RESUMO

OBJECTIVE: To investigate fear of hypoglycemia (FoH) in parents of children with type 1 diabetes (T1D) before and after undergoing training to learn intranasal (IN) glucagon administration. METHOD: In this pre-test/post-test uncontrolled study 364 caregivers of patients with T1D (6-18 years) completed questionnaires measuring sociodemographic characteristics, diabetes-related factors (e.g., type of insulin therapy, glycemic control), and parents' trait anxiety. Parents' FoH was assessed at baseline (T0, training) and after nine months (T1). Two repeated-measure mixed analyses of covariance (ANCOVA) compared the FoH at T0 and at T1 and analyzed the moderating roles of anxiety proneness and type of insulin therapy, as well as of anxiety proneness and use of sensor. Age, T1D duration, HbA1c values, and SES were included as covariates. RESULTS: Parental FoH at T1 (M = 1.72; SE = 0.06/M = 1.57; SE = 0.09) was significantly lower than parental FoH at T0 (M = 1.89; SE = 0.06/M = 1.77; SE = 0.09). The group with high trait-anxiety had a higher level of FoH (M = 2.05; SE = 0.08/M = 1.89; SE = 0.12) than the group with low trait-anxiety (M = 1.57; SE = 0.08/M = 1.46; SE = 0.09) at both time points. SES was negatively associated with FoH at T0 (t = -2.87; p = .004/t = -2.87; p = .005). No other significant effects were found. CONCLUSIONS: Training and educating parents on IN glucagon use can help them effectively manage hypoglycemic episodes and alleviate the fear that generally accompany such events.

RESUMO

Traumatic spinal cord injuries (SCI) are a group of highly debilitating pathologies affecting thousands annually, and adversely affecting quality of life. Currently, no fully restorative therapies exist, and SCI still results in significant personal, societal and financial burdens. Inflammation plays a major role in the evolution of SCI, with myeloid cells, including bone marrow derived macrophages (BMDMs) and microglia (MG) being primary drivers of both early secondary pathogenesis and delayed wound healing events. The precise role of myeloid cell subsets is unclear as upon crossing the blood-spinal cord barrier, infiltrating bone marrow derived macrophages (BMDMs) may take on the morphology of resident microglia, and upregulate canonical microglia markers, thus making the two populations difficult to distinguish. Here, we used time-resolved scRNAseq and transgenic fate-mapping to chart the transcriptional profiles of tissue-resident and -infiltrating myeloid cells in a mouse model of thoracic contusion SCI. Our work identifies a novel subpopulation of foam cell-like inflammatory myeloid cells with increased expression of Fatty Acid Binding Protein 5 (Fabp5) and comprise both tissue-resident and -infiltrating cells. Fabp5+ inflammatory myeloid cells display a delayed cytotoxic profile that is predominant at the lesion epicentre and extends into the chronic phase of SCI.

RESUMO

OBJECTIVES: Hybrid closed loop systems (HCL) improve the management of type 1 diabetes (T1DM). T1DM adolescent patients represent a risk category also if they are in an automated insulin infusion delivery therapy. CASE PRESENTATION: We describe a series of four cases in which adolescent patients have adopted incorrect behaviours in the managing of HCL systems, challenging the algorithm skills. Two patients performed fabricated sensor calibrations. The other two did not perform pre-prandial insulin boluses correctly. Despite these behaviours, the algorithm corrected the glucose values in three out of four patients. Only in one case, where fabricated calibrations were too frequent, the automatic system failed to restore the glycemic balance. CONCLUSIONS: Fabricated calibrations seem to be more important than uncorrected insulin boluses to challenge the HCL systems.

RESUMO

BACKGROUND: When very low doses of insulin are used insulin dilution, a procedure prone to errors, is recommended. CASE PRESENTATION: We managed a neonate with pancreas agenesis with insulin pump therapy from the first days of life to 16 months of age without insulin dilution. Predictive low glucose suspend mode first and then closed loop control were used. No episodes of severe hypoglycemia were observed. CONCLUSIONS: Though limited to a single patient with pancreas agenesis we believe that the use of pump should be warranted in patients with permanent neonatal diabetes mellitus and intestinal malabsorption, even with undiluted insulin.

