Cannabis use and dependence among festival attendees: results from the French OCTOPUS survey.

BACKGROUND: Chronic use of cannabis is associated with an increased risk of psychosocial, mental and physical health impairments. Sociohealth institutions reach a very limited proportion of cannabis users in need of treatment. Using data collected from festival attendees, this study aimed to estimate the prevalence of dependent cannabis users and to characterize cannabis dependence. METHODS: We used data from the cross-sectional OCTOPUS survey carried out at 13 music events in the French department of Loire-Atlantique between July 2017 and July 2018. 383 participants aged 18 or older underwent a face-to-face interview about their basic sociodemographics, tobacco use, alcohol use and past-year substance use. Using the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) criteria, we estimated the prevalence of dependent cannabis users and characterized their dependence. RESULTS: More than two-thirds of participants reported that they had used cannabis in the past 12 months. Among 194 regular cannabis users (at least monthly), 63.4% were dependent. At least 40% of regular users reported health and/or social consequences of cannabis use. Compared to nondependent cannabis users, dependent cannabis users were more likely to be stimulant users and hallucinogen users. CONCLUSIONS: Dependent cannabis use is common among festival attendees, especially among stimulant or hallucinogen users. Festival settings may be important arenas for i) implementing efficient harm reduction measures to prevent dependence and ii) providing information on care structures and promoting the use of care to dependent users. In addition, healthcare professionals should be aware of trends in polysubstance use among dependent cannabis users.

Association between holiday and weekend admissions and mortality outcomes among patients with acute myocardial infarction receiving percutaneous coronary intervention in Taiwan.

There is a lack of studies that concurrently differentiate the effect of the holiday season from the weekend effect on mortality risk in patients with acute myocardial infarction (AMI). We evaluated the mortality risk among patients admitted with AMI who underwent percutaneous coronary intervention, using data from the Taiwan National Health Insurance Research Database. Adult AMI patients admitted during January and February between 2013 and 2020 were enrolled and classified into the holiday season (using the Chinese New Year holiday seasons as an indicator) (n = 1729), weekend (n = 4725), and weekday (n = 14,583) groups according to the first day of admission. A multivariable logistic regression model was used to assess the risk. With the weekday group or the weekend group as the reference, the holiday season group did not have increased risks of in-hospital mortality (adjusted odds ratio [aOR] 1.15; 95% confidence intervals [CI] 0.93-1.42 or aOR 1.23; 95% CI 0.96-1.56) and 7-day mortality (aOR 1.20; 95% CI 0.90-1.58 or aOR 1.24; 95% CI 0.90-1.70). Stratified and subgroup analyses showed similar trends. We conclude that holiday season-initiated admissions were not associated with higher mortality risks in AMI admission cases than weekday or weekend admissions.

["God for us!": Catholic festivals and rites in times of epidemics, Salvador-BA, Brasil, 1918-1919]. / "Valha-nos a Providência!": festas e ritos católicos em tempos epidêmicos, Salvador-BA, Brasil, 1918-1919.

This article analyzes the reactions of Catholics linked to lay associations in the city of Salvador, in the period of the Spanish flu (1918) and smallpox (1919). Newspapers were the main sources used to identify the festivals and rites, both those practiced to ask for the intercession of the saints, and those that were suspended due to the need for social isolation. In spite of both diseases being transmissible and the short interval between the two epidemics, the analysis of the sources showed different reactions from the faithful regarding the measures of protection and the search for a cure.

O artigo analisa as reações dos católicos vinculados às associações leigas na cidade do Salvador, no período da gripe espanhola (1918) e da varíola (1919). Os jornais foram as principais fontes utilizadas para a identificação das festas e dos ritos, tanto dos praticados para pedir a intercessão dos santos quanto daqueles que foram suspensos em função da necessidade de isolamento social. Apesar de ambas as doenças serem transmissíveis e do curto espaço de tempo entre as duas epidemias, a análise das fontes evidenciou diferentes reações dos fiéis quanto às medidas de proteção e busca da cura.

Quantifying the global film festival circuit: Networks, diversity, and public value creation.

