Abstract
In this research, aged plastic fragments collected from vineyards were characterized in terms of composition, residues of pesticides, and their potential to exchange these compounds with the aquatic media. To this end, we employed the qualitative and quantitative information provided by complementary analytical techniques, including chromatography, organic and inorganic mass spectrometry, infrared spectroscopy and electronic microscopy. Debris of weathered plastics were identified as polypropylene and polyethylene, containing different types of additives, from organic UV stabilizers to inorganic fillers, such as calcium salts. Regardless of polymer type, plastic litter collected from vineyards contained residues of pesticides, and particularly of fungicides, with total concentrations in the range of values from 114 ng g-1 to 76.4 μg g-1. Data obtained under different extraction conditions suggested that a fraction of these compounds was absorbed in aged polymers, penetrating inside the material. The parallel analysis of plastic litter and vineyard soils reflected higher pesticide residues in the former matrix. Furthermore, several fungicides, considered as labile in vineyard soils (i.e. zoxamide and folpet), were those showing the highest levels in plastic litter. Simulated sorption-desorption studies, with plastic debris in contact with surface water, demonstrated the higher affinity of aged materials by moderately polar pesticides than their new counterparts. For the first time, the manuscript highlights the presence of plastic litter in vineyards soils, reflecting the accumulation of several fungicides in this matrix, in some cases, with a different stability pattern to that observed in the soil from same vineyards.

Abstract
Background Behavioral weight loss programs often lead to significant short-term weight loss, but long-term weight maintenance remains a challenge. Most weight maintenance data come from clinical trials, in-person programs, or general population surveys, but there is a need for better understanding of long-term weight maintenance in real-world digital programs. Methods This observational survey study examined weight maintenance reported by individuals who had used Noom Weight, a digital commercial behavior change program, and identified factors associated with greater weight maintenance. The cross-sectional survey was completed by 840 individuals who had lost at least 10% of their body weight using Noom Weight 6-24 months prior. Results The study found that 75% of individuals maintained at least 5% weight loss after 1 year, and 49% maintained 10% weight loss. On average, 65% of initial weight loss was maintained after 1 year and 57% after 2 years. Habitual behaviors, such as healthy snacking and exercise, were associated with greater weight maintenance, while demographic factors were not. Conclusion This study provides real-world data on the long-term weight maintenance achieved using a fully digital behavioral program. The results suggest that Noom Weight is associated with successful weight maintenance in a substantial proportion of users. Future research will use a randomized controlled trial to track weight maintenance after random assignment and at a 2 year follow-up.

Abstract
BACKGROUND The Noom Weight program is a smartphone-based weight management program that uses cognitive behavioral therapy techniques to motivate users to achieve weight loss through a comprehensive lifestyle intervention. OBJECTIVE This retrospective database analysis aimed to evaluate the impact of Noom Weight use on health care resource utilization (HRU) and health care costs among individuals with overweight and obesity. METHODS Electronic health record data, insurance claims data, and Noom Weight program data were used to conduct the analysis. The study included 43,047 Noom Weight users and 14,555 non-Noom Weight users aged between 18 and 80 years with a BMI of ≥25 kg/m² and residing in the United States. The index date was defined as the first day of a 3-month treatment window during which Noom Weight was used at least once per week on average. Inverse probability treatment weighting was used to balance sociodemographic covariates between the 2 cohorts. HRU and costs for inpatient visits, outpatient visits, telehealth visits, surgeries, and prescriptions were analyzed. RESULTS Within 12 months after the index date, Noom Weight users had less inpatient costs (mean difference [MD] -US $20.10, 95% CI -US $30.08 to -US $10.12), less outpatient costs (MD -US $124.33, 95% CI -US $159.76 to -US $88.89), less overall prescription costs (MD -US $313.82, 95% CI -US $565.42 to -US $62.21), and less overall health care costs (MD -US $450.39, 95% CI -US $706.28 to -US $194.50) per user than non-Noom Weight users. In terms of HRU, Noom Weight users had fewer inpatient visits (MD -0.03, 95% CI -0.04 to -0.03), fewer outpatient visits (MD -0.78, 95% CI -0.93 to -0.62), fewer surgeries (MD -0.01, 95% CI -0.01 to 0.00), and fewer prescriptions (MD -1.39, 95% CI -1.76 to -1.03) per user than non-Noom Weight users. Among a subset of individuals with 24-month follow-up data, Noom Weight users incurred lower overall prescription costs (MD -US $1139.52, 95% CI -US $1972.21 to -US $306.83) and lower overall health care costs (MD -US $1219.06, 95% CI -US $2061.56 to -US $376.55) per user than non-Noom Weight users. The key differences were associated with reduced prescription use. CONCLUSIONS Noom Weight use is associated with lower HRU and costs than non-Noom Weight use, with potential cost savings of up to US $1219.06 per user at 24 months after the index date. These findings suggest that Noom Weight could be a cost-effective weight management program for individuals with overweight and obesity. This study provides valuable evidence for health care providers and payers in evaluating the potential benefits of digital weight loss interventions such as Noom Weight.

