Body image distortion: validation of a new scale for children and adolescents.

Background: A possible definition of body image is the picture that an individual has of her/his own body, irrespective of how her/his body actually is. Body image is a competence that develops in children similar to many other skills. The aim of this study was to validate a new rapid 20-items questionnaire to study the body image distortion in children and adolescents: the Strange Sensations Questionnaire (SSQ).

Prolonged preservation by hypothermic machine perfusion facilitates logistics in liver transplantation: A European observational cohort study.

A short period (1-2 h) of hypothermic oxygenated machine perfusion (HOPE) after static cold storage is safe and reduces ischemia-reperfusion injury-related complications after liver transplantation. Machine perfusion time is occasionally prolonged for logistical reasons, but it is unknown if prolonged HOPE is safe and compromises outcomes. We conducted a multicenter, observational cohort study of patients transplanted with a liver preserved by prolonged (≥4 h) HOPE.

Bioactive self-etching sealant on newly erupted molars: A split-mouth clinical trial.

Objectives: This randomized clinical trial compares retention, survival rate, and evolution of caries of newly erupted permanent molars sealed with bioactive self-etching sealants with pre-reacted glass ionomer (S-PRG).

Methods: A split-mouth clinical trial was conducted with 56 permanent second molars in stages 2 and 3 of crown eruption; ICDAS (International Caries Detection and Assessment System) was between 0 and 2. The molars were randomized and blinded in relation to the side (right or left) that would receive the sealants; the conventional resin sealant (FS), Fluroshield (Dentsply), or bioactive self-etch sealant (BS), BeautiSealant with S-PRG (Shofu).

Addition of 5% CO to Inspiratory Gas Prevents Lung Injury in an Experimental Model of Pulmonary Artery Ligation.

Unilateral ligation of the pulmonary artery may induce lung injury through multiple mechanisms, which might be dampened by inhaled CO. This study aims to characterize bilateral lung injury owing to unilateral ligation of the pulmonary artery in healthy swine undergoing controlled mechanical ventilation and its prevention by 5% CO inhalation and to investigate relevant pathophysiological mechanisms. Sixteen healthy pigs were allocated to surgical ligation of the left pulmonary artery (ligation group), seven to surgical ligation of the left pulmonary artery and inhalation of 5% CO (ligation + Fi 5%), and six to no intervention (no ligation).

Assessment of permeability of eroded dentin after the use of universal, self-etch, and conventional systems.

Dentin hypersensitivity is caused by increased dentinal permeability due to total or partial exposure of dentinal tubules, which in turn can be produced by alterations of dental structures or failure of restorative procedures. The purpose of this in vitro study was to evaluate the efficacy of the application of different kinds of adhesive systems to prevent dentin permeability before and after an erosive challenge. Fifty bovine dentin discs (6x1 mm) were prepared and the specimens were divided into 5 groups (n=10): (SB2) Single Bond 2, (SBU) Universal Single Bond, (CSB) Clearfil SE Bond, (SM) Scotchbond Multipurpose and (C) Control.
