The objective of the project was to describe an efficient workflow for quantifying and disseminating tumor imaging metrics essential for assessing tumor response in clinical therapeutic trials. The clinical research utility of integration of the workflow into the electronic health record for radiology reporting was measured before and after the intervention.

A search of institutional clinical trial databases was performed to identify trials with radiology department collaborators. Investigator initiated trials, or those which lacked a standardized or automated system of collaboration with the research team were selected for the study. A web based application integrated in the electronic health record platform, the Quantitative Imaging Analysis Core (QIAC) initiative was established as a divisional resource with institutional support to provide standardized and reproducible imaging metrics across the institution. The turnaround time for radiology reports before (phase 1) and after web based application worts.
To evaluate the effect of reduction in effective dose on the reproduction of anatomical structures in chest tomosynthesis (CTS).

Twenty-four CTS examinations acquired at exposure settings resulting in an effective dose of 0.12 mSv for an average sized patient were included in the study. The examinations underwent simulated dose reduction to dose levels corresponding to 32%, 50%, and 70% of the original dose using a previously described and validated method. The image quality was evaluated by five thoracic radiologists who rated the fulfillment of specified image quality criteria in a visual grading study. The ratings for each image quality criterion in the dose-reduced images were compared to the corresponding ratings for the full-dose examinations using visual grading characteristics (VGC) analysis. The area under the resulting VGC curve (AUC
) provides a measure of the difference between the ratings, where an AUC
of 0.5 indicates no difference.

The dose reductions resulted in inferior reproduction of structures compared to the original dose level (AUC
<0.5). Structures in the central region of the lung obtained the lowest AUC
for each dose level whereas the reproduction of structures in the parenchyma was least affected by the dose reduction.

Although previous studies have shown that dose reduction in CTS is possible without affecting the performance of certain clinical tasks, the reproduction of normal anatomical structures is significantly degraded even at small reductions. It is therefore important to consider the clinical purpose of the CTS examinations before deciding on a permanent dose reduction.

The aim of our study was to preoperatively predict the human epidermal growth factor receptor 2 (HER2) status of patients with breast cancer using radiomics signatures based on single-parametric and multiparametric magnetic resonance imaging (MRI).

Three hundred six patients with invasive ductal carcinoma of no special type (IDC-NST) were retrospectively enrolled. Quantitative imaging features were extracted from fat-suppressed T2-weighted and dynamic contrast-enhanced T1 weighted (DCE-T1) preoperative MRI. Then, three radiomics signatures based on fat-suppressed T2-weighted images, DCE-T1 images and their combination were developed using a support vector machine (SVM) to predict the HER2-positive vs HER2-negative status of patients with breast cancer. The area under the curve (AUC), accuracy, sensitivity, and specificity were calculated to assess the predictive performances of the signatures.

Twenty-eight quantitative radiomics features, namely, 14 texture features, 4 first-order features, 9 wavelet features, and 1 shape feature, were used to construct radiomics signatures. The performance of the radiomics signatures for distinguishing HER2-positive from HER2-negative breast cancer based on fat-suppressed T2-weighted images, DCE-T1 images, and their combination had an AUC of 0.74 (95% confidence interval [CI], 0.700 to 0.770), 0.71 (0.673 to 0.738), and 0.86 (0.832 to 0.882) in the primary cohort and 0.70 (0.666 to 0.744), 0.68 (0.650 to 0.726), and 0.81 (0.776 to 0.837) in the validation cohort, respectively.

Radiomics signatures based on multiparametric MRI represent a potential and efficient alternative tool to evaluate the HER2 status in patients with breast cancer.

Transversus abdominis plane (TAP) block is a form of regional anesthesia that has been increasingly employed in minimally invasive surgery. The data regarding its use in laparoscopic bariatric surgery, however, are still limited and at times controversial.

The aim of this meta-analysis was to assess the efficacy of TAP block after laparoscopic bariatric surgery.

Soba University Hospital, Sudan.

A systematic search was conducted through the Embase, Cochrane Collaboration, and PubMed databases for randomized controlled trials evaluating the effects of TAP block in patients undergoing laparoscopic bariatric surgery. Meta-analysis was performed using a random effects model. Primary endpoints were late (24 hr) pain scores at rest and on movement. Pyroxamide cell line Secondary endpoints included early (0-3 hr) pain scores at rest and on movement, opioid consumption, time to ambulation, length of hospital stay, and adverse events.

Ten randomized controlled trials met our inclusion criteria, with 404 patients in the TAP block -acting anesthetic should be encouraged in routine practice in patients undergoing laparoscopic bariatric surgery.
Given the significant effect on early and late postoperative pain, opioid consumption, and postoperative recovery and the low risk profile, TAP block using a short-acting anesthetic should be encouraged in routine practice in patients undergoing laparoscopic bariatric surgery.
