1  4910 135 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
2   509  34 ASSOCIATION OF NUTRACEUTICAL SUPPLEMENTS WITH LONGER TELOMERE LENGTH. TELOMERES ARE NUCLEOTIDE TANDEM REPEATS LOCATED AT THE TIP OF EUKARYOTIC CHROMOSOMES THAT MAINTAIN GENOMIC INTEGRITY. THE GRADUAL SHORTENING OF TELOMERES LEADS TO CELLULAR SENESCENCE AND APOPTOSIS, A KEY MECHANISM OF AGING AND AGE?RELATED CHRONIC DISEASES. EPIGENETIC FACTORS, SUCH AS NUTRITION, EXERCISE AND TOBACCO CAN AFFECT THE RATE AT WHICH TELOMERES SHORTEN AND CAN MODIFY THE RISK OF DEVELOPING CHRONIC DISEASES. IN THIS STUDY, WE EVALUATED THE EFFECTS OF A COMBINATION OF NUTRACEUTICAL SUPPLEMENTS (NS) ON TELOMERE LENGTH (TL) IN HEALTHY VOLUNTEERS WITH NO MEDICAL HISTORY OF ANY DISEASE. PARTICIPANTS (N=47) WERE SELECTED FROM HEALTHY OUTPATIENTS VISITING A PRIVATE CLINIC AND WERE DIVIDED INTO THE EXPERIMENTAL GROUP (N=16), THAT RECEIVED THE NS AND THE CONTROL GROUP (N=31). WE ESTIMATED THE LENGTH OF SINGLE TELOMERES IN METAPHASE SPREAD LEUKOCYTES, ISOLATED FROM PERIPHERAL BLOOD, USING QUANTITATIVE?FLUORESCENT IN SITU HYBRIDIZATION (Q?FISH) ANALYSIS. THE LENGTH OF THE WHOLE TELOMERE GENOME WAS SIGNIFICANTLY INCREASED (P<0.05) FOR THE MEAN, 1ST QUARTILE AND MEDIAN MEASUREMENTS IN THE EXPERIMENTAL GROUP. SIMILAR FINDINGS WERE OBSERVED FOR SHORT TL (20TH PERCENTILE) (P<0.05) FOR THE MEDIAN AND 3RD QUARTILE MEASUREMENTS IN THE NS GROUP, COMPARED TO THE CONTROL GROUP. THE BENEFICIAL EFFECTS OF THE SUPPLEMENTS ON THE LENGTH OF SHORT TELOMERES REMAINED SIGNIFICANT (P<0.05) FOLLOWING ADJUSTMENT FOR AGE AND SEX. TELOMERES WERE MODERATELY LONGER IN FEMALE PATIENTS COMPARED TO THE MALE PATIENTS. ON THE WHOLE, THE FINDINGS OF THIS STUDY SUGGEST THAT THE ADMINISTRATION OF NS MAY BE LINKED TO SUSTAINING THE TL.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
3  5962  34 TELOMERES, OXIDATIVE STRESS, AND TIMING FOR SPONTANEOUS TERM AND PRETERM LABOR. TELOMERES ARE NUCLEOPROTEIN COMPLEXES LOCATED AT THE DISTAL ENDS OF CHROMOSOMES. IN ADULTS, PROGRESSIVE TELOMERE SHORTENING OCCURS THROUGHOUT THE LIFETIME AND IS THOUGHT TO CONTRIBUTE TO PROGRESSIVE AGING, PHYSIOLOGICAL SENESCENCE, MULTIORGAN DYSFUNCTION, AND ULTIMATELY, DEATH. AS DISCUSSED IN THIS REVIEW, MULTIPLE LINES OF EVIDENCE PROVIDE SUPPORT FOR THE BIOLOGICAL PLAUSIBILITY THAT A TELOMERE-BASED CLOCK MECHANISM ALSO DETERMINES THE LENGTH OF GESTATION, LEADING TO THE ONSET OF LABOR (PARTURITION). AFTER TELOMERE EXPANSION AT THE BEGINNING OF PREGNANCY, THE TELOMERE LENGTHS IN THE GESTATIONAL TISSUES (IE, THE PLACENTA AND FETAL MEMBRANES) PROGRESSIVELY SHORTEN THROUGHOUT THE REMAINDER OF PREGNANCY. THE RATE OF TELOMERE SHORTENING CAN BE ACCELERATED BY CONDITIONS