Review
Drowning is responsible for considerable morbidity and mortality worldwide, and it is estimated that 90% of drownings are preventable. Drowning is defined as "the process of experiencing respiratory impairment from submersion/immersion in liquid." Emergency providers should focus on airway management and rapid delivery of oxygen to interrupt the drowning process and improve patient outcomes. Patients with minimal or no symptoms do not require any specific diagnostic workup, aside from physical examination and 4 to 6 hours of observation prior to discharge. Patients with more severe symptoms may present with rales and foamy secretions, and should be managed with high-concentration oxygen and positive airway pressure.

OBJECTIVE
We investigated the temporal trends and examined age-, period-, and cohort-specific effects of injury-related deaths among residents in Jiangsu to provide evidence for future injury prevention.
METHODS
This study included 406,936 injury deaths from the Jiangsu provincial population death registration system. The average annual percent change (AAPC) in age-standardized mortality rates (ASMRs) was analyzed using joinpoint regression. Age-period-cohort models were generated to explore the effects of age, period, and birth cohort effects on mortality risk.
RESULTS
ASMRs for all injuries (AAPC = -2.3%), road traffic accidents (AAPC = -5.3%), suicide (AAPC = -3.8%), and drowning (AAPC = -3.9%) showed a downward trend during 2012-2021(all < 0.05), while unintentional falls showed an upward trend (AAPC = 5.1%, < 0.05). From 2012 to 2021, the age-standardized mortality rates (ASMRs) for four primary types of injuries consistently exhibited higher among males compared to females, with rural regions displaying higher ASMRs than urban areas. Trends in ASMRs for road traffic accidents, drowning, and unintentional falls by sex and urban/rural areas were consistent with overall trends. Significant age, cohort, and period effects were identified in the trends of injury-related deaths for both sexes in Jiangsu. The age effect showed that the highest age effect for injury-related deaths was for the ages of 85 years and above, except for suicide, which was for the ages 80-84 years. Between 2012 and 2021, the period effect on road traffic accidents declined, while that on accidental falls increased. Initially, the period effect on suicide decreased but then rose, peaking in 2012 with a Relative Risk (RR) of 1.11 (95% : 1.04-1.19). Similarly, the period effect on drowning initially declined before rising, with the highest effect observed in 2013, at an RR of 1.12 (95% : 1.07-1.19). The highest cohort effects for road traffic accidents were observed in the 1957-1961 group, for accidental falls in the 1952-1956 group, and for both drowning and suicide in the 1927-1931 group.
CONCLUSION
The mortality rate of unintentional falls has been increasing. Older adults are at high risk for the four leading injuries. The improvements in mortality rates can be attributed to advancements in education, urbanization, and the promulgation and implementation of laws and policies.

"Ethical Responsibility Very Often Gets Drowned Out": A Qualitative Interview Study of Genome Scientists' and ELSI Scholars' Perspectives on the Role and Relevance of ELSI Expertise.
BACKGROUND
Genome scientists and Ethical, Legal, and Social Implications of genetics (ELSI) scholars commonly inhabit distinct research cultures - utilizing different research methods, asking different research questions, and valuing different types of knowledge. Collaborations between these two communities are frequently called for to enhance the ethical conduct of genomics research. Yet, little has been done to qualitatively compare genome scientists' and ELSI scholars' perspectives on collaborations with each other and the factors that may affect these collaborations.
METHODS
20 semi-structured interviews with US-based genome scientists and ELSI scholars were conducted between June-September 2021. Interviews were analyzed using inductive thematic analysis.
RESULTS
Genome scientists and ELSI scholars provided different understandings of the value and goals of their collaborations with each other. Genome scientists largely perceived ELSI expertise to be relevant for human subjects research; they described ELSI scholars as communicators who help the public and/or study participants better understand genomics research. In comparison, ELSI scholars viewed themselves as developing and implementing policies; they expressed frustration at how scientists can misunderstand their research methods or negatively perceive them. A combination of factors - both structural (e.g., criteria for promotion) and cultural (e.g., perceptions of what colleagues value and respect) - seemed to shape these diverging perspectives.
CONCLUSION
Academic institutions, funders, and researchers commonly call for collaborations between genome scientists and ELSI scholars, but under-consider how their different conceptual frameworks, research methods, goals, norms, and values, conjoin to affect such partnerships. Acknowledging, exploring, and addressing the complex interplay between these factors could help to more effectively facilitate collaborations between genome scientists and ELSI scholars.

Drowning is the process of respiratory impairment from immersion or submersion in a liquid. Worldwide, approximately 360,000 deaths annually can be attributed to drowning. Morbidity and mortality are a result of hypoxia, so the focus during resuscitation should be on airway management and optimizing oxygenation. This article describes several drowning scenarios and discusses appropriate response and treatment algorithms.

