Abstract
INTRODUCTION Negative symptoms are nuclear features of schizophrenia that may be present from the onset of the disease. In recent years, it has been described 2 subdomains of negative symptoms: experiential and expressive deficits. The aim of the study is to examine the relationship between negative symptoms and demographic and clinical variables in patients with first-episode psychosis. Also, to explore whether there are differences in the association among these variables and negative symptoms when divided into both subdomains. MATERIAL AND METHODS A cross-sectional study was performed in 160 patients (52 females and 108 males) with a diagnosis of a first episode psychosis. A questionnaire was administered to collect demographic and clinical variables. RESULTS A backward stepwise linear regressions analysis was performed in order to observe potential associations between demographic and clinical variables and the presence of negative symptoms. All three models are predicted by worse PSP score, a higher CDSS, a higher disorganized factor score and a lower excited factor score. A longer duration of untreated psychosis (DUP) is associated to a higher score in the experiential deficit subdomain only. CONCLUSIONS Our work highlights some clinical and phenomenological differences between experiential and expressive deficits. We think that taking into account both subdomains in future studies may lead to more accurate clinical assessment and interventions.

Abstract
BACKGROUND Schizophrenia patients often show obsessive-compulsive symptoms (OCS) and obsessive-compulsive disorder (OCD) and their presence has been associated with poorer prognosis. However, the impact of OCS/OCD on psychotic severity remains unclear. The aim of this study is twofold: 1) to investigate the effect of OCS/OCD on the severity of positive, negative, and global psychotic symptoms of schizophrenia patients and 2) to analyze the effect of patient and study-related covariates on moderating this relationship. METHODS A systematic review and meta-analysis (SRMA) of studies comparing the severity of psychotic symptoms among schizophrenia patients with and without OCS/OCD was performed. Standardized mean difference (SMD) was calculated for positive, negative, and global psychotic symptoms. The difference of SMD (Diff SMD) was calculated to analyze the effect of covariates on study outcomes using meta-regression. RESULTS Sixty-seven studies involving 7740 patients were included. Patients with schizophrenia and OCS/OCD showed a slightly higher severity of positive (SMD = 0.17, p value = 0.0089) and global psychotic symptoms (SMD = 0.24, p value = 0.0104) than patients without OCS/OCD but no differences in negative symptoms were found between groups (SMD = 0.11, p value = 0.0367). Only one covariate "proportion of patients without antipsychotics (AP)" was found to modify the effect on psychotic severity (Diff SMD = -0.008, p value = 0.002). CONCLUSIONS Comorbid OCS/OCD in schizophrenia has, at most, a minor impact on psychotic severity. Variability in this effect was considerable and was poorly explained by the covariates analyzed.

Abstract
Little is known about the pathophysiological mechanisms of relapse in first-episode schizophrenia, which limits the study of potential biomarkers. To explore relapse mechanisms and identify potential biomarkers for relapse prediction, we analyzed gene expression in peripheral blood in a cohort of first-episode schizophrenia patients with less than 5 years of evolution who had been evaluated over a 3-year follow-up period. A total of 91 participants of the 2EPs project formed the sample for baseline gene expression analysis. Of these, 67 provided biological samples at follow-up (36 after 3 years and 31 at relapse). Gene expression was assessed using the Clariom S Human Array. Weighted gene co-expression network analysis was applied to identify modules of co-expressed genes and to analyze their preservation after 3 years of follow-up or at relapse. Among the 25 modules identified, one module was semi-conserved at relapse (DarkTurquoise) and was enriched with risk genes for schizophrenia, showing a dysregulation of the TCF4 gene network in the module. Two modules were semi-conserved both at relapse and after 3 years of follow-up (DarkRed and DarkGrey) and were found to be biologically associated with protein modification and protein location processes. Higher expression of DarkRed genes was associated with higher risk of suffering a relapse and early appearance of relapse (p = 0.045). Our findings suggest that a dysregulation of the TCF4 network could be an important step in the biological process that leads to relapse and suggest that genes related to the ubiquitin proteosome system could be potential biomarkers of relapse.

Abstract
BACKGROUND Social cognition has been associated with functional outcome in patients with first episode psychosis (FEP). Social cognition has also been associated with neurocognition and cognitive reserve. Although cognitive reserve, neurocognitive functioning, social cognition, and functional outcome are related, the direction of their associations is not clear. Therefore, the main aim of this study was to analyze the influence of social cognition as a mediator between cognitive reserve and cognitive domains on functioning in FEP both at baseline and at 2 years. METHODS The sample of the study was composed of 282 FEP patients followed up for 2 years. To analyze whether social cognition mediates the influence of cognitive reserve and cognitive domains on functioning, a path analysis was performed. The statistical significance of any mediation effects was evaluated by bootstrap analysis. RESULTS At baseline, as neither cognitive reserve nor the cognitive domains studied were related to functioning, the conditions for mediation were not satisfied. Nevertheless, at 2 years of follow-up, social cognition acted as a mediator between cognitive reserve and functioning. Likewise, social cognition was a mediator between verbal memory and functional outcome. The results of the bootstrap analysis confirmed these significant mediations (95% bootstrapped CI (-10.215 to -0.337) and (-4.731 to -0.605) respectively). CONCLUSIONS Cognitive reserve and neurocognition are related to functioning, and social cognition mediates in this relationship.

Abstract
BACKGROUND Our aim is to examine differences in sexual functioning (SF) between patients with drug-naïve first episode psychosis (FEP) and healthy controls (HC). We will also examine correlations between prolactin levels, testosterone levels and psychotic symptomatology with SF from a gender perspective. METHODS Cross-sectional study. We included 68 FEP patients and 50 HC. A blood sample was extracted. We used the Positive and Negative Syndrome Scale to assess symptom severity, using the five factor structure according to Emsley. The Changes in Sexual Function Questionnaire (CSFQ) was administered. RESULTS We found significantly better SF in HC than in patients (in CSFQ total score (p = 0.032) and in CSFQ Desire (p = 0.032)). A significant correlation between prolactin or testosterone and SF was not observed. We found a negative significant correlation between the disorganised subscale of the EMSLEY and total CSFQ (p = 0.027; r = -0.329), CSFQ Desire (p = 0.028; r = -0.329) and CSFQ Arousal (p = 0.026; r = -0.332) in the patient sample. In a regression model, we found sex (p = 0.003) and disorganized symptoms (p = 0.034) as significant predictors. CONCLUSIONS We found evidence for better SF in HC than in FEP patients. We could not confirm an association between prolactin or testosterone and SF. Disorganized symptomatology could be a relevant factor in SF.

