    The list of prohibited substances and methods (the List) is the international standard that determines what is prohibited in sport both in- and out-of-competition. Since 2004, the official text of the List is produced by the World Anti-Doping Agency (WADA), the international independent organization responsible for promoting, coordinating, and monitoring the fight against doping in sport. Originally based on the prohibited lists established by the International Olympic Committee, the List has evolved to incorporate new doping trends, distinguish permitted from prohibited routes of administration, and adjust to new analytical and pharmacological breakthroughs. In this chapter, the elements that compose the List as well as the updates over the years are presented. © 2017 S. Karger AG, Basel.

    This study investigated athlete knowledge of the World Anti-doping Agency (WADA) Prohibited Substances List and the effects of four well-known performance enhancing substances (PES). A sample of 1925 elite and sub-elite athletes (mean age 20.6 years) completed a questionnaire about the banned status of 30 substances/methods and their knowledge of the effects of amphetamines, anabolic steroids, growth hormone and erythropoietin. Athletes showed limited understanding of the WADA Prohibited Substances List, scoring 32.2% correct, 36.3% incorrect, and 31.4% indicated they did not know the status of 30 substances. Responses of >50% correct were given for only eight substances/method: anabolic steroids, amphetamines, blood doping, erythropoietin, caffeine, vitamins/minerals, protein powders and iron. Athletes demonstrated moderate knowledge of the desired effects of the four PES (49% correct), but poor knowledge of their adverse effects (29% correct). Age, sex, ethnicity, professional/amateur status, and current competition level were significant predictors of the number of correct responses (r 2  = 0.16, p wide range of substances and PES. Better targeted drug education towards younger and non-professional athletes and evaluation of current anti-doping programs are warranted. Copyright © 2018 Elsevier B.V. All rights reserved.

    To estimate the lifetime prevalence and address the attitudes and knowledge of using prohibited substances (doping) among sport players in Saudi Arabia. A cross-sectional survey carried out using systematic random sampling technique among Saudi players of variable sports attending the sport clubs, stadiums, and sport fields (70 sport clubs, 22 types of sports belong to 22 Saudi sport federations were visted in 18 cities from all regions of Saudi Arabia). A total of 1142 male sport players were interviewed with main age of 24. The prevalence of using prohibited substances (doping) was 4.3 %. The main reason for using prohibited substances was to improve performance (69 %). The prevalence of using food supplements (not prohibited) was 38.4 %. Among the players, 30 % of them believe that such behavior is against the spirit of sport while 70 % of the players are aware of punishment against doping. 65 % of players admitted that they received advice on prohibited substances. Higher rate of using prohibited substances (doping) among Saudi players was associated with low education, age below 20 years, previous use of food supplements and lack of punishment awareness. Using prohibited substances (doping) among Saudi sport players is common. Players believe that such use is against the spirit of the sport and they are aware about its punishment, despite this, they are still using prohibited substances.

    2009-06-01

    Full Text Available Substances with anabolic effects are used to enhance feed conversion, growth rate or muscle tissue deposition in stock farming for several decades. The majority of these compounds have biochemical effects similar to sex steroids (androgens, estrogens, gestagens. However, in the E.U., the use of hormones for growth – promotion or fattening is prohibited. Monitoring of residues of hormonal growth-promotion in meat or milk, is essential for implementing such bans and to protect public health against the harmful effects of these substances, which incidentally is found in products of animal origin.

    The annual suicide rate in South Korea is the highest among the developed countries. Paraquat is a highly lethal herbicide, commonly used in South Korea as a means for suicide. We have studied the effect of the 2011 paraquat prohibition on the national suicide rate and method of suicide in South Korea. We obtained the monthly suicide rate from 2005 to 2013 in South Korea. In our analyses, we adjusted for the effects of celebrity suicides, and economic, meteorological, and seasonal factors on suicide rate. We employed change point analysis to determine the effect of paraquat prohibition on suicide rate over time, and the results were verified by structural change analysis, an alternative statistical method. After the paraquat prohibition period in South Korea, there was a significant reduction in the total suicide rate and suicide rate by poisoning with herbicides or fungicides in all age groups and in both genders. The estimated suicide rates during this period decreased by 10.0% and 46.1% for total suicides and suicides by poisoning of herbicides or fungicides, respectively. In addition, method substitution effect of paraquat prohibition was found in suicide by poisoning by carbon monoxide, which did not exceed the reduction in the suicide rate of poisoning with herbicides or fungicides. In South Korea, paraquat prohibition led to a lower rate of suicide by paraquat poisoning, as well as a reduction in the overall suicide rate. Paraquat prohibition should be considered as a national suicide prevention strategy in developing and developed countries alongside careful observation for method substitution effects.

  16. The impact of New Zealand's 2008 prohibition of piperazine-based party pills on young people's substance use: results of a longitudinal, web-based study.

    Science.gov (United States)

    Sheridan, Janie; Dong, Christine Yang; Butler, Rachael; Barnes, Joanne

    2013-09-01

    The last decade has seen the emergence of a new phenomenon in recreational substance use with the availability of herbal and synthetic, unregulated, psychoactive drugs in the market place; alongside this, international concern has developed in relation to their use and associated harms. New Zealand (NZ) was one of the first countries to experience this new phenomenon, with products containing chemicals of the piperazine group - mainly benzylpiperazine (BZP) and trifluoromethylphenylpiperazine (TFMPP). In 2008, the NZ Government prohibited these substances, but allowed a 6-month amnesty period for possession. Our study aimed to obtain a measure of change in BZP use over time. This study used a longitudinal, web-based survey, with data collected at two time points from the same participants. The first survey was carried out 3 months after BZP prohibition, and included retrospective questions for the 6 months preceding the survey. The second survey was conducted 9 months after prohibition and also included retrospective questions for the 6 months preceding the survey. 273 sets of paired data were identified. The use of BZP party pills (pparty pills obtained them from friends or from their own stockpiled supplies. The misuse of prescription drugs (p=0.02) increased over time, whereas statistically significant increases in stimulant or alcohol use were not noted. Following prohibition of piperazine-based party pills, we noted a significant reduction in the proportions of participants using them. The observed increase in the misuse of prescription medicines may relate to their perceived 'quality', or as being less 'illegal' than illicit drugs. Copyright © 2013 Elsevier B.V.

  17. A method for sorting irradiated substances according to their color

    International Nuclear Information System (INIS)

    Sawyer, Baldwin.

    1974-01-01

    Description is given of a method for isolating quartz, quartzit, glass or silicate-containing substances with known contents of aluminium. That nondestructive method comprises the step of exposing said substances to an ionizing radiation for a sufficient duration and with a sufficent intensity for developing the various colors typical of the substances containing aluminium ions. Depending on the ions associated with the aluminiums ions, the intensity of each of the developed colors corresponds to the amount of aluminium contained in the crystals. In this way, aluminium-free quartz, quartzit, glass or silicate-containing substances can be isolated if they exist in a mixture containing portions of said substances each of which has a known uniform aluminium content [fr

    2013-07-01

    An open ended coaxial cavity method for dielectric characterization of powdery substance operating at 4.5 GHz in TEM mode is presented. Classical mixing rules and electromagnetic modeling were utilized with measured effective permittivities and Q factors to determine the relative permittivity and dielectric loss tangent of different powders with ɛr up to 30. The modeling enabled determination of the correction factor for the simplified equation for the relative permittivity of an open ended coaxial resonator and mixing rules having the best correlation with experiments. SiO2, Al2O3, LTCC CT 2000, ZrO2, and La2O3 powders were used in the experiments. Based on the measured properties and Bruggeman symmetric and Looyenga mixing rules, the determined dielectric characteristics of the powders exhibited good correlation with values in the literature. The presented characterization method enabled the determination of dielectric properties of powdery substances within the presented range, and therefore could be applied to various research fields and applications where dielectric properties of powders need to be known and controlled.

    1978-01-01

    The magnetic-relaxation method is considered of the quantitative analysis of inorganic substances based on time dependence of magnetic nuclei relaxation on the quantity of paramagnetic centres in a solution. The characteristic is given of some methods of measuring nuclear magnetic relaxation times: method of weak oscillation generator and pulse methods. The effect of temperature, general solution viscosity, diamagnetic salt concentration, medium acidity on nuclear relaxation velocity is described. The determination sensitivity is estimated and the means of its increase definable concentration intervals and method selectivity are considered. The method application when studying complexing in the solution is described. A particular attention is given to the investigation of heteroligand homocentre, heterocentre and protonated complexes as well as to the problems of particle exchange of the first coordination sphere with particles from the mass of solution. The equations for equilibrium constant calculation in different systems are given. Possibilities of determining diamagnetic ions by the magnetic-relaxation method using paramagnetic indicators are confirmed by the quantitative analysis of indium, gallium, thorium and scandium in their salt solutions

  1. Advances in Statistical Methods for Substance Abuse Prevention Research

    MacKinnon, David P.; Lockwood, Chondra M.

    2010-01-01

    The paper describes advances in statistical methods for prevention research with a particular focus on substance abuse prevention. Standard analysis methods are extended to the typical research designs and characteristics of the data collected in prevention research. Prevention research often includes longitudinal measurement, clustering of data in units such as schools or clinics, missing data, and categorical as well as continuous outcome variables. Statistical methods to handle these features of prevention data are outlined. Developments in mediation, moderation, and implementation analysis allow for the extraction of more detailed information from a prevention study. Advancements in the interpretation of prevention research results include more widespread calculation of effect size and statistical power, the use of confidence intervals as well as hypothesis testing, detailed causal analysis of research findings, and meta-analysis. The increased availability of statistical software has contributed greatly to the use of new methods in prevention research. It is likely that the Internet will continue to stimulate the development and application of new methods. PMID:12940467

    During the last years, an increased misuse of doping substances in sport has been observed. The action of doping substances characterized by the stimulation of blood flow and metabolic processes is also reflected in the hair structure. In the present study it was demonstrated that optical coherent tomography is well suited for the analysis of hair parameters influenced by doping. Analyzing 20 patients, systemically treated with steroids which also represent doping substances, it was found that in all cases a significant increase in the cross-section of the hairs could be detected. The results obtained in the study are not only important for the screening of doping substances but also for medical diagnostics and control of compliance of patients.

    In this process, the decay heat from radioactive substances is removed by means of a liquid carried in the coolant loop. The liquid is partially evaporated by the decay heat. The steam is used to drive the liquid through the loop. When a static pressure level equivalent to the pressure drop in the loop is exceeded, the steam is separated from the liquid, condensed, and the condensate is reunited with the return flow of liquid for partial evaporation.

    Wang, Renqi; Gutié rrez, Leonardo A.; Ng, Siuchoon; Croue, Jean-Philippe

    2015-01-01

    A hydrophilic interaction liquid chromatography (HILIC) method was developed to measure the composition of humic substances from river, reservoir, and treated wastewater based on their physicochemical properties. The current method fractionates the humic substances into four well-defined groups based on parallel analyses with a neutral and a cationic HILIC column, using mobile phases of varied compositions and pH. The results indicate that: (i) the proportion of carboxylic acids in the humic substances from terrestrial origins is less than half of that from treated wastewater (Jeddah, KSA), (ii) a higher content of basic compounds was observed in the humic substances from treated wastewater and Ribou Reservoir (Cholet, France) than in the sample from Loire River (France), (iii) a higher percentage of hydrophobic macromolecules were found in the humic substances from Loire River than in the other samples, and (iv) humic substances of treated wastewater contained less ionic neutral compounds (i.e., pKa 5-9) than the waters from terrestrial origins. The physicochemical property disparity amongst the compounds in each humic substances sample was also evaluated. The humic substances from the lightly humic Loire river displayed the highest disparity, whereas the highly humic Suwannee river (Georgia, USA) showed the most homogeneous humic substances.

    Analysis of related substances in pharmaceutical chemicals and multi-components in traditional Chinese medicines needs bulk of reference substances to identify the chromatographic peaks accurately. But the reference substances are costly. Thus, the relative retention (RR) method has been widely adopted in pharmacopoeias and literatures for characterizing HPLC behaviors of those reference substances unavailable. The problem is it is difficult to reproduce the RR on different columns due to the error between measured retention time (t R ) and predicted t R in some cases. Therefore, it is useful to develop an alternative and simple method for prediction of t R accurately. In the present study, based on the thermodynamic theory of HPLC, a method named linear calibration using two reference substances (LCTRS) was proposed. The method includes three steps, procedure of two points prediction, procedure of validation by multiple points regression and sequential matching. The t R of compounds on a HPLC column can be calculated by standard retention time and linear relationship. The method was validated in two medicines on 30 columns. It was demonstrated that, LCTRS method is simple, but more accurate and more robust on different HPLC columns than RR method. Hence quality standards using LCTRS method are easy to reproduce in different laboratories with lower cost of reference substances.

    The method and the measuring disposition serve to localize pellets doped with Gd 2 O 3 , lying between UO 2 pellets within a reactor fuel rod. The fuel rod is penetrating a homogeneous magnetic field generated between two pole shoes. The magnetic stray field caused by the doping substances is then measured by means of Hall probes (e.g. InAs) for quantitative discrimination from UO 2 . The position of the Gd 2 O 3 -doped pellets is determined by moving the fuel rod through the magnetic field in a direction perpendicular to the homogeneous field. The measuring signal is caused by the different susceptibility of Gd 2 O 3 with respect to UO 2 . (DG) [de

    Hirshfield, J.L.; Krishnan, M.

    1986-01-01

    This invention provides a method and apparatus for separating isotopes using a plasma centrifuge; in particular, it provides a multistage method and apparatus wherein a laser-initiated vacuum arc is used to fully ionize and form a plasma of the substances to be separated. The substances to be separated are positioned in an evacuated vessel which has a longitudinal axis. A magnetic field is generated in the vessel parallel to the axis of the vessel, and a target comprised of the substances to be separated is positioned at one end of the vessel. Pulsed laser energy is focused on the substances, thereby completely ionizing at least a portion of the substances and forming a plasma. Immediately following the arrival of the laser energy, a current is passed through the substances to be separated, which causes further complete ionization. The plasma is rotated and moved from the target to the collector by the application of a magnetic field. A plurality of skimmers is positioned in the vessel between the target and the collector such that a portion of the rotating plasma strikes the skimmer and is collected thereon. The remainder of the plasma continues moving towards the collector. The material which finally strikes the collector is only a percentage of the starting material, but it is highly enriched or concentrated

    The autoradiographic methods for animals used up to the present do not make it possible to localise exactly the distribution of marked volatile molecules. The Ullberg method (1954) which we have modified (Cohen, Delassue, 1959) involves cold desiccant. The method due to Pellerin (1957) avoids this desiccant but the histological comparison of the autoradiography with the biological document itself is difficult, if not impossible. Nevertheless, we have adopted certain points in the two methods and propose the following technique for the autoradiographic study of marked volatile molecules: 1- The surface of the frozen sample to be studied is prepared using a freezing microtome. 2- The last section, which is 20 μ thick and whose histological elements are parallel to those of the block, is dried by cooling and is used as the biological reference document for the autoradiography obtained, as is indicated in 3; 3- The radiography films are applied to the frozen block at -30 deg. C. The autoradiographs correspond to the radioactivity of the volatile molecule and of its non-volatile degradation products. 4- The radiographic film is also applied to the 20 μ section previously dried at -20 deg. C. This autoradiography corresponds to the radioactivity of the non-volatile degradation products of the molecule. 5- We confirmed the absence of diffusion of the volatile molecule and of pseudo-radiographic effects (photochemical and others). This method, which has enabled us to study the distribution of a carbide, para-cymene (C 14 ) 7, macroscopically in the case of a whole mouse and microscopically on the skin of a dog, can find general applications.

    The invention relates to the extraction of radioactive isotopes from air. It refers to a method for withdrawing the radioactive substances resulting from the disintegration of radon from air, said method of the type comprising filtrating the air contaminated by the radon daughter products in a filter wetted with water in order to trap said substances in water. It is characterized in that it comprises the steps of causing the water contaminated by the radon daughter products to flow through a filtrating substance containing a non hydrosoluble granular substrate, the outer surface of which has been dried then wetted by a normally-liquid hydrocarbon, and of returning then wetted by a normally-liquid hydrocarbon, and of returning the thus filtrated water so that it wets again the air filter and entraps further radon daughter products. This can be applied to the purification of the air in uranium mines [fr

    Full Text Available One of the most important factors of successful substance abuse treatment is the early start of the same treatment. Recent selection method for identification of Croatian adolescents in the substance abuse risk that has been using drug tests from urine samples, has been simple and exact on the one hand, but on the other, has been very rare and usually guided by the pressure of parents or the court. Besides, such method presented the source of legal and ethical questions. So, the proposal of application of standardized psychological tests during systematic medical exams of Croatian adolescents at the age range of 15-22 years could help with the early detection of those adolescents who were in the substance abuse risk or already had the developed addiction problem.

    Nowadays modern requirements to achieving reliable results along with high quality of researches put mathematical analysis methods of results at the forefront. Because of this, evidence-based methods of processing experimental data have become increasingly popular in the biological sciences and medicine. Their basis is meta-analysis, a method of quantitative generalization of a large number of randomized trails contributing to a same special problem, which are often contradictory and performed by different authors. It allows identifying the most important trends and quantitative indicators of the data, verification of advanced hypotheses and discovering new effects in the population genotype. The existing methods of recognizing high molecular substances by gel electrophoresis of proteins under denaturing conditions are based on approximate methods for comparing the contrast of electrophoregrams with a standard solution of known substances. We propose a fuzzy method for modeling experimental data to increase the accuracy and validity of the findings of the detection of new proteins.

    2014-08-01

    A simple, sensitive and reproducible method was developed on ultra-performance liquid chromatography coupled with photodiode array detection for the quantitative determination of dronedarone hydrochloride (DRO) in drug substance and pharmaceutical dosage forms. The method is applicable for the quantification of related substances and assays of drug substances. Chromatographic separation was achieved on Acquity UPLC BEH C8 100 mm, 2.1 mm and 1.7 µm columns, using gradient elution within a short run time of 10.0 min. The eluted compounds were monitored at 288 nm, the flow rate was 0.5 mL/min and the column oven temperature was maintained at 40°C. The resolution of DRO and 11 impurities (potentials and by-products) was greater than 2.0 for all pairs of components. The high correlation coefficient value (>0.9995) indicates the clear correlations between the concentrations of investigated compound and their peak areas within the test ranges. The repeatability and intermediate precision, expressed by the relative standard deviation, were less than 2.5%. The accuracy and validity of the method were further ascertained by performing recovery studies via a spike method. The accuracy of the method, expressed as relative error, was satisfactory. No interference was observed from concomitant substances normally added to the tablets. DRO was subjected to the stress conditions of oxidative, acid, base, hydrolytic, thermal and photolytic degradation. DRO was found to degrade significantly in acid and base stress conditions and to remain stable in thermal, photolytic degradation, oxidative and hydrolytic conditions. The degradation products were well resolved from primary peak and its impurities, proving that the method is stability indicating. The developed method was validated as per International Conference on Harmonization guidelines with respect to specificity, limit of detection, limit of quantification, linearity, accuracy, precision, solution stability and robustness

    The method ensures the removal of radioactive substances from hard-to-decontaminate water. Before decontamination proper, ozone or chlorine is added to the water for demasking. The daughter products (oxidized radionuclides) of ozone are gaseous while the decay products of the chlorine remain in the water in the form of salts. In both cases, complex or chelate formation during the subsequent decontamination process is avoided.

    Today important chemical substances like proteins can be produced easily and in large amounts. The primary structure of proteins can be analysed automatically, however the procedure can take some months of time. A novel method, fast atom bombardment mass spectrometry (FAB-MS) in combination with enzymatic degradation not only decreases the analysis time, but gives also additional information about the primary structure. Especially for the verification of protein structures - which is important for recombinant proteins - FAB-MS is a very useful method. 40 refs., 56 figs. (P.W.)

    Full text: The method and the device [1] are intended for use as a high-sensitivity magnetic separator for different types of paramagnetic substances and materials from diamagnetic ones, for division of paramagnetic substances and materials on the magnitudes of their paramagnetic susceptibility, for division of diamagnetic substances and materials on magnitudes of their diamagnetic susceptibility. Scopes: to produce pure and super pure substances and materials in electronics, metallurgy and chemistry, separation of biological objects (red blood cells, magnetic bacteria, etc.) in biology and medicine, water treatment removing heavy metals and organic impurities, etc. The main condition for magnetic separation is the magnetic force which acts on a particle of the substance and which is proportional to the magnetic susceptibility of the substance, magnetic induction B and gradient ∇B of the applied magnetic field. Therefore, to increase the sensitivity and selectivity of magnetic separation it will be required to use the largest possible values of the magnetic induction and the gradient of a magnetic field, or their product - B∇B. The device declared in the present work includes the magnetic system such as the open domain structure, consisting of permanent magnets with magnetic anisotropy much greater than the induction of a material of magnets. However, the declared device differs from the open domain structure in that [1]: *the surface of the neighbor poles of magnets is covered with a mask made from sheets of adjustable thickness of a soft magnetic material; *the soft magnetic material of the mask is selected on the basis of the magnitudes of the induction of saturation and magnetic permeability for achievement of the required magnitude of the induction and gradient of the magnetic field; *between the sheets of the mask there is an adjustable gap located symmetrically relative to the junction line of the magnets; *the size and the form of the gap between the

    Full text: Neutron analysis method of determining element composition have found wide range of applications in industry thanks to different types of interaction of neutron with substances /1/. With the aim of widening the range of problems to be solved, on the basis of the device /2/ for determining the element content of substance, possibilities of combining the method based on the use of neutron capture gamma-ray spectrometry with other neutron methods, in particular neutron activation analysis and neutron absorption analysis were studied. In this radionuclide source ( 252 Cf) with the yield of 1,5 x 10 7 neutron/sec is used. By means of using neutron capture gamma radiation spectrometry the possibilities of determining some elements (H, B, N, S etc. ), which are not determined by very widely used method, activation analysis. These elements can be determined by both the semiconductor and scintillation detectors with parameters fitting the manufacturing requirements. And for a number of elements ( B, Cl, Cd, Sm, Gd) very high limits of determination ( up to 10- 5 %) are possible using semiconductor Ge (Li) -detectors with high resolution. Possibility of determination of some 'well' activated elements ( K, Al, Fe, Mn, Ti, Sc etc.) in samples of ore and products of their processing using the neutron-activation analysis. For 1 hour of irradiation on the experimental device quite accurate analytical peak, of these elements are obtained, allowing to determine them qualitatively. However, with decreasing neutron yield of radionuclide source it becomes more difficult to achieve the necessary parameters both in neutron capture and activation analysis. Experimental works on determination of some elements with large cross-sections of capture ( B, Cd, Sm ) by absorption of neutrons in the investigated substance, i.e. using the neutron absorption analysis method with absence of other large capture cross section elements in the samples being studied

    The knowledge of cation-humic matter interactions has a great importance in order to have a better understanding of the contribution of these substances to the possible transport of radioactive elements in the geosphere via groundwaters. The method chosen to study the formation of soluble species between lanthanides/actinides ions and humic acids from different origins is a chromatographic technique of gel filtration. This dynamic equilibrium method is based on the separation of the formed complex and the free cation by the porous packing gel. Different elements have been studied by this method: UO 2 2+ , Eu 3+ , Th 4+ and global interaction constants have been calculated. The application to transuranic elements is undertaken. (orig.)

