Current status of undergraduate teaching in forensic & legal medicine in Europe.

The European Council of Legal Medicine (ECLM) is the body established in 1992 to represent practitioners forensic & legal medicine and is composed of delegates of the countries of the European Union (EU) and from other countries which form part of Europe to a current total of 34 member countries. The aims of this study were to determine the current status of undergraduate forensic & legal medicine teaching in the curriculum of medical studies in ECLM countries and to use the results of this study to determine whether it would be appropriate to develop new guidelines and standards for harmonising the content of undergraduate forensic medicine training across ECLM member countries. A detailed questionnaire was sent to all individuals or organisations listed on the ECLM contact database. Responses were received from 21 of 33 countries on the database. These responses showed considerable emphasis on undergraduate teaching of forensic medicine in all countries with the exception of Belgium and the United Kingdom. There was great general consistency in the subjects taught. The data from this survey provide a baseline which should assist in developing a strategy to harmonise forensic & legal medicine undergraduate training in member countries of the ECLM. The ECLM is now in a good position to establish a pan-European working group to coordinate a consensus document identifying an appropriate and modern core undergraduate forensic medicine curriculum that can be presented to the medical education authorities in each country, and which can be adapted for local requirements, based on available personnel, the forensic medicine structure in the country, and most importantly, the needs of the local population.

The forensic imaging technique of age progression used within missing people cases: The Italian Missing Children association realizing age progression for Missing Child Kenya.

The age progression technique allows to update identification photos of individuals who have been missing for years. This method is based on the study of the facial variation and on the dynamics of facial growth. Knowledge about changes in the distribution of facial fat and the tone of the cartilage allows realistic predictions of the facial appearance after many years. Beside these elements, age progression is also supported by similar characters between family members. This is why photos of the missing and family members are used to create an age progression, making the new identikit accurate. Non-profit associations are crucial for the dissemination of information on the problem of missing persons. In Italy, the Italian Missing Children association provides for free an age progression service with the support of forensic anthropology. With the activation of a protocol, consisting of guidelines, and a form for the request for age progression by family members, the Italian Missing Children has started a collaboration with Missing Child Kenya. It allowed to disseminate up-to-date photos of the presumed current appearance of the missing children in Kenya. Thus, in the present study some cases are reported, in which age progression technique was applied. The photos provided by Italian Missing Children were shown in video documentaries made by Missing Child Kenya, allowing to continue the dissemination of age progression photo during the Covid quarantines and to keep the population active in the search for the missing.

Taxonomic and metabolic development of the human gut microbiome across life stages: a worldwide metagenomic investigation.

The human gut microbiota is a dynamic community of microorganisms that undergo variable changes over the entire life span. To thoroughly investigate the possible fluctuations of the microbiota throughout human life, we performed a pooled analysis of healthy fecal samples across different age groups covering the entire human life span. Our study integrated data from 79 publicly available studies and new stool samples from an Italian cohort, i.e., the Parma Microbiota project, resulting in 6,653 samples processed through the shotgun metagenomic approach. This approach has allowed species-level taxonomic reconstruction of the gut microbiota and investigation of its metabolic potential across the human life span. From a taxonomic point of view, our findings confirmed and detailed at species-level accuracy that the microbial richness of the gut microbiota gradually increases in the first stage of life, becoming relatively stable during adolescence. Moreover, the analysis identified the potential core microbiota representative of distinct age groups, revealing age-related bacterial patterns and the continuous rearrangement of the microbiota in terms of relative abundances across the life span rather than the acquisition and loss of taxa. Furthermore, the shotgun approach provided insights into the functional contribution of the human gut microbiome. The metagenomic analysis revealed functional age-related differences, particularly in carbohydrate and fiber metabolism, suggesting a co-evolution of the microbiome assembly with diet. Additionally, we identified correlations between vitamin synthesis, such as thiamine and niacin, and early life, suggesting a potential role of the microbiome in human physiology, in particular in the functions of the host's nervous and immune systems. IMPORTANCE: In this study, we provided comprehensive insights into the dynamic nature of the human gut microbiota across the human life span. In detail, we analyzed a large data set based on a shotgun metagenomic approach, combining public data sets and new samples from the Parma Microbiota project and obtaining a detailed overview of the possible relationship between gut microbiota development and aging. Our findings confirmed the main stages in microbial richness development and revealed specific core microbiota associated with different age stages. Moreover, the shotgun metagenomic approach allowed the disentangling of the functional changes in the microbiome across the human life span, particularly in diet-related metabolism, which is probably correlated to bacterial co-evolution with dietary habits. Notably, our study also uncovered positive correlations with vitamin synthesis in early life, suggesting a possible impact of the microbiota on human physiology.

