Diet culture on TikTok: a descriptive content analysis.

OBJECTIVE: To investigate how dieting is portrayed on TikTok and the potential implications for public health considering the effect of diet culture on eating disorders amongst young people. DESIGN: A cross-sectional descriptive content analysis of 250 videos from the five most popular diet-related hashtags. A codebook was developed to analyse the content of the videos and collect the engagement for each video (likes, comments and shares). SETTING: TikTok website. PARTICIPANTS: There were no participants in this study. RESULTS: More than half of the videos portrayed 'body checking', a potentially harmful practice for body image. Of the videos that represented body image, almost half represented body image negatively. However, most videos promoted the idea of 'healthy eating', and only 6·4 % displayed disordered eating behaviours. Over half of the videos provided dietary advice, and of those videos, most content creators claimed to be experts (64 %). Claiming expertise was not significantly associated with engagement; however, the use of humour was significantly associated with engagement. Additionally, males were more likely than females to disclose their goals of the diet. CONCLUSIONS: Overall, it appears that TikTok is commonly used to share nutrition tips and personal experiences around dieting and eating in general, often employing humour as an effective technique. The popularity of the platform and rapid dissemination of information would be a useful tool for health professionals, especially those working with eating disorders, to utilise.

'Black Out Rage Gallon' (aka borg): An investigation of a risky drinking trend on TikTok.

ISSUE ADDRESSED: A 'Black Out Rage Gallon' (borg) is a customised, individual alcoholic beverage popularised on TikTok, whereby half the water in a gallon jug is replaced with alcohol (usually spirits), flavourings, electrolytes and caffeine. We investigated the characteristics and portrayal of the emerging alcohol trend associated with the hashtag descriptor #borg on TikTok. METHODS: We identified highly viewed TikTok videos with the #borg hashtag (n = 103) and conducted a content analysis, capturing viewer engagement ('likes', shares, comments), techniques used, characteristics of featured individuals, and the portrayal of alcohol and risky drinking behaviours. RESULTS: Alcohol was visible in three quarters of the videos analysed (n = 78, average amount of alcohol present 865 mL per borg) and consumed in one third of the videos (n = 34). One quarter of videos (n = 25) promoted alleged benefits of borg consumption compared to other alcohol products or approaches to drinking, yet only nine videos included a warning about potential harms. CONCLUSIONS: The borg trend on TikTok may encourage risky drinking, by portraying it in a style that younger viewers are likely to see as fun and entertaining. SO WHAT?: We were able to gain a better understanding of how this potentially health harming activity is represented on a social media platform that is popular with young people. The speedy dissemination of this trend highlights the need to monitor, investigate and counter emerging trends. Concurrently, there is an urgent need for content restrictions to limit the visibility and promotion of risky alcohol consumption on TikTok.

Where are the alcohol advertising hotspots near schools?

ISSUE ADDRESSED: Physically locating liquor stores near schools can strongly influence the chances of youth accessing and consuming alcohol, and may also increase children's exposure to alcohol advertising. Investigating the association between the presence of a liquor store near a school and the prevalence of outdoor alcohol advertising is crucial from a policy perspective, as it can inform future regulations on the placement of liquor stores and outdoor advertising near educational institutions. METHODS: All outdoor alcohol advertising within a 500 m radius (audit zone) of 64 randomly selected schools from local government areas across metropolitan Perth was identified by direct observation; recording the size, setting, location and content of each advertisement. Results were compared based on whether the school audit zone contained a liquor store or not. RESULTS: Over half (n = 36, 56%) of all school audit zones had at least one alcohol advertisement, with an average number of 5.9 alcohol advertisements per zone (SD = 10.2). The majority (97.9%) of advertisements were in the 38 audit zones containing a liquor store (average = 9.7, SD = 11.9 per zone), compared to zones without a liquor store (average = .3, SD = .7 per zone). CONCLUSIONS: Perth school zones containing a liquor store in their 500 m radius had, on average, 30 times more outdoor alcohol advertising, compared with school zones without a nearby liquor store. SO WHAT?: The siting of liquor stores and the display of alcohol advertisements around educational settings require combined policy, planning and public health approaches to mitigate children's exposure to alcohol marketing, especially during school transit.

The queers are all right: a content analysis of LGBTQIA + mental health on TikTok.

