The impact of conspiracy beliefs on a targeted group: Perceived popularity of Jewish-targeted conspiracy beliefs elicits outgroup avoidant behaviours

In three studies with Jewish participants, we explored the consequences of intergroup conspiracy theories on those targeted. In Study 1 (N = 250), perceived Jewish conspiracy theory popularity was positively associated with intergroup threat and negatively associated with the closeness of contact with non-Jewish people. Study 2 (n = 194) employed an experimental design where Jewish participants were exposed to the idea that many (vs. few) non-Jewish people believe in Jewish conspiracy theories. A path model demonstrated that exposure to the many (vs. few) manipulation increased intergroup threat, which was then positively associated with emotional reactions. Intergroup anxiety and ingroup anger were then positively associated with avoidance, whilst ingroup anxiety was positively associated with approach tendencies. Study 3 (n = 201) used the same experimental design, and a path model revealed that conspiracy popularity increased intergroup threat, which, in turn, was positively associated with ingroup anger and anxiety. Ingroup anxiety was then associated with intentions to help ingroup members. Notably, conspiracy popularity rendered participants less likely to interact with a non-Jewish partner in a behavioural task. Our work provides evidence that conspiracy beliefs, especially when perceived to be widely held, are likely to significantly impact targeted ingroup members.

Impaired communication ability in SOX11 syndrome

BACKGROUND

Speech and language skills are important for social interaction and learning. This study characterised the communication abilities of verbal individuals with SOX11 syndrome using a standardised parent/carer questionnaire, the Children's Communication Checklist (CCC-2).

METHOD

Thirteen parent/carers of verbal individuals (aged 5-19 years) diagnosed with SOX11 syndrome completed the CCC-2. In order to contextualise findings, responses were compared to norms and to data from Noonan syndrome, a relatively well-known genetic diagnosis associated with communication impairment.

RESULTS

For all individuals, the CCC-2 composite score indicated significant communication difficulties. Language structure (speech, syntax, semantics and coherence), pragmatic language (inappropriate initiation, stereotyped language use of context and non-verbal communication) and autistic features (social relations and interests) scores were lower than typically developing norms. Subscale comparisons revealed relative difference in use of context compared to other pragmatic domains (stereotyped language and inappropriate initiation). Individual scores showed substantial variation, particularly in regard to language structure profile. Differences were more pronounced than for Noonan syndrome, specifically in domains of speech, syntax, non-verbal communication and social relations.

CONCLUSIONS

SOX11 syndrome is associated with communication impairment. It is important to assess communication abilities as part of the management of individuals with SOX11 syndrome and understand individual strengths and difficulties in order to provide targeted support.

Frequent gamblers' perceptions of the role of gambling marketing in their behaviour: An interpretative phenomenological analysis

This study explored how frequent gamblers perceive gambling marketing and the role they feel it has in their gambling behaviour. Ten frequent gamblers participated in semi-structured interviews oriented around their experiences of gambling marketing. An interpretative phenomenological analysis of the data led to three overarching themes: exploiting gambling marketing for personal gain; gambling marketing as a test of self-control; and safer gambling messages marketing perceived as ineffective. These themes encapsulated participants' views of gambling marketing as something they could take advantage of to increase their own gambling success. Marketing was also perceived as a test of self-control among self-identified experienced gamblers, although identified as a risk to those who are considered more vulnerable. Finally, safer gambling messages included within marketing was considered ineffective due to perceived insincerity and being seen as an 'afterthought' by marketers. In support of previous research, the current investigation highlights concerning narratives around self-control and perceived risk, as encapsulated within gambling marketing, and these are evident in the perceptions of frequent gamblers. Given gamblers' perceived lack of effectiveness of current safer gambling messages within marketing, future research should explore new avenues for safer gambling promotion.

Suprascapular nerve injury during robot-assisted radical prostatectomy: a case report

This case report aims to encourage teams to readjust the operating table during prolonged robotic cases, especially in those patients with a high body mass index. We present the case of a 59-year-old male who developed neuropathic pain involving the suprascapular nerve distribution following a prolonged robotic-assisted radical prostatectomy.

Ultrasound-guided motor unit scanning electromyography

INTRODUCTION/AIMS

Measuring the spatial dimensions of a single motor unit remains a challenging problem, and current techniques, such as scanning electromyography (EMG), tend to underestimate the true dimensions. In this study we aimed to estimate more accurately the dimensions of a single motor unit by developing a clinically applicable scanning EMG protocol that utilizes ultrasound imaging to visualize and target a transect through the center of a single motor unit.

METHODS

Single motor unit twitches in the tibialis anterior muscles of healthy volunteers were elicited via stimulation of the fibular nerve, visualized with ultrasound, and targeted with an intramuscular EMG electrode. The electrode was moved by hand in small steps through the motor unit territory. Ultrasound video output was synchronized to EMG capture, and the needle position was tracked at each step.

