Abstract
OBJECTIVE The aim of this study was to determine the perinatal death experience of midwifery students during clinical practice and their coping methods. DESIGN A qualitative, descriptive, phenomenological design was used. SETTINGS The study was conducted with midwifery students. PARTICIPANTS The study was conducted with 14 midwifery students at a state university in northern Turkey between April and July 2023. METHODS Perinatal death experiences that students witnessed during clinical practice and their coping methods were analyzed using the individual in-depth interview technique. Data were analyzed using the thematic analysis method. The results obtained from the study were reported according to the COREQ criteria. FINDINGS As a result of the analysis, four main themes: (1) the perception of the concept of death, (2) the first encounter with death, (3) methods of coping with death, and (4) students' suggestions were elicited from the data. Students who witnessed perinatal death were affected by this situation, experienced negative emotions, and resorted to different methods to cope with their negative feelings about death. CONCLUSIONS Midwifery students who witnessed perinatal death were negatively affected emotionally and professionally; therefore, education and policy-oriented regulations are needed to cope with perinatal death.

Abstract
OBJECTIVES The ways in which children understand dying and death remain poorly understood; most studies have been carried out with samples other than persons with an illness. The objective of this study was to understand the process by which children directly involved with life-limiting conditions understand dying and death. METHODS This qualitative study obtained interview data from N = 44 5-18-year-old children in the USA, Haiti, and Uganda who were pediatric palliative care patients or siblings of patients. Of these, 32 were children with a serious condition and 12 were siblings of a child with a serious condition. Interviews were recorded, transcribed, verified, and analyzed using grounded theory methodology. RESULTS Loss of normalcy and of relationships emerged as central themes described by both ill children and siblings. Resilience, altruism, and spirituality had a bidirectional relationship with loss, being strategies to manage both losses and anticipated death, but also being affected by losses. Resiliency and spirituality, but not altruism, had a bidirectional relationship with anticipating death. Themes were consistent across the 3 samples, although the beliefs and behaviors expressing them varied by country. SIGNIFICANCE OF RESULTS This study partially fills an identified gap in research knowledge about ways in which children in 3 nations understand dying and death. While children often lack an adult vocabulary to express thoughts about dying and death, results show that they are thinking about these topics. A proactive approach to address issues is warranted, and the data identify themes of concern to children.

Abstract
By a comparison between the definition of life and death in Modern Medicine and Avicenna's view, it is perceived that each of them has looked at the above concepts from their special perspective. The topic of Avicenna's view is the being of life and the topic of Modern Medicine is the origin, appearance, and impressions of life. In his philosophical and medical works, Avicenna described the separation of the soul from the body as the ultimate reason for ceasing life. On the other, with the accepted medical standards, death is attributed to the organs in the human body and relies on the function or lack of function in the body's organs. Despite the differences between these two fields of knowledge, there can be collaboration between science and philosophy to achieve significant results in this regard to make useful contributions to the clarification of the concept of life and death. The findings of the study demonstrate that although the question of life and death is investigated in Avicenna's philosophy as a transcendental issue and in modern medicine as a material one, a general-specific relationship can be made between science and philosophy in defining the concept of life and death in the natural world domain.

Abstract
Objective This retrospective analysis examined serious adverse events (SAEs) and deaths in U.S. lifestyle clinical trials aimed at enhancing cognitive health in older adults. Methods Data was gathered from trials completed between January 1, 2000, and July 19, 2023, via ClinicalTrials.gov's API. Results Among these trials, 76% did not report results. The remaining studies fell into four intervention categories: Cognitive/Behavioral, Exercise/Movement, Diet/Supplement, and Multi-modal. When considering all trial types collectively, the findings suggest that lifestyle clinical trials are generally safe. There was no significant increase in the relative risk of experiencing an SAE in the intervention group compared to the control group. However, in terms of relative risk of death, an increase of 28% was observed in the intervention compared to the control, which was statistically significant (X2 (1, N = 36), p < 0.00688). Nevertheless, this increase did not surpass age-adjusted U.S. mortality rates. Assessing the data by intervention type, Diet/Supplement, and Multi-modal trials displayed an elevated relative risk of SAEs in the intervention. Diet/Supplement trials had a 16% increase (X2 (1, N = 2), p < 0.0263), and Multi-modal trials had a 365% increase (X2 (1, N = 5), p < 0.000213). Diet/Supplement trials also showed a 67% increased risk of death (X2 (1, N = 2), p < 0.000197). Conclusions These findings should be cautiously considered due to the low rate of reporting, but underscore the significance of reporting clinical trial results, enhancing transparency, and facilitating more accurate safety assessments in cognitive aging and lifestyle interventions for older adults.

Abstract
OBJECTIVES The aim of this study was to evaluate the individual and combined effects of maternal smoking during pregnancy (MSDP) and personal smoking on mortality and life expectancy. STUDY DESIGN A prospective cohort study based on the UK Biobank, with a median follow-up of 12.47 years. METHODS This study employed multivariate Cox regression to determine the relative risks of mortality from all causes and specific diseases according to maternal and/or personal smoking status and pack-years of smoking (0, 1-20, 21-30, >30). Additionally, this study estimated the additive interaction between the two exposures. Life table analyses were performed using the estimated age-specific mortality rates to forecast life expectancy. RESULTS Results indicated that MSDP elevated the risk of all-cause mortality (HR = 1.12, 95% CI: 1.09-1.15) and mortality due to neoplasms (HR = 1.10, 95% CI: 1.06-1.12), circulatory (HR = 1.13, 95% CI: 1.06-1.19), respiratory (HR = 1.27, 95% CI: 1.16-1.40) and digestive system diseases (HR = 1.22, 95% CI: 1.08-1.38). Notably, both multiplicative and additive interactions were observed between maternal and personal smoking, with Relative Excess Risk due to Interaction (RERI) values for mortality from all causes, neoplasms, circulatory, and respiratory diseases being 0.21, 0.22, 0.16, and 0.76, respectively. This study also found a trend towards shorter gained life expectancy when maternal smoking and increasing pack-years of personal smoking were combined. CONCLUSIONS In this cohort study of UK Biobank, MSDP was associated with an increased risk of all-cause mortality and reduced life expectancy, suggesting that quitting smoking during pregnancy might have health and longevity benefits for both generations.

Abstract
BACKGROUND The Pandemic Grief Risk Factors (PGRFs) was developed as a self-report tool to compile a comprehensive list of unique risk factors related to grief when experiencing a coronavirus disease 2019 (COVID-19) loss. We explored the reliability and validity of the PGRF among healthcare workers who witnessed their patients' deaths during the COVID-19 pandemic. Further, we examined whether the general severity of PGRF may have been associated with work-related stress and pandemic grief reactions. METHODS An online survey was conducted among tertiary hospital healthcare workers (doctors and nursing professionals) who had witnessed the deaths of patients they cared for. Pandemic Grief Scale for healthcare workers, the Stress and Anxiety to Viral Epidemics-3 items, the Patient Health Questionnaire-9, and the Generalized Anxiety Disorder-7 responses were collected. RESULTS In total, 267 responses were analyzed. The single-factor structure of the Korean version of the PGRF showed a good fit for the model. The scale demonstrated good internal consistency and convergent validity with other depression and anxiety rating scales. The mediation analysis revealed that work-related stress directly influenced pandemic grief reactions positively, and depression, anxiety, and general severity of grief risk factors partially mediated the association positively. CONCLUSION Among healthcare workers who witnessed the deaths of their patients due to COVID-19, the Korean version of the PGRF was valid and reliable for measuring the overall severity of PGRF. The PGRF can be used to identify individuals at risk for dysfunctional grief.

