Abstract
Bone and joint infections represent a potentially devastating complication of prosthetic orthopedic joint replacement, thus requiring both rapid and appropriate antibiotic treatment. Staphylococcus aureus is one of the most common pathogens involved in this pathology. Being able to assert its presence is the first step of efficient patient management. This monocenter study evaluated the MRSA/SA ELITe MGB assay for the molecular detection of S. aureus and methicillin-resistant S. aureus (MRSA) in bone and joint biopsy specimens and synovial fluids. This test, together with conventional techniques, including standard cultures and the 16S rRNA amplification assay, was performed on 208 successive perioperative samples collected prospectively for 1 year obtained from 129 patients. Using conventional techniques, we detected a microbial pathogen in 76 samples from 58 patients, 40 of which were identified as S. aureus. The limit of detection (LOD) of the MRSA/SA ELITe MGB assay was experimentally determined for bone and joint biopsy specimens and synovial fluids using negative samples spiked with S. aureus ATCC 43300. The sensitivities of S. aureus detection with the MRSA/SA ELITe MGB assay were 82.5% (33/40 samples) and 97.5% (39/40 samples) using the manufacturer's LOD and an experimentally determined LOD, respectively. Interestingly, using the osteoarticular specific LOD, 15 additional samples were determined to be positive for S. aureus DNA with the MRSA/SA ELITe MGB assay; in all cases, these samples were obtained from patients considered to be infected with S. aureus according to their clinical and microbiological records. The results were available within 24 h, which could help to expedite therapeutic decisions.

Abstract
The Secproch working group (for "sécurité des produits issus du corps humain") was created in 2019 within the « Haut Conseil de la santé publique » (HCSP) for addressing all the questions related to labile blood products, organs, tissues, cells (OTC) and gametes issued from human body. It is notably in charge of the management of alerts regarding arbovirus infections. These infections due to arthropod-transmitted viruses are responsible for emergence and reemergence, notably in the context of global warming. This review relates the alerts taken into consideration by the Secproch group between 2019 and 2021 following three pathologies due to Flaviviridae : dengue, West Nile virus (WNV) infection and tick-borne encephalitis (TBE). The dengue alerts have occurred in French Indies where the virus is endemic/epidemic, Reunion Island where the population was naïve until 2018 towards the virus, and the metropole where foci of autochthonous cases are observed sporadically. The WNV infection was responsible of both human and equine cases in 2019 in the South of France but with intensity much less than in 2018. At last, the TBE virus was at the origin of a cluster of about 40 cases in the Ain department following a contamination by crude non-pasteurized goat cheese. This review offers the opportunity to reevaluate the risks linked to these three viruses through blood products and organs/tissues/cells and to precise the means recommended by HCSP to secure these products.

