1  646 139 BIRTH MODE AND INFECTIOUS MORBIDITY RISKS IN QOM CHILDREN OF ARGENTINA. OBJECTIVES: CESAREAN DELIVERY MAY INCREASE CHILDHOOD INFECTIOUS MORBIDITY RISKS VIA ALTERED BIRTH EXPOSURES AND SUBSEQUENT IMMUNE, MICROBIAL, AND EPIGENETIC DEVELOPMENT. MANY LATIN AMERICAN INDIGENOUS POPULATIONS EXPERIENCE DUAL BURDENS OF INFECTIOUS AND CHRONIC DISEASES, AND ARE PARTICULARLY VULNERABLE TO RISING RATES OF CESAREAN DELIVERY AND ASSOCIATED ADVERSE OUTCOMES. THE QOM/TOBA ARE AN INDIGENOUS POPULATION IN ARGENTINA EXPERIENCING RAPID LIFESTYLE TRANSITIONS. WE HYPOTHESIZED THAT CESAREAN DELIVERY WOULD BE ASSOCIATED WITH INCREASED RISK OF INFECTIOUS SYMPTOMS IN QOM CHILDREN AFTER ADJUSTING FOR GESTATIONAL AND NUTRITIONAL FACTORS. METHODS: WE CONDUCTED A SECONDARY ANALYSIS OF BIRTH RECORDS AND MONTHLY ANTHROPOMETRIC AND ILLNESS DATA COLLECTED PREVIOUSLY FROM 90 QOM CHILDREN (AGED 1-55 MONTHS). WE TESTED FOR ADDITIVE EFFECTS OF BIRTH MODE ON RISK OF GASTROINTESTINAL (GI) AND RESPIRATORY ILLNESS (RI) IN MIXED-EFFECTS LOGISTIC REGRESSION MODELS ADJUSTING FOR CHILD WEIGHT-FOR-AGE (WAZ), WEANING, AND GESTATIONAL AND MATERNAL AGE. RESULTS: CESAREAN DELIVERIES ACCOUNTED FOR 46% OF BIRTHS AND WERE ASSOCIATED WITH MATERNAL AGE < 20 AND >/= 30 YEARS, GESTATIONAL AGE < 39 WEEKS, AND PRENATAL COMPLICATIONS. GI AND RI RISKS WERE REDUCED IN ASSOCIATION WITH CESAREAN DELIVERY, GREATER WAZ, WEANING, MATERNAL AGE >/= 30 YEARS, AND GESTATIONAL AGE < 39 WEEKS. CONCLUSIONS: THE RELATIONSHIP BETWEEN CESAREAN DELIVERY AND REDUCED INFECTIOUS RISKS MAY REFLECT STATISTICAL CONFOUNDING WITH RELATIVELY RAPID POSTNATAL GROWTH AND GREATER ADIPOSITY. POSTNATAL GROWTH TRAJECTORIES MAY BE IMPORTANT MEDIATORS OF LONG-TERM MORBIDITY RISKS ASSOCIATED WITH CESAREAN DELIVERY. THE FREQUENCY OF CESAREAN DELIVERIES AMONG THE QOM REMAINS CONCERNING GIVEN TRADITIONALLY HIGH RATES OF FERTILITY AND ADOLESCENT PREGNANCY.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
2 1095  41 COHORT PROFILE: THE EWHA BIRTH AND GROWTH STUDY. WITH THE INTRODUCTION OF LIFE-COURSE EPIDEMIOLOGY, RESEARCHERS REALIZED THE IMPORTANCE OF IDENTIFYING RISK FACTORS IN EARLY LIFE TO PREVENT CHRONIC DISEASES. THIS LED TO THE ESTABLISHMENT OF THE EWHA BIRTH AND GROWTH STUDY IN 2001; THE STUDY IS A PROSPECTIVE BIRTH COHORT DESIGNED TO PROVIDE EVIDENCE OF EARLY LIFE RISK FACTORS FOR A CHILD'S GROWTH AND HEALTH. PARTICIPANTS WERE RECRUITED FROM THOSE WHO VISITED EWHA WOMANS UNIVERSITY MOKDONG HOSPITAL (A TERTIARY HOSPITAL IN SOUTHWEST SEOUL, KOREA) FOR PRENATAL CARE AT 24-28 WEEKS OF GESTATION. IN TOTAL, 891 MOTHERS ENROLLED IN THIS STUDY BETWEEN 2001 AND 2006 AND THEIR OFFSPRING (N=940) WERE FOLLOWED-UP. REGULAR CHECK-UP EXAMINATIONS OF OFFSPRING WERE CONDUCTED AT 3 YEARS, 5 YEARS, AND 7 YEARS OF AGE AND EVERY YEAR THEREAFTER. TO CONSIDER AGE-RELATED HEALTH ISSUES, EXTENSIVE DATA WERE COLLECTED USING QUESTIONNAIRES AND MEASUREMENTS. IN 2021, THE STUDY SUBJECTS WILL REACH 19 YEARS OF AGE, AND WE ARE PLANNING A CHECK-UP EXAMINATION FOR EARLY ADULTHOOD. ABOUT 20 YEARS HAVE PASSED SINCE THE COHORT DATA WERE COLLECTED, AND WE HAVE PUBLISHED RESULTS ON CHILDHOOD HEALTH OUTCOMES ASSOCIATED WITH PRENATAL AND BIRTH CHARACTERISTICS, GENETIC AND EPIGENETIC CHARACTERISTICS RELATED TO CHILDHOOD METABOLISM, THE EFFECTS OF EXPOSURE TO ENDOCRINE DISRUPTORS, AND DIETARY PATTERNS IN CHILDHOOD. RECENTLY, WE STARTED REPORTING ON TOPICS RELATED TO ADOLESCENT HEALTH. THE FINDINGS WILL FACILITATE IDENTIFICATION OF EARLY LIFE RISK FACTORS FOR CHRONIC DISEASES AND THE DEVELOPMENT OF INTERVENTIONS FOR DISEASES LATER IN LIFE.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
3 3166  38 GROCERY DELIVERY TO SUPPORT HEALTHY WEIGHT GAIN AMONG PREGNANT YOUNG WOMEN WITH LOW INCOME: PROTOCOL FOR A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: EXCESSIVE WEIGHT GAIN DURING PREGNANCY IS ASSOCIATED WITH COMPLICATIONS FOR BOTH THE MOTHER AND HER INFANT INCLUDING GESTATIONAL DIABETES, HYPERTENSIVE DISORDERS, OPERATIVE DELIVERY, AND LONG-TERM OBESITY. A HEALTHY DIET DURING PREGNANCY PROMOTES HEALTHY GESTATIONAL WEIGHT GAIN AND DETERMINES FETAL EPIGENETIC PROGRAMMING IN INFANTS THAT IMPACTS RISK FOR FUTURE CHRONIC DISEASE. OBJECTIVE: THIS PROJECT WILL EXAMINE THE IMPACT OF GROCERY DELIVERY DURING PREGNANCY ON THE WEIGHT, DIET, AND HEALTH OUTCOMES OF YOUNG PREGNANT WOMEN AND THEIR INFANTS. METHODS: A THREE-ARM RANDOMIZED CONTROLLED TRIAL DESIGN WILL BE PERFORMED. A TOTAL OF 855 YOUNG PREGNANT WOMEN, AGED 14-24 YEARS, FROM ACROSS THE STATE OF MICHIGAN WILL BE ENROLLED AND RANDOMIZED EQUALLY INTO THE THREE STUDY ARMS. PARTICIPANTS IN ARM ONE (CONTROL) WILL RECEIVE USUAL CARE FROM THE SPECIAL SUPPLEMENTAL NUTRITION PROGRAM FOR WOMEN, INFANTS, AND CHILDREN (WIC); ARM TWO WILL RECEIVE WIC PLUS BIWEEKLY GROCERY DELIVERY; AND ARM THREE WILL RECEIVE WIC PLUS BIWEEKLY GROCERY AND UNSWEETENED BEVERAGE DELIVERY. WEIGHT WILL BE ASSESSED WEEKLY DURING PREGNANCY, AND TOTAL PREGNANCY WEIGHT GAIN WILL BE CATEGORIZED AS ABOVE, BELOW, OR WITHIN GUIDELINES. ADDITIONALLY, DIETARY INTAKE WILL BE ASSESSED AT THREE TIME POINTS (BASELINE, SECOND TRIMESTER, AND THIRD TRIMESTER), AND PREGNANCY OUTCOMES WILL BE EXTRACTED FROM MEDICAL RECORDS. THE APPROPRIATENESS OF PREGNANCY WEIGHT GAIN, DIET QUALITY, AND OCCURRENCE OF POOR OUTCOMES WILL BE COMPARED BETWEEN GROUPS USING STANDARD PRACTICES FOR MULTINOMIAL REGRESSION AND CONFOUNDER ADJUSTMENT. RESULTS: THIS STUDY WAS FUNDED IN APRIL 2021, DATA COLLECTION STARTED IN DECEMBER 2021, AND DATA COLLECTION IS EXPECTED TO BE CONCLUDED IN 2026. CONCLUSIONS: THIS STUDY WILL TEST WHETHER GROCERY DELIVERY OF HEALTHY FOODS IMPROVES WEIGHT, DIET, AND PREGNANCY OUTCOMES OF YOUNG MOMS WITH LOW INCOME. THE FINDINGS WILL INFORM POLICIES AND PRACTICES THAT PROMOTE A HEALTHY DIET DURING PREGNANCY, WHICH HAS MULTIGENERATIONAL IMPACTS ON HEALTH.

