Understanding the impact of painful diabetic neuropathy

DIABETES/METABOLISM: RESEARCH AND REVIEWS, Issue S1 2003
Cristian Quattrini
Abstract Painful neuropathy is a common and often distressing complication of diabetes. It has considerable impact on the social and psychological well-being of affected individuals. There are two distinct forms of painful neuropathy: an acute and self-limiting form that resolves within a year or a chronic form that can go on for years. There are now a number of drugs available for the treatment of neuropathic pain. However, some may fail to respond to these drugs or may have unacceptable adverse side effects. When this is the case, the patient's quality of life can be severely affected. Health care professionals need to assess the full impact of painful neuropathy. In this article we review a number of instruments that are used to assess the severity of painful neuropathy and its impact on the quality of life. Copyright © 2003 John Wiley & Sons, Ltd. [source]


Health-related quality of life assessment in randomised controlled trials in multiple myeloma: a critical review of methodology and impact on treatment recommendations

EUROPEAN JOURNAL OF HAEMATOLOGY, Issue 4 2009
Ann Kristin Kvam
Abstract Objectives:, Patients with multiple myeloma (MM) often have pronounced symptoms and substantially reduced quality of life. The aims of treatment are to control disease, maximise quality of life and prolong survival. Hence, health-related quality of life (HRQOL) should be an important end-point in randomised controlled trials (RCTs) in addition to traditional endpoints. We wanted to evaluate whether trials reporting HRQOL outcomes have influenced clinical decision making and whether HRQOL was assessed robustly according to predefined criteria. Methods:, A systematic review identified RCTs in MM with HRQOL assessment as a study end-point. The methodological quality of these studies was assessed according to a checklist developed for evaluating HRQOL outcomes in clinical trials. The impact of the HRQOL results on clinical decision making was assessed, using published clinical guidelines as a reference. Results:, Fifteen publications presenting RCTs with HRQOL as a study end-point were identified. In 13 trials, the author stated that HRQOL results should influence clinical decision making. We found, however, that the HRQOL data only had a limited impact on published treatment guidelines for bisphosphonates, high-dose treatment, interferon, erythropoiesis-stimulating agents and novel agents. Conclusion:, The present review indicates that the there are still few RCTs in MM including HRQOL as a study end-point. Systematic incorporation of HRQOL measures into clinical trials allows for a comparison of treatment arms that includes the patients' perspective. Before the full impact on clinical decisions can be realised, the quality and methodology of collecting HRQOL data must be further improved and the results rendered more comprehensible to clinicians.

Review paper: more than ringing in the ears: a review of tinnitus and its psychosocial impact

JOURNAL OF CLINICAL NURSING, Issue 21 2009
Susan Holmes
Aim and objectives., To provide an overview of tinnitus, current management and its psychosocial impact offering strategies for managing acute and chronic tinnitus in practice. Background., Tinnitus, characterised by the perception of sound in the absence of external stimuli, is experienced by about 10% of the population at some time in their lives. It may be temporary/longstanding; approximately 5% adults experience severe, persistent tinnitus affecting their lifestyle. Although many adjust successfully, others are disabled by the condition. Though often unrecognised, tinnitus affects many patients regardless of their presenting illness. Design., A literature review including descriptive, theoretical and empirical material. Databases were searched using the keyword ,tinnitus' providing diverse information which was used to address the research questions. Results., Tinnitus represents more than ,simple' ringing in the ears and may be accompanied by many distressing changes. It may be acute or chronic. It is difficult to treat, care may be directed towards management rather than cure. Many patients are, however, told that ,nothing can be done'. Relevance to clinical practice., Despite the high prevalence of tinnitus, there is a paucity of relevant nursing literature suggesting that there is an information deficit amongst nurses. The information provided shows that understanding the full impact of the condition and identification of patients' needs are essential to effective care. Strategies to help affected patients are given. Conclusions., Tinnitus, a widespread, often intractable condition, affects millions of people; there is considerable debate about its causes. Tinnitus is distressing and may be severe enough to affect lifestyle and quality of life. Affected patients need considerable support and advice on healthcare options, encouragement to try different treatments and recognition that help and hope are available. Though patients may have to learn to live with tinnitus, the most important thing is that they recognise that help is available. [source]


A critical analysis of UK public health policies in relation to diet and nutrition in low-income households

