Abstract
Background:Glucocorticoids (GC) are long established as a first line treatment in patients with idiopathic inflammatory myopathy (IIM), in which high dose, long duration treatment is often required. GC usage is associated with a wide range of adverse effects (AEs). The patient perspective on the risks and benefits of GCs is not well studied and no prior studies assesses this issue in IIM patients (1).Objectives:To describe the perspective of IIM patients on GC treatment.Methods:We deployed an online survey distributed using the Myositis UK page on Healthunlocked.com, an online social network for health, with approximately 450 patients registered. Patients with diagnosed IIM were invited to take part on an anonymised basis. Respondents were asked to grade the severity on a Likert scale (1 to 5) of all AEs experienced in relation to GC. Additionally, respondents were asked to write about their concerns and to rate their overall experience with GC treatment.Results:In total, 122 completed surveys were received. Forty five percent (55/122) of respondents had dermatomyositis, 27% (33/122) polymyositis, 10% (12/122) anti-synthetase syndrome, 18% (22/122) other inflammatory myopathies. Seventy-nine percent (96/122) of respondents were female and the mean age overall was 50 years (SD [standard deviation] 14).The median reported current daily dose of prednisolone was 15 mg and median treatment duration was 5.3 years at the time of survey completion. Females were more likely to stay on GCs for longer than males (5.4vs4.7 years, p=0.046).Table 1.Mean severity and frequency for each adverse effect.All respondents(n=122)Male(n=26)Female(n=96)<60 years(n=89)≥60 years(n=33)Moon face3.3 (1.9)2 (2.1)*3.6 (1.7)*3.5 (1.8)2.7 (2)Weight gain3.4 (1.7)3.1 (1.6)3.4 (1.8)3.5 (1.7)3.1 (1.9)Acne1.1 (1.5)1 (1.5)1.2 (1.6)1.3 (1.6)0.7 (1.2)Hair loss2 (1.8)0.8 (1.4)*2.4 (1.8)*2.2 (1.8)**1.5 (1.9)**Facial hair2.1 (1.8)0.7 (1.3)*2.5 (1.8)*2.3 (1.8)1.7 (1.8)Thin skin2.2 (1.9)1.8 (2)2.3 (1.8)2.2 (1.9)2.3 (1.9)Bruising2.2 (1.7)2.1 (1.9)2.2 (1.7)2.2 (1.7)2 (1.9)Stretch marks1.3 (1.9)0.9 (1.5)1.4 (1.8)1.5 (1.9)**0.6 (1.2)**Nausea1.4 (1.7)1.6 (1.8)1.4 (1.6)1.5 (1.6)1.2 (1.7)Heartburn1.9 (1.8)1.8 (1.9)1.9 (1.8)2 (1.8)1.5 (1.8)Hunger2.8 (1.7)2.2 (1.9)*3 (1.6)*3 (1.6)2.4 (2)Mood swings2.7 (1.6)2.1 (1.8)2.7 (1.5)2.8 (1.6)2.6 (1.6)Sleep disturbances3.1 (1.5)2.9 (1.7)3.2 (1.4)3.2 (1.5)3 (1.5)Cataracts0.6 (1.3)1.1 (1.8)0.5 (1.1)0.5 (1.2)1 (1.6)Glaucoma0.4 (1.1)0.6 (1.5)0.3 (0.9)0.4 (1)0.4 (1)Hypertension1.6 (1.7)1.8 (1.7)1.5 (1.7)1.5 (1.7)1.8 (1.8)Diabetes0.8 (1.6)1 (1.6)0.8 (1.6)0.7 (1.5)1 (1.8)Water retention2.2 (1.7)1.7 (1.6)2.3 (1.8)2.3 (1.8)1.9 (1.6)Infections2.2 (1.7)2.2 (1.8)2.2 (1.7)2.2 (1.7)2.1 (1.7)Fractures0.5 (1.1)0.5 (1.2)0.5 (1.1)0.5 (1.6)0.5 (1.1)Mean severity on a Likert scale (0-5), mean (SD);*p<0.05, male vs female; **p<0.05, <60 years vs ≥60 years.Frequency (number of patients reporting adverse effect as present), heatmap:White (0-33%), light grey (33-66%), dark grey (66-100%).The mean number of reported AEs to GC treatment per patient was 12 (SD 5).

