Analysis of androgen and anti-androgen regulation of KLK-related peptidase 2, 3, and 4 alternative transcripts in prostate cancer

We assessed whether alternative transcripts (using KLK2, KLK3 and KLK4 as models) are differentially regulated by androgens and anti-androgens as an indicator of prostate cancers as they acquire treatment resistance. Using RNAseq of LNCaP cells treated with dihydrotestosterone, bicalutamide and enzalutamide, we show that the expression of variant KLK transcripts is markedly different to other variant transcripts at those loci. We also reveal that KLK variants are also over 2-fold more highly expressed in prostate cancers compared to their corresponding normal prostate. We propose that androgens and anti-androgens can activate specific variant transcripts of critical prostate cancer genes during treatment resistance

Representation and misrepresentation of scientific evidence in contemporary tobacco regulation:a review of tobacco industry submissions to the UK Government consultation on standardised packaging

BACKGROUND: Standardised packaging (SP) of tobacco products is an innovative tobacco control measure opposed by transnational tobacco companies (TTCs) whose responses to the UK government's public consultation on SP argued that evidence was inadequate to support implementing the measure. The government's initial decision, announced 11 months after the consultation closed, was to wait for 'more evidence', but four months later a second 'independent review' was launched. In view of the centrality of evidence to debates over SP and TTCs' history of denying harms and manufacturing uncertainty about scientific evidence, we analysed their submissions to examine how they used evidence to oppose SP. METHODS AND FINDINGS: We purposively selected and analysed two TTC submissions using a verification-oriented cross-documentary method to ascertain how published studies were used and interpretive analysis with a constructivist grounded theory approach to examine the conceptual significance of TTC critiques. The companies' overall argument was that the SP evidence base was seriously flawed and did not warrant the introduction of SP. However, this argument was underpinned by three complementary techniques that misrepresented the evidence base. First, published studies were repeatedly misquoted, distorting the main messages. Second, 'mimicked scientific critique' was used to undermine evidence; this form of critique insisted on methodological perfection, rejected methodological pluralism, adopted a litigation (not scientific) model, and was not rigorous. Third, TTCs engaged in 'evidential landscaping', promoting a parallel evidence base to deflect attention from SP and excluding company-held evidence relevant to SP. The study's sample was limited to sub-sections of two out of four submissions, but leaked industry documents suggest at least one other company used a similar approach. CONCLUSIONS: The TTCs' claim that SP will not lead to public health benefits is largely without foundation. The tools of Better Regulation, particularly stakeholder consultation, provide an opportunity for highly resourced corporations to slow, weaken, or prevent public health policies.

La restriction de l’usage du tabac en prison au Québec : effets sur le climat carcéral

L’objectif principal de cet article est de mieux connaître les perceptions de personnes détenues en ce qui a trait aux effets sur le climat carcéral d’un règlement qui vise à restreindre l’usage du tabac dans les établissements de détention québécois. Une méthodologie mixte a été employée afin de recueillir des données auprès de 113 personnes détenues dans trois établissements de détention du Québec. Les données quantitatives ont été analysées de manière descriptive et comparative, alors que les données qualitatives ont fait l’objet d’une analyse thématique. Les résultats de l’étude démontrent que les personnes détenues, en désaccord pour la majorité avec l’implantation du nouveau règlement, ont perçu que son implantation a contribué à une hausse des tensions, du trafic de cigarettes et de leur valeur sur le marché noir. Selon leur position ou leur pouvoir, cette situation peut s’avérer profitable pour certains détenus alors qu’elle accroît la vulnérabilité d’autres détenus. L’hypothèse de départ voulant que l’entrée en vigueur d’un nouveau règlement sur le tabagisme entraîne des perturbations du climat carcéral est soutenue par les résultats obtenus.

Fighting a tobacco rollback : a political analysis of the 1994 contraband crisis in Canada

We identify factors that led a regional government (Quebec, Canada) to opt for a reduction of its tobacco tax to combat tobacco smuggling. Then we explore the fallout of Quebec's tobacco-tax rollback on its tobacco control policy. We conducted qualitative research using a case-study design and multiple sources of data. We applied the Advocacy Coalition Framework in respect of data collection and analysis. Advocates of the tobacco-tax rollback framed the contraband problem in a way that won the support of an array of actors. However, anti-tobacco activists succeeded in convincing the government to invest more in tobacco control. The new resources were instrumental in enhancing the activists' ability to promote legislative measures. Our approach sheds light on the tobacco industry's strategy to have governments reducing their tobacco tax. Quebec offers an example of how tobacco control activists can transform defeat into the cornerstone of a comprehensive tobacco control policy.