Abstract
AIMS Here, we present a clustering strategy to identify phenotypes of antipsychotic (AP) response by using longitudinal data from patients presenting first-episode psychosis (FEP). METHOD One hundred and ninety FEP with complete data were selected from the PEPs project. The efficacy was assessed using total PANSS, and adverse effects using total UKU, during one-year follow-up. We used the Klm3D method to cluster longitudinal data. RESULTS We identified four clusters: cluster A, drug not toxic and beneficial; cluster B, drug beneficial but toxic; cluster C, drug neither toxic nor beneficial; and cluster D, drug toxic and not beneficial. These groups significantly differ in baseline demographics, clinical, and neuropsychological characteristics (PAS, total PANSS, DUP, insight, pIQ, age of onset, cocaine use and family history of mental illness). CONCLUSIONS The results presented here allow the identification of phenotypes of AP response that differ in well-known simple and classic clinical variables opening the door to clinical prediction and application of personalized medicine.

Abstract
AbstractObjectiveVerbal working memory span is decreased in patients with schizophrenia, and this might contribute to impairment in higher cognitive functions as well as to the formation of certain clinical symptoms. Processing speed has been identified as a crucial factor in cognitive efficiency in this population. We tested the hypothesis that decreased processing speed underlies the verbal working memory deficit in patients and mediates the associations between working memory span and clinical symptoms.MethodForty-nine schizophrenia inpatients recruited from units for chronic and acute patients, and forty-five healthy participants, were involved in the study. Verbal working memory span was assessed by means of the letter-number span. The Digit Copy test was used to assess motor speed, and the Digit Symbol Substitution Test to assess cognitive speed.ResultsThe working memory span was significantly impaired in patients (F(1,90) = 4.6, P < 0.05). However, the group difference was eliminated when either the motor or the cognitive speed measure was controlled (F(1,89) = 0.03, P = 0.86, and F(1,89) = 0.03, P = 0.88). In the patient group, working memory span was significantly correlated with negative symptoms (r = –0.52, P < 0.0001) and thought disorganisation (r = –0.34, P < 0.025) scores. Regression analyses showed that the association with negative symptoms was no longer significant when the motor speed measure was controlled (β = –0.12, P = 0.20), while the association with thought disorganisation was no longer significant when the cognitive speed measure was controlled (β = –0.10, P = 0.26).ConclusionsDecrement in motor and cognitive speed plays a significant role in both the verbal working memory impairment observed in patients and the associations between verbal working memory impairment and clinical symptoms.

Abstract
Facial emotion recognition refers to a person's interpretation of facial features of another to identify a particular emotional state. It is essential in human evolution and encompasses distinct neural networks. Facial emotion recognition is altered in most neurodegenerative diseases, but literature just focus on single neurological pathologies or limited comparison with psychiatric pathologies. It is unknown if a common pattern of affection through pathologies exists or if facial emotion recognition changes according to the underlying pathology. This review discusses its development in healthy population, synthesizes facial emotion recognition studies regarding most common neurological diseases, as well as most relevant findings in neuroimaging and current treatments. Facial emotion recognition, especially negative emotions, is altered in all described neurodegenerative diseases and could constitutes an early marker of cognitive deterioration.

Abstract
Recent studies have found hyperprolactinemia in first episode psychotic patients that had not previously received antipsychotic treatment (drug-naïve). Our goal was to learn whether there were differences in baseline prolactin concentrations between drug-naïve psychotic patients and healthy controls, as well as to study possible gender differences in the prolactin elevation. A cross-sectional study was conducted that included 61 drug-naïve psychosis patients and 45 healthy controls (aged between 14-55 years old). A blood sample was extracted between 8 and 10 a.m. Prolactin levels and TSH were determined. The Perceived Stress Scale (PSS) was conducted across the sample. This study showed significantly higher levels of prolactin in drug-naïve patients compared to healthy controls. These results were maintained after controlling prolactin levels for sex, age, THC consumption, baseline TSH, and PSS. A significant correlation between prolactin and PSS was not observed. Significant differences in prolactin levels between men and women were not observed. These results are clinically important because if elevated baseline prolactin levels are detected in these patients, it will be necessary to initiate neuroleptics that do not increase this hormone. There was no evidence that stress was related to an increase in prolactin at the onset of psychosis.

Abstract
BACKGROUND Both the nature and number of a wide range of prodromal symptoms have been related to the severity and type of psychopathology in the psychotic phase. However, at present there is an incomplete picture focused mainly on the positive pre-psychotic dimension. AIM To characterize the prodromal phase retrospectively, examining the number and nature of prodromal symptoms as well as their relationship with psychopathology at the onset of first-episode psychosis. METHODS Retrospective study of 79 patients experiencing a first-episode psychosis of less than 1 year from the onset of full-blown psychosis. All patients were evaluated with a comprehensive battery of instruments including socio-demographic and clinical questionnaire, IRAOS interview, PANSS, stressful life events scale (PERI) and WAIS/WISC (vocabulary subtest). Bivariate associations and multiple regression analysis were performed. RESULTS Regression models revealed that several prodromal dimensions of IRAOS (delusions, affect, language, behaviour and non-hallucinatory disturbances of perception) predicted the onset of psychosis, with positive (22.4% of the variance) and disorganized (25.6% of the variance) dimensions being the most widely explained. CONCLUSION In addition to attenuated positive symptoms, other symptoms such as affective, behavioural and language disturbances should also be considered in the definitions criteria of at-high-risk people.