MATERNAL & CHILD NUTRITION, Issue 2 2006
Pamela Attree phd
Abstract Diet and nutrition, particularly among low-income groups, is a key public health concern in the UK. Low levels of fruit and vegetable consumption, and obesity, especially among children, have potentially severe consequences for the future health of the nation. From a public health perspective, the UK government's role is to help poorer families make informed choices within healthy frameworks for living. However, the question is , to what extent are such policies in accordance with lay experiences of managing diet and nutrition on a low-income? This paper critically examines contemporary public health policies aimed at improving diet and nutrition, identifying the underlying theories about the influences on healthy eating in poor families, and exploring the extent to which these assumptions are based on experiential accounts. It draws on two qualitative systematic reviews , one prioritizing low-income mothers' accounts of ,managing' in poverty; and the other focusing on children's perspectives. The paper finds some common ground between policies and lay experiences, but also key divergencies. Arguably, the emphasis of public health policy on individual behaviour, coupled with an ethos of empowered consumerism, underplays material limitations on ,healthy eating' for low-income mothers and children. Health policies fail to take into account the full impact of structural influences on food choices, or recognize the social and emotional factors that influence diet and nutrition. In conclusion, it is argued that while health promotion campaigns to improve low-income families' diets do have advantages, these are insufficient to outweigh the negative effects of poverty on nutrition.

Low-income mothers, nutrition and health: a systematic review of qualitative evidence

MATERNAL & CHILD NUTRITION, Issue 4 2005
Pamela Attree phd
Abstract Diet is a key issue for UK health policies, particularly in relation to poorer socio-economic groups. From a public health perspective, the government's role is to help low-income families to make healthy food choices, and to create the conditions to enable them to make healthy decisions. Arguably, however, current policy on nutrition and health is influenced by individualist and behavioural perspectives, which fail to take into account the full impact of structural factors on food choices. This paper draws on a systematic review of qualitative studies that prioritize low-income mothers' accounts of ,managing' in poverty, synthesizing a subset of studies that focus on diet, nutrition and health in poor families. Synthesis findings are explored in the context of dominant discourses concerning individual responsibility for health and gendered societal values concerning ,good' mothering. The paper concludes that a shift in emphasis in health policies, affording a higher priority to enabling measures that tackle the underlying determinants of health, would be advantageous in reducing nutritional inequities for low-income mothers and their children.

,It's magic stuff': The experiences of patients with ankylosing spondylitis taking anti-TNF-, medication

MUSCULOSKELETAL CARE, Issue 3 2009
J. Stockdale MSc MCSP
Abstract Introduction:,Several studies have identified the efficacy of anti-tumour necrosis factor-alpha (anti-TNF-,) treatment in ankylosing spondylitis (AS). However, few studies have explored the perceptions of patients taking this new medication. The aim of this study was to explore the impact of anti-TNF-, on the quality of life of people with AS. Methods:,A qualitative approach was adopted to provide a holistic understanding of participants' views and experiences in the context of their overall lives. Semi-structured interviews were undertaken and transcribed verbatim. Data were analysed using thematic analysis. Ethical approval and informed consent were obtained. Results:,Eight people participated and described a significant improvement in their physical and psychological status, leading to a more positive outlook on their life. Specific areas highlighted were employment, activities of daily living, hobbies and relationships with partners and family, some of which are not captured by current AS-specific outcome measures. Negative aspects of anti-TNF-, use were described as the inconvenience of monitoring and issues relating to travelling abroad. All participants expressed concern about the possibility of being withdrawn from treatment and the perceived impact this would have on their lives. Conclusions:,Anti-TNF-, treatment has a positive impact on the lives of people with AS, such that a major concern is being withdrawn from treatment, highlighting the need to provide tailored support to people being withdrawn from treatment. To capture the full impact of anti-TNF-, treatment, further consideration needs to be given to the choice of appropriate outcome measures. Copyright © 2008 John Wiley & Sons, Ltd. [source]


Oil demand in North America: 1980-2020

OPEC ENERGY REVIEW, Issue 4 2001
Salman Saif Ghouri
This paper first analyses price and income elasticity of oil demand in the United States, Canada and Mexico for the period 1980-99. Economic activity is the main driving force that influences oil consumption in each country. Changes in oil consumption generally lagged by a few years before the full impact of changes in oil prices was realized. Consumers in the short run are constrained by technological and other barriers and, therefore, less sensitive to changes in oil prices; however, they are more responsive in the long run , though response is still inelastic. The use of advanced technology facilitated these countries to use less oil over time. The paper then looks at demand over the next 20 years. The best-fitting model predicts that, by the end of 2020 (reference case), the USA, Canada and Mexico will respectively consume 24,900, 2,596 and 2,321 thousand barrels daily, compared with 19,519, 1,943 and 1,970 thousand b/d in 1999. The model forecasts economic slowdown during 2000/2002. The USA and Canada are expected to recover quickly, while Mexico will take longer. [source]


