Characteristics of suicides of young people in Porto Alegre, Southern Brazil, from 2010 to 2016.

The purpose of this study was to describe demographic, toxicological, criminal, and medicolegal characteristics of suicides of young people aged up to 24 years examined by the Porto Alegre Medicolegal Office, from 2010 to 2016. This cross-sectional study collected data from the Porto Alegre Medicolegal Office and the Rio Grande do Sul State Police Department. The information was obtained from death certificates, toxicological analyses and police reports. Rates were calculated according to sex and age range (under 15 years old, 15 to 19 years old, and 20 to 24 years old) for comparing local with national data. There were 143 people who died by suicide in the period, 120 males and 23 females. Hanging was the most frequently used method, but in the range of 10 to 14 years old, firearm use was the predominant method. Fifty percent of male victims and 30% of female victims had some criminal history. Suicide rates in the study groups generally followed national trends. The relative frequency of suicide by firearm in this study diverged from international findings, as it was relatively more frequent in children under 15 years old and less frequent in older ranges. If confirmed, the finding draws attention to access to firearms in this age range. In older age ranges, adolescents and young adults were frequently involved in the criminal system. This finding may be useful for planning interventions involving both mental health education and screening for problems that may be associated with criminal involvement.

Gender-related and non-gender-related female homicide in Porto Alegre, Brazil, from 2010 to 2016.

Female homicide is a global phenomenon with a higher prevalence in countries in Asia, Africa, and the Americas. Life expectancy in Brazil is compromised by the high risk of death from male and female homicides, a growing social problem. This study aimed to integrate different public datasets and describe the sociodemographic, criminal, and medicolegal characteristics of the homicides of girls and women occurring in Porto Alegre, southern Brazil, from 2010 to 2016. The data were obtained from autopsy reports, police reports, and records from crime scenes. During this period, there was a significant increase in overall standardized rates of female homicides (4.98 to 10.85), with a pronounced increase in non-gender-related deaths, especially due to urban violence, such as involvement in drug trafficking and other crimes and robbery resulting in death. Young (15-29 years of age), non-White women were the most affected. Increased female homicide rates due to non-gender-related factors is a new and worrying phenomenon in Brazil. Obtaining specific data on the profile of victims and characteristics of violence is a crucial step in facing the problem and directing public policies.

A qualitative study exploring the process of postmortem brain tissue donation after suicide.

Access to postmortem brain tissue can be valuable in refining knowledge on the pathophysiology and genetics of neuropsychiatric disorders. Obtaining postmortem consent for the donation after death by suicide can be difficult, as families may be overwhelmed by a violent and unexpected death. Examining the process of brain donation can inform on how the request can best be conducted. This is a qualitative study with in-depth interviews with forty-one people that were asked to consider brain donation-32 who had consented to donation and 9 who refused it. Data collection and analyses were carried out according to grounded theory. Five key themes emerged from data analysis: the context of the families, the invitation to talk to the research team, the experience with the request protocol, the participants' assessment of the experience, and their participation in the study as an opportunity to heal. The participants indicated that a brain donation request that is respectful and tactful can be made without adding to the family distress brought on by suicide and pondering brain donation was seen as an opportunity to transform the meaning of the death and invest it with a modicum of solace for being able to contribute to research.

3D forensic facial approximation: Implementation protocol in a forensic activity.

The primary objective of this paper is to report on the successful implementation of forensic facial approximation in a real case in the forensic context. A three-dimensional (3D) facial approximation protocol of the skull was performed with free software, applying techniques in a virtual environment that have already been consolidated in the literature. The skull was scanned with the photogrammetry technique, the digital replica was imported in the Blender software (Blender Foundation, Amsterdam) and individualized model sketches of the face were traced with the MakeHuman software (MakeHuman Org) according to the anthropological profile of the victim. The face created was imported in Blender, where it was adapted, modeled, and sculpted on the 3D skull and its soft tissue markers, using an American open-source application of the technique in the digital environment. The face created in a virtual environment was recognized and legal identification procedures were started, resulting in the more agile delivery of the disappeared body to its next of kin. It is therefore concluded that facial approximation may not be a primary method of human identification, but it can be satisfactorily applied in the forensic field as an individual recognition resource. It has great value in narrowing the search, reducing the number of alleged victims, and leading to identification tests, therefore significantly reducing the number of genetic DNA (deoxyribonucleic acid) tests-which are considered costly for the State or Federation-and consequently reducing the waiting time before delivery of the body to its family.