Abstract
Two effective biocontrol products (named as BA3 and BA4) based on Bacillus amyloliquefaciens CPA-8 have been reported as a potential alternative to chemical applications against brown rot caused by Monilinia spp. on stone fruit. To have practical use, this study aimed to describe the best packaging strategies (bags or flasks, atmosphere, and temperature of storage) to not only guarantee efficacy but also stability and ease of application of the products to be handled through the normal channels of distribution and storage. In terms of the viability neither the BA3 nor the BA4 product has been compromised after twelve months of storage. However, storage at 4 °C affected the stability and visual aspect of both CPA-8 formulations, mainly associated not only to the increase of RH but also aw. Moreover, it should be pointed out that flasks did not conserve refrigerated BA3 samples in a suitable way, since RH and aw increased noticeably making their visual properties unsightly after 10 months of cold storage. At that time, the BA4 products were better preserved at 4 °C when packaged in flasks. Finally, this study also demonstrated that the most suitable packaging conditions for long-term storability (stored at 22 °C) did not show any negative effect in the biocontrol efficacy of CPA-8 in nectarines artificially infected with M. fructicola and provide suitable product delivery and field application. In conclusion, these results contribute to the final stage of development of these two CPA-8 products, practically ready for registration, thus contributing to the environmental-friendly management of postharvest diseases in stone fruit.

Abstract
Disinfection of surface facilities during postharvest handling operation is an important practice to avoid secondary fruit infections at stone fruit packinghouses. The aim of this work was to evaluate the effect of six environmental friendly disinfectants against Monilinia fructicola, Penicillium expansum, Rhizopus spp., and Alternaria spp. on plastic and wood surfaces. Hydrogen peroxide, peracetic acid, sodium hypochlorite, Mico-E-pro®, Proallium FRD-N®, and DMC Clean-CNS® were used as the disinfectants. Untreated and surfaces treated with water were used as controls. Plastic and wood surfaces were sampled with Rodac plates at 2 and 24 h after treatments and the number of colonies were counted. In general, all disinfectants reduce the number of viable conidia from all studied surfaces. Hydrogen peroxide used in a concentration of 150 mg L-1 was the less effective disinfectant in all studied pathogens. The commercial product Mico-E-pro® composed of oregano, onion, and orange extract at a dose of 10 mg L-1 was the most effective disinfectant. Rhizopus spp. was the pathogen more resistant to the disinfectants followed by P. expansum, M. fructicola, and Alternaria spp. Water decreased the number of conidia adhered to the surface. In addition, the untreated control showed substantial conidia reduction after 24 h of artificial inoculation.

Abstract
IntroductionThere is a wide range of studies focusing on the use of cannabis in first episode psychosis (PEP). Literature using child and adolescent samples is scarce.Objectives and aimsTo determine the prevalence and clinical differences between cannabis users and non-cannabis users of early onset first episode psychosis (EOP), and adult onset first episode psychosis (AOP).MethodOne hundred and forty patients were recruited in adult (AOP subsample, n = 69) and child and adolescent (EOP subsample, n = 71) mental health services. The Positive and Negative Syndrome Scale was used for psychotic symptoms and the Calgary Scale for affective symptoms. The Chi2 test analysed clinical differences between users and nonusers within subsamples, and in the total sample a Pearson correlation was used for the relationship between age at cannabis use and PEP.ResultsThe prevalence of lifetime use of cannabis and the average age at first use were 48% and 13.82 years (± 1.15) in the EOP subsample, and 58% and 17.78 years (± 3.93) in the AOP subsample. Within EOP, cannabis users were older (P = .001), had fewer negative symptoms (P = .045) and less depressive symptoms (P = .005). Within AOP, cannabis users were younger (P = .018) and had greater severity of positive symptoms (P = .021). Age at first cannabis use and age at PEP were positively correlated.ConclusionsCannabis use is prevalent in adult and early onset psychosis. Cannabis users differ clinically from non-users, and the earlier the use of cannabis, the earlier the onset of psychosis.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Brown rot on peaches and nectarines caused by Monilinia spp. results in significant economic losses in Europe. Experiments were conducted to study the effects of temperature (0-33 °C) on the temporal dynamics of decay and mycelium development and the subsequent sporulation on peaches and nectarine fruit infected by M. laxa and M. fructicola. The rates of decay and mycelium development increased with temperature from 0 °C to 25 °C for both Monilinia species. At 0 °C, decay was faster for M. laxa (0.20 cm2 days-1) than for M. fructicola (0.07 cm2 days-1); indeed, M. laxa was able to develop mycelia and sporodochia, but M. fructicola was not. At 4 and 20 °C, there were no differences in decay and mycelia development between the two Monilinia species. When temperature increased from 25 to 33 °C, the rates of fungal decay and mycelium development decreased. At 30 and 33 °C, M. fructicola decayed faster (0.94 and 1.2 cm2 days-1, respectively) than M. laxa (0.78 and 0.74 cm2 days-1, respectively) and could develop mycelia and produce sporodochia, whereas M. laxa failed at 33 °C. These results indicated that M. fructicola is better adapted to high temperatures, whereas M. laxa is better adapted to low temperatures. These results can be used to predict the relative importance of the two species during the season at a given site and to improve management strategies for brown rot in areas where both species are present.

Abstract
The effect of time (up to 24h) and temperature (40 to 55°C) has been evaluated on in vitro growth of Penicillium digitatum and Penicillium italicum on potato dextrose agar plates or on ‘Valencia’ oranges ( Citrus sinensis), previously inoculated with those pathogens. The effect of treatment on the fruit quality parameters has also been evaluated. In vitro, at 40 and 45°C, an exposure of 24h was required to inhibit subsequent mycelial growth of both pathogens during incubation for 1 week at 25°C. However, at 50 and 55°C, only 18 or 9h (6h for P. digitatum), respectively, were needed to achieve the same effect on both pathogens. Inoculated fruit was exposed for 18h at 40°C then stored for 5 days at 5°C plus 7 days at 20°C, and the experiment was repeated at three locations and over two fruit seasons. This curing regime controlled both pathogens effectively. Concerning quality changes, after cold storage (5°C), treated fruits showed a significant reduction in acid content and a slight delay on skin yellowing, on softening, and on weight losses, compared to the control fruits. These results suggest that the curing treatment could be a non-chemical alternative to the postharvest fungicides now used to control citrus green and blue moulds.

