Abstract
A 3D printed device covered with Zn/Co-ZIF-derived carbon allows the on-site extraction of fluoroquinolones (FQs) from wastewater, avoiding the sample transportation to the laboratory, and the subsequent elution, separation and determination using an on-line flow system based on sequential injection analysis (SIA) coupled to HPLC-FL. Several parameters that affect the extraction efficiency and desorption were optimized including the sorption phase immobilization technique on the 3D device, extraction time, pH effect, sample volume as well as the type of eluent, eluent volume, and flow rate. Under optimum conditions, detection limits of 3-9 ng L-1 were achieved for norfloxacin, ciprofloxacin, danofloxacin, enrofloxacin and difloxacin. The precision expressed as relative standard deviation (%RSD, n = 3), showed intraday and interday ranges of 1.5-5.3% and 2.8-5.7%, respectively, demonstrating a good precision of the proposed methodology. To assess matrix effects and accuracy of the proposed method in real samples, recovery studies were performed without and with FQs spiked at different concentrations (0.5-10 μg L-1) to wastewater samples, showing good recoveries in the range of 91-104%. The results allow to confirm the applicability of MOF-derived carbons as adsorbents for on-site extraction, and the satisfactory separation and quantification of FQs by a SIA-HPLC-FL on-line system after their desorption with small eluent volumes.

Abstract
PURPOSE To explore trans men's access and use of healthcare services in Chile, based on the experiences of the trans men themselves, as well as of healthcare professionals. METHODS A qualitative study with an ethnographic approach was carried out with 30 participants: 14 trans men and 16 healthcare professionals. Semi-structured one-on-one interviews with open-ended questions were used to collect the data. A thematic analysis was carried out with the NVivo Software. RESULTS Three main themes were identified: (1) failures in the recognition of trans identity, (2) challenges with patient-centered care, and (3) use of other ("non-trans") health services. CONCLUSIONS The results suggest that not all transition processes are the same, individuals seek different ways; therefore, it is necessary to consider different body types and identities when planning programs and care for men in transition. Moreover, the accompaniment provided during the gender transition process should contemplate emotional and mental support. CLINICAL RELEVANCE The study outlines the need for all healthcare professionals to have training and knowledge about the transgender population, regardless of whether they are part of the teams supporting gender transition processes. The role of nurses and the contributions that can be made from nursing discipline in this research field are fundamental.

Abstract
In response to COVID-19 pandemic, we have launched a vaccine development program against SARS-CoV-2. Here we report the safety, tolerability, and immunogenicity of a recombinant protein RBD fusion heterodimeric vaccine against SARS-CoV-2 (PHH-1V) evaluated in a phase 1-2a dose-escalation, randomized clinical trial conducted in Catalonia, Spain. 30 young healthy adults were enrolled and received two intramuscular doses, 21 days apart of PHH-1V vaccine formulations [10 µg (n = 5), 20 µg (n = 10), 40 µg (n = 10)] or control [BNT162b2 (n = 5)]. Each PHH-1V group had one safety sentinel and the remaining participants were randomly assigned. The primary endpoint was solicited events within 7 days and unsolicited events within 28 days after each vaccination. Secondary endpoints were humoral and cellular immunogenicity against the variants of concern (VOCs) alpha, beta, delta and gamma. All formulations were safe and well tolerated, with tenderness and pain at the site of injection being the most frequently reported solicited events. Throughout the study, all participants reported having at least one mild to moderate unsolicited event. Two unrelated severe adverse events (AE) were reported and fully resolved. No AE of special interest was reported. Fourteen days after the second vaccine dose, all participants had a >4-fold change in total binding antibodies from baseline. PHH-1V induced robust humoral responses with neutralizing activities against all VOCs assessed (geometric mean fold rise at 35 days p < 0.0001). The specific T-cell response assessed by ELISpot was moderate. This initial evaluation has contributed significantly to the further development of PHH-1V, which is now included in the European vaccine portfolio.ClinicalTrials.gov Identifier NCT05007509EudraCT No. 2021-001411-82.

