1  3786 235 INTERGENERATIONAL INFLUENCES ON CHILD GROWTH AND UNDERNUTRITION. INTERGENERATIONAL EFFECTS ON LINEAR GROWTH ARE WELL DOCUMENTED. SEVERAL GENERATIONS ARE NECESSARY IN ANIMAL MODELS TO 'WASH OUT' EFFECTS OF UNDERNUTRITION, CONSISTENT WITH THE UNFOLDING OF THE SECULAR TREND IN HEIGHT IN EUROPE AND NORTH AMERICA. BIRTHWEIGHT IS CORRELATED ACROSS GENERATIONS AND SHORT MATERNAL STATURE, WHICH REFLECTS INTRAUTERINE AND INFANT GROWTH FAILURE, IS ASSOCIATED WITH LOW BIRTHWEIGHT, CHILD STUNTING, DELIVERY COMPLICATIONS AND INCREASED CHILD MORTALITY, EVEN AFTER ADJUSTING FOR SOCIO-ECONOMIC STATUS. A NUTRITION INTERVENTION IN GUATEMALA REDUCED CHILDHOOD STUNTING; IT ALSO IMPROVED GROWTH OF THE NEXT GENERATION, BUT ONLY IN THE OFFSPRING OF GIRLS. POSSIBLE MECHANISMS EXPLAINING INTERGENERATIONAL EFFECTS ON LINEAR GROWTH ARE NOT MUTUALLY EXCLUSIVE AND INCLUDE, AMONG OTHERS, SHARED GENETIC CHARACTERISTICS, EPIGENETIC EFFECTS, PROGRAMMING OF METABOLIC CHANGES, AND THE MECHANICS OF A REDUCED SPACE FOR THE FETUS TO GROW. THERE ARE ALSO SOCIO-CULTURAL FACTORS AT PLAY THAT ARE IMPORTANT SUCH AS THE INTERGENERATIONAL TRANSMISSION OF POVERTY AND THE FEAR OF BIRTHING A LARGE BABY, WHICH LEADS TO 'EATING DOWN' DURING PREGNANCY. IT IS NOT CLEAR WHETHER THERE IS AN UPPER LIMIT FOR IMPACT ON INTRAUTERINE AND INFANT LINEAR GROWTH THAT PROGRAMMES IN DEVELOPING COUNTRIES COULD ACHIEVE THAT IS SET BY EARLY CHILDHOOD MALNUTRITION IN THE MOTHER. SUBSTANTIAL IMPROVEMENTS IN LINEAR GROWTH CAN BE ACHIEVED THROUGH ADOPTION AND MIGRATION, AND IN A FEW SELECTED COUNTRIES, FOLLOWING RAPID ECONOMIC AND SOCIAL DEVELOPMENT. IT WOULD SEEM, DESPITE CLEAR DOCUMENTATION OF INTERGENERATIONAL EFFECTS, THAT NEARLY NORMAL LENGTHS CAN BE ACHIEVED IN CHILDREN BORN TO MOTHERS WHO WERE MALNOURISHED IN CHILDHOOD WHEN PROFOUND IMPROVEMENTS IN HEALTH, NUTRITION AND THE ENVIRONMENT TAKE PLACE BEFORE CONCEPTION. TO ACHIEVE SIMILAR LEVELS OF IMPACT THROUGH PUBLIC HEALTH PROGRAMMES ALONE IN POOR COUNTRIES IS HIGHLY UNLIKELY. THE REALITY IN POOR COUNTRIES LIMITS THE SCOPE, QUALITY AND COVERAGE OF PROGRAMMES THAT CAN BE IMPLEMENTED AND MODEST IMPACT SHOULD BE EXPECTED INSTEAD. THE LANCET SERIES ON MATERNAL AND CHILD UNDERNUTRITION ESTIMATED THAT IMPLEMENTATION TO SCALE OF PROVEN INTERVENTIONS IN HIGH BURDEN COUNTRIES WOULD REDUCE STUNTING BY ONE-THIRD; THIS IS PERHAPS A REALISTIC UPPER BOUND FOR IMPACT FOR HIGH QUALITY PROGRAMMES, UNLESS ACCOMPANIED BY SWEEPING IMPROVEMENTS IN SOCIAL SERVICES AND MARKED REDUCTIONS IN POVERTY. FINALLY, BECAUSE SO MUCH CAN BE ACHIEVED IN A SINGLE GENERATION, INTERGENERATIONAL INFLUENCES ARE UNLIKELY TO BE AN IMPORTANT EXPLANATION FOR LACK OF PROGRAMME IMPACT AIMED AT THE WINDOW OF THE FIRST 1000 DAYS. FAILURE TO PREVENT LINEAR GROWTH FAILURE IN DEVELOPING COUNTRIES HAS SERIOUS CONSEQUENCES FOR SHORT- AND LONG-TERM HEALTH AS WELL AS FOR THE FORMATION OF HUMAN CAPITAL. THE NUTRITION TRANSITION HAS CREATED A DOUBLE BURDEN BY ADDING OBESITY AND RELATED CHRONIC DISEASES TO THE PUBLIC HEALTH AGENDA OF COUNTRIES STILL STRUGGLING WITH THE 'OLD' PROBLEMS OF MATERNAL AND CHILD UNDERNUTRITION. THE CHALLENGE AHEAD IS TO INCREASE EFFORTS TO PREVENT LINEAR GROWTH FAILURE WHILE KEEPING CHILD OVERWEIGHT AT BAY.	2012	

2  6714  42 VISION OF RESEARCH ON HUMAN LINEAR GROWTH. THE HUMAN BODY GROWS IN LENGTH FROM CONCEPTION TO THE MAXIMAL ADULT HEIGHT OVER TWO DECADES. THE SHORTEST MALE POPULATION AVERAGES APPROXIMATELY 150 CM AND THE TALLEST APPROXIMATELY 183 CM. NONETHELESS THE DIMENSIONS OF HEAD AND TRUNK ARE HIGHLY COMPARABLE, WITH THE VAST DIFFERENCE IN THE LEG LENGTH. STUNTING IS A PERSONAL CONDITION IN WHICH AN INDIVIDUAL HAS A STANDING HEIGHT-FOR-AGE (HAZ) OF LESS THAN TWO STANDARD DEVIATIONS OF THE STANDARD CURVE MEDIAN. IT IS ASSOCIATED WITH INCREASED MORTALITY, MORBIDITY, AND FUNCTIONAL DEFICITS. THE PROCESS OF LOSING RELATIVE STATURE IS KNOWN AS LINEAR GROWTH RETARDATION, FIRST ATTRIBUTED TO CHRONIC PROTEIN DEFICIENCY, THEN TO AN ASSORTMENT OF MICRONUTRIENT DEFICIENCIES, AND MOST RECENTLY TO INFLAMMATION FROM UNHYGIENIC ENVIRONMENTAL CONDITIONS. PUBLIC HEALTH INTERVENTION TRIALS RESPONDING TO EACH OF THESE POSSIBILITIES HAVE FAILED TO PRODUCE TRUE REVERSAL RESPONSES MEASURED IN THE 10S OF CENTIMETERS. AS TO BIOLOGICAL INSIGHTS, THERE IS NO CONVENIENT WAY TO SEPARATE WEIGHT FROM LENGTH GROWTH WITH SONOGRAPHIC MONITORING, BUT A THIRD OF INFANTS CAN BE BORN STUNTED. NORMATIVE GROWTH (STANDARD CURVES) COMPETES WITH EPIGENETIC ADAPTATION (PROGRAMMING) AS THE BEACON FOR IN UTERO GROWTH. MAJOR INVESTMENTS INTO FIELD TRIALS ALLOW US TO DISCARD MULTIPLE MICRONUTRIENTS AND WATER/SANITATION/HYGIENE INTERVENTIONS AS MEASURES TO REVERSE ESTABLISHED STUNTING. THE PREPONDERANCE OF EVIDENCE IS AGAINST CATCH-UP GROWTH DURING PUBERTY. FUTURE PUBLICATIONS WILL BE IN THE CONCEPTUAL DOMAIN, RESOLVING METRICS, WHILE THE FULL RANGE OF STIMULI AND EXPOSURES IMPEDING GROWTH WILL BE ELUCIDATED. ADVANCES IN MEASUREMENT TECHNIQUES IN ANTHROPOMETRY AND IMMUNOLOGY AND ENDOCRINOLOGY WILL BE MOBILIZED TO THE LITERATURE.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
