Circular RNAs in the management of human osteoporosis.

Background: Osteoporosis (OP) is a metabolic bone disease producing reduction in bone mass with consequent bone fragility. Circular ribonucleic acid (CircRNA) is a form of RNA that forms a loop structure rather than a linear one. CircRNA can be used for therapeutic purposes, including molecular targets or to test new therapies.

ColMA-based bioprinted 3D scaffold allowed to study tenogenic events in human tendon stem cells.

The advent of bioprinting has enabled the creation of precise three-dimensional (3D) cell cultures suitable for biomimetic in vitro models. In this study, we developed a novel protocol for 3D printing methacrylated collagen (ColMa, or PhotoCol®) combined with tendon stem/progenitor cells (hTSPCs) derived from human tendon explants. Although pure ColMa has not previously been proposed as a printable hydrogel, this paper outlines a robust and highly reproducible pipeline for bioprinting this material.

Augmentation with the inferior extensor retinaculum may facilitate earlier recovery in all-inside arthroscopic management of chronic lateral ankle instability.

Background: To compare the clinical outcomes of inferior extensor retinaculum (IER) augmentation following repair of the anterior talofibular ligament (ATFL) with isolated ATFL repair in patients with an arthroscopically confirmed grade 3 lesion of the ATFL.

Methods: We conducted a retrospective study of consecutive chronic lateral ankle instability (CLAI) patients who underwent arthroscopic ATFL repair between March 2018 and August 2022. The average age of the patients was 31.

Machine Learning-Driven Prediction, Preparation, and Evaluation of Functional Nanomedicines Via Drug-Drug Self-Assembly.

Lewinnek zone not "the be-all and end-all" functional planning for acetabular component positioning in total hip arthroplasty.

Background: Proper positioning of a total hip arthroplasty (THA) plays a crucial role in the success and long-term survivorship of the implant. Cup positioning within the Lewinnek Safe Zone (LSZ) does not, however, avoid implant dislocation. Thus, the concept of a functional cup position has been introduced.

A systematic analysis of the global, regional, and national burden of fungal skin diseases from 1990 to 2021.

Purpose: We aimed to assess the burden of Fungal Skin Diseases (FSD) in 2021 and explore the changing trends from 1990 to 2021 across different age groups and time periods.

Methods: This study extracted three key indicators of the burden of FSD from the Global Burden of Disease (GBD) 2021 study: prevalence, incidence, and disability-adjusted life years (DALYs). The results were presented using point estimates and Uncertainty Intervals (UIs), and secondary analysis was conducted on these data to assess the changing trends in the burden of FSD using percentage change.

Characteristics of biofilm layer in a bio-doubling reactor and their impact on aerobic denitrifying bacteria enrichment.

Microbial loss significantly affects wastewater treatment efficiency. This study simulated the inoculation area of a self-developed biological doubling reactor (BDR) to evaluate the retention efficiency of seven different fillers for aerobic denitrifying bacteria. Over 90 days of continuous operation, the porous filler R3 demonstrated excellent performance, with OD values consistently exceeding 1.

A novel electrochemical immunosensor for the ultrasensitive detection of vascular endothelial growth factor based on MB@Cu-MOFs/MWCNTs composite.

A novel proposal is introduced with an unlabeled electrochemical immunosensor for the detection of tumor broad-spectrum biomarker vascular endothelial growth factor (VEGF165) Copper-based metal organic frameworks (Cu MOFs)-carbon nanotubes (MWCNTs) were employed as its substrates, functionalized with methylene blue (MB) for signal enhancement. Cu-MOFs-MWCNTs nanocomposites were synthesized successfully via a solvothermal method and were then deposited on the surface of a glassy carbon electrode (GCE), with the addition of methylene blue to amplify the signal. Due to the expansive specific surface area provided by the carbon nanotubes and the amino groups facilitated by the metal-organic framework nanomaterials, the anti-VEGF165 monoclonal antibody was immobilized on the electrochemical immunosensor through covalent bonding, which could bind specifically to VEGF165, thereby causing a detectable change in the current.

Molecular Mimicry Between Gut Microbiome and Rheumatoid Arthritis: Current Concepts.

Rheumatoid arthritis (RA) represents an autoimmune condition impacted by a combination of genetic and environmental factors, with the gut microbiome (GMB) being one of the influential environmental factors. Patients with RA display notable modifications in the composition of their GMB, characterised by decreased diversity and distinct bacterial alterations. The GMB, comprising an extensive array of approximately 35,000 bacterial species residing within the gastrointestinal tract, has garnered considerable attention as a pivotal contributor to both human health and the pathogenesis of diseases.

Everyday living with osteoarthritis in the global South: A qualitative focus group inquiry in Nigeria.

Objective: Africa contributes significantly to the increasing global prevalence (>37 ​%), unmet need and treatment burden for people with osteoarthritis. Despite this, little research has examined the expressed needs of patients with osteoarthritis (OA) and joint pain in West-Africa. This study aimed to explore lived experiences, expressed needs and current care gaps for people living with osteoarthritis in low-health resource contexts using Nigeria as a case study.

Evaluating the use of electromyography in UK and European gait laboratories for the assessment of cerebral palsy and other neurological and musculoskeletal conditions.

Background: Electromyography (EMG) can estimate the magnitude and timing of muscle activation during walking in those with gait disorders. Despite the potential of EMG use in assessment and clinical decision-making, there are reports of declining use of EMG within gait laboratories. Technical and educational barriers to EMG usage in clinics in Italy were recently suggested.

The ligamentum teres and its role in hip arthroscopy for femoroacetabular impingement: a systematic review.

Background: The ligamentum teres (LT) has received attention in patients undergoing hip arthroscopy (HA) for femoroacetabular impingement (FAI). Indeed, a better understanding of the function of the LT and its implications for clinical outcomes in the presence of a torn LT is required. This systematic review analyses the patient-reported outcome measures (PROMs) and the complication rate when an intact or torn LT is encountered during HA for FAI.

Chia seed supplementation and inflammatory biomarkers: a systematic review and meta-analysis.

Chia seeds have gained attention for their potential anti-inflammatory properties, which may be attributed to their high content of omega-3 fatty acids, dietary fibre, and antioxidants. This study aims to provide an overview of the current understanding regarding the effects of chia seeds on inflammatory markers, specifically C-reactive protein (CRP), interleukin-6 (IL-6), and tumour necrosis factor-alpha (TNF-α). A comprehensive literature search was conducted on PubMed, Scopus, Web of Science, Cochrane, and Google Scholar up to June 2024.

Arthroscopic lateral ligament reconstruction for isolated chronic lateral ankle instability is associated with longer recovery compared to arthroscopic Broström repair and inferior extensor retinaculum augmentation.

Background: Patients with chronic lateral ankle instability (CLAI) can be managed with arthroscopic Broström repair and inferior extensor retinaculum augmentation or arthroscopic assisted lateral ligament reconstruction using ipsilateral semitendinosus autograft, with good functional outcomes in patients. It is unclear whether one offers better outcome that the other. This retrospective analysis of prospectively collected data compared the outcomes of repair and reconstruction.

The clinical potential of meniscal progenitor cells.

Introduction: The meniscus is an important cushioning structure of the knee joint, with the maintenance of its normal structure and function playing a crucial role in protecting the joint from early degeneration. Stem/progenitor cells could be the key to help researchers to have a deeper understanding of the biological process of meniscal injury repair and may be important in the meniscus tissue regeneration processes. To the best of our knowledge, there is currently a lack of comprehensive reviews on existing research about the meniscus progenitor cells (MPCs).
