Osteoporosis in Frail Patients: A Consensus Paper of the Belgian Bone Club.

In this consensus paper, the Belgian Bone Club aims to provide a state of the art on the epidemiology, diagnosis, and management of osteoporosis in frail individuals, including patients with anorexia nervosa, patients on dialysis, cancer patients, persons with sarcopenia, and the oldest old. All these conditions may indeed induce bone loss that is superimposed on physiological bone loss and often remains under-recognized and under-treated. This is of particular concern because of the major burden of osteoporotic fractures in terms of morbidity, mortality, and economic cost. Therefore, there is

Hepatocellular carcinoma stem cells: the current state of small molecule-based inhibitors.

Hepatocellular carcinoma (HCC) is the most common type of liver cancer, accounting for over 90% of all cases. Patients with advanced-stage HCC are referred to systemic treatment. Although some advances in HCC therapy have been made in recent years, the prognosis for patients remains poor due to drug resistance, tumor relapse, and metastasis, implying that overall survival remains a challenge. Many studies have shown that tumor-initiating stem cells, also known as cancer stem cells (CSCs), play essential roles in tumorigenesis, metastasis, and treatment resistance in HCC and that future cancer

The role of heat shock protein 90 in idiopathic pulmonary fibrosis: state of the art.

Heat shock protein 90 (HSP 90) and its isoforms are a group of homodimeric proteins that regulate several cellular processes, such as the elimination of misfolded proteins, cell development and post-translational modifications of kinase proteins and receptors. Due to its involvement in extracellular matrix (ECM) remodelling, myofibroblast differentiation and apoptosis, HSP 90 has been investigated as a key player in the pathogenesis of lung fibrosis. Idiopathic pulmonary fibrosis (IPF) is the most common and deadly interstitial lung disease, due to the progressive distortion of lung parenchyma

Pro-inflammatory cytokine-mediated anemia: regarding molecular mechanisms of erythropoiesis.

Anemia of cancer and chronic inflammatory diseases is a frequent complication affecting quality of life. For cancer patients it represents a particularly bad prognostic. Low level of erythropoietin is considered as one of the causes of anemia in these pathologies. The deficiency in erythropoietin production results from pro-inflammatory cytokines effect. However, few data is available concerning molecular mechanisms involved in cytokine-mediated anemia. Some recent publications have demonstrated the direct effect of pro-inflammatory cytokines on cell differentiation towards erythroid pathway,

Preclinical Evaluation of a Lentiviral Vector for Huntingtin Silencing.

Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder resulting from a polyglutamine expansion in the huntingtin (HTT) protein. There is currently no cure for this disease, but recent studies suggest that RNAi to downregulate the expression of both normal and mutant HTT is a promising therapeutic approach. We previously developed a small hairpin RNA (shRNA), vectorized in an HIV-1-derived lentiviral vector (LV), that reduced pathology in an HD rodent model. Here, we modified this vector for preclinical development by using a tat-independent third-generation LV (pCCL) ba

Insulin-Like Growth Factor 2 mRNA-Binding Protein 3 Modulates Aggressiveness of Ewing Sarcoma by Regulating the CD164-CXCR4 Axis.

Ewing sarcoma (EWS) is the second most common bone and soft tissue-associated malignancy in children and young adults. It is driven by the fusion oncogene EWS/FLI1 and characterized by rapid growth and early metastasis. We have previously discovered that the mRNA binding protein IGF2BP3 constitutes an important biomarker for EWS as high expression of IGF2BP3 in primary tumors predicts poor prognosis of EWS patients. We additionally demonstrated that IGF2BP3 enhances anchorage-independent growth and migration of EWS cells suggesting that IGF2BP3 might work as molecular driver and predictor of E

Antibodies to watch in 2026.

