Экстраклектные везикли для клинической диагностики: от массовых измерений до одновидового анализа.

Экстраклектные везикулы (ЭМ) играют ключевую роль в межклеточном общении, сигнальных путях и патогенезе заболеваний, перевозя биомолекулы, такие, как ДНК, РНК, белки и липиды, полученные из клеток их происхождения, и они продемонстрировали значительный потенциал в области клинического применения. Их клиническое значение подчеркивает необходимость применения чувствительных методов для полной реализации их диагностического потенциала. В рамках этого всеобъемлющего обзора мы изучаем гетерогенность ЭМ, связанную с биогенезом, структурой, содержанием, происхождением, типом выборки и функциональными

Recent Advances in the Treatment of Patients with Multiple Myeloma.

In the past 20 years, few diseases have seen as great progress in their treatment as multiple myeloma. With the approval of many new drugs and the limited availability of clinical trials comparing head-to-head the different possible combinations, the choice of the best treatments at each stage of the disease becomes complex as well as crucial since multiple myeloma remains incurable. This article presents a general description of the novelties of the whole treatment of multiple myeloma, from induction in the newly diagnosed patient through the role of hematopoietic stem cell transplantation an

Imaging for Plasma Cell Dyscrasias: What, When, and How?

Imaging plays a vital role in the diagnosis, response assessment, and follow-up of patients with plasma cell bone disease. The radiologic diagnostic paradigm has thus far evolved with developing technology and availability of better imaging platforms; however, the skewed availability of these imaging modalities in developed vis-à-vis the developing countries along with the lack of uniformity in reporting has led to a consensus on the imaging criteria for diagnosing and response assessment in plasma cell dyscrasia. Therefore, it is imperative for not only the radiologists but also the treating

Парадигм Смена в Моноклональном Обнаружении Протеина: От электрофореза до Массовых Спектрометрических методов.

Моноклональный белок (M-протеин) является важнейшим биомаркером для диагностики и мониторинга моноклональных гаммопатий, включая множественную миелому (ММ). Традиционно для обнаружения M-протеинов широко использовались такие основанные на электрофорезе (ЭП) методы, как белковый EP и иммунофиксационный EP. Однако эти методы могут свидетельствовать о низкой чувствительности и недостаточной количественной оценке небольших количеств М-протеина. Для преодоления этих проблем методы, основанные на ЭП, часто сочетаются с количественной оценкой свободных световых цепочек в автоматизированных иммуномасс

The objective of this study was to determine whether these ethical principles relate to over-/undertreatment for older adults, and how tensions among the principles may contribute.MethodsWe conducted a modified Delphi study with 13 experts in biomedical ethics for iterative rounds of data collection. In the first round, we presented via electronic questionnaire our previously published definitions of

Extracellular Vesicles in Diffuse Large B Cell Lymphoma: Characterization and Diagnostic Potential.

Diffuse large B cell lymphoma (DLBCL) is an aggressive B cell lymphoma characterized by a heterogeneous behavior and in need of more accurate biological characterization monitoring and prognostic tools. Extracellular vesicles are secreted by all cell types and are currently established to some extent as representatives of the cell of origin. The present study characterized and evaluated the diagnostic and prognostic potential of plasma extracellular vesicles (EVs) proteome in DLBCL by using state-of-the-art mass spectrometry. The EV proteome is strongly affected by DLBCL status, with multiple

Stereotactic Body radiotherapy and pedicLE screw fixatioN During one hospital visit for patients with symptomatic unstable spinal metastases: a randomized trial (BLEND RCT) using the Trials within Cohorts (TwiCs) design.

BackgroundSpinal metastases can lead to unremitting pain and neurological deficits, which substantially impair daily functioning and quality of life. Patients with unstable spinal metastases receive surgical stabilization followed by palliative radiotherapy as soon as wound healing allows. The time between surgery and radiotherapy delays improvement of mobility, radiotherapy-induced pain relief, local tumor control, and restart of systemic oncological therapy. Stereotactic body radiotherapy (SBRT) enables delivery of preoperative high-dose radiotherapy while dose-sparing the surgical field, al

From Molecular Precision to Clinical Practice: A Comprehensive Review of Bispecific and Trispecific Antibodies in Hematologic Malignancies.