The three most commonly experienced AEs were: sleep disturbance (93%), mood swings (86%) and weight gain (86%). Only 54% of respondents agreed that the information given about the potential risks of GC treatment was adequate.

Abstract
Alpha 2 agonists are appreciated drugs designed for the peri-operative period, because of their anxiolytic, sedative and analgesic properties. However, they are usually avoided during scoliosis surgery, a longlasting major procedure involving healthy patients, because of their potential effects on Somatosensory and Motorevoked potentials. The absence ofrecommendations suggests that their effects on evoked potentials are still unclear. Thus, we tried in this narrative review to identify the literature representative of the effects of clonidine and dexmedetomidine on evoked potentials, on human beings, published between 1988 and 2015 in English or French, using GOOGLE SCHOLAR and PUBMED. Paucity of literature prevented any conclusion about Clonidine's effects on evoked potentials, but no data suggested a noxious effect of Clonidine on evoked potentials, used in oral premedication (300 μg) or during the procedure (2 to 5 μg/kg). If literature was more extensive for dexmedetomidine, studies were still controversial. Although the majority of the studies did not find statistically significant differences concerning the effects of this drug on evoked potentials (loading dose of 0.3 to 1 μg/ kg followed by continuous infusion of 0.3 to 0.8 μg/kg/h), 2 case reports and 2 studies described substantial decreases. However, dexmedetomidine's shorter duration of action allowed a quick return to basal situation within an hour. In conclusion, more studies are needed in order to evaluate the effects of alpha 2 agonists on evoked potentials and to assess the safety of their use in this setting.

Abstract
Protein arginine methyltransferases (PRMTs) methylate arginine residues on histones and target transcription factors that play critical roles in many cellular processes, including gene transcription, mRNA splicing, proliferation, and differentiation. Recent studies have linked PRMT-dependent epigenetic marks and modifications to carcinogenesis and metastasis in cancer. However, the role of PRMT2-dependent signaling in breast cancer remains obscure. We demonstrate PRMT2 mRNA expression was significantly decreased in breast cancer relative to normal breast. Gene expression profiling, Ingenuity and protein-protein interaction network analysis after PRMT2-short interfering RNA transfection into MCF-7 cells, revealed that PRMT2-dependent gene expression is involved in cell-cycle regulation and checkpoint control, chromosomal instability, DNA repair, and carcinogenesis. For example, PRMT2 depletion achieved the following: 1) increased p21 and decreased cyclinD1 expression in (several) breast cancer cell lines, 2) decreased cell migration, 3) induced an increase in nucleotide excision repair and homologous recombination DNA repair, and 4) increased the probability of distance metastasis free survival (DMFS). The expression of PRMT2 and retinoid-related orphan receptor-γ (RORγ) is inversely correlated in estrogen receptor-positive breast cancer and increased RORγ expression increases DMFS. Furthermore, we found decreased expression of the PRMT2-dependent signature is significantly associated with increased probability of DMFS. Finally, weighted gene coexpression network analysis demonstrated a significant correlation between PRMT2-dependent genes and cell-cycle checkpoint, kinetochore, and DNA repair circuits. Strikingly, these PRMT2-dependent circuits are correlated with pan-cancer metagene signatures associated with epithelial-mesenchymal transition and chromosomal instability. This study demonstrates the role and significant correlation between a histone methyltransferase (PRMT2)-dependent signature, RORγ, the cell-cycle regulation, DNA repair circuits, and breast cancer survival outcomes.

