Gradientes radiais de abundância são observados no disco de nossa Galáxia e também em outras galáxias espirais. No caso da Galáxia, o principal problema relativo aos gradientes é sua variação temporal, que constitui um dos principais vínculos aos modelos de evolução química da Galáxia. As nebulosas planetárias são particularmente interessantes no estudo dos gradientes e suas variações, tanto espaciais como temporais. São objetos brilhantes, podendo ser observadas a grandes distâncias, e têm abundâncias relativamente precisas de diversos elementos químicos. Além disso, sendo originadas de estrelas com massas entre 0.8 e 8 massas solares na sequência principal, incluem objetos com idades e populações diferentes, o que as torna especialmente interessantes ao estudo da variação temporal dos gradientes. Neste trabalho, apresentamos resultados recentes sobre a variação temporal do gradiente de O/H a partir de uma amostra contendo cerca de 200 nebulosas, para as quais obtivemos distâncias por métodos estatísticos. As abundâncias foram parcialmente obtidas a partir de observações em Itajubá e La Silla, sendo as restantes obtidas da literatura. Os resultados mostram, pela primeira vez, evidências de um achatamento do gradiente de O/H, de -0.11 dex/kpc para -0.06 dex/kpc nos últimos 9 giga-anos ou de -0.08 dex/kpc para -0.06 dex/kpc nos últimos 5 giga-anos. Esses valores apresentam um bom acordo com alguns modelos recentes para a evolução química da Galáxia. (FAPESP/CNPq)

Traditional Chinese medicine (TCM) is commonly provided to cancer patients, however, the patterns of prescriptions for this type of medicine in Taiwan are unclear. This study aimed to evaluate the use of traditional Chinese medicine products in colon cancer patients post-surgery in Taiwan and to research patterns of TCM. This was a cross-sectional study of newly diagnosed colon cancer patients who received surgery between 2004 and 2008 identified from the National Health Insurance Research Database of Taiwan. The prescription patterns and reasons for the use of TCM for colon cancer were analyzed. The results showed that "symptoms, signs and ill-defined conditions" (23.3%) and diseases of the digestive system (16.9%) were the most common reasons for using Chinese herbal medicine. Xiang-sha-liu-jun-zi-tang (7.1%), Bu-zhong-yi-qi-tang (4.3%), Jia-wei-xiao-yao-san (4.1%), Shen-Ling-Bai-Zhu-San (3.7%), Ban-Xia-Xie-Xin-Tang (3.4%), Gui-pi-tang (2.4%), Ping-Wei-San (2.4%), Gan-Lu-Yin (2.0%), Bao-He-Wan (1.9%), and Zhen-Ren-Huo-Ming-Yin (1.8%) were the most commonly prescribed single Chinese herbal formulae (CHF) for colon cancer patients post-surgery. Hedyotis diffusa Willd (Bai Hua She She Cao) (5.1%) and Scutellaria barbata (Ban Zhi Lian )(4.8%) were the most commonly prescribed single Chinese herbs. This study identified patterns of TCM use in colon cancer patients post-surgery in Taiwan. The herbal ingredients were most commonly used for stimulate ghrelin secretion to increase food intake and had potential anti-tumor effect. However, further research is required to evaluate any beneficial effects which could identify leads for the development of new treatment strategies using TCM. Copyright © 2014 Elsevier Ireland Ltd.

Campo de velocidade peculiar na teoria linear

NASA Astrophysics Data System (ADS)

Pires, N.

2003-08-01

Aglomerados e superaglomerados de galáxias são responsáveis pela chamada velocidade peculiar (movimentos relativos à expansão pura do universo) das galáxias. A amplitude destas perturbações depende da densidade de matéria do universo e do contraste de densidade no interior do volume onde está localizada a galáxia. Em 1980, Peebles introduziu o fator "f", que relaciona a amplitude das perturbações da velocidade com o campo gravitacional peculiar, no contexto da teoria linear. No presente trabalho obtemos uma solução geral analítica para o fator "f" de Peebles do campo de velocidades peculiares, em termos de funções hipergeométricas, válida para qualquer geometria do universo. Como um teste de nossa solução, os resultados encontrados originalmente por Peebles em 1980 e os resultados mais gerais encontrados por O. Lahav e colaboradores em 1991, são reobtidos.

Smoking bans are considered one of the most effective policies to reduce population exposure to tobacco smoke and prevent adverse health outcomes. However, evidence on the effect of contextual variables on the effectiveness of smoking bans is still lacking. The patchwork of cantonal smoke-free laws in Switzerland was used as a quasi-experimental setting to assess changes after their introduction in: hospitalisations and mortality due to cardiorespiratory diseases in adults; total hospitalisations and hospitalisations due to respiratory disorders in children; and the modifying effects of contextual factors and the effectiveness of the laws. Using hospital and mortality registry data for residents in Switzerland (2005-2012), we conducted canton-specific interrupted time-series analyses followed by random effects meta-analyses to obtain nationwide smoking ban estimates by subgroups of age, sex and causes of hospitalisation or death. Heterogeneity of the impact caused by strictness of the ban and other smoking-related characteristics of the cantons was explored through meta-regression. Total hospitalisation rates due to cardiovascular and respiratory diseases did not significantly change after the introduction of the ban. Post-ban changes were detected in ischaemic heart disease hospitalisations, with a 2.5% reduction (95% confidence interval [CI)] -6.2 to 1.3%) for all ages and 5.5% (95% CI -10.8 to -0.2%) in adults 35-64 years old. Total mortality due to respiratory diseases decreased by 8.2% (95% CI -15.2 to -0.6%) over all ages, and chronic obstructive pulmonary disease mortality decreased by 14.0% (95% CI -22.3 to -4.5%) in adults ≥65 years old. Cardiovascular mortality did not change after the introduction of the ban, but there was an indication of post-ban reductions in mortality due to hypertensive disorders (-5.4%, 95% CI -12.6 to 2.3%), and congestive heart failure (-6.0%, 95% CI -14.5 to 3.4%). No benefits were observed for hospitalisations due to respiratory diseases in children or for infant mortality. The type of smoking ban implemented explained the heterogeneity of benefits across cantons for some outcomes. Smoking bans in Switzerland were associated with overall reductions in cardiovascular and respiratory hospitalisation and mortality in adults.

Newcastle disease virus (NDV) can cause severe disease in chickens. Although NDV vaccines exist, there are frequent reports of outbreaks in vaccinated chickens. During 2009–2010, despite intense vaccination, NDV caused major outbreaks among commercial poultry farms in Indonesia. These outbreaks raised concern regarding the protective immunity of current vaccines against circulating virulent strains in Indonesia. In this study, we investigated whether a recombinant attenuated Indonesian NDV strain could provide better protection against prevalent Indonesian viruses. A reverse genetics system for the highly virulent NDV strain Banjarmasin/010/10 (Ban/010) isolated in Indonesia in 2010 was constructed. The Ban/010 virus is classified in genotype VII of class II NDV, which is genetically distinct from the commercial vaccine strains B1 and LaSota, which belong to genotype II, and shares only 89 and 87% amino acid identity for the protective antigens F and HN, respectively. A mutant virus, named Ban/AF, was developed in which the virulent F protein cleavage site motif “RRQKR↓F” was modified to an avirulent motif “GRQGR↓L” by three amino acid substitutions (underlined). The Ban/AF vaccine virus did not produce syncytia or plaques in cell culture, even in the presence of added protease. Pathogenicity tests showed that Ban/AF was completely avirulent. Ban/AF replicated efficiently during 10 consecutive passages in chickens and remained genetically stable. Serological analysis showed that Ban/AF induced higher neutralization and hemagglutination inhibition antibody titers against the prevalent viruses than the commercial vaccines B1 or LaSota. Both Ban/AF and commercial vaccines provided protection against clinical disease and mortality after challenge with virulent NDV strain Ban/010 (genotype VII) or GB Texas (genotype II). However, Ban/AF significantly reduced challenge virus shedding from the vaccinated birds compared to B1 vaccine. These results suggest that Ban/AF can provide better protection than commercial vaccines and is a promising vaccine candidate against NDV strains circulating in Indonesia. PMID:23285174

Massa do gás e das estrelas em aglomerados: eficiência da formação estelar

NASA Astrophysics Data System (ADS)

Laganá, T. F.; Lima Neto, G. B.

2003-08-01

Os aglomerados de galáxias apresentam um interesse especial para a cosmologia observacional. Eles são as maiores estruturas ligadas pela gravitação no Universo e relaxadas na região central. A comparação entre a massa do gás intra-aglomerado (responsável por ~25% da massa total, inferida a partir de observações em raios-X), a massa contida nas estrelas (i.e., nas galáxias) e a massa total (incluindo a matéria escura não bariônica), nos dá informações importantes sobre os processos de formação e evolução de aglomerados. Por exemplo, a razão entre a massa do gás e a massa total é uma medida da fração de bárions no Universo (razão entre a matéria bariônica e matéria escura) e, utilizando a densidade de bárions predita pela nucleosíntese primordial, podemos deduzir a densidade de matéria escura no Universo (cf. White et al. 1993). O objetivo deste trabalho é obter as razões entre as massas do gás, estelar (contida nas galáxias), e a total (massa dinâmica). As massas do gás e total são obtidas a partir das análises fotométrica e espectroscópica em raios-X enquanto que a massa estelar é obtida pela análise fotométrica das galáxias. Esta análise foi aplicada ao aglomerado Abell 496 observado pelo satélite XMM-Newton. A massa contida nas galáxias foi estimada a partir da função de luminosidade obtida por Durret et al. (2002). Para determinar as massas dinâmica e do gás nos precisamos determinar os perfis radiais de densidade e temperatura. Nós apresentaremos aqui estes resultados e suas implicações na eficiência da formação estelar em Abell 496.

Espectroscopia multi-objeto e imageamento de Abell 586 com GMOS - o estado dinâmico de um aglomerado de galáxias com arcos gravitacionais

Nesse trabalho é apresentado um estudo do conteúdo de massa do aglomerado de galáxias A586 (z = 0.171) bem como sua distribuição espacial. Isso foi feito a partir de dados de espectroscopia multi-objeto e imageamento obtidos com o instrumento GMOS acoplado ao telescópio Gemini-Norte. A massa desse aglomerado foi estudada a partir da posição dos seus arcos gravitacionais (lentes fortes), da medida estatística da distorção na forma das galáxias de fundo (lentes fracas) e através da dispersão de velocidades de uma amostra de cerca de 30 galáxias pertencentes ao aglomerado (teorema do virial). Os dois primeiros métodos não dependem do estado dinâmico do aglomerado, enquanto que o terceiro sim. Desse modo, comparando seus resultados pode-se estimar o grau de relaxamento desse sistema. Dados de raios X presentes na literatura também serão incluídos nessa análise. Nossos resultados preliminares a partir das técnicas de lentes fracas, mostram que, supondo que a distribuição de massa desse aglomerado seja a de uma esfera isotérmica, espera-se que ele apresente uma dispersão de velocidades de 1330+/-78 km s-1, em contradicao com medidas similares feitas por Dahle et al. 2002 que encontram valores tão altos quanto 1680 km s-1. Já o estudo dinâmico resultou numa dispersão de velocidades de ~950 km s-1.

Gradientes de abundâncias em galáxias espirais

Dors, O. L.., Jr.; Copetti, M. V. F.

2003-08-01

Gradientes de abundâncias obtidos através de observações de regiões H II têm um papel importante no estudo de formação e evolução de galáxias espirais. Determinações diretas de abundâncias somente são obtidas quando linhas de emissão sensíveis à temperatura eletrônica (e.g., [O III]l4363) são detectadas. Infelizmente estas linhas são fracas ou não observadas em regiões H II de baixa excitação. Nestes casos métodos empíricos são utilizados para estimar as abundâncias químicas. Entretanto, diferentes métodos têm produzido diferentes estimativas de gradientes de abundâncias. Neste trabalho, nós construímos modelos de fotoionização com o objetivo de descrever diagramas de diagnósticos construídos com dados publicados de algumas galáxias espirais normais e barradas. Comparações entre nossas estimativas de abundâncias e de outros métodos mostram que quando não há acordo entre eles, nossos modelos superestimam as abundâncias de O/H e N/H por um fator de 0.3 dex em relação a estimativas diretas de abundâncias, e por fator de 0.2 dex em relação a outros métodos empíricos. A origem da produção de nitrogênio nas galáxias estudadas é discutida.

Contagem de fontes de radio na direção de aglomerados ricos de galaxias

NASA Astrophysics Data System (ADS)

Andreazza, C. M.; Andernach, H.

A contagem de fontes de rádio, na direção de aglomerados ricos de galáxias, deve fornecer uma distribuçãto acima da média do campo devido aos efeitos do meio. No entanto, a distribução de radiofontes de alguns aglomerados, investigada por vários autores no passado, mostrou, em alguns casos, uma deficência de fontes fracas. Neste trabalho, analisamos os levantamentos em 2.7 GHz (Reuter e Andernach 1990, 1990A&AS...82..279R; Loiseau et al. 1988, 1988A&AS...75...67L) e o catálogo 6CII em 151 MHz (Hales et al. 1988, 1988MNRAS.234..919H). Nosso estudio da distribução de radiofontes, na direção de aglomerados ricos de galáxias, nestas duas frequências, mostra um excesso de fontes fortes somente nas regiões centrais dos aglomerados. Este resultado pode ser explicado devido à evidência de confinamento das radiofontes pelo gás, do meio intra-aglomerado, e devido aos processos de colisão, coalescência e canibalismo de galáxias.

General purpose pulse shape analysis for fast scintillators implemented in digital readout electronics

NASA Astrophysics Data System (ADS)

Asztalos, Stephen J.; Hennig, Wolfgang; Warburton, William K.

2016-01-01

Pulse shape discrimination applied to certain fast scintillators is usually performed offline. In sufficiently high-event rate environments data transfer and storage become problematic, which suggests a different analysis approach. In response, we have implemented a general purpose pulse shape analysis algorithm in the XIA Pixie-500 and Pixie-500 Express digital spectrometers. In this implementation waveforms are processed in real time, reducing the pulse characteristics to a few pulse shape analysis parameters and eliminating time-consuming waveform transfer and storage. We discuss implementation of these features, their advantages, necessary trade-offs and performance. Measurements from bench top and experimental setups using fast scintillators and XIA processors are presented.

Busca de estruturas em grandes escalas em altos redshifts

Boris, N. V.; Sodré, L., Jr.; Cypriano, E.

2003-08-01

A busca por estruturas em grandes escalas (aglomerados de galáxias, por exemplo) é um ativo tópico de pesquisas hoje em dia, pois a detecção de um único aglomerado em altos redshifts pode por vínculos fortes sobre os modelos cosmológicos. Neste projeto estamos fazendo uma busca de estruturas distantes em campos contendo pares de quasares próximos entre si em z Â3 0.9. Os pares de quasares foram extraídos do catálogo de Véron-Cetty & Véron (2001) e estão sendo observados com os telescópios: 2,2m da University of Hawaii (UH), 2,5m do Observatório de Las Campanas e com o GEMINI. Apresentamos aqui a análise preliminar de um par de quasares observado nos filtros i'(7800 Å) e z'(9500 Å) com o GEMINI. A cor (i'-z') mostrou-se útil para detectar objetos "early-type" em redshifts menores que 1.1. No estudo do par 131046+0006/J131055+0008, com redshift ~ 0.9, o uso deste método possibilitou a detecção de sete objetos candidatos a galáxias "early-type". Num mapa da distribuição projetada dos objetos para 22 < i' < 25 observou-se que estas galáxias estão localizadas próximas a um dos quasares e há indícios de que estejam aglomeradas dentro de um área de ~ 6 arcmin2. Se esse for o caso, estes objetos seriam membros de uma estrutura em grande escala. Um outro argumento em favor dessa hipótese é que eles obedecem uma relação do tipo Kormendy (raio equivalente X brilho superficial dentro desse raio), como a apresentada pelas galáxias elípticas em z = 0.

A distribuição de velocidades na linha de visada em galáxias barradas vistas de face

Gadotti, D. A.; de Souza, R. E.

2003-08-01

Com o objetivo de realizar um estudo cinemático da componente vertical de barras em galáxias, obtivemos espectros de fenda longa de alta razão S/N ao longo dos eixos maior e menor de 14 galáxias barradas vistas de face, nos telescópios de 1.52m do ESO em La Silla, Chile, e de 2.3m do Steward Observatory em Kitt Peak, Arizona. Estes dados nos permitiram determinar a distribuição de velocidades das estrelas ao longo do eixo vertical das barras e discos destes sistemas, tanto no centro como em pontos que distam cerca de 5 e 20 segundos de arco do núcleo, correspondendo a distâncias de cerca de 0.7 e 2.8 kpc, respectivamente. Desta forma, a variação radial da distribuição de velocidades também pôde ser avaliada. Este tipo de análise tem raros exemplos na literatura por ser caro em termos de tempo de telescópio. Entretanto, é de fácil justificativa, considerando que traz novas informações que podem ser utilizadas para aperfeiçoar modelos teóricos acerca da formação e evolução de galáxias. Um algoritmo por nós desenvolvido foi utilizado para obter as distribuições de velocidades como Gaussianas generalizadas (polinômios de Gauss-Hermite), o que traz um ingrediente a mais neste tipo de estudo que, tradicionalmente, se utiliza de Gaussianas puras, uma hipótese nem sempre razoável. Apresentaremos os resultados deste trabalho, que incluem um diagnóstico para a identificação de barras recém formadas, e testes para o modelo isotérmico de discos. Mostraremos que: (i) a escolha das estrelas padrão em velocidade, e dos parâmetros da Gaussiana, deve ser muito bem justificada já que tem influência significativa nos resultados; (ii) muitas galáxias apresentam uma depressão na dispersão de velocidades na região central, que pode estar associada a um disco interno; e (iii) a dispersão de velocidades é constante ao longo da barra, nos eixos maior e menor, mas cai substancialmente quando se passa da barra para o disco.

From discard ban to exemption: How can gear technology help reduce catches of undersized Nephrops and hake in the Bay of Biscay trawling fleet?

PubMed

Vogel, Camille; Kopp, Dorothée; Méhault, Sonia

2017-01-15

On January 1st, 2016, the French mixed Nephrops and hake fishery of the Grande Vasière, an area located in the Bay of Biscay, fell under the discard ban implemented as part of the new European Common Fisheries Policy. The fleet records historically high levels of discard despite numerous gear selectivity studies. Together with high discards survival, new technological solutions to minimize catches of undersized individuals could justify local exemptions from the discard ban. Our study focuses on the effects of two selective devices, a square mesh cylinder (SMC) and a grid, on the escapement of undersized individuals and discard reduction. Relative catch probability of the modified gear compared with the traditional gear was modelled using the catch comparison method. Potential losses from the commercial fraction of the catch were taken into account to assess their influence on the economic viability of fishing with the modified gears. The two devices had similar effects on undersized Nephrops escapement and on discard reduction, with median values of 26.5% and 23.6% for the SMC and of 30.4% and 21.4% for the grid, respectively. Only the grid was efficient for undersized hake, recording median values of escapement and discard reduction equal to 25.0% and 20.6%, respectively. Some loss from the commercial fraction of the catch was to be expected with both devices, which could be compensated for in the long term by the contribution of undersized individuals to the stock biomass. Our results support the use of selective gears technology as part of an integrated framework including control and management measures to mitigate the effect of the discard ban both for fishers and for the ecosystem. Further work is needed to quantify the effect of additional escapement from the gear on stock dynamics. Copyright © 2016 Elsevier Ltd. All rights reserved.

Structural Principles in the Development of Cyclic Peptidic Enzyme Inhibitors

PubMed Central

Xu, Peng; Andreasen, Peter A.; Huang, Mingdong

2017-01-01

This review summarizes our studies in the development of small cyclic peptides for specifically modulating enzyme activity. Serine proteases share highly similar active sites but perform diverse physiological and pathological functions. From a phage-display peptide library, we isolated two mono-cyclic peptides, upain-1 (CSWRGLENHRMC) and mupain-1 (CPAYSRYLDC), which inhibit the activity of human and murine urokinase-type plasminogen activators (huPA and muPA) with Ki values in the micromolar or sub-micromolar range, respectively. The following affinity maturations significantly enhanced the potencies of the two peptides, 10-fold and >250-fold for upain-1 and mupain-1, respectively. The most potent muPA inhibitor has a potency (Ki = 2 nM) and specificity comparable to mono-clonal antibodies. Furthermore, we also found an unusual feature of mupain-1 that its inhibitory potency can be enhanced by increasing the flexibility, which challenges the traditional viewpoint that higher rigidity leading to higher affinity. Moreover, by changing a few key residues, we converted mupain-1 from a uPA inhibitor to inhibitors of other serine proteases, including plasma kallikrein (PK) and coagulation factor XIa (fXIa). PK and fXIa inhibitors showed Ki values in the low nanomolar range and high specificity. Our studies demonstrate the versatility of small cyclic peptides to engineer inhibitory potency against serine proteases and to provide a new strategy for generating peptide inhibitors of serine proteases.

Neste trabalho, a formação estelar e evolução quí mica em galáxias Compactas Azuis (Blue Compact Galaxies - BCGs) foram estudadas através da comparação de previsões de modelos de evolução quí mica a várias razões de abundância quí mica observadas nestas galáxias. Modelos detalhados com recentes dados de nucleossí ntese e que levam em consideração o papel desempenahdo por supernovas de ambos os tipos (II e Ia) na evolução galáctica foram desenvolvidos para as BCGs permitindo seguir a evolução de vários elementos quí micos (H, D, He, C, N, O, Mg, Si, S, Ca, e Fe). O modelo é caracterizado pelas prescrições adotadas para a formação estelar, a qual ocorre em vários surtos de atividade separados por longos perí odos quiescentes. Após ajustar os melhores modelos aos dados observacionais, as previsões destes modelos foram comparadas também a razões de abundância observadas em sistemas Damped Lyman alpha (DLAs) e a origem do N (primária ou secundária) foi discutida. Alguns dos resultados obtidos são: i) as razões de abundância observadas nas BCGs são reproduzidas por modelos com 2 a 7 surtos de formação estelar com eficiência entre n = 0.2-0.9 Gano-1; ii) os baixos valores de N/O observados nestas galáxias são um resultado natural de uma formação estelar em surtos; iii) os modelos para BCGs podem reproduzir os dados dos DLAs, iv) uma quantidade "baixa" de N primário produzido em estrelas de alta massa pode ser uma explicação para os baixos valores de [N/a] observados em DLAs.

Tanning bed and nail lamp use and the risk of cutaneous malignancy: a review of the literature.

PubMed

O'Sullivan, Niamh-Anna; Tait, Clare P

2014-05-01

Malignant melanoma (MM) and non-melanoma skin cancer (NMSC) are increasingly common and both can be fatal. In 2009 the World Health Organization (WHO) classified the whole ultraviolet spectrum and tanning beds as carcinogenic to humans, placing them in the same category as asbestos and tobacco. Despite this, the trend for indoor tanning continues. A growing body of evidence has now associated indoor tanning with an increased risk of MM and NMSC. As a result, there has been an upsurge in regulations in the tanning industry ranging from age restrictions to complete bans on commercial tanning. This article examines the evidence and strengthens the case for a complete ban of a recognised modifiable risk factor for cutaneous malignancy. © 2014 The Australasian College of Dermatologists.

Bacterial Synthesis of Unusual Sulfonamide and Sulfone Antibiotics by Flavoenzyme-Mediated Sulfur Dioxide Capture.

Baunach, Martin; Ding, Ling; Willing, Karsten; Hertweck, Christian

2015-11-02

Sulfa drugs, such as sulfonilamide and dapsone, are classical antibiotics that have been in clinical use worldwide. Despite the relatively simple architectures, practically no natural products are known to feature such aromatic sulfonamide or diarylsulfone substructures. We report the unexpected discovery of three fully unprecedented, sulfonyl-bridged alkaloid dimers (sulfadixiamycins A-C) from recombinant Streptomyces species harboring the entire xiamycin biosynthesis gene cluster. Sulfadixiamycins exhibit moderate antimycobacterial activities and potent antibiotic activities even against multidrug-resistant bacteria. Gene inactivation, complementation, and biotransformation experiments revealed that a flavin-dependent enzyme (XiaH) plays a key role in sulfadixiamycin biosynthesis. XiaH mediates a radical-based, three-component reaction involving two equivalents of xiamycin and sulfur dioxide, which is reminiscent of radical styrene/SO2 copolymerization. © 2015 WILEY-VCH Verlag GmbH & Co.

Review article: Herbal hepatotoxicity--an update on traditional Chinese medicine preparations.

PubMed

Teschke, R; Wolff, A; Frenzel, C; Schulze, J

2014-07-01

Although evidence for their therapeutic efficacy is limited, herbal traditional Chinese medicine (TCM) preparations increasingly gain popularity. In contrast to other herbal products, adverse effects by herbal TCM including liver toxicity were rarely reported. In recent years, more cases were published, providing new clinical challenges. To summarise comprehensively the literature on herbal TCM hepatotoxicity since 2011. PubMed was searched using key words related to TCM, the results were restricted to full English-language publications and abstracts published since 2011. In addition, the database of the National Institutes of Health (NIH) and LiverTox was accessed under the topic 'Drug record: Chinese and other Asian herbal medicines'. Since 2011, new case reports and case series provided evidence for herbal hepatotoxicity by TCM, focusing on nine TCM herbal mixtures and four individual TCM herbs with potential health hazards. These were the TCM products Ban Tu Wan, Chai Hu, Du Huo, Huang Qin, Jia Wei Xia Yao San, Jiguja, Kamishoyosan, Long Dan Xie Gan Tang, Lu Cha, Polygonum multiflorum products, Shan Chi, 'White flood' containing the herbal TCM Wu Zhu Yu and Qian Ceng Ta, and Xiao Chai Hu Tang. Other developments include the establishment of a new and early diagnostic serum marker for hepatotoxicity caused by pyrrolizidine alkaloids, assessed using ultra performance liquid chromatography-mass spectrometry analysis, and new regulatory details to improve herbal TCM product quality and safety. Stringent evaluation of the risk/benefit ratio is essential to protect traditional Chinese medicines users from health hazards including liver injury. © 2014 John Wiley & Sons Ltd.

A importância deste trabalho deve-se à seleção de objetos ainda não tratados particularmente como uma família e ao emprego de procedimento estatístico robusto que não precisa de pressupostos ou condições de contorno. Contribui, assim, ao melhor entendimento do cenário das Galáxias Aneladas do diagrama de Hubble via classificação e estudo de subclasses. Selecionaram-se 100 galáxias possuidoras de dois anéis do Catalog of Southern Ringed Galaxies compilado por Ronald Buta, de modo a construir uma amostra completa em termos de conhecimento dos semi-eixos dos anéis interno e externo projetados no plano do céu. Visando uma possível classificação destas galáxias aneladas normais em famílias de acordo com as características geométricas dos anéis, empregou-se primeiramente a Análise de Aglomerados (ferramenta de classificação: medições de semelhança em um espaço bidimensional) para explorar a possível existência de famílias. As variáveis analisadas foram: os diâmetros interiores menores d(I) e maiores D(I), os diâmetros exteriores menores d(E) e maiores D(E), e os ângulos de inclinação dos semi-eixos maiores interiores q(I) e exteriores q(E) dos anéis. Como metodologia de discriminação, empregou-se a construção de Árvores de Classificação. As árvores de classificação constituem um método de discriminação alternativo aos modelos clássicos, tais como a Análise Discriminante e a Regressão Logística, onde uma base de dados é dividida em partições (subgrupos) da árvore por ação de um predictor (variável específica). Os pacotes estatísticos utilizados para o processamento da informação foram: SAS versão 8.0 (Statistical Analisys System) e CART versão 3.6.3. Esta análise estatística sugere a existência de três possíveis famílias de galáxias bianeladas, com base apenas na geometria dos anéis. Como forma exploratória inicial deste resultado, a construção de um diagrama BT (magnitude total) versus o índice de cor (B-R), mostra que os três grupos distribuem-se de forma praticamente contínua, porém discriminadas entre si, ocupando três regiões distintas. A classe 3, por exemplo, é geralmente a mais azul, sendo a Classe 1 a mais avermelhada.

Inhibition of factor XIa (FXIa) is a novel paradigm for developing anticoagulants without major bleeding consequences. We present the discovery of sulfated pentagalloylglucoside (6) as a highly selective inhibitor of human FXIa. Biochemical screening of a focused library led to the identification of 6, a sulfated aromatic mimetic of heparin. Inhibitor 6 displayed a potency of 551 nM against FXIa, which was at least 200-fold more selective than other relevant enzymes. It also prevented activation of factor IX and prolonged human plasma and whole blood clotting. Inhibitor 6 reduced VMAX of FXIa hydrolysis of chromogenic substrate without affecting the KM suggesting an allosteric mechanism. Competitive studies showed that 6 bound in the heparin-binding site of FXIa. No allosteric small molecule has been discovered to date that exhibits equivalent potency against FXIa. Inhibitor 6 is expected to open up a major route to allosteric FXIa anticoagulants with clinical relevance. PMID:23316863

Tissue-specific production of limonene in Camelina sativa with the Arabidopsis promoters of genes BANYULS and FRUITFULL.

Borghi, Monica; Xie, De-Yu

Arabidopsis promoters of genes BANYULS and FRUITFULL are transcribed in Camelina. They triggered the transcription of limonene synthase and induced higher limonene production in seeds and fruits than CaMV 35S promoter. Camelina sativa (Camelina) is an oilseed crop of relevance for the production of biofuels and the plant has been target of a recent and intense program of genetic manipulation aimed to increase performance, seed yield and to modify the fatty acid composition of the oil. Here, we have explored the performance of two Arabidopsis thaliana (Arabidopsis) promoters in triggering transgene expression in Camelina. The promoters of two genes BANYULS (AtBAN pro ) and FRUITFULL (AtFUL pro ), which are expressed in seed coat and valves of Arabidopsis, respectively, have been chosen to induce the expression of limonene synthase (LS) from Citrus limon. In addition, the constitutive CaMV 35S promoter was utilized to overexpress LS in Camelina . The results of experiments revealed that AtBAN pro and AtFUL pro are actively transcribed in Camelina where they also retain specificity of expression in seeds and valves as previously observed in Arabidopsis. LS induced by AtBAN pro and AtFUL pro leads to higher limonene production in seeds and fruits than when the CaMV 35S was used to trigger the expression. In conclusion, the results of experiments indicate that AtBAN pro and AtFUL pro can be successfully utilized to induce the expression of the transgenes of interest in seeds and fruits of Camelina.

GMO Reignited in Science but Not in Law: A Flawed Framework Fuels France's Stalemate.

Robbins, Patricia B

2014-01-01

Following a statement released by a multitude of prominent scientists contesting the idea that there is a consensus on the safety of genetically modified organisms ("GMO"), this article addresses the European Union's ("EU") GMO regulatory framework, which has reluctantly permitted France to maintain an illegal ban on. MON8 10 for over a decade now. It notes that while the statement did nothing more than reignite the debate on GMO, much could and should be done to improve the framework to accommodate for the lack of true scientific understanding about the effects of GMO. This article identifies the specific areas of weakness in the EU GMO regulatory framework and recommends specific alterations. It concludes that although France's MON810 ban is illegal under existing law, the country's fears are neither unfounded nor unsupported and that the EU should work to alter its existing legal structure to parallel today's scientific uncertainty regarding GMO safety.

Traditional Chinese medicine (TCM), when given for symptom relief, has gained widespread popularity among migraine patients. The aim of this study is to analyze the utilization of TCM among migraine patients in Taiwan. The usage, frequency of service, and the Chinese herbal products prescribed for migraine were evaluated using a representative sample of one million subjects selected at random from the 22 million beneficiaries of the National Health Insurance scheme of Taiwan. Overall, 89.3% (N=12,827) migraine patients utilized TCM and 24.2% of them sought TCM with the intention of treating their migraine-related symptoms. Migraine patients who are living in urban area and those with an episodic migraine pattern (<15 days/month) (aOR=3.18, 95% CI: 2.75-3.67) were more likely to be TCM users than those living in a rural area and those who suffered from chronic migraine (≥15 days/month) (aOR=1.00). Overall, 81.2% of TCM visits involved the prescription of a Chinese herbal remedy or remedies and Chuan-Xiong-Cha-Tiao-San, Jia-Wei-Xiao-Yao-San, Ge-Gen-Tang, Xue-Fu-Zhu-Yu-Tang, Ban-Xia-Bai-Zhu-Tian-Ma-Tang, Qing-Shang-Juan-Tong-Tang, Xiao-Chai-Hu-Tang, Tian-Ma-Gou-Teng-Yin, Bu-Zhong-Yi-Qi-Tang, and Tian-Wang-Bu-Xin-Dan were the ten most frequently prescribed formula for treating migraine based on syndrome differentiation. Chuan-Xiong-Cha-Tiao-San, which contains sedative and anti-inflammatory agents, is the most commonly prescribed Chinese herbal formula for the treatment of migraine-related phenomena.

2003-08-01

Observações em raios-X revelam o "coração" dos núcleos ativos de galáxias, pois esse tipo de radiação provém das suas regiões mais internas, próximas ao buraco negro central. Neste trabalho apresentamos observações em raios-X da região central da galáxia NGC1097, que hospeda um buraco negro supermassivo e um disco de acreção cuja emissão vem sendo observada há dez anos através da linha de emissão Ha larga (10000 km/s) e de duplo pico. As observações em raios-X - que foram obtidas com o Telescópio Chandra - foram combinadas com observações no ultravioleta obtidas com o Telescópio Espacial Hubble e são usadas para estudar as características da fonte central que ioniza o disco de acreção. A distribuição espectral de energia é comparada com a predita por modelos, em particular o de uma estrutura "ADAF" ("advection dominated accretion flow") na parte interna do disco. Tal estrutura produz um espectro de emissão de linhas estreitas tipo LINER, como observado em NGC1097 e em rádio-galáxias que apresentam linhas de Balmer largas de duplo pico. Apresentamos também uma comparação entre outros LINERs com linhas de emissão largas de duplo pico, disponíveis na literatura ou nos arquivos do Chandra e do Telescópio Espacial Hubble e discutimos as correspondentes implicações para modelos da fonte central.

To assess the impact of a partial smoking ban followed by a total smoking ban in a psychiatric hospital in Switzerland. In 2003, smoking was allowed everywhere in psychiatric units. In 2004, smoking was prohibited everywhere except in smoking rooms. In 2006, smoking rooms were removed and smoking was totally prohibited indoors. Patients and staff were surveyed in 2003 (n=106), 2004 (n=108), 2005 (n=119) and 2006 (n=134). Exposure to environmental tobacco smoke (ETS) decreased after the partial ban and further decreased after the total ban. Among patients, after the total ban, more smokers attempted to quit smoking (18%) relative to before the total ban (2%, odds ratio=10.1, p=0.01). More smokers said that hospital staff gave them nicotine replacement products after the total ban (52%), compared with before (13%, odds ratio=7.6, p<0.001). Many participants (55%) commented that the total ban was too strict, and most (64%) preferred the partial ban. The partial ban decreased exposure to ETS and the total ban further improved the situation and increased the proportion of smokers who attempted to quit smoking and received nicotine medications. The total ban was loosely enforced and was overall acceptable, but most participants preferred a partial ban.

The Spanish tobacco control law of 2006 was modified in January 2011, banning smoking in all hospitality venues. The objective of the study was to assess the impact of the 2011 Spanish smoking ban on secondhand smoke (SHS) exposure in hospitality venues, and to analyze the potential impact of outdoor smokers close to entrances on indoor SHS levels after the law came into force. Before-and-after evaluation study with repeated measures. The study was carried out in three regions of Spain (Catalonia, Galicia, and Madrid) and included a random sample of 178 hospitality venues. We measured vapor-phase nicotine and particulate matter 2.5 micrometers or less in diameter (PM2.5) as SHS markers at baseline (November-December 2010) and at follow-up (April-June 2011). We also recorded tobacco consumption variables such as the presence of butts, ashtrays, and smokers. In the posttest assessment, we also recorded the number of outdoor smokers close to the entrance. A total of 351 nicotine and 160 PM2.5 measurements were taken. Both nicotine and PM2.5 concentrations decreased by more than 90% (nicotine from 5.73 to 0.57 µg/m(3), PM2.5 from 233.38 to 18.82 µg/m(3)). After the law came into force, both nicotine and PM2.5 concentrations were significantly higher in venues with outdoor smokers close to the entrance than in those without outdoor smokers. All the observational tobacco consumption variables significantly decreased (p < .001). SHS exposure in hospitality venues dramatically decreased after the 2011 Spanish smoking ban. SHS from outdoor smokers close to entrances seems to drift inside venues. Smoking control legislation should consider outdoor restrictions to ensure complete protection against SHS.

Populações estelares do bojo galáctico

NASA Astrophysics Data System (ADS)

Escudero, A. V.; Costa, R. D. D.; Maciel, W. J.

2003-08-01

Os estudos mais recentes do bojo galáctico têm enfocado essencialmente as abundâncias químicas de elementos pesados, como o ferro, obtidos a partir das estrelas nas regiões centrais da galáxia. Elementos leves, como hélio, nitrogênio, oxigênio e argônio ainda são pouco estudados nestas regiões, devido à difícil determinação de suas abundâncias a partir de estrelas. Nestas condições as nebulosas planetárias desempenham um importante papel, pois permitem a determinação de abundâncias destes elementos usando técnicas de espectroscopia nebular. Neste trabalho, reportamos a análise das abundâncias químicas de uma nova amostra de nebulosas planetárias do bojo, bem como os resultados preliminares de um código numérico destinado a modelar a evolução química desta região. Usamos como vínculos observacionais os resultados obtidos das nebulosas planetárias, bem como de abundâncias estelares da região do bojo, obtidas da literatura. A partir deste modelo da evolução química e dos vínculos observacionais foi possível fazer um diagnóstico mais preciso das populações que constituem o bojo galáctico. O estudo destas populações que compõem a região central de nossa galáxia é de extrema importância para o maior entendimento da evolução química e dinâmica da galáxia como um todo. Por isto, verificamos a importância dos modelos de formação simples e mista utilizados para explicar características da população da região central da galáxia. Algumas destas características são: uma grande dispersão nos valores das abundâncias químicas e um grande espalhamento nas correlações entre as abundâcias de nitrogênio e oxigênio. Estas peculiaridades são dificilmente reproduzidas por modelos de formação simples, e portanto são importantes indícios da validade dos modelos de formação mista, tais como um rápido colapso do bojo seguido de uma evolução secular.

Bulb turbine operating at medium head: XIA JIANG case study

With lots of references for 4-blade bulb turbines, such as these of Wu Jin Xia (4 units - 36.1 MW per unit - 9.2 m rated head), Chang Zhou (15 units - 46.7 MW per unit - 9.5 m rated head) and Tong Wan (4 units - 46.2 MW per unit - 11 m rated head), ALSTOM Power Hydro is one of the major suppliers of bulb turbines operating under medium head for the Chinese market. ALSTOM Power Hydro has been awarded in November 2010 a contract by Jiang Xi Province Xia Jiang Water Control Project Headquarters to equip Xia Jiang's new hydropower plant. The power dam is located on the Gan Jiang river, at about 160 km away from Nan Chang town in South Eastern China. The supply will consist in 5 bulb units including the furniture of both the turbine and its generator, for a total capacity of 200 MW, under a rated net head of 8.6 m. The prototype turbine is a 7.8 m diameter runner, rotating at 71.4 rpm speed. For this project, ALSTOM has proposed a fully new design of 4-blade bulb runner. This paper outlines the main steps of the hydraulic development. First of all, a fine tuning of the blade geometry was performed to enhance the runner behaviour at high loads and low heads, so that to fulfill the demanding requirements of efficiencies and maximum output. The challenge was also to keep an excellent cavitation behaviour, especially at the outer blade diameter in order to avoid cavitation erosion on the prototype. The shape of the blade was optimized by using the latest tools in computational fluid dynamics. Steady state simulations of the distributor and the runner were performed, in order to simulate more accurately the pressure fields on the blade and the velocity distribution at the outlet of the runner. Moreover, draft tube computations have been performed close to the design point and at higher loads. Then, a model fully homologous with the prototype was manufactured and tested at ALSTOM's laboratory in Grenoble (France). The model test results confirmed the predicted ones: the expected weighted average efficiency is higher than the guaranteed value and the maximum output was reached with a comfortable safety margin. A comparison of the experimental and numerical velocity probings under the runner is also proposed as an insight into the prediction of flow behaviour at the inlet of the draft tube.

Abstract Objective To analyse national data on asbestos use and related diseases in the European Region of the World Health Organization (WHO). Methods For each of the 53 countries, per capita asbestos use (kg/capita/year) and age-adjusted mortality rates (deaths/million persons/year) due to mesothelioma and asbestosis were calculated using the databases of the United States Geological Survey and WHO, respectively. Countries were further categorized by ban status: early-ban (ban adopted by 2000, n = 17), late-ban (ban adopted 2001–2013, n = 17), and no-ban (n = 19). Findings Between 1920–2012, the highest per capita asbestos use was found in the no-ban group. After 2000, early-ban and late-ban groups reduced their asbestos use levels to less than or equal to 0.1 kg/capita/year, respectively, while the no-ban group maintained a very high use at 2.2 kg/capita/year. Between 1994 and 2010, the European Region registered 106 180 deaths from mesothelioma and asbestosis, accounting for 60% of such deaths worldwide. In the early-ban and late-ban groups, 16/17 and 15/17 countries, respectively, reported mesothelioma data to WHO, while only 6/19 countries in the no-ban group reported such data. The age-adjusted mortality rates for mesothelioma for the early-ban, late-ban and no-ban groups were 9.4, 3.7 and 3.2 deaths/million persons/year, respectively. Asbestosis rates for the groups were 0.8, 0.9 and 1.5 deaths/million persons/year, respectively. Conclusion Within the European Region, the early-ban countries reported most of the current asbestos-related deaths. However, this might shift to the no-ban countries, since the disease burden will likely increase in these countries due the heavy use of asbestos. PMID:25378740

Home and car smoking bans implemented by caregivers are important approaches to reducing children's secondhand smoke (SHS) exposure and attendant health risks. Such private smoking bans are usually informal and are subject to individuals' interpretation, observation, and recall. Relying on a single reporter may lead to misclassification of bans in families. To determine (1) proportion of families with discordant reports of bans; (2) association between parent-child report agreement and SHS exposure; and (3) whether including a second reporter of bans improves prediction of child SHS exposure. In each of 386 participating families a preteen and a parent reported separately on their home and car smoking bans, and agreement was determined. ANOVA, chi-square, and multiple linear regression were used to determine relationships between SHS exposure (measured by urine cotinine and reported exposure) and home/car smoking bans reported by preteens and parents. In 19% of families, reports disagreed for home smoking bans; 30%, for car smoking bans. Families who agreed on the presence of a ban had the lowest exposure, families who agreed on the absence of a ban had the highest exposure, and intermediate exposure for those who disagreed. Parent and child reports of bans each explained significant, unique variance in child SHS exposure. Due to relatively high prevalence of discordant reporting, a more accurate classification of home/car smoking bans may result from including multiple reporters.

Xia Futou, a small Chinese village with a unique cultural landscape, consists of two unbalanced parts, an old village up the hill and a new one down the hill. In order to upgrade and preserve the unique cultural landscape of the older village and rebalance the dislocation of the two parts, a small public bathhouse project has been carried out according to sustainable architecture principles. Based on the current cultural landscape of the bathhouse and its surroundings, this approach is attempting to localize an informed, balance-seeking, design process in the village and in so doing develop a series of diverse possibilities and beneficial paths. The experiment of the public bathhouse's design and construction led to two key conceptual questions that need to be examined, the one is to research a village with a dynamic system conception instead of a static one; the other is to research a village with a self-organizing system conception1 instead of an organized one. Furthermore, we can give the sustainable path for the future that such naturally evolved Chinese villages evolve into sustainable towns and cities.

Smoking bans and the secondhand smoking problem: an economic analysis.

PubMed

Hofmann, Annette; Nell, Martin

2012-06-01

Smoking bans are gaining widespread support in the European Union and other countries. The vast majority of these bans are partial bans given that smoking is still permitted in certain places. This article investigates the role of partial smoking bans in coping with externalities caused by the secondhand smoking problem. Although it is widely known that Pigouvian taxation is superior to a perfect ban, this result does not necessarily carry over to a partial ban because taxes cannot (easily) be differentiated according to location. We show that under an easy and intuitive condition, (1) enacting a partial smoking ban alone always improves social welfare (a) in an unregulated society and (b) even in a regulated society if externalities can be eliminated, and (2) it is ensured that a combination of Pigouvian tax and a partial smoking ban leads to a higher social optimum than implementing corrective Pigouvian taxation alone.

Driver Cellphone and Texting Bans in the United States: Evidence of Effectiveness

PubMed Central

McCartt, Anne T.; Kidd, David G.; Teoh, Eric R.

2014-01-01

Almost all U.S. states have laws limiting drivers’ cellphone use. The evidence suggests that all-driver bans on hand-held phone conversations have resulted in long-term reductions in hand-held phone use, and drivers in ban states reported higher rates of hands-free phone use and lower overall phone use compared with drivers in non-ban states. Bans on all phone use by teenage drivers have not been shown to reduce their phone use. The effects of texting bans on the rates of drivers’ texting are unknown. With regard to the effects of bans on crashes, 11 peer-reviewed papers or technical reports of all-driver hand-held phone bans and texting bans were reviewed. Some were single-state studies examining crash measures before and after a state ban; other national or multi-state studies compared crashes in states with and without bans over time. The results varied widely. The lack of appropriate controls and other challenges in conducting strong evaluations limited the findings of some studies. Thus, despite the proliferation of laws limiting drivers’ cellphone use, it is unclear whether they are having the desired effects on safety. Priorities for future research are suggested.

Workplace smoking ban policy and smoking behavior.

PubMed

Kim, Beomsoo

2009-09-01

To evaluate the impact of the workplace smoking ban in South Korea, where the male smoking rate is high (57%), on smoking behavior and secondhand smoke exposure. A workplace smoking ban legislation implemented in April 2003 requires offices, meeting rooms, and lobbies located in larger than 3,000 square meter buildings (or 2,000 square meter multipurpose buildings) should be smoke free. A representative cross-sectional survey, the third wave (2005) of health supplements in the National Health Nutrition Survey of South Korea, was used to measure the impact of the 2003 workplace smoking ban implementation on smoking behavior. It contained 3,122 observations of adults 20 to 65 years old (excluding self-employed and non-working populations). A multivariate statistical model was used. The self-reported workplace smoking ban policy (full workplace ban, partial workplace ban, and no workplace ban) was used as the key measure. A full workplace smoking ban reduced the current smoking rate by 6.4 percentage points among all workers and also decreased the average daily consumption among smokers by 3.7 cigarettes relative to no smoking ban. Secondhand smoke showed a dramatic decrease of 86 percent (= -1.74/2.03)from the sample mean for full workplace ban. However, public anti-smoking campaign did not show any significant impact on smoking behavior. The full workplace ban policy is effective in South Korea. Male group showed bigger impact of smoking ban policy than female group. The public antismoking campaign did not show any effectiveness.

To examine youth exposure to smoking in cars following 7 provincial bans on smoking in cars with children in Canada. Repeated cross-sectional data from the 2004-2012 Youth Smoking Survey (n=91,800) were examined. Using a quasi-experimental design, contrasts of the interaction of survey year and province included in the logistic regression analyses were used to test whether exposure significantly declined pre-post implementation of a ban on smoking in cars relative to control provinces not implementing a ban. Exposure across all provinces declined from 26.5% in 2004 to 18.2% of youth in 2012. Exposure declined significantly from pre to post implementation of a ban on smoking in cars with children in Ontario at time 1 post ban (Pre-Ban=20.4% T1post=10.3%, OR=0.45), time 2 post ban (12.1%, OR=0.61) and time 3 post ban (11.6%, OR=0.58) relative to control provinces that did not implement a ban. In British Columbia exposure to smoking in cars declined significantly at pre-post ban time 3 compared to the control group (Pre-Ban=21.2%, T3post=9.6%, OR=0.51). No other provinces had a significant change in exposure pre-post ban relative to the control provinces. Although rates declined, significant differences were only found in Ontario relative to control provinces in the immediate and long term. Copyright © 2015 Elsevier Inc. All rights reserved.

Fireworks related injuries during Hari Raya festival in Hospital Universiti Sains Malaysia--1986 to 1990.

Isa, A R; Moe, H

1991-12-01

A total of 38 cases of fireworks related injuries from Hospital USM over a 5-year period from 1986 to 1990 during Hari Raya festival were analysed. The majority (68.5%) of the patients were teenagers, between 10 to 19 years of age. All the cases were Malays and most of the accidents occurred before the Hari Raya Idilfitri festive seasons. Fourteen cases were caused by self-made fireworks and another 16 cases were due to modified fire-works. Twenty-four cases suffered permanent disabilities mostly finger amputations. Such injuries could be prevented by law enforcement coupled with public health education to modify social behaviour especially when the ban against the use of fireworks is lifted on religious grounds.

