An analysis of UK and EU external migration control governance and mechanisms: securitization, manipulation and cooperation

This research analyses the relationship between the UK and the EU in context to external migration control. It has used a combination of Constructivism and Bourdieu to deconstruct the field of analysis and understand how an actor’s behaviour can affect the structure of the external migration control field. Bourdieu was chosen to inform the theoretical framework as his field theory allowed a number of actors to be explored. It also recognises the importance of historical relationships impacting upon current interactions. Bourdieu explain these interactions as habitual or doxical. Habitual behaviours are learnt behaviours that adhere to the norms of the field. Doxical behaviours act against the norms and are used by actors, like the UK, to gain a higher status within the field and increase key capital. The three behaviours that have been explored are; securitization, manipulation and cooperation. In order to identify these behaviours policy documentation from key actors, like Frontex, have been qualitatively coded. The analysis uses three key moments in the history of the UK and the EU to guide the exploration of the data, these are; the Maastricht Treaty (1992), the Amsterdam Treaty (1997) and the UK Immigration Act 2014. The documentation chosen for analysis ranged from unilateral, bilateral and multilateral political agreements. Other documentation includes reports from associated actors that are part of the external migration control field. The documentation reveals the extent to which habitual behaviours dominate the relationship between the actors

Burn Injury Reduces Neutrophil Directional Migration Speed in Microfluidic Devices

Thermal injury triggers a fulminant inflammatory cascade that heralds shock, end-organ failure, and ultimately sepsis and death. Emerging evidence points to a critical role for the innate immune system, and several studies had documented concurrent impairment in neutrophil chemotaxis with these post-burn inflammatory changes. While a few studies suggest that a link between neutrophil motility and patient mortality might exist, so far, cumbersome assays have prohibited exploration of the prognostic and diagnostic significance of chemotaxis after burn injury. To address this need, we developed a microfluidic device that is simple to operate and allows for precise and robust measurements of chemotaxis speed and persistence characteristics at single-cell resolution. Using this assay, we established a reference set of migration speed values for neutrophils from healthy subjects. Comparisons with samples from burn patients revealed impaired directional migration speed starting as early as 24 hours after burn injury, reaching a minimum at 72–120 hours, correlated to the size of the burn injury and potentially serving as an early indicator for concurrent infections. Further characterization of neutrophil chemotaxis using this new assay may have important diagnostic implications not only for burn patients but also for patients afflicted by other diseases that compromise neutrophil functions

Neonatal mortality risk for vulnerable newborn types in 15 countries using 125.5 million nationwide birth outcome records, 2000–2020

Objective: To compare neonatal mortality associated with six novel vulnerable newborn types in 125.5 million live births across 15 countries, 2000–2020. Design: Population-based, multi-country study. Setting: National data systems in 15 middle- and high-income countries. Methods: We used individual-level data sets identified for the Vulnerable Newborn Measurement Collaboration. We examined the contribution to neonatal mortality of six newborn types combining gestational age (preterm [PT] versus term [T]) and size-for-gestational age (small [SGA], 90th centile) according to INTERGROWTH-21st newborn standards. Newborn babies with PT or SGA were defined as small and T + LGA was considered as large. We calculated risk ratios (RRs) and population attributable risks (PAR%) for the six newborn types. Main outcome measures: Mortality of six newborn types. Results: Of 125.5 million live births analysed, risk ratios were highest among PT + SGA (median 67.2, interquartile range [IQR] 45.6–73.9), PT + AGA (median 34.3, IQR 23.9–37.5) and PT + LGA (median 28.3, IQR 18.4–32.3). At the population level, PT + AGA was the greatest contributor to newborn mortality (median PAR% 53.7, IQR 44.5–54.9). Mortality risk was highest among newborns born before 28 weeks (median RR 279.5, IQR 234.2–388.5) compared with babies born between 37 and 42 completed weeks or with a birthweight less than 1000 g (median RR 282.8, IQR 194.7–342.8) compared with those between 2500 g and 4000 g as a reference group. Conclusion: Preterm newborn types were the most vulnerable, and associated with the highest mortality, particularly with co-existence of preterm and SGA. As PT + AGA is more prevalent, it is responsible for the greatest burden of neonatal deaths at population level
