Abstract
BACKGROUND & AIMS Hepatitis delta virus (HDV) is a satellite RNA virus that requires the hepatitis B virus (HBV) for assembly and propagation. Individuals infected with HDV progress to advanced liver disease faster than HBV-monoinfected individuals. Recent studies have estimated the global prevalence of anti-HDV antibodies among the HBV-infected population to be 5-15%. This study aimed to better understand HDV prevalence at the population level in 25 countries/territories. METHODS We conducted a literature review to determine the prevalence of anti-HDV and HDV RNA in hepatitis B surface antigen (HBsAg)-positive individuals in 25 countries/territories. Virtual meetings were held with experts from each setting to discuss the findings and collect unpublished data. Data were weighted for patient segments and regional heterogeneity to estimate the prevalence in the HBV-infected population. The findings were then combined with The Polaris Observatory HBV data to estimate the anti-HDV and HDV RNA prevalence in each country/territory at the population level. RESULTS After adjusting for geographical distribution, disease stage and special populations, the anti-HDV prevalence among the HBsAg+ population changed from the literature estimate in 19 countries. The highest anti-HDV prevalence was 60.1% in Mongolia. Once adjusted for the size of the HBsAg+ population and HDV RNA positivity rate, China had the highest absolute number of HDV RNA+ cases. CONCLUSIONS We found substantially lower HDV prevalence than previously reported, as prior meta-analyses primarily focused on studies conducted in groups/regions that have a higher probability of HBV infection: tertiary care centers, specific risk groups or geographical regions. There is large uncertainty in HDV prevalence estimates. The implementation of reflex testing would improve estimates, while also allowing earlier linkage to care for HDV RNA+ individuals. The logistical and economic burden of reflex testing on the health system would be limited, as only HBsAg+ cases would be screened. IMPACT AND IMPLICATIONS There is a great deal of uncertainty surrounding the prevalence of hepatitis delta virus among people living with hepatitis B virus at the population level. In this study, we aimed to better understand the burden in 25 countries and territories, to refine techniques that can be used in future analyses. We found a lower prevalence in the majority of places studied than had been previously reported. These data can help inform policy makers on the need to screen people living with hepatitis B virus to find those coinfected with hepatitis delta virus and at high risk of progression, while also highlighting the pitfalls that other researchers have often fallen into.

Abstract
Immunotherapy with immune checkpoint inhibitors (ICIs) has revolutionized advanced cancer management. Nevertheless, the generalized use of these medications has led to an increase in the incidence of adverse immune-mediated events and the liver is one of the most frequently affected organs. Liver involvement associated with the administration of immunotherapy is known as immune-mediated hepatitis (IMH), whose incidence and clinical characteristics have been described by different authors. It often presents as mild elevations of amino transferase levels, seen in routine blood tests, that spontaneously return to normal, but it can also manifest as severe transaminitis, possibly leading to the permanent discontinuation of treatment. The aim of the following review was to describe the most up-to-date concepts regarding the epidemiology, diagnosis, risk factors, and progression of IMH, as well as its incidence in different types of common cancers, including hepatocellular carcinoma. Treatment recommendations according to the most current guidelines are also provided.

Abstract
Recent years have seen concerted efforts to understand the relation between psoriasis and metabolic-associated fatty liver disease (MAFLD). Not only is MALFD diagnosed more often in patients with psoriasis, but its clinical course is also more aggressive. A common approach is therefore needed to enable early detection of liver disease coincident with psoriasis. Especially important is an analysis of risks and benefits of potentially hepatotoxic treatments. This consensus paper presents the recommendations of a group of experts in dermatology and hepatology regarding screening for MALFD as well as criteria for monitoring patients and referring them to hepatologists when liver disease is suspected.

Abstract
The oxidative potential (OP) of PM10 daily samples collected at a traffic site in southeastern Spain during summer and winter was assessed by two acellular assays: the ascorbic acid (AA) and dithiothreitol (DTT) methods. Although PM10 levels were similar during both periods, OP values (expressed in nmol min-1 m-3) showed a defined seasonal trend. The AA activity was higher in summer than in winter, whereas the DTT reactivity exhibited an opposite seasonal pattern. Both assays were sensitive to different PM10 components, as shown by the results of the linear correlation analysis. Moreover, the relationship between OP values and PM10 chemical species was not the same during summer and winter, indicating that particle toxicity is associated with different sources during the warm and cold seasons. When OP values were expressed on a mass basis (nmol min-1 µg-1), lower correlation coefficients with PM10 chemical species were generally obtained compared to volume-normalized activities. These outcomes suggest that only some specific components have a significant intrinsic oxidative potential.

Abstract
AIMS In recent years, major improvements in breast cancer treatments have led to a significant increase in survival. Despite that, this population's quality of life (QoL) information is lacking, especially real-world data. MATERIALS AND METHODS This was a prospective, multicentre, observational study of female breast cancer patients, without prior systemic treatment, treated between 2012 and 2019 in private health care in Brazil. QoL was assessed by two questionnaires, the EQ-5D-5L and the EORTC-QLQ-BR23. Additional data were retrospectively collected. RESULTS The study comprised 1372 patients, most with early-stage disease (80.2% stages 0-II). At a median follow-up of 25.6 months, the estimated 3-year overall survival was 93.6%. Patients with locally advanced and metastatic breast cancer had the lowest visual analogue scale scores and the highest symptom burden in all dimensions of EQ-5D-5L, but with the most significant improvement after treatment. With the EORTC-QLQ-BR23 questionnaire, patients undergoing lumpectomy had a better perception of body image. Axillary dissection led to greater arm symptoms after 12 months, radiotherapy enhanced breast symptoms and patients treated with chemotherapy had significant worsening in the effects of systemic therapy compared with endocrine or HER2 therapy. Staging and immunohistochemical subtype correlated with survival and with several QoL parameters, but overall survival was not independently affected by patient-reported outcomes in this cohort. CONCLUSION Our results show that early diagnosis and access to treatments with fewer side-effects, such as endocrine or targeted therapy, and less aggressive surgeries are the best strategies to achieve a better QoL for breast cancer patients.