Abstract
This paper reports on a qualitative study of the use of an expert system developed for the British telephone triage service NHS Direct. This system, known as CAS, is designed to standardise and control the interaction between NHS Direct nurses and callers. The paper shows, however, that in practice the nurses use CAS in a range of ways and, in so doing, privilege their own expertise and deliver an individualised service. The paper concludes by arguing that NHS Direct management's policy of using CAS as a means of standardising service delivery will achieve only limited success due not only to the professional ideology of nursing but also to the fact that rule-based expert systems capture only part of what 'experts' do.

Abstract
In humans, ten Toll-like receptor (TLR) paralogues sense molecular components of microbes, initiating the production of cytokine mediators that create the inflammatory response. Using N-ethyl-N-nitrosourea, we induced a germline mutation called Lps2, which abolishes cytokine responses to double-stranded RNA and severely impairs responses to the endotoxin lipopolysaccharide (LPS), indicating that TLR3 and TLR4 might share a specific, proximal transducer. Here we identify the Lps2 mutation: a distal frameshift error in a Toll/interleukin-1 receptor/resistance (TIR) adaptor protein known as Trif or Ticam-1. Trif(Lps2) homozygotes are markedly resistant to the toxic effects of LPS, and are hypersusceptible to mouse cytomegalovirus, failing to produce type I interferons when infected. Compound homozygosity for mutations at Trif and MyD88 (a cytoplasmic TIR-domain-containing adaptor protein) loci ablates all responses to LPS, indicating that only two signalling pathways emanate from the LPS receptor. However, a Trif-independent cell population is detectable when Trif(Lps2) mutant macrophages are stimulated with LPS. This reveals that an alternative MyD88-dependent 'adaptor X' pathway is present in some, but not all, macrophages, and implies afferent immune specialization.

Abstract
Port-wine stains (nevus flammeus, port-wine nevus) are congenital vascular lesions that have psychological and physiological implications for patient care. The location and size of these lesions can lead to complications related to anesthetic management. Facial lesions have the most profound psychological effect on the patient with respect to behavior alterations and reluctance to disclose the lesion's presence. Covering makeup has become increasingly effective not only in concealing the lesion, but also in being nearly undetectable during routine examination. Issues such as agent choice, surgical position, frequency of positioning evaluation, and choice of intravenous fluid should be considered when caring for a patient with a port-wine stain. In this case study the authors describe the anesthesia implications and outcome in a patient who refused to disclose her port-wine lesion in the preoperative interview and who ignored preoperative instructions to remove all makeup before presenting for surgery.

Abstract
Mating has been shown in many species to provoke the release of oxytocin (OT). In our study, various stimuli were applied to mares to study release of OT and prostaglandin F(2alpha) (PGF(2alpha)) associated with mating. Blood samples were collected from mares around the time of teasing both in oestrus and dioestrus and at mating. For comparison, blood samples were also collected at the time of manual manipulation of the genital tract and after intrauterine infusion of 500 ml phosphate buffered saline (PBS). Additional samples were collected 16 to 18 h after mating. Mating caused a significant increase in OT in all mares and teasing caused a significant OT response in 6 of 10 oestrous and 3 of 5 dioestrous mares. However, mating and teasing had no significant effect on concentrations of 15-keto-13,14-dihydro-PGF(2alpha) (PGFM). Manual manipulation of the clitoris, vagina and cervix caused significant OT release in all mares and intrauterine infusion of 500 ml PBS caused significant OT release in three of the five mares. However, only one mare had a significant PGF(2alpha) response during manual manipulation and only one responded positively to intrauterine infusion of 500 ml PBS. We concluded that events around mating, including stimulation of the genital tract and uterine distension, often caused an increase in circulating concentrations of OT but only rarely in PGFM.

