Abstract
OBJECTIVE To compare 48-week changes in bone mineral density (BMD) and body fat distribution between patients continuing lopinavir/ritonavir and two NRTIs and those switching to lopinavir/ritonavir and lamivudine. METHODS Substudy of a randomized, open-label, multicenter OLE study was carried out. Adult HIV-infected patients with <50 copies/mL for ≥6 months were randomized (1:1) to continue lopinavir/ritonavir and two NRTIs or switching to lopinavir/ritonavir and lamivudine. Dual-energy X-ray absorptiometry (DXA) was performed at baseline and after 48 weeks to measure bone composition and body fat distribution in both the groups. RESULTS Forty-one patients (dual-therapy, n = 23; triple-therapy, n = 18) of 239, who received at least one dose of study medication, completed the study: median age, 42 years, 71% male, 73% Caucasian. At week 48, total BMD increased by 1.04% (95% CI, 0.06 to 2.01%) among patients switching to dual-therapy, whereas no significant changes occurred in patients maintaining triple-therapy. Dual-therapy and older age were independently associated with total BMD increase. Among patients discontinuing tenofovir-DF, a significant increase was seen in total BMD (1.43; 95% CI, -0.04 to 2.91) and total hip (1.33%; 95% CI, 0.44 to 2.22%). A non-statistically significant decrease in femoral and spinal BMD was observed in patients who discontinued abacavir and in those continuing triple-therapy. Regarding fat distribution, no significant changes were seen in both the treatment groups. DISCUSSION BMD increased following switching to lopinavir/ritonavir plus lamivudine in HIV-infected patients on suppressive triple-therapy with lopinavir/ritonavir and two NRTIs including tenofovir-DF.

