The Developing Belief Network is a global research collaborative studying religious development in diverse social-cultural settings, with a focus on the intersection of cognitive mechanisms and cultural beliefs and practices in early and middle childhood. The current manuscript describes the study protocol for the network's second wave of data collection, which aims to further explore the development and diversity of religious cognition and behavior using a multi-time point approach. This protocol is designed to investigate three key research questions-how children represent and reason about religious and supernatural agents, how children represent and reason about religion as an aspect of social identity, and how religious and supernatural beliefs are transmitted within and between generations-via a set of eight tasks for children between the ages of 5 and 13 years and a survey completed by their parents/caregivers.

Lateral approach for total knee arthroplasty in patients with valgus deformity: A step-by-step surgical technique.

SICOT J

September 2025

Orthopaedics Surgery and Sports Medicine Department, FIFA Medical Center of Excellence, Croix-Rousse Hospital, Hospices Civils de Lyon, Lyon North University Hospital, 103 Grande Rue de la Croix-Rousse, 69004 Lyon, France - Univ Lyon, Claude Bernard Lyon 1 University, IFSTTAR, LBMC UMR_T9406, 25 Ave

Background: The lateral approach in total knee arthroplasty (TKA) is indicated primarily for patients with valgus knee deformity, as it allows direct access to the lateral anatomy and systematic correction of associated pathologies.

Surgical Technique: This technique involves strategic lateral soft tissue releases, which improve exposure to the posterolateral corner, enhance tibial rotation, and support patellar alignment without compromising medial vascularity or requiring a tibial tubercle osteotomy for joint exposure. Critical steps in the lateral TKA approach include maintaining a capsular-synovial overlap and preserving the Hoffa fat pad for optimal joint closure, releasing the lateral soft-tissue structures, and using a contralateral tibial cutting guide for enhanced access and protection of the patellar tendon.

Department of Orthopaedics Surgery and Sports Medicine, FIFA Medical Center of Excellence, Croix-Rousse Hospital, Lyon University Hospital, Hospices Civils de Lyon, Lyon, France.

Purpose: Functional knee positioning (FKPos) in total knee arthroplasty (TKA) optimises outcomes by balancing individual anatomical and soft tissue characteristics. Managing marked varus deformity presents challenges in achieving balance when tibial alignment is restricted to 3° of varus, necessitating either medial soft tissue release or unrestricted tibial positioning. This study aims to compare restricted FKPos with medial soft tissue release to unrestricted FKPos without soft tissue release in patients with varus deformity ≥10°.

Transcriptional enhancers are DNA regulatory elements that control the levels and spatiotemporal patterns of gene expression during development, homeostasis, and pathophysiological processes. Enhancer identification and characterization at the genome-wide scale rely on their structural characteristics, such as chromatin accessibility, binding of transcription factors and cofactors, activating histone modifications, 3D interactions with other regulatory elements, as well as functional characteristics measured by massively parallel reporter assays and sequence conservation approaches. Recently, machine learning approaches and particularly deep learning models (Enformer, BPNet, DeepSTARR, etc.

: Neurodevelopmental disorders, including autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD), are increasingly recognized as conditions arising from multifaceted interactions among genetic predisposition, environmental exposures, and epigenetic modifications. Among epigenetic mechanisms, non-coding RNAs (ncRNAs), including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and PIWI-interacting RNAs (piRNAs), have gained attention as pivotal regulators of gene expression during neurodevelopment. These RNA species do not encode proteins but modulate gene expression at transcriptional and post-transcriptional levels, thereby influencing neuronal differentiation, synaptogenesis, and plasticity.

Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) is one of the fastest-growing hepatic disorders worldwide. During its natural course, MASLD tends to progress from isolated steatosis of the liver to Metabolic Dysfunction-Associated Alcoholic Steatohepatitis (MASH), advanced fibrosis, and finally cirrhosis, with the risk of developing hepatocellular carcinoma (HCC). Although frequently related to overweight or obesity and other components of the metabolic syndrome (MS), MASLD can also be present in individuals without such risk factors.
