The aim of this study is to delineate laboratory diagnostic strategies for subclinical hypothyroidism in patients who are clinically symptomatic but may have a normal thyroid profile. Tri — iodothyronine (T3), thyroxine (T4), thyroid stimulating hormone (TSH) and anti thyroid peroxidase antibodies (anti-TPO) were estimated on fasting blood samples from 99 patients using electrochemiluminescence methods on ELECSYS 1010 (Roche). 74% of study subjects had elevated anti-TPO levels.61% patients had subclinical hypothyroidism. 45 of the 61 subclinical hypothyroid patients had elevated anti-TPO levels (73%). This is an important finding suggesting an autoimmune etiology for subclinical thyroid dysfunction with a higher risk of developing overt hypothyroidism.  相似文献

The global growth in postgraduate (PG) study since the mid-1990s has been attributed to the expansion in Masters by Coursework participation (Bekhradnia, B. (2005). Postgraduate education in the UK: Trends and challenges higher education policy institute. Paper presented at a conference The future of postgraduate education supporting the students of today and tomorrow, London, 17 March). However, unlike at undergraduate level, research into understanding PG growth has been under-researched. This paper aims to contribute to the knowledge gap by identifying and comparing the growth in PG study in Australia, Canada, the USA and the UK. It explores the possible drivers behind the growth and concludes by highlighting potential challenges facing the future of PG study across the sector.  相似文献
