Discourses and practices of the regionalisation of foreign and security policies: the cases of West Africa and South America
The process of the regionalisation of foreign and security policies, its conditions of
emergence and evolution, is the core object of study of this doctoral thesis. This
research has two aims, first it seeks to construct a new framework to understand and
conceptualise regionalisation processes and second, applying this framework to draw
conclusions on the paths these processes take in West Africa and South America.
In this research I take issue with the way in which IR approaches present regional
projects as the ‘natural’ or ‘rational’ response of nation states to a combination of
objective and ideational factors. A more thorough explanation requires an account of the
ways in which these factors are themselves constituted, maintained and shaped by
discourses and power relations between the relevant actors, as well as through the
concrete practices the actors deploy. I thus conceptualise regionalisation as an interplay
between discourses and practices of actors ‘inside’ and ‘outside’ the region.
Methodologically, the analysis uses a poststructuralist discourse analysis and an
interpretative process tracing that relies mainly on ethnographic work.
The key empirical findings of this thesis are twofold. First, historically constituted
discourses are crucial in determining the form and extent of the regionalisation process
– in particular the key articulations linking the concepts of state/nation and region.
Second, the comparison allowed me to demonstrate that regions are not independent
units: they are part of an international system where actors (re)produce discourses
carrying certain norms, concepts and meanings such as ‘security’, ‘development’,
‘regional integration’, etc. It is precisely the encounter between the regional and
‘external’ actors discourses which constitutes the process of regionalisation. The
meaning given to security, in particular, which emerges at the intersection of these
discourses, decisively frames the process towards either cooperation between sovereign
states or the building of a regional political community.The process of the regionalisation of foreign and security policies, its conditions of

Factors Influencing Quality of Life in Survivors of Head and Neck Cancer: a preliminary study
Objectives: Time after diagnosis, survivors of head and neck cancer may perceive a decrease in their quality of life due to suffering from different sequelae. This preliminary study aims to describe which factors influence survivors of head and neck cancer quality of life.
Data Sources: A cross-sectional study was performed. Demographic and clinical factors, quality of life (global health status), pain (pressure pain thresholds), physical fitness (overall fitness), functional capacity, and fatigue were evaluated. A multiple regression model was undertaken to check which outcomes could impact quality of life. A total of 53 survivors of head and neck cancer participated in this study. Upper trapezius pres- sure pain threshold, overall fitness, and global fatigue were significant predictors of global health status, and when combined, they explained 42.10% of the variance in the global health status score.
Conclusion: Quality of life perceived by survivors of head and neck cancer is influenced by pain, physical fit- ness, and fatigue reported. This association of outcomes may act as a symptom cluster for survivors of head and neck cancer.
Implications for Nursing Practice: The knowledge of this symptom cluster may help developing symptom assessment and management strategies and improving quality of life for survivors of head and neck cancer.This study was partially funded by the Fondos Estructurales de la Unio n Europea (FEDER). This study took place because of the additional funding from the Uni- versity of Granada, Excellence Actions: Units of Excellence; Unit of Excellence on Exercise and Health (UCEES).

Concurrent Assessment of Phthalates/HEXAMOLL® DINCH Exposure and Wechsler Intelligence Scale for Children Performance in Three European Cohorts of the HBM4EU Aligned Studies
Information about the effects of phthalates and non-phthalate substitute cyclohexane-1,2-dicarboxylic acid diisononyl ester (HEXAMOLL® DINCH) on children's neurodevelopment is limited. The aim of the present research is to evaluate the association between phthalate/HEXAMOLL® DINCH exposure and child neurodevelopment in three European cohorts involved in HBM4EU Aligned Studies. Participating subjects were school-aged children belonging to the Northern Adriatic cohort II (NAC-II), Italy, Odense Child Cohort (OCC), Denmark, and PCB cohort, Slovakia. In each cohort, children's neurodevelopment was assessed through the Full-Scale Intelligence Quotient score (FSIQ) of the Wechsler Intelligence Scale of Children test using three different editions. The children's urine samples, collected for one point in time concurrently with the neurodevelopmental evaluation, were analyzed for several phthalates/HEXAMOLL® DINCH biomarkers. The relation between phthalates/HEXAMOLL® DINCH and FSIQ was explored by applying separate multiple linear regressions in each cohort. The means and standard deviations of FSIQ were 109 ± 11 (NAC-II), 98 ± 12 (OCC), and 81 ± 15 (PCB cohort). In NAC-II, direct associations between FSIQ and DEHP's biomarkers were found: 5OH-MEHP+5oxo-MEHP (β = 2.56; 95% CI 0.58-4.55; N = 270), 5OH-MEHP+5cx-MEPP (β = 2.48; 95% CI 0.47-4.49; N = 270) and 5OH-MEHP (β = 2.58; 95% CI 0.65-4.51; N = 270). On the contrary, in the OCC the relation between DEHP's biomarkers and FSIQ tended to be inverse but imprecise (p-value ≥ 0.10). No associations were found in the PCB cohort. FSIQ was not associated with HEXAMOLL® DINCH in any cohort. In conclusion, these results do not provide evidence of an association between concurrent phthalate/DINCHHEXAMOLLR DINCH exposure and IQ in children.This work received external funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No. 733032 [“European Human Biomonitoring Initiative” (HBM4EU)] and received co-funding from the author’s organizations.

