We conducted a literature search of six bibliographic databases up to March 2024. Additional searches were performed using citation tracing strategies. Nineteen studies published between 1991 and 2023 were retained. Most were published between 1991 and 2000, mainly in the USA. A scientific gap was observed for 10 years before studies resumed between 2011 and 2022. These 19 studies involved 2931 children; most were girls (<i>n</i> = 2080; 71%). The mean age was 9.4 years (SD = 2.40; min = 2; max = 17.5). Most studies did not mention the nature of the relationship between the child and the alleged perpetrator of sexual violence, three studies involved intra-family violence and six studies involved victims of intra- and extra-family violence. Nearly 75% of the interviewers were trained with SVA methods. Most were mental health professionals (52.6%) or police officers (15.8%). No study used the SVA as a whole, 10 studies used 19 criteria of the Criteria-Based Content Analysis (CBCA), and no study used the Validity Check List (VCL). Most studies performed SVA on interview transcripts (<i>n</i> = 8), and two studies performed their analysis on both verbatims and video. The conclusion of our literature review highlights the methodological weaknesses of these studies and encourages more research about the use of SVA in the judicial field to reduce the risk of misleading the judiciary.</p>","PeriodicalId":15743,"journal":{"name":"Journal of forensic sciences","volume":"69 6","pages":"1948-1958"},"PeriodicalIF":1.5,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1556-4029.15604","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142038052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A statistical characterization of these automated approaches was performed using four datasets of consecutively manufactured firearms to provide a challenging comparison scenario. Each automated approach was applied to all samples in a pairwise fashion, and classification performance was compared. Based on these findings, a Bayesian network was empirically learned and constructed to leverage the strengths of each individual approach, model the relationship between the automated results, and combine them into a posterior probability for the given comparison. The network was evaluated similarly to the automated approaches, and the results were compared. The developed Bayesian network classified 99.6% of the samples correctly, and the resultant probability distributions were significantly separated more so than the automated approaches when used in isolation.</p>","PeriodicalId":15743,"journal":{"name":"Journal of forensic sciences","volume":"69 6","pages":"2028-2040"},"PeriodicalIF":1.5,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142038051","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}

Yet, challenges persist regarding complex sample processing and assurance of equal molar concentrations across pooled samples. Since optimal cluster density is crucial for sequencing performance, the determination of both quantity and quality is indispensable for library preparation. In this study, we investigated the application of the Agilent 2100 Bioanalyzer for library quality control, as studies for forensic approaches, particularly for highly degraded postmortem samples, are rare. Our analysis encompassed assessing total DNA concentrations, fluorescence unit (FU) values, and adapter dimer concentrations in purified DNA libraries derived from buccal swabs and tissue samples of decomposed corpses. The sensitivity study tested a serial dilution derived from buccal swabs and revealed a decrease in FU values and an increase in adapter dimers with declining DNA input concentrations. Deviations in total DNA concentrations and average peak heights between the Agilent 2100 Bioanalyzer runs indicated a lack of repeatability in data and presented challenges in accurate quantification, which was also observed in previous studies. Yet, the analysis of degraded samples from decomposed human remains has shown the ability to detect adapter dimer concentrations, which can be crucial for the quality of subsequent NGS library preparation and sequencing success. Therefore, the Agilent 2100 Bioanalyzer proves to be a valuable tool for NGS quality control.</p>","PeriodicalId":15743,"journal":{"name":"Journal of forensic sciences","volume":"69 6","pages":"2192-2196"},"PeriodicalIF":1.5,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1556-4029.15601","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142019922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We agree with the authors that the identification of injuries in patients who have experienced physical violence is important. As colleagues who are forensic medicine experts, we recognize the importance of visualizing bruises in cases of interpersonal violence, especially in individuals with darkly pigmented skin, so we applaud your research on this issue. Practitioners need to be as accurate as possible in their evaluation. The use of tools to assist in the identification of injuries can be very helpful. We also recognize that forensic sciences and the associated analysis or evaluation must remain accurate and valid and not utilize “presumptive tests without confirmation” or tests lacking “reliability, reproducibility, repeatability, and replicability” [&lt;span&gt;2, 3&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;When reading this article, we were struck by the remarkable similarity in methods with previous publications by these authors on this topic [&lt;span&gt;4, 5&lt;/span&gt;]. All three studies have the same number of 157 participants. This study and the study published in 2020 describe the same methodology of “quota sampling” to “recruit equal numbers of healthy participants.” The study published in 2022, however, stated that “a convenience sample of 157 subjects” was obtained. If these studies are of the same participants, then the statement in the 2022 publication about how the participants were recruited appears to be incorrect and potentially misleading. We are concerned that multiple studies analyzing the same data set create an improper opportunity for bias and post hoc analysis error.&lt;/p&gt;&lt;p&gt;The authors found in a previous analysis of the participants that both the 415 nm ALS with a yellow filter and the 450 nm ALS with a yellow filter to be “optimal for detecting evidence of bruising on individuals with known trauma” [&lt;span&gt;5&lt;/span&gt;]. This was also apparent from table 5 of their 2020 study with the same data [&lt;span&gt;4&lt;/span&gt;].
