Antibodies were patterned onto flexible plastic filmsusing theflexographic printing process. An ink formulation was developed usinghigh molecular weight polyvinyl alcohol in carbonate–bicarbonatebuffer. In order to aid both antibody adhesion and the quality ofdefinition in the printed features, a nitrocellulose coating was developedthat was capable of being discretely patterned, thus increasing thesignal-to-noise ratio of an antibody array. Printing antibody featuressuch as dots, squares, text, and fine lines were reproduced effectively.Furthermore, this process could be easily adapted for printing ofother biological materials, including, but not limited to, enzymes,DNA, proteins, aptamers, and cells.

The article discusses the adverse effect of combination angiotensin II receptor blockers (ARBs) plus angiotension-converting enzyme (ACE) inhibitors in symptomatic left ventricular dysfunction. Eligible randomized controlled trials (RCTs) from MEDLINE and Web sites for the National Institute of Health Clinical Trials and the Food and Drug Administration were selected. Results from the four qualified studies showed that combination ARBs plus ACE inhibitors was associated with significant increases in medication discontinuations due to its adverse effects in patients with chronic heart failure and acute myocardial infarctions with symptomatic left ventricular dysfunction. Moreover, it also worsens renal function, hyperkalemia and symptomatic hypotension.

OBJECTIVE: The role of proton pump inhibitors (PPIs) in suspected GERD-related chronic laryngitis (CL) is controversial. Hence, we performed a meta-analysis of the existing randomized controlled trials (RCTs) to evaluate the efficacy of PPIs in this disorder. METHODS: Data extracted from MEDLINE (1966 to August 2005), Cochrane Controlled Trials Register (1997 to August 2005), EMBASE (1980 to August 2005), ClinicalTrials.gov website, and meetings presentations (1999–2005). Published and unpublished randomized placebo-controlled trials of PPIs in suspected GERD-related CL were selected by consensus. Random effects model was utilized with standard approaches to quality assessment, sensitivity analysis, and an exploration of heterogeneity and publication bias. The primary outcome measure was defined as the proportion of patients with ≥50% reduction in self-reported laryngeal symptoms. RESULTS: Pooled data from 8 studies (N = 344, PPI 195, placebo 149; mean age 51 yr; males 55%; study duration 8–16 wk) were analyzed. No significant quantitative heterogeneity was found among the studies (χ2= 11.22, P= 0.13). Overall, PPI therapy resulted in a nonsignificant symptom reduction compared to placebo (relative risk 1.28, 95% confidence interval 0.94–1.74). No clinical predictors of PPI response were identified on meta-regression analysis done at study level. CONCLUSIONS: PPI therapy may offer a modest, but nonsignificant, clinical benefit over placebo in suspected GERD-related CL. Validated diagnostic guidelines may facilitate the recognition of those patients most likely to respond favorably to PPI treatment. [ABSTRACT FROM AUTHOR]

This study examined how health services research connects with practice and policy, first by investigating whether successful research projects continued in their test settings and engendered replication and then by examining whether a coherent body of research helped shape public policy. Chronic heart failure (CHF) was studied because randomized, controlled trials of posthospital CHF disease management have repeatedly demonstrated patient benefits and reduced costs, yet this practice has not become standard in the United States. Literature review produced 30 randomized, controlled trials of multidisciplinary outpatient CHF management, generally yielding improved patient outcomes. An e-mail survey of first authors (97% response rate) showed that practices proven to be effective in U.S. studies generally did not continue or expand (13 of 15 studies), mostly attributed to financial constraints (11 of 13), whereas similar projects in other countries often became permanent (7 of 13). U.S. respondents generally rated current quality of clinical care as good, whereas those elsewhere mostly rated it as excellent. Recent Medicare reforms implemented a model of CHF management substantially different from those studied in health services research. The Congressional hearings leading to these Medicare reforms, and the statute itself, mostly evidence the model used by commercial disease-management firms. Policy-makers, health service researchers, and funding agencies could develop more-effective methods for translating proven models of healthcare delivery into routine practice. Reforms that might improve the effectiveness of the linkages between research, policy, and practice are suggested. [ABSTRACT FROM AUTHOR]

