Abstract
AIMS Pneumonitis is a common and potentially deadly complication of combined chemoradiation and immune checkpoint inhibition (CRT-ICI) in patients with locally advanced non-small cell lung cancer (LA-NSCLC). In this study we sought to identify the risk factors for pneumonitis with CRT-ICI therapy in LA-NSCLC cases and determine its impact on survival. MATERIALS AND METHODS We conducted a retrospective chart review of 140 patients with LA-NSCLC who underwent curative-intent CRT-ICI with durvalumab between 2018 and 2021. Pneumonitis was diagnosed by a multidisciplinary team of clinical experts. We used multivariable cause-specific hazard models to identify risk factors associated with grade ≥2 pneumonitis. We constructed multivariable Cox proportional hazard models to investigate the impact of pneumonitis on all-cause mortality. RESULTS The median age of the cohort was 67 years; most patients were current or former smokers (86%). The cumulative incidence of grade ≥2 pneumonitis was 23%. Among survivors, 25/28 patients had persistent parenchymal scarring. In multivariable analyses, the mean lung dose (hazard ratio 1.14 per Gy, 95% confidence interval 1.03-1.25) and interstitial lung disease (hazard ratio 3.8, 95% confidence interval 1.3-11.0) increased the risk for pneumonitis. In adjusted models, grade ≥2 pneumonitis (hazard ratio 2.5, 95% confidence interval 1.0-6.2, P = 0.049) and high-grade (≥3) pneumonitis (hazard ratio 8.3, 95% confidence interval 3.0-23.0, P < 0.001) were associated with higher all-cause mortality. CONCLUSIONS Risk factors for pneumonitis in LA-NSCLC patients undergoing CRT-ICI include the mean radiation dose to the lung and pre-treatment interstitial lung disease. Although most cases are not fatal, pneumonitis in this setting is associated with markedly increased mortality.

Abstract
AIMS The importance of autoantibodies (AABs) against adrenergic/muscarinic receptors in heart failure (HF) is not well-understood. We investigated the prevalence and clinical/prognostic associations of four AABs recognizing the M2-muscarinic receptor or the β1-, β2-, or β3-adrenergic receptor in a large and well-characterized cohort of patients with HF. METHODS AND RESULTS Serum samples from 2256 patients with HF from the BIOSTAT-CHF cohort and 299 healthy controls were analysed using newly established chemiluminescence immunoassays. The primary outcome was a composite of all-cause mortality and HF rehospitalization at 2-year follow-up, and each outcome was also separately investigated. Collectively, 382 (16.9%) patients and 37 (12.4%) controls were seropositive for ≥1 AAB (P = 0.045). Seropositivity occurred more frequently only for anti-M2 AABs (P = 0.025). Amongst patients with HF, seropositivity was associated with the presence of comorbidities (renal disease, chronic obstructive pulmonary disease, stroke, and atrial fibrillation) and with medication use. Only anti-β1 AAB seropositivity was associated with the primary outcome [hazard ratio (95% confidence interval): 1.37 (1.04-1.81), P = 0.024] and HF rehospitalization [1.57 (1.13-2.19), P = 0.010] in univariable analyses but remained associated only with HF rehospitalization after multivariable adjustment for the BIOSTAT-CHF risk model [1.47 (1.05-2.07), P = 0.030]. Principal component analyses showed considerable overlap in B-lymphocyte activity between seropositive and seronegative patients, based on 31 circulating biomarkers related to B-lymphocyte function. CONCLUSIONS AAB seropositivity was not strongly associated with adverse outcomes in HF and was mostly related to the presence of comorbidities and medication use. Only anti-β1 AABs were independently associated with HF rehospitalization. The exact clinical value of AABs remains to be elucidated.

Abstract
Abstract
Background
Myocardial deposition of amyloid proteins results in restrictive cardiomyopathy. Left ventricular global longitudinal strain (GLS) has emerged as a sensitive measure for detecting subclinical cardiac dysfunction over traditional echocardiographic parameters. However, multiple studies have provided differing conclusions regarding prognostic utility of impaired GLS in patients with systemic amyloidosis.
Purpose
We conducted a systematic review and meta-analysis to evaluate whether impaired GLS was associated with increased mortality or major adverse cardiovascular events (MACE) in patients with systemic amyloidosis.
Methods
We performed a literature search of Embase, Medline and Web of Science databases to identify studies that reported the association of GLS with clinical outcomes in patients with systemic amyloidosis (light chain or TTR amyloidosis). Outcomes of interest included all-cause mortality and MACE, defined as a composite of death or heart transplant or heart failure hospitalization. Unadjusted and adjusted hazard ratio (uHR and aHR respectively) were pooled using a random effects model. Heterogeneity among the studies was assessed using the Higgins I2 value.
Results
Out of 2139 initial citations, 28 observational studies with a total of 2713 patients were included in the analysis. The mean age ranged between 58–78 years and 62% of the patients were male. Most patients had cardiac amyloidosis (83%) and light-chain amyloidosis accounted for 69% of cases. Mean follow-up ranged between 1 and 5 years. GLS was significantly higher (less negative) (mean difference (MD) −3.69 [−5.94, −1.44], I2=87, p<0.01) in non-survivors compared with survivors. Similarly, patients who experienced MACE had a significantly higher mean GLS (MD −3.22, [−5.21, −1.22,], I2=82, p<0.01]. The risk of both mortality and MACE increased significantly for every −1% increase in GLS. In unadjusted models, a GLS above the defined threshold value was associated with a significantly higher risk of mortality (uHR: 1.66 [1.22, 5.21], I2=85.2, p<0.01) and MACE (uHR: 2.24 [1.28, 3.92], I2=39, p<0.01). In multivariable models an increase in GLS by −1% was an independent predictor of mortality (aHR: 1.09 [1.01,1.16], I2=53, p=0.02) and MACE (aHR: 1.24 [1.14,1.36], I2=0, p<0.01).
Conclusion
In patient with amyloidosis, the baseline left ventricular GLS may help identify patients with a higher risk of mortality and MACE.

