The South East Asian region has the world's second highest fatal drowning burden. This study reports analysis of survey data from representatives from nations within the Association of South East Asian Nations regarding current efforts, challenges and future opportunities for drowning prevention. Twenty-two responses were received from respondents from all ASEAN nations excepting Cambodia and Myanmar. Drowning prevention initiatives varied across ASEAN nations, with most efforts focused on public education and raising awareness, including the provision of drowning data to the media. The lack of comprehensive, national level data collection was identified as a challenge, necessitating strengthened data collection capacity. Governmental involvement spanned one to six different ministries, highlighting the multi-sectoral nature of drowning prevention. However, a lead ministry could be identified in only two countries. Despite the challenges identified, there remain many opportunities to strengthen drowning prevention across ASEAN nations, addressing a significant regional public health threat.

BACKGROUND
Future warming is projected to increase the heat-related mortality burden, especially for vulnerable populations. However, most previous studies focused on non-accidental morbidity or mortality, with far less research on heat-related accidental events.
METHODS
We collected individual accidental death records among all residents in Chinese mainland from June to August during 2013-2019. Accidental deaths were further divided into several subtypes by different causes. We used an individual-level, time-stratified, case-crossover study design to estimate the association between daily mean temperature and accidental deaths, and estimate its variation in seven geo-climatic zones, age (5-64, 65-74, ≥75), and sex (male, female). We then estimated the temperature-related excess accidental deaths under global warming scenarios of 1.5, 2, and 3℃.
FINDINGS
A total of 711,929 accidental death records were included in our study. We found that higher temperatures were associated with increased risks of deaths from the total accidental events and four main subtypes, including traffic, falls, drowning, and unintentional injuries. We also found that younger individuals (ages 5-64) and males faced a higher risk of heat-related mortality due to total accidents, traffic incidents, and drowning. For future climate scenarios, even under the 1.5℃ climate change scenario, 6,939 (95% eCI (empirical Confidence Interval): 6,818-7,067) excess accidental deaths per year are attributed to higher summertime daily temperature over mainland China, and the number of accidental deaths would increase by 16.71% and 33.59% under the 2℃ and 3℃ climate change scenarios, respectively. For residents living in southern coastal and northwest inland regions, the projected increase in accidental death is higher.
CONCLUSIONS
This nationwide study confirms that higher summer temperatures are linked to an increased risk of accidental deaths. Younger age groups and males face a higher risk. This indicates that current estimates of the health effects of climate change might be underestimated, particularly for younger populations.

BACKGROUND
Drowning is a major cause of death in Uganda, especially among young adults with water-based occupations and livelihoods. Information about drowning and other water-related deaths and injuries is limited. To address this gap in knowledge, study partners assessed knowledge, attitudes and beliefs about drowning and drowning prevention interventions in the Mayuge district of eastern Uganda.
METHODS
This study consisted of a mixed-methods, cross-sectional community health assessment. Research was conducted in 10 landing sites of 6 subcounties within Mayuge district bordering Lake Victoria and focused on 505 head-of-household interviews, 15 key informant interviews, 10 landing site observations and 3 focus group discussions with 10 young adults each.
RESULTS
While landing site observations revealed high lake use, households reported limited community drowning prevention knowledge and revealed risky behaviours and attitudes towards water safety. Less than one-third (30.9%) of participants reported that at least one family member can swim. 64.2% of all respondents reported no existing safety measures (eg, signage, fences) around the lake and 95.8% reported no aquatic emergency response system in their community. The majority of households (85.7%) had experienced a drowning incident in their area. Key informants and focus group participants were eager for community-based interventions and offered solutions that reflected international drowning prevention recommendations.
CONCLUSIONS
The results reveal gaps in services, access and knowledge and highlight a need for water safety services and interventions in lakeside communities in Uganda and throughout the Lake Victoria Basin.

