Mesenchymal STRO-1/STRO-3+ precursor cells for the treatment of chronic heart failure with reduced ejection fraction.

The heart is susceptible to proinflammatory and profibrotic responses after myocardial injury, leading to further worsening of cardiac dysfunction. Important developments in the management of heart failure with reduced ejection fraction have reduced morbidity and mortality; however, these therapies focus on optimizing cardiac function through hemodynamic and neurohormonal pathways and not by repairing the underlying cardiac injury. The potential of cell-based therapy to reverse cardiac injury has received substantial attention. Herein are examined the phase II and III studies of bone marrow-derived mesenchymal STRO-1+ or STRO-1/STRO-3+ precursor cells in patients with ischemic and nonischemic heart failure with reduced ejection fraction, addressing the safety and efficacy of cell-based therapy throughout multiple clinical trials, the optimal dose and the steps toward revolutionizing the treatment of heart failure.

Heart disease can occur due to the blockage of blood flow to the heart muscle (heart attack). This damage reduces heart function, in part because of inflammation and fibrosis (scarring). Over time, these problems lead to heart failure and death. Advances in treating heart disease focus on maintaining heart function rather than healing the heart. A cell-based treatment designed to actually repair the heart has been used with some success. In this approach, stem cells are extracted from the bone marrow of a healthy adult, processed and then injected into a patient's diseased heart. This approach is promising, but heart repair remains incomplete. This article looks at a specific type of bone marrow stem cell that has been used as a treatment for patients with heart disease. This cell treatment was recently tested in the largest such study and the first phase III clinical trial to date in the area ­ the DREAM-HF study. This article addresses the safety and best dosage of these cells and examines how this new approach of cell-based therapy might change how heart disease is treated.

La reactividad constitucional del sujeto: una piedra de rosetta interdisciplinaria / A reatividade constitucional do sujeito. Uma pedra de roseta interdisciplinar / Subject’s constitutional reactivitya: interdisciplinary rosetta stone

Aprender a identificar de manera integral, mixta y dinámica la constitución de un sujeto significa, por un lado, ayudarlo a autoconocerse en su manera de reaccionar (por eso se habla de reactividad constitucional y no más de biotipos o rasgos), de desarrollarse (madurar o destruirse), de relacionarse y aceptar a los demás tal como son; por otro lado, sirve para personalizar diagnóstico, terapia y pronóstico. La historia del constitucionalismo y un esquema sinóptico interdisciplinario (filosofía griega, teología, medicina hipocrática, galénica, homeopática, china, ayurvédica y holística, biología, embriología, bioquímica, fisiopatología, neurología, endocrinología, psicología y espiritualidad) muestra una precisa correspondencia y un denominador común sobre la base de la teoría constitucional embriológica que habla de endoblasto, mesoblasto y ectoblasto. Una coherencia que dura por más de 24 siglos en occidente y pasa también las barreras culturales (oriente y occidente) y paradigmáticas (biomedicina y homeopatía), no puede ser casual.

To learn to identify in an integral, mixed and dynamic way the subject’s constitution means, on one hand, to help him to a self-knowledgement of his reactive way (for this, we speak of constitutional reactivity and no more of biotipe or trait), to develop himself (to mature or to destroy), to join and accept the others like they are; on the other way, it serve to personalize diagnosis, therapy and prognosis. The constitution history and a synoptic interdisciplinary diagram (Greek philosophy, theology, hippocratic, galenic, homeopatic, chinese, ayurvedic and holistic medicines, biology, embriology, biochemistry, physiopathology, neurology, endocrinology, psychology and spirituality) shows a precise link and a common denominator according to an embriologic constitutional theory, that speaks about endoblast, mesoblast and ectoblast. A coherence thas lasts for more than 24 centuries in occident and goes through even the cultural borders (eastern and western world) and paradigmatic logics (biomedicine and homeopaty) cannot be casual.
