Bone loss after bariatric surgery is observed mainly in the hip trabecular compartment and after hypoabsorptive techniques.

We evaluated the impact of bariatric surgery on bone mineral density (BMD) and microarchitecture over one year using dual-energy X-ray absorptiometry (DXA), the trabecular bone score (TBS), and 3D-DXA to assess changes after different surgical techniques. This prospective, single-center study of 153 patients with severe obesity contrasts the effects on bone health of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and duodenal switch/single anastomosis duodeno-ileostomy with sleeve gastrectomy (DS/SADIS). To our knowledge, this is the first study to evaluate patients undergoing DS/SADIS and to incorporate 3D-DXA analysis in the assessment of bone loss.

Assessing fatigue in women over 50 years with rheumatoid arthritis: a comprehensive case-control study using the FACIT-F scale.

Introduction: Data on prevalence of fatigue in rheumatoid arthritis (RA) patients in the era of biological treatments remains scarce, with a lack of case-control studies. This study evaluates the prevalence of fatigue in Spanish women over 50 years with RA using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale, explores its association with RA-related variables, and seeks to identify the primary factors influencing fatigue. Ultimately, our objective is to underscore the clinical significance of fatigue as a comorbidity and to advocate for its systematic evaluation in routine clinical practice.

[Cost-effectiveness analysis of fracture liaison services in Catalonia].

Objective: To assess the cost-effectiveness of Fracture Liaison Service (FLS) compared to the standard of care for secondary prevention of fragility fractures form the perspective of the Catalan Health Service.

Methods: Cost-utility assessment through a Markov model that simulated disease progression of a patients' cohort candidates to initiate antiosteoporotic treatment after a fragility fracture. A time horizon of 10 years and a 6-month duration per cycle was established.

High incidence of clinical fragility fractures in postmenopausal women with rheumatoid arthritis. A case-control study.

Objectives: To estimate the incidence of clinical fragility fractures in postmenopausal women with rheumatoid arthritis (RA) and analyze risk factors for fracture.

Methods: Incidence of clinical fragility fractures in 330 postmenopausal women with RA was compared to that of a control population of 660 age-matched postmenopausal Spanish women. Clinical fractures during the previous five years were recorded.
