COVID-19 and long-term risk of incident laboratory-defined micronutrient deficiency in patients with type 2 diabetes: a multicenter propensity score–matched cohort study

Background COVID-19 has been linked to broad post-acute sequelae, but delayed micronutrient deficiency remains insufficiently characterized. Whether COVID-19 increases long-term risks of laboratory-defined vitamin D, magnesium, and vitamin B12 deficiencies among patients with type 2 diabetes mellitus is unclear. Method...

Long-term risk of incident dementia following documented COVID-19 among older adults with type 2 diabetes: a propensity score-matched cohort study

Background Type 2 diabetes mellitus (T2DM) is a well-established risk factor for dementia, and COVID-19 has been associated with persistent neurological and cognitive sequelae. However, whether this association extends beyond the early post-infection period among older adults with T2DM—a population with compounded vasc...

Long-term risk of incident autoimmune thyroid disease after COVID-19 in patients with type 2 diabetes: a multicenter propensity score–matched cohort study

Background Viral infections have been implicated in thyroid autoimmunity, and COVID-19 has emerged as a possible trigger. However, current evidence is mostly limited to case reports and short-term studies evaluating broad thyroid dysfunction rather than autoimmune-specific thyroid disease. This study aimed to evaluate...

COVID-19 and subsequent risk of coded diabetic retinopathy in patients with type 2 diabetes: a multicenter propensity score-matched cohort study

Background Evidence remains limited regarding whether coronavirus disease 2019 (COVID-19) is associated with the subsequent risk of EHR-recorded diabetic retinopathy (DR) during available follow-up in patients with type 2 diabetes mellitus (T2DM). We evaluated the risk of EHR-recorded DR and clinically relevant DR subt...

U-shaped pattern in the association between serum magnesium levels and long-term dementia risk after traumatic brain injury: a retrospective cohort study

Background In the general population, abnormal serum magnesium levels are associated with an increased risk of cognitive decline and dementia. However, whether this association extends to patients with traumatic brain injury (TBI), a population with distinct neurobiological vulnerabilities, remains unknown. Methods Usi...