Abstract: Objectives: To determine whether a hierarchy of effectiveness exists with respect to complexity of published protocols of heart failure (HF) disease management (DM) incorporating specialist nurse-led HF clinics. Data sources and study selection: We searched MEDLINE (1966–November 2004), the Cochrane Library, article bibliographies, and contacted experts. Inclusion criteria were random allocation of at least 100 patients, specialist HF nurses, HF clinics, and readmission as an outcome measure. Data extraction: Paired reviewers conducted quality assessment, deconstructed and categorized protocols by complexity, and extracted results for readmission, mortality, the combined endpoint of mortality and hospitalization, HF readmission, and hospital days utilized. Data synthesis: Six trials were selected (N=949, mean age 73 years [range 62–79], men 58%, LVEF 34% [27–41], and average follow-up of 8.5 months [3–12]). Compared with usual care, the overall relative risk [95% confidence interval] for readmission with this strategy was 0.91 [0.72, 1.16], mortality was 0.80 [0.57, 1.06], and the combined endpoint of mortality and hospitalization was 0.88 [0.74, 1.04]. We observed better outcomes for programs with versus programs without hospital discharge planning and immediate post-discharge follow-up; readmission 0.30 [0.04, 2.60] vs. 1.00 [0.86, 1.17], mortality 0.96 [0.63, 1.47] vs. 0.75 [0.55, 1.03], the combined endpoint of mortality and hospitalization 0.61 [0.18, 2.02] vs. 0.91 [0.80, 1.03], HF readmission 0.09 [0.10, 0.65] vs. 0.65 [0.43, 1.00], and hospitalized days utilized per patient −0.26 [−0.49,−0.02] vs. 0.09 [−1.17, 1.34]. Conclusions: HF DM with specialist nurse-led HF clinics is a promising strategy or effective alternative whose benefit may be optimized by programs with a homogeneous structure and components that are delivered with consistency.

Context: Comprehensive discharge planning plus postdischarge support may reduce readmission rates for older patients with congestive heart failure (CHF). Objective: To evaluate the effect of comprehensive discharge planning plus postdischarge support on the rate of readmission in patients with CHF, all-cause mortality, length of stay (LOS), quality of life (QOL), and medical costs. Data Sources: We searched MEDLINE (1966 to October 2003), the Cochrane Clinical Trials Register (all years), Social Science Citation Index (1992 to October 2003), and other databases for studies that described such an intervention and evaluated its effect in patients with CHF. Where possible we also contacted lead investigators and experts in the field. Study Selection: We selected English-language publications of randomized clinical trials that described interventions to modify hospital discharge for older patients with CHF (mean age ≥55 years), delineated clearly defined inpatient and outpatient components, compared efficacy with usual care, and reported readmission as the primary outcome. Data Extraction: Two authors independently reviewed each report, assigned quality scores, and extracted data for primary and secondary outcomes in an unblinded standardized manner. Data Synthesis: Eighteen studies representing data from 8 countries randomized 3304 older inpatients with CHF to comprehensive discharge planning plus postdischarge support or usual care. During a pooled mean observation period of 8 months (range, 3-12 months), fewer intervention patients were readmitted compared with controls (555/1590 vs 741/1714, number needed to treat = 12; relative risk [RR], 0.75; 95% confidence interval [CI], 0.64-0.88). Analysis of studies reporting secondary outcomes found a trend toward lower all-cause mortality for patients assigned to an intervention compared with usual care (RR, 0.87; 95% CI, 0.73-1.03; n = 14 studies), similar initial LOS (mean [SE]: 8.4 [2.5] vs 8.5 [2.2] days, P = .60; n = 10), greater percentage improvement in QOL scores compared with baseline scores (25.7% [95% CI, 11.0%-40.4%] vs 13.5% [95% CI, 5.1%-22.0%]; n = 6, P = .01), and similar or lower charges for medical care per patient per month for the initial hospital stay, administering the intervention, outpatient care, and readmission (-$359 [95% CI, -$763 to $45]; n = 4, P = .10 for non-US trials and -$536 [95% CI, -$956 to -$115]; n = 4, P = .03, for US trials). Conclusion: Comprehensive discharge planning plus postdischarge support for older patients with CHF significantly reduced readmission rates and may improve health outcomes such as survival and QOL without increasing costs.