RESULTS

Eight recordings from six participants were collected. The technique was quick and easy to perform (mean time, 6.1 minutes) with reasonable spatial resolution (mean step size, 1.85 mm), yielding motor unit territory sizes between 1.53 and 14.65 mm (mean, 7.15 mm).

DISCUSSION

Ultrasound-guided motor unit scanning EMG is a quick and accurate method for obtaining a targeted motor unit transect. This combination of two readily available clinical tools provides insights into the dimensions and internal structure of the motor unit as a marker for neuromuscular conditions.

Understanding addiction in e-cigarette users – the EVAPE project

Background

Electronic cigarettes (e-cigarettes) are often advertised as a healthier option to combustible cigarettes and as smoking cessation aid. However, e-cigarettes are a growing health concern and their addictive potential remains to be fully understood. Within the EValuation of the Addictive Potential of E-cigarettes (EVAPE) project, we studied subjective and objective measures of addiction in relation to e-cigarette use.

Methods

This cross-sectional analysis was based on 832 participants of the first wave (2016) of England from the ITC Four Country Smoking and Vaping (4CV) Survey, who were using e-cigarettes daily or weekly for at least four months. Perceived addiction to e-cigarettes was categorised as very vs. not/somewhat addicted, and perceived addictiveness of e-cigarettes relative to combustible cigarettes as equally/more addictive vs. less addictive. Objective measures of addiction included urge to vape, time to first vape after waking, frequency of use, and used nicotine strength. We examined associations between these objective and subjective measures of addiction using multivariate logistic regression, adjusted for age, gender, education, and cigarette smoking.

Results

17.8% of participants reported feeling very addicted to e-cigarettes and 42.3% considered e-cigarettes equally/more addictive than combustible cigarettes. Those who felt very addicted had higher odds of regarding e-cigarettes as more addictive (OR 3.43 (95%-CI 2.29-5.19)). All objective measures of addiction were associated with higher perceived addiction, whereas only a shorter time to first vape was associated with perceived product addictiveness.

Conclusions

Subjective measures of addiction to e-cigarettes, in particular perceived addiction, correspond with objective measures. Understanding the addictive potential of e-cigarettes is the cornerstone for developing new strategies for prevention and treatment, and ultimately understanding their role from a public health perspective.

Key messages

Novel delivery of cellular therapy to reduce ischemia reperfusion injury in kidney transplantation

Ex vivo normothermic machine perfusion (NMP) of donor kidneys prior to transplantation provides a platform for direct delivery of cellular therapeutics to optimize organ quality prior to transplantation. Multipotent Adult Progenitor Cells (MAPC^® ) possess potent immunomodulatory properties that could minimize ischemia reperfusion injury. We investigated the potential capability of MAPC cells in kidney NMP. Pairs (5) of human kidneys, from the same donor, were simultaneously perfused for 7 hours. Kidneys were randomly allocated to receive MAPC treatment or control. Serial samples of perfusate, urine, and tissue biopsies were taken for comparison. MAPC-treated kidneys demonstrated improved urine output (P = .009), decreased expression of injury biomarker NGAL (P = .012), improved microvascular perfusion on contrast-enhanced ultrasound (cortex P = .019, medulla P = .001), downregulation of interleukin (IL)-1β (P = .050), and upregulation of IL-10 (P < .047) and Indolamine-2, 3-dioxygenase (P = .050). A chemotaxis model demonstrated decreased neutrophil recruitment when stimulated with perfusate from MAPC-treated kidneys (P < .001). Immunofluorescence revealed prelabeled MAPC cells in the perivascular space of kidneys during NMP. We report the first successful delivery of cellular therapy to a human kidney during NMP. Kidneys treated with MAPC cells demonstrate improvement in clinically relevant parameters and injury biomarkers. This novel method of cell therapy delivery provides an exciting opportunity to recondition organs prior to transplantation.

Transfer of Skills From Simulation Lab to Surgical Services: Impact of a Decade Long Laparoscopic Urology Surgical Course

OBJECTIVE

To investigate the impact of decade-long dedicated laparoscopic urology surgical skills course on the successful implementation of surgical services by the participants.

METHODS

A prospective database was maintained for all the participants in urological laparoscopic courses run by a single dedicated unit between January 2016 and December 2016. Data on various variables were collected using a follow-up validated questionnaire exploring speciality of clinical practice, challenges and need for additional training to establish clinical services, improvement in quality and frequency of laparoscopic courses. A subset of participants reported data of their outcomes in a national database available publically.

