Patients' perceptions and views of surgery and radioiodine ablation in the definitive management of Graves' disease.

BACKGROUND: Patients' perceptions and preferences influence the choice of radioiodine ablation (RIA) or surgery in the definitive management of Graves' disease. This study aimed to evaluate their concerns, experiences and satisfaction following definitive treatment. METHODS: A postal survey of patients who had treatment with surgery or RIA between January 2011 and June 2013 for Graves' disease was conducted. RESULTS: Of 214 patients, 136 (64%) responded. The majority of patients felt actively involved in decision making (83.8%) and were satisfied (84.9%) with their treatment. Compared with RIA, patients who underwent surgery were more satisfied with their treatment (p=0.008). Discussion with the doctor was the most useful aid to decision making. Feeling involved in decision-making process was associated with improved satisfaction (p<0.001).Common reasons for not choosing surgery were need for general anaesthesia, scarring and voice change. Avoiding close contact, risk of persistent hyperthyroidism and worsening eye disease were common reasons for not choosing RIA. Ongoing concerns were hypothyroidism, scarring and eye problems after surgery and hypothyroidism and eye problems after RIA. CONCLUSIONS: This study provides insight into patients' experiences of surgery and RIA for Graves' disease and reinforces the importance of patient involvement in the decision-making process

Epidemiology, management and outcomes of Graves’ disease—real life data.

PURPOSE: Treatment options in Graves' disease are clearly defined, but management practices and the perceptions of success are varied. The outcomes of treatment in large consecutive cohorts of Graves' disease have not been well characterised. The study describes the epidemiology, management strategies and medium term outcomes following anti-thyroid drug treatment, radio-iodine ablation and surgery in Graves' disease. METHODS: All patients (n = 659) who received treatment for a new diagnosis of Graves' disease in secondary care over a 5 year period were included with a median (interquartile range) follow-up of 42.9 (29-57.5) months. RESULTS: The age adjusted incidence of adult onset Graves' disease in Sheffield, UK was 24.8 per 100,000 per year. Excluding 35 patients lost to follow-up, 93.1% (n = 581) were controlled on anti-thyroid drug treatment. Of these, 73.6% went into remission following withdrawal of anti-thyroid drugs; 5.2% were still undergoing initial therapy; 13.3% lost control whilst on anti-thyroid drugs; and 7.9% went on to have either surgery or radio-iodine ablation whilst controlled on anti-thyroid drugs. Of the 428 patients who achieved remission, 36.7% relapsed. Of 144 patients who had radio-iodine ablation treatment, 5.6% relapsed and needed further treatment. Of 119 patients having surgery, 5.2% had long-term hypoparathyroidism and none had documented long-term recurrent laryngeal nerve palsy. CONCLUSIONS: In the follow-up, 39.9% of patients underwent surgery or radio-iodine ablation with little morbidity. Up to two-thirds of patients who achieved remission did not relapse. Data on effectiveness and risks of treatments for Graves' disease presented in this study will help clinicians and patients in decision making

Beneficial Effects of Berberine on Oxidized LDL-induced Cytotoxicity in Human Retinal Müller Cells

