Objective: The characteristics and outcomes of patients undergoing vascular surgery hospitalised and managed in Lombardy are described with a comparison of patients tested positive for COVID-19 (CV19-pos) vs. those tested negative (CV19-neg). Methods: This was a multicentre, retrospective, observational cohort study which involved all vascular surgery services in Lombardy, Northern Italy. Data were retrospectively merged into a combined dataset covering the nine weeks of the Italian COVID-19 pandemic phase 1 (8 March 2020 to 3 May 2020). The primary outcome was freedom from in hospital death, secondary outcomes were re-thrombosis rate after peripheral revascularisation, and freedom from post-operative complication. Results: Among 674 patients managed during the outbreak, 659 (97.8%) were included in the final analysis: 121 (18.4%) were CV19-pos. CV19-pos status was associated with a higher rate of complications (OR 4.5; p < .001, 95% CI 2.64 – 7.84), and a higher rate of re-thrombosis after peripheral arterial revascularisation (OR 2.2; p = .004, 95% CI 1.29 – 3.88). In hospital mortality was higher in CV19-pos patients (24.8% vs. 5.6%; OR 5.4, p < .001;95% CI 2.86 – 8.92). Binary logistic regression analysis identified CV19-pos status (OR 7.6; p < .001, 95% CI 3.75 – 15.28) and age > 80 years (OR 3.2; p = .001, 95% CI 1.61 – 6.57) to be predictors of in hospital death. Conclusion: In this experience of the vascular surgery group of Lombardy, COVID-19 infection was a marker of poor outcomes in terms of mortality and post-operative complications for patients undergoing vascular surgery treatments.

Graphical abstract, Highlights • The origins and courses of the coronary arteries can be detected on TTE. • Three “echo-signs” can detect an anomalous origin of the circumflex coronary artery. • A significant stenosis in the anomalous left circumflex artery can be detected on TTE.

BACKGROUND: To highlight clinical practice among referral (Hub, HH) or satellite (Spoke, SH) hospitals Vascular Surgery Units (VSUs) in Lombardy, during the COVID-19 pandemic "phase 1" period (March 8 - May 3, 2020). METHODS: The Vascular Surgery Group of Regione Lombardia Register, a real-word, multicenter, retrospective register was interrogated. All patients admitted with vascular disease were included. Patients' data on demographics, COVID-19 positivity, comorbidities and outcomes were extrapolated. Two cohorts were obtained: patients admitted to HH or SH. Primary endpoint was 30- day mortality rate. Secondary outcomes were 30-day complications and amputation (in case of peripheral artery disease [PAD]) rates. Univariate and multivariate analysis were used to compare HH and SH groups and predictors of poor outcomes. RESULTS: During the study period, 659 vascular patients in 4 HH and 27 SH were analyzed. Among these, 321 (48.7%) were admitted to a HH. No difference in COVID-19 positive patients was described (21.7% in HH vs 15.9% in SH; p=.058). After 30 days from intervention, HH and SH experienced similar mortality and no-intervention-related complication rate (12.1% vs 10.0%; p=.427 and 10.3% vs 8.3%; p=.377, respectively). Conversely, in HH postoperative complications were higher (23.4% vs 16.9%, p=.038) and amputations in patients treated for PAD were lower (10.8% vs 26.8%; p

The possibility of coming to a “good death” is a challenging issue that crosses ethical and religious beliefs, cultural assumptions, as well as medical expertise. The provision of palliative care for relieving patients’ pain is a practice that reshapes the path to the event of death and gives form to a particular context of awareness, recalling the notion proposed by Glaser and Strauss. This decision redesigns the relationships between patients, practitioners and caregivers and introduces a new pattern of collaboration between them. Our study focuses on the implications of the collaboration between practitioners and caregivers, starting from the assumption that the latter may provide support to their loved ones and to the practitioners, but need to be supported too. We provide a qualitative analysis of this collaboration based on an empirical research that took place in four different settings of provision of palliative care, reporting the contrast between the affective engagement of caregivers and the professional approach of practitioners. We claim that this ambivalent collaboration, while embedded in contingent and incommensurable experiences, brings to the fore the broader understanding of the path to a “good death,” outlining its societal representation as a collective challenge.

