ABSTRACT Natural Killer cells are immune leukocytes required for responses against tumor cells and virus-infected cells. In the last decade, natural killer cells have emerged as promising tools in cancer therapy, and clinical studies on patients treated with natural killer cells have revealed increased rates of disease-free survival. In this article, we review results from the major clinical trials that have used natural killer cells for cancer treatment, including their global distribution. We also discuss the major mechanisms of natural […]

ABSTRACT Hematopoiesis is characterized by the differentiation and maturation of multipotent stem cells into hematopoietic cells. Common lymphoid progenitor cells differentiate into B and T lymphocytes; natural killer cells can also originate from common lymphoid progenitors. In recent years, a cellular subtype of lymphocytes, called innate lymphocytes, has been described. Innate lymphoid cells (ILCs) play an important effector and regulatory role in innate immunity, and similar to natural killer cells, depend on the γc and Id2 chains for their development. […]

ABSTRACT Objective: MicroRNAs are small non-coding RNAs that are abundantly expressed in various biofluids, making them promising candidates for cancer biomarkers. This review aims to present current evidence on the use of miRNA as biomarkers for the non-invasive diagnosis of bladder cancer. Methods: A systematic literature review, using the Medline database, was performed in July 2022 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. All articles were required to satisfy the risk-of-bias assessment using the Joanna […]

ABSTRACT Circulatory shock is a common fatal condition. Despite this, information on this syndrome in the current medical literature is fragmented and esoteric. Adherence to each basic element of care can have a profound impact on patient outcomes. Disturbances in pumping (cardiogenic), content/container relationship (hypovolemic and vasoplegic), or blockage in blood circulation (obstructive) can induce tissue hypoperfusion, causing hemodynamic shock. If not quickly reversed, hypoperfusion progresses to irreversible multi-organ failure. The course can be fatal even before reaching this stage […]

ABSTRACT Objective To evaluate the psychiatric alterations resulting from deep brain stimulation of the subthalamic nucleus in the management of Parkinson’s disease. Methods Articles were searched using three databases: Public/Publisher MEDLINE, Virtual Health Library, and Cochrane Library. Results Eleven studies were included in the analysis. Manic syndrome alone was reported in two of the 11 studies analyzed. Psychosis alone was not reported in any of them, but it was found in association with other psychiatric alterations in two studies, not […]

ABSTRACT Introduction Chronic kidney disease is a progressive and irreversible loss of kidney function and considerably affects the lives of patients and their families. Its high incidence necessitates efficient public policies for prevention and treatment. However, policies for chronic kidney disease education and awareness are scarce. Objective To evaluate global public policies for the prevention and treatment of chronic kidney disease adopted in various regions, aiming to comprehend the differences between various models. Methods This integrative review followed PRISMA recommendations […]

ABSTRACT Objective This work aims to review the existing use of robotics in plastic surgery. Methods A meticulous selection process identified 22 articles relevant to this scoping review. Results The literature on the use of robotics in plastic surgery is sparse. Nonetheless, this review highlights emerging benefits in microsurgery, breast reconstruction, and transoral surgery. Conclusion This scoping review identifies critical articles reporting the emerging use of robotics in plastic surgery. While the scientific medical community has yet to extensively document […]

ABSTRACT Objective: To identify, synthesize, and analyze the scientific knowledge produced regarding the implications of using clinical simulation for undergraduate nursing or medical students’ motivation for learning. Methods: The search for articles was conducted between July 28 and August 3, 2022, on the PubMed/MEDLINE, Scopus, Web of Science, and SciELO databases. The following was used for the search: P – undergraduate students attending Nursing or Medicine courses; C – motivation for learning, and C – skills and clinical simulation laboratory. […]

ABSTRACT Objective To review the long-term outcomes (functional status and psychological sequelae) of survivors of critical illnesses due to epidemic viral pneumonia before the COVID-19 pandemic and to establish a benchmark for comparison of the COVID-19 long-term outcomes. Methods This systematic review of clinical studies reported the long-term outcomes in adults admitted to intensive care units who were diagnosed with viral epidemic pneumonia. An electronic search was performed using databases: MEDLINE®, Web of Science™, LILACS/IBECS, and EMBASE. Additionally, complementary searches […]

ABSTRACT Heart failure is the leading cause of cardiac-related hospitalizations. Limited access to reevaluations and outpatient appointments restricts the application of modern therapies. Telemedicine has become an essential resource in the healthcare system because of its countless benefits, such as higher and more frequent appointments and faster titration of medications. This narrative review aimed to demonstrate the evidence and unresolved issues related to the use of telemedicine in patients with heart failure. No studies have examined heart failure prevention; however, […]
