Abstract
Forests in Europe are exposed to increasingly frequent and severe disturbances. The resulting changes in the structure and composition of forests can have profound consequences for the wildlife inhabiting them. Moreover, wildlife populations in Europe are often subjected to differential management regimes as they regularly extend across multiple national and administrative borders. The red deer Cervus elaphus population in the Bohemian Forest Ecosystem, straddling the Czech-German border, has experienced forest disturbances, primarily caused by windfalls and bark beetle Ips typographus outbreaks during the past decades. To adapt local management strategies to the changing environmental conditions and to coordinate them across the international border, reliable estimates of red deer density and abundance are highly sought-after by policymakers, wildlife managers, and stakeholders. Covering a 1081-km2 study area, we conducted a transnational non-invasive DNA sampling study in 2018 that yielded 1578 genotyped DNA samples from 1120 individual red deer. Using spatial capture-recapture models, we estimated total and jurisdiction-specific abundance of red deer throughout the ecosystem and quantified the role of forest disturbance and differential management strategies in shaping spatial heterogeneity in red deer density. We hypothesised that (a) forest disturbances provide favourable habitat conditions (e.g., forage and cover), and (b) contrasting red deer management regimes in different jurisdictions create a differential risk landscape, ultimately shaping density distributions. Overall, we estimated that 2851 red deer (95% Credible Interval = 2609-3119) resided in the study area during the sampling period, with a relatively even overall sex ratio (1406 females, 95% CI = 1229-1612 and 1445 males, 95% CI = 1288-1626). The average red deer density was higher in Czechia (3.5 km-2, 95% CI = 1.2-12.3) compared to Germany (2 km-2, 95% CI = 0.2-11). The effect of forest disturbances on red deer density was context-dependent. Forest disturbances had a positive effect on red deer density at higher elevations and a negative effect at lower elevations, which could be explained by partial migration and its drivers in this population. Density of red deer was generally higher in management units where hunting is prohibited. In addition, we found that sex ratios differed between administrative units and were more balanced in the non-intervention zones. Our results show that the effect of forest disturbances on wild ungulates is modulated by additional factors, such as elevation and ungulate management practices. Overall density patterns and sex ratios suggested strong gradients in density between administrative units. With climate change increasing the severity and frequency of forest disturbances, population-level monitoring and management are becoming increasingly important, especially for wide-ranging species as both wildlife and global change transcend administrative boundaries.

Abstract
Stable isotope analysis of individual compounds is emerging as a powerful tool to study nutrient origin and conversion in host-parasite systems. We measured the carbon isotope composition of amino acids and glucose in the cestode Schistocephalus solidus and in liver and muscle tissues of its second intermediate host, the three-spined stickleback (Gasterosteus aculeatus), over the course of 90 days in a controlled infection experiment. Similar linear regressions of δ13C values over time and low trophic fractionation of essential amino acids indicate that the parasite assimilates nutrients from sources closely connected to the liver metabolism of its host. Biosynthesis of glucose in the parasite might occur from the glucogenic precursors alanine, asparagine and glutamine and with an isotope fractionation of - 2 to - 3 ‰ from enzymatic reactions, while trophic fractionation of glycine, serine and threonine could be interpreted as extensive nutrient conversion to fuel parasitic growth through one-carbon metabolism. Trophic fractionation of amino acids between sticklebacks and their diets was slightly increased in infected compared to uninfected individuals, which could be caused by increased (immune-) metabolic activities due to parasitic infection. Our results show that compound-specific stable isotope analysis has unique opportunities to study host and parasite physiology.

Abstract
Temperature is an important environmental modulator of teleost immune activity. Susceptibility of teleosts to temperature variation depends on the species-specific adaptive temperature range, and the activity of the teleost immune system is generally temperature-dependent. Similar to many physiological and metabolic traits of ectotherms, temperature modulates the activity of immune traits. At low temperatures, acquired immunity of many teleost species is down-modulated, and their immuno-competence mainly depends on innate immunity. At intermediate temperatures, both innate and acquired immunity are fully active and provide optimal protection, including long-lasting immunological memory. When temperatures increase and reach the upper permissive range, teleost immunity is compromised. Moreover, temperature shifts may have negative effects on teleost immune functions, in particular if shifts occur rapidly with high amplitudes. On the contrary, short-term temperature increase may help teleost immunity to fight against pathogens transiently. A major challenge to teleosts therefore is to maintain immuno-competence throughout the temperature range they are exposed to. Climate change coincides with rising temperatures, and more frequent and more extreme temperature shifts. Both are likely to influence the immuno-competence of teleosts. Nonetheless, teleosts exist in habitats that differ substantially in temperature, ranging from below zero in the Arctic's to above 40°C in warm springs, illustrating their enormous potential to adapt to different temperature regimes. The present review seeks to discuss how changes in temperature variation, induced by climate change, might influence teleost immunity.

