(RPE), and 81 out of 314 patients (26%) had mediastinal edema (ME). • Maximal abscess diameter, RPE, and C-reactive protein (CRP) were independent predictors of the need for intensive care unit (ICU) treatment, and maximal abscess diameter, ME, and CRP were independent predictors of length of hospital stay. • Prognostic significance of MRI findings was evident also while controlling for CRP values.
We explored the variations in use of imaging modalities for confirming pulmonary embolism (PE) according to the trimester of pregnancy.

We included all pregnant patients with confirmed acute PE from RIETE, a prospective registry of patients with PE (03/2001-02/2020). Imaging modalities included computed tomography pulmonary angiography (CTPA), ventilation-perfusion (V/Q) scan, or presence of signs of acute PE along with imaging-confirmed proximal deep vein thrombosis (pDVT) without pulmonary vascular imaging. We compared the imaging modalities to postpartum patients with PE, and other non-pregnant women with PE.

There were 157 pregnant patients (age 32.7 ± 0.5), 228 postpartum patients (age 33.9 ± 0.5), and 23,937 non-pregnant non-postpartum women (age 69.5 ± 0.1). CTPA was the most common modality for confirming PE, from 55.7% in first trimester to 58.3% in second trimester, and 70.0% in third trimester. From first trimester to third trimester, V/Q scanning was used in 21.3%, 16.7%, and 18.3% of cases,ased on CTPA. • In the postpartum period, use of CTPA as the modality to confirm pulmonary embolism was comparable to non-pregnant patients.
• Computed tomography pulmonary angiography (CTPA) was the primary modality of diagnosis in all trimesters of pregnancy among patients with confirmed pulmonary embolism, even in the first trimester. • From the first trimester of pregnancy to postpartum period, there was a linear increase in the proportion of patients with pulmonary embolism who were diagnosed based on CTPA. • In the postpartum period, use of CTPA as the modality to confirm pulmonary embolism was comparable to non-pregnant patients.
To evaluate the effects of computer-aided diagnosis (CAD) on inter-reader agreement in Lung Imaging Reporting and Data System (Lung-RADS) categorization.

Two hundred baseline CT scans covering all Lung-RADS categories were randomly selected from the National Lung Cancer Screening Trial. Five radiologists independently reviewed the CT scans and assigned Lung-RADS categories without CAD and with CAD. The CAD system presented up to five of the most risk-dominant nodules with measurements and predicted Lung-RADS category. Inter-reader agreement was analyzed using multirater Fleiss κ statistics.

The five readers reported 139-151 negative screening results without CAD and 126-142 with CAD. With CAD, readers tended to upstage (average, 12.3%) rather than downstage Lung-RADS category (average, 4.4%). Inter-reader agreement of five readers for Lung-RADS categorization was moderate (Fleiss kappa, 0.60 [95% confidence interval, 0.57, 0.63]) without CAD, and slightly improved to substantial (Fleiss kappa, 0.65 [95%sions without and with CAD (54.2% vs. 63.6%). • In 31 cancer-positive cases, substantial management discrepancies between reader pairs, referring to a difference in follow-up interval of at least 9 months (category 1/2 vs. 4A/B), were reduced in half by application of CAD (32/310 to 16/310) (pooled sensitivity, 85.2% vs. 91.6%; p = 0.004).
• Inter-reader agreement of five readers for Lung-RADS categorization was minimally improved by application of CAD, with a Fleiss kappa value of 0.60 to 0.65. • The major cause for disagreement was assignment of different risk-dominant nodules in the reading sessions without and with CAD (54.2% vs. 63.6%). • In 31 cancer-positive cases, substantial management discrepancies between reader pairs, referring to a difference in follow-up interval of at least 9 months (category 1/2 vs. 4A/B), were reduced in half by application of CAD (32/310 to 16/310) (pooled sensitivity, 85.2% vs. 91.6%; p = 0.004).This study aimed to identify the maximum-tolerated dose (MTD) of cyclophosphamide when combined with bortezomib and fludarabine (B-FC) in a phase 1b trial, and to assess the efficacy and safety of this combination in a phase 2 trial in patients with relapsed or refractory MCL (rrMCL). Forty patients were enrolled between April 8, 2011, and October 10, 2015. The MTD of cyclophosphamide was identified to be 250 mg/m2 days 1-2. At a median follow-up of 31.6 months (13.5-47.4), among 32 patients in phase 2, 10 (31%) had a complete response and 13 (41%) had a partial response. The median progression-free survival was 21 months (95% CI 7.3-34.7), and the median overall survival was 32.4 months (95% CI 17.8-47.0). Grade 3-4 hematologic AEs included neutropenia (27%) and thrombocytopenia (39%). The B-FC regimen has satisfactory responses and manageable toxicities in rrMCL patients (ClinicalTrials.gov NCT01322776).Myeloproliferative neoplasms are rare at a young age, and few reports have described the disease characteristics and outcomes in this group. This study aimed to elucidate the clinical course of essential thrombocythemia (ET) and polycythemia vera (PV) in children and young adults aged less then 39 years focusing on thromboembolic events (TE) and second primary malignancies (SPMs). A total of 990 patients who were diagnosed from 2008 to 2017 were included by analyzing the Health Insurance Review and Assessment Service database in Korea. The incidence was 2.53 per 1,000,000 for ET (643 patients; 276 male patients; median 31 years) and 1.37 per 1,000,000 for PV (347 patients; 309 male patients; median 32 years). Three ET patients developed secondary acute myelogenous leukemia and three developed secondary myelofibrosis. The 5-year cumulative incidence of TE was 14.2% in ET and 21.3% in PV. Thus, the incidence was higher in PV; in particular, arterial TE (ATE) was evidently higher in PV than in ET. The 5-year cumulative incidence of SPMs was 2.5% in ET and 2.6% in PV. While the use of both aspirin and hydroxyurea reduced the incidence of ATE, hydroxyurea significantly increased the incidence of SPMs. The incidence of ET and PV was very low, and ET was more common than PV in children and young adults. CDK inhibitor The high incidence of TE in young patients suggests the importance of thrombosis prevention. However, hydroxyurea appears to increase the incidence of SPMs; therefore, the risks and benefits should be considered.The Drosophila Trithorax group (TrxG) protein ASH1 remains associated with mitotic chromatin through mechanisms that are poorly understood. ASH1 dimethylates histone H3 at lysine 36 via its SET domain. Here, we identify domains of the TrxG protein ASH1 that are required for mitotic chromatin attachment in living Drosophila. Quantitative live imaging demonstrates that ASH1 requires AT hooks and the BAH domain but not the SET domain for full chromatin binding in metaphase, and that none of these domains are essential for interphase binding. Genetic experiments show that disruptions of the AT hooks and the BAH domain together, but not deletion of the SET domain alone, are lethal. Transcriptional profiling demonstrates that intact ASH1 AT hooks and the BAH domain are required to maintain expression levels of a specific set of genes, including several involved in cell identity and survival. This study identifies in vivo roles for specific ASH1 domains in mitotic binding, gene regulation, and survival that are distinct from its functions as a histone methyltransferase.
Embryonal rhabdomyosarcoma (eRMS) is the most common type of rhabdomyosarcoma in children. eRMS is characterized by malignant skeletal muscle cells driven by hyperactivation of several oncogenic pathways including the MYC pathway. Targeting MYC in cancer has been extremely challenging. Recently, we have demonstrated that the heart failure drug, proscillaridin A, produced anticancer effects with specificity toward MYC expressing leukemia cells. We also reported that decitabine, a hypomethylating drug, synergizes with proscillaridin A in colon cancer cells. Here, we investigated whether proscillaridin A exhibits epigenetic and anticancer activity against eRMS RD cells, overexpressing MYC oncogene, and its combination with decitabine.

