In a study of 280 patients who underwent transcatheter aortic valve replacement (TAVI), researchers investigated the 3-year prognostic impact of frailty evaluated by the Kihon checklist (KCL), a survey originally developed to identify elderly individuals who were at risk of requiring support within the Japanese long-term care insurance system. Results showed that the estimated 3-year mortality rate was significantly higher in individuals who ranked high on the KCL, showcasing the checklist as a simple tool to be used alongside other surgical risk scores, in identifying patients who are too frail to benefit from TAVI

Poor sleep kills people through medical illnesses, traffic accidents (impaired concentration and decision making), and suicides (relating to mood disorders). Since joining The Education University of Hong Kong in 2015, Dr Esther Lau Yuet-ying, Associate Professor at the Department of Psychology, has been conducting a long-term research programme that sheds light on the underlying mechanisms of sleep deprivation and its negative effect on emotions, cognition and daily functioning. The findings have been disseminated via public media and workshops to education and government bodies and have led to changes in community attitudes and school policy. They have also resulted in the establishment and strengthening of clinical and consultation support for sleep health in universities and government departments.

Scientists are turning to genomics to better understand the epidemiology of malaria and to inform control and elimination interventions and strategies. In the Lake Victoria region of Kenya, malaria burden remains very high despite more than a decade of intense control activities. A team of researchers from Osaka City University, Nagasaki University, London School of Hygiene and Tropical Medicine, and Mount Kenya University generated whole Plasmodium falciparum genome sequences from the lake region. Their analyses revealed that malaria parasites from this region appear distinct from other parasites from East Africa, while frequencies of known drug resistance markers were similar to those in other East African parasite populations. Their findings will help to develop improved surveillance tools to determine parasite transmission routes and aid clinical disease management.

Researchers reveal correlation between ribotype (RT) strains of Cutibacterium acnes, which are found in human skin, and the lifespan of the nematode Caenorhabditis elegans. Strains RT4 and 8, which are associated with acne in human skin, shortened the lifespan of the nematode, while RT6, which are predominantly found in healthy human skin, did not. Also, it was found that the healthy skin-related RT6 strain of C. acnes improved C. elegans resistance to the pathogenic organism Staphylococcus aureus.