RESULTS

One hundred sixty one delegates were drawn from 18 countries attended laparoscopic skills courses during the study period of 10 years. Data were available for 154 (95.65%) participants. There were only 20 (20/154; 12.9%) responses to online website questionnaires despite 3 reminders. Further, follow-up through websites/telephonic contact/organizational contacts improved the response rate to 93% (143/154). Of the participants, 95% (135/143) felt that these courses should be continued, and they agreed to recommend them to their trainees in the future. More than 50% (81/143; 56.6%) of the participants performed laparoscopic/robotic surgery at various centers. Sixty two (62/143; 43.3%) did not pursue laparoscopic surgery as a career choice. Fifty six (56/81; 69%) participants were established laparoscopic surgeons were from the UK, and of them, 30 (30/56; 53.57%: 30/81; 37.04%) were established surgeons that contributed to publishing their results through professional organizations with the outcomes of all of these within normal ranges of their peers.

CONCLUSIONS

A dedicated laparoscopic urological surgery course run over a decade had a significant impact on the skills of participants, and most participants were able to establish clinical practice catering to a large proportion of the UK population as well as a few centers internationally.

Reported exposure to E-cigarette advertising and promotion in different regulatory environments: Findings from the International Tobacco Control Four Country (ITC-4C) Survey

Electronic cigarette (e-cigarette) advertising regulations differ across countries. This study examines how differences in e-cigarette advertising regulations influence exposure to e-cigarette advertising, and perceptions about what participants had seen and read about e-cigarettes. Data come from the ITC Four Country Survey (Canada [CA], United States [US], Australia [AU] and United Kingdom [UK]) carried out between August 2013 and March 2015 (n = 3460). In 2014, AU and CA had laws prohibiting the retail sale of e-cigarettes containing nicotine while the US and UK had no restrictions, although a voluntary agreement restricting advertising in the UK was introduced during fieldwork. Smokers and ex-smokers were asked whether in the last six months they had noticed e-cigarettes advertisements and received free samples/special offers (promotion), and about their perceptions (positive or otherwise) of what they had seen or read about e-cigarettes. Data were analyzed in 2017. US and UK participants were more likely to report that they had noticed e-cigarette advertisements and received promotions compared to CA or AU participants. For TV and radio advertisements, reported exposure was higher in US compared to UK. For all types of advertisements, reported exposure was higher in CA than AU. Overall, nearly half of AU (44.0%) and UK (47.8%) participants perceived everything they had seen and read about e-cigarettes to be positive, with no significant differences between AU and UK. Participants in countries with permissive e-cigarette advertising restrictions and less restrictive e-cigarette regulations were more likely to notice advertisements than participants in countries with more restrictive e-cigarette regulations.

Maintaining abstinence from smoking after a period of enforced abstinence - systematic review, meta-analysis and analysis of behaviour change techniques with a focus on mental health

BACKGROUND

Smoking prevalence is doubled among people with mental health problems and reaches 80% in inpatient, substance misuse and prison settings, widening inequalities in morbidity and mortality. As more institutions become smoke-free but most smokers relapse immediately post-discharge, we aimed to review interventions to maintain abstinence post-discharge.

METHODS

MEDLINE, EMBASE, PsycINFO, CINAHL and Web of Science were searched from inception to May 2016 and randomised controlled trials (RCTs) and cohort studies conducted with adult smokers in prison, inpatient mental health or substance use treatment included. Risk of bias (study quality) was rated using the Effective Public Health Practice Project Tool. Behaviour change techniques (BCTs) were coded from published papers and manuals using a published taxonomy. Mantel-Haenszel random effects meta-analyses of RCTs used biochemically verified point-prevalence smoking abstinence at (a) longest and (b) 6-month follow-up.

RESULTS

Five RCTs (n = 416 intervention, n = 415 control) and five cohort studies (n = 471) included. Regarding study quality, four RCTs were rated strong, one moderate; one cohort study was rated strong, one moderate and three weak. Most common BCTs were pharmacotherapy (n = 8 nicotine replacement therapy, n = 1 clonidine), problem solving, social support, and elicitation of pros and cons (each n = 6); papers reported fewer techniques than manuals. Meta-analyses found effects in favour of intervention [(a) risk ratio (RR) = 2.06, 95% confidence interval (CI) 1.30-3.27; (b) RR = 1.86, 95% CI 1.04-3.31].

CONCLUSION

Medication and/or behavioural support can help maintain smoking abstinence beyond discharge from smoke-free institutions with high mental health comorbidity. However, the small evidence base tested few different interventions and reporting of behavioural interventions is often imprecise.

Tobacco smoking is associated with psychotic experiences in the general population of South London

BACKGROUND

The association between cigarette smoking and psychosis remains unexplained, but could relate to causal effects in both directions, confounding by socioeconomic factors, such as ethnicity, or use of other substances, including cannabis. Few studies have evaluated the association between cigarettes and psychotic experiences (PEs) in diverse, inner-city populations, or relationships with number of cigarettes consumed.

METHODS

We assessed associations and dose-response relationships between cigarette smoking and PEs in a cross-sectional survey of household residents (n = 1680) in South East London, using logistic regression to adjust for cannabis use, other illicit substances, and socioeconomic factors, including ethnicity.