4 3208  34 HEAD CIRCUMFERENCE AS AN EPIGENETIC RISK FACTOR FOR MATERNAL NUTRITION. NUTRITION INDICATORS FOR MALNUTRITION CAN BE SCREENED BY MANY SIGNS SUCH AS STUNTING, UNDERWEIGHT OR OBESITY, MUSCLE WASTING, AND LOW CALORIC AND NUTRIENTS INTAKE. THOSE DEFICIENCIES ARE ALSO ASSOCIATED WITH LOW SOCIOECONOMIC STATUS. ANTHROPOMETRY CAN ASSESS NUTRITIONAL STATUS BY MATERNAL WEIGHT MEASUREMENTS DURING PREGNANCY. HOWEVER, MOST STUDIES HAVE FOCUSED PRIMARILY ON IDENTIFYING CHANGES IN WEIGHT OR BODY MASS INDEX (BMI), AND THEIR EFFECTS ON NEONATAL MEASURES AT PRESENT TIME. WHEREAS HEAD CIRCUMFERENCE (HC) HAS BEEN ASSOCIATED WITH NUTRITION IN THE PAST. WHEN THE MOTHER WAS EXPOSED TO POOR NUTRITION AND UNFAVORABLE SOCIAL CONDITIONS DURING FETAL LIFE, IT WAS HYPOTHESIZED THAT THE INTERGENERATIONAL CYCLE WAS POTENTIALLY MEDIATED BY EPIGENETIC MECHANISMS. TO INVESTIGATE THIS THEORY, MATERNAL HEAD CIRCUMFERENCE (MHC) WAS ASSOCIATED WITH NEONATAL HEAD CIRCUMFERENCE (NHC) IN PREGNANT WOMEN WITHOUT PREEXISTING CHRONIC CONDITIONS, DIFFERENTIATED BY SOCIODEMOGRAPHIC CHARACTERISTICS. A MULTIPLE LINEAR REGRESSION MODEL SHOWED THAT EACH 1 CM-INCREASE IN MHC CORRELATED WITH A 0.11 CM INCREASE IN NHC (BETA95% CI 0.07 TO 0.15). NOTWITHSTANDING, ASSOCIATIONS BETWEEN MATERNAL AND NEONATAL ANTHROPOMETRICS ACCORDING TO GESTATIONAL AGE AT BIRTH HAVE BEEN EXTENSIVELY EXPLAINED. PATH ANALYSIS SHOWED THE INFLUENCE OF SOCIAL STATUS AND THE LATENT VARIABLE WAS SOCIOECONOMIC STATUS. A MODEL OF MATERNAL HEIGHT AND HEAD CIRCUMFERENCE WAS TESTED WITH EFFECTS ON NEONATAL HC. THE SOCIAL VARIABLE LACKED SIGNIFICANCE TO PREDICT NEONATAL HC IN THE TOTAL SAMPLE (P = 0.212) AND IN THE SOUTH/SOUTHEAST (P = 0.095), IN CONTRAST TO THE NORTHEAST (P = 0.047). THIS STUDY HIGHLIGHTS THE POTENTIAL INTERGENERATIONAL INFLUENCE OF MATERNAL NUTRITION ON HC, SUGGESTING THAT MATERNAL NUTRITION MAY BE MORE RELEVANT IN FAMILIES WITH MAJOR SOCIAL VULNERABILITY.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
5 2419  27 EPIGENETIC SIGNATURE OF CHRONIC MATERNAL STRESS LOAD DURING PREGNANCY MIGHT BE A POTENTIAL BIOMARKER FOR SPONTANEOUS PRETERM BIRTH. PRETERM BIRTH IS THE LEADING CAUSE OF MORTALITY IN NEWBORN INFANTS AND CAN LEAD TO SIGNIFICANT NEONATAL MORBIDITIES. SPONTANEOUS PRETERM BIRTH ACCOUNTS FOR AT LEAST 50.0% OF ALL PRETERM BIRTHS. WE ARGUE THAT CHRONIC MATERNAL STRESS LOAD, WHICH IS AN IMPORTANT RISK FACTOR FOR SPONTANEOUS PRETERM BIRTH, COULD BE REPRESENTED BY EPIGENETIC SIGNATURE OF SEVERAL SPECIFIC GENETIC LOCI IN THE MOTHER'S BLOOD. A LITERATURE SEARCH WAS DONE IN PUBMED WITH THE FOLLOWING KEYWORDS: "DNA METHYLATION," "EPIGENETICS," "MATERNAL STRESS" AND "PRETERM BIRTH" FROM YEAR 2000 TO 2017. WE SUGGEST THAT THESE GENETIC LOCI MIGHT BE RELATED TO VULNERABILITY AND HYPERSENSIBILITY OF STRESS RESPONSE DURING PREGNANCY IN WOMEN WITH PRETERM BIRTHS. THE MOTHER'S EPI-GENETIC STRESS BIOPROFILE WAS SUPPOSED TO BE A RESULT OF CHRONIC MATERNAL STRESS LOAD SINCE HER BIRTH. THIS EPIGENETIC BIOPROFILE MIGHT ALSO BE A POTENTIAL BIOMARKER FOR SPONTANEOUS PRETERM BIRTH. DNA METHYLATION CHANGES ARE TISSUE-SPECIFIC AND HUMAN STRESS RESPONSE MANIFESTS MOSTLY THROUGH THE CENTRAL NERVOUS SYSTEM (CNS). NEVERTHELESS, WE FOUND EVIDENCE THAT METHYLATION CHANGES OF DNA ISOLATED FROM BLOOD LEUCOCYTES MIGHT BE A RELIABLE MEASURE OF STRESS-RELATED EPIGENETIC CHANGES THAT OCCUR IN THE CNS. EVALUATING BIOLOGICAL MECHANISMS THROUGH THE DEVELOPMENT OF SIMPLE ASSAYS BASED ON EPIGENETIC CHANGES TO MEASURE CHRONIC STRESS LOADS IN EXPECTANT MOTHERS CAN LEAD TO OUR ABILITY TO PREPARE MORE EFFECTIVE MEASURES FOR THE PREVENTION OF PRETERM BIRTHS, AS WELL AS LEADING TO MORE EFFECTIVE TREATMENT STRATEGIES FOR BOTH EXPECTANT MOTHERS AND THEIR NEWBORNS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
6 4072  34 MATERNAL DNA METHYLATION SIGNATURES OF ARSENIC EXPOSURE IS ASSOCIATED WITH ADULT OFFSPRING INSULIN RESISTANCE IN THE STRONG HEART STUDY. EXPOSURE TO LOW TO MODERATE ARSENIC (AS) LEVELS HAS BEEN ASSOCIATED WITH TYPE 2 DIABETES (T2D) AND OTHER CHRONIC DISEASES IN AMERICAN INDIAN COMMUNITIES. PRENATAL EXPOSURE TO AS MAY ALSO INCREASE THE RISK FOR T2D IN ADULTHOOD, AND MATERNAL AS HAS BEEN ASSOCIATED WITH ADULT OFFSPRING METABOLIC HEALTH MEASUREMENTS. WE HYPOTHESIZED THAT T2D-RELATED OUTCOMES IN ADULT OFFSPRING BORN TO WOMEN EXPOSED TO LOW TO MODERATE AS CAN BE EVALUATED UTILIZING A MATERNALLY-DERIVED MOLECULAR BIOSIGNATURE OF AS EXPOSURE. HEREIN, WE EVALUATED THE ASSOCIATION OF MATERNAL DNA METHYLATION WITH INCIDENT T2D AND INSULIN RESISTANCE (HOMEOSTATIC MODEL ASSESSMENT OF INSULIN RESISTANCE [HOMA2-IR]) IN ADULT OFFSPRING. FOR DNA METHYLATION, WE USED 20 DIFFERENTIALLY METHYLATED CYTOSINE-GUANINE DINUCLEOTIDES (CPG) PREVIOUSLY ASSOCIATED WITH THE SUM OF INORGANIC AND METHYLATED AS SPECIES (SIGMAAS) IN URINE IN THE STRONG HEART STUDY (SHS). OF THESE 20 CPGS, WE FOUND SIX CPGS NOMINALLY ASSOCIATED (P < 0.05) WITH