar events from occurring in the future. Although the primary goal may be different, the steps in which information is gathered, interpreted and weighed are similar in both types of investigations, implying that forensic techniques can be of use in accident investigations as well. The use in accident investigations usually means that more information can be obtained from the available information than when used in criminal investigations, since the latter require a higher evidence level. In this paper, we demonstrate the applicability of forensic techniques for accident investigations by presenting a number of cases from one specific field of expertise: image analysis. With the rapid spread of digital devices and new media, a wealth of image material and other digital information has become available for accident investigators. We show that much information can be distilled from footage by using forensic image analysis techniques. These applications show that image analysis provides information that is crucial for obtaining the sequence of events and the two- and three-dimensional geometry of an accident. Since accident investigation focuses primarily on learning from accidents and prevention of future accidents, and less on the blame that is crucial for criminal investigations, the field of application of these forensic tools may be broader than would be the case in purely legal sense. This is an important notion for future accident investigations. Copyright © 2017 Elsevier B.V. All rights reserved.

Measles remains a leading vaccine-preventable cause of child mortality worldwide. The impact of vaccination programs can be seen in the increasingly low incidence of measles. However, cases of measles continue to occur in low numbers every year in Taiwan. We assessed the epidemiology of measles in Taiwan from 1999 to 2008 with a focus on domestic versus imported cases. We analyzed the data reported to surveillance systems at the Taiwan Center for Disease Control, where viral isolation was performed. A total of 84 measles cases were reported from 1999 to 2008 in Taiwan with the incidence of measles varying from 0 to 1.5 per 1,000,000 people per year, peaking in 2002 and again in 2008. The incidence decreased with increasing age in both males and females. Among the 84 reported measles cases, 39 (46%) originated internationally, 8 (10%) were epidemiologically linked to imported cases and the source was unknown in 37 (44%) of the cases. The unknown-source cases were analyzed for potential evidence of endemic measles transmission. Most of the measles cases that occurred in Taiwan from 1999 to 2008 were associated with imported cases. No endemic transmission of measles in Taiwan was identified. This study suggests that maintaining the high rate of vaccination coverage is needed to prevent future outbreak and sustain the elimination of measles in Taiwan. (c) 2010 Elsevier Ltd.

Professional responsibility in elder law: a synthesis of preventive law and therapeutic jurisprudence.

PubMed

Stolle, D P

1996-01-01

This article focuses on the professional responsibilities that a lawyer owes to older clients. Specifically, this article proposes that when working with older clients, lawyers have a responsibility to ensure that their clients have the capacity to manage their own affairs and to ensure their clients' legal, financial, and personal interests are protected in case of sudden future incapacity. Furthermore, a lawyer working with older clients has a responsibility to remain cognizant of the realities of ageing without giving in to the falsities of senior citizen stereotypes. Through an integration of Therapeutic Jurisprudence and Preventive Law, a proactive, client-centered, four-stage framework for advancing therapeutic goals through preventive lawyering is developed. The framework is then applied to a model lawyer/client interaction typical of elder practice. The advantages and limitations of the four-stage framework are discussed.

This review proposes a more optimistic view of Alzheimer's disease (AD), in contrast to that contributed by the ageing of the population and the failure of potentially curative therapies (vaccines and others). Treatment failure is likely due to the fact that AD gestates in the brain for decades but manifests in old age. This review updates the concept of AD and presents the results of recent studies that show that primary prevention can reduce the incidence and delay the onset of the disease. Half of all cases of AD are potentially preventable through education, the control of cardiovascular risk factors, the promotion of healthy lifestyles and specific drug treatments. These approaches could substantially reduce the future incidence rate of this disease. Copyright © 2016 Elsevier España, S.L.U. and Sociedad Española de Medicina Interna (SEMI). All rights reserved.

Objective Non-communicable diseases (NCDs) are the biggest cause of death in Europe putting an unsustainable burden on already struggling health systems. Increases in obesity are a major cause of NCDs. This paper projects the future burden of coronary heart disease (CHD), stroke, type 2 diabetes and seven cancers by 2030 in 53 WHO European Region countries based on current and past body mass index (BMI) trends. It also tests the impact of obesity interventions on the future disease burden. Setting and participants Secondary data analysis of country-specific epidemiological data using a microsimulation modelling process. Interventions The effect of three hypothetical scenarios on the future burden of disease in 2030 was tested: baseline scenario, BMI trends go unchecked; intervention 1, population BMI decreases by 1%; intervention 2, BMI decreases by 5%. Primary and secondary outcome measures Quantifying the future burden of major NCDs and the impact of interventions on this future disease burden. Results By 2030 in the whole of the European region, the prevalence of diabetes, CHD and stroke and cancers was projected to reach an average of 3990, 4672 and 2046 cases/100 000, respectively. The highest prevalence of diabetes was predicted in Slovakia (10 870), CHD and stroke—in Greece (11 292) and cancers—in Finland (5615 cases/100 000). A 5% fall in population BMI was projected to significantly reduce cumulative incidence of diseases. The largest reduction in diabetes and CHD and stroke was observed in Slovakia (3054 and 3369 cases/100 000, respectively), and in cancers was predicted in Germany (331/100 000). Conclusions Modelling future disease trends is a useful tool for policymakers so that they can allocate resources effectively and implement policies to prevent NCDs. Future research will allow real policy interventions to be tested; however, better surveillance data on NCDs and their risk factors are essential for research and policy. PMID:25063459

In Indonesia, the Aceh earthquake and tsunami in 2004 killed 127,000 people and caused half a million injuries, while the Yogyakarta earthquake in 2006 caused 5,700 deaths and 37,000 injuries. Because disaster-affected areas are vulnerable to epidemic-prone diseases and tetanus is one such disease that is preventable, we systematically reviewed the literature related to tetanus outbreaks following previous two natural disasters in Indonesia. Based on our findings, recommendations for proper vaccination and education can be made for future countermeasures. Using specified keywords related to tetanus and disasters, relevant documents were screened from PubMed, the WHO website, and books. Reports offering limited data and those released before 2004 were excluded. In all, 16 publications were reviewed systematically. Results show that 106 cases of tetanus occurred in Aceh, with a case fatality ratio (CFR) of 18.9%; 71 cases occurred in Yogyakarta, with CFR of 36.6%. For both outbreaks, most patients had been wounded during scavenging or evacuation after the disaster occurred. Poor access to health care because of limited transportation or hospital facilities, and low vaccination coverage and lack of awareness of tetanus risk contributed to delayed treatment and case severity. Tetanus outbreaks after disasters are preventable by increasing vaccination coverage, improving wound care treatment, and establishing a regular surveillance system, in addition to good practices of disaster management and supportive care following national guidelines. Furthermore, health education for communities should be provided to raise awareness of tetanus risk reduction.

As the WHO verified that China reached the target of 1% prevalence of chronic hepatitis B infection among children targeted by universal hepatitis B immunization of newborns, the country considered new options for hepatitis B prevention and control. We reviewed hepatitis B surveillance in the broader context of viral hepatitis surveillance to propose recommendations to improve the system. We described surveillance for viral hepatitis in China with a specific focus on hepatitis B. We assessed critical attributes of the system, including data quality, predictive positive value and usefulness. While remarkable progress in hepatitis B immunization of infants and children has likely almost eliminated transmission in younger age groups, reported rates of hepatitis B increased steadily in China between 1990 and 2008, probably because of a failure to distinguish acute from chronic infections. Elements that prevented a clearer separation between acute and chronic cases included (1) missed opportunity to report cases accurately among clinicians, (2) low availability and use of tests to detect IgM against the hepatitis B core antigen (IgM anti-HBc) and (3) lack of systems to sort, manage and analyze surveillance data. To improve hepatitis B surveillance, China may consider (1) training clinicians to diagnose acute cases and to use IgM anti-HBc to confirm them, (2) improving access and use of validated IgM anti-HBc tests and (3) developing data management and analysis techniques that sort out acute from chronic cases.

Lymphangioleiomyomatosis (LAM) is a rare disease that occurs predominantly in females between the ages of 30 and 50 years and is clinically characterized by progressive dyspnoea on exertion, recurrent pneumothoraces, abdominal and thoracic lymphadenopathy, as well tumors-like angiomyolipomas and lymphangiomyomas. We present the case of a 42-year-old woman, who developed recurrent pneumothoraces and was subsequently diagnosed with LAM. Although pneumothorax is a common complication of the disease, its optimal approach to treatment and prevention remains unclear. Chemical or surgical pleurodesis are often performed in order to prevent recurrence, but may predispose to perioperative complications in the event of future lung transplantation. PMID:23390481

Brucellosis is an occupational disease affecting workers in butcher shops, the milking and dairy product industry, causing more than 500 000 new cases around the world. As a national statutory B infectious disease in China, morbidity of brucellosis is rapidly increasing in recent years. We report an occupational outbreak of brucellosis infection in a pharmaceutical factory. Exposure was a result of manual operation in the process line, close contact with sheep placentas, insufficient disinfection and repeated using of protective suits and infected by aerosol dissemination. Improved preventive methods, appropriate public health measures and spread of health education would be helpful to prevent the occupational outbreak of brucellosis in future. © 2016 Blackwell Verlag GmbH.

Overcoming Barriers to HIV Treatment Adherence: A Brief Cognitive Behavioral Intervention for HIV-Positive Adults on Antiretroviral Treatment

Maximizing HIV treatment adherence is critical in efforts to optimize health outcomes and to prevent further HIV transmission. The Balance Project intervention uses cognitive behavioral approaches to improve antiretroviral medication adherence through promoting adaptive coping with medication side effect and distress related to HIV. This 5-session intervention has been documented to prevent nonadherence among persons living with HIV who experience high levels of distress associated with their antiretroviral medication side effects. We describe the theoretical underpinnings of the intervention, provide details of the training and session protocols with a case example, and discuss implications for future applications of the intervention in both research and clinical settings.

The relationship between deliberate self-harm behavior, body dissatisfaction, and suicide in adolescents: current concepts

Deliberate self-harm (DSH) is a common though often hidden condition in children and adolescents that may result in suicide. This discussion covers several aspects of DSH including its prevalence, etiology, and management. The relationships of DSH to body dissatisfaction and suicide are specifically considered. Even though most cases of DSH do not end in overt suicide, DSH reflects that potential underlying psychological pathophysiology, and likelihood of eventual death from self-murder, cannot always be predicted or prevented. It is important to take all acts of DSH as serious, and to offer comprehensive management to prevent future acts of DSH and potential suicide. PMID:21811385

The regional and temporal variation in patterns of fruit and vegetable intake contributes to differences in the impact on gastric cancer burden across regions and over the years. We aimed to estimate the proportion and absolute number of gastric cancer cases that could have been prevented in 2012 with an increase in fruit and vegetable intake up to the levels defined by the Global Burden of Disease as the theoretical minimum-risk exposure distribution (300 and 400 g/d, respectively), as well as the corresponding figures expected for 2025. Preventable fractions (PF) were computed for 161 countries, using data on fruit and vegetable availability in 1997 and 2010 and published estimates of the magnitude of the association between fruit and vegetable intake and gastric cancer, assuming a time lag of approximately 15 years. Countries classified as very high Human Development Index (HDI) presented median PF in 2012 much lower than low-HDI countries for both fruits (3·0 v. 10·2%, P<0·001) and vegetables (6·0 v. 11·9%, P<0·001). For vegetables only, PF significantly decreased until 2025 in most settings; however, this corresponded to a reduction in the absolute number of preventable gastric cancer cases in less than half of the countries. Increasing fruit and vegetable intake would allow preventing a relatively high proportion of gastric cancer cases, mostly in developing countries. Although declines in PF are predicted in the near future, changes in order to achieve healthier lifestyles may be insufficient to overcome the load of demographic variation to further reduce the gastric cancer burden.

A national survey of candidates was conducted to identify motivations for pursuing psychoanalytic training, obstacles that prevent progression or completion, and candidates' ideas on how best to increase interest among potential trainees. In 2009-2010, 40 percent of candidates on the affiliate member e-mail list completed an anonymous web-based survey. Candidates strongly endorsed contact with a personal psychotherapist, psychoanalyst, or supervisor as the most important influence in discovering psychoanalysis and deciding to pursue training. They identified the total cost of analytic training as the greatest obstacle. This was followed by the cost of personal analysis, loss of income for low-fee cases, time away from family, and difficulty finding cases. To enhance training, local institutes should work to improve institute atmosphere and provide assistance with finding cases; national organizations should increase outreach activities and publicize psychoanalysis. Psychoanalytic institutes could recruit future candidates by working to increase personal contact with psychoanalysts, reducing the cost of training, improving institute atmosphere, assisting with case-finding, enhancing outreach activities, and widely publicizing psychoanalysis. Narrative comments from candidates and the implications of these findings regarding engagement of future trainees are discussed.

Despite the availability of effective antibacterial agents and vaccines, pneumococcal meningitis and sepsis are still associated with high mortality rates and a high risk of neurological sequelae. We describe the case of a 17-month-old boy vaccinated with heptavalent pneumococcal conjugate vaccine (PCV7) who developed bacterial meningitis complicated by subdural empyema and deafness caused by Streptococcus pneumoniae serotype 7F. The 7F strain is not contained in PCV7 (the only vaccine on the market at the time of the onset of meningitis) but is included in the new pediatric 13-valent PCV, which may therefore prevent cases such as this in the future.

We describe a rare case of synovial chondromatosis of the knee of a 2-year-old child. The diagnosis was based on the history, physical examination, and complementary examinations (radiography and magnetic resonance imaging). Anterior and posterior approaches were used for total synovectomy and resection of loose bodies. Physicians should keep this condition in mind, even in young children, because early identification prevents future secondary degenerative changes in the knee joint. As far as we know, this is the youngest child with synovial chondromatosis of the knee reported in the English-language literature.

This is a case of a male patient with a 27 year history of severe benign coital headache and associated symptoms. His condition was spontaneously relieved in the first trimester of his partner's pregnancy. This relief continued through the remainder of the pregnancy term, returning only after the birth of their child. The timing of the condition's relief and return of symptoms suggested progesterone was an intrinsic factor in this. Post-pregnancy the patient was able to prevent his attacks by taking oral norethisterone 5 mg. While writing this case the patient's partner became pregnant once more, resulting again in spontaneous relief of the patient's syndrome.

Suicide is a catastrophic event to both families and communities yet it is potentially preventable. This study aims to determine incidence and patterns of suicide in children and young adolescents in our region, raise awareness of this entity as a potentially preventable cause of death in this age group, and identify its possible associated risk factors. We retrospectively reviewed suicide cases presenting as sudden unexpected death in children and adolescents that underwent coronial post-mortems at our institution. This is the largest pathological review of completed suicide in children and young adolescents within a single institution in the United Kingdom. We identified 23 suicide cases during a 12 year period from 2003 to 2015, in which 18 cases (78%) were male and 5 cases (22%) were female. The age range was from 8 to 16 years (mean age 12.82 +/- 2.52 SD). With the exception of one case, all of the victims were Caucasian. The majority, 19 cases (81%), were found dead inside their place of residence, 15 of whom were discovered in their own bedrooms. Twenty-one cases (91%) died from neck compression due to hanging; 6 cases (26%) had used the cord of a dressing gown and 5 (22%) opted to use a belt as the ligature. Two cases (9%) that died from multiple-drug toxicity were female. In 7 cases (30.5%) there was evidence of self-harm and in 3 cases (13%) there was a history of previous suicide attempts. Petechial hemorrhages were found at autopsy in more than half of hanging victims and only three cases (14%) displayed dual distribution of post-mortem hypostasis (back and legs). Seven victims (30.5%) left some form of suicide message to family members and friends, 2 of which wrote the message on their arm. Parental separation, conflict with parents, and depression, were common amongst decedents prior to committing suicide. Substance abuse was uncommon in suicide within our cases. Valuable information is available from thorough review of suicide data in children and young adolescents from a single institution. Pathologists and clinicians can play crucial roles in identifying potential risk factors that may contribute to prevent future deaths.

New arrows in the quiver for targeting care management: high-risk versus high-opportunity case identification.

PubMed

Bernstein, Richard H

2007-01-01

"Care management" purposefully obscures the distinctions between disease and case management and stresses their common features: action in the present to prevent adverse future outcomes and costs. It includes identifying a high-need population by referrals, screening, or data analysis, assessing those likely to benefit from interventions, intervening, evaluating the intervention, and adjusting interventions when needed. High-risk individuals can be identified using at least 9 techniques, from referrals and questionnaires to retrospective claims analysis and predictive models. Other than referrals, software based on the risk-adjustment methodology that we have adapted can incorporate all these methodologies. Because the risk adjustment employs extensive case mix and severity adjustment, it provides care managers with 3 innovative ways to identify not only high-risk individuals but also high-opportunity cases.

West Nile Virus (WNV) is the causative agent of a vector-borne, zoonotic disease with a worldwide distribution. Recent expansion and introduction of WNV into new areas, including southern Europe, has been associated with severe disease in humans and equids, and has increased concerns regarding the need to prevent and control future WNV outbreaks. Since 2010, 524 confirmed human cases of the disease have been reported in Greece with greater than 10% mortality. Infected mosquitoes, wild birds, equids, and chickens have been detected and associated with human disease. The aim of our study was to establish a monitoring system with wild birds and reported human cases data using Geographical Information System (GIS). Potential distribution of WNV was modelled by combining wild bird serological surveillance data with environmental factors (e.g. elevation, slope, land use, vegetation density, temperature, precipitation indices, and population density). Local factors including areas of low altitude and proximity to water were important predictors of appearance of both human and wild bird cases (Odds Ratio = 1,001 95%CI = 0,723–1,386). Using GIS analysis, the identified risk factors were applied across Greece identifying the northern part of Greece (Macedonia, Thrace) western Greece and a number of Greek islands as being at highest risk of future outbreaks. The results of the analysis were evaluated and confirmed using the 161 reported human cases of the 2012 outbreak predicting correctly (Odds = 130/31 = 4,194 95%CI = 2,841–6,189) and more areas were identified for potential dispersion in the following years. Our approach verified that WNV risk can be modelled in a fast cost-effective way indicating high risk areas where prevention measures should be implemented in order to reduce the disease incidence.

Objectives: To examine the published evidence on interventions to prevent softball related injuries among adults, and to encourage more epidemiologic research as a foundation for future softball injury prevention efforts. Methods: The authors reviewed literature identified from six electronic databases for studies on softball related injuries. The search was limited to studies written in the English language, published between 1970 and 2002, and involving adult populations. Research was excluded that evaluated baseball ("hard ball") related injuries or was aimed at injury treatment. Identified studies were categorized by study design. Intervention/prevention papers were evaluated further and described in detail. Results: The search strategy identified 39 studies specifically related to softball. Most studies were case reports/case series (n = 13) or descriptive studies (n = 11); only four were analytic or intervention/prevention studies. Studies collected data in a variety of ways, often without denominator data to permit calculation of injury rates. Studies also did not differentiate between slow or fast pitch softball activities and most did not mention the type of softball that was used. Conclusions: Surprisingly few studies exist on interventions to reduce injuries during softball, one of the most popular recreational sports in the US. Of the existing literature, much attention has been on sliding related injuries, which comprise only a segment of softball injuries. Basic epidemiologic studies describing the nature, severity, and risk factors for softball injuries in a variety of populations are needed, followed by additional intervention evaluation studies aimed at modifiable risk factors.

To clarify the problems related to maternal deaths in Japan, including the diseases themselves, causes, treatments and the hospital or regional systems. Descriptive study. Maternal death registration system established by the Japan Association of Obstetricians and Gynecologists (JAOG). Women who died during pregnancy or within a year after delivery, from 2010 to 2014, throughout Japan (N=213). The preventability and problems in each maternal death. Maternal deaths were frequently caused by obstetric haemorrhage (23%), brain disease (16%), amniotic fluid embolism (12%), cardiovascular disease (8%) and pulmonary disease (8%). The Committee considered that it was impossible to prevent death in 51% of the cases, whereas they considered prevention in 26%, 15% and 7% of the cases to be slightly, moderately and highly possible, respectively. It was difficult to prevent maternal deaths due to amniotic fluid embolism and brain disease. In contrast, half of the deaths due to obstetric haemorrhage were considered preventable, because the peak duration between the initial symptoms and initial cardiopulmonary arrest was 1-3 h. A range of measures, including individual education and the construction of good relationships among regional hospitals, should be established in the near future, to improve primary care for patients with maternal haemorrhage and to save the lives of mothers in Japan.

2013-01-01

The Animal Health Act that replaces the Animal Disease Act, which is currently in force, creates a regulatory framework in order to not only, as has been the case so far, control animal diseases that had already broken out, but in order to already prevent in advance possible outbreaks of animal diseases by means of preventive measures. The instruments to this effect are described here. At European level, too, the idea of prevention is set to play a greater role in the future, with the draft EU legal instrument on animal health, that has to date only been discussed at Commission level, also contributing to a simplification and easier implementation by the persons subject to law by harmonising the currently fragmented Community law. It remains to be seen when the deliberations in the Council and European Parliament will begin.

Thinking about "Think Again" in Canada: assessing a social marketing HIV/AIDS prevention campaign.

Lombardo, Anthony P; Léger, Yves A

2007-06-01

The Canadian "Think Again" social marketing HIV/AIDS prevention campaign, adapted from an American effort, encourages gay men to rethink their assumptions about their partners' HIV statuses and the risks of unsafe sex with them. To improve future efforts, existing HIV/AIDS prevention initiatives require critical reflection. While a formal evaluation of this campaign has been carried out elsewhere, here we use the campaign as a social marketing case study to illustrate its strengths and weaknesses, as a learning tool for other campaigns. After describing the campaign and its key results, we assess how it utilized central tenets of the social marketing process, such as formative research and the marketing mix. We then speak to the importance of theoretical influence in campaign design and the need to account for social-contextual factors in safer sex decision making. We conclude with a summary of the lessons learned from the assessment of this campaign.

Partial rupture of the Achilles tendon during a simulated fire ground task: insights obtained from a case report for the prevention and reporting of musculoskeletal injury.

2013-04-01

In this case report an incumbent firefighter partially ruptured his right Achilles tendon during a study of the physical demands of firefighting. Kinematics and kinetics of the lower limbs and trunk were collected while the firefighter performed two simulated fire ground tasks. From this unexpected event, two insights were obtained that should be considered in all future injury prevention and reporting efforts. (i) Consider the full anatomical linkage--the right ankle and knee kinematics leading up to the onset of injury trial were comparable to all preceding repetitions. However, there was a notable difference in the left knee starting position before the initiation of movement of the 37th hose-advance trial. (ii) Consider the cumulative load--the task in question comprised forward and backward phases. A marked difference was observed in the frontal-plane ankle moment during the return phase of the trial preceding the injury. Additionally, the magnitude of the left side vertical ground reaction force was comparable across all trials, suggesting that loads experienced by the right limb were also similar. This would indicate that the tolerance of the Achilles tendon and not the magnitude of the loading was altered. The unfortunate injury captured in this work provides insight into the complexity of characterizing the pathways of injury. It is recommended that future injury prevention and reporting efforts consider individuals' physical demands (at work and in life) and document the nature of loading (i.e., frequency, duration, magnitude, type) when considering the mechanism for injury.

Since December 2013, West Africa has experienced the worst Ebola virus outbreak in recorded history. Of the 28,639 cases reported to the World Health Organization as of March 2016, nearly half (14,124) occurred in Sierra Leone. With a case fatality rate of approximately 40%, this outbreak has claimed the lives of 11,316 individuals. No FDA-approved vaccines or drugs are available to prevent or treat Ebola virus infection. Experimental vaccines and therapies are being developed; however, their safety and efficacy are still being evaluated. Therefore, there is an urgent need to develop control measures to prevent or limit future Ebola virus outbreaks.Previously, we developed a replication-defective Ebola virus that lacks the coding region for the essential viral transcription activator VP30 (Ebola ΔVP30 virus). Here, we evaluated the vaccine efficacy of Ebola ΔVP30 virus in a non-human primate model and describe our collaborative Ebola project in Sierra Leone.

2018-04-01

In September 2016, an imported case of measles in Edinburgh in a university student resulted in a further 17 confirmed cases during October and November 2016. All cases were genotype D8 and were associated with a virus strain most commonly seen in South East Asia. Twelve of the 18 cases were staff or students at a university in Edinburgh and 17 cases had incomplete or unknown measles mumps rubella (MMR) vaccination status. The public health response included mass follow-up of all identified contacts, widespread communications throughout universities in Edinburgh and prompt vaccination clinics at affected campuses. Imported cases of measles pose a significant risk to university student cohorts who may be undervaccinated, include a large number of international students and have a highly mobile population. Public health departments should work closely with universities to promote MMR uptake and put in place mass vaccination plans to prevent rapidly spreading measles outbreaks in higher educational settings in future.

Proteus mirabilis and its role in dacryocystitis.

PubMed

Borgman, Christopher J

2014-09-01

Dacryocystitis is a common inflammation of the lacrimal sac, usually from an underlying bacterial infection. Most cases can be attributed to common ocular flora such as Staphylococcus aureus or Streptococcus pneumoniae; however, uncommon bacterial causes such as Proteus mirabilis can still occur. P. mirabilis is a gram-negative bacillus that is found abundantly in people who have undergone long-term catheterization and is uncommonly found in or around the eyes except in people who have undergone long-term catheterization. Proteus species can cause conjunctivitis, canaliculitis, and dacryocystitis and have the ability to manifest into preseptal cellulitis; therefore, timely recognition and treatment are important to prevent potential further complications. An 84-year-old white man had several recurrences of acute dacryocystitis that had marginal improvement with empiric antibiotic treatment. Resultant culture of the ocular discharge revealed an uncommon bacterium, P. mirabilis. Successful dosing of oral antibiotics resolved the infection but ultimately the patient required an external dacryocystorhinostomy (DCR) procedure to maintain patency of the nasolacrimal lacrimal system and prevent recurrence. At 3 months after external DCR, the patient was symptom free with no recurrences. Dacryocystitis has a distinctive clinical presentation and is usually easily treated when appropriate oral antibiotics are directed at the underlying pathogen. In nonresponsive cases, culturing of the ocular discharge should be performed to identify the underlying pathogen. Cases of dacryocystitis caused by Proteus species are usually responsive to several standard antibiotics used orally in eye care; however, culturing and susceptibility testing can streamline the diagnostic and management sequence considerably in unclear or unresponsive cases. Typically, patients with dacryocystitis return to normal after appropriate treatment, but chronic recurrences and epiphora are potential sequelae. Patients should be educated that a DCR surgical procedure may be needed to prevent future recurrences in some cases.

Control of oral cancer in developing countries

PubMed Central

1984-01-01

Oral cancer is one of the 10 most common cancers in the world. In Bangladesh, India, Pakistan, and Sri Lanka it is the most common and accounts for about a third of all cancers. More than 100 000 new cases occur every year in south and south-east Asia, with poor prospects of survival. The importance of oral cancer as a public health priority is underscored by the fact that the suffering, disfigurement, and death it causes need not occur. The commonest cause of oral cancer—tobacco use—is well known and can be eliminated. For the oral cancer cases that do occur, detection at an early stage is possible, allowing simple inexpensive treatment, and resulting in long-term survival. Enough is already known about the disease and its prevention for action to be taken. With firm commitment, correct priorities, and concerted efforts by governments and individuals, strategies can be designed, programmes can be implemented, and the disease can be prevented. The economic saving in health care costs to a country, by itself, justifies these steps; the prevention of suffering and death of oral cancer victims makes them mandatory. This article reviews the current knowledge about the epidemiology, etiology, pathology, prevention, and treatment of oral cancer. It describes a strategy for controlling the disease, sets priorities, and recommends actions that governments and individuals can take. Finally, it identifies targets for future research.

Challenges and opportunities in the management of Clostridium difficile infection.

PubMed

DuPont, Herbert L

2014-11-01

Clostridium difficile infection (CDI) is increasing in all regions of the world where sought. There is no gold standard for diagnosis of CDI, with available tests having limitations. Prevention of CDI will be seen with antibiotic stewardship, improved disinfection of hospitals and nursing homes, chemo- and immuno-prophylaxis and next generation probiotics. The important therapeutic agents are oral vancomycin and fidaxomicin with metronidazole being used only in mild cases or when oral therapy cannot be given. Current therapy of CDI for 10 days is associated with high rate of recurrence that may be prevented by prolonging initial therapy. Future treatment strategies will focus on drugs that inhibit C. difficile, reduce toxin activity and inflammation in the gut, and improve colonic flora diversity.

Male circumcision and HIV prevention: current knowledge and future research directions.

PubMed

Bailey, R C; Plummer, F A; Moses, S

2001-11-01

Over the past decade, numerous epidemiological studies have reported a significant association between lack of male circumcision and risk for HIV infection, leading to recommendations for male circumcision to be added to the armamentarium of effective HIV prevention strategies. We review the epidemiological data from studies that have investigated this association, including ecological, cross-sectional/case-control, and prospective studies. We discuss problematic issues in interpreting the epidemiological data, including the presence of other sexually transmitted infections, age of circumcision, and potential confounders such as religion, cultural practices, and genital hygiene. In addition, we review studies of biological mechanisms by which the presence of the foreskin may increase HIV susceptibility, data on risks associated with the circumcision procedure, and available data on the acceptability and feasibility of introducing male circumcision in societies where it is traditionally not practised. Although the evidence in support of male circumcision as an effective HIV prevention measure is compelling, residual confounding in observational studies cannot be excluded. Taken together with concerns over the potential disinhibiting effect of male circumcision on risk behaviour, and safety of the circumcision procedure, randomised trials of male circumcision to prevent HIV infection are recommended. An individual's choice to undergo male circumcision or a community's decision to promote the practice should be made in the light of the best available scientific evidence. More knowledge is required to assist individuals and communities in making those decisions. We conclude with recommendations for future research.

The increasing roles of epigenetics in breast cancer: Implications for pathogenicity, biomarkers, prevention and treatment.

PubMed

Basse, Clémence; Arock, Michel

2015-12-15

Nowadays, the mechanisms governing the occurrence of cancer are thought to be the consequence not only of genetic defects but also of epigenetic modifications. Therefore, epigenetic has become a very attractive and increasingly investigated field of research in order to find new ways of prevention and treatment of neoplasia, and this is particularly the case for breast cancer (BC). Thus, this review will first develop the main known epigenetic modifications that can occur in cancer and then expose the future role that control of epigenetic modifications might play in prevention, prognostication, follow-up and treatment of BC. Indeed, epigenetic biomarkers found in peripheral blood might become new tools to detect BC, to define its prognostic and to predict its outcome, whereas epi-drugs might have an increasing potential of development in the next future. However, if DNA methyltransferase inhibitors and histone desacetylase inhibitors have shown encouraging results in BC, their action remains nonspecific. Thus, additional clinical studies are needed to evaluate more precisely the effects of these molecules, even if they have provided encouraging results in cotreatment and combined therapies. This review will also deal with the potential of RNA interference (RNAi) as epi-drugs. Finally, we will focus on the potential prevention of BC through epigenetic based on diet and we will particularly develop the possible place of isothiocyanates from cruciferous vegetables or of Genistein from soybean in a dietary program that might potentially reduce the risk of BC in large populations. © 2014 UICC.

2006-09-01

Peripherally inserted central venous catheter (PICC) lines have become a frequently used method of intravenous access for long-term administration of antibiotics, chemotherapy, and parenteral nutrition. Catheter-related complications involving the arterial tree are rare. We report a case of a 25-year-old woman with a history of difficult PICC line placement that presented with an arteriovenous fistula in the left arm. Duplex ultrasound confirmed the diagnosis of a brachial artery-to-brachial vein arteriovenous fistula (AVF), and the patient underwent surgical repair. To our knowledge, this is the first reported case of an AVF resulting from PICC line placement. Correction of AVF is indicated to alleviate symptoms as well as to prevent future complications.

Ocular Injury in Cosmetic Laser Treatments of the Face.

Huang, Amy; Phillips, Arianna; Adar, Tony; Hui, Andrea

2018-02-01

BACKGROUND: The eye is a vulnerable and commonly injured organ in cosmetic laser procedures of the face. Treatment of the eyelids and periorbital areas increases this risk, especially when ocular protection devices are not used or are removed during the procedure. A study has shown that injury from laser epilation of the periocular areas is one of the most common causes of litigation in cutaneous laser surgery. OBJECTIVE: The goal of this review is to determine the causes of ocular injury in cosmetic laser procedures and derive lessons on critical safety elements to prevent future injury. METHODS: We conducted a review of the current literature through a PubMed search on case reports of ocular injury in cosmetic laser treatments of the face. Twenty-one cases are examined. RESULTS: In more than 62 percent of cases, ocular protection was not used or protection was used but removed during the procedure to treat areas close to the eye. However, despite the proper use of intraocular corneal shields and wavelength-specific goggles, accidents occurred in 33 percent of cases. CONCLUSION: Ocular protection devices are essential to prevent most cases of laser-induced eye injury. Use of high fluence and long wavelength lasers increases the risk of ocular injury due to deeper penetration of the organ by radiation. Inadequate cooling between pulses also predisposes to injury by cosmetic lasers.

Medical disputes between physicians and patients can occur in non-negligent circumstances and may even result in compensation. We reviewed medical dispute cases to investigate the impact of miscommunication, especially in non-negligent situations. Systematic review of medical dispute records was done to identify the presence of the adverse events, the type of medical error, preventability, the perception of miscommunication by patients and the amount of compensation. The study was performed in Kyoto, Japan. We analyzed 155 medical dispute cases. We compared (i) frequency of miscommunication cases between negligent and non-negligent cases, and (ii) proportions of positive compensation between non-miscommunication and miscommunication cases stratified according to the existence of negligence. Multivariate logistic analysis was conducted to assess the independent factors related to positive compensation. Approximately 40% of the medical disputes (59/155) did not involve medical error (i.e. non-negligent). In the non-negligent cases, 64.4% (38/59) involved miscommunication, whereas in dispute cases with errors, 21.9% (21/96) involved miscommunications. (P

[The Herceptin® case : A case of falsification of medicinal products to a greater extent].

PubMed

Streit, Renz

2017-11-01

Falsified medicines are a raising problem for the German drug market. The complex distribution channels across the European market facilitates the introduction of falsified and stolen medicines into the legal supply chain and may pose a risk for patients. The "Herceptin® case" from 2014 of falsified medicines of Italian origin demonstrates how complex distribution systems have been misused by criminal organizations in order to introduce stolen and thus falsified medicines via the parallel trade into the market, and which measures the authorities and the parallel-traders in the national and European network have taken to ensure patient safety. Falsified medicines will continue to be a problem in the future, so new monitoring systems have to be established and effectively used for prevention. The introduction of the EU-wide serialisation system in February 2019 is therefore intended to identify falsified drugs and to prevent the further trade as well as the expenditure to the patient. Furthermore, the maintenance and intensification of the cooperation between all EU authorities involved remains indispensable to close gateways in the distribution system for falsified medicines and to minimise the risk to the population.

Cross-Border Cholera Outbreaks in Sub-Saharan Africa, the Mystery behind the Silent Illness: What Needs to Be Done?

Mwesawina, Maurice; Baluku, Yosia; Kanyanda, Setiala S. E.; Orach, Christopher Garimoi

2016-01-01

Introduction Cross-border cholera outbreaks are a major public health problem in Sub-Saharan Africa contributing to the high annual reported cholera cases and deaths. These outbreaks affect all categories of people and are challenging to prevent and control. This article describes lessons learnt during the cross-border cholera outbreak control in Eastern and Southern Africa sub-regions using the case of Uganda-DRC and Malawi-Mozambique borders and makes recommendations for future outbreak prevention and control. Materials and Methods We reviewed weekly surveillance data, outbreak response reports and documented experiences on the management of the most recent cross-border cholera outbreaks in Eastern and Southern Africa sub-regions, namely in Uganda and Malawi respectively. Uganda-Democratic Republic of Congo and Malawi-Mozambique borders were selected because the countries sharing these borders reported high cholera disease burden to WHO. Results A total of 603 cross-border cholera cases with 5 deaths were recorded in Malawi and Uganda in 2015. Uganda recorded 118 cases with 2 deaths and CFR of 1.7%. The under-fives and school going children were the most affected age groups contributing 24.2% and 36.4% of all patients seen along Malawi-Mozambique and Uganda-DRC borders, respectively. These outbreaks lasted for over 3 months and spread to new areas leading to 60 cases with 3 deaths, CRF of 5%, and 102 cases 0 deaths in Malawi and Uganda, respectively. Factors contributing to these outbreaks were: poor sanitation and hygiene, use of contaminated water, floods and rampant cross-border movements. The outbreak control efforts mainly involved unilateral measures implemented by only one of the affected countries. Conclusions Cross-border cholera outbreaks contribute to the high annual reported cholera burden in Sub-Saharan Africa yet they remain silent, marginalized and poorly identified by cholera actors (governments and international agencies). The under-fives and the school going children were the most affected age groups. To successfully prevent and control these outbreaks, guidelines and strategies should be reviewed to assign clear roles and responsibilities to cholera actors on collaboration, prevention, detection, monitoring and control of these epidemics.

Preventative Disease Management and Grower Decision Making: A Case Study of California Wine-Grape Growers.

Hillis, Vicken; Lubell, Mark; Kaplan, Jonathan; Baumgartner, Kendra

2017-06-01

Preventative disease management is challenging to farmers because it requires paying immediate costs in the hopes of returning uncertain future benefits. Understanding farmer decision making about prevention has the potential to reduce disease incidence and minimize the need for more costly postinfection practices. For example, the grapevine trunk-disease complex (esca, Botryosphaeria dieback, Eutypa dieback, and Phomopsis dieback) significantly affects vineyard productivity and longevity. Given the chronic nature of the infections and inability to eradicate the fungal pathogens, the preventative practices of delayed pruning, applications of pruning-wound protectants, and double pruning (also known as prepruning) are the most effective means of management. We surveyed wine-grape growers in six regions of California on their use of these three practices. In spite of acknowledging the yield impacts of trunk diseases, a substantial number of respondents either choose not to use preventative practices or incorrectly adopted them in mature vineyards, too late in the disease cycle to be effective. Growers with more negative perceptions of cost efficacy were less likely to adopt preventative practices or were more likely to time adoption incorrectly in mature vineyards. In general, preventative management may require strong intervention in the form of policy or extension to motivate behavioral change.

Past, Current, and Future Incidence Rates and Burden of Metastatic Prostate Cancer in the United States.

2017-11-18

Metastatic prostate cancer (PCA) remains a highly lethal malignancy in the USA. As prostate-specific antigen testing declines nationally, detailed assessment of current age- and race-specific incidence trends and quantitative forecasts are needed. To evaluate the current trends of metastatic PCA by age and race, and forecast the number of new cases (annual burden) and future trends. We derived incidence data for men aged ≥45 yr who were diagnosed with metastatic PCA from the population-based Surveillance, Epidemiology, and End Results registries. We examined the current trends of metastatic PCA from 2004 to 2014, and forecast the annual burden and incidence rates by age and race for 2015-2025, using age-period-cohort models and population projections. We also examined alternative forecasts (2012-2025) using trends prior to the revised screening guidelines issued in 2012. Metastatic PCA, steadily declining from 2004 to 2007 by 1.45%/yr, began to increase by 0.58%/yr after 2008, which accelerated to 2.74%/yr following the 2012 United States Preventive Services Task Force recommendations-a pattern that was magnified among men aged ≤69 yr and white men. Forecasts project the incidence to increase by 1.03%/yr through 2025, with men aged 45-54 yr (2.29%/yr) and 55-69 yr (1.53%/yr) increasing more rapidly. Meanwhile, the annual burden is expected to increase 42% by 2025. Our forecasts estimated an additional 15 891 metastatic cases from 2015 to 2025 compared with alternative forecasts using trends prior to 2012. The recent uptick in metastatic PCA rates has resulted in forecasts that project increasing rates through 2025, particularly among men aged ≤69 yr. Moreover, racial disparities are expected to persist and the annual burden will increase considerably. The impact of the prior and current PCA screening recommendations on metastatic PCA rates requires continued examination. In this report, we assessed how the incidence of metastatic prostate cancer has changed over recent years, and forecast future incidence trends and the number of new cases expected each year. We found that the incidence of metastatic prostate cancer has been increasing more rapidly since 2012, resulting in a rise in both future incidence and the number of new cases by 2025. Future incidence rates and the number of new cases were reduced in alternative forecasts using data prior to the 2012 United States Preventive Services Task Force (USPSTF) recommendations against prostate-specific antigen (PSA) testing for prostate cancer. There is a need for additional research that examines whether national declines in PSA testing contributed to increases in rates of metastatic disease. The incidence of metastatic disease in black men is still expected to occur at considerably higher rates compared with that in white men. Published by Elsevier B.V.

Therapy of stress (takotsubo) cardiomyopathy: present shortcomings and future perspectives.

Several therapeutic options are available for the treatment of the acute phase of stress cardiomyopathy, pharmacological (β-blockers, diuretics, anticoagulants, antiarrhythmics, noncatecholamine inotropics [levosimendan]), and nonpharmacological (intra-aortic balloon pumping, extracorporeal membrane oxygenation), according to the wide possible clinical presentation and course of the disease. However, there is a gap in evidence, and very few data come from randomized and adequately powered studies. Some evidence supports the use of β-blockers, in particular with a short half-life, in the case of left ventricular outflow tract obstruction, and angiotensin-converting enzyme inhibitors in secondary prevention. Future perspectives include the study of genetic basis of stress cardiomyopathy, role of miRNA and neurovegetative modulation. Randomized studies, however, are surely warranted.

Benign coital headache relieved by partner’s pregnancies with implications for future treatment

2010-01-01

This is a case of a male patient with a 27 year history of severe benign coital headache and associated symptoms. His condition was spontaneously relieved in the first trimester of his partner’s pregnancy. This relief continued through the remainder of the pregnancy term, returning only after the birth of their child. The timing of the condition’s relief and return of symptoms suggested progesterone was an intrinsic factor in this. Post-pregnancy the patient was able to prevent his attacks by taking oral norethisterone 5 mg. While writing this case the patient’s partner became pregnant once more, resulting again in spontaneous relief of the patient’s syndrome. PMID:22315637

Objectives. We describe an emerging public health concern regarding silicosis in the fast-growing highway repair industry. Methods. We examined highway construction trends, silicosis surveillance case data, and environmental exposure data to evaluate the risk of silicosis among highway repair workers. We reviewed silicosis case data from the construction industry in 3 states that have silicosis registries, and we conducted environmental monitoring for silica at highway repair work sites. Results. Our findings indicate that a large population of highway workers is at risk of developing silicosis from exposure to crystalline silica. Conclusions. Exposure control methods, medical screenings, protective health standards, and safety-related contract language are necessary for preventing future occupational disease problems among highway repair workers.

Neonaticide is a rare form of homicide. It is generally classed as manslaughter but differs from other forms of homicide in many respects. The factors favouring its occurrence and the legal position of neonaticide in Germany are discussed. The case is presented of a mother who committed five neonaticides within 8 years. While she was a caring mother for her two oldest children, she killed the five subsequent offspring immediately after giving birth. In the scarce literature on neonaticides, a case of multiple offending is particularly rare. Similarities to, and differences from, other cases of neonaticide in the literature are considered. The psychodynamic context of the offences is examined in order to identify contributing features which could be used to help prevent future occurrences.

A methodological framework to assess the socio-economic impact of underground quarries: A case study from Belgian Limburg.

Sergeant, A; Poesen, J; Duchateau, P; Vranken, L

2016-01-15

This study developed a methodology to assess the socio-economic impact of the presence and collapse of underground limestone quarries. For this we rely on case study evidence from Riemst, a village located in Eastern Belgium and use both secondary and primary data sources. A sinkhole inventory as well as data about the prevention costs provided by the municipality was used. To estimate the recreational values of the quarries, visitor data was obtained from the tourist office of Riemst. Next, two surveys were conducted among inhabitants and four real estate agents and one notary. The direct and indirect damages were assessed using respectively the repair cost and production and real estate value losses. The total yearly direct and indirect damage equals €415000 (±€85000) and more than half of it can be attributed to the depreciation of real estate (€230000). The quarries have recreational, cultural-historical and ecological values and thus generate societal benefits. The yearly recreational value was at least €613000 in 2012 values. The ecological and cultural-historical values augment to €180000 per year (in 2012 values). Further, our study indicates that the gains from filling up the quarries below the houses located above an underground limestone quarry outweigh the costs in the case study area. The net gain from filling up the underground quarry ranges €38700 to €101700 per house. This is only the lower bound of the net gain from filling up these underground quarries since preventive filling makes future collapses less likely so that future direct repair costs will be most likely smaller.

Conley, Colleen S; Durlak, Joseph A; Shapiro, Jenna B; Kirsch, Alexandra C; Zahniser, Evan

2016-08-01

The uses of technology-delivered mental health treatment options, such as interventions delivered via computer, smart phone, or other communication or information devices, as opposed to primarily face-to-face interventions, are proliferating. However, the literature is unclear about their effectiveness as preventive interventions for higher education students, a population for whom technology-delivered interventions (TDIs) might be particularly fitting and beneficial. This meta-analytic review examines technological mental health prevention programs targeting higher education students either without any presenting problems (universal prevention) or with mild to moderate subclinical problems (indicated prevention). A systematic literature search identified 22 universal and 26 indicated controlled interventions, both published and unpublished, involving 4763 college, graduate, or professional students. As hypothesized, the overall mean effect sizes (ESs) for both universal (0.19) and indicated interventions (0.37) were statistically significant and differed significantly from each other favoring indicated interventions. Skill-training interventions, both universal (0.21) and indicated (0.31), were significant, whereas non-skill-training interventions were only significant among indicated (0.25) programs. For indicated interventions, better outcomes were obtained in those cases in which participants had access to support during the course of the intervention, either in person or through technology (e.g., email, online contact). The positive findings for both universal and indicated prevention are qualified by limitations of the current literature. To improve experimental rigor, future research should provide detailed information on the level of achieved implementation, describe participant characteristics and intervention content, explore the impact of potential moderators and mechanisms of success, collect post-intervention and follow-up data regardless of intervention completion, and use analysis strategies that allow for inclusion of cases with partially missing data.

[Directions for future development of preventive medicine in Korea].

