Subjective sleep parameters: A marker to PTSD symptoms evolution? A 4-year longitudinal study

Disturbed sleep is a common feature after exposure to a traumatic event, especially when PTSD develops. However, although there is evidence suggesting a potential role of sleep disturbance in the progression of PTSD symptoms, the interrelationship between sleep and PTSD symptoms has yet to be determined. In order to address this knowledge gap, we have investigated the influence of initial sleep characteristics on the evolution of post-traumatic stress disorder (PTSD) symptoms over 4 years of follow-up among individuals exposed to the Brazilian Kiss nightclub fire. Participants were individuals exposed to the 2013 Kiss nightclub fire in Brazil. Sleep characteristics and PTSD symptoms were measured within the 4 years following the fire by self-report questionnaires, such as The Pittsburgh Sleep Quality Index (PSQI), and PTSD Checklist - Civilian version (PCL-C). Generalized estimating equations (GEE) models were used to examine the longitudinal associations (by estimating the relative effects of initial sleep problems on PTSD symptoms after adjusting for covariates). Comprehensive information concerning socio-demographic factors, health status, and sleep complaints were obtained. A total of 232 individuals were included. In GEE models, no significant interactions were observed between sociodemographic variables and PTSD symptoms in the follow-up period, however, associations were found between PTSD at baseline and the following factors: the female gender, the victim individuals and the existence of prior psychiatric disease. Initial subjective sleep parameters were strongly associated with PTSD symptoms over 4 years, mainly the presence of disturbed dreams (p = 0.012), increased sleep latency (p = 0.029), and reduced sleep duration (p = 0.012). Sleep complaints and PTSD symptoms were common among individuals after the disaster. The current study has found that the presence of sleep complaints, especially increased sleep latency, presence of disturbed dreams and short sleep duration, in the initial presentation after the fire was consistently associated with the perpetration of PTSD symptoms in the next 4 years of follow-up. These findings suggest that interventions addressing these sleep complaints have the potential to reduce the persistence and/or severity of PTSD symptoms.

Memescape Narratives of Romanian Social Movements (2013-2021): A Framing Theory Perspective

In the digital age, social movements increasingly leverage memes to shape narratives and mobilize support. This study examines Romanian social movements through the lens of memes from 2013 to 2021, focusing on the Save Roșia Montană Campaign, the Colectiv nightclub fire protests, the #REZIST movement, and anti-restriction protests. Data were collected from popular Romanian Facebook meme pages and other online platforms. Applying framing theory, we seek to determine how memes identify issues, assign blame, propose solutions, and motivate participation. Our findings reveal that Romanian memes often criticize digital activism as superficial, remix mainstream cultural images, and use satire to challenge dominant narratives. This study underscores the potential of memes to reflect and influence public discourse and sociopolitical debates in Romania.

How the Deadliest Nightclub Fire in History Improved Medical Interventions and Regulations and Impacted Legal Enforcement

Introduction:This presentation is a continuation of a WADEM presentation from 2013 entitled: Fires in Social Settings: An Examination of Prevention Strategies.Method:Nightclubs should be a place of fun and frivolity, but sometimes they become a place of death and destruction. The fire at the Cocoanut Grove in Boston Massachusetts, USA, in November, 1942 was the deadliest nightclub fire worldwide with a death toll of 492 and over 130 injured. Since that tragedy, regulations that could prevent or mitigate lethal incidents at nightclubs continue to be unenforced globally. This presentation will describe not only elements leading up to the Cocoanut Grove fire, but the resulting advances that have improved the lives and safety of the public.Results:The discussion begins by examining the general environment within the U.S. in fall of 1942. Appointed and elected officials tasked with protecting the public to reduce occurrences for such disasters failed in their performance of their respective roles. Groundbreaking medical advances used to treat the victims include the use of penicillin, methods of treating cutaneous burns, the use of electrolyte balance to aid in determining the ongoing treatment of burn victims, as well as other medical advances improved directly as a result of the fire. Additionally, the first systematic study of grief and survivors’ guilt and the recognition of what is now called Post Traumatic Stress Disorder commenced.Conclusion:Finally the divergent theories of the sources of the fires, how fire codes have changed in the aftermath as well as how the parties that were directly or indirectly responsible for the fire were disciplined by the judicial system will be reviewed.