Abstract
Abstract
Background
Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) use for circulatory support in shock is limited by increased left ventricular afterload. Impella and intra-aortic balloon pump (IABP) can be used in conjunction with VA-ECMO to help unload the left ventricle. Data comparing the two strategies are limited.
Purpose
We performed a systematic review and meta-analysis of published data to compare outcomes of patients with shock supported by VA-ECMO in conjunction with Impella versus IABP.
Methods
We conducted a search of Medline, Embase, and Cochrane databases to identify studies comparing the use of Impella versus IABP in patients on VA-ECMO. The primary outcome of interest was all-cause mortality (in-hospital or 30-day). Secondary outcomes included transition to destination therapy with left ventricular assist device (LVAD) or transplant, stroke, need for continuous renal replacement therapy (CRRT), bleeding, and hemolysis. Risk ratios (RR) with 95% confidence interval and the heterogeneity statistic I2 were reported for each outcome.
Results
Six observational studies with a total of 629 patients were included in the analysis. Of these, 205 (33%) and 424 (67%) patients were supported by Impella and IABP respectively, in addition to VA-ECMO. All six studies reported the primary outcome. No difference was observed in all-cause mortality between VA-ECMO with Impella and VA-ECMO with IABP (RR 1.02 [0.74–1.40], I2=74%). Similar rates were observed for transition to LVAD or transplant (RR 0.75 [0.45–1.27], I2=0%), stroke (RR 1.50 [0.80–2.83], I2=0%), and need for CRRT (RR 1.04 [0.82–1.32], I2=0%). However, use of VA-ECMO with Impella was associated with a higher risk of bleeding (RR 1.91 [1.28–2.86], I2=68%) and hemolysis (RR 4.61 [1.24–17.17], I2=66%) as compared with use of VA-ECMO with IABP.
Conclusion
In patients with shock requiring VA-ECMO, concurrent use of Impella and IABP had similar risk of mortality, transition to LVAD/transplant, stroke, and need for CRRT. However, Impella use was associated with higher risk of bleeding and hemolysis. Randomized trials are needed to identify the optimal strategy for left ventricular unloading in patients with cardiogenic shock on VA-ECMO.

Mitral vAlve prolapse and disjunction by cardiac maGnetIC resonance (MA-GIC) registry
Backgroung
Mitral valve prolapse (MVP) is 2-3% prevalent in the general population with good prognosis. However, some patients develop complex ventricular arrhythmias (CVAs), sudden cardiac death (SCD), or severe mitral regurgitation (MR). Previous studies suggested that bi-leaflet involvement, mitral annulus disjunction (MAD), and myocardial fibrosis (MF) are associated with adverse outcome. Notwithstanding, these findings were limited to autopsic series or single-centre studies involving highly selected patients. Moreover, MF has been scantly investigated as predictor of clinical outcome.
Purpose
To investigate the prognostic significance of MF in an international multicentre study of MVP patients studied by cardiovascular magnetic resonance (CMR) with late gadolinium enhancement (LGE).
Methods
From October 2007 to June 2020 patients undergoing LGE-CMR were screened in 14 European centres. Inclusion criteria were: i) age > 18 years; ii) full clinical history and cardiac rhythm monitoring at baseline; iii) MVP (leaflet displacement ≥ 2 mm beyond the annulus). Exclusion criteria were: i) ischemic heart disease; ii) primary cardiomyopathy; iii) inflammatory heart disease; iv) congenital heart diseases; v) moderate-to-severe valvular heart disease. CVAs at the study outset was defined as one of the following: i) ventricular ectopic beats >10000/24h; ii) ≥ 1 episode of non-sustained ventricular tachycardia (VT); iii) sustained VT; iv) aborted SCD. Primary end-point was a composite of SCD, unexplained syncope, and mitral valve repair/replacement. Secondary end-point was a composite of SCD and unexplained syncope.
Results
Four-hundred-fifty-eight MVP patients were eventually included (46 ± 16 years old, 51% males) of whom 68% had MAD. LGE was detected in 103 (22%) of subjects with mid-wall pattern (46%) in left ventricular (LV) lateral wall (66%) as the most prevalent feature. At baseline, 37% of LGE-positive patients vs. 18% of LGE-negative individuals had CVAs (P < 0.001). SVT and/or aborted SCD were more prevalent in LGE-positive than in LGE-negative patients (9% vs 2%, P < 0.001). By multivariable Cox-regression analysis, LGE presence or extent were strong independent predictors of the primary (HR = 4.02, P = 0.003 and HR = 4.76 per 10% increase, P = 0.032, respectively) and secondary (HR = 5.39, P = 0.008 and HR = 8.78 per 10% increase, P = 0.012, respectively) endpoints after correction for major confounders including LV volumes, left atrial size and MAD presence.
Conlusion
Myocardial fibrosis by LGE is the strongest independent predictor of clinical outcome in MVP. In contrast, MAD per se does not harbinger worse prognosis.