HOMA2-IR IN A FULLY ADJUSTED MODEL THAT INCLUDED CLINICALLY RELEVANT COVARIATES AND OFFSPRING ADIPOSITY MEASUREMENTS; A SIMILAR MODEL THAT ADJUSTED INSTEAD FOR MATERNAL ADIPOSITY MEASUREMENTS FOUND THREE CPGS NOMINALLY ASSOCIATED WITH HOMA2-IR, TWO OF WHICH OVERLAPPED THE OFFSPRING ADIPOSITY MODEL. AFTER ADJUSTING FOR MULTIPLE COMPARISONS, CG03036214 REMAINED ASSOCIATED WITH HOMA2-IR (Q < 0.10) IN THE OFFSPRING ADIPOSITY MODEL. THE ODDS RATIO OF INCIDENT T2D INCREASED WITH AN INCREASE IN MATERNAL DNA METHYLATION AT ONE HOMA2-IR ASSOCIATED CPG IN THE MODEL ADJUSTING FOR OFFSPRING ADIPOSITY, CG12116137, WHEREAS ADJUSTING FOR MATERNAL ADIPOSITY HAD A MINIMAL EFFECT ON THE ASSOCIATION. OUR DATA SUGGESTS OFFSPRING ADIPOSITY, RATHER THAN MATERNAL ADIPOSITY, POTENTIALLY INFLUENCES THE EFFECTS OF MATERNAL DNAM SIGNATURES ON OFFSPRING METABOLIC HEALTH PARAMETERS. HERE, WE HAVE PRESENTED EVIDENCE SUPPORTING A ROLE FOR EPIGENETIC BIOSIGNATURES OF MATERNAL AS EXPOSURE AS A POTENTIAL BIOMARKER FOR EVALUATING RISK OF T2D-RELATED OUTCOMES IN OFFSPRING LATER IN LIFE.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                           
7 1094  34 COHORT PROFILE: THE DUTCH FAMINE BIRTH COHORT (DFBC)- A PROSPECTIVE BIRTH COHORT STUDY IN THE NETHERLANDS. PURPOSE: THE DUTCH FAMINE BIRTH COHORT STUDY WAS SET UP TO INVESTIGATE THE EFFECTS OF ACUTE MATERNAL UNDERNUTRITION OF THE 1944-1945 DUTCH FAMINE DURING THE SPECIFIC STAGES OF GESTATION ON LATER HEALTH, WITH A PARTICULAR FOCUS ON CHRONIC CARDIOVASCULAR AND METABOLIC DISEASES, AGEING AND MENTAL HEALTH. PARTICIPANTS: THE DUTCH FAMINE BIRTH COHORT CONSISTS OF 2414 SINGLETONS BORN ALIVE AND AT TERM IN THE WILHELMINA GASTHUIS IN AMSTERDAM AROUND THE TIME OF THE DUTCH FAMINE (1943-1947) WHOSE BIRTH RECORDS HAVE BEEN KEPT. THE COHORT HAS BEEN TRACED AND STUDIED SINCE 1994, WHEN THE FIRST DATA COLLECTION STARTED. THE COHORT HAS BEEN INTERVIEWED AND PHYSICALLY EXAMINED IN SEVERAL WAVES OF DATA COLLECTION SINCE THAT TIME, ALLOWING REPEATED MEASURES OF A WIDE RANGE OF PHENOTYPIC INFORMATION AS WELL AS THE COLLECTION OF BIOLOGICAL SAMPLES (BLOOD, URINE, BUCCAL SWABS), FUNCTIONAL TESTING (OF HEART, LUNGS, KIDNEY, HPA AXIS) AND IMAGING OF THE BRAIN (MRI) AND VASCULATURE (ULTRASOUND). ADDITIONALLY, GENETIC AND EPIGENETIC INFORMATION WAS COLLECTED. THROUGH LINKAGE WITH REGISTRIES, MORTALITY AND MORBIDITY INFORMATION OF THE ENTIRE COHORT HAS BEEN OBTAINED. FINDINGS TO DATE: PRENATAL FAMINE EXPOSURE HAD LASTING CONSEQUENCES FOR HEALTH IN LATER LIFE. THE EFFECTS OF FAMINE DEPENDED ON ITS TIMING DURING THE GESTATION AND THE ORGANS AND TISSUES DEVELOPING AT THAT TIME, WITH MOST EFFECTS AFTER EXPOSURE TO FAMINE IN EARLY GESTATION. THE EFFECTS OF FAMINE WERE WIDESPREAD AND AFFECTED THE STRUCTURE AND FUNCTION OF MANY ORGANS AND TISSUES, RESULTED IN ALTERED BEHAVIOUR AND INCREASED RISKS OF CHRONIC DEGENERATIVE DISEASES AND INCREASED MORTALITY. THE EFFECTS OF FAMINE WERE INDEPENDENT OF SIZE AT BIRTH, WHICH SUGGESTS THAT PROGRAMMING MAY OCCUR WITHOUT ALTERING SIZE AT BIRTH. FUTURE PLANS: AS THE COHORT AGES, WE WILL BE ASSESSING THE EFFECTS OF PRENATAL UNDERNUTRITION ON (BRAIN) AGEING, COGNITIVE DECLINE AND DEMENTIA, AS WELL AS OVERALL MORBIDITY AND MORTALITY. REGISTRATION: THE DUTCH FAMINE BIRTH COHORT IS NOT LINKED TO A CLINICAL TRIAL.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
8  496  37 ASSESSMENT OF THE IMPACT OF HIV INFECTION AND ANTI-RETROVIRAL TREATMENT ON THE CARDIOMETABOLIC HEALTH OF PREGNANT MOTHERS AND THEIR OFFSPRING (ARTMOMSBABES). BACKGROUND: THE RISK OF CARDIOVASCULAR DISEASES (CVDS) IS BECOMING MORE PREVALENT IN PREGNANT WOMEN THOUGH NOT MUCH DATA IS AVAILABLE FOR PREGNANT WOMEN WITH HUMAN IMMUNODEFICIENCY VIRUS (HIV). FOETOPLACENTAL VASCULAR ENDOTHELIAL DYSFUNCTION IS THOUGHT TO BE AT THE ORIGIN OF CHRONIC DISEASES SUCH AS DIABETES AND OBESITY LATER ON IN LIFE. BECAUSE HIV AND ANTI-RETROVIRAL TREATMENT (ARTS) ARE ASSOCIATED WITH ENDOTHELIAL DYSFUNCTION, CHILDREN EXPOSED IN UTERO TO THESE CONDITIONS MAY BE AT GREATER RISK OF DEVELOPING CVDS. DESPITE THE HIGH PREVALENCE OF HIV IN PREGNANT SOUTH AFRICAN WOMEN, LITTLE IS KNOWN ABOUT THE EFFECTS OF ART ON THE CARDIOVASCULAR HEALTH OF THE MOTHER AND OFFSPRING. HENCE, THE PROPOSED STUDY INTENDS TO INVESTIGATE HOW HIV/ARTS MAY AFFECT THE CARDIOVASCULAR HEALTH OF THE MOTHER AND OFFSPRING AT DIFFERENT TIME POINTS DURING THE PREGNANCY AND UP TO 2 YEARS AFTER BIRTH. METHODS: A LONGITUDINAL CASE-CONTROL STUDY IN HIV POSITIVE PREGNANT WOMEN ON ART AND HIV NEGATIVE PREGNANT WOMEN WILL BE CONDUCTED. ALL PREGNANT WOMEN WILL BE ASSESSED FOR CARDIO-METABOLIC RISK FACTORS AND MARKERS (LIPIDS, ANTHROPOMETRIC AND GLYCAEMIC INDIES, OXIDATIVE STRESS), HEMODYNAMIC STATUS (BLOOD PRESSURE PARAMETERS) AND VASCULAR FUNCTION (ARTERIAL COMPLIANCE, RETINAL MICROVASCULATURE, UTERINE ARTERY MEAN PULSATILITY INDEX). CHILD HEALTH WILL BE MONITORED IN UTERO AND POSTNATALLY VIA