Abstract
The continuing high global incidence of COVID-19 and the undervaccinated status of billions of persons strongly motivate the development of a new generation of efficacious vaccines. We have developed an adjuvanted vaccine candidate, PHH-1V, based on a protein comprising the receptor binding domain (RBD) of the Beta variant of SARS-CoV-2 fused in tandem with the equivalent domain of the Alpha variant, with its immunogenicity, safety and efficacy previously demonstrated in mouse models. In the present study, we immunized pigs with different doses of PHH-1V in a prime-and-boost scheme showing PHH-1V to exhibit an excellent safety profile in pigs and to produce a solid RBD-specific humoral response with neutralising antibodies to 7 distinct SARS-CoV-2 variants of concern, with the induction of a significant IFNγ+ T-cell response. We conclude that PHH-1V is safe and elicits a robust immune response to SARS-CoV-2 in pigs, a large animal preclinical model.

Abstract
SARS-CoV-2 emerged in December 2019 and quickly spread worldwide, continuously striking with an unpredictable evolution. Despite the success in vaccine production and mass vaccination programs, the situation is not still completely controlled, and therefore accessible second-generation vaccines are required to mitigate the pandemic. We previously developed an adjuvanted vaccine candidate coded PHH-1V, based on a heterodimer fusion protein comprising the RBD domain of two SARS-CoV-2 variants. Here, we report data on the efficacy, safety, and immunogenicity of PHH-1V in cynomolgus macaques. PHH-1V prime-boost vaccination induces high levels of RBD-specific IgG binding and neutralizing antibodies against several SARS-CoV-2 variants, as well as a balanced Th1/Th2 cellular immune response. Remarkably, PHH-1V vaccination prevents SARS-CoV-2 replication in the lower respiratory tract and significantly reduces viral load in the upper respiratory tract after an experimental infection. These results highlight the potential use of the PHH-1V vaccine in humans, currently undergoing Phase III clinical trials.

Abstract
Feline leukemia virus (FeLV) is one of the most prevalent infectious diseases in domestic cats. Although different commercial vaccines are available, none of them provides full protection. Thus, efforts to design a more efficient vaccine are needed. Our group has successfully engineered HIV-1 Gag-based VLPs that induce a potent and functional immune response against the HIV-1 transmembrane protein gp41. Here, we propose to use this concept to generate FeLV-Gag-based VLPs as a novel vaccine strategy against this retrovirus. By analogy to our HIV-1 platform, a fragment of the FeLV transmembrane p15E protein was exposed on FeLV-Gag-based VLPs. After optimization of Gag sequences, the immunogenicity of the selected candidates was evaluated in C57BL/6 and BALB/c mice, showing strong cellular and humoral responses to Gag but failing to generate anti-p15E antibodies. Altogether, this study not only tests the versatility of the enveloped VLP-based vaccine platform but also sheds light on FeLV vaccine research.

Abstract
Background A SARS-CoV-2 protein-based heterodimer vaccine, PHH-1V, has been shown to be safe and well-tolerated in healthy young adults in a first-in-human, Phase I/IIa study dose-escalation trial. Here, we report the interim results of the Phase IIb HH-2, where the immunogenicity and safety of a heterologous booster with PHH-1V is assessed versus a homologous booster with BNT162b2 at 14, 28 and 98 days after vaccine administration. Methods The HH-2 study is an ongoing multicentre, randomised, active-controlled, double-blind, non-inferiority Phase IIb trial, where participants 18 years or older who had received two doses of BNT162b2 were randomly assigned in a 2:1 ratio to receive a booster dose of vaccine-either heterologous (PHH-1V group) or homologous (BNT162b2 group)-in 10 centres in Spain. Eligible subjects were allocated to treatment stratified by age group (18-64 versus ≥65 years) with approximately 10% of the sample enrolled in the older age group. The primary endpoints were humoral immunogenicity measured by changes in levels of neutralizing antibodies (PBNA) against the ancestral Wuhan-Hu-1 strain after the PHH-1V or the BNT162b2 boost, and the safety and tolerability of PHH-1V as a boost. The secondary endpoints were to compare changes in levels of neutralizing antibodies against different variants of SARS-CoV-2 and the T-cell responses towards the SARS-CoV-2 spike glycoprotein peptides. The exploratory endpoint was to assess the number of subjects with SARS-CoV-2 infections ≥14 days after PHH-1V booster. This study is ongoing and is registered with ClinicalTrials.gov, NCT05142553. Findings From 15 November 2021, 782 adults were randomly assigned to PHH-1V (n = 522) or BNT162b2 (n = 260) boost vaccine groups. The geometric mean titre (GMT) ratio of neutralizing antibodies on days 14, 28 and 98, shown as BNT162b2 active control versus PHH-1V, was, respectively, 1.68 (p < 0.0001), 1.31 (p = 0.0007) and 0.86 (p = 0.40) for the ancestral Wuhan-Hu-1 strain; 0.62 (p < 0.0001), 0.65 (p < 0.0001) and 0.56 (p = 0.003) for the Beta variant; 1.01 (p = 0.92), 0.88 (p = 0.11) and 0.52 (p = 0.0003) for the Delta variant; and 0.59 (p ≤ 0.0001), 0.66 (p < 0.0001) and 0.57 (p = 0.0028) for the Omicron BA.1 variant. Additionally, PHH-1V as a booster dose induced a significant increase of CD4+ and CD8+ T-cells expressing IFN-γ on day 14. There were 458 participants who experienced at least one adverse event (89.3%) in the PHH-1V and 238 (94.4%) in the BNT162b2 group. The most frequent adverse events were injection site pain (79.7% and 89.3%), fatigue (27.5% and 42.1%) and headache (31.2 and 40.1%) for the PHH-1V and the BNT162b2 groups, respectively. A total of 52 COVID-19 cases occurred from day 14 post-vaccination (10.14%) for the PHH-1V group and 30 (11.90%) for the BNT162b2 group (p = 0.45), and none of the subjects developed severe COVID-19. Interpretation Our interim results from the Phase IIb HH-2 trial show that PHH-1V as a heterologous booster vaccine, when compared to BNT162b2, although it does not reach a non-inferior neutralizing antibody response against the Wuhan-Hu-1 strain at days 14 and 28 after vaccination, it does so at day 98. PHH-1V as a heterologous booster elicits a superior neutralizing antibody response against the previous circulating Beta and the currently circulating Omicron BA.1 SARS-CoV-2 variants in all time points assessed, and for the Delta variant on day 98 as well. Moreover, the PHH-1V boost also induces a strong and balanced T-cell response. Concerning the safety profile, subjects in the PHH-1V group report significantly fewer adverse events than those in the BNT162b2 group, most of mild intensity, and both vaccine groups present comparable COVID-19 breakthrough cases, none of them severe.

