Abstract
The present study sought to describe the use of generic drugs and single-tablet regimen (STR) de-simplification for the treatment of human immunodeficiency virus (HIV) infection among 41 hospitals from the cohort of the Spanish HIV/AIDS Research Network (CoRIS). In June 2018, we collected information on when generic antiretroviral drugs (ARVs) were introduced in the different hospitals, how the decisions to use them were made, and how the information was provided to the patients. Most of the nine available generic ARVs in Spain by June 2018 had been introduced in at least 85% of the participating hospitals, except for zidovudine (AZT)/lamivudine (3TC) and AZT. The time difference between the effective marketing date of each generic ARV and its first dispensing date in the hospitals was much shorter for the more recently approved generic ARV since the year 2017. However, only up to 20% of the hospitals de-simplified efavirenz (EFV)/tenofovir disoproxil (TDF)/emtricitabine (FTC), dolutegravir (DTG)/abacavir (ABC)/3TC, and rilpivirine (RPV)/TDF/FTC (to generic EFV+TDF/FTC, DTG+generic ABC/3TC, and RPV+generic TDF/FTC, respectively), whereas the generic STR EFV/TDF/FTC was introduced in 87.8% of the centers. The median times between the date of effective marketing of generic TDF/FTC and the date of de-simplification of EFV/TDF/FTC and RPV/TDF/FTC were 723 [interquartile range (IQR): 369-1,119] and 234 (IQR: 142-264) days, respectively; this time was 155 (IQR: 28-287) days for de-simplification of DTG/ABC/3TC. In conclusion, despite the widespread use of generic ARVs, STRs de-simplification was only undertaken in <20% of the hospitals. There was wide variability in the timing of the introduction of each generic ARV after they were available in the market.

Abstract
Objectives We assessed the prevalence of anti‐hepatitis C virus (HCV) antibodies and active HCV infection (HCV‐RNA‐positive) in people living with HIV (PLWH) in Spain in 2019 and compared the results with those of four similar studies performed during 2015–2018. Methods The study was performed in 41 centres. Sample size was estimated for an accuracy of 1%. Patients were selected by random sampling with proportional allocation. Results The reference population comprised 41 973 PLWH, and the sample size was 1325. HCV serostatus was known in 1316 PLWH (99.3%), of whom 376 (28.6%) were HCV antibody (Ab)‐positive (78.7% were prior injection drug users); 29 were HCV‐RNA‐positive (2.2%). Of the 29 HCV‐RNA‐positive PLWH, infection was chronic in 24, it was acute/recent in one, and it was of unknown duration in four. Cirrhosis was present in 71 (5.4%) PLWH overall, three (10.3%) HCV‐RNA‐positive patients and 68 (23.4%) of those who cleared HCV after anti‐HCV therapy (p = 0.04). The prevalence of anti‐HCV antibodies decreased steadily from 37.7% in 2015 to 28.6% in 2019 (p < 0.001); the prevalence of active HCV infection decreased from 22.1% in 2015 to 2.2% in 2019 (p < 0.001). Uptake of anti‐HCV treatment increased from 53.9% in 2015 to 95.0% in 2019 (p < 0.001). Conclusions In Spain, the prevalence of active HCV infection among PLWH at the end of 2019 was 2.2%, i.e. 90.0% lower than in 2015. Increased exposure to DAAs was probably the main reason for this sharp reduction. Despite the high coverage of treatment with direct‐acting antiviral agents, HCV‐related cirrhosis remains significant in this population.

