The poverty reduction strategy paper (PRSP) approach has taken centre stage in development asssistance over the past five years. International endorsement of the approach has led to important gains in government focus on poverty reduction, civil society participation and donor behaviour. Yet PRSPs also potentially offer a much greater contribution to aid effectiveness, good governance and poverty reduction in developing countries. With a second generation of PRSPs now set to appear, this article examines the technical and political challenges that need addressing to realise their potential over time. Emerging issues include how to respond to political transitions, alternative design approaches, how to assess financing needs, and ways of enhancing the predictability of aid. [ABSTRACT FROM AUTHOR]

In this study, we investigated whether a type of retroviral interference might be one mechanism that mediates the powerful protection induced by live attenuated SIVC8. Our results show that retroviral interference could be demonstrated between SIV and SHIV-HXBc2 in human T-cell lines chronically infected with either SIVC8 or SIVJ5. Lymphocytes from macaques infected with live attenuated SIVC8 were significantly less sensitive (P < 0.05) to in vitro infection by virulent SIVJ5 and SHIV-HXBc2 than were lymphocytes from naïve controls. However, this significant difference in the sensitivity of lymphocytes to virus infection was not observed for more efficiently replicating viruses such as SHIV[SUBSF33] and SIVsm3. Virus growth was significantly enhanced (P < 0.01) by depletion of CD8+ T-cell, suggesting a role for these cells in the control of SIV replication, both in vitro and in vivo. We found that levels of the β-chemokines regulated upon activation, normal T-cell expressed and secreted, macrophage inflammatory protein-1α and macrophage inflammatory protein-1β did not correlate with inhibition of virus replication. Taken together, our findings do not support the hypothesis that retroviral interference is the mechanism by which live attenuated SIVC8 induces protection. [ABSTRACT FROM AUTHOR]

Background Consultation skills are vitally important in general practice (GP), and now form part of the summative assessment of GP registrars in the UK. GP trainers need to be skilled in teaching consultation skills, and also need the time and resources to ensure that their registrars are competent in consultation skills. Aims To describe the teaching methods used by GP trainers in one deanery, the frequency of teaching of consultation skills, the problems encountered and the training that GP trainers have themselves received both in consultation skills and how to teach them. Method Postal questionnaire survey of all the 164 trainers in the Yorkshire Deanery. Results Replies were received from 129 trainers (response rate 79%) of which 123 could be analysed. Of these trainers, 45 (37%) trainers taught consultation skills fewer than five times a year, 45 (37%) five to 10 times, and 14 (11%) more than 10 times a year. A total of 24 trainers reported problems with teaching consultation skills, most commonly lack of time, technical difficulties, and unreceptive registrars, and 97 (79%) trainers had had some postgraduate training in consultation skills with 112 (91%) reporting some form of teacher training. Conclusion There is considerable variation in the reported frequency of teaching consultation skills, the models used, and the preparation of trainers for teaching, despite a systematic approach to teacher training in the Yorkshire Deanery.

Background: Fontan surgery, a palliative procedure for single ventricle patients, often leads to the need for permanent pacing. Epicardial pacing has limitations, while transvenous pacing carries risks in the Fontan circulation. This case series introduces a novel approach of leadless pacemaker implantation in the extra‐cardiac Fontan (ECF) cohort to overcome these limitations. Methods: The study includes four cases of leadless pacemaker (Micra™) implantation in patients with ECF. Procedures were performed under general anesthesia with guidance from trans‐esophageal echocardiography. Various access routes were used, including trans‐carotid and trans‐fenestration approaches. Procedural details, parameters, and follow‐up data were collected. Results: All leadless pacemaker implantations were successful, with satisfactory electrical parameters and stable pacing postprocedural outcomes during short‐term follow‐up. One patient required closure of their fenestration for symptomatic desaturation post procedurally. Conclusions: Leadless pacemaker implantation via trans‐carotid and trans‐fenestration approaches appears to be a feasible back up option for pacing in Fontan patients where other options have been exhausted or there is a patient choice to avoid surgery. These techniques provide an option to avoid leaded systems or epicardial pacing, reducing the need for multiple thoracotomies and addressing challenges associated with surgical pacing leads. Further studies are needed to evaluate long‐term outcomes and assess the broader application of leadless pacemakers in the Fontan population. [ABSTRACT FROM AUTHOR]

Two experiments find that support for civil commitment procedures for sexually violent predators is based primarily upon the retributive rather than incapacitative goals of respondents. Two discrete samples composed of students (N = 175) and jury-eligible citizens (N = 200) completed experimental surveys assessing their support or opposition to scenarios in which a sexual predator was to be released after completing his criminal sentence. Respondents were sensitive to likelihood of recidivism only when the initial sentence was sufficiently punitive. When initial sentence was lenient, respondents strongly supported civil commitment without regard to future risk. Results are discussed in light of the U.S. Supreme Court's ruling in Kansas v. Hendricks (1997) on the constitutionality of civil commitment laws for sexually violent predators. Copyright © 2007 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Background: Alzheimer's disease (AD) is recognized as one of the greatest global public health challenges. There is increasing consensus that optimal disease modification using pharmaceuticals may best be achieved earlier in the disease continuum before symptoms occur. However, more needs to be understood about what outcomes are meaningful to potential participants in clinical trials within this preventative paradigm and how people make trade‐offs between risks and benefits. The Electronic Person‐Specific Outcome Measure (ePSOM) programme is developing an app to capture person‐specific outcomes and preferences in clinical trials. Objective: As one phase in the ePSOM programme, this study explored what matters when developing new treatments to prevent AD and how trade‐offs are made between risks and benefits, from three perspectives. Design: Focus groups were conducted with people living with memory problems (n = 21) and healthy volunteers (n = 10), and telephone interviews with health and social care professionals (n = 10). Differences and overlap between the three groups were explored. Results: Outcomes that matter lie in five key domains in relation to what matters in everyday life: Everyday Functioning; Relationships and Social Connections; Enjoying Life; Sense of Identity; and Alleviating  Symptoms. Insights were gained into the significance of reducing the risk of developing dementia with drugs and the processes of weighing up risks versus benefits. Discussion and conclusions: The key domains identified are being used to inform the next stage of the ePSOM programme which is to develop a survey to be distributed nationally in the UK to explore these issues further.

