Death by potassium chloride intravenous injection: evaluation of analytical detectability

Potassium chloride intravenous injection is used in suicide attempts and lethal procedures for state-sanctioned punishment. Owing to its relatively high concentrations in hemolyzed blood (25-80 mM) compared to serum (about 4 mM), it is difficult to conclude potassium poisoning by postmortem analysis of biologic samples. A 41-year-man was found dead with an injection sign on his foot and a syringe close to the corpse. No particular signs were noted during the autopsy. Blood, bile, and urine were submitted to xenobiotic screening procedures used in the laboratory. Syringe content was found positive to potassium ions. Blood potassium concentration was determined by ion-selective electrode measurement (range 3.0-150 mM). Blood was found positive for diazepam at therapeutic level. Potassium concentration was 160.0 (cardiac) and 87.3 mM (femoral blood). Our results show that potassium concentration was significantly higher in heart blood in a suicide case. Hence, the general issue of considering potassium poisoning hardly demonstrable by toxicology needs to be questioned and thoroughly studied.     

UK government's Open Standards Consultation – A step in the wrong direction?

This paper comments on UK government's Open Standards Consultation which opened on 7 February 2012. It questions the UK government's mandating of open standards defined as standards which include patents licensed on a royalty free basis. The paper suggests that instead of promoting a level playing field, the government's policy will actually restrict competition and hinder interoperability. This policy is contrary to EU policy in a number of different fields which have all accepted, despite significant in-depth debate on this issue, that the best way to ensure the most effective competition, innovation and interoperability is to allow both royalty free patents and royalty bearing patents to compete provided the latter are licensed on FRAND terms. Lastly the paper suggests that the public procurement rules are not the place to apply industrial policy, instead a full market analysis should be conducted involving other government departments such as BIS and the IPO.     

An Exceptional Case of Acute Respiratory Failure Caused by Intra‐Thoracic Gastric Perforation Secondary to Overeating

An 18‐year‐old female patient arrived at the emergency department complaining of abdominal pain and fullness after a heavy meal. Physical examination revealed she was filthy and cover in feces, and she experienced severe abdominal distension. She died in ED and a diagnostic autopsy examination was requested. At external examination, the pathologist observed a significant dilation of the anal sphincter and suspected sexual assault, thus alerting the Judicial Authority who assigned the case to our department for a forensic autopsy. During the autopsy, we observed anal orifice expansion without signs of violence; food was found in the pleural cavity. The stomach was hyper‐distended and perforated at three different points as well as the diaphragm. The patient was suffering from anorexia nervosa with episodes of overeating followed by manual voiding of her feces from the anal cavity (thus explaining the anal dilatation). The forensic pathologists closed the case as an accidental death.     

Extraction of DNA from Skeletonized Postcranial Remains: A Discussion of Protocols and Testing Modalities

This paper provides a retrospective of the DNA analysis performed by the Armed Forces Medical Examiner–Armed Forces DNA Identification Laboratory between 1990 and 2018. Over 13,000 postcranial osseous materials, comprised of wartime losses from World War II, the Korean War, and South‐East Asia, were examined by the following: mitochondrial DNA sequencing, a modified AmpFlSTR® Yfiler?, AmpFlSTR® MiniFiler?, PowerPlex® Fusion, or NGS. Four different DNA extraction protocols were used: incomplete demineralization coupled with an organic purification; complete demineralization with an organic purification; complete demineralization with an inorganic purification using QIAquick PCR Purification Kit; and a protocol designed specifically for use with next‐generation sequencing. In general, complete demineralization coupled with an organic purification was the optimal extraction protocol for sequencing of mitochondrial DNA, regardless of the osseous element tested. For STR testing, demineralization paired with an inorganic purification provided optimum results, regardless of kit used or osseous element tested.

Identity Formation in Early and Middle Adolescents From Various Ethnic Groups: From Three Dimensions to Five Statuses

We used three identity processes (i.e., commitment, in-depth exploration, and reconsideration of commitment) from a recently developed model of identity formation to derive empirically identity statuses in a sample of 1952 early and middle adolescents. By means of cluster analysis, we identified five statuses: achievement, foreclosure, moratorium, searching moratorium, and diffusion. Specifically, we found an intra-status differentiation within moratorium, unraveling the positive and negative facets of this status documented in prior literature. The five clusters could be meaningfully distinguished on a number of variables, such as personality features, psychosocial problems, and parental relationships. These findings indicated that a valid distinction in identity statuses could be made in early and middle adolescence. Finally, age and ethnic background strongly affected the distribution of the participants among the five identity statuses. Implications and suggestions for future research are discussed.

Correlates of Identity Configurations: Three Studies with Adolescent and Emerging Adult Cohorts

Adolescence and emerging adulthood are two core developmental periods in which individuals can develop a meaningful identity across domains. However, there is a lack of studies exploring correlates of different identity configurations. The purpose of this article was to fill this gap in examining correlates of configurations characterized by identity stability or instability in both ideological and relational domains or identity stability in one domain and instability in the other domain. Three studies were presented. In the first study, we investigated links between identity configurations and internalizing problem behaviors in early and middle adolescents (N=1,891; M (age) =14; 55% female); in the second study, we focused on associations between identity configurations and identity functions in late adolescents and early emerging adults (N=1,085; M (age) =19; 63% female); in the third study, we investigated relationships between identity configurations, sense of coherence, and basic psychological need satisfaction in emerging adults (N=489; M (age) =21; 71% female). Overall, findings highlighted that participants experiencing a condition of identity stability in both domains reported a better profile than their peers displaying a condition of instability in both realms. Further, individuals with identity stability only in one domain reported intermediate scores and the effect provided by each domain varied according to the correlate examined and the age group taken into account. Implications of these findings are discussed.     

Identity Styles,Positive Youth Development,and Civic Engagement in Adolescence

Identity formation is a core developmental task of adolescence. Adolescents can rely on different social-cognitive styles to seek, process, and encode self-relevant information: information-oriented, normative, and diffuse-avoidant identity styles. The reliance on different styles might impact adolescents’ adjustment and their active involvement in the society. The purpose of this study was to examine whether adolescents with different identity styles report differences in positive youth development (analyzed with the Five Cs—Competence, Confidence, Character, Connection, and Caring—model) and in various forms of civic engagement (i.e., involvement in school self-government activities, volunteering activities, youth political organizations, and youth non-political organizations). The participants were 1,633 (54.1 % female) 14–19 years old adolescents (M _age  = 16.56, SD _age  = 1.22). The findings indicated that adolescents with different identity styles differed significantly on all the Five Cs and on two (i.e., involvement in volunteering activities and in youth non-political organizations) forms of civic engagement. Briefly, adolescents with an information-oriented style reported high levels of both the Five Cs and civic engagement; participants with a normative style reported moderate to high scores on the Five Cs but low rates of civic engagement; diffuse-avoidant respondents scored low both on the Five Cs and on civic engagement. These findings suggest that the information-oriented style, contrary to the diffuse-avoidant one, has beneficial effects for both the individual and the community, while the normative style has quite beneficial effects for the individual but not for his/her community. Concluding, adolescents with different identity styles display meaningful differences in positive youth development and in rates of civic engagement.
