    To review literature reporting adverse events and physiological instability in order to develop frameworks that describe and define clinical deterioration in hospitalised patients. Literature review of publications from 1960 to August 2012. Conception and refinement of models to describe clinical deterioration based on prevailing themes that developed chronologically in adverse event literature. We propose four frameworks or models that define clinical deterioration and discuss the utility of each. Early attempts used retrospective chart review and focussed on the end result of deterioration (adverse events) and iatrogenesis. Subsequent models were also retrospective, but used discrete complications (e.g. sepsis, cardiac arrest) to define deterioration, had a more clinical focus, and identified the concept of antecedent physiological instability. Current models for defining clinical deterioration are based on the presence of abnormalities in vital signs and other clinical observations and attempt to prospectively assist clinicians in predicting subsequent risk. However, use of deranged vital signs in isolation does not consider important patient-, disease-, or system-related factors that are known to adversely affect the outcome of hospitalised patients. These include pre-morbid function, frailty, extent and severity of co-morbidity, nature of presenting illness, delays in responding to deterioration and institution of treatment, and patient response to therapy. There is a need to develop multiple-variable models for deteriorating ward patients similar to those used in intensive care units. Such models may assist clinician education, prospective and real-time patient risk stratification, and guide quality improvement initiatives that prevent and improve response to clinical deterioration.

    To evaluate the efficacy of two office-based treatments designed to prevent deterioration in glycemic control in young adolescents with type 1 diabetes in a randomized clinical trial. An individualized, more intensive family teamwork Coping skills program was compared with a diabetes Education treatment. A baseline assessment was followed by four brief treatment sessions and immediate posttesting over the course of 1.5 years. Families of 226 early adolescents (ages 11-14) were randomized to receive either individualized coping skills education or diabetes education as adjunctive treatment to quarterly medical appointments. Continued follow-up occurred at 3.5-month intervals for a long-term follow-up of up to 3 years. A post hoc Usual Care group facilitated comparisons of glycemic control. Growth curve analysis showed that both treatment groups successfully prevented deterioration in adolescent disease care and simultaneously improved adolescent and parent quality of life that included indicators of more effective communication and reduced adherence barriers-without a concomitant increase in diabetes-related or general family conflict. However, contrary to expectation, the Education group was more efficacious than the Coping group in improvement of disease adherence and glycemic control over a 3-year follow-up. Low-intensity office-based quarterly treatment can maintain or improve disease care adherence in early adolescence when provided to adolescent/parent dyads. Better outcomes are achieved when treatment goals and techniques match the needs of the targeted population. © 2014 by the American Diabetes Association.

    Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), both abundant in fish oil, are known to have significant biochemical and physiological effects primarily linked to the improvement of human health, especially cardiovascular and brain health. However, the incorporation of fish oil into foods and beverages is often challenging, as fish oil is very easily oxidized and can cause undesirable flavors. This review discusses this rapid formation of the fishy and metallic off-flavors, focusing especially on an early stage of fish oil oxidation. Although oxidative stability and quality of commercialized fish oil have improved over the past few years, there is a still a problem with its application: Flavor deterioration can be found even at very low oxidation levels. This review also notes the effective way to inhibit the formation of the volatile compounds responsible for the flavor deterioration.

    Full Text Available Anne M Keogh, Andrew Jabbour, Christopher S Hayward, Peter S MacdonaldHeart Lung Transplant Unit, St Vincent’s Hospital, Sydney, New South Wales, AustraliaAbstract: Sildenafil is a selective inhibitor of phosphodiesterase type 5 (PDE-5. Its chronic administration has been shown to improve exercise capacity, World Health Organization functional class, and haemodynamics in patients with symptomatic pulmonary arterial hypertension (PAH. There is however, no data describing the clinical consequences of sudden cessation of sildenafil treatment. In this series, 9 patients with NYHA Class II–IV PAH who were stable on 2 months of sildenafil monotherapy, had their sildenafil ceased to accommodate a 2-week washout period, required for enrollment in research involving an endothelin receptor antagonist. Six minute walk distance (SMWD and clinical assessments were performed before cessation of sildenafil, and again 2 weeks later. Over the course of this 2-week washout period, 6 of the 9 patients reported increased breathlessness and fatigue, 1 of these was hospitalized with worsening right heart failure. The SMWD fell in 6 patients, with falls of greater than 100 m recorded in 4 patients. This was accompanied by a worsening of NYHA Class from 2.5 ± 0.2 to 3.1 ± 0.1 (mean ± SEM, p = 0.01. These data indicate that sudden cessation of sildenafil monotherapy, in patients with PAH, carries with it a significant and unpredictable risk of rapid clinical deterioration. We recommend that if sildenafil needs to be ceased, it would be more prudent to consider concurrent vasodilator therapy before the gradual cessation of sildenafil.Keywords: sildenafil, pulmonary hypertension, phosphodiesterase inhibitor

    To obtain an understanding of how Hospital in the Home (HITH) nurses recognise and respond to clinical deterioration in patients receiving care at home or in their usual place of residence. Recognising and responding to clinical deterioration is an international safety priority and a key nursing responsibility. Despite an increase in care delivery in home environments, how HITH nurses recognise and respond to clinical deterioration is not yet fully understood. A prospective, descriptive exploratory design was used. A survey containing questions related to participant characteristics and 10 patient scenarios was used to collect data from 47 nurses employed in the HITH units of three major health services in Melbourne, Australia. The 10 scenarios reflected typical HITH patients and included medical history and clinical assessment findings (respiratory rate, oxygen saturation, heart rate, blood pressure, temperature, conscious state and pain score). The three major findings from this study were that: (i) nurse and patient characteristics influenced HITH nurses' assessment decisions; (ii) the cues used by HITH nurses to recognise clinical deterioration varied according to the clinical context; and (iii) although HITH nurses work in an autonomous role, they engage in collaborative practice when responding to clinical deterioration. Hospital in the Home nurses play a fundamental role in patient assessment, and the context in which they recognise and respond to deterioration is markedly different to that of hospital nurses. The assessment, measurement and interpretation of clinical data are a nursing responsibility that is crucial to early recognition and response to clinical deterioration. The capacity of HITH services to care for increasing numbers of patients in their home environment, and to promptly recognise and respond to clinical deterioration should it occur, is fundamental to safety within the healthcare system. Hospital in the Home nurses are integral to a

    It is unclear how often lumbar puncture (LP) is complicated by cerebral herniation in patients with bacterial meningitis and whether cranial CT can be used to identify patients at risk for herniation. We performed a nationwide prospective cohort study of patients with community-acquired bacterial meningitis from 2006 to 2014 and identified patients with clinical deterioration possibly caused by LP. For systematic evaluation of contraindications for LP on cranial CT, these patients were matched to patients in the cohort without deterioration. Four experts, blinded for outcome, scored cranial CT results for contraindications for LP. A Fleiss' generalized Kappa for this assessment was determined. Of 1533 episodes, 47 (3.1%) had deterioration possibly caused by LP. Two patients deteriorated within 1 hour after LP (0.1%). In 43 of 47 patients with deterioration cranial CT was performed prior to LP, so CT results were matched with 43 patients without deterioration. The interrater reliability of assessment of contraindications for LP on cranial CT was moderate (Fleiss' generalized Kappa 0.47). A contraindication for LP was reported by all 4 raters in 6 patients with deterioration (14%) and in 5 without deterioration (11%). LP can be performed safely in the large majority of patients with bacterial meningitis, as it is only very rarely complicated by cerebral herniation. Cranial CT can be considered a screening method for contraindications for LP, but the interrater reliability of this assessment is moderate.

    Objective: ECG dispersion mapping (ECG-DM) is a novel technique that reports abnormal ECG microalternations. We report the ability of ECG-DM to predict clinical deterioration of acutely ill medical patients, as measured by an increase in the Simple Clinical Score (SCS) the day after admission to hospital. Methods: 453 acutely ill medical patients (mean age 69.7 +\\/- 14.0 years) had the SCS recorded and ECGDM performed immediately after admission to hospital. Results: 46 patients had an SCS increase 20.8 +\\/- 7.6 hours after admission. Abnormal micro-alternations during left ventricular re-polarization had the highest association with SCS increase (p=0.0005). Logistic regression showed that only nursing home residence and abnormal micro-alternations during re-polarization of the left ventricle were independent predictors of SCS increase with an odds ratio of 2.84 and 3.01, respectively. Conclusion: ECG-DM changes during left ventricular re-polarization are independent predictors of clinical deterioration the day after hospital admission.

    2015-01-01

    Despite the fact that the fields of pull type production control policies and condition-based preventive maintenance have much in common contextually, they have evolved independently up to now. In this investigation, an attempt is made to bridge the gap between these two branches of knowledge by introducing the single-stage Kanban system with deterioration failures and condition-based preventive maintenance. The formalism of continuous time Markov chains is used to model the system and expressions for eight performance metrics are derived. Two important, from a managerial perspective, constrained optimization problems for the proposed model are defined where the objective is the simultaneous optimization of the Kanban policy, the preventive maintenance policy and the inspection schedule under conflicting performance criteria. Multiple instances of each optimization problem are solved by means of the augmented Lagrangian genetic algorithm. The results from the optimization trials coupled by the results from extensive numerical examples facilitate the thorough investigation of the system’s behaviour. - Highlights: • Kanban system with deterioration failures and preventive maintenance is introduced. • The system is modeled as a continuous time Markov chain. • Expressions for eight performance metrics are derived. • The behavior of the system is studied through numerical examples. • Optimization results for selected performance metrics are presented

    2017-01-01

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

  18. Performance deterioration modeling and optimal preventive maintenance strategy under scheduled servicing subject to mission time

    Full Text Available Servicing is applied periodically in practice with the aim of restoring the system state and prolonging the lifetime. It is generally seen as an imperfect maintenance action which has a chief influence on the maintenance strategy. In order to model the maintenance effect of servicing, this study analyzes the deterioration characteristics of system under scheduled servicing. And then the deterioration model is established from the failure mechanism by compound Poisson process. On the basis of the system damage value and failure mechanism, the failure rate refresh factor is proposed to describe the maintenance effect of servicing. A maintenance strategy is developed which combines the benefits of scheduled servicing and preventive maintenance. Then the optimization model is given to determine the optimal servicing period and preventive maintenance time, with an objective to minimize the system expected life-cycle cost per unit time and a constraint on system survival probability for the duration of mission time. Subject to mission time, it can control the ability of accomplishing the mission at any time so as to ensure the high dependability. An example of water pump rotor relating to scheduled servicing is introduced to illustrate the failure rate refresh factor and the proposed maintenance strategy. Compared with traditional methods, the numerical results show that the failure rate refresh factor can describe the maintenance effect of servicing more intuitively and objectively. It also demonstrates that this maintenance strategy can prolong the lifetime, reduce the total lifetime maintenance cost and guarantee the dependability of system.

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

    International Nuclear Information System (INIS)

    Huang, C.-C.; Yuan, John

    2010-01-01

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

    2017-03-13

    To systematically review the available evidence on paediatric early warning systems (PEWS) for use in acute paediatric healthcare settings for the detection of, and timely response to, clinical deterioration in children. The electronic databases PubMed, MEDLINE, CINAHL, EMBASE and Cochrane were searched systematically from inception up to August 2016. Eligible studies had to refer to PEWS, inclusive of rapid response systems and teams. Outcomes had to be specific to the identification of and/or response to clinical deterioration in children (including neonates) in paediatric hospital settings (including emergency departments). 2 review authors independently completed the screening and selection process, the quality appraisal of the retrieved evidence and data extraction; with a third reviewer resolving any discrepancies, as required. Results were narratively synthesised. From a total screening of 2742 papers, 90 papers, of varied designs, were identified as eligible for inclusion in the review. Findings revealed that PEWS are extensively used internationally in paediatric inpatient hospital settings. However, robust empirical evidence on which PEWS is most effective was limited. The studies examined did however highlight some evidence of positive directional trends in improving clinical and process-based outcomes for clinically deteriorating children. Favourable outcomes were also identified for enhanced multidisciplinary team work, communication and confidence in recognising, reporting and making decisions about child clinical deterioration. Despite many studies reporting on the complexity and multifaceted nature of PEWS, no evidence was sourced which examined PEWS as a complex healthcare intervention. Future research needs to investigate PEWS as a complex multifaceted sociotechnical system that is embedded in a wider safety culture influenced by many organisational and human factors. PEWS should be embraced as a part of a larger multifaceted safety framework that

    Full Text Available Clinical deterioration (ICU transfer and cardiac arrest occurs during approximately 5-10% of hospital admissions. Existing prediction models have a high false positive rate, leading to multiple false alarms and alarm fatigue. We used routine vital signs and laboratory values obtained from the electronic medical record (EMR along with a machine learning algorithm called a neural network to develop a prediction model that would increase the predictive accuracy and decrease false alarm rates.Retrospective cohort study.The hematologic malignancy unit in an academic medical center in the United States.Adult patients admitted to the hematologic malignancy unit from 2009 to 2010.None.Vital signs and laboratory values were obtained from the electronic medical record system and then used as predictors (features. A neural network was used to build a model to predict clinical deterioration events (ICU transfer and cardiac arrest. The performance of the neural network model was compared to the VitalPac Early Warning Score (ViEWS. Five hundred sixty five consecutive total admissions were available with 43 admissions resulting in clinical deterioration. Using simulation, the neural network outperformed the ViEWS model with a positive predictive value of 82% compared to 24%, respectively.We developed and tested a neural network-based prediction model for clinical deterioration in patients hospitalized in the hematologic malignancy unit. Our neural network model outperformed an existing model, substantially increasing the positive predictive value, allowing the clinician to be confident in the alarm raised. This system can be readily implemented in a real-time fashion in existing EMR systems.

    ...The EPA is taking action to propose amendments to the New Source Review (NSR) Prevention of Significant Deterioration (PSD) program that would correct certain outdated language that currently limits EPA's ability to delegate the Federal PSD program to interested Indian tribes. This action proposes changes that would provide consistency with the current Federal PSD regulatory requirements by allowing the EPA to delegate the PSD program to interested tribes for their attainment areas. The regulations already authorize administrative delegation, and EPA has in the past delegated administration of the PSD program to states and local governments for their attainment areas. The EPA is proposing to delete a restriction on tribes' ability to take delegation of the PSD program and to include tribes, along with state and locals, in another section to make it clear that tribes may voluntarily take direct delegation of the NSR program in areas that are currently attaining the national ambient air quality standards (NAAQS). The rule would not impose any new requirements. The EPA is also proposing to correct a minor typographical error.

    2007-12-01

    Full Text Available Abstract Background Although there is no evidence that the long-term effects of scoliosis surgery are superior to the long-term effects of Adolescent Idiopathic Scoliosis (AIS itself, patients can fear the consequences of not under going this surgery due to incorrect or insufficient information. The main indication for surgical treatment in patients with AIS, is cosmetic. However spinal surgery may, along with other negative side effects, actually cause postoperative clinical deterioration. This complication of surgery has not yet been described in international literature. Case presentation A 15-year old female patient originally presenting with a well-compensated double curve pattern scoliosis. The patient was advised to undergo surgery due to the long-term negative impact of signs and symptoms of scoliosis upon her health. The patient agreed to surgery, which was performed in one of Germanys leading centres for spinal surgery. The thoracolumbar curve was corrected and fused, while the thoracic curve, clearly showing wedged vertebrae, defined as structural scoliosis, remained untreated. This operation left the patient with an unbalanced appearance, with radiological and clinical imbalance to the right. The clinical appearance of the patient though clearly deteriorated post-surgery. Furthermore, the wedged disc space below the fusion area indicates future problems with possible destabilisation accompanied probably by low back pain. Conclusion Scoliosis surgery for patients with AIS is mainly indicated for cosmetic or psychological reasons. Therefore the treatment leading to the best possible clinical appearance and balance has to be chosen. Patients should be informed that surgery will not necessarily improve their health status. Clinical deterioration after surgery may occur, and such information is crucial for an adequate informed consent.

    Imbalance between individual resources and work demands can lead to musculoskeletal disorders and reduced work ability. The purpose of this study was to investigate the effect of workplace- versus home-based physical exercise on work ability among healthcare workers. Two hundred female healthcare workers (Age: 42.0, BMI: 24.1, work ability index [WAI]: 43.1) from 18 departments at three Danish hospitals participated (Copenhagen, Denmark, Aug 2013-Jan 2014).

    In 2013, a National Early Warning System (EWS) was implemented in Ireland. Whilst evidence exists to support the clinical effectiveness of EWS in the acute health care setting, there is a paucity of information on their cost and cost effectiveness. The objective of this systematic literature review was to critically evaluate the economic literature on the use of EWS in adult patients in acute health care settings for the timely detection of physiological deterioration. A systematic literature review was conducted to accumulate the economic evidence on the use of EWS in adult patients in acute health care settings. The search yielded one health technology assessment, two budget impact analyses and two cost descriptions. Three of the studies were Irish, and considered the national EWS system. A Dutch study reported financial consequences of a single parameter EWS, as part of a rapid response system, in a surgical ward. The fifth study examined an advanced triage system in a medical emergency admission unit in Wales. The economic evidence on the use of EWS amongst adult patients in acute health care settings for the timely detection of physiological deterioration is limited. Further research is required to investigate the cost effectiveness of EWS, and the appropriateness of using standard methods to do so. The recent implementation of a national EWS in Ireland offers a unique opportunity to bridge this gap in the literature to examine the costs and cost effectiveness of a nationally implemented EWS system.

    Background. The epidemiological, social, and economic situation that surrounds the deterioration of skin integrity is a big problem for the health system. Its prevention and treatment create uncertainty and professional variability and it remains a priority to have good clinical practice guidelines (CPG). The objective was to determine the quality of the CPG on prevention and treatment of pressure ulcers (PU), venous ulcers of the leg (VUL) and diabetic foot ulcers (DFU). Methodology. Systematic review of the quality of Spanish and international CPG on PU, VUL and DFU. Bibliographic search in specialized sources. Selection of CPG, not older than 5 years (2010-2015). Use of the AGREE Instrument II and revision by 4 experts. Descriptive statistics. Results. Twenty-three CPG (10 PU, 6 VUL and 7 DFU), of which 4 were Spanish and 19 international. Eight CPG on PU, 3 VUL and 5 DFU were considered “Highly Recommended”. Domain nº 2 (participation) and Domain nº 5 (applicability) were the worst valued. The quality of the evidence was “very good” in 19 GPC. The best CPG were the British NICE (PU), the Australian AWMA (VUL) and the Canadian RNAO (DFU). Conclusions. We observed a good methodological quality in the CPG on PU and DFU, but there needs to be improvement in the VUL. In general, it would be necessary to increase the participation of users, and describe possible barriers for the implementation of the CPG in clinical practice.

    Given the increasing interest in demonstrating effectiveness in psychiatric treatment, the current paper seeks to advance outcome measurement in child psychiatry by demonstrating how more informative analytic strategies can be used to evaluate treatment in a real world setting using a brief, standardized parent-report measure. Questionnaires were obtained at intake for 1294 patients. Of these, 695 patients entered treatment and 531 (74%) had complete forms at intake and follow-up. Using this sample, we analyzed the data to determine effect sizes, rates of reliable improvement and deterioration, and rates of clinically significant improvement. Findings highlighted the utility of these approaches for evaluating treatment outcomes. Further suggestions for improving outcome measurement and evaluation are provided. © The Author(s) 2013.

    Machine learning methods are flexible prediction algorithms that may be more accurate than conventional regression. We compared the accuracy of different techniques for detecting clinical deterioration on the wards in a large, multicenter database. Observational cohort study. Five hospitals, from November 2008 until January 2013. Hospitalized ward patients None Demographic variables, laboratory values, and vital signs were utilized in a discrete-time survival analysis framework to predict the combined outcome of cardiac arrest, intensive care unit transfer, or death. Two logistic regression models (one using linear predictor terms and a second utilizing restricted cubic splines) were compared to several different machine learning methods. The models were derived in the first 60% of the data by date and then validated in the next 40%. For model derivation, each event time window was matched to a non-event window. All models were compared to each other and to the Modified Early Warning score, a commonly cited early warning score, using the area under the receiver operating characteristic curve (AUC). A total of 269,999 patients were admitted, and 424 cardiac arrests, 13,188 intensive care unit transfers, and 2,840 deaths occurred in the study. In the validation dataset, the random forest model was the most accurate model (AUC, 0.80 [95% CI, 0.80-0.80]). The logistic regression model with spline predictors was more accurate than the model utilizing linear predictors (AUC, 0.77 vs 0.74; p machine learning methods more accurately predicted clinical deterioration than logistic regression. Use of detection algorithms derived from these techniques may result in improved identification of critically ill patients on the wards.

    Full Text Available Economic production quantity (EPQ model has been analyzed for trended demand, and units in inventory are subject to constant rate. The system allows rework of imperfect units, and preventive maintenance time is random. A search method is used to study the model. The proposed methodology is validated by a numerical example. The sensitivity analysis is carried out to determine the critical model parameters. It is observed that the rate of change of demand, and the deterioration rate have a significant impact on the decision variables and the total cost of an inventory system. The model is highly sensitive to the production and demand rate.

    Early warning system (EWS) scores are used by hospital care teams to recognize early signs of clinical deterioration and trigger more intensive care. To systematically review the evidence on the ability of early warning system scores to predict a patient's risk of clinical deterioration and the impact of early warning system implementation on health outcomes and resource utilization. We searched the MEDLINE, CINAHL, and Cochrane Central Register of Controlled Trials databases through May 2014. We included English-language studies of early warning system scores used with adults admitted to medical or surgical wards. We abstracted study characteristics, including population, setting, sample size, duration, and criteria used for early warning system scoring. For predictive ability, the primary outcomes were modeled for discrimination on 48-hour mortality, cardiac arrest, or pulmonary arrest. Outcomes for the impact of early warning system implementation included 30-day mortality, cardiovascular events, use of vasopressors, respiratory failure, days on ventilator, and resource utilization. We assessed study quality using a modified Quality in Prognosis Studies assessment tool where applicable. Of 11,183 citations studies reviewed, one controlled trial and 20 observational studies of 13 unique models met our inclusion criteria. In eight studies, researchers addressed the predictive ability of early warning system tools and found a strong predictive value for death (area under the receiver operating characteristic curve [AUROC], 0.88-0.93) and cardiac arrest (AUROC, 0.74-0.86) within 48 hours. In 13 studies (one controlled trial and 12 pre-post observational studies), researchers addressed the impact on health outcomes and resource utilization and had mixed results. The one controlled trial was of good quality, and the researchers found no difference in mortality, transfers to the ICU, or length of hospital stay. The pre-post designs of the remaining studies have

    Full Text Available Introduction: Early identification of patients with unexpected clinical deterioration is a matter of serious concern. Previous studies have shown that early intervention on a patient whose health is deteriorating improves the patient outcome, and machine-learning-based approaches to predict clinical deterioration may contribute to precision improvement. To date, however, no systematic review in this area is available. Methods: We completed a search on PubMed on January 22, 2017 as well as a review of the articles identified by study authors involved in this area of research following the preferred reporting items for systematic reviews and meta-analyses (PRISMA guidelines for systematic reviews. Results: Twelve articles were selected for the current study from 273 articles initially obtained from the PubMed searches. Eleven of the 12 studies were retrospective studies, and no randomized controlled trials were performed. Although the artificial neural network techniques were the most frequently used and provided high precision and accuracy, we failed to identify articles that showed improvement in the patient outcome. Limitations were reported related to generalizability, complexity of models, and technical knowledge. Conclusions: This review shows that machine-learning approaches can improve prediction of clinical deterioration compared with traditional methods. However, these techniques will require further external validation before widespread clinical acceptance can be achieved.

    In recent studies, aminoguanidine (AG), an inhibitor of advanced glycation endproducts, has been identified as a prominent agent that can prevent the age-related aortic stiffening and cardiac hypertrophy. The aim of this study was to determine whether AG had effects on the left ventricular (LV)-arterial coupling in aged Fisher 344 rats in terms of the ventricular and arterial chamber properties. Normotensive rats were treated from 18 to 24 months with AG (1 g l(-1) in drinking water) and compared with a control group. LV pressure and ascending aortic flow signals were recorded to construct the ventricular and arterial end-systolic pressure-stroke volume relationships to calculate LV end-systolic elastance (Ees) and effective arterial volume elastance (Ea), respectively. The optimal afterload (Qload) determined by the ratio of Ea to Ees was used to measure the efficiency of mechanical energy transferred from the left ventricle to the arterial system. In comparison with the 6-month-old rats, the 24-month-old animals had decreased Ees, at 567.4 +/- 26.7 vs 639.0 +/- 20.7 mmHg ml(-1), decreased Ea, at 411.5 +/- 18.6 vs 577.9 +/- 15.7 mmHg ml(-1), and decreased Q(load), at 0.9428 +/- 0.0024 vs 0.9962 +/- 0.0014. Treatment with AG for 6 months did not significantly affect Ees; however, when normalized to LV weight (i.e., Eesn = Ees/LV weight), Eesn showed a significant rise of 22.8%, suggesting that AG may retard the aging process on the intrinsic contractility of the left ventricle. On the other hand, the decrease in Ea in aging rats was prevented by AG, as reflected in the increase of 19.7% in this variable (P < 0.05). The 24-month-old treated rats also exhibited a significant rise of 21.6% in Ea/Ees, causing an increase of 5.2% in Qload (P < 0.05). We conclude that in healthy older Fisher 344 rats without diabetes, long-term treatment with AG may improve both the arterial and ventricular function and optimize the matching condition for the left ventricular

    Full Text Available Juzentaihoto (JTT is a well-known Japanese herbal medicine, which has been reported to modulate immune responses and enhance antitumor immunity in animal models. However, it is not clear whether JTT has similar effects on humans. In particular, there is little information on the effects of JTT in antigen-specific immunity in cancer patients. Here we conducted a randomized clinical study to investigate whether combined usage of JTT could affect antigen-specific immunity and clinical findings in advanced pancreatic cancer patients undergoing personalized peptide vaccination (PPV, in which HLA-matched vaccine antigens were selected based on the preexisting host immunity. Fifty-seven patients were randomly assigned to receive PPV with (n=28 or without (n=29 JTT. Unexpectedly, JTT did not significantly affect cellular or humoral immune responses specific to the vaccine antigens, which were determined by antigen-specific interferon-γ secretion in T cells and antigen-specific IgG titers in plasma, respectively. Nevertheless, JTT prevented deterioration of patients’ conditions, such as anemia, lymphopenia, hypoalbuminemia, plasma IL-6 elevation, and reduction of performance status, which are frequently observed in advanced cancers. To our knowledge, this is the first clinical study that examined the immunological and clinical effects of JTT in cancer patients undergoing immunotherapy in humans.

    The capture of Federal regulatory agencies by the groups they were supposed to be regulating has been a topic of concern in the traditional literature of public administration. In his influential book The End of Liberalism, Professor Theordore Lowi suggested that capture resulted in part from vauge delegations of authority of Congress to regulatory agencies. Lowi argued that democracy would be better served if Congress were more specific in drafting laws, if agencies made greater use of formal rulemaking in implementing them, and if the courts rejected statutes which contained excessively vague delegations of authority - a remedy which he labeled juridicial democracy. This dissertation examines Lowi's theory in light of the experience of Congress and the Environmental Protection Agency (EPA) with the requirements of the Clean Air Act to prevent the significant deterioration of air quality in areas where air was already relatively clean. The history of the program to develop and carry out these requirements, known as PSD, is described in detail from its inception in the late 1960's through EPA's final regulations in 1980. Special attention is given to the actions taken by EPA after environmental groups successfully used the courts to force EPA to develop a PSD program in 1974, how Congress responded by amending the Clean Air Act in 1977, and the difficulties these amendments and subsequent additional court reviews caused for EPA.

    Imbalance between work demands and individual resources can lead to musculoskeletal disorders and reduced work ability. The aim of this study was to evaluate the effect of two contrasting interventions on work ability among slaughterhouse workers with chronic pain and work disability. Sixty-six slaughterhouse workers with upper-limb chronic pain and work disability were randomly allocated to 10 weeks of either strength training for the shoulder, arm, and hand muscles (3 times per week, 10 minutes per session) or ergonomic training (usual care control group) from September to December 2012. The outcome measure was the change from baseline to 10-week follow-up in the work ability index (WAI). A priori hypothesis testing showed a group×time interaction for WAI (Ptraining group, WAI increased 2.3 [95% confidence interval (95% CI) 0.9-3.7] in the strength training group corresponding to a moderate effect size (Cohen's d 0.52). Within-group changes indicated that between-group differences were mainly caused by a reduction in WAI in the ergonomic group. Of the 7 items of WAI, item 2 (work ability in relation to the demands of the job) and item 7 (mental resources) increased following strength training compared with ergonomic training (Ptraining at the workplace prevents deterioration of work ability among manual workers with chronic pain and disability exposed to forceful and repetitive job tasks. Thus, strength training performed at the workplace may in fact be regarded as a complex biopsychosocial intervention modality that reaches further than the specific physiological benefits of training per se.

    Arterial baroreflex control of muscle sympathetic nerve activity (ABRMSNA) is impaired in chronic systolic heart failure (CHF). The purpose of the study was to test the hypothesis that exercise training would improve the gain and reduce the time delay of ABRMSNA in CHF patients. Twenty-six CHF patients, New York Heart Association Functional Class II-III, EF ≤ 40%, peak V̇o2 ≤ 20 ml·kg(-1)·min(-1) were divided into two groups: untrained (UT, n = 13, 57 ± 3 years) and exercise trained (ET, n = 13, 49 ± 3 years). Muscle sympathetic nerve activity (MSNA) was directly recorded by microneurography technique. Arterial pressure was measured on a beat-to-beat basis. Time series of MSNA and systolic arterial pressure were analyzed by autoregressive spectral analysis. The gain and time delay of ABRMSNA was obtained by bivariate autoregressive analysis. Exercise training was performed on a cycle ergometer at moderate intensity, three 60-min sessions per week for 16 wk. Baseline MSNA, gain and time delay of ABRMSNA, and low frequency of MSNA (LFMSNA) to high-frequency ratio (HFMSNA) (LFMSNA/HFMSNA) were similar between groups. ET significantly decreased MSNA. MSNA was unchanged in the UT patients. The gain and time delay of ABRMSNA were unchanged in the ET patients. In contrast, the gain of ABRMSNA was significantly reduced [3.5 ± 0.7 vs. 1.8 ± 0.2, arbitrary units (au)/mmHg, P = 0.04] and the time delay of ABRMSNA was significantly increased (4.6 ± 0.8 vs. 7.9 ± 1.0 s, P = 0.05) in the UT patients. LFMSNA-to-HFMSNA ratio tended to be lower in the ET patients (P training prevents the deterioration of ABRMSNA in CHF patients. Copyright © 2015 the American Physiological Society.

    Annually 14.000 children with traumatic brain injury (TBI) are admitted to the Emergency Department (ED) in the Netherlands. Presentation varies and a specific entity comprises the juvenile head trauma syndrome (JHTS) with secondary deterioration after a mild trauma. As outcome of JHTS can be fatal, early recognition is essential. To outline the epidemiology and clinical features of JHTS, in comparison to paediatric mild TBI patients without JHTS. Retrospective study of 570 patients with mild TBI admitted to the ED of a level-one trauma centre from 2008 to 2014. Diagnosis of JHTS by experienced neurologists was compared with diagnosis by physicians at the ED. Physicians at the ED diagnosed JHTS more frequently (14%) compared to experienced neurologists (8%). JHTS occurred after a lucid interval varying from 5 to 225 min (mean 44 (SD 64)) with changes in consciousness. JHTS patients were younger compared to mild TBI patients (4.1 (SD 2.4) vs. 7.3 (SD 5.7), p syndrome comprise changes in consciousness and vomiting or changed behaviour on presentation at the ED. For clinical practice, these factors should guide the decision for hospital admission or discharge. Copyright © 2016 European Paediatric Neurology Society. Published by Elsevier Ltd.

  8. Use of Gypsum as a Preventive Measure for Strength Deterioration during Curing in Class F Fly Ash Geopolymer System

    Science.gov (United States)

    Jun, Yubin; Oh, Jae Eun

    2015-01-01

    This study discusses strength deterioration during the curing process of fly ash geopolymer and the use of CaSO4·2H2O (gypsum) as a deterioration remedy when the ash was synthesized using a 10M NaOH and Na-silicate solution. The strength decline was mainly due to the widespread formation of nanometer-sized cracks that were related to excessive Na and Si concentrations at an early age. Use of 2 wt% CaSO4·2H2O resulted in the best measured strength by temporarily reducing Na and Si concentrations; Na was absorbed by SO42−, up to 11% in the matrix within one day, and formed Na2SO4 (thenardite), which gradually dissolved over time, slowly releasing Na ions. However, more than 4% gypsum suppressed overall strength development because too many Na ions were locked into Na2SO4 and could not participate in geopolymerization. The addition of gypsum impeded glass dissolution and even halted the process when more than 4% gypsum was used.

    Tom Andrews, RN, B.Sc. (Hons, M.Sc., Ph.D.

    2005-03-01

    Full Text Available The research aims were to investigate the difficulties ward staff experienced in detecting deterioration and how these were resolved. The emphasis within the literature tends to be on identifying premonitory signs that may be useful in predicting deterioration. Changes in respiratory rate is the most consistent of these (Fieselmann et al. 1993; Sax and Charlson 1987; Schein et al. 1990; Smith and Wood 1998 but in common with other signs, it lacks sensitivity and specificity. The sample consisted of 44 nurses, doctors (Interns and health care support workers from a general medical and surgical ward. Data were collected by means of nonparticipant observations and interviews, using grounded theory as originated by (Glaser and Strauss 1967 and (Glaser 1978. As data were collected, the constant comparative method and theoretical sensitivity were used as outlined in grounded theory. A core category of “visualising deteriorating conditions” emerged, together with its sub-core categories of “intuitive knowing”, “baselining” and “grabbing attention”.The main concern in visualising deteriorating conditions is to ensure that patients suspected of deterioration are successfully referred to medical staff. The aim is to convince those who can treat or prevent further deterioration to intervene. Through intuitive knowing they pick up that patients have changed in a way that requires a medical assessment. To make the referral more credible, nurses attempt to contextualise any changes in patients by baselining (establishing baselines. Finally with the backup of colleagues, nurses refer patients by providing as much persuasive information as possible in a way that grabs attention.

    Full Text Available Background: The objective of this study was to describe the audiologic and related characteristics of a group patient with speech perception affected out of proportion to pure tone hearing loss. A case series of patient were referred for evaluation and management to the Hearing Research Center.To describe the clinical picture of the patients with the key clinical feature of hearing loss for pure tones and reduction in speech discrimination out of proportion to the pure tone loss, having some of the criteria of auditory neuropathy (i.e. normal otoacoustic emissions, OAE, and abnormal auditory brainstem evoked potentials, ABR and lacking others (e.g. present auditory reflexes. Methods: Hearing abilities were measured by Pure Tone Audiometry (PTA and Speech Discrimination Scores (SDS, measured in all patients using a standardized list of 25 monosyllabic Farsi words at MCL in quiet. Auditory pathway integrity was measured by using Auditory Brainstem Response (ABR and Otoacoustic Emission (OAE and anatomical lesions Computed Tomography Scan (CT and Magnetic Resonance Image (MRI of brain and retrocochlea. Patient included in the series were 35 patients who have SDS disproportionably low with regard to PTA, absent ABR waves and normal OAE. Results: All patients reported the beginning of their problem around adolescence. Neither of them had anatomical lesion in imaging studies and neither of them had any finding suggestive of conductive hearing lesion. Although in most of the cases the hearing loss had been more apparent in the lower frequencies (i.e. 1000 Hz and less, a stronger correlation was found between SDS and hearing threshold at higher frequencies. These patients may not benefit from hearing aids, as the outer hair cells are functional and amplification doesn’t seem to help; though, it was tried for all. Conclusion: These patients share a pattern of sensory –neural loss with no detectable lesion. The age of onset and the gradual

    Variable ventilation improves respiratory function, but it is not known whether the amount of variability in tidal volume (VT) can be reduced in recruited lungs without a deterioration of respiratory system elastance. Acute lung inflammation was induced by intratracheal instillation of lipopolysaccharide in 35 Wistar rats. Twenty-eight animals were anaesthetized and ventilated in volume-controlled mode. Lungs were recruited by random variation of VT (mean 6 ml kg(-1), coefficient of variation 30%, normal distribution) for 30 min. Animals were randomly assigned to different amounts of VT variability (n=7 for 90 min per group): 30, 15, 7.5, or 0%. Lung function, diffuse alveolar damage, and gene expression of biological markers associated with cell mechanical stress, inflammation, and fibrogenesis were assessed. Seven animals were not ventilated and served as controls for post-mortem analyses. A VT variability of 30%, but not 15, 7.5, or 0%, prevented deterioration of respiratory system elastance [Mean (SD) -7.5 (8.7%), Prespiratory system elastance and was not associated with lung histological damage. © The Author 2016.

  13. Worksite interventions for preventing physical deterioration among employees in job-groups with high physical work demands: Background, design and conceptual model of FINALE

    Directory of Open Access Journals (Sweden)

    Mortensen Ole S

    2010-03-01

    Full Text Available Abstract Background A mismatch between individual physical capacities and physical work demands enhance the risk for musculoskeletal disorders, poor work ability and sickness absence, termed physical deterioration. However, effective intervention strategies for preventing physical deterioration in job groups with high physical demands remains to be established. This paper describes the background, design and conceptual model of the FINALE programme, a framework for health promoting interventions at 4 Danish job groups (i.e. cleaners, health-care workers, construction workers and industrial workers characterized by high physical work demands, musculoskeletal disorders, poor work ability and sickness absence. Methods/Design A novel approach of the FINALE programme is that the interventions, i.e. 3 randomized controlled trials (RCT and 1 exploratory case-control study are tailored to the physical work demands, physical capacities and health profile of workers in each job-group. The RCT among cleaners, characterized by repetitive work tasks and musculoskeletal disorders, aims at making the cleaners less susceptible to musculoskeletal disorders by physical coordination training or cognitive behavioral theory based training (CBTr. Because health-care workers are reported to have high prevalence of overweight and heavy lifts, the aim of the RCT is long-term weight-loss by combined physical exercise training, CBTr and diet. Construction work, characterized by heavy lifting, pushing and pulling, the RCT aims at improving physical capacity and promoting musculoskeletal and cardiovascular health. At the industrial work-place characterized by repetitive work tasks, the intervention aims at reducing physical exertion and musculoskeletal disorders by combined physical exercise training, CBTr and participatory ergonomics. The overall aim of the FINALE programme is to improve the safety margin between individual resources (i.e. physical capacities, and

    The aim of this review is to provide a better base for predicting the ability of antioxidants to prevent lipid oxidation in food emulsions in general and in functional food systems enriched with n-3 PUFA in particular. Therefore, the antioxidant efficacies of a range of commercially available...... antioxidants in a number of fish oil enriched real food emulsions (milk, milk drink, salad dressing, mayonnaise and selected model emulsions) are compared. This comparison clearly shows that the same antioxidant exerts different effects in different systems. EDTA is a very efficient antioxidant in salad...

  16. Prevention of significant deterioration permit application for the Fueled Clad Fabrication System, the Radioisotope Power Systems Facility, and the Fuel Assembly Area

    Energy Technology Data Exchange (ETDEWEB)

    1989-08-01

    This New Source Review'' has been submitted by the US Department of Energy-Richland Operations Office (PO Box 550, Richland, Washington 99352), pursuant to WAC 173-403-050 and in compliance with the Department of Ecology Guide to Processing A Prevention Of Significant Deterioration (PSD) Permit'' for three new sources of radionuclide emissions at the Hanford Site in Washington State. The three new sources, the Fueled Clad Fabrication System (FCFS), the Radioisotope Power Systems Facility (RPSF), and the Fuel Assembly Area (FAA), will be located in one facility, the Fuels and Materials Examination Facility (FMEF) of the 400 Area. The FMEF was originally designed to provide for post-irradiation examination and fabrication of breeder reactor fuels. These FMEF missions were cancelled before the introduction of any fuel materials or any irradiated material. The current plans are to use the facility to fabricate power supplies for use in space applications and to produce Fast Flux Test Facility (FFTF) fuel and target assemblies. The FCFS and the RPSF will produce materials and assemblies for application in space. The FAA project will produce FFTF fuel and target assemblies. The FCFS and the RPSF will share the same building, stack, and, in certain cases, the same floor space. Given this relationship, these systems will be dealt with separately to the extent possible. The FAA is a comparatively independent operation though it will share the FMEF complex.

    A study was performed to determine the potential influence of a rapid response system (RRS) employing real-time clinical deterioration alerts (RTCDAs) on patient outcomes involving 8 general medicine units. Introduction of the RRS occurred in 2006 with staged addition of the RTCDAs in 2009. Statistically significant year-to-year decreases in mortality were observed through 2014 ( r = -.794; P = .002). Similarly, year-to-year decreases in the number of cardiopulmonary arrests (CPAs; r = -.792; P = .006) and median lengths of stay ( r = -.841; P = .001) were observed. There was a statistically significant year-to-year increase in the number of RRS activations for these units ( r = .939; P < .001) that was inversely correlated with the occurrence of CPAs ( r = -.784; P = .007). In this single-institution retrospective study, introduction of a RRS employing RTCDAs was associated with lower hospital mortality, CPAs, and hospital length of stay.

  2. Ultraviolet Keratitis: From the Pathophysiological Basis to Prevention and Clinical Management.

    Science.gov (United States)

    Willmann, Gabriel

    2015-12-01

    Ultraviolet keratitis is caused by the toxic effects of acute high-dose ultraviolet radiation (UVR) reflecting the sensitivity of the ocular surface to photochemical injury. The clinical syndrome presents with ocular pain, tearing, conjunctival chemosis, blepharospasm, and deterioration of vision typically several hours after exposure, lasting up to 3 days. Mountaineers, skiers, and beach recreationalists are particularly at risk to suffer from ultraviolet (UV) keratitis as the reflectivity of UVR in these environments is extremely high. The aim of this review is to raise awareness about the potential of UV damage on the eye with an emphasis on UV keratitis, to highlight the pathophysiological basis of corneal phototoxicity, and to provide practical guidance for the prevention and clinical management of UV keratitis commonly known as snow blindness.

