tand clinicians' use of the pre-MET RRS tier to inform targeted strategies to optimise its design and implementation. We identified opportunities to improve guidance documents supporting the pre-MET RRS tier that may assist other health services engaged in planning or evaluating pre-MET strategies. Further research is needed to understand clinicians' use of the pre-MET RRS tier to inform targeted strategies to optimise its design and implementation. To determine the prevalence of leg ulcers, and to describe the affected patients, wounds, and treatment. Observational, cross-sectional prevalence study. An ad hoc online questionnaire was sent to all nurses attending Primary Care centres of the "Gerencia de Atención Integrada de Cuenca" (Integrated Care Management of Cuenca, Spain). Data regarding patient sociodemographic and clinical variables, lesion characteristics and the type of intervention (concerning prevention and treatment) were collected. In total, 152 professionals (response rate=98.1%) completed the questionnaire, collecting data from 131,190 inhabitants. A total of 63 patients (75.5±12.6 years old) with 75 ulcers were identified, finding an overall prevalence of 0.480‰ (CI 95% 0.375-0.614), distributed as venous ulcer 0.274‰ (n=36), diabetic foot 0.145‰ (n=19), and arterial ulcer 0.061‰ (n=8). The prevalence was similar regarding gender (0.535‰ vs. 0.426‰, respectively, p=.365), but men exhibited more diabetic foot (0.214‰ vs. 0.076‰, p=.037). In all three types of lesions prevalence increased with age, reaching 1.743‰ in 64+age group. The median of the leg ulcer duration and corrected area were 190.0±340.0 days and 5.0±13.7cm , respectively, with a recurrence rate of 74.7%. The prevalence of chronic leg ulcers was lower than that reported in other studies, although with high recurrence rates. Overall estimators from previous studies may have overestimated the prevalence, especially in regions with a high rural component.

Live-attenuated YF-17D vaccines have proven to be safe and effective in protecting travellers and populations in endemic regions against YF, despite very rare severe reactions following vaccination - YF vaccine-associated viscerotropic disease (YEL-AVD) and neurological disease (YEL-AND). We describe the generation and selection of a live-attenuated YF-17D vaccine candidate and present its preclinical profile. Initially, 24 YF-17D vaccine candidate sub-strains from the Stamaril® and YF-VAX® lineage were created through transfection of viral genomic RNA into Vero cells cultured in serum-free media to produce seed lots. The clone with the 'optimal' preclinical profile, i.e. the lowest neurovirulence, neurotropism and viscerotropism, and immunogenicity at least comparable with Stamaril and YF-VAX in relevant animal models, was selected as the vaccine candidate and taken forward for assessment at various productionsimilar to currently marketed YF vaccines.We calculated the Poisson-regression-adjusted relative risk (RR) of new influenza infection by vaccination, prior infection, and vaccination after prior infection in a large Japanese birth cohort, using data from ≤89,253 children aged 6 months to 3 years. The effectiveness of risk reduction (1 - RR) by vaccination at ages 1.5-3 years was 21%-31%. The RR of new infection after prior infection vs. no prior infection was 2.58-19.3 at age 1-3 years. An analysis of the 1 - RR data stratified by having at least one senior sibling and/or attending nursery school revealed that vaccination reduced the RR by 22%-40%. The 1 - RR of new infection was 21% in 3-year-old children who were vaccinated after prior infection. All these findings are statistically significant. The results consistently indicate that, regardless of having at least one senior sibling, attending nursery school, and/or being previously infected with influenza, infants and toddlers will benefit from influenza vaccination. Retrospective studies indicate that more cystic fibrosis (CF) pulmonary exacerbations (PEx) are treated with oral (PO) than with intravenous (IV) antimicrobials despite little knowledge of the relative effects of PO treatment on lung function recovery or long-term impacts on lung disease progression. Previous studies have suggested that PO treatment may be associated with slower lung function recovery compared with IV treatment. We used longitudinal home spirometry data from the eICE study (NCT01104402) to compare PO versus IV antimicrobial treatment responses for PEx diagnosed by home spirometry and symptom assessment. Adolescent and adult eICE participants performed home spirometry twice weekly for one year. PEx were diagnosed by a protocol-defined algorithm of change in percent predicted forced expiratory volume in 1 second (ppFEV ) and/or respiratory signs and symptoms. PO- and IV-treated PEx were grouped by initial ppFEV drop magnitude. Group ppFEV treatment responses were modeled with multivariate, repeat-measure linear regression. Of 87 qualifying PEx from 56 participants, 62 were PO-treated and 25 were IV-treated. The average drop from best ppFEV to PEx start was 11.0 [95%CI 8.5, 13.5] with similar treatment group means (p=0.72). Participants with IV-treated PEx averaged 0.72 [0.24, 1.20] ppFEV /day greater response than those treated with PO, who experienced minimal ppFEV1 recovery. Many PO-treated participants who had <10 ppFEV drop from baseline tended to worsen or show no ppFEV improvement. These results suggest that, in this cohort, PO antimicrobial treatment of CF PEx were less effective than IVs at improving ppFEV during treatment. These results suggest that, in this cohort, PO antimicrobial treatment of CF PEx were less effective than IVs at improving ppFEV1 during treatment.
