1  3145 150 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
2  4847  25 OPIOID DEPENDENCE AND PREGNANCY: MINIMIZING STRESS ON THE FETAL BRAIN. INCREASE IN THE NUMBER OF OPIOID-DEPENDENT PREGNANT WOMEN DELIVERING BABIES AT RISK FOR NEONATAL ABSTINENCE SYNDROME PROMPTED A US GOVERNMENT ACCOUNTABILITY OFFICE REPORT DOCUMENTING DEFICITS IN RESEARCH AND PROVIDER KNOWLEDGE ABOUT CARE OF THE MATERNAL/FETAL UNIT AND THE NEONATE. THERE ARE 3 GENERAL SOURCES OF DEPENDENCE: UNTREATED OPIOID USE DISORDER, PAIN MANAGEMENT, AND MEDICATION-ASSISTED TREATMENT WITH METHADONE OR BUPRENORPHINE. A SURVEY OF METHADONE PATIENTS' EXPERIENCES WHEN TELLING A PHYSICIAN OF THEIR PREGNANCY AND OPIOID DEPENDENCE DEMONSTRATED PHYSICIAN CONFUSION ABOUT PROPER CARE, FREQUENT NEGATIVE INTERACTIONS WITH THE MOTHER, AND FAILURES TO PROVIDE APPROPRIATE REFERRAL. PATIENTS IN PAIN MANAGEMENT WERE DISCHARGED WITHOUT REFERRAL WHEN THE PHYSICIAN WAS TOLD OF THE PREGNANCY. METHADONE AND BUPRENORPHINE WERE FREQUENTLY SEEN NEGATIVELY BECAUSE THEY "CAUSED" NEONATAL ABSTINENCE SYNDROME. MOST MOTHERS SURVEYED HAD TO FIND OPIOID TREATMENT ON THEIR OWN. HOW DEPENDENCE IS MANAGED MEDICALLY IS A CRITICAL DETERMINANT OF THE LEVEL OF STRESS ON BOTH MOTHER AND FETUS, AND THEREFORE ANOTHER DETERMINANT OF NEONATAL HEALTH. THE EFFECTS OF BOTH OPIOID WITHDRAWAL STRESS AND MATERNAL EMOTIONAL STRESS ON NEONATAL AND DEVELOPMENTAL OUTCOMES ARE REVIEWED. CURRENTLY, THERE HAVE BEEN EFFORTS TO CRIMINALIZE MATERNAL OPIOID DEPENDENCE AND TO ENCOURAGE OR COERCE PREGNANT WOMEN TO UNDERGO WITHDRAWAL. THIS PRACTICE POSES BOTH ACUTE RISKS OF FETAL HYPOXIA AND LONG-TERM RISKS OF ADVERSE EPIGENETIC PROGRAMMING RELATED TO CATECHOLAMINE AND CORTICOSTEROID SURGES DURING WITHDRAWAL. CONTEMPORARY STUDIES OF THE EFFECTS OF WITHDRAWAL STRESS ON THE DEVELOPING FETAL BRAIN ARE URGENTLY NEEDED TO ELUCIDATE AND QUANTIFY THE RISKS OF SUCH PRACTICES. AT BIRTH, INCONSISTENCIES IN THE HOSPITAL MANAGEMENT OF NEONATES AT RISK FOR NEONATAL ABSTINENCE SYNDROME HAVE BEEN OBSERVED. NEGLECT OF THE CRITICAL ROLE OF MATERNAL COMFORTING IN NEONATAL ABSTINENCE SYNDROME MANAGEMENT IS AN IATROGENIC AND PREVENTABLE CAUSE OF POOR OUTCOMES AND LONG HOSPITALIZATIONS. ROOMING-IN ALLOWS FOR CONTINUOUS CARE OF THE BABY AND MATERNAL/NEONATAL ATTACHMENT, OFTEN UNWITTINGLY DISRUPTED BY THE NEONATAL INTENSIVE CARE UNIT ENVIRONMENT. RECOMMENDATIONS ARE MADE FOR FURTHER RESEARCH INTO PHYSICIAN/PATIENT INTERACTIONS AND INTO OPTIMAL DOSING OF METHADONE AND BUPRENORPHINE TO MINIMIZE MATERNAL/FETAL WITHDRAWAL.	2017	

3  1235  22 CUMULATIVE PROCEDURAL PAIN AND BRAIN DEVELOPMENT IN VERY PRETERM INFANTS: A SYSTEMATIC REVIEW OF CLINICAL AND PRECLINICAL STUDIES. VERY PRETERM INFANTS MAY MANIFEST NEURODEVELOPMENTAL IMPAIRMENTS, EVEN IN THE ABSENCE OF BRAIN LESIONS. PATHOGENESIS IS COMPLEX AND MULTIFACTORIAL. EVIDENCE SUGGESTS A ROLE OF EARLY ADVERSITIES ON NEURODEVELOPMENTAL OUTCOMES, VIA EPIGENETIC REGULATION AND CHANGES IN BRAIN ARCHITECTURE. IN THIS CONTEXT, WE FOCUSED ON CUMULATIVE PAIN EXPOSURE WHICH PRETERM NEONATES EXPERIENCE IN NEONATAL INTENSIVE CARE UNIT (NICU). WE SYSTEMATICALLY SEARCHED FOR: I) EVIDENCE LINKING PAIN WITH BRAIN DEVELOPMENT AND EXPLORING THE POTENTIAL PATHOGENETIC ROLE OF EPIGENETICS; II) PRECLINICAL RESEARCH SUPPORTING CLINICAL OBSERVATIONAL STUDIES. NINE CLINICAL NEUROIMAGING STUDIES, DURING NEONATAL OR SCHOOL AGE, MOSTLY FROM THE SAME RESEARCH GROUP, REVEALED VOLUME REDUCTION OF WHITE AND GRAY MATTER STRUCTURES IN ASSOCIATION WITH POSTNATAL PAIN EXPOSURE. THREE CONTROLLED ANIMAL STUDIES MIMICKING NICU SETTINGS FOUND INCREASED CELL DEATH OR APOPTOSIS; NEVERTHELESS, ELIGIBLE GROUPS WERE LIMITED IN SIZE. EPIGENETIC MODULATION (SLC6A4 PROMOTER METHYLATION) WAS IDENTIFIED IN ONLY TWO CLINICAL TRIALS. WE CALL FOR ADDITIONAL RESEARCH AND, ALTHOUGH KNOWLEDGE GAPS, WE ALSO POINT OUT THE URGENT NEED OF MINIMIZING PAINFUL PROCEDURES IN NICUS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