Abstract
Background Tenacibaculum maritimum is a fish pathogen known for causing serious damage to a broad range of wild and farmed marine fish populations worldwide. The recently sequenced genome of T. maritimum strain NCIMB 2154T provided unprecedented information on the possible molecular mechanisms involved in the virulence of this species. However, little is known about the dynamic of infection in vivo, and information is lacking on both the intrinsic host response (gene expression) and its associated microbiota. Here, we applied complementary omic approaches, including dual RNAseq and 16S rRNA gene metabarcoding sequencing using Nanopore and short-read Illumina technologies to unravel the host–pathogen interplay in an experimental infection system using the tropical fish Platax orbicularis as model. Results We showed that the infection of the host is characterised by an enhancement of functions associated with antibiotic and glucans catabolism functions but a reduction of sulfate assimilation process in T. maritimum. The fish host concurrently displays a large panel of immune effectors, notably involving innate response and triggering acute inflammatory response. In addition, our results suggest that fish activate an adaptive immune response visible through the stimulation of T-helper cells, Th17, with congruent reduction of Th2 and T-regulatory cells. Fish were, however, largely sensitive to infection, and less than 25% survived after 96 hpi. These surviving fish showed no evidence of stress (cortisol levels) or significant difference in microbiome diversity compared with controls at the same sampling time. The presence of T. maritimum in resistant fish skin and the total absence of any skin lesions suggest that these fish did not escape contact with the pathogen, but rather that some mechanisms prevented pathogens entry. In resistant individuals, we detected up-regulation of specific immune-related genes differentiating resistant individuals from controls at 96 hpi, which suggests a possible genomic basis of resistance, although no genetic variation in coding regions was found. Conclusion Here we focus in detail on the interplay between common fish pathogens and host immune response during experimental infection. We further highlight key actors of defence response, pathogenicity and possible genomic bases of fish resistance to T. maritimum.

Abstract
IntroductionIt has been shown that long-acting treatments can significantly improve adherence, control symptom, and reduce the risk of relapse compared to oral drugs. However, limited real world evidence is available as to whether there are differences among the various formulations marketed.ObjectivesThis study aims to assess the impact on several prognosis variables of PP1M,PP3M,AOM and OAP drugs.MethodsAll adults (≥18 years) with schizophrenia who were initiated on PP1M, PP3M, AOM, or OAP treatment (chlorpromazine,levomepromazine,fluphenazine,haloperidol,ziprasidone,zuclopenthixol,olanzapine,quetiapine,asenapine,amisulpride, risperidone,aripiprazole,paliperidone) between 2017 and 2018 were identified in IQVIA’s database(1.8M of inhabitants from 4 Spanish areas). The rate of hospitalizations, emergency room visits, and treatment persistence was calculated using the Kaplan-Meier method. Survival curves were compared using the log-rank test (Sidak-adjustment),and Cox´s Hazard Ratios (HR) were used for the comparison between groups.ResultsData from 2275 patients were analyzed (PP1M= 387;PP3M=490;AOM=75;OAP=1323).The mean age of patients was 46.8(14.95) years, and 62.9% were male. The hospitalization rate at 12 months was significantly lower (p<0.01) for PP3M (8.3%) than for AOM (21.2%), PP1M (22.1%),and OAP (29.4%).When compared with PP3M use, the HRs were 2.17 for PP1M, 2.22 for AOM,and 2.90 for OAP. Emergency room visits rate at 12 months was also significantly lower (p<0. 01) for PP3M (23%) than for PP1M (36.9%), OAP (43.5%),and AOM (46.2%). Persistence rates were higher for PP3M (91%) than for any other treatment (p<0.01).ConclusionsOur results outline that patients treated with PP3M experienced fewer relapses and decompensations compared to all other treatments analyzed, which might help improve the prognosis and quality of life of patients.Conflict of interestThis study was sponsored by Janssen.

Abstract
The unique circumstances created by the COVID-19 pandemic pose serious challenges to mood stability and emotional regulation at all ages. Although many people tend to react resiliently to stress, others appear to display emotional anxiety and depression-related symptoms. In this study, we carried out a survey (N = 10,053) during the first week of the general lockdown (quarantine) in Argentina to measure early affective reactions in Argentine adults. Respondents showed substantial anxious and depressive symptoms, with 33% and 23% of participants reporting possible depressive and anxious syndromes, respectively, with the youngest group (18 to 25 y.o.) showing the highest prevalence of symptoms. Even if prior mental health problems predisposed or aggravated the reaction, participants without prior complaints showed signs of psychological impact. Using linear regression, the most important independent variables related to depressive symptoms were the feeling of loneliness followed by daily stress. In the case of anxious states, the strongest variables were negative repetitive thinking and feeling of loneliness. Other psychological, economic, and social factors are discussed. This study is in line with previous literature that highlight the importance of the psychological impact of pandemics, but additionally demonstrates that these reactions are present at a large scale immediately after the start of quarantine with very low infectious rates as an early anticipatory adaptive reaction leading to potential negative outcomes from adjustment disorders to major disorders. In addition, the present results provide potentially relevant information about sudden environmental impacts on affective states and specific pathways for anxiety and depression to be expressed. We end by discussing implications for public policy based on considering the most vulnerable groups.