To evaluate the incidence of in-stent restenosis (ISR) at 12-month follow-up, in patients treated with new dual-layer Roadsaver (Terumo Corp, Tokyo, Japan) carotid artery stent (CAS). Thirteen patients underwent CAS and received a Roadsaver. Neurological examination was performed in all patients. Carotid stenosis was revealed by Doppler ultrasound (DUS) and multidetector CT (MDCT) scan. Four patients presented a peak systolic velocity (PSV) between 130 and 150 cm/s, six a PSV between 150 and 180 cm/s, and three a PSV > 180 cm/s. MDCT gave further anatomic information. Direct stenting was performed in 11 (84.6%) cases, whereas in 2 (15.4%) cases predilatation was required. In all cases postdilatation was performed. Technical and clinical success and safety were evaluated. Stent patency was evaluated during the 12-month follow-up. Technical success was achieved in all cases. In three patients a nonsignificant residual stenosis

Warfarin-related nephropathy is an unexplained acute kidney injury, and may occur in patients with supratherapeutic INR, in the absence of overt bleeding. Similar findings have been observed in rats treated with dabigatran etexilate. We conducted a prospective study in dabigatran etexilate-treated patients to assess the incidence of dabigatran-related nephropathy and to investigate the possible correlation between dabigatran plasma concentration (DPC) and worsening renal function. One hundred and seven patients treated long term with dabigatran etexilate for non-valvular atrial fibrillation (NVAF) were followed up for 90 days. DPC, serum creatinine (SCr) and serum cystatin C were prospectively measured. Ninety five patients had complete follow-up data and were evaluable for primary endpoint. Eleven patients had supratherapeutic DPC, defined as DPC higher than 200 ng/ml at study enrolment, but at the end of follow-up no patient showed a persistent increase in SCr. No patients experienced acute kidney injury. Our study shows that no persistent renal detrimental effect is associated with dabigatran treatment. An increase in SCr during dabigatran treatment is reversible and it seems to be unrelated to dabigatran itself.

Introduction In the treatment of patients with atrial fibrillation (AF) who undergo percutaneous coronary intervention (PCI), it is unclear which combination of antithrombotic drugs is preferable and which is the optimal duration of treatment. Areas covered The authors review the available evidence in this area resulting from single studies and meta-analyses. In the absence of direct head-to-head comparisons between different non-vitamin K oral anticoagulants (NOAC), the authors review the available studies with NOACS in these patients and derived indirect comparisons. Expert opinion In patients with AF who undergo PCI, a dual antithrombotic strategy which includes a NOAC plus single antiplatelet therapy with a P2Y12 inhibitor (preferably clopidogrel) should be considered as the preferred treatment option in most cases. Oral anticoagulation associated with dual antiplatelet therapy (triple antithrombotic therapy) should be offered for no longer than 30 days to patients with very high thrombotic and low hemorrhagic risk. It is unclear whether the dual antithrombotic strategy should be continued beyond 12 months in patients at high risk of thrombotic events. Additional data from adequately powered controlled studies are needed to support the long-term efficacy of this strategy and to establish the best patient-tailored approach in this complex scenario.

Background: Cancer patients experience multiple symptoms throughout the course of the disease. We aimed to provide a comprehensive analysis of the symptom burden in patients with advanced cancer at admission to specialist palliative care (PC) services and seven days later to estimate the immediate impact of PC intervention. Patient and methods: The analysis was based on an observational, prospective, multicenter study (named DEMETRA) conducted in Italy on new patients accessing network specialist PC centers during the period May 2017&ndash, November 2017. The prevalence and intensity of symptoms were assessed at baseline and after seven days using three tools including the Edmonton Symptom Assessment System (ESAS). Results: Five PC centers recruited 865 cancer patients. Thirty-three different symptoms were observed at the baseline, the most frequent being asthenia (84.9%) and poor well-being (71%). The intensity of the most frequent symptoms according to ESAS ranged from 5.5 for asthenia to 3.9 for nausea. The presence and intensity of physical symptoms increased with increasing levels of anxiety and depression. After seven days, prevalence of nausea and breathlessness as well as intensity of almost all symptoms significantly decreased. Conclusions: The study confirmed the considerable symptom burden of patients with advanced cancer. PC intervention has significantly reduced the severity of symptoms, despite the patients&rsquo, advanced disease and short survival.