4  5192  33 PRENATAL ENVIRONMENTAL STRESSORS AND DNA METHYLATION LEVELS IN PLACENTA AND PERIPHERAL TISSUES OF MOTHERS AND NEONATES EVALUATED BY APPLYING ARTIFICIAL NEURAL NETWORKS. EXPOSURE TO ENVIRONMENTAL STRESSORS DURING PREGNANCY PLAYS AN IMPORTANT ROLE IN INFLUENCING SUBSEQUENT SUSCEPTIBILITY TO CERTAIN CHRONIC DISEASES THROUGH THE MODULATION OF EPIGENETIC MECHANISMS, INCLUDING DNA METHYLATION. OUR AIM WAS TO EXPLORE THE CONNECTIONS BETWEEN ENVIRONMENTAL EXPOSURES DURING GESTATION WITH DNA METHYLATION OF PLACENTAL CELLS, MATERNAL AND NEONATAL BUCCAL CELLS BY APPLYING ARTIFICIAL NEURAL NETWORKS (ANNS). A TOTAL OF 28 MOTHER-INFANT PAIRS WERE ENROLLED. DATA ON GESTATIONAL EXPOSURE TO ADVERSE ENVIRONMENTAL FACTORS AND ON MOTHER HEALTH STATUS WERE COLLECTED THROUGH THE ADMINISTRATION OF A QUESTIONNAIRE. DNA METHYLATION ANALYSES AT BOTH GENE-SPECIFIC AND GLOBAL LEVEL WERE ANALYZED IN PLACENTAS, MATERNAL AND NEONATAL BUCCAL CELLS. IN THE PLACENTA, THE CONCENTRATIONS OF VARIOUS METALS AND DIOXINS WERE ALSO ANALYZED. ANALYSIS OF ANNS REVEALED THAT SUBOPTIMAL BIRTH WEIGHT IS ASSOCIATED WITH PLACENTAL H19 METHYLATION, MATERNAL STRESS DURING PREGNANCY WITH METHYLATION LEVELS OF NR3C1 AND BDNF IN PLACENTAS AND MOTHER'S BUCCAL DNA, RESPECTIVELY, AND EXPOSURE TO AIR POLLUTANTS WITH MATERNAL MGMT METHYLATION. ASSOCIATIONS WERE ALSO OBSERVED BETWEEN PLACENTAL CONCENTRATIONS OF LEAD, CHROMIUM, CADMIUM AND MERCURY WITH METHYLATION LEVELS OF OXTR IN PLACENTAS, HSD11B2 IN MATERNAL BUCCAL CELLS AND PLACENTAS, MECP2 IN NEONATAL BUCCAL CELLS, AND MTHFR IN MATERNAL BUCCAL CELLS. FURTHERMORE, DIOXIN CONCENTRATIONS WERE ASSOCIATED WITH PLACENTAL RELN, NEONATAL HSD11B2 AND MATERNAL H19 GENE METHYLATION LEVELS. CURRENT RESULTS SUGGEST THAT EXPOSURE OF PREGNANT WOMEN TO ENVIRONMENTAL STRESSORS DURING PREGNANCY COULD INDUCE ABERRANT METHYLATION LEVELS IN GENES LINKED TO SEVERAL PATHWAYS IMPORTANT FOR EMBRYOGENESIS IN BOTH THE PLACENTA, POTENTIALLY AFFECTING FOETAL DEVELOPMENT, AND IN THE PERIPHERAL TISSUES OF MOTHERS AND INFANTS, POTENTIALLY PROVIDING PERIPHERAL BIOMARKERS OF ENVIRONMENTAL EXPOSURE.	2023	
                                                                                                                                                                                                                                                                                                                                                                                
5  3664  23 INFANT NEUROBEHAVIORAL DEVELOPMENT. THE TREND TOWARD SINGLE-ROOM NEONATAL INTENSIVE CARE UNITS (NICUS) IS INCREASING; HOWEVER SCIENTIFIC EVIDENCE IS, AT THIS POINT, MOSTLY ANECDOTAL. THIS IS A CRITICAL TIME TO ASSESS THE IMPACT OF THE SINGLE-ROOM NICU ON IMPROVING MEDICAL AND NEUROBEHAVIORAL OUTCOMES OF THE PRETERM INFANT. WE HAVE DEVELOPED A THEORETICAL MODEL THAT MAY BE USEFUL IN STUDYING HOW THE CHANGE FROM AN OPEN-BAY NICU TO A SINGLE-ROOM NICU COULD AFFECT INFANT MEDICAL AND NEUROBEHAVIORAL OUTCOME. THE MODEL IDENTIFIES MEDIATING FACTORS THAT ARE LIKELY TO ACCOMPANY THE CHANGE TO A SINGLE-ROOM NICU. THESE MEDIATING FACTORS INCLUDE FAMILY CENTERED CARE, DEVELOPMENTAL CARE, PARENTING AND FAMILY FACTORS, STAFF