Abstract
236 Background: Alterations on the tumor suppressor genes (TSG) RB1, PTEN and TP53 are associated with treatment resistance and aggressive clinical evolution of prostate cancer patients (pts). We developed and assessed the role of a TSG gene expression signature in mHSPC pts. Methods: This is a multicenter retrospective biomarker study in mHSPC pts receiving different therapies. RB1, PTEN and TP53 mutations were assessed by targeted sequencing and its gene expression was determined by the nCounter platform in FFPE tumor samples. Normalized and transformed (z-score) expression data of a training cohort was used to establish the cut-off for RB1, PTEN and TP53 expression, those cut-offs were then applied to the other cohorts. TSGlow was considered when ≥2 out of 3 TSG presented low expression, and TSGwt in the remaining cases. TSG signature was correlated with castration resistance-free survival (CRPC-FS) (primary endpoint) and overall survival (OS) by Kaplan Meier and multivariate Cox analysis. Results: Overall, 297 pts (baseline characteristics are shown) were included: 125 treated with ADT+Docetaxel (ADT+D) (54 and 71 in training and validation cohorts, respectively), 93 with ADT, and 79 with ADT+Abiraterone or Enzalutamide (ADT+A/E). Training cohort pts were tested for both, gene expression and targeted sequencing of TSG. Pts with low expression of PTEN showed higher frequency of PTEN mutations (p<0.05). TSGlow (14 (25.9%) out of 54 pts) had a worse CRPC-FS (14.3 vs. 21.7 months (m); HR 2.2 (95% CI, 1.1 - 4.4), p=0.022). In the validation cohort, 7 (9.9%) pts were TSGlow and had a worse CPRC-FS (11.7 vs. 20 m, HR 2.5 (95% CI, 1.1 - 5.5), p=0.027) and OS (27.6 vs 58.1 m, HR 3.5 (95% CI, 1.3 - 9.5) p=0.012). TSGlow signature was independently associated with CPRC-FS (HR 2.66 (95% CI, 1.17 - 6.06), p=0.02) and OS (HR 3.67 (95% CI, 1.33 - 10.10), p=0.012). In the ADT and ADT+A/E cohorts, 20 (21.5%) and 14 (17.7%) pts were TSGlow, respectively. TSGlow was not predictive of either CRPC-FS (p=0.23 and p=0.242, respectively) or OS (p=0.091 and p=0.66, respectively). We analyzed together high-volume pts from both ADT+D and ADT cohorts. TSGlow pts (16, 10.74%) treated with ADT+D had a CRPC-FS (13.6 m) similar to pts treated with ADT (TSGlow = 14.5 m and TSGwt = 12.8 m). Moreover, TSGwt pts treated with ADT+D had a better CRPC-FS (19.3m) (p=0.022) and OS (ADT/TSGlow = 31.7 m, ADT/TSGwt = 38.6 m, ADT+D/TSGlow = 31.5 m, ADT+D/TSGwt = 52.2 m, p=0.07). Conclusions: A TSG gene expression signature is predictive of taxanes benefit in mHSPC pts and may be useful to personalize the treatment in this setting. [Table: see text]