PubMed

Kim, Joon Youn

2006-05-01

It is the actual state of the medical society in our country that many graduates of medical schools want to be clinicians, and accordingly Korea's medical situation is relatively too focused on curative medicine. However, this situation is changing due to several factors including a growing number of doctors, inappropriate regulations for medical fees, changes in social status of doctors themselves, and excessive competition between doctors. Furthermore, we expect more advances in medical field of Korea since Korean government started to attach great importance to sciences and produced policies to support sciences, and as a result, more and more interest and effort in the fields of basic research including preventive medicine is being attached especially by young doctors as compared against the past. However, decline of clinical medicine fields doesn't always mean bright future for the field of preventive medicine. True future is possible and meaningful only when we prepare for it by ourselves. In other words, as the promising future is closed to one who spares no effort, we shouldn't fear to oppose unknown challenges and simultaneously need to support colleagues who bear such a positive mind. It is the most important thing for our preventive medicine doctors to evaluate the past and the present of preventive medicine and to foster a prospective mind to prepare for the future of preventive medicine. I set forth my several views according to directions for the development of preventive medicine which we already discussed and publicized in the academic circle of preventive medicine. Those directions are recommen dation of clinical preventive medicine, promotion of preventive medicine specialty, fostering the next generations, improving the quality of genetic epidemiologic study, participation in control of environmental pollution and food safety, contribution to chronic disease control, and preparation to role in medical services for unified Korea.

Stakeholders' perceptions of programme sustainability: findings from a community-based fall prevention programme.

Hanson, H M; Salmoni, A W

2011-08-01

Sustainability of health promotion and injury prevention programmes is a goal of practitioners and an increasingly common requirement of funding bodies. However, less is known about the views held by individual stakeholders involved in such programmes regarding their perceptions of facilitators and barriers to achieving sustainability. This paper aims to share the perceptions of programme sustainability held by key stakeholders involved in a community-based fall prevention programme in three Ontario demonstration communities in Canada. A qualitative case study research design. A holistic multiple case study method was employed. In total, 45 stakeholders involved in various aspects of the project participated from three demonstration sites. Stakeholders' perceptions were gathered on the individual actions they took in an effort to promote sustainability, and the barriers they perceived as preventing or limiting sustainability. Stakeholders reported taking a number of actions to aid programme sustainability, with some actions deemed to be more functional in aiding sustainability than others. Common actions reported by stakeholders included partnership formation, networking and increasing community capacity. Stakeholders also perceived a number of barriers to achieving sustainability, including insufficient human and financial resources, lack of co-ordination and buy-in, heavy reliance on volunteers and an inability to mobilize physicians. Stakeholders' perceptions of sustainability were used to develop recommendations for sustainability for both communities and funding bodies. The views and experiences shared by the stakeholders in this project can serve as lessons learnt to aid in the sustainability of other health promotion and injury prevention programmes in the future.

Adverse events occur in up to 10% of obstetric cases, and up to one half of these could be prevented. Case reviews and root cause analysis using a structured tool may help health care providers to learn from adverse events and to identify trends and recurring systems issues. We sought to establish the reliability of a root cause analysis computer application called Standardized Clinical Outcome Review (SCOR). We designed a mixed methods study to evaluate the effectiveness of the tool. We conducted qualitative content analysis of five charts reviewed by both the traditional obstetric quality assurance methods and the SCOR tool. We also determined inter-rater reliability by having four health care providers review the same five cases using the SCOR tool. The comparative qualitative review revealed that the traditional quality assurance case review process used inconsistent language and made serious, personalized recommendations for those involved in the case. In contrast, the SCOR review provided a consistent format for recommendations, a list of action points, and highlighted systems issues. The mean percentage agreement between the four reviewers for the five cases was 75%. The different health care providers completed data entry and assessment of the case in a similar way. Missing data from the chart and poor wording of questions were identified as issues affecting percentage agreement. The SCOR tool provides a standardized, objective, obstetric-specific tool for root cause analysis that may improve identification of risk factors and dissemination of action plans to prevent future events.

Gestational diabetes mellitus: postpartum opportunities for the diagnosis and prevention of type 2 diabetes mellitus

2015-01-01

SUMMARY Gestational diabetes mellitus (GDM) affects approximately 4% of all pregnant women in the US and represents 90% of all cases of diabetes mellitus diagnosed during pregnancy. In addition to the adverse pregnancy outcomes associated with this complication, a history of GDM predisposes women to the future development of type 2 diabetes mellitus (T2DM). Incidence rates of GDM are increasing in the US. As a consequence, a growing number of women are now at increased risk for T2DM. Opportunities to diagnose and prevent T2DM in women with a history of GDM include early diagnosis by postpartum screening and implementation of diabetes prevention measures. In this Review, we discuss current guidelines for postpartum screening, how they might be implemented, and who should take responsibility for screening individuals at risk of T2DM. In addition, we describe measures to prevent the onset of T2DM in women with a history of GDM, focusing on lifestyle modifications, such as diet and breast-feeding. PMID:18779843

The 2007 epidemic of equine influenza in Australia provided an opportunity to investigate the effectiveness of on-farm biosecurity measures in preventing the spread of a novel pathogen in a largely naive population. We conducted a case-control study of 200 horse premises from highly affected regions of the state of New South Wales (NSW), to investigate risk factors for the spread of equine influenza onto horse premises, specifically, non-compliance with biosecurity measures recommended to horse owners by the relevant animal health authority, the NSW Department of Primary Industries. The study was restricted to cases occurring during the first seven weeks of the epidemic, a period prior to vaccination and the relaxation of some movement restrictions. Case and control premises were selected from a laboratory testing dataset and interviews were conducted with horse owners and managers on premises between July and November 2009. The proximity of premises to the nearest infected premises was the factor most strongly associated with case status. Case premises were more likely than control premises to be within 5 km and beyond 10 km of an infected premises. Having a footbath in place on the premises before any horses were infected was associated with a nearly four-fold reduction in odds of infection (odds ratio=0.27; 95% confidence interval: 0.09, 0.83). This protective association may have reflected overall premises biosecurity standards related to the fomite transmission of equine influenza. Compliance with certain on-farm biosecurity practices seemingly prevented horses on premises in high risk areas being infected with equine influenza during the 2007 outbreak in Australia. In future outbreaks, in addition to broader disease control measures, on-farm biosecurity practices should be adopted by horse owners and managers to prevent equine influenza spread.

To summarize the historical events and drivers underlying public policy for the prevention and control of healthcare-associated infections in Brazil and in the United Kingdom. In doing so, the article aims to identify lessons and recommendations for future development of public policy. The analysis is based on a historical overview of national healthcare-associated infections programs taken from previously published sources. Findings highlight how the development of healthcare-associated infections prevention and control policies followed similar trajectories in Brazil and the United Kingdom. This can be conceptualized around four sequential phases: Formation, Consolidation, Standardization, and Monitoring and Evaluation. However, while we identified similar phases of development in Brazil and the United Kingdom, it can be seen that the former entered each stage around 20 years after the latter.

Prevention of decompression sickness during extravehicular activity in space: a review.

PubMed

Tokumaru, O

1997-12-01

Extended and more frequent extravehicular activity (EVA) is planned in NASA's future space programs. The more EVAs are conducted, the higher the incidence of decompression sickness (DCS) that is anticipated. Since Japan is also promoting the Space Station Freedom project with NASA, DCS during EVA will be an inevitable complication. The author reviewed the pathophysiology of DCS and detailed four possible ways of preventing decompression sickness during EVA in space: (1) higher pressure suit technology; (2) preoxygenation/prebreathing; (3) staged decompression; and (4) habitat or vehicle pressurization. Among these measures, development of zero-prebreathe higher pressure suit technology seems most ideal, but because of economic and technical reasons and in cases of emergency, other methods must also be improved. Unsolved problems like repeated decompression or oxygen toxicity were also listed.

Falls prevention focused medication review by a pharmacist in an acute hospital: implications for future practice.

Patients at risk of falling are regularly prescribed medicines which increase falls risk. Medication review is a widely advocated risk reduction strategy. The objectives of this descriptive study were to determine the number and types of falls risk medicines suitable for intervention, and to develop guidance to optimise the effectiveness of future medication related falls prevention initiatives. An Irish acute teaching hospital and tertiary referral centre. 50 hospital in-patients at risk of falls underwent medication review focused on falls prevention by a pharmacist. Falls risk medicines were identified, and reviewed. If scope to discontinue, dose reduce or switch to a safer alternative was identified by the pharmacist, the suggested medication changes were communicated to the patient's care team. Identification of the classes of falls risk medicines and types of prescriptions with greatest potential for intervention. Results The mean number of falls risk medicines prescribed to each patient was 4.8 (± 2.8) and the total number prescribed to the 50 patients was 238. Following medication review, the pharmacist identified 48 (20 %) as suitable for intervention. Consequently, 34 medication changes (70.8 %) were implemented. Four medication classes accounted for over 80 % of medication changes. These were anti-emetics, opioid analgesics, anti-cholinergic agents acting on the bladder and benzodiazepines/hypnotics. Intervention was statistically significantly more likely to be possible in the case of p.r.n. medicines compared to regular medicines (p < 0.001, Chi square test). Medication reviews focused on falls prevention took an average of 23.5 min per patient to complete. Medication reviews focused on falls prevention involve striking a balance between minimising medicines associated with falls and effectively treating medical conditions. We found only 20 % of falls risk medicines were suitable for change, and reviews were time consuming and resource intensive. However, targeting four medication classes, and being particularly alert to the potential to discontinue 'as required' medicines, has the potential to achieve most of the benefits of more comprehensive reviews. This information will guide the development of future falls risk medicine review initiatives in our hospital, increasing their feasibility in the acute hospital setting.

Homicide followed by the suicide of the murderer is a relatively rare lethal incident in which an individual kills another person and subsequently dies by suicide. Cases involving a homicide and a suicide in which death examinations and autopsies were performed at The Konya Branch of the Forensic Medicine Council between 2000 and 2007 were retrospectively investigated. During the studied time period, there were 10 homicide-suicide cases identified with 10 perpetrators killing 12 victims. Nine of the perpetrators were men and eight of the victims were women. The precipitating motive was an impending divorce in four of the cases. Two perpetrators were described as severely depressed, one had a diagnosis of antisocial personality disorder, and one was a pedophile who had reactive depression. Firearms were used in eight of the homicide cases and seven of the suicides. Constricting the use of firearms may reduce/prevent future homicide-suicide cases, as it is the most commonly used method to carry out homicide-suicides.

2012-03-01

To describe the cultural dimensions that might help or hinder dengue prevention in two Mexican localities having different experiences related to this disease. A cognitive-cultural anthropological study was conducted involving the participation of 160 adults selected through purposeful sampling. The techniques of free lists and pile-sorting were used for investigating terms associated with the concept "dengue." A consensus analysis was carried out by the factoring of principal components, hierarchical cluster analysis, and multidimensional scaling. Greater consensus was observed among participants from the population having more historical experience with dengue-Santiago Ixcuintla, Nayarit-as well as more structured cultural and complex dimensions than in Guadalajara. In the latter case, participants showed a more fragmented conception of dengue, with insufficient information on its symptoms, mechanisms of transmission, and vector reservoirs. Three cultural dimensions were identified as hindering dengue prevention: confusing and insufficient information, placing responsibility for prevention on other people or on public agencies, and excessive confidence in fumigation as a preventive measure. These obstacles will need to be taken into account in the design and implementation of future prevention campaigns, disseminating information that explains the risks of fumigation and the importance of citizens and authorities jointly participating in the search for a comprehensive and sustainable solution to the dengue problem.

Selected studies with specific relevance to substance abuse prevention interventions with Hispanic youth and families were examined to identify prior findings and emerging issues that may guide the design of future substance abuse prevention intervention research and its implementation with Hispanic populations. The origins of prevention research and role of risk and protective factors are examined, including culturally-specific risk and protective factors for Hispanic populations. Correlational studies, non-experimental interventions, and randomized controlled trials were examined for the period of 1974-2003. The literature search yielded 15 articles selected for this review that exhibited adequate methodological rigor. An added search for more recent studies identified three additional articles, for a total of 18 prevention intervention articles that were reviewed. Theoretical and methodological issues and recommendations are presented for future research aimed at improving the efficacy and effectiveness of future prevention intervention studies and their cultural relevance for Hispanic populations.

Role of healthcare workers in early epidemic spread of Ebola: policy implications of prophylactic compared to reactive vaccination policy in outbreak prevention and control.

Ebola causes severe illness in humans and has epidemic potential. How to deploy vaccines most effectively is a central policy question since different strategies have implications for ideal vaccine profile. More than one vaccine may be needed. A vaccine optimised for prophylactic vaccination in high-risk areas but when the virus is not actively circulating should be safe, well tolerated, and provide long-lasting protection; a two- or three-dose strategy would be realistic. Conversely, a reactive vaccine deployed in an outbreak context for ring-vaccination strategies should have rapid onset of protection with one dose, but longevity of protection is less important. In initial cases, before an outbreak is recognised, healthcare workers (HCWs) are at particular risk of acquiring and transmitting infection, thus potentially augmenting early epidemics. We hypothesise that many early outbreak cases could be averted, or epidemics aborted, by prophylactic vaccination of HCWs. This paper explores the potential impact of prophylactic versus reactive vaccination strategies of HCWs in preventing early epidemic transmissions. To do this, we use the limited data available from Ebola epidemics (current and historic) to reconstruct transmission trees and illustrate the theoretical impact of these vaccination strategies. Our data suggest a substantial potential benefit of prophylactic versus reactive vaccination of HCWs in preventing early transmissions. We estimate that prophylactic vaccination with a coverage >99% and theoretical 100% efficacy could avert nearly two-thirds of cases studied; 75% coverage would still confer clear benefit (40% cases averted), but reactive vaccination would be of less value in the early epidemic. A prophylactic vaccination campaign for front-line HCWs is not a trivial undertaking; whether to prioritise long-lasting vaccines and provide prophylaxis to HCWs is a live policy question. Prophylactic vaccination is likely to have a greater impact on the mitigation of future epidemics than reactive strategies and, in some cases, might prevent them. However, in a confirmed outbreak, reactive vaccination would be an essential humanitarian priority. The value of HCW Ebola vaccination is often only seen in terms of personal protection of the HCW workforce. A prophylactic vaccination strategy is likely to bring substantial additional benefit by preventing early transmission and might abort some epidemics. This has implications both for policy and for the optimum product profile for vaccines currently in development.

Mosquito-borne diseases are climate sensitive and there has been increasing concern over the impact of climate change on future disease risk. This paper projected the potential future risk of Barmah Forest virus (BFV) disease under climate change scenarios in Queensland, Australia. We obtained data on notified BFV cases, climate (maximum and minimum temperature and rainfall), socio-economic and tidal conditions for current period 2000-2008 for coastal regions in Queensland. Grid-data on future climate projections for 2025, 2050 and 2100 were also obtained. Logistic regression models were built to forecast the otential risk of BFV disease distribution under existing climatic, socio-economic and tidal conditions. The model was applied to estimate the potential geographic distribution of BFV outbreaks under climate change scenarios. The predictive model had good model accuracy, sensitivity and specificity. Maps on potential risk of future BFV disease indicated that disease would vary significantly across coastal regions in Queensland by 2100 due to marked differences in future rainfall and temperature projections. We conclude that the results of this study demonstrate that the future risk of BFV disease would vary across coastal regions in Queensland. These results may be helpful for public health decision making towards developing effective risk management strategies for BFV disease control and prevention programs in Queensland.

Eating Disorders (EDs) are serious psychiatric illnesses marked by psychiatric comorbidity, medical complications, and functional impairment. Research indicates that female athletes are often at greater risk for developing ED pathology versus non-athlete females. The Female Athlete Body (FAB) study is a three-site, randomized controlled trial (RCT) designed to assess the efficacy of a behavioral ED prevention program for female collegiate athletes when implemented by community providers. This paper describes the design, intervention, and participant baseline characteristics. Future papers will discuss outcomes. Female collegiate athletes (N=481) aged 17-21 were randomized by site, team, and sport type to either FAB or a waitlist control group. FAB consisted of three sessions (1.3h each) of a behavioral ED prevention program. Assessments were conducted at baseline (pre-intervention), post-intervention (3weeks), and six-, 12-, and 18-month follow-ups. This study achieved 96% (N=481) of target recruitment (N=500). Few group differences emerged at baseline. Total sample analyses revealed moderately low baseline instances of ED symptoms and clinical cases. Health risks associated with EDs necessitate interventions for female athletes. The FAB study is the largest existing RCT for female athletes aimed at both reduction of ED risk factors and ED prevention. The methods presented and population recruited for this study represent an ideal intervention for assessing the effects of FAB on both the aforementioned outcomes. We anticipate that findings of this study (reported in future papers) will make a significant contribution to the ED risk factor reduction and prevention literature. Copyright © 2017 Elsevier Inc.

Measuring the impact of HIV / AIDS on Africa's commercial sector (a Kenyan case study).

Forsythe, S; Roberts, M; Wongombe, J; Gakuru, O

1994-01-01

Two rounds of interviews were conducted with managers of companies in Kenya to assess the impact of HIV/AIDS and to project how this impact will change in the future. In the first round, managers of 16 companies provided information on their views about the impact of AIDS and their assessment of current prevention programs and future needs. 5 of these consented to more detailed analysis. All of the managers had direct experience with a worker with HIV/AIDS, but few felt the disease had any current impact (although all believed that an impact was inevitable in the future). This analysis assessed additional costs (health care, burial fees, and recruitment) and decreased revenues (loss in production time). Projections based on epidemiological data on AIDS indicate that the adult prevalence of the disease in Nairobi will increase from 14% in 1992 to 24% by the year 2005, while prevalence in all of Kenya will increase from 5.6 to 9% during that period. Between 1992 and 2005, the cost of HIV/AIDS is expected to increase from $20,339 to $48,402 in heavy industry, from $67,183 to $163,685 in transportation, from $184,543 to $533,054 in wood processing, and from $285,847 to $866,217 on sugar estates. Thus, labor costs are likely to rise significantly and reduce company profits unless there are appropriate prevention efforts in the workplace. A disproportionately high percentage of the costs will be due to presence of the disease among higher level staff. The most vulnerable companies will be those which are labor-intensive and those which offer the most employee benefits. This assessment will help convince business leaders and policy-makers of the financial benefits of prevention.

Projection of the year 2050 burden of diabetes in the US adult population: dynamic modeling of incidence, mortality, and prediabetes prevalence

PubMed Central

2010-01-01

Background People with diabetes can suffer from diverse complications that seriously erode quality of life. Diabetes, costing the United States more than $174 billion per year in 2007, is expected to take an increasingly large financial toll in subsequent years. Accurate projections of diabetes burden are essential to policymakers planning for future health care needs and costs. Methods Using data on prediabetes and diabetes prevalence in the United States, forecasted incidence, and current US Census projections of mortality and migration, the authors constructed a series of dynamic models employing systems of difference equations to project the future burden of diabetes among US adults. A three-state model partitions the US population into no diabetes, undiagnosed diabetes, and diagnosed diabetes. A four-state model divides the state of "no diabetes" into high-risk (prediabetes) and low-risk (normal glucose) states. A five-state model incorporates an intervention designed to prevent or delay diabetes in adults at high risk. Results The authors project that annual diagnosed diabetes incidence (new cases) will increase from about 8 cases per 1,000 in 2008 to about 15 in 2050. Assuming low incidence and relatively high diabetes mortality, total diabetes prevalence (diagnosed and undiagnosed cases) is projected to increase from 14% in 2010 to 21% of the US adult population by 2050. However, if recent increases in diabetes incidence continue and diabetes mortality is relatively low, prevalence will increase to 33% by 2050. A middle-ground scenario projects a prevalence of 25% to 28% by 2050. Intervention can reduce, but not eliminate, increases in diabetes prevalence. Conclusions These projected increases are largely attributable to the aging of the US population, increasing numbers of members of higher-risk minority groups in the population, and people with diabetes living longer. Effective strategies will need to be undertaken to moderate the impact of these factors on national diabetes burden. Our analysis suggests that widespread implementation of reasonably effective preventive interventions focused on high-risk subgroups of the population can considerably reduce, but not eliminate, future increases in diabetes prevalence.

From August to November 2017, Madagascar endured an outbreak of plague. A total of 2417 cases of plague were confirmed, causing a death toll of 209. Public health intervention efforts were introduced and successfully stopped the epidemic at the end of November. The plague, however, is endemic in the region and occurs annually, posing the risk of future outbreaks. To understand the plague transmission, we collected real-time data from official reports, described the outbreak's characteristics, and estimated transmission parameters using statistical and mathematical models. The pneumonic plague epidemic curve exhibited multiple peaks, coinciding with sporadic introductions of new bubonic cases. Optimal climate conditions for rat flea to flourish were observed during the epidemic. Estimate of the plague basic reproduction number during the large wave of the epidemic was high, ranging from 5 to 7 depending on model assumptions. The incubation and infection periods for bubonic and pneumonic plague were 4.3 and 3.4 days and 3.8 and 2.9 days, respectively. Parameter estimation suggested that even with a small fraction of the population exposed to infected rat fleas (1/10,000) and a small probability of transition from a bubonic case to a secondary pneumonic case (3%), the high human-to-human transmission rate can still generate a large outbreak. Controlling rodent and fleas can prevent new index cases, but managing human-to-human transmission is key to prevent large-scale outbreaks. Copyright © 2018 The Authors. Published by Elsevier B.V.

Combining epidemiology and biomechanics in sports injury prevention research: a new approach for selecting suitable controls.

PubMed

Finch, Caroline F; Ullah, Shahid; McIntosh, Andrew S

2011-01-01

Several important methodological issues need to be considered when designing sports injury case-control studies. Major design goals for case-control studies include the accounting for prior injury risk exposure, and optimal definitions of both cases and suitable controls are needed to ensure this. This article reviews methodological aspects of published sports injury case-control studies, particularly with regard to the selection of controls. It argues for a new approach towards selecting controls for case-control studies that draws on an interface between epidemiological and biomechanical concepts. A review was conducted to identify sport injury case-control studies published in the peer-review literature during 1985-2008. Overall, 32 articles were identified, of which the majority related to upper or lower extremity injuries. Matching considerations were used for control selection in 16 studies. Specific mention of application of biomechanical principles in the selection of appropriate controls was absent from all studies, including those purporting to evaluate the benefits of personal protective equipment to protect against impact injury. This is a problem because it could lead to biased conclusions, as cases and controls are not fully comparable in terms of similar biomechanical impact profiles relating to the injury incident, such as site of the impact on the body. The strength of the conclusions drawn from case-control studies, and the extent to which results can be generalized, is directly influenced by the definition and recruitment of cases and appropriate controls. Future studies should consider the interface between epidemiological and biomechanical concepts when choosing appropriate controls to ensure that proper adjustment of prior exposure to injury risk is made. To provide necessary guidance for the optimal selection of controls in case-control studies of interventions to prevent sports-related impact injury, this review outlines a new case-control selection strategy that reflects the importance of biomechanical considerations, which ensures that controls are selected based on the presence of the same global injury mechanism as the cases. To summarize, the general biomechanical principles that should apply to the selection of controls in future case-control studies are as follows: (i) each control must have been exposed to the same global injury mechanism as the case, (e.g. head impact, fall onto outstretched arm); and (ii) intrinsic (individual) factors (e.g. age, sex, skill level) that might modify the person's response to the relevant biomechanical loads are adjusted when either selecting the controls or are in the analysis phase. The same considerations for control selection apply to other study designs such as matched cohort studies or case-crossover studies.

The role of hypoxia in oral cancer and potentially malignant disorders: a review.

2017-04-01

Oral and oropharyngeal cancer are major health problems globally with over 500 000 new cases diagnosed annually. Despite the fact that oral cancer is a preventable disease and has the potential for early detection, the overall survival rate remains at around 50%. Most oral cancer cases are preceded by a group of clinical lesions designated 'potentially malignant disorders'. It is difficult to predict if and when these lesions may transform to malignancy, and in turn it is difficult to agree on appropriate management strategies. Understanding underlying molecular pathways would help in predicting the malignant transformation of oral potentially malignant disorders and ultimately identifying effective methods for early detection and prevention of oral cancer. Reprogramming energy metabolism is an emerging hallmark of cancer that is predominantly controlled by hypoxia-induced genes regulating angiogenesis, tumour vascularization, invasion, drug resistance and metastasis. This review aims to highlight the role of hypoxia in oral carcinogenesis and to suggest future research implications in this arena. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

2012-01-01

Water services are a strategic sector of large social and economic relevance. It is therefore essential that they are managed rationally and efficiently. Advanced water supply and wastewater infrastructure asset management (IAM) is key in achieving adequate levels of service in the future, particularly with regard to reliable and high quality drinking water supply, prevention of urban flooding, efficient use of natural resources and prevention of pollution. This paper presents a methodology for supporting the development of urban water IAM, developed during the AWARE-P project as well as an appraisal of its implementation in four water utilities. Both water supply and wastewater systems were considered. Due to the different contexts and features of the utilities, the main concerns vary from case to case; some problems essentially are related to performance, others to risk. Cost is a common deciding factor. The paper describes the procedure applied, focusing on the diversity of drivers, constraints, benefits and outcomes. It also points out the main challenges and the results obtained through the implementation of a structured procedure for supporting urban water IAM.

Emergency contraceptive use in Addis Ababa, Ethiopia: Challenging common assumptions about young people's contraceptive practices.

Both, Rosalijn

2015-05-01

Drawing on an ethnographic case study of young people's (aged 18-29) use of emergency contraceptives (ECs) in Addis Ababa, Ethiopia, this article highlights areas of disconnect between how reproductive health experts envision EC use and local meanings ascribed to ECs by young people. ECs - designed by reproductive health experts to be used only in case of emergency - were preferred by study participants over other contraceptive methods because of their ease of use, discreetness, perceived minimal side effects on beauty and future fertility, and usefulness in navigating reproductive intentions. The findings point to features that young people find desirable when it comes to contraceptive methods and suggest that common assumptions of reproductive health experts about young people's contraceptive practices need to be reconsidered, namely: 1) that young people can plan for prevention of unwanted pregnancy by buying a contraceptive method in advance; 2) that existing contraceptive technologies are appropriate for young people; 3) that young people prefer to use modern contraceptive methods; and 4) that young people in premarital relationships aim to prevent unplanned pregnancy.

Accessibility analysis of urban emergency shelters can help support urban disaster prevention planning. Pre-disaster emergency evacuation zoning has become a significant topic on disaster prevention and mitigation research. In this study, we assessed the level of serviceability of urban emergency shelters within maximum capacity, usability, sufficiency and a certain walking time limit by employing spatial analysis techniques of GIS-Network Analyst. The methodology included the following aspects: the distribution analysis of emergency evacuation demands, the calculation of shelter space accessibility and the optimization of evacuation destinations. This methodology was applied to Adana, a city in Turkey, which is located within the Alpine-Himalayan orogenic system, the second major earthquake belt after the Pacific-Belt. It was found that the proposed methodology could be useful in aiding to understand the spatial distribution of urban emergency shelters more accurately and establish effective future urban disaster prevention planning. Additionally, this research provided a feasible way for supporting emergency management in terms of shelter construction, pre-disaster evacuation drills and rescue operations.

Occupational asthma: a review.

Occupational asthma is the most common form of occupational lung disease in the developed world at the present time. In this review, the epidemiology, pathogenesis/mechanisms, clinical presentations, management, and prevention of occupational asthma are discussed. The population attributable risk of asthma due to occupational exposures is considerable. Current understanding of the mechanisms by which many agents cause occupational asthma is limited, especially for low-molecular-weight sensitizers and irritants. The diagnosis of occupational asthma is generally established on the basis of a suggestive history of a temporal association between exposure and the onset of symptoms and objective evidence that these symptoms are related to airflow limitation. Early diagnosis, elimination of exposure to the responsible agent, and early use of inhaled steroids may play important roles in the prevention of long-term persistence of asthma. Persistent occupational asthma is often associated with substantial disability and consequent impacts on income and quality of life. Prevention of new cases is the best approach to reducing the burden of asthma attributable to occupational exposures. Future research needs are identified. PMID:10931788

The introduction of Zika virus into the Region of the Americas (Americas) and the subsequent increase in cases of congenital microcephaly resulted in activation of CDC's Emergency Operations Center on January 22, 2016, to ensure a coordinated response and timely dissemination of information, and led the World Health Organization to declare a Public Health Emergency of International Concern on February 1, 2016. During the past year, public health agencies and researchers worldwide have collaborated to protect pregnant women, inform clinicians and the public, and advance knowledge about Zika virus (Figure 1). This report summarizes 10 important contributions toward addressing the threat posed by Zika virus in 2016. To protect pregnant women and their fetuses and infants from the effects of Zika virus infection during pregnancy, public health activities must focus on preventing mosquito-borne transmission through vector control and personal protective practices, preventing sexual transmission by advising abstention from sex or consistent and correct use of condoms, and preventing unintended pregnancies by reducing barriers to access to highly effective reversible contraception.

Prevention of alveolar echinococcosis--ecosystem and risk management perspectives in Japan.

PubMed

Konno, Keita; Oku, Yuzaburo; Tamashiro, Hiko

2003-12-01

We focused on the epidemiology of alveolar echinococcosis especially in Japan and discussed control measures to prevent an epidemic. No effective control measures against alveolar echinococcosis have been identified thus far because it is difficult to fully understand the ecology of the parasite and its hosts, i.e. the precise infection route to humans. In Hokkaido, Japan, infection rates among red foxes have recently risen even in low endemic districts. Infection seems to be spreading not only among wild foxes but also among domestic dogs. Despite only sporadic reports of human cases in Japan, we predict that the incidence of alveolar echinococcosis will increase in the near future if no effective preventive measures are put in place. An Echinococcus multilocularis epidemic would have the potential to affect the economy of Hokkaido, due to its impact on the agricultural and tourist industries. Well-designed epidemiological surveys are, therefore, urgently required prior to large outbreaks, based on understanding of the ecosystem around E. multilocularis.

Fire deaths in aircraft without the crashworthy fuel system.

Cases reported to the Armed Forces Institute of Pathology were examined for occupants of helicopters without the crashworthy fuel system (CWFS) who survived crashes but died as a result of postcrash fires. There were 16 fire deaths in the 9 such accidents which occurred between January 1976 and April 1984. All of these victims would have survived if there had been no postcrash fire. Partial body destruction by fire probably prevented inclusion of many other cases. The dramatic reduction in fire deaths and injuries due to installation of the CWFS in Army helicopters is discussed. The author concludes that fire deaths and injuries in aircraft accidents could almost be eliminated by fitting current and future aircraft with the CWFS.

It is now widely acknowledged that water management discipline is transforming, from being a public health and flood prevention challenge of the nineteenth century to a multi-dimensional challenge of water security for the twenty-first century. In order to train water engineers to be capable of working with this holistic multi-dimensional approach, a new paradigm in engineering education is required. Adjustments already made to undergraduate coursework are not enough; this new paradigm requires modifications to the PhD in engineering, with greater emphasis on interdisciplinary case study research. Such a change can deliver PhD graduates with both sufficient social and technical knowledge, who can then go on to become the hybrid lecturers crucially needed for training future water engineers.

We describe the case of a 40-year-old female myope who presented for bilateral LASIK. Intra-operatively, the microkeratome oscillating pin broke during flap creation resulting in the separation of the disposable blade from the motor. This resulted in an irregular flap with missing pieces. The procedure was abandoned and the macerated partial flap repositioned as best as possible. The patient recovered a BCVA of 6/7.5. The manufacturer has since reported taking corrective measures to prevent this problem in the future. This case is a reminder that despite care and maintenance by user and manufacturer, extreme and rare hardware malfunctions can occur. Furthermore, although potentially sight threatening if managed well these complications can be followed by good recovery of vision.

Epilepsy and videogames.

Since the first case of videogame (VG) epilepsy was reported in 1981, many cases of seizures triggered by VGs were reported, not only in photosensitive, but also in non-photosensitive children and adolescents with epilepsy. We provide an overview of the literature with overall conclusions and recommendations regarding VG playing. Specific preventive measures concerning the physical characteristics of images included in commercially available VGs (flash rate, choice of colors, patterns, and contrast) can lead in the future to a clear decrease of this problem. In addition to the positive effect of such measures, the collaborative studies performed in France and in the rest of Europe have stressed the importance of a safe distance to the screen of > or = 2 m, and the less provocative role of 100-Hz screens.

Infection with HPV 16 and 18, the major causative agents of cervical cancer, can be prevented through vaccination with a bivalent or quadrivalent vaccine. Both vaccines provide cross-protection against HPV-types not included in the vaccines. In particular, the bivalent vaccine provides additional protection against HPV 31, 33, and 45 and the quadrivalent vaccine against HPV31. The quadrivalent vaccine additionally protects against low-risk HPV type 6 and 11, responsible for most cases of genital warts. In this study, we made an analytical comparison of the two vaccines in terms of cost-effectiveness including the additional benefits of cross-protection and protection against genital warts in comparison with a screening-only strategy. We used a Markov model, simulating the progression from HPV infection to cervical cancer or genital warts. The model was used to estimate the difference in future costs and health effects of both HPV-vaccines separately. In a cohort of 100,000 women, use of the bivalent or quadrivalent vaccine (both at 50% vaccination coverage) reduces the cervical cancer incidence by 221 and 207 cases, corresponding to ICERs of €17,600/QALY and €18,900/QALY, respectively. It was estimated that the quadrivalent vaccine additionally prevents 4390 cases of genital warts, reducing the ICER to €16,300/QALY. Assuming a comparable willingness to pay for cancer and genital warts prevention, the difference in ICERs could justify a slightly higher price (~7% per dose) in favor of the quadrivalent vaccine. Clearly, HPV vaccination has been implemented for the prevention of cervical cancer. From this perspective, use of the bivalent HPV vaccine appears to be most effective and cost-effective. Including the benefits of prevention against genital warts, the ICER of the quadrivalent HPV vaccine was found to be slightly more favourable. However, current decision-making on the introduction of HPV is driven by the primary cervical cancer outcome. New vaccine tenders could consider the benefits of cross-protection and the benefits of genital warts, which requires more balanced decision-making.

Model development for household waste prevention behaviour.

2012-12-01

Understanding waste prevention behaviour (WPB) could enable local governments and decision makers to design more-effective policies for reducing the amount of waste that is generated. By merging well-known attitude-behaviour theories with elements from wider models from environmental psychology, an extensive cognitive framework that provides new and valuable insights is developed for understanding the involvement of individuals in waste prevention. The results confirm the usefulness of the theory of planned behaviour and of Schwartz's altruistic behaviour model as bases for modelling participation in waste prevention. A more elaborate integrated model of prevention was shown to be necessary for the complete analysis of attitudinal aspects associated with waste prevention. A postal survey of 158 respondents provided empirical support for eight of 12 hypotheses. The proposed structural equation indicates that personal norms and perceived behaviour control are the main predictors and that, unlike the case of recycling, subjective norms have a weak influence on WPB. It also suggests that, since social norms have not presented a direct influence, WPB is likely to be influenced by a concern for the environment and the community as well by perceptions of moral obligation and inconvenience. Results also proved that recycling and waste prevention represent different dimensions of waste management behaviour requiring particular approaches to increase individuals' engagement in future policies.

OBJECTIVE Proximal junctional kyphosis (PJK) is a well-recognized complication of surgery for adult spinal deformity and is characterized by increased kyphosis at the upper instrumented vertebra (UIV). PJK prevention strategies have the potential to decrease morbidity and cost by reducing rates of proximal junctional failure (PJF), which the authors define as radiographic PJK plus clinical sequelae requiring revision surgery. METHODS The authors performed an analysis of 195 consecutive patients with adult spinal deformity. Age, sex, levels fused, upper instrumented vertebra (UIV), use of 3-column osteotomy, pelvic fixation, and mean time to follow-up were collected. The authors also reviewed operative reports to assess for the use of surgical adjuncts targeted toward PJK prevention, including ligament augmentation, hook fixation, and vertebroplasty. The cost of surgery, including direct and total costs, was also assessed at index surgery and revision surgery. Only revision surgery for PJF was included. RESULTS The mean age of the cohort was 64 years (range 25-84 years); 135 (69%) patients were female. The mean number of levels fused was 10 (range 2-18) with the UIV as follows: 2 cervical (1%), 73 upper thoracic (37%), 108 lower thoracic (55%), and 12 lumbar (6%). Ligament augmentation was used in 99 cases (51%), hook fixation in 60 cases (31%), and vertebroplasty in 71 cases (36%). PJF occurred in 18 cases (9%). Univariate analysis found that ligament augmentation and hook fixation were associated with decreased rates of PJF. However, in a multivariate model that also incorporated age, sex, and UIV, only ligament augmentation maintained a significant association with PJF reduction (OR 0.196, 95% CI 0.050-0.774; p = 0.020). Patients with ligament augmentation, compared with those without, had a higher cost of index surgery, but ligament augmentation was overall cost effective and produced significant cost savings. In sensitivity analyses in which we independently varied the reduction in PJF, cost of ligament augmentation, and cost of reoperation by ± 50%, ligament augmentation remained a cost-effective strategy for PJF prevention. CONCLUSIONS Prevention strategies for PJK/PJF are limited, and their cost-effectiveness has yet to be established. The authors present the results of 195 patients with adult spinal deformity and show that ligament augmentation is associated with significant reductions in PJF in both univariate and multivariate analyses, and that this intervention is cost-effective. Future studies will need to determine if these clinical results are reproducible, but for high-risk cases, these data suggest an important role of ligament augmentation for PJF prevention and cost savings.

Final Design for a Comprehensive Orbital Debris Management Program

NASA Technical Reports Server (NTRS)

1990-01-01

The rationale and specifics for the design of a comprehensive program for the control of orbital debris, as well as details of the various components of the overall plan, are described. The problem of orbital debris has been steadily worsening since the first successful launch in 1957. The hazards posed by orbital debris suggest the need for a progressive plan for the prevention of future debris, as well as the reduction of the current debris level. The proposed debris management plan includes debris removal systems and preventative techniques and policies. The debris removal is directed at improving the current debris environment. Because of the variance in sizes of debris, a single system cannot reasonably remove all kinds of debris. An active removal system, which deliberately retrieves targeted debris from known orbits, was determined to be effective in the disposal of debris tracked directly from earth. However, no effective system is currently available to remove the untrackable debris. The debris program is intended to protect the orbital environment from future abuses. This portion of the plan involves various environment from future abuses. This portion of the plan involves various methods and rules for future prevention of debris. The preventative techniques are protective methods that can be used in future design of payloads. The prevention policies are rules which should be employed to force the prevention of orbital debris.

Although propofol is one of the most commonly used drugs for induction of anaesthesia, it is not devoid of anaphylactic potential. Early detection of any suspected anaphylactic reaction during anaesthesia, prompt management, identification of the offending agent and prevention of exposure to the offending agent in the future is the responsibility of the anaesthesiologist. This is a case report of anaphylaxis to propofol at the induction of anaesthesia in a previously non-allergic 56 year-old man, planned to undergo laparoscopic nephrectomy, who responded to epinephrine infusion.

Kenya belongs to a high incidence region known as Africa’s esophageal cancer (EC) corridor. It has one of the highest incidence rates of EC worldwide, but research on EC in Kenya has gone highly unnoticed. EC in Kenya is unique in its high percentage of young cases (< 30 years of age). In this review, we show the current status of EC in the country. We mainly focus on significant risk factors such as alcohol drinking, genetic factors, malnutrition and hot food/drink. Future directions in the study and prevention of EC in Kenya are also discussed. PMID:29082268

Japanese encephalitis (JE) is one of severe viral encephalitis that affects individuals in Asia, western Pacific countries, and northern Australia. Although 67,900 JE cases have been estimated among 24 JE epidemic countries annually, only 10,426 have been reported in 2011. With the establishment of JE surveillance and vaccine use in some countries, the JE incidence rate has decreased; however, serious outbreaks still occur. Understanding JE epidemics and identifying the circulating JE virus genotypes will improve JE prevention and control. This review summarizes the current epidemiology data in these countries.

An outbreak of measles was declared in southern Alberta on October 18, 2013, after a case had been reported to the local public health unit in a non-immunized teenager with recent travel to the Netherlands. The teenager had had contact with a large number of unimmunized people while infectious; therefore, the risk of spread was high. The potential for an outbreak of measles in this area had been identified by the lead Medical Officer of Health for South Zone, and planning for an outbreak had begun in August 2013. Several public health measures were implemented to control the outbreak: mass immunization clinics; an outbreak dose of measles mumps and rubella (MMR) vaccine for infants 6-12 months old; communication within the affected and surrounding communities; a dedicated measles hotline; a Mobile Measles Assessment Team; and a Measles Assessment Centre. A total of 42 confirmed cases were identified during the outbreak between October 16 and November 25. Just over half the cases were male (52.4%). The average age was 12 (range < 1 to 24 years) and the median age 13 years. There was one hospitalization, and no deaths occurred. All cases were unimmunized. Cases were located in five communities immediately surrounding Lethbridge. All but two cases were epidemiologically linked within 10 households. The planning that occurred before the outbreak was essential in containing the outbreak to 10 households. To prevent future outbreaks of measles, exploring strategies for increasing immunization coverage rates in unimmunized populations is essential. When immunization acceptance is not uniform, other public health strategies should be planned for and implemented in order to prevent additional spread.

Nickel is the leading cause of allergic contact dermatitis (ACD) from early childhood through adolescence. Studies have shown that skin piercings and other nickel-laden exposures can trigger the onset of nickel ACD in those who are susceptible. Nickel ACD causes a vast amount of cutaneous disease in children. Cases of nickel ACD in children have been reported in peer-reviewed literature from 28 states. Common items that contain inciting nickel include jewelry, coins, zippers, belts, tools, toys, chair studs, cases for cell phones and tablets, and dental appliances. The diagnosis of nickel ACD has been routinely confirmed by patch testing in children older than 6 months suspected of ACD from nickel. Unlike in Europe, there are no mandatory restrictions legislated for nickel exposure in the United States. Denmark has demonstrated that regulation of the nickel content in metals can lower the risk of ACD and the associated health care-related costs that arise from excess nickel exposure. To further awareness, this article reviews the prominent role of nickel in pediatric skin disease in the United States. It discusses the need for a campaign by caretakers to reduce nickel-related morbidity. Lastly, it promotes the model of European legislation as a successful intervention in the prevention of nickel ACD. © 2015 Wiley Periodicals, Inc.

Since the insertion of the first TIPS in 1989 much has been learned about this therapeutic procedure. It has an established role for the treatment of some complications of portal hypertension: prevention of recurrent variceal bleeding and rescue of patients with acute uncontrollable variceal bleeding. In addition TIPS is useful for Budd-Chiari syndrome, refractory ascites and hepatorenal syndrome, although its specific role in these indications remains to be definitively established. However, the decrease in sinusoidal blood flow induced by TIPS can lead to the patient developing hepatic encephalopathy and liver failure in some cases. Therefore, TIPS should be used withmore » caution in patients with very poor liver function. From a technical point of view, successful placement of TIPS is achieved in more than 98% of cases by experienced groups. At present, evaluation of TIPS dysfunction based on morphology probably leads to an overdiagnosis of this complication since most of these cases are not associated with clinical manifestations (recurrent bleeding or refractory ascites). The major disadvantage of TIPS remains its poor long-term patency requiring a mandatory surveillance program. The indicator for shunt function/malfunction should be the portosystemic pressure gradient, which is best assessed by intravascular measurements. Shunt obstructions may be prevented or reduced by the use of stent-grafts in the future.« less

Epigenetics and Future Generations.

PubMed

Del Savio, Lorenzo; Loi, Michele; Stupka, Elia

2015-10-01

Recent evidence of intergenerational epigenetic programming of disease risk broadens the scope of public health preventive interventions to future generations, i.e. non existing people. Due to the transmission of epigenetic predispositions, lifestyles such as smoking or unhealthy diet might affect the health of populations across several generations. While public policy for the health of future generations can be justified through impersonal considerations, such as maximizing aggregate well-being, in this article we explore whether there are rights-based obligations supervening on intergenerational epigenetic programming despite the non-identity argument, which challenges this rationale in case of policies that affect the number and identity of future people. We propose that rights based obligations grounded in the interests of non-existing people might fall upon existing people when generations overlap. In particular, if environmental exposure in F0 (i.e. existing people) will affect the health of F2 (i.e. non-existing people) through epigenetic programming, then F1 (i.e. existing and overlapping with both F0 and F2) might face increased costs to address F2's condition in the future: this might generate obligations upon F0 from various distributive principles, such as the principle of equal opportunity for well being. © 2015 John Wiley & Sons Ltd.

To forecast the future trend of betel nut-associated oral cancer and the resulting burden on health based on historical oral cancer patient data in Hunan province, China. Oral cancer patient data in five hospitals in Changsha (the capital city of Hunan province) were collected for the past 12 years. Three methods were used to analyse the data; Microsoft Excel Forecast Sheet, Excel Trendline, and the Logistic growth model. A combination of these three methods was used to forecast the future trend of betel nut-associated oral cancer and the resulting burden on health. Betel nut-associated oral cancer cases have been increasing rapidly in the past 12  years in Changsha. As of 2016, betel nuts had caused 8,222 cases of oral cancer in Changsha and close to 25,000 cases in Hunan, resulting in about ¥5 billion in accumulated financial loss. The combined trend analysis predicts that by 2030, betel nuts will cause more than 100,000 cases of oral cancer in Changsha and more than 300,000 cases in Hunan, and more than ¥64 billion in accumulated financial loss in medical expenses. The trend analysis of oral cancer patient data predicts that the growing betel nut industry in Hunan province will cause a humanitarian catastrophe with massive loss of human life and national resources. To prevent this catastrophe, China should ban betel nuts and provide early oral cancer screening for betel nut consumers as soon as possible.

[Professional error and nursing ethics: from past consideration to future strategy].

Germini, Francesco; Lattarulo, Pio

2008-01-01

In 1960, the National Federation IPASVI emanated its first ethical code which does not deal at all with the prevention of error or how to behave in the case this does happen, with the exception of point 6, which recommends scrupulously respecting the therapy prescribed and encouraging patients to trust the physicians and the other health workers. The second ethical code was dated 1977. In this eighteen year interval the hospital organization had been deeply modified and this new layout of the Code reflected some remarkable changes of thought but no precise reference to the matter of error management. In the 1999 version of the code the radical changes in the profession are reflected and formally recognized by the law (42/1999) and by society acting as a reference for the regulation of the nursing profession and referring to one of the most ancient principles of medicine, the "primum non nocere". It is important to remember that an ethical code derives from professional considerations, applied to the context of "here and now". Some strategic considerations for the future regarding the important role of risk prevention and management of errors (which do, unfortunately, occur) are therefore expressed.