THAT AFFECT THE MOTHER AND RESULT IN OXIDATIVE STRESS. PRETERM BIRTHS IN THE UNITED STATES ARE ASSOCIATED WITH MULTIPLE RISK FACTORS THAT ARE LINKED WITH INCREASED OXIDATIVE STRESS. ANTIOXIDANT VITAMINS (IE, VITAMINS E AND C) MITIGATE THE EFFECTS OF OXIDATIVE STRESS AND DELAY OR PREVENT TELOMERE SHORTENING. CLINICAL TRIALS WITH VITAMINS E AND C AND WITH MULTIVITAMINS STARTED DURING THE PERICONCEPTION PERIOD HAVE BEEN ASSOCIATED WITH REDUCED RATES OF PRETERM BIRTHS. IN THE UNITED STATES, AFRICAN-AMERICAN WOMEN HAVE A 2-3-FOLD HIGHER RATE OF PRETERM BIRTH. AFRICAN-AMERICAN WOMEN HAVE MULTIPLE RISK FACTORS FOR PREMATURE BIRTH, ALL OF WHICH ARE DISTINCT AND POTENTIALLY ADDITIVE WITH REGARD TO EPIGENETIC TELOMERE SHORTENING. THE "WEATHERING EFFECT" IS THE HYPOTHESIS TO EXPLAIN THE INCREASED RATES OF CHRONIC ILLNESS, DISABILITIES, AND EARLY DEATH OBSERVED IN AFRICAN-AMERICANS. WITH REGARD TO PREGNANCY, ACCELERATED WEATHERING WITH THE ASSOCIATED TELOMERE SHORTENING IN THE GESTATIONAL TISSUES WOULD NOT ONLY EXPLAIN THE PRETERM BIRTH DISPARITY BUT COULD ALSO EXPLAIN WHY HIGHLY EDUCATED, AFFLUENT AFRICAN-AMERICAN WOMEN CONTINUE TO HAVE AN INCREASED RATE OF PRETERM BIRTH. THESE STUDIES SUGGEST THAT THE RACIAL DISPARITIES IN PRETERM BIRTH ARE POTENTIALLY MEDIATED BY TELOMERE SHORTENING PRODUCED BY LIFETIME OR EVEN GENERATIONAL EXPOSURE TO THE EFFECTS OF SYSTEMIC RACISM AND SOCIOECONOMIC MARGINALIZATION. IN CONCLUSION, THIS REVIEW PRESENTS MULTIPLE LINES OF EVIDENCE SUPPORTING A NOVEL HYPOTHESIS REGARDING THE BIOLOGICAL CLOCK MECHANISM THAT DETERMINES THE LENGTH OF PREGNANCY, AND IT OPENS THE POSSIBILITY OF NEW APPROACHES TO PREVENT OR REDUCE THE RATE OF SPONTANEOUS PRETERM BIRTH.	2022	

4  5958  56 TELOMERE LENGTH AND SALIVARY CORTISOL STRESS REACTIVITY IN VERY PRETERM INFANTS. DURING THE NEONATAL INTENSIVE CARE UNIT (NICU) STAY, VERY PRETERM (VPT) INFANTS ARE EXPOSED TO LIFE-SAVING YET PAIN-INDUCING SKIN-BREAKING PROCEDURES (I.E., NICU PAIN-RELATED STRESS) WHICH CONTRIBUTE TO THE PROGRAMMING OF HYPO-RESPONSIVE HPA AXIS DEVELOPMENT DURING THE FIRST MONTHS OF LIFE. UNFORTUNATELY, TO DATE THE MECHANISMS LINKING NICU PAIN-RELATED STRESS AND ALTERED HPA AXIS REGULATION ARE ONLY LIMITEDLY KNOWN. TELOMERE LENGTH (TL) REGULATION IS AN EPIGENETIC MECHANISM PREVIOUSLY SHOWN TO BE AFFECTED BY EARLY STRESS EXPOSURES AND CAPABLE OF ASSOCIATING WITH HPA AXIS REACTIVITY IN CHILDREN. IN VPT INFANTS, NICU PAIN-RELATED STRESS WAS FOUND TO ASSOCIATE WITH DECREASED TL FROM BIRTH TO DISCHARGE, BUT THERE IS NO EVIDENCE FOR THE ASSOCIATION BETWEEN TL AND HPA AXIS IN THESE INFANTS. IN THIS STUDY, WE PROSPECTIVELY EXAMINED THE RELATIONSHIP BETWEEN NICU PAIN-RELATED STRESS AND