Abstract
OBJECTIVES The objective was to investigate the benefits of the 'weekend warrior' physical activity pattern in Latin America, where many people take part in high levels of non-exercise physical activity. METHODS Participants in the Mexico City Prospective Study were surveyed from 1998 to 2004 and resurveyed from 2015 to 2019. Those who exercised up to once or twice per week were termed weekend warriors. Those who exercised more often were termed regularly active. Analyses were adjusted for potential confounders. RESULTS The main analysis included 26 006 deaths in 154 882 adults (67% female) aged 52±13 years followed for 18±4 years (mean±SD). Compared with those who reported no exercise, the HR (95% CI) was 0.88 (0.83 to 0.93) in the weekend warriors and 0.88 (0.84 to 0.91) in the regularly active. Similar results were observed for cardiovascular disease and cancer mortality, but associations were weaker. Stratified analyses showed that substantial reductions in all-cause mortality risk only occurred when the duration of exercise sessions was at least 30-60 min. The repeated-measures analysis included 843 deaths in 10 023 adults followed for 20±2 years. Compared with being inactive or becoming inactive, the HR was 0.86 (95% CI 0.65 to 1.12) when being a weekend warrior or becoming a weekend warrior and 0.85 (95% CI 0.70 to 1.03) when being regularly active or becoming regularly active. CONCLUSIONS This is the first prospective study to investigate the benefits of the weekend warrior physical activity pattern in Latin America. The results suggest that even busy adults could benefit from taking part in one or two sessions of exercise per week.

Abstract
Enduring intolerable suffering, an essential eligibility criterion in Medical Assistance in Dying (MAiD) in Canada and elsewhere, is a contradiction in terms, in that suffering must be tolerable to be endured. Cases of people who were approved for MAiD but who elected to die naturally, thus tolerating their suffering, bear out the unreliability of this central safeguard. The clinical assessment of intolerable suffering may be strengthened by adopting a definition of intolerable suffering centred on clinically evidenced physical and psychological decompensation. This argument also raises important questions about the risks of MAiD clinicians subjectively defining, approving and providing MAiD in ways that deviate from accepted legal and clinical concepts and ethics. Examples show some prolific clinicians describe MAiD in terminology that differs from such norms, as a personal mission, as personally pleasurable, and as a rights-based service. These alternative views are explored for their risks in assessing and providing MAiD for intolerable suffering. This further demonstrates the need for conceptual clarity in legislation, improved vetting and monitoring of clinicians, and a different assessment process to protect patients and clinicians.

Abstract
BACKGROUND Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is responsible for an important mortality rate worldwide. We aimed to evaluate the actual imputability of SARS-CoV-2 on the mortality rate associated with SARS-CoV-2-related illnesses in the pediatric intensive care unit (PICU). Secondary objectives were to identify risk factors for death. METHODS This national multicenter comparative study comprised all patients under 18 years old with positive SARS-CoV-2 polymerase chain reactions (PCRs) [acute corona virus disease 2019 (COVID-19) or incidental SARS-CoV-2 infection] and/or pediatric inflammatory multisystem syndrome (PIMS) recorded in the French PICU registry (PICURe) between September 1, 2021, and August 31, 2022. Included patients were classified and compared according to their living status at the end of their PICU stay. Deceased patients were evaluated by four experts in the field of pediatric infectiology and/or pediatric intensive care. The imputability of SARS-CoV-2 as the cause of death was classified into four categories: certain, very probable, possible, or unlikely, and was defined by any of the first three categories. RESULTS There were 948 patients included of which 43 died (4.5%). From this, 26 deaths (67%) could be attributed to SARS-CoV-2 infection, with an overall mortality rate of 2.8%. The imputability of death to SARS-CoV-2 was considered certain in only one case (0.1%). Deceased patients suffered more often from comorbidities, especially heart disease, neurological disorders, hematological disease, cancer, and obesity. None of the deceased patients were admitted for pediatric inflammatory multisystem syndrome (PIMS). Mortality risk factors were male gender, cardiac comorbidities, cancer, and acute respiratory distress syndrome. CONCLUSIONS SARS-CoV-2 mortality in the French pediatric population was low. Even though the imputability of SARS-CoV-2 on mortality was considered in almost two-thirds of cases, this imputability was considered certain in only one case.

Abstract
BACKGROUND With 11,558 deaths and 200,000 suicide attempts in 2019, France is among the European countries most affected. The aim of this study was to determine the costs and burden of suicides and suicide attempts in France (population 67 million). METHODS We estimated direct costs, comprising healthcare, as well as post-mortem costs including autopsy, body removal, funeral expenses, police intervention and support groups; indirect costs comprised lost productivity, daily allowances; the burden of disease calculations used a monetary value for death and disability based on incidence data. Data was obtained from the national statistics, health and social care database, registries, global burden of disease, supplemented by expert opinion. We combined top down and bottom up approaches. RESULTS The total costs and burden of suicides and suicide attempts was estimated at €18.5 billion and €5.4 billion, respectively. Direct costs were €566 million and €75 million; indirect costs were €3.8 billion and €3.5 billion; monetary value for death and disability was €14.6 billion and €1.3. The monetary value for death and disability represented 79.1% and 24.8% of total costs for suicide and suicide attempt respectively. Some costs were based upon expert opinion, caregivers' burden was not counted and pre COVID data only is reported. CONCLUSIONS In France, the total cost and burden of suicides and suicide attempts was several billion €, suggesting major potential savings from public health interventions.

Abstract
BACKGROUND Exposure to ambient ozone pollution causes health loss and even death, and both are the main risk factors for the disease burden worldwide. We comprehensively evaluated the ozone pollution-related disease burden. METHODS First, numbers and age-standardized rates of deaths and disability-adjusted life years (DALYs) were assessed globally and by sub-types in 2019. Furthermore, the temporal trend of the disease burden was explored by the linear regression model from 1990 to 2019. The cluster analysis was used to evaluate the changing pattern of related disease burden across Global Burden of Disease Study (GBD) regions. Finally, the age-period-cohort (APC) model and the Bayesian age-period-cohort (BAPC) model were used to predict the future disease burden in the next 25 years. RESULT Exposure to ozone pollution contributed to 365,222 deaths and 6,210,145 DALYs globally in 2019, which accounted for 0.65 % of deaths globally and 0.24 % of DALYs globally. The disease burden was consistently increasing with age. Males were high-risk populations and low-middle socio-demographic index (SDI) regions were high-risk areas. The disease burden of ozone pollution varied considerably across the GBD regions and the countries. In 2019, the number of deaths and DALYs cases increased by 76.11 % and 56.37 %, respectively compared to those in 1990. The predicted results showed that the number of deaths cases and DALYs cases for both genders would still increase from 2020 to 2044. CONCLUSION In conclusion, ambient ozone pollution has threatened public health globally. More proactive and effective strategic measures should be developed after considering global-specific circumstances.

Abstract
INTRODUCTION Data on the association between kidney function and Takotsubo syndrome (TTS) outcomes are scarce and conflictive. OBJECTIVE To assess the impact of chronic kidney disease (CKD) and acute renal failure (ARF) in patients with TTS. MATERIAL AND METHODS Patients from the prospective nation-wide (RETAKO) registry were included and divided into quartiles of maximum creatinine (Cr) level during hospitalization. RESULTS The prevalence of CKD and ARF in the whole RETAKO cohort was 5.4% and 11.7%, respectively. Compared to Q1 (Cr <0.71), patients within Q4 (Cr > 1.1) had lower left ventricular ejection fraction on admission (38.5 ± 12 vs 43.3 ± 11.3, p = 0.002) and higher bleeding rates during hospitalization (6.7% vs 2%, p = 0.005). In addition, compared to Q1, Q4 patients have a greater incidence of cardiogenic shock (17.3% vs 5.6%, p < 0.001), and a higher rate of 5-year all-cause death and major adverse cardiovascular events (31.5% vs 15.8%, p < 0.001 and 22.5% vs 9.3%, p < 0.001, respectively). CONCLUSIONS TTS patients with CKD have a higher incidence of ARF and exhibit greater Cr on admission, which were linked with higher rates of cardiogenic shock, bleeding during hospitalization as well as major adverse cardiovascular events and all-cause death during a 5-year follow-up.