Abstract
BACKGROUND Hereditary angioedema with C1 inhibitor deficiency (HAE-C1INH) is a rare disease characterized by swelling episodes. It affects quality of life (QoL) and can be lethal, when involving upper airways. Treatment is individualized, with therapeutic options including on-demand treatment (ODT), and short- and long-term prophylaxis (STP, LTP). However, available guidelines are not always clear about treatment selection, its goals or assessment of goal achievement. OBJECTIVE To review the available evidence for the management of HAE-C1INH and build a Spanish expert consensus to steer HAE-C1INH management towards a treat-to-target (T2T) approach, while addressing some of the unclear aspects of the Spanish guidelines. METHODS We reviewed the literature on the management of HAE-C1INH with a T2T approach, focusing on: 1) treatment selection and goals; and 2) available tools to assess goal achievement. We discussed the literature based on clinical experience and drew up 45 statements on undefined management aspects. A panel of 53 HAE experts validated the statements through a two-round Delphi process. RESULTS The goals for ODT and STP are minimizing the morbidity and mortality of attacks, and preventing attacks caused by known triggers, respectively, while the main goal of LTP is to decrease the rate, severity and duration of attacks. Furthermore, when prescribing, clinicians should consider the reduction in adverse events, while increasing patient QoL and satisfaction. Appropriate instruments for assessing goal achievement have also been indicated. CONCLUSIONS We provide recommendations on previously unclear aspects of HAE-C1INH management with ODT, STP and LTP, focusing particularly on clinical and patient-oriented goals.

Abstract
Current COVID-19 vaccines have been associated with a decline in infection rates, prevention of severe disease, and a decrease in mortality rates. However, SARS-CoV-2 variants are continuously evolving, and development of new accessible COVID-19 vaccines is essential to mitigate the pandemic. Here, we present data on preclinical studies in mice of a receptor-binding domain (RBD)-based recombinant protein vaccine (PHH-1V) consisting of an RBD fusion heterodimer comprising the B.1.351 and B.1.1.7 SARS-CoV-2 variants formulated in SQBA adjuvant, an oil-in-water emulsion. A prime-boost immunisation with PHH-1V in BALB/c and K18-hACE2 mice induced a CD4+ and CD8+ T cell response and RBD-binding antibodies with neutralizing activity against several variants, and also showed a good tolerability profile. Significantly, RBD fusion heterodimer vaccination conferred 100% efficacy, preventing mortality in SARS-CoV-2 infected K18-hACE2 mice, but also reducing Beta, Delta and Omicron infection in lower respiratory airways. These findings demonstrate the feasibility of this recombinant vaccine strategy.

Abstract
BACKGROUND Recent guidelines recommend establishing a local reference interval (RI) for thyroid function. We aimed to establish trimester-specific RIs for thyrotropin (TSH) and free thyroxine (FT4) in a cohort of healthy pregnant women in Catalonia (Spain). METHODS A prospective observational study was conducted with 332 healthy pregnant women, from the first trimester (1T) to delivery. TSH was measured using an Architect® immunoassay (Abbott) and FT4 by two immunoassays, Architect® (Abbott) and Cobas® (Roche), in the three trimesters. FT4 was also measured by liquid chromatography mass spectrometry (LC/MS/MS) in the 1T. RESULTS TSH (µUI/mL) increased throughout pregnancy (1T: 0.03-3.78; 2T: 0.51-3.53; 3T: 0.50-4.32; p < 0.0001) and FT4 (pmol/L) progressively decreased (Architect® 1T: 10.42-15.96; 2T: 8.37-12.74; 3T: 8.24-12.49; p < 0.0001; and Cobas®: 1T: 11.46-19.05; 2T: 9.65-14.67; 3T: 8.88-14.54; p < 0.0067). The FT4 RI during 1T determined LC/MS/MS was 8.75-18.27. Despite the 1T FT4 results measured by LC/MS/MS and with the two immunoassays being significantly correlated, the results obtained by the three methods were found to be non-interchangeable. CONCLUSIONS We established trimester-specific RIs for TSH and for FT4 with immunoassays in our population. We also validated the 1T FT4 using LC/MS/MS to confirm the results of FT4 lower than the 2.5th percentile or higher than the 97.5th percentile.

