Artificial intelligence (AI) in medicine is an increasingly studied and widespread phenomenon, applied in multiple clinical settings. Alongside its many potential advantages, such as easing clinicians’ workload and improving diagnostic accuracy, the use of AI raises ethical and legal concerns, to which there is still no unanimous response. A systematic literature review on medical professional liability related to the use of AI-based diagnostic algorithms was conducted using the public electronic database PubMed selecting studies published from 2020 to 2023. The systematic review was performed according to 2020 PRISMA guidelines. The literature review highlights how the issue of liability in case of AI-related error and patient’s damage has received growing attention in recent years. The application of AI and diagnostic algorithm moreover raises questions about the risks of using unrepresentative populations during the development and about the completeness of information given to the patient. Concerns about the impact on the fiduciary relationship between physician and patient and on the subject of empathy have also been raised. The use of AI in medical field and the application of diagnostic algorithms introduced a revolution in the doctor–patient relationship resulting in multiple possible medico-legal consequences. The regulatory framework on medical liability when AI is applied is therefore inadequate and requires urgent intervention, as there is no single and specific regulation governing the liability of various parties involved in the AI supply chain, nor on end-users. Greater attention should be paid to inherent risk in AI and the consequent need for regulations regarding product safety as well as the maintenance of minimum safety standards through appropriate updates.

The determination of the post-mortal interval (PMI) is an extremely discussed topic in the literature and of deep forensic interest, for which various types of methods have been proposed. The aim of the manuscript is to provide a review of the studies on the post-mortem DNA degradation used for estimating PMI. This review has been performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the PRISMA Guidelines. Several analytical techniques have been proposed to analyse the post-mortem DNA degradation in order to use it to estimate the PMI. Studies focused mainly on animal models and on particular tissues. The results have been mixed: while on the one hand literature data in this field have confirmed that in the post-mortem several degradation processes involve nucleic acids, on the other hand some fundamental aspects are still little explored: the influence of ante and post-mortem factors on DNA degradation, the feasibility and applicability of a multiparametric mathematical model that takes into account DNA degradation and the definition of one or more target organs in order to standardize the results on human cases under standard conditions.

Collection and interpretation of “touch DNA” from crime scenes represent crucial steps during criminal investigations, with clear consequences in courtrooms. Although the main aspects of this type of evidence have been extensively studied, some controversial issues remain. For instance, there is no conclusive evidence indicating which sampling method results in the highest rate of biological material recovery. Thus, this study aimed to describe the actual considerations on touch DNA and to compare three different sampling procedures, which were “single-swab”, “double-swab”, and “other methods” (i.e., cutting out, adhesive tape, FTA^® paper scraping), based on the experimental results published in the recent literature. The data analysis performed shows the higher efficiency of the single-swab method in DNA recovery in a wide variety of experimental settings. On the contrary, the double-swab technique and other methods do not seem to improve recovery rates. Despite the apparent discrepancy with previous research, these results underline certain limitations inherent to the sampling procedures investigated. The application of this information to forensic investigations and laboratories could improve operative standard procedures and enhance this almost fundamental investigative tool’s probative value.

In Western countries, a social trend toward delaying childbearing has been observed in women of reproductive age for the last two decades. This delay is due to different factors related to lifestyle, such as the development of a professional career or the absence of the right partner. As a consequence, women who defer childbearing may find themselves affected by age-related infertility when they decide to conceive. Fertility preservation techniques are, therefore, proposed as a solution for these women. Among all possible solutions, social freezing is an alternative strongly discussed from a scientific, social and ethical point of view. A survey among 930 female students at the University of Padova (Italy) investigated their knowledge and attitudes on social egg freezing and their potential intentions regarding this procedure. To our knowledge, this is the first study to examine the level of awareness of age-related infertility in Italian young women and their attitudes regarding acceptable indications for elective oocyte freezing, their potential personal use, the circumstances in which they would then decide to use cryopreserved eggs, and their attitudes towards cost coverage and oocyte donation. Data collected in this study revealed some important points about young women and their knowledge about social oocyte freezing in Italy as compared to other European countries and the United States. Overall, 34.3% of the students reported having heard about the possibility of oocyte cryopreservation for non-medical reasons and being aware of the meaning of this procedure; only 19.5% were in favour of social egg freezing and 48.4% thought that the cost for this procedure should be borne entirely by the woman herself. Regarding egg donation, the majority of students (64.9%) would not accept donating their eggs to a known woman or couple and 42.5% would instead accept donating to a biobank. Our study shows that young Italian women are significantly less aware of age-related decline in fertility and the possibility of using social egg freezing compared to their similarly situated counterparts in other Western countries.

Cyberbullying can be described as a form of bullying carried out by an individual or a group through digital media with the intention to harm others. It has been recognized as a public health issue recently; however, of the vast literature published in recent years on the phenomenon, only a small part concerns strategies adopted to prevent and combat cyberbullying, and the effectiveness of these strategies appears to be scarce. We conducted a systematic review of the literature published in the last five years about different interventions studied to prevent and contrast cyberbullying. Our results show how most of the strategies currently developed focus on the educational aspect, involving schools and families. Other authors describe technology-based practices to set programs to reduce and prevent cyberbullying through the usage of digital instruments, the same used by minors themselves. Finally, remaining tactics use a more comprehensive approach, mixing tools already in use in the aforementioned strategies. Cyberbullying requires wide-ranging methods to combat it, involving the contribution of mental health professionals, educators, and digital experts cooperating synergically. Prevention and contrast instruments should be defined, implemented, tested, and combined in order to deal with cyberbullying.
