Mapping Australian public opinion on alcohol policies in the new millennium

Introduction and Aims. Drawing on 16 items in the 2004 National Drug Strategy Household Survey (NDSHS), the paper explores the degree to which Australian public opinion towards different alcohol policies cohere or diverge, and the social location of support for and resistance to more restrictive alcohol controls. Variations in support for particular policies by demographic groups, across states and territories and among those with difference drinking patterns are explored. The extent and direction in which attitudes have changed over time was determined. Design and Methods. Sixteen items from the 2004 NDSHS were subjected to factor analysis. Both a single factor and a four‐factor solution were derived and became the dependent variables for state/territory comparisons and multiple regression analyses determining the predictive power of respondents demographics and drinking behaviour. Trends over time in alcohol policy attitudes used the 1993, 1995, 1998, 2001 and 2004 NDSHS. Results. More severe penalties against drink driving and stricter laws against serving customers who were drunk had the strongest support while policies that controlled accessibility to alcohol such as reducing trading hours received the least support. For all policies support was greater among females, older respondents and those drinking less. The individual's drinking pattern was as strong, and in some cases a stronger predictor of support than gender and age. Discussion and Conclusions. While support for the majority of the alcohol policies decreased over the 11‐year period since 1993, attitudes may be influenced and changed over a shorter period of time.[Wilkinson C, Room R, Livingston M.

Categorization of fragrance contact allergens for prioritization of preventive measures: clinical and experimental data and consideration of structure–activity relationships

Contact allergy to fragrances is still relatively common, affecting ～ 16% of patients patch tested for suspected allergic contact dermatitis, considering all current screening allergens. The objective of the review is to systematically retrieve, evaluate and classify evidence on contact allergy to fragrances, in order to arrive at recommendations for targeting of primary and secondary prevention. Besides published evidence on contact allergy in humans, animal data (local lymph node assay), annual use volumes and structure–activity relationships (SARs) were considered for an algorithmic categorization of substances as contact allergens. A total of 54 individual chemicals and 28 natural extracts (essential oils) can be categorized as established contact allergens in humans, including all 26 substances previously identified as contact allergens (SCCNFP/0017/98). Twelve of the 54 individual chemicals are considered to be of special concern, owing to the high absolute number of reported cases of contact allergy (> 100). Additionally, 18 single substances and one natural mixture are categorized as established contact allergens in animals. SARs, combined with limited human evidence, contributed to the categorization of a further 26 substances as likely contact allergens. In conclusion, the presence of 127 single fragrance substances and natural mixtures should, owing to their skin sensitizing properties, be disclosed, for example on the label. As an additional preventive measure, the maximum use concentration of 11 substances of special concern should be limited to 100 ppm. The substance hydroxyisohexyl 3‐cyclohexene carboxaldehyde and the two ingredients chloroatranol and atranol in the natural extracts Evernia prunastri and Evernia furfuracea should not be present in cosmetic products.     

Publics and biobanks: Pan-European diversity and the challenge of responsible innovation

This article examines public perceptions of biobanks in Europe using a multi-method approach combining quantitative and qualitative data. It is shown that public support for biobanks in Europe is variable and dependent on a range of interconnected factors: people''s engagement with biobanks; concerns about privacy and data security, and trust in the socio-political system, key actors and institutions involved in biobanks. We argue that the biobank community needs to acknowledge the impact of these factors if they are to successfully develop and integrate biobanks at a pan-European level.     

Post-aggression suicide under the influence of new psychoactive substances AMB–FUBINACA and U-47700

