Abstract
Racial and ethnic disparities in substance use intervention design, implementation, and dissemination have been recognized for years, yet few intervention programs have been designed and conducted by and for people who use substances. Imani Breakthrough is a two-phase 22-week intervention developed by the community, run by facilitators with lived experience and church members, that is implemented in Black and Latinx church settings. This community-based participatory research (CBPR) approach is a concept developed in response to a call for action from the State of Connecticut Department of Mental Health and Addiction Services (DMHAS) with funding from the Substance Abuse and Mental Health Services Administration (SAMHSA) to address rising rates of death due to opioid overdose, and other negative consequences of substance misuse. After nine months of didactic community meetings, the final design involved twelve weeks of education in a group setting related to the recovery process, including the impact of trauma and racism on substance use, and a focus on citizenship and community participation and the 8 dimensions of wellness, followed by ten weeks of mutual support, with intensive wraparound support and life coaching focused on the social determinants of health (SDOH). We found the Imani intervention was feasible and acceptable, with 42 % of participants retained at 12 weeks. In addition, in a subset of participants with complete data, we found a significant increase in both citizenship scores and dimensions of wellness from baseline to week 12, with the greatest improvements in the occupational, intellectual, financial, and personal responsibility dimensions. As drug overdose rates among Black and Latinx people who use substances continue to increase, it is imperative that we address the inequities in the SDOH that contribute to this disparity gap so that we can develop interventions tailored to the specific needs of Black and Latinx people who use drugs. The Imani Breakthrough intervention shows promise as a community-driven approach that can address these disparities and promote health equity.

Abstract
The development of high-density multielectrode catheters has significantly advanced cardiac electrophysiology mapping. High-density grid catheters have enabled the creation of a novel technique for reconstructing electrogram (EGM) signals known as "omnipole," which is believed to be more reliable than other methods, especially in terms of orientation independence. This study aims to evaluate how distance affects the omnipolar reconstruction of EGMs by comparing different configurations. Using an animal set up of perfused isolated rabbit hearts, recordings were taken using an ad hoc high-density epicardial multielectrode catheter. Inter-electrode distances ranging from 1 to 4 mm were analysed for their effect on the quality of resulting EGMs. Two biomarkers were computed to evaluate the robustness of the reconstructions: the areas contained within the bipolar loops and the amplitudes of the omnipoles. We hypothesised that both bipolar and omnipolar electrograms would be more robust at shorter inter-electrode distances. The results showed that an increase in distance triggers an increase in loop areas and amplitudes, which supports the hypothesis. This finding provides a more reliable estimate of wavefront propagation for the cross-omnipolar reconstruction method. These results emphasise the importance of distance in cardiac electrophysiology mapping and provide valuable insights into the use of high-density multielectrode catheters for EGM reconstruction.Clinical Relevance- The results of this study have direct clinical relevance in the application of the described techniques to recording systems in the cardiac electrophysiology laboratory, enabling clinicians to obtain more precise characterisation of signals in the myocardium.

Abstract
BACKGROUND Large international differences exist in kidney transplantation (KT) rates. We aimed to investigate which factors may explain the total, deceased donor, and living donor KT rates over the last decade. METHODS KT experts from 39 European countries completed the Kidney Transplantation Rate Survey on measures and barriers and their potential effect on the KT rate in their country. In the analyses, countries were divided into low, middle, and high KT rate countries based on the KT rate at the start of study period in 2010. RESULTS Experts from low KT rate countries reported more frequently to have taken measures regarding staff, equipment and facilities to increase total KT rate compared with middle and high KT rate countries. For donor type specific KT, the largest international differences in measures taken were reported for deceased donor KT, with middle and high KT rate countries taking more measures, such as the use of expanded criteria donor kidneys, the presence of transplantation coordinators, and (inter)national exchange of donor kidneys. Once a measure was taken, experts' opinion on its success was similar across the low, middle and high KT rate countries. Experts from low KT rate countries more often reported potential barriers, such as patients' lack of knowledge and distrust in the health care system. CONCLUSIONS In particular in low KT rate countries, KT rate might be stimulated by optimizing staff, equipment, and facilities. In addition, all countries may benefit from deceased and living donor specific measures.

