Article Synopsis
  • Pylorospasm, a condition that can resemble pyloric stenosis, is rare in neonates and has limited treatment options, often discussed in case reports.
  • A 2-month-old girl with ongoing vomiting and failure-to-thrive was diagnosed with pylorospasm after negative pyloric ultrasounds, and concurrent hypothyroidism was also identified.
  • Treatment involved intravenous (IV) atropine, which resolved her vomiting, followed by a successful transition to oral atropine, leading to improved weight gain and feeding.

Objectives: Many interventions in bronchiolitis are low-value or poorly studied. Inpatient bronchiolitis management is multidisciplinary, with varying degrees of registered nurse (RN) and respiratory therapist (RT) autonomy. Understanding the perceived benefit of interventions for frontline health care personnel may facilitate deimplementation efforts.

Article Synopsis
  • - The study aimed to assess the stability of intracortical microelectrodes implanted in the motor and somatosensory cortex of a person with a spinal cord injury, focusing on how recording quality changes over time and the ability to evoke sensations through stimulation.
  • - Findings showed that while both types of electrodes (platinum in the motor cortex and sputtered iridium oxide film (SIROF) in the somatosensory cortex) exhibited decreased signal quality over time, SIROF electrodes were better at continuously recording high-quality signals.
  • - The detection thresholds for sensations evoked by stimulation decreased significantly over the course of the study, suggesting that ICMS can effectively provide sensory feedback for an extended period without adversely affecting recording

Article Synopsis
  • Microstimulation of the somatosensory cortex can create artificial tactile sensations and may be used in brain-computer interfaces (BCIs) to help restore sensory function after injury or illness.
  • Researchers tested how different stimulation settings, like amplitude and frequency, affected these sensations in two human subjects with spinal cord injuries.
  • They discovered that while higher amplitude and longer stimulation increased perceived intensity, frequency effects varied, leading to either stronger or weaker sensations depending on the electrode used, which could inform better BCI development.

Article Synopsis
  • Prosthetic arms can be controlled by brain-computer interfaces (BCIs), allowing people with tetraplegia to perform functional movements, but they often lack effective feedback during grasping.
  • To enhance feedback, researchers used a bidirectional BCI that records brain activity and provides tactile sensations through microstimulation of the somatosensory cortex, improving the user's experience.
  • With this technology, a participant significantly improved their performance with a robotic limb, cutting their task completion time in half from 20.9 seconds to 10.2 seconds by reducing time spent on grasping objects.

Children with autism spectrum disorder have been found to have lower levels of vitamin D than their peers. Our case report supports the hypothesis that vitamin D may be an effective treatment for developmental delay in autism. In addition, we review the literature surrounding vitamin D deficiency as a potential cause of autism spectrum disorder and the role that vitamin D may play in treatment.