HPA AXIS REACTIVITY TO AN AGE-APPROPRIATE SOCIO-EMOTIONAL CONDITION (I.E., THE STILL-FACE PROCEDURE, SFP) IN HEALTHY VPT INFANTS AT 3-MONTH CORRECTED AGE. NICU PAIN-RELATED STRESS WAS COMPUTED AS THE RATIO BETWEEN THE NUMBER OF SKIN-BREAKING PROCEDURES AND LENGTH OF NICU STAY. A DIFFERENTIAL SCORE (I.E., ?TL) WAS OBTAINED SUBTRACTING TL AT BIRTH FROM TL AT DISCHARGE. A NORMALIZED (LOG10) CORTISOL REACTIVITY INDEX (CRI) WAS OBTAINED BY AVERAGING POST-STRESS (20 MIN AFTER SFP) SALIVARY CORTISOL SAMPLE ON BASELINE VALUE. A REGRESSION MODEL CONTROLLING FOR NEONATAL AND SOCIO-DEMOGRAPHIC CONFOUNDERS SHOWED THAT ?TL WAS THE ONLY SIGNIFICANT PREDICTOR OF CRI. ALTHOUGH PRELIMINARY, THESE FINDINGS CONTRIBUTE TO OUR KNOWLEDGE OF THE MECHANISMS LINKING EARLY EXPOSURES TO ADVERSITY AND LATER IN LIFE REGULATION OF THE HPA AXIS IN VPT INFANTS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
5  4917  53 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
6  1916  35 ENVIRONMENTAL AND OCCUPATIONAL EXPOSURE TO CHEMICALS AND TELOMERE LENGTH IN HUMAN STUDIES. TELOMERES ARE COMPLEXES OF TANDEM REPEATS OF DNA (5'-TTAGGG-3') AND PROTEIN THAT CAP EUKARYOTIC CHROMOSOMES AND PLAY A CRITICAL ROLE IN CHROMOSOME STABILITY. TELOMERES SHORTEN WITH AGING AND THIS PROCESS CAN BE ACCELERATED BY INCREASED OXIDATIVE STRESS AND EPISODES OF INFLAMMATION. EVIDENCE IS RAPIDLY GROWING THAT TELOMERE LENGTH (TL) MAY BE AFFECTED BY ENVIRONMENTAL CHEMICALS THAT HAVE FREQUENTLY BEEN ASSOCIATED WITH CHRONIC DISEASES. IN THIS ARTICLE, WE REVIEW THE PUBLISHED DATA ON TL IN RELATION TO ENVIRONMENTAL AND OCCUPATIONAL EXPOSURE TO SEVERAL CHEMICALS BASED ON OUR OWN AND OTHERS' STUDIES. THE ENVIRONMENTAL AND OCCUPATIONAL EXPOSURES ASSOCIATED WITH SHORTER TL INCLUDE TRAFFIC-RELATED AIR POLLUTION (IE, PARTICULATE MATTER (PM), BLACK CARBON (BC), AND BENZENE AND TOLUENE), POLYCYCLIC AROMATIC HYDROCARBONS (PAHS), N-NITROSAMINES, PESTICIDES, LEAD, EXPOSURE IN CAR MECHANICAL WORKSHOPS, AND HAZARDOUS WASTE EXPOSURE. ARSENIC, PERSISTENT ORGANIC POLLUTANTS (POPS) AND SHORT-TERM EXPOSURE TO PM ARE ASSOCIATED WITH LONGER TL. WE DISCUSS THE POSSIBLE REASONS FOR THE DIFFERENCES IN RESULTS, INCLUDING TIME- AND DOSE-RELATED ISSUES, STUDY DESIGN, AND POSSIBLE MECHANISMS INVOLVED IN TELOMERE REGULATION. WE ALSO DISCUSS THE FUTURE DIRECTIONS AND CHALLENGES FOR TL-RELATED ENVIRONMENTAL AND OCCUPATIONAL HEALTH RESEARCH, SUCH AS INVESTIGATION OF TL IN SUBPOPULATIONS OF BLOOD LEUKOCYTES, AND THE STUDY OF GENETIC AND EPIGENETIC FACTORS THAT MAY REGULATE TELOMERE INTEGRITY USING LONGITUDINAL DESIGNS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
7  5961  56 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.

