Impact of platelet turnover on long-term adverse cardiovascular outcomes in patients undergoing percutaneous coronary intervention.

BACKGROUND: Increased platelet turnover and high platelet reactivity are associated with short-term major adverse cardiovascular events (MACE) after percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) or stable coronary artery disease (SCAD). We investigated the impact of platelet turnover on long-term MACE. METHODS: Consecutive patients presenting with ACS or SCAD undergoing PCI between 2009 and 2010 were included. All patients received clopidogrel and aspirin as dual antithrombotic therapy regimen. Multivariable Cox proportional hazard models were applied to assess the prognostic impact of platelet turnover (reticulated platelet count [RPC], mean platelet volume [MPV]) and function on long-term MACE, a composite of cardiovascular death, nonfatal myocardial infarction and nonfatal stroke. RESULTS: In total, 477 patients were eligible. Mean age was 64.3 ± 12.7 years, 68.8% were male. Median follow-up was 5.8 (IQR 4.2-6.5) years. Median RPC was 7.6 (IQR 5.6-10.4) g/L and median MPV was 10.7 (IQR 10.1-11.3) fL. In univariable analysis, RPC was associated with MACE, both as continuous (HR 1.064 [95%CI 1.021-1.111]; P = .006) and dichotomized (HR 1.693 [95%CI 1.156-2.481]; P = .006) variable. After adjustment, continuous RPC (HR 1.055 [95%CI 1.012-1.099]; P = .010) and dichotomized RPC (HR 1.716 [95%CI 1.152-2.559]; P = .007) remained significantly associated with MACE. Neither MPV nor platelet function testing was associated with long-term adverse outcome. CONCLUSION: Increased platelet turnover is associated with long-term adverse outcome in patients with coronary artery disease undergoing PCI. Platelet turnover represents a new marker of atherothrombotic risk and might help to guide composition or duration of antiplatelet therapy.

Characteristics of patients initiated on edoxaban in Europe: baseline data from edoxaban treatment in routine clinical practice for patients with atrial fibrillation (AF) in Europe (ETNA-AF-Europe).

BACKGROUND: Non-vitamin K antagonist (VKA) oral anticoagulants (NOACs) have substantially improved anticoagulation therapy for prevention of stroke and systemic embolism in patients with atrial fibrillation (AF). The available routine care data have demonstrated the safety of different NOACs; however, such data for edoxaban are scarce. Here, we report baseline characteristics of 13,638 edoxaban-treated patients with AF enrolled between November 2016 and February 2018. METHODS: ETNA-AF-Europe is a multinational, multi-centre, post-authorisation, observational study conducted in 825 sites in 10 European countries. Patients will be followed up for four years. RESULTS: Overall, 13,980 patients were enrolled of which 342 patients were excluded from the analysis. Mean patient age was 73.6 years with an average creatinine clearance of 69.4 mL/min. 56.6% were male. The calculated CHA2DS2-VASc and HAS-BLED mean scores were 3.1 and 2.6, respectively. Overall, 3.3, 14.6 and 82.0% of patients had low (CHA2DS2-VASc = 0), intermediate (CHA2DS2-VASc = 1) and high (CHA2DS2-VASc≥2) risks of stroke, respectively. High-risk patients (those with prior stroke, prior major bleeding, prior intracranial bleed or CHA2DS2-VASc ≥4) comprised 38.4% of the overall population. For 75.1% of patients edoxaban was their first anticoagulant prescription, whilst 16.9% switched from a VKA and 8.0% from another NOAC. A total of 23.4% of patients in ETNA-AF-Europe received the reduced dose of edoxaban 30 mg. Overall, 83.8% of patients received an edoxaban dose in line with the criteria outlined in the label. CONCLUSION: Edoxaban was predominantly initiated in older, often anticoagulation-naïve, unselected European patients with AF, with a good overall adherence to the approved label. TRIAL REGISTRATION: NCT02944019; Date of registration: October 24, 2016.

[Edoxaban for stroke prevention in atrial fibrillation and treatment of venous thromboembolism: an expert position paper]. / Edoxaban zur Schlaganfallprophylaxe bei Patienten mit nicht-valvulärem Vorhofflimmern und zur Behandlung venöser Thromboembolien: ein interdisziplinäres Positionspapier.