Abstract
Interpretation of stable isotope data is of upmost importance in ecology to build sound models for the study of animal diets, migration patterns and physiology. However, our understanding of stable isotope fractionation and incorporation into consumer tissues is still limited. We therefore measured the δ13C values of individual amino acids over time from muscle and liver tissue of three-spined sticklebacks (Gasterosteus aculeatus) on a high protein diet. The δ13C values of amino acids in the liver quickly responded to small shifts of under ± 2.0‰ in dietary stable isotope compositions on 30-day intervals. We found on average no trophic fractionation in pooled essential (muscle, liver) and non-essential (muscle) amino acids. Negative Δδ13C values of − 0.7 ± 1.3‰ were observed for pooled non-essential (liver) amino acids and might indicate biosynthesis from small amounts of dietary lipids. Trophic fractionation of individual amino acids is reported and discussed, including unusual Δδ13C values of over + 4.9 ± 1.4‰ for histidine. Arginine and lysine showed the lowest trophic fractionation on individual sampling days and might be useful proxies for dietary sources on short time scales. We suggest further investigations using isotopically enriched materials to facilitate the correct interpretation of ecological field data.

Abstract
Introduction Les inégalités sociales sont fortement associées aux inégalités de santé, que ce soit pour les maladies chroniques ou infectieuses. Le SARS-CoV-2 ne fait pas exception, l'étude nationale EpiCov ayant montré dès juin 2020 un risque de COVID-19 croissant avec la défavorisation sociale. Le dépistage demeure un des piliers du contrôle de cette pandémie, tant à l'échelle individuelle pour l'isolement des cas et de leurs contacts à risque, que populationnelle pour identifier et cibler certaines mesures d'accompagnement. L'accès au dépistage ne saurait être considéré comme uniforme, tant l'accès au soin apparaît déficitaire dans certains territoires (zones urbaines défavorisées, rurales). Par ailleurs, le manque de prise en compte des inégalités sociales dans les mesures de suivi des cas a été souligné. Notre objectif était de prendre en compte le sous-diagnostic du SARS-CoV-2 lié à la défavorisation sociale afin d'améliorer le ciblage des actions de santé publique à l'échelle régionale. Matériels et méthodes Le nombre de tests (RT-PCR et antigéniques) et de cas de COVID-19 positifs enregistrés dans la base SI-DEP ont été agrégées à l'échelle spatiale des IRIS (subdivision géographique d'environ 2000 habitants) et temporelle selon des périodes correspondant aux grandes mesures de contrôle de l'épidémie (pré-, pendant, post-confinement, passe sanitaire…). Les taux de dépistage, d'incidence de COVID-19 et de positivité des tests ont été définis par IRIS et par période. Nous avons caractérisé le profil socio-démographique de chaque IRIS à partir de données de population et d'accès au soin (source INSEE et DREES), et de l'European Deprivation Index (EDI), indicateur spécifique de défavorisation sociale. Enfin, nous avons analysé le ratio de taux de dépistage (RTD) selon le profil socio-démographique après ajustement sur l'accès au soin, au moyen d'un modèle additif généralisé hiérarchique prenant en compte l'autocorrélation spatiale entre les IRIS voisins. Résultats Nous avons distingué 10 périodes entre Juillet 2020 et Janvier 2022, et identifié six profils d'IRIS : un profil rural, un rural/péri-urbain, et quatre profils urbains correspondant respectivement à des IRIS aisés, denses de centre-ville, défavorisées, et denses très défavorisées. Le taux de dépistage des IRIS urbains très défavorisés était systématiquement inférieur au taux de dépistage des IRIS urbains/péri-urbains aisés (RTD entre 0.85 (IC95 %=0.80-0.91) et 0.64 (0.59-0.69)). Les pics d'incidence de COVID-19 ont été atteints plus tardivement dans les IRIS très défavorisées que dans les IRIS aisés lors de périodes de confinement (novembre 2020) ou de périodes de vaccination massive (juillet 2021). Conclusion Cette étude a permis d'identifier une liste limitée d'IRIS caractérisés par un sous-dépistage et un retard d'efficacité des mesures sanitaires de freinage de la COVID-19. Ils ont ainsi pu être priorisés dans les interventions mises en place par les acteurs régionaux et locaux de la réponse à la pandémie. Aucun lien d'intérêt

Abstract
Density is a key trait of populations and an essential parameter in ecological research, wildlife conservation and management. Several models have been developed to estimate population density based on camera trapping data, including the random encounter model (REM) and camera trap distance sampling (CTDS). Both models need to account for variation in animal behavior that depends, for example, on the species and sex of the animals along with temporally varying environmental factors. We examined whether the density estimates of REM and CTDS can be improved for Europe’s most numerous deer species, by adjusting the behavior-related model parameters per species and accounting for differences in movement speeds between sexes, seasons, and years. Our results showed that bias through inadequate consideration of animal behavior was exceeded by the uncertainty of the density estimates, which was mainly influenced by variation in the number of independent observations between camera trap locations. The neglection of seasonal and annual differences in movement speed estimates for REM overestimated densities of red deer in autumn and spring by ca. 14%. This GPS telemetry-derived parameter was found to be most problematic for roe deer females in summer and spring when movement behavior was characterized by small-scale displacements relative to the intervals of the GPS fixes. In CTDS, density estimates of red deer improved foremost through the consideration of behavioral reactions to the camera traps (avoiding bias of max. 19%), while species-specific delays between photos had a larger effect for roe deer. In general, the applicability of both REM and CTDS would profit profoundly from improvements in their precision along with the reduction in bias achieved by exploiting the available information on animal behavior in the camera trap data.

