5. Vital Signs: Awareness and Treatment of Uncontrolled Hypertension Among Adults -- United States, 2003-2010
By Valderrama, Amy L.; Gillespie, Cathleen; King, Sallyann Coleman; George, Mary G.; Hong, Yuling; Gregg, Edward. MMWR: Morbidity & Mortality Weekly Report. 9/7/2012
Abstract:
  Hypertension is a leading risk factor for cardiovascular disease and a significant cause of morbidity and mortality. This report uses data from the National Health and Nutrition Examination Survey (NHANES) to examine awareness and pharmacologic treatment of uncontrolled hypertension among U.S. adults with hypertension and focuses on three groups: those who are unaware of their hypertension, those who are aware but not treated with medication, and those who are aware and pharmacologically treated with medication but still have uncontrolled hypertension.
Methods: CDC analyzed data from the NHANES 2003-2010 to estimate the prevalence of hypertension awareness and treatment among adults with uncontrolled hypertension. Hypertension was defined as an average systolic blood pressure (SBP) =140 mmHg or an average diastolic blood pressure (DBP) =90 mmHg, or currently using blood pressure (BP)-lowering medication. Uncontrolled hypertension was defined as an average SBP =140 mmHg or an average DBP =90 mmHg, among those with hypertension.
Results: The overall prevalence of hypertension among U.S. adults aged =18 years in 2003-2010 was 30.4% or an estimated 66.9 million. Among those with hypertension, an estimated 35.8 million (53.5%) did not have their hypertension controlled. Among these, an estimated 14.1 million (39.4%) were not aware of their hypertension, an estimated 5.7 million (15.8%) were aware of their hypertension but were not receiving pharmacologic treatment, and an estimated 16.0 million (44.8%) were aware of their hypertension and were being treated with medication. Of the 35.8 million U.S. adults with uncontrolled hypertension, 89.4% reported having a usual source of health care, and 85.2% reported having health insurance.
Implications for Public Health Practice: Nearly 90% of U.S. adults with uncontrolled hypertension have a usual source of health care and insurance, representing a missed opportunity for hypertension control. Improved hypertension control will require an expanded effort and an increased focus on BP from health-care systems, clinicians, and individuals. [ABSTRACT FROM AUTHOR].

8. A new epoprostenol formulation for the treatment of pulmonary arterial hypertension
By Fuentes, Amaris; Coralic, Aida; Dawson, Kyle L. American Journal of Health-System Pharmacy. 8/15/2012, Vol. 69 Issue 16: p1389-1393
Abstract:
 The pharmacology and pharmacokinetics of a novel formulation of epoprostenol for the treatment of pulmonary arterial hypertension (PAH) are reviewed, with guidance on addressing a number of important safety considerations.
Summary. Epoprostenol is a direct vasodilator of the pulmonary and systemic vasculature indicated for improving exercise capacity in patients with PAH. Veletri, a recently approved formulation of epoprostenol for continuous i.v. infusion, offers increased stability relative to other available epoprostenol products. Therefore, the use of Veletri can lessen the therapy burden associated with the other available formulation of the drug by allowing for the advance preparation of infusion pump cassettes (at certain concentrations) and administration at room temperature without the need for cooling with ice packs. Sterility, however, is of concern with outpatient preparation of epoprostenol-containing cassettes stored for the maximum duration according to stability guidelines. All epoprostenol infusions are classified as high-risk therapies due to complex dosing, the drug's short half-life, and the potential for life-threatening rebound PAH with abrupt discontinuation. Adverse effects reported in =10% of participants in clinical trials of Veletri included flushing (58%), headache (49%), nausea or vomiting (32%), hypotension (16%), chest pain (11%), and anxiety, nervousness, or agitation (11%). As with other epoprostenol formulations, the use of Veletri requires an evaluation of health-system medication-use practices to ensure patient safety.
Conclusion. Veletri provides an epoprostenol therapy option that reduces some of the inconveniences of the other formulation. Drug stability is dependent on cassette concentrations, which may be limited by sterility concerns with outpatient preparation. Use of this new agent within the health system requires an evaluation of practices to ensure patient safety. [ABSTRACT FROM AUTHOR].

9. Effects of dark chocolate on blood pressure in patients with hypertension
By Haber, Stacy L.; Gallus, Karen. American Journal of Health-System Pharmacy. 8/1/2012, Vol. 69 Issue 15: p1287-1293
Abstract
: The article presents an overview of the different clinical trials that have been conducted to determine the impacts of dark chocolate on blood pressure in patients suffering from hypertension. The study conducted by Taubert and colleagues in 2003 for around thirteen patients proved that dark chocolate favorably affect blood pressure in hypertension patients. However, additional factors need to be considered in further studies for better results..