BEHAVIOR AND ATTITUDES, AND MEDICAL PRACTICES. MEDICAL OUTCOMES THAT PLAN TO BE MEASURED ARE SEPSIS, LENGTH OF STAY, GESTATIONAL AGE AT DISCHARGE, WEIGHT GAIN, ILLNESS SEVERITY, GESTATIONAL AGE AT ENTERAL FEEDING, AND NECROTIZING ENTEROCOLITIS (NEC). NEUROBEHAVIORAL OUTCOMES INCLUDE THE NICU NETWORK NEUROBEHAVIORAL SCALE (NNNS) SCORES, SLEEP STATE ORGANIZATION AND SLEEP PHYSIOLOGY, INFANT MOTHER FEEDING INTERACTION SCORES, AND PAIN SCORES. PRELIMINARY FINDINGS ON THE SAMPLE OF 150 PATIENTS IN THE OPEN-BAY NICU SHOWED A "BASELINE" OF EFFECTS OF FAMILY CENTERED CARE, DEVELOPMENTAL CARE, PARENT SATISFACTION, MATERNAL DEPRESSION, AND PARENTING STRESS ON THE NEUROBEHAVIORAL OUTCOMES OF THE NEWBORN. THE SINGLE-ROOM NICU HAS THE POTENTIAL TO IMPROVE THE NEUROBEHAVIORAL STATUS OF THE INFANT AT DISCHARGE. NEUROBEHAVIORAL ASSESSMENT CAN ASSIST WITH EARLY DETECTION AND THEREFORE PREVENTATIVE INTERVENTION TO MAXIMIZE DEVELOPMENTAL OUTCOME. WE ALSO PRESENT AN EPIGENETIC MODEL OF THE POTENTIAL EFFECTS OF MATERNAL CARE ON IMPROVING INFANT NEUROBEHAVIORAL STATUS.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
6  4275  22 MICROGLIA ACTIVATION IN THE MIDBRAIN OF THE HUMAN NEONATE: THE EFFECT OF PERINATAL HYPOXIC-ISCHEMIC INJURY. PERINATAL HYPOXIA-ISCHEMIA (PHI) IS A MAJOR RISK FACTOR FOR THE DEVELOPMENT OF NEUROPSYCHIATRIC DEFICITS LATER IN LIFE. WE PREVIOUSLY REPORTED THAT AFTER PROLONGED PHI, THE DOPAMINERGIC NEURONS OF THE HUMAN NEONATE SHOWED A DRAMATIC REDUCTION OF TYROSINE HYDROXYLASE (TH) IN THE SUBSTANTIA NIGRA, WITHOUT IMPORTANT SIGNS OF NEURONAL DEGENERATION DESPITE THE SIGNIFICANT REDUCTION IN THEIR CELL SIZE. SINCE MICROGLIA ACTIVATION COULD PRECEDE NEURONAL DEATH, WE NOW INVESTIGATED 2 MICROGLIA ACTIVATION MARKERS, IONIZED CALCIUM-BINDING ADAPTER MOLECULE 1 (IBA1), AND THE PHAGOCYTOSIS MARKER CD68. THE HIGHEST IBA1 IMMUNOREACTIVITY WAS FOUND IN NEONATES WITH NEUROPATHOLOGICAL LESIONS OF SEVERE/ABRUPT PHI, WHILE THE LOWEST IN SUBJECTS WITH MODERATE/PROLONGED OR OLDER PHI. SUBJECTS WITH VERY SEVERE/PROLONGED OR CHRONIC PHI SHOWED AN INCREASED IBA1 EXPRESSION AND VERY ACTIVATED MICROGLIAL MORPHOLOGY. HEAVY ATTACHMENT OF MICROGLIA ON TH NEURONS AND REMARKABLE EXPRESSION OF CD68 WERE ALSO OBSERVED INDICATING PHAGOCYTOSIS IN THIS GROUP. FEMALES APPEAR TO EXPRESS MORE IBA1 THAN MALES, SUGGESTING A GENDER DIFFERENCE IN MICROGLIA MATURATION AND IMMUNE REACTIVITY AFTER PHI INSULT. PHI-INDUCED MICROGLIAL "PRIMING" DURING THE SENSITIVE FOR BRAIN DEVELOPMENT PERINATAL/NEONATAL PERIOD, IN COMBINATION WITH GENETIC OR OTHER EPIGENETIC FACTORS, COULD PREDISPOSE THE SURVIVORS TO NEUROPSYCHIATRIC DISORDERS LATER IN LIFE, POSSIBLY THROUGH A SEXUALLY DIMORPHIC WAY.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
7  4612  23 NEONATAL PAIN AND COMT VAL158MET GENOTYPE IN RELATION TO SEROTONIN TRANSPORTER (SLC6A4) PROMOTER METHYLATION IN VERY PRETERM CHILDREN AT SCHOOL AGE. CHILDREN BORN VERY PRETERM ARE EXPOSED TO REPEATED NEONATAL PROCEDURES THAT INDUCE PAIN AND STRESS DURING HOSPITALIZATION IN THE NEONATAL INTENSIVE CARE UNIT (NICU). THE COMT VAL158MET GENOTYPE IS INVOLVED WITH PAIN SENSITIVITY, AND EARLY LIFE STRESS IS IMPLICATED IN ALTERED EXPRESSION OF METHYLATION OF THE SEROTONIN TRANSPORTER. WE EXAMINED: (1) WHETHER METHYLATION OF THE SEROTONIN TRANSPORTER GENE (SLC6A4) PROMOTER DIFFERS BETWEEN VERY PRETERM CHILDREN AND FULL-TERM CONTROLS AT SCHOOL AGE, (2) RELATIONSHIPS WITH CHILD BEHAVIOR PROBLEMS, AND (3) WHETHER THE EXTENT OF NEONATAL PAIN EXPOSURE INTERACTS WITH THE COMT VAL158MET GENOTYPE TO PREDICT SLC6A4 METHYLATION AT 7 YEARS IN THE