Abstract
BACKGROUND The association between coronary computed tomography angiography (CTA) derived fractional flow reserve (FFRCT) and risk of recurrent angina in patients with new onset stable angina pectoris (SAP) and stenosis by CTA is uncertain. METHODS Multicenter 3-year follow-up study of patients presenting with symptoms suggestive of new onset SAP who underwent first-line CTA evaluation and subsequent standard-of-care treatment. All patients had at least one ≥30 % coronary stenosis. A per-patient lowest FFRCT-value ≤0.80 represented an abnormal test result. Patients with FFRCT ≤0.80 who underwent revascularization were categorized according to completeness of revascularization: 1) Completely revascularized (CR-FFRCT), all vessels with FFRCT ≤0.80 revascularized; or 2) incompletely revascularized (IR-FFRCT) ≥1 vessels with FFRCT ≤0.80 non-revascularized. Recurrent angina was evaluated using the Seattle Angina Questionnaire. RESULTS Amongst 769 patients (619 [80 %] stenosis ≥50 %, 510 [66 %] FFRCT ≤0.80), 174 (23 %) reported recurrent angina at follow-up. An FFRCT ≤0.80 vs > 0.80 associated to increased risk of recurrent angina, relative risk (RR): 1.82; 95 % CI: 1.31-2.52, p < 0.001. Risk of recurrent angina in CR-FFRCT (n = 135) was similar to patients with FFRCT >0.80, 13 % vs 15 %, RR: 0.93; 95 % CI: 0.62-1.40, p = 0.72, while IR-FFRCT (n = 90) and non-revascularized patients with FFRCT ≤0.80 (n = 285) had increased risk, 37 % vs 15 % RR: 2.50; 95 % CI: 1.68-3.73, p < 0.001 and 30 % vs 15 %, RR: 2.03; 95 % CI: 1.44-2.87, p < 0.001, respectively. Use of antianginal medication was similar across study groups. CONCLUSION In patients with SAP and coronary stenosis by CTA undergoing standard-of-care guided treatment, FFRCT provides information regarding risk of recurrent angina.

Abstract
BACKGROUND Patients with gastric adenocarcinoma (GAC) are at high risk of peritoneal recurrence despite perioperative chemotherapy and radical resection. This study evaluated feasibility and safety of laparoscopic D2 gastrectomy in combination with pressurized intraperitoneal aerosol chemotherapy (PIPAC). METHODS This was a prospective, controlled bi-institutional study in patients with GAC at high risk of recurrence treated with PIPAC with cisplatin and doxorubicin (PIPAC C/D) after laparoscopic D2 gastrectomy. High risk was defined as a poorly cohesive subtype with predominance of signet-ring cells, clinical stage ≥ T3 and/or ≥ N2, or positive peritoneal cytology. Peritoneal lavage fluid was collected before and after resection. Cisplatin (10.5 mg/m2) and doxorubicin (2.1 mg/m2) were aerosolized after anastomosis (flow 0.5-0.8 ml/s, maximum pressure 300 PSI). Treatment was feasible and safe if ≤ 20% had Dindo-Clavien ≥ 3b surgical complications or CTCAE ≥ 4 medical adverse events within 30 days. Secondary outcomes were length of stay (LOS), peritoneal lavage cytology, and completion of postoperative systemic chemotherapy. RESULTS Twenty-one patients were treated with a D2 gastrectomy and PIPAC C/D. The median age was 61 years (range 24-76), there were eleven female patients, and 20 patients had preoperative chemotherapy. There was no mortality. Two patients had grade 3b complications that were potentially related to PIPAC C/D (one anastomotic leakage, and one late duodenal blow-out). One patient had severe neutropenia, and nine patients had moderate pain. The LOS was 6 days (4-26). One patient had positive peritoneal lavage cytology before resection, and none were positive after. Fifteen patients had postoperative chemotherapy. CONCLUSIONS Laparoscopic D2 gastrectomy in combination with PIPAC C/D is feasible and safe.

Abstract
BACKGROUND Pressurized Intraperitoneal Aerosol chemotherapy (PIPAC) is a local treatment for peritoneal metastasis (PM). Prospective data are scarce and evaluation of treatment response remains difficult. This study evaluated the use of the Peritoneal Regression Grading score (PRGS) and its prognostic value. PATIENTS AND METHODS This was a prospective, controlled phase II trial in patients with PM from gastrointestinal, gynaecological, hepatopancreatobiliary, primary peritoneal, or unknown primary cancer. Patients in performance status 0-1, with a non-obstructed gastrointestinal tract, and a maximum of one extraperitoneal metastasis were eligible. Colorectal or appendiceal PM had PIPAC with oxaliplatin, other primaries had PIPAC with cisplatin and doxorubicin. Biopsies were taken at each PIPAC and evaluated using the PRGS. Quality-of-life questionnaires were reported at baseline and after three PIPACs. RESULTS One hundred ten patients were treated with 336 PIPACs (median 3, range 1-12). One hundred patients had prior palliative chemotherapy and 45 patients received bidirectional treatment. Complete or major histological response to treatment (PRGS 1-2) was observed in 38 patients (61%) who had three PIPACs, which was the only independent prognostic factor in a multivariate analysis. The median overall survival (mOS) from PIPAC 1 was 10 months, while patients with PM from gastric, colorectal, and pancreatic cancer had a mOS of 7.4, 16.7, and 8.2 months, respectively. Global health scores were significantly reduced, but patients were less fatigued, nauseated, constipated, and had better appetite after three PIPACs. CONCLUSIONS PIPAC with oxaliplatin or cisplatin and doxorubicin was able to induce a major or complete histological response during three PIPACs, which may provide significant prognostic information, both at baseline and after treatment.

Abstract
PURPOSE OF REVIEW The purpose of this review is to assess the evidence for primary prevention statin treatment in older adults, within the context of the most recent guideline recommendations, while also highlighting important considerations for shared decision-making. RECENT FINDINGS As the average lifespan increases and the older adult population grows, the opportunity for prevention of morbidity and mortality from cardiovascular disease is magnified. Randomized trials and meta-analyses have demonstrated a clear benefit for primary prevention statin use through age 75, with uncertainty beyond that age. Despite these data supporting their use, current guidelines conflict in their statin treatment recommendations in those aged 70-75 years. Reflecting the paucity of evidence, the same guidelines are equivocal around primary prevention statins in those beyond age 75. Two large ongoing randomized trials (STAREE and PREVENTABLE) will provide additional insights into the treatment benefits and risks of primary prevention statins in the older adult population. In the meantime, a holistic approach in treatment decisions remains paramount for older patients. SUMMARY The benefits of primary prevention statin treatment are apparent through age 75, which is reflected in the current ACC/AHA and USPSTF recommendations. Ongoing trials will clarify the utility in those beyond age 75.

Bleeding after percutaneous coronary intervention and selection of candidates for long-term dual antithrombotic treatment. Eur Heart J 2022.

Abstract
Abstract
Background
The European Society of Cardiology recommends addition of a second antithrombotic drug (a P2Y12 inhibitor or rivaroxaban 2.5 mg twice daily) on top of aspirin in selected patients with chronic coronary syndrome (CCS) at high residual risk of ischemic events. However, this treatment increases bleeding risk, and identifying subsets of patients with the most favorable trade-off between ischemic and bleeding risk thus is essential. We hypothesized that patients undergoing percutaneous coronary intervention (PCI) who tolerate subsequent dual antiplatelet therapy (aspirin plus a P2Y12 inhibitor) without any bleeding complications selected themselves as candidates for prolonged dual antithrombotic therapy.
Methods and results
We included 30,531 patients with CCS treated with dual antiplatelet therapy after first-time PCI with a drug-eluting stent in Western Denmark (3.5 million inhabitants) from 1999 to 2018. Of these, 1,220 (4%) were hospitalized for bleeding within one year after PCI (bleeders) and 29,311 (96%) were not (non-bleeders). Patients were followed for maximum nine years (median follow-up 5.4 years). Bleeders had an increased nine-year risk of death (adjusted hazard ratio [aHR] 1.54, 95% CI 1.37–1.73) and hospitalization for bleeding (aHR 2.53, 95% CI 2.20–2.90). These associations were particularly strong for women. Looking at types of bleeding, the strongest predictors of death were gastrointestinal bleeding, cerebral bleeding, and anemia due to bleeding. Risks of myocardial infarction and ischemic stroke did not differ between bleeders and non-bleeders (Table). We then stratified non-bleeders according to their thromboembolic risk using the CHADS-P2A2RC score – a validated clinical risk prediction model developed to estimate thromboembolic risk in patients without atrial fibrillation. Non-bleeders with a high estimated thromboembolic risk (CHADS-P2A2RC score ≥4) had higher nine-year risks of myocardial infarction (hazard ratio [HR] 1.88, 95% CI 1.78–2.07), ischemic stroke (HR 3.02, 95% CI 2.66–3.43), hospitalization for bleeding (HR 1.98, 95% CI 1.81–2.16) and, in particular, death (HR 4.48, 95% CI 4.21–4.77) than non-bleeders with a low-to-moderate predicted risk (CHADS-P2A2RC score <4).
Conclusions
Patients with CCS experiencing a bleeding event during the first year after first-time PCI had a substantially higher long-term risk of death and recurrent bleeding, but not a higher risk of ischemic events. Therefore, bleeding events during the first year after PCI may guide the preclusion of selected patients from long-term dual antithrombotic therapy. Among non-bleeders, the risk of ischemic events rose proportionately more than the risk of bleeding when comparing high-risk with low-risk patients. This is an important finding for clinicians, for whom accurate identification of patients at highest risk of ischemic events is an essential step in treatment allocation.