Background: Cancer patients experience a number of symptoms throughout the course of the disease. We aimed to provide a comprehensive analysis of the symptom burden in patients with advanced cancer at admission to specialist palliative care (PC) services and seven days later, to estimate the immediate impact of PC intervention.Patient and methods: The analysis was based on an observational, prospective, multicenter study (named DEMETRA) conducted in Italy to outline the profile of patients, families and PC services in different care settings (hospital, hospice and home care). The prevalence and intensity of symptoms were assessed using three tools, including the Edmonton Symptom Assessment System (ESAS).Results: Five PC centers recruited 865 cancer patients. Thirty-three different symptoms were observed at baseline, the most frequent being asthenia (85%) and lack of appetite (71%). Two-thirds of patients experienced six to twelve simultaneous symptoms. The intensity of the most frequent symptoms according to ESAS varied from 5.5 for asthenia to 3.9 for nausea. The presence and intensity of physical symptoms increased with increasing levels of anxiety and depression. After seven days, prevalence decreased significantly only for nausea and breathlessness, while intensity diminished significantly for almost all symptoms. At admission we noted a correlation between patients' symptoms and the care setting. After one week, the symptom intensity was uniformly reduced in all settings.Conclusions: The study confirmed the considerable symptom burden of patients with advanced cancer. PC intervention significantly lessened the severity of symptoms, despite the patients’ advanced disease and short survival.

ObjectivesThe aim of this work is to describe the multidisciplinary model of intervention applied and the characteristics of some COVID-19 patients assisted by the hospital palliative care unit (UCP-H) of an Italian hospital in Lombardy, the Italian region most affected by the COVID-19 pandemic.MethodsA retrospective study was conducted on patients admitted to the A. Manzoni Hospital (Lecco, Lombardy Region, Italy) and referred to the UCP-H between 11 March 2020 and 18 April 2020, the period of maximum spread of COVID-19 in this area. Data were collected on the type of hospitalisation, triage process, modality of palliative care and psychological support provided.Results146 COVID-10 patients were referred to the UCP-H. Of these, 120 died during the observation time (82%) while 15 (10.2%) improved and were discharged from the UCP-H care. 93 had less favourable characteristics (rapid deterioration of respiratory function, old age, multiple comorbidities) and an intensive clinical approach was considered contraindicated, while 48 patients had more favourable presentations. Mean follow-up was 4.8 days. A mean of 4.3 assessments per patient were performed. As to respiratory support, 94 patients were treated with oxygen only (at different volumes) and 45 with Continuous Positive Airway Pressure (CPAP).ConclusionThe ongoing pandemic highlighted the need for dedicated palliative care teams and units for dying patients. This work highlights how palliative medicine specialist can make a fundamental contribution thanks to their ability and work experience in an organised multiprofessional context.

Background: Dependency in older ages is increasing. Many older persons receive care while living in the community. We aimed to identify the predictive value of four clinical measurements to predict home care intensity in older patients following discharge from hospital to home care over 90days. Methods: We included 425 inpatients from the “Frailty Department–Local Palliative Care Network” of the local social health authority (ASST) Lecco, Italy (mean age 75.4years, SD 14.5; female 75.5%). Changes in Health, End-stage disease, and Signs and Symptoms, light version (CHESS-Lite), activities of daily living (ADL), frailty, and the Service Urgency Algorithm. Receiver operative curves were used to calculate thearea under the curve (AUC) for predicting Home Care Intensity coefficient (ratio of the number of days when any home care was provided 90days post-discharge). The interRAI Contact Assessment Instrument was used to calculate these measures. Results: Analysis was stratified using six different home care intensity score cut-offs. CHESS-Lite had a higher AUC for predicting home care intensity at all cut-off levels but was best for predicting the highest level of home care intensity (≥ 0.8) where the AUC was 0.71 (0.64–0.79). The frailty index also had an acceptable AUC. ADL had the lowest AUC. Conclusions: Health instability measured with CHESS-Lite has a high predictive value for identifying home care intensity in geriatric patients after discharge from hospital to home, especially in persons with higher home care intensity scores. Geriatric patients with high health instability should be focused on at discharge to prioritize assessment and initiate timely services for home care support.

