s was not statistically different. The number and quality of embryos were not significantly different in both groups. Our results indicated a significant relationship between the level of AMH and the number of retrieved oocytes and embryos. We found there is a significant correlation between cholesterol level and number of MI oocytes.
  10.5 with area under curve of 0.619±0.054(sensitivity 55.56% and specificity 69.66%) CONCLUSIONS The results of this study showed that although the number of oocytes in PCOS patients was significantly higher than non-PCOS patients, the quality of oocytes was not statistically different. The number and quality of embryos were not significantly different in both groups. Our results indicated a significant relationship between the level of AMH and the number of retrieved oocytes and embryos. We found there is a significant correlation between cholesterol level and number of MI oocytes.
  Brewers' spent grain (BSG) typically contains 20% - 29% crude protein (CP) with high concentrations of glutamine, proline and hydrophobic and non-polar amino acid, making it an ideal material for producing value-added products like bioactive peptides which have antioxidant properties. For this study, protein was extracted from BSG, hydrolyzed with 1% alcalase and flavourzyme, with the generated protein hydrolysates (AlcH and FlaH) showing antioxidant activities. This study evaluated the effects of AlcH and FlaH on gas production, ruminal fermentation characteristics, nutrient disappearance, microbial protein synthesis and microbial community using an artificial rumen system (RUSITEC) fed a high-grain diet.
 
  As compared to the control of grain only, supplementation of FlaH decreased (P< 0.01) disappearances of dry matter (DM), organic matter (OM), CP and starch, without affecting fibre disappearances; while AlcH had no effect on nutrient disappearance. Neither AlcH nor FlaH affected gas production or VFA, Shuttleworthia, Bifidobacterium and Dialister as compared to control; monensin reduced (P< 0.05) RA of genus Prevotella but enhaced Succinivibrio.
 
  The supplementation of FlaH in high-grain diets may potentially protect CP and starch from ruminal degradation, without adversely affecting fibre degradation and VFA profiles. It also showed promising effects on reducing CH
  production by suppressing H
  production. Protein enzymatic hydrolysates from BSG using flavourzyme showed potential application to high value-added bio-products.

  As Alzheimer's disease (AD) pathology presents decades before dementia manifests, unbiased biomarker cut-points may more closely reflect presence of pathology than clinically defined cut-points. Currently, unbiased cerebrospinal fluid (CSF) tau cut-points are lacking.
 
  We investigated CSF t-tau and p-tau cut-points across the clinical spectrum using Gaussian mixture modelling, in two independent cohorts (Amsterdam Dementia Cohort and ADNI).
 
  Individuals with normal cognition (NC) (total n= 1111), mild cognitive impairment (MCI) (total n= 1213) and Alzheimer's disease dementia (AD) (total n= 1524) were included. In both cohorts, four CSF t- and p-tau distributions and three corresponding cut-points were identified. Increasingly high tau subgroups were characterized by steeper MMSE decline and higher progression risk to AD (cohort/platform-dependent HR, t-tau 1.9-21.3; p-tau 2.2-9.5).
 
  The number of subjects in some subgroups and subanalyses was small, especially in the highest tau subgroup and in tau PET analyses.
 
  In two independent cohorts, t-tau and p-tau levels showed four subgroups. Increasingly high tau subgroups were associated with faster clinical decline, suggesting our approach may aid in more precise prognoses.

  Critically ill patients with coronavirus disease 19 (COVID-19) have a high fatality rate likely due to a dysregulated immune response. Corticosteroids could attenuate this inappropriate response, although there are still some concerns regarding its use, timing, and dose.
 
  This is a nationwide, prospective, multicenter, observational, cohort study in critically ill adult patients with COVID-19 admitted into Intensive Care Units (ICU) in Spain from 12th March to 29th June 2020. Using a multivariable Cox model with inverse probability weighting, we compared relevant outcomes between patients treated with early corticosteroids (before or within the first 48h of ICU admission) with those who did not receive early corticosteroids (delayed group) or any corticosteroids at all (never group). Primary endpoint was ICU mortality. Secondary endpoints included 7-day mortality, ventilator-free days, and complications.
 
  A total of 691 patients out of 882 (78.3%) received corticosteroid during their hospital stay. Patients treated with early-corticosteroids (n = 485) had lower ICU mortality (30.3% vs. never 36.6% and delayed 44.2%) and lower 7-day mortality (7.2% vs. never 15.2%) compared to non-early treated patients. They also had higher number of ventilator-free days, less length of ICU stay, and less secondary infections than delayed treated patients. There were no differences in medical complications between groups. Of note, early use of moderate-to-high doses was associated with better outcomes than low dose regimens.
 
  Early use of corticosteroids in critically ill patients with COVID-19 is associated with lower mortality than no or delayed use, and fewer complications than delayed use.
