Role of Radiotherapy in the Era of Novel Immune-Based Treatment Strategies for Multiple Myeloma.

Radiotherapy (RT) constitutes an important treatment modality in multiple myeloma (MM), traditionally used for the management of symptomatic osteolytic and extramedullary lesions. Objectives of RT are symptom alleviation and prevention of complications such as neurological deficits and pathological fractures. Over the past decade, systemic therapy (ST) for MM has undergone substantial advancements, notably with the incorporation of monoclonal antibodies in frontline regimens, as well as the emergence of bispecific antibodies and chimeric antigen receptor T-cells (CAR-T) for relapsed and refrac

Novel diagnostic approaches and therapeutic management of mucormycosis: insights from a retrospective monocentric cohort study.

BACKGROUND: Mucormycosis is a rare, opportunistic fungal infection with high mortality rates, predominantly affecting immunocompromised patients. Its management is challenging due to diagnostic complexity and limited therapeutic options. METHODS: This retrospective cohort study analyzed 21 cases of mucormycosis diagnosed at the University Hospital of Liège between July 2018 and August 2023. Clinical, microbiological, and radiological data were evaluated to identify risk factors, treatment modalities, and outcomes. RESULTS: Hematological malignancies (82%) and immunosuppressive therapy (53%)

The Glucocorticoid Receptor: Isoforms, Functions, and Contribution to Glucocorticoid Sensitivity.

Glucocorticoids exert pleiotropic effects on all tissues to regulate cellular and metabolic homeostasis. Synthetic forms are used therapeutically in a wide range of conditions for their anti-inflammatory benefits, at the cost of dose and duration-dependent side effects. Significant variability occurs between tissues, disease states, and individuals with regard to both the beneficial and deleterious effects. The glucocorticoid receptor (GR) is the site of action for these hormones and a vast body of work has been conducted understanding its function. Traditionally, it was thought that the anti-

Нейростероиды и неврологические расстройства.

Нейростероиды играют важную роль в качестве эндогенных нейромодуляторов, которые производятся на местном уровне в центральной нервной системе и быстро изменяют взрываемость нейронов и активацию микроглиальных клеток и астроцитов. Здесь мы рассматриваем механизмы синтеза, метаболизма и действия нейростероидов в центральной нервной системе. Нейростероиды могут играть различные роли в центральной нервной системе в физиологических условиях, связывая их с мембранными ионными каналами и рецепторами, такими, как рецепторы гамма-аминобутирной кислоты типа А, рецепторы Nметил-D-асортатных рецепторов, к

Hypercalcemia-Associated Hodgkin's Lymphoma Presenting as Normal Pressure Hydrocephalus: A Case Report.

Hodgkin's lymphoma is a malignancy of the lymphatic system that can rarely present with advanced-stage features such as spinal cord involvement and hypercalcemia. We present the case of a 63-year-old Caucasian male with advanced Hodgkin's lymphoma, presenting with hypercalcemia and symptoms resembling normal pressure hydrocephalus. The patient exhibited gait impairment, altered mental status, and urinary incontinence, forming the classic triad seen in normal pressure hydrocephalus. Laboratory findings revealed leukocytosis, anemia, hypercalcemia, and acute kidney injury. Imaging showed extensi

Orbital Onslaught: An Atypical Presentation of Mucormycosis in a Diabetic and Hypertensive Patient.

Mucormycosis, primarily known to affect the sinuses and brain, severely threatens immunocompromised individuals. Its occurrence in the orbital region is rare and potentially devastating. We report a unique case of a 50-year-old male with longstanding diabetes and hypertension who exhibited isolated orbital mucormycosis confined to the right eye. The patient presented with fever and acute vision loss without classic sinusitis symptoms; earlier mismanagement led to an aggressive relapse. An orbital computed tomography (CT) scan revealed inflammatory changes indicative of an early-stage invasive

Intrapleural Fibrinolytic Therapy With Alteplase for the Management of Multiloculated Malignant Pleural Effusion: A Case Series.

Malignant pleural effusion refers to the presence of fluid in the pleural space due to an underlying malignancy. Malignant pleural effusion is sometimes accompanied by the formation of fibrous adhesions resulting in a multiloculated effusion. This diminishes the efficacy of drainage and makes successful pleurodesis impossible, leaving the patients with severe shortness of breath. In the process of freeing the pleural space from fluid-filled loculations, intrapleural application of fibrinolytic is being investigated as a possible therapeutic approach. Here, we report four cases of adult patient

The Impact of Survival Benefit and Study Design on FDA Approval for Anticancer Drugs Over the Past Decades.

Despite the tremendous effort in the oncology community, the success rate of anticancer development remained low at 30% to 40% from the Phase 3 study to the regulatory approval. The factors associated with the regulatory approval for market authorization have gained interest in the community to improve the success rate of drug development. Using the data from 208 Phase 3 studies for anticancer drugs, we explored the possible factors associated with the US Food and Drug Administration's (FDA's) approval by multivariate logistic regression analysis. The model incorporated 21 factors from therape

A recommended practical approach to the management of target therapy and angiogenesis inhibitors cardiotoxicity: an opinion paper of the working group on drug cardiotoxicity and cardioprotection, Italian Society of Cardiology.

