Anabolic androgenic steroids (AAS) are illicitly administered to enhance athletic performance and body image. Although conferring positive actions on performance, steroid abuse is associated with changes in anxiety and aggression. AAS users are often keenly invested in understanding the biological actions of these drugs. Thus, mechanistic information on AAS actions is important not only for the biomedical community, but also for steroid users. Here we review findings from animal studies on the impact of AAS exposure on neural systems that are crucial for the production of anxiety and aggression, and compare the effects of the different classes of AAS and their potential signaling mechanisms, as well as context-, age- and sex-dependent aspects of their actions.

Background This study examined associations between perceived neighborhood illicit drug selling, peer illicit drug disapproval and illicit drug use among a large nationally representative sample of U.S. high school seniors. Methods Data come from Monitoring the Future (2007–2011), an annual cross-sectional survey of U.S. high school seniors. Students reported neighborhood illicit drug selling, friend drug disapproval towards marijuana and cocaine use, and past 12-month and past 30-day illicit drug use (N = 10,050). Multinomial logistic regression models were fit to explain use of 1) just marijuana, 2) one illicit drug other than marijuana, and 3) more than one illicit drug other than marijuana, compared to “no use”. Results Report of neighborhood illicit drug selling was associated with lower friend disapproval of marijuana and cocaine; e.g., those who reported seeing neighborhood sales “almost every day” were less likely to report their friends strongly disapproved of marijuana (adjusted odds ratio [AOR] = 0.38, 95% CI: 0.29, 0.49) compared to those who reported never seeing neighborhood drug selling and reported no disapproval. Perception of neighborhood illicit drug selling was also associated with past-year drug use and past-month drug use; e.g., those who reported seeing neighborhood sales “almost every day” were more likely to report 30-day use of more than one illicit drug (AOR = 11.11, 95% CI: 7.47, 16.52) compared to those who reported never seeing neighborhood drug selling and reported no 30-day use of illicit drugs. Conclusions Perceived neighborhood drug selling was associated with lower peer disapproval and more illicit drug use among a population-based nationally representative sample of U.S. high school seniors. Policy interventions to reduce “open” (visible) neighborhood drug selling (e.g., problem-oriented policing and modifications to the physical environment such as installing and monitoring surveillance cameras) may

The use of social media (SM) as a surveillance tool of global illicit drug use is limited. To address this limitation, a systematic review of literature focused on the ability of SM to better recognize illicit drug use trends was addressed. A search was conducted in databases: PubMed, CINAHL via Ebsco, PsychINFO via Ebsco, Medline via Ebsco, ERIC, Cochrane Library, Science Direct, ABI/INFORM Complete and Communication and Mass Media Complete. Included studies were original research published in peer-reviewed journals between January 2005 and June 2015 that primarily focused on collecting data from SM platforms to track trends in illicit drug use. Excluded were studies focused on purchasing prescription drugs from illicit online pharmacies. Selected studies used a range of SM tools/applications, including message boards, Twitter and blog/forums/platform discussions. Limitations included relevance, a lack of standardized surveillance systems and a lack of efficient algorithms to isolate relevant items. Illicit drug use is a worldwide problem, and the rise of global social networking sites has led to the evolution of a readily accessible surveillance tool. Systematic approaches need to be developed to efficiently extract and analyze illicit drug content from social networks to supplement effective prevention programs. © The Author 2017.

Identification of pharmaceutical active ingredients sildenafil and tadalafil and the characterization of a dimethylated thio-derivative of sildenafil, called thioaildenafil or thiodimethylsildenafil, in illicit dietary supplements were described. A multi-residual ultra-performance liquid chromatography-time of flight mass spectrometry (UPLC-TOF/MS) method was developed to screen for the presence of the phosphodiesterase-5 (PDE-5) inhibitors sildenafil, tadalafil, and vardenafil and their analogues thioaildenafil and thiohomosildenafil in powders and pharmaceutical dosage forms. The study was developed in connection with an operation supervised by the Italian Medicines Agency (A.I.F.A.), aimed to monitor dietary supplements in the Italian market. In two of the eleven specimens under investigation, high-resolution mass spectrometry (HR-MS) allowed the identification of the PDE-5 inhibitors sildenafil and tadalafil, while another specimen proved to contain a unapproved dimethylated thioderivative of sildenafil, thioaildenafil or thiodimethylsildenafil, identified for the first time in Italy as adulterant in food supplements.

Regucalcin expression in bovine tissues and its regulation by sex steroid hormones in accessory sex glands.

Directory of Open Access Journals (Sweden)

Laura Starvaggi Cucuzza

Full Text Available Regucalcin (RGN is a mammalian Ca2+-binding protein that plays an important role in intracellular Ca2+ homeostasis. Recently, RGN has been identified as a target gene for sex steroid hormones in the prostate glands and testis of rats and humans, but no studies have focused on RGN expression in bovine tissues. Thus, in the present study, we examined RGN mRNA and protein expression in the different tissues and organs of veal calves and beef cattle. Moreover, we investigated whether RGN expression is controlled through sex steroid hormones in bovine target tissues, namely the bulbo-urethral and prostate glands and the testis. Sex steroid hormones are still illegally used in bovine husbandry to increase muscle mass. The screening of the regulation and function of anabolic sex steroids via modified gene expression levels in various tissues represents a new approach for the detection of illicit drug treatments. Herein, we used quantitative PCR, western blot and immunohistochemistry analyses to demonstrate RGN mRNA and protein expression in bovine tissues. In addition, estrogen administration down-regulated RGN gene expression in the accessory sex glands of veal calves and beef cattle, while androgen treatment reduced RGN gene expression only in the testis. The confirmation of the regulation of RGN gene expression through sex steroid hormones might facilitate the potential detection of hormone abuse in bovine husbandry. Particularly, the specific response in the testis suggests that this tissue is ideal for the detection of illicit androgen administration in veal calves and beef cattle.

Full Text Available Despite abounding evidence for the harmful effects of synthetic anabolic-androgenic steroids, they are commonly misused for competitive and body-image reasons. Steroids are often used in the context of poly-drug misuse, which may mask their specific effects on behaviour, such as increasing aggression. We present our case report as a concrete example of current steroid-related substance-misuse trends. A 25-year old Finnish male with various psychiatric and drug-related symptomology, but almost no previous history of aggressive behaviour, battered his wife to death and mutilated her body after a five-week steroid regimen.

on the basis of the Additional Protocol. This would allow the IAEA to allocate more resources for combating illicit trafficking. Concerning the basic requirements on combating illicit trafficking, it is observed that appropriate nuclear legislation has not been introduced in several countries. Some countries have the necessary legislation, but with a poor implementation and supervision of its adherence. With the purpose to effectively change this unsatisfactory situation, this study suggests, that a new international regime should be established by the Untied Nations and be assigned the task to: define the set of requirements and recommendations to be implemented in States for the effective combating of illicit trafficking, and to promote and pursue the implementation of and adherence to them; develop and establish a follow-up and audit system, with the purpose to review the implementation of those requirements and recommendations; carry out audits; when necessary, initiate the development of improved requirements, based on follow-up findings. Such a new Regime would not be intended to alter the current obligations of the IAEA as defined by its Statute and mandate. The role of the new organisation would be to supplement the obligations of the IAEA, as necessary, for the combating of illicit trafficking. It is important that the public and the media are getting full insight in the manner States are fulfilling their non-proliferation commitments. This study proposes that the principle of public access to information should apply regarding events related to illicit trafficking

Twenty-four products suspected of containing anabolic steroids and sold in fitness equipment shops in the United Kingdom (UK) were analyzed for their qualitative and semi-quantitative content using full scan gas chromatography-mass spectrometry (GC-MS), accurate mass liquid chromatography-mass spectrometry (LC-MS), high pressure liquid chromatography with diode array detection (HPLC-DAD), UV-Vis, and nuclear magnetic resonance (NMR) spectroscopy. In addition, X-ray crystallography enabled the identification of one of the compounds, where reference standard was not available. Of the 24 products tested, 23 contained steroids including known anabolic agents; 16 of these contained steroids that were different to those indicated on the packaging and one product contained no steroid at all. Overall, 13 different steroids were identified; 12 of these are controlled in the UK under the Misuse of Drugs Act 1971. Several of the products contained steroids that may be considered to have considerable pharmacological activity, based on their chemical structures and the amounts present. This could unwittingly expose users to a significant risk to their health, which is of particular concern for naïve users. Copyright © 2014 John Wiley & Sons, Ltd.

None of the trials reported on patient acceptability of the intervention.Two very different trials compared anabolic steroid versus control (no anabolic steroid or placebo). One trial compared anabolic steroid injections (given weekly until discharge from hospital or four weeks, whichever came first) versus placebo injections in 29 "frail elderly females". This found very low quality evidence of little difference between the two groups in the numbers discharged to a higher level of care or dead (one person in the control group died) (8/15 versus 10/14; risk ratio (RR) 0.75, 95% confidence interval (CI) 0.42 to 1.33; P = 0.32), time to independent mobilization or individual adverse events. The second trial compared anabolic steroid injections (every three weeks for six months) and daily protein supplementation versus daily protein supplementation alone in 40 "lean elderly women" who were followed up for one year after surgery. This trial provided very low quality evidence that anabolic steroid may result in less dependency, assessed in terms of being either dependent in at least two functions or dead (one person in the control group died) at six and 12 months, but the result was also compatible with no difference or an increase in dependency (dependent in at least two levels of function or dead at 12 months: 1/17 versus 5/19; RR 0.22, 95% CI 0.03 to 1.73; P = 0.15).

Mad men, women and steroid cocktails: a review of the impact of sex and other factors on anabolic androgenic steroids effects on affective behaviors.

For several decades, elite athletes and a growing number of recreational consumers have used anabolic androgenic steroids (AAS) as performance enhancing drugs. Despite mounting evidence that illicit use of these synthetic steroids has detrimental effects on affective states, information available on sex-specific actions of these drugs is lacking. The focus of this review is to assess information to date on the importance of sex and its interaction with other environmental factors on affective behaviors, with an emphasis on data derived from non-human studies. The PubMed database was searched for relevant studies in both sexes. Studies examining AAS use in females are limited, reflecting the lower prevalence of use in this sex. Data, however, indicate significant sex-specific differences in AAS effects on anxiety-like and aggressive behaviors, interactions with other drugs of abuse, and the interplay of AAS with other environmental factors such as diet and exercise. Current methods for assessing AAS use have limitations that suggest biases of both under- and over-reporting, which may be amplified for females who are poorly represented in self-report studies of human subjects and are rarely used in animal studies. Data from animal literature suggest that there are significant sex-specific differences in the impact of AAS on aggression, anxiety, and concomitant use of other abused substances. These results have relevance for human females who take these drugs as performance-enhancing substances and for transgender XX individuals who may illicitly self-administer AAS as they transition to a male gender identity.

Disneyization: A framework for understanding illicit drug use in bounded play spaces.

Science.gov (United States)

Turner, Tim

2018-05-17

This paper combines evidence from an ethnographic study of illicit drug use amongst tourists in Ibiza with Bryman's (2004) theoretical model of Disneyization. The principal aim was to construct a new conceptual framework that may help scholars, practitioners and policy makers make sense of dynamic patterns of illegal drug use across bounded play spaces such as tourist resorts, music festivals and nightclubs. Ethnographic fieldwork employing a grounded theory design was undertaken over three summers in tourist locations on the Balearic island of Ibiza, including nightclubs, bars, cafes, beaches, airports and hotels. Field notes from participant observation were supplemented with data from semi-structured interviews (n = 56) and secondary sources gathered from tourist marketing. The framework of Disneyization has been discussed in terms of 5 constructs: theming, hybrid consumption, branding, performative labour and atmospheres; each having a specific role in relation to understanding illicit drug use in bounded play spaces. Thus: Theming sets the stage, by physically and symbolically demarcating space with indelible themes of hedonism that open up the possibility of illicit drug use. Hybrid-consumption blurs the distinction between legal and illegal forms of intoxication, making the trading and consumption of illegal drugs appear like a natural feature of the consumer space. Branding demonstrates how participants construct intricate hierarchies of taste and credibility related to drug of choice. Performative labour re-enforces hybrid consumption, with participants working in the bounded play spaces of Ibiza immersed within the illicit drug market. Atmospheres represents the alchemic synergy of bounded play space and is important to understanding illicit drug use as a sensorial, deeply immersive but transitory experience. This research offers Disneyization as a new conceptual framework for making sense of deeply complex spatial, socio-cultural, psychological and

The prevalence of obesity and related morbidities such as nonalcoholic fatty liver disease (NAFLD) is high among adolescents. Current treatment recommendations for NAFLD focus on lifestyle optimization via nutrition and exercise. After encouraging exercise, many adolescents choose to participate in organized sports, which may lead to use of illicit substances such as anabolic androgenic steroids (AAS) to boost athletic performance. Approximately 3,000,000 individuals use non-therapeutic AAS at supra-physiologic doses in the United States.1 In 2012, 5.9% of adolescent boys reported steroid use in the previous year.2 We anticipate adolescents with pre-existing liver disease are at increased risk for AAS induced hepatotoxicity. We present such a case with IRB approval and written individual patient consent. PMID:23568051

The Buzz About Anabolic Androgenic Steroids: Electrophysiological Effects in Excitable Tissues

2012-01-01

Anabolic androgenic steroids (AAS) comprise a large and growing class of synthetic androgens used clinically to promote tissue-building in individuals suffering from genetic disorders, injuries and diseases. Despite these beneficial therapeutic applications, the predominant use of AAS is illicit: these steroids are self-administered to promote athletic performance and body image. Hand in hand with the desired anabolic actions of the AAS are untoward effects on the brain and behavior. While the signaling routes by which the AAS impose both beneficial and harmful actions may be quite diverse, key endpoints are likely to include ligand-gated and voltage-dependent ion channels that govern the activity of electrically excitable tissues. Here we review the known effects of AAS on molecular targets that play critical roles in controlling electrical activity, with a specific focus on the effects of AAS on neurotransmission mediated by GABAA receptors in the central nervous system (CNS).

Carbon isotope ratio (CIR) analysis of urinary steroids using gas chromatography-combustion isotope ratio mass spectrometry (GCC-IRMS) is a recognized test to detect illicit doping with synthetic testosterone. There are currently no universally used steroid isotopic standards (SIS). We adapted a protocol to prepare isotopically uniform steroids for use as a calibrant in GCC-IRMS that can be analyzed under the same conditions as used for steroids extracted from urine. Two separate SIS containing a mixture of steroids were created and coded CU/USADA 33-1 and CU/USADA 34-1, containing acetates and native steroids, respectively. CU/USADA 33-1 contains 5alpha-androstan-3beta-ol acetate (5alpha-A-AC), 5alpha-androstan-3alpha-ol-17-one acetate (androsterone acetate, A-AC), 5beta-androstan-3alpha-ol-11, 17-dione acetate (11-ketoetiocholanolone acetate, 11k-AC) and 5alpha-cholestane (Cne). CU/USADA 34-1 contains 5beta-androstan-3alpha-ol-17-one (etiocholanolone, E), 5alpha-androstan-3alpha-ol-17-one (androsterone, A), and 5beta-pregnane-3alpha, 20alpha-diol (5betaP). Each mixture was prepared and dispensed into a set of about 100 ampoules using a protocol carefully designed to minimize isotopic fractionation and contamination. A natural gas reference material, NIST RM 8559, traceable to the international standard Vienna PeeDee Belemnite (VPDB) was used to calibrate the SIS. Absolute delta(13)C(VPDB) and Deltadelta(13)C(VPDB) values from randomly selected ampoules from both SIS indicate uniformity of steroid isotopic composition within measurement reproducibility, SD(delta(13)C)<0.2 per thousand. This procedure for creation of isotopic steroid mixtures results in consistent standards with isotope ratios traceable to the relevant international reference material.

2014-01-01

Background The UK continues to experience a rise in the number of anabolic steroid-using clients attending harm reduction services such as needle and syringe programmes. Methods The present study uses interviews conducted with harm reduction service providers as well as illicit users of anabolic steroids from different areas of England and Wales to explore harm reduction for this group of drug users, focussing on needle distribution policies and harm reduction interventions developed specifically for this population of drug users. Results The article addresses the complexity of harm reduction service delivery, highlighting different models of needle distribution, such as peer-led distribution networks, as well as interventions available in steroid clinics, including liver function testing of anabolic steroid users. Aside from providing insights into the function of interventions available to steroid users, along with principles adopted by service providers, the study found significant tensions and dilemmas in policy implementation due to differing perspectives between service providers and service users relating to practices, risks and effective interventions. Conclusion The overarching finding of the study was the tremendous variability across harm reduction delivery sites in terms of available measures and mode of operation. Further research into the effectiveness of different policies directed towards people who use anabolic steroids is critical to the development of harm reduction. PMID:24986546

The objective of this study is to propose improvements of different means and methods for the prevention of illicit trafficking and the proliferation of nuclear weapons. An essential requirement imposed on authorities and operators through basic nuclear legislation is the establishment and implementation of: a) nuclear material accountancy and control; b) physical protection of nuclear material and facilities; and c) export/import control of nuclear material and, so called, dual-use items. The legislation would make it possible for the State nuclear authority to be informed continuously about the location and quantity of nuclear material in the country, and to monitor that it is under satisfactory protection and guard in accordance with the requirements. The introduction of requirements on licensing of practices and activities involving dual-use items, and other products used for nuclear weapons manufacturing, would also give the authority the possibility to prevent unauthorised transfers of such products. The nuclear legislation must clearly stipulate the distribution of responsibilities between nuclear authority, operator and employees. This would give a solid basis for attaining high safety culture, including positive motivation and active commitment among executives and other employees. It would also ensure that nuclear material would not be lost through negligence or internal criminal activities. A further step of improvements on the national level, would be the urgent and firm introduction of modern Quality Assurance and Internal Control Systems into all forms of nuclear activities. In modern, safety related quality control systems, the operator alone is responsible for all activities and operations, and he must establish an internal control that will ensure that the authority's rules and requirements are thoroughly implemented and adhered to. The operator's organisation, including competence and procedures, must be approved by the State authority. By means

From cigarette smuggling to illicit tobacco trade.

Tax policy is considered the most effective strategy to reduce tobacco consumption and prevalence. Tax avoidance and tax evasion therefore undermine the effectiveness of tax policies and result in less revenue for governments, cheaper prices for smokers and increased tobacco use. Tobacco smuggling and illicit tobacco trade have probably always existed, since tobacco's introduction as a valuable product from the New World, but the nature of the trade has changed. This article clarifies definitions, reviews the key issues related to illicit trade, describes the different ways taxes are circumvented and looks at the size of the problem, its changing nature and its causes. The difficulties of data collection and research are discussed. Finally, we look at the policy options to combat illicit trade and the negotiations for a WHO Framework Convention on Tobacco Control (FCTC) protocol on illicit tobacco trade. Twenty years ago the main type of illicit trade was large-scale cigarette smuggling of well known cigarette brands. A change occurred as some major international tobacco companies in Europe and the Americas reviewed their export practices due to tax regulations, investigations and lawsuits by the authorities. Other types of illicit trade emerged such as illegal manufacturing, including counterfeiting and the emergence of new cigarette brands, produced in a rather open manner at well known locations, which are only or mainly intended for the illegal market of another country. The global scope and multifaceted nature of the illicit tobacco trade requires a coordinated international response, so a strong protocol to the FCTC is essential. The illicit tobacco trade is a global problem which needs a global solution.

By 2016, tobacco industry provided the only illicit trade estimates in Colombia and used these to discourage tax increases since the 1990s. To establish the viability of a threefold hike in the excise tax, policy makers needed unbiased estimates of the illicit cigarette. To estimate the size of illicit cigarette trade in five Colombian cities (63% of the market), analyse characteristics of smokers of illicit cigarettes and compare market share results with one industry-funded survey. Street cross-sectional survey with smokers' self-report on consumption pattern, last purchase information and direct observation of smoker's packs. Sampling frame: smokers, men and women, 12 years old or older, all income levels, resident in five Colombian cities (Bogotá, Medellín, Cali, Cartagena and Cúcuta) with 1 733 316 smokers in 2013. Sample size 1697, simple random sample by city, sampling weights based on age groups and cities. Confidence level 95%, margin of error 3.5% for Bogotá and Medellín and 5% for the other three cities. Data collection period: 24 August-14 September 2016. Illicit cigarettes represent 3.5% of consumption in the five cities, a much lower estimate than the industry data. There are significant differences across cities, with Bogotá at the bottom (1.5%) and Cúcuta at the top (22.8%). The low overall penetration of illicit cigarettes in Colombia indicates that the industry's warnings against tax increases are not justified. The limited importance of tax levels as determinant of consumption of illicit cigarettes is also suggested by the differences across cities, all of them with the same tax regime. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Illicit cigarettes comprise more than 11% of tobacco consumption and 17% of consumption in low- and middle-income countries. Illicit cigarettes, defined as those that evade taxes, lower consumer prices, threaten national tobacco control efforts, and reduce excise tax collection. This paper measures the magnitude of illicit cigarette consumption within Indonesia using two methods: the discrepancies between legal cigarette sales and domestic consumption estimated from surveys, and discrepancies between imports recorded by Indonesia and exports recorded by trade partners. Smuggling plays a minor role in the availability of illicit cigarettes because Indonesians predominantly consume kreteks, which are primarily manufactured in Indonesia. Looking at the period from 1995 to 2013, illicit cigarettes first emerged in 2004. When no respondent under-reporting is assumed, illicit consumption makes up 17% of the domestic market in 2004, 9% in 2007, 11% in 2011, and 8% in 2013. Discrepancies in the trade data indicate that Indonesia was a recipient of smuggled cigarettes for each year between 1995 and 2012. The value of this illicit trade ranges from less than $1 million to nearly $50 million annually. Singapore, China, and Vietnam together accounted for nearly two-thirds of trade discrepancies over the period. Tax losses due to illicit consumption amount to between Rp 4.1 and 9.3 trillion rupiah, 4% to 13% of tobacco excise revenue, in 2011 and 2013. Due to the predominance of kretek consumption in Indonesia and Indonesia's status as the predominant producer of kreteks, illicit domestic production is likely the most important source for illicit cigarettes, and initiatives targeted to combat this illicit production carry the promise of the greatest potential impact.

To compare European students' personal use and approval of illicit substance use with their perceptions of peer behaviours and attitudes, and investigate whether perceptions of peer norms are associated with personal use of illicit substances and attitudes. This study used baseline data from the Social Norms Intervention for the prevention of Polydrug usE (SNIPE) project involving 4482 students from seven European countries in 2012. Students completed an online survey which included questions on personal and perceived peer illicit substance use and personal and perceived peer attitude towards illicit substances. 8.3% of students reported having used illicit substances at least once in their life. 49.7% of students perceived that the majority of their peers have used illicit substances more frequently than themselves. The perception was significantly associated with higher odds for personal illicit substance use (OR: 1.97, 95% CI: 1.53-2.54). The perception that the majority of peers approve illicit substance use was significantly associated with higher odds for personal approval of illicit substance use (OR: 3.47, 95% CI: 2.73-4.41). Students commonly perceived that their peers used illicit subtances more often than themselves. We found an association between the perceived peer norms/attitudes and reported individual behaviour/attitudes. Copyright © 2014 Elsevier Inc. All rights reserved.

The risk environment of anabolic-androgenic steroid users in the UK: Examining motivations, practices and accounts of use.

Hanley Santos, Gisella; Coomber, Ross

2017-02-01

The numbers using illicit anabolic-androgenic steroids are a cause of concern for those seeking to reduce health harms. Using the 'risk environment' as a conceptual framework to better comprehend how steroid users' practices and perspectives impact on health risks, this paper examines steroid user motivations, patterns of use, and the ways in which these practices are accounted for. As part of a wider mixed-method study into performance and image enhancing drug (PIED) use and supply in one mid-sized city in South West England, qualitative interviews were undertaken with 22 steroid users. Participants were recruited from a local safer injecting service, rather than bodybuilding gyms, in order to access a wider cross-section of steroid users. A limitation of this approach is potential sample bias towards those showing more health optimising behaviours. The research findings highlight that patterns of steroid use varied according to motivation for use, experience and knowledge gained. Most reported having had little or no knowledge on steroids prior to use, with first use being based on information gained from fellow users or suppliers-sometimes inaccurate or incomplete. In accounting for their practices, many users differentiated themselves from other groups of steroid users-for example, older users expressed concern over patterns of use of younger and (what they saw as) inexperienced steroid users. Implicit in these accounts were intimations that the 'other' group engaged in riskier behaviour than they did. Examining social contexts of use and user beliefs and motivations is vital to understanding how 'risk' behaviours are experienced so that this, in turn, informs harm reduction strategies. This paper examines the ways in which use of steroids is socially situated and the implications of this for policy and practice. Copyright © 2016 Elsevier B.V. All rights reserved.

Previous studies indicate that young people who have positive attitudes towards illicit drugs are more inclined to experiment with them. The first aim of our study was to identify the sociodemographic and risk behaviour characteristics of young people (16-24 years) with positive attitudes towards illicit drug use. The second aim was to identify the characteristics of young people with positive attitudes towards illicit drugs among those who had never tried drugs, those who had tried cannabis but no other illicit drugs, and those who regularly used cannabis and/or had tried other illicit drugs. The analysis was based on a population-based survey from 2013 ( N = 3812). Multiple logistic regression was used to analyse the association between sociodemographic and risk behaviour characteristics and positive attitudes towards illicit drugs. Young men had twice the odds of having positive attitudes towards illicit drug use compared with young women (AOR = 2.1). Also, young age, being single, being employed, smoking tobacco, practising unprotected sex, and experimental cannabis use were associated with positive attitudes towards illicit drug use. Finally, use of cannabis at least 10 times during the previous year and/or use of other illicit drugs had the strongest association with positive attitudes to illicit drug use (AOR = 6.0). Young people who have positive attitudes towards illicit drug use are characterized by a broad range of risky behaviours. These findings may help to identify young people at risk of initiating illicit drug use and thereby support the development and implementation of prevention programmes.

Illicit trafficking of nuclear materials continues to pose a danger to public health and safety and to nuclear non proliferation efforts. The majority of cases so far have involved only small amounts of fissile materials or mainly radioactive sources in Bulgaria. A proper scheme for analysis of seized nuclear materials will be developed based on existing equipment for NDA analysis of nuclear materials supplemented by new system through PHARE project assistance by EU experts.

Low protein diets supplemented with keto acid (sLPD) are recommended for patients with stage 3-5 chronic kidney disease (CKD). This study assessed whether sLPD is beneficial for patients with steroid-resistant proteinuria during early-stage CKD. A 1-year randomized controlled trial was conducted from 2010 to 2012. In this study, 108 proteinuric patients who were steroid-resistant were assigned to a sLPD group (0.6 g/kg/d with 0.09 g/kg/d keto acids) or a normal protein diet group (NPD, 1.0 g/kg/d). Estimated dietary protein intake, urinary protein excretion, remission rate, renal function, nutritional status, and blood pressure were measured. Baseline characteristics were comparable between the sLPD group (47 patients) and the NPD group (49 patients). Urinary protein excretion significantly decreased in sLPD compared to NPD in months 6, 9, and 12 (P<0.05). Proteinuria reduction was higher in sLPD than in NPD (P<0.001) at the end of the study. Complete remission and partial remission rates were higher in sLPD than in NPD. Serum albumin and pre-albumin levels were higher in sLPD than in NPD in months 9 and 12 (P<0.05). Serum total cholesterol and triglyceride levels declined more significantly in sLPD than in NPD (P<0.01) at the end of the study. There were no differences in nutritional status, renal function, hemoglobin, or blood pressure between the two groups. sLPD is both nutritionally safe and beneficial, providing nephroprotective effects for early-stage CKD patients with steroid-resistant proteinuria.

Undertreated pain is common among people who use illicit drugs (PWUD), and can often reflect the reluctance of health care providers to provide pain medication to individuals with substance use disorders. To investigate the relationship between having ever been denied pain medication by a health care provider and having ever reported using illicit drugs in hospital. Data were derived from participants enrolled in two Canadian prospective cohort studies between December 2012 and May 2013. Using bivariable and multivariable logistic regression analyses, the relationship between having ever been denied pain medication by a health care provider and having ever reported using illicit drugs in hospital was examined. Among 1053 PWUD who had experienced ≥ 1 hospitalization, 452 (44%) reported having ever used illicit drugs while in hospital and 491(48%) reported having ever been denied pain medication. In a multivariable model adjusted for confounders, having been denied pain medication was positively associated with having used illicit drugs in hospital (adjusted OR 1.46 [95% CI 1.14 to 1.88]). The results of the present study suggest that the denial of pain medication is associated with the use of illicit drugs while hospitalized. These findings raise questions about how to appropriately manage addiction and pain among PWUD and indicate the potential role that harm reduction programs may play in hospital settings.

Physical appearance concerns are uniquely associated with the severity of steroid dependence and depression in anabolic-androgenic steroid users.

Emerging research suggests that the sub-population of anabolic-androgenic steroid (AAS) users who experience physical appearance concerns may suffer greater psychological dysfunction than other sub-populations, including users with athletic or occupational concerns. Thus, among current AAS users, we sought to determine whether, and to what extent, social physique anxiety-an established measure of appearance concern-was associated with psychological dysfunction. Interviews were conducted with a sample of 74 male AAS users living in Australia. Users completed self-report instruments of the severity of AAS dependence, depression, hazardous and risky drinking, use of non-AAS illicit drugs, psychological side-effects due to AAS use and abnormal test results due to AAS use. Multivariate analyses revealed that greater social physique anxiety was uniquely associated with more severe symptoms of both AAS dependence and depression. Moreover, the effect size of these relationships was large. Social physique anxiety was not associated with hazardous or risky drinking, non-AAS illicit drug use, psychological side-effects or abnormal test results. Limitations notwithstanding, the study is consistent with the notion that AAS users who experience appearance concerns are at heightened risk of co-morbid psychological dysfunction. Given trends indicating an increase in the prevalence of AAS use in Australia and elsewhere, the findings suggest that health-care systems may need to consider prioritising the sub-population of AAS users who experience appearance concerns. Further investigation of the clinical syndrome of AAS dependence is required, including its relation to body image and eating disorders. © 2018 Australasian Professional Society on Alcohol and other Drugs.

2011-01-01

Background A review of the literature was conducted to examine the relationship between the use of anabolic androgenic steroid (AAS) use and the use of other drugs. Methods Studies published between the years of 1995–2010 were included in the review. Results The use of AAS is positively associated with use of alcohol, illicit drugs and legal performance enhancing substances. In contrast, the relationship between AAS and the use of tobacco and cannabis are mixed. Conclusion Results of the review indicate that the relationship between AAS use and other substance use depends on the type of substance studied. Implications for treatment and prevention are discussed. Suggestions for future research are provided. PMID:21232881

The Illicit nuclear trafficking panel was conducted at the 4th Annual INMM workshop on Reducing the Risk from Radioactive and Nuclear Materials on February 2-3, 2010 in Washington DC. While the workshop occurred prior to the Nuclear Security Summit, April 12-13 2010 in Washington DC, some of the summit issues were raised during the workshop. The Communique of the Washington Nuclear Security Summit stated that 'Nuclear terrorism is one of the most challenging threats to international security, and strong nuclear security measures are the most effective means to prevent terrorists, criminals, or other unauthorized actors from acquiring nuclear materials.' The Illicit Trafficking panel is one means to strengthen nuclear security and cooperation at bilateral, regional and multilateral levels. Such a panel promotes nuclear security culture through technology development, human resources development, education and training. It is a tool which stresses the importance of international cooperation and coordination of assistance to improve efforts to prevent and respond to incidents of illicit nuclear trafficking. Illicit trafficking panel included representatives from US government, an international organization (IAEA), private industry and a non-governmental organization to discuss illicit nuclear trafficking issues. The focus of discussions was on best practices and challenges for addressing illicit nuclear trafficking. Terrorism connection. Workshop discussions pointed out the identification of terrorist connections with several trafficking incidents. Several trafficking cases involved real buyers (as opposed to undercover law enforcement agents) and there have been reports identifying individuals associated with terrorist organizations as prospective plutonium buyers. Some specific groups have been identified that consistently search for materials to buy on the black market, but no criminal groups were identified that specialize in nuclear materials or isotope

2017-10-20

Drug overdoses are a leading cause of injury death in the United States, resulting in approximately 52,000 deaths in 2015. Understanding differences in illicit drug use, illicit drug use disorders, and overall drug overdose deaths in metropolitan and nonmetropolitan areas is important for informing public health programs, interventions, and policies. Illicit drug use and drug use disorders during 2003-2014, and drug overdose deaths during 1999-2015. The National Survey of Drug Use and Health (NSDUH) collects information through face-to-face household interviews about the use of illicit drugs, alcohol, and tobacco among the U.S. noninstitutionalized civilian population aged ≥12 years. Respondents include residents of households and noninstitutional group quarters (e.g., shelters, rooming houses, dormitories, migratory workers' camps, and halfway houses) and civilians living on military bases. NSDUH variables include sex, age, race/ethnicity, residence (metropolitan/nonmetropolitan), annual household income, self-reported drug use, and drug use disorders. National Vital Statistics System Mortality (NVSS-M) data for U.S. residents include information from death certificates filed in the 50 states and the District of Columbia. Cases were selected with an underlying cause of death based on the ICD-10 codes for drug overdoses (X40-X44, X60-X64, X85, and Y10-Y14). NVSS-M variables include decedent characteristics (sex, age, and race/ethnicity) and information on intent (unintentional, suicide, homicide, or undetermined), location of death (medical facility, in a home, or other [including nursing homes, hospices, unknown, and other locations]) and county of residence (metropolitan/nonmetropolitan). Metropolitan/nonmetropolitan status is assigned independently in each data system. NSDUH uses a three-category system: Core Based Statistical Area (CBSA) of ≥1 million persons; CBSA of illicit drugs, the prevalence was highest for the large metropolitan areas compared with

Liu Guifeng; Ma Shihua; Ji Te; Zhao Hongwei; Wang Wenfeng

2010-01-01

The tera hertz time-domain spectroscopy (THz-TDS) was used for sensing and identifying illicit drugs. The absorption spectra of seven illicit drug samples(morphine and its hydrochloride, cocaine hydrochloride, codeine phosphate, papaverine hydrochloride, pethidine hydrochloride, and thebaine) were studied by THz-TDS at 0.3-2.0 THz at room temperature. The geometric structure and vibration frequencies of morphine were calculated by density functional theory. The four absorption features were dominated by intra-/inter-molecular collective or lattice vibration modes. Each illicit drug has a distinct signature in its THz spectra. The results indicate that the THz-TDS can be used to identify and discriminate illicit drugs by their characteristic fingerprints. (authors)

Drug interactions between common illicit drugs and prescription therapies.

Lindsey, Wesley T; Stewart, David; Childress, Darrell

2012-07-01

The aim was to summarize the clinical literature on interactions between common illicit drugs and prescription therapies. Medline, Iowa Drug Information Service, International Pharmaceutical Abstracts, EBSCO Academic Search Premier, and Google Scholar were searched from date of origin of database to March 2011. Search terms were cocaine, marijuana, cannabis, methamphetamine, amphetamine, ecstasy, N-methyl-3,4-methylenedioxymethamphetamine, methylenedioxymethamphetamine, heroin, gamma-hydroxybutyrate, sodium oxybate, and combined with interactions, drug interactions, and drug-drug interactions. This review focuses on established clinical evidence. All applicable full-text English language articles and abstracts found were evaluated and included in the review as appropriate. The interactions of illicit drugs with prescription therapies have the ability to potentiate or attenuate the effects of both the illicit agent and/or the prescription therapeutic agent, which can lead to toxic effects or a reduction in the prescription agent's therapeutic activity. Most texts and databases focus on theoretical or probable interactions due to the kinetic properties of the drugs and do not fully explore the pharmacodynamic and clinical implications of these interactions. Clinical trials with coadministration of illicit drugs and prescription drugs are discussed along with case reports that demonstrate a potential interaction between agents. The illicit drugs discussed are cocaine, marijuana, amphetamines, methylenedioxymethamphetamine, heroin, and sodium oxybate. Although the use of illicit drugs is widespread, there are little experimental or clinical data regarding the effects of these agents on common prescription therapies. Potential drug interactions between illicit drugs and prescription drugs are described and evaluated on the Drug Interaction Probability Scale by Horn and Hansten.

Steroidal Saponins

Science.gov (United States)

Sahu, N. P.; Banerjee, S.; Mondal, N. B.; Mandal, D.

The medicinal activities of plants are generally due to the secondary metabolites (1) which often occur as glycosides of steroids, terpenoids, phenols etc. Saponins are a group of naturally occurring plant glycosides, characterized by their strong foam-forming properties in aqueous solution. The cardiac glycosides also possess this, property but are classified separately because of their specific biological activity. Unlike the cardiac glycosides, saponins generally do not affect the heart. These are classified as steroid or triterpenoid saponins depending on the nature of the aglycone. Steroidal glycosides are naturally occurring sugar conjugates of C27 steroidal compounds. The aglycone of a steroid saponin is usually a spirostanol or a furostanol. The glycone parts of these compounds are mostly oligosaccharides, arranged either in a linear or branched fashion, attached to hydroxyl groups through an acetal linkage (2, 3). Another class of saponins, the basic steroid saponins, contain nitrogen analogues of steroid sapogenins as aglycones.

Antiobesity drugs have been marketed illicitly by "no prescription" online pharmacies after approval and scheduling by the drug enforcement agency. We assess whether antiobesity drug Belviq® (lorcaserin HCl) was available from illicit online vendors before DEA-scheduling when sales are unauthorized. Online searches of "buy Belviq no prescription" examining first five result pages marketing the drug. Searches were performed from 11/5/2012-12/8/2012, prior to DEA scheduing. Belviq® is actively marketed by "no prescription" online vendors despite official unavailability and prescription requirements. Approaches included direct-to-consumer advertising using descriptive website URLs; linking to illicit marketers; and directing customers to other weight-loss websites for additional marketing. Finally, large quantities were marketed by business-to-business vendors. Illicit online "no prescription" pharmacies are marketing unauthorized, suspect antiobesity drugs before DEA scheduling and permitted marketing. Regulators must legally intercede to ensure patient safety, and providers must educate patients about online-sourcing risks. Copyright © 2013 The Obesity Society.

Patients receiving steroids or having disease processes which increase natural steroid production often demonstrate ''the classic x-ray changes'' of avascular necrosis of bone. Bone scintigraphy in these patients most frequently demonstrates an increased radionuclide localization. The literature suggests that the increased activity is related to healing of the avascular process. In a recent study of Legg-Calve-Perthes Disease (LCPD), 37 of the children had multiple studies and increased activity within the epiphysis during revascularization was extremely rare. Not only are the scintigraphic findings in steroid osteopathy dissimilar to that in healing LCPD, but the time interval for healing is much to short for that of a vascular necrosis and no patients demonstrated an avascular phase on bone scintigraphy. Of 15 children with renal transplants on steroid therapy, 9 demonstrated x-ray and clinical findings of osteopathy. In 8 of 9 instances, bone scintigraphy showed increased localization of radionuclide in the affected bone. Improvement or a return to normal occurred in those patients in whom steroids were discontinued. The following is a proposed mechanism for steroid osteopathy. Steroids affect the osteoblastic and osteoclastic activity of bone and weaken its internal structure. Ordinary stress produces microtrabecular fractures. Fractures characteristically stimulate reactive hyperemia and increase bone metabolism. The result is increased bone radiopharmaceutical localization. The importance of recognizing this concept is that steroid osteopathy is preventable by reducing the administered steroid dose. As opposed to avascular necrosis, bone changes are reversible.

Youth at risk of illicit drug abuse and other delinquent acts are the target of social work services. Preventing or discouraging the use of illicit drugs among at-risk youth is a long-standing practical and research concern. For this reason, the preventive function of courage is a research gap the present study seeks to fill. The study collected data from 169 at-risk youths and their social workers with two-wave panel surveys. Results show that courage in Wave 1 presented a strong negative effect on illicit drug use in Wave 2 in the youth, controlling for illicit drug use in Wave 1 and background characteristics. Moreover, the negative effect was stronger when Wave 1 drug use was more likely. These results imply the helpfulness of encouraging at-risk youth to gather courage to resist the temptation to use illicit drugs. © The Author(s) 2014.

Illicit drugs policy through the lens of regulation.

Science.gov (United States)

Ritter, Alison

2010-07-01

The application of regulatory theory to the problem of illicit drugs has generally been thought about only in terms of 'command and control'. The international treaties governing global illicit drug control and the use of law enforcement to dissuade and punish offenders have been primary strategies. In this paper I explore the application of other aspects of regulatory theory to illicit drugs-primarily self-regulation and market regulation. There has been an overreliance on strategies from the top of the regulatory pyramid. Two other regulatory strategies--self-regulation and market regulation--can be applied to illicit drugs. Self-regulation, driven by the proactive support of consumer groups may reduce drug-related harms. Market strategies such as pill-testing can change consumer preferences and encourage alternate seller behaviour. Regulatory theory is also concerned with partnerships between the state and third parties: strategies in these areas include partnerships between police and pharmacies regarding sale of potential precursor chemicals. Regulatory theory and practice is a rich and well-developed field in the social sciences. I argue that governments should consider the full array of regulatory strategies. Using regulatory theory provides a rationale and justification to strategies that are currently at the whim of politics, such as funding for user groups. The greater application of regulatory approaches may produce more flexible and structured illicit drug policies. Copyright (c) 2009 Elsevier B.V. All rights reserved.

Metabolism of anabolic steroids and their relevance to drug detection in horseracing.

Science.gov (United States)

Teale, Philip; Houghton, Edward

2010-06-01

The fight against doping in sport using analytical chemistry is a mature area with a history of approximately 100 years in horseracing. In common with human sport, anabolic/androgenic steroids (AASs) are an important group of potential doping agents. Particular issues with their detection are extensive metabolism including both phase I and phase II. A number of the common AASs are also endogenous to the equine. A further issue is the large number of synthetic steroids produced as pharmaceutical products or as 'designer' drugs intended to avoid detection or for the human supplement market. An understanding of the metabolism of AASs is vital to the development of effective detection methods for equine sport. The aim of this paper is to review current knowledge of the metabolism of appropriate steroids, the current approaches to their detection in equine sport and future trends that may affect equine dope testing.

Full Text Available Illicit drugs use is a real public health issue, especially among young people. The totality of the drugs harmful effects on the body is difficult to quantify, especially because of poor epidemiological data and ethical concerns about the inclusion of consumers in clinical trials. However, health professionals need to be alert to identify, report and fight drug-related pathology. This article aims to draw attention to the lung pathology induced by the consumption of some of the most commonly used illicit drugs: cocaine, heroin and cannabis.

Cell-free expression has become a highly promising tool for the efficient production of membrane proteins. In this study, we used a dialysis-based Escherichia coli cell-free system for the production of a membrane protein actively integrated into liposomes. The membrane protein was the light-driven proton pump bacteriorhodopsin, consisting of seven transmembrane alpha-helices. The cell-free expression system in the dialysis mode was supplemented with a combination of a detergent and a natural lipid, phosphatidylcholine from egg yolk, in only the reaction mixture. By examining a variety of detergents, we found that the combination of a steroid detergent (digitonin, cholate, or CHAPS) and egg phosphatidylcholine yielded a large amount (0.3-0.7 mg/mL reaction mixture) of the fully functional bacteriorhodopsin. We also analyzed the process of functional expression in our system. The synthesized polypeptide was well protected from aggregation by the detergent-lipid mixed micelles and/or lipid disks, and was integrated into liposomes upon detergent removal by dialysis. This approach might be useful for the high yield production of functional membrane proteins.

