Identification of potential biomarkers and therapeutic targets for osteoarthritis associated with arginine and proline metabolism based on transcriptome sequencing and bioinformatics.

Background and objectivesOsteoarthritis (OA) is a chronic degenerative joint disease. Approximately 300 million people worldwide suffer from OA, which shows a high incidence in middle-aged and elderly populations, with a prevalence of 50% among individuals aged over 60 years. Its core clinical symptoms consist of joint pain, swelling, and dysfunction. Studies have shown that arginine and proline metabolism play an important role in the pathogenesis and progression of OA, but the specific mechanism is still unclear. This study aimed to identify biomarkers and drug therapeutic targets for OA ass

Mathematical modeling in cancer nanomedicine: a review.

Cancer continues to be among the leading healthcare problems worldwide, and efforts continue not just to find better drugs, but also better drug delivery methods. The need for delivering cytotoxic agents selectively to cancerous cells, for improved safety and efficacy, has triggered the application of nanotechnology in medicine. This effort has provided drug delivery systems that can potentially revolutionize cancer treatment. Nanocarriers, due to their capacity for targeted drug delivery, can shift the balance of cytotoxicity from healthy to cancerous cells. The field of cancer nanomedicine h

A single-center 7-year experience with end-stage renal disease care in Nigeria-a surrogate for the poor state of ESRD care in Nigeria and other sub-saharan african countries: advocacy for a global fund for ESRD care program in sub-saharan african countries.

Background. A single-center ESRD care experience in a Nigerian teaching hospital is presented as a surrogate case to demonstrate the prevailing ESRD care situation in Nigeria and most SSA countries. Methods. The data of 320 consecutive ESRD patients undergoing maintenance haemodialysis treatment during a seven-year period were retrospectively analyzed. Results. Over 80% of the subjects funded dialysis treatments from direct out of pocket payment. The mean duration on dialysis before dropout was 5.2 ± 7.6 weeks, with majority 314 (98.1%) of the patients unable to sustain dialysis above 12 weeks

Lenalidomide plus Dexamethasone Combination as First-Line Oral Therapy of Multiple Myeloma Patients: A Unicentric Real-Life Study.

Based on the results obtained in clinical trials, the use of the combination of lenalidomide and dexamethasone (Len/Dex) has become a potential therapeutic choice for newly diagnosed multiple myeloma (NDMM) ineligible for autologous stem cell transplantation. This study evaluated 89 frail NDMM patients treated with first-line oral association. At the last follow-up, 34 out of 89 patients (38.2%) were alive, and 22 were still in treatment with Len/Dex. Among 73 evaluable patients who received at least two cycles, the overall response rate was 71% (N = 52). The disease control rate, defined as a

Elevated D-dimer levels in high-risk multiple myeloma patients: a systematic review and meta-analysis.

BACKGROUND: Patients with multiple myeloma (MM) exhibit elevated thrombotic risk and variable disease outcomes. D-dimer, a fibrin degradation product, may serve as a biomarker reflecting both hypercoagulability and disease severity. This systematic review and meta-analysis compared D-dimer levels between MM patient subgroups defined by either poor prognostic features (e.g., advanced ISS stage) or thrombotic events and reference groups, with detailed discussion of how D-dimer integration reshapes routine thromboprophylaxis strategies and upgrades classic prognostic staging tools (ISS, R-ISS, IM

Inflammatory Signaling Pathways in Preleukemic and Leukemic Stem Cells.

Hematopoietic stem cells (HSCs) are a rare subset of bone marrow cells that usually exist in a quiescent state, only entering the cell cycle to replenish the blood compartment, thereby limiting the potential for errors in replication. Inflammatory signals that are released in response to environmental stressors, such as infection, trigger active cycling of HSCs. These inflammatory signals can also directly induce HSCs to release cytokines into the bone marrow environment, promoting myeloid differentiation. After stress myelopoiesis is triggered, HSCs require intracellular signaling programs to

Molecularly targeted therapy and immunotherapy in leukemias.

