A Common Marmoset Model of Mother-Infant Intervention for Breastfeeding Disorders in the Presence of Paternal Inhibition and Maternal Neglect
0 Views •
2023
Here, we present a nonhuman primate model of mother-infant intervention for breastfeeding disorders in the presence of paternal inhibition and maternal neglect. The mate model video complements education to support primate and human caregivers with respect to infants with breastfeeding problems such as pain.

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT Intravenous (IV) fluid administration and peripheral IV catheters (PIVs) may be discontinued for a number of reasons. The most common reason for discontinuing IV fluids is that the patient has returned to normal body fluid volume (euvolemia) and is able to maintain adequate oral fluid intake or is being discharged from the hospital. In addition, the Centers for Disease Control Guidelines...

Source: David Guo, College of Engineering, Technology, and Aeronautics (CETA), Southern New Hampshire University (SNHU), Manchester, New Hampshire An airfoil is a 2-dimensional wing section that represents critical wing performance characteristics. The pressure distribution and lift coefficient are important parameters that characterize the behavior of airfoils. The pressure distribution is directly related to the lift generated by airfoils. A Clark Y-14 airfoil, which is used in this...
FAQs
Right parietal injury can disrupt a broader attention network that allocates importance to spatial information. As a result, representations from one side of the environment receive less attentional weighting than competing representations from the other side. This imbalance helps explain why omissions can appear across different activities rather than being limited to a single visual target or task.
The central problem is disrupted spatial attention rather than primary loss of vision or motor strength. A person may therefore fail to respond to information on one side because it is not being adequately selected or weighted, not because the stimulus is necessarily unseen or movement is impossible. This distinction guides assessment and supports more targeted rehabilitation planning.
Uneven weighting means that competing parts of the environment do not receive equal priority during attention. The resulting behavior can include systematic omissions when a person scans, describes, or reproduces visual material. Because the same attentional imbalance may appear in several formats, clinicians can compare task performance to identify a broader spatial pattern rather than relying on one isolated error.
Clinicians commonly examine performance with line bisection, target cancellation, object description, and drawing. Together, these tasks provide different ways to observe spatial omissions and the allocation of attention. Comparing the resulting patterns can help reveal characteristic neglect-related behavior, supporting clinical interpretation, lesion localization, and later evaluation of whether spatial behavior changes with intervention.
Patterns across neglect assessments can contribute to lesion localization by linking characteristic spatial omissions with disruption of the right parietal region or broader attention networks. The same findings also help clinicians plan rehabilitation and establish a baseline for follow-up. Repeating relevant tasks over time allows outcome monitoring to focus on changes in spatial behavior rather than a single general impression.
These approaches are used in rehabilitation to address the uneven spatial behavior associated with neglect. Visual-scanning training aims to support more effective exploration of the environment, while prism-based approaches aim to rebalance spatial behavior. Their relevance extends beyond diagnosis because clinicians can monitor task performance before and after intervention to evaluate whether attentional and behavioral patterns change.
