Quantification Of The Negative Impact Of Sedation And Inotropic Support On Achieving Early Mobility In Burn Patients In Icu: A Single Center Observational Study, Lauren Bright, Lisa Van Der Lee, Dana Hince, Fiona M. Wood, Dale W. Edgar

IHR Papers and Journal Articles

Introduction: Early rehabilitation for burns survivors in the intensive care unit (ICU) is arguably more challenging than the general population. Early achievement of functional verticality milestones (FVMs) has the potential to ameliorate the detrimental effects of bed rest and immobility observed in ICU patients and reduce healthcare costs. However, the time to achieving FVMs after burn injury is influenced by factors such as sedation practices, cardiovascular stability, mechanical ventilation, acute skin reconstruction and length of stay (LOS) during the acute intensive care period.

Objectives/Aims: The aims of this study were to identify the association between early achievement of FVMs and …


Situationism, Capacities And Culpability, Adam Piovarchy Jan 2021

Situationism, Capacities And Culpability, Adam Piovarchy

IHR Papers and Journal Articles

The situationist experiments demonstrate that most people’s behaviour is influenced by environmental factors much more than we expect, and that ordinary people can be led to behave very immorally. A number of philosophers have investigated whether these experiments demonstrate that subjects’ responsibility-relevant capacities are impeded. This paper considers how, in practice, we can assess when agents have a reduced capacity to avoid wrongdoing. It critiques some previously offered strategies including appeals to the reasonable person standard, appeals to counterfactuals and understandability of behaviour, and appeals to base rates of wrongdoing. It then proposes we should think a certain factor impeded …

Using black soldier fly (BSF, Hermetia illucens) larvae as a novel protein source substituting fishmeal (FM) in animal feeds is globally gaining momentum. BSF can be reared on agro-industrial residues. However, incorporating BSF larval meal (BSFLM) into finisher pig diets has received inadequate attention. This study evaluated the effects of replacing dietary FM with BSFLM on growth, carcass traits and meat quality of finisher pigs. A control diet (including FM: 0% BSFLM) was compared with four dietary levels of replacement of FM with BSFLM at 25, 50, 75 or 100%. Forty hybrid pigs (crossbreeds of purebred Large White and Landrace) …

The riverine tsetse fly Glossina fuscipes fuscipes is a major vector of trypanosome pathogens causing African trypanosomiasis. This fly species uses a combination of olfactory and visual cues to locate its hosts. Previously, traps and targets baited with visual cues have been used in vector control, but the development of olfactory-based tools has been challenging. Recently, repellents have shown promise as olfactory-based tools in tsetse vector control. Here, we evaluated a three-component blend comprising 6-methyl-5-hepten-2-one, acetophenone and geranyl acetone (blend K), previously identified as a repellent for savannah tsetse flies in zebra skin odor, on G. f. fuscipes populations. Using …

In order to determine the threat that plant-parasitic nematodes pose to crop production, it is essential to establish an accurate estimation of their presence. The extraction efficiency from soil, therefore, is a critical step in establishing disease pressures presented by nematodes or the conditions of soil health. To achieve high nematode extraction efficiency, various methods and modifications have been developed over time (Oostenbrink, 1954; Seinhorst, 1956; Harrison & Green, 1976; Viaene et al., 2021) with variations being introduced locally, depending on the availability or access to certain materials. The simple extraction method was conceived and introduced by Baermann (1917), with …

The increasing demand for animal protein in sub-Saharan Africa has led to insects being considered an alternative protein source for food and feed. In Uganda, chicken mash, containing fish meal as the protein source is commonly used to rear crickets. However, fishmeal is an expensive protein source that is also human food. This study therefore aimed at establishing an alternative preferred (consumed in the highest quantity) plant leaf diet for raising the Modicogryllus conspersus cricket, and the most suitable temperature for hatchability and egg development. The effect of (a) three diets (cassava leaves + cocoyam leaves + milk weed leaves; …

The need for easily biodegradable and less toxic chemicals in drug development and pest control continues to fuel the exploration and discovery of new natural molecules. Like certain plants, some insects can also respond rapidly to microbial infections by producing a plethora of immune-induced molecules that include antibacterial and antifungal peptides/polypeptides (AMPs), among other structurally diverse small molecules. The recent recognition that new natural product-derived scaffolds are urgently needed to tackle life-threatening pathogenic infections has been prompted by the health threats posed by multidrug resistance. Although many researchers have concentrated on the discovery of AMPs, surprisingly, edible insect-produced AMPs/small molecules …

Sea level rise has increased the frequency of tidal flooding even without accompanying precipitation in many coastal areas worldwide. As the tide rises, inundates the landscape, and then recedes, it can transport organic and inorganic matter between terrestrial systems and adjacent aquatic environments. However, the chemical and biological effects of tidal flooding on urban estuarine systems remain poorly constrained. Here, we provide the first extensive quantification of floodwater nutrient concentrations during a tidal flooding event and estimate the nitrogen (N) loading to the Lafayette River, an urban tidal sub-tributary of the lower Chesapeake Bay (USA).