Film festivals are a key component in the global film industry in terms of trendsetting, publicity, trade, and collaboration. We present an unprecedented analysis of the international film festival circuit, which has so far remained relatively understudied quantitatively, partly due to the limited availability of suitable data sets. We use large-scale data from the Cinando platform of the Cannes Film Market, widely used by industry professionals. We explicitly model festival events as a global network connected by shared films and quantify festivals as aggregates of the metadata of their showcased films. Importantly, we argue against using simple count distributions for discrete labels such as language or production country, as such categories are typically not equidistant. Rather, we propose embedding them in continuous latent vector spaces. We demonstrate how these "festival embeddings" provide insight into changes in programmed content over time, predict festival connections, and can be used to measure diversity in film festival programming across various cultural, social, and geographical variables-which all constitute an aspect of public value creation by film festivals. Our results provide a novel mapping of the film festival circuit between 2009-2021 (616 festivals, 31,989 unique films), highlighting festival types that occupy specific niches, diverse series, and those that evolve over time. We also discuss how these quantitative findings fit into media studies and research on public value creation by cultural industries. With festivals occupying a central position in the film industry, investigations into the data they generate hold opportunities for researchers to better understand industry dynamics and cultural impact, and for organizers, policymakers, and industry actors to make more informed, data-driven decisions. We hope our proposed methodological approach to festival data paves way for more comprehensive film festival studies and large-scale quantitative cultural event analytics in general.

Holiday effect on childbirth: A population-based analysis of 21,869,652 birth records, 1979-2018.

Maternity and neonatal services always have to operate 24 hours a day and 7 days a week, and require well preparedness to guarantee safe deliveries for both mothers and babies. However, the evidence of holiday effect from large-scale data is still insufficient from the obstetrics perspective. We analyzed data of over 21 million births in Japan from January 1, 1979, to December 31, 2018. We revealed that the number of births is lower on holidays, and especially among high-risk births such as low birthweight and preterm births. The frequency of high-risk birth has been increasing over the study period, and the variation by the day of week and between holiday and non-holiday have become more prevalent in recent years.

A systematic review of interventions that impact alcohol and other drug-related harms in licensed entertainment settings and outdoor music festivals.

BACKGROUND: Harms associated with the use of alcohol and other drugs (AOD) in licensed entertainment settings (LES) and outdoor music festivals (OMF) are ongoing public health and criminal justice concerns. This systematic review provides a comprehensive, synthesized report on the evidence base of interventions that impact harm in these settings, and how they affect health, behavioral, and criminal justice outcomes. METHODS: Nine databases were searched for experimental and observational studies published between 2010 and 2021. Studies were included if they were peer-reviewed, published in English, described interventions which could impact AOD-related harms in LES or OMF (and were delivered in these environments), and reported on health, criminal justice and/or behavioral outcomes. Methodological quality was assessed using the Effective Public Health Practice Project's Quality Assessment Tool for Quantitative Studies and the Critical Appraisal Skills Program for qualitative studies. A narrative synthesis was conducted to synthesize outcomes across studies. The review protocol was registered in PROSPERO (CRD42020140004). RESULTS: Of the 48,303 studies screened, 100 met the inclusion criteria. 86 focused solely on reducing alcohol-related harm, 7 on reducing illicit drug-related harm, and 7 on both. Most (n = 88) focused on LES and evaluated changes in laws and regulations (n = 28) and/or multicomponent interventions/policies (n = 41). Multicomponent interventions showed the best results for both health (62% positive) and criminal justice (84% positive) outcomes, with 71% of studies being rated as strong quality. There was also good evidence to support the careful application of trading hour restrictions and limited but promising evidence to support medical services and drug checking. CONCLUSION: The breadth, quality and volume of evidence regarding what works in reducing AOD-related harm in recreational settings have increased in the past decade, particularly regarding LES. Findings support onsite medical services (reducing ambulance transfer rates), multicomponent interventions targeting alcohol accessibility and availability (reducing assaults), and drug checking services, but suggest other interventions such as drug detection dogs may exacerbate harm. Further, higher quality research is required to address identified gaps in the evidence base, particularly on optimal interventions within OMF, around illicit drugs more broadly and in the Global South.

Ocular Firework Injuries among Patients Presented to the Emergency Department During Festival Season in a Tertiary Eye Hospital.