Abstract
IntroductionNarrative studies have focused on the language used by the individuals to describe stressful or traumatic experiences. Hence, linguistic procedures have been applied aiming to obtain information about autobiographical memories and trauma processing. However, there is a general lack of agreement about how to measure narrative aspects. Software programs for this purpose are limited, since they don’t capture the language context, and systems based on judge's rates are not free of subjective biases.ObjectivesThis study presents a coding system developed to analyze several language categories related to traumatic memories and psychological processes. Structural aspects (e.g., coherence) and content dimensions of traumatic narratives (e.g., emotional or cognitive processes) are measured. Each narrative aspect is coded by raters using both dichotomous (presence/absence) and numerical values (Likert scale).AimsTo propose a structured coding system for traumatic narratives that considers the language context and maximizes consensus among different raters.MethodsTraumatic narratives from 50 traumatized women and stressful narratives from 50 non-traumatized women have been evaluated according the system developed. Three blind raters coded each narrative.ResultsInter-rater reliability data are provided for the different narrative categories. The agreement between raters is discussed for both structural and content language domains.ConclusionsThe analysis of the inter-rater reliability allows exploring subjective biases in assessing different structural and content language dimensions. This study advances in the development of a procedure to analyze autobiographical narratives in a valid and reliable way, with a special focus on traumatic and other unpleasant memories.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionQuality of Life (QoL) is an important outcome variable in Methadone Maintenance Treatment (MMT) for opiate dependence. Previous research has focused on demographic variables, treatment features, drug use and physical and mental health as possible predictors of QoL in this condition but interest in genuinely psychological variables (skills and personal repertoires) has been lacking. Experiential Avoidance (EA), the tendency to behave in order to decrease some kind of internal distress, has a strong relationship to psychological disorders and holds promise as a potential predictor of QoL.ObjectivesTo identify predictors of QoL in clients undergoing MMT, taking into account psychological variables.AimsTo see if EA is related to QoL in clients undergoing MMT.MethodsUsing a cross-sectional design, information was gathered from 48 opiate-dependent individuals undergoing MMT. Variables included were QoL (IDUQOL), severity of drug use, social adjustment and physical and mental health (ASI-6), emotional distress (HAD) and EA (AAQ and its version for substance-abusing individuals, AAQ-SA). Mean-comparison tests and correlation tests were carried out, and several variables were entered into a stepwise multiple regression analysis.ResultsAnxiety and EA were the only variables which made it into the regression model, accounting for 41.9% of variance of QoL.ConclusionsContrary to previous research, the predictors of QoL were psychological. It is the first time that EA is related to QoL in this population. Interventions should explicitly target EA and anxiety. Additional research should make use of longitudinal designs and take into account further psychological variables (emotion regulation, coping).Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionTrauma narratives contain a lot of emotion words, in comparison with narratives about other autobiographical memories. Negative emotion's words, as well as words about death (as an indicator of threat perception), have been associated to a worse adjustment after trauma. However, the different kind of negative emotions reported have been rarely explored. Also, in violence victims, the use of words about abuse might indicate threat perception.ObjectivesAnalyzing the use of negative words and threat perception (death and abuse words) in trauma narratives from 50 battered women, compared with stressful narratives from 50 non-traumatized women, and positive narratives. The relationship between narratives aspects and symptomatology is explored.AimsExploring differences in emotions and threat perception related to psychological functioning after trauma.MethodsBattered women were asked to remember the worst violence episode, whereas non-traumatized women narrated their most stressful experience. Both groups remembered also a neutral and a positive episode. LIWC software was used to calculate the percentage of different words used.ResultsAnger was the most used negative emotion. Anger and sadness words were more reported in stressful and trauma narratives than in positive ones. There were differences between groups in the use of death and abuse words. Anger and abuse words were associated to anxiety and depression, but not PTSD symptoms. Death words were related to a better functioning.ConclusionsThis study evidences the need to explore the role of different negative emotions in the posttraumatic adaptation. Also contextual aspects involved on threat perception must be considered.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Mango malformation disease (MMD) has become an important global disease affecting this crop. The aim of this study was to identify the main causal agents of MMD in the Axarquía region of southern Spain and determine their genetic diversity. Fusarium mangiferae was previously described in the Axarquía region but it represented only one-third of the fusaria recovered from malformed trees. In the present work, fusaria associated with MMD were analyzed by arbitrary primed polymerase chain reaction (ap-PCR), random amplified polymorphic DNA (RAPD), vegetative compatibility grouping (VCG), a PCR screen for mating type idiomorph, and phylogenetic analyses of multilocus DNA sequence data to identify and characterize the genetic diversity of the MMD pathogens. These analyses confirmed that 92 of the isolates were F. tupiense, which was previously only known from Brazil and Senegal. In addition, two isolates of a putatively novel MMD pathogen were discovered, nested within the African clade of the Fusarium fujikuroi species complex. The F. tupiense isolates all belonged to VCG I, which was first described in Brazil, and the 11 isolates tested showed pathogenicity on mango seedlings. Including the prior discovery of F. mangiferae, three exotic MMD pathogenic species have been found in southern Spain, which suggests multiple independent introductions of MMD pathogens in the Axarquía region.

Abstract
OBJECTIVES Electrocautery is one of the main treatment options for high-grade anal intraepithelial neoplasia (HGAIN). However, data regarding its efficacy are scarce. The aim of the study was to evaluate the effectiveness of electrocautery for the treatment of HGAIN. METHODS An observational study of HIV-infected men who have sex with men (MSM) who underwent screening for anal dysplasia was carried out. The on-treatment effectiveness of electrocautery was evaluated (according to biopsy findings measured 6-8 weeks after treatment) in patients with HGAIN. A complete response was defined as resolution of anal intraepithelial neoplasia (AIN), a partial response as regression to low-grade AIN and recurrence as biopsy-proven HGAIN during follow-up. RESULTS From May 2009 to November 2014, 21.9% (126 of 576) of patients screened were found to have HGAIN. Electrocautery effectiveness was evaluated in 83 patients. A complete response was observed in 27 patients [32.5%; 95% confidence interval (CI) 23.4-53.2%], a partial response in 28 patients (33.7%; 95% CI 24.5-44.4%) and persistence in 28 patients (33.7%; 95% CI 24.5-44.4%). The patients with the most successful results (81.8%) required two to four sessions of electrocautery. After a mean follow-up of 12.1 months, 14 of 55 patients with a response (25.4%; 95% CI 15.8-38.3%) developed recurrent HGAIN within a mean time of 29.9 months (95% CI 22-37.7 months). No patient progressed to invasive cancer during the study or developed serious adverse events after treatment. No factors associated with poor response or recurrences were observed. CONCLUSIONS Although electrocautery is the standard treatment for anal dysplasia, almost 50% of patients with HGAIN in our study did not respond or relapsed. New treatment strategies are necessary to optimize the management of anal dysplasia.

