Aims: Socioeconomic problems may present significant challenges when trying to reach optimal glycaemic control in paediatric patients with type 1 diabetes. We examined sociodemographic factors affecting metabolic control in patients in one of the biggest paediatric diabetes clinics in Finland.
Methods: One hundred ninety-one children (age 2-15 years; median 11 years; 47% female) with type 1 diabetes and their families were recruited during outpatient visits in the paediatric diabetes clinic of Tampere University Hospital, Finland.
Purpose: Second-generation antipsychotic medications (SGAs) are widely used in child psychiatry. SGA-induced metabolic disturbances are common in children, but monitoring practices need systematisation. The study's aims were to test an SGA-monitoring protocol, examine the distributions of metabolic measurements compared to reference values in child psychiatry patients, and determine whether using a homeostasis model for the assessment of insulin resistance (HOMA-IR) and triglyceride/high-density lipoprotein (TG/HDL) ratio could improve the detection of increased cardiometabolic risk.

Methods: This was a multinational, non-interventional study surveying 17 physicians from 11 countries. Each physician was asked to provide insulin dose adjustments for the settings of the pump including basal rate, carbohydrate-to-insulin ratios (CRs), and correction factors (CFs) for 15 data sets of pumps and SMBG of people with T1D (mean age 18.
Objective: The aim of this study was to explore the extended family history of type 1 diabetes in children at genetic risk and define the impact of a positive family history on the development of islet autoimmunity and type 1 diabetes.
Methods: The subjects were participants in The Finnish Type 1 Diabetes Prediction and Prevention (DIPP) study and carried increased HLA-conferred risk for type 1 diabetes. The case children (N = 343) were positive for at least one islet autoantibody, and the control children (N = 343) matched by age, gender and class II HLA genotype were negative for islet autoantibodies at the time of data collection.
Aim: This study examined the use and adverse reactions of second-generation antipsychotics (SGAs), alone or combined with other psychotropic medication, to identify areas for standardising prescribing and monitoring practices.
Methods: We conducted a retrospective study at Tampere University Hospital, Finland, involving 128 patients (81% boys) who were under 13 years old at SGA initiation and had SGA treatment between October 2013 and October 2014.
Results: The median age at baseline was 9.
Background: Obesity in childhood appears often during the toddler years. The prenatal environment influences obesity risk. Maternal gestational diabetes, the child's diet, and physical activity in the first few years have an important role in subsequent weight gain.

Objective: The objective of the study was to characterize different forms of diabetes diagnosed during the first year of life.
Design: Patients diagnosed with diabetes before the age of 1 year in 10 Finnish hospitals from 1980 to 2014 were included.
Congenital disorders of glycosylation (CDG) are a relatively recently identified group of multisystem disorders caused by defective glycosylation of N-glycosylated proteins. They mainly involve the central and peripheral nervous system, but other organ systems are involved as well. Type CDG Ia accounts for over 80% of cases, characterized by decreased activity of the enzyme phosphomannomutase caused by mutations in chromosome 16 PMM2 gene.

The aim of this study was to evaluate the clinical course of LCHADD with the homozygous 1528G>C (E510Q) mutation when patients underwent strict dietary treatment.
Methods: From 1997 to 2010, 16 patients with LCHADD were diagnosed in Finland.
Patients with type 1 diabetes have an average of two symptomatic hypoglycemias in a week and at least one severe hypoglycemia in a year. The most common causes of hypoglycemia are overcorrection of hyperglycemia, excessive basal insulin dose, and physical exercise. Fear of hypoglycemia is common and leads to poor control of diabetes.

The current study evaluates the association between specific EV subtypes and type 1 diabetes by measuring type-specific antibodies against the group B coxsackieviruses (CVBs), which have been linked to diabetes in previous surveys. Altogether, 249 children with newly diagnosed type 1 diabetes and 249 control children matched according to sampling time, sex, age, and country were recruited in Finland, Sweden, England, France, and Greece between 2001 and 2005 (mean age 9 years; 55% male).

The predictive values of these markers and their relation to other risk factors of T1D were assessed in children with advanced β-cell autoimmunity, i.e.

Even the prenatal environment may expose a child to unhealthy weight gain; maternal gestational diabetes is known to be among the prenatal risk factors conducive to obesity. Here we report the effects of antenatal dietary and physical activity counselling on pregnancy and infant weight gain outcomes.
View Article and Find Full Text PDFBackground: Prevention is considered effective in combating the obesity epidemic. Prenatal environment may increase offspring's risk for obesity. A child starts to adopt food preferences and other behavioral habits affecting weight gain during preschool years.
View Article and Find Full Text PDFAim: The study aimed to assess the effects of diabetes-related risk factors, especially severe hypoglycaemia,on the academic skills of children with early-onset type 1 diabetes mellitus (T1DM).
Method: The study comprised 63 children with T1DM (31 females, 32 males; mean age 9 y 11 mo,SD 4 mo) and 92 comparison children without diabetes (40 females, 52 males;mean age 9 y 9 mo,SD 3 mo). Children were included if T1DM had been diagnosed before the age of 5 years and if they were aged between 9 and 10 years at the time of study.
Background: Fetal conditions are known to be partly responsible for the child's risk for obesity. Our pilot study aimed to determine the effect of gestational lifestyle counseling on the offspring weight gain until 4 years of age and to estimate power for future studies.
Design And Methods: First-time pregnant mothers participated in a controlled trial conducted in maternity health clinics during 2004 - 2006.
Objective: To investigate the effect of intensified lifestyle counselling targeting infants' mothers on offspring weight development during the first 4 years of life.
Design And Setting: Follow-up of a cluster-randomised controlled trial in primary care child health clinics during 2004-2006 in Finland. Participants received a follow-up survey during 2010 concerning weight and height measurements of their offspring.
Background: The 65-kD isoform of glutamic acid decarboxylase (GAD65) is a major autoantigen in type 1 diabetes. We hypothesized that alum-formulated GAD65 (GAD-alum) can preserve beta-cell function in patients with recent-onset type 1 diabetes.
Methods: We studied 334 patients, 10 to 20 years of age, with type 1 diabetes, fasting C-peptide levels of more than 0.
Insulin-induced lipoatrophy is a rare but serious complication of insulin treatment. Its incidence decreased during 1970' and 1980's, but several reports of this phenomenon have again recently been published. Traditional treatment options have included injecting insulin or pump cannula to the area surrounding the lipoatrophy or changing the insulin type or preparation.

Inadequate function of these enzymes may in worst cases lead to hyperammonemic encephalopathy and death. The danger of urea cycle enzyme deficiencies is that previously healthy adults with no prior medical history suggesting these deficiencies may suddenly develop life-threatening complications during prolonged catabolic situations such as delivery or surgery.

We investigated changes in the serum metabolome prospectively in children who later progressed to type 1 diabetes. Serum metabolite profiles were compared between sample series drawn from 56 children who progressed to type 1 diabetes and 73 controls who remained nondiabetic and permanently autoantibody negative.
