Traditional approaches to health professional education are being challenged by increased clinical demands and decreased available time. Web-based e-learning tools offer a convenient and effective method of delivering education, particularly across multiple health care facilities. The effectiveness of this model for health professional education needs to be explored in context. The study aimed to (1) determine health professionals' experience and knowledge of clinical use of vancomycin, an antibiotic used for treatment of serious infections caused by methicillin-resistant Staphylococcus aureus (MRSA) and (2) describe the design and implementation of a Web-based e-learning tool created to improve knowledge in this area. We conducted a study on the design and implementation of a video-enhanced, Web-based e-learning tool between April 2014 and January 2016. A Web-based survey was developed to determine prior experience and knowledge of vancomycin use among nurses, doctors, and pharmacists. The Vancomycin Interactive (VI) involved a series of video clips interspersed with question and answer scenarios, where a correct response allowed for progression. Dramatic tension and humor were used as tools to engage users. Health professionals' knowledge of clinical vancomycin use was obtained from website data; qualitative participant feedback was also collected. From the 577 knowledge survey responses, pharmacists (n=70) answered the greatest number of questions correctly (median score 4/5), followed by doctors (n=271; 3/5) and nurses (n=236; 2/5; P<.001). Survey questions on target trough concentration (75.0%, 433/577) and rate of administration (64.9%, 375/577) were answered most correctly, followed by timing of first level (49%, 283/577), maintenance dose (41.9%, 242/577), and loading dose (38.0%, 219/577). Self-reported \"very\" and \"reasonably\" experienced health professionals were also more likely to achieve correct responses. The VI was completed by 163 participants during the study period. The rate of correctly answered VI questions on first attempt was 65% for nurses (n=63), 68% for doctors (n=86), and 82% for pharmacists (n=14; P<.001), reflecting a similar pattern to the knowledge survey. Knowledge gaps were identified for loading dose (39.2% correct on first attempt; 64/163), timing of first trough level (50.3%, 82/163), and subsequent trough levels (47.9%, 78/163). Of the 163 participants, we received qualitative user feedback from 51 participants following completion of the VI. Feedback was predominantly positive with themes of \"entertaining,\" \"engaging,\" and \"fun\" identified; however, there were some technical issues identified relating to accessibility from different operating systems and browsers. A novel Web-based e-learning tool was successfully developed combining game design principles and humor to improve user engagement. Knowledge gaps were identified that allowed for targeting of future education strategies. The VI provides an innovative model for delivering Web-based education to busy health professionals in different locations.

Abstract Objective: To examine the accuracy of a new version of the Sheffield table designed to aid decisions on lipids screening and detect thresholds for risk of coronary heart disease needed to implement current guidelines for primary prevention of cardiovascular disease. Design: Comparison of decisions made on the basis of the table with absolute risk of coronary heart disease or cardiovascular disease calculated by the Framingham risk function. The decisions related to statin treatment when coronary risk is ≥years; aspirin treatment when the risk is ≥ 15% over 10 years; and the treatment of mild hypertension when the cardiovascular risk is≥0% over 10 years. Setting: The table is designed for use in general practice. Subjects: Random sample of 1000 people aged 35–64 years from the 1995 Scottish health survey. Main outcome measures: Sensitivity, specificity, and positive and negative predictive values of the table. Results: 13% of people had a coronary risk of ≥15%, and 2.2% a risk of ≥30%, over 10 years. 22% had mild hypertension (systolic blood pressure 140–159 mm Hg). The table indicated lipids screening for everyone with a coronary risk of ≥15% over 10 years, for 95% of people with a ratio of total cholesterol to high density lipoprotein cholesterol of ≥8.0, but for <50% with a coronary risk of <5% over 10 years. Sensitivity and specificity were 97% and 95% respectively for a coronary risk of ≥15% over 10 years; 82% and 99% for a coronary risk of ≥30% over 10 years; and 88% and 90% for a cardiovascular risk of ≥20% over 10 years in mild hypertension. Conclusion: The table identifies all high risk people for lipids screening, reduces screening of low risk people by more than half, and ensures that treatments are prescribed appropriately to those at high risk, while avoiding inappropriate treatment of people at low risk.