Edoxaban is the most recent available representative of the Non-Vitamin K antagonist oral anticoagulants (NOAC). The approval was based on the largest phase III trials of NOACs for stroke prevention in patients with non-valvular atrial fibrillation (AF, ENGAGE-AF), and for the treatment of venous thromboembolism (VTE, HOKUSAI-VTE). In both trials, edoxaban was associated with similar efficacy and a significant reduction in bleeding events with respect to the pre-defined primary safety endpoints, as compared to warfarin.Additionally, the once daily dosing of edoxaban, the clinically investigated strategy for dose-reduction based on clearly defined criteria and the favorable pharmacokinetic profile might further support the clinical applicability of the substance.In the light of recent data, this expert consensus document aims to summarize the latest clinical trial results while providing a concise overview of current guideline recommendations on the management of patients with non-valvular AF and VTE.

A Double-Blinded Randomized Study Investigating a Possible Anti-Inflammatory Effect of Saxagliptin versus Placebo as Add-On Therapy in Patients with Both Type 2 Diabetes And Stable Coronary Artery Disease.

BACKGROUND: Promising results regarding potential anti-inflammatory and antiatherosclerotic effects of gliptins have been reported. Our aim was to investigate whether saxagliptin treatment modifies expression of inflammatory markers, primarily in peripheral blood mononuclear cells (PBMCs) and in circulating leukocytes in patients with stable coronary artery disease (CAD) and T2DM. METHODS: Patients (n = 12) were randomized to saxagliptin 5 mg daily or placebo for 3 months. Samples were taken at baseline and end of study in fasting state prior to intake of medications. PBMCs were isolated and cryopreserved at -150°C until ex vivo exposed to 1 ng/mL of lipopolysaccharide (LPS) for 4 hours. Gene expression was performed with custom-designed TaqMan® Arrays and relative quantification by real-time PCR (RT-qPCR). RESULTS: HbA1c was reduced in the saxagliptin-treated group compared to that in the change with placebo (p = 0.042). In unstimulated PBMCs and in circulating leukocytes, we observed a significant increase in IL-10 expression in the saxagliptin group (p = 0.043, both), significantly different from that in the placebo (p = 0.009 and p = 0.032, resp.). No between group differences in changes were observed in any of the selected proinflammatory markers. CONCLUSION: In our small cohort of patients with combined T2DM and CAD, a possible anti-inflammatory effect of saxagliptin, observed in the present study by upregulation of IL-10 in leukocytes, needs to be confirmed in larger studies.

Associations of Anogenital Low-Risk Human Papillomavirus Infection With Cancer and Acquisition of HIV.

α-Mucosal human papillomavirus (HPV) types are implicated in a range of clinical conditions and categorized as "low-risk" (LR) and "high-risk" (HR) types according to their degree of association with cervical cancers. The causative role of LR HPV infection in the development of anogenital warts and in low-grade squamous intraepithelial lesions is well established. In addition, there is a growing body of evidence that infection with LR HPV types may be associated with an elevated risk of cancers and potentiation of coinfections. Prospective and case-control studies consistently report a higher risk of anogenital cancers in men and women with a history of anogenital warts. Based on currently available evidence, this higher risk may be due to shared exposure to HR HPV types or an underlying immune impairment, rather than a direct role of LR HPV types in subsequent cancer risk. Data also suggest that infection with LR HPV, HR HPV, or both may increase the risk of HIV acquisition, although the relative contribution of different HPV types is not yet known. There is also evidence implicating HPV clearance, rather than HPV infection, in increased risk of HIV acquisition.

Effects of diet and/or n-3 fatty acid supplementation on components of the interleukin-6 trans-signalling system in elderly men.

