Recent developments in medicine and law

This article focuses on certain noteworthy legislation and cases affecting medicine and law during the period September 1, 2001, to August 31, 2002. It does not attempt to discuss every case or piece of legislation, but instead seeks to summarize some of the more significant developments in this area of law.     

Characteristics of victims coarrested for intimate partner violence

This study evaluated the frequency of coarrest in female victims who utilized 911 for intimate partner violence (IPV) and any patterns or circumstances that increased the likelihood of coarrest. All cases of police-documented IPV where a female IPV victim was arrested in conjunction with the perpetrator were included. Each incident report was reviewed to determine demographic characteristics of the victim, weapon and substance involvement, presence of children, and violence severity. Of IPV victims, 9% (131 of 1,489) were arrested. Having a weapon, alcohol use, not being married, and older age were associated with increased likelihood of arrest (p < .001). The presence of a child decreased the likelihood of victim arrest (p < .001). Race, prior incidents of IPV, offender restraining order, and incident severity were not significantly associated with coarrest. Although coarrest occurred in a minority of cases, it may deter victims from contacting police for future incidents of police.     

Twelve short tandem repeat loci Y chromosome haplotypes: genetic analysis on populations residing in North America

A total of 2443 male individuals, previously typed for the 13 CODIS STR loci, distributed across the five North American population groups African American, Asian, Caucasian, Hispanic, and Native American were typed for the Y-STR loci DYS19, DYS385a/b, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439 using the PowerPlex Y System. All population samples were highly polymorphic for the 12 Y-STR loci with the marker DYS385a/b being the most polymorphic across all sample populations. The Native American population groups demonstrated the lowest genetic diversity, most notably at the DYS393 and DYS437 loci. Almost all of the 12-locus haplotypes observed in the sample populations were represented only once in the database. Haplotype diversities were greater than 99.6% for the African Americans, Caucasians, Hispanics, and Asians. The Native Americans had the lowest haplotype diversities (Apaches, 97.0%; Navajo, 98.1%). Population substructure effects were greater for Y-haplotypes, compared with that for the autosomal loci. For the apportionment of variance for the 12 Y-STRs, the within sample population variation was the largest component (>98% for each major population group and approximately 97% in Native Americans), and the variance component contributed by the major population groups was less than the individual component, but much greater than among sample populations within a major group (11.79% versus 1.02% for African Americans/Caucasians/Hispanics and 15.35% versus 1.25% for all five major populations). When each major population is analyzed individually, the R(ST) values were low but showed significant among group heterogeneity. In 692 confirmed father-son pairs, 14 mutation events were observed with the average rate of 1.57x10(-3)/locus/generation (a 95% confidence bound of 0.83x10(-3) to 2.69x10(-3)). Since the Y-STR loci reside on the non-recombining region of the Y chromosome, the counting method is one approach suggested for conveying an estimate of the rarity of the Y-haplotype. Because the Y-STR loci are not all in disequilibrium to the same extent, the counting method is a very conservative approach. The data also support that autosomal STR frequencies can be multiplied by the upper bound frequency estimate of a Y-haplotype in the individual population group or those pooled into major population groups (i.e., Caucasian, African American, Hispanic, and Asian). These analyses support use of the haplotype population data for estimating Y-STR profile frequencies for populations residing in North America.     

Depressive symptoms in women experiencing intimate partner violence

The study was a cross-sectional examination of African American women positive for intimate partner violence (IPV) who presented to the medical or psychiatric emergency department (ED) for treatment. African American women with a recent history of IPV who presented following an attempted suicide (n = 100) were compared to demographically comparable African American women who were IPV positive who had not attempted suicide and presented for treatment of another condition(n= 100). Women completed face-to-face interviews on several measures, including demographics and the Beck Depression Inventory-II (BDI-II). Overall, there were no demographic differences between cases and controls. Attempters reported statistically significant higher scores on all 21 BDI-II items than did nonattempters. Four BDI-II items had effect size values in the medium range: sadness, self-dislike, suicidal thoughts, and feelings of worthlessness. These four items can be used as a brief screen in the ED to detect female patients positive for IPV at increased risk for suicidal behavior.     

Peer Victimization,Social Support,and Psychosocial Adjustment of Sexual Minority Adolescents

The present study examined the link between sexual orientation and adjustment in a community sample of 97 sexual minority (gay male, lesbian, bisexual, and questioning) high school students, taking into account their experiences of peer victimization and social support within peer and family contexts. Adolescents were identified in a large-scale survey study conducted at 5 high schools. They were matched to a comparison sample of their heterosexual peers. Sexual minority adolescents reported more externalizing behaviors and depression symptoms than heterosexual youth. Compared to their heterosexual peers, sexual minority youth reported more sexual harassment, more bullying, less closeness with their mothers, and less companionship with their best friends. There were no significant differences between gay male, lesbian, bisexual, and questioning adolescents. Overall, both victimization and social support mediated the link between sexual orientation and psychosocial symptoms. Among sexual minority youth, the link between social support and externalizing was mediated by experiences of peer victimization. These findings highlight the contextual risk and protective factors associated with non-heterosexual sexual orientation in accounting for the emotional and behavioral problems in this population.

Intraventricular hemorrhage originating from choroid plexus angioma in a road accident victim

A 76-year-old woman sustained severe multiple injuries when hit by a car. During the treatment a massive intraventricular hemorrhage was found by computer tomography. The postmortem examination revealed no craniocerebral injuries except for a small contused wound of the scalp. Microscopic examinations revealed a choroid plexus angioma in the lateral ventricle as the cause of the hemorrhage into cerebral ventricles.     

Destructive decision-making in developing countries

In most developing countries strategic decision-making has been largely based on false premises that have led to destructive results. One set of false premises stems from the assumption that development can be dissociated from the destructively exponential growth in developed countries, from the limits on the planet's physical resources and from complex ecological linkages. Another set is grounded on the popular myths of entrenched development economics: particularly, the enshrining of GNP as the overall indicator of progress, and the concomitant withdrawal of attention from poverty and concentrated wealth, unemployment, and the injurious effects of many modern technologies. These destructive premises tend to reinforce the evolving institutions of new-style empire and oligarchy.More successful development requires standing present development policies on their head through development goals calling for (1) a recognition of redistributive and nonmaterial growth possibilities, (2) redistributive, material and nonmaterial growth in developing countries, (3) redistributive, nonmaterial growth in overdeveloped countries, with a major slowing down of material consumption, (4) large-scale employment projects in developing countries, and (5) the fostering and use of more constructive technologies. All such shifts, however, would require—and tend to lead toward—substantial, long-term changes in the sociopolitical structure of developing countries and the world society.This paper is based on and adapted from The Limits of Development Administration, the keynote paper presented in October 1972 at the U.N. Public Administration Division's conference on development administration in Kiev, USSR, and Unemployment: The Snag in Development, prepared at Kiev and published in The Nation, Dec. 11, 1972.     

Cognitive tempo,violent video games,and aggressive behavior in young boys

In a factorial design, impulsive and reflective children played video games with aggressive or nonaggressive themes. Interpersonal aggression and aggression toward inanimate objects were assessed in a free-play setting and interpersonal aggression was assessed during a frustrating situation. Results indicated that subjects who played the video game with aggressive content exhibited significantly more object aggression during free-play and more interpersonal aggression during the frustrating situation than youngsters who played nonaggressive video games. Aggressive behavior was unaffected by cognitive tempo.
