(
) wild-type lower-grade gliomas (histologic grades II and III) with
(
) amplification or
(
) promoter mutation are reported to behave similar to glioblastoma. Citarinostat cost We aimed to evaluate whether MR imaging features could identify a subset of
wild-type lower-grade gliomas that carry molecular features of glioblastoma.

In this multi-institutional retrospective study, pathologically confirmed
wild-type lower-grade gliomas from 2 tertiary institutions and The Cancer Genome Atlas constituted the training set (institution 1 and The Cancer Genome Atlas, 64 patients) and the independent test set (institution 2, 57 patients). Preoperative MRIs were analyzed using the Visually AcceSAble Rembrandt Images and radiomics. The molecular glioblastoma status was determined on the basis of the presence of
amplification and
promoter mutation. Molecular glioblastoma was present in 73.4% and 56.1% in the training and test sets, respectively. Models using clinical, Visually AcceSAble Rembrandt Images, and radiomic features were built to predict the molecular glioblastoma status in the training set; then they were validated in the test set.

In the test set, a model using both Visually AcceSAble Rembrandt Images and radiomic features showed superior predictive performance (area under the curve = 0.854) than that with only clinical features or Visually AcceSAble Rembrandt Images (areas under the curve = 0.514 and 0.648, respectively;
 < . 001, both). When both Visually AcceSAble Rembrandt Images and radiomics were added to clinical features, the predictive performance significantly increased (areas under the curve = 0.514 versus 0.863,
 < .001).

MR imaging features integrated with machine learning classifiers may predict a subset of
wild-type lower-grade gliomas that carry molecular features of glioblastoma.

Tpt1 performs a two-step reaction in which (i) the 2'-PO4 attacks NAD+ to form an RNA-2'-phospho-(ADP-ribose) intermediate; and (ii) transesterification of the ADP-ribose O2'' to the RNA 2'-phosphodiester yields 2'-OH RNA and ADP-ribose-1'',2''-cyclic phosphate. Because Tpt1 does not participate in metazoan tRNA splicing, and Tpt1 knockout has no apparent impact on mammalian physiology, Tpt1 is considered a potential anti-fungal drug target. Here we characterize Tpt1 enzymes from four human fungal pathogens Coccidioides immitis, the agent of Valley Fever; Aspergillus fumigatus and Candida albicans, which cause invasive, often fatal, infections in immunocompromised hosts; and Candida auris, an emerging pathogen that is resistant to current therapies. All four pathogen Tpt1s were active in vivo in complementing a lethal Saccharomyces cerevisiae tpt1∆ mutation and in vitro in NAD+-dependent conversion of a 2'-PO4 to a 2'-OH. The fungal Tpt1s utilized nicotinamide hypoxanthine dinucleotide as a substrate in lieu of NAD+, albeit with much lower affinity, whereas nicotinic acid adenine dinucleotide was ineffective. Fungal Tpt1s efficiently removed an internal ribonucleotide 2'-phosphate from an otherwise all-DNA substrate. Replacement of an RNA ribose-2'-PO4 nucleotide with arabinose-2'-PO4 diminished enzyme specific activity by ≥2000-fold and selectively slowed step 2 of the reaction pathway, resulting in transient accumulation of an ara-2'-phospho-ADP-ribosylated intermediate. Our results implicate the 2'-PO4 ribonucleotide as the principal determinant of fungal Tpt1 nucleic acid substrate specificity.ObjectivesOur large-scale cluster randomised controlled trial aimed to investigate the effects on health knowledge and enjoyment of an 11 week 'health education through football' programme for children aged 10-12 years old.Methods3127 Danish school children (49% girls) aged 10-12 years from a total of 154 schools located in 63% of the Danish municipalities (69 of 98) took part in the analysis. A 51 cluster randomisation was performed at school level for the intervention group (IG) or the control group (CG). The twice-weekly 45 min intervention was the '11 for Health in Denmark' programme, which includes health education, football drills and small-sided games. The health education element focused on hygiene, nutrition, physical activity and well-being. Outcomes The participants completed a 34-item multiple-choice computer-based health knowledge questionnaire preintervention and postintervention. IG also evaluated whether the programme was enjoyable.ResultsBetween-group differences (p less then 0.05) were observed in overall health knowledge in favour of IG (+7.2% points, 95% CI 6.1% to 8.4%, effect size, ES0.59), with similar effects for girls (+7.4% points, 95% CI 5.9% to 9.0%, ES0.57) and for boys (+7.0% points, 95% CI 5.3% to 8.7%, p less then 0.05, ES0.51). Marked between-group differences were observed in favour of IG, for health knowledge related to hygiene (IG vs CG+13.9% points, 95% CI 11.1% to 16.7%, ES0.53), nutrition (+10.3% points, 95% CI 8.5% to 12.1%, ES0.53), physical activity (+5.9% points, 95% CI 4.1% to 7.7%, ES0.36) and well-being (+4.4% points, 95% CI 2.7% to 6.1%, ES0.28). Both girls and boys gave the programme moderate to high scores for enjoyment (3.6±1.0 and 3.7±1.1, respectively).ConclusionHealth education through sport, using the '11 for Health' model, was enjoyable for girls and boys aged 10-12 years old, and improved health knowledge related to hygiene, nutrition, physical activity and well-being.Topics for DTB review articles are selected by DTB's editorial board to provide concise overviews of medicines and other treatments to help patients get the best care. Articles include a summary of key points and a brief overview for patients. Articles may also have a series of multiple choice CME questions.Ovarian clear cell carcinoma (OCCC) is a rare, chemo-resistant subtype of ovarian cancer. To identify novel therapeutic targets and combination therapies for OCCC, we subjected a set of patient-derived ovarian cancer cell lines to arrayed high-throughput siRNA and drug screening. The results indicated OCCC cells are vulnerable to knockdown of epigenetic gene targets such as bromodomain and extra-terminal domain (BET) proteins BRD2 and BRD3. Subsequent RNA interference assays, as well as BET inhibitor treatments, validated these BET proteins as potential therapeutic targets. Because development of resistance to single targeted agents is common, we next performed sensitizer drug screens to identify potential combination therapies with the BET inhibitor CPI0610. Several PI3K or AKT inhibitors were among the top drug combinations identified and subsequent work showed CPI0610 synergized with alpelisib or MK2206 by inducing p53-independent apoptosis. We further verified synergy between CPI0610 and PI3K-AKT pathway inhibitors alpelisib, MK2206, or ipatasertib in tumor organoids obtained directly from patients with OCCC.
