Background/objectives: Destructive metastatic lesions about the acetabulum result in pain and functional limitations. We assessed whether periacetabular reconstruction (PAR) improves quality of life by examining outcome measures of pain, function, and mobility.
Methods: Thirty-seven patients with a mean follow-up of 23.6 months (range, 0.5-112 months) were retrospectively reviewed. All patients underwent modified Harrington reconstruction with periacetabular screws, cement, and total hip arthroplasty.
Results: The mean preoperative MSTS score of 14 (47%, 14/30) improved to 20 (67%, 20/30) after the procedure. Thirty-five patients who were alive 1 month after the procedure were reviewed for outcome. Postoperatively, patients reported a significant improvement in pain (P < 0.0001), mobility (P < 0.0385), and function (P < 0.0186). Kaplan-Meier survivorship curves showed 59% implant- and 55% patient survival at 2 years; and 49% implant- and 39% patient survival at 5 years. Complications included infection (16%, 6/37) and instability (16%, 6/37).
Conclusions: Our experience with PAR has shown good results with improved postoperative functional scores. Implants will generally exceed life expectancy and are an option to restore quality of life.

Background: Although determinants and strategies for implementing a cancer rehabilitation navigation (CRNav) program have been described, defining specific implementation interventions could improve uptake in oncology care delivery. This manuscript shares prioritized implementation interventions using a multilevel framework.
Methods: We convened interdisciplinary stakeholders from two CRNav programs to participate in an implementation mapping focus group.

Background: The pelvis is one of the most common areas for metastatic bone disease. We recently described the use of a minimally invasive percutaneous screw fixation of metastatic non-periacetabular pelvic lesions, with excellent results.
Description: The procedure can be completed in a standard operating theater without the need for special instruments.

Bone metastasis in the periacetabular region usually causes severe pain and functional disability. Some surgical procedures, such as the Harrington surgery and percutaneous cementoplasty, have been reported as treatment options for periacetabular bone metastases with limited efficacy. The former is highly invasive, while the latter may not allow the injection of a sufficient amount of cement.

Mussels and tubeworms have evolved similar adhesive systems to cope with the hydrodynamics of intertidal environments. Both secrete adhesive proteins rich in DOPA, a post-translationally modified amino acid playing essential roles in their permanent adhesion. DOPA is produced by the hydroxylation of tyrosine residues by tyrosinase enzymes, which can also oxidize it further into dopaquinone.

The negative interference of treatments between the acetylcholinesterase inhibitor rivastigmine and the tau aggregation inhibitor hydromethylthionine mesylate (HMTM) has been reported in Line 1 tau-transgenic mice, which overexpress a truncated species of tau protein that is found in the core of paired helical filaments in Alzheimer´s disease (AD). However, little is known about whether such interactions could affect synapses in mice overexpressing tau carrying pathogenic mutations. Here, we have used Line 66 (L66) mice which overexpress full-length human tau carrying the P301S mutation as a model in which tau accumulates in synapses.
