Perforation of the superior vena cava during ECMO catheterization in two neonates with congenital diaphragmatic hernia: a cause of accidental death

Congenital diaphragmatic hernia (CDH) is a defect seen in approximately 1 in 3500 live births. A complication of CDH is the herniation of abdominal contents into the chest cavity through the defect, which may prevent normal intrauterine development of the lungs. The resultant pulmonary hypoplasia and pulmonary hypertension causes respiratory distress in the newborn, usually requiring some form of intervention before the defect is surgically corrected (Embryology for Surgeons. Baltimore, MD: Williams & Wilkins; 1994:491-539). Extracorporeal membrane oxygenation, which involves cannulation of the superior vena cava (SVC), is often used to manage these infants. However, the mediastinal shift that often occurs with CDH can cause an abnormal acute angulation of the SVC, which during cannulation can result in trauma and possible perforation of the SVC. We present 2 autopsy cases where the infants accidentally died as a result of extracorporeal membrane oxygenation cannulation.     

Comparative Assessment of a Novel Photo‐Anthropometric Landmark‐Positioning Approach for the Analysis of Facial Structures on Two‐Dimensional Images

Positioning landmarks in facial photo‐anthropometry (FPA) applications remains today a highly variable procedure, as traditional cephalometric definitions are used as guidelines. Herein, a novel landmark‐positioning approach, specifically adapted for FPA applications, is introduced and, in particular, assessed against the conventional cephalometric definitions for the analysis of 16 landmarks on ten frontal images by two groups of examiners (with and without professional knowledge of anatomy). Results showed that positioning reproducibility was significantly better using the novel method. Indeed, in contrast to the classic approach, very low landmark dispersions were observed for both groups of examiners, which were usually below the strictest clinical standards (i.e., 0.575 mm). Furthermore, the comparison between the two groups of examiners highlighted higher dispersion consistencies, which supported a higher robustness. Thus, the use of an adapted landmark‐positioning approach proved to be highly advantageous in FPA analysis and future work in this field should consider adopting similar methodologies.     

Development and Validation of a Method Using Dried Oral Fluid Spot to Determine Drugs of Abuse

A liquid chromatography–mass spectrometry method using dried oral fluid spots was developed and validated for the simultaneous quantification of cocaine, benzoylecgonine, cocaethylene, amphetamine, and 3,4‐methylenedioxymethamphetamine. The oral fluid was applied to a Whatman 903 grade paper and submitted to a drying time of 2.5 h. The extraction procedure was optimized by chemometric approach using simplex centroid design. Spots were extracted with a mixture of acetonitrile, buffer, and methanol. Calibration curves covered a linear concentration range of 40–500 ng/mL. Validation parameters of linearity, precision, accuracy, selectivity, carryover, matrix effects, and stability were evaluated and showed satisfactory results. Spot homogeneity was also satisfactory, with less than 15% of deviation from nominal concentration. Spot volume did not influence accuracy when less than 100 μL of the sample was applied to the spot. The validation of the proposed method suggests a potential application in different scenarios in toxicology.     

Beyond deterrent enforcement styles: Behavioural intuitions of Chinese environmental law enforcement agents in a context of challenging inspections

This article extends the study of regulatory enforcement on three levels. First, it separates enforcement style elements during inspections and sanction decision‐making work, creating a more realistic measurement. Second, it focuses on how these elements function in a context where it is hard in practice to achieve deterrence. Third, it assesses how agents view the effectiveness of combinations of style elements in such a context. To do so, it uses survey and interview data with street‐level environmental officials in Guangzhou, China. It finds that the agents studied practise enforcement that goes beyond deterrence and uses education and persuasion more effectively. It finds that the behavioural assumptions of these agents are to a large extent in line with the available regulatory literature, although agents are very unlikely to have consulted such studies. Therefore, the article concludes that law enforcement agents can develop nuanced and appropriate behavioural intuitions through their everyday work experiences.     

Fishing,food, and harbor community development in Massachusetts

Fishing communities are highly dependent on fishing and maritime economies. Regulations and techniques attempt to control quotas, types of fish caught, and the gear utilized in the industry. Furthermore, societal preferences and markets dictate the value of the fish transacted. The purpose of this paper is to analyze the relationship and recent changes between fishing and community development in two fishing communities in Massachusetts: Gloucester and New Bedford. Moreover, I also discuss the role that fish food plays in cities and their foodways. The research asks how these communities have adapted to changes in fishing stocks, techniques, socioeconomic trends and regulations during the last two decades. A resilience public affairs approach centered on seven governance dimensions of fisheries is utilized to analyze the case studies. It is argued that specializing in niche markets, developing adequate industry facilities, and nurturing the cultural aspects endemic to each fishing community has positively influenced the communities' capacity to withstand major societal transformations. The harbor plans for Gloucester and New Bedford provide some plausible directions toward future improvements in the fishing sector.     

The False Narrative On Basic Rights

正The U.S. has made human rights a central component of its foreign policy since the Jimmy Carter administration(1977-81). Carter, seeking to improve the international image of the U.S. in the aftermath of the Viet Nam War, criticized human rights abuses and the lack of political freedoms in various U.S.-allied dictatorships, including Chile and Nicaragua. Such criticisms were designed not only to enhance the reputation of the U.S. internationally but also to buttress and give credibility to its ongoing ideological warfare against the socialist world.     

Conflict or Cooperation? Political Relations between Governors and Mayors in Major Cities in Argentina

This article explores the nature of the relations between the governors and the mayors of major cities in Argentina. The vast majority of the literature assumes that municipal governments in Argentina are weak, and that mayors therefore align with the provincial authorities. This study argues that there is more diversity in the relations between officials of both levels, and that, in some cases, these relations are openly contentious. Four ideal types of relations are identified, based on political affiliation and type of relation, through the systematisation of 43 cases of major Argentine cities.     

The Dark Side of Social Capital Re-examined from a Policy Analysis Perspective: Networks of Trust and Corruption

Abstract

This work deepens the analysis of the “dark side” of social capital proposed by Alejandro Portes and Patricia Landlot and revisited by Peter Graeff. For this purpose, it combines the individualistic approach of economic theory with the social perspective of other social sciences to study the economics of corruption embedded in a social structure (a network of trust). It assesses the importance of social relations as a necessary condition to achieve corrupt objectives. To do so, a model of corrupt public contracts embedded in networks of trust is built. Theoretical evidence is found on the importance of networks of trust for the success of corrupt deals between officials and recipients. In addition, seeds are sown for future research and analysis of the role of institutions and monitoring agencies. Finally, the foundation is laid for research in the field of experimental economics to conduct an empirical examination of this proposed model and some policy implications are derived.