BACKGROUND: It has previously been shown that both very long chain omega-3 polyunsaturated fatty acids (n-3 PUFA) and a Mediterranean-like diet (Md), are able to reduce the risk of cardiovascular (CV) mortality and morbidity. The exact mechanisms behind this effect are yet to be established. To date, there exist no data on the effect of n-3 PUFA supplementation and Md on components of the interleukin-6 (IL-6) trans-signalling (ts) system that plays a central role in the family of pro-atherosclerotic inflammatory markers. METHODS: A total of 563 men were included in the DOIT study, a randomised factorial-designed trial comparing the effect of 36 months of dietary counseling, n-3 PUFA supplementation (2.4 g/d), or both on different circulating biomarkers of atherosclerosis in elderly high-risk men. We used commercially available ELISA methods to analyse circulating levels of soluble glycoprotein 130 (sGP130), soluble IL-6 receptor (sIL-6r), and IL-6. RESULTS: There was no significant effect of either of the intervention principles on circulating levels of sGP130 or sIL-6r. We have shown previously that there is no effect on IL-6 concentrations either. CONCLUSIONS: This is the largest trial analysing possible effects of Md or n-3 PUFA supplementation on the IL-6ts system. Although the reduction of CV risk through dietary intervention or n-3 PUFA supplementation has previously been linked to anti-inflammatory effects, we could not find an effect of these interventions on the IL-6ts system. This indicates that the beneficial effects of Md or n-3 PUFA observed in previous studies seem to be independent of the IL-6ts system.

An increase of interleukin-33 serum levels after coronary stent implantation is associated with coronary in-stent restenosis.

The study aim was to determine the predictive value of interleukin (IL)-33, a recently described member of the IL-1 family of cytokines, for the development of in-stent restenosis (ISR). IL-33 serum levels were measured in 387 consecutive patients undergoing percutaneous coronary intervention (PCI) of whom 193 had stable angina, 93 non-ST elevation myocardial infarction (NSTEMI), and 101 ST-elevation MI (STEMI), respectively. Blood was taken directly before and 24h after stent implantation. The presence of ISR was initially evaluated by clinical means after six to eight months. When presence of myocardial ischemia was suspected, coronary angiography was performed to confirm the suspected diagnosis of ISR. Clinical ISR was present in total in 34 patients (8.8%). IL-33 was detectable in 185 patients and was below detection limit in 202 patients. In patients with decreased IL-33 (n=95), unchanged or non-detectable levels (n=210) or increased levels of IL-33 after PCI (n=82), ISR-rate was 2.1%, 9.5% and 14.6%, respectively (p<0.05). Accordingly, patients with ISR showed a significant increase of IL-33 upon PCI (p<0.05). This association was independent from clinical presentation and risk factors as well as numbers and type of stents. In patients with both stable and unstable coronary artery disease, an increase of IL-33 serum levels after stent implantation is associated with a higher rate of in-stent restenosis.

Understanding healthcare providers' preferred attributes of pediatric pneumococcal conjugate vaccines in the United States.

As higher-valent pneumococcal conjugate vaccines (PCVs) become available for pediatric populations in the US, it is important to understand healthcare provider (HCP) preferences for and acceptability of PCVs. US HCPs (pediatricians, family medicine physicians and advanced practitioners) completed an online, cross-sectional survey between March and April 2023. HCPs were eligible if they recommended or prescribed vaccines to children age <24 months, spent ≥25% of their time in direct patient care, and had ≥2 y of experience in their profession. The survey included a discrete choice experiment (DCE) in which HCPs selected preferred options from different hypothetical vaccine profiles with systematic variation in the levels of five attributes. Relative attribute importance was quantified. Among 548 HCP respondents, the median age was 43.2 y, and the majority were male (57.9%) and practiced in urban areas (69.7%). DCE results showed that attributes with the greatest impact on HCP decision-making were 1) immune response for the shared serotypes covered by PCV13 (31.4%), 2) percent of invasive pneumococcal disease (IPD) covered by vaccine serotypes (21.3%), 3) acute otitis media (AOM) label indication (20.3%), 4) effectiveness against serotype 3 (17.6%), and 5) number of serotypes in the vaccine (9.5%). Among US HCPs, the most important attribute of PCVs was comparability of immune response for PCV13 shared serotypes, while the number of serotypes was least important. Findings suggest new PCVs eliciting high immune responses for serotypes that contribute substantially to IPD burden and maintaining immunogenicity against serotypes in existing PCVs are preferred by HCPs.

Long-term effectiveness and safety of edoxaban in patients with atrial fibrillation: 4-year data from the ETNA-AF-Europe study.

