Evaluation of nicotine and cotinine in human hair.   总被引:4,自引:0,他引:4  
To validate data on tobacco use, the authors investigated the use of hair samples for quantifying nicotine and cotinine by gas chromatography/mass spectrometry. Hair was taken from 22 nonsmokers and 42 smokers, cut close to the scalp at the back of the head. The hair (about 100 mg from each subject) was incubated in 3 mL of 1N NaOH at 100 degrees C for 1 h. After this, the samples were extracted by diethyl ether. The drugs were separated on a 12-m BP-5 capillary column and detected using selected ion monitoring (nicotine, m/z 84; cotinine, m/z 98). Hair from nonsmokers and smokers contains nicotine and cotinine. Although it is difficult to determine an absolute cutoff level, an amount greater than 2 ng of nicotine per milligram of hair can be used to differentiate smokers from nonsmokers. In the population of nonsmokers, the influence of environmental smoke exposure was noted.  相似文献

This article is about the socio‐legal construction of one of the least‐loved birds in the United Kingdom: the ‘seagull'. In particular, it is about how the gull has been brought within the realm of the ‘anti‐social', in a context in which urban‐nesting gulls (of which there are many in the United Kingdom) are cast as causing a great deal of public nuisance, ranging from noise, aggression, and mess, to attacks, injuries, and stress. The article examines the measures adopted by local authorities to regulate the gull population – and to regulate people, in the name of regulating gulls – and shows how a construction of the ‘seagull’ underpins and justifies this regulatory framework. It argues that the story of the regulation of seagulls in the United Kingdom is also a story about the construction of public space, to the point that the measures adopted here challenge the very idea of public space.  相似文献

The purpose of this article is to determine how the heterogeneity of the different regulatory frameworks governing genetic laboratories in Australia, France, the United Kingdom, and the United States hinder the international availability of genetic tests. We conclude that a better understanding of the various national standards governing genetic laboratories may help health professionals choose laboratories for referral in an evidence based manner in order to protect the patient's best interests.  相似文献

In 2007, the European Union adopted a lex specialis, Regulation (EC) No. 1394/2007 on advanced therapy medicinal products (ATMPs), a new legal category of medical product in regenerative medicine. The regulation applies to ATMPs prepared industrially or manufactured by a method involving an industrial process. It also provides a hospital exemption, which means that medicinal products not regulated by EU law do not benefit from a harmonized regime across the European Union but have to respect national laws. This article describes the recent EU laws, and contrasts two national regimes, asking how France and the United Kingdom regulate ATMPs which do and do not fall under the scope of Regulation (EC) No. 1394/2007. What are the different legal categories and their enforceable regimes, and how does the evolution of these highly complex regimes interact with the material world of regenerative medicine and the regulatory bodies and socioeconomic actors participating in it?  相似文献

The development of clinical ethics committees in the United Kingdom raises a number of important questions about the extent to which they are compatible with the normative values of due process. If committees are to be active in delivering ethics services, it is argued that attention to due process is important. Based on research outcomes, it seems that the chairs of the United Kingdom clinical ethics committees who responded are reasonably satisfied about the ability of their committees to make ethical decisions and slightly less confident about their ability to make legal decisions. If these committees are to make potentially far-reaching decisions (whether or not involving live consultations), it is argued here that they must pay attention to the rules associated with the legal concept of due process. Equally, evaluation of the clinical ethics committee's counterpart in the United States suggests that they may become increasingly authoritative, especially as their role becomes entrenched. This makes attention to due process even more important. However, it is also proposed that, when committees become concerned about due process, their ability to "do ethics" is constrained.  相似文献