Estudos recentes da cinemática da região dentro de 1 kpc do núcleo de galaxias Seyfert próximas usando espectroscopia de fenda longa com alta resolução espacial (~ 100 pc ou melhores) encontraram uma queda na dispersão de velocidades nas regiões centrais dentro de um raio de ~ 300 pc do núcleo. Essa queda vem sendo tentativamente explicada por um cenário evolutivo em que um evento de formação estelar recente cria as estrelas da região central em um disco de dimensões 300 pc. Desde sua criação, tais estrelas não tiveram tempo de "virializar", ou seja, seguir a distribuição radial de dispersões de velocidades determinada pelo campo gavitacional da galáxia e, portanto, a dispersão de velocidades medida nessa região do bojo acaba sendo menor do que a dispersão medida nas vizinhanças. No presente trabalho investigamos a cinemática estelar no núcleo das galáxias Seyfert NGC 4051 e NGC 4941 usando o tripleto do Ca ii (8500 Å) em absorção. Os dados foram obtidos com o IFU GMOS no telescópio Gemini. O elemento de resolução espacial nas galáxias é da ordem de 30 pc. No intervalo espectral coberto pelo espectrografo a linha [S iii] (9068 Å) também é visível, o que permite estudar a cinemática do gás na mesma região. Serão apresentados mapas bi-dimensionais da velocidade e dispersão de velocidades das estrelas e do gás, além de imagens na linha [S iii] que mapeia o gás de alta excitação.

Productive Recognition of Factor IX by Factor XIa Exosites Requires Disulfide Linkage between Heavy and Light Chains of Factor XIa*

PubMed Central

Marcinkiewicz, Mariola M.; Sinha, Dipali; Walsh, Peter N.

2012-01-01

In the intrinsic pathway of blood coagulation factor XIa (FXIa) activates factor IX (FIX) by cleaving the zymogen at Arg145-Ala146 and Arg180-Val181 bonds releasing an 11-kDa activation peptide. FXIa and its isolated light chain (FXIa-LC) cleave S-2366 at comparable rates, but FXIa-LC is a very poor activator of FIX, possibly because FIX undergoes allosteric modification on binding to an exosite on the heavy chain of FXIa (FXIa-HC) required for optimal cleavage rates of the two scissile bonds of FIX. However preincubation of FIX with a saturating concentration of isolated FXIa-HC did not result in any potentiation in the rate of FIX cleavage by FXIa-LC. Furthermore, if FIX binding via the heavy chain exosite of FXIa determines the affinity of the enzyme-substrate interaction, then the isolated FXIa-HC should inhibit the rate of FIX activation by depleting the substrate. However, whereas FXIa/S557A inhibited FIX activation of by FXIa, FXIa-HC did not. Therefore, we examined FIX binding to FXIa/S557A, FXIa-HC, FXIa-LC, FXIa/C362S/C482S, and FXIa/S557A/C362S/C482S. The heavy and light chains are disulfide-linked in FXIa/S557A but not in FXIa/C362S/C482S and FXIa/S557A/C362S/C482S. In an ELISA assay only FXI/S557A ligated FIX with high affinity. Partial reduction of FXIa/S557A to produce heavy and light chains resulted in decreased FIX binding, and this function was regained upon reformation of the disulfide linkage between the heavy and the light chains. We therefore conclude that substrate recognition by the FXIa exosite(s) requires disulfide-linked heavy and light chains. PMID:22207756

The population impact of smoke-free workplace and hospitality industry legislation on smoking behaviour. Findings from a national population survey.

To study the impact of implementing smoke-free workplace and hospitality industry legislation on smoking behaviour. A cross-sectional population survey from 2001 to 2008 (n ≈ 18,000 per year) was used to assess trends and seasonal patterns in smoking and quitting, and to examine whether changes could be observed after the workplace smoking ban in the Netherlands in 2004 and the hospitality industry ban in 2008. Outcome measures were smoking prevalence, quit attempts and successful quit attempts. Interactions with educational level (socio-economic status) and bar visiting (exposure to the hospitality industry ban) were tested. The workplace ban was followed by a decrease in smoking prevalence (OR = 0.91, P < 0.001), but the hospitality industry ban was not (OR = 0.96, P = 0.127). Both bans, especially the workplace ban, were followed by an increase in quit attempts and successful quit attempts: workplace ban, OR = 1.31, P < 0.001; OR = 1.49, P < 0.001; hospitality industry ban, OR = 1.13, P = 0.013; OR = 1.44, P < 0.001. The workplace ban had a larger effect on successful quitting among higher-educated (OR = 0.35, P < 0.001) than on lower-educated respondents (OR = 0.74, P = 0.052). The hospitality industry ban had a larger effect on quit attempts among frequent bar visitors (OR = 1.48, P = 0.003) than on non-bar visitors (OR = 0.71, P = 0.014). A workplace smoking ban in the Netherlands was followed by more changes in smoking and quitting than a hospitality industry ban. The hospitality industry ban only appeared to have an impact on quit attempts, and not on smoking prevalence. © 2010 The Authors, Addiction © 2010 Society for the Study of Addiction.

Alcohol advertising bans and alcohol abuse: an international perspective.

Advertising bans as a means of tobacco control policy: a systematic literature review of time-series analyses.

PubMed

Quentin, Wilm; Neubauer, Simone; Leidl, Reiner; König, Hans-Helmut

2007-01-01

This paper reviews the international literature that employed time-series analysis to evaluate the effects of advertising bans on aggregate consumption of cigarettes or tobacco. A systematic search of the literature was conducted. Three groups of studies representing analyses of advertising bans in the U.S.A., in other countries and in 22 OECD countries were defined. The estimated effects of advertising bans and their significance were analysed. 24 studies were identified. They used a wide array of explanatory variables, models, estimating methods and data sources. 18 studies found a negative effect of an advertising ban on aggregate consumption, but only ten of these studies found a significant effect. Two studies using data from 22 OECD countries suggested that partial bans would have little or no influence on aggregate consumption, whereas complete bans would significantly reduce consumption. The results imply that advertising bans have a negative but sometimes only narrow impact on consumption. Complete bans let expect a higher effectiveness. Because of methodological restrictions of analysing advertising bans' effects by time series approaches, also different approaches should be used in the future.

Few longitudinal studies have examined the adoption of bans on smoking in private homes. This longitudinal study examined: (1) the prevalence of home smoking bans at baseline, (2) the incidence and predictors of new ban implementation by follow-up, and (3) the reasons for banning smoking and the difficulties with enforcement. The sample consisted of 1360 adults of Korean descent residing in California who were interviewed by telephone (in English/Korean) at baseline during 2001-2002 and re-interviewed in 2006-2007. Data analyses were conducted in 2007-2008. The proportion of respondents with a complete household smoking ban grew from 59% at baseline to 91% by the follow-up interview. Among the 552 respondents who did not have a ban at baseline, 84% had adopted a ban by follow-up. Three baseline factors independently predicted ban adoption during the follow-up period: the presence of a nonsmoking respondent or spouse, the presence of nonsmoking family members, and respondent's belief that secondhand smoke caused lung cancer. The most highly rated reasons for banning smoking were as follows: because smoke annoys others, to protect family members, to avoid the odor, to discourage youth from smoking, and to encourage smokers to quit. Finally, respondents indicated that they would find it most difficult to ask their parent-in-law not to smoke. The proportion of households with smoking bans increased substantially, but households with smokers or family members who smoke remained less likely to implement bans. The importance of culturally sensitive programs to promote household bans cannot be overstated.

Understanding who establishes partial home smoking bans, what these bans cover, and whether they are an intermediate step in going smoke-free would help to inform smoke-free home interventions. Participants were recruited from United Way of Greater Atlanta’s 2-1-1 contact center. Data were collected at baseline, 3 and 6 months via telephone interview. Participants (n = 375) were mostly African American (84.2%) and female (84.3%). The majority (58.5%) had annual household incomes <$10 000. At baseline, 61.3% reported a partial smoking ban and 38.7% reported no ban. Existence of a partial ban as compared with no ban was associated with being female, having more than a high school education, being married and younger age. Partial bans most often meant smoking was allowed only in designated rooms (52.6%). Other common rules included: no smoking in the presence of children (18.4%) and smoking allowed only in combination with actions such as opening a window or running a fan (9.8%). A higher percentage of households with partial bans at baseline were smoke-free at 6 months (36.5%) compared with households with no bans at baseline (22.1%). Households with partial smoking bans may have a higher level of readiness to go smoke-free than households with no restrictions. PMID:26661723

Effect of air pollution control on mortality and hospital admissions in Ireland.

2013-07-01

During the 1980s the Republic of Ireland experienced repeated severe pollution episodes. Domestic coal burning was a major source of this pollution. In 1990 the Irish government introduced a ban on the marketing, sale, and distribution of coal in Dublin. The ban was extended to Cork in 1995 and to 10 other communities in 1998 and 2000. We previously reported decreases in particulate black smoke (BS*) and sulfur dioxide (SO2) concentrations, measured as total gaseous acidity, in Dublin after the 1990 coal ban (Clancy et al. 2002). In the current study we explored and compared the effectiveness of the sequential 1990, 1995, and 1998 bans in reducing community air pollution and in improving public health. We compiled records of daily BS, total gaseous acidity (SO2), and counts of cause-specific deaths from 1981 to 2004 for Dublin County Borough (1990 ban), county Cork (1995 ban), and counties Limerick, Louth, Wexford, and Wicklow (1998 ban). We also compiled daily counts of hospital admissions for cardiovascular, respiratory, and digestive diagnoses for Cork County Borough (1991 to 2004) and counties Limerick, Louth, Wexford, and Wicklow (1993 to 2004). We compared pre-ban and post-ban BS and SO2 concentrations for each city. Using interrupted time-series methods, we estimated the change in cause-specific, directly standardized mortality rates in each city or county after the corresponding local coal ban. We regressed weekly age- and sex-standardized mortality rates against an indicator of the post- versus pre-ban period, adjusting for influenza epidemics, weekly mean temperature, and a season smooth of the standardized mortality rates in Coastal counties presumably not affected by the bans. We compared these results with similar analyses in Midlands counties also presumably unaffected by the bans. We also estimated the change in cause-specific, directly standardized, weekly hospital admissions rates normalized for underreporting in each city or county after the 1995 and 1998 bans, adjusting for influenza epidemics, weekly mean temperature, and local admissions for digestive diagnoses. Mean BS concentrations fell in all affected population centers post-ban compared with the pre-ban period, with decreases ranging from 4 to 35 microg/m3 (corresponding to reductions of 45% to 70%, respectively), but we observed no clear pattern in SO2 measured as total gaseous acidity associated with the bans. In comparisons with the pre-ban periods, no significant reduction was found in total death rates associated with the 1990 (1% reduction), 1995 (4% reduction), or 1998 (0% reduction) bans, nor for cardiovascular mortality (0%, 4%, and 1% reductions for the 1990, 1995, and 1998 bans, respectively). Respiratory mortality was reduced in association with the bans (17%, 9%, and 3%, respectively). We found a 4% decrease in hospital admissions for cardiovascular disease associated with the 1995 ban and a 3% decrease with the 1998 ban. Admissions for respiratory disease were not consistently lower after the bans; admissions for pneumonia, chronic obstructive pulmonary disease (COPD), and asthma were reduced. However, underreporting of hospital admissions data and lack of control and comparison series tempered our confidence in these results. The successive coal bans resulted in immediate and sustained decreases in particulate concentrations in each city or town; with the largest decreases in winter and during the heating season. The bans were associated with reductions in respiratory mortality but no detectable improvement in cardiovascular mortality. The changes in hospital admissions for respiratory and cardiovascular disease were supportive of these findings but cannot be considered confirming. Detecting changes in public health indicators associated even with clear improvements in air quality, as in this case, remains difficult when there are simultaneous secular improvements in the same health indicators.

Hospital Admissions for Acute Myocardial Infarction, Angina, Stroke, and Asthma After Implementation of Arizona's Comprehensive Statewide Smoking Ban

PubMed Central

Walsh, Michele E.

2011-01-01

Objectives. We examined the impact of Arizona's May 2007 comprehensive statewide smoking ban on hospital admissions for diagnoses for which there is evidence of a causal relationship with secondhand smoke (SHS) exposure (acute myocardial infarction [AMI], angina, stroke, and asthma). Methods. We compared monthly hospital admissions from January 2004 through May 2008 for these primary diagnoses and 4 diagnoses not associated with SHS (appendicitis, kidney stones, acute cholecystitis, and ulcers) for Arizona counties with preexisting county or municipal smoking bans and counties with no previous bans. We attributed reductions in admissions to the statewide ban if they occurred only in diagnoses associated with SHS and if they were larger in counties with no previous bans. We analyzed the data with Poisson regressions, controlling for seasonality and admissions trends. We also estimated cost savings. Results. Statistically significant reductions in hospital admissions were seen for AMI, angina, stroke, and asthma in counties with no previous bans over what was seen in counties with previous bans. No ban variable coefficients were statistically significant for diagnoses not associated with SHS. Conclusions. Arizona's statewide smoking ban decreased hospital admissions for AMI, stroke, asthma, and angina. PMID:20466955

Patron Banning in the Nightlife Entertainment Districts: A Key Informant Perspective.

Miller, Peter; Curtis, Ashlee; Palmer, Darren; Warren, Ian; McFarlane, Emma

2016-07-01

Alcohol-related harm in and around licensed venues is associated with substantial costs. Many interventions have been introduced in an effort to combat these harms, and one such intervention is known as patron banning. Patron banning involves prohibiting patrons who have been violent or disorderly in a licensed venue in an attempt to reduce alcohol-related harm. It can be implemented by the venue, by members of police, or by liquor accords. This study aimed to obtain key informant perspectives on the benefits of patron banning as well as on the effectiveness of patron banning in reducing alcohol-related harm. Thirty-six key informants provided perspectives on patron banning through in-depth interviews that were part of a larger study. Key informants were supportive of patron banning for reducing alcohol-related harm, noting that it had many benefits including increased venue safety, general risk management, and deterrence of antisocial behavior. Although processes for banning were not always consistent, identification scanners were generally recognized as a way to ensure that patron banning was enforced. Key informants viewed patron banning as an effective measure for increasing patron safety and reducing alcohol-related harms.

Secondhand smoke exposure in children is changing as a result of new public policy and electronic nicotine products (e-cigarettes). We examined factors related to self-imposed indoor household tobacco restrictions, with emphasis on children in the household and associations with combustible and noncombustible product use. A cross-sectional survey of urban and rural Ohio adult tobacco users classified participants as exclusive combustible users, smokeless tobacco (SLT) users, e-cigarette users, or dual users. They were further stratified according to combustible or noncombustible product use and the presence of indoor tobacco use restrictions. Multiple logistic regression determined factors associated with indoor tobacco restrictions. A total of 1210 tobacco users participated, including 25.7% with children living in the home. Half allowed combustible and two thirds allowed noncombustible tobacco use indoors. Urban location (odds ratio [OR] = 1.58), younger age (OR = 0.88 per 5 year), male sex (OR = 1.40), college education (OR = 1.40), household income of more than $15,000 (OR = 1.78), and being married (OR = 2.43) were associated with a higher likelihood of banning combustible products indoors. SLT (OR = 8.12) and e-cigarette (OR = 5.85) users were more likely to have indoor bans compared to combustible users. Children in the household (OR = 1.89), older age (OR = 1.12 per 5 years), and nonwhite race (OR = 1.68) were associated with a higher likelihood of banning noncombustible products indoors. Combustible (OR = 4.54) and e-cigarette (OR = 3.04) users were more likely than SLT users to have indoor bans. Indoor restrictions on tobacco use remain infrequent in homes with children and are associated with user type and socioeconomic factors. Public policy should target modifiable risk factors for in-home secondhand smoke exposure. Copyright © 2018 Academic Pediatric Association. Published by Elsevier Inc. All rights reserved.

Guidelines for asbestos remediation at Italian superfund sites.

Paglietti, F; Malinconico, S; Di Molfetta, V; Giangrasso, M

2012-01-01

Asbestos is now banned in 52 countries. Although Italy banned asbestos in 1992, up until that date it had been one of the main producer nations of asbestos and asbestos-containing materials, and asbestos-related contamination is still widespread in the country. To reduce asbestos-related health effects, Italy has adopted many laws and regulations regarding exposure thresholds and remediation tools. Even so, there are legislative gaps that are making it difficult to manage related risks especially in the operative phase. The lack of standard procedures at a national level regarding emergency shutdown and remediation as well as reference thresholds for specific risk situations creates difficulties and different actions when dealing with the cleanup of Italian asbestos superfund sites. The authors propose operative guidelines for asbestos remediation at Italian superfund sites. INAIL, the reference national organization for asbestos-related matters, acting as an advisor to a number of state, regional, and local authorities, examined the main asbestos-related risk situations in Italy and proposed the most appropriate actions to take. The detailed analysis of many actual cases of risk, in part through inspections and the management of cleanup actions at asbestos Italian superfund sites, resulted in proposals to modify existing procedures and thresholds, which were subsequently discussed with all national, regional, and local scientific bodies. After more than two years of work and discussion at a national level, INAIL-DIPIA-Asbestos Group drafted new Guidelines for Asbestos Remediation at Italian Superfund sites, and officially submitted them to the Environment Ministry. The Ministry then adopted the document in regard to all asbestos Italian superfunds. This recently released document is also a useful reference for contaminated sites at a regional and local level. The operative Guidelines for Asbestos Remediation at Italian Superfund sites may also be of use at an international level for countries that have already banned asbestos and are engaged in remediation activity and for countries that have not yet banned asbestos but wish to adopt risk prevention measures.

The impact of tobacco advertising bans on consumption in developing countries.

Tobacco advertising bans have become commonplace in developed nations but are less prevalent in developing countries. The importance of advertising bans as part of comprehensive tobacco control strategies has been emphasised by the Framework Convention on Tobacco Control which calls for comprehensive bans on tobacco advertising. The empirical literature suggests that comprehensive advertising bans have played a role in reducing consumption in developed countries but that limited policies have not. This paper extends this analysis to include 30 developing countries and finds that bans do play an important role in reducing tobacco consumption in these countries. It finds that both comprehensive as well as limited policies are effective in reducing consumption although comprehensive bans have a far greater impact than limited ones. Furthermore, it finds that advertising bans may be even more effective in the developing world than they are in the developed world.

Communicating contentious health policy: lessons from Ireland's workplace smoking ban.

The Irish workplace smoking ban has been described as possibly a tipping point for public health worldwide. This article presents the first analysis of the newspaper coverage of the ban over the duration of the policy formation process. It adds to previous studies by analyzing how health communication strategists engaged, over time, with a newsworthy topic, viewed as being culturally controversial. It analyzes a sample of media content (n = 1,154) and firsthand accounts from pro-ban campaigners and journalists (n = 10). The analysis shows that the ban was covered not primarily as a health issue: Economic, political, social, democratic, and technical aspects also received significant attention. It shows how coverage followed controversy and examines how pro-ban campaigners countered effectively the anti-ban communication efforts of influential social actors in the economic and political spheres. The analysis demonstrates that medical-political sources successfully defined the ban's issues as centrally concerned with public health.

Assessing the impact of the national smoking ban in indoor public places in china: evidence from quit smoking related online searches.

Despite the tremendous economic and health costs imposed on China by tobacco use, China lacks a proactive and systematic tobacco control surveillance and evaluation system, hampering research progress on tobacco-focused surveillance and evaluation studies. This paper uses online search query analyses to investigate changes in online search behavior among Chinese Internet users in response to the adoption of the national indoor public place smoking ban. Baidu Index and Google Trends were used to examine the volume of search queries containing three key search terms "Smoking Ban(s)," "Quit Smoking," and "Electronic Cigarette(s)," along with the news coverage on the smoking ban, for the period 2009-2011. Our results show that the announcement and adoption of the indoor public place smoking ban in China generated significant increases in news coverage on smoking bans. There was a strong positive correlation between the media coverage of smoking bans and the volume of "Smoking Ban(s)" and "Quit Smoking" related search queries. The volume of search queries related to "Electronic Cigarette(s)" was also correlated with the smoking ban news coverage. To the extent it altered smoking-related online searches, our analyses suggest that the smoking ban had a significant effect, at least in the short run, on Chinese Internet users' smoking-related behaviors. This research introduces a novel analytic tool, which could serve as an alternative tobacco control evaluation and behavior surveillance tool in the absence of timely or comprehensive population surveillance system. This research also highlights the importance of a comprehensive approach to tobacco control in China.

Our aim was to assess second-hand smoke (SHS) exposure in hospitality venues after the smoke-free legislation implemented in September 2010 in Greece and to compare with when a partial ban was in place and in 2006 when no ban was in place. Hospitality venues were prospectively assessed for their indoor concentrations of particulate matter (PM(2.5)) during the partial ban phase (n=149) and the complete ban phase (n=120, 80% followed up), while overall and matched by venue comparisons were also performed (no ban vs. partial ban vs. complete ban). Comparisons with previously collected data in 2006 when no ban was in place also was performed. Indoor air levels of PM(2.5) attributable to SHS dropped following the transition from a partial to a complete ban by 34% (137 μg/m(3) vs. 90 μg/m(3), p=0.003). This drop was larger in bars (from 195 μg/m(3) to 121 μg/m(3)), than in cafes (124 μg/m(3) vs. 87 μg/m(3)) or restaurants (42 μg/m(3) vs. 39 μg/m(3)). PM(2.5) concentrations between 2006 (no ban) and the partial ban of 2010 were also found to decrease by 94 μg/m(3); however, among matched venues, the levels of indoor air pollution were not found to change significantly (218 μg/m(3) vs. 178 μg/m(3), p=0.58). Comparing the 2010 complete ban results (n=120) with previously collected data from 2006 when no ban was in place (n=43), overall PM(2.5) concentrations were found to fall from 268 μg/m(3) to 89 μg/m(3), while a matched analysis found a significant reduction in PM(2.5) concentrations (249 μg/m(3) vs. 46 μg/m(3), p=0.011). The complete ban of smoking in hospitality venues in Greece led to a reduction in SHS exposure, in comparison to when the partial ban or no ban was in place; however, exposure to SHS was not eliminated indicating the need for stronger enforcement.

In September 2005 Thailand became the first Asian country to implement a complete ban on the display of cigarettes and other tobacco products at point-of-sale (POS). This paper examined the impact of the POS tobacco display ban in Thailand, with Malaysia (which did not impose bans) serving as a comparison. The data came from the International Tobacco Control Southeast Asia Survey (2005-2011), a prospective cohort survey designed to evaluate the psychosocial and behavioral impacts of tobacco control policies. Main measures included smokers' reported awareness of tobacco displays and advertising at POS. At the first post-ban survey wave over 90% of smokers in Thailand were aware of the display ban policy and supported it, and about three quarters thought the ban was effective. Noticing tobacco displays in stores was lowest (16.9%) at the first post-ban survey wave, but increased at later survey waves; however, the levels were consistently lower than those in Malaysia. Similarly, exposure to POS tobacco advertising was lower in Thailand. The display ban has reduced exposure to tobacco marketing at POS. The trend toward increased noticing is likely at least in part due to some increase in violations of the display bans and/or strategies to circumvent them.

The causal link between ultraviolet radiation from solarium use and skin cancer is well established. In 2012 and 2013, state governments across Australia announced plans to ban commercial solarium use from 31 December 2014. The present study examined the responses of solarium and non-solarium users to the ban on commercial solariums in Australia. Participants (n = 488; 388 females, 100 males; mean age = 26.02, s.d. = 9.95) completed an online questionnaire during the summer prior to the ban relating to solarium usage and their opinions about the ban. Overall, 49% (n = 237) of participants were aware of the impending ban; 17% (n = 83) had used a solarium at some point in their life. The response to the solarium ban was positive; however, some current solarium users intended post-ban to use privately owned sunbeds and or spend a greater amount of time sun-tanning. These findings indicate a high level of public support for the solarium ban, which has removed a risky source of ultraviolet radiation in Australia. SO WHAT? Further steps are now needed to monitor the tanning behaviours of previous solarium users post-ban and their access to private sunbed use and other potentially dangerous methods of tanning (e.g. tanning injections).

In February 2009, Guatemala implemented a comprehensive smoking ban. We assessed air nicotine levels in bars and restaurants 6 months after the ban (post-ban) and compared them with levels found in 2006 (pre-ban). Exposure was estimated by passive sampling of vapor-phase nicotine using samplers (n=50) placed for 7 working days in 10 bars and 11 restaurants in Guatemala City. Air nicotine was measured by gas chromatography, and the time-weighted average concentration in μg/m(3) was estimated. Employees answered a survey about smoke-free workplaces (n = 32) and compared with pre-ban (n = 37) results. Nicotine was detectable in all bars pre- and post-ban. In restaurants, it was detectable in all pre- and 73% post-ban. Median nicotine concentrations in bars significantly decreased from 4.58 μg/m(3) (IQR, 1.71, 6.45) pre-ban to 0.28 μg/m(3) (IQR 0.17, 0.66) post-ban (87% decrease). In restaurants, concentrations significantly decreased from 0.58 μg/m(3) (IQR, 0.44, 0.71) to 0.04 μg/m(3) (IQR 0.01, 0.11) (95% decrease). Employees' support for a smoke-free workplace increased in the post-ban survey (from 32 to 81%, p < 0.001). Six months after the implementation of a smoke-free law in Guatemala, nicotine levels were significantly decreased in bars and restaurants and workers' support for the law substantially increased.

We used a panel design and the Nationwide Inpatient Sample from 19 states between 2003 and 2010 to examine the impact of texting bans on crash-related hospitalizations. We conducted conditional negative binomial regressions with state, year, and month fixed effects to examine changes in crash-related hospitalizations in states after the enactment of a texting ban relative to those in states without such bans. Results indicate that texting bans were associated with a 7% reduction in crash-related hospitalizations among all age groups. Texting bans were significantly associated with reductions in hospitalizations among those aged 22 to 64 years and those aged 65 years or older. Marginal reductions were seen among adolescents. States that have not passed strict texting bans should consider doing so.

Bans on electronic cigarette sales to minors and smoking among high school students.

PubMed

Abouk, Rahi; Adams, Scott

2017-07-01

Many states have banned electronic cigarette sales to minors under the rationale that using e-cigarettes leads to smoking traditional combustion cigarettes. Such sales bans would be counterproductive, however, if e-cigarettes and traditional cigarettes are substitutes, as bans might push teenagers back to smoking the more dangerous combustion cigarettes. We provide evidence that these sales bans reduce the incidence of smoking conventional cigarettes among high school seniors. Moreover, we provide evidence suggesting that sales bans reduced e-cigarette usage as well. This evidence suggests that not only are e-cigarettes and smoking regular cigarettes positively related and not substitutes for young people, banning retail sales to minors is an effective policy tool in reducing tobacco use.

Tobacco endgame policies are increasingly advocated to end tobacco use. This study investigated public support for a total ban on tobacco sales, use and possession in Hong Kong. A telephone survey was conducted among 1537 randomly selected residents in 2012 to assess their support for a total ban on tobacco sales, usage and possession. Information on sociodemographic characteristics, smoking, and second hand smoke exposure were collected. Logistic regression was used to investigate factors associated with support for a total ban. Most of the never smokers (75.3%), ex-smokers (63.9%), and nearly half of current smokers (48.9%) backed some form of a total ban on tobacco. A total ban on tobacco sales was the most popular option among the three groups, with over half (64.8%) of all respondents supporting a ban within 10 years. Current smoking and higher educational attainment were associated with less support for a total ban on tobacco sales. Among current smokers, having quit intentions and attempts to quit were associated with support for a total ban. A total ban on tobacco sales was supported by most respondents. Ex-smokers and current smokers also voiced substantial support, although less than never smokers. A total ban on tobacco sales before 2022 should be the goal as it is supported by most of the respondents. Interim tobacco control measures, such as tax increases, expansion of smoking cessation services and plain packaging should be implemented to help current smokers quit and reduce smoking initiation before implementation of the ban.

2014-06-01

To reduce obesity and type 2 diabetes rates, lawmakers have proposed modifying Supplemental Nutrition Assistance Program (SNAP) benefits to encourage healthier food choices. We examined the impact of two proposed policies: a ban on using SNAP dollars to buy sugar-sweetened beverages; and a subsidy in which for every SNAP dollar spent on fruit and vegetables, thirty cents is credited back to participants' SNAP benefit cards. We used nationally representative data and models describing obesity, type 2 diabetes, and determinants of food consumption among a sample of over 19,000 SNAP participants. We found that a ban on SNAP purchases of sugar-sweetened beverages would be expected to significantly reduce obesity prevalence and type 2 diabetes incidence, particularly among adults ages 18-65 and some racial and ethnic minorities. The subsidy policy would not be expected to have a significant effect on obesity and type 2 diabetes, given available data. Such a subsidy could, however, more than double the proportion of SNAP participants who meet federal vegetable and fruit consumption guidelines.

To study the effect of a teachers' ban on supervising sports-related extracurricular physical activities (ECAs), levels of physical activity among 979 grade 7 students (mean age=12.7 [0.5] years at baseline) were compared during and after the ban in seven schools that fully implemented the ban, and three schools that did not implement the ban fully. On average, schools offered 18.0 (SD=5.1) ECAs during a no-ban school year. Students attending full implementation schools were significantly more likely than students in nonimplementation schools to be active after the ban ended (odds ratio for being active=1.89 [95% confidence interval: 1.39, 2.58]). They also increased the number of physical activities in which they participated (coefficient=4.04; SE=1.01). Ending a teachers' ban on sports-related ECAs was associated with increased involvement in physical activity among secondary school students.

Improving the limits of detection of low background alpha emission measurements

2018-01-01

Alpha particle emission - even at extremely low levels - is a significant issue in the search for rare events (e.g., double beta decay, dark matter detection). Traditional measurement techniques require long counting times to measure low sample rates in the presence of much larger instrumental backgrounds. To address this, a commercially available instrument developed by XIA uses pulse shape analysis to discriminate alpha emissions produced by the sample from those produced by other surfaces of the instrument itself. Experience with this system has uncovered two residual sources of background: cosmogenics and radon emanation from internal components. An R&D program is underway to enhance the system and extend the pulse shape analysis technique further, so that these residual sources can be identified and rejected as well. In this paper, we review the theory of operation and pulse shape analysis techniques used in XIA's alpha counter, and briefly explore data suggesting the origin of the residual background terms. We will then present our approach to enhance the system's ability to identify and reject these terms. Finally, we will describe a prototype system that incorporates our concepts and demonstrates their feasibility.

Isolation and characterization of agar-digesting Vibrio species from the rotten thallus of Gracilariopsis heteroclada Zhang et Xia.

Gracilariopsis heteroclada Zhang et Xia (Gracilariaceae, Rhodophyta) is one of the most studied marine seaweeds due to its economic importance. This has been cultivated extensively on commercial scale in the Philippines and other Asian countries. However, sustainable production of G. heteroclada in the Philippines could not be maximized due to the occurrence of rotten thallus disease. Thus, isolation and characterization of agar-digesting bacteria from the rotten thalli of G. heteroclada was conducted. A total of seven representative bacterial isolates were randomly selected based on their ability to digest agar as evidenced by the formation of depressions around the bacterial colonies on nutrient agar plates supplemented with 1.5% NaCl and liquefaction of agar. Gram-staining and biochemical characterization revealed that isolates tested were gram-negative rods and taxonomically identified as Vibrio parahaemolyticus (86-99.5%) and Vibrio alginolyticus (94.2-97.7%), respectively. It is yet to be confirmed whether these agar-digesting vibrios are involved in the induction and development of rotten thallus disease in G. heteroclada in concomitance with other opportunistic bacterial pathogens coupled with adverse environmental conditions.

Does the workplace-smoking ban eliminate differences in risk for environmental tobacco smoke exposure at work?

2009-10-01

A workplace-smoking ban in the Netherlands was introduced on January 1, 2004. Before the ban male and low educated employees were at higher risk for exposure to environmental tobacco smoke (ETS). Effective implementation of the ban should result not only in an overall decline of exposure, but also in the disappearance of systematic differences in exposure between subgroups of employees. Data from a Dutch continuous Internet survey were used. From July 2003 through June 2005, 200 respondents were randomly selected each week. The sample consisted of 11,291 non-smoking, working respondents, aged 16-65 years. ETS exposure decreased among all employees and among subgroups at higher risk before the ban. However, also after the ban, males and low educated employees were still most likely to be exposed to ETS. The workplace-smoking ban was effective in reducing ETS exposure among employees. However, after the ban still 52.2% of non-smoking workers reported to be exposed. We did not find the expected stronger effect among employees who were at higher risk. Both before and after implementation of the ban, males and lower educated employees were about two times more likely to be exposed to ETS.

The purpose of this study was to report predictors and prevalence of home and workplace smoking bans in 5 European countries. We conducted a population-based telephone survey of 4977 women, ascertaining factors associated with smoking bans. Odds ratios (ORs) and 95% confidence intervals (CI) were derived using unconditional logistic regression. A complete home smoking ban was reported by 59.5% of French, 63.5% of Irish, 61.3% of Italian, 74.4% of Czech, and 87.0% of Swedish women. Home smoking bans were associated with younger age and being bothered by secondhand smoke, and among smokers, inversely associated with greater tobacco dependence. Among nonsmokers, bans were also related to believing smoking is harmful (OR=1.20, CI: 1.11, 1.30) and having parents who smoke (OR=0.62, CI: 0.52, 0.73). Workplace bans were reported by 92.6% of French, 96.5% of Irish, 77.9% of Italian, 79.1% of Czech, and 88.1% of Swedish women. Workplace smoking bans were reported less often among those in technical positions (OR=0.64, CI: 0.50, 0.82) and among skilled workers (OR=0.53, CI: 0.32, 0.88) than among professional workers. Workplace smoking bans are in place for most workers in these countries. Having a home smoking ban was based on smoking behavior, demographics, beliefs, and personal preference. PMID:19926747

The effectiveness of outdoor smoking bans on smoking behavior among adolescents remains inconclusive. This study evaluates the long-term impact of outdoor school ground smoking bans among adolescents at secondary schools on the use of conventional cigarettes, e-cigarettes (with/without nicotine) and water pipes. Outdoor smoking bans at 19 Dutch secondary schools were evaluated using a quasi-experimental design. Data on 7733 adolescents were obtained at baseline, and at 6 and 18-month follow-up. The impact of outdoor smoking bans on ‘ever use of conventional cigarettes’, ‘smoking onset’, ‘ever use of e-cigarette with nicotine’, ‘e-cigarette without nicotine’, and ‘water pipe’ was measured. Multilevel logistic regression analysis was used. At schools with a ban, implementation fidelity was checked. At schools where a ban was implemented, at 18-month follow-up more adolescents had started smoking compared to the control condition. No effect of implementation of the ban was found for smoking prevalence, e-cigarettes with/without nicotine, and water pipe use. Implementation fidelity was sufficient. No long-term effects were found of an outdoor smoking ban, except for smoking onset. The ban might cause a reversal effect when schools encounter difficulties with its enforcement or when adolescents still see others smoking. Additional research is required with a longer follow-up than 18 months. PMID:29370137

A pseudo cohort study using national cross-sections (2001, 2004, 2007, and 2010) was conducted to examine differences in smoking prevalence under different smoking ban policies such as a complete workplace indoor smoking ban (early or recent implementation) and a partial smoking ban among male public workers and husbands of female nonsmoking public workers. The effectiveness of smoking bans was estimated by difference-in-differences (DID) with age group stratification. The results varied considerably by age and implementation period. Although DID estimates (positive value of DID estimate represents smoking cessation percentage) for both smoking bans on total male smoking were not significant, the over-40 age group indicated a significant DID estimate of 5.0 (95% CI: 0.2, 9.8) for the recent smoking ban. For female workers' husbands' smoking, the over-40 age group indicated positive, but not significant, DID estimates for the early and recent smoking bans of 7.2 (-4.7, 19.2) and 8.4 (-2.0, 18.7), respectively. A complete indoor workplace smoking ban, particularly one recently implemented among public office workers aged over 40, may reduce male workers' smoking and female workers' husbands' smoking compared with a partial smoking ban, but the conclusion remains tentative because of methodological weaknesses in the study.

The impact of outdoor smoking bans on 'ever use of conventional cigarettes', 'smoking onset', 'ever use of e-cigarette with nicotine', 'e-cigarette without nicotine', and 'water pipe' was measured. Multilevel logistic regression analysis was used. At schools with a ban, implementation fidelity was checked. At schools where a ban was implemented, at 18-month follow-up more adolescents had started smoking compared to the control condition. No effect of implementation of the ban was found for smoking prevalence, e-cigarettes with/without nicotine, and water pipe use. Implementation fidelity was sufficient. No long-term effects were found of an outdoor smoking ban, except for smoking onset. The ban might cause a reversal effect when schools encounter difficulties with its enforcement or when adolescents still see others smoking. Additional research is required with a longer follow-up than 18 months.

In the USA, little is known about local variation in retail cigarette prices; price variation explained by taxes, bans, and area-level socio-demographics, and whether taxes and hospitality bans have synergistic effects on smoking prevalence. Cigarette prices 2001–2011 from chain supermarkets and drug stores (n = 2973) were linked to state taxes (n = 41), state and county bar/restaurant smoking bans, and census block group socio-demographics. Hierarchical models explored effects of taxes and bans on retail cigarette prices as well as county smoking prevalence (daily, non-daily). There was wide variation in store-level cigarette prices in part due to differences in state excise taxes. Excise taxes were only partially passed onto consumers (after adjustment, $1 tax associated with $0.90 increase in price, p < 0.0001) and the pass-through was slightly higher in areas that had bans but did not differ by area-level socio-demographics. Bans were associated with a slight increase in cigarette price (after adjustment, $0.09 per-pack, p < 0.0001). Taxes and bans were associated with reduction in smoking prevalence and taxes had a stronger association when combined with bans, suggesting a synergistic effect. Given wide variation in store-level prices, and uneven state/county implementation of taxes and bans, more federal policies should be considered. PMID:28335533

The majority of research on reactions to smoking bans in psychiatric facilities focuses on staff feedback in acute inpatient settings. The purpose of this pilot study was to assess inpatient attitudes about a complete smoking ban in an intermediate to long-term psychiatric facility. One hundred inpatients were surveyed via questionnaire. Inpatients reported changes in smoking and improvements in health as a result of the ban, despite evidence of non-compliant smoking at the facility. There was evidence that inpatients perceived others' attitudes about the ban to be worse than reality. The findings from this pilot study suggest that consequences of smoking bans in psychiatric facilities are not as negative as some perceive. Smoking bans in intermediate to long-term settings may result in improvements in health among both smoking and non-smoking patients.

Background Home smoking bans significantly reduce the likelihood of secondhand smoke exposure among children and non-smoking adults. The purpose of this study was to examine national trends in a) the adoption of home smoking bans; b) discrepancies in parental smoking ban reports; and c) household and parental correlates of home smoking bans among households with underage children from 1995 to 2007. Methods We used data from the 1995/1996, 1998/1999, 2001/2002, 2003 and 2006/2007 Tobacco Use Supplement of the U.S. Current Population Survey to estimate prevalence rates and logistic regression models of parental smoking ban reports by survey period. Results Overall, the prevalence of a complete home smoking bans increased from 58.1% to 83.8% (p<0.01), while discrepancies in parental reports decreased from 12.5% to 4.6% (p<0.01) from 1995 to 2007. Households with single parent, low income, one or two current smokers, parents with less than a college education, or without infants were consistently less likely to report a home smoking ban over this period (p<0.05). Conclusion Despite general improvements in the adoption of home smoking bans and a reduction on parental discrepancies, disparities in the level of protection from secondhand smoke have persisted over time. Children living in households with single parents, low income, current smoker parents, less educated parents, or without infants are less likely to be protected by a home smoking ban. These groups are in need of interventions promoting the adoption of home smoking bans to reduce disparities in tobacco-related diseases. PMID:21813487

Constipation is a common gastrointestinal problem worldwide. The aim of this study was to determine the frequency of use and prescriptive patterns of Chinese herbal medicine (CHM) in treating constipation by analyzing the claims data of traditional Chinese medicine (TCM) from the National Health Insurance (NHI) in Taiwan. The computerized claims dataset of the TCM office visits and the corresponding prescription files in 2004 compiled by the NHI Research Institute in Taiwan were linked and processed. Visit files with the single diagnostic coding of constipation (ICD-9-CM code 564.0) were extracted to analyze the frequency and pattern of corresponding CHM prescriptions. The association rule was applied to analyze the co-prescription of CHM in treating constipation. There were 152,564 subjects who visited TCM clinics only for constipation in Taiwan during 2004 and received a total of 387,268 CHM prescriptions. Subjects between 20 and 29 years of age comprised the largest number of those treated (25.5%). Female subjects used CHM for constipation more frequently than male subjects (female:male = 3.31:1). There was an average of 4.6 items of single Chinese herbs or formula in a single prescription for constipation. Ma-zi-renwan was the most commonly prescribed herbal formula, while Da-huang (Rheum palmatum) was the most commonly used single Chinese herb. According to the association rule, the most common prescribed pattern of 2-drug combination of CHM for treating constipation was Ban-xia-xie-xin-tang plus Ma-zi-ren-wan, while the 3-drug combination of CHM was Fang-feng-tong-sheng-san, Rheum palmatum and Ma-zi-ren-wan. This study showed the pattern of single Chinese herbs or herbal formulae used in treating constipation in Taiwan. Further clinical trials are needed to evaluate the efficacy and safety of these CHMs in treating constipation. 2010 Elsevier. Published by Elsevier B.V. All rights reserved.

Baker, Philip J; Harris, Stephen; Webbon, Charlotte C

2002-09-05

Pressure to ban the hunting of foxes with hounds in Britain has fuelled debate about its contribution to the control of fox populations. We took advantage of a nationwide one-year ban on fox-hunting during the outbreak of foot-and-mouth disease (FMD) in 2001 to examine this issue and found that the ban had no measurable impact on fox numbers in randomly selected areas. Our results argue against suggestions that fox populations would increase markedly in the event of a permanent ban on hunting.

This study investigates differences in terms of clinical and treatment management in psychiatric hospitalization associated to smoking ban. We collected data regarding medication, socio-demographic and admission characteristics from all patients admitted to an acute psychiatric hospital before and after a smoking ban was in force. We also assessed a limited sample of patients before and after the ban regarding nicotine dependence, motivation to quit smoking and attitudes towards the ban. More number of leaves of absence and movement restrictions during the ban period occurred in comparison to the pre-ban period. On the contrary a lack of significant differences in terms of hospital stay (duration, rate of voluntary admissions and voluntary discharges), use of sedatives and doses of antipsychotics was found. A period of adjustment regarding the deal with leave of access and facilitate nicotine replacement treatment may help future psychiatric facilities planning smoking free policies.

In defiance of nuclear deterrence: anti-nuclear New Zealand after two decades.

PubMed

Reitzig, Andreas

2006-01-01

In 1984, nuclear-armed and nuclear-powered vessels were banned from New Zealand to express the country's rejection of the nuclear deterrence concept. This led to a disagreement with the United States. Today, the ban on nuclear-powered ships is the only element of the nuclear-free legislation that still strains US-New Zealand relations. This article presents the reasons for the ban on nuclear-powered ships, which include scientific safety concerns, a symbolic rejection of the nuclear deterrence posture, and patriotic factors such as a nuclear-free national identity. The military and economic consequences of the ban are also examined. Since the ban on nuclear-powered vessels appears to be neither widely known abroad nor commonly recognised as a supportive disarmament measure outside New Zealand, it is concluded that whatever the future of this ban will be, New Zealand's anti-nuclear image will remain known internationally through the ban on nuclear arms.

Purpose . We assessed factors associated with tobacco vendor compliance with India's Cigarettes and Other Tobacco Products Act (COTPA) provisions regulating tobacco sales and point-of-sale (POS) environments. Design . Study design was a cross-sectional random sample of tobacco vendors in Mumbai, India (2010). Setting . School-adjacent neighborhoods were the study setting. Subjects . Study subjects were tobacco vendors (n = 436). Measures . Face-to-face interviews, and audits of POS environments were used to assess compliance. Analysis . Factors associated with compliance were identified using logistic regression. Results . About 4% of vendors were fully compliant. Although 80% reported compliance with the ban on tobacco sales to minors, only 10% displayed signage about the ban. About 84% were compliant with the two-tobacco advertisement limit; of those displaying advertisements, 67% were compliant with size limits, 68% with content restrictions, and 8% with health warning requirements. Knowledge about fines for noncompliance was associated with compliance with the ban on sales to minors (odds ratio [OR], 2.12; 95% confidence interval [CI], 1.26, 3.56) and signage requirement (OR, 4.42; 95% CI, 1.76, 11.13). Greater compliance with the two-advertisement limit was associated with higher store income from tobacco (OR, .26; 95% CI, .09, .73) and lower neighborhood socioeconomic status (p < .01); the latter was associated with advertisement size limits compliance (p < .05). Conclusions . Compliance with COTPA provisions was low. Interventions modifying vendor knowledge about provisions and fines may increase compliance, and they should target stores that are reliant on tobacco sales.

A study was performed to determine whether cigarettes were smoked more intensely outside of public venues in Scotland, compared to indoors, after introduction of the public place smoking (PPS) ban. It was conducted in three waves: before the ban, immediately after and 6 months after introduction. The study included 322 regular smokers of four cigarette brand variants. Filter analysis measurements were used to estimate the human-smoked yields of tar and nicotine from cigarettes smoked predominantly inside (before the ban) or outside (after the ban) public venues. Self-reported cigarette consumption data were also collected. Numbers of cigarettes smoked indoors in public places fell dramatically after the ban. There was a corresponding rise in smoking incidence in outdoor public locations. The ban did not significantly affect the total number of cigarettes smoked by the subjects over the weekends investigated. Human-smoked yields of tar and nicotine decreased slightly after the introduction of the ban and some reductions were significant. Therefore, smoking outdoors at public venues, following the PPS ban, did not increase smoking intensity. Any changes in smoking behaviour that may have occurred had little effect on mainstream smoke exposure or cigarette consumption for those that continued to smoke. Copyright © 2010 Elsevier Inc.

Different publications have described a close relation between tobacco consumption and major psychiatric disorders. A great number of countries have enacted smoking bans in public or working places since the early 2000s; nonetheless, concerns remain over the exemption in some psychiatric settings regarding smoking bans. Admission of smokers to smoke-free units may lead to behavior deterioration, but some recent evidence refutes this argument. Literature review. One of the earliest smoking bans was a 1.575 Mexican ecclesiastical council ban aimed at smoking prevention in churches. Several recent studies have documented health and economic benefits related to smoking bans. Over 83 countries now have introduced different sorts of regulations. There was no increase in aggression, seclusion or discharge against medical advice, neither increased use of PRN (as needed) medication following the ban. As part of the ban imposition, Nicotine Replacement Therapy- NRT was used by patients. Consistency, coordination and full staff support for the ban were seen as key success factors. Many patients continued smoking after discharge. Evidence shows that smoking has no place in psychiatric hospitals or facilities. The introduction of smoking bans in psychiatric settings is possible, but these bans must be conceived only as part of a much larger strategy, necessary to diminish smoking high rates among mental health populations.

Tobacco-free policies on college campuses are spreading in Korea. However, the impact of the smoking ban legislation at venues on the boundary of a college campus is still limited. This study aimed to assess short-term changes in PM2.5 concentrations before and after the enactment of the smoking ban legislation to evaluate the impact. In this cross-sectional study, PM2.5 measurements (pre-ban: n = 99, post-ban: n = 64) were conducted in randomly selected billiards, pubs, and computer game rooms on the peripheries of college campuses in October 2013, prior to implementation of the smoking ban, and in May 2014, after the ban. The median (interquartile range, IQR) of the PM2.5 concentration for all venues was 31 μg/m3 (0–80 μg/m3) in the pre-ban period and 11 μg/m3 (0–36 μg/m3) in the post-ban period implying indoor PM2.5 concentration levels of the peripheries of college campuses likely decreased one year after implementation of the ban. However, the differences were not significant yet. The results support the introduction of more rigorous monitoring of SHS exposure levels toward the ultimate goal of encouraging a complete smoking ban in hospitality venues, including billiards, pubs, and computer game rooms located on the peripheries of college campuses.

Internet cigarette vendor compliance with credit card payment and shipping bans.

PubMed

Williams, Rebecca S; Ribisl, Kurt M

2014-02-01

Most Internet cigarette sales have violated taxation and youth access laws, leading to landmark 2005 agreements with credit card companies, PayPal, and private shippers (United Parcel Service, Federal Express, DHL) to cease participation in these transactions. Despite their promise at the time, loopholes allowed for check payment and U.S. Postal Service (USPS) shipping. This study assessed actual vendor compliance with the payment and shipping bans using a purchase survey. In late 2007 and early 2008, an adult buyer attempted to order cigarettes from the 97 most popular Internet cigarette vendors (ICVs) using banned payment and shipping methods. When banned payment or shipping methods were unavailable, purchases were attempted with alternate methods (e.g., checks, e-checks, USPS). Twenty-seven of 100 orders were placed with (banned) credit cards; 23 were successfully received. Seventy-one orders were placed with checks (60 successfully received). Four orders were delivered using banned shippers; 79 of 83 successfully received orders were delivered by the USPS. About a quarter of ICVs violated the payment ban, others adapted by accepting checks. Most vendors complied with the shipping ban, perhaps because USPS was an easy substitute shipping option. Better enforcement of the bans is needed; the 2009 Prevent All Cigarette Trafficking Act closed the USPS loophole by making cigarettes nonmailable material; evaluation of enforcement efforts and adaptations by vendors are needed. These sorts of bans are a promising approach to controlling the sale of restricted goods online.

We aimed to evaluate the knowledge and perspective of employees/employers in the catering sector in our city regarding the smoking ban, as well as to determine the changes in the number of customers and income after the bans implementation. In this two phased cross-sectional study 337 and 310 adults were evaluated respectively. Before the smoking ban was implemented we visited 84 workplaces in city center, after 18 months later 97 workplaces were visited in the same region. In both phases, the participants' opinions about the necessity/applicability of the ban were evaluated. In the second phase, they were also asked whether they had any changes in their income. In both phases, participants' general characteristics were similar. When all participants were evaluated, we determined that their knowledge and belief in the necessity/applicability of the ban did not change over time. It was determined that non-smokers more strongly believed in the necessity/applicability of the ban. Thirty-eight participants were included in both phases; 44.7% of them reported a decrease in the number of customers, and 60% of employers reported an increase in their income. The smokers were less convinced about the applicability/necessity of this ban than non-smokers. According to our results it could be said that smoking can also adversely affect implementation of the related ban. Employers should be informed that the ban will not affect their income.