3  3208  49 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
4  4910  29 PAIN EXPOSURE ASSOCIATES WITH TELOMERE LENGTH EROSION IN VERY PRETERM INFANTS. VERY PRETERM (VPT) INFANTS (GESTATIONAL AGE < 32 WEEKS) REQUIRE LONG-LASTING HOSPITALIZATION IN THE NEONATAL INTENSIVE CARE UNIT (NICU), EVEN IN ABSENCE OF SEVERE MORBIDITIES. DURING NICU STAY, LIFE-SAVING INTERVENTIONS OCCUR AND INCLUDE INVASIVE AND PAINFUL SKIN-BREAKING PROCEDURES (NICU-RELATED STRESS), WHICH CONSTITUTE A MAJOR EARLY ADVERSE EXPERIENCE FOR VPT INFANTS. TELOMERES ARE REPEAT-SEQUENCE AT THE END OF CHROMOSOMES, WHICH SHORTEN WITH AGE AND ARE HIGHLY SUSCEPTIBLE TO LIFE ADVERSITIES: THE EXPOSURE TO EARLY ADVERSE EXPERIENCES IS ASSOCIATED WITH SHORTER TELOMERE LENGTH (TL). NONETHELESS, PREVIOUS RESEARCH DID NOT ASSESS LONGITUDINALLY THE ASSOCIATION BETWEEN NICU-RELATED STRESS AND TL IN VPT INFANTS. IN THE PRESENT STUDY, LEUKOCYTE TL WAS ASSESSED FROM CORD BLOOD AT BIRTH IN 46 VPT INFANTS AND IN A GROUP OF 31 FULL-TERM (FT) INFANTS, AS WELL AS AT NICU DISCHARGE IN VPTS ONLY. NICU-RELATED STRESS WAS MEASURED AS THE NUMBER OF SKIN-BREAKING PROCEDURES OCCURRING THROUGHOUT THE NICU STAY. A SIGNIFICANT DIFFERENCE EMERGED FOR TL BETWEEN VPT INFANTS AND FT COUNTERPARTS AT BIRTH. TL DECREASED FROM BIRTH TO DISCHARGE IN VPT INFANTS, ALTHOUGH THE CHANGE WAS NOT SIGNIFICANT IN THE GROUP AS A WHOLE. THE AMOUNT OF NICU-RELATED STRESS EMERGED AS THE PRIMARY PREDICTOR OF TL EROSION IN VPT INFANTS, EVEN CONTROLLING FOR NEONATAL AND CLINICAL CONFOUNDERS. FURTHERMORE, VPT INFANTS EXPOSED TO HIGH NICU-RELATED STRESS EXHIBITED A MARKED AND SIGNIFICANT DECREASE IN TL, WHEREAS VPT EXPOSED TO LOW NICU-RELATED STRESS EXHIBITED A NON-SIGNIFICANT INCREASE. THE PRESENT STUDY CONFIRMS PREVIOUS EVIDENCE OF LONGER TELOMERES IN VPT INFANTS AT BIRTH COMPARED TO FT CONTROLS. MOREOVER, NICU-RELATED STRESS EMERGED AS A KEY REGULATOR OF TL EROSION FROM BIRTH TO DISCHARGE IN VPT INFANTS. FUTURE RESEARCH IS WARRANTED TO FURTHER EXPLORE TL EROSION IN VPT INFANTS AND THE FACTORS ASSOCIATED WITH INDIVIDUAL DIFFERENCES IN NICU-RELATED STRESS SUSCEPTIBILITY AT THE EPIGENETIC LEVEL.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
5  3356  44 HISTONE H3 LYSINE 27 ACETYLATION PROFILE UNDERGOES TWO GLOBAL SHIFTS IN UNDERNOURISHED CHILDREN AND SUGGESTS ALTERED ONE-CARBON METABOLISM. BACKGROUND: STUNTING IS A CONDITION IN WHICH A CHILD DOES NOT REACH THEIR FULL GROWTH POTENTIAL DUE TO CHRONIC UNDERNUTRITION. IT ARISES DURING THE FIRST 2 YEARS OF A CHILD'S LIFE AND IS ASSOCIATED WITH DEVELOPMENTAL DEFICIENCIES AND LIFE-LONG HEALTH PROBLEMS. CURRENT INTERVENTIONS PROVIDE SOME BENEFIT, BUT NEW APPROACHES TO PREVENTION AND TREATMENT GROUNDED IN A MOLECULAR UNDERSTANDING OF STUNTING ARE NEEDED. EPIGENETIC ANALYSES ARE CRITICAL AS THEY CAN PROVIDE INSIGHT INTO HOW SIGNALS FROM A POOR ENVIRONMENT LEAD TO CHANGES IN CELL FUNCTION. RESULTS: HERE WE PROFILED HISTONE H3 ACETYLATION ON LYSINE 27 (H3K27AC) IN PERIPHERAL BLOOD MONONUCLEAR CELLS (PBMCS) OF 18-WEEK-OLD (N = 14) AND 1-YEAR-OLD CHILDREN (N = 22) LIVING IN AN URBAN SLUM IN DHAKA, BANGLADESH. WE SHOW THAT 18-WEEK-OLD CHILDREN DESTINED TO BECOME STUNTED HAVE ELEVATED LEVELS OF H3K27AC OVERALL, FUNCTIONAL ANALYSIS OF WHICH INDICATES ACTIVATION OF THE IMMUNE SYSTEM AND STRESS RESPONSE PATHWAYS AS A PRIMARY RESPONSE TO A POOR ENVIRONMENT WITH HIGH PATHOGEN LOAD. CONVERSELY, OVERT STUNTING AT 1-YEAR-OF AGE IS ASSOCIATED WITH GLOBALLY REDUCED H3K27AC THAT IS INDICATIVE OF METABOLIC REWIRING AND DOWNREGULATION OF THE IMMUNE SYSTEM AND DNA REPAIR PATHWAYS THAT ARE LIKELY SECONDARY RESPONSES TO CHRONIC EXPOSURE TO A POOR ENVIRONMENT WITH LIMITED NUTRIENTS. AMONG PROCESSES ALTERED IN 1-YEAR-OLD CHILDREN, WE IDENTIFIED ONE-CARBON METABOLISM, THE SIGNIFICANCE OF WHICH IS SUPPORTED BY INTEGRATIVE ANALYSIS WITH RESULTS FROM HISTONE H3 TRIMETHYLATION ON LYSINE 4 (H3K4ME3). TOGETHER, THESE RESULTS SUGGEST ALTERED ONE-CARBON METABOLISM IN THIS POPULATION OF STUNTED CHILDREN. CONCLUSIONS: THE EPIGENOMES OF STUNTED CHILDREN UNDERGO TWO GLOBAL CHANGES IN H3K27AC WITHIN THEIR FIRST YEAR OF LIFE, WHICH ARE ASSOCIATED WITH PROBABLE INITIAL HYPERACTIVE IMMUNE RESPONSES FOLLOWED BY REDUCED METABOLIC CAPACITY. LIMITATION OF ONE-CARBON METABOLITES MAY PLAY A KEY ROLE IN THE DEVELOPMENT OF STUNTING. TRIAL REGISTRATION CLINICALTRIALS.GOV NCT01375647.

