Globally, acute abdominal pain (AAP) is one of the most common reasons for emergency admissions, yet little is known about how this patient group experiences the delivery of fundamental care across the acute care delivery chain. The purpose of this paper is to describe how patients with AAP experienced fundamental care across their acute care presentation, and to explicate the health professional behaviours, reported by patients, that contributed to their positive experiences.

A qualitative descriptive study, using repeated reflective interviews, was analysed thematically (n=10 patients).

Two themes were identified: developing genuine, caring relationships with health professionals and being informed about one’s care. Patients reported that health professionals established genuine professional–patient relationships despite the busy care environment but perceived this environment as impeding information-provision. Patients were typically accepting of a lack of information, whereas poor professional–patient relationships were seen as inexcusable.

To provide positive fundamental care experiences for patients with AAP, health professionals should establish caring relationships with patients, such as by using humour, being attentive, and acknowledging patients’ physical pain and emotional distress; and should inform patients about their care, including allowing patients to ask questions and taking time to answer those questions.

This is the first Australian study to explore the experiences of patients with AAP across the acute care delivery chain, using a novel method of repeated interviews, and to demonstrate how fundamental care can be delivered, in clinical practice, to ensure positive patient experiences.

This paper aims to elucidate the geochemical characteristics of the hydrothermally altered rocks with gold mineralization and the elemental transfers in hydrothermal alteration hosted in alkaline complex in Hongshan area, Taihang Orogen, North China, and preliminarily discuss the relationship between the gold mineralization and the hydrothermal alteration.

Based on detailed field investigation, sampling and petrographical observation, major oxides and trace elements of nine rock samples are analyzed, and the method of mass balance equation is used in calculation of the elemental transfer.

Three alteration stages in the Hongshan area are identified, which are the early, main and late alterations. The early one is characteristic of extensive pyritization in the complex, which is related to the mantle-derived magmas and occurs before gold mineralization. The main one is characterized by developing a great deal of altered rock in fracture zones with the gain of many elements and the loss of a few elements. The late one is dominated by limonitization, that is limonite replacing the early pyrite or Fe₂O₃ replacing FeO in rocks. In the main alteration, the altered rocks obviously gain fluid component (LOI, i.e. loss on ignition) and elements such as V, As, Rb, Au, La, Ce and Nd and total rare earth elements (REEs). Elements such as K, Fe, Cu, Zn, Y, Mo, Sb, W, Re and U are gained in some altered rocks. Na and Sr are lost in all altered rocks, and Th and Bi are lost in some ones in the meantime. The following elements: Si, Mg, Mn, Ca, Li, Sc, Cr, Co, Ni, Zr, Ag, Ba and Hg show either gain or loss in different altered rocks. Au is notably enriched in the hydrothermal alteration. The elemental gain or loss in the altered rocks indicates that the main mineralization develops extensive de-alkalinization, local potassic metasomatism, silicification or desilicification.

Consumer confidence in the European food industry has been shaken by a number of recent scandals due to food fraud and accidental contamination, reminding the authors that deliberate incidents can occur. Food defence methods aim to prevent or mitigate deliberate attacks on the food supply chain but are not a legal requirement. The purpose of this paper is to discuss how proactive and reactive food defence practices can help prevent or mitigate malicious attacks on the food chain and also food fraud, food crime and food safety. The authors look at how food defence differs from food safety and how it contributes to food supply chain integrity.

Food defence has been the focus of two different EU FP7 security projects, EDEN and SNIFFER. Food industry stakeholders participated in workshops and demonstrations on food defence and relevant technology was tested in different food production scenarios.

Food industry end-users reported a lack of knowledge regarding food defence practices. They wished for further guidelines and training on risk assessment as well as access to validated test methods. Novel detection tools and methods showed promise with authentication, identification, measurement, assessment and control at multiple levels of the food supply chain prior to distribution and retail.

The prevention of a contamination incident, prior to retail, costs less than dealing with a large foodborne disease outbreak. Food defence should therefore be integral to food supply chain integrity and not just an afterthought in the wake of an incident.

It is argued that food defence practices have a vital role to play across the board in unintentional and intentional food contamination incidents. The application of these methods can help ensure food supply chain integrity.
