Predictors of microvascular complications in type 1 diabetic patients at onset: The role of metabolic memory
2011
Background Several epidemiological studies showed a close association between metabolic control and microvascular complications in type 1 Diabetes Mellitus (T1DM). The aim of our longitudinal observational study was to evaluate the predictive role of the main clinical and biochemical parameters in determining microvascular complications. Methods 376 T1DM patients, hospitalized in our division from 1991 to 2005 (mean follow-up = 10.93 ± 4.26 years) were studied. Stepwise Cox regression analysis was used to identify the influence of residual ß-cell function, ß-cell autoimmunity, HbA1c levels and other clinical and laboratory parameters in the development of microalbuminuria and retinopathy.

Advanced interatrial block predicts new-onset atrial fibrillation and ischemic stroke in patients with heart failure: The “Bayes' Syndrome-HF” study
2018
Advanced interatrial block (IAB) is characterized by a prolonged (≥120 ms) and bimodal P wave in the inferior leads. The association between advanced IAB and atrial fibrillation (AF) is known as “Bayes' Syndrome”, and there is scarce information about it in heart failure (HF). We examined the prevalence of IAB and whether advanced IAB could predict new-onset AF and/or stroke in HF patients. Methods and results: The prospective observational “Bayes' Syndrome-HF” study included consecutive outpatients with chronic HF. The primary endpoints were new-onset AF, ischemic stroke, and the composite of both. A secondary endpoint included all-cause death alone or in combination with the primary endpo…
Comparing Subjective With Objective Sleep Parameters Via Multisensory Actigraphy in German Physical Education Students.
2015
This study compared subjective with objective sleep parameters among 72 physical education students. Furthermore, the study determined whether 24-hr recording differs from nighttime recording only. Participants wore the SenseWear Armband™ for three consecutive nights and kept a sleep log. Agreement rates ranged from moderate to low for sleep onset latency (ICC = 0.39 to 0.70) and wake after sleep onset (ICC = 0.22 to 0.59), while time in bed (ICC = 0.93 to 0.95) and total sleep time (ICC = 0.90 to 0.92) revealed strong agreement during this period. Comparing deviations between 24-hr wearing time (n = 24) and night-only application (n = 20) revealed no statistical difference (p > 0.05). As a…
Dopamine-related genes and spontaneous smoking cessation in ever-heavy smokers
2011
Several studies have provided evidence for associations of polymorphisms located in and near dopamine-related genes and nicotine dependence and other smoking-related phenotypes, including pharmacogenetic interactions. Aim: The purpose of the present work was to examine the association of SNPs in the DOPA decarboxylase (DDC), dopamine receptor D2 (DRD2) and dopamine transporter (SLC6A3) genes with smoking cessation in a large retrospective study featuring approximately 900 cessation events. Materials & methods: Data originated from the enrollment questionnaire of the epidemiological ESTHER study of community-dwelling adults aged 50–74 years, conducted in the German state of Saarland bet…
Late-onset myasthenia gravis - CTLA4(low) genotype association and low-for-age thymic output of naïve T cells.
2014
Abstract Late-onset myasthenia gravis (LOMG) has become the largest MG subgroup, but the underlying pathogenetic mechanisms remain mysterious. Among the few etiological clues are the almost unique serologic parallels between LOMG and thymoma-associated MG (TAMG), notably autoantibodies against acetylcholine receptors, titin, ryanodine receptor, type I interferons or IL-12. This is why we checked LOMG patients for two further peculiar features of TAMG – its associations with the CTLA4 high/gain-of-function +49A/A genotype and with increased thymic export of naive T cells into the blood, possibly after defective negative selection in AIRE-deficient thymomas. We analyzed genomic DNA from 116 …
Early-onset depressive disorders predict the use of addictive substances in adolescence: a prospective study of adolescent Finnish twins
2008
Aims To explore the developmental relationships between early-onset depressive disorders and later use of addictive substances. Design, setting and participants A sample of 1545 adolescent twins was drawn from a prospective, longitudinal study of Finnish adolescent twins with baseline assessments at age 14 years and follow-up at age 17.5 years. Measurements At baseline, DSM-IV diagnoses were assessed with a professionally administered adolescent version of Semi-Structured Assessment for Genetics of Alcoholism (C-SSAGA-A). At follow-up, substance use outcomes were assessed via self-reported questionnaire. Findings Early-onset depressive disorders predicted daily smoking [odds ratio (OR) …
Late onset administration of oral antioxidants prevents age-related loss of motor co-ordination and brain mitochondrial DNA damage.
1999
We have studied the effect of aging on brain glutathione redox ratio, on brain mitochondrial DNA damage and on motor co-ordination in mice and the possible protective role of late onset administration of sulphur-containing antioxidants. Glutathione redox ratios change to a more oxidized state in whole brain with aging but the changes are much more pronounced when this ratio is measured in brain mitochondria. The levels of 8-oxo-7,8-dihydro-2 '-deoxyguanosine in mitochondrial DNA are much higher in the brain of old animals than in those of young ones. Late onset oral administration of sulphur-containing antioxidants partially prevents oxidation of mitochondrial glutathione and DNA. There is …
Psychological distress of children with early-onset type 1 diabetes and their mothers' well-being
2015
Aim Few studies have focused on the psychological adjustment of pre-adolescent children with type 1 diabetes. This study examined psychosocial functioning in nine- and 10-year-old children with early-onset type 1 diabetes, and their mothers, and associations between psychosocial functioning and diabetes management. Methods The mothers of 63 children with early-onset diabetes and 86 healthy children evaluated their own psychosocial functioning, and their child's, with standardised rating scales. We used general linear models to analyse the children's behaviour problems and the mothers' well-being. Associations between the children's behaviour problems, diabetes-related measures and the mothe…
Remission phase in children diagnosed with type 1 diabetes in years 2012 to 2013 in Silesia, Poland: An observational study
2018
Background/objective The study aimed to analyze the frequency of partial remission (PR) and its association with chosen clinical and laboratory factors among pediatric patients with newly diagnosed type 1 diabetes (T1D). The long-term effect of PR on chosen parameters was also investigated. Methods In 194 patients (95 girls) aged 8.1 ± 4.3 years, we analyzed data at T1D onset: glycemia, pH, C-peptide, antibodies, weight, and concomitant autoimmune diseases. Anthropometric parameters, daily insulin requirement (DIR), and HbA1c 2 and 4 years after T1D diagnosis were also analyzed. We determined PR based on HbA1c and DIR measurements at least every 3 months. Results PR occurred in 59% of patie…
The parkin gene is not a major susceptibility locus for typical late-onset Parkinson's disease
2001
We investigated the parkin gene in 118 patients with typical Parkinson's disease (PD), i. e. in patients who had an onset of PD after the age of 45 years. The study group included 95 subjects with sporadic PD and 23 subjects from 18 families with autosomal recessive PD. No pathogenetic mutations in the parkin gene were detected either in familial or in sporadic patients. Our findings indicate that the parkin gene is not involved in the pathogenesis of classic late-onset PD.