Abstract
Introduction Bien que, par analogie aux autres coronavirus, la maladie COVID-19 induite par SARS-CoV-2 ait été initialement supposée monophasique et transitoirement immunisante, de rares publications rapportent des patients avec 2e épisode. L’objectif de cette étude est de décrire les caractéristiques cliniques, la séquence moléculaire de détection virale, et le devenir de patients présentant 2 épisodes distincts de COVID-19. Matériels et méthodes Une étude nationale multicentrique rétrospective observationnelle a recensé les patients présentant un 2e épisode aigu symptomatique de COVID-19, défini par au moins un signe clinique majeur typique, et une PCR SARS-CoV-2 positive dans les voies aériennes, après : – au moins 21 jours du début du 1er épisode ; – une phase de guérison clinique (retour à l’état antérieur, ou sortie de soins aigus sans oxygène), sans diagnostic différentiel infectieux, thromboembolique ou inflammatoire. Résultats Onze patients présentant un 2e épisode de COVID-19 après une guérison clinique médiane [étendue] de 10 [3–27] jours ont été recensés, et 2 groupes ont été individualisés. Dans le 1er, 4 soignants sans comorbidités, d’âge médian 32,5 [19–43] ans, potentiellement re-exposés au SARS-CoV- (3 dans des unités de soins COVID, 1 au domicile), ont présenté aux 2 épisodes une maladie modérée suivie en ambulatoire. Dans le 2e groupe, 7 patients comorbides (dont 2 sous chimiothérapie), d’âges médian 73 [54–91] ans, ont été hospitalisés en soins aigus à chaque épisode. Au 1er, 3 patients ont reçu des corticoïdes. Aucune réexposition au SARS-CoV-2 n’a été documentée, et 3 patients sont décédés, dont 2 de syndrome de détresse respiratoire aiguë sans autre cause que le SARS-CoV-2. Au 2e épisode, tous les scanners montraient des signes aigus de COVID-19, 4/9 PCR avaient des « cycle threshold » (CT) < 30, et 1 sur 2 cultures virales pratiquées était positive. La sérologie SARS-CoV-2 après j21 était positive pour 6 patients, et négative pour 3 (du 2e groupe). Conclusion Cette étude exploratoire confirme la possibilité de récurrences de symptômes après guérison clinique d’un premier épisode de COVID-19. La positivité des PCR aux 2e épisodes (de plusieurs gènes ou avec CT bas) et au moins une culture virale positive, sans diagnostic différentiel identifié, sont en faveur d’une origine virale à ces récurrences. Les caractéristiques des 2 groupes de patients suggèrent soit des réinfections, soit des réactivations virales. Un déficit immunitaire relatif cellulaire ou humoral (par épuisement professionnel ou immuno-senescence, ou traitements immunosuppresseurs), pourraient entraver la clairance virale ou l’efficacité immunitaire antivirale contre les réinfections à SARS-CoV-2. De plus larges études épidémiologiques, et immuno-virologiques sont nécessaires pour comprendre la fréquence et le(s) mécanisme(s) de ces récurrences.

Abstract
This article reports the observed rate of infection with severe acute respiratory syndrome coronavirus-2 in healthcare workers (HCWs) who worked on wards dedicated to care of patients with coronavirus disease 2019 (COVID-19) compared with HCWs who worked on non-COVID-19 wards. The infection rate was significantly higher among HCWs who worked on non-COVID-19 wards (odds ratio 2.3, P=0.005), illustrating the need to strengthen social distancing measures and training.

Abstract
Background Staphylococcus aureus is able to invade mammalian cells during infection and was recently observed inside nasal mucosa of healthy carriers. Objectives To determine the intracellular activity of antimicrobial compounds used for decolonization procedures using a cell model mimicking S. aureus nasal epithelium invasion. Patients and methods HaCaT cells and human nasal epithelial cells (HNECs) recovered from nasal swabs of S. aureus carriers were visualized by confocal laser scanning microscopy to detect intracellular S. aureus cells. An HaCaT cell model, mimicking S. aureus internalization observed ex vivo in HNECs, was used to assess the intracellular activity against S. aureus of 21 antimicrobial compounds used for nasal decolonization, including mupirocin and chlorhexidine. Results HaCaT cells and HNECs were found to internalize S. aureus with the same focal pattern. Most antimicrobial compounds tested on HaCaT cells were shown to have weak activity against intracellular S. aureus. Some systemic antimicrobials, including fusidic acid, clindamycin, linezolid, minocycline, ciprofloxacin, moxifloxacin, rifampicin and levofloxacin, reduced S. aureus intracellular loads by 0.43-1.66 log cfu/106 cells compared with the control (P < 0.001). By contrast, mupirocin and chlorhexidine reduced the S. aureus intracellular load by 0.19 and 0.23 log cfu/106 cells, respectively. Conclusions These data indicate that most of the antimicrobial compounds used for nasal decolonization, including mupirocin and chlorhexidine, exhibit weak activity against intracellular S. aureus using the HaCaT cell model. This work emphasizes the need to better understand the role of the S. aureus intracellular reservoir during nasal colonization in order to improve decolonization procedures.

