Quantifying the risk of spillover reduction programs for human health.

Reducing spillover of zoonotic pathogens is an appealing approach to preventing human disease and minimizing the risk of future epidemics and pandemics. Although the immediate human health benefit of reducing spillover is clear, over time, spillover reduction could lead to counterintuitive negative consequences for human health. Here, we use mathematical models and computer simulations to explore the conditions under which unanticipated consequences of spillover reduction can occur in systems where the severity of disease increases with age at infection.

Use of Analgesics and Sedatives in Nontraumatic Patients after Sudden Cardiac Arrest during the Peri-Resuscitation Period in the Emergency Department.

While cardiopulmonary resuscitation (CPR) may be life-saving for patients in cardiac arrest, it simultaneously puts them at risk for skeletal and soft tissue injuries. The prevalence of cardiovascular and thoracic wall injuries related to CPR varies significantly in the literature, from 21% to more than 78%. After restoration of circulation, ischemia-reperfusion brain injury ensues.

Reservoir displacement by an invasive rodent reduces Lassa virus zoonotic spillover risk.

The black rat (Rattus rattus) is a globally invasive species that has been widely introduced across Africa. Within its invasive range in West Africa, R. rattus may compete with the native rodent Mastomys natalensis, the primary reservoir host of Lassa virus, a zoonotic pathogen that kills thousands annually.

Predicting the fine-scale spatial distribution of zoonotic reservoirs using computer vision.

Zoonotic diseases threaten human health worldwide and are often associated with anthropogenic disturbance. Predicting how disturbance influences spillover risk is critical for effective disease intervention but difficult to achieve at fine spatial scales. Here, we develop a method that learns the spatial distribution of a reservoir species from aerial imagery.

Optimizing the delivery of self-disseminating vaccines in fluctuating wildlife populations.

Zoonotic pathogens spread by wildlife continue to spill into human populations and threaten human lives. A potential way to reduce this threat is by vaccinating wildlife species that harbor pathogens that are infectious to humans. Unfortunately, even in cases where vaccines can be distributed en masse as edible baits, achieving levels of vaccine coverage sufficient for pathogen elimination is rare.

Analgesic Use in Patients during Cardio-Pulmonary Resuscitation.

Introduction: Cardiopulmonary resuscitation-induced consciousness is a newly recognized phenomenon with an increasing incidence. A return of consciousness during cardiopulmonary resuscitation affects up to 0.9% of cases.

Reservoir population ecology, viral evolution and the risk of emerging infectious disease.

The ecology and life history of wild animals influences their potential to harbour infectious disease. This observation has motivated studies identifying empirical relationships between traits of wild animals and historical patterns of spillover and emergence into humans. Although these studies have identified compelling broad-scale patterns, they are generally agnostic with respect to underlying mechanisms.

The Impact of Reflection on Death on the Self-Esteem of Health Care Workers.

Background: The study was based on the Terror Management Theory. This theory assumes that self-preservation and awareness of imminent death create the potential to trigger fear. The "culture buffer" can protect people from fear, and it is composed of two factors: personal views on world issues and self-esteem.

Searching for the Optimal Method of Financing Hospital Emergency Departments-Comparison of Polish and Selected European Solutions.

Hospital emergency departments are units of the State Medical Rescue system in Poland, which was established to help people in a state of a health emergency. The aim of this study is to develop an optimal method of financing emergency departments in Poland. The study used Polish data from 2016-2019 on the financing of services at the Clinical Emergency Department of the University Clinical Center in Gdańsk.

Feasibility of Chest Wall and Diaphragm Proprioceptive Neuromuscular Facilitation (PNF) Techniques in Mechanically Ventilated Patients.

Unlabelled: Physical therapy is part of the treatment for patients admitted to ICU. Proprioceptive neuromuscular facilitation (PNF) is one of the physiotherapy concepts including manual techniques and verbal stimulation. The purpose of this paper is to examine the feasibility of PNF techniques in mechanically ventilated (MV) ICU patients.

Quantifying the effectiveness of betaherpesvirus-vectored transmissible vaccines.

Transmissible vaccines have the potential to revolutionize how zoonotic pathogens are controlled within wildlife reservoirs. A key challenge that must be overcome is identifying viral vectors that can rapidly spread immunity through a reservoir population. Because they are broadly distributed taxonomically, species specific, and stable to genetic manipulation, betaherpesviruses are leading candidates for use as transmissible vaccine vectors.

Suppressing evolution in genetically engineered systems through repeated supplementation.

Genetically engineered organisms are prone to evolve in response to the engineering. This evolution is often undesirable and can negatively affect the purpose of the engineering. Methods that maintain the stability of engineered genomes are therefore critical to the successful design and use of genetically engineered organisms.

Bridging the gap: Using reservoir ecology and human serosurveys to estimate Lassa virus spillover in West Africa.

Forecasting the risk of pathogen spillover from reservoir populations of wild or domestic animals is essential for the effective deployment of interventions such as wildlife vaccination or culling. Due to the sporadic nature of spillover events and limited availability of data, developing and validating robust, spatially explicit, predictions is challenging. Recent efforts have begun to make progress in this direction by capitalizing on machine learning methodologies.

Bayesian estimation of Lassa virus epidemiological parameters: Implications for spillover prevention using wildlife vaccination.