Abstract
AIMS To determine if the frequency of severe diabetic ketoacidosis at presentation of new-onset type 1 diabetes to an Australian tertiary centre increased during the initial period of restrictions resulting from the COVID-19 pandemic (March to May 2020). METHODS Data were collected on presentations of newly diagnosed type 1 diabetes as well as on all paediatric presentations to the emergency department of a tertiary centre between 2015 and 2020. Data from the period of initial COVID restrictions in Australia (March to May 2020) were compared to the period March to May of the previous 5 years (pre-pandemic periods). RESULTS The number of new diagnoses of type 1 diabetes was comparable in the pandemic period and pre-pandemic periods (11 in 2020 vs range 6-10 in 2015-2019). The frequency of severe diabetic ketoacidosis was significantly higher in the pandemic period compared to the pre-pandemic periods (45% vs 5%; P <0.003), odds ratio 16.7 (95% CI 2.0, 194.7). The overall frequency of diabetic ketoacidosis was also significantly higher during the pandemic period (73% vs 26%; P <0.007), odds ratio 7.5 (95% CI 1.7, 33.5). None of the individuals tested positive for COVID-19. Presentations of people aged <18 years to the emergency department decreased by 27% in the pandemic period compared to the average of the pre-pandemic periods (4799 vs 6550; range 6268 to 7131). CONCLUSIONS A significant increase in the frequency of severe diabetic ketoacidosis at presentation of type 1 diabetes was observed during the initial period of COVID-19 restrictions. We hypothesize that concern about presenting to hospital during a pandemic led to a delay in diagnosis. These data have important implications for advocacy of seeking healthcare for non-pandemic-related conditions during a global pandemic.

Abstract
BACKGROUND It is unclear whether modifying cholesterol, blood pressure, or both affect erectile dysfunction. Also, there are concerns that erectile dysfunction is worsened by common medications used to treat these risk factors. In this study, we evaluated the effect of: (1) cholesterol-lowering with a statin; (2) pharmacologic blood pressure reduction; and (3) their combination, on erectile function. METHODS A priori, this was a secondary analysis of the Heart Outcomes Prevention Evaluation-3 (HOPE-3) randomized controlled trial. Men were 55 years of age or older with at least 1 cardiovascular risk factor. Erectile function was measured using the erectile function domain of the International Index of Erectile Function (IIEF-EF) score. Men with incomplete scores, or who did not engage in sexual activity, were excluded. Using a 2 × 2 factorial design, participants were randomized to rosuvastatin (10 mg/d) or placebo, and to candesartan with hydrochlorothiazide (HCTZ; 16 mg/12.5 mg/d; Cand+HCTZ) or placebo. Primary outcome was change in IIEF-EF from baseline to end of study follow-up. RESULTS Two thousand one hundred fifty-three men were included; mean age was 61.5 years, and mean follow-up was 5.8 years. Mean IIEF-EF score at baseline was 23.0 (SD 5.6). Least square mean change in the IIEF-EF score did not differ with rosuvastatin compared with placebo (-1.4; standard error [SE], 0.3 vs -1.5; SE, 0.3; P = 0.74), Cand+HCTZ compared with placebo (-1.6; SE, 0.3 vs -1.3; SE, 0.3; P = 0.10), or combination therapy compared with double placebo (P = 0.35). CONCLUSIONS Cholesterol-lowering using a statin, and blood pressure-lowering using Cand+HCTZ, either alone or in combination, do not improve or adversely affect erectile function.

Abstract
In a 24-month, multicenter, open-label, randomized trial, 715 de novo kidney transplant recipients were randomized at 10-14 weeks to convert to everolimus (n = 359) or remain on standard calcineurin inhibitor (CNI) therapy (n = 356; 231 tacrolimus; 125 cyclosporine), all with mycophenolic acid and steroids. The primary endpoint, change in estimated glomerular filtration rate (eGFR) from randomization to month 12, was similar for everolimus versus CNI: mean (standard error) 0.3(1.5) mL/min/1.732 versus -1.5(1.5) mL/min/1.732 (p = 0.116). Biopsy-proven acute rejection (BPAR) at month 12 was more frequent under everolimus versus CNI overall (9.7% vs. 4.8%, p = 0.014) and versus tacrolimus-treated patients (2.6%, p < 0.001) but similar to cyclosporine-treated patients (8.8%, p = 0.755). Reporting on de novo donor-specific antibodies (DSA) was limited but suggested more frequent anti-HLA Class I DSA under everolimus. Change in left ventricular mass index was similar. Discontinuation due to adverse events was more frequent with everolimus (23.6%) versus CNI (8.4%). In conclusion, conversion to everolimus at 10-14 weeks posttransplant was associated with renal function similar to that with standard therapy overall. Rates of BPAR were low in all groups, but lower with tacrolimus than everolimus.

