The purpose of this study was to observe the effects of dietary intervention, through the modification of dietary fatty acids composition and antioxidant vitamins, on plasma thromboxane B2 (TXB2) levels in postmenopausal women with hypercholesterolemia. The subjects were treated for 12 weeks with one of three methods: hormone replacement therapy (HRT group, n=8), dietary intervention (DIET group, n=8), or HRT combined with dietary intervention (HRT +DIET group, n=8). Changes in serum phospholipid fatty acids composition, serum peroxides, and plasma TXB2 levels were measured at weeks 0, 4 and 12. The P/S ratio increased and the n-6/ n-3 ratio decreased in the DIET and the HRT +DIET group at week 4 (p<0.05). The ratio of C20:5/C20:4 in serum phospholipid increased in the DIET (p<0.05) and the HRT +DIET groups (NS) at week 4. Plasma TXB2 levels decreased in the DIET (-35%, p<0.05) and the HRT +DIET groups (-18.8%, NS) at week 4. Serum lipid peroxides levels significantly decreased by 10.5% and 15.2% in the DIET group at weeks 4 and 12, and by 10.8% in the HRT +DIET group only at week 12 (p<0.05). Dietary intervention may lower thrombotic risks in Korean postmenopausal women by changing the serum fatty acid composition, serum lipid peroxides levels and plasma thromboxane B2 levels.

Methods:
In retrospectively collected data, 149 patients who underwent single-level ACDF for degenerative disease were enrolled and divided into non-plating (n=66) and plating (n=83). Interspinous motion (ISM) at the arthrodesis segment, Numeric Rating Scale (NRS) for neck pain, and Neck Disability Index (NDI) were serially evaluated at 3, 6, and 12 months postoperatively. Predictable factors for fusion, including age, sex, plating, diabetes, smoking, and type of grafts, were investigated, and fusion was defined as ISM <1 mm.
Results:
In both groups, ISM was the highest at 3 months and gradually decreased thereafter, and the plating group showed significantly lower serial ISM than the non-plating group at 12 months. The plating group had lower NRS and NDI scores than the nonplating group at 12 months, and the difference in the NRS scores was statistically significant, particularly at 3 and 6 months, although that of the NDI scores was not. In a multivariate analysis, plating was the most powerful predictor for fusion.
Conclusions
Plating significantly decreases the serial ISM compared with non-plating in single-level ACDF, and such decreased motion is correlated with decreased neck pain until 12 months postoperatively, particularly at 3 and 6 months. Given that plating was the most predictive factor for fusion, we recommend plating even in single-level ACDF for better early clinical outcomes.
