Monthly notices of the Royal Astronomical Society 465(3), 3767 - 3774 (2017). doi:10.1093/mnras/stw3032, The absorption of TeV $\gamma$-ray photons produced in relativistic jets by surrounding soft photon fields is a long-standing problem of jet physics. In some cases, the most likely emission site close to the central black hole is ruled out because of the high opacity caused by strong optical and infrared photon sources, such as the broad-line region. Mostly neglected for jet modelling is the absorption of $\gamma$-rays in the starlight photon field of the host galaxy. Analysing the absorption for arbitrary locations and observation angles of the $\gamma$-ray emission site within the host galaxy, we find that the distance to the galaxy centre, the observation angle, and the distribution of starlight in the galaxy are crucial for the amount of absorption. We derive the absorption value for a sample of 20 TeV-detected blazars with a redshift $z_r$ < 0.2. The absorption value of the $\gamma$-ray emission located in the galaxy centre may be as high as 20 per cent, with an average value of 6 per cent. This is important in order to determine the intrinsic blazar parameters. We see no significant trends in our sample between the degree of absorption and host properties, such as starlight emissivity, galactic size, half-light radius, and redshift. While the uncertainty of the spectral properties of the extragalactic background light exceeds the effect of absorption by stellar light from the host galaxy in distant objects, the latter is a dominant effect in nearby sources. It may also be revealed in a differential comparison of sources with similar redshifts., Published by Oxford Univ. Press, Oxford

Although case series suggest a higher burden of cardiovascular risk factors in patients with systemic lupus erythematosus (SLE) compared with the general population, the association between SLE and heart failure (HF) remains undefined. We sought to investigate the incidence and risk of HF in patients with SLE.In April 2016, we performed a retrospective cohort analysis using the Explorys platform, which provides aggregated electronic medical record data from 26 major integrated healthcare systems across the USA from 1999 to present. Demographic and regression analyses were performed to assess the impact of SLE on HF incidence.Among 45 284 540 individuals in the database, we identified 95 400 (0.21%) with SLE and 98 900 (0.22%) with a new diagnosis of HF between May 2015 and April 2016. HF incidence was markedly higher in the SLE group compared with controls (0.97% vs 0.22%, relative risk (RR): 4.6 (95% CI 4.3 to 4.9)), as were other cardiovascular risk factors. In regression analysis, SLE was an independent predictor of HF (adjusted OR: 3.17 (2.63 to 3.83), p0.0001). RR of HF was highest in young males with SLE (65.2 (35.3 to 120.5) for age 20-24), with an overall trend of increasing absolute risk but decreasing RR with advancing age in both sexes. Renal involvement in SLE correlated with earlier and higher incidence of HF.The findings of this study suggest that patients with SLE have significantly higher risk of developing HF and a worse cardiovascular risk profile compared with the general population. These results need to be confirmed by prospective studies.

Introduction The current literature reports a 10-40% occurrence rate of right ventricular (RV) failure after left ventricular assist device (LVAD) implantation. We assessed our institution's incidence of RV failure after LVAD implantation to determine specific predictive values for developing RV failure after LVAD implantation. Methods We conducted a retrospective analysis of patients who underwent LVAD implantation from 2013 to 2019 at a single academic hospital. RV failure was defined according to the INTERMACS definition, with elevated central venous pressure (CVP) documented by right atrial pressure > 16mmHg, and manifestations of elevated CVP including renal dysfunction, or elevated bilirubin. Based on the duration of inotropes, severity of RV failure was further risk stratified as mild ( 14 days). Preoperative demographic, hemodynamic, echocardiographic and laboratory characteristics were identified amongst each group. Using patients without RV failure as the control arm, comparisons were made with independent two sample t-tests and multivariate analysis. Results Between 2013 to 2019, there were a total of 136 LVAD implantations at our institution in which 22.1% were as bridge to transplant, and 77.9% as destination therapy. RV failure was diagnosed in 44.1% of patients, in which 14.7% were categorized as mild, 17.7% as moderate, and 11.8% as severe. Preoperative parameters that predicted RV failure after LVAD implantation included right atrial pressure (RAP) > 10mmHg (RR: 1.58, 95% CI: 1.08 to 2.32, p=0.0174), preoperative renal dysfunction with BUN > 20 mg/dL (RR: 2.22, 95% CI: 1.45 to 3.41, p=0.0003) or Cr > 1.3 mg/dL (RR: 1.83, 95% CI: 1.28 to 2.63, p = 0.001) and total bilirubin > 1.5mg/dL (RR: 1.73, 95% CI: 1.21 to 2.46, p=0.0025). Conclusions Postoperative RV failure is a common occurrence after LVAD implantation. We identified that patients with elevated CVP, renal dysfunction and elevated total bilirubin pre operatively are at higher risk for developing RV failure after LVAD, and these patients should have a low threshold for RV support at the time of LVAD surgery.