In this article, the author discusses the study of F. A. McAlister and colleagues regarding the use of the combination of angiotensin-receptor blockers and converting-enzyme inhibitors in the treatment of patients with heart failure. He is critical to the strength of the study, which according to him, is its consistency in terms of adverse drug effects as reported in clinical trials. He also mentions several clinical trials that affirm that the combination lessens morbidity.

In this article, the authors discuss the Women's Antioxidant and Folic Acid Cardiovascular Study (WAFACS), carried out by W.G. Christen and colleagues. The authors remark the significance of the study on public health to prevent the early stage development of age-related macular degeneration (AMD). The authors relate the development of advanced treatments for AMD as a major program of the U.S. National Eye Institute. The authors believe that the need for AMD treatments must be recognized.

The article presents a meta-analysis of randomized controlled trials on the effectiveness of proton pump inhibitor (PPI) therapy for the treatment of suspected Gastroesophageal Reflux Disease (GERD)-Related Chronic Laryngitis (CL). The analysis used random effects model with standard approaches to quality assessment, sensitivity analysis and an exploration of heterogeneity and publication bias. PPI therapy offer a nonsignificant clinical benefit over placebo in patients with GERD-related CL.

OBJECTIVE: To evaluate modern surgical outcomes in patients with stable heart failure undergoing elective major noncardiac surgery and to compare the experience of patients with heart failure who have reduced vs preserved left ventricular ejection fraction (EF). PATIENTS AND METHODS: We retrospectively studied 557 consecutive patients with heart failure (192 EF £40% and 365 EF >40%) and 10,583 controls who underwent systematic evaluation by hospitalists in a preoperative clinic before having major elective noncardiac surgery between January 1, 2003, and March 31, 2006. We examined outcomes in the entire cohort and in propensity-matched case-control groups. RESULTS: Unadjusted 1-month postoperative mortality in patients with both types of heart failure vs controls was 1.3% vs 0.4% (P=.009), but this difference was not significant in propensity-matched groups (P=.09). Unadjusted differences in mean hospital length of stay among heart failure patients vs controls (5.7 vs 4.3 days; P<.001) and 1-month readmission (17.8% vs 8.5%; P<.001) were also markedly attenuated in propensity-matched groups. Crude 1-year hazard ratios for mortality were 1.71 (95% confidence interval [CI], 1.5-2.0) for both types of heart failure, 2.1 (95% CI, 1.7-2.6) in patients with heart failure who had EF £40%, and 1.4 (95% CI, 1.2-1.8) in those who had EF >40% (P<.01 for all 3 comparisons); however, the differences were not significant in propensity-matched groups (P=.43). CONCLUSION: Patients with clinically stable heart failure did not have high perioperative mortality rates in association with elective major noncardiac surgery, but they were more likely than patients without heart failure to have longer hospital stays, were more likely to require hospital readmission, and had a substantial long-term mortality rate.

