Introduction. The autolytic attempt is caused by a psychological-emotional destabilization of the person, who deliberately generates violence on himself and commits the act through various means without resulting in death, but with serious injuries and has a high possibility of becoming a suicide. Objective. To analyze the risk factors and causes associated with self-inflicted attempts, as well as suicidal behaviors, through a systematic literature review. Methodology. For this study, a bibliographic review was developed in databases such as: SciELO, Regional Portal of the Virtual Health Library, Scopus, PubMed, ProQuest, Dialnet and Redalyc, using Google Scholar and search engines in the selection of articles. Results. The authors agree that self-harming behaviors are influenced by personal, interpersonal, socioeconomic, cultural, and psychiatric factors, present at all stages of life, but more common in adolescence and adulthood. Risk factors include age, marital status, family dysfunction, substance abuse, and socioeconomic problems, among others. Biological, psychiatric, and emotional causes, such as personality disorders and depression, stand out for their high lethality. Therefore, it is essential that nursing professionals are trained to recognize and address these risk factors, focusing on prevention and timely intervention. Conclusion. The identification of multifactorial risk factors for self-injurious behavior underscores the complexity and severity of the problem, especially in vulnerable populations. The training and preventive approach of Nursing professionals are essential for early detection and effective intervention, thus contributing to the reduction of suicide attempts and their tragic consequences.

Introduction. Attempted suicide represents the third cause of death among people aged 15 to 29 and most suicides occur in low- and middle-income countries. In the face of suicidal behaviors and behaviors, health professionals must work to promote protective factors that provide security for the sustenance of life and focus on minimizing predisposing circumstances, which may at some time precipitate lethal behaviors. Objective. Characterize protective factors and nursing interventions in primary prevention, monitoring and control of suicidal behaviors or a potential act of suicide. Methodology. The study was developed as a descriptive bibliographic review, including scientific publications available in databases such as Scopus, PubMed, SciELO, ProQuest, the Regional Portal of the Virtual Health Library, Dialnet and Redalyc. The search strategy integrated the use of Google Scholar and the search engines of each database. Results. Protective factors such as social support, positive family dynamics, emotional regulation and self-esteem are essential to prevent suicidal behaviors. Nursing interventions should focus on enhancing these factors through preventive actions from primary care, addressing education, early identification of risks and creation of support networks. In addition, it is necessary to establish standardized protocols, strengthen continuous training and promote a humanized approach. The therapeutic relationship, based on empathy and trust, is key to identifying risks, promoting healthy behaviors, and reintegrating patients into their community environments. Conclusion. Protective factors are essential in suicide prevention, while the nursing role focuses on implementing preventive strategies, strengthening therapeutic bonds based on empathy and trust, and managing risks effectively.

Introduction: Reconstruction of traumatized limbs involves complex challenges in injuries affecting vascular, bone and soft tissue structures. Free flaps are preferred in severe cases due to their ability to ensure functional and stable coverage through vascularized transplantation. The choice of flap is based on the location, size of the defect and availability of tissue, with options such as fasciocutaneous and helix flaps standing out. In exposed fractures type IIIB and IIIC according to Gustilo Anderson, the use of flaps is crucial to manage vascular compromise and reduce infections, optimizing the function and aesthetics of the limb. Objective: To evaluate the risks and benefits of flap reconstruction in the treatment of traumatic injuries of the lower limbs, through a comparative analysis that considers the severity of the injury and the intrinsic factors of each patient, in order to determine the viability of this technique. Materials and methods: This is a literature review on reconstructive strategies with flaps in traumatic injuries of the lower limbs, based on recent studies (2019-2024) with a high level of evidence. Six articles were analyzed after an exhaustive search in scientific databases using rigorous eligibility and clinical relevance criteria. Results: Locoregional flaps are an effective and versatile option for the reconstruction of traumatized lower limbs, especially in settings with limited resources or patients with comorbidities. Techniques such as the DIEP, Propeller and hemitriceps surae flaps provide reliable coverage, reduce complications and offer good aesthetic and functional results, being a valuable alternative to microsurgical flaps. Conclusions: The use of flaps for lower limb reconstruction is an effective, reliable, and adaptable technique that improves the functional and aesthetic quality of life of patients. The appropriate selection of the technique depends on the characteristics of the defect, the patient's comorbidities, and the experience of the medical team. Although serious complications are not frequent, they should be carefully considered to minimize the risk of reconstruction failure. General area of ​​study: Medicine.

Introduction. In recent years, forensic genetics has become key evidence in multiple criminal and civil proceedings. With the ability to confirm or eliminate a suspect, as well as to determine family relationships, for the criminal and civil process, a new and valuable means of solving crimes. It is an essential technique that is added to those that have been used until now. In the criminal field, it allows analyzing criminal strategies and identifying those responsible, improving judicial and police management of different legal matters. Objective. Analyze the importance of genetic profiles in people deprived of liberty by taking oral swab samples to apply in criminal and judicial investigations and identification of corpses. Methodology. The research was characterized by being a bibliographic review with a descriptive approach, documentary and non-experimental design, cross-sectional cohort with a retrospective approach. To carry out this review, digital articles were accessed through various databases such as Medline, Scopus. 30 scientific articles were reviewed and 15 articles were selected through the inclusion and exclusion criteria. Results. The studies analyzed demonstrate the proven practical usefulness of the highly effective study of the genetic profile in people deprived of liberty in penitentiary centers. Conclusion. The inclusion of identifying genetic data of people involved in a criminal act, search for missing persons and prison riots is very useful and important.