The rise and fall of stand-alone social reporting in a multinational subsidiary in Bangladesh:a case study

Purpose -The main aim of this paper is to examine the underlying drivers for the development and subsequent discontinuation of stand-alone corporate social responsibility (CSR) reporting in a multinational subsidiary in Bangladesh. Design/Methodology/Approach - The research approach employed for this purpose is a case study using evidence from a series of in depth interviews conducted during the period 2002-2010. Interview data is supplemented by examining other sources of information including annual reports, stand-alone social reports and relevant newspaper articles during the study period. Findings - It appears that the stand-alone CSR reporting process was initiated to give the subsidiary a formal space in which to legitimise its activities in Bangladesh where both tobacco control regulation and a strong anti-tobacco movement were gaining momentum. At the start of the process in 2002 corporate interviewees were very receptive of this initiative and strongly believed that it would not be a one off exercise. However, in the face of subsequent significant national policy shifts concerning tobacco control, irreconcilable stakeholder demands and increasing criticism of the CSR activities of the organisation at home and abroad the process was brought to an abrupt end in 2009. Research Limitations/Implications - The paper has a number of implications for policy makers concerning the future prospects for stand-alone social/sustainability reporting as a means of enhancing organisational transparency and accountability. In addition the paper discusses a number of theoretical implications for the development of legitimacy theory. Originality/value - Using the lens of legitimacy the paper theorises the circumstances leading to the initiation and subsequent cessation of CSR reporting in the organisation concerned. As far as we know this is the first study which theorises and provides significant fieldwork based empirical evidence regarding the discontinuation of stand-alone social reporting by a multinational company operating in a developing country. Thus, it extends previous desk-based attempts at using legitimacy theory to explain a decrease (or discontinuity) in CSR disclosures by de Villiers and van Staden (2006) and Tilling and Tilt (2010).

International trade law, plain packaging and tobacco industry political activity:the Trans-Pacific Partnership

Tobacco companies are increasingly turning to trade and investment agreements to challenge measures aimed at reducing tobacco use. This study examines their efforts to influence the Trans-Pacific Partnership (TPP), a major trade and investment agreement which may eventually cover 40% of the world's population; focusing on how these efforts might enhance the industry's power to challenge the introduction of plain packaging. Specifically, the paper discusses the implications for public health regulation of Philip Morris International's interest in using the TPP to: shape the bureaucratic structures and decision-making processes of business regulation at the national level; introduce a higher standard of protection for trademarks than is currently provided under the Agreement on Trade Related Aspects of Intellectual Property Rights; and expand the coverage of Investor-State Dispute Settlement which empowers corporations to litigate directly against governments where they are deemed to be in breach of investment agreements. The large number of countries involved in the TPP underlines its risk to the development of tobacco regulation globally.

Impacto das campanhas publicitárias contra o tabagismo no comportamento do consumidor

Todos os anos, milhares de pessoas morrem vítimas de doenças causadas pelo consumo de produtos derivados do tabaco, este é considerado a principal causa de morte evitável. O tabaco também colabora com as seis das oito principais causas de mortes entre fumantes e não fumantes a nível mundial. Algumas medidas governamentais como as campanhas publicitárias antitabagistas, buscam alertar, conscientizar e mudar o pensamento e o interesse coletivo neste tipo de produto e consequentemente, diminuir a taxa de consumo. Avaliar se as crenças, pensamentos e atitudes dos brasileiros são influenciados por este tipo de publicidade e se o comportamento relacionado a não fumar ou deixar de fumar é uma consequência da persuasão das mensagens antitabagistas, ajudam a conhecer o real impacto destas campanhas e sua eficácia. Através dos métodos de investigação quantitativo e qualitativo e das análises extensiva e semiótica, a pesquisa inquiriu 272 indivíduos brasileiros à respeito das advertências sanitárias e das campanhas publicitárias antitabagistas, classificando-os como não fumantes, ex-fumantes e fumantes, identificando os elementos visuais e textuais que compõem a narrativa publicitária de 5 anúncios antitabagistas. Após a análise, a pesquisa concluiu que as campanhas publicitárias coordenadas pelo INCA – Instituto Nacional de Câncer, denominadas campanhas antitabagistas, são eficazes para alertar e conscientizar os indivíduos sobre os males causados pelo consumo do cigarro mas ineficazes para influenciar suas atitudes e comportamentos. Embora estas consigam persuadir à crença nas mensagens, fazendo com que os indivíduos as vejam como verdadeira, isto não é suficiente para que a intenção de deixar de fumar torne-se um ato prático. Todos os anúncios possuem o mesmo formato e a maioria utilizou o mesmo percurso visual, equilíbrio, enquadramento, luz, ângulo e função do personagem. Todos possuem textos com funções identificadora, ancoragem e apoio e a narrativa conota o cigarro como algo negativo, prejudicial, mortífero e destruidor.

