Abstract
PURPOSE The objective of this study was to analyze the intra- and interobserver variability of this measurement according to a strict methodology and on a representative sample of the general population, as well as to identify the possible difficulties of measurement in case of patellar or trochlear dysplasia. METHODS This observational study involved radiographic analysis by three independent observers of a total of 50 patients who had a loaded patellofemoral X-ray taken with the knee flexed to 45°. An initial reading was taken to measure the angle of the trochlear sulcus, the Merchant angle, and to classify the knees according to a possible trochlear dysplasia and/or patellar dysplasia according to Wiberg. A second measurement was then performed to analyze intraobserver agreement. Interobserver agreement was measured on all radiographic measurements (n = 100). RESULTS The Merchant patellofemoral congruence angle showed good intraobserver concordance ranging from 0.925 (95% CI 0.868-0.957) to 0.942 (95% CI 0.898-0.967), as well as interobserver concordance ranging from 0.795 (95% CI 0.695-0.862) to 0.914 (95% CI 0.872-0.942). Poor results were found in terms of interobserver concordance on the measurement of the Merchant angle in case of stage 3 Wiberg patella ranging from 0.282 (95% CI -0.920 to 0.731) to 0.611 (95% CI 0.226-0.892). CONCLUSION Congruence angle is one of most commonly used measurements for patellar tracking. However, the convexity of the patellar surface makes it difficult to identify the patellar apex on its intraarticular facet, making the measurement of the Merchant congruence angle unreliable and not very reproducible in cases of stage 3 Wiberg patella. Registration N°IRB 2021/139.

Abstract
BACKGROUND This phase 2 observer-blind, randomized, multicenter, dose-ranging study evaluated immunogenicity and safety of different formulations of an AS03-adjuvanted H5N1 influenza vaccine in children 6-35 months of age. METHODS One hundred eighty-five children randomized into 5 groups [1.9 µg hemagglutinin (HA)/AS03B, 0.9 µg HA/AS03C, 1.9 µg HA/AS03C, 3.75 µg HA/AS03C or 3.75 µg HA/AS03D] were to receive 2 doses administered 21 days apart (primary vaccination). AS03 was classified by amount of DL-α-tocopherol, with AS03B the highest amount. One year later, all subjects were to receive unadjuvanted 3.75 µg HA as antigen challenge. Immunogenicity was assessed 21 days after primary vaccination (day 42) and 7 days after antigen challenge (day 392). Immunogenicity-fever index, based on hemagglutination inhibition and microneutralization antibody titers at day 42 and fever 7 days after each vaccination, was used to guide the selection of an acceptable formulation. RESULTS After primary vaccination, formulations elicited strong homologous immune responses with all subjects' hemagglutination inhibition titers ≥1:40 post-vaccination. Immunogenicity-fever index based on hemagglutination inhibition and microneutralization assays showed that 1.9 µg HA/AS03B ranked the highest. Antibody levels persisted >4 times above baseline 12 months after primary vaccination with all formulations (day 385). Antibodies increased >4-fold after antigen challenge (day 392/day 385) with 1.9 µg HA/AS03B, 0.9 µg HA/AS03C and 1.9 µg HA/AS03C formulations. Overall per subject, the incidence of fever ranged from 28.6% (3.75 µg HA/AS03D) to 60.5% (1.9 µg HA/AS03B). CONCLUSIONS All formulations were highly immunogenic and demonstrated acceptable safety profiles, with the 1.9 µg HA/AS03B providing the most favorable balance of immunogenicity versus reactogenicity for use in children 6-35 months of age.

Abstract
Immunocompromised (IC) persons are at increased risk for herpes zoster (HZ) and its complications, mainly due to impairment of cell-mediated immunity (CMI). The adjuvanted recombinant zoster vaccine (RZV) demonstrated efficacy against HZ in autologous hematopoietic stem cell transplant (auto-HSCT) recipients and hematologic malignancy (HM) patients. We review immune responses to RZV in 5 adult IC populations, 4 of which were receiving multiple, concomitant immunosuppressive medications: auto-HSCT and renal transplant recipients, HM and solid tumor patients, and human immunodeficiency virus-infected adults. Although administered in most cases when immunosuppression was near its maximum, including concomitantly with chemotherapy cycles, RZV induced robust and persistent humoral and, more importantly, CMI responses in all 5 IC populations. Based on the overall clinical data generated in older adults and IC individuals, RZV is expected to provide benefit in a broad adult population at risk for HZ.

