Filter by:General anesthetic induced neurotoxicity has received considerable attention in the past decade from various pre-clinical studies in rodents and non-human primates. Which demonstrated that exposure to general anesthetic agents for a longer duration can induce neuronal cell death that can lead to adverse neurodevelopmental outcomes. The neuroapoptosis and impairment of neurodevelopmental processes has been postulated as the underlying mechanism, but the molecular mechanisms was not completely understood. Various hypothesis has been proposed they are- Antagonistic effect on N-methyl-D-aspartate receptors and agonistic effect on gamma-aminobutyric acid type A receptors; mitochondrial perturbations and activation of reactive oxygen species and dysregulation of intracellular calcium homeostasis. They trigger neuroapoptosis and cell death through the activation of caspases.3 Caspases, a group of cysteine proteases, plays an important role in regulation and execution of apoptosis. Caspase-3 is most important since it is activated by many cell death signals and cleaves a variety of important cellular proteins.4 Various anesthetic agents like isoflurane, halothane, sevoflurane, nitrous oxide and propofol causes neurotoxicity by activation of caspase-3. Which has been proven from various animal studies western blot analysis, immunohistochemical analysis and flow cytometric analysis.3, 5-9 Though it is documented that exposure to general anesthetics causes neurotoxicity during active brain growth in animals, there is no evidence of such effects in adult humans.10 and it is difficult to separate the effects of anesthetics from surgical impact and other factors associated with diseases.11 The patients with aneurysmal subarachnoid hemorrhage (SAH) have variable degree of neurological insults and it is possible, based on the evidence from animal models that administration of general anesthetics could add to the neuronal insults.
Investigators will implement a novel cassava processing method (wetting method, WTM) that safely removes cyanogenic compounds from cassava flour prior to human consumption in a stratified village-cluster randomized non-inferiority trial so as to compare the effectiveness of a peer-led intervention (women training other women in the WTM) with that by community-health worker specialists.
There is considerable evidence that most general anaesthetics modulate brain development in animal studies. The impact is greater with longer durations of exposure and in younger animals. There is great controversy over whether or not these animal data are relevant to human clinical scenarios. The changes seen in preclinical studies are greatest with GABA agonists and NMDA antagonists such as volatile anaesthetics (eg sevoflurane), propofol, midazolam, ketamine, and nitrous oxide. There is less evidence for an effect with opioid (such as remifentanil) or with alpha 2 agonists (such as dexmedetomidine). Some, but not all, human cohort studies show an association between exposure to anaesthesia in infancy or early childhood and later changes in cognitive tests, school performance or risk of developing neurodevelopmental disorders. The evidence is weak due to possible confounding. A recent well designed cohort study (the PANDA study) comparing young children that had hernia repair to their siblings found no evidence for a difference in a range of detailed neuropsychological tests. In that study most children were exposed to up to two hours of anaesthesia. The only trial (the GAS trial) has compared children having hernia repair under regional or general anesthesia and has found no evidence for a difference in neurodevelopment when tested at two years of age. The GAS and PANDA studies confirm the animal data that short exposure is unlikely to cause any neurodevelopmental impact. The impact of longer exposures is still unknown. In humans the strongest evidence for an association between surgery and poor neurodevelopmental outcome is in infants having major surgery. However, this is also the group where confounding is most likely. The aim of our study is to see if a new combination of anaesthetic drugs results in a better long-term developmental outcome than the current standard of care for children having anaesthesia expected to last 2 hours or longer. Children will be randomised to receive either a low dose sevoflurane/remifentanil/dexmedetomidine or standard dose sevoflurane anaesthetic. They will receive a neurodevelopmental assessment at 3 years of age to assess global cognitive function.
A phase IV, multicentre, randomised, open-label, pilot clinical trial designed to evaluate HIV-infected, aviremic patients who receive treatment with the combination of DTG/3TC/ABC and who have neuropsychiatric adverse effects that, in the opinion of the investigators, may be related to taking DTG/3TC/ABC, if they improve after switching antiretroviral therapy to the combination of ELV/COBI/FTC/TAF.
The primary objective of this trial is to determine the impact of the FOLFOX regimen on quality of life and the incidence of chemotherapy induced neurotoxicity.
The purpose of this study is to determine whether monosialoganglioside are effective in the prevention of neurotoxicity induced by albumin-bound paclitaxel chemotherapy in lung cancer patients, and improve the quality of life of patients.
The purpose of this study is to determine whether Monosialotetrahexosylganglioside sodium injection can relieve the neurotoxicity caused by oxaliplatin in GI cancer.
To study the risk prediction of chemotherapy-induced peripheral neuropathy (CIPN) by the clinical bioinformatics and genomic profile.
Background: Taxane plays a key role in the treatment of breast cancer and taxane-induced peripheral neuropathy (TIPN) is a dose-limiting adverse effect leading to treatment discontinuation. Ganglioside-monosialic acid (GM1) functions as a neuroprotective factor. However, the effects of GM1 on TIPN in breast cancer patients remains unknown. Purpose: This randomized phase III trial is designed to evaluate the potential effects of GM1 for preventing TIPN in breast cancer patients.
This randomized phase III trial is studying glutathione to see how well it works in preventing peripheral neuropathy caused by paclitaxel and carboplatin in patients with ovarian cancer, fallopian tube cancer, and/or primary peritoneal cancer. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Chemoprotective drugs, such as glutathione, may help prevent peripheral neuropathy caused by paclitaxel and carboplatin. It is not yet known whether glutathione is more effective than a placebo in preventing peripheral neuropathy.
