A prospective registry of emergency department patients admitted with infection

<p>Abstract</p> <p>Background</p> <p>Patients with infections account for a significant proportion of Emergency Department (ED) workload, with many hospital patients admitted with severe sepsis initially investigated and resuscitated in the ED. The aim of this registry is to systematically collect quality observational clinical and microbiological data regarding emergency patients admitted with infection, in order to explore in detail the microbiological profile of these patients, and to provide the foundation for a significant programme of prospective observational studies and further clinical research.</p> <p>Methods/design</p> <p>ED patients admitted with infection will be identified through daily review of the computerised database of ED admissions, and clinical information such as site of infection, physiological status in the ED, and components of management abstracted from patients' charts. This information will be supplemented by further data regarding results of investigations, microbiological isolates, and length of stay (LOS) from hospital electronic databases. Outcome measures will be hospital and intensive care unit (ICU) LOS, and mortality endpoints derived from a national death registry.</p> <p>Discussion</p> <p>This database will provide substantial insights into the characteristics, microbiological profile, and outcomes of emergency patients admitted with infections. It will become the nidus for a programme of research into compliance with evidence-based guidelines, optimisation of empiric antimicrobial regimens, validation of clinical decision rules and identification of outcome determinants. The detailed observational data obtained will provide a solid baseline to inform the design of further controlled trials planned to optimise treatment and outcomes for emergency patients admitted with infections.</p

Hyperventilation syndrome: diagnosis and reassurance

This article provides an overview of hyperventilation syndrome (HVS). Hyperventilation is to breathe in excess of metabolic requirements; in the absence of an underlying organic cause, it is defined as HVS. Alternative terms used in literature are panic or anxiety attack, panic or anxiety disorder, dysfunctional breathing and breathing pattern disorder. This article explores HVS signs and symptoms beyond the familiar clinical signposts of tachypnoea, chest tightness, paraesthesia and anxiety. It will also discuss differential diagnoses and pre-hospital treatment of HVS, focusing on reassuring patients and assisting them in establishing a good respiratory pattern. Patients with HVS use a significant amount of hospital and emergency service resources, ideally placing paramedics to diagnose and treat HVS in the pre-hospital setting to avoid unnecessary and costly hospital admissions. Further research is needed to evaluate the pre-hospital prevalence and diagnostic accuracy of HVS, identify clear diagnostic criteria and design screening tools

Efeito da solarização e da adubação sobre artrópodes em solo cultivado com alface Solarization, organic and chemical fertilization combined effects on arthropods community in soil cultivated with lettuce

Avaliou-se o efeito da solarização e da adubação química e orgânica na comunidade de artrópodes de solo na cultura da alface, cv. Verônica. Foram conduzidos dois experimentos, em blocos ao acaso, um com solarização e o outro sem solarização, em casa de vegetação, ambos com cinco tratamentos: adubação orgânica; nitrogênio na forma amoniacal (NH4); adubação com NPK; adubação orgânica + NPK; testemunha (sem adubação). No experimento solarizado, o solo foi coberto durante 132 dias com plástico transparente. Os artrópodes foram coletados por meio de armadilhas tipo alçapão em três épocas (antes da implantação do experimento, após a solarização e após a colheita). Foram utilizados índices faunísticos e de diversidade em cada experimento, tratamento e épocas. Os principais grupos coletados foram: Collembola (82,8%), Acari (7,1%), Hymenoptera (6,1%) Coleoptera (1,3%) e outros (2,7%). A classe Collembola foi a mais abundante, mesmo na colheita, quando a subordem Acari aumentou substancialmente. As espécies de Collembola predominantes foram: Proisotoma tenella (Reuter) (34,3%); Seira atrolutea (Arlé) (29%); Folsomides centralis (Denis) (7,2%); Isotomurus sp. 161 (2,4%) e Sminthurides sp. 98 (1,6%). Observou-se que a diversidade e abundância da comunidade de artrópodes não foi influenciada pela solarização ou adubação.<br>To evaluate the effect of solarization, chemical and organic fertilization on soil arthropods community in lettuce, two blocks plots trials were carried out in Brasília, Brazil. One research was conducted with solarization and the other without solarization in a soil cultivated with lettuce, cv Veronica, under protected cultivation. Each trial consisted of five fertilization treatments: T1= organic fertilization; T2= amoniacal nitrogen (ammonium sulphate); T3= chemical fertilization; T4= organic and chemical fertilization; T5= control (without fertilization). In the solarized trial, the soil was covered for 132 days with transparent plastic. The arthropods were collected by pitfalls at three moments: 1) before solarization, 2) after solarization and 3) at harvest. Faunistic indexes were calculated in each trial, treatment and moments. The main collected groups were: Collembola (82.8%), Acari (7.1%), Hymenoptera (6.1%), Coleoptera (1.3%) and others (2.7%). Collembola class represented the largest proportion of the arthropods, even at harvest when the sub-order Acari substantially increased. The predominant species of Collembola were: Proisotoma tenella (Reuter) (34.3%); Seira atrolutea (Arlé) (29%); Folsomides centralis (Denis) (7.2%); Isotomurus sp.161 (2.4%) and Sminthurides sp. 98 (1.6%). Arthropods community was not affected by solarization or fertilization