Abstract
BACKGROUND Although the association between HIV infection and airway obstruction is well known, its etiopathogenesis is not clear. OBJECTIVES Our aim was to analyze the association between biomarkers of systemic inflammation and bacterial translocation and pulmonary function tests in HIV-infected patients and compare the results between smokers and non-smokers. METHOD It was a cross-sectional, observational study. The inclusion criterion of the study was people living with HIV with undetectable plasma viral load. The exclusion criterion was other comorbidities associated with systemic inflammation. Outcome variables were spirometry and diffusing capacity for carbon monoxide; explanatory variables were inflammatory biomarkers (interleukin-6, tumor necrosis factor-alpha), bacterial translocation (soluble CD14 [sCD14] and bacterial 16S rDNA), and variables related to HIV infection. Associations were tested using the Pearson/Spearman correlation tests, the Student t-test, and multivariable linear regression. RESULTS We included 71 patients (54.9% smokers). We did not observe significant differences in pulmonary function tests according to biomarkers of inflammation or bacterial translocation. In non-smokers (n=32), sCD14 was negatively correlated with forced expiratory volume in 1 second (R = -0.35, P = 0.048) and forced vital capacity (R= -0.40, P=0.023). Age, time since HIV diagnosis, and CD4+ nadir were associated with alterations in PFTs. In smokers, the only association observed was between the pack-years and pulmonary obstruction. CONCLUSION In non-smokers, HIV patients' lung dysfunction can be, at least partially, related to bacterial translocation (sCD14), CD4+ nadir, and time since HIV diagnosis.

Abstract
The high cost of fidaxomicin has restricted its use despite the benefit of a lower Clostridioides difficile infection (CDI) recurrence rate at 4 weeks of follow-up. This short follow-up represents the main limitation of pivotal clinical trials of fidaxomicin, and some recent studies question its benefits over vancomycin. Moreover, the main risk factors of recurrence after treatment with fidaxomicin remain unknown. We designed a multicentre retrospective cohort study among four Spanish hospitals to assess the efficacy of fidaxomicin in real life and to investigate risk factors of fidaxomicin failure at weeks 8 and 12. Two-hundred forty-four patients were included. Fidaxomicin was used in 96 patients (39.3%) for a first episode of CDI, in 95 patients (38.9%) for a second episode, and in 53 patients (21.7%) for a third or subsequent episode. Patients treated with fidaxomicin in a first episode were younger (59.9 years vs 73.5 years), but they had more severe episodes (52.1% vs. 32.4%). The recurrence rates for patients treated in the first episode were 6.5% and 9.7% at weeks 8 and 12, respectively. Recurrence rates increased for patients treated at second or ulterior episodes (16.3% and 26.4% at week 8, respectively). Age greater than or equal to 85 years and having had a previous episode of CDI were identified as recurrence risk factors at weeks 8 and 12. We conclude that the outcomes with fidaxomicin in real life are at least as good as those observed in clinical trials despite a more demanding evaluation. Be it 85 years of age or older, and the use after a first episode appears to be independent factors of CDI recurrence after treatment with fidaxomicin.

Abstract
AIM To explore a set of inflammatory biomarkers obtained from dentinal fluid (DF) from patients with symptomatic irreversible pulpitis (IP), reversible pulpitis (RP) and normal pulp (NP). METHODOLOGY A cross-sectional exploratory study was performed, recruiting 64 patients on the basis of their respective pulp condition. DF samples were obtained from all patients (23, from IP patients; 20, from RP patients; and 21, from NP patients). Quantification of biomarkers was performed using a Luminex® MAGPIX platform system and multiplex assay kits. The Kruskal-Wallis test was used for comparisons with regard to pulp state. A simple logistic regression model and the odds ratio (OR) with a 95% level of confidence (P = 0.05) were used to evaluate associations between biomarker levels and pulpal diagnosis. The performance discrimination of the biomarkers was evaluated through the construction of a receiver operating characteristic (ROC) curve by calculating the area under the curve (AUC) for IP versus RP after logistic regression modelling. Youden criteria were used to establish cut-off points for biomarkers alone with AUC > 70 and P-value < 0.05, or estimated probabilities from the multivariable logistic model. RESULTS The biomarkers that had significantly higher values in participants with IP versus RP were IL-1α, VEGF-α and FGF acid (P < 0.05). FGF acid (OR: 12.62; P = 0.0085; CI 95% 1.91-83.29) and VEGF-α (OR: 2.61; P = 0.0252; CI 95% 1.13-6.03) were associated with pulp diagnoses of IP versus RP. The AUC-ROC curve for FGF acid was 0.79. The model containing FGF acid, IL-1α, IL-6 and TIMP-1 had an AUC-ROC of 0.92 for IP versus RP with a significant difference from the FGF acid ROC curve (P = 0.0231). CONCLUSIONS Dentinal fluid could be used to assay pulpal mediators in the molecular diagnosis of pulpitis. Despite the limitation of the clinical diagnostics used in the present study, it was possible to detect a difference between irreversible symptomatic pulpitis and reversible pulpitis associated with the following combined biomarkers: FGF acid + IL-6 + IL-1α, +TIMP-1.

