Pain and Frailty in Childhood Cancer Survivors: A Narrative Review.

A significant proportion of childhood cancer survivors experience persistent health problems related to cancer or cancer treatment exposures, including accelerated or early onset of aging. Survivors are more likely than non-cancer peers to present a frail phenotype suggestive of reduced physiologic reserve and have symptoms that interfere with function in daily life, including pain. Studies in the general population, mostly among older adults, suggest that pain is a significant contributor to development and progression of frail health.

Bone Marrow Stromal Cells Generate a Pro-Healing Inflammasome When Cultured on Titanium-Aluminum-Vanadium Surfaces with Microscale/Nanoscale Structural Features.

The surface topography and chemistry of titanium-aluminum-vanadium (Ti6Al4V) implants play critical roles in the osteoblast differentiation of human bone marrow stromal cells (MSCs) and the creation of an osteogenic microenvironment. To assess the effects of a microscale/nanoscale (MN) topography, this study compared the effects of MN-modified, anodized, and smooth Ti6Al4V surfaces on MSC response, and for the first time, directly contrasted MN-induced osteoblast differentiation with culture on tissue culture polystyrene (TCPS) in osteogenic medium (OM). Surface characterization revealed distinct differences in microroughness, composition, and topography among the Ti6Al4V substrates.

Microlipophagy from Simple to Complex Eukaryotes.

Lipophagy is a selective degradation of lipid droplets in lysosomes or vacuoles. Apart from its role in generating energy and free fatty acids for membrane repair, growth, and the formation of new membranes, lipophagy emerges as a key player in other cellular processes and disease pathogenesis. While fungal, plant, and algal cells use microlipophagy, the most prominent form of lipophagy in animal cells is macrolipophagy.

Constraint of Different Knee Implant Designs Under Anterior-Posterior Shear Forces and Internal-External Rotation Moments in Human Cadaveric Knees.

Instability remains one of the most common indications for revision after total knee arthroplasty. To gain a better understanding of how an implant will perform in vivo and support surgeons in selecting the most appropriate implant design for an individual patient, it is crucial to evaluate the implant constraint within clinically relevant ligament and boundary conditions. Therefore, this study investigated the constraint of three different implant designs (symmetrical implants with and without a post-cam mechanism and an asymmetrical medial-stabilized implant) under anterior-posterior shear forces and internal-external rotation moments at different flexion angles in human cadaveric knees using a six-degrees-of-freedom joint motion simulator.