The supernova remnant (SNR) W49B originated from a core-collapse supernova that occurred between one and four thousand years ago, and subsequently evolved into a mixed-morphology remnant, which is interacting with molecular clouds (MC). $\gamma$-ray observations of SNR/MC associations are a powerful tool to constrain the origin of Galactic cosmic-rays, as they can probe the acceleration of hadrons through their interaction with the surrounding medium and subsequent emission of non-thermal photons. The detection of a $\gamma$-ray source coincident with W49B at very high energies (VHE; E > 100 GeV) with the H.E.S.S. Cherenkov telescopes is reported together with a study of the source with 5 years of Fermi-LAT high energy $\gamma$-ray (0.06 - 300 GeV) data. The smoothly-connected combined source spectrum, measured from 60 MeV to multi-TeV energies, shows two significant spectral breaks at $304\pm20$ MeV and $8.4_{-2.5}^{+2.2}$ GeV, the latter being constrained by the joint fit from the two instruments. The detected spectral features are similar to those observed in several other SNR/MC associations and are found to be indicative of $\gamma$-ray emission produced through neutral-pion decay., Comment: 10 pages, 6 figures.

The Automatic Telescope for Optical Monitoring is a 75cm optical telescope located at the H.E.S.S. site in Namibia. Since 2005, it monitors around 250 gamma-ray emitting AGN and has observed numerous blazar flares in several colour bands with multiple measurements during any given night. We present recent flaring events of two FSRQ – 3C 279 and CTA 102 – together with corresponding multi-wavelength data including Fermi-LAT, and examine possible correlations between energy bands.

The flat spectrum radio quasar (FSRQ) PKS 1510-089 (z=0.361) is known for its complex multiwavelength behavior. It has been monitored regularly at very high energy (VHE, $E>100\,$GeV) gamma-rays with H.E.S.S. since its discovery in 2009 in order to study the unknown behavior of FSRQs in quiescence at VHE, as well as the flux evolution around flaring events. Given the expected strong cooling of electrons and the absorption of VHE emission within the broad-line region, a detection of PKS 1510-089 at VHE in a quiescent state would be an important result, implying an acceleration and emission region on scales beyond the broad-line region. The H.E.S.S. monitoring has been intensified since 2015 and is complemented by monitoring at high energy ($E>100\,$MeV) gamma-rays with Fermi, at X-rays with Swift-XRT, and at optical frequencies with ATOM. The dense lightcurves allow for the first time detailed comparison studies between these energy bands. The source has been active in several frequency bands for a large fraction of the observation time frames. Yet, we do not find obvious correlations between the VHE and the other bands over the observed time frame indicating a non-trivial interplay of the acceleration, cooling and radiative processes. It also implies a rich variety in flaring behavior, which makes this source difficult to interpret within a unique theoretical framework., To appear in Proceedings of 35th ICRC, Busan (Korea) 2017

Rapid blazar flaring events and their rich behavior require time-dependent modeling. One important approach is time-dependent injection causing non-linear cooling effects, since the inevitable SSC cooling depends on the time-dependent electron distribution function γ˙∝∫γ2n(γ,t)dγ. This results in a collective and faster energy loss of the electrons in the jet, which could explain the extremely short variability times. The most obvious result of the non-linear cooling is the appearance of unique breaks in the time-integrated SED, which would normally be attributed to a complicated electron distribution. The knowledge of the observation time is important to interpret the observed spectra, because of the non-trivial evolution of the time-dependent SED. Intrinsic gamma-gamma absorption processes in the emission region are only of minor importance.

Monthly notices of the Royal Astronomical Society 469(4), 4465 – 4482 (2017). doi:10.1093/mnras/stx1098, We report on the discovery of a new fast radio burst (FRB), FRB 150215, with the Parkes radio telescope on 2015 February 15. The burst was detected in real time with a dispersion measure (DM) of 1105.6 ± 0.8 pc cm$^{−3}$, a pulse duration of 2.8 $^{+1.2}_{-0.5}$ ms, and a measured peak flux density assuming that the burst was at beam centre of 0.7$^{+0.2}_{-0.1}$ Jy. The FRB originated at a Galactic longitude and latitude of 24.66°, 5.28° and 25° away from the Galactic Center. The burst was found to be 43 ± 5 per cent linearly polarized with a rotation measure (RM) in the range −9, Published by Oxford Univ. Press, Oxford

Most modeling attempts of blazars use a small emission zone located close to the central black hole in order to explain the broad-band spectral energy distribution. Here we present a case where additionally to the small region a $>$kpc-scale jet is required to successfully reproduce the spectrum and especially the TeV emission, namely the low-frequeny peaked BL Lac object AP Librae detected in the TeV domain by the H.E.S.S. experiment. Given that other parts of the spectral energy distribution follow the characteristics implied by the source classification, the inverse Compton component spans 10 orders of magnitude, which cannot be reproduced by the one-zone model. Additionally, observational constraints in both the synchrotron and inverse Compton compoenent strongly constrain the parameters of a self-consistent model ruling out the possibility of TeV photon production in the vicinity of the galactic center. We discuss the possibility that the TeV radiation is emitted by highly energetic particles in the extended, arcsec-scale jet, which has been detected at radio and X-ray energies. The slope of the jet X-ray spectrum indicates an inverse Compton origin, and an extrapolation to higher energies coincides with a break feature in the $\gamma$-ray band. Modeling the jet emission with inverse Compton scattering of the cosmic microwave background results in an excellent fit of the radio, X-ray and TeV emission. Implications will be discussed, such as properties of the jet, acceleration scenarios, and observations to test the model. If confirmed, large scale jets are able to efficiently accelerate particles and to keep relativistic speeds up to distances of several 100kpc., Comment: 5 pages, 1 figure, to appear in the AIP Conference proceedings of the "High Energy Gamma-Ray Astronomy (Gamma2016)", edited by F.