Abstract
Water-soluble ions were analysed in size segregated aerosol samples collected in the port of Alicante (Southeastern Spain) during summer and winter using a multistage cascade impactor. Seasonal variations in the size distributions of the analysed components and the influence of bulk materials handling (loading/unloading and stockpiling) at the docks were investigated. The size distributions of SO42-, NH4+ and K+ were characterized by prominent peaks in the condensation and droplet modes, both in summer and winter, while those of Ca2+, Na+, Mg2+ and Cl- had a main peak centred at ∼4 μm. Although oxalate size distributions were similar during both seasons, the fraction of coarse-mode oxalate increased in summer most likely as a result of volatilization and repartition processes or reactions of oxalic acid with coarse alkaline particles. Nitrate size distributions were dominated by a coarse mode; however, during winter, modal peaks in the submicron size range were also observed due to favourable conditions for the formation of fine-mode NH4NO3. Harbour activities had a significant impact only on the concentrations of calcium, particularly in the coarse fraction, during both summer and winter.

Abstract
Abstract
Study question
Should we consider embryo quality as one of the most important criteria to follow when transferring a mosaic embryo?
Summary answer
Embryo quality is an implantation biomarker both for euploid and mosaic embryos, and also a determinant for selecting the most eligible mosaic for transfer.
What is known already
Several studies show the benefit of transferring mosaic embryos when there are no euploid embryos to transfer, and they still result in ongoing pregnancies and what is more important is that they result in healthy babies.
Studies and guidelines suggest prioritizing mosaic embryos based on maternal age, chromosomes impacted, percentage of aneuploidy, number of chromosomes involved, type of mosaic (simple vs complex, segmental vs complete, monosomy vs trisomy) but embryo quality is never part of these criteria.
Studies claim that mosaic implantation rate is lower than euploid embryos, but they never show if both populations are comparable in terms of quality.
Study design, size, duration
This is a retrospective observational study performed in a private centre between February 2018 and January 2020. The study includes the data analysis of 96 euploid blastocysts and 14 low risk mosaic blastocysts (defining low risk regarding chromosome syndromes and less than 50% level mosaicism). All transferred in single embryo transfer (SET) to 105 patients after PGT-A (mean maternal age 38,9 years).
The SET factor enables us to track the implantation outcome of all embryos.
Participants/materials, setting, methods
PGT-A with NGS technology was offered to patients of advanced maternal age and/or with repeated IVF failures. Trophectoderm biopsies were performed on day 5 and/or day 6 embryos, with laser assistance. Blastocyst morphology was scored in 3 groups: A: excellent (AA, AB, BA), B: good (BB), C: average and poor-quality embryos (BC, CB, CC). (Gardner-Schoolcraft classification)
Low risk mosaic embryo transfer was offered to patients with no euploid embryos to transfer.
Main results and the role of chance
We found no significant differences between both populations (euploid and mosaic embryos) in terms of embryo quality (Chi^2 p-value =0,0975) so we were able to compare the overall implantation of similar quality populations.
Despite euploid implantation being higher as described in most studies, no statistical differences (Chi^2 p-value = 0,4344) were found in terms of implantation rates between mosaic (57,0%) and euploid (67,6%) blastocysts during the same period. There are no differences between the mean age of both groups (39,7 vs 38,8 years, respectively).
The implantation rates for euploid blastocysts were 79,5% (n = 39), 62,7% (n = 51) and 33,3% (n = 6) in the A, B and C blastocyst quality groups, respectively, showing significative differences among the three groups.
The implantation rates of low-risk mosaic blastocysts were 100% (n = 3), 62,5% (n = 8) and 0,0% (n = 3) in the A, B and C blastocyst morphology groups, respectively, showing also still significant differences among the three groups despite the small population. (Chi^2 p-values according to implantation: Euploid =0,0434; Mosaic=0,0419)
We have also compared the three quality categories between both populations showing no significative differences (Chi^2 p-values according to quality: A = 0,4344; B = 0,9894; C = 0,2568), concluding that same quality embryos behave the same way despite being euploid or mosaic.
Limitations, reasons for caution
The study is limited by its retrospective nature and the low number of mosaic embryos transferred as they are the last option for transfer. Additionally, it is common to transfer more than one mosaic embryo to increase the chances of pregnancy, therefore losing implantation track.
Wider implications of the findings: Embryo quality has always been a strong biomarker predictable for implantation and this is also true for mosaic embryos as well. It is a simple concept, but we cannot compare implantation potential of euploid embryos with mosaic embryos without describing both populations in terms of quality.

Abstract
We studied the rapid decline in the number of breeding pairs (geometric growth rate λ = 0.86; 14 % annual decrease) of a semi–colonial ground–nesting bird of prey, the Montagu’s harrier (Circus pygargus), after twelve years of rapid population growth (λ = 1.15; 15 % rate of annual increase) in a protected coastal wetland in Eastern Spain. The study was conducted from 1992–2017, and the range of values in population size was: 2–37 breeding pairs. We contrasted 20 biologically–sound hypotheses (including local and regional factors) to explain the trend over time in the annual number of pairs. The most parsimonious model included a surrogate of wild boar (Sus scrofa) density in the region during the previous year and the annual number of Montagu’s harrier pairs breeding inland in the study province during the focal year. Syntopic western marsh harriers (C. aeruginosus) were not found to have any effect on the numbers of Montagu’s harriers either in our modelling or when we performed a quantitative and qualitative study both for years t and t–1. Our final ‘best’ models did not include spring rainfall, regional forest fires or local land use changes. The impact of wild boars on breeding success, together with conspecific attraction, could have resulted in the dispersal of coastal wetland birds to larger populations in dense inland shrub lands where levels of wild boar nest predation were more likely lower