Tobacco consumption is a global epidemic responsible for a vast burden of disease. With pharmacological properties sought-after by consumers and responsible for addiction issues, nicotine is the main reason of this phenomenon. Accordingly, smokeless tobacco products are of growing popularity in sport owing to potential performance enhancing properties and absence of adverse effects on the respiratory system. Nevertheless, nicotine does not appear on the 2011 World Anti-Doping Agency (WADA) Prohibited List or Monitoring Program by lack of a comprehensive large-scale prevalence survey. Thus, this work describes a one-year monitoring study on urine specimens from professional athletes of different disciplines covering 2010 and 2011. A method for the detection and quantification of nicotine, its major metabolites (cotinine, trans-3-hydroxycotinine, nicotine-N'-oxide and cotinine-N-oxide) and minor tobacco alkaloids (anabasine, anatabine and nornicotine) was developed, relying on ultra-high pressure liquid chromatography coupled to triple quadrupole mass spectrometry (UHPLC-TQ-MS/MS). A simple and fast dilute-and-shoot sample treatment was performed, followed by hydrophilic interaction chromatography-tandem mass spectrometry (HILIC-MS/MS) operated in positive electrospray ionization (ESI) mode with multiple reaction monitoring (MRM) data acquisition. After method validation, assessing the prevalence of nicotine consumption in sport involved analysis of 2185 urine samples, accounting for 43 different sports. Concentrations distribution of major nicotine metabolites, minor nicotine metabolites and tobacco alkaloids ranged from 10 (LLOQ) to 32,223, 6670 and 538 ng/mL, respectively. Compounds of interest were detected in trace levels in 23.0% of urine specimens, with concentration levels corresponding to an exposure within the last three days for 18.3% of samples. Likewise, hypothesizing conservative concentration limits for active nicotine consumption prior and/or during sport practice (50 ng/mL for nicotine, cotinine and trans-3-hydroxycotinine and 25 ng/mL for nicotine-N'-oxide, cotinine-N-oxide, anabasine, anatabine and nornicotine) revealed a prevalence of 15.3% amongst athletes. While this number may appear lower than the worldwide smoking prevalence of around 25%, focusing the study on selected sports highlighted more alarming findings. Indeed, active nicotine consumption in ice hockey, skiing, biathlon, bobsleigh, skating, football, basketball, volleyball, rugby, American football, wrestling and gymnastics was found to range between 19.0 and 55.6%. Therefore, considering the adverse effects of smoking on the respiratory tract and numerous health threats detrimental to sport practice at top level, likelihood of smokeless tobacco consumption for performance enhancement is greatly supported.  相似文献

The practice of allocating scarce organs in medicine is an ethical minefield. Due to the organ shortage, organ procurement agencies in both the United Kingdom and the United States are placed in the unenviable position of having to choose a limited number of patients to compete equally for life-saving treatment. They do this by composing multidisciplinary transplant teams, which must evaluate transplant candidates and their complex range of personal, medical, environmental, psychiatric and financial characteristics. During the candidate assessment process, such teams may often be torn between their moral duty to save those who are most in need, considerations of efficiency, and the battle against forming moral judgments about particular candidates. Several ethical approaches can be adopted by transplant teams during the decision-making process, but do these ideologies provide adequate justification for their sometimes controversial decisions? This article provides a detailed examination of the ethical principles available to transplant teams in the United Kingdom and the United States, and the effect that these principles have on assessment procedures, organ allocation protocols, transplant candidates and their prospects.  相似文献

A fatal case of multidrug poisoning by tramadol and nicotine is reported. Tramadol is a centrally acting analgesic used in the treatment of moderate to severe acute or chronic pain. Nicotine, a lipid-soluble alkaloid, is one of the most readily available drugs in modern society. A 46-year-old man was found dead in his bed, and a suicide note was discovered near the body. He had 25 transdermal nicotine patches attached to his thorax and abdomen. Two half emptied bottles were found on the bedside table; the toxicological examination revealed that they contained tobacco and nicotine as well as other drugs such as diphenhydramine. At autopsy, areas of fresh and old myocardial infarction as well as diffuse pulmonary congestion and edema were present. The tramadol concentration was 6.6 μg/mL in femoral venous blood, while levels of nicotine and its primary metabolite cotinine were determined to be 0.6 and 2.0 μg/mL in femoral venous blood. Based on these results, we determined the cause of death to be cardiorespiratory failure induced by the additive effects of tramadol and nicotine shortly after consumption.  相似文献

The introduction of the national minimum wage in the United Kingdom poses a new challenge for labour law because of its novel enforcement methods. This article examines carefully the possibilities for enforcing the new statutory minimum wage in the light of regulatory theory and the government's desire to make the wage 'self-enforcing'. It offers policy suggestions as to how the different enforcement strands can be best made to work together and highlights some of the dangers the government needs to be aware of in this area.  相似文献