VERY PRETERM CHILDREN. WE EXAMINED THE ASSOCIATIONS BETWEEN THE COMT GENOTYPES, NEONATAL PAIN EXPOSURE (ADJUSTED FOR NEONATAL CLINICAL CONFOUNDERS), SLC6A4 METHYLATION AND BEHAVIOR PROBLEMS. VERY PRETERM CHILDREN HAD SIGNIFICANTLY HIGHER METHYLATION AT 7/10 CPG SITES IN THE SLC6A4 PROMOTER COMPARED TO FULL-TERM CONTROLS AT 7 YEARS. NEONATAL PAIN (ADJUSTED FOR CLINICAL CONFOUNDERS) WAS SIGNIFICANTLY ASSOCIATED WITH TOTAL CHILD BEHAVIOR PROBLEMS ON THE CHILD BEHAVIOR CHECKLIST (CBCL) QUESTIONNAIRE (ADJUSTED FOR CONCURRENT STRESSORS AND 5HTTLPR GENOTYPE) (P = 0.035). CBCL TOTAL PROBLEMS WAS SIGNIFICANTLY ASSOCIATED WITH GREATER SLC6A4 METHYLATION IN VERY PRETERM CHILDREN (P = 0.01). NEONATAL PAIN (ADJUSTED FOR CLINICAL CONFOUNDERS) AND COMT MET/MET GENOTYPE WERE ASSOCIATED WITH SLC6A4 PROMOTER METHYLATION IN VERY PRETERM CHILDREN AT 7 YEARS (P = 0.001). THESE FINDINGS PROVIDE EVIDENCE THAT BOTH GENETIC PREDISPOSITION AND EARLY ENVIRONMENT NEED TO BE CONSIDERED IN UNDERSTANDING SUSCEPTIBILITY FOR DEVELOPING BEHAVIORAL PROBLEMS IN THIS VULNERABLE POPULATION.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
8  5214  17 PRETERM BEHAVIORAL EPIGENETICS: A SYSTEMATIC REVIEW. BEHAVIORAL EPIGENETICS IS REVEALING NEW PATHWAYS THAT LEAD INDIVIDUALS FROM EARLY ADVERSITY EXPOSURES TO LATER-IN-LIFE DETRIMENTAL OUTCOMES. PRETERM BIRTH CONSTITUTES ONE OF THE MAJOR ADVERSE EVENTS IN HUMAN DEVELOPMENT. PRETERM INFANTS ARE HOSPITALIZED IN THE NEONATAL INTENSIVE CARE UNIT (NICU) WHERE THEY ARE EXPOSED TO LIFE-SAVING YET PAIN-INDUCING PROCEDURES AND TO PROTECTIVE CARE. THE APPLICATION OF BEHAVIORAL EPIGENETICS TO THE FIELD OF PRETERM STUDIES (I.E., PRETERM BEHAVIORAL EPIGENETICS, PBE) IS RAPIDLY GROWING AND HOLDS PROMISES TO PROVIDE VALID INSIGHTS FOR RESEARCH AND CLINICAL ACTIVITY. HERE, THE EVIDENCE OF THE EPIGENETIC CORRELATES OF PRENATAL ADVERSITIES, NICU-RELATED ENVIRONMENT AND DEVELOPMENT OF PRETERM INFANTS IS SYSTEMATICALLY REVIEWED. THE FINDINGS SUGGEST THAT A NUMBER OF PRENATAL ADVERSE (E.G., MATERNAL DEPRESSION AND STRESS) AND POST-NATAL (E.G., NICU-RELATED PAIN-RELATED STRESS) EVENTS AFFECT THE DEVELOPMENTAL TRAJECTORIES OF PRETERM INFANTS AND CHILDREN VIA EPIGENETIC ALTERATIONS OF IMPRINTED AND STRESS-RELATED GENES. NONETHELESS, THE POTENTIAL EPIGENETIC VESTIGES OF EARLY CARE AND PROTECTIVE INTERVENTIONS IN NICU HAVE NOT BEEN INVESTIGATED YET AND THIS REPRESENTS A FASCINATING CHALLENGE FOR FUTURE PBE RESEARCH.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
9  4917  22 PAIN-RELATED STRESS DURING THE NEONATAL INTENSIVE CARE UNIT STAY AND SLC6A4 METHYLATION IN VERY PRETERM INFANTS. VERY PRETERM (VPT) INFANTS NEED LONG-LASTING HOSPITALIZATION IN THE NEONATAL INTENSIVE CARE UNIT (NICU) DURING WHICH THEY ARE DAILY EXPOSED TO PAIN-RELATED STRESS. ALTERATIONS OF DNA METHYLATION AT THE PROMOTER REGION OF THE SLC6A4 HAVE BEEN ASSOCIATED WITH EARLY ADVERSE EXPERIENCES IN INFANTS. THE MAIN AIM OF THE PRESENT WORK WAS TO INVESTIGATE THE ASSOCIATION BETWEEN LEVEL OF EXPOSURE TO PAIN-RELATED STRESS DURING HOSPITALIZATION AND CHANGES IN SLC6A4 DNA METHYLATION AT NICU DISCHARGE IN VPT INFANTS. IN ORDER TO EXCLUDE THE POTENTIAL EFFECT OF BIRTH STATUS (I.E., PRETERM VS. FULL-TERM BIRTH) ON SLC6A4 METHYLATION, WE PRELIMINARILY ASSESSED SLC6A4 EPIGENETIC DIFFERENCES BETWEEN VPT AND FULL-TERM (FT) INFANTS AT BIRTH. FIFTY-SIX VPT AND THIRTY-TWO FT INFANTS PARTICIPATED IN THE STUDY. THE LEVEL OF EXPOSURE TO PAIN-RELATED STRESS WAS QUANTIFIED ON THE BASIS OF THE AMOUNT OF SKIN-BREAKING PROCEDURES TO WHICH THEY WERE EXPOSED. VPT INFANTS WERE DIVIDED IN TWO