Anesthesia and Alzheimer & #39;s: A review
Jeffrey Y SunJournal of Anaesthesiology Clinical Pharmacology 2020 36(3):297-302 As early as 1955, it was Bedford who provided description of cognitive changes in elderly patients following anesthesia and surgery. Reports of individuals with catastrophic, non-stroke-related decline in cognitive functions following anesthesia and surgery lead to a perception in the lay population that anesthesia and surgery have the potential to greatly exaggerate the progression of dementia, particularly Alzheimer's disease (AD). There is a concern that anesthesia and surgery could cause irreversible impairment, leading to AD. ...

Reduction of Leukocyte Microvascular Adherence and Preservation of Blood-Brain Barrier Function by Superoxide-Lowering Therapies in a Piglet Model of Neonatal Asphyxia
Conclusion: Using three different strategies to either prevent formation or enhance elimination of O2⋅_ during the post-asphyxial period, we saw both reduced leukocyte adherence and preserved BBB function with treatment. These findings suggest that agents which lower O2⋅_ in brain may be attractive new therapeutic interventions for the protection of the neonatal brain following asphyxia. Introduction Asphyxia is a relatively common source of neonatal brain damage (1), affecting ~2 in every 1,000 births (2). The hypoxic ischemia resulting from this oxygen deprivation can produ...

Associations of Anemia With Outcomes in Patients With Spontaneous Intracerebral Hemorrhage: A Meta-Analysis
Conclusions: Anemia on admission was associated with higher mortality and an increased risk of poor outcome in patients with ICH. However, the results were limited by the high heterogeneity of included studies. Prospective, multi-center or population-based, large sample cohort studies are needed in the future. Introduction Intracerebral hemorrhage (ICH) is the second most common cause of stroke and a highly lethal disease (1), which still lacks effective therapeutic interventions (2, 3). Although age, baseline ICH volume and neurological status on admission are well-known predictors of outcome of ICH (4), none of t...

Apelin-13 Suppresses Neuroinflammation Against Cognitive Deficit in a Streptozotocin-Induced Rat Model of Alzheimer ’s Disease Through Activation of BDNF-TrkB Signaling Pathway
Conclusion The data in this manuscript demonstrates that apelin-13 upregulates BDNF against STZ-induced congnitive impairment by suppressing glial cell activity and inflammatory factors release. This suggests apelin signaling may be a new target in the treatment of AD. Ethics Statement All experimental protocols were carried out according to the National Institutes of Health Guide for the Care and Use of Laboratory Animals approved by the Central South University at XiangYa Animal Care and Use Committee. Author Contributions XqQ and LH conceived the study and contributed to its experimental design. HqL carried out the...

Imaging of Blood-Brain Barrier Disruption by Tc-99m-Tilmanocept Molecular Imaging of a Rodent Model of Traumatic Brain Injury
Conclusions: These results are consistent with the hypothesis that microglial cells bearing CD206 trap fluorescent-labeled Tc-99m-tilmanocept in regions of BBB disruption. This provides the motivation for a clinical trial of intra-venously administered Tc-99m-tilmanocept with the goal of developing a SPECT/CT protocol for the detection of neuro-inflammation.

Acute effects of electro-acupuncture (EA) on hippocampal long term potentiation (LTP) of perforant path-dentate gyrus granule cells synapse related to memory.
Authors: He X, Yan T, Chen R, Ran D Abstract Acupuncture, a traditional Chinese therapeutic method, has been widely used in clinical practice to treat diseases such as stroke, Bell's palsy, Alzheimer disease, Parkinson diseases, dysmenorrhea and chronic pain. Mounting lab data had suggested that electro-acupuncture could alleviate dementia and restore long term potentiation of hippocampus in rat. Clinical data also indicated that electro-acupuncture could improve electrical activity of brain in vascular dementia patients. However, its biological basis and acute effects on hippocampal long term potentiation (LTP) re...

Age-Dependent Neurovascular Dysfunction and Damage in a Mouse Model of Cerebral Amyloid Angiopathy Basic Sciences
Conclusions— Tg-SwDI mice exhibit a profound age-dependent cerebrovascular dysfunction, involving multiple regulatory mechanisms. Early in the disease process, oxidative stress is responsible for most of the vascular dysfunction, but with advancing disease structural alterations of the vasomotor apparatus also play a role. Early therapeutic interventions are likely to have the best chance to counteract the deleterious vascular effects of cerebral amyloid angiopathy.

Test could give two-year warning for Alzheimer's
Conclusion The researchers suggest that Alzheimer's disease can be predicted with an accuracy of 87.5% when thinning of the cortex in the right anterior cingulated gyrus is seen on MRI, alongside test results suggesting problems with recall and recognition. This research does not indicate a new "test", as MRI and psychological testing are standard procedures when investigating the signs and symptoms of dementia. What is novel in this approach is looking at a specific combination of results as a potential way of predicting which people with MCI may develop Alzheimer's disease. While this form of testing would be b...

Increased risk of dementia in people with previous exposure to general anesthesia: A nationwide population-based case-control study.
CONCLUSIONS: A history of previous exposure to surgery under GA might be associated with an increased risk of dementia, particularly in subjects who have undergone repeated exposure to GA. In addition, subjects who had received surgery under ETGA with comorbidities such as stroke, hypertension, diabetes mellitus, and atherosclerosis could have a potential relationship with dementia risk.