The formation of online communities instils a sense of connectedness which can ameliorate the mental health concerns that result from minority stressors for lesbian, gay, queer, intersex, asexual, and other diverse genders/sexualities (LGBTQIA+). The aim of this study was to explore how LGBTQIA + people communicate social and mental health concerns on TikTok. It was anticipated that factors affecting mental health, such as minority stressors and community connectedness, would be addressed by the videos collected. Engagement statistics, demographics and content analysis were used to describe the 50 most-viewed videos across the top five related hashtags: #genderidentity, #lgbtqawareness, #sexualidentity, #lgbtmentalhealth, and #transmentalhealth. The content analysis indicates that TikTok is used as a way for members of the LGBTQIA + community to connect with each other and enhance feelings of community connectedness, which research shows may buffer the effects of minority stressors. Engagement with social media can be especially beneficial for those who may not be able to connect in the real-world. Further interactions, such as analysis of the comment section, should be investigated to develop a fuller understanding of how LGBTQIA + TikTok users respond to these contents.

Parents' concerns about Leavers celebrations: A cross-sectional study.

ISSUE ADDRESSED: "Schoolies' or "Leavers' is a mass celebration of the end of compulsory schooling where excessive drinking is considered integral to the experience. Leavers are at risk of alcohol-related harms. This paper reports the concerns of parents for their Year 12 students (age 17 years) when attending Leavers celebrations. METHODS: Parents of Year 12 students (n = 87) were asked to complete a survey in relation to their eldest school-aged child. Six items relating to parents' level of "concern' about Leavers celebrations were measured on a 5-point scale. RESULTS: Parents were concerned about their child experiencing peer pressure to consume alcohol (60%), 30% were neutral or unconcerned about peer pressure. Almost two thirds of parents were concerned about their child being injured as a result of their own alcohol use (66.7%). Parental concern relating to their child being injured because of others' alcohol use rated most highly (88.5%). CONCLUSIONS: Findings suggested that parents were more concerned with harm caused to their child by others than the use of alcohol by their own child. Parents were somewhat less concerned with peer pressure to drink, though given peer influence is a major factor in young people's decisions regarding alcohol, parents' apparent confidence in their children's capacity to resist peer pressure may be inflated. SO WHAT?: Future interventions reinforcing the important role that parents play in the decisions that young people make while at Leavers have the potential to reduce their alcohol intake and subsequent alcohol-related harm.

Fat talk: Influences on body image in childcare.

ISSUE ADDRESSED: This research explored the use of "fat talk" by early childhood educators and their awareness of their potential influence on the developing body image of young children. METHODS: Mixed methods comprising focus groups, telephone interviews and demographic surveys with 44 early childhood educators Australia-wide. RESULTS: Findings showed many educators in this research recognised that they had a role to play in the development of children's body image, though some were unsure when body image began to develop. Educators engaged widely in "fat talk," in the vicinity of children or other educators, and accepted such talk as normal. DISCUSSION: "Fat talk" features in the workplace and is commonly used by early childhood educators. Its influence on the development of body image on young children did not appear to be well understood by early years' educators or of a concern to them. CONCLUSIONS: Since body image develops in children from around three years of age, the role of early childhood educators in its development should not be overlooked. SO WHAT? RELEVANCE TO HEALTH PROMOTION: Body image is a misunderstood public health concern, with long-term impacts on weight, mental health and physical health. Promotion of positive body image and the early recognition of body image disturbance are crucial, as children who exhibit body dissatisfaction in their formative years have a greater risk of severe body image disturbance as they progress through childhood and adolescence. Since early childhood educators spend significant time with children, encouraging them to avoid engaging in "fat talk" and instead to promote positive body image is warranted.

Three novel Pseudomonas phages isolated from composting provide insights into the evolution and diversity of tailed phages.

BACKGROUND: Among viruses, bacteriophages are a group of special interest due to their capacity of infecting bacteria that are important for biotechnology and human health. Composting is a microbial-driven process in which complex organic matter is converted into humus-like substances. In thermophilic composting, the degradation activity is carried out primarily by bacteria and little is known about the presence and role of bacteriophages in this process. RESULTS: Using Pseudomonas aeruginosa as host, we isolated three new phages from a composting operation at the Sao Paulo Zoo Park (Brazil). One of the isolated phages is similar to Pseudomonas phage Ab18 and belongs to the Siphoviridae YuA-like viral genus. The other two isolated phages are similar to each other and present genomes sharing low similarity with phage genomes in public databases; we therefore hypothesize that they belong to a new genus in the Podoviridae family. Detailed genomic descriptions and comparisons of the three phages are presented, as well as two new clusters of phage genomes in the Viral Orthologous Clusters database of large DNA viruses. We found sequences encoding homing endonucleases that disrupt a putative ribonucleotide reductase gene and an RNA polymerase subunit 2 gene in two of the phages. These findings provide insights about the evolution of two-subunits RNA polymerases and the possible role of homing endonucleases in this process. Infection tests on 30 different strains of bacteria reveal a narrow host range for the three phages, restricted to P. aeruginosa PA14 and three other P. aeruginosa clinical isolates. Biofilm dissolution assays suggest that these phages could be promising antimicrobial agents against P. aeruginosa PA14 infections. Analyses on composting metagenomic and metatranscriptomic data indicate association between abundance variations in both phage and host populations in the environment. CONCLUSION: The results about the newly discovered and described phages contribute to the understanding of tailed bacteriophage diversity, evolution, and role in the complex composting environment.