In this trial of a recombinant VZV glycoprotein E subunit vaccine with the adjuvant AS01 B , the risk of herpes zoster and postherpetic neuralgia is shown to be significantly lower in association with the vaccine than with placebo among persons 70 years of age or older. Herpes zoster, or shingles, results from the reactivation of latent varicella–zoster virus (VZV) and typically manifests as a vesicular, painful dermatomal rash. 1 , 2 The most common complication of herpes zoster, postherpetic neuralgia, manifests as chronic neuropathic pain that can greatly limit daily activities. 1 , 3 – 6 The overall incidence of herpes zoster is 2.0 to 4.6 cases per 1000 person-years but increases with age to 10.0 to 12.8 per 1000 person-years among persons 80 years of age or older. 7 – 10 Similarly, the incidence of postherpetic neuralgia also increases with age. 10 – 13 Antiviral therapy can reduce the duration of herpes zoster rash . . .

Internet-based learning for health professional education is increasing. It offers advantages over traditional learning approaches, as it enables learning to be completed at a time convenient to the user and improves access where facilities are geographically disparate. We developed and implemented the Vancomycin Interactive (VI) e-learning tool to improve knowledge on the clinical use of the antibiotic vancomycin, which is commonly used for treatment of infections caused by methicillin-resistant Staphylococcus aureus (MRSA). The aims of this study were to evaluate the effect of the VI e-learning tool on (1) survey knowledge scores and (2) clinical use of vancomycin among health professionals. We conducted a comparative pre-post intervention study across the 14 hospitals of two health districts in New South Wales, Australia. A knowledge survey was completed by nurses, doctors, and pharmacists before and after release of a Web-based e-learning tool. Survey scores were compared with those obtained following traditional education in the form of an email intervention. Survey questions related to dosing, administration, and monitoring of vancomycin. Outcome measures were survey knowledge scores among the three health professional groups, vancomycin plasma trough levels, and vancomycin approvals recorded on a computerized clinical decision support system. Survey response rates were low at 26.87% (577/2147) preintervention and 8.24% (177/2147) postintervention. The VI was associated with an increase in knowledge scores (maximum score=5) among nurses (median 2, IQR 1-2 to median 2, IQR 1-3; P<.001), but not among other professional groups. The comparator email intervention was associated with an increase in knowledge scores among doctors (median 3, IQR 2-4 to median 4, IQR 2-4; P=.04). Participants who referred to Web-based resources while completing the e-learning tool achieved higher overall scores than those who did not (P<.001). The e-learning tool was not shown to be significantly more effective than the comparator email in the clinical use of vancomycin, as measured by plasma levels within the therapeutic range. The e-learning tool was associated with improved knowledge scores among nurses, whereas the comparator email was associated with improved scores among doctors. This implies that different strategies may be required for optimizing the effectiveness of education among different health professional groups. Low survey response rates limited conclusions regarding the tool's effectiveness. Improvements to design and evaluation methodology may increase the likelihood of a demonstrable effect from e-learning tools in the future.

•These data provide a comprehensive overview of the safety profile of RZV from two pivotal phase 3 studies.•A favourable benefit-risk profile of RZV was demonstrated.•This overview will help healthcare practitioners in making informed clinical decisions. The ZOE-50 (NCT01165177) and ZOE-70 (NCT01165229) phase 3 clinical trials showed that the adjuvanted recombinant zoster vaccine (RZV) was ≥90% efficacious in preventing herpes zoster in adults. Here we present a comprehensive overview of the safety data from these studies. Adults aged ≥50 (ZOE-50) and ≥70 (ZOE-70) years were randomly vaccinated with RZV or placebo. Safety analyses were performed on the pooled total vaccinated cohort, consisting of participants receiving at least one dose of RZV or placebo. Solicited and unsolicited adverse events (AEs) were collected for 7 and 30 days after each vaccination, respectively. Serious AEs (SAEs) were collected from the first vaccination until 12 months post-last dose. Fatal AEs, vaccination-related SAEs, and potential immune-mediated diseases (pIMDs) were collected during the entire study period. Safety was evaluated in 14,645 RZV and 14,660 placebo recipients. More RZV than placebo recipients reported unsolicited AEs (50.5% versus 32.0%); the difference was driven by transient injection site and solicited systemic reactions that were generally seen in the first week post-vaccination. The occurrence of overall SAEs (RZV: 10.1%; Placebo: 10.4%), fatal AEs (RZV: 4.3%; Placebo: 4.6%), and pIMDs (RZV: 1.2%; Placebo: 1.4%) was balanced between groups. The occurrence of possible exacerbations of pIMDs was rare and similar between groups. Overall, except for the expected local and systemic symptoms, the safety results were comparable between the RZV and Placebo groups irrespective of participant age, gender, or race. No safety concerns arose, supporting the favorable benefit-risk profile of RZV.

