AI Article Synopsis
- The study aimed to identify age-specific normative values for whole-body sagittal alignment (WBSA) and global balance parameters in healthy adults, utilizing data from three international centers.
- A total of 317 healthy subjects, aged 20-84, were examined using biplanar X-ray imaging, assessing various spinopelvic and alignment parameters to understand age-related changes and correlations.
- Findings revealed significant age-related increases in local parameters like the C2-7 angle and knee flexion, while changes in global parameters linked to center of gravity were mild, indicating a compensatory mechanism within lower limbs was at play.
Article Abstract
Purpose: To investigate the age-specific normative values of whole-body sagittal alignment (WBSA) including global balance parameters in healthy adults and to clarify the correlations among parameters based on the data from three international multicenter.
Methods: Three hundred and seventeen healthy subjects (range: 20-84 y.o., mean: 43.8 ± 14.7 y.o.) were included and underwent whole-body biplanar X-ray imaging system. Spinopelvic parameters and knee flexion (KF), the center of acoustic meatus (CAM)-hip axis (HA), and C2 dentiform apophyse (OD)-HA, the cranial center (Cr)-HA were evaluated radiologically. Sub-analysis for correlation analysis between age and parameters and among parameters was performed to investigate age-specific change and compensatory mechanisms.
Results: For age-related change, C2-7 angle (r = .326 for male/.355 for female), KF (r = .427/.429), and SVA (r = .234/.507) increased with age in both male and female group. For global parameters related to the center of the gravity, correlations with age were not significant (r = .120/.161 for OD-HA, r = .163/.275 for Cr-HA, r = .149/.262 for CAM-HA). Knee flexion (KF) has correlation with global parameters (i.e., SVA, OD-HA, Cr-HA, CAM-HA) and does not have correlations with local spinopelvic alignment.
Conclusion: While several local alignment changes with age were found, changes in global parameters related to the center of gravity were kept relatively mild by the chain of compensation mechanisms including the lower limbs. We showed the normative values for a comprehensive WBSA in standing posture from large international healthy subjects' database.

Objectives: This research aims to validate the digits-in-noise (DIN) test for the Italian language and develop a version capable of independently assessing both ears while maintaining acceptable administration times.
Methods: Individual digits from 0 to 9 in Italian were recorded and adjusted to equalise recognition probabilities. An iOS application (APP) was developed for the independent ear test using triplets in noise.

Normative Palatal Measurements in Infants: Implications for Nasoalveolar Molding in Cleft Lip and Palate Patients.

Background: Children with cleft lip ± palate (CL/P) may undergo nasoalveolar molding (NAM) before surgery to achieve arch alignment and tension-free closure, yet the endpoint of arch dimensions has not been defined.
Objective: To characterize the size and shape of infant palates using anatomic landmarks on magnetic resonance imaging in infants without CL/P.
Methods: Magnetic resonance imaging of infants without cleft palate younger than 3 months were reviewed and 13 measurements were taken to define palatal shape: distance between incisive foramen (IF) and incisors (IN), IF and middle of canines (MOC), between MOCs, between first molars (FM), 2 depth and 4 angle measurements.
E-norms and AI in clinical neurophysiology.

Department of Public Health and Community Medicine, Tufts University School of Medicine, Boston, MA, United States.
Objective: To describe the use of Artificial Intelligence (AI) to automate the e-norms method, a technique used to derive normative data from patient studies, mixed datasets that contain both normal and abnormal data. Multiple studies have shown that normal values collected with the e-norms method compare favorably with those collected from healthy volunteers using traditional methods.
Methods: OpenAI's ChatGPT was used by the author to build a Python script to automate the e-norms method's plateau identification, the area of the e-norms curve where a variable's normal values lie.

Background: Many studies have examined the prevalence of acetabular version (AV) and femoral version (FV) abnormalities and their effect on patient-reported outcomes (PROs) after hip arthroscopy for femoroacetabular impingement syndrome (FAIS), but few have explored the prevalence and influence of combined version (CV) abnormalities.
Purpose: To (1) describe the distribution of AV, FV, and CV in the largest cohort to date and (2) determine the relationship between AV, FV, and CV and PROs after hip arthroscopy for FAIS.
Study Design: Cohort study; Level of evidence, 3.
