1  5179 205 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
2  3342  27 HISTONE DEACETYLASE9 REPRESENTS THE EPIGENETIC PROMOTION OF M1 MACROPHAGE POLARIZATION AND INFLAMMATORY RESPONSE VIA TLR4 REGULATION. ATHEROSCLEROSIS IS A CHRONIC INFLAMMATORY RESPONSE MEDIATED BY VARIOUS FACTORS, WHERE EPIGENETIC REGULATION INVOLVING HISTONE DEACETYLATION IS ENVISAGED TO MODULATE THE EXPRESSION OF RELATED PROTEINS BY REGULATING THE BINDING OF TRANSCRIPTION FACTORS TO DNA, THEREBY INFLUENCING THE DEVELOPMENT OF ATHEROSCLEROSIS. THE MECHANISM OF ATHEROSCLEROSIS BY HISTONE DEACETYLATION IS PARTLY KNOWN; HENCE, THIS PROJECT AIMED AT INVESTIGATING THE ROLE OF HISTONE DEACETYLASE 9 (HDAC9) IN ATHEROSCLEROSIS. FOR THIS PURPOSE, SERUM WAS SEPARATED FROM BLOOD SAMPLES FOLLOWING CLOTTING AND CENTRIFUGATION FROM ATHEROSCLEROTIC AND HEALTHY PATIENTS (N = 40 EACH), AND THEN, VARIOUS TESTS WERE PERFORMED. THE RESULTS INDICATED THAT TOLL-LIKE RECEPTOR 4 (TLR4) WAS NOT ONLY POSITIVELY CORRELATED TO THE HDAC9 GENE, BUT WAS ALSO UPREGULATED IN ATHEROSCLEROSIS, WHERE IT WAS ALSO SIGNIFICANTLY UPREGULATED IN THE ATHEROSCLEROSIS CELL MODEL OF OXIDIZED LOW-DENSITY LIPOPROTEIN-INDUCED MACROPHAGES. CONVERSELY, THE TLR4 WAS SIGNIFICANTLY DOWNREGULATED IN INSTANCES OF LOSS OF HDAC9 FUNCTION, CEMENTING THE BRIDGING RELATIONSHIP BETWEEN HDAC9 AND MACROPHAGE POLARIZATION, WHERE THE HDAC9 WAS FOUND TO UPREGULATE M1 MACROPHAGE POLARIZATION WHICH TRANSLATED INTO THE RELEASE OF HIGHER CONTENT OF PROINFLAMMATORY CYTOKINES SUCH AS INTERLEUKIN-1BETA (IL-1BETA) AND TUMOR NECROSIS FACTOR-ALPHA (TNF-ALPHA), WHICH TEND TO SIGNIFICANTLY DECREASE FOLLOWING THE DELETION OF TLR4. HENCE, THIS STUDY REPORTS NOVEL RELATION BETWEEN EPIGENETIC CONTROL AND ATHEROSCLEROSIS, WHICH COULD PARTLY BE EXPLAINED BY HISTONE DEACETYLATION.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
3  4065  43 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
4  2801  54 FEMALE OBESITY: SHORT- AND LONG-TERM CONSEQUENCES ON THE OFFSPRING. THE WORLDWIDE PREVALENCE OF OBESITY HAS RISEN OVER THE PAST FEW DECADES AND WOMEN ARE CURRENTLY MORE LIKELY THAN EVER TO ENTER PREGNANCY OBESE. PRE-PREGNANCY OBESITY AND EXCESSIVE GESTATIONAL WEIGHT GAIN INCREASE MISCARRIAGE RATES AND OBSTETRIC AND NEONATAL COMPLICATIONS, WHICH RESULT IN A LOWER HEALTHY LIVE BIRTH RATE. IN ADDITION TO ITS NEGATIVE CONSEQUENCES FOR THE MOTHER, OBESITY HAS BEEN SHOWN TO BE AN IMPORTANT RISK FACTOR FOR CHRONIC ILLNESSES, SUCH AS CARDIOVASCULAR DISEASE, METABOLIC SYNDROME AND TYPE 2 DIABETES IN THE ADOLESCENCE AND ADULTHOOD OF THE OFFSPRING. MOREOVER, MATERNAL OBESITY CAUSES PSYCHOLOGICAL PROBLEMS, PHYSICAL DISABILITIES AND HIGHER HEALTHCARE COSTS. FETAL PROGRAMMING OF METABOLIC FUNCTION INDUCED BY OBESITY, THROUGH PHYSIOLOGICAL AND/OR EPIGENETIC MECHANISMS, MAY HAVE AN INTERGENERATIONAL EFFECT AND COULD, THUS, PERPETUATE OBESITY IN THE NEXT GENERATION. IN ORDER TO BREAK THIS VICIOUS CIRCLE AND AVOID SERIOUS SHORT- AND LONG-TERM NEGATIVE OUTCOMES FOR BOTH MOTHERS AND FETUSES, THE PREVENTION AND ADEQUATE MANAGEMENT OF OBESITY AND GESTATIONAL WEIGHT GAIN ARE ESSENTIAL.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