2012-01-01

Policies restricting indoor worksite tobacco use began being implemented more than a decade ago. More recently, the scope of these policies has been expanding to outdoors, with hospitals leading the trend in restricting smoking throughout their grounds. However, research on the effects such bans have on employees is scarce. The purpose of the current study was to examine the impact of a campus-wide smoking ban on employees and patients at a cancer center. Employees completed anonymous questionnaires during the months before (n = 607; 12% smokers) and 3 months after the ban implementation (n = 511; 10% smokers). Patients (n = 278; 23% smokers) completed an anonymous questionnaire preban. Results showed that 86% of nonsmokers, 20% of employees who smoke, and 57% of patients who smoke supported the ban. More than 70% of smokers were planning or thinking about quitting at both time points and nearly one-third were interested in cessation services following the ban. Before the ban, 32% expected the ban to have a negative effect on job performance and 41% thought their smoking before and after work would increase. Postban, 22% reported a negative impact on job performance, 35% increased smoking before and after work, and 7% quit. Overall, these data revealed an overwhelming support for an outdoor smoking ban by nonsmoker employees and patients. Although a majority of employee smokers opposed the ban, a significant proportion was interested in cessation. Compared with preban expectations, a lower proportion experienced negative effects postban. Findings suggest a need for worksite cessation programs to capitalize on the window of opportunity created by tobacco bans, while also addressing concerns about effects on work performance.

“How Is Smoking Handled in Your Home?”: Agreement Between Parental Reports on Home Smoking Bans in the United States, 1995–2007

Zhang, Xiao; Kuo, Daphne; Jones, Nathan R.

2012-01-01

Introduction: Home smoking bans significantly reduce secondhand smoke exposure among children, but parents may offer discordant reports on whether there is a home smoking ban. The purpose of this study was to examine national trends in (a) parental discordance/concordance in the reporting of home smoking bans and (b) correlates of discordant/concordant reports among two-parent households with underage children from 1995 to 2007. Methods: Data from the 1995/1996, 1998/1999, 2001/2002, 2003, and 2006/2007 Tobacco Use Supplement of the U.S. Current Population Survey were used to estimate prevalence rates and multinomial logistic regression models of discordant/concordant parental smoking ban reports by survey period. Results: Overall, the percentage of households in which the 2 parents gave discordant reports on a complete home smoking ban decreased significantly from 12.7% to 2.8% from 1995 to 2007 (p < .001). Compared with households where both parents reported a complete smoking ban, discordant reports were more likely to be obtained from households with current smokers (p < .01) across survey periods. Compared with households where both parents reported the lack of a complete home smoking ban, discordant reports were more likely among households with college graduates, no current smokers, and parents with Hispanic ethnicity (p < .05). Conclusions: Parental concordance on the existence of a home smoking ban increased from 1995 to 2007. This suggests estimates of home smoking bans based on just one parent may be more reliable now than they were in the past. Interventions to improve the adoption and enforcement of home smoking bans should target households with current smoker parents. PMID:22377935

Thirdhand Smoke in the Homes of Medically Fragile Children: Assessing the Impact of Indoor Smoking Levels and Smoking Bans

Abstract Introduction: Thirdhand smoke (THS) residue results from secondhand smoke, and is emerging as a distinct public health hazard, particularly for medically fragile pediatric patients living with smokers. THS is difficult to remove and readily reacts with other pollutants to form carcinogens and ultrafine particles. This study investigated THS found in homes of high-risk infants admitted to a neonatal intensive care unit and their association with characteristics (eg, number of household smokers) hypothesized to influence THS. Methods: Baseline data from 141 hospitalized infants’ homes were analyzed, along with follow-up data ( n = 22) to explore household smoking characteristics and THS changes in response to indoor smoking ban policies. Results: Households with an indoor ban, in which not more than 10 cigarettes/d were smoked, had the lowest levels of THS contamination compared to homes with no ban ( P < .001) and compared to homes with an indoor ban in which greater numbers of cigarettes were smoked ( P < .001). Importantly, homes with an indoor ban in which at least 11 cigarettes/d were smoked were not different from homes without a ban. The follow-up sample of 22 homes provided initial evidence indicating that, unless a ban was implemented, THS levels in homes continued to increase over time. Conclusions: Preliminary longitudinal data suggest that THS may continue to accumulate in homes over time and household smoking bans may be protective. However, for homes with high occupant smoking levels, banning indoor smoking may not be fully adequate to protect children from THS. Unless smoking is reduced and bans are implemented, medically fragile children will be exposed to the dangers of THS. PMID:26315474

In this study we compared indoor air pollutant concentrations in a bar/restaurant in Greece before and after the enactment of a smoking ban legislation of 2008. This was done to investigate whether the separation of the venue into smoking and non-smoking areas will have an impact on workers and customers from secondhand smoke (SHS) exposure (null hypothesis). The study was completed within an 8-month period beginning in March 2010 and ending on November 2010. We compared the average of the measured PM0.1 concentrations in the smoking zones between the pre-ban and post-ban periods. Overall reduction in the number of particles was 18% between pre-ban and post-ban periods. The mean of the 36 total CO2 measurements for the pre- and the post-ban period was 611ppm. We calculated the ventilation rates per occupant (Vo in l/s/occ) and found it to be higher in the post-ban period (19.4l/s/occ), thus complying with the ASHARAE standard for Vo of 15l/s/occ at maximum occupancy, than in the pre-ban period (10.7l/s/occ). The mean of the 36 total CO measurements for the pre-ban period was 2 ppm. CO measurements in the post-ban period were less than the detection limit of 1 ppm. Emissions of nitrogen dioxide and formaldehyde weren't detected in any of the zones. It was observed there was about 50% distribution of pollutants from the smoking zones to the smoke-free zones. The smoking ban effect on the occupancy levels was initially reduced by 16%, but based on other similar studies this transition period will be followed by an increase in the occupancy. Passive smoking and associated risks were significantly reduced but not totally eliminated, indicating the need for stronger enforcement or complete partition between smoking and non-smoking areas.

Research evaluating enforcement and compliance with smoking partial bans is rather scarce, especially in countries with relative weak tobacco control policies, such as Portugal. There is also scarce evidence on specific high risk groups such as vehicle workers. In January 2008, Portugal implemented a partial ban, followed by poor enforcement. The purpose of this study was to explore the effectiveness of a partial smoking ban in a pro-smoking environment, specifically transportation by taxi in the city of Lisbon. Ban effectiveness was generally defined by ban awareness and support, compliance and enforcement. Exploratory cross-sectional study; purposive sampling in selected Lisbon streets. Structured interviews were conducted by trained researchers while using taxi services (January 2009-December 2010). 250 taxi drivers (98.8% participation rate). Chi-square, McNemar, Man Whitney tests and multiple logistic regression were performed. Of the participants, 249 were male; median age was 53.0 years; 43.6% were current smokers. Most participants (82.8%) approved comprehensive bans; 84.8% reported that clients still asked to smoke in their taxis; 16.8% allowed clients to smoke. Prior to the ban this value was 76.9% (p < 0.001). The major reason for not allowing smoking was the legal ban and associated fines (71.2%). Of the smokers, 66.1% admitted smoking in their taxi. Stale smoke smells were detected in 37.6% of the cars. None of the taxi drivers did ever receive a fine for non-compliance. Heavy smoking, night-shift and allowing smoking prior the ban predicted non-compliance. Despite the strong ban support observed, high smoking prevalence and poor enforcement contribute to low compliance. The findings also suggest low compliance among night-shift and vehicle workers. This study clearly demonstrates that a partial and poorly-enforced ban is vulnerable to breaches, and highlights the need for clear and strong policies.

Compliance and enforcement of a partial smoking ban in Lisbon taxis: an exploratory cross-sectional study

2013-01-01

Background Research evaluating enforcement and compliance with smoking partial bans is rather scarce, especially in countries with relative weak tobacco control policies, such as Portugal. There is also scarce evidence on specific high risk groups such as vehicle workers. In January 2008, Portugal implemented a partial ban, followed by poor enforcement. The purpose of this study was to explore the effectiveness of a partial smoking ban in a pro-smoking environment, specifically transportation by taxi in the city of Lisbon. Ban effectiveness was generally defined by ban awareness and support, compliance and enforcement. Methods Exploratory cross-sectional study; purposive sampling in selected Lisbon streets. Structured interviews were conducted by trained researchers while using taxi services (January 2009-December 2010). Participants: 250 taxi drivers (98.8% participation rate). Chi-square, McNemar, Man Whitney tests and multiple logistic regression were performed. Results Of the participants, 249 were male; median age was 53.0 years; 43.6% were current smokers.

To evaluate the knowledge and manner of cafe, pub and restaurant (with/without alcohol) workers in our city center about the ban on restriction of indoor smoking. To determine the preparation about the ban, smoking characteristics of workers, the knowledge on passive smoking. A questionnaire was performed to workers. The type of workplace, the number of workers, existence of a restriction of indoor smoking, any preparation about the ban were asked. The job of worker, whether the worker has a knowledge on the ban or not, the idea of the workers on the necessity and practicability of the ban were asked. Smoking history and the knowledge about passive smoking of workers were recorded. Fagerstrom nicotine dependent test (FNDT) was performed to smokers. Eighty four work places with 568 workers included in the study. The questionnaire was performed to 337 workers whose mean age was 29.1/years. 292 of workers were male. 190 of cases were current smokers. 166 of cases (49.3%) know the meaning of passive smoking. Alcohol offering was made at 8 of workplaces. Smoking was forbidden in 20 of workplaces. A preparation was performed about the ban in 30 of (46.9%) other workplaces. 88.4% of workers have knowledge on the ban, 64.7% of them know the punishment of the noncompliance of the ban. 81.3% of the workers believe the necessity and 45.7% of them believe the practicability of the ban. Smokers and especially who's FNBT > 5 have a stronger belief on the necessity and practicability of the ban. We determined that the preparation about the ban was inadequate although there was an little time for the put into practice the law. So we think that the controls of workplaces should be happened frequent.

Sodas are widely sold in vending machines and other school venues in the United States, particularly in high school. Research suggests that policy changes have reduced soda access, but the impact of reduced access on consumption is unclear. This study was designed to identify student, environmental, or policy characteristics that modify the associations between school vending machines and student dietary behaviors. Data on school vending machine access and student diet were obtained as part of the National Youth Physical Activity and Nutrition Study (NYPANS) and linked to state-level data on soda taxes, restaurant taxes, and state laws governing the sale of soda in schools. Regression models were used to: 1) estimate associations between vending machine access and soda consumption, fast food consumption, and lunch source, and 2) determine if associations were modified by state soda taxes, restaurant taxes, laws banning in-school soda sales, or student characteristics (race/ethnicity, sex, home food access, weight loss behaviors.). Contrary to the hypothesis, students tended to consume 0.53 fewer servings of soda/week (95% CI: -1.17, 0.11) and consume fast food on 0.24 fewer days/week (95% CI: -0.44, -0.05) if they had in-school access to vending machines. They were also less likely to consume soda daily (23.9% vs. 27.9%, average difference  =  -4.02, 95% CI: -7.28, -0.76). However, these inverse associations were observed primarily among states with lower soda and restaurant tax rates (relative to general food tax rates) and states that did not ban in-school soda sales. Associations did not vary by any student characteristics except for weight loss behaviors. Isolated changes to the school food environment may have unintended consequences unless policymakers incorporate other initiatives designed to discourage overall soda consumption.

Body Area Network (BAN) is considered as a promising technology in supporting medical and healthcare services by combining with various biological sensors. In this paper, we look at wearable BAN, which provides communication links among sensors on body surface. In order to design a BAN that manages biological information with high efficiency and high reliability, the propagation characteristics of BAN must be thoroughly investigated. As a preliminary effort, we measured the propagation characteristics of BAN at frequency bands of 400MHz, 600MHz, 900MHz and 2400MHz respectively. Channel models for wearable BAN based on the measurement were derived. Our results show that the channel model can be described by using a path loss model for all frequency bands investigated.

Indoor tanning is a known risk factor for skin cancer and is especially dangerous for adolescents. Some states have passed indoor tanning bans for minors, but business compliance with the bans is not well understood. Thus far, studies have assessed ban compliance in one or two states at a time. This study aimed to assess compliance with indoor tanning bans for minors and knowledge of dangers and benefits of tanning among indoor tanning businesses. Female research assistants posing as minors telephoned a convenience sample of 412 businesses in 14 states with tanning bans for minors under age 17 or 18. We evaluated differences in compliance by census region and years since ban was implemented and differences in reported dangers and benefits by compliance. Most (80.1%) businesses told the "minor" caller she could not use the tanning facilities. Businesses in the south and in states with more recent bans were less compliant. Among those (n = 368) that completed the full interview, 52.2% identified burning and 20.1% mentioned skin cancer as potential dangers. However, 21.7% said dangers were no worse than the sun and 10.3% denied any dangers. Stated benefits included vitamin D (27.7%), social/cosmetic (27.2%), and treats skin diseases (26.4%), with only 4.9% reporting no benefits. While most businesses followed the indoor tanning ban when a minor called, one-fifth did not. Many stated inaccurate health claims. Additional enforcement or education might increase compliance with indoor tanning bans and action is needed to prevent businesses from stating false health information.

The population's attitude towards smoking bans in public arenas is important for their passing, implementation and compliance. Smoking bans are believed to reduce the social acceptability of smoking, and once people experience them, public support increases--also among pre-ban sceptics. This study aimed to examine the temporal changes in public attitude towards smoking bans in public arenas from 2007 to 2010 and whether these changes differed across educational attainment, smoking status and intention to quit among smokers. Data from two surveys among adults (aged 25-79 years) in 2007 and 2010 in the Capital Region of Denmark (n=36,472/42,504, response rate = 52.3) was linked with data on sex, age and educational attainment from central registers. Age-standardised prevalence of supportive attitude towards smoking bans was estimated. Temporal changes in supportive attitude were explored in workplaces, restaurants and bars using logistic regression models. The prevalence of supportive attitude towards smoking bans increased significantly in all arenas from 2007 to 2010. Positive temporal changes in supportive attitude towards smoking bans were seen across educational attainment, smoking status and intention to quit smoking in restaurants and across smoking status for smoking bans in workplaces and bars. The results of this study show that the public's attitude towards smoking in public arenas has changed after the implementation of a comprehensive smoking ban. This change in attitude can support implementation of future legislation on smoking and may lead to positive changes in smoking norms. © 2014 the Nordic Societies of Public Health.

The ban on "off-label" pharmaceutical promotion: constitutionally permissible prophylaxis against false or misleading commercial speech?

PubMed

Greenwood, Kate

2011-01-01

Critics of the Food & Drug Administration's ban on off-label promotion often claim that it violates the First Amendment because it suppresses pharmaceutical manufacturers' truthful speech about their legal--and beneficial--products. Characterizing the ban on off-label promotion in this way has more than rhetorical significance. Bans on truthful, non-misleading speech elicit special skepticism because of the belief that they "usually rest solely on the offensive assumption that the public will respond 'irrationally' to the truth." The legislative history of the provisions of the Food Drug and Cosmetic Act that underlie the ban on off-label promotion, however, reveals that Congress was concerned that physicians were responding rationally to false and misleading promotional claims. In this Article, I explore the doctrinal questions raised by conceiving of the ban on off-label promotion not as a ban on "truthful speech to physicians" but instead as a prophylaxis against false and misleading pharmaceutical promotion. I review the evidence that false and misleading claims were commonplace before the ban's adoption and persist today, along with the enforcement challenges the FDA confronted at that time and would confront were the ban lifted, and conclude the government likely could develop the factual record necessary to establish that Congress' rejection of an after-the-fact case-by-case approach to combating false and misleading prescription drug promotion is constitutional.

To determine which distracted driving laws were associated with decreased texting while driving among U.S. teenage drivers. Data from the 2013 Youth Risk Behavior Surveillance System survey were merged with states' distracted driving legislation. The prevalence of texting while driving was assessed for different laws using log-binomial regression. Approximately 39.0% of students reported texting while driving at least once in the 30 days before survey. Compared to states with universal texting bans along with young driver all cellphone bans, the adjusted ratio of texting while driving was 0.94 (95% confidence interval [CI], 0.77-1.16) in states with no bans, 1.33 (95% CI, 1.11-1.58) for young driver bans only, 1.24 (95% CI, 1.00-1.52) in states with bans for young drivers but no young driver all cellphone bans, and 0.89 (95% CI, 0.66-1.19) in states with universal texting bans. The prevalence of texting was 28% less in states with delays of full licensure for texting offenses (prevalence ratio = 0.72; 95% CI, 0.59-0.88). Universal texting bans along with young driver all cellphone bans may be more effective in reducing texting while driving. Delays of full licensure may dissuade young drivers from texting and driving. Copyright © 2015 Elsevier Inc. All rights reserved.

FCTC followed by accelerated implementation of tobacco advertising bans.

PubMed

Hiilamo, Heikki; Glantz, Stanton

2017-07-01

We sought to evaluate changes in countries' enacting advertising bans after the effect of ratifying the WHO Framework Convention on Tobacco Control (FCTC). We compared adoption of advertising bans on five areas (TV and radio, print media, billboards, point-of-sale, sponsorship) in countries that did versus did not ratify the FCTC, accounting for years since the ratification of the Convention. On average, passage of complete advertising bans accelerated after FCTC ratification. The development was strongest among lower middle-income countries. Lack of state capacity was associated with lower likelihood of countries implementing complete advertising bans. Implementation of complete advertising bans slowed after 2007. Implementation of FCTC Article 13 was followed by increased progress towards complete advertising bans, but progress is incomplete, especially among low-income countries. Low-income countries need comprehensive support to implement FCTC as part of a broad effort to reinvigorate progress on global implementation of the FCTC. Enforcing complete bans requires constant monitoring and attacking of tobacco industry efforts to circumvent them. Published by the BMJ Publishing Group Limited.

The costs and benefits of a cigarette ban.

PubMed

Doucet, Mathieu

2017-06-01

The death toll from tobacco is staggering: it might contribute to one billion premature deaths over the course of the 21st century. In 'The case for banning cigarettes', Kalle Grill and Kristin Voigt argue that the well-being and equality benefits of a complete ban on cigarettes more than justify the restrictions on autonomy that such a ban would impose. Their argument depends on two crucial simplifications: an assumption that the ban would be effective and the restriction of the analysis to a comparison with the status quo, rather than a broader range of policy options. I argue that despite the authors' claims, these two simplifications make it impossible for their argument to 'bring into focus the fundamental normative issues' surrounding a possible cigarette ban, since they dramatically overstate the benefits and obscure the most significant costs of such a ban.

A total ban on alcohol advertising: presenting the public health case.

PubMed

Parry, Charles; Burnhams, Nadine Harker; London, Leslie

2012-05-28

Evidence from burden of disease and economic costing studies amply indicate that the public health burden from hazardous and harmful use of alcohol in South Africa warrants drastic action. Evidence that banning alcohol advertising is likely to be an effective intervention is reflected in WHO strategy documents on non-communicable diseases and harmful use of alcohol. Studies on young people furthermore support arguments refuting the claim that advertising only influences brand choice. Given the weakness of relying on industry self-regulation, the government is considering legislation to ban alcohol advertising, resulting in heated debate. Tobacco control and studies investigating the effect of alcohol advertising bans on consumption and alcohol-related deaths point to the effectiveness of such action - ideally supplemented by other policy interventions. Arguments against an advertising ban include possible communication sector job losses, but these are likely to have been exaggerated. Banning alcohol advertising will necessitate greater scrutiny of digital media, satellite television and merchandising to reduce the likelihood of subverting the ban.

Reduced admissions for acute myocardial infarction associated with a public smoking ban: matched controlled study.

2007-01-01

There has been no research linking implementation of a public smoking ban and reduced incidence of acute myocardial infarction (AMI) among nonsmoking patients. An ex post facto matched control group study was conducted to determine whether there was a change in hospital admissions for AMI among nonsmoking patients after a public smoking ban was implemented in Monroe County compared with Delaware County, Indiana without such a ban. Poisson analysis was conducted for 44 months of hospital admissions. A significant drop occurred in the number of admissions among nonsmoking patients in Monroe County after the ban whereas a nonsignificant decrease in the number of admissions occurred in Delaware County. The changes in the number of smoking-patient admissions before and after the ban were not significant.

Effectiveness of state and federal government agreements with major credit card and shipping companies to block illegal Internet cigarette sales.

Most Internet vendors offer tax-free cigarettes making them cheaper than those sold at stores. This undermines the impact that higher prices have upon reducing consumption. Most Internet tobacco sales have violated taxation and youth access laws, which led to landmark voluntary agreements in 2005 with the major credit card companies and major private shippers to ban payment transactions and shipments for all Internet cigarette sales. To assess whether these bans increased the rate of Internet Cigarette Vendors (ICVs) ceasing online sales, decreased the proportion of vendors offering banned payment and shipping options, and decreased consumer traffic to the most popular ICVs. Websites in a longitudinal study of ICVs were visited in 2003 (n = 338), 2004 (n = 775), 2005 (n = 664), 2006 (n = 762), and 2007 (n = 497) to assess whether they were in business and monitor their advertised sales practices. The number of unique monthly visitors to the 50 most popular ICVs at baseline was examined for the period one year before and two years after the bans to determine whether the bans altered traffic. Following the bans, the rate of ICVs ceasing online sales year to year increased, but due to an influx of new vendors, there was a net increase in ICVs. The proportion of vendors accepting banned payment options dropped from 99.2% to 37.4% after the bans, and the proportion offering banned shipping options dropped from 32.2% to 5.6%, but there was a corresponding increase in vendors offering non-banned payment options (e.g., personal checks) and shipping options (e.g., US Postal Service). Following the bans, there was a 3.5 fold decline in traffic to the most popular ICV websites. This promising approach to controlling the sale of restricted goods online has implications for regulating other products such as alcohol, firearms, quack cures, and medicines sold without a prescription.

2010-04-01

As of October 2009, seven U.S. states and the District of Columbia (D.C.) ban driving while talking on a handheld cell phone. Long-term effects on driver handheld phone use in D.C., New York State, and Connecticut were examined. The percentage of drivers talking on handheld cell phones was measured over time with daytime observation surveys in the jurisdictions with bans and comparison jurisdictions without bans. Trends were modeled using Poisson regression to estimate differences between actual rates and rates that would have been expected without a ban. The D.C. ban immediately lowered the percentage of drivers talking on handheld cell phones by 41 percent. Nearly 5 years later, the rate was 43 percent lower than would have been expected without the ban. Use in Connecticut declined 76 percent immediately after the ban; 3.5 years later, use was 65 percent lower than would have been expected without the ban. In New York, use declined 47 percent immediately after the ban; 7 years later, use was 24 percent lower than expected without the ban. Fifteen months after the laws took effect, compliance in New York was lower than in D.C., and the difference appeared due to more intensive enforcement in D.C. However, this linkage is no longer clear because enforcement in New York picked up such that 2008 levels of enforcement appeared comparable in D.C. and New York, whereas enforcement in Connecticut lagged behind. In all three jurisdictions, the chance that a violator would receive a citation was low, and there were no publicized targeted enforcement campaigns. Jurisdictional bans have reduced handheld phone use and appear capable of maintaining reductions for the long term. However, it is unknown whether overall phone use is lower because many drivers may have switched to hands-free devices. Further research is needed to determine whether reduced handheld cell phone use has reduced crashes.

Baicalin is one of the main bioactive flavone glucuronides derived as a medicinal herb from the dried roots of Scutellaria baicalensis Georgi, and it is widely used for the treatment of fever, inflammation, and other conditions. Due to baicalin’s poor solubility in water, its absolute bioavailability after oral administration is only 2.2%. The objective of this study was to develop a novel baicalin-loaded nanoemulsion to improve the oral bioavailability of baicalin. Based on the result of pseudoternary phase diagram, the nanoemulsion formulation consisting of soy-lecithin, tween-80, polyethylene glycol 400, isopropyl myristate, and water (1:2:1.5:3.75:8.25, w/w) was selected for further study. Baicalin-loaded nanoemulsions (BAN-1 and BAN-2) were prepared by internal or external drug addition and in vivo and in vitro evaluations were performed. The results showed that the mean droplet size, polydispersity index, and drug content of BAN-1 and BAN-2 were 91.2 ± 2.36 nm and 89.7 ± 3.05 nm, 0.313 ± 0.002 and 0.265 ± 0.001, and 98.56% ± 0.79% and 99.40% ± 0.51%, respectively. Transmission electron microscopy revealed spherical globules and confirmed droplet size analysis. After dilution 30-fold with water, the solubilization capacity of BAN-1 and BAN-2 did not change. In vitro release results showed sustained-release characteristics. BAN-1 formulation was stable for at least 6 months and was more stable than BAN-2. In rats, the area under the plasma drug concentration-time curve value of BAN-1 was 1.8-fold and 7-fold greater than those of BAN-2 and free baicalin suspension after oral administration at a dose of 100 mg/kg. In conclusion, these results demonstrated that the baicalin-loaded nanoemulsion formulation, in particular BAN-1, was very effective for improving the oral bioavailability of baicalin and exhibited great potential for future clinical application.

The study was performed in 14 provinces in Spain. Hospital admission records were collected for acute myocardial infarction (AMI), ischemic heart disease (IHD), and cerebrovascular disease (CVD) in patients aged ≥ 18 years from 2003 through 2012. We estimated immediate and 1-year effects with segmented-linear models. The coefficients for each province were combined using random-effects multivariate meta-analysis models. Overall, changes in admission rates immediately following the implementation of the partial ban and 1 year later were -1.8% and +1.2% for AMI, +0.1 and +0.4% for IHD, and +1.0% and +2.8% for CVD (P>.05). After the comprehensive ban, immediate changes were -2.3% for AMI, -2.6% for IHD, and -0.8% for CVD (P>.05), only to return to precomprehensive ban values 1 year later. For patients aged ≥ 65 years of age, immediate changes associated with the comprehensive ban were -5.0%, -3.9%, and -2.3% for AMI, IHD, and CVD, respectively (P<.05). Again, the 1-year changes were not statistically significant. In Spain, smoking bans failed to significantly reduce hospitalizations for AMI, IHD, or CVD among patients ≥ 18 years of age. In the population aged ≥ 65 years, hospital admissions due to these diseases showed significant decreases immediately after the implementation of the comprehensive ban, but these reductions disappeared at the 1-year evaluation.

Many countries have introduced legislations for public smoking bans to reduce the harmful effects of exposure to tobacco smoke. Smoking bans cause significant reductions in admissions for acute coronary syndromes but their impact on respiratory diseases is unclear. In Geneva, Switzerland, two popular votes led to a stepwise implementation of a state smoking ban in public places, with a temporary suspension. This study evaluated the effect of this smoking ban on hospitalisations for acute respiratory and cardiovascular diseases. This before and after intervention study was conducted at the University Hospitals of Geneva, Switzerland, across 4 periods with different smoking legislations. It included 5,345 patients with a first hospitalisation for acute coronary syndrome, ischemic stroke, acute exacerbation of chronic obstructive pulmonary disease, pneumonia and acute asthma. The main outcomes were the incidence rate ratios (IRR) of admissions for each diagnosis after the final ban compared to the pre-ban period and adjusted for age, gender, season, influenza epidemic and secular trend. Hospitalisations for acute exacerbation of chronic obstructive pulmonary disease significantly decreased over the 4 periods and were lowest after the final ban (IRR=0.54 [95%CI: 0.42-0.68]). We observed a trend in reduced admissions for acute coronary syndromes (IRR=0.90 [95%CI: 0.80-1.00]). Admissions for ischemic stroke, asthma and pneumonia did not significantly change. A legislative smoking ban was followed by a strong decrease in hospitalisations for acute exacerbation of chronic obstructive pulmonary disease and a trend for reduced admissions for acute coronary syndrome. Smoking bans are likely to be very beneficial for patients with chronic obstructive pulmonary disease.

Background Despite the tremendous economic and health costs imposed on China by tobacco use, China lacks a proactive and systematic tobacco control surveillance and evaluation system, hampering research progress on tobacco-focused surveillance and evaluation studies. Methods This paper uses online search query analyses to investigate changes in online search behavior among Chinese Internet users in response to the adoption of the national indoor public place smoking ban. Baidu Index and Google Trends were used to examine the volume of search queries containing three key search terms “Smoking Ban(s),” “Quit Smoking,” and “Electronic Cigarette(s),” along with the news coverage on the smoking ban, for the period 2009–2011. Findings Our results show that the announcement and adoption of the indoor public place smoking ban in China generated significant increases in news coverage on smoking bans. There was a strong positive correlation between the media coverage of smoking bans and the volume of “Smoking Ban(s)” and “Quit Smoking” related search queries. The volume of search queries related to “Electronic Cigarette(s)” was also correlated with the smoking ban news coverage. Interpretation To the extent it altered smoking-related online searches, our analyses suggest that the smoking ban had a significant effect, at least in the short run, on Chinese Internet users’ smoking-related behaviors. This research introduces a novel analytic tool, which could serve as an alternative tobacco control evaluation and behavior surveillance tool in the absence of timely or comprehensive population surveillance system. This research also highlights the importance of a comprehensive approach to tobacco control in China. PMID:23776504

Comprehensive bans on tobacco advertising and promotion were introduced through tobacco control legislation in Viet Nam, but it has been established that violations of the bans are very common. This study was conducted to explore the trend in violations of bans on tobacco advertising and promotion at points of sale in Viet Nam in the past six years and to explore any differences in the violation situations before and after the Law on Tobacco Control came into effect on 1st May 2013. Quantitative data were collected through observation of violations of the bans on tobacco advertising and promotion at points of sale in 10 provinces throughout Viet Nam in four survey rounds (2009, 2010, 2011, and 2015). Variation in violation prevalence over time was examined by chi-square test using a Bonferini method. Binary logistic regression was employed to identify the factors that may have influences on different types of violation. A level of significance of p<0.05 was used for all tests in this article. The most common form of violation was the display of more than one pack/one carton of a cigarette brand. Violation of bans on tobacco advertising increased while violations on promotion ban and on displaying tobacco decreased through time. Some factors associated with the tobacco advertising and promotion bans included surveyed years, types of points of sale, regions and areas where the points of sale were located. The enforcement of the bans did not improve even after the issuance and the enactment of the Law on Tobacco Control. This suggests that the monitoring and enforcement of bans on tobacco advertising and promotion at points of sale should be strengthened. Penalties should be strictly applied for violators as indicated in the current tobacco control legislation.

To investigate whether smoke-free legislation in the Netherlands led to a decreased incidence of out-of-hospital sudden circulatory arrest (SCA). Smoke-free legislation was implemented in two phases: a workplace ban in 2004 and an extension of this ban to the hospitality sector on 1 July 2008. Weekly incidence data on SCA were obtained from the ambulance registry of South Limburg, the Netherlands. Three time periods were distinguished: the pre-ban period (1 January 2002-1 January 2004), the first post-ban period (1 January 2004-1 July 2008) and the second post-ban period (1 July 2008-1 May 2010). Trends in absolute SCA incidence were analysed using Poisson regression, adjusted for population size, ambient temperature, air pollution and influenza rates. A total of 2305 SCA cases were observed (mean weekly incidence 5.3±2.3 SD). The adjusted Poisson regression model showed a small but significant increase in SCA incidence during the pre-ban period (+0.20% cases per week, p=0.044). This trend changed significantly after implementation of the first ban (with -0.24% cases per week, p=0.043), translating into a 6.8% (22 cases) reduction in the number of SCA cases after 1 year of smoke-free legislation. No further decrease was seen after the second smoking ban. After introduction of a nationwide workplace smoking ban in 2004, a significant decrease in the incidence of out-of-hospital SCA was seen in South Limburg. Poor enforcement of the 2008 hospitality sector ban may account for the fact that no further decrease in the incidence of SCA was seen at this time.

Spain implemented a partial smoking ban in 2006 followed by a comprehensive ban in 2011. The objective was to examine the association between these smoke-free policies and different perinatal complications. Cross-sectional study including all live births between 2000 and 2013. Selected adverse birth outcomes were: preterm births (<37 gestational weeks), small for gestational age (SGA; <10th weight percentile according to Spanish reference tables), and low birth weight (<2500 g). We estimated immediate and gradual rate changes after smoking bans by using overdispersed Poisson models with different linear trends for 2000 to 2005 (preban), 2006 to 2010 (partial ban), and 2011 to 2013 (comprehensive ban). Models were adjusted for maternal sociodemographics, health care during the delivery, and smoking prevalence during pregnancy. The comprehensive ban was associated with preterm birth rate reductions of 4.5% (95% confidence interval [CI]: 2.9%-6.1%) and 4.1% (95% CI: 2.5%-5.6%) immediately and 1 year after implementation, respectively. The low birth weight rate also dropped immediately (2.3%; 95% CI: 0.7%-3.8%) and 1 year after the comprehensive ban implementation (3.5%; 95% CI: 2.1%-5.0%). There was an immediate reduction in the SGA rate at the onset of the partial ban (4.9%; 95% CI: 3.5%-6.2%), which was sustained 1 year postimplementation. Although not associated with the comprehensive ban at the onset, the SGA rate declined by 1.7% (95% CI: 0.3%-3.1%) 1 year postimplementation. The implementation of the Spanish smoke-free policies was associated with a risk reduction for preterm births and low birth weight infants, especially with the introduction of the more restrictive ban.

In February 2003, a comprehensive ban on tobacco promotion came into effect in the United Kingdom, which prohibited tobacco marketing through print and broadcast media, billboards, the internet, direct mail, product placement, promotions, free gifts, coupons and sponsorships. To investigate the impact of the UK's comprehensive ban on tobacco promotion on adult smokers' awareness of tobacco marketing in the UK relative to Canada, the United States and Australia. A total of 6762 adult smokers participated in two waves of a random digit dialled telephone survey across the four countries. Wave 1 was conducted before the UK ban (October-December 2002) and Wave 2 was conducted after the UK ban (May-September 2003). Awareness of a range of forms of tobacco marketing. Levels of tobacco promotion awareness declined significantly among smokers in the UK after implementation of the advertising ban. Declines in awareness were greater in those channels regulated by the new law and change in awareness of tobacco promotions was much greater in the UK than the other three countries not affected by the ban. At least in the short term, there was no evidence that the law resulted in greater exposure to tobacco promotions in the few media channels not covered by the law. Notwithstanding the apparent success of the UK advertising ban and the controls in other countries, 9-22% of smokers in the four countries still reported noticing things that promoted smoking "often or very often" at Wave 2. The UK policy to ban tobacco advertising and promotion has significantly reduced exposure to pro-tobacco marketing influences. These findings support the effectiveness of comprehensive bans on advertising and promotion, as included in the Framework Convention on Tobacco Control.

The Impact of Smoking Bans on Smoking and Consumer Behavior: Quasi-Experimental Evidence from Switzerland.

In this paper, we exploit the progressive implementation of smoking bans in public venues at the state level in Switzerland to evaluate both the direct effects on smoking and the potential unintended consequences of these legislations on consumer behaviors as measured by visiting restaurants/bars and discos ('going out'). Our results indicate that public venue smoking bans in Switzerland reduce smoking rates, but the findings do not emerge until 1 year following the ban. This pattern of results is consistent with delays in ban enforcement on the part of business owners, difficulties in changing addictive behaviors such as smoking, and/or learning on the part of smokers. We find evidence that smoking bans influence going-out behavior and there is substantial heterogeneity across venue and consumer characteristics. Copyright © 2014 John Wiley & Sons, Ltd.

The Association between Point-of-Sale Advertising Bans and Youth Experimental Smoking: Findings from the Global Youth Tobacco Survey (GYTS).

PubMed

Shang, Ce; Huang, Jidong; Li, Qing; Chaloupka, Frank J

while existing research has demonstrated a positive association between exposure to point-of-sale (POS) tobacco advertising and youth smoking, there is limited evidence on the relationship between POS advertising restrictions and experimental smoking among youth. This study aims to fill this research gap by analyzing the association between POS advertising bans and youths' experimental smoking. Global Youth Tobacco Surveys from 130 countries during 2007-2011 were linked to the WHO "MPOWER" tobacco control policy measures to analyze the association between POS advertising bans (a dichotomous measure of the existence of such bans) and experimental smoking using weighted logistic regressions. All analyses were clustered at the country level and controlled for age, parents' smoking status, GDP per capita, and country-level tobacco control scores in monitoring tobacco use, protecting people from smoke, offering help to quit, warning about the dangers of tobacco, enforcing promotion/advertising bans, and raising taxes on tobacco. The results suggest that a POS advertising ban is significantly associated with reduced experimental smoking among youth (OR = 0.63, p < 0.01), and that this association is seen for both genders (boys OR = 0.74, p < 0.1; girls OR = 0.52, p < 0.001). POS advertising bans are significantly associated with reduced experimental smoking among youth. Adopting POS advertising bans has the potential to reduce tobacco use among their youth in countries currently without such bans.

Hospitality workers are a population particularly at risk from the noxious effects of environmental tobacco smoke (ETS). The Canton of Vaud, Switzerland banned smoking in public places in September 2009. This prospective study addresses the impact of the ban on the health of hospitality workers. ETS exposure was evaluated using a passive sampling device that measures airborne nicotine; lung function was assessed by spirometry; health-related quality of life, ETS exposure symptoms and satisfaction were measured by questionnaire. 105 participants (smokers and non-smokers) were recruited initially and 66 were followed up after one year. ETS exposure was significantly lower after the ban. Hospitality workers had lower pre-ban forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) values than expected. FEV1 remained stable after the ban, with a near-significant increase in the subgroup of asthmatics only. FVC increased at one year follow-up from 90.42% to 93.05% (p = 0.02) in the entire cohort; women, non-smokers and older participants gained the greatest benefit. The health survey showed an increase in physical wellbeing after the ban, the greatest benefit being observed in non-smokers. ETS exposure symptoms were less frequent after the ban, especially red and irritated eyes and sneezing. The new law was judged useful and satisfactory by the vast majority of employees, including smokers. The recent cantonal ban on smoking in public places brought about an improvement in lung function, physical well-being and ETS symptoms of hospitality workers, including smokers.

In October, 2008, legislation was implemented in the city and county of San Francisco, California, prohibiting the sale of tobacco products in pharmacies. To characterise public awareness and perceptions of the ban on tobacco sales in San Francisco community pharmacies. A brief, anonymous survey was used to assess public awareness and perceptions of a ban on tobacco sales approximately 1 year after implementation. Individuals were approached by researchers outside of chain pharmacies in San Francisco. Smokers and non-smokers were included, and participants did not have to be patrons of the pharmacy. Of 198 participants, 56% were in favor of the ban, 27% opposed it and 17% were undecided. A greater proportion of current tobacco users (81%) than former/never users (48%) were aware of the ban (p<0.001), and a lesser proportion were supportive of the ban (21% of current users vs 66% of former/never users; p<0.001). Most current tobacco users (88% of n=43) had not considered quitting smoking as a result of the ban. The majority of consumers indicated that the ban on cigarette sales did not influence their shopping behaviour at retail pharmacies. In the city and county of San Francisco, public support exists for prohibiting the sale of tobacco products in pharmacies.

Implementation of a workplace smoking ban in bars: the limits of local discretion.

PubMed

Montini, Theresa; Bero, Lisa A

2008-12-08

In January 1998, the California state legislature extended a workplace smoking ban to bars. The purpose of this study was to explore the conditions that facilitate or hinder compliance with a smoking ban in bars. We studied the implementation of the smoking ban in bars by interviewing three sets of policy participants: bar employers responsible for complying with the law; local government officials responsible for enforcing the law; and tobacco control activists who facilitated implementation. We transcribed the interviews and did a qualitative analysis of the text. The conditions that facilitated bar owners' compliance with a smoking ban in bars included: if the cost to comply was minimal; if the bars with which they were in competition were in compliance with the smoking ban; and if there was authoritative, consistent, coordinated, and uniform enforcement. Conversely, the conditions that hindered compliance included: if the law had minimal sanctions; if competing bars in the area allowed smoking; and if enforcement was delayed or inadequate. Many local enforcers wished to forfeit their local discretion and believed the workplace smoking ban in bars would be best implemented by a state agency. The potential implication of this study is that, given the complex nature of local politics, smoking bans in bars are best implemented at a broader provincial or national level.

Along with the introduction of a smoking ban in restaurants in 2004, respiratory symptoms, urinary cotinine and lung function among employees in 13 different bars and restaurants were studied before and after the ban came into force. At the same time measurements of air quality were taken at the respective restaurants and bars. The purpose of this study was to compare self-respiratory symptoms before and after the smoking ban among the staff at the establishments. The study included 93 men and women. These were followed during a work-shift before the smoking ban and three to eight months later. Initially 86 of the participants answered a questionnaire about respiratory tract symptoms , while 67 did so at follow-up. Before the ban 39 of the subjects (45.3%) reported wheezing in the chest and 28 (32.6%) said they had recently had an upper respiratory tract infection. 43.3% of the participants reported fewer symptoms and 20.9% more symptoms after the ban, while 35.8% reported no change. The corresponding figures among smokers were 47.5%, 15.0% and 37.5%. This study shows that the introduction of a smoking ban in restaurants contributes to a reduction in reported respiratory symptoms among employees, and may therefore be advantageous for the health of this group.

The Case for a Global Ban on Asbestos

Background All forms of asbestos are now banned in 52 countries. Safer products have replaced many materials that once were made with it. Nonetheless, many countries still use, import, and export asbestos and asbestos-containing products, and in those that have banned other forms of asbestos, the so-called “controlled use” of chrysotile asbestos is often exempted from the ban. In fact, chrysotile has accounted for > 95% of all the asbestos used globally. Objective We examined and evaluated the literature used to support the exemption of chrysotile asbestos from the ban and how its exemption reflects the political and economic influence of the asbestos mining and manufacturing industry. Discussion All forms of asbestos, including chrysotile, are proven human carcinogens. All forms cause malignant mesothelioma and lung and laryngeal cancers, and may cause ovarian, gastrointestinal, and other cancers. No exposure to asbestos is without risk. Illnesses and deaths from asbestos exposure are entirely preventable. Conclusions All countries of the world have an obligation to their citizens to join in the international endeavor to ban the mining, manufacture, and use of all forms of asbestos. An international ban is urgently needed. There is no medical or scientific basis to exempt chrysotile from the worldwide ban of asbestos. PMID:20601329

Alcohol advertising bans and alcohol abuse.

PubMed

Young, D J

1993-07-01

Henry Saffer [Saffer (1991) Journal of Health Economics 10, 65-79] concludes that bans on broadcast advertising for alcoholic beverages reduce total alcohol consumption, motor vehicle fatalities, and cirrhosis deaths. A reexamination of his data and procedures reveals a number of flaws. First, there is evidence of reverse causation: countries with low consumption/death rates tend to adopt advertising bans, creating a (spurious) negative correlation between bans and consumption/death rates. Second, even this correlation largely disappears when the estimates are corrected for serial correlation. Third, estimates based on the components of consumption--spirits, beer and wine--mostly indicate that bans are associated with increased consumption.

The aim of this survey was to explore staff attitudes to the indoor smoking ban in a medium secure unit and to ascertain if they had experienced any difficulties in imposing the ban in the four months after its introduction. All staff members available on duty who agreed to participate in the survey were interviewed using a semi-structured questionnaire. The response rate was 65%. Sixty-four percent of the staff supported the smoking ban. Forty-three percent reported experiencing patient management problems with the majority complaining of increased patient aggression, increased use of staff time in supervising patients smoking. Additionally, supervising staff were still being exposed to passive smoking. Sixty-five percent reported positive effects due to the ban with the majority reporting that patients were sleeping at night due to the smoking area being closed at night. A significant proportion of the staff is still opposed to the smoking ban. Changing staff attitudes through educational programmes will be important in ensuring success of a possible future total ban in psychiatric units. 2009 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Independent and Interactive Effects of Smoking Bans and Tobacco Taxes on a Cohort of US Young Adults.

PubMed

Vuolo, Mike; Kelly, Brian C; Kadowaki, Joy

2016-02-01

We examined the mutual effects of smoking bans and taxes on smoking among a longitudinal cohort of young adults. We combined a repository of US tobacco policies at the state and local level with the nationally representative geocoded National Longitudinal Survey of Youth 1997 (2004-2011) from ages 19 to 31 years and Census data, to examine the impact of tobacco policies on any current and daily pack smoking. The analytic sample amounts to 19,668 observations among 4341 individuals within 487 cities. For current smoking, we found significant effects for comprehensive smoking bans, but not excise taxes. We also found an interaction effect, with bans being most effective in locales with no or low taxes. For daily pack smoking, we found significant effects for taxes, but limited support for bans. Social smoking among young adults is primarily inhibited by smoking bans, but excise taxes only deter such smoking in the absence of a ban. Heavy smokers are primarily deterred by taxes. Although both policies have an impact on young adult smoking behaviors, their dual presence does not intensify each policy's efficacy.

The Italian smoking ban entered into force on January 10th, 2005, and banned smoking from enclosed workplaces and hospitality premises (HPs), even though provided separated smoking areas. Actually, only 1-2%of HPs built these areas, while no figures are available on the prevalence of smoking rooms in workplaces other than HPs. Italians were more in favour of the law after the ban. In 2008 Italians were the Europeans most in favour of a national smoking ban (88%). Measurements of environmental nicotine and particulate matter with a diameter <2.5 μm (PM2.5) collected in some Italian towns before and after 1-2 years from the implementation of the ban, recorded a 60-97%reduction. Second-hand smoke exposure decreased at home. After the ban, the highest exposures were recorded in some discos. In outdoor areas of HPs, covered in winter, second-hand smoke (SHS) exposure was similar to that recorded before the ban in enclosed areas. Enforcement controls carried out in 2005-2009 showed the compliance was good: out of 20,550 controls, in only about 2%of cases people were smoking.Whereas 80-90%of interviews in national surveys reported the ban was respected in HPs, only 70% said the same for workplaces. Controls in HPs and workplaces should become routine activity for technicians of National Health System Prevention Departments. Cigarette consumption decreased annually by 2% in 2004- 2010 (from 98.9 to 87 millions of kilos), and smoking prevalence annually decreased by 1-3% in men and by 0.4-2.0% in women. In 2005, cigarette consumption decreased by 6.2% and 3.5% of this reduction was attributable to the introduction of the ban. In 2005 medicinal nicotine sales increased by 69%. Out of 5 studies on reduction of acute myocardial infarction after the ban, four recorded a 11-13% reduction in persons aged <60 years. Despite the protests of hospitality sector against the ban in 2004, no studies on impact of the ban on hospitality industry businesses were conducted in Italy. We used the conceptual model for the evaluation of the impact of smoke-free policies, proposed by the International Agency for Research on Cancer (IARC), to compare Italian and Scottish evaluations of the bans. The Scottish evaluation was planned some years before the implementation, and was based on a network of researchers of different disciplines. The quantification of decrease in second-hand smoke (SHS) exposure in the general population and in hospitality workers was one of the main objectives of the Scottish evaluation. The Italian evaluation devoted more attention to distal (reduction of hospital admissions) and incidental effects of the law (trend in smoking prevalence, cigarette consumption). Qualitative studies in bars, homes, and communities recording changes in attitudes on tobacco smoking after the introduction of the ban, were conducted only in Scotland. In Italy the main problem was to develop and fund a network of researchers involved on a shared evaluation plan.

The role of secondary metabolites in the determination of cell identity has been an area of particular interest over recent years, and studies strongly indicate a connection between cell fate and the regulation of enzymes involved in secondary metabolism. In Arabidopsis thaliana, the maternally derived seed coat plays pivotal roles in both the protection of the developing embryo and the first steps of germination. In this regard, a characteristic feature of seed coat development is the accumulation of proanthocyanidins (PAs - a class of phenylpropanoid metabolites) in the innermost layer of the seed coat. Our genome-wide transcriptomic analysis suggests that the ovule identity factor SEEDSTICK (STK) is involved in the regulation of several metabolic processes, providing a strong basis for a connection between cell fate determination, development and metabolism. Using phenotypic, genetic, biochemical and transcriptomic approaches, we have focused specifically on the role of STK in PA biosynthesis. Our results indicate that STK exerts its effect by direct regulation of the gene encoding BANYULS/ANTHOCYANIDIN REDUCTASE (BAN/ANR), which converts anthocyanidins into their corresponding 2,3-cis-flavan-3-ols. Our study also demonstrates that the levels of H3K9ac chromatin modification directly correlate with the active state of BAN in an STK-dependent way. This is consistent with the idea that MADS-domain proteins control the expression of their target genes through the modification of chromatin states. STK might thus recruit or regulate histone modifying factors to control their activity. In addition, we show that STK is able to regulate other BAN regulators. Our study demonstrates for the first time how a floral homeotic gene controls tissue identity through the regulation of a wide range of processes including the accumulation of secondary metabolites.

2017-10-20

This paper aims to examine the process through which a total ban on asbestos was achieved in Japan. We reconstructed the process, analyzed the roles of involved parties/events, and drew lessons from the Japanese experience of achieving the ban. In Japan, a bill to phase out asbestos was proposed in 1992 but rejected without deliberation. Wide support for such a ban subsequently grew, however, largely due to the actions of trade unions and civil societies in establishing a coalition, raising awareness, organizing asbestos victims and their families, and propagating information on international developments. A governmental decision towards a ban was made in 2002 based on several national and international factors. A huge asbestos scandal in 2005 preponed the achievement of a total ban and led to the establishment of comprehensive measures to tackle asbestos issues. However, challenges remain for the elimination of asbestos-related diseases.

