Post-translational modifications (PTMs) are closely linked to numerous diseases, playing a significant role in regulating protein structures, activities, and functions. Therefore, the identification of PTMs is crucial for understanding the mechanisms of cell biology and diseases therapy. Compared to traditional machine learning methods, the deep learning approaches for PTM prediction provide accurate and rapid screening, guiding the downstream wet experiments to leverage the screened information for focused studies. In this paper, we reviewed the recent works in deep learning to identify phosphorylation, acetylation, ubiquitination, and other PTM types. In addition, we summarized PTM databases and discussed future directions with critical insights.

OBJECTIVE: To evaluate the individual use and predictive value of focused echocardiography, end-tidal carbon dioxide (EtCO2), invasive arterial blood pressure (BP) and near-infrared spectroscopy (NIRS) during cardiopulmonary resuscitation (CPR) in children.
METHODS: This scoping review was undertaken as part of the continuous evidence evaluation process of the International Liaison Committee on Resuscitation (ILCOR) and based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) extension for scoping reviews. PubMed, MEDLINE, CINAHL and EMBASE were searched from the last ILCOR reviews until September 2020. We included all published studies evaluating the effect of echocardiography, EtCO2, BP or NIRS guided CPR on clinical outcomes and quality of CPR.
RESULTS: We identified eight observational studies, including 288 children. Two case series reported the use of echocardiography, one in detecting pulmonary emboli, the second in cardiac standstill, where contractility was regained with the use of extracorporeal membrane oxygenation. The two studies describing EtCO2 were ambivalent regarding the association between mean values and any outcomes. Mean diastolic BP was associated with increased survival and favourable neurological outcome, but not with new substantive morbidity in two studies describing an overlapping population. NIRS values reflected changes in EtCO2 and cerebral blood volume index in two studies, with lower values in patients who did not achieve return of circulation.
CONCLUSIONS: Although there seems some beneficial effect of these intra-arrest variables, higher quality paediatric studies are needed to evaluate whether echocardiography, EtCO2, BP or NIRS guided CPR could improve outcomes.

OBJECTIVE: Several studies have been conducted on the accuracy of simplified criteria for autoimmune hepatitis that were presented in 2008 as an alternative to original criteria. Our purpose is to summarize the evidence available regarding their accuracy in children and to carry out a basic clinical decision analysis based on it.
METHODS: Electronic and manual searches were performed with keywords related to diagnostic validity terms. Data from included studies were extracted, and summary estimates of accuracy measures were calculated. An effect model was chosen depending on heterogeneity, and the presence of publication bias was also studied. Therapeutic threshold was calculated based on the already published data. Through a Bayesian approach, simplified criteria\'s clinical utility was simulated, taking into account the meta-analyzed indicators and several assumptions on the prevalence of autoimmune hepatitis.
RESULTS: The search yielded 166 studies, four of which were finally included, providing a total population of 437 patients. Pooled sensitivity and specificity of the simplified criteria for the diagnosis of autoimmune hepatitis in children was 77% and 95%, respectively, with a diagnostic odds ratio of 67. No evidence of publication bias was found. For prevalences ranging from 8.5 to 85.7, the predictive value of either a positive or a negative result moved beyond the therapeutic threshold (estimated at 56%).
CONCLUSIONS: The simplified criteria show high specificity and moderate sensitivity for the diagnosis of autoimmune hepatitis in children. A positive result can justify starting a therapeutic assay, but a negative result does not seem sufficient to rule out this condition.
