Individuals with neuro-post-COVID syndrome and poorer cognitive performance have a distinct immunological signature (a reduced functionality of CD8+ TEM cells correlates with high depression scores)

A Korean nationwide study conducted on more than 44 million vaccinated individuals found that the incidence of myocarditis associated with COVID vaccination was highest in males aged 12 to 17 years, and the most serious adverse effect was sudden cardiac death

Brain neurons form excitatory glutamatergic synapses with metastatic cells of non-neural cancers, mediated by AMPA glutamate receptors, with metastatic cancer cells on the postsynaptic side of the synapses

SARS-CoV-2 in vitro triggers the inflammation and senescence pathways in A9 dopaminergic neurons (mostly affected by Parkinson’s disease in the substantia nigra) derived from human pluripotent stem cells. Increased risk of viral-induced parkinsonism?

Vaccinated COVID convalescents were found to have increased T-cell activation (a selective uptake of [18F]F-AraG) in many anatomical regions (thoracic spinal cord, cauda equina, lumbar and iliac crest, bone marrow, brainstem, aortic arch, pulonary artery, lower lung lobes, pharyngeal tonsils, hilar lymphoid tissue, proximal colon wall, rectal wall, and the right heart ventricle wall) and SARS-CoV-2 spike protein RNA in rectosigmoid cells up to 2.5 years after acute infection

Elevated levels of arthroplasty-relevant metals were found in the blood and cerebrospinal fluid of individuals with arthroplasty implants

The outbreak of Ebola disease caused by Bundibugyo virus disease (BVD) in the Democratic Republic of the Congo, Kenya and Nigeria

On October 23, 2026, the World Health Organization reported the outbreak of Ebola disease caused by the Ebola Bundibugyo virus (BVD), which had expanded geographically in the Democratic Republic of the Congo, as well as in Kenya and Nigeria.

Clinical and radiological findings of cytotoxic lesions of the corpus callosum (CLOCCs) associated with COVID-19

This study presented clinical, radiological and laboratory features of cytotoxic lesions of the corpus callosum (CLOCCs) in eight COVID-19 patients.

SARS-CoV-2-related inflammation found in the epipharynx of patients with long COVID syndrome suggests the therapeutic potential of epipharyngeal abrasive therapy

These results suggest a possible link between long COVID and chronic epipharyngitis and emphasize the therapeutic potential of EAT in treating the symptoms of long COVID.

The persistence of vaccine-derived S1 protein in CD16+ monocytes and post-acute sequelae of COVID-19 (PASC)-like cytokine profile up to 245 days after vaccination may contribute to post-COVID vaccination syndrome in SARS-CoV-2-uninfected individuals

These findings suggest that the persistence of vaccine-derived S1 protein in CD16+ monocytes, and post-acute sequelae of COVID-19-like cytokine profile, may contribute to persistent post-COVID-19 vaccination syndrome.

A case series of 30 patients with newly diagnosed or relapsing glomerular diseases (immunoglobulin A nephropathy as the most common) after COVID vaccination

The most common glomerular disease after COVID-19 vaccination was immunoglobulin A nephropathy (IgAN). The absolute risk of glomerular diseases increased after the second or third COVID-19 mRNA vaccination.

The persistence of vaccine-derived S1 protein in CD16+ monocytes and post-acute sequelae of COVID-19 (PASC)-like cytokine profile up to 245 days after vaccination may contribute to post-COVID vaccination syndrome in SARS-CoV-2-uninfected individuals

These findings suggest that the persistence of vaccine-derived S1 protein in CD16+ monocytes, and post-acute sequelae of COVID-19-like cytokine profile, may contribute to persistent post-COVID-19 vaccination syndrome.

One year after mRNA COVID-19 immunization, the young people show elevated cytokine levels, suggesting ongoing stimulation of the immune system

The results showed that vaccination led to increased cytokine levels even one year after vaccination. Furthermore, the results indicated differences in cytokine levels based on gender and age.

A specific immunological profile, serological evidence of recent Epstein-Barr virus reactivation, and circulating SARS-CoV-2 S1 protein were found in individuals with post-COVID vaccination syndrome up to 700 days after vaccination

This study demonstrated immunological and other characteristics in individuals experiencing persistent symptoms following COVID-19 vaccination.

A Korean nationwide study with 558,017 participants found that COVID-vaccinated individuals had a higher incidence of Alzheimer’s disease and mild cognitive impairment

The findings showed an increased incidence of Alzheimer’s disease and its prodromal stage, mild cognitive impairment, in COVID-vaccinated individuals, particularly those receiving mRNA vaccines, within three months post-vaccination.

By blocking the MAPK and NF-κB signaling pathways, pomegranate peel extract reduces inflammation and alleviates symptoms in a rat model of irritable bowel syndrome

These findings underline the potential of PPE in the treatment of intestinal diseases.

Passive transfer of IgG from patients with long COVID induces mechanical and thermal sensitivity and impairs locomotor activity in mice

These findings demonstrate that transfer of IgG from long COVID patients to mice replicates disease symptoms, underscoring a causative and heterogeneous role of IgG in the pathogenesis of long COVID.
