3. bloodstream infection(English)

   • Infectious disease defined by the presence of viable bacterial or fungal microorganisms in the bloodstream. Includes infective endocarditis, central venous catheter-associated bloodstream infections, primary bacteremia, and those with secondary bacteremia due to focal infections including abscesses, osteomyelitis, urinary tract infections, or pneumonia. It is a major cause of morbidity and mortality despite the availability of broad spectrum and effective antimicrobials and major advances in supportive care; aka sepsis

5. bone stress injury(English)

   • occurs when bone is no longer able to withstand repetitive, mechanical loading. Lesser trochanter type is less common compared with femoral neck BSI. Means that the bones cannot tolerate repeated mechanical loads, resulting in structural fatigue and local bone pain

8. bone strength index(English)

   • combines bone mineral and bone biomechanical properties to measure resistance to bending. This index may have greater clinical significance than the more often described markers of bone mineral content, areal density, or geometry alone and, in turn, may show a stronger relation to fracture risk. The BSI is the product of volumetric cortical bone mineral density and cross sectional moment of inertia within a region of interest
