Abstract

The First G-APD Cherenkov Telescope (FACT) is designed to detect cosmic gamma-rays with energies from several hundred GeV up to about 10 TeV using the Imaging Atmospheric Cherenkov Technique. In contrast to former or existing telescopes, the camera of the FACT telescope is comprised of solid-state Geiger-mode Avalanche Photodiodes (G-APD) instead of photomultiplier tubes for photo detection. It is the first full-scale device of its kind employing this new technology. The telescope is operated at the Observatorio del Roque de los Muchachos (La Palma, Canary Islands, Spain) since fall 2011. This paper describes in detail the design, construction and operation of the system, including hardware and software aspects. Technical experiences gained after one year of operation are discussed and conclusions with regard to future projects are drawn., Journal of Instrumentation, 8 (6), ISSN:1748-0221

Abstract

The discovery of very high energy (VHE) gamma-ray emitting X-ray binaries has triggered an intense effort to better understand the particle acceleration, absorption, and emission mechanisms in compact binary systems, which provide variable conditions along eccentric orbits. Despite this, the nature of some of these systems, and of the accelerated particles producing the VHE emission, is unclear. To answer some of these open questions, we conducted a multiwavelength campaign of the VHE gamma-ray emitting X-ray binary LS I +61 303 including the MAGIC telescope, XMM-Newton, and Swift during 60% of an orbit in 2007 September. We detect a simultaneous outburst at X-ray and VHE bands, with the peak at phase 0.62 and a similar shape at both wavelengths. A linear fit to the simultaneous X-ray/VHE pairs obtained during the outburst yields a correlation coefficient of r=0.97, while a linear fit to all simultaneous pairs provides r=0.81. Since a variable absorption of the VHE emission towards the observer is not expected for the data reported here, the correlation found indicates a simultaneity in the emission processes. Assuming that they are dominated by a single particle population, either hadronic or leptonic, the X-ray/VHE flux ratio favors leptonic models. This fact, together with the detected photon indices, suggests that in LS I +61 303 the X-rays are the result of synchrotron radiation of the same electrons that produce VHE emission as a result of inverse Compton scattering of stellar photons., To appear in The Astrophysical Journal Letters. 6 pages, 2 figures

Abstract

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

Abstract

14 páginas, 6 figuras, 4 tablas.-- El Pdf del artículo es la versión pre-print: arXiv:1002.2951v3.-- MAGIC Collaboration: et al., Between 2004 and 2009, a sample of 28 X-ray selected high- and intermediate-frequency peaked blazars with an X-ray flux larger than 2 μJy at 1 keV in the redshift range from 0.018 to 0.361 was observed with the MAGIC telescope at energies above 100 GeV. Seven among them were detected and the results of these observations are discussed elsewhere. Here we concentrate on the remaining 21 blazars which were not detected during this observation campaign and present the 3σ (99.7%) confidence upper limits on their flux. The individual flux upper limits lie between 1.6% and 13.6% of the integral flux from the Crab Nebula. Applying a stacking method to the sample of non-detections with a total of 394.1 hr exposure time, we find evidence for an excess with a cumulative significance of 4.9 standard deviations. It is not dominated by individual objects or flares, but increases linearly with the observation time as for a constant source with an integral flux level of ~1.5% of that observed from the Crab Nebula above 150 GeV., The support of the German BMBF and MPG, the Italian INFN, the Swiss National Fund SNF, and the Spanish MICINN is gratefully acknowledged. This work was also supported by the Polish MNiSzW Grant N N203 390834, by the YIP of the Helmholtz Gemeinschaft, and by grant DO02-353 of the the Bulgarian National Science Fund.

