Which adults aged 65 and older are at low-risk for cervical spine injuries after low-level falls?

Objectives: The population is aging and falls are a common reason for emergency department visits. Appropriate imaging in this population is important. The objectives of this study were to estimate the prevalence of cervical spine injury and identify factors associated with cervical spine injuries in adults ≥ 65 years after low-level falls.

Temporal Trends in Spinal Imaging in Ontario (2002-2019) and Manitoba (2001-2011), Canada.

Background Several studies have reported the overuse of spinal imaging, which, in Canada, led to several provincial pathways aimed at optimizing the use of imaging. We assessed temporal trends in spine imaging in two Canadian provinces. Methods We explored the use of X-ray, computed tomography (CT), and magnetic resonance imaging (MRI) examinations of the cervical, thoracic, and lumbar spine regions among adults in Ontario (April 1, 2002, to March 31, 2019) and in Manitoba, Canada (April 1, 2001, to March 31, 2011) using linked Ontario Health Insurance Plan administrative databases and data from Manitoba Health.

Emergency physician gender and head computed tomography orders for older adults who have fallen.

Objective: Physicians vary in their computed tomography (CT) scan usage. It remains unclear how physician gender relates to clinical practice or patient outcomes. The aim of this study was to assess the association between physician gender and decision to order head CT scans for older emergency patients who had fallen.

Derivation of the Falls Decision Rule to exclude intracranial bleeding without head CT in older adults who have fallen.

Background: Ground-level falls are common among older adults and are the most frequent cause of traumatic intracranial bleeding. The aim of this study was to derive a clinical decision rule that safely excludes clinically important intracranial bleeding in older adults who present to the emergency department after a fall, without the need for a computed tomography (CT) scan of the head.

Methods: This prospective cohort study in 11 emergency departments in Canada and the United States enrolled patients aged 65 years or older who presented after falling from standing on level ground, off a chair or toilet seat, or out of bed.

Desmoplastic small round cell tumor involving the uterine cervix: The first reported case in the literature, and brief review of gynecologic presentations.

Background: Desmoplastic small round cell tumors are exceedingly rare, usually involve abdominal organs and predominantly affect male patients. We describe the first reported case arising from the uterine cervix and provide a summary of 20 previously reported cases involving gynecologic organs.

Case: A 54 year-old was diagnosed with a rapidly growing 13 cm desmoplastic small round cell tumor of the cervix.

Pancreatic Cystic Lesions on MRI: What Is The Likelihood of a Present or Future Diagnosis of Pancreatic Carcinoma?

Background: Pancreatic cystic lesions (PCLs) are followed for years due to older and likely biased works demonstrating a strong association with pancreatic carcinoma; more recent data are needed clarifying this relationship.

Purpose: To determine the association between PCLs on MRI and a synchronous or future diagnosis of pancreatic carcinoma.

Study Type: Single-center retrospective cohort.

CAR Peer Learning Guide.

Peer learning is a quality initiative used to identify potential areas of practice improvement, both on a patient level and on a systemic level. Opportunities for peer learning include review of prior imaging studies, evaluation of cases from multidisciplinary case conferences, and review of radiology trainees' call cases. Peer learning is non-punitive and focuses on promoting life-long learning.

Radiologist Productivity Analytics: Factors Impacting Abdominal Pelvic CT Exam Reporting Times.

The purpose is to determine factors impacting radiologist abdominal pelvic CT exam reporting time. This study was Research Ethics Board approved. Between January 2019 and March 2020, consecutive abdominal pelvic CT exams were documented as structured or unstructured based on application of templates with separate sections for different organs or organ systems.

Lessons learned from radiology mentors.

As in any field, radiologists may face a number of challenges as they navigate their early careers. Because with experience comes wisdom, early-career radiologists may find helpful the advice and perspectives of mid- and late-career radiologists. The Society of Abdominal Radiology recognizes the value of this pool of knowledge and experience, prompting the establishment of the Early Career Committee.

Which older emergency patients are at risk of intracranial bleeding after a fall? A protocol to derive a clinical decision rule for the emergency department.

Introduction: Falling on level ground is now the most common cause of traumatic intracranial bleeding worldwide. Older adults frequently present to the emergency department (ED) after falling. It can be challenging for clinicians to determine who requires brain imaging to rule out traumatic intracranial bleeding, and often head injury decision rules do not apply to older adults who fall.

Which Aspects of the CanMEDS Competencies are Most Valued in Radiologists? Perspectives of Trainees From Other Specialties.

Purpose: Radiologists work primarily in collaboration with other healthcare professionals. As such, these stakeholder perspectives are of value to the development and assessment of educational outcomes during the transition to competency-based medical education. Our aim in this study was to determine which aspects of the Royal College CanMEDS competencies for diagnostic radiology are considered most important by future referring physicians.

MRI LI-RADS Version 2018: Impact of and Reduction in Ancillary Features.

The purpose of this study is to determine the impact of LI-RADS ancillary features on MRI and to ascertain whether the number of ancillary features can be reduced without compromising LI-RADS accuracy. A total of 222 liver observations in 81 consecutive patients were identified on MRI between August 2013 and December 2018. The presence or absence of major and ancillary features was used to determine the LI-RADS category for LR-1 to LR-5 observations.

