    University students' substance abuse and risky sex contribute to sexually transmitted diseases (STDs). We develop and empirically test a formative theoretical model of sexual temptation involving substance abuse (cigarettes, alcohol, and marijuana), safe sexual behavior (use of condom/barrier for oral and vaginal intercourse), risky sexual behavior (unprotected sex and multiple sexual partners), and STDs: gonorrhea, HIV, and genital herpes. We simultaneously explore these constructs, controlling membership in social groups (fraternity/sorority, varsity athlete, and club sports) and perceived norm of substance abuse. A total of 687 American university students completed the National College Health Assessment (NCHA). We use structural equation modeling (SEM) to test the goodness of fit between our formative theoretical model and actual data. Results reveal the following discoveries: membership in campus social groups is positively associated with STDs, whereas perceived norm of peer substance abuse is negatively related to STDs. Under the influence of substance abuse, we test three outcomes of sexual temptation as related to STDs. Those who have no sex do not contract STDs. For those who fall into temptation and have sex, substance abuse is more strongly related to risky sex which leads to STDs than safe sex which does not. Those engaging in risky sex have significantly higher cognitive impairment than those practicing safe sex. Substance abuse contributes to STDs through risky sex only. Those having risky sex suffer higher cognitive impairment than those practicing safe sex. We provide novel implications to policy makers, practitioners, and researchers.

    Despite the vast literature examining disparities in medical care, little is known about racial/ethnic and mental health disparities in sexual health care. The objective of this study was to assess disparities in safe sex counseling and resultant behavior among a patient population at risk of negative sexual health outcomes. We conducted a cross-sectional analysis among a sample of substance dependent men and women in a metropolitan area in the United States. Multiple logistic regression models were used to explore the relationship between race/ethnicity (non-Hispanic black; Hispanic; non-Hispanic white) and three indicators of mental illness (moderately severe to severe depression; any manic episodes; ≥ 3 psychotic symptoms) with two self-reported outcomes: receipt of safe sex counseling from a primary care physician and having practiced safer sex because of counseling. Among 275 substance-dependent adults, approximately 71% (195/275) reported ever being counseled by their regular doctor about safe sex. Among these 195 subjects, 76% (149/195) reported practicing safer sex because of this advice. Blacks (adjusted odds ratio (AOR): 2.71; 95% confidence interval (CI): 1.36,5.42) and those reporting manic episodes (AOR: 2.41; 95% CI: 1.26,4.60) had higher odds of safe sex counseling. Neither race/ethnicity nor any indicator of mental illness was significantly associated with practicing safer sex because of counseling. Those with past manic episodes reported more safe sex counseling, which is appropriate given that hypersexuality is a known symptom of mania. Black patients reported more safe sex counseling than white patients, despite controlling for sexual risk. One potential explanation is that counseling was conducted based on assumptions about sexual risk behaviors and patient race. There were no significant disparities in self-reported safer sex practices because of counseling, suggesting that increased counseling did not differentially affect safe sex behavior

    This study aims to investigate the relationship between social support and non-safe use of nicotine and alcohol among medical students, in relation to other contributing factors. Data were collected during 2002-2003. Participants (N = 135), medical students at the Democritus University of Thrace, Alexandroupolis, Greece, were allocated into groups per sex according to their smoking and alcohol drinking patterns. Comparisons were made with respect to rating scores on measures assessing perceived social support, psychopathological problems, stressful life events, physical health, and satisfaction with life. Data were analyzed using chi-square, Mann-Whitney U test, and factor analysis. Female students' non-safe use of licit substances is positively related to higher scores on perceived social support and lower scores on psychopathological dimensions. Despite some limitations of this study, findings bring about implications on antismoking and antialcoholic campaigns.

  9. Development of Self-Remediating Packaging for Safe and Secure Transport of Infectious Substances.

    2006-11-01

    As George W. Bush recognized in November 2001, "Infectious diseases make no distinctions among people and recognize no borders." By their very nature, infectious diseases of natural or intentional (bioterrorist) origins are capable of threatening regional health systems and economies. The best mechanism for minimizing the spread and impact of infectious disease is rapid disease detection and diagnosis. For rapid diagnosis to occur, infectious substances (IS) must be transported very quickly to appropriate laboratories, sometimes located across the world. Shipment of IS is problematic since many carriers, concerned about leaking packages, refuse to ship this material. The current packaging does not have any ability to neutralize or kill leaking IS. The technology described here was developed by Sandia National Laboratories to provide a fail-safe packaging system for shipment of IS that will increase the likelihood that critical material can be shipped to appropriate laboratories following a bioterrorism event or the outbreak of an infectious disease. This safe and secure packaging method contains a novel decontaminating material that will kill or neutralize any leaking infectious organisms; this feature will decrease the risk associated with shipping IS, making transport more efficient. 3 DRAFT4

  10. What should it take to describe a substance or product as 'sperm-safe'.

    Male reproductive potential continues to be adversely affected by many environmental, industrial and pharmaceutical toxins. Pre-emptive testing for reproductive toxicological (side-)effects remains limited, or even non-existent. Many products that come into direct contact with spermatozoa lack adequate testing for the absence of adverse effects, and numerous products that are intended for exposure to spermatozoa have only a general assumption of safety based on the absence of evidence of actual harm. Such assumptions can have unfortunate adverse impacts on at-risk individuals (e.g. couples who are trying to conceive), illustrating a clear need for appropriate up-front testing to establish actual 'sperm safety'. After compiling a list of general areas within the review's scope, relevant literature and other information was obtained from the authors' personal professional libraries and archives, and supplemented as necessary using PubMed and Google searches. Review by co-authors identified and eliminated errors of omission or bias. This review provides an overview of the broad range of substances, materials and products that can affect male fertility, especially through sperm fertilizing ability, along with a discussion of practical methods and bioassays for their evaluation. It is concluded that products can only be claimed to be 'sperm-safe' after performing objective, properly designed experimental studies; extrapolation from supposed predicate products or other assumptions cannot be trusted. We call for adopting the precautionary principle, especially when exposure to a product might affect not only a couple's fertility potential but also the health of resulting offspring and perhaps future generations.

    In this study, the chemical substance flow of hydrogen fluoride (hydrofluoric acid, HF) in domestic chemical industries in 2014 was analyzed in order to provide a basic material and information for the establishment of organized management system to ensure safety during HF applications. A total of 44,751 tons of HF was made by four domestic companies (in 2014); import amount was 95,984 tons in 2014 while 21,579 tons of HF was imported in 2005. The export amount of HF was 2180 tons, of which 2074 ton (China, 1422 tons, U.S. 524 tons, and Malaysia, 128 tons) was exported for the manufacturing of semiconductors. Based on the export and import amounts, it can be inferred that HF was used for manufacturing semiconductors. The industries applications of 161,123 tons of HF were as follows: manufacturing of basic inorganic chemical substance (27,937 tons), manufacturing of other chemical products such as detergents (28,208 tons), manufacturing of flat display (24,896 tons), and manufacturing of glass container package (22,002 tons). In this study, an analysis of the chemical substance flow showed that HF was mainly used in the semiconductor industry as well as glass container manufacturing. Combined with other risk management tools and approaches in the chemical industry, the chemical substance flow analysis (CSFA) can be a useful tool and method for assessment and management. The current CSFA results provide useful information for policy making in the chemical industry and national systems.

    Fine-needle aspiration (FNA) cytology is well accepted as a safe, reliable, minimally invasive, and cost-effective method for the diagnosis of salivary gland lesions. Salivary gland neoplasms are often difficult to diagnose because of morphologic heterogeneity and a variety of epithelial metaplastic changes. Hence, a number of salivary gland FNA specimens yield indeterminate results. For indeterminate FNA specimens, the suspicious-for-malignancy (SFM) category is used when a specific neoplasm falls short in quantity or quality for the criteria for malignancy. Therefore, the findings are not sufficient for a conclusive diagnosis of malignancy. This study was designed to evaluate the risk of malignancy (ROM) for the SFM group at 5 tertiary medical centers worldwide with the aforementioned criteria. Among 12,606 salivary gland FNA cases between 1997 and 2014, 276 (2.2%) were reported to be SFN. Specifically, 114 suspicious cases (41%) had histological follow-up. Histological follow-up of the 114 suspicious cases showed 95 malignant tumors indicating a risk of malignancy (ROM) of 83.3%. The ROM varied between 74% and 88% for the 5 participating institutions, and a Fisher's exact test with significance set to p<.05 showed no significant difference in ROM among the institutions (p = .78). Overall, 83.3% of SFM salivary gland FNA specimens turned out to be malignant; there was no significant interinstitutional variability in the ROMs. The SFM category for salivary gland FNA is very homogeneous, and the ROMs are quite similar worldwide.

    Full Text Available Introduction: Unsafe sexual behaviors as important risky behaviors can expose individuals and society to dangerous infectious disease such as AIDS and viral hepatitis. Considering the high prevalence of unsafe sexual behaviors, this study aimed to determine the effect of educational programs to encourage safe sexual behaviors among substance abusers referred to substance abuse treatment centers in Hamadan, Western Iran by applying the theory of planned behavior. Materials & Methods: This quasi-experimental study was performed on 104 men substance abusers (52 participants in each of the control and intervention groups referred to substance abuse treatment centers in Hamadan. Data collection tool was a questionnaire containing demographic information and the theory of planned behavior constructs. Before the educational program, questionnaires were completed by both groups. After the pretest in both groups, participants in the intervention group participated in four educational sessions designed based on the theory of planned behavior. Two months after the end of program, posttest was performed. Data was analyzed using independent T-test, chi-square, fisher exact test, McNemar’s test and multiple linear regressions using SPSS-16. Results: After educational intervention, the mean scores of the theory constructs (attitude toward behavior, subjective norms, behavioral control, behavioral intention and behaviors, in the intervention group increased significantly (P<0.05, despite the fact, changes were not significant in the control group. Conclusion: Implementation of educational courses to encourage safe sexual behaviors based on the theory of planned behavior can be beneficial for substance abusers referred to substance abuse treatment centers.

  19. Considering the summation of the effect of harmful substances during the calculation of the environmentally safe waste water discharge

    Sokolov, A. K.

    2017-09-01

    This article presents the technique of assessing the maximum allowable (standard) discharge of waste waters with several harmful substances into a water reservoir. The technique makes it possible to take into account the summation of their effect provided that the limiting harmful indices are the same. The expressions for the determination of the discharge limit of waste waters have been derived from the conditions of admissibility of the effect of several harmful substances on the waters of a reservoir. Mathematical conditions of admissibility of the effect of wastewaters on a reservoir are given for the characteristic combinations of limiting harmful indices and hazard classes of several substances. The conditions of admissibility of effects are presented in the form of logical products of the sums of relative concentrations that should not exceed the value of 1. It is shown that the calculation of the process of wastewater dilution in a flowing water reservoir is possible only on the basis of a numerical method to assess the wastewater discharge limit. An example of the numerical calculation of the standard limit of industrial enterprise wastewater discharges that contain polysulfide oil, flocculant VPK-101, and fungicide captan is given to test this method. In addition to these three harmful substances, the water reservoir also contained a fourth substance, namely, Zellek-Super herbicide, above the waste discharge point. The summation of the harmful effect was taken into account for VPK-101, captan, and Zellek-Super. The reliability of the technique was tested by the calculation of concentrations of the four substances in the control point of the flowing reservoir during the estimated maximum allowable wastewater discharge. It is shown that the value of the maximum allowable discharge limit was almost two times higher for the example under consideration, taking into account that the effect of harmful substances was unidirectional, which provides a higher level

    In previous studies, naphthoquinone (NQ) compounds have been shown to be effective, selective, and ecologically safe algicides for controlling harmful algal blooming species (HABs) or winter bloom species, such as Stephanodiscus hantzschii. However, there are no reports on NQ-based algicides for use with cyanobacterial blooming species. In this study, we developed 31 NQ compounds to investigate algicides for mitigating cyanobacterial blooms. In addition, to better apply these compounds in the field, we reduced the number of production steps to develop a cost-effective algicide. In preliminary testing, we screened NQ compounds that showed the best algicidal activity on target cyanobacteria, including Aphanizomenon, Dolichospermum, Microcystis, Oscillatoria, and Nostoc species. The compound NQ 2-0 showed the highest algicidal activity (90%) at a low concentration (≥1μM) on target algae. These were very limiting algicidal effects of 1µM NQ 2-0 observed against non-target algae, such as diatoms (Stephanodiscus hantzschii, Cyclotella meneghiniana, Synedra acus, and Aulacoseira granulata) or green algae (Cosmarium bioculatum and Scenedesmus quadricauda), and the effect did not exceed 15-25% (except against S. quadricauda). NQ 2-0 (1μM) showed no eco-toxicity, as represented by the survival rates of Pseudokirchneriella subcapitata (100%), Daphnia magna (100%), and Danio rerio (100%). Additionally, a chronic eco-toxicity assessment showed no toxicity toward the survival, growth or reproduction of D. magna. Moreover, NQ 2-0 quickly dissipated from field water samples and had a half-life of approximately 3.2 days. These results suggest that NQ 2-0 could be a selective and ecologically safe algicide to mitigate harmful cyanobacterial blooms. Copyright © 2017. Published by Elsevier Inc.

    Full Text Available Background. We present a case of Actinomyces israelii causing vulvar mass suspicious for malignancy in a postmenopausal woman. Case. A 60 year-old woman presented due to a firm, nonmobile, 10 cm vulvar mass, which had been rapidly enlarging for 5 months. The mass was painful, with localized pruritus and sinus tracts oozing of serosanguinous fluid. Biopsy and cultures revealed a ruptured epidermal inclusion cyst containing granulation tissue and Actinomyces israelii. Conclusion. Actinomyces israelii may produce vulvar lesions that are suspicious for malignancy. Thus, biopsies and cultures are both mandatory while evaluating vulvar masses suspicious for malignancy.

    2014-03-01

    In this paper, we propose an integrated framework for detecting suspicious behaviors in video surveillance systems which are established in public places such as railway stations, airports, shopping malls and etc. Especially, people loitering in suspicion, unattended objects left behind and exchanging suspicious objects between persons are common security concerns in airports and other transit scenarios. These involve understanding scene/event, analyzing human movements, recognizing controllable objects, and observing the effect of the human movement on those objects. In the proposed framework, multiple background modeling technique, high level motion feature extraction method and embedded Markov chain models are integrated for detecting suspicious behaviors in real time video surveillance systems. Specifically, the proposed framework employs probability based multiple backgrounds modeling technique to detect moving objects. Then the velocity and distance measures are computed as the high level motion features of the interests. By using an integration of the computed features and the first passage time probabilities of the embedded Markov chain, the suspicious behaviors in video surveillance are analyzed for detecting loitering persons, objects left behind and human interactions such as fighting. The proposed framework has been tested by using standard public datasets and our own video surveillance scenarios.

    Individuals with obsessive-compulsive disorder (OCD) may struggle with hostility and suspicious thinking, but this has not been the subject of much research. The purpose of this study is to examine the relationship between hostility, suspicious thinking, and OCD severity. Participants included 66 outpatients in treatment for OCD, 27 in treatment for other disorders, and 68 students (n=161). All completed the Inventory of Hostility and Suspicious Thinking (IHS), a measure of psychotic thinking/paranoia, the Obsessive Compulsive Inventory-Revised (OCI-R), the Beck Depression Inventory (BDI-II), and the Beck Anxiety Inventory (BAI). As expected, the IHS was significantly positively correlated with the BAI and BDI-II. Additionally, regression analyses revealed that individuals with OCD have higher levels of hostility than students. Hostility was also significantly positively associated with increased OCD severity. Hostility and suspicious thoughts are prominent in anxiety disorders in general, and thus necessitate continued research. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  8. Money laundering: correlation between risk assessment and suspicious transactions

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available The risk assessment system was introduced in the Republic of Croatia in 2009, as a result of harmonization with international standards, especially the Directive 2005/60/EC on the prevention of the use of the financial system for the purpose of money laundering and terrorist financing. Risk assessment is an extensive concept which requires not only a legislative framework, but also the application of numerous criteria for its effective implementation in practice. Among these criteria are suspicious transactions, closely related to the assessment of the customer, transaction, product or service.The undeniable contribution of suspicious transactions to the quality of the risk assessment system will be confirmed by a statistical analysis of a number of West and East European countries. A combination of strict, but sufficiently flexible legal provisions governing the system for prevention of money laundering and terrorist financing and a statistical analysis of reported suspicious transactions will lead to conclusions that either support or represent criticism of the efficiency of application of the risk assessment system in practice.The aforementioned statistical analysis will show whether suspicious transactions are a reliable criterion for the risk assessment analysis, and whether they can be considered the only such criterion. There is a possibility that the findings of the analysis will be contradictory to those of some international studies.

However, reading ABUS examinations is very time consuming task since radiologists need to manually identify suspicious findings in all the different ABUS volumes available for each patient. Image analysis techniques to automatically link findings across volumes are required to speed up clinical workflow and make ABUS screening more efficient. In this study, we propose an automated system to, given the location in the ABUS volume being inspected (source), find the corresponding location in a target volume. The target volume can be a different view of the same study or the same view from a prior examination. The algorithm was evaluated using 118 linkages between suspicious abnormalities annotated in a dataset of ABUS images of 27 patients participating in a high risk screening program. The distance between the predicted location and the center of the annotated lesion in the target volume was computed for evaluation. The mean ± stdev and median distance error achieved by the presented algorithm for linkages between volumes of the same study was 7.75±6.71 mm and 5.16 mm, respectively. The performance was 9.54±7.87 and 8.00 mm (mean ± stdev and median) for linkages between volumes from current and prior examinations. The proposed approach has the potential to minimize user interaction for finding correspondences among ABUS volumes.

    Full Text Available Despite growing evidence for demonstrated efficacy of mindfulness in various disorders, there is a continuous concern about the relationship between mindfulness practice and psychosis. As schizotypy is part of the psychosis spectrum, we examined the relationship between long-term mindfulness practice and schizotypy in two independent studies. Study 1 included 24 experienced mindfulness practitioners (19 males from the Buddhist tradition (meditators and 24 meditation-naïve individuals (all males. Study 2 consisted of 28 meditators and 28 meditation-naïve individuals (all males. All participants completed the Schizotypal Personality Questionnaire (Raine, 1991, a self-report scale containing 9 subscales (ideas of reference, excessive social anxiety, magical thinking, unusual perceptual experiences, odd/eccentric behavior, no close friends, odd speech, constricted affect, suspiciousness. Participants of study 2 also completed the Five-Facet Mindfulness Questionnaire which assesses observing (Observe, describing (Describe, acting with awareness (Awareness, non-judging of (Non-judgment and non-reactivity to inner experience (Non-reactivity facets of trait mindfulness. In both studies, meditators scored significantly lower on suspiciousness and higher on magical thinking compared to meditation-naïve individuals and showed a trend towards lower scores on excessive social anxiety. Excessive social anxiety correlated negatively with Awareness and Non-judgment; and suspiciousness with Awareness, Non-judgment and Non-reactivity facets across both groups. The two groups did not differ in their total schizotypy score. We conclude that mindfulness practice is not associated with an overall increase in schizotypal traits. Instead, the pattern suggests that mindfulness meditation, particularly with an emphasis on the Awareness, Non-judgment and Non-reactivity aspects, may help to reduce suspiciousness and excessive social anxiety.

  12. Neural Correlates of Suspiciousness and Interactions with Anxiety during Emotional and Neutral Word Processing

    Full Text Available Suspiciousness is usually classified as a symptom of psychosis, but it also occurs in depression and anxiety disorders. Though how suspiciousness overlaps with depression is not obvious, suspiciousness does seem to overlap with anxious apprehension and anxious arousal (e.g., verbal iterative processes and vigilance about environmental threat. However, suspiciousness also has unique characteristics (e.g., concern about harm from others and vigilance about social threat. Given that both anxiety and suspiciousness have been associated with abnormalities in emotion processing, it is unclear whether it is the unique characteristics of suspiciousness or the overlap with anxiety that drive abnormalities in emotion processing.. Event-related brain potentials were obtained during an emotion-word Stroop task. Results indicated that suspiciousness interacts with anxious apprehension to modulate initial stimulus perception processes. Suspiciousness is associated with attention to all stimuli regardless of emotion content. In contrast, anxious arousal is associated with a later response to emotion stimuli only. These results suggest that suspiciousness and anxious apprehension share overlapping processes, but suspiciousness alone is associated with a hyperactive early vigilance response. Depression did not interact with suspiciousness to predict response to emotion stimuli. These findings suggest that it may be informative to assess suspiciousness in conjunction with anxiety in order to better understand how these symptoms interact and contribute to dysfunctional emotion processing.

    Full Text Available Objective: The aim of this retrospective study was to report on the diagnostic accuracy of AgNOR‐analysis as an adjunctive diagnostic tool of conventional oral exfoliative cytology taken from suspicious lesions in our clinic. Study design: Cytological diagnoses obtained from brush biopsies of macroscopically suspicious lesions of the oral mucosa from 75 patients (final diagnoses: 53 histologically proven squamous cell carcinomas, 11 leukoplakias and other inflammatory oral lesions and from 11 patients with normal mucosa as a negative control group were compared with histological and/or clinical follow‐ups. Five smears were doubtful and seven suspicious for tumor cells in the cytologic report. Number of AgNOR's were counted in 100 squamous epithelial cell‐nuclei per slide after silver‐restaining. Results: Sensitivity of our cytological diagnosis alone on oral smears for the detection of squamous carcinomas was 92.5%, specificity 100%, positive predictive value was 100% and negative 84.6%. The best cut‐off value of the mean number of AgNOR dots per nucleus distinguishing benign from malignant cells was 4.8. The percentage of nuclei with more than three AgNORs had a cut‐off level of 70%. Applying these methods to twelve doubtful or suspicious cytological diagnoses we were able to correctly establish the diagnosis of malignancy in ten cases of histologically proven cancers and to reveal benignity in two histologically proven cases. Thus we achieved a positive and negative predictive value of 100% each. Conclusions: Smears from brushings of visible oral lesions, if clinically considered as suspicious for cancer, are an easily practicable, non‐invasive, painless, safe and accurate screening method for detection of oral cancerous lesions. We conclude that AgNOR‐analysis may be a useful adjunct to other methods in routine cytological diagnosis of oral cancer that can help to solve cytologically suspicious or doubtful cases. Colour

    Pre-exposure prophylaxis (PrEP) is efficacious for HIV prevention when taken consistently; however, barriers to PrEP use are poorly understood among individuals who could benefit from PrEP, including men who have sex with men (MSM) who engage in transactional sex (i.e., sex exchanged for money or drugs). Two hundred and thirty-seven HIV-uninfected, PrEP-naive MSM reporting concurrent substance dependence and sexual risk completed a questionnaire on PrEP use barriers. Barriers to PrEP use for MSM who engaged in recent transactional sex (22 %) versus those who had not were compared using an ecological framework. Individual (e.g., HIV stigma, substance use) and structural (e.g., economic, healthcare) barriers did not differ (p > 0.05). MSM who recently engaged in transactional sex were more likely to report that anticipated stigma from primary and casual partners would be barriers to PrEP use. Assessing recent transactional sex may help identify men who may need additional counseling to avoid anticipated stigma so they can integrate PrEP into their lives.

    2014-04-01

    Full Text Available Objective: To compare pathologic results obtained via in-office transnasal fiberoptic laryngoscopy (TFL to those of subsequent direct laryngoscopy in order to assess the accuracy of TFL as a diagnostic tool. Patients: One hundred and seventeen patients with suspicious laryngeal lesions. Methods: All patients underwent in-office biopsies. All patients with malignant diagnosis were referred to treatment. All patients with benign diagnosis or carcinoma in situ were referred to direct laryngoscopy for definitive diagnosis. The pathological results of the specimens from both procedures were compared. Results: Adequate tissue for diagnostic purposes was obtained in 110 of 117 in-office transnasal fiberoptic laryngoscopy biopsies (94.0%. The biopsy results revealed invasive carcinoma in 42 patients (38.2%, carcinoma in situ (CIS in 17 patients (15.4%, and benign lesions in 51 patients (46.4%. All patients with benign pathologies and carcinoma in situ were referred to biopsy under direct laryngoscopy (five patients refused and were removed from the statistics. The final pathologies identified from the biopsies on direct laryngoscopy revealed that there was an underestimation of the transnasal fiberoptic laryngoscopy results in 33 patients (a false negative rate of 31.4%, 33/105 and an overestimation in one patient. The sensitivity of transnasal fiberoptic laryngoscopy biopsy compared with direct laryngoscopy biopsy was 70.6% and the specificity was 96.7%. Conclusions: TFL with biopsy is easy, safe, and cost-effective but raises serious doubts about its clinical value due to its low sensitivity rate for diagnosing suspicious lesions of the larynx. As such, it is recommended that all patients with a suspicious lesion diagnosed by TFL biopsy as being benign or CIS should be referred to direct laryngoscopy for verification of the findings.

    2015-08-01

    In the rules of evidence in all legal jurisdictions, medical experts are required to maintain objectivity when providing opinions. When interpreting medical evidence, doctors must recognise, acknowledge and manage uncertainties to ensure their evidence is reliable to legal decision-makers. Even in the forensic sciences such as DNA analysis, implicit bias has been shown to influence how results are interpreted from cognitive and contextual biases unconsciously operating. In cases involving allegations of child abuse there has been significant exposure in the media, popular magazines, legal journals and in the published medical literature debating the reliability of medical evidence given in these proceedings. In these cases judges have historically been critical of experts they perceived had sacrificed objectivity for advocacy by having an investment in a 'side'. This paper firstly discusses the issue of bias then describes types of cognitive biases identified from psychological research applied to forensic evidence including adversarial bias, context bias, confirmation bias and explains how terminology can influence the communication of opinion. It follows with previously published guidelines of how to reduce the risk of bias compromising objectivity in forensic practices then concludes with my own recommendations of practices that can be used by child protection paediatricians and within an organisation when conducting forensic evaluations of suspicious childhood injury to improve objectivity in formulation of opinion evidence.

  18. Suspiciousness and low self-esteem as predictors of misattributions of anger in schizophrenia spectrum disorders.

    While it is widely recognized that many with schizophrenia have significant difficulties in correctly identifying the emotions of others, less is known about the causes and correlates of particular forms of misattribution, including mistakenly seeing anger in others. One possibility is that persons with high levels of suspiciousness and low levels of self-esteem are at risk to attribute their poor feelings about themselves to the malice of others. To explore this possibility, we identified 52 persons with a schizophrenia spectrum disorder who made significant numbers of errors on the Bell-Lysaker Emotional Recognition Test. We then performed a cluster analysis based on measures of suspiciousness from the Positive and Negative Syndrome Scale and self-esteem from the Rosenberg Self-Esteem Schedule, and found the following four groups: a) High Suspiciousness/High Self-Esteem; b) Mild Suspiciousness/High Self-Esteem; c) High Suspiciousness/Low Self-Esteem; and d) Minimal Suspiciousness/Low Self-Esteem. Comparisons between groups revealed that as predicted the High Suspiciousness/Low Self-Esteem group made significantly more misattributions of anger than other groups, even when levels of depression were controlled for statistically. Implications for addressing the misattributions of anger in schizophrenia are discussed.

    Fine-needle aspiration cytology (FNAC) assists the diagnosis of thyroid malignancy. A 'suspicious for malignancy' on FNAC creates a management dilemma. The aims of this study were to investigate the malignancy rate for patients with suspicious cytology, and to describe a management approach for those with a suspicious result. A retrospective review of prospectively collected data in an endocrine surgery database was undertaken. Patients undergoing thyroidectomy with preoperative FNAC from 1992 to 2012 were analysed. Preoperative FNAC was undertaken in 2,692 patients, and the FNAC result was 'suspicious for malignancy' in 94 (3.5 %) patients. Of these, 53 (56.4 %) were malignant, with the majority 44 (83.0 %) being papillary thyroid cancer. 48 patients went straight to total thyroidectomy, 40 patients had an initial diagnostic hemithyroidectomy, and 1 patient had a diagnostic isthmusectomy. 5 patients required reoperative total thyroidectomy as an initial procedure. Of the 94 suspicious cases, 55 were reported by an unknown, presumably non-expert, thyroid cytopathologist. 38 of these cases were available for review and re-reporting by an experienced cytopathologist. On review, 28 (73.7 %) were reclassified as cytologically malignant, and all of these were confirmed as malignant on subsequent histopathology. Suspicious cytology has a high risk of malignancy. Expert thyroid cytopathology can improve diagnostic accuracy and a preoperative malignant diagnosis should be pursued to enable one-stage surgery where possible.

    The main objectives of health care for people with AIDS are to help them adjust to changing sexual status and to provide them with information on safe sex. Sections consider the risks of various types of sexual activity and safe sex education. With regard to the risk of transmitting or contracting HIV, sexual activities may be high risk, medium risk, low risk, or no risk. High-risk activities include unprotected anal or vaginal intercourse, oral-anal sexual contact, sharing sex toys, and traumatic sexual activity. Medium-risk activities include anal and vaginal intercourse using a latex condom with or without spermicide, and sex using a vaginal diaphragm or contraceptive vaginal sponge. Oral sex on a woman or oral sex on a man without ejaculation into the mouth are low-risk activities. Mutual masturbation, erotic touching, caressing and massage, kissing and non-genital licking pose no risk of infection. All general practitioners and family physicians should teach about safe sex. Prevention messages may be conveyed through individual and social counseling as well as with printed media and other forms of mass media. Messages should definitely reach prostitutes and brothel owners, as well as pre-pubertal children and older youths.

    We determined the natural history of pathologically benign cancer suspicious regions on multiparametric magnetic resonance imaging following targeted biopsy. Between January 2012 and September 2014, 330 men underwent prostate multiparametric magnetic resonance imaging. A total of 533 cancer suspicious regions were identified and scored on a Likert scale of 1 to 5 based on suspicion for malignancy with 5 indicating the highest suspicion level. Following multiparametric magnetic resonance imaging all men underwent magnetic resonance imaging-ultrasound fusion targeted prostate biopsy using ProFuse software and the ei-Nav|Artemis system (innoMedicus, Cham, Switzerland), and a computer generated 12-core random biopsy. We analyzed a cohort of 34 men with a total of 51 cancer suspicious regions who had benign prostate biopsies and underwent repeat multiparametric magnetic resonance imaging and prostate specific antigen testing at 1 year. Changes in the greatest linear measurement, the suspicion score and serum prostate specific antigen were ascertained. During 1 year the suspicion score distribution and the mean greatest linear measurement of the cancer suspicious regions decreased significantly (p resonance imaging at 1 year in men with pathologically benign cancer suspicious regions should be discouraged since it is unlikely to influence management decisions.

    To determine the influence of local contrast optimisation on diagnostic accuracy and perceived suspiciousness of digital screening mammograms. Data were collected from a screening region in the Netherlands and consisted of 263 digital screening cases (153 recalled,110 normal). Each case was available twice, once processed with a tissue equalisation (TE) algorithm and once with local contrast optimisation (PV). All cases had digitised previous mammograms. For both algorithms, the probability of malignancy of each finding was scored independently by six screening radiologists. Perceived case suspiciousness was defined as the highest probability of malignancy of all findings of a radiologist within a case. Differences in diagnostic accuracy of the processing algorithms were analysed by comparing the areas under the receiver operating characteristic curves (A{sub z}). Differences in perceived case suspiciousness were analysed using sign tests. There was no significant difference in A{sub z} (TE: 0.909, PV 0.917, P = 0.46). For all radiologists, perceived case suspiciousness using PV was higher than using TE more often than vice versa (ratio: 1.14-2.12). This was significant (P <0.0083) for four radiologists. Optimisation of local contrast by image processing may increase perceived case suspiciousness, while diagnostic accuracy may remain similar. (orig.)

    We describe a comprehensive system for learning to identify suspicious vehicle tracks from wide-area motion (WAMI) video. First, since the road network for the scene of interest is assumed unknown, agglomerative hierarchical clustering is applied to all spatial vehicle measurements, resulting in spatial cells that largely capture individual road segments. Next, for each track, both at the cell (speed, acceleration, azimuth) and track (range, total distance, duration) levels, extreme value feature statistics are both computed and aggregated, to form summary (p-value based) anomaly statistics for each track. Here, to fairly evaluate tracks that travel across different numbers of spatial cells, for each cell-level feature type, a single (most extreme) statistic is chosen, over all cells traveled. Finally, a novel active learning paradigm, applied to a (logistic regression) track classifier, is invoked to learn to distinguish suspicious from merely anomalous tracks, starting from anomaly-ranked track prioritization, with ground-truth labeling by a human operator. This system has been applied to WAMI video data (ARGUS), with the tracks automatically extracted by a system developed in-house at Toyon Research Corporation. Our system gives promising preliminary results in highly ranking as suspicious aerial vehicles, dismounts, and traffic violators, and in learning which features are most indicative of suspicious tracks.

