Sex-specific response of intramuscular fat to diet-induced obesity in rats.

Metabolic abnormalities associated with excess adiposity in obesity contribute to many noncommunicable diseases, including sarcopenic obesity. Sarcopenic obesity is the loss of muscle mass coupled with excess fat mass and fatty infiltrations in muscle tissue called myosteatosis. A diet-induced obesity model was developed to study fat infiltration in muscle tissue.

Phasing of de novo mutations using a scaled-up multiple amplicon long-read sequencing approach.

De novo mutations (DNMs) play an important role in severe genetic disorders that reduce fitness. To better understand their role in disease, it is important to determine the parent-of-origin and timing of mutational events that give rise to these mutations, especially in sex-specific developmental disorders such as male infertility. However, currently available short-read sequencing approaches are not ideally suited for phasing, as this requires long continuous DNA strands that span both the DNM and one or more informative single-nucleotide polymorphisms.

Focused assessment with sonography for trauma in predicting early surgical intervention in hemodynamically unstable children with blunt abdominal trauma.

Objectives: The predictive accuracy and clinical role of the focused assessment with sonography for trauma (FAST) exam in pediatric blunt abdominal trauma are uncertain. This study investigates the performance of the emergency department (ED) FAST exam to predict early surgical intervention and subsequent free fluid (FF) in pediatric trauma patients.

Methods: Pediatric level 1 trauma patients ages 0 to 15 years with blunt torso trauma at a single trauma center were retrospectively reviewed.

Knowledge acquisition and retention following Saving Children's Lives course for healthcare providers in Botswana: a longitudinal cohort study.

Objectives: Millions of children die every year from serious childhood illnesses. Most deaths are avertable with access to quality care. Saving Children's Lives (SCL) includes an abbreviated high-intensity training (SCL-aHIT) for providers who treat serious childhood illnesses.

Multiple micronutrient supplementation transiently ameliorates environmental enteropathy in Malawian children aged 12-35 months in a randomized controlled clinical trial.

Background: Environmental enteropathy (EE) is subclinical, diffuse villous atrophy characterized by T cell infiltration of the small intestinal mucosa associated with nutrient malabsorption and stunting. EE is assessed by the lactulose:mannitol (L:M) test, whereby nonmetabolized sugars are ingested and quantified in the urine. Multiple micronutrient (MN) deficiency morphologically mimics EE, and ω-3 (n-3) polyunsaturated fatty acids reduce mucosal inflammation in Crohn disease.