8  5085  42 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
9  5214  40 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
10  6625  29 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
11  2605  21 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
12   303  27 AIR POLLUTION STRESS AND THE AGING PHENOTYPE: THE TELOMERE CONNECTION. AGING IS A COMPLEX PHYSIOLOGICAL PHENOMENON. THE QUESTION WHY SOME SUBJECTS GROW OLD WHILE REMAINING FREE FROM DISEASE WHEREAS OTHERS PREMATURELY DIE REMAINS LARGELY UNANSWERED. WE FOCUS HERE ON THE ROLE OF AIR POLLUTION IN BIOLOGICAL AGING. HALLMARKS OF AGING CAN BE GROUPED INTO THREE MAIN CATEGORIES: GENOMIC INSTABILITY, TELOMERE ATTRITION, AND EPIGENETIC ALTERATIONS LEADING TO ALTERED MITOCHONDRIAL FUNCTION AND CELLULAR SENESCENCE. AT BIRTH, THE INITIAL TELOMERE LENGTH OF A PERSON IS LARGELY DETERMINED BY ENVIRONMENTAL FACTORS. TELOMERE LENGTH SHORTENS WITH EACH CELL DIVISION AND EXPOSURE TO AIR POLLUTION AS WELL AS LOW RESIDENTIAL GREENS SPACE EXPOSURE IS ASSOCIATED WITH SHORTER TELOMERE LENGTH. RECENT STUDIES SHOW THAT THE ESTIMATED EFFECTS OF PARTICULATE AIR POLLUTION EXPOSURE ON THE TELOMERE MITOCHONDRIAL AXIS OF AGING MAY PLAY AN IMPORTANT ROLE IN CHRONIC HEALTH EFFECTS OF AIR POLLUTION. THE EXPOSOME ENCOMPASSES ALL EXPOSURES OVER AN ENTIRE LIFE. AS TELOMERES CAN BE CONSIDERED AS THE CELLULAR MEMORIES OF EXPOSURE TO OXIDATIVE STRESS AND INFLAMMATION, TELOMERE MAINTENANCE MAY BE A PROXY FOR ASSESSING THE "EXPOSOME". IF TELOMERES ARE CAUSALLY RELATED TO THE AGING PHENOTYPE AND ENVIRONMENTAL AIR POLLUTION IS AN IMPORTANT DETERMINANT OF TELOMERE LENGTH, THIS MIGHT PROVIDE NEW AVENUES FOR FUTURE PREVENTIVE STRATEGIES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
13  5957  28 TELOMERE LENGTH AND EPIGENETIC AGE ACCELERATION IN ADOLESCENTS WITH ANXIETY DISORDERS. EVIDENCE ON THE RELATIONSHIP BETWEEN GENETICS AND MENTAL HEALTH ARE FLOURISHING. HOWEVER, FEW STUDIES ARE EVALUATING EARLY BIOMARKERS THAT MIGHT LINK GENES, ENVIRONMENT, AND PSYCHOPATHOLOGY. WE AIMED TO STUDY TELOMERE LENGTH (TL) AND EPIGENETIC AGE ACCELERATION (AA) IN A COHORT OF ADOLESCENTS WITH AND WITHOUT ANXIETY DISORDERS (N = 234). WE EVALUATED A REPRESENTATIVE SUBSAMPLE OF PARTICIPANTS AT BASELINE AND AFTER 5 YEARS (N = 76) AND CATEGORIZED THEM ACCORDING TO THEIR ANXIETY DISORDER DIAGNOSIS AT BOTH TIME POINTS: (1) CONTROL GROUP (NO ANXIETY DISORDER, N = 18), (2) VARIABLE