Journal article (peer-reviewed)abstract
- Background: We aimed to examine whether using a high fraction of inspired oxygen (FIO2) in the context of an individualised intra- and postoperative open-lung ventilation approach could decrease surgical site infection (SSI) in patients scheduled for abdominal surgery. Methods: We performed a multicentre, randomised controlled clinical trial in a network of 21 university hospitals from June 6, 2017 to July 19, 2018. Patients undergoing abdominal surgery were randomly assigned to receive a high (0.80) or conventional (0.3) FIO2 during the intraoperative period and during the first 3 postoperative hours. All patients were mechanically ventilated with an open-lung strategy, which included recruitment manoeuvres and individualised positive end-expiratory pressure for the best respiratory-system compliance, and individualised continuous postoperative airway pressure for adequate peripheral oxyhaemoglobin saturation. The primary outcome was the prevalence of SSI within the first 7 postoperative days. The secondary outcomes were composites of systemic complications, length of intensive care and hospital stay, and 6-month mortality. Results: We enrolled 740 subjects: 371 in the high FIO2 group and 369 in the low FIO2 group. Data from 717 subjects were available for final analysis. The rate of SSI during the first postoperative week did not differ between high (8.9%) and low (9.4%) FIO2 groups (relative risk [RR]: 0.94; 95% confidence interval [CI]: 0.59-1.50; P=0.90]). Secondary outcomes, such as atelectasis (7.7% vs 9.8%; RR: 0.77; 95% CI: 0.48-1.25; P=0.38) and myocardial ischaemia (0.6% [n=2] vs 0% [n=0]; P=0.47) did not differ between groups. Conclusions: An oxygenation strategy using high FIO2 compared with conventional FIO2 did not reduce postoperative SSIs in abdominal surgery. No differences in secondary outcomes or adverse events were found.

Journal article (peer-reviewed)abstract
- Objective: The aim of this clinical trial is to examine whether it is possible to reduce postoperative complications using an individualized perioperative ventilatory strategy versus using a standard lung-protective ventilation strategy in patients scheduled for thoracic surgery requiring one-lung ventilation. Design: International, multicenter, prospective, randomized controlled clinical trial. Setting: A network of university hospitals. Participants: The study comprises 1,380 patients scheduled for thoracic surgery. Interventions: The individualized group will receive intraoperative recruitment maneuvers followed by individualized positive end-expiratory pressure (open lung approach) during the intraoperative period plus postoperative ventilatory support with high-flow nasal cannula, whereas the control group will be managed with conventional lung-protective ventilation. Measurements and Main Results: Individual and total number of postoperative complications, including atelectasis, pneumothorax, pleural effusion, pneumonia, acute lung injury; unplanned readmission and reintubation; length of stay and death in the critical care unit and in the hospital will be analyzed for both groups. The authors hypothesize that the intraoperative application of an open lung approach followed by an individual indication of high-flow nasal cannula in the postoperative period will reduce pulmonary complications and length of hospital stay in high-risk surgical patients.

APOE -ε4 modulates the association between regional amyloid deposition and cognitive performance in cognitively unimpaired middle-aged individuals
- 2023

In: EJNMMI Research. - : Springer Science and Business Media LLC. - 2191-219X. ; 13:1
-
Journal article (peer-reviewed)abstract
- Purpose: To determine whether the APOE-ε4 allele modulates the relationship between regional β-amyloid (Aβ) accumulation and cognitive change in middle-aged cognitively unimpaired (CU) participants. Methods: The 352 CU participants (mean aged 61.1 [4.7] years) included completed two cognitive assessments (average interval 3.34 years), underwent [18F]flutemetamol Aβ positron emission tomography (PET), T1w magnetic resonance imaging (MRI), as well as APOE genotyping. Global and regional Aβ PET positivity was assessed across five regions-of-interest by visual reading (VR) and regional Centiloids. Linear regression models were developed to examine the interaction between regional and global Aβ PET positivity and APOE-ε4 status on longitudinal cognitive change assessed with the Preclinical Alzheimer’s Cognitive Composite (PACC), episodic memory, and executive function, after controlling for age, sex, education, cognitive baseline scores, and hippocampal volume. Results: In total, 57 participants (16.2%) were VR+ of whom 41 (71.9%) were APOE-ε4 carriers. No significant APOE-ε4*global Aβ PET interactions were associated with cognitive change for any cognitive test. However, APOE-ε4 carriers who were VR+ in temporal areas (n = 19 [9.81%], p = 0.04) and in the striatum (n = 8 [4.14%], p = 0.01) exhibited a higher decline in the PACC. The temporal areas findings were replicated when regional PET positivity was determined with Centiloid values. Regionally, VR+ in the striatum was associated with higher memory decline. As for executive function, interactions between APOE-ε4 and regional VR+ were found in temporal and parietal regions, and in the striatum. Conclusion: CU APOE-ε4 carriers with a positive Aβ PET VR in regions known to accumulate amyloid at later stages of the Alzheimer’s disease (AD) continuum exhibited a steeper cognitive decline. This work supports the contention that regional VR of Aβ PET might convey prognostic information about future cognitive decline in individuals at higher risk of developing AD.

