DESIGN: This was a qualitative study comprising semi-structured face-to-face interviews guided by 10 open-ended questions. Interviews were conducted until data saturation was achieved and no new ideas were formed. The interviews were audio-recorded, transcribed verbatim and analysed for themes. To derive themes, we employed directed content analysis of transcript data. Coding was completed using a combination of open, axial and selective coding.

SETTING: Four nursing homes in Singapore.

PARTICIPANTS: The study involved 17 participants (comprising 4 doctors, 4 pharmacists and 9 nurses).

RESULTS: Two key themes were identified, enablers and challenges. These were enablers and challenges faced by doctors, pharmacists and nurses towards deprescribing. The identified subthemes for enablers of deprescribing were: (1) awareness of medications that are unnecessary or could be targeted for deprescribing; (2) improving quality of life for patients with limited life expectancy; (3) improving communication between doctors, pharmacists and nurses; (4) systematic deprescribing practice and educational tools and (5) acknowledgement of possible benefits of deprescribing. The identified subthemes for challenges of deprescribing were: (1) symptoms not acknowledged as possibly drug-related; (2) lack of knowledge in patient's and family members' preferences; (3) lack of coordination between health professionals in hospitals and nursing homes and (4) limited tools for deprescribing. The development of a local guideline, mentoring nurses, case discussions, better shared decision-making and improving multidisciplinary communication, may help to support the process of deprescribing.

METHODS: We report the establishment of an immunocompetent wild type strain 129 (wt-129) mouse model, which can be cross-species infected with human EV-A71 clinical isolates via an intraperitoneal route.

RESULTS: One intriguing disease phenotype of this new model is the development of characteristic "White-Jade" patches in the muscle, which lost sporadically the normal pink color of uninfected muscle. Viral VP1 protein and massive leukocyte infiltration were detected in muscles with or without white-jades. We demonstrated further that hypoxia is a general phenomenon associated with white-jades in both immunocompetent and immunodeficient mouse models. Therefore, hypoxia appears to be a feature intrinsic to EV-A71 infection, irrespective of its host's immunogenetic background. To date, no effective treatment for EV-A71 is available. Here, using this new wt-129 mouse model, we showed that timely treatment with compound R837 (a TLR7 immune modulator) via oral or intraperitoneal routes, rescued the hypoxia, limb paralysis, and death at a high therapeutic efficacy.

METHODS: This was an observational study reviewing all confirmed ZIKV cases detected in Malaysia through the ZIKV clinical surveillance and Flavivirus laboratory surveillance between June 2015 and December 2017. All basic demographic characteristics, co-morbidities, clinical, laboratory and outcome data of the confirmed ZIKV cases were collected from the source documents.

RESULTS: Only eight out of 4043 cases tested positive for ZIKV infection during that period. The median age of infected patients was 48.6 years and majority was Chinese. Two of the subjects were pregnant. The median interval between the onset of disease and the first detection of ZIKV Ribonucleic Acid (RNA) in body fluid was 3 days. Six cases had ZIKV RNA detected in both serum and urine samples. Phylogenetic analysis suggests that isolates from the 7 cases of ZIKV infection came from two clusters, both of which were local circulating strains.
