Effects of low-carbohydrate diet therapy in overweight subject with autoimmune thyroiditis: possible synergism with ChREBP Feb 2016 https://www.dovepress.com/effects-of-low-carbohydrate-diet-therapy-in-overweight-subject-with-au-peer-reviewed-article-DDDT Conclusion -A dietary plan based on the reduction of carbohydrate content and free of goitrogenic foods leads not only to a decrease in body weight, but also determines a decrease in fat mass and a significant drop of sentinel autoantibodies in Hashimoto’s thyroiditis. So, future studies could shed new light on the probable synergism between ChREBP-LXR, environmental contaminants, regulation of lipogenesis, and autoantibody production. Do not underestimate the value of the levels of anti-microsomal Abs, still not considered relevant in screening for autoimmune thyroiditis, the dietary regime described in this study could be implemented for the treatment of patients with autoimmune thyroid because of the possibility to reduce the inflammation state in general and of the thyroid gland in particular, and consequently of the levels of autoantibodies, information this surely important in the assessment of these patients and for the prediction of the course of the disease.
Selenium and Thyroid Disease: From Pathophysiology to Treatment. Jan 2017.https://www.ncbi.nlm.nih.gov/pubmed/28255299
Conclusion. Maintaining a physiological concentration of selenium is a prerequisite to prevent thyroid disease and preserve overall health. Supplementation with the organic form is more effective, and patients with autoimmune thyroiditis seem to have benefits in immunological mechanisms. Selenium supplementation proved to be clinically beneficial in patients with mild to moderate Graves' orbitopathy.

Current Thyroid Cancer Trends in the United States published Feb 20 2014 in the Journal of American Medical Association
According to the MJA* - News in Brief
US researchers have called for action to reduce overdiagnosis and overtreatment of thyroid cancer after an analysis revealed the incidence of the cancer had nearly tripled from 4.9 to 14.3 per 100 000 people over 3 decades. The analysis, published in JAMA Otolaryngology–Head & Neck Surgery, looked at secular trends in patients diagnosed with thyroid cancer from 1975 to 2009. The researchers wrote that almost the entire increase in cancer diagnosis was attributable to papillary thyroid cancer, from 3.4 to 12.5 cases per 100 000 population over the time period. In women, the absolute increase in thyroid cancer diagnosis was almost four times that of men. The mortality rate of 0.5 deaths per 100 000 cases had been stable. The researchers wrote that the US seemed to have an “epidemic of diagnosis” of thyroid cancer. “A simple way that physicians could begin today [to approach this problem] would be to openly share with patients the uncertainty surrounding small thyroid cancers — explaining that many will never grow and cause harm to a patient — but it is not possible to know with certainty which ones fall into that category”, they wrote.

January 2014 - Paradigm shifts in thyroid hormone replacement therapies for hypothyroidism http://www.nature.com/nrendo/journal/vaop/ncurrent/full/nrendo.2013.258.html#access
Abstract : Impaired psychological well-being, depression or anxiety are observed in 5–10% of hypothyroid patients receiving levothyroxine, despite normal TSH levels. Such complaints might hypothetically be related to increased free T4 and decreased free T3 serum concentrations, which result in the abnormally low free T4:free T3 ratios observed in 30% of patients on levothyroxine. Evidence is mounting that levothyroxine monotherapy cannot assure a euthyroid state in all tissues simultaneously, and that normal serum TSH levels in patients receiving levothyroxine reflect pituitary euthyroidism alone. Levothyroxine plus liothyronine combination therapy is gaining in popularity; although the evidence suggests it is generally not superior to levothyroxine monotherapy, in some of the 14 published trials this combination was definitely preferred by patients and associated with improved metabolic profiles. Disappointing results with combination therapy could be related to use of inappropriate levothyroxine and liothyronine doses, resulting in abnormal serum free T4:free T3 ratios. Alternatively, its potential benefit might be confined to patients with specific genetic polymorphisms in thyroid hormone transporters and deiodinases that affect the intracellular levels of T3 available for binding to T3 receptors. Levothyroxine monotherapy remains the standard treatment for hypothyroidism. However, in selected patients, new guidelines suggest that experimental combination therapy might be considered.
Nov 2013 - Vitamin d deficiency and its association with thyroid disease http://www.ncbi.nlm.nih.gov/pubmed/24533019
OBJECTIVES: Vitamin D deficiency is a global health problem, its role as an immune modulator has been recently emphasized. The evidence is increasingly pointing towards vitamin D significant role in reducing the incidence of autoimmune diseases. However, at this time the research on its role in autoimmune and thyroid disease is not conclusive. We aimed to examine the relationship between hypothyroidism and vitamin D deficiency and to clarify the relation between serum calcium levels with hypothyroid disease
CONCLUSION: Our results indicated that patients with hypothyroidism suffered from hypovitaminosis D with hypocalcaemia that is significantly associated with the degree and severity of the hypothyroidism. That encourages the advisability of vit D supplementation and recommends the screening for Vitamin D deficiency and serum calcium levels for all hypothyroid patients.

CONCLUSION:DTE therapy did not result in a significant improvement in quality of life; however, DTE caused modest weight loss and nearly half (48.6%) of the study patients expressed preference for DTE over L-T₄. DTE therapy may be relevant for some hypothyroid patients.
Aust Prescriber 2011;34:12-5 -Thyroid function tests Robin H Mortimer, Professor, Department of Endocrinology, Royal Brisbane and Women's Hospital, and the University of Queensland, Brisbane http://www.australianprescriber.com/magazine/34/1/12/5
Thyroid disorders can be difficult to detect clinically, but thyroid function tests can assist in making a diagnosis. Measuring thyroid stimulating hormone is the first step. If it is abnormal, free thyroxine should be measured. A raised concentration of thyroid stimulating hormone with a low concentration of free thyroxine suggests hypothyroidism. A low concentration of thyroid stimulating hormone with a high concentration of free thyroxine suggests hyperthyroidism. Measuring thyroid autoantibodies may help establish the cause of the dysfunction. Different assays can give different results, and tests of thyroid function may be affected by drugs and intercurrent illness.
Dec 2011 - The Link between Thyroid Function and Depression http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3246784/
Abstract : The relation between thyroid function and depression has long been recognized. Patients with thyroid disorders are more prone to develop depressive symptoms and conversely depression may be accompanied by various subtle thyroid abnormalities. Traditionally, the most commonly documented abnormalities are elevated T4 levels, low T3, elevated rT3, a blunted TSH response to TRH, positive antithyroid antibodies, and elevated CSF TRH concentrations. In addition, thyroid hormone supplements appear to accelerate and enhance the clinical response to antidepressant drugs. However, the mechanisms underlying the interaction between thyroid function and depression remain to be further clarified. Recently, advances in biochemical, genetic, and neuroimaging fields have provided new insights into the thyroid-depression relationship.