Abstract
As a therapy or a support to other therapies, despite being largely beneficial to patients in general, transfusion it is not devoid of some risks. In a moderate number of cases, patients may manifest adverse reactions, otherwise referred to as transfusion-associated hazards (TAHs). The latest French 2016 haemovigilance report indicates that 93% of TAHs are minor (grade 1), 5.5% are moderate (grade 2) and 1.6% are severe (grade 3), with only five deaths (grade 4) being attributed to transfusion with relative certainty (imputability of level [or grade] 1 to 3). Health-care providers need to be well aware of the benefits and potential risks (to best evaluate and discuss the benefit-risk ratio), how to prevent TAHs, the overall costs and the availability of alternative therapeutic options. In high-income countries, most blood establishments (BEs) and hospital blood banks (HBBs) have developed tools for reporting and analysing at least severe transfusion reactions. With nearly two decades of haemovigilance, transfusion reaction databases should be quite informative, though there are four main caveats that prevent it from being fully efficient: (ai) reporting is mainly declarative and is thus barely exhaustive even in countries where it is mandatory by law; (aii) it is often difficult to differentiate between the different complications related to transfusion, diseases, comorbidities and other types of therapies in patients suffering from debilitating conditions; (aiii) there is a lack of consistency in the definitions used to describe and report some transfusion reactions, their severity and their likelihood of being related to transfusion; and (aiv) it is difficult to assess the imputability of a particular BC given to a patient who has previously received many BCs over a relatively short period of time. When compiling all available information published so far, it appears that TAHs can be analysed using different approaches: (bi) their pathophysiological nature; (bii) their severity; (biii) the onset scheme; (biv) a quality assessment (preventable or non-preventable); (bv) their impact on ongoing therapy. Moreover, TAHs can be reported either in a non-integrative or in an integrative way; in the latter case, presentation may also differ when issued by a blood establishment or a treating ward. At some point, a recapitulative document would be useful to gain a better understanding of TAHs in order to decrease their occurrence and severity and allow decision makers to determine action plans: this is what this review attempts to make. This review attempts to merge the different aspects, with a focus on the hospital side, i.e., how the most frequent TAHs can be avoided or mitigated.

Abstract
OBJECTIVE To estimate the benefits of iterative prevalence surveys in detecting trends of hospital-acquired infections (HAIs). METHODS On the basis of the French protocol for national prevalence studies, HAI data of 15 consecutive annual surveys performed at the same period by the same group of investigators was gathered in a single database to describe the trend of HAIs in a University Hospital over a 15-year period. RESULTS A total of 20,401 patients were included. Overall, the prevalence of patients presenting with at least one HAI acquired in our University Hospital was 5.1% [95% CI, 4.8-5.4%]. The prevalence of HAIs and antimicrobial drug use significantly decreased over time (P<0.01). CONCLUSION Despite limitations, repeated prevalence surveys can be a useful tool for promoting control measures to better prevent HAIs.

Abstract
OBJECTIVE We aimed to describe the management of a carbapenemase-producing Acinetobacter baumannii (CP-AB) outbreak using the Outbreak Reports and Intervention Studies of Nosocomial Infection (ORION) statement. We also aimed to evaluate the cost of the outbreak and simulate costs if a dedicated unit to manage such outbreak had been set-up. METHODS We performed a prospective epidemiological study. Multiple interventions were implemented including cohorting measures and limitation of admissions. Cost estimation was performed using administrative local data. RESULTS Five patients were colonized with CP-AB and hospitalized in the neurosurgery ward. The index case was a patient who had been previously hospitalized in Portugal. Four secondary colonized patients were further observed within the unit. The strains of A. baumannii were shown to belong to the same clone and all of them produced an OXA-23 carbapenemase. The closure of the ward associated with the discharge of the five patients in a cohorting area of the Infectious Diseases Unit with dedicated staff put a stop to the outbreak. The estimated cost of this 17-week outbreak was $474,474. If patients had been managed in a dedicated unit - including specific area for cohorting of patients and dedicated staff - at the beginning of the outbreak, the estimated cost would have been $189,046. CONCLUSION Controlling hospital outbreaks involving multidrug-resistant bacteria requires a rapid cohorting of patients. Using simulation, we highlighted cost gain when using a dedicated cohorting unit strategy for such an outbreak.