Abstract
Background Immunocompromised (IC) populations are at increased risk of developing herpes zoster (HZ) due to disease- and/or therapy-induced immunosuppression. The adjuvanted recombinant zoster vaccine (RZV) has demonstrated 68.2% efficacy in preventing HZ in autologous hematopoietic stem cell transplant (HSCT) recipients and 87.2% efficacy in a post-hoc analysis in hematologic malignancy (HM) patients ≥ 18 years of age (YOA). Here we present the immunogenicity of RZV in representative IC populations. Methods Our analysis includes five phase I/II/III clinical trials conducted worldwide between 2010–2017 (Table 1) in IC populations (autologous HSCT, human immunodeficiency virus [HIV]-infected, HM, solid tumor [ST] on chemotherapy and renal transplant [RT] patients) ≥ 18 YOA. Anti-glycoprotein E (gE) antibody geometric mean concentrations (GMCs) and gE-specific CD4 T cell frequencies were descriptively evaluated by age group (18–49 YOA and ≥ 50 YOA) and overall at 1 month (M) and 12M post-last RZV dose. Table 1. Clinical studies with immunocompromised populations included in our analysis ![]()
Results The according-to-protocol cohorts for immunogenicity from the included trials are presented in Table 1. At 1M post-last RZV dose, anti-gE GMCs and median CD4 T-cell frequencies increased in all IC populations compared to pre-vaccination and persisted above baseline up to 12M post-last RZV dose (Figures 1 and 2). No meaningful differences were seen between age groups in terms of humoral (except a slight trend for stronger responses in the 18–49 YOA RT and HM patients compared to their corresponding ≥ 50 YOA group) and gE-specific CD4 T-cell responses in any of the IC populations. Figure 1. Humoral immune responses to RZV in immunocompromised populations (adapted ATP cohort for humoral immunogenicity) ![]()
Figure 2. Cell-mediated immune responses to RZV in immunocompromised populations (adapted ATP cohort for cell-mediated immunogenicity) ![]()
Conclusion RZV induced robust and persistent humoral and cell-mediated immune (CMI) responses that lasted up to at least 12M post-last vaccination in all evaluated IC populations. Humoral responses in the IC populations were robust although not as strong as in the non-IC adults ≥ 50 YOA. CMI responses were mostly similar across IC populations and adults ≥ 50 YOA, with a potent response occurring even in ST patients undergoing chemotherapy. This data shows that RZV is immunogenic even in severely IC adults.

Abstract
OBJECTIVE We aimed to evaluate the level of knowledge of Middle East respiratory syndrome coronavirus (MERS-CoV) among Hajj pilgrims before and after an education health programme during international vaccine consultations in France. STUDY DESIGN A cross-sectional study was performed in the consultation for travel medicine and international vaccination in Reims University Hospital between July 2014 and October 2015. METHODS Consecutive adults (>18 years old) who attended for pre-Hajj meningococcal vaccination were eligible to complete an anonymous questionnaire with closed answers to evaluate their level of knowledge about MERS-CoV. To evaluate the effectiveness of the information given during the consultation, the same questionnaire was completed by the Hajj pilgrim before and after the consultation, where the information about MERS-CoV was provided. RESULTS Among 82 Hajj pilgrim adults enrolled in the study, less than 25% were aware of the routes of transmission, symptoms and preventive behaviours to adopt abroad or in case of fever. Pilgrims had a higher rate of correct responses on each question at the time they completed the second questionnaire, as compared with the first, with 11 of 13 questions answered significantly better after delivery of educational information about MERS-CoV. However, although the rate of correct answers to the questions about routes of transmission, symptoms, preventive behaviours to adopt in case of fever and time delay between return and potential MERS-CoV occurrence increased significantly after receiving the information, the rates remained below 50%. CONCLUSION Information given during travel consultations significantly increases the general level of knowledge, but not enough to achieve epidemic control.