Coronary artery disease is a stronger predictor of mortality than left ventricular ejection fraction among newly diagnosed patients with heart failure. Eur Heart J 2022.

Abstract
Abstract
Background
Heart failure (HF) prevalence remains high and prognosis is poor despite improvements in both medical treatment and implantation of primary prophylactic implantable cardioverter-defibrillator (ICD) and cardiac resynchronisation therapy (CRT) devices. At present, classification of HF and treatment algorithms are determined by the left ventricular ejection fraction (LVEF). However, in patients with LVEF <50% and newly diagnosed HF, evidence remains sparse as to whether LVEF per se or presence of CAD provide independent prognostic information on mortality.
Methods
Using the Western Denmark Heart Registry, we identified newly diagnosed patients with HF and LVEF 10–49% undergoing first-time coronary angiography (CAG) from 2003 to 2016 referred due to HF. Patients were stratified by LVEF (10–35% vs. 36–49%, according as to whether primary prophylactic ICD and CRT treatment should be considered) and presence of coronary artery disease (CAD). Maximum follow-up was 10 years. We estimated 10-year cumulative incidence of death and calculated hazard ratios (HR) adjusted for relevant comorbidities and risk factors.
Results
Of 154,186 Western Danish residents undergoing CAG, 3,620 patients had HF and LVEF 10–49%. Among these, 2,780 (77%) patients had LVEF 10–35% and 840 (23%) patients had LVEF 36–49%. CAD was present in 1,592 (44%) patients.
There was a potential association in 10-year mortality when comparing patients with HF and LVEF 36–49% to those with LVEF 10–35% (37.3% vs. 42.1%, HR 1.15; 95% CI 0.99–1.34) (Figure 1A), with point estimates of mortality ranging from being 1% reduced to 24% increased. This result was not strongly influenced by the presence of CAD (HR 1.11; 95% CI 0.91–1.35) or absence of CAD (HR 1.24; 95% CI 0.97–1.57) (Figure 1B). There was no trend between LVEF categorized by 5-percentiles and mortality (p for trend = 0.24) (Table 1). In contrast, CAD was more strongly associated with increased 10-year mortality (55.0% vs. 31.5%, HR 1.43; 95% CI 1.25–1.64) irrespective of LVEF (Figure 1B).
Conclusion
Among newly diagnosed patients with HF and LVEF 10–49%, presence of CAD impacts mortality substantially more than LVEF per se. These results emphasize that assessment of CAD is pivotal for prognostication of newly diagnosed patients with HF and LVEF 10–49%.

Influence of intensive lipid-lowering on CT derived fractional flow reserve in patients with stable chest pain: Rationale and design of the FLOWPROMOTE study. Clin Cardiol 2022; 45:986-994.

Abstract
INTRODUCTION Coronary CT angiography (CTA) derived fractional flow reserve (FFRCT ) shows high diagnostic performance when compared to invasively measured FFR. Presence and extent of low attenuation plaque density have been shown to be associated with abnormal physiology by measured FFR. Moreover, it is well established that statin therapy reduces the rate of plaque progression and results in morphology alterations underlying atherosclerosis. However, the interplay between lipid lowering treatment, plaque regression, and the coronary physiology has not previously been investigated. AIM To test whether lipid lowering therapy is associated with significant improvement in FFRCT , and whether there is a dose-response relationship between lipid lowering intensity, plaque regression, and coronary flow recovery. METHODS Investigator driven, prospective, multicenter, randomized study of patients with stable angina, coronary stenosis ≥50% determined by clinically indicated first-line CTA, and FFRCT ≤ 0.80 in whom coronary revascularization was deferred. Patients are randomized to standard (atorvastatin 40 mg daily) or intensive (rosuvastatin 40 mg + ezetimibe 10 mg daily) lipid lowering therapy for 18 months. Coronary CTA scans with blinded coronary plaque and FFRCT analyses will be repeated after 9 and 18 months. The primary endpoint is the 18-month difference in FFRCT using (1) the FFRCT value 2 cm distal to stenosis and (2) the lowest distal value in the vessel of interest. A total of 104 patients will be included in the study. CONCLUSION The results of this study will provide novel insights into the interplay between lipid lowering, and the pathophysiology in coronary artery disease.

Abstract
Abstract
Background
Married persons may have lower rates of mortality and cardiovascular disease (CV) than unmarried persons although data regarding potential differences between men and women are conflicting. The Systolic Blood Pressure Intervention Trial (SPRINT) found that intensive versus standard blood pressure (BP) control reduced CV morbidity and mortality in high-risk patients. We hypothesized that marital status would influence CV event risk and the impact of intensive BP control, and that these effects would vary according to sex.
Purpose
To assess the risks of CV events and mortality according to marital status in a high-risk population, and to assess if marital status modified the effect of intensive versus standard BP control.
Methods
SPRINT was a randomized, controlled, open-label trial of 9361 individuals at high CV risk, at least 50 years of age, without diabetes, and with a systolic BP 130–180 mmHg. Participants were randomized to either intensive or standard BP control and followed for median 3.2 years (range 0–4.8 years). The primary efficacy endpoint was the composite of acute coronary syndromes, stroke, heart failure, or CV death. Secondary efficacy endpoints included the individual components of the primary endpoint and all-cause death. Event risk according to marital status, including variation of the effects of intensive BP control, was evaluated using multivariable Cox proportional-hazards regression with interaction analyses. The group of subjects who were married or living in a marriage-like relationship served as baseline.
Results
Information on marital status was available for 8762 (93.6%) individuals. A total of 4863 (55.5%) were married or in a marriage-like relationship, 3149 (35.9%) were widowed, divorced, or separated, and 750 (8.6%) were never married. Marital status did not differ between patients randomized to intensive versus standard BP control (P=0.51). The risk of the primary endpoint was not significantly affected by marital status (P>0.05), in neither men nor women (P-interaction>0.05). The same was true for its individual components except the risk of CV death which was higher among never married men (adjusted hazard ratio [aHR], 3.29, 95% confidence interval [CI]: 1.34–8.09; P=0.009; P-sex-interaction=0.99). The risk of all-cause death was higher among widowed, divorced, or separated men (aHR, 1.90, 95% CI: 1.35–2.67; P<0.001) and among never married men (aHR, 2.53, 95% CI: 1.51–4.26; P<0.001), but not women belong to these groups (P>0.05; P-sex-interaction=0.24) (Figure). Associations were not modified by age (P-interaction>0.05). Marital status did not modify the effect of intensive BP control for any of the endpoints (P-interaction>0.05).
Conclusions
In SPRINT, never married men had higher risks of both CV death and all-cause death while widowed, divorced, or separated men had a higher risk of all-cause death. The risks and benefits of intensive BP control were not affected by marital status.

Abstract
Abstract
Background
The Systolic Blood Pressure Intervention Trial (SPRINT) found that intensive versus standard blood pressure (BP) control reduced cardiovascular (CV) morbidity and mortality in patients at high CV risk. Effects were consistent among patients with and without prevalent CV disease. However, it is unknown whether the benefits and risks of intensive BP control are affected by the specific type of heart disease.
Purpose
To assess the risks of incident CV events and safety events in patients with individual types of heart disease, and to assess if the presence of heart disease modified the effect of intensive versus standard BP control.
Methods
SPRINT was a randomized, controlled trial comprising 9,361 individuals ≥50 years of age at high CV risk, without diabetes, and with a systolic BP 130–180 mmHg. Participants were randomized to intensive or standard BP control. The primary efficacy endpoint was the composite of myocardial infarction, other acute coronary syndromes, stroke, heart failure, or death from CV causes. The primary safety endpoint was the composite of serious adverse events. We assessed event risk in patients with self-reported heart disease versus those without and further assessed the safety and efficacy of intensive BP control, including relevant interactions, in these individuals, using multivariable Cox proportional-hazards regression.
Results
Of 9361 participants, 326 (3.5%) reported a history of congestive heart failure, 760 (8.1%) of myocardial infarction, 1206 (12.9%) of angina, and 1830 (19.6%) of atrial fibrillation, atrial flutter, or irregular heartbeat. The prevalence of these conditions did not significantly differ between patients randomized to intensive versus standard BP control (P>0.05 for all). At median 3.2 years (range 0–4.8 years), congestive heart failure (adjusted hazard ratio [aHR], 1.94, 95% confidence interval [CI], 1.45–2.61; P<0.001), myocardial infarction (aHR, 1.73, 95% CI, 1.33–2.25; P<0.001), angina (aHR, 1.41, 95% CI, 1.09–1.84; P=0.01), and atrial fibrillation, atrial flutter, or irregular heartbeat (aHR, 1.36, 95% CI, 1.12–1.64; P=0.002) were all independently associated with the primary endpoint (Figure). All conditions except prior myocardial infarction were also associated with composite serious adverse events (P=0.24 for myocardial infarction, P<0.05 for all others). A history of angina modified the efficacy of intensive versus standard BP control, i.e., patients without angina appeared to benefit from intensive BP control (aHR, 0.66, 95% CI, 0.54–0.80; P<0.001) while those with angina did not (aHR, 1.04, 95% CI, 0.76–1.44; P=0.80) (P=0.02 for interaction). No significant interactions were detected for the primary safety endpoint.
Conclusions
In SPRINT, a history of any type of heart disease was associated with a greater risk for both efficacy and safety events. Patients with angina did not appear to derive benefit from intensive BP control.