Abstract
Staphylococcus aureus nasal colonization is a well-known independent risk factor for infection caused by this bacterium. Screening and decolonization of carriers have been proven effective in reducing S. aureus infections in some populations. However, a gap remains between what has been proven effective and what is currently done. We aimed to summarize recommendations and current knowledge of S. aureus decolonization to answer the following questions: Why? For whom? How? When? And what are the perspectives?

Abstract
Group A rotavirus (RVA) is the leading cause of acute gastroenteritis in young children worldwide. A prospective surveillance network has been set up to investigate the virological and clinical features of RVA infections and to detect the emergence of potentially epidemic strains in France. From 2009 to 2014, RVA-positive stool samples were collected from 4800 children <5 years old attending the paediatric emergency units of 16 large hospitals. Rotaviruses were then genotyped by RT-PCR with regard to their outer capsid proteins VP4 and VP7. Genotyping of 4708 RVA showed that G1P[8] strains (62.2%) were predominant. The incidence of G9P[8] (11.5%), G3P[8] (10.4%) and G2P[4] (6.6%) strains varied considerably, whereas G4P[8] (2.7%) strains were circulating mostly locally. Of note, G12P[8] (1.6%) strains emerged during the seasons 2011-12 and 2012-13 with 4.1% and 3.0% prevalence, respectively. Overall, 40 possible zoonotic reassortants, such as G6 (33.3%) and G8 (15.4%) strains, were detected, and were mostly associated with P[6] (67.5%). Analysis of clinical records of 624 hospitalized children and severity scores from 282 of them showed no difference in clinical manifestations or severity in relation to the genotype. The relative stability of RVA genotypes currently co-circulating and the large predominance of P[8] type strains may ensure vaccine effectiveness in France. The surveillance will continue to monitor the emergence of new reassortants that might not respond to current vaccines, all the more so as all genotypes can cause severe infections in infants.

Abstract
Viral safety remains a major concern in transfusion of blood products. Over years, the control measures applied to blood products were made more and more sophisticated; however, the number of infectious agents, and notably of viruses, that can be transmitted by transfusion is increasing continuously. The aim of this review paper is to actualize that published in the same journal by the same authors in 2011 with more details on some of actual vs virtual viral threats that were identified recently in the field of blood transfusion. The main subjects that are covered successively concern the transmission via transfusion of hepatitis E virus, the frequency of transfusion transmitted arboviruses, transfusion at the time of the Ebola epidemics in West Africa, the debated role of Marseillevirus (giant viruses infecting amoebae and suspected to infect human blood latently), and, finally, the recent report of the identification in blood donors of a new member of the Flaviviridae family. The addition of these new viral risks to those already identified-partially controlled or not-pleads for the urgent need to move forward to considering inactivation of infectious agents in blood products.

Abstract
Plasma therapy consists in bringing to a patient in need – in general suffering a severe, resistant to current therapy, and even lethal infection – plasma or specific, fractioned, antibodies, along with other immunoglobulins and possibly healing factors that can be obtained from immunized blood donors; donors (voluntary and benevolent) can be either actively immunized individuals or convalescent persons. Plasma therapy has been used since the Spanish flu in 1917–1918, and regularly then when viral epidemics threatened vulnerable populations, the last reported occurrence being the 2013–2015 Ebola virus outbreak in West Africa. The precise action mechanism of plasma therapy is not fully delineated as it may function beyond purified, neutralizing antibodies.