Abstract

Cygnus X-3 is a microquasar consisting of an accreting compact object orbiting around a Wolf-Rayet star. It has been detected at radio frequencies and up to high-energy gamma rays (above 100 MeV). However, many models also predict a very high energy (VHE) emission (above hundreds of GeV) when the source displays relativistic persistent jets or transient ejections. Therefore, detecting such emission would improve the understanding of the jet physics. The imaging atmospheric Cherenkov telescope MAGIC observed Cygnus X-3 for about 70 hours between 2006 March and 2009 August in different X-ray/radio spectral states and also during a period of enhanced gamma-ray emission. MAGIC found no evidence for a VHE signal from the direction of the microquasar. An upper limit to the integral flux for energies higher than 250 GeV has been set to 2.2 x 10-12 photons cm-2 s-1 (95% confidence level). This is the best limit so far to the VHE emission from this source. The non-detection of a VHE signal during the period of activity in the high-energy band sheds light on the location of the possible VHE radiation favoring the emission from the innermost region of the jets, where absorption is significant. The current and future generations of Cherenkov telescopes may detect a signal under precise spectral conditions., 14 pages, 11 figures, This manuscript has been accepted by ApJ (2010)

Abstract

5 páginas, 3 figuras, 1 tabla.-- El Pdf del artículo es la versión pre-print: arXiv:1010.0550.-- et al., We report new observations of the intermediate-frequency peaked BL Lacertae object 3C 66A with the MAGIC telescopes. The data sample we use were taken in 2009 December and 2010 January, and comprises 2.3 hr of good quality data in stereoscopic mode. In this period, we find a significant signal from the direction of the blazar 3C 66A. The new MAGIC stereoscopic system is shown to play an essential role for the separation between 3C 66A and the nearby radio galaxy 3C 66B, which is at a distance of only 6'. The derived integral flux above 100 GeV is 8.3% of the Crab Nebula flux and the energy spectrum is reproduced by a power law of photon index 3.64 ± 0.39stat ± 0.25sys. Within errors, this is compatible with the one derived by VERITAS in 2009. From the spectra corrected for absorption by the extragalactic background light, we only find small differences between the four models that we applied, and constrain the redshift of the blazar to z < 0.68., This work was also supported by the Marie Curie program, by the CPAN CSD2007-00042 and MultiDark CSD2009-00064 projects of the Spanish Consolider-Ingenio 2010 programme, by grant DO02-353 of the Bulgarian NSF, by grant 127740 of the Academy of Finland, by the YIP of the Helmholtz Gemeinschaft, by the DFG Cluster of Excellence “Origin and Structure of the Universe,” and by the Polish MNiSzW Grant N N203 390834.

Abstract

We report on the observation of the region around supernova remnant G65.1+0.6 with the stand-alone MAGIC-I telescope. This region hosts the two bright GeV gamma-ray sources 1FGL J1954.3+2836 and 1FGL J1958.6+2845. They are identified as GeV pulsars and both have a possible counterpart detected at about 35 TeV by the Milagro observatory. MAGIC collected 25.5 hours of good quality data, and found no significant emission in the range around 1 TeV. We therefore report differential flux upper limits, assuming the emission to be point-like (, 8 pages, 3 figures, 1 table

Abstract

We report on the detection with the MAGIC telescopes of very high energy gamma-rays from IC 310, a head-tail radio galaxy in the Perseus galaxy cluster, observed during the interval November 2008 to February 2010. The Fermi satellite has also detected this galaxy. The source is detected by MAGIC at a high statistical significance of 7.6sigma in 20.6 hr of stereo data. The observed spectral energy distribution is flat with a differential spectral index of -2.00 \pm 0.14. The mean flux above 300 GeV, between October 2009 and February 2010, (3.1 \pm 0.5)x10^{-12} cm^{-2} s^{-1}, corresponds to (2.5 \pm 0.4)% of Crab Nebula units. Only an upper limit, of 1.9% of Crab Nebula units above 300 GeV, was obtained with the 2008 data. This, together with strong hints (>3sigma) of flares in the middle of October and November 2009, implies that the emission is variable. The MAGIC results favour a scenario with the very high energy emission originating from the inner jet close to the central engine. More complicated models than a simple one-zone SSC scenario, e.g. multi-zone SSC, external Compton or hadronic, may be required to explain the very flat spectrum and its extension over more than three orders of magnitude in energy., 6 pages, 5 figures, submitted to ApJL