    To analyze the relationship between utilization patterns for condoms and other contraceptive methods and the consumption of alcohol and drugs. Exploratory study based on data from a probabilistic sample of 5,040 interviewees aged 16 to 65 years living in large urban regions of Brazil in 2005. The data were collected by means of questionnaires. The chi-square automatic interaction classification tree technique was used to study the use of condoms among interviewees of both sexes and other contraceptive methods among women, at the time of the last vaginal sexual intercourse. Among young and middle-aged adults of both sexes and young men in stable relationships, condom use was less frequent among those who said they used psychoactive substances (alcohol and/or illegal drugs). The possible modulating effect of psychoactive substances on contraceptive practices among mature women seems to be more straightforward, compared to the more subtle effects observed among younger women, for whom the different social classes they belonged to seemed to play a more important role. Despite the limitations resulting from an exploratory study, the fact that this was a representative sample of the urban population of Brazil and not from vulnerable populations, reinforces the need to implement integrated public policies directed towards the general population, with regard to preventing drug consumption, alcohol abuse, sexually transmitted infections, HIV/AIDS and unwanted pregnancy and promoting sexual and reproductive health.

    2000-05-01

    The authors describe methods for work in progress to evaluate four workplace prevention and/or early intervention programs designed to change occupational norms and reduce substance abuse at a major U.S. transportation company. The four programs are an employee assistance program, random drug testing, managed behavioral health care, and a peer-led intervention program. An elaborate mixed-methods evaluation combines data collection and analysis techniques from several traditions. A process-improvement evaluation focuses on the peer-led component to describe its evolution, document the implementation process for those interested in replicating it, and provide information for program improvement. An outcome-assessment evaluation examines impacts of the four programs on job performance measures (e.g., absenteeism, turnover, injury, and disability rates) and includes a cost-offset and employer cost-savings analysis. Issues related to using archival data, combining qualitative and quantitative designs, and working in a corporate environment are discussed.

  18. Humic substances and its distribution in coffee crop under cover crops and weed control methods

    2016-08-01

    Full Text Available ABSTRACT Humic substances (HS comprise the passive element in soil organic matter (SOM, and represent one of the soil carbon pools which may be altered by different cover crops and weed control methods. This study aimed to assess HS distribution and characteristics in an experimental coffee crop area subjected to cover crops and cultural, mechanical, and chemical weed control. The study was carried out at Londrina, in the state of Paraná, southern Brazil (23°21’30” S; 51°10’17” W. In 2008, seven weed control/cover crops were established in a randomized block design between two coffee rows as the main-plot factor per plot and soil sampling depths (0-10 cm, 10-20 cm, 20-30 cm and 30-40 cm as a split-plot. HS were extracted through alkaline and acid solutions and analyzed by chromic acid wet oxidation and UV-Vis spectroscopy. Chemical attributes presented variations in the topsoil between the field conditions analyzed. Cover crop cutting and coffee tree pruning residues left on the soil surface may have interfered in nutrient cycling and the humification process. Data showed that humic substances comprised about 50 % of SOM. Although different cover crops and weed control methods did not alter humic and fulvic acid carbon content, a possible incidence of condensed aromatic structures at depth increments in fulvic acids was observed, leading to an average decrease of 53 % in the E4/E6 ratio. Humin carbon content increased 25 % in the topsoil, particularly under crop weed-control methods, probably due to high incorporation of recalcitrant structures from coffee tree pruning residues and cover crops.

    Previous investigations have shown that the yolk-sac of embryonic bird's eggs can be used to produce the following reactions: (a) reduction of sulphate to sulphite; (b) fixation of the sulphite on the carbon chain produced by the desulf-hydration of l-cysteine, with formation of l-cysteic acid; (c) decarboxylation of the l-cysteine acid into taurine. The enzymatic system which causes reaction (b) has been purified. It also acts as a catalyst in the sulphur-exchange between the cysteine and the mineral sulphide. The authors have utilized these data in preparing sulphurated substances labelled with S 35 : taurine S 35 , l-cysteine S 35 and l-cysteic acid S 35 . For each of the three, they discuss the chemical reactions involved, the methods of preparation, the experimental conditions of extraction and purity-control, together with the yields and specific activities obtained.

    Full Text Available Background: Illicit substance use is a serious social problem faced by adolescents worldwide, including adolescents in Aceh and has many negative consequences. In addition, illicit substance use does not fit with the values of Islamic teaching, and is strictly prohibited in Islam. Purpose: The aims of this paper are to determine the prevalence of illicit substance use, the stages of substance use, and types of substance used among Muslim students in senior high schools in Aceh, Indonesia. Method: Four hundred and twenty six students who met the inclusion criteria were recruited from four senior high schools in Banda Aceh by using simple random sampling, and of these, 290 returned a completed questionnaire. A self reported questionnaire was used to collect data. Result: The mean age of the subjects was 15.9 years old and the majority of them were female (68.6%. The study found that the prevalence of substance use was 2.4%with a higher number of females than males who had used illicit substances. The common substances that were used by the students were marijuana and dextromethorphon, as well as intentionally inhaled substances. Lastly, out of the students who had used illegal substances the majority was in the regular use stage (1.4%. Conclusion: This study found that substance use among Muslim students in Aceh exists, although prevalence was low. Thus, several preventive programs may be needed in Aceh not only for Muslims students who have used substances but also for students who have not use illegal substances. Keywords: Adolescents, Substance use, Muslim students, Indonesia.

  1. An ecodesign method for reducing the effects of hazardous substances in the product lifecycle

    2012-10-01

    Growing evidence on the indoor and outdoor pollution caused by the flow of man-made products urges that the content and leaching of hazardous substances from products be minimised. One of the ways to reduce the potential adverse impacts caused by these substances could be via ecodesign - i.e. through the consideration of lifecycle-related environmental aspects during the product development. The authors’ review of the existing ecodesign methods highlights the weakness of these methods in identifying and assessing the health-related and environmental impacts of hazardous substances contained in products, especially with regard to the exposure assessment. Therefore, a new, semi-quantitative screening ecodesign method applicable for different types of products has been developed. The method ranks the most severe hazards based on the classification according to the Globally Harmonised System together with the exposure evaluation as well as integrates the aspects of material efficiency. This method is suitable for use in the product development process, requiring decisions to be made based on limited information while integrating the main principles of a scientific risk assessment for chemicals. Application of the method is demonstrated with a case study on products made of plywood. The method makes it possible to identify the needs for and elaboration of ecodesign proposals, and fosters communication and information exchange throughout the supply chain.

    New Psychoactive Substances (NPS) belong to several chemical classes, including phenethylamines, piperazines, synthetic cathinones and synthetic cannabinoids. Development and validation of analytical methods for the determination of NPS both in traditional and alternative matrices is of crucial importance to study drug metabolism and to associate consumption to clinical outcomes and eventual intoxication symptoms. Among different biological matrices, hair is the one with the widest time window to investigate drug-related history and demonstrate past intake. The aim of this paper was to overview the trends of the rapidly evolving analytical methods for the determination of NPS in hair and the usefulness of these methods when applied to real cases. A number of rapid and sensitive methods for the determination of NPS in hair matrix has been recently published, most of them using liquid chromatography coupled to mass spectrometry. Hair digestion and subsequent solid phase extraction or liquid-liquid extraction were described as well as extraction in organic solvents. For most of the methods limits of quantification at picogram per milligram hair were obtained. The measured concentrations for most of the NPS in real samples were in the range of picograms of drug per milligram of hair. Interpretation of the results and lack of cut-off values for the discrimination between chronic consumption and occasional use or external contamination are still challenging. Methods for the determination of NPS in hair are continually emerging to include as many NPS as possible due to the great demand for their detection.

    Drug analysis is an imperative activity to check the quality of a drug compound. Pharmacopoeial monographs provide important information about the quality of a drug substance. The expected quality of a medicine during period of use is also explained in such monographs. Analytical tools such as spectroscopic and chromatographic methods have been developed for such investigations. We have analysed the purity of a well known anxiolytic drug; diazepam, by using liquid chromatographic (LC) technique. It was noticed that with Zorbax Eclipse XDB - C8 (4.6 x 150 mm, 5 mu m) column and recommended mobile phase comprising acetonitrile - methanol -potassium dihydrogen phosphate (22+34+44 v/v), the desired results obtained were not according the chromatograms provided by European Pharmacopeia (EP), but by using another column (ACE- 5 - C8) (4.6 x 150 mm, 5 ?m), an extra peak of diazepam degradant was obtained, which showed that by using appropriate mobile phase containing CH3CN- CH/sub 3/OH- KH/sub 2/PO/sub 4/ (20+32+48 v/v), the better results can be achieved. The mean retention time for diazepam analysis was 2.9 minutes. (author)

    To systematically review the literature on contraceptive use by women with opioid and other substance use disorders in order to estimate overall contraceptive use and to examine method choice given the alarmingly high rate of unintended pregnancy in this population. Pubmed (1948-2014) and PsycINFO (1806-2014) databases were searched for peer-reviewed journal articles using a systematic search strategy. Only articles published in English and reporting contraceptive use within samples of women with opioid and other substance use disorders were eligible for inclusion. Out of 580 abstracts reviewed, 105 articles were given a full-text review, and 24 studies met the inclusion criteria. The majority (51%) of women in these studies reported using opioids, with much smaller percentages reporting alcohol and cocaine use. Across studies, contraceptive prevalence ranged widely, from 6%-77%, with a median of 55%. Results from a small subset of studies (N=6) suggest that women with opioid and other substance use disorders used contraception less often than non-drug-using comparison populations (56% vs. 81%, respectively). Regarding method choice, condoms were the most prevalent method, accounting for a median of 62% of contraceptives used, while use of more effective methods, especially implants and intrauterine devices (IUDs), was far less prevalent 8%. Women with opioid and other substance use disorders have an unmet need for contraception, especially for the most effective methods. Offering contraception services in conjunction with substance use treatment and promoting use of more effective methods could help meet this need and reduce unintended pregnancy in this population.

    Over 1.6 million adolescents in the United States meet criteria for substance use disorders (SUDs). While there are promising treatments for SUDs, adolescents respond to these treatments differentially in part based on the setting in which treatments are delivered. One way to address such individualized response to treatment is through the development of adaptive interventions (AIs): sequences of decision rules for altering treatment based on an individual's needs. This protocol describes a project with the overarching goal of beginning the development of AIs that provide recommendations for altering the setting of an adolescent's substance use treatment. This project has three discrete aims: (1) explore the views of various stakeholders (parents, providers, policymakers, and researchers) on deciding the setting of substance use treatment for an adolescent based on individualized need, (2) generate hypotheses concerning candidate AIs, and (3) compare the relative effectiveness among candidate AIs and non-adaptive interventions commonly used in everyday practice. This project uses a mixed-methods approach. First, we will conduct an iterative stakeholder engagement process, using RAND's ExpertLens online system, to assess the importance of considering specific individual needs and clinical outcomes when deciding the setting for an adolescent's substance use treatment. Second, we will use results from the stakeholder engagement process to analyze an observational longitudinal data set of 15,656 adolescents in substance use treatment, supported by the Substance Abuse and Mental Health Services Administration, using the Global Appraisal of Individual Needs questionnaire. We will utilize methods based on Q-learning regression to generate hypotheses about candidate AIs. Third, we will use robust statistical methods that aim to appropriately handle casemix adjustment on a large number of covariates (marginal structural modeling and inverse probability of treatment weights

    With the increasing use of unregulated dietary supplements, athletes are at continued risk from adverse medical events and inadvertent doping. A review of Clinical Key, MEDLINE, and PubMed databases from 2012 to 2017 was performed using search terms, including dietary supplement, contamination, doping in athletes, inadvertent doping, and prohibited substances. The references of pertinent articles were reviewed for other relevant sources. Clinical review. Level 3. Poor manufacturing processes and intentional contamination with many banned substances continue to occur in dietary supplements sold in the United States. Certain sectors, such as weight loss and muscle-building supplements, pose a greater threat because they are more likely to be contaminated. Athletes will continue to be at risk for adverse events and failed doping tests due to contaminated dietary supplements until legislation changes how they are regulated. In the interim, there are several steps that can be taken to mitigate this risk, including improved education of medical staff and athletes and use of third party-certified products.

    A method and device for the detection of low-level harmful substances in a large volume of fluid comprising using a concentrator system to produce a retentate and analyzing the retentate for the presence of at least one harmful substance. The concentrator system performs a method comprising pumping at least 10 liters of fluid from a sample source through a filter. While pumping, the concentrator system diverts retentate from the filter into a container. The concentrator system also recirculates at least part of the retentate in the container again through the filter. The concentrator system controls the speed of the pump with a control system thereby maintaining a fluid pressure less than 25 psi during the pumping of the fluid; monitors the quantity of retentate within the container with a control system, and maintains a reduced volume level of retentate and a target volume of retentate.

  16. Security and health protection during the transport of hazardous substances

    Benkovic, Z.; Bobic, V.

    2009-01-01

    The introduction of this work describes the legal regulations which regulate the conditions and method of the transport of hazardous substances, necessary documentation for storage, forwarding and transport. Hazardous substances are defined and classified according to the ADR. The necessary security measures which are taken for the transport of particular types of hazardous substances are mentioned. Marking and labeling of vehicles for the transport of hazardous substances (plates and lists of hazards), packing and marking of packaging is important. The safety measures which are taken at the filling stations of combustible liquids as well as places specially organized for filling, prohibitions and limitations and necessary transport documentation are mentioned. It is visible from the above mentioned that the activity of the whole security chain is necessary and depends on the good knowledge of basic characteristics and features of substances. All the participants in the security chain have to be familiar with and consistently obey the legal regulations. The manufacturer must know the features of the hazardous substance, supervisory services must be acquainted with the threat and potential danger. The hauler and intervention forces must, in case of accidents and damage, be familiar with the emergency procedures in case of accidents and act properly regarding the threatening dangerous substance.(author)

    Object: To separate waste liquid resulting from washing and which contains a radioactive substance and surface active agent into high purity water and a solid waste substance containing a small quantity of surface active agent. Structure: To waste liquid from a waste liquid tank is added a pH adjusting agent for adjusting the pH to 5.5, and the resultant liquid is sent to an agglomeration reaction tank, in which an inorganic agglomerating agent is added to the waste liquid to cause a major proportion of the radioactive substance and surface active agent to form flocks produced through agglomeration. Then, the waste liquid is sent from the agglomeration reaction tank to a froth separation tank, to which air is supplied through a perforated plate to cause frothing. The over-flowing liquid is de-frothed, and then the insoluble matter is separated as sludge, followed by hydroextraction and drying for solidification. The treated liquid extracted from a froth separation tank is sent to an agglomerating agent recovery tank for separation of the agglomeration agent, and then the residual surface active agent is removed by adsorption in an active carbon adsorption tower, followed by concentration by evaporation in an evaporating can. The concentrated liquid is extracted and then solidified with cement or asphalt. (Kamimura, M.)

    In this paper separation of granisetron and its two related substances in HILIC mode is presented. Separation was done on silica column derivatized with sulfoalkylbetaine groups (ZIC-HILIC). Firstly, retention mechanisms were assessed whereby retention factors of substances were followed in wide range of acetonitrile content (80-97%), at constant concentration of aqueous buffer (10mM) as well as at constant pH value of 3.0. Further, in order to developed optimal HILIC method, Design of Experiments (DoE) methodology was applied. For optimization full factorial design 3(2) was employed. Influence of acetonitrile content and ammonium acetate concentration were investigated while pH of the water phase was kept at 3.3. Adequacy of obtained mathematical models was confirmed by ANOVA. Optimization goals (α>1.15 and minimal run time) were accomplished with 94.7% of acetonitrile in mobile phase and 70 mM of ammonium acetate in water phase. Optimal point was in the middle of defined Design Space. In the next phase, robustness was experimetally tested by Rechtschaffen design. The investigated factors and their levels were: acetonitrile content (±1%), ammonium acetate molarity in water phase (±2 mM), pH value of water phase (±0.2) and column temperature (±4 °C). The validation scope included selectivity, linearity, accuracy and precision as well as determination of limit of detection (LOD) and limit of quantification (LOQ) for the related substances. Additionally, the validation acceptance criteria were met in all cases. Finally, the proposed method could be successfully utilized for estimation of granisetron HCl and its related substances in tablets and parenteral dosage forms, as well as for monitoring degradation under various stress conditions.

    Directory of Open Access Journals (Sweden)

    2004-05-01

    Full Text Available Addicts to alcohol and other substances changing the mood and behavior attempt to stop their addiction and avoid its relapse because they suffer mental and physical problems, they are under the pressure of family members, employer and other individuals who influence over their life as well as negative effects of drug addiction on their performance in family, work and social relations. Since drug addicts experience physical pain when they are not using drugs, they refer, at first, to physicians and then to psychiatrists. Although emerging and applying non-medical and non-pharmaceutical approaches models is not too old, arising various addictive drugs and increasing the number of drug addicts as well as individual/social destructive consequences of drug addiction have caused that psychiatrists, psychologists and social workers to represent various non-pharmaceutical theories, models, methods and guidelines based on the conditions of their clients and their clinical experiences. The present article attempts to identify the reasons of drug addiction tendency, consumption patterns, models, theories of addiction to substances changing the mood and behavior, various methods of drug treatment, effective methods in drug addiction counseling and non-medical and non-pharmaceutical methods to give up drug addiction by using recent research findings. On this basis, the most effective methods to help those who suffer from alcohol and other drugs abuse and dependency are studied.

    1981-01-01

    The discovery of different kinds of interactions between solids and fotonic, respectively electronic and ionic beams, leads to the development of many new, very sensitive, physical methods for the study of solids. This monograph tries to present some of these methods, useful in compositional analysis, in the study of electronic properties and of the surface processes of solid substances. This is done from the point of view both of physical phenomena underlying them and of the information obtainable with such methods. But the whole monograph is limited only to the methods based on the electronic properties of the elements existing in the solid probes studied and this paper presents only those of them in which the detected beam is an electronic one, like: ELS, DAPS, ILS, AES, AEAPS, INS, TSS, XPS and UPS.

    Explanations based in attribution theory claim that strong external controls such as parental restrictiveness and punishment undermine moral internalization. In contrast, 3 studies provide evidence that parental punishment does socialize morality, but of a particular sort: a morality focused on prohibitions (i.e., proscriptive orientation) rather than positive obligations (i.e., prescriptive orientation). Study 1 found young adults' accounts of parental restrictiveness and punishment activated their sensitivity to prohibitions and predicted a proscriptive orientation. Consistent with the greater potency of temptations for proscriptively oriented children, as well as past research linking shame to proscriptive morality, Study 2 found that restrictive parenting was also associated with greater suppression of temptations. Finally, Studies 3A and 3B found that suppressing these immoral thoughts is paradoxically harder for those with strong proscriptive orientations; more specifically, priming a proscriptive (versus prescriptive) orientation and inducing mental suppression of "immoral" thoughts led to the most ego depletion for those with restrictive parents. Overall, individuals who had restrictive parents had the lowest self-regulatory ability to resist their "immoral" temptations after prohibitions were activated. In contrast to common attributional explanations, these studies suggest that harsh external control by parents does not undercut moral socialization but rather undermines individuals' ability to resist temptation.

    2004-07-13

    Air is sampled at a rate in excess of 100 L/min, preferably at 200-300 L/min, so as to collect therefrom a substantial fraction, i.e., at least 20%, preferably 60-100%, of airborne particulates. A substance of interest (analyte), such as lead, is rapidly solubilized from the the collected particulates into a sample of liquid extractant, and the concentration of the analyte in the extractant sample is determined. The high-rate air sampling and particulate collection may be effected with a high-throughput filter cartridge or with a recently developed portable high-throughput liquid-absorption air sampler. Rapid solubilization of lead is achieved by a liquid extractant comprising 0.1-1 M of acetic acid or acetate, preferably at a pH of 5 or less and preferably with inclusion of 1-10% of hydrogen peroxide. Rapid determination of the lead content in the liquid extractant may be effected with a colorimetric or an electroanalytical analyzer.

