Morgagni is considered the father of pathological anatomy. He died in 1771, 89 years old, and was buried in Saint Maxim church in Padua, where his wife and five of his 15 children were already buried. In 2011, an anthropological analysis confirmed that one of the skulls belonged to the oldest individuals among those found in Morgagni's tomb. A genetic analysis proved a kinship between this skull and the fragments of young individuals (one male and two females), supporting the hypothesis that they were Morgagni and his children...

Besides assessment of forensic patients' risk of future violence and criminogenic needs, knowledge on their responsivity to treatment is equally important. However, instruments currently used for risk assessment are not sensitive enough for treatment evaluation. Therefore, the Instrument for Forensic Treatment Evaluation (IFTE) was developed. The IFTE is a treatment evaluation tool, which uses the dynamic risk items of the Dutch risk assessment tool, the HKT-R (Historical, Clinical, Future-Revised). The IFTE has an extended answering scale, which makes it more sensitive for measuring change and enables clinicians to monitor patients' responsivity to treatment closely...

RATIONALE: Owing to the widespread abuse of new psychoactive substances (NPSs), developing a rapid, easily operable method to detect NPSs in oral fluid is of high priority. Easy collection and non-invasive nature make oral fluid samples suitable for on-site tests and forensic cases. Herein we report a rapid and sensitive method to screen and quantitate 11 new NPSs in oral fluid. METHOD: A low temperature plasma probe mass spectrometry (LTP-MS) was applied and to improve the signal intensity, thermally assisted desorption was employed...

Liver function tests have been investigated in the forensic setting in several biological fluids collected at autopsy. Nevertheless, the results of these investigations have provided diverging information on postmortem stability of liver function markers and postmortem reliability of liver function assessment. The first aim of this study was to determine gamma-glutamyltransferase, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total bilirubin, total proteins, and albumin in antemortem and postmortem serum samples in a series of cases that underwent forensic investigations and had both samples available...

BACKGROUND: The Forensic medicine reform in 2011 enabled the development of forensic units specialized in multidisciplinary care of victims of criminal offences. Thanks to an annual budgetary allocation, the Ministry of Justice handles the financing of judicial acts, while the health care facilities assume the medical, psychological and social aspects. The objective of this study was to determine the direct costs of medical care provided to rape victims (such as defined in the article 222-23 of the Penal Code) in order to see how its funding could be reconsidered to prevent any additional cost that could be caused by non-sufficient medical, psychological and social care...

The emergence of an increasing number of new psychoactive substances (NPS) on the drug market requires a paradigm shift in drug testing. Immunoassay screening needs to be replaced with highly specific and sensitive analytical methods based on chromatography and mass spectrometry to produce accurate results, promote health and patient safety and collect data on the prevalence of NPS use, impact on public health and clinical aspects of NPS in Denmark. Development and implementation of new analytical methods currently present a major challenge for both clinical and forensic laboratories...

Soil traces are useful as forensic evidences because they frequently adhere to individuals and objects associated with crimes and can place or discard a suspect at/from a crime scene. Soil is a mixture of organic and inorganic components and among them soil clay contains signatures that make it reliable as forensic evidence. In this study, we hypothesized that soils can be forensically distinguished through the analysis of their clay fraction alone, and that samples of the same soil type can be consistently distinguished according to the distance they were collected from each other...

Some of the expected advantages of next generation sequencing (NGS) for short tandem repeat (STR) typing include enhanced mixture detection and genotype resolution via sequence variation among non-homologous alleles of the same length. However, at the same time that NGS methods for forensic DNA typing have advanced in recent years, many caseworking laboratories have implemented or are transitioning to probabilistic genotyping to assist the interpretation of complex autosomal STR typing results. Current probabilistic software programs are designed for length-based data, and were not intended to accommodate sequence strings as the product input...

DNA from biological forensic samples can be highly fragmented and present in limited quantity. When DNA is highly fragmented, conventional PCR based Short Tandem Repeat (STR) analysis may fail as primer binding sites may not be present on a single template molecule. Single Nucleotide Polymorphisms (SNPs) can serve as an alternative type of genetic marker for analysis of degraded samples because the targeted variation is a single base. However, conventional PCR based SNP analysis methods still require intact primer binding sites for target amplification...

The Athlete's Biological Passport (ABP) refers to the collection of data related to an individual athlete. The ABP contains the Haematological Module and the Steroidal Module, which are used for the longitudinal monitoring of variables in blood and urine respectively. Based on changes in these variables, a statistical model detects outliers which indicate doping use and guide further targeted testing of the athlete. Presently, athletes can access their data of the Haematological Module in ADAMS. However, granting athletes access to this data has been a matter of debate within the anti-doping community...

Due to the unique inheritance pattern, X-chromosomal short tandem repeats (X-STRs) have several advantages in complex kinship cases, such as deficiency cases or grandparent-grandchild and half-sisters testing. In our study, 541 unrelated individuals gathered from Mongolian and Eastern Chinese Han populations were successfully genotyped using the Investigator Argus X-12 kit. We calculated allele/haplotype frequencies and other forensic parameters of the two populations and further explored their genetic distance with already published Chinese populations and six global populations...

Personalised medicine promises to provide us with a diagnostic predictive system of stratification that is based on a wide variety of tests; these can include biological, cognitive, demographic, psychopathological tests and other clearly defined tests. The purpose of forensic psychiatry is not only to take care of and treat mentally impaired patients but also to engage in risk assessment and risk management.<br/> AIM: To explain risk assessment in forensic psychiatry as a nomothetic approach to personalised medicine, and also to demonstrate the link with offence paralleling behaviour, which is an illustration of the ideographic approach...

Microbiome analysis of environmental samples may represent the next frontier in environmental microbial forensics. Next-generation sequencing technologies significantly increased the available genetic data that could be used as evidentiary material. It is not clear, however, whether the microbiome can scale across institutions using forensic-based evidence due to the data resource requirements and the associated costs of maintaining these databases. A successful microbiome study is impacted by the quality of the information gathered and the steps in sample processing and data analysis...

Despite the successful application of virtual reality (VR) in a wide variety of mental disorders and the obvious potentials that VR provides, the use of VR in the context of criminology and forensic psychology is sparse. For forensic mental health professionals, VR provides some advantages that outrun general advantages of VR, e.g., ecological validity and controllability of social situations. Most important seems to be the unique possibility to expose offenders and to train coping skills in virtual situations, which are able to elicit disorder-relevant behavior-without endangering others...
