Abstract: Larvae and pupae of blow fly species are frequently used in postmortem interval estimation, their age indicating minimum time since death. Most studies have considered age estimation of larvae, neglecting study of pupae. Relative development of external pupal features is useful, but there are also internal changes during metamorphosis that may be indicators of age, utilizing histological techniques. This study aimed to optimize preservation and histological analysis of blow fly pupae, specifically Calliphora vicina Robineau‐Desvoidy and Lucilia sericata (Meigen), and to examine internal features with potential for age estimation. Effect of hot‐water‐killing and different preservatives were examined. It was determined that blow fly pupae should be pierced through the three tagma, hot‐water‐killed, and preserved in 80% ethanol as the optimal preservation for subsequent analyses. Hematoxylin and eosin stained pupal sections revealed differences in brain and thoracic muscle development throughout the pupal stage with potential for age estimation. 相似文献

Female Veterans experience intimate partner violence (IPV) at alarming rates. The Veterans Health Administration (VHA) requires foundational research to guide the development of policy and programs to detect IPV among women Veterans and provide interventions. This pilot study reports findings from in-depth qualitative interviews conducted with 12 VHA primary care providers treating female Veterans in the New England region. Although most providers indicated that they were not currently routinely screening for IPV, they expressed positive attitudes and beliefs about screening in VHA primary care settings. Themes also included the importance of a comprehensive health care response to IPV, such as interdisciplinary coordination of care and team-based approaches to detection and intervention. Barriers to routine screening were identified, as well as recommendations for training programs and clinical tools to inform the successful implementation of a standardized IPV screening and response program in VHA. Although preliminary, these findings represent an initial step in an essential line of research. 相似文献

The childbearing years are further complicated when experiences of interpersonal trauma from childhood and/or adulthood lead to symptoms of posttraumatic stress disorder (PTSD). Maternal symptoms of PTSD over time were examined in relation to supportive adult relationships and parenting experiences. Ninety-five primarily economically disadvantaged mothers reporting exposure to childhood maltreatment and/or intimate partner violence were assessed from pregnancy through 2-years postpartum. Latent class growth analysis of PTSD symptoms indicated a 2-group model: stable low (82%) and moderate dysfunction (18%). The stable low group reported higher levels of support from romantic partners and family members, but not friends, and lower levels of parenting distress compared to the moderate dysfunction group. Results highlight individual variability in adaptation after violence exposure; current support from romantic partners and family members may have helped maintain lower PTSD symptoms for some trauma-exposed mothers. Psychological interventions aimed at reducing the impact of trauma exposure on parenting should consider promoting ongoing social support. 相似文献

An automated headspace gas chromatography method was developed for the determination of formate (formic acid) in postmortem specimens, based on the in situ sulfuric acid-methanol methylation of formic acid to methyl formate. Diisopropyl ether was used as an internal standard. The method was applied to over 150 postmortem cases where methanol was detected. Of the 153 cases presented, 107 deaths were attributed to acute methanol toxicity. In the vast majority of the remaining 46 deaths, the methanol was determined to be present as a postmortem or perimortem artifact, or was otherwise incidental to the cause of death. Of the 76 victims who were found dead and blood was collected by the medical examiner, all but one had a postmortem blood formate concentration greater than 0.50 g/L (mean 0.85 g/L; n = 74). The sole exception involved suicidal ingestion of methanol where the blood methanol concentration was 7.9 g/L (790 mg/100 mL) and blood formate 0.12 g/L. In 97% (72/74) of the cases where blood was available, the blood formate was between 0.60 and 1.40 g/L. In 31 of the 153 cases, the victim was hospitalized and blood obtained on admission or soon after was analyzed for methanol and formate during the subsequent death investigation; the vast majority (27/30) had antemortem blood formate concentrations greater than 0.50 g/L. Cases with samples taken prior to death with blood formate concentrations less than 0.5 g/L can readily be explained by active treatment such as dialysis. The blood formate method has also been useful in confirming probable perimortem or postmortem contamination of one of more fluids or tissues with methanol (e.g., windshield washer fluid or embalming fluid), where methanol ingestion was unlikely. 相似文献

