Researchers will compare the I'M Walking program with a Walk With Ease program (self-directed program)

Efficacy & Safety of Fluoroquinolone-Based Brucellosis Regimens (BRUCE)

Brucellosis is a globally distributed zoonosis with persistent clinical management challenges. The World Health Organization(WHO)-recommended doxycycline-rifampin (DOX-RIF) dual regimen may drive rifampin-associated antimicrobial resistance across all brucellosis-endemic regions. Patients with osteoarticular brucellosis require long-term intravenous ceftriaxone triple therapy, which is linked to poor treatment adherence due to repeated hospital visits and outpatient care demands. Fluoroquinolones (levofloxacin \[LVX\], moxifloxacin \[MXF\]) exert excellent anti-Brucella activity and superior bone-joint penetration, yet high-quality multicenter prospective data comparing rifampin-sparing LVX-DOX/MXF-DOX dual regimens against standard RIF-DOX remain rarely reported. Existing comparative studies are limited to small single-center retrospective cohorts or trials pairing rifampin with fluoroquinolones rather than rifampin-free dual oral therapy. This multicenter prospective parallel-cohort protocol includes Module I (non-inferiority design) : 200 patients with uncomplicated acute brucellosis receiving 6-week dual oral therapy; and Module II (non-inferiority design) : 150 patients with imaging-confirmed osteoarticular brucellosis receiving 12-week triple therapy. Clinical data of standardized clinical, laboratory, radiologic, and subsequent longitudinal follow-up data will be collected via centralized electronic data capture. Primary endpoints include clinical and microbiological cure rates at 6 weeks (Module I) and 12 weeks (Module II). Secondary endpoints measure 24-week post treatment recurrence, 24- and 48-week radiologic improvement for osteoarticular disease, and adverse events during treatment. Multivariate regression and Cox models will identify independent prognostic factors and construct a generalizable recurrence risk prediction model. This clinical trial fills a critical evidence gap for oral fluoroquinolone-based regimens, with findings intended to supply supplementary brucellosis treatment approach, reduce rifampin resistance pressure, and eliminate reliance on prolonged parenteral therapy for complicated brucellosis. This original trial record (NCT07779629, BRUCE Study) has been split into two independent clinical trials focusing on different brucellosis phenotypes. The two separate trials have been registered individually: NCT07887126 for uncomplicated brucellosis and NCT07887152 for osteoarticular brucellosis. The original combined protocol is retired and will not be implemented further.

Generative AI Impact on Rheumatoid Arthritis Complications Diagnosis

Generative AI (GenAI) based on large language models (LLMs) is expected to improve the diagnosis and treatment of autoimmune diseases. We are studying how GenAI may affect the diagnosis of various complications of rheumatoid arthritis (RA). In a retrospective study using RA patients' EHR records, we will quantify physician adoption of GenAI predictions for RA complications and co-existing diseases. In a prospective observational study, we will assess the feasibility of using GenAI predictions as additional clinical information to help physicians make more complete diagnoses of RA complications and co-existing diseases, including complex, uncommon, or rare conditions.

Safety of Cultured Allogeneic Adult Umbilical Cord or Placental Derived Mesenchymal Stem Cells for OA

New Method of Surgical Treatment of Patients With Osteoarthritis of the 1st Metatarsophalangeal Joint