Blazars exhibit flares with a doubling time scale on the order of minutes. Such rapid flares are theoretically challenging and several {models} have been put forward to explain the fast variability. In this paper we continue the discussion concerning the effects of non-linear, time-dependent synchrotron self-Compton (SSC) cooling. In previous papers we were able to show that the non-linearity{, introduced by a time-dependent electron injection,} has severe consequences for both the spectral energy distribution (SED) and the monochromatic synchrotron light curve. The non-linear cooling introduces novel breaks in the SED, which are usually explained by complicated underlying electron distributions, while the much faster cooling of the SSC process {causes significant differences in the synchrotron light curves}. In this paper we calculate the inverse Compton light curves, taking into account both the SSC and the external Compton process. The light curves are calculated from the monochromatic intensities by introducing the retardation due to the finite size of the emission region and the geometry of the source. Even though some of the obvious effects of the SSC cooling are washed out by the retardation, there are still several observational constraints which could help to discriminate between the non-linear and the usual linear models, such as different flux states, temporal shapes or faster variability of the light curves at different energies., Comment: 23 pages, 5 figures, accepted for publication in MNRAS

Introduction Seasonal influenza vaccine is recommended in heart transplant patients. While it is typically well tolerated, there have been reports of low level histologic rejections . The influenza vaccine itself has been linked to inflammatory myopathies and has also been implicated in a case of myocarditis in a previously healthy individual . We present the first suspected case of myocarditis after influenza vaccine in a heart transplant patient. Case Report A 30-year-old African-American male with familial cardiomyopathy status post heart transplantation 18 months ago developed recurrent significant left ventricular dysfunction. Immediately post transplantation, he had acute graft dysfunction without evidence of acute cellular or antibody mediated rejection and negative donor specific antibodies. He received steroids, IVIG and plasmapheresis with restoration of graft function. 16 moths post-transplant, he had acute cellular rejection in the setting of subtherapeutic tacrolimus levels and was treated with pulse dose steroids with resolution. At 18 months, his EF dropped from 55-60% to 30-35% with a low cardiac index of 1.8, felt to be secondary to a non HLA antibodies given a negative endomyocardial biopsy. Pulse dose steroids resulted in recovery of his LV function by cardiac MRI (LVEF 52%). As part of his care he received the seasonal influenza vaccine. 3 weeks later he presented with dyspnea and fatigue. An echocardiogram at that time showed an ejection fraction of 35-40%. EMB was negative for rejection. A repeat cardiac MRI showed acute myocarditis. Although the EMB was negative for myocarditis, the sensitivity would have increased if a sample from the left ventricle was obtained. Summary This is the first case of a heart transplant patient with suspected acute myocarditis after receiving the influenza vaccine. Although alternative diagnoses cannot be excluded, the proximity of the vaccine and imaging evidence supports a direct correlation.

Introduction Acute kidney injury is common in patients with cardiogenic shock supported with extracorporeal membrane oxygenation (ECMO), and it is associated with mortality. Hypothesis We hypothesized that mortality is not different between patients who require early (within 48 hours) vs late (≥48 hours of ECMO) initiation of continuous renal replacement therapy (CRRT). Methods We retrospectively reviewed all patients with cardiogenic shock who underwent veno-arterial ECMO at University Hospitals, between 2015 and 2018. Patients who required CRRT during ECMO support were divided into early vs late CRRT initiation. Inpatient mortality, one-year mortality and length of stay were compared between the two patient groups. Results Out of 127 patients supported with ECMO, 56 (44%) required CRRT (40 early and 16 late CRRT). Among patients requiring CRRT, mean age was 57±14 years, 74% were male, median SAVE score was -9 [-14, -5], and median lactate was 7.6 [4.2, 12.4] mmol/L. There were no statistically-significant differences in baseline characteristics (demographics, comorbidities, laboratory values, or hemodynamic measurements) between early and late CRRT (P>0.05 for all comparisons). There were no statistically-significant differences between early and late CRRT with respect to inpatient mortality (62% vs 64%, P>0.99), 1-year mortality (78% vs 67%, P=0.71) or length of stay (median 20 vs 16 days, P=0.61). There was no association between time of CRRT and risk of inpatient mortality (OR 1.00, 95% CI: 0.88-1.15, P=0.95), or one-year mortality (HR 0.96, 9% CI: 0.89-1.05, P=0.39). Conclusions Mortality is high among patients who require CRRT during ECMO support. There was no difference between early (