The advent of next-generation high-throughput sequencing and precision medicine has allowed the identification of recurrent genetic events of vital interest for leukemic cells and for the management of patients with leukemia, since it has a direct impact on prognosis and therapeutic stratification. The precise cytogenetic characterization of these diseases has rapidly enabled the development of innovative therapeutic strategies to improve outcomes and limit toxicities. New targeted therapies, including small molecule inhibitors, monoclonal antibodies, bispecific T cell engagers, antibody-drug

Cancer-related cognitive impairment in patients with hematologic malignancies after CAR T cell therapy: a systematic review and meta-analysis of prevalence.

PURPOSE: Cancer-related cognitive impairment is one of the symptoms of neurotoxicity among patients receiving chimeric antigen receptor (CAR) T cell therapy. Evidence of the overall estimated prevalence of cancer-related cognitive impairment following CAR T-cell therapy among patients with hematologic malignancies at short-term and long-term follow-ups is lacking. This review aimed to summarize the cognitive functioning status and estimate the prevalence of cancer-related cognitive impairment at follow-up within 1 month, 1 to 12 months, and > 12 months after CAR T cell therapy.

Relapsed/Refractory Multiple Myeloma: A Review of Available Therapies and Clinical Scenarios Encountered in Myeloma Relapse.

Multiple myeloma remains an incurable disease with the usual disease course requiring induction therapy, autologous stem cell transplantation for eligible patients, and long-term maintenance. Risk stratification tools and cytogenetic alterations help inform individualized therapeutic choices for patients in hopes of achieving long-term remissions with preserved quality of life. Unfortunately, relapses occur at different stages of the course of the disease owing to the biological heterogeneity of the disease. Addressing relapse can be complex and challenging as there are both therapy- and patie

Multidisciplinary treatment system for bone metastases for early diagnosis, treatment and prevention of malignant spinal cord compression.

Malignant spinal cord compression (MSCC) is a serious complication of cancers. The present study aimed to establish a multidisciplinary treatment system for urgent magnetic resonance imaging (MRI) and referral to orthopedists in order to prevent neurological deficits caused by MSCC. In the present study, the extent to which this system achieved early diagnosis and treatment and prevented MSCC-caused neurological deficits was examined. The records from patients with neurological deficits caused by MSCC before (between April 2007 and March 2012; group A) and after (between April 2012 and March 2

Clinical uses of GM-CSF, a critical appraisal and update.

The role of granulocyte-macrophage-colony-stimulating factor (GM-CSF) in the supportive care of cancer patients has been evaluated with promising results. More recently, GM-CSF has been added to regimens for the mobilization of hematopoietic progenitor cells. An expanding role for GM-CSF in regulating immune responses has been recognized based upon its activity on the development and maturation of antigen presenting cells and its capability for skewing the immune system toward Th1-type responses. GM-CSF has been shown to preferentially enhance both the numbers and activity of type 1 dendritic

Расширение пространственной стеноскопии для крупных тканей: обнаружение архитектуры тканей клеточного уровня за пределами обычных платформ с iSCALE.

Последние достижения в технологии пространственной транскриптомики (ST) изменили нашу способность профилировать выражение генов при сохранении критического пространственного контекста в тканях. Однако существующие платформы ST сопряжены с высокими затратами, длительными сроками перехода, низкой разрешающей способностью, ограниченным генным охватом и небольшими зонами захвата тканей, что препятствует их широкому применению. Здесь мы представляем iSCALE, метод, который предсказывает выражение гена супер разрешения и автоматически аннотирует архитектуру ткани клеточного уровня для крупных тканей,

Anaplastic thyroid cancer cells reduce CD71 levels to increase iron overload tolerance.

BackgroundFollicular thyroid cancer (FTC) is a prevalent form of differentiated thyroid cancer, whereas anaplastic thyroid cancer (ATC) represents a rare, fast-growing, undifferentiated, and highly aggressive tumor, posing significant challenges for eradication. Ferroptosis, an iron-dependent cell death mechanism driven by the excessive production of reactive oxygen species and subsequent lipid peroxidation, emerges as a promising therapeutic strategy for cancer. It has been observed that many cancer cells exhibit sensitivity to ferroptosis, while some other histotypes appear to be resistant,
