    Notes: This study explores and compares the privacy concerns of primary care nurse practitioners (NPs) and their patients.〈section xml:id="abs1-2"〉〈title type="main"〉Data sourcesPrivacy concerns were identified in separate focus groups of NPs and patients, and then parallel survey instruments were designed and administered to 27 NPs and 185 of their patients. All subjects were recruited through APRNet, a regional practice-based research network of NPs in southern New England encompassing 58 practices.〈section xml:id="abs1-3"〉〈title type="main"〉ConclusionsBoth groups demonstrated high levels of concern regarding privacy. While NPs and patients had similar levels of concern about most issues, there were some notable differences regarding breeches because of carelessness, disclosures for research, and which disorders require the most care in maintaining privacy.〈section xml:id="abs1-4"〉〈title type="main"〉Implications for practiceThese results allow NPs to anticipate patient privacy concerns and to enhance trust in the clinical relationship. These results also indicate the need to educate patients regarding privacy rights and expectations.

    Notes: Objective: As atrial conduction slowing is important in the pathogenesis of atrial reentry arrhythmias, a drug that increases atrial conduction or prevents atrial conduction slowing could serve to prevent atrial reentry arrhythmias. In this study, we investigated whether the novel stable antiarrhythmic peptide analog, ZP123, was able to prevent atrial conduction slowing. Methods: We examined the effect of ZP123 on metabolic stress-induced changes in conduction velocity (CV) and on dynamic CV restitution in isolated left atria from male Sprague-Dawley rats. We performed binding of ZP123 to a broad panel of 80 different cardiac and noncardiac ion channels and receptors and examined the effect of ZP123 on HERG channel conductance. Results: ZP123 dose-dependently prevented metabolic stress-induced atrial CV slowing at doses ranging from 1 nM to 10 μM. ZP123 did not affect CV during physiological conditions nor did it affect dynamic CV restitution. ZP123 had no effect on atrial contractility. ZP123 showed no or low affinity binding to all ion channels and receptors examined. ZP123 had no effects on HERG channel activity in concentrations that affected atrial conduction. The concentration of ZP123 giving maximal effect on atrial conduction (100 nM) inhibited the outward K+-current by 2.7 ± 0.1%. Conclusion: ZP123 has no effects on atrial conduction during physiological conditions, but it selectively prevents atrial conduction slowing during metabolic stress.

    Notes: Abstract  Advances in endoluminal technology have enabled interventionists to treat a variety of pathologies that traditionally would require open surgery. Although excluding descending thoracic aortic aneurysms seems feasible, thoracic aortic dissection and its complications are an area in which the appropriateness of endovascular therapy has yet to be defined. Five case reports are presented, each with varying pathologies associated with type III dissections. The follow-up of the cases ranged from 6 to 18 months with a mean of 12.2 months. The endovascular approach and the technical aspect of the intervention have been emphasized in each case. (J Card Surg 2003; 18:334-350)