Ensuring safe evacuation of people from nightclubs

The paper considers the problems of standardisation of evacuation routes and exits in nightclub buildings. The absence of regularities of people's movement in such buildings in the normative and research literature does not make it possible to estimate adequately the projected and existing planning decisions from the point of view of providing the safe evacuation of people, but also the value of individual fire risk. The analysis of fires has shown that the main cause of loss of life in a nightclub fire is untimely evacuation due to the accumulation of human traffic in front of the building exits. In order to determine the parameters of the flow of people, there were conducted preliminary field observations in nightclub buildings. Statistical analysis of the data obtained made it possible to establish the dependence of the movement of people up and down the stairs, horizontal path and through the doorway. The results of modeling of people evacuation have shown significant differences between the data presented in the methodology of assessment of fire risk and the data obtained in the research. The data obtained allow a reliable assessment of the criteria of safe evacuation of people in the design and operation of nightclubs, as well as the calculation of individual fire risk.

Effects of transcranial direct current stimulation (tDCS) in "Kiss nightclub fire" patients with post-traumatic stress disorder (PTSD): A phase II clinical trial.

Considered the second biggest tragedy with fatal victims caused by fire, the Kiss nightclub fire tragedy that occurred in the interior of southern Brazil brought several problems to survivors. It is reported that 30-40% of victims of disasters can develop post-traumatic stress disorder. Application of repetitive transcranial magnetic stimulation has shown promising results in the treatment of post-traumatic stress disorder. Transcranial direct current stimulation similar to repetitive transcranial magnetic stimulation, a neuromodulation technique, has shown promise in treatment of neuropsychiatric disorders. A clinical trial was conducted from March 2015 to July 2016 in "KISS nightclub fire" disaster patients diagnosed with post-traumatic stress disorder without complete remission of symptoms, over 18 years, and who maintained pharmacological treatment. Treatment was given using electrodes as cathode (right dorsolateral prefrontal cortex) and anode (contralateral deltoid muscle); a current of 2 mA was used for 25 cm² area (0.08 mA/cm² current density); 30 min once a day for 10 days continuously. Patients assessed pre- and post-intervention, 30 days' and 90 days' post-intervention. Post-Traumatic Stress Disorder Checklist, Civilian version, Montreal Cognitive Assessment, and Hamilton Depression and Anxiety Rating Scale were used. One hundred forty-five subjects were screened and eight analyzed; 87.5% were female; 30.88 ± 7.74 years were of mean age. Post-intervention results: no cognitive impairment (Montreal Cognitive Assessment), 60% reduction in Hamilton Depression Rating Scale (moderate depression turns normal) (p < 0.001), 54.39% Hamilton Anxiety Rating Scale reduction (moderate-to-severe symptoms turn into mild symptoms) (p < 0.001), and 20% Post-Traumatic Stress Disorder Checklist, Civilian version scale decrease (high severity post-traumatic stress disorder symptoms turn moderate to moderately high severity) (p < 0.001). Post-traumatic stress disorder symptoms improvement was maintained 30-days post-intervention (Post-Traumatic Stress Disorder Checklist, Civilian version, p = 0.025) and improvement in symptoms of depression (Hamilton Depression Rating Scale, p = 0.006) and anxiety (Hamilton Anxiety Rating Scale, p = 0.028) in 90 days post-intervention. Despite decrease over time, improvement in post-traumatic stress disorder, depression and anxiety symptoms was maintained throughout the first month after treatment. Transcranial direct current stimulation adjuvant can be an alternative treatment to refractory post-traumatic stress disorder, either as monotherapy or as treatment enhancement strategy. They can also be an option for patients who do not want or do not tolerate pharmacological management.

