Introduction: Citrate is commonly used as an anti¬coagulant during plateletpheresis procedure. The calcium chelating property of citrate may cause hypocalcaemia when the anticoagulated blood are returned to the donor’s circulation after selective removal of platelet. This study aims at investigating how regular plateletpheresis affects calcium level and bone density in the donors. Methods: A cross-sectional study was conducted among healthy donors at National Blood Centre, Kuala Lumpur, from 15th January till 31st March 2016. Donors were divided into two groups based on the frequency of plateletpheresis donation: low frequency group - donors who had donated less than 20 times, high frequency group - donors who had donated more than 50 times. Dual emission X-ray absorptiometry (DEXA) scan was performed to assess bone density. Pre-donation blood sampling was taken for albumin level. Calcium and magnesium levels were measured before and after donation. Results: Fifty donors participated in this study where the median age of participants was 35.0 years for low frequency and 45.2 years for high frequency group. There was no significant difference in the corrected calcium for both groups before and after plateletpheresis. However, the magnesium levels were significantly reduced in both arms (P<0.05). The albumin level and DEXA scan showed no significant differences between the groups. Conclusion: This study did not show any significant difference in calcium levels, albumin and bone density; but donors’ magnesium levels were reduced in low and high frequency donors after plateletpheresis.

Background: Post-menopausal women experiences changes in estrogen levels affecting body metabolism, which may lead to weight gain and obesity. Moreover, one of the most prevalent diseases among this group is osteoporosis. However, the relationship between fat mass and its protective property remains unclear. This study assesses the correlation of fat mass with bone mineral density (BM) and 10-year FRAX based fracture probability among Filipino women. Methods: A cross-sectional review of records of post-menopausal Filipino women who underwent whole body bone mineral densitometry scans via dual-energy X-ray absorptiometry (DXA) between January 1, 2015, and December 31, 2018 in the Radioisotope Laboratory of the Philippine General Hospital was done. Pearson correlation and simple linear regression analyses were done to determine the correlation between the two outcomes – BMD and 10-year FRAX based fracture probability. Results: A total of 258 postmenopausal women were included in the analysis. There was a weak positive correlation of fat mass with BMD of L1-L4 vertebrae (R-score of 0.318), BMD of femoral neck (R-score of 0.3937) and hips (R - score of 0.3031). The 10-year FRAX based fracture probability for both hip and osteoporotic had very weak and weak negative correlation, respectively (R-score of - 0.06752 and - 0.29017). Conclusion Despite having varying available, data on the protective effects of fat mass on fracture protection, this study showed that fat mass has a poor correlation with BMD and reduction in FRAX probability.