6  3179  39 HAIR CORTISOL AS A HYPOTHALAMIC-PITUITARY-ADRENAL AXIS BIOMARKER IN PREGNANT WOMEN WITH ASTHMA: A RETROSPECTIVE OBSERVATIONAL STUDY. BACKGROUND: CORTISOL IS A HORMONE INVOLVED IN MANY PHYSIOLOGICAL FUNCTIONS INCLUDING FETAL MATURATION AND EPIGENETIC PROGRAMMING DURING PREGNANCY. THIS STUDY AIMED TO USE HAIR CORTISOL AS A BIOMARKER OF CHRONIC INHALED CORTICOSTEROID (ICS) EXPOSURE AND ASSESS THE POTENTIAL EFFECTS OF ASTHMA ON THE HYPOTHALAMIC-PITUITARY-ADRENAL (HPA) AXIS IN PREGNANT WOMEN. WE HYPOTHESIZED THAT PREGNANT WOMEN WITH ASTHMA TREATED WITH ICS WOULD EXHIBIT LOWER HAIR CORTISOL CONCENTRATIONS, INDICATIVE OF ADRENAL SUPPRESSION, COMPARED TO WOMEN WITH ASTHMA NOT USING ICS AND WOMEN WHO DO NOT HAVE ASTHMA. METHODS: WE PERFORMED AN OBSERVATIONAL RETROSPECTIVE COHORT STUDY. HAIR SAMPLES WERE ANALYZED FROM PREGNANT WOMEN WITH ASTHMA, WITH (N = 56) AND WITHOUT (N = 31) ICS TREATMENT, AND PREGNANT WOMEN WITHOUT ASTHMA (N = 31). HAIR SAMPLES WERE SEGMENTED BASED ON THE GROWTH RATE OF 1 CM/MONTH AND ANALYZED BY ENZYME IMMUNOASSAY TO PROVIDE CORTISOL CONCENTRATIONS CORRESPONDING TO PRECONCEPTION, TRIMESTERS 1-3, AND POSTPARTUM. HAIR CORTISOL CONCENTRATIONS WERE COMPARED WITHIN AND AMONG THE GROUPS USING NON-PARAMETRIC STATISTICAL TESTS. RESULTS: HAIR CORTISOL CONCENTRATIONS INCREASED ACROSS TRIMESTERS FOR ALL THREE GROUPS, BUT THIS INCREASE WAS DAMPENED IN WOMEN WITH ASTHMA (P = 0.03 FOR CONTROLS VS. ICS TREATED AND CONTROLS VS. NO ICS). ICS TREATED WOMEN TAKING MORE THAN FIVE DOSES PER WEEK HAD HAIR CORTISOL CONCENTRATIONS 47 % LOWER IN THIRD TRIMESTER THAN CONTROLS. LINEAR REGRESSION OF THE THIRD TRIMESTER HAIR CORTISOL RESULTS IDENTIFIED ASTHMA AS A SIGNIFICANT FACTOR WHEN COMPARING CONSISTENT ICS USE OR ASTHMA AS THE PREDICTOR (F(1, 25) = 9.7, P = 0.005, R(2) ADJ = 0.257). CONCLUSIONS: HAIR CORTISOL SUCCESSFULLY SHOWED THE EXPECTED CHANGE IN CORTISOL OVER THE COURSE OF PREGNANCY AND MAY BE A USEFUL BIOMARKER OF HPA AXIS FUNCTION IN PREGNANT WOMEN WITH ASTHMA. THE POTENTIAL IMPACT OF DECREASED MATERNAL CORTISOL IN WOMEN WITH ASTHMA ON PERINATAL OUTCOMES REMAINS TO BE DETERMINED.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
7  4504  35 MOTHER'S PRE-PREGNANCY BMI AND PLACENTAL CANDIDATE MIRNAS: FINDINGS FROM THE ENVIRONAGE BIRTH COHORT. THERE IS INCREASING EVIDENCE THAT THE PREDISPOSITION FOR DEVELOPMENT OF CHRONIC DISEASES ARISES AT THE EARLIEST TIMES OF LIFE. IN THIS CONTEXT, MATERNAL PRE-PREGNANCY WEIGHT MIGHT MODIFY FETAL METABOLISM AND THE CHILD'S PREDISPOSITION TO DEVELOP DISEASE LATER IN LIFE. THE AIM OF THIS STUDY IS TO INVESTIGATE THE ASSOCIATION BETWEEN MATERNAL PRE-PREGNANCY BODY MASS INDEX (BMI) AND MIRNA ALTERATIONS IN PLACENTAL TISSUE AT BIRTH. IN 211 MOTHER-NEWBORN PAIRS FROM THE ENVIRONAGE BIRTH COHORT, WE ASSESSED PLACENTAL EXPRESSION OF SEVEN MIRNAS IMPORTANT IN CRUCIAL CELLULAR PROCESSES IMPLICATED IN ADIPOGENESIS AND/OR OBESITY. MULTIPLE LINEAR REGRESSION MODELS WERE USED TO ADDRESS THE ASSOCIATIONS BETWEEN PRE-PREGNANCY BMI AND PLACENTAL CANDIDATE MIRNA EXPRESSION. MATERNAL PRE-PREGNANCY BMI AVERAGED (+/-SD) 23.9 (+/-4.1) KG/M(2). IN NEWBORN GIRLS (NOT IN BOYS) PLACENTAL MIR-20A, MIR-34A AND MIR-222 EXPRESSION WAS LOWER WITH HIGHER MATERNAL PRE-PREGNANCY BMI. IN ADDITION, THE ASSOCIATION BETWEEN MATERNAL PRE-PREGNANCY BMI AND PLACENTAL EXPRESSION OF THESE MIRNAS IN GIRLS WAS MODIFIED BY GESTATIONAL WEIGHT GAIN. THE LOWER EXPRESSION OF THESE MIRNAS IN PLACENTA IN ASSOCIATION WITH PRE-PREGNANCY BMI, WAS ONLY EVIDENT IN MOTHERS WITH LOW WEIGHT GAIN (<14 KG). THE PLACENTAL EXPRESSION OF MIR-20A, MIR-34A, MIR-146A, MIR-210 AND MIR-222 MAY PROVIDE A SEX-SPECIFIC BASIS FOR EPIGENETIC EFFECTS OF PRE-PREGNANCY BMI.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
8   649  49 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
9  5085  27 PILOT STUDY OF ABSOLUTE TELOMERE LENGTHS IN PRETERM INFANTS. BACKGROUND: ANNUALLY, APPROXIMATELY 15 MILLION BABIES ARE BORN PRETERM (<37 WEEKS GESTATIONAL AGE) GLOBALLY. IN THE NEONATAL INTENSIVE CARE UNIT (NICU) ENVIRONMENT, INFANTS ARE EXPOSED TO REPEATED STRESSFUL OR PAINFUL PROCEDURES AS PART OF ROUTINE LIFESAVING CARE. THESE PROCEDURES HAVE BEEN ASSOCIATED WITH EPIGENETIC ALTERATIONS THAT MAY LEAD TO AN INCREASED RISK OF NEURODEVELOPMENTAL DISORDERS. TELOMERE LENGTH HAS BEEN NEGATIVELY ASSOCIATED WITH ADVERSE LIFE EXPERIENCES IN STUDIES OF ADULTS. OBJECTIVES: THIS PILOT STUDY AIMED TO DESCRIBE TELOMERE LENGTH IN A SAMPLE OF PRETERM INFANTS AT NICU DISCHARGE AND EXAMINE ANY ASSOCIATIONS WITH PAIN, FEEDING METHOD, AND NEURODEVELOPMENT. METHODS: THIS DESCRIPTIVE PILOT STUDY SAMPLE INCLUDES BASELINE ABSOLUTE TELOMERE LENGTH (ATL) OF 36 PRETERM INFANTS