In Washington State, like many states, there is a shortage of forensically trained mental health clinicians to work with criminal justice‐involved individuals. At the direction of the state legislature, a collaborative project was undertaken by the University of Washington, the state Department of Social and Health Services, and a state psychiatric hospital to develop a proposal for a jointly sponsored forensic teaching service. The authors reviewed the literature, surveyed and interviewed forensic psychiatry and psychology training directors, and conducted site visits of selected training programs that offer multidisciplinary training or have affiliations with state hospitals. The authors conducted focus groups of additional stakeholders, including clinicians and patients in forensic settings, to better understand the needs in Washington. The authors report on several common benefits and barriers to establishing forensic teaching services. Other states and forensic programs may find this article useful in identifying common considerations for forensic mental health teaching services. 相似文献

De Novo Advanced Adult‐Onset Offending: New Evidence from a Population of Federal Correctional Clients 下载免费PDF全文
Matt DeLisi Ph.D. Katherine N. Tahja M.A. Alan J. Drury Ph.D. Michael J. Elbert Ph.D. Daniel E. Caropreso M.A. Timothy Heinrichs Ph.D. 《Journal of forensic sciences》2018,63(1):172-177
Adult antisocial behavior is almost always predated by delinquency during childhood or adolescence; however, there is also evidence of adult‐onset criminal offending. This study examined this controversial subgroup of offenders using self‐reported and official data from a total population of federal correctional clients selected from the Midwestern United States. Difference of means t‐tests, chi‐square tests, and logistic regression models found that 11.7% of clients had an adult onset of offending and 2.7% of clients (n = 23) had an onset occurring at age 60 years or older. This group—introduced as de novo advanced adult‐onset offenders—had high socioeconomic status, mixed evidence of adverse childhood experiences, and virtually no usage of drugs with the exception of alcohol. These offenders were primarily convicted of social security and white‐collar crimes and evinced remarkably low psychopathology and criminal risk. More research is needed to replicate the phenomenon of de novo advanced adult‐onset offending. 相似文献

Research Summary
The Florida Department of Juvenile Justice has implemented a process to evaluate the treatment quality of interventions provided statewide in all long‐term residential programs. In the current study, we examine the predictive validity of this treatment quality component in the prediction of recidivism of youth (N = 2,397) who completed juvenile justice residential programs from July 1, 2013 to June 30, 2014. We use hierarchical linear modeling to assess the effects of treatment quality (as youth are nested within programs), controlling for demographic and criminal history factors. The results indicate that higher average treatment quality scores of interventions received within a residential program decreased the likelihood of subsequent arrest, conviction, and reincarceration, whereas the highest treatment quality score of any specific intervention provided within the program decreased the odds of reincarceration only.Policy Implications
In this study, we confirm the importance of fidelity and implementation quality in the provision of crime prevention treatment interventions to serious, deep‐end juvenile offenders. Additionally, our results shed light on the ability of a juvenile justice agency to measure treatment quality in a substantively meaningful way with the use of limited additional resources. The services provided to keep communities safe, prevent future offending, and rehabilitate juvenile offenders must be held accountable for producing such outcomes, and one method of measuring such compliance is to evaluate the quality of the interventions with respect to staff training, fidelity adherence, evaluation, and corrective action processes. 相似文献219.

Cosmetic procedures are common and utilize many techniques to obtain aesthetically good outcomes for patient satisfaction with acceptable safety standards. Cosmetic procedures that involve the gluteal region are becoming increasingly popular as various procedures can target the gluteal region such as liposuction, tumescent liposuction, cosmetic filler injections, autologous fat transfer, depot drug delivery, and implants. Complications of cosmetic gluteal procedures can be localized or systemic with systemic complications being responsible for most deaths. These reported systemic complications include sepsis, thromboembolism, fat embolism with or without fat embolism syndrome, macroscopic fat embolism, anesthesia‐related and blood volume abnormalities. We herein report 10 deaths due to elective gluteal cosmetic procedures. Autologous fat transfer (fat grafting, lipoinjection) following liposuction resulted in 8 of 10 fatal outcomes of the gluteal aesthetic procedures. A comprehensive discussion of gluteal anatomy, gluteal contouring procedures, and the approach to such cases is presented along with the autopsy findings of the reported cases. 相似文献