Objectives: This study was designed to determine whether admission B-type natriuretic peptide (BNP) levels are predictive of in-hospital mortality in acute decompensated heart failure (HF). Background: Levels of BNP have been demonstrated to facilitate the diagnosis of HF and predict mortality in chronic systolic HF. Methods: B-type natriuretic peptide levels within 24 h of presentation were obtained in 48,629 (63%) of 77,467 hospitalization episodes entered in ADHERE (Acute Decompensated Heart Failure National Registry). In-hospital mortality was assessed by BNP quartiles in the entire cohort and in patients with reduced (n = 19,544) as well as preserved (n = 18,164) left ventricular systolic function using chi-square and logistic regression models. Results: Quartiles (Q) of BNP were Q1 (<430), Q2 (430 to 839), Q3 (840 to 1,729), and Q4 (≥1,730 pg/ml). The BNP levels were <100 pg/ml in 3.3% of the total cohort. Patients in Q1 versus Q4 were younger, more likely to be women, and had lower creatinine and higher left ventricular ejection fraction. There was a near-linear relationship between BNP quartiles and in-hospital mortality: Q1 (1.9%), Q2 (2.8%), Q3 (3.8%), and Q4 (6.0%), p < 0.0001. B-type natriuretic peptide quartile remained highly predictive of mortality even after adjustment for age, gender, systolic blood pressure, blood urea nitrogen, creatinine, sodium, pulse, and dyspnea at rest, Q4 versus Q1 (adjusted odds ratio 2.23 [95% confidence interval 1.91 to 2.62, p < 0.0001]). The BNP quartiles independently predicted mortality in patients with reduced and preserved systolic function. Conclusions: An elevated admission BNP level is a significant predictor of in-hospital mortality in acute decompensated HF with either reduced or preserved systolic function, independent of other clinical and laboratory variables.

The article presents research findings and recommendations for the hand-off of discharged patient data from hospital-based physicians to primary care physicians. Common deficits in communication and information transfer included the availability, timeliness, content, and format of discharge communications, as well as primary care physician satisfaction. Measures of these deficits showed the communication problems to be common and with adverse effects on patient care. Recommendations include provision of computer-generated summaries of pertinent patient data and use of standardized formats for data presentation to primary care physicians.

Background: Small studies suggest that telemonitoring may improve heart-failure outcomes, but its effect in a large trial has not been established. Methods: We randomly assigned 1653 patients who had recently been hospitalized for heart failure to undergo either telemonitoring (826 patients) or usual care (827 patients). Telemonitoring was accomplished by means of a telephone-based interactive voice-response system that collected daily information about symptoms and weight that was reviewed by the patients' clinicians. The primary end point was readmission for any reason or death from any cause within 180 days after enrollment. Secondary end points included hospitalization for heart failure, number of days in the hospital, and number of hospitalizations. Results: The median age of the patients was 61 years; 42.0% were female, and 39.0% were black. The telemonitoring group and the usual-care group did not differ significantly with respect to the primary end point, which occurred in 52.3% and 51.5% of patients, respectively (difference, 0.8 percentage points; 95% confidence interval [CI], −4.0 to 5.6; P=0.75 by the chi-square test). Readmission for any reason occurred in 49.3% of patients in the telemonitoring group and 47.4% of patients in the usual-care group (difference, 1.9 percentage points; 95% CI, −3.0 to 6.7; P=0.45 by the chi-square test). Death occurred in 11.1% of the telemonitoring group and 11.4% of the usual care group (difference, −0.2 percentage points; 95% CI, −3.3 to 2.8; P=0.88 by the chi-square test). There were no significant differences between the two groups with respect to the secondary end points or the time to the primary end point or its components. No adverse events were reported. Conclusions: Among patients recently hospitalized for heart failure, telemonitoring did not improve outcomes. The results indicate the importance of a thorough, independent evaluation of disease-management strategies before their adoption.

