A Common Drug With a Dangerous Side Effect: Acute Rhabdomyolysis Caused by the Synergistic Effect of Isotretinoin and Exercise in an Adolescent.

Isotretinoin or 13-cis-retinoic acid, a derivative of vitamin A, is a highly effective therapy for severe and resistant acne. Its usage is restricted worldwide because of its teratogenic potential. The most common side effects are dermatologic, cheilitis, increased skin fragility, and susceptibility to sunburns.

A first-in-human phase 1 and pharmacological study of TAS-119, a novel selective Aurora A kinase inhibitor in patients with advanced solid tumours.

Background: This is a first-in-human study with TAS-119, an Aurora A kinase (AurA) inhibitor.

Methods: Patients with advanced, refractory, solid tumours were enrolled into 5 dose escalation cohorts (70-300 mg BID, 4 days on/3 days off, 3 out of 4 weeks or 4 out of 4 weeks). The expansion part consisted of patients with small-cell lung cancer, HER2-negative breast cancer, MYC-amplified/β-catenin-mutated (MT) tumours or other (basket cohort).

Automated Quality Assurance of OAR Contouring for Lung Cancer Based on Segmentation With Deep Active Learning.

Ensuring high-quality data for clinical trials in radiotherapy requires the generation of contours that comply with protocol definitions. The current workflow includes a manual review of the submitted contours, which is time-consuming and subjective. In this study, we developed an automated quality assurance (QA) system for lung cancer based on a segmentation model trained with deep active learning.

Background & Aims: The direct-acting antiviral combination glecaprevir/pibrentasvir has been approved by the Food and Drug Administration for 8 weeks of treatment in treatment-naïve patients with hepatitis C virus (HCV) infection without cirrhosis or with compensated cirrhosis. We performed an integrated analysis of data from trials to evaluate the overall efficacy and safety of 8 weeks of glecaprevir/pibrentasvir in treatment-naïve patients without cirrhosis or with compensated cirrhosis.

Methods: We pooled data from 8 phase 2 or phase 3 trials of treatment-naïve patients with HCV genotype 1 to 6 infections, without cirrhosis or with compensated cirrhosis, who received 8 weeks of glecaprevir/pibrentasvir.

Expansion of the dimensions in the current management of acute ischemic stroke.

Stroke is the fifth leading cause of death in the United States with a huge burden on health care. Acute ischemic stroke (AIS) accounts for 87% of all stroke. The use of thrombolytic agents in AIS treatment is well known since 1950 but no FDA approval until 1996, due to lack of strong evidence showing benefits outweigh the risk of intracranial hemorrhage.

Outcomes After Left Main Coronary Artery Revascularization by Percutaneous Coronary Intervention or Coronary Artery Bypass Grafting According to Smoking Status.

Cigarette smoking is a well-known risk factor for coronary artery disease (CAD). However, the impact of smoking on outcomes after coronary revascularization, especially in patients with left main CAD (LMCAD) is less well understood. The EXCEL trial randomized 1,905 patients with LMCAD and visually assessed low or intermediate anatomical complexity (SYNTAX score ≤32) to PCI with everolimus-eluting stents or CABG.

The impact of the effective dose to immune cells on lymphopenia and survival of esophageal cancer after chemoradiotherapy.

Purpose: To test the hypothesis that effective dose to circulating immune cells (EDIC) impacts the severity of radiation-induced lymphopenia and clinical outcomes of esophageal cancer patients treated with concurrent chemoradiotherapy (CCRT).

Material And Methods: 488 esophageal cancer patients treated with CCRT with and without surgery were analyzed. The EDIC model considers the exposure of circulating immune cells as the proportion of blood flow to lung, heart, liver, and the volume of the exposed area of the body, with the basis of mean lung dose (MLD), mean heart dose (MHD), mean liver dose (MlD), and integral dose (ITD) of the body region scanned, calculated as: EDIC=0.

Impact of left ventricular ejection fraction on clinical outcomes after left main coronary artery revascularization: results from the randomized EXCEL trial.

Aim: To evaluate the impact of left ventricular ejection fraction (LVEF) on 3-year outcomes in patients with left main coronary artery disease (LMCAD) undergoing percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in the EXCEL trial.

Methods And Results: The EXCEL trial randomized patients with LMCAD to PCI with everolimus-eluting stents (n = 948) or CABG (n = 957). Among 1804 patients with known baseline LVEF, 74 (4.

Epidemiology and outcomes of clinically unsuspected venous thromboembolism in children: A systematic review.

Background: Clinically unsuspected venous thromboembolic events (uVTE) detected during routine imaging pose a management challenge due to limited knowledge about their clinical significance. Unsuspected VTE are often referred as "asymptomatic," "incidental," or "clinically silent/occult" VTE.

Objective: To understand the epidemiology, management, and outcomes of uVTE in children.

