Meta-Analysis
INTRODUCTION
Breath-hold (BH) diving has known risks, for example drowning, pulmonary oedema of immersion and barotrauma. There is also the risk of decompression illness (DCI) from decompression sickness (DCS) and/or arterial gas embolism (AGE). The first report on DCS in repetitive freediving was published in 1958 and from then there have been multiple case reports and a few studies but no prior systematic review or meta-analysis.
METHODS
We undertook a systematic literature review to identify articles available from PubMed and Google Scholar concerning breath-hold diving and DCI up to August 2021.
RESULTS
The present study identified 17 articles (14 case reports, three experimental studies) covering 44 incidences of DCI following BH diving.
CONCLUSIONS
This review found that the literature supports both DCS and AGE as potential mechanisms for DCI in BH divers; both should be considered a risk for this cohort of divers, just as for those breathing compressed gas while underwater.

BACKGROUND
Noncommunicable diseases (NCDs) and mental health conditions represent a growing proportion of disease burden in low- and middle-income countries (LMICs). While past efforts have identified interventions to be delivered across health system levels to address this burden, the challenge remains of how to deliver heterogenous interventions in resource-constrained settings. One possible solution is the Integration of interventions within existing care delivery models. This study reviews and summarizes published literature on models of integrated NCD and mental health care in LMICs.
METHODS
We searched Pubmed, African Index Medicus and reference lists to conduct a scoping review of studies describing an integrated model of NCD or neuropsychiatric conditions (NPs) implemented in a LMIC. Conditions of interest were grouped into common and severe NCDs and NPs. We identified domains of interest and types of service integration, conducting a narrative synthesis of study types. Studies were screened and characteristics were extracted for all relevant studies. Results are reported using PRISMA-ScR.
RESULTS
Our search yielded 5004 studies, we included 219 models of integration from 188 studies. Most studies were conducted in middle-income countries, with the majority in sub-Saharan Africa. Health services were offered across all health system levels, with most models implemented at health centers. Common NCDs (including type 2 diabetes and hypertension) were most frequently addressed by these models, followed by common NPs (including depression and anxiety). Conditions and/or services were often integrated into existing primary healthcare, HIV, maternal and child health programs. Services provided for conditions of interest varied and frequency of these services differed across health system levels. Many models demonstrated decentralization of services to lower health system levels, and task shifting to lower cadre providers.
CONCLUSIONS
While integrated service design is a promising method to achieve ambitious global goals, little is known about what works, when, and why. This review characterizing care integration programs is an initial step toward developing a structured study of care integration.

Review
Adult drowning is a complex and multifactorial public health challenge requiring community, national and global efforts to mitigate impacts. This study updates the evidence base for public health interventions that address adult fatal and non-fatal drowning. A systematic review was undertaken of the peer-reviewed literature for English-language primary studies published between 2011 and 2021describing a drowning intervention with adults. Twenty-two studies were included. Most studies (n = 16) were conducted in high-income countries. Yearly trends in drowning prevention intervention publications were analysed with 2015 (n = 6) the peak publishing year. Over half of the study designs were pre-post (n = 15). Intervention duration ranged from 4 hours to 11 years. Ten studies described either behaviour change theory or formative evaluation to inform design. Thirteen studies targeted interventions at a population level, seven at a group level and two at individual level. Studies identified a range of prevention strategies, categorised as behavioural (n = 9) (e.g., swimming lessons), socio-ecological (n = 8) (e.g., mandatory personal flotation devices) and mixed (n = 5) (e.g., awareness campaign and barriers to prevent access to water). A range of outcomes were described including changes in awareness, water safety knowledge, attitudes, water safety behaviours and skills, environmental, policy and regulation changes and drowning rates. Findings indicate a small but important increase in the evaluation and publication of effective interventions to prevent adult drowning. The complexity of the issues surrounding drowning requires multi-strategy and context -specific adult focused prevention interventions. Contemporary evidence that identifies effective interventions that contribute to prevention efforts is an essential first step in addressing the challenge.

Review
BACKGROUND
Drowning is a complex health issue, where global agendas call for greater emphasis on multisectoral action, and engagement with sectors not yet involved in prevention efforts. Here, we explored the conceptual boundaries of drowning prevention in peer-review and grey literature, by reviewing the contexts, interventions, terminologies, concepts, planning models, and sector involvement, to identify opportunities for multisectoral action.
METHODS
We applied scoping review method and have reported against Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension for Scoping Reviews checklist. We searched four electronic databases for peer-reviewed articles published on 1 January 2005 and 31 December 2020 and five databases for grey literature published on 1 January 2014 and 31 December 2020. We applied the search term "drowning," and charted data addressing our research questions.
RESULTS
We included 737 peer-reviewed articles and 68 grey documents. Peer-publications reported situational assessments (n=478, 64.86%) and intervention research (n=259, 35.14%). Drowning was reported in the context of injury (n=157, 21.30%), commonly in childhood injury (n=72, 9.77%), mortality studies (n=60, 8.14%) and in grey documents addressing adolescent, child, environmental, occupational and urban health, refugee and migrant safety and disaster. Intervention research was mapped to World Health Organization recommended actions. The leading sectors in interventions were health, leisure, education and emergency services.
CONCLUSION
Although drowning is often described as a major health issue, the sectors and stakeholders involved are multifarious. The interventions are more often initiated by non-health sectors, meaning multisectoral action is critical. Framing drowning prevention to reinforce cobenefits for other health and development agendas could strengthen multisectoral action. Greater investment in partnerships with non-health sectors, encouraging joint planning and implementation, and creating systems for increased accountability should be a priority in future years.