Abstract
BACKGROUND AZD3514 is a first-in-class, orally bio-available, androgen-dependent and -independent androgen receptor inhibitor and selective androgen-receptor down-regulator (SARD). METHODS In study 1 and 2, castration-resistant prostate cancer (CRPC) patients (pts) were initially recruited into a once daily (QD) oral schedule (A). In study 1, pharmacokinetic assessments led to twice daily (BID) dosing (schedule B) to increase exposure. Study 2 explored a once daily schedule. RESULTS In study 1, 49 pts were treated with escalating doses of AZD3514 (A 35 pts, B 14 pts). Starting doses were 100 mg (A) and 1000 mg (B). The AZD3514 formulation was switched from capsules to tablets at 1000 mg QD. 2000 mg BID was considered non-tolerable due to grade (G) 2 toxicities (nausea [N], vomiting [V]). No adverse events (AEs) met the dose-limiting toxicity (DLT) definition. Thirteen pts received AZD3514 in study 2, with starting doses of 250 mg QD. The most frequent drug-related AEs were N: G1/2 in 55/70 pts (79 %); G3 in 1 pt (1.4 %); & V: G1/2 in 34/70 pts (49 %) & G3 in 1 pt (1.4 %). PSA declines (≥50 %) were documented in 9/70 patients (13 %). Objective soft tissue responses per RECIST1.1 were observed in 4/24 (17 %) pts in study 1. CONCLUSION AZD3514 has moderate anti-tumour activity in pts with advanced CRPC but with significant levels of nausea and vomiting. However, anti-tumour activity as judged by significant PSA declines, objective responses and durable disease stabilisations, provides the rationale for future development of SARD compounds.

Abstract
BACKGROUND Abiraterone and enzalutamide are novel endocrine treatments that abrogate androgen receptor (AR) signalling in castration-resistant prostate cancer (CRPC). Here, we developed a circulating tumour cells (CTCs)-based assay to evaluate AR expression in real-time in CRPC and investigated nuclear AR expression in CTCs in patients treated with enzalutamide and abiraterone. METHODS CTCs were captured and characterised using the CellSearch system. An automated algorithm to identify CTCs and quantify AR expression was employed. The primary aim was to evaluate the association between CTC AR expression and prior treatment with abiraterone or enzalutamide. RESULTS AR expression in CTCs was evaluated in 94 samples from 48 metastatic CRPC patients. We observed large intra-patient heterogeneity of AR expression in CTCs. Prior exposure to abiraterone or enzalutamide was not associated with a change in CTCs AR expression (median intensity and distribution of AR-positive classes). In support of this, we also confirmed maintained nuclear AR expression in tissue samples collected after progression on abiraterone. AR staining also identified additional AR-positive CD45-negative circulating cells that were CK-negative/weak and therefore missed using standard protocols. The number of these events correlated with traditional CTCs and was associated with worse outcome on univariate analysis. CONCLUSIONS We developed a non-invasive method to monitor AR nuclear expression in CTCs. Our studies confirm nuclear AR expression in CRPC patients progressing on novel endocrine treatments. Owing to the significant heterogeneity of AR expression in CTCs, studies in larger cohorts of patients are required to identify associations with outcome.