5  4066  37 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
6  3786  54 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	

7  2511  44 EPIGENETICS AND PREECLAMPSIA: PROGRAMMING OF FUTURE OUTCOMES. PREGNANCY IS KNOWN TO INDUCE RAPID, PROGRESSIVE, AND SUBSTANTIAL CHANGES TO THE CARDIOVASCULAR SYSTEM, ULTIMATELY FACILITATING SUCCESSFUL PREGNANCY OUTCOMES. WOMEN WHO DEVELOP HYPERTENSIVE DISORDERS DURING PREGNANCY ARE CONSIDERED TO HAVE "FAILED" THE CARDIOVASCULAR STRESS TEST OF PREGNANCY AND LIKELY REPRESENT A SUBPOPULATION WITH INADEQUATE CARDIOVASCULAR ACCOMMODATION. PREECLAMPSIA IS A SERIOUS COMPLICATION WITH A MYRIAD OF MANIFESTATIONS IN BOTH MOTHER AND OFFSPRING. THIS PREGNANCY SYNDROME IS A POLYGENIC DISEASE AND HAS NOW BEEN LINKED TO A GREATER INCIDENCE OF CARDIOVASCULAR DISEASE. MOREOVER, OFFSPRINGS BORN TO PREECLAMPTIC MOTHERS EXHIBIT AN ELEVATED RISK OF CARDIOVASCULAR DISEASE, STROKE, AND MENTAL DISORDERS DURING ADULTHOOD. THIS SUGGESTS THAT PREECLAMPSIA NOT ONLY EXPOSES THE MOTHER AND THE FETUS TO COMPLICATIONS DURING PREGNANCY BUT ALSO PROGRAMS CHRONIC DISEASES DURING ADULTHOOD IN THE OFFSPRING. THE ETIOLOGY OF PREECLAMPSIA REMAINS UNKNOWN, WITH VARIOUS THEORIES BEING SUGGESTED TO EXPLAIN ITS ORIGIN. IT IS PRIMARILY THOUGHT TO BE ASSOCIATED WITH POOR PLACENTATION AND ENTAILS EXCESSIVE MATERNAL INFLAMMATION AND ENDOTHELIAL DYSFUNCTION. IT IS WELL ESTABLISHED NOW THAT THE MATERNAL IMMUNE SYSTEM AND THE PLACENTA ARE INVOLVED IN A HIGHLY CHOREOGRAPHED CROSS TALK THAT UNDERLIES ADEQUATE SPIRAL ARTERY REMODELING REQUIRED FOR UTEROPLACENTAL PERFUSION AND FREE FLOW OF NUTRIENTS TO THE FETUS. ALTHOUGH IT IS NOT CLEAR WHETHER IMMUNOLOGICAL ALTERATIONS OCCUR EARLY DURING PREGNANCY, STUDIES HAVE PROPOSED THAT DYSREGULATED SYSTEMIC AND PLACENTAL IMMUNITY CONTRIBUTE TO IMPAIRED ANGIOGENESIS AND THE ONSET OF PREECLAMPSIA. RECENTLY EMERGED STRONG EVIDENCE SUGGESTS A POTENTIAL LINK AMONG EPIGENETICS, MICRORNAS (MIRNAS), AND PREGNANCY COMPLICATIONS. THIS CHAPTER WILL FOCUS ON IMPORTANT ASPECTS OF EPIGENETICS, IMMUNOLOGICAL ASPECTS, AND CARDIOVASCULAR AND VASCULAR REMODELING OF PREECLAMPSIA.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
8  3975  61 LONG-TERM CONSEQUENCES OF PLACENTAL VASCULAR PATHOLOGY ON THE MATERNAL AND OFFSPRING CARDIOVASCULAR SYSTEMS. OVER THE LAST THIRTY YEARS, EVIDENCE HAS BEEN ACCUMULATING THAT HYPERTENSIVE DISORDERS OF PREGNANCY (HDP) AND, SPECIFICALLY, PREECLAMPSIA (PE) PRODUCE NOT ONLY LONG-TERM EFFECTS ON THE PREGNANT WOMAN, BUT HAVE ALSO LASTING CONSEQUENCES FOR THE FETUS. AT THE CORE OF THESE CONSEQUENCES IS THE PHENOMENON KNOWN AS DEFECTIVE DEEP PLACENTATION, BEING PRESENT IN VIRTUALLY EVERY MAJOR OBSTETRICAL SYNDROME. THE PROFOUND PLACENTAL VASCULAR LESIONS CHARACTERISTIC OF THIS PATHOLOGY CAN INDUCE LONG-TERM ADVERSE CONSEQUENCES FOR THE PREGNANT WOMAN'S ENTIRE ARTERIAL SYSTEM. IN ADDITION, PLACENTAL GROWTH RESTRICTION AND FUNCTION CAN, IN TURN, CAUSE A DECREASED BLOOD SUPPLY TO THE FETUS, WITH LONG-LASTING EFFECTS. WOMEN WITH A HISTORY OF HDP HAVE AN INCREASED RISK OF CARDIOVASCULAR DISEASES (CVD) COMPARED WITH WOMEN WITH NORMAL PREGNANCIES. SPECIFICALLY, THESE SUBJECTS ARE AT A FUTURE HIGHER RISK OF: HYPERTENSION; CORONARY