RESUMO

INTRODUCTION: Blood transfusion is one of the most common medical practices worldwide. However, current scientific literature has shown that the immunomodulatory effects of blood transfusion are associated with an increased likelihood of infection, prolonged hospitalization, and morbimortality. Also, it means high costs for healthcare systems. METHODS: In this context, acknowledging that blood transfusions are essentially heterologous cell transplantations, the use of therapeutic options has gained strength and is collectively known as the patient blood management (PBM) program. PBM is an approach based on three main pillars: (1) treating anemias and coagulopathies in an optimized manner, especially in the preoperative period; (2) optimizing perioperative hemostasis and the use of blood recovery systems to avoid the loss of the patient's blood; (3) anemia tolerance, with improved oxygen delivery and reduced oxygen demand, particularly in the postoperative period. RESULTS: Current scientific evidence supports the effectiveness of PBM by reducing the need for blood transfusions, decreasing associated complications, and promoting more efficient and safer blood management. Thus, PBM not only improves clinical outcomes for patients but also contributes to the economic sustainability of healthcare systems. CONCLUSION: The aim of this review was to summarize PBM strategies in a comprehensive, evidence-based approach through a systematic and structured model for PBM implementation in tertiary hospitals. The recommendations proposed herein are from researchers and experts of a high-complexity university hospital in the network of the Sistema Único de Saúde, presenting itself as a strategy that can be followed as a guideline for PBM implementation in other settings.

RESUMO

BACKGROUND A blood cell saver, or autotransfusion system, is used to collect, wash, and return autologous blood collected from the surgical patient. This report describes a 55-year-old man who underwent combined mitral and aortic valve replacement surgery with cardiopulmonary bypass and had a successful outcome following intraoperative and postoperative autologous blood transfusion using a blood cell saver. CASE REPORT The patient did not accept blood transfusion for reasons of religious conscience and was in a critical condition, receiving palliative care. He needed combined mitral and aortic valve replacement surgery. The surgery was conducted using a cell saver (Sorin Xtra Autotransfusion System) in the intraoperative and postoperative periods for 24 h, to resolve this challenging case, from a technical and ethical point of view. The volume of red blood cells recovered intraoperatively was 1430 mL, with a hematocrit level of 40%, and 690 mL, with a hematocrit of 35%, in the postoperative period. Therefore, a significant volume of autologous blood was recovered. The autologous blood transfusion resulted in an excellent clinical outcome for the patient, who was discharged on the ninth postoperative day. CONCLUSIONS We can conclude that the use of a blood cell saver in cardiac surgery, in both intra- and postoperative periods, resulted in the maintenance of adequate hemoglobin and hematocrit levels, no infection postoperatively, and rapid and complete recovery of the patient. Thus, the use of the blood cell saver guaranteed the individual's autonomy to refuse blood products safely, with good clinical results, and without dependence on allogeneic blood transfusions.

RESUMO

INTRODUCTION: Several studies indicate the role of mesenchymal stem cells (MSCs) as an important tool in regenerative medicine associated with injuries that affect the central nervous system (CNS). The MSCs have the capacity to differentiate into cells of the embryonic tissue, such as the mesoderm. So, these cells can be found in a variety of tissues. Also, the MSCs can release immunomodulatory and neurotrophic factors performance as inflammation mediators operating in injured tissue regeneration. Furthermore, they can differentiate into neural-like cells in vitro. Thereby, because of the high immunomodulatory role of MSCs, this review sought to describe the main immunomodulatory mechanisms performed by MSCs in CNS recovery after tissue injury or neurodegenerative diseases. METHODS: PubMed and ScienceDirect were searched between January 2011 to March 2021, and 43 articles met the criteria of the review. RESULTS: This systematic review indicates that MSCs were used in vivo experimental multiple sclerosis, Parkinson's disease, Alzheimer's disease, amyotrophic lateral sclerosis, ischemic stroke, and traumatic brain injury. The treatment MSCs were usually from human origin, derived from bone marrow, and administered intravenously. CONCLUSION: It was shown that MSCs, independent from origin or administration pathway, can reduce inflammation and help in the recovery and preservation of injured neural tissue. Thus, the use of MSCs represents a potential therapeutic option in the treatment of neurological disorders mediated by inflammatory processes.

RESUMO

Alcoholic neuropathy (AN), a debilitating condition that mainly affects chronic alcohol drinkers, is thought to cause lesions in the peripheral nervous system leading to sensory, autonomic, and motor dysfunctions. Despite many studies, the pathogenesis of these lesions is still not completely understood. We investigated few aspects on the development of alcohol-induced peripheral neuropathy, by assessing sensory, motor and autonomic functions, as well as stereological analysis of axonal fibers and myelin sheath of the sciatic nerve. Twelve male Wistar rats were divided into Control group and Alcohol group that was submitted to Two Bottle-Choice Paradigm of intermittent and voluntary alcohol solution intake (20%; v/v) during eight weeks. At the end of treatment, three different sensorium-motor tests were applied - Tactile Sensitivity, Thermal Sensitivity, and Functional Observational Battery (FOB). Quantitative morphometric analysis of sciatic nerve structures was performed by stereological method. Alcohol concentration in the blood was measured to analyze possible correlation between availability of alcohol in the blood and the magnitude of the peripheral nerve lesion. Our data showed a peripheral effect of chronic alcohol intake associated with hyperalgesia and a process of demyelination with a strong correlation with alcohol consumption. This process was associated with increased tactile sensitivity, with behavioral reflexes such as locomotor hyperactivity, changes in gait and balance, and autonomic reflexes such as piloerection.

RESUMO

Alcohol use disorder (AUD) is a chronic and progressive disease influenced by genetic, psychosocial, and environmental factors. The consequences of alcohol consumption involve alterations in neural circuits of emotion and cognition, as well as in the motor planning circuit. Furthermore, during the natural aging process, several biochemical and functional alterations are also observed with neurological consequences. Thus, considering the consequences of chronic alcohol consumption on neural systems and natural aging process, we aimed to analyze the degree of motor and functional impairment in elderly with chronic alcohol consumption. Sixty elderly underwent an analysis of alcohol consumption profile (Alcohol Use Disorders Identification Test - AUDIT) that divided them into a control group (CON) and an alcohol group (ALC). The analysis of quality of life was performed using the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), the analysis of motor function was performed using the Borg Scale, the Six-Minute Walk Test (6MWT) and the Motor Scale for Elderly (MSE). We were able to conclude that the misuse of alcohol by the elderly promotes significant physical limitations. These limitations result in a worsening of functional capacity of walking and various dimensions of motor ability: fine motor skill, global coordination, balance, body scheme, spatial organization, temporal organization, and general motor aptitude. Besides the physical limitations caused by alcohol use, the quality of life in their physical, mental, and social aspects was reduced. Thus, actions are required to help the elderly understand these losses and exercise control over alcohol misuse.