Microarray analysis of liver gene expression in iron overloaded patients with sickle cell anemia and beta-thalassemia,

AMERICAN JOURNAL OF HEMATOLOGY, Issue 6 2009
Jonathan M. Flanagan
Chronic transfusion therapy is used clinically to supply healthy erythrocytes for patients with sickle cell anemia (SCA) or beta-thalassemia major (TM). Despite the benefits of red blood cell transfusions, chronic transfusions lead to iron accumulation in key tissues such as the heart, liver, and endocrine glands. Transfusion-acquired iron overload is recognized as a cause of morbidity and mortality among patients receiving chronic transfusions. At present, there is little understanding of molecular events that occur during transfusional iron loading and the reasons for the large inter-individual variation observed clinically in transfusion-acquired iron accumulation. To address these issues, we examined whether any liver-expressed genes in SCA or TM patients with transfusional iron overload were associated with the degree of iron accumulation. Specifically, we performed microarray analysis on liver biopsy specimens comparing SCA patients with mild or severe iron overload and also compared SCA with TM patients. Fifteen candidate genes were identified with significantly differential expression between the high and low liver iron concentrations. SCA patients and 20 candidate genes were detected between the SCA and TM patient comparison. Subsequent quantitative PCR experiments validated 12 candidate genes; with GSTM1, eIF5a, SULF2, NTS, and HO-1 being particularly good prospects as genes that might affect the degree of iron accumulation. Future work will determine the baseline expression of these genes prior to transfusional iron overload and elucidate the full impact of these genes on the inter-individual variation observed clinically in transfusion-acquired iron accumulation.

Dimensions of quality of life and psychosocial variables most salient to colorectal cancer patients

PSYCHO-ONCOLOGY, Issue 1 2006
Jeff Dunn
Abstract Colorectal cancer is one of the most common invasive cancers, and is responsible for considerable physical and psychosocial morbidity. Understanding the quality of life experienced by colorectal cancer patients is essential for evaluating the full impact of the disease on individuals, their families and their communities. Patient perspective is essential in establishing a proper understanding of the quality of life of colorectal cancer patients. Despite this, few studies have employed a qualitative methodology to explore quality of life issues for colorectal cancer patients. A review of the literature identified only seven qualitative studies pertaining to quality of life issues for colorectal cancer patients, a surprising finding given the prevalence of this cancer. Accordingly, this study sought to build on the findings of previous qualitative research by providing descriptive data on the quality of life and psychosocial variables most salient to colorectal cancer patients. Six core themes emerged from interview and focus group data: Satisfaction with diagnosis and treatment; support (including information provision); quality of life; benefits of diagnosis; making sense of the cancer experience; and coping strategies. The information derived from this study will help inform the development of supportive care services to address the needs of the increasing number of people diagnosed with colorectal cancer.

The Expanded Criteria Donor Policy: An Evaluation of Program Objectives and Indirect Ramifications

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 7 2006
J. D. Schold
The expanded criteria donor (ECD) policy was formalized in 2002, which defined higher-risk deceased donor kidneys recovered for transplantation. There has not been a comprehensive examination of the impact of policy on the allocation of ECD kidneys, waiting times for transplant, center listing patterns or human leukocyte antigen (HLA) matching. We examined transplant candidates from 1998 to 2004 utilizing a national database. We constructed models to assess alterations in recipient characteristics of ECD kidneys and trends in waiting time and cold ischemia time (CIT) associated with policy. We also evaluated the impact of the proportion of center candidate listings for ECD kidneys on waiting times. Elderly recipients were more likely to receive ECDs following policy (odds ratio = 1.36, p < 0.01). There was no association of decreased CIT or pretransplant dialysis time while increasing HLA mismatching with policy inception. Over one quarter of centers listed <20% of candidates for ECDs, while an additional quarter of centers listed >90%. Only centers with selective listing for ECDs offered reduced waiting times to ECD recipients. The ECD policy demonstrates potential to achieve certain ascribed goals; however, the full impact of the program, reaching all transplant candidates, may only be achieved once ECD listing patterns are recommended and adopted accordingly.
