Abstract
BACKGROUND AND PURPOSE The presence of apolipoprotein E4 (APOE*E4) is the strongest currently known genetic risk factor for Alzheimer disease and is associated with brain gray matter loss, notably in areas involved in Alzheimer disease pathology. Our objective was to assess the effect of APOE*E4 on brain structures in healthy elderly controls who subsequently developed subtle cognitive decline. MATERIALS AND METHODS This prospective study included 382 community-dwelling elderly controls. At baseline, participants underwent MR imaging at 3T, extensive neuropsychological testing, and genotyping. After neuropsychological follow-up at 18 months, participants were classified into cognitively stable controls and cognitively deteriorating controls. Data analysis included whole-brain voxel-based morphometry and ROI analysis of GM. RESULTS APOE*E4-related GM loss at baseline was found only in the cognitively deteriorating controls in the posterior cingulate cortex. There was no APOE*E4-related effect in the hippocampus, mesial temporal lobe, or brain areas not involved in Alzheimer disease pathology. Controls in the cognitively deteriorating group had slightly lower GM concentration in the hippocampus at baseline. Higher GM densities in the hippocampus, middle temporal lobe, and amygdala were associated with a decreased risk for cognitively deteriorating group status at follow-up. CONCLUSIONS APOE*E4-related GM loss in the posterior cingulate cortex (an area involved in Alzheimer disease pathology) was found only in those elderly controls who subsequently developed subtle cognitive decline but not in cognitively stable controls. This finding might explain the partially conflicting results of previous studies that typically did not include detailed neuropsychological assessment and follow-up. Most important, APOE*E4 status had no impact on GM density in areas affected early by neurofibrillary tangle formation such as the hippocampus and mesial temporal lobe.

Abstract
Ligand-dependent corepressor (LCoR) is a transcriptional repressor of ligand-activated estrogen receptors (ERs) and other transcription factors that acts both by recruiting histone deacetylases and C-terminal binding proteins. Here, we first studied LCOR gene expression in breast cancer cell lines and tissues. We detected two mRNAs variants, LCoR and LCoR2 (which encodes a truncated LCoR protein). Their expression was highly correlated and localized in discrete nuclear foci. LCoR and LCoR2 strongly repressed transcription, inhibited estrogen-induced target gene expression and decreased breast cancer cell proliferation. By mutagenesis analysis, we showed that the helix-turn-helix domain of LCoR is required for these effects. Using in vitro interaction, coimmunoprecipitation, proximity ligation assay and confocal microscopy experiments, we found that receptor-interacting protein of 140 kDa (RIP140) is a LCoR and LCoR2 partner and that this interaction requires the HTH domain of LCoR and RIP140 N- and C-terminal regions. By increasing or silencing LCoR and RIP140 expression in human breast cancer cells, we then showed that RIP140 is necessary for LCoR inhibition of gene expression and cell proliferation. Moreover, LCoR and RIP140 mRNA levels were strongly correlated in breast cancer cell lines and biopsies. In addition, RIP140 positively regulated LCoR expression in human breast cancer cells and in transgenic mouse models. Finally, their expression correlated with overall survival of patients with breast cancer. Taken together, our results provide new insights into the mechanism of action of LCoR and RIP140 and highlight their strong interplay for the control of gene expression and cell proliferation in breast cancer cells.

Abstract
Introduction.The In-patient units are very closed and highly controlled healthcare resource and then patients have to join the community rapidly, and in sometimes feeling unprotected and with their needs non covered. We created a transition unit with a program of psychotherapeutic intervention, to offer an adequate transition between the acute episode and the incorporation to the community.Objective.We describe the characteristics of the psychotherapeutic group, the aims and the results of the interventions.Methods.Psychotherapeutic transition unit was created to offer intensive attention and control demand that is not possible to control in the community. The objects are to prevent re-admissions and relapse because of abandonment of treatment in patient with personality disorder and suicide attempts, and first episode, affective or psychotic. Patients are selected from the in-patients unit with inclusion criteria, and start going from the unit before discharge. The intervention is once per week, with a duration between 60–90 minutes. There is not a number of sessions, and we have approximately 10 patients per sessions.Results.Since the beginning of the psychotherapeutic interventions, re-admissions have been decreased in patients with diagnosis of personality disorder (most histrionic and borderline disorder) with multiple admissions because of suicide attempt, some had been discharged. In another group of patient we have prevented relapses.Conclusions.Psychotherapeutic interventions will be effective in patients with high risk of re-admissions and relapses. It is early to have solid conclusions, but the preliminary results encourage the continuation of the program.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
OBJECTIVES Provide evidence based guidelines for tracheostomy in critically ill adult patients and identify areas needing further research. METHODS A task force composed of representatives of 10 member countries of the Pan-American and Iberic Federation of Societies of Critical and Intensive Therapy Medicine and of the Latin American Critical Care Trial Investigators Network developed recommendations based on the Grading of Recommendations Assessment, Development and Evaluation system. RESULTS The group identified 23 relevant questions among 87 issues that were initially identified. In the initial search, 333 relevant publications were identified of which 226 publications were chosen. The task force generated a total of 19 recommendations: 10 positive (1B=3, 2C=3, 2D=4) and 9 negative (1B=8, 2C=1). A recommendation was not possible in six questions. CONCLUSION Percutaneous techniques are associated with a lower risk of infections compared to surgical tracheostomy. Early tracheostomy only seems to reduce the duration of ventilator use but not the incidence of pneumonia, the length of stay, or the long-term mortality rate. The evidence does not support the use of routine bronchoscopy guidance or laryngeal masks during the procedure. Finally, proper prior training is as important or even a more significant factor in reducing complications than the technique used.

