AI Article Synopsis
- Computational musculoskeletal modeling enhances our understanding of upper extremity biomechanics when physical testing is not possible.
- A new model was developed that incorporates humeral head translation and ligaments, improving its biofidelity.
- The model showed that the humerus moves upward with increased shoulder elevation, and its accuracy closely aligns with previous studies, suggesting it can better predict upper limb movements and help analyze conditions like shoulder injuries.
Article Abstract
Computational musculoskeletal modeling is useful for understanding upper extremity biomechanics, especially when tests are unfeasible. A musculoskeletal model of the upper limb with increased biofidelity was developed by including humeral head translation (HHT) and ligaments. The model was validated and ligament contribution and effect of shoulder (thoracohumeral) elevation on HHT was evaluated. Humerus translated superiorly with increased elevation, with translations closely matching (avg. difference 2.83 mm) previous studies. HHT and ligament inclusion in the model will improve biomechanical predictions of upper extremity movements and study of conditions, like subacromial impingement, rotator cuff tear, or shoulder instability.

Objective: To investigate the biodynamics of human-exoskeleton interactions during patient handling tasks using a subject-specific modeling approach.
Background: Exoskeleton technology holds promise for mitigating musculoskeletal disorders caused by manual handling and most alarmingly by patient handling jobs. A deeper, more unified understanding of the biomechanical effects of exoskeleton use calls for advanced subject-specific models of complex, dynamic human-exoskeleton interactions.
A NOTCH3 pathogenic variant influences osteogenesis and can be targeted by antisense oligonucleotides in induced pluripotent stem cells.

Lateral Meningocele Syndrome (LMS), a disorder associated with NOTCH3 pathogenic variants, presents with neurological, craniofacial and skeletal abnormalities. Mouse models of the disease exhibit osteopenia that is ameliorated by the administration of Notch3 antisense oligonucleotides (ASO) targeting either Notch3 or the Notch3 mutation. To determine the consequences of LMS pathogenic variants in human cells and whether they can be targeted by ASOs, induced pluripotent NCRM1 and NCRM5 stem (iPS) cells harboring a NOTCH36692-93insC insertion were created.

Purpose: This study aimed at comparing the costs of spinal fusion surgery between patients with and without diabetes.
Methods: Following PRISMA guidelines, a systematic search of four databases was conducted. A meta-analysis was performed on comparative studies examining diabetic versus non-diabetic adults undergoing cervical/lumbar fusion in terms of cost.
Comprehensive epidemiology of melanoma at all sites: insights from Japan's National Cancer Registry, 2016-2017.

Rare Cancer Center, National Cancer Center, Tokyo, Japan.
Background: Melanoma is a highly malignant cancer responsible for 55 000 deaths worldwide annually. Despite its severity, its epidemiology in Japan remains understudied owing to its rarity among Asians. This study aimed to determine the incidence of melanoma in Japan using data from the National Cancer Registry.

: Stigma in amyotrophic lateral sclerosis/motor neurone disease (ALS/MND) may be felt or enacted; felt stigma covers feeling devalued by the illness, whereas enacted stigma refers to being treated differently because of it. Stigma in ALS/MND has been shown to increase social withdrawal, worsen quality of life, and reduce use of assistive devices, so we explored prevalence and factors influencing stigma. : Participants in the Trajectories of Outcome in Neurological Conditions-ALS study completed scales measuring stigma, fatigue, spasticity, functioning, mood, worry, self-esteem, and perceived health, as well as demographic information and symptoms like head drop or emotional lability.