Abstract
Background:Inflammatory bowel disease (IBD), which includes Crohn’s disease (CD), and Ulcerative colitis (UC) are related to Spondyloarthritis (SpA). Ocular manifestations (OM) are well-stablished in axial SpA but not in IBD. It has been classically reported that whereas uveitis with axial SpA is predominantly anterior, unilateral, acute, and non-recurrent; in IBD it is bilateral, posterior, insidious, and chronic (1).Objectives:In a large unselected series of IBD, our aim was to assess a) epidemiology and clinical features of uveitis associated to IBD, b) to compare patients who developed uveitis and those who did not, and c) its relationship with biological treatment used in IBD.Methods:Study of all consecutive patients from a single University Hospital during the last 40 years with: a) IBD (CD and UC), and b) uveitis according to Standarization Uveitis Nomenclature (SUN) Working Group. Demographic features, clinical findings, occurrence of other extraintestinal manifestations and treatment were recorded.Results:We studied 1449 (714 women/735 men) patients with IBD, mean age of 55.2±15.9 years.Uveitis was present in 23 (1.6 %) (38 eyes) of 1448 IBD patients. The most common pattern of uveitis was typically anterior (n=18; 78.3%), unilateral (n=19; 82.6%), acute (n=19; 82.6%), and non-recurrent (n=12; 52.2%).The comparative study between patients with and without uveitis showed a significant predominance of women (Table 1) in patients with uveitis, as well as erythema nodosum, hidradenitis suppurativa and joint involvement.Regarding IBD severity, in terms of surgical interventions, and conventional and biological immunosuppressive treatments, there were no significant differences.Conclusion:Although uveitis is more infrequent in IBD than in axial SpA, it is also anterior, unilateral, acute, and non-recurrent in contrast with published data from selected series. Patients with uveitis do not seem to represent more severe phenotype of IBD.References:[1]Lyons & Rosenbaum JT.

Abstract
The main objective of this work was to quantify the impact of handling of bulk materials on PM10 levels measured at the port-city border of Alicante (Spain), located on the western Mediterranean coast. To achieve that goal, 355 PM10 samples were collected at the perimeter of the harbor of Alicante from March 2017 to February 2018. A 181 sample subgroup was chemically characterized in order to perform a source apportionment study with the EPA PMF 5.0 model. Eight factors were identified, two of them directly related to the handling of bulk materials (Limestone + gypsum and Clinker), accounting jointly for 35% of the average PM10 concentration. A Road traffic factor was the second highest contributor to PM10 levels (17%) while the Shipping emissions factor accounted for only 6% of the average PM10 mass. Other factors such as Biomass burning+ secondary nitrate and Aged sea salt represented a joint contribution of 25% of the PM10 mass. Results indicate that emission abatement strategies should primarily focus on the reduction of fugitive emissions caused by the handling of bulk materials at the docks. Moreover, scenarios including reductions of more than 50% in bulk handling sources and 10% in other anthropogenic sources would help to reduce anthropogenic exceedances of the daily PM10 limit (50 μg·m-3) and to approach to WHO daily PM10 standard (20 μg m-3).

Abstract
Inflammatory bowel diseases (IBD) belong to the group of immune-mediated diseases (IMIDs). The effect of associated IMIDs in the prognosis in IBD is nowadays unknown. To describe IMIDs associated to IBD patients and evaluate differences linked to the presence or absence of IMIDs. A unicentric retrospective descriptive study was designed. A cohort of 1,448 patients were categorized according to the presence of IMIDs. Clinical characteristics were obtained from IBD database. Univariate and multivariate analysis were performed. 385 patients were diagnosed with associated IMIDs while 1,063 had no associated IMIDs. A prevalence of 26.6% IMIDs associated to IBD was observed. Asthma, skin psoriasis and rheumatoid diseases were most commonly found. Factors associated to the presence of IMIDs were women (OR 1.48; 95 CI 1.17–1.87) and Crohn’s disease (OR 1.35; 95 CI 1.07–1.70). Patients with associated IMIDs required more immunomodulator (OR 1.61; 95 CI 1.27–2.43) and biological treatment (OR 1.81; 95 CI 1.47–2.43). More surgical risk was observed in multivariate analysis in those patients diagnosed with IMIDs prior to the onset of IBD (OR 3.71; 95% CI 2.1–6.56). We considered the presence of IMIDs a poor prognostic factor and suggest a closer monitoring of these patients.

Ocular manifestations (OM) are well-stablished in SpA but not in IBD. It has been classically reported that whereas uveitis with SpA is predominantly anterior, unilateral, sudden, and limited; in IBD it is bilateral, posterior, insidious, and chronic(Lyons & Rosenbaum JT. Arch Ophthalmol 1997; 115:61-4).Objectives:In a large unselected series of IBD, we study the OM and assess;a) epidemiological, clinical features,b) the relationship with extraintestinal manifestations.Methods:Study of all consecutive patients from a single University Hospital during the last 40 years with: a) IBD (CD and UC), andb) OM: uveitis and scleral pathology diagnosed by clinical features and slit-lamp.Results:OM were present in 42 (2.9%) (25 women/17 men) (84 eyes) of 1442 IBD patients; OM included the uveitis group (UG) (n=23; 1.6%) and the scleral pathology group (SG) (n=19, 1.32%) (TABLE).The most common pattern in SG was episcleritis (n=16; 84.21%) and scleritis (n=3). In UG, uveitis was typically anterior (n=18; 78.3%), unilateral (n=19; 82.6%), sudden (n=19; 82.6%), and limited (n=12; 52.2%).The comparative study between SG vs UG showed in UG a significant predominance of women and UC. Also, a non-significative higher frequency in Pyoderma gangrenosum, erythema nodosum and joint involvement was observed in UG.After a mean follow-up of 15.2±9.97 years, extraintestinal manifestations were observed in 100% of patients, being articular forms (n=16; 38.10%) the most common type. In addition, joint/axial flare is more related to the presence of uveitis (p=0.038).Conclusion:Both uveitis and episcleritis are equally frequent OM in IBD. Although uveitis is more infrequent in IBD than in SpA, it is also anterior, unilateral, sudden and limited in contrast with published data from selected series.References:[1]Lyons & Rosenbaum JT.

Abstract
Organic carbon (OC) and elemental carbon (EC) concentrations were measured in PM1 and PM10 daily samples collected at an urban station in Elche (southeastern Spain) from February 2015 to February 2018. The effect of seasonal weather conditions, traffic, and specific pollution events (Saharan dust outbreaks and local pollution episodes) on the variability of carbonaceous aerosol levels was studied in this work. The joint contribution of carbonaceous species to PM1 and PM10 mass concentrations was, respectively, 48% and 26%. Both OC and EC concentrations were higher in winter than in summer because of the poor dispersion conditions and lower temperatures leading to the condensation of semivolatile species. Secondary organic carbon (SOC), estimated using the EC tracer method, also exhibited higher concentrations during winter, indicating that the prevailing meteorological conditions during the cold season are more favorable for the formation of secondary organic aerosols. Our results suggest different formation pathways of secondary organic components during summer and winter. At the sampling site, EC was primarily derived from traffic emissions, independently of the season and the type of event, with a modest contribution from biomass burning (<20%). The estimated contribution from this source to OC levels was similar. Local pollution episodes lead to a significant increase in the concentrations of carbonaceous species, in particular of SOC, influencing its temporal variation. On average, African dust outbreaks showed a moderate impact on the levels of carbonaceous aerosols; however, the effect was significantly stronger during winter Saharan events.

