Combined impact of fear and Allee effect in predator-prey interaction models on their growth.

We considered predator-prey models which incorporated both an Allee effect and a new fear factor effect together, and where the predator predated the prey with a Holling type I functional response. We started off with a two-dimensional model where we found possible equilibria and examined their stabilities. By using the predator mortality rate as the bifurcation parameter, the model exhibited Hopf-bifurcation for the coexistence equilibrium.

Diagnosis and Treatment of Infections in the Burn Patient.

Infection is very common in burn patients because they lose the primary barrier from microorganism invasion, the skin. While there are attempts to prevent infections, topical antimicrobials and systemic prophylaxis tend to lead to more resistant organisms. After the initial resuscitation, the most common cause of death is from sepsis and multiple organ dysfunction syndrome.

The Hand Accumulation aNd Dexterity FUnctional Limits-Shriners (HANDFULS): A New Clinically Feasible Measure of Hand Volume and In-Hand Manipulation for Children.

Importance: Having a problem-specific hand function test that can be administered easily with children is important for consistency in measuring and monitoring outcomes.

Objective: To introduce basic testing procedures for Hand Accumulation aNd Dexterity FUnctional Limits-Shriner (HANDFULS), a clinically feasible hand outcome measure for two common hand problems, in-hand manipulation and palmar workspace volume; examine its face validity and test-retest reliability; and provide reference values for children and adolescents with typically developed, noninjured hands as a foundation for further study.

Design: Prospective cohort study.

Burn Injury Severity in Adults: Proposed Definitions Based on the National Burn Research Dataset.

Previous iterations of burn severity (mild, moderate, and severe) were not data-driven and were outdated. Clustering analyses have gained popularity for identifying homogenous subgroups from heterogeneous medical conditions, such as asthma, sepsis, and lung disease. There is no consensus in burn literature regarding what constitutes massive burns.