ARTERY DISEASE; HEART FAILURE; PERIPHERAL VASCULAR DISEASE; CEREBROVASCULAR ACCIDENTS (STROKE); CVD-RELATED MORTALITY. VASCULAR PATHOLOGY IN PREGNANCY AND CVD MAY SHARE A COMMON ETIOLOGY AND MAY HAVE COMMON RISK FACTORS, WHICH ARE UNMASKED BY THE "STRESS" OF PREGNANCY. IT IS ALSO POSSIBLE THAT THE FUTURE OCCURRENCE OF A CVD MAY BE THE CONSEQUENCE OF ENDOTHELIAL DYSFUNCTION GENERATED BY PREGNANCY-INDUCED HYPERTENSION THAT PERSISTS AFTER DELIVERY. ALTHOUGH BIOCHEMICAL AND BIOPHYSICAL MARKERS OF PE ABOUND, INFORMATION ON MARKERS FOR A COMPARATIVE EVALUATION IN THE VARIOUS GROUPS IS STILL LACKING. LONG-TERM CONSEQUENCES FOR THE FETUS ARE AN INTEGRAL PART OF THE THEORY OF A FETAL ORIGIN OF A NUMBER OF ADULT DISEASES, KNOWN AS THE BARKER HYPOTHESIS. INDEED, INTRAUTERINE MALNUTRITION AND FETAL GROWTH RESTRICTION REPRESENT SIGNIFICANT RISK FACTORS FOR THE DEVELOPMENT OF CHRONIC HYPERTENSION, DIABETES, STROKE AND DEATH FROM CORONARY ARTERY DISEASE IN ADULTS. OTHER FACTORS WILL ALSO INFLUENCE THE DEVELOPMENT LATER IN LIFE OF HYPERTENSION, CORONARY AND MYOCARDIAL DISEASE; THEY INCLUDE PARENTAL GENETIC DISPOSITION, EPIGENETIC MODIFICATIONS, ENDOTHELIAL DYSFUNCTION, CONCURRENT INTRAUTERINE EXPOSURES, AND THE LIFESTYLE OF THE AFFECTED INDIVIDUAL.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
9  3595  39 IMPLICATIONS OF MATERNAL CONDITIONS AND PREGNANCY COURSE ON OFFSPRING'S MEDICAL PROBLEMS IN ADULT LIFE. IN THE LAST DECADE, NUMEROUS EPIDEMIOLOGICAL, CLINICAL AND EXPERIMENTAL DATA SHOW THAT PERICONCEPTIONAL, PERINATAL AND POSTNATAL ENVIRONMENT DETERMINES THE OFFSPRING'S RISK FOR LATER-LIFE CHRONIC DISEASE. FOR THIS PHENOMENON, THE TERM "FETAL" OR "PERINATAL PROGRAMMING" IS USED. IN EXPOSED OFFSPRING ALREADY IN CHILDHOOD AND EARLY ADULTHOOD, METABOLIC AND CARDIOVASCULAR CHANGES CAN BE OBSERVED, LEADING TO OBESITY, DIABETES AND HYPERTENSION. NOWADAYS, THE MODE OF CONCEPTION (E.G., IN VITRO FERTILIZATION), MATERNAL METABOLIC CONDITIONS (E.G., UNDERNUTRITION, OVERNUTRITION, DIABETES) AND COMPLICATIONS DURING PREGNANCY (E.G., PREECLAMPSIA, INTRAUTERINE GROWTH RESTRICTION) ARE SUSPECTED TO BE NEGATIVE PREDICTORS FOR OFFSPRING'S LONG-TERM HEALTH. MECHANISMS RESPONSIBLE FOR THESE EFFECTS STILL REMAIN MAINLY UNCLEAR, BUT INCLUDE EPIGENETIC, TRANSCRIPTIONAL, ENDOPLASMIC RETICULUM STRESS, AND REACTIVE OXYGEN SPECIES. THIS REVIEW PRESENTS A PIECE OF THE PUZZLE WITH REGARDS TO PERICONCEPTIONAL AND EARLY PERINATAL CONDITIONS DETERMINING LATER-LIFE RISK FOR CHRONIC ADULT DISEASE.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
10  2806  51 FETAL PROGRAMMING AND THE RISK OF NONCOMMUNICABLE DISEASE. THE "DEVELOPMENTAL ORIGINS OF HEALTH AND DISEASE" (DOHAD) HYPOTHESIS PROPOSES THAT ENVIRONMENTAL CONDITIONS DURING FETAL AND EARLY POST-NATAL DEVELOPMENT INFLUENCE LIFELONG HEALTH AND CAPACITY THROUGH PERMANENT EFFECTS ON GROWTH, STRUCTURE AND METABOLISM. THIS HAS BEEN CALLED 'PROGRAMMING'. THE HYPOTHESIS IS SUPPORTED BY EPIDEMIOLOGICAL EVIDENCE IN HUMANS LINKING NEWBORN SIZE, AND INFANT GROWTH AND NUTRITION, TO ADULT HEALTH OUTCOMES, AND BY EXPERIMENTS IN ANIMALS SHOWING THAT MATERNAL UNDER- AND OVER-NUTRITION AND OTHER INTERVENTIONS (E.G., GLUCOCORTICOID