Awake and Alert: Examining the Portrayal of Energy Drinks on TikTok.

PURPOSE: Energy drinks (EDs) are not recommended for minors' consumption due to a myriad of health risks, but marketing initiatives persist. This study explored the promotion of EDs on TikTok, a platform frequented by children and adolescents. METHODS: 197 highly viewed videos from the four top ED-related hashtags on TikTok were coded for engagement variables, user information, sponsorship status, video content, and sentiment toward EDs. RESULTS: Of the 197 videos analyzed (combined 70 + million views), 29% disclosed sponsorship and 22% featured a child/adolescent. ED consumption appeared in 46% of videos, with 15% depicting hazardous consumption. Most videos (67%) had a positive sentiment toward EDs. DISCUSSION: ED-related TikTok videos are positively framed, have high engagement, and are not restricted for viewing by minors. As the platform's underage user-base grows, such videos may encourage heightened consumption. Given the known health risks, effective age-gated content restrictions are needed to reduce minors' exposure.

Acceptability of OP/Na swabbing for SARS-CoV-2: a prospective observational cohort surveillance study in Western Australian schools.

OBJECTIVES: When the COVID-19 pandemic was declared, Governments responded with lockdown and isolation measures to combat viral spread, including the closure of many schools. More than a year later, widespread screening for SARS-CoV-2 is critical to allow schools and other institutions to remain open. Here, we describe the acceptability of a minimally invasive COVID-19 screening protocol trialled by the Western Australian Government to mitigate the risks of and boost public confidence in schools remaining open. To minimise discomfort, and optimise recruitment and tolerability in unaccompanied children, a combined throat and nasal (OP/Na) swab was chosen over the nasopharyngeal swab commonly used, despite slightly reduced test performance. DESIGN, SETTING AND PARTICIPANTS: Trialling of OP/Na swabbing took place as part of a prospective observational cohort surveillance study in 79 schools across Western Australia. Swabs were collected from 5903 asymptomatic students and 1036 asymptomatic staff in 40 schools monthly between June and September 2020. OUTCOME MEASURES: PCR testing was performed with a two-step diagnostic and independent confirmatory PCR for any diagnostic PCR positives. Concurrent surveys, collected online through the REDCap platform, evaluated participant experiences of in-school swabbing. RESULTS: 13 988 swabs were collected from students and staff. There were zero positive test results for SARS-CoV-2, including no false positives. Participants reported high acceptability: 71% of students reported no or minimal discomfort and most were willing to be reswabbed (4% refusal rate). CONCLUSIONS: OP/Na swabbing is acceptable and repeatable in schoolchildren as young as 4 years old and may combat noncompliance rates by significantly increasing the acceptability of testing. This kind of minimally-invasive testing will be key to the success of ongoing, voluntary mass screening as society adjusts to a new 'normal' in the face of COVID-19.

Pivot and Persist: A Technical Report on Adapting an Existing Multi-Institutional Bootcamp to a Hybrid Platform.

The coronavirus disease 2019 (COVID-19) pandemic has disrupted most in-person simulation training, including established simulation-based medical bootcamps. These sessions are important for the preparation of new trainees to think critically about common clinical scenarios, practice technical skills, and optimize leadership, teamwork, and communication. Having the opportunity to hone these skills in a safe environment is instrumental for the development of trainees' confidence and professional identity formation, and may contribute to patient safety. When the annual New England/Mid-Atlantic regional first-year neonatology fellows' bootcamp was jeopardized by COVID restrictions, we implemented a novel approach to adapt the existing in-person format and curriculum for large-scale hybrid delivery. The resultant two-day session was well-received by both participants and facilitators. Important lessons from this experience, including adaptions to the curriculum, schedule, simulation interface and hybrid platform, are relevant to educators seeking to conduct large-scale virtual simulation-based educational sessions.

DETECT Schools Study Protocol: A Prospective Observational Cohort Surveillance Study Investigating the Impact of COVID-19 in Western Australian Schools.