Abstract
BACKGROUND The aim of this study was to investigate the effectiveness and tolerability of the combination elvitegravir/cobicistat/tenofovir/emtricitabine plus darunavir (EVG/COB/TFV/FTC + DRV) in treatment-experienced patients from the cohort of the Spanish HIV/AIDS Research Network (CoRIS). METHODS Treatment-experienced patients starting treatment with EVG/COB/TFV/FTC + DRV during the years 2014-2018 and with more than 24 weeks of follow-up were included. TFV could be administered either as tenofovir disoproxil fumarate or tenofovir alafenamide. We evaluated virological response, defined as viral load (VL) < 50 copies/ml and < 200 copies/ml at 24 and 48 weeks after starting this regimen, stratified by baseline VL (< 50 or ≥ 50 copies/ml at the start of the regimen). RESULTS We included 39 patients (12.8% women). At baseline, 10 (25.6%) patients had VL < 50 copies/ml and 29 (74.4%) had ≥ 50 copies/ml. Among patients with baseline VL < 50 copies/ml, 85.7% and 80.0% had VL < 50 copies/ml at 24 and 48 weeks, respectively, and 100% had VL < 200 copies/ml at 24 and 48 weeks. Among patients with baseline VL ≥ 50 copies/ml, 42.3% and 40.9% had VL < 50 copies/ml and 69.2% and 68.2% had VL < 200 copies/ml at 24 and 48 weeks. During the first 48 weeks, no patients changed their treatment due to toxicity, and 4 patients (all with baseline VL ≥ 50 copies/ml) changed due to virological failure. CONCLUSIONS EVG/COB/TFV/FTC + DRV was well tolerated and effective in treatment-experienced patients with undetectable viral load as a simplification strategy, allowing once-daily, two-pill regimen with three antiretroviral drug classes. Effectiveness was low in patients with detectable viral loads.

Abstract
OBJECTIVE HIV infection is associated with an increased risk of cardiovascular disease. Irisin is a miokyne secreted by skeletal muscle, which may influence insulin homeostasis, nonalcoholic fatty liver disease (NAFLD) and atherosclerosis. Our objective was to evaluate the relationships between serum irisin, insulin homeostasis, NAFLD and subclinical atherosclerosis in HIV-infected males. DESIGN Cross-sectional study in a cohort of HIV-infected patients. PATIENTS Inclusion criteria: men older than 18 years; antiretroviral therapy (ART) -naïve or on effective ART (<50 HIV-1 RNA copies/mL) without changes in the previous 6 months; no diabetes or hepatitis C. MEASUREMENTS Irisin was measured by enzymatic immunoassay (Phoenix Pharmaceuticals), insulin sensitivity by homeostasis model assessment of insulin resistance (HOMA-IR), as well as the 2-hour continuous infusion of glucose with model assessment (CIGMA-HOMA). Hepatic steatosis was measured by 1-H magnetic resonance spectroscopy, subclinical atherosclerosis by evaluation of carotid intima-media thickness (C-IMT), measured by Ultrasonography. RESULTS Eight nine men (age 42.0 ± 8.3 years, duration of HIV infection 7.9 ± 5.6 years, CD4 count 547 ± 279 cells/mL) were included. Circulating irisin was positively related to HOMA-IR and CIGMA-HOMA, hepatic triglyceride content, and to VAT/SAT ratio. Higher irisin concentrations were associated with higher C-IMT, although this association did not persist in multivariate analysis. Lipodystrophy and a higher baseline PAI-1 concentration were independently associated with C-IMT. CONCLUSIONS In male HIV patients without diabetes, higher irisin concentrations are positively associated with insulin resistance, NAFLD and subclinical atherosclerosis. However, waist-hip-ratio is the main determinant of insulin resistance, and PAI-1 and lipodystrophy were the strongest determinants of IMT in this population.