Illicit cigarette consumption has increased worldwide. It is important to understand this problem thoroughly. To investigate behaviours and factors associated with illicit cigarette consumption in southern Thailand. A survey and qualitative study were conducted in a border province in southern Thailand next to Malaysia. A modified snowballing technique was used to recruit 300 illicit and 150 non-illicit cigarette smokers. A questionnaire was used to interview subjects. Illicit cigarette packs were obtained in order to identify their characteristics. Bivariate and multivariate logistic regression was used for data analysis. Smoking of illicit cigarettes has become accepted in the communities. They were available in supermarkets and vendor shops. Friends and other illicit smokers known by illicit cigarette smokers were an important source of information for access to illicit cigarette products. The main factors associated with smoking illicit cigarettes, compared with smoking non-illicit cigarettes, were younger age, higher education and higher average monthly expenditure on cigarettes (most illicit smokers smoked illicit cigarettes (average price per packet = 33 THB (US$1.1), while most non-illicit smokers smoked hand-rolled cigarettes (average price per packet = 7 THB (US$0.2)) and knowledge of other illicit cigarette smokers. The low price of illicit cigarettes was the main reason for their use. Selling strategies included sale of singles, sale in shops and direct sale through social networking. Illicit cigarette consumption has become more acceptable especially among young adult smokers. Age and extent of social networks are important factors associated with smoking illicit cigarettes.

Trauma activation patients: evidence for routine alcohol and illicit drug screening.

C Michael Dunham

Full Text Available BACKGROUND: Statistics from the National Trauma Data Bank imply that discretionary blood alcohol and urine drug testing is common. However, there is little evidence to determine which patients are appropriate for routine testing, based on information available at trauma center arrival. In 2002, Langdorf reported alcohol and illicit drug rates in Trauma Activation Patients. METHODOLOGY/PRINCIPAL FINDINGS: This is a retrospective investigation of alcohol and illicit drug rates in consecutive St. Elizabeth Health Center (SEHC trauma patients. SEHC Trauma Activation Patients are compared with the Langdorf Activation Patients and with the SEHC Trauma Nonactivation Patients. Minimum Rates are positive tests divided by total patients (tested and not tested. Activation patients: The minimum alcohol rates were: SEHC 23.1%, Langdorf 28.2%, combined 24.8%. The minimum illicit drug rates were: SEHC 15.7%, Langdorf 23.5, combined 18.3%. The minimum alcohol and/or illicit drug rates were: SEHC 33.4%, Langdorf 41.8%, combined 36.2%. Nonactivation patients: The SEHC minimum alcohol rate was 4.7% and the minimum illicit drug rate was 6.0%. CONCLUSIONS: Alcohol and illicit drug rates were significantly greater for Trauma Activation Patients, when compared to Nonactivation Patients. At minimum, Trauma Activation Patients are likely to have a 1-in-3 positive test for alcohol and/or an illicit drug. This substantial rate suggests that Trauma Activation Patients, a readily discernible group at trauma center arrival, are appropriate for routine alcohol and illicit drug testing. However, discretionary testing is more reasonable for Trauma Nonactivation Patients, because minimum rates are low.

The effects of long-term (over several years) anabolic androgen steroids (AAS) administration on human skeletal muscle are still unclear. In this study, seventeen strength training athletes were recruited and individually interviewed regarding self-administration of banned substances. Ten subjects admitted having taken AAS or AAS derivatives for the past 5 to 15 years (Doped) and the dosage and type of banned substances were recorded. The remaining seven subjects testified to having never used any banned substances (Clean). For all subjects, maximal muscle strength and body composition were tested, and biopsies from the vastus lateralis muscle were obtained. Using histochemistry and immunohistochemistry (IHC), muscle biopsies were evaluated for morphology including fiber type composition, fiber size, capillary variables and myonuclei. Compared with the Clean athletes, the Doped athletes had significantly higher lean leg mass, capillary per fibre and myonuclei per fiber. In contrast, the Doped athletes had significantly lower absolute value in maximal squat force and relative values in maximal squat force (relative to lean body mass, to lean leg mass and to muscle fiber area). Using multivariate statistics, an orthogonal projection of latent structure discriminant analysis (OPLS-DA) model was established, in which the maximal squat force relative to muscle mass and the maximal squat force relative to fiber area, together with capillary density and nuclei density were the most important variables for separating Doped from the Clean athletes (regression  =  0.93 and prediction  =  0.92, p<0.0001). In Doped athletes, AAS dose-dependent increases were observed in lean body mass, muscle fiber area, capillary density and myonuclei density. In conclusion, long term AAS supplementation led to increases in lean leg mass, muscle fiber size and a parallel improvement in muscle strength, and all were dose-dependent. Administration of AAS may induce sustained

The global diversion of pharmaceutical drugs. India: the third largest illicit opium producer?

Science.gov (United States)

Paoli, Letizia; Greenfield, Victoria A; Charles, Molly; Reuter, Peter

2009-03-01

This paper explores India's role in the world illicit opiate market, particularly its role as a producer. India, a major illicit opiate consumer, is also the sole licensed exporter of raw opium: this unique status may be enabling substantial diversion to the illicit market. Participant observation and interviews were carried out at eight different sites. Information was also drawn from all standard secondary sources and the analysis of about 180 drug-related criminal proceedings reviewed by Indian High Courts and the Supreme Court from 1985 to 2001. Diversion from licit opium production takes place on such a large scale that India may be the third largest illicit opium producer after Afghanistan and Burma. With the possible exceptions of 2005 and 2006, 200-300 tons of India's opium may be diverted yearly. After estimating India's opiate consumption on the basis of UN-reported prevalence estimates, we find that diversion from licit production might have satisfied a quarter to more than a third of India's illicit opiate demand to 2004. India is not only among the world's largest consumer of illicit opiates but also one of the largest illicit opium producers. In contrast to all other illicit producers, India owes the latter distinction not to blatantly illicit cultivation but to diversion from licit cultivation. India's experience suggests the difficulty of preventing substantial leakage, even in a relatively well-governed nation.

The Internet is a popular tool for marketing and purchasing herbal dietary supplements (DS). Various Web sites sell these products purely for recreational use. To describe the content of Web sites that advertise and market herbal DS for recreational use (ie, for the purpose of altering mood/behavior/or perception, "getting high," or as a substitute for a drug of abuse). Four major search engines and the search terms "buy herbal high" and "buy legal high" were used to identify Web sites selling herbal DS for recreational use. Web sites were evaluated for their country of origin and for compliance with the Dietary Supplement Health and Education Act (DSHEA). Products were evaluated for their ingredient lists, effect claims, comparisons with illicit drugs, adverse effects, drug interactions, and contraindications. Twenty-eight unique Web sites with 119 products were evaluated. Most sites were in the US (54%) and were in compliance with DSHEA. Forty-seven percent of the products were likened to illicit drugs, typically marijuana (48%) or 3-,4-methylene dioxyamphetamine (Ecstasy; 23%). The most common product ingredients were ephedra alkaloids (27%), Salvia divinorum (17%), kava (10%), guarana (10%), Acorus calamus (10%), and damiana (10%). Effect claims frequently involved the products' use as a hallucinogen (51%) or stimulant (39%). Sixty-four percent of the sites mentioned adverse effects, and 54% mentioned drug interactions. This study demonstrates that herbal DS are being marketed for use as legal alternatives to illicit drugs of abuse. Healthcare professionals need to be aware of this trend and the products that are involved.

Anabolic steroids are widely used to increase skeletal muscle (SM) mass and improve physical performance. Some dietary supplements also include potent steroid precursors or active steroid analogs such as nandrolone. Our previous study reported the anabolic steroid effects on SM in a castrated guinea pig model with SM measured using a highly quantitative magnetic resonance imaging (MRI) protocol. The aim of the current study was to apply this animal model and in vivo MRI protocol to evaluate the growth effects of four widely used over-the-counter testosterone and nandrolone precursors: 4-androstene-3 17-dione (androstenedione), 4-androstene-3β 17β-diol (4-androsdiol), 19-nor-4-androstene-3β-17β-diol (bolandiol) and 19-nor-4-androstene-3 17-dione (19-norandrostenedione). The results showed that providing precursor to castrated male guinea pigs led to plasma steroid levels sufficient to maintain normal SM growth. The anabolic growth effects of these specific precursors on individual and total muscle volumes, sexual organs, and total adipose tissue over a 10-week treatment period, in comparison with those in the respective positive control testosterone and nandrolone groups, were documented quantitatively by MRI.

THE EFFECT OF ILLICIT TRADE IN NARCOTICS ON GLOBAL ECONOMY

ALASMARI Khaled

Illicit markets especially those dealing with narcotics constitute grievous issues to the world’s economies, putting to test global safety, economic progress as well as security and many other aspects. Seemingly, illicit narcotics trade in the last decade – that is 2000 to 2011 underwent a significant boom, resulting from a wide spectrum of illegal drugs such as cocaine as well as heroin among many other hard drugs. In today’s global society, several concerns are emerging on the rise of illicit narcotics trade accompanied with organized crime, chiefly as major hindrances to consistent global economic progress. Apparently, some of the effects of illicit narcotics trade are that; this trade gradually turns upside down business rules, opening way for new unruly market players besides reconfiguring influence in global economics as well as politics. Surprisingly, the revenue from illegal drugs in 2011 alone was roughly 10% of the global GDP. Hence, exaggerating local economies’ incomes and triggering ceaseless conflicts among market players, while at the same time reducing legal business activities likewise disintegrating socioeconomic conditions. An empirical research method was adopted for this study, analyzing illicit trade in narcotics on the global arena as from 2000 to 2011 and its resultant effects. The research findings indicate that, illegal drugs trade particularly on the world economy besides growing at a high rate, it endangers the overall welfare of humans likewise the business environment. This is ostensibly because this trade has high chances of engrossing regional economies into illegal drugs business activities, causing them to neglect sustainable ethical businesses. Now, to effectively address negative economic issues related to illegal drugs trade, there is apparent need for integrated efforts from local as well as international authorities. Such efforts are chiefly to control not only the harmful effects resulting from the use of illicit

A strategy to reduce illicit drug use is effective in elite Australian football.

The World Anti-Doping Agency (WADA) prescribes that drug testing is conducted in sports competitions to detect drug use in athletes. This testing includes performance-enhancing drugs as well as illicit substances such as marijuana, amphetamines and cocaine. Illicit drugs are tested for on match days but not on non-match days. Some athletes are known to use illicit substances for recreational purposes, away from competition times and this poses a serious health and welfare issue not addressed by the usual sport drug testing regimes. This paper reports the results of the first 7 years of an illicit drug-testing programme that included non-match day testing in the elite Australian Football competition, the Australian Football League (AFL). Players in the AFL were tested for illicit drugs both in-competition and out-of-competition. Players were selected for illicit substance tests either randomly or targeted based on previous test history or time since previous test. The number of tests conducted was increased each year from 2005 to 2011 and testing was focused on high-risk times during non-competition periods. There were no positive match day tests. There was a significant reduction in positive tests (19-6) for illicit drugs during non-competition periods over the 7 years (p<0.0001). The reduction in positive tests may be related to player education, the greater number of tests conducted and the harm minimisation approach of the illicit drug policy. An illicit drugs programme using a harm minimisation strategy can work effectively alongside a sport's WADA compliant Anti-Doping Code.

The use of counterfeit or substandard medicines can have an important health impact, resulting in therapeutic failure, be toxic or even cause death. Anabolic steroids are a frequent target for counterfeiters worldwide, being the second most frequent counterfeited class in Brazil. The aims of this work were to optimize and validate a GC-MS method for the quantitative determination of anabolic steroids in tablet, aqueous suspension and oil solution forms, and to analyze pharmaceutical products sent to Brazilian Federal Police (BFP) for forensic analysis. Sample preparation included extraction with methanol in ultrasonic bath followed by centrifugation. The method was successfully validated and 345 samples of pharmaceutical products were analyzed (328 medicines and 17 dietary supplements). About 42% of the medicines were counterfeits, 28.7% of tablets, 12.0% of suspensions and 65.2% of oil solutions; 11% were considered substandards. Five dietary supplements contained undeclared anabolic steroids, including two containing methandrostenolone at 5.4 and 5.8mg/capsule, equivalent to levels found in medicines. The proposed method is suitable for implementation in routine analysis for identification of counterfeits and substandard products. The analytical results show the need to raise awareness of consumers over the risks from the consumption of anabolic steroids from the clandestine market and for more incisive actions from government agencies aiming at decreasing the availability of these products.

Multi-level governance: The way forward for European illicit drug policy?

Science.gov (United States)

Chatwin, Caroline

2007-12-01

Illicit drug policy has long been an area that has attracted international policy intervention, however, the European Union has declared it an area of subsidiarity, leaving ultimate control to national governments. Nevertheless, European Union preoccupation with the illicit drug issue and international drug trafficking and organised crime concerns have ensured that continued and increased cooperation in illicit drug policy is never off the agenda. This article examines the history of European integration in contrasting areas of policy and considers both the desirability and the viability of an increasingly harmonised drug policy for Europe. Finally, it proposes a model of integrated illicit drug policy that is strongly connected to developing patterns of European social policy, calling on multi-level governance and close involvement at the level of the citizen.

Illicit drugs and their metabolites are the latest group of emerging pollutants. Determination of their concentration in environment (such as water bodies, soil, sediment, air) is an indirect tool to estimate the community level consumption of illicit drug and to evaluate potential ecotoxicological impacts from chronic low level exposure. They enter the wastewater network as unaltered drugs and/or their active metabolites by human excretion after illegal consumption or by accidental or deliberate disposal from clandestine drug laboratories. This article critically reviews the occurrence and concentration levels of illicit drugs and their metabolites in different environmental compartments (e.g., wastewater, surface waters, groundwater, drinking water, and ambient air) and their potential impact on the ecosystem. There is limited published information available on the presence of illicit drugs in the environment, reports are available mainly from European countries, UK, USA, and Canada but there is a lack of information from the remainder of the world. Although the environmental concentrations are not very high, they can potentially impact the human health and ecosystem functioning. Cocaine, morphine, amphetamine, and MDMA have potent pharmacological activities and their presence as complex mixtures in water may cause adverse effect on aquatic organisms and human health. However, there is no current regulation demanding the determination of occurrence of these emerging pollutants in treated wastewater, surface water, drinking water, or atmosphere. Thus, critical investigation on distribution pattern of this new group of emerging contaminant and their potential harmful impact on our environment needs immediate attention. Copyright © 2012.

Full Text Available The consequences of inflammatory response are primarily responsible for morbimortality in bacterial meningitis. Early use of steroids in these cases can reduce mortality and hearing loss and improve functional outcome without causing significant side effects. The formal recommendation towards pneumoccocal meningitis is being extended to other forms of Bacterial Meningitis. The same thought can be applied to tuberculous meningitis. In neurocysticercosis and neuroschistosomiasis steroids are more useful than parasiticides in most cases. Despite the evidence favoring the use of steroids in herpes simplex encephalitis, it is not sufficient to definitely support such indication. Among the opportunistic infections that affect AIDS patients, neurotoxoplasmosis and progressive multifocal leukoencephalopaty are those most often considered for the use of steroids; steroids are safe to use, but no definite benefit could be demonstrated in both conditions.

In traditional method we need fingerprints of all the pure chemical components. In practical as only the objective components in a mixture and their absorption features are known, it is necessary and important to present a more practical technique for the detection and identification. Our new method of quantitatively inspect of the mixtures of illicit drugs is developed by using derivative spectrum. In this method, the ratio of objective components in a mixture can be obtained on the assumption that all objective components in the mixture and their absorption features are known but the unknown components are not needed. Then methamphetamine and flour, a illicit drug and a common adulterant, were selected for our experiment. The experimental result verified the effectiveness of the method, which suggested that it could be an effective method for quantitative identification of illicit drugs. This THz spectroscopy technique is great significant in the real-world applications of illicit drugs quantitative analysis. It could be an effective method in the field of security and pharmaceuticals inspection.

Background It is not yet known if the increased risk of suicide in substance abusers is caused by the causal and/or coexisting relationship between substance use and psychiatric disorders. This study was designed to estimate the suicide risk among individuals with illicit drug use alone, illicit drug users with mental disorders, and illicit drug users with alcohol use disorders. Methods Subjects were participants of the 2008 Thai National Mental Health Survey. They were asked for their illicit drug use in the past year. The Mini International Neuropsychiatric Interview (MINI), current suicidality (1 month prior to assessment), mood episodes, anxiety disorders, psychotic disorders, and alcohol use disorders were used for assessing mental/alcohol use disorders. A score of 1 or more for the MINI–Suicidality module was defined as the presence of suicide risk. Results Of the total 17,140 respondents, 537 currently used illicit drugs, while 1,194 respondents had a suicide risk. Common illicit drugs were kratom (59%) and (meth)amphetamine (24%). Compared with 16,603 Thais without illicit drug use, the illicit drug users with or without mental/alcohol use disorders (n=537) had an increased risk of suicide (adjusted odds ratio [OR], 95% confidence interval [CI] =2.09, 1.55–2.81). While those who used illicit drugs alone (no mental/alcohol use disorder) (n=348) had no increased risk of suicide (adjusted OR, 95% CI =1.04, 0.66–1.65), the illicit drug users with mental or alcohol use disorders (n=27 and n=162, respectively) had significantly increased risk of suicide (adjusted ORs, 95% CIs =14.06, 6.50–30.3 and 3.14, 1.98–4.99, respectively). Conclusion A key limitation of this study was the combined suicidal behaviors as a suicidality risk. Mental or alcohol use disorders found in this population actually increased the suicide risk. These findings support the coexisting relationship that mental and alcohol use disorders play a vital role in increasing the suicide

Illicit Financial Flows and their Developmental Impacts: An Overview

Full Text Available Illicit financial flows — cross-border capital movements for the purposes of concealing illegal activities and evading taxes — pose major challenges to developing countries. They deprive the country concerned of urgently needed resources for private and public investment, thereby hampering infrastructure building and economic growth. This research overview shows that illicit financial flows also favour political changes that go hand in hand with the weakening of state institutions and growing corruption and rent-seeking. As yet, there are no empirical quantitative findings as to the exact functioning and significance of these effects. What is clear, however, is that approaches to problem-solving must come not only from the countries where illicit financial flows originate but also from the recipient countries — offshore financial centres with a high level of financial secrecy.

Social causation and neighborhood selection underlie associations of neighborhood factors with illicit drug-using social networks and illicit drug use among adults relocated from public housing.

Theories of social causation and social influence, which posit that neighborhood and social network characteristics are distal causes of substance use, are frequently used to interpret associations among neighborhood characteristics, social network characteristics and substance use. These associations are also hypothesized to result from selection processes, in which substance use determines where people live and who they interact with. The potential for these competing selection mechanisms to co-occur has been underexplored among adults. This study utilizes path analysis to determine the paths that relate census tract characteristics (e.g., economic deprivation), social network characteristics (i.e., having ≥ 1 illicit drug-using network member) and illicit drug use, among 172 African American adults relocated from public housing in Atlanta, Georgia and followed from 2009 to 2014 (7 waves). Individual and network-level characteristics were captured using surveys. Census tract characteristics were created using administrative data. Waves 1 (pre-relocation), 2 (1st wave post-relocation), and 7 were analyzed. When controlling for individual-level sociodemographic factors, residing in census tracts with prior economic disadvantage was significantly associated with illicit drug use at wave 1; illicit drug use at wave 1 was significantly associated with living in economically-disadvantaged census tracts at wave 2; and violent crime at wave 2 was associated with illicit drug-using social network members at wave 7. Findings from this study support theories that describe social causation and neighborhood selection processes as explaining relationships of neighborhood characteristics with illicit drug use and illicit drug-using social networks. Policies that improve local economic and social conditions of neighborhoods may discourage substance use. Future studies should further identify the barriers that prevent substance users from obtaining housing in less

Our objective was to evaluate local guidelines regarding early steroid treatment in adult community acquired bacterial meningitis, and assess the actual treatment given and its correlation to clinical outcome. Patient outcome was obtained retrospectively from the medical records of 210 adults...... admitted to 47 hospitals in Denmark during 2002-2004 (population 5.4 million) and was combined with results from a questionnaire regarding treatment guidelines in these hospitals. In 36 of 47 departments responding to the questionnaire, 21 recommended early steroid treatment, but none did so initially...... during 2002. Early steroid treatment was given to 15% of patients and was given more often when recommended locally (41% vs 11%, OR=5.7 (2.4-13.5)). Unfavourable outcome was demonstrated rarely in patients treated with early steroids compared to the non-steroid group (17% vs 42%, p

Background The World Anti-Doping Agency (WADA) prescribes that drug testing is conducted in sports competitions to detect drug use in athletes. This testing includes performance-enhancing drugs as well as illicit substances such as marijuana, amphetamines and cocaine. Illicit drugs are tested for on match days but not on non-match days. Some athletes are known to use illicit substances for recreational purposes, away from competition times and this poses a serious health and welfare issue not addressed by the usual sport drug testing regimes. This paper reports the results of the first 7 years of an illicit drug-testing programme that included non-match day testing in the elite Australian Football competition, the Australian Football League (AFL). Methods Players in the AFL were tested for illicit drugs both in-competition and out-of-competition. Players were selected for illicit substance tests either randomly or targeted based on previous test history or time since previous test. The number of tests conducted was increased each year from 2005 to 2011 and testing was focused on high-risk times during non-competition periods. Results There were no positive match day tests. There was a significant reduction in positive tests (19–6) for illicit drugs during non-competition periods over the 7 years (psport's WADA compliant Anti-Doping Code. PMID:22893512

Thailand borders some of the world's largest methamphetamine and opioid producing countries and trafficking routes. Thailand's 'War on Drugs' campaign was launched in 2003. This study reports trends in illicit substance use in Thailand over the period 2001-2011. National Household surveys on illicit drug use were conducted in 2001, 2003, 2007, 2008 and 2011. A stratified multi-stage cluster random sampling technique was implemented for each survey. Provinces in four regions were systematically selected using a probability proportionate to the size of the targeted population. Participants were interviewed using structured questionnaires on their history of substance use. The prevalence of illicit drug use within the past drastically decreased from 4.5% in 2001 to 1.0% in 2003 (P survey. Other types of illicit drugs were less commonly used in Thailand. There was a decrease in prevalence of illicit drug use within the past year between 2001 and 2003 in Thailand. Since 2003, the past year prelavence of illicit drug use has remained relatively stable. From 2001 to 2011, cannabis, kratom and yaba have remained the three most commonly reported types of illicit drugs used in Thailand. © 2018 Australasian Professional Society on Alcohol and other Drugs.

Full Text Available Political unstability, less respect to the role of law, low life standards and suitable conditions for poppy/coca cultivation, have all affected on growing illicit drug international trafficking. Colombia is the center for global cocaine industry. Colombians had to use ship in the Carribean but now they pass Mexico where the costs are half of using ship. Mexican traffickers permit that the domestic poppy plants turned into herion, Colombian cocaine transited to USA and methamephtamine manufactured and distributed. Golden triangle in southeast Asia is one of the major regions for opium poppy cultivation. This region has seen many guerrilla warfare for selling illicit drugs especially in Myanmar. Manufactured hroin is usually dealt in Thailand. Golden Crescent region in southwest Asia has a suitable climate for opium poppy cultivation which provides necessay money for purchasing needed weapons by rival groups in northwestern border provinces of Afghanistan and Pakistan. Nigeria is one of the main centers for transporting heroin from Golden Crescent and cocaine from Brazil. Dominics run cocaine trade in New York and New England and Afro-American criminal organizations conduct heroin trading in big cities such as New york, Detroit, Chicago, Phila Delphia and Washington. Street trading of illicit drugs is mainly done by cultural or commanding gangs. Illicit drug traffickers apply many methods to laundering their profits including money exchange, smurfs, electronic transferring, and faced firms (the firms that are only registered.

Some Experience with Illicit Trafficking of Radioactive Materials in Tanzania

International Nuclear Information System (INIS)

Ngaile, J.E.; Banzi, F.P.; Kifanga, L.D.

2008-01-01

Illicit trafficking of radioactive materials (orphan sources or disuse sources) is of global concern. Reports on the IAEA Illicit Trafficking Data Base (ITDB) indicates increasing trend of incidents recorded in more than 40 countries on six continents[1]. It is suspected that nuclear trafficking is fueled by nuclear terrorism and is a threat for increasing illegal trade in nuclear and radioactive materials to manufacture Radiological Disposal Devices (RDD)- dirty bombs. As such, the international co-operative efforts are needed to uncover and combat nuclear trafficking in order to minimize its consequences such as external radiation exposure of persons from source to various radiation levels during illicit movement and after seizure; rupture of source leading to internal exposure of persons and environmental contamination. Although accidents with radioactive materials have not occurred in the United Republic of Tanzania (URT), incidents of illicit trafficking and unauthorized possession of radioactive materials has occurred thus prompting the Tanzania Atomic Energy Commission (TAEC) to strengthen its nuclear security of nuclear and radioactive material in the URT. Nuclear faclities and radioactive sources lacks adequate physical protection against theft, fire or different forms of unauthorized access. Tanzaniaia has recorded about thirteen (13) illicit trafficking incidents of radioactive between 1996-2006. Caesium-137, Uranium-238; and Uranium oxide standard and Radium-226 with activity ranging from low to significantly high were among the radiounuclides which were intercepted. Most of these incidents had their original outside Tanzania. The incidents were uncovered by informers in cooperation with the police. Despite the fact that the management of these incidents by the police were adequate, it was observed that there is an inadequate radiation protection arrangements during transport of seized sources; lack of precautions for safety when handling seized

Full Text Available Abstract Background Despite growing concern about illicit methadone use in the US and other countries, there is little data about the prevalence and correlates of methadone use in large urban areas. We assessed the prevalence and examined correlates of lifetime and recent illicit methadone use in New York City (NYC. Methods 1,415 heroin, crack, and cocaine users aged 15–40 years were recruited in NYC between 2000 and 2004 to complete interviewer-administered questionnaires. Results In multivariable logistic regression, non-injection drug users who used illicit methadone were more likely to be heroin dependent, less than daily methamphetamine users and to have a heroin using sex partner in the last two months. Injection drug users who used illicit methadone were more likely to use heroin daily, share injection paraphernalia and less likely to have been in a detoxification program and to have not used marijuana in the last six months. Conclusion The results overall suggest that illicit (or street methadone use is likely not a primary drug of choice, but is instead more common in concert with other illicit drug use.

Little evidence, other than that commissioned by the tobacco industry, exists on the size of the illicit tobacco trade. This study addresses this gap by examining the level and nature of illicit cigarettes and hand-rolled tobacco in 18 European countries. Face-to-face cross-sectional survey on smoking. 18 European countries. For each country, around 1000 subjects representative of the population aged 15 and over were enrolled. Current cigarette smokers were asked to show their latest purchased pack of cigarettes or hand-rolled tobacco. A comprehensive measure called an Identification of an Illicit Pack (IIP) was used to study the extent of illicit trade, defining a pack as illicit if it had at least one of the following tax evasion indicators: (1) it was bought from illicit sources, as reported by smokers, (2) it had an inappropriate tax stamp, (3) it had an inappropriate health warning or (4) its price was substantially below the known price in their market. Overall, the proportion of illicit packs was 6.5%. The highest prevalence of IIP was observed in Latvia (37.8%). Illicit packs were more frequent among less educated smokers and among those living in a country which shared a land or sea border with Ukraine, Russia, Moldova or Belarus. No significant association was found with price of cigarettes. This study indicates that IIP is less than 7% in Europe and suggests that the supply of illicit tobacco, rather than its price, is a key factor contributing to tax evasion.

The empirical analysis of cigarette tax avoidance and illicit trade in Vietnam, 1998-2010.

Full Text Available Illicit trade carries the potential to magnify existing tobacco-related health care costs through increased availability of untaxed and inexpensive cigarettes. What is known with respect to the magnitude of illicit trade for Vietnam is produced primarily by the industry, and methodologies are typically opaque. Independent assessment of the illicit cigarette trade in Vietnam is vital to tobacco control policy. This paper measures the magnitude of illicit cigarette trade for Vietnam between 1998 and 2010 using two methods, discrepancies between legitimate domestic cigarette sales and domestic tobacco consumption estimated from surveys, and trade discrepancies as recorded by Vietnam and trade partners. The results indicate that Vietnam likely experienced net smuggling in during the period studied. With the inclusion of adjustments for survey respondent under-reporting, inward illicit trade likely occurred in three of the four years for which surveys were available. Discrepancies in trade records indicate that the value of smuggled cigarettes into Vietnam ranges from $100 million to $300 million between 2000 and 2010 and that these cigarettes primarily originate in Singapore, Hong Kong, Macao, Malaysia, and Australia. Notable differences in trends over time exist between the two methods, but by comparison, the industry estimates consistently place the magnitude of illicit trade at the upper bounds of what this study shows. The unavailability of annual, survey-based estimates of consumption may obscure the true, annual trend over time. Second, as surveys changed over time, estimates relying on them may be inconsistent with one another. Finally, these two methods measure different components of illicit trade, specifically consumption of illicit cigarettes regardless of origin and smuggling of cigarettes into a particular market. However, absent a gold standard, comparisons of different approaches to illicit trade measurement serve efforts to refine

The efficacy of oral steroid therapy for autoimmune pancreatitis (AIP) is well known, and oral prednisolone treatment is most usually commenced at 30-40 mg/day, but there have been few reports about comparative studies of oral steroid therapy and steroid pulse therapy as the initial treatment for AIP. We studied the clinical course and image findings to estimate the utility of steroid pulse therapy for AIP, comparing it with oral steroid therapy. Laboratory and image findings were assessed retrospectively in 11 patients who received steroid pulse therapy, and the findings were compared to those in 10 patients who received conventional oral steroid therapy. Change in pancreatic size showed no significant difference between the therapies after 2 weeks of treatment. Significant improvement of lower bile duct strictures after 2 weeks of treatment and that of immunoglobulin values within 6 months were shown with both therapies. However, steroid pulse therapy showed significant improvement of γ-guanosine triphosphate (GTP) in 2 weeks and of alanine aminotransferase (ALT) in 2 and 8 weeks, compared with oral steroid therapy. Moreover, there was one patient in whom the lower bile duct stricture was not improved by oral steroid therapy, but it did show improvement with steroid pulse therapy. Initial steroid pulse therapy is a beneficial alternative to oral steroid therapy for the improvement of bile duct lesions. In future, the accumulation of a larger number of patients receiving steroid pulse therapy is needed, and prospective studies will be required. (author)

To determine if illicit drug use increases the vertical transmission of HIV, to identify the risk factors involved in mother and child health and the prevalence of illicit drug use among these pregnant women. Sixty-four (7.6%) of 845 pregnant women from the metropolitan region of Belo Horizonte, Minas Gerais, Brazil, attended in the service between October 1997 and February 2012 reported the use of illicit drugs. Cases were HIV-positive drug users (n=64) and controls were women who did not use drugs (n=192). Three controls were selected for each case. Several conditions of exposure were considered in the control group such as tobacco use, alcohol use, alcohol and tobacco use, maternal age, educational level, ethnicity, and marital status. Problems during the prenatal period, delivery and postpartum, vertical HIV transmission and neonatal outcomes were also investigated. Univariate analysis showed as significant variables: maternal age, tobacco use, number of prenatal care visits, antiretroviral therapy, mode of infection, and viral load at delivery. Logistic regression revealed as significant variables: maternal age (less than 25 years); tobacco use, and number of prenatal care visits (less than 6). The vertical transmission of HIV was 4,8% (95%CI 1.7-13.3) among drug users and 2,1% (95%CI 0.8-5.2) in the control group, with no statistically significant difference between groups. Neonatal complications were more frequent among drug users, but also with no statistically significant difference between groups. The use of illicit drug is frequent during pregnancy among HIV-infected women. The approach to illicit drug use should be routine during prenatal care visits. These women are more discriminated against and tend to deny their habits or do not seek prenatal care. There was no difference in vertical virus transmission between groups, probably indicating adherence to antiretroviral use for antiretroviral therapies during pregnancy.

Tobacco tax and the illicit trade in tobacco products in New Zealand.

To estimate the size of illegal tobacco trade and consumption and assess the impact of tobacco tax on the illicit tobacco market in New Zealand (NZ). Data on the import and seizure of legal and illegal tobacco in NZ was obtained from NZ Customs. Previous literature was used to calculate interception rates of illegal tobacco being smuggled and grown in NZ. Annual tobacco returns figures, obtained via the NZ Ministry of Health, were analysed to assess the market dynamics of legal tobacco products. This study found that illicit tobacco constituted 1.8-3.9% of total national tobacco consumption in NZ in 2013. This represents a minor increase compared to previous estimates from 2007-09, suggesting that tax increases enacted by the NZ Government since 2010 have had a minimal impact on encouraging the use and procurement of illicit tobacco. The results highlight a slight rise in small-scale tobacco smuggling through ports and mail centres. However, tobacco returns figures show that current tobacco tax policy has forced manufacturers to focus on the production of cheap legal tobacco products, directly competing with and undercutting the demand for illicit tobacco products. At the same time, locally grown illicit tobacco continues to remain a small, isolated problem and, with recent cuts in duty free tobacco allowance, it is expected that overall illicit tobacco will remain a very small proportion of total tobacco consumption in NZ. © 2015 Public Health Association of Australia.

Doping control is a main priority for regulatory bodies of both the horse racing industry and the equestrian sports. Urine and blood samples are screened for the presence of hundreds of forbidden substances including anabolic-androgenic steroids (AASs). Based on the suspected endogenous origin of some AASs, with β-boldenone as the most illicit candidate, this study aimed to improve the knowledge of the naturally present AAS in horse urine. To this extent, a novel ultra high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method was developed and validated according to the Association of Official Racing Chemists (AORC) and European Commission (EC) guidelines, proving the power of this new method. Low limits of detection (0.2 ng/mL), good reproducibility (percentage of standard deviation (%RSD)  0.99 and lack-of-fit analysis) were obtained for all included AASs. With this method, urine samples of 105 guaranteed untreated horses (47 geldings, 53 mares, and 5 stallions serving as a control) were screened for β-boldenone and five related natural steroids: androstadienedione (ADD), androstenedione (AED), alpha-testosterone (αT), beta-testosterone (βT), and progesterone (P). Progesterone, β-testosterone, and α-testosterone were detected in more than half of the horses at low concentrations (anabolic-androgenic steroids naturally present in urine of untreated horses (mares and geldings).

Impaired neurodevelopment in preterm infants is caused by prematurity itself; however, hypoxia/ischemia, inflammation, and hyperoxia contribute to the extent of impairment. Because preterm birth is accompanied by a dramatic decrease in 17β-estradiol (E2) and progesterone, preliminary clinical studies have been carried out to substitute these steroids in preterm infants; however, they failed to confirm significantly improved neurologic outcomes. We therefore hypothesized that the persistently high postnatal production of fetal zone steroids [mainly dehydroepiandrosterone (DHEA)] until term could interfere with E2-mediated protection. We investigated whether E2 could reduce hyperoxia-mediated apoptosis in three immature glial cell types and detected the involved receptors. Thereafter, we investigated protection by the fetal zone steroids DHEA, 16α-hydroxy-DHEA, and androstenediol. For DHEA, the involved receptors were evaluated. We examined aromatases, which convert fetal zone steroids into more estrogenic compounds. Finally, cotreatment was compared against single hormone treatment to investigate synergism. In all cell types, E2 and fetal zone steroids resulted in significant dose-dependent protection, whereas the mediating receptors differed. The neuroprotection by fetal zone steroids highly depended on the cell type-specific expression of aromatases, the receptor repertoire, and the potency of the fetal zone steroids toward these receptors. No synergism in fetal zone steroid and E2 cotreatment was detected in two of three cell types. Therefore, E2 supplementation may not be beneficial with respect to neuroprotection because fetal zone steroids circulate in persistently high concentrations until term in preterm infants. Hence, a refined experimental model for preterm infants is required to investigate potential treatments. Copyright © 2017 Endocrine Society.

Strategies to reduce illicit uses of radioactive materials. The Ethiopian perspective

Full text: The illicit uses of radioactive sources can impose a direct danger to public health and safety. A number of cases worldwide have resulted in ionizing radiation exposures to individuals. Although the incident of illicit trafficking is greatly influenced by the national system of protection of radioactive materials at their use and storage location this alone may not ensure an absolute guarantee against such occurrence. The challenges of preventing illicit uses of radioactive sources and activities are more complex in the face of more integrated global economic environment. The national system of control, the cross border involvement, multiplicity of participants in the supply to end-use chain, diversity of systems and instruments are factors contributing to this complexity. Smooth interplay and overall systemic effectiveness of the national system of regulatory control, the strategic coordination of responsible parties and the systemic tie of such bodies, the efficiency of information flow and the pattern of know-how and training is what ensure the effectiveness of preventing, detecting and responding to any illicit activities and trafficking of radioactive sources. In Ethiopia, the attempts/incidents of illegal use were so far limited. However, the possibility of such occurrence cannot be ruled out and due attention should be paid as the activity is complex and is a global problem of general concern. Therefore, in addressing these issues the following strategies are believed appropriate in Ethiopia's perspective for preventing and controlling illicit uses and trafficking of radioactive materials: Strengthening the national system of control and protection including boarder controlling; Achieving effective coordination within and among regulators, law enforcement bodies and customs; Developing and maintaining effective system of information handling and flow; Training of principally responsible parties in the prevention, detection and response to illicit

Since the early nineties, illicit trafficking (IT) of nuclear materials and radioactive sources appeared as a new trend which raised the concern of the international community due to the grave consequences that would merge if these materials or radioactive sources fell into the hands of terrorist groups. However, by the end of the last century illicit trafficking of nuclear materials and radioactive sources lost its considerable salience, in spite of seizure of considerable amounts of 2 '3'5U (76% enrichment) in Bulgaria (May 1999) and also 235 U (30% enrichment) in Georgia (April 2000). Nevertheless, IT should be always considered as a continued and viable threat to the international community. Awareness of the problem should be developed and maintained among concerned circles as the first step towards combating illicit trafficking of nuclear materials and radioactive sources. Illicit trafficking of nuclear and radioactive materials needs serious consideration and proper attention by the governmental law enforcement authorities. Measures to combat with IT of nuclear material or radioactive sources should be effective in recovery, of stolen, removed or lost nuclear materials or radioactive sources due to the failure of the physical protection system or the State System Accounting and Control (SSAC) system which are normally applied for protecting these materials against illegal actions. Measures such as use of modern and efficient radiation monitoring equipment at the borders inspection points, is an important step in preventing the illicit trafficking of nuclear and radioactive materials across the borders. Also providing radiological training to specific personnel and workers in this field will minimize the consequences of a radiological attack in case of its occurrence. There is a real need to start to enter into cooperative agreements to strengthen borders security under the umbrella of IAEA to faster as an international cooperation in the illicit trafficking

To ensure fair competition and to protect the horse's welfare, horses have to compete on their own merits, without any unfair advantage that might follow the use of drugs. Therefore, regulatory authorities list all substances that are not allowed in competition, including most anabolic-androgenic steroids. As zero-tolerance is retained, the question arose whether the consumption of mouldy feed could lead to the excretion of steroids, due to the biotransformation of plant phytosterols to steroids. A rapid ultra high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) analytical method, previously validated according to AORC (Association of Official Racing Chemists) and EC (European Commission) guidelines, was used to measure steroids in different sample types. Multiple mouldy feed samples were tested for the presence of steroids. The effect of digestion was tested by in vitro simulation of the horse's hindgut in batch incubations. In most feed samples no steroids were detected, even when the products were mouldy. Mouldy corn however showed to contain up to 3.0 ± 0.4 µg/kg AED (4-androstenedione), the main testosterone precursor. This concentration increased when mouldy corn (with added phytosterols) was digested in vitro. An herbal phytosupplement also showed to contain α-testosterone. These results demonstrate that it is important to caution against the consumption of any feed or (herbal) supplement of which the detailed ingredients and quantitative analysis are unknown. The consumption of mouldy corn should especially be avoided, not only from a horse health and welfare point of view, but also to avoid possible inadvertent positive doping results.

2001-01-01

The known use of performance enhancing agents by athletes has occurred throughout history. In the 1960s and 1970s steroids and amphetamines were the supplements most often used. Now athletes are turning to supplements that are either natural or stimulate the release of natural hormones. The purpose of this study is to evaluate the prevalence of use of nutritional supplements among high school football and volleyball players. This study surveyed 495 male football players and 407 female volleyball players from 20 high schools in Northwest Iowa. These athletes completed anonymous surveys and returned them to their coaches. Results showed that 8% of the male athletes and 2% of the female athletes were using supplementation. Supplements used included creatine, androstiendione, HMB, amino acids, DHEA, phosphogen, weight gainer 1850, Tribulus, muscle plus, multivitamins, calcium, GABA, and Shaklee Vita Lea and Physique.

Sex steroids are essential for reproduction and development in animals and humans, and sex steroids also play an important role in neuroprotection following brain injury. New data indicate that sex-specific responses to brain injury occur at the cellular and molecular levels. This review summarizes the current understanding of neuroprotection by sex steroids, particularly estrogen, androgen, and progesterone, based on both in vitro and in vivo studies. Better understanding of the role of sex steroids under physiological and pathological conditions will help us to develop novel effective therapeutic strategies for brain injury. PMID:20595940

In recent years, the Thai government has strengthened drug law enforcement as a strategy to address a continuing epidemic of illicit drug use. We sought to assess temporal trends in street-level availability of illicit drugs among injection drug users (IDUs) in Bangkok, Thailand. Using univariate statistics and multivariate logistic regression, we assessed changes in the availability of five substances (heroin, methamphetamine, crystal methamphetamine, midazolam, and illicit methadone) between 2009 and 2011 and examined social, structural and individual factors influencing availability among community-recruited samples of IDUs in Bangkok. Availability was measured in three levels: immediate (available in ≤10 min); moderate (available in 10-90 min); and delayed (available in >90 min; our reference category). The analyses included 718 IDUs, including 165 (23.0%) women. Controlling for changes in participant characteristics between assessments, and in a period of constant nominal illicit drug prices, moderate availability of all substances increased significantly between 2009 and 2011, with adjusted odds ratios ranging between 2.36 (illicit methadone) and 4.61 (crystal methamphetamine) (all pdrug suppression efforts, the availability of illicit drugs among IDUs in Bangkok increased significantly between 2009 and 2011. The findings raise concern about the overreliance on drug law enforcement-based approaches and point to the need for greater investment in evidence-based drug policies.