•RZV efficacy against HZ or PHN was similar in women and men.•In ≥50-year-olds, efficacy against HZ was 95.7–97.2% across geographic regions.•In ≥70-year-olds, efficacy against HZ and PHN was 86.8–100% across geographic regions.•No major efficacy differences observed against HZ and PHN by geographic ancestry/ethnicity.•RZV efficacy against HZ and PHN in these subsets was consistent with the overall ZOE-50/70 population. Herpes zoster (HZ) risk appears to vary by sex and geographic ancestry/ethnicity. In 2 randomized clinical trials, participants received 2 doses of adjuvanted recombinant zoster vaccine (RZV) or placebo intramuscularly, 2 months apart. In this post-hoc analysis, we investigate efficacy of RZV against HZ and postherpetic neuralgia (PHN) by sex, geographic region, and geographic ancestry/ethnicity in ≥50-year-olds (ZOE-50: NCT01165177) and ≥70-year-olds (pooled data from ZOE-50 and ZOE-70: NCT01165229). Vaccine efficacy against HZ or PHN was similar in women and men. Across geographic regions, efficacy against HZ ranged between 95.7 and 97.2% in ≥50-year-olds, and between 87.3% and 95.1% in ≥70-year-olds; efficacy against PHN ranged between 86.8 and 100% in ≥70-year-olds. Across ancestral/ethnic groups, efficacy ranged between 88.1 and 100% against HZ and between 65.9 and 100% against PHN in ≥70-year-olds. While the ZOE-50/70 studies were not powered or pre-designed for these post-hoc analyses, RZV appears efficacious against HZ and PHN irrespective of sex, region, or geographic ancestry/ethnicity.

The prostanoid, PGE2, is known to inhibit human lung mast cell activity. The aim of the present study was to characterize the EP receptor that mediates this effect. PGE2 (pEC50, 5.8±0.1) inhibited the IgE‐mediated release of histamine from mast cells in a concentration‐dependent manner. Alternative EP receptor agonists were studied. The EP2‐selective agonist, butaprost (pEC50, 5.2±0.2), was an effective inhibitor of mediator release whereas the EP1/EP3 receptor agonist, sulprostone, and the EP1‐selective agonist, 17‐phenyl‐trinor‐PGE2, were ineffective. The DP agonist PGD2, the FP agonist PGF2α, the IP agonist iloprost and the TP agonist U‐46619 were ineffective inhibitors of IgE‐mediated histamine release from mast cells. PGE2 induced a concentration‐dependent increase in intracellular cAMP levels in mast cells. The effects of the EP1/EP2 receptor antagonist, AH6809, and the EP4 receptor antagonist, AH23848, on the PGE2‐mediated inhibition of histamine release were determined. AH6809 (pKB, 5.6±0.1) caused a modest rightward shift in the PGE2 concentration–response curve, whereas AH23848 was ineffective. Long‐term (24 h) incubation of mast cells with either PGE2 or butaprost (EP2 agonist), but not sulprostone (EP1/EP3 agonist), caused a significant reduction in the subsequent ability of PGE2 to inhibit histamine release. Collectively, these data suggest that PGE2 mediates effects on human lung mast cells by interacting with EP2 receptors. British Journal of Pharmacology (2006) 147, 707–713. doi:10.1038/sj.bjp.0706664
