Observational Prospective Natural History of Patients with Sanfilippo Syndrome Type B
2017
To evaluate the natural course of disease progression in patients with Sanfilippo syndrome type B (mucopolysaccharidosis type IIIB), identify potential end points for future therapy trials, and characterize biomarkers related to the disease.A prospective, multicenter study was conducted. Baseline, 6-month, and 12-month assessments included neurodevelopmental status (Bayley Scales of Infant Development, Third edition), adaptive status (Vineland Adaptive Behavior Scales, Second Edition), volumetric brain magnetic resonance imaging, cerebrospinal fluid heparan sulfate, and urine glycosaminoglycan (GAG) measurements.Nineteen patients aged 1.6-31.7 years were enrolled. Over 12 months, cognition,…
Treatment response to dimethyl fumarate is characterized by disproportionate CD8+ T cell reduction in MS
2017
Background: The effect of dimethyl fumarate (DMF) on circulating lymphocyte subsets and their contribution as predictors of clinical efficacy have not yet been investigated in multiple sclerosis (MS). Objective: To evaluate lymphocytes and lymphocyte subsets (analyzed 6 months after DMF start) in MS patients with and without disease activity after 1 year of treatment in a retrospective study. Methods: Peripheral blood lymphocyte subsets were analyzed by flow cytometry. Untreated MS patients ( n = 40) were compared to those 6 months after onset of DMF treatment ( n = 51). Clinical and magnetic resonance imaging (MRI) disease activity of DMF-treated patients were assessed in the first year un…
Tracking of fruit, vegetables and unhealthy snacks consumption from childhood to adulthood (15 year period): does exposure to a free school fruit pro…
2019
Background The rationale for promoting increased consumption of fruit and vegetables (FV) at an early age is based on results from previous tracking-studies, indicating that dietary habits learned in childhood sustain into adulthood. Previous tracking studies have several limitations (e.g. low study sample, few repeated measurements and/or short a follow-up period). In addition, to our knowledge, no study has shown that a dietary intervention initiated in childhood affects tracking of dietary behaviour. The main objectives in this study were therefore to assess tracking of FV and unhealthy snacks in a large sample with multiple follow-up surveys over 15-years, and whether exposure to free s…
Vitamin D supplementation, bone turnover, and inflammation in HIV-infected patients
2018
IF 1.307 (2017); International audience; ObjectiveTo assess whether vitamin D supplementation could be associated with a modification of inflammatory markers and bone turnover in HIV-1-infected patients.Patients and methodsPatients who participated in an initial survey in 2010 and who were followed in the same department were included in a new study in 2012. Between 2010 and 2012, vitamin D supplementation was offered to patients presenting with hypovitaminosis D as per appropriate guidelines. Clinical examinations were performed, and fasting blood samples were taken for inflammation and bone marker evaluations.ResultsOf the 263 patients who participated in the 2010 study, 198 were included…
Baseline gut microbiome composition predicts metformin therapy short-term efficacy in newly diagnosed type 2 diabetes patients
2020
BackgroundThe study was conducted to investigate the effects of metformin treatment on the human gut microbiome's taxonomic and functional profile in the Latvian population, and to evaluate the correlation of these changes with therapeutic efficacy and tolerance.MethodsIn this longitudinal observational study, stool samples for shotgun metagenomic sequencing-based analysis were collected in two cohorts. The first cohort included 35 healthy nondiabetic individuals (metformin dose 2x850mg/day) at three time-points during metformin administration. The second cohort was composed of 50 newly-diagnosed type 2 diabetes patients (metformin dose-determined by an endocrinologist) at two concordant ti…
Predicting presenteeism via effort-reward imbalance and dispositional optimism: Is it the interaction that matters? Results from The Saxony Longitudi…
2019
BACKGROUND The importance of experienced work stress and individual traits as well as their interplay is analyzed with regard to dysfunctional coping behavior in case of sickness. OBJECTIVE The aim of this study was to examine the predictive capability of effort-reward imbalance (ERI) including overcommitment, meaning the intrinsic propensity in terms of excessive work-related expenditure (OC), in consideration of dispositional optimism/pessimism on presenteeism. METHODS A total of 353 men and women aged 38 from the 25th panel wave of The Saxony Longitudinal Study in 2011 were included in the analysis. Effort-reward imbalance (ERI) including overcommitment was assessed with the Effort-Rewar…
Smoking does not impact social and non-social cognition in patients with first episode psychosis.
2018
Abstract Background Many studies having shown significant improvements in non-social and social cognitive performance in smoking FEP patients compared to non-smoking FEP patients. The findings are controversial. This study analyzed the effects of tobacco use on non-social and social cognitive function in a large group of FEP patients and a matched healthy control group. Methods A sample of 335 patients with FEP and 253 healthy controls was divided into four subgroups: control tobacco users (CTU), control non-tobacco users (CNTU), patient tobacco users (PTU) and patient non-tobacco users (PNTU). Demographic variables, tobacco use variables (presence or absence, frequency and duration of toba…
Behavioral Precursors to Accidents and Resulting Physical Impairment
1995
The main goal of the study was to determine, within a model of emotional and behavioral regulation, if there are developmental precursors to accidents and resulting physical impairment. Data collected at ages 8 and 14 with 147 males and 142 females using peer nomination and teacher rating were related to the number of types of accidents the subjects had been in and impairment as a result of an accident by the age of 27 when the subjects were interviewed on their health. The results showed that 44% of the men and 14% of the women had been in an accident. Severe effects on health were obtained for 19% of the men and 5% of the women. Accidents and impairment were most frequent among individual…
Influential Periods in Longitudinal Clinical Cardiovascular Health Scores
2021
Abstract The prevalence of ideal cardiovascular health (CVH) among adults in the United States is low and decreases with age. Our objective was to identify specific age windows when the loss of CVH accelerates, to ascertain preventive opportunities for intervention. Data were pooled from 5 longitudinal cohorts (Project Heartbeat!, Cardiovascular Risk in Young Finns Study, The Bogalusa Heart Study, Coronary Artery Risk Development in Young Adults, Special Turku Coronary Risk Factor Intervention Project) from the United States and Finland from 1973 to 2012. Individuals with clinical CVH factors (i.e., body mass index, blood pressure, cholesterol, blood glucose) measured from ages 8 to 55 year…
Replication of fMRI group activations in the neuroimaging battery for the Mainz Resilience Project (MARP)
2020
Abstract Motivated by the recent replicability crisis we tested replicability of functional magnetic resonance imaging (fMRI) group activations in two independent samples. An identical behavioral and fMRI test battery for the longitudinal investigation of stress resilience mechanisms was developed for the Mainz Resilience Project (MARP) and conducted in a discovery (N = 54) and a replication sample (N = 103). The test battery consisted of a stress reactivity task, a reward sensitivity task, a fear conditioning and extinction paradigm, two volitional reappraisal tasks and an emotional interference inhibition task. Replicability of group activations was tested with the Jaccard index and the I…