Father figure: Study of the age progression process from old pictures and its value in forensic sciences.

The application of age progression to the search for missing persons demonstrates its usefulness in being able to reconstruct the aged face based on the current age of a person who has been missing for many years. Age progression takes into account facial physiognomic elements and their changes over time. Based on these premises, the present study aims to investigate the evolution of somatic features, from childhood to adulthood, of one of the authors' father using photos at different ages of him. Sixteen photos were collected depicting an individual of Italian origin between the age of 1 and 72. The photos were processed in Adobe© Photoshop software to graphically highlight the shape development of individual physiognomic elements. The shape of the face, eyebrows, eyes, nose, mouth, and cheeks were analysed in detail using a morphological approach. The ageing processes that occurred in this case were discussed on the basis of the literature. The present study demonstrates the in-depth analysis of the dynamics of facial growth in a single case. Nonetheless, aging is different for each individual, so further studies are necessary to observe facial development on as many subjects as possible.

Epigenetic analyses in forensic medicine: future and challenges.

The possibility of using epigenetics in forensic investigation has gradually risen over the last few years. Epigenetic changes with their dynamic nature can either be inherited or accumulated throughout a lifetime and be reversible, prompting investigation of their use across various fields. In forensic sciences, multiple applications have been proposed, such as the discrimination of monozygotic twins, identifying the source of a biological trace left at a crime scene, age prediction, determination of body fluids and tissues, human behavior association, wound healing progression, and determination of the post-mortem interval (PMI). Despite all these applications, not all the studies considered the impact of PMI and post-sampling effects on the epigenetic modifications and the tissue-specificity of the epigenetic marks.This review aims to highlight the substantial forensic significance that epigenetics could support in various forensic investigations. First, basic concepts in epigenetics, describing the main epigenetic modifications and their functions, in particular, DNA methylation, histone modifications, and non-coding RNA, with a particular focus on forensic applications, were covered. For each epigenetic marker, post-mortem stability and tissue-specificity, factors that should be carefully considered in the study of epigenetic biomarkers in the forensic context, have been discussed. The advantages and limitations of using post-mortem tissues have been also addressed, proposing directions for these innovative strategies to analyze forensic specimens.

Artificial intelligence in healthcare: why not apply the medico-legal method starting with the Collingridge dilemma?

Technology has greatly influenced and radically changed human life, from communication to creativity and from productivity to entertainment. The authors, starting from considerations concerning the implementation of new technologies with a strong impact on people's everyday lives, take up Collingridge's dilemma and relate it to the application of AI in healthcare. Collingridge's dilemma is an ethical and epistemological problem concerning the relationship between technology and society which involves two approaches. The proactive approach and socio-technological experimentation taken into account in the dilemma are discussed, the former taking health technology assessment (HTA) processes as a reference and the latter the AI studies conducted so far. As a possible prevention of the critical issues raised, the use of the medico-legal method is proposed, which classically lies between the prevention of possible adverse events and the reconstruction of how these occurred.The authors believe that this methodology, adopted as a European guideline in the medico-legal field for the assessment of medical liability, can be adapted to AI applied to the healthcare scenario and used for the assessment of liability issues. The topic deserves further investigation and will certainly be taken into consideration as a possible key to future scenarios.

Drug-facilitated sexual assault followed by femicidal chloroform poisoning and suffocation: A case-report of criminal responsibility.

INTRODUCTION: Criminal responsibility evaluation represents one of the most controversial and debated issues in forensic psychiatry. Although clear procedures have been recommended, little research exists on decision-making process by forensic psychiatrists. We present a case assessing the criminal responsibility of a murderer who committed femicide as a result of chloroform poisoning and suffocation after a drug-facilitated sexual assault. MATERIALS AND METHODS: A.S., a 30-year-old female, was found dead in the home of S.P., a 50-year-old male. S.P. recounted killing A.S. by forced inhalation of chloroform, when the woman had experienced sensory clouding following unintentional ingestion of Zolpidem, a hypnotic agent. A multidisciplinary approach was taken to resolve the case. Autopsy, histological, genetic, and toxicological examinations were performed by a forensic pathologist, while a digital forensic examiner analysed electronic devices. A pool of three forensic psychiatrists and two psychologists was asked to assess the mental state of S.P. at the time of the crime. RESULTS AND CONCLUSIONS: The cause of death of A.S. was identified as a lethal chloroform intoxication in altered consciousness caused by Zolpidem, while homicidal suffocation was also described. Mobile forensics demonstrated that S.P. had videotaped the crime scene, clearly revealing that A.S. had been sexually assaulted by S.P. before dying. Criminal responsibility of S.P. was evaluated through various psychological tests and seven interviews with the accused, each lasting an average of 180 min. Specialists concluded that S.P. could not be exempted from being responsible for the homicide.