Abstract

Context: Part of the very high energy $��$-ray radiation coming from extragalactic sources is absorbed through the pair production process on the extragalactic background light photons. Extragalactic magnetic fields alter the trajectories of these cascade pairs and, in turn, convert cosmic background photons to gamma-ray energies by inverse Compton scattering. These secondary photons can form an extended halo around bright VHE sources. Aims: We searched for an extended emission around the bright blazars Mrk 421 and Mrk 501 using the MAGIC telescope data. Methods: If extended emission is present, the angular distribution of reconstructed gamma-ray arrival directions around the source is broader than for a point-like source. In the analysis of a few tens of hours of observational data taken from Mrk 421 and Mrk 501 we used a newly developed method that provides better angular resolution. This method is based on the usage of multidimensional decision trees. Comparing the measured shapes of angular distributions with those expected from a point-like source one can detect or constrain possible extended emission around the source. We also studied the influence of different types of systematic errors on the shape of the distribution of reconstructed gamma-ray arrival directions for a point source. Results: We present upper limits for an extended emission calculated for both sources for various source extensions and emission profiles. We discuss possible constraints on the extragalactic magnetic fields strength. We obtain upper limits on the extended emission around the Mrk~421 (Mrk~501) on the level of < 5% (< 4%) of the Crab Nebula flux above the energy threshold of 300 GeV. Using these results we discuss possible constraints on the extragalactic magnetic fields strength around a few times $10^{-15}$~G., 8 pages, 9 figures, accepted for publication in A&A

Abstract

International audience; The MAGIC collaboration has searched for high-energy gamma-ray emission of some of the most promising pulsar candidates above an energy threshold of 50 GeV, an energy not reachable up to now by other ground-based instruments. Neither pulsed nor steady gamma-ray emission has been observed at energies of 100 GeV from the classical radio pulsars PSR J0205+6449 and PSR J2229+6114 (and their nebulae 3C58 and Boomerang, respectively) and the millisecond pulsar PSR J0218+4232. Here, we present the flux upper limits for these sources and discuss their implications in the context of current model predictions.

Abstract

5 páginas, 2 figuras, 3 tablas.-- El Pdf del artículo es la versión pre-print: arXiv: arXiv:0911.1088.-- MAGIC Collaboration: et al., The blazar PG 1553+113 is a well known TeV γ-ray emitter. In this paper we determine its spectral energy distribution through simultaneous multi-frequency data to study its emission processes. An extensive campaign was carried out between March and April 2008, where optical, X-ray, high-energy (HE) γ-ray, and very-high-energy (VHE) γ-ray data were obtained with the KVA, Abastumani, REM, RossiXTE/ASM, AGILE and MAGIC telescopes, respectively. We combine the data to derive the source's spectral energy distribution and interpret its double-peaked shape within the framework of a synchrotron self-Compton model., Major support from Germany’s Bundesministerium f¨ur Bildung, Wissenschaft, Forschung und Technologie and Max-Planck-Gesellschaft, Italy’s Istituto Nazionale di Fisica Nucleare (INFN) and Istituto Nazionale di Astrofisica (INAF), and Spain’s Ministerio de Ciencia e Innovacion is gratefully acknowledged.

Abstract

10 páginas, 7 figuras, 6 tablas.-- El Pdf del artículo es la versión pre-print: arXiv:1001.1291.-- MAGIC Collaboration: et al., [Context]: Wide-range spectral coverage of blazar-type active galactic nuclei is of paramount importance for understanding the particle acceleration mechanisms assumed to take place in their jets. The Major Atmospheric Gamma Imaging Cerenkov (MAGIC) telescope participated in three multiwavelength (MWL) campaigns, observing the blazar Markarian (Mkn) 421 during the nights of April 28 and 29, 2006, and June 14, 2006. [Aims]: We analyzed the corresponding MAGIC very-high energy observations during 9 nights from April 22 to 30, 2006 and on June 14, 2006. We inferred light curves with sub-day resolution and night-by-night energy spectra. [Methods]: MAGIC detects γ-rays by observing extended air showers in the atmosphere. The obtained air-shower images were analyzed using the standard MAGIC analysis chain. [Results]: A strong γ-ray signal was detected from Mkn 421 on all observation nights. The flux (E > 250 GeV) varied on night-by-night basis between (0.92±0.11) × 10-10 cm-2 s-1 (0.57 Crab units) and (3.21±0.15) × 10-10 cm-2 s-1 (2.0 Crab units) in April 2006. There is a clear indication for intra-night variability with a doubling time of 36± min on the night of April 29, 2006, establishing once more rapid flux variability for this object. For all individual nights γ-ray spectra could be inferred, with power-law indices ranging from 1.66 to 2.47. We did not find statistically significant correlations between the spectral index and the flux state for individual nights. During the June 2006 campaign, a flux substantially lower than the one measured by the Whipple 10-m telescope four days later was found. Using a log-parabolic power law fit we deduced for some data sets the location of the spectral peak in the very-high energy regime. Our results confirm the indications of rising peak energy with increasing flux, as expected in leptonic acceleration models., The support of the German BMBF and MPG, the Italian INFN and Spanish MICINN is gratefully acknowledged.

