More than 20% of patients over 60 years old develop postoperative delirium following non-cardiac surgery . Delirium increases morbidity and mortality , and may lead to long-term cognitive impairment . The underlying mechanisms behind delirium are not understood , endothelial dysfunction and disruption of the blood brain barrier (BBB ) caused by perioperative systemic inflammation may play a important role in the development of delirium . This study intends to evaluate the relationship between neuroinflammation and postoperative delirium in elderly non-cardiac surgery patients . The results of the study are to identify risk factors and explore the biomarkers most closely linked to each step of the proposed pathway .

To develop and validate a questionnaire aiming at assessing specific activity limitation in patients with lumbar spinal stenosis (LSS).

Perivascular epithelioid cell tumors are rare and characterized by the expression of myomelanocytic markers. They belong to a complex tumor family that includes angiomyolipomas, lymphangioleiomyomatosis and other soft-tissue tumors. Given their rarity, the natural history of pecomas is not yet understood, and a comprehensive classification that integrates clinical, pathological and molecular features has not been achieved as of today. This study is a national multicenter retrospective study to better understand the natural history of PEComas, excluding lymphangioleiomyomatosis and classic triphasic angiomyolipomas. The primary purpose is the identification of prognostic markers impacting the relapse. Secondaries purposes are to identify prognostic markers impacting the overall survival and to have a better understanding of natural history

Contraception is an important issue in public health; especially when maternal risks and morbidities are considered. There is a need for consciousness about the contraceptive choices. The reproductive age women in Turkey may be stubborn or may choose to believe heath information. The oral contraceptive drugs are not used because of wrong beliefs.

The investigators aim to study the population pharmacokinetics of children receiving the anti-infective drugs for treatment of infectious disease in central nervous system.

Allogenic HSCT brings significant changes in biodiversity and composition of the gut microbiome through antibiotic usage, the mucosal damage due to the chemo- and radiotherapy toxicity; compromised oral nutritional intake and graft-versus-host disease with gut damage as the complication. Aim of the study is to investigate the composition of the microbiota in both recipient and nursing relative donor, reveal changes in biodiversity after HSCT via 3-time points V3V4 16S rRNA and NGS sequencing of the colon and oral swabs, 3-indoxyl-sulfate measurement in the urine.

This observational cohort study is aimed at determining changes in the cytokine expression profile as well as the urinary and vaginal microbiome of women undergoing midurethral sling placement for the treatment of stress urinary incontinence.

This study focuses on advanced lung and head and neck SCC tumours, with adjacent normal lung tissues. Biopsies will be performed in National University Health System, Singapore (NUHS) as part of participants' standard care. Patient blood was also required for extraction of cell free DNA (cfDNA) and genomic DNA (gDNA). Patients' medical records will also be reviewed for the purpose of this study.
