To evaluate the utility of cardiac magnetic resonance feature tracking-derived left ventricular strain in assessing cardiac dysfunction and investigate the correlation between left ventricular strain and myocardial T2* in patients with beta-thalassaemia major.

Forty-two patients with beta-thalassaemia major, having a mean age of 22.49 ± 8.48 years, and age-matched healthy controls were enrolled in the study. The observer drew regions of interest on the interventricular septum, and T2* decay curves were calculated accordingly. The short-axis cine images were used to derive left ventricular circumferential and radial strains, and the long-axis four-chamber and two-chamber images were used to assess left ventricular longitudinal strain.

The mean global left ventricular strains were lower in beta-thalassaemia major patients than the controls (
 < 0.05). Left ventricular strains of beta-thalassaemia major patients with cardiac T2* values of > 20 ms were also significantly reduced compared with the conircumferential strain showed a good positive correlation with cardiac T2*.ImportanceLeft ventricular strain using cardiac magnetic resonance feature tracking might be used as an adjunct in assessing cardiac functions in beta-thalassaemia major.

The introduction of imatinib and tyrosine kinase inhibitors as therapeutic strategy for Philadelphia chromosome-positive chronic myeloid leukaemia (CML) has represented an important step forward for treatment of this disease. The aim of this study was therefore to evaluate the incidence of cardiovascular adverse events (CVEs) in patients affected by CML treated with TKI in an observational prospective study.

All consecutive patients affected by CML and treated with TKI in our Institution were enrolled in the study from February 2005 to September 2018 with a clinical, laboratory and instrumental follow-up.

Sixty-one consecutive patients were enrolled, 29 with imatinib, 15 with nilotinib, 11 with dasatinib, 3 with bosutinib and 3 with ponatinib. Neither patients in therapy with bosutinib nor with nilotinib had CVE during follow-up. Incidence rates per person/year were 0 for bosutinib and nilotinib, 0.15 for dasatinib, 0.19 for imatinib and 1.69 for ponatinib (Log Rank
 < 0.05); differences in terms of incidence of adverse outcomes remained significant also after multivariate correction.

In patients with CML treated with TKIs, therapy with ponatinib was associated with a higher risk of CVE than other TKIs. The lowest incidence of CVE was associated with bosutinib and nilotinib.

In this study, circRNA microarray analysis was utilized to screen differentially expressed circRNA in colorectal cancer (CRC) and circ_0000467 was identified as one circRNA whose expression was significantly upregulated in CRC. Quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) indicated that circ_0000467 and engrailed-2 (EN2) expression levels were up-modulated, while the expression level of miR-382-5p was down-modulated in CRC tissues. The depletion of circ_0000467 expression was found to impede the multiplication, migration, invasion, and epithelial-mesenchymal transition (EMT) processes in CRC cells, which were examined by 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) and Transwell experiments. Dual-luciferase reporter assay was used to verify the targeting relationship between circ_0000467 and miR-382-5p. Bafetinib in vivo It was also revealed that circ_0000467 could up-regulate EN2 expression via repressing miR-382-5p in CRC cells. Furthermore, EN2 overexpression counteracted the suppressing effects of circ_0000467 knockdown on the malignant behaviors of CRC cells. To sum up, circ_0000467 facilitates CRC development by modulating the miR-382-5p/EN2 axis, and circ_0000467 is a promising target for CRC therapy.Introduction Executive functions (EFs) impairment is common in children with neurofibromatosis type 1 (NF1), and could be a significant vulnerability associated with this medical disorder. However, we still know little about EFs in preschool NF1. Our study assessed EFs in NF1 children using performance-based tests and daily life questionnaires, which combined the views of parents and teachers.Method Seven classic experimental tasks were used to evaluate EFs in 33 NF1 children aged 3 to 5 years old, and BRIEF-P questionnaires were completed by their parents and teachers. These children's performance was compared with a control group of 52 healthy children matched in age, gender and socio-cultural status.Results NF1 children have significantly lower scores for 5 out of 7 executive tasks than control children and significantly higher levels of EF concerns in the parent and teacher BRIEF-P ratings. The correlations between performance-based tests and questionnaires are weak.Conclusions Our results support an early executive dysfunction in NF1 children and call for early and systematic assessment of EFs. Both performance-based tests and questionnaires are complementary tools to investigate early EFs dysfunction in children with NF1.The current pandemic of coronavirus disease (COVID) 2019 constitutes a global public health issue. Regarding the emerging importance of the gut-lung axis in viral respiratory infections, analysis of the gut microbiota's composition and functional activity during a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection might be instrumental in understanding and controling COVID 19. We used a nonhuman primate model (the macaque), that recapitulates mild COVID-19 symptoms, to analyze the effects of a SARS-CoV-2 infection on dynamic changes of the gut microbiota. 16S rRNA gene profiling and analysis of β diversity indicated significant changes in the composition of the gut microbiota with a peak at 10-13 days post-infection (dpi). Analysis of bacterial abundance correlation networks confirmed disruption of the bacterial community at 10-13 dpi. Some alterations in microbiota persisted after the resolution of the infection until day 26. Some changes in the relative bacterial taxon abundance associated with infectious parameters.