SUB-GROUPS: LOW-PAIN EXPOSURE (LPE, N = 25) AND HIGH-PAIN EXPOSURE (HPE, N = 31). DNA METHYLATION WAS EVALUATED AT BIRTH FOR BOTH VPT AND FT INFANTS, ASSESSING 20 CPG SITES WITHIN THE SLC6A4 PROMOTER REGION. THE SAME CPG SITES WERE RE-EVALUATED FOR VARIATIONS IN DNA METHYLATION AT NICU DISCHARGE IN LPE AND HPE VPT INFANTS. NO DIFFERENCES IN SLC6A4 CPG SITES' METHYLATION EMERGED BETWEEN FT AND VPT INFANTS AT BIRTH. METHYLATION AT CPG SITES 5 AND 6 SIGNIFICANTLY INCREASED FROM BIRTH TO NICU DISCHARGE ONLY FOR HPE VPT INFANTS. FINDINGS SHOW THAT PRETERM BIRTH PER SE IS NOT ASSOCIATED WITH EPIGENETIC ALTERATIONS OF THE SLC6A4, WHEREAS HIGHER LEVELS OF PAIN-RELATED STRESS EXPOSURE DURING NICU STAY MIGHT ALTER THE TRANSCRIPTIONAL FUNCTIONALITY OF THE SEROTONIN TRANSPORTER GENE.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
10  4910  25 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	
                                                                                                                                                                                                                                                                                                                                                                                                                 
11  5961  23 TELOMERE LENGTH IN PRETERM INFANTS: A PROMISING BIOMARKER OF EARLY ADVERSITY AND CARE IN THE NEONATAL INTENSIVE CARE UNIT? PRETERM INFANTS PRESENT AN IMMATURE NEUROBEHAVIORAL PROFILE AT BIRTH, EVEN IN ABSENCE OF SEVERE BRAIN INJURIES AND PERINATAL COMPLICATIONS. AS SUCH, THEY REQUIRE A LONG-LASTING HOSPITALIZATION IN THE NEONATAL INTENSIVE CARE UNIT (NICU), WHICH IS THOUGHT TO GRANT AT-RISK NEWBORNS' SURVIVAL, BUT STILL ENTAILS A NUMBER OF PHYSICAL, PAINFUL, AND SOCIO-EMOTIONAL STRESSORS. HENCE, PRETERM BIRTH AND NICU STAY REPRESENT AN EARLY ADVERSE EXPERIENCE, WHICH HAS BEEN LINKED TO DETRIMENTAL CONSEQUENCES FOR NEUROLOGICAL, NEURO-ENDOCRINAL, BEHAVIORAL, AND SOCIO-EMOTIONAL DEVELOPMENT, AS WELL AS TO DISEASE LATER IN LIFE. RECENT ADVANCES IN THE BEHAVIORAL EPIGENETIC FIELD ARE HELPING US TO UNVEIL THE POTENTIAL MECHANISMS THROUGH WHICH EARLY NICU-RELATED STRESS MAY LEAD TO NEGATIVE DEVELOPMENTAL OUTCOMES. FROM THIS PERSPECTIVE, TELOMERE REGULATION MIGHT BE A KEY PROGRAMMING MECHANISM. TELOMERES ARE THE TERMINAL PORTION OF CHROMOSOMES AND ARE KNOWN TO GET SHORTER WITH AGE. MOREOVER, TELOMERE LENGTH (TL) IS AFFECTED BY THE EXPOSURE TO STRESS DURING EARLY DEVELOPMENT. AS SUCH, TL MIGHT BE AN INNOVATIVE BIOMARKER OF EARLY ADVERSE EXPOSURES IN YOUNG INFANTS AND CHILDREN. UNFORTUNATELY, THERE IS PAUCITY OF STUDIES INVESTIGATING TL IN POPULATIONS OF PRETERM INFANTS AND ITS ASSOCIATION WITH KNOWN NICU-RELATED STRESSORS REMAINS UNEXPLORED. IN THE PRESENT PAPER, THE POTENTIAL RELEVANCE OF TL FOR RESEARCH AND CLINICAL WORK WITH PRETERM INFANTS WILL BE UNDERLINED IN THE LIGHT OF RECENT CONTRIBUTIONS LINKING PROGRESSIVE TELOMERE SHORTENING AND EARLY EXPOSURE TO ADVERSE EXPERIENCES AND STRESSFUL ENVIRONMENTS IN HUMANS. FINALLY, INSIGHTS WILL BE PROVIDED TO GUIDE CLINICALLY RELEVANT TRANSLATIONAL RESEARCH ON TL IN THE FIELD OF VPT BIRTH AND NICU STAY.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
12  2605  28 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
