Pleth Variability Index and Hypotension

HypotensionPleth Variability Index

Correct assessment of a patient's volume status is the most important goal for an anesthetist. However, most of the variables used for fluid response evaluation are invasive and technically challenging.Pulse oximeter is a non-invasive, standardized and widely used monitoring method in many countries. Our aim in this study is to investigate the usefulness of the noninvasive pleth variability index to predict hypotension in orthopedic hip fracture patients who underwent spinal anesthesia.

Using 16S rRNA Gene Sequencing Analysis Intestinal Microbiota in Constipation Patients

Slow Transit Constipation

Constipation is a frequent, chronic gastroenterological problem that has many varied symptoms and thus has several clinical definitions. According to the Rome III criteria for chronic constipation, almost 16% of all adults are affected by chronic constipation worldwide, and it is more prevalent and symptomatic in women and elderly people. Slow transit constipation (STC) is the major category and is characterized by a decreased rate of colonic transit. Recently, many researchers have focused on the relationship between intestinal microbiota and constipation and have demonstrated that intestinal microbiota contribute to the pathophysiology of functional gastrointestinal disorders. Thus, there is a need for an improved understanding of gut microbiota composition in constipation patients and for the potential role played by the gut microbiota in the etiology of STC.To achieve this goal the investigators characterized and compared the intestinal microbiota among carefully selected patients with constipation that were clinically categorized based on Rome III criteria, and healthy controls using high throughput pyrosequencing of the 16S rRNA gene and a conservative approach to detect quantitative changes in the relative abundances of taxa.

The Epidemiology of Recurrent Spontaneous Abortion Associated With Thrombophilla

Recurrent Pregnancy Loss

RSA is a multifactorial disorder resulting from genetic factors, anatomic factors, autoimmune disorders, endocrine dysfunction, thrombophilia, life style factors, and maternal infections. However, the underlying causes remain undetermined in up to 50% of cases. In this clinical cohort study, we intended to get an epidemiological evidence for patients with recurrent spontaneous abortion associated with thrombophilla.

Research on Pathophysiology and Treatment in Depression Using Brain Derived Neurotrophic Factor...

Major Depressive Disorder

Target of the research Based on change of Brain-derived neurotrophic factor and other pro-inflammatory cytokine along with symptom improvement following treatment, the investigators are trying to find the new treatment target molecule. The investigators will follow up the subjective and objective cognitive dysfunction with psychiatric symptom profiles and compare the neuroimaging related to these change.

Continous Assessment of Cerebral Autoregulation With Near-infrared Spectroscopy

Cerebral Blood FlowCerebral Perfusion Pressure

Cerebral autoregulation can be explained by a tight coupling between oxygen supply and demand of the brain, and is essential to maintain a constant cerebral blood flow (CBF) in the context of changes in cerebral perfusion pressure. In this study, investigators use Near-infrared spectroscopy (NIRS) to monitor cerebral autoregulation.