RESULTS

We found association between any PEs and daily cigarette smoking, which remained following adjustment for age, gender, ethnicity, cannabis and use of illicit stimulant drugs (fully adjusted odds ratio 1.47, 95% confidence interval 1.01-2.15). Fully adjusted estimates for the association, and with number of PEs, increased with number of cigarettes smoked daily, implying a dose-response effect (p = 0.001 and <0.001, respectively). Odds of reporting any PEs in ex-smokers were similar to never-smokers.

CONCLUSIONS

In this diverse epidemiological sample, association between smoking and PEs was not explained by confounders such as cannabis or illicit drugs. Daily cigarette consumption showed a dose-response relationship with the odds of reporting PEs, and of reporting a greater number of PEs. There was no difference in odds of reporting PEs between ex-smokers and never-smokers, raising the possibility that the increase in PEs associated with smoking may be reversible.

The 67P/Churyumov-Gerasimenko observation campaign in support of the Rosetta mission

We present a summary of the campaign of remote observations that supported the European Space Agency's Rosetta mission. Telescopes across the globe (and in space) followed comet 67P/Churyumov-Gerasimenko from before Rosetta's arrival until nearly the end of the mission in September 2016. These provided essential data for mission planning, large-scale context information for the coma and tails beyond the spacecraft and a way to directly compare 67P with other comets. The observations revealed 67P to be a relatively 'well-behaved' comet, typical of Jupiter family comets and with activity patterns that repeat from orbit to orbit. Comparison between this large collection of telescopic observations and the in situ results from Rosetta will allow us to better understand comet coma chemistry and structure. This work is just beginning as the mission ends-in this paper, we present a summary of the ground-based observations and early results, and point to many questions that will be addressed in future studies.This article is part of the themed issue 'Cometary science after Rosetta'.

Group-centric attitudes mediate the relationship between need for closure and intergroup hostility

A model of the relationship between need for closure (NFC) and intergroup hostility was tested in four studies. According to the model, heightened NFC promotes glorification of the ingroup which fosters support for extreme measures against the group’s perceived enemies. In a parallel process, high level of NFC induces perceptions of ingroup victimhood, which also adds support for aggressive actions toward rival outgroups. In the first two studies, conducted in Palestine’s West Bank (Study 1) and in the United States (Study 2), NFC promoted a greater sense of moral entitlement to engage in violence against the outgroup, and this was mediated by perceived ingroup victimhood. The subsequent two studies tested the full hypothesized parallel mediation model among students in Northern Ireland (Study 3) and Jewish-Israelis (Study 4). Results largely supported the proposed model. Findings are discussed in relation to additional evidence linking NFC to phenomena of intergroup hostility.

The Shadows of the Past

We examined associations between two orientations based on historical group trauma, a form of enduring group victimhood (Perpetual Ingroup Victimhood Orientation [PIVO]) and the belief that one’s group might itself become a victimizer (Fear of Victimizing [FOV]), and attitudes, cognitions, and emotions related to intergroup conflicts. PIVO was positively and FOV was negatively related to aggressive attitudes and emotions toward the outgroup (Studies 1a-1c, Israeli–Palestinian conflict), and to the attribution of responsibility for a series of hostilities to the outgroup (Study 3, Israeli–Palestinian conflict). PIVO was negatively and FOV positively related to support for forgiveness and reconciliation (Study 2, Northern Ireland conflict). In Experimental Study 4, FOV predicted greater accuracy in remembering harm, regardless of victims’ group identity, whereas PIVO was associated with reduced accuracy only when victims were Palestinians (outgroup members). Taken together, these findings indicate that both orientations have a significant impact on intergroup conflicts and their resolution.

Negligence Claims for Treatment of Neurological Disease: Cases from the Medical and Dental Defence Union of Scotland

There is no detailed description of negligence claims made against clinicians treating neurological disease in the U.K. Here negligence claims concerning treatment of neurological disease, which were handled by the Medical and Dental Defence Union of Scotland (MDDUS), were audited. Sixty-two cases were identified; in 38 cases the clinician was a neurosurgeon, in 16 a neurologist and in 8 a General Practitioner (G.P). The most common conditions were inter-vertebral disc disease and neoplasia, the most common misadventure was improper performance of procedure and most of the cases resulted in severe permanent disability.

Twitter Influence on UK Vaccination and Antiviral Uptake during the 2009 H1N1 Pandemic

OBJECTIVE

Information exchange via Twitter and other forms of social media make public health communication more complex as citizens play an increasingly influential role in shaping acceptable or desired health behaviors. Taking the case of the 2009-2010 H1N1 pandemic, we explore in detail the dissemination of H1N1-related advice in the UK through Twitter to see how it was used to discourage or encourage vaccine and antiviral uptake.

METHODS

In three stages we conducted (1) an analysis of general content, retweeting patterns, and URL sharing, (2) a discourse analysis of the public evaluation of press releases and (3) a template analysis of conversations around vaccine and antiviral uptake, using Protection Motivation Theory (PMT) as a way of understanding how the public weighed the costs and benefits.