Journal article (peer-reviewed)abstract
- Aim To identify the most important reasons for selecting a particular route of heroin administration and for subsequent transitions during a period of epidemic HIV transmission. To study temporal trends in these reasons.Design Cross-sectional survey.Participants Nine hundred heroin users in three Spanish cities: 305 in Seville, 297 in Madrid and 298 in Barcelona.Measurements A separate analysis was made of the reasons for five types of behaviour: (a) selecting injection as the initial usual route of heroin administration (URHA); (b) changing the URHA to injection; (c) never having injected drugs; (d) selecting the smoked or sniffed route as the initial URHA; and (e) changing the URHA to a non-injected route. Subjects were invited to evaluate the importance of each reason included in a closed list. Spontaneously self-perceived reasons were also explored in an open-ended question for each of the five types of behaviour studied.Findings The primary reason selected for each type of behaviour was: (a) pressure of the social environment; (b) belief that injection is a more efficient route than smoking or sniffing heroin; (c) concern about health consequences (especially fears of HIV and overdose), and fear of blood or of sticking a needle into one's veins; (d), pressure of the social environment and (e) concern about health consequences and vein problems. For women, having a sexual partner who injected heroin played a decisive role in initiating or changing to injection. Few people spontaneously mentioned market conditions for purchasing heroin as an important reason for any behaviour, nor did many mention risk of overdose as reasons for (c) or (d).Conclusions These findings should be considered when designing interventions aimed at preventing initiation of injecting or facilitating the transition to non-injected routes.

Research review (peer-reviewed)abstract
- © 2017, The Author(s). Introduction: With the goal of generate uniform criteria among centers dealing with pituitary tumors and to enhance patient care, the Pituitary Society decided to generate criteria for developing Pituitary Tumors Centers of Excellence (PTCOE). Methods: To develop that task, a group of ten experts served as a Task Force and through two years of iterative work an initial draft was elaborated. This draft was discussed, modified and finally approved by the Board of Directors of the Pituitary Society. Such document was presented and debated at a specific session of the Congress of the Pituitary Society, Orlando 2017, and suggestions were incorporated. Finally the document was distributed to a large group of global experts that introduced further modifications with final endorsement. Results: After five years of iterative work a document with the ideal criteria for a PTCOE is presented. Conclusions: Acknowledging that very few centers in the world, if any, likely fulfill the requirements here presented, the document may be a tool to guide improvements of care delivery to patients with pituitary disorders. All these criteria must be accommodated to the regulations and organization of Health of a given country.

Financial Regulation Debates in Hard Times: A Comparative Analysis of Insider and Outsider Pressure during the Global Financial Crisis
- 2020
-
In: Journal of Comparative Policy Analysis: Research and Practice. - : Informa UK Limited. - 1387-6988 .- 1572-5448.
-
Journal article (peer-reviewed)abstract
- This article analyses the nature of policy debates on financial regulation during the onset of the Global Financial Crisis (GFC) by considering three elements that shape them: the salience of the debate, the actors that dominate the debate, and the degree of anti-status quo pressure. Theoretically, it contributes to Culpepper’s quiet/noisy politics framework by clarifying its multidimensionality and explicitly introducing the degree of contestation. Empirically, it focuses on two regulatory issues: (1) the restriction of banking and financial activities and (2) the debate on the remuneration of bankers. The data captures political claims during the first 12 months of the GFC and covers 19 established democracies. The findings indicate that policy debates were unevenly politicized across countries and issues, and that structural factors are not enough to account for the observed variation in pressure for reform for all types of actors, thus constituting a puzzle for further research.