Abstract
BACKGROUND To evaluate drug use (alcohol, tobacco, cannabis and other drugs) and its association with mean CD4/CD8 T cell count ratio, a marker of chronic inflammation, in virally suppressed people living with HIV-1 (PLWH) in Nouvelle Aquitaine, France. METHODS A multi-centric, cross-sectional analysis was conducted in 2018-19 in the QuAliV study-ANRS CO3 AQUIVIH-NA cohort. Tobacco, alcohol, cannabis, and other drug use (poppers, cocaine, amphetamines, synthetic cathinones, GHB/GBL) were self-reported. CD4 and CD8 T cell counts and viral load measures, ± 2 years of self-report, and other characteristics were abstracted from medical records. Univariable and multivariable linear regression models, adjusted for age, sex, HIV risk group, time since HIV diagnosis, and other drug use were fit for each drug and most recent CD4/CD8 ratio. RESULTS 660 PLWH, aged 54.7 ± 11.2, were included. 47.7% [315/660] had a CD4/CD8 ratio of < 1. Their mean CD4/CD8 ratio was 1.1 ± 0.6. 35% smoked; ~ 40% were considered to be hazardous drinkers or have alcohol use disorder; 19.9% used cannabis and 11.9% other drugs. Chemsex-associated drug users' CD4/CD8 ratio was on average 0.226 (95% confidence interval [95% CI] - 0.383, - 0.070) lower than that of non-users in univariable analysis (p = 0.005) and 0.165 lower [95% CI - 0.343, 0.012] in multivariable analysis (p = 0.068). CONCLUSIONS Mean differences in CD4/CD8 ratio were not significantly different in tobacco, alcohol and cannabis users compared to non-users. However, Chemsex-associated drug users may represent a population at risk of chronic inflammation, the specific determinants of which merit further investigation.

Abstract
BACKGROUND Severe non-AIDS bacterial infections (SBIs) are one of the leading causes of hospital admissions among persons with HIV (PWH) in regions with high ART coverage. METHODS This large prospective cohort study of PWH examined the types of infections, bacterial documentation, and evolution of antibiotic resistance among PWH hospitalized with SBIs over an 18-year period. RESULTS Between 2000 and 2017, 459 PWH had at least one SBI with bacterial documentation. Among the 847 SBIs, there were 280 cases of bacteremia, 269 cases of pneumonia, and 240 urinary tract infections. The 1025 isolated bacteria included Enterobacteriaceae (n = 394; mainly Escherichia coli), Staphylococcus aureus (n = 153) and Streptococcus pneumoniae (n = 82). The proportion of S. pneumoniae as the causative agent in pneumonia and bacteremia decreased sharply over time, from 34% to 8% and from 21 to 3%, respectively.The overall antibiotic resistance of S. aureus and S. pneumoniae decreased progressively but it increased for Enterobacteriaceae (from 24% to 48% for amoxicillin-clavulanate, from 4 to 18% for cefotaxime, and from 5% to 27% for ciprofloxacin). Cotrimoxazole prophylaxis was associated with higher nonsusceptibility of S. pneumoniae to amoxicillin and erythromycin, higher nonsusceptibility of Enterobacteriaceae to beta-lactams and fluoroquinolones, and a higher risk of extended-spectrum β-lactamase producing Enterobacteriaceae. CONCLUSIONS The bacterial resistance pattern among PWH between 2014 and 2017 was broadly similar to that in the general population, with the exception of a higher resistance profile of Enterobacteriaceae to fluoroquinolones. The use of cotrimoxazole as prophylaxis was associated with an increased risk of antibiotic resistance.

