Correlation between heart rate variability and perioperative neurocognitive disorders in patients undergoing non-cardiac surgery: A retrospective cohort study.

Objective: With the improvement of medical level, the number of elderly patients is increasing, and the postoperative outcome of the patients cannot be ignored. However, there have been no studies on the relationship between preoperative heart rate variability (HRV) and Perioperative Neurocognitive Disorders (PND). The purpose of this study was to explore the correlation between (HRV) and (PND), postoperative intensive care unit (ICU), and hospital stay in patients undergoing non-cardiac surgery.

Comparison of the femoral condylar ellipse line and the surgical epicondylar axis: 3D measurement by MRI scans in healthy Chinese people.

Objective: The sagittal shapes of the femoral condyles were thought to consist of circles. However, the line connecting the centers of circles was not consistent with the surgical epicondylar axis (SEA) which was commonly used in surgery. Recently, ellipses have been proposed as an alternative method to represent the sagittal femoral condylar shape.

Relationship between Heart Rate Variability and Postoperative Cognitive Dysfunction in Elderly Patients.

Postoperative cognitive dysfunction (POCD) is objectively measurable after anesthesia and surgery. Lower heart rate variability (HRV) is associated with poorer cognitive performance, but the relationship between HRV and POCD remains unclear. Elderly patients who underwent total hip replacement under general anesthesia from the Department of Bone and Joint Surgery, Affiliated Hospital of Southwest Medical University were enrolled.

Dimensional Changes of Lumbar Intervertebral Foramen in Direct Anterior Approach-Specific Hyperextension Supine Position.

Objective: To investigate the changes in the lumbar intervertebral foramen (LIVF) dimensions from neutral supine to direct anterior approach (DAA)-specific hyperextension supine position through a standardized three-dimensional (3D) reconstruction computerized tomography (CT) method.

Methods: A total of 35 healthy volunteers (18 men and 17 women) were included in this retrospective study. The mean age of enrolled subjects was 28.

Three-point Method to Guide the Tibial Resection and Component Placing in Total Knee Arthroplasty.

Objective: To introduce a three-point method combining the midpoint of the posterior cruciate ligament (PCL), the midsulcus of the tibial spines, and the midpoint of the anterior cruciate ligament (ACL) to determine appropriate tibial resection and component placing during TKA and to compare this method with Insall's 1/3 method.

Methods: A consecutive series of 128 knees that underwent TKA from January 2015 to August 2018 were analyzed. In one group (64 knees), the medial 1/3 of tibial tubercle (the Insall's traditional method) was used for tibial component alignment.

The relationship between the posterior tibial slope and the sagittal femoral condylar shape: Two circles and ellipses.

Background: Whether the posterior tibial slope (PTS) is associated with the femoral condylar shape has remained unclear. Classical anatomical studies considered the sagittal profiles of femoral condyles to consist of two circles. Recently, an elliptical method was described to simplify the "two circles" model.

A simplified relationship between the femoral trochlea and the femoral condyle: A sagittal MRI analysis by an ellipse-fitting approach.

We have introduced an ellipse-fitting approach to express the shapes of trochlea and condyle on magnetic resonance imaging (MRI) and to analyze their relationship. Fifty healthy right knees were sagittal-imaged by MRI at full extension. On the deepest trochlear groove slice, the articular surface was best-fitted by a circle.

Serum glial cell line-derived neurotrophic factor levels and postoperative cognitive dysfunction after surgery for rheumatic heart disease.

Objective: Postoperative cognitive dysfunction is an important complication of cardiac surgery with poor outcomes. Serum glial cell line-derived neurotrophic factor levels are decreased in patients with Alzheimer's disease, but the association between glial cell line-derived neurotrophic factor levels and postoperative cognitive dysfunction is poorly understood. The present study aimed to investigate the prognostic value of postoperative serum glial cell line-derived neurotrophic factor levels to predict postoperative cognitive dysfunction in patients with rheumatic heart disease undergoing heart valve replacement.

Elevated Serum and Cerebrospinal Fluid Free Fatty Acid Levels Are Associated with Unfavorable Functional Outcome in Subjects with Acute Ischemic Stroke.

The aim of this study was to evaluate the prognostic value of serum and cerebrospinal fluid (CSF) free fatty acid (FFA) levels in a cohort of patients with an acute ischemic stroke (AIS). In a prospective study, FFA levels were measured using an enzyme cycling method on admission in serum and CSF of 252 consecutive patients with AIS. The prognostic value of FFA to predict the functional outcome and mortality within 90-day was compared with the National Institutes of Health Stroke Scale score and with other known outcome predictors.

The diagnostic and prognostic value of serum CXCL12 levels in patients with ischemic stroke.

The aim of this study was to investigate the potential diagnostic and prognostic role of CXC chemokine ligand-12 (CXCL12) in Chinese patients with acute ischemic stroke (AIS). All consecutive patients with first-ever AIS from January 2014 to August 2014 were recruited to participate in the study. CXCL12 and NIH Stroke Scale were measured at the time of admission.