Abstract
A fast and automated scheme for general polarization transformations holds great value in adaptive optics, quantum information, and virtually all applications involving light-matter and light-light interactions. We present an experiment that uses a liquid crystal on silicon spatial light modulator to perform polarization transformations on a light field. We experimentally demonstrate the point-by-point conversion of uniformly polarized light fields across the wavefront to realize arbitrary, spatially varying polarization states. Additionally, we demonstrate that a light field with an arbitrary spatially varying polarization can be transformed to a spatially invariant (i.e., uniform) polarization.

Abstract
In HIV-infected patients, the damage in the gut mucosal immune system is not completely restored after antiretroviral therapy (ART). It results in microbial translocation, which could influence the immune and inflammatory response. We aimed at investigating the long-term impact of bacterial-DNA translocation (bactDNA) on glucose homeostasis in an HIV population. This was a cohort study in HIV-infected patients whereby inclusion criteria were: patients with age >18 years, ART-naïve or on effective ART (<50 HIV-1 RNA copies/mL) and without diabetes or chronic hepatitis C. Primary outcome was the change in HbA1c (%). Explanatory variables at baseline were: bactDNA (qualitatively detected in blood samples by PCR [broad-range PCR] and gene 16SrRNA - prokaryote), ART exposure, HOMA-R and a dynamic test HOMA-CIGMA [continuous infusion of glucose with model assessment], hepatic steatosis (hepatic triglyceride content - 1H-MRS), visceral fat / subcutaneous ratio and inflammatory markers. Fifty-four men (age 43.2 ± 8.3 years, BMI 24.9 ± 3 kg/m2, mean duration of HIV infection of 8.1 ± 5.3 years) were included. Baseline HbA1c was 4.4 ± 0.4% and baseline presence of BactDNA in six patients. After 8.5 ± 0.5 years of follow-up, change in HbA1c was 1.5 ± 0.47% in patients with BactDNA vs 0.87 ± 0.3% in the rest of the sample p < 0.001. The change in Hba1c was also influenced by protease inhibitors exposure, but not by baseline indices of insulin resistance, body composition, hepatic steatosis, inflammatory markers or anthropometric changes. In non-diabetic patients with HIV infection, baseline bacterial translocation and PI exposure time were the only factors associated with long-term impaired glucose homeostasis.

Abstract
In a classical world, simultaneous measurements of complementary properties (e.g., position and momentum) give a system's state. In quantum mechanics, measurement-induced disturbance is largest for complementary properties and, hence, limits the precision with which such properties can be determined simultaneously. It is tempting to try to sidestep this disturbance by copying the system and measuring each complementary property on a separate copy. However, perfect copying is physically impossible in quantum mechanics. Here, we investigate using the closest quantum analog to this copying strategy, optimal cloning. The coherent portion of the generated clones' state corresponds to "twins" of the input system. Like perfect copies, both twins faithfully reproduce the properties of the input system. Unlike perfect copies, the twins are entangled. As such, a measurement on both twins is equivalent to a simultaneous measurement on the input system. For complementary observables, this joint measurement gives the system's state, just as in the classical case. We demonstrate this experimentally using polarized single photons.

