Smoking during pregnancy may impair thyroid function of mom and fetus
January 13, 2009Chevy Chase, MD-Cigarette smoking during pregnancy is associated with potentially harmful changes in both maternal and fetal thyroid function, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).
"We studied the influence of cigarette smoking on thyroid function of two groups of women at different stages of pregnancy - one in the first trimester and the other in the third trimester," said Dr. Bijay Vaidya, Ph.D., of Peninsula Medical School at Royal Devon and Exeter Hospital in the United Kingdom, and coauthor of the study. "In both groups we found that smoking during pregnancy is associated with changes in the mothers' thyroid hormone levels."
Optimal maternal thyroid function during pregnancy is vital for a successful pregnancy outcome, said Dr. Vaidya. The adverse outcomes associated with thyroid dysfunction during pregnancy include increased risk of miscarriage, premature birth, low birth weight and impaired neuropsychological development of the baby.
Dr. Vaidya and his colleagues also measured thyroid hormone levels in the umbilical cord of babies born to smoking mothers and found that smoking-related changes in thyroid function extend to the fetus. Dr. Vaidya believes that impaired thyroid function in the fetus could have potentially harmful biological consequences.
The study also found that in mothers who stopped smoking during pregnancy their thyroid hormone levels were comparable to levels found in non-smokers, which suggests that changes in thyroid function are rapidly reversible.
There is currently no definitive explanation for how smoking affects thyroid function, but Dr. Vaidya suggests that smoking may influence thyroid hormone levels by affecting the enzyme which converts the active form of thyroid hormone to an inactive form.

Thyroid Function Current Events and Thyroid Function News RSSNew genetic link between cardiac arrhythmias and thyroid dysfunction identified
Genes previously known to be essential to the coordinated, rhythmic electrical activity of cardiac muscle -- a healthy heartbeat -- have now also been found to play a key role in thyroid hormone (TH) biosynthesis, according to Weill Cornell Medical College researchers.
Concern over inappropriate diagnosis and treatment of thyroid problems
More and more people are being inappropriately diagnosed and treated for underactivity of the thyroid gland (known as primary hypothyroidism), warn doctors in an editorial published on bmj.com today.
Pediatric obesity may alter thyroid function and structure
In addition to its strong associations with hypertension, cardiovascular disease, and diabetes, pediatric obesity may induce alterations in thyroid function and structure, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).
Thyrotropin levels associated with Alzheimer's disease risk in women
Women with low or high levels of the hormone thyrotropin, which affects thyroid gland function and thyroid hormone levels, appear to have a higher risk of developing Alzheimer's disease, according to a report in the July 28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Thyrotropin levels may be associated with coronary heart disease mortality in women
Women with increasing levels of thyrotropin within the normal range appear to have a higher risk of fatal coronary heart disease, according to a report in the April 28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Thyroid treatment no 'quick fix' for weight loss in children
Children treated for hypothyroidism aren't likely to drop pounds with treatment for the condition says a new study in the Journal of Pediatrics. The study is the first to examine the link between hypothyroidism treatment and weight loss in pediatric patients.
Cancer patients' fatigue - new research shows it may be due more to depression and poor physical performance than physiological side effects
Fatigue - a common problem in patients who are recovering from leukaemia, lymphoma, myeloma and other haematological cancers - is associated with depression and reduced physical performance and not, as previously suggested, with anaemia, a flagging immune system or other physiological conditions. That is the conclusion of a German research team, reported today (Monday 19 July), in Annals of Oncology[1]. Cancer related fatigue - defined as an unusual and persistent sense of tiredness that can occur during or after treatment, may affect physical and mental ability and is not relieved by rest - is the most common and distressing problem for cancer patients after treatment. For many patients it
Poor prognosis for depression linked to an autoimmune thyroid condition?
Whether depression is linked to having an under-active thyroid gland has been debated for many years. Research published in BMC Psychiatry this week suggests that some patients with depression may be suffering from a subtle autoimmune thyroid condition, which could hinder their recovery. The study also suggests that physicians could use indicators of thyroid function to predict patients' responsiveness to antidepressants. As inpatients with depression often undergo routine thyroid tests, the data that physicians would need to create such a prediction are likely to be available to them already. Researchers from Greece studied 30 patients suffering from major depression, and 60 healthy people
To Benefit From Mushrooms
Mushrooms (of course, those grown in an ecologically safe area) accumulate many microelements good for human and animal health, in particular, selenium. The natural cycle of selenium was studied by a team from the Vernadsky Institute of Geochemistry and Analytical Chemistry in Moscow. The scientific expedition worked in the eastern part of the Meshchera (at the meeting point of the Moscow, Ryazan, and Vladimir areas). Scientists found selenium in many natural objects (soil, grass, leafs, elk`s excrements, mosquito larvae, and tissues of brown frog), however, its highest levels were observed in mushrooms. A concentration reached milligrams per

Thyroid Guardian of Health by Philip G. Young M.D. (Author) THYROID GUARDIAN OF HEALTH examines the impact inadequate thyroid function has on individuals. It starts with an introduction, the fact that hypothyroidism is frequently missed. A brief history of medicine's understanding of hypothyroidism is then given. This history is followed by various environmental factors that are increasing the incidence of hypothyroidism with its accompanying problems. Frequent clinical presentations of hypothyroidism are then given. The control of the thyroid hormone by the body is next described. The blood tests used for diagnosis of hypothyroidism are discussed along with the reasons the majority of hypothyroid patients are being missed when just the blood tests now in vogue are used. Next the interrelationship with the adrenal hormones,... |

Thyroid Hormones: Functions, Related Diseases and Uses by Francis S. Kuehn (Editor), Mauris P. Lozada (Editor) The thyroid is one of the largest endocrine glands in the body. The thyroid controls how quickly the body burns energy, makes proteins, and how sensitive the body should be to other hormones. It participates in these processes by producing thyroid hormones, principally thyroxine and triiodothyronine. These hormones regulate the rate of metabolism and affect the growth and rate of function of many other systems in the body. The thyroid also produces the hormone calcitonin, which plays a role in calcium homeostasis. As discussed in this book, both excess and deficiency of thyroxine can cause disorders. Thyrotoxicosis or hyperthyroidism, a cause of Graves Disease, is caused by an excess of circulating free thyroxine, free triiodothyronine, or both. Hypothyroidism is the case where there is a... |
