Evaluating the performance of the PRISMA-7 frailty criteria for predicting disability and death after acute ischemic stroke
Stroke is the second cause of death and disability in the world, affecting close to 14 million people globally per year and being responsible for around 120 million disability-adjusted life years.1,2 More deaths occur worldwide because of stroke than AIDS, tuberculosis, and malaria combined.3 Therefore, being able to identify which individuals with stroke are at highest risk of poor function and mortality is critically important given the need for weighing the risks, costs, and benefits of interventions during various shared decision-making processes.

Pharmacological and cardiovascular perspectives on the treatment of COVID-19 with chloroquine derivatives.
Abstract The novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19) and an ongoing severe pandemic. Curative drugs specific for COVID-19 are currently lacking. Chloroquine phosphate and its derivative hydroxychloroquine, which have been used in the treatment and prevention of malaria and autoimmune diseases for decades, were found to inhibit SARS-CoV-2 infection with high potency in vitro and have shown clinical and virologic benefits in COVID-19 patients. Therefore, chloroquine phosphate was first used in the treatment of COVID-19 in China. Later, under a lim...

Chloroquine pretreatment attenuates ischemia-reperfusion injury in the brain of ob/ob diabetic mice as well as wildtype mice.
In conclusion, chloroquine pretreatment could reduce cerebral damage after ischemic stroke especially in diabetic mice through multiple mechanisms, which include reducing neural cell DNA injury, restoring euglycemia and anti-inflammatory effects. The findings may provide potential for the development of chloroquine in the prevention and treatment of stroke in diabetic high-risk patients. PMID: 31647899 [PubMed - as supplied by publisher]

Activated protein C in neuroprotection and malaria
Purpose of review Activated protein C (APC) is a homeostatic coagulation protease with anticoagulant and cytoprotective activities. Focusing on APC's effects in the brain, this review discusses three different scenarios that illustrate how APC functions are intimately affecting the physiology and pathophysiology of the brain. Recent findings Cytoprotective APC therapy holds promise for the treatment of ischemic stroke, and a recently completed trial suggested that cytoprotective-selective 3K3A-APC reduced bleeding in ischemic stroke patients. In contrast, APC's anticoagulant activity contributes to brain bleeding as s...

Bioinformatics analysis of a long non ‑coding RNA and mRNA regulation network in rats with middle cerebral artery occlusion based on RNA sequencing.
Bioinformatics analysis of a long non‑coding RNA and mRNA regulation network in rats with middle cerebral artery occlusion based on RNA sequencing. Mol Med Rep. 2019 May 27;: Authors: Duan X, Han L, Peng D, Peng C, Xiao L, Bao Q, Peng H Abstract Long non‑coding RNAs (lncRNAs) have been proven to be critical gene regulators of development and disease. The main aim of the present study was to elucidate the lncRNA‑mRNA regulation network in ischemic stroke induced by middle cerebral artery occlusion (MCAO) using RNA sequencing (RNA‑seq) in rats. lncRNA expression profiles were screened in brain ti...

Endocrine Disruptors and Health Effects in Africa: A Call for Action
Conclusion: To address the many challenges posed by EDCs, we argue that Africans should take the lead in prioritization and evaluation of environmental hazards, including EDCs. We recommend the institution of education and training programs for chemical users, adoption of the precautionary principle, establishment of biomonitoring programs, and funding of community-based epidemiology and wildlife research programs led and funded by African institutes and private companies. https://doi.org/10.1289/EHP1774 Received: 16 February 2017 Revised: 22 May 2017 Accepted: 24 May 2017 Published: 22 August 2017 Address correspond...

Stroke in sickle cell anemia patients: A need for multidisciplinary approaches
Abstract: Sickle cell anemia (SCA) is an autosomal recessive disorder, with Mendelian inheritance pattern, caused by a missense mutation in the β-polypeptide chain of the hemoglobin B. SCA preferentially affects populations in countries where malaria was/is present (e.g. Africa, USA, Brazil). Thereby, in USA, the incidence of SCA is relatively high, around 1/500, and the prevalence is about 1/1000. In Brazil, SCA represents a major public health problem with an incidence ranging from 1/2000 to 1/600 depending on the regions. Homozygotic patients present more severe medical conditions and reduced life expectancy than heter...

Nitrone-based Therapeutics for Neurodegenerative Diseases. Their use alone or in Combination with Lanthionines.
Abstract The possibility of free radical reactions occurring in biological processes led to the development and employment of novel methods and techniques focused on determining their existence and importance in normal and pathological conditions. For this reason the use of Nitrones for spin trapping free radicals came into widespread use in the 1970s and 1980s when surprisingly the first evidence of their potent biological properties was first noted. Since then wide-spread exploration and demonstration of the potent biological properties of phenyl-tert-butylnitrone (PBN) and derivatives were shown in preclinical ...