Abstract
BACKGROUND Pathogenesis of atherosclerosis is complex, and differences between HIV-infected patients and general population cannot be completely explained by the higher prevalence of traditional cardiovascular risk factors. We aimed to analyse the association between inflammation and subclinical atherosclerosis in HIV patients with low Framingham risk score. MATERIALS AND METHODS Case-control study. SETTING Outpatient Infectious Diseases clinic in a university hospital. SUBJECTS HIV-1-infected patients aged > 35 years receiving antiretroviral treatment with viral load < 50 copies/mL and Framingham risk score < 10%. EXCLUSION CRITERIA inflammatory diseases; dyslipidaemia requiring statins; smoking > 5 cigarettes/day; diabetes; hypertension; vascular diseases. MAIN OUTCOME subclinical atherosclerosis determined by ultrasonography: common carotid intima-media thickness greater than 0·8 mm or carotid plaque presence. Explanatory variables: ribosomal bacterial DNA (rDNA), sCD14, interleukin-6 (IL-6) and TNF-α. RESULTS Eighty-four patients were included, 75% male, mean age 42 years and mean CD4+ cells 657 ± 215/mm3 . Median Framingham risk score was 1% at 10 years (percentile 25-75: 0·5-4%). Eighteen patients (21%) had subclinical atherosclerosis; the associated factors were older age (P = 0·001), waist-hip ratio (P = 0·01), time from HIV diagnosis (P = 0·02), rDNA (P = 0·04) and IL-6 (P = 0·01). In multivariate analysis, OR for subclinical atherosclerosis was 7 (95% CI, 1.3-40, P = 0.02) and 9 (95% CI, 1.0-85, P = 0.04) for patients older than 44 years and IL-6 > 6·6 pg/mL, respectively. CONCLUSIONS Well-controlled HIV patients with low Framingham risk score have a high prevalence of subclinical carotid atherosclerosis, and the main risk factors are age and inflammation. These patients are not receiving primary prophylaxis for cardiovascular events according to current guidelines.

Abstract
The aim of this study is to examine the reproductive history of human immunodeficiency virus (HIV)-positive women, before and after HIV diagnosis, to describe the characteristics of women with pregnancies after HIV diagnosis, and to assess the prevalence of mother-to-child transmission.A cross-sectional study was performed among women within reproductive ages (18-49) selected from the cohort in the Spanish AIDS Research Network (CoRIS). A descriptive analysis of the pregnancy outcomes was made according to women's serostatus at the moment of pregnancy and association of women's characteristics with having pregnancy after HIV diagnosis was evaluated using logistic regression models.Overall, 161 women were interviewed; of them, 86% had been pregnant at least once and 39% after HIV diagnosis. There were 347 pregnancies, 29% of them occurred after HIV diagnosis and in these, 20% were miscarriages and 29% were voluntary termination of pregnancy. There were 3 cases of mother-to-child transmission among the 56 children born from HIV-positive mothers; in these cases, women were diagnosed during delivery. Having a pregnancy after HIV diagnosis was more likely when the younger women were at the time of diagnosis: odds ratio (OR) = 1.29 (95% confidence interval 0.40-4.17) for 25 to 29 years old, OR = 0.59 (0.15-2.29) for 30 to 34 years old, OR = 0.14 (0.03-0.74) for ≥35 years old, compared with those <25 years at diagnosis, who were diagnosed for ≥5 years (OR = 5.27 [1.71-16.18]), who received antiretroviral treatment at some point (OR = 9.38 [1.09-80.45]), and who received information on reproductive health (OR = 4.32 [1.52-12.26]).An important number of pregnancies occurred after HIV diagnosis, reflecting a desire for motherhood in these women. Reproductive and sexual health should be tackled in medical follow-ups.

Abstract
One drawback of conventional quantum state tomography is that it does not readily provide access to single density matrix elements since it requires a global reconstruction. Here, we experimentally demonstrate a scheme that can be used to directly measure individual density matrix elements of general quantum states. The scheme relies on measuring a sequence of three observables, each complementary to the last. The first two measurements are made weak to minimize the disturbance they cause to the state, while the final measurement is strong. We perform this joint measurement on polarized photons in pure and mixed states to directly measure their density matrix. The weak measurements are achieved using two walk-off crystals, each inducing a polarization-dependent spatial shift that couples the spatial and polarization degrees of freedom of the photons. This direct measurement method provides an operational meaning to the density matrix and promises to be especially useful for large dimensional states.