Background: The aim of this study was to investigate the effect of the time interval from clinical presentation of arteriovenous graft thrombosis and the thrombectomy procedure by the AngioJet system in terms of technical and clinical success and to identify factors influencing success. Methods: A total of 60 consecutive patients (35 men and 25 women; mean age = 52 ± 7.89 years) who had undergone percutaneous thrombectomy by the AngioJet device from 2016 to 2019 were retrospectively enrolled. Demographics and fistula data, previous treatments, time from clinical onset of thrombosis to intervention, procedural details and complications were recorded. Technical and clinical success and primary and secondary patency rates were calculated. One-way analysis of variance was performed to test any correlation between patient-related and fistula/procedure-related variables and technical/clinical success. Odds ratio and relative risk were also calculated when necessary. Results: Technical success and clinical success were 95% and 91.7%, respectively. Post-interventional primary and secondary patency rates at 1 year were 72.5% and 84.3%, respectively. Complication rate was 6.7%. One-way analysis of variance showed that clinical success was higher in patients with no previous treatment (p = 0.015). Furthermore, clinical success was significantly associated with door to angiographic bed time (p = 0.002): p-value for the 24-h and the 72-h cut-off was 0.012 and 0.006, respectively. Conclusion: Percutaneous rheolytic thrombectomy is safe and effective for thrombosed arteriovenous grafts, with acceptable primary and secondary patency rates. Higher clinical success was found in patients never treated before and when the procedure was carried out within 24 h from the clinical onset of thrombosis.

Background: The sustainability of palliative care services is nowadays crucial inasmuch as resources for palliative care are internationally scarce, the funding environment is competitive, and the potential population is growing. Methods: The DEMETRA study is a multicentre prospective observational study, describing the intensity of care and the related costs of palliative home care pathways. Results: 475 patients were enrolled as recipients of specialized palliative home care. The majority of recipients were cancer patients (89.4%). The mean duration of palliative care pathways was 46.6 days and mean home care intensity coefficient equal to 0.6. The average daily cost of the model with the reference variables is 96.26 euros. Factors statistically significantly associated with an increase in mean daily costs were greater dependence and extreme frailty (p < 0.05). Otherwise, a longer duration of treatment course was associated with a significant decrease in mean daily costs (p < 0.001). Conclusions: In terms of clinical and organizational management, considering the close association with the intensity and cost of the path, frailty should be systematically assessed by all facilities that potentially refer patients to home palliative care teams, and it should be carefully recorded in a standardized payment rate perspective.

Objectives The purpose of this study was to evaluate the safety and efficacy of uninterrupted and interrupted direct oral anticoagulant (DOAC) administration in patients undergoing pulmonary vein isolation (PVI). Background The optimal periprocedural management of DOACs in patients undergoing PVI is not well defined, and different strategies are used. Methods A systematic search of PubMed/MEDLINE, Ovid/MEDLINE, and EMBASE was performed. Three strategies for periprocedural DOAC administration were considered: uninterrupted, mildly interrupted ( Results The analysis included 43 studies for a total of 8,362 patients. DOACs showed similar safety and efficacy in the 3 subgroups. The WMI of MB was 1.02%, 1.49%, and 1.17% for the uninterrupted, mildly interrupted, and interrupted strategy, respectively; the WMI of TE complications was 0.16%, 0.46%, and 0.49% for the uninterrupted, mildly interrupted, and interrupted strategy, respectively, with no heterogeneity. OB appeared to be higher in uninterrupted (6.33%) and mildly interrupted (8.62%) groups compared with the interrupted (3.53%), with substantial heterogeneity among studies. No interaction was found between the incidence of MB and TE complications and different DOACs. Conclusions In patients undergoing PVI, these 3 anticoagulation strategies may have similar safety and efficacy in terms of MB and TE complications. OB appears to be higher in uninterrupted and mildly interrupted strategies compared with the interrupted strategy. No substantial differences were observed among DOACs regarding the incidence of MB and TE complications.

Endovascular aneurysm repair (EVAR) is associated with decreased periprocedural mortality, complications, and length of hospital stay compared to open repair.

Several arrhythmogenic substrates may generate narrow QRS complex tachycardia, frequently encountered in clinical practice. Some narrow QRS complex tachycardias, however, are sustained by an uncommon arrhythmogenic mechanism. Although rare, these forms should be taken into account in the differential diagnosis to avoid misdiagnosis and improper patient management. Dual atrioventricular node physiology can be responsible for different uncommon forms of narrow QRS complex tachycardia, also nonreentrant in mechanism. A ventricular origin also is possible, if the tachycardia site is located in the upper ventricular septum with fast ventricular propagation to the specific conduction system and narrowing of the QRS complex.