  3. Prevention of epilepsy: Should we be avoiding clinical trials?

    Science.gov (United States)

    Klein, Pavel; Tyrlikova, Ivana

    2017-07-01

    Epilepsy prevention is one of the great unmet needs in epilepsy. Approximately 15% of all epilepsy is caused by an acute acquired CNS insult such as traumatic brain injury (TBI), stroke or encephalitis. There is a latent period between the insult and epilepsy onset that presents an opportunity to intervene with preventive treatment that is unique in neurology. Yet no phase 3 epilepsy prevention studies, and only 2 phase 2 studies have been initiated in the last 16years. Current prevailing opinion is that the research community is not ready for clinical preventive epilepsy studies, and that animal models should first be refined and biomarkers of epileptogenesis and of epilepsy discovered before clinical studies are embarked upon. We review data to suggest that there is basis to do epilepsy prevention studies now with the current knowledge and available drugs, and that those studies are feasible with currently available tools. We suggest that a different approach is needed from the past in order to maximize chances of success, minimize the cost, and set up platform for future preventive treatment development. That approach should include close coordination of preclinical and clinical development programs in a combined PTE prevention strategy, consideration of polytherapy, and simultaneous, combined clinical development of preventive treatment and of biomarker discovery. We argue that the currently favored approach of eschewing clinical studies until biomarkers are available will delay the discovery of epilepsy prevention treatment by at least 10 years and significantly increase the cost of such discovery.

  5. Under Persistent Assault: Understanding the Factors that Deteriorate Human Skin and Clinical Efficacy of Topical Antioxidants in Treating Aging Skin

    Directory of Open Access Journals (Sweden)

    Patricia K. Farris

    2015-11-01

    Full Text Available Recent studies contend that the skin is subject to far more damage than just ultraviolet (UV light, with infrared radiation and pollution now clearly demonstrated to degrade cutaneous tissue. While consumers continue to strive for new ways to augment the aesthetic appeal and improve the health of their skin, awareness regarding environmental insults and effective ways to protect the skin remains low. New advances in dermatologic science have exponentially increased the available information on the underlying mechanism of cutaneous damage and potential of topical antioxidants to treat aging skin. Combining antioxidants that can work through multiple pathways holds great potential for a cumulative and synergistic way to treat aging skin. Our goal is to provide a comprehensive review on environmental factors that damage human skin, discuss scientifically proven benefits of topical antioxidants, understand challenges of formulating and administering topical antioxidants, evaluate novel mechanisms of antioxidant activity, and suggest practical ways of integrating topical antioxidants with aesthetic procedures to complement clinical outcomes.

    2016-03-01

    Alzheimer's disease (AD) is a major source of morbidity and mortality, with the disease burden expected to rise as the population ages. No disease-modifying agent is currently available, but recent research suggests that nutritional and lifestyle modifications can delay or prevent the onset of AD. However, preventive nutritional interventions are not universally applicable and depend on the clinical profile of the individual patient. This article reviews existing nutritional modalities for AD prevention that act through improvement of insulin resistance, correction of dyslipidemia, and reduction of oxidative stress, and discusses how they may be modified on the basis of individual biomarkers, genetics, and behavior. In addition, we report preliminary results of clinical application of these personalized interventions at the first AD prevention clinic in the United States. The use of these personalized interventions represents an important application of precision medicine techniques for the prevention of AD that can be adopted by clinicians across disciplines. © 2016 New York Academy of Sciences.

  7. Patient-Reported Outcomes Assessed by the CAMPHOR Questionnaire Predict Clinical Deterioration in Idiopathic Pulmonary Arterial Hypertension and Chronic Thromboembolic Pulmonary Hypertension

    McCabe, Colm; Bennett, Maxine; Doughty, Natalie; MacKenzie Ross, Robert; Sharples, Linda

    2013-01-01

    Background: The Cambridge Pulmonary Hypertension Outcome Review (CAMPHOR) is a disease-specific assessment tool used for the evaluation and follow-up of patients with pulmonary hypertension (PH). We describe a novel use for this questionnaire in its potential to predict clinical deterioration (CD) in two patient cohorts with subtypes of PH, idiopathic pulmonary arterial hypertension (IPAH), and chronic thromboembolic pulmonary hypertension (CTEPH) during an 8-year period. Methods: We retrospectively analyzed CAMPHOR scores obtained at baseline and at follow-up visits in patients under the care of our unit over an 8-year period to assess CD and survival, as well as 6-min walk distance (6MWD) and New York Heart Association (NYHA) class. Results: Using Cox regression, we demonstrated a significant predictive effect of CD from total CAMPHOR scores at study enrollment in IPAH and CTEPH (hazard ratios, 1.03 [95% CI, 1.01-1.05] and 1.04 [95% CI, 1.02-1.06] per unit score increase, respectively), as well as from CAMPHOR subscales as independent predictors. This predictive effect is diluted after adjusting for the prognostic effect of 6MWD and NYHA class. Repeated CAMPHOR assessment over time appears not to add predictive value of CD to that obtained at diagnosis, although it still informs physicians of important changes in self-reported symptoms. Conclusions: When emphasis is placed on the evaluation of patient perceptions, CAMPHOR may represent an alternative method of estimating the likelihood of CD. PMID:23430021

  8. A framework for chiropractic training in clinical preventive services.

    Science.gov (United States)

    Hawk, Cheryl; Evans, Marion Willard

    2013-08-20

    The 2010 Patient Protection and Affordable Care Act provides incentives for both patients and providers to engage in evidence-based clinical preventive services recommended by the United States Preventive Services Task Force (USPSTF). Depending upon the application of the new health care act, Doctors of Chiropractic (DC) may be considered to be covered providers of many of these services. It is therefore essential that DCs' training prepare them to competently deliver them. The aim of this commentary is to describe a framework for training in clinical preventive services, based largely on the USPSTF recommendations, which could be readily integrated into existing DC educational programs.

  4. Differentiating clinical care from disease prevention: a prerequisite for practicing quaternary prevention

    Directory of Open Access Journals (Sweden)

    Charles Dalcanale Tesser

    Full Text Available Abstract: This article contends that the distinction between clinical care (illness and prevention of future disease is essential to the practice of quaternary prevention. The authors argue that the ongoing entanglement of clinical care and prevention transforms healthy into "sick" people through changes in disease classification criteria and/or cut-off points for defining high-risk states. This diverts health care resources away from those in need of care and increases the risk of iatrogenic harm in healthy people. The distinction in focus is based on: (a management of uncertainty (more flexible when caring for ill persons; (b guarantee of benefit (required only in prevention; (c harm tolerance (nil or minimal in prevention. This implies attitudinal differences in the decision-making process: greater skepticism, scientism and resistance towards preventive action. These should be based on high-quality scientific evidence of end-outcomes that displays a net positive harm/benefit ratio.

  7. FRED: Exergame to Prevent Dependence and Functional Deterioration Associated with Ageing. A Pilot Three-Week Randomized Controlled Clinical Trial

    Directory of Open Access Journals (Sweden)

    Iranzu Mugueta-Aguinaga

    2017-11-01

    Full Text Available Introduction: Frailty syndrome and advanced age may decrease the acceptance of illness and quality of life, and worsen patients’ existing health conditions, as well as leading to an increase in health care expenses. Purpose: The purpose of this study is to reduce frailty risk via the use of a FRED game which has been expressly designed and put together for the study. Materials and methods: A total of 40 frail volunteers with a score of <10 points in the short physical performance battery (SPPB took part in a feasibility study in order to validate the FRED game. Following randomisation, the study group (20 subjects took part in nine sessions of 20 min each over a three-week period. The control group (19 subjects continued to lead their daily lives in the course of which they had no physical activity scheduled; Results: After three weeks and having taken part in nine physical activity sessions with the FRED game, 60% of subjects from the study group (12/20 obtained a score of ≥10 points at the end of the study, i.e., less risk of evidencing frailty. This result proved to be statistically significant (p < 0.001. The degree of compliance with and adherence to the game was confirmed by 100% attendance of the sessions. Discussion: Our findings support the hypothesis that FRED, an ad hoc designed exergame, significantly reduced the presence and severity of frailty in a sample of sedentary elders, thus potentially modifying their risk profile. Conclusions: The FRED game is a tool that shows a 99% certain improvement in the degree of frailty in frail elderly subjects. The effectiveness of the design of ad hoc games in a certain pathology or population group is therefore evidenced.

  8. Clinical Trial Design for HIV Prevention Research: Determining Standards of Prevention.

    Dawson, Liza; Zwerski, Sheryl

    2015-06-01

    This article seeks to advance ethical dialogue on choosing standards of prevention in clinical trials testing improved biomedical prevention methods for HIV. The stakes in this area of research are high, given the continued high rates of infection in many countries and the budget limitations that have constrained efforts to expand treatment for all who are currently HIV-infected. New prevention methods are still needed; at the same time, some existing prevention and treatment interventions have been proven effective but are not yet widely available in the countries where they most urgently needed. The ethical tensions in this field of clinical research are well known and have been the subject of extensive debate. There is no single clinical trial design that can optimize all the ethically important goals and commitments involved in research. Several recent articles have described the current ethical difficulties in designing HIV prevention trials, especially in resource limited settings; however, there is no consensus on how to handle clinical trial design decisions, and existing international ethical guidelines offer conflicting advice. This article acknowledges these deep ethical dilemmas and moves beyond a simple descriptive approach to advance an organized method for considering what clinical trial designs will be ethically acceptable for HIV prevention trials, balancing the relevant criteria and providing justification for specific design decisions.

    Assessment of kidney function evolution after {sup 90}Y-DOTATOC peptide receptor radionuclide therapy (PRRT) with capped activity administration based on a 37-Gy threshold of biological effective dose (BED) to the kidney. In a prospective phase II study, patients with metastasized neuroendocrine tumours were evaluated for therapy using 185 MBq {sup 111}In-pentetreotide with amino acid coinfusion. Planar whole-body images were acquired at four time-points after injection and kidney volumes were measured using CT/MRI. BED to the kidneys was estimated using an extended BED formula and biexponential renal clearance. Based on published BED dose-toxicity relationships, we allowed a maximal kidney BED of 37 Gy; if the calculated BED exceeded 37 Gy, treatment activity was reduced accordingly. Kidney function was assessed at baseline and at 18 months, predominantly using {sup 51}Cr-EDTA. The rate of renal function decline was expressed as annual glomerular filtration rate loss (aGFRL). Only 22 of 50 patients reached the 18-months time-point, with most missing patients having died due to disease progression. In the 22 patients who reached 18 months, no rapid kidney function deterioration was observed over the 18 months, aGFRL >33 % was not seen, and only three patients showed an increase of one toxicity grade and one patient an increase of two grades. No significant correlations between kidney volume (p = 0.35), baseline GFR (p = 0.18), risk factors for renal function loss (p = 0.74) and aGFRL were observed. Among the 28 patients who did not reach 18 months, one developed grade 4 kidney toxicity at 15 months after PRRT. Prospective dosimetry using a 37 Gy BED as the threshold for kidney toxicity is a good guide for {sup 90}Y-DOTATOC PRRT and is associated with a low risk of rapid renal function deterioration and evolution to severe nephrotoxicity.

    Cytomegalovirus is the most common congenital infection causing serious disease in infants. It is the leading infectious cause of sensorineural hearing loss and neurodevelopmental disability in developed countries. Despite the clinical importance of congenital cytomegalovirus, surveys show there is limited awareness and knowledge in the medical and general community about congenital cytomegalovirus infection. This article reviews the clinical features, global epidemiology, transmission and risk factors for cytomegalovirus infections. It also highlights several major advances made in recent years in the diagnosis and prevention of cytomegalovirus infection during pregnancy. Although research is ongoing, no therapy is currently proven to prevent or treat maternal, fetal or neonatal cytomegalovirus infection. Education of women regarding hygiene measures can help prevent cytomegalovirus infection and are currently the best strategy to prevent congenital cytomegalovirus disease.

    Health-related quality of life (HRQOL) measures have become the mainstay for outcome appraisal in spine surgery. Clinically meaningful interpretation of HRQOL improvement has centered on the minimum clinically important difference (MCID). The purpose of this study was to calculate clinically important deterioration (CIDET) thresholds and determine a CIDET value for each HRQOL measure for patients undergoing lumbar fusion. Seven hundred twenty-two patients (248 males, 127 smokers, mean age 60.8 years) were identified with complete preoperative and 1-year postoperative HRQOLs including the Oswestry Disability Index (ODI), 36-Item Short Form Health Survey (SF-36), and numeric rating scales (0-10) for back and leg pain following primary, instrumented, posterior lumbar fusion. Anchor-based and distribution-based methods were used to calculate CIDET for each HRQOL. Anchor-based methods included change score, change difference, and receiver operating characteristic curve analysis. The Health Transition Item, an independent item of the SF-36, was used as the external anchor. Patients who responded "somewhat worse" and "much worse" were combined and compared with patients responding "about the same." Distribution-based methods were minimum detectable change and effect size. Diagnoses included spondylolisthesis (n = 332), scoliosis (n = 54), instability (n = 37), disc pathology (n = 146), and stenosis (n = 153). There was a statistically significant change (p < 0.0001) for each HRQOL measure from preoperatively to 1-year postoperatively. Only 107 patients (15%) reported being "somewhat worse" (n = 81) or "much worse" (n = 26). Calculation methods yielded a range of CIDET values for ODI (0.17-9.06), SF-36 physical component summary (-0.32 to 4.43), back pain (0.02-1.50), and leg pain (0.02-1.50). A threshold for clinical deterioration was difficult to identify. This may be due to the small number of patients reporting being worse after surgery and the variability across

    At first, a hardness of a minute region and an elongation at break are measured relative to a plurality of reference samples having deterioration which is different stepwise, to obtain a relation between the hardness of the minute region and the elongation at break. They are obtained as information of correlation showing the degree of deterioration of cables. Then, samples are collected. The samples are collected from a PVC sheath. In this case, the samples to be used for the measurement are extremely small piece having the size of one side of about several hundred μm. Then, the hardness of the minute region of the samples is measured. The measured hardness of the minute region is corresponded to the previously obtained information of the correlation for deteriorations to judge the state of deterioration for the collected samples. With such procedures, the state of deterioration for electric wires and cables to be used in nuclear facilities such as power plants can easily be diagnosed substantially non destructively. (I.N.)

    The dramatic increase in breast cancer incidence compels a paradigm shift in our preventive efforts. There are several barriers to overcome before prevention becomes an established part of breast cancer management. The objective of this review is to identify the clinical challenges for improved breast cancer prevention and discuss current knowledge on breast cancer risk assessment methods, risk communication, ethics, and interventional efforts with the aim of covering the aspects relevant for a breast cancer prevention trial. Herein, the following five areas are discussed: (i) Adequate tools for identification of women at high risk of breast cancer suggestively entitled Prevent! Online. (ii) Consensus on the definition of high risk, which is regarded as mandatory for all risk communication and potential prophylactic interventions. (iii) Risk perception and communication regarding risk information. (iv) Potential ethical concerns relevant for future breast cancer prevention programs. (v) Risk-reducing programs involving multileveled prevention depending on identified risk. Taken together, devoted efforts from both policy makers and health care providers are warranted to improve risk assessment and risk counseling in women at risk for breast cancer to optimize the prevention of breast cancer.

A 58-year-old man underwent ethmoid sinus surgery and subsequently developed rapidly progressive global headache, restlessness, diplegia with sensory loss, and deterioration of the conscious level. A head CT demonstrated extensive pneumocephalus with gross compression of the brain. The frontal retention of air caused widening of the interhemispheric fissure leading to a peaked appearance of the frontal poles, referred to as the ‘Mount Fuji sign’. Surgical revision of a dural air leak resulted in rapid improvement and full clinical resolution. Early diagnosis of tension pneumocephalus and emergent surgical treatment are crucial to prevent life-threatening deterioration.

    Protection of neurons from degeneration is an important preventive strategy for dementia. Much of the dementia pathology implicates oxidative stress pathways. Turmeric (Curcuma longa L.) contains curcuminoids which has anti-oxidative and neuro-protective effects. These effects are considered to be similar to those of citicoline which has been regularly used as one of standard medications for dementia. This study aimed at investigating the effects of turmeric rhizome extract on the hippocampus of trimethyltin (TMT)-treated Sprague-Dawley rats. The rats were divided randomly into six groups, i.e., a normal control group (N); Sn group, which was given TMT chloride; Sn-Cit group, which was treated with citicoline and TMT chloride; and three Sn-TE groups, which were treated with three different dosages of turmeric rhizome extract and TMT chloride. Morris water maze test was carried out to examine the spatial memory. The estimated total number of CA1 and CA2-CA3 pyramidal cells was calculated using a stereological method. The administration of turmeric extract at a dose of 200 mg/kg bw has been shown to prevent the deficits in the spatial memory performance and partially inhibit the reduction of the number of CA2-CA3 regions pyramidal neurons. TMT-induced neurotoxic damage seemed to be mediated by the generation of reactive oxygen species and reactive nitrogen species. Turmeric extract might act as anti inflammatory as well as anti-oxidant agent. The effects of turmeric extract at a dose of 200 mg/kg bw seem to be comparable to those of citicoline.

    The caries prevention by using laser irradiation has been investigated during the last 30 years. The Nd: YAG laser associated with acidulated phosphate fluoride has been shown as a very promising technique for enamel caries prevention. The aim of this work was to clinically evaluate the efficiency of Nd: YAG laser associated with acidulated phosphate fluoride in pit and fissure caries prevention of children and adolescents. In this work it was determined the dye that enhance the effect of Nd: YAG laser in enamel. It was selected 242 pre-molar and molar teeth from 33 children and adolescents, aged from 7 to 15 years old. The selected teeth were free from caries or decalcification marks (active white marks) to the clinical and radiographic exams. The teeth were divided into two groups: the first group was laser irradiated and their homologous remained as a control. The right side teeth were dye-assisted Nd:YAG laser irradiated. The dye solution was a moisture of dust coal and equal parts of water and alcohol. The irradiation conditions were 60 mJ/10 Hz, optical fiber in contact mode, with diameter of 300 μm, resulting in an energy density of 84,9 J/cm 2 . The oclusal surface of the teeth was completely irradiated, specially on the slopes and in the deepest part of the pits and fissures. This procedure was repeated three times. In the sequence it was applied the acidulated phosphate fluoride for 4 minutes. On the left side teeth - control group- only acidulated phosphate fluoride was applied for the same time. The final examination considered the presence of caries and active white marks after a period of one year. There were statistical significant differences (p < 0.01) between the lased + fluoride group and the non irradiated group. The present study concluded that the technique used in this work can be an alternative clinical method for caries prevention. (author)

    The emergence of advanced genetic technologies raises many challenges for dementia care and the conduct of related social, behavioural and clinical research. Genetic tests are already used to identify possible participants in dementia prevention trials. These tests are unlike any other in clinical medicine as they have the capacity to predict disease onset after intervals of many years with implications for other family members. Genetic counselling professionals support services in paediatrics, cancer diagnosis and some adult-onset diseases. Their capacity cannot meet the needs for pre- and post-test support of the many "at-risk" families living with late onset dementia. Most dementias are common, complex conditions in which multiple genetic and environmental factors play important and potentially modifiable roles. Large scale prevention studies are needed to test the effectiveness of interventions. Some economy of effort will be achieved by the preferential inclusion of "at-risk" families. Many such families are in contact with dementia care services and will be motivated to participate in prevention studies. However, practice standards and consensus-based guidelines do not yet exist. Support services are not available on a scale sufficient to prevent harm when risk is poorly communicated causing unnecessary psychological morbidity in unaffected family members. There is a pressing need for research to inform the development of study guidelines and to identify how services are strengthened to support these families during and after their participation in trials. Discourse analysis provides a useful method to collect and analyse data of this type and supports the conclusions of this review. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    During the past two decades PCR and several other DNA/RNA amplification techniques have become important diagnostic tools in clinical laboratories. Amplification products contamination has been the main impediment to using these techniques routinely in diagnostic laboratories. Over the years, several creative pre- and post-amplification methods have been developed that prevent amplicon carryover contamination. These procedures, coupled with automated systems that employ real-time amplification and simultaneous detection in a closed system, have substantially reduced the possibility of false positive results due to amplification products carryover contamination.

    Full Text Available Antecedentes: En los últimos años han aparecido diversas intervenciones no farmacológicas destinadas a prevenir el deterioro cognitivo asociado a la edad, concretamente los problemas de memoria, cuya efectividad no ha sido suficientemente evaluada. Objetivo: Establecer la efectividad de las intervenciones cognitivas en la prevención del deterioro de la memoria asociado a la edad mediante una revisión de la literatura científica. Métodos: Se realizó una búsqueda exhaustiva en PubMed. Se incluyeron los estudios publicados desde 1990 que evaluaran la efectividad de una intervención cognitiva sobre la memoria en personas mayores sin deterioro cognitivo leve ni demencia, y se clasificaron según su calidad. Se evaluaron los efectos, a corto y a largo plazo, sobre el rendimiento en tareas de memoria objetiva y subjetiva y la transferencia a otros dominios cognitivos. Resultados: Veinticinco estudios cumplieron los criterios de inclusión. Once (44% fueron considerados de elevada calidad, de los cuales todos excepto uno mejoraron algún indicador de memoria. El tipo de memoria más evaluada fue la memoria objetiva reciente verbal, que mejoró en 8 de 9 de los estudios de elevada calidad. La memoria objetiva reciente no verbal y de asociación, evaluadas principalmente por los estudios de calidad media, mejoraron en 4 de 7, y en 10 de 11 estudios, respectivamente. Los resultados referentes a memoria subjetiva fueron muy heterogéneos. La transferencia únicamente se observó en uno de 7 estudios de elevada calidad. Conclusiones: Los resultados sugieren que determinadas intervenciones cognitivas desarrolladas en personas mayores sanas son efectivas en la prevención del deterioro de la memoria, especialmente sobre la memoria reciente verbal.Background: In the last few years, several non-pharmacological interventions have been developed to prevent age-associated cognitive deterioration, specifically memory deterioration.

    Improving access to preventive care requires addressing patient, provider, and systems barriers. Patients often lack knowledge or are skeptical about the importance of prevention. Physicians feel that they have too little time, are not trained to deliver preventive services, and are concerned about the effectiveness of prevention. We have implemented an educational module in the required family practice clerkship (1) to enhance medical student learning about common clinical preventive services and (2) to teach students how to inform and involve patients in shared decision making about those services. Students are asked to examine available evidence-based information for preventive screening services. They are encouraged to look at the recommendations of various organizations and use such resources as reports from the U.S. Preventive Services Task Force to determine recommendations they want to be knowledgeable about in talking with their patients. For learning shared decision making, students are trained to use a model adapted from Braddock and colleagues(1) to discuss specific screening services and to engage patients in the process of making informed decisions about what is best for their own health. The shared decision making is presented and modeled by faculty, discussed in small groups, and students practice using Web-based cases and simulations. The students are evaluated using formative and summative performance-based assessments as they interact with simulated patients about (1) screening for high blood cholesterol and other lipid abnormalities, (2) screening for colorectal cancer, (3) screening for prostate cancer, and (4) screening for breast cancer. The final student evaluation is a ten-minute, videotaped discussion with a simulated patient about screening for colorectal cancer that is graded against a checklist that focuses primarily on the elements of shared decision making. Our medical students appear quite willing to accept shared decision making as

    Full Text Available AIM: To analyze the clinical features of children ocular penetrating trauma, and hope to effectively assist to prevent pediatric ocular traumaMETHODS: The data of 145 cases(145 eyeswith ocular penetrating trauma, hospitalized in Xijing Hospital from January 2012 to December 2016, were collected and retrospectively analyzed. All the data of injury factors and environment, age and gender of patients, lesions, treatment and prognosis were detailed studied.RESULTS: In all the 145 pediatric patients with ocular penetrating trauma, accounted for 8.5% of all the ocular trauma patients, there were 95 cases of male, and 50 of female. Penetrating injuries mainly occurred in age of 3-9. The main injuries of ocular perforating in children were scissors, and sharp objects of wooden and iron. The wound was often located in the cornea or the anterior sclera. Traumatic cataract, vitreous hemorrhage and endophthalmitis were the common complications. The visual acuity was severely damaged, and 90 cases(62.1%of the children recovered better than 0.1 after effective treatment.CONCLUSION: The visual function of pediatric p0atients was seriously threatened after penetrating injuries. However, the damage of vision and the rate of blindness can be reduced effectively after timely and correct diagnosis and treatment. It is the most important that active and effective prevention in keep children away from penetrating injuries.

    Full Text Available In this study, we have analyzed the influence of hydronephrosis upon the microcirculation system, in situations of pyeloureteral junction obstruction. Herein, bulbar conjunctiva has been chosen as the object of this biomicroscopic study because of its simplicity and the method availability in clinic practice. In fulfilling this work, we ascertained the connections between extravascular, intravascular, vascular and general conjunctival indices of the patients before radical and paliatic correction of the pyeloureteral junction obstruction (i.e. by open and laparoscopic pyeloplasty, endopyelotomy, laser resection and balloon dilatation. We concluded that, apart from the proved deterioration of kidney function, systemic deteriorations of microcirculation may be observed in situations of clinically marked hydronephrosis, according to the results of radioisotope renography and excretory urography.

    Orbital emphysema is usually considered as self-limiting condition, rarely carries a risk of vision loss as catastrophic consequences due to occlusion of the central retinal artery. It can occur as a consequence of head trauma associated with fracture of the orbit, previous surgery, infection or exposure to high-pressure air jet. Authors report an interesting 7-year-old girl who presented with proptosis of left eye, associated with swelling of eyelids of both eyes. Computerized tomography scan head and orbit revealed orbital emphysema in the left eye with fracture of medial wall of left orbit and fracture of orbit roof with small pneumocephalus over left basifrontal region. Fortunately, she responded well to conservative therapy. Current article reminds uncommon condition to prevent potential visual loss, describing briefly management options.

    We describe a case of acute functional deterioration in a 13-year-old girl with severe spastic diplegia (GMFCS III) and a new diagnosis of diffuse intrinsic pontine glioma (DIPG). She presented with acute deterioration in mobility and motor function over 1 month, which was associated with dysarthria, dysphagia and behavioural change. Her mother had noticed subtle functional deterioration over the 2 months prior to this. Her physiotherapist who was concerned about her acute functional deterioration referred her for emergency review. Neurological imaging revealed a diffuse pontine lesion consistent with DIPG. She was subsequently referred to oncology. She deteriorated further, clinically, over the next few days and following discussion with the team; her family opted for palliative treatment, given the poor prognosis associated with DIPG.

To stop this increase in asthma, causes and prevention measures should be known better. For the management of the illness, control of environmental and trigger factors causing asthma attack are extremely important. Asthmatic children and family should be informed by health staff about changes in their life and measures to prevent the attacks. Through this information asthmatic children and their families can be supported for a better quality of life. [TAF Prev Med Bull 2010; 9(1.000: 79-86

    Background Low back pain (LBP) is a prevalent condition and a socioeconomic problem in many countries. Due to its recurrent nature, the prevention of further episodes (secondary prevention), seems logical. Furthermore, when the condition is persistent, the minimization of symptoms and prevention of deterioration (tertiary prevention), is equally important. Research has largely focused on treatment methods for symptomatic episodes, and little is known about preventive treatment strategies. Met...

    This paper examines the role of clinical practitioners and clinical researchers internationally in establishing the utility of harm-reduction approaches to substance use. It thus illustrates the potential for clinicians to play a pivotal role in health promoting structural interventions based on harm-reduction goals and public health models. Popular media images of drug use as uniformly damaging, and abstinence as the only acceptable goal of treatment, threaten to distort clinical care away from a basis in evidence, which shows that some ways of using drugs are far more harmful than others and that punitive approaches and insistence on total abstinence as the only goal of treatment often increases the harms of drug use rather than reducing drug use. Therefore the leadership and scientific authority of clinicians who understand the health impact of harm-reduction strategies is needed. Through a review of harm-reduction interventions in Canada, the United Kingdom, the United States, Australia, Switzerland, and the Netherlands, we identify three ways that clinicians have helped to achieve a paradigm shift from punitive approaches to harm-reduction principles in clinical care and in drug policy: (1) through clinical research to provide data establishing the effectiveness and feasibility of harm-reduction approaches, (2) by developing innovative clinical programmes that employ harm reduction, and thereby (3) changing the standard of care to include routine use of these evidence-based (but often misunderstood) approaches in their practices. We argue that through promotion of harm-reduction goals and methods, clinicians have unique opportunities to improve the health outcomes of vulnerable populations.

    In 2008, the UK National Osteoporosis Guideline Group (NOGG) produced a guideline on the prevention and treatment of osteoporosis, with an update in 2013. This paper presents a major update of the guideline, the scope of which is to review the assessment and management of osteoporosis and the prevention of fragility fractures in postmenopausal women and men age 50 years or over. Where available, systematic reviews, meta-analyses and randomised controlled trials were used to provide the evidence base. Conclusions and recommendations were systematically graded according to the strength of the available evidence. Review of the evidence and recommendations are provided for the diagnosis of osteoporosis, fracture-risk assessment, lifestyle measures and pharmacological interventions, duration and monitoring of bisphosphonate therapy, glucocorticoid-induced osteoporosis, osteoporosis in men, postfracture care and intervention thresholds. The guideline, which has received accreditation from the National Institute of Health and Care Excellence (NICE), provides a comprehensive overview of the assessment and management of osteoporosis for all healthcare professionals who are involved in its management.

  19. Preventing medico-legal issues in clinical practice

    Directory of Open Access Journals (Sweden)

    Bevinahalli N Raveesh

    2016-01-01

    Full Text Available The medical profession is considered to be one of the noblest professions in the world. The practice of medicine is capable of rendering noble service to humanity provided due care, sincerity, efficiency, and professional skill is observed by the doctors. However, today, the patient–doctor relationship has almost diminished its fiduciary character and has become more formal and structured. Doctors are no longer regarded as infallible and beyond questioning. Corporatization of health care has made it like any other business, and the medical profession is increasingly being guided by the profit motive rather than that of service. On the other hand, a well-publicized malpractice case can ruin the doctor's career and practice. The law, like medicine, is an inexact science. One cannot predict with certainty an outcome of cases many a time. It depends on the particular facts and circumstances of the case, and also the personal notions of the judge concerned who is hearing the case. The axiom “you learn from your mistakes” is too little honored in healthcare. The best way to handle medico-legal issues is by preventing them, and this article tries to enumerate the preventive measures in safeguarding the doctor against negligence suit.

    Although certain risk factors can identify individuals who are most likely to develop chronic pain, few interventions to prevent chronic pain have been identified. To facilitate the identification of preventive interventions, an IMMPACT meeting was convened to discuss research design considerations for clinical trials investigating the prevention of chronic pain. We present general design considerations for prevention trials in populations that are at relatively high risk for developing chronic pain. Specific design considerations included subject identification, timing and duration of treatment, outcomes, timing of assessment, and adjusting for risk factors in the analyses. We provide a detailed examination of 4 models of chronic pain prevention (i.e., chronic post-surgical pain, postherpetic neuralgia, chronic low back pain, and painful chemotherapy-induced peripheral neuropathy). The issues discussed can, in many instances, be extrapolated to other chronic pain conditions. These examples were selected because they are representative models of primary and secondary prevention, reflect persistent pain resulting from multiple insults (i.e., surgery, viral infection, injury, and toxic/noxious element exposure), and are chronically painful conditions that are treated with a range of interventions. Improvements in the design of chronic pain prevention trials could improve assay sensitivity and thus accelerate the identification of efficacious interventions. Such interventions would have the potential to reduce the prevalence of chronic pain in the population. Additionally, standardization of outcomes in prevention clinical trials will facilitate meta-analyses and systematic reviews and improve detection of preventive strategies emerging from clinical trials.

  4. Maintenance planning for a deteriorating production process

    Ahmadi, Reza; Fouladirad, Mitra

    2017-01-01

    We consider a system subject to degradation, more precisely a production process with three quality states evolving according to a homogeneous Markov process. The degradation decreases the income generated by the system. To maintain revenue stream and prevent the loss of revenue, the system is inspected according to a Markov-modulated Poisson process. It is assumed that each inspection at time t incurs a time dependent cost. Each inspection improves the system health and therefore the degradation level jumps to a less deteriorated state. In absence of inspections, the system state is prone to shift to a more deteriorated state with a constant rate. The problem is to determine an optimal operating (stopping) time which truly balances some flow of income and increasing costs due to inspections, and so maximizes the expected gain of the proposed policy. To demonstrate the applicability of the explored approach and its effectiveness, some numerical results are provided. - Highlights: • An integrated model based on a quality state-dependent reward structure is explored. • The model allows the revenue stream responds to variation in the quality state. • The production process is inspected according to a Markovmodulated Poisson process. • Assuming a Markovian structure, we predict the quality state behavior. • We determine an optimal production run length based on a stopping decision rule.

All RCTs reported statistically significant results favouring PSSE but none reported on clinical significance. The number needed to treat (NNT helps determine if RCT results are clinically meaningful. The NNT is the number of patients that need to be treated to prevent one bad outcome in a given period. A low NNT suggests that a therapy has positive outcomes in most patients offered the therapy. The objective was to determine how many patients require Schroth PSSE added to standard care (observation or brace treatment to prevent one progression (NNT of the Largest Curve (LC or Sum of Curves (SOC beyond 5° and 10°, respectively over a 6-month interval. Methods This was a secondary analysis of a RCT. Fifty consecutive participants from a scoliosis clinic were randomized to the Schroth PSSE + standard of care group (n = 25 or the standard of care group (n = 25. We included males and females with AIS, age 10–18 years, all curve types, with curves 10°- 45°, with or without brace, and all maturity levels. We excluded patients awaiting surgery, having had surgery, having completed brace treatment and with other scoliosis diagnoses. The local ethics review board approved the study (Pro00011552. The Schroth intervention consisted of weekly 1-h supervised Schroth PSSE sessions and a daily home program delivered over six months in addition to the standard of care. A prescription algorithm was used to determine which exercises patients were to perform. Controls received only standard of care. Cobb angles were measured using a semi-automatic system from posterior-anterior standing radiographs at baseline and 6 months. We calculated absolute risk reduction (ARR and relative risk reduction (RRR. The NTT was calculated as: NNT = 1/ARR. Patients with missing values (PSSE

    Low back pain (LBP) is a prevalent condition and a socioeconomic problem in many countries. Due to its recurrent nature, the prevention of further episodes (secondary prevention), seems logical. Furthermore, when the condition is persistent, the minimization of symptoms and prevention of deterioration (tertiary prevention), is equally important. Research has largely focused on treatment methods for symptomatic episodes, and little is known about preventive treatment strategies. This study protocol describes a randomized controlled clinical trial in a multicenter setting investigating the effect and cost-effectiveness of preventive manual care (chiropractic maintenance care) in a population of patients with recurrent or persistent LBP.Four hundred consecutive study subjects with recurrent or persistent LBP will be recruited from chiropractic clinics in Sweden. The primary outcome is the number of days with bothersome pain over 12 months. Secondary measures are self-rated health (EQ-5D), function (the Roland Morris Disability Questionnaire), psychological profile (the Multidimensional Pain Inventory), pain intensity (the Numeric Rating Scale), and work absence.The primary utility measure of the study is quality-adjusted life years and will be calculated using the EQ-5D questionnaire. Direct medical costs as well as indirect costs will be considered.Subjects are randomly allocated into two treatment arms: 1) Symptom-guided treatment (patient controlled), receiving care when patients feel a need. 2) Preventive treatment (clinician controlled), receiving care on a regular basis. Eligibility screening takes place in two phases: first, when assessing the primary inclusion/exclusion criteria, and then to only include fast responders, i.e., subjects who respond well to initial treatment. Data are collected at baseline and at follow-up as well as weekly, using SMS text messages. This study investigates a manual strategy (chiropractic maintenance care) for recurrent and

    Rural-urban disparities in provision of preventive services exist, but there is sparse research on how rural, suburban, or urban differences impact physician adherence to clinical preventive service guidelines. We aimed to identify factors that may cause differences in adherence to preventive service guidelines among rural, suburban, and urban primary care physicians. This qualitative study involved in-depth semistructured interviews with 29 purposively sampled primary care physicians (10 rural, 10 suburban, 9 urban) in Missouri. Physicians were asked to describe barriers and facilitators to clinical preventive service guideline adherence. Using techniques from grounded theory analysis, 2 coders first independently conducted content analysis then reconciled differences in coding to ensure agreement on intended meaning of transcripts. Patient epidemiologic differences, distance to health care services, and care coordination were reported as prominent factors that produced differences in preventive service guideline adherence among rural, suburban, and urban physicians. Epidemiologic differences impacted all physicians, but rural physicians highlighted the importance of occupational risk factors in their patients. Greater distance to health care services reduced visit frequency and was a prominent barrier for rural physicians. Care coordination among health care providers was problematic for suburban and urban physicians. Patient resistance to medical care and inadequate access to resources and specialists were identified as barriers by some rural physicians. The rural, suburban, or urban context impacts whether a physician will adhere to clinical preventive service guidelines. Efforts to increase guideline adherence should consider the barriers and facilitators unique to rural, suburban, or urban areas. © 2013 National Rural Health Association.

    The purpose of this study was to construct and test a structural equation model for pressure ulcer prevention action by clinical nurses. The Health Belief Model and the Theory of Planned Behavior were used as the basis for the study. A structured questionnaire was completed by 251 clinical nurses to analyze the relationships between concepts of perceived benefits, perceived barriers, attitude, subjective norm, perceived control, intention to perform action and behavior. SPSS 22.0 and AMOS 22.0 programs were used to analyze the efficiency of the hypothesized model and calculate the direct and indirect effects of factors affecting pressure ulcer prevention action among clinical nurses. The model fitness statistics of the hypothetical model fitted to the recommended levels. Attitude, subjective norm and perceived control on pressure ulcer prevention action explained 64.2% for intention to perform prevention action. The major findings of this study indicate that it is essential to recognize improvement in positive attitude for pressure ulcer prevention action and a need for systematic education programs to increase perceived control for prevention action.

    The promise of combination HIV prevention-the application of multiple HIV prevention interventions to maximise population-level effects-has never been greater. However, to succeed in achieving significant reductions in HIV incidence, an additional concept needs to be considered: combination implementation. Combination implementation for HIV prevention is the pragmatic, localised application of evidence-based strategies to enable high sustained uptake and quality of interventions for prevention of HIV. In this Review, we explore diverse implementation strategies including HIV testing and counselling models, task shifting, linkage to and retention in care, antiretroviral therapy support, behaviour change, demand creation, and structural interventions, and discusses how they could be used to complement HIV prevention efforts such as medical male circumcision and treatment as prevention. HIV prevention and treatment have arrived at a pivotal moment when combination efforts might result in substantial enough population-level effects to reverse the epidemic and drive towards elimination of HIV. Only through careful consideration of how to implement and operationalise HIV prevention interventions will the HIV community be able to move from clinical trial evidence to population-level effects.

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

    The paper deals with the justification and description of clinical and organizational approaches to preventing cardiovascular diseases (CVD) in the primary health care system (PHCS) under the present conditions of health care modernization in Russia. It formulates the basic directions of systematic measures in integration strategies for the prevention of noncommunicable diseases (mainly CVD) at a federal level, in which practical measures are presented to improve a system for the early detection of high-risk individuals and to carry out measures for risk factor correction in PHCS, i.e. to implement high-risk strategies, including clinical and organizational approaches to reconstituting the medical prevention infrastructure in PHCS. This is favored by the new normative documents adopted by the Ministry of Health of Russia on the follow-up and prophylactic medical examinations of the adult population. The paper substantiates the objective need for such examinations and characterizes the main clinical and organizational approaches promoted in medical examinations, which is aimed at introducing the current science-based and economically expedient methods in the real practice of PHCS for the early identifications of atherosclerosis-induced major CVDs and, what is particularly important, a risk for their development. Prophylactic counseling as a compulsory component is first being introduced in medical examination procedures. The key clinical and organizational principle of effective CVD prevention in public health is the implementation of the relationship and continuity of preventive measures, which becomes realistic with the adoption of new regulations of clinical examinations, prophylactic medical examinations, and follow-ups. The improvement of CVD prevention is associated not only with the introduction of organizational innovation changes, but also with the need to create a prevention ideology in physicians at all levels. It is emphasized that a comprehensive

    To present clinical information relevant to acute respiratory distress syndrome (ARDS) and its appearance in chiropractic acute care practice. The National Library of Medicine MEDLINE database was used, along with the bibliographies of selected articles and textbooks commonly found in chiropractic college libraries and bookstores. Clinical studies from the English literature were selected if they pertained to incidence, clinical relevancy, or the association of ARDS with commonly-seen diagnoses in chiropractic neuromusculoskeletal or orthopedic practice. All relevant studies identified by the search were evaluated based on information pertinent to chiropractic management of acute care patients. ARDS is a pulmonary distress syndrome with a high mortality rate. Recognizable indications for the possible development of ARDS include chest pain, head injury, and thoracic spine pain with or without trauma. Clinical evaluation, radiographic findings, and laboratory findings are presented to assist practitioners in identifying this disease process of multiple etiology. A study of the basic pathophysiologic processes that occur in the formation of ARDS is presented to help practitioners gain clinical appreciation. Strategies for preventing respiratory distress in chiropractic patients are also presented and include use of the postural position and the clinical maxim of "slow, deep breathing despite pain" to lessen incident rates of subjects at risk. Although ARDS may not be prevalent in chiropractic practice, it is important for physicians to be aware of the clinical basics (including its pathophysiology), its medical significance, and the preventive strategies that may be used to minimize its occurrence. This basic understanding will further advance knowledge of this disease complex.

    Cardiovascular disease (CVD) in the ageing is a major public health problem worldwide. The nature of most CVD is subclinical with pathological processes that can span over years. Use of preventive measures could be an appropriate approach to prevailing over CVD in the ageing, and herbal medicine is one of the promising preventive approaches and is currently of interest among medical societies. In the evidence-based era, herbal medicine is, however, often underestimated and approached with skepticism, mainly due to the paucity of scientific evidence. Properly designed clinical trials on herbal medicine for prevention of CVD in a geriatric population are thus of importance and of clinical value. To review ethical issues and discuss considerations when such research is proposed. Four ethical issues, including the scientific validity of research, risk-benefit assessments, subject selection and vulnerability, and informed consent, are structured and extensively discussed in this article. Ethical core considerations of prevention research of CVD on herbal medicine involve particular attention on the scientific validity of research, risk-benefit assessments, subject selection and vulnerability, and informed consent. These issues and considerations are keys, although they must be adapted to an individual research setting in which a clinical study is proposed. Copyright © 2015 Elsevier GmbH. All rights reserved.

