ABSTRACT

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 5-19Ā 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.

ABSTRACT

Low temperature in winter depresses rates of photosynthesis, which, in evergreen plants, can exacerbate imbalances between light absorption and photochemical light use. Damage that could result from increased excess light absorption is minimized by the conversion of excitation energy to heat in a process known as energy dissipation, which involves the de-epoxidized carotenoids of the xanthophyll cycle. Overwintering evergreens employ sustained forms of energy dissipation observable even after lengthy periods of dark acclimation. Whereas most studies of photoprotective energy dissipation examine one or a small number of species; here, we measured the levels of sustained thermal energy dissipation of seventy conifer taxa growing outdoors under common-garden conditions at the Red Butte Garden in Salt Lake City, Utah, U.S.A. (forty nine taxa were also sampled for needle pigment content). We observed an extremely wide range of wintertime engagement of sustained energy dissipation; the percentage decrease in dark-acclimated photosystem II quantum efficiency from summer to winter ranged from 6 to 95%. ĆÆĀ»ĀæOf the many pigment-based parameters measured, the magnitude of the seasonal decrease in quantum efficiency was most closely associated with the seasonal increase in zeaxanthin content expressed on a total chlorophyll basis, which explained only slightly more than one-third of the variation. We did not find evidence for a consistent wintertime decrease in needle chlorophyll content. Thus, the prevailing mechanism for winter decreases in solar-induced fluorescence emitted by evergreen forests may be decreases in fluorescence quantum yield, and wintertime deployment of sustained energy dissipation likely underlies this effect.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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 (nĆ¢Ā€ĀÆ=Ć¢Ā€ĀÆ3460). 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.

ABSTRACT

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.

ABSTRACT

WHAT IS KNOWN AND OBJECTIVE: Metformin is the only oral antihyperglycemic agent approved for use in adolescents with type 2 diabetes mellitus (T2DM). There are reports of metformin used to treat conditions such as obesity, hyperinsulinemia, prediabetes, metabolic syndrome and polycystic ovarian syndrome (PCOS). It is important to understand metformin prescription patterns and underlying diagnoses in adolescents as it can provide estimates of the extent of on-label (i.e. treatment of T2DM) and off-label use of metformin in this population. Our study sought to assess metformin prescription patterns among US adolescents from 2009 to 2013. METHODS: Data from the National Disease and Therapeutic Index (NDTI) database, the MarketScan(Ā®) Commercial Claims and Encounters database and the Multi-State Medicaid database were analysed. The proportion of diagnoses associated with metformin that was recommended during a clinical visit was identified in the NDTI database. In the MarketScan(Ā®) Commercial and Medicaid databases, adolescents with at least one metformin prescription with Ā±6 months continuous enrolment from the date of the index metformin prescription were included in the analyses. All diagnosis and procedure codes were extracted within Ā±6 months of the index metformin prescription. The proportion of T2DM was calculated irrespective of any other medical conditions, whereas all other prespecified conditions were classified as positive only if no concurrent T2DM diagnosis codes were present. RESULTS AND DISCUSSION: In the NDTI database, the most common diagnoses associated with metformin use were diabetes (34Ā·9%), followed by metabolic syndrome (20Ā·9%), PCOS (17Ā·2%) and obesity (6Ā·5%). In the MarketScan(Ā®) Commercial database, T2DM was the most common diagnosis among girls aged 10-14 years (22Ā·8-23Ā·6%), boys aged 10-14 years (20Ā·5-24Ā·5%) and boys aged 15-19 years (37Ā·1-43Ā·1%), whereas PCOS (24Ā·1-28Ā·3%) was the most common diagnosis among girls aged 15-19 years. In the Medicaid database, T2DM was the most common diagnosis among all four groups and the proportions were higher than their counterparts in the Commercial database. WHAT IS NEW AND CONCLUSION: Analyses from three separate US data sources suggest that off-label prescribing of metformin is common among US adolescents aged 10-19 years. To avoid potential overestimation, caution should be exercised when utilizing metformin prescription as a proxy measure to estimate the burden of T2DM in adolescents.

ABSTRACT

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.