Introduction: Fireworks can cause severe ocular injuries which can be prevented if used with proper precautions. It causes not only mechanical injuries but also thermal and chemical injuries. This study aimed to find out the prevalence of ocular firework injuries among patients presented to the emergency department during festival season in a tertiary eye hospital. Methods: This is a descriptive cross-sectional study done among patients presenting in the emergency department of a tertiary eye hospital after obtaining ethical approval from the Institutional Review Committee. Data of patients from medical records between 26 October 2021 to 28 November 2021 and 15 October 2022 to 17 November 2022 was collected. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 132 patients, the prevalence of ocular firework injuries was seen in 73 (55.30%) (46.82-63.78, 95% Confidence Interval). Closed globe injury was mostly observed in 56 (76.71%) patients with ocular injuries. The most common age group affected was those less than 30 years old 54 (73.97%). Conclusions: The prevalence of ocular firework injuries was found to be lower than other studies done in similar settings. Protective measures should be used to prevent ocular injuries. A public awareness program needs to be launched before such festivals. Keywords: festivals; injuries; prevalence.

Characterising differences between self-reported and wastewater-identified drug use at two consecutive years of an Australian music festival.

BACKGROUND: In the context of drug prohibition, potential adulteration and variable purity pose additional health risks for people who use drugs, with these risks often compounded by the outdoor music festival environment. Ahead of the imminent implementation of drug checking services in Queensland, Australia, this study aims to characterise this problem using triangulated survey and wastewater data to understand self-reported and detected drug use among attendees of a multi-day Queensland-based music festival in 2021 and 2022. METHODS: We administered an in-situ survey focusing on drug use at the festival to two convenience samples of 136 and 140 festival attendees in 2021 and 2022 respectively. We compared survey findings to wastewater collected concurrently from the festival's site-specific wastewater treatment plant, which was analysed using Liquid Chromatography Tandem Mass Spectrometry. RESULTS: Most survey respondents (82 % in 2021, 92 % in 2022) reported using or intending to use an illicit drug at the festival. Some respondents reported potentially risky drug use practices such as using drugs found on the ground (2 % in 2021, 4 % in 2022). Substances detected in wastewater but not surveys include MDEA, mephedrone, methylone, 3-MMC, alpha-D2PV, etizolam, eutylone, and N,N-dimethylpentylone. CONCLUSION: Many substances detected in wastewater but not self-reported in surveys likely represent substitutions or adulterants. These findings highlight the benefits of drug checking services to prevent harms from adulterants and provide education on safer drug use practices. These findings also provide useful information on socio-demographic characteristics and drug use patterns of potential users of Queensland's future drug checking service.

Effect of Christmas Holidays on Type 1 Diabetes Mellitus in Users of Glucose Flash Systems.

OBJECTIVE: Christmas holidays can impact weight and glycemic control in type 2 diabetes, but their effect on type 1 diabetes (T1D) remains understudied. This study assessed how Christmas holidays affect individuals with T1D who use flash continuous glucose monitoring systems. METHODS: This retrospective study involved 812 adults diagnosed with T1D recruited from 3 hospitals. Clinical, anthropometric, and socioeconomic data were collected. Glucose metrics from 14 days before January 1st, and before December 1st and February 1st as control periods, were recorded. Analyses adjusted for multiple variables were conducted to assess the holiday season's impact on glycemic control. RESULTS: The average time in range during the holidays (60.0 ± 17.2%) was lower compared to December (61.9 ± 17.2%, P < .001) and February (61.7 ± 17.7%, P < .001). Time above range (TAR > 180 mg/dL) was higher during Christmas (35.8 ± 18.2%) compared to December (34.1 ± 18.3%, P < .001) and February (34.2 ± 18.4%, P < .001). Differences were also observed in TAR >250 mg/dL, coefficient of variation, and average glucose (P < .05). No differences were found in time below range or other metrics. Linear regression models showed that the holidays reduced time in range by 1.9% (ß = -1.92, P = .005) and increased TAR >180 mg/dL by 1.8% (ß = 1.75, P = .016). CONCLUSION: Christmas holidays are associated with a mild and reversible deterioration in glucose metrics among individuals with T1D using flash continuous glucose monitoring, irrespective of additional influencing factors. These discoveries can be useful to advise individuals with diabetes during the festive season and to recognize potential biases within studies conducted during this timeframe.

The Diwali festival: short-term high effect of fireworks emissions on particulates and their associated empirically calculated health risk assessment at Bhubaneswar city.

