Objective: To examine the longitudinal trajectory of daytime dysfunction (DD) and its relationship with fatigue by depression status in university students.
Participants: 243 students completed online surveys from September- December 2016.
Methods: Surveys were conducted at three time points over a semester period: the beginning of the semester, the end of mid-term and the end of the semester.
Results: Results indicated that the DD significantly increased in all students over the semester. Students with depression showed a higher initial level of DD and faster rate of change compared to those without depression. A faster rate of change of DD predicted a higher level of end-semester fatigue.
Conclusions: Depression is related to a higher initial level of DD and its faster rate change which in turn, predicted end-semester fatigue, identifying one of the possible pathways through which depression impacts the functioning and health of affected students.

Purpose: Patient-controlled analgesia (PCA) has been considered for managing cancer pain; however, limited research has been conducted on optimizing continuous infusion rates with PCA. This study aimed to evaluate the efficacy and safety of a method that optimizes background infusion (BI) alongside PCA for titrating intravenous (IV) morphine in managing cancer-related pain.
Methods: Forty-four patients with solid tumors who could not manage pain with oral or transdermal opioid analgesics were randomly assigned in a 1:1 ratio to receive IV morphine through PCA or the conventional method.

Cell collectives, like other motile entities, generate and use forces to move forward. Here, we ask whether environmental configurations alter this proportional force-speed relationship, since aligned extracellular matrix fibers are known to cause directed migration. We show that aligned fibers serve as active conduits for spatial propagation of cellular mechanotransduction through matrix exoskeleton, leading to efficient directed collective cell migration.

Caenorhabditis elegans proliferates poorly in the presence of abundant Actinobacteria from its natural ecology, but it is unknown why. Here, we show how perturbed levels of hydrogen sulfide modulate the growth rate of both C. elegans and Actinobacteria.

The time needed for the evolution of mating cues that distinguish species, such as species-specific songs or plumage coloration in birds, has received little attention. Aiming to gain some understanding of the timing of the evolutionary process we here present models of how mating cues evolve in populations split into subpopulations between which there may (parapatry) or may not (allopatry) be migration. Mating cues can be either neutral or directly selected.

Background: Olfactory deficits are predictive of cognitive decline and dementia. Previous studies have linked brain magnetic resonance imaging markers of neurodegeneration to olfactory deficits in aging; however, these studies analyzed cross-sectional data for markers, olfaction, or both. Furthermore, potential cerebrovascular contributions to understanding why olfactory deficits predict dementia remain unexplored.
