Relational stability is a major motif of the intertwined feedback loops of #thyroid #homeostasis. The integrated systemic roles and interdependent homeostatically regulated equilibrium of TSH, FT4 and #deiodinase​s maintains appropriate FT3 concentrations.

Our eBook on #hypothyroidism has been published. The new cybernetic theory presented here summarises our scientific work of more than 20 years and lays the foundation for improved diagnosis and therapy of #thyroid disorders.

The book is available in EPUB and PDF formats.

Eine #Ketoazidose ist eine gefürchtete Komplikation eines #Diabetes mellitus. Weniger bekannt ist, dass auch andere endokrine Erkrankungen zu einer Ketoazidose führen können. In unserem neuesten Paper stellen wir eine besondere Ursache vor.

#Thyroid hormones play a pivotal role in #thermoregulation and the attunement to hot and cold #climate​s. Recent research found global patterns of variants in the UCP1 and UCP3 genes and #SPINA-GD (step-up #deiodinase activity), suggesting integrated adaptation.

Interestingly, both subclinical #hypothyroidism and #thyrotoxicosis predict #MACE. The free thyroxine (FT4) concentration is more associated with the HR for cardiovascular events than thyrotropin (TSH) levels. Our observations yield an integrated model including psychosocial and somatic mechanisms.

#Thyroid hormones profoundly impact the #cardiovascular system. They act at all levels, ranging from the tier of ion currents over cellular processes to the macroscopic levels of myocardial tissue and even the whole organism.

The #cardiovascular system is sensitive to #thyroid hormones. Even mild deviations of the free #thyroxine concentration from a (probably individual) optimum confer a significantly increased risk for #MACE (major adverse cardiovascular events).

Medical treatment of #hyperthyroidism, i.e. #thyrotoxicosis due to overproduction of #thyroid hormone, remains a challenge. We developed a new dosage methodology based on model predictive control (MPC), which is faster and more stable than the usual trial-and-error approach. https://doi.org/10.1016/j.ifacol.2025.03.041

Diabetes mellitus is common in hidradenitis suppurativa (acne inversa). Affected persons are faced with low insulin sensitivity (#SPINA-GR) and a lack of dynamic compensation via pancreatic beta-cell function (#SPINA-GBeta), resulting in a reduced disposition index (#SPINA-DI).

Multiple studies have proven the impact of #endocrine #disruptor​s, e.g. #phthalates and #parabens, on #thyroid #homeostasis. It was unknown, however, that these effects depend on whether or not the included persons are fasting.

Neben maschineller Probaganda könnte auch der negative #Flynn-Effekt eine Rolle spielen, eine Intelligenzabnahme durch endokrine #Disruptor​en.

About 10% of hypothyroid patients have reduced quality of life despite normal TSH concentration under therapy with levothyroxine (L-T4). A new randomised, double-blind trial demonstrated better QoL under L-T4 + L-T3 compared to L-T4 alone.

#Metformin is a useful antidiabetic substance, but also an endocrine disruptor. A recent study shows that it reduces the set point of #thyroid homeostasis, but this effect is mitigated by #vitamin_D deficiency.