Some analytical method performance characteristics were investigated, namely, the repeatability, the accuracy and the detection limit of determination. The results show that the P&T technique is--as expected--more sensitive than the static headspace, thus it can be used for the determination of residual solvents pertaining to the ICH Class 1 group. It was found that it could be an alternative sample preparation method besides the static headspace (HS) method.

    We have studied two methods for pyrogenic substances detection. We used: the hyperthermic action of these substances after injection in Rabbit, and the gelation reaction of a Limulus amebocytes lysate. To apply these two methods of pyrogenic substances detection to the radiopharmaceutical preparations, we have conceived and designed a material allowing their handling in compliance with the radioactive safety norms. We have compared the sensitivity, reliability and reproducibility of these methods, one based on gelation of Limulus amebocytes lysate in presence of endotoxins, the other on the hyperthermic action of these same endotoxins in the rabbit when injected intravenously or through the suboccipital route. The discussion of the results obtained, shows that the method using the Limulus amebocytes lysate is more sensitive, less expansive and less dangerous. This method particulary well adapted to the control of radiopharmaceutical preparations, brings an additional security to the patients for whom these products are destined [fr

    . This study presents a rigorous and critical assessment of existing physical and chemical EPS extraction methods applied to mixed-culture biomass samples (nitrifying, nitritation-anammox, and activated sludge biomass). A novel fluorescence-based method was developed and calibrated to quantify the lysis...... potential of different EPS extraction protocols. We concluded that commonly used methods to assess cell lysis (DNA concentrations or G6PDH activities in EPS extracts) do not correlate with cell viability. Furthermore, we discovered that the presence of certain chemicals in EPS extracts results in severe...... underestimation of protein and carbohydrate concentrations by using standard analytical methods. Keeping both maximum EPS extraction yields and minimal biomass lysis as criteria, it was identified a sonication-based extraction method as the best to determine and compare tightly-bound EPS fractions in different...

    Objective Information on factors associated with suicide among young individuals in Ireland is limited. The aim of this study was to identify socio-demographic characteristics and circumstances of death associated with age among individuals who died by suicide. Methods The study examined 121 consecutive suicides (2007–2012) occurring in the southern eastern part of Ireland (Cork city and county). Data were obtained from coroners, family informants, and health care professionals. A comparison was made between 15-24-year-old and 25-34-year-old individuals. Socio-demographic characteristics of the deceased, methods of suicide, history of alcohol and drug abuse, and findings from toxicological analysis of blood and urine samples taken at post mortem were included. Pearson’s χ2 tests and binary logistic regression analysis were performed. Results Alcohol and/or drugs were detected through toxicological analysis for the majority of the total sample (79.5%), which did not differentiate between 15-24-year-old and 25-34-year-old individuals (74.1% and 86.2% respectively). Compared to 25-34-year-old individuals, 15-24-year-old individuals were more likely to engage in suicide by hanging (88.5%). Younger individuals were less likely to die by intentional drug overdose and carbon monoxide poisoning compared to older individuals. Younger individuals who died between Saturday and Monday were more likely to have had alcohol before dying. Substance abuse histories were similar in the two age groups. Conclusion Based on this research it is recommended that strategies to reduce substance abuse be applied among 25-34-year-old individuals at risk of suicide. The wide use of hanging in young people should be taken into consideration for future means restriction strategies. PMID:27898722

    Background Substance use disorders (SUDs), which encompass alcohol and drug use disorders (AUDs, DUDs), constitute a major public health challenge among US veterans. SUDs are among the most common and costly of all health conditions among veterans. Objectives This study sought to examine the epidemiology of SUDs among US veterans, compare the prevalence of SUDs in studies using diagnostic and administrative criteria assessment methods, and summarize trends in the prevalence of SUDs reported in studies sampling US veterans over time. Methods Comprehensive electronic database searches were conducted. A total of 3,490 studies were identified. We analyzed studies sampling US veterans and reporting prevalence, distribution, and examining AUDs and DUDs. Results Of the studies identified, 72 met inclusion criteria. The studies were published between 1995 and 2013. Studies using diagnostic criteria reported higher prevalence of AUDs (32% vs. 10%) and DUDs (20% vs. 5%) than administrative criteria, respectively. Regardless of assessment method, both the lifetime and past year prevalence of AUDs in studies sampling US veterans has declined gradually over time. Conclusion The prevalence of SUDs reported in studies sampling US veterans are affected by assessment method. Given the significant public health problems of SUDs among US veterans, improved guidelines for clinical screening using validated diagnostic criteria to assess AUDs and DUDs in US veteran populations are needed. Scientific Significance These findings may inform VA and other healthcare systems in prevention, diagnosis, and intervention for SUDs among US veterans. PMID:26693830

    This study aimed to devise a method for prioritizing hazardous chemicals for further regulatory action. To accomplish this objective, we chose appropriate indicators and algorithms. Nine indicators from the Globally Harmonized System of Classification and Labeling of Chemicals were used to identify categories to which the authors assigned numerical scores. Exposure indicators included handling volume, distribution, and exposure level. To test the method devised by this study, sixty-two harmful substances controlled by the Occupational Safety and Health Act in Korea, including acrylamide, acrylonitrile, and styrene were ranked using this proposed method. The correlation coefficients between total score and each indicator ranged from 0.160 to 0.641, and those between total score and hazard indicators ranged from 0.603 to 0.641. The latter were higher than the correlation coefficients between total score and exposure indicators, which ranged from 0.160 to 0.421. Correlations between individual indicators were low (−0.240 to 0.376), except for those between handling volume and distribution (0.613), suggesting that each indicator was not strongly correlated. The low correlations between each indicator mean that the indicators and independent and were well chosen for prioritizing harmful chemicals. This method proposed by this study can improve the cost efficiency of chemical management as utilized in occupational regulatory systems. PMID:25419874

    A capillary gas chromatography method with a short run time, using a flame ionization detector, has been developed for the quantitative determination of trace level analysis of mesityl oxide and diacetone alcohol in the atazanavir sulfate drug substance. The chromatographic method was achieved on a fused silica capillary column coated with 5% diphenyl and 95% dimethyl polysiloxane stationary phase (Rtx-5, 30 m x 0.53 mm x 5.0 µm). The run time was 20 min employing programmed temperature with a split mode (1:5) and was validated for specificity, sensitivity, precision, linearity, and accuracy. The detection and quantitation limits obtained for mesityl oxide and diacetone alcohol were 5 µg/g and 10 µg/g, respectively, for both of the analytes. The method was found to be linear in the range between 10 µg/g and 150 µg/g with a correlation coefficient greater than 0.999, and the average recoveries obtained in atazanavir sulfate were between 102.0% and 103.7%, respectively, for mesityl oxide and diacetone alcohol. The developed method was found to be robust and rugged. The detailed experimental results are discussed in this research paper.

    Jahnke, Annika; Barber, Jonathan L.; Jones, Kevin C.; Temme, Christian

    A method intercomparison study of analytical methods for the determination of neutral, volatile polyfluorinated alkyl substances (PFAS) was carried out in March, 2006. Environmental air samples were collected in triplicate at the European background site Mace Head on the west coast of Ireland, a site dominated by 'clean' westerly winds coming across the Atlantic. Extraction and analysis were performed at two laboratories active in PFAS research using their in-house methods. Airborne polyfluorinated telomer alcohols (FTOHs), fluorooctane sulfonamides and sulfonamidoethanols (FOSAs/FOSEs) as well as additional polyfluorinated compounds were investigated. Different native and isotope-labelled internal standards (IS) were applied at various steps in the analytical procedure to evaluate the different quantification strategies. Field blanks revealed no major blank problems. European background concentrations observed at Mace Head were found to be in a similar range to Arctic data reported in the literature. Due to trace-levels at the remote site, only FTOH data sets were complete and could therefore be compared between the laboratories. Additionally, FOSEs could partly be included. Data comparison revealed that despite the challenges inherent in analysis of airborne PFAS and the low concentrations, all methods applied in this study obtained similar results. However, application of isotope-labelled IS early in the analytical procedure leads to more precise results and is therefore recommended.

    Full Text Available Background/Aim. Saliva represents an alternative specimen for substances abuse determination in toxicology. Hence, the aim of this study was to optimize a method for saliva specimen preparation for heroin metabolites, morphine and 6-monoacetylmorphine (6-mam, and codeine determination by liquid chromatography-mass spectrometry (LC/MS, and to apply this method on saliva samples taken from the patients. Methods. Saliva specimen was prepared using liqiud/liquid extraction of morphine, codeine and 6- mam by mixture of chloroform and isopropanol (9 : 1; v/v. Extracts were analysed by HPLC/MS technique: separation column Waters Spherisorb® 5 μm, ODS2, 4.6 × 100 mm; mobile phase: ammonium acetate : acetonitile (80 : 20; v/v, mobile phase flow rate 0.3 mL/min; mass detection range: 100-400 m/z. Regression and correlation analyses were performed with the probalility level of 0.05. Concentrations of morphine, codeine and 6-mam were determined in saliva samples of the patients with “opiates” in urine identified by the test strips. Results. Calibration for each analysed substance was done in the concentration range from 0.1 to 1 mg/L and the coefficient of correlation was R2 > 0.99. We obtained following calibration curves: y = 385531x + 14584; y = 398036x + 31542; and y = 524162x - 27105, for morphine, codeine and 6-mam, respectively. Recovery for morphine and codeine determination was 99%, while for 6- mam it was 94%. Limits of detection and quantification of a proposed method were 0.01 mg/L and 0.05 mg/L, respectively. Concentration of morphine in the saliva of the heroin users ranged between 0.54 and 5.82 mg/L, concentration of codeine between 0.05 and 5.33, and 6-mam between 0.01 and 0.68 mg/L. A statistically significant correlation between codeine and 6-mam concentrations was obtained. Conclusion. A proposed HPLC/MS method for morphine, codeine and 6-mam determination in saliva is accurate, simple, cheap and suitable for routine analysis and

    The use of triphenyltin (TPT) and tributyltin (TBT) in some household products is banned by "Act on the Control of Household Products Containing Harmful Substances" in Japan. To revise the official analytical method, the method for detecting these organotin compounds was examined in six laboratories using a textile product, water-based adhesive, oil-based paint, which contained known amounts of TPT and TBT (0.1, 1.0, 10 μg/g). TPT and TBT were measured by GC-MS after ethyl-derivation with sodium tetraethylborate. The TBT recoveries in the samples were 70-120%. The TPT recoveries in the water-based adhesive samples were 80-110%, while its concentrations in the textile product and oil-based paint samples decreased because of dephenylation during storage. However, the precision of the method examined was satisfactory because most coefficients of variation for TPT and TBT in the samples were less than 10%. Furthermore, the revised method was able to detect concentrations lower than the officially regulated value. However, the sample matrix and the condition of analytical instrument might affect the estimated TPT and TBT concentrations. Therefore, the revised method may not be suitable for quantitative tests; rather, it can be employed to judge the acceptable levels of these organotin compounds by comparing the values of control sample containing regulated amounts of TPT and TBT with those for an unknown sample, with deuterated TPT and TBT as surrogate substances. It is desirable that TPT in textile and oil-based paint samples are analyzed immediately after the samples obtained because of the decomposition of TPT.

    The method invented is especially for the recovery of uranium or other heavy metals too from seawater. The slight concentration of uranium in seawater sofar has not been worthwhile for a large technical recovery, especially as the hitherto known or proposed methods are mostly of an adsorption nature and the necessary equipment due to considerable disadvantages (such as e.g. too high a flow resistance with solid adsorber beds; too great an abrasion due to uncontrolled whirling motion of the adsorber particles; only discontinuous operation possible etc.) cannont be economically justified. In the method described here, a vertical upward flow through the adsorber bed is stabilized and made uniform before entering the bed by a special device (grid, sieve or holed plate) with about half the flow resistance compared to the adsorber bed, and is then slowed down uniformly by the enlarged cross-section like a diffusor. The adsorber particles are distributed uniformly over the flow cross-section kept in suspension for as long as the essential influencing parameters (weight, particle shape, flow rate etc.) experience no change. The gradual charging of the adsorber particles with heavy metal taken up from the solution and the thus involved gain in weight and the simultaneously increasing relative sinking rate cause a slow passage of the particles from the inlet to the outlet. Entrance and removal may go on continuously. (RB) [de

  14. Method and apparatus for imaging substances in biological samples by nuclear magnetic resonance

    International Nuclear Information System (INIS)

    Shaw, D.

    1984-01-01

    A method of determining the distribution of non-proton nuclei having a magnetic moment in a biological sample is described. It comprises subjecting the sample to a magnetic field, irradiating the sample with RF radiation at a proton magnetic resonance frequency and deriving a first NMR signal, indicative of electromagnetic absorption of the sample at the proton magnetic resonance frequency. A second such NMR signal at the proton resonance frequency is then derived from the sample in the presence of RF radiation at the nuclear magnetic resonance frequency of the non-proton nuclei so as to decouple protons in the sample from the non-proton nuclei. By applying an imaging technique, an image indicative of the spatial variation of the difference between the first and second signals can be produced. Imaging may be performed on the difference between the two NMR signals, or on each NMR signal followed by subtraction of the images. The method can be used to trace how a 13 C-labelled material introduced into a patient, and its breakdown products, become distributed. (author)

    A validated specific stability-indicating reverse-phase liquid chromatographic method was developed for the quantitative determination of Ambrisentan as well as its related substances in bulk samples, pharmaceutical dosage forms in the presence of degradation products and its related impurities. Forced degradation studies were performed on bulk samples of Ambrisentan as per the ICH-prescribed stress conditions using acid, base, oxidative, thermal stress and photolytic degradation to show the stability-indicating power of the LC method. Significant degradation in acidic, basic stress conditions was observed and no degradation was observed in other stress conditions. The chromatographic method was optimized using the samples generated from the forced degradation studies and the impurity-spiked solution. Good resolution between the peaks corresponds to Ambrisentan-related impurities and degradation products from the analyte were achieved on a SunFire C18 column using a mobile phase consisting of a mixture of potassium dihydrogen orthophosphate at a pH adjusted to 2.5 with ortho-phosphoric acid in water and a mixture of acetonitrile:methanol using a simple linear gradient. The detection was carried out at 225 nm. The limit of detection and the limit of quantification for the Ambrisentan and its related impurities were established. The stressed test solutions were assayed against the qualified working standard of Ambrisentan and the mass balance in each case was between 98.9 and 100.3%, indicating that the developed LC method was stability indicating. Validation of the developed LC method was carried out as per the ICH requirements. The developed method was found to be suitable to check the quality of bulk samples of Ambrisentan at the time of batch release and also during its storage (long-term and accelerated stability). © The Author [2013].

    The purpose of this study was to evaluate a pragmatic laboratory method to provide a technique for developing incontinence products better able to reduce malodor when used in the clinical setting. Bacterial growth and bacterially formed ammonia in disposable absorbent incontinence products was measured by adding synthetic urine inoculated with bacteria to test samples cut from the crotch area of the product. The inhibitory effect's of low pH (4.5 and 4.9) and 3 antimicrobial substances-chlorhexidine, polyhexamethylene biguanide (PHMB), and thymol-at 2 concentrations each, were studied. From the initial inocula of 3.3 log colony-forming units per milliliter (cfu/mL) at baseline, the bacterial growth of the references increased to 5.0 to 6.0 log cfu/mL at 6 hours for Escherichia coli, Proteus mirabilis, and Enterococcus faecalis. At 12 hours there was a further increase to 7.0 to 8.9 log cfu/mL. Adjusting the pH of the superabsorbent in the incontinence product from 6.0 to pH 4.5 and pH 4.9 significantly (P disposable absorbent products to inhibit bacterial growth and ammonia production. This technique, we describe, provides a pragmatic method for assessing the odor-inhibiting capacity of specific incontinence products.

    An alternative to the often cumbersome and time-consuming risk assessments of chemical substances could be more reliable and advanced priority setting methods. An elaboration of the simple scoring methods is provided by Hasse Diagram Technique (HDT) and/or Multi-Criteria Analysis (MCA). The present study provides an in depth evaluation of HDT relative to three MCA techniques. The new and main methodological step in the comparison is the use of probability concepts based on mathematical tools such as linear extensions of partially ordered sets and Monte Carlo simulations. A data set consisting of 12 High Production Volume Chemicals (HPVCs) is used for illustration. It is a paradigm in this investigation to claim that the need of external input (often subjective weightings of criteria) should be minimized and that the transparency should be maximized in any multicriteria prioritisation. The study illustrates that the Hasse diagram technique (HDT) needs least external input, is most transparent and is least subjective. However, HDT has some weaknesses if there are criteria which exclude each other. Then weighting is needed. Multi-Criteria Analysis (i.e. Utility Function approach, PROMETHEE and concordance analysis) can deal with such mutual exclusions because their formalisms to quantify preferences allow participation e.g. weighting of criteria. Consequently MCA include more subjectivity and loose transparency. The recommendation which arises from this study is that the first step in decision making is to run HDT and as the second step possibly is to run one of the MCA algorithms.

    Several new psychoactive substances (NPS) have reached the illegal drug market in recent years, and ecstasy-like tablets are one of the forms affected by this change. Cathinones and tryptamines have increasingly been found in ecstasy-like seized samples as well as other amphetamine type stimulants. A presumptive method for identifying different drugs in seized ecstasy tablets (n=92) using ATR-FTIR (attenuated total reflectance - Fourier transform infrared spectroscopy) and PLS-DA (partial least squares discriminant analysis) was developed. A hierarchical strategy of sequential modeling was performed with PLS-DA. The main model discriminated four classes: 5-MeO-MIPT, methylenedioxyamphetamines (MDMA and MDA), methamphetamine, and cathinones. Two submodels were built to identify drugs present in MDs and cathinones classes. Models were validated through the estimate of figures of merit. The average reliability rate (RLR) of the main model was 96.8% and accordance (ACC) was 100%. For the submodels, RLR and ACC were 100%. The reliability of the models was corroborated through their spectral interpretation. Thus, spectral assignments were performed by associating informative vectors of each specific modeled class to the respective drugs. The developed method is simple, fast, and can be applied to the forensic laboratory routine, leading to objective results reports useful for forensic scientists and law enforcement.

    This study examined reasons for substance abuse and evaluated the effectiveness of substance treatment programs in Malaysia through interviews with rehab patients and staff. Substance rehab patients (aged 18–69 years; n = 30) and staff (ages 30–72 years; n = 10) participated in semi-structured interviews covering a range of topics, including family and peer relationships, substance use and treatment history, factors for substance use and relapse, motivation for entering treatment, work experience, job satisfaction, treatment evaluation, and patient satisfaction. Most patients did not demonstrate the substance progression trend and had normal family relationships. Most patients reported having peers from normal family backgrounds as well. Various environmental and personal factors was cited as contributing to substance abuse and relapse. There was no significant difference between patient and staff program evaluation scores although the mean score for patients was lower. A holistic treatment approach with a combination of cognitive–behavioral, medical, social, and spiritual components was favored by patients. Suggestions for improving existing programs include better tailoring treatment to individual needs, and providing more post-treatment group support. PMID:27303313

    Natural organic matter (NOM) from the Han River, Korea was fractionated into humic and non-humic fractions by absorbing onto XAD-7HP, and these fractions were analyzed using UV-absorption, and for dissolved organic C (DOC). The humic fraction (i.e. humic substances; HS) was extracted and its characteristics were compared to commercial humic materials using various spectroscopic methods such as Fourier transform infrared (FT-IR), proton nuclear magnetic resonance ( 1 H-NMR) and fluorescence spectroscopy. The humic fraction as organic C was 47.0% on the average, however, a rainfall event brought a higher humic fraction into Han River water. The molar ratios of H/C and O/C in the HS from Han River water (HRHS) were 1.40 and 0.76, respectively, and the ratio of aliphatic to aromatic protons in the HS (P Al /P Ar ratio) was 5.8. Aromaticity and humification degree (i.e., degree of condensation) of HRHS were relatively lower than those from other humic materials, while the portion of oxygenated functional groups was relatively higher. FT-IR, 1 H-NMR and fluorescence spectroscopy showed distinct differences between HRHS and the commercial humic materials. Commercial humic materials are not representative of HS extracted from Han River water. The fluorescence spectra, relatively simple measurements, were found to be most useful as fingerprints for humic materials from particular sources

    There is growing awareness that students’ experiences of stress may impede academic success, compromise mental health, and promote substance use. We examined these factors in an under-studied population, private/independent high school students, using a multi-method (qualitative and quantitative), iterative data collection and analytic process. We first conducted qualitative interviews with faculty and staff at a number of highly competitive private schools, followed by an anonymous quantitative survey with 128 11th grade students from two of these settings. We then conducted a qualitative exploration of the quantitative results with a subset of students. Next, a set of Expert Panel members participated in qualitative interviews to reflect on and interpret study findings. Overall, we found students experienced high levels of chronic stress, particularly in relation to academic performance and the college admissions process. While students described a range of effective, adaptive coping strategies, they also commonly internalized these serious pressures and turned to alcohol and drugs to cope with chronic stress, although not typically at problematic levels. We discuss study implications for both schools and families derived from the Expert Panel. PMID:26257685

    Dietary supplements and chemical agents have been used for a number of decades among athletes striving to achieve increased strength and performance. This has led to a huge, growing market for the food supplement industry. The latter's products are classified as 'foods' rather than drugs and are therefore free of the stringent requirements for registration of pharmaceuticals, i.e. no safety and efficacy data are required prior to registration. During the past decade, some dietary supplements ...

