Sex and age do not modify the association between glucocorticoids and bone mineral density in patients with rheumatoid arthritis: a cross-sectional study.

BackgroundIt is unclear whether sex or age modify the association of glucocorticoid (GC) use with reduced bone mineral density (BMD) in patients with rheumatoid arthritis (RA).MethodsWe studied cross-sectional data of RA patients with current or previous GC treatment in a single center cohort study (Rh-GIOP cohort). Our primary outcome was the minimum T-score (measured by DXA) of either lumbar spine, total femur, or femoral neck. Current GC dose was the main exposure; cumulative GC dose and cumulative duration of GC use were also assessed. Following a predefined statistical analysis plan, line

Alpha-lipoic acid as a trigger of insulin autoimmune syndrome: Current evidence, a case-based approach, diagnostic pitfalls, and practical management.

Insulin autoimmune syndrome (IAS), also known as Hirata disease, is a rare immune-mediated cause of endogenous hyperinsulinemic hypoglycemia characterized by circulating insulin autoantibodies (IAAs). It typically develops in individuals without prior exposure to exogenous insulin. Although IAS has been associated with viral infections and, less commonly, with autoimmune and hematologic disorders, medications and dietary supplements are considered the most frequent precipitating factors. Sulfhydryl-containing compounds are the most commonly implicated triggers. Methimazole represents the class

Prevalence, Attributes, and Risk Factors of QT-Interval-Prolonging Drugs and Potential Drug-Drug Interactions in Cancer Patients: A Prospective Study in a Tertiary Care Hospital.

Introduction Cancer chemotherapy regimens include multiple classes of adjuvant drugs as supportive therapy. Because of the concurrent intake of other drugs (like antiemetics, antidepressants, analgesics, and antimicrobials), there is a heightened risk for possible QT interval prolongation. There is a dearth of evidence in the literature regarding the usage of QT-prolonging anticancer drugs and associated risk factors that have the propensity to prolong QT interval. The purpose was to explore the extent of the use of QT-interval-prolonging drugs and potential QT-prolonging drug-drug interaction

Recent Advances in Doxorubicin Formulation to Enhance Pharmacokinetics and Tumor Targeting.

Doxorubicin (DOX), a widely used drug in cancer chemotherapy, induces cell death via multiple intracellular interactions, generating reactive oxygen species and DNA-adducted configurations that induce apoptosis, topoisomerase II inhibition, and histone eviction. Despite its wide therapeutic efficacy in solid tumors, DOX often induces drug resistance and cardiotoxicity. It shows limited intestinal absorption because of low paracellular permeability and P-glycoprotein (P-gp)-mediated efflux. We reviewed various parenteral DOX formulations, such as liposomes, polymeric micelles, polymeric nanopar

A Review of Recent Curcumin Analogues and Their Antioxidant, Anti-Inflammatory, and Anticancer Activities.

Curcumin, as the main active component of turmeric (Curcuma longa), has been demonstrated with various bioactivities. However, its potential therapeutic applications are hindered by challenges such as poor solubility and bioavailability, rapid metabolism, and pan-assay interference properties. Recent advancements have aimed to overcome these limitations by developing novel curcumin analogues and modifications. This brief review critically assesses recent studies on synthesising different curcumin analogues, including metal complexes, nano particulates, and other curcumin derivatives, focused o

Urgent considerations on renal immune-related adverse events in oncology practice.

In recent years, immune checkpoint inhibitors (ICIs) have emerged as a critical component of hematological malignancies and solid malignant tumors therapy. However, clinical practice has revealed that these agents may induce immune-related adverse events (irAEs). Notably, renal irAEs stands out as a significant clinical concern, frequently necessitating treatment discontinuation and thereby enabling tumor progression. Renal irAEs constitutes a critical consideration for patients with cancer complicated by chronic kidney disease (CKD). This review systematically examines the immunologic pathoge

The clinical application of angiostatic therapy in combination with radiotherapy: past, present, future.

Although monotherapy with angiostatic drugs is still far from effective, there is abundant evidence that angiostatic therapy can improve the efficacy of conventional treatments like radiotherapy. This has instigated numerous efforts to optimize and clinically implement the combination of angiostatic drugs with radiation treatment. The results from past and present clinical trials that explored this combination therapy indeed show encouraging results. However, current findings also show that the combination has variable efficacy and is associated with increased toxicity. This indicates that com

Tumor microenvironment targeted nano-drug delivery systems for multidrug resistant tumor therapy.

In recent years, nano-drug delivery systems (Nano-DDS) that target the tumor microenvironment (TME) to overcome multidrug resistance (MDR) have become a research hotspot in the field of cancer therapy. By precisely targeting the TME and regulating its unique pathological features, such as hypoxia, weakly acidic pH, and abnormally expressed proteins, etc., these Nano-DDS enable effective delivery of therapeutic agents and reversal of MDR. This scientific research community is increasing its investment in the development of diversified systems and exploring their anti-drug resistance potential.

Loss of EGFR activity in skeletal stem/progenitor cells is associated with impaired fracture healing in aged mice.

The cellular and molecular events responsible for fracture healing becoming delayed with aging remain unclear. Epidermal growth factor receptor (EGFR) signaling has been reported to play a critical role in bone regeneration. However, knowledge of its specific function in skeletal stem cells during aging-induced fracture delayed union remains scant. In the present study, we first demonstrated that EGFR activity in skeletal stem/progenitor cells decreased as mice aged and thus resulted in delayed fracture healing. To further investigate whether the EGFR signaling can be targeted as a potential t

Outcomes of VDPACE with an immunomodulatory agent as a salvage therapy in relapsed/refractory multiple myeloma with extramedullary disease.

Extramedullary disease (EMD) is an aggressive form of multiple myeloma (MM). Confirming the presence of plasma cells outside the bone marrow makes the diagnosis of EMD. There is no clear consensus on the management of EMD in MM, and this entity continues to remain an unmet need. Rapidly controlling EMD to prevent end-organ damage is a priority. Retrospectively, we reviewed our database for patients with EMD that received treatment with bortezomib, dexamethasone, cisplatin, doxorubicin, cyclophosphamide, etoposide (VDPACE) plus an immune modulator (IMiD) regimen. We identified 21 patients with

Transforming tumor microenvironments: nanotechnology and gene therapy in cellular signaling and epigenetic insight into chemo-resistance.

Chemoresistance remains the primary cause of cancer treatment failure, yet current understanding remains fragmented across isolated mechanistic studies. This review provides a unified framework linking tumor microenvironment (TME) signaling, epigenetic reprogramming, and nanotherapeutic intervention as an integrated axis driving and potentially reversing chemoresistance. We systematically examine how TME components: hypoxia (HIF-1α pathway), acidosis, cancer-associated fibroblasts (TGF-β/PDGF signaling), and immune cells (NF-κB-mediated immunosuppression) activate signaling cascades that direc
