Return to Work Following Hip or Knee Arthroplasty: A One-Year Prospective Cohort Study in Participants with Direct Referral from Hospital to Occupational Health Care Services.

Purpose: In a new Finnish Coordinated Return to Work (CRTW) model, patients are referred to occupational health care after hip or knee arthroplasty. This study evaluated the CRTW model's effect on return to work (RTW), activities used in occupational health care and in the workplace, and the patient- and work-related factors affecting early RTW.

Methods: 209 participants with occupational health care service underwent primary hip (THA) or total/unicondylar knee (KJA) arthroplasty and completed self-reported questionnaires after arthroplasty and at time of RTW.

Collagenase-2 (matrix metalloproteinase-8) plays a protective role in tongue cancer.

Squamous cell carcinoma (SCC) of the tongue is the most common cancer in the oral cavity and has a high mortality rate. A total of 90 mobile tongue SCC samples were analysed for Bryne's malignancy scores, microvascular density, and thickness of the SCC sections. In addition, the staining pattern of cyclooxygenase-2, alphavbeta6 integrin, the laminin-5 gamma2-chain, and matrix metalloproteinases (MMPs) -2, -7, -8, -9, -20, and -28 were analysed.
