    The management of thyroid disorders during pregnancy is one of the most frequently disputed problems in modern endocrinology. It is widely known that thyroid dysfunction may result in subfertility, and, if inadequately treated during pregnancy, may cause obstetrical complications and influence fetal development. The 2007 Endocrine Society Practice Guideline endorsed with the participation of the Latino America Thyroid Association, the American Thyroid Association, the Asia and Oceania Thyroid Association and the European Thyroid Association, greatly contributed towards uniformity of the management of thyroid disorders during pregnancy and postpartum. Despite the tremendous progress in knowledge on the mutual influence of pregnancy and thyroid in health and disease, there are still important areas of uncertainty. There have been at least a few important studies published in the last 3 years, which influenced the thyroidal care of the expecting mother. It should also be remembered that guidelines may not always be universally applied in all populations with different ethnical, socio-economical, nutritional (including iodine intake) background or exposed to different iodine prophylaxis models. The Task Force for development of guidelines for thyroid dysfunction management in pregnant women was established in 2008. The expert group has recognized the following tasks: development of the coherent model of the management of thyroid dysfunction in pregnant women, identification of the group of women at risk of thyroid dysfunction, who may require endocrine care in the preconception period, during pregnancy and postpartum – that is in other words, the development of Polish recommendations for targeted thyroid disorder case finding during pregnancy, and the development of Polish trimester-specific reference values of thyroid hormones. Comprehensive Polish guidelines developed by the Task Force are to systematize the management of the thyroid disorders in pregnant women in Poland.

Powszechnie wiadomo, 偶e dysfunkcja tarczycy mo偶e by膰 przyczyn膮 zaburze艅 p艂odno艣ci, a nieleczona prawid艂owo w czasie ci膮偶y zwi臋ksza ryzyko powik艂a艅 po艂o偶niczych oraz ma wp艂yw na rozw贸j p艂odu. Opublikowane w 2007 roku wytyczne Towarzystwa Endokrynologicznego (Endocrine Society), opracowane przy wsp贸艂udziale Towarzystwa Tyreologicznego Ameryki 艁aci艅skiej (LATS), Towarzystwa Tyreologicznego Azji i Oceanii (AOTA), Ameryka艅skiego Towarzystwa Tyreologicznego (ATA) oraz Europejskiego Towarzystwa Tyreologicznego (ETA), w du偶ym stopniu usystematyzowa艂y zasady post臋powania w chorobach tarczycy w czasie ci膮偶y i w okresie poporodowym. Pomimo ogromnego post臋pu wiedzy na temat wzajemnego wp艂ywu ci膮偶y i funkcji gruczo艂u tarczowego w zdrowiu i chorobie, jaki osi膮gni臋to w ci膮gu ostatnich kilkunastu lat, nadal pewne obszary wymagaj膮 dalszych bada艅. W ci膮gu 3 lat, kt贸re min臋艂y od publikacji wytycznych, przyby艂o danych, kt贸re wp艂yn臋艂y na niekt贸re zasady prowadzenia ci臋偶arnej z chorob膮 tarczycy. Wytyczne nie zawsze maj膮 charakter uniwersalny i nie mog膮 by膰 w prosty spos贸b transponowane na spo艂ecze艅stwa zr贸偶nicowane etnicznie i ekonomicznie, o odmiennych zwyczajach dietetycznych, w tym w spo偶yciu no艣nik贸w jodu, oraz stosuj膮ce odmienne modele profilaktyki jodowej. W 2008 roku powo艂ano Zesp贸艂 Ekspert贸w do spraw Opieki Tyreologicznej w Ci膮偶y. Za cele prac Zespo艂u przyj臋to: opracowanie modelu opieki nad ci臋偶arn膮 z zaburzeniami funkcji tarczycy, okre艣lenie grupy kobiet z ryzykiem zaburze艅 funkcji tarczycy wymagaj膮cych oceny tyreologicznej podczas planowania ci膮偶y, w trakcie jej trwania oraz w okresie poporodowym — czyli przygotowanie polskich wskaza艅 do bada艅 przesiewowych oraz ustalenie warto艣ci referencyjnych st臋偶e艅 hormon贸w tarczycy w poszczeg贸lnych trymestrach ci膮偶y. Opracowane przez Zesp贸艂 wytyczne systematyzuj膮 zasady opieki tyreologicznej nad kobiet膮 ci臋偶arn膮 w Polsce. (Endokrynol Pol 2011; 62 (4): 362–381

Abnormalities in dopamine signaling involved in the reward circuit may ensue excessive consumption of food, resulting in obesity and leading to neuropsychiatric disorders such as depression. This study sought to investigate the association of polymorphisms in the genes encoding DAT1/SLC6A3 and COMT with the intensity of depressive symptoms in obese subjects.Participants and methods: Prevalence and severity of depressive symptoms were assessed in a group of 364 obese patients using the Beck Depression Inventory (BDI) and the Hamilton Depression Rating Scale (HDRS). Genetic polymorphisms in DAT1 and COMT were evaluated in peripheral blood samples.Results: The results indicated an association between DAT1 alleles and depressive symptoms, as well as severity of obesity. Subjects homozygous for the nine-repeat allele scored higher in BDI (P=0.022) and HDRS (P=0.00001), suggesting higher intensity of depression in both sexes. This allele was also associated with the highest body mass index (BMI; P=0.001). Carriers of the Val158Met allele of COMT scored higher on both depression scales (BDI, P=0.0005; HRDS, P=0.002) and had the highest BMI values.Conclusion: Polymorphisms in the DAT1 and COMT genes are associated with a greater intensity of depressive symptoms in the obese population.Keywords: dopaminergic signaling, obesity, depressive symptoms, reward circuit, gene poly­morphis