IMMEDIATELY PRIOR TO DISCHARGE. QUANTITATIVE POLYMERASE CHAIN REACTION WAS USED TO DETERMINE ATL. INFANT DEMOGRAPHICS, PAIN/STRESS, TYPE OF FEEDING, ANTIBIOTIC USE, NEURODEVELOPMENT, AND BUCCAL SWAB DATA WERE COLLECTED. DESCRIPTIVE DATA ANALYSIS WAS USED TO DESCRIBE THE TELOMERE LENGTH USING GRAPHS. RESULTS: AMONG OUR PRETERM INFANT SAMPLES, THE MEAN ATL WAS FAR GREATER THAN THE AVERAGE ADULT TELOMERE LENGTH. ALTHOUGH NO SIGNIFICANT ASSOCIATIONS WERE FOUND BETWEEN ATL AND PAIN, FEEDING METHOD, AND NEURODEVELOPMENT, A TREND BETWEEN SEX WAS NOTED WHERE MALE TELOMERE LENGTHS WERE SHORTER THAN FEMALES AS THEY AGED. DISCUSSION: THIS IS ONE OF FEW STUDIES TO EVALUATE PRETERM INFANT TELOMERE LENGTH. ALTHOUGH OTHER RESEARCHERS HAVE USED RELATIVE TELOMERE LENGTH, WE USED THE MORE ACCURATE ATL. WE FOUND NONSIGNIFICANT SHORTER TELOMERE LENGTHS AMONG MALES. ADDITIONAL LARGE-SCALE, LONGITUDINAL STUDIES ARE NEEDED TO BETTER IDENTIFY THE PREDICTORS OF TELOMERE LENGTH AT THE TIME OF DISCHARGE FROM NICU.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
10  4066  42 MATERNAL AND PATERNAL PERICONCEPTIONAL NUTRITION AS AN INDICATOR OF OFFSPRING METABOLIC SYNDROME RISK IN LATER LIFE THROUGH EPIGENETIC IMPRINTING: A SYSTEMATIC REVIEW. AIMS: THIS REVIEW EXAMINED WHETHER MATERNAL AND PATERNAL PERICONCEPTIONAL NUTRITION EFFECTS AN OFFSPRING'S LIKELIHOOD OF DEVELOPING CHRONIC METABOLIC RELATED CONDITIONS DUE TO EPIGENETIC IMPRINTING. METHODS: A LITERATURE SEARCH WAS CONDUCTED IN MULTIPLE SCIENCE DATABASES AND LIMITED TO STUDIES PUBLISHED AFTER 2012, IN ENGLISH LANGUAGE AND PEER REVIEWED. THE DATA FROM SELECTED ARTICLES WERE EXTRACTED AND A QUALITATIVE APPROACH WAS EMPLOYED DUE TO HETEROGENEITY OF RESULTS. RESULTS: NEWBORNS FROM OBESE FATHERS SHOWED ALTERED METHYLATION OVERALL AND SIGNIFICANT HYPOMETHYLATION AT THE INSULIN-LIKE GROWTH FACTOR 2 (IGF2) GENE. HIGH MATERNAL PRE-PREGNANCY BODY MASS INDEX (BMI) WAS ASSOCIATED WITH ALTERED OFFSPRING DNA METHYLATION LEVELS AND GESTATIONAL DIABETES MELLITUS INDUCED SIGNIFICANTLY INCREASED METHYLATION LEVELS IN OFFSPRING. GESTATIONAL WEIGHT GAIN WAS NOT ASSOCIATED WITH DIFFERENTIALLY METHYLATED CORD BLOOD. BIRTH WEIGHT WAS HIGHER IN OFFSPRING EXPOSED TO FAMINE IN EARLY GESTATION. OFFSPRING BORN POST MATERNAL BARIATRIC SURGERY SHOWED A LOWER PERCENTAGE OF BODY FAT AND IMPROVED FASTING INSULIN LEVELS COMPARED TO SIBLINGS BORN PRE-MATERNAL BARIATRIC SURGERY. CONCLUSIONS: THE AVAILABLE EVIDENCE SUGGESTS THAT POOR MATERNAL AND PATERNAL PERICONCEPTIONAL NUTRITION CAN INCREASE THE RISK OF METABOLIC SYNDROME IN OFFSPRING, THROUGH EPIGENETIC IMPRINTING. POTENTIAL PARENTS SHOULD BE ADVISED THAT MAINTAINING A HEALTHY DIET AND BMI IS LIKELY TO REDUCE THE RISK OF METABOLIC SYNDROME IN OFFSPRING.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
11   518  42 ASSOCIATIONS BETWEEN ANTIBIOTIC EXPOSURE DURING PREGNANCY, BIRTH WEIGHT AND ABERRANT METHYLATION AT IMPRINTED GENES AMONG OFFSPRING. OBJECTIVES: LOW BIRTH WEIGHT (LBW) HAS BEEN ASSOCIATED WITH COMMON ADULT-ONSET CHRONIC DISEASES, INCLUDING OBESITY, CARDIOVASCULAR DISEASE, TYPE II DIABETES AND SOME CANCERS. THE ETIOLOGY OF LBW IS MULTI-FACTORIAL. HOWEVER, RECENT EVIDENCE SUGGESTS EXPOSURE TO ANTIBIOTICS MAY ALSO INCREASE THE RISK OF LBW. THE MECHANISMS UNDERLYING THIS ASSOCIATION ARE UNKNOWN, ALTHOUGH EPIGENETIC MECHANISMS ARE HYPOTHESIZED. IN THIS STUDY, WE EVALUATED THE ASSOCIATION BETWEEN MATERNAL ANTIBIOTIC USE AND LBW AND EXAMINED THE POTENTIAL ROLE OF ALTERED DNA METHYLATION THAT CONTROLS GROWTH REGULATORY IMPRINTED GENES IN THESE ASSOCIATIONS. METHODS: BETWEEN 2009-2011, 397 PREGNANT WOMEN WERE ENROLLED AND FOLLOWED UNTIL DELIVERY. PRENATAL ANTIBIOTIC USE WAS ASCERTAINED THROUGH MATERNAL SELF-REPORT. IMPRINTED GENES METHYLATION LEVELS WERE MEASURED AT DIFFERENTIALLY METHYLATED REGIONS (DMRS) USING BISULFITE PYROSEQUENCING. GENERALIZED LINEAR MODELS WERE USED TO EXAMINE ASSOCIATIONS AMONG ANTIBIOTIC USE, BIRTH WEIGHT AND DMR METHYLATION FRACTIONS. RESULTS: AFTER ADJUSTING FOR INFANT GENDER, RACE/ETHNICITY, MATERNAL BODY MASS INDEX, DELIVERY ROUTE, GESTATIONAL WEIGHT GAIN, GESTATIONAL AGE AT DELIVERY, FOLIC ACID INTAKE, PHYSICAL ACTIVITY, MATERNAL SMOKING AND PARITY, ANTIBIOTIC USE DURING PREGNANCY WAS ASSOCIATED WITH 138 G LOWER BIRTH WEIGHT COMPARED WITH NON-ANTIBIOTIC USE (BETA-COEFFICIENT=-132.99, S.E.=50.70, P=0.008). THESE ASSOCIATIONS WERE STRONGEST IN NEWBORNS OF WOMEN WHO REPORTED ANTIBIOTIC USE OTHER THAN PENICILLINS (BETA-COEFFICIENT=-135.57, S.E.=57.38, P=0.02). METHYLATION AT FIVE DMRS, IGF2 (P=0.05), H19 (P=0.15), PLAGL1 (P=0.01), MEG3 (P=0.006) AND PEG3 (P=0.08), WAS ASSOCIATED WITH MATERNAL ANTIBIOTIC USE; AMONG THESE, ONLY METHYLATION AT THE PLAGL1 DMR WAS ALSO ASSOCIATED WITH BIRTH WEIGHT. CONCLUSION: WE REPORT AN INVERSE ASSOCIATION BETWEEN IN UTERO EXPOSURE TO ANTIBIOTICS AND LOWER INFANT BIRTH WEIGHT AND PROVIDE THE FIRST EMPIRICAL EVIDENCE SUPPORTING IMPRINTED GENE PLASTICITY IN THESE ASSOCIATIONS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
