Background Although brain-derived neurotrophic factor(BDNF)has been identified as a molecular biomarker of the neurophysiological effects induced by exercise,the acute effects of high-intensity exercise(HIE)on BDNF levels are *** study aims to estimate the immediate effects of HIE on BDNF levels in healthy young *** A systematic search was conducted in the MEDLINE,Scopus,Cochrane CENTRAL,and SPORTDiscuss databases up to December *** controlled trials(RCTs)and non-RCTs reporting pre-post changes in serum or plasma BDNF after an acute intervention of HIE compared to a control condition were *** effect sizes(p-ESs)and 95%confidence intervals(95%CIs)were calculated for RCTs using a random effects model with Stata/SE(Version 15.0;StataCorp.,College Station,TX,USA).The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were *** registration number:*** A total of 22 studies with 552 individuals(age range:20-31 years;59.1%male)were *** meta-analysis included 10 RCTs that reported valid outcome *** BDNF levels were observed when HIE interventions were compared with non-exercise(p-ES=0.55,95%CI:0.12-0.98;I^(2)=25.7%;n=4 studies)and light-intensity exercise(p-ES=0.78,95%CI:0.15-1.40;I^(2)=52.4%;n=3 studies)but not moderate-intensity exercise(p-ES=0.93,95%CI:-0.16 to 2.02;I^(2)=88.5%;n=4 studies)*** In comparison to non-exercise or light-intensity exercises,an immediate increase in BDNF levels may occur when young adults perform *** the benefits obtained maximizing circulating BDNF when performing HIE and its potential effects on brain health,our findings suggest that HIE could be recommended by clinicians as a useful exercise strategy to healthy adults.

AIM To assess proportions, related conditions and survival of interval cancer(IC).METHODS The programme has a linkage with different clinical databases and cancer registers to allow suitable evaluation. This evaluation involves the detection of ICs after a negative faecal inmunochemical test(FIT), interval cancer FIT(IC-FIT) prior to a subsequent invitation, and the detection of ICs after a positive FIT and confirmatory diagnosis without colorectal cancer(CRC) detected and before the following recommended c o l o n o s c o p y, I C-c o l o n o s c o p y. W e c o n d u c t e d a retrospective observational study analyzing from January 2009 to December 2015 1193602 invited people onto the Programme(participation rate of 68.6%).RESULTS Two thousand five hundred and eighteen cancers were diagnosed through the programme, 18 cases of IC-colonoscopy were found before the recommended follow-up(43542 colonoscopies performed) and 186 IC-FIT were identified before the following invitation of the 769200 negative FITs. There was no statistically significant relation between the predictor variables of ICs with sex, age and deprivation index, but there was relation between location and stage. Additionally, it was observed that there was less risk when the location was distal rather than proximal(OR = 0.28, 95%CI: 0.20-0.40, P < 0.0001), with no statistical significance when the location was in the rectum as opposed to proximal. When comparing the screen-detected cancers(SCs) with ICs, significant differences in survival were found(P < 0.001); being the 5-years survival for SCs 91.6% and IC-FIT 77.8%.CONCLUSION These findings in a Population Based CRC Screening Programme indicate the need of population-based studies that continue analyzing related factors to improve their detection and reducing harm.
