Parent and child perceptions of physical activity with type 1 diabetes.

INTRODUCTION: Type 1 diabetes (T1D) is a lifelong illness that affects over 2500 children in Ireland. Management involves complex daily regimens including frequent blood glucose monitoring, pharmacotherapy, dietary management, and physical activity (PA). PA is an important modifiable lifestyle factor. Unfortunately, children with T1D remain physically inactive. Children with T1D face disease-specific barriers and facilitators to PA engagement. All aspects of T1D management for children are supported or supervised by parents. Thus, the purpose of this study was to examine parents' and children's perceptions of barriers and facilitators to PA engagement. RESEARCH DESIGN AND METHODS: 43 parent and child dyads participated. Parents completed a self-report survey. Children completed a modified version of the Physical Activity Questionnaire for Children (PAQ-C) that explored habitual PA patterns, perceived facilitators and barriers to PA engagement. RESULTS: 21 females, 22 males and their parents (36 mothers, 7 fathers) participated. 69% of males and 90% of females reported that having diabetes did affect their PA participation. 54% of males and 48% of females were insufficiently active based on their total PAQ-C score (<2.9 and <2.7). 53% of parents reported that their children participated in school physical education. 21% of parents reported that their child did not participate in PA outside of the school setting. 23% of parents reported that they did not feel comfortable with their child participating in strenuous PA. A further 30% of parents reported that they only felt comfortable with their child participating in strenuous PA if supervised. 66% of parents reported their child should be more physically active. 83% of parents reported that having T1D did impact their child's PA level. CONCLUSIONS: This study demonstrates the potential influence of parents' perceptions on PA engagement in children with T1D. Additional education is needed to support the promotion of PA for children with T1D.

Play, art, music and exercise therapy impact on children with diabetes.

Diabetes mellitus (DM) is a global public health issue. Type 1 diabetes (T1D) is the predominant diabetes type in children and always requires insulin therapy. The incidence rate of newly diagnosed T1D in children continues to increase in Ireland Roche et al. (Eur J Pediatr 175(12):1913-1919, 2016) and worldwide Patterson et al. (Diabetologia 62(3):408-417, 2019). The objective of this study was to conduct a literature review of the effects of various non-pharmacological therapeutic modalities on the control of diabetes in children. A literature review was performed using PubMed, Medline, Embase and Cochrane library to evaluate play, art, music and exercise therapy in the treatment of DM using the keywords: "paediatric", "diabetes", "play therapy", "art therapy", "music therapy" and "exercise therapy". These search terms initially returned 270 cases, which resulted in a total of 11 papers being reviewed after eliminating duplicate or irrelevant papers. Literature review showed that all therapies have a positive impact on the child, but there is limited research looking at the impact of therapy on quantitative measures such as HbA1c or 'time in range'.

Dyslipidaemia in Type 1 Diabetes: Molecular Mechanisms and Therapeutic Opportunities.

Cardiovascular disease (CVD) is the leading cause of death in Type 1 Diabetes (T1D). The molecular basis for atherosclerosis in T1D is heavily influenced by hyperglycaemia and its atherogenic effects on LDL. Ongoing research into the distinct pathophysiology of atherosclerosis in T1D offers exciting opportunities for novel approaches to calculate CVD risk in patients with T1D and to manage this risk appropriately. Currently, despite the increased risk of CVD in the T1D population, there are few tools available for estimating the risk of CVD in younger patients. This poses significant challenges for clinicians in selecting which patients might benefit from lipid-lowering therapies over the long term. The current best practice guidance for the management of dyslipidaemia in T1D is generally based on evidence from patients with T2D and the opinion of experts in the field. In this review article, we explore the unique pathophysiology of atherosclerosis in T1D, with a specific focus on hyperglycaemia-induced damage and atherogenic LDL modifications. We also discuss the current clinical situation of managing these patients across paediatric and adult populations, focusing on the difficulties posed by a lack of strong evidence and various barriers to treatment.

Glycaemic control improves after continuous subcutaneous insulin infusion therapy: results from an Irish regional centre for paediatric type 1 diabetes mellitus.