12  1746  30 EARLY LIFE ADVERSITY, PUBERTAL TIMING, AND EPIGENETIC AGE ACCELERATION IN ADULTHOOD. BACKGROUND: GIVEN ASSOCIATIONS LINKING EARLY LIFE ADVERSITY, PUBERTAL TIMING, AND BIOLOGICAL AGING, WE EXAMINED THE DIRECT AND INDIRECT EFFECTS OF EARLY LIFE TRAUMA ON ADULT BIOLOGICAL AGING (VIA AGE OF MENARCHE). METHODS: PARTICIPANTS WERE PREMENOPAUSAL WOMEN (N = 183). PATH MODELS EVALUATED WHETHER EARLY LIFE TRAUMA PREDICTED EARLY PUBERTAL TIMING AND THEREBY, ADULT EPIGENETIC AGE ACCELERATION (INDEXED VIA FOUR EPIGENETIC CLOCKS: HORVATH DNAM AGE, HANNUM DNAM AGE, DNAM PHENOAGE, AND DNAM GRIMAGE). SECONDARY ANALYSES EXPLORED THE EFFECTS OF TYPE OF TRAUMA (ABUSE AND NEGLECT) AND ADULT CHRONIC STRESS STATUS (CAREGIVER OF CHILD WITH AUTISM AND NON-CAREGIVER). RESULTS: EARLY LIFE TRAUMA AND EARLIER AGE AT MENARCHE INDEPENDENTLY PREDICTED ACCELERATED AGING BASED ON ONE OF THE FOUR EPIGENETIC CLOCKS, DNAM GRIMAGE, THOUGH EARLY LIFE TRAUMA WAS NOT ASSOCIATED WITH AGE OF MENARCHE. CHILDHOOD ABUSE, BUT NOT NEGLECT, PREDICTED FASTER EPIGENETIC AGING; RESULTS DID NOT DIFFER BY CHRONIC STRESS STATUS. CONCLUSIONS: EARLY TRAUMA AND EARLY MENARCHE APPEAR TO EXERT INDEPENDENT EFFECTS ON DNAM GRIMAGE, WHICH HAS BEEN SHOWN TO BE THE STRONGEST EPIGENETIC PREDICTOR OF MORTALITY RISK. THIS STUDY IDENTIFIES A POTENTIAL CORRELATE OR DETERMINANT OF ACCELERATED EPIGENETIC AGING-MENARCHEAL AGE. FUTURE RESEARCH SHOULD ADDRESS THE LIMITATIONS OF THIS STUDY BY USING RACIALLY DIVERSE SAMPLES.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
13  5179  54 PREGNANCY: AN UNDERUTILIZED WINDOW OF OPPORTUNITY TO IMPROVE LONG-TERM MATERNAL AND INFANT HEALTH-AN APPEAL FOR CONTINUOUS FAMILY CARE AND INTERDISCIPLINARY COMMUNICATION. PHYSIOLOGIC ADAPTATIONS DURING PREGNANCY UNMASK A WOMAN'S PREDISPOSITION TO DISEASES. COMPLICATIONS ARE INCREASINGLY PREDICTED BY FIRST-TRIMESTER ALGORITHMS, AMPLIFY A PRE-EXISTING MATERNAL PHENOTYPE AND ACCELERATE RISKS FOR CHRONIC DISEASES IN THE OFFSPRING UP TO ADULTHOOD (BARKER HYPOTHESIS). RECENT EVIDENCE SUGGESTS THAT VICE VERSA, PREGNANCY DISEASES ALSO INDICATE MATERNAL AND EVEN GRANDPARENT'S RISKS FOR CHRONIC DISEASES (REVERSE BARKER HYPOTHESIS). PUB-MED AND EMBASE WERE REVIEWED FOR MESH TERMS "FETAL PROGRAMMING" AND "PREGNANCY COMPLICATIONS COMBINED WITH MATERNAL DISEASE" UNTIL JANUARY 2017. STUDIES LINKING PREGNANCY COMPLICATIONS TO FUTURE CARDIOVASCULAR, METABOLIC, AND THROMBOTIC RISKS FOR MOTHER AND OFFSPRING WERE REVIEWED. WOMEN WITH A HISTORY OF MISCARRIAGE, FETAL GROWTH RESTRICTION, PREECLAMPSIA, PRETERM DELIVERY, OBESITY, EXCESSIVE GESTATIONAL WEIGHT GAIN, GESTATIONAL DIABETES, SUBFERTILITY, AND THROMBOPHILIA MORE FREQUENTLY DEMONSTRATE WITH ECHOCARDIOGRAPHIC ABNORMALITIES, HIGHER FASTING INSULIN, DEVIATING LIPIDS OR CLOTTING FACTORS AND SHOW DEFECTIVE ENDOTHELIAL FUNCTION. THROMBOPHILIA HINTS TO THROMBOTIC RISKS IN LATER LIFE. PREGNANCY ABNORMALITIES CORRELATE WITH FUTURE CARDIOVASCULAR AND METABOLIC COMPLICATIONS AND EARLIER MORTALITY. CONVERSELY, WOMEN WITH A NORMAL PREGNANCY HAVE LOWER RATES OF SUBSEQUENT DISEASES THAN THE GENERAL FEMALE POPULATION CREATING THE TERM: "PREGNANCY AS A WINDOW FOR FUTURE HEALTH." ALTHOUGH THE PLACENTA WORKS AS A GATEKEEPER, MANY PREGNANCY COMPLICATIONS MAY LEAD TO SICKNESS AND EARLIER DEATH IN LATER LIFE WHEN THE CHILD BECOMES AN ADULT. THE EPIGENETIC MECHANISMS AND THE MISMATCH BETWEEN PRE- AND POSTNATAL LIFE HAVE CREATED THE TERM "FETAL ORIGIN OF ADULT DISEASE." UP TO NOW, THE IMPACT OF CARDIOVASCULAR, METABOLIC, OR THROMBOTIC RISK PROFILES HAS BEEN INVESTIGATED SEPARATELY FOR MOTHER AND CHILD. IN THIS MANUSCRIPT, WE STRIVE TO ILLUSTRATE THE CONSEQUENCES FOR BOTH, FETUS AND MOTHER WITHIN A COHESIVE PERSPECTIVE AND THUS TRY TO DEMONSTRATE THE COMPLEX INTERRELATIONSHIP OF GENETICS AND EPIGENETICS FOR LONG-TERM HEALTH OF SOCIETIES AND FUTURE GENERATIONS. MATERNAL-FETAL MEDICINE SPECIALISTS SHOULD HAVE A KEY ROLE IN THE PREVENTION OF NON-COMMUNICABLE DISEASES BY IMPLEMENTING A FRAMEWORK FOR PATIENT CONSULTATION AND INTERDISCIPLINARY NETWORKS. HEALTH-CARE PROVIDERS AND POLICY MAKERS SHOULD INCREASINGLY INVEST IN A STRATIFIED PRIMARY PREVENTION AND FOLLOW-UP TO REDUCE THE INCREASING NUMBER OF MANIFEST CARDIOVASCULAR AND METABOLIC DISEASES AND TO PREVENT WASTE OF HEALTH-CARE RESOURCES.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