Abstract
IntroductionCannabis consumption is known to be increased in both schizophrenic and first psychotic episode patients. Contrary to what has been reported in studies with healthy people, all published studies so far have reported no impairments or even beneficial effects on neurocognition associated with cannabis consumption in schizophrenia and first psychotic episode patients. However, these studies did not address the effects of very high cannabis consumption.ObjectiveOur aim in this study was to assess the effects on neurocognition of regular and heavy cannabis consumption in first psychotic episode patients.MethodsA total of 74 patients were included in the study and assigned to 3 different groups according to their mean cannabis consumption during the last year (non-users, regular users, and heavy users). Participants were administered verbal memory, attention, processing speed, working memory, vocabulary, arithmetic and spatial orientation tasks.ResultsOur results showed the heavy cannabis group of first psychotic episode patients to be significantly impaired in all the verbal memory measures with respect to the non-users group. There were no significant differences between regular users and non-users. Moreover, regular cannabis consumption was associated with an improvement in some attention and processing speed measures.ConclusionsOur data showed heavy cannabis consumption to impair verbal memory in first psychotic episode patients and suggest a dose-related effect of cannabis consumption, since regular consumption did not impair verbal memory and may be beneficial for other tasks.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Fruits and vegetables can become contaminated by foodborne pathogens such as Escherichia coli O157:H7, Salmonella and Listeria monocytogenes, and it has been demonstrated that current industrial sanitizing treatments do not eliminate the pathogens when present. Chemical control is widely used, but biological control appears to be a better solution, mainly using the native microbiota present on fresh produce. The first objective of this study was to isolate native microbiota from whole and fresh-cut produce and to determine whether these bacteria were antagonistic toward foodborne pathogens. A total of 112 putative antagonist isolates were screened for their ability to inhibit the growth of Salmonella enterica on lettuce disks. Five different genera reduced S. enterica growth more than 1-log unit at 20°C at the end of 3 days. When tested against L. monocytogenes 230/3, only Pseudomonas sp. strain M309 (M309) was able to reduce pathogen counts by more than 1-log unit. Therefore, M309 strain was selected to be tested on lettuce disks at 10°C against S. enterica, E. coli O157:H7 and L. monocytogenes. M309 strain was only able to reduce S. enterica and E. coli O157:H7 populations. The second objective was to test different biopreservative methods including M309 strain, Pseudomonas graminis CPA-7 (CPA-7), bacteriophages (Listex P100 and Salmonelex) and nisin at conditions simulating commercial applications against Salmonella and L. monocytogenes on fresh-cut lettuce. The addition of the biopreservative agents did not result in a significant reduction of Salmonella population. However, CPA-7 strain together with nisin reduced L. monocytogenes numbers after 6 days of storage at 10°C. The cocktail of Salmonella and L. monocytogenes was not markedly inactivated by their respective bacteriophage solutions. This study highlighted the potential of biocontrol, but the combination with other technologies may be required to improve their application on fresh-cut lettuce.

Abstract
BACKGROUND Earlier age at onset of psychosis (AOP) has been associated with poor social adjustment and clinical outcome. Genetic and environmental factors such as obstetric complications, parental history of psychosis, advanced paternal age at time of birth, low birth weight and gestational age, and use of drugs have been described as bringing AOP forward. This study aims to evaluate the relationship between AOP and these factors in a sample of first episode of psychosis (FEP) patients. METHODS Clinical and sociodemographic data, age at FEP, age of parents at birth, parental history of psychosis, drug-use habits of the mother during pregnancy and of the patient before psychotic onset, and Lewis and Murray obstetric complication scale were obtained from 90 patients with FEP. Statistical analysis was performed by means of Pearson correlations, Chi-square tests, Student T-test analyses and a linear regression model using SPSS version 22. RESULTS Pre-eclampsia, need for incubator at birth, use of forceps, parental history of psychosis, and low birth weight were associated with an earlier AOP. Use of forceps and birth weight are the variables which best predict AOP in FEP. Stimulant drugs, which were mostly used together with cannabis and cocaine, were the only substances associated with an earlier AOP. CONCLUSIONS Our findings are consistent with previous study results and underline the role of the prenatal period in the development of psychosis and the importance of careful monitoring of pregnancy and delivery, especially in cases with familial history.

Abstract
AIMS As reliability of preharvest applications of biological control agents (BCAs) to control fruit pathogens is highly dependent on the survival of the selected organism, this study aimed to describe the population dynamics of the yeast-BCA Candida sake (Saito & Ota) CPA-1 on grape berries under the effect of abiotic factors such as temperature, relative humidity, sunlight and rainfall. METHODS AND RESULTS Candida sake (5 × 10(7) CFU ml(-1)), combined with different concentrations of the food additive Fungicover(®), was applied on grape berry clusters. Treated clusters were then exposed to abiotic factors in field or laboratory conditions, recovering populations to describe C. sake population dynamics. The addition of Fungicover significantly increased C. sake multiplication under optimal growth conditions and improved survival under fluctuating abiotic factors. After field applications, significant differences in populations on grape bunches exposed or covered by fine foliage were detected. Simulated rainfall washed off C. sake populations by 0·6-0·9 log units after 20 mm of rain volume. Allowing populations to establish for 24 h or more, prior to a rain event, persistence on grape berries significantly increased and the effect of rain intensity was not observable. CONCLUSIONS Candida sake demonstrated high survival ability under unfavourable environmental conditions and persistence under intense rain. The study evidenced the importance of the first period just after application for C. sake survival on grape tissues and also the protective effect of the additive Fungicover. SIGNIFICANCE AND IMPACT OF THE STUDY This research provides new information on the survival of C. sake under field conditions and its practical implications for recommending timing of spray with this antagonist. Our results could be useful for other yeast antagonists applied before harvest. This work, for the first time, defines population dynamics of a yeast BCA using simulated rainfall.