BACKGROUND: To assess long-term effectiveness and safety of edoxaban in Europe. METHODS AND RESULTS: ETNA-AF-Europe, a prospective, multinational, multi-centre, post-authorisation, observational study was conducted in agreement with the European Medicines Agency. The primary and secondary objectives assessed real-world safety (including bleeding and deaths) and effectiveness (including stroke, systemic embolic events and clinical edoxaban use), respectively. Median (interquartile range) age of the 13,164 patients was 75.0 (68.0-80.0) years; CHA2DS2-VASc and HAS-BLED scores were 3.0 (2.0-4.0) and 2.0 (1.0-2.0), respectively. Follow-up duration was 3.98 (3.21-4.05) years. Patients on edoxaban 30 mg (n = 3042) at baseline were older (80.0 vs 73.0 years), more likely assessed as frail by investigators (27.0% vs 6.6%) and had more comorbidities than those on edoxaban 60 mg (n = 9617; missing dosing information for n = 505). Annualised event rates of all-cause and cardiovascular death in the overall population, edoxaban 60 mg and edoxaban 30 mg groups were 4.1%, 2.8% and 8.4%, and 1.0%, 0.7% and 2.0%, respectively. Annualised rates of stroke were relatively constant throughout the follow-up, transient ischaemic attack and systemic embolism were < 1% in the overall population. Rates of any major and major gastrointestinal bleeding were low, with slightly higher rates for edoxaban 30 vs 60 mg group. Intracranial haemorrhage was uncommon (0.2%). CONCLUSIONS: In European patients with AF, long-term therapy with edoxaban is associated with low and relatively constant annualised rates of stroke and major bleeding. Differences in outcomes between the two approved doses are attributable to differences in clinical characteristics.

Pharmacist interventions to improve blood pressure control in primary care: a cluster randomised trial.

BACKGROUND: High blood pressure (BP) is the single largest contributor to mortality world-wide. AIM: To investigate the effectiveness of a pharmacists-led intervention to improve BP control using automated office blood pressure (AOBP). METHOD: In this prospective parallel group, unblinded, cluster-randomised trial, 54 pharmacies enrolled pre-treated patients with uncontrolled AOBP above 135/85 mmHg. In the interventional group, pharmacists referred patients to the treating physician for therapy intensification in a structured fashion. In the control group, AOBP was recorded until the end of the trial. The primary endpoint was the proportion of patients achieving BP control at the threshold of 135/85 mmHg after 10 weeks. Key secondary endpoints were systolic AOBP reductions after 10 and 20 weeks. RESULTS: A total of 497 patients were included between 2017 and 2019. In the interventional and control group, 61.5% and 19.8% of patients underwent a therapy modification within 20 weeks. The primary endpoint was achieved in 38.8% in the interventional group and 31.2% in the control group (mean difference 7.6%, 95% CI -8.1; 23.3, p = 0.336). Mean systolic AOBP reductions were greater in the interventional vs. control group at 10 and 20 weeks (14.3 ± 7.4 vs. 6.9 ± 7.0 mmHg, mean difference 7.3 mmHg, 95% CI 3.2;11.5, p < 0.001, and 15.5 ± 9.0 vs. 9.8 ± 7.5 mmHg, mean difference 5.8 mmHg, 95% CI 0.8;10.7, p = 0.023). Atrial fibrillation was newly detected in 7.8% of patients. CONCLUSION: Through a pragmatic pharmacist-led disease management program, BP control was improved over time, without significant differences between groups. Greater systolic AOBP reductions were observed in the interventional vs. control group.

Outcomes of Patients Who Undergo Elective Covered Stent Treatment for Coronary Artery Aneurysms.