Abstract
Background Trauma-focused cognitive-behavioural treatments have been proven to be effective for reducing symptoms in female survivors of intimate partner violence (IPV), although they still present some difficulties (e.g. significant drop-out rates, low adherence). Based on existing evidence about the difficulty of accessing memories of positive experiences among these women, we considered integrating positive memory evocation in trauma-focused treatments. The present study aims to test the effect of adding a positive memory module to trauma-focused CBT for female survivors of IPV. Methods The study is a single-blind, randomized controlled trial (RCT) comparing two trauma-focused CBT (with and without a positive memory module) for female survivors of IPV and a wait-list condition (superiority trial), including pretreatment and posttreatment measures, and follow-ups at 3, 6 and 12 months. Assessors of treatment outcome will be blinded to the trial arm. We aim to recruit 135 participants who will be randomized to one of the experimental conditions. The primary outcome is PTSD symptom severity. Secondary outcome measures include IPV, attitudes towards IPV, posttraumatic cognitions, centrality of trauma, self-concept, positive and negative affect, depression, anxiety, emotional dysregulation or health-related quality of life, as well as satisfaction with treatment. Moreover, adherence to and satisfaction with treatment will be considered. Discussion This study first analyses the effect of including positive memory evocation into a trauma-focused treatment for female survivors of IPV. This strategy aims to improve the effect of the treatments and enhance the healing of the trauma by developing a more integrated and emotionally modulated autobiographical narrative that contributes to the recovery and well-being of the victims.

Abstract
Persons living with mental health challenges are at increased risk of stigma, social isolation, and social exclusion. Due to its emphasis on member participation and community, the clubhouse model of mental health may help address these issues. In this study, we examined experiences of social belonging and of various social determinants of mental health among members attending a psychosocial clubhouse. Twelve members of a large psychosocial clubhouse were interviewed regarding their experiences of community life and belonging. Phenomenological qualitative methods were utilized to examine the meaning and structure of these experiences. Members overwhelmingly experienced the clubhouse as a central site of belonging ("an oasis"), but members also recounted devastating portraits of life in the outside world ("a desert"). This world presented fundamental restrictions on their movement and speech and held deeply sedimented norms pertaining to who is considered valuable, productive, and even human, which they were reminded of through an endless tyranny of questions ("what do you do," "where do you live," etc.). Life in the clubhouse presented an alternative world for members to experience nourishment, dignity, reaffirmed personhood, and a sense of beauty. And yet, the desert outside remained. Implications of these findings for clubhouses, mental health practice, and sociopolitical and community engagement are discussed, including the need to address profound deprivations and power imbalances within the wider world, beyond the walls of humane spaces such as these.

Abstract
Febrile seizures (FS) are one of the most common types of convulsive disorder of early childhood and they can be classified into simple and prolonged depending on the duration. Nowadays, simple FS have a good prognosis but there is controversy about the outcome of prolonged FS. In a previous work using an animal model of prolonged FS, we showed that hiperthermia-induced seizures (HIS) evoked fine motor coordination impairment and gait disturbances in adolescent rats in a process in which seemed to be involved modulation of the cerebellar adenosinergic system. The aim of the present work was to verify whether the effect was maintained in adulthood. To this end, neonatal rats (PD 12) were exposed to HIS and after 48 days (PD 60) they were assayed on balance beam and footprint tests. Animals were sacrificed 53 days after HIS and adenosine A1 and A2A receptor signalling pathways were studied in cerebellar plasma membranes by using radioligand binding assays and by measuring the activities of 5´-nucleotidase and adenylyl cyclase. Results obtained revealed that adult rats exposed to HIS showed gait disturbances and motor impairments. Besides, animals exposed to hyperthermic insult showed an increase in adenosine A2A receptor functionality and 5´-nucleotidase activity. Surprisingly, the functionality of the adenosine A1 receptor resulted significantly changed causing stimulation instead of inhibition of adenylate cyclase activity. These results showed that the effect of prolonged FS at the early age also persist in adulthood suggesting on must pay attention to FS in children.

Abstract
BACKGROUND As the world battles COVID-19, there is a need to study the perceptions of people with intellectual and developmental disabilities (IDD) about the effects of the pandemic and associated lockdown on their lives. This work explores the perceptions of Spaniards with IDD during the lockdown with respect to four topics: access to information, emotional experiences, effects on living conditions and access to support. METHODS The topics were explored using a subset of 16 closed-ended questions from an online survey. In total, 582 participants with IDD completed the survey. The frequencies and percentages of responses to the questions were calculated, and chi-square tests performed to explore the relationship between participants' sociodemographic characteristics and responses. Given that people differed in the way in which they completed the survey, the relationship between participants' responses and completion method was also analysed. RESULTS Participants reported that the pandemic and subsequent lockdown have had a deleterious effect on their emotional well-being (around 60.0% of participants) and occupations (48.0% of students and 72.7% of workers). Although access to information and support was reportedly good overall, being under the age of 21 years and studying were associated with perceptions reflecting poorer access to information (V = .20 and V = .13, respectively) and well-being support (V = .15 and V = .13, respectively). Being supported by a third party to complete the survey was consistently related to perceptions of worse outcomes. CONCLUSIONS The study yielded data on the perceptions of people with IDD regarding the effects that COVID-19 and the subsequent lockdown have had on their lives. Suggestions on how to overcome the difficulties reported and future lines of research are discussed.