Background: In Italy, there currently is a lack of reliable and consistent data on home palliative care provided to people near death. Objectives: Monitoring the activities of the Italian Home Palliative Care Services, according to the 2014 national data collection program entitled &ldquo, Observatory of Best Practices in Palliative Care&rdquo, and providing process/outcome measures on a subsample (Best Practice Panel), on regulatory standards and on complete/reliable activity data. Design: A data collection web portal using two voluntary internet-based questionnaires in order to retrospectively identify the main care activity data provided within the year 2013 by Home care units. In the Best Practice Panel and International best practices, eligibility and quality measures refer to the national standards of the NL 38/2010. Setting/Subject: Home Palliative Care Services (HPCSs) that provided care from January to December 2013. Results: 118 Home care units were monitored, globally accounting for 40,955 assisted patients within the year 2013 (38,384 cancer patients), 56 (47.5% of 118) were admitted in the Best Practice Panel. Non-cancer (5%) and pediatric (0.4%) patients represented negligible percentages of frail care patients, and a majority of patients died at home (respectively nearly 75% and 80% of cancer and non-cancer patients). Conclusion: The study demonstrated the feasibility of the collection of certified data from Home care services through a web-based system. Only 80% of the facilities met the requirements provided by the Italian NL 38/2010. Moreover, the extension of the palliative care services provided to frail non-cancer and pediatric patients, affected by complex and advanced chronic conditions, is still inadequate in Italy.

In order to plan the right palliative care for patients and their families, it is essential to have detailed information about patients&rsquo, needs. To gain insight into these needs, we analyzed five Italian local palliative care networks and assessed the clinical care conditions of patients facing the complexities of advanced and chronic disease. A longitudinal, observational, noninterventional study was carried out in five Italian regions from May 2017 to November 2018. Patients who accessed the palliative care networks were monitored for 12 months. Sociodemographic, clinical, and symptom information was collected with several tools, including the Necesidades Paliativas CCOMS-ICO (NECPAL) tool, the Edmonton Symptom Assessment System (ESAS), and interRAI Palliative Care (interRAI-PC). There were 1013 patients in the study. The majority (51.7%) were recruited at home palliative care units. Cancer was the most frequent diagnosis (85.4%), and most patients had at least one comorbidity (58.8%). Cancer patients reported emotional stress with severe symptoms (38.7% vs. 24.3% in noncancer patients, p = 0.001) and were less likely to have clinical frailty (13.3% vs. 43.9%, p &lt, 0.001). Our study confirms that many patients face the last few months of life with comorbidities or extreme frailty. This study contributes to increasing the general knowledge on palliative care needs in a high-income country.

Symptomatic obstruction related to malignant involvement of large veins may occur in central veins both in the thoracic and pelvic regions, and in the abdominal region of the body. Both cases represent a therapeutic challenge, and endovascular revascularization, consisting of angioplasty and stent placement, is safe and effective. Superior vena cava stenting has become widespread in the management of occlusive venous disease. The percutaneous placement of large expandable metal stents allows rapid restoration of normal blood flow in the majority of patients, thus improving symptoms. Published data on the diagnosis and treatment of symptomatic cancer-related iliocaval obstructions are limited and mainly consist of case reports and small case series. The present review reports the current state of endovascular treatment for both superior vena cava occlusion and iliac compression syndrome in cancer patients.

The purpose of this study was to evaluate the safety and efficacy of uninterrupted and interrupted direct oral anticoagulant (DOAC) administration in patients undergoing pulmonary vein isolation (PVI).The optimal periprocedural management of DOACs in patients undergoing PVI is not well defined, and different strategies are used.A systematic search of PubMed/MEDLINE, Ovid/MEDLINE, and EMBASE was performed. Three strategies for periprocedural DOAC administration were considered: uninterrupted, mildly interrupted (12 h), and interrupted (≥12 h). Primary endpoints were major bleeding (MB) and thromboembolic (TE) complications; pooled weighted mean incidence (WMI) was calculated using a random-effects model. A secondary endpoint was the WMI of overall bleeding (OB).The analysis included 43 studies for a total of 8,362 patients. DOACs showed similar safety and efficacy in the 3 subgroups. The WMI of MB was 1.02%, 1.49%, and 1.17% for the uninterrupted, mildly interrupted, and interrupted strategy, respectively; the WMI of TE complications was 0.16%, 0.46%, and 0.49% for the uninterrupted, mildly interrupted, and interrupted strategy, respectively, with no heterogeneity. OB appeared to be higher in uninterrupted (6.33%) and mildly interrupted (8.62%) groups compared with the interrupted (3.53%), with substantial heterogeneity among studies. No interaction was found between the incidence of MB and TE complications and different DOACs.In patients undergoing PVI, these 3 anticoagulation strategies may have similar safety and efficacy in terms of MB and TE complications. OB appears to be higher in uninterrupted and mildly interrupted strategies compared with the interrupted strategy. No substantial differences were observed among DOACs regarding the incidence of MB and TE complications.

