Project description:INTRODUCTION:To systematically review the evidence regarding the effect of standardized packaging on illicit tobacco use. METHODS:Data sources were EMBASE, Web of Knowledge, Scopus, PsycInfo, Medline, and the British Library catalogue, from 01/01/1987 to 28/11/2016. Reference lists of included studies were hand searched for additional papers. Search strategies were based on the terms 'tobacco', 'packaging' and 'illicit'. The search was restricted to English language references. Two reviewers screened titles and abstracts for empirical studies that addressed the topic of standardized packaging and illicit tobacco use. This resulted in 153 full text papers retrieved for screening. Following exclusions, ten papers were included in the review. Two reviewers' extracted data using piloted standardized data extraction forms. Studies were assessed for quality and relevance using CASP. RESULTS:There was little homogeneity between included studies, so a narrative synthesis was employed. Of the relevant studies five reported smokers did not intend to or actually purchase further illicit tobacco following standardized packaging, although one suggested a small number of responders to online news felt smokers would be more inclined to purchase illicit tobacco, following standardized packaging. Two studies reported retailers did not intend to or actually increase sales of illicit tobacco following standardized packaging. Finally, two studies reported industry data on illicit tobacco were of poor quality and not supported by independent data. CONCLUSIONS:There were few studies examining tobacco standardized packaging and illicit trade, however those available showed no evidence that standardized packaging could lead to increases in illicit trade.
Project description:OBJECTIVE:We aimed to investigate the effects of special packaging (child-resistant, adult-friendly) and tamper-resistant packaging on health and behavioral outcomes in order to identify research gaps and implications for packaging standards for tobacco products. METHODS:We searched seven databases for keywords related to special and tamper-resistant packaging, consulted experts, and reviewed citations of potentially relevant studies. 733 unique papers were identified. Two coders independently screened each title and abstract for eligibility. They then reviewed the full text of the remaining papers for a second round of eligibility screening. Included studies investigated a causal relationship between type of packaging or packaging regulation and behavioral or health outcomes and had a study population composed of consumers. Studies were excluded on the basis of publication type, if they were not peer-reviewed, and if they had low external validity. Two reviewers independently coded each paper for study and methodological characteristics and limitations. Discrepancies were discussed and resolved. RESULTS:The review included eight studies: four assessing people's ability to access the contents of different packaging types and four evaluating the impact of packaging requirements on health-related outcomes. Child-resistant packaging was generally more difficult to open than non-child-resistant packaging. Child-resistant packaging requirements have been associated with reductions in child mortality. CONCLUSIONS:Child-resistant packaging holds the expectation to reduce tobacco product poisonings among children under six.
Project description:We developed and validated a small-footprint array of miniature chemostats built from readily available parts for low cost. Physiological and experimental evolution results were similar to larger volume chemostats. The ministat array provides a compact, inexpensive, and accessible platform for traditional chemostat experiments, functional genomics, and chemical screening applications.

Physiological and experimental evolution results were similar to larger volume chemostats. The ministat array provides a compact, inexpensive, and accessible platform for traditional chemostat experiments, functional genomics, and chemical screening applications. Three experiments are gene expression comparisons between three ministat cultures and a single Sixfors sample. The four CGH arrays are individual clones evolved in four sulfate limitation ministats compared to a wt ancestor strain.
Project description:BackgroundA policy for new pictorial health warning labels on tobacco packaging was introduced by Health Canada in 2012. The labels included, for the first time, a prominently displayed toll-free number for a quit-smoking line. We used data from the Ontario provincial quitline to investigate the call volume and number of new callers receiving treatment in the months before and after the new policy was introduced.MethodsWe used an interrupted time-series analysis to examine trends in the overall call volume and number of new callers receiving treatment (≥ 1 telephone counselling session) through Ontario's quitline (Smokers' Helpline) between January 2010 and December 2013. We analyzed data using Box-Jenkins autoregressive integrated moving-average models; we adjusted the models for a major campaign promoting the quitline, a seasonality (January) effect and tobacco pricing.ResultsWe found a relative increase of 160% in the average monthly call volume during the 7 months after the introduction of the new labels (870 calls per month at baseline and 1391 additional calls per month on average after the policy change; standard error [SE] 108.94, p < 0.001), and a sustained increase of 43% in subsequent months. We observed a relative increase of 174% in the number of new callers receiving treatment (153 new callers per month at baseline and 267 additional new callers per month after the policy change; SE 40.03, p < 0.001) and a sustained increase of 80% in subsequent months. The effect was significant even after controlling for a major promotion campaign and the January effect.InterpretationWe found a significant increase in the monthly overall call volume and number of new callers receiving treatment per month after the introduction of the new tobacco health warning labels, with a sustained increase in overall calls and new callers beyond the first 7 months. Our findings add to the body of evidence on the benefit of including a toll-free quitline number on tobacco packaging.