PURPOSE: Limited mechanistic understanding of diabetic retinopathy (DR) has hindered therapeutic advances. Berberine, an isoquinolone alkaloid, has shown favorable effects on glucose and lipid metabolism in animal and human studies, but effects on DR are unknown. We previously demonstrated intraretinal extravasation and modification of LDL in human diabetes, and toxicity of modified LDL to human retinal Müller cells. We now explore pathogenic effects of modified LDL on Müller cells, and the efficacy of berberine in mitigating this cytotoxicity. METHODS: Confluent human Müller cells were exposed to in vitro–modified ‘highly oxidized, glycated (HOG-) LDL versus native-LDL (N-LDL; 200 mg protein/L) for 6 or 24 hours, with/without pretreatment with berberine (5 μM, 1 hour) and/or the adenosine monophosphate (AMP)-activated protein kinase (AMPK) inhibitor, Compound C (5 μM, 1 hour). Using techniques including Western blots, reactive oxygen species (ROS) detection assay, and quantitative real-time PCR, the following outcomes were assessed: cell viability (CCK-8 assay), autophagy (LC3, Beclin-1, ATG-5), apoptosis (cleaved caspase 3, cleaved poly-ADP ribose polymerase), oxidative stress (ROS, nuclear factor erythroid 2-related factor 2, glutathione peroxidase 1, NADPH oxidase 4), angiogenesis (VEGF, pigment epithelium-derived factor), inflammation (inducible nitric oxide synthase, intercellular adhesion molecule 1, IL-6, IL-8, TNF-α), and glial cell activation (glial fibrillary acidic protein). RESULTS: Native-LDL had no effect on cultured human Müller cells, but HOG-LDL exhibited marked toxicity, significantly decreasing viability and inducing autophagy, apoptosis, oxidative stress, expression of angiogenic factors, inflammation, and glial cell activation. Berberine attenuated all the effects of HOG-LDL (all P < 0.05), and its effects were mitigated by AMPK inhibition (P < 0.05). CONCLUSIONS: Berberine inhibits modified LDL-induced Müller cell injury by activating the AMPK pathway, and merits further study as an agent for preventing and/or treating DR

Lives are led: autobiographical film and the new documentary

This thesis consists of two parts: an autobiographical documentary film and a written exegesis. The film, My Lovers Both, is a record of two journeys back to my native South Africa wherein I confront aspects of my past. These two trips offer a means to explore a personal history around the experiences of immigration, displacement and exile. In the exegesis, I argue that autobiography is changing and rather than offering catalogues of public achievement, contemporary personal histories deal with sites of trauma and challenge dominant narratives of official memory. Likewise, the New Documentary is embracing fictional strategies and moving towards increased subjectivity and introspection. As a consequence, new forms are created that generate novel insights into causality and time. The exegesis goes on to examine the major influences on my work as a filmmaker and then articulates a reflective analysis of the creative process which produced My Lovers Both

Hypoxia-induced responses by endothelial colony-forming cells are modulated by placental growth factor

BACKGROUND: Endothelial colony-forming cells (ECFCs), also termed late outgrowth endothelial cells, are a well-defined circulating endothelial progenitor cell type with an established role in vascular repair. ECFCs have clear potential for cell therapy to treat ischaemic disease, although the precise mechanism(s) underlying their response to hypoxia remains ill-defined. METHODS: In this study, we isolated ECFCs from umbilical cord blood and cultured them on collagen. We defined the response of ECFCs to 1% O(2) exposure at acute and chronic time points. RESULTS: In response to low oxygen, changes in ECFC cell shape, proliferation, size and cytoskeleton phenotype were detected. An increase in the number of senescent ECFCs also occurred as a result of long-term culture in 1% O(2). Low oxygen exposure altered ECFC migration and tube formation in Matrigel®. Increases in angiogenic factors secreted from ECFCs exposed to hypoxia were also detected, in particular, after treatment with placental growth factor (PlGF). Exposure of cells to agents that stabilise hypoxia-inducible factors such as dimethyloxalylglycine (DMOG) also increased PlGF levels. Conditioned medium from both hypoxia-treated and DMOG-treated cells inhibited ECFC tube formation. This effect was reversed by the addition of PlGF neutralising antibody to the conditioned medium, confirming the direct role of PlGF in this effect. CONCLUSIONS: This study deepens our understanding of the response of ECFCs to hypoxia and also identifies a novel and important role for PlGF in regulating the vasculogenic potential of ECFCs.