Objective: The aim of this study was to illustrate the characteristics of patients with palliative care (PC) needs, early identified by general practitioners (GPS), and to analyze their care process in home PC services. Background: Early identification and service integration are key components to providing quality palliative care (PC) services ensuring the best possible service for patients and their families. However, in Italy, PC is often provided only in the last phase of life and for oncological patients, with a fragmented service. Methods: Multicenter prospective observational study, lasting in total 18 months, implemented in a sample of Italian Home Palliative Care Units (HPCUs), enrolling and monitoring patients with limited life expectancy, early identified by 94 GPS. The study began on March 1, 2014 and ended on August 31, 2015. Results: Nine hundred thirty-seven patients, out of a total pool of 139,071, were identified by GPS as having a low life expectancy and PC needs. Of these, 556 (59.3%) were nononcological patients. The GPS sent 433 patients to the HPCUs for multidimensional assessment, and 328 (75.8%) were placed in the care of both settings (basic or specialist). For all patients included in the study, both oncological and nononcological patients, there was a high rate of death at home, around 70%. Discussion: This study highlights how a model based on early identification, multidimensional evaluation, and integration of services can promote adequate PC, also for noncancer patients, with a population-based approach.

To evaluate safety, technical and clinical success of embolization of type Ia endoleak (T1a EL) using ethylene–vinyl alcohol copolymer as embolic agent alone or in combination with other materials. Five patients presented T1a EL after endovascular repair of aortic aneurysms (EVAR) with radiological evidence of expanding sac size; in particular, three had contained rupture. In one patient, proximal cuff insertion was previously performed, in three patients proximal cuff was urgently inserted but T1a EL persisted; one patient, previously treated with Ovation Abdominal Stent Graft System, was directly proposed for endovascular treatment. In all cases, endovascular embolization was successfully performed and the transfemoral approach was always chosen; in one case it failed and translumbar approach by direct puncture of the sac was required. Used embolization agents were glue, ethylene–vinyl alcohol copolymer (Onyx) and coils in three cases, n-butyl cyanoacrylate and Onyx in one case, Onyx and coils in the last case. Technical success rate was 100% as well as clinical success. No major or minor complication, including non-target embolization, was registered. Clinical success was 100% until today and the sac diameter remained stable in four patients and decreased in one. Onyx may be considered a suitable embolic agent in the treatment of patients with type Ia endoleaks after EVAR, after failure of conventional treatments such as prolonged balloon inflation of the aortic neck or deployment of large bare stent.

Pulmonary Embolism (PE) incidence increases with age. Data on mortality and prognosis in elderly patients with suspected PE are lacking. (1) To assess 30- and 90-day mortality in subjects with PE from an elderly population seen in the emergency department (ED); (2) to test the prognostic accuracy of a simplified Pulmonary Embolism Severity Index (sPESI) coupled to a highly sensitive cardiac Troponin T (hs-cTnT) level. A retrospective cohort study was performed, including patients evaluated in the ED of Vimercate Hospital for clinically suspected PE from 2010 to 2012. Study population: n = 470, 63.4 % women, mean age ± SD 73.06 ± 16.0 years, 40 % aged ≥80 and 77.7 % ≥65 years old, confirmed PE: 22.6 % (106 cases). Within 30 and 90 days, mortality among patients with confirmed PE was 14.2 % (8.8–22.0) and 20.8 % (16.5–41.7). In subjects aged ≥80 years, 30-day mortality was 18.9 % among patients with confirmed PE, and 12.6 % among those with PE excluded (p = 0.317). Ninety-day mortality rates were 29.7 and 19.9 %, respectively (p = 0.193). In patients with confirmed PE, Negative Predictive Value of sPESI was 94.1 % (80.3–99.3) for 30 days and 88.2 % (72.3–96.7) for 90-day mortality. Adding the hs-cTnT level to sPESI did not improve its performance. (1) In an elderly population referring to the ED with clinically suspected PE, mortality was high both in subjects with and without confirmed PE; (2) the ability of sPESI and hs-cTnT to predict PE mortality seems to be lower than reported in studies based on data from younger populations. Better risk stratification tools will be necessary to improve clinical management in this setting.