Autism Narratives in Media Coverage of the MMR Vaccine-Autism Controversy under a Crip Futurism Framework.

PubMed

Mann, Benjamin W

2018-03-09

While previous studies in health communication have examined online news media regarding autism, there is a lack of research that critically examines how such media representations may stigmatize autism and seeks to eliminate the condition, particularly in the context of the resurging measles, mumps, and rubella (MMR) vaccine-autism controversy. To address this gap in the literature, this study analyzes 153 articles that engage the MMR vaccine-autism controversy from the top 10 online news sources in the U.S. from September 2015 through July 2017. It draws from Kafer's (2013) work in Feminist, Crip, Queer, using a lens of crip futurism to interpret three major narrative themes: a death and survival narrative that purports autism as a worst-case scenario, a societal problem narrative, and a preventative narrative that seeks to eliminate the condition. These themes suggest that online news media narratives about autism surrounding the autism-MMR controversy play into stereotypes about autism, including stigmatization and prioritization of preventive behaviors and cures over supporting the lived experiences of autistic individuals. Continued research on the impact of online media portrayals of autism specifically, and disability in health contexts generally, is called for.

Present and future of developmental neuropsychopharmacology.

PubMed

Arango, Celso

2015-05-01

The field of child and adolescent psychiatry has always lagged behind adult psychiatry. With recent evidence that the vast majority of mental disorders, even when they emerge in adulthood, cause abnormal neurodevelopment and resultant emphasis on prevention and early intervention, there is a need to put child psychiatry at the top of the agenda in mental health research. This should also be the case for developmental neuropsychopharmacology. The target of drug discovery should shift toward a population younger than the one that is typically included in clinical trials. This is not only a matter of trying to replicate what has been found in individuals with mature brains; it is about searching for new strategies that address developing brains while the therapeutic window for their effect is still open. At present, major concerns in developmental psychopharmacology are over-prescription rates and use of psychotropic medications for conditions with a particularly underdeveloped evidence base, as well as adverse effects, especially potentially life-shortening cardiometabolic effects and suicidal ideation. The future of research in this area should focus on the use of drugs for primary and secondary prevention that would modify abnormal brain development. Copyright © 2014 Elsevier B.V. and ECNP.

Training Rapid Stepping Responses in an Individual With Stroke

PubMed Central

Inness, Elizabeth L.; Komar, Janice; Biasin, Louis; Brunton, Karen; Lakhani, Bimal; McIlroy, William E.

2011-01-01

Background and Purpose Compensatory stepping reactions are important responses to prevent a fall following a postural perturbation. People with hemiparesis following a stroke show delayed initiation and execution of stepping reactions and often are found to be unable to initiate these steps with the more-affected limb. This case report describes a targeted training program involving repeated postural perturbations to improve control of compensatory stepping in an individual with stroke. Case Description Compensatory stepping reactions of a 68-year-old man were examined 52 days after left hemorrhagic stroke. He required assistance to prevent a fall in all trials administered during his initial examination because he showed weight-bearing asymmetry (with more weight borne on the more-affected right side), was unable to initiate stepping with the right leg (despite blocking of the left leg in some trials), and demonstrated delayed response times. The patient completed 6 perturbation training sessions (30–60 minutes per session) that aimed to improve preperturbation weight-bearing symmetry, to encourage stepping with the right limb, and to reduce step initiation and completion times. Outcomes Improved efficacy of compensatory stepping reactions with training and reduced reliance on assistance to prevent falling were observed. Improvements were noted in preperturbation asymmetry and step timing. Blocking the left foot was effective in encouraging stepping with the more-affected right foot. Discussion This case report demonstrates potential short-term adaptations in compensatory stepping reactions following perturbation training in an individual with stroke. Future work should investigate the links between improved compensatory step characteristics and fall risk in this vulnerable population. PMID:21511992

The case of national health promotion policy in Australia: where to now?

Smith, James A; Crawford, Gemma; Signal, Louise

2016-04-01

Issue addressed Over the last three decades there has been an incremental investment in health promotion and prevention across Australia; yet, the Commonwealth Government and some state/territory governments have more recently instigated funding cuts in health promotion and prevention. This paper argues that the role of health promotion is critical in contemporary Australia and discusses strategies needed to move forward within the context of recent disinvestments. Discussion Key areas of concern relating to recent health promotion and prevention disinvestment in Australia include the abolishment of the Australian National Preventive Health Agency, the cessation of the National Partnership Agreement on Preventive Health and significant cuts to Indigenous programs. These changes pose a significant threat to the health, economic and social well being of Australians and the region, particularly those that are most vulnerable. Conclusions Future health promotion and prevention efforts will require strategic leadership and action to enhance the promotion of health equity in Australia over the coming decades. We call on governments to (re)invest in health promotion and prevention both in and outside the health sector so that health promotion professionals can continue their advocacy efforts aimed at articulating their professional place in improving population health. So what? Recent changes to national health promotion and prevention policy are detrimental to the health and well being of the Australian population, particularly those most vulnerable. Sound planning to revitalise and refocus health promotion action in Australia is urgently required.

Design participation as an insurance: risk-management and end-user participation in the development of information systems in healthcare organizations.

PubMed

Vimarlund, V; Timpka, T

2002-01-01

The aim of this paper is to build a theoretical framework for analysis of when decision-makers should use end-user participation as a form of insurance for unforeseen consequences of implementing information systems in healthcare organizations. Data were collected in a case study of an information system development project in a small clinical setting. During the initial phase, the future end-users of the system were allowed to actively influence the system design and test every new tool that was considered for implementation. The results of the case study suggest that when time and effort are invested in allowing healthcare staff to participate in information system development processes, the benefits can well exceed the costs throughout the life cycle of the project. Risk-averse decision-makers fearing negative secondary consequences of a HIS, with regard to clinical work flow, will always adopt measures to prevent future failures, if they can find a possibility of shifting these risks. Therefore, they calculate the present discounted value of the effects accrued over time to the unit and predict the amount of resources they are willing to pay to acquire on insurance (such as design participation) that will protect the organization from future losses. End-user participation in the design process can be the key positive influence on the quality of the service and, thereby, organizational effectiveness. Investments in broad design participation can, consequently, be a productive activity that transforms potential current income into future benefits.

Competent patients have the right to refuse treatment and healthcare workers should acknowledge their wishes. In the Netherlands there are conflicting (constitutional) rights of the foetus and of mentally ill patients. This paper describes the legal and ethical problems in the case of a mentally ill patient at 37 weeks of pregnancy who refused an obstetric examination. The patient refused to cooperate and have her physical condition and mental status examined. Her refusal endangered the life of the foetus. The obstetrician decided to perform a caesarean section, even if this would be in conflict with the patient's right to self-determination. In these cases no legal framework exists for providing the best medical care. New legislation should be drawn up to prevent similar cases occurring in the future. If a caesarean section is in conflict with a patient's right to self-determination, it should always be performed as a last resort.

Large, long standing goiters present multiple challenges to anaesthesiologist. Post thyroidectomy haematoma is a rare but life threatening complication of thyroid surgery leading to airway obstruction. We report a case of huge goiter that underwent near total thyroidectomy and developed post thyroidectomy haematoma. Within no time it resulted in near fatal airway obstruction, pulmonary oedema and cardiac arrest. The haematoma was evacuated immediately and patient was resuscitated successfully. Pulmonary oedema was further worsened by subsequent aggressive fluid resuscitation. She was electively ventilated with PEEP and was extubated after five days. Except for right vocal cord palsy her postoperative stay was uneventful. This is unique case where a post thyoidectomy haematoma has resulted in fatal supraglottic oedema and pulmonary oedema. Early recognition, immediate intubation and evacuation of haematoma are the key to manage this complication. We highlight on the pathophysiology of haematoma and discuss the strategies to prevent similar events in future.

At least four workers at a metal recycling facility were hospitalized and one died after exposure to chlorine gas when it was accidentally released from an intact, closed-valved cylinder being processed for scrap metal. This unintentional chlorine gas release marks at least the third such incident at a metal recycling facility in the United States since 2010. We describe the fatal case of the worker whose clinical course was consistent with acute respiratory distress syndrome (ARDS) following exposure to high concentrations of chlorine gas. This case report emphasizes the potential risk of chlorine gas exposure to metal recycling workers by accepting and processing intact, closed-valved containers. The metal recycling industry should take steps to increase awareness of this established risk to prevent future chlorine gas releases. Additionally, public health practitioners and clinicians should be aware that metal recycling workers are at risk for chlorine gas exposure. © 2018 Wiley Periodicals, Inc.

During August 2009–October 2010, a multidisciplinary team investigated 14 outbreaks of animal and human anthrax in Bangladesh to identify the etiology, pathway of transmission, and social, behavioral, and cultural factors that led to these outbreaks. The team identified 140 animal cases of anthrax and 273 human cases of cutaneous anthrax. Ninety one percent of persons in whom cutaneous anthrax developed had history of butchering sick animals, handling raw meat, contact with animal skin, or were present at slaughtering sites. Each year, Bacillus anthracis of identical genotypes were isolated from animal and human cases. Inadequate livestock vaccination coverage, lack of awareness of the risk of anthrax transmission from animal to humans, social norms and poverty contributed to these outbreaks. Addressing these challenges and adopting a joint animal and human health approach could contribute to detecting and preventing such outbreaks in the future. PMID:22492157

Osteoporosis is a frequent disease in many populations. The hallmark is fragility fractures, which are harbingers of future fractures, disability, mortality and cost on society. The occurrence increases with age, low vitamin D level and smoking. Smoking rates are high, vitamin D is low and life expectancy is rising steeply in Greenland, as is the need for focus on osteoporosis. We report a case that uses a simple and readily available tool to diagnose osteoporosis at the hospital in Sisimiut, a town of 5000 inhabitants on the west coast of Greenland. A 51-year-old Inuit woman was seen due to lower back pain. No trauma could be recalled. Laboratory results showed a low vitamin D level and normal S-calcium, S-phosphate, S-parathyroid hormone, S-thyrotropin, erythrocyte sedimentation rate, S-creatinine and hemoglobin. The lateral chest radiograph demonstrated a reduction of anterior height of the seventh and ninth thoracic vertebral bodies of 50% and 40% respectively. Chest radiographs are frequently done in the towns along the vast coastline of Greenland, the world's largest island. They are transferred to the hospital in the capital city Nuuk using existing tele-technology, and specialist evaluations are given in electronic records available at the coastal hospitals. Effective therapies for osteoporosis are available and the identification of vertebral fractures that merit treatment may prevent future fractures, morbidity and mortality. Fragility fractures are frequent in old age and the steep rise in life expectancy and in the number of old people in Greenland emphasize the need for a focus on management of osteoporosis. Geography provides a diagnostic challenge to rural and remote areas that can be overcome by the use of lateral chest radiographs as it relies on facilities readily available. Clinical risk assessment tools with high specificity may support further osteoporosis risk prediction in remote Arctic societies.

2006-01-01

Background In England and Wales where less than 1% of the population are Injecting drug users (IDUs), 97% of HCV reports are attributed to injecting drug use. As over 60% of the IDU population will have been imprisoned by the age of 30 years, prison may provide a good location in which to offer HCV screening and treatment. The aim of this work is to examine the cost effectiveness of a number of alternative HCV case-finding strategies on prison reception Methods A decision analysis model embedded in a model of the flow of IDUs through prison was used to estimate the cost effectiveness of a number of alternative case-finding strategies. The model estimates the average cost of identifying a new case of HCV from the perspective of the health care provider and how these estimates may evolve over time. Results The results suggest that administering verbal screening for a past positive HCV test and for ever having engaged in illicit drug use prior to the administering of ELISA and PCR tests can have a significant impact on the cost effectiveness of HCV case-finding strategies on prison reception; the discounted cost in 2017 being £2,102 per new HCV case detected compared to £3,107 when no verbal screening is employed. Conclusion The work here demonstrates the importance of targeting those individuals that have ever engaged in illicit drug use for HCV testing in prisons, these individuals can then be targeted for future intervention measures such as treatment or monitored to prevent future transmission.

The Kosi floods of Bihar in 2008 led to initial rapid displacement followed by rehabilitation of the affected population. Strategically planned phase-wise activity of supplementary as well as primary measles vaccination combined with a variety of other interventions proved to be successful in preventing outbreaks and deaths due to measles. While 70% supplementary measles vaccination coverage was achieved in relief camps, the coverage of primary measles doses in the latter phases was dependant on accessibility of villages and previous vaccination status of eligible beneficiaries. The integrated diseases surveillance system, which became operational during the floods, also complemented the vaccination efforts by providing daily figures of cases with fever and rash. The overall response was not only successful in terms of preventing measles mortality, but also provided vital lessons that may be useful for planning future vaccination responses in emergency settings.

Motivational Antecedents of Preventive Proactivity in Late Life: Linking Future Orientation and Exercise1

Future orientation is considered as a motivational antecedent of late-life proactivity. In a panel study of 453 old-old adults, we linked future orientation to exercise, a key component of late-life proactivity. Findings based on hierarchical linear modeling reveal that future orientation at baseline predicts changes in exercise during the subsequent four years. Whereas exercise behavior generally declined over time, future orientation and female gender were associated with smaller decline. These results suggest that future-oriented thinking has a lasting impact on health promotion behavior. Future orientation thus represents a dispositional antecedent of preventive proactivity as proposed in our successful aging model. PMID:18080009

Salmonella enteritidis has emerged as the most prevalent cause of human salmonellosis in Canada. Recent trends of S. enteritidis subtypes and their potential sources were described by integrating Salmonella data from several Canadian surveillance and monitoring programmes. A threefold increase in S. enteritidis cases from 2003 to 2009 was identified to be primarily associated with phage types 13, 8 and 13a. Other common phage types (4, 1, 6a) showed winter seasonality and were more likely to be associated with cases linked to international travel. Conversely, phage types 13, 8 and 13a had summer seasonal peaks and were associated with cases of domestically acquired infections. During agri-food surveillance, S. enteritidis was detected in various commodities, most frequently in chicken (with PT13, PT8 and PT13a predominating). Antimicrobial resistance was low in human and non-human isolates. Continued integrated surveillance and collaborative prevention and control efforts are required to mitigate future illness.

Although suicidal behavior in children and adolescents is a major public health problem, large-scale research on suicide in this population is uncommon. In this study, we reviewed autopsy and field reports for all pediatric suicide cases referred to the New Mexico Office of the Medical Investigator from 1979 to 2005. The age-adjusted suicide rate was 4.8 per 100,000. Psychologic stressors and parasuicidal behavior were identified in some cases. Seventy-six percent of suicides occurred in the victim's home or yard, and 25% left a suicide note. In 26% of cases, alcohol or other drugs were detected in postmortem. Gunshot wound was the most common method overall (58%), followed by hanging (30%). Although the age-adjusted suicide rate is higher in New Mexico than nationally, the trends in the population are similar. With a solid understanding of the circumstances, it may be possible to predict, and hopefully prevent, future cases of child and adolescent death.

The aim of this study is to forecast the incidence of bacillary dysentery with a prediction model. We collected the annual and monthly laboratory data of confirmed cases from January 2004 to December 2014. In this study, we applied an autoregressive integrated moving average (ARIMA) model to forecast bacillary dysentery incidence in Jiangsu, China. The ARIMA (1, 1, 1) × (1, 1, 2)12 model fitted exactly with the number of cases during January 2004 to December 2014. The fitted model was then used to predict bacillary dysentery incidence during the period January to August 2015, and the number of cases fell within the model's CI for the predicted number of cases during January-August 2015. This study shows that the ARIMA model fits the fluctuations in bacillary dysentery frequency, and it can be used for future forecasting when applied to bacillary dysentery prevention and control. © 2016 APJPH.

Cardiovascular diseases (CVDs) are a leading cause of morbidity and mortality worldwide, necessitating major efforts in prevention. This review summarizes the currently available training opportunities in CVD prevention for fellows-in-training (FITs) and residents. We also highlight the challenges and future directions for CVD prevention as a field and propose a structure for an inclusive CVD prevention training program. At present, there is a lack of centralized training resources for FITs and residents interested in pursuing a career in CVD prevention. Training in CVD prevention is not an accredited subspecialty fellowship by the American Council of Graduate Medical Education (ACGME). Although there are several independent training programs under the broad umbrella of CVD prevention focusing on different aspects of prevention, there is no unified curriculum or training. More collaborative efforts are needed to identify CVD prevention as an ACGME-accredited subspecialty fellowship. Providing more resources can encourage and produce more leaders in this essential field.

Toward global prevention of sexually transmitted infections (STIs): the need for STI vaccines.

An estimated 499 million curable sexually transmitted infections (STIs; gonorrhea, chlamydia, syphilis, and trichomoniasis) occurred globally in 2008. In addition, well over 500 million people are estimated to have a viral STI such as herpes simplex virus type 2 (HSV-2) or human papillomavirus (HPV) at any point in time. STIs result in a large global burden of sexual, reproductive, and maternal-child health consequences, including genital symptoms, pregnancy complications, cancer, infertility, and enhanced HIV transmission, as well as important psychosocial consequences and financial costs. STI control strategies based primarily on behavioral primary prevention and STI case management have had clear successes, but gains have not been universal. Current STI control is hampered or threatened by several behavioral, biological, and implementation challenges, including a large proportion of asymptomatic infections, lack of feasible diagnostic tests globally, antimicrobial resistance, repeat infections, and barriers to intervention access, availability, and scale-up. Vaccines against HPV and hepatitis B virus offer a new paradigm for STI control. Challenges to existing STI prevention efforts provide important reasons for working toward additional STI vaccines. We summarize the global epidemiology of STIs and STI-associated complications, examine challenges to existing STI prevention efforts, and discuss the need for new STI vaccines for future prevention efforts.

Loss of control remains one of the largest contributors to aircraft fatal accidents worldwide. Aircraft loss-of-control accidents are highly complex in that they can result from numerous causal and contributing factors acting alone or (more often) in combination. Hence, there is no single intervention strategy to prevent these accidents. This paper presents future system concepts and research directions for preventing aircraft loss-of-control accidents.

This case-prevention of adolescent suicide-is one of a series of teaching cases in the Case-Based Series in Population-Oriented Prevention (C-POP). It has been developed for use in medical school and residency prevention curricula. The complete set of cases is presented in this supplement to the American Journal of Preventive Medicine. This teaching case examines the issue of prevention of adolescent and young adult suicide both at an individual and at a population or community level, using data from the Onondaga County Health Department. In the first section of the case, students are asked to determine whether five deaths related to falling or jumping at a local shopping mall should be considered to be suicidal deaths. Students then develop skills in the reporting as well as in the epidemiology of adolescent suicidal deaths in Onondaga County. As the case progresses, students analyze the results of a local surveillance study of suicidal attempts and ideation. The case concludes with students evaluating a hypothetical screening study intended to reduce the risk of suicidal death and discussing a research design to examine the effectiveness of this prevention strategy.

2010-01-15

Peritoneal carcinomatosis represents a devastating form of cancer progression with a very poor prognosis. Its complex pathogenesis is represented by a dynamic process comprising several steps. To the best of our knowledge pathogenesis can be partly explained by 3 major molecular pathways: (1) dissemination from the primary tumor; (2) primary tumor of peritoneum; and (3) independent origins of the primary tumor and peritoneal implants. These are not mutually exclusive and combinations of different mechanisms could occur inside a single case. There are still several aspects which need explanation by future studies. A comprehensive understanding of molecular events involved in peritoneal carcinomatosis is of paramount importance and should be systematically pursued not only to identify novel strategies for the prevention of the condition, but also to obtain therapeutic advances, through the identification of surrogate markers of prognosis and development of future molecular targeted therapies.

The Debate on Regulating Menthol Cigarettes: Closing a Dangerous Loophole vs Freedom of Choice

Dorfman, Lori; Daynard, Richard A.; Mejia, Pamela; Gottlieb, Mark

2014-01-01

The Family Smoking Prevention and Tobacco Control Act exempted menthol from a flavoring additive ban, tasking the Tobacco Products Safety Advisory Committee to advise on the scientific evidence on menthol. To inform future tobacco control efforts, we examined the public debate from 2008 to 2011 over the exemption. Health advocates regularly warned of menthol’s public health damages, but inconsistently invoked the health disparities borne by African American smokers. Tobacco industry spokespeople insisted that making menthol available put them on the side of African Americans’ struggle for justice and enlisted civil rights groups to help them make that case. In future debates, public health must prioritize and invest in the leadership of communities most affected by health harms to ensure a strong, unrelenting voice in support of health equity.

Current and future directions in the treatment and prevention of drug-induced liver injury: a systematic review

While the pace of discovery of new agents, mechanisms and risk factors involved in drug-induced liver injury (DILI) remains brisk, advances in the treatment of acute DILI seems slow by comparison. In general, the key to treating suspected DILI is to stop using the drug prior to developing irreversible liver failure. However, predicting when to stop is an inexact science, and commonly used ALT monitoring is an ineffective strategy outside of clinical trials. The only specific antidote for acute DILI remains N-acetylcysteine (NAC) for acetaminophen poisoning, although NAC is proving to be beneficial in some cases of non-acetaminophen DILI in adults. Corticosteroids can be effective for DILI associated with autoimmune or systemic hypersensitivity features. Ursodeoxycholic acid, silymarin and glycyrrhizin have been used to treat DILI for decades, but success remains anecdotal. Bile acid washout regimens using cholestyramine appear to be more evidenced based, in particular for lefluonomide toxicity. For drug-induced acute liver failure, the use of liver support systems is still investigational in the United States and emergency liver transplant remains limited by its availability. Primary prevention appears to be the key to avoiding DILI and the need for acute treatment. Pharmacogenomics, including HLA genotyping and the discovery of specific DILI biomarkers offers significant promise for the future. This article describes and summarizes the numerous and diverse treatment and prevention modalities that are currently available to manage DILI. PMID:26633044

Economic evaluation of preventive dental programs: what can they tell us?

2012-10-01

The role of public health program planners is to determine the effectiveness of public health programs, what recommendations should be made, what future initiatives should be taken, and what policies should be developed. At a basic level, to choose between competing alternatives, two characteristics of an intervention must be considered; these are its outcome and its cost. Based on cost and outcome, planners must select the option that offers the most advantages. Economic evaluation is commonly adopted by decision makers in the health sector to investigate the effectiveness of public health programs and to help plan future initiatives. Economic evaluation assists decision makers who must weigh the information it provides in the context of many and often competing options. In this way, an economic evaluation is an aid to decision making rather than the decision itself. Economic evaluation is becoming essential for informed decision making, with potential implications for public health policy and practice and for clinical practice too. While economic evaluations are commonly used in decision-making processes about health programs, few examples exist in the oral health literature. In the case of preventive oral health programs, economic analysis is often difficult, largely because it makes demands on epidemiological and demographic data that are hard to meet. This study will address the concepts and tools required to conduct economic evaluations of prevention programs. The emphasis will be on oral health and preventive dental programs, although the concepts presented could be useful for other public health programs by practitioners and managers with the aim of producing effective and efficient oral health programs. © 2012 John Wiley & Sons A/S.

Potential future impact of a partially effective HIV vaccine in a southern African setting.

It is important for public health and within the HIV vaccine development field to understand the potential population level impact of an HIV vaccine of partial efficacy--both in preventing infection and in reducing viral load in vaccinated individuals who become infected--in the context of a realistic future implementation scenario in resource limited settings. An individual level model of HIV transmission, progression and the effect of antiretroviral therapy was used to predict the outcome to 2060 of introduction in 2025 of a partially effective vaccine with various combinations of efficacy characteristics, in the context of continued ART roll-out in southern Africa. In the context of our base case epidemic (in 2015 HIV prevalence 28% and incidence 1.7 per 100 person years), a vaccine with only 30% preventative efficacy could make a substantial difference in the rate with which HIV incidence declines; the impact on incidence in relative terms is projected to increase over time, with a projected 67% lower HIV incidence in 2060 compared with no vaccine introduction. The projected mean decline in the general adult population death rate 2040-2060 is 11%. A vaccine with no prevention efficacy but which reduces viral load by 1 log is predicted to result in a modest (14%) reduction in HIV incidence and an 8% reduction in death rate in the general adult population (mean 2040-2060). These effects were broadly similar in multivariable uncertainty analysis. Introduction of a partially effective preventive HIV vaccine would make a substantial long-term impact on HIV epidemics in southern Africa, in addition to the effects of ART. Development of an HIV vaccine, even of relatively low apparent efficacy at the individual level, remains a critical global public health goal.

Young people and HIV prevention in Australian schools.

PubMed

Jones, Tiffany; Mitchell, Anne

2014-06-01

Australia has not seen a Human Immunodeficiency Virus (HIV) epidemic among young people. However, early research in the Australian context had indicated that the degree of unprotected sexual activity, partner change, and STI infection in this cohort would fuel a young people's epidemic if HIV ever reached a tipping point in the country. The difficulty of reaching young people outside school for HIV prevention has been no more successfully addressed in Australia than elsewhere. Therefore, the investment of Australian HIV prevention funds for youth has had an emphasis on school-based programs. This emphasis on formal schooling has led to a history of engagement with the ad hoc and unreliable nature of sexuality education in Australian schools. It has particularly been the catalyst for a struggle to construct young people as sexually active and as possessing a right to appropriate education, against tides of both secular and religiously-motivated resistance. The eight state and territory education sectors, along with the independent sectors, have had differing and sometimes troubled histories with HIV prevention. This paper discusses the differing HIV education policies and programs that have emerged in Australian schooling historically, and in some cases been abandoned altogether, amid strong public debates. It also considers current approaches, the new national curriculum, and future challenges. Additionally, the particular case of same sex attracted young men, who have a heightened level of vulnerability to HIV, is explored. Australian schools have struggled to address both the imperative for relevant sexuality education for same-sex-attracted young people and the broader issue of combating homophobia, which research has linked directly to this vulnerability.

Abstract Background: Travelers’ diarrhea causes significant morbidity including some sequelae, lost travel time and opportunity cost to both travelers and countries receiving travelers. Effective prevention and treatment are needed to reduce these negative impacts. Methods: This critical appraisal of the literature and expert consensus guideline development effort asked several key questions related to antibiotic and non-antibiotic prophylaxis and treatment, utility of available diagnostics, impact of multi-drug resistant (MDR) colonization associated with travel and travelers’ diarrhea, and how our understanding of the gastrointestinal microbiome should influence current practice and future research. Studies related to these key clinical areas were assessed for relevance and quality. Based on this critical appraisal, guidelines were developed and voted on using current standards for clinical guideline development methodology. Results: New definitions for severity of travelers’ diarrhea were developed. A total of 20 graded recommendations on the topics of prophylaxis, diagnosis, therapy and follow-up were developed. In addition, three non-graded consensus-based statements were adopted. Conclusions: Prevention and treatment of travelers’ diarrhea requires action at the provider, traveler and research community levels. Strong evidence supports the effectiveness of antimicrobial therapy in most cases of moderate to severe travelers’ diarrhea, while either increasing intake of fluids only or loperamide or bismuth subsalicylate may suffice for most cases of mild diarrhea. Further studies are needed to address knowledge gaps regarding optimal therapies, the individual, community and global health risks of MDR acquisition, manipulation of the microbiome in prevention and treatment and the utility of laboratory testing in returning travelers with persistent diarrhea.

Background Mosquito-borne diseases are climate sensitive and there has been increasing concern over the impact of climate change on future disease risk. This paper projected the potential future risk of Barmah Forest virus (BFV) disease under climate change scenarios in Queensland, Australia. Methods/Principal Findings We obtained data on notified BFV cases, climate (maximum and minimum temperature and rainfall), socio-economic and tidal conditions for current period 2000–2008 for coastal regions in Queensland. Grid-data on future climate projections for 2025, 2050 and 2100 were also obtained. Logistic regression models were built to forecast the otential risk of BFV disease distribution under existing climatic, socio-economic and tidal conditions. The model was applied to estimate the potential geographic distribution of BFV outbreaks under climate change scenarios. The predictive model had good model accuracy, sensitivity and specificity. Maps on potential risk of future BFV disease indicated that disease would vary significantly across coastal regions in Queensland by 2100 due to marked differences in future rainfall and temperature projections. Conclusions/Significance We conclude that the results of this study demonstrate that the future risk of BFV disease would vary across coastal regions in Queensland. These results may be helpful for public health decision making towards developing effective risk management strategies for BFV disease control and prevention programs in Queensland. PMID:23690959

Delta areas such as the Netherlands are more and more at risk of future flooding due to global climate change. Motivating residents living in flood-prone areas to effectively cope with local floods may lead to minimization of material losses and loss of life. The aim of this research was to investigate whether the extent to which residents had been exposed to flooding in the past was a key factor in motivating residents to effectively cope with future flooding. We also focused on the psychological variables that mediated this relationship. We conducted a survey (N = 516) among flood victims and nonvictims. We assessed subjective experiences due to past flooding, affective and cognitive appraisals, and coping responses. Results show that victims reported stronger emotions (negative and positive), and the receipt of more social support due to past flooding than did nonvictims. Moreover, victims worry more about future flooding, perceive themselves as more vulnerable to future flooding, perceive the consequences of future flooding as more severe, and have stronger intentions to take adaptive actions in the future than nonvictims. Structural equation modeling reveals that the latter effect was fully mediated by specific experiences and appraisals. Insights into factors and processes that have the potential to motivate residents to effectively cope with future floods may prove helpful in developing interventions to inform residents how to act effectively in case of an imminent flood.

We report the case of a patient with subtotal occlusion of the origin of the left common carotid artery (CCA) following thoracic graft placement. Retrograde endovascular placement of a stent-graft by minimal cervical access was undertaken to repair the occlusive lesion of the left CCA and prevent future complications of endoluminal thoracic reconstruction. The retrograde endovascular repair of CCA lesions, as other authors have already suggested, may be the treatment of choice in 'high-surgical-risk' patients.

Can Rheumatoid Arthritis Be Prevented?

Deane, Kevin

2013-01-01

The discovery of elevations of rheumatoid arthritis (RA)-related biomarkers prior to the onset of clinically apparent RA raises hopes that individuals who are at risk for future RA can be identified in a preclinical phase of disease that is defined as abnormalities of RA-related immune activity prior to the clinically apparent onset of joint disease. Additionally, there is a growing understanding of the immunologic processes that are occurring in preclinical RA, as well as a growing understanding of risk factors that may be mechanistically related to RA development. Furthermore, there are data supporting that treatment of early RA can lead to drug free remission. Taken as a whole, these findings suggest that it may be possible to use biomarkers and other factors to accurately identify the likelihood and timing of onset of future RA, and intervene with immunomodulatory therapies and/or risk factor modification to prevent the future onset of RA in at-risk individuals. Importantly, several clinical prevention trials for RA have already been tried, and one is underway. However, while our understanding of the growing understanding of the mechanisms and natural history of RA development may be leading us to the implementation of prevention strategies for RA, there are still several challenges to be met. These include developing sufficiently accurate methods of predicting those at high risk for future RA so that clinical trials can be developed based on accurate rates of development of arthritis and subjects can be adequately informed of their risk for disease, identifying the appropriate interventions and biologic targets for optimal prevention, and addressing the psychosocial and economic aspects that are crucial to developing broadly applicable prevention measures for RA. These issues notwithstanding, prevention of RA may be within reach in the near future. PMID:24315049

Litigation and alcohol policy: lessons from the US Tobacco Wars.

This paper explores the role of litigation in preventing alcohol-related harms, identifying lessons from the use of litigation in tobacco control policy in the United States. It analyzes the key components of litigation in an international context, provides a case study of its potential use in addressing the marketing of alcopops to youth and offers recommendations for pursuing litigation strategies in future alcohol policy efforts. The paper's analyses are based on both original and secondary legal research. State and federal case law and secondary sources are reviewed in assessing lessons learned from tobacco litigation in the United States and the potential role of litigation in alcohol policy, both in the United States and internationally. Assessment of alcohol litigation cases and state and federal laws and regulations provides the foundation for the alcopops case study. The tobacco litigation experience demonstrates that litigation is a powerful tool in addressing aggressive marketing by purveyors of addictive products such as alcohol. To be effective at both national and international levels, litigation should encompass a broad array of legal tactics designed to identify and restrict unfair, deceptive and misleading alcohol marketing tactics and should be utilized in conjunction with complementary prevention strategies. Research conducted on the impact of alcohol marketing on youth alcohol consumption and problems is needed to support potential litigation claims. Developing litigation expertise within the alcohol policy field and building collaboration with litigation specialists in tobacco control should also be considered a high priority.

Objective: To characterize the presentation of burns in children and risk factors associated with their occurrence in a developing country as a basis for future prevention programs. Design: Case-control study. Setting: Burn unit of the National Institute of Child Health (Instituto Nacional de Salud del Niño) in Lima, Peru. Methods: A questionnaire was administered to all consenting guardians of children admitted to the burns (cases) and general medicine (controls) units during a period of 14 months. Guardians of patients were questioned regarding etiology of the injury, demographic and socioeconomic data. Results: 740 cases and controls were enrolled. Altogether 77.5% of the cases burns occurred in the patient's home, with 67.8% in the kitchen; 74% were due to scalding. Most involved children younger than 5 years. Lack of water supply (odds ratio (OR) 5.2, 95% confidence interval (CI) 2.1 to 12.3), low income (OR 2.8, 95% CI 2.0 to 3.9), and crowding (OR 2.5, 95%CI 1.7 to 3.6) were associated with an increased risk. The presence of a living room (OR 0.6, 95% CI 0.4 to 0.8) and better maternal education (OR 0.6, 95% CI 0.5 to 0.9) were protective factors. Conclusions: To prevent burns interventions should be directed to low socioeconomic status groups; these interventions should be designed accordingly to local risk factors. PMID:11928972

In response to the emergence of severe acute respiratory syndrome (SARS), the United States established national surveillance using a sensitive case definition incorporating clinical, epidemiologic, and laboratory criteria. Of 1,460 unexplained respiratory illnesses reported by state and local health departments to the Centers for Disease Control and Prevention from March 17 to July 30, 2003, a total of 398 (27%) met clinical and epidemiologic SARS case criteria. Of these, 72 (18%) were probable cases with radiographic evidence of pneumonia. Eight (2%) were laboratory-confirmed SARS-coronavirus (SARS-CoV) infections, 206 (52%) were SARS-CoV negative, and 184 (46%) had undetermined SARS-CoV status because of missing convalescent-phase serum specimens. Thirty-one percent (124/398) of case-patients were hospitalized; none died. Travel was the most common epidemiologic link (329/398, 83%), and mainland China was the affected area most commonly visited. One case of possible household transmission was reported, and no laboratory-confirmed infections occurred among healthcare workers. Successes and limitations of this emergency surveillance can guide preparations for future outbreaks of SARS or respiratory diseases of unknown etiology. PMID:15030681

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.

The chikungunya virus (CHIKV) epidemic in the Americas is of significant public health importance due to the lack of effective control and prevention strategies, severe disease morbidity among susceptible populations, and potential for persistent arthralgia and long-term impaired physical functionality. Using surveillance data of suspected CHIKV cases, we describe the first reported outbreak in the U.S. Virgin Islands. CHIKV incidence was highest among individuals aged 55–64 years (13.1 cases per 1,000 population) and lowest among individuals aged 0–14 years (1.8 cases per 1,000 population). Incidence was higher among women compared to men (6.6 and 5.0 cases per 1,000 population, respectively). More than half of reported laboratory-positive cases experienced fever lasting 2–7 days, chills/rigor, myalgia, anorexia, and headache. No clinical symptoms apart from the suspected case definition of fever ≥ 38°C and arthralgia were significantly associated with being a reported laboratory-positive case. These results contribute to our knowledge of demographic risk factors and clinical manifestations of CHIKV disease and may aid in mitigating future CHIKV outbreaks in the Caribbean. PMID:27402523

Ever since the Fukushima Daiichi nuclear power plant (NPP) accident, every day about 3,000 workers have been working to repair the situation. The frequent occurrence of heat disorders has been a concern for the workers wearing protective clothing with poor ventilation. We have been analyzing the heat disorder problem since the accident in order to come up with a solution to prevent future heat disorder incidents among Fukushima Daiichi NPP accident clean-up workers. From March 22 to September 16, 2011, the Fukushima Labor Bureau assessed 43 cases of nuclear power plant workers with heat disorders. Age of subject, month and time of occurrence, temperature, and humidity were examined for each case, as well as the severity of heat disorders. The grade of severity was divided into Grade I and Grade II or higher. Then, age, temperature, and humidity were analyzed using the Mann-Whitney Utest, and age, temperature, humidity, and presence or absence of a cool-vest were analyzed using the χ(2) test and logistic regression analysis. SPSS version 17.0 statistical software was used with a level of significance of p< 0.05. Heat disorders occurred most frequently in subjects in their 40s (30.2%), followed by those in their 30s (25.6%), mostly in July (46.5%) between 7 am and 12 pm (69.8%). Heat disorders occurred most frequently in environments with temperatures more than 25°C (76.7%) and humidity of 70-80% (39.5%). Heat disorders of Grade II or higher occurred in 10 cases, 5 of which were in June. According to statistical analysis, there were no significant differences in difference of severity for all factors. Heat disorders usually occur in workers aged 45-60; however, cases of heat disorders at the Fukushima Daiichi NPP occurred in clean-up workers at the relatively younger ages of 30-40, suggesting the need for heat disorder prevention measures for these younger workers. Heat disorder cases primarily occurred in the morning, necessitating preventive measures for the early hours of the day. In addition, because heat disorders of Grade II or higher occurred in June in 5 of 10 cases, we believe heat disorder precautions should be implemented from June. The lack of significant difference in severity difference may be attributable to the small number of cases or other factors. We think Fukushima Daiichi NPP accident clean-up workers need heat disorder prevention measures for their safety, based on the results of this study.

Spring viraemia of carp (SVC) is a disease of international importance that predominantly affects cyprinid fish and can cause significant mortality. In the United Kingdom (UK), SVC was first detected in 1977 with further cases occurring in fisheries, farms, wholesale and retail establishments throughout England and Wales (but not Scotland, where few cyprinid populations exist, nor Northern Ireland where SVC has never been detected) over the subsequent 30 years. Following a control and eradication programme for the disease initiated in 2005, the UK was recognised free of the disease in 2010. This study compiles historic records of SVC cases in England and Wales with a view to understanding its routes of introduction and spread, and assessing the effectiveness of the control and eradication programme in order to improve contingency plans to prevent and control future disease incursions in the cyprinid fish sectors. Between 1977 and 2010 the presence of SVC was confirmed on 108 occasions, with 65 of the cases occurring in sport fisheries and the majority of the remainder occurring in the ornamental fish sector. The study found that throughout the history of SVC in the UK, though cases were widely distributed, their occurrence was sporadic and the virus did not become endemic. All evidence indicates that SVC was not able to persist under UK environmental conditions, suggesting that the majority of cases were a result of new introductions to the UK as opposed to within-country spread. The control and eradication programme adopted in 2005 was highly effective and two years after its implementation cases of SVC ceased. Given the non-persistent nature of the pathogen the most important aspect of the control programme focused on preventing re-introduction of the virus to the UK. Despite the effectiveness of these controls against SVC, this approach is likely to be less effective against more persistent pathogens such as koi herpesvirus, which are likely to require more stringent measures to prevent within-country spread.

The current study aims to assess the preventability of the contrast media adverse drug reactions reported through the Campania spontaneous reporting system, identifying the possible limitations emerged in this type of evaluation. All the individual case safety reports validated by the Campania Pharmacovigilance Regional Centre from July 2012 to September 2015 were screened to select those that reported contrast media as suspected drug. Campania Preventability Assessment Committee, in collaboration with clinicians specialized in Radiology, assessed the preventability according to the P-Method, through a case-by-case approach. From July 2012 to September 2015, 13798 cases were inserted by pharmacovigilance managers in the Italian Pharmacovigilance Network database (in the geographical contest of the Campania Region), of which 67 reported contrast media as suspected drug. Five preventable cases were found. The most reported causes for preventability were the inappropriate drug use for the case clinical conditions and the absence of the preventive measure administrated prior to the contrast media administration. Several limitations were found in the evaluation of the critical criteria for the preventability assessment. Educational initiatives will be organized directly to the healthcare professionals involved in the contrast media administration, to promote an appropriate use of the contrast media.

Chinese herbs nephropathy is known as a subacute interstitial nephritis attributed to aristolochic acid. This work describes the case of a 49-year-old male who displayed subacute renal failure induced by ingestion of herbal powder containing Xi Xin, which includes aristolochic acid. Since Xi Xin is a common ingredient in traditional formulae, care needs to be taken in the future to identify the aristolochic acid concentration of different components of Xi Xin. Xi Xin containing aristolochic acid should be forbidden for use in remedies in order to prevent the harmful effects of aristolochic acid.

Loss of control remains one of the largest contributors to fatal aircraft accidents worldwide. Aircraft loss-of-control accidents are complex in that they can result from numerous causal and contributing factors acting alone or (more often) in combination. Hence, there is no single intervention strategy to prevent these accidents. To gain a better understanding into aircraft loss-of-control events and possible intervention strategies, this paper presents a detailed analysis of loss-of-control accident data (predominantly from Part 121), including worst case combinations of causal and contributing factors and their sequencing. Future potential risks are also considered.

Most people with diabetes suffer some deterioration of the feet. Diabetic foot syndrome causes ulceration in about 15% of cases and such deterioration leads to amputation in about 2.5% of diabetic patients, diminishing their quality of life and generating extraordinary costs for patients and public health systems. Currently, there is no objective method for the detection of diabetic foot syndrome in its early stages. We propose terahertz imaging as a method for the evaluation of such deterioration. This screening method could aid the prevention and medical treatment of this condition in the future.

Epidemiology of dengue: past, present and future prospects

Murray, Natasha Evelyn Anne; Quam, Mikkel B; Wilder-Smith, Annelies

2013-01-01

Dengue is currently regarded globally as the most important mosquito-borne viral disease. A history of symptoms compatible with dengue can be traced back to the Chin Dynasty of 265–420 AD. The virus and its vectors have now become widely distributed throughout tropical and subtropical regions of the world, particularly over the last half-century. Significant geographic expansion has been coupled with rapid increases in incident cases, epidemics, and hyperendemicity, leading to the more severe forms of dengue. Transmission of dengue is now present in every World Health Organization (WHO) region of the world and more than 125 countries are known to be dengue endemic. The true impact of dengue globally is difficult to ascertain due to factors such as inadequate disease surveillance, misdiagnosis, and low levels of reporting. Currently available data likely grossly underestimates the social, economic, and disease burden. Estimates of the global incidence of dengue infections per year have ranged between 50 million and 200 million; however, recent estimates using cartographic approaches suggest this number is closer to almost 400 million. The expansion of dengue is expected to increase due to factors such as the modern dynamics of climate change, globalization, travel, trade, socioeconomics, settlement and also viral evolution. No vaccine or specific antiviral therapy currently exists to address the growing threat of dengue. Prompt case detection and appropriate clinical management can reduce the mortality from severe dengue. Effective vector control is the mainstay of dengue prevention and control. Surveillance and improved reporting of dengue cases is also essential to gauge the true global situation as indicated in the objectives of the WHO Global Strategy for Dengue Prevention and Control, 2012–2020. More accurate data will inform the prioritization of research, health policy, and financial resources toward reducing this poorly controlled disease. The objective of this paper is to review historical and current epidemiology of dengue worldwide and, additionally, reflect on some potential reasons for expansion of dengue into the future.

The Role of Text Messaging in Cardiovascular Risk Factor Optimization.

Klimis, Harry; Khan, Mohammad Ehsan; Kok, Cindy; Chow, Clara K

2017-01-01

Many cases of CVD may be avoidable through lowering behavioural risk factors such as smoking and physical inactivity. Mobile health (mHealth) provides a novel opportunity to deliver cardiovascular prevention programs in a format that is potentially scalable. Here, we provide an overview of text messaging-based mHealth interventions in cardiovascular prevention. Text messaging-based interventions appear effective on a range of behavioural risk factors and can effect change on multiple risk factors-e.g. smoking, weight, blood pressure-simultaneously. For many texting studies, there are challenges in interpretation as many texting interventions are part of larger complex interventions making it difficult to determine the benefits of the separate components. Whilst there is evidence for text messaging improving cardiovascular risk factor levels in the short-term, future studies are needed to examine the durability of these effects and whether they can be translated to improvements in clinical care and outcomes.

Does culture matter?: a cross-national investigation of women's responses to cancer prevention campaigns.

Han, Kyoo-Hoon; Jo, Samsup

2012-01-01

We examined how culture influences the persuasive effects of health campaigns that promote early screening for cancers that occur in women. Two message dimensions were included: individualistic vs. collectivistic appeal and gain vs. loss frame. A total of 955 females from three countries-the United States, South Korea, and Japan-participated in the experiment. From the results, we found that message framing alone did not significantly influence the effectiveness of public campaigns for women's cancer prevention; and this tendency was similar across the three countries. Gain-framed messages are likely to be more persuasive when combined with a collectivistic appeal, however, whereas loss-framed messages tend to be more effective when combined with an individualistic appeal in both the United States and South Korea; but this result was not the case for Japan. Based on the findings, we suggested theoretical and managerial implications as well as several directions for future research.

Household furniture tip-over deaths of young children.

2011-07-01

The potential for the injury or death of a child resulting from the tip-over of a piece of household furniture or a domestic appliance has not been previously well recognized. We reviewed nine accidental deaths of young children that resulted from avoidable residential hazards and/or lapses in supervision of the children by their caregivers. The offending household items included televisions, bedroom dressers, a kitchen stove, and a lounge chair. The causes of death were mechanical asphyxia, blunt trauma, and combined blunt head trauma and asphyxia. All of the deaths could have been prevented by appropriate anchoring of the piece of furniture and/or closer supervision of the child. A thorough multidisciplinary investigation is essential in establishing the cause and manner of death in such cases and in identifying risk factors that may aid in the prevention of future childhood deaths. © 2011 American Academy of Forensic Sciences.

Home Environmental Interventions for the Prevention or Control of Allergic and Respiratory Diseases: What Really Works.