14  2605  25 EPIGENETICS-A POTENTIAL MEDIATOR BETWEEN AIR POLLUTION AND PRETERM BIRTH. PRETERM BIRTH IS A MAJOR CAUSE OF INFANT MORBIDITY AND MORTALITY AND A POTENTIAL RISK FACTOR FOR ADULT CHRONIC DISEASE. WITH OVER 15 MILLION INFANTS BORN PRETERM WORLDWIDE EACH YEAR, PRETERM BIRTH POSES A GLOBAL HEALTH CONCERN. THERE IS A POSSIBLE ASSOCIATION BETWEEN AIR POLLUTION AND PRETERM BIRTH, THOUGH STUDIES HAVE BEEN INCONSISTENT, LIKELY DUE TO VARIATION IN STUDY DESIGN. HOW AIR POLLUTION INDUCES HEALTH EFFECTS IS UNCERTAIN; HOWEVER, STUDIES HAVE REPEATEDLY DEMONSTRATED THE EFFECTS OF AIR POLLUTION ON EPIGENETIC MODIFICATIONS. MORE RECENT EVIDENCE SUGGESTS THAT EPIGENETICS MAY, IN TURN, BE LINKED TO PRETERM BIRTH. DISCOVERY OF ENVIRONMENTALLY MODIFIABLE EPIGENETIC PROCESSES CONNECTED TO PRETERM BIRTH MAY HELP TO IDENTIFY WOMEN AT RISK OF PRETERM BIRTH, AND ULTIMATELY LEAD TO DEVELOPMENT OF NEW PRETERM BIRTH PREVENTION MEASURES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
15  1960  47 EPIGENETIC AGING IN CHILDREN FROM A SMALL-SCALE FARMING SOCIETY IN THE CONGO BASIN: ASSOCIATIONS WITH CHILD GROWTH AND FAMILY CONFLICT. DEVELOPMENTAL ENVIRONMENTS INFLUENCE INDIVIDUALS' LONG-TERM HEALTH TRAJECTORIES, AND THERE IS INCREASING EMPHASIS ON UNDERSTANDING THE BIOLOGICAL PATHWAYS THROUGH WHICH THIS OCCURS. EPIGENETIC AGING EVALUATES DNA METHYLATION AT A SUITE OF DISTINCT CPG SITES IN THE GENOME, AND EPIGENETIC AGE ACCELERATION (EAA) IS LINKED TO HEIGHTENED CHRONIC MORBIDITY AND MORTALITY RISKS IN ADULTS. CONSEQUENTLY, EAA PROVIDES INSIGHTS ON TRAJECTORIES OF BIOLOGICAL AGING, WHICH EARLY LIFE EXPERIENCES MAY HELP SHAPE. HOWEVER, FEW STUDIES HAVE MEASURED CORRELATES OF CHILDREN'S EPIGENETIC AGING, ESPECIALLY OUTSIDE OF THE U.S. AND EUROPE. IN PARTICULAR, LITTLE IS KNOWN ABOUT HOW CHILDREN'S GROWTH AND DEVELOPMENT RELATE TO EAA IN ECOLOGIES IN WHICH ENERGETIC AND PATHOGENIC STRESSORS ARE COMMONPLACE. WE STUDIED EAA FROM DRIED BLOOD SPOTS AMONG BONDONGO CHILDREN (N = 54) RESIDING IN A SMALL-SCALE, FISHER-FARMER SOCIETY IN A REMOTE REGION OF THE REPUBLIC OF THE CONGO. HERE, INFECTIOUS DISEASE BURDENS AND THEIR RESULTANT ENERGY DEMANDS ARE HIGH. CHILDREN WHO WERE HEAVIER FOR HEIGHT OR TALLER FOR AGE, RESPECTIVELY, EXHIBITED GREATER EAA, INCLUDING INTRINSIC EAA, WHICH IS CONSIDERED TO MEASURE EAA INTERNAL TO CELLS. FURTHERMORE, WE FOUND THAT CHILDREN IN FAMILIES WITH MORE CONFLICT BETWEEN PARENTS HAD GREATER INTRINSIC EAA. THESE RESULTS SUGGEST THAT IN CONTEXTS IN WHICH LIMITED ENERGY MUST BE ALLOCATED TO COMPETING DEMANDS, MORE INVESTMENT IN GROWTH MAY COINCIDE WITH GREATER EAA, WHICH PARALLELS FINDINGS IN EUROPEAN CHILDREN WHO DO NOT FACE SIMILAR ENERGETIC CONSTRAINTS. OUR FINDINGS ALSO INDICATE THAT ASSOCIATIONS BETWEEN ADVERSE FAMILY ENVIRONMENTS AND GREATER INTRINSIC EAA WERE NONETHELESS OBSERVABLE BUT ONLY AFTER ADJUSTMENT FOR COVARIATES RELEVANT TO THE ENERGETICALLY AND IMMUNOLOGICALLY DEMANDING NATURE OF THE LOCAL ECOLOGY.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
16  3145  34 GLOBAL POPULATION VARIATION IN PLACENTAL SIZE AND STRUCTURE: EVIDENCE FROM CEBU, PHILIPPINES. INTRODUCTION: PLACENTAL MORPHOLOGY INFLUENCES THE INTRAUTERINE ENVIRONMENT AND FETAL GROWTH, WHICH HELP SET LIFE-COURSE HEALTH TRAJECTORIES ACROSS GENERATIONS. LITTLE IS KNOWN ABOUT PLACENTAL CHARACTERISTICS IN POPULATIONS WITH CHRONIC NUTRITIONAL INSUFFICIENCY WHERE BIRTH WEIGHTS TEND TO BE LOWER, AND HOW THESE RELATIONSHIPS BETWEEN BIRTH AND PLACENTAL WEIGHTS VARY ACROSS POPULATIONS. METHODS: WE COLLECTED WEIGHTS AND STEREOLOGICALLY-DETERMINED VILLOUS MASS AND SURFACE AREA OF 21 PLACENTAS FROM OFFSPRING OF WOMEN ENROLLED IN A BIRTH COHORT STUDY IN METROPOLITAN CEBU, PHILIPPINES, A LOW-INCOME POPULATION. WE IDENTIFIED 15 SAMPLES FROM OTHER GLOBAL POPULATIONS RANGING FROM LOW TO HIGH INCOME THAT HAD SIMILAR DATA TO OURS TO ASSESS PATTERNS OF VARIATION BETWEEN BIRTH AND PLACENTAL WEIGHTS AND MICROSCOPIC CHARACTERISTICS. WE RANKED THE POPULATION SAMPLES IN ORDER FOR EACH CHARACTERISTIC. RESULTS: MEAN BIRTH WEIGHT IN CEBU WAS 3162 +/- 80 G (RANKED 9/16) AND PLACENTAL WEIGHT WAS 454 +/- 32 G (RANKED 12/16). BIRTH:PLACENTAL WEIGHT RATIO WAS 7.0 (RANKED 3/16). AVERAGE VILLOUS SURFACE AREA FOR CEBU PLACENTAS WAS 6.5 M(2) (RANKED 9/12); BIRTH WEIGHT:VILLOUS SURFACE AREA WAS 0.048 G/M(2) (RANKED 4/12). DISCUSSION: PLACENTAS FROM CEBU PRODUCED HEAVIER NEONATES PER UNITS OF PLACENTAL WEIGHT AND VILLOUS SURFACE AREA THAN MOST OTHER POPULATIONS, DESPITE LOWER VILLOUS SURFACE AREAS AND LESS COMPLEX SURFACE-TO-VOLUME TOPOGRAPHY. THIS RANGE OF PLACENTAL EFFICIENCY SPURS QUESTIONS ABOUT THE MECHANISMS BY WHICH PLACENTAL MORPHOLOGY OPTIMIZES EFFICIENCY IN DIFFERENT ENVIRONMENTAL CONTEXTS DURING GESTATION. PLACENTAL VARIATION BOTH WITHIN AND ACROSS POPULATIONS IS LIKELY DUE TO MANY INTERSECTING ENVIRONMENTAL, METABOLIC, AND (EPI)GENETIC FACTORS THAT WILL REQUIRE ADDITIONAL RESEARCH TO CLARIFY.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
