Participants and Setting: The clinical reports of a Portuguese European Clinical Academic Center database were analyzed. An observational and prospective cohort study was performed. A descriptive analysis of the variables was conducted, considering gender, bimodal age groups, place of residence, offender data, place of occurrence, etiology, localization, type of injuries, personal injury assessment by Quantum doloris, and injury time. The statistical analysis was performed by Spearman’s rho and Kendall’s tau-b correlation tests, Pearson’s chi-square test of independence (χ2), and Mann–Whitney and Kruskal–Wallis nonparametric tests (P < 0.05). The relationship between age groups and the place of occurrence was statistically significant (P = 0.001). Orofacial and nonorofacial injuries were related (P = 0.035). The General Data Protection Regulation is not a barrier to the treatment and sharing of justified data but a framework for safeguarding individuals’ fundamental rights, including the Right to Health. Meticulous reporting of the clinical situation involves the victim, the occurrence, and the potential offender.","PeriodicalId":45852,"journal":{"name":"Forensic Sciences Research","volume":"28 3","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138598045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A search was conducted to identify relevant literature on missing persons using the Web of Science Core Collection database for the period 2000–2021. Subsequently, a knowledge map was constructed using CiteSpace software to perform a visual analysis of the distribution of authors and institutions, journals, national/regional distribution; citation frequency; high-frequency keywords; and emerging research hotspots. The results showed firstly that discussions on missing persons and related topics in East Asia are held at the regional scale. There is a paucity of research on this topic, which has been conducted on a limited scale, lacks depth and possibly innovation and entails limited discussion in this region. Secondly, there is a lack of social science research on missing persons and related topics worldwide. Thirdly, relevant research in East Asia should continue to preserve its own characteristics, effectively addressing current issues and enabling more people to participate in social science-oriented discussions focusing on the topic of missing persons. This approach provides a promising direction for pursuing the sustainable development of the topic of missing persons.","PeriodicalId":45852,"journal":{"name":"Forensic Sciences Research","volume":"21 6","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138596678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the repeat region (RR) and flanking region (FR) variations were detected at 58 short tandem repeats (STRs) by MPS, which could increase allelic diversity (34.59%) and gene diversity (3.95%) compared with the capillary electrophoresis (CE) method. Six novel RR variants were identified at 5 STRs, and eleven FR variants were found at 8 STRs. Concordance amounted to 99.96% (4598 out of 4600 alleles) between ForenSeq DNA Signature Prep Kit and CE kits, and discordance was due to bioinformatic misinterpretation at DXS7132. Additionally, allele frequencies and forensic parameters of 94 identity-informative single nucleotide polymorphisms (iiSNPs) provided a reference dataset, which held a higher power of discrimination (1–3.4825 × 10−35). A total of 29 FR variants were found at 24 target iiSNPs. The power of the system effectiveness with the combined 27 autosomal STRs by sequence and 94 iiSNPs was added more substantially than that of a single type of marker alone, such as the combined power of discrimination (CPD) and the combined power of exclusion (CPE) achieving 1–7.1358 × 10−65 and 1–4.4803 × 10−21, respectively. Population structure analyses with iiSNPs and additional ancestry-informative SNPs (aiSNPs) demonstrated that Chinese Xibe in the northeast was one of the East Asian populations. At the genetic level, Northeastern Xibe is close to populations where they live, such as Han Chinese and other ethnic minority groups.","PeriodicalId":45852,"journal":{"name":"Forensic Sciences Research","volume":"24 6","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138596610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Brown","doi":"10.3390/forensicsci3040040","DOIUrl":"https://doi.org/10.3390/forensicsci3040040","url":null,"abstract":"Motor vehicle accidents are a significant consequence of marijuana abuse. Limitations of its roadside detection and the forensic problems with establishing impairment require innovations that are scientifically achievable. Marijuana abuse currently is at an all-time high in the United States and its physiological effects make it a popular recreational drug that is reported to be a leading cause of preventable morbidity and mortality among the youth in the 18 most affluent nations. The medical benefits of drugs derived from marijuana complicate its forensic regulation. In an extensive 2017 report by The American Academy of Sciences, the evidence for the medical benefits of delta-9 tetrahydrocannabinol (derived from marijuana) were stated to be conclusive or substantial for the treatment of chronic pain in adults, as an antiemetic for treatment of chemotherapy-induced nausea and vomiting, and for improving patient-reported multiple sclerosis spasticity symptoms. The benefits from treatment for many other medical conditions were inconclusive or absent. The evidence is clear that safely driving a motor vehicle is significantly impaired while under the influence of marijuana. However, there is no roadside forensic test that reliably detects impairment, and there is an urgent need for such to protect the public while insuring the legal rights of users. There is strong societal pressure to relax marijuana’s forensic regulation, including removing it from Schedule I of the Controlled Substances Act. Artificial intelligence (AI) should be implemented with appropriate human control to resolve controversies.","PeriodicalId":45852,"journal":{"name":"Forensic Sciences Research","volume":"106 S7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135540384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The Presence of the Human Auditory Ossicles—Detected Postmortem by CT Scan—As a Taphonomic Indicator","authors":"Edda E. Guareschi, Sara Poggesi, Marco Palmesino, Paola A. Magni","doi":"10.3390/forensicsci3040039","DOIUrl":"https://doi.org/10.3390/forensicsci3040039","url":null,"abstract":"Introduction: Three tiny bones compose the human ossicular chain: malleus, incus and stapes. Also known as auditory ossicles, they are united by joints in the middle ear cavity of the petrous part of the temporal bone. Completely developed two years after birth, the ossicular chain is involved in the