Drug resistance and tumor immune microenvironment: An overview of current understandings (Review).

The use of antitumor drugs represents a reliable strategy for cancer therapy. Unfortunately, drug resistance has become increasingly common and contributes to tumor metastasis and local recurrence. The tumor immune microenvironment (TME) consists of immune cells, cytokines and immunomodulators, and collectively they influence the response to treatment. Epigenetic changes including DNA methylation and histone modification, as well as increased drug exportation have been reported to contribute to the development of drug resistance in cancers. In the past few years, the majority of studies on tum

Их основной ранней токсичностью является синдром выброса цитокина (CRS), который обычно носит переходный характер и ограничивается начальными циклами. Мы сообщаем five - пациенты с рецидивной или рефрактной множественной миэломой, получившие биконкретные антитела (n = 1 teclistamab; n = 4 Talquetamab), который разработал модель повторя

Oral manifestations and dental management in patients undergoing CAR-T cell therapy: a retrospective observational study.

Chimeric antigen receptor T-cell (CAR-T) therapy has emerged as a highly effective treatment for refractory and relapsed hematologic malignancies. Despite its clinical benefits, CAR-T therapy is associated with a unique toxicity profile, including cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), and prolonged immunosuppression. Oral complications in this population remain underreported. This retrospective case series was aimed at describing oral manifestations and dental management in patients undergoing CAR-T therapy at a tertiary referral cente

Multical Sclerosis Severity Alle res10191329A и Когнитивная функция: UK Biobank Study.

В рамках исследования, проведенного в рамках всей ассоциации генома по вопросу о жесткости множественных склерозов, генетический вариант rs10191329A увязывался с долгосрочной инвалидностью и в качестве одного из определяющих факторов исхода учитывала устойчивость мозга. Мы гипотезали, что rs10191329A может повлиять на когницию других неврологических заболеваний и здоровый контроль. Мы изучили связь между rs10191329A и когницией с использованием времени реакции, жидкого интеллекта и возможных тестов памяти в Биобанке Великобритании. Мы наблюдали слабые, но последовательные связи между rs1019132

Двойная автономность: синдром Эванса и множественный склероз.

Синдром Эванса (ES) — редкое аутоиммунное расстройство, связанное с аутоиммунной гемолитической анемией и иммунной тромбоцитопенией (ИТП). Пациенты, как правило, страдают от петехии, пурпуры, паллора и усталости. Диагностические критерии включают в себя положительное прямое антиглобулиновое испытание, ретикулокитоз, снижение уровня гаптоглобина, а также повышенный косвенный уровень билюродина и лактата дегидрогеназы. ЭУ может быть связано с другими аутоиммунными заболеваниями, включая системный волчанки эритематос, ревматоидный артрит и аутоиммунный гепатит. Вместе с тем в научной литературе в

Sequential Development of Waldenström's Macroglobulinemia After High-Grade Lymphomatoid Granulomatosis.

Lymphomatoid granulomatosis (LYG) is a rare Epstein-Barr virus-driven B-cell lymphoproliferative disease that often progresses to high-grade lymphoma. We describe a case of high-grade LYG causing Pancoast syndrome, diagnosed via transbronchial biopsy after a failed incisional biopsy. Complete remission was achieved with R-CHOP (rituximab, doxorubicin, cyclophosphamide, vincristine, and prednisolone), but 2.5 years later, the patient developed lymphoplasmacytic lymphoma/Waldenström's macroglobulinemia (LPL/WM). Despite bendamustine-rituximab improving LPL/WM, LYG recurred, underscoring its trea

Outcomes of Patients with Hematological Malignancies Admitted to the Intensive Care Unit at a Tertiary Care Center in Saudi Arabia.

BackgroundPatients with hematological malignancies (HM) are at risk for complications, including neutropenia and admission to the intensive care unit (ICU). Granulocyte colony-stimulating factors (GCSF) can accelerate progenitor cells' proliferation and differentiation, and thus compensate for neutropenia. In patients with HM admitted to ICUs in Saudi Arabia, the outcome and impact of GCSF use on neutropenia duration and severity is understudied.ObjectiveTo evaluate the outcome and impact of GCSF on neutropenia in patients with HM admitted to the ICU of a tertiary care center in Saudi Arabia.M

Fatigue as main symptom in an elderly multiple myeloma patient: a Case Report.