GROUP (ANXIETY DISORDER IN ONE EVALUATION, N = 38), AND (3) PERSISTENT GROUP (ANXIETY DISORDER AT BOTH TIME POINTS, N = 20). WE ASSESSED RELATIVE MEAN TL BY REAL-TIME QUANTITATIVE PCR AND DNA METHYLATION BY INFINIUM HUMANMETHYLATION450 BEADCHIP. WE CALCULATED AA USING THE HORVATH AGE ESTIMATION ALGORITHM AND ANALYZED DIFFERENCES AMONG GROUPS USING GENERALIZED LINEAR MIXED MODELS. THE PERSISTENT GROUP OF ANXIETY DISORDER DID NOT CHANGE TL OVER TIME (P = 0.495). THE VARIABLE GROUP HAD HIGHER BASELINE TL (P = 0.003) BUT NO ACCELERATED TL EROSION IN COMPARISON TO THE NON-ANXIETY CONTROL GROUP (P = 0.053). FURTHERMORE, THERE WERE NO DIFFERENCES IN AA AMONG GROUPS OVER TIME. OUR FINDINGS SUGGEST THAT ADOLESCENTS WITH CHRONIC ANXIETY DID NOT CHANGE TELOMERE LENGTH OVER TIME, WHICH COULD BE RELATED TO A DELAY IN NEURONAL DEVELOPMENT IN THIS PERIOD OF LIFE.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
14  5959  24 TELOMERE LENGTH AS A MARKER OF BIOLOGICAL AGE: STATE-OF-THE-ART, OPEN ISSUES, AND FUTURE PERSPECTIVES. TELOMERE SHORTENING IS A WELL-KNOWN HALLMARK OF BOTH CELLULAR SENESCENCE AND ORGANISMAL AGING. AN ACCELERATED RATE OF TELOMERE ATTRITION IS ALSO A COMMON FEATURE OF AGE-RELATED DISEASES. THEREFORE, TELOMERE LENGTH (TL) HAS BEEN RECOGNIZED FOR A LONG TIME AS ONE OF THE BEST BIOMARKERS OF AGING. RECENT RESEARCH FINDINGS, HOWEVER, INDICATE THAT TL PER SE CAN ONLY ALLOW A ROUGH ESTIMATE OF AGING RATE AND CAN HARDLY BE REGARDED AS A CLINICALLY IMPORTANT RISK MARKER FOR AGE-RELATED PATHOLOGIES AND MORTALITY. EVIDENCE IS OBTAINED THAT OTHER INDICATORS SUCH AS CERTAIN IMMUNE PARAMETERS, INDICES OF EPIGENETIC AGE, ETC., COULD BE STRONGER PREDICTORS OF THE HEALTH STATUS AND THE RISK OF CHRONIC DISEASE. HOWEVER, DESPITE THESE ISSUES AND LIMITATIONS, TL REMAINS TO BE VERY INFORMATIVE MARKER IN ACCESSING THE BIOLOGICAL AGE WHEN USED ALONG WITH OTHER MARKERS SUCH AS INDICES OF HOMEOSTATIC DYSREGULATION, FRAILTY INDEX, EPIGENETIC CLOCK, ETC. THIS REVIEW ARTICLE IS AIMED AT DESCRIBING THE CURRENT STATE OF THE ART IN THE FIELD AND AT DISCUSSING RECENT RESEARCH FINDINGS AND DIVERGENT VIEWPOINTS REGARDING THE USEFULNESS OF LEUKOCYTE TL FOR ESTIMATING THE HUMAN BIOLOGICAL AGE.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
