Frentizole, a Nontoxic Immunosuppressive Drug, and Its Analogs Display Antitumor Activity via Tubulin Inhibition.

Antimitotic agents are one of the more successful types of anticancer drugs, but they suffer from toxicity and resistance. The application of approved drugs to new indications (i.e., drug repurposing) is a promising strategy for the development of new drugs. It relies on finding pattern similarities: drug effects to other drugs or conditions, similar toxicities, or structural similarity. Here, we recursively searched a database of approved drugs for structural similarity to several antimitotic agents binding to a specific site of tubulin, with the expectation of finding structures that could f

The Onco-Nephrology Field: The Role of Personalized Chemotherapy to Prevent Kidney Damage.

In recent years, the onco-nephrology field has acquired a relevant role in internal medicine due to the growing number of cases of renal dysfunction that have been observed in cancer patients. This clinical complication can be induced by the tumor itself (for example, due to obstructive phenomena affecting the excretory tract or by neoplastic dissemination) or by chemotherapy, as it is potentially nephrotoxic. Kidney damage can manifest as acute kidney injury or represent a worsening of pre-existing chronic kidney disease. In cancer patients, physicians should try to set preventive strategies

Drug-Induced Periocular and Ocular Surface Disorders: An EAACI Position Paper.

Various systemic and topical medications can induce ocular and periocular cutaneous adverse effects (AEs), ranging from mild to severe. These AEs may lead to ocular surface (OS) damage and, in some cases, life-threatening complications. Drug-induced ocular adverse reactions are generally classified into two primary categories: toxic reactions and/or allergic hypersensitivity reactions, which can be IgE or non-IgE-mediated. Systemic antibiotics, antivirals, and anticonvulsants can trigger adverse reactions that may involve the OS. Drugs like antihistamines, beta-blockers, antipsychotics, antide

Ligand-Gated Ion Channels as Targets for Treatment and Management of Cancers.

Ligand-gated ion channels are an ionotropic receptor subtype characterized by the binding of an extracellular ligand, followed by the transient passage of ions through a transmembrane pore. Ligand-gated ion channels are commonly subcategorized into three superfamilies: purinoreceptors, glutamate receptors, and Cys-loop receptors. This classification is based on the differing topographical morphology of the receptors, which in turn confers functional differences. Ligand-gated ion channels have a diverse spatial and temporal expression which implicate them in key cellular processes. Given that t

Yerba Mate (Ilex paraguariensis) Ameliorates Experimental Autoimmune Encephalomyelitis by Modulating Regulatory T Cell Function.

Background/Objectives: In Latin America, yerba mate (YM) is a popular infusion processed from the leaves and stems of Ilex paraguariensis. YM has been shown to have anti-inflammatory properties in several studies, although the effect of YM on multiple sclerosis (MS) remains elusive. The purpose of this study was to examine the effect of YM on the development of MS, by using the experimental autoimmune encephalomyelitis (EAE) mouse model while also evaluating its effect over infiltration of immune cells into the central nervous system (CNS) and regulatory T cell (Treg) function. Methods: YM or

Treating Primary Aldosteronism-Induced Hypertension: Novel Approaches and Future Outlooks.

Primary aldosteronism (PA) is the most common cause of secondary hypertension and is associated with increased morbidity and mortality when compared with blood pressure-matched cases of primary hypertension. Current limitations in patient care stem from delayed recognition of the condition, limited access to key diagnostic procedures, and lack of a definitive therapy option for nonsurgical candidates. However, several recent advances have the potential to address these barriers to optimal care. From a diagnostic perspective, machine-learning algorithms have shown promise in the prediction of P

Rhabdomyolysis secondary to COVID-19 infection and vaccination: a review of literature.

Rhabdomyolysis (RML), characterized by the breakdown of skeletal muscle fibers and the release of muscle contents into the bloodstream, has emerged as a notable complication associated with Coronavirus disease 2019 (COVID-19) infection and vaccination. Studies have reported an increased incidence of RML in individuals with severe COVID-19 infection. However, the exact mechanisms remain unclear and are believed to involve the host's immune response to the virus. Furthermore, RML has been documented as a rare adverse event following COVID-19 vaccination, particularly with mRNA vaccines. Proposed

Total allowable concentrations of monomeric inorganic aluminum and hydrated aluminum silicates in drinking water.

