Review
BACKGROUND
Drowning is a significant public health issue, with females accounting for one third of global drowning deaths. The rate of female drowning has not decreased within high-income countries and presentations to hospital have increased. This scoping review aimed to explore adult female unintentional drowning, including risk factors, clinical treatment and outcomes of females hospitalised for drowning.
METHODS
A systematic search of the literature following the PRISMA-ScR framework was undertaken. The databases OVID MEDLINE, Embase, CINAHL, OVID Emcare, Web of Science, Informit and Scopus were accessed. Study locations of focus were Australia, Canada, New Zealand, the United Kingdom, and the United States. Studies from January 2003 to April 2019 were included. The quality of evidence of included studies was assessed using GRADE guidelines.
RESULTS
The final search results included 14 studies from Australia (n = 4), Canada (n = 1), New Zealand (n = 1), United States (n = 6), United Kingdom (n = 1), and one study reporting data from both Australia and United States. Nine studies reported risk factors for female drowning including age, with the proportion of female drowning incidence increasing with age. Although females are now engaging in risk-taking behaviours associated with drowning that are similar to males, such as consuming alcohol and swimming in unsafe locations, their exposure to risky situations and ways they assess risk, differ. Females are more likely to drown from accidental entry into water, such as in a vehicle during a flood or fall into water. This review found no evidence on the clinical treatment provided to females in hospital after a drowning incident, and only a small number of studies reported the clinical outcomes of females, with inconsistent results (some studies reported better and some no difference in clinical outcomes among females).
CONCLUSION
Adult females are a group vulnerable to drowning, that have lacked attention. There was no single study found which focused solely on female drowning. There is a need for further research to explore female risk factors, the clinical treatment and outcomes of females hospitalised for drowning. This will not only save the lives of females, but also contribute to an overall reduction in drowning.

Review
Volatile substance abuse is widespread among adolescents due to its easy availability and methods of consumption. Inhalant abuse represents a current problematic issue, causing significant morbidity and mortality due to direct toxicity on several target organs and displacement of gas which results in a lack of oxygen. This review aims to evaluate post-mortem and toxicological investigations in cases of suspected butane intoxication. We performed comprehensive research using the Preferred Reporting Items for Systematic Review (PRISMA) standards. Forty scientific papers fulfilled the inclusion criteria. A total of 58 cases of butane-related deaths were found. Among these, we found 11 cases of suicide (18%), 1 case of homicide (2%), 44 cases of accidental poisoning (76%), and 2 cases of work-related deaths (4%). Autopsy and post-mortem examinations were performed in 54 cases, whereas toxicological analyses were presented in 56 cases. In autopsy, pulmonary edema (51%) and poli-visceral congestion (59%) were the most common findings. When death by butane inhalation is hypothesized, autopsy and histological findings may be nonspecific, therefore toxicological investigations assume a crucial role along with attention to the methods used to collect biological samples.

Phosgene (COCl) gas is a chemical intermediate of high-volume production with numerous industrial applications worldwide. Due to its high toxicity, accidental exposure to phosgene leads to various chemical injuries, primarily resulting in chemical-induced lung injury due to inhalation. Initially, the illness is mild and presents as coughing, chest tightness, and wheezing; however, within a few hours, symptoms progress to chronic respiratory depression, refractory pulmonary edema, dyspnea, and hypoxemia, which may contribute to acute respiratory distress syndrome or even death in severe cases. Despite rapid advances in medicine, effective treatments for phosgene-inhaled poisoning are lacking. Elucidating the pathophysiology and pathogenesis of acute inhalation toxicity caused by phosgene is necessary for the development of appropriate therapeutics. In this review, we discuss extant literature on relevant mechanisms and therapeutic strategies to highlight novel ideas for the treatment of phosgene-induced acute lung injury.