The aim of this study was to examine the effect of a smoking ban on lung function, fractional exhaled nitric oxide, and respiratory symptoms in nonsmoking hospitality workers. Secondhand smoke exposure at the workplace, spirometry, and fractional exhaled nitric oxide were measured in 92 nonsmoking hospitality workers before as well as twice after a smoking ban. At baseline, secondhand smoke-exposed hospitality workers had lung function values significantly below the population average. After the smoking ban, the covariate-adjusted odds ratio for cough was 0.59 (95% confidence interval, 0.36 to 0.93) and for chronic bronchitis 0.75 (95% confidence interval, 0.55 to 1.02) compared with the preban period. The below-average lung function before the smoking ban indicates chronic damages from long-term exposure. Respiratory symptoms such as cough decreased within 12 months after the ban.

Point-of-sale tobacco advertising in Beirut, Lebanon following a national advertising ban

PubMed Central

2013-01-01

Background The objective of this study was to conduct an audit of point-of-sale (POS) tobacco advertising and assess compliance with an advertising ban in a large district of Beirut, Lebanon. Methods The audit was conducted 3 months following the ban on tobacco advertising. Trained students observed all tobacco retail outlets (n = 100) and entered data into a web-based form using iPad® technology. Presence of tobacco advertisements was assessed to determine compliance with the national advertising ban. Results Among the 100 tobacco retail outlets, 62% had tobacco advertisements, including 7% with a tobacco brand logo as part of the main exterior store sign. Conclusions POS tobacco advertising is widespread in Beirut despite the national advertising ban. These findings point to an urgent need for the enforcement of the advertisement ban with tobacco retail outlets in Lebanon. PMID:23731766

In the first year after implementation of a public smoking ban a significant decrease in the incidence of acute myocardial infarction (AMI) was observed in Graubünden. In the present study we analyzed the incidence of AMI in the second year of the ban. In addition, we investigated the contribution of smoking ban-unrelated factors to the reduced incidence of AMI incidence observed after enactment of the ban. Data of all AMI patients who underwent coronary angiography at the Kantonsspital Graubünden, the only tertiary care hospital with a cardiac catheterization laboratory in Graubünden, between March 1st, 2009 and February 28th, 2010 were collected prospectively. Data were compared with those of the three preceding 12-month periods. We also estimated AMI incidence during the corresponding time period in Lucerne, a region with no smoke-free legislation, using data of the AMIS Plus registry. The influence of outdoor air pollution was analyzed with the help of official measurements of PM(10)- and NO(2)-concentrations in Graubünden. The prescription of lipid-lowering drugs was estimated by using sales figures in Graubünden and Lucerne. In Graubünden, the number of patients with AMI in the second year after adoption of the smoking ban was similar to that in the first year of the ban (188 vs. 183; P = ns) and significantly lower than in each of the two years preceding the ban (229 and 242, respectively; P <0.05 vs. each of the 12-month periods after the ban). Overall, the number of AMI patients in the two post-ban years was 21% lower than in the two pre-ban years. The reduction in the number of patients with AMI was most pronounced in non-smokers and individuals with known coronary artery disease. During the corresponding time period, no similar decrease in the incidence of AMI was observed in Lucerne. No association was found between the magnitude of outdoor air pollution and the incidence of AMI. During the observation period, the use of lipid-lowering drugs increased similarly in Graubünden and Lucerne. Compared with the two years preceding the implementation of a smoking ban, the incidence of AMI remained significantly reduced in the second year of the ban in Graubünden, whereas no similar reduction was seen in a comparable area without smoke-free legislation. Changes in outdoor air pollution or the use of lipid-lowering drugs did not substantially contribute to the decrease in the incidence of AMI that occurred after adoption of the ban in Graubünden.

Replacements for Trans Fats—Will There Be an Oil Shortage?

PubMed Central

Klonoff, David C.

2007-01-01

Manufacturers use the process of hydrogenation to create trans fats in order to increase the shelf life of baked and fried foods. Ingestion of trans fats is associated with an increased risk of cardiovascular disease. A groundswell of public sentiment is causing regulatory bodies to ban the use of trans fats in foods. Alternatives to trans fats are needed now in order to preserve the freshness and provide an appealing texture of many packaged foods. As trans fats become phased out, there are eight types of approaches currently being developed to substitute for these fats as ingredients for baked and fried foods: (1) modified hydrogenation, (2) genetically modified seeds, (3) interesterification, (4) fractionation and blending, (5) butter and animal fat, (6) natural saturated oils, (7) natural unsaturated oils, and (8) fat substitutes. These alternatives to trans fats will require close scrutiny to ascertain whether they will also turn out to be linked with cardiovascular disease. PMID:19885099

To evaluate retailer's compliance and consumer's perceptions of and experiences with the point-of-sale (POS) tobacco display ban in Norway, implemented 1 January 2010. Retailer compliance was measured using audit surveys. Consumer's perceptions of the ban were assessed in three web surveys: one conducted before and two after implementation of the ban. The sample for each of these consisted of about 900 people aged 15-54 years and an extra sample of smokers and snus users. 10 focus group interviews with male and female daily, occasional and former smokers aged 16-50 years (N=62) were also conducted, before and after implementation of the ban. Immediately following implementation of the POS display ban, compliance was 97% for cigarettes and rolling tobacco and 98% for snus. Preimplementation, young people were tempted by tobacco products when seeing them in the shop more often than older people. Postimplementation, young people also more often found it difficult to choose brand. The POS tobacco display ban was supported by a majority of the population, and by one out of three daily smokers. The removal of POS tobacco displays was perceived as a barrier for young people's access to tobacco products, as affecting attachment to cigarette brands and as contributing to tobacco denormalisation. Retailer's compliance with the POS display ban in Norway was high, and the ban was well supported in the population. Consumers believed that the ban could contribute to preventing smoking initiation among young people and to some extent also support cessation efforts.

Australian states have introduced an outright ban on commercial artificial tanning sunbeds. This was based on evidence from systematic reviews affirming a strong association between tanning bed use and increased risk of melanoma. The implementation of the ban provides an opportunity to assess the effectiveness of the legislation in preventing access to artificial UV radiation. Compliance with the ban has been enforced and monitored by government departments. We additionally monitored online tanning bed advertisements before and after the ban, showing a decline over time in the number of sunbeds advertised for sale on gumtree.com.au and ebay.com.au, from a peak of 115 advertisements in May 2014 to 50 or fewer per month from February 2015. There was also an increase in advertised price, with the percentage of sunbeds offered in Victoria on gumtree.com.au at higher than $2 000 increasing from around 25% between January and June 2014 to 65% in the quarter following the introduction of the ban. Advertisements on gumtree.com.au from individuals wishing to access a sunbed in a private home in Victoria increased from only isolated instances in the months immediately prior to the ban, to between 25 and 77 advertisements per month in the quarter following the ban. In summary, the introduction of an outright ban of commercial sunbeds has achieved a dramatic reduction in the availability of harmful artificial UV radiation sources in Australia. Long-term benefits to the health of the population and a reduction in costs to the health system are expected to result. © 2016 British Association of Dermatologists.

Comprehensive smoke-free policy in the alcohol and other drug (AOD) setting provides an opportunity to reduce tobacco related harms among clients and staff. This study aimed to examine within AOD services: staff awareness of their service's smoking policy compared to the written policy document and staff and service factors associated with accurate awareness of a total ban and perceived enforcement of a total ban. An audit of written tobacco smoking policy documents and an online cross-sectional survey of staff from 31 Australian AOD services. In addition, a contact at each service was interviewed to gather service-related data. Overall, 506 staff participated in the survey (response rate: 57%). Nearly half (46%) perceived their service had a total ban with 54% indicating that this policy was always enforced. Over one-third (37%) reported a partial ban with 48% indicating that this policy was always enforced. The audit of written policies revealed that 19 (61%) services had total bans, 11 (36%) had partial bans and 1 (3%) did not have a written smoking policy. Agreement between staff policy awareness and their service's written policy was moderate (Kappa 0.48) for a total ban and fair (Kappa 0.38) for a partial ban. Age (1 year increase) of staff was associated with higher odds of correctly identifying a total ban at their service. Tobacco smoking within Australian AOD services is mostly regulated by a written policy document. Staff policy awareness was modest and perceived policy enforcement was poor.

In Korea, registration of paraquat-containing herbicides was canceled in November 2011, and sales thereof were completely banned in November 2012. We evaluated the effect of the paraquat ban on the epidemiology and mortality of herbicide-induced poisoning. This retrospective study analyzed patients treated for herbicide poisoning at 17 emergency departments in South Korea between January 2010 and December 2014. The overall and paraquat mortality rates were compared pre- and post-ban. Factors associated with herbicide mortality were evaluated using logistic analysis. To determine if there were any changes in the mortality rates before and after the paraquat sales ban and the time point of any such significant changes in mortality, R software, version 3.0.3 (package, bcp) was used to perform a Bayesian change point analysis. We enrolled 2257 patients treated for herbicide poisoning (paraquat=46.8%). The overall and paraquat poisoning mortality rates were 40.6% and 73.0%, respectively. The decreased paraquat poisoning mortality rate (before, 75% vs. after, 67%, p=0.014) might be associated with increased intentionality. The multivariable logistic analysis revealed the paraquat ban as an independent predictor that decreased herbicide poisoning mortality (p=0.035). There were two major change points in herbicide mortality rates, approximately 3 months after the initial paraquat ban and 1 year after complete sales ban. This study suggests that the paraquat ban decreased intentional herbicide ingestion and contributed to lowering herbicide poisoning-associated mortality. The change point analysis suggests a certain timeframe was required for the manifestation of regulatory measures outcomes. © Copyright: Yonsei University College of Medicine 2017

The Impact of a City-Wide Indoor Smoking Ban on Smoking and Drinking Behaviors Across Emerging Adulthood

Talley, Anna E.; Fromme, Kim

2016-01-01

Introduction: Almost one-third of college students report recent cigarette use, primarily as “social smoking,” and often in conjunction with alcohol use. While city-wide indoor smoking bans effectively reduce the number of social opportunities to smoke (eg, bars and music clubs), little is known about how these bans may impact the smoking behaviors of college students. Furthermore, nothing is known about how indoor smoking bans may impact students’ drinking behaviors. The current study aims to determine the impact of a city-wide comprehensive indoor smoking ban on smoking and alcohol behaviors among a longitudinal sample of emerging adults. Methods: Data are from a 6-year longitudinal study (10 waves of data collection) that began the summer before college enrollment. Participants (N = 2244; 60% female) reported on their past 3-month smoking and drinking behaviors using Internet-based surveys at each wave. Piecewise linear growth modeling was used to determine how a city-wide comprehensive indoor smoking ban (implemented in the Fall of 2005 between Waves 4 and 5) impacted smoking frequency, cigarette quantity, drinking frequency, and number of binge drinking episodes. Results: Smoking and alcohol use increased from the summer before college through the semester before implementation of the city-wide smoking ban. While smoking frequency (P < .001) and cigarette quantity (P < .05) declined after the ban, drinking frequency increased (P < .001) and the number of binge drinking episodes remained stable. Conclusions: Current findings suggest that comprehensive indoor smoking bans can influence the smoking behaviors of emerging adults, whereas trajectories of drinking are relatively unchanged.

(1) Background: The home environment is a major source of Environmental Tobacco Smoke (ETS) exposure among children especially in early childhood. ETS exposure is an important health risk among children and can cause severe and chronic diseases, such as asthma, bronchitis, and premature death. However, ETS exposure at home has often been neglected in the Chinese families. Identification of factors that facilitate or otherwise hamper the adoption of home smoking ban will help in the design and implementation of evidence-based intervention programs. This study identifies factors correlated with home smoking bans in Chinese families with children. (2) Methods: A cross-sectional survey of parents living in Nanning city, Guangxi Province, China with at least one smoker and a child in the household was conducted between September, 2013 and January, 2014. A Chi-square test was used to compare categorical variables differences between the parents who had home smoking bans and those with no home smoking ban. Multiple logistic regression analyses were used to identify factors correlated with home smoking bans. (3) Results: 969 completed questionnaires were collected with a response rate of 92.29% (969/1050). Of the respondents (n = 969), 14.34% had complete home smoking bans. Factors that were associated with home smoking bans were: having no other smokers in the family (OR = 2.173), attaining education up to high school (OR = 2.471), believing that paternal smoking would increase the risk of lower respiratory tract illnesses (OR = 2.755), perceiving the fact that smoking cigarettes in the presence of the child will hurt the child’s health (OR = 1.547), believing that adopting a no smoking policy at home is very important (OR = 2.816), and being confident to prevent others to smoke at home (OR = 1.950). Additionally, parents who perceived difficulty in adopting a no smoking policy at home would not have a home smoking ban (OR = 0.523). (4) Conclusions: A home smoking ban is not widely adopted by families of hospitalized children in Guangxi Province, China. To protect the health of children, there is a need to develop and test interventions to promote home smoking bans. Factors identified as predictors of home smoking ban should be considered in the design of interventions. PMID:26821038

Prison staff and prisoner views on a prison smoking ban: evidence from the Tobacco in Prisons Study.

2018-05-15

In jurisdictions permitting prisoner smoking, rates are high (c75%), with smoking embedded in prison culture, leading to secondhand smoke exposures among staff and prisoners and challenges for smoking cessation. Momentum is building to ban smoking in prisons, but research on staff and prisoner views is lacking. We address this gap, providing evidence on staff and prisoner views throughout all Scottish prisons. Data were collected prior to announcement of a (November 2018) prison smoking ban throughout Scotland. Mixed methods were used: surveys of staff (online, N=1,271, ~27%) and prisoners (questionnaire, N=2,512, ~34%); 17 focus groups and two paired interviews with staff in 14 prisons. Staff were more positive than prisoners about bans and increased smoking restrictions, although prisoner views were more favourable should e-cigarettes be permitted. Non-smokers were more positive than smokers. Whilst 74% staff and 22% prisoners agreed bans were a good idea, both groups acknowledged implementation and enforcement challenges. Staff views were influenced by beliefs about: acceptability of the policy in principle; and whether/how bans could be achieved. Although some voiced doubts about smoke-free policies, staff likened a ban to other operational challenges. Staff raised concerns around needs for appropriate measures, resources and support, adequate lead-in time, and effective communication prior to a ban. We recommend that regular and open opportunities for dialogue within and between different stakeholder groups are created when preparing for prison smoking bans, and that specific measures to address staff and prisoner concerns are incorporated into plans to create and maintain smoke-free environments. To our knowledge, this study is the first to research staff and prisoner views across a whole prison system prior to implementation of smoke-free policies. The results highlight potential challenges and suggest measures which might help to maximise the success of bans. Our results are relevant for prison service managers responsible for the forthcoming introduction of a ban in Scottish prisons (November 2018) and for other prison systems and comparable institutions planning smoke-free initiatives. Given that prison smoking bans may be contentious, we recommend creating regular and open opportunities for dialogue between stakeholders when preparing for and maintaining smoke-free environments.

Implementation of a workplace smoking ban in bars: The limits of local discretion

PubMed Central

Montini, Theresa; Bero, Lisa A

2008-01-01

Background In January 1998, the California state legislature extended a workplace smoking ban to bars. The purpose of this study was to explore the conditions that facilitate or hinder compliance with a smoking ban in bars. Methods We studied the implementation of the smoking ban in bars by interviewing three sets of policy participants: bar employers responsible for complying with the law; local government officials responsible for enforcing the law; and tobacco control activists who facilitated implementation. We transcribed the interviews and did a qualitative analysis of the text. Results The conditions that facilitated bar owners' compliance with a smoking ban in bars included: if the cost to comply was minimal; if the bars with which they were in competition were in compliance with the smoking ban; and if there was authoritative, consistent, coordinated, and uniform enforcement. Conversely, the conditions that hindered compliance included: if the law had minimal sanctions; if competing bars in the area allowed smoking; and if enforcement was delayed or inadequate. Conclusion Many local enforcers wished to forfeit their local discretion and believed the workplace smoking ban in bars would be best implemented by a state agency. The potential implication of this study is that, given the complex nature of local politics, smoking bans in bars are best implemented at a broader provincial or national level. PMID:19063716

Reductions in cardiovascular, cerebrovascular, and respiratory mortality following the national irish smoking ban: interrupted time-series analysis.

Previous studies have shown decreases in cardiovascular mortality following the implementation of comprehensive smoking bans. It is not known whether cerebrovascular or respiratory mortality decreases post-ban. On March 29, 2004, the Republic of Ireland became the first country in the world to implement a national workplace smoking ban. The aim of this study was to assess the effect of this policy on all-cause and cause-specific, non-trauma mortality. A time-series epidemiologic assessment was conducted, utilizing Poisson regression to examine weekly age and gender-standardized rates for 215,878 non-trauma deaths in the Irish population, ages ≥35 years. The study period was from January 1, 2000, to December 31, 2007, with a post-ban follow-up of 3.75 years. All models were adjusted for time trend, season, influenza, and smoking prevalence. Following ban implementation, an immediate 13% decrease in all-cause mortality (RR: 0.87; 95% CI: 0.76-0.99), a 26% reduction in ischemic heart disease (IHD) (RR: 0.74; 95% CI: 0.63-0.88), a 32% reduction in stroke (RR: 0.68; 95% CI: 0.54-0.85), and a 38% reduction in chronic obstructive pulmonary disease (COPD) (RR: 0.62; 95% CI: 0.46-0.83) mortality was observed. Post-ban reductions in IHD, stroke, and COPD mortalities were seen in ages ≥65 years, but not in ages 35-64 years. COPD mortality reductions were found only in females (RR: 0.47; 95% CI: 0.32-0.70). Post-ban annual trend reductions were not detected for any smoking-related causes of death. Unadjusted estimates indicate that 3,726 (95% CI: 2,305-4,629) smoking-related deaths were likely prevented post-ban. Mortality decreases were primarily due to reductions in passive smoking. The national Irish smoking ban was associated with immediate reductions in early mortality. Importantly, post-ban risk differences did not change with a longer follow-up period. This study corroborates previous evidence for cardiovascular causes, and is the first to demonstrate reductions in cerebrovascular and respiratory causes.

Background Previous studies have shown decreases in cardiovascular mortality following the implementation of comprehensive smoking bans. It is not known whether cerebrovascular or respiratory mortality decreases post-ban. On March 29, 2004, the Republic of Ireland became the first country in the world to implement a national workplace smoking ban. The aim of this study was to assess the effect of this policy on all-cause and cause-specific, non-trauma mortality. Methods A time-series epidemiologic assessment was conducted, utilizing Poisson regression to examine weekly age and gender-standardized rates for 215,878 non-trauma deaths in the Irish population, ages ≥35 years. The study period was from January 1, 2000, to December 31, 2007, with a post-ban follow-up of 3.75 years. All models were adjusted for time trend, season, influenza, and smoking prevalence. Results Following ban implementation, an immediate 13% decrease in all-cause mortality (RR: 0.87; 95% CI: 0.76–0.99), a 26% reduction in ischemic heart disease (IHD) (RR: 0.74; 95% CI: 0.63–0.88), a 32% reduction in stroke (RR: 0.68; 95% CI: 0.54–0.85), and a 38% reduction in chronic obstructive pulmonary disease (COPD) (RR: 0.62; 95% CI: 0.46–0.83) mortality was observed. Post-ban reductions in IHD, stroke, and COPD mortalities were seen in ages ≥65 years, but not in ages 35–64 years. COPD mortality reductions were found only in females (RR: 0.47; 95% CI: 0.32–0.70). Post-ban annual trend reductions were not detected for any smoking-related causes of death. Unadjusted estimates indicate that 3,726 (95% CI: 2,305–4,629) smoking-related deaths were likely prevented post-ban. Mortality decreases were primarily due to reductions in passive smoking. Conclusions The national Irish smoking ban was associated with immediate reductions in early mortality. Importantly, post-ban risk differences did not change with a longer follow-up period.

Bane, Charles E.; Gailani, David

2014-01-01

Anticoagulants currently used in clinical practice to treat thromboembolic disorders are effective but increase the risk of severe bleeding because they target proteins that are essential for normal coagulation (hemostasis). Drugs with better safety profiles are required for prevention and treatment of thromboembolic disease. Coagulation factor XIa has emerged as a novel target for safer anticoagulant therapy because of its role in thrombosis and its relatively small contribution to hemostasis. PMID:24886766

The Korean government implemented a smoking ban at square floor area of ≥150 m(2), rather than <150 m(2), restaurants and pubs from July 2013. This study examined the effects of the smoking regulations in restaurants and pubs in terms of the air quality, biomarker levels and health effects on staff. Particulate matter smaller than 2.5 µm (PM2.5) was measured in 146 facilities before and 1 month after the ban. The urinary cotinine and 4-(methylnitrosamino)-1-(3-pyridyl)-1- butanol (NNAL) levels were measured in 101 staff members at 77 facilities before and 1 month after the ban. We also measured self-reported respiratory and sensory symptoms on both phases. Of the 146 facilities, 121 facilities were included in the PM2.5 analysis. In ≥150 m(2) pubs, the indoor PM2.5 concentration was significantly reduced after the ban (p < .05). While the urinary cotinine concentrations of the staff in all facilities were not changed after the ban, the total NNAL concentrations of the staff in ≥150 m(2) pubs were significantly reduced after the ban (p < .05). The health effects on staff show that only sensory symptoms significantly improved in ≥150 m(2) facilities after the ban (p < .05). The smoking ban significantly reduced the levels of PM2.5 and total NNAL concentrations in ≥150 m(2) pubs and improved sensory health among staff in ≥150 m(2) facilities. The results of this study can be useful in supporting an expansion of the smoking ban in all indoor places, including <150 m(2) restaurants and pubs. © The Author 2015.

Background In February 2003, a comprehensive ban on tobacco promotion came into effect in the United Kingdom, which prohibited tobacco marketing through print and broadcast media, billboards, the internet, direct mail, product placement, promotions, free gifts, coupons and sponsorships. Objective To investigate the impact of the UK's comprehensive ban on tobacco promotion on adult smokers' awareness of tobacco marketing in the UK relative to Canada, the United States and Australia. Design A total of 6762 adult smokers participated in two waves of a random digit dialled telephone survey across the four countries. Wave 1 was conducted before the UK ban (October–December 2002) and Wave 2 was conducted after the UK ban (May–September 2003). Key measures Awareness of a range of forms of tobacco marketing. Results Levels of tobacco promotion awareness declined significantly among smokers in the UK after implementation of the advertising ban. Declines in awareness were greater in those channels regulated by the new law and change in awareness of tobacco promotions was much greater in the UK than the other three countries not affected by the ban. At least in the short term, there was no evidence that the law resulted in greater exposure to tobacco promotions in the few media channels not covered by the law. Notwithstanding the apparent success of the UK advertising ban and the controls in other countries, 9–22% of smokers in the four countries still reported noticing things that promoted smoking “often or very often” at Wave 2. Conclusions The UK policy to ban tobacco advertising and promotion has significantly reduced exposure to pro‐tobacco marketing influences. These findings support the effectiveness of comprehensive bans on advertising and promotion, as included in the Framework Convention on Tobacco Control. PMID:16754943

Mechanical Systems Versus Smoking Bans for Secondhand Smoke Control

Introduction: Despite international efforts to implement smoking bans, several national legislations still allow smoking and recommend mechanical systems, such as ventilation and air extraction, to eliminate secondhand smoke (SHS) health-related risks. We aimed to quantify the relative contribution of mechanical systems and smoking bans to SHS elimination. Methods: A cross-sectional study was conducted in randomly selected establishments from 4 Mexican cities (3 with no ban). SHS exposure was assessed using nicotine passive monitors. Establishment characteristics, presence of mechanical systems, and enforcement of smoking policies were obtained through direct observation and self-report. Multilevel models were used to assess relative contributions to SHS reduction. Results: Compared with Mexico City, nicotine concentrations were 3.8 times higher in Colima, 5.4 in Cuernavaca, and 6.4 in Toluca. Mechanical systems were not associated with reduced nicotine concentrations. Concentration differences between cities were largely explained by the presence of smoking bans (69.1% difference reduction) but not by mechanical systems (−5.7% difference reduction). Conclusions: Smoking bans represent the only effective approach to reduce SHS. Tobacco control regulations should stop considering mechanical systems as advisable means for SHS reduction and opt for complete smoking bans in public places. PMID:21994338

Background and Purpose . The association between smoking and CV has been proved; however smoking is still the first preventable cause of death in the EU. We aim to evaluate the potential impact of the smoke ban on the number of ACS events in the Portuguese population. In addition, we evaluate the longitudinal effects of the smoking ban several years after its implementation. Methods . We analyzed the admission rate for ACS before and after the ban using data from hospital admission. Monthly crude rate was computed, using the Portuguese population as the denominator. Data concerning the proportion of smokers among ACS patients were obtained from the NRACS. Interrupted time series were used to assess changes over time. Results . A decline of -5.8% was found for ACS crude rate after the smoking ban. The decreasing trend was observed even after years since the law. The effect of the ban was higher in men and for people over 65 years. The most significant reduction of ACS rate was found in Lisbon. Conclusions . Our results suggest that smoking ban is related to a decline in ACS admissions, supporting the importance of smoke legislation as a public health measure, contributing to the reduction of ACS rate.

The purpose of this study was to measure students' attitudes towards a total smoking ban in schools and towards impositions in cases of violation. Cross-sectional survey of 1 738 students of 12 public schools in Schleswig-Holstein (grades 7-13, age 11-20 years). Data were collected by means of written questionnaires administered during class time. The following variables were assessed: attitude towards smoking ban, attitude towards impositions, age, sex, citizenship, perceived school climate, current smoking, lifetime smoking; for smokers, and additionally, the "Heaviness of Smoking Index". 76.5% of all students agreed with a total smoking ban, 66.4% agreed with the punishment of violations. Higher acceptance rates were found among girls, young students (11-15 years of age), for never-smokers, and for students who feel comfortable at school. Acceptance of the smoking ban is closely related to current smoking status: 93% of the non-smoking students, but only 14% of the daily smoking students agreed with the regulations. Refusal of the ban increased with increasing physical dependence. The intensification of the smoking ban in public schools meets approval by the majority of students. Smoking students should be more strongly involved in the implementation process, e.g., by supplemental cessation programmes.

Independent and Interactive Effects of Smoking Bans and Tobacco Taxes on a Cohort of US Young Adults

Objectives. We examined the mutual effects of smoking bans and taxes on smoking among a longitudinal cohort of young adults. Methods. We combined a repository of US tobacco policies at the state and local level with the nationally representative geocoded National Longitudinal Survey of Youth 1997 (2004–2011) from ages 19 to 31 years and Census data, to examine the impact of tobacco policies on any current and daily pack smoking. The analytic sample amounts to 19 668 observations among 4341 individuals within 487 cities. Results. For current smoking, we found significant effects for comprehensive smoking bans, but not excise taxes. We also found an interaction effect, with bans being most effective in locales with no or low taxes. For daily pack smoking, we found significant effects for taxes, but limited support for bans. Conclusions. Social smoking among young adults is primarily inhibited by smoking bans, but excise taxes only deter such smoking in the absence of a ban. Heavy smokers are primarily deterred by taxes. Although both policies have an impact on young adult smoking behaviors, their dual presence does not intensify each policy’s efficacy. PMID:26691133

Objectives. We assessed support for a ban by the Food and Drug Administration on menthol in cigarettes and behavioral intentions among menthol smokers in the event of such a ban. Methods. We surveyed 2649 never, former, and current smokers and used ordinal logistic regression to calculate weighted point estimates and predictors of support for a menthol ban among the adult population and menthol smokers only. For menthol smokers, we also calculated weighted point estimates and predictors of behavioral intentions. Results. Overall, 28.2% of adults opposed, 20.0% supported, and 51.9% lacked a strong opinion about a menthol ban. Support was highest among Hispanics (36.4%), African Americans (29.0%), never smokers (26.8%), and respondents with less than a high school education (28.8%). Nearly 40% of menthol smokers said they would quit if menthol cigarettes were no longer available, 12.5% would switch to a nonmenthol brand, and 25.2% would both switch and try to quit. Conclusions. Support for a menthol ban is strongest among populations with the highest prevalence of menthol cigarette use. A menthol ban might motivate many menthol smokers to quit. PMID:22994173

We assessed current home smoking behaviors and secondhand smoke (SHS) levels among parents of children in low-income, racial/ethnic minority communities in Massachusetts. We used a cross-sectional design to assess home smoking rules, smoking status, cigarettes smoked in the home, and barriers and benefits to attaining a smoke-free home among 138 caregivers (mean age=30.0 years; 92% women) of children aged 0 to 6 years, between April 2010 and September 2012. Indoor SHS was assessed using a nicotine dosimeter. Households with no ban reported a higher weekly mean number of cigarettes smoked in the home (114 cigarettes/week) than homes with partial (71 cigarettes/week) or complete (30 cigarettes/week) bans (P<.01). Smoking occurred outside more than inside homes with partial or complete bans. Air nicotine levels were positively associated with no household smoking ban, current smoking by the caregiver, and smoking indoors. Strategies to reduce home SHS should focus on a "complete" home smoking ban and smoking cessation. SHS mitigation strategies such as smoking outside were associated with lower SHS among participants unable to maintain a complete ban, and might enhance the likelihood of longer term success while immediately reducing home SHS.

Bans on the sale of tobacco products in pharmacies allow pharmacies to provide health information and services without the conflict of interest posed by concurrent tobacco sales. As health care providers, pharmacies are trusted sources of information for patients. The existence of tobacco products in pharmacies is contrary to their mission as a health care entity. By May 2012, a full 27 Massachusetts municipalities had banned the sale of tobacco products in health care institutions, including pharmacies. These bans covered 30% of the state's population.

Objective To analyze household smoking bans over time and predictors of bans among communities in the Dominican Republic, historically a significant tobacco-growing country with few tobacco control regulations. Methods Baseline (2004) and follow-up surveillance surveys (2006, 2007) (each n > 1 000 randomly selected households) conducted in six economically disadvantaged communities (three tobacco-growing and two each urban, peri-urban, and rural) assessed household members’ demographics, health status, and household characteristics, including smoking restrictions. Results Between 2004 and 2007, household smoking-ban prevalence increased in all communities (24%–45%). Households with smokers (versus those without) adopted bans at lower rates (6%–17%; 35%–58%). Logistic regression models demonstrated that allowing smoking in nonsmoking households was more likely in tobacco-growing communities, Catholic households, and those with a member with a cardiovascular problem. Having a child under age 5 or a member with a respiratory condition was not significantly related to establishing smoking bans. Conclusions Prevalence of households banning smoking increased in all communities but remained well below rates in industrialized countries. For low- and middle-income countries or those early in tobacco control, small awareness-raising measures (including surveillance activities) may lead to significant increases in household-ban adoption, particularly among nonsmoking households. Increasing household-ban prevalence may affect community norms that can lead to greater adoption. Having household members who smoke and being in a tobacco-growing community may mitigate the establishment of household bans. Increasing individuals’ knowledge about the far-reaching health effects of secondhand smoke exposure on children and nonsmoking adults (healthy or unhealthy) may help overcome these obstacles.

Smoke-free laws and direct democracy initiatives on smoking bans in Germany: a systematic review and quantitative assessment.

Kohler, Stefan; Minkner, Philipp

2014-01-03

Germany's 16 states regulate smoking differently within health protection principles laid down in the federal law. All state smoke-free laws in Germany have undergone at least one change since taking effect. We systematically review federal and state laws regulating smoking, as well as petitions, popular initiatives and referenda that aimed at changing statutory smoking bans. Data generated through the systematic review were correlated with state smoking rates. The protection from the dangers of secondhand smoke is the primary motive for smoking bans in Germany. The first smoke-free laws affecting smoking in pubs, restaurants and several other public places were introduced in 2007. In 2008, the Federal Constitutional Court of Germany ruled in a leading decision on the smoke-free laws of two states that some common smoking ban exemptions of the introduced smoke-free laws violate the basic right to freely exercise a profession and mandated revisions. All states but Bavaria and Saarland, whose smoking bans were more and less comprehensive than those judged by the constitutional court, respectively, needed to change the smoking ban exemptions to reconcile their smoke-free laws with the constitution. Direct democracy initiatives to change smoking bans were only successful in Bavaria in 2010, but a total of 15 initiatives by citizens' or interest groups attempted to influence non-smokers protection legislation through direct democratic procedures. Early ratification of a smoking ban in a federal state correlates with a higher reduction in the smoking rate from 2005 to 2009 (Spearman's ρ = 0.51, p = 0.04). The federal government structure and direct democratic participation in smoke-free legislation in Germany has produced a diversity of local smoking bans and exemptions.

Effects of Enactment of Legislative (Public) Smoking Bans on Voluntary Home Smoking Restrictions: A Review

PubMed Central

Arsenault, Nicole

2017-01-01

Introduction: The positive effects of worldwide increases in enactment of legislative bans on smoking in public areas have been well documented. Relatively little is known about the effects of such bans on voluntary home smoking behavior. Meanwhile, private spaces, such as homes, have replaced public spaces as the primary milieu of secondhand smoke exposure. Methods: A systematic search of peer-reviewed articles was conducted using multiple databases including Cochrane Library, Cinahl, Embase, Global Health, Health Star, Joanna Briggs, MEDLINE, PsycINFO, PAIS International, PubMed, and Web of Science. We examined peer-reviewed studies that considered the impact of legislation-based public smoking bans on enactment of private home smoking restrictions. Results: Sixteen articles published between 2002 and 2014 were identified and included. Our results suggest overall positive effects post-legislative ban with the majority of studies demonstrating significant increases in home smoking restrictions. Studies focusing on smoking and nonsmoking samples as well as child populations are discussed in depth. Conclusions: Existing evidence indicates an overall significant positive effect post-legislative ban on voluntary home smoking restrictions. While disentangling these effects over space and time remains a challenge, scientific research has converged in dispelling any notion of significant displacement of smoking into the home. Policy makers, especially those in countries without existing public smoking legislation, can rest assured that these types of bans contribute to the minimization of tobacco-related harm. Implications: Findings converge in dispelling notions of displacement of smoking into the home as a consequence of legislative bans that prohibit smoking in public spaces. Evidence from the studies reviewed suggests that through their influence on social norms, legislative bans on smoking in public places may encourage citizens to establish voluntary home smoking restrictions, thus decreasing harm related to secondhand smoke.

On January 1, 2008, the French government implemented a national ban on indoor smoking in hospitality venues. Survey results indicate the indoor ban has been successful at dramatically reducing indoor smoking; however, there are reports of an increased number of outdoor hospitality spaces (patios) where smoking can take place. This study sought to understand if the indoor ban simply moved smoking to the outdoors, and to assess levels of support for smoking restrictions in outdoor hospitality settings after the smoke-free law. Telephone interviews were conducted among 1067 adult smokers before and after the 2008 indoor ban as part of the International Tobacco Control (ITC) France Survey. Among other topics, this survey measures how the smoking ban has influenced smoking behaviour relevant to outdoor sections of hospitality venues. In addition, 414 non-smoking adults and 164 respondents who had quit smoking between waves were also asked about support for outdoor smoking restrictions. Reported smoking outdoors at cafés/pubs/bars increased from 33.6% of smokers at Wave 1 to 75.9% at Wave 2. At restaurants, smoking outdoors increased from 28.9% to 59.0%. There was also an increase in reported non-smoking for both visits to cafés/pubs/bars, and restaurants from 13.4% to 24.7%, and 30.4% to 40.8% respectively. The majority of smokers (74.5%), non-smokers (89.4%) and quitters (74.0%) support a partial or complete ban on smoking in outdoor areas of restaurants. The indoor smoking ban moved smoking to outdoor spaces; however, the ban is also associated with increased non-smoking behaviour. The majority of respondents support outdoor smoking restrictions in patio environments.

On January 11, 2009, a comprehensive smoking ban was implemented in Taiwan. The aim of this study was to evaluate the effect of this ban on hospital admissions for ischemic heart disease (IHD). Trends in the country-level monthly hospital admission rates for IHD were determined and frequency compared to other conditions such as control conditions cholecystitis, bowel obstruction, and appendicitis from January 1997 (1 year before the first phase of smoke-free laws was implemented) to December 2012 (3 years after the second phase of the ban). Poisson regression with a monthly time-series model was used to determine alterations in the trend of admission rates for IHD with comparison to rates of other disorders after the ban. Hospital admissions for IHD decreased by 0.8% (incidence rate ratio [RR]: 0.992; 95% confidence interval [CI] = 0.991-0.994) and 1.1% (incidence RR: 0.989; 95% CI = 0.988-0.991) following the first (September 19, 1997 to January 10, 2009) and second (January 11, 2009 to December 31, 2012) phases of the ban, respectively, compared with those prior to the pre-ban period, the corresponding values for the control conditions were 0.6% (95% CI = 0.5%-0.7%) and 0.7% (95% CI = 0.6%-0.9%). The admission rates significantly fell for both men and women and for all examined age categories after both first and second phases of the ban. The present findings provide evidence of a significant reduction in hospital admissions for IHD in Taiwan following smoking bans.

The Impact of a City-Wide Indoor Smoking Ban on Smoking and Drinking Behaviors Across Emerging Adulthood.

Almost one-third of college students report recent cigarette use, primarily as "social smoking," and often in conjunction with alcohol use. While city-wide indoor smoking bans effectively reduce the number of social opportunities to smoke (eg, bars and music clubs), little is known about how these bans may impact the smoking behaviors of college students. Furthermore, nothing is known about how indoor smoking bans may impact students' drinking behaviors. The current study aims to determine the impact of a city-wide comprehensive indoor smoking ban on smoking and alcohol behaviors among a longitudinal sample of emerging adults. Data are from a 6-year longitudinal study (10 waves of data collection) that began the summer before college enrollment. Participants (N = 2244; 60% female) reported on their past 3-month smoking and drinking behaviors using Internet-based surveys at each wave. Piecewise linear growth modeling was used to determine how a city-wide comprehensive indoor smoking ban (implemented in the Fall of 2005 between Waves 4 and 5) impacted smoking frequency, cigarette quantity, drinking frequency, and number of binge drinking episodes. Smoking and alcohol use increased from the summer before college through the semester before implementation of the city-wide smoking ban. While smoking frequency (P < .001) and cigarette quantity (P < .05) declined after the ban, drinking frequency increased (P < .001) and the number of binge drinking episodes remained stable. Current findings suggest that comprehensive indoor smoking bans can influence the smoking behaviors of emerging adults, whereas trajectories of drinking are relatively unchanged. © The Author 2015.

Hyogo is the second prefecture, after Kanagawa, to enact a smoking ban in public places in Japan. The effect of this smoking ban on acute coronary syndrome (ACS) has not been evaluated. Changes in the annual number of ACS hospital cases in Hyogo Prefecture, before and after the enactment of the prefectural legislative ban on smoking in public places, are to be compared with those in Gifu Prefecture, where there is no smoking-ban legislation. Consecutive Hyogo residents with ACS, admitted to 33 major hospitals in the Hanshin-Awaji-Kobe district, which covers 56% of the population, during the 12 months before implementation of the legislation (April 2012 through March 2013) and during the same 24 months thereafter (April 2013 through March 2015) will be enrolled. Consecutive patients with ACS, who are Gifu residents, treated at the 20 major hospitals in Gifu Prefecture will be enrolled as geographical controls. The primary endpoint is the change in number of ACS admissions from April 2012 through March 2015, considering the periods before and after the smoking-ban legislation in Hyogo prefecture. Our study has certain strengths: (1) This is the first large Japanese study of ACS registry with smoking-ban legislation. (2) Major hospitals in the Hanshin-Awaji-Kobe district are included. (3) The data will cover 3 years including 1 year before legislation enactment. (4) The data will be compared with those of Gifu Prefecture, where smoking-ban legislation will not be enacted. (5) The very large database makes possible analysis of subgroups based on age and gender. Copyright © 2013 Japanese College of Cardiology. Published by Elsevier Ltd. All rights reserved.

To describe the issues encountered during the implementation of an indoor smoking ban in prison and its effects on self-reported tobacco use, perceived exposure to second-hand smoke (SHS) and perceived health status of inmates in Quebec's provincial correctional facilities. Quantitative data were obtained from 113 inmates in three provincial correctional facilities in the province of Quebec, Canada. Qualitative data were obtained from 52 inmates and 27 staff members. Participants were recruited through a self-selection process. Particular efforts were made to enrol proportions of men, women, smokers and non-smokers similar to those generally found among correctional populations. Despite the indoor smoking ban, 93% of inmates who declared themselves smokers reported using tobacco products inside the correctional facilities and 48% did not report any reduction in their tobacco use. Only 46% of smokers declared having been caught smoking inside the facility, and more than half of them (58%) reported no disciplinary consequences to their smoking. A majority of inmates incarcerated before the implementation of the ban (66%) did not perceive a reduction of their exposure to SHS following the indoor ban. Enforcement issues were encountered during the implementation of the indoor ban, notably because of the amendment made to the original regulation (total smoking ban) and tolerance from smokers in the staff towards indoor smoking. They were also related to perceptions that banning indoor smoking is complex and poses management problems. This study's findings emphasize the importance of considering organizational and environmental factors when planning the implementation of an indoor smoking ban in correctional facilities.

In 2010 the government of the republic of Zambia stopped training traditional birth attendants and forbade them from conducting home deliveries as they were viewed as contributing to maternal mortality. This study explored positive and negative maternal health related experiences and effects of the ban in a rural district of Kazungula. This was a phenomenological study and data were collected through focus group discussions as well as in-depth interviews with trained traditional birth attendants (tTBAs) and key informant interviews with six female traditional leaders that were selected one from each of the six zones. All 22 trained tTBAs from three clinic catchment areas were included in the study. Content analysis was used to analyse the data after coding it using NVIVO 8 software. Home deliveries have continued despite the community and tTBAs being aware of the ban. The ban has had both negative and positive effects on the community. Positive effects include early detection and management of pregnancy complications, enhanced HIV/AIDS prevention and better management of post-natal conditions, reduced criticisms of tTBAs from the community in case of birth complications, and quick response at health facilities in case of an emergency. Negatives effects of the ban include increased work load on the part of health workers, high cost for lodging at health facilities and traveling to health facilities, as well as tTBAs feeling neglected, loss of respect and recognition by the community. Countries should design their approach to banning tTBAs differently depending on contextual factors. Further, it is important to consider adopting a step wise approach when implementing the ban as the process of banning tTBAs may trigger several negative effects.

This study examined tobacco smoke pollution (also known as thirdhand smoke, THS) in hotels with and without complete smoking bans and investigated whether non-smoking guests staying overnight in these hotels were exposed to tobacco smoke pollutants. A stratified random sample of hotels with (n=10) and without (n=30) complete smoking bans was examined. Surfaces and air were analysed for tobacco smoke pollutants (ie, nicotine and 3-ethynylpyridine, 3EP). Non-smoking confederates who stayed overnight in guestrooms provided urine and finger wipe samples to determine exposure to nicotine and the tobacco-specific carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone as measured by their metabolites cotinine and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), respectively. Compared with hotels with complete smoking bans, surface nicotine and air 3EP were elevated in non-smoking and smoking rooms of hotels that allowed smoking. Air nicotine levels in smoking rooms were significantly higher than those in non-smoking rooms of hotels with and without complete smoking bans. Hallway surfaces outside of smoking rooms also showed higher levels of nicotine than those outside of non-smoking rooms. Non-smoking confederates staying in hotels without complete smoking bans showed higher levels of finger nicotine and urine cotinine than those staying in hotels with complete smoking bans. Confederates showed significant elevations in urinary NNAL after staying in the 10 most polluted rooms. Partial smoking bans in hotels do not protect non-smoking guests from exposure to tobacco smoke and tobacco-specific carcinogens. Non-smokers are advised to stay in hotels with complete smoking bans. Existing policies exempting hotels from complete smoking bans are ineffective.

Background: On January 1, 2008, the French government implemented a national ban on indoor smoking in hospitality venues. Survey results indicate the indoor ban has been successful at dramatically reducing indoor smoking; however, there are reports of an increased number of outdoor hospitality spaces (patios) where smoking can take place. This study sought to understand if the indoor ban simply moved smoking to the outdoors, and to assess levels of support for smoking restrictions in outdoor hospitality settings after the smoke-free law. Methods: Telephone interviews were conducted among 1067 adult smokers before and after the 2008 indoor ban as part of the International Tobacco Control (ITC) France Survey. Among other topics, this survey measures how the smoking ban has influenced smoking behaviour relevant to outdoor sections of hospitality venues. In addition, 414 non-smoking adults and 164 respondents who had quit smoking between waves were also asked about support for outdoor smoking restrictions. Results: Reported smoking outdoors at cafés/pubs/bars increased from 33.6% of smokers at Wave 1 to 75.9% at Wave 2. At restaurants, smoking outdoors increased from 28.9% to 59.0%. There was also an increase in reported non-smoking for both visits to cafés/pubs/bars, and restaurants from 13.4% to 24.7%, and 30.4% to 40.8% respectively. The majority of smokers (74.5%), non-smokers (89.4%) and quitters (74.0%) support a partial or complete ban on smoking in outdoor areas of restaurants. Conclusion: The indoor smoking ban moved smoking to outdoor spaces; however, the ban is also associated with increased non-smoking behaviour. The majority of respondents support outdoor smoking restrictions in patio environments. PMID:22294782

Birth outcomes are relevant for future children's heath. Capitalising on a natural experimental design in Switzerland, we evaluated how regional smoking bans introduced at different time points affected birth outcomes, including preterm and early-term births. We used birth registry data of all singleton neonates born in Switzerland (2007-2012). We developed canton-specific interrupted time-series followed by random meta-analysis to evaluate the benefits of smoking bans on preterm (<37 gestational weeks) and early-term (37-38 gestational weeks) births. Heterogeneity across type of ban and contextual characteristics was explored through metaregression. A time-to-event approach was used for evaluating duration of pregnancy under the smoking bans and effects, taking into account individual maternal factors. We observed a decrease in the risk of preterm birth of 3.6% (95% CI, -9.3% to 2.5%), and early-term birth of 5.0% (95% CI -7.5% to -2.5%). Results showed a clear dose-response relationship. Greater risk reductions were obtained for preterm births in areas with more comprehensive bans (-6.8%; 95% CI -12.1% to 0.1%), and for pregnancies with the longest gestational time under smoking bans (HR, 0.991; 95% CI 0.984 to 0.997 per 10% increase in duration). Benefits were unequal across outcomes and characteristics of cantons and mothers. Smoking bans resulted in improved birth outcomes in Switzerland with cantons that adopted more comprehensive smoking bans achieving greater benefits. Early-term births constitute a previously ignored though important group. Published by the BMJ Publishing Group Limited.

UF insulation ban overturned by federal appeals court: but safety still in doubt

Betts, M.

1983-05-02

Unless the federal appeals court honors a US Consumer Product Safety Commission (CPSC) request to reconsider, the ban on sales of urea-formaldehyde (UF) foam for insulation will be lifted for want of evidence that it constitutes a health threat. The CPSC defends its analysis of flu-like symptoms and a form of cancer in laboratory animals which led to the ban on sales for school and home use, a ban which effectively eliminated all UF markets. Some buildings have replaced the foam with fiber and cellulose products at considerable expense. In overturning the ban, the court agreed with the UF foammore » industry challenge of CPSC evidence, but made no claim about UF safety. (DCK)« less

Multiple studies claim that public place smoking bans are associated with reductions in smoking-related hospitalization rates. No national study using complete hospitalization counts by area that accounts for contemporaneous controls including state cigarette taxes has been conducted. We examine the association between county-level smoking-related hospitalization rates and comprehensive smoking bans in 28 states from 2001 to 2008. Differences-in-differences analysis measures changes in hospitalization rates before versus after introducing bans in bars, restaurants, and workplaces, controlling for cigarette taxes, adjusting for local health and provider characteristics. Smoking bans were not associated with acute myocardial infarction or heart failure hospitalizations, but lowered pneumonia hospitalization rates for persons ages 60 to 74 years. Higher cigarette taxes were associated with lower heart failure hospitalizations for all ages and fewer pneumonia hospitalizations for adults aged 60 to 74. Previous studies may have overestimated the relation between smoking bans and hospitalizations and underestimated the effects of cigarette taxes. PMID:27624634

Is nonsmoking dangerous to the health of restaurants? The effect of California's indoor smoking ban on restaurant revenues.

Stolzenberg, Lisa; D'Alessio, Stewart J

2007-02-01

The state of California passed the Smoke-Free Workplace Act on January 1, 1995. This legislation effectively banned indoor smoking in all public and private workplaces including restaurants. Many restaurant owners, especially owners of restaurants that served alcohol, opposed the ban for fear that their businesses would be affected adversely because of the loss of patrons who smoked. Using an interrupted times-series autoregressive integrative moving average study design, the authors assess the effect of California's indoor smoking ban on revenue rates for all restaurants, for non-alcohol-serving restaurants, and for alcohol-serving restaurants. Results showed that revenues for alcohol-serving restaurants dropped by about 4% immediately following the establishment of the indoor smoking ban. However, this reduction was temporary because revenues for alcohol-serving restaurants quickly returned to normal levels. Findings also revealed that the indoor smoking ban had little observable impact on the revenue rate for restaurants overall and for non-alcohol-serving restaurants.

