Are the D9N , N291S and S447X variants in the lipoprotein lipase ( LPL ) gene associated with Type III hyperlipidemia?
It is unlikely that the D9N, N291S or S447X variants in the LPL gene play an important role in the development of Type III HLP.
Independent of postoperative improvement in pain, disability, and quality of life, the extent of preoperative depression was an independent predictor of time to return to work in patients undergoing TLIF for spondylolisthesis, suggesting that regardless of how successful TLIF surgery may be at improving a patient's pain, disability, or quality of life, greater depression will delay or prohibit their ability to return to work postoperatively.
