Initial evaluation of thyroid dysfunction - Are simultaneous TSH and fT4 tests necessary? [PDF]

, 2018
ObjectiveGuidelines for thyroid function evaluation recommend testing TSH first, then assessing fT4 only if TSH is out of the reference range (two-step), but many clinicians initially request both TSH and fT4 (one-step).

TSH enhancement of FT4 to FT3 conversion is age dependent [PDF]

European Journal of Endocrinology, 2016
ObjectiveWe previously reported increasing free T3 (FT3) to free T4 (FT4) ratios as thyroid-stimulating hormone (TSH) increases within the normal range in children. It is not known if this phenomenon is age-related among humans, as previously reported in rats.

Association between thyroid dysfunction and cognitive impairment in type 2 diabetes mellitus: A cross-sectional study. [PDF]

J Diabetes Investig
Hypothyroidism is an independent risk factor for cognitive impairment in T2DM patients, with a progressive risk increase associated with higher TSH levels. These findings underscore the importance of integrating thyroid function evaluation into the cognitive assessment and management strategy for this patient population.