Smoking bans are a central component of comprehensive tobacco control programs, and an increasing number of states and localities have adopted them. Public support is critical as efforts continue to extend protection from secondhand smoke to all. We examine the relationship between state print news coverage of tobacco and public sentiment towards smoking bans. We utilize two data sources: the February 2002 Current Population Survey Tobacco Use Supplement, and articles from 2 months in a database comprised of content-analyzed newspaper articles on tobacco from all daily U.S. newspapers. We control for demographic and state-level tobacco covariates, and use logistic regression to identify associations between news coverage and attitudes towards policy initiatives by smoking status. We find no association between tone of news coverage and any outcome measure and little evidence of a relationship between the volume of overall tobacco news and attitudes towards smoking bans. Our data suggest that people exposed to more news on secondhand smoke issues are less likely to support restaurant smoking bans. Higher volume of secondhand smoke news is also predictive of lower support for bar bans among recent quitters. Support for hospital bans is, however, largely independent of news coverage. We suggest two alternate explanations for our findings. First, for certain people, greater news volume on secondhand smoke may lead to lower support for bans. Alternatively, secondhand smoke may be more newsworthy in states where bans are more controversial.

Smoking has become an important global problem that poses serious health hazards. Today even teenagers have got trapped by this addictive habit. To curb this menace, the Government of Tamilnadu has proposed a ban on smoking in public places by introducing the Bill "Tamilnadu Prohibition of Smoking and Spitting 2002". A study was conducted in the month of February, 2003 to find out the response to this proposed ban among health providers. One hundred and twenty-seven hospital employees were studied using a one page questionnaire. The prevalence of smoking was found to be 12.6% (95% CI 6.9 to 18.3). The response of the study group to the proposed ban was recorded by asking them about their awareness, acceptability and their personal opinion about the ban. It was found that 94% of the smokers and 83% of the non-smokers were aware of the proposed ban and 50% of the smokers and 69% of non-smokers wanted the ban to be implemented. It was also found that 43.8% of the smokers and 52.3% of the non-smokers were confident that the ban on smoking in public places will be effective. They were also of the opinion that awareness had to be increased and the penalties had to be implemented strictly. Further studies on other population groups may have to be taken upto know about the impact of this important Act after it comes into effect.

Background This is the first study to have examined the effect of smoking bans on hospitalizations in the Atlantic Canadian socio-economic, cultural and climatic context. On June 1, 2003 Prince Edward Island (PEI) enacted a province-wide smoking ban in public places and workplaces. Changes in hospital admission rates for cardiovascular (acute myocardial infarction, angina, and stroke) and respiratory (chronic obstructive pulmonary disease and asthma) conditions were examined before and after the smoking ban. Methods Crude annual and monthly admission rates for the above conditions were calculated from April 1, 1995 to December 31, 2008 in all PEI acute care hospitals. Autoregressive Integrated Moving Average time series models were used to test for changes in mean and trend of monthly admission rates for study conditions, control conditions and a control province after the comprehensive smoking ban. Age- and sex-based analyses were completed. Results The mean rate of acute myocardial infarctions was reduced by 5.92 cases per 100,000 person-months (P = 0.04) immediately after the smoking ban. The trend of monthly angina admissions in men was reduced by −0.44 cases per 100,000 person-months (P = 0.01) in the 67 months after the smoking ban. All other cardiovascular and respiratory admission changes were non-significant. Conclusions A comprehensive smoking ban in PEI reduced the overall mean number of acute myocardial infarction admissions and the trend of angina hospital admissions. PMID:23520450

The California antitobacco culture may have influenced home smoking bans in Mexico. Based on the Behavioral Ecological Model, exposure to socially reinforcing contingencies or criticism may explain adoption of home smoking bans in Tijuana, Mexico, approximating rates relative to San Diego, California, and higher than those in Guadalajara, Mexico. A representative cross-sectional population survey of Latinos (N = 1,901) was conducted in San Diego, Tijuana, and Guadalajara between June 2003 and September 2004. Cities were selected to represent high-, medium-, and low-level exposure to antitobacco social contingencies of reinforcement in a quasiexperimental analysis of possible cultural influences across borders. Complete home smoking ban prevalence was 91% in San Diego, 66% in Tijuana, and 38% in Guadalajara (p < .001). Sample cluster-adjusted logistic regression showed significantly lower odds of complete home smoking bans in Guadalajara (odds ratio [OR] = .048) and in Tijuana (OR = .138) compared to San Diego after control for demographics. Odds of complete home smoking bans in both Guadalajara and Tijuana in comparison with San Diego were weakened when mediators for bans were controlled in predictive models. Direction of association was consistent with theory. When theoretical mediators were explored as possible moderators, weak and nonsignificant associations were obtained for all interaction terms. Bootstrap analyses demonstrated that our multivariable logistic regression results were reliable. Results suggest that California antismoking social contingencies mediate complete home smoking bans in all 3 cities and may account for the greater effects in Tijuana contrasted with Guadalajara.

Formulado no final da década de 50, o modelo de percolação concentra-se em descrever o meio poroso, que será visto neste trabalho como uma rede de canais aleatórios, por onde escoa um fluido determinístico. Se o número de canais for suficientemente grande, então eles estarão ligados e o meio se tornará permeável à passagem do fluido. Neste caso, dizemos que houve a percolação do fluido. Reformulando o modelo acima, podemos escrever um código particularmente adaptado para simulações em Galáxias, onde iremos supor que os canais formam um reticulado, e que cada sítio da rede representa um poro que será interpretado como uma região ativa de formação estelar. Para cada elo teremos um pequeno canal ligando dois sítios vizinhos, que poderá, após um tempo "t", induzir ou não a formação de uma região ativa no poro vizinho. Para simular a passagem desta região ativa através dos poros, diremos que um elo está aberto com probabilidade p e fechado com probabilidade 1-p. Dessa forma, passamos a imaginar configurações de elos abertos e fechados, onde cada configuração ocorre com uma certa probabilidade, dada por p|A|(1-p)|F|, onde |A| é o número de elos abertos e |F| o número de elos fechados da configuração. A expressão anterior só tem importância física se |A| e |F| forem ambos finitos, pois, caso contrário, a probabilidade de ocorrência de uma dada configuração será sempre nula. Neste trabalho, foram considerados dados cinemáticos publicados na literatura bem como aqueles obtidos pelos autores a partir de observações fotométricas realizadas no Observatório de Las Campanãs, em 1994, para a Galáxia Anelada Peculiar HRG 03401. Mostraremos que para certos valores de p, situados entre 0,5 e 0,6, os clusters assim formados irão simular, de maneira coerente, o referido objeto.

Construção de um catálogo de aglomerados abertos para estudo da dinâmica da estrutura espiral da Galáxia

2003-08-01

Os aglomerados abertos são objetos de grande valor para o estudo da dinâmica da Galáxia devido esses objetos terem uma faixa de idade relativamente ampla. O trabalho visa estudar a dinâmica da estrutura espiral da Galáxia principalmente através do uso desses aglomerados, uma vez que o estudo da cinemática desses objetos é fundamental para esse objetivo. Nosso grupo trabalha no sentido de construir uma base de dados de aglomerados abertos contendo coordenadas, distância, idade, movimentos próprios e velocidades radiais e já disponibiliza uma nova versão do catálogo de aglomerados abertos o qual é uma compilação de edições anteriores, principalmente Lynga (1987), Mermilliod (1995) e ESO-B (Lauberts 1982). Nossa amostra possui cerca de 1630 aglomerados, mas nem todos os parâmetros acima citados foram determinados em sua totalidade. Para determinarmos esses parâmetros, derivamos as cores intrínsecas das estrelas membro de cada aglomerado a partir de seus tipos espectrais (busca feita no SIMBAD) obtendo assim o excesso de cor individual. A distribuição dos excessos de cor foi então utilizada para derivarmos o avermelhamento médio para cada aglomerado. De maneira similar, os tipos espectrais foram usados para estimar as magnitudes absolutas, e com as magnitudes absolutas e aparentes determinamos a respectiva distribuição do módulo de distância e finalmente a distância. Para determinar as idades foram confeccionados os diagramas cor-magnitude das estrelas de cada aglomerado onde foram superpostas a Seqüência Principal de Idade Zero (ZAMS). Superpomos a ZAMS de Schmidt-Kaler e isócronas de composição solar. Essas isócronas foram usadas para determinação das idades dos aglomerados. Uma vez que não temos ainda resultados finais, apresentamos então alguns diagramas cor-magnitude os quais foram usados para determinação, principalmente, da distância e idade dos aglomerados.

2014-08-01

Using a panel study design, we examined the effects of different types of texting bans on motor vehicular fatalities. We used the Fatality Analysis Reporting System and a difference-in-differences approach to examine the incidence of fatal crashes in 2000 through 2010 in 48 US states with and without texting bans. Age cohorts were constructed to examine the impact of these bans on age-specific traffic fatalities. Primarily enforced laws banning all drivers from texting were significantly associated with a 3% reduction in traffic fatalities in all age groups, and those banning only young drivers from texting had the greatest impact on reducing deaths among those aged 15 to 21 years. Secondarily enforced restrictions were not associated with traffic fatality reductions in any of our analyses.

To examine whether the nationwide smoking ban, imposed in 2007, had an impact on the profitability of Belgian restaurants. Objective financial reporting data on 1613 restaurants were analysed with return on assets as the outcome measure. The data were collected from the Belfirst database and cover the period 2004-2009. To assess the impact of the smoking ban, a differences-in-differences estimation method was used, with bars serving as the control group. The regression model was estimated, while controlling for firm-specific characteristics and unobserved firm-level heterogeneity. The variable of interest is the interaction between the smoking ban dummy and the dummy for the treatment group. The coefficient of this variable is insignificant. The adoption of the nationwide smoking ban did not affect the profitability of Belgian restaurants.

Breaking Habits: The Effect of the French Vending Machine Ban on School Snacking and Sugar Intakes.

PubMed

Capacci, Sara; Mazzocchi, Mario; Shankar, Bhavani

This paper estimates the effect of the 2005 vending machine ban in French secondary schools on nutrient intakes and on the frequency of morning snacking at school. Using data before and after the ban, and exploiting the discontinuity associated with the age-dependent exposure to the ban, we specify a difference-in-differences regression discontinuity design. Since the relationship between age-at-interview and school level is not precise, we introduce fuzziness in the model. We find that the ban has generated a 10-gram reduction in sugar intakes from morning snacks at school, and a significant reduction in the frequency of these morning snacks. However, we find no evidence that the intervention affects total daily intakes, and our results are suggestive of compensation effects.

Low-power secure body area network for vital sensors toward IEEE802.15.6.

Kuroda, Masahiro; Qiu, Shuye; Tochikubo, Osamu

2009-01-01

Many healthcare/medical services have started using personal area networks, such as Bluetooth and ZigBee; these networks consist of various types of vital sensors. These works focus on generalized functions for sensor networks that expect enough battery capacity and low-power CPU/RF (Radio Frequency) modules, but less attention to easy-to-use privacy protection. In this paper, we propose a commercially-deployable secure body area network (S-BAN) with reduced computational burden on a real sensor that has limited RAM/ROM sizes and CPU/RF power consumption under a light-weight battery. Our proposed S-BAN provides vital data ordering among sensors that are involved in an S-BAN and also provides low-power networking with zero-administration security by automatic private key generation. We design and implement the power-efficient media access control (MAC) with resource-constraint security in sensors. Then, we evaluate the power efficiency of the S-BAN consisting of small sensors, such as an accessory type ECG and ring-type SpO2. The evaluation of power efficiency of the S-BAN using real sensors convinces us in deploying S-BAN and will also help us in providing feedbacks to the IEEE802.15.6 MAC, which will be the standard for BANs.

To assess whether smoking ban policies are associated with smoking reduction and quit attempts among California smokers. Data were examined for 1718 current smokers from follow-up telephone interviews conducted in 2011 of persons previously identified as smokers in a representative sample of the adult population of California. Population weighted logistic regressions controlling for demographic and other variables were used to evaluate the association between smoking ban policies (home, work, and town) and changes in tobacco use (past year quit attempt or reduction in smoking rate). Living in a home with a total ban was significantly associated with smoking reduction (adjusted odds ratio, AOR: 2.4, 95% CI: 1.4-4.2) and making a quit attempt (AOR: 2.3, 95% CI: 1.3-3.9) compared to living in a home with no home ban. Self-reported perception of an outdoor ban in one's city/town was associated with smoking reduction (AOR: 1.7, 95% CI: 1.02-2.7) and making a quit attempt (AOR: 1.8, 95% CI: 1.05-2.9). These results indicate that smoking bans not only protect nonsmokers from the harms of secondhand smoke, but are also associated with smoking reduction and cessation. Copyright © 2013 Elsevier Inc.

2010-11-01

We examined the rate of acute myocardial infarction (AMI) deaths in Massachusetts before and after the implementation of a comprehensive smoke-free workplace law in July 2004. We used Poisson regression models to examine the impact of the state law in cities and towns with and without previous local smoking bans and the effect of the local laws for the period of 1999 through 2006. The AMI mortality rate decreased by 7.4% (95% confidence interval [CI] = 3.3%, 11.4%) after implementation of the state law. The state ban had an impact in cities and towns with no prior local smoking ban (9.2% decrease; P < .001) but not cities and towns with a prior local smoking ban. However, there was a nonsignificant 4.9% (95% CI = -5.0%, 13.9%) decrease associated with the local smoking ban that preceded the effect of the state ban. The effect of the state ban was modest (-1.6%) in the first 12 months after implementation but much larger after the first 12 months (-18.6%; P < .001). Comprehensive statewide smoke-free workplace laws in Massachusetts were associated with an estimated 270 fewer AMI deaths per year. These results add to the evidence suggesting that smoke-free air laws are associated with lower rates of AMI.

Correlates of household smoking bans in low-income families of children with and without asthma.

Exposure to secondhand smoke (SHS) harms all children's health, especially children with asthma. Yet, children with asthma are as likely to live with smokers as healthy children. Household smoking bans are being advocated to reduce children's harm from SHS. To measure the effect of household smoking bans on child SHS exposure and to examine correlates of strict smoking bans in a low-income, diverse sample, 91 children with asthma were matched to 91 healthy children. All had at least one smoker living in their homes. Nicotine dosimeters, child cotinine assays, and maternal reports quantified child SHS exposures. Maternal reports of household smoking rules, behaviors, and beliefs, and other family characteristics were also gathered. The presence of a strict household smoking ban vastly reduced children's SHS exposures and was associated with fewer cigarettes smoked by the mother and by other family members, the belief that SHS was a personal health risk, having children with asthma, and living in a single-family home. Many children are exposed to high levels of SHS at home. Strict household smoking bans greatly decrease, but do not eliminate children's SHS exposure. Even in disadvantaged families, mutable factors were associated with strict smoking bans. Increased dissemination and use of established public health strategies are needed to reduce children's SHS exposures.

Objectives. We assessed current home smoking behaviors and secondhand smoke (SHS) levels among parents of children in low-income, racial/ethnic minority communities in Massachusetts. Methods. We used a cross-sectional design to assess home smoking rules, smoking status, cigarettes smoked in the home, and barriers and benefits to attaining a smoke-free home among 138 caregivers (mean age = 30.0 years; 92% women) of children aged 0 to 6 years, between April 2010 and September 2012. Indoor SHS was assessed using a nicotine dosimeter. Results. Households with no ban reported a higher weekly mean number of cigarettes smoked in the home (114 cigarettes/week) than homes with partial (71 cigarettes/week) or complete (30 cigarettes/week) bans (P < .01). Smoking occurred outside more than inside homes with partial or complete bans. Air nicotine levels were positively associated with no household smoking ban, current smoking by the caregiver, and smoking indoors. Conclusions. Strategies to reduce home SHS should focus on a “complete” home smoking ban and smoking cessation. SHS mitigation strategies such as smoking outside were associated with lower SHS among participants unable to maintain a complete ban, and might enhance the likelihood of longer term success while immediately reducing home SHS.

We estimated the short-run economic impacts of the Scottish smoking ban on public houses. Previous findings on the effect of smoking bans on the hospitality sector have mainly focused on the United States. These studies have mostly found no negative economic effects of such legislation on the hospitality sector in the long run. However, differences in the social use of public houses in Great Britain in comparison with the United States may lead to different findings. We used a quasi-experimental research design that compared the sales and number of customers in public houses located in Scotland before and after the Scottish smoking ban was introduced, relative to a control group of establishments across the English border where no ban was imposed. To perform this analysis, we collected data on 2724 pubs, 1590 in Scotland and 1134 in Northern England by phone interviews using quota sampling. We found that the Scottish ban led to a 10% decrease in sales [P = 0.02, 95% confidence interval (CI) -19% to -2%] and a 14% decrease in customers (P = 0.02, 95% CI -26% to -2%). Our study suggests that the Scottish smoking ban had a negative economic impact on public houses, at least in the short run, due in part to a drop in the number of customers.

The influence of tobacco marketing on adolescent smoking intentions via normative beliefs.

Brown, Abraham; Moodie, Crawford

2009-08-01

Using cross-sectional data from three waves of the Youth Tobacco Policy Study, which examines the impact of the UK's Tobacco Advertising and Promotion Act (TAPA) on adolescent smoking behaviour, we examined normative pathways between tobacco marketing awareness and smoking intentions. The sample comprised 1121 adolescents in Wave 2 (pre-ban), 1123 in Wave 3 (mid-ban) and 1159 in Wave 4 (post-ban). Structural equation modelling was used to assess the direct effect of tobacco advertising and promotion on intentions at each wave, and also the indirect effect, mediated through normative influences. Pre-ban, higher levels of awareness of advertising and promotion were independently associated with higher levels of perceived sibling approval which, in turn, was positively related to intentions. Independent paths from perceived prevalence and benefits fully mediated the effects of advertising and promotion awareness on intentions mid- and post-ban. Advertising awareness indirectly affected intentions via the interaction between perceived prevalence and benefits pre-ban, whereas the indirect effect on intentions of advertising and promotion awareness was mediated by the interaction of perceived prevalence and benefits mid-ban. Our findings indicate that policy measures such as the TAPA can significantly reduce adolescents' smoking intentions by signifying smoking to be less normative and socially unacceptable.

To assess changes in hospitality workers' expectations and attitudes towards the Spanish smoking law before and 2 years after the smoking ban. We performed a longitudinal study of a cohort (n=431) of hospitality workers in five regions in Spain before the law came into effect and 24 months later. Expectations and attitudes towards the ban and knowledge about the effect of second-hand smoke on health were compared before and after the ban. We recruited 431 hospitality workers in the baseline survey and 219 were followed-up 24 months later (overall follow-up rate of 50.8%). The percentage of hospitality workers who knew the law was 79.0% before it was passed and was 94.1% 24 months later (p<0.05). We observed an increase in support to the smoke-free ban in all public places, including bars and restaurants (54.1% to 65.8%; p<0.05). The percentages of support for the current ban, perception of compliance with the ban by employees and customers, and knowledge of the effect of second-hand smoke on health also increased. Knowledge and support to the Spanish smoking law among hospitality workers increased 2 years after the implementation of the ban. Copyright 2009 SESPAS. Published by Elsevier Espana.

Chinese herbal medicine (CHM) has been commonly used in treating liver diseases in Asian countries. To conduct a large-scale pharmacoepidemiological study and evaluate the frequency and pattern of CHM prescriptions in treating chronic hepatitis. We obtained the database of traditional Chinese medicine outpatient claims from the national health insurance in Taiwan for the whole 2002. Patients with chronic hepatitis were identified by the corresponding diagnosis of International Classification of Disease among claimed visiting files. Corresponding prescription files were analyzed, and association rule were applied to evaluate the co-prescription of CHM in treating chronic hepatitis. Among the 91,080 subjects treated by CHM for chronic hepatitis, the peak age was in the 40 s, followed by 30 s and 50 s. Male/female ratio was 2.07:1. Long-dan-xie-gan-tang and Saliva miltiorrhiza (Dan-shen) were the most commonly prescribed Chinese herbal formula and single herbal drug, respectively. The most common two-drug prescription was Jia-wei-xia-yao-san plus Saliva miltiorrhiza, and the most common three-drug prescription was Jia-wei-xia-yao-san plus Saliva miltiorrhiza and Artemisia capillaries (Yin-chen-hao). This study showed the utilization pattern of Chinese herbal drugs or formulae in treating chronic hepatitis. Further researches and clinical trials are needed to evaluate the efficacy of these Chinese herbs or its ingredients in treating chronic hepatitis.

Water organic pollution and eutrophication influence soil microbial processes, increasing soil respiration of estuarine wetlands: site study in jiuduansha wetland.

Undisturbed natural wetlands are important carbon sinks due to their low soil respiration. When compared with inland alpine wetlands, estuarine wetlands in densely populated areas are subjected to great pressure associated with environmental pollution. However, the effects of water pollution and eutrophication on soil respiration of estuarine and their mechanism have still not been thoroughly investigated. In this study, two representative zones of a tidal wetland located in the upstream and downstream were investigated to determine the effects of water organic pollution and eutrophication on soil respiration of estuarine wetlands and its mechanism. The results showed that eutrophication, which is a result of there being an excess of nutrients including nitrogen and phosphorus, and organic pollutants in the water near Shang shoal located upstream were higher than in downstream Xia shoal. Due to the absorption and interception function of shoals, there to be more nitrogen, phosphorus and organic matter in Shang shoal soil than in Xia shoal. Abundant nitrogen, phosphorus and organic carbon input to soil of Shang shoal promoted reproduction and growth of some highly heterotrophic metabolic microorganisms such as β-Proteobacteria, γ-Proteobacteria and Acidobacteria which is not conducive to carbon sequestration. These results imply that the performance of pollutant interception and purification function of estuarine wetlands may weaken their carbon sequestration function to some extent.

In this study, two representative zones of a tidal wetland located in the upstream and downstream were investigated to determine the effects of water organic pollution and eutrophication on soil respiration of estuarine wetlands and its mechanism. The results showed that eutrophication, which is a result of there being an excess of nutrients including nitrogen and phosphorus, and organic pollutants in the water near Shang shoal located upstream were higher than in downstream Xia shoal. Due to the absorption and interception function of shoals, there to be more nitrogen, phosphorus and organic matter in Shang shoal soil than in Xia shoal. Abundant nitrogen, phosphorus and organic carbon input to soil of Shang shoal promoted reproduction and growth of some highly heterotrophic metabolic microorganisms such as β-Proteobacteria, γ-Proteobacteria and Acidobacteria which is not conducive to carbon sequestration. These results imply that the performance of pollutant interception and purification function of estuarine wetlands may weaken their carbon sequestration function to some extent. PMID:25993326

Treatment planning is a central part of radiation therapy, including delineation in tumor volumes and critical organs, setting treatment goals of prescription doses to the tumor targets and tolerance doses to the critical organs, and finally generation of treatment plans to meet the treatment goals. National groups like RTOG have led the effort to standardize treatment goals of the prescription doses to the tumor targets and tolerance doses to the critical organs based on accumulated knowledge from decades of abundant clinical trial experience. The challenge for each clinical department is how to achieve or surpass these set goals within themore » time constraints of clinical practice. Using fifteen testing cases from different treatment sites such as head and neck, prostate with and without pelvic lymph nodes, SBRT spine, we will present clinically utility of advanced planning tools, including knowledge based, automatic based, and multiple criteria based tools that are clinically implemented. The objectives of this session are: Understand differences among these three advanced planning tools Provide clinical assessments on the utility of the advanced planning tools Discuss clinical challenges of treatment planning with large variations in tumor volumes and their relationships with adjacent critical organs.

Air pollution in Boston bars before and after a smoking ban.

PubMed

Repace, James L; Hyde, James N; Brugge, Doug

2006-10-27

We quantified the air quality benefits of a smoke-free workplace law in Boston Massachusetts, U.S.A., by measuring air pollution from secondhand smoke (SHS) in 7 pubs before and after the law, comparing actual ventilation practices to engineering society (ASHRAE) recommendations, and assessing SHS levels using health and comfort indices. We performed real-time measurements of respirable particle (RSP) air pollution and particulate polycyclic aromatic hydrocarbons (PPAH), in 7 pubs and outdoors in a model-based design yielding air exchange rates for RSP removal. We also assessed ventilation rates from carbon dioxide concentrations. We compared RSP air pollution to the federal Air Quality Index (AQI) and the National Ambient Air Quality Standard (NAAQS) to assess health risks, and assessed odor and irritation levels using published SHS-RSP thresholds. Pre-smoking-ban RSP levels in 6 pubs (one pub with a non-SHS air quality problem was excluded) averaged 179 microg/m3, 23 times higher than post-ban levels, which averaged 7.7 microg/m3, exceeding the NAAQS for fine particle pollution (PM2.5) by nearly 4-fold. Pre-smoking ban levels of fine particle air pollution in all 7 of the pubs were in the Unhealthy to Hazardous range of the AQI. In the same 6 pubs, pre-ban indoor carcinogenic PPAH averaged 61.7 ng/m3, nearly 10 times higher than post-ban levels of 6.32 ng/m3. Post-ban particulate air pollution levels were in the Good AQI range, except for 1 venue with a defective gas-fired deep-fat fryer, while post-ban carcinogen levels in all 7 pubs were lower than outdoors. During smoking, although pub ventilation rates per occupant were within ASHRAE design parameters for the control of carbon dioxide levels for the number of occupants present, they failed to control SHS carcinogens or RSP. Nonsmokers' SHS odor and irritation sensory thresholds were massively exceeded. Post-ban air pollution measurements showed 90% to 95% reductions in PPAH and RSP respectively, differing little from outdoor concentrations. Ventilation failed to control SHS, leading to increased risk of the diseases of air pollution for nonsmoking workers and patrons. Boston's smoking ban eliminated this risk.

Environmental tobacco smoke (ETS) causes disease in nonsmokers. Workplace bans on smoking are interventions to reduce exposure to ETS to try to prevent harmful health effects. On March 29, 2004, the Irish government introduced the first national comprehensive legislation banning smoking in all workplaces, including bars and restaurants. This study examines the impact of this legislation on air quality in pubs and on respiratory health effects in bar workers in Dublin. Exposure study. Concentrations of particulate matter 2.5 microm or smaller (PM(2.5)) and particulate matter 10 microm or smaller (PM(10)) in 42 pubs were measured and compared before and after the ban. Benzene concentrations were also measured in 26 of the pubs. Health effects study. Eighty-one barmen volunteered to have full pulmonary function studies, exhaled breath carbon monoxide, and salivary cotinine levels performed before the ban and repeated 1 year after the ban. They also completed questionnaires on exposure to ETS and respiratory symptoms on both occasions. Exposure study. There was an 83% reduction in PM(2.5) and an 80.2% reduction in benzene concentration in the bars. Health effects study. There was a 79% reduction in exhaled breath carbon monoxide and an 81% reduction in salivary cotinine. There were statistically significant improvements in measured pulmonary function tests and significant reductions in self-reported symptoms and exposure levels in nonsmoking barmen volunteers after the ban. A total workplace smoking ban results in a significant reduction in air pollution in pubs and an improvement in respiratory health in barmen.

Objective Secondhand smoke exposure (SHSe) poses risks to hospitalized children upon discharge and no uniformly effective interventions have been identified. Understanding change-related processes and social-contextual factors related to motivation for implementing home and car smoking bans may inform interventions to reduce infant SHSe among mothers with a hospitalized infant. Methods In this cross-sectional, secondary analysis, mothers of neonatal ICU infants who reported smoking or living with a smoker (N=205) were assigned to stages of change (pre-contemplation, contemplation, preparation, or action) based on behaviors and intentions for establishing smoking bans in their homes and cars. Processes of change (POC) for SHSe reduction practices, self-efficacy, depressive symptoms, generalized anxiety, and social support for not smoking in the home were examined across all four stages. Results The majority of mothers were in the action stage for having a home smoking ban in place (55%); only 35% of participants were in action for a car smoking ban. POC use differed across the stages of change for having a home ban (p=0.004) and car ban (p=0.02), with earlier stages using fewer overall and relatively fewer cognitive/affective processes. Earlier stage women also reported lower self-efficacy to change, less familial and partner support for in-home smoking bans, and more depressive symptoms. Conclusions Novel intervention targets were identified, including cognitive/affective change processes, mental health, and familial/social contingencies for implementing SHSe protective practices. Creative ways in which to affect change at the individual and household level are needed in order to fully address the complexity of child SHSe. PMID:26914262

Sustainability of outdoor school ground smoking bans at secondary schools: a mixed-method study

Abstract Background Although increasing numbers of countries are implementing outdoor school ground smoking bans at secondary schools, less attention is paid to the post-implementation period even though sustainability of a policy is essential for long-term effectiveness. Therefore, this study assesses the level of sustainability and examines perceived barriers/facilitators related to the sustainability of an outdoor school ground smoking ban at secondary schools. Methods A mixed-method design was used with a sequential explanatory approach. In phase I, 438 online surveys were conducted and in phase II, 15 semi-structured interviews were obtained from directors of relevant schools. ANOVA (phase I) and a thematic approach (phase II) were used to analyze data. Results Level of sustainability of an outdoor school ground smoking ban was high at the 48% Dutch schools with an outdoor smoking ban. Furthermore, school size was significantly associated with sustainability. The perceived barriers/facilitators fell into three categories: (i) smoking ban implementation factors (side-effects, enforcement, communication, guidelines and collaboration), (ii) school factors (physical environment, school culture, education type and school policy) and (iii) community environment factors (legislation and social environment). Conclusions Internationally, the spread of outdoor school ground smoking bans could be further promoted. Once implemented, the ban has become ‘normal’ practice and investments tend to endure. Moreover, involvement of all staff is important for sustainability as they function as role models, have an interrelationship with students, and share responsibility for enforcement. These findings are promising for the sustainability of future tobacco control initiatives to further protect against the morbidity/mortality associated with smoking. PMID:29016786

Are Statewide Restaurant and Bar Smoking Bans Associated With Reduced Cigarette Smoking Among Those With Mental Illness?

PubMed Central

2014-01-01

Background: Smoke-free air laws have effectively reduced cigarette consumption at the population level; however, the influence of these policies on smoking among those with mental illness is unclear. We examined whether associations between statewide restaurant/bar smoking bans and cigarette smoking varied by psychiatric diagnoses and gender. Methods: We analyzed data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC, Wave 1: 2001–2002; Wave 2: 2004–2005; n = 7,317 smokers). All analyses were stratified by gender. We examined whether tobacco cessation was associated with the interaction between ban implementation and Wave 1 psychiatric diagnoses (alcohol use disorder [AUD], anxiety disorder [AD], or mood disorder), adjusting for relevant covariates. Among those who continued to use tobacco at Wave 2, we examined associations between Wave 2 cigarettes per day (CPD) and the diagnoses × ban interactions, controlling for Wave 1 CPD and other relevant covariates. Results: Among men with an AUD and women with an AD, ban implementation was associated with 6% and 10% greater probability of tobacco cessation at Wave 2, respectively. Among men in the overall sample, ban implementation was associated with smoking 0.8 fewer CPD at Wave 2. Associations with CPD were nonsignificant among women. Interactions between ban implementation and psychiatric diagnoses were also nonsignificant when examining CPD, suggesting consistent reductions in CPD among men but not among women. Conclusions: This study provided the first evidence that statewide restaurant/bar smoking bans may be associated with reduced smoking among those with select psychiatric conditions. PMID:24566280

[Recent developments on the European ban on animal experiments for cosmetics].

PubMed

Ruhdel, I W

2001-01-01

For the second time the European Commission has postponed the sales ban on cosmetics products that have been developed and tested in animal experiments now until 2002. In the meantime the Commission wants to adopt the Seventh Amendment of the EU Cosmetics Directive. In its draft the Commission proposes to scrap the sales ban and replace it with an animal testing ban. This change would avoid possible conflicts with the WTO, however, from the animal welfare point of view would result in animal testing moving into third countries instead of avoiding them. This is because cosmetics products tested on animals outside the EU could be sold in the EU without any restrictions. As a consequence this measure would take the pressure from authorities and industry to further develop and adopt alternative methods. Other proposed measures are not acceptable from the animal welfare point of view, e.g. because they contradict Directive 86/609 and would result in a delay of the application of validated alternative methods. The Deutscher Tierschutzbund therefore still demands an immediate and complete sales ban in connection with an animal testing ban within the EU.

The lectin from Musa paradisiaca binds with the capsid protein of tobacco mosaic virus and prevents viral infection.

It has been demonstrated that the lectin from Musa paradisiaca (BanLec-1) could inhibit the cellular entry of human immunodeficiency virus (HIV). In order to evaluate its effects on tobacco mosaic virus (TMV), the banlec-1 gene was cloned and transformed into Escherichia coli and tobacco, respectively. Recombinant BanLec-1 showed metal ions dependence, and higher thermal and pH stability. Overexpression of banlec-1 in tobacco resulted in decreased leaf size, and higher resistance to TMV infection, which includes reduced TMV cellular entry, more stable chlorophyll contents, and enhanced antioxidant enzymes. BanLec-1 was found to bind directly to the TMV capsid protein in vitro , and to inhibit TMV infection in a dose-dependent manner. In contrast to limited prevention in vivo , purified rBanLec-1 exhibited more significant effects on TMV infection in vitro . Taken together, our study indicated that BanLec-1 could prevent TMV infection in tobacco, probably through the interaction between BanLec-1 and TMV capsid protein.

ECG-cryptography and authentication in body area networks.

Zhang, Zhaoyang; Wang, Honggang; Vasilakos, Athanasios V; Fang, Hua

2012-11-01

Wireless body area networks (BANs) have drawn much attention from research community and industry in recent years. Multimedia healthcare services provided by BANs can be available to anyone, anywhere, and anytime seamlessly. A critical issue in BANs is how to preserve the integrity and privacy of a person's medical data over wireless environments in a resource efficient manner. This paper presents a novel key agreement scheme that allows neighboring nodes in BANs to share a common key generated by electrocardiogram (ECG) signals. The improved Jules Sudan (IJS) algorithm is proposed to set up the key agreement for the message authentication. The proposed ECG-IJS key agreement can secure data communications over BANs in a plug-n-play manner without any key distribution overheads. Both the simulation and experimental results are presented, which demonstrate that the proposed ECG-IJS scheme can achieve better security performance in terms of serval performance metrics such as false acceptance rate (FAR) and false rejection rate (FRR) than other existing approaches. In addition, the power consumption analysis also shows that the proposed ECG-IJS scheme can achieve energy efficiency for BANs.

The aim of this paper is to report compliance with the smoking ban and the spread of smoke-free homes after 3-8 years since the Italian smoking ban implementation, according to the ongoing Italian surveillance system for behavioural risk factors (PASSI). PASSI is based on representative annual samples of the Italian population aged 18-69 years. We considered questions on smoking habits, self-reported compliance with the ban, and on smoke-free homes of 176,236 interviews conducted in 2008-2012. Ninety percent of respondents in 2012 reported that the smoking ban was enforced in hospitality premises (HPs), with a significant 3% increase from 2008. Similarly, 91.3% in 2012 reported a high compliance in workplaces other than HPs, with a significant 5% increase. Perception of compliance did not change among smokers and non-smokers. Seventy-eight percent of respondents in 2012 reported smoke-free homes, with a significant increase from 2008 to 2012. The high compliance with the ban that is still increasing even after 8 years since its implementation may partially have caused the concurrent increase in smoke-free homes.

This study examined support for and reported compliance with smoke-free policy in air-conditioned restaurants and other similar places among adult smokers in Malaysia and Thailand. Baseline data (early 2005) from the International Tobacco Control Southeast Asia Survey (ITC-SEA), conducted face-to-face in Malaysia and Thailand (n = 4005), were used. Among those attending venues, reported total smoking bans in indoor air-conditioned places such as restaurants, coffee shops, and karaoke lounges were 40% and 57% in Malaysia and Thailand, respectively. Support for a total ban in air-conditioned venues was high and similar for both countries (82% Malaysian and 90% Thai smokers who believed there was a total ban), but self-reported compliance with bans in such venues was significantly higher in Thailand than in Malaysia (95% vs 51%, P < .001). As expected, reporting a ban in air-conditioned venues was associated with a greater support for a ban in such venues in both countries.

Butyltin compounds in liver of harbour porpoises (Phocoena phocoena) from the UK prior to and following the ban on the use of tributyltin in antifouling paints (1992-2005 & 2009).

Liver butyltin concentrations (monobutyl, dibutyl and tributyltin (TBT)) in harbour porpoises (n=410) have been determined during 1992-2005, and again in 2009 following a ban on the use of tributyltin-based antifouling paints on ships. The aim was to assess the effectiveness of the regulation, which was implemented during 2003-2008. Since the ban was put in place summed butyltin concentrations have declined. Also, the percentage of animals in which TBT was detected has fallen sharply, indicating the cessation of fresh inputs. In 1992, 1993 and 1995, TBT was detected in 100% of samples analysed. In 2003-2005, once the implementation of the ban had begun, this fell to 61-72%, and in 2009, following the completion of the ban, had reduced to 4.3% (i.e. in only 1 of 23 samples analysed). Thus we conclude that the ban has proved effective in reducing TBT inputs to the seas from vessels. Crown Copyright © 2012. Published by Elsevier Ltd. All rights reserved.

The Body Area Network (BAN) concept enables wireless communication between several miniaturized, intelligent Body Sensor (or actor) Units (BSU) and a single Body Central Unit (BCU) worn at the human body. A separate wireless transmission link from the BCU to a network access point--using different technology--provides for online access to BAN data via usual network infrastructure. BAN is expected to become a basic infrastructure element for service-based electronic health assistance: By integrating patient-attached sensors and control of mobile dedicated actor units, the range of medical workflow can be extended by wireless patient monitoring and therapy support. Beyond clinical use, professional disease management environments, and private personal health assistance scenarios (without financial reimbursement by health agencies/insurance companies), BAN enables a wide range of health care applications and related services.

Smoking bans, cigarette prices and life satisfaction.

PubMed

Odermatt, Reto; Stutzer, Alois

2015-12-01

The consequences of tobacco control policies for individual welfare are difficult to assess, even more so when related consumption choices challenge people's willpower. We therefore evaluate the impact of smoking bans and cigarette prices on subjective well-being by analyzing data for 40 European countries and regions between 1990 and 2011. We exploit the staggered introduction of bans and apply an imputation strategy to study the effect of anti-smoking policies on people with different propensities to smoke. We find that higher cigarette prices reduce the life satisfaction of likely smokers. Overall, smoking bans are barely related to subjective well-being, but increase the life satisfaction of smokers who would like to quit smoking. The latter finding is consistent with cue-triggered models of addiction and the idea of bans as self-control devices. Copyright © 2015 Elsevier B.V. All rights reserved.

The federal state of Bavaria, Germany enforced a comprehensive smoking ban across all enclosed public areas in 2008 to protect non-smokers from second-hand smoke (SHS). Evidence against displacement of smoking to homes is abundant, however long-term assessments are few. We aim to report prevalence of children's SHS exposure before and after the ban, parental smoking behaviour and exposure risk factors. Cross-sectional data of children aged 5-6 years old in Bavaria (n = 22 944) were collected in 2004/5 and 2005/6 (S1 and S2) before the ban and after in 2008/9 and 2012/13 (S4 and S6). Parents reported their child's home SHS exposure, in enclosed public areas and private cars. Adjusted multivariable logistic regression assessed changes across time and predicted risk factors. Children's home SHS exposure before the ban was 14.3% (S1), 14.1% (S2) and 12.8% (S4) directly after the ban to 7.2% (S6) (P<0.0001). The proportion of homes where at least one parent smoked significantly reduced from 12.78% (S1) to 4.94% (S6) (P<0.0001) and homes with voluntary smoke-free rules increased. Exposure in cafes, restaurants and private cars also decreased. No significant changes in the proportion of parents that ceased smoking due to the ban were found. Among others, low parental education, crowding and unemployment were risk factors for higher SHS exposure. Since the smoking ban, no long-term displacement of SHS to homes was observed. Social smoking norms appear to have shifted in favour of the ban. Social inequalities still exist and should be addressed to further minimise SHS exposure. © The Author 2016.

To obtain detailed information on patterns of driver cell phone use, including how often drivers talk and text, the extent to which they use hands-free devices, and knowledge of and reaction to state cell phone laws. Telephone surveys were conducted with 1219 drivers in the 48 contiguous U.S. states and the District of Columbia, using random samples of landline and cell phone numbers. Forty percent of drivers reported talking on phones at least a few times per week. The percentages were highest for males (49%) and drivers ages 25-29 (66%). The percentage of drivers who reported never talking on phones was higher in states with all-driver bans on handheld phone use (44%) than in states without a ban applying to all drivers (30%). The percentage of drivers who talk on phones and always talk hands-free was higher in states with all-driver handheld phone bans (22%) than where such bans are not in effect (13%). Thirteen percent of drivers reported some texting while driving, and this percentage was highest among drivers ages 18-24 (43%). Twelve percent of drivers in states with all-driver texting bans reported texting while driving, compared with 14 percent in states with no texting ban. Among drivers ages 18-24, the percentages were 45 and 48 percent, respectively. Most drivers reported talking on phones while driving, even though earlier surveys have found that most people think this behavior should be banned. Fewer drivers overall reported texting, but the frequency of texting was higher among young drivers. Laws banning handheld phone use seem to discourage some drivers from talking on any type of phone and motivate some drivers to talk hands-free. Laws banning texting while driving have little effect on the reported frequency of texting while driving in any age group.

Recent advances in medical and electronic technologies have introduced the use of Body Area Networks as a part of e-health, for constant and accurate monitoring of patients and the transmission as well as processing of the data to develop a holistic Electronic Health Record. The rising global population, different BAN manufacturers and a variety of medical systems pose the issue of interoperability between BANs and systems as well as the proper way to propagate medical data in an organized and efficient manner. In this paper, we describe BANs and propose the use of certain web technologies to address this issue.

Evidence and arguments on tobacco retail displays: marketing an addictive drug to children?

To investigate arguments for and against a ban on tobacco displays in New Zealand shops. Analysis of evidence from international experience and research studies, for the arguments used to oppose and support display bans; and 27 qualitative interviews with New Zealand ex-smokers, smokers, and retailers. The main arguments used to oppose display bans identified were: (1) Fears of financial losses for retailers, particularly for small stores; (2) Claims that tobacco is a 'normal' product; (3) 'Lack of evidence' about effectiveness of display bans; and (4) Fears of increased theft and risks to staff. The counter-arguments include: (1) The lack of evidence of significant short term adverse economic effects on retailers (including small stores) where display bans have been implemented; (2) Tobacco is a highly abnormal and hazardous retail product; (3) Evidence that tobacco displays influence initiation of smoking among children, increase impulse purchases, and are crucial to tobacco companies' marketing strategies; (4) Lack of evidence that display bans increase thefts and risks to staff. The qualitative interviews supported the counter arguments. Smokers and ex-smokers interviewed indicated that tobacco displays tempt smokers trying to quit. There was widespread support for a display ban among interviewees (including some retailers) mainly because it might reduce smoking uptake among children. Arguments for tobacco displays are contradictory, flawed, and unsupported by local and international research evidence, and by the overseas experience of tobacco-free display policies.

Global Evidence on the Association between POS Advertising Bans and Youth Smoking Participation.

Point-of-sale (POS) tobacco advertising has been linked to youth smoking susceptibility and experimental smoking. However, there is limited evidence of the association between POS advertising bans and youth smoking participation. This study aims to examine how such bans are associated with current smoking, daily smoking, and regular smoking (≥ 1 cigarettes per day) participation among youth. one to two waves (primarily one wave) of the Global Youth Tobacco Survey were conducted in 130 countries between 2007 and 2011. These surveys were linked to the WHO "MPOWER" data using country and year identifiers to analyze the association between POS advertising bans (a dichotomous measure of the existence of such bans) and smoking participation in the past month. Weighted logistic regressions were employed to analyze this association while controlling for age, gender, parents' smoking status, 6 MPOWER policy scores, and GDP per capita. We find that in countries with POS advertising bans, current smoking (OR = 0.73, p ≤ 0.1), daily smoking (OR = 0.70, p ≤ 0.1), and regular smoking (OR = 0.75, p ≤ 0.05) participation in the past month is significantly lower, suggesting that POS promotion bans can potentially reduce youth smoking. This study provides evidence to support the implementation of POS promotion regulations by the US FDA and implementation of the WHO FCTC guidelines regarding restrictions on tobacco POS promotion.

On the 29th March 2004 the Irish government introduced a comprehensive workplace smoking ban to protect the health of workers. This study evaluates the impact the ban had on staffing levels, customer numbers and smoking rates in a sample of 38 public houses in Dublin. A total of 38 public houses were visited prior to the introduction of the ban, each visit lasted at least three hours, and the number of staff, customers and the number of people smoking was recorded each hour. Follow-up visits were conducted exactly one year later, on the same day of the week and at the same time of day, allowing controlling for seasonal and weekday effects. There was a decrease (8.82%) in average staff levels while customer numbers increased by 11% and there was a dramatic reduction in numbers smoking on a visit to a pub (77.8%). The hospitality industry predicted major job losses as a consequence of the introduction of the smoking ban; this work has shown that there was no significant decrease in the number of staff employed or in customer numbers. There was full compliance, with no customers smoking inside the public houses following the introduction of the ban. The ban has been good for the industry, staff, and customers.

This paper introduces the sensor-networked IoT model as a prototype to support the design of Body Area Network (BAN) applications for healthcare. Using the model, we analyze the synergistic effect of the functional requirements (data collection from the human body and transferring it to the top level) and non-functional requirements (trade-offs between energy-security-environmental factors, treated as Quality-of-Service (QoS)). We use feature models to represent the requirements at the earliest stage for the analysis and describe a model-driven methodology to design the possible BAN applications. Firstly, we specify the requirements as the problem domain (PD) variability model for the BAN applications. Next, we introduce the generative technology (meta-programming as the solution domain (SD)) and the mapping procedure to map the PD feature-based variability model onto the SD feature model. Finally, we create an executable meta-specification that represents the BAN functionality to describe the variability of the problem domain though transformations. The meta-specification (along with the meta-language processor) is a software generator for multiple BAN-oriented applications. We validate the methodology with experiments and a case study to generate a family of programs for the BAN sensor controllers. This enables to obtain the adequate measure of QoS efficiently through the interactive adjustment of the meta-parameter values and re-generation process for the concrete BAN application.

The aim of this paper was to compare nicotine concentration in 28 hospitality premises (HPs) in Florence and Belluno, Italy, where a smoking ban was introduced in 2005, and in 19 HPs in Vienna, Austria, where no anti-smoking law entered into force up to now. Airborne nicotine concentrations were measured in the same HPs in winter 2002 or 2004 (pre-ban measurements) and winter 2007 (post-ban measurements). In Florence and Belluno, medians decreased significantly (P < 0.001) from 8.86 [interquartile range (IQR): 2.41-45.07)] before the ban to 0.01 microg/m3 (IQR: 0.01-0.41) afterwards. In Austria (no smoking ban) the medians collected in winters 2004 and 2007 were, respectively, 11.00 (IQR: 2.53-30.38) and 15.76 microg/m3 (IQR: 2.22-31.93), with no significant differences. Measurements collected in winter 2007 in 28 HPs located in Naples, Turin, Milan (0.01 microg/m3; IQR: 0.01-0.16) confirmed post-ban results in Florence and Belluno. The medians of nicotine concentrations in Italy and Austria before the Italian ban translates, using the risk model of Repace and Lowery, into a lifetime excess lung cancer mortality risk for hospitality workers of 11.81 and 14.67 per 10,000, respectively. Lifetime excess lung cancer mortality risks for bar and disco-pub workers were 10-20 times higher than that calculated for restaurant workers, both in Italy and Austria. In winter 2007, it dropped to 0.01 per 10,000 in Italy, whereas in Austria it remained at the same levels. The drop of second-hand smoke exposure indicates a substantial improvement in air quality in Italian HPs even after 2 years from the ban. The nation-wide smoking ban introduced in Italy on January 10, 2005, resulted in a drop in second-hand smoke exposure in hospitality premises, whereas in Austria, where there is no similar nation-wide smoking ban, the exposure to second-hand smoke in hospitality premises remains high. Given that second-hand smoke is considered a group 1 carcinogen according to the International Agency for Research on Cancer classification, the World Health Organization Framework Convention on Tobacco Control strongly recommends the implementation of nation-wide smoke-free policies in order to improve the indoor air quality of hospitality premises and workplaces. Results from our study strongly supports this recommendation.

Pesticide self-poisoning causes one third of global suicides. Sri Lanka halved its suicide rate by banning WHO Class I organophosphorus (OP) insecticides and then endosulfan. However, poisoning with Class II toxicity OPs, particularly dimethoate and fenthion, remains a problem. We aimed to determine the effect and feasibility of a ban of the two insecticides in one Sri Lankan district. Sale was banned in June 2003 in most of Polonnaruwa District, but not Anuradhapura District. Admissions with pesticide poisoning to the district general hospitals was prospectively recorded from 2002. Hospital admissions for dimethoate and fenthion poisoning fell by 43% after the ban in Polonnaruwa, while increasing by 23% in Anuradhapura. The pesticide case fatality fell from 14.4% to 9.0% in Polonnaruwa (odds ratio [OR] 0.59, 95% confidence interval [CI] 0.41-0.84) and 11.3% to 10.6% in Anuradhapura (OR 0.93, 95%CI 0.70-1.25; p = 0.051). This reduction was not sustained, with case fatality in Polonnaruwa rising to 12.1% in 2006-2007. Further data analysis indicated that the fall in case fatality had actually been due to a coincidental reduction in case fatality for pesticide poisoning overall, in particular for paraquat poisoning. We found that the insecticides could be effectively banned from agricultural practice, as shown by the fall in hospital admissions, with few negative consequences. However, the ban had only a minor effect on pesticide poisoning deaths because it was too narrow. A study assessing the agricultural and health effects of a more comprehensive ban of highly toxic pesticides is necessary to determine the balance between increased costs of agriculture and reduced health care costs and fewer deaths.