Blacks have worse overall health than whites in both the United States and the United Kingdom. However, the relative difference in health between the two groups within each cultural context differs between each context. In this article, we attempt to glean insights into these health disparities. We do so by first examining what is currently known about differences in morbidity and mortality for blacks and whites in the United States and the United Kingdom. We then turn to medical examination data by race and country of birth in an attempt to further untangle the complex interplay of socioeconomic status (SES), race, and racism as determinants of health in the United States and the United Kingdom. We find that (1) longer exposure of blacks to the recipient country is a risk for mortality in the United States but not in the United Kingdom; (2) adjustment for SES matters a good deal for mortality in the United States, but less so in the United Kingdom; (3) morbidity indicators do not paint a clear picture of black disadvantage relative to whites in either context; and (4) were one to consider medical examination data alone, differences between the two groups exist only in the United States. Taken together, we conclude that it is possible that the "less racist" United Kingdom provides a healthier environment for blacks than the United States. However, there remain many mysteries that escape simple explanation. Our findings raise more questions than they answer, and the health risks and health status of blacks in the United States are much more complex than previously thought.  相似文献

Xenotransplantation - the transfer of living tissue between species - has long been heralded as a potential solution to the severe organ shortage crisis experienced by the United Kingdom and other 'developed' nations. However, the significant risks which accompany this biotechnology led the United Kingdom to adopt a cautious approach to its regulation, with the establishment of a non-departmental public body - UKXIRA - to oversee the development of this technology on a national basis. In December 2006 UKXIRA was quietly disbanded and replaced with revised guidance, which entrusts the regulation of xenotransplantation largely to research ethics committees. In this article we seek to problematize this new regulatory framework, arguing that specialist expertise and national oversight are necessary components of an adequate regulatory framework for a biotechnology which poses new orders of risk, challenges the adequacy of traditional understandings of autonomy and consent, and raises significant animal welfare concerns. We argue for a more considered and holistic approach, based on adequate consultation, to regulating biotechnological developments in the United Kingdom.  相似文献

The regulatory approach to privacy protection taken by many foreign jurisdictions is markedly different from that of the United States. The European Union (EU) best illustrates the international approach with its comprehensive privacy directive that applies to all EU members. By contrast, the approach regarding data privacy in the United States has been to pass industry-specific laws and often only in response to public outcry over some privacy concern. These fundamental differences have been the source of some conflict in international commercial transacting. Now that the global community is committed to eliminating terrorism, it remains to be seen if these different attitudes toward privacy by the United States and much of the rest of the world will affect global attempts to weed out terrorists. This article discusses the constitutional basis for most US policy approaches to privacy regulation. The article explains how the US constitution is the source for most of the differences between the US and international regulatory approaches to information privacy. Finally, the discussion addresses how new issues regarding privacy in the war on terrorism may be addressed by US Constitutional law.  相似文献

A 35-year-old male was found lying in a prone position in his room. He was in cardiopulmonary arrest on arrival to hospital and was pronounced dead. There was no attempt at resuscitation. No miosis was observed on admission. At post-mortem his stomach contained 170 g greenish liquid with a small amount of shredded tobacco leaves. The serum cholinesterase activities were 47-90 IU (normal range for male: 200-440 IU). GC and GC-MS analyses showed nicotine (21.8 mg), methomyl (304 mg), and triazolam (1.69 mg) in his stomach. He had consumed tobacco leaves, Lannate containing water soluble methomyl (45%), and Halcion tablets containing 0.25 mg triazolam. Methomyl concentrations in blood were 3-8 ng/ml. Substantial amounts of methomyl (2260-2680 ng/ml) were detected in cerebrospinal fluid and vitreous humor. Nicotine concentrations in blood ranged from 222 to 733 ng/ml. A small amount of triazolam was detected only in bile (176 ng/ml) and liver (23 ng/g). The cause of death was respiratory paralysis produced by the additive effects of methomyl and nicotine shortly after consumption.  相似文献

This article highlights the spectacular growth of benefit sanctions in the United Kingdom which, at their peak, exceeded the number of fines imposed in the criminal courts. It proposes a three‐fold typology of monetary sanctions – punitive judicial sanctions, exemplified by court fines, regulatory administrative sanctions, exemplified by parking penalties, and disciplinary administrative monetary sanctions, exemplified by benefit sanctions – and compares them in terms of their main aims, how they are imposed, whether the interests of those sanctioned are protected, their severity, the socio‐economic characteristics of offenders, the hardship caused, how proportionate they are, and whether they are compatible with justice. It argues that they are particularly problematic because their severity causes great and disproportionate hardship, and because, in addition to punishing offenders, they also attempt to discipline them by managing their behaviour, and concludes that, in the United Kingdom, they function as a key instrument for disciplining and managing the poor.  相似文献