Review
Poly (ADP-ribose) polymerase (PARP) inhibitors are a class of small-molecule drugs suppressing PARP enzymes activity, inducing the death of cells deficient in homologous recombination repair (HRR). HRR deficiency is common in tumor cells with BRCA gene mutation. Since their first clinical trial in 2003, PARP inhibitors have shown benefit in the treatment of HRR-deficient tumors. Recently, several randomized clinical trials (RCTs) have been conducted to investigate the potential benefit of administration of PARP inhibitors in cancer patients. However, the results remain controversial. To evaluate the efficiency and safety of PARP inhibitors in patients with cancer, we performed a comprehensive meta-analysis of RCTs. According to our study, PARP inhibitors could clearly improve progression-free survival (PFS), especially in patients with BRCA mutation. However, our study showed no significant difference in overall survival (OS) between the PARP inhibitors and controls, even in the BRCA mutation group. Little toxicity was reported in the rate of treatment correlated adverse events (AEs) in PARP inhibitor group compared with controls. In conclusion, PARP inhibitors do well in improving PFS with little toxicity, especially in patients with BRCA deficiency.

Review
BACKGROUND
Alcohol consumption has been linked with injuries through motor vehicle crashes, falls, drowning, fires and burns, and violence. In the US, half of the estimated 100,000 deaths attributed to alcohol each year are due to intentional and unintentional injuries. The identification of effective interventions for the reduction of unintentional and intentional injuries due to problem drinking is, therefore, an important public health goal.
OBJECTIVES
To assess the effect of interventions for problem drinking on subsequent injury risk.
SEARCH STRATEGY
We searched 12 twelve computerized databases: MEDLINE (1966-8/96), EMBASE (1982-1/97), Cochrane Controlled Trials Register (1997, issue #1), PsycINFO (1967-1/97), CINAHL (1982-10/96), ERIC (1966-12/96), Dissertation Abstracts International (1861-11/96), IBSS (1961-1/97), ISTP (1982-1/97) and three specialized transportation databases, using terms for problem drinking combined with terms for controlled trials; bibliographies of relevant trials; and contact with authors and government agencies. The electronic and bibliographic searches were updated in May 2002.
SELECTION CRITERIA
Randomized controlled trials of interventions among participants with problem drinking, which are intended to reduce alcohol consumption or to prevent injuries or their antecedents, and which measured injury-related outcomes.
DATA COLLECTION AND ANALYSIS
Two authors extracted data on participants, interventions, follow-up, allocation concealment, and outcomes, and independently rated allocation concealment quality.
MAIN RESULTS
Of 23 eligible trials identified, 22 had been completed and 17 provided results for relevant outcomes. Completed trials of problem drinkers that compared interventions for problem drinking to no intervention reported reduced motor-vehicle crashes and related injuries, falls, suicide attempts, domestic violence, assaults and child abuse, alcohol-related injuries and injury emergency visits, hospitalizations and deaths. Reductions ranged from 27% to 65%. Because few trials were sufficiently large to assess effects on injuries, individual effect estimates were generally imprecise. We did not combine the results quantitatively because the interventions, patient populations, and outcomes were so diverse. The most commonly evaluated intervention was brief counseling in the clinical setting. This was studied in seven trials, in which injury-related deaths were reduced: relative risk (RR) 0.65; 95% confidence interval (CI) 0.21 to 2.00. However, this reduction may have been due to chance. The majority of trials of brief counseling also showed beneficial effects on diverse non-fatal injury outcomes.
REVIEWERS' CONCLUSIONS
Interventions for problem drinking appear to reduce injuries and their antecedents (e.g. falls, motor vehicle crashes, suicide attempts). Because injuries account for much of the morbidity and mortality from problem drinking, larger studies are warranted to evaluate the effect of treating problem drinking on injuries.

