Objective: To evaluate sedentary behaviour and physical activity levels in independently mobile older adults with and without dementia living in residential aged care.
Methods: Sedentary behaviour and physical activity were measured in 37 residents of an aged care facility using an accelerometer worn during waking hours for five days.
Results: Participants with valid accelerometer data (n = 28) spent 85% of the time sedentary, and 12% in low-intensity, 2% in light-intensity and 1% in moderate-to-vigorous-intensity physical activity. Over half of sedentary time was accumulated in bouts of greater than 30 minutes. Physical activity at any level of intensity was performed in bouts of less than 10 minutes.
Conclusion: Residents were highly sedentary and inactive. In particular, the short duration of each bout of activity amongst lengthy periods of sedentary behaviour was a substantial finding. The study suggests the need to develop innovative ways of breaking up sedentary behaviour in residential aged care.

Type 2 diabetes (T2D) frequently coexists with cardiorenal complications. Therefore, a holistic approach to patient management is required, with specialists such as primary care physicians, cardiologists, endocrinologists, and nephrologists working together to provide patient care. Although glycemic control is important in the management of T2D, patients with T2D and acceptable glycemic control are still at risk from cardiovascular (CV) events such as stroke, heart attack, and heart failure (HF).

Purpose: The aim of this study was to investigate the effect of a 6-month Guolin Qigong on quality of life and serum cortisol among patients with cancer.
Methods: This study was a two-arm and non-randomized controlled trial. Forty-nine patients with cancer who were over 18 years of age and diagnosed with cancer were enrolled in this study and assigned to either the Guolin Qigong intervention group (IG, n = 26) or the usual care group (UC, n = 23) for 6 months.

Polymer based nanoformulations offer substantial prospects for efficacious chemotherapy delivery. Here, we developed a pH-responsive polymeric nanoparticle based on acidosis-triggered breakdown of boronic ester linkers. A biocompatible hyaluronic acid (HA) matrix served as a substrate for carrying a doxorubicin (DOX) prodrug which also possesses natural affinity for CD44 cells.

Objectives: To investigate whether baseline depressive symptoms impacted the effectiveness of an exercise intervention among (pre)frail older adults.
Methods: This is a subanalysis of a stepped-wedge cluster randomized trial implementing an exercise intervention, with an application of the integration of the Health Belief Model, Theory of Planned Behavior, and Health Action Process Approach, among 149 community-dwelling (pre)frail older adults. The intervention effectiveness was examined by baseline depressive symptoms (depressive symptoms ( = 40) and non-depressive symptoms ( = 109).

Discovery of cancer immunogenic chemotherapeutics represents an emerging, highly promising direction for cancer treatment that uses a chemical drug to achieve the efficacy of both chemotherapy and immunotherapy. Herein, we report a high-throughput screening platform and the subsequent discovery of a new class of cancer immunogenic chemotherapeutic leads. Our platform integrates informatics-based activity metabolomics for the rapid identification of microbial natural products with both novel structures and potent activities.