Post-traumatic stress disorder prevalence and sleep quality in fire victims and rescue workers in southern Brazil: a cross-sectional study

ObjectivesThis survey was conducted to evaluate the prevalence of post-traumatic stress disorder (PTSD) and the sleep quality in victims and rescue team of the third deadliest nightclub fire in the world. Study designA cross-sectional study. MethodsParticipants were victims and rescue workers exposed to a fire at a nightclub, which occurred in January 2013 in Southern Brazil. The Pittsburgh Sleep Quality Index (PSQI), composed of seven subjective sleep variables (including daytime dysfunction), and PTSD Checklist – Civilian version (PCL-C) were applied to all people who sought medical attention at the local reference center in the first year after the event. Comprehensive information was obtained concerning sociodemographic factors, health status, and sleep complaints. ResultsA total of 370 individuals, 190 victims and 180 rescue workers, were included. Participants were 70% male, with an average age of 29 years. The prevalence of PTSD was 31.9%, ranging from 24.4% for rescue workers to 38.9% for victims. The prevalence of poor sleep quality was 65.9%, ranging from 56.1% for rescue workers to 75.3% for victims. Most of the participants with PTSD (91.5%) had PSQI scores >5 (poor sleepers), against 54.0% of the non-PTSD individuals. All seven PSQI subscores showed significant differences between PTSD and non-PTSD individuals, especially daytime dysfunction. Sex, shift work, previous psychiatric disease, and sleep quality remained associated with PTSD in adjusted models, with a prevalence ratio (95% CI) of 1.76 (1.28–2.43) in females, 1.73 (1.17–2.55) in shift workers, 1.36 (1.03–1.80) in individuals with psychiatric disease history, and 5.42 (2.55–11.52) in poor sleepers. ConclusionsThe presence of daytime dysfunction increased by at least tenfold the prevalence of PTSD in this sample. Considering that daytime dysfunction was shown to be strongly associated with PTSD, sleep-related issues should be addressed in the assessment of individuals exposed to traumatic events, both victims and rescuers. Factors like shift work and female sex were also associated with PTSD, especially among victims.

Investigation on the causes and consequences of Kiss nightclub fire in Brazil

Nightclub fires are often catastrophic because it usually outbreak during events that have many people together in a confined place. This is what happened in the Kiss nightclub, in 2013, in Brazil. This paper presents the results of a research in the causes and consequences of this fire. Numerical simulations carried out with the Fire Dynamics Simulator (FDS) software allowed to determine the fire spread and the temperature evolution and smoke movement inside the nightclub. They have been also carried out numerical simulations with the Pathfinder software for studying the evacuation event of the nightclub in function of the fire development. These simulations have been carried out for two scenarios: (a) considering what existed in the building in the day of the fire and (b) what should exist in the building according to the current Brazilian standards. The numerical models were calibrated with data taken from reports, news and videos of the fire and results from laboratory tests especially carried out in this research. It was concluded that if proper finishing and coating materials had been used, the fire could not have broken out and spread so fast. On the other hand, if adequate emergency exits exist probably the number of victims would not have been so high. Some advices for fire safe construction of these buildings and to the fire safety regulations are given in the paper.

PrioritEvac: an Agent-Based Model (ABM) for Examining Social Factors of Building Fire Evacuation

Fire evacuation modeling benefits from the application of social science both in terms of accuracy and external validation. This paper describes PrioritEvac, a novel agent-based model which incorporates the social dimension of group loyalty into fire evacuation and responses to fire and smoke. It uses individual priorities, making for a dynamic approach that allows greater agency and nuance. PrioritEvac is programmed in NetLogo and validated using extensive data collected from the Station nightclub fire. The statistical analysis of the results of the model indicate that, compared to historical patterns, it reproduces along multiple metrics including a mean of 114 deaths (std. dev. = 38) over 50 runs, which puts the actual result of the fire within one standard deviation of the mean results of the simulation. Overall, the mean differential along all the metrics is 79, significantly outperforming all published ABM models of the Station nightclub fire that did not incorporate social relationships.

The politics of mourning in post-communist Romania: unravelling the thanatopolitics of grievable deaths

ABSTRACT National days of mourning are state-sponsored rituals of collective grief enacted in the public sphere by political authorities to symbolically mark and emotionally cope with a socially significant loss. These officially declared and ceremonially performed state rituals of communion in grief provide privileged epistemic opportunities for unravelling the politics of grievability underpinning a society’s willingness to mourn its dead. This paper focuses on comparing and contrasting two case studies – the Colectiv nightclub fire and the flu epidemics – in order to grasp the politics of national mourning in the Romanian post-communist context. After identifying the criteria of grievability underlying the declaration of national mourning in cases of mass death as consisting in a ‘chronotopic togetherness’ in death that is characterised by an ‘instantaneity of emotional shock,’ the paper argues for enlarging these criteria of grievability so as to include the victims of socially invisible traumas inflicted by structural violence, such as those killed in epidemics and car road accidents.