Mortality After Repeat Revascularization Following PCI or CABG for Left Main Disease: The EXCEL Trial.

Objectives: The aim of this study was to investigate the incidence and impact on mortality of repeat revascularization after index percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) for left main coronary artery disease (LMCAD).

Background: The impact on mortality of the need of repeat revascularization following PCI or CABG in patients with unprotected LMCAD is unknown.

Methods: All patients with LMCAD and site-assessed low or intermediate SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) scores randomized to PCI (n = 948) or CABG (n = 957) in the EXCEL (Evaluation of XIENCE Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial were included.

Cancer genome landscape: a radiologist's guide to cancer genome medicine with imaging correlates.

The introduction of high throughput sequence analysis in the past decade and the decrease in sequencing costs has made available an enormous amount of genomic data. These data have shaped the landscape of cancer genome, which encompasses mutations determining tumorigenesis, the signaling pathways involved in cancer growth, the tumor heterogeneity, and its role in development of metastases. Tumors develop acquiring a series of driver mutations over time.

Stable, three degree-of-freedom myoelectric prosthetic control via chronic bipolar intramuscular electrodes: a case study.

Background: Modern prosthetic hands are typically controlled using skin surface electromyographic signals (EMG) from remaining muscles in the residual limb. However, surface electrode performance is limited by changes in skin impedance over time, day-to-day variations in electrode placement, and relative motion between the electrodes and underlying muscles during movement: these limitations require frequent retraining of controllers. In the presented study, we used chronically implanted intramuscular electrodes to minimize these effects and thus create a more robust prosthetic controller.

Usefulness of Discharge Resting Heart Rate to Predict Adverse Cardiovascular Outcomes in Patients With Left Main Coronary Artery Disease Revascularized With Percutaneous Coronary Intervention vs Coronary Artery Bypass Grafting (from the EXCEL Trial).

The prognostic impact of resting heart rate (RHR) following revascularization with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in patients with left main coronary artery disease (LMCAD) is unknown. We aimed to assess the effect of RHR at discharge on 3-year cardiovascular outcomes following PCI and CABG for LMCAD. In the EXCEL trial, 1,905 patients with LMCAD were randomized to PCI with everolimus-eluting stents versus CABG.

Stereotactic body radiotherapy in patients with multiple lung tumors: a focus on lung dosimetric constraints.

: Lung dosimetric constraints with stereotactic body/ablative radiotherapy (SBRT/SABR) for multiple lung lesions are not well-characterized in published literature. Classically, the lung is considered a 'parallel' organ, for which injury to functional subunits could result in partially compromised function of that organ/tissue. Therefore, with SBRT/SABR for >1 thoracic target (especially involving both lungs), lung dosimetry requires special consideration.

Hypoxia, hypercarbia, and mortality reporting in studies of anaesthesia-related neonatal neurodevelopmental delay in rodent models: A systematic review.

Background: The concept of anaesthesia-related neonatal neurotoxicity originated in neonatal rodent models, yet prospective clinical studies have largely not supported this concern.

Objectives: To determine the frequency and magnitude of hypercarbia, hypoxia and death in rodent models of neonatal anaesthetic toxicity and neurodevelopmental delay.

Design: Systematic review of published rodent studies of neonatal anaesthesia neurotoxicity.

Impact of non-respect of SYNTAX score II recommendation for surgery in patients with left main coronary artery disease treated by percutaneous coronary intervention: an EXCEL substudy.

Objectives: The SYNTAX score II (SSII) was developed from the SYNTAX trial to predict the 4-year all-cause mortality after left main or multivessel disease revascularization and to facilitate the decision-making process. The SSII provides the following treatment recommendations: (i) coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) (equipoise risk), (ii) CABG preferred (excessive risk for PCI) or (iii) PCI preferred (excessive risk for CABG). We sought to externally validate SSII and to investigate the impact of not abiding by the SSII recommendations in the randomized EXCEL trial of PCI versus CABG for left main disease.

Initial skin cancer screening for solid organ transplant recipients in the United States: Delphi method development of expert consensus guidelines.

Skin cancer is the most common malignancy affecting solid organ transplant recipients (SOTR), and SOTR experience increased skin cancer-associated morbidity and mortality. There are no formal multidisciplinary guidelines for skin cancer screening after transplant, and current practices are widely variable. We conducted three rounds of Delphi method surveys with a panel of 84 U.

Left Main Coronary Artery Disease Revascularization According to the SYNTAX Score.

Background: The SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) score (SS), a measure of anatomic coronary artery disease (CAD) extent and complexity, has proven useful in past studies to determine the absolute and relative prognosis after revascularization with percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG). We sought to assess contemporary outcomes after PCI and CABG in patients with left main CAD according to SS and revascularization type from a large randomized trial.

Methods: The EXCEL trial (Evaluation of XIENCE Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) randomized patients with left main CAD and site-assessed SS≤32 to PCI with everolimus-eluting stents or CABG.
