Although many cases of fatal hydrogen sulfide poisoning have been reported, in most of these cases, it resulted from the accidental inhalation of hydrogen sulfide gas. In recent years, we experienced 17 autopsy cases of fatal hydrogen sulfide poisoning due to the inhalation of intentionally generated hydrogen sulfide gas. In this study, the concentrations of sulfide and thiosulfate in blood, urine, cerebrospinal fluid and pleural effusion were examined using GC/MS. The sulfide concentrations were blood: 0.11-31.84, urine: 0.01-1.28, cerebrospinal fluid: 0.02-1.59 and pleural effusion: 2.00-8.59 (μg/ml), while the thiosulfate concentrations were blood: 0-0.648, urine: 0-2.669, cerebrospinal fluid: 0.004-0.314 and pleural effusion: 0.019-0.140 (μmol/ml). In previous reports, the blood concentration of thiosulfate was said to be higher than that of sulfide in hydrogen sulfide poisoning cases, although the latter was higher than the former in 8 of the 14 cases examined in this study. These results are believed to be strongly influenced by the atmospheric concentration of hydrogen sulfide the victims were exposed to and the time interval between exposure and death. 相似文献

Based on two years of fieldwork, conducted between March 2003 and March 2005 in the health care industry of the northeastern United States, this study shows that the work of family caregivers of elders goes far beyond previously recognized care in the home to acknowledge care inside health care facilities and in conjunction with community services. It reveals that family caregivers--untrained, undersupported, and unseen--constitute a "shadow workforce," acting as geriatric case managers, medical record keepers, paramedics, and patient advocates to fill dangerous gaps in a system that is uncoordinated, fragmented, bureaucratic, and often depersonalized. Detailed examination of what family caregivers actually do in traversing multiple domains reveals the extent of their contribution to and the weaknesses in the present geriatric health care system. It suggests that the experiences of family caregivers must be central to the creation of new policies and a more coordinated system that uses the complex work of family caregivers by providing the training and support that they need. 相似文献

There is a general acceptance that cellular material will transfer from one person to another person's fingernails through everyday contact. However, the level or degree of contact required to transfer sufficient cellular material in order to obtain a DNA profile is not known. This study examined swabs from the fingernails of 40 volunteers and compared the DNA profiles obtained to the daily activities of that individual. The majority (78%) of high level profiles obtained were associated with recent intimate contact. However, high level profiles were also obtained from the fingernails of individuals who shared accommodation with their partner, flatmates and/or children. Low level profiles and single profiles were associated with all levels of contact. 相似文献

There is limited research on the gendered impacts of drug policies in Canada, despite the fact that women, Indigenous women in particular, are the country’s fastest growing prisoner population, with many incarcerated for drug-related crimes. This article highlights the results of a larger qualitative study with former prisoners in Ontario and community and medical experts from across the country. Focusing on the women research participants, we consider the lack of adequate and culturally-relevant substance use and harm reduction programming in federal prisons, and suggest a reformulation of Canada’s punitive drug policies toward a health and social welfare approach. 相似文献

Objectives
This study explores the association between past-year face-to-face contact with the police and subsequent victimization reporting. It also examines whether this relationship depends on the type of encounter (citizen-initiated contacts, routine vehicle stops, invasive encounters associated with being a suspect), its perceived justness, or victim characteristics. Among victims who did not notify the police, the reasons behind this decision are assessed to understand the mechanisms through which police encounters are related to reporting.Methods
This research is the first to use longitudinal data that link the 2002, 2008, and 2011 Police Public Contact Surveys to the 2002–2014 National Crime Victimization Surveys. Multivariate logistic regression is used to examine the effect of prior contact on police notification among victims of personal (N = 1073) and household (N = 11,433) crimes.Results
Prior contact with the police has no main effect on the reporting of personal crimes; however, the negative effects of police-initiated and unjust contact are amplified for the poor and African Americans. The reporting of household crimes varies based on prior police experiences and whether they were viewed as just. Personal crime victims with invasive contact are more likely than other contact groups to attribute non-reporting to fear of reprisal.Conclusions
Using national data tells a complex story about how race/ethnicity, poverty, and recent experiences with the police interact to shape victims’ behavior. The intricacies of these findings suggest that efforts to increase reporting may need to be multifaceted and address victims’ concerns about safety and justness.157.

Substantial research has demonstrated the value of using risk assessment tools for the prediction and management of violence risk, including for intimate partner violence (IPV) (Mills, Kroner, and Morgan 2011). Such tools have been advocated for use by police officers (Hilton, Grant, and Rice 2010), but little is known about police officers’ perceptions of using these tools to inform their decision-making. Using a sample of 159 Canadian police officers (73% male, M age =?41.8 years, SD?=?8.9), the current study examined police officer’s experiences with IPV risk tools, their attitudes about using such tools, and identified predictors of these attitudes using an online survey. Most of this sample had previously used an IPV risk tool, which was most commonly the Brief Spousal Assault Form for the Evaluation of Risk (64.1%). Most police officers rated use of risk tools as at least somewhat to extremely helpful (73.5%), and 67.4% indicated that they would use a risk tool with sufficient training on it. Regression analyses indicated that police officers’ perceived IPV risk tool usefulness was significantly predicted by older respondent age and greater perceived need for guidance in responding to IPV calls. In conclusion, most police officers view IPV risk screening as valuable for informing their responses to such calls for service and are likely to embrace such decision-aids with sufficient training on their potential impact for enhancing safety. 相似文献

Costs of providing the Green Dot bystander-based intervention, shown to be effective in the reduction of sexual violence among Kentucky high school students, were estimated based on data from a large cluster-randomized clinical trial. Rape Crisis Center Educators were trained to provide Green Dot curriculum to students. Implementing Green Dot in schools (N = 13) randomized to the intervention, over five years, cost $1.6 M and included start-up ($58 K) and ongoing implementation ($1.55 M). Costs for adding a school ($25,510) were calculated based on the final year, where no start-up costs were incurred. Knowing the $25,510 cost estimate for adding Green Dot may be particularly useful for high school administrators or school boards when they were making economic decisions based on strong evidence of program effectiveness to reduce violence. 相似文献

Sex and age trends in bone mineral density (BMD) play an important role in the estimation of age-at-death (AAD) of unidentified human remains. Current methodologies lack the ability to precisely estimate age in older individuals. In this study, BMD of the cranium and femur measured by DXA were examined to establish their applicability for age estimation in older adults. BMD as measured by DXA, is most commonly used clinically for prediction of osteoporotic fracture risk. We hypothesized that weight-bearing and non-weight-bearing bones, the femur and cranium, respectively, would provide valuable insights for aging.Methods
The sample consists of 32 sets of excised cranial fragments from the Regional Forensic Center, Johnson City, Tennessee and 41 associated crania and femora from the North Carolina Office of the Chief Medical Examiner. All crania and femora were scanned using a Hologic (R) DXA scanner and data were analyzed using Student t-tests, Loess regression, and ANOVA.Results
Student t-tests indicate a significant relationship between the sexes and cranial BMD and a significant relationship between age cohorts and femoral neck BMD. The Loess regression showed different aging patterns in the cranium for females and males older than 55. And the ANOVA showed changes in femoral neck after age 55.Conclusions
These results indicate age and sex dependent changes in BMD especially for individuals over the age of 55, which offers improvement from current aging methods for older individuals. Further research using a larger sample size could improve the predictive capabilities of the model. 相似文献160.