    There has been an immense amount of visibility of doping issues on the international stage over the past 12 months with the complexity of doping controls reiterated on various occasions. Hence, analytical test methods continuously being updated, expanded, and improved to provide specific, sensitive, and comprehensive test results in line with the World Anti-Doping Agency's (WADA) 2016 Prohibited List represent one of several critical cornerstones of doping controls. This enterprise necessitates expediting the (combined) exploitation of newly generated information on novel and/or superior target analytes for sports drug testing assays, drug elimination profiles, alternative test matrices, and recent advances in instrumental developments. This paper is a continuation of the series of annual banned-substance reviews appraising the literature published between October 2015 and September 2016 concerning human sports drug testing in the context of WADA's 2016 Prohibited List.

    As with many Indigenous groups around the world, Aboriginal communities in Canada face significant challenges with trauma and substance use. The complexity of symptoms that accompany intergenerational trauma and substance use disorders represents major challenges in the treatment of both disorders. There appears to be an underutilization of substance use and mental health services, substantial client dropout rates, and an increase in HIV infections in Aboriginal communities in Canada. The aim of this paper is to explore and evaluate current literature on how traditional Aboriginal healing methods and the Western treatment model "Seeking Safety" could be blended to help Aboriginal peoples heal from intergenerational trauma and substance use disorders. A literature search was conducted using the keywords: intergenerational trauma, historical trauma, Seeking Safety, substance use, Two-Eyed Seeing, Aboriginal spirituality, and Aboriginal traditional healing. Through a literature review of Indigenous knowledge, most Indigenous scholars proposed that the wellness of an Aboriginal community can only be adequately measured from within an Indigenous knowledge framework that is holistic, inclusive, and respectful of the balance between the spiritual, emotional, physical, and social realms of life. Their findings indicate that treatment interventions must honour the historical context and history of Indigenous peoples. Furthermore, there appears to be strong evidence that strengthening cultural identity, community integration, and political empowerment can enhance and improve mental health and substance use disorders in Aboriginal populations. In addition, Seeking Safety was highlighted as a well-studied model with most populations, resulting in healing. The provided recommendations seek to improve the treatment and healing of Aboriginal peoples presenting with intergenerational trauma and addiction. Other recommendations include the input of qualitative and quantitative

  8. Sampling and analytical methods for assessing the levels of organic pollutants in the atmosphere: PAH, phthalates and psychotropic substances: a short review.

    This short review presents the procedures used to monitor PAHs, phthalates and psychotropic substances in the air, and the results of some measurements made in Italy and abroad. Organic contaminants are characterized by a variety of physical and chemical properties, including aggregation phase, concentration level, and life time. This variety widens the spectrum of procedures developed to assess their occurrence in the environment and biota, but prevents the complete speciation of the "organic fraction" of air, waters and particulates, and attention is paid to a few substances. The progress in health sciences stimulates the concern on contaminants and the development of new instrumental apparatuses and methods; new chemicals are continuously identified or recognized as capable of injuring the environment and organisms. Persistent organic pollutants and persistent biologically active toxicants are subject to regulation and extensively measured by means of standard procedures. For instance, polycyclic aromatic hydrocarbons, polychlorobiphenyls and polychlorodibenzodioxins are recovered from air through phase partition, thermal desorption or solvent extraction, then separated and detected through GC-MS or HPLC-MS procedures. By contrast, dedicated methods must be still optimized to monitor candidates or possible candidates as emerging organic pollutants, e.g. phthalates, flame retardants and perfluoroalkanes. Also, psychotropic substances appear of potential concern. Legal and illicit substances are commonly detected in the urban air besides waste and surface waters. If nicotine, caffeine and cocaine will result to enough persistence in the air, their monitoring will become an important issue of global chemical watching in the next future.

    Gu, Yao; Ni, Yongnian; Kokot, Serge

    2012-09-13

    A novel, simple and direct fluorescence method for analysis of complex substances and their potential substitutes has been researched and developed. Measurements involved excitation and emission (EEM) fluorescence spectra of powdered, complex, medicinal herbs, Cortex Phellodendri Chinensis (CPC) and the similar Cortex Phellodendri Amurensis (CPA); these substances were compared and discriminated from each other and the potentially adulterated samples (Caulis mahoniae (CM) and David poplar bark (DPB)). Different chemometrics methods were applied for resolution of the complex spectra, and the excitation spectra were found to be the most informative; only the rank-ordering PROMETHEE method was able to classify the samples with single ingredients (CPA, CPC, CM) or those with binary mixtures (CPA/CPC, CPA/CM, CPC/CM). Interestingly, it was essential to use the geometrical analysis for interactive aid (GAIA) display for a full understanding of the classification results. However, these two methods, like the other chemometrics models, were unable to classify composite spectral matrices consisting of data from samples of single ingredients and binary mixtures; this suggested that the excitation spectra of the different samples were very similar. However, the method is useful for classification of single-ingredient samples and, separately, their binary mixtures; it may also be applied for similar classification work with other complex substances.

    Recruitment method can impact the sample composition of a clinical trial and, thus, the generalizability of the results, but the importance of recruitment method in substance use disorder trials has received little attention. The present paper sought to address this research gap by evaluating the association between recruitment method and sample characteristics and treatment outcomes in a substance use disorder trial. In a multi-site trial evaluating Seeking Safety (SS), relative to Women's Health Education (WHE), for women with co-occurring PTSD (either sub-threshold or full PTSD) and substance use disorders, one site assessed the method by which each participant was recruited. Data from this site (n=106), which recruited participants from newspaper advertising and clinic intakes, were analyzed. Participants recruited through advertising, relative to those from the clinic, had significantly higher levels of baseline drug use and higher rates of meeting DSM-IV-TR criteria for full PTSD. Results suggest that the effectiveness of SS in decreasing PTSD symptoms was greater for participants recruited through advertising relative to those recruited from the clinic. Conversely, the results revealed a significant treatment effect in the clinic-recruited participants, not seen in the advertising-recruited participants, with SS, relative to WHE, participants being more likely to report past week drug use during the follow-up phase. Recruitment method may impact sample composition and treatment effects. Replication of this finding would have important implications for substance use disorder efficacy trials which often utilize advertising to recruit participants.

    The new Kreek-McHugh-Schluger-Kellogg scale ('KMSK scale') is designed to quantify self-exposure to opiates, cocaine, alcohol, and/or tobacco. Each section of the KMSK scale assesses the frequency, amount, and duration of use of a particular substance during the individual's period of greatest consumption. The scale also assesses the mode of use, whether the substance use is current or past, and whether each substance is the substance of choice. The administration time is under 5 min. In an initial validation study of this scale, 100 human subjects were administered the KMSK scale concurrently with the Structured Clinical Interview for DSM-IV (SCID-I DSM-IV version). The sensitivity and specificity were very good for opiates, cocaine, and alcohol use. In addition, the correlations between KMSK scores and the number of SCID-I criteria items met were excellent for opiates and cocaine and good for alcohol use. Nicotine dependence was not assessed in this study as there is no SCID-I nicotine criteria. These preliminary results show that the KMSK scale may have both construct validity similar to that of other established self-report measures and the potential to be an effective screening instrument for the assessment of a lifetime diagnosis of alcohol, opiate, or cocaine dependence.

    1998-12-31

    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.

    Full Text Available Traditional healers are acceptable and highly accessible health practitioners throughout sub-Saharan Africa. Patients in South Africa often seek concurrent traditional and allopathic treatment leading to medical pluralism.We studied the cause of five traditional illnesses known locally as "Mavabyi ya nhloko" (sickness of the head, by conducting 27 in-depth interviews and 133 surveys with a randomly selected sample of traditional healers living and working in rural, northeastern South Africa. These interviews were carried out to identify treatment practices of mental, neurological, and substance abuse (MNS disorders. Participating healers were primarily female (77%, older in age (median: 58.0 years; interquartile range [IQR]: 50-67, had very little formal education (median: 3.7 years; IQR: 3.2-4.2, and had practiced traditional medicine for many years (median: 17 years; IQR: 9.5-30. Healers reported having the ability to successfully treat: seizure disorders (47%, patients who have lost touch with reality (47%, paralysis on one side of the body (59%, and substance abuse (21%. Female healers reported a lower odds of treating seizure disorders (Odds Ratio (OR:0.47, patients who had lost touch with reality (OR:0.26; p-value<0.05, paralysis of one side of the body (OR:0.36, and substance abuse (OR:0.36 versus males. Each additional year of education received was found to be associated with lower odds, ranging from 0.13-0.27, of treating these symptoms. Each additional patient seen by healers in the past week was associated with roughly 1.10 higher odds of treating seizure disorders, patients who have lost touch with reality, paralysis of one side of the body, and substance abuse. Healers charged a median of 500 South African Rand (~US$35 to treat substance abuse, 1000 Rand (~US$70 for seizure disorders or paralysis of one side of the body, and 1500 Rand (~US$105 for patients who have lost touch with reality.While not all healers elect to treat MNS

    Full Text Available Objective to identify characteristics of the nature content and functioning of prohibition in the legal reality of Russia. nbsp Methods the methodological basis of research is the dialectical approach to cognition of social phenomena allowing to analyze them in historical development and functioning in the context of the totality of objective and subjective factors as well as a postmodern paradigm giving the opportunity to explore the legal reality at different levels. Dialectical approach and postmodern paradigm determined the choice of specific research methods comparative hermeneutic discursive. Results the paper proposes a definition of prohibition as a state socio volitional constraining limiting means that under the threat of legal liability is intended to prevent the wrongful act of the subject physical or legal entity and ensure the maintenance of law and order. Prohibition is a necessary means of ensuring the discipline of public relations and the consolidation of legal values designed to assure the effectiveness of legal regulation. Scientific novelty for the first time the article shows that prohibition as a legal category is the ontological basis of legal reality and acts as a determining factor in the content and focus not only of lawmaking and law enforcement but legal behavior as well. Practical significance the main provisions and conclusions of the article can be used in research and teaching when considering questions about the nature content and functioning of prohibitions.

    Identification and quantification of new psychoactive substances (NPS), both in biological and non-biological samples, represent a hard challenge for forensic toxicologists. NPS are increasingly emerging on illegal drug market. Many cases of co-consumption of NPS and other substances have also been reported. Hence, the development of analytical methods aiming at the detection of a broad-spectrum of compounds (NPS and "traditional" drugs) could be helpful. In this paper, a fully validated screening method in blood for the simultaneous detection of 69 substances, including 64 NPS (28 synthetic cannabinoids, 19 synthetic cathinones, 5 phenethylamines, 3 indanes, 2 piperazines, 2 tryptamines, 2 phencyclidine, methoxetamine, ketamine and its metabolite) and 5 amphetamines (amphetamine, methamphetamine, MDMA, MDA, 3,4-methylenedioxy-N-ethylamphetamine - MDEA-) by a dynamic multiple reaction monitoring analysis through liquid chromatography - tandem mass spectrometry (LC-MS/MS) is described. This method is very fast, easy to perform and cheap as it only requires the deproteinization of 200μL of blood sample with acetonitrile. The chromatographic separation is achieved with a C18 column. The analysis is very sensitive, with limits of quantification ranging from 0.1 to 0.5ng/mL. The method is linear from 1 to 100ng/mL and the coefficient of determination (R(2)) was always above 0.9900. Precision and accuracy were acceptable at any quality control level and recovery efficiency range was 72-110%. Matrix effects did not negatively affect the analytical sensitivity. This method was successfully applied to three real cases, allowing identification and quantification of: mephedrone and methamphetamine (post-mortem); ketamine, MDMA and MDA (post-mortem); AB-FUBINACA (ante-mortem).

    2016-01-01

    The design of new erythropoiesis-stimulating agents for clinical use necessitates constant development of methods for detecting the abuse of these substances, which are prohibited under the World Anti-Doping Code and are included in the World Anti-Doping Agency (WADA) prohibited list. This review integrates and describes systematically the published data on the key methods currently used by WADA-accredited anti-doping laboratories around the world to detect the abuse of erythropoiesis-stimulating agents, including direct methods (various polyacrylamide gel electrophoresis techniques, enzyme-linked immunosorbent assay, membrane enzyme immunoassay and mass spectrometry) and indirect methods (athlete biological passport). Particular attention is given to promising approaches and investigations that can be used to control prohibited erythropoietins in the near future. The bibliography includes 122 references

  15. Help-Seeking Behaviors for Intimate Partner Violence Perpetration by Men Receiving Substance Use Treatment: A Mixed-Methods Secondary Analysis.

    Hashimoto, Nozomu; Radcliffe, Polly; Gilchrist, Gail

    2018-05-01

    Despite the high prevalence of intimate partner violence (IPV) perpetration by men receiving substance use treatment, little is known about their help-seeking behaviors for IPV. A secondary analysis of a mixed-methods study of men receiving substance use treatment who perpetrated IPV examined the prevalence, characteristics, and barriers associated with IPV perpetration disclosure and help-seeking. In total, 170 men were interviewed using a structured questionnaire, and a subsample of 20 were interviewed in-depth about their experiences. Logistic regression determined variables associated with disclosure and help-seeking. Thematic analysis of the in-depth interviews explored barriers to disclosure and help-seeking. Only half the participants had told anyone about their IPV perpetration and about one quarter reported having sought any sort of support. Whereas participants were more likely to disclose their IPV perpetration to informal resources (such as friends or family), they tended to seek help from formal resources (such as health professionals or the police). A greater proportion of physical IPV perpetrators, who had disclosed, had been arrested or had police involvement for IPV, suggesting that their disclosure may not have been voluntary. The following themes emerged from the qualitative data about the barriers to disclosure and help-seeking for IPV perpetration: fear that their children would be taken into care by social services, shame and embarrassment, and a minimization or normalization of their behavior. In addition, many participants highlighted that they had never been previously asked about IPV during treatment for substance use and stressed the need for greater expertise in or knowledge of this topic from specialist services. Substance use treatment services should enquire about men's relationships and IPV perpetration to facilitate disclosure and provide support. Further research is necessary to determine the context of disclosure and help

    2016-01-01

    The aim of improving anti-doping efforts is predicated on several different pillars, including, amongst others, optimized analytical methods. These commonly result from exploiting most recent developments in analytical instrumentation as well as research data on elite athletes' physiology in general, and pharmacology, metabolism, elimination, and downstream effects of prohibited substances and methods of doping, in particular. The need for frequent and adequate adaptations of sports drug testing procedures has been incessant, largely due to the uninterrupted emergence of new chemical entities but also due to the apparent use of established or even obsolete drugs for reasons other than therapeutic means, such as assumed beneficial effects on endurance, strength, and regeneration capacities. Continuing the series of annual banned-substance reviews, literature concerning human sports drug testing published between October 2014 and September 2015 is summarized and reviewed in reference to the content of the 2015 Prohibited List as issued by the World Anti-Doping Agency (WADA), with particular emphasis on analytical approaches and their contribution to enhanced doping controls.

    2016-01-01

    Full Text Available A novel simple, direct and selective gas chromatography–mass spectrometry (GC/MS procedure was developed for the determination of the antihistamine drug dimenhydrinate (DMH in presence of six of its related substances and potential impurities, namely, diphenylmethane, diphenylmethanol, benzophenone, orphenadrine, caffeine and 8-chlorocaffeine. The method involved resolution of the underivatized compounds using a trifluoropropylmethyl polysiloxane (Rtx-200 capillary column and the mass spectrometric detection was carried out in the electron-impact (EI mode. Excellent baseline separation of DMH and the cited related substances was achieved in less than 15 min. Quantification of the parent drug DMH was based on measuring its peak area. The reliability and analytical performance of the proposed method were validated with respect to linearity, range, precision, accuracy, specificity, robustness, detection and quantification limits. Calibration curve of DMH was linear over the range 50–500 μg/mL with determination coefficient (R2 = 0.9982. The proposed method was successfully applied for the assay of DMH in tablets dosage form with recoveries >96.80%.

  20. Detection of diffusible substances

    1976-12-01

    The different steps of a radioautographic technique for the detection of diffusible substances are described. Using this radioautographic method, the topographic distribution of estradiol-concentrating neurons was studied in the nervous system and pituitary of the ovariectomized mouse and guinea-pig. A relatively good morphological preservation of structures can be ascertained on sections from unfixed, unembedded tissues prepared at low temperatures and kept-under relatively low humidity. The translocation or extraction of diffusible substances is avoided by directly mounting of frozen sections on dried photographic emulsion. Since no solvent is used, this technique excludes the major sources of diffusion artifacts and permits to be in favourable conditions for the localization of diffusible substances.

  1. Policy on reintegration of women with histories of substance abuse: A mixed methods study of predictors of relapse and facilitators of recovery

    Directory of Open Access Journals (Sweden)

    VanDeMark Nancy R

    2007-09-01

    Full Text Available Abstract Background The predominant U.S. policy approach toward individuals with substance abuse problems has relied on stigma and punishment by withholding access to education, cash assistance, housing, social support, and normal social roles. In contrast to this approach, the theory of reintegrative shaming asserts that providing individuals with the opportunity to reconnect with society is more effective in reducing potential to relapse to crime and drug abuse. Strategies that promote such reconnection include expanding access to basic needs and supportive relationships along with increasing opportunities to fully participate in mainstream social roles. Methods The present cross-sectional study examined the predictors of relapse and the facilitators of recovery in a sample of 325 women with histories of substance abuse. Analysis of secondary data, collected as part of a national cross-site study, employed a mixed methods approach conducting (1 logistic regression to examine the predictors of relapse and (2 an inductive qualitative analysis of responses from open-ended items to explore the women's perceptions of barriers to and facilitators of recovery. Results Results suggest that lower levels of instrumental support, affective support, and participation in normal roles (such as parent, employee, student, and citizen are significant predictors of relapse to drug use and criminal behaviors. Qualitative findings support the quantitative results, revealing that participating women perceived the variables of support and role participation as critical in facilitating their recovery. They also noted the importance of individual characteristics such as optimism and strength and emphasized the significance of their relationship with their children in motivating them to avoid relapse. Findings suggest that punitive policies toward women with substance abuse histories may be ineffective. Conclusion The author concludes that current policies designed to

    International Nuclear Information System (INIS)

    Knochel, A.; Eggers, I.; Klatte, B.; Wilken, R. D.

    1985-01-01

    A process for enriching and separating heavy hydrogen isotopes having a heavy hydrogen cation (deuterium and/or tritium) from substance streams containing them, wherein the respectively present hydrogen isotopes are exchanged in chemical equilibria. A protic, acid solution containing deuterium and/or tritium is brought into contact with a value material from the group of open-chained polyethers or aminopolyethers, macro-monocyclic or macro-polycyclic polyethers, macro-monocyclic or macro-polycyclic amino polyethers, and mixtures of these values, in their free or proton salt form to form a reaction product of the heavy hydrogen cation with the value or value salt and bring about enrichment of deuterium and/or tritium in the reaction product. The reaction product containing the value or value salt is separated from the solution. The separated reaction product is treated to release the hydrogen isotope(s) to be enriched in the form of deuterium oxide (HDO) and/or tritium oxide (HTO) by regenerating the value or its salt, respectively. The regenerated value is returned for reuse

    A test procedure is presented which permits to obtain, by means of a single carbon-14-labelled compound as structural element in a series of essential substances, a survey of important fields of liver function. Special attention was paid to cholesterol. Methodical studies resulted in an optimization of the application under in vivo and in vitro conditions, and of the isolation of carbon-14-labelled cholesterol, ester cholesterol and glucose as well as of carbon-14-labelled phospholipids, triglycerides, bile acids, proteins and nucleic acids as groups. A comparison of the experimental techniques demonstrated the advantages of in vivo application. The method and its validity are illustrated by an example (DDT). Its use in studies on various active principles will be dealt with in future communications. (author)

    In this review, tasks and methods of food toxicology as well as the application of the different toxicity tests for the risk assessment of food ingredients are described. Particular reference is made to short-term genotoxicity tests. Enzymatic digestion and extraction methods for complex foodstuffs which are used in the toxicological testing of foods in in vitro systems are described. Radiolytic products which result from irradiation of foods or components of foodstuffs and corresponding results of toxicity testing are reviewed. Foodstuffs irradiated with doses of up to 10 kGy are regarded as toxicologically safe. A survey of the toxicologically tested irradiated foodstuffs as well as the applied maximum doses are given in tables at the end of chapter 8. Among the great number of toxicological studies of irradiated foods those are especially mentioned which have given rise to discussions on the health risks involved. In addition, the difficulties associated with the testing of toxicity of irradiated foodstuffs in feeding experiments are discussed. Short-term tests used to establish the benotoxicity of irradiated foods and essential results of toxicological testing are also presented in tables. An overview is given of the occurrence, frequency and health risks of natural toxins in foods and harmful substances produced by conventional methods of cooking and preservation, in order to enable a comparison with the health risks of irradiated foods. The relevance of animal experiments and in vitro investigations for the prediction of toxic effects of harmful substances of foodstuffs in man is discussed in the final chapter. (VHE) [de

    Ritterbusch, Amy E

    2016-01-01

    This paper presents the participatory visual research design and findings from a qualitative assessment of the social impact of bazuco and inhalant/glue consumption among street youth in Bogotá, Colombia. The paper presents the visual methodologies our participatory action research (PAR) team employed in order to identify and overcome the stigmas and discrimination that street youth experience in society and within state-sponsored drug rehabilitation programmes. I call for critical reflection regarding the broad application of the terms 'participation' and 'participatory' in visual research and urge scholars and public health practitioners to consider the transformative potential of PAR for both the research and practice of global public health in general and rehabilitation programmes for street-based substance abuse in Colombia in particular. The paper concludes with recommendations as to how participatory visual methods can be used to promote social inclusion practices and to work against stigma and discrimination in health-related research and within health institutions.