ABSTRACT OBJECTIVE To estimate factors associated to illicit drug use among patients with mental illness in Brazil according to gender. METHODS A cross-sectional representative sample of psychiatric patients (2,475 individuals) was randomly selected from 11 hospitals and 15 public mental health outpatient clinics. Data on self-reported illicit drug use and sociodemographic, clinical and behavioral characteristics were obtained from face-to-face interviews. Logistic regression was used to estimate associations with recent illicit drug use. RESULTS The prevalence of any recent illicit drug use was 11.4%. Men had higher prevalence than women for all substances (17.5% and 5.6%, respectively). Lower education, history of physical violence, and history of homelessness were associated with drug use among men only; not professing a religion was associated with drug use in women only. For both men and women, younger age, current hospitalization, alcohol and tobacco use, history of incarceration, younger age at sexual debut, and more than one sexual partner were statistically associated with illicit drug use. CONCLUSIONS Recent illicit drug use among psychiatric patients is higher than among the general Brazilian population and it is associated with multiple factors including markers of psychiatric severity. Our data indicate the need for the development of gender-based drug-use interventions among psychiatric patients in Brazil. Integration of substance use treatment strategies with mental health treatment should be a priority. PMID:28832753

Purpose To determine the in vivo effects of several particulate steroids on microvascular perfusion by using intravital microscopy in a mice model and to investigate the in vitro interactions between these particulate steroids and red blood cells (RBCs). Materials and Methods The study was conducted in agreement with the guidelines of the National Committee of Ethic Reflection on Animal Experimentation. By using intravital microscopy of mouse cremaster muscle, the in vivo effects of several particulate steroids on microvascular perfusion were assessed. Four to five mice were allocated to each of the following treatment groups: saline solution, dexamethasone sodium phosphate, a nonparticulate steroid, and the particulate steroids cortivazol, methylprednisolone, triamcinolone, and prednisolone. By using in vitro blood microcinematography and electron microscopy, the interactions between these steroids and human RBCs were studied. All results were analyzed by using nonparametric tests. Results With prednisolone, methylprednisolone, or triamcinolone, blood flow was rapidly and completely stopped in all the arterioles and venules (median RBC velocity in first-order arterioles, 5 minutes after administration was zero for these three groups) compared with a limited effect in mice treated with saline, dexamethasone, and cortivazol (20.3, 21.3, and 27.5 mm/sec, respectively; P effect was associated with a large decrease in the functional capillary density (4.21, 0, and 0 capillaries per millimeter for methylprednisolone, triamcinolone, or prednisolone, respectively, vs 21.0, 21.4, and 19.1 capillaries per millimeter in mice treated with saline, dexamethasone, and cortivazol, respectively; P steroids. Conclusion Several particulate steroids have an immediate and massive effect on microvascular perfusion because of formation of RBC aggregates associated with the transformation of RBCs into spiculated RBCs.

2017-12-01

Limited information is present in literature regarding detection of illicit drug users visiting physicians when planning elective surgery; also, there is no update manuscript that is illustrating the effects of illicit drugs use that require reconstructive surgery interventions. Aims of this manuscript are: 1) to summarize existing knowledge, and give surgeons information how to detect patients who might possible use illicit drugs; 2) to review the effects of illicit drug use that specifically require reconstructive surgery interventions; 3) to assess on existing policies on asymptomatic illicit drug users when planning elective surgery. Studies were identified by searching systematically in the electronic databases PubMed, Medline, The Cochrane Library and SveMed+. Because of the nature of research questions to be investigated (drug policy and surgery), a "systematic review" was not possible. In spite of some existing policies to detect illicit drug use in specific situations such as workplaces or acute trauma patients, there is a lack of data and lack of information, and subsequently no policy has ever been made, for detection and management of illicit drug use asymptomatic patients requesting or referred for plastic surgery interventions. This manuscript poses questions for further ethical evaluations and future policy. Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd. All rights reserved.

3,4-Methylenedioxymethamphetamine (MDMA) is the major ingredient of ecstasy illicit pills. It is a hallucinogen, central nervous system stimulant, and serotonergic neurotoxin that strongly releases serotonin from serotonergic nerves terminals. Moreover, it releases norepinephrine and dopamine from nerves terminal, but to a lesser extent than serotonin. Poisoning and even death from abusing MDMA-containing ecstasy illicit pills among abusers is usual. Thus, quantitative determination of MDMA content of ecstasy illicit pills in illicit drug bazaar must be done regularly to find the most high dose ecstasy illicit pills and removing them from illicit drug bazaar. In the present study, MDMA contents of 13 most abundant ecstasy illicit pills were determined by quantitative thin-layer chromatography (TLC). Two procedures for quantitative determination of MDMA contents of ecstasy illicit pills by TLC were used: densitometric and so-called 'scraping off' methods. The former was done in a reflection mode at 285 nm and the latter was done by absorbance measurement of eluted scraped off spots. Limit of detection (LOD), considering signal-to-noise ratio (S/N) of 2, and limit of quantification (LOQ), regarding S/N of 10, of densitometric and scraping off methods were 0.40 microg, 1.20 microg, and 6.87 mug, 20.63 microg, respectively. Repeatabilities (within-laboratory error) of densitometric and scraping off methods were 0.5% and 3.6%, respectively. The results showed that the ecstasy illicit pills contained 24-124.5 mg and 23.9-122.2 mg MDMA by densitometric and scraping off methods, respectively.

The suggestion has been made that neurological changes seen in the syndrome of chronic traumatic encephalopathy may be due to exogenous anabolic steroid use rather than traumatic brain injury. To determine whether administration of anabolic steroids alters the pathophysiology of traumatic brain injury. Sixty adult male Sprague-Dawley rats and a linear acceleration model of traumatic brain injury were used. Experimental groups were (1) preinjury anabolic steroids, (2) preinjury placebo carrier, (3) anabolic steroids without injury, (4) no steroids and no injury, (5) postinjury placebo carrier, and (6) postinjury anabolic steroids. Following a 30-day recovery, rats were euthanized, and brainstem white matter tracts underwent fluorescent immunohistochemical processing and labeling of β-amyloid precursor protein (APP), a marker of axonal injury. Digital imaging and statistical analyses were used to determine whether anabolic steroid administration resulted in a significant change in the number of injured axons. There was no statistically significant difference in number of APP-positive axons by immunohistochemical analysis between respective anabolic steroid and placebo groups. Using a standard acceleration-deceleration model of mild traumatic brain injury, we have shown successful visualization of traumatically injured axons with antibody staining of APP. Our results indicate no statistically significant effect of anabolic steroids on the number of APP-positive axons. With the use of this model, and within its limitations, we see no adverse effect or causative role of anabolic steroid administration on the brain following mild traumatic brain injury using APP counts as a marker for anatomic injury.

A review of ecological effects and environmental fate of illicit drugs in aquatic ecosystems.

Although illicit drugs are detected in surface waters throughout the world, their environmental fate and ecological effects are not well understood. Many illicit drugs and their breakdown products have been detected in surface waters and temporal and spatial variability in use translates into "hot spots and hot moments" of occurrence. Illicit drug occurrence in regions of production and use and areas with insufficient wastewater treatment are not well studied and should be targeted for further study. Evidence suggests that illicit drugs may not be persistent, as their half-lives are relatively short, but may exhibit "pseudo-persistence" wherein continual use results in persistent occurrence. We reviewed the literature on the ecological effects of these compounds on aquatic organisms and although research is limited, a wide array of aquatic organisms, including bacteria, algae, invertebrates, and fishes, have receptors that make them potentially sensitive to these compounds. In summary, illicit drugs occur in surface waters and aquatic organisms may be affected by these compounds; research is needed that focuses on concentrations of illicit drugs in areas of production and high use, environmental fate of these compounds, and effects of these compounds on aquatic ecosystems at the concentrations that typically occur in the environment.

Sex steroids and neurogenesis.

Science.gov (United States)

Heberden, Christine

2017-10-01

The brain has long been known as a dimorphic organ and as a target of sex steroids. It is also a site for their synthesis. Sex steroids in numerous ways can modify cerebral physiology, and along with many processes adult neurogenesis is also modulated by sex steroids. This review will focus on the effects of the main steroids, estrogens, androgens and progestogens, and unveil some aspects of their partly disclosed mechanisms of actions. Gonadal steroids act on different steps of neurogenesis: cell proliferation seems to be increased by estrogens only, while androgens and progestogens favor neuronal renewal by increasing cell survival; differentiation is a common target. Aging is characterized by a cognitive deficiency, paralleled by a decrease in the rate of neuronal renewal and in the levels of circulating gonadal hormones. Therefore, the effects of gonadal hormones on the aging brain are important to consider. The review will also be expanded to related molecules which are agonists to the nuclear receptors. Sex steroids can modify adult neuronal renewal and the extensive knowledge of their actions on neurogenesis is essential, as it can be a leading pathway to therapeutic perspectives.

Othman, I.; Suman, H.

2008-01-01

Since the late 80's, Syria has been taking steps towards combating illicit trafficking or inadvertent movement involving radioactive or nuclear material within the country or across its border. By applying the proper combination of technical and procedural measures, an acceptable level of performance has been achieved. The measures undertaken by AECS include anticipative measures, which aim at identifying potential loss of control over radioactive sources and potential illicit trafficking within the country, as well as defensive measures which aim at detection of and response to events of illicit trafficking. In addition, a tight follow up of radiation source along their entire lifetime in the Syrian territory, supported by proper data analysis is one of the most efficient tools for identifying potential loss of control over sources. AECS has established Border Monitoring Centers (BMC) in almost all border crossings. They work in close cooperation with the customs and other relevant authorities at the Syrian borders. AECS has been also providing the necessary training for the frontline officers. (author)

Steroid Hormone Vitamin D: Implications for Cardiovascular Disease.

Science.gov (United States)

Demer, Linda L; Hsu, Jeffrey J; Tintut, Yin

2018-05-25

Understanding of vitamin D physiology is important because about half of the population is being diagnosed with deficiency and treated with supplements. Clinical guidelines were developed based on observational studies showing an association between low serum levels and increased cardiovascular risk. However, new randomized controlled trials have failed to confirm any cardiovascular benefit from supplementation in the general population. A major concern is that excess vitamin D is known to cause calcific vasculopathy and valvulopathy in animal models. For decades, administration of vitamin D has been used in rodents as a reliable experimental model of vascular calcification. Technically, vitamin D is a misnomer. It is not a true vitamin because it can be synthesized endogenously through ultraviolet exposure of the skin. It is a steroid hormone that comes in 3 forms that are sequential metabolites produced by hydroxylases. As a fat-soluble hormone, the vitamin D-hormone metabolites must have special mechanisms for delivery in the aqueous bloodstream. Importantly, endogenously synthesized forms are carried by a binding protein, whereas dietary forms are carried within lipoprotein particles. This may result in distinct biodistributions for sunlight-derived versus supplement-derived vitamin D hormones. Because the cardiovascular effects of vitamin D hormones are not straightforward, both toxic and beneficial effects may result from current recommendations. © 2018 American Heart Association, Inc.

2012-02-01

This study evaluated the degree to which anabolic-androgenic steroids are proffered for sale over the Internet and how they are characterized on popular Web sites. Searches for specific steroid product labels (e.g., Dianabol) between March 2006 and June 2006 revealed that approximately half of the Web sites advocated their "safe" use, and roughly one third offered to sell them without prescriptions. The Web sites frequently presented misinformation about steroids and minimized their dangers. Less than 5% of the Web sites presented accurate health risk information about steroids or provided information to abusers seeking to discontinue their steroid use. Implications for education, prevention, treatment, and policy are discussed.

Predictors of illicit drug/s use among university students in Northern Ireland, Wales and England.

El Ansari, Walid; Vallentin-Holbech, Lotte; Stock, Christiane

2014-12-16

The use of illicit drug/s among university students is a public health concern. Nevertheless, many UK studies investigated a narrow spectrum of variables to explore their association/s with illicit drug/s use. We assessed the associations between a wide range of socio-demographic, health and wellbeing variables (independent variables) and having used illicit drug/s regularly, occasionally or never in life (dependent variables). Data (3706 students) were collected from seven universities in England, Wales, and Northern Ireland, using a self-administered questionnaire. About 5% of the sample had regularly used illicit drug/s, 25% occasionally, and 70% never. Regular drug use (RDU) was significantly more likely among males aged 21-29 years, daily smokers, those with heavy episodic drinking or possible alcohol dependency (CAGE test), and those who perceived their academic performance better than their peers. RDU was less likely among students with high health awareness and those living with parents. The predictors of occasional drug use (ODU) were similar to those of RDU. However, in addition, students with higher perceived stress were less likely, and students who felt financial burden/s were more likely to report ODU, while no association with academic performance was found. Never use of illicit drug/s was inversely associated with most of the variables listed above, and was positively associated with religiosity. Illicit drug/s use goes along with other substance use (alcohol and smoking). The finding that illicit drug/s use was higher among students reporting good academic performance was surprising and raises the question of whether illicit drug/s may be used as performance enhancing drugs. The factors identified with illicit drug/s use in this study could be utilized to develop appropriate public health policies and preventive measures for the health of students. Multilevel, value based, comprehensive, and strategic long-term intervention plans are required. This

Measures for prevention illicit trafficking of nuclear and radioactive materials

International Nuclear Information System (INIS)

Strezov, A.

2002-01-01

Full text: In the early 1990ies the number of illicit trafficking cases with nuclear material and radioactive sources began to appear in the press more often than before. This fact became of great concern among international organizations and different states that the nuclear material subjected to trafficking might become in possession of rogue states and be implicated in weapons production or that stolen radioactive sources may cause health and safety effects to the population or to the environment. The creation and proposition of a model scheme procedure for the developing countries is important for starting the initial process of preventing and combating the illicit traffic of nuclear materials. Particular efforts have been directed for the protection of fissile materials. The reported incidents for diversion of nuclear materials have raised the problem of potential nuclear terrorism and also for countries of proliferation to take a short cut to the bomb. There is a need of rapid implementation of comprehensive, mutually reinforcing strategy to control the existing stockpiles of fissile material and to lower the future production and use of such materials. The illicit traffic of nuclear materials is a new threat, which requires new efforts, new approaches and coordination of services and institutions and even new legislation. The propositions of a model-procedure will allow better and quicker upgrade of developing countries capabilities for combating illicit nuclear trafficking. (author)

The analysis is performed using a difference-in-differences approach and the Synthetic Control Method in order to construct a synthetic control unit from a convex combination of countries. The results suggest that the prices of opiates and cocaine in the post-treatment period did not decrease in the sequence of the policy change. We conclude that the drug decriminalization policy seems to have caused no harm through lower illicit drugs prices, which would lead to higher drug usage and dependence.

Gebeyehu, G.

2002-01-01

Full text: The illicit uses of radioactive sources can impose a direct danger to public health and safety. A number of cases worldwide have resulted in ionizing radiation exposures to individuals. Although the incident of illicit trafficking is greatly influenced by the national system of protection of radioactive materials at their use and storage location this alone may not ensure an absolute guarantee against such occurrence. The challenges of preventing illicit use of radioactive sources and activities are more complex in the face of more integrated global economic environment. The national system of control, the cross border involvement, multiplicity of participants in the supply to end-use chain, diversity of systems and instruments are factors contributing to this complexity. Smooth interplay and overall systemic effectiveness of the national system of regulatory control, the strategic coordination of responsible parties and the systemic tie of such bodies, the efficiency of information flow and the pattern of know-how and training is what ensure the effectiveness of preventing, detecting and responding to any illicit activities and trafficking of radioactive sources. In Ethiopia, the attempts /incidents of illegal use were so far limited. However, the possibility of such occurrence cannot be ruled out and due attention should be paid as the activity is complex and is global problem of general concern. Therefore, in addressing these issues the following strategies are believed appropriate in Ethiopia's perspective for preventing and controlling illicit of use and trafficking of radioactive materials. Strengthening the national system of control and protection including boarder controlling; achieving effective coordination within and among regulators, law enforcement bodies and customs; developing and maintaining effective system of information handling and flow; training of principally responsible parties in the prevention, detection and response to illicit

Full Text Available Vernal Keratoconjunctivits (VKC is a bilateral recurrent allergic interstitial conjunctival inflammation with a periodic seasonal incidence and of self limiting nature, mainly affecting the younger population. Patients of VKC on steroid therapy are at higher risk of developing steroid induced glaucoma. Raised intraocular pressure due to steroids typically occurs within few weeks of starting steroid therapy and comes back to normal on immediate stoppage of steroids. A case of steroid induced glaucoma in a 30 years old female with vernal keratoconjunctivitis. She was on topical steroids for 3-4 years. She was incompliant with the instructions to stop steroids. She eventually developed steroid induced glaucoma and glaucomatous optic neuropathy with tunnel vision.

Prolonged steroid therapy is generally used for steroid-dependent nephrotic syndrome in pediatric patients. However, dwarfism secondary to a long-term regimen and its successful reverse is rarely reported. The underlying mechanism of dwarfism is still poorly understood, as both long-term steroid use and nephrotic syndrome may interact or independently interfere with the process of growth. Here, we present a 17-year-old patient with dwarfism and steroid-dependent nephrotic syndrome and the successful treatment by recombinant human growth factor and cyclosporine A with withdrawal of steroid. We also briefly review the current understanding and the management of dwarfism in pediatric patients with nephrotic syndrome.

A deregulation in the peripheral and brain concentrations of neuroactive steroids has been found in certain pathological conditions characterized by emotional or affective disturbances, including major depression and anxiety disorders. In this article we summarize data pertaining to the modulatory effects of oral contraceptive treatment on neuroactive steroids in women and rats. Given that the neuroactive steroids concentrations are reduced by oral contraceptives, together with the evidence that a subset of women taking oral contraceptives experience negative mood symptoms, we propose the use of this pharmacological treatment as a putative model to study the role of neuroactive steroids in the etiopathology of mood disorders. Moreover, since neuroactive steroids are potent modulators of GABA(A) receptor function and plasticity, the treatment with oral contraceptives might also represent a useful experimental model to further investigate the physiological role of these steroids in the modulation of GABAergic transmission.

Illicit trafficking of nuclear and other radioactive material: the 'net' security threat

Full text: Illicit trafficking in nuclear and other radioactive material, which could lead to the creation of a nuclear device or a radiological dispersal device (RDD), has been a subject of concern for more than a decade now. This concern became even more pronounced after the September 11 th attacks in the United States, which demonstrated that modern day terrorists are willing and capable of inflicting mass casualties among civilian population in target countries in order to further their goals. The problem of illicit trafficking - intentional diversion and smuggling of nuclear fissile material and radioactive sources - has been closely watched and studied by several national institutions and international organizations. This resulted in the establishment of several nuclear smuggling databases, tracking illicit trafficking incidents. The number of such incidents for a given period varies widely between the different databases, reflecting the different sources of information used, the different geographical regions covered, as well as the different methodologies applied to data mining and data analysis. One major obstacle to assessing the actual security threat due to illicit trafficking is the inclusion of incidents in the analysis, which do not represent a security threat in the sense of being the pre-stage of a terrorist operation or a malevolent act. Such incidents mainly involve inadvertent movement of illegally disposed of radioactive sources in scrap metal or contaminated goods across international borders and discoveries of so called 'orphan' radiation sources. This paper analyzes the global data contained in the database on nuclear smuggling, theft and orphan radiation sources (DSTO) operated by the University of Salzburg, using special filters to discriminate between illicit trafficking incidents involving a criminal intent and those that do not. Thereby, the net security threat of illicit trafficking will be determined to help provide a realistic

The aim of the study was to provide information on illicit drug abuse stigmata and general pathological findings among an adult narcotic drug-using population aged 20 to 59 years whose death was nonnatural. A total of 1603 medicolegal autopsy reports from 2000 to 2009 concerning cases positive for morphine, heroin, amphetamines, ecstasy, cannabis, LSD (lysergic acid diethylamide), PCP (phencyclidine), and high levels of GHB (γ-hydroxybutyric acid) in addition to methadone and buprenorphine were investigated. Reported findings of hepatitis, portal lymphadenopathy, recent injection marks, drug user's equipment, and numbers of significant pathological conditions were registered and analyzed according to cases positive for opiates, opioids (OPs), and central nervous system (CNS)-stimulating illicit drugs, respectively. Of the selected cases, 1305 were positive for one or more opiate or OP. Cases positive for OPs had significantly more findings of noninfectious pathological conditions. Hepatitis, portal lymphadenopathy, recent injections marks findings of drug user's equipment were all findings found more frequently among the opiate OP-positive individuals. Portal lymphadenopathy was significantly more often found in cases with hepatitis than in cases with other or no infection. In the population positive for CNS stimulants, hepatitis recent injection marks were more frequent findings than in the CNS stimulant-negative group, irrespective of whether they were opiate OP positive or negative.

Full Text Available In its progress, the criminal sanctions given to the convicted offenders of corruption are not effective. Therefore, in order to prevent corruption, the strategy needs a certain mechanism to criminalize the alleged offenders of corruption. The proper strategy is to provide a deterrent effect aims to impoverish corruptor. This study attempts to examine the regulations of corruption and offers alternative setting formulations of illicit enrichment as an effort to prevent the corruption. This research applies normative judicial method with statute approach and comparative approach. This study concludes that Indonesia doesn’t have regulations related to illicit enrichment; therefore the author offers an alternative on regulation of illicit enrichment as effort to eradicate corruption in Indonesia.

[Intramuscular depot steroids : Possible treatment of postsurgical cystoid macula edema with steroid response?

Seuthe, A-M; Szurman, P; Boden, K T

We report on a patient with postsurgical cystoid macular edema (CME) after phacoemulsification and multifocal intraocular lens (MIOL) implantation. At first, there was a very good reaction to intravitreal triamcinolone, inducing complete regression of the edema without increasing intraocular pressure (IOP). One year later the patient suffered from retinal detachment and was treated with vitrectomy, laser, and gas tamponade. Afterward, he developed macular pucker with edema. After surgical treatment with pucker peeling and intravitreal triamcinolone, the patient showed a steroid response and an increase IOP. Postoperatively, there was a recurrence of CME. A coincidental administration of a steroid injection intramuscularly by the general practitioner achieved a prompt reduction of the CME without increasing IOP. This case shows that an initially good reaction to triamcinolone without increasing IOP does not rule out a future steroid response, and that a potential treatment option for CME in patients with a known steroid response could consist of intramuscularly injected steroids.

Tobacco industry manipulation of data on and press coverage of the illicit tobacco trade in the UK.

In the UK, transnational tobacco companies (TTCs) have been arguing that levels of illicit trade are high and increasing and will rise further if standardised packaging is implemented. This paper examines trends in and accuracy of media reporting of, and industry data on, illicit tobacco in the UK. Quantification of the volume, nature and quality of press articles citing industry data on illicit tobacco in UK newspapers from March 2008 to March 2013. Examination of published TTC data on illicit, including a comparison with independent data and of TTC reporting of Her Majesty's Revenue and Customs data on illicit. Media stories citing industry data on illicit tobacco began in June 2011, 2 months after the Tobacco Control Plan for England, which heralded standardised packaging, was published. The majority of data cited are based on industry Empty Pack Surveys for which no methodology is available. For almost all parts of the country where repeat data were cited in press stories, they indicated an increase, often substantial, in non-domestic/illicit cigarettes that is not supported by independent data. Similarly, national data from two published industry sources show a sudden large increase in non-domestic product between 2011 and 2012. Yet the methodology of one report changes over this period and the other provides no published methodology. In contrast, independent data show steady declines in non-domestic and illicit cigarette penetration from 2006 to 2012 and either a continued decline or small increase to 2013. Industry claims that use of Non-UK Duty Paid/illicit cigarettes in the UK is sharply increasing are inconsistent with historical trends and recent independent data. TTCs are exaggerating the threat of illicit tobacco by commissioning surveys whose methodology and validity remain uncertain, planting misleading stories and misquoting government data. Industry data on levels of illicit should be treated with extreme caution. Published by the BMJ Publishing

Pharmacology of anabolic steroids.

Science.gov (United States)

Kicman, A T

2008-06-01

Athletes and bodybuilders have recognized for several decades that the use of anabolic steroids can promote muscle growth and strength but it is only relatively recently that these agents are being revisited for clinical purposes. Anabolic steroids are being considered for the treatment of cachexia associated with chronic disease states, and to address loss of muscle mass in the elderly, but nevertheless their efficacy still needs to be demonstrated in terms of improved physical function and quality of life. In sport, these agents are performance enhancers, this being particularly apparent in women, although there is a high risk of virilization despite the favourable myotrophic-androgenic dissociation that many xenobiotic steroids confer. Modulation of androgen receptor expression appears to be key to partial dissociation, with consideration of both intracellular steroid metabolism and the topology of the bound androgen receptor interacting with co-activators. An anticatabolic effect, by interfering with glucocorticoid receptor expression, remains an attractive hypothesis. Behavioural changes by non-genomic and genomic pathways probably help motivate training. Anabolic steroids continue to be the most common adverse finding in sport and, although apparently rare, designer steroids have been synthesized in an attempt to circumvent the dope test. Doping with anabolic steroids can result in damage to health, as recorded meticulously in the former German Democratic Republic. Even so, it is important not to exaggerate the medical risks associated with their administration for sporting or bodybuilding purposes but to emphasize to users that an attitude of personal invulnerability to their adverse effects is certainly misguided.

Despite growing numbers of older-adult illicit drug users, research on this topic is rare. This study examined the relationship between marijuana and/or other illicit drug use and major depressive episode (MDE) and serious suicidal thoughts among those aged 50+ years in the USA. The public use files of the 2008 to 2012 US National Survey on Drug Use and Health (NSDUH) provided data on 29,634 individuals aged 50+ years. Logistic regression analysis was used to test hypothesized associations between past-year marijuana and/or other illicit drug use and MDE and serious suicidal thoughts. Nearly 6% of the 50+ years age group reported past-year marijuana and/or other illicit drug use. Compared to non-users of any illicit drug, the odds of past-year MDE among those who used marijuana only, other illicit drugs only, and marijuana and other illicit drugs were 1.54 (95% CI = 1.17-2.03), 2.75 (95% CI = 1.75-4.33), and 2.12 (95% CI = 1.45-3.09), respectively. Those who used marijuana and other drugs also had higher odds (2.44, 95% CI = 1.58-3.77) of suicidal thoughts than non-users of any illicit drug. However, among users of any illicit drug, no difference was found among users of marijuana only, marijuana and other illicit drugs, and other illicit drugs only. Among marijuana users, marijuana use frequency was a significant correlate of suicidal thoughts only among those with MDE. Health and mental health (MH) service providers should pay close attention to the potential reciprocal effects of marijuana and other illicit drug use and MDE and suicidal thoughts among late middle-aged and older adults.

Full Text Available The purpose of the study was to determine the effect of ginseng-based steroid Rg1 on TNF-alpha and IL-10 gene expression in human skeletal muscle against exercise challenge, as well as on its ergogenic outcomes. Randomized double-blind placebo-controlled crossover trials were performed, separated by a 4-week washout. Healthy young men were randomized into two groups and received capsule containing either 5 mg of Rg1 or Placebo one night and one hour before exercise. Muscle biopsies were conducted at baseline, immediately and 3 h after a standardized 60-min cycle ergometer exercise. While treatment differences in glycogen depletion rate of biopsied quadriceps muscle during exercise did not reach statistical significance, Rg1 supplementations enhanced post-exercise glycogen replenishment and increased citrate synthase activity in the skeletal muscle 3 h after exercise, concurrent with improved meal tolerance during recovery (P<0.05. Rg1 suppressed the exercise-induced increases in thiobarbituric acids reactive substance (TBARS and reversed the increased TNF-alpha and decreased IL-10 mRNA of quadriceps muscle against the exercise challenge. PGC-1 alpha and GLUT4 mRNAs of exercised muscle were not affected by Rg1. Maximal aerobic capacity (VO2max was not changed by Rg1. However, cycling time to exhaustion at 80% VO2max increased significantly by ~20% (P<0.05.Our result suggests that Rg1 is an ergogenic component of ginseng, which can minimize unwanted lipid peroxidation of exercised human skeletal muscle, and attenuate pro-inflammatory shift under exercise challenge.

There is a strong link between HIV, smoking and illicit drugs. This association could be clinically relevant as it may potentiate the risk of cardiovascular diseases (CVD). The purpose of this review is to bring readers up to date on issues concerning the cardiovascular risk associated with tobacco and illicit drugs in patients living with HIV (PLHIV), examining the studies related to this topic published in the last year. There is a strong association between smoking and atherosclerotic disease in PLHIV, reducing life expectancy secondary to CVD by up to 6 years. Illicit drugs were associated with increased risk of atherosclerotic problems but to a lesser extent than smoking. A significant association of drugs such as cocaine with subclinical coronary atherosclerosis been demonstrated. The relation of marijuana, heroin and amphetamines with atherosclerosis generates more controversy. However, those drugs are associated with cardiovascular morbidity, independently of smoking and other traditional risk factors. Tobacco and illicit drugs are linked to CVD in HIV patients. This leads to the need to create special programs to address the addiction to smoking and illicit drugs, in order to mitigate their consequences and reduce cardiovascular risk.

Full text: The world has now become a global village as such no country can isolate itself from global trends. Reported cases of illicit trafficking in nuclear materials have focused international attention on ways to combat an emerging phenomenon of the 1990's. Of the 324 confirmed cases of illicit trafficking nearly 130 involved individuals trying to illegally sell radioactive materials used in medicine or industry whose unauthorized use or movement poses a danger to public health. Some other cases have involved samples of weapons-grade materials confiscated from individuals. These incidents have raised public and governmental concerns. This has prompted stronger efforts to prevent illicit nuclear trafficking by state authorities, including collaboration and co-operation with international organizational such as the IAEA. The IAEA has established the Illicit Trafficking Database Programme and is encouraging all Member States to participate and to report all incidents of illicit trafficking in nuclear materials and other radioactive materials and other radioactive sources that come to their notice. From the data available from the Regulatory Authority Information System (RAIS), Ghana, there are 344 highly enriched uranium fuel elements (998.2g) in use in the 30kW Research Reactor, (GHARR-1) and 80 radioactive materials in use in medicine, history, research and teaching. The reactor has been subjected to safeguards inspections by IAEA on regular basis. Additionally there have been on the average about nine authorized imports of radioactive into the country in the past seven years. Unlawful use of nuclear materials, through criminal or terrorist activities, may pose a proliferation treat, while unlawful use of radiation poses risks to the public. Ghana has therefore decided to established an effective counter measure against illicit trafficking in nuclear and other materials which might pose both proliferation threat as well as radiological risk to the public and

Thermal neutron activation analysis is based on neutron capture prompt gamma-ray analysis and has been used in wide variety of fields, for examples, for inspection of checked airline baggage and for detection of buried land mines. In all of these applications, the detected γ-ray intensities from the elements present are used to estimate their concentrations. A study about application using a trained neutral network is presented to determine the presence of illicit substances, such as explosives and drugs, carried out in the luggages. The illicit substances emit characteristic detected γ-ray which are the fingerprint of each isotope. The fingerprint data-base of the gamma-ray spectrum of substances is obtained via Monte Carlo N-Particle Transport code, MCNP, version 4B. It was possible to train the neural network to determine the presence of explosives and narcotics even hidden by several materials. (author)

The Analytic Laboratory of Israel Police processes illicit drug files. In recent years, workers of this laboratory have complained of health problems. Limited information exists on the effect of occupational exposure to illicit drugs; biomonitoring was never done. To assess health effects and systemic absorption of illicit drugs in workers of the Analytic Laboratory occupationally exposed to illicit drugs. A prospective cohort study using health and occupational questionnaires, clinical assessments, and monitoring of urinary excretion of illicit drugs was conducted. The study included three blocks of one week each. At each week workers were assessed at the beginning (baseline), and the assessments were repeated at the end of the three working days. Urine specimens were analyzed for illicit drugs in an independent laboratory. Demographic, clinical, occupational, and laboratory data were subjected to descriptive analysis, and paired Student's t-test, chi-square analysis, and repeated measures model. Twenty-seven workers (age, 39.2 ± 8.3 years; 77.8% females) were included, yielding 122 paired samples. The following parameters were reduced at the end of shift compared with baseline: diastolic blood pressure (71.2 ± 11.2 and 77.2 ± 13.6 mmHg, respectively, p health complaints included headache, fatigue, and dry eyes. No illicit drug was detected in the urine specimens. It is suggested that the health concerns of the laboratory workers were not related to the absorption of illicit drugs; environmental conditions (e.g. inadequate ventilation and respirable dust) can contribute to these concerns.

Full text: I Introduction - Vietnam has signed the Safeguard Agreement under NPT in 1989 and is preparing to join the Convention on Physical Protection of Nuclear Materials. To enhance the fulfillment of commitment, at the beginning of 1993 a joint group of experts from VAEC, Ministry of Defense and Ministry of Security was set up to: Search the current situation of illicit trafficking of nuclear and radioactive material; and Prevent the illicit trafficking. Activities were carried out during four years with modest resources and results achieved are remarkable, no case of illicit trafficking has been detected from 1997 until now. II Searching the illicit trafficking situation - The objectives of searching are the following: What is material in the illicit trafficking?; What is the motivation of illicit trafficking?; What is the illicit trafficking ploy? 1. Material in the illicit trafficking - At the end of the seventies and during the eighties, there were rumors of black trade of precious and mysterious metal with unbelievable high prices, higher many times than the gold price. Rumors said the name of the metal was uranium, black copper or osmium . We have collected all material confiscated during that time and during our activities, and the study shows: 516.56 kg of confiscated material is depleted uranium with U-235 mass content ranging from 0.2% to 0.32%, uranium mass content (U-235+U-238) ranging from 80% to 99%; Mostly pieces have a mark Made in USA. The masses of pieces range from 0.3 kg to 150 kg. By geometry and structure there are some mechanical parts of still unidentified machines; All pieces can be considered as radioactive material, the radioactive dose rate at their surface ranges from 10μSv/h to 100μSv/h. (Background: 0.2μSv/h); 268.65 kg confiscated material is false uranium made of lead. Its mark is written in very bad English trying to imitate the mark of real pieces. One false osmium body is made of silver. 2. Motivation of illicit

This research will be discuss how rule about the reversal burden of proof in the penal law system of Indonesia ? and how to application the reversal burden of proof in deprivation the illicit enrichment which is related with the human rights ?. Method used in this research is normative law research. Data analysis is conducted on primary and secondary law materials and then comparing those both as well were processed and presented by descriptive analysis. Related norm about the reversal burden of proof system now is regulated in act No. 31 of 1999, act No 20 of 2001 and act No. 8 of 2010, but the character of reversal burden of proof system in Indonesia still limited because it can only be used during the trials. Then related illicit enrichment norm is not regulated in Indonesia act’s, while Indonesia has been ratified about illicit enrichment in Article 20 UNCAC. The pros and cons related to the implementation of reversal burden of proof to illicit enrichment it happens because it is considered to against of human rights, which is related to the principle of presumption of innocence and non – self incrimination. However, with regard to other legal principles and consider the interests of the wider, the regulation of the illicit enrichment should be regulated in the provisions of the law in Indonesia.

Forty patients with clinical and/or histologically proven oral lichen planus were randomly placed into four groups and treated with topical triamcinolone, oral dapsone, topical tacrolimus or topical retinoid for three months. Pre- and post-treatment symptoms and signs were scored for each patient. Patients in all treatment groups showed significant clinical improvement after three months (p 0.05) and for topical retinoid vs topical tacrolimus (p > 0.05). Non-steroidal drugs such as dapsone, tacrolimus and retinoid are as efficacious as steroidal drugs for treating oral lichen planus, and avoid the side effects associated with steroids.

Full Text Available Herbal and nutritional supplements are more and more popular in the western population. One of them is an extract of an exotic plant, named Tribulus terrestris (TT. TT is a component of several supplements that are available over-the-counter and widely recommended, generally as enhancers of human vitality. TT is touted as a testosterone booster and remedy for impaired erectile function; therefore, it is targeted at physically active men, including male athletes. Based on the scientific literature describing the results of clinical trials, this review attempted to verify information on marketing TT with particular reference to the needs of athletes. It was found that there are few reliable data on the usefulness of TT in competitive sport. In humans, a TT extract used alone without additional components does not improve androgenic status or physical performance among athletes. The results of a few studies have showed that the combination of TT with other pharmacological components increases testosterone levels, but it was not discovered which components of the mixture contributed to that effect. TT contains several organic compounds including alkaloids and steroidal glycosides, of which pharmacological action in humans is not completely explained. One anti-doping study reported an incident with a TT supplement contaminated by a banned steroid. Toxicological studies regarding TT have been carried out on animals only, however, one accidental poisoning of a man was described. The Australian Institute of Sport does not recommend athletes’ usage of TT. So far, the published data concerning TT do not provide strong evidence for either usefulness or safe usage in sport.

Tobacco use is the leading cause of preventable disease and death in the United States. Increasing the unit price on tobacco products is the most effective tobacco prevention and control measure. Illicit tobacco trade (illicit trade) undermines high tobacco prices by providing tobacco users with cheaper-priced alternatives. In the United States, illicit trade primarily occurs when cigarettes are bought from states, jurisdictions, and federal reservation land with lower or no excise taxes, and sold in jurisdictions with higher taxes. Applying tax stamps to tobacco products, which provides documentation that taxes have been paid, is an important tool to combat illicit trade. Comprehensive tax stamping policy, which includes using digital, encrypted ("high-tech") stamps, applying stamps to all tobacco products, and working with tribes on stamping agreements, can further prevent and reduce illicit trade. This report describes state laws governing tax stamps on cigarettes, little cigars (cigarette-sized cigars), roll-your-own tobacco (RYOT), and tribal tobacco sales across the United States as of January 1, 2014, and assesses the extent of comprehensive tobacco tax stamping in the United States. Forty-four states (including the District of Columbia [DC]) applied traditional paper ("low-tech") tax stamps to cigarettes, whereas four authorized more effective high-tech stamps. Six states explicitly required stamps on other tobacco products (i.e., tobacco products other than cigarettes), and in approximately one third of states with tribal lands, tribes required tax stamping to address illicit purchases by nonmembers. No U.S. state had a comprehensive approach to tobacco tax stamping. Enhancing tobacco tax stamping across the country might further prevent and reduce illicit trade in the United States.

Full Text Available Topical steroids, commonly used for a wide range of skin disorders, are associated with side effects both systemic and cutaneous. This article aims at bringing awareness among practitioners, about the cutaneous side effects of easily available, over the counter, topical steroids. This makes it important for us as dermatologists to weigh the usefulness of topical steroids versus their side effects, and to make an informed decision regarding their use in each individual based on other factors such as age, site involved and type of skin disorder.

Brazil experienced a large decline in smoking prevalence between 2008 and 2013. Tax rate increases since 2007 and a new tobacco tax structure in 2012 may have played an important role in this decline. However, continuous tax rate increases pushed up cigarette prices over personal income growth and, therefore, some consumers, especially lower income individuals, may have migrated to cheaper illicit cigarettes. To use tobacco surveillance data to estimate the size of illicit tobacco consumption before and after excise tax increases. We defined a threshold price and compared it with purchasing prices obtained from two representative surveys conducted in 2008 and 2013 to estimate the proportion of illicit cigarette use among daily smokers. Generalised linear model was specified to understand whether the absolute difference in proportions over time differed by sociodemographic groups and consumption levels. Our findings were validated using an alternative method. Total proportion of illicit daily consumption increased from 16.6% to 31.1% between 2008 and 2013. We observed a pattern of unadjusted absolute decreases in cigarette smoking prevalence and increases in the proportion of illicit consumption, irrespective of gender, age, educational level, area of residence and amount of cigarettes consumed. The strategy of raising taxes has increased government revenues, reduced smoking prevalence and resulted in an increased illicit trade. Surveillance data can be used to provide information on illicit tobacco trade to help in the implementation of WHO Framework Convention on Tobacco Control (FCTC) article 15 and the FCTC Protocol to Eliminate Illicit Trade in Tobacco Products.

Steroid replacement without thyroxine supplementation normalizes thyroid function test (TFT) in some but not all Addison's disease patients with primary hypothyroidism. Both autoimmune and nonautoimmune mechanisms contribute to this improvement in TFT. However, the documentation of the change in thyroid autoimmunity after cortisol replacement is very limited in the literature. The aim of this study was to determine the effect of steroid replacement on TFT and anti-thyroid peroxidase antibody (anti-TPO-Ab) titer in Addison's disease with primary hypothyroidism. This observational study was conducted in a tertiary care center in South India. Six Addison's disease patients with primary hypothyroidism, who were only on steroid replacement, were included in the study. Low serum cortisol (22 pmol/L) and/or hyperpigmentation of skin/mucous membranes was considered as the diagnostic criteria for Addison's disease. Primary hypothyroidism (both overt and subclinical) was defined as high thyroid stimulating hormone (TSH) with/without low free thyroxine (fT4). TFT and anti-TPO-Ab were performed before and after steroid replacement in all of them. Poststeroid replacement, there was a normalization of TSH in all but one subjects. In overt hypothyroidism patients, fT4 also normalized. The improvement in TFT was not associated with decreasing titer of the anti-TPO-Ab in all six patients. However, there was a significant difference in TSH after steroid replacement compared to the baseline status. The concept of normalization of primary hypothyroidism with cortisol replacement in patients with Addison's disease should be recognized to avoid iatrogenic thyrotoxicosis caused by thyroxine replacement. Both autoimmune and nonautoimmune mechanisms contribute to these alterations.

Currently, dozens of anabolic androgenic steroids (AAS) are forbidden in the World Anti-Doping Agency Prohibited List, however, despite extensive investigation, there are still lots of AAS without corresponding monoclonal antibodies. A steroid analog antigen microarray made up of ten AAS was fabricated to screen the hybridoma and it was found an original unsuccessful clone turned out to be a candidate anti-boldenone antibody, without any cross-reactions with endogenous AAS or 44 different AAS standard reference materials tested. Our findings suggested that steroid analog antigen microarray could be a promising tool to screen and characterize new applications of antibodies for structure analogs, and this also exhibits the potential to fast identify effective epitopes of hybridomas in a single assay.

2016-01-01

Research into developing anabolic agents for various therapeutic purposes has been pursued for decades. As the clinical utility of anabolic-androgenic steroids has been found to be limited because of their lack of tissue selectivity and associated off-target effects, alternative drug entities have been designed and are commonly referred to as selective androgen receptor modulators (SARMs). While most of these SARMs are of nonsteroidal structure, the drug candidate MK-0773 comprises a 4-aza-steroidal nucleus. Besides the intended therapeutic use, SARMs have been found to be illicitly distributed and misused as doping agents in sport, necessitating frequently updated doping control analytical assays. As steroidal compounds reportedly undergo considerable metabolic transformations, the phase-I metabolism of MK-0773 was simulated using human liver microsomal (HLM) preparations and electrochemical conversion. Subsequently, major metabolic products were identified and characterized employing liquid chromatography-high-resolution/high- accuracy tandem mass spectrometry with electrospray (ESI) and atmospheric pressure chemical ionization (APCI) as well as nuclear magnetic resonance (NMR) spectroscopy. MK-0773 produced numerous phase-I metabolites under the chosen in vitro incubation reactions, mostly resulting from mono- and bisoxygenation of the steroid. HLM yielded at least 10 monooxygenated species, while electrochemistry-based experiments resulted predominantly in three monohydroxylated metabolites. Elemental composition data and product ion mass spectra were generated for these analytes, ESI/APCI measurements corroborated the formation of at least two N-oxygenated metabolites, and NMR data obtained from electrochemistry-derived products supported structures suggested for three monohydroxylated compounds. Hereby, the hydroxylation of the A-ring located N- bound methyl group was found to be of particular intensity. In the absence of controlled elimination studies, the

Are the tobacco industry's claims about the size of the illicit cigarette market credible? The case of South Africa.

