Effect of Antiseptic Irrigation Solutions on Primary Human Knee Fibroblasts Cultured in Human Platelet Lysate.

Background: Native and periprosthetic joint infections are devastating conditions fraught with patient morbidity and mortality. Aseptic and septic joints are often debrided and irrigated to decrease bacterial loads when preventing or treating infection. However, the effect of clinically used irrigation solutions on the native cellular components of the synovial joint is unknown.

Results of 331 Two-Stage Exchanges for PJI Following THA: Low Reinfection and Mechanical Failure Rates at 10 Years.

Background: The relative advantages and disadvantages of 2-stage versus 1-stage management of infection following total hip arthroplasty (THA) are the current subject of intense debate. To understand the merits of each approach, detailed information on the short and, importantly, longer-term outcomes of each must be known. The purpose of the present study was to assess the long-term results of 2-stage exchange arthroplasty following THA in one of the largest series to date.

Safety of adipose-derived stromal vascular fraction cells to treat Parkinson's disease.

Neuroinflammation is a significant correlate of Parkinson's Disease (PD), with positron emission tomography showing microglial activation early in the PD process and post-mortem tissue containing reactive microglia. Adipose-derived (AD) stromal vascular fraction (SVF) cells have been shown to respond to pro-inflammatory conditions with secretion of anti-inflammatory paracrine factors. This pilot clinical trial was to examine the safety and clinical response using autologous ADSVF to treat PD.

Role of thermosensitive transient receptor potential (TRP) channels in thermal preference of male and female mice.

Transient Receptor Potential (TRP) ion channels are important for sensing environmental temperature. In rodents, TRPV4 senses warmth (25-34 °C), TRPV1 senses heat (>42 °C), TRPA1 putatively senses cold (<17 °C), and TRPM8 senses cool-cold (18-26 °C). We investigated if knockout (KO) mice lacking these TRP channels exhibited changes in thermal preference.
