Filter by:This interventional study investigates the efficacy of Wet cupping therapy on heavy metal levels.The levels of the selected heavy metals will be measured in the blood samples obtained from the participants before and after the interventions
The aim of the study was to define the possible association between heavy iron level and the consequence of pregnancy especially spontaneous abortion and missed abortion. The study population will comprised the first-trimester pregnant women in the PUMCH (Peking Union Medicine College Hospital) during 2017 October to 2018 November. We categorised the patients into two groups, the study group where the patients suffered from spontaneous abortion or missed abortion, and the control group where the patients carry the normal live fetal for at least 8 weeks and ask for artificial abortion. All the cases included in the study were examined with respect to 6 kinds of heavy iron level in venous blood and urine, then correlation analysis was applied to define heavy iron level between two groups.
The researchers propose to investigate the prevalence of gadolinium in the urine of patients with a prior gadolinium-enhanced MRI before and after a edetate calcium disodium challenge. Moreover, will investigate if there is any correlation of gadolinium urine levels with levels of endogenous (e.g zinc) and xenobiotic metals.
The present study aims is to investigate: 1. whether patients suffering from acute resp. chronic ischemic heart disease show higher levels for cadmium (Cd), lead (Pb) and mercury (Hg) than local and international reference levels suggest; 2. the correlation between severity of coronary artery disease and angiogenic and angiostatic factors (endostatin-ES, angiostatin-AS, VEGF-vascular endothelial growth factor, osteopontin-OPN) The patient population consists of about 270 female and male patients suffering either acute or chronic ischemic heart disease (AIHD:ICD-10 I21; CIHD: ICD-10 I25). 3. whether patients suffering CAD and valve calcification (mitral annulus, aortic valve) show higher levels of endostatin, angiostatin, osteopontin and VEGF compared to patients with CAD but without valve (annulus) calcification The measurement of cadmium (urine), lead, mercury, zinc, endostatin, angiostatin, VEGF (serum) and osteopontin (plasma) in patients with angiographically verified coronary artery disease are in the fore. Furthermore, basic laboratory diagnostics as well as data from coronary angiography and echocardiography will be collected. Additionally, the investigators will inquire heavy metal exposition during life by an interview. Recruitment will be done during the in-patient stay at the General Hospital of Vienna, Medical University of Vienna.
