RESUMO
OBJECTIVE: Screening for depression, diabetes distress, and disordered eating in youth with type 1 diabetes (T1D) is recommended, as these comorbidities contribute to poor glycemic control. No consensus exists on which measures are optimal, and most previous studies have used nondisease-specific measures. We examined the utility of screening for these disorders using two disease-specific and one general measure at the time of transition from pediatric to adult care. METHODS: Forty-three young adults from a T1D transition clinic completed the Patient Health Questionnaire, the Diabetes Distress Scale, and the Diabetes Eating Problem Survey-Revised. Chart review determined if clinicians noted similar symptoms during the year prior to transition. Metabolic data were also recorded. RESULTS: Chart review identified 5 patients with depressive symptoms and 8 patients with diabetes distress. Screening identified 2 additional patients with depressive symptoms and 1 additional patient with diabetes distress. Of those noted to have symptomatic depression or diabetes distress on chart review, several subsequently screened negative on transition. Disordered eating was not detected by chart review, but 23.5% screened positive on transition. While depression, diabetes distress, and disordered eating positively correlated with glycated hemoglobin (HbA1c) (r = 0.31, P = .05; r = 0.40, P = .009; r = 0.63, P<.001, respectively), disordered eating accounted for the majority of observed variance (df = 1; F = 18.6; P<.001). Even though HbA1c was higher in patients with versus without disordered eating (P<.001), body mass index did not differ between the 2 groups (P = .51). CONCLUSION: In young adults with T1D, formal screening provides an opportunity to detect psychological problems, which, when treated, may help optimize metabolic control during the transition process.

Type 1 diabetes is the most commonly seen endocrinopathy in pediatrics. This is an autoimmune condition. Children with type 1 diabetes are at much greater risk for other autoimmune conditions, particularly autoimmune thyroiditis, most commonly Hashimoto's thyroiditis, and celiac disease. It is important for the primary care practitioner to be aware of subtle symptoms of these conditions and how to screen for them because early treatment of both conditions can lead to better diabetes control and improved health in general.

Although there are many etiologies for delayed puberty in adolescent-aged girls, the pediatric provider should consider primary ovarian insufficiency if estradiol remains undetectable despite elevated levels of gonadotropins. Adolescent girls with this diagnosis will need holistic care from their primary care provider, focusing on both their medical and psychosocial needs. The following case study describes a 14-year-old girl who was referred to pediatric endocrinology for delayed puberty, in the setting of increased gonadotropins and undetectable estradiol. The differential diagnosis, evaluation, and management of primary ovarian insufficiency are reviewed as well as potential long-term health considerations.

Children with autism spectrum disorder (ASD) face many challenges, including feeding problems due to behavioral issues and food aversions. Therefore, pediatric nurse practitioners need to assess for different mineral deficiencies, including iron deficiency anemia (IDA). The following case study describes a 4-year-old with ASD with persistent IDA despite typical recommendation of oral iron supplementation. Other potential etiologies of IDA are reviewed. Finally, different management approaches for managing IDA in children with ASD are described.

INTRODUCTION: Emerging adults (EA) with disordered eating behaviors (DEBs) and Type 1 diabetes (T1D) are at increased risk for severe complications of T1D, and these behaviors have been reported in EA women with T1D. Few studies, though, have included men. This study assessed the prevalence of DEB in both EA men and women with T1D. METHODS: DEB was measured with the diabetes-specific Diabetes Eating Problem Survey-Revised (DEPS-R); scores of 20 or greater indicate need for further evaluation for DEB. RESULTS: A total of 27 women and 33 men (age range = 21 ± 2.5 years) completed the DEPS-R; 27% of women and 18% of men had scores of 20 or greater (p = .23). Hemoglobin A1c level was significantly higher in subjects with elevated DEPS-R scores (10.4 ± 2.1% vs. 7.8 ± 1.3%; p < .001), and DEPS-R scores correlated with increased body mass index values (r = 0.27, p < .05). DISCUSSION: Clinicians should assess for DEB in both male and female emerging adults with T1D, especially overweight patients with poor glycemic control.