17  4065  48 MATERNAL AND GESTATIONAL INFLUENCES ON CHILDHOOD BLOOD PRESSURE. EXPOSURES THAT CONTRIBUTE TO A SUB-OPTIMAL INTRAUTERINE ENVIRONMENT CAN HAVE AN EFFECT ON THE DEVELOPING FETUS. IMPAIRED FETAL GROWTH THAT RESULTS IN LOW BIRTH WEIGHT IS AN ESTABLISHED RISK FACTOR FOR CARDIO-METABOLIC DISORDERS LATER IN LIFE. RECENT EPIDEMIOLOGIC AND PROSPECTIVE COHORT STUDIES THAT INCLUDE THE MATERNAL AND GESTATIONAL PERIOD HAVE IDENTIFIED MATERNAL AND GESTATIONAL CONDITIONS THAT CONFER INCREASED RISK FOR SUBSEQUENT CARDIO-METABOLIC DISORDERS IN THE ABSENCE OF LOW BIRTH WEIGHT. MATERNAL PRE-CONCEPTION HEALTH STATUS, INCLUDING CHRONIC OBESITY AND TYPE 2 DIABETES, INCREASE RISK FOR CHILDHOOD OBESITY AND OBESITY-RELATED HIGHER BLOOD PRESSURE (BP) IN CHILD OFFSPRING. MATERNAL GESTATIONAL EXPOSURES, INCLUDING GESTATIONAL DIABETES, GESTATIONAL HYPERTENSION, AND PREECLAMPSIA, ARE ASSOCIATED WITH HIGHER BP IN OFFSPRING. OTHER MATERNAL EXPOSURES SUCH AS CIGARETTE SMOKE AND AIR POLLUTION ALSO INCREASE RISK FOR HIGHER BP IN CHILD OFFSPRING. RECENT, BUT LIMITED, DATA INDICATE THAT ASSISTED REPRODUCTIVE TECHNOLOGIES CAN BE ASSOCIATED WITH HYPERTENSION IN CHILDHOOD, DESPITE OTHERWISE NORMAL GESTATION AND HEALTHY NEWBORN. GESTATIONAL EXPOSURES ASSOCIATED WITH HIGHER BP IN CHILDHOOD CAN BE RELATED TO FAMILIAL LIFESTYLE FACTORS, GENETICS, OR EPIGENETIC MODIFICATION OF FETAL DEOXYRIBONUCLEIC ACID (DNA). THESE FACTORS, OR COMBINATION OF FACTORS, AS WELL AS OTHER ADVERSE INTRAUTERINE CONDITIONS, COULD INDUCE FETAL PROGRAMING LEADING TO HEALTH CONSEQUENCES IN LATER LIFE. CURRENT AND DEVELOPING RESEARCH WILL PROVIDE ADDITIONAL INSIGHTS ON GESTATIONAL EXPOSURES AND FETAL ADJUSTMENTS THAT INCREASE RISK FOR HIGHER BP LEVELS IN CHILDHOOD.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
18  6625  42 UNDERSTANDING RACIAL DISPARITIES OF PRETERM BIRTH THROUGH THE PLACENTA. THE RACIAL DISPARITY ASSOCIATED WITH PRETERM BIRTH IS A PUBLIC HEALTH CONCERN IN THE UNITED STATES. THE PLACENTA IS THE PRINCIPAL METABOLIC, RESPIRATORY, AND ENDOCRINE ORGAN OF THE FETUS AND A KEY ROUTE BY WHICH ENVIRONMENTAL EXPOSURES ARE TRANSMITTED FROM MOTHER TO OFFSPRING. AVAILABLE AT EVERY DELIVERY, IT MAY SERVE AS A MARKER OF DIFFERENCES IN PRENATAL EXPOSURES THAT MANIFEST DIFFERENTLY BY RACE. RECENTLY, WE DESCRIBED DIFFERENCES IN PLACENTAL PATHOLOGY BETWEEN AFRICAN-AMERICAN AND WHITE PRETERM BIRTHS: THE PREVALENCE OF CHRONIC INFLAMMATION WAS HIGHER AMONG AFRICAN-AMERICAN WOMEN'S PLACENTAS COMPARED WITH THOSE OF WHITE WOMEN. SIMILARLY, RACIAL DIFFERENCES HAVE BEEN SHOWN IN PLACENTAL MALPERFUSION AND PLACENTAL WEIGHT. SOCIAL DETERMINANTS SUCH AS POVERTY AND STRESS FROM DISCRIMINATION HAVE BEEN IMPLICATED IN RACIAL DISPARITIES IN PRETERM BIRTH. TO DATE, HOWEVER, THE UNDERLYING BIOLOGICAL MECHANISMS, WHETHER THROUGH INFLAMMATORY, OXIDATIVE STRESS, OR OTHER PATHWAYS INVOLVING EPIGENETIC PROGRAMMING, REMAIN LARGELY UNKNOWN. THE PLACENTA, COMPLEMENTED BY MATERNAL AND UMBILICAL CORD BLOOD BIOMARKERS, MAY PROVIDE IMPORTANT INFORMATION ON THE PERINATAL ENVIRONMENT THAT EXPLAINS THE ORIGINS OF RACIAL DISPARITIES IN PRETERM BIRTH RATES AND SUBSEQUENT HEALTH OUTCOMES. THIS ARTICLE REVIEWS EXISTING LITERATURE AND CURRENT RESEARCH GAPS. OPPORTUNITIES ARE DISCUSSED FOR FUTURE PLACENTAL RESEARCH THAT MAY REVEAL NOVEL MECHANISMS LEADING TO THE DEVELOPMENT OF NEW APPROACHES IN THE PREVENTION AND MANAGEMENT OF PRETERM BIRTH AND ITS OUTCOMES.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
19  5962  46 TELOMERES, OXIDATIVE STRESS, AND TIMING FOR SPONTANEOUS TERM AND PRETERM LABOR. TELOMERES ARE NUCLEOPROTEIN COMPLEXES LOCATED AT THE DISTAL ENDS OF CHROMOSOMES. IN ADULTS, PROGRESSIVE TELOMERE SHORTENING OCCURS THROUGHOUT THE LIFETIME AND IS THOUGHT TO CONTRIBUTE TO PROGRESSIVE AGING, PHYSIOLOGICAL SENESCENCE, MULTIORGAN DYSFUNCTION, AND ULTIMATELY, DEATH. AS DISCUSSED IN THIS REVIEW, MULTIPLE LINES OF EVIDENCE PROVIDE SUPPORT FOR THE BIOLOGICAL PLAUSIBILITY THAT A TELOMERE-BASED CLOCK MECHANISM ALSO DETERMINES THE LENGTH OF GESTATION, LEADING TO THE ONSET OF LABOR (PARTURITION). AFTER TELOMERE EXPANSION AT THE BEGINNING OF PREGNANCY, THE TELOMERE LENGTHS IN THE GESTATIONAL TISSUES (IE, THE PLACENTA AND FETAL MEMBRANES) PROGRESSIVELY SHORTEN THROUGHOUT THE REMAINDER OF PREGNANCY. THE RATE OF TELOMERE SHORTENING CAN BE ACCELERATED BY CONDITIONS THAT AFFECT THE MOTHER AND RESULT IN OXIDATIVE STRESS. PRETERM BIRTHS IN THE UNITED STATES ARE ASSOCIATED WITH MULTIPLE RISK