Abstract
Yeast selection for the wine industry in Spain started in 1950 for the understanding of the microbial ecology, and for the selection of optimal strains to improve the performance of alcoholic fermentation and the overall wine quality. This process has been strongly developed over the last 30 years, firstly on Saccharomyces cerevisiae, and, lately, with intense activity on non-Saccharomyces. Several thousand yeast strains have been isolated, identified and tested to select those with better performance and/or specific technological properties. The present review proposes a global survey of this massive ex-situ preservation of eukaryotic microorganisms, a reservoir of biotechnological solutions for the wine sector, overviewing relevant screenings that led to the selection of strains from 12 genera and 22 species of oenological significance. In the first part, the attention goes to the selection programmes related to relevant wine-producing areas (i.e. Douro, Extremadura, Galicia, La Mancha and Uclés, Ribera del Duero, Rioja, Sherry area, and Valencia). In the second part, the focus shifted on specific non-Saccharomyces genera/species selected from different Spanish and Portuguese regions, exploited to enhance particular attributes of the wines. A fil rouge of the dissertation is the design of tailored biotechnological solutions for wines typical of given geographic areas.

Abstract
BackgroundIn patients with active systemic lupus erythematosus (SLE), circulating platelets have an activated phenotype characterized by the expression of P-selectin (CD62P). We have shown that in human SLE, platelets interact with T regulatory cells and repress their immunosuppressive functions through a P-selectin/CD15s-dependent interaction (1). Preliminary results showed that neutrophils express high level of CD15s, predicting a possible platelet/neutrophil interaction in SLE.ObjectivesInvestigate platelet/neutrophils interaction in human SLE and evaluate its impact on neutrophil functions, and lupus pathogenesis.MethodsPatients with SLE responding to the 2019 ACR/EULAR criteria were recruited for blood sampling (n = 30). Disease activity was measured using SLE disease activity index (SLEDAI-2K), and patients were considered active if SLEDAI-2K ≥ 6. Platelet-neutrophils aggregates were identified as (platelet) CD61+ (neutrophil) CD66b+ cells using flow cytometry on fresh blood samples. Single-cell cytosolic calcium and ROS imaging was performed by incubating cell with either a fluorescent calcium dye (cali-520), or a mitochondrial specific dye (MitoSox). Coverslips were mounted in an Attofluor cell chamber positioned on the stage of an inverted epifluorescence microscope (Olympus, IX70). Mitochondrial polarization of human neutrophil was evaluated by incubating cells with TMRM (100 nM) for 30 minutes. Platelet-free plasma was isolated by two sequential centrifugations (3500xg) of EDTA-anticoagulated blood and stored for subsequent evaluation of soluble P-selectin (using ELISA) and (platelet-derived) microparticular P-selectin (using flow cytometry).ResultsIn healthy donors (HD) and patients with SLE, circulating neutrophils expressed significantly higher levels of the P-selectin ligand CD15s compared to lymphoid subsets (p < 0.001), predicting platelet/neutrophil interactions. In contrast to HD and patients with inactive SLE, those with active disease had a significant increase of circulating platelet-neutrophils aggregates (p < 0.05), and these aggregates correlated with the SLEDAI (r = 0.59, p < 0.001). The incubation of human neutrophils with recombinant P-selectin induced a strong intracellular calcium signaling which was inhibited by preincubating neutrophil with anti-PSGL1 antibody (blocking P-selectin/CD15s interaction) or with a Syk kinase inhibitor. Similarly, P-selectin induced a mitochondrial ROS release in a CD15s- and Syk-dependent manner. Interestingly, incubation of neutrophils with anti-dsDNA IgG and P-selectin induced mitochondrial depolarization, which was absent with either stimulus alone. Soluble and platelet-derived microparticular P-selectin levels were significantly increased in patients with active SLE compared to inactive patients or healthy donors (p < 0.05 and p < 0.001, respectively). In a longitudinal analysis of SLE patients, soluble and microparticular P-selectin levels closely followed clinical (SLEDAI) and biological (C3 levels) markers of SLE disease activity.ConclusionP-selectin levels are increased in active SLE and follow hallmark of disease activity. P-selectin induces calcium/mitochondrial ROS signaling in lupus neutrophils which are key players in SLE pathogenesis. We hypothesize that the inhibition of P-selectin pathway might be a promising target in SLE.References[1]Scherlinger M. et al.