Maximum contaminant levels are used to control potential health hazards posed by chemicals in drinking water, but no primary national or international limits for aluminum (Al) have been adopted. Given the differences in toxicological profiles, the present evaluation derives total allowable concentrations for certain water-soluble inorganic Al compounds (including chloride, hydroxide, oxide, phosphate and sulfate) and for the hydrated Al silicates (including attapulgite, bentonite/montmorillonite, illite, kaolinite) in drinking water. The chemistry, toxicology and clinical experience with Al ma

The Kaleidoscope of Polyautoimmunity: An Odyssey of Diagnostic Dilemmas.

Diagnostic accuracy is of the utmost importance, both in the clinical setting and for research purposes. Mixed connective tissue disease (MCTD), rheumatoid arthritis (RA), Sjogren's syndrome (SS), and overlap syndrome (OS) frequently exhibit symptoms that mimic those of other conditions. Unfortunately, there is no singular definitive test for diagnosing these connective tissue diseases (CTDs), necessitating the reliance on expert opinions. Further complicating the matter, these diseases have overlapping clinical and serological features, and some individuals with one autoimmune disease may dev

Beyond fluid overload: uncovering the hidden causes of dyspnea in hemodialysis patients.

BACKGROUND: Shortness of breath is a common and complex symptom in patients with advanced kidney failure treated with hemodialysis. It may result from excess fluid accumulation, cardiac dysfunction, or impaired lung performance. We studied the interactions between hydration status, pulmonary function, and muscle strength. METHODS: This cohort study included 29 patients on maintenance hemodialysis. Each participant underwent lung function testing, diffusing capacity for carbon monoxide measurement, handgrip strength assessment, body composition analysis by bioimpedance, echocardiography, and l

Disappearance of femoral head shortly after femoral neck fracture: a case report and literature review.

This case report describes a woman in her 70s who presented with a 3-month history of hip pain and inability to walk. Upon admission, she was diagnosed with the extremely rare condition of complete femoral head disappearance. A comprehensive examination was conducted to determine the cause and devise an effective treatment strategy, taking the patient's medical history into account. Through interdisciplinary discussions, occult infection and other potential causes were ruled out. The femoral head disappearance was ultimately determined to be due to wear, ischemia, and absorption following a fr

Hypercalcemia in Cancer: Causes, Effects, and Treatment Strategies.

Calcium plays central roles in numerous biological processes, thereby, its levels in the blood are under strict control to maintain homeostatic balance and enable the proper functioning of living organisms. The regulatory mechanisms ensuring this balance can be affected by pathologies such as cancer, and as a result, hyper- or hypocalcemia can occur. These states, characterized by elevated or decreased calcium blood levels, respectively, have a significant effect on general homeostasis. This article focuses on a particular form of calcium metabolism disorder, which is hypercalcemia in neoplasm

Anakinra: efficacy in the management of fever during neutropenia and mucositis in autologous stem cell transplantation (AFFECT-2)-study protocol for a multicenter randomized double-blind placebo-controlled trial.

BACKGROUND: Since decades, fever and infections have been the most important complications of intensive chemotherapy and hematopoietic stem cell transplantation (HSCT) in the treatment of hematologic malignancies. Neutropenia has long been considered to be the most important risk factor for these complications. However, recent studies have shown that not neutropenia, but the development of mucositis is the most important cause of these complications. Currently, limited options for the prevention and treatment of mucositis are available, of which most are only supportive. The pro-inflammatory c

Compartment Syndrome of All Extremities in the Setting of COVID-19-Induced Systemic Capillary Leak Syndrome With Superimposed Myositis.

Three years following the pandemic's emergence, COVID-19 has continued to affect much of the symptomatic population with widely varied respiratory complaints, fevers, numerous unexpected prodromal manifestations, and unknown long-term consequences. Scattered cases involving myopathies, rhabdomyolysis, and compartment syndrome have also been reported throughout the pandemic. Some similar cases have been attributed to systemic capillary leak syndrome (SCLS). Here, we report the development of compartment syndrome involving all extremities in a 57-year-old vaccinated female known to have COVID-19

The Role of Cullin-RING Ligases in Striated Muscle Development, Function, and Disease.

The well-orchestrated turnover of proteins in cross-striated muscles is one of the fundamental processes required for muscle cell function and survival. Dysfunction of the intricate protein degradation machinery is often associated with development of cardiac and skeletal muscle myopathies. Most muscle proteins are degraded by the ubiquitin-proteasome system (UPS). The UPS involves a number of enzymes, including E3-ligases, which tightly control which protein substrates are marked for degradation by the proteasome. Recent data reveal that E3-ligases of the cullin family play more diverse and c