Introduction D-dimer is commonly used in the workup of suspected Pulmonary Embolism (PE), but its specificity decreases with age. We evaluated whether using a higher cutoff value for D-dimer could increase the test specificity without reducing its sensitivity for ruling-out PE in elderly and very elderly patients presenting to the Emergency Department (ED). Material and Methods All patients with D-dimer and pulmonary Computed Tomography Angiography (CTA) performed in the ED of Vimercate Hospital, from 2010 through 2012 for clinical suspicion of PE were included in this retrospective cohort study. Results Study population 481 patients (63.4% women, mean age 73.0 ± 16.1 years, confirmed PE 22.5%). In very elderly patients (aged 80 or more years, n = 191), compared with standard 490 ng/mL D-dimer threshold, both higher fixed (1000 ng/mL) and age-adjusted cutoffs increase the specificity of D-dimer for the exclusion of PE maintaining a Negative Predictive Value of 100%. Potentially avoided CTAs were 12(6.3%) using 1000 ng/mL cutoff and 10(5.2%) age-adjusted. In very elderly patients the Number Needed to Test was incalculable for the standard cutoff (0 cases), 16 for 1000 ng/mL and 19 for age-adjusted. In patients with PE, index episode mortality was 6.5%, and death occurred only in subjects with D-dimer values above 1000 ng/mL and age-adjusted thresholds. Conclusion For very elderly patients with suspected PE in ED, both higher fixed D-dimer (1000 ng/mL) and age-adjusted thresholds increase test specificity for excluding PE without reducing its sensitivity, leading to a safe reduction in the number of CTAs.

The recent history of Burundi is characterized by cyclical ethnic strife between the Hutu majority, comprising approximately 85 per cent of the population, and the Tutsi. A peace agreement was signed in 2000, and in 2005 the UN recommended the establishment of a dual mechanism, namely a non-judicial accountability mechanism in the form of a truth commission, and a judicial accountability mechanism in the form of a special chamber. Little progress toward their establishment was achieved, however, with the process stalled by outbreaks of violence and the country’s fragmented political milieu. In 2011, significant momentum has been gained with the completion of a country-wide consultation process and the resumption of negotiations between the government and the UN. Building upon these developments, this article reviews the architecture of the proposed mechanism and sets forth various considerations for the creation of the Truth and Reconciliation Commission and the Special Chamber for Burundi.

Novel plate-type heat exchangers (HXs) with high-power densities are proposed based on novel integrated flow channel designs. Net-shape plates were achieved by the molding of powder mixtures to wood-based composites (WBC's). HX stacks are built by plate-to-plate joining followed by pyrolysis and silicon melt infiltration. The C/SiSiC provided with PyC–SiC coating was gas-tight to helium up to 5.5 MPa. Corrosion tests with coupons were performed using a ternary eutectic fluoride salt (FLiNaK) as the intermediate heat transfer fluid. While SiC is vulnerable to corrosion by the salt, the coating offers a high degree of protection to the ceramic substrate.

The censorship of death and dying has removed the “memento mori” practices, and in order to reintroduce this practice, some “Before I die” projects have been increasingly implemented. Running in parallel, in the syllabi of social service and psychology students, some experiences of death education has commenced. This study illustrates the results of a qualitative research conducted on the “Before I die I want to …” Polaroid® Project (BIDIWT), which is divided into two phases. The first phase entails an analysis of the wishes collected from the United States, Japan, India, and Italy. The second phase refers to the analysis of the captions of the BIDIWT realized from two groups of undergraduates, with regard to the effect of such experience on their religiosity, representation of death, and fear of death.

While analyzing currently available international research about embedded system development, it seems that as the complexity of embedded systems is continuously increasing, the major problems regarding their development remain always the same: vague requirements, insufficient time to develop, lack of resources, and complexity management. With the focus on the development process, it is shown, with examples coming from 20 years of experience, the industry perspective of a company managing such problems by adopting a consolidated set of good practices.