    To explore youth clinic midwives role in cervical cancer prevention and their attitude to HPV vaccination. Individual interviews with 13 midwives working at youth clinics in Sweden. The interviews were recorded, transcribed, and analysed by qualitative content analysis. Three themes were identified in the qualitative content analysis: "Cervical cancer prevention not a prioritised area", "Ambivalence to the HPV vaccine", and "Gender and socioeconomic controversies". Few midwives talked spontaneously about cervical cancer prevention. The responsibility for providing information about HPV vaccination was considered as primarily that of school health nurses and parents. Midwives were positive about the HPV vaccination, but recognised certain risks, such as its potential negative impact on cervical cancer screening and increased sexual risk taking. The midwives expressed concerns with medical risks, such as side effects and unknown long-term effects of the HPV vaccine. The midwives in the study had ethical concerns that boys were not included in the program and not all families had the financial resources to vaccinate their children. Thus, weak socioeconomic groups might be excluded. The midwives considered cervical cancer prevention as important, but did not integrate information on the HPV vaccine into their routine work, mainly because young people visiting youth clinics had had their sexual debut and they were concerned about the medical risks and that the vaccine was too expensive.

    Full Text Available Suicide is reaching epidemic proportions, with over 44,000 deaths by suicide in the US, and 800,000 worldwide in 2015. This, despite research and development of evidence-based interventions that target suicidal behavior directly. Suicide prevention efforts need a comprehensive approach, and research must lead to effective implementation across public and mental health systems. A 10-year systematic review of evidence-based findings in suicide prevention summarized the areas necessary for translating research into practice. These include risk assessment, means restriction, evidence-based treatments, population screening combined with chain of care, monitoring, and follow-up. In this article, we review how suicide prevention research informs implementation in clinical settings where those most at risk present for care. Evidence-based and best practices address the fluctuating nature of suicide risk, which requires ongoing risk assessment, direct intervention and monitoring. In the US, the National Action Alliance for Suicide Prevention has put forth the Zero Suicide (ZS Model, a framework to coordinate a multilevel approach to implementing evidence-based practices. We present the Assess, Intervene and Monitor for Suicide Prevention model (AIM-SP as a guide for implementation of ZS evidence-based and best practices in clinical settings. Ten basic steps for clinical management model will be described and illustrated through case vignette. These steps are designed to be easily incorporated into standard clinical practice to enhance suicide risk assessment, brief interventions to increase safety and teach coping strategies and to improve ongoing contact and monitoring of high-risk individuals during transitions in care and high risk periods.

  7. Evaluation of the olivocochlear efferent reflex strength in the susceptibility to temporary hearing deterioration after music exposure in young adults

    2014-01-01

    Full Text Available The objective of the current study was to evaluate the predictive role of the olivocochlear efferent reflex strength in temporary hearing deterioration in young adults exposed to music. This was based on the fact that a noise-protective role of the medial olivocochlear (MOC system was observed in animals and that efferent suppression (ES measured using contralateral acoustic stimulation (CAS of otoacoustic emissions (OAEs is capable of exploring the MOC system. Knowing an individual′s susceptibility to cochlear damage after noise exposure would enhance preventive strategies for noise-induced hearing loss. The hearing status of 28 young adults was evaluated using pure-tone audiometry, transient evoked OAEs (TEOAEs and distortion product OAEs (DPOAEs before and after listening to music using an MP3 player during 1 h at an individually determined loud listening level. CAS of TEOAEs was measured before music exposure to determine the amount of ES. Regression analysis showed a distinctive positive correlation between temporary hearing deterioration and the preferred gain setting of the MP3 player. However, no clear relationship between temporary hearing deterioration and the amount of ES was found. In conclusion, clinical measurement of ES, using CAS of TEOAEs, is not correlated with the amount of temporary hearing deterioration after 1 h music exposure in young adults. However, it is possible that the temporary hearing deterioration in the current study was insufficient to activate the MOC system. More research regarding ES might provide more insight in the olivocochlear efferent pathways and their role in auditory functioning.

    The aim of this study was to determine the ability of undenatured native chicken type II collagen (UC-II) to prevent excessive articular cartilage deterioration in a rat model of osteoarthritis (OA). Twenty male rats were subjected to partial medial meniscectomy tear (PMMT) surgery to induce OA. Immediately after the surgery 10 rats received vehicle and another 10 rats oral daily dose of UC-II at 0.66 mg/kg for a period of 8 weeks. In addition 10 naïve rats were used as an intact control and another 10 rats received sham surgery. Study endpoints included a weight-bearing capacity of front and hind legs, serum biomarkers of bone and cartilage metabolism, analyses of subchondral and cancellous bone at the tibial epiphysis and metaphysis, and cartilage pathology at the medial tibial plateau using histological methods. PMMT surgery produced moderate OA at the medial tibial plateau. Specifically, the deterioration of articular cartilage negatively impacted the weight bearing capacity of the operated limb. Immediate treatment with the UC-II preserved the weight-bearing capacity of the injured leg, preserved integrity of the cancellous bone at tibial metaphysis and limited the excessive osteophyte formation and deterioration of articular cartilage. Study results demonstrate that a clinically relevant daily dose of UC-II when applied immediately after injury can improve the mechanical function of the injured knee and prevent excessive deterioration of articular cartilage.

    Noise induced hearing loss is a slowly developing hearing impairment, caused by occupational exposure to excessive noise levels, constitutes a lesion of the auditory analyzer and clinically manifested as chronic bilateral sensorineural hearing loss. Currently, there is not a treatment that provide a cure of sensorineural hearing loss. Regular, individually tailored treatment should be directed to the pathogenic mechanisms and specific clinical symptoms of hearing loss, as well as the prevention of complications. We recommend using non-drug therapies that can improve blood flow in labyrinth, tissue and cellular metabolism.

The aim of this study was to assess the perceived barriers to practice change by eliciting nurses' opinions with regard to barriers to, and facilitators of, implementation of a Fall Prevention clinical practice guideline in five acute care hospitals in Singapore. Methods Nurses were surveyed to identify their perceptions regarding barriers to implementation of clinical practice guidelines in their practice setting. The validated questionnaire, 'Barriers and facilitators assessment instrument', was administered to nurses (n = 1830 working in the medical, surgical, geriatric units, at five acute care hospitals in Singapore. Results An 80.2% response rate was achieved. The greatest barriers to implementation of clinical practice guidelines reported included: knowledge and motivation, availability of support staff, access to facilities, health status of patients, and, education of staff and patients. Conclusion Numerous barriers to the use of the Fall Prevention Clinical Practice Guideline have been identified. This study has laid the foundation for further research into implementation of clinical practice guidelines in Singapore by identifying barriers to change in acute care settings.

    A randomized clinical trial compared two materials used to prevent epidural scarring after microdiscectomy. To determine whether ADCON-L Gel (ALG) or Preclude Spinal Membrane (PSM) was more effective in preventing scarring, reducing pain, and improving quality of life postoperatively. Postdiscectomy syndrome may result from epidural scarring. Various materials have been used in attempts to prevent this problem, but none have provided optimal results. Previous laboratory and clinical studies have found ALG and PSM to be effective, but none compared the two materials. Thirty-one patients undergoing primary microdiscectomy were randomly assigned to receive either ALG or PSM. Postoperatively, patients were evaluated by magnetic resonance imaging (MRI), with contrast, for volume and rostral-caudal extent of scar tissue and nerve root involvement. Back and leg pain and quality of life were assessed by neurologic examinations and standardized patient surveys. Findings at any reoperations were recorded. Results in the PSM (n = 18) and ALG (n = 13) groups were compared statistically. No operative or postoperative complications occurred. Two patients in each group required reoperation. MRI at 6 months showed no, mild or mild-moderate scarring in most patients, with no significant differences between the ALG and PSM groups in scar volume and extent or nerve root involvement. Neurologic examinations and patient surveys showed substantial reductions in pain over time in both groups but no significant differences between groups. PSM was easy to see and remove at reoperation. PSM and ALG are equally effective in preventing epidural scarring associated with postdiscectomy syndrome.

    Obesity impacts the U.S. military by affecting the health and readiness of active duty service members and their families. Preventing Obesity in Military Communities (POMC) is a comprehensive research program within Patient Centered Medical Homes (PCMHs) in three Military Training Facilities. This paper describes three pilot randomized controlled trials that target critical high risk periods for unhealthy weight gain from birth to young adulthood: (1) pregnancy and early infancy (POMC-Mother-Baby), (2) adolescence (POMC-Adolescent), and (3) the first tour of duty after boot camp (POMC-Early Career). Each study employs a two-group randomized treatment or prevention program with follow up. POMC offers a unique opportunity to bring together research and clinical expertise in obesity prevention to develop state-of-the-art programs within PCMHs in Military Training Facilities. This research builds on existing infrastructure that is expected to have immediate clinical benefits to DoD and far-reaching potential for ongoing collaborative work. POMC may offer an economical approach for widespread obesity prevention, from conception to young adulthood, in the U.S. military as well as in civilian communities. PMID:25648176

    Leading scientific and organizational prerequisites for the feasibility of clinical examination of the entire child population of the Russian Federation to the dentist is, above all, the high prevalence and intensity of dental diseases in children of all ages. As a result of many years of research and follow-up of children of preschool and school age we have proved the need to distinguish a group of children with zero activity of dental caries. The referring criteria are determined according to the results of comprehensive clinical and laboratory examination in order to determine the degree of risk of dental caries and individual caries resistance. The age-specific risk group is settled by "Stop caries" software. In order to optimize the preventive activities children are divided in 5 groups for routine preventive dental care. Unfortunately the efforts of modern dental services aimed at eliminating the consequences of caries process by filling cavities. Individualized preventive approach will increase the effectiveness of preventive measures and save public funds allocated in the amount of compulsory health insurance for pediatric dentistry.

  15. Public Health Investment in Team Care: Increasing Access to Clinical Preventive Services in Los Angeles County

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available As part of federal and local efforts to increase access to high quality, clinical preventive services (CPS in underserved populations, the Los Angeles County Department of Public Health (DPH partnered with six local health system and community organization partners to promote the use of team care for CPS delivery. Although these partners were at different stages of organizational capacity, post-program review suggests that each organization advanced team care in their clinical or community environments, potentially affecting >250,000 client visits per year. Despite existing infrastructure and DPH’s funding support of CPS integration, partner efforts faced several challenges. They included lack of sustainable funding for prevention services; limited access to community resources that support disease prevention; and difficulties in changing health-care provider behavior. Although team care can serve as a catalyst or vehicle for delivering CPS, downstream sustainability of this model of practice requires further state and national policy changes that prioritize prevention. Public health is well positioned to facilitate these policy discussions and to assist health system and community organizations in strengthening CPS integration.

  20. Offering pre-exposure prophylaxis for HIV prevention to pregnant and postpartum women: a clinical approach.

    2017-03-08

    HIV prevention during pregnancy and lactation is critical for both maternal and child health. Pregnancy provides a critical opportunity for clinicians to elicit women's vulnerabilities to HIV and offer HIV testing, treatment and referral and/or comprehensive HIV prevention options for the current pregnancy, the postpartum period and safer conception options for future pregnancies. In this commentary, we review the safety of oral pre-exposure prophylaxis with tenofovir/emtricitabine in pregnant and lactating women and suggest opportunities to identify pregnant and postpartum women at substantial risk of HIV. We then describe a clinical approach to caring for women who both choose and decline pre-exposure prophylaxis during pregnancy and postpartum, highlighting areas for future research. Evidence suggests that pre-exposure prophylaxis with tenofovir/emtricitabine is safe in pregnancy and lactation. Identifying women vulnerable to HIV and eligible for pre-exposure prophylaxis is challenging in light of the myriad of individual, community, and structural forces impacting HIV acquisition. Validated risk calculators exist for specific populations but have not been used to screen and offer HIV prevention methods. Partner testing and engagement of men living with HIV are additional means of reaching at-risk women. However, women's vulnerabilities to HIV change over time. Combining screening for HIV vulnerability with HIV and/or STI testing at standard intervals during pregnancy is a practical way to prompt providers to incorporate HIV screening and prevention counselling. We suggest using shared decision-making to offer women pre-exposure prophylaxis as one of multiple HIV prevention strategies during pregnancy and postpartum, facilitating open conversations about HIV vulnerabilities, preferences about HIV prevention strategies, and choosing a method that best meets the needs of each woman. Growing evidence suggests that pre-exposure prophylaxis with tenofovir

    The doctoral thesis is based on eight papers published in peer-reviewed journals and a review of the literature. The papers are published between 1997 and 2013 in cooperation with Sankt Elisabeth Hospital, Herlev Hospital, Glostrup Hospital, Rigshospitalet, Hvidovre Hospital, Amager Hospital, Copenhagen Trial Unit, and Institute of Preventive Medicine, Copenhagen. Groin injuries in sport are very common and in football they are among the most common and most time-consuming injuries. These injuries are treated very differently around the world. There is no consensus in the literature regarding definitions, examination methods, diagnosis or treatment and in general the level of evidence is very low. There is a need for identification of the painful anatomical structures, how to examine them and how to define clinical entities to develop effective treatment and prevention. The aim of these studies were: - To review the literature to create an overview of the ideas and the knowledge in order to plan future studies in this field. - Develop and test clinical examination techniques of the relevant tendons and muscles in the region. - Since no evidence-based diagnosis exist; to develop a set of clinical entities to identify the different groups of patients. - To test the effect of a dedicated exercise program developed for treatment of long-standing adductor-related groin pain in athletes in a randomised clinical trial comparing it to the treatment modalities used at that time. - To examine the long-term effect of the above mentioned training program for treatment of long-standing adductor-related groin pain. - To develop a training program for prevention of groin injuries in soccer and test it in a randomised clinical trial. - To describe the occurrence and presentation in clinical entities of groin injuries in male football and to examine the characteristics of these injuries. - Evaluate if radiological signs of femuro-acetabular impingement (FAI) or dysplasia affect the

    Full Text Available We report a case of paradoxical deterioration. A male patient diagnosed with pleural tuberculosis, but who was not infected with human immunodeficiency virus (HIV, experienced clinical deterioration 3 weeks after the initiation of anti-tuberculous treatment. After other diagnoses were ruled out, a paradoxical response to treatment was established and the patient was started on systemic corticosteroids. Paradoxical response to treatment should be considered in patients with clinical deterioration after they start on anti-tuberculous treatment.

  3. Evaluating the combined efficacy of polymers with fungicides for protection of museum textiles against fungal deterioration in Egypt.

    Fungal deterioration is one of the highest risk factors for damage of historical textile objects in Egypt. This paper represents both a study case about the fungal microflora deteriorating historical textiles in the Egyptian Museum and the Coptic museum in Cairo, and evaluation of the efficacy of several combinations of polymers with fungicides for the reinforcement of textiles and their prevention against fungal deterioration. Both cotton swab technique and biodeteriorated textile part technique were used for isolation of fungi from historical textile objects. The plate method with the manual key was used for identification of fungi. The results show that the most dominant fungi isolated from the tested textile samples belong to Alternaria, Aspergillus, Chaetomium, Penicillium and Trichoderma species. Microbiological testing was used for evaluating the usefulness of the suggested conservation materials (polymers combined with fungicides) in prevention of the fungal deterioration of ancient Egyptian textiles. Textile samples were treated with 4 selected polymers combined with two selected fungicides. Untreated and treated textile samples were deteriorated by 3 selected active fungal strains isolated from ancient Egyptian textiles. This study reports that most of the tested polymers combined with the tested fungicides prevented the fungal deterioration of textiles. Treatment of ancient textiles by suggested polymers combined with the suggested fungicides not only reinforces these textiles, but also prevents fungal deterioration and increases the durability of these textiles. The tested polymers without fungicides reduce the fungal deterioration of textiles but do not prevent it completely.

  4. The prevention of diabetic foot ulceration: how biomechanical research informs clinical practice

    Directory of Open Access Journals (Sweden)

    Frank E. DiLiberto

    Full Text Available ABSTRACT Background Implementation of interprofessional clinical guidelines for the prevention of neuropathic diabetic foot ulceration has demonstrated positive effects regarding ulceration and amputation rates. Current foot care recommendations are primarily based on research regarding the prevention of ulcer recurrence and focused on reducing the magnitude of plantar stress (pressure overload. Yet, foot ulceration remains to be a prevalent and debilitating consequence of Diabetes Mellitus. There is limited evidence targeting the prevention of first-time ulceration, and there is a need to consider additional factors of plantar stress to supplement current guidelines. Objectives The first purpose of this article is to discuss the biomechanical theory underpinning diabetic foot ulcerations and illustrate how plantar tissue underloading may precede overloading and breakdown. The second purpose of this commentary is to discuss how advances in biomechanical foot modeling can inform clinical practice in the prevention of first-time ulceration. Discussion Research demonstrates that progressive weight-bearing activity programs to address the frequency of plantar stress and avoid underloading do not increase ulceration risk. Multi-segment foot modeling studies indicate that dynamic foot function of the midfoot and forefoot is compromised in people with diabetes. Emerging research demonstrates that implementation of foot-specific exercises may positively influence dynamic foot function and improve plantar stress in people with diabetes. Conclusion Continued work is needed to determine how to best design and integrate activity recommendations and foot-specific exercise programs into the current interprofessional paradigm for the prevention of first-time ulceration in people with Diabetes Mellitus.

    Full Text Available Multitasking scheduling problems with a deterioration effect incurred by coexisting behavioral phenomena in human-related scheduling systems including deteriorating task processing times and deteriorating rate-modifying activity (DRMA of human operators are addressed. Under the assumption of this problem, the processing of a selected task suffers from the joint effect of available but unfinished waiting tasks, the position-dependent deterioration of task processing time, and the DRMA of human operators. Traditionally, these issues have been considered separately; herein, we address their integration. We propose optimal algorithms to solve the problems to minimize makespan and the total absolute differences in completion time, respectively. Based on the analysis, some special cases and extensions are also discussed.

    2006-09-01

    Full Text Available HMGCoA-inhibitors (statins lower plasma cholesterol through interference with the rate-limiting enzyme in the endogenous synthesis process. Since their introduction in the early 90’s, the clinical attitude towards cardiovascular (cv risk reduction has evolved from the attention to single risk factors to a more comprehensive global risk evaluation, and thus the indications of statins have broadened from the secondary prevention in hypercholesterolemic patients to include primary prevention in mildly and moderately hypercholesterolemic, or even normocholesterolemic patients, provided their global cv risk is considered high (typically, an estimated major cv event probability greater than 20%. Italian drug utilization data show that a small proportion of patients who could benefit from statins do actually receive them, contributing to the persistence of the clinical and economical burden of cv disease, the leading cause of mortality; since statins have proved effective, and cost-effective, in cv prevention, a more widespread use appears desirable, but requires high investments in pharmaceutical costs. This article defines a clinical profile of lovastatin, a statin with a solid efficacy and safety record only recently introduced into the Italian market despite it has been the first to become clinically available abroad. Among available statin formulations appropriate for target cholesterol reductions up to 30%, which apply to a significant proportion of statin therapy candidates, lovastatin 20 mg is marketed at the lowest price. Although the individual response to the different statins is highly unpredictable, determining a mandatory empirical molecule- and dose-finding strategy on the single patient, from the societal point of view the choice to start with lower cost molecules, among options that on average are equally-effective, may limit initial drug investment and dampen the impact of resource waste secondary to treatment interruptions and

    1993-01-01

    Under the sponsorship of IHI and EPRI, a rule-based screening system has been developed that can be used by utility engineers to determine which deterioration mechanisms are acting on specific LWR components, and to evaluate the efficacy of an age-related deterioration management program. The screening system was developed using the rule-based shell, NEXPERT, which provides traceability to the data sources used in the logic development. The system addresses all the deterioration mechanisms of specific metals encountered in either BWRs or PWRs. Deterioration mechanisms are listed with reasons why they may occur during the design life of LWRs, considering the plant environment, manufacturing process, service history, material chemical composition, etc. of components in a specific location of a LWR. To eliminate the evaluation of inactive deterioration quickly, a tier structure is applied to the rules. The reasons why deterioration will occur are extracted automatically by backward chaining. To reduce the amount of user input, plant environmental data are stored in files as default environmental data. (author)

  13. Clinical preventive services in Guatemala: a cross-sectional survey of internal medicine physicians.

    Directory of Open Access Journals (Sweden)

    Juan E Corral

    Full Text Available Guatemala is currently undergoing an epidemiologic transition. Preventive services are key to reducing the burden of non-communicable diseases, and smoking counseling and cessation are among the most cost-effective and wide-reaching strategies. Internal medicine physicians are fundamental to providing such services, and their knowledge is a cornerstone of non-communicable disease control.A national cross-sectional survey was conducted in 2011 to evaluate knowledge of clinical preventive services for non-communicable diseases. Interns, residents, and attending physicians of the internal medicine departments of all teaching hospitals in Guatemala completed a self-administered questionnaire. Participants' responses were contrasted with the Guatemalan Ministry of Health (MoH prevention guidelines and the US Preventive Services Task Force (USPSTF recommendations. Analysis compared knowledge of recommendations within and between hospitals.In response to simulated patient scenarios, all services were recommended by more than half of physicians regardless of MoH or USPSTF recommendations. Prioritization was adequate according to the MoH guidelines but not including other potentially effective services (e.g. colorectal cancer and lipid disorder screenings. With the exception of colorectal and prostate cancer screening, less frequently recommended by interns, there was no difference in recommendation rates by level.Guatemalan internal medicine physicians' knowledge on preventive services recommendations for non-communicable diseases is limited, and prioritization did not reflect cost-effectiveness. Based on these data we recommend that preventive medicine training be strengthened and development of evidence-based guidelines for low-middle income countries be a priority.

    The Mahalapye district health management team (DHMT) conducts regular audits to evaluate the standard of services delivered to patients, one of which is the prevention of mother-to-child-transmission (PMTCT) programme. Xhosa clinic is one of the facilities in Mahalapye which provides a PMTCT programme. This audit aimed to identify gaps between the current PMTCT clinical practice in Xhosa clinic and the Botswana PMTCT national guidelines. This audit took place in Xhosa clinic in the urban village of Mahalapye, in the Central District of Botswana. This was a retrospective audit using PMTCT Xhosa clinic records of pregnant mothers and HIV-exposed babies seen from January 2013 to June 2013. One hundred and thirty-three pregnant women registered for antenatal care. Twenty-five (19%) knew their HIV-positive status as they had been tested before their pregnancy or had tested HIV positive at their first antenatal clinic visit. More than two-thirds of the 115 pregnant women (69%) were seen at a gestational age of between 14 and 28 weeks. About two-thirds of the pregnant women (67%) took antiretroviral drugs. Of the 44 HIV-exposed infants, 39 (89%) were HIV DNA PCR negative at 6 weeks. Thirty-two (73%) children were given cotrimoxazole prophylaxis between 6 and 8 weeks. The PMTCT programme service delivery was still suboptimal and could potentially increase the mother-to-child transmission of HIV. Daily monitoring mechanism to track those eligible could help to close the gap.

    Salivary dysfunction in Sjögren disease can lead to serious and costly oral health complications. Clinical practice guidelines for caries prevention in Sjögren disease were developed to improve quality and consistency of care. A national panel of experts devised clinical questions in a Population, Intervention, Comparison, Outcomes format and included use of fluoride, salivary stimulants, antimicrobial agents, and nonfluoride remineralizing agents. The panel conducted a systematic search of the literature according to pre-established parameters. At least 2 members extracted the data, and the panel rated the strength of the recommendations by using a variation of grading of recommendations, assessment, development, and evaluation. After a Delphi consensus panel was conducted, the experts finalized the recommendations, with a minimum of 75% agreement required. Final recommendations for patients with Sjögren disease with dry mouth were as follows: topical fluoride should be used in all patients (strong); although no study results link improved salivary flow to caries prevention, the oral health community generally accepts that increasing saliva may contribute to decreased caries incidence, so increasing saliva through gustatory, masticatory, or pharmaceutical stimulation may be considered (weak); chlorhexidine administered as varnish, gel, or rinse may be considered (weak); and nonfluoride remineralizing agents may be considered as an adjunct therapy (moderate). The incidence of caries in patients with Sjögren disease can be reduced with the use of topical fluoride and other preventive strategies. Copyright © 2016 American Dental Association.

    The design and execution of prevention trials for OA have methodological issues that are distinct from trials designed to impact prevalent disease. Disease definitions and their precise and sensitive measurement, identification of high-risk populations, the nature of the intervention (pharmaceutical, nutraceutical, behavioral) and its potential pleiotropic impacts on other organ systems are critical to consider. Because prevention trials may be prolonged, close attention to concomitant life changes and co-morbidities, adherence and participant retention in the trial is of primary importance, as is recognition of the potential for "preventive misconception" and "behavioral disinhibition" to affect the ability of the trial to show an effect of the intervention under study. None of these potential pitfalls precludes a successful and scientifically rigorous process and outcome. As technology improves the means to measure and predict the OA process and its clinical consequences, it will be increasingly possible to screen individuals for high-risk phenotypes, combining clinical factors with information from imaging, genetic, metabolic and other biomarkers and to impact this high-risk condition to avoid or delay OA both structurally and symptomatically.

    2016-02-01

    Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system. Neurological impairments are caused by axonal damage due to demyelination and neuroinflammation within the central nervous system. T cells mediate the neuroinflammation. The activation of T cells is induced by the release of adenosine triphosphate and involves purinergic receptors as well as pannexin (Panx) proteins. As Panx1 is expressed on T cells, we here propose that application of probenecid, a known Panx inhibitor, will prevent the onset of clinical symptoms in a mouse model of MS, the experimental autoimmune encephalomyelitis (EAE) model. EAE-induced mice received daily injections of probenecid. Disease scores, T cell numbers, and microglia activation were compared between experimental groups. Probenecid treatment resulted in lower disease scores as compared to EAE animals. Probenecid-treated animals also displayed fewer inflammatory lesions. Microglia activation was not altered by treatment. In conclusion, probenecid prevented the onset of EAE.

    Excess weight and menopause are two major factors increasing aging women's vulnerability to chronic diseases. However, social position and socioeconomic status have also been identified as major determinants influencing both health behaviors and the development of such diseases. This study focuses on the socioeconomic variations of behavioral risk factors of chronic diseases in aging women. By drawing on Bourdieu's sociocultural theory of practice, 40 semistructured interviews were conducted to investigate preventive health practices of clinically overweight, postmenopausal women from contrasting socioeconomic classes living in Canada. Findings emphasize class-based differences with respect to long-term health and preventive practices according to three major themes: priority to long-term time horizons, attention given to risk factors of diseases, and control over future health. Health care providers should strive to work in concert with all subgroups of women to better understand their values, worldviews, and needs to decrease health inequalities after menopause.

    The cancer stem cell model introduces new strategies for the prevention and treatment of cancers. In cancers that appear to follow the stem cell model, pathways such as Wnt, Notch and Hedgehog may be targeted with natural compounds such as curcumin or drugs to reduce the risk of initiation of new tumors. Disease progression of established tumors could also potentially be inhibited by targeting the tumorigenic stem cells alone, rather than aiming to reduce overall tumor size. These new approaches mandate a change in the design of clinical trials and biomarkers chosen for efficacy assessment for preventative, neoadjuvant, adjuvant, and palliative treatments. Cancer treatments could be evaluated by assessing stem cell markers before and after treatment. Targeted stem cell specific treatment of cancers may not result in “complete” or “partial” responses radiologically, as stem cell targeting may not reduce the tumor bulk, but eliminate further tumorigenic potential. These changes are discussed using breast, pancreatic, and lung cancer as examples.

    More than three decades since its discovery, HIV infection remains one of the most aggressive epidemics worldwide, with more than 35 million people infected. In sub-Saharan Africa, heterosexual transmissions represent nearly 80% of new infections, with 50% of these occurring in women. In an effort to stop the dramatic spread of the HIV epidemic, new preventive treatments, such as microbicides, have been developed. Nanotechnology has revolutionized this field by designing and engineering novel highly effective nano-sized materials as microbicide candidates. This review illustrates the most recent advances in nanotech-derived HIV prevention strategies, as well as the main steps required to translate promising in vitro results into clinical trials.

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

    The eating habits modification is a clinical challenge, both on therapeutic and preventive levels, which requires tools from various areas of health, such as psychology and nutrition. In the structured work in these areas, that includes the referral to specialist consultants, there is a need of a first intervention in Primary Health Care, in clinical and community levels. In this paper, we attempt to systematize useful information for intervention. We will start by reviewing some important interviewing skills, some models of motivational interviewing, and we will make a brief reflection about the client. Then we will analyse an individual case structured in two complementary levels of interpretation: a closer look in general factors and another that reflect the antecedents, consequences and the description of the behaviour problem. We will also tackle issues related to the context in which the individual moves. We will analyse some group intervention programs within a clinical and preventive perspectives. Finally, we will discuss some concepts related to therapeutic adherence.

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

    Full Text Available Objective: BIONs™ (BIOnic Neurons are injectable, wireless microstimulators that make chronic BION Active Seating (BAS possible for pressure ulcer prevention (PUP. Neuromuscular electrical stimulation (NMES produces skeletal motion and activates trophic factors, counteracting three major etiological mechanisms leading to pressure ulcers (PUs: immobility, soft-tissue atrophy, and ischemia. Companion papers I and II reviewed prior experience with NMES for PUP, and analyzed the biomechanical considerations, respectively. This paper presents a treatment strategy derived from this analysis, and the clinical results of the first three cases.

    The nature of acute clinical deterioration has changed over the last three decades with a decrease in in-hospital cardiac arrests and an increase in acute clinical deterioration. Despite this change, research related to family presence continues to focus on care during resuscitation rather than during acute deterioration. To explore healthcare clinician attitudes, beliefs and perceptions of current practices surrounding family presence during episodes of acute deterioration in adult Emergency Department patients. Clinicians (n=156) from a single study site in Melbourne, Australia completed a 17-item survey. Participants disagreed that family members would interrupt (59.0%) or interfere (61.5%) with patient care if present during episodes of patient deterioration. Most (77.6%) participants stated that they included family during episodes of patient deterioration. Females, nurses and Australians/New Zealanders had a more positive attitude towards including family during episodes of patient deterioration when compared to males, doctors and clinicians of other ethnicities. Nurses with post-graduate qualifications and those with more years of experience had a more positive attitude towards including family during episodes of patient deterioration than nurses without post-graduation qualification and with less years of experience. Clinicians had predominantly positive attitudes towards including family during episodes of patient deterioration and perceived it to be a common day-to-day practice. Gender, profession, country of birth, education level and years of experience all impacted on clinician attitudes, beliefs and perceptions of family presence during acute deterioration.

    even when the temperature decreases to -20 ºC, and the second group F in which the pore water freezes. It has been found that the rocks from group N contain critical portion of adsorbed water in pores which prevents freezing of the pore water. The presence of adsorbed water enables thermodynamic processes related to osmosis which are dominantly responsible for deterioration of rocks from group N. A high correlation (R = 0.81) between content of adsorbed water and freeze-thaw loss was proved and can be used as durability estimator of rocks from group N. The rock deterioration of group F is caused not only by osmosis, but also by some other processes and influences, such as hydraulic pressure, permeability, grain size, rock and mineral tensile strength, degree of saturation, etc., and the deterioration cannot be predicted yet without the freeze-thaw test. Since the contents of absorbed water and ratio between adsorbed and bulk water (of which the absorbed water consists) is controlled by the porosity and pore structure, it can be concluded that the deterioration of some rocks is strongly related to rock pore structure.

    The aims of this study were to explore pressure ulcer incidences and practice variations in the nursing intervention provided for preventive pressure-ulcer care to patients either with pressure ulcers or at risk of pressure ulcers, and to examine them in relation to the patients' medical problems and the characteristics of the nurses who cared for them. The narrative nursing notes of 427 intensive-care patients who were discharged in 2007 that were documented at the point-of-care using standardized nursing statements were extracted from a clinical data repository at a teaching hospital in Korea and analyzed. The frequencies of five nursing interventions for pressure-ulcer prevention were compared between pressure-ulcer and pressure-ulcer risk groups, as were the characteristics of the nurses who were treating the patients in these two groups. Nursing interventions for pressure-ulcer prevention were also assessed relative to the patients' medical problems. The overall incidence of pressure ulcers was 15.0%. Position change was the most popular nursing intervention provided for pressure-ulcer prevention in both the pressure-ulcer and at-risk groups, followed by skin care. There was a statistically significant tendency toward a greater frequency of providing skin care and nutritional care in the at-risk group than in the pressure-ulcer group. There was no statistically significant difference in the mean frequencies of nursing interventions relative to the patients' medical problems in the pressure-ulcer group. However, frequencies of nursing interventions did differ significantly between patients with neurological problems and those with other medical problems in the at-risk group. Analysis of the nurses' characteristics revealed that more nursing interventions were documented by those who were younger, less experienced, and more educated. A standardized nursing-terminology-based electronic nursing record system allowed us to monitor the variations in nursing practice

    Our team is designing and fully characterizing black raspberry (BRB) food products suitable for long-term cancer prevention studies. The processing, scale-up, and storage effects on the consistency, quality, bioactive stability, and sensory acceptability of two BRB delivery systems of various matrices are presented. BRB dosage, pH, water activity, and texture were consistent in the scale-up production. Confections retained >90% of anthocyanins and ellagitannin after processing. Nectars had >69% of anthocyanins and >66% of ellagitannin retention, which varied with BRB dosage due to the processing difference. Texture remained unchanged during storage. BRB products consumed in a prostate cancer clinical trial were well accepted in sensory tests. Thus, this study demonstrates that two different BRB foods can be formulated to meet quality standards with a consistent bioactive pattern and successfully scaled up for a large human clinical trial focusing on cancer risk and other health outcomes.

    Physiological instability leading to clinical deterioration often precedes cardiopulmonary arrest. Nurses, who have the most frequent patient contact and responsibility for ongoing monitoring of patients, play a crucial role in recognizing and responding to clinical deterioration. The importance of education in supporting such a role has been addressed in numerous studies. This study aimed to identify nurses' educational needs and explore educational strategies to enhance their ability in recognizing and managing wards with deteriorating patients. A literature search from databases (2000-2010) was undertaken to include papers that identified the educational needs of ward nurses and existing educational programmes related to the care of deteriorating patients. Twenty-six papers were included in this review. Findings identified the educational need to empower nurses with the appropriate knowledge and skills in recognizing, reporting and responding to patient deterioration. The review of existing educational programmes and their outcomes identified valuable teaching information and strategies, and areas that could be improved in meeting nurses' educational needs. The review has highlighted important aspects of patient safety in clinical deterioration that could be further addressed by educational strategies targeting the role of ward nurses. These strategies include: utilizing clinical decision-making models to develop nurses' decision making skills; developing a standardized tool for systematic nursing assessment and management of clinical deterioration; incorporating training in clinical deterioration as a core competence of pre-registered nursing education; providing vital signs training to nursing assistants; and conducting more rigorous studies to evaluate the effectiveness of the educational programmes. © 2011 The Authors.

    Numerous reports indicate that the incidence of posttraumatic stress disorder (PTSD) in Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) military personnel has created a significant behavioural healthcare challenge. These findings have served to motivate research on how to better develop and disseminate evidence-based treatments for PTSD. The current article presents the use of Virtual Reality (VR) as a clinical tool to address the assessment, prevention, and treatment of PTSD, based on the VR projects that were evolved at the University of Southern California Institute for Creative Technologies since 2004. A brief discussion of the definition and rationale for the clinical use of VR is followed by a description of a VR application designed for the delivery of prolonged exposure (PE) for treating Service Members (SMs) and Veterans with combat- and sexual assault-related PTSD. The expansion of the virtual treatment simulations of Iraq and Afghanistan for PTSD assessment and prevention is then presented. This is followed by a forward-looking discussion that details early efforts to develop virtual human agent systems that serve the role of virtual patients for training the next generation of clinical providers, as healthcare guides that can be used to support anonymous access to trauma-relevant behavioural healthcare information, and as clinical interviewers capable of automated behaviour analysis of users to infer psychological state. The paper will conclude with a discussion of VR as a tool for breaking down barriers to care in addition to its direct application in assessment and intervention.

    The goal of this study is the creation and use of a five-stage scale for the description of the health status of a type 2 diabetes mellitus patient population, as individuals and as a set. The scale, named UISESS, ranges from the pre-pathological to the sequelae stage, and can help orient multidisciplinary prevention actions. SETTING AND SAMPLING: A sample of nondiabetics (n = 404), together with a census of all type 2 diabetic patients (n = 2,702) over 30 years of age, were obtained from a family medicine clinic of the Mexican Federal Social Security System (IMSS) in Guadalajara, Mexico. A descriptive study in which the Natural History of the Disease and an epidemiological focus on risk were used to create the UISESS scale. Case histories of a total of 3,106 persons from a family practice clinic were used. The data was classified in five stages and three risk control levels were used for analysis. In the type 2 diabetic group, the average age was 57.6 years; 58% were women. In the nondiabetic group, the average age was 55.38 years; 63% were women. The UISESS scale was applied. A large majority (86%) of the studied type 2 diabetic patients were classified within unfavorable stages for controlling their illness, and 65% of the 3,106 people were at high or very high risk of increasing deterioration of their health status. The UISESS scale appears to be a useful tool to detect the distribution, evolution and control of type 2 diabetes in a population attended at the outpatient clinic of a family medicine unit, according to the Natural History of the Disease.

    Hospitalized medical and surgical patients encompass a group of patients in whom venous thromboembolism (VTE) poses a major concern on morbidity and mortality. Recently, direct oral anticoagulants for the prevention of VTE have been developed to overcome the drawbacks of the food/drug interactions and the need for frequent laboratory monitoring and dose adjustments associated with the use of vitamin K antagonists and the inconvenience of the subcutaneous administration of low-molecular-weight heparins and fondaparinux. The novel oral anticoagulants that have been tested in major clinical trials for VTE prevention in medical and surgical patients are the thrombin inhibitor dabigatran and the factor Xa inhibitors apixaban, rivaroxaban, and edoxaban, which will be the focus of this review. While the new drugs proved to be highly effective and safe in the prevention of VTE following major orthopedic surgery, they failed to show a favorable benefit-to-risk profile in hospitalized medical patients receiving extended anticoagulation beyond the hospital stay.

    To identify the clinical empirical evidence for identifying, managing and preventing skin maceration in human subjects. A rapid review of the current literature was undertaken between 5 September and 19 September 2016 using the electronic databases CINAHL, MEDLINE, PUBMED and Cochrane, with the key words: skin macerat*, wound macerat*, moisture associated skin damage, wound exudate and hyper-hydration of skin, Results: Of 526 papers found using an electronic database search, four were identified as fitting the search parameters, and a further two were retrieved from a manual search of reference lists. There were three themes that emerged: how to identify and measure maceration, how to manage and reduce maceration once it has already occurred, and how to prevent skin maceration. Hyper-hydration can reach greater skin depths than previously thought, thus engendering more extensive damage potential, which in turn can impact on treatments and healing time. Realistically, the deeper the hyper-hydration issue, the more extensive the damage and it will take longer to recover-a problem compounded if the hyper-hydration is due to incontinence and skin is also exposed to urine and/or faeces. In relation to wound management, the authors advocate the removal of moisture away from the wound or skin, either through superabsorbent dressings, or by allowing the excess moisture to evaporate through semi-permeable dressings to reduce maceration, enhance patient comfort and encourage healing. However, we found no evidence regarding the limits of hydration of the dermis and epidermis and thereby the optimal conditions for managing exuding wounds and promoting skin health. Each of the six papers in this review calls for further research to help identify, treat and prevent maceration. Maceration causes patients' discomfort and pain as well as prolonging healing time and deserves more focused research. This rapid review highlights how limited the clinical empirical research is on

    Dental Therapists and Oral Health Therapists (Therapists) working in the New South Wales (NSW) Public Oral Health Service are charged with providing clinical dental treatment including preventive care for all children under 18 years of age. Adolescents in particular are at risk of dental caries and periodontal disease which may be controlled through health education and clinical preventive interventions. However, there is a dearth of evidence about the type or the proportion of clinical time allocated to preventive care.The aim of this study is to record the proportion and type of preventive care and clinical treatment activities provided by Therapists to adolescents accessing the NSW Public Oral Health Service. Clinical dental activity data for adolescents was obtained from the NSW Health electronic Information System for Oral Health (ISOH) for the year 2011. Clinical activities of Therapists were examined in relation to the provision of different types of preventive care for adolescents by interrogating state-wide public oral health data stored on ISOH. Therapists were responsible for 79.7 percent of the preventive care and 83.0 percent of the restorative treatment offered to adolescents accessing Public Oral Health Services over the one year period. Preventive care provided by Therapists for adolescents varied across Local Health Districts ranging from 32.0 percent to 55.8 percent of their clinical activity. Therapists provided the majority of clinical care to adolescents accessing NSW Public Oral Health Services. The proportion of time spent undertaking prevention varied widely between Local Health Districts. The reasons for this variation require further investigation.

    To explore the characteristics of and interactions between clinicians, patients and family members during management of the deteriorating adult patient in the emergency department. Previous research into family presence during resuscitation has identified many positive outcomes when families are included. However, over the last three decades the epidemiology of acute clinical deterioration has changed, with a decrease in in-hospital cardiac arrests and an increase in acute clinical deterioration. Despite the decrease in cardiac arrests, research related to family presence continues to focus on care during resuscitation rather than care during acute deterioration. Descriptive exploratory study using nonparticipatory observation. Five clinical deterioration episodes were observed within a 50-bed, urban, Australian emergency department. Field notes were taken using a semistructured tool to allow for thematic analysis. Presence, roles and engagement describe the interactions between clinicians, family members and patients while family are present during a patient's episode of deterioration. Presence was classified as no presence, physical presence and therapeutic presence. Clinicians and family members moved through primary, secondary and tertiary roles during patients' deterioration episode. Engagement was observed to be superficial or deep. There was a complex interplay between presence, roles and engagement with each influencing which form the other could take. Current practices of managing family during episodes of acute deterioration are complex and multifaceted. There is fluid interplay between presence, roles and engagement during a patient's episode of deterioration. This study will contribute to best practice, provide a strong foundation for clinician education and present opportunities for future research. © 2017 John Wiley & Sons Ltd.

    Full Text Available Background: The Mahalapye district health management team (DHMT conducts regular audits to evaluate the standard of services delivered to patients, one of which is the prevention of mother-to-child-transmission (PMTCT programme. Xhosa clinic is one of the facilities in Mahalapye which provides a PMTCT programme.Aim: This audit aimed to identify gaps between the current PMTCT clinical practice in Xhosa clinic and the Botswana PMTCT national guidelines.Setting: This audit took place in Xhosa clinic in the urban village of Mahalapye, in the Central District of Botswana.Methods: This was a retrospective audit using PMTCT Xhosa clinic records of pregnant mothers and HIV-exposed babies seen from January 2013 to June 2013.Results: One hundred and thirty-three pregnant women registered for antenatal care. Twenty-five (19% knew their HIV-positive status as they had been tested before their pregnancy or had tested HIV positive at their first antenatal clinic visit. More than two-thirds of the 115 pregnant women (69% were seen at a gestational age of between 14 and 28 weeks. About two-thirds of the pregnant women (67% took antiretroviral drugs. Of the 44 HIV-exposed infants, 39 (89% were HIV DNA PCR negative at 6 weeks. Thirty-two (73% children were given cotrimoxazole prophylaxis between 6 and 8 weeks.Conclusion: The PMTCT programme service delivery was still suboptimal and could potentially increase the mother-to-child transmission of HIV. Daily monitoring mechanism to track those eligible could help to close the gap.