Introduction: Amidst the evolving COVID-19 pandemic, understanding the transmission dynamics of the SARS-CoV-2 virus is key to providing peace of mind for the community and informing policy-making decisions. While available data suggest that school-aged children are not significant spreaders of SARS-CoV-2, the possibility of transmission in schools remains an ongoing concern, especially among an aging teaching workforce. Even in low-prevalence settings, communities must balance the potential risk of transmission with the need for students' ongoing education. Through the roll out of high-throughput school-based SARS-CoV-2 testing, enhanced follow-up for individuals exposed to COVID-19 and wellbeing surveys, this study investigates the dynamics of SARS-CoV-2 transmission and the current psychosocial wellbeing impacts of the pandemic in school communities. Methods: The DETECT Schools Study is a prospective observational cohort surveillance study in 79 schools across Western Australia (WA), Australia. To investigate the incidence, transmission and impact of SARS-CoV-2 in schools, the study comprises three "modules": Module 1) Spot-testing in schools to screen for asymptomatic SARS-CoV-2; Module 2) Enhanced surveillance of close contacts following the identification of any COVID-19 case to determine the secondary attack rate of SARS-CoV-2 in a school setting; and Module 3) Survey monitoring of school staff, students and their parents to assess psycho-social wellbeing following the first wave of the COVID-19 pandemic in WA. Clinical Trial Registration: Trial registration number: ACTRN12620000922976.

Sharing is Caring: A Study of Food-Sharing Practices in Australian Early Childhood Education and Care Services.

Food connects people, and can significantly impact the physical, social and emotional development of young children. Food sharing and family-style mealtimes can support healthy eating practices and psychological well-being among young children, and carersother than family members, such as Early Childhood Education and Care staff, play an important role in the provision of these practices. Despite increasing numbers of Australian children attending Early Childhood Education and Care services, there is often reluctance among staff to promote such mealtime practices, to the detriment of children's social and emotional development. The aim of this paper was to focus on the potential role of Early Childhood Education and Care services in facilitating food sharing and family-style mealtime practices in the earliest stages of the lifespan. A qualitative, netnographic approach was used, and data was collected as part of the broader 'Supporting Nutrition for Australian Childcare' (SNAC) study, via online conversation threads, observations and qualitative interviews. Findings demonstrated that whilst many Early Childhood Education and Care services are committed to supporting food sharing and family-style mealtime practices, a number of barriers were reported. These included the perception that babies and toddlers could not participate in these practices, concerns about food hygiene and cross contamination of allergens, and negative parental influences on food sharing. In conclusion, this paper supports the practice of food sharing in Early Childhood Education and Care settings and calls for them to become embedded in everyday operations to support the physical, social and emotional development of Australia's future generations.

Whole and/or in bits: Bohm, Matte Blanco, and (un)consciousness.

Psychoanalysis can be conceptualized as a process of shifting unconscious knowing into consciously graspable forms. Theoretical physicist and author David Bohm considers the order of the individual psyche and links it to the order of the universe, conceptualizing both as an unbroken and unified system. Matte Blanco focuses on the unfolding function of the symmetrical position, and Kristeva highlights the poetic language of psychoanalysis, drawing us closer to the flow of experience of the indivisible symmetrical mode. Thus, the aim of the psychoanalytic enterprise is not merely to "understand" unconscious contents in conscious forms, but to promote symbolic processes which lead to discovery and creativity, and which allow greater access to the unconscious or indivisible mode.

Passion, Desire, Perversion: Love and Death in Psychoanalysis.

This paper contrasts full passion with what I am calling empty passion. As examples of full passion, Melanie Klein's lovehate, Kristeva's maternal passion, Zizek's political passion, and the passion of friendship are discussed in relation to empty passion, a narcissistic desire to fill a lack or a hole at the center of being. This empty passion is related to the Lacanian demand to serve or to become the desire of the Other and to André Green's concept of the psychic dilemma of the Dead Mother. Clinical and literary examples of empty passion are provided as illustrations.

Microbial community structure and dynamics in thermophilic composting viewed through metagenomics and metatranscriptomics.

Composting is a promising source of new organisms and thermostable enzymes that may be helpful in environmental management and industrial processes. Here we present results of metagenomic- and metatranscriptomic-based analyses of a large composting operation in the São Paulo Zoo Park. This composting exhibits a sustained thermophilic profile (50 °C to 75 °C), which seems to preclude fungal activity. The main novelty of our study is the combination of time-series sampling with shotgun DNA, 16S rRNA gene amplicon, and metatranscriptome high-throughput sequencing, enabling an unprecedented detailed view of microbial community structure, dynamics, and function in this ecosystem. The time-series data showed that the turning procedure has a strong impact on the compost microbiota, restoring to a certain extent the population profile seen at the beginning of the process; and that lignocellulosic biomass deconstruction occurs synergistically and sequentially, with hemicellulose being degraded preferentially to cellulose and lignin. Moreover, our sequencing data allowed near-complete genome reconstruction of five bacterial species previously found in biomass-degrading environments and of a novel biodegrading bacterial species, likely a new genus in the order Bacillales. The data and analyses provided are a rich source for additional investigations of thermophilic composting microbiology.
