Arthroscopic Autologous Iliac Crest Grafting With an Adjustable-Loop Suspensory Device Yields Favorable Outcomes for Anterior Shoulder Instability With Glenoid Defects.

Purpose: To evaluate the clinical and radiologic outcomes of the arthroscopic autologous iliac crest grafting (AICG) procedure with an adjustable-loop suspensory fixation device in the treatment of anterior shoulder instability with glenoid bone defects.

Methods: A retrospective review was conducted on the patients who underwent arthroscopic AICG with an adjustable-loop suspensory fixation device from January 2017 to December 2020. Patients with traumatic anterior shoulder instability, significant glenoid bone defects, and a minimum follow-up of 24 months were included.

Photocontrolled Reversible Solid-Fluid Transitions of Azopolymer Nanocomposites for Intelligent Nanomaterials.

Intelligent polymer nanocomposites are multicomponent and multifunctional materials that show immense potential across diverse applications. However, to exhibit intelligent traits such as adaptability, reconfigurability and dynamic properties, these materials often require a solvent or heating environment to facilitate the mobility of polymer chains and nanoparticles, rendering their applications in everyday settings impractical. Here intelligent azopolymer nanocomposites that function effectively in a solvent-free, room-temperature environment based on photocontrolled reversible solid-fluid transitions via switching flow temperatures (Ts) are shown.

Is playing ma-jong, chess and cards associated with a lower incidence of shoulder pain in Chinese elderly adults? The cross-sectional and longitudinal evidence from CHARLS.

Background: The association between playing Ma-jong, chess and cards (PMCC) and shoulder pain among elderly adults in China remains unclear. The present study aimed to examine the association based on a nationally representative large-scale survey.

Methods: The study used two waves of data from China Health and Retirement Longitudinal Study (CHARLS) in 2015 and 2018.

Adipose-derived stem cell-based optimization strategies for musculoskeletal regeneration: recent advances and perspectives.

Musculoskeletal disorders are the leading causes of physical disabilities worldwide. The poor self-repair capacity of musculoskeletal tissues and the absence of effective therapies have driven the development of novel bioengineering-based therapeutic approaches. Adipose-derived stem cell (ADSC)-based therapies are being explored as new regenerative strategies for the repair and regeneration of bone, cartilage, and tendon owing to the accessibility, multipotency, and active paracrine activity of ADSCs.

Shape-Morphing Liquid-Crystal polymers.

Liquid-crystal polymers are a type of representative material combining the order-disorder transition of liquid crystals and the superior properties of polymers. The phase transition from the liquid-crystal phase to the isotropic state of mesogens causes large, controllable, and reversible deformation of polymers; thus, liquid-crystal polymers have emerged as one of the most valuable candidates for shape-morphing materials. Therefore, this review will focus on the recent development of shape-morphing liquid-crystal polymers, including the modes of energy conversions, material design strategies and further applications.

Decreased numbers and sex-based differences of circulating regulatory T cells in patients with seropositive undifferentiated arthritis.

Aims: CD4 T cells play crucial roles as both mediators and regulators of the pathogenesis of rheumatoid arthritis (RA). However, the characteristics of CD4 T cell subpopulations in the earliest stage of RA development remain unclear. Hence, we determined the proportions and absolute counts of circulating CD4 T cell subsets in patients with seropositive undifferentiated arthritis (SUA), the early and preclinical stage of RA.