    2015-06-01

    Full Text Available A new simple, rapid, accurate and precise High – Performance Liquid Chromatography (HPLC method for determination of benzylpenicillin potassium and streptomycin sulphate in Ascomicin ointment was developed and validated. The method can be used for the detection and quantification of known and unknown impurities and degradation products in this pharmaceutical product during routine analysis and also for stability studies in view of its capability to separate degradation products. The method was validated for accuracy, precision, specificity, robustness and quantification limits according to ICH Guidelines. The estimation of benzylpenicillin potassium and streptomycin sulphate was done by Waters HPLC 2695. The chromatographic conditions comprised a reverse-phased C18 column (5 µm particle size, 250 mm×4.6 mm i.d. with a mobile phase consisting of a mixture of solution in water containing 0.025 M of sodium phosphate dibasic and 0.02 of sodium hexansulfonate adjusted to pH 6.0 with 22.5 g/lsolution of phosphoric acid and acetonitrile in gradient elution. The flow rate was 0.8 ml/min. Standard curves were linear over the concentration range of 5.00 µg/ml to 5.00 mg/ml for streptomycin sulphate and 3.26 µg/ml to 3.26 mg/ml for benzylpenicillin potassium. Statistical analyses proved the method was precise, reproducible, selective, specific and accurate for analysis of benzylpenicillin potassium, streptomycin sulphate and related substances.

  2. Assessment of dietary intake of flavouring substances within the procedure for their safety evaluation: advantages and limitations of estimates obtained by means of a per capita method.

    Science.gov (United States)

    Arcella, D; Leclercq, C

    2005-01-01

    The procedure for the safety evaluation of flavourings adopted by the European Commission in order to establish a positive list of these substances is a stepwise approach which was developed by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and amended by the Scientific Committee on Food. Within this procedure, a per capita amount based on industrial poundage data of flavourings, is calculated to estimate the dietary intake by means of the maximised survey-derived daily intake (MSDI) method. This paper reviews the MSDI method in order to check if it can provide conservative intake estimates as needed at the first steps of a stepwise procedure. Scientific papers and opinions dealing with the MSDI method were reviewed. Concentration levels reported by the industry were compared with estimates obtained with the MSDI method. It appeared that, in some cases, these estimates could be orders of magnitude (up to 5) lower than those calculated considering concentration levels provided by the industry and regular consumption of flavoured foods and beverages. A critical review of two studies which had been used to support the statement that MSDI is a conservative method for assessing exposure to flavourings among high consumers was performed. Special attention was given to the factors that affect exposure at high percentiles, such as brand loyalty and portion sizes. It is concluded that these studies may not be suitable to validate the MSDI method used to assess intakes of flavours by European consumers due to shortcomings in the assumptions made and in the data used. Exposure assessment is an essential component of risk assessment. The present paper suggests that the MSDI method is not sufficiently conservative. There is therefore a clear need for either using an alternative method to estimate exposure to flavourings in the procedure or for limiting intakes to the levels at which the safety was assessed.

    The purpose of this study was to evaluate the effect of the various light curing units (plasma arc, halogen and light-emitting diodes) and irradiation methods (one-step, two-step and pulse) using different light energy densities on the leachability of unreacted monomers (Bis-GMA and UDMA) and the surface hardness of a composite resin (Z250, 3M). Leachability of the specimens immersed for 7 days in ethanol was analysed by HPLC. Vicker's hardness number (VHN) was measured immediately after curing (IC) and after immersion in ethanol for 7 days. Various irradiation methods with three curing units resulted in differences in the amount of leached monomers and VHN of IC when light energy density was lower than 17.0 J cm(-2) (P = 0.05). However, regardless of curing units and irradiation methods, these results were not different when the time or light energy density increased. When similar light energy density was irradiated (15.6-17.7 J cm(-2)), the efficiency of irradiation methods was different by the following order: one-step > or = two-step > pulse. These results suggest that the amount of leached monomers and VHN were influenced by forming polymer structure in activation and initiation stages of polymerization process with different light source energies and curing times.

    Full Text Available Aim of the Study: To assess the prevalence and pattern of substance use among male adolescents in Sunder Nagari, New Delhi. Materials and Methods: A cross-sectional survey was designed to assess the prevalence and pattern of substance use among male adolescents in New Delhi. One hundred and ten adolescents were conveniently selected from Sunder Nagari, New Delhi. Adolescents aged more than 11 years and able to read and write Hindi or English were included in the study. A structured questionnaire for demographic variables was developed by researchers. To assess the prevalence and pattern of substance use, a structured questionnaire was prepared with the reliability coefficient of 0.94 (test-retest reliability with a content validity index of 0.90 between the experts. Data were collected from the subjects after getting their written consent. Data analyzed using statistical package SPSS version 17.0. The level of significance was set as P < 0.05. Results: The study findings revealed that nearly more than half (55.6% of the male adolescents reported the use of one or more substances in their lifetime. About 44.26% of the adolescents started to use substances before 13 years of age. Most common reason specified by the subjects to take substance were to be liked by friends (57.38%, to feel like an adult (24.6%, and few of them reported: “like the feeling of substances” (13.11% as reason for taking substances. Common substances used by the subjects were any kind of tobacco (77.05%, inhalants (26.23%, and alcohol (11.47%. Most of the subjects were getting substances from their friends (85.25% and only a few (14.75% by themselves.

    Sewage-based epidemiology (SBE) employs the analysis of sewage to detect and quantify drug use within a community. While SBE has been applied repeatedly for the estimation of classical illicit drugs, only few studies investigated new psychoactive substances (NPS). These compounds mimic effects of illicit drugs by introducing slight modifications to chemical structures of controlled illicit drugs. We describe the optimization, validation, and application of an analytical method using liquid chromatography coupled to positive electrospray tandem mass spectrometry (LC-ESI-MS/MS) for the determination of seven NPS in sewage: methoxetamine (MXE), butylone, ethylone, methylone, methiopropamine (MPA), 4-methoxymethamphetamine (PMMA), and 4-methoxyamphetamine (PMA). Sample preparation was performed using solid-phase extraction (SPE) with Oasis MCX cartridges. The LC separation was done with a HILIC (150 x 3 mm, 5 µm) column which ensured good resolution of the analytes with a total run time of 19 min. The lower limit of quantification (LLOQ) was between 0.5 and 5 ng/L for all compounds. The method was validated by evaluating the following parameters: sensitivity, selectivity, linearity, accuracy, precision, recoveries and matrix effects. The method was applied on sewage samples collected from sewage treatment plants in Belgium and Switzerland in which all investigated compounds were detected, except MPA and PMA. Furthermore, a consistent presence of MXE has been observed in most of the sewage samples at levels higher than LLOQ. Copyright © 2015 John Wiley & Sons, Ltd.

    The paper presents the results of the study into the laws that govern the process of treating by oxidation the stillage residues of liquid radioactive wastes to remove organic compounds and transuranium elements with the use of hydrogen peroxide, potassium permanganate and subsequent ultra-filtration. The optimum oxidisation regime has been defined on the basis of this study to ensure that the initial dichromate oxidability of LRW's stillage residues decreases from 6,000-9,500 to 500-1,000 mg O/I, whereas the TUE activity associated with the key isotopes is reduced by 74-87 % for 238,239,240 Pu, by 94-95 % for 241 Am, and by 90-95 % for 244 Cm. The concentration of uranium decreases by 94-99 %. It is proposed to implement this method at the Chernobyl NPP site.

    Full Text Available The winter squash is an important source of antioxidants, especially carotenoids. The aim of submitted research work was to determine the effect of genotype, storage and different methods of technological processing (baking, boiling and sterilization on the content of ascorbic acid and total carotenoids in fruits of winter squash (Cucurbita moschata Duch. ex Poir.. The small-plot field experiment was established at Slovak University of Agriculture in Nitra in 2013. Five cultivars of winter squash (‘Liscia’, ‘Orange’, ‘Hannah’, ‘UG 205 F1’ and ‘Waltham’ were examined in experiment. The total carotenoids content in the pulp of fresh fruits was ranged from 9.33 to 15.10 mg.100 g−1. Its highest value was determined in case of ‘Orange’ variety. The storage and the thermal treatment of fruit pulp in case of baking had positive impact from the total carotenoid content point of view. The baking resulted in the increase of its value in winter squash. On the contrary, sterilization tended to the decrease of total carotenoid content in edible part of squash. The total carotenoids content in the baking pulp was ranged from 14.27 to 31.87 mg.100 g−1. The vitamin C content before storage and technological processing ranged in interval from 13.88 to 18.69 mg.100 g−1. Particular thermal methods of processing and storage resulted in decrease of vitamin C content in the pulp of all winter squash varieties.

    A hybrid model based on the positive matrix factorization (PMF) model and the health risk assessment model for assessing risks associated with sources of perfluoroalkyl substances (PFASs) in water was established and applied at Dianchi Lake to test its applicability. The new method contains 2 stages: 1) the sources of PFASs were apportioned by the PMF model and 2) the contribution of health risks from each source was calculated by the new hybrid model. Two factors were extracted by PMF, with factor 1 identified as aqueous fire-fighting foams source and factor 2 as fluoropolymer manufacturing and processing and perfluorooctanoic acid production source. The health risk of PFASs in the water assessed by the health risk assessment model was 9.54 × 10 -7  a -1 on average, showing no obvious adverse effects to human health. The 2 sources' risks estimated by the new hybrid model ranged from 2.95 × 10 -10 to 6.60 × 10 -6  a -1 and from 1.64 × 10 -7 to 1.62 × 10 -6  a -1 , respectively. The new hybrid model can provide useful information on the health risks of PFAS sources, which is helpful for pollution control and environmental management.

    Suicides among men aged 35-64 years increased by 27% between 1999 and 2013, yet little research exists to examine the nature of the suicide risk within this population. Many men do not seek help if they have mental health problems and suicides may occur in reaction to stressful circumstances. We examined the precipitating circumstances of 600 suicides without known mental health or substance abuse (MH/SA) problems and with a recent crisis. Whether these suicides occurred within the context of an acute crisis only or in the context of chronic circumstances was observed. Using data from the National Violent Death Reporting System and employing mixed-methods analysis, we examined the circumstances and context of a census of middle-aged male suicides (n = 600) in seven states between 2005 and 2010. Precipitating circumstances among this group involved intimate partner problems (IPP; 58.3%), criminal/legal problems (50.7%), job/financial problems (22.5%), and health problems (13.5%). Men with IPP and criminal/legal issues were more likely than men with health and/or job/financial issues to experience suicide in the context of an acute crisis only. Suicides occurring in reaction to an acute crisis only or in the context of acute and chronic circumstances lend themselves to opportunities for intervention. Further implications are discussed.

    Concerning the measurement system of ultra-micro hazardous chemical substances in the global environment, the paper examined the present situation of chemical substances such as dioxins, made an experimental study on the method to analyze dioxins in exhaust gas from an aspect of international consistency, and worked out a JIS draft. As to the standard measuring method of hormone effects of chemical substances, the paper developed the competitive bonding experiment system to measure bonding ability of chemical substances to homo sapiens estrogen receptor (ER). By measuring ER bonding ability of 78 kinds of chemical substances, the measuring method was developed. In the development of the assay system for detection of hormone-like compounds, the assay system with transfer activity via estrogen receptor as an index was established using cultured cells and yeast. Further, the development was made of a measuring method of receptor bonding activity of hormone-like substances. 33 refs., 151 figs., 66 tabs.

    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

    Teenage substance use is a global challenge, and youths residing in Kuwait are not immune from it. Tobacco products are licit; however, alcohol and other mood-altering illicit substance are prohibited with severe penalties including imprisonment. Youths residing in Kuwait are being initiated into the use of mood-altering substances like tobacco at an early age, and it is postulated that, as they grow older, they may progress into using alcohol and other prohibited illicit drugs. The aim of this study was to determine licit and illicit substance use by teenagers residing in Kuwait. The study will also explore their awareness of substance use among their peers. A cross-sectional survey using a snowball sampling technique was used to recruit 190 teenagers aged 15-18 years residing in Kuwait. Data were collected using the 130-item questionnaire adapted from 1998 New Jersey Triennial Public High School Survey of Drug and Alcohol Use. Data collection was from September 2012 to June 2013. The Statistical Package for Social Sciences Version 22 for Windows was used. Pearson's chi-square, Kruskal-Wallis, and Mann-Whitney U tests were used to test the hypotheses. Tobacco was the most commonly used substance by these teenagers; 8.4% were current smokers, and 50% had experimented. Age of initiation for 21% was before 14 years old. Hashish (marijuana) was the most commonly used illicit drug, with 3.7% current users and 5.3% claiming to have used it. More male than female teenagers in Grade 9 were using tobacco products (χ = 27.428, df = 5, p abuse of mood/mind-altering licit and illicit substances appear to be increasing among older teenagers. Intensifying campaigns about the hazards of substance use and drug testing should start from the primary school level.

Among equipment of the medical staff escorting the patient, there are several devices and materials which are considered hazardous for security reasons. However, medical equipment and substances are indispensable for treating patients during the flight. The aim of the author was to present his experience obtained with the use of an instrument developed for testing liquids, aerosols and gels for security reasons. An instrument based on Raman spectroscopy was used for the identification of medical substances. The results confirmed that the instrument was able to recognize the tested medical substances. The non-destructive testing maintained sample integrity and asepsis. The data indicate that the instrument has a promising utility for the identification of medical substances. It seems important that during repatriation medical substances should be selected not only on the ground of their medical necessity, but their packaging should be also taken into consideration. It is necessary to perform more tests on different medical substances used in emergency care in order to make the database of medical substances stored in the library of instrument more complete.

    Nuclear physical methods of analysis using the absorption effect of ionising radiation should satisfy the following requirements for industrial practice. First, the ionising radiation should have a high penetrating ability in the environment examined to ensure a representative nature of the data and reliability of the analysis. Secondly, the absorption degree of radiation should be sufficient to maintain the sensitivity and accuracy of the measurements. In addition, to keep the necessary selectivity, the neutron absorption analysis on thermal neutrons is applied on chemical elements and their isotopes with an anomalously high absorption cross section about 10 2 - 10 4 barn. To such elements belong Gd, Sm, B, Cd, Hg and others. Based on the exponential law of absorption for thermal neutrons, an analytical expression was obtained for the concentration of the element analyzed in dependence on the flow of the elapsed neutrons. A number of interfering factors such as the matrix effect of the filling agent, scattering of neutrons, dispersion of the density and of the temperature of the environment, and background radiation have to be taken into account. Owing to the difference between the experimental calibration dependence and the exponential one, the methods of its mathematical approximation, for example, polynomial function and partially hyperbolic one are considered. The scheme realisation of the method is feasible in geometry 'on passage' and 'on reflection' of the neutron flow. Radionuclide Pu-Be sources are preferred as the neutron sources based on nuclear reactions of the (α,n) type. Detectors used for registration of slow neutrons are gas discharge corona 3 He-filled counters. Hydrogen-containing substances with good scattering properties are utilised as the fast neutron moderators. The neutron absorption method has found wide application in the nuclear power engineering and atomic industry. This method is intended for continuous automatic monitoring of

  5. Study of a method for reducing fuel consumption and the amount of specific emissions of harmful substances with exhaust gases of passenger cars when using the “climate control” system

    The article deals with the issue of improving the fuel economy and environmental friendliness of motor vehicles which serve the administrative and management personnel of the oil and gas industry. It is established that fuel consumption and the amount of specific emissions of harmful substances with exhaust gases of cars when using the “climate control” system depend on the effective ambient temperature, the color of the opaque car body elements, the power of the car engine and the interior volume. However, the simplest controlled factor is the color of the opaque car body elements, which is characterized by the coefficient of light reflection. In the course of experimental studies, we established the dependences of a change in fuel consumption and a share of reducing emissions of harmful substances with exhaust gases of passenger cars with the “climate control” system on the coefficient of light reflection. A method has been developed to reduce fuel consumption and the amount of specific emissions of harmful substances with the exhaust gases of passenger cars using the “climate control” system, which involves painting the vehicle roof white and allows reducing fuel consumption by 5.5-10.3%, and the amount of specific emissions of harmful substances by 0.8-2.3%.

    Stiefel, C; Schwack, W

    2013-12-01

    Most UV filters used in sunscreens and other cosmetic products contain carbonyl groups, which generally are able to react with peptides or free amino acids of the human skin. To estimate their reactivity, we studied different prominent UV filter substances, octocrylene, ethylhexyl salicylate, 4-t-butyl-4'-methoxydibenzoylmethane, ethylhexyl methoxycinnamate, benzophenone-3, hydroxymethylbenzoyl sulphonic acid, octyldimethyl p-aminobenzoic acid, 3-benzylidene camphor, 4-methylbenzylidene camphor, diethylhexyl butamido triazone and ethylhexyl triazone. A simple screening method using an amino HPTLC plate as protein model was established. The influence of different reaction conditions like heating and irradiation was determined. The ketones BP-3, HMBS and BM-DBM revealed the highest binding rates after both irradiation and heating. After 1 h of irradiation, 82%, 28% and 96%, respectively, were bonded to the amino phase, while heating resulted in values of 52%, 36% and 16%. For BP-3 and HMBS, even storage in the dark at room temperature resulted in a low binding. Contrarily, for the two camphor derivatives 3-BC and 4-MBC, only irradiation led to a slightly turnover. UV filters with ester groups also showed a different behaviour depending on their main skeleton. While OCR especially reacted under heating with the amino phase, resulting in 36% of bound species after one hour, UV irradiation particularly encouraged a reaction of the other esters. After 1 h irradiation, 15% of EHMC, 38% of EHS and 48% of OD-PABA were bonded to the amino groups of the HPTLC plate, whereas the reactivity of the two triazones, EHT and DEBT, was comparatively low. Especially the UV filters BP-3, BM-DBM, HMBS, EHMC or OCR, which are commonly known to cause contact dermatitis, showed a high tendency to form adducts with the amino layer. Thus, the amino plate seems to be a proper tool to screen for skin sensitizers. © 2013 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

  8. Human embryo cloning prohibited in Hong Kong.

    Science.gov (United States)

    Liu, Athena

    2005-12-01

    Since the birth of Dolly (the cloned sheep) in 1997, debates have arisen on the ethical and legal questions of cloning-for-biomedical-research (more commonly termed "therapeutic cloning") and of reproductive cloning using human gametes. Hong Kong enacted the Human Reproductive Technology Ordinance (Cap 561) in 2000. Section 15(1)(e) of this Ordinance prohibits the "replacing of the nucleus of a cell of an embryo with a nucleus taken from any other cell," i.e., nucleus substitution. Section 15(1)(f) prohibits the cloning of any embryo. The scope of the latter, therefore, is arguably the widest, prohibiting all cloning techniques such as cell nucleus replacement, embryo splitting, parthenogenesis, and cloning using stem cell lines. Although the Human Reproductive Technology Ordinance is not yet fully operative, this article examines how these prohibitions may adversely impact on basic research and the vision of the Hong Kong scientific community. It concludes that in light of recent scientific developments, it is time to review if the law offers a coherent set of policies in this area.

    The health-related evaluation of pollutants is a necessary basis for regulations in many sectors of environmental protection. It has been a concern of the Federal Ministry for the Environment, Nature and Nuclear Safty (Dessau-Rosslau, Federal Republic of Germany) to documentate and to describe the methods and procedures for health assessment of substances in environmental media. The compilation provides a comparison of methods with each other and especially with the derivation method of 'derived no-effect levels' according to the EU legislation on chemicals. In addition to the substantial compliance of the derivation methodology, the comparison shows differences in some aspects of the derivation methodology.

    Dugdale, Stephanie; Elison, Sarah; Davies, Glyn; Ward, Jonathan

    2017-06-01

    There is insufficient research examining the implementation of complex novel interventions within health care. This may be due to a lack of qualitative research providing subjective insights into these implementation processes. The authors investigate the advantages of applying behavior change theories to conceptualize qualitative data describing the processes of implementation of complex interventions. Breaking Free Online (BFO), a digital treatment intervention for substance misuse, is described as an example of a complex intervention. The authors review previous qualitative research which explored initial diffusion, or spread, of the BFO program, and its subsequent normalization as part of standard treatment for substance misuse within the health and social care charity, "Change, Grow, Live" (CGL). The use of behavior change models to structure qualitative interview findings enabled identification of facilitators and barriers to the use of BFO within CGL. These findings have implications for the development of implementation research in novel health care interventions.

  7. Radioiodination of humic substances

    Energy Technology Data Exchange (ETDEWEB)

    Franke, K.; Kupsch, H. [Inst. of Interdisciplinary Isotope Research, Leipzig (Germany)

    2010-07-01

    The known IODO-GEN trademark -method was adapted for radiolabeling of humic and fulvic acids with {sup 131}I. The water insoluble oxidizing agent 1,3,4,6tetrachloro-3{alpha},6{alpha}-diphenylglycoluril (IODO-GEN trademark) forms an iodous ion species (I{sup +}), which undergoes an electrophilic I/H-substitution on aromatic moieties of the humic and fulvic acids. This method offers mild conditions with a lesser extent of oxidative alterations of the target molecule, accompanied by an easy handling due to the virtual water-insolubility of the oxidizing agent. The method was optimized and different techniques were tested for the purification of the radioiodinated humic material. The yield of the labeling procedure varies between 45 and 75% depending on the provenance of the humic material and the applied purification method. A specific activity up to 40 MBq/mg was achieved. Furthermore, the known inherent photo-susceptibility of the iodinated humic substance and the influence of reducing agents were verified. An additional release of {sup 131}I up to 20% and up to 35%, respectively were observed. (orig.)

