Observational Study
Prospective evaluation of vascular changes in acute respiratory infections in children with cystic fibrosis.
Acute exacerbations and chronic inflammation are risk factors for cardiovascular disease (CVD) in cystic fibrosis (CF) patients. The aim of this study was to investigate the effects of acute exacerbation therapy on arterial stiffness in children with CF. ⋯ The decrease of arterial stiffness (Aix) with acute exacerbation treatment in children with CF has been demonstrated. This result shows that systemic inflammation in CF may cause an increase in arterial stiffness and recurrent exacerbations may increase the risk of CVD.

Quorum sensing (QS) is a chemical communication process that bacteria use to regulate virulence. Inhibition of QS (antiQS) overcomes the pathogenicity of bacteria. Silver nanoparticles (AgNPs) have been used as antimicrobials against pathogens, but have not been used against QS-mediated bacterial infection. Also, studies have been carried out on the inhibitory effects of propolis based structures on pathogen growth, but no studies have been found on their potential use as QS inhibitor. The present study aims to investigate the synthesis and characterization of silver nanoparticles (AgNPs) reduced with propolis extract (P–AgNPs) and evaluation of their antimicrobial and, for the first time, antiQS activity. ⋯ Our results suggest that P–AgNPs may be potentially used to inhibit bacterial physiological processes due to the signal molecules regulates important collective behavior of bacteria. The development of such nontoxic biomaterials may have great potential to evaluate for the new medicinal substance that inhibits the pathogenic biofilms.

In the literature, there is a paucity of data about the effects of fibromyalgia syndrome (FMS) on myocardial function and electrophysiological properties of atrium and ventricles. In this study, we investigated cardiac functions and noninvasive predictors of arrhythmias in patients with FMS. ⋯ FMS is found to be associated with significant cardiac electrical alterations that may indicate the increased risk of atrial and ventricular arrhythmias in this group of patients.

Comparative Study
Comparing the complications of laparoscopically performed simple, radical and donor nephrectomy.
The aim of this study was to compare the complications of laparoscopic simple, radical and donor nephrectomies performed in a single center. ⋯ In this study, the frequency of complications in LRN procedures was found to be higher than the LSN and LDN procedures. Patients with LRN may have more adverse health conditions before the operation. Considering the results of this study, variables such as patient and hospital characteristics, surgeon experience and skills should be evaluated in future studies. In addition, it is important to determine the frequency of complications using a standardized classification in order to enable correct interpretation of results.

To emphasize the role of cochlear implantation (CI) in the auditory rehabilitation of patients with otosclerosis (OS) and share our surgical experiences on this rare group of patients. ⋯ Our experience on CI in patients with OS revealed that the implantation was a relatively safe procedure and had satisfactory impact on audiological performances.