INTRODUCTION
Globally, drowning is a significant cause of preventable mortality and morbidity. The Eastern Mediterranean region (EMR) comprises 22 countries of extreme disparity in income and is a region impacted by conflict and migration. We systematically review literature published on drowning in the EMR.
METHODS
Peer-reviewed literature (limited to original research) was identified using Embase, PubMed, Scopus, SportsDiscus, and Web of Science databases. Literature was independently dual screened at title/abstract and full text stages with dual data extraction (20% of included studies). Studies were included if they reported epidemiology, risk/protective factors and/or prevention strategies for drowning (unintentional and intentional; fatal and non-fatal) of residents, tourists or migrants in the EMR. Literature was assessed against the [Australian] National Health and Medical Research Council's Levels of Evidence.
RESULTS
Seventy-two studies were included in this review (epidemiology 68 studies; risk/protective factor 13 studies; prevention strategies 19 studies). Iran (n = 27), Saudia Arabia (n = 11) and Pakistan (n = 10) recorded the largest number of dedicated studies. Studies predominately focused on unintentional drowning. Ninety-two percent of included studies (n = 66) were ranked as being low evidence (level IV). The majority of studies explored drowning among children and adolescents (0-19 years). All-age fatal drowning rates varied from a low of 0.48 per 100,000 (United Arab Emirates; 2002; Ministry of Health death registry data) to a high of 18.5 per 100,000 (Egypt; 2014-15; WHO mortality database). Commonly identified risk factors included being male, young age, submersion time and resident status. Common prevention strategies public education, lifeguard supervision, and cardiopulmonary resuscitation.
DISCUSSION
Gaps in understanding of drowning burden in some countries within the region, as well as region-wide risk factor identification for adult drowning, intentional and migration-related drowning, impair the ability of nations to advance drowning prevention. There is a need for investment in implementation and evaluation of drowning prevention interventions in the EMR.
CONCLUSION
Drowning is a significant cause of mortality and morbidity in the EMR. The recent UN declaration on global drowning prevention may provide the impetus to invest in drowning prevention research, policy, and advocacy with the aim of reducing drowning-related harms in the EMR.

Review
Medical conditions can increase drowning risk. No prior study has systematically reviewed the published evidence globally regarding medical conditions and drowning risk for adults. MEDLINE (Ovid), PubMed, EMBASE, Scopus, PsycINFO (ProQuest) and SPORTDiscus databases were searched for original research published between 1 January 2005 and 31 October 2021 that reported adult (≥15 years) fatal or non-fatal drowning of all intents and pre-existing medical conditions. Conditions were grouped into the relevant International Classifications of Diseases (ICD) codes. Eighty-three studies were included (85.5% high-income countries; 38.6% East Asia and Pacific region; 75.9% evidence level III-3). Diseases of the nervous system (n = 32 studies; 38.6%), mental and behavioural conditions (n = 31; 37.3%) and diseases of the circulatory system (n = 25; 30.1%) were the most common categories of conditions. Epilepsy was found to increase the relative risk of drowning by 3.8 to 82 times, with suggested preventive approaches regarding supervised bathing or showering. Drowning is a common suicide method for those with schizophrenia, psychotic disorders and dementia. Review findings indicate people with pre-existing medical conditions drown, yet relatively few studies have documented the risk. There is a need for further population-level research to more accurately quantify drowning risk for pre-existing medical conditions in adults, as well as implementing and evaluating population-level attributable risk and prevention strategies.

BACKGROUND
Annual global travel reached an all-time high of 1.4 billion international tourist visits in 2019. It is estimated that injury accounts for close to 25% of deaths in travellers, most of which are theoretically preventable. However, there are limited data available on injury occurrence and outcomes in travellers. Our objective was to better understand the relative risk of dying from injury that arises from the novel environments and behavioural changes associated with foreign travel.
METHODS
A systematic literature review was conducted (PubMed, Embase and Scopus) according to PRISMA guidelines that included studies published in English since 1990 that reported injury deaths in tourists per 100 000-person years or as a proportion of total tourist deaths in comparison to a non-traveller population. We also included studies that reported data allowing calculation of these rates. Relative rates or proportions of overall injury mortality, mortality due to traffic accidents, drowning and homicide were summarized.
RESULTS
In total, 1847 articles were identified, 105 underwent full-text review, and 10 articles were suitable for data extraction. There was great variability of relative risk reported, but overall, travellers appear to have a higher risk of injury mortality than domestic populations, with relative rates of injury death ranging from 1.04 to 16.7 and proportionate mortality ratios ranging from 1.43 to 3.
CONCLUSIONS
Tourists should be aware of the increased risk of dying from road traffic hazards, drowning and homicide while traveling abroad. Specific geographies and activities associated with higher risk should be emphasized. Travel medicine practitioners and organizations that send people abroad should counsel travellers regarding these risks and seek ways to reduce them, including encouraging potential risk-mitigating behaviours. There is a need to improve systems of data collection and reporting on injury deaths in travellers and to study the impact of pre-travel and institutional interventions aimed at reducing this risk.