  10. Using response-time latencies to measure athletes’ doping attitudes: the brief implicit attitude test identifies substance abuse in bodybuilders

    Science.gov (United States)

    2014-01-01

    Background Knowing and, if necessary, altering competitive athletes’ real attitudes towards the use of banned performance-enhancing substances is an important goal of worldwide doping prevention efforts. However athletes will not always be willing to reporting their real opinions. Reaction time-based attitude tests help conceal the ultimate goal of measurement from the participant and impede strategic answering. This study investigated how well a reaction time-based attitude test discriminated between athletes who were doping and those who were not. We investigated whether athletes whose urine samples were positive for at least one banned substance (dopers) evaluated doping more favorably than clean athletes (non-dopers). Methods We approached a group of 61 male competitive bodybuilders and collected urine samples for biochemical testing. The pictorial doping Brief Implicit Association Test (BIAT) was used for attitude measurement. This test quantifies the difference in response latencies (in milliseconds) to stimuli representing related concepts (i.e. doping–dislike/like–[health food]). Results Prohibited substances were found in 43% of all tested urine samples. Dopers had more lenient attitudes to doping than non-dopers (Hedges’s g = -0.76). D-scores greater than -0.57 (CI95 = -0.72 to -0.46) might be indicative of a rather lenient attitude to doping. In urine samples evidence of administration of combinations of substances, complementary administration of substances to treat side effects and use of stimulants to promote loss of body fat was common. Conclusion This study demonstrates that athletes’ attitudes to doping can be assessed indirectly with a reaction time-based test, and that their attitudes are related to their behavior. Although bodybuilders may be more willing to reveal their attitude to doping than other athletes, these results still provide evidence that the pictorial doping BIAT may be useful in athletes from other sports

    The objective of this study is to investigate the relationship between excitatory substances by testing the urine in children with Tourette syndrome (TS). We performed a control study involving 44 patients with TS and 44 normal children by investigating the children's daily eating habits. We used the gas chromatograph-mass spectrometer and liquid chromatograph-mass spectrometer from Agilent. Substances for detection included 197 excitatory substances prohibited by the International Olympic Committee and other substances with similar chemical structures or biological functions for urine samples. Forty-four patients who did not take any drugs in the past 2 weeks enrolled in the study. The positive rate in the experiment group was three cases, while it was negative in the control group. The level of 1-testosterone increased in one extremely severe TS patient who ate large amounts of puffed food and drank an average of 350 ml of cola per day. Cathine and other substances with similar chemical constitution or similar biological effects increased in one severe TS patient who ate bags of instant noodles daily, according to the high score of the Yale Global Tic Severity Scale. An increase in ephedrine type, testosterone, and stimulants may be related to the pathogenesis of TS. Unhealthy food possibly causes TS. The relationship between excitatory substances and TS needs to be explored with the goal of providing more information on diagnosing and treating TS.

    2010-01-01

    Full text: Government of the Republic of Tajikistan has signed Convention "On prohibition of chemical weapon application"and no chemical weapon (CHW) is produced on the territory of republic. However, the potential production of CHW by individual persons or groups can be organized, using available production and obtaining chemical substances from other countries. Chemical substances, which have strong damage effect, easily, can be synthesized in chemical laboratories. These are general toxic substances, as hydrocyanic acid acid, phosgene, mustard gas, lewisite, sarin and others. The similar chemical substances of industrial significance are produced in Tajikistan: ammonia, chlorine, explosives, caustic soda, carbamide, formaldehyde and others. For industrial needs and agriculture from other countries Tajikistan is receiving the following: sodium cyanide and potassium for gold-mining; mineral acids; pesticides and others. Besides, there are different deposits in Tajikistan, reprocessing of which gives an opportunity to obtain different chemical substances. What can be obtained from chemicals produced in Tajikistan? Chlorine - from this reagent the fluoride chlorine, phosgene COCl_2 and many other compounds are easily synthesized, which are CHW components. Obtained cyanic compounds for gold mining can be used as precursor for neuroparalytic action. A big amount of metallic aluminum is produced in the republic. The Al powder for rocket fuel can be obtained from it. Obtained from other countries pesticides are potential components for CHW creation. A strong control and account of pesticides use is necessary. It is extremely important to control materials, equipment and technologies which allow countries and separate groups to create weapons of mass destruction (WMD). The most important factor is goods identification. Firstly - inspection of external view, labeling, packing specifications, license availability and etc. Strong control of checklists is necessary according

  14. Today's fentanyl crisis: Prohibition's Iron Law, revisited.

    Science.gov (United States)

    Beletsky, Leo; Davis, Corey S

    2017-08-01

    More than a decade in the making, America's opioid crisis has morphed from being driven by prescription drugs to one fuelled by heroin and, increasingly, fentanyl. Drawing on historical lessons of the era of National Alcohol Prohibition highlights the unintended, but predictable impact of supply-side interventions on the dynamics of illicit drug markets. Under the Iron Law of Prohibition, efforts to interrupt and suppress the illicit drug supply produce economic and logistical pressures favouring ever-more compact substitutes. This iatrogenic progression towards increasingly potent illicit drugs can be curtailed only through evidence-based harm reduction and demand reduction policies that acknowledge the structural determinants of health.

    Kraanen, Fleur L; Emmelkamp, Paul M G

    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.

    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.

    According to the Act on Counteracting Drug Addiction (20-th of March, 2009, Dz. U. Nr 63 poz. 520.) the list of federally prohibited plants in Poland was expanded to include 16 new species. Until that time the only illegal plant materials were cannabis, papaver, coca and most of their products. The actual list of herbal narcotics includes species which significantly influence on the central nervous system work but which are rarely described in the national literature. The plants usually come from distant places, where--among primeval cultures--are used for ritual purposes. In our civilization the plants are usually used experimentally, recreationally or to gain particular narcotic effects. The results of the consumption vary: they can be specific or less typical, imitate other substances intake, mental disorders or different pathological states. The plant active substances can interact with other medicaments, be toxic to internal organs, cause serious threat to health or even death. This article describes the sixteen plant species, which are now prohibited in Poland, their biochemical ingredients and their influence on the human organism.

    A well functioning immune system is essential in maintaining integrity of the organism, and malfunction may have severe health consequences. Environmental substances may pose direct toxicity to components of the immune system, often leading to immunosuppression and resulting reduced resistance to infections and tumors. Alternatively, such substances may be recognized by the immune system in a specific fashion, which may result in allergy and autoimmunity. A proper risk assessment of environmental substances in terms of immunotoxicity is necessary. In this manuscript, I reviewed recent three topics about immunotoxicity: (1) IPCS/WHO Guidance for immunotoxicity risk assessment for chemicals, (2) Intestinal immunotoxicity, and (3) Epicutaneous sensitization of food proteins.

    New and improved methods are described for the distillation of bituminous schistus and other bituminous substances, as well as for the purification, rectification, and preparation necessary for the employment of the productions obtained by such distillation for various useful purposes. This invention consists, first, in the arrangement and construction of furnace or apparatus for the distillation of schistus, and (any) other bituminous rocks. This furnace is made of circular brick-work, and is provided with the requisite number of fires placed round the circumference. The retort is of a conical or funnel shape, and when ready for use, has the appearance of one inverted cone being placed within a larger cone, in such a manner as to leave a space between the two cones for the reception of the schistus. Both cones are capable of being closed at their apexes, and their mouths, which are placed upwards, are connected together, and hermetically closed by a flat ring. The flame draft is caused to impinge against the lower portion of the outer cone and ascending, turns over the upper edge and descends within the inner cone to the mouth of the chimney, which is placed in the interior, and as low as may be convenient. A third cone is so placed within the inner cone as to cause the flame draft, in its descent, to bind against the surface of the retort.

    Full Text Available substance abuse' specially opiates and prescribed drugs are spreading among the older adults. Most of the time it begins as an attempt to medicate chronic pains, medical conditions and loneliness. In other instances, it simply is the continuation of a problem that begun in young adulthood. But scholars and specialists in both fields of Addiction and Gerontology, rather neglected this fast growing problem, to the extent that we almost have no data on the epidemiology, prevention and treatment modalities among the substance abusing old adults in Iran. This paper reflects the necessity of designing age specific programs to identify and treat this group. Besides, some of the most effictive methods of treatment in other countries are reviewed.

    2013-05-15

    The use of doping agents, once restricted to professional athletes, has nowadays become a problem of public health, since it also concerns young people and non-competing amateurs in different sports. The use is also diffused in social life for improving physical appearance and enhancing performance and even dietary supplements assumed to improve performance often contain anabolic steroids. While decades ago the so-called "classical doping agents" (like stimulants and narcotics) were used, to-day anabolic steroids are more widely diffused. Anabolic steroids are synthetic substances prepared by introducing modifications in the molecular structure of testosterone, the main natural androgenic anabolic steroid that forms in testes interstitial cells. The first report concerning the use of anabolic steroids by an athlete who searched for increased weight and power dates 1954. In 1974 the misuse of anabolic steroids in sports was banned by the International Olympic Committee and control tests were implemented in 1976 Montreal Olympic Games through radioimmunoassay analysis: the technique, however, only allows for unspecific detection of a limited number of exogenous steroids. Over the years, always new doping substances are synthesized and, as a consequence, the list of prohibited compounds is continuously updated and new suitable analytical methods for their detection and determination in biological matrices are continuously required. In doping control analysis the knowledge of steroid metabolism pathway in human body is of primary importance and the analytical methods must permit the simultaneous detection and determination not only of the forbidden precursor agents but also of their metabolites. In addition, the potential presence and amount in the biological samples of species that can interfere in the analysis should be evaluated. Also the several anabolic steroids, specifically designed to circumvent doping control, put on the market have been incorporated in the

    To screen the harmful substance 5-hydroxymethyl furfural content in commercially available traditional Chinese medicine injection which are commonly used, and to preliminarily evaluate the quality of these injections, 5-hydroxymethyl furfural was taken as an index. The contents of 5-hydroxymethyl furfural in 56 samples which consist of 23 kinds of traditional Chinese medicine injections and glucose injection were determined using LC-MS/MS, and 5-hydroxymethyl furfural was detected in 52 of these samples. The minimal content was 0.0038 microg x L(-1) and the maximum content was 1420 microg x mL(-1). The contents of 5-hydroxymethyl furfural were significantly different in traditional Chinese medicine injection which came from different kinds, manufacturers or batches. The results showed the quality difference of commercially available traditional Chinese medicine injection is significant taking 5-hydroxymethyl furfural content as assessment index. More attention should be paid to the safety of 5-hydroxymethyl furfural in traditional Chinese medicine injection, and unified limitation standard should be set to improve medication safety of traditional Chinese medicine injection.

  12. Ozone depleting substances management inventory system

    Directory of Open Access Journals (Sweden)

    Felix Ivan Romero Rodríguez

    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.

    2014-05-01

    The present study was designed to provide preliminary information on the potential impact of metabolic drug-drug interaction on the effectiveness of doping control strategies currently followed by the anti-doping laboratories to detect the intake of banned agents. In vitro assays based on the use of human liver microsomes and recombinant CYP isoforms were designed and performed to characterize the phase I metabolic profile of the prohibited agent toremifene, selected as a prototype drug of the class of selective oestrogen receptor modulators, both in the absence and in the presence of medicaments (fluconazole, ketoconazole, itraconazole, miconazole, cimetidine, ranitidine, fluoxetine, paroxetine, nefazodone) not included in the World Anti-Doping Agency list of prohibited substances and methods and frequently administered to athletes. The results show that the in vitro model developed in this study was adequate to simulate the in vivo metabolism of toremifene, confirming the results obtained in previous studies. Furthermore, our data also show that ketoconazole, itraconazole, miconazole and nefazodone cause a marked modification in the production of the metabolic products (i.e. hydroxylated and carboxylated metabolites) normally selected by the anti-doping laboratories as target analytes to detect toremifene intake; moderate variations were registered in the presence of fluconazole, paroxetine and fluoxetine; while no significant modifications were measured in the presence of ranitidine and cimetidine. This evidence imposes that the potential effect of drug-drug interactions is duly taken into account in anti-doping analysis, also for a broader significance of the analytical results.

    Organic residuals in sewage, which are not removed completely by waste water treatment may be relevant in environmental toxicology and may disturb drinking water treatment processes. The organic residuals must be identified before new techniques to eliminate these substances from waste water can be developed and steps can be taken to prevent them from polluting waste waters. In the research project sum parameters of sulfur- and nitrogen-containing substances in municipal waste water were determined. A new method was developed to determine the organic sulfur in compounds absorbed on activated carbon (AOS). The determination of dissolved organic nitrogen (DON) was calculated as the difference between total nitrogen and the sum of NH{sub 4}{sup +}-N, NO{sub 3}{sup -}-N and NO{sub 2}{sup -}N. The removal of organic substances from the inorganic matrix was only possible for standard solutions, but not for real samples. More than 60 substances contributing to the sum parameters could be identified with GC-MS and GC-AED, an most of them could be quantified. 30-70% of the sulfur-containing substances detected with GC-AED could be identified. With the GC-MS screening method 21 drugs or drug metabolites could be identified and partly quantified. Hydrophilic organic residuals were identified and quantified with high performance liquid chromatography coupled with UV- and fluorescence detectors and also with a mass detector (ESI-MS-MS). With the methods described only a small percentage of the sum of AOS and DON could be detected, although new materials for the solid phase enrichment and new analytical methods, such as HPLC-MS-MS were used. In order to get information about the degree of elimination (absorption or degradation) of different drugs in a municipal sewage plant, laboratory-scale tests under aerobic conditions were performed. A batch reactor containing drugs in environmentally relevant concentrations and a suspension of activated sludge was coupled online with HPLC

  1. Use of 125I-labeled human serum albumin for quantitation of microvascular permeability in rat skin: reevaluation of an old method for studies on substances with an enhancing effect on microvascular permeability

    1981-01-01

    A method of determining the leakage of 125I-labeled human serum albumin in the plasma into a standardized area of rat skin to study the effects of intracutaneous application of vasoactive substances on microvascular permeability, was reevaluated. The effect is expressed as a quotient (Q) between the amount of labeled albumin in the test area and that in an area injected with buffer. This calculation is simple and as reliable as more complicated expressions of activity. Within a limited dose range, linear/log dose-response curves can be obtained after application of histamine or bradykinin. Locally injected 125I-labeled human serum albumin is eliminated very slowly from rat skin and determination of the amount of radiolabeled albumin in skin after an intravenous injection therefore represents leakage from the vascular compartments. The potentialities and advantages of this method in pharmacological studies are stressed

  3. Self-reported use of novel psychoactive substances in a US nationally representative survey: Prevalence, correlates, and a call for new survey methods to prevent underreporting.

    Science.gov (United States)

    2015-11-01

    In recent years, there has been an increase in emergence and use of novel psychoactive substances (NPS) in the US and worldwide. However, there is little published epidemiological survey data estimating the prevalence of use in the US. Data on self-reported NPS use came from the National Survey of Drug Use and Health (2009-2013), a national representative sample of non-institutionalized individuals in the US. Subjects were asked to provide names of (non-traditional) drugs they used that they were not specifically asked about. We examined lifetime prevalence and sociodemographic correlates of self-reported use of new and uncommon synthetic drugs (NPS) among subjects ages 12-34-years-old. 1.2% of subjects self-reported any use of the 57 NPS we examined. Use of psychedelic tryptamines (primarily DMT) was most common, followed by psychedelic phenethylamines (e.g., 2C series) and synthetic cannabinoids. Prevalence of self-reported use of NPS increased from 2009 to 2013 and use was most common among males, whites, older subjects, those of lower income, and among those residing in cities. Lifetime use of various other illicit drugs (e.g., LSD, cocaine, ecstasy/MDMA) was highly prevalent among NPS users. This the first study reporting on use of a variety of NPS in a nationally representative US sample; however, use appears to be underreported as other national data suggest higher rates of NPS (e.g., synthetic cannabinoid) use. Developing more adaptable survey tools and systematically assessing NPS use would allow researchers to ask about hundreds of NPS and improve reporting as new drugs continue to rapidly emerge.

    A new method of radiolabelling of humic substances (HS) in the aqueous phase has been developed. Radiolabelling with the short-lived positron-emitter {sup 18}F was carried out via diazonium coupling to electron-rich aromatic residues of the humic substances. Labelling yields of up to 75% were obtained after optimization of the synthetic procedure. Introductory experimental steps were performed for testing the labelling stability of the humic substances with ultrafiltration, electrophoretic and chromatographic methods. (orig.)

    Science.gov (United States)

    Garcia-Guasch, Roser; Roigé, Jaume; Padrós, Jaume

    2012-04-01

    Anaesthesiologists have a significantly higher frequency of substance abuse by a factor of nearly 3 when compared with other physicians. This is still a current problem that must be reviewed. Many hypotheses have been formulated to explain why anaesthesiologists appear to be more susceptible to substance abuse than other medical professionals (genetic differences in sensitivity to opioids, stress, the association between chemical dependence and other psychopathology or the second-hand exposure hypothesis). Environmental exposure and sensitization may be an important risk factor in physician addiction. There is a long debate about returning to work for an anaesthetist who has been depending on opioid drugs, and recent debates are discussed. Institutional efforts have been made in many countries and physician health programmes have been developed. As drug abuse among anaesthesiologists has continued, new studies have been conducted to know the theories about susceptibility. Written substance abuse policies and controls must be taken in place and in all countries.

  20. Substance abuse and cancer.

    Science.gov (United States)

    Moussas, G I; Papadopoulou, A G

    2017-01-01

    Substance abuse is a health problem with serious psychological and psychiatric dimensions and multiple social and economic consequences. Cancer is a disease that threatens not only life and physical integrity but mental health as well. Oncology patients suffer from mental disorders in high rates, especially from depression and anxiety. The role of substance abuse in the pathogenesis of cancer is studied systematically, since there are research data supporting the mutagenic effects of certain substances. It has been supported that a possible dysregulation of the immune system is linked to the oncogenic processes induced by substances of abuse. Specifically, opioids are the first addictive substances that have been identified as oncogenic factors. However, conflicting results have been offered by experimental animal studies, which showed that opioids, such as morphine, depending on the dosage administered, may not only enhance the process of tumor growth, but also inhibit it. Additionally, research data indicate that the use of cannabis may be associated with cancer, either as an independent factor or in relation to other mutagenics, although it is not yet clear to which extent these effects may be connected to the disease, especially once the consumption of tobacco and alcohol by these patients are taken into account. However, it has been argued that certain cannabinoids may have biological -anticancer- activities which could be used therapeutically without being accompanied by the corresponding 9-tetrahydrocannabinol psychoactive effects. It is well known that alcohol is a risk factor for developing head and neck cancer, and epidemiological studies indicate that the higher the consumption of alcohol, the more mortality due to cancer increases. In addition, it is suggested that there is no safety level for alcohol consumption regarding the risk of developing cancer; that is even a minimum daily consumption is associated with the occurrence of certain types of cancer

  1. Initial findings from a mixed-methods evaluation of computer-assisted therapy for substance misuse in prisoners: Development, implementation and clinical outcomes from the ‘Breaking Free Health & Justice’ treatment and recovery programme

    examine the processes of implementation of this novel digital health programme and the various barriers and facilitators of this, including the practicalities of providing an online treatment programme in an environment in which there are multiple, complex security requirements and considerations. Additionally, the acceptability of the BFHJ programme to prisoners who may have limited experience of using online technologies was also explored. Clinical outcomes in terms of the programmes impact on substance dependence and use were also examined. Methods: In line with the Medical Research Council (MRC guidelines around development and evaluation of complex interventions (Craig et al., 2008, a mixed-methods approach was used including a qualitative study to explore the implementation of this online treatment programme within the secure prison environment, and offender perceptions of this novel, technology-enhanced approach to substance misuse treatment. In addition, quantitative data derived from a battery of standardised psychometric assessments was used to examine clinical effectiveness of BFHJ. Results: In order to meet MoJ security requirements prior to implementation, the BFHJ programme had to be reviewed and ‘white listed’ by NOMS and their security partner XMA to ensure the programme met all security, quality and information assurance processes and standards. This was a lengthy and costly process that entailed freshly developing the programme in partnership with VC experts at NOMS to ensure the programme is ‘sterile’ i.e., there are no holes in the system or links to external websites – this comprised some aspects of the programme content and resulted in some clinical techniques requiring reworking e.g., removing Google maps from one section of the programme. Themes emerging from qualitative data around offenders experiences of BFHJ illustrate its potential for use in prison settings and also to provide, for the first time, genuine continuity of care during

  4. Adaptive Differential Evolution Approach for Constrained Economic Power Dispatch with Prohibited Operating Zones

    Directory of Open Access Journals (Sweden)

    Abdellatif HAMOUDA

    2011-12-01

    Full Text Available Economic power dispatch (EPD is one of the main tools for optimal operation and planning of modern power systems. To solve effectively the EPD problem, most of the conventional calculus methods rely on the assumption that the fuel cost characteristic of a generating unit is a continuous and convex function, resulting in inaccurate dispatch. This paper presents the design and application of efficient adaptive differential evolution (ADE algorithm for the solution of the economic power dispatch problem, where the non-convex characteristics of the generators, such us prohibited operating zones and ramp rate limits of the practical generator operation are considered. The 26 bus benchmark test system with 6 units having prohibited operating zones and ramp rate limits was used for testing and validation purposes. The results obtained demonstrate the effectiveness of the proposed method for solving the non-convex economic dispatch problem.

