Alcohol and cannabinoid binges and daily exposure to nicotine in adolescent/young adult rats induce sex-dependent long-term appetitive instrumental learning impairment.

Adolescence is a critical developmental period, concerning anatomical, neurochemical and behavioral changes. Moreover, adolescents are more sensitive to the long-term deleterious effects of drug abuse. Binge-like consumption of alcohol and marijuana, along with tobacco smoking, is a dangerous pattern often observed in adolescents during weekends.

Evaluating the use of anti-scatter grids in adult knee radiography.

Introduction: Anti-scatter grids efficiently reduce scatter radiation from reaching the imaging receptor, enhancing image quality; however, the patient radiation dose increases in the process. There is disagreement regarding the thickness thresholds for which anti-scatter grids are beneficial. This study aims to establish a thickness threshold for the use of anti-scatter grids to optimise adult knee radiography.

Fifteen-minute consultation: Imaging in paediatric major trauma.

With trauma being a leading cause of death for children, identifying all sustained injuries remains a priority for clinicians, and imaging is a key diagnostic tool to ensure that is achieved. However, children have a greater risk of detrimental effects of ionising radiation than adults. Clinicians therefore have to balance limiting their patients' radiation exposure to 'as low as reasonably achievable' with the need for diagnostic accuracy.

Impact on hand hygiene compliance following migration to a new hospital with improved resources and the sequential introduction of World Health Organization recommendations.

Background: One commonly cited reason for inadequate hand hygiene (HH) in health care facilities is lack of handwashing sinks and alcohol hand rub (AHR).

Methods: Using the World Health Organization (WHO) direct observation method, we studied HH compliance after migration from an old hospital having 1 HH station (sink and AHR) per 6 beds to a new institution with 1 per 0.85 beds.