Relevance The first metatarsophalangeal joint (MPJ) has an important function in the biomechanics of human gait, especially in the toe and thrust phases, as the full range of motion at this joint provides the body with smooth horizontal acceleration. The flattening of the arches of the foot and, as a result, the overload of its anterior section occupy a leading place in the etiology of deforming osteoarthritis (Hallux rigidus). Hallux rigidus is a disease associated with degenerative changes in the articular cartilage of the first metatarsophalangeal joint. The relevance of the treatment of arthrosis of the first metatarsophalangeal joint is determined by the high incidence and functional significance of the joint. At the 3rd and 4th degrees of arthrosis, arthrodesis, resection arthroplasty and arthroplasty of the first metatarsophalangeal joint are used. To date, the most optimal methods of surgical treatment of severe arthrosis of the first metatarsophalangeal joint are arthroplasty and arthrodesis of the joint. These operations are preferred because they achieve good clinical and radiological results. Long-term follow-up studies are needed to confirm the current findings. Uncoupled endoprostheses are characterized by satisfactory mobility, the ability to withstand high loads, and ligament structures are preserved during their implantation. Of the existing types of non-bonded endoprostheses, zirconium ceramics has a number of advantages, such as: good ingrowth ability, no wear, no rejection reactions. The main advantages of this type of surgical treatment are: rapid pain relief, improved function and stability, individual adaptation of prostheses. Endoprosthetics is recommended for patients of working age with high functional demands. Thus, the development and implementation of new design solutions in clinical practice is relevant and promising. task in the surgical treatment of patients with deforming osteoarthritis of the first metatarsophalangeal joint. Purpose of the study: To develop and introduce into clinical practice a new method of surgical treatment of patients with deforming osteoarthrosis of the first metatarsophalangeal joint using an anatomically adapted endoprosthesis.

E-Type - Early Wear of Polyethylene Liners Used in DMC

This is a single-centre, randomized, double-blinded controlled non-inferiority trial that will be conducted at the Orthopaedic Department at Uppsala University Hospital, Uppsala. The aim of the study is to evaluate the performance of a dual mobility acetabular component with a Vitamin E-infused highly crosslinked polyethylene (VEPE) liner compared to a conventional polyethylene (PE) liner in adult patients with symptomatic osteoarthritis, osteonecrosis, or dysplasia of the hip requiring a hip replacement. The assessments will focus on early wear, cup migration, adverse events, and clinical outcomes. Measurements will be conducted using Computed Tomography Radiostereometric Analysis (CT-RSA) instead of traditional radiostereometric analysis. The study hypothesis is that the PE liner will be non-inferior to the VEPE liner in terms of early wear over a two-year period.

The Effect of Continuous Care Counseling Based on the Roy Adaptation Model on Comfort and Quality of Life in Patients Undergoing Total Knee Arthroplasty

Osteoarthritis is a common joint disease that leads to problems such as pain, restricted mobility, and decreased quality of life in the knee joint, especially among elderly individuals. In advanced-stage knee osteoarthritis, total knee arthroplasty (TKA) is performed to reduce pain and loss of function. However, in the postoperative period, patients may encounter various problems such as pain, sleep disturbances, anxiety, and difficulties in daily living activities. This study investigates how continuous care counseling based on Roy's Adaptation Model affects the comfort and quality of life of patients undergoing total knee arthroplasty. Roy's Adaptation Model is a widely used approach in nursing that supports individuals in adapting to changes they experience. Counseling and education provided in line with this model aim to help patients cope with the physical and psychological problems they face before and after surgery. In the study, specially designed training and counseling services were provided to patients undergoing surgery, and the effects of these interventions on comfort and quality of life were evaluated. The study aims to contribute to the enhancement of postoperative care practices and patient-centered nursing interventions for individuals undergoing total knee arthroplasty.

This is a prospective, multi-center, non-randomized, non-controlled study designed to obtain survival and outcome data on the Continuum Metal on Polyethylene Acetabular System when used in primary total hip arthroplasty.

Preoperative Music Intervention for Anxiety in Hip and Knee Arthroplasty

Many patients feel anxious before joint replacement surgery. This anxiety is common - affecting roughly 1 in 3 patients - and research has shown that patients who are more anxious before surgery tend to have more pain afterward and may need more pain medication during recovery. Listening to music before medical procedures has been shown to reduce anxiety in many types of surgery. In fact, a recent analysis of 20 studies found that music works about as well as anti-anxiety medication for calming patients before surgery, with about 1 in 4 patients experiencing a meaningful benefit. However, almost all of this research has been done in other types of surgery. No study has specifically tested whether letting patients listen to their own preferred music before hip or knee replacement surgery reduces their anxiety. This study will randomly assign 52 patients scheduled for hip or knee replacement surgery to one of two groups: one group will listen to music of their choice through noise-cancelling headphones while waiting for surgery (for at least 20 minutes), and the other group will receive the usual preoperative care without music. Patients will fill out a brief 6-question anxiety survey when they arrive in the preoperative area and again just before being taken to the operating room. The study will also ask patients about their pain, anxiety, and overall experience after surgery, and will review their medical charts to see how much sedation and pain medication was used during the procedure. If music is shown to reduce anxiety in this setting, it could be easily adopted by any hospital at very low cost, offering patients a simple, drug-free way to feel calmer before their surgery.

