It was recently hypothesized the existence of "cardiac-skeletal muscle axis." However, the relationship between skeletal muscle mass (SMM) and left ventricular mass (LVM) has never been investigated in the specific group of older individuals with low skeletal mass and physical performance. We tested this hypothesis in the SPRINT-T (Sarcopenia and Physical Frailty IN older people: multicomponenT Treatment strategies Trial) population using LVM as independent variable and SMM as dependent variable. ⋯ In a sample of older persons with low muscle mass and physical performance, LVM was positively and significantly correlated with ALM, independently from blood pressure, physical activity, and other potential confounders. Future studies are needed to address the effect of interventions targeting LVM and SMM.

Few prior studies have evaluated recovery after the onset of severe disability or have distinguished between the two subtypes of severe disability. ⋯ Recovery of independent function is considerably more likely after the onset of catastrophic than progressive severe disability, the risk factors for reduced recovery differ between progressive and catastrophic severe disability, and subsequent exposure to intervening illnesses and injuries considerably diminishes the likelihood of recovery from both subtypes of severe disability.

Physical activity is associated with improved pain, functional status, and less disability in persons with knee osteoarthritis (KOA). Because polypharmacy is related to several adverse health outcomes in older persons, we hypothesized that it might also be associated with decreased physical activity in those with KOA. This study evaluates the relationship between the number of prescription medications and weekly moderate to vigorous physical activity (MVPA). ⋯ An increased number of prescription medications and polypharmacy are associated cross-sectionally with decreased MVPA in adults with KOA. Further study is necessary to establish the causal nature of this association.

Using available literature, our aim was to design a firearm safety counseling protocol tool for dementia patients. ⋯ Providing standardized and effective clinical guidelines to healthcare providers who interact with firearm-owning PWD can act as a means to reduce firearm injury and violence. The protocol proposed in this article needs further testing and validation to determine if it will help reduce firearm-related events in PWD.

Action Seniors! Cost-Effectiveness Analysis of a Secondary Falls Prevention Strategy Among Community-Dwelling Older Fallers.
The Otago Exercise Program (OEP) has demonstrated cost-effectiveness for the primary prevention of falls in a general community setting. The cost-effectiveness of exercise as a secondary falls prevention (ie, preventing falls among those who have already fallen) strategy remains unknown. The primary objective was to estimate the cost-effectiveness (incremental cost-effectiveness/utility ratio) of the OEP from a healthcare system perspective. ⋯ Compared with usual care, healthcare system costs are saved and falls are prevented when older fallers who attend a geriatrician-led falls clinic are allocated to, and provided, the physiotherapist-guided exercise-based falls prevention program (the OEP).