INTRODUCTION: The high prevalence of fatigue as an atypical clinical manifestation in general practice creates notable diagnostic challenges, particularly in geriatric patients. METHODS: We describe a case of an 80-year-old female presenting with fatigue, initially attributed to poorly controlled diabetes mellitus or upper respiratory infection, who was ultimately diagnosed with multiple myeloma after admitted to the Department of General Medicine at a general hospital. Initial diagnostic workup including physical examination revealed the presence of anterior thoracic mass with undetermined e

Мы сообщаем о сложном случае с 32-летней ранее здоровой беременной женщиной при 17+2-недельной беременности с новым диагнозом исключительно высокоактивного релапсирующего множественного склероза (RRMS), спровоцированного интенсивным острым респираторным синдромом коронавируса 2 (SARS-COV-2). Замечательными клиническими характеристиками были быстрое ухудшение клинического состояния, серьезность и характер симптомов, включая спастическую тетраплегию, диспнею, дисфагию, анартхрию и синдром сильной боли, что привело к необходимости интенсивной терапии и механической вентиляции в течение 24 часов.

Paradoxical Left Ventricular Hypertrophy by Echocardiogram and Low Voltage ECG: A Key Clue in the Diagnostic Workup of Two Distinct Presentations of Cardiac AL Amyloidosis.

Cardiac amyloidosis remains a rare disease caused by the extracellular deposition of abnormal proteins-amyloids in the myocardium. These protein structures in the myocardium are associated with high morbidity and mortality, with prognosis hinging on early detection and treatment. Three main types of cardiac amyloidosis have been identified: light chain (AL), familial or senile (ATTR), and secondary amyloidosis which is associated with chronic inflammation. Cardiac amyloidosis classically presents as diastolic heart failure with symptoms of volume overload low voltage on electrocardiogram (ECG)

Case report: Relapsed/refractory extranodal natural killer/T-cell lymphoma nasal type with extensive central nervous system involvement.

Background: Extranodal natural killer/T-cell lymphoma (ENKL) is a rare subtype of mature T and natural killer cell lymphomas associated with Epstein-Barr virus. Case: A 20-year-old presented with severe neurological symptoms and was diagnosed with stage IV ENKL, nasal type, with CNS involvement. Overall, the patient received nine treatment lines, including chemotherapy, craniospinal irradiation, allogeneic stem cell transplant (alloSCT), donor lymphocyte infusions, and novel agents (Nivolumab, Daratumumab, Thalidomide, Lenalidomide, virus-specific T cells) combined with intrathecal chemotherap

Hypercalcemia-Leukocytosis syndrome and adenosquamous lung carcinoma: An overlooked conjugation.

Hypercalcaemia and leukocytosis are two paraneoplastic conditions associated with poor prognosis. Adenosquamous carcinoma is a rare and aggressive histological subtype of lung cancer consisting of adenocarcinoma and squamous cell components. We report the case of a 57-year-old male smoker who was admitted to the Emergency Room with skull and neck tumefactions, confusion and deteriorated general condition. The complementary study in the ER revealed severe hypercalcaemia (19.8 mg/dL), leukocytosis (18.7 × 109/L) and extensive osteolytic lesions of the skull on cranioencephalic computer tomograph

Subspecialty Second-Opinion in Multiple Myeloma CT: Emphasis on Clinically Significant Lytic Lesions.

Background and objectives: In order to increase the accuracy of lytic lesion detection in multiple myeloma, a dedicated second-opinion interpretation of medical images performed by subspecialty musculoskeletal radiologists could increase accuracy. Therefore, the purpose of this study is to evaluate the added value (increased accuracy) of subspecialty second-opinion (SSO) consultations for Computed Tomography (CT) examinations in Multiple Myeloma (MM) patients undergoing stem cell transplantation on standard computed tomography with a focus on focal lesion detection. Materials and Methods: Appr

Dynamic thiol and disulphide homoeostasis in fibromyalgia.