    A randomised trial of nurse-led secondary prevention clinics for coronary heart disease resulted in improved secondary prevention and significantly lowered all-cause mortality at 4-year follow-up. This qualitative trial was conducted to explore the experience of health professionals that had been involved in running the clinics. To identify the barriers and facilitators to establishing secondary prevention clinics for coronary heart disease within primary care. Semi-structured audiotaped telephone interviews with GPs and nurses involved in running clinics. A stratified, random sample of 19 urban, suburban, and rural general practices in north-east Scotland. Semi-structured telephone interviews with 19 GPs and 17 practice-based nurses involved in running nurse-led clinics for the secondary prevention of coronary heart disease. Eight practices had run clinics continuously and 11 had stopped, with eight subsequently restarting. Participants accounted for these patterns by referring to advantages and disadvantages of the clinics in four areas: patient care, development of nursing skills, team working, and infrastructure. Most practitioners perceived benefits for patients from attending secondary prevention clinics, but some, from small rural practices, thought they were unnecessary. The extended role for nurses was welcomed, but was dependent on motivated staff, appropriate training and support. Clinics relied on, and could enhance, team working, however, some doctors were wary of delegating. With regard to infrastructure, staff shortages (especially nurses) and accommodation were as problematic as lack of funds. Nurse-led secondary prevention clinics were viewed positively by most healthcare professionals that had been involved in running them, but barriers to their implementation had led most to stop running them at some point. Lack of space and staff shortages are likely to remain ongoing problems, but improvements in funding training and communication within

    HIV-1 sequencing has been used extensively in epidemiologic and forensic studies to investigate patterns of HIV-1 transmission. However, the criteria for establishing genetic linkage between HIV-1 strains in HIV-1 prevention trials have not been formalized. The Partners in Prevention HSV/HIV Transmission Study (ClinicaITrials.gov NCT00194519) enrolled 3408 HIV-1 serodiscordant heterosexual African couples to determine the efficacy of genital herpes suppression with acyclovir in reducing HIV-1 transmission. The trial analysis required laboratory confirmation of HIV-1 linkage between enrolled partners in couples in which seroconversion occurred. Here we describe the process and results from HIV-1 sequencing studies used to perform transmission linkage determination in this clinical trial. Consensus Sanger sequencing of env (C2-V3-C3) and gag (p17-p24) genes was performed on plasma HIV-1 RNA from both partners within 3 months of seroconversion; env single molecule or pyrosequencing was also performed in some cases. For linkage, we required monophyletic clustering between HIV-1 sequences in the transmitting and seroconverting partners, and developed a Bayesian algorithm using genetic distances to evaluate the posterior probability of linkage of participants sequences. Adjudicators classified transmissions as linked, unlinked, or indeterminate. Among 151 seroconversion events, we found 108 (71.5%) linked, 40 (26.5%) unlinked, and 3 (2.0%) to have indeterminate transmissions. Nine (8.3%) were linked by consensus gag sequencing only and 8 (7.4%) required deep sequencing of env. In this first use of HIV-1 sequencing to establish endpoints in a large clinical trial, more than one-fourth of transmissions were unlinked to the enrolled partner, illustrating the relevance of these methods in the design of future HIV-1 prevention trials in serodiscordant couples. A hierarchy of sequencing techniques, analysis methods, and expert adjudication contributed to the linkage

    Human cytomegalovirus (CMV) is under-recognised, despite being the leading infectious cause of congenital malformation, affecting ~0.3% of Australian live births. Approximately 11% of infants born with congenital CMV infection are symptomatic, resulting in clinical manifestations, including jaundice, hepatosplenomegaly, petechiae, microcephaly, intrauterine growth restriction and death. Congenital CMV infection may cause severe long-term sequelae, including progressive sensorineural hearing loss and developmental delay in 40-58% of symptomatic neonates, and ~14% of initially asymptomatic infected neonates. Up to 50% of maternal CMV infections have nonspecific clinical manifestations, and most remain undetected unless specific serological testing is undertaken. The combination of serology tests for CMV-specific IgM, IgG and IgG avidity provide improved distinction between primary and secondary maternal infections. In pregnancies with confirmed primary maternal CMV infection, amniocentesis with CMV-PCR performed on amniotic fluid, undertaken after 21-22 weeks gestation, may determine whether maternofetal virus transmission has occurred. Ultrasound and, to a lesser extent, magnetic resonance imaging are valuable tools to assess fetal structural and growth abnormalities, although the absence of fetal abnormalities does not exclude fetal damage. Diagnosis of congenital CMV infection at birth or in the first 3 weeks of an infant's life is crucial, as this should prompt interventions for prevention of delayed-onset hearing loss and neurodevelopmental delay in affected infants. Prevention strategies should also target mothers because increased awareness and hygiene measures may reduce maternal infection. Recognition of the importance of CMV in pregnancy and in neonates is increasingly needed, particularly as therapeutic and preventive interventions expand for this serious problem. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Full Text Available Characterization of viruses in HIV-1 transmission pairs will help identify biological determinants of infectiousness and evaluate candidate interventions to reduce transmission. Although HIV-1 sequencing is frequently used to substantiate linkage between newly HIV-1 infected individuals and their sexual partners in epidemiologic and forensic studies, viral sequencing is seldom applied in HIV-1 prevention trials. The Partners in Prevention HSV/HIV Transmission Study (ClinicalTrials.gov #NCT00194519 was a prospective randomized placebo-controlled trial that enrolled serodiscordant heterosexual couples to determine the efficacy of genital herpes suppression in reducing HIV-1 transmission; as part of the study analysis, HIV-1 sequences were examined for genetic linkage between seroconverters and their enrolled partners.We obtained partial consensus HIV-1 env and gag sequences from blood plasma for 151 transmission pairs and performed deep sequencing of env in some cases. We analyzed sequences with phylogenetic techniques and developed a Bayesian algorithm to evaluate the probability of linkage. For linkage, we required monophyletic clustering between enrolled partners' sequences and a Bayesian posterior probability of ≥ 50%. Adjudicators classified each seroconversion, finding 108 (71.5% linked, 40 (26.5% unlinked, and 3 (2.0% indeterminate transmissions, with linkage determined by consensus env sequencing in 91 (84%. Male seroconverters had a higher frequency of unlinked transmissions than female seroconverters. The likelihood of transmission from the enrolled partner was related to time on study, with increasing numbers of unlinked transmissions occurring after longer observation periods. Finally, baseline viral load was found to be significantly higher among linked transmitters.In this first use of HIV-1 sequencing to establish endpoints in a large clinical trial, more than one-fourth of transmissions were unlinked to the enrolled partner

    Factors predisposing hormone-dependent tissues to the development of tumors coincide, at least partly, with hormonal-metabolic promoters (like insulin resistance, glucose intolerance, visceral obesity, etc.) of other main non-communicable diseases. This important knowledge poses the question of whether the same approach which is applied for prevention/treatment of a metabolic syndrome and the associated endocrine disorders might also be used in preventive and therapeutic oncology. Whereas an answer to this question remains controversial and is based mainly on experimental evidence, there is accumulating clinical data suggesting a practical significance of such a strategy, even though it is not to be considered as directly cytostatic. Among the many drugs under discussion, three groups of medicines (statins, antidiabetic biguanides, and thiazolidinediones) are the most attractive. The concept of metabolic rehabilitation is proposed and used practically in an adjuvant setting for the correction of the above-mentioned endocrine-metabolic disorders commonly found in cancer patients. The current use and aim of this approach is to improve the survival of patients and limit cancer progression. Nonetheless, it also appears potentially useful as a neoadjuvant therapy as well as a prophylactic treatment earlier in life for specific groups of people with hormone-associated enhanced oncological risk. It seems possible that certain hypolipidemic and antidiabetic medicines with pleiotropic effects might be combined with traditional antisteroid prevention/therapeutic approaches in routine clinical situations as well as for overcoming resistance to standard cancer hormonal therapies including receptor-negative cases. Characteristic at the end of the 20th and at the beginning of the 21st century is an epidemic of diabetes and obesity, which might further increase the incidence of certain cancers. This makes it timely to apply hypolipidemic and antidiabetic drugs (in combination

    The risk of post-traumatic osteoarthritis (PTOA) substantially increases following joint injury. Research efforts should focus on investigating the efficacy of preventative strategies in high quality randomized controlled trials (RCT). The objective of these OARSI RCT recommendations is to inform the design, conduct and analytical approaches to RCTs evaluating the preventative effect of joint injury prevention strategies. Recommendations regarding the design, conduct, and reporting of RCTs evaluating injury prevention interventions were established based on the consensus of nine researchers internationally with expertise in epidemiology, injury prevention and/or osteoarthritis (OA). Input and resultant consensus was established through teleconference, face to face and email correspondence over a 1 year period. Recommendations for injury prevention RCTs include context specific considerations regarding the research question, research design, study participants, randomization, baseline characteristics, intervention, outcome measurement, analysis, implementation, cost evaluation, reporting and future considerations including the impact on development of PTOA. Methodological recommendations for injury prevention RCTs are critical to informing evidence-based practice and policy decisions in health care, public health and the community. Recommendations regarding the interpretation and conduct of injury prevention RCTs will inform the highest level of evidence in the field. These recommendations will facilitate between study comparisons to inform best practice in injury prevention that will have the greatest public health impact.

    Hospital stays for patients with pressure ulcers (PU) increased nearly 80% from 1992 to 2006. Most PU's developed during an admission, often despite preventive efforts from clinical staff. Data from Electronic medical records (EMR's) were used to prepare daily patient risk factor and PU information for nurses to help prevent PU development and exacerbations. THE OBJECTIVES OF THIS STUDY WERE TO DETERMINE WHETHER: 1) dissemination of an automated daily report with patient risk and current status of pressure ulcers ("PU Daily") helps prevent the development of pressure ulcers, and 2) using the PU Daily information impacts the severity of pressure ulcers that develop in an acute care setting. A pre-post study with four control units was designed to determine the impact of the PU Daily in intensive care units (ICU) in a large medical center. The control units included ICU's using the same EMR and similar complexity of cases with a high risk of developing a PU. The pre-post study took place over a six month period (March - August 2009). A total of 6,735 cases were included in the study. The intervention unit showed a significant decrease (p = 0.004) in PU's at post-evaluation; none of the four comparison units showed a decrease at the pintervention led to a significant reduction in the total number of PU's documented (p intervention with the PU Daily showed a significant decrease in the total PU's and severity of PU's and allowed for implementation of interventions that help prevent the development of PU's. As EMR's become more widely available, this intervention showed a reduction in PU's. Future studies should further develop this intervention and include multiple institutions and patient populations.

    To evaluate the quality of clinical practice guidelines (CPGs) for dental caries prevention in children and adolescents MATERIALS AND METHODS: We performed a systematic search of CPGs on caries preventive measures between 2005 and 2016. We searched MEDLINE, EMBASE, LILACS, TripDatabase, websites of CPG developers, compilers of CPGs, scientific societies and ministries of health. We included CPGs with recommendations on sealants, fluorides and oral hygiene. Three reviewers independently assessed the included CPGs using the AGREE II instrument. We calculated the standardised scores for the six domains and made a final recommendation about each CPG. Also, we calculated the overall agreement among calibrated reviewers with the intraclass correlation coefficient (ICC). Twenty-two CPGs published were selected from a total of 637 references. Thirteen were in English and nine in Spanish. The overall agreement between reviewers was very good (ICC = 0.90; 95%CI 0.89-0.92). The mean score for each domain was the following: Scope and purpose 89.6 ± 12%; Stakeholder involvement 55.0 ± 15.6%; Rigour of development 64.9 ± 21.2%; Clarity of presentation 84.8 ± 14.1%; Applicability 30.6 ± 31.5% and Editorial independence 59.3 ± 25.5%. Thirteen CPGs (59.1%) were assessed as "recommended", eight (36.4%) "recommended with modifications" and one (4.5%) "not recommended". The overall quality of CPGs in caries prevention was moderate. The domains with greater deficiencies were Applicability, Stakeholder involvement and Editorial independence. Clinicians should use the best available CPGs in dental caries prevention to provide optimal oral health care to patients.

    Psychological treatments can relieve mental distress and improve well-being, and the dissemination of evidence-based methods can help patients gain access to the right type of aid. Meanwhile, Internet-based cognitive-behavioral therapy (ICBT) has shown promising results for many psychiatric disorders. However, research on the potential for negative effects of psychological treatments has been lacking. An individual patient data meta-analysis of 29 clinical trials of ICBT (N = 2,866) was performed using the Reliable Change Index for each primary outcome measures to distinguish deterioration rates among patients in treatment and control conditions. Statistical analyses of predictors were conducted using generalized linear mixed models. Missing data was handled by multiple imputation. Deterioration rates were 122 (5.8%) in treatment and 130 (17.4%) in control conditions. Relative to receiving treatment, patients in a control condition had higher odds of deteriorating, odds ratios (ORs) = 3.10, 95% confidence interval (CI) [2.21, 4.34]. Clinical severity at pretreatment was related to lower odds, OR = 0.62, 95% CI [0.50, 0.77], and OR = 0.51, 95% CI [0.51, 0.80], for treatment and control conditions. In terms of sociodemographic variables, being in a relationship, OR = 0.58, 95% CI [0.35, 0.95], having at least a university degree, OR = 0.54, 95% CI [0.33, 0.88], and being older, OR = 0.78, 95% CI, [0.62, 0.98], were also associated with lower odds of deterioration, but only for patients assigned to a treatment condition. Deterioration among patients receiving ICBT or being in a control condition can occur and should be monitored by researchers to reverse and prevent a negative treatment trend.

    Hospital quality and financial sustainability rely on reducing healthcare-associated events/infections, length of stay, and readmissions. This project focused on designing an integrated role for the clinical nurse specialist (CNS) and the infection prevention professional (IPP) to proactively manage the delivery of evidence-based practice to high-risk surgical patients. The healthcare industry is in the midst of a paradigm shift driven by changing health policy focusing on quality indicators, patient satisfaction, and lowering costs. Coupled with these indicators is the expectation and responsibility to provide evidence-based practice at all levels of the healthcare continuum. This paradigm shift places healthcare facilities in a very competitive atmosphere as they rally for the revenue of a fixed payer mix. A literature search using CINHAL, PubMed, and the CNS national listserve databases was completed to identify if there was any previously written information available on an integrated role of the CNS/IPP. An online business plan template was used to communicate the significance, implications, and return on organizational investment to practice with establishing this role. Chronic health conditions such as diabetes, hypertension, congestive heart failure, and colonization with multidrug-resistant organisms can place patients at an increased risk for developing a surgical site infection or complications. The CNS/IPP will proactively manage these risk factors, including the patient and family in a preventive care model to manage the acute inpatient high-risk surgical patient. Care management will include coordinated, collaborative, and consultative follow-up by the CNS/IPP in the acute care, long-term care facilities, and home settings. The infection prevention skill set brings a level of clinical expertise that makes a unique CNS. The IPP is immersed in using epidemiological principles that examine the impact of comorbidities and the added risk that can

    Suicide-preventive training has shown to influence attitudes. This study aimed at investigating what impact other factors than knowledge might have on attitudes towards work with suicidal patients and suicide prevention. In 2007, 500 health-care staff working in a psychiatric clinic in Stockholm received a questionnaire with items concerning work with suicidal patients to which 358 (71.6%) responded. A set of attitude items were tested using structural equation modelling (LISREL). Three models were found to be satisfactory valid and reliable: Job clarity, Job confidence and Attitudes towards prevention. These were then used in regression analyses as dependent variables with predictors such as experience of work with suicidal patients, perceived sufficient training, age and gender. Perceived sufficient training was consistently the most important predictor for all three attitude concepts (p prevention). Age was another significant predictor for Job clarity (p suicide for Job confidence (p suicide preventive education is likely to improve attitudes towards the prevention of suicide, clarity and confidence regarding their role in the care for suicidal patients. These improvements may contribute to the prevention of suicide in health care settings.

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

    Advertising via Facebook to elicit involvement in clinical trials has demonstrated promise in expanding geographic reach while maintaining confidentiality. The purpose of this study is to evaluate Facebook advertising to reach at-risk, predominately African American or Black women in higher HIV prevalence communities for an HIV prevention clinical trial, and to compare baseline characteristics to those recruited on-the-ground. Maintaining confidentiality and the practical aspects of creating and posting ads on Facebook are described. The advertising strategy targeted multicultural affinities, gender, age, interest terms, and zip codes. We report on results during 205 days. A total of 516,498 Facebook users viewed the ads an average of four times, resulting in 37,133 clicks to the study website. Compared to 495 screened on-the-ground, 940 were screened via Facebook ads, of these, half (n = 477, 50.74%) were high risk, and of those at risk, 154 were randomized into the 6-month clinical trial. Black women comprised 71.60% (n = 673) of the total screened online. Roughly twice as many Black women screened via Facebook compared to on-the-ground, yet, the percentage at high risk was similar. Preliminary data suggest that the extent to which ad headlines and photos tap into authentic social experience, advertising on Facebook can extend geographic reach and provide a comparative sample to women recruited on-the-ground.

  12. Prevention of ventilator-associated pneumonia in the intensive care unit: A review of the clinically relevant recent advancements

    Full Text Available Ventilator-associated pneumonia (VAP is one of the most commonly encountered hospital-acquired infections in intensive care units and is associated with significant morbidity and high costs of care. The pathophysiology, epidemiology, treatment and prevention of VAP have been extensively studied for decades, but a clear prevention strategy has not yet emerged. In this article we will review recent literature pertaining to evidence-based VAP-prevention strategies that have resulted in clinically relevant outcomes. A multidisciplinary strategy for prevention of VAP is recommended. Those interventions that have been shown to have a clinical impact include the following: (i Non-invasive positive pressure ventilation for able patients, especially in immunocompromised patients, with acute exacerbation of chronic obstructive pulmonary disease or pulmonary oedema, (ii Sedation and weaning protocols for those patients who do require mechanical ventilation, (iii Mechanical ventilation protocols including head of bed elevation above 30 degrees and oral care, and (iv Removal of subglottic secretions. Other interventions, such as selective digestive tract decontamination, selective oropharyngeal decontamination and antimicrobial-coated endotracheal tubes, have been tested in different studies. However, the evidence for the efficacy of these measures to reduce VAP rates is not strong enough to recommend their use in clinical practice. In numerous studies, the implementation of VAP prevention bundles to clinical practice was associated with a significant reduction in VAP rates. Future research that considers clinical outcomes as primary endpoints will hopefully result in more detailed prevention strategies.

    2011-09-01

    The purpose of this review is to summarize the most important human clinical trials of antioxidants as cancer prevention agents conducted to date, provide an overview of currently ongoing studies, and discuss future steps needed to advance research in this field. To date there have been several large (at least 7000 participants) trials testing the efficacy of antioxidant supplements in preventing cancer. The specific agents (diet-derived direct antioxidants and essential components of antioxidant enzymes) tested in those trials included β-carotene, vitamin E, vitamin C, selenium, retinol, zinc, riboflavin, and molybdenum. None of the completed trials produced convincing evidence to justify the use of traditional antioxidant-related vitamins or minerals for cancer prevention. Our search of ongoing trials identified six projects at various stages of completion. Five of those six trials use selenium as the intervention of interest delivered either alone or in combination with other agents. The lack of success to date can be explained by a variety of factors that need to be considered in the next generation research. These factors include lack of good biological rationale for selecting specific agents of interest; limited number of agents tested to date; use of pharmacological, rather than dietary, doses; and insufficient duration of intervention and follow-up. The latter consideration underscores the need for alternative endpoints that are associated with increased risk of neoplasia (i.e., biomarkers of risk), but are detectable prior to tumor occurrence. Although dietary antioxidants are a large and diverse group of compounds, only a small proportion of candidate agents have been tested. In summary, the strategy of focusing on large high-budget studies using cancer incidence as the endpoint and testing a relatively limited number of antioxidant agents has been largely unsuccessful. This lack of success in previous trials should not preclude us from seeking novel

    This study aims to describe adherence to seven clinical preventive services among Spanish adults with diabetes, to compare adherence with people without diabetes and to identify predictor of adherence to multiple practices among adults with diabetes. Cross-sectional study based on data obtained from the European Health Survey for Spain 2009 and the Spanish National Health Survey 2011. We analyzed those aged 40-69 years (n= 20,948). Diabetes status was self-reported. The study variables included adherence to blood pressure (BP) checkup, cholesterol measurement, influenza vaccination, dental examination, fecal occult blood test (FOBT), mammography and cytology. Independent variables included socio-demographic characteristics, variables related to health status and lifestyle factors. The study sample included 1,647 subjects with diabetes and 19,301 without. Over 90% had measured their BP and cholesterol in the last year, 44.4% received influenza immunization, 36.4% had a dental checkup within the year and only 8.1% underwent a FOBT. Among diabetic women 75.4% had received a mammography and 52.4% a cytology in the recommended periods. The adherence to BP and cholesterol measurements and influenza vaccination was significantly higher among those suffering diabetes and cytology and dental checkup were lower. Only 63.4% of people with diabetes had fulfilled half or more of the recommended practices. Female sex, higher educational level, being married or cohabiting, higher number of chronic conditions and number of physician visits increased the adherence to multiple preventive practices. For each unhealthy lifestyle reported the probability of having a higher adherence level decreased. Acceptable adherence is found for BP and cholesterol checkups and mammography.

    Curcumin derived from turmeric is well documented for its anti-carcinogenic, antioxidant and anti-inflammatory properties. Recent studies show that curcumin also possesses neuroprotective and cognitive-enhancing properties that may help delay or prevent neurodegenerative diseases, including Alzheimer's disease (AD). Currently, clinical diagnosis of AD is onerous, and it is primarily based on the exclusion of other causes of dementia. In addition, phase III clinical trials of potential treatments have mostly failed, leaving disease-modifying interventions elusive. AD can be characterised neuropathologically by the deposition of extracellular β amyloid (Aβ) plaques and intracellular accumulation of tau-containing neurofibrillary tangles. Disruptions in Aβ metabolism/clearance contribute to AD pathogenesis. In vitro studies have shown that Aβ metabolism is altered by curcumin, and animal studies report that curcumin may influence brain function and the development of dementia, because of its antioxidant and anti-inflammatory properties, as well as its ability to influence Aβ metabolism. However, clinical studies of curcumin have revealed limited effects to date, most likely because of curcumin's relatively low solubility and bioavailability, and because of selection of cohorts with diagnosed AD, in whom there is already major neuropathology. However, the fresh approach of targeting early AD pathology (by treating healthy, pre-clinical and mild cognitive impairment-stage cohorts) combined with new curcumin formulations that increase bioavailability is renewing optimism concerning curcumin-based therapy. The aim of this paper is to review the current evidence supporting an association between curcumin and modulation of AD pathology, including in vitro and in vivo studies. We also review the use of curcumin in emerging retinal imaging technology, as a fluorochrome for AD diagnostics.

    Maisonneuve, H

    1996-01-01

    The aim of this article is to present the findings concerning scientific fraud that have appeared in case reports. Deliberate scientific fraud does exist. The fact that most of the documented cases have occurred in Anglo-Saxon countries seems to indicate, not that Anglo-Saxons are more prone to scientific fraud, but rather that they have been more successful in bringing it to light. Since 1974, 72 cases have been reported in which there was either conclusive evidence or else a strong presumption of fraud: one case in Switzerland, one in Canada, four in Australia, 14 in Great Britain and 52 in the United States. Fraud is estimated to affect 2-5% of clinical research trials. Referees and readers do not set out to track fraud. The American Commission has proposed the terms "misappropriation, interference, misrepresentation" to define fraud. Voluntary fraud is hidden and its detection delayed. In well-known cases, more than 5 years elapsed before the information reached the scientific community. Whistle blowers must sustain a determined effort to denounce fraud over a period of 1-3 years if they are to trigger an investigation. Some whistle blowers have themselves been accused of fraud because their claims proved so embarrassing. Fraud can lead to severe accidents and generate expenditure that those responsible, or the institutions they work for, will never pay back. Frauders are usually motivated by the desire for material gain or the desire to become well-known. The motivating factor may be personal enrichment, or a need for funds for a not-for-profit association. People found guilt of fraud always have good excuses. Some simply do not realize what they have done. A knowledge of research methodology and critical appraisal methods can help to prevent fraud. Good clinical, laboratory and manufacturing practice can help to prevent misconduct and trickery. Audits and inspections are another essential means of combatting fraud.

    We report on a rare case of cochlear implantation in a patient affected by relapsing polychondritis (RP), which over time induced cochlear fibrosis/ossification and deterioration of previously excellent hearing performance. The clinical course was determined by CT scan, electrophysiology, and speech perception data. We conclude that RP is a severe autoimmune connective disorder that can cause profound sensorineural hearing loss. Cochlear implantation in these patients can provide excellent performance. Continuation of therapy may improve prognosis, but relapses involving inner ear structures can determine fibrosis/ossification of the modiolus and interfere with cochlear implant use.

    The purpose of this project was to implement clinic system changes that support evidence-based guidelines for childhood obesity prevention. Adherence rates for prevention and screening of children in a rural Midwest primary care setting were used to measure the success of the program. Retrospective chart reviews reflected gaps in current practice and documentation. An evidence-based toolkit for childhood obesity prevention was used to implement clinic system changes for the identified gaps. The quality improvement approach proved to be effective in translating knowledge of obesity prevention guidelines into rural clinic practices with significant improvements in documentation of prevention measures that may positively impact the childhood obesity epidemic. Primary care providers, including nurse practitioners (NPs), are at the forefront of diagnosing, educating, and counseling children and families on obesity prevention and need appropriate resources and tools to deliver premier care. The program successfully demonstrated how barriers to practice, even with the unique challenges in a rural setting, can be overcome. NPs fulfill a pivotal primary care role and can provide leadership that may positively impact obesity prevention in their communities. ©2015 American Association of Nurse Practitioners.

    The incidence of hearing loss has risen in past years. Attendance at music festivals and concerts may contribute to this increasing problem. To assess the effectiveness of earplugs in preventing temporary hearing loss immediately following music exposure. A randomized, single-blind clinical trial was conducted on September 5, 2015, at an outdoor music festival in Amsterdam, the Netherlands. Normal-hearing adult volunteers were recruited via social media. An exclusion criterion was the participants' intention to wear earplugs. Of the 86 volunteers assessed, 51 were included in the study. All analyses were performed on an intention-to-treat basis. Participants were randomly assigned to a group using earplugs or an unprotected group during a 4½-hour festival visit. The primary study outcome was a temporary threshold shift (TTS) on the audiogram, primarily for frequencies at 3 and 4 kHz. Secondary study outcomes included distortion product otoacoustic emission (DPOAE) measurements and claims of tinnitus using a questionnaire and tinnitus matching experiments. Of 51 participants included, 25 were randomized to the earplug group and 26 to the unprotected group. Nine in each group (36% and 35%, respectively) were men, and the mean (SD) ages were 27.3 (5.6) years in the earplug group and 27.0 (6.2) years in the unprotected group. Baseline demographics were similar in both groups. The time-averaged, equivalent A-weighted sound pressure level experienced was 100 dBA during the festival. A TTS over frequencies at 3 and 4 kHz after exposure was seen in 4 of 50 ears (8%) in the earplug group compared with 22 of 52 ears (42%) in the unprotected group (P preventing 1 TTS was 2.9. The DPOAE amplitudes decreased significantly more over the frequencies 2 to 8 kHz in the unprotected group: the mean (SD) decrease in magnitude was 0.6 (2.8) dB in the earplug group vs 2.2 (1.9) dB in the unprotected group (P = .04). Newly induced tinnitus following sound exposure occurred in 3 of

    Low-income and minority mothers experience a disproportionate incidence of depression and lack access to treatment services. Development of prevention strategies in accessible community-based venues is a potentially important public health strategy. To determine the efficacy of a depression prevention strategy embedded in Head Start. This randomized clinical trial was performed from February 15, 2011, through May 9, 2016, at 6 Head Start agencies serving families at or below the federal poverty level. Participants included mothers with depressed mood, anhedonia, or depression history but who were not in a current major depressive episode. Participants were followed up for 12 months with masked outcome assessments. Final follow-up was completed on May 9, 2016. Participants were randomized to a problem-solving education (PSE) intervention (n = 111) or usual Head Start services (n = 119). Primary outcomes were problem-solving skills and depressive symptoms. To capture the chronicity and intensity of symptoms, the Quick Inventory of Depressive Symptoms was administered bimonthly, and rates of clinically significant symptom elevations were compared across groups. Secondarily, the presence of a major depressive episode was assessed using the Structured Clinical Interview for DSM-IV Axis I Disorders. Among the 230 participants, 152 (66.1%) were Hispanic, with a mean (SD) age of 31.4 (7.3) years. An intention-to-treat analysis among 223 participants contributing follow-up data found no differences in problem-solving skills across groups. The mean (SD) number of depressive symptom elevations among the PSE participants was 0.84 (1.39) compared with 1.12 (1.47) among the usual service participants (adjusted incident rate ratio [aIRR], 0.60; 95% CI, 0.41-0.90). In analyses stratified according to baseline depressive symptoms, PSE exerted a preventive effect among those with lower-level baseline symptoms, with a mean (SD) of 0.39 (0.84) elevations among PSE participants

    We reviewed research regarding system- and visit-level strategies to enhance clinical preventive service delivery and quality for adolescents and young adults. Despite professional consensus on recommended services for adolescents, a strong evidence base for services for young adults, and improved financial access to services with the Affordable Care Act's provisions, receipt of preventive services remains suboptimal. Further research that builds off successful models of linking traditional and community clinics is needed to improve access to care for all youth. To optimize the clinical encounter, promising clinician-focused strategies to improve delivery of preventive services include screening and decision support tools, particularly when integrated into electronic medical record systems and supported by training and feedback. Although results have been mixed, interventions have moved beyond increasing service delivery to demonstrating behavior change. Research on emerging technology-such as gaming platforms, mobile phone applications, and wearable devices-suggests opportunities to expand clinicians' reach; however, existing research is based on limited clinical settings and populations. Improved monitoring systems and further research are needed to examine preventive services facilitators and ensure that interventions are effective across the range of clinical settings where youth receive preventive care, across multiple populations, including young adults, and for more vulnerable populations with less access to quality care.

    Low back pain (LBP) is a prevalent condition and has been found to be recurrent and persistent in a majority of cases. Chiropractors have a preventive strategy, maintenance care (MC), aimed towards minimizing recurrence and progression of such conditions. The indications for recommending MC have been identified in the Nordic countries from hypothetical cases. This study aims to investigate whether these indications are indeed used in the clinical encounter. Data were collected in a multi-center observational study in which patients consulted a chiropractor for their non-specific LBP. Patient baseline information was a) previous duration of the LBP, b) the presence of previous episodes of LBP and c) early improvement with treatment. The chiropractors were asked if they deemed each individual patient an MC candidate. Logistic regression analyses (uni- and multi-level) were used to investigate the association of the patient variables with the chiropractor's decision. The results showed that "previous episodes" with LBP was the strongest predictor for recommending MC, and that the presence of all predictors strengthens the frequency of this recommendation. However, there was considerable heterogeneity among the participating chiropractors concerning the recommendation of MC. The study largely confirms the clinical use of the previously identified indications for recommending MC for recurrent and persistent LBP. Previous episodes of LBP was the strongest indicator.

    Dengue has become a major global public health threat with almost half of the world's population living in at-risk areas. Vaccination would likely represent an effective strategy for the management of dengue disease in endemic regions, however to date there is only one licensed preventative vaccine for dengue infection. The development of a vaccine against dengue virus (DENV) has been hampered by an incomplete understanding of protective immune responses against DENV. The most clinically advanced dengue vaccine is the chimeric yellow fever-dengue vaccine (CYD) that employs the yellow fever virus 17D strain as the replication backbone (Chimerivax-DEN; CYD-TDV). This vaccine had an overall pooled protective efficacy of 65.6% but was substantially more effective against severe dengue and dengue hemorrhagic fever. Several other vaccine approaches have been developed including live attenuated chimeric dengue vaccines (DENVax and LAV Delta 30), DEN protein subunit V180 vaccine (DEN1-80E) and DENV DNA vaccines. These vaccines have been shown to be immunogenic in animals and also safe and immunogenic in humans. However, these vaccines are yet to progress to phase III trials to determine their protective efficacy against dengue. This review will summarize the details of vaccines that have progressed to clinical trials in humans.

    The stress-tensor of a scalar field theory is not unique because of the possibility of adding an 'improvement term'. In supersymmetric field theories the stress-tensor will appear in a super-current multiplet along with the sypersymmetry current. The general question of the supercurrent multiplet for arbitrary deteriorated stress tensors and their relationship to supercurrent multiplets for models with gauge antisymmetric tensors is answered for various models of N = 1, 2 and 4 supersymmetry.

    To explore and understand medical-surgical nurses' perceived self-confidence and leadership abilities as first responders in recognising and responding to clinical deterioration prior to the arrival of an emergency response team. Patients are admitted to hospitals with multiple, complex health issues who are more likely to experience clinical deterioration. The majority of clinical deterioration events occur on medical-surgical units, and medical-surgical nurses are frequently the first healthcare professionals to identify signs and symptoms of clinical deterioration and initiate life-saving interventions. A prospective, cross-sectional, descriptive quantitative design using a survey method was used. Nurses were recruited from an integrated healthcare system located in the south-east United States. Nurses completed a demographic, a self-confidence and a leadership ability questionnaire. One hundred and forty-eight nurses participated in the study. Nurses felt moderately self-confident in recognising, assessing and intervening during clinical deterioration events. In addition, nurses felt moderately comfortable performing leadership skills prior to the arrival of an emergency response team. A significant, positive relationship was found between perceived self-confidence and leadership abilities. Age and certification status were significant predictors of nurses' leadership ability. Although nurses felt moderately self-confident and comfortable with executing leadership abilities, improvement is needed to ensure nurses are competent in recognising patients' deterioration cues and making sound decisions in taking appropriate, timely actions to rescue patients. Further strategies need to be developed to increase nurses' self-confidence and execution of leadership abilities in handling deterioration events for positive patient outcomes. Educational provisions should focus on various clinical deterioration events to build nurses' self-confidence and leadership abilities

    Full Text Available ABSTRACT: The main interest in the energy cane is the bioenergy production from the bagasse. The juice obtained after the cane milling may constitute a feedstock for the first-generation ethanol units; however, little attention has been dedicated to this issue. In order to verify the feasibility of the energy cane juice as substrate for ethanol production, the objectives of this research were first to determine the microbiological characteristics and deterioration along the time of the juices from two clones of energy cane (Type I and second, their fermentability as feedstock for utilization in ethanol distilleries. There was a clear differentiation in the bacterial and yeast development of the sugarcane juices assayed, being much faster in the energy canes than in sugarcane. The storage of juice for 8 hours at 30oC did not cause impact in alcoholic fermentation for any sample analyzed, although a significant bacterial growth was detected in this period. A decrease of approximately seven percentage points in the fermentative efficiency was observed for energy cane juice in relation to sugarcane in a 24-hour fermentation cycle with the baking yeast. Despite the faster deterioration, the present research demonstrated that the energy cane juice has potential to be used as feedstock in ethanol-producing industries. As far as we know, it is the first research to deal with the characteristics of deterioration and fermentability of energy cane juices.

    To determine the efficacy of skin protection wheelchair seat cushions in preventing pressure ulcers in the elderly nursing home population. Clinical trial with participants assigned at random to a skin protection or segmented foam cushion. Two hundred thirty-two participants were recruited between June 2004 and May 2008 and followed for 6 months or until pressure ulcer incidence. Twelve nursing homes. Nursing home residents aged 65 and older who were using wheelchairs for 6 or more hours per day and had a Braden score of 18 or less and a combined Braden activity and mobility score of 5 or less. Participants were recruited from a referred sample. All participants were provided with a fitted wheelchair and randomized into skin protection (SPC, n=113) or segmented foam (SFC, n=119) cushion groups. The SPC group received an air, viscous fluid and foam, or gel and foam cushion. The SFC group received a 7.6-cm crosscut foam cushion. Pressure ulcer incidence over 6 months for wounds near the ischial tuberosities (IT ulcers) were measured. Secondary analysis was performed on combined IT ulcers and ulcers over the sacrum and coccyx (sacral ulcers). One hundred eighty participants reached a study end point, and 42 were lost to follow-up. Ten did not receive the intervention. There were eight (6.7%) IT ulcers in the SFC group and one (0.9%) in the SPC group (P=.04). There were 21 (17.6%) combined IT and sacral ulcers in the SFC group and 12 (10.6%) in the SPC group (P=.14). Skin protection cushions used with fitted wheelchairs lower pressure ulcer incidence for elderly nursing home residents and should be used to help prevent pressure ulcers. © 2010, Copyright the Authors.

    Despite remarkable progress that has been achieved in the recent years in the diagnosis, prevention, and therapy for ventilator-associated pneumonia (VAP), this disease continues to create complication during the course of treatment in a significant proportion of patients while receiving mechanical ventilation. This study was designed to evaluate the effect of multimodality chest physiotherapy in intubated and mechanically ventilated patients undergoing treatment in the intensive care units (ICUs) for prevention of VAP. A total of 101 adult intubated and mechanically ventilated patients were included in this study. Manual hyperinflation (MH) and suctioning were administered to patients in the control group (n = 51), and positioning and chest wall vibrations in addition to MH plus suctioning (multimodality chest physiotherapy) were administered to patients in the study group (n = 50) till they were extubated. Both the groups were subjected to treatment twice a day. Standard care in the form of routine nursing care, pharmacological therapy, inhalation therapy, as advised by the concerned physician/surgeon was strictly implemented throughout the intervention period. Data were analyzed using SPSS window version 9.0. The Clinical Pulmonary infection Score (CPIS) Score showed significant decrease at the end of extubation/successful outcome or discharge in both the groups (P = 0.00). In addition, significant decrease in mortality rate was noted in the study group (24%) as compared to the control group (49%) (P = 0.007). It was observed in this study that twice-daily multimodality chest physiotherapy was associated with a significant decrease in the CPIS Scores in the study group as compared to the control group suggesting a decrease in the occurrence of VAP. There was also a significant reduction in the mortality rates with the use of multimodality chest physiotherapy in mechanically ventilated patients.

    This study analyzed the clinical characteristics of spinal cord injury (SCI) in children 10 years of age and younger, forms of prevention, and ways to improve treatment. Ninety-three children were reviewed between 1996 and 2009. The variables studied were type, age, cause, neurological level, association between SCI and traumatic brain injury (TBI), arthrodesis surgery, time elapsed between trauma and diagnosis, and causes of death. The statistical evaluations were done using the chi-square and ANOVA scales, in the SPSS program version 11.0. The most common cause was automobile crash accidents. Getting run over by a car was second (29.1 %), followed by firearm injuries (11.8 %). The thoracic spine was the most commonly impacted area. Evaluation showed that 83.9 % had complete neurological injury. Associated TBI was present in 35.5 % of the cases. Only 21.5 % of the patients required arthrodesis of the spine. In 31.2 % of the cases, myelopathy was not diagnosed at the time of the accident. There was no statistical correlation between TBI and a delayed diagnosis of SCI (p=0.231). Five children (5.4 %) died. The study showed that the cause of the trauma is associated to the child's age and that prevention is important. Trauma from automobile crash accidents was the main cause, and, in older children, firearm injuries are an important risk. Spinal cord injury was not always diagnosed in children at the time of accident. Educating family members and training emergency teams to adequately treat children with multiple traumas are measures that can help reduce the incidence of SCIs and neurological damage.

    Purpose In our ageing workforce, the increasing numbers of employees with chronic diseases are encouraged to prolong their working lives. It is important to prevent health deterioration in this vulnerable group. This study aims to investigate whether work characteristics predict health deterioration over a 3-year period among employees with (1) chronic diseases, and, more specifically, (2) musculoskeletal and psychological disorders. Methods The study population consisted of 5600 employees aged 45-64 years with a chronic disease, who participated in the Dutch Study on Transitions in Employment, Ability and Motivation (STREAM). Information on work characteristics was derived from the baseline questionnaire. Health deterioration was defined as a decrease in general health (SF-12) between baseline and follow-up (1-3 years). Crude and adjusted logistic regression analyses were performed to investigate prediction of health deterioration by work characteristics. Subgroup analyses were performed for employees with musculoskeletal and psychological disorders. Results At follow-up, 19.2% of the employees reported health deterioration (N = 1075). Higher social support of colleagues or supervisor predicted health deterioration in the crude analyses in the total group, and the groups with either musculoskeletal or psychological disorders (ORs 1.11-1.42). This effect was not found anymore in the adjusted analyses. The other work characteristics did not predict health deterioration in any group. Conclusions This study did not support our hypothesis that work characteristics predict health deterioration among employees with chronic diseases. As our study population succeeded continuing employment to 45 years and beyond, it was probably a relatively healthy selection of employees.

    Thallium intoxication was reported in cases with accidental ingestion, suicide attempt, and criminal adulteration. Reported cases were mostly one-time ingestion, therefore, the clinical course of divisional ingestion has not been fully known. Here, we report a case with two-step thallium intoxication manifesting as tardily accelerated neurologic deterioration. A 16-year-old adolescent was cryptically poisoned with thallium sulfate twice at an interval of 52days. After the first ingestion, neurologic symptoms including visual loss, myalgia, and weakness in legs developed about 40days after the development of acute gastrointestinal symptoms and alopecia. After the second ingestion, neurologic symptoms deteriorated rapidly and severely without gastrointestinal or cutaneous symptoms. Brain magnetic resonance imaging exhibited bilateral optic nerve atrophy. Nerve conduction studies revealed severe peripheral neuropathies in legs. Thallium intoxication was confirmed by an increase in urine thallium egestion. Most of the neurologic manifestations ameliorated in two years, but the visual loss persisted. The source of thallium ingestion was unraveled afterward because a murder suspect in another homicidal assault confessed the forepast adulteration. This discriminating clinical course may be attributable to the cumulative neurotoxicity due to the longer washout-time of thallium in the nervous system than other organs. It is noteworthy that the divisional thallium intoxication may manifest as progressive optic and peripheral neuropathy without gastrointestinal or cutaneous symptoms. Copyright © 2016 Elsevier Ltd.