Science.gov (United States)

van Walbeek, Corné; Shai, Lerato

2015-06-01

The tobacco industry claims that illicit cigarette trade in South Africa is high and rising. This is often used as an argument not to increase the tobacco excise tax or to regulate tobacco products. To determine how the tobacco industry's estimates of the size of the illicit cigarette market have changed over time. Published media articles were obtained from South African Press Cuttings; published articles and press releases were sourced from the internet. The period of interest is 1990-2012. Between 1990 and 2012 we found 90 newspaper articles and press statements that emphasised the tobacco industry's view on illicit trade. Articles that reported on action taken against illicit trade were excluded. Between 2006 and early 2011 the Tobacco Institute of Southern Africa, a body representing the interests of large cigarette companies, reported that South Africa's illicit cigarette market share was 20%. This share increased to 25% in late 2011 and 30% in 2012. In a 2012 presentation by Tobacco Institute of Southern Africa to National Treasury the illicit market share in 2008 was indicated as 7.9%, compared with claims in that year that the illicit market share was 20%. Industry findings that the illicit market decreased in 2007 and 2008 were not reported in the press. The tobacco industry has adjusted previous estimates of the illicit trade share downwards to create the impression that illicit trade is high and rising. If previous estimates by the tobacco industry were incorrect the credibility of current estimates should be questioned. Published by the BMJ Publishing Group Limited.

Large-scale internal migrations within China have led to speculation of increased drug use, but with little empirical evidence. This cross-sectional study examines the association between migration characteristics and illicit drug use in 100 general male migrants and 239 "money boys" (i.e., male migrants engaging in same-sex transactional sex) in Shanghai, China. Only three general male migrants reported any drug use. Among money boys, lifetime illicit drug use was 12%; Ecstasy and methamphetamine appeared to be the most popular drugs. In addition, depression prevalence was very high among both types of male migrants. Depression was associated with lifetime soft- and hard-drug use, while earning a higher income was associated with lifetime soft-drug use. These findings provide the first set of quantitative evidence of illicit drug use among Chinese male migrants. Although illicit drug use among male migrants is low compared to Western countries, its resurgence after 30 years of drug control gives cause for concern.

Inside athletes' minds: Preliminary results from a pilot study on mental representation of doping and potential implications for anti-doping

Full Text Available Abstract Background Despite the growing body of literature and putative links between the use of ergogenic nutritional supplements, doping and illicit drugs, it remains unclear whether, in athletes' minds, doping aligns with illicit behaviour or with functional use of chemical or natural preparations. To date, no attempt has been made to quantitatively explore athletes' mental representation of doping in relation to illegality and functionality. Methods A convenience sample of student athletes from a large South-Eastern Australian university responded to an on-line survey. Competitive athletes (n = 46 were grouped based on self-reported use as follows: i none used (30%, ii supplement only (22%, iii illicit only (26% and iv both supplements and illicit drug use (22%. Whereas no athlete reported doping, data provided on projected supplement-, doping- and drug use by the four user groups allowed evaluation of doping-related cognition in the context of self-reported supplement- and illicit drug taking behaviour; and comparison between these substances. Results A significantly higher prevalence estimation was found for illicit drug use and a trend towards a biased social projection emerged for supplement use. Doping estimates by user groups showed mixed results, suggesting that doping had more in common with the ergogenic nutritional supplement domain than the illicit drug domain. Conclusions Assessing the behavioural domain to which doping belongs to in athletes' mind would greatly advance doping behaviour research toward prevention and intervention. Further investigation refining the peculiarity of the mental representation of doping with a larger study sample, controlling for knowledge of doping and other factors, is warranted.

The aim of the present cross-sectional study was to examine illicit drug use and associations with socioeconomic factors as well as peer group influence among Brazilian adolescents aged 15 to 19 years. Two-stage cluster sampling was adopted, involving the random selection of public and private schools from the nine administrative districts of a Brazilian state capital and the random selection of classrooms at each school. Illicit drug use was the outcome and was measured through the question: "Have you ever used any illicit drugs (marijuana, inhalants, hypnotics, cocaine/crack, hallucinogens, amphetamines and opioids) in your life?". The most important group of friends was ranked as school, family, religious activities and sports/culture. The area-based Health Vulnerability Index (HVI) was used to assess socioeconomic status. Data from 891 adolescents were analyzed using the chi-squared test and logistic regression. The overall rate of illicit drug use was 15.2%. Gender heterogeneity within groups (OR = 3.14; 95%CI: 1.63-6.06), religion-based friendships (OR = 0.36; 95%CI: 0.17-0.75) and sports/culture-based friendships (OR = 0.44; 95%CI: 0.22-0.87) remained significantly associated with illicit drug use. Adolescents who lived in less vulnerable areas had higher chance of drug use in comparison with those living in more vulnerable areas. Religion-based and sports/culture-based friendships seem to demonstrate a protective effect against lifetime illicit drug use. Gender heterogeneity within groups and residing in a less vulnerable area increased the chances of adolescents reporting illicit drug use.

Illicit or rogue Internet pharmacies are a recognized global public health threat that have been identified as utilizing various forms of online marketing and promotion, including social media. To assess the accessibility of creating illicit no prescription direct-to-consumer advertising (DTCA) online pharmacy social media marketing (eDTCA2.0) and evaluate its potential global reach. We identified the top 4 social media platforms allowing eDTCA2.0. After determining applicable platforms (ie, Facebook, Twitter, Google+, and MySpace), we created a fictitious advertisement advertising no prescription drugs online and posted it to the identified social media platforms. Each advertisement linked to a unique website URL that consisted of a site error page. Employing Web search analytics, we tracked the number of users visiting these sites and their location. We used commercially available Internet tools and services, including website hosting, domain registration, and website analytic services. Illicit online pharmacy social media content for Facebook, Twitter, and MySpace remained accessible despite highly questionable and potentially illegal content. Fictitious advertisements promoting illicit sale of drugs generated aggregate unique user traffic of 2795 visits over a 10-month period. Further, traffic to our websites originated from a number of countries, including high-income and middle-income countries, and emerging markets. Our results indicate there are few barriers to entry for social media-based illicit online drug marketing. Further, illicit eDTCA2.0 has globalized outside US borders to other countries through unregulated Internet marketing.

In this study of wastewater treatment plants in three Canadian cities, selected illicit drugs, including cocaine and its major metabolite, benzoylecgonine (BE), amphetamine, methamphetamine and ecstasy (i.e. MDMA) were detected in untreated wastewater. Cocaine was the most widely used illicit drug at a median level for the 3 cities of 15.7 doses per day per 1000 people. For the other drugs, the median doses per day per 1000 people were 1.8 for amphetamine, 4.5 for methamphetamine and 0.4 for ecstasy. Methamphetamine use was highest in the largest city and cocaine use was lowest in the smallest city. Removal of the illicit drugs by wastewater treatment was generally >50%, except in a WWTP that uses primary treatment. The community consumption estimate for ecstasy in the present study is far below published estimates of the prevalence of ecstasy use among the Canadian population, which may be due to only occasional use of ecstasy. - Cocaine and amphetamines were detected in untreated and treated sewage in the wastewater treatment plants of three Canadian cities, and community consumption patterns estimated from the concentrations of the drugs in untreated wastewater were consistent with estimates of the use of illicit drugs in Canada.

Fischer, Benedikt; Kalousek, Kate; Rehm, Jürgen; Powis, Jeff; Krajden, Mel; Reimer, Jens

2006-01-01

Some 300,000 individuals are infected with the hepatitis C virus (HCV) in Canada. HCV infection is associated with major morbidity, mortality and health care costs; these indicators are projected to rise over the next decade. The vast majority of prevalent and incident HCV infections in Canada are illicit drug use-related; thus, the HCV disease burden can only be addressed through interventions targeting this primary risk factor. Both preventive (e.g., needle exchange, methadone treatment) and therapeutic (e.g., the accessibility of HCV treatment for illicit drug users) interventions aimed at HCV in illicit drug users have been broadly expanded in Canada in recent years. However, evidence suggests that existing preventive measures only offer limited effectiveness in reducing HCV risk exposure. Also, due to restricted resources, treatment for HCV currently only reaches an extremely small proportion (i.e., Canada is not achieving a net reduction in the prevalence of HCV-related to illicit drug use. In order to reduce the HCV disease burden, Canada needs to reconsider the scope, delivery and resourcing of both preventive and treatment interventions targeting the primary risk population of illicit drug users.

The purpose of this study was to investigate the association between depression and illicit drug dependence among a Latin-American population. illicit drug dependent patients (n = 137) and controls (n = 274) were interviewed using the Diagnostic Interview for Genetic Studies, in order to detect lifetime and current depressive disorder and illicit (cocaine, cannabis or inhalants) substance dependence. A regression analysis was used to estimate the odds ratio for drug dependence according to the diagnosis of depression. The lifetime diagnosis of depression (p = 0.001; OR = 4.9; 95% CI, 1.9-12.7) predicts illegal drugs dependence. Sociodemographic variables such as male gender (p drug dependence. Additional influent factors detected were having parents (p = 0.006; OR = 18.9; 95% CI, 2.3-158) or friends (p illicit drugs dependents. although a causal relationship between dependence on illicit drugs and depression cannot be determined, comparison of the sequence of events point to the occurrence of depression later in life than dependence. It remains to be determined whether depression is a comorbidity of dependence, sharing etiological factors, or a consequence of drug abuse and/or abstinence.

Cholestatic Jaundice With the Use of Methylstenbolone and Dymethazine, Designer Steroids Found in Super DMZ Rx 2.0 “Nutritional Supplement”

2014-04-01

Full Text Available “Nutritional supplements” that promise an increase in muscle mass and strength are becoming a go to item as enhancing one’s physical appearance becomes a more important part of our society. This is alarming because many of these nutritional supplements rely on androgen precursors to deliver their promises, without adequately informing consumers of the potential side effects of such agents. These products may conceal the presence of potent androgens to avoid regulatory sanctions and become more appealing to consumers. Recent reports have shown that some products marketed as “nutritional supplements” have been found to contain androgenic anabolic steroids. Methylstenbolone and dymethazine are new androgenic anabolic steroids currently gaining popularity among body builders for their performance-enhancing properties and rapid effects on muscle mass. These agents are found together in Super DMZ Rx 2.0, a “dietary supplement” for bodybuilders. Here we report the first case of Super DMZ Rx 2.0–induced cholestatic jaundice in a 26-year-old previously healthy Caucasian male, who took the supplement according to the manufacturer’s instructions for 30 days.

Illicit Cigarette Trade in Five South American Countries: A Gap Analysis for Argentina, Brazil, Chile, Colombia and Peru.

Science.gov (United States)

Paraje, Guillermo

2018-05-15

Due to its nature, it is very hard to measure tobacco illicit trade in any product. In the case of Latin American countries, there is scant information on the magnitude and characteristics of this trade in the case of cigarettes. The goal of this article is to provide estimates on the evolution of the illicit cigarette trade in five South American countries: Argentina, Brazil, Chile, Colombia and Peru. Gap analysis estimates for cigarette tax evasion/avoidance (a comparison on the evolution of the difference between registered cigarette sales and measured population consumption) is developed for Argentina, Brazil, Chile, Colombia and Peru. Nationally representative surveys, conducted regularly, are used to measure population consumption. Confidence intervals constructed by bootstrapping sample estimates are generated in order to statistically evaluate the evolution of the gap. Cigarette illicit trade has increased as a percentage of total sales in Brazil in recent years. In the case of Argentina, after a relative decrease between 2005 and 2009 it seems to have stabilized. There is no statistical evidence to argue that there has been an increase of cigarette illicit trade in Chile, Colombia and Peru, despite substantial price increases in Chile and tax increase in both Colombia and Peru. Using simple statistical methods, it is possible to assess the trend in tobacco illicit trend over time to better inform policy-makers. Getting reliable and regular population consumption surveys can also help to track tobacco illicit trade. Claims by tobacco industry of a positive association between price/tax changes and illicit trade are unsubstantiated. Evolution of cigarette illicit trade in five Latin American countries show different trajectories, not in line with tobacco industry estimates, which highlight the importance of producing solid, independent estimates. There are inexpensive methodologies that can provide estimates of the evolution of the relative importance of

All vertebrate embryos are exposed to maternally derived steroids during development. In placental vertebrates, metabolism of maternal steroids by the placenta modulates embryonic exposure, but how exposure is regulated in oviparous vertebrates is less clear. Recent work in oviparous vertebrates has demonstrated that steroids are not static molecules, as they can be converted to more polar steroid sulfates by sulfotransferase enzymes. Importantly, these steroid sulfates can be converted back to the parent compound by the enzyme steroid sulfatase (STS). We investigated when and where STS was present during embryonic development in the red-eared slider turtle, Trachemys scripta We report that STS is present during all stages of development and in all tissues we examined. We conclude that STS activity may be particularly important for regulating maternal steroid exposure in oviparous vertebrates. © 2017. Published by The Company of Biologists Ltd.

The tobacco industry claims that illicit trade in cigarettes has increased sharply since the 1990s and that government has lost substantial tax revenue. (1) To determine whether cigarette excise tax revenue has been below budget in recent years, compared with previous decades. (2) To determine trends in the size of the illicit market since 1995. For (1), mean percentage errors and root mean square percentage errors were calculated for budget revenue deviation for three products (cigarettes, beer and spirits), for various subperiods. For (2), predicted changes in total consumption, using actual cigarette price and GDP changes and previously published price and income elasticity estimates, were calculated and compared with changes in tax-paid consumption. Cigarette excise revenues were 0.7% below budget for 2000-2012 on average, compared with 3.0% below budget for beer and 4.7% below budget for spirits. There is no evidence that illicit trade in cigarettes in South Africa increased between 2002 and 2009. There is a substantial increase in illicit trade in 2010, probably peaking in 2011. In 2012 tax-paid consumption of cigarettes increased 2.6%, implying that the illicit market share decreased an estimated 0.6 percentage points. Other than in 2010, there is no evidence that illicit trade is significantly undermining government revenue. Claims that illicit trade has consistently increased over the past 15 years, and has continued its sharp increase since 2010, are not supported. Published by the BMJ Publishing Group Limited.

Pharmaceutically active substances (PhACs) and drugs of abuse (DAs) are two classes of contaminants of emerging concern that have attracted great concern and interest by the scientific community during the last two decades. Numerous studies have revealed their presence in treated urban wastewaters. This is mainly due to the fact that some compounds are not efficiently removed during wastewater treatment processes, and are thus able to reach the aquatic environment through wastewater discharge and reuse practices. The application of an optimized multi-residue method for the simultaneous confirmation and quantification of licit and illicit drugs has been investigated in influent and effluent wastewater samples from seven wastewater treatment plants (WWTPs) located in north-eastern Tunisia. Analysis was performed through ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). Out of 12 pharmaceutical compounds analyzed, 11 of them were detected mainly in effluent wastewaters. In both matrices, antibiotics and β-blockers were the most detected groups. This suggests that these compounds show noticeable resistance against biological treatment in WWTPs. The estimated concentrations of antibiotics in effluents ranged from ca. 35 ng/L to 1.2 μg/L. However, all five studied illicit drugs were detected, mainly in influent wastewaters. Forensic investigation performed on people suspected to be drug abusers covering all Tunisian cities was conducted by monitoring an epidemiological study of human urine samples surveying rate of consumption for illicit drugs. Hence, these preliminary results confirmed the presence of illicit drugs in the influent wastewater samples. For example, quantification ranges for cocaine were found to be 25-450 ng/L in influent wastewater samples. Significant differences for cocaine consumption across the two sampling methods were observed. Consequently, we conclude that the analyses in wastewater are more reflective of the

Background Illicit or rogue Internet pharmacies are a recognized global public health threat that have been identified as utilizing various forms of online marketing and promotion, including social media. Objective To assess the accessibility of creating illicit no prescription direct-to-consumer advertising (DTCA) online pharmacy social media marketing (eDTCA2.0) and evaluate its potential global reach. Methods We identified the top 4 social media platforms allowing eDTCA2.0. After determining applicable platforms (ie, Facebook, Twitter, Google+, and MySpace), we created a fictitious advertisement advertising no prescription drugs online and posted it to the identified social media platforms. Each advertisement linked to a unique website URL that consisted of a site error page. Employing Web search analytics, we tracked the number of users visiting these sites and their location. We used commercially available Internet tools and services, including website hosting, domain registration, and website analytic services. Results Illicit online pharmacy social media content for Facebook, Twitter, and MySpace remained accessible despite highly questionable and potentially illegal content. Fictitious advertisements promoting illicit sale of drugs generated aggregate unique user traffic of 2795 visits over a 10-month period. Further, traffic to our websites originated from a number of countries, including high-income and middle-income countries, and emerging markets. Conclusions Our results indicate there are few barriers to entry for social media–based illicit online drug marketing. Further, illicit eDTCA2.0 has globalized outside US borders to other countries through unregulated Internet marketing. PMID:23718965

Countries from Southern Africa have formed a Development Community (SADC) to stimulate common actions in several areas, among them illicit drugs combat. In this context, the goal of this qualitative study was to identify information and perception about the cooperation set up between Mozambique and other SADC members in combatting illicit drugs. Data were collected through semi-structured interviews with public employees developing actions directed at the implementation of the Protocol to Combat Drugs in SADC. After transcriptions, the interviews were analyzed by content analysis and resulted in the categories: "Mozambique as a drugs corridor", "Cooperation Initiatives on Drugs among African countries", "Cooperation Difficulties in Africa", "Problems in Protocol Implementation" and "Difficulties to implement a control policy". As a consequence, there is a need to review and update the policies and strategies in the drugs area, as they are not contextualized in the country's current reality.

Background: Steroid replacement without thyroxine supplementation normalizes thyroid function test (TFT) in some but not all Addison's disease patients with primary hypothyroidism. Both autoimmune and nonautoimmune mechanisms contribute to this improvement in TFT. However, the documentation of the change in thyroid autoimmunity after cortisol replacement is very limited in the literature. The aim of this study was to determine the effect of steroid replacement on TFT and anti-thyroid peroxidase antibody (anti-TPO-Ab) titer in Addison's disease with primary hypothyroidism. Materials and Methods: This observational study was conducted in a tertiary care center in South India. Six Addison's disease patients with primary hypothyroidism, who were only on steroid replacement, were included in the study. Low serum cortisol (22 pmol/L) and/or hyperpigmentation of skin/mucous membranes was considered as the diagnostic criteria for Addison's disease. Primary hypothyroidism (both overt and subclinical) was defined as high thyroid stimulating hormone (TSH) with/without low free thyroxine (fT4). TFT and anti-TPO-Ab were performed before and after steroid replacement in all of them. Results: Poststeroid replacement, there was a normalization of TSH in all but one subjects. In overt hypothyroidism patients, fT4 also normalized. The improvement in TFT was not associated with decreasing titer of the anti-TPO-Ab in all six patients. However, there was a significant difference in TSH after steroid replacement compared to the baseline status. Conclusions: The concept of normalization of primary hypothyroidism with cortisol replacement in patients with Addison's disease should be recognized to avoid iatrogenic thyrotoxicosis caused by thyroxine replacement. Both autoimmune and nonautoimmune mechanisms contribute to these alterations. PMID:27042409

Bacterial infections, including Bacillus anthracis (anthrax), are a common risk associated with illicit drug use, particularly among injecting drug users. There is, therefore, an urgent need to survey illicit drugs used for injection for the presence of bacteria and provide valuable information to health and forensic authorities. The objectives of this study were to develop a method for the extraction of bacterial DNA from illicit drugs and conduct a metagenomic survey of heroin and methamphetamine seized in the Australian Capital Territory during 2002-2011 for the presence of pathogens. Trends or patterns in drug contamination and their health implications for injecting drug users were also investigated. Methods based on the ChargeSwitch(®)gDNA mini kit (Invitrogen), QIAamp DNA extraction mini kit (QIAGEN) with and without bead-beating, and an organic phenol/chloroform extraction with ethanol precipitation were assessed for the recovery efficiency of both free and cellular bacterial DNA. Bacteria were identified using polymerase chain reaction and electrospray ionization-mass spectrometry (PCR/ESI-MS). An isopropanol pre-wash to remove traces of the drug and diluents, followed by a modified ChargeSwitch(®) method, was found to efficiently lyse cells and extract free and cellular DNA from Gram-positive and Gram-negative bacteria in heroin and methamphetamine which could then be identified by PCR/ESI-MS. Analysis of 12 heroin samples revealed the presence of DNA from species of Comamonas, Weissella, Bacillus, Streptococcus and Arthrobacter. No organisms were detected in the nine methamphetamine samples analysed. This study develops a method to extract and identify Gram-positive and Gram-negative bacteria from illicit drugs and demonstrates the presence of a range of bacterial pathogens in seized drug samples. These results will prove valuable for future work investigating trends or patterns in drug contamination and their health implications for injecting drug

ent-Steroids: novel tools for studies of signaling pathways.

Science.gov (United States)

Covey, Douglas F

2009-07-01

Membrane receptors are often modulated by steroids and it is necessary to distinguish the effects of steroids at these receptors from effects occurring at nuclear receptors. Additionally, it may also be mechanistically important to distinguish between direct effects caused by binding of steroids to membrane receptors and indirect effects on membrane receptor function caused by steroid perturbation of the membrane containing the receptor. In this regard, ent-steroids, the mirror images of naturally occurring steroids, are novel tools for distinguishing between these various actions of steroids. The review provides a background for understanding the different actions that can be expected of steroids and ent-steroids in biological systems, references for the preparation of ent-steroids, a short discussion about relevant forms of stereoisomerism and the requirements that need to be fulfilled for the interaction between two molecules to be enantioselective. The review then summarizes results of biophysical, biochemical and pharmacological studies published since 1992 in which ent-steroids have been used to investigate the actions of steroids in membranes and/or receptor-mediated signaling pathways.

To evaluate the effects of oral steroids alone or followed by intranasal steroids versus watchful waiting on the resolution of otitis media with effusion in children aged 2-11 years. A total of 290 children with bilateral otitis media with effusion were assigned to 3 groups: group A was treated with oral steroids followed by intranasal steroids, group B was treated with oral steroids alone and group C was managed with watchful waiting. Patients were evaluated with audiometry and tympanometry. The complete resolution rates of otitis media with effusion were higher in groups A and B than in group C at six weeks. There were no significant differences in otitis media with effusion resolution rates between the groups at three, six and nine months. Oral steroids lead only to a quick resolution of otitis media with effusion, with no long-term benefits. There was no benefit of using intranasal steroids in the management of otitis media with effusion.

Use of [125I]-iodohistamine-labelled steroid derivatives as radioligands for radioimmunoassay of natural and synthetic steroids

Stanczyk, F.Z.; Goebelsmann, U.

1981-01-01

[ 125 I]-Iodohistamine-labelled steroid derivatives were prepared and utilized as radioligands in radioimmunoassays of progesterone, testosterone, estradiol, estriol, estriol-16α-glucuronide, levonorgestrel, norethindrone and medroxyprogesterone acetate. The binding of these iodinated radioligands was compared to that of the corresponding tritiated steroids and their effect on the sensitivity and slope of standard curves was examined. The results demonstrate that much higher antibody dilutions could be used with iodinated than with tritiated radioligands. In general, standard curves obtained with iodinated radioligands were more sensitive than those obtained with tritiated steroids, but standard curves had steeper slopes when tritiated rather than iodinated radioligands were used. The data, summarizing our 5-year experience with steroid-[ 125 I]-iodohistamine derivatives, indicate that these tracers play an important role in radioimmunoassay systems for both natural and synthetic steroids.

Murakami, Tadashi

1975-01-01

Low acid pepsin treated gamma-globulin was applied to ammonium sulfate salting out method, which was a method to separate bound fraction from free one in radioimmunoassay of steroid hormone, and the effect of the separation and the standard curve were examined. Pepsin treated gamma-globulin was prepared in pH 1.5 to 5.5 and then the pepsin was completely removed. It had an effect to accelerate the precipitation in radioimmunoassay of steroid hormone labelled with 3 H. The effect of pepsin treated gamma-globulin to adhere free steroid hormone and to slat out bound one was compared with that of human gamma-globulin. Pepsin treated gamma-globulin, which was water soluble, could easier reach its optimal concentration, and the separation effect was better than human gamma-globulin. The standard curve of it was steeper, particularly in a small dose, and the reproducibility was also better. It could be applied not only to aldosterone and DOC, but also to the steroid hormones, such as progesterone and DHEA, and it seemed suitable for routine measurement method. (Kanao, N.)

To estimate the prevalence and factors associated with illicit drug use by adolescents and young adults of a formal urban settlement. Cross-sectional study including adolescents and young adults 12-24 years of an urban settlement in the Midwest Region of Brazil. Data were collected using a structured questionnaire and analyzed using Stata, version 12.0. We used Poisson regression model to estimate the factors associated with illicit drug use. Of the total participants (n=105), 27.6% (95CI 20.0-36.9%) had used illicit drugs such as marijuana, cocaine, crack, LSD and inhalants. The consumption of these substances was associated with male gender, use of body piercing and/or tattoos, licit drug use and self-report of signs and/or symptoms of sexually transmitted infections. High prevalence of illicit drug use was found in the individuals investigated, ratifying the presence of risk factors to the vulnerability of the settlers to use these substances in the urban settlement population.

Cryptomarkets are online marketplaces that are part of the Dark Web and mainly devoted to the sale of illicit drugs. They combine tools to ensure anonymity of participants with the delivery of products by mail to enable the development of illicit drug trafficking. Using data collected on eight cryptomarkets, this study provides an overview of the Canadian illicit drug market. It seeks to inform about the most prevalent illicit drugs vendors offer for sale and preferred destination countries. Moreover, the research gives an insight into the structure and organisation of distribution networks existing online. In particular, we provide information about how vendors are diversifying and replicating across marketplaces. We inform on the number of listings each vendor manages, the number of cryptomarkets they are active on and the products they offer. This research demonstrates the importance of online marketplaces in the context of illicit drug trafficking. It shows how the analysis of data available online may elicit knowledge on criminal activities. Such knowledge is mandatory to design efficient policy for monitoring or repressive purposes against anonymous marketplaces. Nevertheless, trafficking on Dark Net markets is difficult to analyse based only on digital data. A more holistic approach for investigating this crime problem should be developed. This should rely on a combined use and interpretation of digital and physical data within a single collaborative intelligence model. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

To determine whether prenatal and perinatal maternal consumption of alcohol, tobacco and/or illicit drugs is associated with risk of neuroblastoma. Medline and Embase (both from inception to February 2017), and reference lists of included studies. To be eligible, a study had to be an original report including data on intake of alcohol, tobacco smoking and/or consumption of illicit drugs during pregnancy and risk of neuroblastoma in the child. From eligible studies, data study characteristics as well as effect measures and confounders were extracted. We assessed unadjusted and confounder-adjusted estimates, performed risk of bias analysis, constructed random-effects models and assessed heterogeneity. We identified 14 case-control studies (1987-2016) involving a total of 3114 children with neuroblastoma. Meta-analysis of unadjusted estimates showed an association between alcohol (OR 1.26; 95% CI 1.07 to 1.49), tobacco (OR 1.22; 95% CI 1.04 to 1.44) and illicit drug consumption during pregnancy and risk of neuroblastoma during childhood, with illicit drug consumption showing the strongest association (OR 3.26; 95% CI 1.36 to 7.86). However, adjusted estimates were highly heterogeneous. All studies were at high risk of bias. Smoking, alcohol or illicit drugs during pregnancy might play a role in the development of neuroblastoma. However, well-designed studies are needed to assess whether these exposures are causal and whether time period during pregnancy, dose or co-consumption of substances is critical.

Substantiation of drug exposure in cases with alleged maltreatment is important to provide proper treatment and services to these children and their families. A study performed at University of Iowa Hospitals and Clinics showed that 30% of pediatric patients with burn injuries, which were due to child maltreatment, were also exposed to illicit drugs. The children presenting to the University of Iowa Hospitals and Clinics with alleged maltreatment have been tested for illicit substances since 2004. The objective of this study was to analyze the presence of illicit drug exposure in the pediatric subpopulation admitted to pediatric inpatient and outpatient units for an evaluation for abuse/neglect. The study design is a retrospective chart review. Using hospital databases, every pediatric chart with a child abuse/neglect allegation was retrieved. The association between risk factors and clinical presentation and illicit drug test result was assessed. Excel and SAS were used for statistical analysis. Institutional review board approval was obtained to conduct this study. Six hundred sixty-five charts met study inclusion criteria for child abuse/neglect allegation. Of those, 232 cases were tested for illicit drugs between 2004 and 2008 per the testing protocol. Thirty-four cases (14.7%) tested positive on a drug test. Positive test rates based on clinical presentation were 28.6% (18/63) in neglect cases, 16.1% (5/31) in cases with soft tissue injuries, 14.3% (4/28) in burn injuries, 10.0% (2/20) in cases with sexual abuse, 7.1% (2/28) in cases with fractures, and 4.8% (3/62) in abusive head trauma cases. There were long-term abuse findings in 129 children (55.6%). Logistic regression analysis revealed that positive drug testing was most significantly associated with clinical symptoms suggesting physical abuse or neglect versus sexual abuse (odds ratio [OR] = 6.70; 95% confidence interval [CI], 1.26-35.49; P = 0.026), no or public health insurance versus those with

Brain nonapeptide and gonadal steroid responses to deprivation of heterosexual contact in the black molly

Directory of Open Access Journals (Sweden)

Ewa Kulczykowska

2014-12-01

Full Text Available Fish may respond to different social situations with changes in both physiology and behaviour. A unique feature of fish is that social interactions between males and females strongly affect the sexual characteristics of individuals. Here we provide the first insight into the endocrine background of two phenomena that occur in mono-sex groups of the black molly (Poecilia sphenops: masculinization in females and same-sex sexual behaviour, manifested by gonopodial displays towards same-sex tank mates and copulation attempts in males. In socially controlled situations, brain neurohormones impact phenotypic sex determination and sexual behaviour. Among these hormones are the nonapeptides arginine vasotocin (AVT and isotocin (IT, counterparts of the well-known mammalian arginine vasopressin and oxytocin, respectively. To reveal potential hormone interactions, we measured the concentrations of bioactive AVT and IT in the brain, along with those of the sex steroids 17β-estradiol and 11-ketotestosterone in the gonads, of females, masculinized females, males displaying same-sex sexual behaviour and those who did not. These data were supplemented by morphological and histological analyses of the gonads. Correlations between brain nonapeptides and gonadal steroids strongly suggest a cross talk between hormonal systems. In the black molly, the masculinization process was associated with the production of brain AVT and gonadal steroids, whereas same-sex sexual behaviour involves both brain nonapeptides, but neither of the sex steroids. This study extends current knowledge of endocrine control of phenotypic sex and sexual behaviour in fish and for the first time links brain nonapeptides with the occurrence of male-male sexual behaviour in lower vertebrates.

The aim of this study was to investigate the impact of the use of crack and other illicit drugs on oral health-related quality of life (OHRQoL) in young adults. This cross-sectional study evaluated 106 crack users at a public treatment center for drug addiction and 106 controls matched for gender, age, and use of tobacco. Clinical examinations were performed for dental caries and periodontal disease. The outcome was OHRQoL, which was determined using the Oral Health Impact Profile (OHIP-14). The association between OHRQoL and illicit drugs was modeled using conditional Poisson regression. Users of crack and other illicit drugs had a poorer OHRQoL than the controls (p illicit drugs. Users of crack and other illicit drugs exerted a negative impact on OHRQoL independently of socio-demographic characteristics and tobacco use, suggesting the need for special attention regarding the specific oral health needs of this population as well as drug prevention and treatment strategies. © 2017 John Wiley & Sons A/S.

Nguyen, Tuong-Vi; Ducharme, Simon; Karama, Sherif

2017-11-01

Sex steroids are thought to play a critical developmental role in shaping both cortical and subcortical structures in the human brain. Periods of profound changes in sex steroids invariably coincide with the onset of sex differences in mental health vulnerability, highlighting the importance of sex steroids in determining sexual differentiation of the brain. Yet, most of the evidence for the central effects of sex steroids relies on non-human studies, as several challenges have limited our understanding of these effects in humans: the lack of systematic assessment of the human sex steroid metabolome, the different developmental trajectories of specific sex steroids, the impact of genetic variation and epigenetic changes, and the plethora of interactions between sex steroids, sex chromosomes, neurotransmitters, and other hormonal systems. Here we review how multimodal strategies may be employed to bridge the gap between the basic and clinical understanding of sex steroid-related changes in the human brain.

Dietary Supplements and Sports Performance: Introduction and Vitamins

Williams Melvin H

2004-12-01

Full Text Available Abstract Sports success is dependent primarily on genetic endowment in athletes with morphologic, psychologic, physiologic and metabolic traits specific to performance characteristics vital to their sport. Such genetically-endowed athletes must also receive optimal training to increase physical power, enhance mental strength, and provide a mechanical advantage. However, athletes often attempt to go beyond training and use substances and techniques, often referred to as ergogenics, in attempts to gain a competitive advantage. Pharmacological agents, such as anabolic steroids and amphetamines, have been used in the past, but such practices by athletes have led to the establishment of anti-doping legislation and effective testing protocols to help deter their use. Thus, many athletes have turned to various dietary strategies, including the use of various dietary supplements (sports supplements, which they presume to be effective, safe and legal.

In Vitro Androgen Bioassays as a Detection Method for Designer Androgens

Directory of Open Access Journals (Sweden)

Alison K. Heather

2013-02-01

Full Text Available Androgens are the class of sex steroids responsible for male sexual characteristics, including increased muscle mass and decreased fat mass. Illicit use of androgen doping can be an attractive option for those looking to enhance sporting performance and/or physical appearance. The use of in vitro bioassays to detect androgens, especially designer or proandrogens, is becoming increasingly important in combating androgen doping associated with nutritional supplements. The nutritional sports supplement market has grown rapidly throughout the past decade. Many of these supplements contain androgens, designer androgens or proandrogens. Many designer or proandrogens cannot be detected by the standard highly-sensitive screening methods such as gas chromatography-mass spectrometry because their chemical structure is unknown. However, in vitro androgen bioassays can detect designer and proandrogens as these assays are not reliant on knowing the chemical structure but instead are based on androgen receptor activation. For these reasons, it may be advantageous to use routine androgen bioassay screening of nutraceutical samples to help curb the increasing problem of androgen doping.

Full Text Available Background: Steroid replacement without thyroxine supplementation normalizes thyroid function test (TFT in some but not all Addison's disease patients with primary hypothyroidism. Both autoimmune and nonautoimmune mechanisms contribute to this improvement in TFT. However, the documentation of the change in thyroid autoimmunity after cortisol replacement is very limited in the literature. The aim of this study was to determine the effect of steroid replacement on TFT and anti-thyroid peroxidase antibody (anti-TPO-Ab titer in Addison's disease with primary hypothyroidism. Materials and Methods: This observational study was conducted in a tertiary care center in South India. Six Addison's disease patients with primary hypothyroidism, who were only on steroid replacement, were included in the study. Low serum cortisol (22 pmol/L and/or hyperpigmentation of skin/mucous membranes was considered as the diagnostic criteria for Addison's disease. Primary hypothyroidism (both overt and subclinical was defined as high thyroid stimulating hormone (TSH with/without low free thyroxine (fT4. TFT and anti-TPO-Ab were performed before and after steroid replacement in all of them. Results: Poststeroid replacement, there was a normalization of TSH in all but one subjects. In overt hypothyroidism patients, fT4 also normalized. The improvement in TFT was not associated with decreasing titer of the anti-TPO-Ab in all six patients. However, there was a significant difference in TSH after steroid replacement compared to the baseline status. Conclusions: The concept of normalization of primary hypothyroidism with cortisol replacement in patients with Addison's disease should be recognized to avoid iatrogenic thyrotoxicosis caused by thyroxine replacement. Both autoimmune and nonautoimmune mechanisms contribute to these alterations.

Diversion of opioid substitution drugs (OSD) is of public concern. This study examined the prevalence, frequency, and predictors of illicit OSD use in a group of injecting drug users (IDUs) and assessed if such use was associated with non-fatal overdoses. Semi-annual cross-sectional interviews conducted in Oslo, Norway (2006-2013), from 1355 street-recruited IDUs. Hurdle, logistic, and multinomial regression models were employed. Overall, 27% reported illicit OSD use in the past four weeks; 16.8% methadone, 12.5% buprenorphine, and 2.9% both drugs. Almost 1/10 reported at least one non-fatal overdose in the past four weeks, and roughly 1/3 reported such experience in the past year. Use of additional drugs tended to be equally, or more prevalent among illicit OSD users than other IDUs. In terms of illicit OSD use being a risk factor for non-lethal overdoses, our results showed significant associations only for infrequent buprenorphine use (using once or less than once per week). Other factors associated with non-fatal overdoses included age, education, homelessness, as well as the benzodiazepines, stimulants, and heroin use. Users of diverted OSD may represent a high-risk population, as they used more additional drugs and used them more frequently than other IDUs. However, illicit OSD use may be less harmful than previously assumed. After accounting for an extensive set of covariates, only infrequent illicit buprenorphine use, but not methadone use, was associated with non-fatal overdoses. Copyright © 2014 Elsevier Ireland Ltd.

Objective This study was performed to confirm the efficacy of long-interval cytapheresis on steroid-dependent ulcerative colitis (UC). Methods To discontinue steroids in patients with steroid-dependent UC, we previously designed a novel regimen of cytapheresis (CAP), which we termed "long-interval cytapheresis (LI-CAP)", in which CAP was performed as one session every two or three weeks and continued during the whole period of tapering steroid dosage. In this study, we performed LI-CAP therapy 20 times (11 male and 9 female; mean age 41.8 years) between April 2010 and April 2015 for 14 patients with steroid-dependent UC. We evaluated the effectiveness of LI-CAP by examining the improvement in Lichtiger's clinical activity index (CAI), the rate of clinical remission, and the rate of steroid discontinuation. We further examined the rate of sustained steroid-free clinical remission at 6 and 12 months after LI-CAP in patients who successfully discontinued steroid-use after LI-CAP. The primary endpoint was the rate of discontinuation of steroids after LI-CAP. Results The mean CAI score before LI-CAP (7.550) significantly decreased to 1.65 after LI-CAP (psteroid discontinuation after LI-CAP was 60.0%. The mean dose of daily prednisolone was significantly decreased after LI-CAP (2.30 mg) compared with that before therapy (17.30 mg) (p=0.0003). The rate of sustained steroid-free clinical remission after LI-CAP was 66.7% at 6 months and 66.7% at 12 months. Conclusion We confirmed that LI-CAP has therapeutic effects on reducing the dosage and discontinuing steroids in patients with steroid-dependent UC.

People who inject drugs (PWID) are a key population engaging in pharmaceutical opioid analgesic (PO) use, yet little is known about patterns of illicit PO use among this group. The aims of this research were to measure the prevalence and frequency of lifetime and past-month illicit PO use and injection in a sample of regular PWID, to examine patterns of past-month illicit PO use within individuals over time, and to identify factors independently associated with past-month illicit PO use. Data were drawn from a prospective cohort study of regular PWID (N = 666) in Melbourne, Australia. Data from five waves of annual data collection (including baseline) were analyzed descriptively and using generalized estimating equations (GEE). At baseline, 59% of participants reported lifetime illicit PO use and 20% reported past-month use, predominantly through injecting. Most illicit PO users at baseline transitioned to nonuse of illicit POs across the study period. In multivariable GEE analysis, factors associated with past-month illicit PO use included past-year arrest [adjusted odds ratio (AOR): 1.39], opioids other than heroin as drug of choice (AOR: 5.14), experiencing poorer physical health (AOR: 0.98) and a range of other drug use variables. We found little evidence of ongoing illicit PO use among those followed up, with illicit PO use linked to polydrug use more broadly. Nonetheless, trends in illicit PO use among PWID should continue to be monitored and harm reduction interventions implemented to reduce the associated public health risks.

Steroid acne is a folliculitis that can result from systemic or topical administration of steroid, and has been described as showing a similar clinical picture to Pityrosporum folliculitis, but there have been few reports about the incidence of Pityrosporum ovale and the effect of antimycotic drugs in steroid acne and other acneiform eruptions. Our purpose was to describe the association between steroid acne and P. ovale, and to confirm the superior efficacy of oral antifungal drugs over anti-acne drugs in the treatment of steroid acne. The history, clinical features direct microscopy, histopathologic analysis, and therapeutic results of 125 cases with steroid acne or other acneiform eruptions were described and compared. Over 80% of patients with acneiform eruption receiving systemic steroid revealed significant numbers of P. ovale in the lesional follicle. Furthermore, oral antifungal drug (itraconazole) showed significantly better clinical and mycologic effects than any other group of medications used in this study. Steroid acne and other acneiform eruptions showing discrete follicular papules and/or pustules localized to the upper trunk and acneiform facial skin lesions associated with multiple acneiform lesions on the body in the summer period should be suspected as Pityrosporum folliculitis. In addition, oral antifungal drugs recommended for Pityrosporum folliculitis; however, it will require a larger case-control study to confirm the superiority of antifungal therapy over anti-acne treatment.

Remote sensing data fusion has been playing a more and more important role in crop planting area monitoring, especially for crop area information acquisition. Multi-temporal data and multi-spectral time series are two major aspects for improving crop identification accuracy. Remote sensing fusion provides high quality multi-spectral and panchromatic images in terms of spectral and spatial information, respectively. In this paper, we take one step further and prove the application of remote sensing data fusion in detecting illicit crop through LSMM, GOBIA, and MCE analyzing of strategic information. This methodology emerges as a complementary and effective strategy to control and eradicate illicit crops.

In response to recent incidents of undeclared sibutramine, an appetite suppressant found in dietary supplements, we developed a method to detect sibutramine using hand-held ion mobility spectrometers with an analysis time of 15 s. Ion mobility spectrometry is a high-throughput and sensitive technique that has been used for illicit drug, explosive, volatile organic compound and chemical warfare detection. We evaluated a hand-held ion mobility spectrometer as a tool for the analysis of supplement extracts containing sibutramine. The overall instrumental limit of detection of five portable ion mobility spectrometers was 2 ng of sibutramine HCl. When sample extractions containing 30 ng/μl or greater of sibutramine were analyzed, saturation of the ionization chamber of the spectrometer occurred and the instrument required more than three cleaning cycles to remove the drug. Hence, supplement samples suspected of containing sibutramine should be prepared at concentrations of 2-20 ng/μl. To obtain this target concentration range for products containing unknown amounts of sibutramine, we provided a simple sample preparation procedure, allowing the U.S. Food and Drug Administration or other agencies to screen products using the portable ion mobility spectrometer.

Cluster headache (CH) patients often receive unsatisfactory treatment and may explore illicit substances as alternatives. We aimed to explore this use of illicit drugs for CH treatment. We invited CH patients from an Internet-based self-help group to complete a questionnaire regarding their therapeutic use of illicit substances. Of the 54 respondents, 29 were classified as chronic and 39 were drug-resistant cases. Fifty patients had previously tried subcutaneous sumatriptan, 40 had tried O2, and 48 had tried at least one prophylactic treatment. All 54 patients specified that they were dissatisfied with conventional treatments. Thirty-four patients had used cannabinoids, 13 cocaine, 8 heroin, 18 psilocybin, 12 lysergic acid amide (LSA), and 4 lysergic acid diethylamide (LSD). Some patients with intractable CH decided to try illicit drugs concomitantly with cessation of medical care. Most of these patients found suggestions for illicit drug use on the Internet. Many patients seemed to underestimate the judicial consequences of, and had an overestimated confidence in the safety of, such illicit treatments. Physicians are often not informed by patients of their choice to use illicit drugs. This leads to questions regarding the true nature of the physician-patient relationship among dissatisfied CH patients. © International Headache Society 2015.

