Painting pain: An interpretative phenomenological analysis of representations of living with chronic pain

Objective: This study examines patients’ pictorial representations of their chronic pain, alongside their accounts of those images, in order to help our understanding of their lived experience of the condition. Method: The sample comprises seven women in middle adulthood from southern England. They began by drawing what their pain felt like and were then interviewed about their portrayals. The interviews were analyzed with interpretative phenomenological analysis. Results: The participants produce strong, vivid, abstract pictures. In many of the pictures, the pain is objectified as punitive and sinister. This is enhanced through the use of stark colours of red and black. Paintings also often have a temporal element, showing either the movement from self before pain to self since the pain had started, or pointing to aspirations for the possible relief of pain in the future. The analysis of the images is grounded in the participants’ accounts of them. Conclusion: The images and accounts provide a powerful insight into the internal world of the pain sufferer and the subjective experience of chronic pain. We link this work to other attempts to represent patients’ pain and point to the particular contribution our work makes. We make some suggestions for subsequent research following on from what is presented here and we also argue that the methodology outlined in the paper offers considerable potential for research on other health conditions

Superior epigastric artery pseudoaneurysm- a rare complication of chest drain insertion in coronary artery bypass grafting

BACKGROUND: Although chest drain insertion during coronary artery bypass grafting is a fairly standard procedure, however it may result in extremely rare complications. CASE PRESENTATION: This is the first case being reported that demonstrates a pseudoaneurysm of superior epigastric artery resulting from chest drain insertion following coronary artery bypass grafting. CONCLUSION: Adequate caution should be used along with good understanding of the anatomical landmarks during apparently simple and standard operative procedures

Polyornithine-based polyplexes to boost effective gene silencing in CNS disorders.

Gene silencing therapies have successfully suppressed the translation of target proteins, a strategy that holds great promise for the treatment of central nervous system (CNS) disorders. Advances in the current knowledge on multimolecular delivery vehicles are concentrated on overcoming the difficulties in delivery of small interfering (si)RNA to target tissues, which include anatomical accessibility, slow diffusion, safety concerns, and the requirement for specific cell uptake within the unique environment of the CNS. The present work addressed these challenges through the implementation of polyornithine derivatives in the construction of polyplexes used as non-viral siRNA delivery vectors. Physicochemical and biological characterization revealed biodegradability and biocompatibility of our polyornithine-based system and the ability to silence gene expression in primary oligodendrocyte progenitor cells (OPCs) effectively. In summary, the well-defined properties and neurological compatibility of this polypeptide-based platform highlight its potential utility in the treatment of CNS disorders

Mosquito Abundance, Bed net Coverage and Other Factors Associated with Variations in Sporozoite Infectivity Rates in Four Villages of Rural Tanzania.

Entomological surveys are of great importance in decision-making processes regarding malaria control strategies because they help to identify associations between vector abundance both species-specific ecology and disease intervention factors associated with malaria transmission. Sporozoite infectivity rates, mosquito host blood meal source, bed net coverage and mosquito abundance were assessed in this study. A longitudinal survey was conducted in four villages in two regions of Tanzania. Malaria vectors were sampled using the CDC light trap and pyrethrum spray catch methods. In each village, ten paired houses were selected for mosquitoes sampling. Sampling was done in fortnight case and study was undertaken for six months in both Kilimanjaro (Northern Tanzania) and Dodoma (Central Tanzania) regions. A total of 6,883 mosquitoes were collected including: 5,628 (81.8%) Anopheles arabiensis, 1,100 (15.9%) Culex quinquefasciatus, 89 (1.4%) Anopheles funestus, and 66 (0.9%) Anopheles gambiae s.s. Of the total mosquitoes collected 3,861 were captured by CDC light trap and 3,022 by the pyrethrum spray catch method. The overall light trap: spray catch ratio was 1.3:1. Mosquito densities per room were 96.5 and 75.5 for light trap and pyrethrum spray catch respectively. Mosquito infectivity rates between villages that have high proportion of bed net owners and those without bed nets was significant (P < 0.001) and there was a significant difference in sporozoite rates between households with and without bed nets in these four villages (P < 0.001). Malaria remains a major problem in the study areas characterized as low transmission sites. Further studies are required to establish the annual entomological inoculation rates and to observe the annual parasitaemia dynamics in these communities. Outdoor mosquitoes collection should also be considered

Robotic milking technologies and renegotiating situated ethical relationships on UK dairy farms

Robotic or automatic milking systems (AMS) are novel technologies that take over the labor of dairy farming and reduce the need for human-animal interactions. Because robotic milking involves the replacement of 'conventional' twice-a-day milking managed by people with a system that supposedly allows cows the freedom to be milked automatically whenever they choose, some claim robotic milking has health and welfare benefits for cows, increases productivity, and has lifestyle advantages for dairy farmers. This paper examines how established ethical relations on dairy farms are unsettled by the intervention of a radically different technology such as AMS. The renegotiation of ethical relationships is thus an important dimension of how the actors involved are re-assembled around a new technology. The paper draws on in-depth research on UK dairy farms comparing those using conventional milking technologies with those using AMS. We explore the situated ethical relations that are negotiated in practice, focusing on the contingent and complex nature of human-animal-technology interactions. We show that ethical relations are situated and emergent, and that as the identities, roles, and subjectivities of humans and animals are unsettled through the intervention of a new technology, the ethical relations also shift. © 2013 Springer Science+Business Media Dordrecht

Robot life: simulation and participation in the study of evolution and social behavior.