Abstract
Abstract
Background and aims
Chronic infection with hepatitis B virus (HBV) can progress to liver cirrhosis and lead to complications such as decompensated liver disease, hepatocellular carcinoma and liver-related death. Antiviral agents against HBV are very effective in suppressing viremia and greatly reduce the risk of complications if treatment is initiated before the onset of advanced liver disease. The aim of this study is to assess the prevalence of late presentation in leading hospitals across Spain.
Methods
Retrospective cohort study of patients seeking first time care with a liver specialist at six tertiary Spanish hospitals, with 2018 data. Late presentation (LP) included advanced liver disease (ALD) defined by significant fibrosis (≥ F3 assessed by either APRI score > 1.5, FIB-4 > 3.2, transient elastography (FibroScan) > 9.5 kPa or biopsy ≥ METAVIR stage F3) with no previous antiviral treatment and late-stage liver disease (LSLD) was defined by the presence of decompensated cirrhosis and/or hepatocellular carcinoma. Prevalence of ALD and LSLD at first consultation, demographics, and associated risk factors were analysed.
Results
203 patients chronically infected with HBV were included. Advanced liver disease was detected in 14.8% and late stage liver disease was observed in 6.1% of cases. 57.1% of the cases were male. The majority of those with HBV were non-Spanish (53.7%). The median age was 47 and the median of years from diagnosis to specialist care was 1 (IQR 7). 58.6% of patients were referred from primary care and 3.7% cases had hepatocellular carcinoma upon presentation for care.
Conclusions
Late presentation with HBV is common in Spain, particularly for the foreign-born population, despite full access to antiviral therapy for HBV in the country. In order to rectify this health systems failure, improve outcomes and reach the viral hepatitis elimination goal adopted by WHO in 2016, strategies to reduce late presentation to care are essential.
Key messages
Early diagnosis of HBV is needed in order to rectify the health systems failure of late presentation to care. Interventions targeting foreign-born populations should be implemented to reduce late presentation to HBV care and treatment.

Abstract
Abstract
Background/Introduction
Microvesicles (MV) are small phospholipid-rich vesicles released into blood by cells that are either damaged, activated or apoptotic. MV participate in diverse functions and also can serve as biomarkers of ongoing cardiovascular cell instability and disease (CVD). Diet is one of cornerstones for CVD prevention, and the effects of diet on MV shedding are poorly characterized.
Purpose
We aimed at investigating the long term effects of a mediterranean diet compared to a low fat diet (LFD) in MV shedding by cells of the vascular compartment in asymptomatic but high cardiovascular risk patients treated as per guidelines.
Methods
A total of 155 patients with diabetes or >3 cardiovascular risk factors but free of cardiovascular event were included in the study, consisting in a 3-arm randomized clinical trial. The interventions were as follows: a mediterranean diet supplemented with extra-virgin olive oil -EVOO- (n=53); a mediterranean diet supplemented with mixed nuts -NUTS- (n=49); and a control diet -LFD- (n=53) for one year. Subjects were matched by age, sex, diabetes and dyslipidaemia. At baseline and after one year follow-up, the number of MV and their phenotypic characteristics were assessed by flow cytometry. Phosphatidylserine exposure by annexin V (AV) binding was assessed and different monoclonal antibodies against characteristic cell epitopes were used to identify parental cell origin.
Results
The mean patient age was 66 years (50% males). Patients were hypertensive (>75%), diabetics (>50%) and dyslipidemics (>30%). No significant changes were observed after one year follow-up in body weight, body mass index, blood pressure, glucose, triglycerides, total, LDL and HDL cholesterol, medication or physical activity within or among groups of intervention.
Total MV (AV+/−) were present in higher concentration than AV+ MV for all analyzed phenotypes and cell origins (P<0.0001, all). After one year follow-up, in the EVOO group there was a significant decrease in the concentration of monocyte-derived (CD14+/AV+, CD14+/CD11a+/AV+) and smooth muscle cell-derived (SMA-α+/AV+) circulating MV. In the NUTS group there was a significant decrease in platelet-derived (PAC-1+/AV+, CD62P+/AV+, and CD61+/AV+) MV, and activated cells-derived (CD142+/AV+, CD11a+/AV+ and CD63+/AV+) MV concentrations. On the other hand, one year of LFD decreased platelet PAC-1+/CD62P+/AV+ and CD61+/AV+ MV release. Interestingly, after one year follow-up PAC-1+/AV+ and CD14+/CD11a+/AV+ MV were significantly different between both mediterranean diets compared to the LFD.
Conclusions
MV are liquid biopsy biomarkers of vascular- and blood-cell activation and injury, that appear sensitive to modification by diet. Therefore, our results indicate that following a mediterranean diet rich in nuts and EVOO clearly prevent cell activation towards a pro-atherosclerotic phenotype and therefore can delay the development of CV complications.