Abstract
The presence of artificial and natural radioactivity in the environment is currently a topic of great relevance and ecological interest, even in human health issue, due to the increase of different anthropogenic activities. The use of multicommuted flow analysis techniques (e.g. Multi-Syringe Flow Injection Analysis - MSFIA, Lab-On-Valve - LOV and Lab-In-Syringe - LIS) has allowed the automation of radiochemical procedures to separate and preconcentrate radionuclides in environmental and biological samples. In comparison with the manual approach commonly used in routine analysis for radioactivity monitoring, the automation has enabled the development of highly reproducible methodologies with a great analysis frequency. Moreover, during the analytical procedure, the intervention of the analyst is drastically reduced, minimizing the radiological risk. The automation also offers significant advantages such as minimum consumption of time and reagents, reducing the cost and the generation of waste, contributing to the green chemistry. In this review, several multicommuted flow analysis techniques (MSFIA, LOV and LIS) reported in the last decade applied for the development of automatic sample treatment methodologies, used to separate, preconcentrate and quantify 90Sr, 99Tc, natural U and 226Ra in biological and environmental samples are described and critically compared.

Abstract
165 Background: NE dedifferentiation is associated to clinical aggressiveness and resistance to androgen receptor inhibition in prostate cancer. We investigated impact of a NE expression signature in the clinical outcome of mCRPC patients treated with taxanes. Methods: This is a multicenter retrospective study. A customized panel of 45 NE-related gene signature was tested in total RNA from formalin-fixed paraffin-embedded hormone-sensitive tumor samples, by the nCounter platform (Nanostring Technologies). Patients were grouped according to their molecular profile by unsupervised clustering. Expression levels were correlated with taxanes response and clinical outcome. Independent association with survival was evaluated by multivariate Cox modeling. Results: Eighty seven patients were included in the study, 79 were treated with docetaxel and 8 with cabazitaxel. Median age was 64.8 (44-88.3) years and median follow-up was 20.7 (1.17-74.4) months. High expression of the NE signature was associated with a shorter time of CRPC development (N=60, median 12.8 vs 21.6, HR 2.4, 95%CI 1.3-4.3, P=0.003) and shorter OS from CRPC diagnosis (median 24.1 vs 41.33, HR 2.3, 95%CI 1.4-3.8, P=0.001). Moreover, according to the outcome to taxanes, high NE signature correlated with lower PSA-PFS (median 6.6 vs 10.1 mo P=0.047, HR 1.6, 95%CI 1-2.7, P=0.05) and OS (median 19 vs 22 mo, HR 1.8, 95%CI 1.1-2.8, P=0.014), and it was independently associated to a lower OS (HR 1.9, 95%CI 1.1-3.2, P=0.016). Conclusions: NE-related gene expression in hormone-sensitive tumor samples is associated with adverse clinical outcome and lower taxane benefit in metastatic CRPC patients. Thus, molecular characterization of primary tumors may be useful to guide treatment strategies in metastatic prostate cancer.

Abstract
BACKGROUND End-of-life (EOL) communication is crucial, particularly for cancer patients. While advanced care planning is still uncommon, we sought to investigate its impact on care intensity in case of organ failure in lung cancer patients. METHODS We prospectively included consecutive lung cancer patients hospitalised at the Grenoble University Hospital, France, between January 1, 2014 and March 31, 2016. Patients could be admitted several times and benefited from advanced care planning based on three care intensities: intensive care, maximal medical care, and exclusive palliative care. Patients' wishes were addressed. RESULTS Data of 739 hospitalisations concerning 482 patients were studied. During the three first admissions, 173 (25%) patients developed organ failure, with intensive care proposed to 56 (32%), maximal medical care to 104 (60%), and exclusive palliative care to 13 (8%). Median time to organ failure was 9 days [IQR 25%-75%: 3-13]. All patients benefited from care intensity that was either equal to or lower than the care proposed. Specific wishes were recorded for 158 (91%) patients, with a discussion about EOL conditions held in 116 (73%). CONCLUSIONS In case of organ failure, advanced care planning helps provide reasonable care intensity. The role of the patient's wishes as to the proposed care must be further investigated. CLINICAL TRIAL REGISTRATION The study was registered at www.ClinicalTrials.gov with the identifier NCT02852629.