Review
BACKGROUND
In most industrialized countries, drowning ranks second or third behind motor vehicles and fires as a cause of unintentional injury deaths to children under the age of 15. Death rates from drowning are highest in children less than five years old. Pool fencing is a passive environmental intervention designed to reduce unintended access to swimming pools and thus prevent drowning in the preschool age group. Because of the magnitude of the problem and the potential effectiveness of fencing we decided to evaluate the effect of pool fencing as a drowning prevention strategy for young children.
OBJECTIVES
To determine if pool fencing prevents drowning in young children.
SEARCH STRATEGY
We used Cochrane Collaboration search strategy of electronic databases, searched reference lists of past reviews and review articles, Cochrane International Register of RCT's, studies from government agencies in the United States and Australia, and contacted colleagues from International Society for Child and Adolescent Injury Prevention, World Injury Network, and CDC funded Injury Control and Research Centers.
SELECTION CRITERIA
In order to be selected a study had to be designed to evaluate pool fencing in a defined population and provide relevant and interpretable data which objectively measured the risk of drowning or near drowning or provided rates of these outcomes in fenced and unfenced pools. The completed studies meeting selection criteria employed a case-control design. No randomized controlled studies have been identified.
DATA COLLECTION AND ANALYSIS
Three published studies met selection criteria. Data were extracted by two reviewers using standard abstract form. Odds ratios with 95% CI, and incidence rates, were calculated for drowning and near-drowning. Attributable Risk percent (AR%) was calculated to report the reduction in drowning due to pool fencing.
MAIN RESULTS
Case control studies which evaluate pool fencing interventions indicate that pool fencing significantly reduces the risk of drowning. Odds ratio for the risk of drowning or near drowning in a fenced pool compared to an unfenced pool is 0.27 95%CI (0.16, 0.47). Isolation fencing (enclosing pool only) is superior to perimeter fencing (enclosing property and pool) because perimeter fencing allows access to the pool area through the house. Odds ratio for the risk of drowning in a pool with isolation fencing compared to a pool with three sided fencing is 0.17 95%CI (0.07, 0.44)
REVIEWER'S CONCLUSIONS
Pool fences should have a dynamic and secure gate and isolate (i.e., four-sided fencing) the pool from the house. Legislation should require isolation fencing with secure, self-latching gates for all pools, public, semi-public and private.

Review
BACKGROUND
Traumatic brain injury (TBI) is one of leading cause of death and disability in Iran that has serious consequences on people's health. Understanding of epidemiology of TBI can be helpful for policy making in health care management. Therefore, this study aimed to examine the epidemiology of TBI in Iran.
METHODS
PubMed, Web of Science, Scopus, Google scholar, and internal databases including, SID, Magiran, and IranMedex were searched to identify the relevant published studies up to Feb 2022. Moreover, the references list of key studies was scanned to find more records. The Joanna Briggs Institute (JBI) tool was used to assess the quality of included studies. The Excel and Comprehensive Meta-Analysis software were to analyze the data.
RESULTS
Overall, 23,446 patients from 15 studies were included in the study. The overall mean age of the patients was 31.36 ± 0.13 yr (95%CI: 31.10 to 31.61). The majority of the patients were male (74.37%), with a male to female ratio of 3:1. The incidence rate of TBI was 15.3 to 144 per 100,000 population. The mortality rate of TBI was estimated to be 10.4% (95%CI: 5% to 19%). The most common causes of injury were road traffic accidents (RTAs) (60%; 95%CI: 49% to 70%), and falling (20%; 95%CI: 16% to 26%), respectively. The most frequent type of head injury was subdural hematoma.
CONCLUSION
Our findings highlight that appropriate control and prevention strategies should be focused on male, road traffic accidents, and the group under 40 yr.