Abstract
Abstract
Background
Atherosclerosis, the leading cause of cardiovascular diseases, is driven by high blood cholesterol levels and chronic inflammation. The disruption of the hepatic interaction between Proprotein Convertase Subtilisin/Kexin 9 (PCSK9) and Low-Density Lipoprotein Receptor (LDLR) downregulates blood cholesterol levels and reduces cardiovascular events. Recent data suggest that other members of the LDLR superfamily may be targets of PCSK9.
Purpose
The aim of this work is to determine if LDLR-related protein 5 (LRP5) is a PCSK9 target, and to study the role of PCSK9 and LRP5 in foam cell formation and hence, in the mechanism of lipid accumulation and atherosclerotic plaque formation.
Methods
Intracellular protein and lipid localization, cholesteryl esters (CE) accumulation; quantification of structural and inflammatory proteins expression and immunoprecipitation analyses were performed in primary cultures of human inflammatory cells (monocytes and macrophages) silenced for LRP5 or PCSK9 and challenged with modified LDLs.
Results
We first show that LRP5 is needed for macrophage lipid uptake since LRP5-silenced macrophages have less intracellular CE accumulation. In LDL treated macrophages internalization of LRP5-bound LDL starts after 30 minutes of incubation and lasts up to 24hours. The SREBP-2 promoter is not involved in LRP5 regulation but it does regulate macrophage PCSK9 expression. Immunoprecipitation experiments show that LRP5 forms a complex with PCSK9 in lipid-loaded macrophages. Finally we studied the role of PCSK9 and LRP5 in the inflammatory response by TLR4/NFkB signaling pathway. We show decreased TLR4 protein expression levels and decreased nuclear translocation of NFκB in PCSK9 silenced-inflammatory cells after lipid loading indicating a downregulation of the proinflammatory pathway TLR4/NFκB. Increased gene expression is observed in TNF-α and IL1β after lipid-loading that is abolished in PCSK9-silenced macrophages. Furthermore release of the proinflammatory cytokines TNF-α and IL1β is decreased in PCSK9-silenced macrophages. LRP5 protein expression is increased in lipid-loaded macrophages independent of the presence or absence of PCSK9.
Conclusions
These results demonstrate that, in human macrophages, LRP5 is internalized with lipids. Furthermore, PCSK9 and LRP5 can form a complex in the cytoplasm of lipid-loaded macrophages opening the possibility that PCSK9 induces lysosomal LRP5 degradation in a similar manner than it does with LDLR. Finally we also show that PCSK9 gene interference decreases inflammation and supports a role for PCSK9 as an inflammatory mediator in atherosclerosis.

Abstract
BACKGROUND Some chronic inflammatory skin diseases, such as psoriasis, have been associated with an increased prevalence of non-alcoholic fatty liver disease (NAFLD). Nevertheless, this prevalence in hidradenitis suppurativa (HS) has not been assessed to date. OBJECTIVES To determine the prevalence of NAFLD in patients with HS and the risk factors associated with this disorder. METHODS This case-control study enrolled 70 HS patients and 150 age- and gender-matched controls who were evaluated by hepatic ultrasonography (US) and transient elastography (TE) after excluding other secondary causes of chronic liver disease. The diagnosis of NAFLD was established if US and/or TE were altered. RESULTS The prevalence of NAFLD was significantly increased in patients with HS compared to controls (72.9% vs. 24.7%: P < 0.001). In the multivariable regression model adjusted for age, sex and classic metabolic risk factors for NAFLD, HS was significantly and independently associated with the presence of NAFLD [OR 7.75 confidence interval (CI) 2.54-23.64; P < 0.001]. CONCLUSIONS Our results show a high prevalence of NAFLD in HS patients independent of classic metabolic risk factors. Therefore, we suggest HS patients to be evaluated for NAFLD and managed accordingly.

Abstract
BACKGROUND Cardiogenic shock (CS) is the leading cause of death in patients admitted for acute myocardial infarction (MI). Despite the recent advances in reperfusion and medical treatment mortality remains unacceptably high. Whether cells of the blood compartment in CS-patients are activated and release microparticles (cMPs) that may be both messengers and biomarkers of cell damage is not known. We aimed to investigate the cMP subtypes and parental activated cells of ST-elevation MI (STEMI)-patients complicated by CS and that of non-CS STEMI-patients (non-CS) in order to identify a cMP signature that could aid CS patient's risk stratification. METHODS Clinically-characterized STEMI-patients with and without CS (36/group) were included. Treatment was delivered according to guidelines and included primary percutaneous coronary intervention. cMPs were characterized by triple-labeling flow cytometry using Annexin V and cell surface-specific monoclonal antibodies. RESULTS Increased levels of leukocyte-derived (neutrophil and granulocyte origin) and platelet-derived cMPs were detected in CS compared to non-CS patients. A signature of cMPs derived from platelets, leukocytes, and endothelium discriminated CS-patients (AUC of 0.743±0.059 [95% CI: 0.628-0.859], P<0.0001) and predicted mortality in CS (AUC of 0.869±0.06 [95% CI: 0.750-0.988], P<0.0001). In CS-patients, a higher number of platelet- and monocyte-cMPs and of tissue factor-rich cMPs associated to worse myocardial blush grade and thrombolysis in myocardial infarction flow. CONCLUSIONS cMPs derived from proinflammatory and prothrombotic cells were found to be elevated in CS-patients. In treated as per guidelines CS patients, granulocytes and neutrophils remained activated and actively shed cMPs. These cMPs were biomarkers of adverse prognosis in CS. TRANSLATIONAL ASPECT Increased levels of leukocyte and platelet-derived circulating microparticles (cMPs) are found in cardiogenic shock (CS) patients as compared to non-CS patients. In CS-patients, a higher number of platelet- and monocyte-cMPs and a higher number of tissue factor-rich cMPs were associated to worse myocardial reperfusion. A specific prothrombotic and proinflammatory cMPs signature in cardiogenic shock (CS) patients is a potential discriminator and survival prognostic biomarker for CS, which could aid management and improve clinical outcomes.

Abstract
PM1 and PM10 samples collected in the urban center of Elche during two years were analyzed by Energy Dispersive X-Ray Fluorescence in order to determine the concentrations of the following metals: K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Sr and Ba. The influence of traffic and Saharan dust intrusions on PM levels and metal content was studied in this work. The results indicate that the coarse fraction was affected more by variations in traffic intensity than the submicron fraction. The concentrations of Ca, commonly used as a tracer of road dust, showed the highest decreases during the weekends due to the reduction in traffic-induced resuspension. In contrast, Saharan events had a greater impact on the levels of other metals such as Ti and Fe, significantly affecting their seasonal variability. High concentrations of V and Ni compared with the values found at larger urban areas were observed. This could be attributed to a significant contribution from soils, Saharan dust and even ship emissions. Enrichment factors calculated using Ti as a reference element indicate that Zn and Cu are predominantly emitted by anthropogenic activities. In fact, Saharan dust intrusions had a minor influence on the average concentrations of these metals. Non-carcinogenic health hazards associated with exposure to airborne metals were lower than the safety threshold (hazard quotient < 1). Carcinogenic risks for Cr (VI) and Ni were between 10-6 and 10-4 and, therefore, within the range considered acceptable by the US EPA.