Abstract
Variations in hysterectomy rates have been associated with assorted physician and patient characteristics, and the disproportionate rate of hysterectomies in African American women has been attributed to a higher prevalence of leiomyomas. The role of women's beliefs and attitudes toward hysterectomy and participation in decision making for medical treatment has not been explored as a source of variance. The purposes of this qualitative study were to explore these constructs in a triethnic sample of women to understand beliefs, attitudes, and decision-making preferences among underserved women; to facilitate development of a quantitative survey; and to inform development of interventions to assist women with such medical decisions. Twenty-three focus groups were conducted with 148 women from community sites and public health clinics. Thirteen self-identified lesbians participated in three groups. Analysis of audiotaped transcripts yielded four main themes: perceived outcomes of hysterectomy, perceived views of men/partners, opinions about healthcare providers, decision-making process. Across groups, the women expressed similar expectations from hysterectomy, differing only in the degree to which dimensions were emphasized. The women thought men perceived women with hysterectomy as less desirable for reasons unrelated to childbearing. Attitudes toward physicians were negative except among Hispanic women. All women expressed a strong desire to be involved in elective treatment decisions and would discuss their choice with important others. Implications for intervention development include enhancing women's skills and confidence to evaluate treatment options and to interact with physicians around treatment choices and creation of portable educational components for important others.

Abstract
It has been suggested that oxytocin is involved in sperm transport and motility in domestic animals. Immunoreactive oxytocin was measured in seminal fractions (pre-ejaculatory fluid, seminal plasma, gel and sperm) and in extracts of testis and epididymis from stallions. In addition, sections of gonadal tissue from stallions were immunostained for the presence of oxytocin and its neurophysin. Oxytocin was detected in all of the seminal fractions, being highest in the gel. It was also present in washed, lysed sperm and in extracts from the testis and epididymis. Immunostaining for oxytocin was present in occasional interstitial cells in the testis and in the epididymal epithelium and smooth muscle. However, immunostaining for neurophysin was detected in a few interstitial cells in the testis of only 1 of 8 stallions and was absent from all areas of the epididymis. These data demonstrate for the first time the presence of oxytocin in stallion semen and gonadal tissue; however, lack of immunostaining for neurophysin indicated that it was unlikely that there was local synthesis within the gonads.

Abstract
The results reported here are based upon a survey of the nutritional attitudes and practices of a sample of adults aged between 18 and 74 years. The scaled responses to two inventories of statements were subjected to a factor analysis in order to assess the extent to which it is possible to identify a set of coherent dimensions which underly the range of "surface" issues which figure consistently in the sociological literature. The results broadly confirm the utility of the inventories, and do suggest the presence of a series of underlying themes, some of which are very much along anticipated lines. However, one theme, that of deference to what might be thought of as "authoritative agencies" within the food system, was less expected, and deserves further attention. Additionally, selected factors were aggregated by summing the scores of their component variables, and correlated with the key independent variables of age, sex and social class, with a view to identifying the social profiles of their adherents. The results obtained were by no means clear cut, with a number of the anticipated features of such profiles being absent. Moreover, where the profiles were as anticipated, the correlations, although statistically significant, were relatively weak. This raised the issue of whether such an outcome was a methodological artefact, or a reflection of the possibility that differences in nutritional attitudes and practices are shaped by a range of lifestyle variables which do not coincide with conventional indicators of social differentiation.

Abstract
Public health initiatives aimed at changing the nation's diet rely on simple messages to persuade people to eat more from certain food groups and less from others. The underlying rationale of this strategy is that control is located firmly in the hands of the individual who can 'choose' health by following the guidelines. The research reported in this article found high levels of public awareness of nutritional guidelines, and a sense of personal control over health. However, accounts of other health-related agendas showed that being in control may mean choosing to become fitter or slimmer. Within these pursuits, nutritional concerns were prioritized only in so far as they were seen to serve the attainment of a desired body shape. Health professionals need to be aware that nutritional guidelines may be competing with other mediating factors along the chosen route to health.

