BACKGROUND: Hand hygiene is important in reducing healthcare-associated infections. The World Health Organization has defined 'five moments' when hand hygiene compliance is required. During 2013, New Zealand national data showed poor compliance with these moments by medical students. AIM: To improve medical students' compliance with the five moments. METHODS: In this prospective student-led quality improvement initiative, student investigators developed, implemented and evaluated a multi-modal intervention comprising a three-month social media campaign, a competition and an entertaining educational video...

The carving of a complex amalgam restoration may occasionally result in light proximal contact with the adjacent tooth. The purpose of this study was to investigate the strength of complex amalgam restorations repaired with a proximal slot amalgam preparation. Extracted human third molars of similar coronal size were sectioned 1 mm apical to the height of the contour using a saw and were randomly distributed into 9 groups of 10 teeth each. One pin was placed at each line angle of the flattened dentinal tooth surface...

Total mercury levels were measured in 42 commercial fish species caught off the Central Adriatic and Tyrrhenian coasts of Italy and in 6 aquaculture species. The study on wild fish covered species differing in living habitat and trophic level. The study on farmed fish covered marine and freshwater species from intensive and extensive aquaculture and their feed. Mercury levels were analyzed by Thermal Decomposition-Amalgamation-Atomic Absorption Spectrophotometry. Total mercury concentrations in the muscle of wild fish showed a high variability among species (0...

Mercury (Hg) is toxic and hazardous metal that causes natural disasters in the earth's crust. Exposure to Hg occurs via various routes; like oral (fish), inhalation, dental amalgams, and skin from cosmetics. In this review, we have discussed the sources of Hg and its potential for causing toxicity in humans. In addition, it's bio-chemical cycling in the environment; its systemic, immunotoxic, genotoxic/carcinogenic and teratogenic health effects; and the dietary influences; as well as the important considerations in risk assessment and management of Hg poisoning have been discussed in detail...

BACKGROUND: With the Minamata Convention the use of mercury will be phased down, and this undoubtedly will have an effect on dental treatment regimens and economic resources. Composite resin restorations are considered viable alternatives to amalgam fillings; however, these will not be covered completely by health insurance systems in many countries. Recently, a high-viscosity glass-ionomer cement (hvGIC) processed with a resinous coating (RC) has been introduced, and has been marketed as a restorative material in load-bearing Class I cavities (and in Class II cavities with limited size), thus serving as a possible alternative to amalgam fillings...

For investigators, physicians, and patients, the inability to identify therapies to improve clinical outcomes, particularly mortality, in patients with heart failure with preserved ejection fraction (HFpEF) has been particularly vexing and stands in stark contrast to the progress made in the treatment of patients with heart failure with reduced ejection fraction (HFrEF). This has prompted a return to the proverbial drawing board, forcing a reconsideration of long-held assumptions and paradigms. Despite different underlying etiologies, patients with HFrEF are generally responsive to several classes of medications that target the neurohormonal axis...

According to the received view, the transportation view, animal extrapolation consists in inductive prediction of the outcome of a mechanism in a target, based on an analogical mechanism in a model. Through an analysis of the failure of preclinical studies of TGN1412, an innovative drug, to predict the tragic consequences of its first-in-man trial in 2006, the received view is challenged by a proposed view of animal extrapolation, the chimera view. According to this view, animal extrapolation is based on a hypothesis about how human organisms work, supported by the amalgamation of results drawn from various experimental organisms, and only predicting the 'predictive grid', that is, a global framework of the effects to be expected...

BACKGROUND: The amalgam-associated oral lichenoid lesion (AAOLL) shows clinical and histopathological features similar to oral lichen planus (OLP). Molecular researches to improve knowledge of pathogenesis and clinical behavior of AAOLL are still scarce. OBJECTIVE: We investigated for the first time the use of LOH as a molecular approach for genetic characterization of AAOLL in comparison with OLP and evaluated the cell proliferation index. MATERIALS AND METHODS: The sample comprised nine AAOLLs, 10 OLPs and eight NOMs matched by patients' gender and age...

Selenium (Se) nanoparticles are often synthesized by anaerobes. However, anaerobic bacteria cannot be directly applied for bioremediation of contaminated top soil which is generally aerobic. In this study, a selenite-reducing bacterium, Citrobacter freundii Y9, demonstrated high selenite reducing power and produced elemental nano-selenium nanoparticles (nano-Se(0)) under both aerobic and anaerobic conditions. The biogenic nano-Se(0) converted 45.8-57.1% and 39.1-48.6% of elemental mercury (Hg(0)) in the contaminated soil to insoluble mercuric selenide (HgSe) under anaerobic and aerobic conditions, respectively...

Electronic medical records from first opinion equine veterinary practice may represent a unique resource for epidemiologic research. The appropriateness of this resource for risk factor analyses was explored as part of an investigation into clinical and pharmacologic risk factors for laminitis. Amalgamated medical records from seven UK practices were subjected to text mining to identify laminitis episodes, systemic or intra-synovial corticosteroid prescription, diseases known to affect laminitis risk and clinical signs or syndromes likely to lead to corticosteroid use...

Integration of anatomy and clinical teaching is a theoretical ideal, yet there is a worldwide paucity of such amalgamation. These teaching models provide support for medical trainees, an important element in Germany where orthopedic intern numbers have declined and anecdotal evidence suggests disinterest in orthopedics. The aim of the study was to develop an integrated anatomy-surgical course for undergraduate medical training, assess the model developed, and explore how medical students perceive orthopedics as a career...

Muscular hernias in the lower limb are a rare entity that have seldom been described in the literature, to the extent that the seminal paper on the subject remains a case series from 1929. Here, we present a case of tibialis anterior muscle hernia and discuss the aetiology behind the same. Furthermore, we attempt to amalgamate existing knowledge to provide some guidance for investigation and management of this important diagnostic consideration.