INTRODUCTION
Drowning is defined as the process of experiencing respiratory impairment from submersion or immersion in liquid. It is the third leading cause of unintentional injury-related deaths worldwide, accounting for 7% of all injury-related deaths.1 Our group sought to improve resident education regarding the basics of water safety and rescues as an event developed by our wilderness medicine (WM) interest group. With the growing number of WM Fellowships, specialty tracks, interest clubs and the regular inclusion of WM topics in residency didactics, exposure to WM topics has increased greatly.2 There is a large overlap between wilderness medicine and the field of emergency medicine. Both require stabilization, improvisation, and the treatment of environmental/exposure illnesses. It is imperative that emergency medicine physicians understand the complex pathophysiology of drowning, as well as recognize and manage potential associated traumatic injuries including fractures and critical hemorrhage. Our goal is to provide additional curricular instruction on prehospital management of water-related emergencies and related injuries to emergency medicine residents.
EDUCATIONAL OBJECTIVES
By the end of the session, the learner will be able to: 1) describe the pathophysiology of drowning and shallow water drowning, 2) prevent water emergencies by listing water preparations and precautions to take prior to engaging in activities in and around water, 3) recognize a person at risk of drowning and determine the next best course of action, 4) demonstrate three different methods for in-water c-spine stabilization in the case of a possible cervical injury, 5) evaluate and treat a patient after submersion injury, 6) appropriately place a tourniquet for hemorrhage control, and 7) apply a splint to immobilize skeletal injury.
EDUCATIONAL METHODS
A group of 16 resident learners received a thirty-minute introduction discussion (with open discussion) regarding water safety, basic water rescue methods, and submersion injury pathophysiology. They then progressed through three stations designed to emphasize select skills and knowledge related to submersion injury management, water rescue, and tourniquet and splint placement.
RESEARCH METHODS
Participants completed a six-item questionnaire after the event designed to help gage participant comfort level of treatment, management, and experience regarding water safety, drowning, and related traumatic emergencies. Each item was ranked from 0 for "strongly disagree" to 10 for "strongly agree." Total mean scores before and after were compared.
RESULTS
Sixteen individuals participated in the sessions and survey. The total mean score for the six-item analysis increased following the workshop (26.3 before versus 46.9 after, p = 0.001). The positive improvement in all categories indicated increased comfort in the topics of the small group sessions, with the largest improvement in the question about comfort in effectively evaluating and treating a patient presenting to the ED after a submersion injury.
DISCUSSION
Utilizing discussions and hands-on group sessions increased residents' perceived learning. This model can be applied to an extensive number of wilderness medicine topics for learners of all levels. For individuals with time-restrictive schedules, this model is an efficient mode of learning and teaching drowning and injury management skills with the potential for further topics and future courses.
TOPICS
Wilderness medicine, water safety, pathophysiology of drowning, in-water rescues, in-water cervical spine stabilization, management of drowning in the ED, splinting, tourniquets.

INTRODUCTION
The burden of drowning is gaining prominence on the global agenda. Two United Nations system resolutions in 3 years reflect rising political support, but priorities remain undefined, and the issue lacks a global strategy. We aimed to identify strategic priorities for advancing global drowning prevention using a modified Delphi method.
METHODS
An advisory group was formed, and participants recruited with diverse expertise and backgrounds. We used document review, and data extracted from global health partnerships to identify strategic domains and draft priorities for global drowning prevention. Participants rated the priorities in two Delphi rounds, guided by relevance, feasibility and impact on equity, and where consensus was ≥70% of participants rating the priority as critical.
RESULTS
We recruited 134 participants from research (40.2%), policy (26.9%), technical (25.4%) and community (7.5%) backgrounds, with 38.1% representing low- and middle-income countries. We drafted 75 priorities. Following two Delphi rounds, 50 priorities were selected across the seven domains of research and further contextualisation, best practice guidance, capacity building, engagement with other health and sustainable development agendas, high-level political advocacy, multisectoral action and strengthening inclusive global governance. Participants scored priorities based on relevance (43.2%), feasibility (29.4%) and impact on equity (27.4%).
CONCLUSION
Our study identifies global priorities for drowning prevention and provides evidence for advocacy of drowning prevention in all pertinent policies, and in all relevant agendas. The priorities can be applied by funders to guide investment, by researchers to frame study questions, by policymakers to contrast views of expert groups and by national coalitions to anchor national drowning prevention plans. We identify agendas including disaster risk reduction, sustainable development, child and adolescent health, and climate resilience, where drowning prevention might offer co-benefits. Finally, our findings offer a strategic blueprint as the field looks to accelerate action, and develop a global strategy for drowning prevention.