Abstract
BACKGROUND GSK has modified the licensed monovalent bulk manufacturing process for its split-virion inactivated quadrivalent influenza vaccine (IIV4) to harmonize the process among different strains, resulting in an increased number of finished vaccine doses, while compensating for the change from inactivated trivalent influenza vaccine (IIV3) to IIV4. To confirm the manufacturing changes do not alter the profile of the vaccine, a clinical trial was conducted to compare IIV4 made by the currently licensed process with a vaccine made by the new (investigational) process (IIV4-I). The main objectives were to compare the reactogenicity and safety of IIV4-I versus IIV4 in all age groups, and to demonstrate the non-inferiority of the hemagglutination-inhibition (HI) antibody responses based on the geometric mean titer ratio of IIV4-I versus IIV4 in children. METHODS The Phase III, randomized, double-blind, multinational study included three cohorts: adults (18-49 years; N = 120), children (3-17 years; N = 821), and infants (6-35 months; N = 940). Eligible subjects in each cohort were randomized 1:1 to receive IIV4-I or IIV4. Both vaccines contained 15 μg of hemagglutinin antigen for each of the four seasonal virus strains. Adults and vaccine-primed children received one dose of vaccine, and vaccine-unprimed children received two doses of vaccine 28 days apart. All children aged ≥9 years were considered to be vaccine-primed and received one dose of vaccine. RESULTS The primary immunogenicity objective of the study was met in demonstrating immunogenic non-inferiority of IIV4-I versus IIV4 in children. The IIV4-I was immunogenic against all four vaccine strains in each age cohort. The reactogenicity and safety profile of IIV4-I was similar to IIV4 in each age cohort, and there was no increase in the relative risk of fever (≥38 °C) with IIV4-I versus IIV4 within the 7-day post-vaccination period in infants (1.06; 95% Confidence Interval: 0.75, 1.50; p = 0.786). CONCLUSIONS The study demonstrated that in adults, children, and infants, the IIV4-I made using an investigational manufacturing process was immunogenic with a reactogenicity and safety profile that was similar to licensed IIV4. These results support that the investigational process used to manufacture IIV4-I is suitable to replace the current licensed process.

Abstract
INTRODUCTION We compared co-administration versus separate administration of an inactivated quadrivalent influenza vaccine (IIV4) with a 23-valent pneumococcal polysaccharide vaccine (PPV23) in adults at high risk of complications of influenza and pneumococcal infection. METHODS This phase III, placebo-controlled, observer-blind trial (NCT02218697) was conducted in France and Belgium during the 2014-2015 influenza season. Adults≥50years of age meeting their country's vaccination recommendations were randomized 1:1 to co-administration or separate administration. Immunogenicity was assessed by hemagglutination inhibition (HI) titers for IIV4 and 22F-inhibition ELISA for PPV23. Co-primary objectives were to demonstrate non-inferiority of co-administration versus separate administration in terms of geometric mean titer (GMT) ratio for each influenza strain in the IIV4 and geometric mean concentration (GMC) ratio for six pneumococcal serotypes (1, 3, 4, 7F, 14, 19A) in the PPV23 in the per-protocol cohort (N=334). RESULTS The study met its co-primary objectives, with the upper limit of the 95% confidence interval of the GMT and GMC ratios (separate administration over co-administration) being ≤2.0 for all four antigens of the IIV4 and the six pre-selected serotypes of the PPV23, respectively. Immunogenicity of the IIV4 and PPV23 was similar regardless of administration schedule. In a post hoc analysis pooling participants ≥60years of age from the co-administration and separate administration groups, IIV4 immunogenicity was similar in higher risk adults with comorbidities (diabetes; respiratory, heart, kidney, liver, or neurological diseases; morbid obesity) versus those without. Both vaccines had an acceptable safety and reactogenicity profile; pain was the most common symptom, occurring more often with co-administration than separate administration. CONCLUSION The IIV4 and PPV23 can be co-administered without reducing antibody responses reflecting protection against influenza or pneumococcal disease. Co-administration of PPV23 at the annual influenza vaccination visit may improve uptake. Comorbidities had no impact on IIV4 immunogenicity, supporting its value in older adults with chronic medical conditions. Clinical Trial Registry Number: NCT02218697.

