Long-term evaluation of rheumatoid arthritis activity with erythrocyte methotrexate-polyglutamate 3.

Background: Methotrexate (MTX) is the first-line treatment for Rheumatoid Arthritis (RA), yet 30%-50% of RA patients develop resistance to MTX, which can manifest several years after treatment initiation.

Objective: This study investigates the relationship between erythrocyte methotrexate polyglutamates (MTX-PGs) subtype concentrations and clinical disease activity in RA patients undergoing long-term MTX treatment.

Methods: In this cross-sectional study, patients on a stable dose of subcutaneous MTX for several years were included.

Proteomics analyses of human plasma reveal triosephosphate isomerase as a potential blood marker of methotrexate resistance in rheumatoid arthritis.

Objective: The objective of this study was to assess differentially expressed blood proteins between patients with active RA and patients in remission after MTX treatment, with the aim of identifying a biomarker of MTX resistance (MTXR).

Methods: Two populations of RA patients treated with a stable dose of s.c.

The effects of combined amplitude and high-frequency vibration on physically inactive osteopenic postmenopausal women.

To evaluate whole-body vibration (WBV) osteogenic potential in physically inactive postmenopausal women using high-frequency and combined amplitude stimuli. Two-hundred fifty-five physically inactive postmenopausal women (55-75 years) with 10-year major osteoporotic fracture risk (3%-35%) participated in this 18-month study. For the first 12 months, the vibration group experienced progressive 20-min WBV sessions (up to 3 sessions/week) with rest periods (30-60 s) between exercises.

Costs of patient management over 18 months following a hip, clinical vertebral, distal forearm, or proximal humerus fragility fracture in France-results from the ICUROS study.

Unlabelled: This observational study prospectively assessed direct and indirect costs related to patient management over 18 months following hip, clinical vertebral, humeral, or distal forearm fracture events in France. It appears that their levels were much higher than the previous estimates, raising the burden of osteoporosis-related fractures on public health expenditures.

Introduction: This prospective observational study assessed the costs related to patient management over the 18-month period following the event of a hip, clinical vertebral, humeral, or distal forearm fracture in France.

Reference microarchitectural values measured by HR-pQCT in a Franco-Swiss cohort of young adult women.

Unlabelled: Bone microarchitecture assessed by high-resolution peripheral quantitative computed tomography varies across populations of different origin. The study presents a reference dataset of microarchitectural parameters in a homogeneous group of participants aged within 22-27 range determined by a discriminant analysis of a larger cross-sectional cohort of 339 women.

Introduction: High-resolution peripheral quantitative computed tomography (HR-pQCT) non-invasively measures three-dimensional bone microarchitectural parameters and volumetric bone mineral density.

Remaining local subclinical joint inflammation is associated with deteriorated metacarpeal head bone microarchitecture in rheumatoid arthritis patients low disease activity.

Objectives: Bone alterations at the subchondral level during rheumatoid arthritis (RA) remain under investigation. It remains unknown whether subchondral bone damage might still occur in RA patients in clinical remission, which could then infer suggesting that even minor subclinical inflammatory changes in the joint can induce local bone loss.

Methods: Thirty-two RA patients treated with biological disease-modifying anti-rheumatic drugs (bDMARDs) with low disease activity since at least 6 months and having erosion on the second or third metacarpeal head were enrolled in this pilot cross-sectional study.

Cortical and Trabecular Bone Microstructure Did Not Recover at Weight-Bearing Skeletal Sites and Progressively Deteriorated at Non-Weight-Bearing Sites During the Year Following International Space Station Missions.

Risk for premature osteoporosis is a major health concern in astronauts and cosmonauts; the reversibility of the bone lost at the weight-bearing bone sites is not established, although it is suspected to take longer than the mission length. The bone three-dimensional structure and strength that could be uniquely affected by weightlessness is currently unknown. Our objective is to evaluate bone mass, microarchitecture, and strength of weight-bearing and non-weight-bearing bone in 13 cosmonauts before and for 12 months after a 4-month to 6-month sojourn in the International Space Station (ISS).