Abstract
Global climate change can influence organismic interactions like those between hosts and parasites. Rising temperatures may exacerbate the exploitation of hosts by parasites, especially in ectothermic systems. The metabolic activity of ectotherms is strongly linked to temperature and generally increases when temperatures rise. We hypothesized that temperature change in combination with parasite infection interferes with the host's immunometabolism. We used a parasite, the avian cestode Schistocephalus solidus, which taps most of its resources from the metabolism of an ectothermic intermediate host, the three-spined stickleback. We experimentally exposed sticklebacks to this parasite, and studied liver transcriptomes 50 days after infection at 13°C and 24°C, to assess their immunometabolic responses. Furthermore, we monitored fitness parameters of the parasite and examined immunity and body condition of the sticklebacks at 13°C, 18°C and 24°C after 36, 50 and 64 days of infection. At low temperatures (13°C), S. solidus growth was constrained, presumably also by the more active stickleback's immune system, thus delaying its infectivity for the final host to 64 days. Warmer temperature (18°C and 24°C) enhanced S. solidus growth, and it became infective to the final host already after 36 days. Overall, S. solidus produced many more viable offspring after development at elevated temperatures. In contrast, stickleback hosts had lower body conditions, and their immune system was less active at warm temperature. The stickleback's liver transcriptome revealed that mainly metabolic processes were differentially regulated between temperatures, whereas immune genes were not strongly affected. Temperature effects on gene expression were strongly enhanced in infected sticklebacks, and even in exposed-but-not-infected hosts. These data suggest that the parasite exposure in concert with rising temperature, as to be expected with global climate change, shifted the host's immunometabolism, thus providing nutrients for the enormous growth of the parasite and, at the same time suppressing immune defence.

Abstract
Abstract
In July 2018, one autochthonous case of West Nile virus (WNV) infection was identified in Nice, Provence-Alpes-Côte d’Azur (Paca). We investigated to determine the potential place of infection and the extent of viral circulation in the area, in order to guide control and preventive measures. In affected areas, we raised awareness of health professionals on WNV infections, substance of human origin safety relied on nucleic acid testing for WNV and on deferral of blood donors indicating minimum one night of stay in the areas for 28 days. Equine, wild bird and entomologic surveillance activities were reinforced. The human arboviruses national reference laboratory (NRL) retrospectively tested samples from hospitalized individuals from June 1st with meningitis and encephalitis around Nice. We tested negative suspected autochthonous cases of chikungunya and dengue infections notified since July in Paca and presenting WNV compatible symptoms. Measures were adapted along identification of additional cases.
We identified 27 autochthonous cases, with onset of symptoms between July 7th and November 12th: 24 in Paca, 2 in Corsica and 1 in Occitanie. Seven cases presented neuroinvasives symptoms, 18 flu-like symptoms and 2 were asymptomatic. One blood donation and 2 organs tested positive for WNV. The animal NRL identified 13 equine cases (1 in Paca, 5 in Corsica and 7 in Occitanie) and 4 infected raptors with nervous symptoms (3 in Paca and 1 in Corsica). Genomic characterization of the virus identified a strain belonging to the lineage 2 among 2 raptors. No virus was found in mosquitoes captured in affected areas.
Since 2000, six episodes of WNV transmission were reported in France but none with this extent. For the first time, the lineage 2, circulating in Italy and other European countries, was isolated in France which might be changing epidemiological situation. Therefore, surveillance activities should be revised in order to promptly secure blood products.
Key messages
We describe the most important episode of West Nile Virus transmission identified in humans in France. In 2018, West Nile virus lineage 2 was isolated for the first time in France which might change the epidemiological situation in the country.

Abstract
Abstract
Background
Aedes albopictus, vector of dengue and chikungunya viruses, is implanted in mainland France, exposing to the risk of autochthonous transmission. Since 2006, epidemiological and entomological surveillance activities aim to prevent or limit the occurrence of autochthonous cases. We aimed to describe episodes of transmission and control measures implemented in order to reflect on surveillance activities.
Methods
We reviewed all publications and documents produced on autochthonous transmission episodes in France and surveillance protocols. We reviewed surveillance activities, investigation methods and control measures implemented.
Results
Between 2010 and 2018, eight episodes of autochthonous dengue fever transmission and three of chikungunya were recorded in mainland France. All of them occurred in the South east of France, between July and October, when vector density was the highest. Transmission areas were limited to single domestic houses located in discontinuous urban areas. Only two episodes happened in two distinct areas. Chikungunya episodes led to 31 cases and dengue fever episodes to 23 cases. Most cases were identified by door-to-door investigations set-up in transmission areas. We isolated serotypes 1 and 2 for dengue and East Central South Africa lineage for chikungunya in autochthonous cases. Adulticide vector control measures were effective in controlling transmission.
Seven episodes of transmission were due to failure in identifying primary imported cases. Four episodes occurred because of the absence or the lack of vector controls measures around primary imported cases.
Conclusions
Surveillance activities, and autochthonous cases investigations, were effective in limiting the extent of transmission, but were highly demanding for surveillance actors. Identified causes of transmission highlight the need of regular awareness campaigns targeting physicians and biologists.
Key messages
Effectiveness of the surveillance system of dengue, chikungunya and zika viruses, and autochthonous cases investigations. Needs of awareness and training courses targeting health professionals to the risk represented by these viruses.