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis
BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Evaluating the SERCA2 and VEGF mRNAs as Potential Molecular Biomarkers of the Onset and Progression in Huntington's Disease
Abnormalities of intracellular Ca2+ homeostasis and signalling as well as the down-regulation
of neurotrophic factors in several areas of the central nervous system and in peripheral
tissues are hallmarks of Huntington\u2019s disease (HD). As there is no therapy for this hereditary,
neurodegenerative fatal disease, further effort should be made to slow the progression
of neurodegeneration in patients through the definition of early therapeutic interventions.
For this purpose, molecular biomarker(s) for monitoring disease onset and/or progression
and response to treatment need to be identified. In the attempt to contribute to the research
of peripheral candidate biomarkers in HD, we adopted a multiplex real-time PCR approach
to analyse the mRNA level of targeted genes involved in the control of cellular calcium homeostasis
and in neuroprotection. For this purpose we recruited a total of 110 subjects possessing
the HD mutation at different clinical stages of the disease and 54 sex- and agematched
controls. This study provides evidence of reduced transcript levels of sarco-endoplasmic
reticulum-associated ATP2A2 calcium pump (SERCA2) and vascular endothelial
growth factor (VEGF) in peripheral blood mononuclear cells (PBMCs) of manifest and premanifest
HD subjects. Our results provide a potentially new candidate molecular biomarker
for monitoring the progression of this disease and contribute to understanding some early
events that might have a role in triggering cellular dysfunctions in HD
Evolving trends in the management of acute appendicitis during COVID-19 waves. The ACIE appy II study
Background: In 2020, ACIE Appy study showed that COVID-19 pandemic heavily affected the management of patients with acute appendicitis (AA) worldwide, with an increased rate of non-operative management (NOM) strategies and a trend toward open surgery due to concern of virus transmission by laparoscopy and controversial recommendations on this issue. The aim of this study was to survey again the same group of surgeons to assess if any difference in management attitudes of AA had occurred in the later stages of the outbreak.
Methods: From August 15 to September 30, 2021, an online questionnaire was sent to all 709 participants of the ACIE Appy study. The questionnaire included questions on personal protective equipment (PPE), local policies and screening for SARS-CoV-2 infection, NOM, surgical approach and disease presentations in 2021. The results were compared with the results from the previous study.
Results: A total of 476 answers were collected (response rate 67.1%). Screening policies were significatively improved with most patients screened regardless of symptoms (89.5% vs. 37.4%) with PCR and antigenic test as the preferred test (74.1% vs. 26.3%). More patients tested positive before surgery and commercial systems were the preferred ones to filter smoke plumes during laparoscopy. Laparoscopic appendicectomy was the first option in the treatment of AA, with a declined use of NOM.
Conclusion: Management of AA has improved in the last waves of pandemic. Increased evidence regarding SARS-COV-2 infection along with a timely healthcare systems response has been translated into tailored attitudes and a better care for patients with AA worldwide
New insights into the genetic etiology of Alzheimer's disease and related dementias
Characterization of the genetic landscape of Alzheimer's disease (AD) and related dementias (ADD) provides a unique opportunity for a better understanding of the associated pathophysiological processes. We performed a two-stage genome-wide association study totaling 111,326 clinically diagnosed/'proxy' AD cases and 677,663 controls. We found 75 risk loci, of which 42 were new at the time of analysis. Pathway enrichment analyses confirmed the involvement of amyloid/tau pathways and highlighted microglia implication. Gene prioritization in the new loci identified 31 genes that were suggestive of new genetically associated processes, including the tumor necrosis factor alpha pathway through the linear ubiquitin chain assembly complex. We also built a new genetic risk score associated with the risk of future AD/dementia or progression from mild cognitive impairment to AD/dementia. The improvement in prediction led to a 1.6- to 1.9-fold increase in AD risk from the lowest to the highest decile, in addition to effects of age and the APOE ε4 allele