EXPOSURE) DURING PREGNANCY LEAD TO ABNORMAL METABOLISM AND BODY COMPOSITION IN THE ADULT OFFSPRING. EARLY LIFE PROGRAMMING IS NOW THOUGHT TO BE IMPORTANT IN THE ETIOLOGY OF OBESITY, TYPE 2 DIABETES, AND CARDIOVASCULAR DISEASE, OPENING UP THE POSSIBILITY THAT THESE COMMON DISEASES COULD BE PREVENTED BY ACHIEVING OPTIMAL FETAL AND INFANT DEVELOPMENT. THIS IS LIKELY TO HAVE ADDITIONAL BENEFITS FOR INFANT SURVIVAL AND HUMAN CAPITAL (E.G., IMPROVED COGNITIVE PERFORMANCE AND PHYSICAL WORK CAPACITY). FETAL NUTRITION IS INFLUENCED BY THE MOTHER'S DIET AND BODY SIZE AND COMPOSITION, BUT HARD EVIDENCE THAT THE NUTRITION OF THE HUMAN MOTHER PROGRAMMES CHRONIC DISEASE RISK IN HER OFFSPRING IS CURRENTLY LIMITED. RECENT FINDINGS FROM FOLLOW-UP OF CHILDREN BORN AFTER RANDOMISED NUTRITIONAL INTERVENTIONS IN PREGNANCY ARE MIXED, BUT SHOW SOME EVIDENCE OF BENEFICIAL EFFECTS ON VASCULAR FUNCTION, LIPID CONCENTRATIONS, GLUCOSE TOLERANCE AND INSULIN RESISTANCE. WORK IN EXPERIMENTAL ANIMALS SUGGESTS THAT EPIGENETIC PHENOMENA, WHEREBY GENE EXPRESSION IS MODIFIED BY DNA METHYLATION, AND WHICH ARE SENSITIVE TO THE NUTRITIONAL ENVIRONMENT IN EARLY LIFE, MAY BE ONE MECHANISM UNDERLYING PROGRAMMING.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
11   418  48 ANCESTRAL EXPOSURE TO STRESS EPIGENETICALLY PROGRAMS PRETERM BIRTH RISK AND ADVERSE MATERNAL AND NEWBORN OUTCOMES. BACKGROUND: CHRONIC STRESS IS CONSIDERED TO BE ONE OF MANY CAUSES OF HUMAN PRETERM BIRTH (PTB), BUT NO DIRECT EVIDENCE HAS YET BEEN PROVIDED. HERE WE SHOW IN RATS THAT STRESS ACROSS GENERATIONS HAS DOWNSTREAM EFFECTS ON ENDOCRINE, METABOLIC AND BEHAVIOURAL MANIFESTATIONS OF PTB POSSIBLY VIA MICRORNA (MIRNA) REGULATION. METHODS: PREGNANT DAMS OF THE PARENTAL GENERATION WERE EXPOSED TO STRESS FROM GESTATIONAL DAYS 12 TO 18. THEIR PREGNANT DAUGHTERS (F1) AND GRAND-DAUGHTERS (F2) EITHER WERE STRESSED OR REMAINED AS NON-STRESSED CONTROLS. GESTATIONAL LENGTH, MATERNAL GESTATIONAL WEIGHT GAIN, BLOOD GLUCOSE AND PLASMA CORTICOSTERONE LEVELS, LITTER SIZE AND OFFSPRING WEIGHT GAIN FROM POSTNATAL DAYS 1 TO 30 WERE RECORDED IN EACH GENERATION, INCLUDING F3. MATERNAL BEHAVIOURS WERE ANALYSED FOR THE FIRST HOUR AFTER COMPLETED PARTURITION, AND OFFSPRING SENSORIMOTOR DEVELOPMENT WAS RECORDED ON POSTNATAL DAY (P) 7. F0 THROUGH F2 MATERNAL BRAIN FRONTAL CORTEX, UTERUS AND PLACENTA MIRNA AND GENE EXPRESSION PATTERNS WERE USED TO IDENTIFY STRESS-INDUCED EPIGENETIC REGULATORY PATHWAYS OF MATERNAL BEHAVIOUR AND PREGNANCY MAINTENANCE. RESULTS: PROGRESSIVELY UP TO THE F2 GENERATION, STRESS GRADUALLY REDUCED GESTATIONAL LENGTH, MATERNAL WEIGHT GAIN AND BEHAVIOURAL ACTIVITY, AND INCREASED BLOOD GLUCOSE LEVELS. REDUCED OFFSPRING GROWTH AND DELAYED BEHAVIOURAL DEVELOPMENT IN THE STRESS COHORT WAS RECOGNIZABLE AS EARLY AS P7, WITH THE GREATEST EFFECT IN THE F3 OFFSPRING OF TRANSGENERATIONALLY STRESSED MOTHERS. FURTHERMORE, STRESS ALTERED MIRNA EXPRESSION PATTERNS IN THE BRAIN AND UTERUS OF F2 MOTHERS, INCLUDING THE MIR-200 FAMILY, WHICH REGULATES PATHWAYS RELATED TO BRAIN PLASTICITY AND PARTURITION, RESPECTIVELY. MAIN MIR-200 FAMILY TARGET GENES IN THE UTERUS, STAT5B, ZEB1 AND ZEB2, WERE DOWNREGULATED BY MULTIGENERATIONAL STRESS