15   648  34 BIRTH WEIGHT AND MATERNAL ENERGY STATUS DURING PREGNANCY AS PREDICTORS OF EPIGENETIC AGE ACCELERATION IN YOUNG ADULTS FROM METROPOLITAN CEBU, PHILIPPINES. EPIGENETIC CLOCKS QUANTIFY REGULAR CHANGES IN DNA METHYLATION THAT OCCUR WITH AGE, OR IN RELATION TO BIOMARKERS OF AGEING, AND ARE STRONG PREDICTORS OF MORBIDITY AND MORTALITY. HERE, WE ASSESS WHETHER MEASURES OF FETAL NUTRITION AND GROWTH THAT PREDICT ADULT CHRONIC DISEASE ALSO PREDICT ACCELERATED BIOLOGICAL AGEING IN YOUNG ADULTHOOD USING A SUITE OF COMMONLY USED EPIGENETIC CLOCKS. DATA COME FROM THE CEBU LONGITUDINAL HEALTH AND NUTRITION SURVEY (CLHNS), A LONG-RUNNING COHORT FOLLOWED SINCE BIRTH IN METROPOLITAN CEBU, PHILIPPINES. PAST WORK HAS SHOWN THAT BIRTH WEIGHT (BW) AND THE MOTHER'S ARM FAT DURING PREGNANCY (A MEASURE OF PREGNANCY ENERGY STATUS) RELATE INVERSELY TO HEALTH OUTCOMES IN THE CLHNS BUT PRIMARILY IN MALES. GENOME-WIDE DNA METHYLATION WAS ASSESSED IN WHOLE BLOOD USING THE INFINIUM EPIC ARRAY. PARTICIPANTS INCLUDED MALES (N=895) AND FEMALES (N=803) MEASURED IN 2005 (20.8-22.5 YEARS). CLOCKS INCLUDED THE HANNUM AND HORVATH CLOCKS TRAINED ON CHRONOLOGICAL AGE, THE DNAMPHENOAGE AND DNAMGRIMAGE CLOCKS TRAINED ON CLINICAL BIOMARKERS, THE DUNEDIN PACE OF AGEING (DUNEDINPACE) CLOCK TRAINED ON LONGITUDINAL CHANGES IN AGEING BIOMARKERS, AND THE DNAMTL CLOCK TRAINED ON LEUKOCYTE TELOMERE LENGTH. IN MALES, LOWER BW PREDICTED ADVANCED BIOLOGICAL AGEING USING THE HANNUM, DNAMPHENOAGE, DUNEDINPOAM, AND DNAMTL CLOCKS. IN CONTRAST, BW DID NOT PREDICT ANY CLOCK IN FEMALE PARTICIPANTS. PARTICIPANTS' MOTHERS' PREGNANCY ARM FAT ONLY PREDICTED DNAMTL IN MALES. THESE FINDINGS SUGGEST THAT EPIGENETIC CLOCKS ARE A USEFUL TOOL FOR GAUGING LONG-TERM OUTCOMES PREDICTED BY FETAL GROWTH, AND ADD TO EXISTING EVIDENCE IN THE CLHNS FOR SEX DIFFERENCES IN THESE RELATIONSHIPS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
16  5683  29 SHORTER TELOMERE LENGTH IN PERIPHERAL BLOOD LYMPHOCYTES OF WORKERS EXPOSED TO POLYCYCLIC AROMATIC HYDROCARBONS. SHORTER TELOMERE LENGTH (TL) IN PERIPHERAL BLOOD LYMPHOCYTES (PBLS) IS PREDICTIVE OF LUNG CANCER RISK. POLYCYCLIC AROMATIC HYDROCARBONS (PAHS) ARE ESTABLISHED LUNG CARCINOGENS THAT CAUSE CHROMOSOME INSTABILITY. WHETHER PAH EXPOSURE AND ITS MOLECULAR EFFECTS ARE LINKED WITH SHORTER TL HAS NEVER BEEN EVALUATED. IN THE PRESENT STUDY, WE INVESTIGATED THE EFFECT OF CHRONIC EXPOSURE TO PAHS ON TL MEASURED IN PBLS OF POLISH MALE NON-CURRENT SMOKING COKEOVEN WORKERS AND MATCHED CONTROLS. PAH EXPOSURE AND MOLECULAR EFFECTS WERE CHARACTERIZED USING