Objective: To compare the weight bearing of men and women during standing and squatting after knee replacement surgery for osteoarthritis.
Design: Two-group, single-surgeon study with patients selected consecutively through a sample of convenience. Patients evaluated at first outpatient rehabilitation visit and at discharge from outpatient services.
Setting: Outpatient orthopedic institute.
Participants: Seventeen women (average age, 71 years) and 16 men (69 years) who underwent primary unilateral knee replacement for osteoarthritis.
Main Outcome Measurements: Percentage of body weight placed over the surgical limb during standing and during 30° and 60° squats.
Results: The men placed a greater percentage of body weight over the surgical limb during the 30° and 60° squats, both at the initial visit and at discharge. Both women and men had similar improvements with all dependent measurements.
Conclusion: The magnitude of change for women and men was similar, yet percentage of body weight placed over the surgical limb in women was less than in men at the initial visit and did not match that in their male counterparts by discharge.

[Albumin adjustment of total serum calcium - is it worth doing?].

Calcium is the most abundant mineral in the human body. About 99% of calcium is deposited in the bones in the form of hydroxyapatite and only 1% is located in the intracellular and extracellular fluid. Ionized calcium, which makes up about 50% of the total amount of circulating calcium, is biologically active; the remaining percentage is bound to plasma proteins (40%, of which albumin accounts for 90%, and globulins for 10%), or is in complex with anions (10%) such as citrate, lactate, bicarbonate, phosphate.
