Thyroid nodules (TNs) are a common pathology. Their prevalence increases with age. Some of them are suspected of malignancy and qualified for surgery. Sometimes their malignant nature is detected incidentally after a surgical procedure. The aim of the study is to analyze clinical and histopathological characteristics of patients with incidental and nonincidental thyroid carcinoma (ITC vs. NITC). ⋯ There are no differences in gender, age or histopathological type of cancer in patients with ITC and NITC. Papillary TC is the predominant type in both groups. Incidence of TC in a solitary nodule is significantly higher in NITC than ITC. Solitary type of TC is an independent predictor of NITC. The prevalence of ITC is associated with multifocal type of TC.

Recent studies have revealed that vitamin D and its synthetic analogues have a protective effect on experimental ischemia/reperfusion (I/R) models in several organs, but little is known about its effect on the liver. The aim of this study was to evaluate the beneficial effects of vitamin D in a model of liver I/R in rats, focusing on Toll-like receptor (TLR) 4 signaling, which has been shown to be involved in I/R injury. ⋯ The vitamin D analogue paricalcitol attenuates hepatic I/R injury through down-regulation of the TLR4 signaling pathway and might be considered to be a potential nutritional therapeutic agent against I/R injury in the liver.

Due to the pathogenetic association between erectile disorders and cardiovascular diseases, cardiologists consult many patients with erectile dysfunction (ED). The aim of the study was to evaluate sexual function in patients with coronary heart disease (CHD) and the use of sexual knowledge in cardiology practice, both current use and that expected by patients. ⋯ The low frequency with which cardiologists initiate the topic of ED is in contrast to the expectations of patients with CHD. The majority of these patients regard good sexual maintenance as an important part of their life.

Increased urine neutrophil gelatinase-associated lipocalin (uNGAL) concentrations are associated with the early phase of kidney damage. Urine NGAL may increase due to production by neutrophils present in urine, particularly in patients with urinary tract infections. The aim of the study was to assess the relationship between sterile leukocyturia and uNGAL concentrations in patients with type 2 diabetes (DMt2) at early stages of diabetic kidney disease. ⋯ In patients with DMt2, the presence of sterile leukocyturia coexists with increased uNGAL and UNCR. Leukocyturia interferes with the relationship between UNCR and UACR or HbA1c.

Mammographic screening results in diagnosis of less advanced breast cancer (BC). A meta-analysis of randomized clinical trials confirmed that BC screening reduces mortality. In 2007, the National Breast Cancer Screening Program (NBCSP) was established in Poland with the crucial aim of reducing mortality from BC. The purpose of this study was to assess the impact of participation in the NBCSP on prognosis. ⋯ The study results revealed the beneficial impact of the NBCSP. Superior prognostic factors and favorable staging were observed in women who participated in the NBCSP.