Abstract
Mobile phones (MPs) are potential reservoirs of nosocomial bacteria, but few data are available concerning viruses. We aimed to evaluate the presence of virus RNA from epidemic viruses including metapneumovirus, respiratory syncytial virus, influenza viruses, rotavirus (RV) and norovirus on the MPs used by healthcare workers (HCWs) and to relate it to hygiene measures. An anonymous behavioural questionnaire about MP use at hospital was administered to the HCWs of four adult and paediatric departments of a university hospital. After sampling personal (PMP) and/or professional MPs (digital enhanced cordless telephone, DECT), virus RNAs were extracted and amplified by one-step real-time reverse transcription–quantitative PCR. The molecular results were analysed in a masked manner in relation to the behavioural survey. Questionnaires from 114 HCWs (35 senior physicians, 30 residents, 32 nurses, 27 nurses' assistants) working either in adult (n = 58) or paediatric (n = 56) departments were analysed. Medical personnel used their PMP more frequently than paramedical HCWs (33/65 vs. 10/59, p <0.001). MPs were used during care more frequently in adult wards than in paediatric ones (46/58 vs. 27/56, p <0.001). Virus RNA was detected on 42/109 (38.5%) collected MPs, with RV found on 39, respiratory syncytial virus on three and metapneumovirus on one. The presence of virus RNA was significantly associated with MPs from the paediatric HCWs (p <0.001). MPs routinely used in hospital, even during care, can host virus RNA, especially RV. Promotion of frequent hand hygiene before and after MP use, along with frequent cleaning of MPs, should be encouraged.

Abstract
BACKGROUND The NS5A protein of the hepatitis C virus has been shown to be involved in the development of hepatocellular carcinoma. OBJECTIVES In a French multicenter study, we investigated the clinical and epidemiological features of a new HCV genotype 1b strain bearing a wide insertion into the V3 domain. STUDY DESIGN We studied NS5A gene sequences in 821 French patients infected with genotype 1b HCV. RESULTS We identified an uncharacterized V3 insertion without ORF disruption in 3.05% of the HCV sequences. The insertion comprised 31 amino-acids for the majority of patients; 3 patients had 27 amino-acids insertions and 1 had a 12 amino-acids insertion. Sequence identity between the 31 amino-acids insertions and the V3 domain ranged from 48 to 96% with E-values above 4e(-5), thus illustrating sequence homology and a partial gene duplication event that to our knowledge has never been reported in HCV. Moreover we showed the presence of the duplication at the time of infection and its persistence at least during 12 years in the entire quasispecies. No association was found with extrahepatic diseases. Conversely, patients with cirrhosis were two times more likely to have HCV with this genetic characteristic (p=0.04). Moreover, its prevalence increased with liver disease severity (from 3.0% in patients without cirrhosis to 9.4% in patients with both cirrhosis and HCC, p for trend=0.045). CONCLUSIONS We identified a duplicated V3 domain in the HCV-1b NS5A protein for the first time. The duplication may be associated with unfavorable evolution of liver disease including a possible involvement in liver carcinogenesis.

