Objective: Osteoporosis is a systemic bone disease that seriously threatens the health and quality of life in middle-aged and older adults. In this review, we describe the relationship between bone marrow adipose tissue and aging osteoporosis and mainly focus on bone marrow mesenchymal stem cell osteogenic-adipose differentiation fate with aging along with the relevant mechanisms responsible for these changes.
Methods: We summarized recent advances in regulating the bone marrow mesenchymal stem cell differentiation due to aging in this review.
Results: Aging-related bone mass loss is accompanied by expanding bone marrow adipose because of an imbalance of bone marrow mesenchymal stem cell differentiation, resulting in adipogenesis. Ectopic adipocytes in the bone marrow increase with age and are a key factor responsible for the aging-related bone mass decrease. Transcription factors and classical regulating pathways are involved in this process during aging.
Conclusion: As the global aging population increases, not only older women but also older men face a great fracture risk. Therefore, finding molecular mechanisms controlling the stimulating adipogenesis in BMSC during aging is important for providing the new cue for prevention and therapeutics for aging-related bone loss. Furthermore, upon physical examination of older people, except for the bone mineral density and bone turnover biochemical marker, the bone marrow adipose measurement should be taken into account when assessing the fracture risk and treatment plan that will be beneficial in clinical practice.

Background: Bone marrow (BM) lesion differentiation remains challenging, and quantitative magnetic resonance imaging (MRI) may enhance accuracy over conventional methods. We evaluated the diagnostic value and inter-reader reliability of Dixon-based signal drop (%drop) and fat fraction percentage (%fat) as adjuncts to existing protocols.
Materials And Methods: In this prospective two-center study, 172 patients with BM signal abnormalities underwent standardized 1.

Osteoporotic fractures are notoriously difficult to heal due to an imbalance between osteoblasts and osteoclasts. Current treatments often have limited efficacy or adverse side effects, necessitating safer and more effective solutions. Here, we developed an injectable plant-derived phosphate coordination compound-based adhesive hydrogel (MgPA-Gel) to restore bone homeostasis by integrating magnesium ions (Mg)-phytic acid (PA) nanoparticles with aminated gelatin (Gel-NH) and aldehydated starch (AS).

Background: Critically ill pediatric patients admitted to the PICU are highly vulnerable to infections, including invasive fungal diseases and antifungal agents are frequently prescribed. Little is known about antifungal usage in PICUs across Europe.
Methods: A multinational 3-month weekly point-prevalence study for measuring antifungal drug use was organized.

Unlabelled: B-cell lymphomas are highly aggressive forms of lymphoma that commonly present with lymphadenopathy, systemic "B" symptoms, or organ involvement making them easy to recognize; however, a small percentage of B-cell lymphomas can present without any typical symptoms or evidence of lymphadenopathy, resulting in delayed recognition and management. Isolated thrombocytopenia without anaemia or leukopenia is an unusual presentation of B cell lymphomas and may be misdiagnosed as immune thrombocytopenia (ITP). Given the rarity of this presentation, we wish to report a case of a 76-year-old female who presented with palpitations, shortness of breath, and recurrent chest infections.

Background: Blinatumomab and inotuzumab ozogamicin (InO) are B-cell targeted agents used in the frontline and relapsed/refractory treatment of B-cell acute lymphoblastic leukaemia (B-ALL). Blinatumomab, a bispecific T-cell engager that targets CD19 and CD3, and InO, an antibody-drug conjugate targeting CD22, have both shown efficacy. However, recent reports have noted lineage conversion as a complication when these agents are used individually or sequentially.