Le Cann, Pierre; Paulus, Hélène; Glorennec, Philippe; Le Bot, Barbara; Frain, Sophie; Gangneux, Jean Pierre

Home health care workers interventions have been implemented in western countries to improve health status of patients with respiratory diseases especially asthma and allergic illnesses. Twenty-six controlled studies dealing with prevention and control of these diseases through home environmental interventions were reviewed. After a comprehensive description of the characteristics of these studies, the effectiveness of each intervention was then evaluated in terms of participants' compliance with the intervention program, improvement of quality of the indoor environment, and finally improvement of health outcomes, in detailed tables. Limitations and biases of the studies are also discussed. Overall, this review aims at giving a toolbox for home health care workers to target the most appropriate measures to improve health status of the patient depending on his and/or her environment and disease. Only a case-by-case approach with achievable measures will warrant the efficacy of home interventions. This review will also provide to the research community a tool to better identify targets to focus in future evaluation studies of home health care workers action.

Avahan, a large-scale HIV prevention program in India, transitioned over 130 intervention sites from donor funding and management to government ownership in three rounds. This paper examines the transition experience from the perspective of the communities targeted by these interventions. Fifteen qualitative longitudinal case studies were conducted across all three rounds of transition, including 83 in-depth interviews and 45 focus group discussions. Data collection took place between 2010 and 2013 in four states: Andhra Pradesh, Karnataka, Maharashtra and Tamil Nadu. We find that communication about transition was difficult at first but improved over time, while issues related to employment of peer educators were challenging throughout the transition. Clinical services were shifted to government providers resulting in mixed experiences depending on the population being targeted. Lastly, the loss of activities aimed at community ownership and mobilization negatively affected the beneficiaries' view of transition. While some programmatic changes resulted in improvements, additional opportunity costs for beneficiaries may pose barriers to accessing HIV prevention services. Communicating and engaging community stakeholders early on in future such transitions may mitigate negative feelings and lead to more constructive relationships and dialogue.

Pneumocystis jirovecii Pneumonia in Rheumatoid Arthritis Patients: Risks and Prophylaxis Recommendations

PubMed Central

Mori, Shunsuke; Sugimoto, Mineharu

2015-01-01

Pneumocystis jirovecii infection causes fulminant interstitial pneumonia (Pneumocystis pneumonia, PCP) in patients with rheumatoid arthritis (RA) who are receiving biological and/or nonbiological antirheumatic drugs. Recently, we encountered a PCP outbreak among RA outpatients at our institution. Hospital-acquired, person-to-person transmission appears to be the most likely mode of this cluster of P. jirovecii infection. Carriage of P. jirovecii seems a time-limited phenomenon in immunocompetent hosts, but in RA patients receiving antirheumatic therapy, clearance of this organism from the lungs is delayed. Carriers among RA patients can serve as sources and reservoirs of P. jirovecii infection for other susceptible patients in outpatient facilities. Development of PCP is a matter of time in such carriers. Considering the poor survival rates of PCP cases, prophylactic antibiotics should be considered for RA patients who are scheduled to receive antirheumatic therapy. Once a new case of PCP occurs, we should take prompt action not only to treat the PCP patient but also to prevent other patients from becoming new carriers of P. jirovecii. Short-term prophylaxis with trimethoprim-sulfamethoxazole is effective in controlling P. jirovecii infection and preventing future outbreaks of PCP among RA patients. PMID:26396551

The ARIMA (0,1,0)(1,1,1)12 model (AICc = 1342.2 BIC = 1350.3) was selected as the best performing ARIMA model and the ETS (M,N,M) model (AICc = 1678.6, BIC = 1715.4) was selected as the best performing ETS model, and the ETS (M,N,M) model with the minimum RMSE was finally selected for in-sample-simulation and out-of-sample forecasting. Descriptive statistics showed that the reported number of pertussis cases by China CDC increased by 66.20% from 2005 (4058 cases) to 2015 (6744 cases). According to Hodrick-Prescott filter, there was an apparent cyclicity and seasonality in the pertussis reports. In out of sample forecasting, the model forecasted a relatively high incidence cases in 2016, which predicates an increasing risk of ongoing pertussis resurgence in the near future. In this regard, the ETS model would be a useful tool in simulating and forecasting the incidence of pertussis, and helping decision makers to take efficient decisions based on the advanced warning of disease incidence.

[Maternal filicide in Japan: analyses of 96 cases and future directions for prevention].

Maternal filicide is not an isolated phenomenon. When a mother kills her child, she may be affected by many factors and confronted with different problems based on the child's developmental stage. In this study in Japan, a judicial sample of 96 adult women, convicted in their first trial for the murder or attempted murder of their children, was divided into four groups of mothers according to the age of the victim (25 women killed neonates, 22 women infants, 27 women preschool children, and 22 women schoolchildren and/or teenagers) in order to identify the factors that have a major impact on filicide in each group. The socio-demographic, clinical, forensic, circumstantial, and offense characteristics, and legal disposition of 96 cases drawn from judicial records were compared among the four groups using the Kruskal-Wallis test; comparison of two groups was conducted using the Mann-Whitney test. Neonaticide cases were distinguished from the other three groups by marked differences: a significantly higher rate of unmarried mothers, financial difficulties, absence of mental illness, and admission of not wanting an illegitimate child. In the other groups, mental disorders were frequent; in particular, post-partum depression was the primary cause of infanticide. For the two groups of cases involving a child older than one year, filicidal mothers were more affected by circumstantial factors such as health problems of the child or severe marital discord. These problems may then have caused a reactive mental disorder among these mothers. The risk of fatal abuse or neglect was higher for handicapped preschool children. Filicide-suicide was most frequently seen among school-aged children and/or teenagers who had serious behavioral problems, and these children often had a mental disorder. The classification of maternal filicide by age of the child demonstrated that there are specific issues for each group. Based on these findings, future directions for prevention include: appropriate sex education for youths to avoid unwanted pregnancy; organization of specialized mental health services for mothers with post-partum mental disorder; careful psychiatric risk assessment of mentally ill mothers; and development of diversified social support measures for child-bearing parents, especially those with identifiable financial or social difficulties.

In considering the role of the cancer prevention workforce in meeting the nation's future health care needs, it is vital to address the considerable gaps in information, communication, training, professional development, roles, and levels of collaboration among diverse disciplines, stakeholders, and constituencies. As part of an October 2009 symposium at The University of Texas MD Anderson Cancer Center entitled "Future Directions in Cancer Prevention and Control: Workforce Implications for Training, Practice, and Policy," the Health Policy and Advocacy Working Group was convened to discuss barriers to closing these gaps. Three major themes emerged from the group's deliberations and are discussed here: (1) the role of critical health literacy and evidence-based collaborations in cancer prevention education, research, and practice; (2) the implications of health advocacy for policy development and clinical and public health practice; and (3) culturally and linguistically appropriate cancer prevention programs and information within advocacy/workforce collaborations. Mechanisms for addressing these gaps are presented.

The failure by the city of Flint, Michigan to properly treat its municipal water system after a change in the source of water, has resulted in elevated lead levels in the city’s water and an increase in city children’s blood lead levels. Lead exposure in young children can lead to decrements in intelligence, development, behavior, attention and other neurological functions. This lack of ability to provide safe drinking water represents a failure to protect the public’s health at various governmental levels. This article describes how the tragedy happened, how low-income and minority populations are at particularly high risk for lead exposure and environmental injustice, and ways that we can move forward to prevent childhood lead exposure and lead poisoning, as well as prevent future Flint-like exposure events from occurring. Control of the manufacture and use of toxic chemicals to prevent adverse exposure to these substances is also discussed. Environmental injustice occurred throughout the Flint water contamination incident and there are lessons we can all learn from this debacle to move forward in promoting environmental justice.

2014-12-01

Treatment as prevention is expected to have a major role in reducing HIV incidence, but other prevention interventions will also be required to bring the epidemic under control, particularly among key populations. One or more forms of pre-exposure prophylaxis (PrEP) will likely play a critical role. Oral PrEP with emtricitabine-tenofovir (Truvada®) is currently available in the US and some other countries, but uptake has been slow. We review the concerns that have contributed to this slow uptake and discuss current and future research in this critical area of HIV prevention research.

Background Previous research demonstrated efficacy of a brief behavioral intervention to reduce incidence of HIV and sexually transmitted infections (STIs) among female sex workers (FSWs) in Tijuana and Ciudad Juarez, Mexico, cities on Mexico's border with the US. We assessed this intervention's cost-effectiveness. Methodology and Principal Findings A life-time Markov model was developed to estimate HIV cases prevented, changes in quality-adjusted life expectancy (QALE), and costs per additional quality-adjusted life year gained (QALY), comparing (in US$2,009) no intervention to a once-only and annual intervention. Future costs and health benefits were discounted annually at 3%. Sensitivity analyses evaluated model robustness. We found that for a hypothetical 1,000 FSWs receiving the once-only intervention, there were 33 HIV cases prevented and 5.7 months of QALE gained compared to no intervention. The additional cost per QALY gained was US$183. For FSWs receiving the intervention annually, there were 29 additional HIV cases prevented and 4.5 additional months of QALE compared to the once-only intervention. The additional cost per QALY was US$1,075. When highly active antiretroviral therapy (HAART) was included in the model, the annual intervention strategy resulted in net savings and dominated both once-only and no intervention strategies, and remained robust across extensive sensitivity analyses. Even when considering clinical benefits from HAART, ignoring added costs, the cost per QALY gained remained below three times the Mexican GDP per capita, and below established cost-effectiveness thresholds. Conclusions/Significance This brief intervention was shown to be cost-effective among FSWs in two Mexico-US border cities and may have application for FSWs in other resource-limited settings.

We conducted the first pilot Italian study to assess the preventability of adverse drug reactions involving psychotropic drugs reported through spontaneous reporting system from 01/07/2012 to 31/12/2014 in Campania Region. Preventability was assessed, case-by-case, using an adapted version of the P-method. The evaluation was performed only for those reports that had, as suspected drug, antipsychotics, mood stabilizers, antidepressants, anxiolytic and/or sedative-hypnotic. Eighty-one cases (19.2%) out of 421 reported during the study period were preventable. In seventy-seven (95.1%) out of 81 preventable cases, the underlying mechanism of the adverse drug reactions was dose-related, in four (4.9%) preventable cases the underlying mechanism of the adverse drug reactions was respectively susceptibility- (1; 1.2%), unknown- (1; 1.2%) and time-related (2; 2.5%). In the 81 preventable cases, 97 critical criteria were detected of which 29/97 (29.9%) related to healthcare professionals' practices, 0/97 (0.0%) to drug quality and 68/97 (70.1%) to patient behaviour. We proved that it was possible to apply and adapt the P-Method to assess the preventability of the adverse drug reactions involving psychotropic drugs, analysing individual case safety report sent through Campania Region spontaneous reporting system. Information acquired will be used to organize educational activities for both physicians and patients to promote a more appropriate drug use.

Preventing Rapid Repeat Births Among Latina Adolescents: The Role of Parents

2012-01-01

Latina adolescent parents are at increased risk for rapid repeat births (second birth ≤ 24 months after the first), sexually transmitted infections, and negative educational and social outcomes. Although several effective parent-based interventions have been developed to prevent Latino youths’ sexual risk taking, little research has explored the development of interventions to prevent repeat births that involve the parents of these adolescents. Existing preventative interventions involving parents suffer from important methodological limitations. Additional research is needed to advance theories of behavior, identify the causal pathways of parental influence, and specify appropriate behavioral targets. Future parent-based interventions to prevent repeat births should target pregnancy intentions, age of partners, contraceptive use, integrated prevention of pregnancies and sexually transmitted infections, educational attainment, and future orientations.

Pervasive healthcare: paving the way for a pervasive, user-centered and preventive healthcare model.

Arnrich, B; Mayora, O; Bardram, J; Tröster, G

2010-01-01

The aging of the population creates pressure on the healthcare systems in various ways. A massive increase of chronic disease conditions and age-related illness are predicted as the dominant forces driving the future health care. The objective of this paper is to present future research demands in pervasive healthcare with the goal to meet the healthcare challenges by paving the way for a pervasive, user-centered and preventive healthcare model. This paper presents recent methodological approaches and proposes future research topics in three areas: i) pervasive, continuous and reliable long-term monitoring systems; ii) prevention through pervasive technology as a key element to maintain lifelong wellness; and iii) design and evaluation methods for ubiquitous, patient-centric technologies. Pervasive technology has been identified as a strong asset for achieving the vision of user-centered preventive healthcare. In order to make this vision a reality, new strategies for design, development and evaluation of technology have to find a common denominator and consequently interoperate. Moreover, the potential of pervasive healthcare technologies offers new opportunities beyond traditional disease treatment and may play a major role in prevention, e.g. motivate healthy behavior and disease prevention throughout all stages of life. In this sense, open challenges in future research have to be addressed such as the variability of health indicators between individuals and the manner in which relevant health indicators are provided to the users in order to maximize their motivation to mitigate or prevent unhealthy behaviors. Additionally, collecting evidence that pervasive technology improves health is seen as one of the toughest challenges. Promising approaches are recently introduced, such as "clinical proof-of-concept" and balanced observational studies. The paper concludes that pervasive healthcare will enable a paradigm shift from the established centralized healthcare model to a pervasive, user-centered and preventive overall lifestyle health management. In order to provide these new opportunities everywhere, anytime and to anyone, future research in the fields of pervasive sensing, pervasive prevention and evaluation of pervasive technology is inevitably needed.

[Monogenic and syndromic symptoms of morbid obesity. Rare but important].

PubMed

Wiegand, S; Krude, H

2015-02-01

Monogenic and syndromic obesity are rare diseases with variable manifestation. Therefore diagnosis is difficult and often delayed. The purpose of this work was to develop a clinical diagnostic algorithm for earlier diagnosis. Available publications for clinical symptoms and molecular defects of monogenic and syndromic obesity cases were evaluated. Monogenic and syndromic obesity can be expected in cases with early manifestation before the age of 5 years and a BMI above 40 or above the 99th percentile. Syndromic cases are mostly associated with a low IQ and dwarfism. Monogenic cases are associated with additional endocrine defects. Measurement of serum leptin proves the treatable leptin deficiency. Sequencing of the melanocortin-4 receptor gene (MC4R) allows diagnosis of the most frequent monogenic form of obesity. Treatment with a melanocyte-stimulating hormone (MSH) analog can be expected in the future. Early treatment of children with Prader-Willi syndrome can prevent severe obesity. Because in some cases treatment is available, monogenic and syndromic obesity should be diagnosed early. Based on the disease symptoms, serum leptin, and MC4R sequencing, a diagnostic algorithm is proposed, which can be used to diagnose cases of morbid obesity.

Tuberculous meningitis causes substantial mortality and morbidity in children and adults. More research is urgently needed to better understand the pathogenesis of disease and to improve its clinical management and outcome. A major stumbling block is the absence of standardised diagnostic criteria. The different case definitions used in various studies makes comparison of research findings difficult, prevents the best use of existing data, and limits the management of disease. To address this problem, a 3-day tuberculous meningitis workshop took place in Cape Town, South Africa, and was attended by 41 international participants experienced in the research or management of tuberculous meningitis. During the meeting, diagnostic criteria were assessed and discussed, after which a writing committee was appointed to finalise a consensus case definition for tuberculous meningitis for use in future clinical research. We present the consensus case definition together with the rationale behind the recommendations. This case definition is applicable irrespective of the patient's age, HIV infection status, or the resources available in the research setting. Consistent use of the proposed case definition will aid comparison of studies, improve scientific communication, and ultimately improve care. Copyright © 2010 Elsevier Ltd. All rights reserved.

In Thailand, five cancer types—breast, cervical, colorectal, liver and lung cancer—contribute to over half of the cancer burden. The magnitude of these cancers must be quantified over time to assess previous health policies and highlight future trajectories for targeted prevention efforts. We provide a comprehensive assessment of these five cancers nationally and subnationally, with trend analysis, projections, and number of cases expected for the year 2025 using cancer registry data. We found that breast (average annual percent change (AAPC): 3.1%) and colorectal cancer (female AAPC: 3.3%, male AAPC: 4.1%) are increasing while cervical cancer (AAPC: −4.4%) is decreasing nationwide. However, liver and lung cancers exhibit disproportionately higher burdens in the northeast and north regions, respectively. Lung cancer increased significantly in northeastern and southern women, despite low smoking rates. Liver cancers are expected to increase in the northern males and females. Liver cancer increased in the south, despite the absence of the liver fluke, a known factor, in this region. Our findings are presented in the context of health policy, population dynamics and serve to provide evidence for future prevention strategies. Our subnational estimates provide a basis for understanding variations in region-specific risk factor profiles that contribute to incidence trends over time. PMID:28817104

Current and future trends in the prevention, treatment and control of rabies.

PubMed

Rupprecht, Charles E; Willoughby, Rodney; Slate, Dennis

2006-12-01

Rabies remains a global zoonosis of major public health, agricultural and economic significance. Dogs are the major animal reservoirs in developing regions, wildlife maintain cycles of infection even in developed countries and new viral etiological agents continue to emerge. Nearly all human rabies cases are related directly to animal bite and thus, primary disease prevention requires minimization of suspected exposures. Once exposure occurs, modern prophylaxis entails immediate wound care, local infiltration of rabies immune globulin and parenteral administration of modern cell culture vaccines in multiple doses. Pre-exposure vaccination should occur in selected population groups at risk of occupational exposure. Historically, survival from fatal rabies by at least five human patients, vaccinated prior to the onset of clinical signs, signaled initial optimism as to the theoretical utility of medical intervention. Recently, the heroic recovery of an unvaccinated teenager from clinical rabies offers hope of future specific therapy. Canine rabies elimination is the key towards ultimate reduction of the disease burden, as first illustrated in developed countries. Implementation of oral vaccination in free-ranging carnivore hosts demonstrates the feasibility of disease abatement in particular wildlife populations, such as demonstrated in Europe and North America, with an enhanced need for application to developing countries in the Americas, Africa and Eurasia.

Mothers with HIP - the short term and long-term impact, what is new?

Hyperglycemia is one of the most common medical conditions that women encounter during pregnancy and it is due to gestational diabetes (GDM) in the majority of cases [1]. GDM is associated with a higher incidence of maternal morbidity in pregnancy in term of hypertensive disorders/preclampsia and higher rate of cesarean delivery but also with long-term risk of type 2 diabetes and cardiovascular disease. Pregnancy can therefore be considered a stress test; diagnosis of HIP can unmask a preexisting susceptibility and consequently a future risk for type 2 diabetes and can be a useful marker of future cardiovascular risk. Postpartum follow up provides an excellent opportunity to implement healthy lifestyle behaviors to prevent or delay the development of diabetes or cardiovascular disease. The aim of the current review is to focus on short and long term maternal morbidity of HIP. Copyright © 2018. Published by Elsevier B.V.

From hydraulic fracturing to climate change to seismic risk, government science and scientists are integral to public decision making in the geosciences. Following calls for increased scientific integrity across the government, policies have been put in place in recent years to be promote transparency and appropriate use of science in government decision making. But how effective have these initiatives been? With the development of scientific integrity policies, new transparency measures, and other efforts in recent years, are we seeing improvements in how federal agencies use science? And importantly, can these safeguards prevent potential future breaches of scientific integrity and misuse science for political gain? Review of recent progress and problems around government scientific integrity, including case studies, policy assessments, and surveys of federal scientists, can shed light on how far the we have come and what areas still need improvement to ensure that government scientific integrity is preserved in the future.

In the last decade, more and more medicine students are involved in research, either in the form of a research project within specialized courses or as a scientific article to be presented at student international conferences or published in prestigious medical journals. The present study included 250 2nd year medical students, currently studying within the University of Medicine and Pharmacy of Craiova, Romania. There were collected 239 responses, with a response rate of 95.6%. In our study, the results showed that foreign students within the University of Medicine and Pharmacy of Craiova did have some issues understanding plagiarism with fewer foreign students (34%) than Romanian students (66%) recognizing that simply changing words does not avoid plagiarism. In our opinion, there should be put more emphasis upon plagiarism implications and its aspects, as well, with a permanent order to try to prevent future attempts of plagiarizing among medical students as future researchers within the medical science field.

Highlights: Black-Right-Pointing-Pointer We model waste prevention behaviour using structure equation modelling. Black-Right-Pointing-Pointer We merge attitude-behaviour theories with wider models from environmental psychology. Black-Right-Pointing-Pointer Personal norms and perceived behaviour control are the main behaviour predictors. Black-Right-Pointing-Pointer Environmental concern, moral obligation and inconvenience are the main influence on the behaviour. Black-Right-Pointing-Pointer Waste prevention and recycling are different dimensions of waste management behaviour. - Abstract: Understanding waste prevention behaviour (WPB) could enable local governments and decision makers to design more-effective policies for reducing the amount of waste that is generated. By merging well-known attitude-behaviour theories with elements from wider models from environmental psychology,more » an extensive cognitive framework that provides new and valuable insights is developed for understanding the involvement of individuals in waste prevention. The results confirm the usefulness of the theory of planned behaviour and of Schwartz's altruistic behaviour model as bases for modelling participation in waste prevention. A more elaborate integrated model of prevention was shown to be necessary for the complete analysis of attitudinal aspects associated with waste prevention. A postal survey of 158 respondents provided empirical support for eight of 12 hypotheses. The proposed structural equation indicates that personal norms and perceived behaviour control are the main predictors and that, unlike the case of recycling, subjective norms have a weak influence on WPB. It also suggests that, since social norms have not presented a direct influence, WPB is likely to be influenced by a concern for the environment and the community as well by perceptions of moral obligation and inconvenience. Results also proved that recycling and waste prevention represent different dimensions of waste management behaviour requiring particular approaches to increase individuals' engagement in future policies.« less

Pneumonia is the 2nd leading cause of years of life lost worldwide and is a common cause of adult admissions to hospital in sub-Saharan Africa. Risk factors for adult pneumonia are well characterised in developed countries, but are less well described in sub-Saharan Africa where HIV is a major contributing factor. Exposure to indoor and outdoor air pollution is high, and tobacco smoking prevalence is increasing in sub-Saharan Africa, yet the contribution of these factors to the burden of chronic respiratory diseases in sub-Saharan Africa remains poorly understood. Furthermore, the extent to which the presence of chronic respiratory diseases and exposure to air pollution contribute to the burden of pneumonia is not known. The Acute Infection of the Respiratory Tract Study (The AIR Study) is a case-control study to identify preventable risk factors for adult pneumonia in the city of Blantyre, Malawi. Cases will be adults admitted with pneumonia, recruited from Queen Elizabeth Central Hospital, the largest teaching hospital in Malawi. Controls will be adults without pneumonia, recruited from the community. The AIR Study will recruit subjects and analyse data within strata defined by positive and negative HIV infection status. All participants will undergo thorough assessment for a range of potential preventable risk factors, with an emphasis on exposure to air pollution and the presence of chronic respiratory diseases. This will include collection of questionnaire data, clinical samples (blood, urine, sputum and breath samples), lung function data and air pollution monitoring in their home. Multivariate analysis will be used to identify the important risk factors contributing to the pneumonia burden in this setting. Identification of preventable risk factors will justify research into the effectiveness of targeted interventions to address this burden in the future. The AIR Study is the first study of radiologically confirmed pneumonia in which air pollution exposure measurements have been undertaken in this setting, and will contribute important new information about exposure to air pollution in urban SSA. Through identification of preventable risk factors, the AIR Study aims to facilitate future research and implementation of targeted interventions to reduce the high burden of pneumonia in SSA.

Primary prevention of pediatric abusive head trauma: a cost audit and cost-utility analysis.

2012-01-01

To obtain comprehensive, reliable data on the direct cost of pediatric abusive head trauma in New Zealand, and to use this data to evaluate the possible cost-benefit of a national primary prevention program. A 5 year cohort of infants with abusive head trauma admitted to hospital in Auckland, New Zealand was reviewed. We determined the direct costs of hospital care (from hospital and Ministry of Health financial records), community rehabilitation (from the Accident Compensation Corporation), special education (from the Ministry of Education), investigation and child protection (from the Police and Child Protective Services), criminal trials (from the Police, prosecution and defence), punishment of offenders (from the Department of Corrections) and life-time care for moderate or severe disability (from the Accident Compensation Corporation). Analysis of the possible cost-utility of a national primary prevention program was undertaken, using the costs established in our cohort, recent New Zealand national data on the incidence of pediatric abusive head trauma, international data on quality of life after head trauma, and published international literature on prevention programs. There were 52 cases of abusive head trauma in the sample. Hospital costs totaled $NZ2,433,340, child protection $NZ1,560,123, police investigation $NZ1,842,237, criminal trials $NZ3,214,020, punishment of offenders $NZ4,411,852 and community rehabilitation $NZ2,895,848. Projected education costs for disabled survivors were $NZ2,452,148, and the cost of projected lifetime care was $NZ33,624,297. Total costs were $NZ52,433,864, averaging $NZ1,008,344 per child. Cost-utility analysis resulted in a strongly positive economic argument for primary prevention, with expected case scenarios showing lowered net costs with improved health outcomes. Pediatric abusive head trauma is very expensive, and on a conservative estimate the costs of acute hospitalization represent no more than 4% of lifetime direct costs. If shaken baby prevention programs are effective, there is likely to be a strong economic argument for their implementation. This study also provides robust data for future cost-benefit analysis in the field of abusive head trauma prevention. Copyright © 2012 Elsevier Ltd. All rights reserved.

Objectives To estimate the present value of current and future funding needed for HIV treatment and prevention in 9 sub-Saharan African (SSA) countries that account for 70% of HIV burden in Africa under different scenarios of intervention scale-up. To analyse the gaps between current expenditures and funding obligation, and discuss the policy implications of future financing needs. Design We used the Goals module from Spectrum, and applied the most up-to-date cost and coverage data to provide a range of estimates for future financing obligations. The four different scale-up scenarios vary by treatment initiation threshold and service coverage level. We compared the model projections to current domestic and international financial sources available in selected SSA countries. Results In the 9 SSA countries, the estimated resources required for HIV prevention and treatment in 2015–2050 range from US$98 billion to maintain current coverage levels for treatment and prevention with eligibility for treatment initiation at CD4 count of <500/mm3 to US$261 billion if treatment were to be extended to all HIV-positive individuals and prevention scaled up. With the addition of new funding obligations for HIV—which arise implicitly through commitment to achieve higher than current treatment coverage levels—overall financial obligations (sum of debt levels and the present value of the stock of future HIV funding obligations) would rise substantially. Conclusions Investing upfront in scale-up of HIV services to achieve high coverage levels will reduce HIV incidence, prevention and future treatment expenditures by realising long-term preventive effects of ART to reduce HIV transmission. Future obligations are too substantial for most SSA countries to be met from domestic sources alone. New sources of funding, in addition to domestic sources, include innovative financing. Debt sustainability for sustained HIV response is an urgent imperative for affected countries and donors. PMID:26948960

A mathematical model of the impact of present and future malaria vaccines.

PubMed

Wenger, Edward A; Eckhoff, Philip A

2013-04-15

With the encouraging advent of new malaria vaccine candidates, mathematical modelling of expected impacts of present and future vaccines as part of multi-intervention strategies is especially relevant. The impact of potential malaria vaccines is presented utilizing the EMOD model, a comprehensive model of the vector life cycle coupled to a detailed mechanistic representation of intra-host parasite and immune dynamics. Values of baseline transmission and vector feeding behaviour parameters are identified, for which local elimination is enabled by layering pre-erythrocytic vaccines of various efficacies on top of high and sustained insecticide-treated net coverage. The expected reduction in clinical cases is further explored in a scenario that targets children by adding a pre-erythrocytic vaccine to the EPI programme for newborns. At high transmission, there is a minimal reduction in clinical disease cases, as the time to infection is only slightly delayed. At lower transmission, there is an accelerating community-level protection that has subtle dependences on heterogeneities in vector behaviour, ecology, and intervention coverage. At very low transmission, the trend reverses as many children are vaccinated to prevent few cases. The maximum-impact setting is one in which the impact of increasing bed net coverage has saturated, vector feeding is primarily outdoors, and transmission is just above the threshold where small perturbations from a vaccine intervention result in large community benefits.

In 2009, the Japan Anti-Doping Agency (JADA) established the "Sports Pharmacist Accreditation Program" to prevent doping in sports. Since then, anti-doping activities in Japan have been attracting attention. In this study, we investigated research about the current status of doping from 2007 to 2014 in Japan to make anti-doping activities more concrete, and we also discussed future anti-doping activities by pharmacists. In Japan, bodybuilding was the sporting event with the highest number and rate of doping from 2007 to 2014. Many of the positive doping cases were detected for class S1 (anabolic agents), S5 (diuretics and masking agents), and S6 (stimulants). Within class S1, supplements were the main cause of positive doping. Within class S5, medicines prescribed by medical doctors were the main cause of positive doping. Within class S6, non-prescription medicines (e.g., OTC) were the main cause of positive doping. When we looked at the global statistics on doping, many of the positive doping cases were detected for class S1. On comparing the Japanese statistics with the global statistics, the rate of positive doping caused by class S1 was significantly lower, but that caused by classes S5 and S6 was significantly higher in Japan than in the world. In conclusion, pharmacists in Japan should pay attention to class S1, S5, and S6 prohibited substances and to the sport events of bodybuilding. Based on this study, sports pharmacists as well as common pharmacists should suggest new anti-doping activities to prevent doping in the future.

Conflicts between religious or spiritual beliefs and pediatric care: informed refusal, exemptions, and public funding.

PubMed

2013-11-01

Although respect for parents' decision-making authority is an important principle, pediatricians should report suspected cases of medical neglect, and the state should, at times, intervene to require medical treatment of children. Some parents' reasons for refusing medical treatment are based on their religious or spiritual beliefs. In cases in which treatment is likely to prevent death or serious disability or relieve severe pain, children's health and future autonomy should be protected. Because religious exemptions to child abuse and neglect laws do not equally protect all children and may harm some children by causing confusion about the duty to provide medical treatment, these exemptions should be repealed. Furthermore, public health care funds should not cover alternative unproven religious or spiritual healing practices. Such payments may inappropriately legitimize these practices as appropriate medical treatment.

The current mechanism for obtaining financial support for families with neurologically impaired infants is seriously flawed. It relies on payment awarded through the tort system based on a claim that medical negligence was responsible for the infant's condition. The system is extraordinarily inefficient and expensive, as well as being unfair to many families with affected children and to physicians who are unjustly accused of contributing to outcomes they could not have prevented. Furthermore, the exorbitant malpractice premiums necessary to support the system are threatening the future of obstetric practice in the United States. This article describes a two-pronged program designed to correct these inequities and to assess each case for the occurrence of medical negligence, which has been submitted to the New York State legislature as a proposed bill entitled the Neurologically Impaired Program for New York State (S7748).

Colorectal cancer (CRC) is the third most common cancer diagnosis and the second and third leading cause of cancer mortality in men and women, respectively. However, the majority of CRC cases are the result of sporadic tumorigenesis via the adenoma–carcinoma sequence. This process can take up to 20 years, suggesting an important window of opportunity exists for prevention such as switching toward healthier dietary patterns. The Mediterranean diet (MD) is a dietary pattern associated with various health benefits including protection against cardiovascular disease, diabetes, obesity, and various cancers. In this article, we review publications available in the PubMed database within the last 10 years that report on the impact of a MD eating pattern on prevention of CRC. To assist the reader with interpretation of the results and discussion, we first introduce indexes and scoring systems commonly used to experimentally determine adherence to a MD, followed by a brief introduction of the influence of the MD pattern on inflammatory bowel disease, which predisposes to CRC. Finally, we discuss key biological mechanisms through which specific bioactive food components commonly present in the MD are proposed to prevent or delay the development of CRC. We close with a discussion of future research frontiers in CRC prevention with particular reference to the role of epigenetic mechanisms and microbiome related to the MD eating pattern.

Public health plays an important role in ensuring access to interventions that can prevent disease, including the implementation of evidence-based genomic recommendations. We used the Centers for Disease Control and Prevention (CDC) Science Impact Framework to trace the impact of public health activities and partnerships on the implementation of the 2009 Evaluation of Genomic Applications in Practice and Prevention (EGAPP) Lynch Syndrome screening recommendation and the 2005 and 2013 United States Preventive Services Task Force (USPSTF) BRCA1 and BRCA2 testing recommendations.The EGAPP and USPSTF recommendations have each been cited by >300 peer-reviewed publications. CDC funds selected states to build capacity to integrate these recommendations into public health programs, through education, policy, surveillance, and partnerships. Most state cancer control plans include genomics-related goals, objectives, or strategies. Since the EGAPP recommendation, major public and private payers now provide coverage for Lynch Syndrome screening for all newly diagnosed colorectal cancers. National guidelines and initiatives, including Healthy People 2020, included similar recommendations and cited the EGAPP and USPSTF recommendations. However, disparities in implementation based on race, ethnicity, and rural residence remain challenges. Public health achievements in promoting the evidence-based use of genomics for the prevention of hereditary cancers can inform future applications of genomics in public health.

Background and Objectives: Addicts account for approximately 68.15% of AIDS cases in Iran and injection drug users are considered as a major factor in the spread of AIDS in Iran. The purpose of this study was to determine the effect of an educational intervention on the perceived self-efficacy, benefits, and barriers concerning AIDS preventive behaviors among drug addicts in Khorramabad, Iran. Methods: This is a quasi-experimental study carried out in 2013 on 88 addicts kept in rehabilitations center in Khorramabad. The data collection instruments included a questionnaire on self-efficacy, perceived benefits, perceived barriers, knowledge and preventive behaviors regarding HIV. Data were analyzed by paired t-test, independent t-test, Chi-square and analysis of covariance. Results: Paired t-test showed that the mean scores for perceived benefits and barriers, knowledge and preventive behaviors significantly increased in the intervention group after the intervention than before the intervention. But the increase in self-efficacy score was not statistically significant. Conclusions: The results of this study showed that training and education based on the health belief model led to an increase in knowledge, self-efficacy, perceived benefits, performance and reduction in perceived barriers in addicts. It is recommended that future studies should include strategies for enhancing self-efficacy and perceived benefits as well as strategies for reducing barriers to the adoption of preventive behaviors.

2013-01-01

In response to growing interest in economic analyses of prevention efforts, a diverse group of prevention researchers, economists, and policy analysts convened a scientific panel, on “Research Priorities in Economic Analysis of Prevention” at the 19th annual conference of the Society for Prevention Research. The panel articulated four priorities that, if followed in future research, would make economic analyses of prevention efforts easier to compare and more relevant to policymakers, and community stakeholders. These priorities are: (1) increased standardization of evaluation methods, (2) improved economic valuation of common prevention outcomes, (3) expanded efforts to maximize evaluation generalizability and impact, as well as (4) enhanced transparency and communicability of economic evaluations. In this paper we define three types of economic analyses in prevention, provide context and rationale for these four priorities as well as related sub-priorities, and discuss the challenges inherent in meeting them.

Control and prevention of canine rabies: the need for building laboratory-based surveillance capacity.

Dogs are the source of more than 99% of human rabies virus infections in endemic regions. Without postexposure prophylaxis, almost all cases are fatal, making rabies the most lethal infectious disease. Tens of thousands of deaths are reported annually, but the official figures are believed to be gross underestimates. Controlling canine rabies, especially in free-ranging dogs, is the first priority to reduce the burden of human disease. Because of their limited medical infrastructure, most endemic countries lack the laboratory facilities needed to diagnose human cases of viral encephalitis. Moreover, the veterinary sectors are often unable to undertake systematic surveillance and reporting of rabies in animals. Without an adequate and functioning risk assessment system that is primed for use, rabies will remain a 'neglected' and omnipresent disease, especially in poverty-stricken regions of the world. Fortunately, experience with the elimination of canine rabies from many industrialized countries has shown that these barriers are not insurmountable. Successful rabies prevention and control strategies that prove the absence of the disease depend on laboratory-based surveillance, rapid data reporting and an adequate system of risk assessment. Future control and prevention programmes should therefore coordinate the development of these key factors, creating synergies to eliminate rabies at its animal source. This article forms part of a symposium in Antiviral Research on the global elimination of canine rabies. Crown Copyright © 2013. Published by Elsevier B.V. All rights reserved.

2002-01-01

This article focuses on understanding epidemiological features of alveolar echinococcosis and discussing its prevention and control, especially from a viewpoint of the ecosystem and risk management. Publications on alveolar echinococcosis throughout the world were systematically reviewed with special reference to ecology, epidemiology and countermeasures. Alveolar echinococcosis, caused by accidental infection with larva of the parasite Echinococcus multilocularis is fatal to humans unless diagnosed at an early stage. No effective control measures have been identified so far because it is difficult to fully understand the ecology of the parasite and its intermediate and definitive hosts. It is also not easy to determine the precise infection route to humans mainly because of the long latent period. In Hokkaido, infection rates among red foxes have recently risen even in low endemic districts. Not only stray and domestic dogs but also some pigs in Hokkaido have been found to be infected. While the number of reported human cases is still small, around 10 cases per year, local residents seem to be threatened with the risk of infection. We predict that the incidence of alveolar echinococcosis among humans in Japan will increase in the near future if no effective preventive measures are conducted. In addition, Echinococcus multilocularis infection has the potential to affect the economy of Hokkaido because of its impact on the agricultural and tourist industries. Well-designed epidemiological surveys are therefore urgently required, in the context of ecosystem and risk management prior to large outbreaks. International collaboration is also desired.

Eating disorders (EDs), including anorexia nervosa (AN) and bulimia nervosa (BN), are prevalent disorders that carry substantial economic and social burden. The aim of the current study was to evaluate the modelled population cost-effectiveness of cognitive dissonance (CD), a school-based preventive intervention for EDs, in the Australian health care context. A population-based Markov model was developed to estimate the cost per disability adjusted life-year (DALY) averted by CD relative to no intervention. We modelled the cases of AN and BN that could be prevented over a 10-year time horizon in each study arm and the subsequent reduction in DALYs associated with this. The target population was 15-18 year old secondary school girls with high body-image concerns. This study only considered costs of the health sector providing services and not costs to individuals. Multivariate probabilistic and one-way sensitivity analyses were conducted to test model assumptions. Findings showed that the mean incremental cost-effectiveness ratio at base-case for the intervention was $103,980 per DALY averted with none of the uncertainty iterations falling below the threshold of AUD$50,000 per DALY averted. The evaluation was most sensitive to estimates of participant rates with higher rates associated with more favourable results. The intervention would become cost-effective (84% chance) if the effect of the intervention lasted up to 5 years. As modelled, school-based CD intervention is not a cost-effective preventive intervention for AN and BN. Given the burden of EDs, understanding how to improve participation rates is an important opportunity for future research. © 2017 Wiley Periodicals, Inc.

Prediabetes and Lifestyle Modification: Time to Prevent a Preventable Disease

PubMed Central

Tuso, Phillip

2014-01-01

More than 100 million Americans have prediabetes or diabetes. Prediabetes is a condition in which individuals have blood glucose levels higher than normal but not high enough to be classified as diabetes. People with prediabetes have an increased risk of Type 2 diabetes. An estimated 34% of adults have prediabetes. Prediabetes is now recognized as a reversible condition that increases an individual’s risk for development of diabetes. Lifestyle risk factors for prediabetes include overweight and physical inactivity. Increasing awareness and risk stratification of individuals with prediabetes may help physicians understand potential interventions that may help decrease the percentage of patients in their panels in whom diabetes develops. If untreated, 37% of the individuals with prediabetes may have diabetes in 4 years. Lifestyle intervention may decrease the percentage of prediabetic patients in whom diabetes develops to 20%. Long-term data also suggest that lifestyle intervention may decrease the risk of prediabetes progressing to diabetes for as long as 10 years. To prevent 1 case of diabetes during a 3-year period, 6.9 persons would have to participate in the lifestyle intervention program. In addition, recent data suggest that the difference in direct and indirect costs to care for a patient with prediabetes vs a patient with diabetes may be as much as $7000 per year. Investment in a diabetes prevention program now may have a substantial return on investment in the future and help prevent a preventable disease. PMID:25102521

Preventing the preventable through effective surveillance: the case of diphtheria in a rural district of Maharashtra, India

PubMed Central

2013-01-01

Background Epidemic diphtheria is still poorly understood and continues to challenge both developing and developed countries. In the backdrop of poor immunization coverage, non-existent adult boosters, weak case based surveillance and persistence of multiple foci, there is a heightened risk of re-emergence of the disease in epidemic forms in India. Investigating each outbreak to understand the epidemiology of the disease and its current status in the country is therefore necessary. Dhule a predominantly tribal and rural district in Northern Maharashtra has consistently recorded low vaccination coverages alongside sporaidic cases of diphtheria over the last years. Methods This study reports the findings of an onsite survey conducted to assess a recent outbreak of diphtheria in Dhule district and the response mounted to it. Secondary data regarding outbreak detection and response were obtained from the district surveillance office. Clinical data were extracted from hospital records of eleven lab confirmed cases including one death case. Frequency distributions were calculated for each identified clinical and non- clinical variable using Microsoft™ Excel® 2010. Results Our findings suggest a shift in the median age of disease to adolescents (10-15 years) without gender differences. Two cases (18%) reported disease despite immunization. Clinical symptoms included cough (82%), fever (73%), and throat congestion (64%). About 64% and 36% of the 11 confirmed cases presented with a well defined pseudomembrane and a tonsillar patch respectively. Drug resistance was observed in all three culture positive cases. One death occurred despite the administration of Anti-Diphtheric Serum in a partially immunized case (CFR 9%). Genotyping and toxigenicity of strain was not possible due to specimen contamination during transport as testing facilities were unavailable in the district. Conclusions The outbreak raises several concerns regarding the epidemiology of diphtheria in Dhule. The reason for shift in the median age despite consistently poor immunization coverage (below 50%) remains unclear. Concomitant efforts should now focus on improving and monitoring primary immunization and booster coverages across all age groups. Gradually introducing adult immunization at ten year intervals may become necessary to prevent future vulnerabilities. Laboratory networks for genotyping and toxigenicity testing are urgently mandated at district level given the endemicity of the disease in the surrounding region and its recent introduction in remote Dhule. Contingency funds with pre- agreements to obtain ADS and DT/Td vaccines at short notice and developing standard case management protocols at district level are necessary. Monitoring the disease, emerging strains and mutations, alongside drug resistance through robust and effective surveillance is a pragmatic way forward. PMID:23566309

Current problems facing the primary prevention of sexual assault are reviewed. Effective sexual assault prevention programs for both males and females have been slow to develop due to the fact that the etiologies of sexual assault have not been identified. Although dissemination of prevention programs has become increasingly popular in recent years, few programs have evaluated the extent to which the constructs identified in the interventions are effective at decreasing rates of sexual assault. This article discusses previous studies in sexual assault prevention programs, methodological and conceptual problems that currently exist in the field, pragmatic difficulties regarding program implementation and evaluation, and recommendations for future research with an emphasis on interventions with female participants.

As indicated by research on the long-term effects of adverse childhood experiences (ACEs), maltreatment has far-reaching consequences for affected children. Effective prevention measures have been elusive, partly due to difficulty in identifying vulnerable children before they are harmed. This study employs Risk Terrain Modeling (RTM), an analysis of the cumulative effect of environmental factors thought to be conducive for child maltreatment, to create a highly accurate prediction model for future substantiated child maltreatment cases in the City of Fort Worth, Texas. The model is superior to commonly used hotspot predictions and more beneficial in aiding prevention efforts in a number of ways: 1) it identifies the highest risk areas for future instances of child maltreatment with improved precision and accuracy; 2) it aids the prioritization of risk-mitigating efforts by informing about the relative importance of the most significant contributing risk factors; 3) since predictions are modeled as a function of easily obtainable data, practitioners do not have to undergo the difficult process of obtaining official child maltreatment data to apply it; 4) the inclusion of a multitude of environmental risk factors creates a more robust model with higher predictive validity; and, 5) the model does not rely on a retrospective examination of past instances of child maltreatment, but adapts predictions to changing environmental conditions. The present study introduces and examines the predictive power of this new tool to aid prevention efforts seeking to improve the safety, health, and wellbeing of vulnerable children.

[Domestic elder abuse and neglect--conclusions from the evaluation of a model project].

PubMed

Görgen, T; Nägele, B

2005-02-01

The main task of a federally funded model project in the German city of Hannover was to develop approaches for prevention and intervention in the field of domestic elder abuse. Over a three year period (1998-2001), different approaches--like a telephone helpline for senior citizens, and social workers operating as counsellors for elderly people and their relatives--were tested at a local level. The paper presents results from the evaluation of the project and draws conclusions for future prevention and intervention in the field. The authors argue that the explicit use of the conceptual framework of "violence"/"abuse" creates potentials for scandalizing the issue and is therefore supportive for media appearance, whereas it can impede the approach to the main target groups (elderly people and their relatives) and reduce accessibility of counselling services for potential clients. In the light of evaluation results the focus of the project ("domestic elder abuse" or "violence against elderly people in close relationships") was too narrow for a local project. Counselling services were used in a relatively small number of cases; analyses of cases show that incidents of domestic elder abuse are often embedded in complex problem constellations. Cases brought to the attention of the model project were multifaceted and not limited to incidents of neglect and abuse of elderly care recipients caused by caregiver overload. Cases of intimate violence in partnerships and of intergenerational violence without any of the participants being dependent on care show the need to develop a broader concept of domestic elder abuse. Integration of the concepts of domestic violence, violence against women, elder abuse/neglect and abuse/neglect in caregiving relationships is necessary on a conceptual level as well as on the level of interagency cooperation of institutions dealing with cases of "elder abuse".

Enteric disease episodes and the risk of acquiring a future sexually transmitted infection: a prediction model in Montreal residents.

2016-11-01

The sexual transmission of enteric diseases poses an important public health challenge. We aimed to build a prediction model capable of identifying individuals with a reported enteric disease who could be at risk of acquiring future sexually transmitted infections (STIs). Passive surveillance data on Montreal residents with at least 1 enteric disease report was used to construct the prediction model. Cases were defined as all subjects with at least 1 STI report following their initial enteric disease episode. A final logistic regression prediction model was chosen using forward stepwise selection. The prediction model with the greatest validity included age, sex, residential location, number of STI episodes experienced prior to the first enteric disease episode, type of enteric disease acquired, and an interaction term between age and male sex. This model had an area under the curve of 0.77 and had acceptable calibration. A coordinated public health response to the sexual transmission of enteric diseases requires that a distinction be made between cases of enteric diseases transmitted through sexual activity from those transmitted through contaminated food or water. A prediction model can aid public health officials in identifying individuals who may have a higher risk of sexually acquiring a reportable disease. Once identified, these individuals could receive specialized intervention to prevent future infection. The information produced from a prediction model capable of identifying higher risk individuals can be used to guide efforts in investigating and controlling reported cases of enteric diseases and STIs. © The Author 2016.

Informed Choice in Direct-to-Consumer Genetic Testing for Alzheimer and Other Diseases: Lessons from Two Cases

PubMed Central

Messner, Donna A.