ABSTRACT

OBJECTIVES: The recent growth in the market for electronic cigarettes (e-cigarettes) has led to concerns over their use by young people. It is therefore important to examine trends in the perception and use of e-cigarettes and conventional cigarettes in this group. STUDY DESIGN: Two-wave cross-sectional survey design. METHODS: Young people aged 11-18 in Great Britain were surveyed online by YouGov in 2013 and 2014. Use of e-cigarettes, together with perceived health harms and intention to use were assessed and compared in relation to cigarette smoking history, age and gender. RESULTS: Ever-use of e-cigarettes increased significantly from 4.6% (95% CI 3.8-5.7) in 2013 to 8.2% (95% CI 7.0-9.6) in 2014. Monthly or more use of e-cigarettes increased from 0.9% (95% CI 0.5-1.5) to 1.7 (1.2-2.4), but remained rare in never-smokers at under 0.2%. The proportion of young people who perceived e-cigarettes to be less harmful to users than cigarettes fell from 73.4% (95% CI 71.0-75.8) to 66.9% (95% CI 64.5-69.2), while the proportion who considered e-cigarettes to cause similar levels of harm increased from 11.8% (95% CI 10.0-13.5) to 18.2% (95% CI 16.3-20.1). Of the 8.2% of e-cigarette ever-users in 2014, 69.8% (95% CI 62.2%-77.3%) had smoked a cigarette prior to using an e-cigarette, while 8.2% (95% CI 4.1%-12.2%) first smoked a cigarette after e-cigarette use. CONCLUSIONS: A growing proportion of young people in Great Britain believe e-cigarettes are as harmful as smoking tobacco. Use of e-cigarettes by young people is increasing, but is largely confined to those who smoke.

ABSTRACT

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.

ABSTRACT

BACKGROUND: The carcinogenicity of chewing tobacco is well established. It is predominantly used by the South Asian community in England. Little is known about the accessibility of the products available for use in England. METHODS: Wards with high proportions or numbers of residents from the South Asian community were identified using 2001 Census data. Within each ward product purchasers identified retail outlets and purchased chewing tobacco products from them. RESULTS: Chewing tobacco products were found in a broad variety of premises in all but one ward, and were easily accessible. Ninety-eight products were identified and purchased with a mean price of pound1.82. Of the ninety four pre-packaged products purchased only 15% (95% CI: 8%, 22%) complied with legal health warning requirements. CONCLUSION: The study indicates the need to improve compliance with legal controls and enforcement to protect the South Asian community from health risks associated with chewing tobacco products.

ABSTRACT

BACKGROUND: Photodynamic therapy (PDT) is a popular treatment for nonmelanoma skin cancer with clearance rates of between 70% and 100%. Although reported to have a superior cosmetic outcome, the inconvenience of hospital visits and discomfort during therapy are considered drawbacks. OBJECTIVES: To present an open pilot study of a low-irradiance, potentially disposable, lightweight, organic light-emitting diode (OLED), which is an area-emitting light source (2 cm diameter), suitable for ambulatory PDT. METHODS: Twelve patients with Bowen's disease (eight) and superficial basal cell carcinoma (four) < 2 cm in diameter were recruited into the study following histological confirmation of the diagnosis. Two treatments (45-60 J cm(-2) red light, 550-750 nm, peak 620 nm, irradiance 5 mW cm(-2)) were administered 1 month apart following application of aminolaevulinic acid for 4 h. RESULTS: At the 12-month follow-up, seven of the 12 patients remained clear, with four of the nonresponders demonstrating peripheral margin failure. Patients were scored for pain during and immediately after treatment using the numerical rating scale (NRS; 1-10). All 12 subjects scored pain as < 2 using the NRS (median score 1). In contrast, a similar cohort of 50 consecutive patients from our routine PDT clinic (Aktilite inorganic LED source; 75 J cm(-2), irradiance 80 mW cm(-2)) scored a median of 6 on the NRS. CONCLUSIONS: Pain and inconvenience are practical barriers to the use of conventional PDT. This pilot study suggests that OLED-PDT is less painful than conventional PDT with the added advantage of being lightweight, and therefore has the potential for more convenient 'home PDT'. These results need to be validated in larger studies.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.
