Livedoid vasculopathy: A multidisciplinary clinical approach to diagnosis and management.

Livedoid vasculopathy (LV) is a rare, chronic, and occlusive disease of the veins supplying the upper parts of the skin. The pathogenesis of the disease is not precisely understood, and its attacks are often unpredictable but tend to worsen during the summer. LV affects women more often. This increased risk for LV in women might be related to sex-specific physiological conditions, such as pregnancy, or a higher incidence of LV-associated conditions, such as connective tissue diseases, hypercoagulable states, and venous stasis in women. The typical clinical appearance of LV consists of three ma

New PET Radiotracers for the Imaging of Neuroendocrine Neoplasms.

Opinion statementNeuroendocrine neoplasms (NEN) are a heterogeneous group of tumours derived from cells of neuroendocrine origin and can potentially arise everywhere in the human body. The diagnostic assessment of NEN can be performed using a variety of PET radiopharmaceuticals. Well-differentiated NEN (NET) present a high expression of SSTR (somatostatin receptors) and can therefore be studied with 68Ga-DOTA-peptides ([68Ga]Ga-DOTANOC, [68Ga]Ga-DOTATOC, [68Ga]Ga-DOTATATE). Current guidelines recommend the use of SSTR imaging to assess disease extension at staging/restaging, follow-up, assessm

Pharmacologic management of bone-related complications and bone metastases in postmenopausal women with hormone receptor-positive breast cancer.

There is a high risk for bone loss and skeletal-related events, including bone metastases, in postmenopausal women with hormone receptor-positive breast cancer. Both the disease itself and its therapeutic treatments can negatively impact bone, resulting in decreases in bone mineral density and increases in bone loss. These negative effects on the bone can significantly impact morbidity and mortality. Effective management and minimization of bone-related complications in postmenopausal women with hormone receptor-positive breast cancer remain essential. This review discusses the current underst

Advances in Drug Delivery and Biomaterials: Facts and Vision.

Drug delivery and biomaterials are different fields of science but, at the same time, are tightly related and intertwined. The 2018 CRS Italy Chapter Annual Workshop aims to explore recent advances in design and development in these areas. Many colleagues from Europe participated to the Workshop, stimulating the discussion. To foster the discussion on recent research and networking opportunities, especially among younger attendees, all poster-presenting authors were asked to provide a short talk. The very friendly and stimulating atmosphere allowed the attendees to explore new frontiers and ta

Pyoderma gangrenosum: pathogenetic mechanisms and their implications for treatment.

Pyoderma gangrenosum (PG) is a rare inflammatory skin disease belonging to the group of neutrophilic dermatoses. The pathogenesis of PG involves a predisposing genetic background that facilitates a dysregulated innate and adaptive immune response, with an imbalance between pro-inflammatory and anti-inflammatory mediators, leading to neutrophil-driven inflammatory damage. Several immunosuppressants and immunomodulatory drugs are currently available for the treatment of PG, in combination with topical therapies, wound management and pain control strategies. Systemic corticosteroids and cyclospor

CPUY201112, a novel synthetic small-molecule compound and inhibitor of heat shock protein Hsp90, induces p53-mediated apoptosis in MCF-7 cells.

Heat-shock protein 90 (Hsp90) is highly expressed in many tumor cells and is associated with the maintenance of malignant phenotypes. Targeting Hsp90 has had therapeutic success in both solid and hematological malignancies, which has inspired more studies to identify new Hsp90 inhibitors with improved clinical efficacy. Using a fragment-based approach and subsequent structural optimization guided by medicinal chemistry principles, we identified the novel compound CPUY201112 as a potent Hsp90 inhibitor. It binds to the ATP-binding pocket of Hsp90 with a kinetic dissociation (Kd) constant of 27

Combination treatment of dupilumab with bortezomib in a patient with IgG kappa gammopathy of renal significance, uremic pruritus and chronic lichenoid dermatitis.

Chronic pruritus (CP) is one of the most frequent symptoms among dermatological conditions, capable of reducing the quality of life (QoL). CP may be induced by atopic dermatitis or other dermatological and/or non-dermatological conditions. In this article, we report the case of a patient affected by generalized CP, characterised by multiple papulo-nodular and escoriatic lesions, developed after the onset of an immunoglobulin G (IgG) kappa monoclonal gammopathy of renal significance (MGRS), associated with renal insufficiency. Therefore, a combined treatment with dupilumab for CP and bortezomib

The potential of mesenchymal stem cells in the management of radiation enteropathy.