Abstract
INTRODUCTION Severe brain injury (SBI), including severe intraventricular haemorrhage (sIVH) and cystic periventricular leukomalacia, poses significant challenges for preterm infants, yet recent data and trends are limited. METHODS Analyses were conducted using the Australian and New Zealand Neonatal Network data on preterm infants born <32 weeks' gestation admitted at Monash Children's Hospital, Australia, from January 2014 to April 2021. The occurrence and trends of SBI and sIVH among preterm infants, along with the rates and trends of death and neurodevelopmental impairment (NDI) in SBI infants were assessed. RESULTS Of 1,609 preterm infants, 6.7% had SBI, and 5.6% exhibited sIVH. A total of 37.6% of infants with SBI did not survive to discharge, with 92% of these deaths occurring following redirection of clinical care. Cerebral palsy was diagnosed in 65.2% of SBI survivors, while 86.4% of SBI survivors experienced NDI. No statistically significant differences were observed in the temporal trends of SBI (adjusted OR [95% CI] 1.08 [0.97-1.20]; p = 0.13) or sIVH (adjusted OR [95% CI] 1.09 [0.97-1.21]; p = 0.11). Similarly, there was no statistically significant difference noted in the temporal trend of the composite outcome, which included death or NDI among infants with SBI (adjusted OR [95% CI] 0.90 [0.53-1.53]; p = 0.71). CONCLUSION Neither the rates of SBI nor its associated composite outcome of death or NDI improved over time. A notable proportion of preterm infants with SBI faced redirection of care and subsequent mortality, while most survivors exhibited adverse neurodevelopmental challenges. The development of better therapeutic interventions is imperative to improve outcomes for these vulnerable infants.

Abstract
BACKGROUND Cultural factors influence attitudes toward death, and gender disparities are evident. Prior studies show that medical students have limited knowledge about death and are uncomfortable with it. Moreover, there is limited research that has examined factors that influence medical students' knowledge and attitudes toward death. OBJECTIVES The objectives of the study were to compare cultural and gender differences in relation to knowledge and attitudes toward loss and grief and to screen for complicated grief among medical students at the Arabian Gulf University and the University of Toronto. METHODS A cross-sectional study was disseminated to medical students at both universities in 2022. The variables in the survey included four parts: demographic characteristics of the participants, religious observance, history of encountering loss of a loved one, grief following loss, attitude toward death, and learning about how to deal with grief and death during medical school. The brief grief questionnaire and the death attitude profile-revised scales were used. RESULTS The study sample consisted of 168 medical students, with 74.1% being female. Complicated grief scores were higher among Arabian Gulf University students (3.87 ± 2.39) than among University of Toronto students (2.00 ± 1.93) and were higher for participants with a higher degree of religious observance in both schools (p < 0.05). Death avoidance (p = 0.003), approach acceptance (p < 0.001), and escape acceptance (p = 0.038) domains were significantly higher among Arabian Gulf University students than among University of Toronto students. Almost three-quarters of University of Toronto students reported not being taught about grief, compared to 54% of Arabian Gulf University students. CONCLUSIONS Arabian Gulf University medical students scored higher on complicated grief, most likely due to cultural and religious factors. Females at both institutions as well as those who indicated a higher level of religious observance reported higher scores of complicated grief. The study highlights how cultural and religious beliefs influence medical students' attitudes toward death and bereavement. It provides valuable insight into the knowledge and attitudes of medical students toward loss.

Abstract
BACKGROUND Reports at the beginning of the COVID-19 pandemic suggested differences in COVID-19-associated mortality between individuals with serious mental disorders (SMD) and the population at large. AIM To compare the pattern of COVID-19-associated mortality in individuals with and without SMD in Sweden over the two main pandemic years. METHODS We compared the pattern of COVID-19-associated mortality in individuals with and without SMD in Sweden during 2020 and 2021. For SMD, we included psychotic disorder, bipolar disorder, and severe depression. The analysis was based on summary data from the Swedish Board of Health and Welfare covering the entire adult Swedish population. RESULTS The overall relative risk (RR) for experiencing a COVID-19-associated death was 1.66 (CI 1.50-1.83; p < 0.001) for individuals with SMD versus individuals without SMD. The corresponding RRs were 3.25 (CI 2.84-3.71; p < 0.001) for individuals with psychotic disorder, 1.06 (CI 0.88-1.26; p = 0.54) for individuals with bipolar disorder, and 1.03 (CI 0.80-1.32; p = 0.80) for individuals with severe depression. Compared to their respective counterparts in the non-SMD group, in the psychotic disorder and severe depression group, the RR were higher in women than in men. In the bipolar disorder group, the RR was higher in men than in women. The RR of COVID-19-associated death was generally higher in younger individuals with SMD. Individuals with psychosis between 18 and 59 years had the highest RR of COVID-19-associated death with 7.25 (CI 4.54-11.59; p<0.001). CONCLUSIONS Individuals with SMD, and particularly those with psychotic disorders, had a higher risk of COVID-19-associated death than the general population. As this is a pattern also seen with other infections, people with SMD may be similarly vulnerable in future pandemics.

Abstract
Brodifacoum exerts its antagonistic effect against the metabolism of vitamin K, an essential component in the synthesis of blood coagulation factors. This effect ultimately hinders the blood's capacity to clot effectively, rendering it a commonly employed rodenticide. Instances of lethal poisonings are exceedingly rare owing to expeditious medical intervention and treatment. Within this report, we present a case of brodifacoum-induced homicide, wherein the patient exhibited distinct clinical examinations and symptoms. Moreover, the patient's blood sample exhibited a noteworthy brodifacoum concentration of 0.681 µg/mL even after a period of 43 days following the incident of poisoning. Although an autopsy was not conducted due to religious restrictions, we endeavor to reasonably deduce the cause of death and furnish corroborative evidence for clinical diagnosis, treatment, and forensic examination in instances involving brodifacoum poisoning.

Abstract
BACKGROUND Timely recognition of dying is important for high quality end-of-life care however, little is known about how clinicians recognise dying. Late recognition is common and can lead to futile treatment that can prolong or increase suffering and prevent a change in the focus of care. AIM To explore how clinicians caring for dying people recognise that they are in the last days or hours of life, as well as the factors that influence the recognition of dying. DESIGN A systematically constructed integrative review of the literature. METHODS Medline, Scopus, Cumulative Index to Nursing and Allied Health Literature, PsycInfo and Allied and Complementary Medicine were searched in July 2022. Papers were included if they were original research, discussed how clinicians recognise dying, available in English language and published in 2012 or later. A constant comparison approach was applied to the analysis and synthesis of the literature. RESULTS 24 papers met the inclusion criteria. There were 3 main categories identified: 'Clues and signals' refers to prompts and signs that lead a clinician to believe a person is dying, incorporating the sub-categories 'knowing the patient over time', and 'intuition and experience'. 'Recognition by others' is where clinicians come to recognise someone is dying through others. This can be through a change in the context of care such as a tool or care plan or by communication with the team. 'Culture, system and practice' refers to the cultural beliefs of a setting that influences awareness of dying and denial of death as a possibility and avoidance of naming death and dying directly. System and practice of the setting also impact on recognition of dying. This involves work pace and intensity, shift systems and timing of senior reviews of patients. Uncertainty and its impact on recognition of dying are evident throughout the findings of this review. The seeking of certainty and the absence of the possibility of dying contributes to late recognition of dying. DISCUSSION Recognition of dying is a complex process that occurs over time, involving a combination of intuition and gathering of information, that is influenced by contextual factors. A culture where dying is not openly acknowledged or even named explicitly contributes to late recognition of dying. A shared language and consistent terminology for explicitly naming dying are needed. Uncertainty is intrinsic to the recognition of dying and therefore a shift to recognising the possibility of dying rather than seeking certainty is needed. REGISTRATION (PROSPERO) CRD42022360900.

Abstract
OBJECTIVE The study analyzed the clinical features of children who had severe influenza and discussed on the risk factors associated with death in this population. METHODS A total of 167 children with severe influenza admitted to the intensive care unit of our hospital from January 2018 to August 2023 were selected and divided into the death group (27 cases) and the survival group (140 cases). Demographic characteristics and clinical data were collected and compared between the two groups. Logistic regression analysis was used to explore the risk factors for death in children with severe influenza. RESULTS The male-to-female ratio of the 167 children with severe influenza was 2.21:1, the median age was 3 years, and influenza A accounted for 70.66%. The CD4+ T cells percentage and CD4/CD8 were lower in the death group; the percentage of comorbid underlying diseases, mechanical ventilation, other systemic involvement, comorbid associated encephalopathy or encephalitis, and red blood cell distribution width (RDW), lactate dehydrogenase, activated partial thromboplastin time (APTT), and interleukin 6 were higher in the death group. The mechanical ventilation, associated encephalopathy or encephalitis, RDW, APTT, and CD4/CD8 were the independent risk factors for death. CONCLUSION Mechanical ventilation, comorbid encephalopathy or encephalitis, increased RDW, prolonged APTT, and decreased CD4/CD8 are independent risk factors for death in children with severe influenza.