Prevention of the inadvertent movement and illicit trafficking of radioactive materials

International Nuclear Information System (INIS)

2004-05-01

By international agreements, the movement of all radioactive materials within and between States should be subject to high standards of regulatory, administrative, safety and engineering controls to ensure that such movements are conducted in a safe and secure manner. In the case of nuclear materials, there are additional requirements for physical protection and accountability to ensure against threats of nuclear proliferation and to safeguard against any attempts at diversion. The results of the terrorist attacks of September 2001 emphasized the requirement for enhanced control and security of nuclear and radioactive materials. In this regard, measures are being taken to increase the global levels of physical protection and security for nuclear materials. Experience in many parts of the world continues to prove that movements of radioactive materials outside of the regulatory and legal frameworks continue to occur. Such movements may be either deliberate or inadvertent. Deliberate, illegal movements of radioactive materials, including nuclear material, for terrorist, political or illegal profit is generally understood to be illicit trafficking. The more common movements outside of regulatory control are inadvertent in nature. An example of an inadvertent movement might be the transport of steel contaminated by a melted radioactive source that was lost from proper controls. Such a shipment may present health and safety threats to the personnel involved as well as to the general public. States have the responsibility for combating illicit trafficking and inadvertent movements of radioactive materials. The IAEA co-operates with Member States and other international organizations in joint efforts to prevent incidents of illicit trafficking and inadvertent movements and to harmonize policies and measures by the provision of relevant advice through technical assistance and documents.

2004-08-01

This issue of IJSNEM features two articles related to supplement use by athletes. In one (Morrison et al. 2004), people who undertake regular exercise in a gym were found to report the use of a wide variety of supplements. The other paper (Goel et al. 2004) dealt with one of the issues that a sub-group of athletes need to consider before deciding to take supplements - the risk of a positive drug test if the product contains substances banned by the anti-doping codes under which their sport is conducted. This issue received much publicity earlier in the year when top tennis player Greg Rusedski tested positive for the steroid nandrolone as the result of inadvertent intake via a contaminated supplement. In this article, Professor Ron Maughan, Chair of Sports Nutrition at Loughborough University in the United Kingdom, advisor to the British Olympic team, and co-editor of IJSNEM, provides his insight on this important topic.

To present the interpreted experiences of midwives who choose to work with pregnant women who also use illicit drugs. Twelve (n=12) Australian midwives were interviewed. Each interview was audio-taped, de-identified and transcribed. The interviews were analysed using a systematic, thematic analysis approach informed by Heideggarian hermeneutic phenomenology. Three themes identified from the data that encapsulate the experience were establishing partnerships, making a difference, and letting go and redefining practice. The interpretations of establishing partnerships which includes engagement, genuine regard and compassion, with a subtheme courting the system are presented in this paper. The midwives' experiences were both positive and negative, as they were rewarded and challenged by the needs of women who use illicit drugs and the systems in which they worked. The midwives in this study found that establishing partnerships was essential to their work. They appraised their experience of working with pregnant women who used illicit drugs and found strategies that attempted to meet the needs of the women, the system and themselves. The participants revealed that to support women and families who use illicit drugs in their community, partnerships must be based on deep respect and trust. Significant components engagement, genuine regard and compassion that are central to midwifery partnerships require revisiting to address the needs of this vulnerable population of women.

2011-01-01

Levels of cocaine and other psychoactive substances in atmospheric particulate matter (PM) were determined in urban environments representing distinct social behaviours with regard to drug abuse: night-life, university and residential areas. Three cities (with population >1 million and 3 for cocaine, 23-34 pg/m 3 for cannabinoids, and 5-90 pg/m 3 for heroin. The highest levels were recorded on weekends, with factors with respect to weekdays of 1-3 for cocaine, 1-2 for cannabinoids and 1.1-1.7 for heroin. Higher levels were detected in the night-life areas, pointing towards consumption and trafficking as major emission sources, and possibly ruling out drug manufacture. The similarities in temporal trends at all sites suggested a city-scale transport of psychoactive substances. Correlations were detected between cocaine and amphetamine consumption (r 2 = 0.98), and between heroin and cannabinoids (r 2 >0.82). - Highlights: → Cocaine, heroin, cannabis and related illicit drugs are found in detectable amounts in urban air. → Illicit drug consumption and small-scale trafficking are the major emission sources. → Illicit drugs remain in atmospheric particles and are transported across cities during at least 5 days. → Levels of illicit drugs increase from residential to night-life areas, and maximise on weekends. → Correlations between illicit drugs were detected, suggesting differences in consumer groups. - The presence of illicit drugs in atmospheric particles can be used to track illicit drug abuse.

However, several cardiovascular complications including hypertension, cardiomyopathy, stroke, pulmonary embolism, fatal and nonfatal arrhythmias, and myocardial infarction have been reported with supraphysiologic doses of anabolic steroids. We report a case of an acute ST-segment elevation myocardial infarction in a patient with traditional cardiac risk factors using supraphysiologic doses of supplemental, intramuscular testosterone. In addition, this patient also had polycythemia, likely secondary to high-dose testosterone. The patient underwent successful percutaneous intervention of the right coronary artery. Phlebotomy was used to treat the polycythemia acutely. We suggest that the chronic and recent “stacked” use of intramuscular testosterone as well as the resultant polycythemia and likely increased plasma viscosity may have been contributing factors to this cardiovascular event, in addition to traditional coronary risk factors. Physicians and patients should be aware of the clinical consequences of anabolic steroid abuse.Keywords: acute myocardial infarction, anabolic steroid use, polycythemia

The relevance of this problem in general and peculiar features of its research in developing economies are substantiated. The experience of organizations created to prevent the legalization of illicit funds is studied. It is determined that new organizations are created in response to the global challenges. It is justified that in Ukraine the fight against the legalization of illicit funds has actualized due to a lack of financial resources in the country, declaration of course towards European values and also as a result of the military conflict in the east of the country. The risk factors for financial fraud and illegal movement of financial flows are systematized according to the groups of conditions: pressure, favorable situation, propensity (justification. It is determined which levels of risk of generating illegal financial flows are inherent in different sectors of the economy depending on institutional factors. It is argued that the increase in the risks of illegal financial flows occurs under conditions of a low level of maturity of the institutional environment and a high level of information asymmetry. Types and tools of fraud in the financial market that increase the risks of illegal financial flows are systematized. It is determined that main types of fraud in the financial market are related to information manipulations and regulatory deficiencies. The world experience of legislative initiatives on counteracting the legalization of funds in financial markets is systematized. It is justified that, in order to prevent financial fraud and prevent legalization of illicit funds in Ukraine, it is necessary to ensure maximum transparency of information on the movement of financial flows in financial markets. In addition, regulators of the financial market should not only cooperate with each other but also prevent

Full Text Available Africa is facing a number of challenges that are negatively affecting socio-economic development at all levels of governments and local governments are expected to play a leading role for Africa’s development. One of these challenges are illicit financial flows that are perceived by many as a crime against Africa’s transformation. The continent is losing billions of dollars every year because of tax evasion, corruption and inappropriate transfer pricing and maladministration. With tax being one of Africa’s main sources of revenue, current and past researches revealed that, illicit financial flows (IFFs cripple African Governments tax base as a results of capital outflows and lack of good governance. This situation obviously is a challenge for Africa’s development as governments struggle to finance structuring projects and this in turn compels these governments to seek funds from international organisations at very high interest rates. It is also important to reveal that Foreign Direct Investment (FDI rapidly grew after the Second World War with the intention to maximize profit on investment in less developed countries and specifically in the African continent. In competing in Africa, most multinationals main objective is to pay less tax, make extensive profits and transfer the proceeds to their country of origin. This subsequently gave rise to illicit financial flows in Africa where the continent is losing billions of dollars. Past studies equally revealed that, Africa’s revenue could increase between 55 and 65%, if appropriate mechanisms of monitoring the flows were in place. This study therefore is based on the premise that, tax evasion, illicit financial flows, corruption and abusive transfers pricing are all factors that affect Africa’s development. Using appropriate method of inquiry, this study wants to demonstrate the presence of FDI’s in Africa as a modus operandi behind tax evasion. It also using the �

Alternative antisera against 17 α-methyltestosterone and 19-nortestosterone were raised and used for radioimmunoassay of anabolic steroids. Tritiated compounds were used as radioligands. The RIA method suitable for doping control is proposed for 17 α-alkylated anabolic steroids in both plasma and urine, using qoat antiserum against methyltestosterone-3-carboxymethyloxime-BSA. Sensitivity of the method was expressed as least amount of nonradioactive methandienone which, when added to normal urine or plasma, caused statistically significant decrease of measured supernatant radioactivity at 99% level. The amounts from 50 to 500 pg were tested, each in eight parallel determinations. The amounts of 100 pg for plasma and 200 pg for urine met these criteria. The respective coefficients of variation did not depend on the amount of steroid added in this range. They averaged 4.60% for plasma and 4.95% for urine, respectively. (T.I.)

Chronic anabolic steroid use suppresses left ventricular functions. However, there is no information regarding the chronic effects of anabolic steroids on right ventricular function which also plays a key role in global cardiac function. The main objective of the present study was to investigate the effects of androgenic anabolic steroids usage among athletes on remodeling the right part of the heart. Androgenic-anabolic steroids-using bodybuilders had smaller diastolic velocities of both ventricles than drug-free bodybuilders and sedentary counterparts. This study shows that androgenic anabolic steroids-using bodybuilders exhibited depressed diastolic functions of both ventricles.

2009-01-01

This cross-sectional multi-centre study explored how family members and friends of illicit drug users perceived protective and risk factors, treatment facilities and policies and laws regarding illicit drug use. Family members and friends of illicit drug users were recruited in 10 urban health care outpatient units in 7 Latin American countries (Brazil, Colombia, Costa Rica, Ecuador, Guatemala, Honduras and Mexico) to complete a questionnaire. The majority of the respondents chose psycho-social factors over genetic or biological explanations as causes of drug problems. Respondents felt that families and governments were responsible for preventing drug problems. Church/religious institutions were most often mentioned in the context of accessible treatment. When asked about access to treatment facilities, the majority said that there were not enough. Shame about drug use, cost, and limited treatment options were most often cited as barriers to treatment.

Mitochondrial benzodiazepine receptors regulate steroid biosynthesis

International Nuclear Information System (INIS)

Mukhin, A.G.; Papadopoulos, V.; Costa, E.; Krueger, K.E.

1989-01-01

Recent observations on the steroid synthetic capability within the brain open the possibility that benzodiazepines may influence steroid synthesis in nervous tissue through interactions with peripheral-type benzodiazepine recognition sites, which are highly expressed in steroidogenic cells and associated with the outer mitochondrial membrane. To examine this possibility nine molecules that exhibit a greater than 10,000-fold difference in their affinities for peripheral-type benzodiazepine binding sites were tested for their effects on a well-established steroidogenic model system, the Y-1 mouse adrenal tumor cell line. 4'-Chlorodiazepam, PK 11195, and PK 14067 stimulated steroid production by 2-fold in Y-1 cells, whereas diazepam, flunitrazepam, zolpidem, and PK 14068 displayed a lower (1.2- to 1.5-fold) maximal stimulation. In contrast, clonazepam and flumazenil did not stimulate steroid synthesis. The potencies of these compounds to inhibit 3 H-labeled PK 11195 binding to peripheral-type benzodiazepine recognition sites correlated with their potencies to stimulate steroid production. Similar findings were observed in bovine and rat adrenocortical cell preparations. These results suggest that ligands of the peripheral-type benzodiazepine recognition site acting on this mitochondrial receptor can enhance steroid production. This action may contribute specificity to the pharmacological profile of drugs preferentially acting on the benzodiazepine recognition site associated with the outer membrane of certain mitochondrial populations

Full Text Available Background Children with nephrotic syndrome need high-dose corticosteroids to achieve remission. Studies have estimated a 35-43% risk of obesity in these patients after corticosteroid treatment. Objective To determine the prevalence of obesity in children who received corticosteroids for nephrotic syndrome, and to compare the risk of obesity in children with steroid-sensitive nephrotic syndrome (SSNS and steroid-resistant nephrotic syndrome (SRNS. Methods We performed a retrospective cohort study in 50 children with SSNS or SRNS who received corticosteroid treatment. Obesity was defined to be a BMI-for-age Z-score above +2.0 SD, according to the WHO Growth Reference 2007. Central obesity was defined to be a waist-to-height ratio > 0.50. Results The overall prevalence of obesity was 22%, with 29% and 14% in the SSNS and SRNS groups, respectively. The overall prevalence of central obesity was 50%, with 54% and 46% in the SSNS and SRNS groups, respectively. The cumulative steroid doses in this study were not significantly different between the SSNS and SRNS groups. There were also no significant differences between groups for risk of obesity (RR 2.53; 95%CI 0.58 to 10.99 or central obesity (RR 1.39; 95%CI 0.45 to 4.25. Conclusion In children with nephrotic syndrome who received corticosteroids, the prevalence of obesity is 22% and of central obesity is 50%. In a comparison of SSNS and SRNS groups, cumulative steroid dose as well as risks of obesity and central obesity do not significantly differ between groups.

Getting More Than You Paid For: Unauthorized "Natural" Substances in Herbal Food Supplements on EU Market.

2018-04-01

As the population in the industrialized world develops preference for what is perceived as a natural and holistic way of disease treatment, the popularity and the number of food supplements on the market, including herbal ones, is experiencing an unprecedented rise. However, unlike herbal medicinal products, intended for treating or preventing disease, current legislation classifies food supplements as products intended for achieving nutritional or physiological effect and to supplement the normal diet. Accordingly, most food supplements are not to be associated with specific health claims. However, either due to the subtle suggestions by the producers or the wishful thinking of the consumers, certain pharmacological effects from food supplements are often expected. Medicinal plants included in food supplements usually do not produce dramatic and instant pharmacological effects. Therefore, in order to meet the expectation of their customers, some producers have turned to the illicit and dangerous practice of adulterating their products with synthetic adulterants, including naturally occurring molecules, having the desired activity. Such practice is prevalent in, although not limited to, food supplements intended for use as weight-loss aids, as well as for sport performance and libido enhancement. The review is focusing on naturally occurring alkaloids, phenylethanolamines, and their semi-synthetic derivatives in food supplements in the European Union as reported by the Rapid Alert System for Food and Feed. Their desired and undesired pharmacological effects, as well as the methods for their detection and quantification in food supplements, will be reviewed. Georg Thieme Verlag KG Stuttgart · New York.

There is limited empirical integration between peer clustering theory and the Gateway framework. The goal of the present study was to test the hypothesis that friendship associations partly predict gateway escalations in the use of drugs from adolescence to adulthood. This longitudinal study analyzed 3 waves of data from a community sample of 711 male and female participants without a history of illicit drug use reporting drug use at age 17, 22, and 27. Substance use assessments including tobacco, alcohol, cannabis, onset and abuse/dependence tendency of illicit drugs other than cannabis (i.e., cocaine, methamphetamine, and opiates), and friends' reported use of illicit drugs. Structural equation modeling was used to test the hypothesized model. Participants' cannabis use level at age 17 was positively associated with perceived friends' drug use at age 22, which in turn predicted participants' onset of illicit drug use between ages 22 and 27. Moreover, progression of tobacco use throughout age 17 to 22 was associated with an increased onset of illicit drug use between ages 22 and 27. Apart for an effect of cannabis use at age 22 on abuse and dependence tendency to various drugs at age 28, results were similar. During this period of development, the availability and selection of drug-using friends contributes to the progression to potentially more rewarding and damaging illicit drugs. These findings suggest the need to attend to the peer ecology in prevention and support the common practice of using abstaining peers in treatment for drug dependence. Copyright © 2017.

Physical protection as the most important part of the national system of combating illicit trafficking

Ivanov, P.; Kokhan, V.D.

It is obvious today that illicit trafficking, including its most dangerous manifestations proliferation of nuclear weapons, smuggling of nuclear materials and equipment, presents a serious threat to the international community. To defeat this evil is possible only by joint efforts, by undertaken protective measures on national and international levels. Joint efforts should be directed at fulfilling three main tasks as follows: 1. Safe and reliable handling of nuclear material, effective measures of its physical protection, accountancy and control in order to prevent proliferation; 2. Joint activities of intelligence customs and law-enforcement authorities directed at prevention of international trafficking and marketing of stolen goods; 3. Joint activities directed at identification and prevention of illegal supply and demand of fissionable materials counteracting thereby various criminal structures. We believe that in order to solve these problems an international regime should be established. Such an international regime will make the states implement the existing international agreements that will strengthen their postings regarding non-proliferation of nuclear weapons, ensure combating of illicit trafficking as well as facilitating cooperation between national and international databases on non-proliferation of nuclear weapons, bilateral agreements between state authorities and international organizations regarding joint investigation procedures of the cases involving illicit trafficking. We believe that these goals of an international regime against illicit trafficking can be achieved by only one organization - the IAEA, an authority respected by the international community and presently responsible for nuclear safeguards. Recommendations and guidelines on physical protection, including the Convection on Physical Protection, have been developed under its auspices. The IAEA enjoys great respect and has extensive contacts including those with Interpol; it

Membrane receptors are often modulated by steroids and it is necessary to distinguish the effects of steroids at these receptors from effects occurring at nuclear receptors. Additionally, it may also be mechanistically important to distinguish between direct effects caused by binding of steroids to membrane receptors and indirect effects on membrane receptor function caused by steroid perturbation of the membrane containing the receptor. In this regard, ent-steroids, the mirror images of natu...

Beyond T and DHT - novel steroid derivatives capable of wild type androgen receptor activation.

Science.gov (United States)

Mostaghel, Elahe A

2014-01-01

While androgen deprivation therapy (ADT) remains the primary treatment for metastatic prostate cancer (PCa), castration does not eliminate androgens from the prostate tumor microenvironment, and residual intratumoral androgens are implicated in nearly every mechanism by which androgen receptor (AR)-mediated signaling promotes castration-resistant disease. The uptake and intratumoral (intracrine) conversion of circulating adrenal androgens such as dehydroepiandrosterone sulfate (DHEA-S) to steroids capable of activating the wild type AR is a recognized driver of castration resistant prostate cancer (CRPC). However, less well-characterized adrenal steroids, including 11-deoxcorticosterone (DOC) and 11beta-hydroxyandrostenedione (11OH-AED) may also play a previously unrecognized role in promoting AR activation. In particular, recent data demonstrate that the 5α-reduced metabolites of DOC and 11OH-AED are activators of the wild type AR. Given the well-recognized presence of SRD5A activity in CRPC tissue, these observations suggest that in the low androgen environment of CRPC, alternative sources of 5α-reduced ligands may supplement AR activation normally mediated by the canonical 5α-reduced agonist, 5α-DHT. Herein we review the emerging data that suggests a role for these alternative steroids of adrenal origin in activating the AR, and discuss the enzymatic pathways and novel downstream metabolites mediating these effects. We conclude by discussing the potential implications of these findings for CRPC progression, particularly in context of new agents such as abiraterone and enzalutamide which target the AR-axis for prostate cancer therapy.

Experiences with lesbian, gay, bisexual, transgender, or queer (LGBTQ) discrimination and racism have both been associated with mental health problems and illicit drug use. However, the cumulative effects of both forms of discrimination--and resulting internalized oppression--on illicit drug use in LGBTQ people of color (POC) has not been examined in the research literature. Using online questionnaires, this study collected self-report data from 200 LGBTQ POC about their experiences with racism, LGBTQ discrimination, internalized racism, internalized LGBTQ discrimination, and illicit drug use. Two structural equation models yielded adequate fit indices in which experiences with racism and LGBTQ discrimination led to more internalized oppression, which then led to greater illicit drug use magnitude. LGBTQ discrimination was directly related to increased internalized oppression, which was positively associated with illicit drug use magnitude; the relationship between LGBTQ discrimination and illicit drug use magnitude was mediated by internalized oppression in both models. However, racism and the interaction between racism and LGBTQ discrimination did not show valid direct effects on internalized oppression or indirect effects on illicit drug use magnitude. LGBTQ POC can be the targets of both racism and LGBTQ discrimination, although the current study found that the most psychologically damaging effects may come from LGBTQ discrimination. Interventions meant to decrease or prevent illicit drug use in LGBTQ POC may benefit from helping participants examine the links among LGBTQ discrimination, internalized oppression, and illicit drug use as a coping strategy, focusing on substituting more adaptive coping.

To estimate and compare price differences between legal and illicit cigarettes in 14 low- and middle-income countries (LMIC). A cross-sectional census of all packs available on the market was purchased. Cigarette packs were purchased in formal retail settings in three major cities in each of 14 LMIC: Bangladesh, Brazil, China, Egypt, India, Indonesia, Mexico, Pakistan, the Philippines, Russia, Thailand, Turkey, Ukraine and Vietnam. A total of 3240 packs were purchased (range = 58 packs in Egypt to 505 in Russia). Packs were categorized as 'legal' or 'illicit' based on the presence of a health warning label from the country of purchase and existence of a tax stamp; 2468 legal and 772 illicit packs were in the analysis. Descriptive statistics stratified by country, city and neighborhood socio-economic status were used to explore the association between price and legal status of cigarettes. The number of illicit cigarettes in the sample setting was small (n price of legal cigarettes ranged from US$0.32 in Pakistan (n = 72) to US$3.24 in Turkey (n = 242); median purchase price of illicit cigarettes ranged from US$0.80 in Ukraine (n = 14) to US$3.08 in India (n = 41). The difference in median price between legal and illicit packs as a percentage of the price of legal packs ranged from 32% in Philippines to 455% in Bangladesh. Median purchase price of illicit cigarette packs was higher than that of legal cigarette packs in six countries (Bangladesh, India, Pakistan, Philippines, Thailand, Vietnam). Median purchase price of illicit packs was lower than that of legal packs in Turkey, Ukraine and China. The median purchase price of illicit cigarettes is higher than that of legal cigarette packs in Bangladesh, India, Pakistan, Philippines, Thailand, and Vietnam, Brazil, Egypt, Indonesia, Mexico, Russia appear to have few or no illicit cigarettes for purchase from formal, urban retailers. © 2017 The Authors.

Levels of cocaine and other psychoactive substances in atmospheric particulate matter (PM) were determined in urban environments representing distinct social behaviours with regard to drug abuse: night-life, university and residential areas. Three cities (with population >1 million and <0.3 million inhabitants) were selected. Mean daily levels of drugs in PM were 11-336 pg/m{sup 3} for cocaine, 23-34 pg/m{sup 3} for cannabinoids, and 5-90 pg/m{sup 3} for heroin. The highest levels were recorded on weekends, with factors with respect to weekdays of 1-3 for cocaine, 1-2 for cannabinoids and 1.1-1.7 for heroin. Higher levels were detected in the night-life areas, pointing towards consumption and trafficking as major emission sources, and possibly ruling out drug manufacture. The similarities in temporal trends at all sites suggested a city-scale transport of psychoactive substances. Correlations were detected between cocaine and amphetamine consumption (r{sup 2} = 0.98), and between heroin and cannabinoids (r{sup 2}>0.82). - Highlights: > Cocaine, heroin, cannabis and related illicit drugs are found in detectable amounts in urban air. > Illicit drug consumption and small-scale trafficking are the major emission sources. > Illicit drugs remain in atmospheric particles and are transported across cities during at least 5 days. > Levels of illicit drugs increase from residential to night-life areas, and maximise on weekends. > Correlations between illicit drugs were detected, suggesting differences in consumer groups. - The presence of illicit drugs in atmospheric particles can be used to track illicit drug abuse.

Due to the alarming rise in opioid-related overdose deaths, a public health emergency was declared in British Columbia (BC). In this study, we examined the relationship between illicit fentanyl and heroin found in seized drugs and illicit overdose deaths in BC. An observational cross-sectional survey was conducted using BC data from Health Canada's Drug Analysis Service, which analyzes drug samples seized by law enforcement agencies, and non-intentional illicit overdoses from the BC Coroner's Service, from 2000 to 2016. Initial scatter plots and subsequent multivariate regression analysis were performed to describe the potential relationship between seized illicit fentanyl samples and overdose deaths and to determine if this differed from seized heroin and overdose deaths. Fentanyl samples were analyzed for other drug content. Fentanyl is increasingly being found combined with other opioid and non-opioid illicit drugs. Strong positive relationships were found between the number of seized fentanyl samples and total overdose deaths (R2 = 0.97) as well as between seized fentanyl and fentanyl-detected overdose deaths (R2 = 0.99). A positive association was found between the number of seized heroin samples and total overdose deaths (R2 = 0.78). This research contributes to the expanding body of evidence implicating illicit fentanyl use (often combined with heroin or other substances) in overdose deaths in BC. Policy makers and healthcare providers are urged to implement drug treatment and harm reduction strategies for people at risk of overdose associated with current trends in illicit opioid use.

Non-medical use of prescription drugs (NMUPD) is known to be associated with illicit drug use, but less is known about how illicit drug use has changed in NMUPD. We examined (1) the changes in illicit drug use among Finnish non-medical users of prescription drugs during the 2000s and (2) whether the trends of illicit drug use differ by non-medical use of prescription drugs in the general population. Data were derived from population-based (aged 15-69) Drug Surveys conducted in Finland in 2002, 2006, 2010 and 2014. The response rates varied between 63% and 48%. NMUPD during the last year was measured (n=252). Past-year illicit drug use among non-medical users of prescription drugs and the reference population not reporting NMUPD (n=10,967) was compared. Logistic regression was used to estimate the p-values for trends. Illicit drug use has increased notably among Finnish non-medical users of prescription drugs (from 21% to 70%, p for trendillicit drug use also increased statistically significantly, but much more moderately (from 2.5% to 5.4%). The difference between the trends was confirmed by an interaction test (p=0.022). NMUPD seems to be increasingly merging with illicit drug use. This indicates an increasing prevalence of polydrug use among non-medical users of prescription drugs, which may bring about more severe harms and worse health outcomes for users and more challenges in regard to treatment.

When undertaking these measures one should take into account specific characteristics of the state, its unique features and its geography, political and economic situation, as well as different types of potential threat of proliferation of nuclear weapons; availability of materials subjected to illicit trafficking in this state, general situation of criminal trafficking in this state, general situation of criminal trafficking with radioactive materials, potential consumers and suppliers, market features, possible incentives for crime etc. In the paper I would like to reflect the vital components of national systems for combating

Illicit liquors are illegally manufactured to evade taxes and represent the majority of unrecorded liquors in developing countries. Because there are no standards, the composition of illicit liquors varies greatly from sample to sample. In the current study, we analyzed the volatile components of 27 different illicit liquors via samples collected from various locations in the northern region of India. Ethanol content varied drastically and methanol was not present in any of the samples. The components found can be categorized into different groups, namely alcohols, esters, acids, nitrogen-containing components, ketones, and aldehydes. Some components-such as 1-propanol; 1-pentanol; 1-butanol; d-limonene; phenylethyl alcohols; anethole; and decanoic, octanoic, and pentanoic acids-were frequently encountered.

The objective of this study was to investigate the association between adverse childhood experiences (ACEs) and the use of alcohol, tobacco and illicit drugs among adolescents from a Brazilian cohort. The occurrence of five ACEs, the use of alcohol and tobacco and trying illicit drugs were investigated in the 1993 Pelotas birth cohort at the age of 15 (n = 4,230). A score was created for the ACEs and their association with the use of substances was evaluated. Around 25% of adolescents consumed alcohol, 6% smoked and 2.1% reported having used drugs at least once in their lives. The ACEs were associated with the use of alcohol, tobacco and illicit drugs. A dose-response relation between the number of ACEs and the substance use was found, particularly with regard to illicit drugs. The occurrence of ACEs was positively associated with the use of alcohol, tobacco and illicit drugs among adolescents and the risk may be different for men and women. These results point to the fact that strategies for preventing the use of substances should include interventions both among adolescents and within the family environment.

1983-01-01

Freshly ejaculated spermatozoa from monkey and human were washed and incubated with tritium labelled androgens or estradiol to study the pattern of spermatozoa steroid metabolism. When equal concentrations of steroid substrates were used for incubation, monkey and human spermatozoa showed very similar pattern of steroid conversion. Spermatozoa from both species converted testosterone mainly to androstenedione, but reverse conversion of androstenedione to testosterone was negligible. Estradiol-17 beta was converted mainly to estrone. The close similarity between the spermatozoa of monkey and men in their steroid metabolic pattern indicates that the rhesus monkey could be an useful animal model to study the effect of drugs on the metabolic pattern of human spermatozoa

STEROIDS MOST OFTEN USED BY SPORTSMEN

Full Text Available Abusage of steroids can cause serious health problems some of which are incurable, such as liver cancer. They cause a series of other effects: pimples, hairiness, boldness, gynecomastness, headaches, impotence, problems with heart and kidney functions. In addition to physical disorders, there are psychological problems too, such as aggression, depression and even addiction. Why do sportsmen abuse steroids? The main reason is to improve results in sports competitions. Others do that in order to increase muscular mass and decrease fat tissue. So you should decide for yourselves – steroids or health?

The catalytic substitution of bromine for tritium in corresponding bromo-derivatives of steroids was used for the preparation of 4 steroids labelled with tritium at position 7. The bromination of the starting steroids was effected with N-bromosuccinimide. Ten steroids labelled with tritium at the positions 1, 2, 6 and 7 were prepared by reduction of the unsaturated derivatives with gaseous tritium in the presence of either the heterogeneous Pd/C catalyst, or the homogeneous chloride of tris(triphenylphosphine)rhodium

2013-12-01

The use of anabolic androgenic steroids has not been traditionally discussed in mainstream medicine. With the increased diagnosis of hypogonadism a heterogeneous population of men is now being evaluated. In this larger patient population the existence of anabolic steroid induced hypogonadism, whether transient or permanent, should now be considered. We performed an initial retrospective database analysis of all 6,033 patients who sought treatment for hypogonadism from 2005 to 2010. An anonymous survey was subsequently distributed in 2012 to established patients undergoing testosterone replacement therapy. Profound hypogonadism, defined as testosterone 50 ng/dl or less, was identified in 97 men (1.6%) in the large retrospective cohort initially reviewed. The most common etiology was prior anabolic androgenic steroid exposure, which was identified in 42 men (43%). Because of this surprising data, we performed an anonymous followup survey of our current hypogonadal population of 382 men with a mean±SD age of 49.2±13.0 years. This identified 80 patients (20.9%) with a mean age of 40.4±8.4 years who had prior anabolic androgenic steroid exposure. Hypogonadal men younger than 50 years were greater than 10 times more likely to have prior anabolic androgenic steroid exposure than men older than 50 years (OR 10.16, 95% CI 4.90-21.08). Prior anabolic androgenic steroid use significantly correlated negatively with education level (ρ=-0.160, p=0.002) and number of children (ρ=-0.281, panabolic androgenic steroid use is common in young men who seek treatment for symptomatic hypogonadism and anabolic steroid induced hypogonadism is the most common etiology of profound hypogonadism. These findings suggest that it is necessary to refocus the approach to evaluation and treatment paradigms in young hypogonadal men.

To estimate the prevalence of illicit drug use and its association with binge drinking and sociodemographic factors among adolescent students. This is a cross-sectional study with probabilistic conglomerate sampling, involving 1,154 students, aged 13 to 19 years old, from the public school system, in the city of Olinda, State of Pernambuco, Brazil, carried out in 2014. We used the Youth Risk Behavior Survey questionnaire, validated for use with Brazilian adolescents. The Chi-square test (≤ 0.05) and Poisson regression analysis were used to estimate the prevalence ratios, with 95% confidence intervals. Use in life of illicit drugs was four times more prevalent among students who reported binge drinking (95%CI 3.19-5.45). Being in the age group of 16 to 19 years, being male, and having no religion were also significantly associated with illicit drug use. The prevalence of use in life of illicit drugs was higher in this study than in other studies carried out in Brazil and it was strongly associated with binge drinking. This factor was associated with gender, age, and religion.

Para análise dos dados foi utilizado o teste do Qui-quadrado (≤ 0,05) e análise de regressão de Poisson, para estimar razões de prevalência, com intervalos com 95% de confiança. O uso na vida de drogas ilícitas foi quatro vezes mais prevalente entre os estudantes que relataram o binge drinking (IC95% 3,19-5,45). Estar na faixa etária de 16 a 19 anos, ser do sexo masculino e não ter religião também foram significativamente associados ao uso de drogas

How do Australian news media depict illicit drug issues? An analysis of print media reporting across and between illicit drugs, 2003-2008.

Media reporting on illicit issues has been frequently criticised for being sensationalised, biased and narrow. Yet, there have been few broad and systematic analyses of the nature of reporting. Using a large sample and methods commonly adopted in media communications analysis this paper sought to identify the dominant media portrayals used to denote illicit drugs in Australian newspapers and to compare and contrast portrayals across drug types. A retrospective content analysis of Australian print media was carried out over the period 2003-2008 from a sample comprised of 11 newspapers. Articles that contained one or more mention of five different drugs (or derivatives) were identified: cannabis, amphetamines, ecstasy, cocaine and heroin. A sub-sample of 4397 articles was selected for media content analysis (with 2045 selected for full content analysis) and a large number of text elements coded for each. Key elements included topic, explicit or implicit messages about the consequences of drugs/use and three value dimensions: overall tone, whether drugs were portrayed as a crisis issue and moral evaluations of drugs/use. The dominant media portrayals depicted law enforcement or criminal justice action (55%), but most articles were reported in a neutral manner, in the absence of crisis framings. Portrayals differed between drugs, with some containing more narrow frames and more explicit moral evaluations than others. For example, heroin was disproportionately framed as a drug that will lead to legal problems. In contrast, ecstasy and cocaine were much more likely to emphasise health and social problems. Media reporting on illicit drugs is heavily distorted towards crime and deviance framings, but may be less overtly sensationalised, biased and narrowly framed than previously suggested. This is not to suggest there is no sensationalism or imbalance, but this appears more associated with particular drug types and episodes of heightened public concern. Copyright © 2011

The influence of sex steroids on pineal enzymes

International Nuclear Information System (INIS)

Daya, S.

1982-01-01

The influence of the gonadal sex steroids namely, estradiol, progesterone and testosterone on the two major enzymes responsible for the synthesis of melatonin in the pineal gland was investigated. These enzymes are Serotonin-N-acetyltransferase (SNAT) and Hydroxyindole-O-methyltransferase (H10MT). Testosterone was found to be the only sex steroid capable of influencing SNAT activity whereas all three of the sex steroids were found to influence H10MT activity in a biphasic dose-dependent manner. The influence of these sex steroids on radiolabelled serotonin metabolism by pineals in organ culture was also investigated. Ovariectomy, castration and the sex steroids were all found to alter the pattern of the radiolabelled serotonin metabolism by these pineal glands in organ culture

We report the results of an experimental study of the sensitivity of two distinct classes of systems that exploit nuclear resonance fluorescence (NRF) to search for illicit materials in containers. One class of systems is based on the direct detection of NRF photons emitted from isotopes of interest. The other class infers the presence of a particular isotope by observing the preferential attenuation of resonant photons in the incident beam. We developed a detailed analytical model for both approaches. We performed experiments to test the model using depleted uranium as a surrogate for illicit material and used tungsten as a random choice for shielding. We performed the experiments at Duke University's High Intensity Gamma Source (HIGS). Using the methodology we detail in this paper one can use this model to estimate the performance of potential inspection systems in certifying containers as free of illicit materials and for detecting the presence of those same materials.

This study analyzes the prevalence of illicit drug use and associated factors during pregnancy. This was a cross-sectional study of participants in the BRISA prenatal care cohort. Frequencies and hierarchical logistic regression were used. Estimated prevalence rates were 1.45% for illicit drug use, 22.32% for alcohol consumption, and 4.22% for smoking. The study population was mostly young (81% in the 20-34-year bracket), with 9 to 11 years of schooling (75.55%), with more than half of the women outside the workforce (52.18%), and in economic class "C" (67.61%). Pregnant women showed a high level of stress (24.46%), moderate to intense anxiety (40.84%), and severe depressive symptoms (28.8%). Approximately half (49.72%) of the pregnant women reported some type of violence, and they had wide networks (72.77%) and low social support (65.21%). Use of legal drugs, high stress levels, and single parenthood were independently associated with illicit drug use in pregnancy.

Anabolic steroids for treating pressure ulcers.

Naing, Cho; Whittaker, Maxine A

2017-06-20

Pressure ulcers, also known as bed sores, pressure sores or decubitus ulcers develop as a result of a localised injury to the skin or underlying tissue, or both. The ulcers usually arise over a bony prominence, and are recognised as a common medical problem affecting people confined to a bed or wheelchair for long periods of time. Anabolic steroids are used as off-label drugs (drugs which are used without regulatory approval) and have been used as adjuvants to usual treatment with dressings, debridement, nutritional supplements, systemic antibiotics and antiseptics, which are considered to be supportive in healing of pressure ulcers. Anabolic steroids are considered because of their ability to stimulate protein synthesis and build muscle mass. Comprehensive evidence is required to facilitate decision making, regarding the benefits and harms of using anabolic steroids. To assess the effects of anabolic steroids for treating pressure ulcers. In March 2017 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting. Published or unpublished randomised controlled trials (RCTs) comparing the effects of anabolic steroids with alternative treatments or different types of anabolic steroids in the treatment of pressure ulcers. Two review authors independently carried out study selection, data extraction and risk of bias assessment. The review contains only one trial with a total of 212 participants, all with spinal cord injury and open pressure ulcers classed as stage III and IV. The participants were

The microbial and chemical analysis of illicit drug samples from different areas of Pakistan i.e. Quetta, Karachi, Lahore and Islamabad was conducted in a cross-sectional study at National Institute of Health, Islamabad. The drug samples were confiscated by Anti Narcotics Force (ANF), Pakistan. Microbial analysis was done by estimating bioburden which revealed the presence of gram negative and positive bacteria's, fungus, Streptococcus, Staphylococcus species. Trypton soya agar was used for total aerobic count, MacConkey agar for gram-negative bacteria, Sabouraud dextrose agar for fungus and Vogel-Johnson agar for Streptococcus and Staphylococcus species. Colour tests were applied to identify the drug samples. Qualitative and quantitative analysis of suspected samples of Heroin, morphine, cocaine and acetic anhydride was made by employing different chromatographic techniques i.e. Thin-layer chromatography (TLC) and High-performance liquid chromatography (HPLC). The samples were found to be adulterated with paracetamol, diazepam and Dextromethorphen. Acetic anhydride was adulterated with hydrochloric acid (HCl). There is lack of information providing structured advice on responses to the consequences of illicit drug adulteration. Robust and rehearsed interventions and communication strategies would provide a basis for response for a wide variety of organisations. Research into the usefulness of media warnings about adulteration of illicit drugs is required.

2004-01-01

In children, steroid-resistant nephritic syndrome due to focal segmental glomerulosclerosis (FSGS) is frequently a progressive condition resulting in end-stage renal disease (ESRD). We report the response of 15 patients with steroid resistant FSGS to treatment with intravenous pulse cyclophosphamide (IVCP) and oral prednisone after 4 years of follow up. 5 patients had initial steroid resistance and 10 patients had late steroid resistance. All patients were treated with IVCP at a dose of 500 mg/m/day for four weeks followed by 40/mg/m on alternate days for 4 weeks and then tapered over next 4 weeks. All patients with initial resistance to steroids showed no response to IVCP and continued to be steroid resistant. 3 developed CRF during the observation period. The other 10 patients with late steroid resistance responded to IVCP but all were steroid dependent at the end of observation period. 5 could not be weaned from steroids during the IVCP period. The other 5 patients achieved relatively prolonged remission (7 months to 24 months), but eventually become steroid dependent. 67% of the steroid resistant FSGS become steroid dependent. Patient with initial steroid resistance did not respond to IVCP. We no correlation between IgM deposition and the response to therapy. The side effects of IVCP were negligible. Beneficial therapy for initial steroid-resistant FSGS remains to be determined. (author)

Effects of androgenic-anabolic steroids in athletes.

Science.gov (United States)

Hartgens, Fred; Kuipers, Harm

2004-01-01

. Generally, AAS seem to induce increments of aggression and hostility. Mood disturbances (e.g. depression, [hypo-]mania, psychotic features) are likely to be dose and drug dependent. AAS dependence or withdrawal effects (such as depression) seem to occur only in a small number of AAS users. Dissatisfaction with the body and low self-esteem may lead to the so-called 'reverse anorexia syndrome' that predisposes to the start of AAS use. Many other adverse effects have been associated with AAS misuse, including disturbance of endocrine and immune function, alterations of sebaceous system and skin, changes of haemostatic system and urogenital tract. One has to keep in mind that the scientific data may underestimate the actual untoward effects because of the relatively low doses administered in those studies, since they do not approximate doses used by illicit steroid users. The mechanism of action of AAS may differ between compounds because of variations in the steroid molecule and affinity to androgen receptors. Several pathways of action have been recognised. The enzyme 5-alpha-reductase seems to play an important role by converting AAS into dihydrotestosterone (androstanolone) that acts in the cell nucleus of target organs, such as male accessory glands, skin and prostate. Other mechanisms comprises mediation by the enzyme aromatase that converts AAS in female sex hormones (estradiol and estrone), antagonistic action to estrogens and a competitive antagonism to the glucocorticoid receptors. Furthermore, AAS stimulate erythropoietin synthesis and red cell production as well as bone formation but counteract bone breakdown. The effects on the cardiovascular system are proposed to be mediated by the occurrence of AAS-induced atherosclerosis (due to unfavourable influence on serum lipids and lipoproteins), thrombosis, vasospasm or direct injury to vessel walls, or may be ascribed to a combination of the different mechanisms. AAS-induced increment of muscle tissue can be attributed

2004-01-01

The Nuclear Smuggling International Technical Working Group (ITWG) is an international body of nuclear forensic experts that cooperate to deter the illicit trafficking of nuclear materials. The objective of the ITWG is to provide a common approach and effective technical solutions to governments who request assistance in nuclear forensics. The ITWG was chartered in 1996 and since that time more than 28 nations and organizations have participated in 9 international meetings and 2 analytical round-robin trials. Soon after its founding the ITWG adopted a general framework to guide nuclear forensics investigations that includes recommendations for nuclear crime scene security and analysis, the best application of radioanalytical methods, the conduct of traditional forensic analysis of contaminated materials, and effective data analysis to interpret the history of seized nuclear materials. This approach has been adopted by many nations as they respond to incidents of illicit nuclear trafficking

Phasic increases in brain dopamine are required for cue-directed reward seeking. While compelling within the framework of appetitive behavior, the view that illicit drugs hijack reward circuits by hyper-activating these dopamine transients is inconsistent with established psychostimulant pharmacology. However, recent work reclassifying amphetamine (AMPH), cocaine, and other addictive dopamine-transporter inhibitors (DAT-Is) supports transient hyper-activation as a unifying hypothesis of abuse...