The regulatory state and the welfare state are two institutions that are central to the analysis of the characteristics of capitalist democracies. The regulatory state is seen as focused on market failures and trust‐busting, while the welfare state is said to shield citizens from the negative redistributive effects and externalities of the market. This article explores the relations and boundaries between the welfare state and the regulatory state in the electricity sectors in the United Kingdom, Sweden, and Israel. It demonstrates the emergence of social policy within the context of liberalized, privatized, and (de)regulated electricity sectors. This article finds that the boundaries between the regulatory state and the welfare state are blurred in Israel and the United Kingdom but not in Sweden. These findings may imply a connection between the welfare state and the regulatory state, suggesting that a strong welfare state is needed in order to maintain regulation‐for‐competition.  相似文献

This notice establishes a uniform protocol for the analysis of nicotine, total moisture, and pH in smokeless tobacco products. This protocol was designed to implement the requirement of the Comprehensive Smokeless Tobacco Health Education Act (CSTHEA) of 1986 (15 U.S.C. 4401 et seq., Pub. L. 99-252), which requires that each entity manufacturing, packaging, or importing smokeless tobacco products shall annually provide the Secretary of Health and Human Services (HHS) with a specification of the quantity of nicotine contained in each smokeless tobacco product.  相似文献

In 1993 Jon Venables and Robert Thompson were found guilty of the abduction and murder of two-year-old James Bulger. Aged ten at the time of the offence, the children were tried in an adult court before a judge and jury amidst a blaze of publicity. They were named by the trial judge and sentenced to detention at Her Majesty's Pleasure [HMp]. The Home Secretary set a minimum tariff of fifteen years imprisonment. In December 1999 the European Court of Human Rights held that, in the conduct of the trial and the fixing of the tariff, the United Kingdom government was responsible for violating the European Convention on Human Rights. This article maps how the case became a watershed in youth justice procedure and practice influencing Labour's proposals for reform and the 1998 Crime and Disorder Act. Examining the progression of appeals through the domestic and European courts, it explores the dichotomous philosophies separating the United Kingdom and European approaches to the age of criminal responsibility, the prosecution and punishment of children, and the influence of political policy on judicial decisions. Finally, the 'backlash' against 'threatening children', the affirmation of adult power and knowledge, and the implications of the European judgments in the context of a rights-based agenda are analysed.  相似文献

Homoeopathy has a significant clinical history, tracing its roots back to Hippocrates and more latterly to Dr Christian (Samuel) Hahnemann (1755-1843), a Saxon physician. In the last 30 years it has ridden a wave of resurgent interest and practice associated with disillusionment with orthodox medicine and the emergence of complementary therapies. However, recent years have seen a series of meta-analyses that have suggested that the therapeutic claims of homeopathy lack scientific justification. A 2010 report of the Science and Technology Committee of the United Kingdom House of Commons recommended that it cease to be a beneficiary of NHS funding because of its lack of scientific credibility. In Australia the National Health and Medical Research Council is expected to publish a statement on the ethics of health practitioners' use of homoeopathy in 2013. In India, England, New South Wales and Western Australia civil, criminal and coronial decisions have reached deeply troubling conclusions about homoeopaths and the risk that they pose for counter-therapeutic outcomes, including the causing of deaths. The legal decisions, in conjunction with the recent analyses of homoeopathy's claims, are such as to raise confronting health care and legal issues relating to matters as diverse as consumer protection and criminal liability. They suggest that the profession is not suitable for formal registration and regulation lest such a status lend to it a legitimacy that it does not warrant.  相似文献

This article considers business understandings of two of the principal features of the new regulatory governance. First, it focus on attempts to place greater responsibility for risk regulation on business and asks how well equipped they are to manage this. Second, it examines the decentering of the state and considers how business organizations view the influence of nonstate actors on their business regulation. These issues are discussed with reference to data from two different research projects in the United Kingdom. The findings question the implicit assumptions the new regulatory governance makes about how well equipped businesses are to manage the risks they generate and how able nonstate influences are to influence the full range of businesses.  相似文献