    Early recognition and accurate diagnosis underpins melanoma survival. Identifying early melanomas arising in association with pre-existing lesions is often challenging. Clinically suspicious foci, however small, must be identified and examined histologically. This study assessed the accuracy of punch biopsy 'scoring' of suspicious foci in excised atypical pigmented skin lesions to identify early melanomas. Forty-one excised pigmented skin lesions with a clinically/dermoscopically focal area of concern for melanoma, with the suspicious focus marked prior to excision with a punch biopsy 'score' (a partial incision into the skin surface), were analysed. Melanoma was diagnosed in nine of 41 cases (22%). In eight of nine cases (89%) the melanoma was associated with a naevus, and in seven of nine (88%) cases the melanoma was identified preferentially by the scored focus. In six of nine cases (67%), the melanoma was entirely encompassed by the scored focus. In one case of melanoma in situ, the diagnostic material was identified only on further levelling through the scored focus. In 28 of 32 of non-melanoma cases (88%), the scored focus identified either diagnostic features of a particular lesion or pathological features that correlated with the clinical impression of change/atypia including altered architecture or distribution of pigmentation, features of irritation or regression. The 'punch scoring technique' allows direct clinicopathological correlation and facilitates early melanoma diagnosis by focusing attention on clinically suspicious areas. Furthermore, it does not require special expertise in ex-vivo clinical techniques for implementation. Nevertheless, in some cases examination of the lesion beyond the scored focus is also necessary to make a diagnosis of melanoma. © 2017 John Wiley & Sons Ltd.

    Ultrasound is the most frequently used imaging method to evaluate thyroid nodules. Sonographic characteristics of thyroid nodules which are concerning for malignancy are important to define the need for fine needle aspiration biopsy or open surgery. To evaluate malignancy risk of solid thyroid nodules through sonographic scoring. The effects of nodule size ≥2cm and associated pathologic cervical lymph node in scoring were examined in addition to generally excepted suspicious features. Medical data of 123 patients underwent thyroid surgery were reviewed, and 89 patients (58 females, 31 males) were included in the study. The presence and absence of each suspicious sonographic feature of thyroid nodules were scored as 1 and 0, respectively. Total ultrasound score was obtained by adding the positive ultrasound findings. Differently from the literature, nodule size ≥2cm and associated pathologic cervical node were added in scoring criteria. The diagnostic performance of nodule characteristics for malignancy and the effect of total US score to discriminate malignant and benign disease were calculated. A significant relationship was found between malignancy and hypoechogenity, border irregularity, intranodular vascularity, and microcalcification (p<0.05). Pathologic cervical node was observed predominantly in association with malignant nodules. Positive predictive value of suspicious cervical node for malignancy was 67%, similar to microcalcification. Nodule size ≥2cm was not distinctive for diagnosis of malignancy. The number of suspicious sonographic features obtained with receiver operating characteristic analysis to discriminate between malignant and benign disease was three. Sonographic scoring of thyroid nodules is an effective method for predicting malignancy. The authors suggest including associated pathologic node in the scoring criteria. Further studies with larger cohorts will provide more evidence about its importance in sonographic scoring. Copyright

    Pew research polls report 62 percent of U.S. adults get news on social media (Gottfried and Shearer, 2016). In a December poll, 64 percent of U.S. adults said that “made-up news” has caused a “great deal of confusion” about the facts of current events (Barthel et al., 2016). Fabricated stories spread in social media, ranging from deliberate propaganda to hoaxes and satire, contributes to this confusion in addition to having serious effects on global stability. In this work we build predictive models to classify 130 thousand news tweets as suspicious or verified, and predict four subtypes of suspicious news – satire, hoaxes, clickbait and propaganda. We demonstrate that neural network models trained on tweet content and social network interactions outperform lexical models. Unlike previous work on deception detection, we find that adding syntax and grammar features to our models decreases performance. Incorporating linguistic features, including bias and subjectivity, improves classification results, however social interaction features are most informative for finer-grained separation between our four types of suspicious news posts.

    Full Text Available Phishing is the spoofing of Internet websites or emails aimed at tricking users into entering sensitive information, with such goals as financial or identity theft. The current study sought to determine whether age is associated with increased susceptibility to phishing and whether tests of executive functioning can predict phishing susceptibility. A total of 193 cognitively intact participants, 91 younger adults and 102 older adults, were primarily recruited through a Psychology department undergraduate subject pool and a gerontology research registry, respectively. The Executive Functions Module from the Neuropsychological Assessment Battery and the Iowa Gambling Task were the primary cognitive predictors of reported phishing suspiciousness. Other predictors included age group (older vs. younger, sex, education, race, ethnicity, prior knowledge of phishing, prior susceptibility to phishing, and whether or not browsing behaviors were reportedly different in the laboratory setting versus at home. A logistic regression, which accounted for a 22.7% reduction in error variance compared to the null model and predicted phishing suspiciousness with 73.1% (95% CI [66.0, 80.3] accuracy, revealed three statistically significant predictors: the main effect of education (b = 0.58, SE = 0.27 and the interactions of age group with prior awareness of phishing (b = 2.31, SE = 1.12 and performance on the Neuropsychological Assessment Battery Mazes test (b = 0.16, SE = 0.07.

    Imparting bad news had always been an unpleasant task for the physician, as shown from ancient years to our days. In the healthcare sector and as far as the cancer patient is concerned, the imparting of bad news is performed by the patient's doctor within a therapeutic relationship of course. The fundamental question is how a therapist could tailor the information to any patient and if "Is it possible to determine who should be told what, when and how ?". The aim of this paper was to describe the suspicious character or type of personality thoroughly so that any physician can make a diagnosis and tailor the information strategy to the patient's needs. As method of research was used the qualitative method through groups with doctors and nurses, while research within groups lasted for 5 years. The degree of informing of the suspicious personality in the range "minimal - small - medium - large - very large" is : the degree of denial varies between large and very large. The degree of informing varies between medium and small and sometimes minimal. Informing the Family: The hardest family to deal with. Pay attention to litigious mania. Avoid confrontation or be drawn into agreeing with the family views.

    Recently a EULAR-taskforce defined arthralgia suspicious for progression to RA, in order to allow inclusion of homogeneous sets of arthralgia patients in clinical studies. This longitudinal study aimed (i) to validate this definition in arthralgia patients in whom rheumatologists felt that imminent RA was more likely than other arthralgias [clinically suspect arthralgia (CSA)], that is, the target population fulfilling the entry criterion, and (ii) to explore the performance in arthralgia patients who were referred to secondary care prior to rheumatological evaluation, hence ignoring the entry criterion. The definition was assessed in 241 Dutch patients identified with CSA by rheumatologists and 113 patients referred to the Umeå university hospital with recent-onset arthralgia in small joints. The external reference was arthritis development definition (⩾3/7 parameters present) had an increased risk for developing arthritis compared with definition-negative CSA patients (hazard ratio = 2.1, 95% CI: 0.9, 4.7). The sensitivity was 84% and the positive predictive value 30%. In arthralgia patients in whom the definition was applied before rheumatological evaluation, a positive definition was neither sensitive (10%) nor predictive (positive predictive value 3%). The EULAR definition of arthralgia suspicious for progression to RA is sensitive when used to support the rheumatologist's opinion on imminent RA. This validation study shows that the definition, when used as designed, further homogenizes patients that rheumatologists consider at risk for RA. To arrive at a high specificity, the clinical definition needs to be combined with biomarkers.

    There is no information about the frequency of malignancy specifically in the case of thyroid nodules with highly suspicious sonographic features, but with two fine needle aspiration (FNA) showing benign cytology. This was the objective of the study. Subjects and methods: We report the results of 105 patients with thyroid nodules considered 'highly suspicious' according to the ultrasonographic classification of American Thyroid Association, in whom FNA revealed benign cytology on two occasions (interval of 6 months). Results: Thyroidectomy was performed in 11 cases due to desire of the patient or significant growth of the nodule. In these patients, cytology continued to be benign in 9, was non-diagnostic in 1, and suspicious in 1. Histology revealed papillary carcinoma in only one nodule. In patients in whom a third FNA was obtained for this study (n = 94), cytology continued to be benign in 86, became non-diagnostic in 5, indeterminate in 2, and suspicious in 1. The last 8 patients (with non-benign cytology) were submitted to thyroidectomy and histology revealed malignancy in only one nodule. Conclusion: The rate of malignancy found here for nodules with highly suspicious sonographic features, even after two FNA showing benign cytology, was 2%. We believe that in these cases, the continuation of follow-up consisting of ultrasound at intervals of 2 years may still be adequate. (author)

    Full Text Available Background: Preoperative ultrasound (US and eventually US-guided fine-needle aspiration cytology (FNAC of suspicious axillary lymph nodes (ALN is a standard procedure in the work-up of suspicious breast lesions. Preoperative US FNAC may prevent sentinel node biopsy (SNB procedure in 24-30% of patients with early stage breast carcinoma. The aim of this study was to evaluate the institutional results of this preoperative diagnostic procedure. Materials and Methods: A total of 182 cases of preoperative FNAC of suspicious ALN where retrieved from the pathology files. The results were compared with the final histology and staging. False negative (FN FNAC cases were reviewed and possibly missed metastatic cases (2 were immunostained with the epithelial marker AE1/AE3. Results: There were no false positives, whereas 16 cases were FN. In all but one case the FN′s represented sampling error. Half of the 16 FN cases in this series were macrometastases. Discussion: About 83% of the preoperatively aspirated cases were N+, indicating that a radiologically suspicious ALN has a very high risk of being metastatic. Preoperative US guided FNAC from radiologically suspicious ALN is highly efficient in detecting metastases. Depending on national guidelines, a preoperative, positive ALN FNAC might help to stratify the patients as to SNB and/or ALN dissection.

    Intelligent medical systems based on supervised and unsupervised artificial neural networks are applied to the automatic visualization and classification of suspicious lesions in breast MRI. These systems represent an important component of future sophisticated computer-aided diagnosis systems and enable the extraction of spatial and temporal features of dynamic MRI data stemming from patients with confirmed lesion diagnosis. By taking into account the heterogenity of the cancerous tissue, these techniques reveal the malignant, benign and normal kinetic signals and and provide a regional subclassification of pathological breast tissue. Intelligent medical systems are expected to have substantial implications in healthcare politics by contributing to the diagnosis of indeterminate breast lesions by non-invasive imaging.

    Background: In 1996, Donovan and colleagues represented a scoring system for better prediction of Hirschsprung disease (HD). Objectives: Our objective was to devise another scoring system that uses a checklist of radiologic and clinical signs to determine the probability of HD in suspicious patients. Patients and Methods: In a diagnostic accuracy study, 55 children with clinical manifestations of HD that referred to a training hospital from 1998 to 2011 were assessed. A checklist was used to evaluate the items proposed by contrast enema (CE), based on six subscales, including transitional zone, rectosigmoid index (RSI), irregular contractions in aganglionic region, cobblestone appearance, filling defect due to fecaloid materials and lack of meconium defecation during the first 48 hours after birth. The patients were classified as high score and low score. Sensitivity, specificity, positive predictive value and negative predictive value of our scoring system were calculated for identifying HD, in comparison with pathologically proved or ruled out HD. Results: Of the 55 patients, 36 (65.4%) cases had HD and 19 (34.6%) cases were without HD. In the HD group, 32 patients showed high scores and four patients had low scores. The sensitivity and specificity of our diagnostic scoring system were 88.9% (95% CI: 78.6% - 99.1%) and 84.2% (95% CI: 68.7% - 100%), respectively. Moreover, positive predictive value (PPV) and negative predictive value (NPV) were 91.4% (95% CI: 82.1% - 100%) and 80% (95% CI: 62.5% - 97.5%), respectively. Conclusions: Our new scoring system of CE is a useful diagnostic method in HD. If a patient’s score is high, that patient is highly suspicious to HD and reversely, when one’s score is low, the patient presents a reduced probability to be diagnosed with HD. PMID:25901256

    Although substance abuse is frequently encountered in men receiving services in violence treatment settings, systematic study of these 'dual-problem' men has lagged. This study had two main objectives: (1) the characterization of psychoactive substance abuse disorders in a naturalistic sample of men in domestic violence treatment; and (2) clarification of the role of substance abuse on the sociodemographic, personality, psychosocial, and abuse characteristics of dual-problem men. Fifty-three adult men who were attending domestic violence treatment were recruited. They were administered the Addiction Severity Index, the Conflicts Tactics Scale, Structured Clinical Diagnostic Interview, the 16PF and the Symptoms Checklist-90. Partners, when available, were asked to provide corroboration. Sixty-three percent of the men had a current diagnosis of psychoactive substance abuse or dependence, while 92.5% had a lifetime diagnosis. Of the former, the majority was diagnosed as multiply dependent on alcohol and other drugs. As the severity of the substance abuse increased, so too did the dangerousness and frequency of abusive behaviors. Moreover, dual-problem men reported more hostility, apprehension, frustration and suspiciousness and past arrests than did their violence-only cohorts as well as a history of multiple (unsuccessful) treatments for substance abuse. These findings suggest that the trend toward multiple drug complaints seen in other clinical milieus is also being confronted in conjugal violence settings. In addition to the greater therapeutic challenge such dual-problem men present, these findings speak to the need to investigate integrated treatment approaches to improve the outlook of men grappling with both conjugal violence and multiple substance abuse problems.

    Purpose: To automatically identify and outline suspicious regions of recurrent or residual disease in the prostate bed using Dynamic Contrast Enhanced-MRI (DCE-MRI) in patients after prostatectomy. Methods: Twenty-two patients presenting for salvage radiotherapy and with identified Gross Tumor Volume (GTV) in the prostate bed were retrospectively analyzed. The MRI data consisted of Axial T2weighted-MRI (T2w) of the pelvis: resolution 1.25×1.25×2.5 mm; Field of View (FOV): 320×320 mm; slice thickness=2.5mm; 72 slices; and Dynamic Contrast Enhanced MRI (DCE-MRI)–12 series of T1w with identical spatial resolution to T2w and at 30–34s temporal resolution. Unsupervised pattern recognition was used to decompose the 4D DCE data as the product W.H of weights W of k patterns H. A well-perfused pattern Hwp was identified and the weight map Wwp associated to Hwp was used to delineate suspicious volumes. Threshold of Wwp set at mean(Wwp)+S*std(Wwp), S=1,1.5,2 and 2.5 defined four volumes labeled as DCE1.0 to DCE2.5. These volumes were displayed on T2w and, along with GTV, were correlated with the highest pre-treatment PSA values, and with pharmacokinetic analysis constants. Results: GTV was significantly correlated with DCE2.0(ρ= 0.60, p<0.003), and DCE 2.5 (ρ=0.58, p=0.004)). Significant correlation was found between highest pre-treatment PSA and GTV(ρ=0.42, p<0.049), DCE2.0(ρ= 0.52, p<0.012), and DCE 2.5 (ρ=0.67, p<<0.01)). Kruskal-Wallis analysis showed that Ktrans median value was statistically different between non-specific prostate bed tissue NSPBT and both GTV (p<<0.001) and DCE2.5 (p<<0.001), but while median Ve was statistically different between DCE2.5 and NSPBT (p=0.002), it was not statistically different between GTV and NSPBT (p=0.054), suggesting that automatic volumes capture more accurately the area of malignancy. Conclusion: Software developed for identification and visualization of suspicions regions in DCE-MRI from post-prostatectomy patients has

    Proactive detection of incidents is required to decrease the cost of security incidents. This paper focusses on the automatic early detection of suspicious behavior of pickpockets with track-based features in a crowded shopping mall. Our method consists of several steps: pedestrian tracking, feature computation and pickpocket recognition. This is challenging because the environment is crowded, people move freely through areas which cannot be covered by a single camera, because the actual snatch is a subtle action, and because collaboration is complex social behavior. We carried out an experiment with more than 20 validated pickpocket incidents. We used a top-down approach to translate expert knowledge in features and rules, and a bottom-up approach to learn discriminating patterns with a classifier. The classifier was used to separate the pickpockets from normal passers-by who are shopping in the mall. We performed a cross validation to train and evaluate our system. In this paper, we describe our method, identify the most valuable features, and analyze the results that were obtained in the experiment. We estimate the quality of these features and the performance of automatic detection of (collaborating) pickpockets. The results show that many of the pickpockets can be detected at a low false alarm rate.

The particles (reagent A) coated by streptavidin and biotinylated HBsAb (reagent B) were mixed in different proportions, then neutralized with serum whose the COI of HBsAg > 20 by ELISA in order to identify the activity of HBsAb in confirmatory reagent. 30 pieces of HBsAg weak positive serum neutralized with the confirmatory reagent, the serum were considered to be positive if rate of decline of HBsAg COI > 50%. The results were compared to Roche confirmatory Kit. Confirmatory reagent was able to neutralized with HBsAg. 24 of 30 pieces of HBsAg weak positive samples were judged to be positive, while 6 poeces were negative. The ELISA comfirm method is fully consistent with Roche confirmatory Kit. The ELISA confirmatory test for suspicious HBsAg positive samples is a simple, accurate and low cost initial validation method, After further clinical trials, should be widely applied.

    The convergent communication network will play an important role as a single platform to unify heterogeneous networks and integrate emerging technologies and existing legacy networks. Although there have been proposed many feasible solutions, they could not become convergent frameworks since they mainly focused on converting functions between various protocols and interfaces in edge networks, and handling functions for multiple services in core networks, e.g., the Multi-protocol Label Switching (MPLS) technique. Software-defined networking (SDN), on the other hand, is expected to be the ideal future for the convergent network since it can provide a controllable, dynamic, and cost-effective network. However, SDN has an original structural vulnerability behind a lot of advantages, which is the centralized control plane. As the brains of the network, a controller manages the whole network, which is attractive to attackers. In this context, we proposes a novel solution called adaptive suspicious prevention (ASP) mechanism to protect the controller from the Denial of Service (DoS) attacks that could incapacitate an SDN. The ASP is integrated with OpenFlow protocol to detect and prevent DoS attacks effectively. Our comprehensive experimental results show that the ASP enhances the resilience of an SDN network against DoS attacks by up to 38%.

    Regular screening through white light inspection of the entire oral mucosa is the most important examination method to identify precancerous lesions and early oral carcinoma. Additionally, the physiologic autofluorescence of the oral mucosa has been described as a novel screening method for the detection of mucosal lesions that are not visible by white light. This study aimed to evaluate the sensitivity and specificity of the autofluorescence examination. Seventy-eight patients were examined in this study. All of them suffered from suspicious oral mucosal lesions. Two different investigation methods were applied: the standard examination by white light and an examination by a novel light source of 400 nm that evoked a green light emission (>500 nm) in normal mucosa. It was proposed that malignant oral mucosal lesions show different autofluorescence characteristics than the green autofluorescence of healthy mucosa. Red autofluorescence indicated SCC with a sensitivity of 20% and a specificity of 98%. The results showed that dysplasia and carcinoma could be identified with a sensitivity of 96% and a specificity of 18% by using the autofluorescence method. The sensitivity decreased according to the grade of mucosal keratosis and was influenced by the localisation of the lesion. In conclusion, benign as well as malignant oral lesions could not be distinguished by a diminished autofluorescence signal. A red autofluorescence signal, however, could indicate cancerous processes of the oral mucosa.

    As much as 5% of prostate biopsies yield findings equivocal for malignancy even for skilled uropathologist; such "grey zone" lesions have been addressed in many ways, although the acronym ASAP (atypical small acinar proliferation) is the most widely used when referring to an atypical focus suspicious, but not diagnostic, for malignancy. Since the introduction of this diagnostic category more than 20 years ago, debate has ensued over its histological characterization and clinical significance. Pathology reporting of ASAP, commonly based on strict morphological criteria and traditional immunohistochemical markers such as basal cell antibodies, has been improved by recent availability of novel immunohistochemical markers such as AMACR and ERG. Further pathological issues, such as the role of pre-analytical variables, number of tissue levels, interobserver variability, and association with prostatic intraepithelial neoplasia also play a role in the optimal assessment of ASAP. Apart from diagnostic issues, a major issue is ASAP predictive value for prostate cancer on repeat biopsy. Therefore, attempts have been made to identify clinical and biological parameters that could predict subsequent diagnosis of malignancy as well as define time and modality of repeat biopsy. Finally, pathological features of cancers detected after a previous ASAP diagnosis are compared with those diagnosed at first prostate biopsy.

    Our objective is to facilitate semi-automated detection of suspicious access to EHRs. Previously we have shown that a machine learning method can play a role in identifying potentially inappropriate access to EHRs. However, the problem of sampling informative instances to build a classifier still remained. We developed an integrated filtering method leveraging both anomaly detection based on symbolic clustering and signature detection, a rule-based technique. We applied the integrated filtering to 25.5 million access records in an intervention arm, and compared this with 8.6 million access records in a control arm where no filtering was applied. On the training set with cross-validation, the AUC was 0.960 in the control arm and 0.998 in the intervention arm. The difference in false negative rates on the independent test set was significant, P=1.6×10(-6). Our study suggests that utilization of integrated filtering strategies to facilitate the construction of classifiers can be helpful.

    Mammography is the primary imaging modality for screening of breast cancer and evaluation of breast lesions (T staging). Ultrasonography is an adjunctive tool for mammographically suspicious lesions, in patients with mastopathy and as guidance for reliable histological diagnosis with percutaneous biopsy. Dynamic enhanced magnetic resonance mammography (MRM) has a high sensitivity for the detection of breast cancer, but also a high false positive diagnosis rate. In the literature, MRM is reported to have a sensitivity of 86-96%, a specificity of 64-91%, an accuracy of 79-93%, a positive predictive value (PPV) of 77-92% and a negative predictive value (NPV) of 75-94%. In unclarified cases, metabolic imaging using fluorine-18 fluorodeoxyglucose positron emission tomography (FDG PET) can be performed. In the literature, FDG PET is reported to have a sensitivity of 64-96%, a specificity of 73-100%, an accuracy of 70-97%, a PPV of 81-100% and an NPV of 52-89%. Furthermore, PET or PET/CT using FDG has an important role in the assessment of N and M staging of breast cancer, the prediction of tumour response in patients with locally advanced breast cancer receiving neoadjuvant chemotherapy, and the differentiation of scar and cancer recurrence. Other functional radionuclide-based diagnostic tools, such as scintimammography with sestamibi, peptide scintigraphy or immunoscintigraphy, have a lower accuracy than FDG PET and, therefore, are appropriate only for exceptional indications.

    Full Text Available Dengue is a common tropical infection that is still a global health threat. An important laboratory parameter for the management of dengue is platelet count. Platelet count is an useful test for diagnosis and following up on dengue. However, errors in laboratory reports can occur. This study is a retrospective analysis on laboratory report data of complete blood count in cases with suspicious dengue in a medical center within 1 month period during the outbreak season on October, 2015. According to the studied period, there were 184 requests for complete blood count for cases suspected for dengue. From those 184 laboratory report records, errors can be seen in 12 reports (6.5%. This study demonstrates that there are considerable high rate of post-analytical errors in laboratory reports. Interestingly, the platelet count in those erroneous reports can be unreliable and ineffective or problematic when it is used for the management of dengue suspicious patients.

    To determine the malignancy rate of bone lesions identified on FDG PET/CT in patients who have undergone CT-guided biopsy because of the suspicion of malignancy. This single-centre retrospective study spanned eight consecutive years and included all patients who underwent both FDG PET/CT and CT-guided bone biopsy because of the suspicion of malignancy. The positive predictive value (PPV) for malignancy was calculated, and different patient and imaging characteristics were compared between malignant and benign bone lesions. Of 102 included patients with bone lesions that all showed FDG uptake exceeding mediastinal uptake, bone biopsy showed a malignant lesion in 91 patients, yielding a PPV for malignancy of 89.2 % (95 % CI 81.7 - 93.9 %). In the 94 patients with bone lesions that showed FDG uptake exceeding liver uptake, bone biopsy showed a malignant lesion in 83 patients, yielding a PPV for malignancy of 88.3 % (95 % CI 80.1 - 93.5 %). Higher age, bone marrow replacement of the lesion seen on CT, expansion of the lesion seen on CT, and presence of multifocal lesions on FDG PET/CT were significantly more frequent in patients with malignant lesions than in those with benign bone lesions (P = 0.044, P = 0.009, P = 0.015, and P = 0.019, respectively). Furthermore, there was a trend towards a higher incidence of cortical destruction (P = 0.056) and surrounding soft tissue mass (P = 0.063) in patients with malignant bone lesions. The PPV for malignancy of suspicious bone lesions identified on FDG PET/CT is not sufficiently high to justify changes in patient management without histopathological confirmation. Nevertheless, ancillary patient and imaging characteristics may increase the likelihood of a malignant bone lesion. (orig.)

  11. Autofluorescence guided diagnostic evaluation of suspicious oral mucosal lesions: opportunities, limitations, and pitfalls

    Wide-filed autofluorescence examination is currently considered as a standard of care for screening and diagnostic evaluation of early neoplastic changes of the skin, cervix, lung, bladder, gastrointestinal tract and oral cavity. Naturally occurring fluorophores within the tissue absorb UV and visible light and can re-emit some of this light at longer wavelengths in the form of fluorescence. This non-invasive tissue autofluorescence imaging is used in optical diagnostics, especially in the early detection of cancer. Usually, malignant transformation is associated with thickening of the epithelium, enhanced cellular density due to increased nuclear cytoplasmic ratio which may attenuate the excitation leading to a decrease in collagen autofluorescence. Hence, dysplastic and cancerous tissues often exhibit decreased blue-green autofluorescence and appear darker compared to uninvolved mucosa. Currently, there are three commercially available devices to examine tissue autofluorescence in the oral cavity. In this study we used the oral cancer screening device IdentafiTM 3000 to examine the tissue reflectance and autofluorescence of PML and confounding lesions of the oral cavity. Wide-field autofluorescence imaging enables rapid inspection of large mucosal surfaces, to aid in recognition of suspicious lesions and may also help in discriminate the PML (class 1) from some of the confounding lesions (class II). However, the presence of inflammation or pigments is also associated with loss of stromal autofluorescence, and may give rise to false-positive results with widefield fluorescence imaging. Clinicians who use these autofluorescence based oral cancer screening devices should be aware about the benign oral mucosal lesions that may give false positivity so that unnecessary patient's anxiety and the need for scalpel biopsy can be eliminated.

    Objective: Evaluating correlation estimation between diagnostic ultrasound (U.S.) of breast lesions and fine needle aspiration cytology (FNAC), and the correlation between cytology and histology (I) of these lesions undergo surgery. Materials and methods: In 2010 we performed 1589 ultrasound breast. We identified 210 suspicious lesions to be subjected to FNAC, which was performed with pathologist on site, and extemporaneous analysis of the sample to assess their appropriateness. We classified the lesions in 5 ultrasound (U) classes according to the criteria defined by Echographic BIRADS Lexicon. The results of cytology were classified in 5 classes (C) according to the guidelines of F.O.N.Ca.M. Then we evaluated the diagnostic correlation between U.S. and FNAC, and between FNAC and Histology. Results: The distribution of lesions in U classes was: 57U2, 55U3, 36U4 and 62U5. The diagnostic concordance between U and FNAC was 96.7%, with a sensitivity of 98%, specificity 93%, negative and positive predictive value respectively of 94.9% and 97.3%, and diagnostic accuracy of 96.6%. The 98 patients with C4-C5 lesions were subjected to surgery and the histology confirmed high-grade malignancy of lesions with a concordance of 99.7%. Conclusions: Having achieved high diagnostic concordance between U and FNAC, and then between FNAC and histology, we may say that the FNAC, less invasive and traumatic for the patient than needle biopsy (CB), may be still a valid method when performed with pathologist on-site to assess the adequacy of the sample taken.

    For many years cyanamide (CAS no. 420-04-2) was not commercially available due to its unstable nature. Since about 1965 the former "Süddeutsche Kalkstickstoffwerke AG" (current name: AlzChem Trostberg GmbH) developed a special stabilizing system. It was to be investigated to which Class (e.g. "Corrosive Substances", Class 8) or Division (e.g. "Self-reactive Substances", Division 4.1) of the International Regulations for the Transport of Dangerous Goods cyanamide (pure or as a 50% solution in water) should be assigned and based on this which maximum quantities are allowed to transport e.g. in tanks. Cyanamide is used for the synthesis of pharmaceutical and agrochemical actives, biocides, dyestuffs and fine chemicals. During the last years cyanamide was tested at BAM and AQura. The results and an appraisal are presented in this paper. Thus, cyanamide should be classified according to the UN Recommendations on the Transport of Dangerous Goods in Class 8, UN number 2922 (50% solution in water) and UN number 2923 (pure substance) respectively, packaging group III, danger labels 8+6.1. Cyanamide, 50% solution in water, can be transported in portable tanks under specific conditions.

    1990-01-01

    The disposal of hydrogen is often required in the operation of an experimental facility that contains hydrogen. Whether the vented hydrogen can be discharged to the atmosphere safely depends upon a number of factors such as the flow rate and atmospheric conditions. Calculations have been made that predict the distance a combustible mixture can extend from the point of release under some specified atmospheric conditions. Also the quantity of hydrogen in the combustible cloud is estimated. These results can be helpful in deciding of the hydrogen can be released directly to the atmosphere, or if it must be intentionally ignited. 15 refs., 5 figs., 2 tabs.

    2016-05-01

    Tonsillectomy is one of the most common procedures performed by Ear, Nose, and Throat surgeon. Usually, the procedure is carried out as an inpatient surgery. With the increasing need to reduce healthcare costs, spare precious hospital beds, and shorten elective surgery lists, there is currently a trend towards performing tonsillectomy on a daycare basis. A prospective review of all tonsillectomies performed at the University Malaya Medical Center was undertaken for the year 2013. Demographic details, qualifying indications, and complication rates were evaluated. There was no incidence of primary hemorrhage among the 96 tonsillectomies performed. There was no significant correlation in terms of secondary hemorrhage between inpatient and day-case tonsillectomy (P=0.54). Only two patients required revision surgery to stop post-tonsillectomy bleeding. None of the patients required blood transfusion, and there were no mortalities. Daycare tonsillectomy is safe as long as the patient is carefully selected. Both medical and social aspects should be taken into consideration. A post-operative observation period of at least 6 to 8 hours is important. The surgeon should personally review the patient post-operatively and decides if he or she should be hospitalized for observation, or safe for discharge.

    Full Text Available The consumption of a daily multivitamin among people all over the world is dramatically increasing in recent years. Most of the people believe that if vitamins are not effective, at least they are safe. However, the long term health consequences of vitamins consumption are unknown. This study aimed to assess the side effects and possible harmful and detrimental properties of vitamins and to discuss whether vitamins can be used as safe health products or dietary supplements. We performed a MEDLINE/PubMed, EMBASE, Scopus and Google Scholar search and assessed reference lists of the included studies which were published from 1993 through 2015. The studies, with an emphasis on RCTs (randomized controlled clinical trials, were reviewed. As some vitamins such as fat-soluble vitamins (vitamin A, vitamin D, vitamin E, and also some of the water-soluble vitamins like folic acid may cause adverse events and some like vitamin C is widely taken assuming that it has so many benefits and no harm, we included relevant studies with negative or undesired results regarding the effect of these vitamins on health. Our recommendation is that taking high-dose supplements of vitamins A, E, D, C, and folic acid is not always effective for prevention of disease, and it can even be harmful to the health.