Abstract
OBJECTIVES The pluridisciplinary meeting "PREGNANT - Pregnancy and Auto-immunity, Nephropathy, Thrombophilic Disorders" at the university hospital of Bordeaux is dedicated to inflammatory and thrombophilic disorders during pregnancy. The objective of our study was to evaluate the quality of this meeting in terms of: compliance with the mandatory criteria, adequacy with standard care, homogeneity of care, becoming of proposals issued. METHODS We conducted a prospective observational study including patients whose files were submitted to the meeting from January 2018 to June 2019. RESULTS In all, 16 meeting were conducted with 152 cases presented. Sixty-two patients were pregnant and 90 were in preconception. The most common reasons for presentation were vasculo-placentary diseases (22.3%), systemic lupus (16.4%), venous thromboembolic diseases (15.1%) and chronic intervillositis of unknown etiology (9.8%). Other reasons were antiphospholipid antibody syndrome and repeated spontaneous miscarriages. The mandatory criteria for multidisciplinary meeting were met. For 89 cases (58.5%), the problem was dictated by recommendations. Decisions made were consistent with recommendations in 89.8% of cases. Among the 63 cases without any published recommendations (41.5%), there was some homogeneity of the proposals. In all, 92.8% of the proposals issued by the meeting were implemented. CONCLUSIONS Multidisciplinary meeting "PREGNANT" has a prominent locoregional role in the management of patients with autoimmune, inflammatory or thrombophilic disorders in a pregnancy context.

Abstract
Background:Neutrophils have been described as potent antigen-presenting cells able to activate T cells by MHC/TCR interaction and costimulatory molecules in tumor immunity. However, little is known about the direct interaction between neutrophils and CD4 T cells with respect to systemic lupus erythematosus (SLE). We have previously shown that OX40L expressed by monocytes from SLE patients promote the differentiation of naïve and memory cells into IL21 secreting T cells that are able to help B cells1,2.Objectives:In this study, we investigate OX40L expression on neutrophils from SLE patients and contribution of these OX40L+neutrophils in SLE pathogenesis to modulation of the B cell helper role of CD4 T cells.Methods:Surface expression of co-stimulatory molecules (OX40L, ICOSL, GITRL, 4-1BBL) on neutrophils from SLE patients and healthy donors (HD) was measured by flow cytometry (FC). Neutrophils from HD were stimulated with TLR7 or TLR8 agonists and IFNα after 5 hours of culture, OX40L expression was measured by FC and Western Blotting. CD4 T cells were cultured with the stimulated neutrophils for 3 days. At the end of the co-culture, percentages of IL21-expressing T follicular (Tfh) and peripheral helper (Tph) cells measured by FC. These generated T cells were also cultured in the presence of memory B cells. After 5 days of co-culture, plasmablast generation and Ig levels were assessed by FC and ELISA, respectively. Inhibition of OX40-OX40L interaction in vitro was achieved using ISB 830, a novel anti-OX40 mAb currently used in clinical trials.Results:Among the co-stimulatory molecules tested, percentages of OX40L+neutrophils in SLE (n=54) were increased compared to HD (n=25)(mean + SD: HD = 1,34%±1.62 vs SLE = 4,53%±8.1; p=0.29). OX40L expression positively correlated with SLE disease activity score (SLEDAI) (p = 0,04; r = 0,31) and with anti-DNA antibodies (p= 0,04, r = 0,33). Of note, the percentage of OX40L+neutrophils was higher in anti-sm-RNP+patients (n=16, mean= 9%±9.8), compared to anti-sm-RNP-patients (n=27, mean = 1,4%±2.5; p = 0,02). The percentage of OX40L+neutrophils was higher in patients with class III or IV lupus nephritis, and inflammatory infiltrate within the kidney biopsy disclosed OX40L+neutrophils, in close contact with T cells. Neutrophils from HD express OX40L with TLR8 agonist, or IFNα priming followed by TLR7 agonist. When memory CD4 T cells were cultured in the presence of TLR8-stimulated neutrophils, the proportion of IL21-expressing Tfh (CXCR5+PD1+) and Tph (CXCR5-PD1hi) were increased, compared to culture with unstimulated neutrophils. This process was dependent on OX40-OX40L interactions, since in vitro treatment with the anti-OX40 blocking antibody ISB 830, inhibited the differentiation of memory T cells into Tfh and Tph. Both generated Tfh and Tph were able to promote the differentiation of memory B cells into Ig-secreting plasmablasts.Conclusion:Our results disclose an unprecedented phenomenon where cross-talk between TLR7/8-activated neutrophils and CD4 lymphocytes operates through OX40L-OX40 costimulation, and neutrophils promote the differentiation of pro-inflammatory Tfh and Tph, as well as IL21 production. Therefore, OX40L/OX40 should be considered as a potentially therapeutic axis in SLE patients.References:[1]Jacquemin et al. Immunity 2015;[2]Jacquemin et al.