Introduction Radiotherapy ( RT) is an essential and cost-effective cancer treatment. It is underutilised in Australia. Bridging the gap between actual and optimal RT utilisation requires not only provision of adequate RT infrastructure but also an understanding of the factors that influence the extent to which this opportunity for RT is utilised. This study explored factors perceived to affect RT-related decision making by consumers and health professionals ( HPs). Methods Six semi-structured focus groups ( FGs) and 13 interviews were conducted at three geographical locations in NSW, Australia ( n = 26 consumers and 30 HPs). Audio recordings of FGs and interviews were transcribed verbatim and analysed thematically. Results An exhaustive list of issues perceived to affect consumer and HP RT decisions was identified. There were common themes across participant groups and locations. Perceptions of RT and its benefits, as well as accurate communication of the expected benefits and risks of RT, were highlighted as important to decision making. Perceived factors relating to 'inconvenience' of RT were multifaceted and included travel, relocation, accommodation, time away from work and financial challenges. Perceived potential barriers to RT referral included knowledge of RT and RT services, availability of a local or visiting RT service, referrer bias, and the low profile of RT. Conclusions Important drivers during RT decisions appear to include the perceived benefit, risks and inconvenience of RT. Underutilisation of RT may also result from multiple barriers at the referrer level. Further research into whether these factors influence actual RT decisions is needed. [ABSTRACT FROM AUTHOR]

The article focuses on the findings of a survey on the perception of health professionals and consumers on involving breast cancer patients in the multidisciplinary discussion (MD) of their disease and treatment plan in Australia. The survey found that the majority of the respondents support shared decision-making. It cites that the common reasons for advocating patient involvement included providing patients with more information and an opportunity to ask questions. Patient advocates support the inclusion of women in the MD meeting.

Background: Ductal carcinoma in situ (DCIS) is a significant issue in Australia and New Zealand with rising incidence because of the implementation of mammographic screening. Current information on its natural history is unable to accurately predict progression to invasive cancer. In 2003, the National Breast Cancer Centre in Australia published recommendations for DCIS. In Australia and New Zealand, the National Breast Cancer Audit collects information on DCIS cases. This article will examine these recommendations and provide information from the audit on current DCIS management. Methods: Three thousand six hundred and twenty-nine cases of DCIS were entered by 274 breast surgeons between January 1998 and December 2004. Data items in the National Breast Cancer Audit database that were covered in the National Breast Cancer Centre recommendations were reviewed. Information was available on the following: diagnostic biopsy rates for all cases and mammographically positive cases and rates of breast conserving surgery (BCS), clear margins following BCS, postoperative radiotherapy following BCS for groups at high risk of recurrence as well as axillary procedures and tamoxifen prescription. Results: Close adherence was found in diagnostic biopsy, BCS and clear margin rates. Some high-risk groups received radiotherapy, although women with ‘close’ margins did not in 33% of cases. Axillary procedures were conducted in 23% of cases and most (81%) patients were not prescribed tamoxifen. Conclusion: There was predominantly close adherence to recommendations with three possible areas of improvement: fewer axillary procedures, an appraisal of radiotherapy practice following BCS and more investigation into tamoxifen prescription practices for DCIS.

Background: The National Breast Cancer Audit is an initiative of the Breast Section of the Royal Australasian College of Surgeons collecting surgical information in early breast cancer. It is managed in conjunction with the Australian Safety and Efficacy Register of New Interventional Procedures – Surgical. An overview of results for invasive breast cancer from January 1999 until December 2004 is presented to provide preliminary data for participating surgeons. Methods: Invasive breast cancer cases were retrieved from the National Breast Cancer Audit database for the 274 participating breast surgeons in Australia and New Zealand. Data for a variety of clinical parameters were analysed to provide an overview of the diagnostic, histological, surgical and adjuvant therapy management issues. Results: There were 25 026 cases of invasive breast cancer. Annual percentages of mammographically detected cancers from 1999 to 2004 did not differ significantly. Breast-conserving surgery rates also remained stable at 60%. Margins were involved in 5% of patients; an additional 9% had final margins of less than 1 mm. Radiotherapy followed breast-conserving surgery in most cases (86%). Patients undergoing mastectomy with large tumours (>5 cm) underwent radiotherapy in 71% of cases. When at least four lymph nodes were positive, radiotherapy followed mastectomy in the majority (75%) of cases. The most frequently carried out axillary procedure was a level 2 dissection. Chemotherapy was received by 78% of oestrogen receptor negative, axillary node positive, postmenopausal patients. Tamoxifen was used in the majority (83%) of oestrogen receptor positive cases. Conclusion: Surgeons contributing their invasive breast cancer data show a high quality of treatment. Some further improvement may be possibly related to excision margins and tamoxifen prescription for oestrogen receptor negative cancers. Chemotherapy prescription might also warrant further investigation. [ABSTRACT FROM AUTHOR]
