The '5 Moments' approach is a time-space framework that delineates when hand hygiene should be performed and provides a resource for educators and auditors. It has become the dominant paradigm for organisations, practice, policy, and research in relation to hand hygiene. It is a concept that adopts the 'precautionary principle' that if the relative risk of a specific care task is unknown, a safe system must be to treat them on an equal level.

Background: The Infection Prevention Societies Competency Framework is a detailed tool that recognises the multi factorial work of Infection Prevention and Control Teams. This work often takes place in complex, chaotic and busy environments where non-compliance with policies, procedures and guidelines is endemic. As reductions in Healthcare Associated Infection became a health service priority the tone of Infection Prevention and Control (IPC) became increasingly uncompromising and punitive.

In heart, glucose and glycolysis are important for anaplerosis and potentially therefore for d-β-hydroxybutyrate (βHB) oxidation. As a glucose store, glycogen may also furnish anaplerosis. We determined the effects of glycogen content on βHB oxidation and glycolytic rates, and their downstream effects on energetics, in the isolated rat heart.

In two experiments, rats observed expert foragers in a laboratory foraging task. In both experiments, 12 towers with a food cup on top of each tower were placed in a circle. Six towers, marked with black and white stripes, had cups baited with cheese, and were located in randomly selected positions on successive trials.

Carbohydrate metabolism in heart failure shares similarities to that following hypoxic exposure, and is thought to maintain energy homoeostasis in the face of reduced O2 availability. As part of these in vivo adaptations during sustained hypoxia, the heart up-regulates and maintains a high glycolytic flux, but the underlying mechanism is still elusive. We followed the cardiac glycolytic responses to a chronic hypoxic (CH) intervention using [5-3H]-glucose labelling in combination with detailed and extensive enzymatic and metabolomic approaches to provide evidence of the underlying mechanism that allows heart survivability.

Outbreaks of infection create unique challenges to healthcare leaders and members of infection control teams who lead efforts to manage, control and resolve outbreaks. This is especially true during outbreaks of novel pathogens which may require atypical control methods reflecting the unknowns inherent in such situations. Healthcare providers within the UK have adopted various structures and models of infection prevention and control (IPC) service reflecting the individual needs of different organisations.

Foot problems and suboptimal footwear are risk factors for falls among the elderly. Footwear choice may, therefore, be important for people with balance impairment following stroke, but little is known about their experience. This study explored foot problems experienced following stroke, factors influencing footwear choices and views of footwear in use.

Health care-associated infection is a real and relative risk within the realm of organ donation. Despite detailed guidance from the Advisory Committee on the Safety of Blood, Tissues and Organs on the microbiological safety of human organs, tissues and cells used in transplantation, the topic has received limited exposure in the literature. This paper will give a context to the Safety of Blood, Tissues and Organs guidance, outline the key recommendations for mandatory/recommended screening and provide a summary of infections that may be present at the time of donation that require careful risk assessment.

There is abundant evidence that domestic dogs (Canis familiaris) readily follow pointing and other cues given by humans. But there has been much less research into the question of whether dogs can learn to discriminate between different humans giving repeated honest or dishonest cues as to food location, by ignoring the information imparted by the deceiver. Prior research has demonstrated that even after repeated exposures to deceptive cues with respect to food location, dogs failed to learn to ignore those cues completely.

Key Points: The cardiac metabolic reprogramming seen in heart diseases such as myocardial infarction and hypertrophy shares similarities with that seen in chronic hypoxia, but understanding of how the hypoxic heart responds to further hypoxic challenge - hypoxic tolerance - is limited. The pyruvate dehydrogenase complex serves to control irreversible decarboxylation of pyruvate within mitochondria, and is a key regulator of substrate metabolism, potentially regulating hypoxic tolerance. Acute activation of the pyruvate dehydrogenase complex did not improve cardiac function during acute hypoxia; however, simultaneous activation of the pyruvate dehydrogenase complex during chronic hypoxic exposure improved tolerance to subsequent acute hypoxia.

Background: Ill-fitting shoes have been implicated as a risk factor for falls but research to date has focused on people with arthritis, diabetes and the general older population; little is known about people with neurological conditions. This survey for people with stroke and Parkinson's explored people's choice of indoor and outdoor footwear, foot problems and fall history.