Lectins as carbohydrate-binding proteins have been employed in various biological assays for the detection and characterization of glycan structures on glycoproteins, including clinical biomarkers in disease states. A mannose-specific banana lectin (BanLec) is unique in its specificity for internal alpha1,3 linkages as well as beta1,3 linkages at the reducing termini. The immunomodulatory potential of natural BanLec was recognized by a strong immunoglobulin G4 antibody response and T cell mitogen activity in humans. To explore its applicability in glycoproteomics and its modulatory potential, the gene of banana lectin was cloned, sequenced and a recombinant protein was produced in Escherichia coli. The obtained cDNA revealed a novel banana lectin isoform, with an open reading frame of 426 nucleotides, encoding a cytoplasmatic protein of 141 amino acids. The molecular mass of rBanLec determined by ESI FT-MS and N-terminal sequencing confirmed the cDNA at the protein level. The specificity of rBanLec for detection glycan structures was the same as for natural BanLec as examined with five protein extracts rich in glycoprotein content, as well as with horseradish peroxidase glycoprotein. Besides, the immunomodulatory potential of rBanLec and nBanLec were comparable as assessed by an inhibition assay and a human T cell proliferation assay where they induced a strong proliferation response in CD3+, CD4+, and CD8+ populations of human PBMCs. This recombinant BanLec is a useful reagent for glycoproteomics and lectin microarrays, with a potential for modulation of the immune response.

Clove cigar sales following the US flavoured cigarette ban.

Following the passage of the Family Smoking Prevention and Tobacco Control Act in 2009, flavoured cigarettes, including clove cigarettes, were banned based on the rationale that such cigarettes appealed to youth. However, the ban on characterising flavours was not extended to cigars. This study reviewed industry documents from Kretek International, the parent company behind Djarum clove cigars, to document the changes in their marketing and production strategies following the flavour ban on cigarettes. To assess sales trends following the ban, data for clove cigar sales in the USA from 2009 to 2012 were analysed using Nielsen's Convenience Track retail scanner database. Additionally, data on tobacco imports to the USA from Indonesia were obtained from the USDA Foreign Agricultural Service's Global Agricultural Trade System for the years 2008-2012. In anticipation of Food and Drug Administration's (FDA) flavour ban on cigarettes and recognising the regulatory advantages of cigars, Kretek International began developing Djarum clove cigars in 2007. Immediately following the flavour ban, sales of this product increased by more than 1400% between 2009 and 2012. During this same period, tobacco imports to the USA from Indonesia, a leader in clove tobacco production, shifted from cigarettes to almost exclusively cigars. Kretek International, like other tobacco manufacturers, manipulated its products following the Family Smoking Prevention and Tobacco Control Act as a way to capitalise on regulatory loopholes and replace its now banned clove cigarettes. As a result, consumption of the company's Djarum clove cigars increased exponentially in recent years. Published by the BMJ Publishing Group Limited.

Legislation to ban smoking in public places is currently a major area of interest across Canada. The main objectives of the study were to 1) determine the effect of the smoking ban on incidence of acute myocardial infarction, 2) determine if the new legislation altered population-based smoking prevalence, and 3) measure public support for the public smoking ban. The city of Saskatoon initiated a public smoking ban on July 1, 2004. We retrospectively reviewed all hospital discharges for acute MI from July 2000 to June 2005. We reviewed CCHS survey information on smoking prevalence for Saskatoon, Saskatchewan and Canada from 2003 to 2005. We prospectively contacted 1,255 Saskatoon residents by telephone to determine support for the public smoking ban. The age-standardized incidence rate of acute MI fell from 176.1 (95% CI 165.3-186.8) cases per 100,000 population (July 1, 2000 to June 30, 2004) to 152.4 (95% CI 135.3-169.3) cases per 100,000 population (July 1, 2004 to June 30, 2005). Smoking prevalence in Saskatoon fell from 24.1% in 2003 (95% CI 20.4-27.7) to 18.2% in 2005 (95% CI 15.7-20.9) while smoking prevalence in Saskatchewan remained unchanged at 23.8% (95% CI 22.6-25.3) and Canada reduced from 22.9% (95% CI 22.5-23.3) to 21.3% (95% CI 20.8-21.8). Seventy-nine percent of Saskatoon residents believed the smoking ban was a good idea. The public smoking ban in Saskatoon, Canada, is associated with reduced incidence rates of acute MI, lower smoking prevalence and high levels of public support.

The current study examined home and full (i.e., home plus car) smoking ban adoption as secondary outcomes to a randomized controlled trial targeting reduced secondhand smoke exposure (SHSe) for children under treatment for cancer. Families with at least 1 adult smoker who reported SHSe for their children (n = 119) were randomized to control or intervention conditions and followed for 1 year with 5 assessments. Both groups were advised of the negative health outcomes associated with SHSe; the intervention group provided more in-depth counseling from baseline to 3 months. Parents reported on household and car smoking behavior, demographic, psychosocial, and medical/treatment-related information. Regardless of group assignment, there was an increase in home (odds ration [OR] = 1.16, p = .074) and full (OR = 1.37, p = .001) smoking ban adoption across time. Families in the intervention group were more likely to adopt a full ban by 3 months, but this difference was nonsignificant by 12 months. Married parents (OR = 2.33, p = .006) and those with higher self-efficacy for controlling children's SHSe (OR = 1.11, p = .023) were more likely to have a home smoking ban; parents who reported smoking fewer cigarettes were more likely to adopt a home (OR = 1.62, p < .0001) or full (OR = 7.32, p = .038) ban. Smoking bans are in-line with Healthy People 2020's tobacco objectives and may be more feasible for parents with medically compromised children for immediate SHSe reduction. Furthermore, interventions targeting full smoking bans may be a more effective for comprehensive elimination of SHSe.

2012-04-01

A ban on smoking in the workplace was introduced in Ireland on March 29, 2004. As exposure to secondhand smoke has been implicated in the development of coronary disease, this might impact the incidence of acute coronary syndromes (ACS). The smoking ban was associated with a decreased rate of hospital admissions for ACS. We analyzed data collected in a registry of all patients admitted to hospital with ACS in the southwest of Ireland, catchment population 620 525, from March 2003 until March 2007. In the year following implementation of the ban, there was a significant 12% reduction in ACS admissions (177.9 vs 205.9/100,000; 95% confidence interval [CI]: 164.0-185.1, P = 0.002). This reduction was due to fewer events occurring among men (281.5 vs 233.5, P = 0.0011) and current smokers (408 vs 302 admissions, P < 0.0001). There was no change in the rate of admissions for ACS in the following year (174.3/100,000; 95% CI: 164.0-185.1, P > 0.1). However, a further 13% reduction was observed between March 2006 and March 2007 (149.2; 95% CI: 139.7-159.2). Variation in admissions with time as a continuous variable also demonstrated a reduction on implementation of the smoking ban. A national ban on smoking in public places was associated with an early significant decrease in hospital admissions for ACS, suggesting a rapid effect of banning smoking in public places on ACS. A further reduction of similar magnitude 2 years after implementation of the ban is consistent with a longer-term effect that should be further examined in long-term studies. © 2012 Wiley Periodicals, Inc.

We report the evidence base that supported the decision to implement the first campus-wide hospital smoking ban in the Republic of Ireland with effect from 1 January 2009. Three separate data sources are utilized; surveillance data collected from patients and staff in 8 surveys between 1997 and 2006, a 1-week observational study to assess smoker behaviour in designated smoking shelters and an attitudinal interview with 28 smoker patients and 30 staff on the implications of the 2004 indoors workplace smoking ban, conducted in 2005. The main outcome measures were trends in prevalence of smoking over time according to age, sex and occupational groups and attitudes to the 2004 ban and a projected outright campus ban. Smoking rates among patients remained steady, 24.2% in 1997/98 and 22.7% in 2006. Staff smoking rates declined from 27.4% to 17.8%, with a strong occupational gradient. Observational evidence suggested a majority of those using smoking shelters in 2005 were women and health-care workers rather than patients. Attitudes of patients and staff were positive towards the 2004 ban, but with some ambivalence on the effectiveness of current arrangements. Staff particularly were concerned with patient safety issues associated with smoking outdoors. The 2004 ban was supported by 87.6% of patients and 81.3% of staff in 2006 and a majority of 58.6% of patients and 52.4% of staff agreed with an outright campus ban being implemented. These findings were persuasive in instigating a process in 2007/08 to go totally smoke-free by 2009, the stages for which are discussed.

Tobacco smoke is known to affect plasma levels of some drugs, including the antipsychotic clozapine. The effects of suddenly stopping smoking on patients who take clozapine can be severe, as plasma concentrations are expected to rapidly rise, potentially leading to toxicity. A ban on smoking at South London and the Maudsley NHS Foundation Trust (SLaM) was implemented in 2014, and this was expected to affect the plasma concentrations of clozapine for inpatients at the time. This study aimed to determine whether plasma concentrations of clozapine were affected, and additionally, in line with observations from other authors, whether levels of reported violence would also be affected. The smoking habits of all patients at SLaM who smoked and were prescribed clozapine were recorded both before and after the ban. The Glasgow Antipsychotic Side Effect Scale for Clozapine (GASS-C) scale was used to evaluate side-effect burden. Clozapine doses and plasma concentrations were also collected. In total, 31 patients were included in this study. The mean clozapine dose before the ban was 502 mg/day, and this did not change significantly after the ban. Similarly, there were no significant changes in clozapine or norclozapine plasma concentrations, or in GASS-C scores. There was no change in the amount of tobacco patients reported smoking before or after the ban. A modest but statistically significant reduction in violent incidences was observed. Our data suggest that a ban on smoking for patients taking clozapine on open wards at inpatient hospital sites had little impact on clozapine plasma concentrations, because patients continued to smoke tobacco if allowed to leave. Smoking bans may result in a reduction in violent incidences.

Few reports exist on the association of a public smoking ban with fetal outcomes and maternal smoking in the United States. We sought to evaluate the effect of a citywide smoking ban in comparison to a like municipality with no such ban in Colorado on maternal smoking and subsequent fetal birth outcomes. A citywide smoking ban in Colorado provided a natural experiment. The experimental citywide smoking ban site was implemented in Pueblo, Colorado. A comparison community was chosen that had no smoking ban, El Paso County, with similar characteristics of population, size, and geography. The two sites served as their own controls, as each had a preban and postban retrospective observation period: preban was April 1, 2001, to July 1, 2003; postban was April 1, 2004, to July 1, 2006. Outcomes were maternal smoking (self-report), low birth weight (LBW) (defined as <2500 g or as <3000 g), and preterm births (<37 weeks gestation) in singleton births from mothers residing in these cities and reported to the State Department of Public Health. A difference-in-differences estimator was used to account for site and temporal trends in multivariate models. Compared to El Paso County preban, the odds of maternal smoking and preterm births were, respectively, 38% (p<0.05) and 23% (p<0.05) lower in Pueblo. The odds for LBW births decreased by 8% for <3000 g and increased by 8.4% for <2500 g; however, neither was significant. This is the first evidence in the United States that population-level intervention using a smoking ban improved maternal and fetal outcomes, measured as maternal smoking and preterm births.

Secondhand smoke exposure (SHSe) poses risks to hospitalized children upon discharge and no uniformly effective interventions have been identified. Understanding change-related processes and social-contextual factors related to motivation for implementing home and car smoking bans may inform interventions to reduce infant SHSe among mothers with a hospitalized infant. In this cross-sectional, secondary analysis, mothers of neonatal ICU infants who reported smoking or living with a smoker (N=205) were assigned to stages of change (pre-contemplation, contemplation, preparation, or action) based on behaviors and intentions for establishing smoking bans in their homes and cars. Processes of change (POC) for SHSe reduction practices, self-efficacy, depressive symptoms, generalized anxiety, and social support for not smoking in the home were examined across all four stages. The majority of mothers were in the action stage for having a home smoking ban in place (55%); only 35% of participants were in action for a car smoking ban. POC use differed across the stages of change for having a home ban (p=0.004) and car ban (p=0.02), with earlier stages using fewer overall and relatively fewer cognitive/affective processes. Earlier stage women also reported lower self-efficacy to change, less familial and partner support for in-home smoking bans, and more depressive symptoms. Novel intervention targets were identified, including cognitive/affective change processes, mental health, and familial/social contingencies for implementing SHSe protective practices. Creative ways in which to affect change at the individual and household level are needed in order to fully address the complexity of child SHSe. Copyright © 2016 Elsevier Ltd. All rights reserved.

Effects of a provincial ban of two toxic organophosphorus insecticides on pesticide poisoning hospital admissions

PubMed Central

2012-01-01

Background. Pesticide self-poisoning causes one third of global suicides. Sri Lanka halved its suicide rate by banning WHO Class I organophosphorus (OP) insecticides and then endosulfan. However, poisoning with Class II toxicity OPs, particularly dimethoate and fenthion, remains a problem. We aimed to determine the effect and feasibility of a ban of the two insecticides in one Sri Lankan district. Methods. Sale was banned in June 2003 in most of Polonnaruwa District, but not Anuradhapura District. Admissions with pesticide poisoning to the district general hospitals was prospectively recorded from 2002. Results. Hospital admissions for dimethoate and fenthion poisoning fell by 43% after the ban in Polonnaruwa, while increasing by 23% in Anuradhapura. The pesticide case fatality fell from 14.4% to 9.0% in Polonnaruwa (odds ratio [OR] 0.59, 95% confidence interval [CI] 0.41–0.84) and 11.3% to 10.6% in Anuradhapura (OR 0.93, 95%CI 0.70–1.25; p = 0.051). This reduction was not sustained, with case fatality in Polonnaruwa rising to 12.1% in 2006–2007. Further data analysis indicated that the fall in case fatality had actually been due to a coincidental reduction in case fatality for pesticide poisoning overall, in particular for paraquat poisoning. Conclusions. We found that the insecticides could be effectively banned from agricultural practice, as shown by the fall in hospital admissions, with few negative consequences. However, the ban had only a minor effect on pesticide poisoning deaths because it was too narrow. A study assessing the agricultural and health effects of a more comprehensive ban of highly toxic pesticides is necessary to determine the balance between increased costs of agriculture and reduced health care costs and fewer deaths.

Although increasing numbers of countries are implementing outdoor school ground smoking bans at secondary schools, less attention is paid to the post-implementation period even though sustainability of a policy is essential for long-term effectiveness. Therefore, this study assesses the level of sustainability and examines perceived barriers/facilitators related to the sustainability of an outdoor school ground smoking ban at secondary schools. A mixed-method design was used with a sequential explanatory approach. In phase I, 438 online surveys were conducted and in phase II, 15 semi-structured interviews were obtained from directors of relevant schools. ANOVA (phase I) and a thematic approach (phase II) were used to analyze data. Level of sustainability of an outdoor school ground smoking ban was high at the 48% Dutch schools with an outdoor smoking ban. Furthermore, school size was significantly associated with sustainability. The perceived barriers/facilitators fell into three categories: (i) smoking ban implementation factors (side-effects, enforcement, communication, guidelines and collaboration), (ii) school factors (physical environment, school culture, education type and school policy) and (iii) community environment factors (legislation and social environment). Internationally, the spread of outdoor school ground smoking bans could be further promoted. Once implemented, the ban has become 'normal' practice and investments tend to endure. Moreover, involvement of all staff is important for sustainability as they function as role models, have an interrelationship with students, and share responsibility for enforcement. These findings are promising for the sustainability of future tobacco control initiatives to further protect against the morbidity/mortality associated with smoking. © The Author 2017.

Liquorice is the root of Glycyrrhiza uralensis Fisch. or Glycyrrhiza glabra L., Leguminosae. Licorice is described as 'National Venerable Master' in Chinese medicine and plays paradoxical roles, i.e. detoxification/strengthen efficacy and inducing/enhancing toxicity. Therefore, licorice was called "Two-Face" herb in this paper. The aim of this study is to discuss the paradoxical roles and the perspective usage of this "Two-Face" herb using data mining and frequency analysis. More than 96,000 prescriptions from Chinese Formulae Database were selected. The frequency and the prescription patterns were analyzed using Microsoft SQL Server 2000. Data mining methods (frequent itemsets) were used to analyze the regular patterns and compatibility laws of the constituent herbs in the selected prescriptions. The result showed that licorice (Radix glycyrrhizae) was the most frequently used herb in Chinese Formulae Database, other frequently used herbs including Radix Angelicae Sinensis (Dang gui), Radix et rhizoma ginseng (Ren shen), etc. Toxic herbs such as Radix aconiti lateralis praeparata (Fu zi), Rhizoma pinelliae (Ban xia) and Cinnabaris (Zhu sha) are top 3 herbs that most frequently used in combination with licorice. Radix et rhizoma ginseng (Ren shen), Poria (Fu ling), Radix Angelicae Sinensis (Dang gui) are top 3 nontoxic herbs that most frequently used in combination with licorice. Moreover, Licorice was seldom used with sargassum (Hai Zao), Herba Cirsii Japonici (Da Ji), Euphorbia kansui (Gan Sui) and Flos genkwa (Yuan Hua), which proved the description of contradictory effect of Radix glycyrrhizae and these herbs as recorded in Chinese medicine theory. This study showed the principle pattern of Chinese herbal drugs used in combination with licorice or not. The principle patterns and special compatibility laws reported here could be useful and instructive for scientific usage of licorice in clinic application. Further pharmacological and chemical researches are needed to evaluate the efficacy and the combination pattern of these Chinese herbs. The mechanism of the combination pattern of these prescriptions should also be investigated whether additive, synergistic or antagonistic effect exist using in vitro or in vivo models.

Patients with vertigo are reported to exhibit a higher risk of subsequent stroke. However, it remains unclear if Traditional Chinese Medicine (TCM), the most common form of complementary and alternative medicine, can help lower the risk of stroke for these patients. So the aim of the study was to investigate the effects of TCM on stroke risk among patients with vertigo. This longitudinal cohort study used the Taiwanese National Health Insurance Research Database to identify 112,458 newly diagnosed vertigo patients aged ≥20 years who received treatment between 1998 and 2007. Among these patients, 53,203 (47.31%) received TCM after vertigo onset (TCM users), and the remaining 59,201 patients were designated as a control group (non-TCM users). All enrollees received follow-up until the end of 2012 to measure stroke incidence. Cox proportional hazards regression was used to compute the hazard ratio (HR) of stroke in recipients of TCM services. During 15-year follow-up, 5532 TCM users and 12,295 non-TCM users developed stroke, representing an incidence rate of 13.10% and 25.71% per 1000 person-years. TCM users had a significantly reduced risk of stroke compared to non-TCM users (adjusted HR=0.64; 95% confidence interval CI=0.59-0.74). The predominant effect was observed for those receiving TCM for more than 180 days (adjusted HR=0.52; 95% CI=0.49-0.56). Commonly used TCM formulae, including Ban-Xia-Bai-Zhu-Tian-Ma-Tang, Ling-Gui-Zhu-Gan-Tang, Bai Zhi (Angelica dahurica (Hoffm.) Benth. & Hook.f. ex Franch. & Sav., root), Ge Gen (Pueraria lobata (Willd.) Ohwi, root) and Hai Piao Xiao (Endoconcha Sepiae, Cuttlefish Bone) were significantly associated with lower risk of stroke. Results of this population-based study support the effects of TCM on reducing stroke risk, and may provide a reference for stroke prevention strategies. The study results may also help to integrate TCM into clinical intervention programs that provide a favorable prognosis for vertigo patients. Copyright © 2016 Elsevier Ireland Ltd.

Amphetamine use by truck drivers for occupational purposes is widely known. The production and consumption of amphetamines was banned by the Brazilian National Health Surveillance Agency (ANVISA) in October 2011. This study analyzes persistent amphetamine use by truck drivers since the ban was implemented. A convenience sample of 427 truck drivers was taken along highways in São Paulo State in 2012. Participants were asked to answer a structured questionnaire and provide a urine sample to screen for recent amphetamine consumption through toxicological analysis. Among the interviewed drivers, 7% had used some illicit drug recently and 2.7% had used amphetamines. Amphetamines are still consumed by truck drivers despite the risks and the recent ban. The authorities should thus monitor the possession and use of amphetamines by drivers in order to effectively enforce the ban.

Effects of a Driver Cellphone Ban on Overall, Handheld, and Hands-Free Cellphone Use While Driving: New Evidence from Canada.

2015-11-01

We provide new evidence on the effects of increasingly common driver cellphone bans on self-reported overall, handheld, and hands-free cellphone use while driving by studying Ontario, Canada, which instituted a 3-month education campaign in November 2009 followed by a binding driver cellphone ban in February 2010. Using residents of Alberta as a control group in a difference-in-differences framework, we find visual and regression-based evidence that Ontario's cellphone ban significantly reduced overall and handheld cellphone use. We also find that the policies significantly increased hands-free cellphone use. The reductions in overall and handheld use are driven exclusively by women, whereas the increases in hands-free use are much larger for men. Our results provide the first direct evidence that cellphone bans have the unintended effect of inducing substitution to hands-free devices. Copyright © 2014 John Wiley & Sons, Ltd.

[High time for a total ban on smoking in the hotel, restaurant and catering industry: the arguments are mounting].

PubMed

Hassink, R J; Franke, L J A

2007-02-24

Active and passive smoking are well-known causes of disease, including respiratory and cardiovascular disease and cancer. In 2004 the Dutch government introduced new legislation to regulate smoking in the workplace. However, smoking is still allowed in hotels, bars and restaurants, despite the fact that two-thirds of the Dutch population support a total ban on smoking in public places. Several other European countries and American states have banned smoking in public places. Studies performed in these regions show that the new smoking regulations have had no negative economic effects. Moreover, various studies have shown that smoking bans have a positive impact on public health, even in the short-term, including a significant decrease in respiratory and cardiovascular disease. There is therefore no reason to continue to exclude hotels, bars and restaurants from the smoking ban in all public places in The Netherlands.

Trends and the Economic Effect of Asbestos Bans and Decline in Asbestos Consumption and Production Worldwide

Although some countries have reduced asbestos consumption and instituted bans, other countries continue to produce and consume asbestos even as asbestos-related deaths mount and the associated societal costs are high. Asbestos production and consumption has declined globally; the number of bans has increased; and the speed at which countries have tapered off consumption has increased. Using country-level data, we study the economic impact of historical changes in the production and use of asbestos. We compare changes in gross domestic product (GDP) following the enactment of asbestos bans. We do not find any significant effect on GDP following an asbestos ban. In a regional case study, we compare changes in GDP and employment with changes in asbestos production. Regional-level data revealed a temporary employment decline at the local level that was then reversed. PMID:29547510

Wildlife trade is a major pathway for introduction of invasive species worldwide. However, how exactly wildlife trade influences invasion risk, beyond the transportation of individuals to novel areas, remains unknown. We analyze the global trade network of wild-caught birds from 1995 to 2011 as reported by CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora). We found that before the European Union ban on imports of wild-caught birds, declared in 2005, invasion risk was closely associated with numbers of imported birds, diversity of import sources, and degree of network centrality of importer countries. After the ban, fluxes of global bird trade declined sharply. However, new trade routes emerged, primarily toward the Nearctic, Afrotropical, and Indo-Malay regions. Although regional bans can curtail invasion risk globally, to be fully effective and prevent rerouting of trade flows, bans should be global. PMID:29181443

Temporal change in tributyltin (TBT) levels in Jinhae Bay, which has various TBT sources, was investigated in water, sediments, and oysters from 2003 to 2013 after its total ban in South Korea. The seawater TBT levels decreased over 500-fold from 1995/97 to 2008/09. The oyster TBT levels were about fourfold lower in 2012/13 than in 1995/97. However, the sediment TBT levels did not significantly change, even 10 years after the partial TBT ban on small ships and 7 years after the total TBT ban on all oceangoing vessels in Korea. The total ban of TBT use effectively reduced water and oyster TBT levels in Jinhae Bay, but TBT levels in water, oysters, and sediment remained above the global environmental quality standards established to protect marine organisms.

Asbestos poisons World Trade Organization atmosphere.

Kazan-Allen, L

2001-01-01

In September 2000, a World Trade Organization (WTO) panel published its findings in the dispute between Canada and the European Union/France over France's ban on the import and use of chrysotile (white asbestos). The panel upheld the French ban, established that the use of chrysotile is a health risk and the idea of "controlled use" a fallacy, and used (for the first time) an exception clause in the General Agreement on Tariffs and Trade that permits trade-restrictive measures to protect human life or health. At the same time, the panel concluded that the French ban violated international trade laws by treating chrysotile products less favorably than domestically produced alternatives. Some WTO watchers believe that with asbestos as the precedent for bans on toxic substances, the regulation of other, much less well-established, toxic exposures could prove much more difficult. Now the French ban has been upheld, chrysotile producers will increasingly target developing countries. Canada is appealing the WTO decision.

2015-01-01

CVS Health has taken a strategic marketing move by banning tobacco sales. They risk losing customers who buy medications and cigarettes at their drugstores. They estimate they will lose 2 billion dollars by banning cigarette sales. CVS Health believes they will benefit from being regarded as health care partner by insurers and banning cigarette sales is an important step in being recognized as such. The Affordable Care Act expanded access to pharmacy-based medical clinics, increased affordability of medications, and expanded the clinical role of pharmacists. CVS Health is positioning itself to take advantage of these changes.

Experimental economics' inconsistent ban on deception.

PubMed

Hersch, Gil

2015-08-01

According to what I call the 'argument from public bads', if a researcher deceived subjects in the past, there is a chance that subjects will discount the information that a subsequent researcher provides, thus compromising the validity of the subsequent researcher's experiment. While this argument is taken to justify an existing informal ban on explicit deception in experimental economics, it can also apply to implicit deception, yet implicit deception is not banned and is sometimes used in experimental economics. Thus, experimental economists are being inconsistent when they appeal to the argument from public bads to justify banning explicit deception but not implicit deception. Copyright © 2015 Elsevier Ltd.

2003-10-01

To examine community attitudes towards environmental tobacco smoke in licensed premises after the Sharp case decision. 723 randomly selected New South Wales residents aged 18 years and over completed a telephone survey in November 2001. The vast majority supported some form of smoking restriction in licensed clubs (92.1%) and hotels (90.0%). Compared with a 2000 survey, respondents in the 2001 survey were significantly more likely to support a total smoking ban in licensed clubs and hotels. When support was assessed using a ban-only question, 66.8% supported banning smoking in pubs/clubs. Approximately half reported being less likely to visit non-eating areas of licensed clubs (51.2%) and hotels (49.8%) if smoking were permitted and these proportions were significantly higher than in the 2000 survey. A majority (83.1%) thought bar workers' health should be a major consideration when deciding how to handle smoking in pubs/clubs. More than half (56.8%) believed pubs/clubs would experience significant financial problems if smoking bans were introduced. In New South Wales, majority support exists for banning smoking in pubs and clubs. Legislation banning smoking in all indoor drinking and gaming areas should be introduced immediately.

EU sales ban on new cosmetics tested on animals: impact on alternative methods, WTO implications and animal welfare aspects.

PubMed

Ruhdel, Irmela W

2004-06-01

In 1993, the European Union (EU) adopted Directive 93/35/EEC, calling for a sales ban on new cosmetic products containing ingredients tested on animals after 1 January, 1998, provided that alternative methods had been developed by then. In May 2000, for the second time, the European Commission postponed that ban. The Commission justified the repeated postponement of the sales ban by saying that no animal-free methods were available, although three in vitro methods were scientifically approved in 1997. With three years delay, these methods have been published and therefore "made available" in the EU. OECD acceptance is still awaited. Another reason for the postponement was the fear of possible World Trade Organisation (WTO) conflicts. However, according to WTO rules, the protection of public morality or animal health could justify a restriction of the free trade principle. From the animal welfare point of view, an unqualified EU sales ban, combined with an animal testing ban, would provide the incentive to further promote the development and acceptance of alternative methods and to prove that ethical standards are legitimate concerns under WTO rules.

Objectives. We studied the effect of home smoking bans on transitions in smoking behavior during emerging adulthood. Methods. We used latent transition analysis to examine movement between stages of smoking from late adolescence (ages 16–18 years) to young adulthood (ages 18–20 years) and the effect of a home smoking ban on these transitions. We used data from the Minnesota Adolescent Community Cohort study collected in 2004 to 2006. Results. Overall, we identified 4 stages of smoking: (1) never smokers, (2) experimental smokers, (3) light smokers, and (4) daily smokers. Transition probabilities varied by stage. Young adults with a home ban during late adolescence were less likely to be smokers and less likely to progress to higher use later. Furthermore, the protective effect of a home smoking ban on the prevalence of smoking behavior was evident even in the presence of parental smoking. However, this effect was less clear on transitions over time. Conclusions. In addition to protecting family members from exposure to secondhand smoke, home smoking bans appear to have the additional benefit of reducing initiation and escalation of smoking behavior among young adults.

Smoking outside: the effect of the Irish workplace smoking ban on smoking prevalence among the employed.

Savage, Michael

2014-10-01

In March 2004, Ireland became the first country to introduce a nationwide workplace smoking ban. The primary aim of the ban was to reduce people's exposure to second-hand smoke. A 95% compliance rate among employers suggests this aim was achieved. By prohibiting smoking in the majority of indoor working places, an effect of the ban was to increase the non-monetary cost of smoking. The aim of this paper is to examine whether the extra non-monetary cost of smoking was concentrated on the employed. A difference-in-differences approach is used to measure changes in smoking behaviour among the employed relative to the non-working population following the introduction of the workplace smoking ban. The research finds that the workplace smoking ban did not induce a greater reduction in smoking prevalence among the employed population compared with the non-working population. In fact, the evidence suggests a significantly larger decrease in smoking prevalence among the non-workers relative to the employed. Changes in the real price of cigarettes and changes in attitudes to risk are discussed as possible causes for the pattern observed.

There are two models for the origins and timing of the Bronze Age in Southeast Asia. The first centres on the sites of Ban Chiang and Non Nok Tha in Northeast Thailand. It places the first evidence for bronze technology in about 2000 B.C., and identifies the origin by means of direct contact with specialists of the Seima Turbino metallurgical tradition of Central Eurasia. The second is based on the site of Ban Non Wat, 280 km southwest of Ban Chiang, where extensive radiocarbon dating places the transition into the Bronze Age in the 11th century B.C. with likely origins in a southward expansion of technological expertise rooted in the early states of the Yellow and Yangtze valleys, China. We have redated Ban Chiang and Non Nok Tha, as well as the sites of Ban Na Di and Ban Lum Khao, and here present 105 radiocarbon determinations that strongly support the latter model. The statistical analysis of the results using a Bayesian approach allows us to examine the data at a regional level, elucidate the timing of arrival of copper base technology in Southeast Asia and consider its social impact.

Should flavours be banned in cigarettes and e-cigarettes? Evidence on adult smokers and recent quitters from a discrete choice experiment.

2018-05-28

To provide the policy-relevant estimates of impacts of alternative flavour bans on preferences and demand for cigarettes and e-cigarettes in adult smokers and recent quitters. A best-best discrete choice experiment (DCE) is used to elicit smokers' and recent quitters' preferences for flavours, price, health impact and nicotine level in cigarettes and e-cigarettes. Choice of tobacco products and an opt-out option were examined. An efficient design yielded 36 choice sets. Exploded logit choice models were estimated. Flavour bans are modelled by restricting flavour coefficients in the estimated model. A sample of 2031 adult smokers and recent quitters was recruited to complete an online survey and DCE. Current smokers and recent quitters, on average, prefer cigarettes and menthol cigarettes over flavoured e-cigarettes. However, there is substantial preference heterogeneity by younger adults (ages 18-25), race/ethnicity and respondents with higher education. Our predictions suggest that a ban on menthol cigarettes would produce the greatest reduction in the choice of cigarettes (-5.2%), but with an accompanying increase in e-cigarettes use (3.8%). In contrast, banning flavours in e-cigarettes, while allowing menthol in cigarettes would result in the greatest increase in the selection of cigarettes (8.3%), and a decline in the use of e-cigarettes (-11.1%). A ban on all flavours, but tobacco in both products would increase 'opting-out' the most (5.2%) but would also increase choice of cigarettes (2.7%) and decrease choice of e-cigarettes (-7.9%). A ban on flavoured e-cigarettes alone would likely increase the choice of cigarettes in smokers, arguably the more harmful way of obtaining nicotine, whereas a ban on menthol cigarettes alone would likely be more effective in reducing the choice of cigarettes. A ban on all flavours in both products would likely reduce the smoking/vaping rates, but the use of cigarettes would be higher than in the status quo. Policy-makers should use these results to guide the choice of flavour bans in light of their stance on the potential health impacts both products. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

2013-09-01

The aim of the study is to describe attitudes which underlie Pole's declarations of support for a smoking ban in public places. The qualitative study using semi-structured individual in-depth interviews was conducted. The 30 IDI-s (in depth interviews) being a part of a larger research project entitled 'Lay meanings of health and life orientation of Polish society versus prevention and health promotion attitudes' were realized between 2007-2009. People belonging to all key socio-demographic categories identified by variables such as sex, age, education, and place of domicile were interviewed. The resulting material was subjected to content analysis. In the study the structural concept of 'attitude' was adopted. In order to identify the attitudes towards smoking bans in public places statements related to all three components of attitudes were analysed, but the typology of attitudes was constructed mainly on the basis of the emotional-evaluative component. The study identified as many as four attitudes behind the declared support for a smoking ban in public places. Those attitudes were labelled 'supportive', 'accepting', 'conditionally accepting', and 'ambivalent'. They differ as regards degree of acceptance for the ban, conviction about harmfulness of passive smoking, setting great store by other regulators of smoking like cultural norms or healthy consciousness, and propensity to observe and execute the smoking ban. The 'supportive' attitude can be characterized not only by total support for the smoking ban in public places but also by insistence on the need for its extension. The 'accepting' attitude means approval for the smoking ban, and the 'conditionally accepting' attitude is distinguished from the others by the stress put on the right of smokers to have an access to places where smoking is permitted. The 'ambivalent' attitude can be typified by underlining other than legal ways of influencing smoking in public places. The study suggests that the attitudes underlying the Pole's declarations of support for a smoking ban in public places can be differentiated. However, because of the low number of participants in the study the results should be verified thus the further research is needed. Therefore, there is a need not only to study people's declaration of support or objection for the smoking ban in public places but also to examine their attitudes including cognitive and behavioural components using both qualitative and quantitative methods of social research.

Objective To study possible cross shift effects of environmental tobacco smoke (ETS) on pulmonary function among bar and restaurant employees before and after the implementation of a smoking ban in Norway. Methods The study included 93 subjects employed in 13 different establishments in Oslo. They were examined at the beginning and end of a workshift both while ETS exposure was present and when smoking was banned. The mean exposure level of nicotine and total dust before the ban was 28 μg/m3 (range 3–65) and 275 μg/m3 (range 81–506), respectively. Following the smoking ban, the mean level of nicotine and total dust was 0.6 μg/m3 and 77 μg/m3, respectively. Assessment of lung function included dynamic lung volumes and flows. Results The cross shift reduction in forced vital capacity (FVC) among 69 subjects participating in both examinations changed from 81 ml (SD 136) during exposure to ETS to 52 ml (SD 156) (p = 0.24) following the smoking ban. The reduction in forced expired volume in one second (FEV1) during a workshift, was borderline significantly reduced when comparing the situation before and after the intervention, by 89 ml (SD = 132) compared to 46 ml (SD = 152) (p = 0.09), respectively. The reduction in forced mid‐expiratory flow rate (FEF25–75%) changed significantly from 199 ml/s (SD = 372) to 64 ml/s (SD = 307) (p = 0.01). Among 26 non‐smokers and 11 asthmatics, the reduction in FEV1 and FEF25–75% was significantly larger during ETS exposure compared to after the smoking ban. There was an association between the dust concentration and decrease in FEF25–75% before the ban among non‐smokers (p = 0.048). Conclusions This first study of cross shift changes before and after the implementation of a smoking ban in restaurants and bars shows a larger cross shift decrease in lung function before compared with after the implementation of the ban.

Ban-Lan-Gen is the common name for the dried roots of indigo plants, including Polygonum tinctorium, Isatis indigotica, Isatis tinctoria, and Strobilanthes cusia. Ban-Lan-Gen is frequently used as an anti-inflammatory and an anti-viral for the treatment of hepatitis, influenza, and various types of inflammation. One of the cytochrome P450 (CYP) enzymes, CYP3A4, is responsible for the metabolism of a wide variety of xenobiotics, including an estimated 60% of all clinically used drugs. In this study, we investigated the effect of Ban-Lan-Gen on the transcriptional activation of the CYP3A4 gene. Ban-Lan-Gen extract increased CYP3A4 gene reporter activity in a dose-dependent manner. Indirubin, one of the biologically active ingredients in the Ban-Lan-Gen, also dose-dependently increased CYP3A4 gene reporter activity. Expression of short hairpin RNA for the human pregnane X receptor (hPXR-shRNA) inhibited CYP3A4 gene reporter activity, and overexpression of human PXR increased indirubin- and rifampicin-induced CYP3A4 gene reporter activity. Furthermore, indirubin induced CYP3A4 mRNA expression in HepG2 cells. Taken together, these results indicate that indirubin, a component of Ban-Lan-Gen, activated CYP3A4 gene transcription through the activation of the human PXR. Copyright © 2016.

Smoking bans in public places have been shown to have an impact on smoking habits, however the potential influence of a university smoking ban on faculty and staff smoking habits remains elusive. This cross sectional study was implemented in Nayoro City, Japan in 2011, among the faculty and students of the Nayoro City University. Five years after the declaration of a total ban on smoking on a university campus, the smoking characteristics of all students, teachers and office workers, and the policy's impact on smokers were investigated. The survey was conducted through an anonymous, self-administered, multiple-choice questionnaire. Information was gathered on the characteristics and smoking characteristics of respondents, and the smokers attitudes toward smoking. The recovery rate was 62.1%. Among respondents, smoking prevalence was 17.9% in teachers and office workers, and 4.0% in students. Among all smokers, 46.4% did not abstain from smoking while at the university and they indicated their smoking areas were "on the streets next to the campus": 16 and "outdoors on campus": 3, respectively. As for smokers, 29.6% of them reduced the number of cigarettes smoked per day as a result of the smoking ban. None of the ex-smokers replied that their principal motivation for quitting smoking was the smoking ban. The ban on smoking served a motivator for smokers to reduce in smoking, but not serve as an effective motivator to quit smoking.

We examined prescribing patterns for nicotine replacement therapies (NRTs) in a large psychiatric hospital, before and after the implementation of a smoking ban. We extracted 5 years of NRT utilization data from hospital pharmacy records. The ban went into effect on January 1, 2007. Data reflect NRT prescriptions from 2 years before and 3 years after the ban, and N = 30,908 total inpatient hospital admissions. The monthly rate of total NRT prescriptions increased after the ban from M = 254.25 (SD = 126.60) doses per month to M = 4,467.52 (SD = 1,785.87) doses per month (>1,700% increase, p < .0001). After the smoking ban, clinicians prescribed higher doses of transdermal (but not oral) NRT (Tukey, p < .0001). Comparisons of NRT prescribing across hospital units tentatively suggested that patients being treated on the substance use disorders unit were prescribed more doses of NRT, as well as higher doses of NRT compared with patients on other units. Analysis of trends over time showed no apparent downward trend for NRT usage during the 3 years following the smoking ban, suggesting that clinicians continued to treat nicotine dependence after smoking was restricted. Clinicians are more likely to identify and treat symptoms of nicotine withdrawal when smoking is restricted. Hospitals should consider monitoring prescriptions for NRT as part of their ongoing quality assurance practices so that patients receive aggressive treatment of nicotine withdrawal symptoms--an essential component of high-quality patient care.

Does a ban on informal health providers save lives? Evidence from Malawi

PubMed Central

Godlonton, Susan; Okeke, Edward N.

2015-01-01

Informal health providers ranging from drug vendors to traditional healers account for a large fraction of health care provision in developing countries. They are, however, largely unlicensed and unregulated leading to concern that they provide ineffective and, in some cases, even harmful care. A new and controversial policy tool that has been proposed to alter household health seeking behavior is an outright ban on these informal providers. The theoretical effects of such a ban are ambiguous. In this paper, we study the effect of a ban on informal (traditional) birth attendants imposed by the Malawi government in 2007. To measure the effect of the ban, we use a difference-in-difference strategy exploiting variation across time and space in the intensity of exposure to the ban. Our most conservative estimates suggest that the ban decreased use of traditional attendants by about 15 percentage points. Approximately three quarters of this decline can be attributed to an increase in use of the formal sector and the remainder is accounted for by an increase in relative/friend-attended births. Despite the rather large shift from the informal to the formal sector, we do not find any evidence of a statistically significant reduction in newborn mortality on average. The results are robust to a triple difference specification using young children as a control group. We examine several explanations for this result and find evidence consistent with quality of formal care acting as a constraint on improvements in newborn health. PMID:26681821

Aims To evaluate the impact of the 2011 Scottish ban on multi-buy promotions of alcohol in retail stores. Design and setting Difference-in-differences analysis was used to estimate the impact of the ban on the volume of alcohol purchased by Scottish households, compared with those in England and Wales, between January 2010 and June 2012. Participants A total of 22 356 households in Scotland, England and Wales. Measurements Records of alcohol purchasing from each of four categories (beer and cider, wine, spirits and flavoured alcoholic beverages), as well as total volume of pure alcohol purchased. Findings Controlling for general time trends and household heterogeneity, there was no significant effect of the multi-buy ban in Scotland on volume of alcohol purchased either for the whole population or for individual socio-economic groups. There was also no significant effect on those who were large pre-ban purchasers of alcohol. Most multi-buys were for beer and cider or for wine. The frequency of shopping trips involving beer and cider purchases increased by 9.2% following the ban (P < 0.01), while the number of products purchased on each trip decreased by 8.1% (P < 0.01). For wine, however, these effects were not significant. Conclusions Banning multi-buy promotions for alcohol in Scotland did not reduce alcohol purchasing in the short term. Wider regulation of price promotion and price may be needed to achieve this. PMID:24251415

Global Evidence on the Association between POS Advertising Bans and Youth Smoking Participation

2016-01-01

Background: Point-of-sale (POS) tobacco advertising has been linked to youth smoking susceptibility and experimental smoking. However, there is limited evidence of the association between POS advertising bans and youth smoking participation. This study aims to examine how such bans are associated with current smoking, daily smoking, and regular smoking (≥1 cigarettes per day) participation among youth. Methods: one to two waves (primarily one wave) of the Global Youth Tobacco Survey were conducted in 130 countries between 2007 and 2011. These surveys were linked to the WHO “MPOWER” data using country and year identifiers to analyze the association between POS advertising bans (a dichotomous measure of the existence of such bans) and smoking participation in the past month. Weighted logistic regressions were employed to analyze this association while controlling for age, gender, parents’ smoking status, 6 MPOWER policy scores, and GDP per capita. Results and Conclusions: We find that in countries with POS advertising bans, current smoking (OR = 0.73, p ≤ 0.1), daily smoking (OR = 0.70, p ≤ 0.1), and regular smoking (OR = 0.75, p ≤ 0.05) participation in the past month is significantly lower, suggesting that POS promotion bans can potentially reduce youth smoking. This study provides evidence to support the implementation of POS promotion regulations by the US FDA and implementation of the WHO FCTC guidelines regarding restrictions on tobacco POS promotion.

How do government regulations influence the ability to practice Chinese herbal medicine in western countries.

The regulation policies of substances used in Chinese Herbal Medicine (CHM), have a direct influence on the ability of health providers to practice in the clinic. We set out to assess the truth behind the assumption that practice of CHM in the west is constrained by the regulations imposed by authorities in western countries. For the first part of our study we surveyed and compiled lists of banned and restricted Chinese Materia Medica (CMM) from six countries: USA, UK, Germany, Israel, Canada and Australia. Afterwards, we estimated the relevant importance of the 300 CMM most-commonly-prescribed to the practice of CHM according to prescriptions from 2,000,000 randomly selected patients, from the Taiwanese National Health Insurance Research Database (NHIRD). We then compared both lists and determined the clinical importance of the banned and restricted CMM. Except for regulations from Canada, most of the information of banned CMM proved to be difficult to organize. The USA was found to have the least amount of banned herbs, with 9 substances. Canada had the highest amount, with 98. In Germany, Australia, the UK, and Israel 10, 29, 36, 68 banned CMM were found, respectively. Apart from aristolochic acid containing substances, ma huang (, Ephedra sinica) was the only CMM banned in all countries. Most of the banned CMM were not found to be among the most-commonly-prescribed according to the NHIRD. Authorities should make this information more accessible. No clear relation exists between CHM regulations and any 'Western' common denominator, and the amount of banned CMM varied greatly among the surveyed countries. However, even among countries with a larger amount of banned CMM, the majority of these were in the bottom two-thirds in respect to the frequency of their use. Thus, regulations in some western countries surely influence the practice of CHM, however, the variability of CMM have been influenced by regulations only to a limited extent.

2015-03-01

To assess the impact of the Western Australian tobacco point-of-sale display ban on spontaneous purchase behaviours. Daily adult smokers (n=402) observed purchasing cigarettes were recruited via exit interviews either 2 months before or after the implementation of the display ban. Smokers were asked if they had intended to purchase cigarettes before entering the store to assess spontaneous purchase behaviours. Whether smokers had noticed the displays before their purchase and the extent to which this influenced their purchase decision was also assessed via non-prompting questions. When compared with before the ban, fewer smokers after the ban noticed the displays (27.1% vs 1.1%, p<0.001), fewer reported making spontaneous purchases (28.2% vs 19.8%, p<0.05) and fewer claimed the displays influenced their purchase decisions (free recall 5.0% vs 1.1%, p<0.05; cued recall 22.1% vs 3.8%, p<0.001). Before the ban, spontaneous purchasers were more likely than planned purchasers to suggest the displays influenced their purchase decisions (free recall 9.7% vs 3.2%, p<0.05; cued recall 40.0% vs 17.9%, p<0.01). After the ban, spontaneous purchasers nominating the influence of displays fell substantially (free recall 9.7% vs 5.6%, p=NS; cued recall 40.0% vs 11.1%, p<0.01) as it did for planned purchasers (free recall 3.2% vs 0.0%, p<0.05; cued recall 17.9% vs 2.1%, p<0.01). We observed a 30% reduction in smokers making spontaneous tobacco purchases after implementation of the Western Australian tobacco display ban and between a fivefold and sixfold reduction in the proportion suggesting displays influenced their decision to purchase cigarettes. These data are consistent with previous research suggesting tobacco displays encourage spontaneous purchases and their removal corresponds to reductions in the same.

The Thai Health Promotion Foundation supported the Improvement of Quality of Life of Informal Workers project in Ban Luang District, Amphur Photaram, Ratchaburi Province. There were many informal workers in Ban Luang District. Sweet-crispy fish producers in Ban Luang were the largest group among the sweet-crispy fish producers in Thailand. This project was aimed at improving living and working conditions of informal workers, with a focus on the sweet-crispy fish group. Good practices of improved living and working conditions were used to help informal workers build safe, healthy and productive work environments. These informal workers often worked in substandard conditions and were exposed to various hazards in the working area. These hazards included risk of exposure to hot work environment, ergonomics-related injuries, chemical hazards, electrical hazards etc. Ergonomics problems were commonly in the sweet-crispy fish group. Unnatural postures such as prolonged sitting were performed dominantly. One hundred and fifty informal workers participated in this project. Occupational health volunteers were selected to encourage occupational health and safety in four groups of informal workers in 2009. The occupational health volunteers trained in 2008 were farmers, beauty salon workers and doll makers. The occupational health and safety knowledge is extended to a new informal worker group: sweet-crispy fish producer, in 2009. The occupational health and safety training for sweet-crispy fish group is conducted by occupational health volunteers. The occupational health volunteers increased their skills and knowledge assist in to make safe home and safe community through participatory oriented training. The improvement of living and working condition is conducted by using a modified WISH, Work Improvement for Safe Home, checklist. The plans of improvement were recorded. The informal workers showed improvement mostly on material handling and storage. The safe uses and safe storage of chemicals were introduced among farmers. The awareness of healthcare using personal protective equipments is increased in all groups especially in farmers. Safe home by local occupational health volunteer is proposed to be one effective measure for improvement of quality of life.

Coagulation factors (II, VII, IX, X, and particularly XIa) remaining in high concentrations in intravenous immunoglobulin (IVIG) preparations can form thrombi, causing thromboembolic events, and in serious cases, result in death. Therefore, manufacturers of biological products must investigate the ability of their production processes to remove procoagulant activities. Previously, we were able to remove coagulation factors II, VII, IX, and X from our IVIG preparation through ethanol precipitation, but factor XIa, which plays an important role in thrombosis, remained in the intermediate products. Here, we used a chromatographic process using a new resin that binds with high capacity to IgG and removes procoagulant activities. The procoagulant activities were reduced to low levels as determined by the thrombin generation assay: <1.56 mIU/mL, chromogenic FXIa assay: <0.16 mIU/mL, non-activated partial thromboplastin time (NaPTT): >250 s, FXI/FXIa ELISA: <0.31 ng/mL. Even after spiking with FXIa at a concentration 32.5 times higher than the concentration in normal specimens, the procoagulant activities were below the detection limit (<0.31 ng/mL). These results demonstrate the ability of our manufacturing process to remove procoagulant activities to below the detection limit (except by NaPTT), suggesting a reduced risk of thromboembolic events that maybe potentially caused by our IVIG preparation.

