Percutaneous electrical nerve field stimulation improves comorbidities in children with cyclic vomiting syndrome.

Introduction: Children with cyclic vomiting syndrome (CVS) frequently suffer from disabling abdominal pain and comorbidities that impair quality of life. A noninvasive, auricular percutaneous electrical nerve field stimulation (PENFS) device is shown to be effective for abdominal pain in children with disorders of gut-brain interaction. We aimed to determine the effects of PENFS on pain, common comorbidities, and quality of life in pediatric CVS.

Rhinocerebral Mucormycosis Associated With Anterior Skull Base Actinomyces Osteomyelitis in a Pediatric Patient With Type 1 Diabetes.

Rhino-orbital-cerebral mucormycosis (ROCM) is a fulminant, often fatal, angioinvasive fungal infection commonly transmitted through inhalation of fungal spores and traumatic inoculation. While the literature has documented rare cases of infection in immunocompetent patients, the vast majority of case fatalities are noted in immunosuppressed populations. Common predisposing factors to infection include immunosuppressive therapies, hematologic malignancies, and most notably, uncontrolled diabetes.

Reimagining the Introductory Math Curriculum for Life Sciences Students.

Calculus is typically one of the first college courses encountered by science, technology, engineering, and mathematics (STEM) majors. Calculus often presents major challenges affecting STEM student persistence, particularly for students from groups historically underrepresented in STEM. For life sciences majors, calculus courses may not offer content that is relevant to biological systems or connect with students' interests in biology.

Autonomous cage-side system for remote training of non-human primates.

Background: Training non-human primates (NHPs) for translational medical experimentation is an essential yet time consuming process. To increase training efficiency, some training systems have been designed for NHPs to use at their home cages. Several autonomous cage-side tablet-based systems have been proposed, but none of these systems allow for remote monitoring and task modification while also being wireless, low-cost, light weight, and portable.

Acute Blockade of PACAP-Dependent Activity in the Ventromedial Nucleus of the Hypothalamus Disrupts Leptin-Induced Behavioral and Molecular Changes in Rats.

Leptin signaling pathways, stemming primarily from the hypothalamus, are necessary for maintaining normal energy homeostasis and body weight. In both rodents and humans, dysregulation of leptin signaling leads to morbid obesity and diabetes. Since leptin resistance is considered a primary factor underlying obesity, understanding the regulation of leptin signaling could lead to therapeutic tools and provide insights into the causality of obesity.

Cognitive pharmacy services at a pediatric nephrology and hypertension clinic.

Purpose: Pediatric patients require special attention from pediatric pharmacists. This is particularly true for pediatric patients with chronic kidney disease (CKD) as the number of their medications and the complexity of their treatment increase with disease progression. However, there is paucity of information describing pediatric cognitive pharmacy services in this setting.

Nonlinear and nonplanar dynamics of suspended nanotube and nanowire resonators.

Previous works on suspended carbon nanotube and nanowire resonators assume a priori that they oscillate in a single plane. We explore the nonlinear dynamics of such resonators and demonstrate that they can suddenly transition from a planar motion to a whirling, "jump rope" like motion. We identify nondimensional gate voltage, resonator geometry, quality factor, and flexural and axial elastic stiffnesses for which such motions can arise.