Review
Children between the ages of 4-6 years represent the population most affected by drowning accidents, while their early involvement in physical activity, and more specifically in aquatic activities is a key factor in their future physical life journey. The systematic review's purpose was to identify aspects in the intervention's studies with children and/or their parents that had a significant impact on the Aquatic Literacy (AL) dimensions mentioned as motor, psychological, affective, and cognitive. The PICO method was used to define the research question and PRISMA checklist searched for articles in nine databases: Cochrane, Embase, ERIC, ProQuest, PsychInfo, PubMed, Scopus, SportDiscus, and Web of Science. Eligibility criteria were: (1) English language, (2) primary research, (3) population of 4-6 year old children or their parents, (4) intervention study design, and (5) results related to at least one of the AL domains. The strength of evidence and the risk of bias were assessed. Results showed relatively poor number of studies for such a vulnerable population regarding the drowning risk ( = 8 for parents and = 14 for children intervention). Studies did not show a consensus on which educational approach was more beneficial than others. Concerning parental education, results were rather homogeneous, especially concerning the theoretical frameworks employed and the relevancy to include parents in swimming programs. The development of pedagogical tools for promotion and evaluation, based on the AL theoretical framework, could help to clarify the question of "how to teach" children to prevent drowning and engage young children in long-term physical activities.

Meta-Analysis Review
INTRODUCTION
The proportion of fatal nontraffic injuries that involve high levels of alcohol use or alcohol intoxication was assessed by cause of injury to generate alcohol-attributable fractions. Updated alcohol-attributable fractions can contribute to improved estimates of the public health impact of excessive alcohol use.
METHODS
Peer-reviewed and gray literature for 1995-2019 on 15 causes of fatal nontraffic injuries in the U.S., Canada, or Mexico were systematically reviewed, and state data systems were queried for available estimates of fatalities with recorded blood alcohol concentration levels and proportions of decedents with blood alcohol concentrations ≥0.10 g/dL by cause of injury. For each injury cause, alcohol-attributable fractions across studies were synthesized by meta-analysis of single proportions using generalized linear mixed models.
RESULTS
In total, 60 published studies and 40 additional population-level data points from 6 state data systems were included. The meta-analyzed alcohol-attributable fractions by cause of injury are as follows: air-space transport (0.03), aspiration (0.24), child maltreatment (0.09), drowning (0.31), fall injuries (0.37), fire injuries (0.34), firearm injuries (0.24), homicide (0.29), hypothermia (0.29), motor vehicle nontraffic crashes (0.42), occupational and machine injuries (0.08), other road vehicle crashes (railroad trespasser injuries) (0.63), poisoning (not alcohol) (0.20), suicide (0.21), and water transport (0.27), yielding an overall median alcohol-attributable fraction of 0.27.
DISCUSSION
Excessive alcohol use is associated with substantial proportions of violent and nonviolent injury deaths. These findings can improve the data used for estimating alcohol-attributable injury deaths and inform the planning and implementation of evidence-based strategies (e.g., increasing alcohol taxes, regulating alcohol outlet density) to prevent them.

CONTEXT
Despite the growing evidence regarding surf-related injuries, investigation seems to overlook the differences between professional and recreational surfers' injuries and their specific risk factors.
OBJECTIVE
This review aimed at identifying differences in injuries sustained by recreational and competitive surfers. It also presents research gaps and suggests recommendations for future injury research and prevention.
METHODS
Study search was conducted on MEDLINE/PubMed, SportDiscus and Web of Science databases. To be included studies needed to report original data, clearly specify if recreational and/or competitive surfers were included, provide information regarding acute surfing injuries and/or analyse data concerning those injuries.
RESULTS
17 studies were included in the analysis. All included studies had at least Oxford Centre for Evidence-Based Medicine level of evidence 3. The percentage of recreational surfers sustaining at least one injury ranged from 31% to 35% in the 12 months prior to data collection and from 88% to 100% in lifetime while 42% to 49% and 81% to 100% of competitors were injured over the same periods. Competitive surfers appear to have a higher injury risk. Both recreational and competitive surfers appear to sustain more frequently skin, joint/ligament and muscle/tendon injuries affecting the lower limbs and caused by contact with their own equipment.
CONCLUSIONS
Competitive status, less surfing experience, older age and prior surgical injuries are risk factors for sustaining injuries while surfing. The most common types, anatomical locations and mechanisms of injury seem to be similar between recreational and competitive surfers.