Abstract
Typing of human enterovirus (EV) remains a major goal for diagnostic and epidemiological purposes. Whereas sequencing of the VP1 coding region is the reference standard for EV typing, a method relying on sequencing of the VP2 coding region has been proposed as an alternative; however, this has been validated only on cell culture supernatants. To avoid the selection of cultivable strains and to quicken the identification step, a new semi-nested PCR method targeting the VP2 region was developed by use of the CODEHOP strategy. After validation of the method on reference and clinical strains, a total of 352 clinical specimens found to be positive for EV RNA (138 with the GeneXpert EV kit and 214 with the Enterovirus R-gene kit) during a 3-year period (2010-2012) were analysed prospectively for VP2 genotyping. Overall, 204 (58%) specimens were typeable. A higher proportion of throat swab/stool specimens than of cerebrospinal fluid (CSF) specimens was found to be typeable (94 of 142 (66.2%) vs. 83 of 169 (49.1%), respectively, p <0.01 by the chi-square test). Moreover, the median Ct value obtained was lower for typeable specimens than for untypeable specimens (32.20 vs. 33.01, p <0.05, and 25.96 vs. 31.74, p <0.001, for the GeneXpert and R-gene tests, respectively, by the Mann-Whitney-Wilcoxon test). These results suggest that, in cases of EV meningitis, a peripheral specimen (i.e. throat swab or stool) that is susceptible to exhibiting a higher viral load should be used in preference to CSF for identifying the causative EV genotype by use of the VP2 typing method without cell culture isolation.

Abstract
The novel SPF10 real-time PCR assay allows the simultaneous amplification and detection of the HPV target. That way, LiPA analysis of the HPV-negative samples can be avoided, reducing workload and cost. This study aims to evaluate the performance of the SPF10 real-time PCR in combination with the LiPA assay for HPV detection and typing in cervical samples. Thirty-nine cervical samples were subjected to the SPF10 conventional PCR in combination with the LiPA assay. Subsequently, the SPF10 real-time PCR was performed to enable the comparison between the SPF10 conventional and the real-time PCR results. In case of discrepancy, the samples were subjected to the CLART HPV2 assay. As a result, 27 out of 39 samples were identified as HPV-positive by the SPF10 real-time PCR and were genotyped further by the LiPA assay. Twenty samples (74.1%) showed an absolute agreement between the conventional and real-time SPF10 PCR (concordant), three (11.1%) displayed additional or fewer types (compatible), two (7.4%) did not show any similarity between both assays (discordant) and the remaining two (7.4%) were LiPA-negative. The two assays showed an excellent strength of agreement for individual (κ=0.932) and multiple genotype detection (κ=0.834). In conclusion, the two SPF10 PCR methods are comparable. Therefore, the SPF10 real-time PCR with subsequent LiPA could be used for the detection and genotyping of HPV in cervical samples.

Abstract
OBJECTIVES We surveyed the vaccination status of family physicians (FP) in the Loire district (France) in 2010. SUBJECTS AND METHODS A self-administered questionnaire was proposed to a panel of 460 FP; 288 (64%) answered. RESULTS The vaccination coverage for Diphtheria-Tetanus-Polio in the previous 10 years, BCG, pertussis, seasonal influenza, A/H1N1 2009 influenza, and hepatitis B was 81, 74, 59, 73, 65, and 87% respectively. Sixty-four percent of FP reported they were vaccinated against measles and 49% against chicken pox; 76% were aware of vaccination recommendations for healthcare professionals but 41% wanted more information on the subject. The younger physicians were better vaccinated for Diphtheria-Tetanus-Polio, measles, hepatitis B, and influenza according to a multivariate analysis. CONCLUSIONS The vaccinations of FP (knowledge, practice) must be improved, especially by yearly updates, continuous medical education, and medical follow-up of healthcare professionals.