Fungus-invertebrate interactions in Antarctica

In this chapter, we review the available literature on the associations of invertebrates and fungi across the different environments of Antarctica, the diversity underlined by this type of association and how the Antarctic fungal communities and their ecology can be affected by changes such as those in climate. We describe fungal interactions with individual groups of invertebrates, such as nematodes and insects, in both terrestrial and marine habitats. We conclude the chapter by exploring future possibilities for research regarding the impacts that environmental change and the introduction of non-native species may have in the region

'Now She's Just an Ordinary Baby': The Birth of IVF in the British Press.

The birth of Louise Brown, the first baby born through in vitro fertilisation (IVF), in England in 1978 attracted worldwide media attention. This article examines how the contemporary British news media framed this momentous event. Drawing on the example of the Daily Mail's coverage, it focuses on the way in which the British press depicted Louise's parents' emotions, marital relationship and social class in a context of political and economic crisis and resurgent social conservatism. The British press framed the Browns as ordinary and respectable, noting their work ethic, family orientation and moral values. The article argues that the human-interest angle that the press used to represent this story created a dominant narrative in which IVF was simply a means of helping married heterosexual couples have babies and that this established a frame for subsequent depictions of IVF, as well as contributing to its rapid normalisation

Unravelling mycorrhiza-induced wheat susceptibility to the English grain aphid Sitobion avenae

Arbuscular mycorrhizal (AM) fungi are root symbionts that can increase or decrease aphid growth rates and reproduction, but the reason by which this happens is unknown. To investigate the underlying mechanisms of this interaction, we examined the effect of AM fungi on the English Grain aphid (Sitobion avenae) development, reproduction, attraction, settlement and feeding behaviour on two naturally susceptible varieties Triticum aestivum (L.) variety Solstice and T. monococcum MDR037, and two naturally resistant lines, T. monococcum MDR045 and MDR049. Mycorrhizal colonisation increased the attractiveness of T. aestivum var. Solstice to aphids, but there was no effect on aphid development on this variety. Using the Electrical Penetration Graph (EPG) technique, we found that mycorrhizal colonisation increased aphid phloem feeding on T. monococcum MDR037 and MDR045, colonisation also increased growth rate and reproductive success of S. avenae on these varieties. Mycorrhizas increased vascular bundle size, demonstrating that these fungi can influence plant anatomy. We discuss if and how this could be related to an enhanced success rate in phloem feeding in two varieties. Overall, we present and discuss how mycorrhizal fungi can affect the feeding behaviour of S. avenae in wheat, inducing susceptibility in a resistant variety
