Article Synopsis
- Sarcopenia and undernutrition impact clinical outcomes in hemodialysis patients, but their combined effects were not well studied before this research.
- The study analyzed 450 hemodialysis outpatients and found that 15.3% had both sarcopenia and undernutrition, correlating with a significantly lower survival rate and increased mortality risk.
- While the combined presence of sarcopenia and undernutrition increased the risk of death, it did not show a significant link to cardiovascular events, highlighting the need for targeted interventions in this population.
Backgrounds: Color Doppler ultrasonography (CDU) has not yet been established as a method to investigate the pathogenesis of thyrotoxicosis.
Objectives: Our first objective was to determine whether the measurement of peak systolic blood-flow velocity in the superior thyroid artery (STV) and thyroid tissue blood flow (TBF) using CDU could differentiate Graves' disease (GD) from painless thyroiditis (PT). The second objective was to examine the factors mediating increased blood flow to the thyroid gland in GD.
Background: We previously reported that multiple thyroid cysts may be a cause of hypothyroidism in patients with a relatively high iodine intake and we termed it polycystic thyroid disease (PCTD). The aim of this study was to investigate the prevalence of PCTD in patients who visited our thyroid center. We hypothesized that patients with PCTD are not rare in a region with a high iodine intake.

Here we present six patients from a region with relatively high iodine intake in whom multiple cysts of the thyroid were associated with hypothyroidism or the development of hypothyroidism.
Summary: All patients were women and ranged in age from 49 to 71.