Abstract
Abstract
Background
The Systolic Blood Pressure Intervention Trial (SPRINT) found that intensive versus standard blood pressure (BP) control reduced cardiovascular (CV) morbidity and mortality in high-risk patients. Although antihypertensive therapies were provided at no cost to trial participants, patients were covered by various entities. Insurance coverage provides a unique dimension of risk assessment and may provide additional prognostic information in this setting.
Purpose
To assess the risks of incident CV events and safety events in a high CV risk population according to type of health insurance, and to assess if insurance type interacted with the effect of intensive versus standard BP control.
Methods
SPRINT was a randomized, controlled trial conducted across 102 US sites of 9,361 high-risk adults ≥50 years, without diabetes, and with a systolic BP 130–180 mmHg at screening. Study participants were randomized to intensive (target systolic BP <120mmHg) or standard BP control (target systolic BP <140mmHg) and followed for median 3.2 years (range 0–4.8 years). The primary efficacy endpoint was the composite of acute coronary syndromes, stroke, heart failure, or CV death. The primary safety endpoint was the composite of serious adverse events. The risk of efficacy and safety events according to type of health insurance, including the effect of intensive BP control in each subgroup, was evaluated using multivariable Cox proportional-hazards regression with interaction analyses. Private/other insurance type served as the reference group.
Results
Of 9361 participants, 3980 (42.5%) were covered by private/other insurance, 1483 (15.8%) by a Veterans Affairs (VA) health plan, 2691 (28.8%) by Medicare, 207 (2.2%) by Medicaid, and 1000 (10.7%) were uninsured. Insurance coverage distribution was well-balanced between the two study arms (P>0.05). Compared with patients who had private/other insurance, the risk of the primary endpoint was significantly higher among Medicaid beneficiaries (adj. hazard ratio [HR], 1.81, 95% confidence interval [CI], 1.09–3.00; P=0.02). The risk of death was similarly highest among Medicaid patients (adj. HR, 2.08, 95% CI, 1.08–4.02; P=0.03) and was also significantly higher among VA patients (adj. HR, 1.49, 95% CI, 1.11–2.99; P=0.008) (Figure). Serious adverse events were more common in the VA population (HR, 1.12, 95% CI, 1.01–1.23; P=0.03). Insurance type did not modify the efficacy and safety of intensive BP control (P>0.05 for all interactions).
Conclusions
In SPRINT, Medicaid beneficiaries were at significantly greater risk for experiencing a primary CV event. Medicaid patients and VA patients both had higher mortality than those covered by private/other insurance. The risks and benefits of intensive BP control were not affected by insurance type.

Clinical outcomes following real-world computed tomography angiography-derived fractional flow reserve testing in chronic coronary syndrome patients with calcification. Eur Heart J Cardiovasc Imaging 2021; 22:1182-1189. [PMID: 32793947 DOI: 10.1093/ehjci/jeaa173] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2020] [Revised: 03/23/2020] [Accepted: 05/29/2020] [Indexed: 11/13/2022] Open
Abstract
AIMS This study sought to investigate outcomes following a normal CT-derived fractional flow reserve (FFRCT) result in patients with moderate stenosis and coronary artery calcification, and to describe the relationship between the extent of calcification, stenosis, and FFRCT. METHODS AND RESULTS Data from 975 consecutive patients suspected of chronic coronary syndrome with stenosis (30-70%) determined by computed CT angiography and FFRCT to guide downstream management decisions were reviewed. Median (range) follow-up time was 2.2 (0.5-4.2) years. Coronary artery calcium (CAC) scores were ≥400 in 25%, stenosis ≥50% in 83%, and FFRCT >0.80 in 51% of the patients. There was a lower incidence of the composite endpoint (death, myocardial infarction, hospitalization for unstable angina, and unplanned coronary revascularization) at 4.2 years in patients with any CAC and FFRCT > 0.80 vs. FFRCT ≤ 0.80 (3.9% and 8.7%, P = 0.04), however, in patients with CAC scores ≥400 the risk difference between groups did not reach statistical significance, 4.2% vs. 9.7% (P = 0.24). A negative relationship between CAC scores and FFRCT irrespective of stenosis severity was demonstrated. CONCLUSION FFRCT shows promise in identifying patients with stenosis and calcification who can be managed without further downstream testing. Moreover, an inverse relationship between CAC levels and FFRCT was demonstrated. Studies are needed to further assess the clinical utility of FFRCT in patients with extensive coronary calcification.

Reduction of Myocardial Infarction and All-Cause Mortality Associated to Statins in Patients Without Obstructive CAD. JACC Cardiovasc Imaging 2021; 14:2400-2410. [PMID: 34274285 DOI: 10.1016/j.jcmg.2021.05.022] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Accepted: 05/07/2021] [Indexed: 01/16/2023]
Abstract
OBJECTIVE The aim of this work was to evaluate the prognostic impact of statin therapy in symptomatic patients without obstructive CAD. BACKGROUND Information on the prognostic impact of post-coronary computed tomographic angiography (CTA) statin use in patients with no or nonobstructive coronary artery disease (CAD) is sparse. METHODS Patients undergoing CTA with suspected CAD in western Denmark from 2008 to 2017 with <50% coronary stenoses were identified. Information on post-CTA use of statin therapy and cardiovascular events were obtained from national registries. RESULTS The study included 33,552 patients, median aged 56 years, 58% female, with no (n = 19,669) or nonobstructive (n = 13,883) CAD and a median follow-up of 3.5 years. The absolute risk of the combined end point of myocardial infarction (MI) or all-cause mortality was directly associated with the CAD burden with an event rate/1,000 patient-years of 4.13 (95% CI: 3.69-4.61) in no, 7.74 (95% CI: 6.88-8.71) in mild (coronary artery calcium score [CACS] 0-99), 13.72 (95% CI: 11.61-16.23) in moderate (CACS 100-399), and 32.47 (95% CI: 26.25-40.16) in severe (CACS ≥400) nonobstructive CAD. Statin therapy was associated with a multivariable adjusted HR for MI and death of 0.52 (95% CI: 0.36-0.75) in no, 0.44 (95% CI: 0.32-0.62) in mild, 0.51 (95% CI: 0.34-0.75) in moderate, and 0.52 (95% CI: 0.32-0.86) in severe nonobstructive CAD. The estimated numbers needed to treat to prevent the primary end point were 92 (95% CI: 61-182) in no, 36 (95% CI: 26-58) in mild, 24 (95% CI: 15-61) in moderate, and 13 (95% CI: 7-86) in severe nonobstructive CAD. Residual confounding may persist, but not to an extent explaining all of the observed risk reduction associated with statin treatment. CONCLUSIONS The risk of MI and all-cause mortality in patients without obstructive CAD is directly associated with the CAD burden. Statin therapy is associated with a reduction of MI and all-cause death across the spectrum of CAD, however, the absolute benefit of treatment is directionally proportional with the CAD burden.

Abstract
This research letter describes unexpected and unacceptable local toxicity manifesting as abdominal pain after adjuvant pressurized intraperitoneal aerosol chemotherapy with 92 mg/m2 oxaliplatin in the PIPAC-OPC3 study. It is not clear whether the toxicity is dose- or drug-dependent (or both), but the preliminary data suggest that tolerability is improved by dose reduction to 46 mg/m2.

Abstract
BACKGROUND Most patients undergo follow-up after surgery for cancers of the gastro-oesophageal junction, stomach or pancreas, but data to support which modalities to use and the frequency of investigation are limited. METHODS Patients in the EUFURO study were randomized to either visits to the outpatient clinic at 3, 6, 9, 12, 18, and 24 months after surgery (standard), or to the addition of [18F]fluorodeoxyglucose (FDG) PET-CT and endoscopic ultrasonography (EUS) with guided fine-needle aspiration biopsy to clinical assessments (intervention). Data from the intervention arm were used to analyse the diagnostic performance of endosonography or [18F]FDG PET-CT in detecting recurrences. RESULTS During the scheduled follow-up, 42 of 89 patients developed recurrence; PET-CT and EUS in combination detected 38 of these recurrences. EUS detected 23 of the 42 patients with recurrent disease during follow-up and correctly diagnosed 17 of 19 locoregional recurrences. EUS was able to detect isolated locoregional recurrence in 11 of 13 patients. In five patients, EUS was false-positive for isolated locoregional recurrence owing to missed distant metastases. PET-CT detected locoregional recurrence in only 12 of 19 patients, and isolated locoregional recurrence in only 7 of 13. False-positive PET-CT results in 23 patients led to a total of 44 futile procedures. CONCLUSION Accuracy in detecting recurrences by concomitant use of PET-CT and EUS was high (90 per cent). PET-CT had moderate to high sensitivity for overall recurrence detection, but low specificity. EUS was superior to PET-CT in the detection of locoregional and isolated locoregional recurrences.