13  1392  25 DIAGNOSTIC APPROACH TO PULMONARY HYPERTENSION IN PREMATURE NEONATES. BRONCHOPULMONARY DYSPLASIA (BPD) IS A FORM OF CHRONIC LUNG DISEASE IN PREMATURE INFANTS FOLLOWING RESPIRATORY DISTRESS AT BIRTH. WITH INCREASING SURVIVAL OF EXTREMELY LOW BIRTH WEIGHT INFANTS, ALVEOLAR SIMPLIFICATION IS THE DEFINING LUNG CHARACTERISTIC OF INFANTS WITH BPD, AND ALONG WITH PULMONARY HYPERTENSION, INCREASINGLY CONTRIBUTES TO BOTH RESPIRATORY MORBIDITY AND MORTALITY IN THESE INFANTS. GROWTH RESTRICTED INFANTS, INFANTS BORN TO MOTHERS WITH OLIGOHYDRAMNIOS OR FOLLOWING PROLONGED PRETERM RUPTURE OF MEMBRANES ARE AT PARTICULAR RISK FOR EARLY ONSET PULMONARY HYPERTENSION. ALTERED VASCULAR AND ALVEOLAR GROWTH PARTICULARLY IN CANALICULAR AND EARLY SACCULAR STAGES OF LUNG DEVELOPMENT FOLLOWING MECHANICAL VENTILATION AND OXYGEN THERAPY, RESULTS IN DEVELOPMENTAL LUNG ARREST LEADING TO BPD WITH PULMONARY HYPERTENSION (PH). EARLY RECOGNITION OF PH IN INFANTS WITH RISK FACTORS IS IMPORTANT FOR OPTIMAL MANAGEMENT OF THESE INFANTS. SCREENING TOOLS FOR EARLY DIAGNOSIS OF PH ARE EVOLVING; HOWEVER, ECHOCARDIOGRAPHY IS THE MAINSTAY FOR NON-INVASIVE DIAGNOSIS OF PH IN INFANTS. CARDIAC COMPUTED TOMOGRAPHY (CT) AND MAGNETIC RESONANCE ARE BEING USED AS IMAGING MODALITIES, HOWEVER THEIR ROLE IN IMPROVING OUTCOMES IN THESE PATIENTS IS UNCERTAIN. FOLLOW-UP OF INFANTS AT RISK FOR PH WILL HELP NOT ONLY IN EARLY DIAGNOSIS, BUT ALSO IN APPROPRIATE MANAGEMENT OF THESE INFANTS. AGGRESSIVE MANAGEMENT OF LUNG DISEASE, AVOIDANCE OF HYPOXEMIC EPISODES, AND OPTIMAL NUTRITION DETERMINE THE PROGRESSION OF PH, AS EPIGENETIC FACTORS MAY HAVE SIGNIFICANT EFFECTS, PARTICULARLY IN GROWTH-RESTRICTED INFANTS. INFANTS WITH DIAGNOSIS OF PH ARE MANAGED WITH PULMONARY VASODILATORS AND THOSE RESISTANT TO THERAPY NEED TO BE WORKED UP FOR THE PRESENCE OF CARDIO-VASCULAR ANOMALIES. THE MANAGEMENT OF INFANTS AND TODDLERS WITH PH, ESPECIALLY FOLLOWING PREMATURE BIRTH IS AN EMERGING FIELD. NONETHELESS, COMBINATION THERAPIES IN A MULTI-DISCIPLINARY SETTING IMPROVES OUTCOMES FOR THESE INFANTS.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                              
14  2484  29 EPIGENETIC, TRANSCRIPTIONAL AND PHENOTYPIC RESPONSES IN TWO GENERATIONS OF DAPHNIA MAGNA EXPOSED TO THE DNA METHYLATION INHIBITOR 5-AZACYTIDINE. THE WATER FLEA DAPHNIA MAGNA IS A KEYSTONE SPECIES IN FRESHWATER ECOSYSTEMS AND HAS BEEN WIDELY USED AS A MODEL ORGANISM IN ENVIRONMENTAL ECOTOXICOLOGY. THIS AQUATIC CRUSTACEAN IS SENSITIVE TO ENVIRONMENTAL STRESSORS AND DISPLAYS CONSIDERABLE PLASTICITY IN ADAPTING TO CHANGING ENVIRONMENTAL CONDITIONS. PART OF THIS PLASTICITY MAY BE DUE TO EPIGENETIC REGULATION OF GENE EXPRESSION, INCLUDING CHANGES TO DNA METHYLATION AND HISTONE MODIFICATIONS. BECAUSE OF THE GENERALLY HYPOMETHYLATED GENOME OF THIS SPECIES, WE HYPOTHESIZED THAT THE HISTONE CODE MAY HAVE AN ESSENTIAL ROLE IN THE EPIGENETIC CONTROL AND THAT HISTONE MODIFICATIONS MIGHT BE AN EARLY MARKER FOR STRESS. THIS STUDY AIMS TO CHARACTERIZE THE EPIGENETIC, TRANSCRIPTIONAL AND PHENOTYPIC RESPONSES AND THEIR CAUSAL LINKAGES IN DIRECTLY EXPOSED ADULT (F0) DAPHNIA AND PERITONEAL EXPOSED NEONATES (F1) AFTER A CHRONIC (7-DAY) EXPOSURE TO A SUBLETHAL CONCENTRATION (10 MG/L) OF 5-AZACYTIDINE, A WELL-STUDIED VERTEBRATE DNA METHYLATION INHIBITOR. EXPOSURE OF THE F0 GENERATION SIGNIFICANTLY REDUCED THE CUMULATIVE FECUNDITY, ACCOMPANIED WITH DIFFERENTIAL EXPRESSION OF GENES IN THE ONE-CARBON-CYCLE METABOLIC PATHWAY. IN THE EPIGENOME OF THE F0 GENERATION, A DECREASE IN GLOBAL DNA METHYLATION, BUT NO SIGNIFICANT CHANGES ON H3K4ME3 OR H3K27ME3, WERE OBSERVED. IN THE F1 OFFSPRING GENERATION, CHANGES IN GENE EXPRESSION, A SIGNIFICANT REDUCTION IN GLOBAL DNA METHYLATION AND CHANGES IN HISTONE MODIFICATIONS WERE IDENTIFIED. THE RESULTS INDICATE THAT EXPOSURE DURING ADULTHOOD MAY RESULT IN MORE PRONOUNCED EFFECTS ON EARLY DEVELOPMENT IN THE OFFSPRING GENERATION, THOUGH INTERPRETATION OF THE DATA SHOULD BE CAREFULLY DONE SINCE BOTH THE EXPOSURE REGIME AND DEVELOPMENTAL PERIOD IS DIFFERENT IN THE TWO GENERATIONS EXAMINED. THE OBTAINED RESULTS IMPROVE OUR UNDERSTANDING OF CRUSTACEAN EPIGENETICS AND THE TOOLS DEVELOPED MAY PROMOTE USE OF EPIGENETIC MARKERS IN HAZARD ASSESSMENT OF ENVIRONMENTAL STRESSORS.	