EMPHASYS Cup Positioning in THA With Non-Invasive Navigation (Velys Hip Navigation (VHN))

The purpose of this research is to gather clinical and radiographic (X-ray) information about EMPHASYS™ acetabular shell (also called a hip 'cup') placement in total hip replacement surgery using a non-invasive surgical navigation system called VELYS™ hip navigation system with CUPTIMIZE™ Advanced Hip-Spine Analysis software. Data collected in this study will be compared with data collected from implantations using different cup positioning instrumentation and techniques to assess performance.

AI-Based Phenome Data Analysis for Predicting the Onset of Major Diseases

This study aims to develop and validate an artificial intelligence (AI)-based predictive model to estimate the risk of incident onset of five major diseases or conditions: cardiovascular disease, type 2 diabetes mellitus, breast cancer, low back pain, and osteoarthritis, in adults aged 30 to 65 years. For each participant, an index date will be defined as the date of a prior health screening or another protocol-defined baseline clinical date. Incident disease status for each target disease or condition will be ascertained by retrospective review of electronic medical records for up to 10 years after the index date. The study integrates retrospective clinical, health screening, laboratory, imaging, and electronic medical record data with prospectively collected biospecimen, proteomic, genomic, questionnaire, lifestyle, and digital health data. Prospective study procedures will be completed over approximately 1 week, with up to 2 additional weeks if needed. By combining multimodal data, this study seeks to improve disease risk prediction and to identify clinical and biological factors associated with disease onset, ultimately supporting personalized risk stratification and preventive healthcare strategies.

Unicompartmental Versus Total Knee Replacement for Medial Compartment Knee Osteoarthritis

For patients with osteoarthritis affecting only the inner part of the knee, surgeons can offer either a partial knee replacement, which resurfaces the worn compartment alone, or a total knee replacement. Both are recommended treatments, but there is no agreement on when to choose one over the other. Partial knee replacement preserves the anterior cruciate ligament and more of the natural knee, and recovery is usually quicker, but it is used in only about one in ten knee replacements in the United Kingdom. Studies comparing the two have mostly relied on patient questionnaires, which may not be sensitive enough to detect differences in how the knee actually functions. Studies that have measured movement directly have concentrated on level walking, which is not demanding enough to separate the two operations. Difficulty with stairs is one of the longest lasting problems patients report after knee replacement. The FLEX-UNI trial will compare the two operations using three-dimensional motion analysis during more demanding everyday activities. Forty patients who are suitable for a partial knee replacement will be randomly allocated to receive either a partial or a total knee replacement. Patients and the researchers measuring their movement will not know which operation was performed. The main measurement is how far the operated knee bends while stepping down from a 20 cm step, measured one year after surgery. Movement during walking, stair climbing, slopes, sitting and standing, and balance will also be measured, along with questionnaires, x-rays, and complications. Results will be compared against measurements from people with healthy knees.

The Effectiveness of Strength Training and Self-management in Reducing Symptoms for Individuals With Knee Osteoarthritis

This study aims to investigate the effectiveness of an intervention combining strength training and self-management education in improving symptoms, sleep quality, emotional well-being, and quality of life in patients with knee osteoarthritis. This study employs a quasi-experimental design. Participants diagnosed with knee osteoarthritis were recruited from the outpatient orthopedics and rehabilitation departments of a public regional teaching hospital in southern Taiwan. They were randomly assigned to either an experimental group (n = 50) or a control group (n = 50). Due to the nature of the intervention, blinding was not feasible, and participants were aware of their group assignment. The experimental group also participated in a home-based strength training program, while the control group received conventional osteoarthritis routine care. Data were collected at baseline, one month, and three months post-intervention during follow-up appointments.
