#1
REVIEW
Dan Clark, Mary Nakamura, Ted Miclau, Ralph Marcucio
PURPOSE OF REVIEW: This review summarizes research on the physiological changes that occur with aging and the resulting effects on fracture healing. RECENT FINDINGS: Aging affects the inflammatory response during fracture healing through senescence of the immune response and increased systemic pro-inflammatory status. Important cells of the inflammatory response, macrophages, T cells, mesenchymal stem cells, have demonstrated intrinsic age-related changes that could impact fracture healing...

REVIEW
Sharon H Chou, Meryl S LeBoff
PURPOSE OF REVIEW: Vertebral fractures are the most common osteoporotic fracture and result in functional decline and excess mortality. Dual-energy x-ray absorptiometry (DXA) is the gold standard for the diagnosis of osteoporosis to identify patients at risk for fragility fractures; however, advances in imaging have expanded the role of computed tomography (CT) and magnetic resonance imaging (MRI) in evaluating bone health. RECENT FINDINGS: The utility of CT and MRI in the assessment of bone density is starting to gain traction, particularly when used opportunistically...

REVIEW
Erika Barboza Prado Lopes, Adrian Filiberti, Syed Ali Husain, Mary Beth Humphrey
PURPOSE OF THE REVIEW: Mounting evidence supports a role of low-grade inflammation in the pathophysiology of osteoarthritis (OA). We review and discuss the role of synovitis, complement activation, cytokines, and immune cell population in OA. RECENT FINDINGS: Using newer imaging modalities, synovitis is found in the majority of knees with OA. Complement activation and pro-inflammatory cytokines play a significant role in the development of cartilage destruction and synovitis...

Hubertine M E Willems, Ellen G H M van den Heuvel, Ruud J W Schoemaker, Jenneke Klein-Nulend, Astrid D Bakker
PURPOSE OF REVIEW: Multiple dietary components have the potential to positively affect bone mineral density in early life and reduce loss of bone mass with aging. In addition, regular weight-bearing physical activity has a strong positive effect on bone through activation of osteocyte signaling. We will explore possible synergistic effects of dietary components and mechanical stimuli for bone health by identifying dietary components that have the potential to alter the response of osteocytes to mechanical loading...

PURPOSE OF REVIEW: Chronic non-bacterial osteomyelitis (CNO) with its most severe form chronic recurrent multifocal osteomyelitis (CRMO) is an autoinflammatory bone disorder. We summarize the clinical presentation, diagnostic approaches, most recent advances in understanding the pathophysiology, and available treatment options and outcomes in CNO/CRMO. RECENT FINDINGS: Though the exact molecular pathophysiology of CNO/CRMO remains somewhat elusive, it appears likely that variable defects in the TLR4/MAPK/inflammasome signaling cascade result in an imbalance between pro- and anti-inflammatory cytokine expressions in monocytes from CNO/CRMO patients...

#6
REVIEW
Jay J Cao
PURPOSE OF REVIEW: Consumption of high-protein diets is increasingly popular due to the benefits of protein on preserving lean mass and controlling appetite and satiety. The paper is to review recent clinical research assessing dietary protein on calcium metabolism and bone health. RECENT FINDINGS: Epidemiological studies show that long-term, high-protein intake is positively associated with bone mineral density and reduced risk of bone fracture incidence. Short-term interventional studies demonstrate that a high-protein diet does not negatively affect calcium homeostasis...

#8
REVIEW
Didier Hans, Emőke Šteňová, Olivier Lamy
PURPOSE OF THE REVIEW: There is an increasing body of evidence that the trabecular bone score (TBS), a surrogate of bone microarchitecture extracted from spine DXA, could play an important role in the management of patients with osteoporosis or at risk of fracture. The current paper reviews this published body of scientific literature on TBS and answers the most relevant clinical questions. RECENT FINDINGS: TBS has repeatedly been proven to be predictive of fragility fractures, current and future, and this is largely independent of BMD, CRF, and the FRAX, and when used in conjunction with any one of these measures, it consistently enhances their accuracy...

REVIEW
Wolfgang Kemmler, Simon von Stengel, Matthias Kohl
PURPOSE OF REVIEW: Due to older people's low sports participation rates, exercise frequency may be the most critical component for designing exercise protocols that address fracture risk. The aims of the present article were to review and summarize the independent effect of exercise frequency (ExFreq) on the main determinants of fracture prevention, i.e., bone strength, fall frequency, and fall impact in older adults. RECENT FINDINGS: Evidence collected last year suggests that there is a critical dose of ExFreq that just affects bone (i...

REVIEW
Haniyeh Hemmatian, Astrid D Bakker, Jenneke Klein-Nulend, G Harry van Lenthe
PURPOSE OF REVIEW: The bone is able to adapt its structure to mechanical signals via the bone remodeling process governed by mechanosensitive osteocytes. With aging, an imbalance in bone remodeling results in osteoporosis. In this review, we hypothesized that changes in lacunar morphology underlie the decreased bone mechanoresponsiveness to mechanical loading with aging. RECENT FINDINGS: Several studies have reported considerable variations in the shape of osteocytes and their lacunae with aging...