Type 1 diabetes mellitus was thought to be the prevalent type of diabetes in children and adolescents; however, increasing numbers of juvenile patients appear to have type 2 diabetes. Management of all diabetes in young patients should include regular assessment, careful monitoring for glycemic control and the presence of hypoglycemia, and educational training on disease management. Hypoglycemic episodes, especially nocturnal events, are frequent in the young diabetic patient. Improvements in glycemic control and nocturnal hypoglycemia have been observed with continuous subcutaneous insulin infusion and insulin glargine. A continuous glucose-monitoring system can provide important insight into 24-hour glycemic control. Overall, careful management, monitoring, and education can improve glycemic control and yield positive treatment outcomes in the child or adolescent with diabetes.

OBJECTIVE: The efficacy of the insulin analogs now available for multiple daily injection (MDI) and continuous subcutaneous insulin infusion (CSII) therapy in type 1 diabetes has not yet been established in pediatric patients. Our principal aim in this short-term study was to compare the efficacy of CSII to MDI with glargine in lowering HbA(1c) levels in children and adolescents with type 1 diabetes. RESEARCH DESIGN AND METHODS: Thirty-two youth with type 1 diabetes (age 8-21 years) were randomly assigned to receive either MDI treatment with once-daily glargine and premeal/snack insulin aspart or CSII with insulin aspart. Dose titration in both groups was based on home self-monitored blood glucose measurements and monthly HbA(1c). HbA(1c), total daily insulin dose (TDD), self-monitored blood glucose readings, and adverse events were compared after 16 weeks of therapy. RESULTS: While there was no significant change in the glargine group (HbA(1c) 8.2% at baseline vs. 8.1% at 16 weeks), youth randomized to CSII had a sharp reduction in HbA(1c) levels, from 8.1 to 7.2% after 16 weeks of therapy (P < 0.02 vs. baseline and <0.05 vs. glargine group). TDD was unchanged in the glargine group, but significantly dropped with CSII (1.4 units/kg at baseline vs. 0.9 units/kg at 16 weeks, P < 0.01). Both groups had similar basal doses and insulin-to-carbohydrate ratios. Fasting self-monitored blood glucose was similar in both groups, but lunch, dinner, and bedtime readings were significantly lower in the CSII group (P < 0.01). CONCLUSIONS: Lower HbA(1c) and premeal glucose levels were more achievable in this short-term study with CSII than with glargine-based MDI treatment. CSII is an efficacious treatment to improve metabolic control in youth with type 1 diabetes.

Root-knot nematodes (Meloidogynejavanica) are obligate sedentary endoparasites that must penetrate the host root to initiate their life cycle. Many enzymes are secreted by the nematode to facilitate host penetration; required enzymes may include pectate lyases and cellulases. Using differential screening, a class III pectate lyase, Mj-pel-1 (M. javanica pectate lyase 1), was cloned from a library enriched for esophageal gland genes. DNA gel blotting confirmed that the Mj-pel-1 gene was of nematode origin and a member of a small multigene family. In situ hybridization localized the expression of Mj-pel-1 to the basal cells of the esophageal glands, while immunolocalization detected the protein in the esophageal glands as well as on the exterior of the nematode, confirming that the protein is secreted. When MJ-PEL-1 was expressed in Pichia pastoris, the resulting protein was active. The pH optimum of MJ-PEL-1 was 10.0, and the enzyme was five times more active on pectate than on pectin. Like other class III pectate lyases, MJ-PEL-1 also displayed an absolute requirement for Ca2+. The root-knot nematode migrates through the middle lamella of the plant root; therefore, MJ-PEL-1 may be an important enzyme early in the infection process.

