2) Recent studies have shown that viral infections that are commonly associated with viral myocarditis and other autoimmune diseases. Viruses like coxsackievirus B3 (CVB3) that cause myocarditis frequently target mitochondria to boost viral replication.
3) They disrupt mitochondria, leading to the release of damaged mitochondria and virus-containing mitochondrial extracellular vesicles (EVs). EVs contain a mix of viral and mitochondrial self-antigens. When these EVs activate pattern recognition receptors like TLR4 ...
The study examined the relationship between T-cell telomere length (TL) parameters and T-cell counts in 40 patients ... frontiersin.org/journals/immunโฆ
2) ...hospitalized with severe COVID-19.
On admission to the intensive care unit, the mean T-cell count was 1.03 x109/L. The mean TL was 3.88 kilobases and 45.3% of telomeres were shorter than 3 kb.
T-cell count decreased with age and was higher in females than males.
3) Using regression analysis adjusting for age and sex:
- T-cell count decreased as the proportion of T-cell telomeres shorter than 3 kb increased.
- T-cell count increased as mean TL increased, though this result was marginally significant.
2) This study analyzed brain MRI findings in 102 pediatric patients infected with Omicron who were admitted to PICUs with neurological complications. The average age was 5.8 years and most patients were male. Common symptoms included fever, convulsions and altered consciousness.
3) MRI was performed 1-12 days after symptom onset in 93 patients. Abnormal neuroimaging findings were seen in 74% of cases. The most common finding was acute necrotizing encephalopathy seen in 48% of cases with abnormal MRI. This involved lesions in the thalamus, brainstem ...
2) The study analyzed the viral load and its relationship to various factors for over 16,800 COVID-19 patient samples in Mexico. Viral load was quantified using the ฮCt method.
3) Viral load was highest in the first few days after symptom onset and decreased over time. Differences in viral load between variants were only seen in the first 2 days.