Abstract
Drug-resistant tuberculosis (DR-TB) is a growing public health problem, and for the first time in decades, new drugs for the treatment of this disease have been developed. These new drugs have prompted strengthened efforts in DR-TB clinical trials research, and there are now multiple ongoing and planned DR-TB clinical trials. To facilitate comparability and maximise policy impact, a common set of core research definitions is needed, and this paper presents a core set of efficacy and safety definitions as well as other important considerations in DR-TB clinical trials work. To elaborate these definitions, a search of clinical trials registries, published manuscripts and conference proceedings was undertaken to identify groups conducting trials of new regimens for the treatment of DR-TB. Individuals from these groups developed the core set of definitions presented here. Further work is needed to validate and assess the utility of these definitions but they represent an important first step to ensure there is comparability in clinical trials on multidrug-resistant TB.

Abstract
BACKGROUND AND PURPOSE The presence of cerebral microbleeds has been associated with dementia and cognitive decline, although studies report conflicting results. Our aim was to determine the potential role of the presence and location of cerebral microbleeds in early stages of cognitive decline. MATERIALS AND METHODS Baseline 3T MR imaging examinations including SWI sequences of 328 cognitively intact community-dwelling controls and 72 subjects with mild cognitive impairment were analyzed with respect to the presence and distribution of cerebral microbleeds. A neuropsychological follow-up of controls was performed at 18 months post inclusion and identified cases with subtle cognitive deficits were referred to as controls with a deteriorating condition. Group differences in radiologic parameters were studied by using nonparametric tests, 1-way analysis of variance, and Spearman correlation coefficients. RESULTS Cerebral microbleed prevalence was similar in subjects with mild cognitive impairment and controls with stable and cognitively deteriorating conditions (25%-31.9%). In all diagnostic groups, lobar cerebral microbleeds were more common. They occurred in 20.1% of all cases compared with 6.5% of cases with deep cerebral microbleeds. None of the investigated variables (age, sex, microbleed number, location and depth, baseline Mini-Mental State Examination score, and the Fazekas score) were significantly associated with cognitive deterioration with the exception of education of >12 years showing a slight but significant protective effect (OR, 0.44; 95% CI, 0.22-0.92; P = .028). The Mini-Mental State Examination and the Buschke total score were correlated with neither the total number nor lobar-versus-deep location of cerebral microbleeds. CONCLUSIONS Cerebral microbleed presence, location, and severity are not related to the early stages of cognitive decline in advanced age.

Abstract
STUDY QUESTION How do semen parameters of HIV-infected men under antiretroviral treatment compare with WHO parameters of normal semen, and what factors are associated with any differences? SUMMARY ANSWER Semen quality in most HIV-infected patients under antiretroviral treatment exceeds WHO limits, but the number falling below them is higher than would be expected in a healthy population. Exposure to efavirenz has a significant association with dysmotility. WHAT IS KNOWN ALREADY Dysmotility is the most frequently described sperm alteration related to HIV infection, and it has recently been linked to treatment with non-nucleoside reverse transcriptase inhibitors, particularly to efavirenz. STUDY DESIGN, SIZE, DURATION Prospective cohort study. Between March 2002 and December 2013, 139 HIV-infected men undergoing antiretroviral therapy were enrolled. PARTICIPANTS/MATERIALS, SETTING, METHODS Participants were male members of serodiscordant couples who attended a clinic for sexually transmitted infections (STIs) in Madrid and requested reproductive counselling. Sociodemographic, behavioural and clinical data were collected. CD4+ lymphocyte count, HIV viral load, serology/viral load of hepatitis B and C viruses, syphilis serology and other STIs diagnosis were performed. Semen parameters were assessed through standard sperm analysis and were compared with WHO 2010 reference values. Factors associated with impaired semen parameters were evaluated by bivariate and multivariate analysis. MAIN RESULTS AND THE ROLE OF CHANCE The median values of all assessed semen parameters were within a normal range, but in up to 19% of HIV-positive males, at least one parameter of semen quality was below the normal range. A significant association between treatment with efavirenz and the presence of dysmotility was detected in the multivariate analysis. LIMITATIONS, REASONS FOR CAUTION Our results cannot demonstrate a causal relationship between exposure to efavirenz and impaired motility. We do not have a real comparison group as the WHO cohort is international and may not reflect local variations in semen characteristics. Subjects who requested reproductive counselling might not be representative of HIV-positive men in general. WIDER IMPLICATIONS OF THE FINDINGS Since efavirenz is still widely used in current therapeutic regimens may be affecting fertility in seropositive men who desire procreation. STUDY FUNDING/COMPETING INTERESTS No external funding was used for this study. The authors have no conflict of interest to declare.