    1994-03-31

    Food safety is a growing preoccupation of the health authorities and the major food companies in any European country. All the aspects of food manufacturing, from the raw materials until the product is consumed have to insure they are innoxious to human health, eliminate any harmful effects related either to food handling or consumption in domestic or common eating places, as well as protect, as much as possible, our environment. Thus, the food manufacturer has to examine step-by-step the security of the agro-cultures, their composition, but also the possible residues of pollutants and contaminants, or chemicals used to protect them against various pests and determine the possible loss or retention of these substances during technological processes. Animal raw materials should not contain veterinary drug residues or an abnormal amount of some components that result from inadequate feeding. Care should be taken to ensure the security of foods manufactured by biotechnology processes. The organisms and the whole processes used in food biotechnologies should eliminate any impurities. Any minor food ingredients, such as food additives, are under a permanent revision from the point of view of their safety. The industry reacts immediately if any justification requires that a particular food additive should not be used. In other words all the raw materials must conform to their specifications. Technological processes must create a food with an adequate microbiological quality, e.g. free of pathogens and their toxic metabolites. Any danger of microbiological contamination or accidental pollution, such as mechanical particles, chemical substances, etc. should be eliminated. The particular role of food packaging is crucial, since this is a barrier to protect the food against further parasites or microbial contamination and preserve the food from alterations due to enzymatic reactions that require particular oxygen and water activity conditions. The packaging should also

    Aim: Investigation of the diagnostic role of technetium-99m methoxyisobutylisonitrile ({sup 99m}Tc estamibi) scintimammography in non-palpable, suspicious breast lesions described as microcalcification, mass and increased density using mammography. Patients, method: 35 women with non-palpable breast lesions were enrolled in the study. Anterior, left and right lateral, ipsilateral posterior oblique images were obtained 15 min after the injection of 740 MBq of {sup 99m}Tc sestamibi. All scintigraphic images were evaluated visually and focal increased {sup 99m}Tc sestamibi uptake was accepted as malignant lesion. Breast lesions were classified as microcalcification (13 women), mammographic mass (16 women) and increased density (6 women). Excisional biopsy was performed in all of them irrespective of the scintigraphic results: Results: The focally increased {sup 99m}Tc sestamibi uptake was seen in 11 breast lesions with malignant lesions and in 4 breast lesions with benign lesions. The diffuse uptake of {sup 99m}Tc sestamibi was seen in 18 breast lesions with benign lesions and 2 breast lesions with malignant lesions. There was no false positive result of {sup 99m}Tc sestamibi in microcalcification group and three was no false negative result of the mammographic mass and increased density groups. Conclusion: Scintimammography might be a complementary method in decision making for the non-palpable, suspicious breast lesions that were evaluated as microcalcification, mass and increased density mammograpically.

    Full Text Available Abstract Objective: To determine the positive predictive value (PPV and likelihood ratio for magnetic resonance imaging (MRI characteristics of category 4 lesions, as described in the Breast Imaging Reporting and Data System (BI-RADS® lexicon, as well as to test the predictive performance of the descriptors using multivariate analysis and the area under the curve derived from a receiver operating characteristic (ROC curve. Materials and Methods: This was a double-blind review study of 121 suspicious findings from 98 women examined between 2009 and 2013. The terminology was based on the 2013 edition of the BI-RADS. Results: Of the 121 suspicious findings, 53 (43.8% were proven to be malignant lesions, with no significant difference between mass and non-mass enhancement (p = 0.846. The PPVs were highest for masses with a spiculated margin (71% and round shape (63%, whereas segmental distribution achieved a high PPV (80% for non-mass enhancement. Kinetic analyses performed poorly, except for type 3 curves applied to masses (PPV of 73%. Logistic regression models were significant for both patterns, although the results were better for masses, particularly when kinetic assessments were included (p = 0.015; pseudo R2 = 0.48; area under the curve = 90%. Conclusion: Some BI-RADS MRI descriptors have high PPV and good predictive performance-as demonstrated by ROC curve and multivariate analysis-when applied to BI-RADS category 4 findings. This may allow future stratification of this category.

  14. Can positron emission mammography help to identify clinically significant breast cancer in women with suspicious calcifications on mammography?

    2017-05-15

    To evaluate the diagnostic accuracy of positron emission mammography (PEM) for identifying malignant lesions in patients with suspicious microcalcifications detected on mammography. A prospective, single-centre study that evaluated 40 patients with suspicious calcifications at mammography and indication for percutaneous or surgical biopsy, with mean age of 56.4 years (range: 28-81 years). Patients who agreed to participate in the study underwent PEM with 18F-fluorodeoxyglucose before the final histological evaluation. PEM findings were compared with mammography and histological findings. Most calcifications (n = 34; 85.0 %) were classified as BIRADS 4. On histology, there were 25 (62.5 %) benign and 15 (37.5 %) malignant lesions, including 11 (27.5 %) ductal carcinoma in situ (DCIS) and 4 (10 %) invasive carcinomas. On subjective analysis, PEM was positive in 15 cases (37.5 %) and most of these cases (n = 14; 93.3 %) were confirmed as malignant on histology. There was one false-positive result, which corresponded to a fibroadenoma, and one false negative, which corresponded to an intermediate-grade DCIS. PEM had a sensitivity of 93.3 %, specificity of 96.0 % and accuracy of 95 %. PEM was able to identify all invasive carcinomas and high-grade DCIS (nuclear grade 3) in the presented sample, suggesting that this method may be useful for further evaluation of patients with suspected microcalcifications.

    The aim of this study was to compare ultrasonographic features in patients with lymphocytic thyroiditis (LT) and papillary thyroid carcinoma (PTC) having suspicious thyroid nodule(s) in a background of heterogeneous parenchyma and to determine the clinical and radiological predictors of malignancy. We reviewed the cases of 100 patients who underwent ultrasonography between April 2011 and October 2012, and showed suspicious thyroid nodule(s) in a background of heterogeneous parenchyma. Eight patients who did not undergo ultrasonography-guided fineneedle aspiration cytology (FNAC) and 34 cases of follow-up ultrasonography after initial FNAC were excluded. We compared the benign and malignant nodules in terms of their clinical and radiological factors. For the 58 nodules including 31 LTs (53.4%) and 27 PTCs (46.6%), the mean tumor sizes of the two groups were 0.96 cm for LT and 0.97 cm for PTC. A univariate analysis revealed that PTCs were more frequent in patients younger than 45 years and having microcalcifications than was LT. An independent predictor of PTC after adjustment was an age of <45 years. LT mimics malignancy in a background of heterogeneous parenchyma on ultrasonography. A young age of <45 years is the most important predictor of malignancy in this condition.

    2006-03-01

    We identified information critical for patient treatment on prostate needle biopsies diagnosed with prostatic intraepithelial neoplasia or atypical foci suspicious for carcinoma. A search was performed using the MEDLINE database and referenced lists of relevant studies to obtain articles addressing the significance of finding PIN or atypical foci suspicious for carcinoma on needle biopsy. There were certain results concerning PIN. 1) Low grade PIN should not be documented in pathology reports due to poor interobserver reproducibility and a relatively low risk of cancer following re-biopsy. 2) The expected incidence of HGPIN on needle biopsy is between 5% and 8%. 3) Although the diagnosis of HGPIN is subjective, interobserver reproducibility for its diagnosis is fairly high among urological pathologists, and yet only moderate among pathologists without special expertise in prostate pathology. 4) The median risk recorded in the literature for cancer following the diagnosis of HGPIN on needle biopsy is 24.1%, which is not much higher than the risk reported in the literature for repeat biopsy following a benign diagnosis. 5) The majority of publications that compared the risk of cancer in the same study following a needle biopsy diagnosis of HGPIN to the risk of cancer following a benign diagnosis on needle biopsy show no differences between the 2 groups. 6) Clinical and pathological parameters do not help stratify which men with HGPIN are at increased risk for a cancer diagnosis. 7) A major factor contributing to the decreased incidence of cancer following a diagnosis of HGPIN on needle biopsy in the contemporary era is related to increased needle biopsy core sampling, which detects many associated cancers on initial biopsy, such that re-biopsy, even with good sampling, does not detect many additional cancers. 8) It is recommended that men do not need routine repeat needle biopsy within the first year following the diagnosis of HGPIN, while further studies are needed

    Janaki Sathya, D.; Geetha, K.

    2017-12-01

    Automatic mass or lesion classification systems are developed to aid in distinguishing between malignant and benign lesions present in the breast DCE-MR images, the systems need to improve both the sensitivity and specificity of DCE-MR image interpretation in order to be successful for clinical use. A new classifier (a set of features together with a classification method) based on artificial neural networks trained using artificial fish swarm optimization (AFSO) algorithm is proposed in this paper. The basic idea behind the proposed classifier is to use AFSO algorithm for searching the best combination of synaptic weights for the neural network. An optimal set of features based on the statistical textural features is presented. The investigational outcomes of the proposed suspicious lesion classifier algorithm therefore confirm that the resulting classifier performs better than other such classifiers reported in the literature. Therefore this classifier demonstrates that the improvement in both the sensitivity and specificity are possible through automated image analysis.

    Full Text Available The progress in imaging methods enables fine needle aspiration (FNA biopsy to be performed on smaller and smaller lesions, including malignant ones (papillary microcarcinomas. The follicular variant predominates in this group, with cytological features often not permitting an unbiased interpretation. The aim of the study was to determine the degree of reliability of the “suspicious for malignancy” (SM diagnosis in material from the Institute of Oncology in Gliwice (IO. 290 primary SM diagnoses were established from 2010 to 2015 in the IO, including the consultations. None of the patients was treated surgically after the first FNA resulting in diagnostic category V (DC V. After the second FNA 80 patients underwent surgery, after the third 58, and after subsequent FNA 10. Together, 148 surgical resections were performed. Among 148 patients treated surgically, 111 were diagnosed with malignant lesions, which constitutes 75%. Predominantly – in 91 cases – the histopathological outcome was papillary carcinoma. The others were: 16 medullary carcinomas, 2 follicular carcinomas, and 2 poorly differentiated carcinoma cases. Moreover, 8 follicular adenomas and 28 nonneoplastic lesions were found. The high positive predictive value (PPV = 75% of SM diagnosis established in the IO testifies to the high reliability of this test. Diagnostic category V in FNA should be an indication for surgical treatment.

Unsafe food consumption occurs when food contains known substances that lead to short or long term illness or death (botulism) and suspect substances that are believed to lead to delayed diseases (pesticides). It also occurs when hunger or over eating contribute to long-term illness and shorter life expectancy. The costs of il...

  17. Pricing hazardous substance emissions

    Energy Technology Data Exchange (ETDEWEB)

    Staring, Knut; Vennemo, Haakon

    1997-12-31

    This report discusses pricing of emissions to air of several harmful substances. It combines ranking indices for environmentally harmful substances with economic valuation data to yield price estimates. The ranking methods are discussed and a relative index established. Given the relative ranking of the substances, they all become valued by assigning a value to one of them, the `anchor` substance, for which lead is selected. Valuations are provided for 19 hazardous substances that are often subject to environmental regulations. They include dioxins, TBT, etc. The study concludes with a discussion of other categories of substances as well as uncertainties and possible refinements. When the valuations are related to CO, NOx, SOx and PM 10, the index system undervalues these pollutants as compared to other studies. The scope is limited to the outdoor environment and does not include global warming and eutrophication. The indices are based on toxicity and so do not apply to CO{sub 2} or other substances that are biologically harmless. The index values are not necessarily valid for all countries and should be considered as preliminary. 18 refs., 6 tabs.

    2005-03-15

    To evaluate the usefulness of transabdominal ultrasonography as a screening examination in patients with suspicious gastric disease. We selected 141 patients with epigastric pain and who were found to have antral gastric wall thickening of more than 5 mm in transabdominal ultrasonography, and who underwent gastroscopy immediately following the ultrasonography examination, because we suspected that these patients had gastric disease. We measured the full thickness of the five layers of the gastric wall and evaluated the preservation of this five layered structure. We respectively compared the gastric wall thickness and the preservation of gastric layers in 26 normal, 91 gastritis, 12 gastric ulcer, and 12 gastric cancer patients, who were classified based on the gastroscopy results. The mean thicknesses of the gastric wall in the normal, gastritis, gastric ulcer and gastric cancer patients were 5.13{+-}0.14 mm, 6.71{+-}1.33 mm, 8.08{+-}2.80 mm, and 12.45{+-}3.70 mm, respectively. The gastric walls in the gastritis, gastric ulcer and gastric cancer patients were significantly thicker than that in the normal patients (p < 0.01). The gastric wall in the gastric cancer patients was significantly thicker than those in the gastritis and gastric ulcer patients (p < 0.01). However, the difference in the gastric wall thickness between the gastritis and gastric ulcer patients was not statistically significant (p > 0.01). Except for two patients with gastritis and three patients with gastric ulcer, the stratification of the gastric wall was preserved in all of the normal, gastritis and gastric ulcer patients, whereas it was disrupted in all of the patients with gastric cancer. Transabdominal ultrasonography in the fasting state may be a helpful and convenient modality, which can serve as a screening examination in the evaluation of gastric disease. Therefore, careful attention and effort are needed to evaluate the gastric wall during transabdominal ultrasonography

    Purpose Peritumoral edema may potentially harbor sarcoma cells. The extent of suspicious edema (SE) included in the treatment volume is subject to clinical judgment, balancing the risk of missing tumor cells with excess toxicity. Our goal was to determine variability in SE delineation by sarcoma radiation oncologists (RO). Material and Method Twelve expert ROs were provided with T1 Gadolinium and T2-weighted MR images of 10 patients with high-grade extremity soft tissue sarcoma. Gross tumor volume, CTV3cm (3cm longitudinal and 1.5cm radial margin) and CTV2cm (2cm longitudinal and 1cm radial margin) were contoured by a single observer. Suspicious peritumoral edema, defined as abnormal signal on T2 images, was independently delineated by all 12 ROs. Contouring agreement was analyzed using the Simultaneous Truth and Performance Level Estimation (STAPLE) algorithm and kappa statistics. Results The mean volumes of GTV, CTV2cm and CTV3cm were respectively 130 cm3 (7–413 cm3), 280cm3 and 360cm3. The mean consensus volume computed using the STAPLE algorithm at 95% confidence interval was 188cm3 (24–565cm3) with a substantial overall agreement corrected for chance (mean kappa =0.71; range: 0.32–0.87). The minimum, maximum and mean volume of suspicious edema (excluding the GTV) were 4cm3, 182cm3 and 58 cm3 (representing a median of 29% of the GTV volume). The median volume of suspicious edema not included in the CTV2cm and in the CTV3cm was 5 cm3 and 0.3cm3 respectively. There were 3 large tumors with >30cm3 of suspicious edema not included in the CTV3cm volume. Conclusion Despite the fact that SE would empirically seem to be a more subjective volume, a substantial or near-perfect inter-observer agreement was observed in SE delineation in most cases with high-grade STS of the extremity. A median of 97% of the consensus SE is within the CTV2cm (99.8% within the CTV3cm). In a minority of cases, however, significant expansion of the CTVs is required to cover SE. PMID

    Fine-needle aspiration cytology (FNAC) is a simple and reliable technique to assess breast lesions, although a definitive differential diagnosis (benignity vs. cancer) is achieved approximately in 60-70% of cases because an inadequate (C1), atypical (C3) or suspicious (C4) category is otherwise reported. A retrospective analysis of 763 cases with C3 or C4 reports was performed to define their positive predictive value (PPV), as well as the practical implications of clinical and imaging findings as for clinical decision-making. FNACs were collected from January 2003 to September 2012 at the Breast Unit of IRCCS "A.O.U. San Martino-IST" Genoa, with each being received later to definitive histology. The PPV for cancer of C3/C4 categories were computed to measure the accuracy of FNAC; moreover, the PPV was also stratified according to clinical, mammography and sonography data alone or by their combination. The PPV of C3 and C4 was 21.1% (80/380) and 84.1 % (322/383), respectively. Within each C3/C4 category, a significant direct correlation (p<0.001) between the suspicion index of clinical, mammography and sonography data and cancer detection rate was always observed. The PPV of C3/C4 stratified by the combination of clinical and imaging findings showed satisfactory values in the C3 category only when there was an agreement between clinical and imaging findings, whereas the PPV of the C4 category was always remarkably high (ranging from 92.3% to 100%). the diagnostic work-up in C4 reports or in patients with a C3 report but with an high suspicion index at clinical or imaging examination should be preferably implemented by means of a core biopsy to optimize the therapeutic planning; given a C3 report with dubious clinical and/or imaging findings, an excisional biopsy (or in alternative vacuum-assisted breast biopsy with complete removal of the nodule) should be preferably performed in order to reach a definitive histological dia gnosis with no further delay.

    Full Text Available Transfer prices are significant for both taxpayers and tax administrations because they determine in large part taxable profits of associated enterprises in different tax jurisdictions. Moreover, in the context of taxation, transfer prices must be complied with the arm’s length principle. However, Multinational Enterprises have been faced daily by conflicting rules and approaches to applying the arm’s length principle, burdensome documentation requirements, inconsistent audit standards and unpredictable competent authority outcomes. Therefore, the Committee on Fiscal Affairs launched another project on the administrative aspects of transfer pricing in 2010. On 16 May 2013 as a partial solution of this project was approved by the OECD Council the Revised Section E on Safe Harbours in Chapter IV of the Transfer Pricing Guidelines for Multinational Enterprises and Tax Authorities. The paper is focused on significant changes of newly approved chapter IV of the Transfer Pricing Guidelines for Multinational Enterprises and Tax Authorities, further on analysis of practice in this area, on advantages and disadvantages of safe harbours for taxpayers and competent authorities with aim to suggest recommendations on use of safe harbours in the Czech Republic.

    2012-01-01

    Consumption of psychotropic substances (alcohol, drugs, medication) has a major impact on complex activity performance such as driving. This issue is of relevant social interest for the high number of potentially involved subjects and the often fatale outcomes, and affects also occupational physicians because of the high number of people whose job is driving. There are still few studies trying to assess the presence of a possible association between increased risk of accident/injury at work and consumption of psychotropic substances and results are not always in agreement. In spite of such uncertainties and some Italian regulations still worth being amended by Legislator, the possible impact of consumption of psychoactive substances on driving is an issue to be still better defined for which occupational physicians may play a basic role in the field of prevention, clinics and rehabilitation.

  18. Eyes with Suspicious Appearance of the Optic Disc and Normal Intraocular Pressure: Using Clinical and Epidemiological Characteristics to Differentiate Those with and without Glaucoma.

    Directory of Open Access Journals (Sweden)

    Diego T Dias

    Full Text Available Among all glaucoma suspects, eyes with optic nerve head features suspicious or suggestive of early glaucoma are probably those that offer the greatest challenge for clinicians. In contrast with the robust longitudinal data published on ocular hypertension, there is no specific management guideline for these patients. Therefore, evaluating eyes with suspicious optic disc appearance and normal intraocular pressure (IOP, we sought to investigate potential differences in clinical and epidemiological characteristics to differentiate those with normal-tension glaucoma (NTG from those with presumed large physiological optic disc cups (pLPC. In this observational case-control study, we consecutively enrolled individuals with pLPC and NTG. All eyes had vertical cup-to-disc ratio (VCDR≥0.6 and untreated IOP<21 mmHg. Glaucomatous eyes had reproducible visual field defects. Eyes with pLPC required normal visual fields and ≥30 months of follow-up with no evidence of glaucomatous neuropathy. Clinical and epidemiological parameters were compared between groups. Eighty-four individuals with pLPC and 40 NTG patients were included. Regarding our main results, NTG patients were significantly older and with a higher prevalence of Japanese descendants (p<0.01. Not only did pLPC eyes have smaller mean VCDR, but also larger optic discs (p≤0.04. There were no significant differences for gender, central corneal thickness, and spherical equivalent (p≥0.38. Significant odds ratios (OR were found for race (OR = 2.42; for Japanese ancestry, age (OR = 1.05, VCDR (OR = 5.03, and disc size (OR = 0.04; p≤0.04. In conclusion, in patients with suspicious optic disc and normal IOP, those with older age, Japanese ancestry, smaller optic discs, and larger VCDR are more likely to have NTG, and therefore, deserve deeper investigation and closer monitoring.

  20. Cancer pain management: safe and effective use of opioids.

    Bruera, Eduardo; Paice, Judith A

    2015-01-01

    Pain remains a serious consequence of cancer and its treatment. Although significant advances have been made in providing effective cancer pain control, barriers persist. Lack of knowledge, limited time, financial restrictions, and diminished availability of necessary medications serve as significant obstacles. Safe and effective opioid use in a patient with cancer requires skill to overcome these challenges. Understanding the mechanism of action, along with the pharmacokinetics and pharmacodynamics, of opioids will lead to appropriate selection, dosing, and titration of these agents. Rotation from one opioid or route to another is an essential proficiency for oncologists. As opioid-related adverse effects often occur, the oncology team must be expert in preventing and managing constipation, nausea, sedation, and neurotoxicities. An emerging concern is overtreatment-the excessive and prolonged use of opioids in patients when these agents may produce more harm than benefit. This can occur when opioids are used inappropriately to treat comorbid psychologic issues such as anxiety and depression. Recognizing risk factors for overuse along with key components of universal precautions will promote safe use of these medications, supporting adherence and preventing diversion, thereby protecting the patient, the prescriber, and the community. Because substance use disorders are not rare in the oncology setting, attention must be given to the balance of providing analgesia while limiting harm. Caring for patients with substance misuse requires compassionate, multidisciplinary care, with input from supportive oncology/palliative care as well as addiction specialists.

    2010-06-01

    Gender differences in substance use disorders (SUDs) and treatment outcomes for women with SUDs have been a focus of research in the last 15 years. This article reviews gender differences in the epidemiology of SUDs, highlighting the convergence of male/female prevalence ratios of SUDs in the last 20 years. The telescoping course of SUDs, recent research on the role of neuroactive gonadal steroid hormones in craving and relapse, and sex differences in stress reactivity and relapse to substance abuse are described. The role of co-occurring mood and anxiety, eating, and posttraumatic stress disorders is considered in the epidemiology, natural history, and treatment of women with SUDs. Women's use of alcohol, stimulants, opioids, cannabis, and nicotine are examined in terms of recent epidemiology, biologic and psychosocial effects, and treatment. Although women may be less likely to enter substance abuse treatment than men over the course of the lifetime, once they enter treatment, gender itself is not a predictor of treatment retention, completion, or outcome. Research on gender-specific treatments for women with SUDs and behavioral couples treatment has yielded promising results for substance abuse treatment outcomes in women. Copyright 2010 Elsevier Inc.

    Hydrogen is an "environmentally friendly" fuel for future transportation and other applications, since it produces only pure ("distilled") water when it is consumed. Thus, hydrogen-powered vehicles are beginning to proliferate, with the total number of such vehicles expected to rise to nearly 100,000 within the next few years. However, hydrogen is also an odorless, colorless, highly flammable gas. Because of this, there is an important need for hydrogen safety monitors that can warn of hazardous conditions in vehicles, storage facilities, and hydrogen production plants. To address this need, IOS has developed a unique intrinsically safe optical hydrogen sensing technology, and has embodied it in detector systems specifically developed for safety applications. The challenge of using light to detect a colorless substance was met by creating chemically-sensitized optical materials whose color changes in the presence of hydrogen. This reversible reaction provides a sensitive, reliable, way of detecting hydrogen and measuring its concentration using light from low-cost LEDs. Hydrogen sensors based on this material were developed in three completely different optical formats: point sensors ("optrodes"), integrated optic sensors ("optical chips"), and optical fibers ("distributed sensors") whose entire length responds to hydrogen. After comparing performance, cost, time-to-market, and relative market need for these sensor types, the project focused on designing a compact optrode-based single-point hydrogen safety monitor. The project ended with the fabrication of fifteen prototype units, and the selection of two specific markets: fuel cell enclosure monitoring, and refueling/storage safety. Final testing and development of control software for these markets await future support.

  4. Keeping you safe by making machine tools safe

    CERN Document Server

    2012-01-01

    CERN’s third safety objective for 2012 concerns the safety of equipment - and machine tools in particular.   There are three prerequisites for ensuring that a machine tool can be used safely: ·      the machine tool must comply with Directive 2009/104/EC, ·      the layout of the workshop must be compliant, and ·      everyone who uses the machine tool must be trained. Provided these conditions are met, the workshop head can grant authorisation to use the machine tool. To fulfil this objective, an inventory of the machine tools must be drawn up and the people responsible for them identified. The HSE Unit's Safety Inspection Service produces compliance reports for the machine tools. In order to meet the third objective set by the Director-General, the section has doubled its capacity to carry out inspections: ...

  5. The supply chain of medicinal controlled substances: addressing the Achilles heel of drug diversion.

    Science.gov (United States)

    Coleman, John J

    2012-09-01

    The escalation of prescription drug abuse in the U.S. has attracted the attention of public health and safety officials as well as others puzzled by how such a tightly regulated enterprise could so easily be breached by those seeking controlled substances for nonmedical use. Prescribers and patients who use, misuse, or, in some cases, redistribute or divert these drugs have figured prominently in government strategies aimed at addressing this issue. This review departs from this paradigm and focuses on wholesale drug distributors, a highly efficient and largely behinds-the-scene link in the supply chain of controlled substances. By law, distributors are required to identify and report to the Drug Enforcement Administration (DEA) orders for controlled substances that are suspicious and may indicate drug diversion. Ten cases are examined in which distributors were each charged with failing to prevent the diversion of millions of doses of controlled substances. Special attention is given to a payment system employed by the industry that may encourage this unlawful commerce. Court records, agency and industry reports, and other published sources are used to document referenced cases and their disposition, and recommendations are offered for improving distributors' compliance with the law.

  6. Psilocybin for treating substance use disorders?

    2017-02-01

    Evidence based treatment for Substance use disorders (SUD) includes psychotherapy and pharmacotherapy. However, these are only partially effective. Hallucinogens, such as psilocybin, may represent potential new treatment options for SUD. This review provides a summary of (human) studies on the putative therapeutic effects of psilocybin, and discusses the receptor systems, brain regions and cognitive and emotional processes mediating psilocybin's effects. Psilocybin's chemical structure is similar to that of serotonin. Dysregulations in the serotonin system are associated with alterations in stress hormones, such as cortisol, and mood disorders. After psilocybin administration cortisol levels spike and activate the executive control network, with subsequent increased control over emotional processes, and relief of negative thinking and persistent negative emotions. Preliminary data of ongoing alcohol and smoking addiction studies in humans shows promising effects of psilocybin administration on substance use. Importantly, psilocybin has a low risk of toxicity and dependence and can be used safely under controlled clinical conditions. Areas covered: This paper is a narrative review based on the search terms: psilocybin, substance use disorder, addiction, depression, serotonin. Literature on potential efficacy and mechanisms of action of psilocybin in SUD is discussed. Expert commentary: Recent positive findings with psilocybin need confirmation in well-designed placebo controlled randomized trials employing a large sample size.

    To evaluate the feasibility and accuracy of a semiautomatic, three-dimensional volume of interest (3D sphere) for measuring the apparent diffusion coefficient (ADC) in suspicious breast lesions compared to conventional single-slice two-dimensional regions of interest (2D ROIs). This institutional-review-board-approved study included 56 participants with Breast Imaging Reporting and Data System 4/5 lesion. All received diffusion-weighted imaging magnetic resonance imaging prior to biopsy (b=0-1500 s/mm(2)). ADC values were measured in the lesions with both methods. Reproducibility and accuracies were compared. Area under the curve was 0.93 [95% confidence interval (CI) 0.86-0.99] for the 3D sphere and 0.91 (95% CI 0.84-0.98) for the 2D ROIs without significantly differing reproducibility (P=.45). A semiautomatic 3D sphere could reliably estimate ADC values in suspicious breast lesions without significant difference compared to conventional 2D ROIs. Copyright © 2016 Elsevier Inc.

  8. Light microscopy can reveal the consumption of a mixture of psychotropic plant and fungal material in suspicious death.

    Wiltshire, Patricia E J; Hawksworth, David L; Edwards, Kevin J

    2015-08-01

    Light microscopical examination of plant and fungal remains in the post mortem gut may be capable of demonstrating the ingestion of unexpected natural psychotropic materials. This is demonstrated here in a case in which a 'shaman' was accused of causing the death of a young man. The deceased had participated in a ceremony which involved the drinking of ayahuasca in order to induce a psychotropic experience. Ayahuasca is an infusion of Banisteriopsis caapi (ayahuasca vine), which produces a monoamine oxidase inhibitor, and one or more additional tropical plants, generally Psychotria viridis (chacruna) which produces dimethyltryptamine (DMT). The monoamine oxidase inhibitor prevents DMT from being broken down in the gut, so enabling its passage into the bloodstream and across the blood/brain barrier. Toxicological tests for DMT demonstrated the presence of this compound in the body. The deceased was reported to be in the habit of using Psilocybe semilanceata (liberty cap). This fungus (popularly called magic mushroom) contains psilocybin which is hydrolysed in the gut to psilocin; this compound mimics a serotonin uptake inhibitor, and also invokes psychotropic experiences. Microscopical examination established that the ileum and colon contained spores of Psilocybe and, in addition, pollen of Cannabis sativa and seeds of Papaver cf. somniferum (opium poppy). Both the plant species yield psychotropic substances. Palynological and mycological analysis of containers from the deceased person's dwelling also yielded abundant trace evidence of pertinent pollen and spores. The police had requested analysis for DMT but there was no screening for other psychotropic substances. Investigators were surprised that a mixture of hallucinogenic materials had been consumed by the deceased. The charge was modified from manslaughter to possession of a 'Class A' drug as the deceased had been consuming psychotropic substances not administered by the 'shaman'. Where death involving drugs

    Full Text Available In the last decade, lesbian, gay, bisexual, and transgender (LGBT students have become very visible at Historically Black Colleges and Universities (HBCUs, but this visibility is not reflected in some colleges’ student programs and activities. Only a few notable HBCUs, such as Howard University and Spelman College, have made a concerted effort. Acknowledging that the LGBT community is significant and exists, and fostering such support, comes up against a steep wall of religious tradition and doctrines, and conservative administrations. It is imperative that HBCUs address LGBT issues and create and support a safe space for students to articulate their identity. Meanwhile, many LGBT students on these campuses find voice and understanding in Black scholars and writers such as Audre Lorde’s Zami: A New Spelling of My Name and Charles Michael Smith’s Fighting Words: Personal Essays by Black Gay Men.

These are the tools of the trade in particle physics, but behind them are the racks of electronics that include power supplies, control systems and data acquisition networks.   Inside an electronics rack: danger could be lurking if the rack is not powered off. In routine operation, these are no more harmful than the home entertainment system in your living room. But unscrew the cover and it’s a different matter. Even after following appropriate training, and with formal authorisation from your group leader or equivalent to carry out electrical work or any work in the vicinity of electrical hazards, and even with extensive experience of carrying out such operations, it’s important to incorporate safe working practices into your routine. At CERN, before the racks of electronics reach their operational configurations for the accelerators and detectors, they play a vital role in test set-ups ...

    117 consecutive herniograms were reviewed for patients who had symptoms suggestive of hernia but with no evidence or inconclusive findings on physical examination. The traditional approach has been to explore patients with suspected occult hernias. The aim of this study was to assess the impact of herniography in minimizing needless groin exploration and to evaluate its safety. Thirty-three herniograms were positive and showed unilateral and bilateral inguinal hernias. There were no false positive examinations and two false negative examinations. No complications were present. Patients with positive herniograms were explored, and operative findings correlated well with herniographic findings. Twenty-four patients were referred to other specialities. Follow-up in clinic and telephone interviews showed symptomatic improvement in the majority of patients. Herniography is useful in evaluating obscure groin pain and occult hernias. It is a safe procedure and more cost effective than a negative exploration or diagnostic laparoscopy.

  13. Safe motherhood: the FIGO initiative.

    2003-09-01

    Over the last twenty years the international community-realizing that the tragedy of women dying during pregnancy and in childbirth could no longer be tolerated-launched a series of initiatives aimed at making safe motherhood a cornerstone of health services in all countries. Making pregnancy and delivery safe events is particularly complex, as it involves infrastructural and logistic, as well as technical, issues. Women die because they have no access to skilled personnel during pregnancy and at the time of delivery and because--if an emergency situation arises--they cannot reach a facility where emergency obstetric services are available. FIGO, the International Federation of Obstetrics and Gynecology-as the only global organization representing the Obstetricians of the world-decided some time ago that it could not limit its activities to proposing technical guidelines and debating scientific issues. It had to move into the field and, through its affiliated societies, help change the ability of the multitude of women in the developing world to obtain skilled attendance at birth. In 1997, plans were made to launch activities in five areas where maternal mortality was particularly high: Central America (Guatemala, Honduras, Nicaragua and El Salvador), Ethiopia, Mozambique, Pakistan, and Uganda. Five member societies from the developed world (the American College of Obstetricians and Gynecologists, the Society of Obstetricians and Gynecologists of Canada, the Italian Society of Obstetrics and Gynecology, the Royal College of Obstetricians and Gynecologists of the United Kingdom; and the Swedish Society of Obstetrics and Gynecology) agreed to provide support to their counterparts in these five selected areas. The project is now in its final stage. Results are, by and large, positive, demonstrating that, by motivating health professionals in the field and for a relatively modest financial outlay, more efficient use of existing services could be made in a sustainable

    2017-07-01

    Substance use problems are highly prevalent among youth in foster care. Such problems in adolescence have long-lasting implications for subsequent adjustment throughout adulthood and even across generations. Although several programs have demonstrated positive results in reducing substance use in at-risk youth, few studies have systemically examined how such programs work for foster youth and whether they are effective for both genders. This study examined the efficacy of KEEP SAFE, a family-based and skill-focused program designed to prevent substance use and other related health risking behaviors among youth in foster care. We hypothesized that improving the caregiver-youth relationship would lead to later reductions in youths' involvement with deviant peers, which subsequently would lead to less substance use, and that this mechanism would work comparably for both genders. A sample of 259 youth (154 girls, ages 11-17 years) in foster care and their caregivers participated in a randomized controlled trial and was followed for 18 months post-baseline. Results indicated that the intervention significantly reduced substance use in foster youth at 18 months post-baseline and that the intervention influenced substance use through two processes: youths' improved quality of relationships with caregivers at 6 months post-baseline and fewer associations with deviant peers at 12 months post-baseline. This suggests that these two processes may be fruitful immediate targets in substance use prevention programs for foster youth. We also found little gender differences in direct and mediating effects of the intervention, suggesting KEEP SAFE may be effective for both genders in foster care.