    To compare the efficacy of behavior activation (BA) + low vision rehabilitation (LVR) with supportive therapy (ST) + LVR to prevent depressive disorders in patients with age-related macular degeneration (AMD). Single-masked, attention-controlled, randomized, clinical trial with outcome assessment at 4 months. Patients with AMD and subsyndromal depressive symptoms attending retina practices (n = 188). Before randomization, all subjects had 2 outpatient LVR visits, and were then randomized to in-home BA+LVR or ST+LVR. Behavior activation is a structured behavioral treatment that aims to increase adaptive behaviors and achieve valued goals. Supportive therapy is a nondirective, psychological treatment that provides emotional support and controls for attention. The Diagnostic and Statistical Manual IV defined depressive disorder based on the Patient Health Questionnaire-9 (primary outcome), Activities Inventory, National Eye Institute Vision Function Questionnaire-25 plus Supplement (NEI-VFQ), and NEI-VFQ quality of life (secondary outcomes). At 4 months, 11 BA+LVR subjects (12.6%) and 18 ST+LVR subjects (23.4%) developed a depressive disorder (relative risk [RR], 0.54; 95% CI, 0.27-1.06; P = 0.067). In planned adjusted analyses the RR was 0.51 (95% CI, 0.27-0.98; P = 0.04). A mediational analysis suggested that BA+LVR prevented depression to the extent that it enabled subjects to remain socially engaged. In addition, BA+LVR was associated with greater improvements in functional vision than ST+LVR, although there was no significant between-group difference. There was no significant change or between-group difference in quality of life. An integrated mental health and low vision intervention halved the incidence of depressive disorders relative to standard outpatient LVR in patients with AMD. As the population ages, the number of persons with AMD and the adverse effects of comorbid depression will increase. Promoting interactions between ophthalmology, optometry

    Full Text Available Purpose: To provide resource-stratified (four tiers, evidence-based recommendations on the primary prevention of cervical cancer globally. Methods: The American Society of Clinical Oncology convened a multidisciplinary, multinational panel of oncology, obstetrics/gynecology, public health, cancer control, epidemiology/biostatistics, health economics, behavioral/implementation science, and patient advocacy experts. The Expert Panel reviewed existing guidelines and conducted a modified ADAPTE process and a formal consensus-based process with additional experts (consensus ratings group for one round of formal ratings. Results: Existing sets of guidelines from five guideline developers were identified and reviewed; adapted recommendations formed the evidence base. Five systematic reviews, along with cost-effectiveness analyses, provided evidence to inform the formal consensus process, which resulted in agreement of ≥ 75%. Recommendations: In all resource settings, two doses of human papillomavirus vaccine are recommended for girls age 9 to 14 years, with an interval of at least 6 months and possibly up to 12 to 15 months. Individuals with HIV positivity should receive three doses. Maximal and enhanced settings: if girls are age ≥ 15 years and received their first dose before age 15 years, they may complete the series; if no doses were received before age 15 years, three doses should be administered; in both scenarios, vaccination may be through age 26 years. Limited and basic settings: if sufficient resources remain after vaccinating girls age 9 to 14 years, girls who received one dose may receive additional doses between age 15 and 26 years. Maximal, enhanced, and limited settings: if ≥ 50% coverage in the priority female target population, sufficient resources, and cost effectiveness, boys may be vaccinated to prevent other noncervical human papillomavirus–related cancers and diseases. Basic settings: vaccinating boys is not recommended

    Cloacal exstrophy (CE) and persistent cloaca (PC) (alternatively termed urorectal septum malformation sequence [URSMS]), represent two major cloacal defects (CDs). Clinical characteristics and risk factors often are studied for both defects combined, rather than exploring if these defects have different etiologies. We enumerated clinical features for 47 CE and 54 PC (inclusive of URSMS) cases from the National Birth Defects Prevention Study. Thirty-three CE cases were classified as isolated and 14 as multiple (presence of unassociated major defects); respective totals for PC cases were 26 and 28. We compared selected child and maternal characteristics between 11,829 non-malformed controls and CE and PC cases using chi-square or Fisher's exact tests. Compared to controls, CE and PC cases were statistically more likely (p < 0.05) to be preterm; CE cases were more likely to be multiple births. We conducted logistic regression analysis to estimate odds ratios and 95% confidence intervals for any CD, CE, and PC with selected self-reported maternal prepregnancy and periconceptional (one month prior to 3 months following conception) exposures. In crude and adjusted analyses, we observed significant positive associations for any CD, CE, and PC with use of any fertility medication or assisted reproductive technology procedure. Significant positive associations observed only in crude analyses were any CD with maternal obesity or use of progesterone, any CD and CE with any x-ray, and any CD and PC with use of folate antagonist medications. Our findings provide some of the first insights into potential differing etiologies for CE and PC. © 2017 Wiley Periodicals, Inc.

    In light of the known associations between stress, negative affect, and relapse, mindfulness strategies hold promise as a means of reducing relapse susceptibility. In a pilot randomized clinical trial, we evaluated the effects of Mindfulness Based Relapse Prevention (MBRP), relative to a health education control condition (HE) among stimulant dependent adults receiving contingency management. All participants received a 12-week contingency management (CM) intervention. Following a 4-week CM-only lead in phase, participants were randomly assigned to concurrently receive MBRP (n=31) or HE (n=32). Stimulant dependent adults age 18 and over. A university based clinical research center. The primary outcomes were stimulant use, measured by urine drug screens weekly during the intervention and at 1-month post-treatment, negative affect, measured by the Beck Depression Inventory and Beck Anxiety Inventory, and psychiatric severity, measured by the Addiction Severity Index. Medium effect sizes favoring MBRP were observed for negative affect and overall psychiatric severity outcomes. Depression severity changed differentially over time as a function of group, with MBRP participants reporting greater reductions through follow-up (p=0.03; Effect Size=0.58). Likewise, the MBRP group evidenced greater declines in psychiatric severity, (p=0.01; Effect Size=0.61 at follow-up). Among those with depressive and anxiety disorders, MBRP was associated with lower odds of stimulant use relative to the control condition (Odds Ratio= 0.78, p=0.03 and OR=0.68, p=0.04). MBRP effectively reduces negative affect and psychiatric impairment, and is particularly effective in reducing stimulant use among stimulant dependent adults with mood and anxiety disorders.

    Full Text Available Introduction: Upper airway angioedema is a life-threatening emergency department (ED presentation with increasing incidence. Angiotensin-converting enzyme inhibitor induced angioedema (AAE is a non-mast cell mediated etiology of angioedema. Accurate diagnosis by clinical examination can optimize patient management and reduce morbidity from inappropriate treatment with epinephrine. The aim of this study is to describe the incidence of angioedema subtypes and the management of AAE. We evaluate the appropriateness of treatments and highlight preventable iatrogenic morbidity. Methods: We conducted a retrospective chart review of consecutive angioedema patients presenting to two tertiary care EDs between July 2007 and March 2012. Results: Of 1,702 medical records screened, 527 were included. The cause of angioedema was identified in 48.8% (n=257 of cases. The most common identifiable etiology was AAE (33.1%, n=85, with a 60.0% male predominance. The most common AAE management strategies included diphenhydramine (63.5%, n=54, corticosteroids (50.6%, n=43 and ranitidine (31.8%, n=27. Epinephrine was administered in 21.2% (n=18 of AAE patients, five of whom received repeated doses. Four AAE patients required admission (4.7% and one required endotracheal intubation. Epinephrine induced morbidity in two patients, causing myocardial ischemia or dysrhythmia shortly after administration. Conclusion: AAE is the most common identifiable etiology of angioedema and can be accurately diagnosed by physical examination. It is easily confused with anaphylaxis and mismanaged with antihistamines, corticosteroids and epinephrine. There is little physiologic rationale for epinephrine use in AAE and much risk. Improved clinical differentiation of mast cell and non-mast cell mediated angioedema can optimize patient management.

  10. New concepts and challenges in the clinical translation of cancer preventive therapies: the role of pharmacodynamic biomarkers.

    Implementation of therapeutic cancer prevention strategies has enormous potential for reducing cancer incidence and related mortality. Trials of drugs including tamoxifen and aspirin have led the way in demonstrating proof-of-principle that prevention of breast and colorectal cancer is feasible. Many other compounds ranging from drugs in widespread use for various indications, including metformin, bisphosphonates, and vitamin D, to dietary agents such as the phytochemicals resveratrol and curcumin, show preventive activity against several cancers in preclinical models. Notwithstanding the wealth of opportunities, major challenges have hindered the development process and only a handful of therapies are currently approved for cancer risk reduction. One of the major obstacles to successful clinical translation of promising preventive agents is a lack of pharmacodynamic biomarkers to provide an early read out of biological activity in humans and for optimising doses to take into large scale randomised clinical trials. A further confounding factor is a lack of consideration of clinical pharmacokinetics in the design of preclinical experiments, meaning results are frequently reported from studies that use irrelevant or unachievable concentrations. This article focuses on recent findings from investigations with dietary-derived agents to illustrate how a thorough understanding of the mechanisms of action, using models that mimic the clinical scenario, together with the development of compound-specific accompanying pharmacodynamic biomarkers could accelerate the developmental pipeline for preventive agents and maximise the chances of success in future clinical trials. Moreover, the concept of a bell-shaped dose-response curve for therapeutic cancer prevention is discussed, along with the need to rethink the traditional 'more is better' approach for dose selection.

    Introduction With an increasing demand to improve patient safety within the NHS, it is important to ensure that measures are undertaken to continually improve patient care. Wrong site surgery has been defined as a 'never event'. This article highlights the importance of preventing wrong tooth extraction within orthodontics through an audit spiral over five years investigating the accuracy and clarity of orthodontic extraction letters at the University Dental Hospital of Manchester.Aims To examine compliance with the standards for accuracy and clarity of extraction letters and the incidence of wrong tooth extractions, and to increase awareness of the errors that can occur with extraction letters and of the current guidelines.Method A retrospective audit was conducted examining extraction letters sent to clinicians outside the department.Results It can be seen there has been no occurrence of a wrong site tooth extraction. The initial audit highlighted issues in conformity, with it falling below expected standards. Cycle two generally demonstrated a further reduction in compliance. Cycle three appeared to result in an increase in levels of compliance. Cycles 4 and 5 have demonstrated gradual improvements. However, it is noteworthy that in all cycles the audit standards were still not achieved, with the exception of no incidences of the incorrect tooth being extracted.Conclusion This audit spiral demonstrates the importance of long term re-audit to aim to achieve excellence in clinical care. There has been a gradual increase in standards through each audit.

    Emdogain has been shown in clinical and experimental studies to promote regeneration of all periodontal tissues: cementum with anchoring fibres, a functional, periodontal ligament and alveolar bone in connection with treatment of marginal periodontitis. The intention of this study was to analyse whether this regenerative capacity upon the periodontal ligament also worked in a trauma situation where a significant number of PDL cells have been eliminated because of unphysiologic storage or actual damage during avulsion or replantation. Furthermore if ankylosis sites already established because of earlier replantation after avulsion could be surgical removed and application of Emdogain could revert the ankylosis stage to a normal PDL situation. The first treatment situation was tested in seven patients with a total of 16 avulsed teeth with varying time of extra oral storage. The teeth were extra-orally endodontically treated and the root and socket covered with Emdogain before replantation. All teeth demonstrated subsequent ankylosis, primarily diagnosed by a percussion test. The second treatment situation where an ankylosis was already established constituted of seven patients with a total of 11 teeth because of previous replantation after avulsion. These teeth were all extracted, the ankylosis sites removed and the root and socket treated with Emdogain. After 6 months all teeth showed recurrence of ankylosis. It is concluded that Emdogain was not able to prevent or cure ankylosis.

    Radon is a naturally occurring radioactive gas and a level 1 carcinogen. It acts synergistically with cigarette smoke to cause lung cancer. In Ireland, radon is estimated to be associated with 13 % of all lung cancers. Rapid access lung cancer clinics (RALC's) were established in the UK and Ireland to improve lung cancer management outcomes. There has been no attempt to date to provide advice on household radon exposure assessments in this setting. We performed a prospective feasibility study of radon assessment in our RALC to test the hypothesis that patients would avail of this service and that it would provide an opportunity for secondary prevention in at risk persons. We investigated household radon levels in consecutive patients who were newly referred with symptoms of lung cancer to the RALC in Galway University Hospital, Ireland over a 6-month period. Of 50 patients enrolled, 42 returned valid results. Overall 21 % of patients had radon levels recorded above the national reference level. Only 5 % of patients were aware of the association between radon gas and lung cancer. Smokers were significantly less likely to engage fully in radon testing. The development of RALC's offers a novel opportunity to integrate the concepts of radon exposure, cigarette smoking and the development of lung cancer, and to reinforce this message in the minds of at risk patients.

    Full Text Available Background: Clostridium Difficile is the most common cause of antibiotic- associated diarrhea (AAD and antibiotic associated colitis (AAC in the hospital setting. In this Study, the preventive effect of Lactobacillus coagulance probiotic preparation was investigated on AAD and AAC. Material and Methods: In this double blind randomized clinical trial study, 300 patients under antibiotics treatment according to our inclusion and exclusion criteria were enrolled to the study and randomly divided into two groups, case (tab probiotic, 100mg/day and control group (placebo from initial antibiotic administration till one week after termination of antibiotic consumption. All patients were trained about the signs of diarrhea and colitis. Colitis signs, incidence of diarrhea and its culture findings for the presence of the toxin of Clostridium difficile were recorded and compared between groups. Data were analyzed with appropriate statistical tests and using version 16 of SPSS statistical software. Results: Antibiotic associated diarrhea (AAD was seen in 10 (6.6% and 16 (%10.6 patients of case and control group respectively. There was no significant difference between groups in AAD incidence and positive stool exam regarding the presence of Clostridium difficile toxin. Colitis syndrome were develop in 34 (22.8% and 86 (57% patients of the probiotic and placebo group respectively that was significantly low in case group (p<0.001. Conclusion: There was no statistically significant difference between probiotic group and placebo group in reducing AAD. But, consumption of Lactobacillus coagulance probiotic can reduce the incidence of antibiotic associated colitis.

    2014-01-01

    Full Text Available Objective. This clinical trial was designed to investigate whether goshajinkigan reduces the onset of diabetic complications or not. Materials and Methods. A total of 332 type 2 diabetic mellitus patients were registered from 9 clinical centers from March 2000 to August 2007. Patients were randomly assigned to take goshajinkigan extract powder, 2.5 grams for 3 times a day or no kampo therapy, additionally to the regular treatment. The primary endpoints were the onset of macrovascular diseases or progression of nephropathy or retinopathy. Statistical analysis was performed by the intention-to-treat method. Results. After 5 years of observation, 116 patients were submitted to analysis. Among them, no macrovascular events were observed in both groups. Although 43 participants had upstaging of retinopathy or nephropathy in total, there was no significant difference between goshajinkigan group and control group. Deterioration of ankle reflex was suppressed in goshajinkigan group. Also glycated hemoglobin, and fasting plasma glucose were decreased in the goshajinkigan group. Conclusion. Although the power of analysis was too low to demonstrate any effects of goshajinkigan on the progression of macrovascular diseases, retinopathy or nephropathy, goshajinkigan may be beneficial for diabetic neuropathy and glycemic control.

    Hospitals can experience difficulty in detecting and responding to early signs of patient deterioration leading to late intensive care referrals, excess mortality and morbidity, and increased hospital costs. Our study aims to explore potential indicators of physiological deterioration by the analysis of vital-signs. The dataset used comprises heart rate (HR) measurements from MIMIC II waveform database, taken from six patients admitted to the Intensive Care Unit (ICU) and diagnosed with severe sepsis. Different indicators were considered: 1) generic early warning indicators used in ecosystems analysis (autocorrelation at-1-lag (ACF1), standard deviation (SD), skewness, kurtosis and heteroskedasticity) and 2) entropy analysis (kernel entropy and multi scale entropy). Our preliminary findings suggest that when a critical transition is approaching, the equilibrium state changes what is visible in the ACF1 and SD values, but also by the analysis of the entropy. Entropy allows to characterize the complexity of the time series during the hospital stay and can be used as an indicator of regime shifts in a patient's condition. One of the main problems is its dependency of the scale used. Our results demonstrate that different entropy scales should be used depending of the level of entropy verified.

    The purpose of the current study was to evaluate feasibility and efficacy of two promising approaches to indicated prevention of disordered gambling in a college population. Randomized clinical trial with assignment to a personalized feedback intervention (PFI), cognitive-behavioral intervention (CBI) or assessment-only control (AOC). PFI was delivered individually in a single session and included feedback regarding gambling behavior, norms, consequences and risk-reduction tips, delivered in a motivational interviewing style. CBI was delivered in small groups over four to six sessions and included functional analysis and brief cognitive correction, as well as identification of and alternatives for responding to gambling triggers. College campus. At-risk or probable pathological gamblers (n = 147; 65.3% male; group assignment: PFI, n = 52; CBI, n = 44; AOC, n = 51). Self-reported gambling quantity, frequency, consequences, psychopathology, normative perceptions and beliefs. Relative to control, results at 6-month follow-up indicated reductions in both interventions for gambling consequences (PFI d = 0.48; CBI d = 0.39) and DSM-IV criteria (PFI d = 0.60; CBI d = 0.48), reductions in frequency for PFI (d = 0.48). CBI was associated with reduced illusions of control, whereas PFI was associated with reduced perceptions of gambling frequency norms. Reductions in perceived gambling frequency norms mediated effects of PFI on gambling frequency. A single-session personalized feedback intervention and a multi-session cognitive-behavioral intervention may be helpful in reducing disordered gambling in US college students. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

    Although controversy exists regarding the efficacy of antibiotic prophylaxis for patients at risk of infective endocarditis, expert committees continue to publish recommendations for antibiotic prophylaxis regimens. This study aimed to evaluate the efficacy of four antimicrobial regimens for the prevention of bacteraemia following dental extractions. The study population included 266 adults requiring dental extractions who were randomly assigned to the following five groups: control (no prophylaxis); 1000/200 mg of amoxicillin/clavulanate intravenously; 2 g of amoxicillin by mouth; 600 mg of clindamycin by mouth; and 600 mg of azithromycin by mouth. Venous blood samples were collected from each patient at baseline and at 30 s, 15 min and 1 h after dental extractions. Samples were inoculated into BACTEC Plus culture bottles and processed in the BACTEC 9240. Conventional microbiological techniques were used for subcultures and further identification of the isolated bacteria. The trial was registered at ClinicalTrials.gov with ID number NCT02115776. The incidence of bacteraemia in the control, amoxicillin/clavulanate, amoxicillin, clindamycin and azithromycin groups was: 96%, 0%, 50%, 87% and 81%, respectively, at 30 s; 65%, 0%, 10%, 65% and 49% at 15 min; and 18%, 0%, 4%, 19% and 18% at 1 h. Streptococci were the most frequently identified bacteria. The percentage of positive blood cultures at 30 s post-extraction was lower in the amoxicillin/clavulanate group than in the amoxicillin group (P dental extractions was undetectable with amoxicillin/clavulanate prophylaxis. Alternative antimicrobial regimens should be sought for patients allergic to the β-lactams. © The Author 2016.

  7. Prevention of thrombosis in pregnancy: how practical are consensus derived clinical practice guidelines?

    2012-11-01

    Thromboembolic disease (TED) has, for many years, consistently been identified as one of the leading causes of direct maternal mortality. In November 2009, the RCOG published a guideline on the prevention of TED that has been rapidly adopted by hospital trusts in the UK. The aim of our study was to determine the number and profile of women in our population that would require treatment with low molecular weight heparin (LMWH) and the cost implications of such treatment if these guidelines were implemented. A retrospective review of the first 100 women who delivered at the Coombe Women & Infants University Hospital (CWIUH) in 2010 was conducted and risk stratification applied at the relevant time points. A total of 51% were deemed to be at intermediate or high risk of TED at some point during pregnancy. In 35 of the 51 women (70%), this risk was attributable to factors such as age>35 years, parity≥3, BMI>30 kg\\/m2 or cigarette smoking. In our obstetric population, the percentage of women with these risk factors was: 25.5%, 8.5%, 19% and 16.7%, respectively. Implementation of this guideline would increase the hospital annual expenditure on LMWH by a factor of 17. The strategy of attributing risk by accumulating factors that individually have a low risk of TED and are prevalent in the population needs to be re-visited. The cost of implementation of these guidelines is not inconsiderable in the absence of data to indicate that clinical outcome is improved with their implementation.

    Analyze clustering of unhealthy lifestyle behavior and its relationship with nonadherence to clinical preventive care services among Spanish diabetic adults. Cross-sectional study including 2156 diabetic adults from the 2006 Spanish National Health Survey. Subjects were asked about their uptake of BP measurement, lipid profile, influenza vaccination, and dental examination. Lifestyle behaviors included smoking status, physical activity, alcohol consumption, and dieting. Binary logistic regression models were built to assess the association between clustering of unhealthy lifestyle and the uptake of each preventive activity. Almost 16% and 36% of the subjects had not undergone blood pressure (BP) and blood lipids measurements, respectively. Forty percent had not been vaccinated and 72% had not received dental examination. Fourteen percent of the subjects had three to four unhealthy behaviors and this increased the probability of not having BP check-up (OR 2.32, 95% CI 1.38-3.91), blood lipids testing (OR 1.63, 95% CI 1.14-2.33), and not being vaccinated (OR 1.99, 95% CI 1.37-2.89). Number of unhealthy lifestyle behaviors is linearly associated with number of preventive measures unfulfilled. Adherence to recommended clinical preventive services is under desirable levels among Spanish diabetes sufferers. These preventive services are provided neither equitably nor efficiently, since subjects with unhealthier lifestyles are less likely to receive them. Copyright © 2011 Elsevier Inc.

Background  Travellers’ compliance with measures to prevent influenza through the use of antivirals and influenza vaccine remains very poor despite influenza being one of the commonest travel and vaccine‐preventable diseases. A study was undertaken to assess travellers’ beliefs, perceptions and intentions to take antivirals for the treatment and prevention of influenza during the H1N1 pandemic. Methods  A cross‐sectional survey (n = 96) of travellers who attended the Royal Free Travel Health Centre, London, UK was undertaken in September 2009. A self‐administered questionnaire was completed by a traveller in advance of their pre‐travel health consultation. Logistic regression identified variables independently associated with compliance. Results  Influenza vaccination uptake for the 5 years preceding the study was found to be 20·8%. This was statistically significantly higher for older travellers and those with underlying health conditions (P intention to comply with antiviral drugs on a preventive and therapeutic basis was 58% and 72%, respectively, and this varied markedly with age and with dispensed antimalarial chemoprophylaxis. Conclusion  This study identifies some beliefs and perceptions travellers consider with regard to the therapeutic and preventive influenza use of antivirals during the H1N1 pandemic; it underscores the importance of travellers receiving hemisphere appropriate influenza vaccination. The external validity of these study findings requires further corroboration involving other travel clinics and different cohorts of travellers during seasonal activity or outbreaks of influenza. These findings could guide the development of future strategies for the prevention of influenza

    Medication errors may lead to adverse drug events (ADEs), which endangers patient safety and increases healthcare-related costs. The on-ward deployment of clinical pharmacists has been shown to reduce preventable ADEs, and save costs. The purpose of this study was to evaluate the ADEs prevention and cost-saving effects by clinical pharmacist deployment in a nephrology ward.This was a retrospective study, which compared the number of pharmacist interventions 1 year before and after a clinical pharmacist was deployed in a nephrology ward. The clinical pharmacist attended ward rounds, reviewed and revised all medication orders, and gave active recommendations of medication use. For intervention analysis, the numbers and types of the pharmacist's interventions in medication orders and the active recommendations were compared. For cost analysis, both estimated cost saving and avoidance were calculated and compared.The total numbers of pharmacist interventions in medication orders were 824 in 2012 (preintervention), and 1977 in 2013 (postintervention). The numbers of active recommendation were 40 in 2012, and 253 in 2013. The estimated cost savings in 2012 and 2013 were NT$52,072 and NT$144,138, respectively. The estimated cost avoidances of preventable ADEs in 2012 and 2013 were NT$3,383,700 and NT$7,342,200, respectively. The benefit/cost ratio increased from 4.29 to 9.36, and average admission days decreased by 2 days after the on-ward deployment of a clinical pharmacist.The number of pharmacist's interventions increased dramatically after her on-ward deployment. This service could reduce medication errors, preventable ADEs, and costs of both medications and potential ADEs.

    In this paper, we are using optimal control approach to determine the optimal rate in production. Most of the inventory production models deal with a single item. First build the mathematical models inventory stochastic, in this model we also assume that the items are in the same store. The mathematical model of the problem inventory can be deterministic and stochastic models. In this research will be discussed how to model the stochastic as well as how to solve the inventory model using optimal control techniques. The main tool in the study problems for the necessary optimality conditions in the form of the Pontryagin maximum principle involves the Hamilton function. So we can have the optimal production rate in a production inventory system where items are subject deterioration.

    A simple system or mechanism for engine Oil (lubricating oil) deterioration monitoring is a need. As engine oil is an important element in I C engines and it is exposed to various strains depending on the operating conditions. If it becomes contaminated with dirt and metal particles, it can become too thick or thin and loses its protective properties, leads to unwanted friction. In turn, to avoid an engine failure, the oil must be changed before it loses its protective properties, which may be harmful to engine which deteriorates vehicle performance. At the same time, changing the lubricant too early, cause inefficient use of already depleting resources, also unwanted impact on the environment and economic reasons. Hence, it will be always helpful to know the quality of the oil under use. With this objective, the research work had been undertaken to develop a simple capacitance sensor for quantification of the quality of oil under use. One of the investigated parameter to quantify oil degradation is Viscosity (as per standard testing procedure: DIN 51562-1). In this research work, an alternative method proposed which analyzing change in capacitance of oil, to quantify the quality of oil underuse and compared to a conventional standard method. The experimental results reported in this paper shows trend for the same. Engine oil of grade SAE 15W40 used for light-duty vehicle, vans and passenger cars is used for experimentation. Suggested method can form a base for further research to develop a cost-effective method for indicating the time to change in engine oil quality have been presented.

    The response of forest ecosystems to increased atmospheric CO2 is constrained by nutrient availability. It is thus crucial to account for nutrient limitation when studying the forest response to climate change. The objectives of this study were to describe the nutritional status of the main European tree species, to identify growth-limiting nutrients and to assess changes in tree nutrition during the past two decades. We analysed the foliar nutrition data collected during 1992-2009 on the intensive forest monitoring plots of the ICP Forests programme. Of the 22 significant temporal trends that were observed in foliar nutrient concentrations, 20 were decreasing and two were increasing. Some of these trends were alarming, among which the foliar P concentration in F. sylvatica, Q. Petraea and P. sylvestris that significantly deteriorated during 1992-2009. In Q. Petraea and P. sylvestris, the decrease in foliar P concentration was more pronounced on plots with low foliar P status, meaning that trees with latent P deficiency could become deficient in the near future. Increased tree productivity, possibly resulting from high N deposition and from the global increase in atmospheric CO2, has led to higher nutrient demand by trees. As the soil nutrient supply was not always sufficient to meet the demands of faster growing trees, this could partly explain the deterioration of tree mineral nutrition. The results suggest that when evaluating forest carbon storage capacity and when planning to reduce CO2 emissions by increasing use of wood biomass for bioenergy, it is crucial that nutrient limitations for forest growth are considered. © 2014 John Wiley & Sons Ltd.

    Full Text Available Purpose: The purpose of this paper to develop an inventory model for instantaneous deteriorating items with the consideration of the facts that the deterioration rate can be controlled by using the preservation technology (PT and the holding cost & demand rate both are linear function of time which was treated as constant in most of the deteriorating inventory model. Design/methodology/approach: Developed the mathematical equation of deterministic deteriorating inventory model in which demand rate and holding cost both is linear function of time, deterioration rate is constant, backlogging rate is variable and depend on the length of the next replenishment, shortages are allowed and partially backlogged and obtain an analytical solution which optimizes the total cost of the proposed inventory model. Findings: The model can be applied for optimizing the total inventory cost of deteriorating items inventory for such business enterprises where they use the preservation technology to control the deterioration rate under other assumptions of the model. Originality/value: The inventory system for deteriorating items has been an object of study for a long time, but little is known about the effect of investing in reducing the rate of product deterioration and their significant impact in the business. The proposed model is effective as well as efficient for the business organization that uses the preservation technology to reduce the deterioration rate of the instantaneous deteriorating items of the inventory.

    There are no nationwide, population-based studies in Spain assessing overall cardiovascular risk. We aimed to describe cardiovascular risk and achievement of treatment goals following the 2012 European Guidelines on cardiovascular disease prevention strategy. We also investigated clinical characteristics (non-classical risk factors) associated with moderate risk. Participants (n=2310, 58% women) aged 40 to 65 years from a national population-based study (Di@bet.es Study) were identified. First, a priori high/very-high risk individuals were identified. Next, total cardiovascular risk (Systematic Coronary Risk Evaluation equation including high-density lipoprotein cholesterol) was used to assess risk of a priori non-high risk individuals. Variables independently associated with moderate versus low-risk were investigated by multiple logistic regression analysis. Age-and-sex standardized (direct method) percentages of high/very-high, moderate, and low-risk were 22.8%, 43.5%, and 33.7%, respectively. Most men were at moderate (56.2%), while 55.4% of women were at low risk. Low-density lipoprotein cholesterol (< 70,<100, < 115 mg/dL) and blood pressure (<140/90 mmHg) goals for very-high, high and moderate risk were met in 15%, 26% and 46%, and 77%, 68% and 85% of the individuals, respectively. Body mass index, high triglycerides concentrations, diastolic blood pressure, and low Mediterranean diet adherence (in women) were independently associated with moderate (versus low) risk. Cardiovascular risk in Spain is mainly moderate in men and low in women. Achievement of treatment goals in high-risk individuals should be improved. The prevalence of non-classical cardiovascular risk factors is elevated in subjects at moderate risk, an important aspect to consider in a population-based strategy to decrease cardiovascular disease in the most prevalent group.

    2012-01-01

    Full Text Available The main ultimate goal of secondary prevention of osteoporosis (OP is to reduce the risk of fracture in patients with the already existing disease; the effect of pathogenetic agents develops only if they are used regularly and long. Low patient adherence to treatment minimizes all efforts to prevent OP complications. There is low-frequency prescription of pathogenetic antiosteoporotic agents to this category of patients. There is a wide range of pathogenetic antiosteoporotic drugs today. On choosing a medicine, a physician should rely on its proven efficacy and safety, as well as its convenience use for a specific patient. The data of an international clinical trial to prevent fractures during long-term therapy with strontium ranelate are given.

    Mexican American males have higher levels of total cholesterol and triglycerides, higher body mass indexes, and a higher prevalence of diabetes than do non-Hispanic White males. They are the least likely Hispanic subgroup to be insured, to have recently visited a physician, or to have preventive exams. To explore factors related to the use of preventive exams among mature men, and specifically among Mexican American men residing along the Arizona, United States/Sonora, Mexico border, information on barriers and motivating factors to male participation in preventive screening exams was collected. Interviews were conducted with mature men and women from a single border community and with clinical staff from three different border communities who deliver services to similar populations. Responses were triangulated. Common themes identified include health education/information/advertisement and female/family support as motivating factors and machismo/denial/fatalism as a barrier to male health-seeking behavior.

    Ventilator-associated conditions (VACs) and infection-related ventilator-associated complications (iVACs) are the Centers for Disease Control and Prevention's new surveillance paradigms for patients who are mechanically ventilated. Little is known regarding the clinical impact and preventability of VACs and iVACs and their relationship to ventilator-associated pneumonia (VAP). We evaluated these using data from a large, multicenter, quality-improvement initiative. We retrospectively applied definitions for VAC and iVAC to data from a prospective time series study in which VAP clinical practice guidelines were implemented in 11 North American ICUs. Each ICU enrolled 30 consecutive patients mechanically ventilated > 48 h during each of four study periods. Data on clinical outcomes and concordance with prevention recommendations were collected. VAC, iVAC, and VAP rates over time, the agreement (κ statistic) between definitions, associated morbidity/mortality, and independent risk factors for each were determined. Of 1,320 patients, 139 (10.5%) developed a VAC, 65 (4.9%) developed an iVAC, and 148 (11.2%) developed VAP. The agreement between VAP and VAC was 0.18, and between VAP and iVAC it was 0.19. Patients who developed a VAC or iVAC had significantly more ventilator days, hospital days, and antibiotic days and higher hospital mortality than patients who had neither of these conditions. Increased concordance with VAP prevention guidelines during the study was associated with decreased VAP and VAC rates but no change in iVAC rates. VACs and iVACs are associated with significant morbidity and mortality. Although the agreement between VAC, iVAC, and VAP is poor, a higher adoption of measures to prevent VAP was associated with lower VAP and VAC rates.

    2013-01-01

    Researchers have found that patients exhibit physiological changes up to 8 hours prior to an arrest event. Deaths have been attributed to a lack of observation, lack of documentation of observations, inability of a caregiver to recognize early signs of deterioration, and lack of communication between healthcare providers. This integrative review examines early warning scoring systems and their effectiveness in predicting a patient's potential for deterioration and considers whether these scoring systems prevent unplanned intensive care unit admissions and/or death. Three databases (MEDLINE, CINAHL [Cumulative Index to Nursing and Allied Health Literature], and the Cochrane Collaboration) were searched to identify the instruments and clinical support systems available to assist healthcare personnel in recognizing early clinical deterioration. Key search words included modified early warning score, early warning score, early warning systems, deteriorating patient, patients at risk, shock index, track and trigger systems, and failure to rescue. Two prior literature reviews examined early warning scoring systems and their effects on patient outcomes; however, the most recent one reviewed only articles published before 2007. This review examined studies of early warning systems and the incorporation of clinical support published from 2007 to 2012. Nine studies fitting the search criteria were included in this review. Early warning scoring systems that interface with electronic medical records and are supplemented with decision aides (algorithms) and clinical support systems produce an effective screening system for early identification of deteriorating patients. This multifaceted approach decreases unplanned intensive care unit admissions and hospital mortality.

    To characterize information on diabetes prevention appearing in Japanese general health magazines and to examine the agreement of the content with that in clinical practice guidelines for the treatment of diabetes in Japan. We used the Japanese magazines' databases provided by the Media Research Center and selected magazines with large print runs published in 2006. Two medical professionals independently conducted content analysis based on items in the diabetes prevention guidelines. The number of pages for each item and agreement with the information in the guidelines were determined. We found 63 issues of magazines amounting to 8,982 pages; 484 pages included diabetes prevention related content. For 23 items included in the diabetes prevention guidelines, overall agreement of information printed in the magazines with that in the guidelines was 64.5% (471 out of 730). The number of times these items were referred to in the magazines varied widely, from 247 times for food items to 0 times for items on screening for pregnancy-induced diabetes, dyslipidemia, and hypertension. Among the 20 items that were referred to at least once, 18 items showed more than 90% agreement with the guidelines. However, there was poor agreement for information on vegetable oil (2/14, 14%) and for specific foods (5/247, 2%). For the fatty acids category, "fat" was not mentioned in the guidelines; however, the term frequently appeared in magazines. "Uncertainty" was never mentioned in magazines for specific food items. The diabetes prevention related content in the health magazines differed from that defined in clinical practice guidelines. Most information in the magazines agreed with the guidelines, however some items were referred to inappropriately. To disseminate correct information to the public on diabetes prevention, health professionals and the media must collaborate.

    The aim of this study was to explore nurses' experiences assessing and managing deteriorating patients in practice following completion of a relevant post-registration education programme. Recognising the increasing acuity of ward patients, nurses are faced with patients who are at an increased risk of deterioration. Patients who are acutely ill or deteriorating often exhibit periods of physiological deterioration; however there is evidence illustrating that these clinical changes are frequently missed, misinterpreted or mismanaged in practice. In order to prepare nurses to competently assess and manage the deteriorating patient, education as a care initiative is offered to develop the knowledge and skills required. A qualitative study using critical incident analysis was conducted to acquire narrative data from nurses, describing their clinical practice experiences of patient deterioration. Thematic analysis was used to analyse the data. Findings revealed improvements in nurses' abilities to recognise patient deterioration, greater application of the evidence base and an increase in confidence and assertiveness. There was some evidence of applying the knowledge and skills learned, however equally some nurses indicated that they remained ill-prepared to apply the skills in practice. Crown Copyright © 2017.

    User-friendly scores to assess knowledge of guidelines for prevention of ventilator-associated pneumonia (VAP) are scarce and have mainly evaluated nurses, but not students or physicians. Gaps between knowledge and actual clinical practice have not been sufficiently analyzed. We assessed knowledge of and adherence to guidelines for prevention of VAP among physicians, nurses, and students in adult ICUs. All adult ICU healthcare workers were invited to complete a 20-point questionnaire. The first part assessed personal knowledge of international guidelines for prevention of VAP; the second part assessed daily clinical practice. Personal knowledge and daily practice were scored from 0 to 10 points. We invited 257 ICU healthcare workers to participate in the study, and 167 (65%) accepted (32/54 physicians, 108/176 nurses, and 27/27 students). The median (IQR) personal knowledge scores for physicians, nurses, and students were 6 (5-7), 5 (4-6), and 5 (4-7), respectively. The median scores for daily clinical practice for physicians and nurses were 5 (4-6) and 4 (3-5), respectively. Healthcare workers with more than 1 year of ICU experience scored significantly better in personal knowledge than those with less experience: 6 (5-7) versus 4 (3-6), P = .004. A simple, easy-to-complete questionnaire enabled us to rapidly evaluate personal knowledge and reported clinical practice in prevention of VAP in large teaching institutions. These scores will be used as baseline figures to assess the impact of educational and intervention campaigns.

    2017-01-01

    The number of bariatric procedures has exponentially increased in the past decade, as a result of the lack of successful clinical weight-loss interventions. The main reasons for the failure of clinical obesity management are: (1) anti-obesity medications are administered as monotherapies (or pre-combined drugs); (2) lack of combination between pharmacotherapy and non-pharmacological modalities; (3) short duration of pharmacotherapy for obesity; (4) lack of weight-loss maintenance strategies; (5) misunderstanding of the complex pathophysiology of obesity; and (6) underprescription of anti-obesity medications. We developed a protocol that can potentially overcome the drawbacks that may lead to the failure of clinical therapy for obesity. The aim of this study is therefore to report the clinical and metabolic effects of our proposed obesity-management protocol over a 2-year period, and to determine whether this more intensive approach to obesity management is feasible and a possible alternative to bariatric surgery in patients with moderate-to-severe obesity. This retrospective study involved 43 patients in whom bariatric surgery was indicated. Patients underwent an intensive anti-obesity protocol that included pharmacotherapy with multiple drugs; intense surveillance with monthly body analysis by air-displacement plethysmography, electrical bioimpedance, and 3D body scans; weekly psychotherapy; diet planning with a dietician every 2 months; and exercises at least 3 times a week with exercises prescribed by a personal trainer at least once a month. Body weight (BW), total weight excess (TWE), obesity class, body mass index, fat weight, muscle weight, waist circumference, and visceral fat were analyzed. Markers of lipid and glucose metabolism, liver function, and inflammation were also evaluated. Therapeutic success was defined as >20% BW loss or >50% decrease in TWE after 1 year. Significant improvements were observed in all clinical and metabolic parameters. Thirty

    In today's dental school curricula, an increasing amount of time is dedicated to technological advances, and preventive dentistry topics may not be adequately addressed. Freshman (D1) students participated in a new Introduction to Preventive Dentistry course, which consisted of didactic lectures, active learning breakout sessions and case-based studies. The goal of this study was to determine if D1 dental students completing the course had a better knowledge and comfort level with basic preventive dentistry concepts and caries risk assessment than the upcoming graduating senior dental students. Following the completion of the course, D1 students were administered a survey that assessed their comfort level describing preventive dentistry topics to patients. This was immediately followed by an unannounced examination over the same topics. Senior (D4) students, who had not taken a formal course, reported statistically significant higher comfort levels than D1 students. However, the D4s scored significantly lower in all of the examination areas than the D1 students. Higher scores in D1s may have been due to recent exposure to the course material. However, the basic nature of the content-specific questions should be easily answered by novice practitioners educating their patients on oral disease prevention. As the current data shows lower content-specific scores of basic preventive dentistry knowledge amongst graduating D4 students, this may indicate a need for more guidance and education of students during the patient care. This study showed that implementation of a formalised course for D1 students can successfully ameliorate deficiencies in knowledge of preventive dentistry topics. © 2014 John Wiley & Sons A/S.

    Observed seroincidence and prevalence rates in male-to-female (MTF) transgender individuals highlight the need for effective targeted HIV prevention strategies for this community. In order to develop an effective vaccine that can be used by transgender women, researchers must understand and address existing structural issues that present barriers to this group's participation in HIV vaccine clinical trials. Overcoming barriers to participation is important for ensuring HIV vaccine acceptability and efficacy for the MTF transgender community. To explore barriers and facilitators to MTF transgender participation in preventive HIV vaccine clinical trials, the HIV Vaccine Trials Network conducted focus groups among transgender women in four urban areas (Atlanta, Boston, Philadelphia, and San Francisco). Barriers and facilitators to engagement of transgender women in preventive HIV vaccine clinical trials led to the following recommendations: (a) transgender cultural competency training, (b) creating trans-friendly environments, (c) true partnerships with local trans-friendly organizations and health care providers, (d) protocols that focus on transgender specific issues, and (e) data collection and tracking of transgender individuals. These results have implications for the conduct of HIV vaccine trials, as well as engagement of transgender women in research programs in general.