ROUTINE FOETAL HEALTH SCREENING, PLACENTAL INTEGRITY, ANTHROPOMETRY, BLOOD PRESSURE PARAMETERS, MARKERS OF OXIDATIVE STRESS AND ENDOTHELIAL FUNCTION IN CORD BLOOD AND CARDIOVASCULAR EPIGENETIC MARKERS IN URINE. DISCUSSION: THERE IS A PAUCITY OF STUDIES IN SOUTH AFRICA AND SUB-SAHARA AFRICA AS A WHOLE THAT UTILISED A LONGITUDINAL STUDY MODEL TO ASSESS THE EFFECTS OF ARTS ON VASCULAR ENDOTHELIAL CHANGES IN PREGNANT WOMEN LIVING WITH HIV AND THE CARDIOMETABOLIC HEALTH OF THEIR OFFSPRING. THIS STUDY WILL THEREFORE HELP TO MONITOR CHANGES IN CARDIOMETABOLIC RISK DURING PREGNANCY AND IN CHILDREN EXPOSED IN UTERO TO HIV-INFECTION AND ART USE. FINDINGS FROM THIS STUDY WILL PROVIDE USEFUL INFORMATION FOR DEVELOPING GUIDELINES ON THE USE OF ARTS IN PREGNANCY AND MANAGEMENT OF CARDIOMETABOLIC HEALTH OF THE OFFSPRING OF HIV POSITIVE MOTHERS.	2021	
                                                                                                                                                                                                                         
9 6084  28 THE EFFECT OF TRAINING ABOUT ENVIRONMENTAL TOXICANT BISPHENOL-A EXPOSURE IN PREGNANCY ON MATERNAL URINE BISPHENOL-A LEVEL. PURPOSE: BISPHENOL A (BPA) IS AN ENVIRONMENTAL TOXIN, CLEARLY CAPABLE OF INITIATING EPIGENETIC MODIFICATIONS, LEADING TO THE DEVELOPMENT OF NUMEROUS HUMAN ILLNESSES SUCH AS METABOLIC, REPRODUCTIVE, AND BEHAVIOURAL ABNORMALITIES. IT ALSO CAUSES OXIDATIVE STRESS, WHICH HAS BEEN SHOWN TO BE ALLEVIATED BY SELENIUM SUPPLEMENTATION. THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE EFFECT OF TRAINING OF BPA EXPOSURE DURING PREGNANCY ON URINE BPA LEVELS. METHODS: THIS RESEARCH ENROLLED 30 PREGNANT WOMEN WHO WERE IN THEIR FIRST TRIMESTER AND WERE FREE OF CHRONIC ILLNESS. WOMEN WERE ASKED QUESTIONS ON THEIR SOCIODEMOGRAPHIC FEATURES, ANTHROPOMETRIC MEASURES, OBSTETRIC CHARACTERISTICS, BPA AWARENESS LEVEL, BPA EXPOSURE AND THE HEALTH PRACTICES IN PREGNANCY SCALE AS A PRE-TEST AND POST-TEST. THE INITIAL URINE SAMPLES WERE TAKEN FROM WOMEN IN THEIR FIRST TRIMESTER AND STORED IN BPA-FREE BAGS. THEN, TRAINING WAS DELIVERED TO ENCOURAGE BPA EXPOSURE REDUCTION AND MATERNAL HEALTH AWARENESS. FIRST-TRIMESTER FACE-TO-FACE INSTRUCTION AND BROCHURE DISTRIBUTION WERE FOLLOWED BY REFRESHER, REMINDER, AND FOLLOW-UP TRAININGS DURING THE SECOND AND THIRD TRIMESTERS. URINE SAMPLES FROM WOMEN IN THEIR SECOND AND THIRD TRIMESTERS WERE OBTAINED AGAIN. THE LEVELS OF BPA IN URINE WERE MEASURED USING THE LIQUID CHROMATOGRAPHY-MASS SPECTROMETRY ON 90 SAMPLES. EACH PERSON'S URINE CONCENTRATION DIFFERS, THUS THE CREATININE LEVEL IN ALL SAMPLES WAS ALSO CALCULATED AND COMPARED TO THE BPA CONTENT, AND THE RESULTS WERE EVALUATED. RESULTS: OUR STUDY SHOWN THAT BPA EXPOSURE MAY BE LOWERED BY TRAINING. IT HAS BEEN DEMONSTRATED THAT REDUCING BPA EXPOSURE AND INCREASING KNOWLEDGE CAN RESULT IN AN IMPROVEMENT IN HEALTH STATUS. ADDITIONALLY, IT HAS BEEN DEMONSTRATED THAT TRAININGS GREATLY MINIMIZE EXPOSURE-CAUSING BEHAVIOURS. CONCLUSION: IT WAS DISCOVERED THAT WHILE THE DURATION OF A SINGLE TRAINING DOES NOT MAKE A MEANINGFUL EFFECT, THE CONTINUING OF REMINDER TRAININGS DID MAKE A SUBSTANTIAL DIFFERENCE IN THE URINE BPA LEVEL.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
10 4085  38 MATERNAL OBESITY AND GESTATIONAL DIABETES REPROGRAM THE METHYLOME OF OFFSPRING BEYOND BIRTH BY INDUCING EPIGENETIC SIGNATURES IN METABOLIC AND DEVELOPMENTAL PATHWAYS. BACKGROUND: OBESITY IS A NEGATIVE CHRONIC METABOLIC HEALTH CONDITION THAT REPRESENTS AN ADDITIONAL RISK FOR THE DEVELOPMENT OF MULTIPLE PATHOLOGIES. EPIDEMIOLOGICAL STUDIES HAVE SHOWN HOW MATERNAL OBESITY OR GESTATIONAL DIABETES MELLITUS DURING PREGNANCY CONSTITUTE SERIOUS RISK FACTORS IN RELATION TO THE APPEARANCE OF CARDIOMETABOLIC DISEASES IN THE OFFSPRING. FURTHERMORE, EPIGENETIC REMODELLING MAY HELP EXPLAIN THE MOLECULAR MECHANISMS THAT UNDERLIE THESE EPIDEMIOLOGICAL FINDINGS. THUS, IN THIS STUDY WE EXPLORED THE DNA METHYLATION LANDSCAPE OF CHILDREN BORN TO MOTHERS WITH OBESITY AND GESTATIONAL DIABETES DURING THEIR FIRST YEAR OF LIFE. METHODS: WE USED ILLUMINA INFINIUM METHYLATIONEPIC BEADCHIP ARRAYS TO PROFILE MORE THAN 770,000 GENOME-WIDE CPG SITES IN BLOOD SAMPLES FROM A PAEDIATRIC LONGITUDINAL COHORT CONSISTING OF 26 CHILDREN BORN TO MOTHERS WHO SUFFERED FROM OBESITY OR OBESITY WITH GESTATIONAL DIABETES MELLITUS DURING PREGNANCY AND 13 HEALTHY CONTROLS (MEASUREMENTS TAKEN AT 0, 6 AND 12 MONTH; TOTAL N = 90). WE CARRIED OUT CROSS-SECTIONAL AND LONGITUDINAL ANALYSES TO DERIVE DNA METHYLATION ALTERATIONS ASSOCIATED WITH DEVELOPMENTAL AND PATHOLOGY-RELATED EPIGENOMICS. RESULTS: WE IDENTIFIED ABUNDANT DNA METHYLATION CHANGES DURING CHILD DEVELOPMENT FROM BIRTH TO 6 MONTHS AND, TO A LESSER EXTENT, UP TO 12 MONTHS OF AGE. USING CROSS-SECTIONAL ANALYSES, WE DISCOVERED DNA METHYLATION BIOMARKERS MAINTAINED ACROSS THE FIRST YEAR OF LIFE THAT