Abstract
INTRODUCTION Immune-checkpoint inhibitors have been approved for first and second line treatments of metastatic non-small cell lung cancer based on the results of several phase III trials. Patients with organ transplantation were excluded from these studies because checkpoint inhibitors could activate allo-reactive T cells leading to acute graft rejection. CASE REPORT A 71-year-old Caucasian-male was diagnosed with stage IV pulmonary adenocarcinoma with multiple metastases, without molecular alteration and negative PD-L1 status. He had a left kidney transplant, and his immunosuppressive regimen consisted of sirolimus and mycophenolate mofetil. After failure of two therapeutic lines (carboplatin-paclitaxel and erlotinib) a multidisciplinary oncology meeting with the nephrologist started third line treatment with nivolumab 3mg/kg every 15 days, with no modification of the immunosuppressive treatment. The patient received a total of 14 injections of nivolumab with stable disease but treatment was discontinued due to acute rejection of the transplanted kidney 6 months later, without need for dialysis. The patient died of a chylothorax related to progression of the tumour 12 months after initiation of nivolumab. CONCLUSION Immune checkpoint inhibitors are a potential treatment for solid organ transplant patients despite the risk of graft rejection.

Abstract
HIV infection remains an important public health problem worldwide. The traditional preventive measures, such as sexual education, screening, and early antiretroviral treatment initiation, despite having shown their effectiveness, are not enough to control new infections. In this context, Pre-Exposure Prophylaxis (PrEP) has been investigated as a preventive measure. Currently, it has been extensively documented that the administration of antiretroviral treatment in an HIV exposed, but not infected population, could reduce the risk of transmission without significant drawbacks. Despite its high efficacy for HIV prevention, the use of PrEP remains a controversial measure, particularly its cost-effectiveness. For this reason, the access to PrEP is not available for all the HIV risk groups. Therefore, and based on the evidence found, the current approach must be the repercussions of not to implement PrEP, more than its cost or its effectiveness.

Abstract
BACKGROUND When patients with lung cancer present to the emergency department with organ failure the question of admission to intensive care has to be considered. Our aim is to describe the process leading to the proposed management. METHODS Retrospectively, all patients admitted to the emergency room between December 2010 and January 2015 with a diagnosis of ICD-10 C34.9 (lung cancer) were reviewed. Those with at least one organ failure were included. RESULTS The records of 561 patients were reviewed, 79 (14%) had at least one organ failure. The majority of these patients received maximal medical care (59%), 25% exclusive palliative care, and 15% intensive care. Performance status, metastatic status and efficacy of anti-tumor treatment were recorded in the emergency medical record in 20%, 66% and 74% of cases, respectively. An opinion was obtained from the oncologist in 44% of cases and from the intensivist in 41% of cases. No external advice was provided in 27% of cases. CONCLUSION In the majority of cases, the decision on the intensity of care to be provided to patients with lung cancer and organ failure was made in a collective manner.

Abstract
A 3D printed solid-phase extraction (SPE) device for uranium(VI) extraction has been fabricated using stereolithographic 3D printing. The 3D printed device is shaped as a stirred reactor chamber containing a network of small cubes, which were impregnated with TEVA resin for the extraction of U(VI) from water matrices without doing any previous pretreatment. A flow-through system was combined with off-line ICP-MS detection for the accurate and rapid determination of U(VI) at trace levels. The automatic system was satisfactorily optimized using experimental design, obtaining 0.03 and 0.09 ng U(VI) of detection and quantification limits, respectively, and a durability of 11 consecutive extractions. The reliability of the proposed system was confirmed through the analysis of a reference water material (CSN/CIEMAT 2011), and to water samples (tap, mineral and groundwater) by addition/recovery assays obtaining recoveries between 95 and 106%. This study present for the first time the design of a 3D printing SPE device impregnated with TEVA resin for the on-line extraction of U(VI), showing that 3D printing is a powerful tool for simplifying the construction of complex experimental devices and its operation in analytical procedures for pretreatment applications in water matrices.