Unveiling the Dark Nexus: A systematic review on the interplay of mental health, substance abuse, and socio-cultural factors in femicide.

A shared definition of femicide would help to distinguish it from the murder of a woman and understand its root causes favoring prevention. We conducted a Systematic Literature Review (SLR) to assess how (and if) femicide cases were related to mental disorders. Articles papers that explicitly define or discuss femicides or articles that, albeit not expressly mention femicides, thoroughly compare generic homicides and homicides with female victims. We analyse 3546 articles were retrieved from the databases, and 75 studies fulfilled the eligibility criteria and were included in the SLR. Many forms of femicide emerge worldwide as people's values, beliefs, attitudes, and behaviours evolve (intimate partner femicide, femicide-suicide, religious femicide, honour, revolt femicide) and state of vulnerability. A tiny percentage of femicides occur at the hands of subjects with diagnosed mental disorders, and controversies exist regarding the possible link between femicide and the use of drugs and/or alcohol and other factors. The complex problem of violence against women must be addressed with a transdisciplinary approach and targeted interventions for both the victims and the perpetrators. The present SLR shows that it is not possible to link femicides to mental disorders and that socio and cultural factors appear to be more relevant. Further quantitative research is warranted to disentangle the root causes of this heinous phenomenon plaguing our times. Our studies show that using the proposed definition of feminicide would help to delimit and adequately recognise violence in courtrooms, promote the culture of equality, and identify adequate policy strategies for prevention.

Medically assisted suicide in Italy: Recent legal developments on a controversial topic.

On 16th June 2022, the first case of lawful 'medically assisted suicide' took place on Italian soil. This event is a result of decade-long debates on informed consent and end-of-life care stimulated by medical jurisprudence. The authors first retrace the crucial moments that allowed this to happen and underline the problems still to be solved. The cases of DJ Fabo, Davide Trentin, Mario and Fabio Ridolfi are discussed, signalling how they influenced the path implemented by Italian jurisprudence.

Determination of ethyl glucuronide in hair and self-reported alcohol consumption in university students.

Young individuals constitute an intriguing population, as their drinking habits are notably shaped by their perception of their peers' alcohol consumption. Nonetheless, excessive alcohol intake can have detrimental effects on academic performance, interpersonal relationships, and the risk and severity of accidents. This study reported the first data involving students enrolled from three universities on a voluntary basis for alcohol consumption evaluation. Alcohol consumption was assessed through questionnaires and EtG quantification in hair (hEtG) carried out by liquid chromatography-mass spectrometry (LC-MS/MS) analysis after a solid-phase extraction (SPE) purification step. The results of our study demonstrated that 77.1% of samples tested negative for hEtG or displayed hEtG ≤ 5 pg/mg. Particularly, the student population was not characterized by samples with hEtG indicative of chronic excessive consumption (hEtG ≥ 30 pg/mg). No significant association was identified between biological sex, among the degree course/the year attended, nor in relation to BMI or smoking/coffee consumption. Among the obtained results, it was worth noting that the comparison of self-reporting abstinence from tobacco and coffee accounted for 65.3% and 16.7%, respectively, while only 2.8% of the total declared abstinence from alcohol. The current study has uncovered a significant level of interest among students in this analysis and its interpretation. This suggests that implementing public health promotion activities within a university setting could be beneficial.

On-Site Inspection Form in Veterinary Cases: The Parma Veterinary Form.

The on-site inspection of the scene of an animal cadaver is crucial for a correct interpretation of the autopsy results, to determine the manner, method, and cause of death. This information plays a crucial role in the control of public health including the prevention of zoonoses. It is also fundamental for the recognition and the contrast of crimes against animals and to animal abuse phenomena, considered an alert sign of an anti-social or violent behavior of humans. Today the best veterinary procedure requires an accurate collection of the evidence at the scene that can be then handed to experts belonging to other forensic disciplines for further evaluation and data interpretation. In this paper authors suggest a form aiming to facilitate either the on-site and the autopsy activities, as a guarantee of the quality of the forensic process starting from the discovery scene up to the reconstruction of the case. Essential is training of non-medical personnel who often represent the first responder to be present on the scene. The form is inspired by the interdisciplinary form developed by the European Council of Legal Medicine and represents an initial tool to stimulate a multidisciplinary activity in close synergy with other forensic experts.