RESUMO

Wolfram Syndrome (WS) is a very rare genetic disorder characterized by several symptoms that occur from childhood to adulthood. Usually, the first clinical sign is non-autoimmune diabetes even if other clinical features (optic subatrophy, neurosensorial deafness, diabetes insipidus) may be present in an early state and may be diagnosed after diabetes' onset. Prognosis is poor, and the death occurs at the median age of 39 years as a consequence of progressive respiratory impairment, secondary to brain atrophy and neurological failure. The aim of this paper is the description of the metabolic treatment of the WS. We reported the experience of long treatment in patients with this syndrome diagnosed in pediatric age and followed also in adult age. It is known that there is a correlation between metabolic control of diabetes, the onset of other associated symptoms, and the progression of the neurodegenerative alterations. Therefore, a multidisciplinary approach is necessary in order to prevent, treat and carefully monitor all the comorbidities that may occur. An extensive understanding of WS from pathophysiology to novel possible therapy is fundamental and further studies are needed to better manage this devastating disease and to guarantee to patients a better quality of life and a longer life expectancy.

RESUMO

BACKGROUND: Recent research indicates that patients with type 1 diabetes (T1D) are at higher risk for disordered eating behaviors (DEBs) than their peers without diabetes. The present study aimed to explore the prevalence of DEBs in a sample of Italian children and adolescents with T1D and in matched-pair healthy controls during the COVID-19 lockdown. METHODS: In a cross-sectional study, 138 children and adolescents with T1D (aged 8.01-19.11 years, 65 boys) attending a Southern Italian diabetic service and 276 age- and gender-matched healthy peers voluntarily completed an online survey about eating behaviors (ChEAT and EAT-26), anthropometric characteristics, and clinical characteristics. RESULTS: 8.69% (N = 12) of participants with T1D and 13.4% (N = 37) of controls had ChEAT/EAT-26 scores indicating presence of DEBs, with no differences between patients-whether children (total ChEAT score F(1, 157) = .104, p = .748) or adolescents (total EAT-26 score F(1, 255) = .135, p = .731)-and healthy peers. zBMI values were lower than those measured in the latest diabetes visit (p < .0001), while HbA1c values remained unchanged (p = .110). In both groups, adolescents had lower Oral Control scores than children (T1D: F(1, 138) = 20.411, p < .0001, η2 = .132, controls: F(1, 276) = 18.271, p < .0001, η2 = .063); additionally, gender (female) and age were found to be significant predictors of several ChEAT/EAT-26 scores. CONCLUSIONS: This exploratory study suggested that children and adolescents with T1D did not experience more DEB symptoms during the COVID-19 lockdown compared to healthy controls. Results revealed DEBs as more of a female adolescent developmental issue rather than a result of the challenges of living with a chronic illness under quarantine measures. Possible effects of parental pressure on their children's eating behaviors in the context of home confinement and of using a non-diabetes-specific measure to assess DEBs are discussed.

RESUMO

Background: Glycemia following pizza consumption is typically managed with a dual-wave insulin bolus. This study evaluated the effect of a simple bolus on glycemia following consumption of traditionally prepared pizzas with long (24 h) or short (8 h) dough fermentation periods. Research Design and Methods: On two separate evenings, children with type 1 diabetes (n = 38) receiving sensor-integrated pump therapy consumed traditionally prepared pizza with either short (pizza A) or long (pizza B) dough fermentation, and blood glucose was monitored over 11 h. A simple insulin bolus was administered 15 min preprandially. The carbohydrate and amino acid contents of the two types of pizza were analyzed by liquid chromatography and high-resolution mass spectrometry (LC-HRMS). Results: The mean (±standard deviation) time in range 3.9-10.0 mmol/L was 73.2% ± 23.2%, and 50.8% ± 26.7% of glucose measurements were within the range 3.9-7.8 mmol/L. However, during the 2 h after bolus administration, the mean time in range 3.9-7.8 mmol/L was significantly greater with pizza B than with pizza A (73.3% ± 31.5% vs. 51.8% ± 37.4%, respectively, P = 0.009), and the time in hyperglycemia (>10 mmol/L) was significantly shorter (mean percentage 6.1% ± 19.0% vs. 17.7% ± 29.8%, respectively, P = 0.019). LC-HRMS analysis showed that long fermentation was associated with a lower carbohydrate content in the pizza, and a higher amino acid content. Conclusions: Glycemia following consumption of traditionally prepared pizza can be managed using a simple bolus 15 min before eating. Glycemic control can be further improved by increasing the dough fermentation time. Study registration: NCT03748251, Clinicaltrials.gov.
