Selective advantage of redirected helping in a viscous population.

When a brood fails, the failed parent can help a neighbor rear its offspring. This behavior is known as redirected helping and occurs in various species. The advantage of redirected helping may seem obvious, provided the individual whose brood fails helps a related neighbor: the helper at least gains indirect fitness by redirecting its parental effort.

Evolution of delayed dispersal with group size effect and population dynamics.

Individuals delay natal dispersal for many reasons. There may be no place to disperse to; immediate dispersal or reproduction may be too costly; immediate dispersal may mean that the individual and their relatives miss the benefits of group living. Understanding the factors that lead to the evolution of delayed dispersal is important because delayed dispersal sets the stage for complex social groups and social behavior.

Shear Wave Elastography, a New Tool for Diaphragmatic Qualitative Assessment: A Translational Study.

Prolonged mechanical ventilation is often associated with either a decrease (known atrophy) or an increase (supposed injury) in diaphragmatic thickness. Shear wave elastography is a noninvasive technique that measures shear modulus, a surrogate of tissue stiffness and mechanical properties. To describe changes in shear modulus (SM) during the ICU stay and the relationship with alterations in muscle thickness.

Effect of a prospective audit with intervention and feedback on Clostridioides difficile infection management.

Background Clostridioides difficile infections are associated with morbidity and mortality in several countries. Their increasing incidence and frequent recurrence make them an urgent public health threat. The lack of adherence to international treatment guidelines for Clostridioides difficile infections is a proven mortality risk factor.

Correction to: Real-time shear wave ultrasound elastography: a new tool for the evaluation of diaphragm and limb muscle stiffness in critically ill patients.

In the publication of this article [1], there was an error in the Family Name of one of the authors. This has now been updated in the original article.

Real-time shear wave ultrasound elastography: a new tool for the evaluation of diaphragm and limb muscle stiffness in critically ill patients.

Background: Muscle weakness following critical illness is the consequence of loss of muscle mass and alteration of muscle quality. It is associated with long-term disability. Ultrasonography is a reliable tool to quantify muscle mass, but studies that evaluate muscle quality at the critically ill bedside are lacking.