Abstract
Background HIV-1-controllers maintain HIV-1 viremia at low levels (normally <2000 HIV-RNA copies/mL) without antiretroviral treatment. However, some HIV-1-controllers have evidence of immunologic progression with marked CD4+T-cell decline. We investigated host genetic factors associated with protection against CD4+T-cell loss in HIV-1-controllers. Methods We analysed the association of interferon lambda 4 (IFNL4)-related polymorphisms and HLA-B haplotypes within Long Term Non-Progressor HIV-1-controllers ((LTNP-C), defined by maintaining CD4+T-cells counts >500 cells/mm3 for more than 7 years after HIV-1 diagnosis) versus non-LTNP-C, who developed CD4+T-cells counts <500 cells/mm3 Both a Spanish study cohort (n=140) and an international validation cohort (n=914) were examined. Additionally, in a subgroup of individuals HIV-1-specific T-cell responses and soluble cytokines were analysed RESULTS: HLA-B*57 was independently associated with the LTNP-C phenotype (OR=3.056 (1.029-9.069) p=0.044 and OR=1.924 (1.252-2.957) p=0.003) while IFNL4 genotypes represented independent factors for becoming non-LTNP-C (TT/TT, ss469415590, OR=0.401 (0.171-0.942) p=0.036 or A/A, rs12980275, OR=0.637 (0.434-0.934) p=0.021) in the Spanish and validation cohort, respectively, after adjusting for sex, age at HIV-1 diagnosis, IFNL4-related polymorphisms and different HLA-B haplotypes. LTNP-C showed lower plasma IP-10 (p=0.019) and higher IFN-γ (p=0.02) levels than the HIV-1-controllers with diminished CD4+T-cell numbers. Moreover, LTNP-C exhibited higher quantities of IL2+CD57- and IFN-γ+CD57- HIV-1-specific CD8+T-cells (p=0.002 and 0.041, respectively) than non-LTNP-C. Conclusions We have defined genetic markers able to segregate stable HIV-1-controllers from those who experience CD4+T-cell decline. These findings allow for identification of HIV-1-controllers at risk for immunologic progression, and provide avenues for personalized therapeutic interventions and precision medicine for optimizing clinical care of these individuals.

Abstract
Clostridium difficile is recognised worldwide as the main cause of infectious bacterial antibiotic-associated diarrhoea in hospitals and other healthcare settings. The aim of this study was to first survey C. difficile prevalence during the summer of 2014 at the Central University Hospital of Asturias (Spain). By typing the isolates obtained, it was then possible to compare the ribotype distribution at the Spanish hospital with results from the St Luc University Hospital in Belgium over the same period. The prevalence of positive cases reported in Spain and Belgium was 12.3% and 9.3% respectively. The main PCR-ribotypes previously described in Europe were found in both hospitals, including 078, 014, 012, 020 and 002. In the Spanish hospital, most of the C. difficile-positive samples were referred from oncology, acute care and general medicine services. In the Belgian hospital the majority of positive samples were referred from the paediatric service. However, a high percentage of isolates from this service were non-toxigenic. This study finds that the presence and detection of C. difficile in paediatric and oncology services requires further investigation.

