Abstract
Septic encephalopathy is a sepsis-related brain dysfunction with a deterioration of cortical functions. The experimental studies in the rat brain revealed a deranged neurotransmitter proflle during septic encephalopathy. Glutamatergic synapses, essential in learning and memory, undergo use-dependent changes in synaptic strength, referred to as plasticity. Permanent strengthening of synapses after a brief stimulus, termed long-term potentiation (LTP), was discovered in the hippocampus, and here it has been most thoroughly studied. Cholinergic neurotransmission plays an important role in regulating the cognitive functions of the brain. It acts as a signal-to-noise ratio modulator of sensory and cognitive inputs. The irregularities in brain functions give rise to the symptoms of delirium, including disorganized thinking and disturbances of attention and consciousness, which in turn might affect learning and memory. Possible mechanisms for cholinergic deficiency include impairment of synaptic functions of acetylcholine. Imbalances in the cholinergic system during sepsis might therefore play an extensive role in the septic delirium.
Highlights
Autophagy is well known as one of the biogenic responses against various stresses, which possesses the beneficial roles for survival, but little is known about the dynamics and its significance during the septic condition
The aim of our study was to observe the effects of TNFα on the model of perfused rat heart
community-acquired pneumonia (CAP)-mediated antiinflammatory signals in vagal efferent nerve fibers result in the release of acetylcholine, which interacts with innate immune cells that express the nicotinic acetylcholine receptor subunit α7 (α7nAChR)
Summary
Autophagy is well known as one of the biogenic responses against various stresses, which possesses the beneficial roles for survival, but little is known about the dynamics and its significance during the septic condition. Conclusion The assessment of routine biomarkers (bilirubin, white blood cells and hemoglobin) may be a helpful tool in the decisionmaking process at the bedside, for the evaluation of early ICU admission of recoverable patients, as indicators of inflammatory response, organ dysfunction or catabolism level, and their significant predictive value on mortality. The purpose of this study was to ascertain the prognostic value of proadrenomedullin (pADM), measured in all patients admitted to the ICU of our hospital with a diagnosis of severe sepsis or septic shock during 1 year. The aim of the study is to evaluate life quality after trauma and to identify the most important needs of the patients, in order to improve the level of care after an ICU stay and to implement a faster and more effective reintegration into the active and productive society. We report the results of the baseline phase of this trial