Abstract
Penicillium digitatum and Penicillium expansum are responsible for green and blue molds in citrus and pome fruits, respectively, which result in major monetary losses worldwide. In order to study their infection process in fruits, we successfully introduced a green fluorescent protein (GFP) encoding gene into wild type P. digitatum and P. expansum isolates, using Agrobacterium tumefaciens-mediated transformation (ATMT), with hygromycin B resistance as the selectable marker. To our knowledge, this is the first report describing the transformation of these two important postharvest pathogens with GFP and the use of transformed strains to study compatible and non-host pathogen interactions. Transformation did not affect the pathogenicity or the ecophysiology of either species compared to their respective wild type strains. The GFP-tagged strains were used for in situ analysis of compatible and non-host pathogen interactions on oranges and apples. Knowledge of the infection process of apples and oranges by these pathogens will facilitate the design of novel strategies to control these postharvest diseases and the use of the GFP-tagged strains will help to determine the response of P. digitatum and P. expansum on/in plant surface and tissues to different postharvest treatments.

Abstract
Escherichia coli O157:H7 outbreaks associated with produce consumption have brought attention to contaminated compost manure, and polluted irrigation water as potential sources of pathogens for the contamination of these crops. The aim of this study was to determine the potential transfer of E. coli O157:H7 from soil fertilized with contaminated compost or irrigated with contaminated water to edible parts of lettuce together with its persistence in soil under field conditions in two different seasons (fall and spring). Moreover, its survival on lettuce sprinkled with contaminated irrigation water was evaluated, as well as the prevalence of aerobic mesophilic, Enterobacteriaceae and Pseudomonadaceae in control lettuce samples. Four treatments, contaminated compost, surface and sprinkle irrigation with contaminated water and uninoculated pots, were used in this work. Contaminated compost was applied to soil in the pots before lettuce was transplanted and contaminated irrigation water was applied twice and three times on the plants after the seedlings were transplanted, for sprinkle and surface irrigation, respectively. E. coli O157:H7 survived in soil samples for 9 weeks at levels, 4.50 log cfu gdw(-1) (dw, dry weight) in fall and 1.50 log cfu gdw(-1) in spring. The pathogen survives better in fall, indicating an important influence of environmental factors. E. coli O157:H7 population in lettuce leaves after sprinkle irrigation was very high (between 10(3) and 10(6) cfu g(-1)), but decreased to undetectable levels at field conditions. There was also transfer of E. coli O157:H7 from soil contaminated with compost or irrigated with contaminated water to lettuce leaves, mainly to the outer ones. The mean counts for aerobic mesophilic, Enterobacteriaceae and Pseudomonadaceae populations were also influenced by environmental conditions; higher levels were observed under fall conditions than in spring conditions. Contamination of lettuce plants in the field can occur through both contaminated composted manure and irrigation water and persist for several months.

Abstract
AIMS To prepare commercially acceptable formulations of Bacillus subtilis CPA-8 by spray-drying with long storage life and retained efficacy to control peach and nectarine brown rot caused by Monilinia spp. METHODS AND RESULTS CPA-8 24-h- and 72-h-old cultures were spray dried using 10% skimmed milk, 10% skimmed milk plus 10% MgSO(4) , 10% MgSO(4) and 20% MgSO(4) as carriers/protectants. All carriers/protectants gave good percentages of powder recovery (28-38%) and moisture content (7-13%). CPA-8 survival varied considerably among spray-dried 24-h- and 72-h-old cultures. Seventy-two hours culture spray dried formulations showed the highest survival (28-32%) with final concentration products of 1·6-3·3 × 10(9) CFU g(-1) , while viability of 24-h-old formulations was lower than 1%. Spray-dried 72-h-old formulations were selected to subsequent evaluation. Rehydration of cells with water provided a good recovery of CPA-8 dried cells, similar to other complex rehydration media tested. Spray-dried formulations stored at 4 ± 1 and 20 ± 1°C showed good shelf life during 6 months, and viability was maintained or slightly decreased by 0·2-0·3-log. CPA-8 formulations after 4- and 6 months storage were effective in controlling brown rot caused by Monilinia spp. on nectarines and peaches resulting in a 90-100% reduction in disease incidence. CONCLUSIONS Stable and effective formulations of biocontrol agent B. subtilis CPA-8 could be obtained by spray-drying. SIGNIFICANCE AND IMPACT OF THE STUDY New shelf-stable and effective formulations of a biocontrol agent have been obtained by spray-drying to control brown rot on peach.

Abstract
Social functioning (SF) is the ultimate target aimed in treatment plans in schizophrenia, thus it is critical to know what are the factors that determine SF. Gender is a well-established variable influencing SF, yet it is not known how social variables and symptoms interact in schizophrenia patients. Furthermore, it remains unclear whether the interaction between social variables and symptoms is different in men compared to women. Our aim is to test whether social variables are better predictors of SF in community-dwelled individuals with schizophrenia, and whether men and women differ in how symptoms and social variables interact to impact SF. Community-dwelling individuals with schizophrenia (N = 231) were randomly selected from a register. Participants were assessed with symptom measures (PANSS), performance-based social scale (LSP), objective social and demographic variables. Stratification by gender and stepwise multivariate regression analyses by gender were used to find the best-fitting models that predict SF in both gender. Men had poorer SF than women in spite of showing similar symptom scores. On stepwise regression analyses, gender was the main variable explaining SF, with a significant contribution by disorganized and excitatory symptoms. Age of onset made a less marked, yet significant, contribution to explain SF. When the sample was stratified by gender, disorganized symptoms and 'Income' variable entered the model and accounted for a 30.8% of the SF variance in women. On the other hand, positive and disorganized symptoms entered the model and accounted for a 36.1% of the SF variance in men. Community-dwelling men and women with schizophrenia differ in the constellation of variables associated with SF. Symptom scores still account for most of the variance in SF in both genders.

