Autoerotic neck compression can involve any compression to the neck during individual sexual activity performed to heighten arousal. This retrospective study examines 72 such deaths occurring in Australia between 2000 and 2022. The study aims to provide detailed medico-legal interpretation of such deaths and recommendations for investigation within Australian contexts, and globally. Demographic analysis reveals a predominance of Caucasian males under 50 years of age, with diverse employment and health status. Pathological examination uncovers a spectrum of injuries, from superficial abrasions to rare skeletal and cartilaginous injuries, providing insights into the mechanics and characteristics of these fatalities. Contextual examination highlights sexual paraphernalia, evidence of genital stimulation, and isolation are consistent features in most autoerotic deaths within the sample. There was a wide variety of tool usage (ropes, belts, etc.), and geo-temporal features associated with autoerotic neck compression. The study provides comprehensive examination of the circumstances and characteristics of autoerotic neck compression which may assist in differentiation between suicidal and homicidal neck compression deaths such as hanging or ligature strangulation respectively. This study is an Australian first and is the first study of autoerotic asphyxial deaths to focus solely on deaths with a neck compression component. The study incorporates new variables and suggests ways these should be considered in future death investigations. The authors argue for delineation and subcategorization of autoerotic neck compression from other autoerotic asphyxial death due to their distinct injury characteristics and mechanism of injury.</p>","PeriodicalId":12341,"journal":{"name":"Forensic science international","volume":"367 ","pages":"112342"},"PeriodicalIF":2.2,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142853635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It generally occurs through mother-fetus interaction, twin pregnancies, and intergenerational transmission. MC is influenced by genetic and environmental factors such as toxic conditions, immunological suppression, and various diseases (influenza, COVID-19, etc.). Progenitor cells transferred from the fetus to the mother through fetal MC are known to differentiate into neurons in the maternal brain. Although the relationship between these cells and the brain is not fully understood, it is thought that they may play a role in the emergence of some mental illnesses. The long-term presence of microchimeric cells in the body by differentiating into various cell types such as the brain, heart, bone, liver, and lung can lead to the presence of two or more DNA sets in an individual. This can lead to confusion in forensic identification and sex determination processes. This review aims to provide a comprehensive review of the definition, transmission pathways, detection duration in the human body, associated diseases, analytical detection techniques, and the importance of MC in forensic sciences. In this context, it is aimed to draw attention to the potential dangers of MC and contribute to the justice system.

As an implication, arrhythmias concern many private, commercial and public-passenger-vehicle driving licence holders. In their practice, medical professionals can be asked to assess an arrhythmia patient's fitness to drive effectively. Due to the subject's complexity (requiring an extent of multidisciplinary competencies), the current guidances' heterogeneity and the possible ethical conflicts, the decision-making process becomes challenging and of particular concern to the doctor. To offer an applicable decision support system to doctors of various backgrounds to implement in their practice when asked to assess for fitness to drive in a patient with a suspected disease, a formulated diagnosis or subjected to therapy for cardiac rhythm disturbances, we started gathering the issues concerning the fitness assessment of drivers (or candidates) who present with any condition, symptom or treatment possibly or knowingly caused by cardiac rhythm disturbances. Subsequently, we reviewed the English-based literature, including various countries' published medical standards. Then, the overview was revised by local medical experts in clinical arrhythmology, electrophysiology and traffic medicine to reach a consensus statement at a local level. The result is an easily consultable operational protocol that lists conditions, symptoms or treatments caused or possibly caused by cardiac rhythm disturbances; the certifications required for the assessment of the driver (or candidate); the orientation about the fitness or unfitness to drive under the enlisted medical conditions (distinguishing between private and professional drivers); and the recommended time limits to revise the case. A particular focus is applied to patients subject to the remote monitoring system of an implantable cardiac device, as this innovative approach constitutes a solid and efficient instrument for an accurate evaluation of the patient's cardiovascular situation. Despite some limitations, mainly concerning the lack of information at the moment of the evaluation or the infrequency of the medical condition, this proposal offers a ready-to-use solution for doctors who are asked to give their professional (clinical or medico-legal) opinion about the fitness to drive of patients with an arrhythmia problem. As an advantage, the constant cooperation among professionals from different backgrounds, like electrophysiologists and traffic medicine experts, allows a more individual, less predetermined evaluation of the specific case.</p>","PeriodicalId":12341,"journal":{"name":"Forensic science international","volume":"367 ","pages":"112338"},"PeriodicalIF":2.2,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142817558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comprehensive understanding of this facet of decomposition science is important, given its broad applicability across ecological and forensic disciplines, and current lack of research which investigates the inter-dependencies between two critical components of the necrobiome (the microbiome and insect activity), and the consequences of this interdependency on mass loss and total body score. Here we investigated the relationships among these key aspects of the decay process. We experimentally manipulated these variables by physically excluding insects and chemically perturbing the external microbiome of piglet (Sus scrofa) carcasses and quantified the effects on mass loss and total body score, as well as insect pre-appearance interval and colonisation. We found that piglets in the insect excluded and microbially perturbed treatment groups exhibited a significant delay in reaching 50 + % of mass loss compared with control piglets with insect access and intact microbiome. However, only remains with insects excluded displayed a significantly slower rate of total mass loss throughout the majority of the experiment and remained a significantly higher mass at the endpoint of 11,000 accumulative degree hours. Additionally, all insect excluded and microbially perturbed treatment groups displayed significantly lower total body scores compared to control piglets at corresponding time points. We also observed a significant delay in insect pre-appearance interval and colonisation for piglets with perturbed microbiomes compared to control piglets. Our findings demonstrate the significance of interacting components of the necrobiome, and the power of manipulative experiments in revealing causal relationships between biota and decomposition rates.

In this study, we tested published age estimation tools that are based on either minisequencing or MPS on four body fluids (blood, saliva, buccal cells and semen). All samples were analyzed with both technologies and the age estimates were compared. Biological replicates were taken from ten (blood, saliva, buccal cells) or 12 individuals (semen) to assess the reproducibility of each tool. Our study demonstrates high accuracy in estimating chronological age for various body fluids using both technologies, except for semen. The mean absolute errors (MAEs) ranged from three to five years for blood, saliva and buccal cells, while semen exhibited a higher MAE of seven to eight years. Despite the overall good performance for blood, saliva, and buccal cells, significant discrepancies were observed for some individuals both between the two technologies or when compared to their chronological age. Conclusively, we demonstrated that forensic age estimation tools based on two different technologies are similarly accurate for blood, saliva and buccal cells, while the semen tools need some adjustments before implementation into forensic casework.