IN THE F1 GENERATION. ZEB2 WAS ALSO REDUCED IN THE STRESSED F2 GENERATION, SUGGESTING A CAUSAL MECHANISM FOR DISTURBED PREGNANCY MAINTENANCE. ADDITIONALLY, STRESS INCREASED PLACENTAL MIR-181A, A MARKER OF HUMAN PTB. CONCLUSIONS: THE FINDINGS INDICATE THAT A FAMILY HISTORY OF STRESS MAY PROGRAM CENTRAL AND PERIPHERAL PATHWAYS REGULATING GESTATIONAL LENGTH AND MATERNAL AND NEWBORN HEALTH OUTCOMES IN THE MATERNAL LINEAGE. THIS NEW PARADIGM MAY MODEL THE ORIGIN OF MANY HUMAN PTB CAUSES.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
12  4202  40 METABOLIC SYNDROME IN CHILDREN BORN SMALL-FOR-GESTATIONAL AGE. BEING BORN SMALL-FOR-GESTATIONAL AGE AND A RAPID INCREASE IN WEIGHT DURING EARLY CHILDHOOD AND INFANCY HAS BEEN STRONGLY LINKED WITH CHRONIC DISEASES, INCLUDING METABOLIC SYNDROME, WHICH HAS BEEN RELATED TO INTRAUTERINE LIFE ENVIRONMENT AND LINKED TO EPIGENETIC FETAL PROGRAMMING. METABOLIC SYNDROME INCLUDES WAIST CIRCUMFERENCE >/= 90(TH) PERCENTILE FOR AGE, SEX AND RACE, HIGHER LEVELS OF BLOOD PRESSURE, TRIGLYCERIDES AND FASTING GLUCOSE, AND LOW LEVELS OF HDL-CHOLESTEROL. INSULIN RESISTANCE MAY BE PRESENT AS EARLY AS 1 YEAR OF AGE, AND OBESITY AND/OR TYPE 2 DIABETES ARE MORE PREVALENT IN THOSE BORN SGA THAN THOSE BORN AGA. THE PROGRAMMING OF ADAPTIVE RESPONSES IN CHILDREN BORN SGA INCLUDES AN ASSOCIATION WITH INCREASED BLOOD PRESSURE, CHANGES IN ENDOTHELIAL FUNCTION, ARTERIAL PROPERTIES AND CORONARY DISEASE. EARLY INTERVENTIONS SHOULD BE DIRECTED TO APPROPRIATE MATERNAL NUTRITION, BEFORE AND DURING PREGNANCY, PROMOTION OF BREAST FEEDING, AND PREVENTION OF RAPID WEIGHT GAIN DURING INFANCY, AND TO PROMOTE A HEALTHY LIFESTYLE.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
13  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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
14  4062  49 MATERNAL AND CHILD HEALTH SERVICES AND AN INTEGRATED, LIFE-CYCLE APPROACH TO THE PREVENTION OF NON-COMMUNICABLE DISEASES. DESCRIBED AS THE 'INVISIBLE EPIDEMIC', NON-COMMUNICABLE DISEASES (NCDS) ARE THE WORLD'S LEADING CAUSE OF DEATH. MOST ARE CAUSED BY PREVENTABLE FACTORS, INCLUDING POOR DIET, TOBACCO USE, HARMFUL USE OF ALCOHOL AND PHYSICAL INACTIVITY. DIABETES, CANCER AND CARDIOVASCULAR AND CHRONIC LUNG DISEASES WERE RESPONSIBLE FOR 38 MILLION (68%) OF GLOBAL DEATHS IN 2012. SINCE 1990, PROPORTIONATE NCD MORTALITY HAS INCREASED SUBSTANTIALLY AS POPULATIONS HAVE AGED AND COMMUNICABLE DISEASES DECLINE. THE MAJORITY OF NCD DEATHS, ESPECIALLY PREMATURE NCD DEATHS (<70 YEARS, 82%), OCCUR IN LOW-INCOME AND MIDDLE-INCOME COUNTRIES, AND AMONG POOR COMMUNITIES WITHIN THEM. ADDRESSING NCDS IS RECOGNISED AS CENTRAL TO THE POST-2015 AGENDA; ACCORDINGLY, NCDS HAVE A SPECIFIC OBJECTIVE AND TARGET IN THE SUSTAINABLE DEVELOPMENT GOALS. WHILE DEATHS FROM NCDS OCCUR MAINLY IN ADULTHOOD, MANY HAVE THEIR ORIGINS IN EARLY LIFE, INCLUDING THROUGH EPIGENETIC MECHANISMS OPERATING BEFORE CONCEPTION. GOOD NUTRITION BEFORE CONCEPTION AND INTERVENTIONS AIMED AT PREVENTING NCDS DURING THE FIRST 1000 DAYS (FROM CONCEPTION TO AGE 2 YEARS), CHILDHOOD AND ADOLESCENCE MAY BE MORE COST-EFFECTIVE THAN MANAGING ESTABLISHED NCDS IN LATER LIFE WITH COSTLY TESTS AND DRUGS. FOLLOWING