1 Serum Biomarkers for Prediction and Diagnosis of POCD in Elderly Patients Undergoing Cardiac Surgery.

Postoperative cognitive dysfunction (POCD) is a severe complication after surgery. Currently, a complicated battery of neuropsychological tests both before and after surgery with other characteristics-matched population as control are needed for the diagnosis of POCD. This diagnosis is also delayed, which could not be used to screen for high risk patients who may need intervention beforehand. The current trial targeted a surgical population of elderly patients undergoing cardiac surgery under cardiopulmonary bypass (CPB), which is a population of the highest incidence of POCD, to screen for possible predictive or diagnostic biomarkers in the serum for POCD. Myeloid differentiation factor 2 (MD2), also known as lymphocyte antigen 96, is a protein involved in biding lipopolysaccharide with Toll like receptor-4 (TLR4). Recently the investigators have found that increased MD2 expression in the hippocampus of the mice after surgery stimuli. On the other hand, the investigators have reported that cystatin C (CysC) as an endogenous neuroprotective factor for stroke. It may also be involved in endogenous neural protection against POCD. This trial is to investigate whether serum MD2, CysC can be used for prediction and diagnosis of POCD in surgical population. Serum based DNA methylation biomarkers will also be tested for prediction or diagnosis of POCD development. Also in our orevious research, SNPs cites at rs6739405、rs12467815、rs12472215、rs11126727、rs11126731、rs993607 were revealed as possible susceptibility variations for POCD (diagnosed with MMSE only, NCT02084030) in patients undergoing CPB. This study will also test the SNP variations in study populations to varify if one or conbination of morethan one of these varuations can be a risk factor for POCD when diagonosed with NPT.

NCT03610191 Postoperative Cognitive Dysfunction Diagnostic Test: Serum biomarker tests Behavioral: Neuropsychological battery tests Procedure: Cardiac surgery
MeSH:Cognitive Dysfunction
HPO:Cognitive impairment Mental deterioration

Also in our orevious research, SNPs cites at rs6739405, rs12467815, rs12472215, rs11126727, rs11126731, rs993607 were revealed as possible susceptibility variations for POCD (diagnosed with MMSE only, NCT02084030) in patients undergoing CPB.

Our previous clinical trial (NCT 02084030) indicates that, 6 SNP mutations on the CTNNA2 gene (SNPs cites at rs6739405, rs12467815, rs12472215, rs11126727, rs11126731, rs993607) has altered risk for POCD in elderly patients undergoing CPB.

Primary Outcomes

Description: Blood samples will be collected at immediately before anesthesia and tested for MD2/CysC/DAN Methylation marker value.

Measure: Preoperative serum MD2/CysC/DAN Methylation marker/SNPs mutation rates on CTNNA2 gene before anesthesia

Time: Immediately before anesthesia

Description: Blood samples will be collected at immediately after surgery and tested for MD2/CysC/DAN Methylation marker value.

Measure: Postoperative serum MD2/CysC/DAN Methylation marker/immediately after surgery

Time: Immediately after surgery

Description: Blood samples will be collected at 24h after surgery and tested for MD2/CysC/DAN Methylation marker value.

Measure: Postoperative serum MD2/CysC/DAN Methylation marker value at 24 h after surgery

Time: Twenty-four hours after surgery

Description: NPB will be evaluated at 3 time points: 1. one day before surgery. 2. one day before discharge. 3. 3 months after surgery. The NPB includes: 1. Grooved Pegboard Test; 2. Auditory Word Memory Test; 3. Trail Making Test (Part A, Part B); 4. Digit Span Test; 5. Digit Symbol Subtest; 6. Verbal Fluency Test; and 7. Word Recall Test. POCD at discharge or 3 months after surgery will be analyzed as follow: 2 or more tests of the NPB with a Z score over 1.96 or less than -1.96, patient is defined as POCD. And patients that have less than 2 tests with a Z score over 1.96 is defined as no-POCD. Note: the time frame of postoperative NPB test is defined as one day before discharge. It is usually within 5-9 days depending on the hospitalization time for each patient. Since NPB test is time consuming and requires patients at a comfortable state. The investigators chose one day before discharge as many clinical trials regarding POCD reported.

Measure: Neuropsychological battery (NPB) assessment

Time: From one day before surgery to 3 months after surgery