Adolescents' use of alcohol, tobacco and illicit drugs in relation to prenatal alcohol exposure: modifications by gender and ethnicity.

Pfinder, Manuela; Liebig, Stefan; Feldmann, Reinhold

2014-01-01

The study aimed to investigate (a) the association between low to moderate prenatal alcohol exposure (PAE) and the use of alcohol, tobacco and illicit drugs in adolescence and (b) whether the associations are modified by gender and ethnicity. The subjects of the study were 5922 children and adolescents, aged from 11 to 17 years, enrolled in the cross-sectional German Health Interview and Examination Survey for Children and Adolescents (the KiGGS study). Information on PAE is based on parental self-report questionnaires. Use of alcohol, tobacco and illicit drugs was assessed through self-report questionnaires for adolescents. Low to moderate PAE was associated with an increased risk of drinking alcohol (adjusted odds ratio (OR) 1.73, 95% confidence interval (CI) 1.34, 2.18) and also of illicit drug use (adjusted OR 1.62, 95% CI 1.23, 2.14). The associations between PAE and the use of alcohol, tobacco and illicit drugs differed according to gender and ethnicity. Gender-stratified analyses resulted in adverse effects of PAE on drinking alcohol, smoking and illicit drug use in females; however, in German males, the associations disappeared. Stronger associations between PAE and the outcome measures were found in non-Germans. Our findings indicate that low to moderate levels of maternal alcohol intake during pregnancy are a risk factor for use of alcohol, tobacco and illicit drugs by the offspring, with stronger associations in females and non-Germans.

This study sought to identify the risk indicators associated with the consumption of illicit drugs by schoolchildren in public schools in a community in the south of Brazil. This is a non-experimental cross-sectional study conducted with 535 students of primary schoolchildren from six public schools. Data were collected using a questionnaire between October 2011 and March 2012. The results were presented by simple and relative distribution of frequency and odds ratio (OR) and the 95% reliability intervals were calculated to verify the association between the dependent and independent variables. Multivariate analysis was also performed using the question "have you ever used illicit drugs?" Univariate analysis revealed an association between family income, color, period in which the child studied, failure to pass annual tests, use of methods of prevention, smoking habit and knowing someone who uses drugs with the fact of having experimented with the use of illicit drugs. After multivariate analysis, the smoking habit was the only indicator significantly associated with the question of having made use of illicit drugs. The results indicate that the smoking habit is an important indicator of the predictive risk for the use of illicit drugs.

Efforts of Turkey in combating with illicit trafficking of nuclear materials and other radioactive sources

International Nuclear Information System (INIS)

Yucel, F.A.; Akats, N.; Yilmazer, A.

2001-01-01

Full text: Illicit trafficking of nuclear materials and other radioactive sources creates both non-proliferation problems and also is a radiation hazard risk for the law enforcement officers, public and the environment. Since the illicit trafficking and trading of nuclear materials and other radioactive sources has been increasing over the past years, it is very important to take immediate measures for preventing these activities. Turkey, as a country having a unique position at the crossing points of the two major routes - one connecting the Black Sea to the Mediterranean and the other connecting Europe to Asia and the Middle East - is situated on the routes of illicit trafficking. Thus, Turkey attaches great importance to combating illicit trafficking and strongly supports all efforts in this field. After the IAEA resolution GC(XXXVIII)RES/15 requesting Member States to 'take all necessary measures to prevent illicit trafficking in nuclear materials' had been adopted, Turkey gave full support to the IAEA Programme on Combating Illicit Nuclear and other Radioactive Materials and also took some measures to combat such trading. Regulatory activities regarding nuclear and radiological safety, including safeguards and physical protection in Turkey, are under the responsibility of the Turkish Atomic Energy Authority (TAEA). The TAEA ensures that the licensed activities do not cause any unreasonable risk to the public and to environmental safety and that they do not impair the common defense and security interest of Turkey. TAEA was established by the Act No.2690 of 9th July 1982 and replaced the Turkish Atomic Energy Commission created by the Act No.6821 in 1956. The Act No.2690 Authorizes the TAEA to carry out the activities connected with the fulfillment of Turkey's obligations arising from international agreements in the field of safeguards and physical protection. This paper covers the efforts and coordination role of TAEA's planned activities and the measures

Circulating steroids negatively correlate with tinnitus.

Chrbolka, Pavel; Palúch, Zoltán; Hill, Martin; Alušík, Štefan

2017-07-01

While not a disease entity in itself; symptoms of tinnitus (from Latin tinnio - clink) accompany a number of diseases. Tinnitus prevalence increases with age, deteriorates one's quality of life, and may even result in suicidal behavior. Tinnitus develops in response to a variety of risk factors, otoxic substances, noise exposure, hearing disorders, and psychological alterations. Tinnitus is closely related to mood, depression, and psychological state. In the present study, we focused on alterations of the steroid metabolome and particularly neuroactive, neuroprotective, and immunomodulatory steroids in patients with tinnitus. The study group consisted of 28 patients without evidence of an organic cause of tinnitus as well as without associated diseases or the effect of ototoxic medications. All patients underwent a complete audiological assessment and laboratory tests including routine biochemical markers and quantification of circulating steroids using gas chromatography/mass spectrometry and immunoassays. To rule out a pathology in the cerebellopontine angle area, CT scan or MRI were performed. To diagnose stem lesions, evoked potentials were also measured. Pearson's correlations and multivariate regression were used to assess any links between tinnitus intensity and frequency on the one hand, and steroid levels on the other. Results indicated a significant and consistent negative correlation between tinnitus indices and intensity of adrenal steroidogenesis. The circulating steroid metabolome including hormones and neuroactive, neuroprotective, and immunomodulatory steroids negatively correlates with the degree of tinnitus due to hypothalamo-pituitary-adrenal axis malfunction.

Since more than a decade illicit Trafficking of hazardous ( CBRNE), materials ( chemical, biological, radiological, nuclear and explosive ) has been identified as a key threat in national, regional, inter regional and international strategies. An Effective response to hazardous materials (CBRNE) risk and threat were realized to require a very high level of cooperation and coordination between various governments and their responsible organizations and authorities of regional and international partner. While improper policy of actions may easily be exploited by non- state members to (CBRNE) trafficking which may lead to develop weapon of mass destruction (WMD). Such strategy are of paramount important between all levels of the states and among regional agreements through comprehensive tailored assistance packages (e.g. export control, illicit trafficking of hazardous materials, redirection of scientist, emergency planning, crisis response safety and security culture. Capacity building, action plans and instruments for stability are necessary actions for efficient combating against illicit trafficking of hazardous materials. Regarding the needs of assessment phase, assistance must be based on data collection, analysis and prioritization of implanting the regulatory controls. Several activities have to be conducted to reduce CBRNE threat. The one- by- one approach, covering either nuclear and radioactive or chemical or biological materials has to be implanted on the country basis performance to mitigate CBRNE hazardous risk. On several consequent phases of intervention dealing with CBRNE risk mitigation the country has to establish a network of local, regional and international capabilities. Such network is setting up the mechanism for the country needs identifications, the guidelines for data collection, for data platform maintenance and update, the data assessment and the competent and operative organizations. This network will be to strengthen the long - term

Illicit drug use among adolescent students. A peer phenomenon?

Illicit drug use was studied in 2071 students 11 to 18 years of age. Almost all drug users had friends who consumed drugs, compared with only one third of those who did not use drugs. This suggests a bond between adolescent drug users, who form a distinct group of which most students are unaware.

Correlates of Illicit Drug Use Among Indigenous Peoples in Canada: A Test of Social Support Theory.

2018-02-01

Relying on a national stratified random sample of Indigenous peoples aged 19 years old and above in Canada, this study investigates the correlates of illicit drug use among Indigenous peoples, paying special attention to the association between social support measures and illegal drug use. Results from multivariate logistical regression show that measures of social support, such as residential mobility, strength of ties within communities, and lack of timely counseling, are statistically significant correlates of illicit drug use. Those identifying as Christian are significantly less likely to use illegal drugs. This is the first nationwide analysis of the illicit drug usage of Indigenous peoples in Canada. The results are robust because we have controlled for a range of comorbidity variables as well as a series of sociodemographic variables. Policy implications from these findings are discussed.

Ek, P.; Wredberg, L.

Full text: Illicit trafficking activities involving nuclear material and equipment are acts of nuclear proliferation. The threat of illicit trafficking is an international concern and the consequences of illicit trafficking, such as war or terrorist attacks using illegally manufactured nuclear weapons, might affect any country. As long as these materials and equipment remain a potential for theft and smuggling due to insufficient security and control conditions, there is a possibility that proliferators or terrorist groups may illegally take possession of such materials and equipment for illicit purposes. A precondition for preventing illicit trafficking is the existence of effective national systems for supervision and control of nuclear material and equipment, including physical protection and export/import control, based on an accurate and complete legislation. In addition thereto, national systems for combating of illicit trafficking, through prevention and detection within a state's territory or across its borders, incorporate such components as: supervision and control of nuclear operations; organisation of operator activities through quality assurance, internal control, security culture, etc.; law enforcement functions (police, intelligence, customs, investigation, prosecution, penalties and sanctions); and procedures for co-ordination and co-operation between supervising and law enforcement authorities. According to a joint Swedish-Norwegian-Latvian study, there are imperfections in many national systems for combating of illicit trafficking, such as: Incomplete legislation on nuclear non-proliferation and safety, physical protection and export/import control; Unclear or overlapping responsibilities between national supervision and law enforcement authorities, leading to poor co-operation and co-ordination of preventing and detecting measures; Incomplete rules and regulations concerning operator functions and responsibilities, including requirements on

Ibuprofen versus steroids: risk and benefit, efficacy and safety

Directory of Open Access Journals (Sweden)

2013-10-01

Full Text Available In the last few years we have observed an upward trend in the employment of ibuprofen as anti-inflammatory and antipyretic therapy. Therefore the pediatrician has often a precious option in the anti-inflammatory and antipyretic treatment in children instead of using steroids and paracetamol. In clinical practice ibuprofen can be used in the treatment of headache, toothache, otalgy, dysmenorrhea, neuralgia, arthralgia, myalgia, abdominal pain and fever: it is the first choice for these common diseases. However, the use of steroids is a routine, even if non-corticosteroid anti-inflammatory molecules could be useful. Certainly steroids are powerful anti-inflammatory, indicated for the treatment of chronic inflammatory disorders and in acute respiratory and allergic diseases. Beside, thanks to their chemical and pharmacological profile, they also provide patients with an antipyretic effect. However, the use of steroids must be reserved to cases in which other classical antipyretics such as non-steroidal anti-inflammatory drugs are not effective. The possible side effects and risks associated with stepping down steroids must be considered. Although “steroids-phobia” should be discouraged, steroids are to be reserved only as the first indication. In all other cases the pediatrician can use ibuprofen, whose efficacy and safety are widely demonstrated by now.

Yilmazer, A.; Yuecel, A.; Yavuz, U.

2001-01-01

As it is known, for the fact that the illicit trafficking and trading of nuclear materials are being increased over the past few years because of the huge demand of third world states. Nuclear materials like uranium, plutonium, and thorium are used in nuclear explosives that have very attractive features for crime groups, terrorist groups and, the states that are willing to have this power. Crime groups that make illegal trade of nuclear material are also trying to market strategic radioactive sources like red mercury and Osmium. This kind of illegal trade threats public safety, human health, environment also it brings significant threat on world peace and world public health. For these reasons, both states and international organizations should take a role in dealing with illicit trafficking. An important precondition for preventing this kind of incidents is the existence of a strengthened national system for control of all nuclear materials and other radioactive sources. Further, Governments are responsible for law enforcement within their borders for prevention of illegal trading and trafficking of nuclear materials and radiation sources

Thuan, C E; Huat, L B

1989-06-01

The abuse of phenylbutazone among rheumatoid arthritis patients has recently become a subject of interest. Unscrupulous manufacturers take advantage of the miraculous analgesic property of phenylbutazone and deliberately add this toxic drug in their preparations without declaring its presence on the label. In a recent survey, many such illicit preparations were seized from Chinese medical halls in Johor and sent to the Department of Chemistry, Johor Bahru for analysis. Here a Gas Chromatograph Mass Selective Detector (GC-MSD) method was developed for the determination of phenylbutazone in illicit traditional preparations.

2003-01-01

AIM, DESIGN AND SETTING: The economic costs of alcohol, tobacco and illicit drugs to French society are estimated using a cost of illness framework. For the cause of disease or death (using ICD-9 categories), pooled relative risk estimates from meta-analyses were combined with prevalence data by age and gender to derive the proportion attributable to alcohol, tobacco and/or illicit drugs. The resulting estimates of attributable deaths and hospitalizations were used to calculate the associated health care, law enforcement, productivity and other costs. The results were compared with those of other studies, and sensitivity analyses were conducted by alternative ways of measuring risk attribution and costs. The use of alcohol, tobacco and illicit drugs cost more than 200 billion francs (FF) in France in 1997, representing 3714 FF per capita or 2.7% of the gross domestic product (GDP). Alcohol is the drug that gives rise to the greatest cost in France, i.e. 115420.91 million FF (1.42% of GDP) or an expenditure per capita of 1966 FF in 1997. Alcohol takes more than half of the social cost of drugs to society. The greatest share of the social cost of alcohol comes from the loss of productivity (57555.66 million FF), due to premature death (53168.60 million FF), morbidity (3884.0 million FF) and imprisonment (503.06 million FF). Tobacco leads to a social cost of 89256.90 million FF, that is an expenditure per capita of 1520.56 FF or 1.1% of GDP. Productivity losses amount to 50446.70 million FF, with losses of 42765.80 million FF as a result of premature death and 7680.90 million FF linked to morbidity. Health care costs for tobacco occupy second place at 26973.70 million FF. Illicit drugs generate a social cost of 13350.28 million FF, that is an expenditure per capita of 227.43 FF or 0.16% of GDP. Productivity losses reach 6099.19 million FF, with 5246.92 million FF linked to imprisonment and 852.27 million FF to premature death. The cost of enforcing the law for illicit

Background Testing for illicit drugs may expose women who test positive to severe legal and social consequences. It is unknown whether racial disparities in drug testing practices underlie observed disparities in legal and social consequences of positive tests. Methods Using administrative hospital and birth certificate data, we analyzed factors associated with both receipt and results of illicit drug testing among women with live births during 2002–2003. We assessed the independent association of race and other sociodemographic factors with both receipt of a drug test by the mother or her newborn infant and positive maternal or neonatal toxicology results, after controlling for obstetrical conditions and birth outcomes associated with maternal substance abuse. Results Of the 8487 women with live births, 244 mother-newborn pairs (3%) were tested for illicit drug use. Black women and their newborns were 1.5 times more likely to be tested for illicit drugs as nonblack women in multivariable analysis. However, race was not independently associated with a positive result. Conclusions We identified racial differences in rates of testing for illicit drug use between black and nonblack women. We found equivalent positivity rates among tested black and nonblack women. The prevalence of drug use among untested women is unknown, however, so although tested women had equivalent rates of substance use detected, whether black and nonblack substance users are equally likely to be identified in the course of peripartum care remains uncertain.

Although topical steroid addiction or red burning skin syndrome had been mentioned as possible side effects of topical steroids in a 2006 review article in the Journal of the American Academy of Dermatology, no statement was made regarding this illness in the new guidelines. This suggests that there are still controversies regarding this illness. Here, we describe the clinical features of topical steroid addiction or red burning skin syndrome, based on the treatment of many cases of the illness. Because there have been few articles in the medical literature regarding this illness, the description in this article will be of some benefit to better understand the illness and to spur discussion regarding topical steroid addiction or red burning skin syndrome.

Full Text Available Illicit drug abuse is a major area of interest for clinicians, as well as for public health and social authorities, but one of the major concerns is the illicit drug abuse during the periconceptional period and throughout pregnancy, because of its potential effects on the embryo and fetus. In this study we investigated the prevalence of illicit drug abuse in the first trimester of pregnancy in women who referred to Iran, Tehran and Shahid Beheshti universities of medical sciences, for prenatal care."nMaterials and Methods: In this descriptive cross sectional study, a non-randomized sample of 2000 pregnant women that were in their second and third trimester of their pregnancy, were interviewed about drug abuse in their first trimester. Collected data were analyzed by SPSS software."nResults: The prevalence of illicit drug abuse in the first trimester was 2.5% which the majority of these drugs were in group B. The prevalence of drug abuse was 0.9% and alcohol usage and alcohol abuse was 0.2%, cigarette smoking was the most common drug abusing phenomena. Variables such as husband education, infertility and satisfaction with pregnancy have significant relation with drug abuse."nConclusion: The results of this study support the need for continued education and this education must end in by itself to make dramatic changes in behavior. So results of this study showed that, improving education and knowledge of mothers and consultation with them in regard to risks and complications of drug abuse during pregnancy, would make dramatic changes in their behavior."n"n"n"n"n"n"n"n

Preparation of directly iodinated steroid hormones and related directly halogenated compounds

International Nuclear Information System (INIS)

Sahadevan, V.

1981-01-01

The preparation of directly iodinated radioactive steroid hormones is described for use in radioimmunoassays or radiolocalization and treatment of human breast tumours. The radioactive iodinated steroid hormone is prepared by reacting a parent steroid hormone with an alkali metal iodide containing radioactive 123 I, 125 I, 130 I or 131 I in the presence of hydrogen peroxide or chloramine-T. The parent steroid hormones include the adrenal corticosteroids, the estrogens, the progestogens, the progestins and the diuretic and antidiuretic agents. The radioactive iodinated steroid hormone is prepared by iodinating the parent steroid hormone directly on the cyclopentanophenanthrene nucleus. The radioactive iodinated steroid hormones have the same antigenicity and receptor site specificity as the parent steroid hormone. The invention is illustrated by 1) the method of iodination of estradiol-17β, 2) results for the percentage labelling of several steroids and steroid hormones, 3) results for the radioimmunoassay of 125 I-estradiol and 4) results for the binding of directly iodinated estradiol-17β in an estrogen receptor assay of human breast cancer.

Studies show that illicit cannabis (marijuana) use is related to use of other illicit drugs and that reasons for use are related to frequency of marijuana use. However, research is needed to examine whether specific reasons for marijuana use are associated with use of other illicit drugs. Data from recent marijuana-using high school seniors were examined from 12 cohorts of Monitoring the Future (Weighted n = 6481) to examine whether reasons for recent marijuana use are associated with use of eight other illicit drugs. Using "to experiment" decreased odds of reporting use of each drug and using to decrease effects of other drugs increased odds of reporting use of each drug. In multivariable models, using marijuana "to experiment" decreased the odds for reporting use of hallucinogens other than LSD and narcotics other than heroin. Using marijuana for "insight" increased the odds for use of hallucinogens other than LSD, and use due to "boredom" increased the odds for reporting use of powder cocaine and hallucinogens other than LSD. Using marijuana to increase effects of other drugs increased odds of reporting use of each of the eight drugs, and using it to decrease other drug effects increased odds of reporting use of crack, hallucinogens other than LSD, and amphetamine/stimulants. This study helped identify illicit marijuana users who are more likely to report use of other illicit drugs. Prevention efforts need to focus on students who report certain reasons for marijuana use as they may be at risk for use of other illicit drugs.

Nonmedical use of prescription opioid and illicit opioid has been increasing at an alarming rate in North America over the past decade. We sought to examine the temporal trends and correlates of the availability of illicit and prescription opioids among people who inject drugs (PWID) in Vancouver, Canada. Data were derived from three prospective cohort studies of PWID in Vancouver between 2010 and 2014. In semiannual interviews, participants reported the availability of five sets of illicit and prescription opioids: (1) heroin; (2) Percocet (oxycodone/acetaminophen), Vicodin (hydrocodone/acetaminophen), or Demerol (meperidine); (3) Dilaudid (hydromorphone); (4) Morphine; (5) oxycontin/OxyNEO (controlled-release oxycodone). We defined perceived availability as immediate (e.g., available within 10 minutes) versus no availability/available after 10 minutes. The trend and correlation of immediate availability were identified by multivariable generalized estimating equations logistic regression. Among 1584 participants, of which 564 (35.6%) were female, the immediate availability of all illicit and prescribed opioids (except for oxycontin/OxyNEO) increased over time, independent of potential confounders. The Adjusted Odds Ratios of immediate availability associated with every calendar year increase were between 1.09 (95% confidence interval 1.05-1.12) (morphine and Dilaudid) and 1.13 (95% confidence interval 1.09-1.17) (Percocet/Vicodin/Demerol) (all p-values illicit and prescription opioid use among PWID that could potentially increase the risk of overdose.

The Nuclear Smuggling International Technical Working Group (ITWG) is an international group of nuclear forensic experts that cooperate to deter the illicit trafficking of nuclear materials. The objective of the ITWG is to provide a common approach and effective technical solutions to governments who request assistance in nuclear forensics. The ITWG was chartered in 1996 and since that time more than 28 nations and organizations have participated in 9 international meetings and 2 analytical round-robin trials. Soon after its founding the ITWG adopted a general framework to guide nuclear forensics investigations that includes recommendations for nuclear crime scene security and analysis, the best application of radioanalytical methods, the conduct of traditional forensic analysis of contaminated materials, and effective data analysis to interpret the history of seized nuclear materials. This approach has been adopted by many nations as they respond to incidents of illicit nuclear trafficking. ITWG members include policy and decision makers, law enforcement personnel, and scientists with expertise in, and responsibility for, nuclear forensics. (author)

NELIS - a Neutron Inspection System for Detection of Illicit Drugs

International Nuclear Information System (INIS)

Barzilov, Alexander P.; Womble, Phillip C.; Vourvopoulos, George

2003-01-01

NELIS (Neutron ELemental Inspection System) is currently being developed to inspect cargo pallets for illicit drugs. NELIS must be used in conjunction with an x-ray imaging system to optimize the inspection capabilities at ports of entry. Pulsed fast-thermal neutron analysis is utilized to measure the major and minor chemical elements in a non-destructive and non-intrusive manner. Fourteen-MeV neutrons produced with a pulsed d-T neutron generator are the interrogating particles. NELIS analyzes the characteristic gamma rays emitted from the object that are produced by nuclear reactions from fast and thermal neutrons. These gamma rays have different energies for each chemical element, and act as their fingerprints. Since the elemental composition of illicit drugs is quite different from that of innocuous materials, drugs hidden in pallets are identified through the comparison of expected and measured elemental composition and ratios. Results of tests of the system will be discussed

Characterization of Steroidal Saponins from Dioscorea villosa and D. cayenensis Using Ultrahigh Performance Liquid Chromatography/Electrospray Ionization Quadrupole Time-of-Flight Mass Spectrometry

Yam (Dioscorea spp.) is an important edible tuber plant used for medicinal purposes to promote health and longevity in Chinese tradition. Steroidal saponins were reported to be the major physiologically active constituents in yams. In this current work, the structural characteristics of steroidal saponins in methanolic extracts from dried rhizomes of two Dioscorea species (D. villosa L. and D. cayenensis Lam.) and dietary supplements have been identified and analyzed using UHPLC/QTOF-MS in both negative and positive ion modes. The fragmentation patterns of reference standards were determined and the steroidal saponins in the extracts were identified or tentatively characterized from their retention times and mass spectra. The fragments produced by collision-induced dissociation (CID) revealed the characteristic cleavage of glycosidic bonds, and the fragmentation pattern provided structural information about the sugars. Twenty-one saponins, including four tentatively identified compounds, were detected in the crude extracts of two Dioscorea species. These saponins can be used to distinguish D. villosa from D. cayenensis. For example, asperin and gracillin are found only in D. cayenensis, and dioscoreavilloside A and B and parvifloside are only found in D. villosa. This can be used to determine the presence or absence of D. villosa in commercial products, which may help determine the spiking of plant material, and/or prevent the use of potentially mislabeled or misidentified “Dioscorea” material. The analytical method also provided an alternative, fast method for quality control of Dioscorea species in dietary supplements. Principal component analysis showed that Dioscorea species and commercial products were easily distinguished. From this a partial least squares model was constructed to determine what species are in different products. PMID:24510365

By month 36, 32.4% and 51.7% of patients in the steroid avoidance and steroid withdrawal groups, respectively, were receiving oral steroids. In conclusion, IL-2RA induction with early intensified EC-MPS dosing and CNI therapy in de novo kidney transplant patients at low immunological risk may achieve similar three-year efficacy regardless of whether oral steroids are withheld for at least three months.

Do mollusks use vertebrate sex steroids as reproductive hormones? Part I: Critical appraisal of the evidence for the presence, biosynthesis and uptake of steroids.

Science.gov (United States)

Scott, Alexander P

2012-11-01

The consensus view is that vertebrate-type steroids are present in mollusks and perform hormonal roles which are similar to those that they play in vertebrates. Although vertebrate steroids can be measured in molluscan tissues, a key question is 'Are they formed endogenously or they are picked up from their environment?'. The present review concludes that there is no convincing evidence for biosynthesis of vertebrate steroids by mollusks. Furthermore, the 'mollusk' genome does not contain the genes for key enzymes that are necessary to transform cholesterol in progressive steps into vertebrate-type steroids; nor does the mollusk genome contain genes for functioning classical nuclear steroid receptors. On the other hand, there is very strong evidence that mollusks are able to absorb vertebrate steroids from the environment; and are able to store some of them (by conjugating them to fatty acids) for weeks to months. It is notable that the three steroids that have been proposed as functional hormones in mollusks (i.e. progesterone, testosterone and 17β-estradiol) are the same as those of humans. Since humans (and indeed all vertebrates) continuously excrete steroids not just via urine and feces, but via their body surface (and, in fish, via the gills), it is impossible to rule out contamination as the sole reason for the presence of vertebrate steroids in mollusks (even in animals kept under supposedly 'clean laboratory conditions'). Essentially, the presence of vertebrate steroids in mollusks cannot be taken as reliable evidence of either endogenous biosynthesis or of an endocrine role. Crown Copyright © 2012.

2017-08-01

Full Text Available Current descriptive and qualitative study described feelings and codependent behavior in relatives of illicit drug users. Data were collected between March and April 2012 by an open interview with eight family members of illicit drugs-dependent individuals and subjected to theme-mode content analysis. Results were classified into two categories which showed intense suffering coupled to feelings of guilt, fear, shame, sadness, shame and manifestation of codependent behaviors such as denial and control of the one´s situation and that of others. Professionals should know the situation in which the families of drug addicts live to assist them in a different way. They should also identify codependent relatives, since they also need care so that their behavior does not worsen the symptoms and behavior of the drug user and prevents a possible medical or psychiatric diagnosis.

The alteration of the urinary steroid profile under the stress

Directory of Open Access Journals (Sweden)

A Gronowska

2010-03-01

Full Text Available In the second part of twentieth century anabolic-androgenic steroids were introduced into doping practice and received continuously increasing significance. In order to prove the usage of doping substances, the determination of steroid profile in the urine came into practice. Several factors may be responsible for alterations in the normal steroid profile for example age, sex and diet. The aim of this study was to find out, whether the psychological stress may cause modifications in the steroid profile and T/Et ratio. The effect of physical activity was also considered. The steroid profile was determined in the group of 34 students being in non-stress conditions and under stress immediately before an important university exam. The intensity of stress was rated by self-reported questionnaire. The GC/MS method was applied to determine the steroid profile in the urine samples. The results of the experiment have shown that psychological stress may cause significant changes in the steroid profile, especially in females. Physical activity, independently of stress significantly modified the steroid profile. In summary, observed changes in steroid profile suggest, that major fluctuations of T/Et and A/E ratios under the influence of stressogenic factors and physical activity are unlikely.

Full Text Available In this article we will discuss the challenges involved in presenting the looting of archaeological sites and the illicit trade in cultural property to the interested public. We will contrast our experiences of building two popular illicit antiquities-focused blogs (Things You Can't Take Back and Anonymous Swiss Collector with the process of developing an informative academic website on the same topic (Trafficking Culture. We will discuss our motivations for starting these blogs, our struggles with the tone of the popular discourse on this topic, and our inability to escape our own emotions; why we have moved away from illicit antiquities blogging in the past year and why we are coming back. Finally, having learned from our mistakes, we will make recommendations to others wishing to engage with the public about sensitive issues via social media.

Prescription of the High Risk Narcotics and Trading or Illicit Purchasing of High Risk Narcotics

Directory of Open Access Journals (Sweden)

Nicoleta-Elena Buzatu

2012-05-01

Full Text Available The present essay will analyze the offence of prescribing high risk narcotics and trading or illicit purchasing of high risk narcotics, as it was regulated - together with other offences - by Law no 143 of July 26, 2000 on preventing and fighting against the traffic and illicit consumption of narcotics. The same law defines the meaning of such a phrase “substances which are under national control” by mentioning the fact that they are the narcotics and their precursors listed in Annexes I-IV of the law. The analysis of the offence of prescribing the high risk narcotics and trading or illicit purchasing of high risk narcotics is following the already known structure mentioned in the doctrine and which consists of: object and subjects of the offence, its constituent content: the objective side with its material element, the immediate consequence and causality connections; the subjective side of the offence, as well as forms and modalities of these offences, and the applicable sanctions, of course.

Stopping Illicit Procurement: Lessons from Global Finance

Energy Technology Data Exchange (ETDEWEB)

Hund, Gretchen; Kurzrok, Andrew J.

2014-06-19

Government regulators and the financial sector cooperate to combat money laundering and terrorist financing. This information-sharing relationship is built upon a strong legislative foundation and effective operational procedures. As with money-laundering and terrorist financing, halting the illicit procurement of dual-use commodities requires close coordination between government and industry. However, many of the legal and operational features present in financial threat cooperation do not exist in the export control realm. This article analyzes the applicability of financial industry cooperative measures to nonproliferation.

2008-07-01

Data from the 2001 College Alcohol Study, a national sample of U.S. college students, were used to conduct multinomial logistic regression analysis examining correlates of substance use. Students were divided into three groups based on their lifetime substance use: non-users, non-medical prescription drug use only, and illicit/street drug use only. The purpose of this analytic strategy was to examine the similarities/differences in the correlates of non-medical prescription drug use and illicit/street drug use. Findings indicate that race, age, G.P.A., sexual activity, health, binge drinking, marijuana use, social bonding and social learning measures are correlates of non-medical prescription drug use. Correlates of illicit/street drug use include gender, Hispanic ethnicity, sexual activity, binge drinking, marijuana use, social bonding and social learning measures. Finally, the focus of the paper is a comparison of students who report only non-medical prescription drug use to students who report only illicit/street drug use. Findings indicate that gender, race, marital status, sexual activity, marijuana use, and social bonding measures significantly distinguish illicit/street drug use from non-medical prescription drug use. Important implications, limitations, and future research needs were discussed.

The aim of this study was to investigate the prevalence and pattern of psychoactive substances among suspected DUID (Driving Under the Influence of Drugs) drivers in Hungary in 2014 and 2015. Blood and/or urine samples of 1252 suspected drivers (600 in 2014 and 652 in 2015) were analyzed for classical illicit and licit drugs, stimulant designer drugs (SDDs), and for synthetic cannabinoids, with 78.3% and 79.6% positive cases for at least one substance in 2014, and 2015, respectively. Impairment was proven in 39.2% (2014) and 35.7% (2015) of all drivers tested, based on the legal criteria of Hungary. Classical illicit drugs were found to be present in blood or urine of 89-61%, drivers tested. Drivers also tested positive for legal medications in 20-22%, SDDs in 21-28%, and synthetic cannabinoids in 15-19% of all cases. This indicates a drop in prevalence for classical illicit drugs and a slight but statistically non-significant increase for the other three substance groups. The distribution of drug types in each category were: [1] classical illicit drugs: cannabis (432), amphetamine (321), and cocaine (79); [2] medicines: alprazolam (94) and clonazepam (36); [3] SDDs: pentedrone (137) and α-PVP (33); [4] synthetic cannabinoids: AB-CHMINACA (46) and MDMB-CHMICA (30). The average age of illicit drug and SDD users was 30 years, while legal medications users were 36 years old on average, and the mean age of synthetic cannabinoid users was 26.5 years. The presence of both alcohol and at least one drug in samples was found in about 10% of the cases, both years. The ratio of multi-drug use was 33.0% in 2014 and 41.3% in 2015. Compared to former years the number of drivers who tested positive for drugs doubled in Hungary, but it is still low compared to alcohol positive cases. The relatively low detected rate of DUID can be explained by (1) combined alcohol consumption masking drug symptoms, (2) the absence of road-side tests for illicit and designer drugs and, (3) police

Anabolic steroid abuse causing recurrent hepatic adenomas and hemorrhage

Martin, Nicole M; Dayyeh, Barham K Abu; Chung, Raymond T

2008-01-01

Anabolic steroid abuse is common among athletes and is associated with a number of medical complications. We describe a case of a 27-year-old male bodybuilder with multiple hepatic adenomas induced by anabolic steroids. He initially presented with tumor hemorrhage and was treated with left lateral hepatic segmentectomy. Regression of the remaining tumors was observed with cessation of steroid use. However, 3 years and a half after his initial hepatic segmentectomy, he presented with recurrent tumor enlargement and intraperitoneal hemorrhage in the setting of steroid abuse relapse. Given his limited hepatic reserve, he was conservatively managed with embolization of the right accessory hepatic artery. This is the first reported case of hepatic adenoma re-growth with recidivistic steroid abuse, complicated by life-threatening hemorrhage. While athletes and bodybuilders are often aware of the legal and social ramifications of steroid abuse, they should continue to be counseled about its serious medical risks. PMID:18680242

Steroid withdrawal in renal transplant patients: the Irish experience.

LENUS (Irish Health Repository)

Phelan, P J

2012-02-01

BACKGROUND: Steroid therapy is associated with significant morbidity in renal transplant recipients. However, there is concern that steroid withdrawal will adversely affect outcome. METHODS: We report on 241 renal transplant recipients on different doses of corticosteroids at 3 months (zero, <\\/= 5 mg\\/day, > 5 mg\\/day). Parameters analysed included blood pressure, lipid profile, weight change, new onset diabetes after transplantation (NODAT), allograft survival and acute rejection. RESULTS: Elimination of corticosteroids had no impact on allograft survival at 1 year. There were no cases of NODAT in the steroid withdrawal group compared with over 7% in each of the steroid groups. There were no significant improvements in weight gain, blood pressure control or total cholesterol with withdrawal of steroids before 3 months. CONCLUSIONS: In renal transplant patients treated with tacrolimus and mycophenolate, early withdrawal of steroids does not appear to adversely affect allograft outcome at 1 year. It may result in less NODAT.

Iriart, Jorge Alberto Bernstein; Chaves, José Carlos; Orleans, Roberto Ghignone de

2009-04-01

This study focused on the reasons for practicing bodybuilding and the use of anabolic steroids, as well as the social representations and uses of the body among bodybuilding steroid users. This ethnographic study involved participant observation in middle and lower-class bodybuilding gyms in Salvador, Bahia State, Brazil, and 43 in-depth interviews with steroid users. Aesthetic reasons are the main motivation for bodybuilding and steroid use in both middle and lower-class users. Dissatisfaction with one's real body as compared to the ideal standard flaunted by the mass media, fear of being devalued or shunned by one's peer groups, the symbolic capital associated with a 'pumped-up' body, and the sense of immediacy in obtaining results all contributed to steroid use. Preventive campaigns are needed, targeting young people and combining a critical view and deconstruction of the values assigned to the body by consumer society, counteracted by high-quality information on the health risks associated with anabolic steroid use.

Retrospectively study.The purpose of this study was to compare the effects of intraoperative epidural steroids and single dose intravenous steroids following a percutaneous endoscopic lumbar discectomy (PELD).Inflammatory irritation of dorsal root ganglia or sensory nerve roots may cause postoperative pain. Epidural steroids have been applied after a lumbar discectomy for more than 20 years. Epidural steroid application after a PELD is easier to perform and safer because the operations are under observation of the scope.We retrospectively reviewed the medical records of patients with lumbar intervertebral disc herniation who had undergone transforaminal PELD at our department. There are 60 patients in epidural steroid group, intravenous steroid group, and control group, respectively. Visual analog scores (VAS) and the Oswestry Disability Index (ODI) were collected. Successful pain control is defined as 50% or more reduction in back and leg pain (VAS scores).VAS scores (back and leg) and ODI showed a significant decrease in all groups when comparing pre- and postoperatively. Epidural steroid group had a significant improvement in successful pain control compared with the control group at 2 weeks of follow-up. VAS scores (leg) in the epidural steroid group showed a significant decrease compared with the intravenous steroids group at 1, 3, and 7 days after the surgery, but this difference had no statistical significance at 1, 6, and 12 months of follow-up. All groups did not show a significant difference in ODI at 1, 6, and 12 months follow-up.Epidural application of steroid has a better effect on controlling the postoperative pain of PELD in the short term. The epidural application of steroid did not show a tendency to cause infection.

The purpose of this study was to estimate the prevalence of recent use of illicit drugs among truck drivers who had parked their vehicles at the terminal port in Paranaguá City at Paraná State, southern Brazil. This cross-sectional study was part of a larger research project conducted among drivers at a regional Brazilian port. Data on professional characteristics, involvement in road traffic injuries, sleep, and use of alcohol and illicit drugs were collected using a questionnaire. Urine samples were collected and analyzed for amphetamines, cocaine, and cannabis using gas chromatography with mass spectrometric detection. Sixty-two drivers were included in the study. Toxicological analyses showed that 8.1 percent (95% confidence interval [CI], 2.7-17.8%) of the urine samples were positive for drugs (4.8% for cocaine, 1.6% for amphetamine, and 1.6% for both); 8.1 percent reported drug use during the preceding 30 days in the questionnaire and only one tested positive for the drug in the urine sample. No sample was positive for cannabinoids. In total, at least 14.5 percent (95% CI, 6.9-25.8%) had used illicit drugs during the preceding 30 days based on self-reports and urine testing. Drivers who reported involvement in traffic injuries the year before more often tested positive for drugs in biological samples (P illicit stimulants was common among professional truck drivers transporting grain loads. Thus, actions are needed to reduce drug use among truck drivers in order to prevent drug-related road traffic injuries.

Fractionation of fecal neutral steroids by high performance liquid chromatography

Jackson, E.M.; Kloss, C.A.; Weintraub, S.T.; Mott, G.E.

1985-01-01

Fecal neutral steroids were fractionated by high performance liquid chromatography (HPLC) into three major fractions: 5 beta-H, 3-keto steroids; 5 beta-H, 3 beta-hydroxy steroids; and 5 alpha-H and delta 5-3 beta-hydroxy steroids. This separation was achieved in about 10 minutes, with greater than 97% recovery of standards in each fraction. Gas-liquid chromatographic quantitation of fecal steroids fractionated by either HPLC or thin-layer chromatography gave nearly identical results. A method using both C18 reverse phase and silica HPLC to purify radiolabeled sterols is also described

Review of Androgenic Anabolic Steroid Use

2001-07-31

An area that has been overlooked within personnel security evaluations is employee use of androgenic-anabolic steroids (AAS). Current drug testing within the federal government does not include testing for anabolic steroids, and the difficulties to implement such testing protocols-not to mention the cost involved-make AAS testing highly improbable. The basis of this report is to bring to the forefront the damage that anabolic steroids can cause from both a physical and a psychological standpoint. Most individuals who use AASs do so to increase their muscle mass because they wish to gain some type of competitive edge during athletic competition or they wish to enhance their physical features for self-satisfaction and self-esteem (i.e., body building). Security officers are one group of men who often take high doses of anabolic steroids, according to the Second Report of the Senate Standing Committee (1990). The negative psychological characteristics for AAS use is extensive and includes prominent hostility, aggressiveness, irritability, euphoria, grandiose beliefs, hyperactivity, reckless behavior, increased sexual appetite, unpredictability, poor impulse control, mood fluctuations, and insomnia. The drug may invoke a sense of power and invincibility (Leckman and Scahill, 1990). Depressive symptoms, such as anhedonia, fatigue, impaired concentration, decreased libido, and even suicidality (Pope and Katz, 1992) have been noted with steroid withdrawal. It appears that long-term users of AAS experience similar characteristics as other substance abusers (i.e., craving, dependence, and withdrawal symptoms).

Homicide and Associated Steroid Acute Psychosis: A Case Report

Full Text Available We report the case of an old man treated with methylprednisolone for chronic lymphoid leukemia. After two months of treatment, he declared an acute steroid psychosis and beat his wife to death. Steroids were stopped and the psychotic symptoms subsided, but his condition declined very quickly. The clinical course was complicated by a major depressive disorder with suicidal ideas, due to the steroid stoppage, the leukemia progressed, and by a sudden onset of a fatal pulmonary embolism. This clinical case highlights the importance of early detection of steroid psychosis and proposes, should treatment not be stopped, a strategy of dose reduction combined with a mood stabilizer or antipsychotic treatment. In addition have been revised the risks of the adverse psychiatric effects of steroids.

Sampling of illicit drugs for quantitative analysis--part II. Study of particle size and its influence on mass reduction.

Bovens, M; Csesztregi, T; Franc, A; Nagy, J; Dujourdy, L

2014-01-01

The basic goal in sampling for the quantitative analysis of illicit drugs is to maintain the average concentration of the drug in the material from its original seized state (the primary sample) all the way through to the analytical sample, where the effect of particle size is most critical. The size of the largest particles of different authentic illicit drug materials, in their original state and after homogenisation, using manual or mechanical procedures, was measured using a microscope with a camera attachment. The comminution methods employed included pestle and mortar (manual) and various ball and knife mills (mechanical). The drugs investigated were amphetamine, heroin, cocaine and herbal cannabis. It was shown that comminution of illicit drug materials using these techniques reduces the nominal particle size from approximately 600 μm down to between 200 and 300 μm. It was demonstrated that the choice of 1 g increments for the primary samples of powdered drugs and cannabis resin, which were used in the heterogeneity part of our study (Part I) was correct for the routine quantitative analysis of illicit seized drugs. For herbal cannabis we found that the appropriate increment size was larger. Based on the results of this study we can generally state that: An analytical sample weight of between 20 and 35 mg of an illicit powdered drug, with an assumed purity of 5% or higher, would be considered appropriate and would generate an RSDsampling in the same region as the RSDanalysis for a typical quantitative method of analysis for the most common, powdered, illicit drugs. For herbal cannabis, with an assumed purity of 1% THC (tetrahydrocannabinol) or higher, an analytical sample weight of approximately 200 mg would be appropriate. In Part III we will pull together our homogeneity studies and particle size investigations and use them to devise sampling plans and sample preparations suitable for the quantitative instrumental analysis of the most common illicit

Impact of use of alcohol and illicit drugs by AIDS patients on adherence to antiretroviral therapy in Bahia, Brazil.