This article elucidates the role of the short-term combustion of firecrackers and sparklers as a significant source of atmospheric pollutants that deteriorate ambient air quality and increase health risks during the popular Diwali festival. The study was conducted at Bhubaneswar during the festive celebration in early November 2021 (4th Nov) and late October 2022 (24th Oct) to assess the level of particulates (PM2.5 and PM10 mass concentration) and the relative health risks associated with them. PM2.5 (113.83 µg/m3) and PM10 (204.32 µg/m3) showed significant rises on D-day at all seven different sites that exceeded the NAAQS in 2021. From 2021 to 2022, an overall decrease in PM2.5 (41%) and PM10 (36%) was observed. On D-day, the total concentration of quantified metals in PM2.5 and PM10 were found to be 4.83 µg/m3 5.97 µg/m3 (2021) and 5.08 µg/m3 5.18 µg/m3 (2022) respectively. The AQI during both years (2021-2022) was found to be high for PM2.5 (unhealthy) and PM10 (moderate), but it was markedly good for all other pollutants on the scale. The overall population in the study area were under a significant health risk was observed in the overall population as PM surpassed the threshold concentration amid the festivities for consecutive years, with PM2.5 being more potent than PM10. The total excess health risk in 2022 was found to be decreased lower by ~ 88% from 2021 on D-day. But, metal exposure (through inhalation) in children were more compared to the adults for both the years. However, the exposure risk of both children and adults were high in the year 2022 with inhalation of metals like K, Al, Ba, Fe and Ca found in higher concentration and directly emitted from the firecrackers.

Assessment of ambient air quality in relation to the burning of firecrackers during the festival of Diwali: A case study of Jodhpur City (India).

The study attempts to examine the impact of firework activities during Diwali Festival on ambient air quality of Jodhpur city. Air quality parameters particulate matter of diameter 10 µm (PM10), particulate matter of diameter 2.5 µm (PM2.5), sulfur dioxide (SO2), nitrogen dioxide (NO2) and heavy metals in PM2.5 like Pb, Ni, Ba, Al, As and Sr are monitored at two locations, for 15 days, starting from 7 days before the festival of Diwali, on the day of the festival (Diwali) and 7 days after Diwali. On the occasion of Diwali, it was discovered that the 24-h average levels of various pollutants were significantly elevated compared to regular days preceding the festival. Specifically, at the HBO site, the concentrations were notably increased, with sulfur dioxide (SO2) reaching 5.62 times higher, nitrogen dioxide (NO2) at 3 times higher, particulate matter of diameter 10 µm (PM10) at 2.35 times higher, and particulate matter of diameter 2.5 µm (PM2.5) at 1.01 times higher than the usual levels before Diwali. Similarly, at the PTMM site, there were substantial elevations in pollutant concentrations during Diwali compared to pre-festival days, with SO2 registering 2.53 times higher, NO2 at 2.37 times higher, PM2.5 at 1.9 times higher, and PM10 at 1.57 times higher levels than normal. Concentration of Al, Ba, Sr and Pb at HBO site and Al at PTMM site was highest on Diwali day. Air quality index which was in good category on normal days before Diwali, fell into poor category starting from the day before Diwali and remain in poor category on normal days after Diwali. The result indicates the worsening of ambient air quality during Diwali which can adversely impact the human health in terms of various respiratory complications.

Changes in bird assemblages following an outdoor music festival: A BACI (before-after-control-impact) monitoring from central Italy.

An assessment of the short-term effects of an outdoor music festival (Jova Beach Party event; July 2019; central Italy) on bird assemblages has been carried out, adopting a BACI (Before-After-Control-Impact) survey design, and using the point counts method both in the impact site (Impact, I; where the concert was held) and in comparable Control site (C). In the I site, data have been stratified both for urban (U) and agro-mosaic (M) habitats. When comparing before and after the music event, in IU site, the species richness and the Hill diversity index decreased, differently from CU where species richness a species abundance increased. Diversity profiles highlighted the impoverishment of bird assemblages after the event, but only in the Impact urban habitats. After the musical event, individual rarefaction curves for richness were lower in IU after the concert, while, differently in CU curves are higher. These data suggest an impact in bird assemblages limited to the urban site, due to the stress mainly induced by high intensity noise pollution. Musical events may disrupt the structure of synanthropic bird assemblages, inducing a dispersal of individuals towards the surrounding landscape. Starling (Sturnus vulgaris) appeared a particularly sensitive bird. However, further efforts are necessary to study the effects of these events at species level.

Characterizing Gun Violence by Time, Day of the Week, Holidays, and Month in 6 US Cities, 2015-2021.

Developing interventions to prevent firearm-related violence and to address its consequences requires an improved understanding of when these violent events are most likely to occur. We explored gunshot events in 6 of the most populated cities in the United States by time of day, day of week, holiday/non-holiday, and month using publicly available datasets. In some of these cities, gunshot events occurred most often at nighttime, on holidays and weekends, and during summer months, with significant interaction effects. There were also time-related changes in characteristics of the victims. Primary prevention efforts aimed at curbing firearm-related violence should consider these differential risks.

