Abstract Background Stress shielding after total hip arthroplasty (THA) leads to loss of bone mineral density (BMD) around the femoral implants, particularly in proximal area. Loss BMD implant is likely occur within 1 year THA; however, its severity depends on patient characteristics. This study evaluated preoperative factors correlated with zone 7 THA. Methods retrospective cohort included 48 ...

Total Hip Arthroplasty (THA) remains the gold standard of treatment for patients who suffer with a variety of hip-related pathological degeneration or trauma. These patients often exhibit significantly less post-operative pain and an increase in the range of motion of the joint, but there are still relatively common instances of debilitating periprosthetic complications that call into question ...

INTRODUCTION Rheumatoid arthritis (RA) is one of the major indications of total hip (THA) or knee (TKA) arthroplasty. International studies have suggested that RA is a risk factor for prosthesis infections. OBJECTIVES To compare patients with RA and patients with osteoarthritis (OA) of other etiologies with regard to the incidence of prosthesis, incisional, and other systemic postoperative in...

Este trabajo propone y evalúa una trayectoria hipotética de aprendizaje (THA) para los conceptos conjunto generador espacio generado. La THA se diseñó siguiendo el planteamiento Simon (1995), la heurística diseño modelos emergentes mecanismo reflexión sobre relación actividad-efecto. Se realizó un experimento con estudiantes universitarios evaluar si contribuyó al esperado conceptos. Para ello,...

Quality of life index (Quality Of Well-Being [QWB]) was used to calculate the costs per quality of well year (QWY) in total hip arthroplasty (THA) and compare it to other interventions. Ninety-eight primary and/or revision THA were reviewed. Patients had minimum 1-year follow-up. Quality of life index was used to calculate the costs per QWY in primary and revision THA. Preoperative QWB for prim...

The phantom midge, Chaoborus, is a dipteran, the larvae of which occur in many freshwater habitats and are known to be vulnerable to predation by fish. The hypothesis was tested that ovipositing imagines of Chaoborus use chemical cues to detect predatory fish and avoid depositing eggs into waterbodies containing fish kairomones. The experimental setup consisted of cages with two small water-fil...

• Example: sort the projects P in some order p1 . . . pn. • Either pn is part of some optimal solution to P , or it isn’t. Let Π∗ be this (unknown) optimal solution. • Π∗ consists of the result of our first choice (i.e., either pn or nothing), combined with some subset Π′ of the remaining projects. • If pn is part Π∗, then Π′ must consist only of projects in P that do not conflict with P ; that...

Concerns about the effects of global warming on crop yields have been raised due to stagnating yield progress in recent years. However, an understanding changes temperature and rainfall throughout cycle historical is lacking Europe (EU). In this study, positive wheat, barley, rice, maize EU (1961–2019) was significant, with rates 0.05, 0.04, 0.07 Tha?1year?1, for four crops respectively. Much h...
