CT‐Guided,Minimally Invasive,Postmortem Needle Biopsy Using the B‐Rob II Needle‐Positioning Robot

CT‐guided, minimally invasive needle biopsy techniques can be used to retrieve tissue or body fluid samples for histologic tissue diagnoses in forensic investigations. The purpose of this study was an evaluation of CT‐guided needle‐positioning robot B‐Rob II. To operate under CT guidance, we adopted the B‐Rob II robotic needle placement system and its workflow. The accuracy and speed of the procedure were tested on a gelatin phantom in a series of 21 biopsies. We achieved an average needle placement accuracy of 1.8 mm (±1.1 mm) using robotic assistance. The procedure required an average of 2 min 21 s. The needle placement accuracy for minimally invasive needle biopsies using the B‐Rob II biopsy robot is sufficiently accurate and fast for forensic postmortem examinations of focal organ changes. Further tests will be performed to test the feasibility of the robot for performing biopsies of focal organ changes in human bodies.

Allegations Lost and Found: the afterlife of Dominican sugar slavery

In 2007 visual media reports revived allegations that sugar was being produced in the Dominican Republic using the labour of Haitian slaves. Beyond raising the general public's awareness of the plight of migrant sugarcane workers, the films and their surrounding publicity have led to the Dominican sugar slavery allegation being adopted in yearly global overview reports produced by agencies of the US Departments of Labor and State. The Dominican Republic has as a result been put back on an aid-and-trade-sanctionable track, more than 15 years after sugar slavery last featured as an allegation in any leading monitor group's reports. All this, plus evidence that one videographer knew central aspects of the allegation to be false at the moment of its public release, mark the revival of the Dominican sugar slavery allegation as a precursor to the media furor triggered by the Kony 2012 ‘viral video’. Analysis of the visual media afterlife of Dominican sugar slavery suggests that the ‘Kony effect’ may be less new than meets the eye, for Kony 2012 is not the first video campaign to promote yesterday's human rights crisis as today's imperative for action.     

Action Research at the Intersection of Structural and Family Violence in an Immigrant Latino Community: a Youth-Led Study

The current study addresses the lack of research exploring the social and emotional impact of anti-immigrant policy on Latino communities, and the intersection of anti-immigrant climates with other family stressors, like domestic violence (DV). In this paper we describe a qualitative study led by the participatory action research group La Voz Juvenile de Caminar Latino. Youth researchers conducted semi-structured interviews with Latino men, women, and youth participating in a domestic violence program. Using an inductive approach to thematic analysis, researchers identified themes that reflect how Latino families with histories of DV experience an increasingly anti-immigrant climate. All participants in this study described emotional stress, fear, and restrictions in their day-to-day life attributed to the anti-immigrant sociopolitical climate, and adults also spoke to work-related stress and economic insecurity. Both adults and children described harassment by strangers, coworkers, and/or peers. With regard to DV, women tended to describe immigration stress as exasperating family conflict, while men viewed these external stressors as discouraging DV. Distrust of police and other formal supports was a key theme underlying adult and youth perceptions of help-seeking for DV. The findings of this study suggest that anti-immigrant sentiment and policy creates undue stress for Latino families and barriers to formal help-seeking for DV. The participatory research process provided a corrective experience for youth witnesses of DV and prioritizes the voices of those most affected by immigration policies and violence.     

Parental and Others’ Responses to Physical Sibling Violence: a Descriptive Analysis of Victims’ Retrospective Accounts

Although sibling abuse may be the most common form of family violence, relatively few studies have been conducted on this topic. The current exploratory study addressed this gap in the literature through analyses of thematic categories in sibling abuse narratives gathered from an online survey of sibling violence victims. All data was collected via an online survey. Participants who reported being victimized by physical sibling violence were asked to reflect on how others—family members, professionals, and friends—responded to knowledge of the abuse. Results demonstrate a need for general education about sibling violence, particularly for parents who might minimize or normalize their children’s violent conflicts. Additionally, parents need assistance in developing appropriate responses to sibling violence, as participants often perceived their parents to be ineffective at preventing or stopping the abuse. Finally, this study suggests that negative or unhelpful parental responses can be as harmful as the sibling violence itself.     

Effect of murine retroviral infection on hair and serum levels of cocaine and morphine.

LP-BM5 retrovirally infected female C57BL/6J mice were administered cocaine, morphine or both by daily intraperitoneal injection for 9 weeks. Drug concentrations were measured by radioimmunoassay in serum and in hair extracts. Hair samples obtained from all drug-treated mice were positive for the drug injected, while none of the saline-treated mice had detectable drug levels in hair or serum. The average morphine concentration obtained from non-infected mice was 11 ng/mg hair whereas the amount found in the LP-BM5-infected mice was significantly higher (20 ng/mg hair). Mice injected with both morphine and cocaine were given 50% of the regular dose of each drug and drug levels in the hair of these animals were approximately half that of mice injected with the full dose of the single drug. Non-infected mice treated with both drugs had a mean value of 7 ng morphine/mg hair and 374 ng cocaine/mg hair while retrovirus-infected mice had significantly higher concentrations, 10 ng morphine/mg hair and 1160 ng cocaine/mg hair (P less than 0.001). Serum concentrations of cocaine and morphine were significantly higher (P less than 0.01) in the retrovirus-infected animals from 40 min to 1.5 h. The increased concentrations of cocaine and morphine in serum during retrovirus infection are accompanied by a significant increase in the amount of drug incorporated into the hair matrix. This change indicates that retroviral infection may influence the disposition of these drugs in the systemic circulation.