RESULTS

Network analysis of retweets showed that information from official sources predominated. Analysing the spread of significant messages through Twitter showed that most content was descriptive but there was some criticism of health authorities. A detailed analysis of responses to press releases revealed some scepticism over the economic beneficiaries of vaccination, that served to undermine public trust. Finally, the conversational analysis showed the influence of peers when weighing up the risks and benefits of medication.

CONCLUSION

Most tweets linked to reliable sources, however Twitter was used to discuss both individual and health authority motivations to vaccinate. The PMT framework describes the ways individuals assessed the threat of the H1N1 pandemic, weighing this against the perceived cost of taking medication. These findings offer some valuable insights for social media communication practices in future pandemics.

The effectiveness of tobacco control television advertisements in increasing the prevalence of smoke-free homes

BACKGROUND

There is considerable evidence that tobacco control mass media campaigns can change smoking behaviour. In the UK, campaigns over the last decade have contributed to declines in smoking prevalence and been associated with falls in cigarette consumption among continuing smokers. However, it is less evident whether such campaigns can also play a role in changing smokers' behaviour in relation to protecting others from the harmful effects of their smoking in the home. We investigated whether exposure to English televised tobacco control campaigns, and specifically campaigns targeting second hand smoking, is associated with smokers having a smoke-free home.

METHODS

We used repeated cross-sectional national survey data on 9872 households which participated in the Health Survey for England between 2004 and 2010, with at least one adult current smoker living in the household. Exposure to all government-funded televised tobacco control campaigns, and to those specifically with a second hand smoking theme, was quantified in Gross Rating Points (GRPs), an average per capita measure of advert exposure where 100 GRPs indicates 100 % of adults exposed once or 50 % twice. Our outcome was self-reported presence of a smoke-free home (where no one smokes in the home on most days). Analysis used generalised additive models, controlling for individual factors and temporal trends.

RESULTS

There was no association between monthly televised campaigns overall and the probability of having a smoke-free home. However, exposure to campaigns specifically targeting second hand smoke was associated with increased odds of a smoke-free home in the following month (odds ratio per additional 100 GRPs, 1.07, 95 % CI 1.01 to 1.13), though this association was not seen at other lags. These effects were not modified by socio-economic status or by presence of a child in the home.

CONCLUSIONS

Our findings provide tentative evidence that mass media campaigns specifically focussing on second hand smoke may be effective in reducing smoking in the home, and further evaluation of campaigns of this type is needed. General tobacco control campaigns in England, which largely focus on promoting smoking cessation, do not impact on smoke-free homes over and above their direct effect at reducing smoking.

Effectiveness of tobacco control television advertisements with different types of emotional content on tobacco use in England, 2004-2010

AIM

To examine the effects of tobacco control television advertisements with positive and negative emotional content on adult smoking prevalence and cigarette consumption.

DESIGN

Analysis of monthly cross-sectional surveys using generalised additive models.

SETTING

England.

PARTICIPANTS

60 000 adults aged 18 years or over living in England and interviewed in the Opinions and Lifestyle Survey from 2004 to 2010.

MEASUREMENTS

Current smoking status, daily cigarette consumption, tobacco control gross rating points (GRPs-a measure of per capita advertising exposure), cigarette costliness, concurrent tobacco control policies, sociodemographic variables.

RESULTS

After adjusting for cigarette costliness, other tobacco control policies and individual characteristics, we found that a 400-point increase in positive emotive GRPs was associated with 7% lower odds of smoking (odds ratio (OR) 0.93, 95% CI 0.87 to 0.98) 1 month later and a similar increase in negative emotive GRPs was significantly associated with 4% lower odds of smoking (OR 0.96, 95% CI 0.92 to 0.999) 2 months later. An increase in negative emotive GRPs from 0 to 400 was also associated with a significant 3.3% (95% CI 1.1 to 5.6) decrease in average cigarette consumption. There was no evidence that the association between positive emotive GRPs and the outcomes differed depending on the intensity of negative emotive GRPs (and vice versa).

CONCLUSIONS

This is the first study to explore the effects of campaigns with different types of emotive content on adult smoking prevalence and consumption. It suggests that both types of campaign (positive and negative) are effective in reducing smoking prevalence, whereas consumption among smokers was only affected by campaigns evoking negative emotions.