The Antibodies to Watch article series provides annual updates on commercial late-stage clinical development, regulatory review, and marketing approvals of antibody therapeutics. Since the first article was published in 2010, the late-stage pipeline has grown from 26 antibody therapeutics to over 200, while during the same time numerous molecules in late-stage studies either transitioned to regulatory review and were approved or were terminated. In this installment of the series, we recap first marketing approvals granted to 19 antibody therapeutics in 2025, discuss 26 molecules currently in r

Targeting inflammation as cancer therapy.

Inflammation has accompanied human beings since the emergence of wounds and infections. In the past decades, numerous efforts have been undertaken to explore the potential role of inflammation in cancer, from tumor development, invasion, and metastasis to the resistance of tumors to treatment. Inflammation-targeted agents not only demonstrate the potential to suppress cancer development, but also to improve the efficacy of other therapeutic modalities. In this review, we describe the highly dynamic and complex inflammatory tumor microenvironment, with discussion on key inflammation mediators i

Holistic Approach to the Diagnosis and Treatment of Patients with Tumor Metastases to the Spine.

The treatment of neoplastic spine metastases requires multi-faceted assessment and an interdisciplinary approach to patients. The metastases do not show specific symptoms but are often the first confirmation of the presence of a primary tumor in a patient. The diagnostic process includes imaging and invasive procedures, e.g., biopsy. It is essential to qualify the patient for an appropriate treatment using dedicated scales. Decompression of the spinal cord is a critical issue to save or restore neurological function in a patient with spine metastases. Surgical treatment ought to meet three cri

Protein breakdown in muscle wasting: role of autophagy-lysosome and ubiquitin-proteasome.

Skeletal muscle adapts its mass as consequence of physical activity, metabolism and hormones. Catabolic conditions or inactivity induce signaling pathways that regulate the process of muscle loss. Muscle atrophy in adult tissue occurs when protein degradation rates exceed protein synthesis. Two major protein degradation pathways, the ubiquitin-proteasome and the autophagy-lysosome systems, are activated during muscle atrophy and variably contribute to the loss of muscle mass. These degradation systems are controlled by a transcription dependent program that modulates the expression of rate-lim

Bone metastases in thyroid cancer.

Whereas preemptive screening for the presence of lymph node and lung metastases is standard-of-care in thyroid cancer patients, bone metastases are less well studied and are often neglected in thyroid cancer patient surveillance. Bone metastases in thyroid cancer are, however, independently associated with poor/worse prognosis with a median overall survival from detection of only 4 years despite an otherwise excellent prognosis for the vast majority of thyroid cancer patients. In this review we summarize the state of current knowledge as pertinent to bony metastatic disease in thyroid cancer,

Humanized Bone Model Identifies BMP6 as a Multifunctional Regulator in Myeloma Bone Disease.

Multiple myeloma (MM) is a plasma cell malignancy that disrupts bone homeostasis by suppressing osteogenesis and promoting osteoclast activity. While most therapeutic interventions to date have focused on targeting tumor cells and reducing osteolysis, we investigate whether osteoinductive strategies can restore bone formation and counteract disease progression. Using a human bone marrow-like scaffold model that enables direct in vivo evaluation of tumor-stroma interactions and human bone formation, we demonstrate that MM-derived mesenchymal stromal cells (MSCs) retain osteogenic potential but

Осколки периферальной крови, полученные в результате ТРНК, являются новыми неинвазивными биомаркерами для диагностики и прогнозируемой стратификации в множестве миеломы.

В последнее время в качестве критически важных регуляторов в области онкологической биологии появились небольшие РНК, полученные в результате передачи РНК; однако их профили экспрессии и клиническая значимость в нескольких миеломах (ММ) по-прежнему плохо определены. МЕТОДЫ: Секвенирование высокой производительности было проведено для всеобъемлющей характеристики профилей выражения ТСНК в периферийных моноядерных клетках крови (ПБМК) из 22 новые пациенты с диагнозом MM и 19 здоровый контроль. Общие целевые гены были предсказаны путем интеграции MiRanda и TookScan, и была создана сеть взаимодейс

От диагностики к лечению: изучение механизмов, лежащих в основе оптического неврата в множестве склерозов.