  16. Leibniz on Corporeal Substance

    Directory of Open Access Journals (Sweden)

    Peeter Müürsepp

    2016-10-01

    Full Text Available As an idealist, Gottfried Wilhelm Leibniz could not recognize anything corporeal as substantial. However, under the influence of Cartesian terminology, he devoted considerable effort to analysing the corporeal world, while not recognizing its real substantiality of course. Leibniz took the concept of substance from Plato, Aristotle and the scholastics, but developed it in two ways. It is a well-known fact that Leibniz introduced the term ‘corporeal substance’ in his letter to Antoine Arnauld dated to October 1687. In the letter, Leibniz understands an object of nature, like an animal or a plant, as ‘corporeal substance’. In the very same letter, Leibniz introduces the terms ‘indivisibility’ and ‘phenomenon’. Every corporeal substance can be real only as a unity, i.e. by being indivisible. Such entity must have a soul or at least an entelechy. In an opposite case, that entity would not be a real unity but just a phenomenon. No corporeal entity is indivisible and therefore not a substance. The paper aims at introducing Leibniz’s distinction between substances and phenomena and taking a closer look at the historicalphilosophical influences Leibniz experienced while developing his views of the corporeal world. Aristotle and Descartes will receive most of the attention, of course, as the concepts of ‘entelechy’ and ‘hylomorphism’ were introduced by the former, and the understanding of corporeal substance as determined by extension alone is part of the latter. The core of the original critique by Leibniz takes off from the properties of the continuum as well as the nature of shape, motion and extension. The case of continuum will receive special attention. It is analysed with the help of the novel approaches by Samuel Levey and Vassil Vidinsky. Leibniz was critical about our poor understanding of the continuum but his own interpretation of it was not fully consistent either. Although the new developments enable us to take a

    To improve awareness and knowledge of problematic substance use in pregnancy and to provide evidence-based recommendations for the management of this challenging clinical issue for all health care providers. This guideline reviews the use of screening tools, general approach to care, and recommendations for clinical management of problematic substance use in pregnancy. Evidence-based recommendations for screening and management of problematic substance use during pregnancy and lactation. Medline, PubMed, CINAHL, and The Cochrane Library were searched for articles published from 1950 using the following key words: substance-related disorders, mass screening, pregnancy complications, pregnancy, prenatal care, cocaine, cannabis, methadone, opioid, tobacco, nicotine, solvents, hallucinogens, and amphetamines. Results were initially restricted to systematic reviews and randomized control trials/controlled clinical trials. A subsequent search for observational studies was also conducted because there are few RCTs in this field of study. Articles were restricted to human studies published in English. Additional articles were located by hand searching through article reference lists. Searches were updated on a regular basis and incorporated in the guideline up to December 2009. Grey (unpublished) literature was also identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. The quality of evidence was rated using the criteria described in the Report of the Canadian Task Force on the Preventive Health Care. Recommendations for practice were ranked according to the method described in that report (Table 1). This guideline is intended to increase the knowledge and comfort level of health care providers caring for pregnant women who have substance use disorders. Improved access to

    Full Text Available Abstract Background Much of the unskilled and semi-skilled workforce in Thailand comprises migrant workers from neighbouring countries. While, in principle, healthcare facilities in the host country are open to those migrants registered with the Ministry of Labour, their actual healthcare-seeking preferences and practices, as well as those of unregistered migrants, are not well documented. This study aimed to describe the patterns of healthcare-seeking behaviours of immigrant workers in Thailand, emphasizing healthcare practices for TB-suspicious symptoms, and to identify the role of occupation and other factors influencing these behaviours. Methods A survey was conducted among 614 immigrant factory workers (FW, rubber tappers (RT and construction workers (CW, in which information was sought on socio-demography, history of illness and related healthcare-seeking behaviour. Mixed effects logistic regression modeling was employed in data analysis. Results Among all three occupations, self-medication was the most common way of dealing with illnesses, including the development of TB-suspicious symptoms, for which inappropriate drugs were used. Only for GI symptoms and obstetric problems did migrant workers commonly seek healthcare at modern healthcare facilities. For GI illness, FW preferred to attend the in-factory clinic and RT a private facility over government facilities owing to the quicker service and greater convenience. For RT, who were generally wealthier, the higher cost of private treatment was not a deterrent. CW preferentially chose a government healthcare facility for their GI problems. For obstetric problems, including delivery, government facilities were utilized by RT and CW, but most FW returned to their home country. After adjusting for confounding, having legal status in the country was associated with overall greater use of government facilities and being female and being married with use of both types of modern healthcare

    Full Text Available Background and Objectives: The evidence for gself.medication hypothesish (SMH in patients with dual diagnosis psychosis has been conflicting, though largely not supported, recently. But, still can SMH be a beneficial one in some patients with dual diagnosis remains a question. Methods: The study was conducted at Drug De.addiction and Treatment Centre, Department of Psychiatry, Post Graduate Institute of Medical Education and Research, Chandigarh, a Tertiary Care Hospital in India. This cross.sectional comparative study had psychotic patients with substance use disorder as cases and those without substance use disorder as controls. Demographic details, clinical information, and Brief Psychiatric Rating Scale (BPRS scores were ascertained for cases and controls. Cases were additionally administered modified Stated Reasons Scale and modified Perceived Effects Scale. Results: Case and controls were comparable on demographic details and duration of psychotic illness, but cases had significantly lower scores on BPRS. The reasons reported for substance abuse in cases were more often nonhedonistic than hedonistic. Perceived effects of major substances of abuse (alcohol, cannabis, and opioids were different. Alcohol use was associated with perceived decrease in loneliness and cannabis was associated with perceived increase in suspiciousness and delusions. Considerable match was found between reasons for taking the substances and the effects perceived. Interpretation and Conclusions: Incorporating reasons for taking substance and their perceived effects in the treatment regimen would certainly help a subset of such difficult.to.treat patients. India being a low.resource country with a scarcity of experts and specialized dual diagnosis clinics, these findings may have an important implication in the clinical practice.

  1. What is a safe lift?

    Espinoza, Kathy

    2013-09-01

    In a perfect world, a "safe" lift would be 51 pounds if the object is within 7 inches from the front of the body, if it is at waist height, if it is directly in front of the person, if there is a handle on the object, and if the load inside the box/bucket doesn't shift once lifted. If the load to be lifted does not meet all of these criteria, then it is an unsafe lift, and modifications must be made. Modifications would include lightening the load, getting help, or using a mechanical lifting device. There is always a way to turn an unsafe lift into a safer lift. An excellent resource for anyone interested in eliminating some of the hazards associated with lifting is the "Easy Ergonomics" publication from Cal/OSHA. This booklet offers practical advice on how to improve the workplace using engineering and administrative controls, problem-solving strategies and solutions, and a vast amount of ergonomics information and resources.

  2. SAFE Testing Nuclear Rockets Economically

    Several studies over the past few decades have recognized the need for advanced propulsion to explore the solar system. As early as the 1960s, Werner Von Braun and others recognized the need for a nuclear rocket for sending humans to Mars. The great distances, the intense radiation levels, and the physiological response to zero-gravity all supported the concept of using a nuclear rocket to decrease mission time. These same needs have been recognized in later studies, especially in the Space Exploration Initiative in 1989. One of the key questions that has arisen in later studies, however, is the ability to test a nuclear rocket engine in the current societal environment. Unlike the Rover/NERVA programs in the 1960s, the rocket exhaust can no longer be vented to the open atmosphere. As a consequence, previous studies have examined the feasibility of building a large-scale version of the Nuclear Furnace Scrubber that was demonstrated in 1971. We have investigated an alternative that would deposit the rocket exhaust along with any entrained fission products directly into the ground. The Subsurface Active Filtering of Exhaust, or SAFE, concept would allow variable sized engines to be tested for long times at a modest expense. A system overview, results of preliminary calculations, and cost estimates of proof of concept demonstrations are presented. The results indicate that a nuclear rocket could be tested at the Nevada Test Site for under $20 M.

    The National Return and Disposal of Unwanted Medicines Program provides a free and safe method for the disposal of unwanted and expired medicines. This stops drugs being dumped in landfill and waterways. An audit showed that over 600 tonnes of medicines are returned through the program. A substantial proportion of these medicines were still within their expiry dates. Salbutamol, insulin and frusemide are the most commonly discarded medicines. More than $2 million of public money is wasted each year. Hoarding and non-adherence to treatment contribute to waste. Health professionals may be able to help minimise waste by informing patients about the importance of completing prescribed courses of treatment, and discouraging them from hoarding medicines after reaching the safety net threshold on the Pharmaceutical Benefits Scheme. Prescribe no more than the required quantity of medicines. When starting a new therapy, prescribe a minimal quantity in case the drug is unsuitable for the patient. Advise patients to return all unwanted medicines to a pharmacy for disposal.

  4. Parental Substance Use Impairment, Parenting and Substance Use Disorder Risk

    2011-01-01

    Using data from a nationally representative sample, this study investigated substance use disorder (SUD) among respondents ages 15-54 as a function of their parents’ substance-related impairment and parents’ treatment history. Additionally, associations among maternal and paternal substance-related impairment, specific parenting behaviors, and the risk for SUD in the proband were examined. As expected, parental substance-related impairment was associated with SUD. Paternal treatment history was associated with a decreased risk for SUD in the proband, but did not appear to be associated with positive parenting practices. Results of post-hoc analyses suggested that parenting behaviors might operate differently to influence SUD risk in children where parents are affected by substance use problems compared to non-affected families. Future research is warranted to better understand the complex relationships among parental substance use, treatment, parenting behaviors, and SUD risk in offspring. Opportunities might exist within treatment settings to improve parenting skills. PMID:22112506

    1997-09-01

    To determine the useability (relevance, clarity and quality of content), applicability (ease of use) and accessibility (structure and form) of a series of new safe motherhood midwifery education modules. Questionnaire survey and focus group discussions, preceded by a two week clinical skills course and an eight day orientation to using the modules. Nursing and midwifery education institutions, regional training centres, acute-care hospital facilities and community settings in Ethiopia, Fiji, Lesotho, Mozambique and Nepal. Thirty-six teachers, 82 midwives, nurse-midwives and auxiliary nurse-midwives from practice settings, and 60 post basic midwifery students. Overall it was found that the introductory information and the technical content of the modules were easy to understand and use as were the instructions for both teachers and students. The presentation of the material was orderly and easy to follow; the language was comprehensible; and the illustrations were appropriate, clear and facilitated teaching. The teachers found that they were able to use most of the teaching/learning methods, teach most of the skills in the modules, and use the guidelines for assessing competence. The main difficulties encountered included adherence to the recommended time frame for some of the classroom sessions; the limited availability of clinical cases for teaching the specific skills in the modules and time limitations in the clinical area for practising the skills; and the provision of transport for community visits, data to complete community profiles, and time to complete other planned community activities. The students identified the need for a set of learning materials which they could take with them for future reference, and both teachers and students expressed concern about resources to support, and legislation to cover, the application of the skills taught/learned. The modules have the potential to strengthen and support the education of midwives in developing countries

  7. Safe prescribing: a titanic challenge.

    Science.gov (United States)

    Routledge, Philip A

    2012-10-01

    The challenge to achieve safe prescribing merits the adjective 'titanic'. The organisational and human errors leading to poor prescribing (e.g. underprescribing, overprescribing, misprescribing or medication errors) have parallels in the organisational and human errors that led to the loss of the Titanic 100 years ago this year. Prescribing can be adversely affected by communication failures, critical conditions, complacency, corner cutting, callowness and a lack of courage of conviction, all of which were also factors leading to the Titanic tragedy. These issues need to be addressed by a commitment to excellence, the final component of the 'Seven C's'. Optimal prescribing is dependent upon close communication and collaborative working between highly trained health professionals, whose role is to ensure maximum clinical effectiveness, whilst also protecting their patients from avoidable harm. Since humans are prone to error, and the environments in which they work are imperfect, it is not surprising that medication errors are common, occurring more often during the prescribing stage than during dispensing or administration. A commitment to excellence in prescribing includes a continued focus on lifelong learning (including interprofessional learning) in pharmacology and therapeutics. This should be accompanied by improvements in the clinical working environment of prescribers, and the encouragement of a strong safety culture (including reporting of adverse incidents as well as suspected adverse drug reactions whenever appropriate). Finally, members of the clinical team must be prepared to challenge each other, when necessary, to ensure that prescribing combines the highest likelihood of benefit with the lowest potential for harm. © 2012 The Author.

    The present study was undertaken to compare the efficacy of needle core biopsy (NCB) of the breast with fine-needle aspiration cytology (FNAC) in breast lesions (palpable and non-palpable) in the Indian set-up, along with the assessment of tumor grading with both the techniques. Fifty patients with suspicious breast lesions were subjected to simultaneous FNAC and ultrasound-guided NCB following an initial mammographic evaluation. Cases were categorized into benign, benign with atypia, suspicious and malignant groups. In cases of infiltrating duct carcinomas, grading was performed on cytological smears as well as on NCB specimens. Both the techniques were compared, and findings were correlated with radiological and excision findings. Out of 50 cases, 18 were found to be benign and 32 malignant on final pathological diagnosis. Maximum number of patients with benign diagnosis was in the fourth decade (42.11%) and malignant diagnosis in the fourth as well as fifth decade (35.48% each). Sensitivity and specificity of mammography for the diagnosis of malignancy was 84.37% and 83.33%, respectively. Sensitivity and specificity of FNAC for malignant diagnosis was 78.15% and 94.44%, respectively, and of NCB was 96.5% and 100%, respectively. But NCB had a slightly higher specimen inadequacy rate (8%). NCB improved diagnostic categorization over FNAC by 18%. Tumor grading in cases of IDC showed high concordance rate between NCB and subsequent excision biopsy (94.44%) but low concordance rate between NCB and FNAC (59.1%). NCB is superior to FNAC in the diagnosis of breast lesions in terms of sensitivity, specificity, correct histological categorization of the lesions as well as tumor grading.

    The purpose of this study was to evaluate the usefulness of 18F-FDG PET/CT (PET/CT) in suspicious recurred thyroid cancer before high dose of radioactive iodine therapy (RAI therapy). PET/CT was performed after injecting 370-555MBq of 18F-FDG in 23 patients prior to RAI therapy. RAI therapy (212 58 mCi) was performed, and thyroglobulin (Tg) and anti-thyroglobulin antibody (anti-TG ab) during TSH stimulation was measured. The interval between PET/CT and RAI scan was 41 50 day. 15 patients were confirmed as recurred thyroid cancer (pathologic diagnosis: 10), whereas 8 patients were diagnosed as remission status (pathologic diagnosis: 3). PET/CT had 80.0% (12/15) of sensitivity and 75.0% (6/8) of specificity. TG and RAI scan had 80.0% (12/15) and 75% (6/8), 80% (12/15) and 37.5% (3/8) of sensitivity and specificity, respectively. Combination of PET/CT and TG increased the sensitivity (93.3%; 14/15) and specificity (87.5%; 7/8). There was 25 suspicious lesions (19 malignant lesion, 6 benign lesion) in lesion-based study. PET/CT had 84.5% and 83.3% of sensitivity and specificity but RAI scan had 89.5% and 16.7%, respectively. Five false positive sites of RAI scan were diagnosed as fungus ball of lung, calcified mediastinal LN, and post op induced change such as suture granuloma. PET/CT revealed 80% (3/5) of them as benign lesions. Even though PET/CT had similar sensitivity with high dose of RAI scan, it had a better discriminating nature to detect benign lesion. We could diminish the unnecessary high dose of RAI therapy using FDG PET/CT.

  10. Substance abuse and child maltreatment.

    Science.gov (United States)

    Wells, Kathryn

    2009-04-01

    Pediatricians and other medical providers caring for children need to be aware of the dynamics in the significant relationship between substance abuse and child maltreatment. A caregiver's use and abuse of alcohol, marijuana, heroin, cocaine, methamphetamine, and other drugs place the child at risk in multiple ways. Members of the medical community need to understand these risks because the medical community plays a unique and important role in identifying and caring for these children. Substance abuse includes the abuse of legal drugs as well as the use of illegal drugs. The abuse of legal substances may be just as detrimental to parental functioning as abuse of illicit substances. Many substance abusers are also polysubstance users and the compounded effect of the abuse of multiple substances may be difficult to measure. Often other interrelated social features, such as untreated mental illness, trauma history, and domestic violence, affect these families.

  11. Debate: Are Benzodiazepines Appropriate Treatments for Patients with Substance Use Disorders? Yes.

    Park, Tae Woo

    Benzodiazepines are a controversial treatment for anxiety in patients with substance use disorders. Concerns include risk of addiction, overdose, and diversion. But benzodiazepines are among the most effective and well-tolerated treatments for anxiety, and are safe for the majority of patients who take them. Though not appropriate for all cases, particularly in those with an active opioid use disorder, benzodiazepines should be considered as a treatment for patients with substance use disorders after careful weighing of benefits and harms.

    To determine the cancer yield of stereotactic biopsy of suspicious calcifications identified within 24 months after breast conservation therapy (BCT). Retrospective review of stereotactic biopsies performed during 2009-2013 for suspicious calcifications in the ipsilateral breast of patients who completed BCT. 94/2773 (3.4%) had stereotactic biopsies for suspicious calcifications in the ipsilateral breast; 7/94 (7.4%) had DCIS (6) or invasive (1) cancer; 5/7 occurred in the same breast quadrant as the primary. All 7 originally had negative surgical margins (≥2 mm); 6 received whole breast irradiation, and 2 received adjuvant chemotherapy + endocrine therapy. Median time to detection was 11 months (range, 6-20 months). There was a strong association between calcification morphology (particularly pleomorphic) and likelihood of malignancy (p = 0.008). Stereotactic biopsy of calcifications identified within 24 months post-BCT has a 7% cancer yield. Tissue biopsy should be performed rather than imaging followup alone when breast calcifications have suspicious morphology. Copyright © 2017 Elsevier Inc. All rights reserved.

    MacDonald, L. H.; Guo, Y.; Schwab, K. J.

    2012-12-01

    This work presents a model for estimating global access to drinking water that meets World Health Organization (WHO) water quality guidelines. The currently accepted international estimate of global access to safe water, the WHO and United Nations Children's Fund's (UNICEF) Joint Monitoring Program (JMP) report, estimates the population with access to water service infrastructure that is classified as improved and unimproved. The JMP report uses access to improved water sources as a proxy for access to safe water, but improved water sources do not always meet drinking water quality guidelines. Therefore, this report likely overestimates the number of people with access to safe water. Based on the JMP estimate, the United Nations has recently announced that the world has reached the Millennium Development Goal (MDG) target for access to safe water. Our new framework employs a statistical model that incorporates source water quality, water supply interruptions, water storage practices, and point of use water treatment to estimate access to safe water, resulting in a figure that is lower than the JMP estimate of global access to safe water. We estimate that at least 28% of the world does not have access to safe water today, as compared to the JMP estimate of 12%. These findings indicate that much more work is needed on the international scale to meet the MDG target for access to safe water.

    Full Text Available Effects of microorganisms on building facades are responsible for aesthetic, bio-geophysical and biogeochemical deterioration. The process of cleaning of contaminated facades involves the removal and eradication of micro flora on the surface of insulation using chemical products, killing cells and eliminating all living mass, including organic ingredients. The removal of bio corrosion coating from ETICS structure by means of chemical and preservative substances (biocides is currently the only effective and most used technology. Uncontrolled leaching of the used biocides is unacceptable. Meantime, new technology for environmentally safe maintenance of ETICS is needed. Scientists have been working on replacement the biocides currently used in facades treatment with eco-friendly biocides that have no negative effects on the environment or human beings. While the eco- treatment will be available, safe dewatering of chemicals being leached from the surface of the facade could be provided by e.g. special drain systems adjusted to the building type, use and age. The paper gives an overview of the problem in context of Slovakia and examples of leaching systems designed for new and renovated buildings.

    Purpose: Peritumoral edema may harbor sarcoma cells. The extent of suspicious edema (SE) included in the treatment volume is subject to clinical judgment, balancing the risk of missing tumor cells with excess toxicity. Our goal was to determine variability in SE delineation by sarcoma radiation oncologists (RO). Methods and Materials: Twelve expert ROs were provided with T1 gadolinium and T2-weighted MR images of 10 patients with high-grade extremity soft-tissue sarcoma. Gross tumor volume, clinical target volume (CTV)3cm (3 cm longitudinal and 1.5 cm radial margin), and CTV2cm (2 cm longitudinal and 1 cm radial margin) were contoured by a single observer. Suspicious peritumoral edema, defined as abnormal signal on T2 images, was independently delineated by all 12 ROs. Contouring agreement was analyzed using the simultaneous truth and performance level estimation (STAPLE) algorithm and kappa statistics. Results: The mean volumes of GTV, CTV2cm, and CTV3cm were, respectively, 130 cm{sup 3} (7-413 cm{sup 3}), 280 cm{sup 3} and 360 cm{sup 3}. The mean consensus volume computed using the STAPLE algorithm at 95% confidence interval was 188 cm{sup 3} (24-565 cm{sup 3}) with a substantial overall agreement corrected for chance (mean kappa = 0.71; range: 0.32-0.87). The minimum, maximum, and mean volume of SE (excluding the GTV) were 4, 182, and 58 cm{sup 3} (representing a median of 29% of the GTV volume). The median volume of SE not included in the CTV2cm and in the CTV3cm was 5 and 0.3 cm{sup 3}, respectively. There were 3 large tumors with >30 cm{sup 3} of SE not included in the CTV3cm volume. Conclusion: Despite the fact that SE would empirically seem to be a more subjective volume, a substantial or near-perfect interobserver agreement was observed in SE delineation in most cases with high-grade soft-tissue sarcomas of the extremity. A median of 97% of the consensus SE is within the CTV2cm (99.8% within the CTV3cm). In a minority of cases, however, significant

    Many chemicals, natural and man-made, are progressing towards critical concentrations in environmental compartments (the atmosphere, soils, surface and groundwater bodies). In an early stage, system changes are small and no effects occur. Sudden mobilization and harmful effects can be triggered by exhausted buffering systems (e.g. acidification of soils with little and decreasing cation exchange capacities under the influence of acid deposition), by small changes in environmental conditions (e.g. imbalances in heterogenous stratospheric chemistry like in the case of the famous 'ozone hole'; 'chemical time bombs' set free from immobilisation in soils; or by particularly vulnerable states of organisms (e.g. tetra-genic and mutagenic action). Nonlinearity is not an exception but an inherent property of environmental systems which comprise many individual processes and coupled subsystems. In the following we highlight risks related to the anthropogenic perturbation of the nitrogen and sulfur cycles and those coming the release of xenobiotics into the environment. Large scale emissions of natural substances. Potential destabilization of forest ecosystems by nitrogen fertilization and acid deposition. (authors)

    Substance addiction (or drug addiction) is a neuropsychiatric disorder characterized by a recurring desire to continue taking the drug despite harmful consequences. Non-substance addiction (or behavioral addiction) covers pathological gambling, food addiction, internet addiction, and mobile phone addiction. Their definition is similar to drug addiction but they differ from each other in specific domains. This review aims to provide a brief overview of past and current definitions of substance and non-substance addiction, and also touches on the topic of diagnosing drug addiction and non-drug addiction, ultimately aiming to further the understanding of the key concepts needed for a foundation to study the biological and psychological underpinnings of addiction disorders.

    We conducted a comprehensive, multiphase laboratory evaluation of the Anthrax BioThreat Alert(®) test strip, a lateral flow immunoassay (LFA) for the rapid detection of Bacillus anthracis spores. The study, conducted at 2 sites, evaluated this assay for the detection of spores from the Ames and Sterne strains of B. anthracis, as well as those from an additional 22 strains. Phylogenetic near neighbors, environmental background organisms, white powders, and environmental samples were also tested. The Anthrax LFA demonstrated a limit of detection of about 10(6) spores/mL (ca. 1.5 × 10(5) spores/assay). In this study, overall sensitivity of the LFA was 99.3%, and the specificity was 98.6%. The results indicated that the specificity, sensitivity, limit of detection, dynamic range, and repeatability of the assay support its use in the field for the purpose of qualitatively evaluating suspicious white powders and environmental samples for the presumptive presence of B. anthracis spores.

    Ricin, a heterodimeric toxin that is present in the seeds of the Ricinus communis plant, is the biothreat agent most frequently encountered by law enforcement agencies in the United States. Even in untrained hands, the easily obtainable seeds can yield a highly toxic product that has been used in various types of threats, including "white-powder" letters. Although the vast majority of these threats are hoaxes, an impediment to accurate hazard assessments by first responders is the unreliability of rapid detection assays for ricin, such as lateral flow assays (LFAs). One of the complicating factors associated with LFAs is the incorporation of antibodies of poor specificity that cross-react with near-neighbors or with plant lectins that are capable of nonspecifically cross-linking the capture and detector antibodies. Because of the compelling and critical need to promote the interests of public safety and public health, the Department of Homeland Security conducted a comprehensive laboratory evaluation study of a commercial LFA for the rapid detection of ricin. This study was conducted using comprehensive inclusivity and exclusivity panels of ricin and near-neighbor plant materials, along with panels of lectins and "white-powders," to determine the specificity, sensitivity, limits of detection, dynamic range, and repeatability of the assay for the specific intended use of evaluating suspicious white powders and environmental samples in the field.

    Abrin is a heterodimeric toxin present in the seeds of the Abrus precatorius plant. The easily obtainable seeds can yield a highly toxic product that can be used in various types of biocrimes and terrorism-related activities, including "white-powder" letters. Although the vast majority of these threats are hoaxes, the lack of rapid and reliable detection assays for abrin, such as lateral flow assays (LFAs), can be an impediment to accurate and rapid hazard assessment. One of the complicating factors associated with LFAs is the use of antibodies of poor affinity and specificity that cross-react with near neighbors or that bind to plant lectins, which are capable of nonspecifically cross-linking the capture and detector antibodies. Because of the critical need to promote public safety and public health, we conducted a comprehensive laboratory evaluation of a commercial LFA for the rapid detection of abrin. This study was conducted using comprehensive inclusivity and exclusivity panels of abrin and near-neighbor plant materials, along with panels of lectins, related proteins, white powders, and environmental background material, to determine the sensitivity, specificity, limit of detection, dynamic range, and repeatability of the assay for the specific intended use of evaluating suspicious white powders and environmental samples for the presumptive presence of abrin.

    To identify Prader-Willi syndrome (PWS) and Angelman syndrome (AS) among fetuses with suspicious deletion of the chromosomal region 15q11-q13. In a retrospective study, data were assessed from fetuses missing chromosomal band 15q12 that underwent molecular diagnosis at the National Chen-Kung University Hospital, Tainan, Taiwan, between January 2001 and December 2012. Amniocytes were subjected to molecular testing, including fluorescence in situ hybridization (FISH) analysis, methylation-specific PCR (M-PCR), and methylation-specific multiplex-ligation-dependent probe amplification (MS-MLPA). During the 12-year study period, 26 041 amniocyte samples were analyzed at the study center and 27 (0.1%) were found to have a missing 15q12 band. A further 16 samples with a missing 15q12 band were received from other cytogenetic laboratories; as a result, 43 amniocyte samples lacking chromosomal band 15q12 underwent further molecular testing. Among these samples, 3 fetuses (7.0%) were found to have PWS (n=1) or AS (n=2). A minority of cases with missing 15q12 had deletion of the PWS/AS critical region. This finding draws attention to the subtle structural rearrangements that occur on 15q11-q13 and provides useful information for prenatal diagnosis of PWS and AS.

  19. Jumping to Conclusions Is Associated with Paranoia but Not General Suspiciousness: A Comparison of Two Versions of the Probabilistic Reasoning Paradigm

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Theoretical models ascribe jumping to conclusions (JTCs a prominent role in the pathogenesis of paranoia. While many earlier studies corroborated this account, some newer investigations have found no or only small associations of the JTC bias with paranoid symptoms. The present study examined whether these inconsistencies in part reflect methodological differences across studies. The study was built upon the psychometric high-risk paradigm. A total of 1899 subjects from the general population took part in an online survey and were administered the Paranoia Checklist as well as one of two different variants of the probabilistic reasoning task: one variant with a traditional instruction (a and one novel variant that combines probability estimates with decision judgments (b. Factor analysis of the Paranoia Checklist yielded an unspecific suspiciousness factor and a psychotic paranoia factor. The latter was significantly associated with scores indicating hasty decision making. Subjects scoring two standard deviations above the mean of the Paranoia Checklist showed an abnormal data-gathering style relative to subjects with normal scores. Findings suggest that the so-called decision threshold parameter is more sensitive than the conventional JTC index. For future research the specific contents of paranoid beliefs deserve more consideration in the investigation of decision making in schizophrenia as JTC seems to be associated with core psychosis-prone features of paranoia only.

    1999-01-01

    Substance abuse is a serious concern in the profession of nursing. The American Nurses Association (1997) estimates that 10% to 20% of nurses have substance abuse problems, and that 6% to 8% of registered nurses are impaired due to their abuse of alcohol and other drugs. Chemical dependency is considered a disease that requires treatment. Early identification and treatment of the chemically dependent nurse is important for the safety of the public and for the well-being of the nurse and her profession. This article addresses substance abuse from a biopsychosocial perspective, and includes a description of an approach to treatment and suggestions for the role of nursing administration.

With some drug like cocaine, stroke appear to be the result of a direct effect. In young subjects without other risk factors provide persuasive evidence for causality . OPIATES: Heroine is the most abused opiate drug, which is administered by injection, by snorting or by smoking. Stroke affects heroin users by diverse mechanisms,. Injectors are at risk of infections endocarditis, which carries risk for both ischemic and hemorrhagic stroke. Cerebral or subarachnoid hemorrhage usually occurs after rupture of a septic (mycotic aneurysm. Heroine users can are also at risk for hemorrhagic stroke secondary to liver failure with deranged clotting and to heroin nephropathy with uremia or malignant hypertension. In some heroin users the drug it self is directly causal due to vasculitis, hypersensitivity and immunologic changes. Embolization of foreign material to brain due to mixed of heroine with quinine can cause cerebral embolism. AMPHETAMINE AND other psychostimulants: In abuser of amphetamine hemorrhagic stroke can occur, oral, intravenous, nasal, and inhalational routes of administration have been reported. Most were chronic user, but in several patients, stroke followed a first exposure. Some of amphetamine induced intracranial hemorrhages are secondary to acute hypertension, some to cerebral vacuities, and some to a combination of two. Decongestants and diet pills: Phenylpropanolamine (PPA, an amphetamine – like drug, in decongestants and diet pills, induce acute hypertension, sever headache, psychiatric symptoms, seizures and hemorrhagic stroke.

  2. Managing Cassini Safe Mode Attitude at Saturn

    Burk, Thomas A.

    2010-01-01

    The Cassini spacecraft was launched on October 15, 1997 and arrived at Saturn on June 30, 2004. It has performed detailed observations and remote sensing of Saturn, its rings, and its satellites since that time. In the event safe mode interrupts normal orbital operations, Cassini has flight software fault protection algorithms to detect, isolate, and recover to a thermally safe and commandable attitude and then wait for further instructions from the ground. But the Saturn environment is complex, and safety hazards change depending on where Cassini is in its orbital trajectory around Saturn. Selecting an appropriate safe mode attitude that insures safe operation in the Saturn environment, including keeping the star tracker field of view clear of bright bodies, while maintaining a quiescent, commandable attitude, is a significant challenge. This paper discusses the Cassini safe table management strategy and the key criteria that must be considered, especially during low altitude flybys of Titan, in deciding what spacecraft attitude should be used in the event of safe mode.

  3. Curiosity's Autonomous Surface Safing Behavior Design

    Science.gov (United States)

    Neilson, Tracy A.; Manning, Robert M.