L'interdiction de fumer en établissement de détention canadien : le vécu des hommes incarcérés.

La présente étude a comme objectif de comprendre comment les détenus se sont adaptés à l’interdiction complète de fumer dans les établissements carcéraux canadiens. À partir d’entrevues qualitatives menées auprès de dix-sept hommes incarcérés dans divers établissements de détention canadiens, nous avons analysé le vécu des reclus soumis à cette nouvelle réglementation. Il ressort de nos analyses que le tabac permet aux détenus d’amoindrir les souffrances liées à l’emprisonnement, d’où l’adaptation individuelle et collective quant au contournement de la politique antitabac. De plus, la réglementation sur le tabac a des répercussions considérables sur le caractère total des institutions carcérales. La perte d’un droit qui avait été acquis depuis plusieurs décennies a créé une augmentation des mesures de contrôle, des privations et des tensions au sein du milieu carcéral.

La presión laboral tendenciosa (Mobbing)

El trabajo de investigación surge en el año 2001, ante la necesidad de hacer frente a una nueva realidad jurídica, el mobbing. Para ello fue decisivo el estudio de lo publicado (básicamente de ramas ajenas al Derecho) pero sobre todo las entrevistas con las víctimas de mobbing y sus asociaciones; este extremo, unido a la ausencia de un tratamiento internacional, obligó a un camino autodidacta para definir mobbing jurídicamente. La Tesis define mobbing como la presión laboral tendente a la autoeliminación de un trabajador mediante su denigración (presión laboral tendenciosa), y con ello por primera vez se tiene una definición de mobbing en línea y media, con plena validez jurídica, que es susceptible de ser memorizada y por lo tanto divulgada, para corregir el problema. El denominado "concepto uniformado de mobbing" recalca la denigración como mecanismo frente a los tratos degradantes y recalca la autoeliminación como finalidad de un comportamiento doloso. El trabajo aporta fórmulas para deslindar casos de mobbing de otras figuras próximas, y en este sentido debe citarse "la regla del 9" para saber si hay mobbing; en sede de estadísticas se critican metodológicamente muchas de ellas presentadas hasta el momento y se aporta alguna en sede de Tribunales; pero sobre todo se advierte de los riesgos jurídicos de una previsible regulación específica antimobbing, mediante el examen de las distintas definiciones que se han esgrimido hasta el momento. La segunda parte de la Tesis profundiza sobre el grado de sensibilización de nuestro ordenamiento jurídico y Tribunales, a cuyo fin se ha trabajado con más de un centernar y medio de sentencias dictadas sobre la materia, y por supuesto la totalidad de las recogidas en las bases de datos de las editoriales. El análisis sirve para apreciar la bondad de la sistemática aquí defendida, poniendo en evidencia errores, y contradicciones. La Tesis advierte que la presión laboral tendenciosa más allá de vulnerar el derecho constitucional al trabajo, o los derechos fundamentales a la integridad moral y el honor, es una transgresión a todo un "espíritu constitucional", y en este sentido se analiza con detalle tanto la posibilidad de recurrir en amparo, como el derecho a la indemnidad para quien se enfrenta a esta situación. Advirtiendo de las ventajas de efectuar esta reacción mediante la modalidad procesal de tutela de los derechos fundamentales, se analiza la recurrida acción del art.50 ET, donde se realizan aportaciones sugerentes como el plazo prescripción o la "doctrina de los antecedentes", y se otorgan respuestas a las preguntas sobre obligación de seguir trabajando y ejecución provisional. En sede de acciones de Seguridad Social, la Tesis distingue entre la incapacidad temporal y permanente (depresiones) y la muerte y supervivencia, aportándose sobre la primera la técnica denominada "interpretación en tres niveles" y descartando la posibilidad de considerar accidente de trabajo el suicidio tras un mobbing por imperativo legal, pero aportando un sucedáneo bastante razonable como es el accidente no laboral. Junto a ello se razona por la viabilidad del recargo del art.123 LGSS. Civilmente, la Tesis se posiciona de "lege ferenda" por reconducir este tipo de acciones resarcitorias del daño psíquico y moral al orden civil, por una mayor explicación sobre el origen del quantum, pero sobre todo considera inadmisible la STS 11-3-04, y ello por una pluralidad de argumentos, pero sobre todo por cuanto viene a autorizar "de facto" este tipo de conductas. La posibilidad de accionar administrativamente frente a este riesgo psicosocial se analiza en un doble terreno, la empresa y la Administración. Si bien el cauce sobre el primero tiene algunos meandros que se desbelan, la situación es radicalmente frustrante en la Administración -donde se encuentra el mayor caldo de cultivo del mobbing- , y ello por el RD 707/2002, pero todavía en mayor medida por el Criterio Técnico 34/2003 mediante el cual la interpretación del Director General de la Inspección de Trabajo y Seguridad Social ha venido tácitamente a derogar parcialmente la Ley de Prevención de Riesgos Laborales para la Administración. En materia penal, la Tesis se decanta "a priori" por dos tipos penales, los delitos contra los derechos de los trabajadores, y el delito de trato degradante; sin embargo, en la práctica sólo este segundo es el camino que puede alcanzar buen puerto. Finalmente se realiza un estudio detallado de la Ley 62/2003, ley que se divulgó como reguladora del acoso moral, y que después se defiende como un avance frente al mobbing. La Tesis advierte que no es cierto ni lo uno, ni lo otro, habiendo creado un "espejismo legal" que puede perjudicar a las víctimas de mobbing, además de no servir su estructura para una futura regulación explícita antimobbing.

