Bioelectric Impedance Analysis and Pregnancy Outcomes
Pregnancy ComplicationsThis is a prospective observational study correlating Body Impedance Analysis (BIA) with pregnancy outcomes.

Longitudinal Early Epilepsy Study
Absence EpilepsyEpilepsy1 moreThis longitudinal study will focus on the cognitive and brain development of children with absence epilepsy. In addition, the investigators aim to identify prognostic factors for cognitive deterioration and/or poor seizure control in these children.

Periodontal Impact of Eating Disorders (the PERIOED Study)
Periodontal DiseasesEating Disorder2 moreThis study evaluated the periodontal status of patients suffering from eating disorders (anorexia nervosa and bulimia nervosa). The work hypothesis is that eating disorder patients have a higher risk for periodontal diseases than non-eating disorder subjects.

Discrimination of P and T Waves With Linq and Holter
ArrhythmiasCardiacCurrently loop recorders diagnose arrhythmias and send automatic alerts to physicians based on R to R relationships only. We believe arrhythmia diagnostics could be improved if accurate detection of P and T waves as well as QRS complexes were possible. There is no technique available for long term outpatient monitoring of QT intervals for patient at risk of torsade de pointes when receiving QT prolonging drugs. We believe that if an accurate T wave detection algorithm were developed loop recorders could be used to monitor the QT interval, and perhaps even provide alerts for patients at risk. The objective of this study is to see if an algorithm can be developed to accurately define P and T waves using data from an implantable loop recorder.

microRNA Profiles Identification in Adeno Carcinoma Prostate Cancer
Prostate CarcinosarcomaIn our study, the investigators want to find correlation between circulating miRNAs associated with prostate cancer metastases to bones and to lymph nodes separately with results of 68Ga-PSMA ligand PET (positron emission computed) imaging.

Chinese Adolescent Registry for Diabetes (CARD) Study
Chinese Adolescents With DiabetesThe CARD study is a observational study which includes Chinese adolescents with diabetes aged 18-30. The study aims to explore the status of disease treatment, self-management, the relationship between disease treatment and disease outcome in Chinese adolescents with diabetes.

Endoscopic Sleeve Gastroplasty
Morbid ObesityThe endoscopic sleeve gastroplasty allows stomach size reduction through an endoluminal suture approach without any incision. It could reduce the complications associated with current surgical techniques while obtaining the target gastric restriction, weight loss, comorbidities and quality of life improvement. The primary objective of this study is to assess weight loss after endoscopic sleeve gastroplasty in patients with morbid obesity.

Focussed Echocardiography to Detect Preoperative Hypovolemia and Left Ventricular Dysfunction as...
HypotensionThis is an observational study to evaluate the role of a Bed side Focus assessed Transthoracic Echocardiography (FATE) in identifying the patients at a potential risk of developing hypotension secondary to general anesthesia induction using the FATE parameters like velocity time integral ( VTI ), Inferior venacava diameter , Caval index and Left ventricular end end diastolic area.

Study About Lymphocytes Change During Menstrual Cycle in Women of Child-bearing Age
Lymphocyte Subsets in Women of Child-bearing AgeThe investigators are going to select the normal child-bearing period women as the study subjects and draw their peripheral blood to observe and analyze the change of quantity and percentage of lymphocyte subsets along with the change of menstrual cycle. Recording their BMI\menstrual history\and childbearing history, the investigators would select 300 healthy women in 6 different age groups which are aged 20-24, aged 25-29, aged 30-34, aged35-39, aged 40-44 and aged 45-49, then draw 1-2 ml blood form their peripheral vein (adding EDTA for anti-coagulation). The investigators are going to perform routine examination on the blood samples and detect T\B\NK lymphocyte through flow cytometry (FCM), thus calculating the absolute number of every species of lymphocyte. The investigators make assessment for the cellular immune function of the women during child-bearing period via comparing distinction in percentage and absolute number of every lymphocyte subset among reproductive-age women in different ages.