The grinch who stole wisdom

Dr. Seuss is wise. How the Grinch Stole Christmas (Seuss, 1957) could serve as a parable for our time. It can also be seen as a roadmap for the development of contemplative wisdom. The abiding popularity of How the Grinch Stole Christmas additionally suggests that contemplative wisdom is more readily available to ordinary people, even children, than is normally thought. This matters because from the point of view of contemplatives in any of the world's philosophies or religions, people are confused about wisdom. The content of the nascent field of wisdom studies, they might say, is largely not wisdom at all but rather what it's like to live in a particular kind of prison cell, a well appointed cell perhaps, but not a place that makes possible either personal satisfaction or deep problem solving. I believe that what the contemplative traditions have to say is important; they offer a different orientation to what personal wisdom is, how to develop it, and how to use it in the world than is presently contained in either our popular culture or our sciences. In order to illustrate this I will examine, in some detail, one contemplative path within Buddhism. Buddhism is particularly useful in this respect because its practices are nontheistic and thus avoid many of the cultural landmines associated with the contemplative aspects of Western religions

Relative communicators: evaluation of an innovative hospital role emerging from the Covid-19 pandemic

Background: During the COVID-19 pandemic, hospital visiting policies made communication challenging. Effective communication is known to reduce anxiety for patients and relatives, and improve trust in healthcare services. We describe an innovative project in which students and staff were deployed to the role of ‘Relative Communicators’, enabling routine updates and facilitating video calls between patients and their next of kin (NOK). The aim of our project was to explore NOK's perceptions of communication about their inpatient relatives and the Relative Communicators. // Method: Participants were asked to complete a structured interview over a telephone call but could use the online form if this was not possible. Hence, we obtained data using a combination of interviews and online surveys. NOK, who utilized the relative communicator service (n = 30), were surveyed. Quantitative data and free-text responses were analysed to understand their perceptions. // Results: 85.7% of respondents (24/28) were satisfied with information they received from Relative Communicators. 43.3% (13/30) of NOK felt they could communicate with their relative ‘the right amount’, and 56.7% (17/30) felt they were sufficiently involved in care decisions. Qualitative data provided further insights around the demand for proactive updates, frustration with existing communication models, and praise of telecommunication methods. // Conclusions: We suggest proactive updates and telecommunication could improve the experience for patients and NOK. Relative Communicators provided a bridge for inpatients and NOK to connect. The pandemic has exacerbated systemic communication issues and innovations, such as the Relative Communicators, may help to address these challenges

‘Paying Attention’ in a Digital Economy: Reflections on the Role of Analysis and Judgement Within Contemporary Discourses of Mindfulness and Comparisons with Classical Buddhist Accounts of Sati

This chapter examines the question of the role of intellectual analysis and ethical judgement in ancient Indian Buddhist accounts of sati and contemporary discourses about ‘mindfulness’. Attention is paid to the role of paññ? (Sanskrit: prajñ?: ‘wisdom’ or ‘analytical insight’) and ethical reflection in the cultivation of sati in mainstream Abhidharma and early Mah?y?na philosophical discussions in India, noting the existence of a subordinate strand of Buddhist thought which focuses upon the non-conceptuality of final awakening (bodhi) and the quiescence of mind. Modern discourses of mindfulness are examined in relation to detraditionalization, the global spread of capitalism and widespread adoption of new information technologies. It is argued that analysis of the exponential growth in popularity of ‘mindfulness’ techniques must be linked to an exploration of the modern history of attention, more specifically, the possibility that the use of fast-paced, digital, multimedia technologies is facilitating a demand for fragmented or dispersed attention. It is argued that the fault line between divergent contemporary accounts of mindfulness can be seen most clearly over the issue of the role of ethical judgements and mental ratiocination within mindfulness practice. The two most extreme versions on this spectrum see mindfulness on the one hand as a secular mental technology for calming the mind and reducing stress and discomfort, and on the other as a deeply ethical and experiential realization of the geopolitics of human experience. These, it is suggested, constitute an emerging discursive split in accounts of mindfulness reflective of divergent responses to the social, economic, political and technological changes occurring in relation to the global spread of neoliberal forms of capitalism