Multispecific antibodies have redefined the immunotherapeutic landscape in hematologic malignancies. Bispecific antibodies (BsAbs), which redirect cytotoxic T cells toward malignant targets via dual antigen engagement, are now established components of treatment for diseases such as acute lymphoblastic leukemia (ALL), diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), and multiple myeloma (MM). Clinical trials of agents like blinatumomab, glofitamab, mosunetuzumab, and teclistamab have demonstrated deep and durable responses in heavily pretreated populations. Trispecific antibodi

Comparison of efficacy, safety, patients' quality of life, and doctors' occupational stress between lenalidomide-based and bortezomib-based induction in patients with newly diagnosed multiple myeloma.

BACKGROUND: In the new therapeutic era, comparisons between regimens containing lenalidomide and bortezomib are needed. METHODS: In this single-center, prospective study, patients received four to six cycles of lenalidomide+liposomal doxorubicin+dexamethasone (RAD) or bortezomib+liposomal doxorubicin+dexamethasone (PAD) every 4 weeks, with subsequent autologous stem cell transplantation (ASCT) and maintenance therapy. We compared the efficacy, safety, patients' quality of life, and doctors' occupational stress between RAD and PAD induction in newly diagnosed MM patients. RESULTS: The complet

Patient-reported outcomes following autologous stem cell transplant for patients with multiple myeloma.

We evaluated changes in patient-reported outcomes and cognitive function from pre- to 3-6 months post-treatment among 42 newly diagnosed patients with multiple myeloma undergoing transplant with complete data using PROMIS-29. There were statistically significant improvements in physical (p < .001) and mental health (p < .001) but not cognition from pre-treatment to 3-6 month follow-up. Similar results were seen within age or comorbidity strata. Patients with myeloma undergoing transplant experienced generally improved short-term health outcomes with no significant declines in cognition.

A novel targeted lung denervation multi-polar radiofrequency ablation system for moderate to severe COPD patients: a translational study.

BACKGROUND: Disruption of parasympathetic pulmonary nerves, which release acetylcholine and trigger airway smooth muscle constriction, has been shown to improve lung function and alleviate symptoms in patients with chronic obstructive pulmonary disease (COPD). However, the current targeted lung denervation (TLD) mono-polar radiofrequency (RF) ablation system has the potential for structural improvement to enhance the generalizability and safety of the TLD procedure. OBJECTIVE: To develop a novel TLD multi-polar RF ablation for COPD treatment and evaluate its feasibility, safety, and efficacy.

Guided immunotherapy for residual solid tumor: integrating platelets and CAR T cells to reduce post-surgical recurrence.

Postoperative recurrence remains a major obstacle to durable remission in patients with solid tumors, even after complete macroscopic resection. Growing evidence suggests that surgery creates a transient yet highly permissive biological window characterized by inflammatory signaling, coagulation activation, endothelial disruption, and systemic immune suppression. Together, these processes foster a protective niche that enables microscopic residual disease to evade immune surveillance and initiate metastatic outgrowth. Although modern adjuvant therapies have improved outcomes, their effectivene

Recent advances and clinical pharmacology aspects of Chimeric Antigen Receptor (CAR) T-cellular therapy development.

Advances in immuno-oncology have provided a variety of novel therapeutics that harness the innate immune system to identify and destroy neoplastic cells. It is noteworthy that acceptable safety profiles accompany the development of these targeted therapies, which result in efficacious cancer treatment with higher survival rates and lower toxicities. Adoptive cellular therapy (ACT) has shown promising results in inducing sustainable remissions in patients suffering from refractory diseases. Two main types of ACT include engineered Chimeric Antigen Receptor (CAR) T cells and T cell receptor (TCR

A new era in myeloma: the advent of chimeric antigen receptor-T (CAR-T) cells and bispecific antibodies.

T-cell re-directional therapies, including chimeric antigen receptor (CAR)-T cell and bispecific antibodies (BsA), have transformed the treatment landscape to benefit patients with multiple myeloma. A number of these novel therapies has been approved internationally, with CAR-T therapy recently approved in Australia. In this clinical perspective, we describe the development of CAR-T and BsA therapies, highlighting the clinical benefits and risks, together with the significant costs and infrastructure support required for the provision of these therapies to myeloma patients.