BACKGROUND: Coronary artery aneurysms (CAA) are reported in up to 5% of patients undergoing coronary angiography. Treatment of CAAs with covered stents has been reported in several case reports, however there is limited evidence available on the effectiveness and safety of this interventional practice. PURPOSE: To evaluate the current practice and outcomes of elective treatment of coronary artery aneurysms with covered stents. METHODS: We conducted a systematic review of published case reports and case series of patients presenting with CAA that have been treated with covered stents in a non-emergency setting. RESULTS: A total of 63 case reports and 3 case series were included in the final analysis comprising data from 81 patients. The treated CAA was situated in a native coronary artery in 92.6%, and in a saphenous vein graft in 7.4%. Procedural success was achieved in 95.1%. The types of stents used were mainly polytetrafluoroethylene (75.3%) and Papyrus (11.1%). In 11.0% of cases additional abluminal drug eluting stents (DES) and in 6.8% additional adluminal DES were implanted. After a mean follow up of 13.4 months overall major adverse cardiovascular events (MACE), mortality, myocardial infarction, stroke, stent thrombosis and target lesion revascularization were reported in 26.2, 0.0, 7.6, 0.0, 4.6 and 18.5% of cases, respectively. CONCLUSIONS: The use of covered stents for elective treatment of CAA appears to be effective and reasonably safe. Nevertheless, it is associated with higher MACE rate, driven mainly by higher target lesion revascularization. Further studies, particularly in form of randomized trials and controlled registries are warranted to identify patients who might profit the most from this procedure.

Left vs. right radial approach for coronary catheterization: Relation to age and severe aortic stenosis.

Background: Old age and the presence of aortic stenosis are associated with the unfolding of the intrathoracic aorta. This may result in increased difficulties navigating catheters from the right compared to the left radial approach. Objective: To investigate whether increasing age or presence of severe aortic stenosis was associated with increased catheterization success rates from left (LRA) compared to right radial artery approach (RRA). Methods: We compared coronary angiography success rates of RRA and LRA according to different age groups and in a subgroup of patients with severe aortic stenosis. Results: A total of 21,259 coronary angiographies were evaluated. With increasing age, the first pass success rate from either radial access decreased significantly (p < 0.001). In patients aged <85 years, there was no difference between LRA and RRA. However, in patients aged ≥85 years, LRA was associated with significantly higher success rates compared to RRA (90.1 vs. 82.8%, p = 0.003). Patients aged ≥85 years received less contrast agent and had shorter fluoroscopy time when LRA was used [86.6 ± 41.1 vs. 99.6 ± 48.7 ml (p < 0.001) and 4.5 ± 4.1 min vs. 6.2 ± 5.7 min (p < 0.001), mean (±SD)]. In patients with severe aortic stenosis (n = 589) better first pass success rates were observed via LRA compared to the RRA route (91.9 vs. 85.1%, p = 0.037). Conclusion: LRA, compared to RRA, is associated with a higher first-pass catheter success rate for coronary artery angiography in patients aged ≥85 years and those with severe aortic stenosis.

Neurotensin and Adverse Cardiovascular Outcomes in Patients Undergoing Percutaneous Coronary Intervention.

Background: Neurotensin is involved in fatty acid and glucose metabolism and promotes the development of obesity and diabetes. These associations appear to be more pronounced in women. We investigated the association of neurotensin with long-term major adverse cardiovascular events (MACE) in patients presenting with acute coronary syndrome (ACS) or chronic coronary syndrome (CCS) undergoing percutaneous coronary intervention (PCI). Methods: We included 452 consecutive patients [144 (31.9%) females] undergoing PCI for ACS or CCS. Plasma samples drawn after PCI were analyzed for neurotensin with an enzyme-linked immunoassay. As primary endpoint, a composite of MACE including all-cause death, non-fatal myocardial infarction and non-fatal stroke during 7 years of follow-up was investigated. As secondary endpoint, we investigated all-cause death. Results: Neurotensin levels did not differ between male and female patients (p = 0.560). MACE occurred in 150 (33.2%) patients. Restricted cubic splines demonstrated a U-shaped association of log-transformed neurotensin with the primary and secondary endpoint. Therefore, we dichotomized our cohort according to tertiles of log-transformed neurotensin. In Kaplan-Meier analysis including the total cohort and restricted to male patients log- neurotensin tertiles were not associated with MACE (both p > 0.05). Moreover, in the overall cohort and in male patients multivariable Cox regression analysis log-neurotensin tertiles were not associated with MACE or with all-cause death (all p > 0.05). However, in female patients log-neurotensin was associated with MACE in Kaplan-Meier analysis (log-rank p = 0.013). Also, after multivariable adjustment female patients in the first tertile had a significantly increased risk for MACE compared to female patients in the second tertile [HR 3.84 (95% CI 1.71-8.60), p = 0.001]. There was tendency for increased risk in female patients in the third tertile compared to the second tertile [HR 2.14 (95% CI 0.97-4.73), p = 0.058]. Moreover, in female patients the [first and the third tertile of log- neurotensin were associated with all-cause death 1s vs. 2nd tertile: HR 3.03 (95% CI 1.21-7.63), p = 0.018; 3rd vs. 2nd tertile: HR 3.01 (95% CI 1.22-7.44), p = 0.016]. Conclusion: In female patients with CAD undergoing PCI, neurotensin has a U-shaped relationship with adverse outcomes. These data suggest a sex specific association between neurotensin and long-term adverse events after PCI.

