RESUMEN
AIM: If not conducted correctly, nursing handover can threaten patient safety, and so nursing students require good handover education. This study evaluated a handover education programme based on situated learning theory in a clinical practicum. METHODS: A quasi-experimental design and convenience sampling technique were used. The participants (fourth-grade nursing students recruited from a college in the C province of South Korea) were assigned to an intervention group (n = 38) or a control group (n = 39). A handover education programme that included lectures, expert observations, role playing, peer learning and reflection was received by the intervention group. The control group attended lectures and observed handovers. The handover skills of all participants were tested 2 weeks before and on the last day of the clinical practicum. Handover performance ability, handover clinical judgement ability and handover self-efficacy were outcome variables. RESULTS: Significant improvements in handover performance ability, handover clinical judgement ability and handover self-efficacy were observed in the intervention group compared with the control group. CONCLUSION: The significance of this study lies in the development and application of a programme based on situated learning theory for handover education. Application of theory-based handover education in clinical practicums is recommended to improve the handover capabilities of nursing students.

PURPOSE: The purpose of this study was to investigate the effects of home-and-workplace combined exercise on physical function, depression, and work-related disability in patients with ankylosing spondylitis. METHODS: This study adopted a non-randomized quasi-experimental design. Fifty-two patients were recruited: home-and-workplace combined exercise (n = 17), home exercise (n = 18), and control group (n = 17). RESULTS: The home-and-workplace combined exercise group showed improvement in spinal mobility and pulmonary function and significantly lower absenteeism and overwork impact than the home-exercise group and control group. The home-and-workplace combined exercise and home exercise groups showed a higher level of activity improvement than the control group. CONCLUSION: home-and-workplace combined exercise can be recommended to patients with ankylosing spondylitis to enhance their physical function, including spinal mobility and pulmonary function, and reduce work-related disability.

The use of inactivated Japanese encephalitis (JE) vaccines has been ongoing in East Asia for 40 years. A mouse immunogenicity assay followed by a Plaque Reduction Neutralization (PRN) Test (PRNTest) is currently recommended for each lot release of the vaccine by many national authorities. We developed an alternative in vitro ELISA to determine the E antigen content of the Japanese encephalitis virus to observe the 3Rs strategy. A collaborative study for replacing the in vivo potency assay for the Japanese encephalitis vaccine with the in vitro ELISA assay was confirmed comparability between these two methods. The study demonstrated that an in vitro assay could perform faster and was more convenient than the established in vivo PRNTest. Moreover, this assay had better precision and reproducibility compared with the conventional in vivo assay. Additionally, the content of antigen determined using the in vitro ELISA correlated well with the potency of the in vivo assay. Furthermore, this method allowed discrimination between individual lots. Thus, we propose a progressive switch from the in vivo assay to the in vitro ELISA for JE vaccine quality control.

Aluminum (Al) components in vaccines are known to act as adsorbents that interfere with accurate protein quantification by the Lowry method. Therefore, certain modifications based on the characteristics and compositions of the vaccine are required for determination of protein contents. We investigated the effects of an additional centrifugal separation and found that protein contents were overestimated by up to 238% without centrifugation through a collaborative study performed with hepatitis B vaccines containing Al. However, addition of a centrifugation step yielded protein concentrations that were similar to the actual values, with small coefficients of variation (CVs). Proficiency testing performed in 11 laboratories showed that four laboratories did not have satisfactory results for vaccines containing aluminum hydroxide, although all laboratories were proficient in protein analysis when samples did not contain aluminum hydroxide. Incomplete resuspension of aluminum hydroxide solution with alkaline copper solution was the major cause of insufficient proficiency in these laboratories.