Evaluation of social knowledge on photoprotection and its relationship with education and age in a Polish seaside town during summer holidays.

OBJECTIVE: This survey aimed to evaluate knowledge of photoprotection among individuals from a random group in a resort town in Poland, Kolobrzeg, and explore the correlation between their knowledge and demographics like age, gender, education, and residence. METHODS: An anonymous survey was conducted among a diverse group. This population comprised individuals from various backgrounds: health spa patients undergoing treatments, therapies and medical appointments, guests visiting the resort for leisure, passersby, and staff working at the spa and recreational facilities. The survey was designed by authors, encompassed 16 questions about knowledge on photoprotection, sunscreen use and related topics, and gathered demographic data. Responses from 142 individuals were statistically analyzed using PQStat Software. RESULTS: Only 7.7% use sunscreen all year-round. The majority apply sun protection factor (SPF) creams on sunny days or with prolonged sun exposure. Over half of the respondents (53.5%) are aware when to apply sunscreen but 43% reapply it less than every 4 h. 25.4% do not reapply at all. 38.7% think protection provided by higher SPF means longer sun exposure time. Over 50% believe SPF 30 offers double the protection of SPF 15. Almost half (46.8%) use extra sun protection, like sunglasses or hats. Significant correlations exist between education/age and certain survey responses. CONCLUSIONS: The findings emphasize the urgency to improve photoprotection knowledge in the Polish population, particularly regarding the year-round harmful solar effects and the correct use of sun protection products.

Forging gender and racial solidarities at trans-inclusive women's festivals.

This article explores the interweaving of successes and failures at trans-inclusive women's festivals. I analyze conflicts that occurred at the Mystical Womxn's Magic Festival and the Ohio Lesbian Festival. In the process, I demonstrate that working across racial and gender divides in these spaces is possible but only if we understand that solidarity is processual and relational but also, quite simply, hard work. This labor requires acknowledging that failures are an integral part of the praxis of forging alliances. By failures, I am primarily referring to moments of insensitivity, casual macroaggressions, lack of deep listening, and other common occurrences of harm. Ultimately, I argue that solidarity is a journey not an end point and that a crucial aspect of the journey is grappling with collective and personal failures along the way.

Local Firework Restrictions and Ocular Trauma.

Importance: Fireworks can cause vision-threatening injuries, but the association of local legislation with the mitigation of these injuries is unclear. Objective: To evaluate the odds of firework-related ocular trauma among residents of areas where fireworks are permitted vs banned. Design, Setting, and Participants: This case-control study was conducted at a level 1 trauma center in Seattle, Washington, among 230 patients presenting with ocular trauma in the 2 weeks surrounding the Independence Day holiday, spanning June 28 to July 11, over an 8-year period (2016-2022). Exposures: Firework ban status of patient residence. Main Outcomes and Measures: Odds of firework-related injuries among residents of areas where fireworks are legal vs where they are banned, calculated as odds ratios (ORs) and 95% CIs. Results: Of 230 consultations for ocular trauma during the study period, 94 patients (mean [SD] age, 25 [14] years; 86 male patients [92%]) sustained firework-related injuries, and 136 (mean [SD] age, 43 [23] years; 104 male patients [77%]) sustained non-firework-related injuries. The odds of firework-related ocular trauma were higher among those living in an area where fireworks were legal compared with those living in an area where fireworks were banned (OR, 2.0 [95% CI, 1.2-3.5]; P = .01). In addition, the odds of firework injuries were higher for patients younger than 18 years (OR, 3.1 [95% CI, 1.7-5.8]; P < .001) and for male patients (OR, 3.3 [95% CI, 1.5-7.1]; P = .004). Firework injuries were more likely to be vision threatening (54 of 94 [57%]) compared with non-firework-related injuries (54 of 136 [40%]; OR, 2.1 [95% CI, 1.2-3.5]; P = .01). Conclusions and Relevance: This case-control study suggests that the odds of firework-related ocular trauma were slightly higher among residents of areas where fireworks were legal compared with residents of areas where fireworks were banned. Although these results suggest that local firework bans may be associated with a small reduction in the odds of firework-related ocular trauma, additional studies are warranted to assess what actions might lead to greater reductions.