Reconstructing apology: David Cameron's Bloody Sunday apology in the press

While there is an acknowledgement in apology research that political apologies are highly mediated, the process of mediation itself has lacked scrutiny. This article suggests that the idea of reconstruction helps to understand how apologies are mediated and evaluated. David Cameron's apology for Bloody Sunday is examined to see how he constructs four aspects of apology: social actors, consequences, categorization, and reasons. The reconstruction of those aspects by British, Unionist, and Nationalist press along with reconstructions made by soldiers in an online forum are considered. Data analysis was informed by thematic analysis and discourse analysis which helped to explore key aspects of reconstruction and how elements of Cameron's apology are altered in subsequent mediated forms of the apology. These mediated reconstructions of the apology allowed their authors to evaluate the apology in different ways. Thus, in this article, it is suggested that the evaluation of the apology by different groups is preceded by a reconstruction of it in accordance with rhetorical goals. This illuminates the process of mediation and helps to understand divergent responses to political apologies.

Good practices for the prevention of alcohol harmful use amongst the elderly in Europe, the VINTAGE project

INTRODUCTION

There is a lack of information about initiatives aimed at preventing the harmful effects of alcohol amongst the elderly.

OBJECTIVES

One of the objectives of the VINTAGE study was to collect the initiatives carried out in Europe and review the published grey literature about this topic.

METHODS

Email-based survey addressed to researchers, professionals and policymakers, and internet search of grey literature.

RESULTS

Three hundred nine contacts were finally made, and 21 of the 36 collected initiatives were considered as useful in preventing the harmful use of alcohol amongst the elderly. Out of the about 2900 references identified 96 were classified as relevant.

CONCLUSIONS

Despite a growing interest, alcohol use in the elderly is not yet perceived as a major issue for prevention.

Alcohol and older people. The European project VINTAGE: good health into older age. Design, methods and major results

OBJECTIVES

The European project VINTAGE - Good Health Into Older Age aims at filling the knowledge gap and building capacity on alcohol and the elderly, encouraging evidence- and experience-based interventions.

METHODS

Systematic review of scientific literature on the impact of alcohol on older people; ad hoc survey and review of grey literature to collect EU examples of good practices for prevention; dissemination of findings to stakeholders involved in the field of alcohol, aging or public health in general.

RESULTS

Design and procedures of the VINTAGE project are described, providing also an outline of major results, with particular attention to those related to the dissemination activity.

CONCLUSIONS

Much more information and research is needed. This issue should be part of both alcohol and healthy ageing policies.

Mediation analysis of the association between use of NRT for smoking reduction and attempts to stop smoking

OBJECTIVES

Use of nicotine replacement therapy (NRT) for smoking reduction (SR) is linked to higher quit attempt rates than SR without NRT. This study aimed to assess the possible mediating roles of confidence in ability to quit, enjoyment of smoking and motivation to quit in this association.

DESIGN

Cross-sectional survey.

MAIN OUTCOME MEASURES

Smokers were asked if they were currently attempting SR, and if they were, whether they were using NRT. Motivation to stop, enjoyment of smoking, confidence in ability to stop, and previous quit attempts, were also assessed.

RESULTS

There was no evidence that confidence in ability to quit or enjoyment of smoking mediated the association between the use of NRT for SR and attempts to quit. Only motivation to stop partially mediated between the use of NRT for SR and attempts to stop (indirect effect: odds ratio 1.08, p < 0.001).

CONCLUSION

Although this study is limited by its cross-sectional design, the findings point towards the possibility that the use of NRT to aid SR may promote attempts to stop through increasing motivation to quit but not by increasing confidence or by reducing enjoyment of smoking. Longitudinal studies are required to draw firmer conclusions about the possible mediating effects of motivation to quit.

Progressive brain iron accumulation in neuroferritinopathy measured by the thalamic T2* relaxation rate

Neuroferritinopathy is an autosomal dominant extrapyramidal movement disorder, caused by FTL gene mutations. Iron decreases the MR T2* decay time, therefore increasing the R2* (R2* = 1 /T2*), which correlates with brain tissue iron content. 3T structural and quantitative MR imaging assessment of R2* in 10 patients with neuroferritinopathy demonstrated a unique pattern of basal ganglia cavitation involving the substantia nigra in older patients and increasing thalamic R2* signal intensity detectable during 6 months. Increasing R2* signal intensity in the thalamus correlated with progression on a clinical rating scale measuring dystonia severity. Thalamic R2* signal intensity is a clinically useful method of objectively tracking disease progression in this form of neurodegeneration with brain iron accumulation.

Promoter mutation is a common variant in GJC2-associated Pelizaeus-Merzbacher-like disease