This paper explores the case of using robots to simulate evolution, in particular the case of Hamilton's Law. The uses of robots raises several questions that this paper seeks to address. The first concerns the role of the robots in biological research: do they simulate something (life, evolution, sociality) or do they participate in something? The second question concerns the physicality of the robots: what difference does embodiment make to the role of the robot in these experiments. Thirdly, how do life, embodiment and social behavior relate in contemporary biology and why is it possible for robots to illuminate this relation? These questions are provoked by a strange similarity that has not been noted before: between the problem of simulation in philosophy of science, and Deleuze's reading of Plato on the relationship of ideas, copies and simulacra

The HY5-PIF regulatory module coordinates light and temperature control of photosynthetic gene transcription

The ability to interpret daily and seasonal alterations in light and temperature signals is essential for plant survival. This is particularly important during seedling establishment when the phytochrome photoreceptors activate photosynthetic pigment production for photoautotrophic growth. Phytochromes accomplish this partly through the suppression of phytochrome interacting factors (PIFs), negative regulators of chlorophyll and carotenoid biosynthesis. While the bZIP transcription factor long hypocotyl 5 (HY5), a potent PIF antagonist, promotes photosynthetic pigment accumulation in response to light. Here we demonstrate that by directly targeting a common promoter cis-element (G-box), HY5 and PIFs form a dynamic activation-suppression transcriptional module responsive to light and temperature cues. This antagonistic regulatory module provides a simple, direct mechanism through which environmental change can redirect transcriptional control of genes required for photosynthesis and photoprotection. In the regulation of photopigment biosynthesis genes, HY5 and PIFs do not operate alone, but with the circadian clock. However, sudden changes in light or temperature conditions can trigger changes in HY5 and PIFs abundance that adjust the expression of common target genes to optimise photosynthetic performance and growth

Legislative Participation in the EU: An analysis of questions, speeches, motions and declarations in the 7th European Parliament

Which legislative activities in the European Parliament are ‘pluralistic’ – i.e. undertaken by all Members of the European Parliament, irrespective of legislative and electoral status? What type of parliamentary activity – if any – is dominated by party leaderships or vote-seekers in the European Union? This study will advance our knowledge of legislative politics in the EU by determining whether its legislature conforms to expectations from the legislative behaviour literature. This study compares the participation patterns in the EP7 (2009–2014) parliamentary questions, speeches, motions and written declarations via multilevel negative binomial regression. It makes use of a dataset on activity levels and demographics of 842 individual Members of the European Parliament serving between 2009 and 2014. The findings highlight that highly procedurally constrained activities, such as speeches and oral questions, are dominated by frontbenchers and vote-seekers, while procedurally ‘freer’ activities – written questions in particular – are very representative of the population of Members of the European Parliament. The analysis finds that there are both ‘pluralistic’ and vote-seeking activities in the ‘second order’ EU legislature, and that participation patterns broadly conform to patterns found in other established representative democracies

Effect of "no added salt diet" on blood pressure control and 24 hour urinary sodium excretion in mild to moderate hypertension

<p>Abstract</p> <p>Background</p> <p>The incidence of Hypertension as a major cardiovascular threat is increasing. The best known diet for hypertensives is 'no added salt diet'.</p> <p>In this study we evaluated the effect of 'no added salt diet' on a hypertensive population with high dietary sodium intake by measuring 24 hour urinary sodium excretion.</p> <p>Methods</p> <p>In this single center randomized study 80 patients (60 cases and 20 controls) not on any drug therapy for hypertension with mild to moderate hypertension were enrolled. 24 hour holter monitoring of BP and 24 hour urinary sodium excretion were measured before and after 6 weeks of 'no added salt diet'.</p> <p>Results</p> <p>There was no statistically significant difference between age, weight, sex, Hyperlipidemia, family history of hypertension, mean systolic and diastolic BP during the day and at night and mean urinary sodium excretion in 24 hour urine of case and control groups. Seventy eight percent of all patients had moderate to high salt intake.</p> <p>After 6 week of 'no added salt diet' systolic and diastolic BP significantly decreased during the day (mean decrease: 12.1/6.8 mmhg) and at night (mean decrease: 11.1/5.9 mmhg) which is statistically significant in comparison to control group (P 0.001 and 0.01).</p> <p>Urinary sodium excretion of 24 hour urine decreased by 37.1 meq/d ± 39,67 mg/dl in case group which is statistically significant in comparison to control group (p: 0.001).</p> <p>Only 36% of the patients, after no added salt diet, reached the pretreatment goal of 24 hour urinary sodium excretion of below 100 meq/dl (P:0.001).</p> <p>Conclusion</p> <p>Despite modest effect on dietary sodium restriction, no added salt diet significantly decreased systolic and diastolic BP and so it should be advised to every hypertensive patient.</p> <p>Trial Registration</p> <p>Clinicaltrial.govnumber NCT00491881</p