COULD DISCRIMINATE CHILDREN BORN TO MOTHERS WHO SUFFERED FROM OBESITY OR OBESITY WITH GESTATIONAL DIABETES. IMPORTANTLY, ENRICHMENT ANALYSES SUGGESTED THAT THESE ALTERATIONS CONSTITUTE EPIGENETIC SIGNATURES THAT AFFECT GENES AND PATHWAYS INVOLVED IN THE METABOLISM OF FATTY ACIDS, POSTNATAL DEVELOPMENTAL PROCESSES AND MITOCHONDRIAL BIOENERGETICS, SUCH AS CPT1B, SLC38A4, SLC35F3 AND FN3K. FINALLY, WE OBSERVED EVIDENCE OF AN INTERACTION BETWEEN DEVELOPMENTAL DNA METHYLATION CHANGES AND MATERNAL METABOLIC CONDITION ALTERATIONS. CONCLUSIONS: OUR OBSERVATIONS HIGHLIGHT THE FIRST SIX MONTHS OF DEVELOPMENT AS BEING THE MOST CRUCIAL FOR EPIGENETIC REMODELLING. FURTHERMORE, OUR RESULTS SUPPORT THE EXISTENCE OF SYSTEMIC INTRAUTERINE FOETAL PROGRAMMING LINKED TO OBESITY AND GESTATIONAL DIABETES THAT AFFECTS THE CHILDHOOD METHYLOME BEYOND BIRTH, WHICH INVOLVES ALTERATIONS RELATED TO METABOLIC PATHWAYS, AND WHICH MAY INTERACT WITH ORDINARY POSTNATAL DEVELOPMENT PROGRAMMES.	2023	

11 1845  33 EFFECTS OF THE MEDITERRANEAN DIET DURING PREGNANCY ON THE ONSET OF ALLERGY IN AT RISK CHILDREN: A STUDY PROTOCOL OF A MULTI-CENTER, RANDOMIZED- CONTROLLED, PARALLEL GROUPS, PROSPECTIVE TRIAL (THE PREMEDI STUDY). INTRODUCTION: MATERNAL DIET DURING PREGNANCY HAS BEEN LINKED TO OFFSPRING ALLERGY RISK AND IT COULD REPRESENT A POTENTIAL TARGET FOR ALLERGY PREVENTION. THE MEDITERRANEAN DIET (MD) IS CONSIDERED ONE OF THE HEALTHIEST DIETARY MODELS. RANDOMIZED-CONTROLLED TRIALS ON THE EFFECT OF MD IN PREVENTING PEDIATRIC ALLERGIC DISEASES ARE STILL NEEDED. METHODS AND ANALYSIS: THE MEDITERRANEAN DIET DURING PREGNANCY STUDY (PREMEDI) WILL BE A 9-MONTH MULTI-CENTER, RANDOMIZED-CONTROLLED, PARALLEL GROUPS, PROSPECTIVE TRIAL. HEALTHY WOMEN (20-35 YEARS) AT THEIR FIRST TRIMESTER OF PREGNANCY AT RISK FOR ATOPY BABY, WILL BE RANDOMLY ALLOCATED TO GROUP 1 (STANDARD OBSTETRICAL AND GYNECOLOGICAL FOLLOW-UP AND NUTRITIONAL COUNSELING TO PROMOTE MD) OR GROUP 2 (STANDARD OBSTETRICAL AND GYNECOLOGICAL FOLLOW-UP ALONE). 138 MOTHER-CHILD PAIR PER GROUP WILL BE NEEDED TO DETECT A REDUCTION IN CUMULATIVE INCIDENCE OF >/=1 ALLERGIC DISEASE AT 24 MONTHS OF AGE. THE PRIMARY STUDY AIM WILL BE THE EVALUATION OF THE OCCURRENCE OF ALLERGIC DISORDERS IN THE FIRST 24 MONTHS OF LIFE. THE SECONDARY AIMS WILL BE THE EVALUATION OF MATERNAL WEIGHT GAIN, PREGNANCY/PERINATAL COMPLICATIONS, GROWTH INDICES AND OCCURRENCE OF OTHER CHRONIC DISORDERS, MOTHER-CHILD PAIR ADHERENCE TO MD AND GUT MICROBIOME FEATURES, BREASTFEEDING DURATION AND BREAST MILK COMPOSITION, EPIGENETIC MODULATION OF GENES INVOLVED IN IMMUNE SYSTEM, AND METABOLIC PATHWAYS IN THE OFFSPRING. ETHICS AND DISSEMINATION: THE STUDY PROTOCOL HAS BEEN APPROVED BY THE ETHICS COMMITTEE OF THE UNIVERSITY OF NAPLES FEDERICO II (NUMBER 283/21) AND IT WILL BE CONDUCTED IN ACCORDANCE WITH THE HELSINKI DECLARATION (FORTALEZA REVISION, 2013), THE GOOD CLINICAL PRACTICE STANDARDS (CPMP/ICH/135/95), THE ITALIAN DECREE-LAW 196/2003 REGARDING PERSONAL DATA AND THE EUROPEAN REGULATIONS ON THIS SUBJECT. THE STUDY HAS BEEN REGISTERED IN THE CLINICAL TRIALS PROTOCOL REGISTRATION SYSTEM.

12  649  35 BIRTHWEIGHT, MATERNAL WEIGHT TRAJECTORIES AND GLOBAL DNA METHYLATION OF LINE-1 REPETITIVE ELEMENTS. LOW BIRTHWEIGHT, PREMATURE BIRTH, INTRAUTERINE GROWTH RETARDATION, AND MATERNAL MALNUTRITION HAVE BEEN RELATED TO AN INCREASED RISK OF CARDIOVASCULAR DISEASE, TYPE 2 DIABETES MELLITUS, OBESITY, AND NEUROPSYCHIATRIC DISORDERS LATER IN LIFE. CONVERSELY, HIGH BIRTHWEIGHT HAS BEEN LINKED TO FUTURE RISK OF CANCER. GLOBAL DNA METHYLATION ESTIMATED BY THE METHYLATION OF REPETITIVE SEQUENCES IN THE GENOME IS AN INDICATOR OF SUSCEPTIBILITY TO CHRONIC DISEASES. WE USED DATA AND BIOSPECIMENS FROM AN EPIGENETIC BIRTH COHORT TO EXPLORE THE ASSOCIATION BETWEEN TRAJECTORIES OF FETAL AND MATERNAL WEIGHT AND LINE-1 METHYLATION IN 319 MOTHER-CHILD DYADS. NEWBORNS WITH LOW OR HIGH BIRTHWEIGHT HAD SIGNIFICANTLY LOWER LINE-1 METHYLATION LEVELS IN THEIR CORD BLOOD COMPARED TO NORMAL WEIGHT INFANTS AFTER ADJUSTING FOR GESTATIONAL AGE, SEX OF THE CHILD, MATERNAL AGE AT DELIVERY, AND MATERNAL SMOKING DURING PREGNANCY (P = 0.007 AND P = 0.036, RESPECTIVELY), BUT THE MAGNITUDE OF THE DIFFERENCE WAS SMALL. INFANTS BORN PREMATURELY ALSO HAD LOWER LINE-1 METHYLATION LEVELS IN CORD BLOOD COMPARED TO TERM INFANTS, AND THIS DIFFERENCE, THOUGH SMALL, WAS STATISTICALLY SIGNIFICANT (P = 0.004). WE DID NOT FIND IMPORTANT ASSOCIATIONS BETWEEN MATERNAL PREPREGNANCY BMI OR GESTATIONAL WEIGHT GAIN AND GLOBAL METHYLATION OF THE CORD BLOOD OR FETAL PLACENTAL TISSUE. IN CONCLUSION, WE FOUND SIGNIFICANT DIFFERENCES IN CORD BLOOD LINE-1 METHYLATION AMONG NEWBORNS WITH LOW AND HIGH BIRTHWEIGHT AS WELL AS AMONG PREMATURELY BORN INFANTS. FUTURE STUDIES MAY ELUCIDATE WHETHER CHROMOSOMAL INSTABILITIES OR OTHER FUNCTIONAL CONSEQUENCES OF THESE CHANGES CONTRIBUTE TO THE INCREASED RISK OF CHRONIC DISEASES AMONG INDIVIDUALS WITH THESE CHARACTERISTICS.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