2011-01-01

Health-related direct-to-consumer (DTC) genetic testing has been a controversial practice. Especially problematic is predictive testing for Alzheimer disease (AD), since the disease is incurable, prevention is inconclusive, and testing does not definitively predict an individual’s future disease status. In this paper, I examine two contrasting cases of subjects who learn through genetic testing that they have an elevated risk of developing AD later in life. In these cases, the subject’s emotional response to the result is related to how well prepared she was for the real-life personal implications of possible test results. Analysis leads to the conclusion that when groups of health-related genetic tests are offered as packages by DTC companies, informed consumer choice is rendered impossible. Moreover, I argue, this marketing approach contravenes U.S. Federal Trade Commission policies for non-deceptive commercial communications. I conclude by suggesting ways to improve the prospects for informed consumer choice in DTC testing. PMID:21603253

The escalator is very crucial to transport a person from one place to another. Nevertheless, there are many cases recorded the accidents in relation to escalator. These may occur due to lack of maintenance which leads to systems breakdown, poor safety practices, wear and tear, users’ negligence and others. Thus, proper maintenance systems need to be improvised to prevent and reduce escalator accident in future. This research was aimed to determine the escalator maintenance activities and safety practices in a commercial building. Three case studies were selected within Selangor area. Semi-structured interviews were conducted for collecting data from these three case studies. To achieve the aim of this research, the study was carried out on the maintenance activities, safety practices and cost related to escalator maintenance. As one of the important means of access in building, it is very crucial to increase effectiveness of escalator particularly in commercial building. It is expected that readers will get clear information on the maintenance activities and safety practices of escalator in commercial building.

Since the first outbreak of human infection with avian influenza A (H7N9) virus was identified in 2013, five seasonal outbreaks have occurred in China. The fifth outbreak started earlier than usual. A sudden increase in cases of human infection with avian influenza A (H7N9) virus has been reported in China since September 2016, and the number of cases reported in this season is exceeding that reported in previous seasons. This increase in the number of new cases of H7N9 infection has caused domestic and international concern. This paper summarizes the current prevalence of H7N9 in China and it also discusses measures that China has taken to control this outbreak. This paper also describes steps China must take in the future. This paper can serve as a reference for prevention and control of H7N9 outbreaks around the world.

Clinical Effects and Lethal and Forensic Aspects of Propofol*

Levy, Richard J.

2010-01-01

Propofol is a potent intravenous anesthetic agent that rapidly induces sedation and unconsciousness. The potential for propofol dependency, recreational use and abuse has only recently been recognized and several cases of accidental overdose and suicide have emerged. In addition, the first documented case of murder using propofol was reported a few months ago and a high profile case of suspected homicide with propofol is currently under investigation. A number of analytical methods have been employed to detect and quantify propofol concentrations in biological specimens. The reported propofol related deaths and post-mortem blood and tissue levels are reviewed. Importantly, limitations of propofol detection are discussed and future considerations are presented. Because propofol has the potential for diversion with lethal consequences, the forensic scientist must have a basic understanding of its clinical indications and uses, pharmacologic properties, and detection methods. In addition, medical institutions should develop systems to prevent and detect diversion of this potential drug of abuse. PMID:20950316

2017-01-01

Dens invaginatus is one of the most common anomalies of tooth structure. It is caused by the invagination of the crown surface during odontogenesis that enters the pulp chamber of the affected tooth. Depending on the complexity of invagination, the tooth might present with pulp necrosis, open apex and a complicated root canal system. This case report presents an Oehlers' type 2 dens-invaginatus in a mandibular premolar with chronic apical abscess. In most cases, dens invaginatus is removed during treatment. However, in this case report, based on cone-beam computed tomography (CBCT) evaluation, non-surgical treatment and maintenance of the invaginated segment was chosen in order to prevent compromising the tooth structure and its susceptibility to future root fracture. This is a new treatment approach and has not been performed in previous reports. Calcium-enriched mixture (CEM) cement was used as an apical plug followed by gutta-percha in warm vertical compaction for root canal obturation. The case was followed up for 36 months after treatment. This report highlights the importance of selecting the appropriate treatment approach based on CBCT evaluation.

2016-01-01

The National Violent Death Reporting System (NVDRS) is a United States Centers for Disease Control and Prevention (CDC) database of violent deaths from 2003 to the present. The NVDRS collects information from 32 states on several types of violent deaths, including suicides, homicides, homicides followed by suicides, and deaths resulting from child maltreatment or intimate partner violence, as well as legal intervention and accidental firearm deaths. Despite the availability of data from police narratives, medical examiner reports, and other sources, reliably finding the cases of murder-suicide in the NVDRS has proven problematic due to the lack of a unique code for murder-suicide incidents and outdated descriptions of case-finding procedures from previous researchers. By providing a description of the methods used to access to the NVDRS and coding procedures used to decipher these data, the authors seek to assist future researchers in correctly identifying cases of murder-suicide deaths while avoiding false positives. © 2015 American Academy of Forensic Sciences.

Fall Prediction and Prevention Systems: Recent Trends, Challenges, and Future Research Directions.

2017-11-01

Fall prediction is a multifaceted problem that involves complex interactions between physiological, behavioral, and environmental factors. Existing fall detection and prediction systems mainly focus on physiological factors such as gait, vision, and cognition, and do not address the multifactorial nature of falls. In addition, these systems lack efficient user interfaces and feedback for preventing future falls. Recent advances in internet of things (IoT) and mobile technologies offer ample opportunities for integrating contextual information about patient behavior and environment along with physiological health data for predicting falls. This article reviews the state-of-the-art in fall detection and prediction systems. It also describes the challenges, limitations, and future directions in the design and implementation of effective fall prediction and prevention systems.

Possible advantages of cervical pessaries include the easy, ‘one-off’ application, good side-effect profile, good patient tolerance and relatively low cost compared with current alternatives. Use of transvaginal sonography to assess cervical length in the second trimester allows much better selection of patients who may benefit from the use of a cervical pessary, but future clinical trials are needed to establish clearly the role of pessaries as a preterm birth prevention strategy worldwide.

Background: Tests of genotype may enable workers at unusual risk of future ill-health to be identified. Using them to select for employment, however, entails gains and losses to employers and employees. Ensuring a fair balance between the rights and obligations of each group requires a value judgement, but the advantages and disadvantages to interested parties must first be quantified in a meaningful way. Method and Results: The purposes of pre-employment screening are reviewed, and several simple measures relevant to the separate interests of employers and job applicants proposed—number screened to prevent a single adverse outcome; number excluded to prevent a case; expected incidence of the adverse outcome in those excluded; and preventable fraction. The derivation of these measures is illustrated, and the factors that influence them (the prevalence of the prognostic trait, the relative risk that it carries for an adverse outcome, and the overall incidence of disease) are related algebraically and graphically, to aid judgement on the utility of screening under different circumstances. Conclusions: In sensitive areas such as genetic testing the onus should be on the employer to justify plans for pre-placement screening. Several quantitative measures can be used to inform the ethical and economic debate about screening and to evaluate alternative strategies for prevention. PMID:15090667

Successful HIV prevention programming requires engaging communities in the planning process and responding to the social environmental factors that shape health and behaviour in a specific local context. We conducted two community-based situational analyses to inform a large, comprehensive HIV prevention programme in two rural districts of North West Province South Africa in 2012. The methodology includes: initial partnership building, goal setting and background research; 1 week of field work; in-field and subsequent data analysis; and community dissemination and programmatic incorporation of results. We describe the methodology and a case study of the approach in rural South Africa; assess if the methodology generated data with sufficient saturation, breadth and utility for programming purposes; and evaluate if this process successfully engaged the community. Between the two sites, 87 men and 105 women consented to in-depth interviews; 17 focus groups were conducted; and 13 health facilities and 7 NGOs were assessed. The methodology succeeded in quickly collecting high-quality data relevant to tailoring a comprehensive HIV programme and created a strong foundation for community engagement and integration with local health services. This methodology can be an accessible tool in guiding community engagement and tailoring future combination HIV prevention and care programmes.

Outbreaks of hand-foot-mouth disease (HFMD) have been reported for many times in Asia during the last decades. This emerging disease has drawn worldwide attention and vigilance. Nowadays, the prevention and control of HFMD has become an imperative issue in China. Early detection and response will be helpful before it happening, using modern information technology during the epidemic. In this paper, a hybrid model combining seasonal auto-regressive integrated moving average (ARIMA) model and nonlinear auto-regressive neural network (NARNN) is proposed to predict the expected incidence cases from December 2012 to May 2013, using the retrospective observations obtained from China Information System for Disease Control and Prevention from January 2008 to November 2012. The best-fitted hybrid model was combined with seasonal ARIMA [Formula: see text] and NARNN with 15 hidden units and 5 delays. The hybrid model makes the good forecasting performance and estimates the expected incidence cases from December 2012 to May 2013, which are respectively -965.03, -1879.58, 4138.26, 1858.17, 4061.86 and 6163.16 with an obviously increasing trend. The model proposed in this paper can predict the incidence trend of HFMD effectively, which could be helpful to policy makers. The usefulness of expected cases of HFMD perform not only in detecting outbreaks or providing probability statements, but also in providing decision makers with a probable trend of the variability of future observations that contains both historical and recent information.

Outbreak of Serratia marcescens Bloodstream Infections in Patients Receiving Parenteral Nutrition Prepared by a Compounding Pharmacy

2014-01-01

Background. Compounding pharmacies often prepare parenteral nutrition (PN) and must adhere to rigorous standards to avoid contamination of the sterile preparation. In March 2011, Serratia marcescens bloodstream infections (BSIs) were identified in 5 patients receiving PN from a single compounding pharmacy. An investigation was conducted to identify potential sources of contamination and prevent further infections. Methods. Cases were defined as S. marcescens BSIs in patients receiving PN from the pharmacy between January and March 2011. We reviewed case patients’ clinical records, evaluated pharmacy compounding practices, and obtained epidemiologically directed environmental cultures. Molecular relatedness of available Serratia isolates was determined by pulsed-field gel electrophoresis (PFGE). Results. Nineteen case patients were identified; 9 died. The attack rate for patients receiving PN in March was 35%. No case patients were younger than 18 years. In October 2010, the pharmacy began compounding and filter-sterilizing amino acid solution for adult PN using nonsterile amino acids due to a national manufacturer shortage. Review of this process identified breaches in mixing, filtration, and sterility testing practices. S. marcescens was identified from a pharmacy water faucet, mixing container, and opened amino acid powder. These isolates were indistinguishable from the outbreak strain by PFGE. Conclusions. Compounding of nonsterile amino acid components of PN was initiated due to a manufacturer shortage. Failure to follow recommended compounding standards contributed to an outbreak of S. marcescens BSIs. Improved adherence to sterile compounding standards, critical examination of standards for sterile compounding from nonsterile ingredients, and more rigorous oversight of compounding pharmacies is needed to prevent future outbreaks.

Objective Costs associated with HPV-related diseases such as cervical dysplasia, cervical cancer, and genital warts have not been evaluated in Sweden. These costs must be estimated in order to determine the potential savings if these diseases were eradicated and to assess the combined cost-effectiveness of HPV vaccination and cervical cancer screening. The present study aimed to estimate prevention, management, and treatment costs associated with cervical dysplasia, cervical cancer, and genital warts from a societal perspective in Sweden in 2009, 1 year before the quadrivalent HPV vaccination program was implemented. Methods and Materials Data from the Swedish cervical cancer screening program was used to calculate the costs associated with prevention (cytological cervical cancer screening), management (colposcopy and biopsy following inadequate/abnormal cytological results), and treatment of CIN. Swedish official statistics were used to estimate treatment costs associated with cervical cancer. Published epidemiological data were used to estimate the number of incident, recurrent, and persistent cases of genital warts; a clinical expert panel assessed management and treatment procedures. Estimated visits, procedures, and use of medications were used to calculate the annual cost associated with genital warts. Results From a societal perspective, total estimated costs associated with cervical cancer and genital warts in 2009 were €106.6 million, of which €81.4 million (76%) were direct medical costs. Costs associated with prevention, management, and treatment of CIN were €74 million; screening and management costs for women with normal and inadequate cytology alone accounted for 76% of this sum. The treatment costs associated with incident and prevalent cervical cancer and palliative care were €23 million. Estimated costs for incident, recurrent and persistent cases of genital warts were €9.8 million. Conclusion Prevention, management, and treatment costs associated with cervical dysplasia, cervical cancer, and genital warts are substantial. Defining these costs is important for future cost-effectiveness analyses of the quadrivalent HPV vaccination program in Sweden. PMID:26398189

Cancer prevention has been associated with decreased rates of cancer incidence and increased survival. Cancer prevention, however, can have a greater impact if barriers to implementing cancer prevention into practice are removed and opportunities are both fostered and seized. The purpose of this article is to identify barriers and opportunities to cancer prevention in clinical practice and provide recommendations for the future. A multidisciplinary team participated in “The Future Directions Cancer Prevention and Control: Workforce Implications for Training, Practice and Policy” workshop on October 17-18, 2009 at The University of Texas MD Anderson Cancer Center in Houston, TX. During the meeting, the team discussed barriers and opportunities for the implementation of cancer prevention into clinical practice. Further data were collected from peer-reviewed journals and published government and cancer agencies reports. Several issues were identified: 1) The funding allocated to basic cancer prevention research and application is not optimal and less than that for cancer treatment; 2) Participation in cancer prevention behaviors and screening practices are lower than desired, especially among the uninsured; 3) A shortage in healthcare professionals is a major challenge in meeting the future needs of cancer prevention; 4) Demands on medical schools to balance increased enrollment, incorporate cancer prevention in an already crowded curriculum, and develop faculty are daunting; and 5) Healthcare reforms in 2010 provide both opportunities and additional challenges for cancer prevention. Based on the current state of cancer prevention, we formed six recommendations: 1) Additional funding for cancer prevention research with a focus on implementation into practice; 2) Improved tracking of cancer prevention research funding and the outcomes associated with it; 3) Continued monitoring of cancer prevention services participation with emphasis on closing the gap in health disparities; 4) Financial and technical assistance to healthcare professional schools for incorporating cancer prevention into curricula; 5) Assessment of the current state of technology in cancer prevention care; and 6) The use of effective multidisciplinary teams in cancer prevention care. Improved delivery of cancer prevention services can have a tremendous impact on cancer incidence and survival rates. PMID:22367592

The U.K. government is making progress in its campaign to improve the safety of personnel working offshore. The government's Health and Safety Executive (HSE) plans to assess and pass judgment on at lease one safety plan, called a safety case, from each U.K. North Sea operator as soon as possible. HSE has agreed with the industry on a list of 61 priority safety cases, known as exemplars. Feedback from exemplar assessment will help operators review safety management and assist in preparation or revision of future safety cases. It also will give HSE practice in assessing a range of case types.more » The requirement for a safety program is part of new U.K. offshore legislation designed to prevent another accident similar to the Piper Alpha platform fire and explosion of 1988. After the transition period it will be against the law to operate an oil and gas installation in British waters without an accepted safety case. Besides existing installations, safety cases are also required for new installations reaching design stage by May 31, 1993, the date safety case regulations went into force. The paper describes the Cullen report, companies' experiences with the new law, and the safety assessment progress so far.« less

Early orthodontic interventions are often initiated in the developing dentition to promote favourable developmental changes. Interceptive orthodontic can eliminate or reduce the severity of a developing malocclusion, the complexity of orthodontic treatment, overall treatment time and cost. The safest way to prevent future malocclusions from tooth loss is to place a space maintainer that is effective and durable. An appropriate use of space maintainer is advocated to hold the space until the eruption of permanent teeth. This case report describes the various changing trends in use of space maintainers: conventional band and loop, prefabricated band with custom made loop and glass fibre reinforced composite resins as space maintainers.

Sonnenfeld, G.

1984-01-01

Several reports on immunologically related interferon research, both in the areas of basic science and clinical research, are briefly reviewed, and it is noted that in many cases the results obtained are contradictory. It is argued, however, that the contradictory results are not surprising since interferon is a biological response modifier and has been known to produce opposite results even when the same interferon prepartion is used. It is emphasized that dosage, timing, route, and other experimental conditions are essential factors in planning immunological studies with interferon. Careful planning of future experiments with interferon should be required to prevent the possible generation of effects that are opposite to those expected.

A 28-year-old man presented emergently to the operating room following a gun-shot injury to his right groin. Our hospital's Massive Transfusion Protocol was initiated as the patient entered the operating room actively hemorrhaging and severely hypotensive. During the aggressive resuscitation efforts, the patient was inadvertently transfused 2 units of packed red blood cells intended for another patient due to a series of errors. Fortunately, the incorrect product was compatible, and the patient recovered from his near-fatal injuries. Root cause analysis was used to review the transfusion error and develop an action plan to help prevent future occurrences.

[AIDS in the world: revolution, paradigm and solidarity].

Mann, J

AIDS in a single decade has affected life and assumptions on the societal and individual level more than any other illness or epidemic in history. The most important aspect of the HIV pandemic is that it is still in an early stage of development. The pandemic will continue to be volatile and dynamic; its greatest impact has not yet been felt. There is still great potential to influence its future course. HIV infection is spreading rapidly in some already affected populations in Africa, Latin America, and the Caribbean, and is penetrating deeply into new areas such as Eastern Europe, the Middle East, and Southeast Asia. Thailand and India are symbols of its rapid spread. The more than 100 million new cases of sexually transmitted diseases diagnosed in the world each year demonstrate the potential for sexual transmission of HIV. On the global level, the foundations have been laid for preventing the spread of HIV infection. But in many countries information is still inadequate or incorrect, needed social and health services are nonexistent, and punitive and discriminatory attitudes persist toward the infected. The gap between rich and poor within and between countries is widening. 2/3 of AIDS cases and 3/4 of seropositive individuals are in developing countries. The cost of drugs and treatment implies that "early intervention" is a meaningless concept for developing countries. The developed world contributes $200 million or less to combat AIDS in developing countries. Some of the revolutionary ideas prompted by the advent of AIDS included the immediate attention given to behavior as a preventive measure, the eradication of complacency about the condition of health and social services, the insistence of AIDS patients and the HIV infected on being included in the total process of prevention, treatment, and research, and the unexpected flowering of a dialogue on dignity, human rights, and social justice. AIDS is now leading to a new vision of health promotion in which individual and collective behavior is recognized as the greatest challenge for future health. Solidarity is a central aspect of the emerging perspective on health prompted by AIDS. The disease has revealed the inherent limitations of 2 alternatives to solidarity: coercion and discrimination.

Cervical artificial disc extrusion after a paragliding accident

2017-01-01

Background: Cervical total disc replacement (TDR) is an established alternative to anterior cervical discectomy and fusion (ACDF) with excellent long-term outcomes and low failure rates. Cases of implant failure and migration are scarce and primarily limited to several years postoperatively. The authors report a case of anterior extrusion of a C4-C5 ProDisc-C (DePuy Synthes, West Chester, PA, USA) cervical artificial disc (CAD) 14 months after placement due to minor trauma. Case Description: A 33-year-old female who had undergone C4-C5 CAD implantation presented with neck pain and spasm after experiencing a paragliding accident. A 4 mm anterior protrusion of the CAD was seen on x-ray. She underwent removal of the CAD followed by anterior fusion. Other cases of CAD extrusion in the literature are discussed and the device's durability and testing are considered. Conclusion: Overall, CAD extrusion is a rare event. This case is likely the result of insufficient osseous integration. Patients undergoing cervical TDR should avoid high-risk activities to prevent trauma that could compromise the disc's placement, and future design/research should focus on how to enhance osseous integration at the interface while minimizing excessive heterotopic ossification.

Objective: The extent to which childrens's welfare is compromised when they do not attend compulsory prevention medical check-ups is yet to be determined. Together with the Hessen Prevention Center for Children (Hessisches Kindervorsorgezentrum), the Child Protection Services in the Main-Taunus district have conducted a study to investigate failure to attend child preventive examinations as a possible indication of risk to the welfare of such children. Method: 605 notifications of child preventive examinations that were not carried out, sent in 2012 to the Child Protection Services by the Hessen Prevention Center for Children, were analyzed retrospectively. Each case was recorded using a standardized questionnaire and, cases that were passed on to General Social Services within Child Protection Services were investigated with an additional interview with the employee responsible. Results: In 60 (10%) cases there was no certificate to show that the check-up had been conducted, while in 165 (27%) cases the check-up was conducted late, i. e. only after being contacted by the Child Protection Services. In 9 of the 605 cases (1.5%), the families involved were already known to Child Protection Services due to previous proceedings against them under endangering children's welfare act (known as § 8a cases). No new case of a risk to children's welfare was detected. In 58 cases, families gave reasons for the missed or late check-up. Reasons included being abroad and moving house (20 cases), forgetting (14 cases) and illness (11 cases), as well as lack of knowledge of the law (6 cases), lack of health insurance (4 cases), lack of language skills (2 cases) and objection to the law in principle (1 case). It was notable that, in 57% of the cases notified, documentary evidence could be provided by the end of the case work that the check-up had taken place within the recommended period (including additional discretionary period). The majority of these notifications of failure to attend can be prevented by an upstream clearing procedure. © Georg Thieme Verlag KG Stuttgart · New York.

African-American young men who have sex with men and transgender persons are at elevated risk for HIV infection. House and Ball communities, networks of mostly African-American gay, bisexual, and transgender individuals who compete in modeling and dance, represent a prime venue for HIV prevention with these difficult-to-reach populations; however, little research exists on effective approaches to HIV prevention within these communities. Using a mixed-methods approach, the present study sought to document participation in HIV prevention activities of a sample from the Los Angeles House and Ball communities (n = 263) in order to inform future service development. While 80% of participants were tested for HIV within the past 6 months, only 26% report HIV prevention program attendance. House leaders recommend a holistic approach to HIV prevention, one that incorporates attention to social problems beyond HIV, including poverty, housing difficulties, and lack of job training.

The objective of this review is to provide a comprehensive overview of the different types of economic evaluations that can be utilized by Infection Prevention and Control practitioners with a particular focus on the use of the quality adjusted life year, and its associated challenges. We also highlight existing economic evaluations published within Infection Prevention and Control, research gaps and future directions. Narrative Review. To date the majority of economic evaluations within Infection Prevention and Control are considered partial economic evaluations. Acknowledging the challenges, which include variable utilities within infection prevention and control, a lack of randomized controlled trials, and difficulty in modelling infectious diseases in general, future economic evaluation studies should strive to be consistent with published guidelines for economic evaluations. This includes the use of quality adjusted life years. Further research is required to estimate utility scores of relevance within Infection Prevention and Control.

2017-01-01

Fall prediction is a multifaceted problem that involves complex interactions between physiological, behavioral, and environmental factors. Existing fall detection and prediction systems mainly focus on physiological factors such as gait, vision, and cognition, and do not address the multifactorial nature of falls. In addition, these systems lack efficient user interfaces and feedback for preventing future falls. Recent advances in internet of things (IoT) and mobile technologies offer ample opportunities for integrating contextual information about patient behavior and environment along with physiological health data for predicting falls. This article reviews the state-of-the-art in fall detection and prediction systems. It also describes the challenges, limitations, and future directions in the design and implementation of effective fall prediction and prevention systems. PMID:29104256

System engineering analysis of derelict collision prevention options

2013-08-01

Sensitivities to the future growth of orbital debris and the resulting hazard to operational satellites due to collisional breakups of large derelict objects are being studied extensively. However, little work has been done to quantify the technical and operational tradeoffs between options for minimizing future derelict fragmentations that act as the primary source for future debris hazard growth. The two general categories of debris mitigation examined for prevention of collisions involving large derelict objects (rocket bodies and payloads) are active debris removal (ADR) and just-in-time collision avoidance (JCA). Timing, cost, and effectiveness are compared for ADR and JCA solutions highlighting the required enhancements in uncooperative element set accuracy, rapid ballistic launch, despin/grappling systems, removal technologies, and remote impulsive devices. The primary metrics are (1) the number of derelict objects moved/removed per the number of catastrophic collisions prevented and (2) cost per collision event prevented. A response strategy that contains five different activities, including selective JCA and ADR, is proposed as the best approach going forward.

Prevention of Rheumatic Diseases: Strategies, Caveats and Future Directions

PubMed Central

Finckh, Axel

2014-01-01

Rheumatic diseases affect a significant portion of the population and lead to increased health care costs, disability and even premature mortality; as such, effective preventive measures for these diseases could lead to substantial improvements in public health. Importantly, established and emerging data from natural history studies show that for most rheumatic diseases there is a period of ‘preclinical’ disease development during which abnormal biomarkers or other processes can be detected. These changes are useful to understand mechanisms of disease pathogenesis; in addition, they may be applied to estimate a personal risk of future disease, while individuals are still relatively asymptomatic. Based on this, a hope is to implement effective screening and preventive approaches for some rheumatic diseases, perhaps in the near future. However, a key part of such approaches is a deep understanding of the mechanisms of disease development as well as evidence-based and effective screening and preventive interventions that incorporate disease biology as well as ethical and public health concerns.

To document the investigation and control of an outbreak of gastroenteritis in City G, South China, and provide a reference for preventing future outbreaks. An ambispective cohort study was designed. Attack rate (AR) and relative risks (RR) were calculated to identify the causes of gastroenteritis. Investigations using questionnaires included personal interviews with patients and doctors, reviews of medical records, laboratory examinations of fecal specimens and continuous hygiene monitoring of water samples from the waterworks. Overall, 427/71534 (AR=5.97%) cases were identified between October 31 and November 12 2010. Geographic distribution was highly localized, with 80% of cases occurring in the areas supplied by waterworks-A. Consumption of water provided solely by waterworks-A was found to be associated with illness (RR=8.20, 95 CI%:6.12-10.99) compared with that from waterworks-B. Microbiological analyses confirmed the presence of Norovirus in six of eight fecal samples from symptomatic patients, two water samples from waterworks-A and two sewage samples. After taking effective measures, the hygienic indices of waterworks-A met health criteria again on November 9 and no cases were reported 3 days later. The outbreak reported here was caused by drinking tap water contaminated with sewage at the source. Early identification of possible contamination sources and awareness of changes that might negatively impact water quality are important preventive measures to protect public health.

Schonhaut, Luisa; Pérez, Marcela; Muñoz, Sergio

2015-01-01

There is evidence that children born moderate-to-late preterm (MLP) have a higher risk of hospitalisation, neonatal morbidity, and developmental delay (DD). To determine the association between DD, gestational age, and neonatal morbidity in MLP children. A case control study design nested in a cohort of MLP children born between 2006 and 2009 at a private hospital located in the Metropolitan area of Santiago. The children were assessed with the Bayley-III Scales of Infant Development at 8 or 18 months corrected age, or at 30 months of chronological age. Neonatal records were retrospectively reviewed. A multivariate analysis was performed to determine the effect of neonatal morbidity on development. A total of 130 MLP children, 25 cases and 105 controls, were studied. Most of them (83.8%) were hospitalised during the neonatal period. Significant differences between cases and controls regarding maternal age and symptomatic hypoglycaemia were observed (crude OR 3.5, adjusted OR 8.18). It was concluded that the variables that negatively affect the rate of development are male gender, being a twin, and gestational age. Symptomatic hypoglycaemia is the main risk factor for DD, while being a twin, male gender, and gestational age influenced the total development rate obtained. It is essential to develop strategies for prevention, screening, and early management of this metabolic disorder to prevent future DD. Copyright © 2015 Sociedad Chilena de Pediatría.

Schools can address critical sexual and reproductive health (SRH) issues among youth. However, little is known about SRH education being implemented in charter schools. Thus, our purpose was to explore implementation of SRH education in charter schools. Using purposive sampling, semistructured telephone interviews were conducted with 20 charter school principals in San Diego County, California. Questions were guided by the Kaiser Family Foundation National Survey of Public Secondary School Principals. Analyses followed a case-oriented approach, examining aspects within each case (ie, a principal), and then a comparative analysis of a small number of cases (ie, all principals). Overall, 17 principals acknowledged offering sexuality education in the previous 2 years. Over half of these schools had provided content on: sexually transmitted diseases/human immunodeficiency virus/acquired immune deficiency syndrome (STDs/HIV/AIDS), reproduction/pregnancy/birth, pregnancy prevention methods, delaying sex, and managing sexual pressure. Condom use, sexual assault, sexual orientation, talking with partners about STD/pregnancy prevention, talking with parents about relationships/sex, and using/where to get contraception were less commonly taught. Abortion was not addressed. When asked the grade they would assign to their schools' sexuality/HIV instruction, principals assigned 1 A, 7 Bs, 7 Cs, and 1 D. Consistency between our findings and what has been reported elsewhere varies. As charter schools often have greater curricular flexibility than traditional schools, this study provides unique preliminary data to inform future innovative, or strengthen existing, SRH programming. © 2017, American School Health Association.

Objectives In Ibaraki Prefecture, all (nursery) schools have joined the (Nursery) School Absenteeism Surveillance System (hereafter denoted as (N)SASSy), which is operated by the Japan School Health Association to monitor the prevalence of infectious diseases, the early detection and response for outbreaks, and prevention of large outbreaks. Prefectural government officers also utilize it as a control measure for infectious diseases. In particular, when cases of measles or rubella are registered, (N)SASSy sends e-mails automatically to prefectural government officers to activate control measures. This paper summarizes administrative responses by prefectural government officers for measles or rubella cases using (N)SASSy and discusses the future challenges.Methods We summarized registration, detection, and first response data for measles or rubella cases in (N)SASSy and compared the number of detected and reported cases enforced by the Infectious Diseases Control Law from January 1, 2013 to December 31, 2014.Results The public health center questioned hospitals/clinics and (nursery) schools about all registered measles or rubella cases in (N)SASSy on the same day to check the entered information. In the past 2 years, there were 5 measles and 56 rubella cases in 2013 and 1 measles and 19 rubella cases in 2014 registered with (N)SASSy. All cases were checked and investigated by the public health center. Of all cases detected by (N)SASSy, 7 rubella cases in 2013 and 1 rubella case in 2014 were reported based on the law. No measles cases were reported in the 2 years. The results of investigations and laboratory tests were given as feedback to the (nursery) schools. If the case did not case definition determined by the law, we changed the status in (N)SASSy to suspected or discarded cases.Conclusion Since (N)SASSy assists prefectural government officers with earlier detection of and response for infectious diseases, it definitely contributes to infection control. Immediate feedback of the laboratory test results to the (nursery) schools was also useful to confirm cases of measles or rubella. As data entry in (nursery) schools is needed for stable operation and utilization of (N)SASSy, it is important that workshops for (N)SASSy are held for (nursery) school teachers every year to maintain accuracy. Our future challenges include the coordination among (nursery) schools, hospitals/clinics, and prefectural government and their applications for infection control.

In 2001, Maryland's court of appeals was asked to decide whether researchers at Johns Hopkins University had engaged in unethical research on children. During the 1990s, Johns Hopkins's Kennedy Krieger Institute had studied 108 African American children, aged 6 months to 6 years, to find an inexpensive and "practical" means to ameliorate lead poisoning. We have outlined the arguments in the case and the conundrum faced by public health researchers as they confront new threats to our health from environmental and industrial insults. We examined the case in light of contemporary public health ideology, which prioritizes harm reduction over the historical goals of prevention. As new synthetic toxins-such as bisphenyl A, polychlorinated biphenyls, other chlorinated hydrocarbons, tobacco, vinyl, and asbestos-are discovered to be biologically disruptive and disease producing at low levels, lead provides a window into the troubling dilemmas public health will have to confront in the future.

In this article, we review the indications and latest management of high-risk penetrating keratoplasty. Despite the immune-privilege status of the cornea, immune-mediated graft rejection still remains the leading cause of corneal graft failure. This is particularly a problem in the high-risk graft recipients, namely patients with previous graft failure due to rejection and those with inflamed and vascularized corneal beds. A number of strategies including both local and systemic immunosuppression are currently used to increase the success rate of high-risk corneal grafts. Moreover, in cases of limbal stem cell deficiency, limbal stem cells transplantation is employed. Corticosteroids are still the top medication for prevention and treatment in cases of corneal graft rejection. Single and combined administration of immunosuppressive agents e.g. tacrolimus, cyclosporine and mycophenolate are promising adjunctive therapies for prolonging graft survival. In the future, cellular and molecular therapies should allow us to achieve immunologic tolerance even in high-risk grafts.

Corona viruses cause common cold, and infections caused by corona viruses are generally self-resolving. During the last 4 years, corona viruses have become the most important viruses worldwide because of the occurrence of several recent deaths caused by corona viruses in Saudi Arabia. Spread of the infection occurred worldwide; however, most cases of mortality have occurred in the Middle East. Owing to the predominance of outbreaks in the Middle Eastern countries, the virus was renamed a Middle East respiratory syndrome corona virus (MERS-CoV) by the Corona virus Study Group. The Center for Diseases Control and Prevention and World Health Organization maintain a website that is updated frequently with new cases of MERS-CoV infection. In this review, we describe the history and epidemiology of this novel virus. Studies of the genetics and molecular mechanisms of this virus are expected to facilitate the development of vaccines in the future.

Intrinsic vulnerability, hazard and risk mapping for karst aquifers: A case study

Mimi, Ziad A.; Assi, Amjad

2009-01-01

SummaryGroundwater from karst aquifers is among the most important resources of drinking water supply of the worldwide population. The European COST action 620 proposed a comprehensive approach to karst groundwater protection, comprising methods of intrinsic and specific vulnerability mapping, hazard and risk mapping. This paper presents the first application of all components of this European approach to the groundwater underlying the Ramallah district, a karst hydrogeology system in Palestine. The vulnerability maps which were developed can assist in the implementation of groundwater management strategies to prevent degradation of groundwater quality. Large areas in the case study area can be classified as low or very low risk area corresponding to the pollution sources due to the absence of hazards and also due to low vulnerabilities. These areas could consequently be interesting for future development as they are preferable in view of ground water protection.

Traumatic workplace-related injuries (WRIs) carry a substantial negative impact on the public health worldwide. We aimed to study the incidence and outcomes of WRIs in Qatar. We conducted occupational injury surveillance for all WRI patients between 2010 and 2012. A total of 5152 patients were admitted to the level 1 trauma unit in Qatar, of which 1496 (29%) sustained WRI with a mean age of 34.3 ± 10.3. Fall from height (FFH) (51%) followed by being struck by heavy objects (FHO) (18%) and motor vehicle crashes (MVC) (17%) was the commonest mechanism of injury (MOI). WRI patients were mainly laborers involved in industrial work (43%), transportation (18%), installation/repair (12%), carpentry (9%), and housekeeping (3%). Use of protective device was not observed in 64% of cases. The mean ISS was 11.7 ± 8.9, median ICU stay was 3 days (1–64), and total hospital stay was 6 days (1–192). The overall case fatality was 3.7%. Although the incidence of WRI in Qatar is quite substantial, its mortality rate is relatively low in comparison to other countries of similar socioeconomic status. Prolonged hospital stay and treatment exert a significant socioeconomic burden on the nation's and families' resources. Focused and efficient injury prevention strategies are mandatory to prevent future WRI. PMID:24734049

Should child obesity be an issue for child protective services? A call for more research on this critical public health issue.

Given the lasting effects on adolescent and adult health, childhood obesity is a major public health issue. The relatively slow progress toward the prevention and treatment of childhood obesity, however, has prompted leaders in both academic and practice sectors to advocate for what may be considered a radical intervention approach, to conceptualize extreme child obesity as an issue of child maltreatment. Advocates of this approach suggest that this conceptualization affords a new angle for intervention-the involvement of child protective services (CPS) in mandating family-focused lifestyle changes aimed at reducing child overweight and, in the most extreme cases, the removal of the obese child from the home. However, surprisingly little research has been conducted to inform policies or practices consistent with this recommendation, which is already being implemented in some states. This article aims to provide an overview of the challenges to the prevention and treatment of childhood obesity that have motivated the call for CPS involvement in extreme cases and to review the existing research related to this approach. Given that relatively little data are currently available to support or refute the merits of CPS involvement, recommendations for future research that would better inform public policy and decision making regarding this and other intervention strategies are also highlighted.

This study investigated the diarrhoea seasonality and its potential drivers as well as potential opportunities for future diarrhoea control and prevention in China. Data on weekly infectious diarrhoea cases in 31 provinces of China from 2005 to 2012, and data on demographic and geographic characteristics, as well as climatic factors, were complied. A cosinor function combined with a Poisson regression was used to calculate the three seasonal parameters of diarrhoea in different provinces. Regression tree analysis was used to identify the predictors of diarrhoea seasonality. Diarrhoea cases in China showed a bimodal distribution. Diarrhoea in children <5 years was more likely to peak in fall-winter seasons, while diarrhoea in persons > = 5 years peaked in summer. Latitude was significantly associated with spatial pattern of diarrhoea seasonality, with peak and trough times occurring earlier at high latitudes (northern areas), and later at low latitudes (southern areas). The annual amplitudes of diarrhoea in persons > = 5 years increased with latitude (r = 0.62, P<0.001). Latitude 27.8° N and 38.65° N were the latitudinal thresholds for diarrhoea seasonality in China. Regional-specific diarrhoea control and prevention strategies may be optimal for China. More attention should be paid to diarrhoea in children <5 years during fall-winter seasons.

Can treatment-based HIV prevention curb the epidemic among gay and other men who have sex with men? A narrative synthesis of increasing evidence for moderating and countervailing effects.

PubMed

de Wit, John B F; Adam, Philippe C G

2014-07-01

As HIV epidemics among gay and other men who have sex with men (GMSM) persist worldwide, the importance of novel prevention approaches is recognised. Evidence that antiretroviral therapy (ART) can decrease the likelihood of infection is informing emerging HIV prevention approaches, encompassing early initiation of treatment as prevention by people living with HIV and use of antiretroviral drugs as pre-exposure prophylaxis for people presumed to be uninfected. Despite widespread excitement, robust evidence of the beneficial effects of ART-based HIV prevention for GMSM remains limited. Also, theoretical models project widely varying effects of ART-based prevention on the future course of HIV epidemics among GMSM, drawing attention to the possible moderating role of differences in the achievements of local HIV responses and the critical importance of sustained protective sexual practices into the future. Ecological analyses and simulations of ongoing epidemics in major gay communities illustrate that the preventive effects of ART in many settings are being offset by increased sexual risk-taking, as reflected in stable or increasing HIV infection rates. Also, the effects of scaling up HIV testing and treatment among GMSM in settings that are often considered prime examples of the success of ART-based prevention may be levelling as 'scope for improvement' diminishes. ART-based approaches further extend the HIV prevention toolkit and substantially increase people's options to protect themselves and others. The future impact of ART-based prevention on HIV epidemics among GMSM ultimately depends on whether heralded responses offset, attenuate or compound the ongoing social and behavioural changes that drive increased sexual risk.

Review article: Medical decision models of Helicobacter pylori therapy to prevent gastric cancer.

PubMed

Sonnenberg, A; Inadomi, J M

1998-02-01

The aim of the present article is to study the utility of Helicobacter pylori eradication programmes in decreasing the incidence of gastric cancer. Three types of decision models are employed to pursue this aim, i.e. decision tree, present value, and declining exponential approximation of life expectancy (DEALE). 1) A decision tree allows one to model the interaction of multiple variables in great detail and to calculate the marginal cost, as well as the marginal cost-benefit ratio, of a preventive strategy. The cost of gastric cancer, the efficacy of H. pylori therapy in preventing cancer, and the cumulative probability of developing gastric cancer exert the largest influence on the marginal cost of cancer prevention. The high cost of future gastric cancer and a high efficacy of therapy make screening for H. pylori and its eradication the preferred strategy. 2) The present value is an economic method to adjust future costs or benefits to their current value using a discount rate and the length of time between now and a given time point in the future. It accounts for the depreciation of money and all material values over time. During childhood, the present value of future gastric cancer is very low. Vaccination of children to prevent gastric cancer would need to be very inexpensive to be practicable. Cancer prevention becomes a feasible option, only if the time period between the preventive measures and the occurrence of gastric cancer can be made relatively short. 3) The DEALE provides a means to calculate the increase in life expectancy that would occur, if death from a particular disease became preventable. Life expectancy of the general population is hardly affected by gastric cancer. For life expectancy to increase appreciably by vaccination or antibiotic therapy directed against H. pylori infection, these interventions would need to be focused towards a sub-population with an a priori high risk for gastric cancer.

Economic analysis of Clostridium difficile infection (CDI) should consider the incentives facing institutional decision-makers. To avoid overstating the financial benefits of infection prevention, fixed and variable costs should be distinguished. To quantify CDI fixed and variable costs in a tertiary referral hospital during August 2015. A micro-costing analysis estimated CDI costs per patient, including the additional costs of a CDI outbreak. Resource use was quantified after review of patient charts, pharmacy data, administrative resource input, and records of salary and cleaning/decontamination expenditure. The incremental cost of CDI was €75,680 (mean: €5,820 per patient) with key cost drivers being cleaning, pharmaceuticals, and length of stay (LOS). Additional LOS ranged from 1.75 to 22.55 days. For seven patients involved in a CDI outbreak, excluding the value of the 58 lost bed-days (€34,585); costs were 30% higher (€7,589 per patient). Therefore, total spending on CDI was €88,062 (mean: €6,773 across all patients). Potential savings from variable costs were €1,026 (17%) or €1,768 (26%) if outbreak costs were included. Investment in an antimicrobial pharmacist would require 47 CDI cases to be prevented annually. Prevention of 5%, 10% and 20% CDI would reduce attributable costs by €4,403, €8,806 and €17,612. Increasing the incremental LOS attributable to CDI to seven days per patient would have increased costs to €7,478 or €8,431 (if outbreak costs were included). As much CDI costs are fixed, potential savings from infection prevention are limited. Future analysis must consider more effectively this distinction and its impact on institutional decision-making.

Suicide is an emerging, yet preventable global health issue associated with significant mortality. Identification of underlying risk factors and antecedents may inform preventive strategies and interventions. This study serves to provide an updated meta-analysis examining the extent of association of early life sexual abuse with suicide attempts. Using the keywords [early abuse OR childhood abuse OR sexual OR rape OR molest* OR violence OR trauma OR PTSD] AND [suicid* OR premature OR unnatural OR deceased OR died OR mortality], a preliminary search on the PubMed, Ovid, PsychINFO, Web of Science and Google Scholar databases yielded 12,874 papers published in English between 1-Jan-1988 and 1-June-2017. Of these, only 47 studies were included in the final meta-analysis. The 47 studies (25 cross-sectional, 14 cohort, 6 case-control and 2 twin studies) contained a total of 151,476 subjects. Random-effects meta-analysis found early life sexual abuse to be a significant risk factor for suicide attempts, compared to baseline population (pooled OR 1.89, 95% CI: 1.66 to 2.12, p < 0.001). Subgroup analyses of cross-sectional and longitudinal studies showed similar findings of increased risk as they yielded ORs of 1.98 (95% CI: 1.70 to 2.25, p < 0.001) and 1.65 (95% CI: 1.37 to 1.93, p < 0.001), respectively. In both cross-sectional and longitudinal studies, childhood sexual abuse was consistently associated with increased risk of suicide attempts. The findings of the present study provide strong grounds for funding public policy planning and interventions to prevent sexual abuse and support its victims. Areas for future research should include preventive and treatment strategies and factors promoting resilience following childhood sexual abuse. Future research on the subject should have more robust controls and explore the differential effects of gender and intra-versus extra-familial sexual abuse. Copyright © 2018 Elsevier Ltd.

To estimate the present value of current and future funding needed for HIV treatment and prevention in 9 sub-Saharan African (SSA) countries that account for 70% of HIV burden in Africa under different scenarios of intervention scale-up. To analyse the gaps between current expenditures and funding obligation, and discuss the policy implications of future financing needs. We used the Goals module from Spectrum, and applied the most up-to-date cost and coverage data to provide a range of estimates for future financing obligations. The four different scale-up scenarios vary by treatment initiation threshold and service coverage level. We compared the model projections to current domestic and international financial sources available in selected SSA countries. In the 9 SSA countries, the estimated resources required for HIV prevention and treatment in 2015-2050 range from US$98 billion to maintain current coverage levels for treatment and prevention with eligibility for treatment initiation at CD4 count of <500/mm(3) to US$261 billion if treatment were to be extended to all HIV-positive individuals and prevention scaled up. With the addition of new funding obligations for HIV--which arise implicitly through commitment to achieve higher than current treatment coverage levels--overall financial obligations (sum of debt levels and the present value of the stock of future HIV funding obligations) would rise substantially. Investing upfront in scale-up of HIV services to achieve high coverage levels will reduce HIV incidence, prevention and future treatment expenditures by realising long-term preventive effects of ART to reduce HIV transmission. Future obligations are too substantial for most SSA countries to be met from domestic sources alone. New sources of funding, in addition to domestic sources, include innovative financing. Debt sustainability for sustained HIV response is an urgent imperative for affected countries and donors. Published by the BMJ Publishing Group Limited.

Postoperative pancreatic fistula (POPF) is a major, intractable complication after distal pancreatectomy (DP). Risk factor evaluation and prevention of this complication are important tasks for pancreatic surgeons. One hundred and six patients who underwent DP using a stapler for pancreatic division were retrospectively investigated. The relationship between clinicopathological factors and the incidence of POPF was statistically analyzed. Clinically relevant, Grade B or C POPF by International Study Group of Pancreatic Fistula criteria occurred in 52 patients (49.1 %). Age, American Society of Anesthesiologists score, body mass index, and concomitant gastrointestinal tract resection did not influence the incidence of POPF. Use of a double-row stapler and a thick pancreatic stump were significant risk factors for POPF in multivariate analysis. Compression index was also shown to be an important factor in cases in which the pancreas was divided by a stapler. The most important risk factor for POPF after DP was suggested to be the thickness of the pancreatic stump, reflecting the volume of remnant pancreas. A triple-row stapler seemed to be superior to a double-row stapler in preventing POPF. However, triple-row stapler use in a thick pancreas is considered to be a future problem to be solved.

