A single measurement of any biomarker may not reflect its full biological meaning. The kinetics of fibrosis-linked microRNAs and their relationship with extracellular matrix (ECM) fibrosis in dilated cardiomyopathy (DCM) have not been explored. ⋯ Regardless of ECM fibrosis status or duration of the disease, 12-month patterns of circulating microRNAs are similar in DCM. Correlations between microRNAs, measured at 3 and 12 months, are lower than expected. In this study, regardless of the time point, circulating microRNAs were not able to differentiate between DCM patients with versus without fibrosis.

Autologous saphenous vein (SV) and internal mammary artery (IMA) are used as bypass conduits during coronary artery bypass graft surgery. Vasospasm of the arterial and venous grafts may constitute a significant clinical problem. Pretreatment with a vasodilator drug of the graft ex vivo or intraluminal injection before implantation may be used for spasm prophylaxis. This in vitro study was designed to assess the vasoactive effects and time-dependent changes of botulinum toxin A (BTX-A) and papaverine pretreatment on vasospasm of human SV and IMA grafts. Also, histomorphology of the vessels was assessed. ⋯ This study demonstrates that in human SV and IMA grafts, pretreatment with both BTX-A and papaverine are safe and have a potent inhibitory effect depending on the vessel and vasoconstrictor agent. The long-lasting vasodilatory effect of BTX-A on vascular smooth muscle may provide promising results in the prevention of venous and arterial graft spasm.

The aim of our study was to evaluate testicular growth and risk of atrophy at different lengths of time from the 2SLF-SO in boys with intra-abdominal cryptorchidism. ⋯ Two-stage laparoscopic Fowler-Stevens operation proved to be an effective procedure for the treatment of intra-abdominal testicles. The undescended testis had a chance to grow and to equalize with the healthy testis after this procedure. The incidence of testicular atrophy was low.

The primary prevention is intended to prevent the development of diseases, secondary prevention aims to limit disease progression, and tertiary prevention involves reducing disease-associated symptoms. The purpose of this study was to assess the use of selected forms of secondary prevention by patients diagnosed with perennial allergic rhinitis. Moreover, this paper presents the ways in which the adopted organizational solutions could be utilized as part of coordinated healthcare to benefit patients with perennial allergies. ⋯ The proportion of patients diagnosed with a dust-mite allergy, who undertook preventive measures against perennial allergic rhinitis, was relatively low. Building, maintaining, and continual strengthening the doctors' relationship with chronic allergy patients may shift the nature of healthcare services more towards preventive measures, for the implementation of which the patient will be co-responsible under the coordinated healthcare system.

Lung cancer is one of the most common causes of cancer-related mortality in the 21st century. Statins as inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A reductase not only reduce the cholesterol levels in the blood and decrease the risk of cardiovascular disease but may also play an important role in the prevention and treatment of lung cancer. ⋯ Statins reduce angiogenesis in tumors by down-regulation of pro-angiogenic factors, such as vascular endothelial growth factor. In this review, the feasibility and efficacy of statins in the prevention and treatment of lung cancer are discussed.
