Compared to 7-8h of sleep, short sleep duration was linked to lower albumin levels [sleep duration [Formula see text] 5h β [Formula see text]-1.00, 95% CI (-1.26, -0.74), P < 0.0001]. Compared to 7-8h of sleep, long sleep duration was related to lower albumin levels [sleep duration [Formula see text] 9h β [Formula see text] -0.48, 95% CI (-0.68, -0.27), P < 0.0001]. Sleep duration had an inverted U-shaped relationship with albumin, with short or long sleep duration associated with significantly lower albumin levels.

The humerus fracture is one of the most commonly occurring fractures. In this research, we attempted to evaluate and compare the extent of malrotation and biomechanical environment after surgical treatment of humeral shaft fractures. A finite element (FE) model of the shoulder was built based on Computed Tomography (CT) data of a patient with a humeral shaft fracture. The muscle group around the shoulder joint was simulated by spring elements. The changes of shoulder stresses under rotation were analyzed. The biomechanics of the normal shoulder and postoperative malrotation of the humeral shaft was analyzed and compared. During rotations, the maximum stress was centered in the posterosuperior part of the glenoid for the normal shoulder. The von Mises shear stresses were 4.40MPa and 4.89MPa at 40° of internal and external rotations, respectively. For internal rotation deformity, the shear contact forces were 7-9 times higher for the shoulder internally rotated 40° than for the normal one. For external rotation deformity, the shear contact forces were about 3-5 times higher for the shoulder with 40° external rotation than the normal one. Postoperative malrotation of humeral shaft fracture induced the changes of the biomechanical environment of t