A LIFE-COURSE APPROACH, MATERNAL AND CHILD HEALTH INTERVENTIONS, BEFORE DELIVERY AND DURING CHILDHOOD AND ADOLESCENCE, CAN PREVENT NCDS AND SHOULD INFLUENCE GLOBAL HEALTH AND SOCIOECONOMIC DEVELOPMENT. THIS PAPER DESCRIBES HOW SUCH AN APPROACH MAY BE PURSUED, INCLUDING THROUGH THE ENGAGEMENT OF NON-HEALTH SECTORS. IT ALSO EMPHASISES EVALUATING AND DOCUMENTING RELATED INITIATIVES TO UNDERWRITE SYSTEMATIC AND EVIDENCE-BASED CROSS-SECTORAL ENGAGEMENT ON NCD PREVENTION IN THE FUTURE.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
15  2805  54 FETAL MALNUTRITION AND LONG-TERM OUTCOMES. EPIDEMIOLOGICAL STUDIES HAVE SHOWN THAT LOWER BIRTHWEIGHT IS ASSOCIATED WITH A WIDE RANGE OF ADVERSE OUTCOMES IN LATER LIFE, INCLUDING POORER 'HUMAN CAPITAL' (SHORTER STATURE, LOWER COGNITIVE PERFORMANCE), INCREASED RISK FACTORS FOR LATER DISEASE (HIGHER BLOOD PRESSURE AND REDUCED GLUCOSE TOLERANCE, AND LUNG, KIDNEY AND IMMUNE FUNCTION), CLINICAL DISEASE (DIABETES, CORONARY HEART DISEASE, CHRONIC LUNG AND KIDNEY DISEASE), AND INCREASED ALL-CAUSE AND CARDIOVASCULAR MORTALITY. HIGHER BIRTHWEIGHT IS ASSOCIATED WITH AN INCREASED RISK OF CANCER AND (IF CAUSED BY GESTATIONAL DIABETES) OBESITY AND DIABETES. THE 'DEVELOPMENTAL ORIGINS OF HEALTH AND DISEASE' HYPOTHESIS PROPOSES THAT FETAL NUTRITION HAS PERMANENT EFFECTS ON GROWTH, STRUCTURE AND METABOLISM ('PROGRAMMING'). THIS IS SUPPORTED BY STUDIES IN ANIMALS SHOWING THAT MATERNAL UNDER- AND OVERNUTRITION DURING PREGNANCY CAN PRODUCE SIMILAR ABNORMALITIES IN THE ADULT OFFSPRING. COMMON CHRONIC DISEASES COULD POTENTIALLY BE PREVENTED BY ACHIEVING OPTIMAL FETAL NUTRITION, AND THIS COULD HAVE ADDITIONAL BENEFITS FOR SURVIVAL AND HUMAN CAPITAL. RECENT FOLLOW-UP OF CHILDREN BORN AFTER RANDOMIZED NUTRITIONAL INTERVENTIONS IN PREGNANCY PROVIDES WEAK EVIDENCE OF BENEFICIAL EFFECTS ON GROWTH, VASCULAR FUNCTION, LIPID CONCENTRATIONS, GLUCOSE TOLERANCE AND INSULIN RESISTANCE. ANIMAL STUDIES INDICATE THAT EPIGENETIC PHENOMENA MAY BE AN IMPORTANT MECHANISM UNDERLYING PROGRAMMING, AND THAT NUTRITIONAL INTERVENTIONS MAY NEED TO START PRECONCEPTIONALLY.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
16  6234  47 THE LONG-TERM EFFECTS OF PRENATAL DEVELOPMENT ON GROWTH AND METABOLISM. PEOPLE WHO WERE SMALL AT BIRTH AND HAD POOR INFANT GROWTH HAVE AN INCREASED RISK OF ADULT CARDIOVASCULAR DISEASE, OSTEOPOROSIS, AND TYPE 2 DIABETES, PARTICULARLY IF THEIR RESTRICTED EARLY GROWTH WAS FOLLOWED BY INCREASED CHILDHOOD WEIGHT GAIN. THESE RELATIONS EXTEND ACROSS THE NORMAL RANGE OF BIRTH SIZE IN A GRADED MANNER, SO REDUCED SIZE IS NOT A PREREQUISITE. IN ADDITION, LARGER BIRTH SIZE IS ASSOCIATED WITH RISKS OF OBESITY AND TYPE 2 DIABETES. THE ASSOCIATIONS APPEAR TO REFLECT DEVELOPMENTAL PLASTIC RESPONSES MADE BY THE FETUS AND INFANT BASED ON CUES ABOUT THE ENVIRONMENT, INFLUENCED BY MATERNAL CHARACTERISTICS INCLUDING DIET, BODY COMPOSITION, STRESS, AND EXERCISE LEVELS. THESE RESPONSES INVOLVE EPIGENETIC PROCESSES THAT MODIFY THE OFFSPRING'S PHENOTYPE. VULNERABILITY TO ILL HEALTH RESULTS IF THE ENVIRONMENT IN INFANCY, CHILDHOOD, AND LATER LIFE IS MISMATCHED TO THE PHENOTYPE INDUCED IN DEVELOPMENT, INFORMED BY THE DEVELOPMENTAL CUES.

