The COVID-19 pandemic has foisted unprecedented changes upon graduate medical education ranging from adjustments to patient care practices to adaptive modifications to educational activities. To comply with social distancing guidelines, in-person conferences and didactics have been suspended in most, if not all residency programs throughout the country. Many programs, however, have transitioned to live virtual platforms such as Zoom to continue educational activities. While live virtual learning has allowed for continued education, it presents its unique challenges. The impersonal nature of the virtual learning environment creates a propensity for detachment and disengagement. While the video function is turned off and the microphone is muted, a participant can completely disengage from virtual learning while still appearing to be present.Ultrasound elastography (USE) is becoming an important adjunct tool in the evaluation of various musculoskeletal (MSK) traumatic conditions and diseases, with an increasing number of applications and publications in recent years. This rapidly evolving technique enhances the conventional ultrasound (US) examination by providing information on the elastic properties of tissue alongside the morphological and vascular information obtained from B-mode US and Doppler imaging. Those performing USE must have basic knowledge of its proper imaging techniques and limitations. In this review article, we place the USE in historical perspective and discuss basic techniques and current applications of USE in the evaluation of various traumatic and pathologic conditions of fasciae, nerves, muscles, tendons, ligaments, and MSK soft tissue masses.At the outset and during the throes of the COVID-19 pandemic, as valuable resources are channeled to combat the pandemic, challenges in timely delivery of non-COVID-19-related health care services such as endovascular service arise. As such, this article looks at a tertiary institution's experience in managing its endovascular workload-referenced to the American College of Surgeons' triage of vascular surgery patient acuity-based case classification.Erdheim-Chester disease (ECD), a rare non-Langerhans cell histiocytosis, involves multiple systems and may display pericardial effusion. Herein, we report a 60-year-old man who presented with refractory pericardial effusion of "unknown" etiology. As in this patient, ECD should be considered when rapidly recurrent pericardial effusion is accompanied by a pseudotumoral lesion of the right atrium and other systemic manifestations.The University of British Columbia (UBC) Faculty of Medicine suspended clinical rotations for medical students on March 14, 2020 due to the COVID-19 pandemic. At that time 291 Year 3 medical students were engaged in clerkships across British Columbia and urgently needed an academic pathway to advance to Year 4 on schedule.Hematopoiesis refers to the developmental process generating all blood lineages. In vertebrates, there are multiple waves of hematopoiesis, which emerge in distinct anatomic locations at different times and give rise to different blood lineages. In the last decade, numerous lineage-tracing studies have been conducted to investigate the hierarchical structure of the hematopoietic system. Yet, the majority of these lineage-tracing studies are not able to integrate the spatial-temporal information with the developmental potential of hematopoietic cells. With the newly developed infrared laser-evoked gene operator (IR-LEGO) microscope heating system, it is now possible to improve our understanding of hematopoiesis to spatial-temporal-controlled single-cell resolution. Here, we discuss the recent development of the IR-LEGO system and its applications in hematopoietic lineage tracing in vivo.During the COVID-19 pandemic, transplant recipients have been recognized as more susceptible to infection, to have greater severity of disease, and prolonged shedding of this highly transmissible virus.1 However, there is limited information on the impact of COVID-19 in liver transplant (LT) recipients. We reviewed three reported cases with detailed treatment information from China to better understand the features and associated therapeutic strategies used in transplant recipients with COVID-19.2-4.The current COVID-19 pandemic is a challenge to every health system over the globe. Unfortunately, it is likely that this emergency will not disappear soon. No health system, with its present resources and work flow is ready to deal with a full-blown wave of this pandemic. Rapid acquisition of specific new skills may be fundamental in delivering appropriate health care for our patients. COVID-19 infection is classically diagnosed by real time reverse transcription polymerase chain reaction and radiological investigations (X-ray or high-resolution computerized tomography). These techniques are not without limitations. Ultrasound has been suggested as a reliable and accurate tool for assessing the lungs in patients with suspected pneumonia. β-Nicotinamide Obstetricians and gynecologists are usually familiar with the use of ultrasound. Lung ultrasound can show specific signs of interstitial pneumonia, which is characteristic of COVID-19 pulmonary infection. We believe that extensive and rapid training of healthcare providers on the application of ultrasound in the detection of characteristic pulmonary signs of COVID-19 infection, in addition to proper care and handling of their ultrasound machines, is feasible and may be critical in order to provide appropriate management especially of the obstetric patient in the coming period. We present a systematic approach to lung examination, simplified to encourage its adoption by obstetricians and gynecologists, together with an example of a recent pregnant woman with COVID-19 infection, in which lung ultrasound was useful in the management.Our previous study revealed that expression of G protein-coupled receptor 68 (GPR68) was upregulated in MDSL cells, a cell line representing myelodysplastic syndromes (MDS), in response to lenalidomide (LEN), and mediated a calcium/calpain proapoptotic pathway. Isx, a GPR68 agonist, enhanced the sensitivity to LEN in MDSL cells. The fact that Isx is not a U.S. Food and Drug Administration-approved drug prompts us to look for alternative candidates that could enhance the sensitivity of LEN in MDS as well as other hematologic malignancies, such as acute myeloid leukemia (AML). In the study described here, we found that regulator of calcineurin 1 (RCAN1), an endogenous inhibitor of calcineurin (CaN), was upregulated in MDSL cells in response to LEN, possibly through degradation of IKZF1. Consistently, cyclosporin (Cys), a pharmacological inhibitor of CaN, inhibited the activity of CaN and induced apoptosis in MDSL cells, indicating that CaN provided a prosurvival signal in MDSL cells. In addition, Cys enhanced the cytotoxic effect of LEN in MDS/AML cell lines as well as primary bone marrow cells from MDS patients and AML patient-derived xenograft models.
