    Description: OBJECTIVES: The purpose of this survey was to study the beliefs, expectations, and satisfaction of Canadian parents regarding fever and the treatment of their febrile children.METHODS: A survey was developed exploring caregiver beliefs and treatment strategies, as well as expectations and satisfaction with medical care. Some items were modeled after previous studies to allow comparison. Caregivers with febrile children were recruited from 2005 to 2007 at 3 urgent care centers and emergency departments in Edmonton, Canada: a pediatric emergency department (n = 376), an urban urgent care center (n = 227), and a suburban urgent care clinic (n = 173).RESULTS: High and rapidly rising temperature, as well as physical symptoms associated with fever, caused concern in most parents surveyed. Seventy-four percent of parents felt that the elevated temperature from fever was dangerous and 90.3% always try to treat it. Forty degrees Celsius was the most commonly sited threshold for danger. Identifying the cause (80.6%) and seriousness (87.4%) of fever were the most com-mon stressors identified. Caregivers expected to receive information about the child's illness and appropriate treatment. The parents most often wanted information about febrile seizures and the potential dangers of febrile illness. Only 16.7% of caregivers expected anti-biotics. Nearly 92% of subjects were usually satisfied with medical care.CONCLUSIONS: Fever phobia continues to be a significant issue for Canadian parents. As a result, they treat fever aggressively and often seek medical attention. Good communication is important for medical staff caring for febrile children and typically leads to satisfied parents.

Wright, S.K. Ghosh Keywords: allergy 〈 rhinology; complications 〈 rhinology; rhinitis 〈 rhinology; rhino-sinusitis; specialties Objectives Our aim is to present data depicting geographical prescribing trends and expenditure related to topical nasal agent prescriptions across clinical commissioning groups (CCG's) in England. We assess if prescribing trends can act as a surrogate marker for allergic rhinitis (AR) and rhinosinusitis disease burden (RS). Design NHS England primary care prescriptions dispensed for topical drugs used in nasal allergy (BNF chapter 12.2.1) were accessed using OpenPrescribing beta software. Graphical data over a 5-year period was generated to highlight nationwide trends in prescribing and expenditure. Out of 211 CCG districts, the highest and lowest 40 prescribing rate CCG's were subdivided according to rural/urban output and geographical location to highlight specific regional trends. Two sampled, paired and unpaired t tests of unequal variance were performed to determine the significance of observed trends. Results The 5-year trend in prescription rate (mean yearly expenditure A[pounds sterling]40 725 258) for drugs used in nasal allergy marginally increased. Peak prescription was during months of high environmental pollen. Regardless of pollen season (June 2016 vs November 2015), CCG's of urban districts had significantly lower rates of prescribing (P [less than or equal to] .001). Amongst the 40 lowest and 40 highest prescribing rate CCG's, prescription rates fell significantly between months of high and low environmental pollen (P [less than or equal to] .0001). Regardless of pollen season, rural eastern and eastern coastal districts of England had persistently high rates of prescription. Conclusions This study shows marked geographical variation in prescribing for topical nasal agents in England. There is propensity for eastern districts to have higher rates of prescribing in England. Adopting prescribing trends as a surrogate marker for disease burden could allow allergy and endoscopic sinus surgery services to be concentrated to specific regions. This would provide more effective, economical treatment for both AR and RS.

    Description: We continue the program of structural differential geometry that begins with the notion of a tangent category, an axiomatization of structural aspects of the tangent functor on the category of smooth manifolds. In classical geometry, having an affine structure on a manifold is equivalent to having a flat torsion-free connection on its tangent bundle. This equivalence allows us to define a category of affine objects associated to a tangent category and we show that the resulting category is also a tangent category, as are several related categories. As a consequence of some of these ideas we also give two new characterizations of flat torsion-free connections. We also consider 2-categorical structure associated to the category of tangent categories and demonstrate that assignment of the tangent category of affine objects to a tangent category induces a 2-comonad. Finally, following work of Jubin, we consider monads and comonads on the category of affine objects associated to a tangent category. We show that there is a rich theory of monads and comonads in this setting as well as various distributive laws and mixed distributive laws relating these monads and comonads. Even in the category of smooth manifolds, several of these results are new or fill in gaps in the existing literature. Comment: Updated to reflect journal version

    Description: Harnessing the properties of biomolecules, such as peptides, adsorbed on inorganic surfaces is of interest to many cross-disciplinary areas of science, ranging from biomineralisation to nanomedicine. Key to advancing research in this area is determination of the peptide conformation(s) in its adsorbed state, at the aqueous interface. Molecular simulation is one such approach for accomplishing this goal. In this respect, use of temperature-based replica-exchange molecular dynamics (T-REMD) can yield enhanced sampling of the interfacial conformations, but does so at great computational expense, chiefly because of the need to include an explicit representation of water at the interface. Here, we investigate a number of more economical variations on REMD, chiefly those based on Replica Exchange with Solvent Tempering (REST), using the aqueous quartz-binding peptide S1-(100) -quartz interfacial system as a benchmark. We also incorporate additional implementation details specifically targeted at improving sampling of biomolecules at interfaces. We find the REST-based variants yield configurational sampling of the peptidesurface system comparable with T-REMD, at a fraction of the computational time and resource. Our findings also deliver novel insights into the binding behaviour of the S1 peptide at the quartz (100) surface that are consistent with available experimental data.