Abstract

The Perseus galaxy cluster was observed by the MAGIC Cherenkov telescope for a total effective time of 24.4 hr during 2008 November and December. The resulting upper limits on the gamma-ray emission above 100 GeV are in the range of 4.6 to 7.5 x 10^{-12} cm^{-2} s^{-1} for spectral indices from -1.5 to -2.5, thereby constraining the emission produced by cosmic rays, dark matter annihilations, and the central radio galaxy NGC1275. Results are compatible with cosmological cluster simulations for the cosmic-ray-induced gamma-ray emission, constraining the average cosmic ray-to-thermal pressure to, 15 pages, 5 figures; accepted for publication in ApJ; updated to match the journal final version

Abstract

We report on the results of two coordinated multiwavelength campaigns that focused on the blazar Markarian 421 during its 2006 and 2008 outbursts. These campaigns obtained UV and X-ray data using the XMM-Newton satellite, while the gamma-ray data were obtained utilizing three imaging atmospheric Cerenkov telescopes, the Whipple 10m telescope and VERITAS, both based in Arizona, as well as the MAGIC telescope, based on La Palma in the Canary Islands. The coordinated effort between the gamma-ray groups allowed for truly simultaneous data in UV/X-ray/gamma-ray wavelengths during a significant portion of the XMM-Newton observations. This simultaneous coverage allowed for a reliable search for correlations between UV, X-ray and gamma-ray variability over the course of the observations. Investigations of spectral hysteresis and modeling of the spectral energy distributions are also presented., Comment: 27 pages, 5 figures, Accepted for publication in The Astrophysical Journal

Based on MAGIC observations from June and July 2007, we have obtained an integral upper limit to the VHE energy emission of the globular cluster M13 of $F(E>200 \textrm{GeV})140 \textrm{GeV}$. Those limits allow us to constrain the population of millisecond pulsars within M13 and to test models for acceleration of leptons inside their magnetospheres and surrounding. We conclude that in M13 either millisecond pulsars are fewer than expected or they accelerate leptons less efficiently than predicted.

Abstract

The accretion of matter onto a massive black hole is believed to feed the relativistic plasma jets found in many active galactic nuclei (AGN). Although some AGN accelerate particles to energies exceeding 10^12 electron Volts (eV) and are bright sources of very-high-energy (VHE) gamma-ray emission, it is not yet known where the VHE emission originates. Here we report on radio and VHE observations of the radio galaxy M87, revealing a period of extremely strong VHE gamma-ray flares accompanied by a strong increase of the radio flux from its nucleus. These results imply that charged particles are accelerated to very high energies in the immediate vicinity of the black hole., Comment: 21 pages, 5 figures, published in Science, see: http://www.sciencemag.org/cgi/content/abstract/325/5939/444