Abstract
Summary
Objective: To analyze the scientific and engineering components of Medical Informatics. A clear characterization of these components should be undertaken to categorize different areas of Medical Informatics and create a research agenda for the future. Methods: We have adapted a classical ACM and IEEE report on computing to analyze Medical Informatics from three different viewpoints: Theory, Abstraction, and Design.
Results: We suggest that Medical Informatics can be considered from these three perspectives: (1) Theory, from which medical informaticians formally characterize the properties of the objects of study, creating new theories or using and adapting existing theories (e.g., from mathematics), (2) Abstraction, from which medical informaticians deal with all aspects of medical information and create new abstractions, methods, and technology-independent models, which can be experimentally verified, and (3) Design, from which medical informaticians develop systems or act as information brokers or advisors between medical and technology professionals, to improve the quality of computer applications in medicine.
Conclusion: Based on this framework, we suggest that Medical Informatics has an independent scientific character, different from other applied informatics areas. Finally, we analyze these three perspectives using data mining in medicine.

Abstract
Summary
Objectives:
To develop a new perspective for biomedical information systems, regarding the introduction of ideas, methods and tools related to the new scenario of genomic medicine.
Methods:
Technological aspects related to the analysis and integration of heterogeneous clinical and genomic data include mapping clinical and genetic concepts, potential future standards or the development of integrated biomedical ontologies. In this clinicomics scenario, we describe the use of Web services technologies to improve access to and integrate different information sources. We give a concrete example of the use of Web services technologies: the Onto Fusion project.
Results:
Web services provide new biomedical informatics (BMI) approaches related to genomic medicine. Customized workflowswill aid research tasks by linking heterogeneous Web services. Two significant examples of these European Commission-funded efforts are the INFOBIOMED Network of Excellence and the Advancing Clinico-Genomic Trials on Cancer (ACGT) integrated project.
Conclusions:
Supplying medical researchers and practitioners with omicsdata and biologists with clinical datasets can help to develop genomic medicine. BMI is contributing by providing the informatics methods and technological infrastructure needed for these collaborative efforts.

Abstract
Two experiments were performed to study the effects of the citrus flavonoid extract Bioflavex (BF; Interquim SA, FerrerHealthTech, Sant Cugat, Barcelona, Spain) or its components on the rumen fermentation of a high-concentrate diet. In an in vivo experiment, eight Friesian steers (398 ± 12.2 kg bodyweight) fitted with a rumen cannula were given a basal concentrate (CTR) or a CTR supplemented with BF (450 mg/kg dry matter, DM) in a 2 × 4 crossover design. No differences were observed in performance parameters of BF and CTR steers. Diet BF increased pH values and the molar proportion of propionate and reduced lactate concentration as a result of an increase in the relative abundance of lactate-consuming microorganism Selenomomas ruminantium (P < 0.01) and Megaesphaera elsdenii (P = 0.06). In an in vitro experiment, the effect of BF and its pure flavonoid components added to the incubation medium was studied separately. Bioflavex and its main components naringine, neohesperidine (NH) and poncirine (PC) were added to the incubation medium at 500 µg/g DM, with the unsupplemented substrate also included as a control (CTR). After 12 h of incubation, flavonoid mixture and NH and PC reduced (P < 0.01) the volume of gas produced and the molar proportion of acetate (P < 0.01), and increased that of propionate (P < 0.01). PC reduced the relative quantification of Streptococcus bovis, whereas NH and BF increased the relative quantification of M. elsdenii in relation to CTR (P < 0.01). Bioflavex supplementation in steers in feedlot was effective in preventing a collapse in pH and it enhanced rumen fermentation efficiency through modifying the activity of lactate-consuming bacteria and a greater molar proportion of propionate and a reduction of that of acetate, suggesting its positive role in modulating the activity of rumen microbiota.

Essentials Monocytes (Mo) transdifferentiate into endothelial cell-like (ECL) cells. Mo induce tissue factor (TF) expression and secretion in microvascular endothelial cells (mECs). TF interacts with Mo in a paracrine fashion, inducing their transdifferentiation into ECL cells. TF generates a positive feedback crosstalk between Mo and mECs that promotes angiogenesis. SUMMARY Background Monocytes (Mo) increase neovascularization by releasing proangiogenic mediators and/or transdifferentiating into endothelial cell-like (ECL) cells. Recently, we have reported that Mo-microvascular endothelial cells (mECs) crosstalk induces mEC-tissue factor (TF) expression and promotes angiogenesis. However, the effect of TF on Mo remains unknown. Objective Here, we analyzed whether TF might exert angiogenic effects by inducing transdifferentiation of Mo. Methods Full-length TF (flTF) and alternatively spliced TF (asTF) were overexpressed in mECs, and their supernatants were added to Mo cultures. CD16 positivity and expression of vascular endothelial cell (VEC) markers in Mo were analyzed by fluorescence activated cell sorting. The capacity to form tube-like structures were visualized in three-dimensional cultures. Results In mECs flTF and asTF expression and release were increased in cultures with Mo-conditioned media. TF variants induced expansion of a CD16+ Mo subset and Mo transdifferentiation into ECL-cells expressing VEC markers that can form new microvessels. CD16+ Mo exposed to TF showed an increased expression of VE-cadherin, von Willebrand factor (VWF) and eNOS. Mo cultured with supernatants obtained from TF-silenced mECs did not transdifferentiate to ECL-cells or expressed VEC markers. Blocking β1-integrin in Mo significantly blocked the effects of the TF variants. Conclusions Mo induce mECs to express and release TF, which drives CD16- Mo to transform into CD16+ Mo and to transdifferentiate into ECL-cells that can form new microvessels. Our results reveal a TF-mediated positive feedback between mECs and Mo that stimulates Mo differentiation and induces angiogenesis.

