Dark moments and the DAMA-CoGeNT puzzle
We consider the velocity dependence arising from scattering through dark multipole moments, and its effects on the consistency of the signals observed by DAMA and CoGeNT with the dark matter hypothesis. We focus on the effects of the experimental uncertainties on the fits, and show that the two experiments combined favor dark matter scattering with a velocity-dependent cross section over standard velocity and spin-independent scattering. When appropriate uncertainties are taken into account, we show that agreement of the two signals with each other and with the results of null experiments can be obtained
Implications of CoGeNT and DAMA for Light WIMP Dark Matter
In this paper, we study the recent excess of low energy events observed by
the CoGeNT collaboration, and discuss the possibility that these events
originate from the elastic scattering of a light (m_DM ~ 5-10 GeV) dark matter
particle. We find that such a dark matter candidate may also be capable of
generating the annual modulation reported by DAMA, as well as the small excess
recently reported by CDMS, without conflicting with the null results from other
experiments, such as XENON10. A dark matter interpretation of the CoGeNT and
DAMA observations favors a region of parameter space that is especially
attractive within the context of Asymmetric Dark Matter models. In such models,
the cosmological dark matter density arises from the baryon asymmetry of the
universe, naturally leading to the expectation that m_DM ~ 1-10 GeV. We also
discuss neutralino dark matter from extended supersymmetric frameworks, such as
the NMSSM. Lastly, we explore the implications of such a dark matter candidate
for indirect searches, and find that the prospects for detecting the neutrino
and gamma ray annihilation products of such a particle to be very encouraging.Comment: 16 pages, 14 figures. v2: references added, fig 4 and surrounding

The relationship of body mass index (BMI) to job performance, absenteeism and risk of eating disorder among hospital-based nurses
Obesity has been linked to job absenteeism and decreased job performance. Additionally, shift work may be related to abnormal eating in nurses. This study examines the relationship between body mass index, job performance, absenteeism, and eating disorder risk among nurses. Registered Nurses (nâŻ=âŻ63) participated in a survey that included the Work Limitations Questionnaire and the Eating Attitudes Test. Most participants were either overweight or obese. Significant correlations were noted between body mass index and job performance, and body mass index and risk of eating disorders. An understanding of how increased body mass index can affect a nurse\u27s job performance and wellness warrants continued attention from the nursing profession

Planned mode of birth after previous caesarean section and women's use of psychotropic medication in the first year postpartum:a population-based record linkage cohort study
Background:
Policy in many high-income settings supports giving pregnant women with previous caesarean section a choice between an elective repeat caesarean section (ERCS) or planning a vaginal birth after previous caesarean (VBAC), provided they have no contraindications to VBAC. Despite the potential for this choice to influence women's mental health, evidence about the associated effect to counsel women and identify potential targets for intervention is limited. This study investigated the association between planned mode of birth after previous caesarean and women's subsequent use of psychotropic medications.
Methods:
A population-based cohort study of 31 131 women with one or more previous caesarean sections who gave birth to a term singleton in Scotland between 2010 and 2015 with no prior psychotropic medications in the year before birth was conducted using linked Scottish national datasets. Cox regression was used to investigate the association between planned mode of birth and being dispensed psychotropic medications in the first year postpartum adjusted for socio-demographic, medical, pregnancy-related factors and breastfeeding.
Results:
Planned VBAC (n = 10 220) compared to ERCS (n = 20 911) was associated with a reduced risk of the mother being dispensed any psychotropic medication [adjusted hazard ratio (aHR) 0.85, 95% confidence interval (CI) 0.78â0.92], an antidepressant (aHR 0.83, 95% CI 0.76â0.90), and at least two consecutive antidepressants (aHR 0.83, 95% CI 0.75â0.91) in the first year postpartum.
Conclusions:
Women giving birth by ERCS were more likely than those having a planned VBAC to be dispensed psychotropic medication including antidepressants in the first year postpartum. Further research is needed to establish the reasons behind this new finding

A Survey to Guide the Emerging Role of Allied Health Teams in a Regional Tertiary Hospital Emergency Department
ABSTRACT
Purpose: A multidisciplinary allied health team has worked in The Townsville Hospital Emergency Department for seven years. Patients are referred to the allied health team by medical and nursing staff with the aim of reducing patient admission and improving patient outcomes. However, the type and number of referrals received by the allied health team suggest there is a lack of detailed interdisciplinary knowledge by the referrers. Therefore, the Emergency Department Allied Health Team surveyed other emergency department health professionals to ascertain their knowledge of allied health roles. The results will be used to develop education sessions to fill gaps in knowledge. Methods: A cross-sectional survey consisting of 22 true/false statements and demographic questions was developed by the Emergency Department Allied Health Team. Questions described some of the common triggers for referral to physiotherapy, occupational therapy, social work, and pharmacy staff in the emergency department at the Townsville Hospital. The survey was distributed opportunistically to nursing, medical and physician assistant staff at handover or education sessions. Descriptive statistics were used to describe the data and comparisons used chi squared tests. Results: The response rate for the survey was 63% (n=154), including 52 doctors (65%), 95 (59%) nursing staff, 3 physician assistants (100%), and 4 who did not state their discipline. Preferred responses were low for questions about occupational therapyâs ability to do home visits up to four weeks post emergency department discharge (37.7%), physiotherapistsâ necessity to perform mobility assessments (24.7%), identifying APINCH acronym as mnemonic for high risk drugs (35.7%) and the correct application of âclose the gapâ prescriptions (27.9%). Staff with more experience and prescribers were more likely to give the preferred response. Conclusions: Some gaps exist in doctorsâ, nursesâ, and physician assistantsâ knowledge of the roles of allied health in an emergency department. The knowledge gap decreases as staff experience in emergency departments increases. Therefore, for the allied health team in our emergency department to work at full scope of practice, these knowledge gaps need to be addressed. Our challenge now is to provide sustainable education on the role of allied health in a busy emergency department full of shift working and rotating staff being pulled by a myriad of contrasting priorities
Intestinal goblet cells sample and deliver lumenal antigens by regulated endocytic uptake and transcytosis
Intestinal goblet cells maintain the protective epithelial barrier through mucus secretion and yet sample lumenal substances for immune processing through formation of goblet cell associated antigen passages (GAPs). The cellular biology of GAPs and how these divergent processes are balanced and regulated by goblet cells remains unknown. Using high-resolution light and electron microscopy, we found that in mice, GAPs were formed by an acetylcholine (ACh)-dependent endocytic event remarkable for delivery of fluid-phase cargo retrograde into the trans-golgi network and across the cell by transcytosis - in addition to the expected transport of fluid-phase cargo by endosomes to multi-vesicular bodies and lysosomes. While ACh also induced goblet cells to secrete mucins, ACh-induced GAP formation and mucin secretion were functionally independent and mediated by different receptors and signaling pathways, enabling goblet cells to differentially regulate these processes to accommodate the dynamically changing demands of the mucosal environment for barrier maintenance and sampling of lumenal substances