Abstract
BACKGROUND Although discovery research has identified the importance of dozens of pro- and anti-inflammatory immune mediators in the pathogenesis, maintenance, exacerbation and resolution of inflammatory diseases, most human cohort studies have incorporated few or no immunological intermediate phenotypes in their analyses. Significant hindrances have been (1) the limited panel of biomarkers known to be readily detected in healthy human populations and (2) the stability, hence utility, of such biomarkers to repeated analysis. METHODS The frequency and stability of 14 plasma biomarkers linked to in vivo immune regulation of allergic and autoimmune inflammatory disorders was determined in 140 healthy pediatric and adult participants. The impact of initial and multiple subsequent freeze/thaw cycles on pro-inflammatory (CCL2, CXCL10, IL-18, TNFα, IL-6), anti-inflammatory (IL-10, sTNF-RII, IL-1Ra), acute phase proteins (CRP, PTX3) and other biomarkers (sST2, IL-1RAcP) was subsequently quantified. RESULTS Multiple biomarkers capable of providing an innate immune signature of inflammation were readily detected directly ex vivo in healthy individuals. These biomarker levels were unaffected when comparing paired data sets from freshly obtained, never frozen plasma or serum and matched aliquots despite extensive freeze/thaw cycles. Neither age nor sex affected stability. Similarly, no quantitative differences were found following repetitive analysis of inflammatory biomarkers in culture samples obtained following in vitro stimulation with TLR and RLR ligands. CONCLUSIONS A broad panel of in vivo and ex vivo cytokine, chemokine and acute phase protein biomarkers that have been linked to human chronic inflammatory disorders are readily detected in vivo and remain stable for analysis despite multiple freeze thaw cycles. These data provide the foundation and confidence for large scale analyses of panels of inflammatory biomarkers to provide better understanding of immunological mechanisms underlying health versus disease.

Abstract
In this review, five strategies to estimate mycotoxin exposure of a (sub-)population via food, including data collection, are discussed with the aim to identify the added values and limitations of each strategy for risk assessment of these chemicals. The well-established point estimate, observed individual mean, probabilistic and duplicate diet strategies are addressed, as well as the emerging human biomonitoring strategy. All five exposure assessment strategies allow the estimation of chronic (long-term) exposure to mycotoxins, and, with the exception of the observed individual mean strategy, also acute (short-term) exposure. Methods for data collection, i.e. food consumption surveys, food monitoring studies and total diet studies are discussed. In food monitoring studies, the driving force is often enforcement of legal limits, and, consequently, data are often generated with relatively high limits of quantification and targeted at products suspected to contain mycotoxin levels above these legal limits. Total diet studies provide a solid base for chronic exposure assessments since they provide mycotoxin levels in food based on well-defined samples and including the effect of food preparation. Duplicate diet studies and human biomonitoring studies reveal the actual exposure but often involve a restricted group of human volunteers and a limited time period. Human biomonitoring studies may also include exposure to mycotoxins from other sources than food, and exposure to modified mycotoxins that may not be detected with current analytical methods. Low limits of quantification are required for analytical methods applied for data collection to avoid large uncertainties in the exposure due to high numbers of left censored data, i.e. with levels below the limit of quantification.

Abstract
Show the efficacy of an innovate telemedicine psyeducational invention based on a psychoeducational intervention treatment with a group of bipolar patients.ObjetivesTo assess the efficacy of an innovate telemedicine psyeducational treatment (TPT) based on a psychoeducational intervention (21 sessions) with an additional support through telemedicine which has 12 videos versus treatment as usual (TAU) based on psychiatry reviews. Specifically, the objective was to evaluate patients’ efficacy of psyeducational treatment with telemedicine (TPT) in the fuctionalitity, depressive symptoms and manic symptoms.MethodsThirty-eight patients with bipolar disorder were included in the study and randomly distributed in the two groups. The telemedine treatment is performed through a www.puedoser.es web platform provided by Astra Zeneca. In the web platform is available forums, emails and digital-course with the sessions worked as a reminder. In order to assess the effectiveness of treatments, FAST scale was administered at baseline and 6 months after the intervention. To obtain the results we used coparative data analysis.ResultsIn patients, we found a low daily functionality. The main issues were: interpersonal cognitive area (t = –2.611; P = 0.014) and interpersonal-area (t = –2.617; P = 0.014). We found, at baseline, that TPT group had worse overall results in daily functionality (t = –2.876; P = 0.008). After intervention, there is an improvement in the daily functionality of the TPT group. This improvement occurred in cognitive area (z = –3.24; P < 0.001), leisure area (z = –1.85; P = 0.065) and interpersonal area (z = –1.72; P = 0.086).ConclusionsThe psychoeducational program combined with telemedicine shows to be more effective than TAU in the improvement of general patient functioning in bipolar disorder patients.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
In a mycotoxin-dedicated total diet study (mTDS) performed in the autumn and winter of 2013 in the Netherlands, 48 mycotoxins, including patulin, aflatoxins, ochratoxin A, fumonisins, zearalenone, trichothecenes, ergot alkaloids, Alternaria toxins, beauvericin and enniatins, were quantified. Analyses were performed in 88 composite samples representative for the consumption pattern of the Dutch population. This article presents the results of the exposure assessment and subsequent risk assessment of these mycotoxins. Exposure was assessed by combining individual food consumption data obtained from the Dutch National Food Consumption Surveys (DNFCS) for young children aged 2-6 years and the population aged 7-69 years with the analytical results of the mTDS, using a lower bound and an upper bound scenario for levels below the limit of detection. Wherever possible, exposure estimates were compared with toxicological reference values, including health-based guidance values. The high level of exposure (95th percentile) exceeded the toxicological reference value regardless of the substitution scenario for ochratoxin A in the population aged 7-69 years, for the sum of T-2 and HT-2 toxins for children aged 2-6 years and for alternariol and alternariol monomethyl ether in both examined populations. The margin of exposure was too small for aflatoxin B1. For the remaining 23 mycotoxins with a toxicological reference value, the estimated exposure was below this level.

