Inactivated whole-virion SARS-CoV-2 vaccines and long-term clinical outcomes in patients with coronary atherosclerosis disease in China: a prospective cohort study
CONCLUSIONS: Our results indicated no evidence of an increased ischemic or bleeding risk after vaccination with inactivated SARS-CoV-2 vaccine among Chinese patients with CAD, with limited statistical power.PMID:36756815 | DOI:10.1093/cvr/cvad031

The U.S. Still Doesn ’ t Have Good COVID-19 Data. Here ’ s Why That ’ s a Problem
Check the COVID-19 Data Tracker from the U.S. Centers for Disease Control and Prevention (CDC), and you’ll get a rundown of the latest case numbers, hospitalizations, and deaths. Those categories might seem straightforward, but the data, say many experts, are telling us a lot less than we think they are. That’s because it’s getting increasingly difficult to parse who is hospitalized or dies from COVID-19, and who is hospitalized or dies from another reason but with COVID-19. Across the U.S., “COVID-19 hospitalizations” represent all kinds of patients: those who need hospital-level care for sev...

FDA Experts Vote to Make All COVID-19 Vaccines and Boosters Bivalent
In a unanimous decision, all 21 voting members of the U.S. Food and Drug Administration’s (FDA) vaccine committee recommended that the U.S. start using the same COVID-19 virus strain in all of the COVID-19 vaccines, including primary and booster doses. That means the bivalent booster dose, which targets both the original SARS-CoV-2 strain and the Omicron BA.4/5 strains, would soon become the only type used for all primary shots and boosters. The decision reflects a turning point in the pandemic. Until now, vaccine makers have tried to keep up with constantly evolving variants, but they’ve always been a few step...

A case of ischemic stroke and transient thrombocytopenia in a young female following adenoviral vector-based COVID-19 vaccination: Was the association incidental or causal?
We report a 23-year-old healthy female who developed seizures, altered sensorium, and left hemiparesis, 20 days after receiving the first dose of adenoviral vector-based COVID-19 vaccine "Covishield™." The patient had transient thrombocytopenia. The D-dimer level was 2460 ng/mL. Magnetic resonance imaging (MRI) demonstrated occlusion of M2 segment of the middle cerebral artery and cerebral infarction. Platelet factor-4 antibodies level was normal. Treatment with aspirin and antiepileptic drugs resulted in a remarkable recovery. This is the first Indian case report of ischemic stroke and transient thrombocytopenia followi...

Neurological Complications and Consequences of the Novel Coronavirus COVID-19 Infection in Elderly and Senile Patients (Literature Review)
AbstractBased on available publications, the article systematizes information about some forms of lesions of the central nervous system (CNS), their pathogenesis and clinical manifestations in the case of COVID-19. The risk factors, mechanisms of development, diagnostic approach, and the age characteristics of patients with neurological complications of COVID-19 are discussed. The specific mechanisms of the neuroinvasiveness and neurovirulence of the SARS-CoV-2 virus, regardless of the age of patients and the presence of risk factors, lead to systemic damage to the endothelium of small-caliber vessels, generalized thrombov...

Prognostic factors for mortality, intensive care unit and hospital admission due to SARS-CoV-2: a systematic review and meta-analysis of cohort studies in Europe
Eur Respir Rev. 2022 Nov 2;31(166):220098. doi: 10.1183/16000617.0098-2022. Print 2022 Dec 31.ABSTRACTBACKGROUND: As mortality from coronavirus disease 2019 (COVID-19) is strongly age-dependent, we aimed to identify population subgroups at an elevated risk for adverse outcomes from COVID-19 using age-/gender-adjusted data from European cohort studies with the aim to identify populations that could potentially benefit from booster vaccinations.METHODS: We performed a systematic literature review and meta-analysis to investigate the role of underlying medical conditions as prognostic factors for adverse outcomes due to sever...

Hereditary thrombotic thrombocytopenic purpura and COVID-19: Impacts of vaccination and infection in this rare disease
DISCUSSION: The risk of an acute episode triggered by COVID-19 seems higher than following vaccination in hTTP patients, who can be safely vaccinated against SARS-CoV-2.PMID:36284639 | PMC:PMC9585384 | DOI:10.1002/rth2.12814

Molecules, Vol. 27, Pages 6823: Elucidation of Binding Features and Dissociation Pathways of Inhibitors and Modulators in SARS-CoV-2 Main Protease by Multiple Molecular Dynamics Simulations
ojun Xu COVID-19 can cause different neurological symptoms in some people, including smell, inability to taste, dizziness, confusion, delirium, seizures, stroke, etc. Owing to the issue of vaccine effectiveness, update and coverage, we still need one or more diversified strategies as the backstop to manage illness. Characterizing the structural basis of ligand recognition in the main protease (Mpro) of SARS-CoV-2 will facilitate its rational design and development of potential drug candidates with high affinity and selectivity against COVID-19. Up to date, covalent-, non-covalent inhibitors and allosteric modulators ha...

Carotid free-floating thrombus during COVID-19 vaccine era: causality or not?
AbstractCarotid free-floating thrombus (FFT) is very rarely diagnosed in patients with acute ischemic stroke. It is a real clinical emergency due to the significant risk of death associated with thromboembolic complications. Herein, we present three patients with ischemic stroke caused by carotid FFT after less than 20  days from administration of mRNA vaccine BNT162b1 (Pfizer/BioNTech) for Severe Acute Respiratory Syndrome—CoronaVirus 2 (SARS-CoV-2). To our knowledge, these are the first cases reporting carotid FTT following SARS-CoV-2 vaccination.