B-type natriuretic peptide (BNP) and cardiac troponin (Tn) I or T have been demonstrated to provide prognostic information in patients with acute coronary syndromes. Whether admission BNP and Tn levels provide additive prognostic value in acutely decompensated heart failure (HF) has not been well studied. Hospitalizations for HF from April 2003 to December 2004 entered into ADHERE were analyzed. BNP assessment on admission was performed in 48,629 (63%) of 77,467 hospitalization episodes. Tn assessment was performed in 42,636 (88%) of these episodes. In-hospital mortality was assessed using logistic regression models adjusted for age, gender, blood urea nitrogen, systolic blood pressure, creatinine, sodium, pulse, and dyspnea at rest. Median BNP was 840 pg/ml (interquartile range 430 to 1,730). Tn was increased in 2,370 (5.6%) of 42,636 HF episodes. BNP above the median and increased Tn were associated with significantly increased risk of in-hospital mortality (odds ratios [OR] 2.09 and 2.41 respectively, each p value <0.0001). Mortality was 10.2% in patients with BNP ≥840/Tn increased compared with 2.2% with BNP <840/Tn not increased (OR 5.10, p <0.0001). After covariate adjustment, mortality risk remained significantly increased with BNP ≥840/Tn not increased (adjusted OR 1.56, 95% confidence interval 1.40 to 1.79, p <0.0001), BNP <840/Tn increased (adjusted OR 1.69, 95% confidence interval 1.17 to 2.45, p = 0.006), and BNP ≥840/Tn increased (adjusted OR 3.00, 95% confidence interval 2.47 to 3.66, p <0.0001). Admission BNP and cardiac Tn levels are significant, independent predictors of in-hospital mortality in acutely decompensated HF. Patients with BNP levels ≥840 pg/ml and increased Tn levels are at particularly high risk for mortality. In conclusion, a multimarker strategy for the assessment of patients hospitalized with HF adds incremental prognostic information. [Copyright &y& Elsevier]

Racial and ethnic minorities often receive lower-quality health care than white patients, even when socioeconomic status, education, access, and other factors are used as controls. To address these pervasive disparities, health care professionals should learn more about them and the roles they can play in eliminating them, but few curricula are focused on understanding and addressing racial and ethnic health disparities, and well-accepted guidelines on what and how to teach in this complex area are lacking. The Society of General Internal Medicine Health Disparities Task Force used a review and consensus process to develop specific recommendations and guidelines for curricula focusing on health disparities. Learning objectives, content, methods for teaching, and useful resources are provided. Although the guidelines were developed primarily for teaching medical students, residents, and practitioners in primary care, the Task Force's general recommendations can apply to learners in any specialty. The Task Force recommends that a curricula address 3 areas of racial and ethnic health disparities and focus on the following specific learning objectives: 1) examining and understanding attitudes, such as mistrust, subconscious bias, and stereotyping, which practitioners and patients may bring to clinical encounters; 2) gaining knowledge of the existence and magnitude of health disparities, including the multifactorial causes of health disparities and the many solutions required to diminish or eliminate them; and 3) acquiring the skills to effectively communicate and negotiate across cultures, languages, and literacy levels, including the use of key tools to improve communication. The broad goal of a curriculum on disparities should be for learners to develop a commitment to eliminating inequities in health care quality by understanding and assuming their professional role in addressing this pressing health care crisis.

Context: Delayed or inaccurate communication between hospital-based and primary care physicians at hospital discharge may negatively affect continuity of care and contribute to adverse events.Objectives: To characterize the prevalence of deficits in communication and information transfer at hospital discharge and to identify interventions to improve this process.Data Sources: MEDLINE (through November 2006), Cochrane Database of Systematic Reviews, and hand search of article bibliographies.Study Selection: Observational studies investigating communication and information transfer at hospital discharge (n = 55) and controlled studies evaluating the efficacy of interventions to improve information transfer (n = 18).Data Extraction: Data from observational studies were extracted on the availability, timeliness, content, and format of discharge communications, as well as primary care physician satisfaction. Results of interventions were summarized by their effect on timeliness, accuracy, completeness, and overall quality of the information transfer.Data Synthesis: Direct communication between hospital physicians and primary care physicians occurred infrequently (3%-20%). The availability of a discharge summary at the first postdischarge visit was low (12%-34%) and remained poor at 4 weeks (51%-77%), affecting the quality of care in approximately 25% of follow-up visits and contributing to primary care physician dissatisfaction. Discharge summaries often lacked important information such as diagnostic test results (missing from 33%-63%), treatment or hospital course (7%-22%), discharge medications (2%-40%), test results pending at discharge (65%), patient or family counseling (90%-92%), and follow-up plans (2%-43%). Several interventions, including computer-generated discharge summaries and using patients as couriers, shortened the delivery time of discharge communications. Use of standardized formats to highlight the most pertinent information improved the perceived quality of documents.Conclusions: Deficits in communication and information transfer at hospital discharge are common and may adversely affect patient care. Interventions such as computer-generated summaries and standardized formats may facilitate more timely transfer of pertinent patient information to primary care physicians and make discharge summaries more consistently available during follow-up care.