    2013-01-01

    The safing routines on all robotic deep-space vehicles are designed to put the vehicle in a power and thermally safe configuration, enabling communication with the mission operators on Earth. Achieving this goal is made a little more difficult on Curiosity because the power requirements for the core avionics and the telecommunication equipment exceed the capability of the single power source, the Multi-Mission Radioisotope Thermoelectric Generator. This drove the system design to create an operational mode, called "sleep mode", where the vehicle turns off most of the loads in order to charge the two Li-ion batteries. The system must keep the vehicle safe from over-heat and under-heat conditions, battery cell failures, under-voltage conditions, and clock failures, both while the computer is running and while the system is sleeping. The other goal of a safing routine is to communicate. On most spacecraft, this simply involves turning on the receiver and transmitter continuously. For Curiosity, Earth is above the horizon only a part of the day for direct communication to the Earth, and the orbiter overpass opportunities only occur a few times a day. The design must robustly place the Rover in a communicable condition at the correct time. This paper discusses Curiosity's autonomous safing behavior and describes how the vehicle remains power and thermally safe while sleeping, as well as a description of how the Rover communicates with the orbiters and Earth at specific times.

  4. Safe haven laws as crime control theater.

    Science.gov (United States)

    Hammond, Michelle; Miller, Monica K; Griffin, Timothy

    2010-07-01

    This article examines safe haven laws, which allow parents to legally abandon their infants. The main objective is to determine whether safe haven laws fit the criteria of crime control theater, a term used to describe public policies that produce the appearance, but not the effect, of crime control, and as such are essentially socially constructed "solutions" to socially constructed crime "problems." The analysis will apply the principles of crime control theater to safe haven laws. Specifically, the term crime control theater applies to laws that are reactionary responses to perceived criminal threats and are often widely supported as a way to address the crime in question. Such laws are attractive because they appeal to mythic narratives (i.e., saving an innocent child from a predator); however they are likely ineffective due to the complexity of the crime. These laws can have deleterious effects when policymakers make false claims of success and stunt public discourse (e.g., drawing attention away from more frequent and preventable crimes). This analysis applies these criteria to safe haven laws to determine whether such laws can be classified as crime control theater. Many qualities inherent to crime control theater are present in safe haven laws. For example, the laws are highly publicized, their intentions lack moral ambiguity, rare cases of success legitimize law enforcement and other agencies, and they appeal to the public sense of responsibility in preventing crime. Yet the goal of saving infant lives may be unattainable. These qualities make the effectiveness of the laws questionable and suggest they may be counterproductive. This analysis determined that safe haven laws are socially constructed solutions to the socially constructed problem of child abandonment. Safe haven laws are appropriately classified as crime control theater. It is imperative that further research be conducted to examine the effectiveness and collateral effects of safe haven laws

    Objective This study investigated whether young people’s substance use and aggressive behaviors are related to their listening to music containing messages of substance use and violence. Method Data were collected using self-administered questionnaires and from a sample of community college students aged 15-25 (N = 1056; 43% male). A structural equation modeling method was used to simultaneously assess the associations between listening to various genres of music, alcohol use, illicit drug use, and aggressive behaviors, taking into account respondents’ age, gender, race/ethnicity, and level of sensation seeking. Results Listening to rap music was significantly and positively associated with alcohol use, problematic alcohol use, illicit drug use, and aggressive behaviors when all other variables were controlled. Additionally, alcohol and illicit drug use were positively associated with listening to musical genres of techno and reggae. Control variables such as sensation seeking, age, gender and race/ethnicity were significantly related to substance use and aggressive behaviors. Conclusion The findings suggest that young people’s substance use and aggressive behaviors may be related to their frequent exposure to music containing references to substance use and violence. Conversely, music listening preference may reflect some personal predispositions or lifestyle preferences. Alternatively, substance use, aggression and music preference are independent constructs, but share common “third factors.” PMID:16608146

Our objective was to determine whether serum MIS concentrations were associated with cancerous or precancerous lesions. Blood from 30 premenopausal women was collected and serum extracted prior to their undergoing breast biopsy to assess a suspicious lesion found on imaging or physical examination. Based on biopsy results, the serum specimens were grouped as cancer (invasive or ductal carcinoma in situ, precancer (atypical hyperplasia or lobular carcinoma in situ, or benign. Findings Serum from women with cancer and precancer (p = .0009 had lower MIS levels than serum from women with benign disease. Conclusion Our findings provide preliminary evidence for MIS being associated with current breast cancer risk, which should be validated in a larger population.

  11. Monitoring moving queries inside a safe region.

    Al-Khalidi, Haidar; Taniar, David; Betts, John; Alamri, Sultan

    2014-01-01

    With mobile moving range queries, there is a need to recalculate the relevant surrounding objects of interest whenever the query moves. Therefore, monitoring the moving query is very costly. The safe region is one method that has been proposed to minimise the communication and computation cost of continuously monitoring a moving range query. Inside the safe region the set of objects of interest to the query do not change; thus there is no need to update the query while it is inside its safe region. However, when the query leaves its safe region the mobile device has to reevaluate the query, necessitating communication with the server. Knowing when and where the mobile device will leave a safe region is widely known as a difficult problem. To solve this problem, we propose a novel method to monitor the position of the query over time using a linear function based on the direction of the query obtained by periodic monitoring of its position. Periodic monitoring ensures that the query is aware of its location all the time. This method reduces the costs associated with communications in client-server architecture. Computational results show that our method is successful in handling moving query patterns.

    An occupational therapist presented her 45-minute program called AIDS Education and Safe Sex 5 times to female mental patients in the locked ward of Cedarcrest Regional Hospital in Newington, Connecticut, to inform them about safe-sex practices and AIDS. She first administered a pretest then spoke briefly about AIDS and safe-sex practices. The lecture emphasized various important points such as no cure for AIDS exist, casual contact (e.g., kiss on the cheek, handshake) cannot transmit HIV, and effectiveness of using latex condoms. The occupational therapist spent much of her time addressing myths about AIDS and what safe-sex practices are. The patients discussed sexual abuse and dishonest partners. She administered a posttest which was the same as the pretest. Some sessions attracted more people than did other sessions. Test scores increased for every patient and for every session. They ranged from a 5% (68-73%) increase for the 3rd session to a 24% (67-91%) increase for the last session. She was not able to determine, however, whether the increased knowledge would translate into positive behavioral changes. Patients' psychiatric symptoms may have interfered with learning resulting in less than ideal improvements in knowledge. These symptoms were hypomanic behavior, restlessness, and distractibility. Perhaps other sessions with experiential techniques (e.g., putting condoms on dummies) would increase their understanding. This program helps fill the information gap not provided by the mass media which avoid mentioning safe-sex practices.

    This review focuses on alcohol and substance abuse in the context of solid-organ transplantation. Alcohol and substance abuse are common and may lead to a need for solid-organ transplantation and may also contribute to significant physical and psychologic problems that impact upon the recipient. Damaging levels of alcohol intake can occur in the absence of dependence. Alcohol or substance abuse after transplantation is associated with poor medication compliance and this may increase risk of graft loss. Intravenous drug use is associated with increased risk of infections (especially secondary to opportunistic organisms-bacterial, viral, protozoal, and others-and such infections may be more severe in the immunosuppressed), but there is only anecdotal evidence that such behavior has a worse outcome in transplant recipients. Whereas previous alcohol excess and drug use in kidney recipients are both associated with a small but statistically significantly increased risk of adverse outcomes (hazard ratio, 1.16-1.56), alcohol use within recommended guidelines after transplantation appears safe and possibly beneficial. Robust data are lacking for other organs, but those available suggest that heart transplantation is safe in individuals with a history of alcohol or substance abuse. Health specialists in drug or alcohol addiction should carefully screen all potential transplant candidates for these conditions, and where there is evidence of dependency or abuse, effective psychologic and physical treatment should be offered. Studies have shown that interventions such as psychologic intervention have improved alcohol behavior in the context of liver transplantation. Although there are no comparable studies with other solid-organ recipients, it is reasonable to expect transferable outcomes.

    This paper presents the development of sun safe controllers which are designed to keep the spacecraft power positive and thermally balanced in the event an anomaly is detected. Employed by NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE), the controllers utilize the measured sun vector and the spacecraft body rates for feedback control. To improve the accuracy of sun vector estimation, the least square minimization approach is applied to process the sensor data, which is proven to be effective and accurate. To validate the controllers, the LADEE spacecraft model engaging the sun safe mode was first simulated and then compared with the actual LADEE orbital fight data. The results demonstrated the applicability of the proposed sun safe controllers.

    Full Text Available Lumbar puncture (LP is the only way to diagnose meningitis, however some concerning points regarding its complication especially brain herniation are usually noted. Several factors including difficulties of neurologic examination especially in infants, absence of cooperation when performing the LP, incorrect myths and legal issues as well as unavailability of CT equipment , X-ray exposure and charges; makes evaluation of such requests reasonable .One hundred infants and children, 2 months to 12 years old who were suspicious to have meningitis were enrolled in this cross-sectional, descriptive study. Two groups were formed based on requesting a B.CT (Brain CT scan before LP or performing the procedure directly. Demographic and clinical parameters were analyzed among two groups using a questionnaire and CT results were recorded. Chi-square test was used for statistical analysis; P value<0.05 was considered as significant.B.CT was requested for 21 patients (case group in which the results led to postponing the procedure in 14%( 3 of cases. Toxic appearance, poor general condition, bulging fontanel and impaired consciousness (GCS score<8 were significantly related to such a decision making. There was also a trend toward ordering B.CT for those patients with recent cardiopulmonary arrest, focal signs, papilledema, hemiparesis and bradycardia. Two cases of brain herniation were identified in the control group, both had severe irritability and projectile vomiting at presentation.According to other studies, severe impairment of consciousness and presence of focal signs and symptoms are acceptable criteria for such a request, however ordering B.CT solely based on general condition or presence of a bulge fontanel seems to be unreasonable for which we couldn’t identify any supportive study. Larger scale studies considering the pediatric differential diagnosis and characteristics are required to generate proper, scientific and supportive protocols in this

    We have developed a multi-probe resonance-frequency electrical impedance spectroscope (REIS) system to detect breast abnormalities. Based on assessing asymmetry in REIS signals acquired between left and right breasts, we developed several machine learning classifiers to classify younger women (i.e., under 50YO) into two groups of having high and low risk for developing breast cancer. In this study, we investigated a new method to optimize performance based on the area under a selected partial receiver operating characteristic (ROC) curve when optimizing an artificial neural network (ANN), and tested whether it could improve classification performance. From an ongoing prospective study, we selected a dataset of 174 cases for whom we have both REIS signals and diagnostic status verification. The dataset includes 66 "positive" cases recommended for biopsy due to detection of highly suspicious breast lesions and 108 "negative" cases determined by imaging based examinations. A set of REIS-based feature differences, extracted from the two breasts using a mirror-matched approach, was computed and constituted an initial feature pool. Using a leave-one-case-out cross-validation method, we applied a genetic algorithm (GA) to train the ANN with an optimal subset of features. Two optimization criteria were separately used in GA optimization, namely the area under the entire ROC curve (AUC) and the partial area under the ROC curve, up to a predetermined threshold (i.e., 90% specificity). The results showed that although the ANN optimized using the entire AUC yielded higher overall performance (AUC = 0.83 versus 0.76), the ANN optimized using the partial ROC area criterion achieved substantially higher operational performance (i.e., increasing sensitivity level from 28% to 48% at 95% specificity and/ or from 48% to 58% at 90% specificity).

    In order to quantify the risk of malignancy of clinical and ultrasonographic features of thyroid nodules (TNs), we did a systematic review and meta-analysis of published studies. We did a literature search in MEDLINE for studies published from 1st January 1989 until 31st December 2012. Studies were considered eligible if they investigated the association between at least one clinical/ultrasonographic feature and the risk of malignancy, did not have exclusion criteria for the detected nodules, had histologically confirmed the diagnoses of malignancy, and had a univariable analysis available. Two reviewers independently extracted data on study characteristics and outcomes. The meta-analysis included 41 studies, for a total of 29678 TN. A higher risk of malignancy expressed in odds ratio (OR) was found for the following: nodule height greater than width (OR: 10.15), absent halo sign (OR: 7.14), microcalcifications (OR: 6.76), irregular margins (OR: 6.12), hypoechogenicity (OR: 5.07), solid nodule structure (OR: 4.69), intranodular vascularization (OR: 3.76), family history of thyroid carcinoma (OR: 2.29), nodule size ≥4 cm (OR: 1.63), single nodule (OR: 1.43), history of head/neck irradiation (OR: 1.29), and male gender (OR: 1.22). Interestingly, meta-regression analysis showed a higher risk of malignancy for hypoechoic nodules in iodine-sufficient than in iodine-deficient geographical areas. The current meta-analysis verified and weighed out each suspicious clinical and ultrasonographic TN feature. The highest risk was found for nodule height greater than width, absent halo sign, and microcalcifications for ultrasonographic features and family history of thyroid carcinoma for clinical features. A meta-analysis-derived grading system of TN malignancy risk, validated on a large prospective cohort, could be a useful tool in TN diagnostic work-up.

  18. PCA3 sensitivity and specificity for prostate cancer detection in patients with abnormal PSA and/or suspicious digital rectal examination. First Latin American experience.

    Prostate Cancer Gene 3 (PCA3) is a recently described and highly specific urinary marker for prostate cancer (CaP). Its introduction in clinical practice to supplement low specificity of prostate specific antigen (PSA) can improve CaP diagnosis and follow-up. However, before its introduction, it is necessary to validate the method of PCA3 detection in distinct geographic populations. Our aim was to describe for the first time in Latin America, the application of the PROGENSA PCA3 assay for PCA3 detection in urine in Chilean men and its utility for CaP diagnosis in men with an indication of prostate biopsy. Sixty-four Chilean patients (mean age, 64 years) with indication of prostate biopsy because of elevated PSA and/or suspicious digital rectal examination (DRE) were prospectively recruited. PCA3 scores were assessed from urine samples obtained after DRE, before biopsy, and compared with PSA levels and biopsy outcome. The median PSA value and mean PCA3 score were 5.8 ng/ml and 31.7, respectively. Using a cutoff PCA3 score of 35, the sensitivity and specificity for detecting CaP were 52% and 87%, respectively. The receiver operating characteristic (ROC) curve analysis showed an area under the curve of 0.77 for PCA3 and 0.57 for PSA, for the same group of patients. In patients with previous negative biopsy, PCA3 specificity increased by 2.2%. This is the first report in Latin America on the use of PCA3 in diagnosing CaP. Our results are comparable to those reported in other populations in the literature, demonstrating the reproducibility of the test. PCA3 score was highly specific and we specially recommend its use in patients with persistent elevated PSA and prior negative biopsies. Copyright © 2013 Elsevier Inc. All rights reserved.

    A lesion on an occlusal tooth surface with no cavitation and no radiographic radiolucency but in which caries is suspected owing to surface roughness, opacities, or staining can be defined as a suspicious occlusal carious lesion (SOCL). The authors' objective was to quantify the characteristics of SOCLs and their relationship to lesion depth and activity after these lesions were opened surgically. Ninety-three dentists participated in the study. When a consenting patient had an SOCL, information was recorded about the tooth, lesion, treatment provided, and, if the SOCL was opened surgically, its lesion depth. The Rao-Scott cluster-adjusted χ 2 test was used to evaluate associations between lesion depth and color, roughness, patient risk, and luster. The authors analyzed 1,593 SOCLs. Lesion color varied from yellow/light brown (40%) to dark brown/black (47%), with 13% other colors. Most (69%) of SOCLs had a rough surface when examined with an explorer. Over one-third of the SOCLs (39%) were treated surgically. Of the 585 surgically treated SOCLs, 61% had dentinal caries. There were statistically significant associations between lesion depth and color (P = .03), luster (P = .04), and roughness (P = .01). The authors classified 52% of the patients as being at elevated caries risk. The authors found no significant associations between lesion depth and patient risk (P = .07). Although statistically significant, the clinical characteristics studied do not provide accurate guidance for making definitive treatment decisions and result in high rates of false positives. Given that 39% of the opened lesions did not have dentinal caries or were inactive, evidence-based preventive management is an appropriate alternative to surgical intervention.

    Early diagnosis and referral of oral cancer is essential. Successful implementation of clinical guidelines must include current practitioners and students. To evaluate the diagnostic accuracy of students at oral cancer screening and to assess the effectiveness of clinical referral guidelines. Fifth year dental students were randomly allocated to either control (n=19) or experimental groups (n = 18). Both received the customary training in oral diagnosis. The experimental group underwent a 2 hour workshop where the guidelines for the referral of suspicious lesions were discussed. Three months later, a set of 51 clinical cases including benign, malignant, and precancerous conditions/lesions were used to assess the screening ability of each subject. All 37 students entered the study. Sensitivity (control group) ranged from 16.7% to 66.7%; the experimental group scored from 16.7% to 83.3%. Fifty percent of the experimental students reached sensitivity values ≥ 62.5% (p = 0.01). Diagnostic specificity (control group) spanned from 80% to 93.3% (median = 50%); amongst experimental group it ranged from 82.2% to 97.8% (median = 92.8%); (p = 0.003). Concordance -control group- was X = 82.5 (SD = 3.2), and X = 88.2 (SD = 4.3) for the experimental, (p > 0.001). Cohen's kappa test was poor (K cancers urgently (p = 0.002) and left less unreferred cancers (0.04). This group also referred more precancerous lesions/conditions urgently (p = 0.02). The implementation of a clinical referral guideline at undergraduate level has proved valuable, under experimental conditions, to significantly increase diagnostic abilities of the examiners and thus to improve screening for oral cancer.

    Full Text Available To create a safe city free from natural disasters has been one of the important criteria in city planning. Since large cities have suffered from large fires caused by earthquakes, the planning of open spaces to prevent the spread of fires is part of the basic structure of city planning in Japan. Even in the feudal city of Edo, the former name of Tokyo, there had been open spaces to prevent fire disasters along canals and rivers. This paper discusses the historical evolution of open space planning, that we call landscape planning, through the experiences in Tokyo, and clarifies the characteristics and problems for achieving a safe city.

    The present status of investigations about the anticancer activity which is inherent to medicinal mushrooms, as well as their biomedical potential and future prospects are discussed. Mushroom products and extracts possess promising immunomodulating and anticancer effects, so the main biologically active substances of mushrooms responsible for immunomodulation and direct cytoto-xicity toward cancer cell lines (including rarely mentioned groups of anticancer mushroom proteins), and the mechanisms of their antitumor action were analyzed. The existing to date clinical trials of mushroom substances are mentioned. Mushroom anticancer extracts, obtained by the different solvents, are outlined. Modern approaches of cancer treatment with implication of mushroom products, including DNA vaccinotherapy with mushroom immunomodulatory adjuvants, creation of prodrugs with mushroom lectins that can recognize glycoconjugates on the cancer cell surface, development of nanovectors etc. are discussed. The future prospects of mushroom anticancer substances application, including chemical modification of polysaccharides and terpenoids, gene engineering of proteins, and implementation of vaccines are reviewed.

    Emerging adulthood has heightened risk for substance use. College students experience unique challenges, making them prone to use of alcohol, marijuana, and nonmedical use of prescription drugs. This article reviews rates of college students' substance use, risk factors, and populations at elevated risk. Consequences include legal, academic, and mental health problems; engagement in other risky behaviors; increased rates of injury; and death. Researchers, clinicians, and university administrators must identify those at greatest risk and provide prevention and intervention programs. Despite broad evidence supporting such programs, many students fail to access appropriate treatment. Future research should elucidate treatment barriers. Copyright © 2016 Elsevier Inc.

    The scientific literature concerning the public health response to the unprecedented hurricanes striking the Gulf Coast in August and September 2005 has focused mainly on assessing health-related needs and surveillance of injuries, infectious diseases, and other illnesses. However, the hurricanes also resulted in unintended hazardous substances releases in the affected states. Data from two states (Louisiana and Texas) participating in the Hazardous Substances Emergency Events Surveillance (HSEES) system were analyzed to describe the characteristics of hazardous substances releases in industrial settings associated with Hurricanes Katrina and Rita. HSEES is an active multi-state Web-based surveillance system maintained by the Agency for Toxic Substances and Disease Registry (ATSDR). In 2005, 166 hurricane-related hazardous substances events in industrial settings in Louisiana and Texas were reported. Most (72.3%) releases were due to emergency shut downs in preparation for the hurricanes and start-ups after the hurricanes. Emphasis is given to the contributing causal factors, hazardous substances released, and event scenarios. Recommendations are made to prevent or minimize acute releases of hazardous substances during future hurricanes, including installing backup power generation, securing equipment and piping to withstand high winds, establishing procedures to shutdown process operations safely, following established and up-to-date start-up procedures and checklists, and carefully performing pre-start-up safety reviews.

    {sup 99m}Tc-MDP scintimammography(SM) was performed at the time of the preoperative bone scan in patients with suspicious breast cancer. These patients also had {sup 99m}Tc-MIBI scintimammography before or after the bone scan. The purpose of this report is to compare {sup 99m}Tc-MDP SM and {sup 99m}Tc-MIBI SM with the surgical results. Scintimammography with {sup 99m}Tc-MDP was performed in 20 patients with palpable mass and radiologic suspicion or proven diagnosis of breast cancer preoperatively. Patients ranged in age from 34 to 72. No male patient was included. Both prone lateral and supine anterior views were obtained for 10 min each 10-15min after IV administration of 740 MBq of {sup 99m}Tc-MDP. The {sup 99m}Tc-MIBI scintimammography was also performed before surgery. {sup 99m}Tc-MIBI SM began in 5 min. postinjection of 740MBq of {sup 99m}Tc-MIBI with prone lateral views for 10 min. Scintimammography was evaluated as positive or negative for presence or absence of focal localization of the tracers and the results were compared to histological findings. Breast cancer was histologically diagnosed in all patients ( 16 infiltrating ductal carcinoma, 2 comedocarcinoma, 1 phyllodes tumor, 1 paget disease). The size of tumor mass ranged 1.5-3 cm. Lymph node metastasis was found in 4 patients by the histologic examination. The uptake of {sup 99m}Tc-MDP in breast cancer was noted in all patients except two. One of the two patients was in post excisional biopsy state and the other was also negative in the MIBI scan. There was MDP axillary node uptake in 5 patients. Two of 5 patients with axillary lymph node uptake were false positive but they were all positive with {sup 99m}Tc-MIBI scintimammography. Two masses found in MIBI scan of a patients cannot be separated o the MDP scan. It showed more diffuse uptake than MIBI scan. The concordance between MDP-SM with MIBI-SM(similar pattern of uptake) was 45% and the remaining cases showed not focal but more diffuse uptake

  11. Perioperative Care of Prisoners: Providing Safe Care.

    Science.gov (United States)

    Smith, Francis Duval

    2016-03-01

    Correctional nurses are trained to care for prisoners in a controlled security environment; however, when a convict is transferred to a noncorrectional health care facility, the nurses there are often unfamiliar with custody requirements or how to safely care for these patients. The care of prisoners outside of prison has not been adequately investigated, and a gap exists between research and nursing education and practice. Nurses rarely have to consider how providing care for a prisoner in custody affects their practice, the potential dissonance between routine nursing care and the requirements to maintain security, or that care of prisoners in unsecured clinical areas places the nurse and other personnel at risk for physical assault or prisoner escape. Educating perioperative nurses in the care of prisoners in a public hospital environment is important for the provision of safe care and prevention of physical and emotional repercussions to personnel.

    Expansion of uranium mining in the United States is a concern to some environmental groups and sovereign Native American Nations. An approach which may alleviate some problems is to develop inherently safe in situ uranium recovery ('ISR') technologies. Current ISR technology relies on chemical extraction of trace levels of uranium from aquifers that, once mined, can still contain dissolved uranium and other trace metals that are a health concern. Existing ISR operations are few in number; however, high uranium prices are driving the industry to consider expanding operations nation-wide. Environmental concerns and enforcement of the new 30 ppb uranium drinking water standard may make opening new mining operations more difficult and costly. Here we propose a technological fix: the development of inherently safe in situ recovery (ISISR) methods. The four central features of an ISISR approach are: (1) New 'green' leachants that break down predictably in the subsurface, leaving uranium, and associated trace metals, in an immobile form; (2) Post-leachant uranium/metals-immobilizing washes that provide a backup decontamination process; (3) An optimized well-field design that increases uranium recovery efficiency and minimizes excursions of contaminated water; and (4) A combined hydrologic/geochemical protocol for designing low-cost post-extraction long-term monitoring. ISISR would bring larger amounts of uranium to the surface, leave fewer toxic metals in the aquifer, and cost less to monitor safely - thus providing a 'win-win-win' solution to all stakeholders.

    Festinger, David S; Dugosh, Karen Leggett

    2012-01-01

    Research involving substance-abusing participants is often hindered by low rates of recruitment and retention. Research suggests that monetary payment or remuneration can be an effective strategy to overcome these obstacles. This article provides a brief overview of these issues and provides data reflecting how substance-abusing participants in several of our studies used their baseline and follow-up payments. We also present research findings related to how the mode of payment (i.e., cash, check, gift card) may affect how payments are used. Overall, our findings suggest that participants use their research payments in a responsible and safe manner. Limitations and recommendations for future research are discussed.

    Little is known about treatment for pregnant and postpartum women with co-occurring substance use and depression. Funded by the National Institute of Drug Abuse, we conducted three focus groups with 18 pregnant and postpartum women in 2011 at an urban substance use treatment clinic. A semi-structured discussion guide probed for factors impacting treatment outcomes and needs. Data were analyzed using grounded theory. Women identified motivational, family, friend, romantic, and agency characteristics as facilitative or challenging to their recoveries, and desired structure (group treatment, a safe environment, and transportation) and content (attention to mental health, family, and gender-specific issues) of treatment.

    2016-06-01

    Conclusion SafeTrach is a new simplified and safe technique to perform percutaneous dilatational tracheotomy (PDT) that eliminates known risk factors compared with existing percutaneous techniques. In the present clinical study, also patients with disadvantageous anatomy not suitable for conventional PDT (CPDT) were treated without complications using SafeTrach. PDT with SafeTrach (STPDT) offers an excellent solution for patients who need tracheotomy in connection with elective ear, nose, and throat (ENT) surgery. Objectives To assess a new technique for percutaneous tracheotomy. Methods Seventeen patients were tracheotomized with STPDT using SafeTrach for the initial penetration sequence and single step dilatational techniques for the dilatational sequence. The patients represented a variety of different neck anatomies. Fifteen patients were head- and neck cancer patients that were subjects of free flap transplants. Results This study showed that STPDT was safe and easy to perform and time-efficient. The median duration of the procedure was 11.5 min and the puncture was in all cases located in the midline of the trachea either between the 2nd and 3rd tracheal ring (n = 13) or between the 3rd and 4th ring (n = 4).

    The presence of drugs in outdoor air has been established, but few investigations have been conducted indoors. This study focused on psychotropic substances (PSs) at three schools, four homes and one office in Rome, Italy. The indoor drug concentrations and the relationships with the outdoor atmosphere were investigated. The optimised monitoring procedure allowed for the determination of cocaine, cannabinoids and particulate fractions of nicotine and caffeine. In-field experiments were performed during the winter, spring and summer seasons. Psychotropic substances were observed in all indoor locations. The indoor concentrations often exceeded those recorded both outdoors at the same sites and at the atmospheric pollution control network stations, indicating that the drugs were released into the air at the inside sites or were more persistent. During winter, the relative concentrations of cannabinol, cannabidiol and tetrahydrocannabinol depended on site and indoor/outdoor location at the site. Copyright © 2014 Elsevier Ltd.

    2002-01-01

    Since the 1960s, research has been conducted into the use of flywheels as energy storage systems. The-proposed applications include energy storage for hybrid and electric automobiles, attitude control and energy storage for satellites, and uninterruptible power supplies for hospitals and computer centers. For many years, however, the use of flywheels for space applications was restricted by the total weight of a system employing a metal rotor. With recent technological advances in the manufacturing of composite materials, however, lightweight composite rotors have begun to be proposed for such applications. Flywheels with composite rotors provide much higher power and energy storage capabilities than conventional chemical batteries. However, the failure of a high speed flywheel rotor could be a catastrophic event. For this reason, flywheel rotors are classified by the NASA Fracture Control Requirements Standard as fracture critical parts. Currently, there is no industry standard to certify a composite rotor for safe and reliable operation forth( required lifetime of the flywheel. Technical problems hindering the development of this standard include composite manufacturing inconsistencies, insufficient nondestructive evaluation (NDE) techniques for detecting defects and/or impact damage, lack of standard material test methods for characterizing composite rotor design allowables, and no unified proof (over-spin) test for flight rotors. As part of a flywheel rotor safe-life certification pro-ram funded b the government, a review of the state of the art in composite rotors is in progress. The goal of the review is to provide a clear picture of composite flywheel rotor technologies. The literature review has concentrated on the following topics concerning composites and composite rotors: durability (fatigue) and damage tolerance (safe-life) analysis/test methods, in-service NDE and health monitoring techniques, spin test methods/ procedures, and containment options

  10. Asymptotically safe inflation from quadratic gravity

    CERN Document Server

    Bonanno, Alfio

    2015-01-01

    Asymptotically Safe theories of gravity have recently received much attention. In this work we discuss a class of inflationary models derived from quantum-gravity modification of quadratic gravity according to the induced scaling around the non-Gaussian fixed point at very high energies. It is argued that the presence of a three dimensional ultraviolet critical surface generates operators of non-integer power of the type $R^{2-\\theta/2}$ in the effective Lagrangian, where $\\theta>0$ is a critical exponent. The requirement of a successful inflationary model in agreement with the recent Planck 2015 data puts important constraints on the strenght of this new type of couplings.

    2017-02-28

    To investigate the relationship between substances of abuse and age at motor onset (AMO) in patients with Huntington disease (HD) in a large and diverse patient population. This was a retrospective, observational study of the Enroll-HD database. Participants were determined to belong to 1 of 3 substance abuse groups: (1) tobacco abusers, (2) alcohol abusers, and (3) drug abusers. A group of participants who had never abused substances served as a control group. The average AMO of patients in the substance abuse groups was compared to the control group. The number of CAG repeats was used as a covariate in all analyses. The average difference in AMOs of participants in the tobacco (n = 566), alcohol (n = 374), and drug abuse groups (n = 217) compared to the control group (n = 692) were 2.3 (F1, 1,258 = 33.8, p < 0.0001), 1.0 (F1, 1,066 = 4.2, p = 0.04), and 3.3 (F1, 909 = 29.7, p < 0.0001) years earlier, respectively. In all substance abuse groups, the AMO was lowered to a greater degree in female participants than it was in male participants. Substances of abuse have a strong effect on the AMO in patients with HD. These effects seem to be amplified in women with HD compared to men. These results may provide a safe intervention capable of adding disease-free years to patients with HD. © 2017 American Academy of Neurology.

    Full Text Available Background. Organizing and performing patient transfers in the continuum of care is part of the work of nurses and other staff of a multiprofessional healthcare team. An understanding of discharge practices is needed in order to ultimate patients’ transfers from high technological intensive care units (ICU to general wards. Aim. To describe, as experienced by intensive care and general ward staff, what strategies could be used when organizing patient’s care before, during, and after transfer from intensive care. Method. Interviews of 15 participants were conducted, audio-taped, transcribed verbatim, and analyzed using qualitative content analysis. Results. The results showed that the categories secure, encourage, and collaborate are strategies used in the three phases of the ICU transitional care process. The main category; a safe, interactive rehabilitation process, illustrated how all strategies were characterized by an intention to create and maintain safety during the process. A three-way interaction was described: between staff and patient/families, between team members and involved units, and between patient/family and environment. Discussion/Conclusions. The findings highlight that ICU transitional care implies critical care rehabilitation. Discharge procedures need to be safe and structured and involve collaboration, encouraging support, optimal timing, early mobilization, and a multidiscipline approach.

  17. Implementation of the NANoREG Safe-by-Design approach for different nanomaterial applications

    Micheletti, C.; Roman, M.; Tedesco, E.; Olivato, I.; Benetti, F.