Education nursing students' in Palliative Care and Pain Therapy: an observational study.

BACKGROUND AND AIM: University education plays an important role in the preparation of future nurses, especially in the care of dying patients, which is one of the most emotionally engaging aspects. The objectives of the study were to describe the attitudes of students in end-of-life care and to analyze the possible relationship with some socio-demographic variables, through an observational study. METHODS: Preliminarily, an analysis of the educational context of the Nursing Course  of the University of Parma was started, through a comparison of the university course with the recommendations of the MIUR concerning the teaching and learning of Palliative Care and Pain Therapy. Subsequently, a questionnaire containing the Frommelt Attitude Toward Care of the Dying Scale Form B and some socio-demographic context variables was administered to a sample of 109 students belonging to the CoS of Nursing in Parma. RESULTS: From the data collected, it emerged that university planning partly reflects the recommendations of the MIUR and how, on average, nursing students have described positive attitudes in all the dimensions investigated. Interesting is the presence of a positive relationship between the personal experiences of bereavement and the attitudes of the students. CONCLUSIONS: Nurses are essential in ensuring the quality of care provided to patients at the end of life; Nursing training in Palliative Care and Pain Therapy should include a complete and varied program (frontal activity, simulation, internship paths...) in order to develop positive student attitudes associated with high levels of satisfaction and improvement of the quality of care provided.

Femicide and forensic pathology: Proposal for a shared medico-legal methodology.

In a previous work, authors have proposed a medico-legal definition of femicide as the murder due to the failure to recognize the right of self-determination of women. The aim of this paper was to apply the proposed definition to a cohort of cases to characterise femicides and female homicides and assess whether femicides can be considered a distinct entity or not. A comparison between female and male homicides was performed to assess common and distinctive features. Femicides were identified and compared to the cohort of non-femicide female murder. Results were compared to those reported in published forensic studies. Significant associations between female and male homicides were found for sex and partner/ex-partner offender, sex and indoor homicide and sex and asphyxia as dynamic of death emerged. A higher prevalence of indoor homicides and asphyxiation and of partner relationships were documented in female homicides. Gunshot, blunt injuries and cut wounds are well represented in both types of homicides. Most affected sites are back and chest in male homicides, and head, breasts, pubis, and limbs in female homicides. When comparing femicides and female homicides, a positive association between strangulation as harmful mean and a negative one between femicides and indoor homicides were found. Male and female homicides can be considered as two distinct victimological phenomena. Focusing on femicide allows to establish injuries and circumstantial patterns, that could represent evidence of a specific murder. More studies with a standardized data collection are needed to corroborate the theory of this paper.

Over 30-year retrospective analyses of moped-motorcycle fatal road accidents in the northern area of the Italian region of Emilia Romagna and review of the literature: Aiming for further preventive measures in the future.

Road traffic injuries are a major cause of morbidity and mortality worldwide, with pedestrians and riders of two-wheeled motor vehicles being the most vulnerable. The present study aims to determine the epidemiological characteristics of fatal motorcycle crashes in a portion of the Italian region of Emilia Romagna, and to compare them with the data available in literature. Data were retrieved from autopsy reports on 350 subjects who died following road accidents involving moped or motorcycle in the cities of Parma, Piacenza, and Reggio Emilia. Two types of data were extrapolated: circumstantial and traumatological. The population was divided into subgroups according to gender, crash time, alcohol positivity, presence or absence of the helmet, and the period elapsed between the accident and death. Most of the considered road accidents occurred during the day and on weekends. 25.5 % of the victims tested positive for alcohol. As far as traumas are concerned, the limbs resulted to be the most affected body segment, followed by the head (87.4 %), the thorax (85.7 %), the abdomen (65.7 %), and lastly the neck (50.3 %). According to similar studies, the sample victim of a moped/ motorcycle accident is a young male subject. The results obtained allow us to demonstrate that the mandatory use of the helmet has reduced skull and brain injury over the years. At present, no law regulates the use of protections for other body parts. Regulatory interventions in this sense would be desirable given the ever more rapid technical evolutions in the field of motorcycles.