OBJECTIVES: The use of continuous subcutaneous insulin infusion (CSII) in the management of paediatric patients with type 1 diabetes mellitus (T1DM) has increased substantially in the last decade. The aim of this study was to evaluate and compare glycaemic control in a population of paediatric patients with T1DM before commencing CSII compared with 2 years after commencing CSII. METHODS: This is a retrospective study with data collection from diabetes clinic records. Complete data were obtained on 34/45 eligible patients. Glycosylated haemoglobin (HbA1c) and body mass index (BMI) were compared 6 months pre- and 2 years post CSII commencement. Data were stratified in 6-month blocks. RESULTS: Mean HbA1c improved over 2 years post CSII with the lowest value in the first 6 months post-commencement. When gender, age, time since diagnosis and time on pump were added as covariates, results became non-significant, with only age exhibiting a statistically significant influence on glycaemic control (p = 0.03). This improved glycaemic control is associated with some increment in BMI which showed no statistical significance in the first year post-CSII. CONCLUSION: CSII commencement is associated with significantly improved glycaemic control most notably in the first 6 months after CSII commencement. There is association between CSII commencement and increased BMI noted to be statistically significant in the second year.

Pregnancy outcomes in women with onset of type 1 diabetes mellitus less than 18 years of age.

BACKGROUND: Pregnancy in women with type 1 diabetes mellitus (T1DM) is associated with an increased risk of congenital malformations, obstetric complications and neonatal morbidity. This study aims to investigate maternal, perinatal and neonatal outcomes of pregnancies in women with onset of T1DM less than 18 years of age. METHODS: This retrospective cohort study extracted data regarding prenatal, intrapartum and postnatal outcomes of pregnancies in women with onset of T1DM<18 years identified from the diabetes in pregnancy register at University Maternity Hospital Limerick, treated from July 1, 2007 to July 1, 2017. RESULTS: Seventeen women with onset of T1DM <18 years gave birth to 23 live infants during the period studied. 73.9% of pregnancies were unplanned. Only 21.7% of pregnancies took preconceptual folic acid. 60.9% of infants required treatment for hypoglycemia. CONCLUSION: The high prevalence of unplanned pregnancy and poor uptake of prepregnancy care must be improved on in order to improve outcomes for this high-risk group.

A novel tool to predict youth who will show recommended usage of diabetes technologies.

BACKGROUND AND OBJECTIVE: Controversy exists regarding which individuals will benefit most from commencement of diabetes technologies such as continuous subcutaneous insulin infusion (CSII) or continuous glucose monitoring systems (CGMS), such as 'real-time' sensor-augmented pumping (SAP). Because higher usage correlates with haemoglobin A1c (HbA1c) achieved, we aimed to predict future usage of technologies using a questionnaire-based tool. SUBJECTS: The tool was distributed to two groups of youth with type 1 diabetes; group A (n = 50; mean age 12 ± 2.5 yr) which subsequently commenced 'real-time' CGMS and group B (n = 47; mean age 13 ± 3 yr) which commenced CSII utilisation. METHODS: For the CGMS group, recommended usage was ≥5 days (70%) per week [≥70% = high usage (HU); <70% = low usage (LU)], assessed at 3 months. In the CSII group, HU was quantified as entering ≥5 blood sugars per day to the pump and LU as <5 blood sugars per day, at 6 months from initiation. Binary logistic regression with forward stepwise conditional was used to utilise tool scales and calculate an applied formula. RESULTS: Of the CGMS group, using gender, baseline HbA1c, and two subscales of the tool generated a formula which predicted both high and low usage with 92% accuracy. Twelve (24%) showed HU vs. 38 who exhibited LU at 3 months. Of the CSII group, 32 (68%) exhibited HU vs. 15 who exhibited LU at 6 months. Four tool items plus gender predicted HU/LU with 95% accuracy. CONCLUSIONS: This pilot study resulted in successful prediction of individuals who will and those who will not go on to show recommended usage of CSII and CGMS.

Can integrated technology improve self-care behavior in youth with type 1 diabetes? A randomized crossover trial of automated pump function.

