Long-term Thyroid Outcomes After COVID-19 Vaccination: A Cohort Study of 2,333,496 Patients from the TriNetX Network.

Context: Reports on long-term thyroid dysfunction following COVID-19 vaccination are limited. Understanding the risk of subacute thyroiditis, hyperthyroidism, and hypothyroidism in vaccinated individuals is crucial for post-vaccination monitoring.

Objective: This study evaluated the risk of thyroid dysfunction in COVID-19 vaccinated individuals compared to unvaccinated individuals using a large cohort.

Limited ability to extend the digits of the human hand independently with extensor digitorum.

While the human hand has an extraordinary capacity to manipulate objects, movement of its digits is usually not completely independent. These limits have been documented for extrinsic flexor muscles, although hand skills also require selectivity for extension movements. Hence, we measured the degree of independent control of the major extrinsic extensor (extensor digitorum, ED).