Abstract
BACKGROUND Avian influenza A H9N2 strains have pandemic potential. METHODS In this randomized, observer-blind study (ClinicalTrials.gov: NCT01659086), 420 healthy adults, 18-64years of age, received 1 of 10 H9N2 inactivated split-virus vaccination regimens (30 participants per group), or saline placebo (120 participants). H9N2 groups received 2 doses (days 0, 21) of 15µg hemagglutinin (HA) without adjuvant, or 1.9µgHA+AS03A, 1.9µgHA+AS03B, 3.75µgHA+AS03A, or 3.75µgHA+AS03B; followed by the same H9N2 formulation or placebo (day 182). AS03 is an adjuvant system containing α-tocopherol (AS03A: 11.86mg; AS03B: 5.93mg) and squalene in an oil-in-water emulsion. Immunogenicity (hemagglutination inhibition [HI] and microneutralization assays) and safety were assessed up to day 546. RESULTS All adjuvanted formulations exceeded regulatory immunogenicity criteria at days 21 and 42 (HI assay), with seroprotection and seroconversion rates of ≥94.9% and ≥89.8% at day 21, and 100% and ≥98.1% at day 42. Immunogenicity criteria were also met for unadjuvanted vaccine, with lower geometric mean titers. In groups administered a third vaccine dose (day 182), an anamnestic immune response was elicited with robust increases in HI and microneutralization titers. Injection site pain was reported more frequently with adjuvanted vaccines. No vaccine-related serious adverse events were observed. CONCLUSIONS All H9N2 vaccine formulations were immunogenic with a clinically acceptable safety profile; adjuvanted formulations were 4-8 times dose-sparing (3.75-1.9vs 15µgHA). TRIAL REGISTRATION Registered on ClinicalTrials.gov: NCT01659086.

Abstract
OBJECTIVE We aimed to evaluate factors associated with knowledge of antibiotics and drug resistance. METHODS A questionnaire was handed out by 14 family physicians to their patients between December 20, 2014 and April 20, 2015 in Rethel (North-East of France). We conducted a cross-sectional study using a logistical regression model to assess factors associated with antibiotic knowledge. Three criteria were used to assess that knowledge. RESULTS Overall, 293 questionnaires were analysed; 48% of patients had received antibiotics in the previous 12 months. Only 44% and 26% gave a correct answer for the statements "Antibiotics are effective against bacteria and ineffective against viruses" and "Antibiotic resistance decreases if the antibiotic use decreases", respectively. Characteristics such as female sex, age>30 years, high level of education, high professional categories, and having received antibiotic information by the media were associated with high level of knowledge about antibiotics and/or antibiotic resistance. In contrast, having received antibiotic information from family physicians was not associated with good knowledge. CONCLUSION Although media awareness campaigns had an independent impact on a higher public knowledge of antibiotics, the overall public knowledge remains low. It would be necessary to strengthen antibiotic campaigns with clearer information on the relation between the excessive use of antibiotics and the increased risk of antibiotic resistance. Family physicians should be more involved to improve antibiotic knowledge among target groups such as men, young patients, and people from a poor social and cultural background.

Abstract
Frailty is an increasingly common geriatric condition that results in an increased risk of adverse health outcomes such as falls. The most widely-used means of detecting frailty is the Fried phenotype, which includes several objective measures such as grip strength and gait velocity. One method of screening for falls is to measure balance, which can be done by a range of techniques including the assessment of the Centre of Pressure (CoP) during a balance assessment. The Balance Quality Tester (BQT) is a device based on a commercial bathroom scale that can evaluate balance quality. The BQT provides instantaneously the position of the CoP (stabilogram) in both anteroposterior (AP) and mediolateral (ML) directions and can estimate the vertical ground reaction force. The purpose of this study was to examine the relationship between balance quality assessment and physical frailty. Balance quality was compared to physical frailty in 186 older subjects. Rising rate (RR) was slower and trajectory velocity (TV) was higher in subjects classified as frail for both grip strength and gait velocity (p<;0.05). Balance assessment could be used in conjunction with functional tests of grip strength and gait velocity as a means of screening for frailty.