Oral fluid analysis to monitor recent exposure to synthetic cannabinoids in a high-risk subpopulation.

Among novel psychoactive substances, synthetic cannabinoid receptor agonists (SCRA) seem to have the widest diffusion in the population with no limitation to any particular demographic group. Information on drug consumption relies mostly on anonymized surveys and less on clinical or analytical data; notwithstanding, the huge efforts constantly made to enroll subjects to gather epidemiological data. In the present study, we collected 66 oral fluid samples from volunteers in a drug rehabilitation center in 2019 and early 2020. A liquid chromatography-mass spectrometry method previously developed and validated by our Unit was applied to detect SCRA (n = 10) in oral fluid. Results proved the presence of synthetic cannabinoids at a positivity rate of almost 20%, with detection frequency HU211(5/13) > UR144/JWH122 (3/13) > JWH019/JWH081/AM2201 (1/13). Concentrations were in the range < LOQ -0.36 ng/ml. Synthetic cannabinoids consumption had not been declared by any volunteer. This study enabled for the unprecedent detection of synthetic cannabinoids use in the territory of Parma (Italy) in a high-risk subpopulation. The identified SCRA proved the persistence into the market of the "first-generation" JWH family into the Italian territory and the marketing of relatively new ones (AM-2201). Public health consequences represented by NPS consumption are still scarce; therefore, further studies are needed to understand the real diffusion in the population.

Third trimester intrauterine fetal death: proposal for the assessment of the chronology of umbilical cord and placental thrombosis.

The timing of umbilical cord and placental thrombosis in the third trimester intrauterine fetal death (TT-IUFD) may be fundamental for medico-legal purposes, when it undergoes medical litigation due to the absence of risk factors. Authors apply to human TT-IUFD cases a protocol, which includes histochemistry and immunohistochemistry (IHC) for the assessment of thrombi's chronology. A total of 35 thrombi of umbilical cord and/or placenta were assessed: 2 in umbilical artery, 6 in umbilical vein, 15 in insertion, 10 in chorionic vessels, 1 in fetal renal vein, 1 in fetal brachiocephalic vein. Thrombi's features were evaluated with hematoxylin-eosin, Picro-Mallory, Von Kossa, Perls, and immunohistochemistry for CD15, CD68, CD31, CD61, and Smooth Muscle Actin. The estimation of the age of the thrombi was established by applying neutrophils/macrophages ratio taking into consideration, according to literature, the presence of hemosiderophagi, calcium deposition, and angiogenesis. To estimate an approximate age of fresh thrombi (< 1 day), a non-linear regression model was tested. Results were compared to maternal risk factors, fetal time of death estimated at autopsy, mechanism, and cause of death. Our study confirms that the maternal risk factors for fetal intrauterine death and the pathologies of the cord, followed by those of the placental parenchyma, are the conditions that are most frequently associated with the presence of thrombi. Results obtained with histological stainings document that the neutrophile/macrophage ratio is a useful tool for determining placental thrombi's age. Age estimation of thrombi on the first day is very challenging; therefore, the study presented suggests the N/M ratio as a parameter to be used, together with others, i.e., hemosiderophagi, calcium deposition, and angiogenesis, for thrombi's age determination, and hypothesizes that its usefulness regards particularly the first days when all other parameters are negative.

Oral status of a noble European couple from the 16th century: A morphologic analysis of the teeth of Alessandro Farnese and his wife Maria D'Aviz.

Objective. To report the results of dental morphological analysis performed on the remains of two European nobles (Duke Alessandro Farnese and his wife Maria D'Aviz) who lived in the 16th century, together with hypotheses on their nutrition and oral hygiene habits. Design and results. The remains of Alessandro Farnese (1545-1592) and Princess Maria D'Aviz (1538-1577) were exhumed in Parma, Italy, in the context of an historical investigation into their possible causes of death. The skulls were examined and analysed through direct inspection, high-detailed photographs and radiographs. Ante mortem tooth loss (AMTL), postmortem tooth loss (PMTL), Scott and Smith dental wear indexes and the Kerr periodontal index were used to assess the dental and periodontal status of the couple. Alessandro Farnese suffered from severe dental wear while it was presumed that Maria D'Aviz was affected by periodontal disease and tooth decay. Conclusions. Based on the findings of the present analysis, we hypothesise that Alessandro Farnese's diet was mainly based on hard and unrefined foods, also suggested by limited historical reports. It is likely that Maria D'Aviz's nutrition was based on sugar-enriched foods.