Use of alcohol and illicit drugs is a common finding among HIV-infected individuals, but there are many open questions about its impact on adherence to antiretroviral therapy and virological outcomes. Our study aimed to evaluate the impact of the use of alcohol and illicit drugs on the adherence to antiretroviral therapy (ART) among patients starting ART in Salvador, Brazil. We followed up 144 AIDS patients initiating ART for a 6-month period. At baseline, they were interviewed about demographics, behavior, and use of illicit drugs and alcohol. All of them had HIV-1 RNA plasma viral load and CD4(+)/CD8(+) cells count measured before starting therapy. After 60 days of treatment they were asked to answer a new questionnaire on adherence to ART. All patients were monitored during the following months, and new CD4(+) cell count/HIV-1 RNA plasma viral load determinations were performed after 6 months of therapy. Optimal adherence to therapy was defined by self-reported questionnaire, by 95% use of prescribed drug doses, and by using plasma HIV-1 RNA viral load as a biological marker. A total of 61 (42.4%) patients reported alcohol use, 7 (4.9%) used illicit drugs, and 17 (11.8%) used both alcohol and illicit drugs. Being in a steady relationship was protective to nonadherence (95% CI: 0.18-0.84). Missing more than two medical visits was also associated with a 68% higher likelihood of nonadherence (95% CI: 0.10-1.02). After logistic regression we detected a higher risk of nonadherence for patients declaring use of alcohol plus illicit drugs (odds ratio=6.0; 95% CI: 1.78-20.28) or high-intensity use of alcohol (odds ratio=3.29; 95% CI: 1.83-5.92). AIDS patients using alcohol and/or illicit drugs are socially vulnerable, and need specific and flexible programs, combining mental health care, harm reduction strategies, and assisted drug therapy to maximize the chances of successful use of ART.

Illicit drugs and the media: models of media effects for use in drug policy research.

Science.gov (United States)

Lancaster, Kari; Hughes, Caitlin E; Spicer, Bridget; Matthew-Simmons, Francis; Dillon, Paul

2011-07-01

Illicit drugs are never far from the media gaze and although identified almost a decade ago as 'a new battleground' for the alcohol and other drug (AOD) field there has been limited research examining the role of the news media and its effects on audiences and policy. This paper draws together media theories from communication literature to examine media functions. We illustrate how each function is relevant for media and drugs research by drawing upon the existing literature examining Australian media coverage during the late 1990s of escalating heroin-related problems and proposed solutions. Media can influence audiences in four key ways: by setting the agenda and defining public interest; framing issues through selection and salience; indirectly shaping individual and community attitudes towards risk; and feeding into political debate and decision making. Each has relevance for the AOD field. For example, media coverage of the escalating heroin-related problems in Australia played a strong role in generating interest in heroin overdoses, framing public discourse in terms of a health and/or criminal issue and affecting political decisions. Implications AND CONCLUSION: Media coverage in relation to illicit drugs can have multifarious effects. Incorporating media communication theories into future research and actions is critical to facilitate understanding of the short- and long-term impacts of media coverage on illicit drugs and the avenues by which the AOD field can mitigate or inform future media debates on illicit drugs. © 2010 Australasian Professional Society on Alcohol and other Drugs.

Although illicit exchange has also been an organized, silent, and ever-present response to harsh economic crisis, only protest and social movements have captured scholars’ attention. In order to fill this void, this paper analyzes the emergence of illegal markets under situations of social breakdown. I claim that an illicit market emerging under socio-economic crisis conditions might be understood as the result of a constant valuation process and the intervention of what Herbert Mead called “...

Do mollusks use vertebrate sex steroids as reproductive hormones? II. Critical review of the evidence that steroids have biological effects.

Science.gov (United States)

Scott, Alexander P

2013-02-01

In assessing the evidence as to whether vertebrate sex steroids (e.g. testosterone, estradiol, progesterone) have hormonal actions in mollusks, ca. 85% of research papers report at least one biological effect; and 18 out of 21 review papers (published between 1970 and 2012) express a positive view. However, just under half of the research studies can be rejected on the grounds that they did not actually test steroids, but compounds or mixtures that were only presumed to behave as steroids (or modulators of steroids) on the basis of their effects in vertebrates (e.g. Bisphenol-A, nonylphenol and sewage treatment effluents). Of the remaining 55 papers, some can be criticized for having no statistical analysis; some for using only a single dose of steroid; others for having irregular dose-response curves; 40 out of the 55 for not replicating the treatments; and 50 out of 55 for having no within-study repetition. Furthermore, most studies had very low effect sizes in comparison to fish-based bioassays for steroids (i.e. they had a very weak 'signal-to-noise' ratio). When these facts are combined with the fact that none of the studies were conducted with rigorous randomization or 'blinding' procedures (implying the possibility of 'operator bias') one must conclude that there is no indisputable bioassay evidence that vertebrate sex steroids have endocrinological or reproductive roles in mollusks. The only observation that has been independently validated is the ability of estradiol to trigger rapid (1-5 min) lysosomal membrane breakdown in hemocytes of Mytilus spp. This is a typical 'inflammatory' response, however, and is not proof that estradiol is a hormone - especially when taken in conjunction with the evidence (discussed in a previous review) that mollusks have neither the enzymes necessary to synthesize vertebrate steroids nor nuclear receptors with which to respond to them.

Illicit trafficking of radioactive material in Hungary

International Nuclear Information System (INIS)

Golder, I.

1996-01-01

Hungary, due to its geographical location is a convenient region for illegal transit of nuclear material between source and target countries. In recent years nine cases have became known and altogether 21.7 kg depleted, 4.6 kg natural, and 2.5 kg low enriched uranium have been confiscated. A brief summary is given of possible origin of the illicitly transported radioactive material. The most important elements of the security of sources including the national and accounting system of radioactive material and the intervention plans are discussed. (author)

Response to Illicit Trafficking of Radioactive Materials

International Nuclear Information System (INIS)

2010-01-01

Two response paths are discussed in the presentation. Reactive response follows when an alarm of a border monitor goes off or a notification is received about an incident involving or suspected to involve radioactive materials. The response can also be the result of the finding of a discrepancy between a customs declaration form and the corresponding actual shipment. Proactive response is undertaken upon receipt of intelligence information suggesting the illicit trafficking of radioactive materials, notification about the discovery of non-compliance with transport regulations or if discrepancies are found in an inventory of radioactive materials.

Diagnostic criteria for preclinical Cushing's syndrome (PCS) were reported in 1996. However, requirement of postoperative steroid hormone replacement is still controversial issue. In this study, we observed recent surgical cases retrospectively and evaluate the use of postoperative steroid hormone replacement. Eighteen patients with PCS underwent surgery from 1997 to 2007 in Jikei University Hospital. Thirteen of them received postoperative steroid hormone replacement. We investigated preoperative hormone activity by 131 I-adosterol scintigraphy and suppression of adrenocorticotropic hormone (ACTH) and evaluated the requirement of postoperative steroid hormone replacement. Preoperative serum cortisol was normal range in all patients. Serum ACTH was suppressed in 10 of them (56%). In 131 I-adosterol scintigraphy, accumulation in ipsilateral side was observed in all patients. Accumulation in contralateral side was observed in 13 patients whose serum ACTH had tendency to be suppressed. Mean period of steroid hormone replacement was 19.8 weeks. Patients with lower preoperative ACTH tended to require longer period until withdrawal of steroid hormone replacement. In addition, patients received steroid hormone replacement with higher starting dose significantly required longer period. Three of them had complications during tapering of steroid hormone. Postoperative adrenal insufficiency is important issue as postoperative management of PCS patients whose function of contralateral adrenal or pituitary gland is suppressed. 131 I-adosterol scintigraphy and preoperative serum ACTH were important factors to evaluate the requirement of postoperative steroid hormone replacement. Especially, patients with low preoperative serum ACTH tended to require long duration of postoperative steroid hormone replacement. On the other hand, patients with accumulation of contralateral side in 131 I-adosterol scintigraphy and without suppression of serum ACTH may not require steroid hormone

The IAEA's Illicit Trafficking Database Programme

2001-01-01

Full text: As part of its overall programme on nuclear material security, the IAEA has since 1995 maintained a database of incidents of trafficking in nuclear materials and other radioactive sources. The Illicit Trafficking Database Programme (ITDP) is intended to assist Member States by alerting them to current incidents, by facilitating exchange of reliable, detailed information about incidents, and by identifying any common threads or trends that might assist States in combating illicit trafficking. The ITDP also seeks to better inform the public by providing basic information to the media concerning illicit trafficking events. Approximately 70 States have joined this programme for collecting and sharing information on trafficking incidents. Reporting States have the opportunity to designate what information may be shared with other States and what may be shared with the public. In cases where the IAEA's first information about a possible incident comes from news media or other open sources rather than from a State notification, the information first is evaluated, and then, if warranted, the relevant State or States are contacted to request confirmation or clarification of an alleged incident. During 2000, as a result of experience gained working with information on illicit nuclear trafficking, the IAEA developed of a flexible and comprehensive new database system. The new system has an open architecture that accommodates structured information from States, in-house information, open-source articles, and other information sources, such as pictures, maps and web links. The graphical user interface allows data entry, maintenance and standard and ad-hoc reporting. The system also is linked to a Web-based query engine, which enables searching of both structured and open-source information. For the period 1 January 1993 through 31 March 2001, the database recorded more than 550 incidents, of which about two-thirds have been confirmed by States. (Some of these

2013-07-01

Full Text Available Introduction: Despite various formal limitations, an increasing number of opioid users, especially those stabilised in substitution therapy, travel abroad, away from their permanent residence to neighbouring and remote countries on other continents. Drug users are particularly at risk to get infected with hepatitis A, B, C and HIV during travelling.The main objectives of the study were to identify and determine the frequency of potential travel-related risk behaviour, such as illicit drug use, sharing of injecting equipment, unprotected sex, involvement in criminal activities and the extent of risk in illicit drug users, included in the programmes of the Centers for Prevention and Treatment of Drug Addiction in Slovenia.Methods: The study was carried out in two phases. The first phase included semi-structured interviews conducted in a group of drug users willing to participate in the study. Based on the analysis of transcripts and additional data, the original questionnaire Risky behaviour of illicit drug users during travels was developed and filled in anonymously and on a voluntary basis at the network of Centres for Prevention and Treatment of Drug Addiction. Univariate analysis between independent and dependent factors was conducted based on chi-square test and t-test for independent factors. Multivariate analysis of the impact of independent factors on the dependent factor was conducted based on binary logistic regression.Results: The questionnaire was filled out anonymously and voluntarily by 776 individuals in 14 Slovene centres for prevention and treatment of drug addiction. The results confirmed the first hypothesis that drug users travelling away from their permanent residence are more likely to share their injecting equipment, and engage in unprotected sex and in drug-related crime, and the second hypothesis stating that illegal drug users included in the substitution treatment programmes, who regularly use drugs at home, more often

Full Text Available BACKGROUND: Studies have documented high use of tobacco, alcohol and illicit drugs in patients with panic disorder (PD. The comorbid substance use disorders worsen the prognosis of mood and anxiety disorders. The respiratory subtype (RS of PD seems to represent a more severe and distinct form of this disorder associated with higher familial history of PD and more comorbidity with other anxiety disorders. OBJECTIVES: Describe the patterns of tobacco, alcohol or illicit drug use in PD patients, and also to ascertain if patients with the RS use these substances more than those of the non-respiratory subtype. METHODS: This is a cross-sectional study with 71 PD patients. The Alcohol Use Disorders Identification Test and Fagerstrom Tobacco Questionnaire were used in the evaluation. Patients with four or five respiratory symptoms were classified in the RS, the remaining patients were classified as non-respiratory subtype. RESULTS: In our sample 31.0% were smokers, 11.3% were hazardous alcohol users and none of them was using illicit drugs. There were no differences between the respiratory and non-respiratory subtypes regarding the use of tobacco, alcohol, cannabis, cocaine, stimulants and hallucinogens. DISCUSSION: The RS was not correlated to the use of tobacco, alcohol and illicit drugs. Additional epidemiological and clinical studies focusing the relationship between PD and substance use are warranted.

Recent observations on the steroid synthetic capability within the brain open the possibility that benzodiazepines may influence steroid synthesis in nervous tissue through interactions with peripheral-type benzodiazepine recognition sites, which are highly expressed in steroidogenic cells and associated with the outer mitochondrial membrane. To examine this possibility nine molecules that exhibit a greater than 10,000-fold difference in their affinities for peripheral-type benzodiazepine bin...

Steroid dysregulation and stomatodynia (burning mouth syndrome).

Science.gov (United States)

Woda, Alain; Dao, Thuan; Gremeau-Richard, Christelle

2009-01-01

Stomatodynia ( burning mouth syndrome) is characterized by a spontaneous, continuous burning pain felt in the oral mucosa typically of anxiodepressive menopausal women. Because there is no obvious organic cause, it is considered a nonspecific pain. This Focus Article proposes a hypothesis based on the following pathophysiological cascade: chronic anxiety or post traumatic stress leads to a dysregulation of the adrenal production of steroids. One consequence is a decreased or modified production of some major precursors for the neuroactive steroid synthesis occurring in the skin, mucosa, and nervous system. At menopause, the drastic fall of the other main precursor supply , the gonadal steroids, leads to a brisk alteration of the production of neuroactive steroids. This results in neurodegenerative alterations of small nerves fibers of the oral mucosa and /or some brain areas involved in oral somatic sensations. These neuropathic changes become irreversible and precipitate the burning pain, dysgeusia, and xerostomia associated with stomatodynia, which all involve thin nerve fibers.

Corticosteroids used as immunosuppressants to prevent acute rejection (AR) and graft loss (GL) following kidney transplantation are associated with serious cardiovascular and other adverse events. Evidence from short-term randomized controlled trials suggests that many patients on a tacrolimus-based immunosuppressant regimen can withdraw from steroids without increased AR or GL risk. To measure the long-term tradeoff between GL and adverse events for a heterogeneous-risk population and determine the optimal timing of steroid withdrawal. A discrete event simulation was developed including, as events, AR, GL, myocardial infarction (MI), stroke, cytomegalovirus, and new onset diabetes mellitus (NODM), among others. Data from the United States Renal Data System were used to estimate event-specific parametric regressions, which accounted for steroid-sparing regimen (avoidance, early 7-d withdrawal, 6-mo withdrawal, 12-mo withdrawal, and maintenance) as well as patients' demographics, immunologic risks, and comorbidities. Regression-equation results were used to derive individual time-to-event Weibull distributions, used, in turn, to simulate the course of patients over 20 y. Patients on steroid avoidance or an early-withdrawal regimen were more likely to experience AR (45.9% to 55.0% v. 33.6%, P events and other outcomes with no worsening of AR or GL rates compared with steroid maintenance.

2014-01-01

Background Following a legal agreement with the European Union (EU), Philip Morris International (PMI) commissions a yearly report (‘Project Star’, PS) on the European illicit cigarette trade from KPMG, the global accountancy firm. Methods Review of PS 2010 report. Comparison with data from independent sources including a 2010 pan-European survey (N=18 056). Findings Within PS, data covering all 27 EU countries are entered into a model. While the model itself seems appropriate, concerns are identified with the methodologies underlying the data inputs and thus their quality: there is little transparency over methodologies; interview data underestimate legal non-domestic product partly by failing to account for legal cross-border sales; illicit cigarette estimates rely on tobacco industry empty pack surveys which may overestimate illicit; and there is an over-reliance on data supplied by PMI with inadequate external validation. Thus, PMI sales data are validated using PMI smoking prevalence estimates, yet PMI is unable to provide sales (shipment) data for the Greek islands and its prevalence estimates differ grossly from independent data. Consequently, comparisons with independent data suggest PS will tend to overestimate illicit cigarette levels particularly where cross-border shopping is frequent (Austria, Finland, France) and in Western compared with Eastern European countries. The model also provides data on the nature of the illicit cigarette market independent of seizure data suggesting that almost a quarter of the illicit cigarette market in 2010 comprised PMI's own brands compared with just 5% counterfeited PMI brands; a finding hidden in PMI's public representation of the data. Conclusions PS overestimates illicit cigarette levels in some European countries and suggests PMI's supply chain control is inadequate. Its publication serves the interests of PMI over those of the EU and its member states. PS requires greater transparency, external scrutiny and

Illicit drugs: contaminants in the environment and utility in forensic epidemiology.

The published literature that addresses the many facets of pharmaceutical ingredients as environmental contaminants has grown exponentially since the 1990s. Although there are several thousand active ingredients used in medical pharmaceuticals worldwide, illicit drug ingredients (IDIs) have generally been excluded from consideration. Medicinal and illicit drugs have been treated separately in environmental research even though they pose many of the same concerns regarding the potential for both human and ecological exposure. The overview presented here covers the state of knowledge up until mid-2010 regarding the origin, occurrence, fate, and potential for biological effects of IDIs in the environment. Similarities exist with medical pharmaceuticals, particularly with regard to the basic processes by which these ingredients enter the environment--excretion of unmetabolized residues (including via sweat), bathing, disposal, and manufacturing. The features of illicit drugs that distinguish them from medical pharmaceuticals are discussed. Demarcations between the two are not always clear, and a certain degree of overlap adds additional confusion as to what exactly defines an illicit drug; indeed, medical pharmaceuticals diverted from the legal market or used for non-medicinal purposes ar also captured in discussions of illicit drugs. Also needing consideration as par tof the universe of IDIs are the numerous adulterants and synthesis impurities often encountered in these very impure preparations. many of these extraneous chemicals have high biological activity themselves. In contract to medical pharmaceuticals, comparatively little is know about the fate and effects of IDIs in the environment. Environmental surveys for IDIs have revealed their presence in sewage wastewaters, raw sewage sludge and processed sludge (biosolids), and drinking water. Nearly nothing is known, however, regarding wildlife exposure to IDIs, especially aquatic exposure such as indicated by

2014-09-01

We sought to measure the prevalence of illicit drug use in our obstetric population, to identify the drugs being used, and to determine whether a modified version of the 4Ps Plus screening tool could serve as an initial screen. In this prospective study, urine samples of 200 unselected patients presenting for initiation of prenatal care in a Wisconsin private practice were analyzed for evidence of the use of illicit drugs. Of 200 patients, 26 (13%) had evidence of drugs of abuse in their urine samples. Marijuana (7%) and opioids (6.5%) were the most commonly identified drugs. Adding 5 questions about drug or alcohol use to the obstetric intake questionnaire proved sensitive in identifying patients with high risks of having a positive drug screen. The rate of drug use in our low-risk population was higher than expected and may reflect increasing rates of drug use across the United States. Enhanced screening should be performed to identify patients using illicit drugs in pregnancy to improve their care. Medical centers and communities may benefit from periodic testing of their community prevalence rates to aid in appropriate care planning. Copyright © 2014 Mosby, Inc. All rights reserved.

Comparisons between the attitudes of student nurses and other health and social care students toward illicit drug use: An attitudinal survey.

Harling, Martyn R

2017-01-01

In the context of a recent emphasis on compassion in the delivery of health care, the current study set out to measure the attitudes of different groups of health and social care students toward illicit drug users. Previous research has identified variations in the attitudes of different groups of health and social care professionals toward working with illicit drug users. Nurses, in particular, have been reported as holding moralistic or stereotypical views of illicit drug users. However, few studies have measured the attitudes of student nurses or compared their attitudes to other health and social care students. This article describes the use of a bespoke attitude scale to measure the attitudes of cohorts of student nurses, clinical psychology trainees, health and social care, social work and midwifery students at the start of their course (N=308). Results indicated that student nurses had the least tolerant attitudes, reinforcing the need for a specific educational focus on working with illicit drug users in nurse education. Variations between student groups indicate that Interprofessional Education can provide an opportunity to improve attitudes toward illicit drug users, particularly amongst student nurses.

Parasites and steroid hormones: corticosteroid and sex steroid synthesis, their role in the parasite physiology and development.

Directory of Open Access Journals (Sweden)

Marta C. Romano

2015-06-01

Full Text Available In many cases parasites display highly complex life cycles that include establishment of the larva or adults within host organs, but even in those that have only one host reciprocal intricate interactions occur. A bulk of evidence indicates that steroid hormones influence the development and course of parasitic infections, the host gender susceptibility to the infection and the associate differences in immunological response are good examples of the host-parasite interplay. However, the capacity of these organisms to synthesize their own steroidogenic hormones still has more questions than answers. It is now well known that many parasites synthesize ecdysteroids, but limited information is available on sex steroid and corticosteroid synthesis. This review intends to summarize some of the existing information in the field. In many but not all parasitosis the host hormonal environment determines the susceptibility, the course and severity of parasite infections. In most cases the infection disturbs the host environment, and activate immune responses that finally affect the endocrine system. Furthermore, sex steroids and corticosteroids may also directly modify the parasite reproduction and molting. Available information indicates that parasites synthesize some steroid hormones like ecdysteroids and sex steroids and the presence and activity of related enzymes have been demonstrated. More recently, the synthesis of corticosteroid like compounds has been shown in Taenia solium and tapeworms and in Taenia crassiceps WFU cysticerci. Deeper knowledge of the endocrine properties of parasites will contribute to understand their reproduction and reciprocal interactions with the host, and also may contribute to design tools to combat the infection in some clinical situations.

Despite the growing interest on the presence of illicit drugs in freshwater ecosystems, just recently the attention has been focused on their potential toxicity towards non-target aquatic species. However, these studies largely neglected the effects induced by exposure to complex mixtures of illicit drugs, which could be different compared to those caused by single psychoactive molecules. This study was aimed at investigating the genetic damage induced by a 14-day exposure to a realistic mixture of the most common illicit drugs found in surface waters worldwide (cocaine, benzoylecgonine, amphetamine, morphine and 3,4-methylenedioxymethamphetamine) on the zebra mussel (Dreissena polymorpha). The mixture caused a significant increase of DNA fragmentation and triggered the apoptotic process and micronuclei formation in zebra mussel hemocytes, pointing out its potential genotoxicity towards this bivalve species.

We assessed the potential for harmful messages in online advertisements targeted to youth, using the example of the Canadian "Light It Up" marketing campaign from a large sports corporation. We undertook a cluster randomized controlled trial of 20 secondary school classes in Montreal, Canada. Classes were randomly allocated to view a "Light It Up" advertisement (n = 205) or a neutral comparison advertisement (n = 192). The main outcome measures were self-reports of illicit drug messages in the advertisements. Of the students, 22.9% reported that the "Light It Up" advertisement contained illicit drug messages compared with 1.0% for the comparison advertisement (relative risk, 22.0; 95% confidence interval, 6.5-74.9). Although meant to promote sports, youth in this study believed that the "Light It Up" advertisement was related to illicit drugs. The campaign illustrates how advertisements may inadvertently market unwanted behaviors to children. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

Radioimmunoassay (RIA) technique of steroid hormones in the laying hens, Gallus domesticus

International Nuclear Information System (INIS)

Ramli bin Abdullah

1990-01-01

The principle of radioimmunoassay (RIA) has been applied to many organic compounds of biological interest. In this work, commercially available antisera developed for various steroid hormones were used in the analysis of steroid hormones in the laying hens. The RIA procedure for plasma steroid hormones was divided into three phases: sample preparation, incubation of the antibody-3H-steroid complex with prepared samples and a standard curve and separation of antibody bound 3H-steroid from free 3H-steroid. Results showed that it is possible to use commercially available antiserum source for the determination of steroid hormones in this species. This approach has the advantage of savings in both time and money, by eliminating time losses in screening potential animals producing steroid antiserum and the costs of maintaining these animals

Endocrinology of sex steroid hormones and cell dynamics in the periodontium.

Science.gov (United States)

Mariotti, Angelo; Mawhinney, Michael

2013-02-01

Numerous scientific studies assert the existence of hormone-sensitive periodontal tissues. Tissue specificity of hormone localization, identification of hormone receptors and the metabolism of hormones are evidence that periodontal tissues are targets for sex steroid hormones. Although the etiologies of periodontal endocrinopathies are diverse, periodontal pathologies are primarily the consequence of the actions and interactions of sex steroid hormones on specific cells found in the periodontium. This review provides a broad overview of steroid hormone physiology, evidence for the periodontium being a target tissue for sex steroid hormones and theories regarding the roles of sex steroid hormones in periodontal pathogenesis. Using this information, a teleological argument for the actions of steroid hormones in the periodontium is assessed.

To assess the prevalence and different types of violence experienced by women prisoners in Brazil and the effects of violence on women's depression and illicit drug use. Participants (N=377) were incarcerated women from a state prison in a northeastern city of Brazil. Multivariate logistic regression models (adjusted for age, education, partner status, prison history, drug related offense, and sentencing status) were used to assess associations between each type of violence (physical abuse, sexual abuse, and life threats) and each outcome variable: recent depression and illicit drug use. The majority of participants (87%) reported experiencing some type of violence in their lifetime, including physical violence (83%), sexual victimization (36%), and threats on their life (29%.) Sexual violence was significantly related to both recent depression (Odds Ratio (OR)=2.8; 95% Confidence Interval (CI)=1.4-5.3) and recent substance use (OR=2.7; 95% CI=1.6-4.4) in adjusted models. Experiences of life threats were also significantly associated with illicit drug use (OR=2.2; 95% CI: 1.3-3.7), as was physical violence (OR=2.4; 95% CI: 1.2-4.9); however, neither of these latter two violence variables were significantly associated with depression. Reports of lifetime violence victimization among this incarcerated sample of women were extremely prevalent and relevant to women's depression and illicit drug use. Prison efforts to address women's depression and illicit drug use may be most effective by incorporating aspects related to women's history of victimization, especially given the high rates of violence experienced by women in this sample.

Full Text Available Abstract Thailand has traditionally pursued an aggressive enforcement-based anti-illicit drug policy in an effort to make the country "drug-free." In light of this ongoing approach, we sought to assess impacts of enforcement on drug use behaviors among a cohort of injection drug users (IDU in Thailand. We examined drug use patterns among IDU participating in a cross-sectional study conducted in Bangkok (n = 252. Participants were asked to provide data regarding patterns of drug use in the previous six months, including types of drugs consumed, method of consumption, frequency of use, and weekly income spent on drugs. We also conducted bivariate analyses to identify a possible effect of a reported increase in police presence on measures of drug use and related risk behaviors among study participants. One hundred fifty-five (61.5% individuals reported injection heroin use and 132 (52.4% individuals reported injection midazolam use at least daily in the past six months. Additionally, 86 (34.1% individuals reported at least daily injection Yaba and Ice (i.e., methamphetamine use. Participants in our study reported high levels of illicit drug use, including the injection of both illicit and licit drugs. In bivariate analyses, no association between increased police presence and drug use behaviors was observed. These findings demonstrate high ongoing rates of drug injecting in Thailand despite reports of increased levels of strict enforcement and enforcement-related violence, and raise questions regarding the merits of this approach.

Full Text Available Free radical levels can be higher than the level of endogenous antioxidants in the body so that uncomfortable conditions in the body of dairy goats could happen. To anticipate this uncomfortable conditions will be given feed supplement (FS as source of antioxidants (AOX. FS contain mixture pineapple rind meal and antioxidant minerals (AOXM each 25 ppm Zn and 10 ppm Cu. This experiment was carried out to investigate the effect of feed supplements as antioxidant source on milk quality of dairy goats. Sixteen Etawah dairy goats in the second lactation were used in the experiment that conducted using randomized block design with 4 treatments and 4 replicates. The treatments were R0 (grass + concentrate, R1 (R0 + FS containing 0.04 % AOX, R2 (R0 + FS containing 0.06% AOX, R3 (R0 + FS containing 0.08 % AOX. The data collected were analyzed using Anova. The result of phytochemicals analysis indicated that feed supplement contained flavonoid, polyphenols, sesqiuterpen, mopnoterpen, steroids, quinones and saponins. The results of study showed that there were difference (p0.05 on milk yield, milk fat, milk protein and milk antioxidant. The conclusion of this study was the feed supplements containing 0.08 AOX produced the best response to milk quality of dairy goats.

A tagged neutron inspection system has been used for the detection of explosive and illicite drugs. Simulant of the RDX explosive was measured in different environments and its gamma ray spectra were compared with the gamma ray spectra of benign materials like paper, sugar and rise. "Fingerprint" of the RDX simulant was found by detecting the nitrogen as well as by making the triangle plot which coordinates show the carbon and oxygen content and density. Density was obtained by measuring the intensity of the transmited tagged neutrons. Hence, the presence of the simulant can be confirmed by using two different methods. The possibility of using the triangle plot for detection of illicit drugs like heroin, cocain and marihuana is also discused.

A portable capillary electrophoresis instrument with dual capacitively coupled contactless conductivity detection (C 4 D) was used to determine the inorganic ionic profiles of three pharmaceutical samples and precursors of two illicit drugs (contemporary samples of methylone and para-methoxymethamphetamine). The LODs ranged from 0.10 μmol/L to 1.25 μmol/L for the 10 selected cations, and from 0.13 μmol/L to 1.03 μmol/L for the eight selected anions. All separations were performed in less than 6 min with migration times and peak area RSD values ranging from 2 to 7%. The results demonstrate the potential of the analysis of inorganic ionic species to aid in the identification and/or differentiation of unknown tablets, and real samples found in illicit drug manufacture scenarios. From the resulting ionic fingerprint, the unknown tablets and samples can be further classified. © 2016 American Academy of Forensic Sciences.

ITRAP. Illicit trafficking radiation detection assessment program

International Nuclear Information System (INIS)

Beck, P.

2001-02-01

Illicit trafficking in nuclear materials (nuclear criminality) has become more and more a problem, due to the circulation of the a high number of radioactive sources and the big amount of nuclear material, particularly, caused by the changes of the organisational infrastructures to supervise these material within the successor states of the former Soviet Union. The IAEA data base counts at present more than 300 verified cases. The endangering cased thereby ranges from possible health defect for the publication to terrorists activities and production of nuclear weapons. In addition to the primary criminal reasons the illegal deposal of radioactive sources as salvage, scrap and others show a further problem, which has lead to severe accidents and lethal effects in the past (e.g. Goiana, Mexiko). As the study ITRAP (Illicit Trafficking Radiation Assessment Program) can show, also in Austria the cases of partly considerable contaminated scrap transports from neighbouring countries exists. Some countries have already under taken countermeasures (e.g. Monitoring at the Finnish-Russian and German-Polish border, border monitoring in Italy). The International Atomic Energy Agency (IAEA) has reacted on this actual problem by setting up a new program to fight against nuclear criminality and has suggested a pilot study for the practical test of border monitoring systems. Aim of the study was to work out the technical requirements and the practicability of an useful monitoring system at border crossings. The results of the study will be offered by the IAEA to the member states as international recommendations for border monitoring systems. (author)

Although the use of nutritional supplements by adult athletes has been extensively studied, information on supplements consumption by adolescent athletes is still limited. The present study reports on the use of nutritional supplements contaminated with banned doping substances among 170 recreational adolescent athletes from eleven, randomly selected, gym centres, in Athens, Greece. Nutritional supplements consumption was reported by almost 60% of the study population, with proteins/amino acids and vitamins being the most popular. Nine per cent of the users were found to consume nutritional supplements contaminated with anabolic steroids, prohormones, selective androgen receptor modulators (SARMs) and aromatase inhibitors, all pharmacological substances with endocrine modulating properties not stated on the label. None of these individuals had previously consulted a physician or a nutritionist. A representative sample (ca 15%) of the protein/aminoacids and creatine preparations used by the study population were also tested and found free from doping substances. The majority (63%) of adolescents purchased products from the internet. In conclusion, exercising adolescents can have easy access to contaminated nutritional supplements and "black market" products, which could constitute a risk for public health. Low level of awareness and low involvement of medical care professionals among recreational adolescent athletes is also observed. Copyright © 2018 Elsevier Ltd. All rights reserved.

The origins of signaling by vertebrate steroids are not fully understood. An important advance was the report that an estrogen-binding steroid receptor [SR] is present in amphioxus, a basal chordate with a similar body plan as vertebrates. To investigate the evolution of estrogen-binding to steroid receptors, we constructed a 3D model of amphioxus SR complexed with estradiol. This 3D model indicates that although the SR is activated by estradiol, some interactions between estradiol and human ER{alpha} are not conserved in the SR, which can explain the low affinity of estradiol for the SR. These differences between the SR and ER{alpha} in the steroid-binding domain are sufficient to suggest that another steroid is the physiological regulator of the SR. The 3D model predicts that mutation of Glu-346 to Gln will increase the affinity of testosterone for amphioxus SR and elucidate the evolution of steroid-binding to nuclear receptors.

Sugammadex has steroid-encapsulating effect. This study was undertaken to assess whether the clinical efficacy of sugammadex was altered by the administration of steroids. Sixty patients between 18 and 60 years of age with the American Society of Anesthesiologists I-IV and undergoing elective direct laryngoscopy/biopsy were included in this study. Patients were assigned to two groups based on the intraoperative steroid use: those who received steroid (Group S) and who did not (Group C). After standard general anesthesia, patients were monitored with the train of four (TOF) monitoring. The preferred steroid and its dose, timing of steroid administration, and TOF value before and after sugammadex as well as the time to recovery (TOF of 0.9) were recorded. SPSS software version 17.0 was used for statistical analysis. There is no statistically significant difference between groups in terms of age, gender, preoperative medication use, and TOF ratio just before administering sugammadex. The reached time to TOF 0.9 after sugammadex administration was significantly shorter in Group S than Group C (P sugammadex as well as the dose of sugammadex in those who received prednisolone; time to TOF 0.9 was higher in prednisolone receivers as compared to dexamethasone receivers (P sugammadex was found, in contrast with what one expect. Further studies are required to determine the cause of this effect which is probably due to a potential interaction between sugammadex and steroids.

Full Text Available Abstract Background Despite the availability of antiretroviral therapy (ART, suboptimal treatment outcomes have been observed among HIV-seropositive illicit drug users. As there is an urgent need to improve responses to antiretroviral therapy among this population, we undertook this study to evaluate the role of physician experience on rates of plasma HIV-1 RNA suppression following initiation of ART. Methods Using data from a community-recruited cohort of HIV-positive illicit drug users, we used Cox proportional hazards regression to model the time to plasma viral HIV RNA Results Between May 1996 and December 2008, 267 individuals initiated ART among whom 227 (85% achieved a plasma HIV RNA Conclusions In this setting of universal HIV/AIDS care, illicit drug users with more experienced physicians exhibited faster rates of plasma viral load suppression. These findings argue for specialized services to help optimize HIV treatment outcomes among this population.

Context Comprehensive descriptions of substance use and abuse trajectories have been lacking in nationally representative samples of adolescents. Objective To examine the prevalence, age at onset, and sociodemographic correlates of alcohol and illicit drug use and abuse among US adolescents. Design Cross-sectional survey of adolescents using a modified version of the Composite International Diagnostic Interview. Setting Combined household and school adolescent samples. Participants Nationally representative sample of 10 123 adolescents aged 13 to 18 years. Main Outcome Measures Lifetime estimates of alcohol and illicit substance use and DSM-IV diagnoses of abuse, with or without dependence. Results By late adolescence, 78.2% of US adolescents had consumed alcohol, 47.1% had reached regular drinking levels defined by at least 12 drinks within a given year, and 15.1% met criteria for lifetime abuse. The opportunity to use illicit drugs was reported by 81.4% of the oldest adolescents, drug use by 42.5%, and drug abuse by 16.4%. The median age at onset was 14 years for alcohol abuse with or without dependence, 14 years for drug abuse with dependence, and 15 years for drug abuse without dependence. The associations observed by age, sex, and race/ ethnicity often varied significantly by previous stage of use. Conclusions Alcohol and drug use is common in US adolescents, and the findings of this study indicate that most cases of abuse have their initial onset in this important period of development. Prevention and treatment efforts would benefit from careful attention to the correlates and risk factors that are specific to the stage of substance use in adolescents. PMID:22474107

Transweb and trafficking in illicit nuclear materials: beyond the borders of physical security

International Nuclear Information System (INIS)

Ballard, J.D.; Dilger, F.

2005-01-01

Full text: Transweb is a developing threat assessment analytical protocol that uses real time GIS based assessments (a.k.a., GTA for GIS Threat Assessment) to better understand potential trafficking in illicit nuclear materials that may come from energy related sites and/or weapons production facilities. This is not a physical security protocol nor is this program a border check format like the DOE's Second Line of Defense which is designed to detect special nuclear fuels. Transweb is a tool that allows the user to look at surreptitious transportation pathways that may be used to move illicit nuclear materials after they have already breached traditional physical security barriers and allows for movement prediction and potential mitigation/intervention if they are not traveling on the highways or railways, traversing the waterways, or entering ports equipped with detecting equipment like that deployed in Second Line of Defense program. Transweb is for the real world, a world where physical security may be breached and the smugglers that capture these materials do not follow the most traveled highways, railways, or waterways in a given society. Transweb focuses on the less obvious transportation routes that may be the most likely ways that illicit nuclear materials will be transported. Thus this program offers an additional layer of security analysis not currently in use as physical protection or as border mitigation. (author)

Legal framework and practice to prevent and detect illicit trafficking of nuclear and radioactive materials

International Nuclear Information System (INIS)

Sembiring, D.

2001-01-01

Full text: Illicit trafficking in nuclear and radioactive materials in the country and across country borders has become serious problem from both nuclear proliferation and radiological hazard point of view. Prevention and detection of illicit trafficking in nuclear and radioactive materials is based on the regulation and procedure set up to ensure the control of the nuclear and radioactive materials throughout their life. Practically, prevention and detection measures in ensuring that nuclear materials do not become the subject of unauthorized use leading to illicit trafficking constitute (1) accounting for and (2) control of nuclear and radioactive materials and (3) physical protection of such materials. The Nuclear Energy Act No. 10 year 1997 is the legislative basis for the safety, including nuclear material accounting and control activities as well as security measures on the utilization of the nuclear and radioactive material in Indonesia. Government establishes Nuclear Energy Control Board (BAPETEN) as Regulatory Body having the task to control any activities using nuclear energy. The activities of control are implemented through regulation, licensing and inspection. The mission of the BAPETEN is to ensure adequate protection of the public health and safety, the common security, and the environmental in the peaceful uses of nuclear energy in Indonesia. To support this mission, BAPETEN has three principal regulatory functions: (1) establish regulation; (2) issue licenses and (3) inspect nuclear facilities. First component of regulatory function is establishing regulations, which define the capabilities that need to be satisfied by facility operators to protect against theft which in turn could lead to illicit trafficking. BAPETEN established the Decree on National System of Accounting for and Control of Nuclear Material (SSAC) based on the Agreement between Rl and IAEA on the Application of Safeguards in connection with NPT ratified in the Act No.8 year 1978

Lee, Min Hee

2004-01-01

To evaluate the efficacy of steroid injection into the subacromial bursa and biceps tendon sheath for painful shoulders and the usefulness of ultrasound-guided approach. Seventeen shoulders of twelve patients with shoulder pain and limited motion were included, and these patient were clinically diagnosed as a painful arc syndrome. Under ultrasound guidance, steroid injection was performed into the subacormial bursa (13 cases) and biceps tendon sheath (4 cases). In 7 cases, 1 mL of steroid was used while the remaining six patients received a mixture of 1 mL of steroid and 1 ml of lidocaine. Both shoulders of two patients received 0.5 mL of steroid. The location of needle and injection duration of fluid were continuously monitored, and complications such as leakage of steroid were recorded. Medical records were reviewed for the presence of pain relief and increasing range of motion following the injection. On ultrasonogram, the needle within the subacromial bursa and biceps tendon sheath was seen as a linear echogenic structure, and injected fluid was identified. There was neither the leakage of steroid injection nor any other complications. In 16 (94%) of 17 shoulders, there was decreased intensity of shoulder pain while increased range of motion was noted in three patients following the injection. Steroid injection into the subacormial bursa and biceps tendon sheath is effective in treating shoulder pain and limited range of motion of the shoulder, and ultrasound is useful guiding method.

Capillary electrophoresis: principles and applications in illicit drug analysis.

1996-02-09

Capillary electrophoresis, which appeared in the early 1980s, is now rapidly expanding into many scientific disciplines, including analytical chemistry, biotechnology and biomedical and pharmaceutical sciences. In capillary electrophoresis,electrokinetic separations are carried out in tiny capillaries at high voltages (10-30 kV), thus obtaining high efficiencies (N > 10(5)) and excellent mass sensitivities (down to 10(-18)-10(-20) moles). The main features of capillary electrophoresis are: versatility of application (from inorganic ions to large DNA fragments), use of different separation modes with different selectivity, extremely low demands on sample volume, negligible running costs, possibility of interfacing with different detection systems, ruggedness and simplicity of instrumentation. Capillary electrophoresis applications in forensic sciences have appeared only recently, but are now rapidly growing, particularly in forensic toxicology. The present paper briefly describes the basic principles of capillary electrophoresis, from both the instrumental and analytical points of view. Furthermore, the main applications in the analysis of illicit/controlled drugs in both illicit preparations and biological samples are presented and discussed (43 references). It is concluded that the particular separation mechanism and the high complementarity of this technique to chromatography makes capillary electrophoresis a new powerful tool of investigation in the hands of forensic toxicologists.

Illicit use of androgens and other hormones: recent advances.

Science.gov (United States)

Kanayama, Gen; Pope, Harrison G

2012-06-01

To summarize recent advances in studies of illicit use of androgens and other hormones. Androgens and other appearance-enhancing and performance-enhancing substances are widely abused worldwide. Three notable clusters of findings have emerged in this field in recent years. First, studies almost unanimously find that androgen users engage in polypharmacy, often ingesting other hormones (e.g., human growth hormone, thyroid hormones, and insulin), ergo/thermogenic drugs (e.g., caffeine, ephedrine, and clenbuterol), and classical drugs of abuse (e.g., cannabis, opiates, and cocaine). Second, reports of long-term psychiatric and medical adverse effects of androgens continue to accumulate. In cardiovascular research particularly, controlled studies have begun to supersede anecdotal evidence, strengthening the case that androgens (possibly acting synergistically with other abused drugs) may cause significant morbidity and even mortality. Third, it is increasingly recognized that androgen use may lead to a dependence syndrome with both psychological and physiological origins. Androgen dependence likely affects some millions of individuals worldwide, and arguably represents the least studied major class of illicit drug dependence. Given mounting evidence of the adverse effects of androgens and associated polypharmacy, this topic will likely represent an expanding area of research and an issue of growing public health concern.

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 investigate general and cannabis-specific parenting practices in relation to adolescent cannabis and other illicit drug use. Data were derived from the Dutch National School Survey on Substance Use among students (N=3209; aged 12-16 years) and one of their parents in 2011. Logistic regression analyses revealed that 1) parental cannabis use was significantly related to more adolescent lifetime and recent cannabis use, and 2) restrictive cannabis-specific parental rules were associated with less adolescent recent cannabis and lifetime use of other illicit drugs, even when controlled for sociodemographic factors, general parenting, adolescent tobacco use, and tobacco-specific parenting. In addition, no significant interaction was observed between parental cannabis use and cannabis-specific rules in their relation to adolescent cannabis and other illicit drug use, indicating that cannabis rules are evenly associated with adolescent drug use for families with and without parental cannabis experience. In addition to general parenting practices, restrictive cannabis-specific rules are related to lower adolescent cannabis and other illicit drug rates. Parents who ever used cannabis have children with a higher prevalence of cannabis use. However, their restrictive cannabis-specific rules are equally related to a lower chance of adolescent cannabis use. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Summary In the past several decades, the therapeutic use of anabolic androgenic steroids (AAS) has been overshadowed by illicit use of these drugs by elite athletes and a growing number of adolescents to enhance performance and body image. As with adults, AAS use by adolescents is associated with a range of behavioral effects, including increased anxiety and altered responses to stress. It has been suggested that adolescents, especially adolescent females, may be particularly susceptible to the effects of these steroids, but few experiments in animal models have been performed to test this assertion. Here we show that chronic exposure of adolescent female mice to a mixture of three commonly abused AAS (testosterone cypionate, nandrolone decanoate and methandrostenolone; 7.5 mg/kg/day for 5 days) significantly enhanced anxiety-like behavior as assessed by the acoustic startle response (ASR), but did not augment the fear-potentiated startle response (FPS) or alter sensorimotor gating as assessed by prepulse inhibition of the acoustic startle response (PPI). AAS treatment also significantly increased the levels of corticotropin releasing factor (CRF) mRNA and somal-associated CRF immunoreactivity in the central amygdala (CeA), as well as neuropil-associated immunoreactivity in the dorsal aspect of the anterolateral division of the bed nucleus of the stria terminalis (dBnST). AAS treatment did not alter CRF receptor 1 or 2 mRNA in either the CeA or the dBnST; CRF immunoreactivity in the ventral BNST, the paraventricular nucleus (PVN) or the median eminence (ME); or peripheral levels of corticosterone. These results suggest that chronic AAS treatment of adolescent female mice may enhance generalized anxiety, but not sensorimotor gating or learned fear, via a mechanism that involves increased CRF-mediated signaling from CeA neurons projecting to the dBnST.