Project description:AimsTo describe the process of enacting tobacco standardised packaging (SP) amidst tobacco industry legal threats in New Zealand.MethodsRelevant government and NGO documents, and media items were reviewed. Policymakers and health advocates in New Zealand were interviewed. The data were triangulated and thematically analysed.ResultsIn 2011, the New Zealand Government announced the goal of becoming a smokefree country (reducing smoking prevalence to 5%) by the year 2025, and considered adopting SP. In April 2012, the Government announced it would introduce SP, but tobacco companies threatened the Government with litigation in international courts for violating investment and intellectual property rights. In response, the Government adopted a 'wait and see' approach, waiting until two legal challenges against Australia's SP law were resolved before it enacted its legislation in September 2016. Health advocates, limited due to funding constraints, attempted to alter the Government's approach to the legal threats without success. Interviews with policymakers and health advocates confirmed these threats helped produce a regulatory chill, delaying the policymaking process by three years.ConclusionThe New Zealand case illustrates how the threat of a potential international lawsuit can create a chilling effect by helping delay the implementation of public health policies.
Project description:BackgroundTobacco companies use colour on cigarette packaging and labelling to communicate brand imagery, diminish health concerns, and as a replacement for prohibited descriptive words ('light' and 'mild') to make misleading claims about reduced risks.MethodsWe analysed previously secret tobacco industry documents to identify additional ways in which cigarette companies tested and manipulated pack colours to affect consumers' perceptions of the cigarettes' flavour and strength.ResultsCigarette companies' approach to package design is based on 'sensation transference' in which consumers transfer sensations they derive from the packaging to the product itself. Companies manipulate consumers' perceptions of the taste and strength of cigarettes by changing the colour of the packaging. For example, even without changes to the tobacco blends, flavourings or additives, consumers perceive the taste of cigarettes in packages with red and darker colours to be fuller flavoured and stronger, and cigarettes in packs with more white and lighter colours are perceived to taste lighter and be less harmful.ConclusionsCompanies use pack colours to manipulate consumers' perceptions of the taste, strength and health impacts of the cigarettes inside the packs, thereby altering their characteristics and effectively creating new products. In countries that do not require standardised packaging, regulators should consider colour equivalently to other changes in cigarette characteristics (eg, physical characteristics, ingredients, additives and flavourings) when making determinations about whether or not to permit new products on the market.
Project description:Accidental insertional activation of proto-oncogenes and potential vector mobilization pose serious challenges for human gene therapy using retroviral vectors. Comparative analyses of integration sites of different retroviral vectors have elucidated distinct target site preferences, highlighting vectors based on the alpharetrovirus Rous sarcoma virus (RSV) as those with the most neutral integration spectrum. To date, alpharetroviral vector systems are based mainly on single constructs containing viral coding sequences and intact long terminal repeats (LTR). Even though they are considered to be replication incompetent in mammalian cells, the transfer of intact viral genomes is unacceptable for clinical applications, due to the risk of vector mobilization and the potentially immunogenic expression of viral proteins, which we minimized by setting up a split-packaging system expressing the necessary viral proteins in trans. Moreover, intact LTRs containing transcriptional elements are capable of activating cellular genes. By removing most of these transcriptional elements, we were able to generate a self-inactivating (SIN) alpharetroviral vector, whose LTR transcriptional activity is strongly reduced and whose transgene expression can be driven by an internal promoter of choice. Codon optimization of the alpharetroviral Gag/Pol expression construct and further optimization steps allowed the production of high-titer self-inactivating vector particles in human cells. We demonstrate proof of principle for the versatility of alpharetroviral SIN vectors for the genetic modification of murine and human hematopoietic cells at a low multiplicity of infection.