Abstract
Le cancer bronchopulmonaire (CBP) est la première cause de mortalité par cancer en France et dans le monde, mais son pronostic tend à s’améliorer depuis une dizaine d’années grâce à de nouvelles classes de traitements : l’immunothérapie et les thérapies ciblées. L’immunothérapie stimule le système immunitaire afin d’engendrer une réponse antitumorale. Ces molécules peuvent être prescrites chez la plupart des patients avec un CBP non à petites cellules (CBNPC) métastatique et entraînent parfois des réponses tumorales majeures et durables pouvant dépasser les 24 mois. Toutefois, cette efficacité concerne entre 20 et 50 % des patients selon la ligne de traitement. Les thérapies ciblées sont des traitements oraux visant les cellules tumorales porteuses d’anomalies génétiques spécifiques (addictions oncogéniques) et intéressent moins de 15 % des patients avec CBNPC, majoritairement les non-fumeurs. Les deux principales sont les mutations du gène de l’epithelial growth factor receptor (EGFR) et les réarrangements d’anaplastic lymphoma kinase (ALK). Ces anomalies peuvent être diagnostiquées en quelques jours, parfois sur un prélèvement sanguin (biopsie liquide pour détecter les mutations EGFR). Les thérapies ciblées améliorent la survie globale des patients dont la médiane dépasse les 30 mois. Toutefois, ces deux classes de traitement entraînent des toxicités spécifiques, fréquentes mais souvent bénignes. Les hospitalisations en réanimation des patients porteurs de CBNPC sont croissantes. L’amélioration du pronostic de ces patients est à prendre en compte lors de la discussion d’admission en réanimation sans conduire à des prises en charge déraisonnables.

Abstract
Laser-based stereolithography (SLA) 3D printing has been applied to construct a 3D printed device as support for uranium(VI) extraction, using a quaternary ammonium salt in liquid and solid form. As proof of concept, a simple process was carried out to immobilize a selective and commercial resin (TEVA resin), in all the surface area of the non-cured SLA 3D printed device, becoming immobilized after UV photocuring. Besides, a coat of Aliquat®336 covering the surface of the cured SLA 3D printed device was tested. Both 3D printed devices as supported for liquid and solid extractant were characterized. Better results in terms of precision were obtained by using TEVA resin (RSD 2.9%), which was satisfactory optimized, reaching a LOD of 0.03 ng U(VI), and a durability of 10 consecutive extractions, maintaining a recovery of 90% with 5% RSD. The 3D printed device is able to preconcentrate up to a sample volume of 30 mL, without any additional pretreatment. The uranium detection was performed with an ICP-MS. Satisfactorily results were obtained analyzing reference material, e.g. phosphogypsum and water matrices from intercomparison exercises, at a confidence level of 95%.

Abstract
The use of functional fillers can be advantageous in terms of cost reduction and improved properties in plastics. There are many types of fillers used in industry, organic and inorganic, with a wide application area. As a response to the growing concerns about environmental damage that plastics cause, recently fillers have started to be considered as a way to reduce it by decreasing the need for petrochemical resources. Life cycle assessment (LCA) is identified as a proper tool to evaluate potential environmental impacts of products or systems. Therefore, in this study, the literature regarding LCA of plastics with functional fillers was reviewed in order to see if the use of fillers in plastics could be environmentally helpful. It was interesting to find out that environmental impacts of functional fillers in plastics had not been studied too often, especially in the case of inorganic fillers. Therefore, a gap in the literature was identified for the future works. Results of the study showed that, although there were not many and some differences exist among the LCA studies, the use of fillers in plastics industry may help to reduce environmental emissions. In addition, how LCA methodology was applied to these materials was also investigated.

Abstract
Alternative strategies are required to enhance the diagnosis of silent hepatitis C virus (HCV) infections in key populations at risk. Among them, HCV prevalence and bio-behavioural data are scarce for HIV-negative men who have sex with men (MSM) and men and trans-women sex workers. We sought to describe and assess the potential benefits of a community-based one-step HCV screening and confirmatory strategy for these populations in Barcelona. The screening strategy based on a real-time RT-PCR assay for HCV-RNA detection in dried-blood spots (DBS) was validated and implemented in addition to an antibody point-of-care test in a community centre. HCV prevalence was assessed, and bio-behavioural data were collected. The molecular assay was precise, reproducible, sensitive and specific. Four HIV-negative MSM reported being currently infected (0.75% HCV self-reported prevalence). Implementation of DBS testing was easy, and acceptability was >95%, but no silent HCV case was diagnosed (N = 580). High-risk sexual practices and drug use for sex were reported frequently. HIV prevalence was 4.7% in MSM and 10% in sex workers. Self-reported prevalence of other STIs ranged from 11.3% to 36.2%. In conclusion, HCV-RNA testing in DBS showed a good performance, but the assessed one-step strategy does not seem beneficial in this setting. Although no silent HCV infections were detected, the observed high-risk behaviours and prevalence of other STIs suggest that HCV spread should be periodically monitored among these populations in Barcelona by means of behavioural surveillance, rapid antibody testing and molecular confirmation in DBS.