Abstract
Abstract
Background
Measles’ outbreaks still occur in industrialised countries and reactive monitoring of the disease is needed. In France, measles’ monitoring is based on a mandatory notification (MN).
Methods
In France, for each emergency department (ED) visit, an Electronic ED Abstract (EEDA) is transmitted to the OSCOUR® network included in national Syndromic Surveillance System. EEDA include the diagnosis at discharge using International Classification of Disease (ICD-10). This study aims to evaluate the correlation between the number of measles MN and the number of ED visits related to measles and to calculate the positive predictive value (PPV) of diagnosis at discharge of measles in ED. The study period covered the third wave of the 2008-2011 French outbreak. From 2010 to 2011, we analyzed EEDA transmitted from 32/53 ED of the PACA region and regional measles MN. Using weekly aggregated data, the correlation between the number of measles cases given by both MN and ED sources was assessed (Pearson coefficient). In the 4 ED (2 pediatric) of the teaching hospital of Marseille, electronic medical files coded as measles were reviewed to evaluate the PPV of the diagnosis coded according to the national MN case definition (gold standard).
Results
2,949 MN were transmitted and 1,306/1.3 million visits in ED were coded as measles. The peak of the outbreak was reported the same week by EEDA and MN. The correlation between EEDA and MN was strong (0.91; p < 0.001). Hospitalization rate was 20.7% and 21.0% according to EEDA and MN (p = 0.81). Among 363 medical files coded as measles in the 4 ED, 14 cases (3.9%) did not fulfilled the national case definition (PPV: 96.1 [IC95%: 94.2-98.1]), 86 (23.7%) fulfilled criteria for “clinical case” and 263 (72.5%) for “confirmed case".
Conclusions
Most of the time, ED visits coded as measles fulfilled diagnosis criteria. Our results suggested that EEDA (better reactivity) could be complementary to MN (better completeness) to monitor measles.
Key messages
Most of the time, ED visits coded as measles fulfilled diagnosis criteria: PPV of coded medical diagnosis in ED for measles is high. Reactivity of ED data monitoring could usefully complete mandatory notification for measles surveillance.

Abstract
The majority of parasites have evolved strategies to evade the immune responses of their hosts. Neuroactive substances produced by cestodes are possible candidate molecules for regulating host immune responses. The neurons of helminths can synthesize a wide range of molecules that are identical to the ones functioning in their host organisms, and host lymphocytes have receptors for these neuroactive substances. We hypothesized that in teleost fish, antihelminthic immune responses are regulated via 5-hydroxytryptamine (5-HT, or serotonin) and γ-aminobutyric acid (GABA). In the present study, we investigated the in vitro influence of serotonin, GABA and Schistocephalus solidus (helminth) antigens on basic characteristics of the three-spined stickleback Schistocephalus solidus cellular immune response. Head kidney leucocytes (HKLs) were analysed by flow cytometry for cell viability and the frequency of leucocyte subsets (the granulocyte-to-lymphocyte ratio) and by a chemiluminescence assay for the production of reactive oxygen species (ROS). In short-term (2-h) HKL cultures, 5-HT did not change the total numbers of live HKLs, but the production of ROS decreased significantly with all 5-HT concentrations. In long-term (96-h) cultures, high 5-HT concentrations induced a decrease in leucocyte viability. This coincided with elevated ROS production in cultures with all 5-HT concentrations. In short-term (2-h) HKL cultures, GABA did not change the total numbers of live HKLs, but the production of ROS decreased significantly with high (100 nmol L-1) GABA concentrations. In long-term (96-h) cultures, high and medium concentrations of GABA (100 nmol L-1 and 10 nmol L-1) elevated the numbers of live HKLs compared to controls. The granulocyte-to-lymphocyte ratios generally increased upon exposure to GABA at all concentrations. All concentrations of GABA alone elevated the ROS production of HKLs compared to controls. In the present work, we showed that the neuroactive substances serotonin and GABA regulate the teleost immune system. Our study supports the hypothesis that these substances might be immunomodulators in tapeworm-fish parasite-host interactions.