Abstract
BACKGROUND Rotavirus (RV) is the main infectious agent of severe acute gastroenteritis (AGE) in infants and children under 5 years. Given the recent availability of new vaccines, it is important to accurately assess the incidence of rotavirus gastroenteritis (GERV) and their medical and epidemiological consequences. METHODS This work is the French part of study program called SPRIK, a multicenter, prospective, observational study conducted from October 2005 to May 2007 to estimate the annual incidence of GERV within children under 5 years visiting a general practitioner or pediatrician. It presents data collected by 41 general practitioners and 36 paediatricians located throughout the French metropolitan territory. A stool sample was taken for every child. Rotavirus presence was sought by the physician using a rapid immunochromatographic test. French results are presented in this article. RESULTS A total of 1648 GEA episodes corresponding to 1463 eligible patients were included in the study mainly from December to May (peak in February-March). The incidence rate of GERV leading to consultations in general practice was 1357 cases per 100,000 patient-years (PY) (1.36%), with a 95% confidence interval of [1345-1368]. The peak incidence occurs before 2 years. GERV accounted for 21% of all GEA cases seen by paediatricians and general practitioners. Patients with GERV were younger (14.1 ± 10.8 versus 18.4 ± 13.9 months for other GEA, P<0.0001) and had more severe clinical symptoms: presence of fever (32.6% versus 20.0%, P<0.0001), behavioural symptoms (45.6% versus 20.8%, P<0.0001) and dehydration (48.7% versus 21.2%, P<0.0001). GERV episodes were considered severe in 79.7% of cases, using the Vesikari scale. More than 86% patients received oral rehydration during the episode and 13 patients (5.8%) were hospitalized. Nearly 80% GERV episodes were considered severe using the Vesikari scale. Main genotypes were G1P[8] rotavirus (44%) and G9P[8] rotavirus (35%) types. CONCLUSION The incidence rate reported in this study is close to results of previous studies done in Europe. The frequency and severity relative to GERV support vaccination in very young children to reduce the burden associated with this pathology.

Abstract
The signal transducer and activator of transcription 3 (STAT3) transcription factor pathway plays an important role in many biological phenomena. STAT3 transcription is triggered by cytokine-associated signals. Here, we use isolated human B cells to analyse the role of STAT3 in interleukin (IL)-10 induced terminal B cell differentiation and in immunoglobulin (Ig)A production as a characteristic readout of IL-10 signalling. We identified optimal conditions for inducing in-vitro IgA production by purified blood naive B cells using IL-10 and soluble CD40L. We show that soluble CD40L consistently induces the phosphorylation of nuclear factor (NF)-κB p65 but not of STAT3, while IL-10 induces the phosphorylation of STAT3 but not of NF-κB p65. Interestingly, while soluble CD40L and IL-10 were synergistic in driving the terminal maturation of B cells into IgA-producing plasma cells, they did not co-operate earlier in the pathway with regard to the transcription factors NF-κB p65 or STAT3. Blocking either NF-κB p65 or STAT3 profoundly altered the production of IgA and mRNA for activation-induced cytidine deaminase (AID), an enzyme strictly necessary for Ig heavy chain recombination. Finally, the STAT3 pathway was directly activated by IL-10, while IL-6, the main cytokine otherwise known for activating the STAT3 pathway, did not appear to be involved in IL-10-induced-STAT3 activation. Our results suggest that STAT3 and NF-κB pathways co-operate in IgA production, with soluble CD40L rapidly activating the NF-κB pathway, probably rendering STAT3 probably more reactive to IL-10 signalling. This novel role for STAT3 in B cell development reveals a potential therapeutic or vaccine target for eliciting IgA humoral responses at mucosal interfaces.

Abstract
BACKGROUND The risk of hepatitis C virus (HCV) transmission during assisted reproductive techniques (ARTs) is still disputed and no report concerning its prospective evaluation is available. METHODS The aim of this 4-year follow-up multicentre study that enrolled 86 HCV-serodiscordant couples was to determine whether a sperm-processing method was able to reduce levels of HCV in semen and the risk of HCV transmission to the newborn. All the men were chronically infected by HCV and 10 of them by human immunodeficiency virus. A total of 181 seminal plasmas and 153 sperm fractions were tested for the presence of HCV RNA. RESULTS HCV RNA tested positive in 20.4% of the seminal samples. All of the 153 final sperm fractions tested negative for HCV. The detection of HCV RNA in semen was significantly correlated with a high viral load in blood (P < 0.05). The presence of HCV RNA in seminal plasma impaired neither semen parameters nor ART issue. From the 58 couples enrolled effectively in an ART programme, 24 pregnancies and 28 newborns were obtained. All of them tested negative for HCV RNA in blood. CONCLUSION These results emphasize the safety of the semen-processing method. The negligible risk of transmitting HCV reduces the value of the systematic analysis of HCV RNA in seminal fractions prior to ART. Since use of this analytical procedure involves the freezing of semen, its avoidance would result in an increase in sperm quality and reduce the need to perform intracytoplasmic sperm injection techniques.

