An fMRI study of Joint Attention Experience

Although much is now known about eye movement detection, little is known about the higher cognitive processes involved in joint attention. We developed video stimuli which when watched, engender an experience of joint attention in the observer. This allowed us to compare an experience of joint attention to nonjoint attention within an fMRI scanning environment. Joint attention was associated with activity in the ventromedial frontal cortex, the left superior frontal gyrus (BA10), cingulate cortex, and caudate nuclei. The ventromedial frontal cortex has been consistently shown to be activated during mental state attribution tasks. BA10 may serve a cognitive integration function, which in this case seems to utilize a perception–action matching process. The activation we identified in BA10 overlaps with a location of increased grey matter density that we recently found to be associated with autistic spectrum disorder. This study therefore constitutes evidence that the neural substrate of joint attention also serves a mentalizing function. The developmental failure of this substrate in the left anterior frontal lobe may be important in the etiology of autistic spectrum disorder.

The experience of cancer cachexia: A qualitative study of advanced cancer patients and their family members

Background
Cachexia in advanced malignancy is a debilitating syndrome which contributes to approximately two million deaths worldwide annually. In spite of advances in understanding the biomedical aspects of cancer cachexia, little attention has been paid to exploring its holistic impact on patients and those who care for them.

Objective
The aim of this paper is to describe the lived experience of cachexia from the perspective of patients with cancer and their family members.

Design
An interpretative phenomenological approach was employed.

Setting and participants
A purposive sampling strategy recruited 15 patients and 12 family members from the Regional Cancer Centre in Northern Ireland.

Method
Each participant was interviewed during 2004/2005 using an unstructured interview. All interviews were recorded and transcribed verbatim. Analysis combined a two stage approach using thematic and interpretative phenomenological analysis.

Results
Analysis generated six superordinate themes that reflected the complex dynamics of the cachexia experience. Themes were: physiological changes in appetite; visuality of cachexia; weight loss interpreted as a bad sign; response from health care professionals; conflict over food; and coping responses.

Conclusions
Findings confirmed that cancer cachexia has far reaching implications for patients and their families, extending beyond physical problems into psychological, social and emotional issues. This insight is a critical first step in the development of more responsive care for these clients.

An exploration of the experience of cancer cachexia: What patients and their families want from health care professionals

The aim of this paper is to investigate the perceptions of patients and family members with regard to care received for cancer cachexia. A qualitative study recruited 27 participants, of which 15 were patients with advanced cancer who had primary cachexia and 12 were family members. Participants were recruited from a regional cancer centre in the UK. All participants took part in a domiciliary interview, which was transcribed verbatim for analysis. A major finding from analysis was ‘lack of response from health care professionals’ in relation to cancer cachexia management. This finding illuminated that patients and their family members wanted three things from healthcare professionals. They wanted their profound weight loss acknowledged, they wanted information about it and why it was happening and they wanted interventions to deal with it. This paper provides powerful messages for healthcare professionals and highlights the needs of patients and their family regarding cancer cachexia management. Patients and their families want this problem addressed by healthcare professionals. This client group requires supportive healthcare interventions, so that they can understand the nature and impact of this syndrome.

Expression of the counter-regulatory peptide intermedin is augmented in the presence of oxidative stress in hypertrophied cardiomyocytes.

Background: Intermedin (IMD), a novel cardiac peptide related to adrenomedullin (AM), protects against myocardial ischemia-reperfusion injury and attenuates ventricular remodelling. IMD’s actions are mediated by a calcitonin receptor-like receptor in association with receptor activity modifying proteins (RAMPs 1-3). Aim/method: using the spontaneously hypertensive rat (SHR) and normotensive Wistar Kyoto (WKY) rat at 20 weeks of age, to examine (i) the presence of myocardial oxidative stress and concentric hypertrophy; (ii) expression of IMD, AM and receptor components. Results: In left and right ventricular cardiomyocytes from SHR vs. WKY cell width (26% left, 15% right) and mRNA expression of hypertrophic markers ANP (2.7 fold left, 2.7 fold right) and BNP (2.2 fold left, 2.0 fold right) were enhanced. In left ventricular cardiomyocytes only (i) oxidative stress was indicated by increased membrane protein carbonyl content (71%) and augmented production of O2- anion (64%); (ii) IMD (6.8 fold), RAMP1 (2.5 fold) and RAMP3 (2.0 fold) mRNA was increased while AM and RAMP2 mRNA was not altered; (iii) abundance of RAMP1 (by 48%), RAMP2 (by 41%) and RAMP3 (by 90%) monomers in cell membranes was decreased. Conclusion: robust augmentation of IMD expression in hypertrophied left ventricular cardiomyocytes indicates a prominent role for this counter-regulatory peptide in the adaptation of the SHR myocardium to the stresses imposed by chronic hypertension. The local concentration and action of IMD may be further enhanced by down-regulation of NEP within the left ventricle.

Postcolonial Culture on Dependent Islands

This article first considers the significance of historical experience in academic studies, including postcolonial studies, concluding with Jane M. Jacobs that “the structures of power that gave rise to empire live on in a more disorganised fashion.” They live on in an organized way, too, in that many islands remain in a colonial relationship, being simultaneously colonial and postcolonial, although having tended “to slip the net of postcolonial theorising.” The article attempts to help fill this gap, especially through consideration of Brian Rourke’s ideas on cultural imposition applied to dependent islands and through investigation of why some islands have not progressed to independence. Case study detail is presented, especially for Bermuda and the Falkland Islands.