Lassa virus is a significant burden on human health throughout its endemic region in West Africa, with most human infections the result of spillover from the primary rodent reservoir of the virus, the natal multimammate mouse, M. natalensis. Here we develop a Bayesian methodology for estimating epidemiological parameters of Lassa virus within its rodent reservoir and for generating probabilistic predictions for the efficacy of rodent vaccination programs.

The Southern Ocean and its interaction with the Antarctic Ice Sheet.

The Southern Ocean exerts a major influence on the mass balance of the Antarctic Ice Sheet, either indirectly, by its influence on air temperatures and winds, or directly, mostly through its effects on ice shelves. How much melting the ocean causes depends on the temperature of the water, which in turn is controlled by the combination of the thermal structure of the surrounding ocean and local ocean circulation, which in turn is determined largely by winds and bathymetry. As climate warms and atmospheric circulation changes, there will be follow-on changes in the ocean circulation and temperature.

When to vaccinate a fluctuating wildlife population: Is timing everything?

Wildlife vaccination is an important tool for managing the burden of infectious disease in human populations, domesticated livestock and various iconic wildlife. Although substantial progress has been made in the field of vaccine designs for wildlife, there is a gap in our understanding of how to time wildlife vaccination, relative to host demography, to best protect a population.We use a mathematical model and computer simulations to assess the outcomes of vaccination campaigns that deploy vaccines once per annual population cycle.

Evolution and containment of transmissible recombinant vector vaccines.

Transmissible vaccines offer a revolutionary approach for controlling infectious disease and may provide one of the few feasible methods for eliminating pathogens from inaccessible wildlife populations. Current efforts to develop transmissible vaccines use recombinant vector technology whereby pathogen antigens are engineered to be expressed from innocuous infectious viral vectors. The resulting vaccines can transmit from host to host, amplifying the number of vaccine-protected individuals beyond those initially vaccinated directly through parenteral inoculation.

Transmissible vaccines in heterogeneous populations: Implications for vaccine design.

Transmissible vaccines may provide a promising solution for improving the control of infectious disease, particularly zoonotic pathogens with wildlife reservoirs. Although it is well known that heterogeneity in pathogen transmission impacts the spread of infectious disease, the effects of heterogeneity on vaccine transmission are largely unknown. Here we develop and analyze a mathematical model that quantifies the potential benefits of a transmissible vaccine in a population where transmission is heterogeneous between two subgroups.

A little goes a long way: Weak vaccine transmission facilitates oral vaccination campaigns against zoonotic pathogens.

Zoonotic pathogens such as Ebola and rabies pose a major health risk to humans. One proven approach to minimizing the impact of a pathogen relies on reducing its prevalence within animal reservoir populations using mass vaccination. However, two major challenges remain for vaccination programs that target free-ranging animal populations.

Selective PPARδ Modulators Improve Mitochondrial Function: Potential Treatment for Duchenne Muscular Dystrophy (DMD).

The X-ray structure of the previously reported PPARδ modulator bound to the ligand binding domain (LBD) revealed that the amide moiety in exists in the thermodynamically disfavored -amide orientation. Isosteric replacement of the -amide with five-membered heterocycles led to the identification of imidazole (MA-0204), a potent, selective PPARδ modulator with good pharmacokinetic properties. MA-0204 was tested in mice and in patient-derived muscle myoblasts (from Duchenne Muscular Dystrophy (DMD) patients); altered the expression of PPARδ target genes and improved fatty acid oxidation, which supports the therapeutic hypothesis for the study of MA-0204 in DMD patients.

Nurses' Knowledge and Barriers Regarding Pain Management.

Purpose: The purpose of this study was to identify Polish nurses' experiences and perceptions about the barriers to postoperative pain management in older adults.

Design: The study was conducted using a dedicated questionnaire.

Methods: Eleven hospitals participated in this study.

Controlling epidemics with transmissible vaccines.

As the density of human and domestic animal populations increases, the threat of localized epidemics and global pandemics grows. Although effective vaccines have been developed for a number of threatening pathogens, manufacturing and disseminating vaccines in the face of a rapidly spreading epidemic or pandemic remains a formidable challenge. One potentially powerful solution to this problem is the use of transmissible vaccines.

Treatment of patients with acute coronary syndrome: Recommendations for medical emergency teams: Focus on antiplatelet therapies. Updated experts' standpoint.

A group of Polish experts in cardiology and emergency medicine, encouraged by the European Society of Cardiology (ESC) guidelines, have recently published common recommendations for medical emergency teams regarding the pre-hospital management of patients with acute coronary syndrome. Due to the recent publication of the 2017 ESC guidelines for the management of acute myocardial infarction in patients presenting with ST-segment elevation and 2017 focused update on dual antiplatelet therapy in coronary artery disease the current panel of experts decided to update the previous standpoint. Moreover, new data coming from studies presented after the previous document was issued were also taken into consideration.

Evaluating the promise of recombinant transmissible vaccines.

Transmissible vaccines have the potential to revolutionize infectious disease control by reducing the vaccination effort required to protect a population against a disease. Recent efforts to develop transmissible vaccines focus on recombinant transmissible vaccine designs (RTVs) because they pose reduced risk if intra-host evolution causes the vaccine to revert to its vector form. However, the shared antigenicity of the vaccine and vector may confer vaccine-immunity to hosts infected with the vector, thwarting the ability of the vaccine to spread through the population.