Armour systems based on ceramic materials offer excellent protection against armour piercing ammunition at significantly lower areal densities compared to conventional hard armour steel or aluminium. Their main disadvantages are the high costs of the commonly used monolithic ceramic tiles and the inadequate multi-hit performance. In the work presented, the manufacturing process, the physical properties and the ballistic behaviour of newly developed biomorphic SiSiC and C/SiSiC (Carbon fibre reinforced SiSiC) ceramics, based on wood powder and activated carbon, have been studied. All samples have been manufactured via the cost effective liquid silicon infiltration process (LSI) developed by DLR. The ballistic performance was studied on sample plates 100 mm x 100 mm with armour piercing ammunition (7.62 x 51 mm AP). The novel SiSiC materials have shown good single hit properties, whereas an increased damage tolerance was obtained by C/SiSiC materials.

Der am DLR in Stuttgart entwickelte LSI–Prozess bietet – unabhangig von der Bauteilgeometrie – eine relativ einfache Moglichkeit zur Herstellung von langfaserverstarkten keramischen Verbund¬werkstoffen auf der Basis von C/C-SiC. Aufgrund kundenspezifischer Anforderungen fur den Ein-satz in den mit Heisgas sowie mit schubfor¬dernden Aluminiumpartikeln beaufschlagten Bauteilen fur Raketenmotoren wurde ein fur die Serie tauglicher Prozess auf der Basis des Autoklav-Verfahrens entwickelt und erfolgreich zum Kunden transferiert. In diesem Beitrag konnte zudem gezeigt werden, dass der am DLR entwickelte Prozess zur Klein-serienproduktion von ca. 120 Strahlrudern mit hohen Qualitatsanforderungen erfolgreich eingesetzt werden konnte. Der Prozess erwies sich als sehr robust und aufgetretene Fehler konnten rasch be-hoben werden. Das ursprunglich in der Entwicklungsphase, festgelegte Biegefestigkeitsniveau von 160 – 200 MPa wurde mit 204,1 MPa im Kurzbiegeversuch sogar leicht uberschritten. Die Schwan-kungen in Festigkeit, aber auch offene Porositat und Dichte hielten sich in engen Grenzen. In CT-Untersuchungen konnten keine kritischen Fehler erkannt werden. Zukunftige High–Performance-Raketen sind ohne Komponenten auf der Basis von CMC (z.B.: C/C-SiC zur Schubvektorsteuerung) schwer zu realisieren. Des Weiteren ist die Integration alterna-tiver Techniken (Wickel- und Flechttechnik) im LSI-Prozess unabdingbar.

We have previously shown that the anti-apoptotic effects of Fingolimod (FIN), an FDA-approved agonist of sphingosine-1-P receptors (S1P-R), leads to reduced myocardial infarct (MI) size and improved systolic function in a pig model of ischemia-reperfusion. However, the effects of S1P-R activation on

A novel concept for hydrogen production has been reported by the US Department of Energy, which combines the use of heat from a nuclear power plant (a Generation IV reactor) or a solar power tower for the production of hydrogen in a thermo-chemical reaction. Ceramic heat exchangers (HX) provide a promising technology for this concept. Novel plate-type HXs with high power densities are proposed, which are based on novel integrated flow-channel designs. The main purpose of this study is the investigation of net-shape fabrication to prototypical HX components based on these designs. To achieve net-shape plates, dry powder mixtures were molded by axial pressing. The joining to the prototypical 3D HX stack was accomplished by lamination followed by pyrolysis at temperatures of up to 1650 °C. Due to the use of carbon fibers the shrinkage could be controlled and reduced to about 5 %. Finally, accurate silicon melt infiltration by using the wick method into the porous C/C preforms led to dense C/SiSiC ceramics. Microstructural investigations and flexural strength measurements were performed to demonstrate the homogeneity of the ceramic and the quality of the joinings. The gas-tightness of the ceramic composites to helium has been qualified by gas-leakage tests. Corrosion tests with C/SiSiC coupons, both with and without a CVD pyrocarbon-SiC protective coating (bilayer) were performed using a ternary eutectic fluoride salt of LiF, NaF, and KF (FLiNaK) as the intermediate heat transfer fluid. While SiC is vulnerable to corrosion by the salt, such a coating offers a high degree of protection to the ceramic substrate.