Although radiotherapy is effective in managing abdominal and pelvic malignant tumors, radiation enteropathy is still unavoidable. This disease severely affects the quality of life of cancer patients due to some refractory lesions, such as intestinal ischemia, mucositis, ulcer, necrosis or even perforation. Current drugs or prevailing therapies are committed to alleviating the symptoms induced by above lesions. But the efficacies achieved by these interventions are still not satisfactory, because the milieus for tissue regeneration are not distinctly improved. In recent years, regenerative ther

ObjectiveThe present study aimed to evaluate the short-term clinical performance and safety of percutaneous microwave ablation (MWA) techniques for the treatment of bone tumors.MethodsThis single-institution retrospective study investigated 47 cases of bone tumors treated by MWA from June 2015 to June 2018. The study included 26 patients (55.3%) with benign bone tumors and 21 patients (44.7%) with malignant bone tumors. The tumors were located in the spine or sacrum (15, 31.9%), the upper extremities (6, 12.8%), the lower extremities (17, 36.2%) and the pelvis (9, 19.1%). Outcomes regarding cl

Нацеливание экспорта эндоплазмического ретикулума нарушает метаболическую устойчивость в множестве миэломы.

Множественная миелома (ММ) характеризуется производством и секрецией большого количества иммуноглобулинов, в результате чего эта злонамеренность в значительной степени зависит от механизмов, которые поддерживают клеточный протеостаз. Несмотря на значительный клинический прогресс, достигнутый в области деградативной ветки протеостаза, гораздо меньше внимания уделяется биосинтетической ветке. В этом исследовании мы продемонстрировали, что сдерживание экспорта эндоплазмического ретикулума (ER), зависящего от COPII, приводит к смерти клеток в нескольких линиях ММ и основных клеток, созданных пацие

Study of a novel Ca/P/S-based cement implanted in the osteoporotic goat spine and its clinical application in preventing adjacent vertebral fractures.

Osteoporotic vertebral compression fracture (OVCF) has been increasing over the last decades. In addition to primary OVCF, the adjacent vertebral fracture (AVF) is a frequent serious complication in OVCF patients receiving percutaneous vertebroplasty or kyphoplasty, resulting in poor long-term outcome and recurrent symptoms. The aim of the present study is to investigate the bone regeneration behavior of a novel Ca/P/S-based resorbable cement (Ezechbone® Cement CBC-400) implanted into surgically created vertebral defects of ovariectomized (OVX) goats. Furthermore, the present study provides a

ZHX2 inhibits diabetes-induced liver injury and ferroptosis by epigenetic silence of YTHDF2.

ObjectiveMetabolic dysfunction-associated steatotic liver disease (MASLD) is a common complication of type 2 diabetes mellitus (DM). The transcription factor zinc fingers and homeoboxes 2 (ZHX2) has been implicated in the pathogenesis of chronic liver diseases, yet its precise role and underlying mechanism in DM-induced hepatic injury remain poorly elucidated.MethodsTo investigate this, we used a high-fat diet (HFD) and streptozotocin (STZ) administration to create a DM model in mice, while high glucose (HG) exposure was used to simulate DM in vitro. Through various experiments such as lucifer

Current Trends and Challenges in the Clinical Translation of Nanoparticulate Nanomedicines: Pathways for Translational Development and Commercialization.

The use of nanotechnology in medicine has the potential to have a major impact on human health for the prevention, diagnosis, and treatment of diseases. One particular aspect of the nanomedicine field which has received a great deal of attention is the design and development of nanoparticulate nanomedicines (NNMs) for drug delivery (i.e., drug-containing nanoparticles). NNMs are intended to deliver drugs via various mechanisms: solubilization, passive targeting, active targeting, and triggered release. The NNM approach aims to increase therapeutic efficacy, decrease the therapeutically effecti

Эволюция антиCD20 Лечения множественных склерозов: оптимизация характеристик и функций антител.

Истощение клеток B с помощью целевых агентов CD20 обычно используется для лечения множественных склерозов (MS), других аутоиммунных заболеваний и некоторых гематологов. Первоначальный очевидный успех с ритуксимабом в использовании MS и нейромиелитной оптики стимулировал развитие антиCD20 моноклональной антителной (mAb) терапии oprelizumab, atumumab и ublituximab, а также антиCD19 mAb inebilizumab. Хотя каждая из них является эффективной в плане целеопределения и истощения элементов В, структурные различия превращаются в различные механизмы действий, влияющие на поддержание истощения и безопасн
