Allele frequencies and population data for 17 Y-chromosome STR loci in a Serbian population sample from Vojvodina province

Seventeen Y-chromosomal STR (short tandem repeat) loci were analyzed in a group of 185 healthy unrelated male individuals (n=185) from the population of Serbian province of Vojvodina. After minimal haplotype STR loci analysis we observed 129 different haplotypes. The most frequent haplotype was found in 13 copies, and total haplotype diversity was 99.11%. After analysis of additional eight Y-STR loci (DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 and YGATAH4) there were 176 different haplotypes observed, out of which 168 appeared in single copies, and 7 haplotypes appeared twice. The most frequent haplotype was found in three copies. The haplotype diversity (99.94%) and discrimination capacity (95.13%) were calculated. Comparisons were made with previously published haplotype data on neighbouring population samples and significant differences were demonstrated at DYS19, DYS389II and DYS393 loci. Pairwise comparison of populations revealed that our sample was significantly different only from Hungarian sample (RST=23.98%, p=0.0091).     

A forensic medicine perspective on recurring episodes of intimate partner violence

During a three year period, 418 victims of intimate partner violence (IPV) were examined and their injuries documented at the Center for Victims of Violence (CVV) in Hamburg, Germany. All victims were questioned if their acute injuries were attributable to recurring acts of violence by the same intimate partner. The victims' experiences with recurring IPV were analyzed and associated risk factors as well as findings of acute physical injuries were integrated into the assesment. Overall, women were significantly more often victims of recurring episodes of IPV than men. In 35.4% of cases, victims of recurring IPV sustained injuries to three or more body regions. However, women who were victimized during a single act of violence, presented with the same distribution of injuries in only 21.1% of cases (p = 0.01). The results emphasize the fact that IPV often manifests itself in a spiraling escalation of physical violence. Furthermore, blunt force trauma to the head was diagnosed significantly more often (p = 0.05). The risk of sustaining a head injury was equally high for women who experienced a first-time violent episode by their ex-partner as it was for married women or women living in a non-marital partnership during recurring episodes of IPV. In an effort to reduce the increased risk for victims of IPV, health care personnel are highly encouraged to partake in forensic medicine based continuing education. This preventative measure may prepare clinicians to recognize IPV earlier as well as to treat and advise clients appropriately.