Abstract
Abstract
Background: Younger patients (pts) with breast cancer may experience more aggressive disease and are more likely to die from their cancer vs older pts. In the Phase III MONALEESA-7 study (NCT02278120), the addition of ribociclib (RIB; cyclin-dependent kinase 4/6 inhibitor) to a non-steroidal aromatase inhibitor (NSAI) or tamoxifen (TAM) + goserelin significantly prolonged progression-free survival (PFS) in premenopausal women with hormone receptor-positive (HR+), HER2-negative (HER2–) advanced breast cancer (ABC; hazard ratio 0.553; p<0.0001). RIB treatment benefit was observed irrespective of endocrine partner (NSAI or TAM). Here we report results from a MONALEESA-7 subgroup analysis in pts aged <40 yrs and ≥40 yrs who received RIB or placebo (PBO) in combination with an NSAI + goserelin.
Methods: Pre- or perimenopausal women with HR+, HER2– ABC who had received no prior endocrine therapy and ≤1 line of chemotherapy for ABC were enrolled. Of the 672 pts randomized, 495 (74%) received RIB (600 mg/day, 3-weeks-on/1-week-off) or PBO + an NSAI (letrozole [2.5 mg/day] or anastrozole [1 mg/day]) and goserelin (3.6 mg every 28 days). The primary endpoint was locally assessed PFS; secondary endpoints included overall response rate (ORR), clinical benefit rate (CBR), and safety. A prespecified subgroup analysis was performed in pts aged <40 yrs and ≥40 yrs.
Results: A total of 144 pts were aged <40 yrs (RIB vs PBO arm: 78 vs 66) and 351 were aged ≥40 yrs (170 vs 181). As of August 20, 2017, in the RIB vs PBO arms, treatment was ongoing in 50% vs 23% of pts aged <40 yrs and 54% vs 43% of pts aged ≥40 yrs; disease progression was the most common reason for treatment discontinuation (<40 yrs: 37% vs 68%; ≥40 yrs: 35% vs 44%). Median PFS was prolonged in the RIB vs PBO arms both in pts aged <40 yrs (not reached vs 10.8 months; hazard ratio 0.435; 95% confidence interval [CI] 0.276–0.686) and in pts aged ≥40 yrs (27.5 vs 19.1 months; hazard ratio 0.625; 95% CI 0.449–0.870). In pts with measurable disease, the ORR (RIB vs PBO arm) was 49% vs 32% in pts aged <40 yrs and 51% vs 38% in pts aged ≥40 yrs; CBR was 81% vs 61% and 82% vs 65%, respectively. The most common Grade 3 adverse events (AEs; ≥5% of pts in either arm; RIB vs PBO arm) were neutropenia (<40 yrs: 47% vs 5%; ≥40 yrs: 58% vs 3%), leukopenia (<40 yrs: 18% vs 2%; ≥40 yrs: 14% vs 1%), diarrhea (<40 yrs: 5% vs 0; ≥40 yrs: 1% vs 0), and increased alanine aminotransferase (<40 yrs: 4% vs 2%; ≥40 yrs: 5% vs 1%); neutropenia was the only Grade 4 AE occurring in ≥5% of pts in either arm (<40 yrs: 15% vs 0; ≥40 yrs: 8% vs 1%). New post-baseline QTcF >480 ms (RIB vs PBO arm) occurred in 3% vs 2% of pts aged <40 yrs and 7% vs 1% of pts aged ≥40 yrs.
Conclusions: Consistent treatment benefit was observed with RIB + NSAI vs PBO + NSAI in premenopausal women with HR+, HER2– ABC irrespective of age. RIB + NSAI had a manageable safety profile in pts aged <40 yrs and in those aged ≥40 yrs, with a safety profile similar to that observed in the full study population.

Abstract
Parasitic helminths have evolved strategies to evade their host's immune systems. Particularly, the early time of interactions between helminths and their hosts might be decisive for their infection success. We used the cestode Schistocephalus solidus, and its highly specific second intermediate host, the three-spined stickleback (Gasterosteus aculeatus) to investigate parasite infection and host cellular immune responses starting 1 day postexposure (dpe). We recovered live parasites from stickleback body cavities already 24 hr after exposure. Infection rates increased up to 50% and did not change from 4 dpe onwards. Thus, not all parasites had reached the body cavity at the early time points and clearance of the parasite at later time points did not occur. Stickleback head kidney leucocytes (HKLs) did not show distinct signs of activation and lymphocyte proliferation, granulocyte-to-lymphocyte ratios and respiratory burst activity of infected sticklebacks did not deviate from controls significantly. The immune system was activated only late, as indicated by an increase in the total count of HKL relative to stickleback weight (HKL per mg fish), which was significantly elevated in infected fish 32 dpe. S. solidus seems to evade leucocyte activity early during infection facilitating its establishment in the hosts' body cavity.

Abstract
Background Increasing temperatures are predicted to strongly impact host-parasite interactions, but empirical tests are rare. Host species that are naturally exposed to a broad temperature spectrum offer the possibility to investigate the effects of elevated temperatures on hosts and parasites. Using three-spined sticklebacks, Gasterosteus aculeatus L., and tapeworms, Schistocephalus solidus (Müller, 1776), originating from a cold and a warm water site of a volcanic lake, we subjected sympatric and allopatric host-parasite combinations to cold and warm conditions in a fully crossed design. We predicted that warm temperatures would promote the development of the parasites, while the hosts might benefit from cooler temperatures. We further expected adaptations to the local temperature and mutual adaptations of local host-parasite pairs. Results Overall, S. solidus parasites grew faster at warm temperatures and stickleback hosts at cold temperatures. On a finer scale, we observed that parasites were able to exploit their hosts more efficiently at the parasite’s temperature of origin. In contrast, host tolerance towards parasite infection was higher when sticklebacks were infected with parasites at the parasite’s ‘foreign’ temperature. Cold-origin sticklebacks tended to grow faster and parasite infection induced a stronger immune response. Conclusions Our results suggest that increasing environmental temperatures promote the parasite rather than the host and that host tolerance is dependent on the interaction between parasite infection and temperature. Sticklebacks might use tolerance mechanisms towards parasite infection in combination with their high plasticity towards temperature changes to cope with increasing parasite infection pressures and rising temperatures.

