Objective: To determine the clinical characteristics and the predictors of hospital admission due to asthma among children and adolescents with asthma under treatment at a referral center.
Methods: A retrospective cohort study comprising 151 children and adolescents with asthma, referred from the Unified Health Care System and enrolled in the Asthma and Allergic Rhinitis Control Program in the city of Feira de Santana, Brazil, followed for a period of 12 months and receiving asthma medication at no cost. The chi-square test was used in order to determine the associations between the studied variables and the occurrence of hospital admissions, whereas the Mann-Whitney test was used for the comparison between the groups of hospitalized patients and nonhospitalized patients. The level of significance was set at p < 0.05. Univariate analysis with logistic regression was performed in order to determine the predictors of hospital admission.
Results: Of the 151 patients evaluated, 8 (5.2%) were hospitalized, in a total of 12 hospital admissions. In the univariate analysis, the only variable found to be a predictive factor was greater asthma severity (OR = 13.3; 95% CI: 2.55-70.1).
Conclusions: The fact that, in our study sample, the principal predictor of hospital admission was greater asthma severity, calls for special attention being given to the care of these patients.

Objective: Temporal encephaloceles (TEs) are seen in patients with drug-resistant epilepsy (DRE); yet they are also common incidental findings. Variability in institutional pre-surgical epilepsy practices and interpretation of epileptogenic network localization contributes to bias in existing epilepsy cohorts with TE, and therefore the relevance of TE in DRE remains controversial. We sought to estimate effect sizes and sample sizes necessary to demonstrate clinically relevant improvements in seizure outcome with different surgical approaches.

Background: Transjugular intrahepatic portosystemic shunt (TIPS) placement leads to a reduction in portal pressure and an improvement in survival in patients with recurrent and refractory ascites and variceal haemorrhage. Prediction of post-TIPS survival is primarily determined by factors identified before the TIPS procedure, as data collected during or after TIPS implantation are limited. The aim of the study was to evaluate the influence of early hemodynamic changes after TIPS placement on survival, in order to refine post TIPS management.

Background: The liver, as the main target organ for hematogenous metastasis of colorectal cancer, early and accurate prediction of liver metastasis is crucial for the diagnosis and treatment of patients. Herein, this study aims to investigate the application value of a combined machine learning (ML) based model based on the multiparameter magnetic resonance imaging for prediction of rectal metachronous liver metastasis (MLM).
Aim: To investigate the efficacy of radiomics based on multiparametric magnetic resonance imaging images of preoperative first diagnosed rectal cancer in predicting MLM from rectal cancer.

Background: Microvascular invasion (MVI) is a significant risk factor for recurrence and metastasis following hepatocellular carcinoma (HCC) surgery. Currently, there is a paucity of preoperative evaluation approaches for MVI.
Aim: To investigate the predictive value of texture features and radiological signs based on multiparametric magnetic resonance imaging in the non-invasive preoperative prediction of MVI in HCC.