Methods: Following ethical approval, 1000 anonymous postal questionnaires were distributed to health professionals, leads of Parkinson's UK groups and stroke clubs in the wider Southampton area, UK.

Ketone bodies are the most energy-efficient fuel and yield more ATP per mole of substrate than pyruvate and increase the free energy released from ATP hydrolysis. Elevation of circulating ketones via high-fat, low-carbohydrate diets has been used for the treatment of drug-refractory epilepsy and for neurodegenerative diseases, such as Parkinson's disease. Ketones may also be beneficial for muscle and brain in times of stress, such as endurance exercise.

Hypoxia-inducible factor (HIF) appears to function as a global master regulator of cellular and systemic responses to hypoxia. HIF pathway manipulation is of therapeutic interest; however, global systemic upregulation of HIF may have as yet unknown effects on multiple processes. We used a mouse model of Chuvash polycythemia (CP), a rare genetic disorder that modestly increases expression of HIF target genes in normoxia, to understand what these effects might be within the heart.

In 4 experiments, rats searched for food located on top of 4 of 16 towers which were arranged in a 4 × 4 matrix. The location of the baited towers was cued by visual landmark cues (the baited towers were striped, the others white) and by pattern cues (the baited towers were located in a 2 × 2 pattern within the larger 4 × 4 matrix) or simply by pattern cues without visual landmark cues. In 3 of the experiments, visual cues, after being paired with pattern cues, were removed altogether (Experiment 1), put into competition with pattern cues (Experiment 2), or made noninformative (Experiment 3).

The role of peroxisome proliferator-activated receptor α (PPARα)-mediated metabolic remodeling in cardiac adaptation to hypoxia has yet to be defined. Here, mice were housed in hypoxia for 3 wk before in vivo contractile function was measured using cine MRI. In isolated, perfused hearts, energetics were measured using (31)P magnetic resonance spectroscopy (MRS), and glycolysis and fatty acid oxidation were measured using [(3)H] labeling.

The financial and human costs of healthcare-associated infections have prompted many local and national policies/guidelines aimed at controlling or preventing infection. However, the language used in the discourse of this are of practice tends to lack objectivity and may make unachievable demands of staff. This article explores how such language can negatively affect staff behaviour and drive poor practice underground.

Key Points: Adaptation to hypoxia makes the heart more oxygen efficient, by metabolising more glucose. In contrast, type 2 diabetes makes the heart metabolise more fatty acids. Diabetes increases the chances of the heart being exposed to hypoxia, but whether the diabetic heart can adapt and respond is unknown.

Healthcare-associated infection (HCAI) is a major patient safety concern and is associated with morbidity, mortality and increased healthcare costs. Prevention and control requires a multi-modal approach, but the individual's accountability and rigorous application of standard infection prevention and control behaviours is at its core. The third instalment of the epic3 guidance ( Loveday et al, 2014a ) provided the evidence and advanced the importance of hand-hygiene behaviour, the use of non-sterile gloves and environmental cleanliness.

Introduction: Healthcare-associated infection is a major patient safety concern. Hand hygiene is widely thought to be the single most important measure to affect reductions but compliance is problematic. Producing policies that clearly outline the responsibilities of staff is seen as a key way to instil accountability and improve performance.

The chronic administration of the β-adrenoreceptor agonist isoproterenol (IsoP) is used in animals to study the mechanisms of cardiac hypertrophy and failure associated with a sustained increase in circulating catecholamines. Time-dependent changes in myocardial blood flow (MBF), morphological and functional parameters were assessed in rats in vivo using multimodal cardiac MRI. Energy metabolism, oxidative stress and the nitric oxide (NO) pathway were evaluated in isolated perfused rat hearts following 7 days of treatment.

Background: To study the pathogenesis of diabetic cardiomyopathy, reliable animal models of type 2 diabetes are required. Physiologically relevant rodent models are needed, which not only replicate the human pathology but also mimic the disease process. Here we characterised cardiac metabolic abnormalities, and investigated the optimal experimental approach for inducing disease, in a new model of type 2 diabetes.