Using Online Survey Software to Enhance Radiology Learning.

Rationale And Objectives: Online educational modules can augment radiology learning by creating opportunities to interact with images in more dynamic ways than with static presentation of images in lectures or journal articles. Building these modules on an online survey platform allows for quantitative assessment and learner feedback, without requiring programming knowledge or need for new website creation.

Materials And Methods: Interactive online tutorials were built on a web-based survey platform (Qualtrics, Provo, Utah) accessible by computer or mobile device to teach radiology imaging findings of selected high-morbidity diagnoses.

MRI vs. CT for the Detection of Liver Metastases in Patients With Pancreatic Carcinoma: A Comparative Diagnostic Test Accuracy Systematic Review and Meta-Analysis.

Background: The detection of liver metastases is important for pancreatic cancer curative treatment eligibility. The data suggest that magnetic resonance imaging (MRI) is more sensitive than computed tomography (CT) for the diagnosis of pancreatic cancer liver metastases. However, MRI is not currently recommended in multiple published guidelines.

Incidence of intracranial bleeding in seniors presenting to the emergency department after a fall: A systematic review.

Introduction: Seniors who fall are an increasing proportion of the patients who are treated in emergency departments (ED). Falling on level-ground is the most common cause of traumatic intracranial bleeding. We aimed to determine the incidence of intracranial bleeding among all senior patients who present to ED after a fall.

Improving and Maintaining Radiologic Technologist Skill Using a Medical Director Partnership and Technologist Coaching Model.

Objective: Consistent excellence in radiologic technologist performance, including ensuring high technical image quality, patient safety and comfort, and efficient workflow, largely depends on individual technologist skill. However, sustained growth in the size and complexity of health care organizations has increased the difficulty in developing and maintaining technologist expertise. In this article, we explore underlying organizational structures that contribute to this problem and propose organizational models to promote continued excellence in technologist skill.

Computed Tomography of Internal Hernias Following Laparoscopic Roux-en-Y Gastric Bypass Surgery.

Internal hernia in the postoperative laparoscopic Roux-en-Y patient is a diagnosis associated with significant morbidity and risk of death. The radiologist plays an instrumental role in workup of this patient group; however, the imaging assessment of these patients is not straightforward given their complex postsurgical anatomy. Multiple radiologic signs of internal hernia have been studied in the literature.

The impact of deep vein thrombosis in critically ill patients: a meta-analysis of major clinical outcomes.

Background: Critically ill patients appear to be at high risk of developing deep vein thrombosis (DVT) and pulmonary embolism during their stay in the intensive care unit (ICU). However, little is known about the clinical course of venous thromboembolism in the ICU setting. We therefore evaluated, through a systematic review of the literature, the available data on the impact of a diagnosis of DVT on hospital and ICU stay, duration of mechanical ventilation and mortality in critically ill patients.

Surgical waste audit of 5 total knee arthroplasties.

Background: Operating rooms (ORs) are estimated to generate up to one-third of hospital waste. At the London Health Sciences Centre, prosthetics and implants represent 17% of the institution's ecological footprint. To investigate waste production associated with total knee arthroplasties (TKAs), we performed a surgical waste audit to gauge the environmental impact of this procedure and generate strategies to improve waste management.

Reporting of the estimated glomerular filtration rate decreased creatinine clearance testing.

The Kidney Disease Outcomes Quality Initiative (K/DOQI) guidelines suggest that clinicians use the estimated glomerular filtration rate (eGFR) measurements and minimize the use of timed urine creatinine clearance collection. The intent of this change was to improve recognition of chronic kidney disease. Here we used time-series modeling and intervention analyses to determine the effect of publication of the K/DOQI guidelines and the introduction of widespread eGFR reporting with prompts on physician ordering of 24-h urine collection for creatinine clearance.

Impact of estimated GFR reporting on patients, clinicians, and health-care systems: a systematic review.

Background: Many laboratories now report estimated glomerular filtration rate (eGFR) when a serum creatinine measurement is ordered. A summary of the impact of eGFR reporting in health care systems around the world for which it has been adopted is lacking.

Study Design: Systematic review of MEDLINE, EMBASE, other major databases, and conference proceedings of major nephrology meetings.

Integrating polyurethane culture substrates into poly(dimethylsiloxane) microdevices.

Poly(dimethylsiloxane) (PDMS)-based microdevices have enabled rapid, high-throughput assessment of cellular response to precisely controlled microenvironmental stimuli, including chemical, matrix and mechanical factors. However, the use of PDMS as a culture substrate precludes long-term culture and may significantly impact cell response. Here we describe a method to integrate polyurethane (PU), a well-studied and clinically relevant biomaterial, into the PDMS multilayer microfabrication process, enabling the exploration of long-term cellular response on alternative substrates in microdevices.

Use of antifibrinolytic therapy to reduce transfusion in patients undergoing orthopedic surgery: a systematic review of randomized trials.

Background: Minimizing bleeding and transfusion is desirable given its cost, complexity and potential for adverse events. Concerns have been heightened by recent data demonstrating that bleeding events may predict worse outcomes and by warnings about the safety of erythropoietic stimulating agents. Prior small studies suggest that antifibrinolytic agents may reduce bleeding and transfusion need in patients undergoing total hip replacement (THR) or total knee arthroplasty (TKA).
