Urban Air Pollution Associated with the Incidence of Autoimmune Thyroid Diseases.

Background: Endocrine disrupting air pollutants such as sulphur dioxide (SO), carbon monoxide (CO), nitrogen dioxide (NO), fine particle matter (PM), and ozone (O) can affect thyroid gland function on the level of synthesis, metabolism, and the action of its hormones.

Objective: The aim of this study was to establish whether increased air pollution could contribute to an increased incidence of autoimmune thyroid diseases (AITD).

Methods: A retrospective analysis was conducted of the medical records of 82000 patients at the University Clinical Centre in Tuzla, Bosnia and Herzegovina.

The Epidemiological Characteristics of Autoimmune Thyroiditis in the Tuzla Canton in the Period from 2015 to 2020.

Background: Bosnia and Herzegovina (B&H) is one of the countries of Southeast Europe with the lack of data about chronic autoimmune thyroid diseases (CAITD) epidemiology.

Objective: This research aimed to assess incidence of CAITD in the Tuzla Canton of B&H during a 6-year period (2015-2020).

Methods: We retrospectively evaluated 82,000 hospital records of inpatients and outpatients with possible thyroid symptoms residing in Tuzla Canton of B&H (total of 445,028 inhabitants).

Nonthyroidal illness syndrome in off-pump coronary artery bypass surger.

Objective: It is well known that coronary artery bypass grafting (CABG) is often the cause of non-thyroidal illness syndrome (NTIS). Non-thyroidal illness syndrome (NTIS) is a state characterized by low levels of tri-iodo-thyronine (T3) and high levels of reverse T3 (rT3), with normal or low levels of thyroxin (T4) and normal, low-normal, or low levels of thyroid-stimulating hormone (TSH). Today, there are two main techniques of CABG: CABG with the use of cardiopulmonary bypass (on-pump coronary artery bypass - ONCAB) and CABG without the use of cardiopulmonary bypass (off-pump coronary artery bypass OPCAB), or 'beating-heart surgery.

Direct coronary stenting in reducing radiation and radiocontrast consumption.

Introduction: Coronary stenting is the primary means of coronary revascularization. There are two basic techniques of stent implantation: stenting with balloon predilatation of stenosis and stenting without predilatation (direct stenting). Limiting the time that a fluoroscope is activated and by appropriately managing the intensity of the applied radiation, the operator limits radiation in the environment, and this saves the exposure to the patient and all personnel in the room.