    2017-06-01

    The Safe-by-Design (SbD) concept is already in use in different industrial sectors as an integral part of the innovation process management. However, the adopted approach is often limited to design solutions aiming at hazard reduction. Safety is not always considered during the innovation process, mainly due to the lack of knowledge (e.g. in small and medium companies, SMEs) and the lack of dialogue between actors along the innovation chain. The net result is that safety is considered only at the end of the innovation process at the market authorization phase, with potential loss of time and money. This is especially valid for manufactured nanomaterials (MNM) for which the regulatory context is not completely developed, and the safety knowledge is not readily available. In order to contribute to a sustainable innovation process in the nanotechnology field by maximising both benefits and safety, the NANoREG project developed a Safe Innovation approach, based on two elements: the Safe-by-Design approach which aims at including risk assessment into all innovation stages; and the Regulatory Preparedness, focused on the dialogue with stakeholders along the innovation chain. In this work we present some examples about the implementation in our Laboratory of this approach for different MNM applications, covering different steps of the innovation chain. The case studies include: the feasibility study of a medical device including substances, for topical application; the testing of two potential nanotech solutions for the consolidation of cultural heritage artifacts; the testing of coatings already on the market for other uses, which was tested as food contact materials (FCM) to evaluate the conformity to food applications. These three examples represent a good opportunity to show the importance of NANoREG SbD and Safe Innovation Approach in general, for developing new nanotechnology-based products, also highlighting the crucial role of EU ProSafe project in promoting this

    2013-09-01

    A common commercial marketing segmentation technique is to divide a population into groups based on psychographic characteristics (i.e., attitudes and interests). We used this approach to define segments of female and male college students and examine substance use differences. We administered an online survey to 24,055 students at six colleges in the Southeastern United States (response rate 20.1%, n = 4,840), obtaining complete data from 3,469 participants. We assessed sociodemographics, psychographic factors such as those used by the tobacco industry to define market segments, and substance use (cigarettes, other tobacco products, alcohol, and marijuana). Cluster analysis was conducted among females and males using 15 psychographic measures (sensation seeking, Big Five personality traits, and nine measures adapted from tobacco industry documents), identifying three segments per sex. Safe responsibles were characterized by high levels of agreeableness, conscientiousness, emotional stability, academic achievement, and religious service attendance. Stoic individualists were characterized by low extraversion, sensation seeking, and openness. Thrill-seeking socializers were characterized by high levels of sensation seeking and extraversion. Among females, thrill-seeking socializers were significantly more likely than safe responsibles to have used any substance in the prior 30 days (odds ratio [OR] = 2.04, 95% confidence interval [CI] [1.65, 2.52]; Nagelkerke R 2 = .084). Among males, stoic individualists (OR = 1.50, CI [1.08, 2.08]) and thrill-seeking socializers (OR = 1.53, CI [1.09, 2.13]) were more likely than safe responsibles to have used substances in the past 30 days (Nagelkerke R 2 : .109). Psychographic segmentation can identify young adult subgroups with differing psychographic and substance use profiles and inform health campaigns and messaging targeting youth.

  19. Is propolis safe as an alternative medicine?

    Directory of Open Access Journals (Sweden)

    Maria Graça Miguel

    2011-01-01

    Full Text Available Propolis is a resinous substance produced by honeybees as defense against intruders. It has relevant therapeutic properties that have been used since ancient times. Nowadays, propolis is of increasing importance as a therapeutic, alone or included in many medicines and homeopathic products or in cosmetics. Propolis is produced worldwide and honeybees use the flora surrounding their beehives for its production. Therefore its chemical composition may change according to the flora. The phenolic and volatile fractions of propolis have been revised in the present study, as well as some of the biological properties attributed to this natural product. An alert is given about the need to standardize this product, with quality control. This has already been initiated by some authors, mainly in the propolis from the poplar-type. Only this product can constitute a good complementary and alternative medicine under internationally acceptable quality control.

    The stressful conditions under which nurses work, due in part to the nursing shortage, are among the risk factors that contribute to nurses' abuse of illicit drugs. Nurses differ from the general population in that they work in an environment where they not only have access to controlled substances, but also are exposed to death and dying, the stress of which can increase the risk of drug abuse. However, practicing while impaired places patients' lives at risk and decreases staff morale. Copyright 2010, SLACK Incorporated.

    2011-01-01

    Ground-to-space laser uplinks to Earth–orbiting satellites and deep space probes serve both as a beacon and an uplink command channel for deep space probes and Earth-orbiting satellites. An acquisition and tracking point design to support a high bandwidth downlink from a 20-cm optical terminal on an orbiting Mars spacecraft typically calls for 2.5 kW of 1030-nm uplink optical power in 40 micro-radians divergent beams.2 The NOHD (nominal ocular hazard distance) of the 1030nm uplink is in excess of 2E5 km, approximately half the distance to the moon. Recognizing the possible threat of high power laser uplinks to the flying public and to sensitive Earth-orbiting satellites, JPL developed a three-tiered system at its Optical Communications Telescope Laboratory (OCTL) to ensure safe laser beam propagation through navigational and near-Earth space.

    The present work compiles a review on drinking waterborne outbreaks, with the perspective of production and distribution of microbiologically safe water, during 2000-2014. The outbreaks are categorised in raw water contamination, treatment deficiencies and distribution network failure. The main causes for contamination were: for groundwater, intrusion of animal faeces or wastewater due to heavy rain; in surface water, discharge of wastewater into the water source and increased turbidity and colour; at treatment plants, malfunctioning of the disinfection equipment; and for distribution systems, cross-connections, pipe breaks and wastewater intrusion into the network. Pathogens causing the largest number of affected consumers were Cryptosporidium, norovirus, Giardia, Campylobacter, and rotavirus. The largest number of different pathogens was found for the treatment works and the distribution network. The largest number of affected consumers with gastrointestinal illness was for contamination events from a surface water source, while the largest number of individual events occurred for the distribution network.

  10. Towards Safe Navigation by Formalizing Navigation Rules

    2013-06-01

    Full Text Available One crucial aspect of safe navigation is to obey all navigation regulations applicable, in particular the collision regulations issued by the International Maritime Organization (IMO Colregs. Therefore, decision support systems for navigation need to respect Colregs and this feature should be verifiably correct. We tackle compliancy of navigation regulations from a perspective of software verification. One common approach is to use formal logic, but it requires to bridge a wide gap between navigation concepts and simple logic. We introduce a novel domain specification language based on a spatio-temporal logic that allows us to overcome this gap. We are able to capture complex navigation concepts in an easily comprehensible representation that can direcly be utilized by various bridge systems and that allows for software verification.

  15. Estimated Maximal Safe Dosages of Tumescent Lidocaine

    Science.gov (United States)

    Jeske, Daniel R.

    2016-01-01

    BACKGROUND: Tumescent lidocaine anesthesia consists of subcutaneous injection of relatively large volumes (up to 4 L or more) of dilute lidocaine (≤1 g/L) and epinephrine (≤1 mg/L). Although tumescent lidocaine anesthesia is used for an increasing variety of surgical procedures, the maximum safe dosage is unknown. Our primary aim in this study was to measure serum lidocaine concentrations after subcutaneous administration of tumescent lidocaine with and without liposuction. Our hypotheses were that even with large doses (i.e., >30 mg/kg), serum lidocaine concentrations would be below levels associated with mild toxicity and that the concentration-time profile would be lower after liposuction than without liposuction. METHODS: Volunteers participated in 1 to 2 infiltration studies without liposuction and then one study with tumescent liposuction totally by local anesthesia. Serum lidocaine concentrations were measured at 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, and 24 hours after each tumescent lidocaine infiltration. Area under the curve (AUC∞) of the serum lidocaine concentration-time profiles and peak serum lidocaine concentrations (Cmax) were determined with and without liposuction. For any given milligram per kilogram dosage, the probability that Cmax >6 μg/mL, the threshold for mild lidocaine toxicity was estimated using tolerance interval analysis. RESULTS: In 41 tumescent infiltration procedures among 14 volunteer subjects, tumescent lidocaine dosages ranged from 19.2 to 52 mg/kg. Measured serum lidocaine concentrations were all lidocaine toxicity without liposuction at a dose of 28 mg/kg and with liposuction at a dose of 45 mg/kg was ≤1 per 2000. CONCLUSIONS: Preliminary estimates for maximum safe dosages of tumescent lidocaine are 28 mg/kg without liposuction and 45 mg/kg with liposuction. As a result of delayed systemic absorption, these dosages yield serum lidocaine concentrations below levels associated with mild toxicity and are a nonsignificant

  16. Safe and Secure Services Based on NGN

    Science.gov (United States)

    Fukazawa, Tomoo; Nisase, Takemi; Kawashima, Masahisa; Hariu, Takeo; Oshima, Yoshihito

    Next Generation Network (NGN), which has been undergoing standardization as it has developed, is expected to create new services that converge the fixed and mobile networks. This paper introduces the basic requirements for NGN in terms of security and explains the standardization activities, in particular, the requirements for the security function described in Y.2701 discussed in ITU-T SG-13. In addition to the basic NGN security function, requirements for NGN authentication are also described from three aspects: security, deployability, and service. As examples of authentication implementation, three profiles-namely, fixed, nomadic, and mobile-are defined in this paper. That is, the “fixed profile” is typically for fixed-line subscribers, the “nomadic profile” basically utilizes WiFi access points, and the “mobile profile” provides ideal NGN mobility for mobile subscribers. All three of these profiles satisfy the requirements from security aspects. The three profiles are compared from the viewpoint of requirements for deployability and service. After showing that none of the three profiles can fulfill all of the requirements, we propose that multiple profiles should be used by NGN providers. As service and application examples, two promising NGN applications are proposed. The first is a strong authentication mechanism that makes Web applications more safe and secure even against password theft. It is based on NGN ID federation function. The second provides an easy peer-to-peer broadband virtual private network service aimed at safe and secure communication for personal/SOHO (small office, home office) users, based on NGN SIP (session initiation protocol) session control.

    2016-06-01

    Parental and peer influences on adolescent substance use have been well demonstrated. However, limited research has examined how parental and peer influences vary across school contexts. This study used a multilevel approach to examine the effects of school substance use norms and school racial composition in predicting adolescent substance use (a composite measure of alcohol, tobacco, and marijuana use) and in moderating parental and peer influences on adolescent substance use. A total of 14,346 adolescents from 34 schools in a mid-western county completed surveys electronically at school. Analyses were conducted using hierarchical linear modeling. Results indicated that school-level disapproval against substance use and percentage of minority students at school were negatively associated with adolescent substance use. School-level disapproval moderated the association between peer substance use and adolescent substance use, with the association being stronger when school-level disapproval was lower. School racial composition moderated the influence of parental disapproval and peer substance use on adolescent substance use. Specifically, both the association between parental disapproval and adolescent substance use and the association between peer substance use and adolescent substance use were weaker for adolescents who attended schools with higher percentages of minority students. Findings highlighted the importance of considering the role of school contexts, in conjunction with parental and peer influences, in understanding adolescent substance use. © Society for Community Research and Action 2016.

    This paper is a report of a conceptual analysis of women-controlled safe sex. Women bear disproportionate burdens from sexually related health compromising outcomes. Imbalanced societal gender and power positions contribute to high morbidities. The expression, women-controlled safe sex, aims to empower women to gain control of their sexual lives. Few researchers focus on contextualized socio-cultural definitions of sexual safety among women. The sample included scientific literature from Scopus, CINAHL, PubMed, PsychINFO and Sociological Abstracts. Papers were published 2000-2010. Critical analyses of literature about women-controlled safe sex were performed in May 2011 using Rodgers' evolutionary concept analysis methods. The search focused on social and cultural influences on sexual practices aimed at increasing women's control over their sexual safety. The analysis uncovered five attributes of women-controlled safe sex: technology; access to choices; women at-risk; 'condom migration' panic; and communication. Three antecedents included: male partner influence; body awareness; and self-efficacy. Consequences were categorized as positive or negative. Nine surrogate terms included: empowerment; gender power; female-controlled sexual barrier method; microbicides; diaphragm; sexual negotiation and communication; female condom; women-initiated disease transmission prevention; and spermicides. Finally, a consensus definition was identified: a socio-culturally influenced multi-level process for initiating sexual safety by women deemed at-risk for sexually related dangers, usually sexually transmitted infections and/or HIV/AIDS. This concept analysis described current significance, uses, and applications of women-controlled safe sex in the scientific literature. The authors clarified its limited nature and conclude that additional conceptual refinement in nursing is necessary to influence women's health. © 2011 Blackwell Publishing Ltd.

    In respect of demographic change, the number of older patients with substance abuse and addiction is on the raise. In this review we present important clinical and therapeutic aspects of substance abuse and addiction in the elderly and focus on alcohol, benzodiazepines and opioids. Daily and risky alcohol consumption is common among older people. They also have an increased risk getting alcohol-related complications. For early detection, laboratory parameters and questionnaires such as the AUDIT-C are suitable. Therapeutically brief interventions have been proved successful. Also, abuse of benzodiazepines, especially low-dose addiction, is widespread among older persons, although often overlooked, and patients often do not recognize their addiction. The physician has to know the correct indication, adequate dosage and pharmacological interactions. A slow-dose reduction is recommended in case of addiction. Thanks to opioid substitution therapy, patients with an opioidaddiction can reach a higher age. Age influences the effects of the substitute, which may require an adjustment of the dosage. Treatment of elderly patients should be based on their needs and resources and is usually very effective.

    An optimal biochemical marker for addiction would be some easily traced molecules in body specimens, which indicates indulgent addictive behaviors, or susceptibility to certain addictive stimuli. In this chapter, we discussed existing literature about possible biomarkers, and classified them into three categories: origin forms and metabolites of substances, markers from biochemical responses to certain addiction, and genetic and epigenetic biomarkers suggesting susceptibility to addiction. In every category, we examined studies concerning certain type of addiction one by one, with focuses mainly on opiates, psychostimulants, and pathological gambling. Several promising molecules were highlighted, including those of neurotrophic factors, inflammatory factors, and indicators of vascular injury, and genetic and epigenetic biomarkers such as serum miRNAs. DNA methylation signatures and signal nucleotide polymorphism of candidate gene underlying the addiction.

    We examined openly shared substance-related tweets to estimate prevalent sentiment around substance use and identify popular substance use activities. Additionally, we investigated associations between substance-related tweets and business characteristics and demographics at the zip code level. A total of 79,848,992 tweets were collected from 48 states in the continental United States from April 2015-March 2016 through the Twitter API, of which 688,757 were identified as being related to substance use. We implemented a machine learning algorithm (maximum entropy text classifier) to estimate sentiment score for each tweet. Zip code level summaries of substance use tweets were created and merged with the 2013 Zip Code Business Patterns and 2010 US Census Data. Quality control analyses with a random subset of tweets yielded excellent agreement rates between computer generated and manually generated labels: 97%, 88%, 86%, 75% for underage engagement in substance use, alcohol, drug, and smoking tweets, respectively. Overall, 34.1% of all substance-related tweets were classified as happy. Alcohol was the most frequently tweeted substance, followed by marijuana. Regression results suggested more convenience stores in a zip code were associated with higher percentages of tweets about alcohol. Larger zip code population size and higher percentages of African Americans and Hispanics were associated with fewer tweets about substance use and underage engagement. Zip code economic disadvantage was associated with fewer alcohol tweets but more drug tweets. The patterns in substance use mentions on Twitter differ by zip code economic and demographic characteristics. Online discussions have great potential to glorify and normalize risky behaviors. Health promotion and underage substance prevention efforts may include interactive social media campaigns to counter the social modeling of risky behaviors.

    Substance use disorders are major contributors to excess mortality among individuals with attention deficit hyperactivity disorder (ADHD), yet associations between pharmacological ADHD treatment and substance-related problems remain unclear. This study investigated concurrent and long-term associations between ADHD medication treatment and substance-related events. The authors analyzed 2005-2014 commercial health care claims from 2,993,887 (47.2% female) adolescent and adult ADHD patients. Within-individual analyses compared the risk of substance-related events (i.e., emergency department visits related to substance use disorders) during months in which patients received prescribed stimulant medication or atomoxetine relative to the risk during months in which they did not. In adjusted within-individual comparisons, relative to periods in which patients did not receive ADHD medication, male patients had 35% lower odds of concurrent substance-related events when receiving medication (odds ratio=0.65, 95% CI=0.64-0.67), and female patients had 31% lower odds of concurrent substance-related events (odds ratio=0.69, 95% CI=0.67-0.71). Moreover, male patients had 19% lower odds of substance-related events 2 years after medication periods (odds ratio=0.81, 95% CI=0.78-0.85), and female patients had 14% lower odds of substance-related events 2 years after medication periods (odds ratio=0.86, 95% CI= 0.82-0.91). Sensitivity analyses supported most findings but were less consistent for long-term associations among women. These results provide evidence that receiving ADHD medication is unlikely to be associated with greater risk of substance-related problems in adolescence or adulthood. Rather, medication was associated with lower concurrent risk of substance-related events and, at least among men, lower long-term risk of future substance-related events.

    Gregg, Lynsey; Barrowclough, Christine; Haddock, Gillian

    2007-05-01

    Around half of all patients with schizophrenia are thought to abuse drugs or alcohol and there is good evidence to suggest that they have poorer outcomes than their non substance using counterparts. However, despite more than twenty years of research there is still no consensus on the aetiology of increased rates of substance use in people with psychosis. There is a clear need to understand the reasons for such high rates of substance use if treatments designed to help patients abstain from substance use are to be successful. This paper provides an update of the literature examining the reasons for substance use by people with psychosis, and includes a comprehensive review of the self report literature. The main theories as to why people with psychosis use substances are presented. There is evidence to suggest that cannabis may have a causal role in the development of psychopathology but not for other substances. The self report literature provides support for an 'alleviation of dysphoria' model of substance use but there is little empirical support for the self medication hypothesis, or for common factor models and bidirectional models of comorbidity. It is likely that there are multiple risk factors involved in substance use in psychosis and more work to develop and test multiple risk factor models is required.

    2011-10-01

    Incarcerated women have high rates of substance abuse problems and trauma. A variety of variables may influence whether these women seek help or are referred for substance abuse problems. This study reports an exploratory project on service utilization among incarcerated substance-dependent women (N = 40) in southeastern Idaho. Using self-report and interview tools, most participants reported some substance abuse treatment history, although extent and types of treatment varied. Most of the women also reported some type of childhood abuse. Age, income, and consequences of alcohol and other drug use related positively to substance abuse treatment. However, severity of childhood sexual abuse and current trauma symptoms were negatively correlated with substance abuse treatment episodes. These women may use substances to cope with childhood trauma or may not perceive the substance abuse system as responsive to their co-occurring trauma symptoms. Copyright © 2011 Elsevier Inc.

    Full Text Available Abstract Background Safe Psoriasis Control (SPC is an important comprehensive measure that is validated for the assessment of benefit:risk of psoriasis treatments, combining efficacy, quality of life, and safety measures. The objective of this analysis was to assess the benefit:risk of efalizumab, a novel biologic agent indicated for the treatment of moderate-to-severe plaque psoriasis, by applying the SPC to data from randomized, placebo-controlled clinical studies of efalizumab. Methods SPC was applied to week 12 data from four placebo-controlled, Phase III studies: three retrospective and one prospective, the latter including a cohort of "high-need" patients for whom existing therapies were inadequate or unsuitable. Results In the retrospective analysis, 39.4% of patients achieved SPC after 12 weeks of treatment with efalizumab, compared with 10.4% for placebo. In the prospective analysis, 34.3% of patients achieved SPC after 12 weeks of treatment with efalizumab, compared with 7.3% on placebo. Among high-need patients, 33.0% achieved SPC, compared with 3.4% on placebo. Conclusion Efalizumab has a favorable benefit:risk profile using the comprehensive outcome measure SPC.

Conceptual design of fluid system 5. Conceptual design of reactor vessel assembly and primary components 6. Performance analyses and safety analyses. Installation of two ISIRs with total thermal power of 600MWt and efficiency of 21% is capable of generating shaft power of 126,000kW which is sufficient to power a container ship of 8,000TEU with 30knot cruise speed. Larger and speedier ship can be considered by installing 4 ISIRs. Even though the ISIR was developed for ship propulsion, it can be used also for a multi-purpose nuclear power plant for electricity generation, local heating, or seawater desalination by mounting on a movable floating barge.

    2017-08-03

    CarbonSAFE Illinois is a a Feasibility study to develop an established geologic storage complex in Macon County, Illinois, for commercial-scale storage of industrially sourced CO2. Feasibility activities are focused on the Mt. Simon Storage Complex; a step-out well will be drilled near existing storage sites (i.e., the Midwest Geological Sequestration Consortium’s Illinois Basin – Decatur Project and the Illinois Industrial Carbon Capture and Storage Project) to further establish commercial viability of this complex and to evaluate EOR potential in a co-located oil-field trend. The Archer Daniels Midland facility (ethanol plant), City Water, Light, and Power in Springfield, Illinois (coal-fired power station), and other regional industries are potential sources of anthropogenic CO2 for storage at this complex. Site feasibility will be evaluated through drilling results, static and dynamic modeling, and quantitative risk assessment. Both studies will entail stakeholder engagement, consideration of infrastructure requirements, existing policy, and business models. Project data will help calibrate the National Risk Assessment Partnership (NRAP) Toolkit to better understand the risks of commercial-scale carbon storage.

    A Post-Fukushima perspective This paper lists and briefly describes challenges and issues at stake that used Fuel Management will be facing at existing spent fuel p001 at reactors in operation or permanently shutdown in the aftermath of Fukushima and upcoming stress tests and beyond. It is also an attempt to jet from the perspective of AREVA, existing and proven products and services going along risk reduction strategies that may be of value to adequate protection that appropriately balances defence-in-depth and risk considerations as far as Used Fuel Management is considered and this from the very starting point namely the unloading of used fuel at SFP. Over the past decades, AREVA never stops enhancing used fuel recycling performances and developing innovative solutions to respond to plant, utility or country related constraints. This will be illustrated through a few business cases that best describe the various proven solutions and implemented contractual schemes for the safe and optimized management of used fuel today.

    Practice regarding the use of post operative drains after simple mastectomy varies widely. This project aimed to establish if not using a drain lead to an increase in post-operative seroma formation or other complications. Women undergoing simple mastectomy ± sentinel node biopsy were included. Patients were allocated to drain/no drain group via operating surgeon. Data was collected retrospectively from computer based records. Drain output, length of stay, seroma formation and volume and post-operative complications were recorded. There were 39 patients in the drain group and 24 patients in the no drain group. Patients did not differ significantly in terms of age, BMI or specimen weight. Seroma was more prevalent in the no drain group (62 v 83%) and required more clinic attendances for aspiration with larger volumes drained (360 vs 725 ml, p = 0.0096). There was no difference in overall complication rate. There did not appear to be a correlation between seroma formation and age, BMI or mastectomy weight. The use of a drain after simple mastectomy may confer lower rates of seroma formation as well as lower overall volumes. Therefore drainless mastectomy appears to be safe but may require more post-operative intervention.

    Full Text Available Programming systems incorporating aspects of functional programming, e.g., higher-order functions, are becoming increasingly popular for large-scale distributed programming. New frameworks such as Apache Spark leverage functional techniques to provide high-level, declarative APIs for in-memory data analytics, often outperforming traditional "big data" frameworks like Hadoop MapReduce. However, widely-used programming models remain rather ad-hoc; aspects such as implementation trade-offs, static typing, and semantics are not yet well-understood. We present a new asynchronous programming model that has at its core several principles facilitating functional processing of distributed data. The emphasis of our model is on simplicity, performance, and expressiveness. The primary means of communication is by passing functions (closures to distributed, immutable data. To ensure safe and efficient distribution of closures, our model leverages both syntactic and type-based restrictions. We report on a prototype implementation in Scala. Finally, we present preliminary experimental results evaluating the performance impact of a static, type-based optimization of serialization.

    2012-01-01

    How to Observe the Sun Safely, Second Edition gives all the basic information and advice the amateur astronomer needs to get started in observing our own ever-fascinating star. Unlike many other astronomical objects, you do not need a large telescope or expensive equipment to observe the Sun. And it is possible to take excellent pictures of the Sun with today's low-cost digital cameras! This book surveys what is visible on the Sun and then describes how to record solar features and measure solar activity levels. There is also an account of how to use H-alpha and Calcium-K filters to observe and record prominences and other features of the solar chromosphere, the Sun's inner atmosphere. Because we are just entering a period of high activity on the Sun, following a long, quiet period, this is a great time to get involved with solar observing. Still emphasizing safety first, this Second Edition reflects recent and exciting advances in solar observing equipment. Chapters 6 through 8 have been completely revised ...

    To review our experience from a high volume stone center with a focus on efficacy, safety, and renal function. Stones requiring percutaneous nephrolithotomy (PCNL) in patients with solitary kidneys can pose significant anxiety to the urologist. Limited data are available in published reports in this setting. A comprehensive retrospective review of medical records was performed on patients who underwent PCNL and had a solitary kidney or a single functioning renal unit. Data were collected on patient demographics, stone burden, outcomes, complications, and renal function. Of 378 PCNLs performed between January 2003 and September 2011, 22 were performed in 17 patients with a single functioning kidney. Three procedures were performed in a transplanted kidney. In those with solitary calculus, the longest mean length and stone surface area were 37 mm and 825 mm(2), respectively. Stone-free rate was 59%. Auxiliary procedures were required in 6 cases, resulting in a stone-free rate of 77%. Median inpatient stay was 4 days. Serum creatinine values improved from 144 to 126 umol/L before and after the procedure and mean estimated glomerular filtration rate improved similarly from 51 to 59 mls/minute, respectively. Blood transfusion was required in 1 patient, sepsis developed in 3, and 2 patients required a stent for obstruction. PCNL in solitary kidneys is safe with an acceptable complication rate if performed in a high volume center. Outcomes are good, although auxiliary procedures may be necessary. Renal function remains stable or improves after procedure. Copyright © 2013 Elsevier Inc. All rights reserved.

    In order to compliment the inadequate health facilities in the rural areas in Nigeria, nongovernmental organisations provide adhoc outreach health camps that offer treatment in various medical specialties including surgery. Rural outreach health camps. To evaluate the safety of thyroidectomy under local anaesthesia at rural outreach setting with inadequate facilities for general anaesthesia. This was a prospective descriptive study of 33 consecutive cases of thyroidectomy performed using field block with 1% lignocaine and adrenaline 1: 200,000 dilution during two free medical outreaches that held at Jos, Nigeria in March and October 2005 respectively, lasting two weeks each. A total of 33 primary thyroid operations were performed consisting of 30 subtotal thyroidectomies (91%), 2 lobectomies (6%) and one total thyroidectomy (3%), The patients were aged between 23 and 62 years with a mean age of 45.8 years. There were 3 males and 30 females with a male: female ratio of 1:10. There was no mortality but morbidity was 2/33 (6%) Two complications were recorded in 2 patients and were superficial surgical site infection (3%) and reactionary haemorrhage (3%). We conclude that thyroidectomy under local anaesthesia is a safe procedure in experienced hands at rural settings with inadequate facilities for general anaesthesia.

    Full Text Available Background: the guarantee of sporting success lies in the appropriate functioning of the musculoskeletal system, given that its vulnerability hinders the performance of each athlete. Being timely is critical to provide safe care to the affections of knee; late diagnosis in this system may lead to the development of complications and hinder sport practice. Objective: to characterize knee injuries in athletes of the sport system in the province of Cienfuegos.Methods: an observational, quantitative and qualitative, longitudinal and retrospective study was conducted. It included 104 athletes who attended the Traumatology Consultation from 2009 to 2011, presenting different types of knee injuries in various stages of training. Variables such as age, sex, sport, site of injury, stage of training, kilocalories consumed, type of training, quality of equipment and diagnosis were analyzed. The procedure used consists of a comprehensive review of case notes and medical records of all patients that attended consultation during the period analyzed, from which the necessary data was collected. Interviews with coaches and technical staff were carried out as well. Results: knee injuries occur in all ages of athletes, with a slight predominance of males. Highest frequencies are those of the ligament and meniscus, with the highest incidence in athletics, volleyball and judo. Conservative treatment predominated.Conclusions: knee injuries require a timely treatment in order to achieve athlete's success and safety.

  3. Surgery aboard ship: is it safe?

    Fontana, M; Lucha, P; Snyder, M; Liston, W

    1999-09-01

    A retrospective review was performed on 684 surgical procedures done aboard U.S. Atlantic Fleet ships during a 3-year period from 1994 to 1996. These procedures were compared with similar procedures performed at the Naval Medical Center in Portsmouth, Virginia. Morbidity and mortality rates were calculated and compared. A very low morbidity rate (0.43%) was reported for surgical procedures performed while deployed compared with 1.69% for procedures at the Naval Medical Center. One mortality was reported. These extremely low rates are felt to be attributable to multiple causes, including a highly selected, healthy patient population, performance of only low-risk procedures, early presentation of surgical problems, and early medical evacuation of patients with complex medical and surgical problems. We feel that elective surgical procedures such as vasectomy, circumcision, inguinal hernia repair, and hemorrhoidectomy can be performed safely aboard ship. This would increase the training opportunity for all members of the medical department and at the same time decrease the costs and risks associated with medical evacuation.

  4. Aluminum vaccine adjuvants: are they safe?

    Science.gov (United States)

    Tomljenovic, L; Shaw, C A

    2011-01-01

    Aluminum is an experimentally demonstrated neurotoxin and the most commonly used vaccine adjuvant. Despite almost 90 years of widespread use of aluminum adjuvants, medical science's understanding about their mechanisms of action is still remarkably poor. There is also a concerning scarcity of data on toxicology and pharmacokinetics of these compounds. In spite of this, the notion that aluminum in vaccines is safe appears to be widely accepted. Experimental research, however, clearly shows that aluminum adjuvants have a potential to induce serious immunological disorders in humans. In particular, aluminum in adjuvant form carries a risk for autoimmunity, long-term brain inflammation and associated neurological complications and may thus have profound and widespread adverse health consequences. In our opinion, the possibility that vaccine benefits may have been overrated and the risk of potential adverse effects underestimated, has not been rigorously evaluated in the medical and scientific community. We hope that the present paper will provide a framework for a much needed and long overdue assessment of this highly contentious medical issue.

    2000-09-01

    This study was undertaken to assess the safety of various acellular vaccines (ACV) TripAcel, PacMarieux--Pasteur Merieux, Infanrix-SKB, Acel-P-Lederle and DTaP-SSI in 355 children, aged 7 weeks to 7 years, dismissed from immunization against pertussis with a whole-cell vaccine. All ACV contained varying concentrations of pertussis toxin; some vaccines contained filamentous hemagglutinin, pertactin and/or agglutinogens. The indication of using ACV were adverse effects following immunization (AEFI) after wP vaccine (n = 29) and others reasons, mostly underlying perinatal and CNS pathology (n = 277). The 564 doses of ACV were given in 4 to 1 doses. Reaction forms and clinical follow-up were uniform throughout the study. Serious AEFI cases were not observed not only among children with CNS damage, but also in children with previous AEFI after DTwP vaccine. All ACV recipients consistently reported low rates of reactions in the 48 hours following immunization. We concluded that all investigated ACV were safe and well tolerated even in the group of high-risk children.

  6. Topological characterization of safe coordinated vehicle motions

    Energy Technology Data Exchange (ETDEWEB)

    MILGRAM.R. JAMES; KAUFMAN,STEPHEN G.

    2000-04-03

    This paper characterizes the homotopy properties and the global topology of the space of positions of vehicles which are constrained to travel without intersecting on a network of paths. The space is determined by the number of vehicles and the network. Paths in the space correspond to simultaneous non-intersecting motions of all vehicles. The authors therefore focus on computing the homotopy type of the space, and show how to do so in the general case. Understanding the homotopy type of the space is the central issue in controlling the vehicles, as it gives a complete description of the distinct ways that vehicles may move safely on the network. The authors exhibit graphs, products of graphs, and amalgamations of products of graphs that are homotopy equivalent to the full configuration space, and are far simpler than might be expected. The results indicate how a control system for such a network of vehicles (such as a fleet of automatically guided vehicles guided by wires buried in a factory floor) may be implemented.

    2016-01-01

    Following a recent article about safe cycling (see here), the Bulletin received a request for more details on the type of accidents that are reported.   An analysis of the 38 accidents involving bicycles reported this year up to the end of August reveals that the most common single cause of accidents is slippery surfaces: ice, snow, water and gravel, so the message here is to take extra care, particularly when cycling in bad weather. The second item on the list is obstacles of various kinds: collisions with kerbs, potholes and even the transition from roads to cycle paths. The lesson here is to pay close attention to the surface you’re cycling over, and if you do spot a pothole, even if it does not lead to an accident, report it so that it can be repaired. It’s also worth remembering that you’re more likely to avoid coming off your bike if you keep your hands on the handlebars. The third highest cause is collisions with other vehicles, and here there are lessons for ...

    2013-04-01

    The purpose of the current study was to evaluate possible overlapping substance abuse and internet addiction in a large, uniformly sampled population, ranging in age from 13 to 18 years. Participants (N=73,238) in the current study were drawn from the 6th Korea Youth Risk Behavior Web-based Survey (KYRBWS-V) for students from 400 middle schools and 400 high schools in 16 cities within South Korea. Of adolescent internet users, 85.2% were general users (GU), 11.9% were users with potential risk for internet addiction (PR), and 3.0% were users with high risk for internet addiction (HR). There was a difference in the number of students with alcohol drinking among the GU, PR, and HR groups (20.8% vs 23.1% vs 27.4%). There was a difference in the number of students who smoked among the GS, PR, and HR groups (11.7% vs 13.5% vs 20.4%). There was a difference in the number of students with drug use among the GU, PR, and HR groups (1.7% vs 2.0% vs 6.5%). After adjusting for sex, age, stress, depressed mood, and suicidal ideation, smoking may predict a high risk for internet addiction (OR=1.203, p=0.004). In addition, drug use may predict a high risk for internet addiction (OR=2.591, pinternet addiction have vulnerability for addictive behaviors, co-morbid substance abuse should be evaluated and, if found, treated in adolescents with internet addiction.