The role of personality in posttraumatic stress disorder, trait resilience, and quality of life in people exposed to the Kiss nightclub fire.

ObjectiveTo evaluate the relationship among personality (according to Cloninger’s psychobiological model), posttraumatic stress disorder (PTSD) symptoms, trait resilience and quality of life (QoL) in people who were exposed to the Kiss nightclub fire.Methods188 participants were assessed with the Posttraumatic Checklist–civilian version (PCL-C), the Resilience Scale (RS), the Temperament and Character Inventory (TCI), the World Health Organization Quality of Life–Bref (WHOQOL-Bref), and the WHOQOL-100 Spirituality, religiousness, and personal beliefs (WHOQOL-100-SRPB). Data were analyzed in a dimensional approach, with correlation analysis, multiple linear regression and Structural Equation Modeling (SEM), with PCL-C, RS, and WHOQOL-Bref dimensions as dependent variables.ResultsMultiple linear regression showed that PTSD symptoms were predicted by harm avoidance (β = .34, p < .001), self-directedness (β = -.28, p < .01), and self-transcendence (β = .24, p < .01). Trait resilience was predicted by harm avoidance (β = -.38, p < .01), self-directedness (β = .20, p < .05), and self-transcendence (β = .18, p < .05). Also, PTSD symptoms had considerable negative effect on all dimensions of QoL. Self-transcendence was a positive predictor of subjective and spiritual QoL. SEM showed that QoL was predicted by PTSD symptoms (β = -.52, p < .001), trait resilience (β = .30, p < .001), cooperativeness (β = .135, p = 0.40), and self-directedness (β = .27, p < .01). The effect of self-directedness on QoL was mediated by PTSD symptoms and trait resilience. PTSD symptoms also mediated the relationship between trait resilience and QoL, and RS mediated the relationship of personality and PTSD symptoms.ConclusionThe study gives insights on prediction of PTSD severity, trait resilience and QoL from temperament and character traits, in a sample of people exposed to the Kiss nightclub fire. Harm avoidance was the most influent trait on PTSD symptoms and trait resilience. Self-directedness was the most import trait related to QoL, still that it was more related to PTSD severity than personality traits. Self-transcendence had positive effects on both PTSD symptoms and trait resilience, indicating a coping style that may coexist with psychopathology.

The Role of the Humanitarian Logistics in the Kiss Nightclub Case

The aim of this paper was to conduct a descriptive study of the Kiss nightclub fire associated to a literature review in order to synthesize data regarding the logistics employed in the mass disaster management. A discussion comparing the scientific evidence and data from the Kiss nightclub case is presented. This paper focuses on the following aspects: role and importance of the media, management of donations, and coordination of the humanitarian logistics. In the case herein analyzed, the humanitarian response was considered adequate, especially in the survivors’ care. An efficient coordination strategy was adopted, and the media played a vital role requesting blood donations. Further research and case studies in the area of logistics are needed to achieve more effective responses in mass disasters.

Modelling the influence of crowd control railings on the Kiss nightclub evacuation

Fires in crowded gathering places such as nightclubs generate imminent risks to people’s lives, as supported by historical facts. Building evacuation is defined as fundamental to prevent the occurrence of a tragedy. In the Kiss nightclub fire, many people could not reach the exit because of the controlling rails positioned in front of exit doors, as pointed-out by firefighters and survivors. This study aimed to evaluate the influence of these barriers in the escaping of Kiss nightclub, using computerassisted simulation. Four simulations were run, considering two types of capacity, each one with and without the rails. As preliminary analyses, the simulations presented a reduction of nearly 50% of the total time for the nightclub evacuation without the rails, confirming the barriers as a factor that considerably increased evacuation time of the nightclub occupants.