13 5619  38 SCALING UP PRENATAL NUTRITION COULD REDUCE THE GLOBAL BURDEN OF NONCOMMUNICABLE DISEASES IN THE NEXT GENERATION: A MODELING ANALYSIS. BACKGROUND: NUTRITIONAL CONDITIONS DURING PREGNANCY MAY INFLUENCE THE EPIGENETIC DEVELOPMENT OF AN INDIVIDUAL AND CONSEQUENTLY THEIR LATER-LIFE RISK OF NONCOMMUNICABLE DISEASE (NCD). IMPROVING NUTRITION FOR PREGNANT FEMALES MAY THEREFORE SERVE THE DUAL PURPOSE OF DIRECTLY IMPROVING PREGNANCY OUTCOMES AND PREVENTING NCDS IN THE NEXT GENERATION. OBJECTIVES: WE ESTIMATED THE IMPACT OF PRENATAL SUPPLEMENTATION WITH IRON AND FOLIC ACID (IFA), MULTIPLE MICRONUTRIENTS (MMS), OR CALCIUM AT 50%, 75%, OR 90% COVERAGE ON FUTURE NCDS BY AGE AND SEX IN 2015. METHODS: WE USED SECONDARY DATA SOURCES FROM 132 COUNTRIES TO QUANTIFY THE CASES OF DIABETES AND HYPERTENSION AND THE DEATHS FROM SELECTED NCDS THAT COULD BE AVERTED OR DELAYED BY SCALING UP PRENATAL MICRONUTRIENT SUPPLEMENTATION. RESULTS: GLOBALLY, >51,000 NCD DEATHS, 6 MILLION CASES OF HYPERTENSION, AND 3 MILLION CASES OF DIABETES COULD BE PREVENTED PER OFFSPRING BIRTH COHORT IF MOTHERS WERE PRENATALLY SUPPLEMENTED WITH MMS AT 90% COVERAGE. FOR IFA THESE NUMBERS WOULD BE ROUGHLY HALF. CALCIUM SUPPLEMENTATION AT 90% COULD DELAY 51,000 DEATHS PER BIRTH COHORT. OUR MODEL SUGGESTS THAT SUBSTANTIAL NUMBERS OF NCD DEATHS AND CASES OF HYPERTENSION AND DIABETES COULD BE PREVENTED IN FUTURE GENERATIONS BY SCALING UP MICRONUTRIENT SUPPLEMENTATION FOR MOTHERS DURING PREGNANCY. CONCLUSIONS: HIGHLIGHTING THE ADDITIONAL BENEFITS OF PROVEN NUTRITION INTERVENTIONS IS CRITICAL IN ENSURING ADEQUATE AND SUSTAINED INVESTMENTS, AND PROGRAMMATIC INTEGRATION. AS THE DOUBLE BURDEN OF DISEASE CONTINUES TO GROW, POPULATION-WIDE EFFORTS TO SCALE UP MICRONUTRIENT SUPPLEMENTATION TO PREGNANT FEMALES COULD HELP PREVENT BOTH UNDERNUTRITION AND CHRONIC DISEASE.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
14  167  23 ABNORMAL PLACENTATION ASSOCIATED WITH INFERTILITY AS A MARKER OF OVERALL HEALTH. INFERTILITY AND THE FERTILITY TREATMENTS UTILIZED ARE ASSOCIATED WITH ABNORMAL PLACENTATION LEADING TO ADVERSE PREGNANCY OUTCOMES RELATED TO PLACENTATION, INCLUDING PRETERM BIRTH, LOW BIRTH WEIGHT, PLACENTA ACCRETE AND PLACENTA PREVIA. THIS MAY BE DUE TO THE UNDERLYING GENETICS PREDISPOSING TO INFERTILITY OR THE EPIGENETIC CHANGES ASSOCIATED WITH THE FERTILITY TREATMENTS UTILIZED, AS SPECIFIC DISEASE STATES LEADING TO INFERTILITY ARE AT INCREASED RISK OF ADVERSE OUTCOMES, INCLUDING PLACENTAL ABRUPTION, FETAL LOSS, GDM, AND OUTCOMES RELATED TO PLACENTATION, AS WELL AS THE TREATMENTS UTILIZED INCLUDING IN VITRO FERTILIZATION (IVF) AND NIFT (NON-IVF FERTILITY TREATMENT). PLACENTATION DEFECTS, LEADING TO ADVERSE MATERNAL AND FETAL OUTCOMES, WHICH ARE MORE PRONOUNCED IN THE INFERTILE POPULATION, OCCUR DUE TO CHANGES IN TROPHOBLAST INVASION, VASCULAR DEFECTS, CHANGES IN THE ENVIRONMENTAL MILIEU, CHRONIC INFLAMMATION AND OXIDATIVE STRESS. THESE SIMILAR PROCESSES ARE RECOGNIZED AS MAJOR CONTRIBUTORS TO LIFELONG RISK OF CARDIOVASCULAR AND METABOLIC DISEASE FOR BOTH THE MOTHER AND HER OFFSPRING. THUS, ABNORMAL PLACENTATION, FOUND TO BE MORE PREVALENT IN THE INFERTILE POPULATION, MAY BE THE KEY TO BETTER UNDERSTAND HOW INFERTILITY AFFECTS OVERALL AND LONG TERM HEALTH.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
15   14  31 3RD COLLEGE OF PAEDIATRICS AND CHILD HEALTH LECTURE--THE PAST, THE PRESENT AND THE SHAPE OF THINGS TO COME.. THE GROWTH TRENDS OF SINGAPORE CHILDREN SPANNING 5 DECADES ARE REVIEWED, BASED ON 8 ANTHROPOMETRIC STUDIES FROM 1957 TILL 2002. THE HEIGHTS OF PRE-SCHOOL CHILDREN AND SCHOOL AGE CHILDREN APPEAR TO HAVE OPTIMISED ACCORDING TO THEIR GENETIC POTENTIAL, BUT THE WEIGHTS AND BODY MASS INDICES OF CHILDREN STILL APPEAR TO BE INCREASING FROM 6 TO 18 YEARS FOR BOTH SEXES, PROBABLY AS A CONSEQUENCE OF INCREASING AFFLUENCE. THIS TREND IS REFLECTED IN THE INCREASING OBESITY PREVALENCE IN SCHOOL CHILDREN OVER THE PAST 30 YEARS, AND THE CONCOMITANT INCREASED MORBIDITY ASSOCIATED WITH THE METABOLIC SYNDROME, NECESSITATES FURTHER RESEARCH INTO THE CAUSES OF OBESITY. BARKER'S HYPOTHESIS FIRST SUGGESTED THAT CHANGES IN THE INTRA-UTERINE ENVIRONMENT CAN CAUSE FETAL ADAPTATIONS WHICH PERSIST INTO ADULTHOOD, AND ARE RESPONSIBLE FOR MANY CHRONIC DISEASES OF ADULT LIFE. MORE RECENTLY, INTENSE RESEARCH IN THE FIELD OF EPIGENETICS SUGGESTS THAT THE ENVIRONMENT CAN ALSO INFLUENCE THE PHENOTYPE THROUGH GENE EXPRESSION, THROUGH MODIFICATION OF DNA METHYLATION AND HISTONES WHICH, IN TURN, INFLUENCES GENE EXPRESSION. THE CHALLENGE FOR THE FUTURE IS TO DETERMINE IF THERE ARE CLEAR EPIGENETIC CHANGES, WHICH ARE RESPONSIBLE FOR THE INCREASED PREVALENCE OF CHILDHOOD AND ADOLESCENT OBESITY, AND WHETHER THESE CHANGES ARE TRANSMITTED THROUGH GENERATIONS. UNRAVELLING THESE EPIGENETIC MECHANISMS MAY BE THE KEY TO THE PREVENTION OF OBESITY AND THE METABOLIC SYNDROME.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
