Objective: To evaluate the medical knowledge regarding the application of the diagnostic criteria for brain death and to correlate it with training parameters for this diagnosis according to Federal Council of Medicine resolution 2,173 of 2017.
Method: We interviewed 174 physicians with experience with comatose patients. A structured questionnaire adapted from previous studies was used. The associations of the variables were tested using the chi-square test for independence. A multivariate logistic model was fitted for associations with p values ≤ 0.20.
Results: Among the interviewees, 40% had been working for more than 1 year in intensive care, and 23% had initiated ten or more brain death protocols complying with the new resolution. Forty-five percent of the interviewees reported having difficulty following the criteria, 94% acknowledged the need for complementary tests for diagnosis, and 8% of them reported the existence of incorrect tests. The difficulty with these criteria decreased with an increase in the number of years of medical training (OR = 0.487; p = 0.045; 95%CI 0.241 - 0.983) and with a higher number of initiated brain death protocols (OR = 0.223; p = 0.0001; 95%CI 0.117 - 0.424).
Conclusions: Difficulties in the application of brain death criteria were identified by a significant portion of the sample. However, among other factors, more years of training and a greater number of initiated brain death protocols were associated with greater ease in the application of brain death criteria according to the guidelines provided in Resolution 2,173 of the Federal Council of Medicine.

Organ transplants are used to treat many end-stage diseases, but a shortage of donors means many patients cannot be treated. Xenogeneic organs have become an important part of filling the donor gap. Many current studies of kidney, heart, and liver xenotransplantation have used gene-edited pig organs on brain-dead recipients.

Background: Our aim was to develop a quantitative model for immediately estimating the risk of death and/or brain injury in late-onset sepsis (LOS) in preterm infants, based on objective and measurable data available at the time sepsis is first suspected (i.e., time of blood culture collection).

It has been reported that the nervous system can regulate immune reactions through various mechanisms. However, the role of splenic sympathetic nerve activity in the autoimmune reactions during the pathogenesis of experimental autoimmune encephalomyelitis (EAE) remained unclear. Here, we blocked the activity of the splenic sympathetic nerve and found that the number of adaptive immune cells, such as CD4 T cells, CD8 T cells and B cells, were upregulated.

Temozolomide is universally used to treat glioblastoma due to its unique ability to cross the blood-brain barrier and inhibit tumor growth through DNA alkylation. However, over time, the inevitable emergence of resistance to temozolomide impedes successful treatment of this cancer. As a result, there is an urgent need to identify new therapeutic targets to improve treatment outcomes for this malignancy.

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by cognitive decline and memory loss. A critical aspect of AD pathology is represented by oxidative stress, which significantly contributes to neuronal damage and death. Microglia and astrocytes, the primary glial cells in the brain, are crucial for managing oxidative stress and supporting neuronal function.