Abstract
Many foodborne outbreaks of some pathogens such as Escherichia coli O157:H7, Salmonella or Listeria have been associated with the consumption of contaminated vegetables. Contaminated manure and polluted irrigation water are probable vehicles for the pathogens. The aim of this study was to determine the potential transfer of Listeria innocua from soil fertilized with contaminated compost or irrigated with contaminated water to the edible parts of lettuce grown on these soils together with its survival in lettuce and in soil under field conditions during two different seasons. Moreover, its survival on lettuce sprinkled with contaminated irrigation water was evaluated. L. innocua survived in soil samples for 9 weeks at high concentrations, 10(5) cfu gdw(-1) in fall and 10(3) cfu gdw(-1) in spring. Pathogen survived better in fall, indicating an important influence of temperature and humidity. L. innocua population in lettuce leaves was very high on lettuce leaves after sprinkling, but decreased to undetectable levels at field conditions. There was also transfer of L. innocua from soil contaminated with compost or irrigated with contaminated water to lettuce leaves, mainly to the outer ones. Survival profiles of L. innocua on lettuce and soil samples contaminated either by application of contaminated compost or surface irrigation water was similar. Our results indicated that contaminated compost and contaminated irrigation water can play an important role in the presence of foodborne pathogens on vegetables.

Abstract
Previously there was no available information on the levels of indicator bacteria and the prevalence of pathogens in fresh lettuce grown in organic and conventional farms in Spain. A total of 72 lettuce samples (18 farms for 4 repetitions each) for each type of the agriculture were examined in order to assess the bacteriological quality of the lettuces, in particular the prevalence of selected pathogens. The lettuce samples were analyzed for the presence of aerobic mesophilic, psychrotrophic microorganisms, yeasts and moulds, Enterobacteriaceae, mesophilic lactic acid bacteria, Pseudomonas spp. and presumptive Escherichia coli, Salmonella spp. and Listeria monocytogenes. The mean aerobic mesophilic counts (AM) were 6.35 +/- 0.69 log(10) cfu g(-1) and 5.67 +/- 0.80 log(10) cfu g(-1) from organic and conventional lettuce, respectively. The mean counts of psychrotrophic microorganisms were 5.82 +/- 1.01 log(10) cfu g(-1) and 5.41 +/- 0.92 log(10) cfu g(-1) from organic and conventional lettuce, respectively. Yeasts and moulds (YM) mean counts were 4.74 +/- 0.83 log(10) cfu g(-1) and 4.21 +/- 0.96 log(10) cfu g(-1) from organic and conventional lettuce, respectively. Lactic acid bacteria (LAB) were present in low numbers and the mean counts were 2.41 +/- 1.10 log(10) cfu g(-1) and 1.99 +/- 0.91 log(10) cfu g(-1) from organic and conventional lettuce, respectively. Pseudomonas spp. mean counts were 5.49 +/- 1.37 log(10) cfu g(-1) and 4.98 +/- 1.26 log(10) cfu g(-1) in organic and conventional lettuce, respectively. The mean counts for Enterobacteriaceae were 5.16 +/- 1.01 log(10) cfu g(-1) and 3.80 +/- 1.53 log(10) cfu g(-1) in organic and conventional lettuce, respectively. E. coli was detected in 22.2% (16 samples) of organic lettuce and in 12.5% (9 samples) of conventional lettuce. None of the lettuce samples was positive for E. coli O157:H7, L. monocytogenes and Salmonella spp. From the samples analyzed by principal component analysis (PCA) a pattern with two different groups (conventional and organic) can be observed, being the highest difference between both kinds of samples the Enterobacteriaceae count.

Abstract
Immediately following the identification of Monilinia fructicola in a Spanish peach orchard in the Ebro Valley in 2006, this orchard and two other orchards in the same valley were intensively sampled for potential tree and ground sources of primary Monilinia inoculum before and during three growing seasons between 2006 and 2008. Overwintered Monilinia spp. produced inoculum from only mycelium, and no apothecia were found in any of the three orchards over the three growing seasons. Mummies on trees were the main source of primary inoculum. More than 90% of Monilinia isolates on all fruit mummies were M. laxa. Positive relationships were found between (i) the number of mummified fruit and the incidence of postharvest brown rot (P = 0.05, r = 0.75, n = 8), and (ii) the number of mummified fruit and nonabscised aborted fruit in the trees and the number of conidia on the fruit surface (P = 0.04, r = 0.71; P = 0.01, r = 0.94, respectively, n = 8) and the incidence of latent infection (P = 0.03, r = 0.75; P = 0.001, r = 0.99; respectively, n = 8). In addition, the numbers of mummified fruit and pruned branches on the orchard floor were correlated with the number of airborne conidia in the orchard. Based on the results of these surveys, the control of brown rot in stone fruit orchards is discussed.

Abstract
Fresh produce can be a vehicle for the transmission of pathogens capable of causing human illnesses and some of them can grow on fresh-cut vegetables. The survival and growth of Escherichia coli O157:H7, Salmonella spp. and Listeria monocytogenes inoculated onto shredded lettuce was determined under modified atmosphere packaging conditions, at various storage temperatures. We also monitored changes in pH and gas atmospheres within the packages and the growth of psychrotrophic and mesophilic microorganisms. After pathogen inoculation, shredded lettuce was packaged in films of different permeability and stored at 5 and 25 degrees C. After 10 days at 5 degrees C populations of E. coli O157:H7 and Salmonella decreased approximately 1.00 log unit while L. monocytogenes increased about 1.00 log unit, in all package films. Moreover, the pathogens level increased between 2.44 and 4.19 log units after 3 days at 25 degrees C. Psychrotrophic and mesophilic bacteria had similar growth at both temperatures with higher populations in air than in the other atmospheres. The composition of the storage atmosphere within the packaging of lettuce had no significant effect on the survival and growth of the pathogens used in this study at refrigeration temperatures. The results obtained can be considered as a warning indicator, which reinforces the necessity for corrective measures to avoid contamination of vegetables.