Doping in sport: an economic analysis

This paper examines the impact of various regulatory policies on the decision to dope by athletes. The analysis suggests that punishment schemes involving lump-sum fines and bans, which are commonly used to control doping, create biases, and do not achieve their goal of levelling the playing field. Under plausible assumptions, these schemes are more likely to control doping for risk averse athletes compared to risk neutral ones, poorer athletes compared to their wealthier counterparts, and athletes with high earning potentials relative to those with lower potential. A marginal penalty scheme where athletes are fined based on the quantity of dope detected eliminates these biases, and emerges as a superior policy for levelling the playing field.

Lifestyle factors, direct and indirect costs for a Brazilian airline company

OBJECTIVE: To analyze lifestyle risk factors related to direct healthcare costs and the indirect costs due to sick leave among workers of an airline company in Brazil. METHODS: In this longitudinal 12-month study of 2,201 employees of a Brazilian airline company, the costs of sick leave and healthcare were the primary outcomes of interest. Information on the independent variables, such as gender, age, educational level, type of work, stress, and lifestyle-related factors (body mass index, physical activity, and smoking), was collected using a questionnaire on enrolment in the study. Data on sick leave days were available from the company register, and data on healthcare costs were obtained from insurance records. Multivariate linear regression analysis was used to investigate the association between direct and indirect healthcare costs with sociodemographic, work, and lifestyle-related factors. RESULTS: Over the 12-month study period, the average direct healthcare expenditure per worker was US$505.00 and the average indirect cost because of sick leave was US$249.00 per worker. Direct costs were more than twice the indirect costs and both were higher in women. Body mass index was a determinant of direct costs and smoking was a determinant of indirect costs. CONCLUSIONS: Obesity and smoking among workers in a Brazilian airline company were associated with increased health costs. Therefore, promoting a healthy diet, physical activity, and anti-tobacco campaigns are important targets for health promotion in this study population.

Tabagisme et défavorisation de quartier : étude exploratoire des expériences de stigmatisation chez les jeunes femmes

La prévalence du tabagisme a diminué dans les dernières décennies, mais les inégalités sociales reliées au tabagisme s’accentuent. Les stratégies de dénormalisation du tabagisme ont amené la stigmatisation des fumeurs. Le lien entre celle-ci et la défavorisation de quartier est mal compris. Cette étude qualitative a comparé les expériences de stigmatisation de quinze jeunes femmes fumeuses dont la moitié vivait dans des quartiers très défavorisés de Montréal et l’autre moitié résidait dans les quartiers les moins défavorisés. Dans ces derniers, stigmatiser les fumeurs fait partie de la norme. Le tabagisme est vu comme un symbole de pauvreté, entraînant l’utilisation de stratégies pour se distancer du stigma. Dans les quartiers défavorisés, les participantes rapportaient une stigmatisation basée sur le genre et elles tentaient d’y échapper en se cachant pour fumer. Les résultats mettent en lumière les effets non attendus des politiques anti-tabac et pourraient contribuer au développement de politiques plus équitables.