Abstract
Leached fractions of U and Th from different environmental solid matrices were evaluated by an automatic system enabling the on-line lixiviation and extraction/pre-concentration of these two elements previous ICP-MS detection. UTEVA resin was used as selective extraction material. Ten leached fraction, using artificial rainwater (pH 5.4) as leaching agent, and a residual fraction were analyzed for each sample, allowing the study of behavior of U and Th in dynamic lixiviation conditions. Multivariate techniques have been employed for the efficient optimization of the independent variables that affect the lixiviation process. The system reached LODs of 0.1 and 0.7ngkg-1 of U and Th, respectively. The method was satisfactorily validated for three solid matrices, by the analysis of a soil reference material (IAEA-375), a certified sediment reference material (BCR- 320R) and a phosphogypsum reference material (MatControl CSN-CIEMAT 2008). Besides, environmental samples were analyzed, showing a similar behavior, i.e. the content of radionuclides decreases with the successive extractions. In all cases, the accumulative leached fraction of U and Th for different solid matrices studied (soil, sediment and phosphogypsum) were extremely low, up to 0.05% and 0.005% of U and Th, respectively. However, a great variability was observed in terms of mass concentration released, e.g. between 44 and 13,967ngUkg-1.

Abstract
OBJECTIVE Examine the prevalence of asthma and associated predictive factors in a group of 468 students. PATIENTS AND METHODS A descriptive, cross-sectional observational study in a randomly selected population of 468 children aged 10-12, in the city of Zaragoza. We used the ISAAC questionnaire on asthma completed by children under supervision of the investigators. We assessed the genetic risk (family history of asthma) and environmental risks. The risk for atopy was assessed by the presence of positive skin prick tests. RESULTS 25.3% of the children had symptoms consistent with asthma in the city of Zaragoza. Among them 33.1% reported a history of asthma in close relatives (OR=1.78, p<0.001). The history of hospitalisations for lower respiratory tract illness was strongly associated with the presence of asthma (OR=6.72, p<0.0001). Positive skin tests to Alternaria (OR=2.00, p<0.0001) and grass pollen (OR=1.76, p<0.001) were predictors of asthma. 63.6% of asthmatic children had presented clinical rhinitis in the previous 12 months, compared with 32% of non-asthmatics, and this difference was statistically significant (OR=3.89, p<0.0001). 47% of asthmatics presented with or previously had eczema, whereas only 26.9% of non-asthmatics presented with or previously had these types of lesions (p<0.0001). CONCLUSION The following are predictors of asthma: History of hospital admissions for lower respiratory tract illness, presence of rhinitis and/or eczema, positive prick test for certain aeroallergens, especially Alternaria and grass pollen, and family history of asthma.

Abstract
Measurements of airbone radionuclides (7)Be and gross beta (Aβ) jointly with atmospheric aerosols, i.e. particulate matter (PM) were routinely carried out for 10 years (2004-2014) at the University of the Balearic Islands, Spain. A total of 728 filter (0.8 μm pore size) samples were collected, and in all of them (7)Be and Aβ specific activities were detected. The maximum and minimum specific activities monitored were 0.73 ± 0.41 - 15.8 ± 1.26 mBq m(-3) of (7)Be and 0.14 ± 0.02 - 2.55 ± 0.04 mBq m(-3) of Aβ. PM concentrations were also determined, showing seasonal behavior with the highest concentration in summer and the lowest one in winter. Several meteorological parameters have been considered to explain this intra-annual variation. Principal component analysis (PCA) was applied to the dataset indicating that it is well represented by two principal components that explain 76.6% of total variance. Additionally, a second study with preliminary results of the specific activities of two natural radiotracers ((7)Be and (210)Pb) in PM10 samples was carried out. They were monitored for two years (2013-2015) in air of Mallorca Island. (7)Be and (210)Pb were detected in most of the PM10 filters, in 100% and 93% of them, respectively. The relationship between activities of both radionuclides and several relevant meteorological parameters was established at 95% confidence level. As a common result to PM and PM10 samples, a strong positive correlation between the evaluated radionuclides and temperature was found.