16 4090  35 MATERNAL PRE-PREGNANCY BMI, OFFSPRING EPIGENOME-WIDE DNA METHYLATION, AND CHILDHOOD OBESITY: FINDINGS FROM THE BOSTON BIRTH COHORT. BACKGROUND: MATERNAL PRE-PREGNANCY OBESITY IS AN ESTABLISHED RISK FACTOR FOR CHILDHOOD OBESITY. INVESTIGATING EPIGENETIC ALTERATIONS INDUCED BY MATERNAL OBESITY DURING FETAL DEVELOPMENT COULD GAIN MECHANISTIC INSIGHT INTO THE DEVELOPMENTAL ORIGINS OF CHILDHOOD OBESITY. WHILE OBESITY DISPROPORTIONATELY AFFECTS UNDERREPRESENTED RACIAL AND ETHNIC MOTHERS AND CHILDREN IN THE USA, FEW STUDIES INVESTIGATED THE ROLE OF PRENATAL EPIGENETIC PROGRAMMING IN INTERGENERATIONAL OBESITY OF THESE HIGH-RISK POPULATIONS. METHODS: THIS STUDY INCLUDED 903 MOTHER-CHILD PAIRS FROM THE BOSTON BIRTH COHORT, A PREDOMINANTLY URBAN, LOW-INCOME MINORITY BIRTH COHORT. MOTHER-INFANT DYADS WERE ENROLLED AT BIRTH AND THE CHILDREN WERE FOLLOWED PROSPECTIVELY TO AGE 18 YEARS. INFINIUM METHYLATION EPIC BEADCHIP WAS USED TO MEASURE EPIGENOME-WIDE METHYLATION LEVEL OF CORD BLOOD. WE PERFORMED AN EPIGENOME-WIDE ASSOCIATION STUDY OF MATERNAL PRE-PREGNANCY BODY MASS INDEX (BMI) AND CORD BLOOD DNA METHYLATION (DNAM). TO QUANTIFY THE DEGREE TO WHICH CORD BLOOD DNAM MEDIATES THE MATERNAL BMI-CHILDHOOD OBESITY, WE FURTHER INVESTIGATED WHETHER MATERNAL BMI-ASSOCIATED DNAM SITES IMPACT BIRTHWEIGHT OR CHILDHOOD OVERWEIGHT OR OBESITY (OWO) FROM AGE 1 TO AGE 18 AND PERFORMED CORRESPONDING MEDIATION ANALYSES. RESULTS: THE STUDY SAMPLE CONTAINED 52.8% MATERNAL PRE-PREGNANCY OWO AND 63.2% OFFSPRING OWO AT AGE 1-18 YEARS. MATERNAL BMI WAS ASSOCIATED WITH CORD BLOOD DNAM AT 8 CPG SITES (GENOME-WIDE FALSE DISCOVERY RATE [FDR] < 0.05). AFTER ACCOUNTING FOR THE POSSIBLE INTERPLAY OF MATERNAL BMI AND SMOKING, 481 CPG SITES WERE DISCOVERED FOR ASSOCIATION WITH MATERNAL BMI. AMONG THEM 123 CPGS WERE ASSOCIATED WITH CHILDHOOD OWO, RANGING FROM 42% DECREASE TO 87% INCREASE IN OWO RISK FOR EACH SD INCREASE IN DNAM. A TOTAL OF 14 IDENTIFIED CPG SITES SHOWED A SIGNIFICANT MEDIATION EFFECT ON THE MATERNAL BMI-CHILD OWO ASSOCIATION (FDR < 0.05), WITH MEDIATING PROPORTION RANGING FROM 3.99% TO 25.21%. SEVERAL OF THESE 14 CPGS WERE MAPPED TO GENES IN ASSOCIATION WITH ENERGY BALANCE AND METABOLISM (AKAP7) AND ADULTHOOD METABOLIC SYNDROME (CAMK2B). CONCLUSIONS: THIS PROSPECTIVE BIRTH COHORT STUDY IN A HIGH-RISK YET UNDERSTUDIED US POPULATION FOUND THAT MATERNAL PRE-PREGNANCY OWO SIGNIFICANTLY ALTERED DNAM IN NEWBORN CORD BLOOD AND PROVIDED SUGGESTIVE EVIDENCE OF EPIGENETIC INVOLVEMENT IN THE INTERGENERATIONAL RISK OF OBESITY.	2023	
                                                                           
17 1408  40 DIETARY INTAKE IS ASSOCIATED WITH RESPIRATORY HEALTH OUTCOMES AND DNA METHYLATION IN CHILDREN WITH ASTHMA. BACKGROUND: ASTHMA IS AN INCREASINGLY COMMON CHRONIC DISEASE AMONG CHILDREN, AND DATA POINT TOWARD A COMPLEX MECHANISM INVOLVING GENETIC, ENVIRONMENTAL AND EPIGENETIC FACTORS. EPIGENETIC MODIFICATIONS SUCH AS DNA HYPO- OR HYPER-METHYLATION HAVE BEEN SHOWN TO OCCUR IN RESPONSE TO ENVIRONMENTAL EXPOSURES INCLUDING DIETARY NUTRIENTS. METHODS: WITHIN THE CONTEXT OF THE ASTHMA RANDOMIZED TRIAL OF INDOOR WOOD SMOKE (ARTIS) STUDY, WE INVESTIGATED RELATIONSHIPS BETWEEN DIET, ASTHMA HEALTH MEASURES, AND DNA METHYLATION. ASTHMA HEALTH MEASURES INCLUDED A QUALITY OF LIFE INSTRUMENT, DIURNAL PEAK FLOW VARIABILITY (DPFV) AND FORCED EXPIRATORY VOLUME IN THE FIRST SECOND (FEV(1)). DIETARY INTAKE WAS ASSESSED WITH A FOOD FREQUENCY QUESTIONNAIRE. METHYLATION LEVELS OF LINE-1 REPETITIVE ELEMENT AND TWO PROMOTER CPG SITES FOR INTERFERON GAMMA (IFNGAMMA, -186 AND -54) FROM BUCCAL CELL DNA WERE MEASURED USING PYROSEQUENCING ASSAYS. RESULTS: DATA WERE COLLECTED ON 32 CHILDREN WITH ASTHMA LIVING IN WESTERN MONTANA WHO WERE RECRUITED TO THE ARTIS STUDY. SELENIUM AND SEVERAL METHYL DONOR DIETARY NUTRIENTS WERE POSITIVELY ASSOCIATED WITH THE ASTHMA QUALITY OF LIFE MEASURE. INTAKE OF METHYL DONATING NUTRIENTS INCLUDING FOLATE WAS POSITIVELY ASSOCIATED LINE-1 METHYLATION AND NEGATIVELY ASSOCIATED WITH IFNGAMMA CPG-186. HIGHER LEVELS OF LINE-1 METHYLATION WERE ASSOCIATED WITH GREATER DPFV. CONCLUSION: WE IDENTIFIED SEVERAL NUTRIENTS THAT WERE ASSOCIATED WITH IMPROVED QUALITY OF LIFE MEASURES AMONG CHILDREN WITH ASTHMA. THE IFNGAMMA PROMOTER CPG SITE -186 BUT NOT -54 WAS ASSOCIATED WITH THE INTAKE OF SELECTED DIETARY NUTRIENTS. HOWEVER, IN THIS SMALL POPULATION OF CHILDREN WITH ASTHMA, THE IFNGAMMA PROMOTER CPG SITES WERE NOT ASSOCIATED WITH RESPIRATORY HEALTH MEASURES SO IT REMAINS UNCLEAR THROUGH WHICH EPIGENETIC MECHANISM THESE NUTRIENTS ARE IMPACTING THE QUALITY OF LIFE MEASURE. THESE FINDINGS ADD TO THE EVIDENCE THAT DIETARY NUTRIENTS, PARTICULARLY FOODS CONTAINING METHYL DONORS, MAY BE IMPORTANT FOR EPIGENETIC REGULATION AS IT PERTAINS TO THE CONTROL OF ASTHMA.