    Few results from programmes based on combination prevention methods are available. We propose to analyse the degree of protection provided by postexposure prophylaxis (PEP) for consensual sexual activity at healthcare clinics, its compensatory effects on sexual behaviour; and the effectiveness of combination prevention methods and pre-exposure prophylaxis (PrEP), compared with exclusively using traditional methods. A total of 3200 individuals aged 16 years or older presenting for PEP at 5 sexually transmitted disease (STD)/HIV clinics in 3 regions of Brazil will be allocated to one of two groups: the PEP group-individuals who come to the clinic within 72 h after a sexual exposure and start PEP; and the non-PEP group-individuals who come after 72 h but within 30 days of exposure and do not start PEP. Clinical follow-up will be conducted initially for 6 months and comprise educational interventions based on information and counselling for using prevention methods, including PrEP. In the second study phase, individuals who remain HIV negative will be regrouped according to the reported use of prevention methods and observed for 18 months: only traditional methods; combined methods; and PrEP. Effectiveness will be analysed according to the incidence of HIV, syphilis and hepatitis B and C and protected sexual behaviour. A structured questionnaire will be administered to participants at baseline and every 6 months thereafter. Qualitative methods will be employed to provide a comprehensive understanding of PEP-seeking behaviour, preventive choices and exposure to HIV. This study will be conducted in accordance with the resolution of the School of Medicine Research Ethics Commission of Universidade de São Paulo (protocol no. 251/14). The databases will be available for specific studies, after management committee approval. Findings will be presented to researchers, health managers and civil society members by means of newspapers, electronic media and scientific journals

    Postpericardiotomy syndrome, postoperative atrial fibrillation (AF), and postoperative effusions may be responsible for increased morbidity and health care costs after cardiac surgery. Postoperative use of colchicine prevented these complications in a single trial. To determine the efficacy and safety of perioperative use of oral colchicine in reducing postpericardiotomy syndrome, postoperative AF, and postoperative pericardial or pleural effusions. Investigator-initiated, double-blind, placebo-controlled, randomized clinical trial among 360 consecutive candidates for cardiac surgery enrolled in 11 Italian centers between March 2012 and March 2014. At enrollment, mean age of the trial participants was 67.5 years (SD, 10.6 years), 69% were men, and 36% had planned valvular surgery. Main exclusion criteria were absence of sinus rhythm at enrollment, cardiac transplantation, and contraindications to colchicine. Patients were randomized to receive placebo (n=180) or colchicine (0.5 mg twice daily in patients ≥70 kg or 0.5 mg once daily in patients <70 kg; n=180) starting between 48 and 72 hours before surgery and continued for 1 month after surgery. Occurrence of postpericardiotomy syndrome within 3 months; main secondary study end points were postoperative AF and pericardial or pleural effusion. The primary end point of postpericardiotomy syndrome occurred in 35 patients (19.4%) assigned to colchicine and in 53 (29.4%) assigned to placebo (absolute difference, 10.0%; 95% CI, 1.1%-18.7%; number needed to treat = 10). There were no significant differences between the colchicine and placebo groups for the secondary end points of postoperative AF (colchicine, 61 patients [33.9%]; placebo, 75 patients [41.7%]; absolute difference, 7.8%; 95% CI, -2.2% to 17.6%) or postoperative pericardial/pleural effusion (colchicine, 103 patients [57.2%]; placebo, 106 patients [58.9%]; absolute difference, 1.7%; 95% CI, -8.5% to 11.7%), although there was a reduction in

    The VI European Guidelines for Cardiovascular Prevention recommend combining population and high-risk strategies with lifestyle changes as a cornerstone of prevention, and propose the SCORE function to quantify cardiovascular risk. The guidelines highlight disease specific interventions, and conditions as women, young people and ethnic minorities. Screening for subclinical atherosclerosis with noninvasive imaging techniques is not recommended. The guidelines distinguish four risk levels (very high, high, moderate and low) with therapeutic objectives for lipid control according to risk. Diabetes mellitus confers a high risk, except for subjects with type 2 diabetes with less than alcohol abuse. Copyright © 2017. Publicado por Elsevier España, S.L.U.

    Plasticized poly (vinyl chloride) (PVC) in museum collections deteriorates by migration, loss and chemical breakdown of the plasticizer, accompanied by dehydrochlorination of the polymer. The extent, rate and mechanisms of deterioration of new and deteriorated plasticized PVC were compared during...... of samples. Optical densitometry was used to quantify darkening of the PVC component of samples. Degradation of new and deteriorated PVC was inhibited by enclosing it in a non-adsorbent material, such as glass containing non-agitated air. Such storage inhibited migration and loss of DEHP....

    This study attempts a critical evaluation of the clinical evidence behind the use of dietary pomegranate preparations in the prevention and treatment of cardiovascular diseases. A search of PubMed on August 10, 2014 identified 228 references, which yielded extractable data from 24 clinical studies of pomegranate preparations. Hand searching identified two further studies. The quality of the studies and evidence of effectiveness of pomegranate were assessed by an established set of conventional criteria. Overall, the study quality was poor. Even in the best studies, indications of benefit did not reach the conventional levels of statistical significance. The only study with a definitive design had a biochemical rather than a clinical endpoint: it showed the expected difference in blood concentrations of myeloperoxidase after a single dose of either pomegranate or placebo. Only 10 of the 26 studies provided HPLC data on the amounts of co-active ingredients in the preparations that were consumed by the subjects. If pomegranate has a role in the prevention and treatment of cardiovascular diseases, there is a pressing need for dose-finding and long-term confirmatory studies. The ultimate endpoint for definitive studies would be mortality, but reductions in blood pressure or demonstrable decreases in atherosclerotic plaques would be useful surrogates. Sample sizes for various assumptions are provided. Future studies need to prove the clinical benefit. Copyright © 2015 John Wiley & Sons, Ltd.

    Inflammatory bowel disease (IBD) comprising of ulcerative colitis (UC) and Crohn's disease (CD) is a major ailment affecting the small and large bowel. In clinics, IBD is treated using 5-amninosalicylates, antibiotics, the steroids and immunomodulators. Unfortunately, the long term usages of these agents are associated with undue side effects and compromise the therapeutic advantage. Accordingly, there is a need for novel agents that are effective, acceptable and non toxic to humans. Preclinical studies in experimental animals have shown that curcumin, an active principle of the Indian spice turmeric (Curcuma longa Linn) is effective in preventing or ameliorating UC and inflammation. Over the last few decades there has been increasing interest in the possible role of curcumin in IBD and several studies with various experimental models of IBD have shown it to be effective in mediating the inhibitory effects by scavenging free radicals, increasing antioxidants, influencing multiple signaling pathways, especially the kinases (MAPK, ERK), inhibiting myeloperoxidase, COX-1, COX-2, LOX, TNF-α, IFN-γ, iNOS; inhibiting the transcription factor NF-κB. Clinical studies have also shown that co-administration of curcumin with conventional drugs was effective, to be well-tolerated and treated as a safe medication for maintaining remission, to prevent relapse and improve clinical activity index. Large randomized controlled clinical investigations are required to fully understand the potential of oral curcumin for treating IBD.

    Mild Cognitive Impairment (MCI) affects 25% of older African Americans and predicts progression to Alzheimer's disease. An extensive epidemiologic literature suggests that cognitive, physical, and/or social activities may prevent cognitive decline. We describe the methods of a randomized clinical trial to test the efficacy of Behavior Activation to prevent cognitive decline in older African Americans with the amnestic multiple domain subtype of MCI. Community Health Workers deliver 6 initial in-home treatment sessions over 2-3 months and then 6 subsequent in-home booster sessions using language, materials, and concepts that are culturally relevant to older African Americans during this 24 month clinical trial. We are randomizing 200 subjects who are recruited from churches, senior centers, and medical clinics to Behavior Activation or Supportive Therapy, which controls for attention. The primary outcome is episodic memory as measured by the Hopkins Verbal Learning Test-Revised at baseline and at months 3, 12, 18, and 24. The secondary outcomes are general and domain-specific neuropsychological function, activities of daily living, depression, and quality-of-life. The negative results of recent clinical trials of drug treatments for MCI and Alzheimer's disease suggest that behavioral interventions may provide an alternative treatment approach to preserve cognition in an aging society.

Pp. 232-237 Abstract - Coarse woody debris (CWD) is an important structural component of southern forest ecosystems. CWD loading may be affected by different decomposition rates on sites of varying quality. Bolts of red oak and loblolly pine were placed on plots at each of three (hydric, mesic. and xerlc) sites at the Savannah River Site and sampled over a I6-week period. Major changes were in moisture content and nonstructural carbohydrate content (total carbohydrates, reducing sugars, and starch) of sapwood. Early changes in nonstructural carbohydrate levels following placement of the bolts were likely due to reallocation of these materials by sapwood parenchyma cells. These carbohydrates later formed pools increasingly metabolized by bacteria and invading fungi. Most prevalent fungi in sapwood were Ceratocysfis spp. in pine and Hypoxy/on spp. in oak. Although pine sapwood became blue stained and oak sapwood exhibited yellow soft decay with black zone lines, estimators of decay (specific gravity, sodium hydroxide solubility, and holocellulose content) were unchanged during the 16-week study period. A small effect of site was detected for starch content of sapwood of both species. Fungal biomass in sapwood of both species, as measured by ergosterol content, was detectable at week zero, increased somewhat by week three and increased significantly by week 16.

    Background: Contrast induced nephropathy (CIN) is a serious but rare complication following contrast based procedures. Sodium bicarbonate (NaHCO{sub 3}) has been postulated to prevent CIN by various mechanisms. However, the outcomes following sodium bicarbonate administration to prevent CIN have been inconsistent. Methods: A meta-analysis of published randomized clinical trials to determine if the administration of sodium bicarbonate is superior to sodium chloride among patients with chronic renal failure undergoing catheterization and interventional procedures in preventing CIN was performed. Results: Data were combined across seven published clinical trials consisting of 1734 patients. There were no significant differences in the baseline characteristics between the NaHCO{sub 3} and NaCl groups except patients in the bicarbonate group were heavier (P = 0.04). The odds ratio (OR) for the development of contrast nephropathy for NaHCO{sub 3} versus NaCl was 0.33 (95% confidence interval [CI] 0.16-0.69; P = 0.003). Heterogeneity and publication bias were detectable with P-values 0.01 and 0.0005 respectively. There was no difference between the NaHCO{sub 3} group and the NaCl group in the occurrence of death [OR 0.6; 95% CI (0.26-1.41); P = 0.24], congestive heart failure [OR 0.85; 95% CI (0.32-2.24); P = 0.74] and the requirement for renal replacement therapy [OR 0.56; 95% CI (0.22-1.41); P = 0.22]. Conclusion: This meta-analysis demonstrates that based on currently available randomized trials, the administration of NaHCO{sub 3} is superior to the administration of NaCl alone in the prevention of CIN among patients with moderate to severe chronic kidney disease. However, further controlled clinical trials are needed due to significant study heterogeneity and publication bias.

    Despite recommendations from professional societies and patient safety organizations, the majority of ICU patients worldwide are not routinely monitored for delirium, thus preventing timely prevention and management. The purpose of this systematic review is to summarize what types of implementation strategies have been tested to improve ICU clinicians' ability to effectively assess, prevent and treat delirium and to evaluate the effect of these strategies on clinical outcomes. We searched PubMed, Embase, PsychINFO, Cochrane and CINAHL (January 2000 and April 2014) for studies on implementation strategies that included delirium-oriented interventions in adult ICU patients. Studies were suitable for inclusion if implementation strategies' efficacy, in terms of a clinical outcome, or process outcome was described. We included 21 studies, all including process measures, while 9 reported both process measures and clinical outcomes. Some individual strategies such as "audit and feedback" and "tailored interventions" may be important to establish clinical outcome improvements, but otherwise robust data on effectiveness of specific implementation strategies were scarce. Successful implementation interventions were frequently reported to change process measures, such as improvements in adherence to delirium screening with up to 92%, but relating process measures to outcome changes was generally not possible. In meta-analyses, reduced mortality and ICU length of stay reduction were statistically more likely with implementation programs that employed more (six or more) rather than less implementation strategies and when a framework was used that either integrated current evidence on pain, agitation and delirium management (PAD) or when a strategy of early awakening, breathing, delirium screening and early exercise (ABCDE bundle) was employed. Using implementation strategies aimed at organizational change, next to behavioral change, was also associated with reduced mortality

    Pulmonary tuberculosis is one of the infectious diseases that has been known and is still the leading cause of death in the world. It is an old disease which is a global problem in the world and estimated that a third of the world's population has been infected by this bacterium. The purpose of this study was to determine the factors related with the infection prevention efforts of pulmonary tuberculosis patients in the local goverment clinic of Kuta Baro Aceh Besar. This research is descriptive analytic survey using cross sectional design. It used univariate analysis to see the frequency distribution and the percentage of each variable. Meanwhile, the bivariate analysis used chi square test with CI (Confident Interval) of 95%. The samples in this study are 34 people. The research results obtained with good infection prevention efforts of pulmonary tuberculosis is 41.2%, 5.9% for teenagers, 47.1% for knowledgeable people, 17.6% for people who do not work and 44.1% for those who have a positive behavior. The results of the bivariate obtained there is correlation between the prevention of pulmonary tuberculosis infection with age (p = 0.087), Occupation (p = 0.364), knowledge (p = 0.006) and behavior (p = 0.020). To conclude, there is a correlation between knowledge and behaviors with the infection prevention efforts of pulmonary tuberculosis patients and there is no correlation between age and occupation with infection prevention efforts of pulmonary tuberculosis patients. It is expected that the respondents to hold consultations to health officials about a mechanism of prevention to avoid the disease.

    There are approximately 2000 mobile health clinics operating in the United States. While researchers have established that mobile health clinics can be cost effective and improve outcomes, there is scant research examining the healthcare experience on a mobile health clinic from patients' perspectives. Data were gathered from interviews with 25 clients receiving care on a Boston-based mobile health clinic and analyzed using grounded theory methodology. Emerging patterns in the data revealed three relational and three structural factors most significant to participants' experience of care on The Family Van. Relational factors include providers who 1) Communicate understandably, 2) Create a culture of respect and inclusivity, and 3) Are diverse with knowledge of the community. Structural factors include 1) A focus on preventative health and managing chronic disease, 2) Expeditious, free, and multiple services, and 3) Location. The participant accounts in this report serve to expand on prior research exploring mobile health clinics' role in patients' healthcare, to more clearly define the most salient aspects of the mobile health clinic model for the patients they serve, and to give voice to patients too seldom heard in the academic literature.

During the formative research phase, we conducted a modification of the Priorities for Local AIDS Control Efforts (PLACE method and used those data and staff experiences to identify and prioritize for recruitment geographic areas where HIV incidence might be high. During the clinical trial, we implemented a routinely monitored and flexible recruitment plan in the geographical areas identified in the formative research. We describe three lessons learnt from implementing this approach: 1 the PLACE data were critical in identifying places presumed to be high risk; 2 staff experiences, in combination with PLACE data, were needed to inform a practical recruitment strategy; and 3 recruiting in establishments in priority areas identified by the PLACE data led to screening many HIV-positive women at the Bondo site (Kenya, placing additional burden on clinic staff. These lessons learnt highlight the critical importance of having a flexible and monitored recruitment strategy. Although we successfully recruited a study population at higher risk for HIV, FEM-PrEP was unable to determine the effectiveness of FTC/TDF for HIV prevention, due to low adherence to the study product among participants.

    The purpose of this pilot study was to test the feasibility of a wireless 5-sensor, motion detection system (5S-MDS) with hospitalized older adults. Interventions to prevent hospital-based falls in older adults are important to reduce morbidity, mortality, and health care costs. Wearable motion sensors, which track and wirelessly transmit body movements, may identify human movement patterns that immediately precede falls, thus allowing early prevention. Descriptive feasibility study in which 5 hospitalized older adults were recruited to wear the 5S-MDS for 4 hours. Measurement included assessment of participant acceptance, skin integrity, and sensor accuracy. All 5 participants (mean age, 90.2 years) agreed that sensors were acceptable and skin integrity was maintained. The sensor data accurately reflected the patient movements. The 5S-MDS was feasible for 4 hours' use with hospitalized older adults. It has potential as an early warning system for falls. Copyright © 2012 Mosby, Inc. All rights reserved.

    In this four-year follow up in vivo controlled study, 112 human permanent first molars, from children between the ages of 6 and 11 years old were used to investigate the viability of the CO2 laser in promoting carie-free occlusal surfaces in permanent molars, as an isolated form of treatment or associated with conventional fissure sealants. The findings suggest that occlusal caries prevention only by means of CO2 laser irradiation is not effective; that the utilization of photo-activated sealants, as well as its association with CO2 laser, applied over the occlusal fissures, are effective means of preventing occlusal caries and that the application of CO2 laser over occlusal fissures, prior to the application of a photo-activated fissure sealant, improves the retention of the sealant.

    Sodium-glucose cotransporter 2 (SGLT2) inhibitors are the newest class of antihyperglycemic agents available on the market. Regulator warnings and concerns regarding the risk of developing diabetic ketoacidosis (DKA), however, have dampened enthusiasm for the class despite the combined glycemic, blood pressure, and occasional weight benefits of SGLT2 inhibitors. With the goal of improving patient safety, a cross-Canada expert panel and writing group were convened to review the evidence to-date on reported SGLT2 inhibitor-related DKA incidents and to offer recommendations for preventing and recognizing patients with SGLT2 inhibitor-associated DKA. Reports covering DKA events in subjects taking SGLT2 inhibitors that were published in PubMed, presented at professional conferences, or in the public domain from January 2013 to mid-August 2016 were reviewed by the group independently and collectively. Practical recommendations for diagnosis and prevention were established by the panel. DKA is rarely associated with SGLT2 inhibitor therapy. Patients with SGLT2 inhibitor-associated DKA may be euglycemic (plasma glucose level diabetes, including those with type 2 diabetes, and is typically precipitated by insulin omission or dose reduction, severe acute illness, dehydration, extensive exercise, surgery, low-carbohydrate diets, or excessive alcohol intake. SGLT2 inhibitor-associated DKA may be prevented by withholding SGLT2 inhibitors when precipitants develop, avoiding insulin omission or inappropriate insulin dose reduction, and by following sick day protocols as recommended. Preventive strategies should help avoid SGLT2 inhibitor-associated DKA. All SGLT2 inhibitor-treated patients presenting with signs or symptoms of DKA should be suspected to have DKA and be investigated for DKA, especially euglycemic patients. If DKA is diagnosed, SGLT2 inhibitor treatment should be stopped, and the DKA should be treated with a traditional treatment protocol. Copyright © 2016 Elsevier

    Full Text Available Objective. To investigate motivational factors and barriers to participating in fall risk assessment and management programs among diverse, low-income, community-dwelling older adults who had experienced a fall. Methods. Face-to-face interviews with 20 elderly who had accepted and 19 who had not accepted an invitation to an assessment by one of two fall prevention programs. Interviews covered healthy aging, core values, attributions/consequences of the fall, and barriers/benefits of fall prevention strategies and programs. Results. Joiners and nonjoiners of fall prevention programs were similar in their experience of loss associated with aging, core values they expressed, and emotional response to falling. One difference was that those who participated endorsed that they “needed” the program, while those who did not participate expressed a lack of need. Conclusions. Interventions targeted at a high-risk group need to address individual beliefs as well as structural and social factors (transportation issues, social networks to enhance participation.

    Feigal, R J

    1998-01-01

    Sealants are effective caries-preventive agents to the extent they remain bonded to teeth. Preventive resin restorations (PRR) have a proven record, but are susceptible to failure as the overlying sealant fails. Careful analyses of studies reveal a measurable failure rate of sealants (5-10% per year) that must be addressed. Even under the best of circumstances, sealants fail. Therefore, dentistry (as well as third-party systems) must accept that sealants need vigilant recall and proper preventive maintenance. In addition, it is clear that cost-effective use of sealants will involve selective application on teeth with the greatest caries risk. Caries risk analysis of the patient as well as the tooth is an essential step in the treatment planning process. To improve sealant success, new material advances are suggested. Data from studies using an intermediate layer of dentin bonding agent between etched enamel and sealant show dramatic reduction of failure for sealants, particularly in instances of molars judged difficult to seal due to early stage of eruption.

    In preparation for randomised controlled trials (RCTs) of disease‐modifying antirheumatic drugs in patients with early inflammatory arthritis (EIA), formative research was conducted to enhance the design of such trials. The objectives of this research were to (1) determine patients' educational needs as they relate to the necessary elements of informed consent; and (2) assess patients' interest in enrolling in a hypothetical prevention trial. In‐depth interviews were conducted with nine patients. Seven patients were women and all but one white. The mean age was 48 years. During the 4‐month enrolment period, only three patients with EIA were identified; six patients with longer duration of symptoms were also interviewed. Most patients were able to express the primary aim of a hypothetical prevention trial presented. Factors cited by patients favouring enrolment were potential for direct medical benefit and knowledge that they would be withdrawn from the trial if they developed symptoms. Factors cited by patients against enrolment were the inclusion of a placebo and general uncertainty regarding treatment required by the RCT design. Pending larger‐scale empirical projects to explore patients' attitudes about prevention trials, small‐scale formative research in advance of such trials ought to be conducted. PMID:16984939

    Full Text Available Introduction. Hypothyroidism is often accompanied with decline of kidney function, or inability to maintain electrolyte balance. These changes are usually overlooked in everyday practice. Early recognition of this association eliminates unnecessary diagnostic procedures that postpone the adequate treatment. Case report. Two patients with elevated serum creatinine levels due to primary autoimmune hypothyroidism, with complete recovery of creatinine clearance after thyroid hormone substitution therapy are presented. The first patient was a young male whose laboratory tests suggested acute renal failure, and the delicate clinical presentation of reduced thyroid function. The second patient was an elderly woman with a history of a long-term signs and symptoms attributed to ageing, including the deterioration of renal function, with consequently delayed diagnosis of hypothyroidism. Conclusion. Serum thyrotropin and thyroxin levels measurement should be done in all cases of renal failure with undefined renal desease, even if the typical clinical presentation of hypothyroidism is absent. Thyroid hormone assays sholud also be performed in all patients with chronic kidney disease whose kidney function is rapidly worsening.

    Disclosure of HIV serostatus by HIV-infected individuals is considered a prevention strategy, under the assumption that disclosure will prompt risk reduction practices among sex partners. We examined patients' self-reports regarding disclosure messages they found relevant as part of prevention with positives (PwP) interventions in clinical settings. We conducted 52 in-depth interviews with patients participating in 13 PwP interventions. We found that the opportunity to reflect about living with HIV, explore fears of stigma and rejection, develop communication skills and strategies to disclose, and explore a sense of responsibility influenced patients' intention to disclose and their disclosure practices. PwP interventions need to include a combination of messages about disclosure strategies, stigma, and communication, as well as helping patients frame disclosure as a process that includes situations and interactions to consider post-disclosure. PwP disclosure counseling can help influence a shift in patients' risk towards safer sex practices.

    This study aimed to estimate the effectiveness of L-arginine for preventing preeclampsia in high-risk pregnancy. We performed a randomized, double-blind, placebo-controlled, clinical trial in patients with high-risk factors for preeclampsia. Fifty subjects received L-arginine, beginning from the 20th week of gestation. An additional 50 patients received homologated placebo. The placebo group had a higher number of cases of preeclampsia (11/47) compared with the L-arginine group (3/49, P = 0.01). Birth weight was higher in the L-arginine group and there was a smaller number of preterm births (P = 0.03). L-arginine is effective for preventing preeclampsia.

    To determine whether a viscoelastic polymer (energy absorbing) foam mattress was superior to a standard hospital mattress for pressure ulcer prevention and to analyze the cost-effectiveness in comparison with standard hospital mattresses. Unblinded, randomized, prospective trial. Elderly acute care, rehabilitation, and orthopedic wards at 3 hospitals in the United Kingdom. 1168 patients at risk of developing pressure ulcers (Waterlow score, 15 to 20), with a median age of 83 years (25th to 75th percentile range, 79-87). Participants were allocated to either the experimental equipment (CONFOR-Med mattress/cushion combination) or a standard mattress/cushion combination; all were given standard nursing care. Pressure areas were observed daily. Development of nonblanching erythema. A significant decrease in the incidence of blanching erythema (26.3% to 19.9%; P =.004) and a nonsignificant decrease in the incidence of nonblanching erythema occurred in participants allocated to the experimental equipment. However, when the survival curve plots were analyzed at 7 days, both categories showed statistically significant decreases (P =.0015 and P =.042, respectively). Participants on standard equipment had a relative odds ratio of 1.36 (95% confidence interval [CI], 1.10-1.69) for developing blanching erythema or worse and 1.46 (95% CI, 0.90-1.82) for developing nonblanching erythema or worse. To prevent nonblanching erythema, the number needed to treat (NNT) was 41.9 (95% CI, -82.6-15.3). To prevent any erythema (blanching or nonblanching), the NNT was 11.5 (95% CI, 41.6-9.3). Participants with blanching or nonblanching erythema were significantly less mobile than participants with normal skin and more likely to have worsening mobility (P pressure ulcer status, mattress type was not associated with difference in mobility. Regardless of prevention routine, pressure ulcers occur. In this study, the experimental equipment showed statistical significance to standard equipment

    Delay in recognizing clinical deterioration in acutely unwell patients often leads to cardiac arrests and unexpected admissions to the Intensive Care Unit. Early Warning Scoring Systems based on vital physiological parameters help in early detection of clinical deterioration. When combined with a system of prompt and appropriate clinical response, they have been shown to improve outcome. A standardised National Early Warning Score has been implemented in the United Kingdom. There is a need to implement an early warning scoring system in hospitals in India in order to ensure effective and judicious utilization of our overburdened acute services and to minimize adverse outcomes. © Journal of the Association of Physicians of India 2011.

    The aim of this study was to identify the impact of antifungal prevention in critically ill immunocompetent adult patients on mortality and subsequent infection. A systematic review and meta-analysis of randomized controlled trials comparing any antifungal use versus placebo to prevent candidiasis in ICU patients were performed. Searches were performed on PubMed, Embase, Scopus, main conference proceedings, and ClinicalTrials.gov, as well as reference lists. The primary outcomes were mortality and invasive candidiasis. The secondary outcome was the rate of Candida albicans and nonalbicans strains after treatment. A random effect model was used, and sensitivity analysis was performed for both outcomes. Results are expressed as risk ratios and their 95% CIs. Nineteen trials (10 with fluconazole, four with ketoconazole, one with itraconazole, three with micafungin, and one with caspofungin) including 2,792 patients were identified. No individual trial showed a decreased mortality rate. Combined analysis showed that preventive antifungal did not decrease mortality (risk ratio, 0.88; 95% CI, 0.74-1.04; p = 0.14) but significantly decreased secondary fungal infections by 50% (risk ratio, 0.49; 95% CI, 0.35-0.68; p = 0.0001). No shift across nonalbicans strains was observed during treatment (risk ratio, 0.62; 95% CI, 0.19-1.97; p = 0.42). However, publication biases preclude any definite conclusions for prevention of infection. Antifungal prevention of systemic candidiasis in immunocompetent critically ill adults did not reduce mortality and may have decreased secondary fungal infection rates. However, significant publication bias was present.

    Previous studies have reached conflicting conclusions regarding the efficacy of mesalazine in the prevention of recurrent diverticulitis. To investigate the efficacy and safety of mesalazine granules in the prevention of recurrence of diverticulitis after acute uncomplicated diverticulitis. Two phase 3, randomised, placebo-controlled, double-blind multicentre trials (SAG-37 and SAG-51) investigated mesalazine granules in patients with prior episodes (diverticulitis. Patients were randomised to receive either 3 g mesalazine once daily or placebo (SAG-37, n=345) or to receive either 1.5 g mesalazine once daily, 3 g once daily or placebo for 96 weeks (SAG-51, n=330). The primary endpoint was the proportion of recurrence-free patients during 48 weeks (SAG-37 and SAG-51) or 96 weeks (SAG-51) of treatment. Mesalazine did not increase the proportion of recurrence-free patients over 48 or 96 weeks compared to placebo. In SAG-37, the proportion of recurrence-free patients during 48 weeks was 67.9% with mesalazine and 74.4% with placebo (P=.226). In SAG-51, the proportion of recurrence-free patients over 48 weeks was 46.0% with 1.5 g mesalazine, 52.0% with 3 g mesalazine and 58.0% with placebo (P=.860 for 3 g mesalazine vs placebo) and over 96 weeks 6.9%, 9.8% and 23.1% respectively (P=.980 for 3 g mesalazine vs placebo). Patients with only one diverticulitis episode in the year prior to study entry had a lower recurrence risk compared to >1 episode. Safety data revealed no new adverse events. Mesalazine was not superior to placebo in preventing recurrence of diverticulitis. © 2017 The Authors. Alimentary Pharmacology and Therapeutics published by John Wiley & Sons Ltd.

Among the preventive treatments performed, it has been reported that laser irradiation combined with topical fluoride can induce an even greater increase in enamel caries resistance. The aim of this study was to evaluate the Nd:YAG laser, with or without fluoride, in occlusal caries prevention of the primary dentition. A double-blind split-mouth study design was used. Fifty-two children with high caries risk (7.6 ± 1.4 years) were selected and received the following: G1--the first molar was a negative control, and the second received a resin sealant; G2--the first molar was a negative control, and the second received laser irradiation (50 mJ, 10 Hz, 0.5 W); G3--the first molar received only acidulate phosphate fluoride (APF), and the second received APF + laser; G4--fisrt molar received only fluoride varnish, and the second received fluoride varnish + laser. Patients were followed up to 12 months to evaluate the presence of white-spot lesions and/or caries cavities by three calibrated observers. Thirty-five patients completed the study. Significant differences were found between the treatment and control groups (p laser-alone and resin sealant resulted in statistically lower caries formation than the negative control group (p laser irradiation in primary teeth effectively prevented occlusal caries in pits and fissures when used alone with lower energy over a 1-year period.

    Falls in older adults are the result of several risk factors across biological and behavioral aspects of the person, along with environmental factors. Falls can trigger a downward spiral in activities of daily living, independence, and overall health outcomes. Clinicians who care for older adults should screen them annually for falls. A multifactorial comprehensive clinical fall assessment coupled with tailored interventions can result in a dramatic public health impact, while improving older adult quality of life. For community-dwelling older adults, effective fall prevention has the potential to reduce serious fall-related injuries, emergency room visits, hospitalizations, institutionalization, and functional decline.

    Full Text Available Objectives. Rates of negative laparotomy (NL for acute appendicitis have been reported as 15% and parasitosis contributed to 2%. This study was planned to reduce the rates of NL by preoperative determination of parasitosis. Methods. In retrospective examination of 2730 appendectomy specimens in Hitit University Department of General Surgery between 2008 and 2012, 55 patients were determined with parasitosis and compared with 102 age-matched randomly selected patients with lymphoid hyperplasia. Results. The parasite group comprised 63.6% females with a mean age of 15.1 years. The number of patients in the parasitosis group increased from city centre to rural areas of towns and villages (p2.2% was determined as a diagnostic value. Conclusion. It is important to determine parasitosis to prevent NL. When acute appendicitis is considered for young patients living in rural areas, the observation of high eosinophil together with negative sonographic findings should bring Enterobius vermicularis parasitosis to mind and thereby should prevent NL.

    Full Text Available We aimed to investigate the preventive effects of acupuncture for complications after radical hysterectomy. A single-center randomized controlled single-blinded trial was performed in a western-style hospital in China. One hundred and twenty patients after radical hysterectomy were randomly allocated to two groups and started acupuncture from sixth postoperative day for five consecutive days. Sanyinjiao (SP6, Shuidao (ST28, and Epangxian III (MS4 were selected with electrical stimulation and Zusanli (ST36 without electrical stimulation for thirty minutes in treatment group. Binao (LI14 was selected as sham acupuncture point without any stimulation in control group. The main outcome measures were bladder function and prevalence of postoperative complications. Compared with control group, treatment group reported significantly improved bladder function in terms of maximal cystometric capacity, first voiding desire, maximal flow rate, residual urine, and bladder compliance, and decreased bladder sensory loss, incontinence, and urinary retention on fifteenth and thirtieth postoperative days. Treatment group showed significant advantage in reduction of urinary tract infection on thirtieth postoperative day. But no significant difference between groups was observed for lymphocyst formation. By improving postoperative bladder function, early intervention of acupuncture may provide a valuable alternative method to prevent bladder dysfunctional disorders and urinary tract infection after radical hysterectomy.

    The newly gained knowledge of the viral etiology in cervical carcinogenesis has prompted industrial interests in developing virology-based tools for cervical cancer prevention. Due to the long incubation period from viral infection to developing an invasive cancer, a process whose outcome is influenced by numerous life-style and genetic factors, the true efficacy of the genotype-specific human papillomavirus (HPV) vaccines in cervical cancer prevention cannot be determined for another 30 years. Most HPV DNA test kits designed to replace the traditional Papanicolaou (Pap) smears for precancer detection lack the analytical sensitivity and specificity to comprehensively detect all potentially carcinogenic HPVs and to perform reliable genotyping. The authors implemented the classic nested PCR and Sanger DNA-sequencing technology for routine HPV testing. The results showed a true negative HPV PCR invariably indicates the absence of precancerous cells in the cytology samples. However, 80.5% of single positive HPV-16 tests and 97.3% of single positive HPV-18 tests were associated with a negative or a largely self-reversible Pap cytology. Routine sensitive and reliable HPV type-specific or perhaps even variant-specific methods are needed to address the issues of persistence of HPV infection if a virology-based primary cervical screen is used to replace the Pap cytology screening paradigm

    Patients with diabetes need a complex set of services and supports. The challenge of integrating these services into the diabetes regimen can be successfully overcome through self-management support interventions that are clinically linked and technology enabled: self-management support because patients need help mastering the knowledge, attitudes, skills, and behaviors so necessary for good outcomes; interventions because comprehensive theory-based, evidence-proven, long-term, longitudinal interventions work better than direct-to-consumer or nonplanned health promotion approaches; clinically linked because patients are more likely to adopt new behaviors when the approach is in the context of a trusted therapeutic relationship and within an effective medical care system; and technology enabled because capitalizing on the amazing power of information technology leads to the delivery of cost-effective, scalable, engaging solutions that prevent and manage diabetes. © 2011 Diabetes Technology Society.

    The American Society of Clinical Oncology (ASCO) has a policy and set of procedures for endorsing recent clinical practice guidelines that have been developed by other professional organizations. The Cancer Care Ontario (CCO) Guideline on Follow-up Care, Surveillance Protocol, and Secondary Prevention Measures for Survivors of Colorectal Cancer was reviewed by ASCO for methodologic rigor and considered for endorsement. The ASCO Panel concurred with the CCO recommendations and recommended endorsement, with the addition of several qualifying statements. Surveillance should be guided by presumed risk of recurrence and functional status of the patient (important within the first 2 to 4 years). Medical history, physical examination, and carcinoembryonic antigen testing should be performed every 3 to 6 months for 5 years. Patients at higher risk of recurrence should be considered for testing in the more frequent end of the range. A computed tomography scan (abdominal and chest) is recommended annually for 3 years, in most cases. Positron emission tomography scans should not be used for surveillance outside of a clinical trial. A surveillance colonoscopy should be performed 1 year after the initial surgery and then every 5 years, dictated by the findings of the previous one. If a colonoscopy was not preformed before diagnosis, it should be done after completion of adjuvant therapy (before 1 year). Secondary prevention (maintaining a healthy body weight and active lifestyle) is recommended. If a patient is not a candidate for surgery or systemic therapy because of severe comorbid conditions, surveillance tests should not be performed. A treatment plan from the specialist should have clear directions on appropriate follow-up by a nonspecialist.

    A simulation program was implemented in a pre-registration nursing curriculum for developing nursing students' performances in assessing, managing and reporting in relation to patients with physiological deterioration. To explore nursing students' experiences of how a simulation programme has prepared them to transfer their performance to clinical practice, in their encounters with deteriorating patients in ward. A qualitative study using a critical incident technique was conducted. After they had undertaken a simulation program, fifteen undergraduate nursing students, who had encountered deteriorating patients in their clinical practicum in wards were interviewed using semi-structured questionnaires. Content analysis was used to analyse the data. Four main themes emerged describing key factors influencing the transfer of simulation learning to clinical practice; memory, involving simulation learning enhanced storage and retrieval of knowledge; mnemonics as transfer tools for performing systematic physical assessment and reporting a patient's deterioration to a doctor; recognizing similar situations, where students used experiences from similar simulation situation to identify problems and initiate nursing interventions for their patients; and finally, emotional responses, that have both negative and positive impacts on transferring their simulation learning. Two other main themes emerged regarding strategies to facilitate transfer; self-directed learning for promoting the retention of simulation learning; and, realism, where simulated patients could be used to provide real-life clinical experiences. The findings provide an understanding of how a simulation program may impact on the nursing students' performances in clinical practice, which is useful information for future improvement of programmes to optimize learning and transfer effective care to patient care settings.

    2017-11-01

    Cardiovascular disease is the leading cause of death among women in the United States. Obstetrician-gynecologists often are the sole health care providers for otherwise healthy women. Therefore, they must be aware of risk factors, signs, and symptoms of cardiovascular disease and be prepared to recognize and treat this condition in patients as well as provide referrals when specialized care is indicated. Women with cardiac problems typically present with chest discomfort; however, they also are more likely than healthy women to present with other common symptoms, such as shortness of breath, back pain, jaw pain, or nausea and vomiting. This monograph, with a primary focus on ischemic heart disease (IHD), discusses the basic anatomy of the heart and coronary arteries; vascular biology; pathogenesis of atherosclerosis; and the screening, prevention, diagnosis, and treatment of IHD as well as the multiple risk factors associated with the development of IHD that contribute to both increased morbidity and mortality.

    Full Text Available At present, tick-borne encephalitis is registered in Siberia, Far East, Urals, Belarus and central regions of Russia. The viral infection has also been recently revealed among the population of the previously problem free regions: Penza, Yaroslavl, Magadan, Kamchatka, Moscow and Ivanovo. The disease manifests itself in various forms: febrile, meningeal, meningoencephalitic etc. The disease prognosis is favorable in case of a meningeal or febrile form, but significantly worse in case of a meningoencephalitic form – fatal outcomes take place in 25-30% of cases. Residuals in the form of convulsive hyperkinetic syndrome may remain in some patients even if the treatment started in time. Active immunization is the primary tick-borne encephalitis prevention.

    2011-01-01

    The clinical importance of radiation-induced heart disease, in particular in post-operative radiotherapy of breast cancer patients, has been recognised only recently. There is general agreement, that a co-ordinated research effort would be needed to explore all the potential strategies of how to reduce the late risk of radiation-induced heart disease in radiotherapy. This approach would be based, on one hand, on a comprehensive understanding of the radiobiological mechanisms of radiation-induced heart disease after radiotherapy which would require large-scale long-term animal experiments with high precision local heart irradiation. On the other hand - in close co-operation with mechanistic in vivo research studies - clinical studies in patients need to determine the influence of dose distribution in the heart on the risk of radiation-induced heart disease. The aim of these clinical studies would be to identify the critical structures within the organ which need to be spared and their radiation sensitivity as well as a potential volume and dose effect. The results of the mechanistic studies might also provide concepts of how to modify the gradual progression of radiation damage in the heart by drugs or biological molecules. The results of the studies in patients would need to also incorporate detailed dosimetric and imaging studies in order to develop early indicators of impending radiation-induced heart disease which would be a pre-condition to develop sound criteria for treatment plan optimisation.

    This revised Clinical Guideline in Paediatric Dentistry replaces the previously published ninth guideline (Shaw L, O'Sullivan E. Int J Paediatr Dent 2000; 10: 356-365). The process of guideline production began in 1994, resulting in first publication in 1997. Each guideline has been circulated widely for consultation to all UK consultants in paediatric dentistry, council members of the British Society of Paediatric Dentistry (BSPD), and to people of related specialities recognized to have expertise in the subject. The final version of this guideline is produced from a combination of this input and thorough review of the published literature. In the case of the present guideline, an internationally recognized expert in the field was invited to be a co-author (AM). The intention is to encourage improvement in clinical practice and to stimulate research and clinical audit in areas where scientific evidence is inadequate. Evidence underlying recommendations is scored according to the SIGN classification and guidelines should be read in this context. Further details regarding the process of paediatric dentistry guideline production in the UK is described in the Int J Paediatr Dent 1997; 7: 267-268.

    Full Text Available OBJECTIVE: To investigate if E-learning material improves the basal student knowledge level before attending the presential class of blindness prevention (BP and if helps to fix this information one-month after the class. METHODS: Fourth-year medical students were randomly assigned to have a presential class of BP (Traditional group = TG or to have a presential class of BP plus an additional E-learning material (E-learning group = ELG. This material was e-mailed one week before the presential class. The students were submitted to a multiple-choice test (with three options each with seven questions immediately before the presential class, immediately after the class, and one-month later. The three tests had the same questions; however, the answers options were distributed in different sequences. The primary outcome was immediate pretest score. The secondary outcomes were immediate posttest score and one-month posttest score. RESULTS: Among the 120 fourth-year medical students, a random sample of 34 students was assigned to the TG and 34 students was assigned to the ELG. The two groups showed similar immediate posttest score (TG=6.8 and ELG=6.9; P<.754, but the differences at the immediate pretest score (TG=3.6 and ELG=4.7; P<.001, and at the one-month posttest score, were significant (TG=6.1 and ELG=6.8; P<.001. CONCLUSIONS: The pretest and the one-month posttest results suggested that the E-learning material acts as an effective complementary tool of the presential class of blindness prevention.

The strict application of the preventive measures can completely prevent the speading occurrence of hepatitis C on haemodialisys.

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

    Directory of Open Access Journals (Sweden)

    S. Taddei

    2013-05-01

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

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

For this decision problem, the risk of failure should be compared to the cost of preventive maintenance. The hypothesis that the maximum pitch motor torque is an indicator of the damage size is supported...... by results from a measurement campaign where measurements are available both before and after maintenance was performed. The loads dramatically decreased after the maintenance. However, after a few more months of measurements, and by including data from the SCADA system, it became obvious that seasonal...

    Full Text Available Retention is critical in HIV prevention programs and clinical research. We studied retention in the three modeled scenarios of primary prevention programs, cohort studies and clinical trials to identify predictors of retention.Men attending Sexually Transmitted Infection (STI clinics (n = 10, 801 were followed in a cohort study spanning over a ten year period (1993-2002 in Pune, India. Using pre-set definitions, cases with optimal retention in prevention program (n = 1286, cohort study (n = 940 and clinical trial (n = 896 were identified from this cohort. Equal number of controls matched for age and period of enrollment were selected. A case control analysis using conditional logistic regression was performed. Being employed was a predictor of lower retention in all the three modeled scenarios. Presence of genital ulcer disease (GUD, history of commercial sex work and living away from the family were predictors of lower retention in primary prevention, cohort study and clinical trial models respectively. Alcohol consumption predicted lower retention in cohort study and clinical trial models. Married monogamous men were less likely to be retained in the primary prevention and cohort study models.Predicting potential drop-outs among the beneficiaries or research participants at entry point in the prevention programs and research respectively is possible. Suitable interventions might help in optimizing retention. Customized counseling to prepare the clients properly may help in their retention.