Purpose The Model of End-Stage Liver Disease (MELD) score incorporates measures of kidney and liver dysfunction . MELD score has been shown to predict mortality in patients with advanced heart failure or cardiogenic shock (CS). Prior small single-center studies have shown that MELD score predicts mortality in patients supported with Venoarterial Extracorporeal Membrane Oxygenation (VA-ECMO). The Purpose of our was to reassess the role of MELD score predicting Mortality After (VA-ECMO). Methods We reviewed 105 consecutive patients with (CS) who received VA-ECMO between 8/2014 and 6/2018 in our hospital. We calculated MELD, MELD excluding INR (MELDXI), MELD with sodium -MELDNa- (calculated at a mean of 7 hours prior to VA-ECMO initiation), and SAVE score. We identified the association between each score and short-term mortality using logistic regression and Kaplan-Meier with Cox proportional hazard models . Results Our patient had Mean age was 57.1 ± 13.8 years and 32% female. Mean MELD score was 19.5 ± 8.3, MELDXI 18.9 ± 7.1, MELDNa 20.5 ± 8.3, SAVE -8.6 ± 6.5. Inpatient mortality was 68%. SAVE score was associated with short-term (OR 0.91 per 1 unit, 95% CI: 0.84-0.98, P=0.011) and long-term mortality (HR 0.95, 95% CI: 0.91-0.98, P=0.002) (Figure 1). There was no association between MELD (OR 1.02, 95% CI: 0.97-1.08, P=0.41), MELDXI (OR 1.01, 95% CI: 0.95-1.07, P=0.86), or MELDNa (OR 1.02, 95% CI: 0.97-1.08, P=0.41), with inpatient mortality. MELD (OR 1.07, 1.01-1.13, P=0.02), MELDXI (OR 1.12 [1.05-1.20], P=0.001) and MELDNa (OR 1.06, 95% CI: 1.01-1.12, P=0.03) were all associated with need for hemodialysis after ECMO. Conclusion In this single-center study of patients with VA ECMO, neither MELD, nor MELDXI or MELDNa, were associated with short-term or long-term mortality. SAVE score was able to modestly predict inpatient mortality. Further studies are needed to delineate the impact of bystander organ dysfunction to predict mortality in patients supported with VA-ECMO.

The flat spectrum radio quasar CTA 102 ($z = 1.032$) went through a tremendous phase of variability. Since early 2016 the gamma-ray flux level has been significantly higher than in previous years. It was topped by a four month long giant outburst, where peak fluxes were more than 100 times higher than the quiescence level. Similar trends are observable in optical and X-ray energies. We have explained the giant outburst as the ablation of a gas cloud by the relativistic jet that injects additional matter into the jet and can self-consistently explain the long-term light curve. Here, we argue that the cloud responsible for the giant outburst is part of a larger system that collides with the jet and is responsible for the years-long activity in CTA 102., 9 pages, 5 figures, accepted by Galaxies as part of the special issue "Monitoring the non-thermal Universe", a conference held in Cochem, Germany, 17th - 21st September 2018

Valvular disease is common in patients undergoing left ventricular assist device (LVAD) implantation. Concomitant valve surgery increases procedural complexity and cardiopulmonary bypass time and may lead to worse outcomes.1 Although mitral regurgitation is the most common mitral valve dysfunction in patients undergoing LVAD implantation, mitral stenosis (MS) is occasionally encountered. MS can lead to restricted LVAD flow; therefore, mitral valve replacement is considered to be reasonable in patients with hemodynamically significant MS undergoing LVAD implantation. We describe a successful transcatheter mitral valve replacement (TMVR) via a transapical approach with concomitant LVAD implantation in a patient with bioprosthetic MS. Our patient is a 67-year-old male with ischemic cardiomyopathy, stage D heart failure with reduced ejection fraction, and left ventricular ejection fraction 15%. He had prior 6-vessel coronary artery bypass grafting, bioprosthetic mitral valve replacement (Medtronic Mosaic porcine mitral valve, 29-mm size) for severe mitral regurgitation, and a modified endoventricular circular patch plasty (Dor procedure) for left ventricular aneurysm repair. He had cardiac resynchronization therapy and defibrillator therapy and was paced 99% but remained symptomatic with low output symptoms, as confirmed by hemodynamic assessment. By the time of referral to our institution, he had been hospitalized multiple times in the preceding 6 months with acutely decompensated heart failure, severe ascites, and malnutrition and was maintained on home inotropic therapy with Milrinone at …

The blazar PKS 1510-089 was the first of the flat spectrum radio quasar type, which had been detected simultaneously by a ground based Cherenkov telescope (H.E.S.S.) and the LAT instrument on board the Fermi satellite. Given the strong broad line region emission defining this blazar class, and the resulting high optical depth for VHE ($E>100\,$GeV) $\gamma$-rays, it was surprising to detect VHE emission from such an object.

Persons living with HIV are at a higher risk of cardiovascular disease despite effective antiretroviral therapy and dramatic reductions in AIDS-related conditions. We sought to identify the epidemiology of heart failure (HF) among persons living with HIV in the United States in an era of contemporary antiretroviral therapy.Explorys is an electronic healthcare database that aggregates medical records from 23 healthcare systems nationwide. Using systemized nomenclature of medicine-clinical terms (SNOMED-CT), we identified adult patients (age18), who had active records over the past year (September 2014-September 2015). We described the prevalence of HF in HIV patients by demographics and treatment and compared them to HIV-uninfected controls.Overall, there were 36,400 patients with HIV and 12,208,430 controls. The overall prevalence of HF was 7.2% in HIV and 4.4% in controls (RR 1.66 [1.60-1.72], p0.0001). The relative risk of HF associated with HIV infection was higher among women and younger age groups. Patients receiving antiretroviral therapy had only marginally lower risk (6.4% vs. 7.7%, p0.0001) of HF compared to those who were untreated. Compared to uninfected patients with HF, HIV patients with HF were less likely to receive antiplatelet drugs, statins, diuretics, and ACE/ARBs (p0.0001 for all comparisons). For patients with HIV and HF, receiving care from a cardiologist was associated with higher use of antiplatelets, statins, betablockers, ACE/ARBs, and diuretics.Persons with HIV are at higher risk for HF in this large contemporary sample that includes both men and women. Although the prevalence of heart failure is higher in older HIV patients, the relative risk associated with HIV is highest in young people and in women. HIV patients are less likely to have HF optimally treated, but cardiology referral was associated with higher treatment rates.

