The clinical significance of BMD discordance has not yet been elucidated. The objective of this study was to evaluate the clinical significance of BMD discordance between the hip and spine for hip fractures. The BMD was measured and related factors were investigated in 109 elderly patients hospitalized for a hip fracture (fracture group) and 109 patients hospitalized without a hip fracture (non-fracture group). BMD discordance of the hip and spine was classified as minor discordance (normal and osteopenia, and osteopenia and osteoporosis) and major discordance (normal and osteoporosis). The risk of hip fracture was calculated according to the type of discordance: no discordance, low hip, and lower spine. There was no significant difference between the general characteristics of the fracture group and the non-fracture group. The rate of BMD discordance and low hip discordance were significantly higher in the fracture group (53.2%, 43.1%) than in the non-fracture group (28.4%, 19.3%). The odds ratio of hip fracture was 2.86 times higher in patients with BMD discordance than in those without discordance and 3.42 times higher in the patients with low hip discordance than in those without no hip discordance. The presence of discordance, particularly when there is low hip discordance, might be related to the hip fractures.

Discordance Between Spine-Hip and Paretic-Nonparetic Hip Bone Mineral Density in Hemiplegic Stroke Patients: A Multicenter Retrospective Study.

Objective: To identify the prevalence and factors associated with T-score discordance between the spine and hip, as well as between the paretic and non-paretic hips in hemiplegic stroke patients, this study investigated bone mineral density (BMD) patterns. Bone loss predominantly affects the paretic hip after a stroke, and typical clinical assessments using dual-energy X-ray absorptiometry (DXA) that scan the lumbar spine (LS) and a single hip may overlook an osteoporosis diagnosis. This oversight could potentially lead to suboptimal treatment for stroke patients.

The commercial use of SiN ceramics in the biomedical field dates back to the early 1980s and, initially, did not show promising results, which is why their biocompatibility was not then investigated further until about 10 years later. Over the years, a change in trend has been observed; more and more studies have shown that this material could possess high biocompatibility and antibacterial properties. However, the relevant literature struggles to find mechanisms that can incontrovertibly explain the reasons behind the biological activity of SiN.

Context: Femoroacetabular impingement syndrome (FAIS) is a movement-related condition associated with pain and impaired function; yet the evidence for level ground walking hip biomechanics is limited and inconsistent. Challenging the hip with inclined walking for individuals with FAIS might be important for elucidating mechanically driven function loss and informing tailored rehabilitation. The purpose of this study was to determine the effects of progressive inclined walking on sagittal hip biomechanics and hip flexor and extensor activity in individuals with FAIS.

Introduction: Osteoarticular infections (OAI) after prosthetic surgery have serious functional and economic consequences. Rapid tests for alpha-defensin (TAD) and leukocyte esterase (TLE) are two intra-articular markers involved in the diagnosis of OAIs. TLE cannot be applied in the presence of blood unless centrifugation is used, but the rate of "non-application" of the test for this reason is unknown in complex microbiological situations (discordant or negative puncture, ongoing antibiotic treatment).

Article Synopsis
- Platypnea orthodeoxia syndrome (POS) is a rare cause of low oxygen levels that requires careful clinical evaluation and collaboration among specialists for diagnosis.
- An 86-year-old male presented to the ER with low oxygen saturation (84%) and did not improve with supplemental oxygen; however, his oxygen levels increased significantly when lying down.
- Diagnosis was confirmed through echocardiography revealing a large patent foramen ovale (PFO) causing a right-to-left shunt; he was treated successfully, improving his oxygen levels and allowing him to go home without supplemental oxygen.*