Pelizaeus-Merzbacher-like disease (PMLD) is a clinically and genetically heterogeneous neurological disorder of cerebral hypomyelination. It is clinically characterised by early onset (usually infantile) nystagmus, impaired motor development, ataxia, choreoathetoid movements, dysarthria and progressive limb spasticity. We undertook autozygosity mapping studies in a large consanguineous family of Pakistani origin in which affected children had progressive lower limb spasticity and features of cerebral hypomyelination on MR brain imaging. SNP microarray and microsatellite marker analysis demonstrated linkage to chromosome 1q42.13-1q42.2. Direct sequencing of the gap junction protein gamma-2 gene, GJC2, identified a promoter region mutation (c.-167A>G) in the non-coding exon 1. The c.-167A>G promoter mutation was identified in a further 4 individuals from two families (who were also of Pakistani origin) with clinical and radiological features of PMLD in whom previous routine diagnostic screening of GJC2 had been reported as negative. A common haplotype was identified at the GJC2 locus in the three mutation-positive families, consistent with a common origin for the mutation and likely founder effect. This promoter mutation has only recently been reported in GJC2-PMLD but it has been postulated to affect the binding of the transcription factor SOX10 and appears to be a prevalent mutation, accounting for ~29% of reported patients with GJC2-PMLD. We propose that diagnostic screening of GJC2 should include sequence analysis of the non-coding exon 1, as well as the coding regions to avoid misdiagnosis or diagnostic delay in suspected PMLD.

Use of nicotine replacement therapy for smoking reduction and during enforced temporary abstinence: a national survey of English smokers

AIMS

To assess the prevalence of nicotine replacement therapy (NRT) use for smoking reduction (SR) and temporary abstinence (TA), the association between the two and the strength of the association between NRT use for SR or TA and socio-demographic characteristics, cigarette consumption and past quit attempts.

DESIGN

Cross-sectional monthly surveys.

SETTING

England.

PARTICIPANTS

A total of 11, 414 smokers.

MEASUREMENTS

Participants were asked (i) whether they were reducing the amount they smoked: if so, whether they used NRT; and (ii) whether they used NRT for TA. Demographic characteristics, daily cigarette consumption and whether a quit attempt had been made in the past 12 months were also assessed.

FINDINGS

Of the participants, 56% were attempting SR, 14% were using NRT for SR and 14% were using NRT for TA. Use of NRT for SR and TA were highly correlated. The nicotine patch was the most commonly used form of NRT. The use of NRT for SR, compared with unassisted SR, was more common among older smokers, while the use of NRT for TA was more common among women. Cigarette consumption was higher in those using NRT for SR than those attempting SR without NRT. The use of NRT for SR and TA was associated positively with past quit attempts.

CONCLUSIONS

Nicotine replacement therapy use for smoking reduction and temporary abstinence is common in England. The use of NRT for SR and TA does not appear to be associated with lower cigarette consumption relative to SR or TA without NRT, but is associated with a higher rate of past quit attempts.

Smoking uptake and prevalence in Ghana

BACKGROUND

Developing countries are at high risk of epidemic increases in tobacco smoking, but the extent of this problem is not clearly defined because few collect detailed smoking data. We have surveyed tobacco smoking in the Ashanti region of Ghana, a rapidly developing African country with a long-established tobacco industry.

METHODS

We took a random sample of 30 regional census enumeration areas, each comprising about 100 households, and a systematic sample of 20 households from each. These were visited, a complete listing of residents obtained and questionnaire interviews on current and past smoking, age at smoking uptake, sources of cigarettes and other variables carried out in all consenting residents aged 14 or over.

RESULTS

Of 7096 eligible individuals resident in the sampled households, 6258 (88%; median age 31 (range 14-105) years; 64% female) participated. The prevalence of self-reported current smoking (weighted for gender differences in response) was 3.8% (males 8.9%, females 0.3%) and of ever smoking 9.7% (males 22.0%, females 1.2%). Smoking was more common in older people, those of Traditionalist belief, those of low educational level, the unemployed and the less affluent. Smokers were more likely to drink alcohol and to have friends who smoke. About 10% of cigarettes were smuggled brands. About a third of smokers were highly or very highly dependent.

CONCLUSIONS

Despite rapid economic growth and a sustained tobacco industry presence, smoking prevalence in Ghana is low, particularly among younger people. This suggests that progression of an epidemic increase in smoking has to date been avoided.

Impact of graphic and text warnings on cigarette packs: findings from four countries over five years

OBJECTIVES

To examine the impact of health warnings on smokers by comparing the short-term impact of new graphic (2006) Australian warnings with: (i) earlier (2003) United Kingdom larger text-based warnings; (ii) and Canadian graphic warnings (late 2000); and also to extend our understanding of warning wear-out.

METHODS

The International Tobacco Control Policy Evaluation Survey (ITC Project) follows prospective cohorts (with replenishment) of adult smokers annually (five waves: 2002-2006), in Canada, United States, UK and Australia (around 2000 per country per wave; total n = 17 773). Measures were of pack warning salience (reading and noticing); cognitive responses (thoughts of harm and quitting); and two behavioural responses: forgoing cigarettes and avoiding the warnings.

RESULTS

All four indicators of impact increased markedly among Australian smokers following the introduction of graphic warnings. Controlling for date of introduction, they stimulated more cognitive responses than the UK (text-only) changes, and were avoided more, did not significantly increase forgoing cigarettes, but were read and noticed less. The findings also extend previous work showing partial wear-out of both graphic and text-only warnings, but the Canadian warnings have more sustained effects than UK ones.

