"I'm Getting Older Too": Challenges and Benefits Experienced by Very Old Parents and Their Children.

Very old parents and their "old" children are a growing group in industrialized countries worldwide. However, virtually nothing is known about the nature and implications of this relationship constellation. To fill this gap, this study explored the challenges and rewards of the very old parent-child relationship.

Cognitive Functioning, Gender, and Marital Quality Among Older Married Couples: A Dyadic Approach.

This study examines associations of older husbands' and wives' cognitive functioning with both partners' marital quality. Generalized structural equation modeling analyzed data from 1,432 opposite-sex couples drawn from the 2016 wave of the Health and Retirement Study. Findings revealed that wives' poorer cognitive functioning was associated with wives reporting greater closeness and enjoyment of time with a spouse, whereas husbands' poorer cognitive functioning was associated with wives reporting greater marital strain, lower marital support, lower closeness, and less enjoyment of time with a spouse.

Finite element investigation into the use of carbon fibre reinforced PEEK laminated composites for distal radius fracture fixation implants.

Carbon fibre reinforced PEEK (CF/PEEK) laminates provide mechanical advantages over homogenous metal osteo-synthesis implants, e.g. radiolucency, fatigue strength and strength to weight ratio.

Multi-axial damage and failure of medical grade carbon fibre reinforced PEEK laminates: Experimental testing and computational modelling.

Orthopaedic devices using unidirectional carbon fibre reinforced poly-ether-ether-ketone (PEEK) laminates potentially offer several benefits over metallic implants including: anisotropic material properties; radiolucency and strength to weight ratio. However, despite FDA clearance of PEEK-OPTIMA™ Ultra-Reinforced, no investigation of the mechanical properties or failure mechanisms of a medical grade unidirectional laminate material has been published to date, thus hindering the development of first-generation laminated orthopaedic devices. This study presents the first investigation of the mechanical behaviour and failure mechanisms of PEEK-OPTIMA™ Ultra-Reinforced.