Summary Giardia intestinalis is the leading parasitic aetiology of human enteric infections in the United States, with an estimated 1.2 million cases occurring annually. To better understand transmission, we analysed data on all giardiasis outbreaks reported to the Centers for Disease Control and Prevention for 1971–2011. The 242 outbreaks, affecting ∼41 000 persons, resulted from waterborne (74.8%), foodborne (15.7%), person-to-person (2.5%), and animal contact (1.2%) transmission. Most (74.6%) waterborne outbreaks were associated with drinking water, followed by recreational water (18.2%). Problems with water treatment, untreated groundwater, and distribution systems were identified most often during drinking water-associated outbreak investigations; problems with water treatment declined after the 1980s. Most recreational water-associated outbreaks were linked to treated swimming venues, with pools and wading pools implicated most often. Produce was implicated most often in foodborne outbreaks. Additionally, foods were most commonly prepared in a restaurant and contaminated by a food handler. Lessons learned from examining patterns in outbreaks over time can help prevent future disease. Groundwater and distribution system vulnerabilities, inadequate pool disinfection, fruit and vegetable contamination, and poor food handler hygiene are promising targets for giardiasis prevention measures.

2017-07-15

The etiology of pre-eclampsia (PE) is not yet fully understood, though current literature indicates an upregulation of inflammatory mediators produced by the placenta as a potential causal mechanism. Vitamin D is known to have anti-inflammatory properties and there is evidence of an inverse relationship between dietary calcium intake and the incidence of PE. Evidence of the role of vitamin D status and supplementation in the etiology and prevention of PE is reviewed in this article along with identification of research gaps to inform future studies. We conducted a structured literature search using MEDLINE electronic databases to identify published studies until February 2015. These sources were retrieved, collected, indexed, and assessed for availability of pregnancy-related data on PE and vitamin D. Several case-control studies and cross-sectional studies have shown an association between vitamin D status and PE, although evidence has been inconsistent. Clinical trials to date have been unable to show an independent effect of vitamin D supplementation in preventing PE. The included clinical trials do not show an independent effect of vitamin D supplementation in preventing PE; however, issues with dose, timing, and duration of supplementation have not been completely addressed.

In August 2012, laboratory tests confirmed a mixed outbreak of epidemic typhus fever and trench fever in a male youth rehabilitation center in western Rwanda. Seventy-six suspected cases and 118 controls were enrolled into an unmatched case-control study to identify risk factors for symptomatic illness during the outbreak. A suspected case was fever or history of fever, from April 2012, in a resident of the rehabilitation center. In total, 199 suspected cases from a population of 1,910 male youth (attack rate = 10.4%) with seven deaths (case fatality rate = 3.5%) were reported. After multivariate analysis, history of seeing lice in clothing (adjusted odds ratio [aOR] = 2.6, 95% confidence interval [CI] = 1.1-5.8), delayed (≥ 2 days) washing of clothing (aOR = 4.0, 95% CI = 1.6-9.6), and delayed (≥ 1 month) washing of beddings (aOR = 4.6, 95% CI = 2.0-11) were associated with illness, whereas having stayed in the rehabilitation camp for ≥ 6 months was protective (aOR = 0.20, 95% CI = 0.10-0.40). Stronger surveillance and improvements in hygiene could prevent future outbreaks. © The American Society of Tropical Medicine and Hygiene.

After multivariate analysis, history of seeing lice in clothing (adjusted odds ratio [aOR] = 2.6, 95% confidence interval [CI] = 1.1–5.8), delayed (≥ 2 days) washing of clothing (aOR = 4.0, 95% CI = 1.6–9.6), and delayed (≥ 1 month) washing of beddings (aOR = 4.6, 95% CI = 2.0–11) were associated with illness, whereas having stayed in the rehabilitation camp for ≥ 6 months was protective (aOR = 0.20, 95% CI = 0.10–0.40). Stronger surveillance and improvements in hygiene could prevent future outbreaks. PMID:27352876

Lord, Stephen R; Close, Jacqueline C T

2018-04-25

Falls pose a major threat to the well-being and quality of life of older people. Falls can result in fractures and other injuries, disability and fear and can trigger a decline in physical function and loss of autonomy. This article synthesises recent published findings on fall risk and mobility assessments and fall prevention interventions and considers how this field of research may evolve in the future. Fall risk topics include the utility of remote monitoring using wearable sensors and recent work investigating brain activation and gait adaptability. New approaches for exercise for fall prevention including dual-task training, cognitive-motor training with exergames and reactive step training are discussed. Additional fall prevention strategies considered include the prevention of falls in older people with dementia and Parkinson's disease, drugs for fall prevention and safe flooring for preventing fall-related injuries. The review discusses how these new initiatives and technologies have potential for effective fall prevention and improved quality of life. It concludes by emphasising the need for a continued focus on translation of evidence into practice including robust effectiveness evaluations of so that resources can be appropriately targeted into the future.

Guidelines are increasingly recommending preventive services starting at 50 years of age, and policymakers are considering such a recommendation for pneumococcal polysaccharide vaccination. The finding that pneumococcal vaccination is cost-saving for people 65 years of age or older raises the question of the vaccination's implications for other older adults, especially black people, whose disease incidence exceeds that of nonblack people, and those with high-risk conditions. To assess the implications of vaccinating black and nonblack people 50 through 64 years of age against invasive pneumococcal disease. Cost-effectiveness analysis. Published literature for vaccination effectiveness and cost estimates; data on disease incidence and case-fatality rates from the Centers for Disease Control and Prevention. Hypothetical cohort 50 through 64 years of age with the 1995 U.S. age distribution. Lifetime. Societal. Pneumococcal polysaccharide vaccination compared with no vaccination. Incremental medical costs and health effects, in quality-adjusted life-years per vaccinee. Vaccination saved medical costs and improved health among high-risk black people (27.55 dollars savings per vaccinee) and nonblack people (5.92 dollars savings per vaccinee), excluding survivors' future costs. For low-risk black and nonblack people and the overall general population, vaccination cost 2477 dollars, 8195 dollars, and 3434 dollars, respectively, to gain 1 year of healthy life. Excluding survivors' future costs, in the general immunocompetent population, cost per quality-adjusted life-year in global worst-case results ranged from 21 513 dollars for black people to 68 871 dollars for nonblack people; in the high-risk population, cost ranged from 11 548 dollars for black people to 39 000 dollars for nonblack people. In the global best case, vaccination was cost-saving for black and nonblack people in the general immunocompetent and high-risk populations, excluding survivors' future costs. The cost-effectiveness range was narrower in probabilistic sensitivity analyses, with 95% probabilistic intervals ranging from cost-saving to 1594 dollars for black people and from cost-saving to 12 273 dollars for nonblack people in the general immunocompetent population. Costs per quality-adjusted life-year for low-risk people with case-fatality rates from 1998 were 2477 dollars for black people and 8195 dollars for nonblack people, excluding survivors' medical costs. These results support the current recommendation to vaccinate high-risk people and provide useful information for considering extending the recommendation to the general population 50 through 64 years of age. Lack of evidence about the effectiveness of revaccination for people 65 years of age or older, when disease risks are higher, argues for further research to guide vaccination policy.

multifactorial falls prevention programmes for older people have been proved to reduce falls. However, evidence of their cost-effectiveness is mixed. economic evaluation alongside pragmatic randomised controlled trial. randomised trial of 364 people aged ≥70, living in the community, recruited via GP and identified as high risk of falling. Both arms received a falls prevention information leaflet. The intervention arm were also offered a (day hospital) multidisciplinary falls prevention programme, including physiotherapy, occupational therapy, nurse, medical review and referral to other specialists. self-reported falls, as collected in 12 monthly diaries. Levels of health resource use associated with the falls prevention programme, screening (both attributed to intervention arm only) and other health-care contacts were monitored. Mean NHS costs and falls per person per year were estimated for both arms, along with the incremental cost-effectiveness ratio (ICER) and cost effectiveness acceptability curve. in the base-case analysis, the mean falls programme cost was £349 per person. This, coupled with higher screening and other health-care costs, resulted in a mean incremental cost of £578 for the intervention arm. The mean falls rate was lower in the intervention arm (2.07 per person/year), compared with the control arm (2.24). The estimated ICER was £3,320 per fall averted. the estimated ICER was £3,320 per fall averted. Future research should focus on adherence to the intervention and an assessment of impact on quality of life.

Prevention of late-life depression, a common, disabling condition with often poor outcomes in primary care, requires identification of seniors at highest risk of incident episodes. The authors examined a broad range of clinical, functional, and psychosocial predictors of incident depressive episodes in a well-characterized cohort of older primary care patients. In this observational cohort study, patients age >/=65 years without current major depression, recruited from practices in general internal medicine, geriatrics, and family medicine, received annual follow-up assessments over a period of 1 to 4 years. Of 617 enrolled subjects, 405 completed the 1-year follow-up evaluation. The Structured Clinical Interview for DSM-IV (SCID) determined incident major depressive episodes. Each risk indicator's predictive utility was examined by calculating the risk exposure rate, incident risk ratio, and population attributable fraction, leading to determination of the number needed to treat in order to prevent incident depression. A combination of risks, including minor or subsyndromal depression, impaired functional status, and history of major or minor depression, identified a group in which fully effective treatment of five individuals would prevent one new case of incident depression. Indicators routinely assessed in primary care identified a group at very high risk for onset of major depressive episodes. Such markers may inform current clinical care by fostering the early detection and intervention critical to improving patient outcomes and may serve as the basis for future studies refining the recommendations for screening and determining the effectiveness of preventive interventions.

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.

Autophagy regulating kinases as potential therapeutic targets for age-related macular degeneration.

2012-11-01

Age-related macular degeneration (AMD) is the leading cause of central vision loss in the elderly in the developed countries. The number of AMD patients will double during the next decades due to increasing number of aged people. Chronic oxidative stress, inflammation and accumulation of protein-rich deposits both in the retinal pigment epithelium lysosomes and under the retinal pigment epithelium herald the onset of AMD. The disease can be divided into dry and wet AMD forms. The dry form of the disease is more prevalent accounting for up to 90% of all cases. Continued intraocular injections are the current treatment strategy to prevent progression of wet AMD. It is a major challenge to develop new drugs that could prevent or at least ease the symptoms of the increasing population of AMD patients. Since AMD pathology is clearly associated with accumulated protein deposits, the autophagy clearance system might represent a potential future therapeutic target for AMD as is thoroughly discussed here.

The extreme danger associated with entering enclosed spaces loaded with oxygen-depleting organic cargo in ships and tanks is obviously underestimated, both among crew and management. We present a case report to highlight this occupational hazard and to increase the knowledge about the imperative precautions, in order to prevent future accidents. An experienced customs officer was found lifeless at the bottom of the unattended cargo hold on a ship loaded with woodchips. The oxygen content in the cargo atmosphere was below 2%, which is incompatible with life. Forensic autopsy revealed injuries related to the fall, and there were no positive toxicological findings in blood, lung or urine. Management and workers must be taught about the extreme rapidity of developing unconsciousness and asphyxiant death when entering enclosed spaces loaded with oxygen-depleting cargo. Even a single inhalation can result in unconsciousness and death. Dozens of annual deaths and severe injuries can easily be prevented if simple precautions are followed.

This study evaluated the impact on childhood lead poisoning of a primary-prevention educational-intervention program for pregnant women in St. Louis, Missouri. The women were predominantly poor and of African-American, Hispanic, Asian, and Caucasian backgrounds. The interventions, tailored for each woman on the basis of responses to a survey and environmental measurements, included case management with hands-on instruction on cleaning techniques, property maintenance, hygiene, and nutrition to reduce exposure of newborns to lead. It was hypothesized that the probability of lead poisoning (blood lead levels greater than 10 microg/dL) would be reduced among mothers who received the interventions compared with those who received only printed educational material. Contrary to expectations, none of the interventions reduced the likelihood of lead poisoning among participating children. In the process of the study, however, a number of valuable lessons related to recruitment and commitment of participants emerged that can inform future efforts of this nature.

Objective This study aimed to build formative knowledge on socio-structural barriers, protective factors, and HIV sexual risk amongst Central-Asian female migrants in Moscow. Methods Data collection included ethnographic interviews in Moscow with a purposive sample of 30 unmarried female migrants, 15 from Kyrgyzstan and 15 from Tajikistan. Results Study participants reported difficulties with acquiring documents for legal status, financial insecurity, discrimination, sexual harassment, and lack of support. Based on analysis of the cases, one pathway linked lack of legal documentation and instrumental support with elevated sexual risk. Another pathways linked traditional cultural attitudes with both no and moderate sexual risk. Conclusion Future HIV prevention efforts with Central Asian female migrants in Moscow should be multilevel and include: increasing HIV and prevention knowledge and skills, promoting condom use with regular partners, identifying and supporting cultural attitudes that protect against HIV sexual risk behaviors, facilitating legal status, building community support, and increasing economic options.

Gene Patents and Personalized Cancer Care: Impact of the Myriad Case on Clinical Oncology

2013-01-01

Genomic discoveries have transformed the practice of oncology and cancer prevention. Diagnostic and therapeutic advances based on cancer genomics developed during a time when it was possible to patent genes. A case before the Supreme Court, Association for Molecular Pathology v Myriad Genetics, Inc seeks to overturn patents on isolated genes. Although the outcomes are uncertain, it is suggested here that the Supreme Court decision will have few immediate effects on oncology practice or research but may have more significant long-term impact. The Federal Circuit court has already rejected Myriad's broad diagnostic methods claims, and this is not affected by the Supreme Court decision. Isolated DNA patents were already becoming obsolete on scientific grounds, in an era when human DNA sequence is public knowledge and because modern methods of next-generation sequencing need not involve isolated DNA. The Association for Molecular Pathology v Myriad Supreme Court decision will have limited impact on new drug development, as new drug patents usually involve cellular methods. A nuanced Supreme Court decision acknowledging the scientific distinction between synthetic cDNA and genomic DNA will further mitigate any adverse impact. A Supreme Court decision to include or exclude all types of DNA from patent eligibility could impact future incentives for genomic discovery as well as the future delivery of medical care. Whatever the outcome of this important case, it is important that judicial and legislative actions in this area maximize genomic discovery while also ensuring patients' access to personalized cancer care.

In 2014, the Centers for Disease Control and Prevention funded the American Heart Association to implement policy, systems, and environment-focused strategies targeting access to healthy food and beverages, physical activity, and smoke-free environments. To understand factors affecting implementation and variations in success across sites, evaluators conducted a multiple case study. Based on past literature, community sites were categorized as capacity-building or implementation-ready, for comparison. A sample of six communities were selected using a systematic selection tool. Through site visits, evaluators conducted interviews with program staff and community partners and assessed action plans. Evaluators identified important implications for nationally coordinated community-based prevention programming. Differences in implementation varied by the communities' readiness, with the most notable differences in how they planned activities and defined success. Existing partner relationships (or lack thereof) played a significant role, regardless of the American Heart Association's existing presence within the communities, in the progression of initiatives and the differences observed among phases. Last, goals in capacity-building sites were tied to organizational goals while goals in implementation-ready sites were more incremental with increased community influence and buy-in. Using national organizations as a mechanism to carry out large-scale community-based prevention work is a viable option that provides coordinated, wide-scale implementation without sacrificing a community's priorities or input. In funding future initiatives, the presence of relationships and the time needed to cultivate such relationships should be accounted for in the planning and implementation processes, as well as both local and national expectations.

To estimate the number of coronary heart disease (CHD) deaths potentially preventable in England in 2020 comparing four risk factor change scenarios. Using 2007 as baseline, the IMPACTSEC model was extended to estimate the potential number of CHD deaths preventable in England in 2020 by age, gender and Index of Multiple Deprivation 2007 quintiles given four risk factor change scenarios: (a) assuming recent trends will continue; (b) assuming optimal but feasible levels already achieved elsewhere; (c) an intermediate point, halfway between current and optimal levels; and (d) assuming plateauing or worsening levels, the worst case scenario. These four scenarios were compared to the baseline scenario with both risk factors and CHD mortality rates remaining at 2007 levels. This would result in approximately 97,000 CHD deaths in 2020. Assuming recent trends will continue would avert approximately 22,640 deaths (95% uncertainty interval: 20,390-24,980). There would be some 39,720 (37,120-41,900) fewer deaths in 2020 with optimal risk factor levels and 22,330 fewer (19,850-24,300) in the intermediate scenario. In the worst case scenario, 16,170 additional deaths (13,880-18,420) would occur. If optimal risk factor levels were achieved, the gap in CHD rates between the most and least deprived areas would halve with falls in systolic blood pressure, physical inactivity and total cholesterol providing the largest contributions to mortality gains. CHD mortality reductions of up to 45%, accompanied by significant reductions in area deprivation mortality disparities, would be possible by implementing optimal preventive policies.

Candida species are the leading cause of invasive fungal infections in hospitalized children and are the third most common isolates recovered from patients with healthcare-associated bloodstream infection in the United States. Few data exist on risk factors for candidemia in pediatric intensive care unit (PICU) patients. We conducted a population-based case-control study of PICU patients at Children's Hospital of Philadelphia during the period from 1997 through 2004. Case patients were identified using laboratory records, and control patients were selected from PICU rosters. Control patients were matched to case patients by incidence density sampling, adjusting for time at risk. Following conditional multivariate analysis, we performed weighted multivariate analysis to determine predicted probabilities for candidemia given certain risk factor combinations. We identified 101 case patients with candidemia (incidence, 3.5 cases per 1000 PICU admissions). Factors independently associated with candidemia included presence of a central venous catheter (odds ratio [OR], 30.4; 95% confidence interval [CI], 7.7-119.5), malignancy (OR, 4.0; 95% CI, 1.23-13.1), use of vancomycin for >3 days in the prior 2 weeks (OR, 6.2; 95% CI, 2.4-16), and receipt of agents with activity against anaerobic organisms for >3 days in the prior 2 weeks (OR, 3.5; 95% CI, 1.5-8.4). Predicted probability of having various combinations of the aforementioned factors ranged from 10.7% to 46%. The 30-day mortality rate was 44% among case patients and 14% among control patients (OR, 4.22; 95% CI, 2.35-7.60). To our knowledge, this is the first study to evaluate independent risk factors and to determine a population of children in PICUs at high risk for developing candidemia. Future efforts should focus on validation of these risk factors identified in a different PICU population and development of interventions for prevention of candidemia in critically ill children.

Using mobile devices, such as personal digital assistants (PDAs), smartphones, tablet computers, etc., to electronically collect malaria-related field data is the way for the field questionnaires in the future. This case study seeks to design a generic survey framework PDA-based geo-tagged malaria-related data collection tool (PGMS) that can be used not only for large-scale community-level geo-tagged electronic malaria-related surveys, but also for a wide variety of electronic data collections of other infectious diseases. The framework includes two parts: the database designed for subsequent cross-sectional data analysis and the customized programs for the six study sites (two in Kenya, three in Indonesia, and one in Tanzania). In addition to the framework development, we also present our methods used when configuring and deploying the PDAs to 1) reduce data entry errors, 2) conserve battery power, 3) field install the programs onto dozens of handheld devices, 4) translate electronic questionnaires into local languages, 5) prevent data loss, and 6) transfer data from PDAs to computers for future analysis and storage. Since 2008, PGMS has successfully accomplished quite a few surveys that recorded 10,871 compounds and households, 52,126 persons, and 17,100 bed nets from the six sites. These numbers are still growing. PMID:25048377

Has Rift Valley fever virus evolved with increasing severity in human populations in East Africa?

Baba, Marycelin; Masiga, Daniel K; Sang, Rosemary; Villinger, Jandouwe

2016-06-22

Rift Valley fever (RVF) outbreaks have occurred across eastern Africa from 1912 to 2010 approximately every 4-15 years, most of which have not been accompanied by significant epidemics in human populations. However, human epidemics during RVF outbreaks in eastern Africa have involved 478 deaths in 1998, 1107 reported cases with 350 deaths from 2006 to 2007 and 1174 cases with 241 deaths in 2008. We review the history of RVF outbreaks in eastern Africa to identify the epidemiological factors that could have influenced its increasing severity in humans. Diverse ecological factors influence outbreak frequency, whereas virus evolution has a greater impact on its virulence in hosts. Several factors could have influenced the lack of information on RVF in humans during earlier outbreaks, but the explosive nature of human RVF epidemics in recent years mirrors the evolutionary trend of the virus. Comparisons between isolates from different outbreaks have revealed an accumulation of genetic mutations and genomic reassortments that have diversified RVF virus genomes over several decades. The threat to humans posed by the diversified RVF virus strains increases the potential public health and socioeconomic impacts of future outbreaks. Understanding the shifting RVF epidemiology as determined by its evolution is key to developing new strategies for outbreak mitigation and prevention of future human RVF casualties.

Modelling the cost-effectiveness of a new infant vaccine to prevent tuberculosis disease in children in South Africa

PubMed Central

2014-01-01

Background Tuberculosis remains the leading cause of death in South Africa. A number of potential new TB vaccine candidates have been identified and are currently in clinical trials. One such candidate is MVA85A. This study aimed to estimate the cost-effectiveness of adding the MVA85A vaccine as a booster to the BCG vaccine in children from the perspective of the South African government. Methods The cost-effectiveness was assessed by employing Decision Analytic Modelling, through the use of a Markov model. The model compared the existing strategy of BCG vaccination to a new strategy in which infants receive BCG and a booster vaccine, MVA85A, at 4 months of age. The costs and outcomes of the two strategies are estimated through modelling the vaccination of a hypothetical cohort of newborns and following them from birth through to 10 years of age, employing 6-monthly cycles. Results The results of the cost-effectiveness analysis indicate that the MVA85A strategy is both more costly and more effective – there are fewer TB cases and deaths from TB than BCG alone. The South African government would need to spend an additional USD 1,105 for every additional TB case averted and USD 284,017 for every additional TB death averted. The threshold analysis shows that, if the efficacy of the MVA85A vaccine was 41.3% (instead of the current efficacy of 17.3%), the two strategies would have the same cost but more cases of TB and more deaths from TB would be prevented by adding the MVA85A vaccine to the BCG vaccine. In this case, the government chould consider the MVA85A strategy. Conclusions At the current level of efficacy, the MVA85A vaccine is neither effective nor cost-effective and, therefore, not a good use of limited resources. Nevertheless, this study contributes to developing a standardized Markov model, which could be used, in the future, to estimate the potential cost-effectiveness of new TB vaccines compared to the BCG vaccine, in children between the ages of 0–10 years. It also provides an indicative threshold of vaccine efficacy, which could guide future development. PMID:25242892

Background: Skull base tumors frequently encase or invade adjacent normal neurovascular structures. For this reason, optimal tumor resection with incomplete knowledge of patient anatomy remains a challenge. Methods: To determine the accuracy and utility of image-based preoperative segmentation in skull base tumor resections, we performed a prospective study. Ten patients with skull base tumors underwent preoperative 3T magnetic resonance imaging, which included thin section three-dimensional (3D) space T2, 3D time of flight, and magnetization-prepared rapid acquisition gradient echo sequences. Imaging sequences were loaded in the neuronavigation system for segmentation and preoperative planning. Five different neurovascular landmarks were identified in each case and measured for accuracy using the neuronavigation system. Each segmented neurovascular element was validated by manual placement of the navigation probe, and errors of localization were measured. Results: Strong correspondence between image-based segmentation and microscopic view was found at the surface of the tumor and tumor-normal brain interfaces in all cases. The accuracy of the measurements was 0.45 ± 0.21 mm (mean ± standard deviation). This information reassured the surgeon and prevented vascular injury intraoperatively. Preoperative segmentation of the related cranial nerves was possible in 80% of cases and helped the surgeon localize involved cranial nerves in all cases. Conclusion: Image-based preoperative vascular and neural element segmentation with 3D reconstruction is highly informative preoperatively and could increase the vigilance of neurosurgeons for preventing neurovascular injury during skull base surgeries. Additionally, the accuracy found in this study is superior to previously reported measurements. This novel preliminary study is encouraging for future validation with larger numbers of patients.

Self-harm is a leading cause of morbidity and mortality. Exposure to community violence is an important and potentially modifiable feature of the social environment that may affect self-harm, but studies to date are limited in the samples and outcomes examined. We conducted a population-based, nested case-control study. Cases were all deaths and hospital visits due to self-harm in California, 2006-2013. We frequency-matched California resident population-based controls from the American Community Survey to cases on age, gender, race/ethnicity, and year of survey/injury. We assessed past-year community violence using deaths and hospital visits due to interpersonal violence in the community of residence. We estimated risk-difference parameters that were defined to avoid extrapolation and to capture associations between changes in the distribution of community violence and the population-level risk of self-harm. After adjustment for confounders, setting past-year community violence to the lowest monthly levels observed within each community over the study period was associated with a 30.1 (95% CI: 29.6 to 30.5) per 100,000 persons per year lower risk of nonfatal self-harm, but no difference in the risk of fatal self-harm. Associations for a parameter corresponding to a hypothetical violence prevention intervention targeting high-violence communities indicated a 5% decrease in self-harm at the population level. In sensitivity analyses, results were robust. This study strengthens evidence on the relationship between community violence and self-harm. Future research should investigate reasons for differential associations by age and gender and whether community violence prevention programs have meaningful impacts on self-harm.

Helicobacter Pylori “Test-and-Treat” Strategy for Management of Dyspepsia: A Comprehensive Review

Gisbert, Javier P; Calvet, Xavier

2013-01-01

OBJECTIVES: Deciding on whether the Helicobacter pylori test-and-treat strategy is an appropriate diagnostic–therapeutic approach for patients with dyspepsia invites a series of questions. The aim present article addresses the test-and-treat strategy and attempts to provide practical conclusions for the clinician who diagnoses and treats patients with dyspepsia. METHODS: Bibliographical searches were performed in MEDLINE using the keywords Helicobacter pylori, test-and-treat, and dyspepsia. We focused mainly on data from randomized controlled trials (RCTs), systematic reviews, meta-analyses, cost-effectiveness analyses, and decision analyses. RESULTS: Several prospective studies and decision analyses support the use of the test-and-treat strategy, although we must be cautious when extrapolating the results from one geographical area to another. Many factors determine whether this strategy is appropriate in each particular area. The test-and-treat strategy will cure most cases of underlying peptic ulcer disease, prevent most potential cases of gastroduodenal disease, and yield symptomatic benefit in a minority of patients with functional dyspepsia. Future studies should be able to stratify dyspeptic patients according to their likelihood of improving after treatment of infection by H. pylori. CONCLUSIONS: The test-and-treat strategy will cure most cases of underlying peptic ulcer disease and prevent most potential cases of gastroduodenal disease. In addition, a minority of infected patients with functional dyspepsia will gain symptomatic benefit. Several prospective studies and decision analyses support the use of the test-and-treat strategy. The test-and-treat strategy is being reinforced by the accumulating data that support the increasingly accepted idea that “the only good H. pylori is a dead H. pylori”. PMID:23535826

Outbreak of Serratia marcescens bloodstream infections in patients receiving parenteral nutrition prepared by a compounding pharmacy.

Compounding pharmacies often prepare parenteral nutrition (PN) and must adhere to rigorous standards to avoid contamination of the sterile preparation. In March 2011, Serratia marcescens bloodstream infections (BSIs) were identified in 5 patients receiving PN from a single compounding pharmacy. An investigation was conducted to identify potential sources of contamination and prevent further infections. Cases were defined as S. marcescens BSIs in patients receiving PN from the pharmacy between January and March 2011. We reviewed case patients' clinical records, evaluated pharmacy compounding practices, and obtained epidemiologically directed environmental cultures. Molecular relatedness of available Serratia isolates was determined by pulsed-field gel electrophoresis (PFGE). Nineteen case patients were identified; 9 died. The attack rate for patients receiving PN in March was 35%. No case patients were younger than 18 years. In October 2010, the pharmacy began compounding and filter-sterilizing amino acid solution for adult PN using nonsterile amino acids due to a national manufacturer shortage. Review of this process identified breaches in mixing, filtration, and sterility testing practices. S. marcescens was identified from a pharmacy water faucet, mixing container, and opened amino acid powder. These isolates were indistinguishable from the outbreak strain by PFGE. Compounding of nonsterile amino acid components of PN was initiated due to a manufacturer shortage. Failure to follow recommended compounding standards contributed to an outbreak of S. marcescens BSIs. Improved adherence to sterile compounding standards, critical examination of standards for sterile compounding from nonsterile ingredients, and more rigorous oversight of compounding pharmacies is needed to prevent future outbreaks.

Distributional dynamics of a vulnerable species in response to past and future climate change: a window for conservation prospects

2018-01-01

Background The ongoing change in climate is predicted to exert unprecedented effects on Earth’s biodiversity at all levels of organization. Biological conservation is important to prevent biodiversity loss, especially for species facing a high risk of extinction. Understanding the past responses of species to climate change is helpful for revealing response mechanisms, which will contribute to the development of effective conservation strategies in the future. Methods In this study, we modelled the distributional dynamics of a ‘Vulnerable’ species, Pseudolarix amabilis, in response to late Quaternary glacial-interglacial cycles and future 2080 climate change using an ecological niche model (MaxEnt). We also performed migration vector analysis to reveal the potential migration of the population over time. Results Historical modelling indicates that the range dynamics of P. amabilis is highly sensitive to climate change and that its long-distance dispersal ability and potential for evolutionary adaption are limited. Compared to the current climatically suitable areas for this species, future modelling showed significant migration northward towards future potential climatically suitable areas. Discussion In combination with the predicted future distribution, the mechanism revealed by the historical response suggests that this species will not be able to fully occupy the future expanded areas of suitable climate or adapt to the unsuitable climate across the future contraction regions. As a result, we suggest assisted migration as an effective supplementary means of conserving this vulnerable species in the face of the unprecedentedly rapid climate change of the 21st century. As a study case, this work highlights the significance of introducing historical perspectives while researching species conservation, especially for currently vulnerable or endangered taxa that once had a wider distribution in geological time.

[Role of the social support network which influences age of death and physical function of elderly people: study of trends in and outside of Japan and future problems].

Concerning associations between the social support network and physical health of the elderly, longitudinal studies have been conducted using various measurement indexes. The studies indicated that the support network influences on physical function and life expectancy. In this study we compared research papers from Japan and elsewhere that appeared after 1980, from the viewpoint of 1) social support effects, and 2) social network effects, to examine potential problems in the future. The main knowledge obtained was that the receipt of emotional support, wide network size, and participation in social activities reduced the risk of early death and decrease in physical function of elderly people. Sex differences were indicated, and in many cases, the effects were more remarkable in men than women. In addition the positive influence of receiving help from a support network, a major subject of conventional research, the effects of offering help to others and negative findings were also examined. It has been indicated that participation in volunteer groups and offer of support to other people can prevent decrease in physical function or early death. As negative effects, improper instrumental support rather disturbs the mental and physical independence of elderly people. As future issues, it is necessary to focus on both positive/negative and receipt/offer effects of support network, and to clarify how to provide example which best match the life of elderly people by comparing sexes and regions. It is also important to actually apply the knowledge gained from observational studies to prevent the elderly from becoming a condition requiring care, and to develop intervention studies which can increase the social contacts of elderly people at the same time as conducting health education and medical treatment.

Mobile technologies are a useful platform for the delivery of health behavior interventions. Yet little work has been done to create a rigorous and standardized process for the design of mobile health (mHealth) apps. This project sought to explore the use of the Information Systems Research (ISR) framework as guide for the design of mHealth apps. Our work was guided by the ISR framework which is comprised of 3 cycles: Relevance, Rigor and Design. In the Relevance cycle, we conducted 5 focus groups with 33 targeted end-users. In the Rigor cycle, we performed a review to identify technology-based interventions for meeting the health prevention needs of our target population. In the Design Cycle, we employed usability evaluation methods to iteratively develop and refine mock-ups for a mHealth app. Through an iterative process, we identified barriers and facilitators to the use of mHealth technology for HIV prevention for high-risk MSM, developed 'use cases' and identified relevant functional content and features for inclusion in a design document to guide future app development. Findings from our work support the use of the ISR framework as a guide for designing future mHealth apps. Results from this work provide detailed descriptions of the user-centered design and system development and have heuristic value for those venturing into the area of technology-based intervention work. Findings from this study support the use of the ISR framework as a guide for future mHealth app development. Use of the ISR framework is a potentially useful approach for the design of a mobile app that incorporates end-users' design preferences. Copyright © 2016 Elsevier Inc. All rights reserved.

Productivity losses associated with tuberculosis deaths in the World Health Organization African region.

Kirigia, Joses Muthuri; Muthuri, Rosenabi Deborah Karimi

2016-06-01

In 2014, almost half of the global tuberculosis deaths occurred in the World Health Organization (WHO) African Region. Approximately 21.5 % of the 6 060 742 TB cases (new and relapse) reported to the WHO in 2014 were in the African Region. The specific objective of this study was to estimate future gross domestic product (GDP) losses associated with TB deaths in the African Region for use in advocating for better strategies to prevent and control tuberculosis. The cost-of-illness method was used to estimate non-health GDP losses associated with TB deaths. Future non-health GDP losses were discounted at 3 %. The analysis was conducted for three income groups of countries. One-way sensitivity analysis at 5 and 10 % discount rates was undertaken to assess the impact on the expected non-health GDP loss. The 0.753 million tuberculosis deaths that occurred in the African Region in 2014 would be expected to decrease the future non-health GDP by International Dollars (Int$) 50.4 billion. Nearly 40.8, 46.7 and 12.5 % of that loss would come from high and upper-middle- countries or lower-middle- and low-income countries, respectively. The average total non-health GDP loss would be Int$66 872 per tuberculosis death. The average non-health GDP loss per TB death was Int$167 592 for Group 1, Int$69 808 for Group 2 and Int$21 513 for Group 3. Tuberculosis exerts a sizeable economic burden on the economies of the WHO AFR countries. This implies the need to strongly advocate for better strategies to prevent and control tuberculosis and to help countries end the epidemic of tuberculosis by 2030, as envisioned in the United Nations General Assembly resolution on Sustainable Development Goals (SDGs).

The aims of this study were to determine the patterns of analgesic adverse drug reactions (ADRs) and to assess their preventability and contributing factors. This is a retrospective, descriptive study conducted on ADRs of analgesics and other drugs indicated as analgesics, spontaneously reported to the Bordeaux pharmacovigilance center from January 2011 to June 2012. The 141 cases selected for the analysis included 16 cases of medication errors (11.3%) and 15 addiction cases (10.6%). In total, 214 ADRs were registered, for which 173 analgesic medicines were suspected. The most frequent ADRs reported were nervous system disorders (26.6%), psychiatric disorders (15.0%), and skin and subcutaneous tissue disorders (12.1%). Tramadol alone or in combination (17.3%), followed by morphine (15%), fentanyl (9.8%), and paracetamol (8.7%) were the most frequently involved analgesics. More than half of the cases (54.6%) were serious and led to hospitalization or prolonged hospitalization. Preventability was determined for 134 cases (95%): 51.5% were considered as preventable, 26.1% not preventable, and 22.4% not assessable. The main contributing factors for the preventable cases included negligence of recommendations for analgesic use and failure to consider patients' risk factors when prescribing. A significant number of analgesic ADRs could be prevented, and being aware of their contributing factors promotes efficient analgesia with minimum risks to the patients.

Estimating the future number of cases in the Ebola epidemic--Liberia and Sierra Leone, 2014-2015.

The first cases of the current West African epidemic of Ebola virus disease (hereafter referred to as Ebola) were reported on March 22, 2014, with a report of 49 cases in Guinea. By August 31, 2014, a total of 3,685 probable, confirmed, and suspected cases in West Africa had been reported. To aid in planning for additional disease-control efforts, CDC constructed a modeling tool called EbolaResponse to provide estimates of the potential number of future cases. If trends continue without scale-up of effective interventions, by September 30, 2014, Sierra Leone and Liberia will have a total of approximately 8,000 Ebola cases. A potential underreporting correction factor of 2.5 also was calculated. Using this correction factor, the model estimates that approximately 21,000 total cases will have occurred in Liberia and Sierra Leone by September 30, 2014. Reported cases in Liberia are doubling every 15-20 days, and those in Sierra Leone are doubling every 30-40 days. The EbolaResponse modeling tool also was used to estimate how control and prevention interventions can slow and eventually stop the epidemic. In a hypothetical scenario, the epidemic begins to decrease and eventually end if approximately 70% of persons with Ebola are in medical care facilities or Ebola treatment units (ETUs) or, when these settings are at capacity, in a non-ETU setting such that there is a reduced risk for disease transmission (including safe burial when needed). In another hypothetical scenario, every 30-day delay in increasing the percentage of patients in ETUs to 70% was associated with an approximate tripling in the number of daily cases that occur at the peak of the epidemic (however, the epidemic still eventually ends). Officials have developed a plan to rapidly increase ETU capacities and also are developing innovative methods that can be quickly scaled up to isolate patients in non-ETU settings in a way that can help disrupt Ebola transmission in communities. The U.S. government and international organizations recently announced commitments to support these measures. As these measures are rapidly implemented and sustained, the higher projections presented in this report become very unlikely.

Are Genetic Tests for Atherosclerosis Ready for Routine Clinical Use?

PubMed

Paynter, Nina P; Ridker, Paul M; Chasman, Daniel I

2016-02-19

In this review, we lay out 3 areas currently being evaluated for incorporation of genetic information into clinical practice related to atherosclerosis. The first, familial hypercholesterolemia, is the clearest case for utility of genetic testing in diagnosis and potentially guiding treatment. Already in use for confirmatory testing of familial hypercholesterolemia and for cascade screening of relatives, genetic testing is likely to expand to help establish diagnoses and facilitate research related to most effective therapies, including new agents, such as PCSK9 inhibitors. The second area, adding genetic information to cardiovascular risk prediction for primary prevention, is not currently recommended. Although identification of additional variants may add substantially to prediction in the future, combining known variants has not yet demonstrated sufficient improvement in prediction for incorporation into commonly used risk scores. The third area, pharmacogenetics, has utility for some therapies today. Future utility for pharmacogenetics will wax or wane depending on the nature of available drugs and therapeutic strategies. © 2016 American Heart Association, Inc.

Noninflammatory Joint Contractures Arising from Immobility: Animal Models to Future Treatments

Wong, Kayleigh; Trudel, Guy; Laneuville, Odette

2015-01-01

Joint contractures, defined as the limitation in the passive range of motion of a mobile joint, can be classified as noninflammatory diseases of the musculoskeletal system. The pathophysiology is not well understood; limited information is available on causal factors, progression, the pathophysiology involved, and prediction of response to treatment. The clinical heterogeneity of joint contractures combined with the heterogeneous contribution of joint connective tissues to joint mobility presents challenges to the study of joint contractures. Furthermore, contractures are often a symptom of a wide variety of heterogeneous disorders that are in many cases multifactorial. Extended immobility has been identified as a causal factor and evidence is provided from both experimental and epidemiology studies. Of interest is the involvement of the joint capsule in the pathophysiology of joint contractures and lack of response to remobilization. While molecular pathways involved in the development of joint contractures are being investigated, current treatments focus on physiotherapy, which is ineffective on irreversible contractures. Future treatments may include early diagnosis and prevention. PMID:26247029

Infertility has become a major health issue in the world. It affects the social life of couples and of all infertility cases; approximately 40–50% is due to “male factor” infertility. Male infertility could be due to genetic factors, environment or due to gonadotoxic treatment. Developments in reproductive biotechnology have made it possible to rescue fertility and uphold biological fatherhood. In vitro production of haploid male germ cell is a powerful tool, not only for the treatment of infertility including oligozoospermic or azoospermic patient, but also for the fertility preservation in pre-pubertal boys whose gonadal function is threatened by gonadotoxic therapies. Genomic editing of in-vitro cultured germ cells could also potentially cure flaws in spermatogenesis due to genomic mutation. Furthermore, this ex-vivo maturation technique with genomic editing may be used to prevent paternal transmission of genomic diseases. Here, we summarize the historical progress of in vitro spermatogenesis research by using organ and cell culture techniques and the future clinical application of in vitro spermatogenesis.

2009-01-01

Influenza A subtype H7 viruses have resulted in >100 cases of human infection since 2002 in the Netherlands, Italy, Canada, the United States, and the United Kingdom. Clinical illness from subtype H7 infection ranges from conjunctivitis to mild upper respiratory illness to pneumonia. Although subtype H7 infections have resulted in a smaller proportion of hospitalizations and deaths in humans than those caused by subtype H5N1, some subtype H7 strains appear more adapted for human infection on the basis of their virus-binding properties and illness rates among exposed persons. Moreover, increased isolation of subtype H7 influenza viruses from poultry and the ability of this subtype to cause severe human disease underscore the need for continued surveillance and characterization of these viruses. We review the history of human infection caused by subtype H7. In addition, we discuss recently identified molecular correlates of subtype H7 virus pathogenesis and assess current measures to prevent future subtype H7 virus infection. PMID:19523282

Ebola virus can cause severe hemorrhagic disease with high fatality rates. Currently, no specific therapeutic agent or vaccine has been approved for treatment and prevention of Ebola virus infection of humans. Although the number of Ebola cases has fallen in the last few weeks, multiple outbreaks of Ebola virus infection and the likelihood of future exposure highlight the need for development and rapid evaluation of pre- and postexposure treatments. Here, we briefly review the existing and future options for anti-Ebola therapy, based on the data coming from rare clinical reports, studies on animals, and results from in vitro models. We also project the mechanistic hypotheses of several potential drugs against Ebola virus, including small-molecule-based drugs, which are under development and being tested in animal models or in vitro using various cell types. Our paper discusses strategies toward identifying and testing anti-Ebola virus properties of known and medically approved drugs, especially those that can limit the pathological inflammatory response in Ebola patients and thereby provide protection from mortality. We underline the importance of developing combinational therapy for better treatment outcomes for Ebola patients. Copyright © 2015, American Society for Microbiology. All Rights Reserved.

Policy strategies for injury and violence prevention influence systems development, organizational change, social norms, and individual behavior to improve the health and safety of a population. Injury and violence prevention professionals should consider how their issues resonate with various audiences, including policy makers, the public, and other decision makers. As the cost of healthcare continues to rise and greater demands are placed on the healthcare system, the use of public health policy becomes increasingly critical to protect the public's health and prevent injury and violence and its related morbidities and disabilities (Degutis, 2011). This article highlights some impactful policy successes from the field, allows us to reflect on the Injury Center's 20th anniversary, and describes steps to address injuries and violence into the future. The purpose of this paper is to discuss policy as a public health strategy and the critical role it plays in injury and violence prevention. Published by Elsevier Ltd.

Outcomes of interest are common child and adolescent mental disorders including hyperactive, behavioral and emotional disorders. This literature suggests that the preconception and perinatal periods offer important opportunities for the prevention of deleterious fetal exposures. As such, the perinatal period is a critical period where future mental health prevention efforts should be focused and prevention models developed. Interventions grounded in evidence-based recommendations for the perinatal period could take the form of public health, universal and more targeted interventions. If successful, such interventions are likely to have lifelong effects on (mental) health. PMID:24559477

African American young men who have sex with men and transgender persons are at elevated risk for HIV infection. House and Ball communities, networks of mostly African American gay, bisexual and transgender individuals who compete in modeling and dance, represent a prime venue for HIV prevention with these difficult-to-reach populations; however, little research exists on effective approaches to HIV prevention within these communities. Using a mixed-methods approach, the present study sought to document participation in HIV prevention activities of a sample from the Los Angeles House and Ball communities (N=263) in order to inform future service development. While 80% of participants were tested for HIV within the past 6 months, only 26% report HIV prevention program attendance. House leaders recommend a holistic approach to HIV prevention, one that incorporates attention to social problems beyond HIV, including poverty, housing difficulties, and lack of job training.

The aim of the study was to review the Occupational Safety and Health Administration's (OSHA) 2012 to 2013 heat enforcement cases, using identified essential elements of heat illness prevention to evaluate employers' programs and make recommendations to better protect workers from heat illness. (1) Identify essential elements of heat illness prevention; (2) develop data collection tool; and (3) analyze OSHA 2012 to 2013 heat enforcement cases. OSHA's database contains 84 heat enforcement cases in 2012 to 2013. Employer heat illness prevention programs were lacking in essential elements such as providing water and shade; adjusting the work/rest proportion to allow for workload and effective temperature; and acclimatizing and training workers. In this set of investigations, most employers failed to implement common elements of illness prevention programs. Over 80% clearly did not rely on national standard approaches to heat illness prevention.

Patterson, Michael; Grant, Ashley; Paessler, Slobodan

2014-01-01

The etiologic agent of Bolivian hemorrhagic fever (BHF), Machupo virus (MACV) is reported to have a mortality rate of 25 to 35%. First identified in 1959, BHF was the cause of a localized outbreak in San Joaquin until rodent population controls were implemented in 1964. The rodent Calomys collosus was identified as the primary vector and reservoir for the virus. Multiple animal models were considered during the 1970’s with the most human-like disease identified in Rhesus macaques but minimal characterization of the pathogenesis has been published since. A reemergence of reported BHF cases has been reported in recent years, which necessitates the further study and development of a vaccine to prevent future outbreaks. PMID:24636947

Simutator operators face a twofold entity management problem during Live-Virtual-Constructive (LVC) training events. They first must filter potentially hundreds of thousands of simulation entities in order 10 determine which elements are necessary for optimal trainee comprehension. Secondarily, they must manage the number of entities entering the simulation from those present in the object model in order to limit the computational burden on the simulation system and prevent unnecessary entities from entering the simulation, This paper focuses on the first filtering stage and describes a novel approach to entity filtering undertaken to maximize trainee awareness and learning. The feasibility of this novel approach is demonstrated on a case study and limitations to the proposed approach and future work are discussed.

A Novel Therapy for People Who Attempt Suicide and Why We Need New Models of Suicide

Michel, Konrad; Valach, Ladislav; Gysin-Maillart, Anja

2017-01-01

This paper presents a model of suicidal behaviour based on suicide as a goal-directed action, and its implications. An action theoretical model has guided the authors in the development of a brief therapy for individuals who attempt suicide (ASSIP—Attempted Suicide Short Intervention Program). Key elements are an early therapeutic alliance, narrative interviewing, psychoeducation, a joint case conceptualization, safety planning, and regular letters over 24 months. In a randomized controlled trial, ASSIP was highly effective in reducing the risk of suicide reattempts. The therapeutic elements in this treatment are described and possible implications for future directions in clinical suicide prevention discussed. PMID:28257071

Between 1 August and 6 September 2013, an outbreak of Legionnaires' disease (LD) with 159 suspected cases occurred in Warstein, North Rhine-Westphalia, Germany. The outbreak consisted of 78 laboratory-confirmed cases of LD, including one fatality, with a case fatality rate of 1%. Legionella pneumophila, serogroup 1, subtype Knoxville, sequence type 345, was identified as the epidemic strain. A case-control study was conducted to identify possible sources of infection. In univariable analysis, cases were almost five times more likely to smoke than controls (odds ratio (OR): 4.81; 95% confidence interval (CI): 2.33-9.93; p < 0.0001). Furthermore, cases were twice as likely to live within a 3 km distance from one identified infection source as controls (OR: 2.14; 95% CI: 1.09-4.20; p < 0.027). This is the largest outbreak of LD in Germany to date. Due to a series of uncommon events, this outbreak was most likely caused by multiple sources involving industrial cooling towers. Quick epidemiological assessment, source tracing and shutting down of potential sources as well as rapid laboratory testing and early treatment are necessary to reduce morbidity and mortality. Maintenance of cooling towers must be carried out according to specification to prevent similar LD outbreaks in the future.