17  6742  45 WHITHER THE ETIOPATHOGENESIS (AND SCOLIOGENY) OF ADOLESCENT IDIOPATHIC SCOLIOSIS? ALTHOUGH CONSIDERABLE PROGRESS HAD BEEN MADE IN THE PAST TWO DECADES IN UNDERSTANDING THE ETIOPATHOGENESIS OF ADOLESCENT IDIOPATHIC SCOLIOSIS (AIS), IT STILL LACKS AN AGREED THEORY OF ETIOPATHOGENESIS. ONE PROBLEM MAY BE THAT AIS RESULTS NOT FROM ONE CAUSE, BUT SEVERAL THAT INTERACT WITH VARIOUS GENETIC PREDISPOSING FACTORS. THERE IS A VIEW THERE ARE TWO OTHER PATHOGENIC PROCESSES FOR IDIOPATHIC SCOLIOSIS NAMELY, INITIATING (OR INDUCING), AND THOSE THAT CAUSE CURVE PROGRESSION. TWIN STUDIES AND OBSERVATIONS OF FAMILY AGGREGATION HAVE REVEALED SIGNIFICANT GENETIC CONTRIBUTIONS TO IDIOPATHIC SCOLIOSIS, THAT PLACE AIS AMONG OTHER COMMON DISEASE OR COMPLEX TRAITS WITH A HIGH HERITABILITY INTERPRETED BY THE GENETIC VARIANT HYPOTHESIS OF DISEASE. WE SUMMARIZE ETIOPATHOGENETIC KNOWLEDGE OF AIS AS THEORIES OF PATHOGENESIS INCLUDING RECENT MULTIPLE CONCEPTS, AND BLOOD TESTS FOR AIS BASED ON PREDICTIVE BIOMARKERS AND GENETIC VARIANTS THAT SIGNIFY DISEASE RISK. THERE IS INCREASING EVIDENCE FOR THE POSSIBILITY OF AN UNDERLYING NEUROLOGICAL DISORDER FOR AIS, RESEARCH WHICH HOLDS PROMISE. LIKE BRAIN RESEARCH, MOST AIS WORKERS FOCUS ON THEIR OWN CORNER AND THERE IS A NEED FOR GREATER INTEGRATION OF RESEARCH EFFORT. EPIGENETICS, A RELATIVELY RECENT FIELD, EVALUATES FACTORS CONCERNED WITH GENE EXPRESSION IN RELATION TO ENVIRONMENT, DISEASE, NORMAL DEVELOPMENT AND AGING, WITH A COMPLEX REGULATION ACROSS THE GENOME DURING THE FIRST DECADE OF LIFE. RESEARCH ON THE ROLE OF ENVIRONMENTAL FACTORS, EPIGENETICS AND CHRONIC NON-COMMUNICABLE DISEASES (NCDS) INCLUDING ADIPOSITY, AFTER A SLOW START, HAS EXPLODED IN THE LAST DECADE. NOT SO FOR AIS RESEARCH AND THE ENVIRONMENT WHERE, EXCEPT FOR MONOZYGOTIC TWIN STUDIES, THERE ARE ONLY SPORADIC REPORTS TO SUGGEST THAT ENVIRONMENTAL FACTORS ARE AT WORK IN ETIOLOGY. HERE, WE EXAMINE EPIGENETIC CONCEPTS AS THEY MAY RELATE TO HUMAN DEVELOPMENT, NORMAL LIFE HISTORY PHASES AND AIS PATHOGENESIS. ALTHOUGH AIS IS NOT REGARDED AS AN NCD, LIKE THEM, IT IS ASSOCIATED WITH WHOLE ORGANISM METABOLIC PHENOMENA, INCLUDING LOWER BODY MASS INDEX, LOWER CIRCULATING LEPTIN LEVELS AND OTHER SYSTEMIC DISORDERS. SOME EPIGENETIC RESEARCH APPLIED TO SILVER-RUSSELL SYNDROME AND ADIPOSITY IS EXAMINED, FROM WHICH SUGGESTIONS ARE MADE FOR CONSIDERATION OF AIS EPIGENETIC RESEARCH, CROSS-SECTIONAL AND LONGITUDINAL. THE WORD SCOLIOGENY IS SUGGESTED TO INCLUDE ETIOLOGY, PATHOGENESIS AND PATHOMECHANISM.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
18  3578  48 IMPACT OF PARENTAL OVER- AND UNDERWEIGHT ON THE HEALTH OF OFFSPRING. PARENTAL EXCESS WEIGHT AND ESPECIALLY PREGESTATIONAL MATERNAL OBESITY AND EXCESSIVE WEIGHT GAIN DURING PREGNANCY HAVE BEEN RELATED TO AN INCREASED RISK OF METABOLIC (OBESITY, TYPE 2 DIABETES, CARDIOVASCULAR DISEASE, METABOLIC SYNDROME) AND NONMETABOLIC (CANCER, OSTEOPOROSIS, ASTHMA, NEUROLOGIC ALTERATIONS) DISEASES IN THE OFFSPRING, PROBABLY MEDIATED BY EPIGENETIC MECHANISMS OF FETAL PROGRAMMING. MATERNAL UNDERWEIGHT IS LESS COMMON IN DEVELOPED SOCIETIES, BUT THE DISCREPANCY BETWEEN A POOR NUTRITIONAL ENVIRONMENT IN UTERO AND A NORMAL OR EXCESSIVE POSTNATAL FOOD SUPPLY WITH RAPID GROWTH CATCH-UP APPEARS TO BE THE MAIN CANDIDATE MECHANISM OF THE DEVELOPMENT OF CHRONIC DISEASES DURING THE OFFSPRING'S ADULTHOOD. THE ROLE OF THE POSTNATAL ENVIRONMENT IN BOTH SCENARIOS (PARENTAL OVERWEIGHT OR UNDERWEIGHT) ALSO SEEMS TO INFLUENCE THE OFFSPRING'S HEALTH. LIFESTYLE INTERVENTIONS BEFORE AND DURING PREGNANCY IN BOTH PARENTS, BUT ESPECIALLY IN THE MOTHER, AS WELL AS IN CHILDREN AFTER BIRTH, ARE ADVISABLE TO COUNTERACT THE MANY UNDESIRABLE CHRONIC CONDITIONS DESCRIBED.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
