Unraveling the humanity in metacognitive ability: Distinguishing human metalearning from AI uoftsukuba NatureComms

). The meta-learning training phase consisted of 6 cycles of 10 Null trials followed by five pairs of E and R trials . +5° rotation was used in E. Since the learner received the reward feedback in R for multiple trials in the training phase, the updated memory after the first R trial is potentially influenced by the accumulation of a reward effect.

The experiments comprised four blocks. The first block contained a Probe phase followed by a meta-learning training phase and another Probe phase. The remaining blocks consisted of a meta-learning training phase followed by a Probe phase. 30 Null trials and one-minute breaks were inserted before and after each Probe phase. The score was removed in R trials in the first block to measure baseline behavior without reward feedback.as follows.

The association of hypoglycemia with outcome of critically ill children in relation to nutritional and blood glucose control strategies - Critical CareThe association of hypoglycemia with outcome of critically ill children in relation to nutritional and blood glucose control strategies - Critical CareBackground Withholding parenteral nutrition (PN) until one week after PICU admission facilitated recovery from critical illness and protected against emotional and behavioral problems 4 years later. However, the intervention increased the risk of hypoglycemia, which may have counteracted part of the benefit. Previously, hypoglycemia occurring under tight glucose control in critically ill children receiving early PN did not associate with long-term harm. We investigated whether hypoglycemia in PICU differentially associates with outcome in the context of withholding early PN, and whether any potential association with outcome may depend on the applied glucose control protocol. Methods In this secondary analysis of the multicenter PEPaNIC RCT, we studied whether hypoglycemia in PICU associated with mortality (N = 1440) and 4-years neurodevelopmental outcome (N = 674) through univariable comparison and multivariable regression analyses adjusting for potential confounders. In patients with available blood samples (N = 556), multivariable models were additionally adjusted for baseline serum NSE and S100B concentrations as biomarkers of neuronal, respectively, astrocytic damage. To study whether an association of hypoglycemia with outcome may be affected by the nutritional strategy or center-specific glucose control protocol, we further adjusted the models for the interaction between hypoglycemia and the randomized nutritional strategy, respectively, treatment center. In sensitivity analyses, we studied whether any association with outcome was different in patients with iatrogenic or spontaneous/recurrent hypoglycemia. Results Hypoglycemia univariably associated with higher mortality in PICU, at 90 days and 4 years after randomization, but not when adjusted for risk factors. After 4 years, critically ill children with hypoglycemia scored significantly worse for certain parent/caregiver-reported executive functions (working memory, planning and organization, metacognition)