CONCLUSIONS

Australia's new health warnings increased reactions that are prospectively predictive of cessation activity. Warning size increases warning effectiveness and graphic warnings may be superior to text-based warnings. While there is partial wear-out in the initial impact associated with all warnings, stronger warnings tend to sustain their effects for longer. These findings support arguments for governments to exceed minimum FCTC requirements on warnings.

Smoking in Ghana: a review of tobacco industry activity

Background:

African countries are a major potential market for the tobacco industry, and the smoking epidemic is at various stages of evolution across the continent. Ghana is an African country with a low prevalence of smoking despite an active tobacco industry presence for over 50 years. This study explores potential reasons for this apparent lack of industry success.

Objective:

To explore the history of tobacco industry activity in Ghana and to identify potential reasons for the current low prevalence of smoking.

Methods:

A search was made of tobacco industry archives and other local sources to obtain data relevant to marketing and consumption of tobacco in Ghana.

Findings:

British American Tobacco, and latterly the International Tobacco Company and its successor the Meridian Tobacco Company, have been manufacturing cigarettes in Ghana since 1954. After an initial sales boom in the two decades after independence in 1957, the sustained further increases in consumption typical of the tobacco epidemic in most countries did not occur. Possible key reasons include the taking of tobacco companies into state ownership and a lack of foreign exchange to fund tobacco leaf importation in the 1970s, both of which may have inhibited growth at a key stage of development, and the introduction of an advertising ban in 1982. BAT ceased manufacturing cigarettes in Ghana in 2006.

Conclusion:

The tobacco industry has been active in Ghana for over 50 years but with variable success. The combination of an early advertising ban and periods of unfavourable economic conditions, which may have restricted industry growth, are likely to have contributed to the sustained low levels of tobacco consumption in Ghana to date.

How do different cigarette design features influence the standard tar yields of popular cigarette brands sold in different countries?

OBJECTIVES

To examine the associations among cigarette design features and tar yields of leading cigarette brands sold in the United States, Canada, Australia and the United Kingdom.

METHODS

Government reports and numbers listed on packs were used to obtain data on International Organization for Standardization (ISO)/Federal Trade Commission (FTC) yields for the tar of 172 cigarette varieties sold in the United States, Canada, Australia and the United Kingdom. We used standardised methods to measure the following 11 cigarette design parameters: filter ventilation, cigarette pressure drop, filter pressure drop, tobacco rod length, filter length, cigarette diameter, tipping paper length, tobacco weight, filter weight, rod density and filter density.

RESULTS

Filter ventilation was found to be the predominant design feature accounting for the variations between brands in ISO/FTC tar yields in each of the four countries. After accounting for filter ventilation, design parameters such as overwrap length, tobacco weight and rod density played comparatively minor roles in determining tar yields.

CONCLUSIONS

Variation in ISO/FTC tar yields are predicted by a limited set of cigarette design features, especially filter ventilation, suggesting that governments should consider mandatory disclosure of cigarette design parameters as part of comprehensive tobacco product regulations.

The feasibility of measuring puffing behaviour in roll-your-own cigarette smokers

BACKGROUND/OBJECTIVE

Despite the increase in roll-your-own (RYO) cigarette consumption in many countries, very little is known about RYO smokers. In order to estimate the health risks inherent in RYO use, it is important to assess exposure to tobacco toxins in this group. Exposure is determined by a number of factors, including puffing behaviour, but so far this issue has not been addressed among RYO smokers. This study sought both to determine the feasibility of measuring puffing behaviour in this group, its reliability and validity, and to characterise puffing behaviour among RYO smokers compared with smokers of factory-made (FM) cigarettes.

METHODS

At two visits, 24 hours apart, 131 FM and 29 RYO cigarette smokers provided saliva samples that were assayed for cotinine, a measure of nicotine intake and thus smoke exposure. Self-reported puffing behaviour of participants, as well as their demographic and smoking characteristics were also assessed. At the end of the first visit, smokers were shown how to use a portable smoking topography machine that measures puffing behaviour, the CReSSmicro, and asked to smoke all cigarettes with this machine until the second visit, when participants were asked to provide feedback on using the device.

RESULTS

Both RYO and FM cigarette smokers reported that the CReSSmicro was easy to use; however, RYO cigarette smokers were more likely to have missing data, to reduce cigarette consumption and to indicate a change in their puffing behaviour because of the device. Machine-determined puffing behaviour was equally stable over time in both groups with similar ability to predict exposure; cotinine levels were related to machine but not to self-reported puffing parameters. Overall, RYO smokers appeared to puff cigarettes less hard but for longer than FM cigarette smokers.

CONCLUSION

The measurement of puffing behaviour using a topography device is feasible but less practicable for RYO than FM cigarette smokers. Puffing parameters show comparable reliability and validity for both groups of smokers and reveal some differences in smoking topography dependent on the type of cigarette smoked.