The low-frequency peaked BL Lac object (LBL) AP Librae exhibits very-high-energy (VHE, $E>100$GeV) $\gamma$-ray emission and hosts an extended jet, which has been detected in radio and X-rays. The jet X-ray spectral index implies an inverse Compton origin. These observations are unusual for LBLs calling for a consistent explanation of this extraordinary source. The observationally constrained parameters necessary to describe the core emission within the standard one-zone model are unable to explain the broad-band spectrum, even if observationally unconstrained external photon fields are taken into account. We demonstrate that the addition of the extended jet emission successfully reproduces the total spectral energy distribution. In particular, the VHE radiation is produced in the $>100\,$kpc long extended jet via inverse Compton scattering of cosmic microwave background photons by highly relativistic electrons. We present several ways to test this theory. The extended jet is weakly magnetized ($B_0 = 2.5\,\mu$G), while its minimum and maximum electron Lorentz factors are $\gamma_{min}=60$ and $\gamma_{max}=5\times 10^6$, respectively. The electron spectral index is $s=2.6$. These parameters are comparable to parameters of other blazars with extended X-ray jets dominated by inverse Compton scattering., Comment: 12 pages, 6 figures.

The massive binary system Eta Carinae and the surrounding HII complex, the Carina Nebula, are potential particle acceleration sites from which very-high-energy (VHE; E > 100 GeV) \gamma-ray emission could be expected. This paper presents data collected during VHE \gamma-ray observations with the H.E.S.S. telescope array from 2004 to 2010, which cover a full orbit of Eta Carinae. In the 33.1-hour data set no hint of significant \gamma-ray emission from Eta Carinae has been found and an upper limit on the \gamma-ray flux of 7.7 x 10-13 ph cm-2 s-1 (99% confidence level) is derived above the energy threshold of 470 GeV. Together with the detection of high-energy (HE; 0.1 GeV > E > 100 GeV) \gamma-ray emission by the Fermi-LAT up to 100 GeV, and assuming a continuation of the average HE spectral index into the VHE domain, these results imply a cut-off in the \gamma-ray spectrum between the HE and VHE \gamma-ray range. This could be caused either by a cut-off in the accelerated particle distribution or by severe \gamma-\gamma\ absorption losses in the wind collision region. Furthermore, the search for extended \gamma-ray emission from the Carina Nebula resulted in an upper limit on the \gamma-ray flux of 4.2 x 10-12 ph cm-2 s-1 (99% confidence level). The derived upper limit of ~23 on the cosmic-ray enhancement factor is compared with results found for the old-age mixed-morphology supernova remnant W 28.

The broad-band SEDs of blazars exhibit two broad spectral components, which in leptonic emission models are attributed to synchrotron radiation and synchrotron self-Compton (SSC) radiation of relativistic electrons. During high-state phases, the high-frequency SSC component often dominates the low-frequency synchrotron component, implying that the inverse-Compton SSC losses of electrons are at least equal to or greater than the synchrotron losses of electrons. We calculate from the analytical solution of the kinetic equation of relativistic electrons, subject to the combined linear synchrotron and non-linear SSC cooling, for monoenergetic injection the time-integrated total synchrotron and SSC radiation fluences and spectral energy distributions (SEDs). Depending on the ratio of the initial cooling terms, displayed by the injection parameter α, we find for α≪ 1, implying complete linear cooling, that the synchrotron peak dominates the inverse-Compton peak and the usual results of the spectra are recovered. For α≫ 1, the SSC peak dominates the synchrotron peak, proving our assumption that in such a case the cooling becomes initially non-linear. The spectra also show some unique features, which can be attributed directly to the non-linear cooling. To show the potential of the model, we apply it to outbursts of 3C 279 and 3C 454.3, successfully reproducing the SEDs. The results of our analysis are promising, and we argue that this non-equilibrium model should be considered in future modelling attempts for blazar flares.

BACKGROUND: Type 2 diabetes is an important risk factor for heart failure and is common among patients with heart failure. The impact of weight on prognosis after hospitalization for acute heart failure among patients with diabetes is unknown. The objective of this study was to examine all-cause mortality in relation to weight status among patients with type 2 diabetes hospitalized for decompensated heart failure. METHODS: The Worcester Heart Failure Study included adults admitted with acute heart failure to all metropolitan Worcester medical centers in 1995 and 2000. The weight status of 1644 patients with diabetes (history of type 2 diabetes in medical record or admission serum glucose 200 mg/dL) was categorized using body mass index calculated from height and weight at admission. Survival status was ascertained at 1 and 5 years after hospital admission. RESULTS: Sixty-five percent of patients were overweight or obese and 3% were underweight. Underweight patients had 50% higher odds of all-cause mortality within 5 years of hospitalization for acute heart failure than normal weight patients. Class I and II obesity were associated with 20% and 40% lower odds of dying. Overweight and Class III obesity were not associated with mortality. Results were similar for mortality within 1 year of hospitalization for acute heart failure. CONCLUSIONS: The mechanisms underlying the association between weight status and mortality are not fully understood. Additional research is needed to explore the effects of body composition, recent weight changes, and prognosis after hospitalization for heart failure among patients with diabetes.

