[Q]: Context: The aim of this clinical study were to compare the clinical efficacy of ankaferd blood stopper (ABS) when used in combination with autogenous cortical bone graft (ACB) in the treatment of intrabony periodontal defects.', 'The study was planned as a split-mouth design. Fifteen patients with chronic periodontitis at 30 sites (six men, nine women; 42 ± 7 years) were included. Treatment sites had probing pocket depths (PPD) of ≥ 6 mm and osseous defect depths of ≥ 4 mm as radiographically assessed. Following the initial periodontal therapy, patients were randomly assigned to two treatments in contralateral areas of the dentition: ACB + ABS or ACB alone. At baseline and 6 mo after surgery, clinical parameters of plaque index, gingival index, PPD, clinical attachment level and gingival recession (GR) were recorded. The primary outcome variable was the change in clinical attachment level between baseline and 24 wk after surgery. Gingival crevicular fluid samples were collected immediately before surgery and at 2, 4, 6, 12 and 24 wk after the surgery. Gingival crevicular fluid volume was calculated and vascular endothelial growth factor levels in gingival crevicular fluid were measured.', 'PPD decreased, clinical attachment level improved and gingival index decreased significantly in response to both modes of treatment (p < 0.05). Both treatment modalities resulted in a significant gain in radiographic bone levels compared to baseline (p < 0.05). Intergroup comparisons showed that there was a significantly higher gain in clinical attachment level in the ABS/ACB group compared to ACB group (p < 0.05) with significantly less GR (p < 0.05). Similarly, vascular endothelial growth factor concentration in gingival crevicular fluid was significantly higher in the ABS/ACB group at postoperative weeks 2 and 4 compared to the ACB group (p < 0.01).
Answer: The findings suggest that ABS enhances the soft tissue healing during the periodontal defect fill by the ACB by stimulating angiogenesis and vascular endothelial cell function, prevents GR and thereby increases the clinical attachment gain.
[A]: Does ankaferd blood stopper enhance healing after osseous grafting in patients with intrabony periodontal defects?


[Q]: Context: The aim of this study was to investigate the association of lipoprotein(a) [Lp(a)] with the severity of coronary heart disease (CHD) in Han Chinese people.', 'Six hundred and seventy-nine patients with angiographically defined CHD were enrolled in this cross-sectional study. Fasting lipids were measured, and the severity of CHD was quantitatively assessed for each patient according to the number of stenotic coronary branches and the Gensini scoring system.', 'The levels of Lp(a), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), very low-density lipoprotein cholesterol (VLDL-C), and apolipoprotein (apo) B100 increased, while high-density lipoprotein cholesterol (HDL-C) and apoAI decreased significantly with the number of stenotic vessels. The levels of Lp(a) increased and HDL-C and apoAI decreased significantly with the Gensini scores. The logistic regression analyses showed that Lp(a) and HDL-C were independently associated with the number of stenotic coronary vessels after adjusting for age, weight, body mass index, sex, smoking, alcohol consumption, hypertension, diabetes, triglycerides, TC, LDL-C, VLDL-C, apoAI, and apoB100. However, only Lp(a) was independently associated with the Gensini scores after adjustment.
Answer: Our data indicate that Lp(a) might be a useful marker in predicting the severity of coronary heart disease.
[A]: Are plasma lipoprotein ( a ) levels associated with the severity of coronaryheart disease in Han Chinese people?


[Q]: Context: Violence and safety exposures, primarily in the form of intimate partner violence (IPV) exposures, have been associated with increased healthcare utilization in women and variable associations with preventive services. It remains unknown, however, if broader measures of violence and safety exposures are associated with preventive healthcare utilization.', 'Data from the 2004 The Philadelphia Health Management Corporation survey were used to compare self-reported utilization of preventive healthcare services for participants who did and did not report exposures to violence or have safety concerns during the past year, using novel but nonvalidated measures of violence and safety concerns. The sample included women aged 18-96 years who reported having a usual source of care. Measures of preventive healthcare utilization included timing of last mammogram, cervical cytology, breast examination, blood cholesterol testing, blood pressure measurement, and screening for colon cancer.', 'The survey had an American Association for Public Opinion Research response rate of 30.4%. Of the 6285 women surveyed who reported having a usual source of care, 456 (7.3%) reported either an exposure to violence or safety concerns, and 5821 did not. Using logistic regression models, women aged 18-65 years who reported safety concerns were less likely to report having cervical cancer testing in the past 12 months (OR 0.68, 95% CI 0.49-0.94). Women > or =40 years who reported safety concerns in the last year were less likely to report having clinical breast examinations (OR 0.63, 95% CI 0.43-0.93) or mammography (OR 0.57, 95% CI 0.39-0.83). Physical violence exposure was not significantly associated with preventive healthcare utilization.
Answer: In this large population-based sample, women with recent self-reported safety concerns report receiving fewer recommended gender-specific preventive services.