10. Questioning context: a set of interdisciplinary questions for investigating contextual factors affecting health decision making
By Charise, Andrea; Witteman, Holly; Whyte, Sarah; Sutton, Erica J.; Bender, Jacqueline L.; Massimi, Michael; Stephens, Lindsay; Evans, Joshua; Logie, Carmen; Mirza, Raza M.; Elf, Marie. Health Expectations. Jun 2011, Vol. 14 Issue 2, p115-132
Abstract
: To combine insights from multiple disciplines into a set of questions that can be used to investigate contextual factors affecting health decision making. Decision-making processes and outcomes may be shaped by a range of non-medical or 'contextual' factors particular to an individual including social, economic, political, geographical and institutional conditions. Research concerning contextual factors occurs across many disciplines and theoretical domains, but few conceptual tools have attempted to integrate and translate this wide-ranging research for health decision-making purposes. To formulate this tool we employed an iterative, collaborative process of scenario development and question generation. Five hypothetical health decision-making scenarios (preventative, screening, curative, supportive and palliative) were developed and used to generate a set of exploratory questions that aim to highlight potential contextual factors across a range of health decisions. We present an exploratory tool consisting of questions organized into four thematic domains - Bodies, Technologies, Place and Work (BTPW) - articulating wide-ranging contextual factors relevant to health decision making. The BTPW tool encompasses health-related scholarship and research from a range of disciplines pertinent to health decision making, and identifies concrete points of intersection between its four thematic domains. Examples of the practical application of the questions are also provided. These exploratory questions provide an interdisciplinary toolkit for identifying the complex contextual factors affecting decision making. The set of questions comprised by the BTPW tool may be applied wholly or partially in the context of clinical practice, policy development and health-related research. [ABSTRACT FROM AUTHOR].

11. Clinicians' concerns about decision support interventions for patients facing breast cancer surgery options: understanding the challenge of implementing shared decision-making.
By Caldon, Lisa J.M.; Collins, Karen A.; Reed, Malcolm W.; Sivell, Stephanie; Austoker, Joan; Clements, Alison M.; Patnick, Julietta; Elwyn, Glyn. Health Expectations. Jun 2011, Vol. 14 Issue 2: p133-146
Abstract:
There is interest in interventions that provide support for patients facing challenging decisions, such as the choice between mastectomy and breast conservation surgery for breast cancer. However, it is difficult to implement these interventions. One potential source of resistance is the attitudes of clinicians. To examine specialist breast clinicians' opinions about the provision of decision support interventions (DesIs) for patients. As part of the development of a web-based DesI (BresDex), semi-structured interviews were conducted with specialist clinicians [breast surgeons, breast care nurses (BCNs) and oncologists] from four breast units in a UK region, and speciality national opinion leaders. Interviews were recorded, transcribed and analysed using the Framework approach. A majority of the 24 clinicians interviewed did not have a working knowledge of DesIs and were ambivalent or sceptical. Many expressed conflicting opinions: they noted the potential benefits, but at the same time expressed reservations about information overlap, overload and about content that they considered inappropriate. Many wanted access to DesIs to be always under clinical supervision. In particular, they were uncertain as regards how DeSIs could be tailored to individual patients' needs and also accommodate clinical practice variation. BCNs were particularly concerned that DesIs might induce patient anxiety and replace their role. The concept of providing interventions to support patients in decision-making tasks generated concern, defensiveness and scepticism. These attitudes will be a significant barrier. Implementation efforts will need to recognize and address these issues if these interventions are to become embedded in clinical practice. [ABSTRACT FROM AUTHOR].

12. Dying cancer patients talk about physician and patient roles in DNR decision making
By Eliott, Jaklin A.; Olver, Ian. Health Expectations. Jun 2011, Vol. 14 Issue 2: p147-158
Abstract:
Within medical and bioethical discourse, there are many models depicting the relationships between, and roles of, physician and patient in medical decision making. Contestation similarly exists over the roles of physician and patient with regard to the decision not to provide cardiopulmonary resuscitation (CPR) following cardiac arrest [the do-not-resuscitate or do-not-resuscitate (DNR) decision], but there is little analysis of patient perspectives. Analyse what patients with cancer within weeks before dying say about the decision to forego CPR and the roles of patient and physician in this decision. Discursive analysis of qualitative data gathered during semi-structured interviews with 28 adult cancer patients close to death and attending palliative or oncology clinics of an Australian teaching hospital. Participants' descriptions of appropriate patient or physician roles in decisions about CPR appeared related to how they conceptualized the decision: as a personal or a medical issue, with patient and doctor respectively identified as appropriate decision makers; or alternatively, both medical and personal, with various roles assigned embodying different versions of a shared decision-making process. Participants' endorsement of physicians as decision makers rested upon physicians' enactment of the rational, knowledgeable and compassionate expert, which legitimized entrusting them to make the DNR decision. Where this was called into question, physicians were positioned as inappropriate decision makers. When patients' and physicians' understandings of the best decision, or of the preferred role of either party, diverge, conflict may ensue. In order to elicit and negotiate with patient preferences, flexibility is required during clinical interactions about decision making. [ABSTRACT FROM AUTHOR].