Abstract
Over the last 5 years, therapies for hepatitis C virus (HCV) infection have improved significantly, achieving sustained virologic response (SVR) rates of up to 100% in clinical trials in patients with HCV genotype 1. We investigated the effectiveness and safety of ombitasvir/paritaprevir/ritonavir±dasabuvir in an early access programme. This was a retrospective, multicentre, national study that included 291 treatment-naïve and treatment-experienced patients with genotype 1 or 4 HCV infection. Most patients (65.3%) were male, and the mean age was 57.5 years. The mean baseline viral load was 6.1 log, 69.8% had HCV 1b genotype, 72.9% had cirrhosis and 34.7% were treatment-naïve. SVR at 12 weeks posttreatment was 96.2%. Four patients had virological failure (1.4%), one leading to discontinuation. There were no statistical differences in virological response according to genotype or liver fibrosis. Thirty patients experienced serious adverse events (SAEs) (10.3%), leading to discontinuation in six cases. Hepatic decompensation was observed in five patients. Four patients died during treatment or follow-up, three of them directly related to liver failure. Multivariate analyses showed a decreased probability of achieving SVR associated with baseline albumin, bilirubin and Child-Pugh score B, and a greater probability of developing SAEs related to age and albumin. This combined therapy was highly effective in clinical practice with an acceptable safety profile and low rates of treatment discontinuation.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is a leading cause of liver cirrhosis and subsequent hepatocellular carcinoma. HCV genotype 4 is found widely in the Middle East, Egypt and Africa, and has also spread into Europe. There are limited data available regarding the use of direct-acting antiviral agents in HCV genotype 4-infected patients with cirrhosis. AIM To evaluate in the phase III, open-label, single-arm PLUTO study the efficacy and safety of 12 weeks of simeprevir (HCV NS3/4A protease inhibitor) plus sofosbuvir (HCV nucleotide-analogue NS5B polymerase inhibitor) in treatment-naïve and (peg)interferon ± ribavirin-experienced HCV genotype 4-infected patients, with or without compensated cirrhosis. METHODS Adult patients with chronic HCV genotype 4 infection received simeprevir 150 mg once-daily and sofosbuvir 400 mg once-daily for 12 weeks. The primary efficacy endpoint was sustained virologic response 12 weeks after the end of treatment (SVR12). Safety was also assessed. RESULTS Forty patients received treatment; the majority were male (73%) and treatment-experienced (68%). Overall, 7/40 (18%) patients had compensated cirrhosis. All patients achieved SVR12 [100% (Clopper-Pearson 95% confidence interval: 91-100%)]. Adverse events, all Grade 1 or 2, were reported in 20/40 (50%) patients. No serious adverse events were reported and no patients discontinued study treatment. Grade 3 treatment-emergent laboratory abnormalities were noted in 2/40 (5%) patients. CONCLUSIONS Treatment with simeprevir plus sofosbuvir for 12 weeks resulted in SVR12 rates of 100% in treatment-naïve and -experienced patients with HCV genotype 4 infection with or without compensated cirrhosis, and was well tolerated.

Abstract
From May to September 2012, ozone reductions associated with 15 Saharan dust outbreaks which occurred between May to September 2012 have been evaluated. The campaign was performed at a mountain station located near the eastern coast of the Iberian Peninsula. The study has two main goals: firstly, to analyze the decreasing gradient of ozone concentration during the course of the Saharan episodes. These gradients vary from 0.2 to 0.6 ppb h(-1) with an average value of 0.39 ppb h(-1). The negative correlation between ozone and coarse particles occurs almost simultaneously. Moreover, although the concentration of coarse particles remained high throughout the episode, the time series shows the saturation of the ozone loss. The highest ozone depletion has been obtained during the last hours of the day, from 18:00 to 23:00 UTC. Outbreaks registered during this campaign have been more intense in this time slot. The second objective is to establish from which coarse particle concentration a significant ozone depletion can be observed and to quantify this reduction. In this regard, it has been confirmed that when the hourly particle concentration recorded during the Saharan dust outbreaks is above the hourly particle median values (N > N-median), the ozone concentration reduction obtained is statistically significant. An average ozone reduction of 5.5 % during Saharan events has been recorded. In certain cases, this percentage can reach values of higher than 15 %.

Abstract
AIM The enumeration of intraepithelial lymphocytes subsets (total, γδ, and CD3(-) IELs) by flow cytometry (FCM), named as IEL lymphogram, constitutes a useful tool for celiac disease (CD) diagnosis. The aim of this study was to quantify IELs by FCM and their diagnostic value to differentiate active, silent and potential CD. METHODS Prospective study of 60 active and 20 silent CD patients, and 161 controls in which duodenal biopsy and IEL quantification by FCM was performed. RESULTS Active and silent CD patients had significant higher levels of both total and γδ IELs than absent CD patients (P < 0.0001 and P < 0.0001, P = 0.012 and P < 0.011; respectively). Active and silent CD patients had significant lower levels of CD3(-) IELs than absent CD patients (P < 0.047 and P < 0.009, respectively). Moreover, they were lower in silent than in active CD patients (P = 0.002). Changes of IELs subsets were more marked in children than adults active CD. The optimal IEL lymphogram cut off values for active CD diagnosis were: ≥10, ≥15 and ≤9 %, and with better performance characteristics for silent CD: ≥ 11, ≥10 and ≤5 %. CONCLUSION The evaluation of IELs subsets by FCM is useful to confirm diagnosis of active and silent CD.

Abstract
Autoantibodies specific for double stranded DNA (anti-dsDNA Abs) are a serological biomarker of systemic lupus erythematosus (SLE) and constitute useful tools for monitoring many SLE patients. A new automated immunofluorescence and quantitative assay (EliA dsDNA) has recently become available. Its performance has been demonstrated to be equivalent to the Farr and Crithidia luciliae fluorescence (CLIFT) tests. The aim of the present work was to assess the utility of this new assay to monitor clinical activity in a large cohort of SLE patients. To this end, 1020 sera from 181 SLE patients were evaluated by the two methods. Results showed a higher frequency of positive results of anti-dsDNA Abs during lupus flares measured by EliA dsDNA than by CLIFT. Likewise, titers of those Abs were significantly increased in active SLE in comparison with inactive SLE when measured by EliA dsDNA but not by CLIFT. Serum titers of anti-dsDNA Abs by both assays showed a significant negative association with concentrations of C3 and C4. In summary, this retrospective study on a large cohort of patients demonstrated that EliA dsDNA was at least as useful as CLIFT as monitoring tool in the follow-up of SLE patients, but with the advantages of being automated, quick and quantitative.

