Vitamin D and Health Outcomes in Preterm Born Population
Vitamin D3 DeficiencyPrematurity5 moreImproved survival of very preterm newborn population during the last decades has challenged us neonatologists to study and improve nutritional practices including vitamin D (VitD) supplementation. However, long term outcome in this aspect has not been researched in well documented preterm populations. As VitD has receptors in almost all human cells it modulates growth of many organs. Therefore I start to assess VitD supplementation practices and later health outcome (bones, teeth, muscles, heart, lungs) in two preterm population cohorts cared in Oulu University Hospital at the age of 5 years and 24 years (born 2014-2017 and 1994-1997).
Glucose Variability and Cognition in Prediabetes
Glucose Metabolism Disorders (Including Diabetes Mellitus)Cognitive Decline4 moreThis study examines the association of variability in glucose values over a 10-day period with cognitive function and functional status among individuals with prediabetes, aged 50 or older.
Signature of the Risk Profile of Mortality in a Hospital Cohort of Patients With Metabolic Diseases...
Metabolic DiseaseEpidemiological studies are usually conducted in the general population in adults without complications or pathology at baseline. The results obtained are therefore often better designed for primary prevention use. The prediction of mortality risk in patients with complications and requiring hospital follow-up is less well known. The study purpose is to determine a mortality risk profile in a hospital cohort of patients with pathologies associated with metabolic diseases. Today the "multimaker" scores based on a panel of biomarkers - have significantly improved the discriminating power of prediction models existing in many pathologies. It is no longer a single biomarker that can improve risk prediction but a complete and cross-sectional profile that is sought after. We aim to establish a personalised mortality risk profile by combining clinical and biological parameters including metabolomics, genetics, transcriptomics and epigenomics by high throughput screening of biological samples.
HIV Exposure In Utero and Metabolic Disease Risk in HIV-Negative Young Adults
HIV-exposed UninfectedGlobally, over 1 million babies are born to mothers with HIV each year. With the advent of prenatal antiretroviral therapy, up to 98% of these individuals may be HIV-exposed uninfected (HEU). A growing literature suggests that in utero HIV exposure - even in the absence of subsequent infection - may be associated with adverse health outcomes in infancy and childhood. However, there is little information about the long-term health implications of in utero HIV exposure later in life, such as into adulthood. In this study, for the first time, we seek to prospectively evaluate metabolic and immune indices among HEU young adults as compared to well-matched HIV-unexposed uninfected controls. This study serves as a necessary first step toward optimizing clinical care for this expanding and aging HEU population, including the implementation of novel screening and prevention strategies.
Understanding Metabolism and Inflammation Risks for Diabetes in Adolescents
Type 2 DiabetesInsulin Resistance3 moreThis research study collects health-related information and blood samples to better understand how body composition, lifestyle habits, and diet influence meta-inflammatory monocytes (MiMos) in adolescents. The hypothesis of this study is that adolescents at risk for metabolic disease have enhanced MiMo related activities leading to insulin resistance.
Identification and Characterization of Novel Non-Coding Variants That Contribute to Genetic Disorders...
Genetic DiseaseInborn Errors of Metabolism3 moreThe goal of this study is to identify and characterize novel non-coding and splicing variants that may contribute to genetic disorders. We will particularly focus on patients with a diagnosed genetic disorder that has inconclusive genetic findings.
Metabolic and Infectious Diseases in La Réunion (the REUNION Population-based Study)
Infectious DiseaseCardiovascular Diseases2 moreThe aim of the present study is to determine the prevalence of cardiometabolic and infectious disease in La Reunion (french oversea department and region of France). Known or suspected risk factor for these diseases will also be assessed, such as microbiota, cognitive impairement, social inequalities, and genetics.
Hormonal and Inflammatory Changes During Pregnancy in Women With Glucose Metabolic Disorders.
Diabetes MellitusType 27 moreThe first aim of this study is to describe maternal hormonal and inflammatory changes during pregnancy in women that differ metabolically (limited to women with type 2 diabetes, gestational diabetes and/or overweight). The second aim of this study is to examine maternal hormonal, inflammatory and metabolic factors associated with insulin sensitivity in human pregnancy.
Imaging Biomarkers in Obesity
Alzheimer DiseaseObesity1 moreHigh body fat at midlife, as evidenced by overweight or obese body mass index (BMI), is increasingly understood as a risk factor for Alzheimer's disease. However, the underlying processes and mechanisms that may underlie this risk remains unknown. With this project, the Investigator proposes to create a new cohort of cognitively normal 120 midlife individuals, age 40-60 years. The investigator and research staff will characterize the participant's overweight or obese status using metabolic tests including, an oral glucose tolerance test, fasting plasma insulin, fasting plasma glucose, and hemoglobin A1c measurements. This testing will generate categories of metabolically abnormal overweight and obese (MAOO), metabolically normal overweight and obese (MNOO), and metabolically normal lean participants (MNLP). Research staff will evaluate differences between these groups on neuroimaging with the newer classification framework of Alzheimer's biomarkers with amyloid (A), tau (T), and neurodegeneration (N), or ATN. Neurodegeneration will be assessed by atrophy on brain MRI as reflected by regional volumes on Freesurfer. Staff will also evaluate MR neuroimaging markers for neuroinflammation using a newer method called diffusion basis spectrum imaging (DBSI), developed at the Mallinckrodt Institute of Radiology at Washington University in St. Louis in collaboration with The Charles F. and Joanne Knight Alzheimer's Disease Research Center (Knight ADRC).
Longitudinal Study of Ultra-rare Inherited Metabolic and Degenerative Neurological Diseases.
Inherited DiseaseRare Diseases4 moreGeneral aim of the study is the improvement of the clinical knowledge of ultra-rare inherited metabolic and degenerative neurological diseases (prevalence less than 5:100,000) in adulthood through the systematic longitudinal collection of clinical, laboratory and instrumental data.