    This report presents methods which aim at proposing a first quantification (screening) of the potential impact and risk of releases from mining installations at the scale of a drainage basin for a given period, and at refining the characterization of the radiological and/or chemical risk when a potential risk is revealed by the screening step. The screening method allows a parallel assessment of the radio-ecological risk (for the whole set of radionuclides belonging to the uranium family) and of the chemical risk associated with uranium. The refinement is based on the use of probabilistic methods. These approaches lead to the calculation of a deterministic risk index by comparing Predicted Environmental Concentrations (PECs) with Predicted No-Effect Concentrations (PNECs) in the same media

    Scholars who examine the efficacy of juvenile tobacco sales restrictions, especially the 1992 "Synar Amendment" that led all of fifty U.S. states to enact prohibitions on tobacco sales to minors, are notably divided as to impact on youth smoking. Some researchers claim that such policies have failed and ought to be abandoned (Craig & Boris, 2007; Etter, 2006; Glantz, 2002), while others insist that enforcement has indeed led to reduced tobacco use (DiFranza, 2011b; SAMHSA, 2011). The present study is the first to combine data on Synar violation rates from all states and years available since the amendment's implementation, assessing the connection to national rates of cigarette sales and youth smoking behavior. Using national data from the United States Substance Abuse and Mental Health Services Administration, the Tobacco Institute, and the Centers for Disease Control's Youth Risk Behavior Surveillance System across all U.S. states between 1996 and 2007, we employ hierarchical linear modeling to examine the connection between retailer Synar violations and youth smoking. Controlling for state-level demographic variables, results indicate that retailer violation rates are significantly associated with greater youth smoking prevalence, as well as higher overall cigarette sales. While critiques of Synar policies are substantive and should be addressed, laws prohibiting the sale of tobacco to juveniles appear to have had some degree of success. Copyright © 2015 Elsevier B.V.

    Trelagliptin succinate is a dipeptidyl peptidase IV (DPP-4) inhibitor which is used as a new long-acting drug for once-weekly treatment of type 2 diabetes mellitus (DM). In the present study, a rapid, sensitive and accurate high-performance liquid chromatography (HPLC) method was developed and validated for separation and determination of trelagliptin succinate and its eight potential process-related impurities. The chromatographic separation was achieved on a Waters Xselect CSH™ C 18 (250mm×4.6mm, 5.0μm) column. The mobile phases comprised of 0.05% trifluoroacetic acid in water as well as acetonitrile containing 0.05% trifluoroacetic acid. The compounds of interest were monitored at 224nm and 275nm. The stability-indicating capability of this method was evaluated by performing stress test studies. Trelagliptin succinate was found to degrade significantly in acid, base, oxidative and thermal stress conditions and only stable in photolytic degradation condition. The degradation products were well resolved from the main peak and its impurities. In addition, the major degradation impurities formed under acid, base, oxidative and thermal stress conditions were characterized by ultra-high-performance liquid chromatography coupled with linear ion trap-Orbitrap tandem mass spectrometry (UHPLC-LTQ-Orbitrap). The method was validated to fulfill International Conference on Harmonisation (ICH) requirements and this validation included specificity, linearity, limit of detection (LOD), limit of quantification (LOQ), accuracy, precision and robustness. The developed method in this study could be applied for routine quality control analysis of trelagliptin succinate tablets, since there is no official monograph. Copyright © 2017 Elsevier B.V.

    A simple, rapid, and inexpensive extraction method for carotenoids and other non-polar compounds present in phototrophic bacteria has been developed. The method, which has been extensively tested on the phototrophic purple non-sulphur bacterium Rhodospirillum rubrum, is suitable for extracting large numbers of samples, which is common in systems biology studies, and yields material suitable for subsequent analysis using HPLC and mass spectroscopy. The procedure is particularly suitable for carotenoids and other terpenoids, including quinones, bacteriochlorophyll a and bacteriopheophytin a, and is also useful for the analysis of polar phospholipids. The extraction procedure requires only a single step extraction with a hexane/methanol/water mixture, followed by HPLC using a Spherisorb C18 column, with a mobile phase consisting of acetone-water and a non-linear gradient of 50%-100% acetone. The method was employed for examining the carotenoid composition observed during microaerophilic growth of R. rubrum strains, and was able to determine 18 carotenoids, 4 isoprenoid-quinones, bacteriochlorophyll a and bacteriopheophytin a as well as four different phosphatidylglycerol species of different acyl chain compositions. The analytical procedure was used to examine the dynamics of carotenoid biosynthesis in the major and minor pathways operating simultaneously in a carotenoid biosynthesis mutant of R. rubrum.

    A fast and sensitive method for simultaneous determination of 18 traditional and 6 alternative per- and polyfluoroalkyl substances (PFASs) using solid-liquid extraction (SLE), off-line clean-up using activated carbon and on-line solid phase extraction-ultrahigh performance liquid chromatography-time-of-flight-mass spectrometry (on-line SPE-UHPLC-TOF-MS) was developed. The extraction efficiency was studied and recoveries in range the 58-114% were obtained. Extraction and injection volumes were also optimized to 2mL and 400μL, respectively. The method was validated by spiking dust from a vacuum cleaner bag that had been found to contain low levels of the PFASs in focus. Low method detection limits (MDLs) and method quantification limits (MQLs) in the range 0.008-0.846ngg(-1) and 0.027-2.820ngg(-1) were obtained, respectively. For most of the PFASs, the accuracies were between 70 and 125% in the range from 2 to100ngg(-1) dust. Intra-day and inter-day precisions were in general well below 30%. Analysis of a Standard Reference Material (SRM 2585) showed high accordance with results obtained by other laboratories. Finally, the method was applied to seven indoor dust samples, and PFAS concentrations in the range 0.02-132ngg(-1) were found. The highest median concentrations were observed for some of the alternative PFASs, such as 6:2-diPAP (25ngg(-1)), 8:2-diPAP (49ngg(-1)), and PFOPA (23ngg(-1)), illustrating the importance of inclusion of new PFASs in the analytical methods.

    Drug use in Malaysia remains a significant public health and social problem despite implementation of harsh punitive drug policies such as forcibly placing suspected drug users into compulsory drug detention centers (CDDCs). Following criticism over human right violations in CDDCs, Malaysia has begun to transition towards voluntary drug treatment centers known as Cure & Care (C&C) centers. To best serve the needs of regional C&C centers, data on drug use are essential among patients accessing treatment. Using a mixed-methods approach, the authors examined pretreatment drug use characteristics and experiences with addiction treatment among C&C patients in Kelantan-a religiously conservative state in northeast Malaysia with high prevalence of drug use but where limited data are available on drug use patterns. A mixed-methods study utilizing surveys (n = 96) and semistructured interviews (n = 20) was conducted among a convenience sample of inpatients and outpatients at the Pengkalan Chepa C&C Center in Kelantan. Survey results showed that 89.6% of participants met screening criteria for moderate to severe addiction severity. Nearly 90% reported lifetime illicit amphetamine (syabu, meth, ice, and pil kuda) use, followed by alcohol (60.4%) and opioids (52.1%). Qualitative results pointed to the powerful influence of peer networks in drug initiation and relapse, and the positive effect of the C&C center on drug rehabilitation. The drug use profile of the Kelantan C&C center enrollees shows extensive pretreatment amphetamine use, polysubstance use, and injection drug use, including high-risk behaviors such as sharing needles, syringes, and containers. Evidence points to the need for integration of social support-oriented practices and behavioral interventions into the rehabilitation of drug users in this region.

    2002-01-01

    On July 31, 2001, the U.S. House of Representatives passed The Human Cloning Prohibition Act of 2001. The legislation proposes a complete ban on somatic cell nuclear transfer to create cloned human embryos; it threatens transgressors with criminal punishment and civil fines. House Bill 2505 is the first human cloning prohibition to pass either chamber of Congress. This note argues that the bill is unconstitutionally vague and inconsistent with the Supreme Court's recent Commerce Clause jurisprudence.

  13. The toxicology of cannabis and cannabis prohibition.

    Grotenhermen, Franjo

    2007-08-01

    The acute side effects caused by cannabis use are mainly related to psyche and cognition, and to circulation. Euphoria, anxiety, changes in sensory perception, impairment of memory and psychomotor performance are common effects after a dose is taken that exceeds an individually variable threshold. Cannabis consumption may increase heart rate and change blood pressure, which may have serious consequences in people with heart disease. Effects of chronic use may be induction of psychosis and development of dependency to the drug. Effects on cognitive abilities seem to be reversible after abstinence, except possibly in very heavy users. Cannabis exposure in utero may have negative consequences on brain development with subtle impairment of cognitive abilities in later life. Consequences of cannabis smoking may be similar to those of tobacco smoking and should be avoided. Use by young people has more detrimental effects than use by adults. There appear to be promising therapeutic uses of cannabis for a range of indications. Use of moderate doses in a therapeutic context is usually not associated with severe side effects. Current prohibition on cannabis use may also have harmful side effects for the individual and the society, while having little influence on prevalence of use. Harm is greatest for seriously ill people who may benefit from a treatment with cannabis. This makes it difficult to justify criminal penalties against patients.

  17. Absorption and translocation of lead by plants: a contribution to the application of the method of radioactive indicators in the investigation of the change of substance

    1923-01-01

    The assimilation of lead from lead nitrate solutions by Vicia Faba has been investigated. A radioactive isotope of lead was mixed with the lead nitrate, and the amount of lead taken up was determined after ignition from the radioactive intensity of the ash of the various parts. This method makes possible the determination of exceedingly small amounts of assimilated lead. Whereas 0-3% of the lead is taken up by the root from 200 cc. of a 10/sup -1/ N lead nitrate solution in the course of 24 hours, 60% of the lead content of a 10/sup -1/ N lead nitrate solution in the course of 24 hours, 60% of the lead content of a 10/sup -6/ N solution is taken up in the same time. The leaves show a lead content of only a few hundredths or thousandths of 1% of the amount of lead present in the solution. The assimilated (radioactive) lead can be displaced by introduction of the plant containing lead into another lead solution, whereby inactive lead atoms now take the place of the radioactive ones. From this it follows that the lead is not combined with carbon within the plant, but that it exists in the form of a dissociable salt which is soluble with difficulty. Even after 24 hours, a 10/sup -1/ N solution of a lead salt produces toxic effects on the plant, while more dilute solutions do not. Lead belongs to the least poisonous of the heavy metals. 9 references.

    The European Water Framework Directive require to the EU Member States the knowledge of the priority hazardous pollutant contamination levels. Regional basin management plans (according to Italian laws D.Lgs 152/99 and to D.M. 367/03) generally include a review about the status of water contamination to respond to the Eu legislation prescriptions. However, since the actual monitoring activity of the water contamination is expensive and also extremely difficult in terms of analytical sensitivity, the most of these reviews has been prepared by using indirect emission coefficient estimates derived form literature. It is well known that such emission coefficients have been rarely proved fully reliable; moreover such an approach gives no information about the variability affecting the emission estimates. Aim of this work was to use the data contained into the emission EPER-INES database, european database which contains the IPPC Directive emission declarations, to define emission coefficients more reliable than literature coefficients. The presented results, even though based on a limited number of observations and referring the most only to heavy metals, confirm the scarce affidability of the emission factor method and show remarkable discrepancies (mostly under- but also over-estimations of about ten-fold) of these emission estimates from the actual emission data of the IPPC declarations. These results allow also to evaluate the not negligible variability that affects the definition of emission coefficients [it

    With the rapid development and wide application of traditional Chinese medicine injection (TCMI), a number of adverse events of some TCMIs have incessantly been reported and have drawn broad attention in recent years. Establishing effective and practical analytical methods for safety evaluation and quality control of TCMI can help to improve the safety of TCMIs in clinical applications. In this study, a sensitive and rapid high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method has been developed and validated for the quantitative determination of potentially harmful substance 5,5'-oxydimethylenebis (2-furfural, OMBF) in TCMI samples. Chromatographic separation was performed on a C18 reversed-phase column (150 mm × 2.1 mm, 5 µm) by gradient elution, using methanol-water containing 0.1% formic acid as mobile phase at the flow rate of 0.3 mL/min. MS/MS detection was performed on a triple quadrupole mass spectrometer with positive electrospray ionization in the multiple reaction-monitoring mode. The method was sensitive with a limit of quantification of 0.3 ng/mL and linear over the range of 0.3-30 ng/mL ( r =0.9998). Intra- and inter-day precision for analyte was <9.52% RSD with recoveries in the range 88.0-109.67% at three concentration levels. The validated method was successfully applied to quantitatively determine the compound OMBF in TCMIs and glucose injections. Our study indicates that this method is simple, sensitive, practicable and reliable, and could be applied for safety evaluation and quality control of TCMIs and glucose injections.

    To summarize results of studies that estimate the social costs of alcohol, tobacco, and illicit drug abuse in Russia. The purpose of these studies was to inform policymakers about the real economic burden of risky behaviors and to provide conditions for evidence-based and well-informed decision making in this area. The cost-of-illness method was applied to estimate the social cost of substance abuse. The intangible cost was not included in estimation. A prevalence-based approach was applied to estimate the tangible cost. For the estimation of direct costs, a top-down method was used. Indirect costs were estimated using two methods: the human capital and the friction cost. In 2008, the social cost of substance abuse in Russia comprised 677.2 billion rubles if the friction cost method is applied and 1965.9 billion rubles if the human capital method is used. The social cost of substance abuse is defined to the greatest extent by alcohol consumption, comprising about 45% of the economic burden. Illicit drug use comprises about 30% of the economic burden and tobacco consumption 25%. The results of economic studies demonstrated that psychoactive substances impose a considerable economic burden on society. Analysis of the substance abuse social cost pattern shows that the main losses that society bears because of these behavioral risk factors fall outside the health care system and lay in other sectors of the economy such as social care, law enforcement, and productivity losses.

  6. Should Sabbath Prohibitions Be Overridden to Provide Emotional Support to a Sick Relative?

    Directory of Open Access Journals (Sweden)

    2016-07-01

    Full Text Available Background There is a consensus among the halachic authorities that life-saving actions override Sabbath prohibitions. They are painstaking in securing that the sanctity of the Sabbath is maintained but that not a single life be lost. Objective This manuscript examines if and when a relative’s presence at the bedside of a seriously ill individual is potentially life-saving against the backdrop of the scientific literature. It specifically addresses the permissibility of traveling in a motorized vehicle, generally prohibited on the Sabbath, to be with one’s relative in hospital for the provision of emotional support. Methods Discourse of the halachic issues in the context of the scientific literature. Results Stress, mental or physical, has been determined as a potentially life-threatening condition in many disease entities. The literature attests to both the patient’s and the professionals’ perception of the curative potential of the presence of loved ones by advocating for the patient and relieving stress in the hospital experience. Emotional support from a loved one is perceived by some patients as vital to survival. There is halachic consensus that a patient’s perception of the emotional need for a relative’s presence is sufficient to permit overriding rabbinic prohibitions. Torah prohibitions, which may be overridden for medical needs, may be overridden for emotional support, providing a health professional or family member attests to the fulfilment of this specific need as diminishing the danger to the patient’s life. In certain cases, the latter contingency is unnecessary. Conclusions Emotional support has an impact on the patient’s health status; the degree to which its impact is strong enough to save life is still being studied. As more data from scientific studies emerge, they may be relevant to sharpening the halachic rulings with respect to the issue at hand.

    Full Text Available Background. Substance-induced psychotic disorder (SIPD is a diagnosis constructed to distinguish substance-induced psychotic states from primary psychotic disorders. A number of studies have compared SIPD persons with primary psychotic patients, but there is little data on what differentiates substance use disorder (SUD individuals with and without SIPD. Here, we compared psychopathology, sociodemographic variables, and substance use characteristics between SUD patients with and without SIPD. Methods. A retrospective chart review was conducted on newly admitted patients at a rehabilitation centre between 2007 and 2012. Results. Of the 379 patients included in the study, 5% were diagnosed with SIPD n=19 and 95% were diagnosed with SUDs without SIPD n=360. More SIPD patients reported using cannabis and psychostimulants, and fewer SIPD patients reported using alcohol than SUDs patients without SIPD. SIPD patients scored higher on the “schizophrenia nuclear symptoms” dimension of the SCL-90R psychoticism scale and exhibited more ClusterB personality traits than SUD patients without SIPD. Discussion. These data are consistent with previous studies suggesting that psychopathology, substance type, and sociodemographic variables play important role in the development of SIPD. More importantly, the results highlight the need for paying greater attention to the types of self-reported psychotic symptoms during the assessment of psychotomimetic effects associated with psychoactive substances.

    Full Text Available Background: Harm ratings of substances help in understanding the perception toward substance use and formulating policies. Evidence of such harm ratings by substance users and their caregivers provides a clearer perspective of those who experience and observe such harm closely. Materials and Methods: Substance users and their caregivers were recruited from the Drug De-addiction and Treatment Centre of PGIMER, Chandigarh. Sociodemographic details of the subjects were noted. The subjects were then asked to rate a list of psychoactive preparations according to the harms they thought the preparation caused. The list of substances was developed taking into consideration substance commonly encountered in the geographical area. The harm ratings were transformed on a scale of 0-100. Results: All subjects were males and majority of them were educated above 10 th standard, were not employed and belonged to urban background. Most of them had taken psychoactive substances in their lifetimes but were currently abstinent. Most of the subjects endorsed intravenous drugs as the most harmful, followed by heroin. Beer and chewable tobacco considered the least harmful substances. Greater degree of education was associated with lower harm rankings for heroin, cannabis, dextropropoxyphene, and raw opium; while urban residence was associated with greater harm ratings for cannabis and raw opium. Differences in the harms were perceived for different preparations of the same active compound for alcohol and nicotine. Conclusion: Harm ratings of substances can be a useful guide while formulating policies and allocating resources. Need for further research extending this pilot study is emphasized.

    Full Text Available Background. Youth populations are vulnerable to substance use particularly in developing countries where circumstances may be favorable for it. There is no published data on substance use among the youth in Sudan other than on tobacco use. Objectives. The aim of this study was to investigate the prevalence, circumstances, and factors associated with substance use. Methods. An institution-based survey was conducted on a sample of 500 students. Data was collected using a questionnaire designed by the WHO for student drug surveys and analyzed using IBM SPSS version 20. Results. The overall prevalence of substance use is 31%. The current prevalence of tobacco, cannabis, alcohol, amphetamines, tranquilizers, inhalants, opiates, cocaine, and heroin use was 13.7%, 4.9%, 2.7%, 2.4%, 3.2%, 1%, 1.2%, 0.7%, and 0.5%, respectively. Curiosity (33.1% was the main reason for initiation of substance use. The main adverse effects reported were health problems (19.7% and theft (19.7%. Peers (40.9% were the prime source of substance use. On multivariate analysis, male sex was the principle predictor for substance use (AOR: 5.55; 95% CI: 3.38, 9.17. Conclusion. Strategies to control substance use should encompass the role of the university and parents in observing and providing education to improve awareness of substances and their consequences.

  10. Adolescent Suicidal Behavior and Substance Use: Developmental Mechanisms

    Directory of Open Access Journals (Sweden)

    Donald M. Dougherty

    2008-01-01

    Full Text Available Adolescent suicidal behaviors and substance use are disturbingly common. Research suggests overlap of some of the etiological mechanisms for both adolescent suicidal behavior and substance use, yet clear understanding of the complex relations between these behaviors and their causal underpinnings is lacking. A growing body of evidence and a diathesis model (Mann et al. 1999; Mann, 2003 highlight the importance of impulse control as a proximal risk factor for adolescent suicidal and substance use behaviors. This literature review extends current theory on the relationships between adolescent suicidal behavior and substance use by: (1 examining how, when, and to what extent adolescent development is affected by poor impulse control, stressful life events, substance use behavior, and biological factors; (2 presenting proposed causal mechanisms by which these risk factors interact to increase risk for suicidal behaviors and substance use; and (3 proposing specific new hypotheses to extend the diathesis model to adolescents at risk for suicide and substance use. More specifically, new hypotheses are presented that predict bidirectional relationships between stressful life events and genetic markers of 5-HT dysregulation; substance use behavior and impulsivity; and substance use behavior and suicide attempts. The importance of distinguishing between different developmental trajectories of suicidal and substance use behaviors, and the effects of specific risk and protective mechanisms are discussed. Use of new statistical approaches that provide for the comparison of latent growth curves and latent class models is recommended to identify differences in developmental trajectories of suicidal behavior and substance use. Knowledge gained from these prospective longitudinal methods should lead to greater understanding on the timing, duration, and extent to which specific risk and protective factors influence the outcomes of suicidal behavior and substance

    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.

    Full Text Available Background: Drug taking behavior and drug dependence is a multi-factorial disorder. Personality is a very important determining factor of drug dependence. Objectives: To find out the possible relationship between personality traits and substance use disorders. Methods: This was a descriptive, cross-sectional and case-control study conducted in the department of Psychiatry of Bangabandhu Sheikh Mujib Medical University and Central Drug Addiction Treatment Center, Dhaka for a period of one year (January 2005 to December 2005. From five hundred respondents, 250 had the history of substance use disorders selected as case, and equal number were age, sex, habitat and economic background matched controls were taken. Personality traits of both cases and control were measured by applying Eysenck Personality Questionnaire. Results: Mean ± SD psychoticism (8.42±3 vs 4.33±1.8, Neuroticism (11.89±2.3 vs 9.83±2 were significantly higher (P<0.01 in cases than controls. It was found that psychoticism was 2.3 times and neurticism was 1.7 times higher in substance users than that of controls. There were no significant differences of mean distribution of extroversion and lie scales among the cases & controls. This study also revealed that, there was no significant relationship between personality traits and different variables related to substance use except that psychoticism was significantly higher in those substance users who had have positive history of troubles with law than those having no history of trouble with law (8.82±3.2 & 7.95±2.7 respectively. Conclusion: Personality traits may have an influence on persons with substance use disorder which detoriates quality of life.