Absorption spectra of six illicit drugs were measured by using the terahertz time-domain spectroscopy technique in the range 0.2-2.6 THz and then clustered with self-organization feature map (SOM) artificial neural network. After the network training process, the spectra collected at another time were identified successfully by the well-trained SOM network. An effective distance was introduced as a quantitative criterion to decide which cluster the new spectra were affiliated with.

Kuuranne, Tiia; Saugy, Martial; Baume, Norbert

2014-01-01

In the fight against doping, steroid profiling is a powerful tool to detect drug misuse with endogenous anabolic androgenic steroids. To establish sensitive and reliable models, the factors influencing profiling should be recognised. We performed an extensive literature review of the multiple factors that could influence the quantitative levels and ratios of endogenous steroids in urine matrix. For a comprehensive and scientific evaluation of the urinary steroid profile, it is necessary to define the target analytes as well as testosterone metabolism. The two main confounding factors, that is, endogenous and exogenous factors, are detailed to show the complex process of quantifying the steroid profile within WADA-accredited laboratories. Technical aspects are also discussed as they could have a significant impact on the steroid profile, and thus the steroid module of the athlete biological passport (ABP). The different factors impacting the major components of the steroid profile must be understood to ensure scientifically sound interpretation through the Bayesian model of the ABP. Not only should the statistical data be considered but also the experts in the field must be consulted for successful implementation of the steroidal module. PMID:24764553

Illicit drugs and their metabolites have recently been recognized as an emerging group of contaminants due to their potential ecotoxicological impact in aquatic ecosystems. To date, information on the occurrence of these compounds in the aquatic environment of China remains limited. In this study, we collected surface water samples from 36 rivers in north China that discharge into the Bohai Sea and north Yellow Sea and measured the concentrations of amphetamine-like compounds, ketamines, cocainics, and opioids. The occurrence and spatial patterns of these substances show significant differences between the rivers and regions. Two designer drugs, methamphetamine (METH) and ketamine (KET), were the most abundant compounds detected in the entire set of samples (detection frequency of 92 and 69 %). The concentrations of METH and KET ranged from illicit drugs consumed in China. The high concentrations of these illicit drugs and their metabolites were found in areas that have a high population density. The riverine input of total illicit drugs into the Bohai Sea and north Yellow Sea was estimated to be in the range of 684 to 1160 kg per year.

Background Amidst the rise of e-commerce, there has been a proliferation of illicit online pharmacies that threaten global patient safety by selling drugs without a prescription directly to the consumer. Despite this clear threat, little is known about the key risk characteristics, central challenges and current legal, regulatory and law enforcement responses. Sources of data A review was conducted of the English literature with search terms ‘online pharmacies’, ‘Internet pharmacies’, ‘cyber pharmacies’, ‘rogue pharmacies’, and ‘e-pharmacies’ using PubMed, JSTOR, and Google Scholar from 1999–2005. Areas of agreement Illicit online pharmacies are a rapidly growing public health threat and are characterized by a number of complex and interrelated risk factors. Areas of controversy Solutions are varied and are of questionable utility in the face of evolving technology that enables this form of transnational cybercrime. Growing points Legal, regulatory and technology solutions must address the entire illicit online pharmacy ecosystem in order to be effective. Areas timely for developing research There is a critical need to build international consensus, conduct additional research and develop technology to combat illicit online pharmacies. PMID:27151957

Wastewater analysis provides a non-intrusive way of measuring drug use within a population. We used this approach to determine daily use of conventional illicit drugs [cannabis, cocaine, methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA)] and emerging illicit psychostimulants (benzylpiperazine, mephedrone and methylone) in two consecutive years (2010 and 2011) at an annual music festival. Daily composite wastewater samples, representative of the festival, were collected from the on-site wastewater treatment plant and analysed for drug metabolites. Data over 2 years were compared using Wilcoxon matched-pair test. Data from 2010 festival were compared with data collected at the same time from a nearby urban community using equivalent methods. Conventional illicit drugs were detected in all samples whereas emerging illicit psychostimulants were found only on specific days. The estimated per capita consumption of MDMA, cocaine and cannabis was similar between the two festival years. Statistically significant (P popularity in music settings. Our study demonstrated that wastewater analysis can objectively capture changes in substance use at a music setting without raising major ethical issues. It would potentially allow effective assessments of drug prevention strategies in such settings in the future. © 2013 Australasian Professional Society on Alcohol and other Drugs.

Mobile phone use has increased dramatically and concurrent with rapid developments in mobile phone-based health interventions. The integration of text messaging interventions promises to optimise the delivery of care for persons with substance dependence with minimal disruption to clinical workflows. We conducted a systematic review to assess the acceptability, feasibility and clinical impact of text messaging interventions for persons with illicit drug and alcohol dependence. Studies were required to evaluate the use of text messaging as an intervention for persons who met Diagnostic and Statistical Manual of Mental Disorders, 4th edition criterion for a diagnosis of illicit drug and/or alcohol dependence. Authors searched for articles published to date in MEDLINE (pubmed.gov), the Cochrane Library, EMBASE, CINAHL, Google Scholar and PsychINFO. Eleven articles met the search criteria for this review and support the acceptability and feasibility of text messaging interventions for addressing illicit drug and alcohol dependence. Most studies demonstrated improved clinical outcomes, medication adherence and engagement with peer support groups. Text messaging interventions also intervened on multiple therapeutic targets such as appointment attendance, motivation, self-efficacy, relapse prevention and social support. Suggestions for future research are described, including intervention design features, clinician contact, privacy measures and integration of behaviour change theories. Text messaging interventions offer a feasible platform to address a range of substances (i.e. alcohol, methamphetamine, heroin and alcohol), and there is increasing evidence supporting further larger-scale studies.

Sex steroid-related candidate genes in psychiatric disorders.

Science.gov (United States)

Westberg, Lars; Eriksson, Elias

2008-07-01

Sex steroids readily pass the blood-brain barrier, and receptors for them are abundant in brain areas important for the regulation of emotions, cognition and behaviour. Animal experiments have revealed both important early effects of these hormones on brain development and their ongoing influence on brain morphology and neurotransmission in the adult organism. The important effects of sex steroids on human behaviour are illustrated by, for example, the effect of reduced levels of these hormones on sexual drive and conditions such as premenstrual dysphoric disorder, perimenopausal dysphoria, postpartum depression, postpartum psychosis, dysphoria induced by oral contraceptives or hormonal replacement therapy and anabolic steroid-induced aggression. The fact that men and women (as groups) differ with respect to the prevalence of several psychiatric disorders, certain aspects of cognitive function and certain personality traits may possibly also reflect an influence of sex steroids on human behaviour. The heritability of most behavioural traits, including personality, cognitive abilities and susceptibility to psychiatric illness, is considerable, but as yet, only few genes of definite importance in this context have been identified. Given the important role of sex steroids for brain function, it is unfortunate that relatively few studies so far have addressed the possible influence of sex steroid-related genes on interindividual differences with respect to personality, cognition and susceptibility to psychiatric disorders. To facilitate further research in this area, this review provides information on several such genes and summarizes what is currently known with respect to their possible influence on brain function.

Response to events involving the inadvertent movement or illicit trafficking of radioactive materials

2002-09-01

By international agreements, the movement of all radioactive materials within and between States should be subject to high standards of regulatory, administrative, safety and engineering controls to ensure that such movements are conducted in a safe and secure manner. In the case of nuclear materials, there are additional requirements for physical protection and accountability to ensure against threats of nuclear proliferation and to safeguard against any attempts at diversion. The results of the terrorist attacks of September 2001 emphasized the requirement for enhanced control and security of nuclear and radioactive materials. In this regard, measures are being taken to increase the global levels of physical protection and security for nuclear materials. Experience in many parts of the world continues to prove that movements of radioactive materials outside of the regulatory and legal frameworks continue to occur. Such movements may be either deliberate or inadvertent. Deliberate, illegal movements of radioactive materials, including nuclear material, for terrorist, political or illegal profit is generally understood to be illicit trafficking. The more common movements outside of regulatory control are inadvertent in nature. An example of an inadvertent movement might be the transport of steel contaminated by a melted radioactive source that was lost from proper controls. Such a shipment may present health and safety threats to the personnel involved as well as to the general public. States have the responsibility for combating illicit trafficking and inadvertent movements of radioactive materials. The IAEA co-operates with Member States and other international organizations in joint efforts to prevent incidents of illicit trafficking and inadvertent movements and to harmonize policies and measures by the provision of relevant advice through technical assistance and documents.

Drug use and abuse/dependence are stages of a complex drug habit. Most genetically informative models that are fit to twin data examine drug use and abuse/dependence independent of each other. This poses an interesting question: for a multistage process, how can we partition the factors influencing each stage specifically from the factors that are common to both stages? We used a causal-common-contingent (CCC) model to partition the common and specific influences on drug use and abuse/dependence. Data on use and abuse/dependence of cannabis, cocaine, sedatives, stimulants and any illicit drug was obtained from male and female twin pairs. CCC models were tested individually for each sex and in a sex-equal model. Our results suggest that there is evidence for additive genetic, shared environmental and unique environmental influences that are common to illicit drug use and abuse/dependence. Furthermore, we found substantial evidence for factors that were specific to abuse/dependence. Finally, sexes could be equated for all illicit drugs. The findings of this study emphasize the need for models that can partition the sources of individual differences into common and stage-specific influences.

A robust multi-residue method was developed for the analysis of a selection of pharmaceutical compounds, illicit drugs and personal care product bactericides in sediments and sludges. Human pharmaceuticals were selected for analysis in Scottish sewage sludge and freshwater sediments based on prescription, physico-chemical and occurrence data. The method was suitable for the analysis of the selected illicit drugs amphetamine, benzoylecgonine, cocaine, and methamphetamine, the pharmaceuticals atenolol, bendroflumethiazide, carbamazepine, citalopram, diclofenac, fluoxetine, ibuprofen, and salbutamol, and the bactericides triclosan and triclocarban in sewage sludge and freshwater sediment. The method provided an overall recovery of between 56 and 128%, RSDs of between 2 and 19% and LODs of between 1 and 50 ng g(-1). Using the methodology the human pharmaceuticals atenolol, carbamazepine and citalopram and the bactericides triclosan and triclocarban were detected in Scottish sewage sludge. The illicit drugs cocaine, its metabolite benzoylecgonine, amphetamine and methamphetamine were not detected in any of the samples analysed. Triclosan and triclocarban were present at the highest concentrations with triclocarban detected in all but one sample and showing a pattern of co-occurrence in both sludge and sediment samples.

Extracellular and intracellular steroid binding proteins

Steroid hormone binding proteins can be measured, after the removal of endogenous steroids, as specific complexes with radio-labelled hormones. In this study all the requirements for a quantitative determination of steroid hormone binding proteins are defined. For different methods, agargel electrophoresis, density gradient centrifugation, equilibrium dialysis and polyacrylamide electrophoresis have been evaluated. Agar electrophoresis at low temperature was found to be the simplest and most useful procedure. With this method the dissociation rates of high affinity complexes can be assessed and absolute binding protein concentrations can be determined. The dissociation rates of the oestradiol-oestrogen receptor complex and the R-5020-progestin receptor complex are low (1-2% per h run time.) In contrast, that of complexes between androgen receptor and dihydrotestosterone (17β-hydroxy-5α-androstan-3-one (DHT), progestin receptor and progesterone, corticosteroid binding globulin (CBG) and cortisol or progesterone and sex hormone binding globulin (SHBG) and DHT were hign (16-27% per h run time). Target tissue extracts (cytosols) contain, besides soluble tissue proteins, large amounts of plasma proteins. The extent of this plasma contamination can be determined by measuring the albumin concentration in cytosols by immunodiffusion. In cytosols of 4 different human target tissues the albumin content varied from 20-30% corresponding to an even higher whole plasma concentration. Steroid binding plasma proteins, such as CBG and SHBG are constituents of this containment. (author)

2018-03-01

Steroid biotransformation, as a powerful tool for generation of steroid active pharmaceutical ingredients and key intermediates, has received widespread attention with increasing market demand for steroid-based drugs. In our study, a bibliometric analysis of steroid biotransformation was performed to trace the research updates and tendencies from 1993 to 2016, based on the Science Citation Index Expanded (SCIE) database. Results showed a notable growth trend in publication outputs. Although the USA was the most productive country between 1993 and 2016, developing nations, including China and India, contributed the prominent growth in recent years (2005–2016). Steroids was the leading journal in this field, and the research outputs had notably increased in the field of ‘Chemistry’, ‘Pharmacology and Pharmacy’ and ‘Biotechnology and Applied Microbiology’. Finally, research focused mainly on the efficient production of novel steroid active pharmaceutical ingredients and key intermediates through steroid biotransformation. Furthermore, cytochrome P450 involved in the side-chain oxidation of sterols has gradually become a hotspot issue in recent years.

The diversion of antiretroviral medications (ARVs) has implications for the integrity and success of HIV care, however little is known about the ARV illicit market. This paper aimed to identify the motivations for buying illicit ARVs and to describe market dynamics. Semi-structured interviews (n = 44) were conducted with substance-involved individuals living with HIV who have a history of purchasing ARVs on the street. Grounded theory was used to code and analyze interviews. Motivations for buying ARVs on the illicit market were: to repurchase ARVs after having diverted them for money or drugs; having limited access or low quality health care; to replace lost or ruined ARVs; and to buy a back-up stock of ARVs. This study identified various structural barriers to HIV treatment and ARV adherence that incentivized ARV diversion. Findings highlight the need to improve patient-provider relationships, ensure continuity of care, and integrate services to engage and retain high-needs populations.

Chronic obstructive pulmonary disease (COPD) is characterized by irreversible airflow limitation and is associated with weight loss and decreased muscle strength and exercise capacity. A double-blinded randomized controlled trial of 32 male COPD patients (age, 54.94 ± 11.27 years) was carried out to assess effects of anabolic steroid in terms of a daily high-protein, high-calorie diet alone or one combined with anabolic steroids on body composition, lung function, and health-related quality of life (HRQL). Outcomes were assessed by anthropometric and spirometric measurements, peak expiratory flow rate, partial pressure of oxygen in arterial blood, 6-minute walk test (6MWT), hand grip test, and HRQL index scores. Measurements were made at baseline and end of treatment (6 weeks). All patients showed significant difference (P < .001) in pulmonary function parameters and anthropometric measurements after 6 weeks of intervention (within-group changes); however, no significant improvement occurred in the pulmonary function parameters between the groups. The difference in exercise capacity (6MWT) and HRQL scores in the treatment group were statistically significant (P < .001) compared with control group after 6 weeks of intervention. In the treatment group, the average 6MWT distance increased from 213.5 m to 268.5 m at 6-week follow-up, and HRQL scores increased from 101.25 to 118.45. Also, HRQL and 6MWT parameters were positively correlated in response to steroid supplementation at the end of the study. Weekly administration of anabolic steroids during 6 weeks increased exercise capacity and quality of life in patients with COPD.

This review synthesizes available epidemiological data on current drug use and substance user treatment admissions in South Africa since 1994, and how changes in the political, economic, and social structures within South Africa, both before and after Apartheid, has made the country more vulnerable to drug use. Based on national surveys, current use of cannabis ranged among adolescents from 2% to 9% and among adults it was 2%, cocaine/crack (0.3%), mandrax/sedatives (0.3%), club drugs/amphetamine-type stimulants (0.2%), opiates (0.1%), and hallucinogens (0.1%). The use of primary illicit substance at admission to South African drug user treatment centers was cannabis 16.9%, methamphetamine (tik) 12.8%, crack/cocaine 9.6%, cannabis and mandrax 3.4%, heroin/opiates 9.2%, and prescription and OTC drugs 2.6%. An increase in substance user treatment admissions has increased. While the prevalence of illicit drug use in South Africa is relatively low compared to the United States and Australia, prevention and intervention policies need to be designed to reduce these levels by targeting the more risky subpopulations identified from this review.

Electrospray ionization tandem mass spectrometry (ESI-MS/MS) was used to investigate the effect of different substitutions introduced during metabolism on fragmentation patterns of four anabolic steroids including methyltestosterone, methandrostenolone, cis-androsterone and adrenosterone, along with their metabolites. Collision-induced dissociation (CID) analysis was performed to correlate the major product ions of 19 steroids with structural features. The analysis is done to portray metabolic alteration, such as incorporation or reduction of double bonds, hydroxylations, and/or oxidation of hydroxyl moieties to keto functional group on steroidal skeleton which leads to drastically changed product ion spectra from the respective classes of steroids, therefore, making them difficult to identify. The comparative ESI-MS/MS study also revealed some characteristic peaks to differentiate different steroidal metabolites and can be useful for the unambiguous identification of anabolic steroids in biological fluid. Moreover, LC-ESI-MS/MS analysis of fermented extract of methyltestosterone, obtained by Macrophomina phaseolina was also investigated. Copyright © 2012 Elsevier Inc. All rights reserved.

Treatment of Anabolic-Androgenic Steroid Dependence: Emerging Evidence and Its Implications

2010-01-01

Currently, few users of anabolic-androgenic steroids (AAS) seek substance-abuse treatment. But this picture may soon change substantially, because illicit AAS use did not become widespread until the 1980s, and consequently the older members of this AAS-using population—those who initiated AAS as youths in the 1980s—are only now reaching middle age. Members of this group, especially those who have developed AAS dependence, may therefore be entering the age of risk for cardiac and psychoneuroendocrine complications sufficient to motivate them for substance-abuse treatment. We suggest that this treatment should address at least three etiologic mechanisms by which AAS dependence might develop. First, individuals with body-image disorders such as “muscle dysmorphia” may become dependent on AAS for their anabolic effects; these body-image disorders may respond to psychological therapies or pharmacologic treatments. Second, AAS suppress the male hypothalamic-pituitary-gonadal axis via their androgenic effects, potentially causing hypogonadism during AAS withdrawal. Men experiencing prolonged dysphoric effects or frank major depression from hypogonadism may desire to resume AAS, thus contributing to AAS dependence. AAS-induced hypogonadism may require treatment with human chorionic gonadotropin or clomiphene to reactivate neuroendocrine function, and may necessitate antidepressant treatments in cases of depression inadequately responsive to endocrine therapies alone. Third, human and animal evidence indicates that AAS also possess hedonic effects, which likely promote dependence via mechanisms shared with classical addictive drugs, especially opioids. Indeed, the opioid antagonist naltrexone blocks AAS dependence in animals. By inference, pharmacological and psychosocial treatments for human opioid dependence might also benefit AAS-dependent individuals. PMID:20188494

Steroid - induced rosacea: A clinical study of 200 patients

Directory of Open Access Journals (Sweden)

Yasmeen J Bhat

2011-01-01

Full Text Available Background: Topical corticosteroids were first introduced for use in 1951. Since then uncontrolled use (abuse has caused many different reactions resembling rosacea - steroid dermatitis or iatrosacea. Multiple pathways including rebound vasodilatation and proinflammatory cytokine release have been proposed as the mechanism for such reactions. Aim: The aim was to study the adverse effects of topical steroid abuse and the response to various treatment modalities. Materials and Methods: Two hundred patients with a history of topical steroid use on face for more than 1 month were studied clinically and various treatments tried. Results: The duration of topical corticosteroid use varied from 1 month to 20 years with an average of 19.76 months. Majority of patients were using potent (class II topical steroids for trivial facial dermatoses. The common adverse effects were erythema, telangiectasia, xerosis, hyperpigmentation, photosensitivity, and rebound phenomenon. No significant change in laboratory investigations was seen. Conclusion: A combination of oral antibiotics and topical tacrolimus is the treatment of choice for steroid-induced rosacea.

Pharmaceutical digital marketing and governance: illicit actors and challenges to global patient safety and public health

Science.gov (United States)

2013-01-01

Background Digital forms of direct-to-consumer pharmaceutical marketing (eDTCA) have globalized in an era of free and open information exchange. Yet, the unregulated expansion of eDTCA has resulted in unaddressed global public health threats. Specifically, illicit online pharmacies are engaged in the sale of purportedly safe, legitimate product that may in fact be counterfeit or substandard. These cybercriminal actors exploit available eDTCA mediums over the Internet to market their suspect products globally. Despite these risks, a detailed assessment of the public health, patient safety, and cybersecurity threats and governance mechanisms to address them has not been conducted. Discussion Illicit online pharmacies represent a significant global public health and patient safety risk. Existing governance mechanisms are insufficient and include lack of adequate adoption in national regulation, ineffective voluntary governance mechanisms, and uneven global law enforcement efforts that have allowed proliferation of these cybercriminals on the web. In order to effectively address this multistakeholder threat, inclusive global governance strategies that engage the information technology, law enforcement and public health sectors should be established. Summary Effective global “eHealth Governance” focused on cybercrime is needed in order to effectively combat illicit online pharmacies. This includes building upon existing Internet governance structures and coordinating partnership between the UN Office of Drugs and Crime that leads the global fight against transnational organized crime and the Internet Governance Forum that is shaping the future of Internet governance. Through a UNODC-IGF governance mechanism, investigation, detection and coordination of activities against illicit online pharmacies and their misuse of eDTCA can commence. PMID:24131576

Guy, Joshua H; Vincent, Grace E

2018-02-06

Exercise-induced heat production is further elevated by exercise performed in hot conditions and this can subsequently impact inflammation, and gastrointestinal (GI) health. Implementing nutrition and supplementation strategies under these conditions may support the hyperthermic response, the systemic inflammatory response, GI permeability and integrity, and exercise performance. Therefore, the aim of this brief review is to explore athletes' inflammatory response of two key biomarkers, lipopolysaccharide (LPS), and interleukin-6 (IL-6), and provide nutrition and supplementation recommendations when exercising in hot conditions. There is emerging evidence that probiotics, glutamine, and vitamin C can preserve GI integrity, which may improve performance during exercise in the heat. Glucose rich food when consumed with water, before and during exercise in the heat, also appear to limit endotoxemia, preserve GI integrity, and reduce the incidence of GI disturbances compared with water alone. The use of non-steroidal anti-inflammatory drugs (NSAIDs) may compromise GI integrity and this may result in greater leakage of endotoxins during long duration exercise in the heat. Further work is required to elucidate the impact of nutrition and supplementation strategies, in particular the use of NSAIDs, when exercising in the heat.

The importance of illicit drug price data and making appropriate adjustments for purity has been repeatedly highlighted for understanding illicit drug markets. The European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) has been collecting retail price data for a number of drug types alongside drug-specific purity information for over 15 years. While these data are useful for a number of monitoring and analytical purposes, they are not without their limitations and there are circumstances where additional adjustment needs to be considered. This paper reviews some conceptual issues and measurement challenges relevant to the interpretation of price data. It also highlights the issues with between-country comparisons of drug prices and introduces the concept of affordability of drugs, going beyond purity-adjustment to account for varying national economies. Based on a 2015 European data set of price and purity data across the heroin and cocaine retail markets, the paper demonstrates a new model for drug market comparative analysis; calculation of drug affordability is achieved by applying to purity-adjusted prices 2015 Price Level Indices (PLI, Eurostat). Available data allowed retail heroin and cocaine market comparison for 27 European countries. The lowest and highest unadjusted prices per gram were observed for heroin: in Estonia, Belgium, Greece and Bulgaria (lowest) and Finland, Ireland, Sweden and Latvia (highest); for cocaine: the Netherlands, Belgium and the United Kingdom (lowest) and Turkey, Finland, Estonia and Romania (highest). The affordability per gram of heroin and cocaine when taking into account adjustment for both purity and economy demonstrates different patterns. It is argued that purity-adjusted price alone provides an incomplete comparison of retail price across countries. The proposed new method takes account of the differing economic conditions within European countries, thus providing a more sophisticated tool for cross

Anabolic steroid use among students at a British college of technology.

Williamson, D J

1993-01-01

To determine the rate of current or previous use of anabolic steroids by students at a UK college of technology, a questionnaire survey of 687 day students was conducted. The questionnaire began with a general section for all of the students, which ended with the question 'Have you ever used anabolic steroids?'. A further section specifically for anabolic steroid users examined patterns of use, and how certain circumstances might affect the individual's decision to use anabolic steroids. The ...

Preoperative High-Dose Steroid Has Long-Term Beneficial Effects for Myasthenia Gravis

Full Text Available Previous studies addressing preoperative steroid treatment have revealed that control of myasthenia gravis (MG with steroids prior to surgery appeared to stabilize postoperative status. The purpose of our study was to clarify the clinical benefits of the preoperative programmed high-dose steroid treatment on the long-term outcomes of MG patients. We retrospectively reviewed the records of 171 MG patients who were followed up after undergoing thymectomy in our hospital between 1988 and 2006. One hundred and thirteen patients in the programmed treatment group had received preoperative steroid treatment, while 58 patients received no steroid treatment during the preoperative period. Clinical remission, which was defined as the achievement of the modified pharmacologic remission (PR for at least 1 year, and clinical benefits were compared between the two groups. With regard to the remission after thymectomy, Kaplan-Meier life-table curves for patients in the preoperative steroid treatment group versus those for patients in the no steroid preoperative treatment group revealed a significantly higher probability of the PR in the preoperative steroid treatment group (log-rank test, P<0.01. This study might be the first, as per our knowledge, to indicate that preoperative programmed high-dose steroid treatment has long-term beneficial effects for MG patients.

A series of forensic toxicology and drug seizure cases involving illicit fentanyl alone and in combination with heroin, cocaine or heroin and cocaine.

Marinetti, Laureen J; Ehlers, Brooke J

2014-10-01

The Montgomery County Coroner's Office Toxicology Section and the Miami Valley Regional Crime Lab (MVRCL) Drug Chemistry Section have been receiving case work in drug seizures, death cases and human performance cases involving products marketed as heroin or as illicit fentanyl. Upon analysis by the Drug Chemistry Section, these products were found to contain various drug(s) including illicit fentanyl only, illicit fentanyl and heroin, illicit fentanyl and cocaine and illicit fentanyl, heroin and cocaine. Both the Chemistry and Toxicology Sections began seeing these combinations starting in late October 2013. The percentage of the combinations encountered by the MVRCL as well as the physical appearance of the product, and the results of presumptive screening tests will be discussed. The demographics of the users and the results of toxicology and autopsy findings on the decedents will also be discussed. According to regional drug task force undercover agents, there is evidence that some of the products are being sold as illicit fentanyl and not just as a heroin product. Also, there is no evidence to support that the fentanyl source is being diverted from pharmaceutical grade fentanyl. The chemistry section currently has over 109 confirmed cases, and the toxicology section currently has 81 confirmed drug deaths, 8 driving under the influence of drugs and 1 suicidal hanging. Both sections are continuing to see these cases at the present time. © The Author 2014. Published by Oxford University Press. All rights reserved.

Combating illicit trafficking of nuclear material and other radioactive sources in Republic of Bulgaria

International Nuclear Information System (INIS)

Gotsev, A.; Dimitov, K.

2001-01-01

The turbulent history of the Republic of Bulgaria is proof of its importance for the commercial and military interests of the nations that have conquered and exploited the country through the ages. It is clear that it is the connecting node of two continents, Europe and Asia. It is a natural stop in the movement of goods for transcontinental commercial purposes as well as a natural resting place for the movement of armies during the ancient and medieval times. The geopolitical situation that currently exists in the Republic of Bulgaria may form conditions for illicit trafficking. This paper gives a short description of the efforts of the Government of Bulgaria to combat the illicit trafficking of nuclear material and other radioactive sources. (author)

Cardiotoxic effects of cocaine and anabolic-androgenic steroids in the athlete.

Science.gov (United States)

Welder, A A; Melchert, R B

1993-04-01

Cocaine and anabolic-androgenic steroid abuse have become major drug problems in the United States. Cocaine has been designated as "the drug of greatest national health concern" while as many as 1 million Americans have used or are currently using anabolic-androgenic steroids to promote athletic performance and/or improve physical appearance. Unfavorable cardiovascular events have been linked to both cocaine and anabolic-androgenic steroid abuse in healthy, physically active individuals. Deaths of several United States athletes in 1986 focused attention on the life-threatening cardiovascular consequences of cocaine abuse. Reports of myocardial injury with anabolic-androgenic steroid abuse are anecdotal. Nevertheless, case reports have illustrated the alarming cardiotoxic potential of these steroids in athletes. Anabolic-androgenic steroids were correlated to myocardial infarction in weight lifters and cardiomyopathy in a former professional football player. From the total emergency room episodes where cocaine was mentioned in 1990, approximately 66% of these episodes occurred in young individuals 18-29 years of age. Over 500,000 of the individuals currently taking anabolic-androgenic steroids for nonmedical purposes are high-school children. Because cocaine and anabolic-androgenic steroids are used improperly, more focus needs to be paid to the toxic mechanisms of their adverse effects. Therefore, the purpose of this review is to discuss mechanisms whereby exercise and/or exercise training may alter the cardiovascular responses to these drugs. Furthermore, we would like to illustrate that contrary to the popular belief, acute and chronic abuse of cocaine and anabolic-androgenic steroids have a negative impact on exercise performance.

This study aimed to understand the usage patterns and correlates of illicit drug use among schoolchildren in Colombo district, Sri Lanka. A cross-sectional study was carried out among grade 10 and 12 students using a self-administered questionnaire. From the 6000 students selected, 5353(89.22%) responded. Betel chewing with tobacco was seen in 28.48% males and 10.44% females. Substances such as Barbul, Madana Modaka, and cough syrups that are not established as illicit drugs were used as psychoactive substances. Ingredients of some of these compounds are not fully understood or regulated. Prevalence of cannabis use was 3.85% in males and 0.24% in females. Studying nonscience subjects for Advanced Level, doing sports, low academic performance, and peer smoking significantly increased the odds of using one or more substances (P substances were used by schoolchildren. More strategies to prevent further aggravation of these behaviors are needed. Constituents of some compounds are not understood and need further evaluation. Recognized high-risk groups can be targets for preventive and cessation programs.

To determine if a particulate steroid which has a risk for embolic infarct would be more effective than a non-particulate steroid for transforaminal epidural steroid injection (TFESI). The purpose of this study was (1) to compare the effect of cervical TFESI using particulate (e.g., triamcinolone) and non-particulate (e.g., dexamethasone) steroids and (2) to evaluate the effectiveness of cervical TFESI in general. From January 2006 to August 2008, 159 consecutive patients [male:female (M:F) 89:70; mean age 53 years, range 33-75 years] who underwent cervical TFESI were included in this non-randomized study. For cervical TFESI, triamcinolone was injected into 97 patients and dexamethasone into 62 patients. Short-term follow-up was conducted within 1 month. The outcome was classified as effective or ineffective. Fisher's exact test was used to analyze the difference of outcome according to the injected steroid (triamcinolone vs dexamethasone). Other possible outcome predictors, such as age, gender, duration of radiculopathy, predominant symptom, attack of radiculopathy, cause of radiculopathy, number of nerve root compression levels, previous operation, and failure of previous interlaminar epidural injection, were also analyzed. Cervical TFESI using triamcinolone (78/97, 80.4%) was slightly more effective than that using dexamethasone (43/62, 69.4%), which was not significant (P = 0.129). In general, cervical TFESIs were effective in 121 of 159 patients (76.1%) at short-term follow-up. The only significant outcome predictor was whether the patient had had a previous operation (6/13, 46/2%) or not (115/146, 78.8%) (P = 0.015). There was no significant difference between particulate or non-particulate steroid for the effect of cervical TFESI. Cervical TFESI was effective in managing cervical radiculopathy in general.

2016-01-01

Full Text Available Background. The aim of the study was to explore the prevalence of illicit drug use in a group of Polish adolescents with type 1 diabetes (DM1 in comparison with a national cohort of their healthy peers. Methods. Two hundred and nine adolescents with DM1, aged 15–18 years, were studied in 2013 with an anonymous questionnaire prepared for the European School Survey Project on Alcohol and Other Drugs (ESPAD. The control group was a representative sample of 12114 students at the same age who took part in ESPAD in 2011. Metabolic control was regarded as good if self-reported HbA1c was <8% or poor if HbA1c was ≥8%. Results. Lifetime prevalence of illicit drug use was lower among adolescents with DM1 than in the control group [58 (28% versus 5524 (46%, p=10-5]. Cannabis preparations were the most frequently used substances [38 (18.3% versus 3976 (33.1%, p=10-5], followed by tranquilizers, sedatives, and amphetamine. Lifetime and last 12-month use of cannabis were associated with poorer glycemic control (HbA1c ≥ 8%, p<0.01 and 0.02, respectively. Conclusions. Adolescents with DM1 report using illicit drugs to a lesser extent than their healthy peers. The use of cannabis is associated with a poorer metabolic control in teens with DM1.

A rapid, selective and sensitive UPLC-MS/MS assay was established to determine the plasma concentrations of four steroidal saponins. Sprague-Dawley rats were allocated to four groups which were orally administered Anemarrhena asphodeloides extracts (ASE), ASE combined with macromolecular fraction (ASE-MF), ASE combined with small molecule fraction (ASE-SF) and ASE combined with small molecule and macromolecular fraction (ASE-SF-MF) containing approximately the same dose of ASE. At different time points, the concentration of timosaponin BII, anemarsaponin BIII, timosaponin AIII and timosaponin E1 in rat plasma were determined and main pharmacokinetic parameters including Cmax, Tmax, T1/2, AUC were calculated using the DAS 3.2 software package. The statistical analysis was performed using the Student's t-test with p saponins. It was found that Cmax and AUC of four steroidal saponins in group ASE-SF and ASE-SF-MF, were significantly increased compared with those in group ASE. These results indicate that SF in A. asphodeloides extracts could increase the absorption and improve the bioavailability of the steroidal saponins.

This longitudinal study examined the association between psychosocial antecedents, including illicit drug use, and adult compulsive buying (CB) across a 29-year time period from mean age 14 to mean age 43. Participants originally came from a community-based random sample of residents in two upstate New York counties. Multivariate linear regression analysis was used to study the relationship between the participant’s earlier psychosocial antecedents and adult CB in the fifth decade of life. The results of the multivariate linear regression analyses showed that gender (female), earlier adult impulse buying (IB), depressive mood, illicit drug use, and concurrent ADHD symptoms were all significantly associated with adult CB at mean age 43. It is important that clinicians treating CB in adults should consider the role of drug use, symptoms of ADHD, IB, depression, and family factors in CB. PMID:26165963

The German system to prevent, detect and respond to illicit uses of nuclear materials and radioactive sources

International Nuclear Information System (INIS)

Fechner, J.B.

2001-01-01

The German system to prevent, detect and respond to illicit uses of nuclear materials and radioactive sources consists of a variety of different elements: International and national laws and regulations covering safeguards, physical protection, and import/export control; Licensing and regulatory supervision of all activities related to nuclear materials and radioactive sources, including import and export; Responsibility of the licensee to ensure compliance with licensing conditions; sanctions; Law enforcement by police, security and customs authorities; prosecution and penalties; Detection of illicitly trafficked radioactive materials through intelligence and technical means; analysis capabilities; Response arrangements for normal and for severe cases of illicit use of nuclear materials; Participation in international programmes and POC-systems. Safeguards measures have been implemented in Germany in accordance with the Non- Proliferation Treaty and with safeguards agreements based on INFCIRC/153. As Germany is a member of the European Union, the Euratom Treaty and the Euratom-Ordinance Nr. 3227/76 together with the Verification Agreement between the IAEA, the European Commission and the European Member States have led to safeguards measures jointly implemented by the IAEA and by Euratom. The relevant international law for the physical protection of nuclear material in force in Germany is the Convention on the Physical Protection of Nuclear Material. The recommendations on physical protection objectives and fundamentals and on physical protection measures specified in INFCIRC/225/Rev. 4 have been taken into account in various national regulations pertaining to the national design basis threat, the physical protection of LWR nuclear power plants, of interim spent fuel storage facilities, of facilities containing category III material, of nuclear material and radioactive waste transports by road or railway vehicles, aircraft or sea vessels; additional guidelines

The Central Effects of Androgenic-anabolic Steroid Use.

Science.gov (United States)

Mędraś, Marek; Brona, Anna; Jóźków, Paweł

: Millions of men use androgenic-anabolic steroids (AAS) to stimulate muscle growth and improve physical appearance. Although 1 out of 3 people who uses androgenic-anabolic steroids develops a steroid use disorder, the effects of the drugs on the central nervous system and the psyche are still not well understood. Although most addictive substances improve mood immediately after administration, AAS exert less pronounced euphoric effects. Instead, they are primarily taken for the delayed gratification of increased muscle mass. Withdrawal from AAS may lead to a range of somatic and psychiatric symptoms, and, in many cases, comprehensive treatment supervised by an endocrinologist and a psychiatrist is required.

The U.S. Environmental Protection Agency (EPA) has developed methods for the analysis of steroid hormones in water, soil, sediment, and municipal biosolids by HRGC/HRMS (EPA Method 1698). Following the guidelines provided in US-EPA Method 1698, the extraction methods were validated with reagent water and applied to municipal wastewater, surface water, and municipal biosolids using GC/MS/MS for the analysis of nine most commonly detected steroid hormones. This is the first reported comparison of the separatory funnel extraction (SFE), continuous liquid-liquid extraction (CLLE), and Soxhlet extraction methods developed by the U.S. EPA. Furthermore, a solid phase extraction (SPE) method was also developed in-house for the extraction of steroid hormones from aquatic environmental samples. This study provides valuable information regarding the robustness of the different extraction methods. Statistical analysis of the data showed that SPE-based methods provided better recovery efficiencies and lower variability of the steroid hormones followed by SFE. The analytical methods developed in-house for extraction of biosolids showed a wide recovery range; however, the variability was low (≤ 7% RSD). Soxhlet extraction and CLLE are lengthy procedures and have been shown to provide highly variably recovery efficiencies. The results of this study are guidance for better sample preparation strategies in analytical methods for steroid hormone analysis, and SPE adds to the choice in environmental sample analysis.

Recognizing the actuality and importance of nuclear material illicit trafficking problems, the Security Service of Ukraine pays great attention to the security and theft prevention of nuclear materials in Ukraine. For this purpose the state system, which includes organizational and legislative measures, has been established and is functioning. Within the frame of this system the detection and perception of illicit trafficking of nuclear materials and radioactive substances take an important place in the work of law enforcement authorities, including Security Service, in Ukraine. The Laws of Ukraine nuclear power utilization and radioactive safety, sanitary and epidemiological population control, the respective articles of the Criminal Code of Ukraine (art. 228-2, 228-3, 228-4, 228-5) and the statement of the Cabinet of Ministers of Ukraine no. 207 on 04.03.1997 which determines the interaction procedure between executive authorities in case of illicit trafficking of radiation source detection, are its legislative basis. The analysis of the situation shows that this problem became the most pressing after the USSR collapse in 1991 due to some objective and subjective causes. Some criminals and common staff of the enterprises and organizations which were responsible for the above mentioned materials as well as former military men were involved in illegal activity associated with illicit trafficking of nuclear materials and radioactive substances. Although after the USSR collapsed the Ukraine had the nuclear arsenal which was the third in the world, it did not become the source of nuclear weapons material proliferation. It shows the effectiveness of the measures undertaken by the government within the system of nuclear material physical protection provision. It is evident that nuclear weapon removal from the territory of Ukraine was performed without any case of its loss or theft. Therefore, currently in Ukraine there is only the necessary amount of nuclear material

Gamma-emitting steroid tracers for use in the radioimmunoassay of steroids have a number of advantages over the more common tritiated tracers. The steroid derivatives aldosterone-3-(p-hydroxybenzoyl) hydrazone, aldosterone-3-(p-hydroxyphenylpropionyl)hydrazone, deoxycorticosterone-3-(p-hydroxyphenylpropionyl)hydrazone, and cortisol-3-(p-hydroxyphenylpropionyl)hydrazone were synthesized by a one-step procedure and iodinated ([ 125 I]). To illustrate the usefulness of these derivatives, we describe the details of a cortisol radioimmunoassay. The use of the radioiodinated tracer appeared to increase the specificity of the antigen-antibody reaction when compared with [ 3 H]cortisol. The methodology involved in the preparation of the steroid derivatives described above can be extended to other 3-oxo-4-ene-containing steroids, with the advantages of economy, simplicity, and versatility

The effect of treatment with an anabolic steroid (nandrolone decanoate) on the muscle mass of plantaris and soleus of a rats in hindlimb suspension, and on the isomyosin expression in these muscles, was investigated in young female rats divided into four groups: normal control (NC), normal steroid (NS), normal suspension (N-sus), and suspension steroid (sus-S). Steroid treatment of suspended animals (sus-S vs N-sus) was found to partially spare body weight and muscle weight, as well as myofibril content of plantaris (but not soleus), but did not modify the isomyosin pattern induced by suspension. In normal rats (NS vs NC), steroid treatment did enhance body weight and plantaris muscle weight; the treatment did not alter isomyosin expression in either muscle type.

Although rates of illicit drug use are considerably lower in Mexico than in the United States, rates in Mexico have risen significantly. This increase has particular implications for Mexican women and US migrants, who are considered at increased risk of drug use. Due to drug reforms enacted in Mexico in 2008, it is critical to evaluate patterns of drug use among migrants who reside in both regions. We analysed a sample of Mexicans (N=16,249) surveyed during a national household survey in 2011, the Encuesta Nacional de Adicciones (National Survey of Addictions). Comparative analyses based on Mexicans' migrant status - (1) never in the United States, (2) visited the United States, or (3) lived in the United States (transnationals) - featured analysis of variance and Chi-square global tests. Two multilevel regressions were conducted to determine the relationships among migrant status, women, and illicit drug use. Comparative findings showed significant differences in type and number of drugs used among Mexicans by migrant status. The regression models showed that compared with Mexicans who had never visited the United States, Mexican transnationals were more likely to report having used drugs (OR=2.453, 95% CI=1.933, 3.113) and using more illicit drugs (IRR=2.061, 95% CI=1.626, 2.613). Women were less likely than men to report having used drugs (OR=0.187, 95% CI=0.146, 0.239) and using more illicit drugs (IRR=0.153, 95% CI=0.116, 0.202). Overall, the findings support further exploration of risk factors for illicit drug use among Mexican transnationals, who exhibit greater drug use behaviours than Mexicans never in the United States. Because drug reform mandates referrals to treatment for those with recurrent issues of drug use, it is critical for the Mexican government and civic society to develop the capacity to offer evidence-based substance abuse treatment for returning migrants with high-risk drug behaviours.
