Cognitive Impairment in Ageing People
Mild cognitive impairment (MCI) and neurocognitive disorder such as Alzheimer's disease (AD) and Vascular dementia (VaD) have become common diseases in the elderly. The burden of dementia is rising in China, with major medical, social and economic impacts. To address this important public health problem, cohort study on elderly cognitive …
Minimal Invasive Axillary Staging and Treatment After Neoadjuvant Systemic Therapy in Node Positive Breast Cancer
Today, the majority of clinically node positive (cN+) breast cancer patients is treated with neoadjuvant systemic therapy (NST). Axillary staging and treatment after NST in cN+ patients are areas of controversy. Patients with a pathological complete response (pCR) of the axillary lymph nodes are not expected to benefit from axillary …
Data Collection for the Assessment of Acute and Late Normal Tissue in Patients Treated With Proton Therapy
This study collects information on the side effects of proton therapy and detailed information on the proton therapy treatment plan itself. This may help researchers develop methods to predict the risk of side effects for future patients and learn the long-term benefit of proton therapy.
Rare Tumours in Children and Adolescents (STEP)
The aim of the STEP registry is to collect and evaluate experience and data on the diagnosis and treatment of rare childhood tumors in order to use the knowledge gained to improve the treatment prospects for our patients. The rarity of a disease should not be a disadvantage for the …
Integrated Diagnostics for Early Diagnosis of Liver Disease
This is an observational study that will explore the hypothesis that by combining data from patients with liver disease with novel blood biomarkers, single nucleotide polymorphism (SNP) analysis and faecal microbiome analysis. The Investigators will improve diagnosis of liver fibrosis compared to the current available diagnostic tools.
Evaluating Efficacy and Safety of 1-year of DAPT After Genoss DES Sirolimus-eluting Stent Implantation in Patients
In this prospective, multicenter observational study, The investigators evaluated the safety and effectiveness of DAPT over 1 year in all patients with coronary artery disease, including patients with complex high-risk coronary artery disease (CHIP), who underwent PCI using the Genoss DES stent, and performed subgroup analysis. Through this, the investigators …
Leipzig Adipose Tissue Childhood Cohort
In this study the investigators hypothesize that pathological alterations in adipose tissue biology already occur during the development and progression of obesity in children and adolescents. The investigators aim to identify and characterize mechanisms and molecular targets that affect the development of adipose tissue and ensuing obesity in childhood and …

The Genetics of Polycystic Ovarian Syndrome
The goal of this study is to determine the genetic basis of polycystic ovary syndrome (PCOS). We will first look for genes in the Icelandic population, where large family trees are known and it is easier to search for genes. We will then determine whether these same genes are important …