460 Preventing Mass Casualty Fires Caused by Pyrotechnics

Since the beginning of this millennium over 900 people have lost their lives and almost 3000 have been injured in at least 10 burn mass casualty incidents that occurred as a result of the use of pyrotechnics in crowded nightclubs. The latest of these events was the Bucharest “Colectiv” nightclub fire in October 2015.. The series of events that lead to this disaster are strikingly similar to many former events. As is commonly known, prevention is much more effective than any treatment. This fact is especially true in the case of burn mass casualty events with a common preventable cause. On the night of October 30th, 2015, pyrotechnics were activated during a music concert in the “Colectiv” nightclub in Bucharest, Romania. The sparks reached the acoustic foam on one of the building’s columns which caused it to ignite and quickly burn upwards where it continued to burn the wooden ceiling and the entire nightclub. The 300–400 people estimated to be in the nightclub tried to escape through the only exit that was open, stampeding on the way. The immediate result of this fire was 26 fatalities and 184 injured victims, of which an additional 38 died within the following weeks. The same mechanism of fire, pyrotechnics being activated in nightclubs, has lead to burn mass casualty incidents in the Netherlands and Brazil in 2001, in the US in 2003 (The Station nightclub fire), in Argentina in 2004, in Ecuador and China in 2008, in Thailand and Russia in 2009, and in Taiwan in 2011. Some of these incidents were also worsened by the tendency of nightclubs to lock emergency exits, thus leaving the huge crowds with only one exit, inevitably causing a stampede. The average victim counts of these “copycat killers” are ~90 fatalities and ~300 injured per incident. It is our duty as burn care providers to act in order to prevent such incidents from happening again. Burn care providers worldwide, fire departments and local and national authorities should be made aware of this danger, and legislation should ban the use of pyrotechnics in nightclubs, and enforce safety codes including existence of open emergency exits. The power of social media can also be harnessed for educating the public as to the dangers of the use of pyrotechnics indoors. We should strive to prevent further use of pyrotechnics in nightclubs and other indoor venues by communicating this to the community and authorities in every method we can.

O corpo no espaço público: Emoções e processos reivindicatórios no contexto da “Tragédia de Santa Maria”

Resumo Este artigo tem como foco as manifestações públicas realizadas por familiares e amigos de vítimas do incêndio da Boate Kiss em Santa Maria, Rio Grande do Sul, atentando para as dimensões emocionais e corporais nelas envolvidas e para as transformações que se processaram com o passar do tempo. Apesar de perceberem o agravamento de seu sofrimento no desdobramento de suas relações com as instituições (Prefeitura, Ministério Público, Câmara dos Vereadores), muitos familiares reorganizaram suas vidas acompanhando o andamento dos processos judiciais e participando de manifestações públicas cujas bandeiras são: para que “não se repita” e para que “os responsáveis paguem pela tragédia”. Através de observação participante, acompanhamento de manifestações e de reportagens sobre a “tragédia”, a pesquisa mostra o trabalho micropolítico das emoções na transformação dos sentidos do acontecimento.

El activismo de las víctimas del incendio del club Kiss: evento traumático, causa pública y conflictos morales

Este artículo analiza el activismo de los familiares de las víctimas del incendio del club Kiss que tuvo lugar en Santa María, en el sur de Brasil, en 2013 y que causó 242 muertes. En los últiimos tres años he acompañado las acciones llevadas a cabo por el movimiento Santa Maria do Luto à Luta. En este texto centro mi atención en la relación entre este movimiento y el gobierno a través del análisis de las políticas públicas de salud y del conflicto que emergió tras el indicente entre el movimiento y el Ministerio Público, una institución de gobierno responsable de la vigilancia de los derechos individuales y difusos en la escala local. Lo que este conflicto pone en evidencia es el hecho de que la omisión del Estado incrementa la percepción del evento como traumático por parte de quiénes han sido afectados. Mi investigación entabla un diálogo con otros trabajos antropológicos que también se centran, de una u otra manera, en la relación entre movimientos de víctimas y el Estado con el fin de enfatizar la conexión entre sufrimiento, negligencia estatal y construcción de una causa. En mi propio trabajo, tomo en cuenta algunas de las formas de legitimación del discurso de las víctimas, creado por familiares en su lucha por la derogación de la afirmación de "locura" versada sobre ellos. Finalmente, me acerco a los amplios debates sobre el lugar de la víctima en el espacio público y el lenguaje del sufrimiento como una vía para posicionarse políticamente. La relación con el Estado también ofrece algunas claves sobre la producción de subjetividades de afectados por el evento del club Kiss; es a través de esa producción, precisamente, que el evento será interpretado.

