The association of self-esteem variability with diurnal cortisol patterns in a sample of adult workers.

This study explored the relationships between self-esteem level and self-esteem variability at work with parameters of diurnal cortisol rhythm, using intensive longitudinal data collected during two consecutive working days from N = 166 workers. Participants self-reported measures of sex, height, weight, self-esteem, neuroticism, and negative events at T0. Then, they answered a single item of self-esteem 4 times per day.

Climate-related drivers of nutrient inputs and food web structure in shallow Arctic lake ecosystems.

In order to predict the effects of climate change on polar ecosystems, disentangling mechanisms of nutrient transfer in food webs is crucial. We investigated sources of nutrients in tundra lakes, tracing their transfer through the food web and relating the observed patterns to runoff, snow coverage, and the presence of migratory geese in lake catchments. C and N content (elemental and isotopic) of several food web components including Lepidurus arcticus (Notostraca, at the top of the lake food webs) in 18 shallow Arctic lakes was compared.

Retrospective analysis of safety of ultrasound-guided percutaneous liver biopsy in the 21st century.

Background: Ultrasound-guided percutaneous liver biopsy is a standard procedure, but it might be burdened with serious adverse events, mainly hemorrhagic. Literature lacks recent studies taking into account new ultrasound machines, more sensitive to tiny vessels and the evolution of the bioptic technique, including ultrasound guidance in all instances. Hence, the primary aim of this study was to evaluate complication rates of ultrasound-guided percutaneous liver biopsy in a recent population.

Role of elastosonography in the differentiation between benign and malignant neoformations of the breast and possibility of reducing the number of FNACS for tissue characterization.

Introduction: Background The aim of the paper is related to our experience defining the diagnostic accuracy of breast elastosonog-raphy.

Objective: The aim of our study is therefore to define the diagnostic accuracy of breast elastosonography in the differential diagnosis of nodular breast neoformations to improve the characterization of the solid lesion and reduce the number of needle aspiration unnecessary for benign formations.

Material And Methods: A total of 88 patients were enrolled, who came to the Department with an ultrasound diagnosis of a breast lesion.

Radiological Parameters Review for Choanal Atresia.

(1) Background: The study aims to identify which imaging parameters are necessary for a new correct surgical approach in the study of choanal atresia, and which anatomical findings are essential for correct planning of endoscopic treatment in choanal atresia. (2) Methods: In this retrospective study, 19 patients with choanal atresia had high-resolution multiplanar imaging (14 cases aged ≤1 year and 5 cases aged 1 to 3 years) and 35 patients in the control group similarly distributed by age. Fourteen variables, the most relevant from a surgical point of view, were selected and measured.