Abstract
Background. Cell-culture-derived (CC) influenza vaccine production methods could provide benefits over classical embryonated-egg technology, including a higher production capacity and the faster creation of a supply that meets demand. Methods. A CC-inactivated split-virus influenza A/Indonesia/5/2005(H5N1) vaccine derived from the EB66 cell line (hereafter, “CC-H5N1”) was investigated in a phase 1 randomized, blinded study. Healthy adults (n = 521) received 2 vaccine doses (days 0 and 21) of either investigational CC-H5N1 vaccine (1.9 µg or 3.75 µg of hemagglutinin antigen [HA] with the AS03 adjuvant system or 15 µg of plain HA), embryonated-egg-derived vaccines (3.75 µg of HA with AS03 or 15 µg of plain HA), or placebo. Assessment of the adjuvant effect and immunogenicity was performed using Center for Biologics Evaluation and Research acceptability criteria 21 days after dose 2. Safety was assessed until month 12. Results. AS03-adjuvanted CC-H5N1 elicited a homologous hemagglutination inhibition antibody response that satisfied immunogenicity criteria 21 days after dose 2 and persisted at month 12. Adjuvant effect and immune response against a drift-variant strain were demonstrated. No vaccine-related serious adverse events were reported. The immunogenicity and safety of the CC-H5N1 formulation containing 3.75 µg of HA and AS03 appeared to be similar to those for the licensed egg-derived AS03-adjuvanted control vaccine. Conclusions. The feasibility of the EB66 cell line to produce an immunogenic influenza vaccine with acceptable safety profile was demonstrated. Antigen sparing was achieved through combination with AS03 adjuvant. This CC-H5N1 might contribute to the rapid access of vaccine in the event of an influenza A(H5N1) pandemic. Clinical Trials Registration NCT01236040.

Abstract
Clinical trials have shown that AS03-adjuvanted H5N1 and A(H1N1)pdm09 vaccines are highly immunogenic, although with an increased reactogenicity profile relative to non-adjuvanted vaccines in terms of the incidence of common injection site and systemic adverse events (AEs). We evaluated pooled safety data from 22,521 adults who had received an AS03-adjuvanted H5N1 or A(H1N1)pdm09 influenza or control vaccine with the purpose to identify medically-attended AEs (MAEs), including subsets of serious AEs (SAEs), potentially immune-mediated diseases (pIMDs), and AEs of special interest (AESI), and to explore a potential association of these AEs with the administration of an AS03-adjuvanted influenza vaccine. For participants who had received an AS03-adjuvanted vaccine, the relative risks (RRs) for experiencing a MAE or a SAE compared to control group (participants who had received a non-adjuvanted vaccine or saline placebo) were 1.0 (95% confidence interval [CI]: 0.9; 1.1) and 1.1 (95% CI: 0.9; 1.4), respectively. The overall RRs for experiencing an AESI or a pIMD (AS03-adjuvanted vaccine/control) were 1.2 (95% CI: 0.9; 1.6) and 1.7 (95% CI: 0.8; 3.8), respectively. Thirty-8 participants in the AS03-adjuvanted vaccine group had a pIMD reported after vaccine administration, yielding an incidence rate (IR) of 351.9 (95% CI: 249.1; 483.1) per 100,000 person-years. The estimated IRs in the AS03-adjuvanted vaccine group were greater than the literature reported rates for: facial paresis/VIIth nerve paralysis, celiac disease, thrombocytopenia and ulcerative colitis. These results do not support an association between AS03-adjuvanted H5N1 and A(H1N1)pdm09 vaccines and the AEs collected in the trials included in the analysis.