    Description: Secondary photon and secondary ion emission during energetic particle irradiation of solid surfaces is assumed to arise due to excitation and de‐excitation of sputtered particles originating from a collision cascade induced by the incident projectile. The excitation is postulated to occur by two alternative mechanisms: path (a), where excitation occurs at or very near the surface of the solid due to atom–atom or atom–electron collisions; and path (b), where excitation occurs as the sputtered particle leaves the solid, but is still under its influence so that electron exchange processes are permitted. Once the excited and/or ionized sputtered particle is formed nonradiative de‐excitation processes are then included in the discussion which allow the excited and/or ionized particle to be de‐excited and/or neutralized. The result of these nonradiative de‐excitation processes is shown to provide a possible channel for the formation of new excited ’’daughters’’ by the de‐excitation of the initial excited ’’parent’’. Depending on the initial excitation probability of the parent the new excited daughters are shown to contribute to various energy regions of the excited and/or ionized secondary particle energy distribution. A mathematical formalism is developed based on the neutral sputtered atom energy and velocity distributions assuming a collision cascade origin for these sputtered particles. By including various models for the excitation probability, and the survival probability for excited particles once formed to not undergo nonradiative de‐excitation the resulting energy and velocity distributions of the sputtered excited and/or ionized secondary particles are calculated. These distributions are found to be a function of the emission angle depending on the model assumed for the initial excitation. From this formalism the total excited secondary particle yield may be calculated. The mathematical expressions herein developed may be used to interpret present experimental data in such a manner that the initial assumptions regarding path (a) or path (b) excitation may or may not be substantiated. The formalism also suggests new experiments which can be performed to further test the excitation processes involved in excited and/or ionized secondary particle emission and thereby increase the understanding of the origin of these phenomena.

    Description: Secondary photon emission due to ion bombardment of Be metal foil by 200–3000 eV Kr + , Ar + , Ne + , O + 2 , and N + 2 was studied and the emission yield from four Be (I) and one Be (II) transitions as a function of incident ion energy was interpreted in terms of relevant excitation processes. A model based on a velocity dependent excitation process, the random linear collision cascade theory of sputtering; and making allowance for nonradiative de‐excitation of the excited sputtered atoms and/or ions, accounted for the observed energy dependent emission yields. The results of this model indicate that the secondary photon emission yield, Y ex i ( v m ), of a given emission line, i , can be expressed as Y ex i ( v m ) α J (μamp/cm 2 ) S (no./ion) exp[−( A / a ) i / v m ], where J is the incident ion current density, S the sputtering yield; v m is the velocity corresponding to the maximum transferred energy between the incident ion of energy E 1 , mass M 1 , and the target atom of mass M 2 , i.e., v m =[8 M 1 E 1 /( M 1 + M 2 ) 2 ] 1/2 ; ( A / a ) i is the effective nonradiative de‐excitation parameter for state i . Values for the ( A / a ) i parameters were found to be 1–3×10 7 cm/sec for the Be (I) and Be (II) states; a decrease to 5–7×10 6 cm/sec upon O + 2 bombardment was observed for the Be (I) states, while the value for the Be (II) state did not change.

    Description: Raman scattering was used to study the Fermi resonance of ν 1 and 2 ν 2 bands in gaseous CO 2 over the density interval of 15–534 amagat. Both vibrations were found to shift to lower frequency as density was increased. The resonance repulsion of the two bands was also found to increase with increasing density.

    Description: The in vitro antiproliferative effects of recombinant interferons (IFNs) alpha and gamma against the murine reticulum-cell sarcoma M5076 and the malignant melanoma B16 F10 were evaluated using the human hybrid IFN-alpha A/D (rHuIFN-alpha A/D), which is active on murine cells, and recombinant murine IFN gamma (rMuIFN-gamma). An isobologram analysis was used to evaluate the interactive antiproliferative effects of the recombinant IFNs on these two tumor cell lines. The data, in contrast to prior reports, indicate that rHuIFN-alpha A/D and rMuIFN-gamma interact in an additive rather than a synergistic manner against M5076 cells. When a similar analysis was performed on B16 F10 cells, synergy was obtained. Thus, either a synergistic or an additive antiproliferative effect can be obtained by combining IFN-alpha and IFN-gamma, depending upon the cell line used in the assay.
