Calcium intake and the risk of stroke: an up-dated meta-analysis of prospective studies.
CONCLUSIONS: Dairy calcium intake is inversely associated with stroke incidence. There is a non-linear dose-response relationship between calcium intake and stroke risk. However, when the follow-up time is long enough, the inverse relationship is independent of dose. Additional large cohort studies are required to illustrate this relationship in detail.

Calcium supplements linked to post-stroke dementia in women
Conclusion The media paint this as a troubling study for older women who take calcium to strengthen their bones. However the small size of the study (only 98 women took calcium supplements, and only 14 of those got dementia) and its observational nature mean that we cannot rely on the results. As the researchers mention, it is possible that those taking supplements were less healthy than those that didn't in some unmeasured way. Further research may improve our confidence in these results. Broken bones are not a trivial matter for older people – a broken hip can be the difference between being able to live independentl...

Molecular profile of the rat peri-infarct region four days after stroke: Study with MANF.
In this study, we examine the molecular profile of the peri-infarct region on post-stroke day four, time when reparative processes are ongoing. We used a multiomics approach, involving RNA sequencing, and mass spectrometry-based proteomics and metabolomics to characterize molecular changes in the peri-infarct region. We also took advantage of our previously developed method to express transgenes in the peri-infarct region where self-complementary adeno-associated virus (AAV) vectors were injected into the brain parenchyma on post-stroke day 2. We have previously used this method to show that mesencephalic astrocyte-derived...

Preventing development of post-stroke hyperexcitability by optogenetic or pharmacological stimulation of cortical excitatory activity
Neurobiol Dis. 2023 Jul 17:106233. doi: 10.1016/j.nbd.2023.106233. Online ahead of print.ABSTRACTStroke is the most common cause of acquired epilepsy, but treatment for preventing the development of post-stroke epilepsy is still unavailable. Since stroke results in neuronal damage and death as well as initial loss of activity in the affected brain region, homeostatic plasticity may be trigged and contribute to an increase in network hyperexcitability that underlies epileptogenesis. Correspondingly, enhancing brain activity may inhibit hyperexcitability from enhanced homeostatic plasticity and prevent post-stroke epileptoge...

Micro RNA 181c-5p: a promising target for post-stroke recovery in socially isolated mice
Publication date: Available online 10 November 2019Source: Neuroscience LettersAuthor(s): Maria Antony, Victoria Scranton, Pranay Srivastava, Rajkumar VermaAbstractDysregulation of microRNAs (miRNAs) has been tied to several neurological disorders, including ischemic stroke. It has also been established that social environments can modulate miRNA profiles. We have previously shown that post-stroke social isolation (SI) is linked to poor stroke outcomes and that miR-181c-5p emerged as one of few lead miRNAs that was downregulated in both stroke and SI. Therefore, in this study we examined the potential role of miR-181c-5p m...

Association between serum calcium levels and first stroke: A community-based nested case-control study
ConclusionsOur results suggested a U-shaped association between serum calcium and first stroke; both low and high serum calcium levels were associated with an increased risk of the first stroke in the Chinese population.

Podcast: Cerebrolysin for acute ischaemic stroke
When someone has an acute ischemic stroke, urgent and reliable treatments will reduce their risks of disability or dying from their brain tissue damage. The treatments used vary around the world, and a drug called cerebrolysin is widely used in post-Soviet countries, Eastern Europe, Central and Southeast Asia. In April 2017, the latest update of this review was published by researchers from Kazan Federal University in Russia and Chinara Razzakova, a PhD student from the university interviewed one of the authors, Liliya Eugenevna, for this podcast." This Cochrane Review is about a medicine called cerebrolysin, which is used...

Serum lipoprotein(a) and risk of hemorrhagic stroke among incident peritoneal dialysis patients: a large study from a single center in China.
Conclusions: Among patients with incident PD, a higher serum Lp(a) level may predict a lower risk of hemorrhagic stroke. PMID: 31498021 [PubMed - in process]

Drug treatment strategies for osteoporosis in stroke patients.
Authors: Hsieh CY, Sung SF, Huang HK Abstract Introduction: Osteoporosis and subsequent fractures are well-recognized complications of stroke. However, drug treatment strategies for osteoporosis after stroke have been rarely discussed in the current guidelines for the management of stroke or osteoporosis.Areas covered: The authors review the epidemiology, characteristics, pathophysiology, and risk prediction of post-stroke osteoporosis and fractures. Then they provide an overview of existing evidence regarding drug treatment strategies for osteoporosis in stroke patients. They also review the effects on bone minera...

Thoracic Aortic < sup > 18 < /sup > F-Sodium Fluoride Activity and Ischemic Stroke in Patients With Established Cardiovascular Disease
CONCLUSIONS: In patients with established cardiovascular disease, thoracic aortic 18F-sodium fluoride activity is associated with the progression of atherosclerosis and future ischemic stroke. Arterial 18F-sodium fluoride activity identifies localized areas of atherosclerotic disease activity that are directly linked to disease progression and downstream regional clinical atherothrombotic events.

Dietary calcium intake and risk of stroke: a dose-response meta-analysis.
CONCLUSION: These findings suggest that dietary calcium intake may be inversely associated with stroke in populations with low to moderate calcium intakes and in Asian populations. PMID: 23553167 [PubMed - in process]

FDG PET Imaging as A Non-invasive Method to Demonstrate Peri-infarct Depression after Stroke
Conclusion: FDG PET imaging is reliable to reflect metabolic stress imposed by peri-infarct depression. Peri-infarct depression leads to the metabolic change in neurons, including suppression of mitochondria function and overactivation of glycolysis, thus deteriorate functional and tissue consequence. The insults from PID could be alleviated by improving mitochondria function.