Abstract
We report 32 cases of acute encephalitis consecutively hospitalized in one hospital, from January 1991 to December 2002. The causative agent was identified in 26 cases (81%). The main associated viruses were varicella-zoster (10 children; 31%), Herpes simplex (6 children; 19%), and enteroviruses (4 children; 13%). At the acute phase, the most relevant biological findings were electroencephalogram results and CSF analysis. The initial encephalic imaging was primarily helpful to exclude other acute neurological diseases whereas long-term imaging was a prognostic factor for necrotizing encephalitis. The microbiological diagnosis required several days or weeks to be determined. It did not influence the initial management. In addition to the 6 cases of herpetic encephalitis, 19 children (78% altogether) were then treated by acyclovir before a definitive diagnosis was made. Twenty-two children (69%) had a favorable outcome, 2 (6%) had moderate sequels, 2 (6%) had important ones, and 5 (16%) had major ones. One (3%) child died. The outcome was highly dependant on the causative agent and the mechanism of encephalitis. This series gives information on the epidemiology of encephalitis in children in our region over a period of 12 years.

Abstract
This study evaluated a multidisciplinary strategy to decrease the rate of invasive pulmonary aspergillosis (IPA) among adult patients hospitalised in two haematology wards in a single 560-bed building at the University Hospital of Saint-Etienne. Upgrading of the air filtration system and construction of an air-lock chamber at the entrance to the unit were completed during 1994. In 1995, specific hygienic measures were introduced during hospital building work, including the use of plastic barriers, watering during demolition work, reduction of pedestrian traffic in construction areas, and the wearing of high-efficiency filtration masks by immunosuppressed patients when outside the protected unit. This strategy was evaluated by a prospective survey of IPA cases between 1993 and 2001, coupled with environmental surveillance. The number and risk-level of hospital renovation projects increased between 1995 and 2001 (p < 0.01). In parallel, the rate of IPA decreased globally in the haematology unit from 0.85% (1.19/1,000 patients) in 1993 to 0.28% (0.21/1,000 patients) in 2001. The incidence of IPA decreased significantly between 1993-1996 and 1997-2001 (p 0.02, Mann-Whitney test). These results show that a multidisciplinary approach involving engineers, infection control practitioners, mycologists and clinicians enables IPA rates among patients hospitalised in haematology wards to be significantly decreased.

BACKGROUND Heterosexual human immunodeficiency virus (HIV) transmission implies the crossing of the vaginal mucosa by virions present in the semen, potentially using Langerhans cells as transporters. The recruitment of these cells in the mucosa is mediated by the chemokine macrophage inflammatory protein 3alpha (CCL20). The aim of this study was to evaluate the capacity of the semen to induce Langerhans cell recruitment via the production of CCL20 by vaginal epithelial cells. METHODS AND RESULTS Using a vaginal epithelium model based on the SiHa cell line and human seminal plasma, we demonstrated that semen enhanced the production of CCL20. This secretion was regulated by the nuclear factor-kappaB intracellular signalling pathway. Fractionation of the seminal plasma indicated that the secretion of CCL20 was stimulated by high molecular weight compounds present in semen. Migration assays demonstrated that secreted CCL20 was able to promote the recruitment of Langerhans cell precursors (LCps), which remain permissive to X4 and R5 HIV infection. CONCLUSIONS Our results demonstrate that epithelial cells respond to factors present in semen by secreting CCL20, leading to the enhancement of LCp recruitment. These data argue in favour of the implication of epithelial cells in the heterosexual transmission of HIV.