Abstract
BACKGROUND Plasmacytoid dendritic cells (pDCs) are a subset of dendritic cells specialized in the production of type I interferon (IFN-α/β) and involved in various cutaneous inflammatory and autoimmune disorders, such as cutaneous lupus erythematosus (CLE) and vitiligo. Heat shock proteins (HSPs) are molecular chaperones essential for maintaining cellular functions, but they can act as a danger signal during inflammation. OBJECTIVES To decipher the role of HSP70 in the production of IFN-α by pDCs in CLE and vitiligo. METHODS Expression of HSP70 and CD123+ pDCs was analysed by immunohistochemistry or immunofluorescence in CLE and vitiligo skin samples. Flow cytometry was performed to analyse expression of HSP70 receptors, activation markers on pDCs and DNA uptake by pDCs in the presence of HSP70. The impact of HSP70 on DNA-induced IFN-α secretion by pDCs was evaluated by enzyme-linked immunosorbent assay (ELISA). The effect of IFN-α on chemokine (C-X-C motif) ligand 9 (CXCL9)/10 gene and protein expression by keratinocytes was determined by real-time polymerase chain reaction and ELISA. RESULTS Infiltration of pDCs in CLE and progressive vitiligo was primarily located in the epidermis, close to keratinocytes expressing HSP70. In vitro experiments revealed that the pDCs expressing HSP70 receptor Lox-1 (lectin-like oxidized low-density lipoprotein-receptor-1) were able to aggregate HSP70. Exogenous HSP70 induced activation of pDCs and increased the uptake of exogenous DNA. Furthermore, HSP70 potentiated DNA-induced IFN-α production by pDCs. Finally, IFN-α induced expression of CXCL9 and CXCL10 by keratinocytes. CONCLUSIONS These data demonstrate that interaction between HSP70 and pDCs in CLE and vitiligo is a prerequisite for the enhancement of IFN-α production, and could be an interesting target.

Abstract
With "checkpoint inhibitors" targeting PD1/PD-1-ligands or CTLA-4/CD28 pathways, immunotherapy has profoundly modified therapeutic strategies in oncology. First approved in refractory metastatic neoplasms (melanoma and lung adenocarcinoma), it is now being tested broadly in other cancers and/or as adjuvant treatment. For a significant proportion of patients, immunotherapy is responsible for "immunological" events, identified as Immune-Related Adverse Events (irAEs). Owing to the increasing number of prescriptions, identification and management of specific immunological side effects is crucial and requires close collaboration between oncologists and internists and/or other organ specialists. Within irAEs, we propose to individualize the induced autoimmunity by the term "Opportunistic Autoimmunity Secondary to Cancer Immunotherapy" (OASI). The aims of this article are (1) to present the different available checkpoint inhibitors and the OASIs reported with these treatments and (2) to propose practical recommendations for diagnosis, pre-therapeutic assessment and management of OASIs. The need for predictive biomarkers of OASIs occurrence will also be discussed.