Background Kidney and liver dysfunction are common in patients with advanced heart failure undergoing left ventricular assistant device (LVAD) implantation. We have previously shown that Model of End-Stage Liver Disease excluding INR (MELD-XI) scores can predict poor outcomes after heart transplantation. Whether MELD-XI predicts outcomes after LVAD implantation is not well understood. Methods All patients who underwent LVAD implantation at a tertiary referral center (2007-2017) were included and preoperative MELD-XI was calculated. Cox proportional hazard models and Kaplan Meier method were used to describe association with overall post-implant mortality. Penalized smoothed splines were used to visualize the association between continuous MELDXI and mortality. Results A total of 94 patients were included. Mean age was 60±13 years, 78% males, 64% Caucasian, 76% had the HeartMate II. Median MELD-XI was 12.4(9.9-15.9). At a median follow-up of 2.8 years, 31 patients died. There was no difference between patients with MELD-XI >12.4 and MELD-XI ≤12.4 in overall mortality ( P =0.14), figure (panel A). There was no association between continuous MELD-XI and mortality (HR 1.04; 95% CI: 0.96-1.13, P =0.32), figure (panel B). Conclusion Our findings showed that MELD-XI is not associated with mortality after LVAD implantation. These findings need to be validated in a larger group registry to identify best bridging strategy in patients with advanced heart failure and combined kidney-liver dysfunction.

In late 2016 and early 2017 the flat spectrum radio quasar CTA 102 exhibited a very strong and long-lasting outburst. The event can be described by a roughly 2 months long increase of the baseline flux in the monitored energy bands (optical to $\gamma$ rays) by a factor 8, and a subsequent decrease over another 2 months back to pre-flare levels. The long-term trend was superseded by short but very strong flares, resulting in a peak flux that was a factor 50 above pre-flare levels in the $\gamma$-ray domain and almost a factor 100 above pre-flare levels in the optical domain. In this paper we explain the long-term evolution of the outburst by the ablation of a gas cloud penetrating the relativistic jet. The slice-by-slice ablation results in a gradual increase of the particle injection until the center of the cloud is reached, after which the injected number of particles decreases again. With reasonable cloud parameters we obtain excellent fits of the long-term trend., Comment: 9 pages, 5 figures; accepted for publication in The Astrophysical Journal

Context. In powerful cosmic nonthermal radiation sources with a dominant magnetic field self generation, partition between the energy densities in magnetic fields and relativistic electrons is expected. As the electrons cool by synchrotron emission, the magnetic field strength becomes time-dependent and adjusts itself to the actual kinetic energy density of the radiating electrons. Aims. For the case of instantaneous injection of power law distributed electrons with a flat power law spectral index, the nonlinear synchrotron fluence is calculated. Methods. Results. For flat (spectral index 1 < s < 2) injected power laws the nonlinear synchrotron fluence at small frequencies approaches a power law ∝v ―0.6 , independent of the value of s, which is identical to the synchrotron fluence behaviour for steep injected power laws.

Monthly notices of the Royal Astronomical Society 446(2), 1163 - 1169 (2015). doi:10.1093/mnras/stu2148, The region around the supernova remnant (SNR) W41 contains several TeV sources and has prompted the HESS Collaboration to perform deep observations of this field of view. This resulted in the discovery of the new very high energy (VHE) source HESS J1832−093, at the position $RA=18^{h}32^{m}50^{s} \pm 3^{s}_{stat}\pm2^{s}_{syst},Dec=−9^\circ22^{\prime} 36^{\prime\prime} \pm 32^{\prime\prime}_{stat} \pm 20^{\prime\prime}_{syst}(J2000)$, spatially coincident with a part of the radio shell of the neighbouring remnant G22.7−0.2. The photon spectrum is well described by a power law of index Γ = 2.6 $\pm$ 0.3$_{stat}$ $\pm$ 0.1$_{syst}$ and a normalization at 1 TeV of Φ$_{0}=(4.8 \pm 0.8_{stat} \pm 1.0_{syst}) ×10^{−13}cm^{−2}s^{−1}TeV^{−1}$. The location of the gamma-ray emission on the edge of the SNR rim first suggested a signature of escaping cosmic rays illuminating a nearby molecular cloud. Then a dedicated XMM–Newton observation led to the discovery of a new X-ray point source spatially coincident with the TeV excess. Two other scenarios were hence proposed to identify the nature of HESS J1832−093. Gamma-rays from inverse Compton radiation in the framework of a pulsar wind nebula scenario or the possibility of gamma-ray production within a binary system are therefore also considered. Deeper multiwavelength observations will help to shed new light on this intriguing VHE source., Published by Oxford Univ. Press, Oxford