2019	
                                                                                                                                                                                                                                                                                                                                                                 
15   520  33 ASSOCIATIONS BETWEEN MATERNAL PRENATAL STRESS, METHYLATION CHANGES IN IGF1 AND IGF2, AND BIRTH WEIGHT. MATERNAL STRESS HAS BEEN LINKED TO LOW BIRTH WEIGHT IN NEWBORNS. ONE POTENTIAL PATHWAY INVOLVES EPIGENETIC CHANGES AT CANDIDATE GENES THAT MAY MEDIATE THE EFFECTS OF PRENATAL MATERNAL STRESS ON BIRTH WEIGHT. THIS RELATIONSHIP HAS BEEN DOCUMENTED IN STRESS-RELATED GENES, SUCH AS NR3C1. THERE IS LESS LITERATURE EXPLORING THE EFFECT OF STRESS ON GROWTH-RELATED GENES. IGF1 AND IGF2 HAVE BEEN IMPLICATED IN FETAL GROWTH AND DEVELOPMENT, THOUGH VIA DIFFERENT MECHANISMS AS IGF2 IS UNDER IMPRINTING CONTROL. IN THIS STUDY, WE TESTED FOR ASSOCIATIONS BETWEEN PRENATAL STRESS, METHYLATION OF IGF1 AND IGF2, AND BIRTH WEIGHT. A TOTAL OF 24 MOTHER-NEWBORN DYADS IN THE DEMOCRATIC REPUBLIC OF CONGO WERE ENROLLED. ETHNOGRAPHIC INTERVIEWS WERE CONDUCTED WITH MOTHERS AT DELIVERY TO GATHER CULTURALLY RELEVANT WAR-RELATED AND CHRONIC STRESSORS. DNA METHYLATION DATA WERE GENERATED FROM MATERNAL VENOUS, CORD BLOOD AND PLACENTAL TISSUE SAMPLES. MULTIVARIATE REGRESSIONS WERE USED TO TEST FOR ASSOCIATIONS BETWEEN STRESS MEASURES, DNA METHYLATION AND BIRTH WEIGHT IN EACH OF THE THREE TISSUE TYPES. WE FOUND AN ASSOCIATION BETWEEN IGF2 METHYLATION IN MATERNAL BLOOD AND BIRTH WEIGHT. PREVIOUS LITERATURE ON THE RELATIONSHIP BETWEEN IGF2 METHYLATION AND BIRTH WEIGHT HAS FOCUSED ON METHYLATION AT KNOWN DIFFERENTIALLY METHYLATED REGIONS IN CORD BLOOD OR PLACENTAL SAMPLES. OUR FINDINGS INDICATE THERE MAY BE LINKS BETWEEN THE MATERNAL EPIGENOME AND LOW BIRTH WEIGHT THAT RELY ON MECHANISMS OUTSIDE KNOWN IMPRINTING PATHWAYS. IT THUS MAY BE IMPORTANT TO CONSIDER THE EFFECT OF MATERNAL EXPOSURES AND EPIGENETIC PROFILES ON BIRTH WEIGHT EVEN IN THE SETTING OF MATERNALLY IMPRINTED GENES SUCH AS IGF2.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
16  5178  25 PREGNANCY AS A FUNDAMENTAL DETERMINANT OF CHILD HEALTH: A REVIEW. PURPOSE OF REVIEW: MATERNAL CONDITIONS AND EXPOSURES DURING PREGNANCY INCLUDING OVER- AND UNDERNUTRITION ARE ASSOCIATED WITH POOR CHILDBIRTH OUTCOMES, GROWTH, DEVELOPMENT AND CHRONIC CHILDHOOD DISEASES. WE EXAMINED CONTEMPORARY PREGNANCY-RELATED DETERMINANTS OF CHILD HEALTH. RECENT FINDINGS: WHILE MATERNAL UNDERNUTRITION REMAINS A MAJOR CONTRIBUTOR TO LOW BIRTH WEIGHT, MATERNAL OBESITY AFFECTS FOETAL GROWTH, BIRTH WEIGHT, SURVIVAL AND IS ASSOCIATED WITH CHILDHOOD OBESITY, ASTHMA AND AUTISTIC SPECTRUM DISORDERS. EMERGING EVIDENCE SUGGESTS THAT EPIGENETIC CHANGES, THE PRENATAL MICROBIOME AND MATERNAL IMMUNE ACTIVATION (MIA), A NEUROINFLAMMATORY PROCESS INDUCED BY DIET AND OTHER EXPOSURES CAUSE FOETAL PROGRAMMING RESULTING IN THESE CHRONIC CHILDHOOD DISEASES. MATERNAL DIET IS POTENTIALLY A MODIFIABLE RISK FACTOR FOR CONTROLLING LOW BIRTH WEIGHT, OBESITY AND CHRONIC DISEASE IN CHILDHOOD. FURTHER STUDIES ARE WARRANTED TO REFINE GUIDANCE ON DIETARY RESTRICTION AND PHYSICAL ACTIVITY DURING PREGNANCY AND DETERMINE HOW MIA AND PRENATAL MICROBIOTA CAN BE APPLIED TO CONTROL CHILDHOOD DISEASES ARISING FROM PROGRAMMING.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
