AI Article Synopsis
- The study aimed to explore how echocardiogram results, ferritin levels, C-reactive protein, and leukocyte counts relate to poor outcomes in pediatric sepsis patients.
- A prospective cohort study included children aged 28 days to 18 years who had sepsis and required prolonged mechanical ventilation and vasoactive drugs; key indicators were measured over 72 hours.
- Results showed that higher ferritin levels and signs of cardiac dysfunction were linked to longer hospital stays, more extended mechanical ventilation, and a higher inotropic agent usage, indicating worse health outcomes for the patients.
Article Abstract
Objective: The aim of this study was to verify the association of echocardiogram, ferritin, C-reactive protein, and leukocyte count with unfavorable outcomes in pediatric sepsis.
Methods: A prospective cohort study was carried out from March to December 2014, with pediatric critical care patients aged between 28 days and 18 years. Inclusion criteria were diagnosis of sepsis, need for mechanical ventilation for more than 48h, and vasoactive drugs. Serum levels of C-reactive protein, ferritin, and leukocyte count were collected on the first day (D0), 24h (D1), and 72h (D3) after recruitment. Patients underwent transthoracic echocardiography to determine the ejection fraction of the left ventricle on D1 and D3. The outcomes measured were length of hospital stay and in the pediatric intensive care unit, mechanical ventilation duration, free hours of VM, duration of use of inotropic agents, maximum inotropic score, and mortality.
Results: Twenty patients completed the study. Patients with elevated ferritin levels on D0 had also fewer ventilator-free hours (p=0.046) and higher maximum inotropic score (p=0.009). Patients with cardiac dysfunction by echocardiogram on D1 had longer hospital stay (p=0.047), pediatric intensive care unit stay (p=0.020), duration of mechanical ventilation (p=0.011), maximum inotropic score (p=0.001), and fewer ventilator-free hours (p=0.020).
Conclusion: Cardiac dysfunction by echocardiography and serum ferritin value was significantly associated with unfavorable outcomes in pediatric patients with sepsis.

Mitochondrial DNA (mtDNA) is highly polymorphic, and host mtDNA variation has been associated with altered cancer severity. To determine the basis of this mtDNA-cancer association, we analyzed conplastic mice with the C57BL/6J (B6) nucleus but two naturally occurring mtDNA lineages, and , where mitochondria generate more oxidative phosphorylation (OXPHOS)-derived reactive oxygen species (mROS). In a cardiac transplant model, Foxp3+ T regulatory (Treg) cells supported long-term allograft survival, whereas Treg cells failed to suppress host T effector (Teff) cells, leading to acute rejection.

Mitochondrial endonuclease G (EndoG) contributes to chromosomal degradation when it is released from mitochondria during apoptosis. It is presumed to also have a mitochondrial function because EndoG deficiency causes mitochondrial dysfunction. However, the mechanism by which EndoG regulates mitochondrial function is not known.

Methods: Patients with major depressive disorder, bipolar disorder and, schizophrenia and with comorbid obesity (n = 29) were assigned to a 12-week structured physical exercise program. Peripheral blood biomarkers of inflammation, oxidative stress, vascular mechanisms, and metabolic activity, as well as neurocognitive and functional performance were assessed twice, before and after intervention.

Background: Our previous studies reported that D-galactose (D-gal) administration for four to eight weeks caused metabolic disturbance, brain mitochondrial dysfunction, and brain aging, leading to cognitive dysfunction in similar with natural aging condition. Spermidine is a polyamine that can be found naturally. Spermidine has been showed the beneficial effects on various models, such as attenuating metabolic/gut impairments in obesity, and ameliorating memory loss in aged model.

Background: Alzheimer's disease (AD) is the leading cause of dementia in elderly humans worldwide. More than 40 million people currently suffer from AD, and this prevalence tends to increase considerably in the coming decades due to increased longevity. The unfolded protein response (UPR) is an adaptive signaling mechanism that aims to maintain cell viability under misfolded protein accumulation and endoplasmic reticulum stress.
