In the last five years, the American public health emergency preparedness and response system has been tested by two significant threats, H1N1 and Ebola. While neither proved as dangerous as initially feared, these viruses highlighted on-going issues with collaborations in the field of public health and health care. Strengths were identified within the network, but also challenges that must be resolved before the U.S. faces a major pandemic. Employing interview data from public health emergency response practitioners and documentary evidence from the H1N1 and Ebola responses, this qualitative analysis uses the grounded theory approach to identify key areas for collaborative improvement. The grounded theory developed calls for a stronger policy framework at the federal level to facilitate more collaboration between U.S. agencies and facilitate more collaboration at the state and local level.

The overdose epidemic in the United States is evolving, with a rise in stimulant (cocaine and/or methamphetamine)-only and opioid and stimulant-involved overdose deaths for reasons that remain unclear. We conducted interviews and group model building workshops in Massachusetts and South Dakota. Building on these data and extant research, we identified six dynamic hypotheses, explaining changes in stimulant-involved overdose trends, visualized using causal loop diagrams.

Influenza accounts for 30% of the total morbidity and mortality in the European Union. However, the specific burden in different European countries is largely unknown, and more research is needed to ascertain the reality of this disease. In this retrospective study, we analyzed the burdens of hospitalization, intensive care unit (ICU) admission and in-hospital mortality in Spain over five seasons (2015-2020) via publicly available Minimum Basic Datasets (MDBS).

In this work, we investigate the dynamics of a discrete-time prey-predator model considering a prey reproductive response as a function of the predation risk, with the prey population growth factor governed by two parameters. The system can evolve toward scenarios of mutual or only of predators extinction, or species coexistence. We analytically show all different types of equilibrium points depending on the ranges of growth parameters.