Root-knot nematodes are obligate plant parasites that alter plant cell growth and development by inducing the formation of giant cells for feeding. Nematodes inject secretions from their esophageal glands through their stylet and into plant cells to induce giant cell formation. Meloidogyne javanica chorismate mutase 1 (MjCM-1) is one such esophageal gland protein likely to be secreted from the nematode as giant cells form. MjCM-1 has two domains, an N-terminal chorismate mutase (CM) domain and a C-terminal region of unknown function. It is the N-terminal CM domain of the protein that is the predominant form produced in root-knot nematodes. Transgenic expression of MjCM-1 in soybean hairy roots results in a phenotype of reduced and aborted lateral roots. Histological studies demonstrate the absence of vascular tissue in hairy roots expressing MjCM-1. The phenotype of MjCM-1 expressed at low levels can be rescued by the addition of indole-3-acetic acid (IAA), indicating MjCM-1 overexpression reduces IAA biosynthesis. We propose MjCM-1 lowers IAA by causing a competition for chorismate, resulting in an alteration of chorismate-derived metabolites and, ultimately, in plant cell development. Therefore, we hypothesize that MjCM-1 is involved in allowing nematodes to establish a parasitic relationship with the host plant.

Leaves are reported to contain a secreted alpha-amylase that accumulates during senescence or after biotic or abiotic stress; however, a gene encoding this enzyme has not been described. Because a secreted amylase is isolated from plastidic starch, the function of this enzyme is difficult to predict, but circumstantial evidence suggests that it may degrade starch after cell death. The Arabidopsis thaliana genome contains three alpha-amylase genes, one of which, AMY1 (At4g25000), has a putative signal sequence suggesting that the protein may be secreted. Two independent T-DNA insertion mutants in AMY1 lacked an amylase band on starch zymograms, which was previously named 'A1'. Washed leaf protoplasts contained reduced A1 activity suggesting that the enzyme is secreted. Native AMY1, fused to a weakly fluorescent form of GFP, was sensitive to proteinase K infiltrated into leaf apoplastic spaces, while a cytosolic form of GFP was unaffected until cell breakage, confirming that the AMY1 protein is secreted. Amylase A1 was transcriptionally induced in senescing leaves and in leaves exposed to heat stress, treated with abscisic acid or infected with Pseudomonas syringae pv. tomato expressing avrRpm1. The A1 amylase was also extremely heat resistant and its expression was up-regulated in cpr5-2, an activated defence response mutant.

OBJECTIVE: Use of continuous subcutaneous insulin infusion (CSII) has increased dramatically in recent years, and pump therapy has been shown to be a safe and effective alternative to multiple daily injections in adults and older pediatric patients with type 1 diabetes. Its use in very young children, however, has been limited, although this group might be expected to benefit the most from CSII. The objective of this study was to analyze the CSII efficacy and safety data in very young children with type 1 diabetes from our Diabetes Clinic database. METHODS: Glycosylated hemoglobin (HbA1c), severe hypoglycemia (SH), and ketoacidosis (DKA) in the year before CSII were compared with corresponding values during pump treatment in all children who started CSII before age 7. RESULTS: Sixty-five children (mean age: 4.5 y at CSII initiation; range: 1.4-6.9 years; 28 girls; 3 black, 1 Hispanic) were analyzed for >162 patient-years of follow-up. Mean HbA(1c) (7.4 +/- 1.0 prepump) decreased to 7.0 +/- 0.9 after 12 months of CSII and continued to improve even after 4 years on CSII. The rate of SH was reduced by 53% (from 78 to 37/100 patient-years). Children who received daytime care from paid caregivers (n = 26) experienced significant reductions in HbA1c and hypoglycemia frequency. There were no episodes of DKA requiring emergency treatment in the year before CSII and 4 episodes (4 per 100 patient-years) after transition to pump. CONCLUSIONS: CSII is a durable and effective means of optimizing glycemic control in very young patients with type 1 diabetes and may be superior to multiple daily injections in minimizing the risk of severe hypoglycemia in this age group. Employment of paid caregivers does not preclude safe and effective use of CSII.