Abstract
INTRODUCTION Numerous studies have shown that lowering of low-density lipoprotein-cholesterol (LDL-C) reduces the risk of cardiovascular disease (CVD). To optimise treatment, some patients are referred to a lipid clinic. The reduction in LDL-C achieved in a lipid clinic in contemporary practice is, however, not well described. The aim of the present study was to assess the LDL-C lowering effect among very high-risk patients with or without statin-associated muscle symptoms (SAMS) after treatment at a specialised lipid clinic endorsing European guidelines. METHODS Medical records from 653 patients referred to our Lipid Clinic from 1 January 2013 to 1 May 2017 were examined retrospectively. Very high-risk patients were defined as either having CVD or diabetes mellitus Type 2 who were active smokers and/or had hypertension. The reduction in LDL-C and the number of patients reaching the LDL-C treatment target were investigated by comparing baseline data with the most recent values recorded. RESULTS We identified 208 patients at a very high-risk for CVD. They obtained an LDL-C reduction of 23% corresponding to a reduction in LDL-C of 0.7 mmol/l (p less than 0.001). The percentage of patients reaching their LDL-C goal increased from 13% to 32%. In patients who had experienced SAMS, LDL-C was reduced by 26% corresponding to a reduction in LDL-C of 0.9 mmol/l (p less than 0.001), and the percentage of patients reaching their LDL-C goal increased from 8% to 23%. CONCLUSIONS Very high-risk patients with or without SAMS obtained a clinically meaningful reduction in LDL-C of approximately 25% owing to their Lipid Clinic treatment. FUNDING none.

Intraoperative ultrasound imaging in the surgical treatment of congenital hyperinsulinism: prospective, blinded study. BJS Open 2020; 5:5973900.

Abstract
Background In congenital hyperinsulinism (CHI), preoperative prediction of the histological subtype (focal, diffuse, or atypical) relies on genetics and 6-[18F]fluoro-l-3,4-dihydroxyphenylalanine (18F-DOPA) PET–CT. The scan also guides the localization of a potential focal lesion along with perioperative frozen sections. Intraoperative decision-making is still challenging. This study aimed to describe the characteristics and potential clinical impact of intraoperative ultrasound imaging (IOUS) during CHI surgery. Methods This was a prospective, observational study undertaken at an expert centre over a 2-year interval. IOUS was performed blinded to preoperative diagnostic test results (genetics and 18F-DOPA PET–CT), followed by unblinding and continued IOUS during pancreatic resection. Characteristics and clinical impact were assessed using predefined criteria. Results Eighteen consecutive, surgically treated patients with CHI, with a median age of 5.5 months, were included (focal 12, diffuse 3, atypical 3). Focal lesions presented as predominantly hypoechoic, oval lesions with demarcated or blurred margins. Patients with diffuse and atypical disease had varying echogenicity featuring stranding and non-shadowing hyperechoic foci in three of six, whereas these characteristics were absent from those with focal lesions. The blinded IOUS-based subclassification was correct in 17 of 18 patients; one diffuse lesion was misclassified as focal. IOUS had an impact on the surgical approach in most patients with focal lesions (9 of 12), and in those with diffuse (2 of 3) and atypical (2 of 3) disease when the resection site was close to the bile or pancreatic duct. Conclusion Uniform IOUS characteristics made all focal lesions identifiable. IOUS had a clinical impact in 13 of 18 patients by being a useful real-time supplementary modality in terms of localizing focal lesions, reducing the need for frozen sections, and preserving healthy tissue and delicate structures.

Abstract
Self-expandable metallic stent (SEMS) is a preferred option to relieve dysphagia and to palliate patients with incurable esophageal or gastro-esophageal junction (GEJ) cancer. Health Related Quality of Life (QoL) represents a clinically relevant outcome measure in research focused on palliation of patients with advanced GI cancer. In this context, home visits by a nurse carry the potential to offer important advantages. Eighty patients with incurable esophageal or GEJ cancer were randomized to either standard follow up or to an intervention containing regular home visits by a nurse. The primary outcome variable QoL was assessed by EORTC QLQ-C30 and OES-18 before insertion of SEMS, and at 2, 7 and 12 weeks thereafter. Secondary outcomes were; need for re-interventions, number of patients receiving palliative oncological therapy and overall survival. Sixty-six males and 13 females, with a median age of 71, were included. Self-reported overall QoL was significantly higher in the intervention group (P = 0.03). The organ specific module OES-18 revealed a significant reduction in dysphagia by the intervention (P = 0.03) as well as fewer eating disabilities (P = 0.04). No differences were observed in secondary outcomes except for overall survival, where the median survival was increased from 114 to 183 days by the active intervention (P = 0.02). Home visits by a nurse seem to play an important palliative role after placement of SEMS in patients with incurable esophageal or GEJ cancer by improving QoL and may carry the potential to increase overall survival.

Abstract
Background Coronary artery calcium (CAC) is a predictor for the development of cardiovascular disease (CVD) and to a lesser extent cancer. The age‐ and sex‐specific relationship of CAC with CVD and cancer mortality is unknown. Methods and Results Asymptomatic patients aged 40 to 75 years old without known CVD were included from the CAC Consortium. We calculated sex‐specific mortality rates per 1000 person‐years’ follow‐up. Using parametric survival regression modeling, we determined the age‐ and sex‐specific CAC score at which the risk of death from CVD and cancer were equal. Among the 59 502 patients included in this analysis, the mean age was 54.9 (±8.5) years, 34% were women, and 89% were white. There were 671 deaths attributable to CVD and 954 deaths attributable to cancer over a mean follow‐up of 12±3 years. Among patients with CAC=0, cancer was the leading cause of death, the total mortality rate was low (women, 1.8; men, 1.5), and the CVD mortality rate was exceedingly low for women (0.3) and men (0.3). The age‐specific CAC score at which the risk of CVD and cancer mortality were equal had a U‐shaped relationship for women, while the relationship was exponential for men. Conclusions The age‐ and sex‐specific relationship of CAC with CVD and cancer mortality differed significantly for women and men. Our age‐ and sex‐specific CAC score provides a more precise estimate and further facilitates the use of CAC as a synergistic tool in strategies for the prediction and prevention of CVD and cancer mortality.

Trends in antidiabetic drug utilization and expenditure in Denmark: A 22-year nationwide study. Diabetes Obes Metab 2020; 22:167-172.

Abstract
AIMS To examine the nationwide trends in antidiabetic drug utilization and expenditure in Denmark over the past 22 years. METHODS Data on antidiabetic use and expenditure from 1996 to 2017 were retrieved from the Register of Medicinal Product Statistics. Antidiabetic drug use is reported as defined daily dose (DDD) in total counts and per 1000 inhabitants/d. Expenditure is reported as volume sold in total counts per 1000 inhabitants and as annual mean expenditure. RESULTS Throughout the study period, the total use of antidiabetic drugs increased from 16.4 to 55.8 DDDs per 1000 inhabitants/d, while total expenditure increased from €59 to €286 m. The introduction of glucagon-like peptide-1 receptor agonists (GLP-1RAs), dipeptidyl peptidase-4 inhibitors and sodium-glucose co-transporter-2 inhibitors has, since 2005, led to considerable variation in the proportional use of the different drug classes. Use of insulin and insulin analogues accounted for the majority of the cost of antidiabetic drugs, peaking at 75% in 2008; however, its proportional impact on overall antidiabetic drug expenditure decreased to ~44% in 2017. In contrast, a steep increase in GLP-1RA expenditure was observed from 2010 to 2017, reaching an annual cost of €85 m (~29% of all antidiabetic expenditure). CONCLUSION Antidiabetic drug utilization and cost in Denmark has increased considerably over the last 22 years, in accordance with the increased incidence of type 2 diabetes and changes in treatment guidelines. The release of several novel antidiabetic drugs seems to be responsible for the increase in antidiabetic drug expenditure.

Abstract
Pressurized intraperitoneal aerosol chemotherapy (PIPAC) represents a novel approach to deliver intraperitoneal chemotherapy. We report our experience with PIPAC in patients with peritoneal metastasis (PM) from gastric cancer (GC). Data from GC patients (n = 20) included in the prospective PIPAC-OPC1 and PIPAC-OPC2 studies are reported. All patients had received prior systemic chemotherapy. The mean peritoneal cancer index (PCI) was 10.5 (range 0-39) and nine patients had diffuse GC. PIPAC with cisplatin 7.5 mg/m2 and doxorubicin 1.5 mg/m2 were administered at 4-6-week intervals. Outcome criteria were objective tumour response, survival and adverse events. Twenty patients had 52 PIPAC procedures with a median follow-up of 10.4 months (3.3-26.5). Median survival from the time of PM diagnosis and after the first PIPAC procedure was 11.5 months and 4.7 months, respectively. Fourteen patients had repeated PIPAC (> 2), and the objective tumour response according to the histological peritoneal regression grading score (PRGS) was observed in 36%, whereas 36% had stable disease. Ten patients completed the three prescheduled sessions (per protocol group) and 40% of those displayed an objective tumour response, while 20% had stable disease. Only minor postoperative complications were noted, and none were considered causally related to the PIPAC treatment. PIPAC with low-dose cisplatin and doxorubicin can induce a quantifiable objective tumour response in selected patients with PM from GC. Survival data are encouraging and warrant further clinical studies.

Abstract
Abstract
Background
Upper gastrointestinal malignancies have a poor prognosis. There is no consensus on how patients should be followed after surgery. The authors hypothesized that a structured follow-up programme including endoscopic ultrasonography (EUS) and [18F]fluorodeoxyglucose (FDG) PET/CT would detect cancer recurrences, leading to more patients being eligible for therapy.
Methods
After surgery with curative intent for adenocarcinomas in the gastro-oesophageal junction, stomach or pancreas, patients were randomized 1 : 1 to standard clinical assessment in the outpatient clinic at 3, 6, 9, 12, 18 and 24 months after operation, or clinical assessment plus imaging including [18F]FDG PET/CT and EUS. The primary endpoint was number of patients receiving oncological treatment for recurrence. Secondary endpoints were overall and progression-free survival, survival after recurrence detection of isolated locoregional recurrences and risk factors affecting survival.
Results
In total, 183 patients were enrolled, including 93 who underwent standard follow-up and 90 who had follow-up plus imaging. A recurrence was detected in 84 patients within 2 years after surgery (42 in each group), including 33 of 42 patients in the imaging group who were asymptomatic. Some 25 of 42 patients in the imaging group and 14 of 42 in the standard group received chemotherapy (P = 0·028). Although survival after detection of recurrence in asymptomatic patients was significantly longer than that for symptomatic patients (P < 0·001), overall survival from date of surgery in the two treatment groups was comparable.
Conclusion
Follow-up after surgery for upper gastrointestinal cancer with EUS and PET/CT leads to detection of more asymptomatic cancer recurrences and patients referred for treatment without prolonging overall survival. Registration number: NCT02209415 (http://www.clinicaltrials.gov).

