Special Issue Information

Dear Colleagues, 

Stroke remains a global leading cause of death and permanent disability. Ischemic stroke (about 85% of all strokes) accounts for around 6.5 million deaths per year and by 2030 will result in the annual incidence of over 200 million cases of death or disability globally. Nowadays, pharmacological reperfusion therapies based on the use of the recombinant tissue plasminogen activator (rtPA), a protein involved in the breakdown of blood clots, remains the routine treatment during the acute phase of ischemic stroke (therapeutic window ≤4.5 h). However, rtPA-based treatment is only applicable to <10–30% of patients due to hemorrhagic transformation risk, and toxicity. Alternatively, recanalization could be carried out via mechanical thrombectomy with a total incidence of <20%. This opens opportunities for the reevaluation of the entire chain of stroke care delivery, including prevention, diagnosis, neuroprotection, and neuroreparation in the context of the neurovascular unit.

The present Special Issue welcomes papers on ischemic stroke, with special focus on, but not limited to, preclinical and clinical studies whose results could pave the way for prevention, accurate diagnostics, as well as effective neuroprotection. A non-exclusive list of topics includes the improvement of recanalization therapies, new thrombolytic agents, and reevaluation of neuroprotective compounds in the light of new standards for rigorous preclinical testing. Finally, research works based on molecular imaging or new biomarkers for diagnosis, prognosis, and evaluation of ischemic damage are suitable for this issue.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The circadian system regulates numerous physiological variables, including body temperature. Additionally, a circadian patter has been described in stroke onset. Considering this, we hypothesised that the chronobiology of temperature may have an impact on stroke onset and functional outcomes. We also studied the variation of blood biomarkers according to stroke onset time. This is a retrospective observational study. Of the patients included, 2763 had a stroke between midnight and 8:00 h; 1571 between 8:00–14:00 h; and 655 between 14:00 h and midnight. Axillary temperature was measured at admission. At this time, blood samples were collected for biomarker analysis (TNF-α, IL-1β, IL-6, IL-10, and glutamate). Temperature was higher in patients admitted from 8:00 h to midnight (p < 0.0001). However, the percentage of poor outcome at 3 months was highest in patients from midnight to 8:00 h (57.7%, p < 0.001). The association between temperature and mortality was highest during night time (OR: 2.79; CI 95%: 2.36–3.28; p < 0.001). These patients exhibited high glutamate (220.2 ± 140.2 µM), IL-6 (32.8 ± 14.3 pg/mL) and low IL-10 (9.7 ± 14.3 pg/mL) levels. Therefore, temperature chronobiology could have a significant impact on stroke onset and functional outcome. Superficial body hyperthermia during sleep seems to be more dangerous than during wakefulness. Further studies will be necessary to confirm our data. Full article