UNLABELLED
Lifeguards are the first responders to any type of aquatic incident, including rapid rescue situations such as boating and sporting accidents, animal bites/attacks, and cases involving massive bleeding. In their line of work, rescue boats such as Rescue Water Craft (RWC) are commonly utilized the aim of this study is to evaluate the time and technique of placing a tourniquet on the sled of an RWC navigating at full speed.
METHODS
A randomized crossover study design was used with a sample of 44 lifeguards. The inclusion criteria required that participants be certified lifeguards with experience in RWC operations and possess knowledge of responding to massive bleeding. Two CAT tourniquet placement tests were performed. In the 1) Beach-Tourniquet (B-TQ) test: it was performed on land and in the 2) Rescue Water Craft-tourniquet (RWC-TQ) test, sailing at a cruising speed of 20 knots. The evaluation was recorded in a checklist on the steps and timing of the correct application TQ by direct observation by an expert instructor.
RESULTS
The tourniquet placement on RWC was an average of 11 s slower than when placed on the beach (BT-TQ 35.7 ± 8.0 vs. 46.1 ± 10.9 s, p > 0.001). In the percentage analysis of the results on correct execution of the skills, higher values are obtained for the B-TQ test than in RWC-TQ in Distance to the wound (into 5-7 cm), band adjustment, checking the radial pulse and reporting the time of tourniquet placement (p > 0.005).
CONCLUSION
The placement of a tourniquet on a RWC navigating at 20 knots is feasible, relatively quick, and technically well executed.

Observational Study
OBJECTIVE
Data on drownings tend to underestimate mortality from this cause. The objective of this study was to describe fatal drownings recorded in Catalonia between 2019 and 2022 through forensic sources, present their characteristics, and assess the utility of this information for monitoring drowning mortality.
METHODS
A retrospective observational study based on the register of judicial deaths from the Institute of Legal Medicine and Forensic Sciences of Catalonia was carried out. Data on medicolegal aetiology, aquatic environment, age, gender, date of death, and municipality of origin were analysed. Statistical analysis was based on the comparison of proportions test based on Chi-square for categorical variables and the Mann Whitney U test for the comparison of numerical variables.
RESULTS
A total of 310 drownings were recorded, with a mean age of 57.2 years and a male predominance (77.1%). The majority of drownings were unintentional (71.3%), followed by suicides (15.5%), and cases of undetermined intent (12.6%). Compared to intentional drownings, unintentional and undetermined intent drownings had a higher percentage of males than females (81.2% vs. 56%, p<0.001), and fewer cases with Spanish nationality than foreign or undetermined nationality (60% vs. 92%, p<0.001). Middle-aged and older individuals accounted for the majority of deaths, but among unintentional drownings, those recorded in pools included significantly higher percentages of children and adolescents aged zero-fourteen years than those occurring in natural waters.
CONCLUSIONS
The results highlight the importance of drowning mortality in Catalonia and the need to strengthen preventive activities, especially for children and during episodes of intense heat. Medicolegal sources are useful for monitoring drowning mortality, but it would be beneficial if they incorporated information on variables such as place of residence and nationality.

INTRODUCTION
No published evidence was identified regarding the use of oxygen in the treatment of drowning in two recent systematic reviews. The aim of our study was to investigate the impact of on scene, pre-Emergency Medical Services (EMS) oxygen therapy by lifeguards in the resuscitation of drowning victims.
METHOD
We conducted a retrospective case match analysis of drowning patients presenting to the EDs of Sunshine Coast Hospital and Health Service. Patients were matched for age, sex and severity of drowning injury. The primary outcome was in-hospital mortality. Secondary outcomes included positive pressure ventilation (PPV) by EMS and the ED, as well as admission to the Intensive Care Unit.
RESULTS
There were 108 patients in each group. Median (IQR) age was 22 (15-43) in the oxygen group and 23 (15-44) years in the non-oxygen group. There were 45 females in the oxygen group and 41 females in the non-oxygen group. Sixteen patients had suffered cardiac arrest and three patients respiratory arrest in each group. There were five deaths in each group. Initial oxygen saturation on arrival of EMS was identical in both groups 89.2% (±19.9) in the oxygen group versus 89.3% (±21.1) (P = 0.294) in the non-oxygen group. The oxygen group required PPV more frequently with EMS (19 vs 11, P < 0.01) and in the ED (19 vs 15, P < 0.01).
CONCLUSION
On scene treatment with oxygen by lifeguards did not improve oxygenation or outcomes in drowning patients.

Studying essential genes required for dynamic processes in live mice is challenging as genetic perturbations are irreversible and limited by slow protein depletion kinetics. The first-generation auxin-inducible-degron (AID) system is a powerful tool for analyzing inducible protein loss in cultured cells. However, auxin administration is toxic to mice, preventing its long-term use in animals. Here, we use an optimized second-generation AID system to achieve the conditional and reversible loss of the essential centrosomal protein CEP192 in live mice. We show that the auxin derivative 5-Ph-IAA is well tolerated over two weeks and drives near-complete CEP192-mAID degradation in less than one hour . Prolonged CEP192 loss led to cell division failure and cell death in proliferative tissues. Thus, the second-generation AID system is well suited for rapid and/or sustained protein depletion in live mice, offering a valuable new tool for interrogating protein function .