Though measles is a vaccine preventable disease, outbreaks still continue to occur because of poor immunization coverage rate at the national level. To report the survey results of an outbreak of measles in Puraini village of Madhepura district in Bihar, India. This cross-sectional survey was conducted among children aged 6 months to 12 years during an outbreak of measles in December 2008. WHO case definition criteria was used to define active measles cases. Demographic data, immunization status, and disease outcome among the cases was obtained by pre-structured questionnaires. Blood samples from 5 cases were sent for laboratory confirmation. A total of 52 cases and 8 deaths were reported with an attack rate of 28% and case fatality rate of 15.4%. Out of 35% cases of post-measles complications, dysentery with pneumonia was the most common. Anti-measles IgM antibody tested positive in all the 5 serum samples sent for confirmation. No child had received measles vaccination in the past, and the reasons were lack of awareness, lack of faith on vaccination, and unavailability of health workers. This survey calls for strengthening of disease surveillance and routine immunization coverage to achieve measles control in these communities. This has important public health implication for the whole country regarding measles elimination in near-future.

Cervical artificial disc extrusion after a paragliding accident.

2017-01-01

Cervical total disc replacement (TDR) is an established alternative to anterior cervical discectomy and fusion (ACDF) with excellent long-term outcomes and low failure rates. Cases of implant failure and migration are scarce and primarily limited to several years postoperatively. The authors report a case of anterior extrusion of a C4-C5 ProDisc-C (DePuy Synthes, West Chester, PA, USA) cervical artificial disc (CAD) 14 months after placement due to minor trauma. A 33-year-old female who had undergone C4-C5 CAD implantation presented with neck pain and spasm after experiencing a paragliding accident. A 4 mm anterior protrusion of the CAD was seen on x-ray. She underwent removal of the CAD followed by anterior fusion. Other cases of CAD extrusion in the literature are discussed and the device's durability and testing are considered. Overall, CAD extrusion is a rare event. This case is likely the result of insufficient osseous integration. Patients undergoing cervical TDR should avoid high-risk activities to prevent trauma that could compromise the disc's placement, and future design/research should focus on how to enhance osseous integration at the interface while minimizing excessive heterotopic ossification.

Elevated hip fracture incidence is a major public health problem looming to aggravate in industrialized countries due to demographic developments. We report hip fracture incidence and expected future cases from Vorarlberg, the westernmost province of Austria, results potentially representative of Central European populations. Crude and standardized hip fracture incidence rates in Vorarlberg 2003-2013 are reported. Based on the age-specific incidence in 2013 or trends 2003-2013, we predict hip fractures till 2050. Female age-standardized hip fracture incidence decreased 2005-2013, whereas for men, the trend was rather unclear. Uncorrected forecasts indicate that by 2050, female and male cases will each have more than doubled from 2015 in all demographic core scenarios. Corrected by incidence trends before 2013, cases are expected to drop among women but rise among men. We anticipate rising hip fracture numbers in Vorarlberg within the next decades, unless prevention programs that presumably account for decreasing incidence rates, particularly among women since 2005, take further effect to counteract the predicted steady increase due to demographic changes. Concomitantly, augmented endeavors to target the male population by these programs are needed.

First case of symmetric drug-related intertriginous and flexural exanthema (sdrife) due to rivastigmine?

The term 'baboon syndrome' was introduced in 1984 to describe a special form of systemic, contact-type dermatitis that occurs after ingestion or systemic absorption of a contact allergen in individuals previously sensitized by topical exposure to the same allergen in the same areas. Its clinical picture presents as an erythema of the buttocks and upper inner thighs resembling the red bottom of baboons. This reaction was originally observed with mercury, nickel, and ampicillin. In 2004, some authors proposed the acronym SDRIFE standing for 'symmetric drug-related intertriginous and flexural exanthema' specifically for cases elicited by systemically administered drugs. Since 1984, about 100 cases have been reported in the literature; for most of the concerned drugs, previous skin sensitization or possible cross-sensitization has not been shown. We report the first case of SDRIFE due to rivastigmine, with the exception of an erythematous maculopapular eruption due to rivastigmine that was previously reported. Rivastigmine is a reversible and noncompetitive acetylcholinesterase inhibitor used for the treatment of Alzheimer disease. SDRIFE is an important condition to keep in mind in order to avoid a misdiagnosis when dealing with other exanthematous disorders and to prevent re-exposure to the responsible allergen in the future.

Following the notification of nine hepatitis A cases clustered in the Cotes d Armor district in northwestern France, epidemiological, environmental and microbiological investigations were set up in order to identify the source and vehicle of contamination and implement control measures. In total, 111 cases were identified in the outbreak, all of whom lived or had stayed as tourists in the Cotes d Armor district. Of the cases, 87% had eaten raw shellfish, and 81% specifically oysters. Traceback investigations carried out on raw shellfish consumed by the cases showed that the raw shellfish originated from a single shellfish farm. The shellfish were probably contaminated either in the submersible tanks or in a depuration land-based tank where they were stored. The source of contamination was not identified but shellfish could have been tainted by sewage overflows or by wastewater releases from a polluted storm sewer close to the shellfish farm or from on-site sanitation facilities. To prevent future hepatitis A outbreaks due to shellfish consumption from this area, hazards specific to each farm should be analysed. Timely information on sewage overflows should also be part of communities efforts regarding sewage collection and treatment.

RUGs and "Medi-Cal" systems for classifying nursing home patients.

PubMed

Grimaldi, P L

1985-12-01

Medicare and most state Medicaid programs currently use indirect case-mix measures to determine reimbursement for nursing home care. In the future, however, they probably will incorporate more direct case-mix measures into their payment systems. Care must be exercised in designing a case-based prospective payment system to ensure that its financial incentives motivate providers to expedite recovery, prevent deterioration, and admit heavy-care patients. For example, although use of a services-rendered approach helps guarantee that care will be provided when needed, it also offers providers an incentive to furnish a service regardless of whether it is in the patient's best interest. Consideration must be given to the frequency with which patients are reassessed. The implications of the timing of reassessments for quality of care also must be studied. Ideally, quality would be measured on an outcome basis--that is, payment would depend on whether targeted goals for individual patients are reached--rather than on structural or process measures alone. Two recent classification systems--Resource Utilization Groups and Medi-Cal groups--may serve as models for case-based prospective payment systems. Each method classifies patients into distinct, meaningful categories based on activities of daily living and services received.

Epidemiology of gynecologic cancers in China

PubMed Central

2018-01-01

Cancer has become a major disease burden across the globe. It was estimated that 4.29 million new incident cases and 2.81 million death cases of cancer would occur in 2015 in China, with the age-standardized incidence rate (ASIR) of 201.1 per 100,000 and age-standardized mortality rate (ASMR) of 126.9 per 100,000, respectively. For females, 2 of the top 10 most common types of cancer would be gynecologic cancers, with breast cancer being the most prevalent (268.6 thousand new incident cases) and cervical cancer being the 7th most common cancer (98.9 thousand new incident cases). The incidence and mortality of gynecologic cancers have been constantly increasing in China over last 2 decades, which become a major health concern for women. Survival rates of gynecologic cancers are generally not satisfactory and decrease along with advancing stage, though national data on survival are still not available. It is of great importance to overview on the epidemiology of gynecologic cancers, which may provide scientific clues for strategy-making of prevention and control, and eventually lowering the incidence and mortality rate as well as improving the survival rate in the future.

2014-01-01

To systematically review prevalence studies of vegetative state (VS) and minimally conscious state (MCS) in geographically defined populations, to appraise study methods and assess sources of heterogeneity. MEDLINE, EBM Reviews, and EMBASE databases were searched using key terms. Two reviewers independently identified pertinent articles and screened the references for additional studies. Studies measuring the prevalence of VS and/or MCS in a defined population were included, and information on characteristics, methods, and results was extracted. Heterogeneity was quantified through the statistic I. We identified 5 cross-sectional prevalence surveys of VS and 1 of MCS. Prevalence ranged from 0.2 cases per 100,000 inhabitants to 3.4 for VS and was 1.5 per 100,000 for MCS. Relevant heterogeneity (I = 99.0%) prevented us from calculating a summary estimate. The prevalence of trauma cases varied from 21.9% to 53.8%. Variability pertaining to diagnostic criteria, definition of case, and methods of ascertainment was found. In the few prevalence studies of VS and MCS that were identified, the estimates showed high variability and could not be pooled. Future studies should consider using comparable methods for the definition, ascertainment, and confirmation of cases.

The Health Economic Impact of Universal Infant Vaccination with the 10-Valent Pneumococcal Nontypeable Haemophilus influenzae Protein D Conjugate Vaccine as Compared with 13-Valent Pneumococcal Conjugate Vaccine in Hong Kong.

Pneumococcal universal vaccination in Hong Kong was introduced in 2009. We assessed the health and economic impact of the 10-valent pneumococcal nontypeable Haemophilus influenzae protein D conjugate vaccine (PCV-10) compared with the current 13-valent pneumococcal conjugate vaccine (PCV-13) recommended for Hong Kong in 2011, providing new elements to be considered by public health authorities in the future decision-making process for pneumococcal vaccines in this country. An analytical model was used to estimate the annual economic and health outcomes of invasive pneumococcal disease (IPD), community-acquired pneumonia, and acute otitis media (AOM), including nontypeable H. influenzae-related AOM, for a birth cohort in Hong Kong from the payer perspective with a 10-year horizon. Clinical impact including morbidity-mortality, quality-adjusted life-years (QALYs), incremental costs, and cost-effectiveness comparing PCV-10 and PCV-13 were estimated. Probabilistic sensitivity analyses by using alternate scenarios were performed. Model projections indicate that PCV-13 and PCV-10 have approximately equivalent impact on the prevention of deaths caused by IPD and pneumonia. PCV-13 is projected to prevent 6 additional cases of IPD, whereas PCV-10 is projected to prevent 13,229 additional AOM cases and 101 additional QALYs. For the base case, PCV-10 vaccination is estimated to save 44.6 million Hong Kong dollars (34.1 million Hong Kong dollars discounted). Sensitivity analysis indicated that PCV-10 would generate more QALYs and save costs as compared with PCV-13. Universal infant vaccination with new available pneumococcal vaccines is expected to generate a significant additional impact on reducing the burden of pneumococcal diseases in Hong Kong. PCV-10 vaccination would be potentially a cost-saving strategy compared with PCV-13 vaccination, generating better cost offsets and higher QALY gains.

How to hold an ethical pox party.

PubMed

Jamrozik, Euzebiusz

2018-04-01

Pox parties are a controversial alternative to vaccination for diseases such as chickenpox. Such parties involve parents infecting non-immune children by exposing them to a contagious child. If successful, infection will usually lead to immunity, thus preventing infection later in life, which, for several vaccine-preventable diseases, is more severe than childhood infection. Some may consider pox parties more morally objectionable than opting out of vaccination through non-medical exemptions. In this paper, I argue that this is not the case. Pox parties involve immediate risk of harm for children and reduce future harms, whereas opting out of vaccination places children at long-term risk of harms that increase with time, at least for some pathogens. Regarding harm to others through onward transmission of infection, this can be easily prevented in the case of pox parties-given the relatively controlled timing of infection-by quarantining attendees after the party, whereas opting out of vaccination involves risks to others that are more difficult to control. I defend three criteria for an ethical pox party: (1) that the disease is sufficiently low risk, (2) that parents consent to their child's attendance and (3) that children exposed to infection are quarantined and isolated appropriately. I argue that, if these criteria are met, pox parties are morally preferable to non-vaccination; such parties involve less risk to non-consenting others and, for some pathogens in some cases, even involve less risk for the children who participate. Thus, policies that permit non-medical exemption to vaccination should also permit ethical pox parties. Alternatively, if pox parties are not permitted, then vaccination should be mandated for those without medical contraindication. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Sepsis is a life-threatening systemic condition that appears to be increasing in the obstetric population. Clinical detection can be difficult and may result in increased morbidity via delays in the continuum of patient care. To describe the burden of severe maternal morbidity (SMM) caused by sepsis in New Zealand and investigate the potential preventability. A multidisciplinary expert review panel was established to review cases of obstetric sepsis admitted to intensive care or high-dependency units over an 18 month span in New Zealand. Cases were then analysed for the characteristics of infection and their preventability. Fifty cases met the inclusion criteria, most commonly due to uterine, respiratory or kidney infection. Fifty per cent (25) of these cases were deemed potentially preventable, predominantly due to delays in diagnosis and treatment. A high index of suspicion, development of early recognition systems and multi-disciplinary training are recommended to decrease preventable cases of maternal sepsis. © 2018 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

The epidemiology of childhood tuberculosis in the Netherlands: still room for prevention

PubMed Central

2014-01-01

Background The occurrence of tuberculosis (TB) among children has long been neglected as a public health concern. However, any child with TB is a sentinel event indicating recent transmission. Vaccination, early case finding and treatment of those latently infected with TB can prevent cases, severe morbidity and unnecessary death. Method The objective of the study was to describe the occurrence of TB events among children in the Netherlands which may be avoided through preventive measures. For this purpose we performed a trend analysis of routine Dutch TB and LTBI (surveillance data in 1993–2012 and a descriptive analysis of children with TB and with LTBI diagnosed in 2005–2012). Results Overall childhood TB incidence has declined over the last two decades from 3.6 in 1993 to 1.9 per 100,000 children in 2012. The decline was stronger among Dutch-born children compared to foreign-born children. In 2005–2012 64% of childhood TB cases were detected through active case finding. Foreign-born children with TB were less likely to be detected through active case finding, when not detected through post-entry TB screening. Childhood TB diagnosis was culture confirmed in 68% of passively detected cases and 12% of actively detected cases. Of 1,049 children with LTBI started on preventive treatment in 2005–2012, 90% completed treatment. In 37% of all childhood TB cases there was at least one ‘missed opportunity’ for prevention. Thirty nine percent of child TB patients eligible for BCG were not vaccinated. Conclusion Children with TB in the Netherlands are generally detected at an early stage and treatment completion rates are high. However, more TB cases among children can be prevented through enhancing TB case finding and screening and preventive treatment of latent TB infection among migrant children, and improving the coverage of BCG vaccination among eligible risk groups.

Vast amounts of injury narratives are collected daily and are available electronically in real time and have great potential for use in injury surveillance and evaluation. Machine learning algorithms have been developed to assist in identifying cases and classifying mechanisms leading to injury in a much timelier manner than is possible when relying on manual coding of narratives. The aim of this paper is to describe the background, growth, value, challenges and future directions of machine learning as applied to injury surveillance. This paper reviews key aspects of machine learning using injury narratives, providing a case study to demonstrate an application to an established human-machine learning approach. The range of applications and utility of narrative text has increased greatly with advancements in computing techniques over time. Practical and feasible methods exist for semiautomatic classification of injury narratives which are accurate, efficient and meaningful. The human-machine learning approach described in the case study achieved high sensitivity and PPV and reduced the need for human coding to less than a third of cases in one large occupational injury database. The last 20 years have seen a dramatic change in the potential for technological advancements in injury surveillance. Machine learning of 'big injury narrative data' opens up many possibilities for expanded sources of data which can provide more comprehensive, ongoing and timely surveillance to inform future injury prevention policy and practice.

Asbestos is a first level carcinogen. However, few epidemiological studies analyse the risk and protective factors associated with asbestos-related diseases and follow up these conditions in the general population. Pleural mesothelioma, caused by inhalation of asbestos fibres at work, at home or in the environment, is the most representative asbestos-related disease.The objectives of this study are to analyse the risk and protective factors associated with asbestos-related diseases and to investigate the incidence of new clinical manifestations in patients already diagnosed with some form of ARD. We have designed a matched case-control study with follow up of both cohorts from a population of a health district of the Barcelona province that has been exposed to asbestos for a period of 90 years. A better understanding of asbestos-related diseases should improve i) the clinical and epidemiological follow up of patients with this condition; ii) the design of new treatment strategies; iii) and the development of preventive activities. At the end of the study, the two cohorts created in this study (affected cases and healthy controls) will constitute the basis for future research.

Financing of malaria control for displaced populations is limited in scope and duration, making cost-effectiveness analyses relevant but difficult. This study analyses cost-effectiveness of adding prevention through targeted indoor residual spraying (IRS) to case management in Afghan refugee settlements in Pakistan during a prolonged malaria epidemic. An intervention study design was selected, taking a societal perspective. Provider and household costs of vector control and case management were collected from provider records and community survey. Health outcomes (e.g. cases and DALYs averted) were derived and incremental cost-effectiveness ratios (ICERs) for cases prevented and DALYs averted calculated. Population, treatment cost, women's time, days of productivity lost, case fatality rate, cases prevented, and DALY assumptions were tested in sensitivity analysis. Malaria incidence peaked at 44/1,000 population in year 2, declining to 14/1,000 in year 5. In total, 370,000 malaria cases, 80% vivax, were diagnosed and treated and an estimated 67,988 vivax cases and 18,578 falciparum and mixed cases prevented. Mean annual programme cost per capita was US$0.56. The additional cost of including IRS over five years per case prevented was US$39; US$50 for vivax (US$43 in years 1-3, US$80 in years 4-5) and US$182 for falciparum (US$139 in years 1-3 and US$680 in years 4-5). Per DALY averted this was US$266 (US$220 in years 1-3 and US$486 in years 4-5) and thus 'highly cost-effective' or cost-effective using WHO and comparison thresholds. Adding IRS was cost-effective in this moderate endemicity, low mortality setting. It was more cost-effective when transmission was highest, becoming less so as transmission reduced. Because vivax was three times more common than falciparum and the case fatality rate was low, cost-effectiveness estimations for cases prevented appear reliable and more definitive for vivax malaria.

The future of clinical cancer genomics.

Offit, Kenneth

2016-10-01

The current and future applications of genomics to the practice of preventive oncology are being impacted by a number of challenges. These include rapid advances in genomic science and technology that allow massively parallel sequencing of both tumors and the germline, a diminishing of intellectual property restrictions on diagnostic genetic applications, rapid expansion of access to the internet which includes mobile access to both genomic data and tools to communicate and interpret genetic data in a medical context, the expansion of for-profit diagnostic companies seeking to monetize genetic information, and a simultaneous effort to depict medical professionals as barriers to rather than facilitators of understanding one's genome. Addressing each of these issues will be required to bring "personalized" germline genomics to cancer prevention and care. A profound future challenge will be whether clinical cancer genomics will be "de-medicalized" by commercial interests and their advocates, or whether the future course of this field can be modulated in a responsible way that protects the public health while implementing powerful new medical tools for cancer prevention and early detection.

Enterobius vermicularis (pinworm) infection of the liver mimicking malignancy: Presentation of a new case and review of current literature

PubMed Central

Arkoulis, Nikolaos; Zerbinis, Helen; Simatos, Georgios; Nisiotis, Athanasios

2011-01-01

INTRODUCTION Enterobius vermicularis or “pinworm” infection of the liver is an extremely rare condition with only five cases previously reported in literature. It is characterized by the presence of granulomas in the liver with a necrotic core, containing adult helminthes or their ova. Because of the relatively mild symptomatology associated with this disease, prior to the arrival of modern imaging methods hepatic enterobiasis was an incidental intra-operative finding during abdominal surgery for other conditions. In recent years however, with high-resolution abdominal imaging readily available and the improved safety of hepatic resection, a lower threshold for treating suspicious hepatic nodules aggressively with surgery is being adopted. PRESENTATION OF CASE We present the second case in international literature, where E. vermicularis of the liver was mistaken for malignancy and led to hepatic resection and perform a literature review of the five previously documented cases of hepatic enterobiasis. DISCUSSION Our report identifies certain trends in this condition's aetiology and clinical behaviour, but due to its rarity definitive answers cannot yet be established. CONCLUSION We do not advocate a change in the current approach of suspicious hepatic nodules, but we do feel that better understanding of the mechanisms involved with hepatic enterobiasis could, in the future, prevent unnecessary surgery.

Pathways Triple P and the Child Welfare System: A Promising Fit.

PubMed

Petra, Megan; Kohl, Patricia

2010-04-01

Parents referred to the child welfare system following maltreatment allegations are often ill-prepared to constructively address child disruptive behaviors, despite the high prevalence of these behaviors among this population. Evidence-based parent-mediated interventions are effective in improving parenting skills; however, they are rarely offered within the child welfare system. The purpose of this pilot project was to evaluate the fit and acceptability of one parent-mediated training program (Pathways Triple P) to case managers and parents within this system of care. We implemented Pathways Triple P and subsequently interviewed referring case managers and parents who had participated in the program. Case managers felt the program would work well within the existing child welfare system and would help them to better serve parents. They felt the program had potential to improve parenting skills and prevent future maltreatment. Parents appreciated the program's use of diverse methods, and the variety of parenting techniques taught. In keeping with case manager expectations, participants reported that their enhanced parenting skills and new ability to use non-physical discipline resulted in a better home life. We conclude that Pathways Triple P fits well within the child welfare system and is acceptable to both case managers and parents within this system.

Global trends such as digitalisation, globalisation and demographic change are changing workplaces, and accordingly occupational safety and health (OSH) needs. To better prepare for the future and to foster proactive prevention, the German Social Accident Insurance (DGUV) established an OSH risk observatory (RO OSH). The RO OSH relies on an online survey and calls upon the expertise of labour inspectors. 398 labour inspectors participated in the first RO OSH enquiry. They rated developments with regard to their sector-specific relevance for OSH in the near future. The RO OSH also provides ideas for preventive measures that can be implemented by the German Social Accident Insurance Institutions. Work intensity, demographic aspects, and digitalisation play a major role for most or all sectors. However, familiar OSH issues such as musculoskeletal strain and noise also continue to be of major importance and require further consideration and specific solutions in prevention. For the DGUV, training and consulting bear great potential for proactive prevention in the above priority areas, e.g. by fostering a prevention culture and supporting companies in (psychosocial) risk assessment (also for mobile work). For instance, concepts for increasing physical activity at sedentary workplaces, and data security require continued research.

How far can we prevent further physical soil degradation in the future?

NASA Astrophysics Data System (ADS)

Horn, Rainer

2017-04-01

Arable as well as forest soils are exposed to increasing external stresses, which coincide with a further and deeper reaching soil degradation, which may result in an aggravation of hydraulic, gaseous, thermal but also physicochemical and chemical soil functions. The decline coincides with a simultaneous reduction in useable land areas and worsens food production amongst others. Therefore, it is mandatory, that stable soil structure from the surface down to depth prevents soil compaction, sustains water infiltration, reduces rates of soil erosion by water and wind in each case to the minimum possible under the soil, terrain, land use, and climatic conditions in which the soils occur. It improves organic carbon storage in soils and optimizes microbial activity and functions. These benefits coincide with sustainable soil properties and soil management systems, which prevent - deep mechanical stress propagation which can cause irreversible soil deformation, - loss of surface soil layers with coinciding organic and mineral nutrient pool available for microbial processing and plant uptake, - Truncation of soil horizons, or damage on private and public infrastructures (roads, houses) and downstream fields. In order to prevent negative impacts on soils, it is recommended, that A) concerning prevention of soil compaction - stresses applied to soils shall not exceed the mechanical soil stability to maintain the actual functioning of chemical, physical and biological processes and to utilize their resilience (i.e. the elasticity), - land use management strategies have to be related to the actual soil properties in order to optimize plant growth, yield, filtering and buffering of infiltrating water, and carbon sequestration. B) soil erosion by - water, wind, and tillage is counteracted by an adequate surface soil stability including a site specific residue management (e.g. conservation tillage), controlled traffic and harvesting, ecological grassland use strategies (e.g. fodder production and harvesting, adequate animal grazing), - wind is furthermore minimized by adequate hedgerow plantations, continuous cover crop growth, optimized particle bindings by water, infiltrating organic acids, appropriate grazing intensity. Agroforestry can be considered as an additional positive measure to reduce soil erosion risks generally and to ameliorate degraded sites. C) -plant cover on slopes remains untouched, overgrazing and consecutive soil homogenization especially under moist climatic conditions must be prevented but adjusted to the actual structure stability of the hillsides. The communication of these findings followed by application of such measures can help farmers and foresters as well as landowners to prevent (further) physical soil degradation in the future.

Does BCG vaccine prevent tuberculous meningitis?

1996-01-01

The reported efficacy of BCG vaccine in preventing pulmonary tuberculosis varies from 0-80%; however, its efficacy in preventing tuberculous meningitis ranges from 52%-84%. A case-control study was conducted to assess the efficacy of BCG in preventing tuberculous meningitis in children. New cases of tuberculous meningitis, confirmed bacteriologically, were registered as cases. Controls were children suffering from febrile convulsions attending the same hospital. A total of 107 cases and 321 controls, block matched for age, were registered. Vaccination status was determined from the history reported by the mother and by BCG scar reading. Data regarding socioeconomic status, crowding, and nutritional status were collected. Using multiple logistic regression analysis the odds ratio obtained for the presence of BCG scar was 0.23 (95% confidence interval (CI) 0.14 to 0.37) and the protective efficacy of BCG vaccine in preventing tuberculous meningitis in children was found to be 77% (95% CI 71 to 83%).

To develop a descriptive model of preventability for maternal morbidity and mortality that can be used in quality assurance and morbidity and mortality review processes. This descriptive study was part of a larger case-control study conducted at the University of Illinois at Chicago in which maternal deaths were cases and women with severe maternal morbidity served as controls. Morbidities and mortalities were classified by a team of clinicians as preventable or not preventable. Qualitative analysis of data was conducted to identify and categorize different types of preventable events. Of 237 women, there were 79 women with preventable events attributable to provider or system factors. The most common types of preventable events were inadequate diagnosis/recognition of high-risk (54.4%), treatment (38.0%), and documentation (30.7%). A descriptive model was illustrated that can be used to categorize preventable events in maternal morbidity and mortality and can be incorporated into quality assurance and clinical case review to enhance the monitoring of hospital-based obstetric care and to decrease medical error.

The WHO surgical safety checklist (SSC) is known to prevent postoperative complications; however, strategies for effective implementation are unclear. In addition to cultural and organizational barriers faced by high-income countries, resource-constrained settings face scarcity of durable and consumable goods. We used the SSC to better understand barriers to improvement at a trauma hospital in Battambang, Cambodia. We introduced the SSC and trained data collectors to observe surgical staff performing the checklist. Members of the research team observed cases and data collection. After 3 months, we modified the data collection tool to focus on infection prevention and elicit more accurate responses. Over 16 months we recorded data on 695 operations (304 cases using the first tool and 391 cases with the modified tool). The first tool identified five items as being in high compliance, which were then excluded from further assessment. Two items-instrument sterility confirmation and sponge counting-were identified as being misinterpreted by the data collectors' tool. These items were reworded to capture objective assessment of task completion. Confirmation of instrument sterility was initially never performed but rectified to >95% compliance; sponge counting and prophylactic antibiotic administration were consistently underperformed. Staff complied with communication elements of the SSC and quickly adopted process improvements. The wording of our data collection tool affected interpretation of compliance with standards. Material resources are not the primary barrier to checklist implementation in this setting, and future work should focus on clarification of protocols and objective confirmation of tasks.

2015-01-01

Background. Five years since the successful introduction of MenAfriVac in a mass vaccination campaign targeting 1- to 29-year-olds in Burkina Faso, consideration must be given to the optimal strategies for sustaining population protection. This study aims to estimate the economic impact of a range of vaccination strategies in Burkina Faso. Methods. We performed a cost-of-illness study, comparing different vaccination scenarios in terms of costs to both households and health systems over a 26-year time horizon. These scenarios are (1) reactive vaccination campaign (baseline comparator); (2) preventive vaccination campaign; (3) routine immunization at 9 months; and (4) a combination of routine and an initial catchup campaign of children under 5. Costs were estimated from a literature review, which included unpublished programmatic documents and peer-reviewed publications. The future disease burden for each vaccination strategy was predicted using a dynamic transmission model of group A Neisseria meningitidis. Results. From 2010 to 2014, the total costs associated with the preventive campaign targeting 1- to 29-year-olds with MenAfriVac were similar to the estimated costs of the reactive vaccination strategy (approximately 10 million US dollars [USD]). Between 2015 and 2035, routine immunization with or without a catch-up campaign of 1- to 4-year-olds is cost saving compared with the reactive strategy, both with and without discounting costs and cases. Most of the savings are accrued from lower costs of case management and household costs resulting from a lower burden of disease. After the initial investment in the preventive strategy, 1 USD invested in the routine strategy saves an additional 1.3 USD compared to the reactive strategy. Conclusions. Prevention strategies using MenAfriVac will be significantly cost saving in Burkina Faso, both for the health system and for households, compared with the reactive strategy. This will protect households from catastrophic expenditures and increase the development capacity of the population. PMID:26553677

Answer questions and earn CME/CNE Screening to detect polyps or cancer at an early stage has been shown to produce better outcomes in colorectal cancer (CRC). Programs with a population-based approach can reach a large majority of the eligible population and can offer cost-effective interventions with the potential benefit of maximizing early cancer detection and prevention using a complete follow-up plan. The purpose of this review was to summarize the key features of population-based programs to increase CRC screening in the United States. A search was conducted in the SCOPUS, OvidSP, and PubMed databases. The authors selected published reports of population-based programs that met at least 5 of the 6 International Agency for Research on Cancer (IARC) criteria for cancer prevention and were known to the National Colorectal Cancer Roundtable. Interventions at the level of individual practices were not included in this review. IARC cancer prevention criteria served as a framework to assess the effective processes and elements of a population-based program. Eight programs were included in this review. Half of the programs met all IARC criteria, and all programs led to improvements in screening rates. The rate of colonoscopy after a positive stool test was heterogeneous among programs. Different population-based strategies were used to promote these screening programs, including system-based, provider-based, patient-based, and media-based strategies. Treatment of identified cancer cases was not included explicitly in 4 programs but was offered through routine medical care. Evidence-based methods for promoting CRC screening at a population level can guide the development of future approaches in health care prevention. The key elements of a successful population-based approach include adherence to the 6 IARC criteria and 4 additional elements (an identified external funding source, a structured policy for positive fecal occult blood test results and confirmed cancer cases, outreach activities for recruitment and patient education, and an established rescreening process). © 2015 American Cancer Society.

Rationale: Addiction prevention is a major public health problem, particularly concerning young people. Despite the consensus that primary prevention is essential, the evaluation of its impact is questioned. Objective: The objective of this paper is to assess the latest knowledge of addiction prevention programs for young people. Method: Review a collection of research articles using a keyword-based search on three databases: Pubmed, Eric, and PsycInfo. The research was carried out using three groups of keywords and the eligibility study was completed using two criteria: articles published between 2010 and 2017, and articles in refereed journals. Results: Of a total of 13,720 articles in the three databases, 32 studies were included in the review and listed in a grid with five themes: authors, type of population, total population, addictive behavior, and results. Four categories were created based on the objective of the studies: the evaluation of prevention strategies, the study of risk factors for consumption, the prevalence study and other subjects studied. The analysis of the corpus was used to establish a list of risk factors to be taken into consideration in future interventions and research. A list of key elements for performing effective interventions and future research is also proposed. Conclusion: The understanding of the prevention strategies implementation process is discussed as a central element for future research, which will combine stakeholders and researchers. The complexity of the situations and the multifactorial aspects of addiction prevention in young people require a multidisciplinary approach involving the various stakeholders and researchers.

Acute respiratory syndrome after inhalation of waterproofing sprays: a posteriori exposure-response assessment in 102 cases.

Waterproofing agents are widely used to protect leather and textiles in both domestic and occupational activities. An outbreak of acute respiratory syndrome following exposure to waterproofing sprays occurred during the winter 2002-2003 in Switzerland. About 180 cases were reported by the Swiss Toxicological Information Centre between October 2002 and March 2003, whereas fewer than 10 cases per year had been recorded previously. The reported cases involved three brands of sprays containing a common waterproofing mixture, that had undergone a formulation change in the months preceding the outbreak. A retrospective analysis was undertaken in collaboration with the Swiss Toxicological Information Centre and the Swiss Registries for Interstitial and Orphan Lung Diseases to clarify the circumstances and possible causes of the observed health effects. Individual exposure data were generated with questionnaires and experimental emission measurements. The collected data was used to conduct numeric simulation for 102 cases of exposure. A classical two-zone model was used to assess the aerosol dispersion in the near- and far-field during spraying. The resulting assessed dose and exposure levels obtained were spread on large scales, of several orders of magnitude. No dose-response relationship was found between exposure indicators and health effects indicators (perceived severity and clinical indicators). Weak relationships were found between unspecific inflammatory response indicators (leukocytes, C-reactive protein) and the maximal exposure concentration. The results obtained disclose a high interindividual response variability and suggest that some indirect mechanism(s) predominates in the respiratory disease occurrence. Furthermore, no threshold could be found to define a safe level of exposure. These findings suggest that the improvement of environmental exposure conditions during spraying alone does not constitute a sufficient measure to prevent future outbreaks of waterproofing spray toxicity. More efficient preventive measures are needed prior to the marketing and distribution of new waterproofing agents.

The ongoing development of novel nicotine vaccines makes it urgent to identify the normative questions around this innovative health technology against smoking. A qualitative thematic analysis of peer-reviewed papers on nicotine vaccination published between 2001 and 2013. In the scientific discourse, nicotine vaccination is presented in a neurobiological frame as a potent concept for (long-term) smoking cessation. Nicotine vaccination is also considered a hypothetical strategy to prevent nicotine addiction in minors. Ethical assessments are conducted for the use of nicotine vaccination in public health and clinical medicine. Whereas vaccination for primary prevention is usually associated with public health, the hypothetical case of nicotine prevention in minors is also assessed for individualized protection. Therapeutic and preventive applications are given uneven attention: the classic goal of vaccination (primary prevention in minors) receives methodical consideration and invokes lively debate. The unprecedented use of vaccination, namely smoking cessation, is left largely unattended in the ethical analyses. While health innovations such as nicotine vaccination need broad reflection to guide decisions on their further development and possible future implementations, only a small part of the ethical and social issues of this innovative technology has been discussed. For a debate to come into existence, a 'neurobio-psycho-socio-cultural' frame of smoking and quitting appears fruitful. Important topics for reflection are the human activities and social processes in a vaccine-supported quit attempt, next to respect for individuals, possible harms and questions of (global) justice and research ethics. © 2014 Society for the Study of Addiction.

2010-01-01

Objective Prevention of late-life depression, a common, disabling condition with often poor outcomes in primary care, requires identification of seniors at highest risk of incident episodes. The authors examined a broad range of clinical, functional, and psychosocial predictors of incident depressive episodes in a well-characterized cohort of older primary care patients. Method In this observational cohort study, patients age ≥65 years without current major depression, recruited from practices in general internal medicine, geriatrics, and family medicine, received annual follow-up assessments over a period of 1 to 4 years. Of 617 enrolled subjects, 405 completed the 1-year follow-up evaluation. The Structured Clinical Interview for DSM-IV (SCID) determined incident major depressive episodes. Each risk indicator’s predictive utility was examined by calculating the risk exposure rate, incident risk ratio, and population attributable fraction, leading to determination of the number needed to treat in order to prevent incident depression. Results A combination of risks, including minor or subsyndromal depression, impaired functional status, and history of major or minor depression, identified a group in which fully effective treatment of five individuals would prevent one new case of incident depression. Conclusions Indicators routinely assessed in primary care identified a group at very high risk for onset of major depressive episodes. Such markers may inform current clinical care by fostering the early detection and intervention critical to improving patient outcomes and may serve as the basis for future studies refining the recommendations for screening and determining the effectiveness of preventive interventions.

Neuromyelitis Optica Spectrum Disorder (NMOSD) is a relapsing neuro inflammatory disease of the central nervous system that typically presents with optic neuritis or myelitis and may cause severe disability. The diagnostic criteria have been updated and several immunosuppressive agents have been demonstrated to prevent acute exacerbations. As the disease rarely develops in a progressive course, management of acute attacks and proper prevention of exacerbations may change the long term out-come and prevent future disability. Consensus recommendations and guidelines will help the physicians to improve their practice and unify the treatment approaches in different communities. In order to develop a national consensus and recommendations for the diagnosis and management of NMOSD in Iran, a group of neurologists with long term experience in management of NMOSD were gathered to develop this consensus based on available national and international data. The primary draft was prepared and discussed to suggest the most appropriate treatment for these patients. We propose strategies for early diagnosis and treatment for prevention of relapses and minimizing consequences of attacks as a primary therapeutic goal. Attacks are currently treated with intravenous corticosteroids and, in refractory cases, with plasma exchange. All participants agreed on preventive treatment with currently available immunosuppressive agents such as azothioprin, rituximab and mycofenolate mofetil based on previous positive data in NMOSD in order to reduce attack frequency. The current consensus reviews the previous data and provides the clinicians with practical recommendations and advices for the diagnosis and management of NMOSD based on scientific data and clinical experience.

Understanding Arsenic Dynamics in Agronomic Systems to ...

EPA Pesticide Factsheets

This review is on arsenic in agronomic systems, and covers processes that influence the entry of arsenic into the human food supply. The scope is from sources of arsenic (natural and anthropogenic) in soils, biogeochemical and rhizosphere processes that control arsenic speciation and availability, through to mechanisms of uptake by crop plants and potential mitigation strategies. This review makes a case for taking steps to prevent or limit crop uptake of arsenic, wherever possible, and to work toward a long-term solution to the presence of arsenic in agronomic systems. The past two decades have seen important advances in our understanding of how biogeochemical and physiological processes influence human exposure to soil arsenic, and thus must now prompt an informed reconsideration and unification of regulations to protect the quality of agricultural and residential soils. Consumption of staple foods such as rice, beverages such as apple juice, or vegetables grown in historically arsenic-contaminated soils is now recognized as a tangible route of arsenic exposure that, in many cases, is more significant than exposure from drinking water. Understanding the sources of arsenic to crop plants and the factors that influence them is key to reducing exposure now and preventing exposure in future. In addition to the abundant natural sources of arsenic, there are a large number of industrial and agricultural sources of arsenic to the soil; from mining wastes, coal fly

The US President's Emergency Plan for AIDS Relief (PEPFAR) has supported a comprehensive package of care in which interventions to address HIV-related tuberculosis (TB) have received increased funding and support in recent years. PEPFAR's TB/HIV programming is based on the World Health Organization's 12-point policy for collaborative TB/HIV activities, which are integrated into PEPFAR annual guidance. PEPFAR implementing partners have provided crucial support to TB/HIV collaboration, and as a result, PEPFAR-supported countries in sub-Saharan Africa have made significant gains in HIV testing and counseling of TB patients and linkages to HIV care and treatment, intensified TB case finding, and TB infection control. PEPFAR's support of TB/HIV integration has also included significant investment in health systems, including improved laboratory services and educating and enlarging the workforce. The scale-up of antiretroviral therapy along with support of programs to increase HIV counseling and testing and improve linkage and retention in HIV care may have considerable impact on TB morbidity and mortality, if used synergistically with isoniazid preventive therapy, intensified case finding, and infection control. Issues to be addressed by future programming include accelerating implementation of isoniazid preventive therapy, increasing access and ensuring appropriate use of new TB diagnostics, supporting early initiation of antiretroviral therapy for HIV-infected TB patients, and strengthening systems to monitor and evaluate program implementation.

Wants Talk Psychotherapy but Cannot Talk

While post-stroke depression (PSD) is a common sequelae of stroke, many stroke survivors also have expressive aphasia (i.e., the inability to produce spoken or written language), which limits or prevents treating depression with talk psychotherapy. Unlike most psychotherapy modalities, eye movement desensitization and reprocessing (EMDR) does not require extensive verbal communication to therapists, which might make EMDR an ideal treatment modality for aphasic patients with mental health concerns. The authors present the first known case reporting EMDR in aphasia, describing the treatment of a 50-year-old woman with a history of depression following a left middle cerebral artery stroke. Left frontal lobe strokes are independently associated with both PSD and expressive aphasia. EMDR began two years following the stroke, at which point the patient continued to have persistent expressive aphasia despite previously completing more than a year of speech therapy. Using the Blind to Therapist Protocol, EMDR successfully led to improvement in depressive symptoms and, surprisingly, improvement in aphasia. This case report suggests that EMDR might be beneficial for those with mental health concerns who have expressive communication impairments that might prevent treatment with other psychotherapy modalities. We discuss potential challenges and technical workarounds with EMDR in aphasia, we speculate about potential biopsychosocial explanations for our results, and we recommend future research on EMDR for PSD and other mental health concerns in the context of aphasia, as well as possibly for aphasia itself.

The Ebola virus disease spread rapidly in West Africa in 2014, leading to the loss of thousands of lives. Community engagement was one of the key strategies to interrupt Ebola transmission, and practical community level measures needed to be explored in the field and tailored to the specific context of communities. First, community-level education on Ebola virus disease (EVD) prevention was launched for the community's social mobilizers in six districts in Sierra Leone beginning in November 2014. Then, from January to May of 2015, in three pilot communities, local trained community members were organized to engage in implementation of EVD prevention and transmission interruption measures, by involving them in alert case report, contact tracing, and social mobilization. The epidemiological indicators of transmission interruption in three study communities were evaluated. A total of 6 016 community social mobilizers from 185 wards were trained by holding 279 workshops in the six districts, and EVD message reached an estimated 631 680 residents. In three pilot communities, 72 EVD alert cases were reported, with 70.8 % of them detected by trained local community members, and 14 EVD cases were finally identified. Contact tracing detected 64.3 % of EVD cases. The median duration of community infectivity for the cases was 1 day. The secondary attack rate was 4.2 %, and no third generation of infection was triggered. No health worker was infected, and no unsafe burial and noncompliance to EVD control measures were recorded. The community-based measures were modeled to reduce 77 EVD cases, and the EVD-free goal was achieved four months earlier in study communities than whole country of Sierra Leone. The community-based strategy of social mobilization and community engagement was effective in case detection and reducing the extent of Ebola transmission in a country with weak health system. The successfully practical experience to reduce the risk of Ebola transmission in the community with poor resources would potentially be helpful for the global community to fight against the EVD and the other diseases in the future.

Background Neonatal herpes is a rare but potentially devastating condition (60% fatality without treatment). Transmission usually occurs during delivery from mothers with herpes simplex virus type 1 (HSV-1) or HSV-2 genital infection. The global burden has never been quantified. We developed a novel methodology for burden estimation and present first WHO global and regional estimates of the annual number of neonatal herpes cases during 2010–2015. Methods Previous estimates of HSV-1 and HSV-2 prevalence and incidence in women aged 15–49 years were applied to 2010–2015 birth rates to estimate infections during pregnancy. Published risks of neonatal HSV transmission were then applied according to whether maternal infection was incident or prevalent with HSV-1 or HSV-2 to estimate neonatal herpes cases. Findings Globally the overall rate of neonatal herpes was estimated to be ~10 cases per 100,000 births, equivalent to a best-estimate of ~14,000 cases annually (HSV-1: ~4,000; HSV-2: ~10,000). We estimated that the most neonatal herpes cases occurred in Africa, due to high maternal HSV-2 infection and high birth rates. HSV-1 contributed more cases than HSV-2 in the Americas, Europe and Western Pacific. High rates of genital HSV-1 infection and moderate HSV-2 prevalence meant the Americas had the highest overall rate. However, our estimates are highly sensitive to the core assumptions, and considerable uncertainty exists for many settings given sparse underlying data. Interpretation These neonatal herpes estimates mark the first attempt to quantify the global burden of this rare but serious condition. Better primary data collection on neonatal herpes is critically needed to reduce uncertainty and refine future estimates. This is particularly important in resource-poor settings where we may have underestimated cases. Nevertheless, these first estimates suggest development of new HSV prevention measures such as vaccines could have additional benefits beyond reducing genital ulcer disease and HSV-associated HIV transmission, through prevention of neonatal herpes.

Sporadic Creutzfeldt-Jakob disease (sCJD) is potentially transmissible to humans. This study aimed to summarise and rate the quality of the evidence of the association between surgery and sCJD. Firstly, we conducted systematic reviews and meta-analyses of case-control studies with major surgical procedures as exposures under study. To assess quality of evidence, we used the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. Secondly, we conducted a systematic review of sCJD case reports after sharing neurosurgical instruments. Thirteen case-control studies met the inclusion criteria for the systematic review of case-control studies. sCJD was positively associated with heart surgery, heart and vascular surgery and eye surgery, negatively associated with tonsillectomy and appendectomy, and not associated with neurosurgery or unspecified major surgery. The overall quality of evidence was rated as very low. A single case-control study with a low risk of bias found a strong association between surgery conducted more than 20 years before disease onset and sCJD. Seven cases were described as potentially transmitted by reused neurosurgical instruments. The association between surgery and sCJD remains uncertain. Measures currently recommended for preventing sCJD transmission should be strongly maintained. Future studies should focus on the potential association between sCJD and surgery undergone a long time previously.

To reach the tuberculosis (TB) elimination goals established by the Institute of Medicine (IOM) and the Centers for Disease Control and Prevention (CDC), measures must be taken to speed the currently stagnant TB elimination rate and curtail a future peak in TB incidence. Increases in TB incidence have historically coincided with immigration, poverty, and joblessness; all situations that are currently occurring worldwide. Effective TB elimination strategies will require the geographical elucidation of areas within the U.S. that have endemic TB, and systematic surveillance of the locations and location-based risk factors associated with TB transmission. Surveillance data was used to assess the spatial distribution of cases, the yearly TB incidence by census tract, and the statistical significance of case clustering. The analysis revealed that there are neighborhoods within Houston/Harris County that had a heavy TB burden. The maximum yearly incidence varied from 245/100,000-754/100,000 and was not exclusively dependent of the number of cases reported. Geographically weighted regression identified risk factors associated with the spatial distribution of cases such as: poverty, age, Black race, and foreign birth. Public transportation was also associated with the spatial distribution of cases and census tracts identified as high incidence were found to be irregularly clustered within communities of varied SES.