Abstract
BACKGROUND Remote monitoring (RM) of implantable cardiac devices provides substantial and complex information, presenting new challenges such as detection of a patient's death. OBJECTIVE This study aims to describe RM transmissions indicating death and propose a management strategy for services. METHODS The study included consecutive ambulatory outpatients whose deaths were detected via RM. Clinical and device data were collected from electronic records, and ethical approval was obtained from the service's institutional review board. RESULTS Over a 9-year period (2014-2023), 28 patients were detected. The deceased patients had implantable cardioverter-defibrillators, pacemakers, and implantable loop recorders. In 54% of the cases, the patient's death had already been recognized. Alert transmissions indicating death were commonly related to ventricular arrhythmia events, but also due to lead measurements, and implantable loop recorder battery status. Several diagnostic features may indicate a patient's death. The most reliable was the presenting electrogram, demonstrating base rate pacing with no capture. Device diagnostics, lead parameters, and arrhythmia recordings may indicate death; however, not all cases present with recordings and diagnosis may not be conclusive. A majority (82%) had ventricular arrhythmia at the time of death. In cases where defibrillator shocks were delivered, the arrhythmia reinitiated shortly after successful cardioversion. Delayed therapy was observed, and some patients did not receive defibrillator shocks because of discriminators or because the arrhythmia rate fell below the shock zone. CONCLUSION Detecting a patient death via RM presents unique challenges and considerations for services. Standard operational policies and legal consultation should be established to address the implications.

Abstract
BACKGROUND & AIMS Non-alcoholic fatty liver disease (NAFLD) or, as recently renamed, metabolic dysfunction-associated steatotic liver disease (MASLD), has common metabolic pathways with diabetes and cardiovascular disease (CVD). Non-invasive tools (NITs) for liver steatosis and steatohepatitis (MASH) were studied as potential predictors of diabetes, cardiovascular disease (CVD) and mortality over a 20-year period. METHODS In 2001-02, 3042 individuals from the Attica region of Greece were recruited randomly, and were stratified by subgroups of sex, age and region to reflect the general urban population in Athens, Greece. Validated NITs for hepatic steatosis (Hepatic Steatosis Index (HIS), Fatty Liver Index (FLI), Lipid Accumulation Product (LAP), NAFLD liver fat score (NAFLD-LFS)) and steatohepatitis (Index of non-alcoholic steatohepatitis (ION), aminotransferase-creatinine-clearance non-alcoholic steatohepatitis (acNASH)) were calculated. Incidence of diabetes, CVD and mortality were recorded 5, 10 and 20 years later. RESULTS Within a 20-year observation period, the diabetes and CVD incidence was 26.3% and 36.1%, respectively. All hepatic steatosis and steatohepatitis NITs were independently associated with diabetes incidence. ION and acNASH presented independent association with CVD incidence [(Hazard Ratio (HR)per 1 standard deviation (SD) = 1.33, 95% Confidence Interval (95% CI) (1.07, 1.99)) and (HRper 1 SD = 1.77, 95% CI (1.05, 2.59)), respectively]. NAFLD-LFS which is a steatosis NIT indicating features of steatohepatitis, was linked with increased CVD mortality (HRper 1 SD = 1.35, 95% CI (1.00, 2.30)) and all-cause mortality (HRper 1 SD = 1.43, 95% CI (1.08, 2.01)). Overall, steatohepatitis NITs (i.e., ION and acNASH) presented stronger associations with the outcomes of interest compared with steatosis NITs. Clinically important trends were observed in relation to diabetes and CVD incidence progressively over time, i.e. 5, 10 and 20 years after baseline. CONCLUSIONS Easily applicable and low-cost NITs representing steatohepatitis may be early predictors of diabetes and CVD onset. More importantly, these NITs increased the attributable risk conveyed by conventional CVD risk factors by 10%. Thus, their potential inclusion in clinical practice and guidelines should be studied further.

Abstract
Purpose Advance directives (ADs) are legal documents that outline a person's preferences or decisions regarding end-of-life care ahead of time. In Korea, there is insufficient awareness and knowledge about ADs among patients undergoing hemodialysis. This study explored the relationship between perceptions of a good death, knowledge about ADs, and attitudes toward ADs in this patient population. Methods This cross-sectional survey enrolled 119 hemodialysis patients from a secondary hospital in 2021. The participants completed a self-administered questionnaire, and the data were analyzed using the t-test, analysis of variance, Pearson correlation coefficients, Spearman rank correlation coefficients, and multiple regression analysis. Results The average score for perceptions of a good death among hemodialysis patients was 2.80 out of 4, with clinical symptoms identified as the most critical factor. The average scores for knowledge about ADs and attitudes toward ADs were 5.69 out of 9 and 2.79 out of 4, respectively. There was a positive correlation between perceptions of a good death and attitudes toward ADs (r=0.34, P<0.001), as well as between knowledge about Ads and attitudes toward ADs (r=0.19, P=0.037). Factors influencing attitudes toward Ads included employment status (β=0.22, P=0.011), education level (β=0.22, P=0.013), and perceptions of a good death (β=0.29, P=0.001), which accounted for 24.8% of the variance in attitudes toward ADs. Conclusion A positive perception of a good death among patients undergoing hemodialysis was associated with a positive attitude toward ADs. Educational programs are needed to improve individuals' understanding of a good death and encourage the development of end-of-life care plans.

Abstract
This study aimed to characterize the changes in serum inflammatory mediators in hospitalized patients with COVID-19 correlating with death. The study includes 58 participants: i) inpatients (n = 37): patients suffering from severe acute respiratory syndrome due to COVID-19, who were admitted at Intensive Care Unit (ICU) recovered and who died and ii) control group (n = 21): community volunteers. Inflammatory mediators evaluated interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-10 (IL-10), interleukin-17 (IL-17), interferon-gamma (IFN-γ) and interferon-gamma protein levels (IFN-γ), as well as, Urea, LDH, D-dimer, TAP/INR, AST, ALT and lymphocytes. Our results suggest that high levels of inflammatory markers, such as pro-inflammatory cytokines, and laboratory parameters, such as low levels of lymphocytes and high levels of IL-6, are associated with disease severity, especially in individuals who died. Constant measurement and monitoring of these inflammatory parameters is an effective tool in clinical practice, and it can help choosing appropriate therapies during the course of the disease.

Abstract
BACKGROUND Erythropoietin (EPO) is a proposed drug for the treatment of neonatal hypoxic-ischemic encephalopathy (HIE). Multiple studies have linked its use, either as a monotherapy or in conjunction with therapeutic hypothermia (TH), with improved neonatal outcomes including death and neurodisability. However, there is also evidence in the literature that raises concerns about its efficacy and safety for the treatment of neonatal encephalopathy (NE). METHODS We searched MEDLINE, Cochrane CENTRAL, and Embase for both observational studies and randomized controlled trials (RCTs) investigating the effectiveness of EPO in treating NE. Only studies in which at least 300 U/kg of EPO was used and reported any one of the following outcomes: death, death or neurodisability, and cerebral palsy, were included. RESULTS Seven studies with 903 infants with the diagnosis of NE were included in our meta-analysis. EPO did not reduce the risk of death or neurodisability (risk ratio 0.68 [95% confidence interval [CI]: 0.43 to 1.09]) (P = 0.11). Similarly, the risk of cerebral palsy was not reduced by the administration of EPO (risk ratio 0.68 [95% CI: 0.33 to 1.40]) (P = 0.30). The risk of death was also not reduced at any dose of EPO regardless of the use of TH. CONCLUSIONS The results of our meta-analysis do not support the use of EPO for the treatment of neonatal encephalopathy. However, future large-scale RCTs are needed to strengthen these findings.

