Skeletal muscle as a pro- and anti-inflammatory tissue: insights from children to adults and ultrasound findings.

Previously regarded as a movement and posture control agent, the skeletal muscle is now recognized as an endocrine organ that may affect systemic inflammation and metabolic health. The discovery of myokines such as IL-6, released from skeletal muscle in response to physical exercise, is now one of the most recent insights. Myokines are the mediators of the balance between the pro-inflammatory and anti-inflammatory responses.

Effects of COVID-19 time on the development of pre-impaired glucose tolerance state in children and adolescents with overweight and obesity.

Objectives: We aimed to characterize the effects of COVID-19 Pandemic on 2 h plasma glucose (2 h PG) values after an OGTT postulating a correlation between 2 h PG spectrum and the decline of β-cell function. Particularly, we tried to evaluate the effects on the risk of showing 2 h plasma glucose values in the highest range of normal values in children and adolescent with obesity during COVID-19 Pandemic compared to those evaluated during the 13 years before.

Subjects/methods: Data from 532 children and adolescents with obesity and overweight (before COVID-19 Pandemic, 209M/262F, 2008-2019; during COVID-19 Pandemic, 40M/21F, 2020-2021) who had undergone a complete evaluation and had performed an OGTT were analyzed.

Insulin resistance relates to DKA severity and affects insulin requirement in children with type 1 diabetes at onset.

Background: Fluid and insulin treatments are the cornerstones of DKA management and indications on dosages are available. However, according to possible confounding factors, relevant data are still required to explain the different insulin dosages adopted at diabetes onset, particularly based upon insulin sensitivity.

Objective: We aimed to explore whether DKA severity is related to different insulin sensitivity states, thus resulting in different insulin requirement at diabetes onset.

The bad rainbow of COVID-19 time: effects on glucose metabolism in children and adolescents with obesity and overweight.

Background: COVID-19 restriction measurements have enhanced the obesity status in the pediatric population which might further contribute to obesity-related glucose-insulin metabolism alterations. Therefore, we retrospectively compared anthropometric and OGTT data on children with obesity during the 13 years before and during the COVID-19 pandemic.

Subjects/methods: Data from 741 children with obesity and overweight were retrieved and clustered into seven groups starting from year 2008-2009 until 2020-2021.

Metabolic Changes across Tertiles of Delta Changes in Height SDS during Growth Hormone Therapy in Children with Growth Hormone Deficiency.

Introduction: Obesity, dyslipidemia, hypertension, and insulin resistance are components of the metabolic syndrome and in adults are positively affected by growth hormone (GH) treatment. Few data are available on youth, especially evaluating the improvement of metabolic features after starting GH treatment. The aim of this study was to evaluate changes in metabolic profile in GHD children across tertiles of h-SDS changes after at least 20 months of GH therapy.
