OBJECTIVE - To assess drug reactions (ADRs) encountered by practicing urologists for contrast instilled into the urinary collecting system, and to describe current practice patterns regarding contrast administration into the urinary tract for patients with known contrast allergies.
METHODS - Endourological Society members were e-mailed a web-based survey about their prior experience with contrast-related ADRs and practices for contrast administration into the urinary tract among patients with known intravenous contrast allergies. Chi-squared analysis was used to compare management patterns between patients with established allergies and those without.
RESULTS - An estimated 2300-2500 e-mails were reached, resulting in an estimated response rate of 6.3%-8%. Over 75% of respondents were fellowship trained. Average time in practice was 16 years, and respondents performed a mean of 6.7 urologic contrast studies per week. Among respondents, 32.6%, 14.7%, and 4.0% had treated at least 1 patient with a mild, moderate, or severe reaction, respectively. Contrast-related ADRs were most commonly associated with retrograde pyelogram (50%). For patients with known contrast allergies, 5.4% pursue additional work-up before administering contrast in the urinary tract. Pretreatment with antihistamine or steroids is used by 24.8% and 23.4%, respectively. When performing retrograde pyelograms for such patients, urologists are more likely to use dilute contrast (P = .003), but otherwise do not significantly alter technique.
CONCLUSION - Contrast ADRs are encountered not infrequently among practicing urologists. There is notable practice variation in the management of patients with known contrast allergies, though the overall perceived risk of contrast use in these patients is low, provided good technique is used.

Use of the thyroid imaging, reporting, and data system (TI-RADS) scoring system for the evaluation of subcentimeter thyroid nodules.
Weiss VL, Andreotti RF, Ely KA
(2018) Cancer Cytopathol 126: 518-524
MeSH Terms: Adult, Aged, Aged, 80 and over, Biopsy, Fine-Needle, Data Systems, Female, Follow-Up Studies, Humans, Image Processing, Computer-Assisted, Male, Middle Aged, Practice Guidelines as Topic, Prognosis, Retrospective Studies, Societies, Medical, Thyroid Gland, Thyroid Neoplasms, Thyroid Nodule, Ultrasonography, Young Adult
Show Abstract · Added April 15, 2019
BACKGROUND - The American Thyroid Association (ATA) recommends fine-needle aspiration (FNA) biopsy of nodules measuring >1.5 cm with low-suspicion sonographic patterns or >1.0 cm with high/intermediate-suspicion features. Routine biopsy of nodules <1 cm is not recommended. However, despite these recommendations, subcentimeter nodules are often referred for FNA biopsy.
METHODS - This was a retrospective chart review of consecutive thyroid FNAs during an 18-month period (1157 patients, 1491 nodules, 2016-2017) to evaluate age, sex, medical history, diagnoses, and follow-up. Radiographic information was used to identify 61 subcentimeter nodules (4%) from 57 patients. Ultrasound studies were re-evaluated using criteria according to the American College of Radiology Thyroid Imaging, Reporting, and Data System (TI-RADS).
RESULTS - Reported reasons for biopsy included a larger companion nodule (44%), a personal or family history of cancer (26%), or a suspicious sonogram, including calcification and/or irregular contours (16%). FNA diagnoses included: 69% benign (42 of 61 nodules), 10% papillary thyroid carcinoma (PTC) (6 of 61 nodules), and 15% atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) (9 of 61 nodules). Seven percent of nodules were unsatisfactory/nondiagnostic (4 of 61 nodules) compared with a 3% nondiagnostic rate for all sized nodules. Fifty-one nodules had an ultrasound available for re-review using the TI-RADS scoring system. A high TI-RADS score (4-5) was indicative of PTC in 29.4% of nodules. A low TI-RADS score (1-2) was indicative of PTC in 0% of nodules (P < .01). High and intermediate TI-RADS scores (3 and 4-5, respectively) were indicative of PTC/AUS/FLUS in 32% of nodules compared with 0% in those with low TI-RADS scores (P < .01).
CONCLUSIONS - The current results demonstrate successful use of the TI-RADS scoring system in evaluation of the risk of malignancy in subcentimeter nodules. Larger studies will be necessary to determine whether biopsy is warranted for TI-RADS high-subcentimeter nodules. Cancer Cytopathol 2018. © 2018 American Cancer Society.

Mazzone PJ, Sears CR, Arenberg DA, Gaga M, Gould MK, Massion PP, Nair VS, Powell CA, Silvestri GA, Vachani A, Wiener RS, ATS Assembly on Thoracic Oncology
(2017) Am J Respir Crit Care Med 196: e15-e29
MeSH Terms: Biomarkers, Tumor, Early Detection of Cancer, Humans, Lung Neoplasms, Societies, Medical, United States
Show Abstract · Added January 29, 2018
BACKGROUND - Molecular biomarkers have the potential to improve the current state of early lung cancer detection. The goal of this project was to develop a policy statement that provides guidance about the level of evidence required to determine that a molecular biomarker, used to support early lung cancer detection, is appropriate for clinical use.
METHODS - An ad hoc project steering committee was formed, to include individuals with expertise in the early detection of lung cancer and molecular biomarker development, from inside and outside of the Assembly on Thoracic Oncology. Key questions, generated from the results of a survey of the project steering committee, were discussed at an in-person meeting. Results of the discussion were summarized in a policy statement that was circulated to the steering committee and revised multiple times to achieve consensus.
RESULTS - With a focus on the clinical applications of lung cancer screening and lung nodule evaluation, the policy statement outlines categories of results that should be reported in the early phases of molecular biomarker development, discusses the level of evidence that would support study of the clinical utility, describes the outcomes that should be proven to consider a molecular biomarker clinically useful, and suggests study designs capable of assessing these outcomes.
CONCLUSIONS - The application of molecular biomarkers to assist with the early detection of lung cancer has the potential to substantially improve our ability to select patients for lung cancer screening, and to assist with the characterization of indeterminate lung nodules. We have described relevant considerations and have suggested standards to apply when determining whether a molecular biomarker for the early detection of lung cancer is ready for clinical use.