Abstract
AIMS To study the population dynamics of Epicoccum nigrum on peaches and nectarines and to enhance its colonization on fruit surfaces to improve its biocontrol efficacy against brown rot. METHODS AND RESULTS Twelve surveys were performed to study E. nigrum populations and their effect on the number of the pathogenic Monilinia spp. conidia in peach orchards in Spain and Italy between 2002 and 2005. Fresh conidia and five different formulations of E. nigrum conidia were applied three to six times to peach and nectarine trees from full flowering to harvest. The size of the E. nigrum populations was determined from the number of colony-forming units and conidial numbers per flower or fruit. Treatment with all conidial formulations increased the size of the indigenous conidial population on peach surfaces. CONCLUSIONS Formulations of E. nigrum having high viability are most effective against conidia of the pathogen when applied at pit hardening and during the month immediately before fruit harvest. SIGNIFICANCE AND IMPACT OF THE STUDY Application of an E. nigrum conidial formulation decreased the number of conidia of Monilinia spp. on fruit surfaces during the growing season to the same extent as fungicides.

Abstract
Monilinia fructicola causes brown rot of stone fruit in India, Japan, the Republic of Korea, Oceania, and North and South America and is in the A2 list of quarantine organisms for Europe. M. fructicola was found in peach orchards for the first time in Europe in 2001 in France (4) and later in the Czech Republic (2). M. fructicola was not detected among 428 isolates of Monilinia spp. collected from Spanish peach orchards from 1998 to 2005. In March of 2006, M. fructicola was detected to be overwintering in three mummified peach fruit (cv. Autumn Free) trees in an orchard located in Sudanell (Lleida, Spain). Morphological and molecular identification of isolates were performed according to protocols previously described (1,3). The characteristics of these isolates were: i) colonies were entire and showing concentric rings of spores when grown on potato dextrose agar (PDA); ii) sporogenous tissues were gray to buff; iii) single and nearly straight germ tubes were at least 220 μm long before branching; and iv) growth rates on PDA under long-wave UV/darkness were as much as 20 × 10 mm2. Isolates were further identified by a PCR test using primers developed with sequence-characterized amplification region markers obtained by random amplified polymorphic DNA for M. fructicola: IColaS (GAGACGCACACAGAGTCAG) and IColaAS (GAGACGCACATAGCATTGG) (3). The expected PCR product of 386 bp was produced only in M. fructicola isolates. Koch's postulates were fulfilled with the three isolates by inoculating five healthy fruit with a conidial suspension of each isolate (104 conidia ml-1). Symptoms similar to those observed in the field were small brown spots, which rapidly showed brown rot. Noninoculated control fruit did not show symptoms. The fungus was reisolated on PDA from inoculated fruit after 4 days of incubation at 22°C, 80 to 100% relative humidity, and 16 h under fluorescent lighting, 100 μE·m-2·s-1. To our knowledge, this is the first report of M. fructicola in peach orchards in Spain. References: (1) A. De Cal and P. Melgarejo. Plant Dis. 83:62, 1999. (2) J. Duchoslavová et al.

Abstract
AIMS The objective of this work was to determine the role of different compatible solutes in adaptation of Pantoea agglomerans CPA-2 at different stages of growth to solute (0.98, 0.97, 0.96 aw), heat (35 and 40 degrees C) and acidic (pH 4.0, 5.0, 6.0) stress. METHODS AND RESULTS Solute stress was imposed by using NaCl, glucose or glycerol, and pH was imposed with malic and citric acids. The accumulation of glycine-betaine, ectoine and amino acids in bacterial cells was quantified using high performance liquid chromathography (HPLC). There was a significant (P<0.05) accumulation of glycine-betaine (NaCl modified, 100-150 micromol g(-1) dry weight of cells) and ectoine (glucose modified media, >340 micromol g(-1) dry weight of cells) in the cells over a 48 h incubation period when compared with controls (<10 micromol g(-1) dry weight of cells). Chromatographic profile of amino acids was different with respect to control when NaCl or glucose was used as osmolyte. CONCLUSIONS Pantoea agglomerans CPA-2 cells synthesised significant amounts of glycine-betaine and ectoine in response to imposed solute stress. However, these compounds and tested amino acids were not involved in cellular adaptation to either heat or pH stress. SIGNIFICANCE AND IMPACT OF THE STUDY This type of information can be effectively applied to improve ecophysiological quality of cells of bacterial biocontrol agents for better survival and biocontrol efficacy in the phyllosphere of plants.

Abstract
INTRODUCTION Between 17% and 30% of the world population suffers from a mental disorder in a given year and only a small proportion of them established contact with health services. This information is not available concerning the Spanish population. This study aims to describe the health services utilization related with mental disorders in Spain, as well as to identify factors related with such utilization. METHODS The ESEMeD-Spain is an epidemiological study carried out on a representative sample of the Spanish adult general population, with a sample size of 5,473 individuals. We used the Composite International Diagnostic Interview (version 3.0) to collect information concerning mental disorders symptoms, health services utilization related with mental health, and administered treatments, with a 12 months time frame. RESULTS 57% of those suffering from a mood disorder, 30.3 % of those suffering from an anxiety disorder and 71.7% of those suffering from both contacted health services in the year they suffered the disorder. Psychiatrists were the most frequently consulted professionals when a 12 month mental disorder was present, with the exception of anxiety disorders or comorbid mood-anxiety disorders. A 30.8% of those with any 12 month mental disorder who did consult were not prescribed with any treatment. Variables significantly related to 12 month health services utilization were age, gender, marital status, and mental disorders. CONCLUSIONS A large proportion of individuals suffering from mental disorders do not use health services or, if indeed use them, do not receive any type of treatment.