Abstract
The aim of this study was to compare the clinical characteristics between survivors and non-survivors after acute diquat (DQ) poisoning. Patients treated in the Emergency Department of Fu Yang People's Hospital for DQ poisoning between January 2018 and February 2022 were enrolled in this retrospective comparative study. A total of 65 patients were collected, including 36 males (55.4%) and 29 females (44.6%). There were 34 survivors (52.3%), and 31 non-survivors (47.7%). Patients in the non-survivor group were significantly older (P = 0.003), received a higher dose of DQ before admission (P < 0.001), had more severe organ damage (P < 0.001), lower respiration rate (P < 0.001) and enema (P = 0.009), lower GCS score (P = 0.038), and higher SIRS score (P = 0.018) and APACHE-II score (P < 0.001) than patients in the survivor group. Additionally, biochemical indicators after admission between survivors and non-survivors were significantly different (all P < 0.05). Multivariate logistic regression analysis showed that respiratory failure (P = 0.021), the dose of DQ (P = 0.022), respiratory rate (P = 0.007), and highest alanine transaminase (ALT) level after admission (P = 0.030) were independent risk factors for acute DQ-induced death. These data suggest that non-survivors with acute DQ poisoning are more likely to suffer from respiratory failure, have higher respiratory rate and ALT after admission, and are exposed higher doses of DQ before admission than survivors.

Abstract
Recent papers have emphasized the primary role of cellular information management in biological and evolutionary development. In this framework, intelligent cells collectively measure environmental cues to improve informational validity to support natural cellular engineering as collaborative decision-making and problem-solving in confrontation with environmental stresses. These collective actions are crucially dependent on cell-based memories as acquired patterns of response to environmental stressors. Notably, in a cellular self-referential framework, all biological information is ambiguous. This conditional requirement imposes a previously unexplored derivative. All cellular memories are imperfect. From this atypical background, a novel theory of aging and death is proposed. Since cellular decision-making is memory-dependent and biology is a continuous natural learning system, the accumulation of previously acquired imperfect memories eventually overwhelms the flexibility cells require to react adroitly to contemporaneous stresses to support continued cellular homeorhetic balance. The result is a gradual breakdown of the critical ability to efficiently measure environmental information and effect cell-cell communication. This age-dependent accretion governs senescence, ultimately ending in death as an organism-wide failure of cellular networking. This approach to aging and death is compatible with all prior theories. Each earlier approach illuminates different pertinent cellular signatures of this ongoing, obliged, living process.

Abstract
INTRODUCTION Carbon monoxide (CO) poisoning is a significant concern in forensic medicine, as it often presents unique challenges in terms of diagnosis, investigation, and determination of the cause of death. CO is a colourless, odourless, and tasteless gas that can be lethal when inhaled in high concentrations. It binds strongly to haemoglobin, forming carboxyhaemoglobin (COHb), which reduces the oxygen-carrying capacity of the blood, leading to tissue hypoxia and ultimately death. MATERIALS AND METHODS Circumstantial data, medical history information, autopsy findings, and toxicological analysis results related to 24 CO poisoning cases at the Institute of Legal Medicine in Verona were collected and analysed. The data were examined in an integrated manner to identify correlations and common patterns. A comparison was also made with the data available in the literature. RESULTS The male gender was confirmed to be the most frequently involved. COHb levels were found to be less than 50% in 6 cases. Three individuals had concurrent cardiovascular pathologies, while 11 subjects tested positive for various substances, including alcohol, benzodiazepines, and morphine. In most cases, the manner of fatal intoxication was accidental, although 6 suicides and 1 homicide are reported. CONCLUSIONS The Verona case series demonstrates that deaths due to CO poisoning require a multidisciplinary approach. The integration of diverse expertise is essential for assessing the manner of death. This approach enables a comprehensive evaluation of the available data, aids in distinguishing between accidental, suicidal, and homicidal deaths, and ensures accurate and reliable forensic conclusions.

Abstract
Although amyloid material in the heart is not infrequently encountered at autopsy it may on occasion be difficult to determine the significance in terms of possible contributions to the terminal mechanisms of death. A review was undertaken of the literature and of autopsy cases at Forensic Science SA over a 20-year-period (2003-2022) for all cases where significant amyloid material had been encountered on microscopy of the heart. Sixteen cases were found consisting of 11 cases where cardiac amyloid was involved in the lethal episode, and five where it was considered an incidental feature. Of the 11 lethal cases, there were three where cardiac amyloidosis was the cause of death, and eight where it was a contributing factor, along with ischaemic heart disease (N = 7) and bronchopneumonia (N = 1). The age range was 47-92 years, average 78.6 years, with a male to female ratio of 10:1. The weights of the hearts ranged from 496 to 1059 g - average 648 g. Of the five cases where it was considered an incidental finding, the causes of death were blunt head trauma (N = 2), small intestinal ischaemia (N = 2) and small intestinal obstruction (N = 1). The weights of the hearts ranged from 299 to 487 g, average 369 g. The most relevant types of amyloidosis in forensic cases tend to be light chain amyloidosis, senile cardiac amyloidosis and familial amyloid cardiomyopathy. Other forms of amyloidosis that affect the heart, which include reactive amyloidosis, haemodialysis-related amyloidosis and isolated atrial amyloidosis, either have minimal or no clinical significance, or are of uncertain significance. While it may be difficult to determine the prognostic significance of amyloid material at autopsy clinicopathological correlation may provide useful supportive information.

Abstract
Health benefits from urban greening are assumed to translate into reduced healthcare expenditure, yet few studies have tested this. A total of 110,134 participants in the Sax Institute's 45 and Up Study in the Australian cities of Sydney, Newcastle, or Wollongong were linked with hospital cost data for cardiovascular disease (CVD) events (e.g., acute myocardial infarctions) up to 30 June 2018. Associations between percentages of total green space, tree canopy, and open grass within 1.6 km of participants homes and annual per person measured CVD-related hospital costs were analysed using generalised linear model (GLM) with gamma density as a component of a two-part mixture model, adjusting for confounders. Overall, 26,243 participants experienced a CVD-related hospitalisation. Incidence was lower among participants with 10 % more tree canopy (OR 0.98, 95 %CI 0.96, 0.99), but not with higher total green space or open grass percentages. Total costs of hospitalisations per year were lower with 10 % more tree canopy (means ratio 0.96, 95 %CI 0.95, 0.98), but also higher with 10 % more open grass (means ratio 1.04, 95 %CI 1.02, 1.06). It was estimated that raising tree canopy cover to 30 % or more for individuals with currently less than 10 % could lead to a within-sample annual saving per person of AU$ 193 overall and AU$ 569 for those who experienced one or more CVD-related hospital admissions. This projects to an estimated annual health sector cost reduction of AU$ 19.3 million per 100,000 individuals for whom local tree canopy cover is increased from less than 10 % to 30 % or higher. In conclusion, this longitudinal study is among the first to analyse measured healthcare cost data in relation to urban green space in general, and with differentiation between major types of greenery relevant to urban planning policies in cities around the world. In sum, this study advances an increasingly important and international focus of research by reporting on the lower burden of CVD and fewer associated hospitalisations stemming from upstream investments that protect and restore urban tree canopy, which not only translates into substantial reduced costs for the health sector, but also helps to create regenerative cities and flourishing communities.

Abstract
BACKGROUND The mortality rate among people under probation supervision in the community is greater than that among incarcerated people and that among the general population. However, there is limited research on the distinct vulnerabilities and risks underlying the causes of death in this population. In this retrospective cohort study, we examined the individual and criminal justice-related factors associated with different causes of death. Factors were assessed in relation to the type of supervision, distinguishing between those under post-custodial release and those serving a community sentence. RESULTS The study utilised the official data held by His Majesty's Prison and Probation Service in England and Wales on the deaths of men and women under probation supervision between 01 April 2019 and 31 March 2021 where the cause of death had been definitively recorded (n = 1770). The high risk of deaths primarily caused by external factors (i.e., suspected suicide (10%), homicide (5%), and drug-related death (26%)) in this population was confirmed. A Gaussian Graphical Model (GGM) demonstrated unique relationships with suspected suicide and drug-related deaths for known suicide risk, history of drug use and recent (< 28 days of death) enforcement action due to a breach of probation conditions. Our findings suggest that that familial violence and abuse may be relevant in suicide and drug-related deaths and that minority groups may experience disproportional risk to certain types of death. CONCLUSIONS This study identified unique risk indicators and modifiable factors for deaths primarily caused by external factors in this population within the health and justice spheres. It emphasised the importance of addressing health inequalities in this population and improved joint-working across health and justice. This involves ensuring that research, policies, training, and services are responsive to the complex needs of those under probation supervision, including those serving community sentences. Only then can we hope to see lower rates of death within this population.

