The development of the behavioral effects of amphetamine was assessed in kittens of 1-53 days of age. Amphetamine-induced increases in locomotion occurred when animals were beyond 35 days of age. Stereotypic behavior was induced at all ages tested but the predominant type of stereotypy was age-related. From 1 to 14 days amphetamine induced licking. Pendular head movements occurred when animals were under 35 days. At 14 days of age darting, a response consisting of rapid pacing and turning began to occur. Tracking, a series of horizontal and vertical head movements also began to occur after 14 days. The adult response of vertical and horizontal head movements became most prominent after 35 days.

Measured resting energy expenditure and predicted resting energy expenditure based on ASPEN critical care guidelines for nutrition support: An agreement study.
JPEN J Parenter Enteral Nutr

Department of Dietitian Services, Abbotsford Regional Hospital, Abbotsford, British Columbia, Canada.
Background: Predictive equations often inaccurately estimate energy needs in critically ill patients. This study evaluated the level of agreement between resting energy expenditure using 12 and 25 kcal/kg as recommended by the 2021 American Society for Parenteral and Enteral Nutrition critical care guidelines for nutrition support and energy expenditure measured by indirect calorimetry in patients in the intensive care unit.
Methods: An agreement study was conducted on mechanically ventilated adults who had a documented measured energy expenditure within 10 days of intensive care unit admission.
Survey on the practice of skin-to-skin contact in Spanish neonatal units during the first days of life. Influence of the presence of umbilical catheters.

Introduction: Skin-to-skin contact (SSC) offers multiple benefits in preterm newborns (PTNBs), but its implementation can be delayed due to the presence of some devices such as umbilical venous catheters (UVCs). Our objective was to evaluate the practice of SSC in PTNBs in Spanish neonatal units and how the type of catheter affects its initiation.
Methods: We distributed a survey through the Sociedad Española de Neonatología to Spanish neonatal units, analyzing the timing of SSC initiation and the influence on this practice of the types of devices being used.
Atrial fibrillation development in the heart failure population from nationwide British linked electronic health records.
ESC Heart Fail
March 2025
Institute of Health Informatics Research, University College London, London, UK.
Aims: Atrial fibrillation (AF) is a frequent comorbidity in heart failure (HF). We analysed factors associated with new-onset atrial fibrillation in patients with heart failure using linked real-world UK data from primary and secondary care, along with findings from genome-wide association studies.
Methods And Results: Among 163 174 participants with a diagnosis of HF (January 1998 to May 2016) from Clinical Practice Research Datalink (CPRD) and Hospital Episodes Statistics (HES), 111 595 participants had no previous history of AF (mean age 76.
Acute severe hepatitis in children following extrahepatic infection in South Korea: etiology, clinical course, and outcomes.

Department of Pediatrics, Chonnam National University Children's Hospital, Gwangju, Korea.
Background: Acute hepatitis can occur in association with systemic diseases outside the liver. Acute severe hepatitis with markedly elevated transaminase levels following extrahepatic infection has been reported in children. However, research on this condition remains limited.

Department of Pediatrics, Yokohama City University.
Background: Recently, the role of a rapid increase in serum osmolality in the inhibition of postnatal ductal closure has garnered attention. This study evaluated the efficacy of high-humidity care in preventing the onset of patent ductus arteriosus (PDA) in extremely premature infants.
Methods And Results: The high-humidity group (HHG) comprised 28 infants (24to 27weeks gestational age) recruited prospectively within 6 h after birth between July 2019 and September 2021; these infants were cared for in 90% humidity for the first 72 h of life.
