DISCUSSION with patients, the rationale for links workers is that, if individuals feel supported in their lives, then they are more likely to respond to information on ways to improve their health and to live well. If these people were to be successfully supported sooner rather than later, then there is a potential that their risk of developing LTCs would be reduced, or further complications delayed or prevented if they have already contracted long-term illness(es). The PCAM is probably most similar to the Links Worker model in its aims. The Links Worker Programme commenced during the PCAM study and its evaluation is still under way. Therefore, the evidence base for the Links Worker Programme is still unclear. However, there is still a need in primary care for nurses (and GPs) who see the majority of patients with LTCs to be able to feel confident in determining whether or not patients have any problems that could be dealt with by the links worker. The completion of the PCAM tool in annual reviews could act as a facilitator for referral to those in links worker-type roles, who could then facilitate access to community-based resources. The two initiatives are more compatible than incompatible, and could strengthen the identification of needs and communication between the primary care team and the links worker. It is also unclear who will fund, and whether or not they will fund, the continuation of the links worker roles in Scotland, and these are not available across the UK. Therefore, the PCAM may still be the best method available for the promotion of biopsychosocial assessment in primary care and, with the development of a locally derived resource pack, could also be the best-available method for facilitating access to a broader range of psychosocial supports. In conclusion, we believe that the PCAM is uniquely developed for primary care and we are not aware of directly comparable assessment tools that have been prepared for and tested in primary care. The PCAM provides a comprehensive and practical approach via the three components of training, the PCAM tool and the resource toolkit. Other initiatives like HoC lack an easily understood and easy-to-use practical tool. The use of the PCAM by primary care nurses as a decision aid for referral to links-type roles in primary care would work really well. Links-type roles could also make use of the PCAM itself. The PCAM could serve as a systematic way of recording needs and actions to be shared across the primary care team (GPs, nurses, links or other social care roles). Patient and public involvement One of the key benefits of including PPI in clinical trials and on trial design is that they are likely to make studies more feasible, at least in terms of patient recruitment. Research has shown that trials with higher levels of PPI are four times more likely to recruit to target. These can help to identify necessary adjustments to improve recruitment and retention. The PPI partners in this study did indeed help to shape the recruitment strategy for patients, which was to opt in to either a focus group study or involved opting in to completing questionnaires and a possible interview. The outcomes needed to include measures of physical health, mental health and social needs. We also required information on actions undertaken by nurses (advice, referrals, signposting) and on whether or not patients had taken up this advice, referral or signposting to services. The complexity of the study design, and its attempt to gather multiple outcomes at both the nurse level and the patient level, was not lost on our PPI members, as we worked together to gather the required knowledge in the most efficient manner. This was probably helped by the degree of knowledge of research that our PPI members had and their enthusiasm for the study. They contributed to the many discussions throughout the study on how to address this and were reassured that the team had tried all possible avenues within the time scale available to achieve practice recruitment and retention. In reflecting on our PPI as a team, we thought it best to allow our PPI members to write their own contributions to this. We asked them to reflect on their experience of working with us and whether or not we could have done anything differently to enable their participation in the study. Their responses are included in the following two subsections.

Thus, some of the discrepancy in both feasible and safe.

Te information in this report updates the 2006 Guidelines for Treatment of Sexually Transmitted Diseases (MMWR 2006;55[No. Included in these updated guidelines is new information regarding 1) the expanded diagnostic evaluation for cervicitis and trichomoniasis; 2) new treatment recommendations for bacterial vaginosis and genital warts; 3) the clinical efcacy of azithromycin for chlamydial infections in pregnancy; 4) the role of Mycoplasma genitalium and trichomoniasis in urethritis/cervicitis and treatment-related implications; 5) lymphogranuloma venereum proctocolitis among men who have sex with men; 6) the criteria for spinal fuid examination to evaluate for neurosyphilis; 7) the emergence of azithromycin-resistant Treponema pallidum; 8) the increasing prevalence of antimicrobial-resistant Neisseria gonorrhoeae; 9) the sexual transmission of hepatitis C; 10) diagnostic evaluation after sexual assault; and 11) STD prevention approaches.

These experiments suggest that ANP secretion plays an important role in 2 maintaining Na excretion in compensated congestive heart failure. Low-output heart failure was induced in dogs by thoracic inferior vena ANP & AII caval constriction (TIVCC), which also led to a significant decrease in renal perfusion 200 ANP & AII & SAR pressure (RPP) (from 127 to 120 m m H g).

In contrast, when the RPP 100 was returned to baseline by infusing angiotensin II (AII), urinary N a excretion increased greatly (AN P + AII). To exclude a direct effect of AII on urinary N a excretion, intrarenal 0 saralasin (SAR) was infused to block renal AII receptors. SAR did not significantly affect Baseline TIVCC Infusion the natriuresis induced by AN P plus AII. An independent effect of SAR on urinary N a excretion was excluded by infusing AN P plus SAR and AII plus SAR. These results were interpreted as indicating that the predom inant cause of resistance to AN P in dogs with low-output congestive heart failure is a reduction in RPP.
