The aim of this study was to evaluate the effect of a deep learning based computer-aided diagnosis (DL-CAD) system on radiologists' interpretation accuracy and efficiency in reading biparametric prostate magnetic resonance imaging scans.

We selected 100 consecutive prostate magnetic resonance imaging cases from a publicly available data set (PROSTATEx Challenge) with and without histopathologically confirmed prostate cancer. Seven board-certified radiologists were tasked to read each case twice in 2 reading blocks (with and without the assistance of a DL-CAD), with a separation between the 2 reading sessions of at least 2 weeks. Reading tasks were to localize and classify lesions according to Prostate Imaging Reporting and Data System (PI-RADS) v2.0 and to assign a radiologist's level of suspicion score (scale from 1-5 in 0.5 increments; 1, benign; 5, malignant). Ground truth was established by consensus readings of 3 experienced radiologists. The detection performance (receiver operating characteristic cing time.

Macrophages accumulating in the periablational rim play a pivotal role in initiating and sustaining the perifocal inflammatory reaction, which has been shown to be at least 1 of the mechanisms responsible for the systemic pro-oncogenic effects of focal hepatic radiofrequency ablation (RFA). Herein, we tested the hypothesis to use superparamagnetic iron oxide nanoparticle (SPION)-enhanced magnetic resonance imaging (MRI) for noninvasive quantification of iron-loaded macrophages in the periablational rim of VX2 tumor-bearing rabbits.

Twelve VX2 tumor-bearing rabbits underwent MRI immediately after and up to 3 weeks after focal hepatic RFA. For noninvasive quantification of macrophage accumulation in the periablational rim, animals were scanned before and 24 hours after SPION injection. T2*-weighted images were analyzed and correlated with histopathological and immunohistochemical findings. Furthermore, correlations with quantitative measurements (ICP-MS [inductively coupled plasma-mass spectrometry] and LA-noninvasive monitoring and quantification of ablation-induced macrophage recruitment in the periablational rim. Given the close interplay between ablation-induced perifocal inflammation and potential unwanted tumorigenic effects of RFA, SPION-enhanced MRI may serve as a valuable tool to guide and modulate adjuvant therapies after hepatic RFA.

Rhabdomyolysis (RM) is a complex set of clinical syndromes that involves the rapid dissolution of skeletal muscles. Mortality from rhabdomyolysis is approximately 10%. This study aimed to develop an interpretable and generalizable model for early mortality prediction in RM patients.

Retrospective analyses were performed on two electronic medical record databases the eICU Collaborative Research Database (eICU-CRD) and the Medical Information Mart for Intensive Care III (MIMIC- III) database. We extracted data from the first 24h after patient ICU admission. Data from the two datasets were merged for further analysis. The merged datasets were randomly divided, with 70% used for training and 30% for validation. We used the machine learning model XGBoost (extreme gradient boosting (XGBoost) with the Shapley additive explanation method to conduct early and interpretable predictions of patient mortality. Five typical evaluation indexes were adopted to develop a generalizable model.

In total, 938 patients with ICU.

The aims of this study were [1] to model the temporal profile of W' recovery following exhaustion, [2] to estimate the contribution of changing V˙O2 kinetics to this recovery, and [3] to examine associations with aerobic fitness and muscle fiber type (MFT) distribution.

21 men (age=25±2 yr, V˙O2peak=54.4±5.3 mL·min-1·kg-1) performed several constant load tests to determine CP and W' and eight trials to quantify W' recovery. Each test consisted of two identical exhaustive work bouts (WB1 and WB2), separated by a variable recovery interval of 30, 60, 120, 180, 240, 300, 600, or 900 s. Gas exchange was measured and muscle biopsies were collected to determine MFT distribution. W' recovery was quantified as [1] observed W' recovery (W'OBS), model-predicted W' recovery (W'BAL), and W' recovery corrected for changing V˙O2 kinetics (W'ADJ). W'OBS and W'ADJ were modelled using mono- and biexponential fitting. Root mean square error (RMSE) and Akaike Information Criterion ([INCREMENT]AICC) were used to evaluate theaerobic energy provision resulting from changes in the V˙O2 kinetics.

To conduct a systematic review and meta-analysis of active rehabilitation on concussion management. We also examined moderator variables that may contribute to differences across studies symptom scale, physical activity type, time of injury to recruitment, and mechanism of injury.

The standardized effect size of physical activity on concussion management was computed for 23 studies (29 effect sizes). Effect sizes were coded as positive when studies reported an improvement in symptom scores, which was represented by a decrease in post-concussive symptom scores.

The overall effect size of physical activity in concussion recovery was large and positive (g=1.03). Subthreshold aerobic activity provided the largest effect size (g=1.71), while multimodal interventions had a moderate effect size (g=0.70). All other moderator variables produced positive effect sizes ranging from g=0.59-1.46.

This systematic review and meta-analysis demonstrates that current evidence supports the notion that physical activity is beneficial in decreasing PCS in both the acute and chronic phase post-concussion. The results indicate that unimodal subthreshold aerobic activity may be the best course of action compared with multimodal interventions. Despite this growing body of evidence, additional research is needed to determine the optimal intensity, duration, and time to initiation of aerobic exercise following concussion.