Abstract

Suzaku observations of the blazar OJ 287 were performed in 2007 April 10--13 and November 7--9. They correspond to a quiescent and a flaring state, respectively. The X-ray spectra can be well described with single power-law models in both exposures. The derived X-ray photon index and the flux density at 1 keV were found to be Gamma = 1.65 +- 0.02 and S_{1 keV} = 215 +- 5 nJy, in the quiescent state. In the flaring state, the source exhibited a harder X-ray spectrum (Gamma = 1.50 +- 0.01) with a nearly doubled X-ray flux density S_{1 keV} = 404^{+6}_{-5} nJy. Moreover, significant hard X-ray signals were detected up to ~ 27 keV. In cooperation with the Suzaku, simultaneous radio, optical, and very-high-energy gamma-ray observations were performed with the Nobeyama Millimeter Array, the KANATA telescope, and the MAGIC telescope, respectively. The radio and optical fluxes in the flaring state (3.04 +- 0.46 Jy and 8.93 +- 0.05 mJy at 86.75 Hz and in the V-band, respectively) were found to be higher by a factor of 2--3 than those in the quiescent state (1.73 +- 0.26 Jy and 3.03 +- 0.01 mJy at 86.75 Hz and in the V-band, respectively). No notable gamma-ray events were detected in either observation. The spectral energy distribution indicated that the X-ray spectrum was dominated by inverse Compton radiation in both observations, while synchrotron radiation exhibited a spectral cutoff around the optical frequency. Furthermore, no significant difference in the synchrotron cutoff frequency was found between the quiescent and flaring states. According to a simple synchrotron self-Compton model, the change of the spectral energy distribution is due to an increase in the energy density of electrons with small changes of both the magnetic field strength and the maximum Lorentz factor of electrons., 22 pages, 8 figures; accepted for publication in PASJ

Abstract

Background and Aims: Risks of peri- and postoperative complications after bowel surgery in patients with inflammatory bowel disease (IBD) receiving biologics are still discussed controversially. We therefore addressed the safety of different biologics that were applied in our IBD center before surgery., Methods: Data of IBD patients who underwent bowel resections between 2012 and 2022 at our hospital were analyzed retrospectively. Exposure to biologics was defined by receiving biologics within 12 weeks before resective abdominal surgery. Safety considerations included minor complications, such as infections and wound healing disorders and major complications, e.g., anastomotic insufficiency or abscess formation., Results: A total of 447 IBD patients (334 with Crohn's disease, 113 with ulcerative colitis), 51.9% female, were included and followed for a median follow-up of 45 months [range 0-113]. A total of 73.9% (326/447) were undergoing medical treatment at date of surgery, 61.5% (275/447) were treated with biologics within 3 months and 42.3% (189/447) within 4 weeks before surgery. Most surgeries (97.1%) were planned electively and 67.8% were performed laparoscopically. Major and minor complications occurred in 20.8% (93/447) of patients. Serious complications were rare: Six patients had acute postoperative bleeding, one CD patient developed peritonitis and two CD patients died postoperatively. After adjusting for age, disease duration, disease activity, Montreal classification, and medical treatment at date of surgery, no significant differences were observed regarding complications and exposure to biologics., Conclusions: This retrospective single center study of 447 IBD patients goes to demonstrate that perioperative use of biologics is not associated with a higher risk of complications., Competing Interests: • T.

Abstract

Bridging the gap between genetic variations, environmental determinants, and phenotypic outcomes is critical for supporting clinical diagnosis and understanding mechanisms of diseases. It requires integrating open data at a global scale. The Monarch Initiative advances these goals by developing open ontologies, semantic data models, and knowledge graphs for translational research. The Monarch App is an integrated platform combining data about genes, phenotypes, and diseases across species. Monarch's APIs enable access to carefully curated datasets and advanced analysis tools that support the understanding and diagnosis of disease for diverse applications such as variant prioritization, deep phenotyping, and patient profile-matching. We have migrated our system into a scalable, cloud-based infrastructure; simplified Monarch's data ingestion and knowledge graph integration systems; enhanced data mapping and integration standards; and developed a new user interface with novel search and graph navigation features. Furthermore, we advanced Monarch's analytic tools by developing a customized plugin for OpenAI's ChatGPT to increase the reliability of its responses about phenotypic data, allowing us to interrogate the knowledge in the Monarch graph using state-of-the-art Large Language Models. The resources of the Monarch Initiative can be found at monarchinitiative.org and its corresponding code repository at github.com/monarch-initiative/monarch-app., (© The Author(s) 2023.

