Nontechnical skills are critical for good anesthetic practice but are seldom addressed explicitly in clinical training. The purposes of this study were (1) to evaluate the reliability and validity of the observation-based assessment tool Nurse Anaesthetists' Non-Technical Skills system (N-ANTS) and (2) to evaluate the effect of training nurse anesthetist supervisors in the use of N-ANTS. This system comprises a global rating score, 4 categories, and 15 elements to rate nurse anesthetists' nontechnical skills...

There is a plethora of works on the origin and genesis of behavioral traditions in different animal species. Nevertheless, it still remains unclear as for which factors facilitate and which factors hinder the spreading those forms of behavior that are new for a population. Here, we present an analytical review on the topic, considering also the results of studies on 'culture' in animals and analyzing contradictions that arise when attempting to clarify the ethological mechanisms of cultural succession. The hypothesis of 'distributed social learning' is formulated, meaning that for spreading of complex behavioral stereotypes in a population the presence of few carriers of consistent stereotypes is enough under the condition that the rest of animals carry incomplete genetic programmes that start up these stereotypes...

BACKGROUND: Disparity in utilization of reproductive healthcare services between the urban poor and the urban non-poor households in the developing nations is well known. However, disparity may also exist within urban poor households. Our objective was to document the extent of disparity in reproductive healthcare utilization among the urban poor and to identify the socio-demographic determinants of underutilization with a view to characterizing this vulnerable subpopulation. METHODS: A survey of 16,221 households was conducted in 39 clusters from two large urban poor settlements in Delhi...

A new invader, the "tawny crazy ant", Nylanderia fulva (Hymenoptera: Formicidae; Formicinae), is displacing the red imported fire ant, Solenopsis invicta (Formicidae: Myrmicinae), in the southern U.S., likely through its superior chemical arsenal and communication. Alone, formic acid is unattractive, but this venom (= poison) acid powerfully synergizes attraction of tawny crazy ants to volatiles from the Dufour's gland secretion of N. fulva workers, including the two major components, undecane and 2-tridecanone...

Dead wood decomposition begins immediately after tree death and involves a large array of invertebrates. Ecological successions are still poorly known for saproxylic organisms, particularly in boreal forests. We investigated the use of dead wood as nesting sites for ants along a 60-yr postfire chronosequence in northeastern coniferous forests. We sampled a total of 1,625 pieces of dead wood, in which 263 ant nests were found. Overall, ant abundance increased during the first 30 yr after wildfire, and then declined...

Aenictus is the most species-rich genus of army ants in the subfamily Dorylinae and one of the most species rich ant genera in China and the world. In this paper, a new species of the Aenictusceylonicus group, Aenictushoelldobleri sp. n., is described and illustrated based on the worker caste. The new species occurs in the subtropical forests of south-east China and is morphologically most similar to Aenictushenanensis Li & Wang, 2005 and Aenictuswudangshanensis Wang, 2006. Aenictushoelldobleri sp. n. can be distinguished from both species by the shape of the subpetiolar process...

In the Guianese rainforest, we examined the impact of the presence of guano in and around a bat roosting site (a cave). We used ant communities as an indicator to evaluate this impact because they occupy a central place in the functioning of tropical rainforest ecosystems and they play different roles in the food web as they can be herbivores, generalists, scavengers or predators. The ant species richness around the cave did not differ from a control sample situated 500m away. Yet, the comparison of functional groups resulted in significantly greater numbers of detritivorous fungus-growing and predatory ant colonies around the cave compared to the control, the contrary being true for nectar and honeydew feeders...

BACKGROUND AND OBJECTIVES: We aimed to assess the incidence and evolution of left ventricular (LV) thrombi in a high-risk population of patients with LV systolic dysfunction after anterior myocardial infarction (ant-MI). We also compared the accuracy of transthoracic echocardiography (TTE) and cardiac magnetic resonance imaging with contrast-delayed enhancement (CMR-DE) in detecting LV thrombi. METHODS: We prospectively included 100 consecutive patients with LV ejection fraction (LVEF) <45% at the first TTE performed <7 days after ant-MI...