A neutrophil-predominant inflammatory infiltrate in a cutaneous biopsy can be associated with a broad spectrum of diseases. Here we describe three cases showing a neutrophil-predominant dermal infiltrate admixed with abundant acellular bodies surrounded by capsule-like vacuolated spaces, which strikingly mimicked Cryptococcus. Two cases occurred within the settings of underlying hematologic malignancies; the third case was associated with immune dysregulation. Two patients were acutely ill in the medical intensive care unit. Fungal work-up, including cultures and multiple stains were negative. Because of clinical deterioration in these patients, transmission electron microscopy was pursued to definitively rule out fungal infection. In both cases, characteristics most compatible with autolysing human cells, not Cryptococcus, were identified. Chemotherapy and high-dose steroids were given, but both patients eventually succumbed to their diseases. To the best of our knowledge, these represent the first reported cases of autolysing human cells mimicking Cryptococcus organisms within neutrophilic infiltrates. They highlight the therapeutic dilemmas arising with histopathologic mimics, as well as the importance of thorough investigation to distinguish mimickers from true infectious organisms. We believe recognition of this microscopic pitfall will be useful to dermatopathologists faced with similar findings in the future, and may prevent unnecessary delay of appropriate therapy in acutely ill patients.

Venous thromboembolism (VTE) is an important cause of in-hospital mortality. A local understanding of disease burden, occurrence, etiology and successful preventive and therapeutic interventions is of vital import. We aimed to review the current literature of VTE originating from Pakistan to determine gaps in knowledge in order to prioritize future research. An electronic search was performed using Pakmedinet, Pubmed and Google Scholar to retrieve research articles on thrombosis, deep vein thrombosis and pulmonary thromboembolism in Pakistan. The search included all years and no limits were applied. All original research articles presenting primary data from Pakistan were selected. Full texts were reviewed and information synthesized and summarized in our review. Eighty-one studies were found, out of which we were able to retrieve and review 77 (95%) full texts. A total of 6,501 patients are included in this review. Among the studies, we found 25 case reports/series, 1 case-control, 3 cohort, 20 cross-sectional, 1 quasi-experimental, 2 randomized controlled trials, 4 retrospective file reviews and 21 review articles. Most of these were small studies with only eight having a patient population above 100. Six studies presented incidence of DVT which ranged from 2.6 to 12.82% depending on the population under study. Two articles studied risk factors for DVT. Six looked at different treatment modalities, often comparing one modality to the other, while another 15 articles assessed diagnostic strategies. Preventive aspects of VTE were addressed by only three studies and all found the rates of thrombo-prophylaxis grossly inadequate. There is a dearth of quality research on venous thromboembolism in Pakistan. We describe key areas of neglect and recommend prioritizing research on epidemiological and preventive aspects.

Since an important goal of the youth welfare system is to prevent troubled adolescents from committing acts of delinquency in future, professional caregivers need to possess accurate knowledge about past behaviors in order to implement appropriate interventions. As part of a comprehensive study on youth in state care, adolescents at 30 residential care facilities in Switzerland were surveyed about past acts of delinquency, and their responses were compared to those of their professional caregivers to see how well they correlated. A sample of 267 male and female adolescents aged 11-18years completed questionnaires about the frequency, nature, and seriousness of different types of offenses, while a designated caregiver for each resident completed a corresponding questionnaire. The majority of residents (86.1%) reported having committed at least one offense, which confirms the prevalence of problem behaviors in this population and the need for strategies to prevent it. The overall rate of agreement between the residents and their caregivers was 77.2%, with both parties reporting that the resident had committed at least one offense in 69.7% of cases, and both reporting that no offense had been committed in 7.5% of cases. Agreement was substantially higher for offenses that were serious than for those that were minor or moderate. Cohen's kappa reached slight to moderate values with regard to individual and categorized offenses. Seriousness scales of delinquency for self-reports and caregiver reports were moderately associated. While the overall rate of agreement between the residents and their caregivers was high, increasing it still further might lead to improvements in strategies for the prevention of recidivism.

Ståhl, Christian; Costa-Black, Katia; Loisel, Patrick

2018-04-01

This article explores and applies theories for analyzing socio-political aspects of implementation of work disability prevention (WDP) strategies. For the analysis, theories from political science are explained and discussed in relation to case examples from three jurisdictions (Sweden, Brazil and Québec). Implementation of WDP strategies may be studied through a conceptual framework that targets: (1) the institutional system in which policy-makers and other stakeholders reside; (2) the ambiguity and conflicts regarding what to do and how to do it; (3) the bounded rationality, path dependency and social systems of different stakeholders; and (4) coalitions formed by different stakeholders and power relations between them. In the case examples, the design of social insurance systems, the access to and infrastructure of healthcare systems, labor market policies, employers' level of responsibility, the regulatory environment, and the general knowledge of WDP issues among stakeholders played different roles in the implementation of policies based on scientific evidence. Future research may involve participatory approaches focusing on building coalitions and communities of practice with policy-makers and stakeholders, in order to build trust, facilitate cooperation, and to better promote evidence utilization. Implications for Rehabilitation Implementation of work disability prevention policies are subject to contextual influences from the socio-political setting and from relationships between stakeholders Stakeholders involved in implementing strategies are bound to act based on their interests and previous courses of action To promote research uptake on the policy level, stakeholders and researchers need to engage in collaboration and translational activities Political stakeholders at the government and community levels need to be more directly involved as partners in the production and utilization of evidence.

In this prospective study of 135 patients undergoing cementless total hip arthroplasty (THA) we asked whether six current definitions of combined anteversion prevent impingement and increase postoperative patient individual impingement-free range-of-motion (ROM). Implant position was measured by an independent, external institute on 3D-CT performed six weeks post-operatively. Post-operative ROM was calculated using a CT-based algorithm detecting osseous and/or prosthetic impingement by virtual hip movement. Additionally, clinical ROM was evaluated pre-operatively and one-year post-operatively by a blinded observer. Combined component position of cup and stem according to the definitions of Ranawat, Widmer, Dorr, Hisatome and Yoshimine inhibited prosthetic impingement in over 90 %, while combined osseous and prosthetic impingement still occurred in over 40 % of the cases. The recommendations by Jolles, Widmer, Dorr, Yoshimine and Hisatome enabled higher flexion (p ≤ 0.001) and internal rotation (p ≤ 0.006). Clinically, anteversion rules of Widmer and Yoshimine provided one-year post-operatively statistically but not clinically relevant higher internal rotation (p ≤0.034). Standard rules of combined anteversion detect prosthetic but fail to prevent combined osseous and prosthetic impingement in THA. Future models will have to account for the patient-individual anatomic situation to ensure impingement-free ROM.

Typhoid fever: hurdles to adequate hand washing for disease prevention among the population of a peri-urban informal settlement in Fiji.

The Pacific island nation of Fiji Islands has high rates of endemic typhoid fever which is difficult to diagnose and often underreported. However, the majority of cases are preventable through use of safe water; adequate sanitation; vaccination; and, most sustainable of all, simple hygienic behaviour, such as hand washing with soap (HWWS). Despite many attempts by public health authorities, little progress has been made in the area of environmental adaptation and behaviour change. To explore perceptions of typhoid fever risk among urban squatters and behavioural determinants surrounding HWWS, indigenous Fijians living in informal settlements with high typhoid fever incidence were invited to participate in focus group discussions. In-depth interviews were conducted with community leaders. Perceptions of typhoid fever suggest confusion about risk factors, symptoms and communicability. Environmental barriers for hand washing were related to water and soap access. Standard social marketing approaches have been trialled with little clear evidence of impact. Despite this, we continue to advocate for the social and cultural determinants of typhoid prevention to remain central to future public health strategies. Despite behaviour change being notoriously difficult, we argue that community-driven behaviour adaptation initiatives based on sound epidemiological evidence and health communication theory are likely to have significant impact and greater likelihood of sustainability.

Healthy Love is a brief, highly interactive, single-session, group-level HIV prevention intervention designed for African American women that is effective at reducing sex risk behaviors and increasing condom use and HIV testing among participants. The Centers for Disease Control and Prevention, through a contract, developed a user-friendly intervention package that would allow organizations to adopt and implement Healthy Love with fidelity. Training and implementation materials were developed to support original research protocols, and piloted and revised to conduct field-testing with case study agencies (CSAs). Three CSAs were selected to deliver the intervention over a 3-month period to test the utility of intervention materials and feasibility of implementation. All CSAs were able to successfully deliver 10 sessions with a total of 185 women ranging from 18 to 59 years of age. Successes and challenges encountered in training, preimplementation activities, and intervention delivery are described. Lessons learned from training, technical assistance, and process monitoring and evaluation informed final package revisions. Research to practice recommendations are shared as is guidance for future implementations of Healthy Love. The research to practice process used is a model approach for developing a comprehensive intervention package and will support the adoption of Healthy Love by other organizations.

Lung cancer is the most common cancer in the world, therefore creating a huge public health concern. The aim of this study is to determine the change in age-standardised incidence rate trend of lung cancer in England between 2002 and 2011 and use these findings to anticipate the potential burden of the disease by gender in the year 2020. Lung cancer incidence data (ICD-10 code C33-34) from 2002 and 2011 and mid-year population estimates for the same period were obtained from Office of National Statistics. Age-standardised incidence rates were calculated, by gender and region. Poisson regression analysis was used to describe the time incidence trend and projections were estimated up to year 2020. A total of 318, 417 lung cancer cases were identified. Incidence rates decreased in men by an average annual percentage change (AAPC) of -1.0% and increased in women by +1.9%. Projection analysis showed that by year 2020, provided the rates remain the same, English women will have the same lung cancer incidence rates as their male counterparts. This study demonstrated that there would be 5,848 excess lung cancer cases by 2020 with female population accounting for 85% (4,996) of the excess cases. Therefore, in addition to the development of high quality preventive intervention strategies, future public health also needs to prioritise targets at the implementation phase, in a manner that engage women living in regions that have demonstrated very high AAPC values.

Human influenza infections display a strongly seasonal pattern. However, whether H7N9 and H5N1 infections correlate with climate factors has not been examined. Here, we analyzed 350 cases of H7N9 infection and 47 cases of H5N1 infection. The spatial characteristics of these cases revealed that H5N1 infections mainly occurred in the South, Middle, and Northwest of China, while the occurrence of H7N9 was concentrated in coastal areas of East and South of China. Aside from spatial-temporal characteristics, the most adaptive meteorological conditions for the occurrence of human infections by these two viral subtypes were different. We found that H7N9 infections correlate with climate factors, especially temperature (TEM) and relative humidity (RHU), while H5N1 infections correlate with TEM and atmospheric pressure (PRS). Hence, we propose a risky window (TEM 4-14 °C and RHU 65-95%) for H7N9 infection and (TEM 2-22 °C and PRS 980-1025 kPa) for H5N1 infection. Our results represent the first step in determining the effects of climate factors on two different virus infections in China and provide warning guidelines for the future when provinces fall into the risky windows. These findings revealed integrated predictive meteorological factors rooted in statistic data that enable the establishment of preventive actions and precautionary measures against future outbreaks.

Interactive Bio-feedback Therapy Using Hybrid Assistive Limbs for Motor Recovery after Stroke: Current Practice and Future Perspectives

MORISHITA, Takashi; INOUE, Tooru

2016-01-01

Interactive bio-feedback (iBF) was initially developed for the rehabilitation of motor function in patients with neurological disorders, and subsequently yielded the development of the hybrid assistive limb (HAL). Here, we provide a review of the theory underlying HAL treatment as well as our clinical experience and recommendations for future clinical studies using HAL in acute stroke patients. We performed a PubMed-based literature search, a retrospective data review of our acute stroke case series, and included a sample case report of our findings. Given past animal studies and functional imaging results, iBF therapy using the HAL in the acute phase of stroke seems an appropriate approach for preventing learned non-use and interhemispheric excitation imbalances. iBF therapy may furthermore promote appropriate neuronal network reorganization. Based on experiences in our stroke center, HAL rehabilitation is a safe and effective treatment modality for recovering motor impairments after acute stroke, and allows the design of tailored rehabilitation programs for individual patients. iBF therapy through the HAL system seems to be an effective and promising approach to stroke rehabilitation; however, the superiority of this treatment to conventional rehabilitation remains unclear. Further clinical studies are warranted. Additionally, the formation of a patient registry will permit a meta-analysis of HAL cases and address the problems associated with a controlled trial (e.g., the heterogeneity of an acute stroke cohort). The development of robotic engineering will improve the efficacy of HAL rehabilitation and has the potential to standardize patient rehabilitation practice. PMID:27616320

This paper sets out a way of thinking about how to prepare for and respond to droughts in a holistic way using a framework developed for managing floods. It shows how the multi-layered safety (MLS) approach for flood resilience can be utilised in the context of drought in a way that three layers of intervention can be distinguished for operationalising drought resilience: (1) protection against water shortage through augmentation and diversification of water supplies; (2) prevention of damage in case of water shortage through increased efficiency of water use and timely asset maintenance; (3) preparedness for future water shortages through mechanisms to reduce the use of water and adopt innovative water technologies. Application of MLS to the cities of Adelaide, Melbourne and Sydney shows that recent water reforms in these cities were primarily focused on protection measures that aim to reduce the hazard source or exposure to insufficient water supplies. Prevention and preparedness measures could be considered in defining interventions that aim to further increase the drought resilience of these cities. Although further research is needed, the application suggests that MLS can be applied to the context of drought risk management. The MLS framework can be used to classify the suite of plans deployed by a city to manage future drought risks and can be considered a planning tool to identify opportunities for increasing the level of redundancy and hence resilience of the drought risk management system.

Fetal and neonatal alloimmune thrombocytopenia is a potentially life-threatening disease with excellent preventative treatment available for subsequent pregnancies. To prevent index cases, the effectiveness of a population-based screening program has been suggested repeatedly. Therefore, we aimed to evaluate women's attitude towards possible future human platelet antigen-screening in pregnancy. We performed a cross-sectional questionnaire study among healthy pregnant women receiving prenatal care in one of seven participating midwifery practices. Attitude was assessed using a questionnaire based on the validated Multidimensional Measurement of Informed Choice model, containing questions assessing knowledge, attitude and intention to participate. A total of 143 of the 220 women (65%) completed and returned the questionnaire. A positive attitude towards human platelet antigen-screening was expressed by 91% of participants, of which 94% was based on sufficient knowledge. Attitude was more likely to be negatively influenced by the opinion that screening can be frightening. Informed choices were made in 87% and occurred significantly less in women from non-European origin, 89% in European women vs. 60% in non-European women (p = 0.03). Pregnant women in the Netherlands expressed a positive attitude towards human platelet antigen-screening in pregnancy. We therefore expect a high rate of informed uptake when human platelet antigen-screening is implemented. In future counseling on human platelet antigen-screening, ethnicity and possible anxiety associated with a screening test need to be specifically addressed. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

Use of clinical movement screening tests to predict injury in sport

Chimera, Nicole J; Warren, Meghan

2016-01-01

Clinical movement screening tests are gaining popularity as a means to determine injury risk and to implement training programs to prevent sport injury. While these screens are being used readily in the clinical field, it is only recently that some of these have started to gain attention from a research perspective. This limits applicability and poses questions to the validity, and in some cases the reliability, of the clinical movement tests as they relate to injury prediction, intervention, and prevention. This editorial will review the following clinical movement screening tests: Functional Movement Screen™, Star Excursion Balance Test, Y Balance Test, Drop Jump Screening Test, Landing Error Scoring System, and the Tuck Jump Analysis in regards to test administration, reliability, validity, factors that affect test performance, intervention programs, and usefulness for injury prediction. It is important to review the aforementioned factors for each of these clinical screening tests as this may help clinicians interpret the current body of literature. While each of these screening tests were developed by clinicians based on what appears to be clinical practice, this paper brings to light that this is a need for collaboration between clinicians and researchers to ensure validity of clinically meaningful tests so that they are used appropriately in future clinical practice. Further, this editorial may help to identify where the research is lacking and, thus, drive future research questions in regards to applicability and appropriateness of clinical movement screening tools.

According to WHO estimates, 35% of global measles deaths in 2011 occurred in India. In 2013, India committed to a goal of measles elimination by 2020. Laboratory supported case based measles surveillance is an essential component of measles elimination strategies. Results from a case-based measles surveillance system in Pune district (November 2009 through December 2011) are reported here with wider implications for measles elimination efforts in India. Standard protocols were followed for case identification, investigation and classification. Suspected measles cases were confirmed through serology (IgM) or epidemiological linkage or clinical presentation. Data regarding age, sex, vaccination status were collected and annualized incidence rates for measles and rubella cases calculated. Of the 1011 suspected measles cases reported to the surveillance system, 76% were confirmed measles, 6% were confirmed rubella, and 17% were non-measles, non-rubella cases. Of the confirmed measles cases, 95% were less than 15 years of age. Annual measles incidence rate was more than 250 per million persons and nearly half were associated with outbreaks. Thirty-nine per cent of the confirmed measles cases were vaccinated with one dose of measles vaccine (MCV1). Surveillance demonstrated high measles incidence and frequent outbreaks in Pune where MCV1 coverage in infants was above 90%. Results indicate that even high coverage with a single dose of measles vaccine was insufficient to provide population protection and prevent measles outbreaks. An effective measles and rubella surveillance system provides essential information to plan, implement and evaluate measles immunization strategies and monitor progress towards measles elimination.

Of the confirmed measles cases, 95% were less than 15 years of age. Annual measles incidence rate was more than 250 per million persons and nearly half were associated with outbreaks. Thirty-nine per cent of the confirmed measles cases were vaccinated with one dose of measles vaccine (MCV1). Conclusion Surveillance demonstrated high measles incidence and frequent outbreaks in Pune where MCV1 coverage in infants was above 90%. Results indicate that even high coverage with a single dose of measles vaccine was insufficient to provide population protection and prevent measles outbreaks. An effective measles and rubella surveillance system provides essential information to plan, implement and evaluate measles immunization strategies and monitor progress towards measles elimination.

Nutritional rickets and osteomalacia are common in dark-skinned and migrant populations. Their global incidence is rising due to changing population demographics, failing prevention policies and missing implementation strategies. The calcium deprivation spectrum has hypocalcaemic (seizures, tetany and dilated cardiomyopathy) and late hypophosphataemic (rickets, osteomalacia and muscle weakness) complications. This article reviews sustainable prevention strategies and identifies areas for future research. The global rickets consensus recognises the equal contribution of vitamin D and dietary calcium in the causation of calcium deprivation and provides a three stage categorisation for sufficiency, insufficiency and deficiency. For rickets prevention, 400 IU daily is recommended for all infants from birth and 600 IU in pregnancy, alongside monitoring in antenatal and child health surveillance programmes. High-risk populations require lifelong supplementation and food fortification with vitamin D or calcium. Future research should identify the true prevalence of rickets and osteomalacia, their role in bone fragility and infant mortality, and best screening and public health prevention tools.

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.

School truancy is a serious concern in the U.S., with far-reaching negative consequences. Truancy has been positively associated with substance use and delinquent behavior; however, research is limited. Consequently, the Truancy Brief Intervention Project was established to treat and prevent substance use and other risky behaviors among truants. This article examines whether the Brief Intervention program is more effective in preventing future delinquency over a 12-month follow-up period, than the standard truancy program. Results indicate the Brief Intervention was marginally significant in effecting future delinquency among truants, compared to the standard truancy program. Future implications of this study are discussed. PMID:25382960

Background: Opioids have narrow therapeutic windows, and errors in ordering or administration can be fatal. The purpose of this study was to describe deaths involving hydromorphone and morphine, which have similar-sounding names, but different potencies. Methods: In this case series, we describe deaths of patients admitted to hospital or residents of long-term care facilities that involved hydromorphone and morphine. We searched for deaths referred to the Patient Safety Review Committee of the Office of the Chief Coroner for Ontario between 2007 and 2012, and subsequently reviewed by 2014. We reviewed each case to identify intervention points where errors could have been prevented. Results: We identified 8 cases involving decedents aged 19 to 91 years. The cases involved errors in prescribing, order processing and transcription, dispensing, administration and monitoring. For 7 of the 8 cases, there were multiple (2 or more) possible intervention points. Six cases may have been prevented by additional patient monitoring, and 5 cases involved dispensing errors. Interpretation: Opioid toxicity deaths in patients living in institutions can be prevented at multiple points in the prescribing and dispensing processes. Interventions aimed at preventing errors in hydromorphone and morphine prescribing, administration and patient monitoring should be implemented and rigorously evaluated. PMID:28401133

Introduction Financing of malaria control for displaced populations is limited in scope and duration, making cost-effectiveness analyses relevant but difficult. This study analyses cost-effectiveness of adding prevention through targeted indoor residual spraying (IRS) to case management in Afghan refugee settlements in Pakistan during a prolonged malaria epidemic. Methods/Findings An intervention study design was selected, taking a societal perspective. Provider and household costs of vector control and case management were collected from provider records and community survey. Health outcomes (e.g. cases and DALYs averted) were derived and incremental cost-effectiveness ratios (ICERs) for cases prevented and DALYs averted calculated. Population, treatment cost, women’s time, days of productivity lost, case fatality rate, cases prevented, and DALY assumptions were tested in sensitivity analysis. Malaria incidence peaked at 44/1,000 population in year 2, declining to 14/1,000 in year 5. In total, 370,000 malaria cases, 80% vivax, were diagnosed and treated and an estimated 67,988 vivax cases and 18,578 falciparum and mixed cases prevented. Mean annual programme cost per capita was US$0.56. The additional cost of including IRS over five years per case prevented was US$39; US$50 for vivax (US$43 in years 1–3, US$80 in years 4–5) and US$182 for falciparum (US$139 in years 1–3 and US$680 in years 4–5). Per DALY averted this was US$266 (US$220 in years 1–3 and US$486 in years 4–5) and thus ‘highly cost-effective’ or cost-effective using WHO and comparison thresholds. Conclusions Adding IRS was cost-effective in this moderate endemicity, low mortality setting. It was more cost-effective when transmission was highest, becoming less so as transmission reduced. Because vivax was three times more common than falciparum and the case fatality rate was low, cost-effectiveness estimations for cases prevented appear reliable and more definitive for vivax malaria.

To review the causes of death in patients admitted via the emergency department (ED) who died within 7 days of admission and to identify any ways in which ED care could have been better. The study also aims to compare the diagnosis made in the ED and the mortality diagnosis. A retrospective study; subjects were all patients who attended the ED over 4 months and died within 7 days of admission. The paramedics' notes, ED case cards, inpatient medical notes and details of postmortem findings were examined to identify the time and date of arrival in the ED, presenting complaint, provisional diagnosis made by the ED, treatment plan devised by the ED, diagnosis made in wards, and the cause of death as issued on death certificates or from postmortem findings. Summary sheets of cases where the care provided by the emergency department could have been improved were reviewed, errors were identified and deaths were classified as preventable or unpreventable. Database revealed 3521 admissions via the ED over 4 months, of which 95 cases (2.69%) died within 7 days of admission. 78 patients (82.1% of cases) were appropriately diagnosed and managed whereas 17 (17.87% of cases) were identified with deficiencies in either the diagnosis or the management provided in the ED. We reviewed the quality of care provided in the ED for these cases and rated deaths according to our preventability criteria: 5 (5.26%) deaths were unpreventable despite the deficiency in care provided in the ED; 3 (3.15%) deaths were definitely preventable; 3 (3.15%) were probably preventable; and 6 (6.31%) were possibly preventable deaths. The ED is playing a good role in the management of critically ill patients, with appropriate diagnosis and management in 82% of cases. Training of junior doctors is required to prevent occurrence of errors and thus preventable deaths, but all deaths are not preventable. New guidelines for sepsis management and management of undifferentiated clinical presentations are being introduced and we intend to audit the implications of new guidelines.

Using mobile devices, such as personal digital assistants (PDAs), smartphones, tablet computers, etc., to electronically collect malaria-related field data is the way for the field questionnaires in the future. This case study seeks to design a generic survey framework PDA-based geo-tagged malaria-related data collection tool (PGMS) that can be used not only for large-scale community-level geo-tagged electronic malaria-related surveys, but also for a wide variety of electronic data collections of other infectious diseases. The framework includes two parts: the database designed for subsequent cross-sectional data analysis and the customized programs for the six study sites (two in Kenya, three in Indonesia, and one in Tanzania). In addition to the framework development, we also present our methods used when configuring and deploying the PDAs to 1) reduce data entry errors, 2) conserve battery power, 3) field install the programs onto dozens of handheld devices, 4) translate electronic questionnaires into local languages, 5) prevent data loss, and 6) transfer data from PDAs to computers for future analysis and storage. Since 2008, PGMS has successfully accomplished quite a few surveys that recorded 10,871 compounds and households, 52,126 persons, and 17,100 bed nets from the six sites. These numbers are still growing. © The American Society of Tropical Medicine and Hygiene.

Has Rift Valley fever virus evolved with increasing severity in human populations in East Africa?

Baba, Marycelin; Masiga, Daniel K; Sang, Rosemary; Villinger, Jandouwe

2016-01-01

Rift Valley fever (RVF) outbreaks have occurred across eastern Africa from 1912 to 2010 approximately every 4–15 years, most of which have not been accompanied by significant epidemics in human populations. However, human epidemics during RVF outbreaks in eastern Africa have involved 478 deaths in 1998, 1107 reported cases with 350 deaths from 2006 to 2007 and 1174 cases with 241 deaths in 2008. We review the history of RVF outbreaks in eastern Africa to identify the epidemiological factors that could have influenced its increasing severity in humans. Diverse ecological factors influence outbreak frequency, whereas virus evolution has a greater impact on its virulence in hosts. Several factors could have influenced the lack of information on RVF in humans during earlier outbreaks, but the explosive nature of human RVF epidemics in recent years mirrors the evolutionary trend of the virus. Comparisons between isolates from different outbreaks have revealed an accumulation of genetic mutations and genomic reassortments that have diversified RVF virus genomes over several decades. The threat to humans posed by the diversified RVF virus strains increases the potential public health and socioeconomic impacts of future outbreaks. Understanding the shifting RVF epidemiology as determined by its evolution is key to developing new strategies for outbreak mitigation and prevention of future human RVF casualties. PMID:27329846

Ischemic Stroke: From Next Generation Sequencing and GWAS to Community Genomics?

PubMed

Black, Michael; Wang, Wenzhi; Wang, Wei

2015-08-01

Stroke is a major cause of mortality and morbidity in both the developed and developing world. Next generation sequencing (NGS) and multi-omics integrative biology research offer new opportunities in the way we research and understand stroke. These biotechnologies also signal a shift from genetics to genomics of stroke, which is highlighted in this review. Stroke is a focal neurological deficit resulting from disruption of the cerebral blood supply. There are two main types of common stroke, ischemic stroke (IS), which comprises 80% of cases, and hemorrhagic stroke (HS) that accounts for about 20% of cases. IS is a complex multi-factorial disease with multiple environmental and genomic determinants. We discuss here IS from genomics and bioinformatics perspectives, including the highlights of the genome wide association studies (GWAS), NGS progress to date, and exome studies. While both 'common variant, common disease' and 'rare variant, common disease' approaches need to be assessed in tandem, future studies into IS omics should also consider pedigree and/or community based sampling to take account of the complex diversity of IS genetics. We conclude by presenting an example of such community genomics research from China in an extended pedigree sample, and the ways in which the intersection of genomics and global society can usefully inform our understanding of IS pathophysiology and potential preventive medicine interventions in the future.

Despite much progress in the management of malignant diseases, the number of new cases and cancer-related deaths continues to rise around the world. More than half of new cases occur in economically developing countries, where more than two thirds of cancer deaths are expected. However, implementation of all necessary steps to accomplish the dissemination of state-of-the-art prevention, diagnosis, and management will require increased allocation of resources, and, more importantly, harmonization of the efforts of hundreds of national and international public health agencies, policy-setting bodies, governments, pharmaceutical companies, and philanthropic organizations. More than 30% of the members of the American Society of Clinical Oncology (ASCO) reside and practice outside US borders, and more than half of attendees at all of the scientific congresses and symposia organized by ASCO are international. As cancer has become an increasingly global disease, ASCO has evolved as a global organization. The ASCO Board of Directors currently includes members from France, Brazil, and Canada. In 2013, the ASCO Board of Directors identified a number of strategic priorities for the future. Recognizing the importance of non-US members to the society, their first strategic priority was improving the society's service to non-US members and defining these members' identity in the international oncology community. This article reviews current ASCO activities in the international arena and its future plans in global oncology. PMID:26578614

Implementing Statewide Severe Maternal Morbidity Review: The Illinois Experience.

2018-03-07

Severe maternal morbidity (SMM) rates in the United States more than doubled between 1998 and 2010. Advanced maternal age and chronic comorbidities do not completely explain the increase in SMM or how to effectively address it. The Centers for Disease Control and Prevention and American College of Obstetricians and Gynecologists have called for facility-level multidisciplinary review of SMM for potential preventability and have issued implementation guidelines. Within Illinois, SMM was identified as any intensive or critical care unit admission and/or 4 or more units of packed red blood cells transfused at any time from conception through 42 days postpartum. All cases meeting this definition were counted during statewide surveillance. Cases were selected for review on the basis of their potential to yield insights into factors contributing to preventable SMM or best practices preventing further morbidity or death. If the SMM review committee deemed a case potentially preventable, it identified specific factors associated with missed opportunities and made actionable recommendations for quality improvement. Approximately 1100 cases of SMM were identified from July 1, 2016, to June 30, 2017, yielding a rate of 76 SMM cases per 10 000 pregnancies. Reviews were conducted on 142 SMM cases. Most SMM cases occurred during delivery hospitalization and more than half were delivered by cesarean section. Hemorrhage was the primary cause of SMM (>50% of the cases). Facility-level SMM review was feasible and acceptable in statewide implementation. States that are planning SMM reviews across obstetric facilities should permit ample time for translation of recommendations to practice. Although continued maternal mortality reviews are valuable, they are not sufficient to address the increasing rates of SMM and maternal death. In-depth multidisciplinary review offers the potential to identify factors associated with SMM and interventions to prevent women from moving along the continuum of severity.

To better understand lightning deaths, a retrospective review of electronic records from New Mexico's Office of the Medical Investigator database was performed between 1977 and 2009 to update and assess current risk factors. Information on demographics, circumstances, autopsy, and death certificates were collected and analyzed. Fifty-four decedents were identified, ages 2-71 years old (mean 34 years old), 42 males and 12 females. Common racial/ethnic groups were non-Hispanic Whites and American Indians (together comprising 72% of all cases). Physical findings were often related to the heat carried by the electrical current including clothing alterations (29.6%) and burning of skin (53.7%). Most deaths occurred on weekend afternoons in summer months, associated with recreational activities or agricultural work, and rural locations (77.8%). Utilizing the demographic information, clustered events, and associated outdoor activities will assist in creating public awareness and provide a framework to support targeted warnings in an attempt to prevent future deaths. © 2014 American Academy of Forensic Sciences.

Staphylococcal toxic shock syndrome (TSS) was originally described in menstruating women and linked to TSS toxin 1 (TSST-1)-producing Staphylococcus aureus. Using UK national surveillance data, we ascertained clinical, molecular and superantigenic characteristics of TSS cases. Average annual TSS incidence was 0.07/100,000 population. Patients with nonmenstrual TSS were younger than those with menstrual TSS but had the same mortality rate. Children <16 years of age accounted for 39% of TSS cases, most caused by burns and skin and soft tissue infections. Nonmenstrual TSS is now more common than menstrual TSS in the UK, although both types are strongly associated with the tst+ clonal complex (CC) 30 methicillin-sensitive S. aureus lineage, which accounted for 49.4% of all TSS and produced more TSST-1 and superantigen bioactivity than did tst+ CC30 methicillin-resistant S. aureus strains. Better understanding of this MSSA lineage and infections in children could focus interventions to prevent TSS in the future.

In 2001, Maryland’s court of appeals was asked to decide whether researchers at Johns Hopkins University had engaged in unethical research on children. During the 1990s, Johns Hopkins’s Kennedy Krieger Institute had studied 108 African American children, aged 6 months to 6 years, to find an inexpensive and “practical” means to ameliorate lead poisoning. We have outlined the arguments in the case and the conundrum faced by public health researchers as they confront new threats to our health from environmental and industrial insults. We examined the case in light of contemporary public health ideology, which prioritizes harm reduction over the historical goals of prevention. As new synthetic toxins—such as bisphenyl A, polychlorinated biphenyls, other chlorinated hydrocarbons, tobacco, vinyl, and asbestos—are discovered to be biologically disruptive and disease producing at low levels, lead provides a window into the troubling dilemmas public health will have to confront in the future.

Purpose of review In this article, we review the indications and latest management of high-risk penetrating keratoplasty. Recent findings Despite the immune-privilege status of the cornea, immune-mediated graft rejection still remains the leading cause of corneal graft failure. This is particularly a problem in the high-risk graft recipients, namely patients with previous graft failure due to rejection and those with inflamed and vascularized corneal beds. A number of strategies including both local and systemic immunosuppression are currently used to increase the success rate of high-risk corneal grafts. Moreover, in cases of limbal stem cell deficiency, limbal stem cells transplantation is employed. Summary Corticosteroids are still the top medication for prevention and treatment in cases of corneal graft rejection. Single and combined administration of immunosuppressive agents e.g. tacrolimus, cyclosporine and mycophenolate are promising adjunctive therapies for prolonging graft survival. In the future, cellular and molecular therapies should allow us to achieve immunologic tolerance even in high-risk grafts. PMID:28959505

This case study describes the implementation of an academic institution's disaster management plan. Case study. USFQ's Medical School developed a six-phase disaster relief plan consisting of: induction, establishing a base camp, crisis management and mental health aid, creation of multidisciplinary teams and multi-agency teams, and reconstruction. Each phase uses a community-oriented approach to foster survivor autonomy and recovery. Our methodology facilitated the successful implementation of multidisciplinary interventions to manage the earthquake's aftermath on the personal, community and regional levels, treated and prevented psychological and physical morbidity among survivors and promoted healthy living conditions and independence. A multidisciplinary response team that addresses medical needs, mental health, education, food, nutrition and sanitation is highly effective in contributing to timely, effective relief efforts. The short- and long-term solutions we describe could be applicable to other academic centres' interventions in future disaster scenarios around the world.

To detail the presentation of an elite male ice hockey goaltender with cam-type femoroacetabular impingement (FAI) and acetabular labral tears. This case will outline the prevalence, clinical presentation, imaging criteria, pathomechanics, and management of FAI, with specific emphasis on the ice hockey goaltender. A 22-year old retired ice hockey goaltender presented to a chiropractor after being diagnosed by an orthopaedic surgeon with MRI confirmed left longitudinal and chondral flap acetabular labral tears and cam-type femoroacetabular impingement (FAI). As the patient was not a candidate for surgical intervention, a multimodal conservative treatment approach including manual therapy, electroacupuncture and rehabilitation exercises were implemented. FAI is prevalent in ice hockey players, particularly with goaltenders. Both skating and position-dependent hip joint mechanics involved in ice hockey may exacerbate or contribute to acquired and congenital forms of symptomatic FAI. As such, practitioners managing this population must address sport-specific demands in manual therapy, rehabilitation and physical training, to improve functional outcomes and prevent future injury.

I explored the structural and operational practices of the chronic disease prevention and control unit of a state health department and proposed a conceptual model of structure, function, and effectiveness for future study. My exploratory case study examined 7 elements of organizational structure and practice. My interviews with staff and external stakeholders of a single chronic disease unit yielded quantitative and qualitative data that I coded by perspective, process, relationship, and activity. I analyzed these for patterns and emerging themes. Chi-square analysis revealed significant correlations among collaboration with goal ambiguity, political support, and responsiveness, and evidence-based decisions with goal ambiguity and responsiveness. Although my study design did not permit conclusions about causality, my findings suggested that some elements of the model might facilitate effectiveness for chronic disease units and should be studied further. My findings might have important implications for identifying levers around which capacity can be built that may strengthen effectiveness.

An international seminar on the treatment and laboratory diagnosis of yellow fever, sponsored by the Pan American Health Organization (PAHO) and held in 1984, differed from previous meetings on yellow fever because of its emphasis on the care and management of patients and because the participants included specialists from several branches of medicine, such as hepatology, haematology, cardiology, infectious diseases, pathology and nephrology. The meeting reviewed the current status of yellow fever and problems associated with case-finding and notification; features of yellow fever in individual countries of Latin America; health services and facilities for medical care as they relate to diagnosis and management of cases; prevention strategies for and current status of immunization programmes; clinical and pathological aspects of yellow fever in humans; pathogenesis and pathophysiology of yellow fever in experimental animal models; clinical and specific laboratory diagnosis; treatment of the disease and of complications in the functioning of individual organ systems; prognosis and prognostic indicators; and directions for future clinical and experimental research on pathophysiology and treatment.

Tuberculosis (TB) is a major public health issue worldwide, with ~9.6 million new incident cases and 1.5 million deaths in 2014. The End-TB Strategy launched by the World Health Organization in the context of the post-2015 agenda aims to markedly abate the scourge of TB towards global elimination, by improving current diagnostic and therapeutic practices, promoting preventative interventions, stimulating government commitment and increased financing, and intensifying research and innovation. The emergence and spread of multidrug-resistant strains is currently among the greatest concerns, which may hinder the achievement of future goals. It is crucial that primary healthcare providers are sufficiently familiar with the basic principles of TB diagnosis and care, to ensure early case detection and prompt referral to specialised centres for treatment initiation and follow-up. Given their special relationship with patients, they are in the best position to promote educational interventions and identify at-risk individuals as well as to improve adherence to treatment.

2011-08-01

Postpartum haemorrhage (PPH) remains a significant cause of maternal morbidity and mortality in both developed and developing countries. In some instances, PPH can be anticipated and recent improvements in obstetric imaging techniques allow earlier and more reliable diagnosis of abnormalities associated with haemorrhage such as morbid placentation. However, the majority of PPH is unpredicted. Good practice notes published by the Royal College of Obstetricians and Gynaecologists state interventional radiology should be used as emergency intervention in PPH and should be considered when primary management has failed allowing arteries to be embolised to achieve haemostasis. Through collaboration between interventional radiology and maternity, appropriate guidelines need to be developed, on both emergency and elective of interventional radiology in the prevention and management of PPH. As there is mapping for neonatal services, in the future there should be consideration to develop obstetric trauma units. Maternity units which lack facilities for interventional radiology would be able to refer their cases (like placenta accreta) for safe management in units with 24 h interventional radiology services.

The limited success of youth violence prevention interventions suggests that effective prevention needs to address causes at multiple levels of analysis and empower youth in developing and implementing prevention programs. In this article, we review published studies of youth violence prevention efforts that engage youth in developing or implementing violence prevention activities. The reviewed studies suggest the promise of youth empowerment strategies and the need for systematic outcome studies of empowerment programs. After reviewing empowerment theory applied to youth violence prevention programs, we present a case study of the Youth Empowerment Solutions (YES) for Peaceful Communities program. YES engages middle-school youth in an after-school and summer program that includes a culturally tailored character development curriculum and empowers the youth to plan and implement community improvement projects with assistance from adult neighborhood advocates. The case study focuses on outcome evaluation results and presents evidence of the YES program effects on community-level outcomes (eg, property improvements, violent crime incidents) and on individual-level outcomes (eg, conflict avoidance, victimization). The literature review and the case study suggest the promise of engaging and empowering youth to plan and implement youth violence prevention programs.

In this study, the authors examined the prevalence and cost of care for children enrolled in Medicaid for potentially preventable dental conditions who receive surgical care in hospital operating rooms (ORs) or ambulatory surgery centers (ASCs). The authors analyzed Medicaid data from 8 states to find cases in which children aged 1 to 20 years received surgical care in ORs or ASCs in 2010 and 2011 for potentially preventable diagnoses, as defined with diagnostic codes. For 6 states with complete data, there were 26,373 cases in 2011 in which children received OR or ASC surgical care for potentially preventable conditions. These cases represent approximately 0.5% of all children enrolled in Medicaid in these states and approximately 1% of children enrolled in Medicaid who received any dental care. There were $68 million in total Medicaid payments for these cases, with an average of $2,581 per case. Diagnostic codes indicated that 98% of cases were related to treatment of dental caries. More than two-thirds of the cases (71%) were children aged 1 to 5 years. Extrapolation to the United States suggests that approximately $450 million in additional expenditures occurred in 2011 because of OR or ASC surgical care for potentially preventable pediatric dental conditions, primarily related to early childhood caries. Strategies to improve prevention of early childhood caries, including community- and family-based education, and to increase access to timely and early dental care for low-income children could reduce the burdens and costs of these dental problems.

Albinism and lung fibrosis in a young man - the first case of adult Hermansky-Pudlak Syndrome reported in Malaysia.

PubMed

Liza, A F; Aziah, A M

2012-12-01

A young gentleman of Indian descent with oculacutaneous albinism (OCA) was found to have severe pulmonary fibrosis at first presentation. Following investigations, he was diagnosed with Hermansky-Pudlak Syndrome (HPS). It is a genetic condition characterised by albinism, bleeding diathesis and multisystem disorder observed in individuals of particular descents. Although there is no curative treatment apart from lung transplantation, preventive measures to minimise pulmonary insult may change the natural history of the disease. Therefore HPS should be actively sought, monitored and risk factors addressed in individuals with OCA and bleeding diathesis particularly those of Indian descent as they may develop serious complications such as pulmonary fibrosis in the future.

Epidemiology and pathogenesis of Bolivian hemorrhagic fever.

Patterson, Michael; Grant, Ashley; Paessler, Slobodan

2014-04-01

The etiologic agent of Bolivian hemorrhagic fever (BHF), Machupo virus (MACV) is reported to have a mortality rate of 25-35%. First identified in 1959, BHF was the cause of a localized outbreak in San Joaquin until rodent population controls were implemented in 1964. The rodent Calomys collosus was identified as the primary vector and reservoir for the virus. Multiple animal models were considered during the 1970s with the most human-like disease identified in Rhesus macaques but minimal characterization of the pathogenesis has been published since. A reemergence of reported BHF cases has been reported in recent years, which necessitates the further study and development of a vaccine to prevent future outbreaks. Copyright © 2014 Elsevier B.V.

Sidhu, K S; Collisi, M B

1989-02-01

A veterinary technician while opening a package was accidentally exposed to a commercial canned product formulation containing insecticides and solvents. The patient was twice briefly treated and released as an outpatient from 2 different hospitals on the first and second day after the exposure. However, on the fourth day, as some of the symptoms (headache, nausea, vomiting, diarrhea, difficult breathing) persisted, the patient was admitted to another hospital. The patient was treated for exposure to organophosphates and solvents and was released after 13 days. The patient developed diabetes insipidus, a condition which lasted for approximately 1 year. The cause of the temporary development of diabetes insipidus is not understood. There is a need to prevent and minimize such accidental exposures in future.

Polyomavirus-Specific Cellular Immunity: From BK-Virus-Specific Cellular Immunity to BK-Virus-Associated Nephropathy?

Dekeyser, Manon; François, Hélène; Beaudreuil, Séverine; Durrbach, Antoine

2015-01-01

In renal transplantation, BK-virus (BKV)-associated nephropathy has emerged as a major complication, with a prevalence of 1–10% and graft loss in >50% of cases. BKV is a member of the polyomavirus family and rarely induces apparent clinical disease in the general population. However, replication of polyomaviruses, associated with significant organ disease, is observed in patients with acquired immunosuppression. Monitoring of specific immunity combined with viral load could be used to individually assess the risk of viral reactivation and virus control. We review the current knowledge on BKV-specific cellular immunity and, more specifically, in immunocompromised patients. In the future, immune-based therapies could allow us to treat and prevent BKV-associated nephropathy. PMID:26136745

Frozen chips: an unusual cause of severe frostbite injury

PubMed Central

Graham, C.; Stevenson, J.

2000-01-01

A case of severe frostbite injury to the right foot is presented. This was caused by the inappropriate application of a bag of frozen chips to the foot in an attempt to ease non-specific pain. No specific acute traumatic injury was identified. As the patient was a teacher of physical education, the pain had initially been assumed to originate from a minor musculoskeletal injury. Full recovery ensued after surgical excision of necrotic tissue and split skin grafting. The danger of inappropriate overenthusiastic use of ice packs or other frozen material to treat soft tissue injuries is emphasised. The need for education to prevent similar future injuries is discussed. Key Words: cold injury; frostbite; ice pack; skin; necrosis PMID:11049150

Existential Risk and Cost-Effective Biosecurity

In the decades to come, advanced bioweapons could threaten human existence. Although the probability of human extinction from bioweapons may be low, the expected value of reducing the risk could still be large, since such risks jeopardize the existence of all future generations. We provide an overview of biotechnological extinction risk, make some rough initial estimates for how severe the risks might be, and compare the cost-effectiveness of reducing these extinction-level risks with existing biosecurity work. We find that reducing human extinction risk can be more cost-effective than reducing smaller-scale risks, even when using conservative estimates. This suggests that the risks are not low enough to ignore and that more ought to be done to prevent the worst-case scenarios. PMID:28806130

Differences in the Management of Pediatric Facial Trauma

Braun, Tara L.; Xue, Amy S.; Maricevich, Renata S.

Craniofacial trauma is common in the pediatric population, with most cases limited to soft tissue and dentoalveolar injury. Although facial fractures are relatively rare in children compared with adults, they are often associated with severe injury and cause significant morbidity and disability. Initial evaluation of a child with facial trauma generally involves stabilizing the patient and identifying any severe concomitant injuries before diagnosing and managing facial injuries. The management of pediatric facial fractures is relatively more conservative than that of adults, and nonsurgical management is preferred when possible to prevent the disruption of future growth and development. Outcomes depend on the site of the injury, management plan, and subsequent growth, so children must be followed longitudinally for monitoring and the identification of any complications.

[Cartilage regeneration surgery on the hip : What is feasible?

PubMed

Landgraeber, Stefan; Jäger, Marcus; Fickert, Stefan

2017-11-01

Localized cartilage defects at the hip are mainly caused by pre-arthritic deformities, particularly by cam-type femoroacetabular impingement (FAI). Timely elimination of symptomatic deformities can prevent further progression such as cartilage defects. As the defects mostly occur in the anterolateral part of the acetabulum, they can be easily treated either by open surgery or by arthroscopy. To date the most effective methods of treatment are bone marrow stimulation, with or without a covering of biomaterials, and autologous chondrocyte transplantation. In selected cases, readaptation of the damaged cartilage can be attempted by biological procedures. In the present article, the findings reported in current studies on these procedures are summarized and discussed in detail. An outlook is given regarding possible future treatment concepts.