Abstract
Abstract
Introduction: High systemic inflammation and low levels of exercise are associated with increased risk of cancer. We hypothesized that in the setting of inflammation, exercise mitigates cancer risk.
Methods: To address this, we identified 6,388 participants, free of cancer and cardiovascular disease, enrolled in the Multi-Ethnic Study of Atherosclerosis. Regular moderate/vigorous intentional exercise was categorized as present or absent based on self-report from validated questions. A composite inflammatory score was created with a point given for C-reactive protein, IL-6, fibrinogen, and GlycA above normal, with composite scores > 2 points categorized as high. Cancer incidence was ascertained based on ICD codes abstracted from hospitalization or cancer registry data. Cox proportional hazard models were used to calculate subsequent risk of incident cancer. Models were adjusted for baseline age, gender, race, pack years smoking, education, income, health insurance status, body mass index, high-density lipoprotein levels, healthy diet adherence, statin and aspirin use.
Results: The mean age was 62 years (±10.2 years), 53% female, 39% white, 26% black, 22% Hispanic, and 12% Chinese-American. Compared to the reference group (individuals reporting no exercise and with low levels of inflammation), in multi-variable adjusted models, individuals with high levels of inflammation and no exercise were at highest risk of cancer (hazard ratio = 1.17; 95% confidence interval 1.00 – 1.37), while those with low levels of inflammation who exercised were at the lowest risk of cancer (HR 0.80, 95% CI 0.68-0.95). Those who had high levels of inflammation, but regular exercise had no increased risk of cancer (HR 0.94, 95% CI 0.68-1.30). There was no significant interaction between exercise and inflammation. When considering individual inflammatory markers, there was a similar pattern (Table).
Conclusion: Intentional moderate/vigorous exercise may lower the risk of cancer in individuals with high versus low levels of chronic inflammation.

[PMID: 30830974 DOI: 10.1002/bjs.11093] [Citation(s) in RCA: 41] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2018] [Revised: 10/09/2018] [Accepted: 11/26/2018] [Indexed: 01/08/2023]
Abstract
BACKGROUND Multidisciplinary team (MDT) meetings have been adopted widely to ensure optimal treatment for patients with cancer. Agreements in tumour staging, resectability assessments and treatment allocation between different MDTs were assessed. METHODS Of all patients referred to one hospital, 19 patients considered to have non-metastatic pancreatic cancer for evaluation were selected randomly for a multicentre study of MDT decisions in seven units across Northern Europe. Anonymized clinical information and radiological images were disseminated to the MDTs. All patients were reviewed by the MDTs for radiological T, N and M category, resectability assessment and treatment allocation. Each MDT was blinded to the decisions of other teams. Agreements were expressed as raw percentages and Krippendorff's α values, both with 95 per cent confidence intervals. RESULTS A total of 132 evaluations in 19 patients were carried out by the seven MDTs (1 evaluation was excluded owing to technical problems). The level of agreement for T, N and M categories ranged from moderate to near perfect (46·8, 61·1 and 82·8 per cent respectively), but there was substantial variation in assessment of resectability; seven patients were considered to be resectable by one MDT but unresectable by another. The MDTs all agreed on either a curative or palliative strategy in less than half of the patients (9 of 19). Only fair agreement in treatment allocation was observed (Krippendorff's α 0·31, 95 per cent c.i. 0·16 to 0·45). There was a high level of agreement in treatment allocation where resectability assessments were concordant. CONCLUSION Considerable disparities in MDT evaluations of patients with pancreatic cancer exist, including substantial variation in resectability assessments.

Severe peritoneal sclerosis after repeated pressurized intraperitoneal aerosol chemotherapy with oxaliplatin (PIPAC OX): report of two cases and literature survey. Clin Exp Metastasis 2018; 35:103-108. [PMID: 29705882 DOI: 10.1007/s10585-018-9895-9] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2018] [Accepted: 04/23/2018] [Indexed: 01/12/2023]
Abstract
Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a new laparoscopic administration of chemotherapy for peritoneal metastasis (PM). PIPAC is repeated every 5th week, and seems to stabilize or improve quality of life, and might improve survival. So far, PIPAC has been well tolerated. With this paper, we aim to highlight a potential severe adverse reaction, as we describe the first cases of severe peritoneal sclerosis (SPS) caused by PIPAC. Patients with isolated PM were included in a prospective PIPAC protocol. Following insufflation of normothermic CO2, laparoscopy was performed at an intraabdominal pressure of 12 mmHg. After peritoneal lavage and quadrant biopsies of the PM, the patients were treated with oxaliplatin 92 mg/m2 (flowrate 0.5 ml/s, maximum pressure of 200 per square inch). Treatment related toxicity was evaluated after 2 weeks. Response was evaluated histologically by the Peritoneal Regression Grading Score (PRGS) and cytologically by analysis of the lavage fluid. In a series of 24 PIPAC patients treated with oxaliplatin, two patients developed SPS. Patient one had a mucinous adenocarcinoma of the appendix with PM, the mean PRGS was reduced from 2.75 to 1.75 during the course of therapy. Patient two had an appendiceal goblet cell carcinoid with a dominating mucinous adenocarcinoma component with PM, the mean PRGS was reduced from 2.00 to 1.67. Repeated applications of PIPAC with oxaliplatin can lead to SPS.

Kringle IV Type 2, Not Low Lipoprotein(a), as a Cause of Diabetes: A Novel Genetic Approach Using SNPs Associated Selectively with Lipoprotein(a) Concentrations or with Kringle IV Type 2 Repeats. Clin Chem 2017; 63:1866-1876. [PMID: 28971985 DOI: 10.1373/clinchem.2017.277103] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2017] [Accepted: 08/15/2017] [Indexed: 11/06/2022]
Abstract
BACKGROUND Low plasma lipoprotein(a) concentrations are associated with type 2 diabetes. Whether this is due to low lipoprotein(a) concentrations per se or to a large number of kringle IV type 2 (KIV-2) repeats remains unclear. We therefore aimed to identify genetic variants associated selectively with lipoprotein(a) concentrations or with the number of KIV-2 repeats, to investigate which of these traits confer risk of diabetes. METHODS We genotyped 8411 individuals from the Copenhagen City Heart Study for 778 single-nucleotide polymorphisms (SNPs) in the proximity of the LPA gene, and examined the association of these SNPs with plasma concentrations of lipoprotein(a) and with KIV-2 number of repeats. SNPs that were selectively associated with lipoprotein(a) concentrations but not with KIV-2 number of repeats, or vice versa, were included in a Mendelian randomization study. RESULTS We identified 3 SNPs (rs12209517, rs12194138, and rs641990) that were associated selectively with lipoprotein(a) concentrations and 3 SNPs (rs1084651, rs9458009, and rs9365166) that were associated selectively with KIV-2 number of repeats. For SNPs selectively associated with lipoprotein(a) concentrations, an allele score of 4-6 vs 0-2 had an odds ratio for type 2 diabetes of 1.03 (95% CI, 0.86-1.23). In contrast, for SNPs selectively associated with KIV-2 number of repeats, an allele score of 4-6 vs 0-2 had an odds ratio for type 2 diabetes of 1.42 (95% CI, 1.17-1.69). CONCLUSIONS Using a novel genetic approach, our results indicate that it is a high number of KIV-2 repeats that are associated causally with increased risk of type 2 diabetes, and not low lipoprotein(a) concentrations per se. This is a reassuring finding for lipoprotein(a)-lowering therapies that do not increase the KIV-2 number of repeats.

Randomized clinical trial of laparoscopic ultrasonography before laparoscopic colorectal cancer resection. Br J Surg 2017; 104:1462-1469.

Abstract
BACKGROUND Intraoperative ultrasonography during open surgery for colorectal cancer may be useful for the detection of unrecognized liver metastases. Laparoscopic ultrasonography (LUS) for the detection of unrecognized liver metastasis has not been studied in a randomized trial. This RCT tested the hypothesis that LUS would change the TNM stage and treatment strategy. METHODS Patients with colorectal cancer and no known metastases were randomized (1 : 1) to laparoscopic examination (control or laparoscopy plus LUS) in three Danish centres. Neither participants nor staff were blinded to the group assignment. RESULTS Three hundred patients were randomized, 150 in each group. After randomization, 43 patients were excluded, leaving 128 in the control group and 129 in the LUS group. Intraoperative T and N categories were not altered by LUS, but laparoscopy alone identified previously undetected M1 disease in one patient (0·8 per cent) in the control group and three (2·3 per cent) in the LUS group. In the latter group, LUS suggested that an additional six patients (4·7 per cent) had M1 disease with liver (4) or para-aortal lymph node (2) metastases. The change in treatment strategy was greater in the LUS than in the control group (7·8 (95 per cent c.i. 3·8 to 13·8) and 0·8 (0 to 4·2) per cent respectively; P = 0·010), but the suspected M1 disease was benign in half of the patients. CONCLUSION Routine LUS during resection of colorectal cancer is not recommended. Registration number: NCT02079389 (http://www.clinicaltrials.gov).