physiological process of hearing, by which sound waves from the environment are converted into electrochemical impulses. In the last 500 years, most studies have focused on the morphogenesis, morphological variability and clinical pathology of the ossicular chain, whilst only a few studies have added relevant knowledge to anthropology and forensic science. The auditory ossicles and the enclosing petrous bone are some of the hardest in the human skeleton. This is reflected in a relative resistance to fire and in the possibility of preservation and fossilization in millions of years. Materials and Methods: The literature and four present-day forensic cases were included in studying the postmortem loss of the auditory ossicles in skeletal or decomposing remains. Results indicate that it can be ascribed to their destruction or physical displacement, by either macro-micro-faunal action and/or any other natural or artificial disturbance. Discussion: Physical displacement is closely connected to the depositional environment of the skeletal remains, such as burial, entombment (sarcophagus, coffin, vault…), submersion or exposure to natural elements. Auditory ossicles can be recovered in situ, or very close to their anatomical location, when the skeletal material has been involved in an archaeological excavation. In the case of accessible or disturbed remains, scavengers may remove the tiny ossicles and/or they can slip out of the middle ear cavity following skull movements. Entombment offers effective protection against the displacement of the auditory ossicles, whereas aquatic submersion and aquatic movement almost invariably displace them. Conclusion: the preservation of the human auditory ossicles should be critically considered in the comprehensive context of any forensic investigation on human remains since it can assist the reconstruction of their taphonomic history. Taphonomic histories of remains can add crucial information to forensic investigations (e.g., the Post Mortem Interval, PMI). The aim of this study, limited by scarce relevant literature, is to discuss the potential role of the ossicular chain, detected by postmortem imaging techniques, as a taphonomical indicator in decomposing and/or skeletonized bodies.","PeriodicalId":45852,"journal":{"name":"Forensic Sciences Research","volume":"61 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135933527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

McLeod, Mark P. S. Krekeler","doi":"10.3390/forensicsci3040038","DOIUrl":"https://doi.org/10.3390/forensicsci3040038","url":null,"abstract":"Interpersonal violence is a rising issue in global society and new approaches are being sought to combat the problem. Within this context, expanding forensic techniques to better document violent crime scenes is critical for improving and acquiring legal evidence, such as proving or tracing contact between victims and suspects. This project aims to demonstrate the potential for forensic investigations in the context of interpersonal violence using a field-based reflective spectroscopy approach. For this, a common cosmetic, Wet‘N’Wild “Color Icon” blush in the shade “Pearlescent Pink”, was mineralogically characterized using transmission electron microscopy and powder X-ray diffraction and subsequently investigated via reflective spectroscopy on a variety of common substrates. Differing amounts of the cosmetic product, ranging from 0.001 g to 0.075 g, were applied to a variety of substrates using a simple push method to simulate forcible contact and material transfer. Substrates included a pine wood block; (calcareous) sand from Tulum, Mexico; Ottawa sand; tile; Pergo wood; linoleum; closet material; carpets; and fabrics. The reflective spectra of cosmetic–substrate combinations were measured via an ASD FieldSpec 4 Hi-Res spectroradiometer. The Wet‘N’Wild cosmetic was reliably detected on various substrates relevant to crime scenes. Minor amounts (as low as 0.02 mg/mm2) could be detected, and average limits of detection of 0.03 mg/mm2) were achieved; however, a calcareous sand (Tulum) had a high level of detection (&gt;0.38 mg/mm2), suggesting that further investigation is needed for more complex sand substrates. The use of the ASD spectroradiometer as a forensic tool within the context of crime scene documentation shows promise. Future work should expand the characterization of cosmetic materials across a broad range of substrates and consider systematic studies of specific population groups. Furthermore, combining this approach with hyperspectral imaging at crime scenes is a promising future direction for crime scene documentation. This work therefore demonstrates a novel method for investigating cosmetics within the context of interpersonal violence and provides a foundation for future laboratory and field work using the ASD FieldSpec 4 and hyperspectral imaging systems.","PeriodicalId":45852,"journal":{"name":"Forensic Sciences Research","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136032969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are involved in the skin wound healing process with a dynamic expression pattern and can therefore potentially serve as biomarkers for skin wound age estimation. However, no reports have described any miRNAs as suitable reference genes (RGs) for miRNA quantification in wounded skin or samples with postmortem changes. Here, we aimed to identify specific miRNAs as RGs for miRNA quantification to support further studies of skin wound age estimation. Overall, nine miRNAs stably expressed in mouse skin at certain posttraumatic intervals (PTIs) were preselected by next-generation sequencing as candidate RGs. These nine miRNAs and the commonly used reference genes (comRGs: U6, GAPDH, ACTB,18S, 5S, LC-Ogdh) were quantitatively examined using qRT-PCR at different PTIs during skin wound healing in mice. The stabilities of these genes were evaluated using four independent algorithms: GeNorm, NormFinder, Bestkeeper, and comparative Delta Ct. Stability was further evaluated in mice with different postmortem intervals (PMIs). Overall, mmu-miR-26a-5p, mmu-miR-30d-5p, and mmu-miR-152-3p were identified as the most stable genes at both different PTIs and PMIs. These three miRNA RGs were additionally validated and compared with the comRGs in human samples. After assessing using one, two, or three miRNAs in combination for stability at different PTIs, PMIs, or in human samples, the set of miR-26a/30d/152 was approved as the best normalizer. In conclusion, our data suggest that the combination of miR-26a/30d/152 is recommended as the normalization strategy for miRNA qRT-PCR quantification in skin wound age estimation.","PeriodicalId":45852,"journal":{"name":"Forensic Sciences Research","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135759330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