A Computational Study of the Station Nightclub Fire Accounting for Social Relationships

Using agent-based modeling, this study presents the results of a computational study of social relationships among more than four hundreds evacuees in The Station Nightclub building in Rhode Island. The fire occurred on the night of February 20, 2003 and resulted in 100 fatalities. After summarizing and calibrating the computational method used, parametric studies are conducted to quantitatively investigate the influences of the presence of social relationships and familiarity of the building floor plan on the death and injury tolls. It is demonstrated that the proposed model has the ability to reasonably handle the complex social relationships and group behaviors present during egress. The simulations quantify how intimate social affiliations delay the overall egress process and show the extent by which lack of knowledge of a building floor plan limits exit choices and adversely affects the number of safe evacuations.

Response and legislative changes after the Kiss nightclub tragedy in Santa Maria/RS/Brazil: Learning from a large-scale burn disaster

PurposeA major fire occurred on January 27, 2013, at 02:30 at Kiss nightclub in the city of Santa Maria, State of Rio Grande do Sul, in Southern Brazil. In this retrospective report, we aimed to describe the nightclub fire event, its immediate consequences, and evaluated its impact on legislation. Our objective was to disseminate the lessons we learned from this large-scale nightclub fire disaster. MethodsWe conducted a literature review in PubMed and Lilacs database from 2013 to 2015 related to the nightclub Kiss, Santa Maria, fire, burns, and similar events worldwide over the past 15 years. We searched in the general press and online media information sites, and seeking legislation about this topic at the federal level in Brazil. We reported on the legislation changes that resulted from this nightclub fire. ResultsCurrent federal legislation on fire prevention and the scope of public safety, including night clubs and discos, states is the duty of the state and everyone’s responsibility, pursuant to Article 144 of the Federal Constitution of Brazil. Thus, the federal union, individual states and municipalities have the power to legislate on fire prevention, and especially to ensure the security of the population. A state law called “Law Kiss”, was passed in 2014, establishing standards on safety, prevention and protection against fire in buildings and areas of fire risk in the state of Rio Grande do Sul. On a national level, a law of prevention and fire fighting in Brazil was also drafted after the Santa Maria disaster (Law project no. 4923, 2013). Currently, this bill is still awaiting sanction before it can take effect. ConclusionAs we push for enactment of the national law of prevention and fire fighting in Brazil, we will continue emphasizing fire prevention, fire protection, fire fighting, means of escape and proper management. All similar events in this and other countries remind us that similar tragedies may occur anywhere, and that the analysis of facts, previous mistakes, during and after the incident are crucial to our understanding, and will help us lessen the chance of future occurrences.

Religion-Based User Generated Content in Online Newspapers Covering the Colectiv Nightclub Fire

&lt;p&gt;The high degree of interactivity of the Internet, combined with the almost ubiquitous presence of forums on online media publications, has offered everybody the possibility to express their opinions and beliefs on websites. This paper uses content analysis to examine the religion-based comments that were posted on 8 Romanian mainstream news websites in reply to articles regarding a fire that broke out during a rock concert in Bucharest, killing over 50 people and injuring more than 100. The analysis also included the answers to these comments. Among the findings, we have discovered that the highest percentage of religion-based comments made some type of reference to Satanism and that very few of them expressed compassion towards the victims. On the other hand, counter-speech strategies managed to halt hate speech in almost half of the cases where they were employed. However, personal attacks against religion-based commentators were the most commonly used form of counter-speech, contributing to an unfriendly climate on the forums.&lt;/p&gt;

Firefighting Tactics during a Fire Event at a Nightclub

Entertainment centers are typically equipped with flammable materials. In addition, consumers (and employees) of these establishments are relatively unfamiliar with their internal environments, escape routes, and fire safety equipment. Therefore, fire hazards often result in severe casualties and property loss. In this study, Fire Dynamics Simulator was used to simulate a severe nightclub fire recently occurred in Taiwan. Data were collected from field observations and media reports to establish a numerical model for the actual fire. Important fire dynamic parameters such as temperature distribution, smoke diffusion and carbon monoxides concentration were computed using the model. The results of this analysis can be used to formulate/analyze the firefighting and rescue tactics for similar fires, which would decrease the risk of disaster occurrence and increase rescue efficiency, thereby reducing casualties and property loss.