Abstract
Detection of posttransplant donor-specific anti-HLA antibodies (DSA) constitutes a risk factor for kidney allograft loss. Together with complement activation, NK-cell antibody-dependent cell mediated cytotoxicity (ADCC) has been proposed to contribute to the microvascular damage associated to humoral rejection. In the present observational exploratory study, we have tried to find a relationship of circulating donor-specific and non donor-specific anti-HLA antibodies (DSA and HLA non-DSA) with peripheral blood NK-cell subsets and clinical features in 393 renal allograft recipients. Multivariate analysis indicated that retransplantation and pretransplant sensitization were associated with detection of posttransplant DSA. Recipient female gender, DR mismatch and acute rejection were significantly associated with posttransplant DSA compared to HLA non-DSA. In contrast with patients without detectable anti-HLA antibodies, DSA and HLA non-DSA patients displayed lower proportions of NK-cells, associated with increased CD56(bright) and NKG2A(+) subsets, the latter being more marked in DSA cases. These differences appeared unrelated to retransplantation, previous acute rejection or immunosuppressive therapy. Although preliminary and observational in nature, our results suggest that the assessment of the NK-cell immunophenotype may contribute to define signatures of alloreactive humoral responses in renal allograft recipients.

Abstract
OBJECTIVES The aim of the study was to investigate liver fibrosis outcome and the risk factors associated with liver fibrosis progression in hepatitis C virus (HCV)/HIV-coinfected patients. METHODS We prospectively obtained liver stiffness measurements by transient elastography in a cohort of 154 HCV/HIV-coinfected patients, mostly Caucasian men on suppressive antiretroviral treatment, with the aim of determining the risk for liver stiffness measurement (LSM) increase and to identify the predictive factors for liver fibrosis progression. To evaluate LSM trends over time, a linear mixed regression model with LSM level as the outcome and duration of follow-up in years as the main covariate was fitted. RESULTS After a median follow-up time of 40 months, the median increase in LSM was 1.05 kPa/year [95% confidence interval (CI) 0.72-1.38 kPa/year]. Fibrosis stage progression was seen in 47% of patients, and 17% progressed to cirrhosis. Aspartate aminotransferase (AST) levels and liver fibrosis stage at baseline were identified as independent predictors of LSM change. Patients with F3 (LSM 9.6-14.5 kPa) or AST levels ≥ 64 IU/L at baseline were at higher risk for accelerated LSM increase (ranging from 1.45 to 2.61 kPa/year), whereas LSM change was very slow among patients with both F0-F1 (LSM ≤ 7.5 kPa) and AST levels ≤ 64 IU/L at baseline (0.34 to 0.58 kPa/year). An intermediate risk for LSM increase (from 0.78 to 1.03 kPa/year) was seen in patients with F2 (LSM 7.6-9.5 kPa) and AST baseline levels ≤ 64 IU/L. CONCLUSIONS AST levels and liver stiffness at baseline allow stratification of the risk for fibrosis progression and might be clinically useful to guide HCV treatment decisions in HIV-infected patients.

Abstract
Metastatic involvement of the viscera in men with advanced castration-resistant prostate cancer (CRPC) has been poorly characterised to date. In 359 CRPC patients treated between June 2003 and December 2011, the frequency of radiologically detected visceral metastases before death was 32%. Of the 92 patients with computed tomography performed within 3 mo of death, 49% had visceral metastases. Visceral metastases most commonly involved the liver (20%) and lung (13%). Median survival from diagnosis of visceral disease was 7.1 mo (95% confidence interval, 5.9-8.3). Survival was affected by the degree of bone involvement at detection of visceral disease, varying from 6.1 mo in men with more than six bone metastases to 18.2 mo in men with no bone metastases (p=0.001). Heterogeneity was noted in clinical phenotypes and prostate-specific antigen trends at development of visceral metastases. Visceral metastases are now more commonly detected in men with CRPC, likely due to the introduction of novel survival-prolonging treatments.