Primary Prevention With Statins: ACC/AHA Risk-Based Approach Versus Trial-Based Approaches to Guide Statin Therapy. J Am Coll Cardiol 2016; 66:2699-2709.

Abstract
BACKGROUND Guidelines recommend initiating primary prevention for atherosclerotic cardiovascular disease (ASCVD) with statins based on absolute ASCVD risk assessment. Recently, alternative trial-based and hybrid approaches were suggested for statin treatment eligibility. OBJECTIVES This study compared these approaches in a direct head-to-head fashion in a contemporary population. METHODS The study used the CGPS (Copenhagen General Population Study) with 37,892 subjects aged 40 to 75 years recruited in 2003 to 2008, all free of ASCVD, diabetes, and statin use at baseline. RESULTS Among the population studied, 42% were eligible for statin therapy according to the 2013 American College of Cardiology/American Heart Association (ACC/AHA) risk assessment and cholesterol treatment guidelines approach, versus 56% with the trial-based approach and 21% with the hybrid approach. Among these statin-eligible subjects, the ASCVD event rate per 1,000 person-years was 9.8, 6.8, and 11.2, respectively. The ACC/AHA-recommended absolute risk score was well calibrated around the 7.5% 10-year ASCVD risk treatment threshold and discriminated better than the trial-based or hybrid approaches. Compared with the ACC/AHA risk-based approach, the net reclassification index for eligibility for statin therapy among 40- to 75-year-old subjects from the CGPS was -0.21 for the trial-based approach and -0.13 for the hybrid approach. CONCLUSIONS The clinical performance of the ACC/AHA risk-based approach for primary prevention of ASCVD with statins was superior to the trial-based and hybrid approaches. Our results indicate that the ACC/AHA guidelines will prevent more ASCVD events than the trial-based and hybrid approaches, while treating fewer people compared with the trial-based approach.

Abstract
Abstract
Objective: To investigate the effect of local steroid administration on seroma formation until 14 days of dryness.
Background: Seroma formation, the most prevalent postoperative complication after mastectomy, is an inflammatory process that is potentially preventable via local steroid administration.
Methods: This double-blind, randomized, placebo-controlled intervention study included 212 women who were scheduled for mastectomy for primary breast cancer. The patients were classified according to the surgical axillary procedure: mastectomy with sentinel lymph node biopsy (M+SLNB) or mastectomy with level I-II axillary lymph node dissection (M+ALND). The participants received either 80 mg of methylprednisolone or saline intracavitary via the drain orifice upon drain removal.
Results: After M+SLNB, 46% (32 of 69) of the patients developed seromas in the steroid group vs. 78% (52 of 67) in the saline group (p<0.0001). The mean cumulative seroma volume in the intention-to-treat material for the first 10 and 30 days was significantly lower in the steroid group than in the saline group (24 vs.127 mL and 177 vs. 328 mL, respectively) (p<0.0001). After M+ALND, 94% of the patients developed seromas in both the steroid (35 of 37) and saline (34 of 36) groups, and steroid administration displayed no significant effect on seroma formation. Additionally, no difference in the infection rate was observed.
Conclusion: Methylprednisolone administered intracavitary on the first postoperative day after M+SLNB exerted a highly significant preventive effect against seroma formation during the first 30 days. Future studies may clarify whether higher or repeated steroid doses enhance these effects.

Diabetes with poor glycaemic control does not promote atherosclerosis in genetically modified hypercholesterolaemic minipigs. Diabetologia 2015; 58:1926-36.

Abstract
AIMS/HYPOTHESIS Diabetes is associated with an increased risk of atherosclerotic cardiovascular disease, but whether there is a direct and independent role for impaired glucose control in atherogenesis remains uncertain. We investigated whether diabetes with poor glycaemic control would accelerate atherogenesis in a novel pig model of atherosclerosis, the D374Y-PCSK9(+) transgenic minipig. METHODS Nineteen minipigs were fed a cholesterol-enriched, high-fat diet; ten of these pigs were injected with streptozotocin to generate a model of diabetes. Restricted feeding was implemented to control the pigs' weight gain and cholesterol intake. After 49 weeks of high-fat feeding, the major arteries were harvested for a detailed analysis of the plaque burden and histological plaque type. RESULTS Stable hyperglycaemia was achieved in the diabetic minipigs, while the plasma total and LDL-cholesterol and creatinine levels were unaffected. Diabetes failed to increase atherosclerosis in any of the vessels examined. The plaque burden in the aorta and right coronary artery was comparable between the groups, and was even reduced in the left anterior descending (LAD) coronary and iliofemoral arteries in the diabetic pigs compared with the controls. The distribution of plaque types and the collagen and macrophage contents were similar between the groups, except for a reduced infiltration of macrophages in the LAD arteries of the diabetic pigs. CONCLUSIONS/INTERPRETATION Poorly controlled diabetes with no alterations in plasma cholesterol or creatinine concentrations did not augment the plaque burden or promote the development of more advanced lesions in this large-animal model of human-like atherosclerosis. This is consistent with clinical studies in patients with type 1 diabetes, indicating that hyperglycaemia per se is not an independent promoter of atherosclerotic disease, but that other diabetes-associated risk factors are important.

The high-density lipoprotein-adjusted SCORE model worsens SCORE-based risk classification in a contemporary population of 30,824 Europeans: the Copenhagen General Population Study. Eur Heart J 2015; 36:2446-53.

Abstract
Aims Recent European guidelines recommend to include high-density lipoprotein (HDL) cholesterol in risk assessment for primary prevention of cardiovascular disease (CVD), using a SCORE-based risk model (SCORE-HDL). We compared the predictive performance of SCORE-HDL with SCORE in an independent, contemporary, ‘low-risk’ European population, focusing on ability to identify those in need of intensified CVD prevention. Methods and results Between 2003 and 2008, 46 092 individuals without CVD, diabetes, or statin use were enrolled in the Copenhagen General Population Study (CGPS). During a mean of 6.8 years of follow-up, 339 individuals died of CVD. In the SCORE target population (age 40–65; n = 30 824), fewer individuals were at baseline categorized as high risk (≥5% 10-year risk of fatal CVD) using SCORE-HDL compared with SCORE (10 vs. 17% in men, 1 vs. 3% in women). SCORE-HDL did not improve discrimination of future fatal CVD, compared with SCORE, but decreased the detection rate (sensitivity) of the 5% high-risk threshold from 42 to 26%, yielding a negative net reclassification index (NRI) of −12%. Importantly, using SCORE-HDL, the sensitivity was zero among women. Both SCORE and SCORE-HDL overestimated risk of fatal CVD. In well-calibrated models developed from the CGPS, HDL did not improve discrimination or NRI. Lowering the decision threshold from 5 to 1% led to progressive gain in NRI for both CVD mortality and morbidity. Conclusion SCORE-HDL did not improve discrimination compared with SCORE, but deteriorated risk classification based on NRI. Future guidelines should consider lower decision thresholds and prioritize CVD morbidity and people above age 65.

Abstract
Background:
Individuals with type 1 diabetes mellitus (T1DM) are at high risk of developing atherosclerotic cardiovascular disease but the exact mechanisms by which T1DM accelerates atherosclerosis remain unknown. In the present study, we investigated whether modifications of low density lipoprotein (LDL) in T1DM patients causes an increased retention of LDL in the vessel wall.
Methods and Results:
Fluorescently-labeled human LDL from either T1DM patients (n=10) or healthy non-diabetic subjects (control) (n=7) was injected into mice with T1DM. After 24 hours, when LDL was completely cleared from the circulation, cryosections of the inner curvature of the aortic arch (i.e. atherosclerosis prone area) was analyzed for retained LDL by fluorescence microscopy (Red in figure A). We found significantly more retained T1DM LDL (n=10) compared to LDL from non-diabetic subjects (n=7) with a fold change of 4.35 (p < 0.05). Nuclear magnetic resonance (NMR) spectroscopy analysis of LDL revealed no differences in the level of the atherogenic small dense LDL between T1DM LDL (274.4±47.8 nmol/L) and non-diabetic LDL (263.8±55.3 nmol/L). Using LiCor Odyssey infrared imaging scanning of the whole aorta en face, we found that in vitro glycation of LDL from a non-diabetic subject significantly increased retention (n=8) compared to LDL prepared similarly but without glucose (n=8), with a fold change of 8.87 (p < 0.001) (Figure B).
Conclusion:
LDL from patients with T1DM as well as ex vivo glycated LDL showed increased retention at atherosclerosis-prone sites in the arterial wall of mice. This may contribute to the accelerated development of atherosclerosis in T1DM.