MEASURES OF INTERNAL DOSE (URINARY 1-PYRENOL), EFFECTIVE DOSE [ANTI-BENZO[A]PYRENE DIOLEPOXIDE (ANTI-BPDE)-DNA ADDUCT], GENETIC INSTABILITY (MICRONUCLEI, MN) AND DNA METHYLATION [P53 PROMOTER AND ALU AND LONG INTERSPERSED NUCLEAR ELEMENT-1 (LINE-1) REPETITIVE ELEMENTS, AS SURROGATE MEASURES OF GLOBAL METHYLATION] IN PBLS. TL WAS MEASURED BY REAL-TIME POLYMERASE CHAIN REACTION. COKEOVEN WORKERS WERE HEAVILY EXPOSED TO PAHS (79% EXCEEDED THE URINARY 1-PYRENOL BIOLOGICAL EXPOSURE INDEX) AND EXHIBITED LOWER TL (P = 0.038) THAN CONTROLS, AS WELL AS HIGHER LEVELS OF GENETIC AND CHROMOSOMAL ALTERATIONS [I.E. ANTI-BPDE-DNA ADDUCT AND MN (P < 0.0001)] AND EPIGENETIC CHANGES [I.E. P53 GENE-SPECIFIC PROMOTER AND GLOBAL METHYLATION (P <OR= 0.001)]. TL DECREASED WITH LONGER DURATION OF WORK AS COKEOVEN WORKER (P = 0.039) AND IN ALL SUBJECTS WITH HIGHER LEVELS OF ANTI-BPDE-DNA ADDUCT (P = 0.042), P53 HYPOMETHYLATION (P = 0.005) AND MN (P = 0.009). IN MULTIVARIATE ANALYSIS, YEARS OF WORK IN COKERY (P = 0.008) AND P53 HYPOMETHYLATION (P = 0.001) WERE THE PRINCIPAL DETERMINANTS OF SHORTER TL. OUR RESULTS INDICATE THAT SHORTER TL IS ASSOCIATED WITH CHRONIC PAH EXPOSURE. THE INTERRELATIONS WITH OTHER GENETIC AND EPIGENETIC MECHANISMS IN OUR DATA SUGGEST THAT SHORTER TL COULD BE A CENTRAL EVENT IN PAH CARCINOGENESIS.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
17   363  29 AMBIENT AIR POLLUTION: HEALTH HAZARDS TO CHILDREN. AMBIENT AIR POLLUTION IS PRODUCED BY SOURCES INCLUDING VEHICULAR TRAFFIC, COAL-FIRED POWER PLANTS, HYDRAULIC FRACTURING, AGRICULTURAL PRODUCTION, AND FOREST FIRES. IT CONSISTS OF PRIMARY POLLUTANTS GENERATED BY COMBUSTION AND SECONDARY POLLUTANTS FORMED IN THE ATMOSPHERE FROM PRECURSOR GASES. AIR POLLUTION CAUSES AND EXACERBATES CLIMATE CHANGE, AND CLIMATE CHANGE WORSENS HEALTH EFFECTS OF AIR POLLUTION. INFANTS AND CHILDREN ARE UNIQUELY SENSITIVE TO AIR POLLUTION, BECAUSE THEIR ORGANS ARE DEVELOPING AND THEY HAVE HIGHER AIR PER BODY WEIGHT INTAKE. HEALTH EFFECTS LINKED TO AIR POLLUTION INCLUDE NOT ONLY EXACERBATIONS OF RESPIRATORY DISEASES BUT ALSO REDUCED LUNG FUNCTION DEVELOPMENT AND INCREASED ASTHMA INCIDENCE. ADDITIONAL OUTCOMES OF CONCERN INCLUDE PRETERM BIRTH, LOW BIRTH WEIGHT, NEURODEVELOPMENTAL DISORDERS, IQ LOSS, PEDIATRIC CANCERS, AND INCREASED RISKS FOR ADULT CHRONIC DISEASES. THESE EFFECTS ARE MEDIATED BY OXIDATIVE STRESS, CHRONIC INFLAMMATION, ENDOCRINE