Atypical femur fractures (AFFs) have been reported with long term use of anti-resorptive drugs. Early identification is crucial because it allows early intervention to stop the progression to complete fracture, thus potentially reducing the ensuing burden. It has been shown that extending the scan image to take a full-length image of the femur (FFI) using single energy (SE) X-rays at the time of a dual-energy X-ray absorptiometry (DXA) scan can detect findings in the spectrum of AFF.

Article Synopsis
  • Fibrodysplasia ossificans progressiva (FOP) is a rare disorder causing painful flare-ups and abnormal bone growth, known as heterotopic ossification (HO).
  • In a clinical trial, patients receiving the anti-activin A antibody garetosmab experienced fewer severe and lengthy flare-ups compared to those given a placebo, leading to a notable difference in quality of life.
  • The study found that 71% of placebo patients had flare-ups linked to new HO lesions, while garetosmab reduced the severity, duration, and frequency of these flare-ups throughout the trial.

Article Synopsis
  • The primary goal of osteoporosis management is to prevent fractures through individualized, goal-directed treatment plans.
  • Effective treatment requires assessing a patient's fracture history, bone mineral density (BMD), and other major risk factors to determine the best course of action.
  • Initial treatment should prioritize rapid fracture risk reduction for high-risk patients and take into account the likelihood of meeting BMD targets with either osteoanabolic or antiresorptive therapies.

Pentosidine (PEN) is an Advanced Glycation End-product (AGE) that is known to accumulate in bone collagen with aging and contribute to fracture risk. The PEN content in bone is correlated with serum PEN, making it an attractive, potential osteoporosis biomarker. We sought to develop a method for quantifying PEN in stored serum.

Article Synopsis
  • Osteoporosis is diagnosed using bone mineral density (BMD) measured by DXA, but other skeletal factors also impact bone strength and fracture risk.
  • Lumbar spine texture analysis (TBS) enhances fracture prediction beyond BMD and can be used to refine fracture risk assessments, particularly for patients aged 40 and older who are nearing treatment thresholds.
  • Recommendations include using TBS from L1-L4 vertebrae for adjusted FRAX calculations and noting that TBS changes may not be useful with current methods, although future updates to the algorithm may improve its effectiveness.

Background: While scientific knowledge of post-COVID-19 condition (PCC) is growing, there remains significant uncertainty in the definition of the disease, its expected clinical course, and its impact on daily functioning. Social media platforms can generate valuable insights into patient-reported health outcomes as the content is produced at high resolution by patients and caregivers, representing experiences that may be unavailable to most clinicians.

Objective: In this study, we aimed to determine the validity and effectiveness of advanced natural language processing approaches built to derive insight into PCC-related patient-reported health outcomes from social media platforms Twitter and Reddit.

Objective: The purpose of this trial is to evaluate the effect of twice-weekly, moderate-to-high intensity progressive resistance training (PRT) for 1 year on lumbar spine bone mineral density (BMD) in individuals with low BMD, compared to attention control. Secondary analyses will examine if resistance training improves other health outcomes; if high intensity is more effective than moderate intensity resistance training for all outcomes; the cost of intervention versus benefit; the willingness to pay; and harms.

Methods: For this study, 324 men or postmenopausal women aged ≥50 years with a femoral neck, total hip, or lumbar spine BMD T-score of ≤-1, or a Fracture Risk Assessment Tool probability of ≥20% for major osteoporotic fracture or ≥ 3% for hip fracture are being recruited to participate in a randomized controlled trial with 1:1:1 randomization.