Abstract
INTRODUCTION Primary duodenal carcinoma (PDC) is a rare gastrointestinal tumor. The difficult distinction between PDC and other types of carcinoma (e.g. within the periampullary region) is reflected in the scarce literature on true duodenal carcinomas. However, this distinction may be important in relation to the overall prognosis as well as in the choice of adjuvant or palliative treatment strategies. The aim of this study was to evaluate the incidence, management and prognosis of patients with true PDC within a well-defined geographical area. METHODS Retrospective analysis of all patients diagnosed with true PDC from 1997 to 2012 within the Region of Southern Denmark. Only patients where the surgeon and the pathologist agreed on the tumor being classified as originating from the duodenum were included. RESULTS Seventy-one patients (43 M, 28 F) with a mean age of 67 years (range 35-87) met the criteria for true PDC. The incidence was 5.4 per 1,000,000, and the pathological classification was: Adenocarcinoma 87%, mucinous adenocarcinoma 7%, carcinoma 4% and signet ring cell carcinoma 1%. Intended curative resection was performed in 28 patients (39%) (22 Whipple procedures and 6 local resections), and all but one patient had negative resection margins. Thirteen patients (46%) had lymph node metastasis. Twenty-nine (67%) of the palliative treated patients had a single (n = 24) or double by-pass procedure (n = 5). The median and 5-year survival for the resected patients were 23 months (CI 7-44) and 27% (CI 10-44). The median survival in the palliative group was 5 months (CI 2-11), and none of the patients were alive after three years. CONCLUSION The incidence of true PDC within a geographical and histopathologically completely monitored area was 5.4 per 1,000,000. Less than 40% of the patients could be resected and they had a median survival of 23 month and an estimated 5-year survival of 27%. The prognosis of true PDC seemed lower than expected according to previously published data.

Abstract
Genome-wide association studies have identified a link between genetic variation at the human chromosomal locus 1p13.3 and coronary artery disease. The gene encoding sortilin (SORT1) has been implicated as the causative gene within the locus, as sortilin regulates hepatic lipoprotein metabolism. Here we demonstrated that sortilin also directly affects atherogenesis, independent of its regulatory role in lipoprotein metabolism. In a mouse model of atherosclerosis, deletion of Sort1 did not alter plasma cholesterol levels, but reduced the development of both early and late atherosclerotic lesions. We determined that sortilin is a high-affinity receptor for the proinflammatory cytokines IL-6 and IFN-γ. Moreover, macrophages and Th1 cells (both of which mediate atherosclerotic plaque formation) lacking sortilin had reduced secretion of IL-6 and IFN-γ, but not of other measured cytokines. Transfer of sortilin-deficient BM into irradiated atherosclerotic mice reduced atherosclerosis and systemic markers of inflammation. Together, these data demonstrate that sortilin influences cytokine secretion and that targeting sortilin in immune cells attenuates inflammation and reduces atherosclerosis.

Abstract
OBJECTIVE To determine the detection rate (sensitivity) of the high-risk strategy recommended in the European Society of Cardiology (ESC) and National Institute for Health and Care Excellence (NICE/UK) and American College of Cardiology/American Heart Association (ACC/AHA) guidelines on cardiovascular disease (CVD) prevention. In particular, to evaluate the ability to ensure statin therapy to contemporary Europeans destined for a first myocardial infarction (MI). DESIGN 393 consecutive statin-naïve, CVD-free patients without diabetes hospitalised for a first MI, 247 of whom were 40-75 years of age. We assumed they had undergone a health check the day before their MI and estimated the predicted risk. PRIMARY OUTCOME Sensitivity of the risk-based eligibility for primary prevention with statins recommended by the guidelines. RESULTS All recommended risk scores rank-ordered patients similarly, but the sensitivity of the cut point above which statin therapy should be considered differed substantially. In younger patients (age 40-60), 62% of men and 13% of women qualified for statin therapy by ACC/AHA criteria, compared with only 2% of men and no women using the ESC criteria recommended for most non-Eastern European countries. In those 60-75 years of age, the ACC/AHA guidelines captured all men and 85% of women, compared with 12% and 2%, respectively, using the new ESC guideline. This guideline restricted the eligibility for primary prevention with statins substantially by reclassifying many European countries from 'high-risk' to 'low-risk', whereas the eligibility was expanded in the ACC/AHA and the new NICE/UK guidelines by lowering the decision threshold. CONCLUSIONS The 2012 ESC guidelines differ substantially from the 2013 ACC/AHA and 2014 NICE/UK guidelines in ability to secure statin therapy to those destined for a first MI. A great opportunity for primary prevention with statins remains unexploited in Europe.

Abstract
Targeting sortilin in immune cells reduces atherosclerosis.
Background:
SNPs at 1p13.3 have been strongly associated with myocardial infarction and plasma cholesterol levels in genome-wide association studies. This locus covers 3 genes; SORT1, CELSR2 and PSRC1. Previous studies on sortilin in cardiovascular disease have focused on sortilins role in hepatic lipoprotein metabolism. In the present study, we demonstrate that sortilin also modulates atherogenesis independent of its effect on lipoprotein metabolism.
Methods and results:
The effect of sortilin deficiency on atherosclerosis was studied in
Apoe
-/-
mice. Absence of sortilin (
Sort1
-/-
) did not influence plasma cholesterol levels or the distribution between lipoprotein fractions, yet significantly reduced development of atherosclerosis after both 6 and 18 weeks of Western diet. To examine the possible mechanism we performed studies on murine bone marrow-derived macrophages (BMM) and th1-cells. Loss of sortilin did not impact foam-cell formation or cell activation, but specifically reduced the secretion of interleukin-6 (Il-6) and interferon-gamma (IFN-) from macrophages and th1 cells, respectively. Further, surface plasmon resonance analysis demonstrated that sortilin binds these two cytokines with high affinity. These results suggest that sortilin is involved in regulation of Il-6 and IFN- secretion and indicates that sortilin in immune cells may influence atherosclerosis.
To test this hypothesis, 8 weeks old
Apoe
-/-
were lethally irradiated and rescued with age- and sex-matched bone marrow from
Sort1
+/+
Apoe
-/-
or
Sort1
-/-
Apoe
-/-
donor mice. Mice with a sortilin deficient bone marrow transplant had reduced development atherosclerosis compared to mice with a
Sort1
+/+
transplant. Although these mice had normal numbers of circulating immune cells, they had reduced levels of circulating tumor necrosis factor-α and Il-6 in plasma, suggesting that absence of sortilin attenuates the inflammatory response.
Conclusions:
We conclude that targeting sortilin in immune cells reduces atherosclerosis by attenuation of the inflammatory response.

Abstract
Thirty surf lifeguards (mean (SD) age: 25.1 (4.8) years; 21 male, 9 female) were randomly assigned to perform 2 × 3 min of cardiopulmonary resuscitation on a manikin using mouth-to-face-shield ventilation (AMBU LifeKey) and mouth-to-pocket-mask ventilation (Laerdal Pocket Mask). Interruptions in chest compressions, effective ventilation (visible chest rise) ratio, tidal volume and inspiratory time were recorded. Interruptions in chest compressions per cycle were increased with mouth-to-face-shield ventilation (mean (SD) 8.6 (1.7) s) compared with mouth-to-pocket-mask ventilation (6.9 (1.2) s, p < 0.0001). The proportion of effective ventilations was less using mouth-to-face-shield ventilation (199/242 (82%)) compared with mouth-to-pocket-mask ventilation (239/240 (100%), p = 0.0002). Tidal volume was lower using mouth-to-face-shield ventilation (mean (SD) 0.36 (0.20) l) compared with mouth-to-pocket-mask ventilation (0.45 (0.20) l, p = 0.006). No differences in inspiratory times were observed between mouth-to-face-shield ventilation and mouth-to-pocket-mask ventilation. In conclusion, mouth-to-face-shield ventilation increases interruptions in chest compressions, reduces the proportion of effective ventilations and decreases delivered tidal volumes compared with mouth-to-pocket-mask ventilation.

Abstract
Forty surf lifeguards attempted to ventilate a manikin through one out of three supraglottic airways inserted in random order: the Portex® Soft Seal®; the Intersurgical® i-gel™; and the Ambu® AuraOnce™. We recorded the time to ventilate and the proportion of inflations that were successful, without and then with concurrent chest compressions. The mean (SD) time to ventilate with the Soft Seal, i-gel and AuraOnce was 35.2 (7.2)s, 15.6 (3.3)s and 35.1 (8.5) s, respectively, p < 0.0001. Concurrent chest compression prolonged the time to ventilate by 5.0 (1.3-8.1)%, p = 0.0072. The rate of successful ventilations through the Soft Seal (100%) was more than through the AuraOnce (92%), p < 0.0001, neither of which was different from the i-gel (97%). The mean (SD) tidal volumes through the Soft Seal, i-gel and AuraOnce were 0.65 (0.14) l, 0.50 (0.16) l and 0.39 (0.19) l, respectively. Most lifeguards (85%) preferred the i-gel. Ventilation through supraglottic airway devices may be considered for resuscitation by surf lifeguards.

Abstract
Lack of animal models with human-like size and pathology hampers translational research in atherosclerosis. Mouse models are missing central features of human atherosclerosis and are too small for intravascular procedures and imaging. Modeling the disease in minipigs may overcome these limitations, but it has proven difficult to induce rapid atherosclerosis in normal pigs by high-fat feeding alone, and genetically modified models similar to those created in mice are not available. D374Y gain-of-function mutations in the proprotein convertase subtilisin/kexin type 9 (PCSK9) gene cause severe autosomal dominant hypercholesterolemia and accelerates atherosclerosis in humans. Using Sleeping Beauty DNA transposition and cloning by somatic cell nuclear transfer, we created Yucatan minipigs with liver-specific expression of human D374Y-PCSK9. D374Y-PCSK9 transgenic pigs displayed reduced hepatic low-density lipoprotein (LDL) receptor levels, impaired LDL clearance, severe hypercholesterolemia, and spontaneous development of progressive atherosclerotic lesions that could be visualized by noninvasive imaging. This model should prove useful for several types of translational research in atherosclerosis.