    2015-01-01

    Nursing students practicing in healthcare settings may increase risks to consumers, if impaired by drugs and/or alcohol, and are incapable of practicing safely. Several agencies implemented educational/professional policies, designed to protect healthcare consumers from risks. Policies addressing impaired nursing students vary among these agencies, and no nationally implemented policy exists for the treatment of impaired nursing student practice in the United States. This scoping study synthesizes substance abuse policy among nursing students, guided by the research question: What professional and state policies exist to address substance abuse among U.S. nursing students? The broader term, substance abuse, was used because alcohol-specific policies were not identified. Evidence was drawn from several policy documents identified through electronic sources that include national nursing organizations (NNOs) and nurse practice acts (NPAs) and rules. A comparative analysis was conducted on the identified policies to determine similarities and differences at the national and state levels and between national and state levels. Four NNO policies, 50 U.S. states, District of Columbia, and two U.S. territories' NPAs were selected for review based on selection criteria. Six areas were identified in NNO policies, and four were identified in NPAs that addressed chemically impaired nursing students. This review of current policy provided evidence that identifies and describes areas of concern. Impaired nursing practice, which includes nursing students, remains a major issue, complicated by the inconsistencies noted particularly within the reviewed NPAs. Knowledge gained from this review will be used to guide future research and subsequent state policy development.

    The objective of this study was to evaluate a specialised service designed to improve parenting capacity, child safety and family functioning in the context of parental mental health, drug and alcohol and child protection concerns. Client data was collected over a period of 3 years and 3 months, including demographic characteristics, service usage, presenting issues and pre and post revised North Carolina Family Assessment Scale (NCFAS-G) scores. A significant improvement between intake and discharge occurred on the majority of the 58 NCFAS-G subscale items (32/58). In particular, most significant change occurred in the domains 'family safety' (p < 0.001) and 'family interactions' (p < 0.001). Specialised programs can assist families with child safety concerns suffering from mental health and/or drug and alcohol problems. © The Royal Australian and New Zealand College of Psychiatrists 2016.

  12. Is there any additional benefit of contrast-enhanced CT as part of routine PET/CT protocols for the differentiation of suspicious incidental gastrointestinal 2-deoxy-{sup 18}F-FDG uptake?

    Suspicious incidental gastrointestinal FDG uptake during positron-emission tomography/computed tomography (PET/CT) examinations can be caused by different diseases, including malignancies. However, differentiation with PET alone is difficult. The aim of this study was to investigate the potential of PET alone, contrast-enhanced CT (ceCT), and low-dose CT (ldCT) in routine PET/CT protocols for differentiation of incidental gastrointestinal lesions. Sixty patients with incidental gastrointestinal lesions who underwent a routine PET/CT protocol with ldCT and ceCT were retrospectively analysed. The PET lesions were evaluated regarding their FDG uptake patterns and the standard uptake value. The anatomical correlates in both CT protocols were compared in regard to the correct lesion classification with the reference standard endoscopy. Sixty-two lesions were found in 60 patients (17 malignant, 10 premalignant, 5 benign, 13 inflammatory, 17 physiological). The differentiation of the FDG uptake patterns did not enable reliable lesion classification. The positive predictive value for pathology was 0.81 for ceCT in PET/CT and 0.70 for ldCT. Malignancies were detected in 100% of the patients by ceCT vs. 29.4% by ldCT. The false negative rate of ceCT for all pathologies was 31.1%, vs. 68.9% for ldCT. False positive results (17/62) could not be excluded sufficiently by either CT protocol. PET/ceCT protocols provide additional benefit especially in detecting gastrointestinal malignancies as a cause of suspicious incidental gastrointestinal FDG uptake. However, since follow-up endoscopy cannot be forgone due to the considerable false negative rate even with ceCT, the addition of ceCT to a routine PET/ldCT protocol cannot be recommended for this purpose.

    2017-01-01

    In this article, we describe the role of "clinical scenario" information to assure the safety of interoperable systems, as well as the system's ability to deliver the requisite clinical functionality to improve clinical care. Described are methods and rationale for capturing the clinical needs, workflow, hazards, and device interactions in the clinical environment. Key user (clinician and clinical engineer) needs and system requirements can be derived from this information, therefore, improving the communication from clinicians to medical device and information technology system developers. This methodology is intended to assist the health care community, including researchers, standards developers, regulators, and manufacturers, by providing clinical definition to support requirements in the systems engineering process, particularly those focusing on development of Integrated Clinical Environments described in standard ASTM F2761. Our focus is on identifying and documenting relevant interactions and medical device capabilities within the system using a documentation tool called medical device interface data sheets and mitigating hazardous situations related to workflow, product usability, data integration, and the lack of effective medical device-health information technology system integration to achieve safe interoperability. Portions of the analysis of a clinical scenario for a "patient-controlled analgesia safety interlock" are provided to illustrate the method. Collecting better clinical adverse event information and proposed solutions can help identify opportunities to improve current device capabilities and interoperability and support a learning health system to improve health care delivery. Developing and analyzing clinical scenarios are the first steps in creating solutions to address vexing patient safety problems and enable clinical innovation.

    2005-03-01

    Substance abuse is among one of the major problems plaguing our society. It has come to the attention of several healthcare professionals that a communication gap exists between themselves and substance abusers. Most of the time the substance abusers are only familiar with the slang terms of abused substances, a terminology that medical professionals are usually unaware of. This paper is an attempt to close that communication gap, allowing health care professionals to understand the slang terminology that their patients use, thus enabling them to make appropriate treatment decisions. In addition, the article presents some key features (including active ingredient, pharmacological classification, medical use, abuse form, usage method, combinations used, effects sought, long-term possible effects, and detectability in urine) of the most commonly abused substances.

    Riggs, Nathaniel R

    2015-06-01

    Several preventive interventions have demonstrated efficacy in reducing substance use. However, opportunities exist to further improve prevention approaches. The application of recent advances in developmental neuroscience can inform the design, implementation, and evaluation of substance use prevention programs. This paper first briefly describes the developmental integration of the prefrontal cortex with emotion and motivation centers of the brain, and the implications of this process for substance use vulnerability. Discussed next are specific examples of how developmental neuroscience can inform prevention timing, development, and evaluation. Contextual considerations are then suggested including a critical role for schools in substance misuse prevention. Finally, current theoretical and methodological challenges to the translation of developmental neuroscience to substance use prevention are discussed.

    The Swedish PIUS reactor and the German-American small modular high-temperature gas-cooled reactor are inherently safe-that is, their safety relies not upon intervention of humans or of electromechanical devices but on immutable principles of physics and chemistry. A second nuclear era may require commercialization and deployment of such inherently safe reactors, even though existing light-water reactors appear to be as safe as other well-accepted sources of central electricity, particularly hydroelectric dams.

    Safe-to-mate testing is a common hardware safety practice where impedance measurements are made on unpowered hardware to verify isolation, continuity, or impedance between pins of an interface connector. A computer-based instrumentation solution has been developed to resolve issues. The ASTM is connected to the circuit under test, and can then quickly, safely, and reliably safe-to-mate the entire connector, or even multiple connectors, at the same time.

    The terms "Safe innovation" and "Safe(r)-by-design" are currently popular in the field of nanotechnology. These terms are used to describe approaches that advocate the consideration of safety aspects already at an early stage of the innovation process of (nano)materials and nanoenabled products. Here, we investigate the possibilities of considering safety aspects during various stages of the innovation process of graphene, outlining what information is already available for assessing potential hazard, exposure, and risks. In addition, we recommend further steps to be taken by various stakeholders to promote the safe production and safe use of graphene.

  14. Fire-safe polymers and polymer composites

    Science.gov (United States)

    Zhang, Huiqing

    The intrinsic relationships between polymer structure, composition and fire behavior have been explored to develop new fire-safe polymeric materials. Different experimental techniques, especially three milligram-scale methods---pyrolysis-combustion flow calorimetry (PCFC), simultaneous thermal analysis (STA) and pyrolysis GC/MS---have been combined to fully characterize the thermal decomposition and flammability of polymers and polymer composites. Thermal stability, mass loss rate, char yield and properties of decomposition volatiles were found to be the most important parameters in determining polymer flammability. Most polymers decompose by either an unzipping or a random chain scission mechanism with an endothermic decomposition of 100--900 J/g. Aromatic or heteroaromatic rings, conjugated double or triple bonds and heteroatoms such as halogens, N, O, S, P and Si are the basic structural units for fire-resistant polymers. The flammability of polymers can also be successfully estimated by combining pyrolysis GC/MS results or chemical structures with TGA results. The thermal decomposition and flammability of two groups of inherently fire-resistant polymers---poly(hydroxyamide) (PHA) and its derivatives, and bisphenol C (BPC II) polyarylates---have been systematically studied. PHA and most of its derivatives have extremely low heat release rates and very high char yields upon combustion. PHA and its halogen derivatives can completely cyclize into quasi-polybenzoxazole (PBO) structures at low temperatures. However, the methoxy and phosphate derivatives show a very different behavior during decomposition and combustion. Molecular modeling shows that the formation of an enol intermediate is the rate-determining step in the thermal cyclization of PHA. BPC II-polyarylate is another extremely flame-resistant polymer. It can be used as an efficient flame-retardant agent in copolymers and blends. From PCFC results, the total heat of combustion of these copolymers or blends

    Full Text Available Abstract Background The theory and practice of safety promotion has traditionally focused on the safety of individuals. This study also includes systems, environments, and organizations. Safety promotion programmes are designed to support community health initiatives taking a bottom-up approach. This is a long-term and complex process. The aim of this study was to try to empirically identify factors that promote sustainability in the structures of programmes that are managed and coordinated by the local government. Methods Four focus group sessions with local government politicians and administrators in designated Safe Communities were conducted and analyzed using qualitative content analysis. Results Collaboration was found to be the basis for sustainability. Networks, enabling municipalities to exchange ideas, were reported to positively influence the programmes. Personal contacts rather than organizations themselves, determine whether collaboration is sustained. Participants reported an increase in cross-disciplinary collaboration among staff categories. Administrators and politicians were reported to collaborate well, which was perceived to speed up decision-making and thus to facilitate the programme work. Support from the politicians and the county council was seen as a prerequisite. Participants reported an increased willingness to share information between units, which, in their view, supports sustainability. A structure in which all local authorities' offices were located in close proximity to one another was considered to support collaboration. Appointing a public health coordinator responsible for the programme was seen as a way to strengthen the relational resources of the programme. Conclusion With a public health coordinator, the 'external' negotiating power was concentrated in one person. Also, the 'internal' programme strength increased when the coordination was based on a bureaucratic function rather than on one individual

    2018-02-01

    Full Text Available Context: The care of the ozone layer is an activity that contributes to the planet's environmental stability. For this reason, the Montreal Protocol is created to control the emission of substances that deplete the ozone layer and reduce its production from an organizational point of view. However, it is also necessary to have control of those that are already circulating and those present in the equipment that cannot be replaced yet because of the context of the companies that keep it. Generally, the control mechanisms for classifying the type of substances, equipment and companies that own them, are carried in physical files, spreadsheets and text documents, which makes it difficult to control and manage the data stored in them. Method: The objective of this research is to computerize the process of control of substances that deplete the ozone layer. An evaluation and description of all process to manage Ozone-Depleting Substances (ODS, and its alternatives, is done. For computerization, the agile development methodology SCRUM is used, and for the technological solution tools and free open source technologies are used. Result: As a result of the research, a computer tool was developed that automates the process of control and management of substances that exhaust the ozone layer and its alternatives. Conclusions: The developed computer tool allows to control and manage the ozone-depleting substances and the equipment that use them. It also manages the substances that arise as alternatives to be used for the protection of the ozone layer.

    Lower rates of substance abuse are found among Black Americans compared to Whites, but little is known about differences in substance abuse across ethnic groups within the black population. We examined prevalence rates of substance abuse among Blacks across three geographic regions (US, Jamaica, Guyana). The study also sought to ascertain whether length of time, national context and major depressive episodes (MDE) were associated with substance abuse. We utilized three different data sources based upon probability samples collected in three different countries. The samples included 3,570 African Americans and 1,621 US Caribbean Black adults from the 2001-2003 National Survey of American Life (NSAL). An additional 1,142 Guyanese Blacks and 1,176 Jamaican Blacks living in the Caribbean region were included from the 2005 NSAL replication extension study, Family Connections Across Generations and Nations (FCGN). Mental disorders were based upon DSM-IV criteria. For the analysis, we used descriptive statistics, chi-square, and multivariate logistic regression analytic procedures. Prevalence of substance abuse varied by national context, with higher rates among Blacks within the United States compared to the Caribbean region. Rates of substance abuse were lower overall for women, but differ across cohorts by nativity and length of time in the United States, and in association with major depressive episode. The study highlights the need for further examination of how substance abuse disparities between US-based and Caribbean-based populations may become manifested.

    2014-01-01

    Aim  The purpose of this study was to explore and describe how nurse leaders facilitate safe care from the perspectives of both nurses and nurse leaders. Background  The health-care system's success in improving patient safety pivots on nursing leadership. However, there is a lack of knowledge in the international literature about how nurse leaders facilitate provision of safe care and reaching the goal of a safe health-care system. Method  A qualitative design using a content analysis approach was applied for data gathering and analysis. In this study, 20 nurses (16 nurses and four head nurses) working in a referral teaching hospital in Tehran, Iran, were recruited through purposive sampling. Semi-structured interviews and 10 hours of structured observations were conducted to collect data. Results  The data analysis resulted in three main themes: 'providing environmental prerequisites for safe nursing practice', 'uniting and integrating health-care providers', and 'creating an atmosphere of safe care'. Conclusion  The results indicate that to facilitate providing safe care, nurse leaders should improve nurses' working conditions, develop the nurses' practical competencies, assign duties to nurses according to their skills and capabilities, administer appropriate supervision, improve health-care providers' professional relationships and encourage their collaboration, empower nurses and reward their safe practice. Implications for nursing management  Approaching the challenge of patient safety requires the health-care system to combine its efforts and strategies with nursing leadership in its vital role of facilitating safe care and improving patient safety. © 2012 John Wiley & Sons Ltd.

    Spangler, David C; Loyd, Catherine M; Skor, Emily E

    2016-06-23

    Dextromethorphan is a safe, effective cough suppressant, available without a prescription in the United States since 1958. Due to a perceived prevalence of abuse of dextromethorphan by teens, in 2007 the Drug Enforcement Administration requested the Food and Drug Administration evaluate whether dextromethorphan should be recommended for scheduling under the Controlled Substances Act. The Food and Drug Administration held an Advisory Committee meeting in 2010 to provide a scientific and medical evaluation of dextromethorphan and its abuse potential. To address reports of abuse, particularly by teens in the United States, the Consumer Healthcare Products Association initiated an abuse mitigation plan in 2010 with specific goals related to awareness of the behavior, perception of risk, social disapproval, and access to the products. In identifying abuse interventions, experts acknowledge that substance abuse among teens is a highly complex behavior and indicate that the best course of action is to address prevention by focusing on the factors that impact teen behavior. It is noteworthy that the annual prevalence of over-the-counter cough medicine abuse has sharply decreased since 2010. While a true cause-and-effect relationship cannot be assured, the Consumer Healthcare Products Association and its member companies believe that the increased awareness of the issue since the 2010 Food and Drug Administration Advisory Committee meeting, and the subsequent implementation of a well-delivered and targeted abuse mitigation plan that addressed the levers influencing teen decisions is contributing to the observed reduction in abuse. During the period of 2010-2015, reported abuse of dextromethorphan by 8(th), 10(th), and 12(th) graders decreased 35 %. The authors believe this reduction supports the view of the Consumer Healthcare Products Association at the outset of the abuse mitigation plan effort and today: Controlled substance scheduling or prescription requirements would

    2011-04-01

    Substance abuse has often been associated with committing sex offenses. In this article, the following will be reviewed: 1) studies that assessed substance abuse in sex offenders; 2) differences in substance abuse among different types of sex offenders; 3) differences in substance abuse between sex offenders and nonsexual offenders and substance abuse in the normal population; 4) sex offenders' intoxication at the time of the offense; and 5) differences in intoxication at the time of the offense among different types of sex offenders. Studies will be discussed according to the method they used to assess substance abuse, i.e., file research, screening instruments or semi-structured interviews. This review shows that about half of the sex offenders has a history of substance abuse, a quarter to half of the sex offenders has a history of alcohol misuse and that about one fifth to a quarter of the sex offenders has a history of drug misuse. Furthermore, about a quarter to half of the sex offenders appeared to be intoxicated at the time of the offense. The review results in recommendations for future research. Because of the high prevalence of substance abuse in sex offenders it is advisable to routinely screen for substance abuse and, if necessary, to treat substance abuse. Copyright © 2010 Elsevier Ltd.

    Full Text Available Li-Tzy Wu*Department of Psychiatry and Behavioral Sciences, Duke University School of Medicine, Duke University Medical Center, Durham, NC, USA *Li-Tzy Wu is the Editor-in-Chief of Substance Abuse and RehabilitationAbstract: Alcohol, tobacco, and illegal drug use are pervasive throughout the world. Substance use problems are among the major contributors to the global disease burden, which includes disability and mortality. The benefits of treatment far outweigh the economic costs. Despite the availability of treatment services, however, the vast majority of people with substance use disorders do not seek or use treatment. Barriers to and unmet need for evidence-based treatment are widespread even in the United States. Women, adolescents, and young adults are especially vulnerable to adverse effects from substance abuse, but they face additional barriers to getting evidence-based treatment or other social/medical services. Substance use behaviors and the diseases attributable to substance use problems are preventable and modifiable. Yet the ever-changing patterns of substance use and associated problems require combined research and policy-making efforts from all parts of the world to establish a viable knowledge base to inform for prevention, risk-reduction intervention, effective use of evidence-based treatment, and rehabilitation for long-term recovery. The new international, open-access, peer-reviewed Substance Abuse and Rehabilitation (SAR journal strives to provide an effective platform for sharing ideas for solutions and disseminating research findings globally. Substance use behaviors and problems have no boundaries. The journal welcomes papers from all regions of the world that address any aspect of substance use, abuse/dependence, intervention, treatment, and policy. The “open-access” journal makes cutting edge knowledge freely available to practitioners and researchers worldwide, and this is particularly important for addressing

    In activists' circles as in sociology, the concept "safe space" has been applied to all sorts of programs, organizations, and practices. Few studies have specified clearly what safe spaces are and how they support the people who occupy them. We examine one social location typically understood to be a safe space: gay-straight alliance groups in high schools. Using qualitative interviews with young adults in the United States and Canada who have participated in gay-straight alliances, we unpack this complex concept to consider some of the dimensions along which safe spaces might vary. Based on interviews with participants, we derive three interrelated dimensions of safe space: social context, membership, and activity.

    The increase rate of utilization of branched-chain amino acids (BCAA) by muscle is reduced to its plasma concentration during prolonged exercise leading to glycogen. BCAA supplementation would reduce the serum activities of intramuscular enzymes associated with muscle damage. To examine the effects of BCAA administration on fatigue substances (serotonin, ammonia and lactate), muscle damage substances (CK and LDH) and energy metabolism substances (FFA and glucose) after endurance exercise. Subjects (n = 26, college-aged males) were randomly divided into an experimental (n = 13, EXP) and a placebo (n = 13, CON) group. Subjects both EXP and CON performed a bout of cycle training (70% VO2max intensity) to exhaustion. Subject in the EXP were administrated BCAA (78ml/kg·w) prior to the bout of cycle exercise. Fatigue substances, muscle damage substances and energy metabolism substances were measured before ingesting BCAAs and placebos, 10 min before exercise, 30 min into exercise, immediately after exercise, and 30 min after exercise. Data were analyzed by two-way repeated measure ANCOVA, correlation and statistical significance was set at p BCAA decreased serum concentrations of the intramuscular enzymes as CK and LDH following exhaustive exercise. This observation suggests that BCAA supplementation may reduce the muscle damage associated with endurance exercise.

    A concentrator was manufactured on an experimental basis to improve the performance of the concentrator using fluorescent substance and the analysis based on the test result of optical characteristics of the materials composing the concentrator was made. The concentrator is composed of fluorescent substance sandwiched between two acrylic sheets. Organic fluorescent solution prepared by dissolving eosin to alcohol and capsulating with transparent encapsulant was used as the fluorescent substance. The concentration ratio based on the characteristic tests of the fluorescent substance and material of acrylic sheet composing the concentrator and the numerical calculation model was calculated. The results show that the difference between the experimental and calculated values is 10%. The result of calculation based on the numerical model indicates that the energy efficiency is decreased through the concentration ratio is increased in a thin concentrator, because the fluorescence is decreased by the absorption during passing more frequently through the fluorescent layer.

    The use of a microcomputer to maintain controlled substance inventory and record keeping is described. The system maintains perpetual inventories of the central narcotic vault and proof-of-use controlled drug records outstanding at nursing stations. The computerized system has eliminated (1) the delay previously encountered in the posting of transactions from the numeric log to perpetual inventory logs and (2) the potential addition and subtraction errors inherent in a manual system. Computerizing the controlled drug record-keeping system has saved approximately 166 minutes of labor per day, a cost savings of approximately $26. The new system also helps prevent diversion of controlled substances. The computer may also be used for other tasks while not running the controlled substance program. A microcomputer is well suited to the task of controlled-substance record-keeping functions, and the cost of the system (less than $4000) can be quickly recouped in labor savings.

    2008-06-01

    Dialectical behavior therapy (DBT) is a well-established treatment for individuals with multiple and severe psychosocial disorders, including those who are chronically suicidal. Because many such patients have substance use disorders (SUDs), the authors developed DBT for Substance Abusers, which incorporates concepts and modalities designed to promote abstinence and to reduce the length and adverse impact of relapses. Among these are dialectical abstinence, "clear mind," and attachment strategies that include off-site counseling as well as active attempts to find patients who miss sessions. Several randomized clinical trials have found that DBT for Substance Abusers decreased substance abuse in patients with borderline personality disorder. The treatment also may be helpful for patients who have other severe disorders co-occurring with SUDs or who have not responded to other evidence-based SUD therapies.

    Substance use disorders (SUD) are common and individuals who suffer from them are prone to relapse. One of the most common consequences of the use of and withdrawal from substances of abuse is sleep disturbance. Substances of abuse affect sleep physiology, including the neurotransmitter systems that regulate the sleep-wake system. Emerging research now highlights an interactive effect between sleep disorders and substance use. New findings in alcohol and sleep research have utilized sophisticated research designs and expanded the scope of EEG and circadian rhythm analyses. Research on marijuana and sleep has progressed with findings on the effects of marijuana withdrawal on objective and subjective measures of sleep. Treatment studies have focused primarily on sleep in alcohol use disorders. Therapies for insomnia in cannabis disorders are needed. Future research is poised to further address mechanisms of sleep disturbance in alcoholics and the effect of medical marijuana on sleep and daytime functioning.

    Chronic pain and substance use disorders occur commonly among HIV-infected persons. Recent CDC guidelines recommend non-pharmacologic approaches over opioid medications for the management of chronic pain. This is particularly relevant for persons with substance use disorders. Structured physical activity may be an effective strategy for pain reduction. We developed a combined cognitive-behavioral therapy (CBT) + exercise intervention to reduce pain, pain-related disability and substance use and improve physical function in older HIV-infected adults with chronic pain and substance use. We employed established CBT protocols for the intervention, and sought feedback from potential end users when developing the exercise component of the intervention. A total of 27 HIV-infected adults ≥ 50 years of age participated in four focus group sessions. Transcripts were analyzed using thematic analysis. Participant demographics: mean age 54 years; male 81%; Hispanic 48%, Black 33%; treated for substance abuse in the past 52%. Exercise was seen as a desirable activity, but many participants expressed barriers to exercise including fear of pain exacerbation, low physical fitness, and lack of availability of perceived safe spaces for HIV-infected persons. Most participants were receptive to exercise for pain reduction, particularly modalities that provide added psychological benefits of reducing stress and anxiety. Exercise for pain management among older HIV-infected adults with chronic pain and substance use was found to be highly acceptable. However, interventions need to be tailored to the unique needs of this population to address their fears and concerns.

    To examine how midwives and women within a continuity of care midwifery programme in Australia conceptualised childbirth risk and the influences of these conceptualisations on women's choices and midwives' practice. A critical ethnography within a community-based continuity of midwifery care programme, including semi-structured interviews and the observation of sequential antenatal appointments. Eight midwives, an obstetrician and 17 women. The midwives assumed a risk-negotiator role in order to mediate relationships between women and hospital-based maternity staff. The role of risk-negotiator relied profoundly on the trust engendered in their relationships with women. Trust within the mother-midwife relationship furthermore acted as a catalyst for complex processes of identity work which, in turn, allowed midwives to manipulate existing obstetric risk hierarchies and effectively re-order risk conceptualisations. In establishing and maintaining identities of 'safe practitioner' and 'safe mother', greater scope for the negotiation of normal within a context of obstetric risk was achieved. The effects of obstetric risk practices can be mitigated when trust within the mother-midwife relationship acts as a catalyst for identity work and supports the midwife's role as a risk-negotiator. The achievement of mutual identity-work through the midwives' role as risk-negotiator can contribute to improved outcomes for women receiving continuity of care. However, midwives needed to perform the role of risk-negotiator while simultaneously negotiating their professional credibility in a setting that construed their practice as risky.

    Perfluoroalkyl substances (PFAS) are an emerging class of contaminants. Certain PFAS are regulated or voluntarily limited due to concern about environmental persistence and adverse health effects, including thyroid disease and dyslipidemia. The major source of PFAS exposure in the general population is thought to be consumption of seafood. In this analysis we examine PFAS levels and their determinants, as well as associations between PFAS levels and self-reported fish and shellfish consumption, using a representative sample of the U.S. Data on PFAS levels and self-reported fish consumption over the past 30 days were collected from the 2007-2008, 2009-2010, 2011-2012, and 2013-2014 cycles of the National Health and Nutrition Examination Survey. Twelve different PFAS were measured in serum samples from participants. Ordinary least squares regression models were used to identify factors (demographic characteristics and fish consumption habits) associated with serum PFAS concentrations. Additional models were further adjusted for other potential exposures including military service and consumption of ready-to-eat and fast foods. Seven PFAS were detected in at least 30% of participants and were examined in subsequent analyses (PFDA, PFOA, PFOS, PFHxS, MPAH, PFNA, PFUA). The PFAS with the highest concentrations were PFOS, followed by PFOA, PFHxS and PFNA (medians of 8.3, 2.7, 1.5 and 1.0ng/mL). Fish consumption was generally low, with a median of 1.2 fish meals and 0.14 shellfish meals, reported over the past 30 days. After adjusting for demographic characteristics, total fish consumption was associated with reduced MPAH, and with elevated PFDE, PFNA and PFuDA. Shellfish consumption was associated with elevations of all PFAS examined except MPAH. Certain specific fish and shellfish types were also associated with specific PFAS. Adjustment for additional exposure variables resulted in little to no change in effect estimates for seafood variables. PFAS are emerging

    2006-12-01

    Substance use initiation and frequency are associated with reduced educational attainments among adolescents. We examined if decreases in substance use substantially improve youths' school attendance. A total of 1084 US adolescents followed quarterly for 1 year after entering substance abuse treatment. Random and fixed effects regression models were used to differentiate the lagged effects of drug use from other time-varying and time-invariant covariates. Self-reports of alcohol, marijuana, stimulants, sedatives, hallucinogens and other drug use were used to predict subsequent school attendance, after controlling for demographic and drug use history characteristics, problem indices and other covariates. Reductions in the frequency of alcohol, stimulants and other drug use and the elimination of marijuana use were each associated independently with increased likelihoods of school attendance. Because years of completed schooling is highly correlated with long-term social and economic outcomes, the possibility that reductions in substance use may improve school attendance has significant implications for the cost-effectiveness of substance abuse treatment and other interventions designed to reduce adolescents' substance use.

    Substance use is generally initiated in adolescence or early adulthood and is commonly associated with several physical, psychological, emotional and social problems. The objective of this study is to assess the age of onset of substance use differences on psychosocial problems among individuals with substance use disorders (SUDs) residing in drug rehabilitation centers. A descriptive cross sectional research design was carried out. Probability Proportional to Size (PPS) sampling technique was used to select the drug rehabilitation centers and all the respondents meeting the inclusion criteria of the selected seven rehabilitation centers were taken as a sample and comprised of 221 diagnosed individuals with SUDs. A semi structured self administered questionnaires were used to collect the information regarding demographic and substance use related characteristics. A standard tool Drug Use Screening Inventory-Revised (DUSI-R) was used to assess the psychosocial problems among individuals with SUDs. Data were analyzed using both descriptive and inferential statistics. Multivariate general linear model (MANOVA and MANCOVA) was used to evaluate differences in psychosocial problems between early vs late onset substance users. The age of onset of substance use was significantly associated with psychosocial problems. The mean psychosocial problem scores were higher in early onset substance user (17 years or younger) than late onset substance user (18 years or higher) in various domains of DUSI-R even after controlling confounding factors. The two groups (early vs late) differed significantly in relation to age, gender, occupational status, current types of substance use, frequency of use, mode of substance use and relapse history. The study indicated that early onset substance users are at higher risk for psychosocial problems in various areas of life such as Behavior Pattern, Psychiatric disorder, Family system, Peer relationship, Leisure/Recreation and Work adjustment

    Objective To determine the prevalence of self-reported use of illegal psychoactive substances in a homeless population of the city of Cali. Method Descriptive study of prevalence of period. The target population was 763 homeless people registered during 2010 in the database provided by a temporary shelter facility in the city of Cali. Statistical analysis was performed using R version 3.2.0. Research safe according to the resolution 8430 of 1993. Results 76.9 % of the homeless population recognizes that they consume some type of illegal psychoactive substance (IPAS). The substances with a higher prevalence of use in this population were: marijuana (51.2 %), the crack cocaine (44.6 %) and cocaine (11.3 %). 28.6 % of homeless people were found to consume IPAS more than three times a day and that the main route of administration is smoke (54.7 %). 50% of respondents reported having been hospitalized at some time in a rehabilitation center. Discussion The results in this study show that the problem of PASI consumption significantly affects the population of homeless people, with marijuana and crack cocaine being the most commonly used, which is a complex situation if the easy access of these substances and the severe physical and mental degenerative effects the cause in those who consume them are taken into account. Therefore it is necessary to support initiatives aimed at intervening in this social phenomenon.

    Strobbe, Stephen; Crowley, Melanie

    Alcohol and other substance use by nurses potentially places patients, the public, and nurses themselves at risk for serious injury or death. Nursing students are also at risk for problems related to substance use. When viewed and treated as a chronic medical illness, treatment outcomes for substance use disorders are comparable with those of other diseases and can result in lasting benefits. Professional monitoring programs that employ an alternative-to-discipline approach have been shown to be effective in the treatment of health professionals with substance use disorders and are considered a standard for recovery, with high rates of completion and return to practice. It is the position of the Emergency Nurses Association and the International Nurses Society on Addictions that 1. health care facilities provide education to nurses and other employees regarding alcohol and other drug use and establish policies, procedures, and practices to promote safe, supportive, drug-free workplaces; 2. health care facilities and schools of nursing adopt alternative-to-discipline approaches to treating nurses and nursing students with substance use disorders, with stated goals of retention, rehabilitation, and reentry into safe, professional practice; 3. drug diversion, in the context of personal use, is viewed primarily as a symptom of a serious and treatable disease and not exclusively as a crime; and 4. nurses and nursing students are aware of the risks associated with substance use, impaired practice, and drug diversion and have the responsibility and means to report suspected or actual concerns.

    A new era has dawned in the treatment of chronic hepatitis C (HCV) virus with the use of direct-acting antiviral medications augmenting combination therapy. Unfortunately, the significant impact of improvements may not be realized if antiviral treatment is not expanded to include a larger proportion of patients, many of whom have coexisting mental health and/or substance abuse issues and have been historically deferred from treatment. We reviewed the extent literature on HCV treatment for individuals with co-occurring mental health and/or substance abuse issues. A number of empirically-based arguments exist in favor of treating HCV-infected individuals with mental health and/or substance abuse issues within the context of multidisciplinary team approaches. Integrated, collaborative, or hybrid models of care are just a few examples of multidisciplinary approaches that can combine the care of HCV treating providers with mental health and/or addictions providers to safely and effectively treat these patients. Collectively, these arguments and the empirical evidence that supports them, provides a strong rationale for why expanding antiviral therapy to these patients is critical and timely. A decade of evidence suggests that HCV-infected individuals with mental health and/or substance abuse issues can safely and effectively undergo antiviral treatment when delivered through multidisciplinary care settings. Multidisciplinary approaches that combine HCV treating providers with mental health, addictions, and other support systems can facilitate preparation and successful treatment of these patients on antiviral therapy.

