Pretherapy 18F-fluorodeoxyglucose positron emission tomography/computed tomography robust radiomic features predict overall survival in non-small cell lung cancer.

Objective: To extract robust radiomic features from staging positron emission tomography/computed tomography (18F- fluroodeoxyglucose PET/CT) in patients with non-small cell lung cancer from different segmentation methods and to assess their association with 2-year overall survival.

Methods: Eighty-one patients with stage I-IV non-small cell lung cancer were included. All patients underwent a pretherapy 18F-FDG PET/CT.

Two-bed SPECT/CT versus planar bone scintigraphy: prospective comparison of reproducibility and diagnostic performance.

Objective: To evaluate the reproducibility and diagnostic performance of two-bed single-photon emission computed tomography/computed tomography (SPECT/CT) images (TBSCT), compared to conventional planar bone scintigraphy (PBS) for the diagnosis of osseous metastasis.

Methods: Patients with known solid tumor, referred to perform PBS, were included in this prospective study. PBS acquisition was followed by TBSCT images, covering at least the chest, abdomen and pelvis.

The role of serum nuclear factor erythroid 2-related factor 2 in childhood bronchial asthma.

Asthma is one of the most common chronic airway disease of childhood. Poor asthma control has been associated with antioxidant deficiencies. To assess the association of bronchial asthma in Egyptian children with serum nuclear factor erythroid 2-related factor2 (NRF2) and its relation to disease severity.

Oxidative stress contribution to attention deficit hyperactivity disorder in children with epilepsy.

Children with epilepsy have a high incidence of attention deficit hyperactivity disorder (ADHD). Oxidation stress and disturbed neurotransmitters are suggested mechanisms; however, their role is not fully explored. This study evaluates the association between circulating malondialdehyde as an oxidation stress marker, apelin neuropeptide, and ADHD in children with epilepsy.

Circulating irisin and chemerin levels as predictors of seizure control in children with idiopathic epilepsy.

Irisin and chemerin peptides expression are triggered by hypoxia and involved in activation of inflammatory cascades in various organs including the brain; however, their role in epilepsy is not fully illustrated. This study aims to explore the predictive role of irisin and chemerin for seizure control in children with idiopathic epilepsy. This cross-sectional comparative study included 50 children with idiopathic epilepsy; 25 of them had controlled seizures over the previous 6 months and 30 age- and sex-matched healthy children as controls.