Abstract
INTRODUCTION Atherosclerotic cardiovascular disease (CVD), including acute myocardial infarction (AMI), is caused by well-known risk factors. They constitute important therapeutic targets, but their predictive value is disputed. We evaluated the effectiveness of the risk scoring system (SCORE) and thresholds for pharmacotherapy re-commended in the European guidelines on CVD prevention. MATERIAL AND METHODS The medical records of 605 consecutive patients hospitalized for a first AMI were reviewed. Patients with pre-existing CVD, diabetes, or incomplete information on risk factors were excluded. Those not treated with statin before AMI were risk stratified based on risk factors. A SCORE ≥ 5% or ≥ 10% was considered to qualify for preventive medication in young adults (age ≤ 60 years) or elderly (age > 60 years), respectively. RESULTS Before AMI, 40 (9%) used statin. Among non-statin users, only five of the 109 young adults had a SCORE ≥ 5%, and 23 of the 284 elderly had a SCORE ≥ 10%. Among women, only three elderly qualified for treatment. More than four times more patients would have qualified for treatment with the high-risk country chart used in 2011. The incremental value of the novel high-density lipoprotein adjusted SCORE charts was limited. CONCLUSION Few patients admitted with a first AMI used statin. Among non-statin users, SCORE and the recommended thresholds for pharmacotherapy identified no women and less than one out of ten men who untreated were destined for an AMI before 61 years of age. The preventive potential of a traditional risk factor-based health check is limited. FUNDING not relevant. TRIAL REGISTRATION not relevant.

Characteristics, therapy and outcome in an unselected and prospectively registered cohort of pancreatic cancer patients. Eur J Cancer 2012; 49:98-105. [PMID: 22909997 DOI: 10.1016/j.ejca.2012.07.017] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2012] [Revised: 06/14/2012] [Accepted: 07/08/2012] [Indexed: 12/23/2022]
Abstract
PURPOSE Pancreatic cancer (PC) is associated with a dismal prognosis. Few studies have examined characteristics and outcome in an unselected population-based cohort of PC patients. Therefore, we investigated patient baseline characteristics, therapy choices and survival in a complete cohort of patients with PC. METHODS All cases diagnosed with PC between 2007 and 2009 in the Region of Southern Denmark (pop: 1,200,000) were prospectively registered. Patient characteristics including performance status, information about haematology, liver function and therapy were retrieved from patient charts, and used to compare differently treated and untreated groups. RESULTS Six-hundred-eighteen cases were registered as PC; 25 of which did not have adenocarcinomas. Patients were divided in 3 clinical groups based on initial therapy; group 1: resection (n=64), group 2: chemotherapy or chemo-radiotherapy (n=191), group 3: no tumour directed therapy (n=324). Median survival (mOS) (95% confidence interval (CI)) in the three groups was 25.7 months (18-30), 8.1 months (7.0-9.5) and 1.1 months (1.0-1.3) respectively. Three percent of patients participated in clinical trials. An evaluation of baseline factors prognostic value suggested that treated patients differed significantly from non-treated patients. CONCLUSION This study reports survival in treated groups comparable to results obtained from clinical trials with highly selected patients. However the majority of patients with PC do not receive cancer directed therapy. This group was significantly different in several baseline factors, which could suggest a different biology. Improving the outcome of PC patients calls for research into the large group of untreated patients, as only a minority of patients receive cancer directed therapy.

Abstract
BACKGROUND AND STUDY AIMS Accurate lymph node staging is essential for the selection of an optimal treatment in patients with upper gastrointestinal cancer. Endoscopic ultrasound (EUS) and fine-needle aspiration (FNA) are considered to be the most accurate method for locoregional staging. Endoscopic sonoelastography (ESE) assesses the elasticity of lymph nodes and has been used to differentiate lymph nodes with promising results. The aim of this study was to evaluate the use of EUS, EUS - FNA, ESE, and ESE-strain ratio using histology as the gold standard. PATIENTS AND METHODS Patients with upper gastrointestinal cancer who were referred for EUS examination were enrolled if surgical treatment was planned and the patient had a lymph node that was accessible for EUS - FNA and EUS-guided fine-needle marking (FNM). The lymph node was classified using EUS, ESE, and ESE-strain ratio. Finally, EUS - FNA and EUS - FNM were performed. The marked lymph node was isolated during surgery for histological examination. RESULTS The marked lymph node was isolated for separate histological examination in 56 patients, of whom 22 (39 %) had malignant lymph nodes and 34 (61 %) had benign lymph nodes. There were no complications of EUS - FNM. The sensitivity of EUS for differentiation between malignant and benign lymph nodes was 86 % compared with 55 % - 59 % for the different ESE modalities. The specificity of EUS was 71 % compared with 82 % - 85 % using ESE modalities. CONCLUSION The use of the EUS - FNM technique enabled the identification of a specific lymph node and thereby the use of histology as gold standard. ESE and ESE-strain ratio were no better than standard EUS in differentiating between malignant and benign lymph nodes in patients with resectable upper gastrointestinal cancer.

Abstract
PURPOSE There is a lack of studies on the intra- and interobserver variability of endoscopic ultrasonography (EUS) and especially endoscopic sonoelastography (ES). The aim of this study was to evaluate the intra- and interobserver agreement of EUS and ES during the evaluation of a specific lymph node in patients with upper gastrointestinal malignancies (UGIM). The ES strain ratio was used to differentiate between benign and malignant lymph nodes and the interobserver agreement was evaluated. MATERIALS AND METHODS This study prospectively enrolled 62 patients with UGIM. EUS and ES were performed by two observers in randomized order of a specific lymph node using a linear Pentax echoendoscope and the Hitachi EUB-8500 US unit. The lymph node was classified as malignant or benign on the basis of EUS, ES, an ES scoring system, and 5 repeated strain ratio measurements. The intraobserver variation was evaluated by each observer performing 20 strain ratio measurements of the same lymph node. Finally, EUS fine needle aspiration was performed. The kappa statistic was used to test for interobserver variability. RESULTS One patient was excluded due to inadequate ES imaging. Thus, 61 patients were included in the analysis of the interobserver agreement. Using EUS, ES, and an ES scoring system, the kappa values were 0.80, 0.58, and 0.35, respectively. An ES strain ratio of 3.81 was defined as the cut-off value between benign and malignant lymph nodes using cytology as the gold standard (n = 55). Using this modality, a kappa value of 0.59 was obtained. A t-test comparison of the measured strain ratios for the two observers found no significant differences. CONCLUSION ES and ES strain ratio evaluation of lymph nodes were feasible and may be reproduced with good interobserver agreement in a blinded clinical setup. The predefined ES scoring system provided only poor interobserver agreement. Image selection should be part of the intra- and interobserver evaluation. ES strain ratio seemed promising but larger studies are needed to evaluate this new feature.

Abstract
AIMS Endothelial regeneration after vascular injury, including percutaneous coronary intervention, is essential for vascular homeostasis and inhibition of neointima formation. Circulating endothelial progenitor cells (EPCs) have been implicated to contribute by homing and differentiating into endothelial cells (ECs). We tested this theory in a murine arterial injury model using carotid artery transplants and fluorescent reporter mice. METHODS AND RESULTS Wire-injured carotid artery segments from wild-type mice were transplanted into TIE2-GFP transgenic mice expressing green fluorescent protein (GFP) in ECs. We found that the endothelium regenerated with GFP(+) ECs as a function of time, evolving from the anastomosis sites towards the centre of the transplant. A migration front of ECs at Day 7 was verified by scanning electron microscopy and by bright-field microscopy using recipient TIE2-lacZ mice with endothelial β-galactosidase expression. These experiments indicated migration of flanking ECs rather than homing of circulating cells as the underlying mechanism. To confirm this, we interposed non-injured wild-type carotid artery segments between the denuded transplant and the TIE2-GFP recipient mouse. Among 1186 ECs identified in re-endothelialized transplants (n= 5) by staining for von Willebrand Factor or vascular endothelial-cadherin, we did not find any blood-derived (GFP(+)) cells. CONCLUSION Endothelial regeneration after vascular injury did not involve circulating EPCs but was mediated solely by migration of ECs from the adjacent healthy endothelium.

Abstract
BACKGROUND AND STUDY AIMS No previous studies have evaluated the ability of endoscopic ultrasonography to describe the anatomic location of lymph nodes on the basis of a node-to-node comparison. The aim of this study was to assess the feasibility and safety of a new endoscopic ultrasound (EUS)-guided fine-needle technique for marking lymph nodes. PATIENTS AND METHODS Twenty-five patients with suspected or confirmed malignancies of the upper gastrointestinal tract were prospectively included. EUS-guided fine-needle marking (EUS-FNM) was performed with a silver pin with a diameter that allowed it to fit into a 19-gauge needle. The position of the pin was verified by EUS. End points were the ability to identify and isolate the marked lymph node during surgery and a comparison between the location of the pin as suggested by EUS and the actual location found in the resected specimen. RESULTS Twenty-three lymph nodes were marked. Nineteen intended surgical isolations were performed. The lymph nodes were isolated in the resection specimens in 18 patients (95 %). In 2 out of 20 cases the pin was not localized by laparoscopic ultrasonography. In 89 % of the cases the marked lymph node was in the same location as described by EUS. One pin (5 %) was not retrieved. In three cases, a small hematoma was observed. There was no sign of long-term complications. CONCLUSION EUS-FNM with a silver pin in lymph nodes is feasible and safe. EUS-FNM seems to be a suitable tool for evaluating lymph nodes on the basis of a node-to-node comparison.