We investigated the anticancer effects of proscillaridin A in eRMS RD cells in vitro. In response to drug treatment, we measured growth inhibition, cell cycle arrest, loss of clonogenicity and self-renewal capacity. We further evaluated the impact of proscillaridin A on MYC exp (lysine 9, 14, 18, and 27 on histone 3) was associated with significant protein downregulation of a series of lysine acetyltransferases (KAT3A, KAT3B, KAT2A, KAT2B, and KAT5). In addition, proscillaridin A produced synergistic growth inhibition and loss of clonogenicity when combined with the approved DNA demethylating drug decitabine.

Proscillaridin A produces anticancer and epigenetic effects in the low nanomolar range and its combination with decitabine warrants further investigation for the treatment of eRMS.

The aim of this study was to evaluate effectiveness and safety of resistance training (RT). Data were retrieved from Medline, EMBASE, PubMed, CINAHL and Cochrane Central Register of Controlled Trials (Central) databases from inception to April 2020. Quantitative studies on RT for muscle strength, lean body mass, cardiopulmonary function, metabolism, quality of life, and pain in burned children were included in this study. Twelve RCTs (379 patients) were identified. Meta-analysis showed RT significant increase in muscle strength [SMD = 2.18, 95% CI (0.79, 3.56), p = 0.002]. However, training showed no significant effect on muscle endurance [MD = 10.00, 95% CI (-0.22, 20.22), p = 0.06]. Notably, training significantly increases total lean body mass [MD = 2.10, 95% CI (1.28, 2.92), p < 0.001]. In addition, training significantly increased leg lean body mass [MD = 2.10, 95% CI (1.28, 2.92), p < 0.001]. Moreover, training significantly increased VO
peak [MD = 5.83, 95% CI (3.52, 8.13), p < 0.001]. Metang significantly improves walking speed (p = 0.0008). Notably, all studies showed unclear or high risk of bias; whereas, quality of the evidence was moderate or low. Analysis showed that RT significantly improves clinical outcomes. However, more high-quality, double-blind, randomized control trials should be performed to explore the effects of RT to ensure successful implementation in rehabilitation.Fish contaminant studies with human health protection objectives typically focus on muscle tissue, recognizing that fillets are the commonly consumed tissue fraction. Muscle biopsy punch sampling for mercury analysis has recently been used as an alternative to harvesting fish for fillets; however, there is limited information comparing fillet plug results to whole fillet results. This study was conducted to address that data gap and to test the applicability of plugs for monitoring associated with United States Environmental Protection Agency's fish tissue-based mercury and selenium water quality criteria. The mercury phase included 300 fillet homogenates and 300 field-extracted plug samples from 60 fish, and the selenium phase included 120 fillet homogenates and 120 plugs from 30 fish. Both phases showed that there were no statistically significant differences between fillet plug and homogenized fillet results at the community level; however, a selenium plug monitoring alternative must employ a sufficiently sensitive analytical method and consider total solids.