Dwarf spheroidal galaxies of the Local Group are close satellites of the Milky Way characterized by a large mass-to-light ratio and are not expected to be the site of non-thermal high-energy gamma-ray emission or intense star formation. Therefore they are amongst the most promising candidates for indirect dark matter searches. During the last years the High Energy Stereoscopic System (H.E.S.S.) of imaging atmospheric Cherenkov telescopes observed five of these dwarf galaxies for more than 140 hours in total, searching for TeV gamma-ray emission from annihilation of dark matter particles. The new results of the deep exposure of the Sagittarius dwarf spheroidal galaxy, the first observations of the Coma Berenices and Fornax dwarves and the re-analysis of two more dwarf spheroidal galaxies already published by the H.E.S.S. Collaboration, Carina and Sculptor, are presented. In the absence of a significant signal new constraints on the annihilation cross-section applicable to Weakly Interacting Massive Particles (WIMPs) are derived by combining the observations of the five dwarf galaxies. The combined exclusion limit depends on the WIMP mass and the best constraint is reached at 1-2 TeV masses with a cross-section upper bound of ~3.9x10-24 cm^3 s-1 at a 95% confidence level., Comment: to be published in Physical Review D journal; Contact authors: E.

In this paper the optical depths in blazars due to photo-pair production is calculated for a time-dependent, non-linear injection model. Several target photon fields are taken into account, namely the internal synchrotron, synchrotron-self Compton and external Compton radiation, as well as a constant external soft photon field. By applying the optical depths to theoretical blazar spectra only the constant external photon field turns out to significantly influence the radiation at high energies. The impact of the internal time-dependent radiation fields is either minor or requires extreme parameter settings. Additionally, the synchrotron-self absorption turn-over energy for low synchrotron energies is calculated, which is inherently time-dependent. It would be challenging to use it to constrain free parameters, since precise knowledge of the observation time relative to the injection time is needed. In conclusion, optical depth does not significantly influence the non-linear, time-dependent injection and cooling model., accepted by MNRAS, 14 pages, 7 figures

The non-thermal nature of the X-ray emission from the shell-type supernova remnants (SNRs) G1.9+0.3 and G330.2+1.0 is an indication of intense particle acceleration in the shock fronts of both objects. This suggests that the SNRs are prime candidates for very-high-energy (VHE; E $>$ 0.1 TeV) {\gamma}-ray observations. G1.9+0.3, recently established as the youngest known SNR in the Galaxy, also offers a unique opportunity to study the earliest stages of SNR evolution in the VHE domain. The purpose of this work is to probe the level of VHE {\gamma}-ray emission from both SNRs and use this to constrain their physical properties. Observations were conducted with the H.E.S.S. (High Energy Stereoscopic System) Cherenkov telescope array over a more than six-year period spanning 2004-2010. The obtained data have effective livetimes of 67 h for G1.9+0.3 and 16 h for G330.2+1.0. The data are analyzed in the context of the multi-wavelength observations currently available and in the framework of both leptonic and hadronic particle acceleration scenarios. No significant {\gamma}-ray signal from G1.9+0.3 or G330.2+1.0 was detected. Upper limits (99% confidence level) to the TeV flux from G1.9+0.3 and G330.2+1.0 for the assumed spectral index {\Gamma} = 2.5 were set at 5.6 $\times$ 10$^{-13}$ cm$^{-2}$ s$^{-1}$ above 0.26 TeV and 3.2 $\times$ 10$^{-12}$ cm$^{-2}$ s$^{-1}$ above 0.38 TeV, respectively. In a one-zone leptonic scenario, these upper limits imply lower limits on the interior magnetic field to B$_{\mathrm{G1.9}}$ $\gtrsim$ 11 {\mu}G for G1.9+0.3 and to B$_{\mathrm{G330}}$ $\gtrsim$ 8 {\mu}G for G330.2+1.0. In a hadronic scenario, the low ambient densities and the large distances to the SNRs result in very low predicted fluxes, for which the H.E.S.S. upper limits are not constraining., Comment: 9 pages, 2 figures, 4 tables.

Diffuse $\gamma$-ray emission is the most prominent observable signature of celestial cosmic-ray interactions at high energies. While already being investigated at GeV energies over several decades, assessments of diffuse $\gamma$-ray emission at TeV energies remain sparse. After completion of the systematic survey of the inner Galaxy, the H.E.S.S. experiment is in a prime position to observe large-scale diffuse emission at TeV energies. Data of the H.E.S.S. Galactic Plane Survey are investigated in regions off known $\gamma$-ray sources. Corresponding $\gamma$-ray flux measurements were made over an extensive grid of celestial locations. Longitudinal and latitudinal profiles of the observed $\gamma$-ray fluxes show characteristic excess emission not attributable to known $\gamma$-ray sources. For the first time large-scale $\gamma$-ray emission along the Galactic Plane using imaging atmospheric Cherenkov telescopes has been observed. While the background subtraction technique limits the ability to recover modest variation on the scale of the H.E.S.S. field of view or larger, which is characteristic of the inverse Compton scatter-induced Galactic diffuse emission, contributions of neutral pion decay as well as emission from unresolved $\gamma$-ray sources can be recovered in the observed signal to a large fraction. Calculations show that the minimum $\gamma$-ray emission from $\pi^0$-decay represents a significant contribution to the total signal. This detection is interpreted as a mix of diffuse Galactic $\gamma$-ray emission and unresolved sources., Comment: 8 pages, 2 figures, accepted for publication in Physical Review D