Abstract
IntroductionIt has been suggested that there is a relationship between BMI and suicide. Thus, BMI of subjects who commit suicide would be lower than the BMI of other unnatural deaths (Flaig 2013).ObjectivesExplore the possible relationship between BMI and suicide.Material and methodsA total of 1197 suicides and 473 unnatural deaths (not by suicide) were collected systematically for 60 months at the Institute of Legal Medicine of Seville. Age, sex, weight, height and cause of death were recorded. Statistical analysis was performed using SPSS v19.0.Results(Figure 1)DiscussionIn our study we found that suicide (of all age groups and both sexes) have a lower BMI than controls. However, the relationship between these two variables is complex and not all studies support it. Moreover, the relationships between depression, suicide and overweight point in different directions. More and more studies indicate the existence of a relationship between depression and overweight, suggesting that perhaps the “epidemic” of depression and overweight that we see in Western societies has some connection. In addition, depression is a risk factor for suicide well established. Our results indicate that suicide group tends to have lower BMI (less weight in relation to its size) than the controls.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionPsychological autopsy studies have constantly indicated a clear relation between mental disorders and suicide. This relation has been found in studies across the world, although the percentage of cases with at least one mental disorder diagnosed may vary between studies and specially, between countries and geographical regions.MethodsReview of psychological autopsy studies of suicide completers which contained information on diagnostic distribution. Only studies carried out in Europe and North America were included.ResultsA total of 14 studies, including 1519 suicides, were analyzed (Table 1).ConclusionsSuicide risk is a multifactor phenomenon, however, it is strongly related to mental disorders. Mental health strategies should be directed to target clinical groups at high risk of suicide.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
OBJECTIVES Inhibin B (IB) levels and the IB: follicle-stimulating hormone (FSH) ratio (IFR), biomarkers of global Sertoli cell function, show a strong relationship with male fertility. The aim of the study was to examine the prevalence of impaired fertility potential in HIV-infected men and the influence of antiretroviral therapy (ART) on fertility biomarkers. METHODS A cross-sectional study with sequential sampling was carried out. A total of 169 clinically stable patients in a cohort of HIV-infected men undergoing regular ambulatory assessment in a tertiary hospital were included. The mean [± standard deviation (SD)] age of the patients was 42.6 ± 8.1 years, all were clinically stable, 61.5% had disease classified as Centers for Disease Control and Prevention (CDC) stage A, and were na?ve to ART or had not had any changes to ART for 6 months (91.1%). Morning baseline IB and FSH concentrations were measured using an enzyme-linked immunosorbent assay (ELISA) and an electrochemiluminescent immunoassay (ECLIA), respectively. A multivariate logistic regression model was used to identify factors associated with impaired fertility, defined as IB < 119 pg/mL or IFR < 23.5. RESULTS The mean (± SD) IB level was 250 ± 103 pg/mL, the median [interquartile range (IQR)] FSH concentration was 5.1 (3.3-7.8) UI/L and the median (IQR) IFR was 46.1 (26.3-83.7). The prevalence of impaired fertility was 21.9% [95% confidence interval (CI) 16.3-20.7%]. Negative correlations of body mass index and waist: hip ratio with FSH and IB levels were observed (P < 0.01), while a sedentary lifestyle and previous nevirapine exposure were associated with a decreased risk of IB levels ≤ 25th percentile in multivariate analysis. Only older age, as a risk factor, and sedentary lifestyle, with a protective effect, were independently associated with impaired fertility in multivariate analysis. CONCLUSIONS Global testicular Sertoli cell function and fertility potential, assessed indirectly through serum IB levels and IB: FSH ratio, appear to be well maintained in HIV-infected men and not damaged by ART.

Abstract
We report on an experiment in which orbital angular momentum (OAM) of light is mapped at the single-photon level into and out of a cold atomic ensemble. Based on the dynamic electromagnetically induced transparency protocol, the demonstrated optical memory enables the reversible mapping of Laguerre-Gaussian modes with preserved handedness of the helical phase structure. The demonstrated capability opens the possibility to the storage of qubits encoded as superpositions of OAM states and to multidimensional light matter interfacing.