Show Abstract · Added April 3, 2017
Interventional pulmonology (IP) is a rapidly evolving subspecialty of pulmonary medicine. In the last 10 years, formal IP fellowships have increased substantially in number from five to now > 30. The vast majority of IP fellowship trainees are selected through the National Resident Matching Program, and validated in-service and certification examinations for IP exist. Practice standards and training guidelines for IP fellowship programs have been published; however, considerable variability in the environment, curriculum, and experience offered by the various fellowship programs remains, and there is currently no formal accreditation process in place to standardize IP fellowship training. Recognizing the need for more uniform training across the various fellowship programs, a multisociety accreditation committee was formed with the intent to establish common accreditation standards for all IP fellowship programs in the United States. This article provides a summary of those standards and can serve as an accreditation template for training programs and their offices of graduate medical education as they move through the accreditation process.

Show Abstract · Added March 14, 2018
CONTEXT - - ERBB2 (erb-b2 receptor tyrosine kinase 2 or HER2) is currently the only biomarker established for selection of a specific therapy for patients with advanced gastroesophageal adenocarcinoma (GEA). However, there are no comprehensive guidelines for the assessment of HER2 in patients with GEA.
OBJECTIVES - - To establish an evidence-based guideline for HER2 testing in patients with GEA, to formalize the algorithms for methods to improve the accuracy of HER2 testing while addressing which patients and tumor specimens are appropriate, and to provide guidance on clinical decision making.
DESIGN - - The College of American Pathologists, American Society for Clinical Pathology, and American Society of Clinical Oncology convened an expert panel to conduct a systematic review of the literature to develop an evidence-based guideline with recommendations for optimal HER2 testing in patients with GEA.
RESULTS - - The panel is proposing 11 recommendations with strong agreement from the open-comment participants.
RECOMMENDATIONS - - The panel recommends that tumor specimen(s) from all patients with advanced GEA, who are candidates for HER2-targeted therapy, should be assessed for HER2 status before the initiation of HER2-targeted therapy. Clinicians should offer combination chemotherapy and a HER2-targeted agent as initial therapy for all patients with HER2-positive advanced GEA. For pathologists, guidance is provided for morphologic selection of neoplastic tissue, testing algorithms, scoring methods, interpretation and reporting of results, and laboratory quality assurance.
CONCLUSIONS - - This guideline provides specific recommendations for assessment of HER2 in patients with advanced GEA while addressing pertinent technical issues and clinical implications of the results.

Show Abstract · Added March 26, 2017
There is an increasing awareness and clinical interest in cardiac safety during cancer therapy as well as in optimally addressing cardiac issues in cancer survivors. Although there is an emerging expertise in this area, known as cardio-oncology, there is a lack of organization in the essential components of contemporary training. This proposal, an international consensus statement organized by the International Cardioncology Society and the Canadian Cardiac Oncology Network, attempts to marshal the important ongoing efforts for training the next generation of cardio-oncologists. The necessary elements are outlined, including the expectations for exposure necessary to develop adequate training. There should also be a commitment to local, regional, and international education and research in cardio-oncology as a requirement for advancement in the field.

(2016) Epilepsy Res 122: 26-9
MeSH Terms: Adult, Databases, Factual, Electrocorticography, Female, General Surgery, Humans, Male, Postoperative Complications, Quality Improvement, Societies, Medical, United States
Show Abstract · Added August 12, 2016
The risk profile of extraoperative electrocorticography (ECoG) is documented almost exclusively by case series from a limited number of academic medical centers. These studies tend to underreport minor complications, like urinary tract infections (UTIs) and deep venous thromboses (DVTs), that nevertheless affect hospital cost, length of stay, and the patient's quality of life. Herein, we used data from the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) to estimate the rate of adverse events in extraoperative ECoG surgeries. NSQIP is a validated dataset containing nearly 3 million procedures from over 600 North American hospitals, and uses strict criteria for the documentation of complications. Major complications occurred in 3.4% of 177 extraoperative ECoG cases, while minor complications occurred in 9.6%. The most common minor complication was bleeding requiring a transfusion in 3.4% of cases, followed by sepsis, DVT, and UTI each in 2.3% of cases. No mortality was reported. Overall, in a national database containing a heterogeneous population of hospitals, major complications of extraoperative ECoG were rare (3.4%). Complications such as UTI and DVT tend to be underreported in retrospective case series, yet make up a majority of minor complications for ECoG patients in this dataset.

Show Abstract · Added March 14, 2018
The American Medical Informatics Association convened the 2014 Health Policy Invitational Meeting to develop recommendations for updates to current policies and to establish an informatics research agenda for personalizing medicine. In particular, the meeting focused on discussing informatics challenges related to personalizing care through the integration of genomic or other high-volume biomolecular data with data from clinical systems to make health care more efficient and effective. This report summarizes the findings (n = 6) and recommendations (n = 15) from the policy meeting, which were clustered into 3 broad areas: (1) policies governing data access for research and personalization of care; (2) policy and research needs for evolving data interpretation and knowledge representation; and (3) policy and research needs to ensure data integrity and preservation. The meeting outcome underscored the need to address a number of important policy and technical considerations in order to realize the potential of personalized or precision medicine in actual clinical contexts.