Abstract
Non-fibrillar soluble oligomeric forms of amyloid-β peptide (oAβ) and tau proteins are likely to play a major role in Alzheimer's disease (AD). The prevailing hypothesis on the disease etiopathogenesis is that oAβ initiates tau pathology that slowly spreads throughout the medial temporal cortex and neocortices independently of Aβ, eventually leading to memory loss. Here we show that a brief exposure to extracellular recombinant human tau oligomers (oTau), but not monomers, produces an impairment of long-term potentiation (LTP) and memory, independent of the presence of high oAβ levels. The impairment is immediate as it raises as soon as 20 min after exposure to the oligomers. These effects are reproduced either by oTau extracted from AD human specimens, or naturally produced in mice overexpressing human tau. Finally, we found that oTau could also act in combination with oAβ to produce these effects, as sub-toxic doses of the two peptides combined lead to LTP and memory impairment. These findings provide a novel view of the effects of tau and Aβ on memory loss, offering new therapeutic opportunities in the therapy of AD and other neurodegenerative diseases associated with Aβ and tau pathology.

Abstract
AIMS To evaluate C-reactive protein, insulin growth factor 1 and lipid levels during the follicular and luteal phases in adolescents with Type 1 diabetes. METHODS Adolescents with Type 1 diabetes (N = 40) and healthy controls (C; N = 43) were studied during the follicular and luteal phases of their menstrual cycles. C-Reactive protein, insulin growth factor 1 and lipid levels were measured. RESULTS Adolescents with Type 1 diabetes exhibited higher C-reactive protein levels than the C group during the follicular (P < 0.0001) and luteal phases (P < 0.01). The elevation of C-reactive protein levels was more pronounced in overweight adolescents with Type 1 diabetes than in adolescents in the C group. More adolescents with Type 1 diabetes were classified as having an elevated risk of cardiovascular disease (C-reactive protein > 3 mg/l) in the luteal phase than in the follicular phase (37.5% and 17.5%, respectively); half of the overweight adolescents with Type 1 diabetes in the luteal phase reached this level. BMI was the only significant factor affecting follicular and luteal phase C-reactive protein levels in adolescents with Type 1 diabetes. Lower insulin growth factor 1 levels were observed during both phases of the menstrual cycle in adolescents with Type 1 diabetes compared with controls. An elevation in insulin growth factor 1 levels in the luteal phase relative to the follicular phase was observed in controls, but not in adolescents with Type 1 diabetes. Luteal insulin growth factor 1 and C-reactive protein exhibited an inverse correlation (r = -0.4, P = 0.01). CONCLUSIONS Adolescents with Type 1 diabetes have higher C-reactive protein levels and lower insulin growth factor 1 levels relative to controls, especially during the luteal phase. Type 1 diabetes diminishes the natural elevation in insulin growth factor 1 levels observed during the luteal phase in controls. Excess weight exacerbates the subclinical inflammatory state observed during both phases of the menstrual cycle in adolescents with Type 1 diabetes.

Abstract
The recent discovery that DNA methylation survives in fossil material provides an opportunity for novel molecular approaches in palaeogenomics. Here, we apply to ancient DNA extracts the probe-independent Methylated Binding Domains (MBD)-based enrichment method, which targets DNA molecules containing methylated CpGs. Using remains of a Palaeo-Eskimo Saqqaq individual, woolly mammoths, polar bears and two equine species, we confirm that DNA methylation survives in a variety of tissues, environmental contexts and over a large temporal range (4,000 to over 45,000 years before present). MBD enrichment, however, appears principally biased towards the recovery of CpG-rich and long DNA templates and is limited by the fast post-mortem cytosine deamination rates of methylated epialleles. This method, thus, appears only appropriate for the analysis of ancient methylomes from very well preserved samples, where both DNA fragmentation and deamination have been limited. This work represents an essential step toward the characterization of ancient methylation signatures, which will help understanding the role of epigenetic changes in past environmental and cultural transitions.

