Eight Y chromosome short tandem repeat (STR) polymorphisms (DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392, and DYS393) were analyzed in the sample of 117 unrelated Albanian males living in Kosovo. A general STR allelic frequency pattern in the Albanian population from Kosovo corresponds to other European populations. Fourty six haplotypes were observed in single copy. The most frequent haplotypes were (DYS19-DYS385-DYS389I-DYS389II-DYS390-DYS391-DYS392-DYS393) 14-11/11-13-29-24-11-13-13 (10.26%), 14-14/17-12-28-24-10-11-12 (9.40%), 13-16/18-13-30-24-10-11-13 (9.40%), and 14-17/17-13-31-24-10-11-13 (9.40%). 相似文献

Only approximately one-half of the 456 women who were killed or almost killed by a husband, boyfriend, or ex-husband or ex-boyfriend in a recent national study of homicide of women accurately perceived their risk of being killed by their abusive partner. Women are unlikely to overestimate their risk; however, many will underestimate the severity of the situation. From the same study, it was found that relatively few of the victims of actual or attempted intimate partner femicide were seen by domestic violence advocates during the year before they were killed; they were far more likely to be seen in the health care system. Implications are drawn as to innovative ways that women who are abused can be identified and with skilled assessment of the danger in their relationship helped make more informed plans for their safety. 相似文献

Women who seek medical care following sexual assault are usually evaluated and treated in an emergency department (ED). Therefore, EDs can be an important source of sexual assault surveillance data. The authors compared the incidence of sexual assault presenting for emergency care in a single county during July to November of 1974 and 1991. Participants included all female sexual assault victims aged 14 and older who presented for ED evaluation. Treating physicians prospectively collected data using standardized forms. The z statistic was used to compare sexual assault incidence. There was a 60% increase in the incidence of sexual assault victims presenting for emergency care in 1991 compared to 1974, primarily due to an increase in the incidence of women presenting to the ED after rapes by known assailants. In contrast, the annual incidence of reported stranger assaults was similar in the two study years. 相似文献