The US National Cancer Institute estimates that cardiotoxicity (CTX) from target therapy refers mostly to four groups of drugs: epidermal growth factor receptor 2 inhibitors, angiogenic inhibitors, directed Abelson murine leukemia viral oncogene homolog inhibitors, and proteasome inhibitors. The main cardiotoxic side-effects related to antiepidermal growth factor receptor 2 therapy are left ventricular systolic dysfunction and heart failure. Angiogenesis inhibitors are associated with hypertension, left ventricular dysfunction/heart failure, myocardial ischemia, QT prolongation, and thrombosis

The osteogenic niche-targeted arsenic nanoparticles prevent colonization of disseminated breast tumor cells in the bone.

Up to 70% of patients with late-stage breast cancer have bone metastasis. Current treatment regimens for breast cancer bone metastasis are palliative with no therapeutic cure. Disseminated tumor cells (DTCs) colonize inside the osteogenic niches in the early stage of bone metastasis. Drug delivery into osteogenic niches to inhibit DTC colonization can prevent bone metastasis from entering its late stage and therefore cure bone metastasis. Here, we constructed a 50% DSS6 peptide conjugated nanoparticle to target the osteogenic niche. The osteogenic niche was always located at the endosteum with

Innovative Approaches in Bone Tissue Engineering: Strategies for Cancer Treatment and Recovery.

Cancer has rapidly emerged as a leading global cause of premature mortality, with significant economic implications projected to reach USD 25.2 trillion from 2020 to 2050. Among the various types of cancer, primary bone cancers, though uncommon, are projected to see nearly 4000 new cases diagnosed in the United States in 2024. The complexity of treating bone cancer arises from its rarity, diversity, and the challenges associated with surgical interventions, metastatic spread, and post-operative complications. Advancements in bone tissue engineering (BTE) have introduced innovative therapeutic

Parallel Toxicities: A Comparative Analysis of Chemotherapy-Induced Neutropenia and Alopecia.

Chemotherapy-induced neutropenia (CIN) and chemotherapy-induced alopecia (CIA) are significant toxicities affecting cancer patients. CIN is a potentially fatal complication of chemotherapy caused by myelosuppression and increased infection susceptibility, while CIA, although not fatal, severely affects treatment adherence and mental health. This study provides a comprehensive comparative analysis of CIN and CIA, focusing on patient, disease, treatment, and genetic risk factors. Key risk factors for CIN and CIA include age, poor performance status, body mass index (BMI), laboratory abnormalitie

A core group of experts prepared a preliminary guideline, which was discussed, reviewed, and approved by the entire working group. The guideline provides clinical recommendations for the preventive management including prophylactic treatment of viral, bacterial, parasitic, and fungal diseases. The guideline focuses on antimicrobial

Emerging therapies for autosomal dominant polycystic kidney disease with a focus on cAMP signaling.

Autosomal dominant polycystic kidney disease (ADPKD), with an estimated genetic prevalence between 1:400 and 1:1,000 individuals, is the third most common cause of end stage kidney disease after diabetes mellitus and hypertension. Over the last 3 decades there has been great progress in understanding its pathogenesis. This allows the stratification of therapeutic targets into four levels, gene mutation and polycystin disruption, proximal mechanisms directly caused by disruption of polycystin function, downstream regulatory and signaling pathways, and non-specific pathophysiologic processes sha

Thirty years from FDA approval of pegylated liposomal doxorubicin (Doxil/Caelyx): an updated analysis and future perspective.

In 2025, it will be 30 years since the initial clinical approval of pegylated liposomal doxorubicin (PLD) by the Food and Drug Administration. PLD predated the field of nanomedicine and became a model nanomedicine setting key pharmacological principles (prolonged circulation, slow drug release and the enhanced permeability and retention (EPR) effect) for clinical application of other nano-drugs in cancer therapy. The impressive reduction of cardiotoxicity conferred by PLD is the most valuable clinical asset. While PLD has gained a strong foothold in relapsed ovarian cancer and metastatic breas

A systematic review of ongoing clinical trials in optic pathway gliomas.

INTRODUCTION: Optic pathway gliomas (OPGs), also known as Visual Pathway Gliomas, are insidious, debilitating tumours. They are most commonly WHO grade 1 pilocytic astrocytomas and frequently occur in patients with neurofibromatosis type 1. The location of OPGs within the optic pathway typically precludes complete resection or optimal radiation dosing, hence outcomes remain poor compared to many other low-grade gliomas. The aim of this systematic review was to formulate a comprehensive list of all current ongoing clinical trials that are specifically looking at clinical care of OPGs in order t