Abstract
The effects of cold exposure on arterial and mammary venous concentrations of thyroxine and oestrone sulphate, and on mammary blood flow, were measured in goats during different stages of pregnancy and lactation. There were no significant differences in net mammary uptake of thyroxine in four non-pregnant lactating goats exposed for 30 h to cold (-3 +/- 2 degrees C) or control (20 +/- 2 degrees C) temperatures. Cold exposure for 30 h of six lactating goats (approximately 85 d pregnant) stimulated a net mammary release into the circulation of oestrone sulphate (mean 294 ng/min); plasma cortisol concentrations also increased. Cold exposure at approximately 30 d of pregnancy increased cortisol concentrations but had no effect on release of oestrone sulphate.

Abstract
Following the observation that the concentration of progesterone in goats' milk differs appreciably according to the specificity of the antiserum used in a non-extraction (direct) radioimmunoassay, experiments were carried out to find an explanation for these results. Milk and plasma samples were collected during the oestrous cycle and during an equivalent period of pregnancy after a fertile mating. Samples were analyzed by a direct radioimmunoassay using two antisera, 18/3 which is highly specific for progesterone and 465/6 which is less specific, and by radioimmunoassay of fractions isolated by thin-layer chromatography (TLC). Values obtained for milk and plasma samples collected during the oestrous cycle and early pregnancy were similar, except that values for milk samples measured with antiserum 465/6 were higher in pregnancy compared to those obtained during the oestrous cycle. Values obtained for milk and plasma with antiserum 465/6 were significantly higher than those obtained with 18/3 (P less than 0.001). After TLC this difference was found to be due principally to the presence of compound(s) with chromatographic properties identical to 5-pregnanedione(s). A comparison of the concentration measured in arterial and mammary venous plasma and in milk showed that about 25% of progesterone (5.7 nmol/min) was extracted by the mammary gland, and that substantial amounts of immunoreactive metabolites of progesterone are secreted into milk with only small quantities being transferred into mammary vein plasma.

Abstract
Vesicular stomatitis virus forms discrete, microscopic plaques in stationary cultures of the WISH amnion cell line. Microplaque formation is rapid, reproducible, and easily quantitated, occurs at temperatures ranging from 33 to 40 degrees C, and does not require a semisolid overlay. WISH cells, however, are less sensitive to vesicular stomatitis virus than are chicken embryo, 3T6, or Vero cells. WISH amnion cells also are highly sensitive to the antiviral effects of human interferon, and a quantitative human interferon assay, based on vesicular stomatitis virus plaque reduction in WISH cells, is described. This interferon assay can be performed within 1 day, uses a liquid overlay medium, does not require a vital stain, is as sensitive as other methods that use diploid cell strains, and is performed in a microtiter system.

Abstract
Incubation periods and nest contents of three species of chelid tortoises in
northern Victoria were recorded. Mean incubation period for eggs of Emydura macquari
(Cuvier) was 75 days and average number of eggs per nest was 15.7; for Chelodina
longicollis (Shaw), 138 days and 10.7 eggs per nest; for Chelodina expansa Gray,
normally exceeding 324 days and 15.4 eggs per nest. In abnormal seasons C. expansa
hatchlings may emerge from the nest in less than 193 days or more than 522 days after
eggs were deposited.
Eggs artificially incubated at 30�C consistently develop more quickly than those
at lower temperatures under natural conditions. In the field nest temperatures closely
approximate the mean daily air temperature.
Embryos of C. expansa are tolerant to nest temperatures ranging from 4.9�C
minimum to 29.6�C maximum. The other species are subject to variations of about
15 degC with up to 8.5 degC variation being recorded in 1 day.
Development of early embryos approximated that recorded for cryptodire
tortoises. However, there are large individual differences in the period of incubation
needed for specific stages to be reached, especially between embryos of the short-necked
and long-necked species of these pleurodire tortoises.
It is suggested that differences in the anatomy of their eggs are the main factors
in the different incubation periods between short-necked and long-necked species.