Abstract
One of the most frequent neurological disorders in children is febrile seizures (FS), a risk for epilepsy in adults. Glutamate is the main excitatory neurotransmitter in CNS acting through ionotropic and metabotropic receptors. Excess of glutamate in the extracellular space elicits excitotoxicity and has been associated with neurological disorders, such as epilepsy. The removal of extracellular glutamate by excitatory amino acid transporters (EATT) plays an important neuroprotective role. GLT-1 is the main EAAT present in the cortex brain. On the other hand, an increase in metabotropic glutamate receptors 5 (mGlu5R) levels or their overstimulation have been related to the appearance of seizure events in different animal models and in temporal lobe epilepsy in humans. In this work, the status of several components of the glutamatergic system has been analysed in the cortex brain from an FS rat model at short (48 h) and long (20 days) term after hyperthermia-induced seizures. At the short term, we detected increased GLT-1 levels, reduced glutamate concentration, and unchanged mGlu5R levels, without neuronal loss. However, at the long term, an increase in mGlu5R levels together with a decrease in both GLT-1 and glutamate levels were observed. These changes were associated with the appearance of an anxious phenotype. These results suggest a neuroprotective role of the glutamatergic components mGlu5R and GLT-1 at the short term. However, this neuroprotective effect seems to be lost at the long term, leading to an anxious phenotype and suggesting an increased vulnerability and propensity to epileptic events in adults.

Abstract
BACKGROUND Activation of the PI3K/AKT/mTOR pathway through loss of phosphatase and tensin homolog (PTEN) occurs in approximately 50% of patients with metastatic castration-resistant prostate cancer (mCRPC). Recent evidence suggests that combined inhibition of the androgen receptor (AR) and AKT may be beneficial in mCRPC with PTEN loss. PATIENTS AND METHODS mCRPC patients who previously failed abiraterone and/or enzalutamide, received escalating doses of AZD5363 (capivasertib) starting at 320 mg twice daily (b.i.d.) given 4 days on and 3 days off, in combination with enzalutamide 160 mg daily. The co-primary endpoints were safety/tolerability and determining the maximum tolerated dose and recommended phase II dose; pharmacokinetics, antitumour activity, and exploratory biomarker analysis were also evaluated. RESULTS Sixteen patients were enrolled, 15 received study treatment and 13 were assessable for dose-limiting toxicities (DLTs). Patients were treated at 320, 400, and 480 mg b.i.d. dose levels of capivasertib. The recommended phase II dose identified for capivasertib was 400 mg b.i.d. with 1/6 patients experiencing a DLT (maculopapular rash) at this level. The most common grade ≥3 adverse events were hyperglycemia (26.7%) and rash (20%). Concomitant administration of enzalutamide significantly decreased plasma exposure of capivasertib, though this did not appear to impact pharmacodynamics. Three patients met the criteria for response (defined as prostate-specific antigen decline ≥50%, circulating tumour cell conversion, and/or radiological response). Responses were seen in patients with PTEN loss or activating mutations in AKT, low or absent AR-V7 expression, as well as those with an increase in phosphorylated extracellular signal-regulated kinase (pERK) in post-exposure samples. CONCLUSIONS The combination of capivasertib and enzalutamide is tolerable and has antitumour activity, with all responding patients harbouring aberrations in the PI3K/AKT/mTOR pathway.