Abstract
Lemongrass, Cymbopogon citratus (DC.) Stapf. (Poaceae), is grown widely in the tropics and subtropics as an ornamental, flavoring ingredient in Asian cooking, and for tea and fragrant oil (3). In February 2013, rust symptoms were observed on lemongrass in several gardens in Miami-Dade County, Florida. Symptoms began as small chlorotic flecks on both leaf surfaces that became crimson and enlarged to streaks ~1 cm in length. On the abaxial side of leaves, erumpent streaks ruptured to produce pustules in which urediniospores formed. Eventually, streaks coalesced to produce large patches of tan to purplish necrotic tissue that blighted most of the leaf surface and was often surrounded by chlorotic borders. These symptoms, fungal morphology, and nuclear ribosomal large subunit (28S) DNA analysis were used to identify the pathogen as Puccinia nakanishikii Dietel. Urediniospores were pyriform to globose, orange to crimson, slightly echinulate, and somewhat longer than a previous report (32.1 ± 3.4 (27 to 42) × 23.3 ± 2.4 (21 to 27) μm vs. 22 to 28 × 22 to 25 μm) (2). Uredinia contained clavate paraphyses, but teliospores were not observed. No aecial host is known for this pathogen. A 28S DNA sequence that was generated with the NL1 and LR3 primers (1,4) was deposited in GenBank under accession no. KC990123; it shared 99% identity with GenBank accession GU058002, which came from a specimen of P. nakanishikii in Hawaii. Voucher specimens of affected leaves of lemongrass have been deposited at the Arthur Herbarium, Purdue University. Although this disease has been reported in California, Hawaii, New Zealand, and Thailand, this is believed to be the first report from Florida (2). Based on rainfall and temperature conditions that are conducive to its development in South Florida, it has the potential to significantly reduce the health and production of this plant in area gardens.

Abstract
Impatiens, Impatiens walleriana Hook.f., are grown as an ornamental crop in greenhouse and shade house production in Florida and other regions of the United States. Downy mildew on impatiens was detected from numerous landscapes (Manatee, Hillsborough, Collier, Hendry, Broward, Palm Beach, and Miami-Dade counties) in the winter of 2012. Incidence reached nearly 100% on many affected landscape plantings. Symptoms initially appeared as yellowing on the lower leaves and were typically vein-delineated, although in some cases the entire leaf was affected. Diseased plants later wilted and infected leaves abscised from the stem. A white, downy growth was apparent on the abaxial leaf surface. Microscopic observation revealed coenocytic mycelium with sporangiophores that were hyaline, thin-walled, and had slightly swollen bases. Branches of sporangiophores were monopodial and formed right angles to the supporting branches. Sporangia were hyaline and obvoid with a single pore on the distal ends that was mostly flat. Sporangia measured 19 to 22.5 × 13 to 17 μm. Oospores were observed in stem and leaf tissue. Leaves of 10 potted impatiens plants, I. walleriana 'Super Elfin XP Coral' and 'Super Elfin XP White,' were inoculated with a suspension containing 1 × 105 sporangia/ml and sprayed till runoff (approximately 20 ml per plant) with a handheld pressurized Ulva sprayer. Plants were maintained outside in a shade house under 73% shade where the daytime temperatures averaged 24°C and RH averaged 74% and nighttime temperature averaged 18°C with an average of 91% RH. Ten non-inoculated impatiens plants served as controls. After 10 days, symptoms typical of downy mildew occurred on 100% of the inoculated impatiens plants and sporulation was confirmed microscopically. The non-inoculated control plants remained healthy. The 5' end of the large ribosomal subunit gene (762 bp) from two isolates, one collected in Hillsborough County and one from Miami-Dade County, was amplified by PCR (primers NL1-GCATATCAATAAGCGGAGGAAAAG and NL4-GGTCCGTGTTTCAAGACGG) and sequenced bi-directionally (1,2,3). The consensus sequence from both isolates was identical and it was deposited into GenBank (Accession No. JX217746). Sequence data matched (99% homology) with Plasmopara obducens reported on I. walleriana in Europe and Australia (1,2). To our knowledge, this is the first report of downy mildew on I. walleriana in Florida (4). The disease has made a major impact on impatiens in landscapes throughout Florida and will likely continue to affect future production. References: (1) A. Bulajic et. al. Plant Dis. 95:491, 2011.

Abstract
In an open-label, 24-month trial, 721 de novo heart transplant recipients were randomized to everolimus 1.5 mg or 3.0 mg with reduced-dose cyclosporine, or mycophenolate mofetil (MMF) 3 g/day with standard-dose cyclosporine (plus corticosteroids ± induction). Primary efficacy endpoint was the 12-month composite incidence of biopsy-proven acute rejection, acute rejection associated with hemodynamic compromise, graft loss/retransplant, death or loss to follow-up. Everolimus 1.5 mg was noninferior to MMF for this endpoint at month 12 (35.1% vs. 33.6%; difference 1.5% [97.5% CI: -7.5%, 10.6%]) and month 24. Mortality to month 3 was higher with everolimus 1.5 mg versus MMF in patients receiving rabbit antithymocyte globulin (rATG) induction, mainly due to infection, but 24-month mortality was similar (everolimus 1.5 mg 10.6% [30/282], MMF 9.2% [25/271]). Everolimus 3.0 mg was terminated prematurely due to higher mortality. The mean (SD) 12-month increase in maximal intimal thickness was 0.03 (0.05) mm with everolimus 1.5 mg versus 0.07 (0.11) mm with MMF (p < 0.001). Everolimus 1.5 mg was inferior to MMF for renal function but comparable in patients achieving predefined reduced cyclosporine trough concentrations. Nonfatal serious adverse events were more frequent with everolimus 1.5 mg versus MMF. Everolimus 1.5 mg with reduced-dose cyclosporine offers similar efficacy to MMF with standard-dose cyclosporine and reduces intimal proliferation at 12 months in de novo heart transplant recipients.

