Abstract
During a dual-center study on obese and normal weight children and adolescents, focusing on glucose metabolism, we observed a marked difference in glucose results (N = 16,840) between the two sites, Salzburg, Austria and Uppsala, Sweden (P < 0.001). After excluding differences in patient characteristics between the two populations as cause of this finding, we investigated other preanalytic influences. Finally, only the tubes used for blood collection at the two sites were left to evaluate. While the Vacuette FC-Mix tube (Greiner Bio-One, Kremsmünster, Austria) was used in Uppsala, in Salzburg blood collections were performed with a lithium heparin tube (LH-Monovette, Sarstedt, Germany). To prove our hypothesis, we collected two blood samples in either of these tubes from 51 children (Salzburg N = 27, Uppsala N = 24) and compared the measured glucose results. Indeed, we found the suspected bias and calculated a correction formula, which significantly diminished the differences of glucose results between the two sites (P = 0.023). Our finding is in line with those of other studies and although this issue should be widely known, we feel that it is widely neglected, especially when comparing glucose concentrations across Europe, using large databases without any information on preanalytic sample handling.

[Prevalence of prediabetes and its comorbidities in the Mexican pediatric population]. NUTR HOSP 2021; 38:722-728.

Abstract
Introduction Background: prediabetes is a state observed before type-2 diabetes. Nowadays the obesity epidemic could be due to a rise in the incidence of prediabetes. Mexico has public policies for the management of non-communicable diseases. However, obesity rates continue to increase. The aim of this study was to elaborate on a diagnosis of prediabetes in the pediatric Mexican population, and compare the proportions of comorbidities that children with and without prediabetes had. Methods: a cross-sectional study was performed with 569 participants of 4 to 19 years of age from public schools. Anthropometric (weight, height, and waist circumference), clinical (blood pressure), and biochemical (fasting glucose, lipidic profile, and uric acid) variables were collected. Results: in all, 8.6 % of the population had prediabetes. Variables with the highest altered prevalence included triglycerides and systolic blood pressure. Boys had higher rates of prediabetes, altered BP, and hyperuricemia than girls. Children with prediabetes had a greater risk of elevated waist circumference, blood pressure, and uric acid measures. Conclusions: the Mexican pediatric population had elevated rates of prediabetes. Furthermore, the group with prediabetes had a higher risk of presenting high values of triglycerides, blood pressure, uric acid, and total cholesterol.

Abstract
Background There is growing concern as regards the emergence of metabolic disorders among children living with the Human Immunodeficiency Virus (HIV) worldwide. However, there is paucity of data on the correlates of metabolic indices among HIV-positive children in Africa. Methods This study examined 84 HIV-positive children on HAART recruited from the paediatric infectious diseases clinic of the University of Nigeria Teaching Hospital for blood glucose levels using finger-prick testing with an Accu-check glucose meter and test strips. Clinical information was obtained via clinical history and medical records. Data was analyzed to examine the relationship between FBG and the classes of HAART, duration of illness and treatment using analysis of variance (ANOVA). Results FBG was significantly associated with the classes of HAART (x2=12.4, p = 0.017). In addition, there was a significant association between FBG and duration of illness [F(2, 81) = 6.0; P = 0.004], as well as FBG and duration on HAART [F(2, 81) = 7.9; P = 0.001]. However, duration on HAART and type of HAART were the significant predictors of FBG in this study accounting for 10.5% and 4.1% of the variance, respectively. Conclusions There is a greater risk of dysglycemia in paediatric patients with a longer cumulative exposure to HAART. Routine blood glucose checks among children on HAART, especially those who have received HAART for a longer duration of time may therefore be useful in their management.

Schick EE, Segura LE, Emamjomeh S, Cotter JA. The Effect of Resistance Exercise Intensity on Acute Hyperglycemia in Young Adult Males. Sports (Basel) 2020; 8:sports8090121. [PMID: 32899107 PMCID: PMC7552604 DOI: 10.3390/sports8090121] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Revised: 08/27/2020] [Accepted: 08/31/2020] [Indexed: 11/16/2022] Open
Abstract
The purpose of this study was to examine the effect of resistance exercise (RE) intensity on acute hyperglycemia, in young adult males. Thirteen males (age 23.43 ± 2.18 years, height 175.16 ± 10.44 cm, weight 77.02 ± 8.91 kg, body fat 20 ± 0.03%) participated in three randomized testing sessions, each separated by 96 h. The three testing conditions were: control (CON; induction of hyperglycemia with no-exercise), high (HI; induction of hyperglycemia followed by high-intensity RE: 5 × 4, 90% 1-repetition maximum (1-RM)), and moderate (MO; induction of hyperglycemia followed by low-intensity RE: 3 × 14, 65% 1-RM). In all three testing conditions, participants orally ingested a D100 (100 g/10 oz) glucose beverage at a dosage of 2 g glucose/kg body weight and capillary blood was obtained for plasma glucose and insulin analysis at 0 (fasting), 30, 60, 90 and 120 min, following glucose ingestion. At 30-min post-ingestion in the HI and MO conditions, participants began the respective RE protocols. Acute hyperglycemia was achieved throughout all three 2-h testing conditions; mean 2-h plasma glucose levels during CON (7.1 ± 1.3 mmol∙L−1), MO (7.5 ± 0.6 mmol∙L−1) and HI (8.2 ± 1.9 mmol∙L−1) were all significantly (p < 0.05) greater than mean fasting plasma glucose (5.6 ± 0.46 mmol∙L−1). Plasma glucose and insulin did not differ (p < 0.05) between treatment conditions at any times points over the 120 min, however, 2-h glucose area under the curve in the HI condition was significantly greater (p < 0.05) than CON and MO. In conclusion, this study indicates that hyperglycemia, induced prior to RE, may be exacerbated by high-intensity RE.