FACTORS THAT ARE LINKED WITH INCREASED OXIDATIVE STRESS. ANTIOXIDANT VITAMINS (IE, VITAMINS E AND C) MITIGATE THE EFFECTS OF OXIDATIVE STRESS AND DELAY OR PREVENT TELOMERE SHORTENING. CLINICAL TRIALS WITH VITAMINS E AND C AND WITH MULTIVITAMINS STARTED DURING THE PERICONCEPTION PERIOD HAVE BEEN ASSOCIATED WITH REDUCED RATES OF PRETERM BIRTHS. IN THE UNITED STATES, AFRICAN-AMERICAN WOMEN HAVE A 2-3-FOLD HIGHER RATE OF PRETERM BIRTH. AFRICAN-AMERICAN WOMEN HAVE MULTIPLE RISK FACTORS FOR PREMATURE BIRTH, ALL OF WHICH ARE DISTINCT AND POTENTIALLY ADDITIVE WITH REGARD TO EPIGENETIC TELOMERE SHORTENING. THE "WEATHERING EFFECT" IS THE HYPOTHESIS TO EXPLAIN THE INCREASED RATES OF CHRONIC ILLNESS, DISABILITIES, AND EARLY DEATH OBSERVED IN AFRICAN-AMERICANS. WITH REGARD TO PREGNANCY, ACCELERATED WEATHERING WITH THE ASSOCIATED TELOMERE SHORTENING IN THE GESTATIONAL TISSUES WOULD NOT ONLY EXPLAIN THE PRETERM BIRTH DISPARITY BUT COULD ALSO EXPLAIN WHY HIGHLY EDUCATED, AFFLUENT AFRICAN-AMERICAN WOMEN CONTINUE TO HAVE AN INCREASED RATE OF PRETERM BIRTH. THESE STUDIES SUGGEST THAT THE RACIAL DISPARITIES IN PRETERM BIRTH ARE POTENTIALLY MEDIATED BY TELOMERE SHORTENING PRODUCED BY LIFETIME OR EVEN GENERATIONAL EXPOSURE TO THE EFFECTS OF SYSTEMIC RACISM AND SOCIOECONOMIC MARGINALIZATION. IN CONCLUSION, THIS REVIEW PRESENTS MULTIPLE LINES OF EVIDENCE SUPPORTING A NOVEL HYPOTHESIS REGARDING THE BIOLOGICAL CLOCK MECHANISM THAT DETERMINES THE LENGTH OF PREGNANCY, AND IT OPENS THE POSSIBILITY OF NEW APPROACHES TO PREVENT OR REDUCE THE RATE OF SPONTANEOUS PRETERM BIRTH.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
20   521  39 ASSOCIATIONS BETWEEN MATERNAL PSYCHOSOCIAL STRESS, DNA METHYLATION, AND NEWBORN BIRTH WEIGHT IDENTIFIED BY INVESTIGATING METHYLATION AT INDIVIDUAL, REGIONAL, AND GENOME LEVELS. STRESS IS KNOWN TO AFFECT HEALTH THROUGHOUT LIFE AND INTO FUTURE GENERATIONS, BUT THE UNDERLYING MOLECULAR MECHANISMS ARE UNKNOWN. WE TESTED THE HYPOTHESIS THAT MATERNAL PSYCHOSOCIAL STRESS INFLUENCES DNA METHYLATION (DNAM), WHICH IN TURN IMPACTS NEWBORN HEALTH OUTCOMES. SPECIFICALLY, WE ANALYZED DNAM AT INDIVIDUAL, REGIONAL, AND GENOME-WIDE LEVELS TO TEST FOR ASSOCIATIONS WITH MATERNAL STRESS AND NEWBORN BIRTH WEIGHT. MATERNAL VENOUS BLOOD AND NEWBORN CORD BLOOD (N = 24 AND 22, RESPECTIVELY) WERE ASSAYED FOR METHYLATION AT APPROXIMATELY 450,000 CPG SITES. METHYLATION WAS ANALYZED BY EXAMINING CPG SITES INDIVIDUALLY IN AN EPIGENOME-WIDE ASSOCIATION STUDY (EWAS), AS REGIONAL GROUPS USING VARIABLY METHYLATED REGION (VMR) ANALYSIS IN MATERNAL BLOOD ONLY, AND THROUGH THE EPIGENOME-WIDE MEASURES USING GENOME-WIDE MEAN METHYLATION (GMM), HORVATH'S EPIGENETIC CLOCK, AND MITOTIC AGE. THESE METHYLATION MEASURES WERE TESTED FOR ASSOCIATION WITH THREE MEASURES OF MATERNAL STRESS (MATERNAL WAR TRAUMA, CHRONIC STRESS, AND EXPERIENCE OF SEXUAL VIOLENCE) AND ONE HEALTH OUTCOME (NEWBORN BIRTH WEIGHT). WE OBSERVED THAT MATERNAL EXPERIENCES OF WAR TRAUMA, CHRONIC STRESS, AND SEXUAL ASSAULT WERE EACH ASSOCIATED WITH DECREASED NEWBORN BIRTH WEIGHT (P < 1.95 X 10(-7) IN ALL CASES). TESTING INDIVIDUAL CPG SITES USING EWAS, WE OBSERVED NO ASSOCIATIONS BETWEEN DNAM AND ANY MEASURE OF MATERNAL STRESS OR NEWBORN BIRTH WEIGHT IN EITHER MATERNAL OR CORD BLOOD, AFTER BONFERRONI MULTIPLE TESTING CORRECTION. HOWEVER, THE TOP-RANKED CPG SITE IN MATERNAL BLOOD THAT ASSOCIATED WITH MATERNAL CHRONIC STRESS AND SEXUAL VIOLENCE BEFORE MULTIPLE TESTING CORRECTION IS LOCATED NEAR THE SPON1 GENE. TESTING AT A REGIONAL LEVEL, WE FOUND INCREASED METHYLATION OF A VMR IN MATERNAL BLOOD NEAR SPON1 THAT WAS ASSOCIATED WITH CHRONIC STRESS AND SEXUAL VIOLENCE AFTER BONFERRONI MULTIPLE TESTING CORRECTION (P = 1.95 X 10(-7) AND 8.3 X 10(-6), RESPECTIVELY). AT THE EPIGENOMIC LEVEL, CORD BLOOD GMM WAS ASSOCIATED WITH SIGNIFICANTLY HIGHER LEVELS OF WAR TRAUMA (P = 0.025) AND WAS SUGGESTIVELY ASSOCIATED WITH SEXUAL VIOLENCE (P = 0.053). THE OTHER TWO EPIGENOME-WIDE MEASURES WERE NOT ASSOCIATED WITH MATERNAL STRESS OR NEWBORN BIRTH WEIGHT IN EITHER TISSUE TYPE. DESPITE OUR SMALL SAMPLE SIZE, WE IDENTIFIED ASSOCIATIONS EVEN AFTER CONSERVATIVE MULTIPLE TESTING CORRECTION. SPECIFICALLY, WE FOUND ASSOCIATIONS BETWEEN DNAM AND THE THREE MEASURES OF MATERNAL STRESS ACROSS BOTH TISSUES; SPECIFICALLY, A VMR IN MATERNAL BLOOD AND GMM IN CORD BLOOD WERE BOTH ASSOCIATED WITH DIFFERENT MEASURES OF MATERNAL STRESS. THE ASSOCIATION OF CORD BLOOD GMM, BUT NOT MATERNAL BLOOD GMM, WITH MATERNAL STRESS MAY SUGGEST DIFFERENT RESPONSES TO STRESS IN MOTHER AND NEWBORN. IT IS NOTEWORTHY THAT WE FOUND ASSOCIATIONS ONLY WHEN CPG SITES WERE ANALYZED IN AGGREGATE, EITHER AS VMRS OR AS A BROAD SUMMARY MEASURE OF GMM.	2019