Abstract
Background The traditional model of community pharmacy has changed, with patients, caregivers and consumers having access to many cognitive services other than the traditional dispensing and supply of medicines. In December 2009, a population-based colorectal cancer screening program started in Barcelona, introducing the community pharmacist and the professional expertise of the pharmacist into the organisational model. Aim To evaluate the program implementation process in the pharmacies, identify barriers and facilitators, and know the opinion of the professionals involved in the colorectal cancer screening program in Catalonia (Spain). Methods Cross-sectional study of the pharmacies that participated in the first round of the program during the first and second trimester of 2010 in Barcelona. A validated questionnaire was used to analyse several functional aspects in the implementation process. Qualitative aspects about the opinion of the pharmacist were studied. A descriptive and bivariate analysis was performed. Results All the pharmacies involved in the program (n = 74) participated in the study. The majority of the sample population was composed of women (70.3%), mean age 44.9 years, and most of them (74%) had attended a specific training session. Pharmacists considered their participation in the program to be an added value to their professional role and a way to increase consumer’s confidence on this kind of services. The average time to provide the service was estimated to be less than 10 minutes per consumer. Only three (4.1%) pharmacists considered that the program involved a lot of extra work in the daily activities of the pharmacy. The level of satisfaction of the pharmacists was very high. Conclusions Community pharmacies can be a successful alternative and great resource to implement a population cancer screening program. This functional model can improve the accessibility and participation rates on target population. The level of motivation of the community pharmacist, the specific training program and the perception to give a better care for their patients can be an enabler.

Abstract
Recognised as the leading cause of nosocomial antibiotic-associated diarrhoea, the incidence of Clostridium difficile infection (CDI) remains high despite efforts to improve prevention and reduce the spread of the bacterium in healthcare settings. In the last decade, many studies have focused on the epidemiology and rapid diagnosis of CDI. In addition, different typing methods have been developed for epidemiological studies. This review explores the history of C. difficile and the current scope of the infection. The variety of available laboratory tests for CDI diagnosis and strain typing methods are also examined.

Abstract
Zoonoses are infections or diseases that can be transmitted between animals and humans through direct contact, close proximity or the environment. Clostridium difficile is ubiquitous in the environment, and the bacterium is able to colonise the intestinal tract of both animals and humans. Since domestic and food animals frequently test positive for toxigenic C. difficile, even without showing any signs of disease, it seems plausible that C. difficile could be zoonotic. Therefore, animals could play an essential role as carriers of the bacterium. In addition, the presence of the spores in different meats, fish, fruits and vegetables suggests a risk of foodborne transmission. This review summarises the current available data on C. difficile in animals and foods, from when the bacterium was first described up to the present.

Abstract
Clostridium difficile remains the leading cause of healthcare-associated diarrhoea and outbreaks continue to occur worldwide. Aside from nosocomial C. difficile infection, the bacterium is also increasingly important as a community pathogen. Furthermore, asymptomatic carriage of C. difficile in neonates, adults and animals is also well recognised. The investigation of the gut's microbial communities, in both healthy subjects and patients suffering C. difficile infection (CDI), provides findings and information relevant for developing new successful approaches for its treatment, such as faecal microbiota transplantation, or for the prophylaxis of the infection by modification of the gut microbiota using functional foods and beverages. The analysis of all available data shows new insights into the role of intestinal microbiota in health and disease.

Abstract
Multilocus sequence typing (MLST), multilocus variable-number tandem-repeat analysis (MLVA) and antimicrobial susceptibility were performed on 37 animal and human C. difficile isolates belonging to 15 different PCR-ribotypes in order to investigate the relatedness of human and animal isolates and to identify possible transmission routes. MLVA identified a total of 21 different types while MLST only distinguished 12 types. Identical C. difficile strains were detected in the same animal species for PCR-ribotypes 014, 078, UCL 16U and UCL 36, irrespective of their origin or the isolation date. Non clonal strains were found among different hosts; however, a high genetic association between pig and cattle isolates belonging to PCR-ribotype 078 was revealed. MLVA also showed genetic differences that clearly distinguished human from animal strains. For a given PCR-ribotype, human and animal strains presented a similar susceptibility to the antimicrobials tested. All strains were susceptible to vancomycin, metronidazole, chloramphenicol and rifampicin, while PCR-ribotypes 078, UCL 5a, UCL 36 and UCL 103 were associated with erythromycin resistance. The data suggest a wide dissemination of clones at hospitals and breeding-farms or a contamination at the slaughterhouse, but less probability of interspecies transmission. However, further highly discriminatory genotyping methods are necessary to elucidate interspecies and zoonotic transmission of C. difficile.

Abstract
The simultaneous detection of cyanotoxins is an important issue in order to prevent intoxications. In the present paper an Ultra Performance liquid Chromatography tandem mass spectrometry UPLC-MS/MS method was developed in order to simultaneously identify and quantify cylindrospermopsin (CYN), several microcystins (MC-LR, MC-RR, MC-YR) and some anatoxin-a (ATX-a) analogues. By using this new method all these toxins can be quickly separate. In addition the amino acid phenylalanine (Phe) can also be separate and therefore misidentifications with ATX-a can be avoided. By using this new method the presence of these toxins was studied in samples collected in several German localizations within the sampling program of the European Project μAqua (Universal microarrays for the evaluation of fresh-water quality based on detection of pathogens and their toxins). In these conditions, several ATX-a analogues, Phe, MC-LR and MC-RR were reported in samples collected.
