Flail Chest Following Failed Cardiopulmonary Resuscitation

Following the death of a woman with blunt force chest trauma, the question was asked how common was the finding at autopsy of a flail chest in decedents after failed cardiopulmonary resuscitation. It was suggested in court that this was an uncommon occurrence. To address this issue, autopsy cases in adults (>18 years) with rib fractures attributable to cardiopulmonary resuscitation were taken from the files of Forensic Science SA over a 7‐year period from 2008 to 2014. Flail chest injuries were defined as those arising from fractures at two sites in at least three consecutive ribs. From 236 cases with rib fractures attributed to resuscitation, a total of 43 flail chest injuries were found in 35 cases (14.8%). The majority occurred in the 60‐79‐year‐old age group. These data suggest that flail chest injuries are a more common sequelae of cardiopulmonary resuscitation than has been previously appreciated in autopsy cases, particularly in the elderly.     

Perspectives on Regional Differences and Intimate Partner Violence in Canada: A Qualitative Examination

Few studies have examined the impact of intimate partner violence (IPV) within rural and northern communities. The current study addressed gaps within the literature by gathering perspectives from community service providers and academic researchers in order to increase understanding about the unique needs of IPV survivors within geographically diverse regions. Interviews were conducted with ten participants from Saskatchewan, Manitoba, Alberta, and Northwest Territories. Interviews focused on the unique needs of IPV survivors within each region, gaps that exist in meeting those needs, as well as questions pertaining to a larger research study entitled, Rural and Northern Community Response to Intimate Partner Violence. Results revealed several core themes relating to the unique challenges faced by IPV survivors within each region, as well as barriers to accessing services within rural and remote communities. Results also highlighted important considerations for future researchers, such as challenges that can arise when conducting research within geographically remote locations. Findings may help inform future development and implementation of services for IPV survivors residing in geographically diverse locations across Canada.     

Latinos in the war on drugs: The role of offender citizenship status and family ties on downward departures

The present study analyzes Latino drug offenders sentenced in U.S. federal courts from 2006–2014 in order to assess whether any family ties effects were contingent on offenders’ citizenship status. The findings indicate that citizenship status conditions the influence of family ties on the decision to grant downward departures, but not the decision on the magnitude of the discount granted. The findings indicate the importance of conducting intra-ethnic examinations of sentencing outcomes for Latinos rather than assuming parity in treatment and solely comparing them to other groups.     

Measuring Desiccation Using Qualitative Changes: A Step Toward Determining Regional Decomposition Sequences

The creation of a regional decomposition scoring system for western Colorado provides a model for the creation of regional systems. The development of a scoring system requires: (1) human remains, not proxies, (2) longitudinal observations, and (3) large sample size. First, an enhanced system (total body desiccation score; TBDS) was developed through observations of 40 human remains. This effort produced a categorical scoring model augmented by qualitative categories of gross tissue change. The new model was tested with retrospective photographic packets. A sample of eight donors with data collected over 3 years was selected. Monthly data points over a maximum of a 3‐year period yielded 112 data points. Correlations between TBDS and accumulated degree‐days (ADD), and total body score (TBS) and ADD were approximately equal for a TBS below ~20, but the TBDS correlated better with ADD at higher TBS scores >20. The TBDS may be used to refine postmortem interval (PMI) models in areas where remains desiccate.     

Bioelectrical Impedance as a Technique for Estimating Postmortem Interval,,

Estimation of postmortem interval (PMI) is a critical component of death investigation. A cadaver can be hypothesized to be a resistor–capacitor (RC) circuit the impedance (Z) of which changes in a quantifiable manner as the cadaver decomposes. This hypothesis was tested using bioelectrical impedance analysis (BIA) equipment to apply a current with a fixed amplitude at a single frequency to four cadavers over time and measuring two components of Z, resistance (R) and reactance (X_c). Quadratic regression analysis between Z and accumulated degree days (ADD) showed a statistically significant parabolic relationship. The parabolic relationship poses an initial challenge to the use of the method, and additional research is needed to address this issue. However, the results of the reported research support the hypothesis that Z measured using BIA has a relationship to PMI.     

Identification of Bodies by Unique Serial Numbers on Implanted Medical Devices

Visual identification is the most common identification method used by medical examiners but is not always possible. Alternative methods include X‐ray, fingerprint, or DNA comparison, but these methods require additional resources. Comparison of serial numbers on implanted medical devices is a rapid and definitive method of identification. To assess the practicality of using this method, we reviewed 608 consecutive forensic autopsies performed at a regional medical examiner office. Of these, 56 cases required an alternative method of identification due to decomposition (n = 35), gunshot wound (n = 9), blunt trauma (n = 6), or charring (n = 6). Of these 56 cases, eight (14.3%) were known to have an implanted medical device. Of these eight cases, five (63%) could be positively identified by comparing serial numbers. If an implanted medical device is known to be present, and medical records are available, identification by medical device serial number should be a first‐line method.     

Bruised Inside Out: The Adverse and Abusive Life Histories of Incarcerated Women as Pathways to PTSD and Illicit Drug Use

The majority of incarcerated women who suffer from diverse traumatic life histories including abusive home lives and intimate partner violence (IPV), develop post-traumatic stress disorder (PTSD) and struggle with heavy illicit drug use. While many have offered examinations of these relationships, the current study is among the first to utilize an integrated feminist pathways and general strain theory (GST) approach to explain them. Using data from a stratified random sample of all incarcerated women in Oklahoma (N = 334), we explore the links between, adverse childhood experiences, including physical, sexual, emotional, and childhood neglect, IPV, PTSD, and heavy illicit drug use. Our findings indicate that the effects of IPV on heavy illicit drug use are mediated by PTSD symptoms suggesting that PTSD plays a significant role in the pathway to illicit drug use among Oklahoma women prisoners. Implications for the importance of utilizing an integrated feminist pathways and GST approach in future research are offered.     

Ethnicity and Sexual Orientation as PTSD Mitigators in Child Sexual Abuse Survivors

Purpose and Potential benefits: Research, to our knowledge, has not examined the effect of demographic variables on PTSD symptoms among adult survivors of childhood sexual abuse (CSA). This study explores the relationship between demographic variables and scores of CSA survivors on the Impact of Scale (IES). Participants were 257 women CSA survivors entering outpatient treatment at a university-based mental health center. All participants reported a CSA history and presented with psychological difficulties associated with CSA. The demographic variables investigated were relationship status, religious affiliation, ethnicity, educational level, spousal educational level income, and sexual orientation. Significance tests were used to examine each variable and scores on the Total IES and Avoidance and Intrusion Subscales. Total IES and Intrusion scores differed for sexual orientation and ethnicity in accord with conventional standards of significance ( < .05). Self-reported asexuals indicated fewer intrusive and total PTSD symptoms than heterosexuals, lesbians, and bisexuals. Likewise, Hispanics reported less intrusive PTSD symptoms than Non-Hispanic Caucasians. Our findings invite further exploration of the relationship between ethnicity and sexual orientation and the long-term effects of CSA. A question for empirical investigation is whether asexuality shields against the triggering of CSA memories by a sexual relationship. Another possible area of inquiry is whether particular characteristics of Hispanic culture as a whole serve to moderate the detrimental effects of CSA.