Abstract
Vascular cannulation is common practice in critical care, and is traditionally performed using the landmark technique - though failures and complications are not uncommon. In this regard, ultrasound guided vascular cannulation (USGVC) has been shown to improve the procedure success rate and reduce its associated complications. This review addresses the fundamental aspects of USGVC and discusses some training issues related to this technique which is currently regarded as essential for intensivists.

Abstract
Two novel 8-azabicyclo[3.2.1]octan-3-ol derivatives, 11a and 11b, with high affinity for sigma-2 receptors and a very good sigma-1/sigma-2 selectivity ratio were synthesized. In comparison with several well established sigma-2 selective ligands, 11 b showed a very low sigma-1 receptor affinity. Functional assays demonstrated that 11b acts as an agonist and in A-375 human melanoma cell line is able to lower levels of procaspase-3, thus confirming a potential major role for sigma-2 pure agonists in the treatment of rapid proliferating melanoma cells.

Abstract
BACKGROUND AND AIM Anti-tumour necrosis factor [TNF] agents have dramatically improved the prognosis of inflammatory bowel disease [IBD]. However, despite their good safety profile, use of these agents may lead to paradoxical manifestations involving skin or joints. Pathogenesis of such side effects is poorly understood and may involve anti-TNF pharmacokinetics. The aim of the present study was to look for an association between infliximab trough levels [ITL] and cutaneous [CPM] or rheumatological [RPM] paradoxical manifestations. METHODS IBD patients receiving infliximab as maintenance therapy were included in a cross-sectional prospective monocentre study. At inclusion, patients had an ITL measurement [LISA-TRACKER®, Biomedical Diagnostics BMD] and were assessed for paradoxical manifestations: a CPM was defined by new onset or exacerbation of pre-existing psoriasis lesions during IFX therapy, and an RPM by new onset of severe poly-arthralgia during IFX therapy. RESULTS Among the 121 patients included [69 female; median age: 38.9 years; 92 with Crohn's disease], 7% had CPM and 8% RPM. Median ITL values were 5.87 [range: 0.52-19.53] µg/ml in patients with CPM and 1.90 [0.00-13.5] µg/ml in those with RPM, as compared respectively with 5.12 [0.00-49.12] µg/ml in patients without CPM [p = 0.56] and 5.57 [0.00-49.12] µg/ml in those without RPM [p = 0.058]. No prognostic factor was associated with CPM. The single factor associated with RPM was elevated antinuclear antibodies. CONCLUSION ITL were not elevated in IBD patients developing cutaneous or rheumatological paradoxical manifestations when receiving IFX as maintenance therapy. As suggested by the high level of antinuclear antibodies, RPM could be related to an induced autoimmune disorder.

Abstract
OBJECTIVE The aim of this study was to evaluate the effect of hydroxychloroquine (HCQ) on fetal preterm delivery and intrauterine growth restriction (IUGR) in a cohort of pregnant women with systemic lupus erythematosus (SLE). METHODS Over an 11-year period (January 1, 2001 to December 31, 2011), all women with SLE and admitted to deliver after 22 weeks of gestation to Bordeaux University Hospital (France), were retrospectively enrolled in the present study. The population was then split into two groups based on the treatment they received: HCQ exposed (HCQ+) versus HCQ non-exposed (HCQ-) group. RESULTS 118 pregnancies were included, 41 in the HCQ+ group and 77 in the HCQ- group. The rate of adverse fetal outcome was significantly lower in the HCQ+ group (p = 0.001), particularly in terms of preterm delivery, 15.8% versus 44.2% (p = 0.006), and IUGR, 10.5% versus 28.6% (p = 0.03). No adverse outcomes were reported in the HCQ+ group. CONCLUSION HCQ reduces neonatal morbidity in women with SLE by significantly decreasing the rate of prematurity and intrauterine growth restriction.