Abstract
Pulsed laser irradiation of damaged solids promotes ultrafast nonequilibrium kinetics, on the submicrosecond scale, leading to microscopic modifications of the material state. Reliable theoretical predictions of this evolution can be achieved only by simulating particle interactions in the presence of large and transient gradients of the thermal field. We propose a kinetic Monte Carlo (KMC) method for the simulation of damaged systems in the extremely far-from-equilibrium conditions caused by the laser irradiation. The reference systems are nonideal crystals containing point defect excesses, an order of magnitude larger than the equilibrium density, due to a preirradiation ion implantation process. The thermal and, eventual, melting problem is solved within the phase-field methodology, and the numerical solutions for the space- and time-dependent thermal field were then dynamically coupled to the KMC code. The formalism, implementation, and related tests of our computational code are discussed in detail. As an application example we analyze the evolution of the defect system caused by P ion implantation in Si under nanosecond pulsed irradiation. The simulation results suggest a significant annihilation of the implantation damage which can be well controlled by the laser fluence.

Abstract
Pachira aquatica Aubl. is a member of the Bombaceae, indigenous to Central America and northern South America. Known as the money tree within the ornamental plant industry, this tropical species is well adapted to landscapes in south Florida, Hawaii, and milder areas in southern California. Recently, it's become more popular as a potted plant for use in the interiorscape. During August 2011, several local nurseries submitted P. aquatica samples to the Florida Extension Plant Diagnostic Clinic in Homestead, FL. The foliage exhibited dark brown to black water soaked spots that became papery as the disease progressed, and rapidly enlarged and coalesced, resulting in severe leaf blight. Both young and mature leaves were affected. Phytophthora was initially confirmed by serological testing with a commercially available ImmunoStrip test (Agdia, Elkhart, IN). On closer examination, the pathogen was further identified as Phytophthora palmivora by the presence of numerous papillate, deciduous, ellipsoidal to ovoid sporangia with short pedicels. The sporangia averaged 53 × 32 μm with ranges of 48 to 59 × 29 to 35 μm (1). Phytophthora species-specific primers (pal1s and pal2a) targeting part of the 18S rRNA gene, the ITS 1, the 5.8S rRNA gene, and the ITS 2 resulted in a PCR product of 648 bp, testing positive for P. palmivora (2). The PCR product was cleaned (Qiagen Purification Kit) and sequenced (GenBank Accession No. JQ354937). The sequence from our isolate was nearly identical (exhibited 99% nucleotide identity) to an isolate of P. palmivora (GenBank Accession No. HE580280) collected from diseased cassava in China. To further support identification, phylogenetic analysis by the maximum likelihood method (Tamura-Nei model) was performed using the obtained sequence and several other Phytophthora and Pythium species from GenBank (MEGA 5.05). Our isolate grouped with other P. palmivora isolates with high support (100% bootstrap values, 1,000 replicates). Pathogenicity of the sequenced isolate was evaluated in shade house experiments. Six-month-old Pachira aquatica plants were inoculated with sporangial suspensions (1 × 106 conidia/ml) of P. palmivora. Inoculum or autoclaved water was sprayed over the foliage until runoff. Six plants were sprayed per treatment, and the experiment was repeated twice. Inoculated plants were placed in a shade house (70% shade) when temperatures ranged from 25 to 32°C with 78 to 98% relative humidity. Plants were observed for disease development, which occurred within 7 days of inoculation. No symptoms developed on the control plants. Foliar lesions closely resembled those observed in the affected nurseries and P. palmivora was reisolated from symptomatic leaf tissue. To our knowledge, on the basis of serological testing, molecular analysis, and distinguishing morphological characters, this is the first report of P. palmivora causing foliar blight of Pachira aquatica in Florida. The high incidence and severity of this disease may seriously influence local tropical foliage producers in the future. References: (1) D. C. Erwin and O. K. Ribeiro. Phytophthora Diseases Worldwide.

Abstract
Relatively large rates of response to traits of economic importance have been observed in different selection experiments in salmon. Several QTL have been mapped in the salmon genome, explaining unprecedented levels of phenotypic variation. Owing to the relatively large selection intensity, individual loci may be indirectly selected, leaving molecular footprints of selection, together with increased inbreeding, as its likely relatives will share the selected loci. We used population differentiation and levels of linkage disequilibrium in chromosomes known to be harbouring QTL for body weight, infectious pancreatic necrosis resistance and infectious salmon anaemia resistance to assess the recent selection history at the genomic level in Atlantic salmon. The results clearly suggest that the marker SSA0343BSFU on chromosome 3 (body weight QTL) showed strong evidence of directional selection. It is intriguing that this marker is physically mapped to a region near the coding sequence of DVL2 , making it an ideal candidate gene to explain the rapid evolutionary response of this chromosome to selection for growth in Salmo salar. Weak evidence of diversifying selection was observed in the QTL associated with infectious pancreatic necrosis and infectious salmon anaemia resistance. Overall, this study showed that artificial selection has produced important changes in the Atlantic salmon genome, validating QTL in commercial salmon populations used for production purposes according to the recent selection history.