Abstract
BACKGROUND This phase 2/3, randomized, placebo-controlled, observer-blinded study assessed the immunogenicity, reactogenicity, and safety of an inactivated, split-virion H5N1 influenza vaccine (A/Indonesia/5/2005) in children aged 6 months through 17 years. METHODS Children received 2 influenza vaccine doses 21 days apart, each containing 1.9 µg of hemagglutinin and AS03B adjuvant (5.93 mg of α-tocopherol). The randomization ratio was 8:3 for vaccine to placebo, with equal allocation between 3 age strata (6-35 months, 3-8 years, and 9-17 years). Immunogenicity against the vaccine strain was assessed 21 days after the first and second vaccine doses for all vaccinees, at day 182 for half, and at day 385 for the remaining half. Reactogenicity after each dose and safety up to 1 year after vaccination were evaluated. RESULTS Within each age stratum, the lower limit of the 98.3% confidence interval for the day 42 seroprotection rate was ≥70%, thus fulfilling the US and European licensure criteria. The immune responses elicited by vaccine persisted well above baseline levels for 1 year. The vaccine was more reactogenic than placebo, but no major safety concerns were identified. CONCLUSIONS AS03B-adjuvanted H5N1 influenza vaccine was immunogenic and showed an acceptable safety profile in all age groups studied. Clinical Trials Registration: NCT01310413.

Abstract
Background. Protecting young children from pandemic influenza should also reduce transmission
to susceptible adults, including pregnant women. Methods. An open study assessed immunogenicity and reactogenicity of a heterologous booster
dose of A/turkey/Turkey/1/2005(H5N1)-AS03B (AS03B is an Adjuvant
System containing α-tocopherol and squalene in an oil-in-water emulsion [5.93 mg
tocopherol]) in infants and children aged 6 to < 36 months that was given 6 months
following 2-dose primary vaccination with A/Indonesia/05/2005(H5N1)-AS03B.
Vaccines contained 1.9 µg of hemagglutinin antigen and AS03B. Hemagglutinin
inhibition (HI) responses, microneutralization titers, and antineuraminidase antibody
levels were assessed for 6 months following the booster vaccination. Results. For each age stratum (defined on the basis of the subject's age at first
vaccination as 6 to < 12 months, 12 to < 24 months, and 24 to < 36 months) and
overall (n = 113), European influenza vaccine licensure criteria were fulfilled for
responses to A/turkey/Turkey/1/2005(H5N1) 10 days following the booster vaccination. Local
pain and fever increased with consecutive doses. Anamnestic immune responses were
demonstrated for HI, neutralizing, and antineuraminidase antibodies against
vaccine-homologous/heterologous strains. Antibody responses to
vaccine-homologous/heterologous strains persisted in all children 6 months following the
booster vaccination. Conclusions. Prevaccination of young children with a clade 2 strain influenza A(H5N1)
AS03-adjuvanted vaccine followed by heterologous booster vaccination boosted immune
responses to the homologous strain and a related clade, with persistence for at least 6
months. The results support a prime-boost vaccination approach in young children for
pandemic influenza preparedness. Clinical Trials Registration. NCT01323946.

Abstract
BACKGROUND/PURPOSE This study evaluated the immune response elicited by two formulations of an AS03(A)-adjuvanted H5N1 A/Indonesia/05/2005 prepandemic influenza vaccine, developed using manufacturing processes with or without thiomersal. In addition, it also evaluated compliance to the Centre for Biologics Evaluation and Research and Committee for Medicinal Products for Human Use (CHMP) immunogenicity guidance criteria for pandemic influenza vaccines in adults. METHODS This phase III, observer-blind, randomized study (NCT00812981) enrolled 320 subjects aged 18-60 years into two groups to receive, 21 days apart, two doses of the formulation manufactured using either the thiomersal-containing process (Group TC) or the thiomersal-free process (Group TF). Blood samples collected before vaccination, 21 days after the second vaccine dose, and 6 months following the first vaccine dose (Days 0, 42, and 180) were analysed using a hemagglutination inhibition (HI) assay. Safety assessments were made for the entire study period. RESULTS Twenty-one days after the second dose of vaccine, both groups met the CHMP criteria for vaccine-homologous HI response (seroprotection rates/seroconversion rates ≥ 98.7%, seroconversion factor ≥ 121.9) and also for a heterologous HI response against the A/Vietnam/1194/2004 strain (seroprotection rates/seroconversion rates ≥ 81.3%, seroconversion factor ≥ 10.8). Six months after the first dose of vaccine, a marked persistence of the vaccine-homologous HI response was observed that still met one or more CHMP criteria. Pain at the injection site (Group TF 95%, Group TC 91.8%) and myalgia (Group TF 68.8%, Group TC 63.5%) were the most frequently recorded solicited symptoms. Overall, both formulations had a clinically acceptable safety profile. CONCLUSION Administration of two doses of the AS03(A)-adjuvanted H5N1 prepandemic influenza vaccine was found to be highly immunogenic in adults with a clinically acceptable safety profile. The ability to confer cross-clade protective immunity makes it a suitable option for mitigation of the morbidity and mortality of outbreaks and pandemics due to H5N1 and drifted strains.