  15. Waste management and the land disposal restriction storage prohibition

    International Nuclear Information System (INIS)

    1992-05-01

    RCRA Sect. 3004(j) prohibits storage of wastes that have been prohibited from land disposal, unless that storage is for the purpose of accumulating sufficient quantities of hazardous wastes to facilitate proper recovery, treatment, or disposal. This requirement was incorporated as part of the Land Disposal Restriction (LDR) regulations. Under the LDR storage prohibition, facilities may only store restricted wastes in containers and tanks. As stated in the Third LDR rule, storage of prohibited waste is only allowed in non-land based storage units since land-based storage is a form of disposal. The EPA has recognized that generators and storers of radioactive mixed waste (RMW) may find it impossible to comply with storage prohibition in cases where no available treatment capacity exists. Additionally, under the current regulatory interpretation, there is no provision that would allow for storage of wastes for which treatment capacity and capability are not available, even where capacity is legitimately being developed. Under the LDR program, restricted wastes that are disposed of, or placed into storage before an LDR effective date, are not subject to the LDR requirements. However, if such wastes are removed from a storage or disposal site after the effective date, such wastes would be subject to LDR requirements. The purpose of this information brief is to clarify what waste management practices constitute removal from storage

    Purpose: To easily solidify radioactive substances adhering to the surfaces of solid wastes without scattering in the circumference by paints, and further to reduce surface contamination concentrations. Constitution: Solid wastes are placed on a hanging plate, and dipped in paints within a paint dipping treatment tank installed at the lower part of a treatment tank by means of a monorail hoist, and the surfaces of said solid wastes are coated with paints, thereby to solidify the radioactivity on the surfaces of the solid wastes. After dipping, the solid wastes are suspended up to a paint spraying tank to dry the paints. After drying, non-contaminated paints are atomized to apply through an atomizing tube onto the solid wastes. After drying the atomized paints, the solid wastes are carried outside the treatment tank by means of the monorail hoist. (Yoshino, Y.)

    in large urban regions of Brazil in 2005. The data were collected by means of questionnaires. The chi-square automatic interaction classification tree technique was used to study the use of condoms among interviewees of both sexes and other contraceptive methods among women, at the time of the last vaginal sexual intercourse. RESULTS: Among young and middle-aged adults of both sexes and young men in stable relationships, condom use was less frequent among those who said they used psychoactive substances (alcohol and/or illegal drugs. The possible modulating effect of psychoactive substances on contraceptive practices among mature women seems to be more straightforward, compared to the more subtle effects observed among younger women, for whom the different social classes they belonged to seemed to play a more important role. CONCLUSIONS: Despite the limitations resulting from an exploratory study, the fact that this was a representative sample of the urban population of Brazil and not from vulnerable populations, reinforces the need to implement integrated public policies directed towards the general population, with regard to preventing drug consumption, alcohol abuse, sexually transmitted infections, HIV/AIDS and unwanted pregnancy and promoting sexual and reproductive health.

Data were collected by a self-administered questionnaire concerning general and professional characteristics and the consumption of psychoactive substances (psychoactive drugs, tobacco, alcohol and cannabis) during the professional medical visit. We identified consumer profiles with a hierarchical ascendant classification as statistical method. We underlined five profiles associated with psychoactive substance consumption: (1) alcohol consumers in the workplace were sales engineers satisfied with their employment, (2) alcohol consumers after their work were not satisfied with their lives, (3) cannabis consumers were men professionally satisfied but suffering from job insecurity, (4) smokers were workers with professional responsibilities under time pressure, and finally (5) poly-consumers had strong professional constraints. This study guides occupational physicians on psychoactive substances consumption among a worker population. © 2011 Société Française de Pharmacologie et de Thérapeutique.

  4. An action plan for radioactive substances regulation

    International Nuclear Information System (INIS)

    1998-01-01

    This document sets out an action plan for the Agency's Radioactive Substances Regulation function. Our vision is to secure continuous improvement in the protection of the public and the environment from the harmful effects of radioactive substances. Radioactive Substances Regulation will work with others to realise this vision and contribute to the Agency's role in achieving sustainable development. We will also work to ensure that the Agency achieves its objectives in an efficient, consistent and integrated way. The main elements of our Action Plan are as follows: establishing indicators of sustainability and the means and methods of monitoring them; establishing performance indicators and a programme of targets and objectives to be achieved; establishing a database of all premises subject to RSA93 and to use it for work planning, resource targeting, and improvement to radioactive waste management; provision of systems of procedures and technical guidance to ensure nationally consistent and cost- effective regulation; establishing systems to audit the implementation of the procedures and guidance; ensuring quality of regulation by defining technical competencies of inspectors and the training programmes to secure them; an R and D programme targeted on improving radioactive waste management and radioactive substances regulation; and full and effective participation in development of national policy

  8. Substance Use Stigma: Reliability and validity of a theory-based scale for substance-using populations*

    Science.gov (United States)

    Smith, Laramie R.; Earnshaw, Valerie A.; Copenhaver, Michael M.; Cunningham, Chinazo O.

    2016-01-01

    Background Substance use disorders consistently rank among the most stigmatized conditions worldwide. Thus, substance use stigma fosters health inequities among persons with substance use disorders and remains a key barrier to successful screening and treatment efforts. Current efforts to measure substance use stigma are limited. This study aims to advance measurement efforts by drawing on stigma theory to develop and evaluate the Substance Use Stigma Mechanisms Scale (SU-SMS). The SU-SMS was designed to capture enacted, anticipated, and internalized substance use stigma mechanisms among persons with current and past substance use disorders, and distinguish between key stigma sources most likely to impact this target population. Methods This study was a cross-sectional evaluation of the validity, reliability, and generalizability of the SU-SMS across two independent samples with diverse substance use and treatment histories. Results Findings support the structural and construct validity of the SU-SMS, suggesting the scale was able to capture enacted, anticipated, and internalized stigma as distinct stigma experiences. It also further differentiated between two distinct stigma sources (family and healthcare providers). Analysis of these mechanisms and psychosocial metrics suggests that the scale is also associated with other health-related outcomes. Furthermore, the SU-SMS demonstrated high levels of internal reliability and generalizability across two independent samples of persons with diverse substance use disorders and treatment histories. Conclusion The SU-SMS may serve as a valuable tool for better understanding the processes through which substance use stigma serves to undermine key health behaviors and outcomes among persons with substance use disorders.

  18. Alexithymia in Egyptian Substance Abusers.

    Science.gov (United States)

    El Rasheed, Amany Haroun

    2001-03-01

    Alexithymia is thought of as a trait that predisposes to drug abuse. Moreover, it is suggested to be related to type of the substance abused, with the worst-case scenario including a worse prognosis as well as tendency to relapse or even not to seek treatment at all. To address this important subject in Egyptian patients, a sample of 200 Egyptian substance abusers was randomly selected from inpatients in the Institute of Psychiatry, Ain Shams University, Egypt. The study also included 200 group-matched controls. DSM-IV criteria were used for assessment of substance use disorders, and toxicologic urine analysis was used to confirm the substances of abuse. Toronto Alexithymia Scale (TAS)-Arabic version was used for assessment of alexithymia. It was found that alexithymia was significantly more prevalent in the substance use disorders group as compared to healthy controls. It was also found that among the substance use disorders group, alexithymics reported more polysubstance abuse, more opiate use (other than heroin IV), lower numbers of hospitalizations, lower numbers of reported relapses, and a lower tendency to relapse as a result of internal cues compared to patients without alexithymia. Statistically significant associations were also found between alexithymia and more benzodiazepine abuse and nonpersistence in treatment. The results suggest that alexithymia should be targeted in a treatment setting for substance use disorders.

  19. Definition of Substance and Non-substance Addiction.

    Zou, Zhiling; Wang, Huijun; d'Oleire Uquillas, Federico; Wang, Xiaomei; Ding, Jianrui; Chen, Hong

    2017-01-01

    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.

  20. Role of parenting styles in adolescent substance use: results from a Swedish longitudinal cohort study

    Science.gov (United States)

    Berge, J; Sundell, K; Öjehagen, A; Håkansson, A

    2016-01-01

    Objective Adolescent substance use is an area of concern because early substance use is associated with a higher risk of adverse outcomes. Parenting style, defined as the general style of parenting, as well as substance-specific parenting practices may influence children's substance use behaviour. The present study aims to probe the impact of parenting style on adolescent substance use. Method A cohort of 1268 adolescents (48% girls), aged 12–13 years at baseline, from 21 junior high schools was assessed in the first semester of junior high school, and then again in the last semester of the 9th grade, 32 months later. Parenting style, operationalised as a fourfold classification of parenting styles, including established risk factors for adolescent substance use, were measured at baseline. Results Neglectful parenting style was associated with worse substance use outcomes across all substances. After adjusting for other proximal risk factors in multivariate analyses, parenting style was found to be unrelated to substance use outcomes with one exception: authoritative parenting style was associated with less frequent drinking. Association with deviant peers, delinquent behaviour, provision of alcohol by parents, and previous use of other substances were associated with substance use outcomes at follow-up. Conclusions The results of the present study indicate that parenting style may be less important for adolescent substance use outcomes than what has previously been assumed, and that association with deviant peers and delinquent behaviour may be more important for adolescent substance use outcomes than general parenting style.

  1. The existing state of sewage sludge containing radioactive substances

    International Nuclear Information System (INIS)

    Shirasaki, Makoto; Hisaoka, Natsuki

    2012-01-01

    Radioactive substances were discharged over a wide range from the accident of the Fukushima Daiichi Nuclear Station of Tokyo Electric Power Company. As a result, in sewer system, especially in the combined sewer system that jointly collects rainwater and sewage, radioactive substances accumulated on the surface of urban areas were transferred together with rainwater to sewage plants and accumulated there. In the process of further treatment, radioactive substances were transferred to and concentrated in sewage sludge, and a high concentration of radioactive substances were detected in incineration ash. For this reason, some sewage plants still continuously store dewatered sludge, incinerator ash, etc. This paper introduces the current state of waste treatment from the published data from each local government in Tohoku and Kanto districts. As for the sewer, which is essential as a lifeline, the Ministry of Land, Infrastructure, Transport and Tourism, together with the Japan Sewage Works Association, established 'Investigative Commission on Radioactive Substance Countermeasures in Sewerage System.' This group grasped the damage situation due to radioactive substances, and summarized the measures to be taken by sewage managers, such as the storage method for sewage sludge containing radioactive substances as well as the method for the volume reduction of sewage sludge.

  2. New DEA rules expand options for controlled substance disposal.

    Science.gov (United States)

    Peterson, David M

    2015-03-01

    Prescription drug abuse and overdose are rapidly growing problems in the United States. The United States federal Disposal of Controlled Substances Rule became effective 9 October 2014, implementing the Secure and Responsible Drug Disposal Act of 2010 (Disposal Act). These regulations target escalating prescription drug misuse by reducing accumulation of unused controlled substances that may be abused, diverted or accidentally ingested. Clinical areas that can now participate in collecting unused controlled substances include retail pharmacies, hospitals or clinics with an onsite pharmacy, and narcotic treatment programs. Collection methods include placing a controlled substance collection receptacle or instituting a mail-back program. Because prompt onsite destruction of collected items is required of mail-back programs, collection receptacles are more likely to be used in clinical areas. Retail pharmacies and hospitals or clinics with an onsite pharmacy may also place and maintain collection receptacles at long-term care facilities. The Act and Rule are intended to increase controlled substance disposal methods and expand local involvement in collection of unused controlled substances. Potential barriers to participating in controlled substance collection include acquisition of suitable collection receptacles and liners, lack of available space meeting the necessary criteria, lack of employee time for verification and inventory requirements, and program costs.

    Full Text Available Introduction: stroke in recreational substance users can be an indirect complication, like endocarditis and cardio embolism in parenteral drug users. 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. Ephedrine and pseudo ephedrine are present in decongestants and bronchodilators and induce headache, tachyarrhythmia, hypertensive emergency, and hemorrhagic and occlusive stroke.

    2014-01-01

    The aim of this study was to summarise the scientific evidence on the prevalence of psychoactive substance use and on the factors associated with their intake among truck drivers. A systematic review was performed in the databases PubMed, Scientific Electronic Library Online, Latin American and Caribbean Health Sciences, and Cochrane and 36 cross-sectional studies were identified with quantitative results about the use of psychoactive substances by truck drivers. Out of these, 28 were carried out in countries with large land areas and 23 obtained their information through self-reporting. The most frequently studied substances were alcohol (n=25), amphetamines (n=17), marijuana (n=16) and cocaine (n=13). The prevalence of the use of these substances greatly varied: alcohol (0.1-91.0%); amphetamines (0.2-82.5%), marijuana (0.2-29.9%), cocaine (0.1-8.3%). The frequency of substance use was lower in studies that investigated the presence of these substances in biological samples than in those based on self-reported use. In 12 studies that evaluated factors associated with the intake of psychoactive substances, the following stood out: younger age, higher income, longer trips, alcohol consumption, driving in the night shift, travelling interstate routes, long or short sleep, fewer hours of rest, little experience of the driver, connection with small and medium sized companies, income below levels determined by labour agreements, productivity-based earnings and prior involvement in accidents. The frequency of psychoactive substance use by truck drivers seems to be high, although that greatly varies according to the type of substance and the method of collecting the information. The use of these substances was mainly associated with indicators of poor working conditions.

    Full Text Available Introduction: The use of psychoactive substances by the student population has been the object of various studies in Brazil. Objective: To determine the prevalence of substance use among students. Methods: Quantitative study with a closed questionnaire based on standardized assessment instruments was developed. It consists of questions related to types of psychoactive substance use, abuse, frequency and duration of use, self-criticism regarding the use, consequences of use in relation to health, and misdemeanors committed under the influence of psychoactive substances. The sample included the participation of 268 students. A total of 183 (68.3% questionnaires were analyzed, and only those with positive result for substance abuse at some point in life, the remainder, 85 (31% questionnaires, had negative responses to psychoactive substances. Results: Students’ responses to the two years surveyed indicated that the first psychoactive substance used was alcohol (77.9%, followed by tobacco use (10.9%, and marijuana (7.6%. Of the students surveyed, 145 (79.2% answered that still make use of psychoactive substances, and the current frequency of use varies from one or more times per week. When asked about the possibility of being or becoming drug addicts, 169 (92.3% responded that they are not or will not become dependent. Conclusion: The results indicate the high rate of substance use among college students surveyed, and point to their contradiction to consider such psychoactive substances harmful to their health.

    The anti-bacterial effect of 13 new commercially manufactured disinfectant substances on P. aeruginosa strain was studied. The substances tested represent 9 quaternary ammonium salts QAT and 4 combined QAT with other ingredients. The antimicrobial efficacy was characterised by influencing the growth and reproduction of bacterial cells expressed either by MIC and ED 50 as well as and ED 50 , as well as by the inhibition of incorporation rate of incorporation rate of [ 14 C] adenine and [ 14 C] leucine. The method of inhibition of [ 14 C] precursors is suitable as one from possible evaluation criterion on anti-bacterial efficacy of synthetic disinfectant substances. (authors)

    For many teenagers the time of growing up is a period of trying prohibited substances. Nowadays apart from alcohol and tobacco new designed, psychoactive substances known as "smart drugs" or "legal highs" are available. Intensive development of their market is taking place in the last few years which is difficult to overcome by regulations only. Toxicological tests used now are not able to detect the presence of many such substances in the body. Designer drugs cause the interest of young people even from small towns and many times taking them give effects requiring medical help. Caffeine is also a psychoactive substance but depending on the dose it can have positive or detrimental effect. Recently there are more and more products with caffeine, especially drinks and dietary supplements, what can cause the increase of consumption of caffeine. Children are particularly exposed to the adverse effect of high consumption of caffeine because of their small body weight and development of the central nervous system. This article presents actual data about the market of designer drugs, frequency of using them, consumption of caffeine by children and teenagers and about the impact of these substances on the organism.

    Objective: Research has documented that sexual minorities are at greater risk for substance use than heterosexuals. However, there are limited studies and mixed findings when investigating these health disparities among racial and ethnic minority samples. We used an intersectionality framework to examine disparities in lifetime substance use problems between heterosexual and sexual minority men and women and within sexual minority groups among a racially diverse sample. Method: A nonprobability sample of heterosexual (n = 1,091) and sexual minority (n = 1,465) patients from an urban community health center ranged in age from 18 to 72 years. Participants completed a brief patient survey and reported demographic information and history of lifetime substance use problems. Logistic regressions analyses were used to examine interactions between and among sexual orientation, gender, and race. Results: We found a significant three-way interaction among sexual orientation, gender, and race. Sexual minorities had a greater risk of self-reported lifetime substance use problems than heterosexuals, with nuanced gender and racial differences. Of greatest note, sexual minority women of color had greater risks than heterosexual women of color and than White sexual minority women. Sexual minority men of color did not differ in their risk when compared with heterosexual men of color, and they had lower risk than White sexual minority men. Conclusions: The results of this study demonstrate that an intersectionality framework is crucial to clearly identify lifetime substance use disparities between racially diverse sexual minority and heterosexual men and women. Future research, treatment, and policy should use intersectionality approaches when addressing substance use disparities. PMID:24411810

  14. Negative attributions towards people with substance use disorders in South Africa: Variation across substances and by gender

    Full Text Available Abstract Background Little research has examined attitudes towards people who use substances in low and middle income countries (LMIC. Therefore, the present study examined the attributions made by the general South African population about people who use substances and whether these attributions differ by the type of substance being used, the gender of the person using the substance, or the characteristics of the person making the attribution. Method A convenience sample of 868 members of the general public was obtained through street-intercept methods. One of 8 vignettes portraying alcohol, cannabis, methamphetamine or heroin, with either a male or female as the protagonist was presented to each respondent. Respondents’ attitudes towards the specific cases were investigated. Results Respondents held equally negative views of the presented substances, with the exception of the cannabis vignette which was considered significantly less “dangerous” than the alcohol vignette. Respondents were more likely to offer “help” to women who use alcohol, but more likely to suggest “coercion into treatment” for men. Individuals who scored higher on the ASSIST were more likely to hold negative attitudes towards substance users and black African respondents were more likely to offer help to individuals who use substances. Conclusion The stigma associated with substance use in South Africa is high and not necessarily dependent on the drug of choice. However, a range of factors, including gender of the substance user, and ethnicity of the rater, may impact on stigma. Interventions designed to strengthen mental health literacy and gender-focused anti-stigma campaigns may have the potential to increase treatment seeking behaviour.

    The use of performance enhancing drugs in sports is prohibited. For the detection of misuse of such substances gas chromatography or liquid chromatography coupled to mass spectrometry are the most frequently used detection techniques. In this work the development and validation of a fast gas chromatography tandem mass spectrometric method for the detection of a wide range of doping agents is described. The method can determine 13 endogenous steroids (the steroid profile), 19-norandrosterone, salbutamol and 11-nor-Δ9-tetrahydrocannabinol.9carboxylic acid in the applicable ranges and to detect qualitatively over 140 substances in accordance with the minimum required performance levels of the World Anti-Doping Agency in 1ml of urine. The classes of substances included in the method are anabolic steroids, β2-agonists, stimulants, narcotics, hormone antagonists and modulators and beta-blockers. Moreover, using a short capillary column and hydrogen as a carrier gas the run time of the method is less than 8min. Copyright © 2010 Elsevier B.V. All rights reserved.

  19. Adolescent substance abuse. Assessment in the office.

    There are no gold-standard tests for evaluating a teen suspected of abusing substances. Awareness of the high prevalence of substance abuse in youth, a high index of suspicion, and a firm desire to be a part of the solution are all that is required to address the problem of substance abuse in youth. In an age of "dotcoms" and societal complexity that fosters an emotionally "disconnected" atmosphere by uniting adolescents only by what they buy, plug into, click on, or blast away, teens need trusted medical homes where caring pediatricians are available to give youth accurate and authoritative facts and care to help them build inner resilience and connect them to the pain and hurt of the people in their lives. Until now, the "three strikes and you're out" maxim has been applied in medical care. This maxim may work for baseball, Clintonomics, and practical office management strategies but is not recommended for addressing the needs of substance using or abusing youth who are prey to advertising strategies. The size of the marketing and advertising budgets of the alcohol and cigarette industries is an indication of the relentless marketing directed toward vulnerable youth. Pediatricians would be doing teens a disservice if they fail to countermand this marketing effect by not using the "rule of seven"--the "seven 'S' screen," seven education attempts, seven different ways over 7 years, and persistence over seven attempts of chemically dependent adolescents to quit. It has been said by Osler that "These are our methods--to carefully observe the phenomena of life in all its stages, to cultivate the reasoning of the faculty so as to be able to know the true from the false. This is our work--to prevent disease, to relieve suffering, to heal the sick," and provide HOPE always.

  20. TWO-PARAMETER IRT MODEL APPLICATION TO ASSESS PROBABILISTIC CHARACTERISTICS OF PROHIBITED ITEMS DETECTION BY AVIATION SECURITY SCREENERS

    2017-01-01

    Full Text Available The modern approaches to the aviation security screeners’ efficiency have been analyzedand, certain drawbacks have been considered. The main drawback is the complexity of ICAO recommendations implementation concerning taking into account of shadow x-ray image complexity factors during preparation and evaluation of prohibited items detection efficiency by aviation security screeners. Х-ray image based factors are the specific properties of the x-ray image that in- fluence the ability to detect prohibited items by aviation security screeners. The most important complexity factors are: geometric characteristics of a prohibited item; view difficulty of prohibited items; superposition of prohibited items byother objects in the bag; bag content complexity; the color similarity of prohibited and usual items in the luggage.The one-dimensional two-parameter IRT model and the related criterion of aviation security screeners’ qualification have been suggested. Within the suggested model the probabilistic detection characteristics of aviation security screeners are considered as functions of such parameters as the difference between level of qualification and level of x-ray images com- plexity, and also between the aviation security screeners’ responsibility and structure of their professional knowledge. On the basis of the given model it is possible to consider two characteristic functions: first of all, characteristic function of qualifica- tion level which describes multi-complexity level of x-ray image interpretation competency of the aviation security screener; secondly, characteristic function of the x-ray image complexity which describes the range of x-ray image interpretation com- petency of the aviation security screeners having various training levels to interpret the x-ray image of a certain level of com- plexity. The suggested complex criterion to assess the level of the aviation security screener qualification allows to evaluate his or