Abstract
The evolutionary arms race of hosts and parasites often results in adaptations, which may differ between populations. Investigation of such local adaptation becomes increasingly important to understand dynamics of host-parasite interactions and co-evolution. To this end we performed an infection experiment involving pairs of three-spined sticklebacks and their tapeworm parasite Schistocephalus solidus from three geographically separated origins (Germany, Spain and Iceland) in a fully-crossed design for sympatric and allopatric host/parasite combinations. We hypothesized that local adaptation of the hosts results in differences in parasite resistance with variation in parasite infection rates and leukocyte activation, whereas parasites from different origins might differ in virulence reflected in host exploitation rates (parasite indices) and S. solidus excretory-secretory products (SsESP) involved in immune manipulation. In our experimental infections, sticklebacks from Iceland were more resistant to S. solidus infection compared to Spanish and German sticklebacks. Higher resistance of Icelandic sticklebacks seemed to depend on adaptive immunity, whereas sticklebacks of German origin, which were more heavily afflicted by S. solidus, showed elevated activity of innate immune traits. German S. solidus were less successful in infecting and exploiting allopatric hosts compared to their Icelandic and Spanish conspecifics. Nevertheless, exclusively SsESP from German S. solidus triggered significant in vitro responses of leukocytes from naïve sticklebacks. Interestingly, parasite indices were almost identical across the sympatric combinations. Differences in host resistance and parasite virulence between the origins were most evident in allopatric combinations and were consistent within origin; i.e. Icelandic sticklebacks were more resistant and their S. solidus were more virulent in all allopatric combinations, whereas German sticklebacks were less resistant and their parasites less virulent. Despite such differences between origins, the degree of host exploitation was almost identical in the sympatric host-parasite combinations, suggesting that the local evolutionary arms race of hosts and parasites resulted in an optimal virulence, maximising parasite fitness while avoiding host overexploitation.

Abstract
During summer 2016, all the conditions for local mosquito-borne transmission of Zika virus (ZIKV) are met in mainland France: a competent vector, Aedes albopictus, a large number of travellers returning from ZIKV-affected areas, and an immunologically naive population. From 1 January to 15 July 2016, 625 persons with evidence of recent ZIKV infection were reported in mainland France. We describe the surveillance system in place and control measures implemented to reduce the risk of infection.

Abstract
Many helminth parasites have evolved strategies to evade the immune response of their hosts, which includes immunomodulation. Prostaglandin E2 (PGE2) is one of the best-described immunomodulators in mammalian helminth parasite infections. We hypothesized that also in teleost fish anti-helminthic immune responses are regulated via PGE2. We used a model system consisting of the tapeworm Schistocephalus solidus and its host, the three-spined stickleback (Gasterosteus aculeatus), to investigate in vitro effects of PGE2 on head kidney leucocytes (HKL) derived from sticklebacks that were experimentally infected with S. solidus. PGE2 was tested alone or in combination with either S. solidus antigens or bacterial lipopolysaccharides (LPS). After in vitro culture, cell viability and changes in leucocyte subpopulations (granulocytes to lymphocytes ratios) were monitored by flow cytometry and HKL were tested for their capacity to produce reactive oxygen species (ROS) with a chemiluminescence assay. In short term (2 h) HKL cultures PGE2 did not change the total numbers of live HKL, but the production of ROS decreased significantly with high (0.1 μmol L(-1)) PGE2 concentrations. In long-term (96 h) cultures high PGE2 concentrations induced a sharp decrease of leucocytes viability, while low (0.1 pmol L(-1)) and intermediate (0.1 nmol L(-1)) concentrations of PGE2 caused elevated leucocyte viability compared to controls. This coincided with reduced ROS production in cultures with high PGE2 and elevated ROS production in cultures with low PGE2. Granulocyte to lymphocyte ratios increased with high PGE2 concentrations alone and in combination with S. solidus antigens and LPS, most prominently with HKL from S. solidus infected sticklebacks. The present study supports the hypothesis that PGE2 might be an immunomodulator in tapeworm-fish parasite-host interactions.