Edoxaban for stroke prevention in atrial fibrillation and age-adjusted predictors of clinical outcomes in routine clinical care.

AIMS: Patients with atrial fibrillation (AF) treated with oral anticoagulation still suffer from cardiovascular complications including cardiovascular death, stroke, and major bleeding. To identify risk factors for predicting stroke and bleeding outcomes in anticoagulated patients, we assessed 2-year outcomes in patients with AF treated with edoxaban in routine care. We also report the age-adjusted risk predictors of clinical outcomes. METHODS AND RESULTS: The Edoxaban Treatment in Routine Clinical Practice for Patients With Non-Valvular Atrial Fibrillation (ETNA-AF) Europe (NCT02944019) is a prospective, multi-centre, post-authorisation, observational study with an overall 4-year follow-up conducted in 825 centres enrolling edoxaban-treated patients in 10 European countries. Of the 13 133 patients with AF (mean age: 73.6 ± 9.5 years), 5682 (43.3%) were female. At the 2-year follow-up, 9017/13 133 patients were still on edoxaban; 1830 discontinued treatment including 937 who died (annualised event rate of all-cause death was 3.87%). 518 (2.14%) patients died of cardiovascular causes; 234 (0.97%) experienced major bleeding and 168 (0.70%) experienced stroke or systemic embolic events (SEE). Intracranial haemorrhage was noted in 49 patients (0.20%). History of transient ischaemic attack (TIA) at baseline was the strongest predictor of ischaemic stroke or SEE (Wald χ2: 73.63; P < 0.0001). Low kidney function at baseline was the strongest predictor of major bleeding (Wald χ2: 30.68; P < 0.0001). History of heart failure (HF) was the strongest predictor of all-cause (Wald χ2: 146.99; P < 0.0001) and cardiovascular death (Wald χ2: 100.38; P < 0.0001). CONCLUSION: Patients treated with edoxaban in ETNA-AF-Europe reported low 2-year event rates in unselected AF patients. Prior stroke, reduced kidney function, and HF identify patients at high risk of stroke, bleeding and all-cause/cardiovascular death, respectively.

Edoxaban for stroke prevention in atrial fibrillation in routine clinical care: 1-year follow-up of the prospective observational ETNA-AF-Europe study.

AIMS: Non-vitamin K oral anticoagulants are safe and effective for stroke prevention in patients with atrial fibrillation (AF). Data on the safety and efficacy of edoxaban in routine care are limited in Europe. We report 1-year outcomes in patients with AF treated with edoxaban in routine care. METHODS AND RESULTS: ETNA-AF-Europe is a prospective, multicentre, post-authorization, observational study enrolling patients treated with edoxaban in 10 European countries, the design of which was agreed with the European Medicines Agency as part of edoxaban's post-approval safety plan. Altogether 13 092 patients in 852 sites completed the 1-year follow-up [mean age: 73.6 ± 9.5 years; 57% male, mean follow-up: 352 ± 49 days (median: 366 days)]. Most patients had associated comorbidities (mean CHA2DS2-VASc score: 3.1 ± 1.4). Stroke or systemic embolism was reported in 103 patients (annualized event rate: 0.82%/year), and major bleeding events were reported in 132 patients (1.05%/year). Rates of intracranial haemorrhage were low [30 patients (0.24%/year)]. Death occurred in 442 patients (3.50%/year); cardiovascular (CV) death occurred in 206 patients (1.63%/year). The approved dosing of edoxaban was chosen in 83%. All-cause and CV mortality were higher in patients receiving edoxaban 30 mg vs. 60 mg, in line with the higher age and more frequent comorbidities of the 30 mg group. Major bleeding was also numerically more common in patients receiving edoxaban 30 mg vs. 60 mg. CONCLUSION: The rates of stroke, systemic embolism, and major bleeding are low in this large unselected cohort of high-risk AF patients routinely treated with edoxaban.