Abstract
The aim of this work was to optimize acid stress conditions for induction of acid tolerance response (ATR) in the biocontrol agent Pantoea agglomerans and study the effect of ATR induced on the ability to survive under acidic conditions. Initially, Pantoea agglomerans was grown in mild acidic conditions (pH 6.0, 5.5, 5.0 and 4.0) in order to induce ATR. The highest ATR was induced at initial pH of 5 using malic or citric acid. A first in vitro experiment was carried out. Thus, basal liquid medium at different pHs (3.0, 3.5, 4.0 and non-acidified) were then inoculated with acid-adapted and non-adapted inocula of P. agglomerans and survivals were examined during incubation at 25 or 4 degrees C. It was found that acid adaptation enhanced the survivals of Pantoea agglomerans CPA-2 cells at pH levels at which the cells were unable to grow (<3.5 and 4.0, at 25 and 4 degrees C, respectively). In contrast, in pH levels at which the cells were able to grow (pH 4.0 at 25 degrees C and non-acidified medium at 25 and 4 degrees C) no-differences were found between adapted and non-adapted cells. In in vivo tests, adapted and non-adapted cells were inoculated in wounds on mandarins and pome fruits. No differences were found between adapted and non-adapted cells and biocontrol efficacy was maintained. The present study demonstrated that exposure of Pantoea agglomerans to mild acidic conditions could induce acid resistance in this biocontrol agent.

Abstract
The effectiveness of a formulated product of the yeast Candida sake CPA-1 for controlling postharvest diseases on pome fruits was demonstrated in laboratory, semicommercial, and commercial trials carried out in the major pome fruit producing region of the European Union. First, one wettable powder and seven liquid formulations were tested in laboratory trials that involved two varieties of apples and two varieties of pears. In all cases, an efficacy similar to that of fresh cells was demonstrated in the control of artificial Penicillium expansum infection. After these trials, the formulated product chosen for semicommercial and commercial trials was LF1, a liquid formulation that is particularly suitable for commercial applications. In semicommercial trials, LF1 showed a performance similar to fresh cells in most trials, and the population dynamics of both fresh and formulated cells were quite stable throughout the storage period. This indicates the high viability of C. sake CPA-1 in this formulation and the absence of adverse effects during the formulation of the product, which may significantly affect both its ability to grow on fruit and its antagonistic activity. We evaluated the control of natural infection after applying the formulated product in a commercial drencher in different packinghouses. A significant reduction in the incidence of diseases was observed with a recommended dose of around 10(7) CFU/ml when natural infections were greater than 1%. In general, large quantities of yeast were observed on the surface of unwounded fruits of different pome fruit cultivars. Moreover, populations of this biocontrol agent increased rapidly on fruit surfaces and remained quite stable for a long time under commercial storage conditions. Commercial practices used in packinghouses were therefore successfully applied for this formulated product.

Abstract
AIMS To study the improvement of tolerance to low water activity (aw) and desiccation during spray drying in Pantoea agglomerans cells subjected to mild osmotic stress during growth. METHODS AND RESULTS The micro-organism was cultured in an unmodified liquid (control) or in aw-modified media, and viability of these cells was evaluated on unstressed (0.995) and 0.96 aw stressed solid media, in order to check total viability and aw stress tolerance respectively. Significant improvements in viability on unmodified medium were observed with cells grown for 24 h in NaCl 0.98 aw, glycerol 0.98 aw and 0.97 aw and for 48 h in NaCl 0.98 aw and 0.97 aw modified media. Both yield improvements and water stress tolerance were achieved with low aw media. Cells grown for 24 h in NaCl 0.98 aw or for 48 h in NaCl 0.98 aw, 0.97 aw and 0.96 aw, glucose 0.97 aw and glycerol 0.97 aw showed improved aw stress tolerance in comparison with control cells. The best results were obtained with NaCl treatments (0.98 aw and 0.97 aw) which also exhibited better survival rates than control cells during spray-drying process and maintained their efficacy against postharvest fungal pathogens in apples and oranges. CONCLUSIONS NaCl treatments are very appropriate for improving P. agglomerans low aw tolerance obtaining high production levels and maintaining biocontrol efficacy. SIGNIFICANCE AND IMPACT OF THE STUDY Improving stress tolerance of biocontrol agents could be an efficient way to obtain consistency and maintain efficacy of biological control under practical conditions.

Abstract
AIMS The effect of modifying the water activity (a(w)) of Pantoea agglomerans growth medium with the ionic solute NaCl on water stress resistance, heat-shock survival and intracellular accumulation of the compatible solutes glycine-betaine and ectoine were determined. METHODS AND RESULTS The bacterium was cultured in an unmodified liquid medium or that modified with NaCl to 0.98 and 0.97 a(w), and viability of cells evaluated on a 0.96 a(w)-modified solid media to check water stress tolerance. Cells grown under ionic stress had better water stress tolerance than control cells. These cells also had cross-protection to heat stress (30 min, 45 degrees C). The modified cells accumulated substantial amounts of the compatible solutes glycine-betaine and ectoine in contrast to the control cells, which contained little or none of these two compounds. CONCLUSIONS Improvement in osmotic and thermal tolerance of cells of the biocontrol agent P. agglomerans by modifying growth media with the ionic solute NaCl was achieved. The compatible solutes glycine-betaine and ectoine play a critical role in environmental stress tolerance improvement. SIGNIFICANCE AND IMPACT OF THE STUDY This approach provides a method for improving the physiological quality of inocula and could have implications for formulation and shelf-life of biocontrol agents.

Abstract
OBJECTIVE To analyse the association between symptom dimensions in schizophrenia and number and type of met and unmet needs. METHOD A sample of 231 outpatients randomly selected from a register that included all patients treated in 5 mental health care centres (MHCC) was evaluated. Assessment instruments included the Camberwell Assessment of Needs (CAN) questionnaire and the PANSS. RESULTS Number of needs are related to overall severity of psychopathology. Patients with more symptoms have more total needs (p < 0.001) and unmet needs (p < 0.001). A multiple lineal regression model showed that the disorganized and excited dimensions of the PANSS are the most important components for explaining the variance of number of needs. Type of needs is related to subtypes of schizophrenia, specially with disorganized and excited symptoms. CONCLUSION Psychosocial needs are related to schizophrenia subtypes. Patients with more needs are those with more disorganized and excitatory symptoms.