Abstract
OBJECTIVE The present study (NCT00449670) in Asian subjects (18-60 years) evaluated the manufacturing consistency of four formulations of 3.75 mg AS03(A)-adjuvanted H5N1 influenza vaccine, in terms of post-immunization Hemagglutination Inhibition (HI) titers against the A/Vietnam/1194/2004 and A/Indonesia/05/2005 strains. The immunogenicity and safety of the vaccine in the Thai population are reported herein. MATERIAL AND METHOD Subjects were randomized (2:2:2:2.:1:1) between four vaccine groups and two control groups to receive two doses of either the AS03(A)-adjuvanted or non-adjuvanted H5N1 vaccine formulations, 21 days apart. Sera were assayed for HI antibody titers against the two strains. RESULTS After the second dose of AS03(A)-adjuvanted vaccine, 94.2% subjects in the H5N1-AS03(A) groups seroconverted and 94.9% subjects were seroprotected against the A/Vietnam/1194/2004 strain. Cross-clade immune response against the A/Indonesia/05/2005 strain was observed. All vaccine formulations had an acceptable safety profile. CONCLUSION This antigen-sparing AS03(A)-adjuvanted influenza vaccine could be a suitable candidate for combating and mitigating future influenza pandemics.

Abstract
The aim of this study was to evaluate the usefulness of the screening questions in the French version of the Dementia Quality of Life (DQoL) questionnaire. To assess the psychometric properties of the French DQoL, 155 patients with mild-to-moderate dementia were recruited. Here, we compared the psychometric properties of the instrument between patients who passed the screening test (n = 109) and the whole study population (n = 155). The French DQoL version showed a good test-retest reliability at a 2-week interval (0.95 ≤ intraclass correlation coefficients ≤ 1.0), and an average internal consistency (0.58 ≤ Cronbach's α ≤ 0.87) for the 2 study groups. Significant differences were observed in the 2 groups for 4 dimensions of the DQoL regarding dementia severity (Cornell scale), and for 3 dimensions evaluating depression (MMSE). Convergent validity with the Duke Health Profile revealed many significant correlations between dimensions not only in the 109 patients, but also in the whole study population. Our study demonstrated that patients who failed the screening procedure nonetheless seemed to be able to answer the DQoL questionnaire, the whole study group showing acceptable psychometric properties.

Abstract
BACKGROUND Dementia is a serious, chronic, and costly public health problem. Prior studies have described dementia as increasing length of hospital stay, but so far no explanations have been proposed. METHODS To identify early markers for prolonged hospital stay in demented elderly inpatients, 178 community-dwelling or institutionalized subjects aged 75+, hospitalized through an emergency department in 9 teaching hospitals in France, were analyzed. Prolonged hospital stays were defined according a limit adjusted for Diagnosis Related Group. All patients underwent a comprehensive geriatric assessment at admission. Logistic regression multifactorial mixed model was performed. Center effect was considered as a random effect. RESULTS Of the 178 stays, 52 were prolonged. Most concerned community-dwelling patients (86%). Multifactor analysis demonstrated that demographic variables had no influence on the length of stay, while diagnosis of delirium (OR 2.31; 95% CI 1.77 - 2.91), walking difficulties (OR 1.94; 95% CI 1.62 - 2.43) and report by the informal caregiver of moderate or severe burden (OR 1.52; 95% CI 1.19 - 1.86) or low social quality-of-life score (OR 1.25; 95% CI 1.03 - 1.40), according to the Zarit's Burden Inventory short scale (12 items) and the Duke's Health Profile respectively, were identified as early markers for prolonged hospital stays. CONCLUSION At the time of the rising incidence of cognitive disorders, these results suggest that preventive approaches might be possible. In a hospital setting as well as in a community-dwelling population, more specific, specialized and coordinated care, using the expertise of multiple disciplines appears as a probable effective measure to limit prolonged hospital stay. Such approaches require (i) clear patient-oriented goal definition, (ii) understanding and appreciation of roles among various health care and social disciplines and, (iii) cooperation between partners in patient's management. However, the cost- and health-effectiveness of such approaches should be evaluated.