Множественный склероз (MS) — хроническое аутоиммунное заболевание, воздействующее на центральную нервную систему, которое, как правило, вызывает сенсорные расстройства, моторную слабость, слабую походку, несогласованность и оптический неуриит (ON). Согласно статистическим данным, до 50% пациентов, страдающих синдромом MS, испытывают проблемы со зрением в период болезни, страдающие от нечеткого зрения, боли, недостатка зрения и даже слепоты. Лечение перешло от кортикостероидов к лечению, ориентированному на клетки В/Т. В рамках этого обзора проводится всеобъемлющая и систематическая оценка диаг

Mechanisms inducing low bone density in Duchenne muscular dystrophy in mice and humans.

Patients affected by Duchenne muscular dystrophy (DMD) and dystrophic MDX mice were investigated in this study for their bone phenotype and systemic regulators of bone turnover. Micro-computed tomographic (µCT) and histomorphometric analyses showed reduced bone mass and higher osteoclast and bone resorption parameters in MDX mice compared with wild-type mice, whereas osteoblast parameters and mineral apposition rate were lower. In a panel of circulating pro-osteoclastogenic cytokines evaluated in the MDX sera, interleukin 6 (IL-6) was increased compared with wild-type mice. Likewise, DMD patie

Поврежденное когнитивное и поведенческое функционирование в детском возрасте и экономические результаты взрослой жизни.

Метформин был назван следующим: one :: из наиболее важных медицинских агентов первой линии в управлении типом 2 Болит диабет. Поскольку метформин является главным образом антигипергликемическим агентом, он также оказывает огромное влияние на различные системы и процессы. Он действует главным образом путем активации AMPK (Adenosine Monophosphate-Activated Protein Kinase) в клетках и сокращения выхода глюкозы из печени. Кроме того, она сокращает производство современных продуктов гликации и реактивных видов кислорода в эндотелии, помимо регулирования глюкозы и липидного метаболизма в кардиомиоки

Bisphosphonate Treatment Ameliorates Chemotherapy-Induced Bone and Muscle Abnormalities in Young Mice.

Chemotherapy is frequently accompanied by several side effects, including nausea, diarrhea, anorexia and fatigue. Evidence from ours and other groups suggests that chemotherapy can also play a major role in causing not only cachexia, but also bone loss. This complicates prognosis and survival among cancer patients, affects quality of life, and can increase morbidity and mortality rates. Recent findings suggest that soluble factors released from resorbing bone directly contribute to loss of muscle mass and function secondary to metastatic cancer. However, it remains unknown whether similar mech

INTRODUCTION: Although current international guidelines provide comprehensive evidence-based guidance for the management of pulmonary hypertension, clinicians are still regularly faced with uncertainty regarding correct diagnosis and optimal treatment. METHODS: Ten diagnostic and management dilemmas were formulated by a panel of experts in the field of pulmonary hypertension. Current evidence was reviewed and a practical approach suggested for each dilemma. RESULTS: Diagnostic and management dilemmas discussed include pulmonary hypertension with high cardiac output, idiopathic pulmonary arte

Novel Local "Off-the-Shelf" Immunotherapy for the Treatment of Myeloma Bone Disease.

Myeloma bone disease (MBD) is one of the major complications in multiple myeloma (MM)-the second most frequent hematologic malignancy. It is characterized by the formation of bone lesions due to the local action of proliferating MM cells, and to date, no effective therapy has been developed. In this study, we propose a novel approach for the local treatment of MBD with a combination of natural killer cells (NKs) and mesenchymal stem cells (MSCs) within a fibrin scaffold, altogether known as FINM. The unique biological properties of the NKs and MSCs, joined to the injectable biocompatible fibri