BACKGROUND
Expanding support for drowning prevention is evidenced by interlinked Resolutions at the United Nations (2021) and World Health Assembly (2023). While progress has accelerated, a universally agreed definition for drowning prevention remains absent. Here, we aim to develop a conceptual definition of drowning prevention using the Delphi method.
METHODS
First, we conducted a document review to guide our development and consensus-building process. Then, we formed an advisory group and recruited participants with diverse expertise to contribute to Delphi-method surveys. In the first round, participants selected from draft concepts to build a definition and delineate between the terms drowning prevention and water safety. In the second round, we presented a codeveloped definition, and three statements based on first-round findings. We then sought participant feedback where ≥70% support was considered consensus-based agreement.
RESULTS
Participants (n=134) were drawn from community (7.46%), policy (26.87%), research (40.30%) and technical backgrounds (25.37%), and low-income and middle-income countries (38.06%). In the first- round, half (50.74%) disagreed with the proposition that drowning prevention was synonymous to water safety, while 40.30% agreed. The second- round achieved consensus-based agreement (97.27%) for the definition: Drowning prevention is defined as a multidisciplinary approach that reduces drowning risk and builds resilience by implementing evidence-informed measures that address hazards, exposures and vulnerabilities to protect an individual, community or population against fatal and non-fatal drowning.
CONCLUSION
The Delphi method enabled the codevelopment of our conceptual definition for drowning prevention. Agreement on the definition forms the basis for strengthened multisectoral action, and partnerships with health and sustainable development agendas. Defining drowning prevention in terms of vulnerability and exposure might increase focus on social determinants and other upstream factors critical to prevention efforts.

Drowning is the leading cause of death by accident of everyday life in people under 25 years of age. Xenobiotics are frequently involved in drowning cases but their influence on the diagnosis of fatal drowning has not been studied so far. This preliminary study aimed to assess the influence of an alcohol and/or a drug intoxication on the autopsy signs of drowning, and on the results of diatom analyses in drowning deaths. Twenty-eight autopsy cases of drowning including 19 freshwater drownings, 6 seawater drownings, and 3 brackish water drownings were prospectively included. Toxicological and diatom tests were performed in each case. The influence of alcohol and other xenobiotics on drowning signs and diatom analyses was assessed separately then in combination through a global toxicological participation score (GTPS). Diatom analyses showed positive results in lung tissue in every case. No significant association was found between the degree of intoxication and the diatom concentration in the organs, even after considering freshwater drowning cases only. The vast majority of the traditional autopsy signs of drowning were not significantly affected by the individual toxicological status either, with the exception of lung weight which tended to raise in case of intoxication, probably due to the pulmonary edema and congestion increase. Further research on larger autopsy samples is needed to confirm the results of this exploratory study.

Diagnosing the drowning site is a major challenge in forensic practice, particularly when corpses are recovered from flowing rivers. Recently, forensic experts have focused on aquatic microorganisms, including bacteria, which can enter the bloodstream during drowning and may proliferate in corpses. The emergence of 16S ribosomal RNA gene (16S rDNA) amplicon sequencing has provided a new method for analyzing bacterial composition and has facilitated the development of forensic microbiology. We propose that 16S rDNA amplicon sequencing could be a useful tool for inferring drowning sites. Our study found significant differences in bacterial composition in different regions of the Guangzhou section of the Pearl River, which led to differences in bacteria of drowned rabbit lungs at different drowning sites. Using the genus level of bacteria in the lung tissue of drowned rabbits, we constructed a random forest model that accurately predicted the drowning site in a test set with 100% accuracy. Furthermore, we discovered that bacterial species endemic to the water were not always present in the corresponding drowned lung tissue. Our findings demonstrate the potential of a random forest model based on bacterial genus and composition in drowned lung tissues for inferring drowning sites.