BACKGROUND AND PURPOSE: Contrast therapy consists of alternating thermotherapy and cryotherapy repeatedly to assist in the management of acute, subacute, and chronic musculoskeletal conditions. This has been utilized for several decades with good to excellent subjective and objective results reported for patients with swelling (acute to chronic), pain, and loss of motion. Typically, the intervention is performed by either the use of a hot and cold whirlpool or by applying hot and cold packs which can be very time consuming and labor intensive. The purpose of this study was to determine the eff

Paradoxical Stress Fracture in a Patient With Multiple Myeloma and Bisphosphonate Use.

Multiple myeloma (MM) is a plasma cell disorder with related organ dysfunction, including hypercalcemia, renal insufficiency, anemia, and bone disease. Osteolytic bone lesions that result in pain and pathologic fractures are a major source of morbidity and the use of bisphosphonates is generally safe and effective treatment in reducing myeloma-related skeletal fractures and associated morbidity. We present a 73-year-old African American woman with MM in remission and on intravenous (IV) bisphosphonate therapy in the past five years who reported gradually worsening bilateral thigh pain of six m

On 21 November 2016, the European Commission issued a marketing authorisation valid throughout the European Union for ixazomib in combination with lenalidomide and dexamethasone for the treatment of adult patients with multiple myeloma who have received at least one prior therapy. Ixazomib was evaluated in one, randomised, double-blind, phase III study comparing ixazomib plus lenalidomide and dexamethasone (n=360; ixazomib arm) versus placebo plus lenalidomide and dexamethasone (n=362; placebo arm) in adult patients with relapsed and/or refractory multiple myeloma who had received at least one

Characteristics and Outcomes of Patients with Partial Do Not Resuscitate Orders in a Large Community Hospital.

Background Formal writing of do not resuscitate (DNR) orders first appeared in the literature in the late 20th century. Recently, providers have also noticed the presence of partial DNR orders while caring for patients. We sought to determine the effect of these orders on the clinical outcomes of the patients. Methods The study was a retrospective chart review covering a period of approximately 30 months. Patients included in the study were over 18 years of age and had a partial DNR order (i.e., chemical code, do not defibrillate (DND), do not intubate (DNI), intubate only, no cardiopulmonary

Bromelain has significant clinical benefits after extraction of the third molar during chemotherapy in patients with hematologic tumor.

The purpose of this study was to investigate the application of bromelain in the treatment of pain, swelling, and limited mouth opening in patients with hematologic tumor after extraction of the third molar during chemotherapy. We recruited 72 patients with hematologic tumor who were treated by oral and maxillofacial surgery in our hospital, and third molar extraction was performed under local anesthesia. After extraction, patients in the control group were treated with cold - hot compress and patients in the experimental group were treated by oral administration of bromelain. One, three, and

Therapeutic effects of autologous hematopoietic stem cell transplantation in multiple myeloma patients.

The present study aimed to evaluate the effect of autologous hematopoietic stem cell transplantation (ASCT) on the response and outcome of patients with multiple myeloma (MM) and to analyze the factors influencing the prognosis of the disease. Retrospective analysis was performed in 27 patients with MM who had been treated by ASCT (ASCT group) and 28 patients treated with combined chemotherapy only (non-ASCT group) from May 2004 to August 2011. The impact on the depth of response, progression-free survival (PFS) and overall survival (OS) times, as well as associated prognostic factors of patie

Hepcidin: A useful marker in chronic obstructive pulmonary disease.

PurposeThis study was designed to evaluate the levels of hepcidin in the serum of patients with chronic obstructive pulmonary disease (COPD).MethodsIn the study, 74 male patients (ages 45-75) in a stable period for COPD were grouped as Group I: Mild COPD (n:25), Group II: Moderate COPD (n:24), and Group III: Severe COPD (n:25). Healthy non-smoker males were included in Group IV (n:35) as a control group. The differences of hepcidin level among all the groups were examined.