Abstract
OBJECTIVE To explore the association of socioeconomic deprivation and racialised outcomes in competitive athletes with sudden cardiac arrest (SCA) in the USA. METHODS SCA cases from the National Center for Catastrophic Sports Injury Research (July 2014 to June 2021) were included. We matched Area Deprivation Index (ADI) scores (17 metrics to grade socioeconomic conditions) to the 9-digit zip codes for each athlete's home address. ADI is scored 1-100 with higher scores indicating greater neighbourhood socioeconomic deprivation. Analysis of variance was used to assess differences in mean ADI by racial groups. Tukey post hoc testing was used for pairwise comparisons. RESULTS 391 cases of SCA in competitive athletes (85.4% male; 16.9% collegiate, 68% high school, 10.7% middle school, 4.3% youth) were identified via active surveillance. 79 cases were excluded due to missing data (19 race, 60 ADI). Of 312 cases with complete data, 171 (54.8%) were white, 110 (35.3%) black and 31 (9.9%) other race. The mean ADI was 40.20 (95% CI 36.64, 43.86) in white athletes, 57.88 (95% CI 52.65, 63.11) in black athletes and 40.77 (95% CI 30.69, 50.86) in other race athletes. Mean ADI was higher in black versus white athletes (mean difference 17.68, 95% CI 10.25, 25.12; p=0.0036) and black versus other race athletes (mean difference 17.11, 95% CI 4.74, 29.47; p<0.0001). CONCLUSIONS Black athletes with SCA come from areas with higher neighbourhood socioeconomic deprivation than white or other race athletes with SCA. Our findings suggest that socioeconomic deprivation may be associated with racialised disparities in athletes with SCA.

Abstract
BACKGROUND The association between statin use and mortality in patients with deep vein thrombosis (DVT) has not been rigorously evaluated. METHODS We used the data in the RIETE registry to examine the association between statin use and mortality at 3 months. We used mixed effects survival models accounting for clinical covariates and clustering of patients in enrolling centers. RESULTS From January 2009 through April 2022, there were 46,440 patients with isolated DVT in RIETE (in the lower-limbs 42,291, in the upper limbs 4149). Of these, 21 % and 18 %, respectively, were using statins. Statin users were older than non-users (72 ± 12 vs. 62 ± 18 years), and more likely had diabetes, hypertension, prior myocardial infarction or ischemic stroke, or were receiving antiplatelets. The 3-month mortality rates were: 6.0 % vs. 5.8 %, respectively. On multilevel multivariable analysis, the adjusted hazard ratio (aHR) for all-cause death in statin users vs. non-users was 0.77 (95%CI: 0.69-0.86). The 3-month risk of death in statin users was significantly lower than in non-users in patients with upper-limb DVT (aHR: 0.81; 95%CI: 0.72-0.91), distal lower-limb DVT (aHR: 0.48; 95%CI: 0.32-0.72), or proximal lower-limb DVT (aHR: 0.69; 95%CI: 0.50-0.95), and in those receiving simvastatin (aHR: 0.73; 95%CI: 0.60-0.90), atorvastatin (aHR: 0.70; 95%CI: 0.59-0.85), or rosuvastatin (aHR: 0.47; 95%CI: 0.27-0.80). Major bleeding, used as a falsification endpoint, did not show an association with use of statins at 3-month follow-up. CONCLUSIONS Statin users with isolated DVT were at significantly lower risk for death at 3 months than non-users.

Abstract
This article presents two cases from a collaborative study among Tibetan monastic populations in India on the postdeath meditative state called tukdam (thugs dam). Entered by advanced Tibetan Buddhist practitioners through a variety of different practices, this state provides an ontological frame that is investigated by two distinct intellectual traditions-the Tibetan Buddhist and medical tradition on one hand and the Euroamerican biomedical and scientific tradition on the other-using their respective means of inquiry. Through the investigation, the traditions enact two paradigms of the body at the time of death alongside attendant conceptualizations of what constitutes life itself. This work examines when epistemologies of these two traditions might converge, under what ontological contexts, and through which correlated indicators of evidence. In doing so, this work explores how these two intellectual traditions might answer how the time course and characteristics of physiological changes during the postmortem period might exhibit variation across individuals. Centrally, this piece presents an epistemological inquiry delineating the types of valid evidence that constitute exceptional processes post-clinical death and their potential ontological implications.

Abstract
Grigori Yefimovich Rasputin, a confidant of Tsar Nicholas and his wife, was murdered by Prince Yussupov and his co-conspirators in the cellar of the prince's Moika Palace in St Petersburg, Russia, on the evening of December 30th, 1916 (December 17th in the Russian calendar). The narrative of his death is largely based on Prince Yussupov's published memoirs and has Rasputin being poisoned with cyanide, shot, bludgeoned, and finally drowned. A review of the available forensic material, however, shows a photograph with a contact gunshot wound to Rasputin's forehead. This would indicate that he was dead prior to being dropped into the Little Nevka River. His distaste for sweet foods and the absence of poison at autopsy would also suggest that the story of cyanide toxicity was fabricated. Yussupov's description of Purishkevich firing at Rasputin from a distance as he ran across the courtyard in an attempt to escape would also not be consistent with the post mortem photograph. The simplest version of the events would be that Rasputin was executed by a contact gunshot wound to the forehead when he visited the Yussupov Palace. While it appears that the events of that fateful evening have been embellished, it is certainly not uncommon for perpetrators of homicides to provide histories that are later shown to be at odds with the truth. Re-evaluation of historic cases may provide compelling evidence for alternative interpretations to the popular historic record.

Abstract
AIMS Studies showed that low-density lipoprotein cholesterol (LDL-C) to triglyceride (TG) ratio could be used as a predictive parameter of low-density lipoprotein oxidation in vivo and the level of small dense LDL-C. However, whether LDL-C/TG ratio is associated with stroke prognosis remains unclear. We investigated the associations of LDL-C/TG ratio with outcomes in patients with acute ischaemic stroke (AIS) or transient ischaemic attacks (TIA) and explored whether it produced more predictive value than LDL-C and TG. METHODS Data were derived from the Third China National Stroke Registry (CNSR-III). Multivariable Cox regression for stroke recurrence, composite vascular events and all-cause death and logistic regression for the poor functional outcome (modified Rankin Scale score 3-6) were used. RESULTS A total of 14123 patients were included. After adjusting for confounding factors, quartile 4 of LDL-C/TG ratio was associated with an increased risk of recurrent stroke (hazard ratio [HR], 1.27; 95% confidence interval [CI], 1.03-1.56), composite vascular events (HR,1.23; 95% CI, 1.00-1.52), death (HR,1.70; 95% CI, 1.13-2.54) and poor functional outcome (odds ratio, 1.34; 95% CI, 1.12-1.61) at 3 months follow-up compared with quartile 1. We also found that quartile 4 of LDL-C and TG was positively and negatively associated with poor functional outcome at 3 months, respectively. LDL-C/TG ratio performed better than LDL-C or TG in predicting clinical outcomes. CONCLUSIONS LDL-C/TG ratio was associated with the risk of stroke recurrence, composite vascular events, death and poor functional outcome in patients with AIS or TIA.

Abstract
AIM The purpose of this systematic review and meta-analysis was to evaluate the accuracy of the absence of cardiac motion on point-of-care echocardiography (PCE) in predicting termination of resuscitation (TOR), short-term death (STD), and long-term death (LTD), in adult patients with cardiac arrest of all etiologies in out-of-hospital and emergency department setting. METHODS A systematic review and meta-analysis was conducted based on PRISMA guidelines. A literature search in Medline, EMBASE, Cochrane, WHO registry, and ClinicalTrials.gov was performed from inspection to August 2022. Risk of bias was evaluated using QUADAS-2 tool. Meta-analysis was divided into medical cardiac arrest (MCA) and traumatic cardiac arrest (TCA). Sensitivity and specificity were calculated using bivariate random-effects, and heterogeneity was analyzed using I2 statistic. RESULTS A total of 27 studies (3657 patients) were included in systematic review. There was a substantial variation in methodologies across the studies, with notable difference in inclusion criteria, PCE timing, and cardiac activity definition. In MCA (15 studies, 2239 patients), the absence of cardiac activity on PCE had a sensitivity of 72% [95% CI 62-80%] and specificity of 80% [95% CI 58-92%] to predict LTD. Although the low numbers of studies in TCA preluded meta-analysis, all patients who lacked cardiac activity on PCE eventually died. CONCLUSIONS The absence of cardiac motion on PCE for MCA predicts higher likelihood of death but does not have sufficient accuracy to be used as a stand-alone tool to terminate resuscitation. In TCA, the absence of cardiac activity is associated with 100% mortality rate, but low number of patients requires further studies to validate this finding. Future work would benefit from a standardized protocol for PCE timing and agreement on cardiac activity definition.