OBJECTIVES
The Risk Information System for Commercial Fishing (RISC Fishing) merged information on fishermen and vessel incident types from various databases. This descriptive study examined linked fisherman injury records (fatal and nonfatal) and vessel incident records in Oregon and Washington from 2000 to 2018 in the RISC Fishing database. The circumstances of incidents and any association with fishermen outcomes were explored to identify injury prevention opportunities.
METHODS
The statistical analyses included a descriptive study of incidents related to the injury characteristics and frequency of outcomes by incident type. Further analyses included contingency tables and Pearson Chi-Square tests for selected variables to determine if there were associations between vessel incident outcomes (fatality, nonfatal injury, no injury).
RESULTS
A total of 375 reported incidents with 93 cases of fatalities, 239 nonfatal injuries, and over 6,575 fishermen with no injury were described. Of fatalities, 90% were due to drowning, with only 2% of victims reported donning survival equipment. Deckhands experienced fatal and nonfatal injuries most frequently. The most common factors associated with nonfatal injuries included contact with objects (event), walking on vessel and hauling gear (work activities), and fractures and open wounds (nature). The most common final event leading to a vessel disaster with no injury being reported was sinking (76%). Distributions between the incident outcomes (fatality, nonfatal injury, and no injury) differed by vessel activity/type, fishery/gear, and event leading to the incident.
CONCLUSION
Linked information of fishermen injury outcomes and vessel incident information showed that events and settings that involve fatalities are qualitatively different from incidents resulting in only nonfatal injuries or uninjured survivors. Vessel-level approaches for mitigating fatalities, such as ensuring vessel stability, improving navigation/operation decisions, and spotlighting survival equipment policies/rescue priorities could have a significant impact. Work task-specific prevention strategies for nonfatal injuries related to the larger vessels (catcher/processors and processors) and smaller vessels (with pot/trap gears) are paramount. The use of linked information provided in reports can provide a fuller incident picture to advance efforts to improve the working conditions of commercial fishermen.

INTRODUCTION
Although previous research has examined the risk factors for drowning behavior among adolescents, it is unclear whether this association is influenced by water safety knowledge. This study aimed to examine whether water safety knowledge is associated with adolescents' drowning risk behaviors and whether drowning risk perceptions and attitudes could have a chain mediating role in the association between water safety knowledge and adolescents' drowning risk behaviors.
METHODS
This study included 7,485 adolescents from five Chinese provinces and cities. We used the Drowning Risk Behaviors Scales (DRBS) to evaluate the risk of drowning behaviors. The Water Safety Knowledge Scale (WSKS) was used to evaluate the competence level of water safety knowledge. The Drowning Risk Perceptions Scale (DRPS) was used to evaluate the risk level of perceptions, and the Drowning Risk Attitudes Scale (DRAS) was used to evaluate the risk level of attitudes.
RESULTS
The results of the mediating effect test showed that water safety knowledge (WSK) affected drowning risk behaviors (DRB) through three indirect paths. Drowning risk perceptions (DRP) and attitudes (DRA) have significantly mediated the association between WSK and DRB. In conclusion, DRP and DRA can act as mediators between WSK and DRB, not only individually, but also as chain mediators, where the direct effect is-0.301, the total indirect effect is-0.214, and the total mediated indirect effect is 41.5%.
DISCUSSION
Water safety knowledge negatively predicts adolescents' drowning risk behaviors; water safety knowledge has an inhibitory effect on drowning risk perceptions. Water safety knowledge can directly influence adolescents' drowning risk perceptions and indirectly affect drowning risk behaviors through the mediation of drowning risk perceptions and attitudes comprising three paths: (1) the drowning risk perceptions mediation path, (2) the drowning risk attitudes mediation path, and (3) the drowning risk perceptions and attitudes mediation paths.