The objective of this study was to investigate the attitudes of restaurant managers, employees and customers towards a total smoking ban policy in restaurants. A restaurant based survey in an urban area of Kunming City, China, was carried out from May to August 2009. One hundred managers, 1,055 employees and 5,213 customers aged 15 years or above were interviewed using a structured questionnaire. The percentage of respondents supporting a total smoking ban in restaurants was 17% among managers, 13.4% among employees, and 16.6% among customers. Multilevel analysis confirmed respondents who did not smoke, who were educated, and who worked or dined at a restaurant with fewer than 200 seats were more likely to support a total smoking ban. A total smoking ban in restaurants is unlikely to be supported by people involved in the restaurant business in the study area. This coincides with poor awareness of the harms of smoking.

Striving for quality use of medicines: how effective is Australia's ban on direct-to-consumer prescription medicine advertising?

PubMed

Brown, Sonja

2009-02-01

The potential for both positive and negative effects arising from direct-to-consumer advertising of prescription medicines challenges health policymakers to develop regulatory schemes which selectively capture the positive aspects of the practice. Australia has dealt with this quandary by banning the practice, while New Zealand and the United States permit it. However, in recent times pharmaceutical companies have been increasingly successful in introducing promotional materials into the Australian market. This article demonstrates that the Australian ban is consistent with striving for the major policy goal of quality use of medicines, thus providing the basis for arguing that solutions to strengthen the ban against the identified threats ought to be implemented. Quality use of medicines can be most effectively achieved via the combined effect of the strengthened ban and the mimicking of the limited positive aspects of direct-to-consumer advertising by government provision of non-promotional information to consumers.

Getting the story straight. The press and "partial-birth abortion".

PubMed

Farmer, A

2000-06-01

This paper discusses the controversy of the banning of ¿partial-birth abortion¿ in the state of Nebraska. This controversy arises as a result of how several major news sources described the Nebraska statute--that is, as a pre-viability abortion ban, and not a ban on late-term abortion procedures. This issue did not only occur in Nebraska, but also in Michigan when abortion opponents simultaneously initiated a publicity scheme to mislead the public into believing the ban was about ¿gruesome¿ late-term procedures. The deceptive term ¿partial-birth abortion¿, also seemed to suggest abortions performed on viable fetuses and the language describing the ban was confusing and slippery. In response to this controversy, Janet Benshoof, the president of the Center for Reproductive Law and Policy (CRLP) immediately made a statement to counteract the allegation imposed by abortion opponents. Also, CRLP Communications Deputy Director Margie Kelly spends a considerable amount of time informing the press of the extreme measures of the laws.

A novel strategy which combines iteratively cubic spline fitting baseline correction method with discriminant partial least squares qualitative analysis is employed to analyze the surface enhanced Raman scattering (SERS) spectroscopy of banned food additives, such as Sudan I dye and Rhodamine B in food, Malachite green residues in aquaculture fish. Multivariate qualitative analysis methods, using the combination of spectra preprocessing iteratively cubic spline fitting (ICSF) baseline correction with principal component analysis (PCA) and discriminant partial least squares (DPLS) classification respectively, are applied to investigate the effectiveness of SERS spectroscopy for predicting the class assignments of unknown banned food additives. PCA cannot be used to predict the class assignments of unknown samples. However, the DPLS classification can discriminate the class assignment of unknown banned additives using the information of differences in relative intensities. The results demonstrate that SERS spectroscopy combined with ICSF baseline correction method and exploratory analysis methodology DPLS classification can be potentially used for distinguishing the banned food additives in field of food safety.

To analyze existing evidence on the impact of two types of location restrictions on smoking: workplace bans and bans in hospitality settings, and to assess the extent to which they differentially affect subpopulations. A review of international studies on location restrictions on smoking published between 1990-2007. Although workplace smoking bans reduce exposure to second-hand smoke (SHS) at work, their effects on overall cigarette consumption and smoking prevalence may be uneven across the population. Bans in hospitality settings reduce SHS exposure among workers, but have potentially uneven effects based on the interactions between gender, socio-economic status (SES) and ethnicity. The unintended consequences of smoking bans are also more likely to be experienced by low SES groups. Although location restrictions on smoking reduce SHS exposure and may serve to positively impact smoking behaviours, there is preliminary evidence that they may have a reduced impact on subpopulations such as low-income groups, although further research is needed.

The temporal changes in the frequency and degree of imposex and tributyltin (TBT) levels in gastropod (Reishia clavigera) were evaluated in Jinhae Bay, 5 and 10 years after the total ban on TBT usage in South Korea. The frequency and degree of imposex decreased significantly after the ban, accompanied by an increase in the female-to-male ratio. The TBT concentrations in R. clavigera also decreased significantly after the ban. There were good correlations between the TBT concentration in rock shell and both the degree of imposex and the female-to-male ratio. The total TBT ban effectively reduced the TBT levels and the frequency and degree of imposex in R. clavigera. However, the current low exposure level in the study area is still sufficient to cause imposex in R. clavigera. More time is needed to reduce the TBT levels to levels that do not have adverse biological effects on R. clavigera.

Objective To examine childhood perfectionism in anorexia nervosa (AN) restricting (RAN), purging (PAN), and binge eating with or without purging (BAN) subtypes. Method The EATATE, a retrospective assessment of childhood perfectionism, and the Eating Disorder Inventory (EDI-2) were administered to 728 AN participants. Results EATATE responses revealed General Childhood Perfectionism, 22.3% of 333 with RAN, 29.2% of 220 with PAN, and 24.8% of 116 with BAN; School Work Perfectionism, 31.2% with RAN, 30.4% with PAN, and 24.8% with BAN; Childhood Order and Symmetry, 18.7% with RAN, 21.7% with PAN, and 17.8% with BAN; and Global Childhood Rigidity, 42.6% with RAN, 48.3% with PAN and 48.1% with BAN. Perfectionism preceded the onset of AN in all subtypes. Significant associations between EDI-2 Drive for Thinness and Body Dissatisfaction were present with four EATATE subscales. Discussion Global Childhood Rigidity was the predominate feature that preceded all AN subtypes. This may be a risk factor for AN. PMID:22488115

Many developed countries have banned the use of asbestos, but not the United States. There have, however, been multiple efforts in the US to establish strict exposure standards, to limit asbestos use, and to seek compensation through the courts for asbestos-injured workers' In consequence of these efforts, asbestos use has declined dramatically, despite the absence of a legally mandated ban. This manuscript presents a historical review of these efforts.

Predatory and scavenging birds may be exposed to high levels of lead when they ingest shot or bullet fragments embedded in the tissues of animals injured or killed with lead ammunition. Lead poisoning was a contributing factor in the decline of the endangered California condor population in the 1980s, and remains one of the primary factors threatening species recovery. In response to this threat, a ban on the use of lead ammunition for most hunting activities in the range of the condor in California was implemented in 2008. Monitoring of lead exposure in predatory and scavenging birds is essential for assessing the effectiveness of the lead ammunition ban in reducing lead exposure in these species. In this study, we assessed the effectiveness of the regulation in decreasing blood lead concentration in two avian sentinels, golden eagles and turkey vultures, within the condor range in California. We compared blood lead concentration in golden eagles and turkey vultures prior to the lead ammunition ban and one year following implementation of the ban. Lead exposure in both golden eagles and turkey vultures declined significantly post-ban. Our findings provide evidence that hunter compliance with lead ammunition regulations was sufficient to reduce lead exposure in predatory and scavenging birds at our study sites.

The Asbestos Ban in Korea from a Grassroots Perspective: Why Did It Occur?

In 2009, asbestos was finally banned in Korea, about 70 years after the first opening of asbestos mines under Japanese control. After having presented the history of asbestos industry, together with its regulations and health effects over time, we constructed narrative analyses of how the asbestos issue under the prevailing risk system was managed by whom and for what purpose, to provide context for the change. We could identify five different phases: laissez-faire, politico-technical, economic–managerial, health-oriented cultural, and human rights-based post-cultural risk systems. The changes leading to the asbestos ban evolved over different phases, and each phase change was necessary to reach the final ban, in that, without resolving the previous issues by examining different categories of potential alternatives, either the final ban was not possible or, even if instituted, could not be sustained. An asbestos ban could be introduced when all the alternatives to these issues, including legitimate political windows, economic rationalizations, health risk protections, and human rights sensitivities, were available. We think the alternatives that we had were not in perfect shape, but in more or less loosely connected forms, and hence we had to know how to build solidarities between different stakeholders to compensate for the imperfections.

A group of United Kingdom (UK) hospitals. To estimate the current smoking habits of health care professionals (HCPs) in a country with active tobacco control measures, and to record their attitudes to national and hospital tobacco bans. A cross-sectional survey of 500 HCPs. HCPs reported a lower rate of current smoking (7%) than the general population (24%). Doctors (2.6%) and medical students (3.8%) were less likely to be current smokers than both nurses (8.7%) and allied health professionals (10.9%, P < 0.001). The vast majority felt national legislation had been effective (88%) and well complied with (82%). Around a third of respondents believed the ban had led to a reduction in admissions for acute coronary syndrome. Almost all respondents were in favour of restrictions on smoking in health care premises. A higher proportion of UK doctors (69%) than nurses (52%) favoured a complete ban (odds ratio 2.01, 95% confidence interval 1.14-3.56). Self-reported smoking patterns in UK health professionals are lower than previously and compared to other industrialised and developing countries. Support for bans is very high, but differences remain in behaviour and especially attitudes to local bans according to professional status, although this gap is also narrowing.

The objective of this study was to examine hospital discharge data on 5 tobacco-related diagnoses before and after implementation of a smoking ban in a small Texas city. We compared hospital discharge rates for 2 years before and 2 years after implementation of the ban in the intervention city with discharge rates during the same time in a similar city with no ban. The discharge rates for blacks and whites combined declined significantly after the ban in the intervention city for acute myocardial infarction (MI) (rate ratio [RR], 0.74; 95% confidence interval [CI], 0.65-0.85) and for stroke or cerebrovascular accident (RR, 0.71; 95% CI, 0.62-0.82); discharge rates in the intervention city also declined significantly for chronic obstructive pulmonary disease (RR, 0.64; 95% CI, 0.54-0.75) and asthma (RR, 0.69; 95% CI, 0.52-0.91) for whites only. Discharge rates for 4 of 5 diagnoses in the control city did not change. Although postban reduction in acute MI is well documented, this is one of the first studies to show a racial disparity in health benefits and a decline in tobacco-related diagnoses other than acute MI after implementation of a city-wide smoking ban.

We examined how 'smoker' and 'non-smoker' self- and group-identities and socio-economic status (SES) may predict smoking behaviour and responses to antismoking measures (i.e., the Dutch smoking ban in hospitality venues). We validated a measure of responses to the smoking ban. Longitudinal online survey study with one-year follow-up (N = 623 at T1 in 2011; N = 188 at T2 in 2012) among daily smokers. Intention to quit, quit attempts and 'rejecting', 'victimizing', 'socially conscious smoking' and 'active quitting' responses to the smoking ban. Non-smoker identities are more important than smoker identities in predicting intention to quit, quit attempts and responses to the smoking ban, even when controlling for other important predictors such as nicotine dependence. Smokers with stronger non-smoker identities had stronger intentions to quit, were more likely to attempt to quit between measurements, and showed less negative and more positive responses to the smoking ban. The association between non-smoker self-identity and intention to quit was stronger among smokers with lower than higher SES. Antismoking measures might be more effective if they would focus also on the identity of smokers, and help smokers to increase identification with non-smoking and non-smokers.

Pulsed capacitors require high-recoverable energy-storage density (W rec ) and high energy-storage efficiency (η), which can be realized through the selection and adjustment of the composition. In this work, (1 - x)SrTiO 3 -x(0.95Bi 0.5 Na 0.5 TiO 3 -0.05BaAl 0.5 Nb 0.5 O 3 ) [(1 - x)ST-x(BNT-BAN)] ceramics were successfully prepared via the pressureless solid-state reaction method. The dielectric constant increases gradually with the introduction of BNT-BAN and obtains a maximum value of 3430 with the composition of 0.4ST-0.6(BNT-BAN) at 100 Hz, which is 10.39 times higher than that of the pure ST sample (∼330). Dispersive relaxor behaviors and ferroelectric performances can be enhanced with the introduction of BNT-BAN. The composition of 0.5ST-0.5(BNT-BAN) exhibits a high W rec of 1.89 J/cm 3 as well as a high η of 77%. Therefore, the (1 - x)ST-x(BNT-BAN) systems are candidate materials for pulsed capacitor applications.

Norway passed legislation banning smoking in restaurants, bars and other public spaces in 2004. This study tracks changes in hospitality workers' attitudes towards Norway's ban over three time points, using growth modelling analysis to examine predictors of attitude change. Participants were a national sample of 1525 bar and restaurant workers. Surveys were conducted, by phone or internet, one month before the ban's implementation and at 4 and 12 months thereafter. Exploratory principal components analysis of nine survey items revealed one primary attitude component. A latent growth model was fitted to the data to examine trajectories of attitude change and individual differences in rate of change. Respondents supported the ban before implementation and increased support at 4 months (p=0.021) and again at 12 months (p=0.001). Concern for one's job followed a quadratic trend, increasing at 4 months and decreasing at 12 months (p<0.001). All demographic categories were associated with attitude increase; rate of increase was greater for females than males. Two within-person variables--change in smoking status and change in job concern--strongly predicted (p<0.001) respondents' deviations from their predicted group trajectories, explaining over 70% of residual between-person slope variance. Norway's hospitality workers increased their support of the ban over its first year. The strong influence of the within-person variables leads to two primary policy recommendations. First, support should be provided to assist cessation efforts and prevent relapse. Second, informational campaigns should inform hospitality workers about evidence that smoking bans are not economic threats to the industry.

To evaluate the impact of the 2011 Scottish ban on multi-buy promotions of alcohol in retail stores. Difference-in-differences analysis was used to estimate the impact of the ban on the volume of alcohol purchased by Scottish households, compared with those in England and Wales, between January 2010 and June 2012. A total of 22 356 households in Scotland, England and Wales. Records of alcohol purchasing from each of four categories (beer and cider, wine, spirits and flavoured alcoholic beverages), as well as total volume of pure alcohol purchased. Controlling for general time trends and household heterogeneity, there was no significant effect of the multi-buy ban in Scotland on volume of alcohol purchased either for the whole population or for individual socio-economic groups. There was also no significant effect on those who were large pre-ban purchasers of alcohol. Most multi-buys were for beer and cider or for wine. The frequency of shopping trips involving beer and cider purchases increased by 9.2% following the ban (P < 0.01), while the number of products purchased on each trip decreased by 8.1% (P < 0.01). For wine, however, these effects were not significant. Banning multi-buy promotions for alcohol in Scotland did not reduce alcohol purchasing in the short term. Wider regulation of price promotion and price may be needed to achieve this. © 2013 The Authors. Addiction published by John Wiley & Sons Ltd on behalf of Society for the Study of Addiction.

Legal restrictions have contributed to the decline in smoking prevalence in several European countries. We investigated the impact of the Italian 2005 indoor smoking ban on the efficacy of counseling alone or in combination with bupropion for smoking cessation. Before and after the introduction of the ban (2001-2006), 550 smokers were enrolled in the smoking cessation program in Rome and were asked to choose between a 6-week group counseling therapy (GCT) given alone or in combination with 7 weeks of daily bupropion. Follow-up was completed 12, 26, and 52 weeks after the quit day. Due to the observational nature of the study, we used propensity scores to match 138 and 290 subjects (pre-/postban) in the bupropion- and GCT-only groups, respectively. Covariate balance in the two matched samples was adequate for all variables except "coffee consumption" in the GCT-only group. The regression adjusted odds ratios indicated that the introduction of the ban resulted in 52% reduced odds of continued smoking at 12 months among the GCT + bupropion group and 41% reduced odds in the GCT-only group. We observed that the ban was associated with both increased 12-month abstinence rates and motivation to quit. In a mediation analysis, we determined that the total effect of the smoking ban on the abstinence rate was reduced after controlling for motivation, which confirmed that motivation was a partial mediator. The introduction of an indoor smoking ban improved the efficacy of smoking cessation treatments by possibly providing a setting that increased the level of motivation to stop smoking.

To review systematically the literature on the economic impact of smoking bans in bars and restaurants and provide an estimate of the impact size using meta-analysis. Studies were identified by systematic database searches and screening references of reviews and relevant studies. Google and web-pages of tobacco control agencies were also searched. The review identified 56 studies using absolute sales, sales ratio or employment data and employing regression methods to evaluate the impact of smoking bans in the United States, Australia or in countries in South America or Europe. The meta-analysis included 39 comparable studies, with 129 cases identified based on the outcome measure, scope of the ban, type of establishment and geographical location. Methodological quality was assessed based on four pre-determined criteria. Study and case selection and data extraction were conducted independently by two researchers. Random-effects meta-analysis of all cases showed no associations between smoking bans and changes in absolute sales or employment. An increase in the share of bar and restaurant sector sales in total retail sales was associated with smoking bans [0.23 percentage-points; 95% confidence interval (CI) 0.08-0.375]. When cases were separated by business type (bars or restaurants or wider hospitality including bars and restaurants), some differential impacts emerged. Meta-analysis of the economic impact of smoking bans in hospitality sector showed overall no substantial economic gains or losses. Differential impacts were observed across individual business types and outcome variable, but at aggregate level these appear to balance out. © 2014 Society for the Study of Addiction.

Although most countries now have at least some restrictions on tobacco marketing, the tobacco industry meet these restrictions by re-allocating expenditure to unregulated channels, such as at point-of-purchase. Longitudinal data from 10 Canadian provinces in the International Tobacco Control Survey was analysed to examine adult smokers' support for a ban on tobacco advertising and displays in stores and whether this support is associated with noticing either advertising or displays in stores, and quit intentions, over time. In total, there were 4580 respondents in wave 5 (October 2006 to February 2007), wave 6 (September 2007 to February 2008) and wave 7 (October 2008 to June 2009). The surveys were conducted before, during and in some cases after the implementation of display bans in most Canadian provinces and territories. Smokers in all provinces showed strong support for a ban on tobacco displays over the study period. Levels of support for an advertising and display ban were comparable between Canadian provinces over time, irrespective of whether they had been banned or not. Noticing tobacco displays and signs in-store was demonstrably less likely to predict support for display (OR=0.73, p=0.005) and advertising (OR=0.78, p=0.02) ban, respectively. Smokers intending to quit were more likely to support advertising and display bans over time. This study serves as a timely reminder that the implementation of tobacco control measures, such as the removal of tobacco displays, appear to sustain support among smokers, those most likely to oppose such measures.

The Maharashtra government has banned the production, sale, distribution and storage of gutka, and pan masala in the Maharashtra State due to the increasing burden of cancer and reproductive health problems attributable to the use of these products. In view of this, it is important to understand the way producers', sellers' and users' are adapting to the ban. During the two months following the ban (July 19 th through Sept 30, 2012), a research team studying smokeless tobacco use and promotion in a low income community of Mumbai conducted rapid surveillance to assess the impact of the ban in the study community. Assessment involved documenting new points of sale, informal observations of tobacco use, and interviews with thirteen shop owners and eight gutka users'. Overall changes in accessibility, availability, patterns of use of tobacco products, perception of ban, social norms and surveillance activities were assessed. Tobacco companies were marketing new products that resembled gutka, under similar brand logos. Surveillance, financial and social cost of selling gutka or using it in public have had an immediate effect on reducing local supply, demand and use and increasing stigma associated with its use. There was an increased recognition of ill-effects of gutka on cancer among sellers' but not overall. To reduce the overall consumption of tobacco in the community, it is critical to include programs that create awareness about effects of smokeless tobacco on health and sustain surveillance levels. This would maintain requirements of the ban, and sustain limits on accessibility, availability and use of these products in the community and other similar communities.

Secondhand smoke exposure (SHSe) threatens fragile infants discharged from a neonatal intensive care unit (NICU). Smoking practices were examined in families with a high respiratory risk infant (born at very low birth weight; ventilated > 12 hr) in a Houston, Texas, NICU. Socioeconomic status, race, and mental health status were hypothesized to be related to SHSe and household smoking bans. Data were collected as part of The Baby's Breath Project, a hospital-based SHSe intervention trial targeting parents with a high-risk infant in the NICU who reported a smoker in the household (N = 99). Measures of sociodemographics, smoking, home and car smoking bans, and depression were collected. Overall, 26% of all families with a high-risk infant in the NICU reported a household smoker. Almost half of the families with a smoker reported an annual income of less than $25,000. 46.2% of families reported having a total smoking ban in place in both their homes and cars. Only 27.8% families earning less than $25,000 reported having a total smoking ban in place relative to almost 60% of families earning more (p < .01). African American and Caucasian families were less likely to have a smoking ban compared with Hispanics (p < .05). Mothers who reported no smoking ban were more depressed than those who had a household smoking ban (p < .02). The most disadvantaged families were least likely to have protective health behaviors in place to reduce SHSe and, consequently, are most at-risk for tobacco exposure and subsequent tobacco-related health disparities. Innovative SHSe interventions for this vulnerable population are sorely needed.

Background: Since 2006, banning smoking in cars with children has become a rapidly growing tobacco control policy. However, to date, there have been few studies examining support and correlates of support for car smoking bans, and none of the existing studies have been international in nature. We conducted such a study among smokers in four countries. Methods: 6716 adult current smokers from the 2007 Wave of the International Tobacco Control Four Country Survey, a nationally representative, longitudinal cohort telephone survey of smokers in the USA, Canada, UK and Australia. Controlling for demographics, heaviness of smoking, smoking health knowledge/beliefs and quit intentions, we compared support and correlates of support for banning smoking in cars with children across the four countries. Results: The majority of smokers supported banning smoking in cars with children. Support was highest in Australia (83%), followed by the UK (75%) and Canada (74%); support was lower—but still high—in the USA (60%). Support was highest among smokers who: had stronger quit intentions, were lighter smokers, had lower education, had no children in the home, believed that cigarette smoke is dangerous to non-smokers and could cause asthma in children, and were concerned about modelling smoking to children. Conclusions: These findings indicate that a majority of smokers in the four countries support banning smoking in cars with children, and lend support to banning smoking in cars with children. Additionally, they suggest that support may be increased by educating smokers about the dangers of cigarette smoke exposure. PMID:20630910

Background Although most countries now have at least some restrictions on tobacco marketing, the tobacco industry meet these restrictions by re-allocating expenditure to unregulated channels, such as at point-of-purchase. Methods Longitudinal data from 10 Canadian provinces in the International Tobacco Control Survey was analysed to examine adult smokers’ support for a ban on tobacco advertising and displays in stores and whether this support is associated with noticing either advertising or displays in stores, and quit intentions, over time. In total, there were 4580 respondents in wave 5 (October 2006 to February 2007), wave 6 (September 2007 to February 2008) and wave 7 (October 2008 to June 2009). The surveys were conducted before, during and in some cases after the implementation of display bans in most Canadian provinces and territories. Results Smokers in all provinces showed strong support for a ban on tobacco displays over the study period. Levels of support for an advertising and display ban were comparable between Canadian provinces over time, irrespective of whether they had been banned or not. Noticing tobacco displays and signs in-store was demonstrably less likely to predict support for displays (OR=0.73, p=0.005) and advertising (OR=0.78, p=0.02) ban, respectively. Smokers intending to quit were more likely to support advertising and display bans over time. Conclusion This study serves as a timely reminder that the implementation of tobacco control measures, such as the removal of tobacco displays, appear to sustain support among smokers, those most likely to oppose such measures.

Despite the great progress made towards smoke-free environments, only 9% of countries worldwide mandate smoke-free restaurants and bars. Smoking was generally not regulated in restaurants and bars in China before 2008. This study was designed to examine the public attitudes towards banning smoking in these places in China. A convenience sample of 814 restaurants and bars was selected in five Chinese cities and all owners of these venues were interviewed in person by questionnaire in 2007. Eighty six percent of current nonsmoking subjects had at least one-day exposure to secondhand smoke (SHS) at work in the past week. Only 51% of subjects knew SHS could cause heart disease. Only 17% and 11% of subjects supported prohibiting smoking completely in restaurants and in bars, respectively, while their support for restricting smoking to designated areas was much higher. Fifty three percent of subjects were willing to prohibit or restrict smoking in their own venues. Of those unwilling to do so, 82% thought smoking bans would reduce revenue, and 63% thought indoor air quality depended on ventilation rather than smoking bans. These results showed that there was support for smoking bans among restaurant or bar owners in China despite some knowledge gaps. To facilitate smoking bans in restaurants and bars, it is important to promote health education on specific hazards of SHS, provide country-specific evidence on smoking bans and hospitality revenues, and disseminate information that restricting smoking and ventilation alone cannot eliminate SHS hazards.

Secondhand smoke (SHS) in US casinos is common, but little is known about the residue of tobacco smoke pollutants left behind in dust and on surfaces, commonly referred to as thirdhand smoke (THS). We examined SHS and THS pollution and exposure before and during a casino smoking ban and after smoking resumed. A casino was visited nine times over a 15-month period to collect dust, surface and air samples in eight locations. Finger wipe and urine samples were collected from non-smoking confederates before and after a 4-hour casino visit. Samples were analysed for markers of SHS and THS pollution and exposure. Exceptionally high levels of THS were found in dust and on surfaces. Although the smoking ban led to immediate improvements in air quality, surface nicotine levels were unchanged and remained very high for the first month of the smoking ban. Surface nicotine decreased by 90% after 1 month (P<0.01), but nicotine and tobacco-specific nitrosamines in dust decreased more slowly, declining by 90% only after 3 months (P<0.01). Exposure was significantly reduced after the ban, but the benefits of the ban were reversed after smoking resumed. Long-term smoking in a casino creates deep THS reservoirs that persist for months after a smoking ban. A complete smoking ban immediately improves air quality and significantly reduces exposure to SHS and THS. However, THS reservoirs contribute to continued low-level exposure to toxicants. To accelerate the effect of smoking bans, remediation efforts should address specific THS reservoirs, which may require intensive cleaning as well as replacement of carpets, furniture and building materials. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Challenges for the smoking ban in Israeli pubs and bars: analysis guided by the behavioral ecological model

PubMed Central

2012-01-01

Background The latest amendment to the ban on smoking in public places in Israel was implemented in 2007, adding pubs and bars (P&B) to the list of public places in which smoking is prohibited. However, smoking in most P&B continued. The aim of the study was to identify the theoretically plausible reasons for the partial success of a public ban on smoking in P&B settings. Explanations provided by P&B owners were interpreted as probable causal factors based on the Behavioral Ecological Model (BEM). Methods Qualitative interviews were performed with 36 P&B owners in Tel-Aviv and 18 Israeli towns and cities of various population size. Results P&B owners reported a variety of situational factors (i.e., contingencies) and reinforcers as likely explanations of the partial failure of the legislated ban on smoking in public places, particularly P&B. The major reinforcers for non-adherence with the law were no or low frequency of inspections and low penalties from authorities. P&B owners also feared loss of customers and revenue if bans were enforced in their own establishment but not in competing establishments. Finally, owners reported social norms prevailing among some Israeli patrons supporting smoking in P&B settings, in part to express opposition to the new law. Conclusions Qualitative assessment can uncover probable social situations that operate to prevent greater adherence to smoking bans. The results warrant confirmation by quantitative analyses. Policies with mandated inspections and penalty requirements that are implemented in all bars without prejudice could lead to greater adherence to smoking bans. Positive reinforcing consequences that encourage adherence (such as publicity and support from non-smokers) would be more likely to generate both greater adherence to the policy and good will toward the government. Principles of behavior outlined in the BEM offer guidance for designing quantitative confirmation analyses of future bans. PMID:22913392

There are potential health risks associated with the use of early weaning to prevent mother-to-child transmission of human immunodeficiency virus (HIV) in resource-poor settings. Our objective was to examine growth and nutrient inadequacies among a cohort of children weaned early. Children participating in the Breastfeeding Antiretrovirals and Nutrition (BAN) Study in Lilongwe, Malawi, had HIV-infected mothers, were weaned at 6 months and fed LNS until 12 months. 40 HIV-negative, BAN-exited children were compared with 40 HIV-negative, community children matched on age, gender and local health clinic. Nutrient intake was calculated from 24-h dietary recalls collected from BAN-exited children. Anthropometric measurements were collected from BAN-exited and matched community children at 15-16 months, and 2 months later. Longitudinal random effects sex-stratified models were used to evaluate anthropometric differences between the two groups. BAN-exited children consumed adequate energy, protein and carbohydrates but inadequate amounts of fat. The prevalence of inadequate micronutrient intakes were: 46% for vitamin A; 20% for vitamin B6; 69% for folate; 13% for vitamin C; 19% for iron; 23% for zinc. Regarding growth, BAN-exited girls gained weight at a significantly lower rate {0.02 g kg(-1) per day [95% confidence interval (CI): 0.01, 0.03]} than their matched comparison [0.05 g kg(-1) per day (95% CI: 0.03, 0.07)]; BAN girls grew significantly slower [0.73 cm month(-1) (95% CI: 0.40,1.06)] than their matched comparison (1.55 cm month(-1) [95% CI: 0.98, 2.12]). Among this sample of BAN-exited children, early weaning was associated with dietary deficiencies and girls experienced reduced growth velocity. In resource-poor settings, HIV prevention programmes must ensure that breastfeeding stop only once a nutritionally adequate and safe diet without breast milk can be provided. © 2011 Blackwell Publishing Ltd.

Unexpected Diversity of Feral Genetically Modified Oilseed Rape (Brassica napus L.) Despite a Cultivation and Import Ban in Switzerland

2014-01-01

Despite cultivation and seed import bans of genetically modified (GM) oilseed rape (Brassica napus L.), feral GM plants were found growing along railway lines and in port areas at four sites in Switzerland in 2011 and 2012. All GM plants were identified as glyphosate-resistant GM event GT73 (Roundup Ready, Monsanto). The most affected sites were the Rhine port of Basel and the St. Johann freight railway station in Basel. To assess the distribution and intra- and interspecific outcrossing of GM oilseed rape in more detail, we monitored these two sites in 2013. Leaves and seed pods of feral oilseed rape plants, their possible hybridization partners and putative hybrid plants were sampled in monthly intervals and analysed for the presence of transgenes by real-time PCR. Using flow cytometry, we measured DNA contents of cell nuclei to confirm putative hybrids. In total, 2787 plants were sampled. The presence of GT73 oilseed rape could be confirmed at all previously documented sampling locations and was additionally detected at one new sampling location within the Rhine port. Furthermore, we found the glufosinate-resistant GM events MS8xRF3, MS8 and RF3 (all traded as InVigor, Bayer) at five sampling locations in the Rhine port. To our knowledge, this is the first time that feral MS8xRF3, MS8 or RF3 plants were detected in Europe. Real-time PCR analyses of seeds showed outcrossing of GT73 into two non-GM oilseed rape plants, but no outcrossing of transgenes into related wild species was observed. We found no hybrids between oilseed rape and related species. GM plants most frequently occurred at unloading sites for ships, indicating that ship cargo traffic is the main entry pathway for GM oilseed rape. In the future, it will be of major interest to determine the source of GM oilseed rape seeds. PMID:25464509

Many developed countries have banned the use of asbestos, but not the United States. There have, however, been multiple efforts in the US to establish strict exposure standards, to limit asbestos use, and to seek compensation through the courts for asbestos-injured workers’. In consequence of these efforts, asbestos use has declined dramatically, despite the absence of a legally mandated ban. This manuscript presents a historical review of these efforts. PMID:29072598

Impact of the smoking ban on the volume of bar sales in Ireland: evidence from time series analysis.

This paper is the first to estimate the economic impact of a comprehensive smoking ban in all enclosed public places of work, on bars in Ireland. The demand in bars, represented by a monthly index of sales volume, is explained by relative prices in bars, prices of alcohol sold in off-licences and the aggregate retail sales (ARS) as a proxy for general economic activity and incomes. The smoking ban is included into the model as a step dummy and the modelling is done using ARIMAX strategy. The results show a reduction in the volume of sales in bars by -4.6% (p<0.01) following the ban. Copyright © 2011 John Wiley & Sons, Ltd.

Sugar-sweetened beverage (SSB) consumption is linked to increased weight and obesity in children and remains the major source of added sugar in the typical US diet across all age groups. In an effort to improve the nutritional offerings for patients and employees within our institution, Nationwide Children’s Hospital in Columbus, Ohio, implemented an SSB ban in 2011 in all food establishments within the hospital. In this report, we describe how the ban was implemented. We found that an institutional SSB ban altered beverage sales without revenue loss at nonvending food locations. From a process perspective, we found that successful implementation requires excellent communication and bold leadership at several levels throughout the hospital environment. PMID:25121811

Prison smoking bans are increasingly common. It is important to consider how those who are incarcerated respond to these bans and to the subsequent development of contraband tobacco markets. Since there are high rates of smoking in individuals who become incarcerated, along with high rates of chronic illnesses that are exacerbated by smoking, it is critical to examine whether there are health promoting changes in perceptions of and intentions toward smoking and other health behaviors that can be maintained on release to the community. Interviews with incarcerated men experiencing a prison smoking ban revealed their responses to being smoke-free, reactions to the presence of contraband smoking, and the influences of this experience on their intentions to smoke following release.

Signature molecular descriptor : advanced applications.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Visco, Donald Patrick, Jr.

In this work we report on the development of the Signature Molecular Descriptor (or Signature) for use in the solution of inverse design problems as well as in highthroughput screening applications. The ultimate goal of using Signature is to identify novel and non-intuitive chemical structures with optimal predicted properties for a given application. We demonstrate this in three studies: green solvent design, glucocorticoid receptor ligand design and the design of inhibitors for Factor XIa. In many areas of engineering, compounds are designed and/or modified in incremental ways which rely upon heuristics or institutional knowledge. Often multiple experiments are performed andmore » the optimal compound is identified in this brute-force fashion. Perhaps a traditional chemical scaffold is identified and movement of a substituent group around a ring constitutes the whole of the design process. Also notably, a chemical being evaluated in one area might demonstrate properties very attractive in another area and serendipity was the mechanism for solution. In contrast to such approaches, computer-aided molecular design (CAMD) looks to encompass both experimental and heuristic-based knowledge into a strategy that will design a molecule on a computer to meet a given target. Depending on the algorithm employed, the molecule which is designed might be quite novel (re: no CAS registration number) and/or non-intuitive relative to what is known about the problem at hand. While CAMD is a fairly recent strategy (dating to the early 1980s), it contains a variety of bottlenecks and limitations which have prevented the technique from garnering more attention in the academic, governmental and industrial institutions. A main reason for this is how the molecules are described in the computer. This step can control how models are developed for the properties of interest on a given problem as well as how to go from an output of the algorithm to an actual chemical structure. This report provides details on a technique to describe molecules on a computer, called Signature, as well as the computer-aided molecule design algorithm built around Signature. Two applications are provided of the CAMD algorithm with Signature. The first describes the design of green solvents based on data in the GlaxoSmithKline (GSK) Solvent Selection Guide. The second provides novel non-steroidal glucocorticoid receptor ligands with some optimally predicted properties. In addition to using the CAMD algorithm with Signature, it is demonstrated how to employ Signature in a high-throughput screening study. Here, after classifying both active and inactive inhibitors for the protein Factor XIa using Signature, the model developed is used to screen a large, publicly-available database called PubChem for the most active compounds.« less

2008-08-01

This study attempted to identify changes in exposure to environmental tobacco smoke, as well as symptoms and attitudes among hospitality workers after the introduction of extended smoke-free workplace legislation. A total of 37 volunteers working in bingo halls and casinos (gaming workers) and 54 bars and restaurant employees (other workers) in nine Swedish communities participated in the study. Altogether 71 of 91 persons (14 daily smokers and 57 nonsmokers) participated in both the pre-ban baseline survey and the follow-up 12 months after the ban. Exposure to environmental tobacco smoke, smoking habits, respiratory and sensory symptoms, and attitudes towards the ban were recorded, and spirometry was carried out. The frequency of reported respiratory and sensory symptoms was approximately halved among the nonsmokers in both occupational groups after the introduction of the ban. Initially 87% had exposure to environmental tobacco smoke that was over the nicotine cut-off level chosen to identify possible health risk ( <0.5 microg/m3) while, after the ban, it was only 22%, a relative risk of 0.25 (95% confidence interval 0.15-0.41). The risk decreased in both occupational groups, but gaming workers experienced the highest pre-ban exposure levels. Attitudes towards the legislation were largely positive, particularly after the ban. However, there was no notable change in lung function, and there was no notable reduction in the number of cigarettes consumed by smokers. The introduction of smoke-free legislation was associated with a substantial reduction in respiratory and sensory symptoms, as well as reduced exposure to environmental tobacco smoke at work, particularly among gaming workers.

Effects of Maryland's law banning Saturday night special handguns on crime guns

Vernick, J.; Webster, D.; Hepburn, L.

1999-01-01

Objectives—To determine the effects of a 1988 Maryland law that banned "Saturday night special" handguns on the types of guns used in crime. To determine if controls on the lawful market for handguns affect the illegal market as well. Setting—Baltimore, Maryland, and 15 other US cities participating in a crime gun tracing project. Methods—Cross sectional comparison of the proportion of crime guns that are banned by the Maryland law, comparing Baltimore, MD with 15 other cities outside of Maryland. Multivariate linear regression analysis to determine if observed differences between Baltimore and 15 other cities are explained by demographic or regional differences among the cities rather than Maryland's law. Results—Among crime guns, a gun banned by Maryland's law is more than twice as likely (relative risk (RR) 2.3, 95% confidence interval (CI) 2.0 to 2.5) to be the subject of a crime gun trace request in 15 other cities combined, than in Baltimore. Among homicide guns, a crime especially relevant for public safety, a comparable difference (RR 2.1, 95% CI 1.1 to 4.2) was observed. The proportion of Baltimore's crime guns that are banned is 12 percentage points lower than would be expected based on its demographic and regional characteristics alone. Among crime guns purchased after 1990, a much smaller proportion in Baltimore are banned models than in 15 other cities. Conclusions—Maryland's law has reduced the use of banned Saturday night specials by criminals in Baltimore. Contrary to the claims of some opponents of gun control laws, regulation of the lawful market for firearms can also affect criminals. PMID:10628912

Perceptions of parental smoking and sociodemographic factors associated with the adoption of home smoking bans among parents of school-aged children.

Although public smoking restrictions have been implemented, children are still exposed to household smoking. Parental smoking is the main source of children's exposure to secondhand smoke. This study was conducted to examine the factors associated with parents' adoption of home smoking bans. A cross-sectional study was conducted using a self-administered questionnaire to collect data from 768 parents of school-aged children in Taiwan. The home smoking restriction status, parents' perceptions of smoking in the presence of children and its influences, and parents' sociodemographic characteristics were assessed. Hierarchical logistic regression analysis was used to determine the best-fit model. More than 80% of the parents agreed with home smoking bans, whereas only approximately 26% of the parents actually restricted smoking at home completely. The crude odds ratios showed that parents who perceived the influence of parental smoking on children to be negative were more likely to adopt home smoking bans. Hierarchical logistic regression revealed factors associated with the adoption of home smoking bans, including a higher education level and older age of parents, a family composed of nonparent adults, and opposition to parental smoking in the presence of children. Children's health is a major concern for parents considering home smoking bans. Helping parents clarify misunderstandings regarding parental smoking, emphasizing the adverse effects of children's exposure to parental smoking, suggesting healthy substitutes for smoking, and providing effective strategies for maintaining a smoke-free home can motivate families to adopt home smoking bans. © The Author 2014.

Northwest directed slip from the southern San Andreas Fault is transferred to the Mission Creek, Banning, and Garnet Hill fault strands in the northwestern Coachella Valley. How slip is partitioned between these three faults is critical to southern California seismic hazard estimates but is poorly understood. In this paper, we report the first slip rate measured for the Banning fault strand. We constrain the depositional age of an alluvial fan offset 25 ± 5 m from its source by the Banning strand to between 5.1 ± 0.4 ka (95% confidence interval (CI)) and 6.4 + 3.7/−2.1 ka (95% CI) using U-series dating of pedogenic carbonate clast coatings and 10Be cosmogenic nuclide exposure dating of surface clasts. We calculate a Holocene geologic slip rate for the Banning strand of 3.9 + 2.3/−1.6 mm/yr (median, 95% CI) to 4.9 + 1.0/−0.9 mm/yr (median, 95% CI). This rate represents only 25–35% of the total slip accommodated by this section of the southern San Andreas Fault, suggesting a model in which slip is less concentrated on the Banning strand than previously thought. In rejecting the possibility that the Banning strand is the dominant structure, our results highlight an even greater need for slip rate and paleoseismic measurements along faults in the northwestern Coachella Valley in order to test the validity of current earthquake hazard models. In addition, our comparison of ages measured with U-series and 10Be exposure dating demonstrates the importance of using multiple geochronometers when estimating the depositional age of alluvial landforms.

Smoking bans in bars and restaurants have been shown to improve worker health and reduce hospital admissions for acute myocardial infarction. Several studies have also reported improved indoor air quality, although these studies generally used single visits before and after a ban for a convenience sample of venues. The primary objective of this study was to provide detailed time-of-day and day-of-week secondhand smoke-exposure data for representative bars and restaurants in Minnesota. This study improved on previous approaches by using a statistically representative sample of three venue types (drinking places, limited-service restaurants, and full-service restaurants), conducting repeat visits to the same venue prior to the ban, and matching the day of week and time of day for the before- and after-ban monitoring. The repeat visits included laser photometer fine particulate (PM₂.₅) concentration measurements, lit cigarette counts, and customer counts for 19 drinking places, eight limited-service restaurants, and 35 full-service restaurants in the Minneapolis/St. Paul metropolitan area. The more rigorous design of this study provides improved confidence in the findings and reduces the likelihood of systematic bias. The median reduction in PM₂.₅ was greater than 95% for all three venue types. Examination of data from repeated visits shows that making only one pre-ban visit to each venue would greatly increase the range of computed percentage reductions and lower the statistical power of pre-post tests. Variations in PM₂.₅ concentrations were found based on time of day and day of week when monitoring occurred. These comprehensive measurements confirm that smoking bans provide significant reductions in SHS constituents, protecting customers and workers from PM₂.₅ in bars and restaurants.

Introduction: This Canadian study examines the prevalence of smoking restrictions in homes before and after the implementation of a public smoking ban, and their relation to tobacco use and cessation among a cohort of smokers. Methods: Data were from a longitudinal cohort study of 1,058 smokers in the province of Québec, Canada. Baseline data were collected through a population-based survey conducted 1 month before the implementation of the smoking ban with a representative sample of smokers. Follow-up data were collected 18 months after the ban with a response rate of 68%. Logistic regressions, paired t tests and chi-square statistics were used to examine the factors associated with smoking restrictions in homes, cigarette consumption, and quit attempts. Results: Many smokers imposed partial or full smoking restrictions in their homes but proportions of smoke-free homes did not change significantly between baseline and follow-up. The presence of young children and nonsmokers significantly predicted full smoking restriction in the home. Knowledge about risks associated with exposure to secondhand smoke (SHS) and skepticism about the efficacy of methods to reduce exposure in the home also predicted maintenance of voluntary smoking restrictions in homes. The uptake of smoke-free homes was not associated with the quantity of cigarettes smoked or quit attempts. Conclusions: No significant change in home smoking bans was found 18 months after implementation of a public smoking ban. There remains a need for efforts to better inform smokers about health risks from exposure to SHS in homes and the reality that strategies other than a total smoking ban inside the home are ineffective.

Objective A prospective evaluation of the effect of 2012 point-of-sale (PoS) display ban in supermarkets in England on perceived exposure to PoS displays, and on changes in susceptibility and smoking uptake among young people. Design Cohort study. Settings Seven schools in Nottinghamshire, England. Participants 1035 11–16-year-old school children. Primary and secondary outcome measures Changes in reported exposure to PoS displays before and after prohibition, and the association between exposure to and awareness of PoS displays and change in susceptibility to smoking and smoking status between 2011 and 2012 (before the ban) and 2012 and 2013 (after the ban). Results The proportion of children noticing tobacco PoS displays in supermarkets most or every time they visited a shop changed little between 2011 and 2012 (59.6% (95% CI 56.6% to 62.6%) and 58.8% (95% CI 55.8% to 61.8%), respectively); but decreased by about 13 percentage points to 45.7% (95% CI 42.7% to 48.7%) in 2013, after the ban. However, after adjusting for confounders, implementation of the first stage of the PoS ban in 2012 did not result in significant changes in the relation between susceptibility to smoking and smoking status and exposure to and awareness of PoS displays. Conclusions Prohibition of PoS in large supermarkets resulted in a decline in the proportion of young people noticing PoS displays in large shops, but little or no change in smoking uptake or susceptibility. It remains to be seen whether extension of the PoS ban to all shops in 2015 has a more marked effect. PMID:28115330

Background Existing evidence on the effects of smoke-free policies on respiratory diseases is scarce and inconclusive. Spain enacted two consecutive smoke-free regulations: a partial ban in 2006 and a comprehensive ban in 2011. We estimated their impact on hospital admissions via emergency departments for chronic obstructive pulmonary disease (COPD) and asthma. Methods Data for COPD (ICD-9 490–492, 494–496) came from 2003–2012 hospital admission records from the fourteen largest provinces of Spain and from five provinces for asthma (ICD-9 493). We estimated changes in hospital admission rates within provinces using Poisson additive models adjusted for long-term linear trends and seasonality, day of the week, temperature, influenza, acute respiratory infections, and pollen counts (asthma models). We estimated immediate and gradual effects through segmented-linear models. The coefficients within each province were combined through random-effects multivariate meta-analytic models. Results The partial ban was associated with a strong significant pooled immediate decline in COPD-related admission rates (14.7%, 95%CI: 5.0, 23.4), sustained over time with a one-year decrease of 13.6% (95%CI: 2.9, 23.1). The association was consistent across age and sex groups but stronger in less economically developed Spanish provinces. Asthma-related admission rates decreased by 7.4% (95%CI: 0.2, 14.2) immediately after the comprehensive ban was implemented, although the one-year decrease was sustained only among men (9.9%, 95%CI: 3.9, 15.6). Conclusions The partial ban was associated with an immediate and sustained strong decline in COPD-related admissions, especially in less economically developed provinces. The comprehensive ban was related to an immediate decrease in asthma, sustained for the medium-term only among men. PMID:28542337

Has the tobacco industry evaded the FDA's ban on ‘Light’ cigarette descriptors?

PubMed Central

Connolly, Gregory N; Alpert, Hillel R

2014-01-01

Background Under the Family Smoking Prevention and Tobacco Control Act (FSPTCA), the Food and Drug Administration (FDA) banned the use of “Lights” descriptors or similar terms on tobacco products that convey messages of reduced risk. Manufacturers eliminated terms explicitly stated and substituted colour name descriptors corresponding to the banned terms. This paper examines whether the tobacco industry complied with or circumvented the law and potential FDA regulatory actions. Methods Philip Morris retailer manuals, manufacturers' annual reports filed with the Massachusetts Department of Public Health, a national public opinion survey, and market-wide cigarette sales data were examined. Results Manufacturers substituted “Gold” for “Light” and “Silver” for “Ultra-light” in the names of Marlboro sub-brands, and “Blue”, “Gold”, and “Silver” for banned descriptors in sub-brand names. Percent filter ventilation levels, used to generate the smoke yield ranges associated with “Lights” categories, appear to have been reassigned to the new colour brand name descriptors. Following the ban, 92% of smokers reported they could easily identify their usual brands, and 68% correctly named the package colour associated with their usual brand, while sales for “Lights” cigarettes remained unchanged. Conclusions Tobacco manufacturers appear to have evaded a critical element of the FSPTCA, the ban on misleading descriptors that convey reduced health risk messages. The FPSTCA provides regulatory mechanisms, including banning these products as adulterated (Section 902). Manufacturers could then apply for pre-market approval as new products and produce evidence for FDA evaluation and determination whether or not sales of these products are in the public health interest.

2018-05-31

In the USA, menthol cigarettes are associated with smoking initiation and decreased likelihood of cessation, particularly for low-income and non-White populations. Local ordinances to restrict menthol cigarette sales are an emergent policy option. In July 2016, Chicago, Illinois became the first major US city to ban menthol cigarette sales within 500 feet of schools. This study assessed ban compliance in June 2017. We randomly selected 100 of 154 stores within 500 feet of a high school. Ninety stores were included in the analysis, excluding permanently closed stores or stores that did not sell tobacco prior to the ban. Compliance was determined by whether a menthol cigarette pack was purchased. We also assessed presence of menthol cigarette replacement packs. Multivariable logistic regression modelled compliance by store type, school (distance to high school, school type) and neighbourhood-level factors (poverty level, proportion of non-White residents). Compliance rate was 57% (weighted, n=53) and no replacement packs were observed. Non-compliant stores were more likely to advertise menthol cigarettes, but ads were present in eight compliant stores. Gas stations had 81% lower odds (OR=0.19, 95% CI 0.06 to 0.58) of complying with the menthol cigarette ban compared with larger/chain stores. School-level and neighbourhood factors were not associated with compliance. The poor compliance observed with Chicago's partial menthol cigarette ban highlights the need for comprehensive efforts. Optimising local resources to target enforcement efforts in gas stations could improve compliance. Ordinances that also restrict advertising could potentially enhance ban impact by reducing exposure to product and promotions. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Thailand is internationally renowned for its stringent tobacco control measures. In Thailand, a regulation banning smoking in air-conditioned hotel lobbies was issued in late 2006, causing substantial apprehension within the hospitality industry. A survey of tourists' attitudes toward the ban was conducted. A cross-sectional survey of 5550 travellers staying in various hotels in Bangkok, Surat Thani, Phuket, Krabi and Songkhla provinces, October 2005 to December 2006. Travellers aged 15 years or older with a check-in duration of at least one day and willing to complete the questionnaire were requested by hotel staff to fill in the 5-minute questionnaire at check-in or later at their convenience. Secondhand cigarette smoke was recognised as harmful to health by 89.7% of respondents. 47.8% of travellers were aware of the Thai regulation banning smoking in air-conditioned restaurants. 80.9% of the respondents agreed with the ban, particularly female non-smokers. 38.6% of survey respondents indicated that they would be more likely to visit Thailand again because of the regulation, 53.4% that the regulation would not affect their decision and 7.9% that they would be less likely to visit Thailand again. Banning smoking in air-conditioned hotel lobbies in Thailand is widely supported by tourists. Enforcement of the regulation is more likely to attract tourists than dissuade them from holidaying in Thailand.