Abstract
In order to analyze the clinical characteristics of death cases in the oral emergency department of the stomatological hospital, and to improve the first aid technique before and in hospitals, we collected the clinical data of death cases in the Department of Oral Emergency in Peking University School and Hospital of Stomatology from January 2010 to January 2023 for retrospective analysis. General cha-racteristics, such as the patients' gender, age, chief complaint, maxillofacial diseases, systemic underlying diseases, rescue situation, cause of death and seasonal distribution of death were summarized. The results showed that a total of 8 death cases (5 males and 3 females) occurred during the 13-year period, ranging in age from 40 to 86 years, with a median age of 66 years. Among the 8 patients, 5 reported bleeding from oral cancer, 1 reported chest tightness and dyspnea after oral cancer surgery, 1 reported loss of consciousness after maxillofacial trauma, and 1 reported oral erosion and aphagia. All the 8 patients had one or more underlying diseases, such as hypertension, coronary heart disease, diabetes, renal failure, and cerebral infarction, etc. and 2 of them showed dyscrasia. Among them, the cause of death in 5 cases was respiratory and circulatory failure caused by oral cancer rupture and hemorrhage or poor surgical wound healing and hemorrhage; 1 case was uremia and hyperkalemia leading to circulatory failure; 1 case was asphyxia caused by swelling of oral floor tissue after maxillofacial trauma; and the other case was acute myocardial infarction caused circulatory failure after oral cancer surgery. According to the vital state at the time of treatment, 6 patients had loss of consciousness, respiratory and cardiac arrest before hospital, and 2 patients suffered from loss of consciousness, respiratory and cardiac arrest during treatment. All the patients received cardiopulmonary resuscitation and some advanced life support measures, and the average rescue time was 46 min. Due to the low incidence of death in the oral emergency department, medical personel have little experience in first aid. First aid training and drills and assessment should be organized regularly. First aid facilities should be always available and regularly maintained by special personnel, such as electrocardiogram (ECG) monitor, defibrillator, simple breathing apparatus, oxygen supply system, negative pressure suction system, endotracheal intubation and tracheotomy equipment. The death cases mainly occurred in the elderly patients with oral cancer bleeding and systemic underlying diseases. Education of emergency awareness for the elderly patients with oral cancer after surgery should be enhanced. Medical staff should strengthen first aid awareness and skills.

Abstract
Foreign body ingestion in children is a frequent cause for medical consultation. Although most foreign bodies are spontaneously eliminated from the gastrointestinal tract, life-threatening complications such as gastrointestinal obstruction or perforation can occur. We report the case of a 6-year-old boy who died 2 days after the onset of nausea and abdominal pain, with no foreign body ingestion witnessed or reported in the previous days. Autopsy showed a diffuse peritonitis and a perforation of the transverse colon caused by three high-powered magnets stacked together, and attached to the outer stomach wall via a fourth magnet located in the stomach. The cause of death was peritonitis due to bowel perforation by ingested magnets, which were shown to have come from a toy belonging to the child. Ingestion of multiple high-powered magnets carries a high risk of gastrointestinal complications and can exceptionally have a fatal outcome, especially as it often goes unreported and causes non-specific gastrointestinal symptoms that can delay diagnosis and management. This case highlights the need to raise public awareness of the potential risks of ingesting such magnets and to strengthen safety standards to protect children from this serious health hazard.

Abstract
BACKGROUND Prior studies in patients with chronic obstructive pulmonary disease (COPD) had indicated a potential correlation between cadmium (Cd) exposure and reduction in lung function. Nevertheless, the influence of Cd exposure on the progression of COPD remained unknown. Exploring the relationship between Cd exposure and the progression of COPD was the aim of this investigation. METHODS Stable COPD patients were enrolled. Blood samples were collected and lung function was evaluated. Regular professional follow-ups were conducted through telephone communications, outpatient services, and patients' hospitalization records. RESULTS Each additional unit of blood Cd was associated with upward trend in acute exacerbation, hospitalization, longer hospital stay, and death within 2 years. Even after adjusting for potential confounding factors, each 1 unit rise in blood Cd still correlated with a rise in the frequencies of acute exacerbation, longer hospital stay, and death. Moreover, COPD patients with less smoking amount, lower lung function and without comorbidities were more vulnerable to Cd-induced disease deterioration. CONCLUSION Patients with COPD who have higher blood Cd concentration are susceptible to worse disease progression.

Abstract
AIMS The Southern European Atlantic diet (SEAD) is the traditional dietary pattern of northwestern Spain and northern Portugal, but it may resemble that of central, eastern, and western European countries. The SEAD has been found associated with lower risk of myocardial infarction and mortality in older adults, but it is uncertain whether this association also exists in other European populations and if it is similar as that found in its countries of origin. METHODS AND RESULTS We conducted a prospective analysis of four cohorts with 35 917 subjects aged 18-96 years: ENRICA (Spain), HAPIEE (Czechia and Poland), and Whitehall II (United Kingdom). The SEAD comprised fresh fish, cod, red meat and pork products, dairy, legumes and vegetables, vegetable soup, potatoes, whole-grain bread, and moderate wine consumption. Associations were adjusted for sociodemographic variables, energy intake, lifestyle, and morbidity. After a median follow-up of 13.6 years (range = 0-15), we recorded 4 973 all-cause, 1 581 cardiovascular, and 1 814 cancer deaths. Higher adherence to the SEAD was associated with lower mortality in the pooled sample. Fully adjusted hazard ratios and 95% confidence interval per 1-standard deviation increment in the SEAD were 0.92 (0.89, 0.95), 0.91 (0.86, 0.96), and 0.94 (0.89, 0.99) for all-cause, cardiovascular, and cancer mortality, respectively. The association of the SEAD with all-cause mortality was not significantly different between countries [Spain = 0.93 (0.88, 0.99), Czechia = 0.94 (0.89,0.99), Poland = 0.89 (0.85, 0.93), United Kingdom = 0.98 (0.89, 1.07); P for interaction = 0.16]. CONCLUSION The SEAD was associated with lower all-cause, cardiovascular, and cancer mortality in southern, central, eastern, and western European populations. Associations were of similar magnitude as those found for existing healthy dietary patterns.

Abstract
BACKGROUND Declining physical performance in old age is associated with a wide range of negative health-related outcomes. However, it is unclear which physical capabilities should be prioritized to obtain prognostic information in older adults. AIMS To examine the associations between the performance on several physical function tests and falls, disability, and death in a well-characterized sample of very old Italian adults. METHODS This was a prospective cohort study of older adults who lived in the mountain community of the Sirente geographic area in Central Italy. Physical performance was assessed using isometric handgrip strength (IHG), walking speed (WS) at a usual and fast pace, 5-time sit-to-stand test (5STS), and sit-to-stand power measures. Appendicular skeletal muscle mass was estimated from calf circumference using a validated equation. History of falls, incident falls, and disability status according to basic Activities of Daily Living (ADLs) were recorded over two years. Survival status was obtained from the participants' general practitioners and was confirmed by the National Death Registry over 10 years from enrolment. Linear, binary, and Cox regressions were performed to evaluate the association between physical performance measures and health outcomes. RESULTS The mean age of the 255 participants was 84.2 ± 5.1 years, and 161 (63.1%) were women. Logistic regression indicated that IHG was significantly associated with incident ADL disability, whereas specific sit-to-stand muscle power was an independent predictor of death. No significant associations were observed between physical function and falls. CONCLUSIONS Our findings indicate selective associations between physical function tests and the occurrence of negative events in very old adults, with poor IHG predicting disability and specific sit-to-stand muscle power being longitudinally associated with death.