19  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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
20  4075  42 MATERNAL HIGH-FAT DIET IMPAIRS LEPTIN SIGNALING AND UP-REGULATES TYPE-1 CANNABINOID RECEPTOR WITH SEX-SPECIFIC EPIGENETIC CHANGES IN THE HYPOTHALAMUS OF NEWBORN RATS. MATERNAL NUTRITIONAL IMBALANCES TRIGGER DEVELOPMENTAL ADAPTATIONS INVOLVING EARLY EPIGENETIC MECHANISMS ASSOCIATED WITH ADULT CHRONIC DISEASE. MATERNAL HIGH-FAT (HF) DIET PROMOTES OBESITY AND HYPOTHALAMIC LEPTIN RESISTANCE IN MALE RAT OFFSPRING AT WEANING AND ADULTHOOD. LEPTIN RESISTANCE IS ASSOCIATED WITH OVER ACTIVATION OF THE ENDOCANNABINOID SYSTEM (ECS). THE ECS MAINLY CONSISTS OF ENDOCANNABINOIDS DERIVED FROM N-6 FATTY ACIDS AND CANNABINOID RECEPTORS (CB1 CODED BY CNR1 AND CB2 CODED BY CNR2). THE CB1 ACTIVATION IN HYPOTHALAMUS STIMULATES FEEDING AND APPETITE FOR FAT WHILE CB2 ACTIVATION SEEMS TO PLAY AN IMMUNOMODULATORY ROLE. WE DEMONSTRATED THAT MATERNAL HF DIET INCREASES HYPOTHALAMIC CB1 IN MALE OFFSPRING WHILE INCREASES CB2 IN FEMALE OFFSPRING AT BIRTH, PRIOR TO OBESITY DEVELOPMENT. HOWEVER, THE MOLECULAR MECHANISMS BEHIND THESE CHANGES REMAIN UNEXPLORED. WE HYPOTHESIZED THAT MATERNAL HF DIET WOULD DOWN-REGULATE LEPTIN SIGNALING AND UP-REGULATE CNR1 MRNA LEVELS IN THE HYPOTHALAMUS OF THE OFFSPRING AT BIRTH, ASSOCIATED WITH SEX-SPECIFIC CHANGES IN EPIGENETIC MARKERS AND SEX STEROID SIGNALING. TO TEST OUR HYPOTHESIS, WE USED PROGENITOR FEMALE RATS THAT RECEIVED CONTROL DIET (C, 9% FAT) OR ISOCALORIC HIGH-FAT DIET (HF, 28% FAT) FROM 8 WEEKS BEFORE MATING UNTIL DELIVERY. BLOOD, HYPOTHALAMUS AND CARCASS FROM C AND HF MALE AND FEMALE OFFSPRING WERE COLLECTED FOR BIOCHEMICAL AND MOLECULAR ANALYSES AT BIRTH. MATERNAL HF DIET DOWN-REGULATED THE TRANSCRIPTIONAL FACTOR STAT3 IN THE HYPOTHALAMUS OF MALE AND FEMALE OFFSPRING, BUT INDUCED HYPOLEPTINEMIA ONLY IN MALES AND DECREASED PHOSPHORYLATED STAT3 ONLY IN FEMALE OFFSPRING. BECAUSE LEPTIN ACTS THROUGH STAT3 PATHWAY TO INHIBIT CENTRAL ECS, OUR RESULTS SUGGEST THAT LEPTIN PATHWAY IMPAIRMENT MIGHT CONTRIBUTE TO INCREASED LEVELS OF CRN1 MRNA IN HYPOTHALAMUS OF BOTH SEX OFFSPRING. BESIDES, MATERNAL HF DIET INCREASED THE HISTONE ACETYLATION PERCENTAGE OF CNR1 PROMOTER IN MALE OFFSPRING AND INCREASED THE ANDROGEN RECEPTOR BINDING TO THE CNR1 PROMOTER, WHICH CAN CONTRIBUTE TO HIGHER EXPRESSION OF CNR1 IN NEWBORN HF OFFSPRING. MATERNAL HF DIET INCREASED PLASMA N6 TO N3 FATTY ACID RATIO IN MALE OFFSPRING, WHICH IS AN IMPORTANT RISK FACTOR TO METABOLIC DISEASES AND MIGHT INDICATE AN OVER ACTIVATION OF ENDOCANNABINOID SIGNALING. THUS, ALTHOUGH MATERNAL HF DIET PROGRAMS A SIMILAR PHENOTYPE IN ADULT OFFSPRING OF BOTH SEXES (OBESITY, HYPERPHAGIA AND HIGHER PREFERENCE FOR FAT), HERE WE SHOWED THAT MOLECULAR MECHANISMS INVOLVING LEPTIN SIGNALING, ECS, EPIGENETIC MARKERS AND SEX HORMONE SIGNALING WERE MODIFIED PRIOR TO OBESITY DEVELOPMENT AND CAN DIFFER BETWEEN NEWBORN MALE AND FEMALE OFFSPRING. THESE OBSERVATIONS MAY PROVIDE MOLECULAR INSIGHTS INTO SEX-SPECIFIC TARGETS FOR ANTI-OBESITY THERAPIES.	2019