Abstract
Orujo is a traditional alcoholic beverage produced in Galicia (northwest Spain) from distillation of grape pomace, a byproduct of the winemaking industry. In this study, the effect of the distillation system (copper charentais alembic versus packed column) and the yeast strain (native yeast L1 versus commercial yeast L2) on the chemical and sensory characteristics of orujo obtained from Albariño (Vitis vinifera L.) grape pomace has been analyzed. Principal component analysis, with two components explaining 74% of the variance, is able to clearly differentiate the distillates according to distillation system and yeast strain. Principal component 1, mainly defined by C6-C12 esters, isoamyl octanoate, and methanol, differentiates L1 from L2 distillates. In turn, principal component 2, mainly defined by linear alcohols, linalool, and 1-hexenol, differentiates alembic from packed column distillates. In addition, an aroma descriptive test reveals that the distillate obtained with a packed column from a pomace fermented with L1 presented the highest positive general impression, which is associated with the highest fruity and smallest solvent aroma scores. Moreover, chemical analysis shows that use of a packed column increases average ethanol recovery by 12%, increases the concentration of C6-C12 esters by 25%, and reduces the concentration of higher alcohols by 21%. In turn, L2 yeast obtained lower scores in the alembic distillates aroma profile. In addition, with L1, 9% higher ethanol yields were achieved, and L2 distillates contained 34%-40% more methanol than L1 distillates.

Abstract
The authors designed a risk-based approach to the selection of poultry flocks to be sampled in order to further improve the sensitivity of avian influenza (AI) active surveillance programme in Cuba. The study focused on the western region of Cuba, which harbours nearly 70% of national poultry holdings and comprise several wetlands where migratory waterfowl settle (migratory waterfowl settlements - MWS). The model took into account the potential risk of commercial poultry farms in western Cuba contracting from migratory waterfowl of the orders Anseriformes and Charadriiformes through dispersion for pasturing of migratory birds around the MWS. We computed spatial risk index by geographical analysis with Python scripts in ESRI(®) ArcGIS 10 on data projected in the reference system NAD 1927-UTM17. Farms located closer to MWS had the highest values for the risk indicator pj and in total 31 farms were chosen for targeted surveillance during the risk period. The authors proposed to start active surveillance in the study area 3 weeks after the onset of Anseriformes migration, with additional sampling repeated twice in the same selected poultry farms at 15 days interval (Comin et al., 2012; EFSA, 2008) to cover the whole migration season. In this way, the antibody detectability would be favoured in case of either a posterior AI introduction or enhancement of a previous seroprevalence under the sensitivity level. The model identified the areas with higher risk for AIV introduction from MW, aiming at selecting poultry premises for the application of risk-based surveillance. Given the infrequency of HPAI introduction into domestic poultry populations and the relative paucity of occurrences of LPAI epidemics, the evaluation of the effectiveness of this approach would require its application for several migration seasons to allow the collection of sufficient reliable data.

Abstract
PURPOSE To evaluate in France the annual direct medical cost of adult patients with active systemic lupus erythematosus (SLE) on medication and estimate the cost of a flare. METHODS A two-year, observational, retrospective, multicenter study, carried out between December 2010 and February 2011. Patients' characteristics, SLE disease activity and severity, rate of flares, healthcare consumption (medications, hospitalisations, etc.) were evaluated. Medical costs were assessed from the national Health Insurance perspective. Cost predictors were estimated using multivariate regression models. RESULTS Eight centres specialized in SLE management included 93 eligible patients (including 50.5% severe). The mean age was 39.9 (11.9) years and 93.5% were women. At baseline, the mean SLE duration was 9.8 (6.6) years. The mean scores of the SELENA-SLEDAI instrument and the SLICC/ACR index were higher in severe patients (9.8 vs 5.6, and 1.2 vs 0.4 respectively; P<0.001). Over the study period, 51% of patients received the combination containing at least corticosteroids or immunosuppressants. The mean annual direct medical cost of severe patients was €4660 versus €3560 for non-severe patients (non-significant difference). The cost of medications (61.8% of the annual cost) was higher in severe patients (€3214 vs €1856; P<0.05). Immunosuppressants and biologics represented 26.5% and 4.6% of the annual total cost respectively. Patients experienced on average 1.10 (0.59) flares/year, of which 0.50 were severe flare. The occurrence of a new severe flare incremented the annual cost of €1330 (P<0.05). CONCLUSION Medications represented the major component of the annual direct medical cost. Severe flares increase significantly the cost of SLE care management.