Automated blood glucose (BG) and insulin pump systems allow wireless transmission of all BG readings to a user's pump. This study aimed to assess whether use of such a system, as compared with a manual BG entry insulin pump, resulted in higher mean daily frequency of BGs recorded after 6 months. A 12-month randomized crossover trial, comprising 2 phases, was conducted. All participants used insulin pump devices with automated vs manual BG entry for 6 months each; order of system use was randomly assigned. Device interactions were assessed from pump and glucometer downloads. Thirty-five participants were enrolled; 9 withdrew during the study. Use of the automated insulin pump system resulted in higher mean daily BG recorded over 6 months of use when compared to a manual BG entry system (5.8 ± 1.7 vs 5.0 ± 1.9; P = .02 [95% confidence interval, 0.14 to 1.58]). Bolus frequency was similar between groups. No HbA1c difference was observed between groups at 6 months (8.0% [64 mmol/l] ± 1.3 automated vs 7.7% [61 mmol/l] ± 0.9 manual; P = .38). Post hoc analysis demonstrated improved ΔHbA1c with automated system use in an adolescent subgroup with suboptimal baseline BG frequency (-0.9% vs + 0.5%; P = .003). Use of an automated glucometer/insulin pump resulted in higher number of BGs recorded over 6 months when compared to an insulin pump with manual BG entry. This may be especially beneficial for adolescent manual system users who enter <5 BGs per day into their pump.

The Minimum Duration of Sensor Data From Which Glycemic Variability Can Be Consistently Assessed.

Despite much discussion regarding the clinical relevance of glycemic variation (GV), little discourse has addressed the properties of the data set from which it is derived. We aimed to assess the minimum duration of data required using continuous glucose monitoring (CGM) that most closely approximates to a gold standard 90-day measure. Data from 20 children and adolescents with type 1 diabetes were examined. All participants had CGM data sets of 90 days duration, from which standard deviation (SD), coefficient of variation (CV), mean amplitude of glycemic action (MAGE), and continuous overlapping net glycemic action (CONGA1-8) were calculated for the overall period and then investigational periods of 2, 4, 6, 12, 18, 24, and 30 days. The percentage difference between each measure and the overall measure per time period was assessed. As the duration of the CGM data set increased, the percentage error continued to decrease, giving a metric approximating more closely toward the overall measure. Median SD and CV differed from the overall measure by <10% at 12 days duration. The frequency of interruptions to the CGM trace rendered MAGE and CONGA unreliable, hence SD and CV were reported. We suggest that data sets used to infer GV should be of a minimum duration of 12 days. MAGE and CONGA exhibit poor performance in the setting of frequent trace interruption.

Exploring clinician confidence in the management of adolescent menstrual and reproductive health problems.

PURPOSE: A high incidence of menstrual problems is reported in adolescent girls, with significant attendant morbidity. The majority are likely to be seen and managed by doctors other than specialist gynaecologists. This study aimed to survey the practice of doctors other than gynaecologists, to establish their chosen therapeutic options and confidence levels and to explore knowledge, using clinically challenging scenarios. METHODS: A questionnaire designed to fulfil the above aims was distributed to a wide range of clinicians across paediatric disciplines and primary care. RESULTS: The questionnaire was returned by 306 clinicians. General practitioners and paediatric endocrinologists were more confident in management and were more likely to self-manage patients (p < 0.01). The oral contraceptive pill was the most frequently chosen first-line therapy by all clinicians, followed by transdermal oestrogen/progesterone, etonorgestrel implant, progesterone-only pills, levonorgestrel-intrauterine system and depot medroxyprogesterone acetate injections. General, community and subspecialist paediatricians were more likely to choose suboptimal management strategies for each of five clinical scenarios. CONCLUSIONS: Low confidence levels, suboptimal therapy choices and high referral rates are common among general paediatricians, community paediatricians and subspecialists for adolescents with menstrual and reproductive health concerns. Targeted education for these clinician groups, towards optimizing management for these patients, would enhance care.

Successful subcutaneous glucagon use for persistent hypoglycaemia in congenital hyperinsulinism.

Abstract Congenital hyperinsulinism (CHI) results from inappropriate excessive insulin secretion by the beta cells in the pancreas. A wide clinical spectrum of disease exists and a genetic diagnosis is now possible for approximately 50% of affected children. We describe a patient with atypical diffuse CHI caused by mosaic ABCC8 mutation inheritance, unmasked by paternal uniparental disomy. Hypoglycaemia persisted despite two subtotal pancreatectomies and trials of diazoxide and nifedipine were unsuccessful. Octreotide resulted in anaphylaxis, precluding its use. Continuous subcutaneous glucagon infusion was successful in restoring normoglycaemia and attenuating weight gain, with concomitant improvement of developmental milestones. No adverse effects have been encountered after >12 months of therapy. Administration problems (e.g., line crystallisation) may complicate continuous glucagon therapy; hence a practical description of infusion constitution is included. We recommend consideration of continuous subcutaneous glucagon infusion as a therapeutic option for persistent refractory hypoglycaemia in CHI.

