A number of important drugs used to treat cancer-many of which serve as the backbone of modern chemotherapy regimens-have outdated prescribing information in their drug labeling. The Food and Drug Administration is undertaking a pilot project to develop a process and criteria for updating prescribing information for longstanding oncology drugs, based on the breadth of knowledge the cancer community has accumulated with the use of these drugs over time. This article highlights a number of considerations for labeling updates, including selecting priorities for updating; data sources and evidentiary criteria; as well as the risks, challenges, and opportunities for iterative review to ensure prescribing information for oncology drugs remains relevant to current clinical practice.

Background: We aimed to examine whether using a high fraction of inspired oxygen (FIO) in the context of an individualised intra- and postoperative open-lung ventilation approach could decrease surgical site infection (SSI) in patients scheduled for abdominal surgery.

Methods: We performed a multicentre, randomised controlled clinical trial in a network of 21 university hospitals from June 6, 2017 to July 19, 2018. Patients undergoing abdominal surgery were randomly assigned to receive a high (0.

Background: First experiences in the operating theatre with real patients are always stressful and intimidating for students. We hypothesized that a game-like simulation could improve perceptions and performance of novices.

Methods: A videogame was developed, combining pictures and short videos, by which students are interactively instructed on acting at the surgical block.

To retrospectively compare low-dose (7-10 mCi) to high-dose (15-30 mCi) breast-specific gamma imaging (BSGI) in the detection of breast cancer. A retrospective review of 223 consecutive women who underwent BSGI exam between February 2011 and August 2013 with subsequent pathologic analysis was performed. Women were divided into low-dose and high-dose groups.

Purpose: To determine improvement in breast cancer detection by using supplemental three-dimensional (3D) automated breast (AB) ultrasonography (US) with screening mammography versus screening mammography alone in asymptomatic women with dense breasts.

Materials And Methods: Institutional review board approval and written informed consent were obtained for this HIPAA-compliant study. The SomoInsight Study was an observational, multicenter study conducted between 2009 and 2011.

An oxidation product (5) formed during the synthesis of BIBN-4096BS (1) was found to be a potent CGRP antagonist (IC50=0.11nM). While 5 was found to be ten-fold less potent than 1, another analog 8 with lower molecular weight containing the oxidized fragment demonstrated twenty-fold higher activity than its parent 7.

Objective: The purpose of this study was to evaluate the sensitivity of breast-specific gamma imaging (BSGI) for the detection of breast cancer in dense versus nondense breasts.

Materials And Methods: This was a retrospective study of 341 women with biopsy-proven breast cancer diagnosed from January 2004 to August 2009 who underwent BSGI before surgical excision. Patients with predominantly fatty replaced (BI-RADS density 1) or scattered fibroglandular tissue (BI-RADS density 2) breasts were classified as nondense, and those with heterogeneously dense (BI-RADS density 3) or extremely dense tissue (BIRADS density 4) were classified as dense.

Twenty years ago, the Spanish National Transplant Organization (NTO) started a management and organizational system, known as the Spanish Model, that has allowed the NTO to occupy a privileged world position regarding deceased donation rates, which have been 33-35 donors per million population in recent years. One of the key elements of this model is its instructional approach. Two years ago, the NTO started the project "educ@nt" in close collaboration with the e-UCM research group of the University Complutense of Madrid to support and maximize its successful professional training system.

Breast-specific gamma imaging (BSGI) is a physiologic breast imaging modality that provides more sensitive detection of breast lesions than mammography or ultrasound, and appears to have greater specificity than breast MRI. The purpose of this study was to evaluate how often BSGI changed surgical management in patients with breast cancer. Charts were reviewed from 218 consecutive eligible patients who had preoperative evaluation with BSGI or MRI before surgery for breast cancer from January 2008 to May 2010.

Article Synopsis
  • Atypical lesions like atypical ductal hyperplasia (ADH) and lobular neoplasia significantly increase the risk of developing breast cancer and can be detected using breast-specific gamma imaging (BSGI).
  • A study reviewed 1316 BSGI exams and included 15 patients with confirmed ADH or lobular neoplasia, determining the sensitivity of BSGI.
  • Results showed that BSGI had 100% sensitivity in detecting these atypical lesions, indicating its effectiveness in identifying women at increased risk for breast cancer.

Background: A relationship between surgical volume and improved surgical outcomes has been described in gastric bypass patients but the relative importance of surgeon versus hospital volume is unknown. Our objective was to examine whether in-hospital and 30-day mortality are determined more by surgeon volume or hospital volume or whether each has an independent effect. A retrospective cohort study was performed of all hospitals in Pennsylvania providing gastric bypass surgery from 1999 to 2003.

Objective: To assess the effect of tumor size and tumor-to-liver contrast of simulated hypovascular liver tumors on the diagnostic accuracy of hepatic computed tomography (CT).

Materials And Methods: This retrospective study was approved by the institutional review board, and informed consent was waived. A total of 153 simulated hypovascular liver tumors were embedded in 70 hepatic CT data sets that were acquired during the portal venous phase.

Objective: The purpose of this study was to simulate pulmonary emboli (PE) and image quality at low tube energy and reduced contrast material volume in normal-dose pulmonary CT angiography (CTA) images and to analyze the diagnostic accuracy with normal- and low-dose pulmonary CTA.

Materials And Methods: Normal-dose pulmonary CTA examinations using 120 kVp and 100 mL of contrast material in 10 patients with no PE were retrospectively selected. The image characteristics of an 80-kVp low-dose pulmonary CTA protocol (patient exposure reduction, 57%) with 75 mL of contrast material were simulated.

Rationale And Objectives: The aim of this study was to determine how often breast-specific gamma imaging (BSGI) identifies occult cancerous lesions in women with one suspicious lesion detected on mammography or physical exam.

Materials And Methods: A retrospective review was performed of the records of all patients who underwent BSGI between January 1, 2004, and June 4, 2007. Included in the study were 159 women who had one suspicious breast lesion on physical exam and/or mammography and who underwent BSGI to evaluate for occult lesions in the breast.

One of the risks of breast conservation surgery is local recurrence, which predominantly occurs as a result of inadequate surgical margins. The purpose of this study was to identify factors associated with close or positive surgical margins leading to reexcision (RE). The charts of 532 consecutive breast cancer patients treated at our center between September 2001 and June 2007 were reviewed to evaluate patients who opted for breast conservation surgery and needed reexcision.
