Measuring response to treatment in axial spondyloarthritis using quantitative imaging biomarkers: a prospective observational cohort study.

Objective: Objective assessments of disease activity and response to treatment in axial spondyloarthritis (axSpA) remain a challenge; quantitative imaging biomarkers (QIBs) of inflammation could enhance assessments of disease activity and therapeutic response. We aimed to determine the responsiveness of QIBs obtained from diffusion-weighted imaging (DW-MRI) and chemical shift-encoded MRI (CSE-MRI) using the partially automated Bone Edema and Adiposity Characterisation with Histograms (BEACH) software tool in axSpA patients undergoing biologic therapy.

Methods: We conducted a prospective longitudinal cohort study, including 30 patients with axSpA undergoing biologic therapy.

Assessment of body composition and association with clinical outcomes in patients with lung and colorectal cancer.

Objectives: To assess body composition in patients with non-small cell lung cancer (NSCLC) and colorectal cancer using whole-body MRI and relate this to clinical outcomes.

Methods: 53 patients with NSCLC (28 males, 25 females; mean age 66.9) and 74 patients with colorectal cancer (42 males, 32 females; mean age 62.

Fat fraction mapping using magnetic resonance imaging: insight into pathophysiology.

Adipose cells have traditionally been viewed as a simple, passive energy storage depot for triglycerides. However, in recent years it has become clear that adipose cells are highly physiologically active and have a multitude of endocrine, metabolic, haematological and immune functions. Changes in the number or size of adipose cells may be directly implicated in disease (e.

Impact of Hospital-Employed Physician Assistants on a Level II Community-Based Orthopaedic Trauma System.

Objectives: The American Academy of Orthopedic Surgeons and the Orthopedic Trauma Association have released guidelines for the provision of orthopedic trauma services such as adequate stipends, designated operating rooms, ancillary staff, and guaranteed reimbursement for indigent care. One recommendation included a provision for hospital-based physician assistants (PAs). Given current reimbursement arrangements, PA collections for billable services may not meet their salary and benefit expenses.

Operating Room Efficiency: Benefits of an Orthopaedic Traumatologist at a Level II Trauma Center.

Objectives: Fellowship-trained orthopaedic traumatologists are presumably taught skill sets leading to "best practice" outcomes and more efficient use of hospital resources. This should result in more favorable economic opportunities when compared with general orthopaedic surgeons (GOSs) providing similar clinical services. The purpose of our study was to compare the operating room utilization and financial data of traumatologists versus GOSs at a level II trauma center.

Discordant inflammatory changes in the apophyseal and sacroiliac joints: serial observations in enthesitis-related arthritis.

Objective: To determine the extent to which inflammation of the sacroiliac joints (SIJs) and apophyseal joints (AJs) changes concordantly after treatment in enthesitis-related arthritis (ERA).

Methods: A retrospective study was performed with institutional review board approval. 31 young patients with ERA who had been scanned between March 2009 and November 2014 were included.

Outcomes after plating of olecranon fractures: A multicenter evaluation.

Introduction: The aim of this study was to report the physical and functional outcomes after open reduction internal fixation of the olecranon in a large series of patients with region specific plating across multiple centres.

Patients/methods: Between January 2007 and January 2014, 182 consecutive patients with a displaced olecranon fracture treated with open reduction internal fixation were included in this study. Retrospective review across four trauma centres collected elbow range of motion, DASH scores, hardware complications, and hardware removal.

Venous infarction mimicking a neoplasm in spontaneous intracranial hypotension: an unusual cause of Parinaud's syndrome.

We present a case of longstanding, undiagnosed spontaneous intracranial hypotension (SIH) with an acute presentation of Parinaud's syndrome, in whom serial imaging demonstrated development of a midbrain mass. The patient was ultimately diagnosed with tumefactive venous infarction secondary to SIH. However, this patient underwent a brainstem biopsy, which in retrospect may have been avoidable.

Association of the apparent diffusion coefficient with maturity in adolescent sacroiliac joints.

Purpose: To determine the extent to which apparent diffusion coefficient (ADC) values vary with skeletal maturity in adolescent joints.

Materials And Methods: A retrospective study was performed with Institutional Review Board (IRB) approval. We used a picture archiving and communication system (PACS) search to identify and recruit all adolescents who had undergone 1.

A diffusion-based quantification technique for assessment of sacroiliitis in adolescents with enthesitis-related arthritis.

Objective: To investigate the use of a quantitative diffusion-weighted imaging (DWI) tool for measuring inflammation of the sacroiliac joints (SIJs) in enthesitis-related arthritis (ERA).

Methods: A retrospective study was performed with institutional review board approval. Subjects were adolescents who had undergone MRI of the SIJs since January 2010.

Reno Orthopaedic Trauma Fellowship business curriculum.

The Reno Orthopaedic Center (ROC) Trauma Fellowship business curriculum is designed to provide the fellow with a graduate level business practicum and research experience. The time commitments in a typical 12-month trauma fellowship are significant, rendering a traditional didactic master's in business administration difficult to complete during this short time. An organized, structured, practical business education can provide the trauma leaders of tomorrow with the knowledge and experience required to effectively navigate the convoluted and constantly changing healthcare system.

Operating room efficiency: benefits of an orthopaedic traumatologist at a level II trauma center.

Why veteran orthopaedic trauma surgeons are being fired and what we can do about it?

The financial realities of providing trauma care to injured patients can make it difficult to produce an accurate assessment of the cumulative value orthopaedic trauma surgeons provide to healthcare and university institutions. As with many political battles in the field of medicine, physicians who have been diligently focused on providing patient care were completely unaware of the impending upheaval around them. Whether orthopaedic trauma surgeons are employed or in some type of partnership with hospitals, too often surgeons find the relationship one-sided.

Orthopaedist-hospital alignment in a community setting.

Background: Physician-hospital alignments are becoming more common in today's healthcare environment. In the community setting, these relationships can impact quality of care as well as physician and hospital bottom lines. Alignment strategies take many different forms and can be advantageous to both the community orthopaedist and the community hospital, but certain key factors must be present to prevent a failed effort.

Clinical and financial comparison of operative and nonoperative treatment of displaced clavicle fractures.

Hypothesis: Surgical stabilization of displaced clavicle fractures was once considered to have rare indications. Our purpose was to present the clinical and economic effects of surgical management using data collected from operative and nonoperative patients.

Methods: Our fracture database was queried from January 1, 2005, to January 1, 2010, identifying 204 patients with displaced midclavicular fractures.

How to negotiate with your hospital.

The orthopaedic trauma market place and career track have changed considerably over the last 10 years. There is an increasing demand from community hospitals for orthopaedic trauma. Understanding how to assess the practice opportunity and engage prospective employers is key to developing a successful and sustainable program and career.
