Objectives: To analyze the characteristics of sudden death associated with sexual activity to provide recommendations for forensic identification.
Methods: A retrospective analysis was conducted on autopsy cases accepted by Forensic Identification Center of Huazhong University of Science and Technology from 1998 to 2018, and a total of 15 cases of sudden death associated with sexual activity were screened out. The general information, case data and pathological changes of 15 cases were collected to find the relationship between sexual activity and sudden death.
Results: The ratio of male to female was 1.5∶1. The average age of males was 50.1 years and that of females was 35.0 years. Coronary artery diseases and brain diseases accounted for most of the cases (12/15). Sexual partners were associated with locations of deaths and body dumping behaviors.
Conclusions: Sudden death associated with sexual activity, although rare, may occur in people over 30 years old with pre-existing heart or brain diseases, which should be paid attention to in forensic practice.

We develop a model that integrates evolutionary matrix game theory with Mendelian genetics. Within this framework, we define the genotype dynamics that describes how the frequencies of genotypes change in sexual diploid populations. We show that our formal definition of evolutionary stability for genotype distributions implies the stability of the corresponding interior equilibrium point in the genotype dynamics.

Background: Sexually transmitted infections (STIs) remain a major public health threats in sub-Saharan Africa (SSA). Delay in seeking care is a significant barrier for the prevention and control of STIs. This study aimed to assess the proportion of women seeking STI-related care and its determinants in SSA.

Intergenerational games offer a potential channel to impact parent-youth sexual health communication. The "Secret of Seven Stones" (SSS) is an 18-level online adventure game and parent website designed to engage parents and youth (11-14 years) in conversations about healthy dating relationships and sexual behavior and to provide sexual health skills training to youth. Study hypotheses were that SSS exposure would increase sexual health parent-child communication, increase youth intentions to delay sexual debut, and reduce youth exposure to situations that promote sexual activity.

We analyzed the patterns of transmission in the 2022 clade IIb mpox epidemic as it unfolded in the European population of men who have sex with men (MSM). We developed an agent-based model that simulates sexual pair formation, incorporating both brief and longer-term sexual relationships. The model implements survey data on the sexual behavior of MSM and accounts for the highly heterogeneous nature of the sexual contact network within this community.