The results of follow-up observations of the TeV gamma-ray source HESSJ 1640-465 from 2004 to 2011 with the High Energy Stereoscopic System (H.E.S.S.) are reported in this work. The spectrum is well described by an exponential cut-off power law with photon index Gamma=2.11 +/- 0.09_stat +/- 0.10_sys, and a cut-off energy of E_c = (6.0 +2.0 -1.2) TeV. The TeV emission is significantly extended and overlaps with the north-western part of the shell of the SNR G338.3-0.0. The new H.E.S.S. results, a re-analysis of archival XMM-Newton data, and multi-wavelength observations suggest that a significant part of the gamma-ray emission from HESS J1640-465 originates in the SNR shell. In a hadronic scenario, as suggested by the smooth connection of the GeV and TeV spectra, the product of total proton energy and mean target density could be as high as W_p n_H ~ 4 x 10^52 (d/10kpc)^2 erg cm^-3., accepted for publication in MNRAS, 9 pages, 5 figures, added Spitzer citation and acknowledgement

The Cherenkov Telescope Array (CTA) is a new observatory for very high-energy (VHE) gamma rays. CTA has ambitions science goals, for which it is necessary to achieve full-sky coverage, to improve the sensitivity by about an order of magnitude, to span about four decades of energy, from a few tens of GeV to above 100 TeV with enhanced angular and energy resolutions over existing VHE gamma-ray observatories. An international collaboration has formed with more than 1000 members from 27 countries in Europe, Asia, Africa and North and South America. In 2010 the CTA Consortium completed a Design Study and started a three-year Preparatory Phase which leads to production readiness of CTA in 2014. In this paper we introduce the science goals and the concept of CTA, and provide an overview of the project., La lista completa de autores puede consultarse en el documento o en la página web de la revista., Facultad de Ingeniería

Gamma-ray line signatures can be expected in the very-high-energy (VHE; E_\gamma > 100 GeV) domain due to self-annihilation or decay of dark matter (DM) particles in space. Such a signal would be readily distinguishable from astrophysical \gamma-ray sources that in most cases produce continuous spectra which span over several orders of magnitude in energy. Using data collected with the H.E.S.S. \gamma-ray instrument, upper limits on line-like emission are obtained in the energy range between ~500 GeV and ~25 TeV for the central part of the Milky Way halo and for extragalactic observations, complementing recent limits obtained with the Fermi-LAT instrument at lower energies. No statistically significant signal could be found. For monochromatic \gamma-ray line emission, flux limits of (2x10^-7 - 2x10^-5) m^-2 s^-1 sr^-1 and (1x10^-8 - 2x10^-6) m^-2 s^-1 sr^-1 are obtained for the central part of the Milky Way halo and extragalactic observations, respectively. For a DM particle mass of 1 TeV, limits on the velocity-averaged DM annihilation cross section < \sigma v >(\chi\chi -> \gamma\gamma) reach ~10^-27 cm^3 s^-1, based on the Einasto parametrization of the Galactic DM halo density profile., Comment: 6 pages, 4 figures, accepted for publication in Phys.

A deep observation campaign carried out by the High Energy Stereoscopic System (H.E.S.S.) on Centaurus A enabled the discovery of gamma rays from the blazar 1ES 1312-423, two degrees away from the radio galaxy. With a differential flux at 1 TeV of (1.9 +/-0.6(stat) +/-0.4(sys)) x 10^{-13} /cm^2 /s /TeV corresponding to 0.5% of the Crab nebula differential flux and a spectral index of 2.9 +/- 0.5 (stat) +/- 0.2 (sys), 1ES 1312-423 is one of the faintest sources ever detected in the very high energy (E>100 GeV) extragalactic sky. A careful analysis using three and a half years of Fermi-LAT data allows the discovery at high energies (E>100 MeV) of a hard spectrum (index of 1.4 +/- 0.4 (stat) +/- 0.2 (sys)) source coincident with 1ES 1312-423. Radio, optical, UV and X-ray observations complete the spectral energy distribution of this blazar, now covering 16 decades in energy. The emission is successfully fitted with a synchrotron self Compton model for the non-thermal component, combined with a black-body spectrum for the optical emission from the host galaxy., 12 pages, 10 figures, accepted in MNRAS

Blazars emit non-thermal radiation in all frequency bands from radio to \gamma-rays. Additionally, they often exhibit rapid flaring events at all frequencies with doubling time scale of the TeV and X-ray flux on the order of minutes, and such rapid flaring events are hard to explain theoretically. We explore the effect of the synchrotron-self Compton cooling, which is inherently time-dependent, leading to a rapid cooling of the electrons. Having discussed intensively the resulting effects of this cooling scenario on the spectral energy distribution of blazars in previous papers, the effects of the time-dependent approach on the synchrotron lightcurve are investigated here. Taking into account the retardation due to the finite size of the source and the source geometry, we show that the time-dependent synchrotron-self Compton (SSC) cooling still has profound effects on the lightcurve compared to the usual linear (synchrotron and external Compton) cooling terms. This is most obvious if the SSC cooling takes longer than the light crossing time scale. Then in most frequency bands the variability time scale is up to an order of magnitude shorter than under linear cooling conditions. This is yet another strong indication that the time-dependent approach should be taken into account for modeling blazar flares from compact emission regions., Comment: Accepted by The Astrophysical Journal, 11pages, 5 figures