    To evaluate safety and feasibility in a first-in-human trial of a direct magnetic resonance imaging (MRI)-guided prostate biopsy using a novel robotic device. MrBot is an MRI-safe robotic device constructed entirely with nonconductive, nonmetallic, and nonmagnetic materials and developed by our group. A safety and feasibility clinical trial was designed to assess the safety and feasibility of a direct MRI-guided biopsy with MrBot and to determine its targeting accuracy. Men with elevated prostate-specific antigen levels, prior negative prostate biopsies, and cancer-suspicious regions (CSRs) on MRI were enrolled in the study. Biopsies targeting CSRs, in addition to sextant locations, were performed. Five men underwent biopsy with MrBot. Two men required Foley catheter insertion after the procedure, with no other complications or adverse events. Even though this was not a study designed to detect prostate cancer, biopsies confirmed the presence of a clinically significant cancer in 2 patients. On a total of 30 biopsy sites, the robot achieved an MRI-based targeting accuracy of 2.55 mm and a precision of 1.59 mm normal to the needle, with no trajectory corrections and no unsuccessful attempts to target a site. Robot-assisted MRI-guided prostate biopsy appears safe and feasible. This study confirms that a clinically significant prostate cancer (≥5-mm radius, 0.5 cm 3 ) depicted in MRI may be accurately targeted. Direct confirmation of needle placement in the CSR may present an advantage over fusion-based technology and gives more confidence in a negative biopsy result. Additional study is warranted to evaluate the efficacy of this approach. Copyright © 2017 Elsevier Inc. All rights reserved.

  5. The Relationship Between Controlled Substances and Violence.

    2016-01-01

    A causal relationship between controlled substances and firearm violence has been widely assumed in the United States, and federal law prohibits individuals who are "unlawful users of or addicted to any controlled substance" from purchasing or possessing firearms (68 FR 3750. 2003. Codified at 27 CFR §478.11). However, the law does a poor job of defining "unlawful users," resulting in recent calls for a revised, actionable definition. Such a definition should be informed by research evidence, but to date the epidemiologic research on the relationship between controlled substances and violence has not been comprehensively reviewed. The initial goal of this review was to summarize the best available evidence on the relationship between controlled substances and firearm violence, but only 1 study specific to firearm violence was identified. We therefore reviewed studies of this relationship using broader measures of interpersonal violence and suicide, all of which included but were not limited to firearm violence, and measures of illicit firearm carrying. Prospective longitudinal studies (n = 22) from 1990 to 2014 were identified by using searches of online databases and citation tracking. Information was extracted from each study by using a standardized protocol. Quality of evidence was independently assessed by 2 reviewers. Aggregate measures of controlled substance use were associated with increased interpersonal violence and suicide, but evidence regarding the relationship between specific substances and violence was mixed. Involvement in illegal drug sales was consistently associated with interpersonal violence. To effectively revise extant federal law and delineate appropriate prohibiting criteria, more research is needed to understand the relationship between controlled substances and firearm violence. © The Author 2016.

    In South Asia, the technological and societal shift from drinking surface water to groundwater has resulted in a great reduction of acute diseases due to water borne pathogens. However, arsenic and other naturally occurring inorganic toxic substances present in groundwater in the region have been linked to a variety of chronic diseases, including cancers, heart disease, and neurological problems. Due to the highly specific symptoms of chronic arsenic poisoning, arsenic was the first inorganic toxic substance to be noticed at unsafe levels in the groundwater of West Bengal, India and Bangladesh. Subsequently, other inorganic toxic substances, including manganese, uranium, and fluoride have been found at unsafe levels in groundwater in South Asia. While numerous drinking water wells throughout Myanmar have been tested for arsenic, relatively little is known about the concentrations of other inorganic toxic substances in Myanmar groundwater. In this study, we analyzed samples from 18 drinking water wells (12 in Myingyan City and 6 in nearby Tha Pyay Thar Village) and 2 locations in the Ayeyarwaddy River for arsenic, boron, barium, beryllium, cadmium, cobalt, chromium, copper, fluoride, iron, mercury, manganese, molybdenum, nickel, lead, antimony, selenium, thallium, uranium, vanadium, and zinc. Concentrations of arsenic, manganese, fluoride, iron, or uranium exceeded health-based reference values in most wells. In addition, any given well usually contained more than one toxic substance at unsafe concentrations. While water testing and well sharing could reduce health risks, none of the wells sampled provide water that is entirely safe with respect to inorganic toxic substances. It is imperative that users of these wells, and users of other wells that have not been tested for multiple inorganic toxic substances throughout the region, be informed of the need for drinking water testing and the health consequences of drinking water contaminated with inorganic toxic

    Roesler, Alexander W [Tijeras, NM; Wooden, Susan M [Sandia Park, NM

    2009-05-12

    Microelectromechanical (MEM) safe-arm devices comprise a substrate upon which a sense mass, that can contain an energetic material, is constrained to move along a pathway defined by a track disposed on the surface of the substrate. The pathway has a first end comprising a "safe" position and a second end comprising an "armed" position, whereat the second end the sense mass can be aligned proximal to energetic materials comprising the explosive train, within an explosive component. The sense mass can be confined in the safe position by a first latch, operable to release the sense mass by an acceleration acting in a direction substantially normal to the surface of the substrate. A second acceleration, acting in a direction substantially parallel to the surface of the substrate, can cause the sense mass to traverse the pathway from the safe position to the armed position.

  1. A Wearable Goggle Navigation System for Dual-Mode Optical and Ultrasound Localization of Suspicious Lesions: Validation Studies Using Tissue-Simulating Phantoms and an Ex Vivo Human Breast Tissue Model.

    Directory of Open Access Journals (Sweden)

    Zeshu Zhang

    Full Text Available Surgical resection remains the primary curative treatment for many early-stage cancers, including breast cancer. The development of intraoperative guidance systems for identifying all sites of disease and improving the likelihood of complete surgical resection is an area of active ongoing research, as this can lead to a decrease in the need of subsequent additional surgical procedures. We develop a wearable goggle navigation system for dual-mode optical and ultrasound imaging of suspicious lesions. The system consists of a light source module, a monochromatic CCD camera, an ultrasound system, a Google Glass, and a host computer. It is tested in tissue-simulating phantoms and an ex vivo human breast tissue model. Our experiments demonstrate that the surgical navigation system provides useful guidance for localization and core needle biopsy of simulated tumor within the tissue-simulating phantom, as well as a core needle biopsy and subsequent excision of Indocyanine Green (ICG-fluorescing sentinel lymph nodes. Our experiments support the contention that this wearable goggle navigation system can be potentially very useful and fully integrated by the surgeon for optimizing many aspects of oncologic surgery. Further engineering optimization and additional in vivo clinical validation work is necessary before such a surgical navigation system can be fully realized in the everyday clinical setting.

    This study tested the hypothesis that playing video games while using or feeling the effects of a substance--referred to herein as "concurrent use"-is related to substance use problems after controlling for substance use frequency, video gaming as an enthusiastic hobby, and demographic factors. Data were drawn from a nationally representative online survey of adult video gamers conducted by Knowledge Networks, valid n = 2,885. Problem video game playing behavior was operationalized using Tejeiro Salguero and Bersabé Morán's 2002 problem video game play (PVP) measure, and measures for substance use problems were taken from the National Survey of Drug Use and Health (NSDUH). Separate structural equation modeling analyses were conducted for users of caffeine, tobacco, alcohol, and marijuana. In all four models, concurrent use was directly associated with substance use problems, but not with PVP. Video gaming as an enthusiastic hobby was associated with substance use problems via two indirect paths: through PVP for all substances, and through concurrent use for caffeine, tobacco, and alcohol only. Results illustrate the potential for "drug interaction" between self-reinforcing behaviors and addictive substances, with implications for the development of problem use.

    Full Text Available Blood transfusion is a life saving procedure in various transfusion-dependent life threatening conditions and donation of safe blood is a prerequisite for achieving this goal. This study was designed to evaluate the awareness regarding “safe blood” in Pakistani population. This study was conducted at a large scale through a population survey. The test population was divided into two groups i.e. general population and students. The Performa was designed for a general and student population and included 20 questions related to awareness of safe blood. A total of 4900 individuals belonging to different ethnic groups were included in this population survey. Results of social survey were analyzed by using Usman and Moin awareness chart. Results of this study revealed profound unawareness about safe blood in Pakistani population. This study found lack of awareness about safe blood as a major factor that is playing a vital role in the propagation of blood borne diseases in Pakistan. To secure the recipients from blood borne complications through blood donation, it is necessary to create effective awareness about safe blood in Pakistani population.

  7. The Safe Yield and Climatic Variability: Implications for Groundwater Management.

    2017-05-01

    Methods for calculating the safe yield are evaluated in this paper using a high-quality and long historical data set of groundwater recharge, discharge, extraction, and precipitation in a karst aquifer. Consideration is given to the role that climatic variability has on the determination of a climatically representative period with which to evaluate the safe yield. The methods employed to estimate the safe yield are consistent with its definition as a long-term average extraction rate that avoids adverse impacts on groundwater. The safe yield is a useful baseline for groundwater planning; yet, it is herein shown that it is not an operational rule that works well under all climatic conditions. This paper shows that due to the nature of dynamic groundwater processes it may be most appropriate to use an adaptive groundwater management strategy that links groundwater extraction rates to groundwater discharge rates, thus achieving a safe yield that represents an estimated long-term sustainable yield. An example of the calculation of the safe yield of the Edwards Aquifer (Texas) demonstrates that it is about one-half of the average annual recharge. © 2016, National Ground Water Association.

    2015-08-01

    The purpose of this study was to develop guidelines for Korean consumers with regard to safe food handling practices at home by identifying current food handling issues. Korean consumers' behaviors regarding their safe food handling were identified via survey questionnaires that included items on individual hygiene practices, prepreparation steps when cooking, the cooking process, and the storage of leftover foods. The subjects were 417 Korean parents with elementary school children living in Seoul and Gyeonggi Province in the central area of Korea. The survey results revealed gaps between the knowledge or practices of Korean consumers and scientific evidence pertaining to safe food handling practices. Based on these findings, a leaflet on safe food handling guidelines was developed in accordance with Korean food culture. These guidelines suggest personal hygiene practices as well as fundamental principles and procedures for safe food handling from the stage of food purchase to that of keeping leftover dishes. A pilot application study with 50 consumers revealed that the guidelines effectively improved Korean consumers' safe food handling practices, suggesting that they can serve as practical educational material suitable for Korean consumers.

    Full Text Available Purpose: (1 To compare sensory processing patterns as expressed in daily life between substance dependents and typical controls; (2 profile the prevalence of sensory processing disorders (SPD among substance dependents; and (3 examine gender effect on SPD within and between groups. Methods: Two hundred ninety people aged 19-64 participated in this study. The study group included 145 individuals who lived in the community or took part in an outpatient program because of addiction to drugs/alcohol and had been clean for over three months. The control group included 145 individuals who were not exposed to drugs or alcohol on a regular basis and did not suffer from addictive behavior. All participants filled a demographic questionnaire. Those who met the inclusion criteria completed the Adolescent/Adult Sensory Profile (AASP so that their sensory processing patterns could be assessed. Results: When comparing both groups, the study group showed greater sensory sensitivity and significantly higher prevalence of SPD. Significant group/gender interaction was found in regard to sensation seeking. Discussion: SPD among substance dependents may be expressed in daily life by either hypersensitivity or hyposensitivity. The behavioral outcomes reflected by the AASP support neurophysiological manifestations about SPD of substance dependents. The evaluation process of substance dependents should refer to their sensory processing abilities. In case SPD is diagnosed, Occupational Therapy and specific sensory–based interventions should be considered in order to fit the specific needs of individuals and enhance their performance, meaningful participation, and quality of life.

    2015-03-01

    Nursing staff on psychiatric wards often attribute patient violence and aggression to substance use. This study examined incidents of alcohol and illicit drug use among acute psychiatric inpatients and associations between substance use and violence or other forms of aggression. A sample of 522 adult psychiatric inpatients was recruited from 84 acute psychiatric wards in England. Data were collected from nursing and medical records for the first 2 weeks of admission. Only a small proportion of the sample was reported to have used or been under the influence of alcohol (5%) or drugs (3%). There was no physical violence during a shift when a patient had used alcohol or drugs. Substance using patients were also no more likely than others to behave violently at any point during the study period. However, incidents of substance use were sometimes followed by verbal aggression. Beliefs that substance using patients are likely to be violent were not supported by this study, and could impact negatively on therapeutic relationships between nurses and this patient group. Future studies are needed to examine how staff intervene and interact with intoxicated patients. © 2014 John Wiley & Sons Ltd.

    Many studies have suggested the importance of peer influence and personal attitudes (e.g., expectancies, resistance self-efficacy, and perceived harm) in predicting adolescent use of illegal substances. The present study examined these variables in relation to self-reported use of alcohol, cigarettes, and marijuana for 213 younger adolescents (12-15 years old) and 219 older adolescents (18-22 years old). A series of logistic regressions was performed to assess variables relating to use of each substance by age group and gender. Friends' use was significantly related to substance use for both age groups, both sexes, and all substances examined in this study. Perceived harm was not significantly related to use for any group. Finally, outcome expectancies and resistance self-efficacy were differentially related to use depending on age, gender, and substance. The implications of these findings for prevention programming and future research are also discussed.

    The Safe Affordable Fission Engine (SAFE) test series addresses Phase 1 Space Fission Systems issues in particular non-nuclear testing and system integration issues leading to the testing and non-nuclear demonstration of a 400-kW fully integrated flight unit. The first part of the SAFE 30 test series demonstrated operation of the simulated nuclear core and heat pipe system. Experimental data acquired in a number of different test scenarios will validate existing computational models, demonstrated system flexibility (fast start-ups, multiple start-ups/shut downs), simulate predictable failure modes and operating environments. The objective of the second part is to demonstrate an integrated propulsion system consisting of a core, conversion system and a thruster where the system converts thermal heat into jet power. This end-to-end system demonstration sets a precedent for ground testing of nuclear electric propulsion systems. The paper describes the SAFE 30 end-to-end system demonstration and its subsystems. .

    Alcohol, tobacco, and illegal drug use are pervasive throughout the world. Substance use problems are among the major contributors to the global disease burden, which includes disability and mortality. The benefits of treatment far outweigh the economic costs. Despite the availability of treatment services, however, the vast majority of people with substance use disorders do not seek or use treatment. Barriers to and unmet need for evidence-based treatment are widespread even in the United States. Women, adolescents, and young adults are especially vulnerable to adverse effects from substance abuse, but they face additional barriers to getting evidence-based treatment or other social/medical services. Substance use behaviors and the diseases attributable to substance use problems are preventable and modifiable. Yet the ever-changing patterns of substance use and associated problems require combined research and policy-making efforts from all parts of the world to establish a viable knowledge base to inform for prevention, risk-reduction intervention, effective use of evidence-based treatment, and rehabilitation for long-term recovery. The new international, open-access, peer-reviewed Substance Abuse and Rehabilitation (SAR) journal strives to provide an effective platform for sharing ideas for solutions and disseminating research findings globally. Substance use behaviors and problems have no boundaries. The journal welcomes papers from all regions of the world that address any aspect of substance use, abuse/dependence, intervention, treatment, and policy. The "open-access" journal makes cutting edge knowledge freely available to practitioners and researchers worldwide, and this is particularly important for addressing the global disease burden attributable to substance abuse.

    Full Text Available Richard B FrancoeurSchool of Social Work, Adelphi University, Garden City, NY, USA; Center for the Psychosocial Study of Health and Illness, Columbia University, New York, NY, USAAbstract: This article proposes and develops novel components of community-oriented programs for creating and affording access to safe medication dispensing centers in existing retail pharmacies and in permanent or travelling pharmacy clinics that are guarded by assigned or off-duty police officers. Pharmacists at these centers would work with police, medical providers, social workers, hospital administrators, and other professionals in: planning and overseeing the safe storage of controlled substance medications in off-site community safe-deposit boxes; strengthening communication and cooperation with the prescribing medical provider; assisting the prescribing medical provider in patient monitoring (checking the state prescription registry, providing pill counts and urine samples; expanding access to lower-cost, and in some cases, abuse-resistant formulations of controlled substance medications; improving transportation access for underserved patients and caregivers to obtain prescriptions; and integrating community agencies and social networks as resources for patient support and monitoring. Novel components of two related community-oriented programs, which may be hosted outside of safe medication dispensing centers, are also suggested and described: (1 developing medication purchasing cooperatives (ie, to help patients, families, and health institutions afford the costs of medications, including tamper- or abuse-resistant/deterrent drug formulations; and (2 expanding the role of inner-city methadone maintenance treatment programs in palliative care (ie, to provide additional patient monitoring from a second treatment team focusing on narcotics addiction, and potentially, to serve as an untapped source of opioid medication for pain that is less subject to abuse

    Introduction Theoretic models suggest that associations between substance use and dating violence perpetration may vary in different social contexts, but few studies have examined this proposition. The current study examined whether social control and violence in the neighborhood, peer, and family contexts moderate the associations between substance use (heavy alcohol use, marijuana, and hard drug use) and adolescent physical dating violence perpetration. Methods Adolescents in the eighth, ninth, and tenth grades completed questionnaires in 2004 and again four more times until 2007 when they were in the tenth, 11th and 12th grades. Multilevel analysis was used to examine interactions between each substance and measures of neighborhood, peer, and family social control and violence as within-person (time-varying) predictors of physical dating violence perpetration across eighth through 12th grade (N=2,455). Analyses were conducted in 2014. Results Physical dating violence perpetration increased at time points when heavy alcohol and hard drug use were elevated; these associations were weaker when neighborhood social control was higher and stronger when family violence was higher. Also, the association between heavy alcohol use and physical dating violence perpetration was weaker when teens had more-prosocial peer networks and stronger when teens’ peers reported more physical dating violence. Conclusions Linkages between substance use and physical dating violence perpetration depend on substance use type and levels of contextual violence and social control. Prevention programs that address substance use–related dating violence should consider the role of social contextual variables that may condition risk by influencing adolescents’ aggression propensity.

    Although detoxification cannot, in itself, be considered a treatment for addiction, it is one of the most pivotal phases. In order to facilitate entry into recovery and/or rehabilitation programs, a detoxification treatment has to be experienced as easy and safe by the patient. In consideration of the many inconveniences related to standard withdrawal treatments, there is an interest in developing alternative pharmacological strategies. The main rationales for using anticonvulsants in substance-abuse patients are their lack of addiction potential, evidence support a role of kindling mechanisms in withdrawal syndromes and their efficacy in comorbid psychiatric disorders. The available data currently support the utilization of carbamazepine as a treatment for detoxification from benzodiazepines, alcohol and opiates, and as a useful agent to reduce cocaine consumption. The use of valproate is well corroborated for alcohol detoxification and it seems to be a promising treatment for the reduction of cocaine use; however, it has been found to be ineffective against benzodiazepine withdrawal symptoms. Some preliminary data suggest that lamotrigine could be useful in opiate and cocaine dependence. Gabapentin shows potential as a treatment for cocaine dependence, and some case reports have stimulated interest in this agent for alcohol and benzodiazepine detoxification. Due to its particular pharmacological profile, topiramate is one of the most interesting newer anticonvulsants. It has been found to be efficacious in opiate and possibly benzodiazepine detoxification and also has theoretical potential as a preventive therapy.

    2014-03-01

    All sectors of society should be involved in reducing substance misuse, including businesses. However, the business sector is typically involved only to the extent that their products compel them to be (e.g., alcohol producers promoting responsible alcohol consumption). This article examines why business participation has been limited and how embedding prevention within a framework of health promotion could increase participation. It reviews both Hungarian and international cases, concluding that although corporate social responsibility (CSR) offers a framework to approach substance misuse reduction, a different perception of the role of the business sector is necessary to make it viable.

    Despite their huge health toll, substance abuse disorders remain underappreciated and underfunded. Reasons include stigma, tolerance of personal choices, acceptance of youthful experimentation, pessimism about treatment efficacy, fragmented and weak leadership, powerful tobacco and alcohol industries, underinvestment in research, and difficult patients. Positive signs include declining prevalence rates, successful counter-marketing campaigns, changing public attitudes, new scientific discoveries that could yield new treatments, and effective new organizations. Further progress will require better treatment, more research, better education of health professionals, more nongovernmental support, and stronger leadership. Policy changes regarding each of the three substance groups are indicated, as are reforms in the criminal justice and educational systems.

    Sexual minority youth often experience increased social stress due to prejudice, discrimination, harassment, and victimization. Increased stress may help explain the disproportionate use of substances like tobacco, alcohol, marijuana, and other illicit drug use by sexual minority youth. This study examined the effect of social stress on substance use disparities by sexual orientation among U.S. high school students. In 2016, data from the national 2015 Youth Risk Behavior Survey, conducted among a nationally representative sample of 15,624 U.S. high school students, were analyzed to examine the effect of school-related (threatened/injured at school, bullied at school, bullied electronically, felt unsafe at school) and non-school-related (forced sexual intercourse, early sexual debut) social stress on substance use disparities by sexual orientation, by comparing unadjusted prevalence ratios (PRs) and adjusted (for social stressors, age, sex, and race/ethnicity) prevalence ratios (APRs). Unadjusted PRs reflected significantly (p<0.05 or 95% CI did not include 1.0) greater substance use among students who identified as lesbian/gay or bisexual than students who identified as heterosexual. APRs for injection drug use decreased substantially among lesbian/gay (PR=12.02 vs APR=2.14) and bisexual (PR=2.62 vs APR=1.18) students; the APR for bisexual students became nonsignificant. In addition, APRs among both lesbian/gay and bisexual students decreased substantially and were no longer statistically significant for cocaine, methamphetamine, and heroin use. School-based substance use prevention programs might appropriately include strategies to reduce social stress, including policies and practices designed to provide a safe school environment and improved access to social and mental health services.

    This study tested the hypothesis that playing video games while using or feeling the effects of a substance—referred to herein as “concurrent use”—is related to substance use problems after controlling for substance use frequency, video gaming as an enthusiastic hobby, and demographic factors. Data were drawn from a nationally representative online survey of adult video gamers conducted by Knowledge Networks, valid n = 2,885. Problem video game playing behavior was operationalized using Tejeiro Salguero and Bersabé Morán’s 2002 problem video game play (PVP) measure, and measures for substance use problems were taken from the National Survey of Drug Use and Health (NSDUH). Separate structural equation modeling analyses were conducted for users of caffeine, tobacco, alcohol, and marijuana.

    Full Text Available This study tested the hypothesis that playing video games while using or feeling the effects of a substance—referred to herein as “concurrent use”—is related to substance use problems after controlling for substance use frequency, video gaming as an enthusiastic hobby, and demographic factors. Data were drawn from a nationally representative online survey of adult video gamers conducted by Knowledge Networks, valid n = 2,885. Problem video game playing behavior was operationalized using Tejeiro Salguero and Bersabé Morán’s 2002 problem video game play (PVP measure, and measures for substance use problems were taken from the National Survey of Drug Use and Health (NSDUH. Separate structural equation modeling analyses were conducted for users of caffeine, tobacco, alcohol, and marijuana. In all four models, concurrent use was directly associated with substance use problems, but not with PVP. Video gaming as an enthusiastic hobby was associated with substance use problems via two indirect paths: through PVP for all substances, and through concurrent use for caffeine, tobacco, and alcohol only. Results illustrate the potential for “drug interaction” between self-reinforcing behaviors and addictive substances, with implications for the development of problem use.

  12. [Community health building: the safe community promotion experience].

    2011-02-01

    Safety and health promotion at the community level involves special concerns and approaches. A community may develop into a safe community or healthy city depending on the focus of relevant promotion efforts. Neither area nor population size should be factors affecting an initial decision to start safe community or healthy city programs. However, one should consider the diversity of issues that may have the potential impact on people with different gender and age or on different environments and situations, and whether a planned program is sustainable. While safe communities and healthy cities may be linked to international networks, the qualifications for joining such networks differ. The Healthy City Alliance emphasizes outcome measures and the International Safe Community Network emphasizes the appropriateness of sustainability mechanisms. While Taiwan communities are eligible for designation as international safe communities, they may are eligible for associate membership only in the Healthy City Alliance. The author has the following recommendations with regard to sustainability in community health building in Taiwan: 1) The relevant infrastructure must involve both public and private sectors; 2) The community should try to receive financial support from diverse sources; 3) involve significant numbers of active volunteers; and 4) charge local health centers with data collection and analysis responsibilities.

    This paper enumerates different kinds of substances that are believed to cause cancer, and discusses how they behave in their quantitative evaluation on carcinogenic effects in human bodies. About 600 carcinogenic substances have been discovered from experimental animals, of which about 50 substances have been identified to clearly cause human cancer. The quantitative risk evaluation is performed by combining mainly two items; information of intensities of carcinogenic effects and human intake of the substances. An amount of a substance that raises a carcinogenic frequency by as much as a one million fraction when lifetime experimental animals are dosed with the substance is called a virtually safe dosage (VSD). According to calculations, the amount of BHA, a food additive for example, that is taken by Japanese people from different kinds of oils is 1/70 of the VSD, a very small contribution to occurrences of human cancer. Carcinogenic substances cannot explain, with very few exceptions, the occurrence of human cancer quantitatively. Living practices should rather be changed and improved. 5 refs.

    Crashes are the leading cause of death for teens, and parent-based interventions are a promising approach. We assess the effectiveness of Steering Teens Safe, a parent-focused program to increase safe teen driving. Steering Teens Safe aimed to improve parental communication with teens about safe driving using motivational interviewing techniques in conjunction with 19 safe driving lessons. A randomized controlled trial involved 145 parent-teen dyads (70 intervention and 75 control). Intervention parents received a 45-minute session to learn the program with four follow-up phone sessions, a DVD, and a workbook. Control parents received a standard brochure about safe driving. Scores were developed to measure teen-reported quantity and quality of parental communication about safe driving. The main outcome measure was a previously validated Risky Driving Score reported by teens. Because the Score was highly skewed, a generalized linear model based on a gamma distribution was used for analysis. Intervention teens ranked their parent's success in talking about driving safety higher than control teens (p = 0.035) and reported that their parents talked about more topics (non-significant difference). The Risky Driving Score was 21% lower in intervention compared to control teens (85% CI = 0.60, 1.00). Interaction between communication quantity and the intervention was examined. Intervention teens who reported more successful communication had a 42% lower Risky Driving Score (95% CI = 0.37, 0.94) than control parents with less successful communication. This program had a positive although not strong effect, and it may hold the most promise in partnership with other programs, such as Driver's Education or Graduated Driver's License policies.

    This study evaluated whether sexual orientation-specific differences in substance use behaviors exist among adults entering substance abuse treatment. Admissions records (July 2007-December 2009) were examined for treatment programs in San Francisco, California receiving government funding. Lesbian, gay, and bisexual (LGB) persons (n = 1,441) were compared to heterosexual persons (n = 11,770) separately by sex, examining primary problem substance of abuse, route of administration, age of first use, and frequency of use prior to treatment. Regarding bisexual males, the only significant finding of note was greater prevalence of methamphetamine as the primary substance of abuse. When compared to heterosexual men, gay and bisexual men evidenced greater rates of primary problem methamphetamine use (44.5% and 21.8%, respectively, vs. 7.7%, adjusted odds ratios [ORs] 6.43 and 2.94), and there was lower primary heroin use among gay men (9.3% vs. 25.8%, OR 0.35). Among LGB individuals, race and ethnicity did not predict primary problem substance, except that among LGB men and women, a non-White race predicted cocaine use (OR 4.83 and 6.40, respectively), and among lesbian and bisexual women, Hispanic ethnicity predicted lower odds of primary cocaine use (OR 0.24). When compared to heterosexual men, gay men were more likely to smoke their primary problem substance (OR 1.61), first used this substance at an older age (M = 23.16 vs. M = 18.55, p substance fewer days prior to treatment (M = 8.75 vs. M = 11.41, p substance use for gay and bisexual men entering substance abuse treatment, but women did not evidence differences. Gay men evidenced unique factors that may reflect less severity of use when entering treatment including fewer days of use and a later age of initiation of their primary problem substances. The results underscore the importance of being sensitive to differences between gay, bisexual, and heterosexual males when considering substance use disorders. (Psyc

    2009-01-01

    The dibenzofuran usnic acid, a widespread cortical secondary metabolite produced by lichen-forming fungi, was shown to promote the intracellular uptake of Cu(2+) in two epiphytic lichens, Evernia mesomorpha and Ramalina menziesii, from acidic, nutrient-poor bark. Higher Cu(2+) uptake in the former, which produces the depside divaricatic acid in addition to usnic acid, suggests that this depside promotes Cu(2+) uptake. Since Cu(2+) is one of the rarest micronutrients, promotion of Cu(2+) uptake by lichen substances may be crucial for the studied lichens to survive in their nutrient-poor habitats. In contrast, study of the uptake of other metals in E. mesomorpha revealed that the intracellular uptake of Mn(2+), which regularly exceeds potentially toxic concentrations in leachates of acidic tree bark, was partially inhibited by the lichen substances produced by this species. Inhibition of Mn(2+) uptake by lichen substances previously has been demonstrated in lichens. The uptake of Fe(2+), Fe(3+), Mg(2+), and Zn(2+), which fail to reach toxic concentrations in acidic bark at unpolluted sites, although they are more common than Cu(2+), was not affected by lichen substances of E. mesomorpha.

  11. Substance abuse in older adults: policy issues.

    Gage, Susan; Melillo, Karen Devereaux

    2011-12-01

    By 2020, it is projected that the number of older adults needing treatment for drug and alcohol addictions will increase dramatically. Although Medicare covers treatment for mental health issues, copayments can be prohibitive for those with lower incomes. The Positive Aging Act, an amendment to the Public Health Service Act, is a policy alternative that could address substance abuse in the older adult population by (a) demonstrating ways of integrating mental health services for older adults into primary care settings, and (b) supporting the establishment and maintenance of interdisciplinary geriatric mental health outreach teams in community settings where older adults reside or receive social services. Increasing funding to states to emphasize primary care provider education on the detection, evaluation, and treatment of substance abuse problems of older adults has the potential to better meet the substance abuse needs of this population. Educating primary care providers, including gerontological nurses, to recognize signs of substance abuse in this population and providing age-appropriate treatment options is critically important but will require funding beyond what is currently available.

    Several states have proposed laws that urine drug screening be performed as a part of qualifying for public assistance. At least one state (Florida) has passed such a law, and several other states are considering similar laws. The Oklahoma Commission on Children and Youth created a committee to study laws and policies regarding the use of illegal drugs while pregnant. To get a better understanding of drug screening and pregnancy, 151 consecutive obstetrical patients receiving Medicaid were screened at their initial obstetrical visit by verbal and written questionnaire's concerning the use of alcohol, nicotine, and other illicit\\dangerous drugs; in addition a urine drug screen for the use of illicit or dangerous drugs was performed. The patient histories regarding the use of dangerous or illicit substances was reviewed and compared with the urine drug screens performed at the same visit. The authors note that when studied the incidence of substance abuse has been similar in patient population receiving public assistance and patient populations with traditional insurance. Oklahoma is one of 13 states with laws requiring mandatory reporting of substance abuse in pregnancy or the exposure of the newborn to illicit substances.

    2002-01-01

    Due to the fact that various research studies have shown that drug users usually have a father with negative characteristics, it is convenient to investigate this phenomenon and take it into consideration in addict treatment efforts. This is a qualitative study that explores the fatherly perception among male substance users. The sample included 25 users who asked for treatment at Youth Integration Center and 25 non-users. Both groups were subjected to projective tests. The father image among substance users emphasizes negative characteristics; in contrast, non-users present a basically positive father perception, considering him as the most valuable family member. These data show that substance users relate less with the fatherly figure than non-users. They perceive their father as a devaluated member that occupies a secondary place in the family and sometimes does not even have an affective role. The findings of this investigation can be applied in individual psychotherapy, facilitating the revaluation and reflection of the fatherly figure among substance users. It would be convenient to create the necessary conditions to restitute the father role in family therapy and counseling groups for relatives. The findings must consider the size of the sample and limitations of qualitative research methology.
