Tranexamic Acid Reduces Total Blood Loss and Inflammatory Response in Computer-Assisted Navigation Total Knee Arthroplasty.

Introduction: Tranexamic acid (TXA) is an effective blood salvage agent that reduces perioperative blood loss in conventional total knee arthroplasty (TKA). As computer-assisted surgery for TKA (CAS-TKA) results in a lower perioperative blood loss than conventional TKA, the additional effect of blood conservation by TXA might be mitigated. This study aimed to evaluate the efficacy of TXA in CAS-TKA.

Effects of computer-assisted navigation versus conventional total knee arthroplasty on the levels of inflammation markers: A prospective study.

Total knee arthroplasty (TKA) is a well-established modality for the treatment of advanced knee osteoarthritis (OA). However, the detrimental effects of intramedullary reaming used in conventional TKA for distal femur cutting are of concern. Avoiding intramedullary reaming with the use of computer-assisted navigation TKA can not only provide superior prosthetic alignment, but also mitigate perioperative blood loss and the dissipation of marrow emboli.

Increased expression of type 1 cannabinoid (CB1) receptor among patients with rotator cuff lesions and shoulder stiffness.

Background: Shoulder stiffness is a disease manifested by pain, limited range of motion, and functional disability. The inflammatory and fibrosis processes play a substantial role in the pathogenesis of shoulder stiffness. The CB1 receptor has been recognized to mediate the processes of pathologic fibrosis.

Microvascular dysfunction with increased vascular leakage response in mice systemically exposed to arsenic.

The mechanisms underlying cardiovascular disease induced by arsenic exposure are not completely understood. The objectives of this study were to investigate whether arsenic-fed mice have an increased vascular leakage response to vasoactive agents and whether enhanced type-2 protein phosphatase (PP2A) activity is involved in mustard oil-induced leakage. ICR mice were fed water or sodium arsenite (20 mg/kg) for 4 or 8 weeks.