Abstract

Institutional transference is a phenomenon describing patients' attitudes toward the institutions where they receive mental health or medical care. While transference toward individual clinicians in palliative care has been described, attitudes of patients with serious illness toward the institutions where they receive specialized care have not been described. Here, we present three cases which demonstrate the phenomenon of institutional transference in patients with serious illness and the resulting clinical implications, which include countertransferential responses of clinicians caring for them. We consider three conditions: (1) the idealized reputation of the academic cancer center, often a tertiary referral center; (2) loss of an institutional connection during care transitions; and (3) countertransferential reactions to institutional transference. We highlight characteristics and personality styles of individuals with cancer that may complicate and intensify institutional transference and identify potential interventions to address common challenges associated with institutional transference.

Abstract

Purpose: An increasing number of adolescents and young adults (AYA) are becoming cancer survivors and are dealing with long-term effects of the disease and its treatment. We aimed to collect detailed self-reported information about the areas of work, education, and the financial situation of AYA survivors after acute treatment. We further examined sources of support that were perceived as particular helpful., Method: We conducted semi-structured interviews with a sample of 11 AYA cancer survivors (on average 5 years from diagnosis; mean age at diagnosis = 25.7 years) that had been recruited for the AYA-Leipzig longitudinal study. Interviews were transcribed and data were analysed using qualitative content analysis., Results: The following themes emerged as relevant: (1) career modifications and job loss, (2) career interruptions and delays, (3) uncertainty in the return-to-work process, (4) reduced work ability, (5) discrimination at the workplace, (6) changes in the personal importance of work and (7) financial burdens. Sources of considerable support included relatives as well as German social security institutions., Conclusions: Health care providers should address the specific risk of a financial burden and the somewhat complex social legal situation of young adult survivors after cancer diagnosis. AYA cancer survivors need age-specific comprehensive cancer survivorship support programs. These should accompany them in the long term and be targeted to the individual need for career modification or reorientation - even after the completion of cancer treatment and rehabilitation., Competing Interests: Declaration of competing interest None declared., (Copyright © 2023 Elsevier Ltd.

Abstract

These NCCN Guidelines for Distress Management discuss the identification and treatment of psychosocial problems in patients with cancer. All patients experience some level of distress associated with a cancer diagnosis and the effects of the disease and its treatment regardless of the stage of disease. Clinically significant levels of distress occur in a subset of patients, and identification and treatment of distress are of utmost importance. The NCCN Distress Management Panel meets at least annually to review comments from reviewers within their institutions, examine relevant new data from publications and abstracts, and reevaluate and update their recommendations. These NCCN Guidelines Insights describe updates to the NCCN Distress Thermometer (DT) and Problem List, and to the treatment algorithms for patients with trauma- and stressor-related disorders.

Abstract

Purpose: Evidence suggests that patients with cancer frequently use cannabis with medicinal intent and desire clinical guidance from providers. We aimed to determine whether oncology training adequately prepares fellows to discuss medical cannabis., Methods: A national survey study was conducted from January to March 2021. A questionnaire assessing oncology fellows' practices regarding cannabis recommendations in cancer care and their knowledge of its effectiveness and risks compared with conventional care for cancer-related symptoms was developed and sent to 155 US-based oncology training programs to distribute to trainees., Results: Forty programs from 25 states participated; of the 462 trainees across these programs, 189 responded (response rate of 40%). Of the participants, 52% were female; 52% were White, 33% Asian, and 5% Hispanic. Fifty-seven percent reported that they discussed medical cannabis with more than five patients in the preceding year; however, only 13% felt sufficiently informed to issue cannabis-related clinical recommendations. Twenty-four percent reported having received formal training regarding medical cannabis. Oncology fellows who reported having received prior training in medical cannabis were significantly more likely to discuss cannabis with patients (risk ratio: 1.37, 95% CI 1.06 to 1.75; P = .002) and feel sufficiently informed to discuss cannabis recommendations (risk ratio: 5.06; 95% CI, 2.33 to 10.99; P < .001). Many viewed the botanical as a useful adjunctive therapy that was at least as effective as conventional treatments for anorexia/cachexia (72%), nausea/vomiting (45%), and pain (41%)., Conclusion: Most oncology trainees not only reported engaging in discussions regarding medical cannabis with patients but also considered themselves insufficiently informed to make cannabis-related clinical recommendations. The discrepancy between the frequency of cannabis inquiries/discussions at the patient level and comfort/knowledge at the trainee provider level represents an unmet curricular need with implications for both graduate medical education and patient care.