Abstract
This article discusses the relationship between two theories about the badness of death, the Life-Comparative Account and the Gradualist Account, and two methods of operationalizing severity in health care priority setting, Absolute Shortfall and Proportional Shortfall. The aim is that theories about the badness of death can influence and inform the idea of the basis of severity as a priority setting criterion. I argue that there are strong similarities between the Life-Comparative Account and Absolute Shortfall, and since the Life-Comparative Account is one of the most reasonable accounts of the badness of death, this provides some support for using Absolute Shortfall. I also argue that it is difficult to find support for Proportional Shortfall from theories about the badness of death, and also, that it is difficult to find support for Gradualist Account from theories about severity.

Abstract
OBJECTIVE To explore associations of dentition status with frailty and death. METHODS Based on the "Chinese Longitudinal Healthy Longevity Survey (CLHLS) in 2002-2018", a prospective cohort study was conducted that 21,159 participants not frail and aged ≥ 65 were included at baseline. The outcome was frailty and death. Frailty index (FI) was constructed based on 44 health items. The mediation role of high sensitivity C-reactive protein (hs-CRP) was examined using cross-sectional data in 2008, 2011 and 2014. RESULTS The incidence density of frailty was 50.1 (95%CI: 48.8∼51.4) per 1,000 person-years. Compared with ≥ 20 natural teeth, the odds of frailty hazards were 1.27 (95%CI: 1.16∼1.39) times higher for < 20 natural teeth with dental prostheses, and were 1.24 (95%CI: 1.14∼1.35) times higher for < 20 natural teeth without dental prostheses; the odds of death hazards for < 20 natural teeth without dental prostheses were 1.36 (95%CI: 1.26∼1.45) times higher. Among participants with <20 natural teeth and without dental prostheses at baseline, the odds of frailty hazards for using dental prostheses were 0.48 (95%CI: 0.41∼0.56) times as high as those remaining not to use, and the odds of death hazards were 0.44 (95%CI: 0.39∼0.48) times as high. The cross-sectional data showed higher levels of hs-CRP explained 5∼6% of associations between dentition status and frailty. CONCLUSION Natural teeth <20 was associated with higher odds of frailty and death. Mediation analysis based on cross-sectional data offered clues for chronic inflammation pathway, yet this finding is still needed to be further verified.

Abstract
This article presents the evaluation of the therapeutic intervention course in situations of traumatic loss and grief, offered online by the Universidade do Estado do Amazonas, between April and August 2021, for volunteer professionals. A semi-structured questionnaire with open and closed questions was administered. The analysis of the 55 responses from volunteer professionals and 14 responses from individuals who received the intervention was based on the Kirkpatrick evaluation model.

Abstract
Depression is one of the key conditions addressed by the Mental Health Gap Action Programme (mhGAP) of WHO that can lead to self-harm and suicide. Depression is associated with low levels of neurotransmitters, which eventually play a key role in the progression and development of mental illness. The nitrogen-containing heterocyclic compounds exhibit the most prominent pharmacological profile as antidepressants. Pyrazoline, a dihydro derivative of pyrazole, is a well-known five-membered heterocyclic moiety that exhibits a broad spectrum of biological activities. Many researchers have reported pyrazoline scaffold-containing molecules as potential antidepressant agents with selectivity for monoamine oxidase enzyme (MAO) isoforms. Several studies indicated a better affinity of pyrazoline-based moiety as (monoamine oxidase inhibitors) MAOIs. In this review, we have focused on the recent advancements (2019-2023) in the development of pyrazoline-containing derivatives exhibiting promising inhibition of MAO-A enzyme to treat depression. This review provides structural insights on pyrazoline-based molecules along with their SAR analysis, in silico exploration of binding interactions between pyrazoline derivatives and MAO-A enzyme, and clinical trial status of various drug molecules against depression. The in-silico exploration of potent pyrazoline derivatives at the active site of the MAOA enzyme will provide further insights into the development of new potential MAO-A inhibitors for the treatment of depression.

Abstract
INTRODUCTION Obstructive sleep apnea (OSA) is one of the main risk factors for cardiovascular diseases and is associated with both morbidity and mortality. OSA has also been linked to arrhythmias and sudden death. OBJECTIVE To assess whether OSA increases the risk of sudden death in the non-cardiac population. METHODS This is a systematic review of the literature. The descriptors "sudden death" and "sleep apnea" and "tachyarrhythmias" and "sleep apnea" were searched in the PubMed/Medline and SciELO databases. RESULTS Thirteen articles that addressed the relationship between OSA and the development of tachyarrhythmias and/or sudden death with prevalence data, electrocardiographic findings, and a relationship with other comorbidities were selected. The airway obstruction observed in OSA triggers several systemic repercussions, e.g., changes in intrathoracic pressure, intermittent hypoxia, activation of the sympathetic nervous system and chemoreceptors, and release of catecholamines. These mechanisms would be implicated in the appearance of arrhythmogenic factors, which could result in sudden death. CONCLUSION There was a cause-effect relationship between OSA and cardiac arrhythmias. In view of the pathophysiology of OSA and its arrhythmogenic role, studies have shown a higher risk of sudden death in individuals who previously had heart disease. On the other hand, there is little evidence about the occurrence of sudden death in individuals with OSA and no heart disease, and OSA is not a risk factor for sudden death in this population.

Abstract
OBJECTIVE This study aimed to assess whether an obesity paradox (lower event rates with higher body mass index [BMI]) exists in participants with advanced chronic kidney disease (CKD) and chronic coronary disease in the International Study of Comparative Health Effectiveness of Medical and Invasive Approaches (ISCHEMIA)-CKD, and whether BMI modified the effect of initial treatment strategy. METHODS Baseline BMI was analyzed as both a continuous and categorical variable (< 25, ≥ 25 to < 30, ≥ 30 kg/m2). Associations between BMI and the primary outcome of all-cause death or myocardial infarction (D/MI), and all-cause death, cardiovascular death, and MI individually were estimated. Associations with health status were also evaluated using the Seattle Angina Questionnaire-7, the Rose Dyspnea Scale, and the EuroQol-5D Visual Analog Scale. RESULTS Body mass index ≥ 30 kg/m2 vs < 25 kg/m2 demonstrated increased risk for MI (hazard ratio [HR] [95% confidence interval] = 1.81 [1.12-2.92]) and for D/MI (HR 1.45 [1.06-1.96]) with a HR for MI of 1.22 (1.05-1.40) per 5 kg/m2 increase in BMI in unadjusted analysis. In multivariate analyses, a BMI ≥ 30 kg/m2 was marginally associated with D/MI (HR 1.43 [1.00-2.04]) and greater dyspnea throughout follow-up (P < .05 at all time points). Heterogeneity of treatment effect between baseline BMI was not evident for any outcome. CONCLUSIONS In the ISCHEMIA-CKD trial, an obesity paradox was not detected. Higher BMI was associated with worse dyspnea, and a trend toward increased D/MI and MI risk. Larger studies to validate these findings are warranted.

Abstract
BACKGROUND Central catheter-related bloodstream infections (CRBIs) can lead to severe complications, including suppurative thrombophlebitis, endocarditis, and metastatic infections. While complications due to CRBIs caused by Staphylococcus aureus (SA) are well-known, there are limited data regarding CRBIs caused by other bacteria. METHODS This 2-year retrospective single-center study of patients with CRBIs from a tertiary care hospital examined the hematogenous complications associated with CRBIs according to patient characteristics, central venous catheter (CVC) types, and causative bacteria. RESULTS All in all, 254 patients with confirmed CRBIs were included; 285 bacteria types were isolated, mainly Enterobacteriaceae (n = 94), coagulase-negative Staphylococci (CNS, n = 82), SA (n = 45), and non-fermenting Gram-negative bacteria (NGB, n = 45). Among the patients, 35 developed at least one hematogenous complication (14 %), including suppurative thrombophlebitis (n = 15), endocarditis (n = 7) and metastatic infections (n = 16). In multivariate analysis, hemodialysis, persistent bacteremia for at least 3 days, and CRBIs caused by SA were associated with increased risk for hematogenous complications, while previous curative anticoagulant treatment was associated with reduced risk. Diabetes, CVC maintenance, and hematogenous complications were associated with increased 3-month mortality. CONCLUSION A thorough investigation of hematogenous complications should be envisioned in patients with persistent bacteremia, particularly those with SA infections and those on hemodialysis.
