Introduction: Activities of daily living (ADL) refer to the ability to perform the essential self-care activities that are necessary to have a life without dependency. Development of chronic diseases such as heart disease, as age progresses, can affect ADL. Facilitating the return of patients to the ADL and determining the level of care is one of the responsibilities of nurses. Therefore, using Barthel and Katz indexes, this study aimed to assess ADL dependency after discharge from cardiac care unit (CCU). Methods: In this descriptive cross-sectional study, 180 patients were selected by the available sampling method. Data were analyzed before and after admission to the CCU using SPSS software version 13. Results: The mean score of the Barthel and Katz indexes, before admission to the CCU, was 92.96 and 5.37, respectively, which changed to 82.85 and 4.57 post-cardiac care unit (P-CCU). Accordingly, ADL dependency increased after discharge from CCU. Conclusion: After discharge from the CCU (in P-CCU), patients do not return to the same level of activities before hospitalization, and the functional status and ability of patients to perform daily activities decrease.

Introduction: Hypothyroidism is a common endocrine disorder that, occurs in 2% to 5% of pregnancies. During pregnancy, the body's demand for thyroid hormones increases, which affects the growth of the fetus. In case of inadequate and defective production of thyroid hormones, adverse effects on the development of the fetus will appear. Lack of symptoms of hypothyroidism during pregnancy causes late diagnosis, resulting in a lack of timely treatment and impaired fetal development. The purpose of this review is to investigate the effects of mothers' hypothyroidism on children. Methods: This systematic review study was performed by searching the Google Scholar, PubMed, and Science Direct databases for the period between 2018 and 2008 by including the keywords for hypothyroidism, thyroid hormones, growth in the uterus. A number of papers related to the use of the Cochran seven-step model were obtained and analyzed for the final analysis. Results: Thyroid hormones play a vital role in fetal development for ectopic life, through direct and indirect mechanisms that, act on the development of the fetus. Thyroid hormones help in the synthesis of surfactant and lung evolution, stimulation of secretion of catecholamine, increased beta-adrenergic receptors of the lung and stimulation: the activity of sodium and potassium pumps in the alveolar cell surface, the effect on the transmission of brain neurotransmitters and growth hormone, and nervous function. Conclusions: Thyroid hormones play a key role in fetal development. Therefore, in women with hypothyroidism, especially when not treated, it affects the development of the fetus and increases the incidence of complications in neonates. So early diagnosis of hypothyroidism and adequate and timely treatment during pregnancy is cornerstone in preventing impaired growth and development of the fetus and the occurrence of defects in childhood.