Objectives: We sought to best estimate the benefits and risks associated with rescue percutaneous coronary intervention (PCI) and repeat fibrinolytic therapy as compared with conservative management in patients with failed fibrinolytic therapy for ST-segment myocardial infarction (STEMI). Background: Fibrinolytic therapy is the most common treatment for STEMI; however, the best therapy in patients who fail to achieve reperfusion after fibrinolytic therapy remains uncertain. Methods: We performed a meta-analysis of randomized trials using a fixed-effects model. We included 8 trials enrolling 1,177 patients with follow-up duration ranging from hospital discharge to 6 months. Results: Rescue PCI was associated with no significant reduction in all-cause mortality (relative risk [RR] 0.69; 95% confidence interval [CI] 0.46 to 1.05), but was associated with significant risk reductions in heart failure (RR 0.73; 95% CI 0.54 to 1.00) and reinfarction (RR 0.58; 95% CI 0.35 to 0.97) when compared with conservative treatment. Rescue PCI was associated with an increased risk of stroke (RR 4.98; 95% CI 1.10 to 22.5) and minor bleeding (RR 4.58; 95% CI 2.46 to 8.55). Repeat fibrinolytic therapy was not associated with significant improvements in all-cause mortality (RR 0.68; 95% CI 0.41 to 1.14) or reinfarction (RR 1.79; 95% CI 0.92 to 3.48), but was associated with an increased risk for minor bleeding (RR 1.84; 95% CI 1.06 to 3.18). Conclusions: Rescue PCI is associated with improved clinical outcomes for STEMI patients after failed fibrinolytic therapy, but these benefits must be interpreted in the context of potential risks. On the other hand, repeat fibrinolytic therapy is not associated with significant clinical improvement and may be associated with increased harm. [Copyright &y& Elsevier]

Objectives: We estimated the prevalence of renal impairment in heart failure (HF) patients and the magnitude of associated mortality risk using a systematic review of published studies. Background: Renal impairment in HF patients is associated with excess mortality, although precise risk estimates are unclear. Methods: A systematic search of MEDLINE (through May 2005) identified 16 studies characterizing the association between renal impairment and mortality in 80,098 hospitalized and non-hospitalized HF patients. All-cause mortality risks associated with any renal impairment (creatinine >1.0 mg/dl, creatinine clearance [CrCl] or estimated glomerular filtration rate [eGFR] <90 ml/min, or cystatin-C >1.03 mg/dl) and moderate to severe impairment (creatinine ≥1.5, CrCl or eGFR <53, or cystatin-C ≥1.56) were estimated using fixed-effects meta-analysis. Results: A total of 63% of patients had any renal impairment, and 29% had moderate to severe impairment. After follow-up ≥1 year, 38% of patients with any renal impairment and 51% with moderate to severe impairment died versus 24% without impairment. Adjusted all-cause mortality was increased for patients with any impairment (hazard ratio [HR] = 1.56; 95% confidence interval [CI] 1.53 to 1.60, p < 0.001) and moderate to severe impairment (HR = 2.31; 95% CI 2.18 to 2.44, p < 0.001). Mortality worsened incrementally across the range of renal function, with 15% (95% CI 14% to 17%) increased risk for every 0.5 mg/dl increase in creatinine and 7% (95% CI 4% to 10%) increased risk for every 10 ml/min decrease in eGFR. Conclusions: Renal impairment is common among HF patients and confers excess mortality. Renal function should be considered in risk stratification and evaluation of therapeutic strategies for HF patients. [Copyright &y& Elsevier]