13. Service user involvement in cancer care: the impact on service users
By Cotterell, Phil; Harlow, Gwen; Morris, Carolyn; Beresford, Peter; Hanley, Bec; Sargeant, Anita; Sitzia, John; Staley, Kristina. Health Expectations. Jun 2011, Vol. 14 Issue 2, p159-169
Abstract:
Service user involvement is embedded in the United Kingdom's National Health Service, but knowledge about the impact of involvement on service users, such as the benefits and challenges of involvement, is scant. Our research addresses this gap. To explore the personal impact of involvement on the lives of service users affected by cancer. We conducted eight focus groups with user groups supplemented by nine face-to-face interviews with involved individuals active at a local, regional and national level. Thematic analysis was conducted both independently and collectively. Sixty-four participants, engaged in involvement activities in cancer services, palliative care and research, were recruited across Great Britain. We identified three main themes: (i) 'Expectations and motivations for involvement'- the desire to improve services and the need for user groups to have a clear purpose, (ii) 'Positive aspects of involvement'- support provided by user groups and assistance to live well with cancer and (iii) 'Challenging aspects of involvement'- insensitivities and undervaluing of involvement by staff. This study identified that involvement has the capacity to produce varied and significant personal impacts for involved people. Involvement can be planned and implemented in ways that increase these impacts and that mediates challenges for those involved. Key aspects to increase positive impact for service users include the value service providers attach to involvement activities, the centrality with which involvement is embedded in providers' activities, and the capacity of involvement to influence policy, planning, service delivery, research and/or practice.

14. How sharp can a screening tool be? A qualitative study of patients' experience of completing a bowel cancer screening questionnaire
By Pugh, Wendy; Porter, Alison M. Health Expectations. Jun 2011, Vol. 14 Issue 2, p170-177
Abstract:
There is evidence to suggest that the Patient Consultation Questionnaire (PCQ) is a reliable tool to predict symptomatic left-sided colorectal cancer. While previous research has examined the sensitivity and specificity of the PCQ as a tool, it has not addressed patients' perspectives. To examine qualitatively patients' perspectives on ease of use of the PCQ, and their attitude to completing it. The target population were patients in North Wales between 55 and 85 years with colorectal symptoms who had completed the PCQ. A sample of six was randomly selected. The approach was qualitative, using semi-structured, in-depth cognitive interviews, which were recorded and transcribed before content and thematic analysis. The study found some areas of concern in relation to the PCQ's design and presentation, concerning such issues as the use of medical jargon or ambiguous wording, and the use of questions to which patients may not have an answer. It also found that patients responded to the form as something more than a screening tool, treating it variously as way of speeding up diagnosis and treatment, an opportunity to 'play the system', and a way of bypassing embarrassing encounters. Although major problems were not identified, the minor issues observed in the PCQ's design and presentation may reduce accuracy and patient satisfaction. A greater understanding of patients' perception of the role and function of the PCQ may help clinicians to interpret responses to the form more accurately. [ABSTRACT FROM AUTHOR].

16. A relational perspective on autonomy for older adults residing in nursing homes
By Sherwin, Susan; Winsby, Meghan. Health Expectations. Jun 2011, Vol. 14 Issue 2: p182-190
Abstract
: To review critically the traditional concept of autonomy, propose an alternative relational interpretation of autonomy, and discuss how this would operate in identifying and addressing ethical issues that arise in the context of nursing home care for older adults. Respect for patient autonomy has been the cornerstone of clinical bioethics for several decades. Important though this principle is, there is debate on how to interpret the core concept of autonomy. We review the appeal of the traditional approach to autonomy in health care and then identify some of the difficulties with this conception. We use philosophical methods to explain and discuss the traditional and relational conceptions of autonomy and we illuminate our discussion with examples of various contextual applications. We support the relational conception of autonomy as offering a richer, more contextualized understanding of autonomy which attends to the social, political and economic conditions that serve as background to an agent's deliberations. To illuminate these ideas, we discuss the situation of frail older adults who frequently find their autonomy limited not only by their medical conditions but also by cultural prejudices against the aged and by the conditions commonly found within the nursing homes in which many reside. We propose ways of improving the relational autonomy of this population. [ABSTRACT FROM AUTHOR].

20. Severe obesity still growing problem for Americans
TVNZ - Friday October 19, 2012

The number of US residents who are severely obese shot up by 70% in the past decade or so, though the increase has slowed in more recent years, according to a US study. Between 2000 and 2010, the proportion of US residents who were severely obese - at least 45kg overweight - rose from 4% to almost 7%, said researchers, whose findings appeared in the International Journal of Obesity