    The use of proton pump inhibitors for prevention of nonsteroidal anti-inflammatory drug (NSAID)-induced gastrointestinal adverse events is well documented. However, data regarding the efficacy and safety of this approach in Japan are scarce. To evaluate the efficacy and tolerability of esomeprazole in preventing NSAID-induced peptic ulcers in Japanese at-risk patients. Male and female Japanese adult patients (aged ≥ 20 years) with endoscopically confirmed history of peptic ulcers who required long-term oral NSAID therapy for a chronic inflammatory condition were randomised to 24 weeks' treatment with esomeprazole 20 mg once daily or matching placebo. The primary end point was the Kaplan-Meier estimated proportion of ulcer-free patients. Overall, 343 patients were randomised to treatment (esomeprazole, n = 175; placebo, n = 168). The Kaplan-Meier estimated ulcer-free rate over the 24-week treatment period was significantly higher (log-rank P < 0.001) in esomeprazole-treated patients (96.0%; 95% CI 92.8, 99.1) than in placebo recipients (64.4%; 95% CI 56.8, 71.9). Esomeprazole was effective at preventing peptic ulcers in both Helicobacter pylori-positive and -negative patients (96.3% vs. 95.5% of patients ulcer-free, respectively); however, in the placebo group, the proportion of ulcer-free patients at 24 weeks was markedly lower among H. pylori-positive than -negative patients (59.7% vs. 69.9%). The NSAID type did not seem to affect the estimated ulcer-free rate with esomeprazole. Treatment with esomeprazole was well tolerated. Esomeprazole 20 mg once daily is effective and safe in preventing ulcer recurrence in Japanese patients with a definite history of peptic ulcers who were taking an NSAID (ClinicalTrials.gov identifier: NCT00542789). © 2012 Blackwell Publishing Ltd.

    Full Text Available Abstract Background Cardiovascular diseases (CVD are the leading cause of death and the third cause of disability in Europe. Prevention programmes should include interventions aimed at a reduction of medical risk factors (hypertension, hypercholesterol, hyperglycemia, overweight and obesity as well as behavioural risk factors (sedentary lifestyle, high fat intake and low fruit and vegetable intake, smoking. The aim of this study is to investigate the effects of a multifaceted, multidisciplinary electronic prevention programme on cardiovascular risk factors. Methods/Design In a randomized controlled trial, one group will receive a maximal intervention (= intervention group. The intervention group will be compared to the control group receiving a minimal intervention. An inclusion of 350 patients in total, with a follow-up of 3 years is foreseen. The inclusion criteria are age between 25–65 and insured by the Onderlinge Ziekenkas, insuring for guaranteed income in case of illness for self-employed. The maximal intervention group receives several prevention consultations by their general practitioner (GP using a new type of cardiovascular risk calculator with personalised feedback on behavioural risk factors. These patients receive a follow-up with intensive support of health behaviour change via different methods, i.e. a tailored website and personal advice of a multidisciplinary team (psychologist, physiotherapist and dietician. The aim of this strategy is to reduce cardiovascular risk factors according to the guidelines. The primary outcome measures will be cardiovascular risk factors. The secondary outcome measures are cardiovascular events, quality of life, costs and incremental cost effectiveness ratios. The control group receives prevention consultations using a new type of cardiovascular risk calculator and general feedback. Discussion This trial incorporates interventions by GPs and other health professionals aiming at a reduction of

    Prevention intervention trials have been conducted to reduce risk of sexual transmission among people living with HIV/AIDS (PLWHA), but the findings were inconsistent. We performed a systematic review and meta-analysis to evaluate overall efficacy of prevention interventions on unprotected vaginal or anal intercourse (UVAI) among PLWHA from randomized clinical trials (RCTs). RCTs of prevention interventions among PLWHA published as of February 2012 were identified by systematically searching thirteen electronic databases. The primary outcome was UVAI. The difference of standardized mean difference (SMD) of UVAI between study arms, defined as effect size (ES), was calculated for each study and then pooled across studies using standard meta-analysis with a random effects model. Lower likelihood of UVAI was observed in the intervention arms compared with the control arms either with any sexual partners (mean ES: -0.22; 95% confidence interval [CI]: -0.32, -0.11) or with HIV-negative or unknown-status sexual partners (mean ES and 95% CI: -0.13 [-0.22, -0.04]). Short-term efficacy of interventions with ≤ 10 months of follow up was significant in reducing UVAI (1-5 months: -0.27 [-0.45, -0.10]; 6-10 months: -0.18 [-0.30, -0.07]), while long-term efficacy of interventions was weaker and might have been due to chance (11-15 months: -0.13 [-0.34, 0.08]; >15 months: -0.05 [-0.43, 0.32]). Our meta-analyses confirmed the short-term impact of prevention interventions on reducing self-reported UVAI among PLWHA irrespective of the type of sexual partner, but did not support a definite conclusion on long-term effect. It is suggested that booster intervention sessions are needed to maintain a sustainable reduction of unprotected sex among PLWHA in future risk reduction programs.

    Nursing work often occurs in complex and potentially hazardous settings. Awareness of patient and practice environments is an imperative for nurses in practice. To explore nursing students' situation awareness while engaging in simulated patient deterioration scenarios. The educational process of FIRST(2)ACT was the model for the nurse intervention. Situation awareness was measured quantitatively using the Situation Awareness Global Assessment tool. Four domains were measured: physiological perception (patient parameters), global perception (surroundings), comprehension (interpretation of information), and projection (forecasting outcomes). Clinical laboratories at each of three participating universities. Ninety-seven nursing students from three Australian universities. Between March and July 2012, students participated in three video-recorded simulation events, in which a trained actor played patient roles and groups of three students worked as teams. To measure situation awareness, following the simulation each team leader was taken to a separate room and asked to report on a question set regarding the patient's vital signs, bedside setting and medical diagnosis. Overall, situation awareness was low (41%). Of the four domains, physiological perceptions scored the lowest (26%) and projection the highest (59%). Final year nursing students may not have well developed situation awareness skills, especially when dealing with these types of scenarios. Education providers need to consider ways to assist students to fully develop this attribute. Findings suggest that this is an aspect of undergraduate nursing education that requires significant consideration by curriculum developers. Crown Copyright © 2014. Published by Elsevier Ltd.

    The feet of diabetic patients continue to be an unsolved problem in medicine. Uncontrolled neuropathy, ulceration and infection usually lead to amputation and presently there is no effective and reliable method that can be used to provide an efficient cure. Overall improvement in the salvage strategies, based on comprehensive pre-clinical evaluation, debridement, antibiotic therapy and follow up, has shown improvements in certain hospital settings, but the general picture for patients with diabetic foot is to have some sort of amputation, especially in underserved populations. It is clearly necessary to develop novel treatment strategies for this worldwide health problem. Photodynamic therapy (PDT) is a treatment modality that uses light to generate in situ reactive oxygen species, which can cause cell death. PDT can be used to treat several diseases, including foot infections that do not respond well to antibiotic therapy. There are several characteristics of PDT that make it potentially ideal to treat diabetic feet: the photosensitizer is non-toxic in the dark, but after illumination it becomes a very efficient antimicrobial agent with topical use, and it can regenerate small bones, such as the phalanges. However, PDT is still not used in clinical practice to treat diabetic feet. Therefore, we decided to perform a clinical study to prove that PDT is an effective method to avoid amputation of infected diabetic feet. An inexpensive PDT protocol was developed and applied to 18 patients with osteomyelitis, classified as Grade 3 on the Wagner scale. Only one of these patients suffered amputation. At least two of them were cured from resistant bacteria strains without intravenous antibiotic therapy. In the control group of 16 patients, all of them ended up suffering amputation. The rate of amputation in the PDT group was 0.029 times the rate in the control group and the difference is clearly statistically significant (p=0.002). Copyright © 2014 Elsevier B.V. All

    Full Text Available The HIV epidemic in the United States (US disproportionately affects gay, bisexual, and other men who have sex with men (MSM. Pre-exposure prophylaxis (PrEP using co-formulated tenofovir disoproxil fumarate (TDF and emtricitabine (FTC has demonstrated high efficacy in reducing HIV incidence among MSM. However, low adherence was reported in major efficacy trials and may present a substantial barrier to successful PrEP implementation. Rates of adherence to PrEP in "real-world" clinical settings in the US remain largely unknown.We reviewed demographic and clinical data for the first 50 patients to enroll in a clinical PrEP program in Providence, Rhode Island. We analyzed self-reported drug adherence as well as drug concentrations in dried blood spots (DBS from patients who attended either a three- or six-month follow-up appointment. We further assessed drug concentrations and the resistance profile of a single patient who seroconverted while taking PrEP.Of the first 50 patients to be prescribed PrEP, 62% attended a follow-up appointment at three months and 38% at six months. Of those who attended an appointment at either time point (70%, n = 35, 92% and 95% reported taking ±4 doses/week at three and six months, respectively. Drug concentrations were performed on a random sample of 20 of the 35 patients who attended a follow-up appointment. TDF levels consistent with ±4 doses/week were found in 90% of these patients. There was a significant correlation between self-reported adherence and drug concentrations (r = 0.49, p = 0.02. One patient who had been prescribed PrEP seroconverted at his three-month follow-up visit. The patient's drug concentrations were consistent with daily dosing. Population sequencing and ultrasensitive allele-specific PCR detected the M184V mutation, but no other TDF- or FTC-associated mutations, including those present as minor variants.In this clinical PrEP program, adherence was high, and self-reported drug adherence

    ICUs are a major reservoir of methicillin-resistant Staphylococcus aureus. Our aim was to estimate costs and effectiveness of methicillin-resistant Staphylococcus aureus prevention policies. We evaluated three up-to-date methicillin-resistant Staphylococcus aureus prevention policies, namely, 1) nasal screening and contact precautions of methicillin-resistant Staphylococcus aureus-positive patients; 2) nasal screening, contact precautions, and decolonization (targeted decolonization) of methicillin-resistant Staphylococcus aureus carriers; and 3) universal decolonization without screening. We implemented a decision-analytic model with deterministic and probabilistic analyses. Methicillin-resistant Staphylococcus aureus infections averted, quality-adjusted life years gained, and incremental cost-effectiveness ratios were calculated. Cost-effectiveness planes and acceptability curves were plotted for various willingness-to-pay thresholds to address uncertainty. At base-case scenario, universal decolonization was the dominant strategy; it averted 1.31% and 1.59% of methicillin-resistant Staphylococcus aureus infections over targeted decolonization and screening and contact precautions, respectively, and saved $16,203/quality-adjusted life year over targeted decolonization and 14,562/quality-adjusted life year over screening and contact precautions. Results were robust in sensitivity analysis for a wide range of input variables. In probabilistic analysis, universal decolonization increased quality-adjusted life years by 1.06% (95% CI, 1.02-1.09) over targeted decolonization and by 1.29% (95% CI, 1.24-1.33) over screening and contact precautions; universal decolonization resulted in average savings of $172 (95% CI, $168-$175) and $189 (95% CI, $185-$193) over targeted decolonization and screening and contact precautions, respectively. With willingness-to-pay threshold per quality-adjusted life year gained ranging from $0 to $50,000, universal decolonization was dominant

    Full Text Available The paper deals with a rare monogenic connective tissue disease from a group of fibrillinopathies with autosomal dominant inheritance — Beals syndrome caused by a mutation in the FBN2 gene. Attention is drawn to the high phenotypic similarity of this disease and Marfan syndrome (FBN1 gene mutation, which is associated with the almost complete identity of two proteins: fibrillin 1 and fibrillin 2.The paper describes a clinical case of a child with Beals syndrome and the typical manifestations of the disease: asthenic constitution, arachnodactyly of the hands and feet, congenital contractures of the large and small joints, chest deformity, kyphoscoliosis, talpes, and crushed ears. The investigators made a differential diagnosis with other connective tissue diseases, such as Marfan syndrome, Stickler syndrome, Ehlers–Danlos syndrome, homocystenuria, and arthrogryposis. DNA diagnosis verified the Beals syndrome in the proband. Exon 28 in the FBN2 gene showed the previously undescribed missense mutation of c.3719G>A, resulting in the amino acid substitution of cysteine for tyrosine (p.Cys1240Tyr in the structure of the protein fibrillin 2. A de novo mutation occurred. There is evidence for its pathogenicity in the development of the clinical symptoms of the disease. The problems of effective medical genetic counseling in this family are discussed.

    2015-02-01

    The diagnosis of rabies encephalitis relies on awareness of the varied clinical features and eliciting a history of unusual contact with a mammal throughout the endemic area. The diagnosis is easily missed. Laboratory tests are not routine and only confirm clinical suspicion. Rabies infection carries a case fatality exceeding 99.9%. Palliation is appropriate, except for previously-vaccinated patients or those infected by American bats, for whom intensive care is probably indicated. However, as rabies vaccines are outstandingly effective, no one should die of dog-transmitted infection. Vaccines and rabies immunoglobulin are expensive and usually scarce in Asia and Africa. All travellers to dog rabies enzootic areas should be strongly encouraged to have pre-exposure immunisation before departure. There is no contraindication to vaccination but the cost can be prohibitive. Intradermal immunisation, using 0.1 ml and sharing vials of vaccine, is cheaper and is now permitted by UK regulations. Returning travellers may need post-exposure prophylaxis. Economical intradermal post-exposure vaccination is practicable and should be introduced into rural areas of Africa and Asia immediately. Eliminating rabies in dogs is now feasible and would dramatically reduce human mortality, if funds were made available. The high current economic burden of human prophylaxis would then be largely relieved. © 2015 Royal College of Physicians.

  14. Mechanisms, prevention and clinical implications of nonsteroidal anti-inflammatory drug-enteropathy

    Wallace, John L

    2013-01-01

    This article reviews the latest developments in understanding the pathogenesis, detection and treatment of small intestinal damage and bleeding caused by nonsteroidal anti-inflammatory drugs (NSAIDs). With improvements in the detection of NSAID-induced damage in the small intestine, it is now clear that this injury and the associated bleeding occurs more frequently than that occurring in the stomach and duodenum, and can also be regarded as more dangerous. However, there are no proven-effective therapies for NSAID-enteropathy, and detection remains a challenge, particularly because of the poor correlation between tissue injury and symptoms. Moreover, recent studies suggest that commonly used drugs for protecting the upper gastrointestinal tract (i.e., proton pump inhibitors) can significantly worsen NSAID-induced damage in the small intestine. The pathogenesis of NSAID-enteropathy is complex, but studies in animal models are shedding light on the key factors that contribute to ulceration and bleeding, and are providing clues to the development of effective therapies and prevention strategies. Novel NSAIDs that do not cause small intestinal damage in animal models offer hope for a solution to this serious adverse effect of one of the most widely used classes of drugs. PMID:23569332

    An investigation was made on the relationship between music practice and musculo-skeletal disorders among piano students, with the main aim of developing health education programmes that would improve the performance and health of the students. The investigation covered three areas: (a) Analysis of study organization and main musculo-skeletal complaints achieved by a questionnaire distributed to all piano students at the Milan Conservatory. (b) Vocational electromyographic analysis of the effort exerted by the various muscle groups of the trunk, of the shoulder and shoulder blade girdle, and of the arm during performance of a standard set of piano exercises, an unseen passage and a passage of maximum difficulty. This analysis was made on a sample of six subjects. (c) A series of preventive measures was developed on the basis of a critical assessment of the results (38% of the students practised for excessively long periods without breaks; 62% had from 1 to 5 complaints, the most affected sites being the spine and the trapezius muscles). These consisted largely of a health education programme aimed at helping the students to suitably organize practice and rest periods and in instructing them in appropriate exercises for relaxation and stretching of overused muscle groups and strengthening the supporting muscle groups. Changes in lifestyle were also suggested.

    Mycophenolate Mofetil (M MF) is a new immunosuppressive agent with proven efficacy for the prevention of kidney allograft rejection. However, only little experience is available with the use of MMF in liver transplant recipients. In this prospective, controlled trial the efficacy and safety of MMF and Azathioprine (AZA) were compared in a Neoral based quadruple immunosuppressive regimen after orthotopic liver transplantation. Between 12/96 and 12/98 57 adult patients were enrolled in the study at the University of Hamburg. 28 patients were randomised to MMF, 29 patients to AZA in combination with equivalent doses of lymphocyte antibodies, Neoral and methylprednisolone. After a median follow-up of 10+/-3.2 months patient or graft survival did not differ significantly between the MMF and AZA group. However, MMF treated patients experienced less frequently acute rejection episodes (MMF: 6/28; 21.4% versus AZA: 13/29; 44.8%) (p=0.06). Furthermore, thrombocytopenia (MMF: 6/28; 21.4% versus AZA: 14/29; 48.3%) (ppreliminary data suggest that after liver transplantation primary immunosuppression with MMF is advantageous over AZA with regard to safety and efficacy.

    Full Text Available M Andrea Markus, Brian J MorrisSchool of Medical Sciences and Bosch Institute, The University of Sydney, Sydney, NSW, AustraliaAbstract: Resveratrol is a potent member of the class of natural, plant-derived chemicals known as polyphenols. These help explain in part why a diet high in fruit and vegetables confers health benefits and are associated with reduced risk of common complex conditions such as cardiovascular disease, cancer, diabetes, and Alzheimer’s disease. We present the latest molecular findings that account for the beneficial actions of resveratrol. The intracellular pathways activated are crucial for anti-oxidant defence, regulation of the cell cycle, mitochondrial energy production, vascular tone, oncogene suppression, and many other phenomena which if unchecked lead to morbidity and mortality from onset and progression of these various diseases. While a healthy diet and lifestyle is strongly recommended in prevention of such conditions, the future bodes well for the use of resveratrol and analogues of higher potency than the natural form for treatment of diseases that afflict humans, particularly as they age.Keywords: resveratrol, longevity, SIRT, wine, aging, cancer

    We sought to document the clinical performance of the 1st American Academy of Orthopaedic Surgeons (AAOS) guideline on the prevention of symptomatic pulmonary embolism (PE) after total knee arthroplasty (TKA) in Korean patients, in terms of the proportions of the each risk-stratified group, efficacy and safety. Consecutive 328 patients underwent TKA were preoperatively assessed for the risks of PE and bleeding and categorized into 4 groups: 1) standard risk, 2) high risk for PE, 3) high risk for bleeding, and 4) high risks both for PE and bleeding. One of three options was administered according to the groups (aspirin in group 1 or 4; enoxaparin and following aspirin in group 2; antithrombotic stocking in group 3). Incidences of symptomatic deep vein thrombosis (DVT) and PE, and major or minor bleeding complications were evaluated. Majority of the patients (86%) were assessed to be with standard risks both for PE and bleeding. No patient experienced symptomatic DVT or PE and major bleeding. Eleven percent of the patients discontinued chemoprophylaxis because of bleeding-related wound complication. In conclusion, the 1st AAOS guideline functions successfully in Korean patients undergoing TKA in terms of prevention of symptomatic DVT and PE while avoiding major bleeding complications.

    Purpose Prime Time, a youth development intervention, aims to reduce pregnancy risk among adolescent girls seeking clinic services who are at high risk for pregnancy. This paper examines sexual risk behaviors and hypothesized psychosocial mediators after 12 months of the Prime Time intervention. Methods Randomized controlled trial with 253 girls ages 13-17 years meeting specified risk criteria. Intervention participants were involved in Prime Time programming plus usual clinic services for 18 months, control participants received usual clinic services. The intervention employed a combination of case management and peer leadership programs. Participants in this interim outcomes study completed self-report surveys at baseline and 12 months following enrollment. Surveys assessed sexual risk behaviors and psychosocial factors targeted for change by Prime Time. Results At the 12-month interim, the intervention group reported more consistent use of condoms, hormonal contraception and dual contraceptive methods with their most recent partner than did the control group. The intervention group also reported greater stress management skills with trends towards higher levels of pro-social connectedness at school and with family. No between-group differences were noted in psychosocial measures specific to sex and contraceptive use. Conclusions Preventing early pregnancy among high-risk adolescents requires multifaceted, sustained approaches. An important research focus involves testing youth development interventions offered through clinic settings, where access to high-risk adolescents is plentiful and few efforts have emphasized a dual approach of building protective factors while addressing risk. Findings suggest that youth development interventions through clinic settings hold promise in reducing pregnancy risk among high-risk youth. PMID:21783050

    In rural India, mobile medical clinics are useful models for delivering health promotion, education, and care. Mobile medical clinics use fewer providers for larger catchment areas compared to traditional clinic models in resource limited settings, which is especially useful in areas with shortages of healthcare providers and a wide geographical distribution of patients. From 2008 to 2011, we built infrastructure to implement a mobile clinic system to educate rural communities about maternal child health, train community health workers in common safe birthing procedures, and provide comprehensive antenatal care, prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV), and testing for specific infections in a large rural catchment area of pregnant women in rural Mysore. This was done using two mobile clinics and one walk-in clinic. Women were tested for HIV, hepatitis B, syphilis, and bacterial vaginosis along with random blood sugar, urine albumin, and anemia. Sociodemographic information, medical, and obstetric history were collected using interviewer-administered questionnaires in the local language, Kannada. Data were entered in Microsoft Excel and analyzed using Stata SE 14.1. During the program period, nearly 700 community workers and 100 health care providers were trained; educational sessions were delivered to over 15,000 men and women and integrated antenatal care and HIV/sexually transmitted infection testing was offered to 3545 pregnant women. There were 22 (0.6%) cases of HIV, 19 (0.5%) cases of hepatitis B, 2 (0.1%) cases of syphilis, and 250 (7.1%) cases of BV, which were identified and treated. Additionally, 1755 (49.5%) cases of moderate to severe anemia and 154 (4.3%) cases of hypertension were identified and treated among the pregnant women tested. Patient-centered mobile medical clinics are feasible, successful, and acceptable models that can be used to provide quality healthcare to pregnant women in rural and

    The aim of this study was to assess if an antiseptic pomade could reduce the bacterial colonization on multifilament sutures. A randomized clinical trial was conducted with 40 volunteer patients of both sexes aged 18-70, randomly separated into experimental (n = 20) and control (n = 20) groups. The experimental group received pomade-coated sutures (iodoform + calendula) and the control group uncoated sutures. Two millimeters of the suture was harvested from each patient from the 1st to the 15th postoperative day. The bacteria that had adhered to them were cultured. The number of colony-forming units per milliliter (CFU/mL) was determined and the groups were compared using the Mann-Whitney statistical test (P antiseptic pomade was effective in reducing bacterial colonization on silk braided sutures.

    Full Text Available Cervical cancer (CC morbidity is analyzed on the basis of the data of the Karelian cancer register over the period 1998-2007. During this period, 816 cases of CC were registered and 126 were found at an antenatal clinic (AC. Its early detection rate was ascertained to be 96% during screening at the AC. A comprehensive examination was made in 1742 women with various cervical diseases, of them 37.5% were infected with human papillomavirus (HPV. High-grade dysplasia and carcinoma in situ were diagnosed in 6.6% of the HPV-infected patients. Large-scale screening for HPV infection and pretumor disorders with their further treatment will aid in reduc- ing CC morbidity and mortality rates.

    2013-01-01

    Health-related information collected in psychological laboratories may not be representative of people's everyday health. For at least 70 years, there has been a call for methods that sample experiences from everyday environments and circumstances. New technologies, including cell phones, sensors, and monitors, now make it possible to collect information outside of the laboratory in environments representative of everyday life. We review the role of mobile technologies in the assessment of health-related behaviors, physiological responses, and self-reports. Ecological momentary assessment offers a wide range of new opportunities for ambulatory assessment and evaluation. The value of mobile technologies for interventions to improve health is less well established. Among 21 randomized clinical trials evaluating interventions that used mobile technologies, more than half failed to document significant improvements on health outcomes or health risk factors. Theoretical and practical issues for future research are discussed.

    2017-12-01

    Full Text Available BACKGROUND Placental cord drainage is a simple, safe and non-invasive method which reduces the duration and blood loss in the third stage of labour thereby preventing PPH. This method is of great use in day to day obstetric practices not requiring any extra effort, cost or equipment, so this type of practice is more relevant in rural areas. The objectives of the study were1. To evaluate the effectiveness of placental blood drainage via umbilical cord in reducing duration and blood loss in third stage of labour. 2. Reducing the incidence of postpartum haemorrhage. 3. Decreasing the complications in third stage of labour and reduce maternal mortality. MATERIALS AND METHODS This study was carried out in 100 full term pregnant women admitted in the labour room in Gauhati medical college and hospital in the department of obstetrics and gynaecology since 1st August 2007 to 30th August 2008. Cases were divided into two. Study group and control group. RESULTS In control group the average duration of third stage was 7.41 minutes and in study group 5.57 minutes and p value was <0.001 which is very highly significant. The blood loss in third stage of labour was more in case of control group, the mean blood loss in control was 169.48 ml and study group was 110.38 ml after delivery of placenta. The post-partum haemorrhage was present in 2% of cases in control group while in study group it was present in 0% case. CONCLUSION Placental blood drainage is one of the additional components in active management of third stage of labour, which is safe, simple and non-invasive method. It reduces the duration of third stage of labour, amount of blood loss and decreases the duration of placental separation time.

    To evaluate the efficacy of xylitol-sweetened milk as a caries-preventive strategy. In this nine-month prospective proof-of-principle trial, Peruvian schoolchildren were randomized to one of five different milk groups: (1) eight g of xylitol per 200 mL milk once per day; (2) four g of xylitol per 100 mL milk twice per day; (3) eight g of sorbitol per 200 mL milk once per day; (4) four g of sorbitol per 100 mL milk twice per day; or (5) eight g of sucrose per 200 mL milk once per day. The primary outcome was plaque mutans streptococci (MS) at nine months. A secondary outcome was caries incidence. We hypothesized that children in the xylitol groups would have a greater MS decline and lower caries incidence. One hundred fifty-three children were randomized in the intent-to-treat analyses. Children receiving xylitol had a greater decline in MS than children receiving sucrose (P=0.02) but were not different from children receiving sorbitol (P=0.07). Dental caries incidence for xylitol once per day or twice per day was 5.3±3.4 and 4.3±4.0 surfaces, respectively, compared to sorbitol once per day, sorbitol twice per day, or sucrose (4.1±2.8, 3.7±4.2, and 3.2±3.4 surfaces, respectively). There were no differences in caries incidence between xylitol and sucrose (rate ratio [RR] = 1.51; 95 percent confidence interval [CI] = 0.88, 2.59; P=0.13) or between xylitol and sorbitol (RR = 1.28; 95 percent CI = 0.90, 1.83; P=0.16). Xylitol-sweetened milk significantly reduced mutans streptococci levels compared to sucrose-sweetened milk, but differences in caries incidence were not detected.

    The incidental detection of small lung nodules in children is a vexing consequence of an increased reliance on CT. We present an algorithm for the management of lung nodules detected on CT in children, based on the presence or absence of symptoms, the presence or absence of elements in the clinical history that might explain these nodules, and the imaging characteristics of the nodules (such as attenuation measurements within the nodule). We provide suggestions on how to perform a thoughtfully directed and focused search for clinically occult extrathoracic disease processes (including malignant disease) that may present as an incidentally detected lung nodule on CT. This algorithm emphasizes that because of the lack of definitive information on the natural history of small solid nodules that are truly detected incidentally, their clinical management is highly dependent on the caregivers' individual risk tolerance. In addition, we present strategies to reduce the prevalence of these incidental findings, by preventing unnecessary chest CT scans or inadvertent inclusion of portions of the lungs in scans of adjacent body parts. Application of these guidelines provides pediatric radiologists with an important opportunity to practice patient-centered and evidence-based medicine. (orig.)

    The American College of Physicians (ACP) developed this guideline to present the evidence and provide clinical recommendations based on the comparative effectiveness of risk assessment scales and preventive interventions for pressure ulcers. This guideline is based on published literature on this topic that was identified by using MEDLINE (1946 through February 2014), CINAHL (1998 through February 2014), the Cochrane Library, clinical trials registries, and reference lists. Searches were limited to English-language publications. The outcomes evaluated for this guideline include pressure ulcer incidence and severity, resource use, diagnostic accuracy, measures of risk, and harms. This guideline grades the quality of evidence and strength of recommendations by using ACP's clinical practice guidelines grading system. The target audience for this guideline includes all clinicians, and the target patient population is patients at risk for pressure ulcers. ACP recommends that clinicians should perform a risk assessment to identify patients who are at risk of developing pressure ulcers. (Grade: weak recommendation, low-quality evidence). ACP recommends that clinicians should choose advanced static mattresses or advanced static overlays in patients who are at an increased risk of developing pressure ulcers. (Grade: strong recommendation, moderate-quality evidence). ACP recommends against using alternating-air mattresses or alternating-air overlays in patients who are at an increased risk of developing pressure ulcers. (Grade: weak recommendation, moderate-quality evidence).

  12. Delirium and high fever are associated with subacute motor deterioration in Parkinson disease: a nested case-control study.

    Directory of Open Access Journals (Sweden)

    Atsushi Umemura

    Full Text Available BACKGROUND: In Parkinson disease (PD, systemic inflammation caused by respiratory infections such as pneumonia frequently occurs, often resulting in delirium in the advanced stages of this disease. Delirium can lead to cognitive and functional decline, institutionalization, and mortality, especially in the elderly. Inflammation causes rapid worsening of PD motor symptoms and signs, sometimes irreversibly in some, but not all, patients. PURPOSE: To identify factors associated with subacute motor deterioration in PD patients with systemic inflammation. METHODS: The association of clinical factors with subacute motor deterioration was analyzed by a case-control study. Subacute motor deterioration was defined as sustained worsening by one or more modified Hoehn and Yahr (H-Y stages. Using multivariable logistic regression incorporating baseline characteristics (age, sex, PD duration, modified H-Y stage, dementia, and psychosis history and statistically selected possible predictors (peak body temperature, duration of leukocytosis, and presence of delirium, the odds ratios for these factors were estimated as relative risks. RESULTS: Of 80 PD patients with systemic inflammation, 26 with associated subacute motor deterioration were designated as cases and the remainder as controls. In the 26 cases, 6 months after its onset the motor deterioration had persisted in 19 patients and resolved in four (three were lost for follow-up. Multivariable logistic regression analysis showed that delirium and body temperature are significantly associated with motor deterioration after systemic inflammation (P = 0.001 for delirium and P = 0.026 for body temperature, the adjusted odds ratios being 15.89 (95% confidence interval [CI]: 3.23-78.14 and 2.78 (95% CI: 1.13-6.83, respectively. CONCLUSIONS: In patients with PD and systemic inflammation, delirium and high body temperature are strong risk factors for subsequent subacute motor deterioration and such deterioration

    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.

    Full Text Available Purpose: To provide resource-stratified, evidence-based recommendations on the secondary prevention of cervical cancer globally. Methods: ASCO convened a multidisciplinary, multinational panel of oncology, primary care, epidemiology, health economic, cancer control, public health, and patient advocacy experts to produce recommendations reflecting four resource-tiered settings. A review of existing guidelines, a formal consensus-based process, and a modified ADAPTE process to adapt existing guidelines were conducted. Other experts participated in formal consensus. Results: Seven existing guidelines were identified and reviewed, and adapted recommendations form the evidence base. Four systematic reviews plus cost-effectiveness analyses provided indirect evidence to inform consensus, which resulted in ≥ 75% agreement. Recommendations: Human papillomavirus (HPV DNA testing is recommended in all resource settings; visual inspection with acetic acid may be used in basic settings. Recommended age ranges and frequencies by setting are as follows: maximal: ages 25 to 65, every 5 years; enhanced: ages 30 to 65, if two consecutive negative tests at 5-year intervals, then every 10 years; limited: ages 30 to 49, every 10 years; and basic: ages 30 to 49, one to three times per lifetime. For basic settings, visual assessment is recommended as triage; in other settings, genotyping and/or cytology are recommended. For basic settings, treatment is recommended if abnormal triage results are present; in other settings, colposcopy is recommended for abnormal triage results. For basic settings, treatment options are cryotherapy or loop electrosurgical excision procedure; for other settings, loop electrosurgical excision procedure (or ablation is recommended.

    2013-01-01

    Abstract Objective: Photodynamic therapy (PDT) as a medical treatment for cancers is an increasing practice in clinical settings, as new photosensitizing chemicals and light source technologies are developed and applied. PDT involves dosing patients with photosensitizing drugs, and then exposing them to light using a directed energy device in order to manifest a therapeutic effect. Healthcare professionals providing PDT should be aware of potential occupational health and safety hazards posed by these treatment devices and photosensitizing agents administered to patients. Materials and methods: Here we outline and identify pertinent health and safety considerations to be taken by healthcare staff during PDT procedures. Results: Physical hazards (for example, non-ionizing radiation generated by the light-emitting device, with potential for skin and eye exposure) and chemical hazards (including the photosensitizing agents administered to patients that have the potential for exposure via skin, subcutaneous, ingestion, or inhalation routes) must be considered for safe use of PDT by the healthcare professional. Conclusions: Engineering, administrative, and personal protective equipment controls are recommendations for the safe use and handling of PDT agents and light-emitting technologies. PMID:23859750

    Suicide behaviour in psychosis is a significant clinical and social problem. There is a dearth of evidence for psychological interventions designed to reduce suicide risk in this population. To evaluate a novel, manualised, cognitive behavioural treatment protocol (CBSPp) based upon an empirically validated theoretical model. A randomly controlled trial with independent and masked allocated and assessment of CBSPp with TAU (n=25, 24 sessions) compared to TAU alone (n=24) using standardised assessments. Measures of suicide probability, and suicidal ideation were the primary outcomes and measures of hopelessness, depression, psychotic symptoms, functioning, and self-esteem were the secondary outcomes, assessed at 4 and 6 months follow-up. The CBSPp group improved differentially to the TAU group on two out of three primary outcome measures of suicidal ideation and suicide probability, and on secondary outcomes of hopelessness related to suicide probability, depression, some psychotic symptoms and self-esteem. CBSPp is a feasible intervention which has the potential to reduce proxy measures of suicide in psychotic patients. Copyright © 2014 Elsevier B.V. All rights reserved.

    Cardiovascular benefits using the 23-valent pneumococcal polysaccharide vaccine (PPV23) are controversial. This study assessed clinical effectiveness of PPV23 in preventing acute myocardial infarction in people over 60-years. We conducted a population-based cohort study involving 27,204 individuals ≥60 years-old in Tarragona, Spain, who were prospectively followed from 01/12/2008 until 30/11/2011. Outcomes were hospitalization for AMI, 30-day mortality from AMI and all-cause death. Cox regression was used to evaluate the association between pneumococcal vaccination and the risk of each outcome. Cohort members were followed for a total of 76,033 person-years, of which 29,065 were for vaccinated subjects. Overall, 359 cases of AMI, 55 deaths from AMI and 2465 all-cause deaths were observed. Pneumococcal vaccination did not alter the risk of AMI (multivariable hazard ratio [HR]: 0.95; 95% confidence interval [CI]: 0.76-1.18; p=0.630), death from AMI (HR: 1.32; 95% CI: 0.76-2.28; p=0.321) and all-cause death (HR: 0.97; 95% CI: 0.89-1.05; p=0.448). In analyses focused on people with and without history of prior coronary artery disease, pneumococcal vaccination did not emerge effective in preventing any analyzed event. This study supports that PPV23 does not provide any relevant benefit against AMI in the general population over 60 years, as in primary as well as in secondary prevention, although it is underpowered to exclude a small benefit of vaccination against rare outcomes.

    Objectives: The aim of this study is to review the available literature on the efficacy and safety of agents used for prevention of RAS. Background: Different vasodilator agents have been used to prevent radial artery spasm (RAS) in patients undergoing transradial cardiac catheterization. Methods: We included studies that evaluated any intra-arterial drug administered in the setting cardiac catheterization that was undertaken through the transradial access site (TRA). We also compared studies for secondary outcomes of major bleeding, procedure time, and procedure failure rate in setting of RAS prevention, patent hemostasis and radial artery occlusion. Results: 22 clinical studies met the inclusion criteria. For placebo, RAS rate was 12% (4 studies, 638 participants), which was similar to 2.5 mg of verapamil 12% (3 studies, 768 participants) but greater than 5 mg of verapamil (4%, 2 studies, 497 participants). For nicorandil, there was a much higher RAS rate compared to placebo (16%, 3 studies, 447 participants). The lowest rates of RAS was found for nitroglycerin at both 100 μg (4%) and 200 μg (2%) doses, isosorbide mononitrate (4%) and nicardipine (3%). We found no information regarding the procedure failure rates, patent hemostasis, and radial artery occlusion in these studies. Conclusions: In this largest and up-to-date review on intra-arterial vasodilators use to reduce RAS, we have found that the verapamil at a dose of 5 mg or verapamil in combination with nitroglycerine are the best combinations to reduce RAS. - Highlights: • Radial artery spasm (RAS) causes procedural failure in transradial catheterization. • RAS may complicate 10–15% procedures undertaken through the radial approach. • We reviewed the efficacy of vasodilators that have been used to minimize RAS. • The pooled RAS rate was lowest with 5 mg of verapamil (4%) compared to placebo (12%). • The best combination of drugs to minimize RAS is nitroglycerine and verapamil.

    This review evaluates costs and benefits associated with acquiring, implementing, and operating clinical decision support systems (CDSSs) to prevent cardiovascular disease (CVD). Methods developed for the Community Guide were used to review CDSS literature covering the period from January 1976 to October 2015. Twenty-one studies were identified for inclusion. It was difficult to draw a meaningful estimate for the cost of acquiring and operating CDSSs to prevent CVD from the available studies ( n  = 12) due to considerable heterogeneity. Several studies ( n  = 11) indicated that health care costs were averted by using CDSSs but many were partial assessments that did not consider all components of health care. Four cost-benefit studies reached conflicting conclusions about the net benefit of CDSSs based on incomplete assessments of costs and benefits. Three cost-utility studies indicated inconsistent conclusions regarding cost-effectiveness based on a conservative $50,000 threshold. Intervention costs were not negligible, but specific estimates were not derived because of the heterogeneity of implementation and reporting metrics. Expected economic benefits from averted health care cost could not be determined with confidence because many studies did not fully account for all components of health care. We were unable to conclude whether CDSSs for CVD prevention is either cost-beneficial or cost-effective. Several evidence gaps are identified, most prominently a lack of information about major drivers of cost and benefit, a lack of standard metrics for the cost of CDSSs, and not allowing for useful life of a CDSS that generally extends beyond one accounting period.

    Early childhood caries, a serious health problem among young children, can be prevented with effective intervention. The aim of this study was to evaluate the efficacy of oral health education and a fluoride varnish in the prevention of caries in children under the age of 3 years. For this single-blind randomized parallel group 1-year clinical trial in Shiraz, 300 children aged 12-24 months with sound primary teeth were selected and randomly divided into three groups (n = 100): (1) control: no preventive intervention; (2) oral health counseling, and (3) oral health counseling and fluoride varnish at baseline and 6 months later. At baseline and 4, 8 and 12 months after the intervention, caries risk reduction was recorded as the primary outcome. The mothers' knowledge and performance regarding oral health in children was used as a secondary outcome. A total of 260 children (mean age: 20.49 ± 7.33 months) completed the study. Compared to group 1, caries risk reduction in group 2 was 28% (95% CI: -39.05 to -17.45) and 31% in group 3 (95% CI: -41.88 to -21.73). However, there was no significant difference between groups 2 and 3 (95% CI: -8.58 to 1.47). In all groups, mothers' knowledge and performance at baseline were low; however, they increased significantly in follow-up appointments in groups 2 and 3 (p Oral health education increased mothers' knowledge and performance regarding oral health in children. Oral health counseling alone or associated with the use of fluoride varnish reduced the caries incidence in young children. © 2016 S. Karger AG, Basel.

    Secondary pharmaceutical measures are effective in all age groups for the prevention of osteoporotic fractures. This prospective study determines the demographics of 566 consecutive osteoporotic hip fractures presenting to a Level 1 Trauma Center. We examine the efficacy of simple treatment recommendations for pharmaceutical treatment of osteoporosis and the factors determining general practitioner and patient compliance with these recommendations in a community setting. One out of four patients (24.5%) had sustained a previous fragility fracture. Mean age was 80 years. Twenty five percent were resident in a nursing home and only 10% were taking anti-resorptive therapy preoperatively. In hospital mortality was 6%, and 39% of recruited patients were dead at 12 months. By this time more than half the survivors were resident in a nursing home. The compliance with anti-resorptive therapy had increased to over 70% consequent to our simple recommendations. Significant differences in GP and patient compliance were observed between nursing home and own residence dwellers. This study demonstrates the efficacy of a simple clinical practice intervention in increasing patient and GP compliance with secondary fracture prevention measures. We also discuss many of the confounding issues determining this compliance.

    Full Text Available Omega-3 polyunsaturated fatty acids (n-3 PUFAs are believed to be important for cardiovascular health. Many investigations have been carried out in an attempt to examine the effect of n-3 PUFAs intake, in the form of supplementation or fortified foods, for the management of cardiovascular disease (CVD and risk factors for CVD, whereas less is known about the effect on healthy individuals. The present study reviews the available literature in order to examine the relationship between n-3 PUFAs intake, either via supplementation or enriched food, and the prevention of CVD among healthy adults. Interventional clinical trials on subjects aged >18 years old with none of the established risk factors for CVD have been considered for review. n-3 PUFAs supplementation or enriched food may positively regulate triglycerides and some lipoprotein subsets, as well as several vascular and coagulation parameters, even in healthy patients, presenting no risk factors for CVD, suggesting a protective effect. Diet enrichment with omega-3 is likely to be useful in helping to lower the risk of developing CVD in healthy individuals, but still offers no strong evidence of a tangible benefit on a population level. Additional studies are needed to determine the optimal daily intake, especially to prevent the unfavorable effects of PUFAs over-consumption.