Abstract
Potent stem/progenitor cells have been isolated from normal human dental pulps, termed dental pulp stem cells (DPSCs). However, no study has described the presence of stem cell populations in human dental pulp from the third molar with embryonic phenotypes. The dental pulp tissue was cultured in media with the presence of LIF, EGF, and PDGF. In the present study, we describe a new population of pluripotent stem cells that were isolated from dental pulp (DPPSC). These cells are SSEA-4(+), Oct4(+), Nanog(+), FLK-1(+), HNF3beta(+), Nestin(+), Sox2(+), Lin28(+), c-Myc(+), CD13(+), CD105(+), CD3(-), CD45(-), CD90(low), CD29(+), CD73(low), STRO-1(low) and CD146(-). We have investigated by SEM analysis and q-RT-PCR the capacity of DPPSCs to 3D differentiate in vitro using the Cell Carrier 3D glass scaffold into tissues that have similar characteristics to embryonic mesoderm and endoderm layers. These data would support the use of these cells, which are derived from an easily accessible source and can be used in future regeneration protocols for many tissue types that differentiate from the three embryonic layers.

Abstract
OBJECTIVES To evaluate the liver safety of raltegravir-including combinations in HIV/hepatitis C virus (HCV) co-infected patients. METHODS Grade 3-4 transaminase elevations (TEs) and grade 4 total bilirubin elevations (TBEs) were assessed during 12 months in 108 HIV/HCV co-infected patients starting antiretroviral therapy including raltegravir in a retrospective cohort study. Furthermore, the relationship between baseline fibrosis and hepatotoxic events was determined. RESULTS Eight patients (7.4%) developed grade 3 TEs and two (1.9%) patients showed grade 4 TEs. TBE grade 4 was detected in two (1.9%) patients. No patient permanently discontinued raltegravir because of hepatotoxic events. Of the patients with and without significant fibrosis, six (9.4%) and two (11.8%), respectively, showed grade 3-4 TEs (P = 0.769). Grade 3-4 TEs was observed in four (9.8%) patients in whom cirrhosis was ruled out, while none of the patients diagnosed with cirrhosis developed grade 3-4 TEs (P = 0.303). During the follow-up, the median (Q1-Q3) CD4 cell count increased from 257 (145-421) cells/mm(3) to 407 (213-587) cells/mm(3) (P < 0.0001) and the number of patients with an undetectable HIV viral load augmented from 33 (30.6%) to 73 (81.1%) (P = 0.002). CONCLUSIONS Raltegravir-containing regimens are safe in HIV/HCV co-infected patients. The incidence of severe liver toxicity of raltegravir in these individuals is in the range of boosted protease inhibitors in clinical trials. The frequencies of grade 3-4 TEs and grade 4 TBEs were similar in patients receiving raltegravir with or without significant fibrosis or cirrhosis.

Abstract
The corrosion of five materials for implant suprastructures (cast-titanium, machined-titanium, gold alloy, silver-palladium alloy and chromium-nickel alloy), was investigated in vitro, the materials being galvanically coupled to a titanium implant. Various electrochemical parameters E(CORR), i(CORR) Evans diagrams, polarization resistance and Tafel slopes) were analyzed. The microstructure of the different dental materials was observed before and after corrosion processes by optical and electron microscopy. Besides, the metallic ions released in the saliva environment were quantified during the corrosion process by means of inductively coupled plasma-mass spectrometry technique (ICP-MS). The cast and machined titanium had the most passive current density at a given potential and chromium-nickel alloy had the most active critical current density values. The high gold content alloys have excellent resistance corrosion, although this decreases when the gold content is lower in the alloy. The palladium alloy had a low critical current density due to the presence of gallium in this composition but a selective dissolution of copper-rich phases was observed through energy dispersive X-ray analysis.

Abstract
In this work the metallic ion release in oral implants with superstructures of different metals and alloys used in clinical dentistry has been determined. This study has been realized in a saliva environment at 37 degrees C. The measurements of the ion release were carried out by means of the Inductively Coupled Plasma Mass Spectrometry technique. The titanium oral implant coupled with a chromium-nickel alloy releases a high quantity of ions and the implant coupled with the titanium superstructure presents a low value of ion release.