Little research has focused on women's exposure to secondhand smoke (SHS) in LMICs, local perceptions of SHS risk to women and children, and women's attempts to limit exposure to tobacco smoke in their households. This paper describes a community based survey in Indonesia that investigated these issues as one step in a movement to initiate community wide household smoking bans. The survey found high levels of exposure to SHS, high levels of awareness among both women and men that SHS placed women and children at risk for illness, a very low percentage of households having indoor smoking rules, great interest on the part of women to participate in a communitywide ban, and a promising level of male smoker agreement to comply with such a ban. Women expressed a low sense of self efficacy in individually getting their husbands to quit smoking in their homes, but a strong sense of collective efficacy that husbands might agree to a well-publicized and agreed-upon community household smoking ban. Men and women expressed concern about the social risk of asking guests not to smoke in their homes without a communitywide ban and visible displays communicating their participation in this movement. The smoke free initiative described requires the participation of doctors in community education programs, and is attempting to introduce household smoking bans as a way of turning tobacco control into a family health and not just a smokers' health issue.

To evaluate the effect of a smoking ban in high schools on smoking behaviour among Chilean students. We conducted an interrupted time-series analysis, using repeated cross-sectional data from Chile's school population survey (2000-2011) for high-school students aged 12-18 years and a control group of persons aged 19-24 years. Poisson regression models were used to assess trends in smoking behaviour before and after the policy changes. The outcome measures were self-reported smoking prevalence (any smoking in the past month) and high frequency of smoking (smoking 15 days or more per month). From 2005 to 2011, the prevalence of smoking declined among high-school students by 6.8% per year compared with 3.6% decline per year in the control group. The decline in the target group was 2.9% (95% confidence interval, CI: 0.18 to 5.00) greater. We estimated that 5-6 years after enforcing the law, smoking prevalence among high-school students was 13.7% lower as a result of the ban. The impact of the smoking ban was primarily driven by declines in smoking prevalence among students in grades 8 to 10. The smoking ban did not significantly alter the frequency of smoking. The 2005 school smoking ban reduced smoking prevalence among younger high-school students in Chile. Further interventions targeting older individuals and frequent smokers may be needed.

To examine social-cognitive change associated with behavior change after the introduction of a smoke-free public places policy. Adults (N = 583) who use public houses licensed to sell alcohol (pubs) completed questionnaires assessing alcohol and tobacco consumption and social-cognitive beliefs 2 months prior to the introduction of the smoking ban in England on July 1, 2007. Longitudinal follow-up (N = 272) was 3 months after the introduction of the ban. Social-cognitive beliefs, daily cigarette consumption, and weekly alcohol consumption. Smokers consumed considerably more alcohol than did nonsmokers at both time points. However, a significant interaction of Smoking Status x Time showed that while smokers had consumed fewer units of alcohol after the ban, nonsmokers showed an increase over the same period. There was a significant reduction in number of cigarettes consumed after the ban. Subjective norms concerning not smoking, and perceived severity of smoking-related illness increased across time. Negative outcomes associated with not smoking were reduced among former smokers and increased across time among smokers. Regression analyses showed that changes in subjective norm and negative outcome expectancies accounted for significant variance in change in smoking across time. Results suggest that the smoking ban may have positive health benefits that are supported by social-cognitive change. PsycINFO Database Record (c) 2009 APA, all rights reserved.

Biochemical and Structural Analysis of an Eis Family Aminoglycoside Acetyltransferase from Bacillus anthracis

DOE Office of Scientific and Technical Information (OSTI.GOV)

Green, Keith D.; Biswas, Tapan; Chang, Changsoo

Proteins from the enhanced intracellular survival (Eis) family are versatile acetyltransferases that acetylate amines at multiple positions of several aminoglycosides (AGs). Their upregulation confers drug resistance. Homologues of Eis are present in diverse bacteria, including many pathogens. Eis from Mycobacterium tuberculosis (Eis_Mtb) has been well characterized. In this study, we explored the AG specificity and catalytic efficiency of the Eis family protein from Bacillus anthracis (Eis_Ban). Kinetic analysis of specificity and catalytic efficiency of acetylation of six AGs indicates that Eis_Ban displays significant differences from Eis_Mtb in both substrate binding and catalytic efficiency. The number of acetylated amines was alsomore » different for several AGs, indicating a distinct regiospecificity of Eis_Ban. Furthermore, most recently identified inhibitors of Eis_Mtb did not inhibit Eis_Ban, underscoring the differences between these two enzymes. To explain these differences, we determined an Eis_Ban crystal structure. The comparison of the crystal structures of Eis_Ban and Eis_Mtb demonstrates that critical residues lining their respective substrate binding pockets differ substantially, explaining their distinct specificities. Our results suggest that acetyltransferases of the Eis family evolved divergently to garner distinct specificities while conserving catalytic efficiency, possibly to counter distinct chemical challenges. The unique specificity features of these enzymes can be utilized as tools for developing AGs with novel modifications and help guide specific AG treatments to avoid Eis-mediated resistance.« less

Evaluation of implementation, compliance and acceptance of partial smoking bans among hospitality workers before and after the Swiss Tobacco Control Act.

2015-03-01

The World Health Organization recommends uniform comprehensive smoking bans in public places. In Switzerland, regulations differ between various areas and are mostly incomplete for hospitality venues. As ambiguous regulations offer more leeway for implementation, we evaluated the Swiss regulations with respect to their effects on implementation, acceptance and compliance among hospitality workers. In our longitudinal study, a standardized, self-administered questionnaire was mailed to a sample of 185 hospitality workers before and 4-6 month after the smoking ban came into effect. The matched longitudinal sample comprised 71 participants (repeated response rate 38.4%). We developed a seven-item acceptance scale. Logistic regressions were performed to explore the factors associated with acceptance. Acceptance of smoking bans was influenced by smoking status and perceived annoyance with second-hand smoke in private. Although not statistically significant (P = 0.09), we found some indications that post-ban acceptance increased in an area with strict regulations, whereas it decreased in two areas with less stringent regulations. Tobacco bans in Swiss hospitality venues are still in a period of consolidation. The incomplete nature of the law may also have had a negative impact on the development of greater acceptance. © The Author 2014.

The future of nano-food largely hinges on public perceptions and willingness to accept this novel technology. The present study utilizes the scientific literacy model and psychometric paradigm as the key theoretical frameworks to examine the factors influencing public support for labeling and banning of nano-food in Singapore. Using data collected from a nationally representative survey of 1001 respondents, the findings demonstrated that attitudes toward technology, preference for natural product, science knowledge, and risk perception were found to substantially affect public support for both labeling and banning of nano-food. Conversely, attention to food safety news on traditional media and attention to nano-news on new media were only associated with public support for labeling of nano-food. Similarly, benefit perception was only significantly associated with public support for banning of nano-food. Theoretically, these findings support the growing body of literature that argues for the significant role played by predispositions, media use, science knowledge, and risk and benefit perceptions on attitude formation toward nano-food. It serves as the pioneering piece to address the aspect of banning in the field of nano-food. Practically, insights drawn from this study could aid relevant stakeholders in enlisting effecting strategies to convey the benefits of nano-food while mitigating the risk perceptions among the public.

Lead shot from hunting adds the toxic metal to environments worldwide. The United States banned lead shot for hunting waterfowl in 1991 and 26 states have lead shot restrictions beyond those mandated for waterfowl hunting. The Minnesota Department of Natural Resources (MDNR) was interested in studying hunter attitudes about expanded restrictions on the use of lead shot for hunting small game to understand what communication strategies might increase public support for potential restrictions on lead shot. We mailed messages about lead shot, including 1,200 control messages and 400 of each of 9 treatment messages, and surveys to 4,800 resident small game hunters. We compared attitudes and intentions related to a possible ban among control and treatment groups. Compared to the control message, all treatment messages elicited more positive attitudes and intentions to support a ban. A basic factual message, messages with references to Ducks Unlimited, and a first-person narrative message generated the strongest support for a ban. Results also demonstrated a substantial relationship between the use of lead shot and response to persuasive messages supporting a ban.

Potential consequences of the immigration ban on the scientific community.

On January 27, 2017, President Trump signed an executive order banning the citizens of 7 countries from obtaining US entry visas for the next 90 days. Since the announcement, the news media have devoted a large portion of their coverage to the ban and its political ramifications. There have been arguments made by both sides that the ban will make our country safer, while others have argued that this executive order will result in the weakening of our country and bolstering of our enemies. As a physician-scientist who was born in Iran and immigrated to the US, I will stay away from the politics of this executive order; rather, I want to discuss the impact of the immigration ban on scientific discourse, education, and research programs, and how it may influence the dissemination of knowledge to physicians and scientists in low- and middle-income countries. I will use my own experience as an example of how the educational and scientific systems in this country benefit those who strive to learn in a free and intellectually stimulating environment.

A cDNA clone highly expressed in ripe banana fruit shows homology to pectate lyases.

PubMed

1997-07-01

A cDNA clone (Ban17), encoding a protein homologous to pectate lyase, has been isolated from a cDNA library from climacteric banana fruit by means of differential screening. Northern analysis showed that Ban17 mRNA is first detected in early climacteric fruit, reaches a steady-state maximum at the climacteric peak, and declines thereafter in overripe fruit. Accumulation of the Ban17 transcript can be induced in green banana fruit by exogenous application of ethylene. The demonstrates that expression of this gene is under hormonal control, its induction being regulated by the rapid increase in ethylene production at the onset of ripening. The deduced amino acid sequence derived from the Ban17 cDNA shares significant identity with pectate lyases from pollen and plant pathogenic bacteria of the genus Erwinia. Similarity to bacterial pectate lyases that were proven to break down the pectic substances of the plant cell wall suggest that Ban17 might play a role in the loss of mesocarp firmness during fruit ripening.

Impact of a smoking ban in public places: a rapid assessment in the Seychelles.

2011-11-01

We assessed the impact of a smoking ban in hospitality venues in the Seychelles 9 months after legislation was implemented. Survey officers observed compliance with the smoking ban in 38 most popular hospitality venues and administered a structured questionnaire to two customers, two workers and one manager in each venue. Virtually no customers or workers were seen smoking in the indoor premises. Patrons, workers and managers largely supported the ban. The personnel of the hospitality venues reported that most smokers had no difficulty refraining from smoking. However, a third of workers did not systematically request customers to stop smoking and half of them did not report adequate training. Workers reported improved health. No substantial change in the number of customers was noted. A ban on public smoking was generally well implemented in hospitality venues but some less than optimal findings suggest the need for adequate training of workers and strengthened enforcement measures. The simple and inexpensive methodology used in this rapid survey may be a useful approach to evaluate the implementation and impact of clean air policy in low and middle-income countries.

A novel strategy which combines iteratively cubic spline fitting baseline correction method with discriminant partial least squares qualitative analysis is employed to analyze the surface enhanced Raman scattering (SERS) spectroscopy of banned food additives, such as Sudan I dye and Rhodamine B in food, Malachite green residues in aquaculture fish. Multivariate qualitative analysis methods, using the combination of spectra preprocessing iteratively cubic spline fitting (ICSF) baseline correction with principal component analysis (PCA) and discriminant partial least squares (DPLS) classification respectively, are applied to investigate the effectiveness of SERS spectroscopy for predicting the class assignments of unknown banned food additives. PCA cannot be used to predict the class assignments of unknown samples. However, the DPLS classification can discriminate the class assignment of unknown banned additives using the information of differences in relative intensities. The results demonstrate that SERS spectroscopy combined with ICSF baseline correction method and exploratory analysis methodology DPLS classification can be potentially used for distinguishing the banned food additives in field of food safety.

Drive-away policing and situational crime prevention in China: an analysis of motorcycle ban (jinmo) policy in Guangzhou.

PubMed

Xu, Jianhua

2012-04-01

Using the example of motorcycle ban policy in Guangzhou, the capital of Guangdong province, this article examines how situational crime prevention strategies are used in contemporary urban China. The article argues that although a motorcycle ban policy may reduce motorcycle snatch theft (feiche qiangduo) in Guangzhou, it inevitably caused a problem of displacement. However, some types of displacement are desirable for local government. An argument about drive-away policing is proposed in this article to understand policing styles in contemporary China. In addition, the article argues that motorcycle ban, as a strategy to prevent snatch theft and robbery, is also a strategy to deal with the crisis in police legitimacy. Therefore, crime prevention in China has more social and political significance than just reducing crime.

Events leading up to the signing of the partial test ban treaty in 1963 are traced from the first public concern about nuclear testing in 1954 when a hydrogen bomb was detonated in the Pacific, through Albert Schweitzer's 1957 appeal for a ban on nuclear tests; agreements between the United States, the Soviet Union, and the United Kingdom to start formal negotiations; growth in medical and scientific concern in the early 1960s; to the impetus provided by the Cuban missile crisis of October 1962. Arguments for and against a comprehensive test ban treaty are discussed. Current activity by doctors and health professionals grows out of the successful campaign waged by doctors and scientists against atmospheric testing and is held to constitute a uniquely important exercise in primary prevention.

2017-02-01

This study examined whether a policy of banning tobacco product retailers from operating within 1000 feet of schools could reduce existing socioeconomic and racial/ethnic disparities in tobacco retailer density. We geocoded all tobacco retailers in Missouri (n = 4730) and New York (n = 17 672) and linked them with Census tract characteristics. We then tested the potential impact of a proximity policy that would ban retailers from selling tobacco products within 1000 feet of schools. Our results confirmed socioeconomic and racial/ethnic disparities in tobacco retailer density, with more retailers found in areas with lower income and greater proportions of African American residents. A high proportion of retailers located in these areas were in urban areas, which also have stores located in closer proximity to schools. If a ban on tobacco product sales within 1000 feet of schools were implemented in New York, the number of tobacco retailers per 1000 people would go from 1.28 to 0.36 in the lowest income quintile, and from 0.84 to 0.45 in the highest income quintile. In New York and Missouri, a ban on tobacco product sales near schools would either reduce or eliminate existing disparities in tobacco retailer density by income level and by proportion of African American. Proximity-based point of sale (POS) policies banning tobacco product sales near schools appear to be more effective in reducing retailer density in lower income and racially diverse neighborhoods than in higher income and white neighborhoods, and hold great promise for reducing tobacco-related disparities at the POS. Given the disparities-reducing potential of policies banning tobacco product sales near schools, jurisdictions with tobacco retailer licensing should consider adding this provision to their licensing requirements. Since relatively few jurisdictions currently ban tobacco sales near schools, future research should examine ways to increase and monitor the uptake of this policy, and assess whether it has an impact upon reducing exposure to tobacco marketing and on tobacco product availability and use. © The Author 2016.

Across the United States, many states have actively banned the sale of soda in high schools, and evidence suggests that students' in-school access to soda has declined as a result. However, schools may be substituting soda with other sugar-sweetened beverages (SSBs), and national trends indicate that adolescents are consuming more sports drinks and energy drinks. This study examined whether students consumed more non-soda SSBs in states that banned the sale of soda in school. Student data on consumption of various SSBs and in-school access to vending machines that sold SSBs were obtained from the National Youth Physical Activity and Nutrition Study (NYPANS), conducted in 2010. Student data were linked to state laws regarding the sale of soda in school in 2010. Students were cross-classified based on their access to vending machines and whether their state banned soda in school, creating 4 comparison groups. Zero-inflated negative binomial models were used to compare these 4 groups with respect to students’ self-reported consumption of diet soda, sports drinks, energy drinks, coffee/tea, or other SSBs. Students who had access to vending machines in a state that did not ban soda were the reference group. Models were adjusted for race/ethnicity, sex, grade, home food access, state median income, and U.S. Census region. Students consumed more servings of sports drinks, energy drinks, coffee/tea, and other SSBs if they resided in a state that banned soda in school but attended a school with vending machines that sold other SSBs. Similar results were observed where schools did not have vending machines but the state allowed soda to be sold in school. Intake was generally not elevated where both states and schools limited SSB availability – i.e., states banned soda and schools did not have SSB vending machines. State laws that ban soda but allow other SSBs may lead students to substitute other non-soda SSBs. Additional longitudinal research is needed to confirm this. Elevated SSB intake was not observed when both states and schools took steps to remove SSBs from school.

Healthy public policy is an important tool for creating environments that support human health and wellbeing. At the local level, municipal policies, such as zoning bylaws, provide an opportunity for governments to regulate building location and the type of services offered. Across North America, there has been a recent proliferation of municipal bylaws banning fast food drive-through services. Research on the utilization of this policy strategy, including bylaw adopters and adopter characteristics, is limited within the Canadian context. The aim of this study was to identify and characterize Canadian municipalities based on level of policy innovation and nature of their adopted bylaw banning fast food drive-through services. A multiple case history methodology was utilized to identify and analyse eligible municipal bylaws, and included development of a chronological timeline and map of adopter municipalities within Canada. Grey literature and policy databases were searched for potential adopters of municipal fast food drive-through service bylaws. Adopters were confirmed through evidence of current municipal bylaws. Geographic diffusion and diffusion of innovations theories provided a contextual framework for analysis of bylaw documents. Analysis included assignment of adopter-types, extent and purpose of bans, and policy learning activities of each adopter municipality. From 2002 to 2016, 27 municipalities were identified as adopters: six innovators and twenty-one early adopters. Mapping revealed parallel geographic diffusion patterns in western and eastern Canada. Twenty-two municipalities adopted a partial ban and five adopted a full ban. Rationales for the drive-through bans included health promotion, environmental concerns from idling, community character and aesthetics, traffic concerns, and walkability. Policy learning, including research and consultation with other municipalities, was performed by nine early adopters. This study detailed the adoption of fast food drive-through bylaws across Canada. Understanding the adopter-type characteristics of municipalities and the nature of their bylaws can assist other jurisdictions in similar policy efforts. While the implications for research and practice are evolving and dynamic, fast food drive-through service bans may play a role in promoting healthier food environments. Further research is required to determine the viability of this strategy for health promotion and chronic disease prevention.

Rayleigh-wave diffractions due to a void in the layered half space

2006-01-01

Void detection is challenging due to the complexity of near-surface materials and the limited resolution of geophysical methods. Although multichannel, high-frequency, surface-wave techniques can provide reliable shear (S)-wave velocities in different geological settings, they are not suitable for detecting voids directly based on anomalies of the S-wave velocity because of limitations on the resolution of S-wave velocity profiles inverted from surface-wave phase velocities. Xia et al. (2006a) derived a Rayleigh-wave diffraction traveltime equation due to a void in the homogeneous half space. Encouraging results of directly detecting a void from Rayleigh-wave diffractions were presented (Xia et al., 2006a). In this paper we used four two-dimensional square voids in the layered half space to demonstrate the feasibility of detecting a void with Rayleigh-wave diffractions. Rayleigh-wave diffractions were recognizable for all these models after removing direct surface waves by F-K filtering. We evaluate the feasibility of applying the Rayleigh-wave diffraction traveltime equation to a void in the layered earth model. The phase velocity of diffracted Rayleigh waves is predominately determined by surrounding materials of a void. The modeling results demonstrate that the Rayleigh-wave diffraction traveltime equation due to a void in the homogeneous half space can be applied to the case of a void in the layered half space. In practice, only two diffraction times are necessary to define the depth to the top of a void and the average velocity of diffracted Rayleigh waves. ?? 2005 Society of Exploration Geophysicists.

How does electronic cigarette access affect adolescent smoking?

PubMed

Friedman, Abigail S

2015-12-01

Understanding electronic cigarettes' effect on tobacco smoking is a central economic and policy issue. This paper examines the causal impact of e-cigarette access on conventional cigarette use by adolescents. Regression analyses consider how state bans on e-cigarette sales to minors influence smoking rates among 12 to 17 year olds. Such bans yield a statistically significant 0.9 percentage point increase in recent smoking in this age group, relative to states without such bans. Results are robust to multiple specifications as well as several falsification and placebo checks. This effect is both consistent with e-cigarette access reducing smoking among minors, and large: banning electronic cigarette sales to minors counteracts 70 percent of the downward pre-trend in teen cigarette smoking for a given two-year period.

During the last 25 years, scientific experimental and clinical studies have documented the dangers of cornstarch powder on examination and surgical gloves because the cornstarch promotes wound infection, causes serious peritoneal adhesions and granulomatous peritonitis, and is a well-documented vector of the latex allergy epidemic in the world. Realizing the dangers of cornstarch on examination and surgical gloves, Germany's regulations of personal protective equipment banned the use of surgical glove powder cornstarch in 1997. In 2000, the Purchasing and Supply agency for the United Kingdom ceased to purchase any gloves lubricated with cornstarch. Realizing the dangers of cornstarch-powdered gloves, many hospitals and clinics in the United States have banned the use of cornstarch-powdered examination and surgical gloves. Hospitals that have banned cornstarch in their examination and surgical gloves have noted a marked reduction in the latex allergy epidemic in their facilities. Realizing the dangers of cornstarch-powdered examination and surgical gloves, Dr Sheila A. Murphey, branch chief, Infection Control Devices Branch, Division of Anesthesiology, General Hospital, Infection Control, and Dental Devices Office of Device Evaluation, Center for Devices and Radiological Health of the Food and Drug Administration (FDA), recommended that a Citizen's Petition be filed to the FDA to ban cornstarch on surgical and examination gloves. The 12 authors of this report have attached the enclosed petition to the FDA to ban the use of cornstarch on all synthetic and latex examination and surgical gloves used in the United States.

Abstract Objective To evaluate the effect of a smoking ban in high schools on smoking behaviour among Chilean students. Methods We conducted an interrupted time-series analysis, using repeated cross-sectional data from Chile’s school population survey (2000–2011) for high-school students aged 12–18 years and a control group of persons aged 19–24 years. Poisson regression models were used to assess trends in smoking behaviour before and after the policy changes. The outcome measures were self-reported smoking prevalence (any smoking in the past month) and high frequency of smoking (smoking 15 days or more per month). Findings From 2005 to 2011, the prevalence of smoking declined among high-school students by 6.8% per year compared with 3.6% decline per year in the control group. The decline in the target group was 2.9% (95% confidence interval, CI: 0.18 to 5.00) greater. We estimated that 5–6 years after enforcing the law, smoking prevalence among high-school students was 13.7% lower as a result of the ban. The impact of the smoking ban was primarily driven by declines in smoking prevalence among students in grades 8 to 10. The smoking ban did not significantly alter the frequency of smoking. Conclusion The 2005 school smoking ban reduced smoking prevalence among younger high-school students in Chile. Further interventions targeting older individuals and frequent smokers may be needed.

The partial-birth stratagem.

PubMed

1998-06-01

In Wisconsin, physicians stopped performing abortions when a Federal District Court Judge refused to issue a temporary restraining order against the state's newly enacted "partial birth" abortion ban that was couched in such vague language it actually covered all abortions. While ostensibly attempting to ban late-term "intact dilation and extraction," the language of the law did not refer to that procedure or to late terms. Instead, it prohibited all abortions in which a physician "partially vaginally delivers a living child, causes the death of the partially delivered child with the intent to kill the child and then completes the delivery of the child." The law also defined "child" as "a human being from the time of fertilization" until birth. It is clear that this abortion ban is unconstitutional under Row v. Wade, and this unconstitutionality is compounded by the fact that the law allowed no exception to protect a woman's health, which is required by Roe for abortion bans after fetal viability. Wisconsin is only one of about 28 states that have enacted similar laws, and only two have restricted the ban to postviability abortions. Many of these laws have been struck down in court, and President Clinton has continued to veto the Federal partial-birth bill. The Wisconsin Judge acknowledged that opponents of the ban will likely prevail when the case is heard, but his action in denying the temporary injunction means that many women in Wisconsin will not receive timely medical care. The partial birth strategy is really only another anti-abortion strategy.

Gifts and influence: Conflict of interest policies and prescribing of psychotropic medications in the United States.

The pharmaceutical industry spends roughly 15 billion dollars annually on detailing - providing gifts, information, samples, trips, honoraria and other inducements - to physicians in order to encourage them to prescribe their drugs. In response, several states in the United States adopted policies that restrict detailing. Some states banned gifts from pharmaceutical companies to doctors, other states simply required physicians to disclose the gifts they receive, while most states allowed unrestricted detailing. We exploit this geographic variation to examine the relationship between gift regulation and the diffusion of four newly marketed medications. Using a dataset that captures 189 million psychotropic prescriptions written between 2005 and 2009, we find that uptake of new costly medications was significantly lower in states with marketing regulation than in areas that allowed unrestricted pharmaceutical marketing. In states with gift bans, we observed reductions in market shares ranging from 39% to 83%. Policies banning or restricting gifts were associated with the largest reductions in uptake. Disclosure policies were associated with a significantly smaller reduction in prescribing than gift bans and gift restrictions. In states that ban gift-giving, peer influence substituted for pharmaceutical detailing when a relatively beneficial drug came to market and provided a less biased channel for physicians to learn about new medications. Our work suggests that policies banning or limiting gifts from pharmaceutical representatives to doctors are likely to be more effective than disclosure policies alone. Copyright © 2016 Elsevier Ltd.

Sunbed use in childhood increases risk of melanoma. The under-18s sunbed ban was introduced in England, April 2011. Impact on use has not been investigated since. This cross-sectional study estimates the prevalence of under-18s' use in Sandwell after the commercial ban and identifies factors associated with use/intention. Adolescents aged 15 to 17 years in schools were surveyed using self-completed anonymous questionnaires. Data collected include demographics, sunbed use, tanning attitudes, knowledge of risks and ban awareness. All Sandwell schools were approached; adolescents available on the survey days were included. Five out of 22 schools participated, 407 adolescents responded (95.1%). Twenty participants (5.3%; 95% confidence interval [CI] = 3.4-8.0) had used sunbeds, of who 16 reported use in commercial settings. After exclusion of one school cohort with atypical use (possibly associated with beauty vocational course and European migrants), the prevalence of use was 1.7% (95% CI = 0.7-3.9, n = 5). Less than half of all were aware of the ban (48.2%; 95% CI = 43.2-53.3). Users/potential users were less aware of associated risks. Being female, having family/friends who use sunbeds increased use/intention 2- to 4-fold. Strategies targeting parents, stricter enforcement, and greater publicity of the ban are needed. Further research exploring the possible association between certain vocational courses, migrants, and sunbed use is required.

Families at Risk: Home and Car Smoking Among Pregnant Women Attending a Low-Income, Urban Prenatal Clinic

Introduction: Secondhand smoke exposure (SHSe) has been identified as a distinct risk factor for adverse obstetric and gynecological outcomes. This study examined the prevalence of SHSe reduction practices (i.e., home and car smoking bans) among pregnant women in a large U.S. prenatal clinic serving low-income women. Methods: Pregnant women (N = 820) attending a university-based, urban prenatal clinic in Houston, Texas, completed a prenatal questionnaire assessing bans on household and car smoking and a qualitative urine cotinine test as part of usual care. Data were collected from April 2011 to August 2012. Results: Nearly one-third (n = 257) of the sample reported at least 1 smoker living in the home. About a quarter of the women in the full sample did not have a total smoking ban in their home and car. Within smoking households, 44% of the pregnant women reported smoking, 56% reported smoking by another household member, and in 26% of smoking households both the pregnant woman and at least one other person were smoking. Only 43% of women with a household smoker reported a total ban on smoking, with higher rates among Hispanic women. Smoking bans were less common when the pregnant women smoked, when more than 1 smoker resided in the home, and when pregnant with her first child. Conclusions: SHSe among low-income pregnant women is high, and interventions to raise awareness and increase the establishment of smoking bans in homes and cars are warranted. PMID:24692668

To determine compliance with a voluntary code of practice (VCP) for restricting smoking in restaurants and to canvass the attitudes of restaurateurs towards tougher smoking restrictions. Cross-sectional survey conducted in 1996 using a telephone questionnaire. Metropolitan restaurants and cafes in Adelaide, South Australia. 276 (86.8%) of a sample of randomly selected owners and managers. Restaurant non-smoking policies, reported and anticipated change in business, and restaurateurs' attitudes towards smoking restrictions. 26.8% of restaurants had a total smoking ban; 40.6% restricted smoking some other way; and 32.6% permitted unrestricted smoking. Only 15.1% of restaurants with a ban or restrictions had used the VCP to guide the development of their policy, and only half of these were complying with it. Although 78.4% of those with bans and 84.4% of those with restrictions reported that their non-smoking policy had been associated with either no change or a gain in business, only 33.3% of those allowing unrestricted smoking expected that this would be the case, if they were to limit smoking. A total of 50.4% of restaurateurs, including 45.3% of those with no restrictions, agreed that the government should ban smoking in all restaurants. The VCP made an insignificant contribution to adoption of non-smoking policies, and compliance with the code was poor. Despite concerns about loss of business, there was considerable support for legislation which would ban smoking in all dining establishments.

Drug policing assemblages: Repressive drug policies and the zonal banning of drug users in Denmark's club land.

2017-03-01

Zonal banning of disorderly and intoxicated young people has moved to centre stage in debates about nightlife governance. Whereas existing research has primarily focused on the use of zonal banning orders to address problems of alcohol-related harm and disorder, this article highlights how zonal banning is also used to target drug-using clubbers in Denmark. Based on ethnographic observations and interviews with nightlife control agents in two Danish cities, the article aims to provide new insights into how the enforcement of national drug policies on drug-using clubbers, is shaped by plural nightlife policing complexes. The paper demonstrates how the policing of drug-using clubbers is a growing priority for both police and private security agents. The article also demonstrates how the enforcement of zonal bans on drug-using clubbers involves complex collaborative relations between police, venue owners and private security agents. The paper argues that a third-party policing perspective combined with assemblage theory is useful for highlighting how the enforcement of national drug policies and nightlife banning systems is shaped by their embeddedness in local 'drug policing assemblages' characterized by inter-agency relation-building, the creative combination of public and private (legal) resources and internal power struggles. It also provides evidence of how drug policing assemblages give rise to many different, and often surprising, forms of jurisdiction involving divergent performances of spaces-, objects- and authorities of governance.

The banning of sales of nicotine e-liquid in e-cigarette shops has been implemented in several states in Malaysia. The distribution of nicotine e-liquid can only be allowed by licensed pharmacies or registered medical practitioners. This study aimed to evaluate e-cigarette users' responses to the control policy in a cross-sectional survey of 851 e-cigarette users by utilizing a self-report questionnaire that assessed (1) attitudes on regulation policy of e-cigarette banning; (2) e-cigarette use behaviors; and (3) sources of e-liquid after the regulation policy has been implemented. Participants from the state of Selangor where the banning policy was implemented were surveyed. The majority (95.8%) opposed the banning and believed e-cigarettes should be sold to anyone aged 18 years or above as with tobacco cigarettes, only a minority believed that nicotine e-liquid should only be available for sale over the counter in pharmacy stores (14.6%) and in clinics with a doctor's prescription (11.8%). The majority (44.2%) reported that they would continue their e-cigarette use as before the banning policy, while 20% plan to completely stop e-cigarette usage without replacing it with any alternatives. The vast majority (87.9%) was still able to obtained nicotine e-liquid from e-cigarette shops in spite of the ban and the second most common source was from online purchase (63.1%). The sales of nicotine e-liquid from black-market were evidenced as many reported obtaining zero nicotine e-liquid from the black market (54.4%). Self- or home-made (30.8%) nicotine e-liquid was also reported. Majority of respondents that self-made e-liquid were from the average monthly income group (below MYR3000). Obtaining nicotine from the pharmacy was least preferred (21.4%). Provision of professional advice to nicotine e-liquid users along with the ban may lessen the likelihood of users switching to tobacco cigarettes or other nicotine alternatives. Banning of sales of nicotine e-liquid in e-cigarette shops resulted in a boom in the black market supplying nicotine e-liquid and, self- or home-made nicotine e-liquid. Enforcing regulations and monitoring black market sales is warranted. Efforts to educate e-cigarette users of the danger of sourcing nicotine e-liquid from the black market and self- or home-made nicotine e-liquid are essential.

Holocene Geologic Slip Rate for the Banning Strand of the Southern San Andreas Fault near San Gorgonio Pass, Southern California

We present the first Holocene geologic slip rate for the Banning strand of the southern San Andreas Fault in southern California. The southern San Andreas Fault splays into the sub-parallel Banning and Mission Creek strands in the northwestern Coachella Valley, and although it has long been surmised that the Banning strand eventually accommodates the majority of displacement and transfers it into San Gorgonio Pass, until now it has been uncertain how slip is actually partitioned between these two fault strands. Our new slip rate measurement, critically located at the northwestern end of the Banning strand, overlaps within errors with the published rate for the southern San Andreas Fault measured at Biskra Palms Oasis. This indicates that the majority of southern San Andreas Fault displacement transfers from the southeastern Mission Creek strand northwest to the Banning strand and into San Gorgonio Pass. Our result corroborates the UCERF3 hazard model, and is consistent with most previous interpretations of how slip is partitioned between the Banning and Mission Creek fault strands. To measure this slip rate, we used B4 airborne LiDAR to identify the apex of an alluvial fan offset laterally 30 ± 5 m from its source. We calculated the depositional age of the fan using 10Be in-situ cosmogenic exposure dating of 5 cobbles and a depth profile. We calculated a most probable fan age of 4.0 +2.0/-1.6 ka (1σ) by combining the inheritance-corrected cobble ages assuming Gaussian uncertainty. However, the probability density function yielded a multi-peaked distribution, which we attribute to variable 10Be inheritance in the cobbles, so we favor the depth profile age of 2.2-3.6 ka. Combined, these measurements yield a late Holocene slip rate for the Banning strand of the southern San Andreas Fault of 11.1 +3.1/-3.3 mm/yr. This slip rate does not preclude possibility that some slip transfers north along the Mission Creek strand and the Garnet Hill fault, but it does confirm that the Banning strand has been the most probable rupture path for earthquakes nucleated on the southern San Andreas Fault over the past few thousand years, and is likely to remain so in the near future. This clarification of slip partitioning within the northwest Coachella Valley is timely given that the southern San Andreas Fault is considered overdue for a large earthquake.

One-third of Mexican-American children, in addition to nonsmoker adults, are exposed to secondhand smoke at home, yet few interventions target Mexican-American households. An effective, brief English language program, tested with United Way 2-1-1 callers in Atlanta, increased home smoking bans (confirmed by air monitors). Two randomized controlled trials in North Carolina and Texas replicated those results. We explored factors determining adoption and enforcement of smoking bans in Mexican-American households to inform program linguistic and cultural adaptation to broaden program reach and relevance. Bilingual interviewers recruited convenience samples of Mexican-American smokers and nonsmokers living with at least one smoker in Houston and San Diego households and asked open-ended questions regarding conditions for implementing home and vehicle smoking bans and conditions for varying acceptance of bans. Investigators independently reviewed English transcripts and completed a descriptive analysis using ATLAS.ti. Participants (n = 43) were predominantly female (n = 31), current smokers (n = 26), interviewed in Spanish (n = 26), had annual household incomes less than $30000 (n = 24), and allowed smoking inside the home (n = 24). Themes related to difficulty creating and enforcing bans included courtesy, respect for guests and heads of household who smoke, and gender imbalances in decision making. Participants viewed protecting children's health as a reason for the ban but not protecting adult nonsmokers' health. A dual-language, culturally adapted intervention targeting multigenerational Mexican-American households should address household differences regarding language and consider influences of cultural values on family dynamics and interactions with guests that may weaken bans. Qualitative interviews suggested cultural and family considerations to address in adapting a brief evidence-based smoke-free homes intervention for Mexican Americans, including traditional gender roles, unique contexts of multigenerational households, and language preferences. Our work confirms previous research among Latinos regarding importance of common cultural constructs, such as respeto (deference), simpatia (courtesy and agreeability), and familismo (family attachment), which inform behaviors that may impede or facilitate adopting and enforcing home smoking bans. Decision-making gender imbalances, high regard for head-of-household and guest smokers, and less sensitivity to the health of nonsmoker adults compared with children may lead to permission to smoke indoors. © The Author 2017.

Transnational Dynamics Amid Poor Regulations: Taiwan's Asbestos Ban Actions and Experiences.

This article describes the history of the asbestos use regulation process in Taiwan and the associated factors leading to its total ban in 2018. Despite the long history of asbestos mining and manufacturing since the Japanese colonial period, attempts to understand the impact of asbestos on the health of the population and to control its use did not emerge until the early 1980s. We attempted to investigate the driving forces and obstructions involved in asbestos regulations by reviewing available public sources and scientific journal articles and conducting interviews with key propagators of the asbestos regulation and ban. Correlation between asbestos exposure and asbestos-related diseases has already been established; however, authorities have been unable to effectively regulate the extensive application of asbestos in various light industries that support economic growth since the 1960s. More stringent regulations on asbestos use in industries and an eventual ban were caused indirectly by appeals made by visionary scholars and healthcare professionals but also due to the subsidence of asbestos-related industries. With the elucidation of factors that affect asbestos regulation and ban, a thorough long-term healthcare plan for the neglected victims of asbestos-related diseases and upstream measures for policy change must be developed.

Fourteen US states and the District of Columbia have banned handheld phone use for all drivers. We examined whether such legislation was associated with reduced handheld phone conversations among drivers aged younger than 25 years. Data from the 2008 to 2013 National Occupant Protection Use Survey were merged with states' legislation. The outcome was roadside-observed handheld phone conversation at stop signs or lights. Logistic regression was used. A total of 32,784 young drivers were observed. Relative to drivers who were observed in states without a universal handheld phone ban, the adjusted odds ratio of phone conversation was 0.42 (95% confidence interval, 0.33-0.53) for drivers who were observed in states with bans. The relative reduction in phone conversation was 46% (23%, 61%) for laws that were effective less than 1 year, 55% (32%, 70%) for 1-2 years, 63% (51%, 72%) for 2 years or more, relative to no laws. Universal handheld phone bans may be effective at reducing handheld phone use among young drivers. Copyright © 2016 Elsevier Inc. All rights reserved.

In response to the dramatic increase in alcohol-related problems in Lithuania, policy measures, including alcohol advertising and availability restrictions combined with taxation increase, were implemented in 2007-08. Simultaneously, a full alcohol advertising ban was adopted to take effect from 1 January 2012. Therefore, the alcohol industry responded with extensive lobbying aiming to revoke this ban, and ultimately they succeeded at the end of December 2011. To document and analyse actions of stakeholders and events during the alcohol advertising ban cancellation process in Lithuania. Policy analysis includes a development of event time-line, description of key stakeholders' actions and a review of policy context. The alcohol industry in Lithuania used similar tactics as the tobacco industry globally, such as creating strong and diverse opposing groups. The industry successfully exerted pressure to change alcohol control legislation, while non-governmental organizations had the important role of a watchdog, blunting industry's efforts. Unequal power distribution made it difficult to withstand combined local and international lobbying to cancel the ban. Given the global nature of the alcohol industry, there is a need for international regulation to limit the influence of vested interests on national lawmaking. © 2014 Society for the Study of Addiction.

Health and doping in elite-level cycling.

The protection of the health of athletes is one of the three criteria taken into account when registering a substance in the World Anti-Doping Agency prohibited list. Nevertheless, in elite-level cycling, banned substance use is widespread. The present research adopted a psychological approach to examine how or whether perceived health risks influence elite-level cyclists' decisions to use banned substances. Sixteen semi-structured interviews were conducted with cyclists hoping to join a professional team (n=6), neo-professional cyclists (n=2), and former professional cyclists (n=8). Although an evolution was observed in the organization of doping and perceptions of doping over the last decade, the perceived health hazards did not influence, most of the time, decisions to use banned substances among the sample of cyclists. There was a systematization of exogenous substance use in the cycling environment and a trivialization of the side effects of the banned substances. Finally, younger cyclists were not concerned about the long-term health consequences of banned substances; they were more focused on the short-term performance-enhancing benefits. There is a need to implement more effective preventive programs to change athletes' attitudes toward doping and its health risks. © 2011 John Wiley & Sons A/S.

FDA's proposed ban on trans fats: How do the costs and benefits stack up?

PubMed

Cohen, Joshua T

2014-03-01

The goal of this commentary was to compare the benefits and costs of the US Food and Drug Administration's proposed ban on artificial trans fats in US food versus other public health risks and interventions. This analysis assessed the remaining risk posed by artificial trans fats versus other risks, comparing them in terms of: (1) population disease burden (prevention of lost life-years and decreased quality of life, aggregated and expressed as quality-adjusted life-years [QALYs]); (2) individual mortality risks for other "voluntary" activities; and (3) cost-effectiveness, which is the unit cost incurred by an intervention per QALY gained. The population impact of remaining trans fats is small compared with many other risks. Conversely, lifetime individual risks are comparable to other individual risks that might be considered notable. Finally, the ban achieves public health gains at low to no cost. The US Food and Drug Administration's ban on trans fats is sensible from the perspective of economic efficiency. Comparing the health risk addressed and the efficiency of the ban with other benchmarks can help decision makers and the population to better evaluate it. Copyright © 2014 Elsevier HS Journals, Inc.

Smoking prevalence in Germany remains high at approximately 28%. We assessed public support for tobacco legislation and associations between level of support and smoking and socio-demographic characteristics. Data from 2087 people were collected as part of the German Study on Tobacco Use (“DEBRA”): a nationally representative, face-to-face household survey. Public support was measured on total ban of sale, raising the minimum age for sales, taxation of tobacco industry sales, research into e-cigarettes, and ban of smoking in cars when children are present. Associations were assessed with multivariate logistic regression. Over 50% of the German population support taxing industry profits (57.3%) and assessing e-cigarettes as an aid to quit smoking (55.5%). Over 40% support raising the legal age of sale (43.1%), and 22.9% support a total ban on tobacco sales. A smoking ban in cars when children are present was most popular (71.5%), even among current smokers (67.0%). There is public support for stricter tobacco control measures in Germany. A smoking ban in cars when children are present could be a feasible policy to implement. PMID:29642461

Forest protection policies potentially reduce deforestation and re-direct agricultural expansion to already-cleared areas. Using satellite imagery, we assessed whether deforestation for conversion to pasture and cropland decreased in the lowlands of northern Costa Rica following the 1996 ban on forest clearing, despite a tripling of area under pineapple cultivation in the last decade. We observed that following the ban, mature forest loss decreased from 2.2% to 1.2% per year, and the proportion of pineapple and other export-oriented cropland derived from mature forest declined from 16.4% to 1.9%. The post-ban expansion of pineapples and other crops largely replaced pasture, exotic and native tree plantations, and secondary forests. Overall, there was a small net gain in forest cover due to a shifting mosaic of regrowth and clearing in pastures, but cropland expansion decreased reforestation rates. We conclude that forest protection efforts in northern Costa Rica have likely slowed mature forest loss and succeeded in re-directing expansion of cropland to areas outside mature forest. Our results suggest that deforestation bans may protect mature forests better than older forest regrowth and may restrict clearing for large-scale crops more effectively than clearing for pasture.

Applying a contingency model of strategic decision making to the implementation of smoking bans: a case study.

Willemsen, M C; Meijer, A; Jannink, M

1999-08-01

A model of strategic decision making was applied to study the implementation of worksite smoking policy. This model assumes there is no best way of implementing smoking policies, but that 'the best way' depends on how decision making fits specific content and context factors. A case study at Wehkamp, a mail-order company, is presented to illustrate the usefulness of this model to understand how organizations implement smoking policies. Interview data were collected from representatives of Wehkamp, and pre- and post-ban survey data were collected from employees. After having failed to solve the smoking problem in a more democratic way, Wehkamp's top management choose a highly confrontational and decentralized decision-making approach to implement a complete smoking ban. This resulted in an effective smoking ban, but was to some extent at the cost of employees' satisfaction with the policy and with how the policy was implemented. The choice of implementation approach was contingent upon specific content and context factors, such as managers' perception of the problem, leadership style and legislation. More case studies from different types of companies are needed to better understand how organizational factors affect decision making about smoking bans and other health promotion innovations.

R2NA: Received Signal Strength (RSS) Ratio-Based Node Authentication for Body Area Network

2013-01-01

The body area network (BAN) is an emerging branch of wireless sensor networks for personalized applications. The services in BAN usually have a high requirement on security, especially for the medical diagnosis. One of the fundamental directions to ensure security in BAN is how to provide node authentication. Traditional research using cryptography relies on prior secrets shared among nodes, which leads to high resource cost. In addition, most existing non-cryptographic solutions exploit out-of-band (OOB) channels, but they need the help of additional hardware support or significant modifications to the system software. To avoid the above problems, this paper presents a proximity-based node authentication scheme, which only uses wireless modules equipped on sensors. With only one sensor and one control unit (CU) in BAN, we could detect a unique physical layer characteristic, namely, the difference between the received signal strength (RSS) measured on different devices in BAN. Through the above-mentioned particular difference, we can tell whether the sender is close enough to be legitimate. We validate our scheme through both theoretical analysis and experiments, which are conducted on the real Shimmer nodes. The results demonstrate that our proposed scheme has a good security performance.

The BANNING MOS design system is presented. It complements rather than supplant the normal design activities associated with the design and fabrication of low-power digital electronic equipment. BANNING is user-oriented and requires no programming experience to use effectively. It provides the user a simulation capability to aid in his circuit design and it eliminates most of the manual operations involved in the layout and artwork generation of integrated circuits. An example of its operation is given and some additional background reading is provided.

Although many countries still face opposition to the legislation of artificial tanning beds, all Australian states and territories have announced a total ban on commercial tanning beds. A combination of epidemiological and policy-centered research, powerful personal stories, and the active advocacy of prominent academics, cancer organizations, and grassroots community campaigners contributed to the decisions to first legislate standards and then ban all commercial tanning beds. We have illustrated that incremental change can be an effective pathway to securing substantial public health reforms.

Benten v. Kessler: the RU 486 import case.

PubMed

Pine, R N

1992-01-01

On July 1, 1992, the case of Benten v. Kessler was filed in the US District Court in New York. The case arose out of an attempt by abortion rights activist Lawrence Lader to call public attention to the US Food and Drug Administration's (FDA) ban on importation of the abortifacient drug mifepristone known as RU-486. The ban expresses the anti abortion stance of the Reagan and Bush administrations and creates a hostile climate for the development of new drugs related to reproductive health and reproductive choice. Plaintiffs in the Benten case sought public accountability by the FDA for its adoption of a ban of a safe and effective drug for unwanted pregnancy. Although the case did not succeed in retrieving the confiscated RU-486 pills for Leona Benten, in its opinion issued on July 14, 1992, the New York district court judge concluded that the import ban did not appear to be based on concern with the safety or effectiveness of RU-486, describing the FDA's process of adopting the import ban as a sink of illegality. On July 17, 1992, 7 Justices of the Supreme Court, with justices Blackmun and Stevens dissenting, joined in a per curiam opinion denying the application and foreclosing further personal relief for Leona Benten. This was the best result possible short of an all out victory for Leona Benten. The Court ruled against plaintiffs in their argument that notice and comment were required, but left entirely open plaintiffs' claims that the import ban is arbitrary and capricious under the Administrative Procedure Act and that the ban is unconstitutional in that it unduly burdens the right to terminate pregnancy. This backdrop creates a healthy skepticism about the prospects for the introduction of RU-486 into the US in the near future as well as about the fairness of government processes in areas of concern to women. Public health considerations, not politics, should determine access to health care.

Female genital mutilation and cosmetic surgery: regulating non-therapeutic body modification.

PubMed

Sheldon, Sally; Wilkinson, Stephen

1998-10-01

In the UK, female genital mutilation is unlawful, not only when performed on minors, but also when performed on adult women. The aim of our paper is to examine several arguments which have been advanced in support of this ban and to assess whether they are sufficient to justify banning female genital mutilation for competent, consenting women. We proceed by comparing female genital mutilation, which is banned, with cosmetic surgery, towards which the law has taken a very permissive stance. We then examine the main arguments for the prohibition of the former, assessing in each case both (a) whether the argument succeeds in justifying the ban and, if so, (b) whether a parallel argument would not also support a ban on the latter. We focus on the following arguments. Female genital mutilation should be unlawful because: (1) no woman could validly consent to it; (2) it is an oppressive and sexist practice; (3) it involves the intentional infliction of injury; (4) it causes offence. Our view is that arguments (3) and (4) are unsound and that, although arguments (1) and (2) may be sound, they support not only a ban on female genital mutilation, but also one on (some types of) cosmetic surgery. Hence, we conclude that the present legal situation in the UK is ethically unsustainable in one of the following ways. Either the ban on female genital mutilation is unjustified because arguments (1) and (2) are not in fact successful; or the law's permissive attitude towards cosmetic surgery is unjustified because arguments (1) and (2) are in fact successful and apply equally to female genital mutilation and (certain forms of) cosmetic surgery. The people of the countries where female genital mutilation is practised resent references to 'barbaric practices imposed on women by male-dominated primitive societies', especially when they look at the Western world and see women undergoing their own feminization rites intended to increase sexual desirability: medically dangerous forms of cosmetic plastic surgery, for instance....