The objective of the present study was the development and validation of the method for determining AMB-FUBINACA and its metabolite - AMB-FUBINACA O-desmethyl acid – in blood samples, followed by verification of the method in toxicological judicial and forensic medicine practice employing the example of post-aggression suicide. Most likely in consequence of development of adverse effects resulting in psychotic symptoms, a male being under the influence of the synthetic cannabinoid AMB-FUBINACA and the new synthetic opioid U-47700, mortally wounded his female partner and subsequently committed suicide. Identification and determination of the afore-mentioned xenobiotics in blood samples collected from the male and female victims were performed employing high performance liquid chromatography coupled with electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS). The analytes were isolated from blood samples using the solid phase extraction (SPE) method. The blood samples collected from the male and female demonstrated respectively 110 and 196 ng/mL of AMB-FUBINACA O-desmethyl acid metabolite, 1935 and 357 ng/mL of U-47700, 250 and 200 ng/mL of N-desmethyl-U-47700, as well as 410 and 200 ng/mL of N,N-didesmethyl-U-47700. The concentration values of new psychoactive substances (NPS’s) in blood samples originating from the male and female were within the ranges encountered in cases of poisoning, including these resulting in death. Nevertheless, the evident signs of exsanguination proof that the woman was alive when she sustained lethal injuries. The presented cases illustrate the difficult to be anticipated effect exerted on the users by NPS’s.     

The role of social media in clubfoot: information sharing and social support

PurposeClubfoot is the most common congenital foot deformity in children. Caregivers often seek medical information on the internet. The aim of the study was to characterize how social media is used by caregivers to access medical information.MethodsA search was performed on Facebook, Twitter and YouTube platforms. Information was quantitatively assessed. Comments were qualitatively assessed, and the Kruskal-Wallis test was used to study thematic comment distribution.ResultsIn total, 58 Facebook groups and pages, 109 YouTube accounts and ten Twitter accounts related to clubfoot were discovered from 2007 to 2019. Facebook groups and pages had a collective 56 123 members and 80 544 total likes, respectively. YouTube had a collective 3 280 454 views, with 54 969 total comments throughout the accounts. Comment themes most commonly included sharing information and advice (38.7%), appreciation and success stories (12.8%), emotional support (12.7%) and social media as a second opinion (11.9%). Facebook groups contained a significantly higher number of comments related to ‘social media as a second opinion’ compared with Facebook pages (p = 0.001), Twitter (p = 0.016) and YouTube (p < 0.0001) while YouTube contained a significantly lower number of comments related to ‘sharing information’ compared with Facebook groups, pages and Twitter (p < 0.0001).ConclusionSocial media continues to be a growing tool for information sharing and the findings of this study highlight the importance placed by caregivers on the advice of their peers. The online presence of caregivers may represent an opportunity for orthopaedic surgeons to communicate with patients and help them make informed decisions.Level of evidenceIV     

Public Discourse Against Masks in the COVID-19 Era: Infodemiology Study of Twitter Data

BackgroundDespite scientific evidence supporting the importance of wearing masks to curtail the spread of COVID-19, wearing masks has stirred up a significant debate particularly on social media.ObjectiveThis study aimed to investigate the topics associated with the public discourse against wearing masks in the United States. We also studied the relationship between the anti-mask discourse on social media and the number of new COVID-19 cases.MethodsWe collected a total of 51,170 English tweets between January 1, 2020, and October 27, 2020, by searching for hashtags against wearing masks. We used machine learning techniques to analyze the data collected. We investigated the relationship between the volume of tweets against mask-wearing and the daily volume of new COVID-19 cases using a Pearson correlation analysis between the two-time series.ResultsThe results and analysis showed that social media could help identify important insights related to wearing masks. The results of topic mining identified 10 categories or themes of user concerns dominated by (1) constitutional rights and freedom of choice; (2) conspiracy theory, population control, and big pharma; and (3) fake news, fake numbers, and fake pandemic. Altogether, these three categories represent almost 65% of the volume of tweets against wearing masks. The relationship between the volume of tweets against wearing masks and newly reported COVID-19 cases depicted a strong correlation wherein the rise in the volume of negative tweets led the rise in the number of new cases by 9 days.ConclusionsThese findings demonstrated the potential of mining social media for understanding the public discourse about public health issues such as wearing masks during the COVID-19 pandemic. The results emphasized the relationship between the discourse on social media and the potential impact on real events such as changing the course of the pandemic. Policy makers are advised to proactively address public perception and work on shaping this perception through raising awareness, debunking negative sentiments, and prioritizing early policy intervention toward the most prevalent topics.
