Integrating Hydrogels and Biomedical Plastics via In Situ Physical Entanglements and Covalent Bonding.

Both rigid plastics and soft hydrogels find ample applications in engineering and medicine but bear their own disadvantages that limit their broader applications. Bonding these mechanically dissimilar materials may resolve these limitations, preserve their advantages, and offer new opportunities as biointerfaces. Here, a robust adhesion strategy is proposed to integrate highly entangled tough hydrogels and diverse plastics with high interfacial adhesion energy and strength.

Congenital Tracheal Stenosis With Complete Cartilage Rings: Proposal of A Multidisciplinary and Tailored Surgical Approach.

Introduction: Congenital Tracheal Stenosis (CTS) with complete cartilaginous rings is a rare but potentially life-threatening condition in paediatric patients. Currently, the most common approach is slide tracheoplasty (ST) with sternotomy under cardiopulmonary bypass (CPB). Intending to make the procedure less invasive and consider the variety of associated conditions, we have tailored the approach to our patients, who were treated by a multidisciplinary airway team.

Sex-based differences in risk of revision for infection after hip, knee, shoulder, and ankle arthroplasty in osteoarthritis patients: a multinational registry study of 4,800,000 implants.

Background And Purpose:  We aimed to determine sex differences for periprosthetic joint infections after primary arthroplasty of the hip, knee, ankle, and shoulder in osteoarthritis patients in an international perspective.

Methods:  This is a multinational combined arthroplasty registry study. Each arthroplasty registry performed Cox-regression analysis of their data and reported the crude and adjusted hazard ratios (HR) with an a priori designed data form.