    Plant-derived elements used for pharmacological applications constitute an increasing research field. Centella asiatica is widely used mainly as an extract (TECA). Triterpenic fractions, the primary constituents of Centella asiatica, produce a wide range of preventive and therapeutic effects. The modulation of collagen production and deposition in wound healing is of primary importance. TECA is also used to treat several microcirculatory problems, inflammatory skin conditions (leprosy, lupus, varicose ulcers, eczema, atopic dermatitis, psoriasis) and also intestinal problems, fever, amenorrhea and genitourinary conditions. Cognitive functions, anxiety and mental impairment may be also affected by TECA administration. New applications in neurology include nerve growth factor enhancement and applications in neurological degenerative conditions. Interaction with other products is also indicated in this document. The multiplicity of actions of TECA is associated to six important mechanisms, all inter-connected and modulating each other: 1) edema - and capillary filtration - control; 2) a strong antioxidant power, effective on several forms of oxidative stress associated to inflammation or infections and synergic with other antioxidant products; 3) an anti-inflammatory action; 4) a modulation of the collagen production avoiding slower scarring or faster, hyperthrophic scarring and cheloids; 5) a modulating action of local growth factors; 6) a modulation of angiogenesis. This "status" paper - resulting from an expert meeting held in Cobham, Surrey, indicates most of the therapeutic potential of TECA, still to be explored in further studies. The status paper constitutes the basis for a consensus document on TECA to be developed in the next future. This "status" paper opens a new window on an ancient but still partially unexplored product that may become an important value in prevention and treatment of several pre-clinical and risk conditions and in clinically significant

    Cervical cancer is the third most common gynecological malignancy in Saudi women with an estimated incidence rate of 1.9 cases per 100 000 women-years. More than 40% of cervical cancer cases are diagnosed at advanced stages due to lack of a routine screening program in Saudi Arabia. Thus, national guidelines for routine screening and treatment of precancerous cervical lesions are needed. The Saudi Centre for Evidence-Based Healthcare invited a panel of local experts and partnered them with a team from McMaster University in Canada for methodological support, to develop national clinical practice guidelines on the screening and treatment of precancerous lesions for cervical cancer. After the panel identified key clinical questions, the McMaster University working group updated existing systematic reviews that had been used for the 2013 WHO Guidelines for screening and treatment of precancerous lesions for cervical cancer prevention. Recommendations were based on the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach. Those recommendations took into account the available evidence, patient values and preferences, and resource use in the Saudi context. The panel provided recommendations on two major issues: screening for precancerous lesions (cervical intraepithelial neoplasia 2 & 3) and treatment of those lesions to prevent cervical cancer in women who tested positive after screening. The Saudi expert panel recommends using the HPV DNA test followed by colposcopy or cytology (Pap test) followed by colposcopy to screen for CIN2+ in women at risk of cervical cancer. The panel recommends cryotherapy or loop excision electrosurgery procedure (LEEP) over cold knife cone biopsy to treat women at risk of cervical cancer that tests positive for CIN2+. Universal screening for precancerous cervical dysplasia in women in Saudi Arabia is recommended using HPV testing and or cytology. Either cryotherapy or LEEP are preferred for treatment. National

    Children with sickle cell anemia (SCA) and conditional transcranial Doppler (TCD) ultrasound velocities (170-199 cm/sec) may develop stroke. However, with limited available clinical data, the current standard of care for conditional TCD velocities is observation. The efficacy of hydroxyurea in preventing conversion from conditional to abnormal TCD (≥200 cm/sec), which confers a higher stroke risk, has not been studied prospectively in a randomized trial. Sparing Conversion to Abnormal TCD Elevation (SCATE #NCT01531387) was an NHLBI-funded Phase III multicenter international clinical trial comparing alternative therapy (hydroxyurea) to standard care (observation) to prevent conversion from conditional to abnormal TCD velocity in children with SCA. SCATE enrolled 38 children from the United States, Jamaica, and Brazil [HbSS (36), HbSβ0-thalassemia (1), and HbSD (1), median age 5.4 years (range, 2.7-9.8)]. Due to slow patient accrual and administrative delays, SCATE was terminated early. In an intention-to-treat analysis, the cumulative incidence of abnormal conversion was 9% (95% CI 0 to 35%) in the hydroxyurea arm and 47% (95% CI 6 to 81%) in observation arm at 15 months (p=0.16). In post-hoc analysis according to treatment received, significantly fewer children on hydroxyurea converted to abnormal TCD velocities, compared to observation (0% versus 50%, p=0.02). After a mean of 10.1 months, a significant change in mean TCD velocity was observed with hydroxyurea treatment (−15.5 versus +10.2 cm/sec, p=0.02). No stroke events occurred in either arm. Hydroxyurea reduces TCD velocities in children with SCA and conditional velocities. PMID:26414435

    Full Text Available Pneumocephalus can develop immediately following head trauma or clinical presentation may be delayed for days. We report a case of 35 year male whose initial CT scan brain plain small specks of pneumocephalus in left para-sellar region. However the next day he was complaining of severe headache and had multiple episodes of vomiting. Repeat CT scan showed increase in the size of pneumocephalus including appearance of intraventricular air with mild cerebral edema. The patient recovered well with conservative management. The present case is a gentle reminder that in a subgroup of head injury patients, intracranial air can produce significant mass effect leading to tension pneumocephalus which can can behave like other intracranial mass lesions and causes worsening of the neurological status of these patients.

    British Columbia falls short in uptake of recommended clinical prevention services, with even lower rates among immigrant populations. This study explored facilitators of and barriers to uptake of clinical prevention services among people from South Asia, who represent 31% of the population in Surrey, British Columbia. We used a qualitative descriptive approach and employed vignettes in a focus group setting to elicit perspectives of South Asian people on accessing clinical prevention services. Participants aged 40 years or more were recruited between October 2014 and February 2015 from health care and community settings such as older-adult housing, day programs and health education events. Letters of introduction to the study were provided in English or Punjabi or both to all potential participants. We conducted qualitative content analysis of the results. Sixty-two South Asian adults (36 women and 26 men) aged 40-87 years participated in 1 of 8 focus groups in health care or community settings. Facilitators of and barriers to accessing clinical prevention services were noted at the patient, primary care provider and health care system levels. Facilitators at the patient level included taking ownership over one's health, health literacy and respecting the provider's advice; barriers included fear of the diagnosis, death and/or procedures, perceived low risk of disease or utility of the intervention, and side effects of procedures. Provider factors centred on a trust-based patient-provider relationship, strong communication and adequate time during visits. Health care system factors included such facilitators as processes to routinely offer prevention services as part of other health care or social services, systems that encourage prevention-oriented family practice and services at low or no cost to the patient. Our findings validate previously identified facilitators of and barriers to accessing preventive care for immigrant populations. However, the results

    Subarachnoid hemorrhage (SAH) results in significant morbidity and mortality, even among patients who reach medical attention in good neurological condition. Many patients have neurological decline in the perioperative period, which contributes to long-term outcomes. The focus of this study is to characterize the incidence of, characteristics predictive of, and outcomes associated with acute postoperative neurological deterioration in patients undergoing surgery for ruptured intracranial aneurysm. The Intraoperative Hypothermia for Aneurysm Surgery Trial (IHAST) was a multicenter randomized clinical trial that enrolled 1001 patients and assesssed the efficacy of hypothermia as neuroprotection during surgery to secure a ruptured intracranial aneurysm. All patients had a radiographically confirmed SAH, were classified as World Federation of Neurosurgical Societies (WFNS) Grade I-III immediately prior to surgery, and underwent surgery to secure the ruptured aneurysm within 14 days of SAH. Neurological assessment with the National Institutes of Health Stroke Scale (NIHSS) was performed preoperatively, at 24 and 72 hours postoperatively, and at time of discharge. The primary outcome variable was a dichotomized scoring based on an IHAST version of the Glasgow Outcome Scale (GOS) in which a score of 1 represents a good outcome and a score > 1 a poor outcome, as assessed at 90-days' follow-up. Data from IHAST were analyzed for occurrence of a postoperative neurological deterioration. Preoperative and intraoperative variables were assessed for associations with occurrence of postoperative neurological deterioration. Differences in baseline, intraoperative, and postoperative variables and in outcomes between patients with and without postoperative neurological deterioration were compared with Fisher exact tests. The Wilcoxon rank-sum test was used to compare variables reported as means. Multiple logistic regression was used to adjust for covariates associated with occurrence

    Despite increasing awareness of obstetric safety initiatives, maternal mortality and severe maternal morbidity in the United States have continued to increase over the past 20 years. Since results from large-scale surveillance programs suggest that up to 50% of maternal deaths may be preventable, new efforts are focused on developing and testing early warning systems for the obstetric population. Early warning systems are a set of specific clinical signs or symptoms that trigger the awareness of risk and an urgent patient evaluation, with the goal of reducing severe morbidity and mortality through timely diagnosis and treatment. Early warning systems have proven effective at predicting and reducing mortality and severe morbidity in medical, surgical, and critical care patient populations; however, there has been limited research on how to adapt these tools for use in the obstetric population, where physiologic changes of pregnancy render them inadequate. In this article, we review the available obstetric early warning systems and present evidence for their use in reducing maternal mortality and severe maternal morbidity. We also discuss considerations and strategies for implementation and acceptance of these early warning systems for clinical use in obstetrics. Copyright © 2017 Elsevier Inc. All rights reserved.

    To evaluate the clinical results of using end plate rings in preventing subsidence of titanium cage in anterior cervical corpectomy and fusion (ACCF) surgery. The clinical data of 71 patients with cervical spondylotic myelopathy underwent ACCF in single segment from February 2008 to February 2011 were retrospectively analyzed. There were 38 males and 33 females, aged from 39 to 74 years old with a mean of 53.8 years. Thirty-three were used end plate rings and thirty-eight were not used (end plate rings group and no end plate ring group, respectively). The Japanese Orthopaedic Association (JOA) score, Odom's scale, imaging data were used to evaluate the clinical effects. Imaging data including Cobb angle of fusion segment, intervertebral height of anterior border (Da) and posterior border (Dp), the mean intervertebral height (Dm). All patients were followed up from 13 to 34 months with an average of 19.5 months. Between two groups, there was no significant difference in Cobb angle of fusion segment and the mean intervertebral height (Dm) before surgery and one week after surgery. Whereas, one year after surgery, the Cobb angle of end plate ring group was (9.4 ± 3.8) degrees, and contral group was (7.5 ± 3.9) degrees, which was significantly lower than that of end plate ring group. Meanwhile, the Dm of end plate ring group was (57.3 ± 2.2) mm, and no end ring group was (55.2 ± 2.6) mm which was significantly lower than that of end plate ring group. The subsidence in end plate ring group was 57.6%, and was 78.9% in no end plate ring group. There was no significant difference in JOA score before and after surgery between two groups. At 1 year after operation, 90.9% (30/33) got excellent or good results in end plate ring group, 89.5% (33/38) got excellent or good results in contral group. The use of end plate rings could not completely prevent the subsidence of titanium cage, however, which can decrease the occurrence rate of the subsidence and lessen its degree.

    Recent studies suggest that by the middle of this century, as many as 14 million Americans will have Alzheimer's disease, creating an enormous strain on families, the health care system and the federal budget. There are still widespread misconceptions about issues related to the prevention and/or treatment of disease pathogenesis, leaving us unprepared to deal with the disease. To address these challenges, several therapeutic approaches are currently under investigation, mainly in an attempt to delay disease onset and eventually slow down its progression. Recent epidemiological evidence has implicated the protective role of dietary polyphenols from grape products against Alzheimer's disease. Furthermore, experimental evidence supports the hypothesis that certain bioactive grape-derived polyphenols may protect against Alzheimer's disease-type cognitive deterioration, in part by interfering with the generation and assembly of β-amyloid peptides into neurotoxic oligomeric aggregated species. Brain-targeting polyphenols have been shown to significantly reduce the generation of β-amyloid peptides in primary cortico-hippocampal neuron cultures, and preliminary results indicate that they may influence neuronal synaptic plasticity. Recent evidence has also implicated the role of certain grape-derived preparations in beneficially modulating tau neuropathology, including reducing tau aggregation. Studies suggest that dietary polyphenolics may benefit Alzheimer's disease by modulating multiple disease-modifying modalities, both β-amyloid-dependent and independent mechanisms, and provide impetus for the development of polyphenolic compounds for Alzheimer's disease prevention and/or therapy.

    Importance Preventing early pregnancy among vulnerable adolescents requires innovative and sustained approaches. Prime Time, a youth development intervention, aims to reduce pregnancy risk among adolescent girls seeking clinic services who are at high risk for pregnancy. Objective To evaluate sexual risk behaviors and related outcomes with a 24-month postbaseline survey, 6 months after the conclusion of the Prime Time intervention. Design Randomized controlled trial. Setting Community and school-based primary care clinics. Participants Of 253 sexually active 13- to 17-year-old girls meeting specified risk criteria, 236 (93.3%) completed the 24-month follow-up survey. Intervention Offered during an 18-month period, Prime Time includes case management and youth leadership programs. Main Outcome Measures Self-reported consistency of condom, hormonal, and dual-method contraceptive use with most recent male sex partner and number of male sex partners in the past 6 months. Results At 24-month follow-up, the intervention group reported significantly more consistent use of condoms, hormonal contraception, and dual-method contraception than the control group. Intervention participants also reported improvements in family connectedness and self-efficacy to refuse unwanted sex, and reductions in the perceived importance of having sex. No between-group differences were found in the number of recent male sex partners. Conclusions and Relevance This study contributes to what has been a dearth of evidence regarding youth development interventions offered through clinic settings, where access to high-risk adolescents is plentiful but few efforts have emphasized a dual approach of strengthening sexual and nonsexual protective factors while addressing risk. Findings suggest that health services grounded in a youth development framework can lead to long-term reductions in sexual risk among vulnerable youth. PMID:23440337

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

    Seeking treatment in a timely manner may prevent lower limb amputation subsequent to diabetic foot ulcers. Knowledge regarding the warning signs is one important factor that is related to the timely treatment seeking of patients with diabetic foot ulcers. However, there is no previous research on which aspects of such knowledge that patients with diabetes are lacking. The aims of this study were to test the psychometric properties of a questionnaire that was designed to assess the knowledge of the warning signs of diabetic foot ulcer deterioration and to determine the knowledge of these warning signs among patients with a history of diabetic foot ulcers. A cross-sectional study design was used. Patients with a history of diabetic foot ulcers were recruited using convenience sampling (N = 385). Data were analyzed using Spearman's rank correlation and the Mann-Whitney U test. The questionnaire showed good known-group validity, satisfied internal consistency (Kuder-Richardson Formula 20 = .82), and exhibited acceptable 2-week test-retest reliability (Spearman's rho coefficient = .75). More than 30% of the participants were unaware of the warning signs of peripheral vascular insufficiency and severe infection. Of the participants, 75.8% felt that the time to seek medical treatment of diabetic foot ulcers was when they experienced wound deterioration. Those who held this opinion had significantly less knowledge regarding the warning signs of diabetic foot ulcer deterioration than did those who had not. Other factors that were significantly associated with less knowledge included being older, having less education, not having an existing foot ulcer, having no foot ulcer treatment history, and never having received education regarding foot ulcers. The questionnaire showed adequate validity and reliability and thus may be used by healthcare practitioners and researchers to assess the knowledge of at-risk patients regarding the warning signs of diabetic foot ulcer

    Full Text Available Urinary tract infections (UTIs are common and result in an enormous economic burden. The increasing prevalence of antibiotic-resistant microorganisms has stimulated interest in non-antibiotic agents to prevent UTIs.To evaluate the cost-effectiveness of cranberry prophylaxis compared to antibiotic prophylaxis with trimethoprim-sulfamethoxazole (TMP-SMX over a 12 month period in premenopausal women with recurrent UTIs.An economic evaluation was performed alongside a randomized trial. Primary outcome was the number of UTIs during 12 months. Secondary outcomes included satisfaction and quality of life. Healthcare utilization was measured using questionnaires. Missing data were imputed using multiple imputation. Bootstrapping was used to evaluate the cost-effectiveness of the treatments.Cranberry prophylaxis was less effective than TMP-SMX prophylaxis, but the differences in clinical outcomes were not statistically significant. Costs after 12 months in the cranberry group were statistically significantly higher than in the TMP-SMX group (mean difference €249, 95% confidence interval 70 to 516. Cost-effectiveness planes and cost-effectiveness acceptability curves showed that cranberry prophylaxis to prevent UTIs is less effective and more expensive than (dominated by TMP-SMX prophylaxis.In premenopausal women with recurrent UTIs, cranberry prophylaxis is not cost-effective compared to TMP-SMX prophylaxis. However, it was not possible to take into account costs attributed to increased antibiotic resistance within the framework of this randomized trial; modeling studies are recommended to investigate these costs. Moreover, although we based the dosage of cranberry extract on available evidence, this may not be the optimal dosage. Results may change when this optimal dosage is identified.ISRCTN.org ISRCTN50717094.

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

    Full Text Available Background: Contrast induced nephropathy is a potential cause of mortality and morbidity in patients undergoing angiography–angioplasty. Except for hydrating and probably low – isoosmolar contrast agents in high risk groups, other modalities have not provided benefit. We investigated preventive effects of captopril for contrast induced nephropathy during angiography–angioplasty. Methods: In a double blind placebo controlled clinical trial, 88 patients were randomized to two groups: 42 patients received captopril (12.5 mg every 8 hours from 2 hours before the procedure until 48 hours thereafter, and 46 patients received placebo in the same manner. Serum creatinine was measured before and 48 hours after angioplasty. The data were analyzed by SPSS software, using unpaired student t-test for comparing mean creatinine rise in both groups and paired student t-test for the changes in serum creatinine in each group. Results: The mean creatinine rise in captopril group (0.214 mg/dl and placebo group (0.226 mg/dl were not significantly different. The incidence of acute renal failure (creatinine rise more than 0.5 mg/dl in the captopril (11.9 % and placebo group (10.8 % were not significantly different. Conclusion: Captopril does not effectively prevent contrast nephropathy, but it is not harmful for renal function and can be administered safely during angiography – angioplasty in patients with normal renal function. However, the effect of captopril in patients with high- risk characteristics remains to be clarified. Of note, we found a trend for less creatinine rise in diabetics who received captopril during the procedure in comparison to diabetics who received placebo.

    Preventing scar contracture after burn injury is a critical goal during recovery. Although the need for intervention is well-understood, data on specific techniques are limited. The study's objective is to provide data for the use of a foam abduction wedge in terms of safety, effectiveness, and patient and caregiver satisfaction through a prospective, single-arm trial. All patients presenting with a burn injury that required grafting in the axillary region and placed them at risk for shoulder joint contracture were offered inclusion. Patient outcomes were recorded for the duration of their burn intensive care unit admission. Ten subjects completed the protocol with a mean duration of wedge use of 41.5 ± 32.5 days. At discharge, the mean shoulder abduction was 132° ± 38° on the left and 118° ± 22° on the right. The mean shoulder flexion was 132° ± 31° on the left and 123° ± 29° on the right. As much as 90% of the subjects had greater than 90° of shoulder abduction and flexion at discharge. There were no observations of worsening burn injury wounds, graft failure, or new pressure-related wounds. One patient was found to have an upper-extremity peripheral nerve injury that was not clearly associated with the splint. Patient and nursing surveys indicated areas of satisfaction as well as areas for potential improvement. This study illustrates the anticipated clinical outcomes and care issues associated with the use of a specific contracture prevention method used in the burn intensive care unit setting as well as identifying areas for future research.

    Nearly 30% of the obese patients treated with hypoenergetic diets for weight reduction develop gallstone disease (GD). Until the present time, the use of ursodeoxycholic acid (UDA) is the only available therapeutic measure to avoid the development of GD. Dietary fiber induce a bile acid synthesis. A double-blind clinical trial was conducted to compare the effect of rational diet plus UDA vs a rational diet supplemented with Psyllium plantago (Pp) for the prevention of GD in obese subjects undergoing a weight-reduction diet. Patients with a body mass index (BMI = weight in Kg/square height in m) of 30 Kg/m2 or more and with normal gallbladder and biliary tree ultrasound (GBUS) were included. Weight-reduction diets were individually calculated for each patient according to their energy expenditure (EE). Patients were randomly and blindly assigned either to group I (diet + 750 mg UDA + fiber placebo) or group II (diet + 15 g Pp+ UDA placebo). An anthropometric evaluation was performed to each patient before and after the two-month treatment, as well as resting EE by indirect calorimetry, GBUS and endoscopy for the determination of cholesterol crystals in duodenal bile. Weight reduction was similar in both groups (group I = 6 +/- 2 Kg vs group II = 6 +/- 3 Kg). GD development was observed in one patient of group I (5.5%) and two patients of group II (p > 0.05). All patients with GD lost a minimum of 4 Kg during the study period. GD development did not correlate with the presence of crystals in the duodenal bile at the beginning of the study. Our results suggest a beneficial effect of a rational diet with fiber supplementation to prevent GD development in obese patients included in a weight reduction program.

    To evaluate the efficacy and safety of auto-crosslinked hyaluronic acid (HA) gel for preventing intrauterine adhesion (IUA) after hysteroscopic adhesiolysis. A prospective, randomized, double blinded and controlled clinical trial (level I) was performed. According to American Fertility Society (AFS) scoring system, 120 patients (treatment group: 60 cases, control group: 60 cases) with moderate to severe IUA were enrolled. Upon completion of adhesiolysis, a Foley balloon catheter was first introduced into the uterine cavity and then 3 ml of auto-crosslinked HA gel for patients in the treatment group; patients in the control group, however, only received Foley balloon catheter. Second-look hysteroscopic examination was performed to all patients at 3 months postoperatively for evaluation of IUA. Primary endpoint was the reduction rate of IUA at 3 months after surgery. The secondary endpoints include total AFS score, score of each individual AFS category. At 3 months after surgery, auto-crosslinked HA gel resulted in significantly higher effective rate for reduction of adhesion, the effective rate were 76% (42/55) and 48% (27/56) respectively (P = 0.000 9); the total AFS score of treatment group was 2.1 ± 1.1, and significantly lower than that of control group (3.7 ± 2.5, P = 0.000 8). Application of auto-crosslinked HA gel after surgery significantly enhanced the improvement for each individual patient with regard to their adhesive type and menstrual pattern (P = 0.037 8, P = 0.000 4). The treatment group had significantly lower proportion of patients with moderate to severe adhesive stages than that of control group [13% (7/55) versus 38% (21/56), P = 0.000 6]. No adverse events and complications were observed. Auto-crosslinked HA gel coule be able to reduce IUA, decrease adhesion severity, and improve menopause postoperatively. This absorbable auto-crosslinked HA gel is proposed as a barrier for preventing IUA after intrauterine procedures.

    The benefits achieved by implementing cardiovascular prevention strategies in terms of reduced incidence of atherosclerotic diseases and mortality are accepted, worldwide. In particular, the clinical management of hypercholesterolemia has a fundamental role for all preventive strategies, both in primary and secondary prevention, at each stage of cardiovascular risk. Since the net clinical benefit of lipid-lowering therapy largely depends on baseline individual cardiovascular risk profile, the assessment of individual risk is essential to establish type and intensity of both preventive and therapeutic strategies. Thus, the real challenge in a setting of clinical practice is not only to identify whom to treat among individuals at low-to-moderate risk, but mostly how much and how long to treat high or very-high risk patients. This manuscript, which reflects concepts and positions that have been published in a more extensive document of the Italian Society for Cardiovascular Prevention (SIPREC), deals with the diagnostic and therapeutic management of patients with dyslipidaemia, with an evidence-based approach adapted and updated from recent guidelines of the European Society of Cardiology and very recent results of randomized clinical trials. The purpose is to suggest a multidimensional and integrated actions aimed at eliminating or minimizing the impact of cardiovascular diseases and their related disabilities and mortality in patients with hypercholesterolemia.

    Full Text Available Optimal pricing and marketing planning plays an essential role in production decisions on deteriorating items. This paper presents a mathematical model for a three-level supply chain, which includes one producer, one distributor and one retailer. The proposed study considers the production of a deteriorating item where demand is influenced by price, marketing expenditure, quality of product and after-sales service expenditures. The proposed model is formulated as a geometric programming with 5 degrees of difficulty and the problem is solved using the recent advances in optimization techniques. The study is supported by several numerical examples and sensitivity analysis is performed to analyze the effects of the changes in different parameters on the optimal solution. The preliminary results indicate that with the change in parameters influencing on demand, inventory holding, inventory deteriorating and set-up costs change and also significantly affect total revenue.

    Full Text Available Marketing strategies and proper inventory replenishment policies are often incorporated by enterprises to stimulate demand and maximize profit. The aim of this paper is to represent an integrated model for dynamic pricing and inventory control of deteriorating items. To reflect the dynamic characteristic of the problem, the selling price is defined as a time-dependent function of the initial selling price and the discount rate. In this regard, the price is exponentially discounted to compensate negative impact of the deterioration. The planning horizon is assumed to be infinite and the deterioration rate is time-dependent. In addition to price, the demand rate is dependent on advertisement as a powerful marketing tool. Several theoretical results and an iterative solution algorithm are developed to provide the optimal solution. Finally, to show validity of the model and illustrate the solution procedure, numerical results are presented.

    Full Text Available How to sell fresh products quickly to decrease the storage cost and to meet customer quality requirement is of vital importance in the food supply chain. Bundling fresh products is an efficient strategy to promote sales and reduce storage pressure of retailers. In this paper, we consider the bundle pricing decisions for homogeneous fresh products with quality deterioration. The value of fresh products with quality deterioration is approximated as an exponential function based on which customer’s reservation prices are calculated. A nonlinear mixed integer programming model is used to formulate the bundle pricing problem for fresh products. By adding auxiliary decision variables, this model is converted into a mixed integer linear program. Numerical experiments and sensitive analysis are conducted to provide managerial insights for bundling fresh products with quality deterioration.

    Patients who deteriorate without recognition or timely interventions are at risk of critical care admission and increased morbidity or mortality. This article outlines the systematic ABCDE (airway, breathing, circulation, disability, exposure) approach to patient assessment, which enables healthcare practitioners to identify and respond to life-threatening conditions in order of priority. The patient's vital signs should be measured as part of the ABCDE assessment and recorded using a track and trigger tool to enhance recognition of physiological abnormalities that signal deterioration. To optimise communication and escalation of deteriorating patients, healthcare practitioners should report ABCDE assessment findings using a structured communication tool. ©2017 RCN Publishing Company Ltd.

    Diabetes prevention is imperative to slow worldwide growth of diabetes-related morbidity and mortality. Yet the long-term efficacy of prevention strategies remains unknown. To estimate aggregate long-term effects of different diabetes prevention strategies on diabetes incidence. Systematic searches of MEDLINE, EMBASE, Cochrane Library, and Web of Science databases. The initial search was conducted on January 14, 2014, and was updated on February 20, 2015. Search terms included prediabetes, primary prevention, and risk reduction. Eligible randomized clinical trials evaluated lifestyle modification (LSM) and medication interventions (>6 months) for diabetes prevention in adults (age ≥18 years) at risk for diabetes, reporting between-group differences in diabetes incidence, published between January 1, 1990, and January 1, 2015. Studies testing alternative therapies and bariatric surgery, as well as those involving participants with gestational diabetes, type 1 or 2 diabetes, and metabolic syndrome, were excluded. Reviewers extracted the number of diabetes cases at the end of active intervention in treatment and control groups. Random-effects meta-analyses were used to obtain pooled relative risks (RRs), and reported incidence rates were used to compute pooled risk differences (RDs). The main outcome was aggregate RRs of diabetes in treatment vs control participants. Treatment subtypes (ie, LSM components, medication classes) were stratified. To estimate sustainability, post-washout and follow-up RRs for medications and LSM interventions, respectively, were examined. Forty-three studies were included and pooled in meta-analysis (49 029 participants; mean [SD] age, 57.3 [8.7] years; 48.0% [n = 23 549] men): 19 tested medications; 19 evaluated LSM, and 5 tested combined medications and LSM. At the end of the active intervention (range, 0.5-6.3 years), LSM was associated with an RR reduction of 39% (RR, 0.61; 95% CI, 0.54-0.68), and medications were associated

    64% and 34%, respectively, compared with the SMA + FC group. We conclude that prophylactic COL-3 prevented the development of ARDS and unexpectedly also prevented septic shock in a chronic insidious onset animal model of sepsis-induced ARDS. The mechanism of this protection is unclear, as COL-3 inhibited numerous inflammatory mediators. Nevertheless, COL-3 significantly reduced the morbidity in a clinically applicable animal model, demonstrating the possibility that COL-3 may be useful in reducing the morbidity associated with sepsis and ischemia/reperfusion injury in patients.

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

    Multiple randomized controlled trials (RCTs) have assessed the effects of supplementation with eicosapentaenoic acid plus docosahexaenoic acid (omega-3 polyunsaturated fatty acids, commonly called fish oils) on the occurrence of clinical cardiovascular diseases. Although the effects of supplementation for the primary prevention of clinical cardiovascular events in the general population have not been examined, RCTs have assessed the role of supplementation in secondary prevention among patients with diabetes mellitus and prediabetes, patients at high risk of cardiovascular disease, and those with prevalent coronary heart disease. In this scientific advisory, we take a clinical approach and focus on common indications for omega-3 polyunsaturated fatty acid supplements related to the prevention of clinical cardiovascular events. We limited the scope of our review to large RCTs of supplementation with major clinical cardiovascular disease end points; meta-analyses were considered secondarily. We discuss the features of available RCTs and provide the rationale for our recommendations. We then use existing American Heart Association criteria to assess the strength of the recommendation and the level of evidence. On the basis of our review of the cumulative evidence from RCTs designed to assess the effect of omega-3 polyunsaturated fatty acid supplementation on clinical cardiovascular events, we update prior recommendations for patients with prevalent coronary heart disease, and we offer recommendations, when data are available, for patients with other clinical indications, including patients with diabetes mellitus and prediabetes and those with high risk of cardiovascular disease, stroke, heart failure, and atrial fibrillation. © 2017 American Heart Association, Inc.

    Full Text Available A continuous production control inventory model for deteriorating items with shortages is developed. A number of structural properties of the inventory system are studied analytically. The formulae for the optimal average system cost, stock level, backlog level and production cycle time are derived when the deterioration rate is very small. Numerical examples are taken to illustrate the procedure of finding the optimal total inventory cost, stock level, backlog level and production cycle time. Sensitivity analysis is carried out to demonstrate the effects of changing parameter values on the optimal solution of the system.

    To develop clinical practice guidelines (CPGs) for prevention, diagnosis, treatment and follow-up of ocular injuries caused by exposure to mustard gas. The clinical questions were designed by the guideline team. Websites and databases including National Guidelines Clearinghouse, National Institute for Clinical Excellence, Cochrane, and PubMed were searched to find related CPGs and explore possible answers to the clinical questions. Since there were no relevant CPGs in the literature, related articles in Persian and English languages were extracted. Each article along with its level of evidence was summarized. Additionally, hand search was performed by looking the reference list of each article. Consequently, recommendations were developed considering the clinical benefits and side effects of each therapeutic modality. The recommendations were re-evaluated in terms of customization criteria. All recommendations along with the related evidence were scored from 1 to 9 by experts from all medical universities of Iran. The level of agreement among the experts was evaluated by analyzing the given scores. The agreement was achieved for all recommendations. The experts suggested a number of minor modifications which were applied to the recommendations. Finally, CPGs were developed with 98 recommendations under three major domains including prevention of injury, diagnosis and management of the acute and delayed-onset mustard gas ocular injuries. Considering the lack of CPGs for the prevention, diagnosis, and management of mustard gas-induced keratitis, these recommendations would be useful to prevent the serious ocular complications of mustard gas and standardize eye care services to the affected individuals.

    The early identification of dengue infection is essential for timely and effective quarantine and vector control measures for preventing outbreaks of the disease. Kaohsiung City is responsible for most of the dengue cases in Taiwan. Thus, this study aims to identify major factors involved in the prevalence of dengue fever by analyzing the epidemiological and clinical characteristics, and to establish associations between weather parameters and dengue occurrence in this City. A retrospective study was conducted with 3,322 confirmed dengue cases. Appropriate statistical methods were used to compare differences and correlations between dengue occurrence and demographic, clinical and weather parameters. The outbreak of dengue fever was found to be initiated by imported cases of dengue viruses from other endemic countries. Most of the confirmed cases were not reported to the health authority during the first visit to a doctor, and it took a median of 5 days after the appearance of the first syndromes for medical personnel to report suspected dengue cases. Accordingly, Aedes mosquitoes would have enough time to be infected and transmit the dengue virus. The diagnosis and notification criteria should not only include common symptoms of fever, myalgia, headache, skin rash and arthralgia, but should also be adjusted to include the most frequent symptoms of loss of appetite and feeling thirsty to shorten the notification time. Significantly positive correlations were found between the number of confirmed cases and weather parameters (i.e., temperature, rainfall and relative humidity) at a time lag of 1 month and 2 months. The predictive models for dengue occurrence using these three parameters at a 2-month lag time were established. The surveillance of imported cases, adjustment of notification criteria and application of climatic predictive models would be helpful in strengthening the dengue early warning surveillance system.

    Hepatic damage during transarterial chemoembolization (TACE) is a critical complication in patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). Apart from its role in preventing HBV reactivation, there is some evidence for the benefits of preemptive antiviral therapy in TACE. This study evaluated the effect of preemptive antiviral therapy on acute hepatic deterioration following TACE. This retrospective observational study included a prospectively collected cohort of 108 patients with HBV-related HCC who underwent TACE between January 2007 and January 2013. Acute hepatic deterioration following TACE was evaluated. Treatment-related hepatic decompensation was defined as newly developed encephalopathy, ascites, variceal bleeding, elevation of the bilirubin level, prolongation of prothrombin time, or elevation of the Child-Pugh score by ≥2 within 2 weeks following TACE. Univariate and multivariate analyses were conducted to identify factors influencing treatment-related decompensation. Preemptive antiviral therapy involves directing prophylaxis only toward high-risk chronic hepatitis B patients in an attempt to prevent the progression of liver disease. We regarded at least 6 months as a significant duration of preemptive antiviral treatment before diagnosis of HCC. Of the 108 patients, 30 (27.8%) patients received preemptive antiviral therapy. Treatment-related decompensation was observed in 25 (23.1%) patients during the follow-up period. Treatment-related decompensation following TACE was observed more frequently in the nonpreemptive group than in the preemptive group (29.5% vs. 6.7%, P =0.008). In the multivariate analysis, higher serum total bilirubin (Hazard ratio [HR] =3.425, P =0.013), hypoalbuminemia (HR=3.990, P =0.015), and absence of antiviral therapy (HR=7.597, P =0.006) were significantly associated with treatment-related hepatic decompensation. Our findings suggest that preemptive antiviral therapy significantly reduces the

    In most of the inventory models in the literature, the deterioration rate of goods is viewed as an exogenous variable, which is not subject to control. In the real market, the retailer can reduce the deterioration rate of product by making effective capital investment in storehouse equipments. In this study, we formulate a deteriorating inventory model with time-varying demand by allowing preservation technology cost as a decision variable in conjunction with replacement policy. The objective is to find the optimal replenishment and preservation technology investment strategies while minimising the total cost over the planning horizon. For any given feasible replenishment scheme, we first prove that the optimal preservation technology investment strategy not only exists but is also unique. Then, a particle swarm optimisation is coded and used to solve the nonlinear programming problem by employing the properties derived from this article. Some numerical examples are used to illustrate the features of the proposed model.

    Community-dwelling veterans at risk for suicide may be in contact with a variety of providers in agency-based settings that offer health and human services. The study aim is to describe the perspective of agency-based clinical and community providers who may come into contact with veterans in need of suicide prevention services and to examine the nature of their personal and professional relationships to individuals at risk for suicide among this sample. This study reports on qualitative data from a sample of Veterans' Affairs (VA) and community providers serving veterans and military families in one Midwestern state ( N = 70). Providers completed a survey assessing exposure to suicide, including contact with and relationship to someone suicidal, and organizational characteristics of the providers' employing agencies. Semi-structured interview questions probed for the nature of how they would react with suicidal individuals. Most providers (94%) had some prior contact with someone who was suicidal, and nearly three quarters (77%) knew someone who had died by suicide. Providers reported powerful emotional responses of sadness and remorse to suicidal experiences. While these providers interact with veterans and military families as part of their jobs, they may have their own history of being exposed to suicide, both professionally and personally.

    Full Text Available Objectives: About two-thirds of cancer patients undergo radiotherapy. Oral mucositis represents a major complication of radiotherapy, causing morbidity and mortality and decreasing the quality of life of patients. This study aimed to assess the preventive effect of Glycyrrhiza aqueous extract on oral mucositis in cancer patients under head and neck radiotherapy.Materials and Methods: In this double-blind clinical trial, 37 head and neck cancer patients were divided into intervention (n=19 group receiving Glycyrrhiza aqueous extract and control (n=18 group receiving placebo. Patients in the test group used Glycyrrhiza aqueous extract topically twice a day from the first day of starting radiotherapy until the end of the second week. Patients were examined in the first day of radiotherapy for any type of wound before treatment and those with oral ulcers before radiotherapy were excluded from the study. The grade of mucositis was determined using the classification by the World Health Organization. ANCOVA was performed to assess any difference between the two groups with regard to oral mucosal irritation and wound size after the intervention while controlling for the covariates such as sex and age.Results: Significant differences were found in the maximum grade of mucositis and oral mucosal irritation between the intervention and control groups (P<0.001.Conclusions: This study showed that aqueous extract of Glycyrrhiza can be effective for decreasing the severity of oral mucositis in head and neck cancer patients undergoing radiotherapy.

    The aim of the present study was to examine the influence of a supervised and regular program of aquatic activities throughout gestation on maternal weight gain and birth weight. A randomized clinical trial. Instituto de Obstetricia, Ginecología y Fertilidad Ghisoni (Buenos Aires, Argentina). One hundred eleven pregnant women were analyzed (31.6 ± 3.8 years). All women had uncomplicated and singleton pregnancies; 49 were allocated to the exercise group (EG) and 62 to the control group (CG). The intervention program consisted of 3 weekly sessions of aerobic and resistance aquatic activities from weeks 10 to 12 until weeks 38 to 39 of gestation. Maternal weight gain, birth weight, and other maternal and fetal outcomes were obtained by hospital records. Student unpaired t test and χ 2 test were used; P values ≤.05 indicated statistical significance. Cohen's d was used to determinate the effect size. There was a higher percentage of women with excessive maternal weight gain in the CG (45.2%; n = 28) than in the EG (24.5%; n = 12; odds ratio = 0.39; 95% confidence interval: 0.17-0.89; P = .02). Birth weight and other pregnancy outcomes showed no differences between groups. Three weekly sessions of water activities throughout pregnancy prevents excessive maternal weight gain and preserves birth weight. The clinicaltrial.gov identifier: NCT 02602106.

    Full Text Available Randomized clinical trials of oral antiretroviral pre-exposure prophylaxis (PrEP for HIV prevention have widely divergent efficacy estimates, ranging from 0% to 75%. These discrepancies are likely due to differences in adherence. To our knowledge, no studies to date have examined the impact of improving adherence through monitoring and/or intervention, which may increase PrEP efficacy, or reported on objective behavioral measures of adherence, which can inform PrEP effectiveness and implementation.Within the Partners PrEP Study (a randomized placebo-controlled trial of oral tenofovir and emtricitabine/tenofovir among HIV-uninfected members of serodiscordant couples in Kenya and Uganda, we collected objective measures of PrEP adherence using unannounced home-based pill counts and electronic pill bottle monitoring. Participants received individual and couples-based adherence counseling at PrEP initiation and throughout the study; counseling was intensified if unannounced pill count adherence fell to 80% adherence. Study limitations include potential shortcomings of the adherence measures and use of a convenience sample within the substudy cohort.The high PrEP adherence achieved in the setting of active adherence monitoring and counseling support was associated with a high degree of protection from HIV acquisition by the HIV-uninfected partner in heterosexual serodiscordant couples. Low PrEP adherence was associated with sexual behavior, alcohol use, younger age, and length of PrEP use. Please see later in the article for the Editors' Summary.

    A prospective, randomized controlled clinical trial was conducted in 33 Italian surgical departments with the aim of evaluating the efficacy of octreotide in the prevention of pancreatic fistula after elective pancreatic resections. Between July 1990 and May 1992, 278 patients were enrolled in the study. Fifty-four dropped out because of unresectable disease and six were excluded because of protocol violation; the remaining 218 were randomly assigned to the octreotide group (n = 111) or to the placebo group (n = 107). There were 131 men and 87 women with a mean age of 58.2 +/- 11.7 yrs. Pancreaticoduodenectomy was the most common operation performed (n = 143), sixty-four percent of patients had a pancreatic or periampullary cancer; chronic pancreatitis accounted for 8.2% of cases. Mortality rate was 6.9%. A pancreatic fistula occurred in 31 patients (14.2%), 9% in the octreotide group and 19.6% in the placebo group (p < 0.05). Morbidity rate was significantly lower in the octreotide (21.6%) than in the placebo group (36.4%) (p < 0.05). When specific pancreatic complications were grouped together and evaluated, they occurred less frequently in the treated (15.3%) than in the placebo group (29.9%) (p < 0.05). Octreotide was able to reduce significantly the incidence of pancreatic fistula after elective pancreatic resections.

    Latent cytomegalovirus (CMV) infection is present in more than half the adult population, and a viral reactivation (ie, when the virus becomes measurable in body fluids such as blood) can occur in up to one-third of these individuals during episodes of critical illness. To determine whether antiviral therapy is safe and effective for preventing CMV reactivation in a general population of critically ill patients. A single-center, open-label, randomized, controlled clinical trial recruited 124 CMV-seropositive patients undergoing mechanical ventilation for at least 24 hours in the intensive care unit between January 1, 2012, and January 31, 2014. The mean baseline Acute Physiology and Chronic Health Evaluation II score of all patients was 17.6. Patients were randomized to receive anti-CMV prophylaxis with valacyclovir hydrochloride (n = 34) or low-dose valganciclovir hydrochloride (n = 46) for up to 28 days to suppress viral reactivation, or to a control group with no intervention (n = 44). Time to first CMV reactivation in blood within the 28-day follow-up period following initiation of the study drug. Among the 124 patients in the study (46 women and 78 men; mean [SD] age, 56.9 [16.9] years), viral reactivation in the blood occurred in 12 patients in the control group, compared with 1 patient in the valganciclovir group and 2 patients in the valacyclovir group (combined treatment groups vs control: hazard ratio, 0.14; 95% CI 0.04-0.50). Although this trial was not powered to assess clinical end points, the valacyclovir arm was halted prematurely because of higher mortality; 14 of 34 patients (41.2%) had died by 28 days, compared with 5 of 37 (13.5%) patients in the control arm at the point of the decision to halt this arm. Other safety end points showed similar outcomes between groups. Antiviral prophylaxis with valacyclovir or low-dose valganciclovir suppresses CMV reactivation in patients with critical illness. However, given the higher mortality, a

    Following the reported success of biofilm applications on metal surfaces to inhibit microbiologically influenced corrosion, effectiveness and sustainability of E. coli DH5α biofilm on mortar surface to prevent microbiologically influenced concrete deterioration (MICD) are investigated. Experiments simulating microbial attack were carried out by exposing incrementally biofilm-covered mortar specimens to sulfuric acid solutions with pH ranging from 3 to 6. Results showed that calcium concentration in control reactors without biofilm was 23–47% higher than the reactors with biofilm-covered mortar. Formation of amorphous silica gel as an indication of early stages of acid attack was observed only on the control mortar specimens without biofilm. During acidification, the biofilm continued to grow and its thickness almost doubled from ∼ 30 μm before acidification to ∼ 60 μm after acidification. These results demonstrated that E. coli DH5α biofilm was able to provide a protective and sustainable barrier on mortar surfaces against medium to strong sulfuric acid attack. -- Highlights: •Effectiveness of E.coli DH5α biofilm to prevent MICD was studied. •Conditions that lead to MICD were simulated by chemical acidification. •Biofilm-covered mortar specimens were exposed to sulfuric acid solutions. •The presence of biofilm helped reduce the chemically-induced mortar deterioration. •Biofilm remained alive and continued to grow during the acidification process.