Comparative Study Meta-Analysis Review
BACKGROUND
Laparoscopic appendicectomy has gained wide acceptance as an alternative to open appendicectomy during pregnancy. However, data regarding the safety and optimal surgical approach to appendicitis in pregnancy are still controversial.
METHODS
This was a systematic review and meta-analysis of studies comparing laparoscopic and open appendicectomy in pregnancy identified using PubMed and Scopus search engines from January 1990 to July 2011. Two reviewers independently extracted data on fetal loss, preterm delivery, wound infection, duration of operation, hospital stay, Apgar score and birth weight between laparoscopic and open appendicectomy groups.
RESULTS
Eleven studies with a total of 3415 women (599 in laparoscopic and 2816 in open group) were included in the analysis. Fetal loss was statistically significantly worse in those who underwent laparoscopy compared with open appendicectomy; the pooled relative risk (RR) was 1·91 (95 per cent confidence interval (c.i.) 1·31 to 2·77) without heterogeneity. The pooled RR for preterm labour was 1·44 (0·68 to 3·06), but this risk was not statistically significant. The mean difference in length of hospital stay was - 0·49 (-1·76 to - 0·78) days, but this was not clinically significant. No significant difference was found for wound infection, birth weight, duration of operation or Apgar score.
CONCLUSION
The available low-grade evidence suggests that laparoscopic appendicectomy in pregnant women might be associated with a greater risk of fetal loss.

Cardiomyocyte death in the form of apoptosis and necrosis represents a major cellular mechanism underlying cardiac pathogenesis. Recent advances in cell death research reveal that not all necrosis is accidental, but rather there are multiple forms of necrosis that are regulated. Necroptosis, the earliest identified regulated necrosis, is perhaps the most studied thus far, and potential links between necroptosis and Cullin-RING ligases (CRLs), the largest family of ubiquitin E3 ligases, have been postulated. Cullin neddylation activates the catalytic dynamic of CRLs; the reverse process, Cullin deneddylation, is performed by the COP9 signalosome holocomplex (CSN) that is formed by eight unique protein subunits, COPS1/CNS1 through COPS8/CNS8. As revealed by cardiomyocyte-restricted knockout of (Cops8-cko) in mice, perturbation of Cullin deneddylation in cardiomyocytes impairs not only the functioning of the ubiquitin-proteasome system (UPS) but also the autophagic-lysosomal pathway (ALP). Similar cardiac abnormalities are also observed in Cops6-cko mice; and importantly, loss of the desmosome targeting of COPS6 is recently implicated as a pathogenic factor in arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C). Cops8-cko causes massive cardiomyocyte death in the form of necrosis rather than apoptosis and rapidly leads to a progressive dilated cardiomyopathy phenotype as well as drastically shortened lifespan in mice. Even a moderate downregulation of Cullin deneddylation as seen in mice with Cops8 hypomorphism exacerbates cardiac proteotoxicity induced by overexpression of misfolded proteins. More recently, it was further demonstrated that cardiomyocyte necrosis caused by Cops8-cko belongs to necroptosis and is mediated by the RIPK1-RIPK3 pathway. This article reviews these recent advances and discusses the potential links between Cullin deneddylation and the necroptotic pathways in hopes of identifying potentially new therapeutic targets for the prevention of cardiomyocyte death.

Meta-Analysis
OBJECTIVE
Considering the impact of mental illness and cancer on the society, the relationship between the two diseases should be assessed. This study aimed at determining the association between mental illness and cancer.
MATERIALS AND METHODS
The Embase and Medline databases were searched on October 21, 2020. Cohort, case-control, and cross-sectional studies were eligible for study inclusion. The Newcastle-Ottawa scale was used to qualitatively assess the risk of bias. Funnel plots were drawn to evaluate the risks of bias across the included studies.
RESULTS
We included 58 studies from 16 countries, incorporating approximately 30 national databases and 25 million individuals. Patients with psychiatric disorders did not show an increased risk of developing cancer. However, patients with cancer had a significantly increased risk of developing mental illness. The survival rates of patients with mental illness according to cancer occurrence and patients with cancer according to mental illness occurrence were significantly decreased.
CONCLUSIONS
Clinicians should conduct early screening to ensure that appropriate interventions for mental illness are administered in patients with cancer. Due to the high incidence of death in patients with mental illnesses due to unnatural causes, such as suicide, homicide, and accidents, clinicians should be aware of the importance of the treatment and management of these patients.