18 2999  33 GENETIC VARIATION, STRESS, AND PHYSIOLOGICAL STRESS RESPONSE IN ADULTS WITH FOOD ALLERGY OR CELIAC DISEASE. BACKGROUND: PERSISTENTLY HIGH CHRONIC STRESS CAN LEAD TO MALADAPTIVE PSYCHOLOGICAL, BEHAVIORAL, AND PHYSIOLOGICAL STRESS RESPONSES AND POOR MENTAL AND PHYSICAL HEALTH, HIGHLIGHTING THE IMPORTANCE OF IDENTIFYING INDIVIDUALS AT INCREASED RISK. CHRONIC HEALTH CONDITION DIAGNOSIS AND GENETICS ARE 2 CHARACTERISTICS THAT CAN INFLUENCE STRESS, STRESS RESPONSE, AND HEALTH OUTCOMES. PURPOSE: FOOD ALLERGY (FA) AND CELIAC DISEASE (CD) REQUIRE CONSTANT VIGILANCE IN DAILY LIFE AND CAN LEAD TO INCREASED STRESS. THE PURPOSE OF THIS EXPLORATORY ANALYSIS WAS TO EXAMINE THE ASSOCIATION OF VARIANTS IN SELECTED STRESS-RELATED GENES WITH STRESS EXPOSURES, STRESS, CLINICAL MEASURES OF PHYSIOLOGICAL STRESS RESPONSE, AND MENTAL HEALTH SYMPTOMS IN ADULTS WITH AND WITHOUT FA OR CD. METHODS: WE COMPARED STRESS EXPOSURES, SYMPTOMS OF PTSD, DEPRESSION, ANXIETY, AND STRESS, BMI, AND WAIST-HIP RATIO BETWEEN CASES AND CONTROLS. WE ANALYZED THE ASSOCIATION OF SNPS IN GENES WITH KNOWN OR HYPOTHESIZED ASSOCIATIONS WITH STRESS-RELATED MEASURES IN 124 CASES AND 124 MATCHED CONTROLS: CRHBP (RS7718461, RS10474485), CRHR1 (RS242940) AND OXTR (RS2268490). FOR THIS EXPLORATORY STUDY, P-VALUES </= 0.10 WERE CONSIDERED SUGGESTIVE. RESULTS: FOR CASES AND CONTROLS, RS7718461 WAS ASSOCIATED WITH STRESS SYMPTOMS, RS2268490 WITH SYMPTOMS OF STRESS AND PTSD, AND RS242940 WITH SYMPTOMS OF STRESS, PTSD, ANXIETY, AND DEPRESSION. FURTHER ANALYSES FOUND THAT STRESS-RELATED OUTCOMES IN INDIVIDUALS WITH FA OR CD MAY BE INFLUENCED BY SNP GENOTYPE. CONCLUSIONS: GIVEN THESE SUGGESTIVE FINDINGS, LARGER PROSPECTIVE STUDIES SHOULD EXAMINE SIMILAR RELATIONSHIPS IN INDIVIDUALS WITH OTHER CHRONIC HEALTH CONDITIONS, INCORPORATING FACTORS SUCH AS ENVIRONMENTAL EXPOSURES, INDIVIDUAL EXPERIENCES, AND EPIGENETIC MODIFICATIONS.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
19 1755  35 EARLY NUTRITION AND LATER OUTCOMES IN PRETERM INFANTS. THE DEVELOPMENTAL ORIGINS OF HEALTH AND DISEASE IS AN EMERGING AREA OF INTEREST THAT AMALGAMATES MANY AREAS OF SCIENTIFIC STUDIES AND ENCOMPASSES A WIDE RANGE OF DIVERSE DISCIPLINES FROM EPIDEMIOLOGY TO MOLECULAR BIOLOGY. EVIDENCE HAS ACCUMULATED TO SHOW THAT EARLY LIFE EXPERIENCES, BOTH IN UTERO AND IN INFANCY HAVE LONG-TERM EFFECTS ON MANY BODY SYSTEMS. THERE ARE NOW GOOD DATA TO SHOW THAT SUBOPTIMAL IN UTERO GROWTH, ESPECIALLY WHEN COMBINED WITH RAPID GROWTH ACCELERATION IN EARLY POSTNATAL LIFE MAY INCREASE THE RISK OF LATER LIFE METABOLIC DISEASE. THE MECHANISMS ARE COMPLEX BUT LIKELY TO INVOLVE EPIGENETIC MARKS SUCH AS DNA METHYLATION. PRETERM INFANTS FREQUENTLY EXPERIENCE SUBOPTIMAL NUTRIENT INTAKES IN EARLY POSTNATAL LIFE AND EXHIBIT GROWTH FAILURE WITHIN THE NICU. THEY ALSO RECEIVE PRODUCTS THAT MAY NOT PROVIDE EITHER AN OPTIMAL QUANTITY OR QUALITY OF NUTRIENTS. FOLLOW-UP STUDIES HAVE NOW SHOWN MUCH HIGHER RISKS FOR LONG-TERM CHRONIC DISEASE IN CHILDREN AND ADULTS WHO WERE BORN PRETERM. THERE ARE HIGHER LEVELS OF INSULIN RESISTANCE AND ABNORMAL PARTITIONING OF FAT DEPOSITION. THE ONSET OF PUBERTY SEEMS EARLIER, AVERAGE HEIGHT IS LESS AND BLOOD PRESSURE, MEASURES OF VASCULAR HEALTH AND LIPID PROFILES SUGGEST CARDIOVASCULAR HEALTH IS LIKELY TO DIFFER FROM HEALTHY TERM BORN CONTROLS. DESPITE THIS, THERE ARE NO DATA TO SUGGEST AN OVERALL BENEFIT OF LIMITING NUTRIENT INTAKE, OR RESTRICTING GROWTH IN PRETERM INFANTS. THERE ARE STRONG DATA TO SHOW THAT THE PRETERM BRAIN IS EXQUISITELY VULNERABLE TO UNDERNUTRITION, AND THAT SUBOPTIMAL NUTRIENT INTAKES MAY PERMANENTLY AFFECT LATER COGNITIVE ATTAINMENT. A CLINICAL FOCUS ON EARLY NUTRIENT INTAKES AND BREAST MILK PROVISION IS KEY TO OPTIMISING LONG-TERM HEALTH OUTCOMES.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
20 1578  32 DNA METHYLATION PROFILE OF A RURAL COHORT EXPOSED TO EARLY-ADVERSITY AND MALNUTRITION: AN EXPLORATORY ANALYSIS. BARKER'S HYPOTHESIS AFFIRMS THAT UNDERNOURISHMENT IN EARLY-LIFE INDUCES METABOLIC REPROGRAMMING THAT COMPROMISES ORGANISM FUNCTIONS LATER IN LIFE, LEADING TO AGE-RELATED DISEASES. WE ARE EXPOSED TO ENVIRONMENTAL AND SOCIAL CONDITIONS THAT IMPACT OUR LIFE TRAJECTORIES, LEADING TO AGEING PHENOTYPES AS WE GROW. EPIGENETIC MECHANISMS CONSTITUTE THE LINK BETWEEN BOTH EXTERNAL STIMULI AND GENETIC PROGRAMMING. STUDIES HAVE FOCUSED ON DESCRIBING THE EFFECT OF EARLY ADVERSE EVENTS SUCH AS TRAUMA, FAMINES, OR CHILDHOOD LABOR ON EPIGENETIC MARKERS IN ADULTHOOD AND THE ELDERLY. HOWEVER, WE LACK INFORMATION ON EPIGENETIC PROGRAMMING IN INDIVIDUALS BORN IN RURAL COMMUNITIES FROM UNDERDEVELOPED COUNTRIES, EXPOSED TO NEGATIVE INFLUENCES DURING FETAL AND POSTNATAL DEVELOPMENT, PARTICULARLY CHRONIC MALNUTRITION. HENCE, IN THIS EXPLORATORY ANALYSIS, WE CHARACTERIZE THE EPIGENOME OF INDIVIDUALS AND SOME PARENTS FROM TLALTIZAPAN (A RURAL COMMUNITY IN MEXICO ORIGINALLY STUDIED ALMOST 50 YEARS AGO) AND COLLECT ANTHROPOMETRIC DATA ON GROWTH AND DEVELOPMENT, AS WELL ON THE LIVING CONDITIONS OF THE FAMILIES. OUR RESULTS HELP BUILD A BIOLOGICAL HYPOTHESIS INDICATING THAT MOST OF THE EPIGENETIC AGE MEASURES OF THE SUBJECTS ARE SIGNIFICANTLY DIFFERENT AMONG THEM. INTERESTINGLY, THE MOST AFFECTED METHYLATED REGIONS CORRESPOND TO PATHWAYS INVOLVED IN NEURONAL SYSTEM DEVELOPMENT, REPRODUCTIVE BEHAVIOUR, LEARNING AND MEMORY REGULATION.	2022