Abstract
Helminth parasites of teleost fish have evolved strategies to evade and manipulate the immune responses of their hosts. Responsiveness of fish host immunity to helminth antigens may therefore vary depending on the degree of host-parasite counter-adaptation. Generalist parasites, infective for a number of host species, might be unable to adapt optimally to the immune system of a certain host species, while specialist parasites might display high levels of adaptation to a particular host species. The degree of adaptations may further differ between sympatric and allopatric host-parasite combinations. Here, we test these hypotheses by in vitro exposure of head kidney leukocytes from three-spined sticklebacks (Gasterosteus aculeatus) to antigens from parasites with a broad fish host range (Diplostomum pseudospathaceum, Triaenophorus nodulosus), a specific fish parasite of cyprinids (Ligula intestinalis) and parasites highly specific only to a single fish species as second intermediate host (Schistocephalus pungitii, which does not infect G. aculeatus, and Schistocephalus solidus, infecting G. aculeatus). In vitro responses of stickleback leukocytes to S. solidus antigens from six European populations, with S. solidus prevalence from <1% to 66% were tested in a fully crossed experimental design. Leukocyte cultures were analysed by means of flow cytometry and a chemiluminescence assay to quantify respiratory burst activity. We detected decreasing magnitudes of in vitro responses to antigens from generalist to specialist parasites and among specialists, from parasites that do not infect G. aculeatus to a G. aculeatus-infecting species. Generalist parasites seem to maintain their ability to infect different host species at the costs of relatively higher immunogenicity compared to specialist parasites. In a comparison of sympatric and allopatric combinations of stickleback leukocytes and antigens from S. solidus, magnitudes of in vitro responses were dependent on the prevalence of the parasite in the population of origin, rather than on sympatry. Antigens from Norwegian (prevalence 30-50%) and Spanish (40-66%) S. solidus induced generally higher in vitro responses compared to S. solidus from two German (<1%) populations. Likewise, leukocytes from stickleback populations with a high S. solidus prevalence showed higher in vitro responses to S. solidus antigens compared to populations with low S. solidus prevalence. This suggests a rather low degree of local adaptation in S. solidus populations, which might be due to high gene flow among populations because of their extremely mobile final hosts, fish-eating birds.

Abstract
Helminth parasites have evolved remarkable strategies to manipulate the immune system of their hosts. During infections of three-spined stickleback (Gasterosteus aculeatus) with the cestode Schistocephalus solidus prominent immunological changes occur, presumably due to manipulative activity of the parasite. We hypothesise that excretory/secretory products of the parasite are involved in the manipulation of the stickleback's immune system and that this may depend on the individual parasite and its origin. We therefore produced S. solidus conditioned cell culture media (SSCM) with parasites from different origins (Norway, Spain and Germany) and exposed head kidney leukocytes (HKL) from un-infected sticklebacks in cell cultures to SSCM. After in vitro culture, HKL were subjected to differential cell counts (granulocytes/lymphocytes) by means of flow cytometry. Leukocyte sub-populations were analysed for cell viability and changes in cell morphology. The respiratory burst activity was measured with a luminescence assay. Exposure of HKL to SSCM induced an up-regulation of respiratory burst activity after already 1 h, which was still elevated at 24 h, but which was in some cases significantly down-regulated after 96 h. Respiratory burst was positively correlated with the number of live granulocytes in the culture, suggesting that the respiratory burst activity was changed by SSCM effects on granulocyte viability. After 1 h and 24 h of HKL culture, no lymphocyte responses to SSCM were detectable, but after 96 h lymphocyte viability was significantly decreased with SSCM from Spanish S. solidus. In these cultures, residual lymphocytes increased in size, suggesting that cell death and activation might have occurred in parallel. The highest respiratory burst activity was induced by SSCM from Spanish parasites, in particular when they were grown in sympatric sticklebacks. The in vitro HKL responses to SSCM depended on the individual parasite and its population of origin, suggesting that in vivo, S. solidus excretory products are regulated individually, possibly to balance the interplay of each individual host-parasite pair.

