Aim of the study is to evaluate different regional anesthesia regimes for thoracoscopic surgery to evaluate their efficiency in (postoperative) pain control. Three regional anesthesia forms are evaluated: thoracic epidural anesthesia, (ultrasound-guided) serratus-anterior-plane-block an local infiltration with local anesthetic at the site of performing the thoracoscopy.

The goal of this research study is to understand the relationship between the hormone oxytocin and postpartum mood. Based on previous research, the investigators hypothesize that lower plasma oxytocin concentration during pregnancy will predict a greater likelihood of postpartum depression. Second, it is expected that oxytocin concentration in the third trimester will show an inverse relationship with the severity of depressive symptoms at 4 - 6 weeks postpartum. Potential participants in the study will be screened for eligibility during their third trimester of pregnancy, using a combination of questionnaires. Those who are eligible for participation will have one blood sample drawn at this time, and then be asked to complete a follow up questionnaire at 4-6 weeks postpartum to assess for depressive mood symptoms. This follow up questionnaire can be completed either in person or on the telephone. Anyone who is interested in receiving help for their mood at any point in the study will receive referrals.

The purpose of this study is to assess whether the detection of circulating tumor cells (CTC) could be used as a tool to earlier diagnose, more accurately predict treatment response / failure and predict overall survival in non-small cell lung cancer (NSCLC) patients

This trial will assess the incidence of new and/or undiagnosed diabetic macular edema (DME) in diabetic patients that undergo a DME screening exam. The screening exam will consist of medical history, Electronic ETDRS visual acuity assessment, SD-OCT and color fundus photography

The purpose of this study is to examine the body-fluid balance in patients with retinal vascular occlusion and the influence of drinking habits and hemodilution on the degree of body hydration.

With the far infrared ray applied to the 'phantom limbs' in amputees and the corresponding normal legs in healthy subjects, the sensation of (phantom) limb will be assessed for each subject using the techniques of fMRI and meridian response.

Neuroblastic tumors are childhood neoplasms that possess amino acid decarboxylase (AADC) activity and Meta-iodobenzylguanidine(MIBG), they can theoretically be imaged by (18)F-fluorodihydroxyphenylalanine ((18)F-FDOPA) and (123)I-Meta-iodobenzylguanidine((123)I-MIBG) PET, they are new and specific diagnostic and follow-up tools for neuroendocrine tumors. In this study, we explored the accuracy and clinical role of (18)F-FDOPA and (123)I-MIBG PET in neuroblastic tumors. METHODS: Patients with tissue-proven neuroblastic tumors receiving (18)F-FDOPA PET or (123)I-MIBG at initial diagnosis or during follow-ups were enrolled. The sensitivity and specificity of (18)F-FDOPA or (123)I-MIBG PET were compared to each other and compared to(18)F-FDG PET, using tumor histology as the standard.

The current protocol desires to implement a large-multicenter observational study of hospital acquired infection in ICU in China. The study will generate data on generate data about the epidemiology current management of nosocomial infection.

Heart failure and stroke are the two major complication of atrial fibrillation. Current treatment for atrial fibrillation is so focused to stroke prevention, but the risk assessment for heart failure is less highlighted. The most of patients with atrial fibrillation have cardiac functional limitation of variable degree. We hypothesize that the exercise test would reveal the subclinical cardiac dysfunction, and might be helpful to classify the patients with atrial fibrillation according to their exercise capacity real cardiac function.

MIND-TIA is primarily an observational diagnostic study that aims to evaluate the role of novel biomarkers in the diagnosis of Transient Ischemic Attack (TIA)in primary care. Rapid and adequate diagnosis of TIA is of great importance to enable a rapid start of treatment, and thereby decrease the risk of subsequent ischemic stroke.