Abstract
IntroductionDespite the four factor model of PTSD proposed in the DSM-5 (APA, 2013) has received a better empirical support than three factor model of DSM-IV (APA, 1994), some alternative models proposed can provide a better representation of PTSD's latent structure.ObjectiveThe current study tested the fit of seven models, including the 3-factor DSM-IV model (APA, 1994), the 4-factor DSM-5 model (APA, 2000), the 4-factor dysphoria model (Simms, Watson & Doebbeling, 2002), the 5-factor dysphoric arousal model (Elhai et al., 2012), the 6-factor anhedonia model (Liu et al., 2014), the 6-factor externalizing behaviors model (Tsai et al., 2014) and the 7-factor hybrid model (Armour et al., 2015) that combines key features of the anhedonia and externalizing behaviors models.AimIt expected that the 7-factor hybrid model (Armour et al., 2015) would be the best fitting model.MethodsPTSD symptoms were assessed using the Global Assessment of Posttraumatic Stress Disorder (EGEP-5; Crespo, Gómez & Soberón, 2016) in a sample of 165 victims of different traumatic events. Confirmatory Factor Analysis (CFAs) were conducted on each of the seven models using Maximum Likelihood (ML) estimation method.ResultsAll the models tested (except for DSM-IV model) yielded an adequate fit to the data. However, 7-factor hybrid model (Armour et al., 2015) provided a better fit than other competing models.ConclusionsThe current findings suggest that the dimensional structure of DSM-5 PTSD symptoms may be best represented by the 7 factors proposed in the hybrid model instead of 4 factors of DSM-5.References not available.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Background The development of treatment response and surrogate biomarkers for advanced prostate cancer care is an unmet clinical need. Patients with baseline circulating tumour cell (BLCTCs) counts <5/7.5 mL represent a good prognosis subgroup but are non-evaluable for response assessment (decrease in CTCs). The aim of the study is to determine the value of any increase in CTCs (CTC progression) as an indicator of progression in prostate cancer patients with low pre-treatment CTCs (<5). Patients and methods We carried out a post hoc analysis of patients with BLCTCs < 5 treated in the COU-AA-301 (abiraterone or placebo + prednisone) and IMMC-38 (chemotherapy) trials. The association of CTC progression (increase in CTCs at 4, 8 or 12 weeks) with overall survival (OS) was evaluated in multi-variable Cox regression models. Performance of survival models with and without CTC progression was evaluated by calculating ROC curve area under the curves (AUCs) and weighted c-indices. Results Overall, 511 patients with CTCs < 5 (421 in COU-AA-301 and 90 in IMMC-38) were selected; 212 (41.7%) had CTC progression at 4, 8 or 12 weeks after treatment initiation. CTC progression was associated with significantly worse OS [27.1 versus 15.1 m; hazard ratio (HR) 3.4 (95% confidence interval [CI] 2.5-4.5; P < 0.001)], independent of baseline CTCs and established clinical variables. Adding CTC progression to the OS model significantly improved ROC AUC (0.77 versus 0.66; P < 0.001). Models including CTC progression had superior ROC AUC (0.77 versus 0.69; P < 0.001) and weighted c-index [0.750 versus 0.705; delta c-index: 0.045 (95% CI 0.019-0.071)] values than those including CTC conversion (increase to CTCs ≥ 5). In COU-AA-301, the impact of CTC progression was independent of treatment arm. Conclusions Increasing CTCs during the first 12 weeks of treatment are independently associated with worse OS from advanced prostate cancer in patients with baseline CTCs < 5 treated with abiraterone or chemotherapy and improve models with established prognostic variables. These findings must be prospectively validated.

Abstract
Background Deletion of the chromatin remodeler chromodomain helicase DNA-binding protein 1 (CHD1) is a common genomic alteration found in human prostate cancers (PCas). CHD1 loss represents a distinct PCa subtype characterized by SPOP mutation and higher genomic instability. However, the role of CHD1 in PCa development in vivo and its clinical utility remain unclear. Patients and methods To study the role of CHD1 in PCa development and its loss in clinical management, we generated a genetically engineered mouse model with prostate-specific deletion of murine Chd1 as well as isogenic CHD1 wild-type and homozygous deleted human benign and PCa lines. We also developed patient-derived organoid cultures and screened patients with metastatic PCa for CHD1 loss. Results We demonstrate that CHD1 loss sensitizes cells to DNA damage and causes a synthetic lethal response to DNA damaging therapy in vitro, in vivo, ex vivo, in patient-derived organoid cultures and in a patient with metastatic PCa. Mechanistically, CHD1 regulates 53BP1 stability and CHD1 loss leads to decreased error-free homologous recombination (HR) repair, which is compensated by increased error-prone non-homologous end joining (NHEJ) repair for DNA double-strand break (DSB) repair. Conclusions Our study provides the first in vivo and in patient evidence supporting the role of CHD1 in DSB repair and in response to DNA damaging therapy. We uncover mechanistic insights that CHD1 modulates the choice between HR and NHEJ DSB repair and suggest that CHD1 loss may contribute to the genomic instability seen in this subset of PCas.