Abstract
BACKGROUND & AIMS Elafibranor is an agonist of the peroxisome proliferator-activated receptor-α and peroxisome proliferator-activated receptor-δ. Elafibranor improves insulin sensitivity, glucose homeostasis, and lipid metabolism and reduces inflammation. We assessed the safety and efficacy of elafibranor in an international, randomized, double-blind placebo-controlled trial of patients with nonalcoholic steatohepatitis (NASH). METHODS Patients with NASH without cirrhosis were randomly assigned to groups given elafibranor 80 mg (n = 93), elafibranor 120 mg (n = 91), or placebo (n = 92) each day for 52 weeks at sites in Europe and the United States. Clinical and laboratory evaluations were performed every 2 months during this 1-year period. Liver biopsies were then collected and patients were assessed 3 months later. The primary outcome was resolution of NASH without fibrosis worsening, using protocol-defined and modified definitions. Data from the groups given the different doses of elafibranor were compared with those from the placebo group using step-down logistic regression, adjusting for baseline nonalcoholic fatty liver disease activity score. RESULTS In intention-to-treat analysis, there was no significant difference between the elafibranor and placebo groups in the protocol-defined primary outcome. However, NASH resolved without fibrosis worsening in a higher proportion of patients in the 120-mg elafibranor group vs the placebo group (19% vs 12%; odds ratio = 2.31; 95% confidence interval: 1.02-5.24; P = .045), based on a post-hoc analysis for the modified definition. In post-hoc analyses of patients with nonalcoholic fatty liver disease activity score ≥4 (n = 234), elafibranor 120 mg resolved NASH in larger proportions of patients than placebo based on the protocol definition (20% vs 11%; odds ratio = 3.16; 95% confidence interval: 1.22-8.13; P = .018) and the modified definitions (19% vs 9%; odds ratio = 3.52; 95% confidence interval: 1.32-9.40; P = .013). Patients with NASH resolution after receiving elafibranor 120 mg had reduced liver fibrosis stages compared with those without NASH resolution (mean reduction of 0.65 ± 0.61 in responders for the primary outcome vs an increase of 0.10 ± 0.98 in nonresponders; P < .001). Liver enzymes, lipids, glucose profiles, and markers of systemic inflammation were significantly reduced in the elafibranor 120-mg group vs the placebo group. Elafibranor was well tolerated and did not cause weight gain or cardiac events, but did produce a mild, reversible increase in serum creatinine (effect size vs placebo: increase of 4.31 ± 1.19 μmol/L; P < .001). CONCLUSIONS A post-hoc analysis of data from trial of patients with NASH showed that elafibranor (120 mg/d for 1 year) resolved NASH without fibrosis worsening, based on a modified definition, in the intention-to-treat analysis and in patients with moderate or severe NASH. However, the predefined end point was not met in the intention to treat population. Elafibranor was well tolerated and improved patients' cardiometabolic risk profile.

Abstract
INTRODUCTION The achievement of a state of tolerance and minimization of the immunosuppressive load form part of the "Holy Grail" in solid organ transplantation. Galectin-1 recently has been described to be involved in the maintenance of a tolerant environment, but there is no evidence of its role in human liver transplantation. The aim of our study was to measure the serum levels of galectin-1 in stable liver transplant recipients. METHODS Serum levels of galectin-1 were determined in 30 stable liver transplant recipients who had been free of rejection episodes for at least 8 years. Fifteen patients with an acute rejection episode and 34 healthy subjects were used as the control group. RESULTS The concentrations of galectin-1 were significantly higher in stable liver transplant recipients compared with healthy subjects and with the acute rejection group. CONCLUSIONS These preliminary results indicate that galectin-1 is upregulated in stable liver transplant recipients. Thus, our results extend the recent findings that galectin-1 may play an immune-suppressive role in liver transplantation. It remains to be established whether it might help to induce tolerance in liver transplantation.

Abstract
Seasonal changes in the levels of PM1 and its main components (organic carbon (OC), elemental carbon (EC), SO4 (2-), NO3 (-) and NH4 (+)) were studied in an urban street canyon in southeastern Spain. Although PM1 levels did not show an evident seasonal cycle, strong variations in the concentrations of its major components were observed. Ammonium sulfate, the main secondary inorganic compound, was found to be of regional origin. Its formation was favored during summer due to increased photochemical activity. In contrast, the concentrations of particulate ammonium nitrate, which is thermally unstable, were highest in winter. Although traffic emissions are the dominant source of EC in the city, variations in traffic intensity could not explain the seasonal cycle of this component. The higher EC concentrations during the cold months were attributed to the lower dispersion conditions and the increase in EC emissions. Special attention has been given to variations in organic carbon levels since it accounted for about one third of the total PM1 mass. The concentrations of both total OC and secondary OC (SOC) were maxima in winter. The observed seasonal variation in SOC levels is similar to that found in other southern European cities where the frequency of sunny days in winter is high enough to promote photochemical processes.

Abstract
In this study, we assessed the association between single-nucleotide polymorphisms (SNPs) in seven candidate genes involved in orchestrating the immune response against cytomegalovirus (CMV) and the 12-month incidence of CMV infection in 315 CMV-seropositive kidney transplant (KT) recipients. Patients were managed either by antiviral prophylaxis or preemptive therapy. CMV infection occurred in 140 patients (44.4%), including 13 episodes of disease. After adjusting for various clinical covariates, patients harboring T-allele genotypes of interleukin-28B (IL28B) (rs12979860) SNP had lower incidence of CMV infection (adjusted hazard ratio [aHR]: 0.66; 95% confidence interval [CI]: 0.46-0.96; p-value = 0.029). In the analysis restricted to patients not receiving prophylaxis, carriers of the TT genotype of toll-like receptor 9 (TLR9) (rs5743836) SNP had lower incidence of infection (aHR: 0.61; 95% CI: 0.38-0.96; p-value = 0.035), whereas the GG genotype of dendritic cell-specific ICAM 3-grabbing nonintegrin (DC-SIGN) (rs735240) SNP exerted the opposite effect (aHR: 1.86; 95% CI: 1.18-2.94; p-value = 0.008). An independent association was found between the number of unfavorable SNP genotypes carried by the patient and the incidence of CMV infection. In conclusion, specific SNPs in IL28B, TLR9 and DC-SIGN genes may play a role in modulating the susceptibility to CMV infection in CMV-seropositive KT recipients.
