#1
Liena Zhao, Dora Dias-Santagata, Peter M Sadow, William C Faquin
BACKGROUND: The noninvasive follicular variant of papillary thyroid carcinoma (PTC) has an indolent clinical behavior in comparison with other PTCs, including the invasive follicular variant of papillary thyroid carcinoma (IFVPTC). Recently, the term noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) was introduced to emphasize the low biological potential of these tumors. This study compares clinical, cytological, and molecular features of NIFTP and IFVPTC...

David J Kim, Shiqian Shen, George M Hanna
BACKGROUND: Total hip arthroplasty (THA) is a common surgical treatment for several conditions of the hip. While the majority of patients obtain satisfactory results, many develop chronic post-arthroplasty hip pain that can be difficult to treat. OBJECTIVE: We evaluate the effectiveness of cooled (60°C) radiofrequency lesioning of the articular branches of the femoral nerve (ABFN) as a minimally invasive treatment for patients suffering from chronic post-arthroplasty hip pain...

Alex Blair, Farrin A Manian
BACKGROUND: Although the causes of falls are legion, infectious disease-related factors are not commonly reported in the published literature. We investigated the characteristics of patients presenting to the hospital because of a fall and who were subsequently found to have a coexisting systemic infection (CSI). MATERIALS AND METHODS: This was a retrospective study performed at Massachusetts General Hospital, using the electronic database of adult patients receiving care during the period January 1, 2000 through December 31, 2014...

C Williams, E Crowley, J Wolfgang
PURPOSE: Intraoperative electron radiotherapy (IORT) poses a unique set of challenges for treatment planning. Planning must be performed in a busy operating room environment over a short timeframe often with little advance knowledge of the treatment depth or applicator size. Furthermore, IORT accelerators can have a large number of possible applicators, requiring extensive databooks that must be searched for the appropriate dosimetric parameters. The goal of this work is to develop a software tool to assist in the planning process that is suited to the challenges faced in the IORT environment...

Thomas H McCoy, Victor M Castro, Ashlee M Roberson, Leslie A Snapper, Roy H Perlis
Importance: Suicide represents the 10th leading cause of death across age groups in the United States (12.6 cases per 100 000) and remains challenging to predict. While many individuals who die by suicide are seen by physicians before their attempt, they may not seek psychiatric care. Objective: To determine the extent to which incorporating natural language processing of narrative discharge notes improves stratification of risk for death by suicide after medical or surgical hospital discharge...

UNLABELLED: : The last decade in oncology has witnessed impressive response rates with targeted therapies, largely because of collaborative efforts at understanding tumor biology and careful patient selection based on molecular fingerprinting of the tumor. Consequently, there has been a push toward routine molecular genotyping of tumors, and large precision medicine-based clinical trials have been launched to match therapy to the molecular alteration seen in a tumor. However, selecting the "right drug" for an individual patient in clinic is a complex decision-making process, including analytical interpretation of the report, consideration of the importance of the molecular alteration in driving growth of the tumor, tumor heterogeneity, the availability of a matched targeted therapy, efficacy and toxicity considerations of the targeted therapy (compared with standard therapy), and reimbursement issues...

CONTEXT: Cystic prolactinomas are considered resistant to volume reduction by dopamine agonists (DAs). Although several individual case reports and small case series have suggested that DAs may reduce these lesions, larger series using standardized imaging metrics are lacking. OBJECTIVE: The objectives of the study were to assess the efficacy of DAs on cyst size in patients with predominantly cystic prolactinomas and to characterize the clinical course and treatment outcomes in these patients...

PURPOSE: The implementation of a required residency rotation in transitions of care (TOCs) and the resulting resident-led clinical interventions and learning experiences are described. SUMMARY: A newly required four-week TOC rotation was implemented for postgraduate year 1 (PGY1) pharmacy residents at Massachusetts General Hospital (MGH). Unlike acute care rotations, this learning experience encouraged residents to focus on providing direct patient care in a holistic manner and use pharmacologic and nonpharmacologic strategies to improve patient outcomes...

BACKGROUND: Milestones evaluations in plastic surgery reflect a shift toward competency-based training but have created a number of challenges. The authors have incorporated the smartphone application evaluation tool, System for Improving and Measuring Procedural Learning (SIMPL), that was recently developed by a multi-institutional research collaborative. In this pilot study, the authors hypothesize that SIMPL can improve resident evaluation and also collect granular performance data to simplify compliance with the plastic surgery Milestones...

Purpose To determine the impact of nonvascular thoracic magnetic resonance (MR) imaging on the clinical decision making and diagnostic certainty of thoracic surgeons. Materials and Methods Seven thoracic surgeons at Massachusetts General Hospital, an academic quaternary referral hospital, participated in this 2-year, prospective, institution review board-approved, HIPAA-compliant pre- and post-MR imaging survey study after completing a one-time demographic survey. Between July 16, 2013, and July 13, 2015, each time a thoracic surgeon ordered a nonvascular thoracic MR imaging study via radiology order entry, he or she was sent a link to the pre-test survey that ascertained the clinical rationale for MR imaging, the clinical management plan if MR imaging was not an option, and pre-test diagnostic certainty...

BACKGROUND: Understanding the sources of variation for high-cost services has the potential to improve both patient outcomes and value in health care delivery. Nationally, the overall diagnostic yield of coronary angiography is relatively low, suggesting overutilization. Understanding how individual cardiologists request catheterization may suggest opportunities for improving quality and value. We aimed to assess and explain variation in positive angiograms among referring cardiologists...

BACKGROUND: Recurrent dissection of a previously dissected aortic segment has been reported as a rare, late complication in single case reports. The infrequency of this event makes informed risk assessment in an individual patient challenging. METHODS: To investigate this issue we examined the database of the Massachusetts General Hospital Thoracic Aortic Center between January 1, 2003 and December 31, 2012. A retrospective review was performed to identify patients with both (1) an acute aortic dissection after a prior aortic dissection and (2) evidence of a new dissection within a previously dissected aortic segment creating a triple lumen aorta...

BACKGROUND: Prior reports indicate a wide range of melanomas in histopathologic contiguity with a nevus, and an associated nevus has unclear prognostic implications in melanoma. OBJECTIVE: We sought to investigate the relationship among nevus-associated melanomas, sentinel lymph node status, and overall survival. METHODS: We conducted a retrospective analysis of 850 patients with cutaneous melanoma and sentinel lymph node removed at Massachusetts General Hospital from 1998 through 2008 and meta-analysis of the literature...

BACKGROUND: The postprocedural state after cardiac revascularization interventions is characterized by intense inflammation and activation of inflammatory cytokines due to myonecrosis and ischemia/reperfusion injury. Involvement of similar processes also participates in cellular malignant transformation. In this study, the association between cardiac interventions and subsequent cancer risk development was therefore evaluated. METHODS: The 5-year cumulative incidence of cancer was examined in 2 cardiac care cohorts: all patients undergoing either open heart surgery or percutaneous coronary interventions (PCI) at hospitals in the commonwealth of Massachusetts...

BACKGROUND: There is an urgent need to improve lung cancer outcome by identifying and validating markers of risk. We previously reported that the cytokinesis-blocked micronucleus assay (CBMN) is a strong predictor of lung cancer risk. Here, we validate our findings in an independent external lung cancer population and test discriminatory power improvement of the Spitz risk prediction model upon extension with this biomarker. METHODS: A total of 1,506 participants were stratified into a test set of 995 (527 cases/468 controls) from MD Anderson Cancer Center (Houston, TX) and a validation set of 511 (239 cases/272 controls) from Massachusetts General Hospital (Boston, MA)...