Reasons for non-vaccination against HPV and future vaccination intentions among 19-26 year-old women.

BACKGROUND: Despite CDC recommendations regarding universal catch-up vaccination against human papillomavirus (HPV), only about ten percent of young adult women in the United States have been vaccinated. The purpose of this study was to better understand reasons for non-vaccination among insured 19-26 year-old women and to evaluate future vaccination intentions. METHODS: We used an administrative claims database from a large US managed care plan to identify women aged 19-26 for receipt of a mailed survey. From a sample of 1,375 women with no evidence of HPV vaccination from June 1, 2006 through April 30, 2007, 222 completed surveys were received, of which 185 were eligible for this analysis. The main outcome measures were unvaccinated women's attitudes and vaccine awareness, likelihood of future action regarding the vaccine, and reasons for inaction. RESULTS: Among the 185 non-vaccinees, 25.4% were married, 83.2% were white, and 89.2% had a college or higher level education. The vaccine was described as very important by 32.4% of subjects, and 30.1% had discussed the vaccine with a doctor and received a doctor's recommendation. Half or fewer of respondents were "very" or "extremely" likely to discuss the vaccine with their doctor (50.0%), do additional research on the vaccine (42.6%), ask a doctor to get the vaccine (37.5%), or make an appointment to get the vaccine (27.8%), while 48.0% were "somewhat", "very", or "extremely" likely to do nothing to get the vaccine. Among the latter, reasons for taking no action included being married or in a monogamous relationship (54.9%), belief that the vaccine is too new (35.4%), not having enough information about the vaccine (31.7%), concerns about side effects (24.4%), and uncertainty about insurance coverage (24.4%). CONCLUSIONS: Educational interventions may be needed to enhance HPV vaccination rates among 19-26 year-old women, particularly regarding information about vaccine safety, vaccine efficacy, insurance coverage, and the value of vaccination to women in monogamous relationships.

Von Willebrand Factor and ADAMTS13 and long-term outcomes in patients undergoing percutaneous coronary intervention.

BACKGROUND: Von Willebrand factor (VWF) and its cleaving protease a disintegrin-like and metalloprotease with thrombospondin type I repeats 13 (ADAMTS13) are pivotal mediators of thrombosis and are associated with the progression of atherosclerosis. We investigated the impact of VWF, ADAMTS13 and VWF/ADAMTS13 on long-term major adverse cardiovascular outcomes (MACE) in patients undergoing percutaneous coronary intervention (PCI). METHODS: We analysed 701 patients undergoing PCI between 2003 and 2006. VWF and ADAMTS13 antigen levels were measured before PCI. As primary endpoint, we investigated MACE, a composite of all-cause mortality, myocardial infarction or ischemic stroke during 8 years of follow-up. As secondary endpoint, we investigated all-cause mortality. RESULTS: Mean age was 63.8 years, 496 (70.8%) were male. Acute coronary syndrome (ACS) was diagnosed in 347 (49.5%) patients, stable coronary artery disease (SCAD) in 354 (50.5%). During follow-up 228 (32.5%) patients experienced MACE, and 161 (23.0%) died. In ACS patients, VWF was significantly associated with MACE (HR 1.402 (95%CI 1.003-1.959), p = 0.048), whereas ADAMTS13 and VWF/ADAMTS13 had no predictive value. In SCAD, neither VWF, ADAMTS13, nor VWF/ADAMTS13 correlated with MACE. VWF was significantly associated with all-cause death in ACS patients (HR 1.841 (95%CI 1.187-2.856), p = 0.006), but not in SCAD (1.394 (95%CI 0.856-2.269), p = 0.181). ADAMTS13 and VWF/ADAMTS13 were not correlated with ACS and SCAD, respectively. CONCLUSION: VWF but not ADAMTS13 and VWF/ADAMTS13 was associated with MACE and mortality in patients with ACS but not SCAD. This finding highlights the importance of VWF as an essential marker of risk in patients with ACS.
