Patients Age 40 Years and Younger With Multiple Myeloma Have the Same Prognosis as Older Patients: An Analysis of Real-World Patients' Evidence From Latin America.

Purpose: Multiple myeloma (MM) is a highly heterogeneous, incurable disease most frequently diagnosed in the elderly. Therefore, data on clinical characteristics and outcomes in the very young population are scarce.

Patients And Methods: We analyzed clinical characteristics, response to treatment, and survival in 103 patients with newly diagnosed MM age 40 years or younger compared with 256 patients age 41-50 years and 957 patients age 51 years or older.

Real-World Evidence of Epidemiology and Clinical Outcomes in Multiple Myeloma, Findings from the Registry of Hemato-Oncologic Malignancies in Colombia, Observational Study.

Introduction/background: Multiple Myeloma (MM) is a plasma cell derived clonal disorder that represents around 1% of all newly diagnosed neoplasms. Limited data regarding MM treatment in Latin America is available, and access to novel agents for a substantial portion of the population is limited by their high costs.

Materials (or Patients) And Methods: RENEHOC is a bidirectional (retrospective and prospective) multicenter observational registry of hematological malignancies in Colombia.

Reactivation of Chagas disease after autologous hematopoietic stem cell transplantation.

Chagas disease (CD) is a protozoan zoonosis caused by Trypanosoma cruzi. Reactivation of CD occurs via drug-induced immunosuppression before and during transplantation. Here, we report the case of a 62-year-old man diagnosed with classic Hodgkin lymphoma who received highly aggressive conditioning chemotherapy before undergoing stem cell transplantation (SCT).

Autologous hematopoietic stem cell transplantation in a patient with refractory seropositive myasthenia gravis: A case report.

Myasthenia gravis is a neuromuscular autoimmune disease characterized by fatigable weakness of skeletal muscles that results from an antibody-mediated immunological attack directed at acetylcholine postsynaptic receptors. Autologous hematopoietic stem cell transplantation is considered as a treatment option in refractory cases of myasthenia gravis. A 56-year-old Colombian male presented with six months of progressive hoarseness and dysphagia, with a positive repetitive stimulation test suggestive of end plate neuromuscular disease.

Involvement of cytochrome P450 in cisplatin treatment: implications for toxicity.

Purpose: The aim of this study is to evaluate the relationship between the CYP450 enzyme family and cisplatin toxicity.

Methods: This article examined a collection of studies suggesting that CYP450 enzymes may influence cisplatin toxicity. We performed a narrative mini-review.

Anti-atherogenic and anti-angiogenic activities of polyphenols from propolis.

Propolis is a polyphenol-rich resinous substance extensively used to improve health and prevent diseases. The effects of polyphenols from different sources of propolis on atherosclerotic lesions and inflammatory and angiogenic factors were investigated in LDL receptor gene (LDLr-/-) knockout mice. The animals received a cholesterol-enriched diet to induce the initial atherosclerotic lesions (IALs) or advanced atherosclerotic lesions (AALs).

Taurine concentration in human gliomas and meningiomas: tumoral, peritumoral, and extratumoral tissue.

Taurine concentrations were determined in gliomas from 16 patients and in meningiomas from 15 patients. After imaging analysis and clinical evaluation to consider the level of functional deterioration by the scale of Karnosky, tissue was obtained by surgery. Tumoral, peritumoral and extratumoral samples were taken and analyzed by HPLC with fluorescence detector.