Abstract
Abstract
Background: Breast cancer is the most common type of cancer among Brazilian women with almost 50.000 new cases per year. There are few data regarding the clinical presentation, treatment and specially outcome of this population. Brazilian health system is composed by Public institutions (Pu); Private centers (Pr) and some institutions that assist both Public and Private patients (PuPr).
Material and Methods: We collected data from 17 cancer centers distributed throughout Brazil among Pu; Pr and PuPr centers. We've analyzed data from 1-clinical characteristics, 2- pathologic characteristics and 3-type of treatment received among 2435 patients from May 2008 to May 2009.
Results: Mean age at diagnosis was 53 years, with about 30% below age 50. Most of the cases were Invasive Ductal Cancer (83%). Stage 0 was seen in 3.2%, Stage I in 21,8%, Stage II in 46,6%, Stage 3 in 24,6% and Stage IV in 3,9 %. Clinical Stage III + IV was seen in 18,5% of the Pu institutions, only 3,7% of the Pr ones and about 6,2% among those PuPr. Hormone receptors were positive in 55%. Her-2 was overexpressed in 27,3% of the patients, and triple negative were seen in 11,6%. Most of the patients were submitted to surgery (92,9%). In Pu institutions only 36% of the patients were submitted to Breast Conserving Surgery (BCS) and in the Pr institutions 49,4% of the patients were submitted to BCS and in the PuPr 47%. Breast reconstruction was made in 15,8% and did not differ between Pu and Pr institutions. Sentinel node biopsy was done in 30,6% of the patients (26,8% of the patients from the Pr institutions and 26,8% of the Pu ones and 33% among PuPr). Neoadjuvant treatment was done in 21,5% of the patients (Pu=27,2%; Pr=13,9% and PuPr 13,2%). Most of this neoadjuvant treatment was chemotherapy (93,8%) and only 4,3% was hormonetherapy (HT). 30% of the patients received AC, 41% A+taxane and 18,9% FAC/FEC. Besides we have almost 30% of Her-2 overexpressed only 1,1% of the patients received trastuzumab in the neoadjuvant setting. Tamoxifen was used in 48,3% when neoadjuvant HT was done, and aromatase inhibitor (AI) was used in 34,5%. Most of the patients received any kind of adjuvant treatment (89,2%). Chemotherapy was done in 76,6% and hormonetherapy in 69,8%. When chemotherapy was used the preference regiment was FAC/FEC (27,3%), followed by CMF (17,5%) and AC (11,9%). Trastuzumab was use in only 5,8% of the patients (Pu=6,8%, Pr=18,3% and PuPr 3% among all patients that received chemotherapy). In the adjuvant setting, Tamoxifen (TAM) was prescribed in 69,8% of the cases (Pu=87,6%, Pr=79,6% and PuPr 78,8%), AI in 8,2% (Pu=5,9%, Pr=9,3% and PuPr 13,8%), and sequential TAM/AI in 6,6% (Pu=6,1%, Pr=8,3% and PuPr 6,4%). About 17% of the patients had metastasis.
Conclusions: There are important differences between the public and private institutions in Brazil, the patients from the Pu institutions were five times more likely to be diagnosed in stage III or IV, they usually receive neoadjuvant treatment, and when surgery was done, most of them were treated with radical procedures. Besides the overexpression of Her-2 (30%) a minority of the patients received treatment with trastuzumab even for the Private centers (high cost for a developing country).

Abstract
7645 Background: In patients (pts) with relapsed NSCLC, erlotinib 150 mg/d significantly prolonged survival, delayed symptom progression, and improved quality of life versus placebo (Shepherd et al, N Engl J Med 2005;353:123–32). TRUST is an open label, non- randomized trial initiated to provide erlotinib access to pts with advanced NSCLC. Methods: Eligible pts had stage IIIb/IV NSCLC, and had failed or were unsuitable for chemotherapy. Erlotinib (150 mg/d p.o.) was given until disease progression or unacceptable toxicity. Pts were monitored monthly. Results: In November 2006, data were available for 5,015 pts (ITT population) from 51 countries. Median age was 63y (range 19–95). Pt characteristics (%) were: male/female 62/38; Caucasian/Oriental/other 76/19/5; non-smoker/ex- or current-smoker 28/71 (no data 1); ECOG PS 0/1/2/3 21/53/20/6; adenocarcinoma/squamous cell/other 53/25/21; stage IIIb/IV 22/78; erlotinib 1st/2nd/3rd-line/other 14/48/37/1. Safety data were available for 4,423 pts, 55% of whom had at least one adverse event (AE). Only 5% had one or more erlotinib- related serious AEs, the most common being gastrointestinal (GI) disorders (86 pts; 63 grade [gr] 3/4). 6% of pts discontinued treatment due to erlotinib-related AEs: GI disorders in 96 pts (54 gr 3/4), skin disorders in 92 (50 gr 3/4). Unexpected erlotinib-related AEs occurred in 10% of pts (4% gr 1, 3% gr 2, 3% gr 3/4). As expected, rash was observed in 70% of pts, with the majority (84%) being of gr 1/2. 80% pts received >4 weeks of erlotinib. Among 4,405 pts, only 14% had dose reductions, mainly due to rash (83%) and diarrhea (21%). Similar safety results were seen for 2nd-line pts only. Efficacy for all and 2nd-line pts will be presented. Conclusions: These results, achieved through routine clinical use of erlotinib in unselected pts with advanced NSCLC, confirm the favorable tolerability profile seen with erlotinib in selected patients in the clinical trial setting.

Abstract
Some of the competitions of the Olympic Winter Games in Torino, 10 to 26 February 2006, were organised in France near the city of Briançon, in the department of Hautes-Alpes.
An epidemiologic surveillance system was set up by the local health authorities. The goals were to detect in a timely fashion any phenomenon which could justify prevention or sanitary control action, and to guide interventions in the case of outbreak or environmental pollution.
Surveillance was implemented from 30 January to15 March 2006 in the Briançon area.
Mortality was tracked using by analysing the number and cause of deaths.
A sentinel network of general practitioners was set up and reported the frequency of acute gastroenteritis, influenza-like illness and measles. Medical laboratories provided data about the analyses they undertook. Hospital emergency department and emergency ambulance service activities were followed up. Statutory notification diseases and toxic effects of carbon monoxide surveillances were reinforced.
Analysed data were transmitted daily to the health authorities. A French/English report was sent weekly to all participants.
The participation rate was close to 100%, and data transmission deadlines were respected. No adverse health event was identified.
The strong acceptability of this surveillance system comes from its good understanding by the participants. This surveillance, structured around routine and ad-hoc systems, allowed the establishment of the foundations of a network to be used in case of outbreak or environmental pollution.