Abstract
UNLABELLED Bone health is assessed by bone mineral density (BMD). Other techniques such as trabecular bone score and microindentation could improve the risk of fracture's estimation. Our chronic kidney disease (CKD) patients presented worse bone health (density, microarchitecture, mechanical properties) than controls. More than BMD should be done to evaluate patients at risk of fracture. INTRODUCTION BMD measured by dual-energy X-ray absorptiometry (DXA) is used to assess bone health in end-stage renal disease (ESRD) patients. Recently, trabecular bone score (TBS) and microindentation that can measure microarchitectural and mechanical properties of bone have demonstrated better correlation with fractures than DXA in different populations. We aimed to characterize bone health (BMD, TBS, and strength) and calcium/phosphate metabolism in a cohort of 53 ESRD patients undergoing kidney transplantation (KT) and 94 controls with normal renal function. METHODS Laboratory workout, lumbar spine/hip BMD measurements (using DXA), lumbar spine TBS, and bone strength were carried out. The latter was assessed with an impact microindentation device, standardized as percentage of a reference value, and expressed as bone material strength index (BMSi) units. Multivariable linear regression was used to study differences between cases and controls adjusted by age, gender, and body mass index. RESULTS Among cases, serum calcium was 9.6 ± 0.7 mg/dl, phosphorus 4.4 ± 1.2 mg/dl, and intact parathyroid hormone 214 pg/ml [102-390]. Fourteen patients (26.4%) had prevalent asymptomatic fractures in spinal X-ray. BMD was significantly lower among ESRD patients compared to controls: lumbar 0.966 ± 0.15 vs 0.982 ± 0.15 (adjusted p = 0.037), total hip 0.852 ± 0.15 vs 0.902 ± 0.13 (adjusted p < 0.001), and femoral neck 0.733 ± 0.15 vs 0.775 ± 0.12 (adjusted p < 0.001), as were TBS (1.20 [1.11-1.30] vs 1.31 [1.19-1.43] (adjusted p < 0.001)) and BMSi (79 [71.8-84.2] vs 82. [77.5-88.9] (adjusted p = 0.005)). CONCLUSIONS ESRD patients undergoing transplant surgery have damaged bone health parameters (density, microarchitecture, and mechanical properties) despite acceptably controlled hyperparathyroidism. Detecting these abnormalities may assist in identifying patients at high risk of post-transplantation fractures.

Abstract
Patients with end-stage renal disease have longer survival after kidney transplantation than they would by remaining on dialysis; however, outcome with kidneys from donors aged ≥75 years and the survival of recipients of these organs compared with their dialysis counterparts with the same probability of obtaining an organ is unknown. In a longitudinal mortality study, 2040 patients on dialysis were placed on a waiting list, and 389 of them received a first transplant from a deceased donor aged ≥75 years. The adjusted risk of death and survival were calculated by non-proportional hazards analysis with being transplanted as a time-dependent effect. Projected years of life since placement on the waiting list was almost twofold higher for transplanted patients. Nonproportional adjusted risk of death after transplantation was 0.44 (95% confidence interval [CI] 0.61-0.32; p < 0.001) in comparison with those that remained on dialysis. Stratifying by age, adjusted hazard ratios for death were 0.17 (95% CI 0.47-0.06; p = 0.001) for those aged <65 years, 0.56 (95% CI 0.92-0.34; p = 0.022) for those aged 65-69 years and 0.82 (95% CI 1.28-0.52; p = 0.389) for those aged ≥70 years. Although kidney transplantation from elderly deceased donors is associated with reduced graft survival, transplanted patients have lower mortality than those remaining on dialysis.

Abstract
Control of the microscopic structure of CNT nanocomposites allows modulation of the electromagnetic shielding in the gigahertz range. The porosity of CNT scaffolds has been controlled by two freezing protocols and a subsequent lyophilization step: fast freezing in liquid nitrogen and slow freezing at -20 °C. Mercury porosimetry shows that slowly frozen specimens present a more open pore size (100-150 μm) with a narrow distribution whereas specimens frozen rapidly show a smaller pore size and a heterogeneous distribution. 3D-scaffolds containing 3, 4, 6 and 7% CNT were infiltrated with epoxy and specimens with 2, 5 and 8 mm thicknesses were characterized in the GHz range. Samples with the highest pore size and porosity presented the lowest reflected power (about 30%) and the highest absorbed power (about 70%), which allows considering them as electromagnetic radiation absorbing materials.

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.