17  4065  34 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  4797  26 NUTRITIONAL INTERVENTIONS TO IMPROVE BRAIN OUTCOMES IN PRETERM INFANTS. THE LAST 20 YEARS HAVE SEEN DRAMATIC IMPROVEMENTS IN SURVIVAL FOR PRETERM INFANTS IN BOTH HIGH- AND LOW-INCOME SETTINGS. SURVIVAL RATES OF OVER 50% IN INFANTS BORN 16 WEEKS EARLY (24 WEEKS' GESTATION) ARE NOW COMMONPLACE IN WELL-RESOURCED NEONATAL INTENSIVE CARE UNITS. HOWEVER, ENSURING ADEQUATE NUTRIENT INTAKES ESPECIALLY IN THE FIRST FEW DAYS AND WEEKS IS CHALLENGING, AND MANY INFANTS SHOW POOR GROWTH AND NUTRITIONAL STATUS. GOOD NUTRITIONAL MANAGEMENT SHOULD BE SEEN AS THE CORNERSTONE OF GOOD NEONATAL CARE AND IS KEY TO IMPROVING A RANGE OF IMPORTANT OUTCOMES INCLUDING REDUCED RATES OF RETINOPATHY OF PREMATURITY, CHRONIC LUNG DISEASE, NECROTIZING ENTEROCOLITIS (NEC), AND SEPSIS. EQUALLY IMPORTANTLY, IS THAT GOOD NUTRITIONAL STATUS IS ESSENTIAL TO OPTIMIZE BRAIN GROWTH AND DIFFERENTIATION. THERE ARE MULTIPLE POTENTIAL MECHANISMS THAT LINK NUTRITION TO BRAIN OUTCOMES IN PRETERM INFANTS INCLUDING NEEDS FOR TISSUE ACCRETION, ENERGY SUPPLY, SIGNALING ROLES, FUNCTIONAL COMPONENTS IN HUMAN MILK, EPIGENETIC REGULATION, PREVENTION OF NEC AND DISEASE, AND IMPACTS ON THE GUT BRAIN AXES. THIS ARTICLE WILL REVIEW DATA IN SUPPORT OF DIFFERENT MECHANISTIC LINKS FOR THE IMPACT OF NUTRITION ON BRAIN OUTCOMES IN PRETERM INFANTS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
19  5200  30 PRENATAL MATERNAL STRESS PREDICTS METHYLATION OF GENES REGULATING THE HYPOTHALAMIC-PITUITARY-ADRENOCORTICAL SYSTEM IN MOTHERS AND NEWBORNS IN THE DEMOCRATIC REPUBLIC OF CONGO. EXPOSURE TO STRESS EARLY IN LIFE PERMANENTLY SHAPES ACTIVITY OF THE HYPOTHALAMIC-PITUITARY-ADRENOCORTICAL (HPA) AXIS AND THE BRAIN. PRENATALLY, GLUCOCORTICOIDS PASS THROUGH THE PLACENTA TO THE FETUS WITH POSTNATAL IMPACTS ON BRAIN DEVELOPMENT, BIRTH WEIGHT (BW), AND HPA AXIS FUNCTIONING. LITTLE IS KNOWN ABOUT THE BIOLOGICAL MECHANISMS BY WHICH PRENATAL STRESS AFFECTS POSTNATAL FUNCTIONING. THIS STUDY ADDRESSES THIS GAP BY EXAMINING THE EFFECT OF CHRONIC STRESS AND TRAUMATIC WAR-RELATED STRESS ON EPIGENETIC CHANGES IN FOUR KEY GENES REGULATING THE HPA AXIS IN NEONATAL CORD BLOOD, PLACENTA, AND MATERNAL BLOOD: CRH, CRHBP, NR3C1, AND FKBP5. PARTICIPANTS WERE 24 MOTHER-NEWBORN DYADS IN THE CONFLICT-RIDDEN REGION OF THE EASTERN DEMOCRATIC REPUBLIC OF CONGO. BW DATA WERE COLLECTED AT DELIVERY AND MATERNAL INTERVIEWS WERE CONDUCTED TO ASSESS CULTURALLY RELEVANT CHRONIC AND WAR-RELATED STRESSORS. CHRONIC STRESS AND WAR TRAUMA HAD WIDESPREAD EFFECTS ON HPA AXIS GENE METHYLATION, WITH SIGNIFICANT EFFECTS OBSERVED AT TRANSCRIPTION FACTOR BINDING (TFB) SITES IN ALL TARGET GENES TESTED. SOME CHANGES IN METHYLATION WERE UNIQUE TO CHRONIC OR WAR STRESS, WHEREAS OTHERS WERE OBSERVED ACROSS BOTH STRESSOR TYPES. MOREOVER, STRESS EXPOSURES IMPACTED MATERNAL AND FETAL TISSUES DIFFERENTLY, SUPPORTING THEORETICAL MODELS THAT STRESS IMPACTS VARY ACCORDING TO LIFE PHASE. METHYLATION IN SEVERAL NR3C1 AND CRH CPG SITES, ALL LOCATED AT TFB SITES, WAS ASSOCIATED WITH BW. THESE FINDINGS SUGGEST THAT PRENATAL STRESS EXPOSURE IMPACTS DEVELOPMENT VIA EPIGENETIC CHANGES IN HPA AXIS GENES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
20  5085  32 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
