Change in bone mineral density in post menopausal women with rheumatoid arthritis
Introduction: Low bone mass is a serious complication of post menopausal women with rheumatoid arthritis. We determined the Change in Bone Mineral Density in postmenopausal women with rheumatoid arthritis. Methods: This retrospective cohort study was carried out on consecutive postmenopausal women with rheumatoid arthritis who were referred to the Azar 5th teaching hospital affiliated to Golestan University of Medical Sciences, North of Iran in 2009. The required data were gathered from the patients' medical records. The data were analyzed using SPSS software and statistical tests. Results: We studied 98 postmenopausal women with rheumatoid arthritis. Mean number of years since menopause and mean duration of disease were 9.39 and 5.13 respectively. T Score mean in femoral neck and lumbar spines was -1.45±1.26 and -2.45±1.44 respectively. The overall prevalence of osteoporosis at both the lumbar spine and femoral neck was 13.3. We have found a significant correlation between age, duration of disease, duration of menopause and bone mineral density (P-Value<0.01). Conlusion: Our results indicate a negative effect of age, number of years since menopause and duration of disease on bone mineral density. So, BMD should be measured in high risk women prior to the implementation of any treatment or prevention program
Effect of intermittent normal saline bolus during hemodialysis on adequacy of dialysis
Background and purpose: Using practical and non-invasive methods to improve the adequacy of dialysis (i.e. Kt/V) can increase the quality of life and decrease the mortality and morbidity rate in patients under hemodialysis. This study was conducted to investigate the effect of intermittent normal saline bolus on adequacy of dialysis. Materials and methods: In this randomized controlled cross-over clinical trial, 51 patients were chosen based on inclusion criteria and were randomly assigned into two groups. Before the intervention, the Kt/V and Urea Reduction Ratio (URR) of the last session of dialysis (baseline) were measured in all patients. The control group were dialyzed conventionally (heparinized dialysis), but the intervention group received 100 ml normal saline bolus every hour, within three times. In three subsequent sessions, as a washout period, all patients received conventional hemodialysis. Then the patients were swapped and all steps were repeated. Results: Before the intervention, there were no significant differences between the two groups in age, sex, duration of dialysis, type of vascular access, adequacy of dialysis, and Urea Reduction Ratio (P>0.05). Compared with baseline, the Kt/V and URR mean values increased by 16 and 8 in intervention group, respectively (P<0.01) but these values decreased in control group. In addition, findings revealed significant differences in Kt/V and URR mean values between the two groups after using normal saline bolus intermittently (P< 0.01). Conclusion: Using intermittent normal saline bolus during hemodialysis improves adequacy of dialysis. © 2018, Mazandaran University of Medical Sciences. All rights reserved