Demographic and personal factors associated with metabolic control and self-care in youth with type 1 diabetes: a systematic review.

Optimal use of recent technological advances in insulin delivery and glucose monitoring remain limited by the impact of behaviour on self-care. In recent years, there has been a resurgence of interest in psychosocial methods of optimizing care in youth with type 1 diabetes. We therefore sought to examine the literature for demographic, interpersonal and intrapersonal correlates of self-care and/or metabolic control. Studies for this systematic review were obtained via an electronic search of Medline, Embase, Cumulative Index to Nursing and Allied Health Literature and PsycINFO databases. Seventy studies fulfilled the inclusion criteria. These studies have indicated that identifiable individual characteristics in each domain are robustly associated with metabolic control and/or self-care in children and adolescents. We present these characteristics and propose a theoretical model of their interactions and effect on diabetes outcomes. There is currently no consensus regarding patient selection for insulin pump therapy. In this era of scarce healthcare resources, it may be prudent to identify youth requiring increased psychosocial support prior to regimen intensification. The importance of this review lies in its potential to create a framework for rationally utilizing resources by stratifying costly therapeutic options to those who, in the first instance, will be most likely to benefit from them.

Overgrowth syndromes.

PURPOSE OF REVIEW: Human growth ensues from a complex interplay of physiological factors, in the wider setting of varying genetic traits and environmental influences. Intensive research in these divergent areas, and particularly in the field of genetics, continues to clarify the molecular basis of disorders which result in overgrowth, and it is therefore timely to provide a review of these findings. RECENT FINDINGS: This article provides an overview of the factors which regulate growth, followed by a discussion of the more commonly encountered overgrowth syndromes and their genetic basis as it is understood at the current time. There is also an added focus on recently discovered genetic associations in some conditions, such as Weaver, Perlman and Proteus syndromes. SUMMARY: New discoveries continue to be made regarding the genetic basis for many overgrowth syndromes and the development of a much needed molecular classification system for overgrowth may become possible as the interlinking functions of these genes on growth are unravelled. As there exists a wide spectrum of syndromes, disorders resulting in overgrowth can represent a diagnostic and therapeutic challenge, from those causing prenatal overgrowth with a poor prognosis to less severe genetic aberrations which are identified in later childhood or adult life.

Neonatal staphylococcal scalded skin syndrome: clinical and outbreak containment review.

Staphylococcal scalded skin syndrome (SSSS) is a toxin-mediated exfoliating skin condition predominated by desquamation and blistering. Neonatal outbreaks have already been reported; however, our outbreak highlights the potential for SSSS following neonatal health promotion measures such as intra-muscular vitamin K administration and metabolic screening (heel prick) as well as effective case containment measures and the value of staff screening. Between February and June 2007, five confirmed cases of neonatal SSSS were identified in full-term neonates born in an Irish regional maternity hospital. All infants were treated successfully. Analysis of contact and environmental screening was undertaken, including family members and healthcare workers. Molecular typing on isolates was carried out. An outbreak control team (OCT) was assembled and took successful prospective steps to prevent further cases. All five Staphylococcus aureus isolates tested positive for exfoliative toxin A, of which two distinct strains were identified on pulsed-field gel electrophoresis analysis. Two cases followed staphylococcal inoculation during preventive measures such as intra-muscular vitamin K administration and metabolic screening (heel prick). None of the neonatal isolates were methicillin resistant. Of 259 hospital staff (70% of staff) screened, 30% were colonised with S. aureus, and 6% were positive for MRSA carriage. This is the first reported outbreak of neonatal SSSS in Ireland. Effective case containment measures and clinical value of OCT is demonstrated. Results of staff screening underlines the need for vigilance and compliance in hand disinfection strategies in maternity hospitals especially during neonatal screening and preventive procedures.