Abstract
OBJECTIVES The aim of the study was, by early identification of deleterious prognostic factors that are open to remediation, to be in a position to assign elderly patients to different mortality risk groups to improve management. DESIGN Prospective multicentre cohort. SETTING Nine French teaching hospitals. PARTICIPANTS One thousand three hundred and six (1 306) patients aged 75 and over, hospitalised after having passed through Emergency Department (ED). MEASUREMENTS Patients were assessed using Comprehensive Geriatric Assessment (CGA) tools. A Cox survival analysis was performed to identify prognostic variables for six-week mortality. Receiver Operating Characteristics analysis was used to study the discriminant power of the model. A mortality risk score is proposed to define three risk groups for six-week mortality. RESULTS Crude mortality rate after a six week follow-up was 10.6% (n=135). Prognostic factors identified were: malnutrition risk (HR=2.1; 95% CI: 1.1-3.8; p=.02), delirium (HR=1.7; 95% CI: 1.2-2.5; p=.006), and dependency: moderate dependency (HR=4.9; 95% CI: 1.5-16.5; p=.01) or severe dependency (HR=10.3; 95% CI: 3.2-33.1; p < .001). The discriminant power of the model was good: the c-statistic representing the area under the curve was 0.71 (95% IC: 0.67 - 0.75; p < .001). The six-week mortality rate increased significantly (p < .001) across the three risk groups: 1.1% (n=269; 95% CI=0.5-1.7) in the lowest risk group, 11.1% (n=854; 95% CI=9.4-12.9) in the intermediate risk group, and 22.4% (n=125; 95% CI=20.1-24.7) in the highest risk group. CONCLUSIONS A simple score has been calculated (using only three variables from the CGA) and a practical schedule proposed to characterise patients according to the degree of mortality risk. Each of these three variables (malnutrition risk, delirium, and dependency) identified as independent prognostic factors can lead to a targeted therapeutic option to prevent early mortality.

Abstract
BACKGROUND The unexpected problems at 1 of 2 US licensed manufacturers of trivalent inactivated influenza virus vaccine (TIV) in 2004 highlights the urgent need for additional vaccine sources. We evaluated a split virus TIV (Fluarix, GSK), to generate data supportive of a license application in the US. METHODS Healthy adults ages 18-64 years at four centers were randomly assigned to receive a single IM injection of Fluarix (n = 763) or placebo (n = 193) in double-blind fashion. Subjects were monitored for safety and serum hemagglutination-inhibition (HAI) titers determined before and 21 days after vaccination. RESULTS Vaccine was well tolerated, with only mild to moderate myalgias and injection site pain and redness being more common in vaccine than placebo recipients. Four-fold or greater increases in serum HAI titers were seen in 60%, 62% and 78% of vaccine recipients against the H1, H3, and B components of the vaccine, respectively, and post-vaccination titers of > 1:40 achieved in 98%, 99% and 99% of subjects, exceeding the prespecified criteria for acceptability for all three antigens. CONCLUSIONS Fluarix has a safety and immunogenicity profile like other US-licensed inactivated influenza vaccines and should be effective when used to immunize US adults. SUMMARY LINE: The results of this study were pivotal for the rapid approval of Fluarix in the US for use in adults 18 years of age or older.