BACKGROUND: Obesity and anxiety during the perinatal period are common and associated with poor health outcomes for the mother and the child. Despite the well-documented health risks of both pregnancy obesity and anxiety, associations between the two have rarely been explored. With this review we aim to provide a systematic overview of the current state of evidence concerning associations between ante- and postnatal anxiety and pregnancy obesity, excessive gestational weight gain, and postpartum weight retention...

In this study we provide an update to the taxonomy of the ant genus Tetramorium Mayr in Madagascar. We report the first record of the Tetramoriumsetigerum species group in Madagascar and describe the only Malagasy representative as Tetramoriumcavernicola sp. n., which is known only from a cave in Ankarana. In addition, we provide an overview of the 19 proposed Malagasy species groups, and discuss their zoogeography and relationships to other groups and larger lineages within the hyper-diverse genus Tetramorium...

The accumulation of insoluble amyloid-beta (Aβ) peptides is associated with neurodegenerative disorders, such as Alzheimer's disease (AD). As essential tremor (ET) could involve neurodegenerative processes in the cerebellum, we quantified soluble and insoluble Aβ in cerebellar cortices from patients diagnosed with ET (n=9), compared to Controls (n=16) or individuals with Parkinson's disease (n=10). Although ante-mortem cognitive performance was not documented, all individuals included had the diagnosis of AD ruled out by a neuropathologist...

Three new ant-like stone beetle species: Neuraphes (Pararaphes) sichuanus sp. n., N. (P.) tuyuhun sp. n., and N. (P.) miniqinghaiensis sp. n. are described from Sichuan and Qinghai provinces of China. Another species, close to N. qinghaiensis Jałoszyński, is illustrated, but not formally described because of unclear diagnostic characters. The placement of Neuraphes species that inhabit mountain ranges surrounding Qinghai-Tibet Plateau in the subgenus Pararaphes is discussed and their distribution is summarized...

The Corinnidae of the western Pacific are revised. The formerly sparassid genus Anchognatha Thorell, 1881, and the gnaphosid genus Battalus Karsch, 1878, are transferred to the Castianeirinae. The Corinninae include only the introduced Creugas gulosus Thorell, 1878 and Medmassa christae sp. nov. from the northern Torres Strait islands. Medmassa pallipes (L. Koch, 1873) and Medmassa pusilla Simon, 1896 are newly synonymised with Creugas gulosus. The Castianeirinae from the Western Pacific including Australia includes Battalus Karsch, 1878, Copa Simon, 1886, Leichhardteus Raven & Baehr, 2013, Nyssus Walckenaer, 1805, Poecilipta Simon, 1897, and eight new genera: Disnyssus gen...

BACKGROUND: The postulated sites of perilymph fistulae involve otic capsule deficiencies, in particular, at the fissula ante fenestram. Histological studies have revealed this to be a channel extending from the middle ear, and becoming continuous with the inner ear medial to the anterior limit of the oval window. The relationship between a patent fissula and symptoms of perilymph fistula is contentious. OBJECTIVE: The understanding of the anatomy of the fissula ante fenestram is incomplete...

The evolution of reproductive division of labour and social life in social insects has lead to the emergence of several life-history traits and adaptations typical of larger organisms: social insect colonies can reach masses of several kilograms, they start reproducing only when they are several years old, and can live for decades. These features and the monopolization of reproduction by only one or few individuals in a colony should affect molecular evolution by reducing the effective population size. We tested this prediction by analysing genome-wide patterns of coding sequence polymorphism and divergence in eusocial vs...

Our study is about the essential oil of Citrus aurantium L. in Tunisia and its plant extract. The yield of this essential oil is 0, 56% but the yield of the extract of plant was 17.1% for the aqueous extract ant 18.3% for the ethanolic extract. The analysis of chemical composition by using GC and GC/MS showed the essential oil of C. aurantium L. species to be rich in monoterpenes such as α-terpineol, lianolyl acetate, linalool and limonene. The antifungal activity of this oil showed us an inhibition of the germination of mushrooms, in the same way we could note that the biologic activities are generally assigned to the chemotypes high content in oxygenated monoterpene...