DISRUPTION, AND GENETIC AND EPIGENETIC MECHANISMS ACROSS THE LIFE SPAN. NATURAL EXPERIMENTS DEMONSTRATE THAT WITH INITIATIVES SUCH AS INCREASED USE OF PUBLIC TRANSPORTATION, BOTH AIR QUALITY AND COMMUNITY HEALTH IMPROVE. SIMILARLY, THE CLEAN AIR ACT HAS IMPROVED AIR QUALITY, ALTHOUGH EXPOSURE INEQUITIES PERSIST. OTHER EFFECTIVE STRATEGIES FOR REDUCING AIR POLLUTION INCLUDE ENDING RELIANCE ON COAL, OIL, AND GAS; REGULATING INDUSTRIAL EMISSIONS; REDUCING EXPOSURE WITH ATTENTION TO PROXIMITY OF RESIDENCES, SCHOOLS, AND CHILD CARE FACILITIES TO TRAFFIC; AND A GREATER AWARENESS OF THE AIR QUALITY INDEX. THIS POLICY REVIEWS BOTH SHORT- AND LONG-TERM HEALTH CONSEQUENCES OF AMBIENT AIR POLLUTION, ESPECIALLY IN RELATION TO DEVELOPMENTAL EXPOSURES. IT EXAMINES INDIVIDUAL, COMMUNITY, AND LEGISLATIVE STRATEGIES TO MITIGATE AIR POLLUTION.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
18  3577  33 IMPACT OF NUTRITION ON TELOMERE HEALTH: SYSTEMATIC REVIEW OF OBSERVATIONAL COHORT STUDIES AND RANDOMIZED CLINICAL TRIALS. DIET, PHYSICAL ACTIVITY, AND OTHER LIFESTYLE FACTORS HAVE BEEN IMPLICATED IN THE PATHOPHYSIOLOGY OF SEVERAL CHRONIC DISEASES, BUT ALSO IN A LOWER TOTAL MORTALITY AND LONGER LIFE EXPECTANCY. ONE OF THE MECHANISMS IN WHICH DIET CAN REDUCE THE RISK OF DISEASE IS WITH REGARD TO ITS IMPACT ON TELOMERES. TELOMERE LENGTH (TL) IS HIGHLY CORRELATED TO CHRONOLOGICAL AGE AND METABOLIC STATUS. INDIVIDUALS WITH SHORTER TELOMERES ARE AT HIGHER RISK OF CHRONIC DISEASES AND MORTALITY. DIET MAY INFLUENCE TL BY SEVERAL MECHANISMS SUCH AS REGULATING OXIDATIVE STRESS AND INFLAMMATION OR MODULATING EPIGENETIC REACTIONS. THE PRESENT SYSTEMATIC REVIEW AIMS TO EXAMINE THE RESULTS FROM EPIDEMIOLOGIC AND CLINICAL TRIALS CONDUCTED IN HUMANS EVALUATING THE ROLE OF NUTRIENTS, FOOD GROUPS, AND DIETARY PATTERNS ON TL. WE ALSO DISCUSS THE POSSIBLE MECHANISMS OF ACTION THAT INFLUENCE THIS PROCESS, WITH THE PERSPECTIVE THAT TL COULD BE A NOVEL BIOMARKER INDICATING THE RISK OF METABOLIC DISTURBANCES AND AGE-RELATED DISEASES. THE AVAILABLE EVIDENCE SUGGESTS THAT SOME ANTIOXIDANT NUTRIENTS, THE CONSUMPTION OF FRUITS AND VEGETABLES, AND MEDITERRANEAN DIET ARE MAINLY ASSOCIATED WITH LONGER TELOMERES. HOWEVER, MOST OF THE EVIDENCE IS BASED ON HIGH HETEROGENIC OBSERVATIONAL STUDIES AND VERY FEW RANDOMIZED CLINICAL TRIALS (RCTS). THEREFORE, THE ASSOCIATIONS SUMMARIZED IN THE PRESENT REVIEW NEED TO BE CONFIRMED WITH LARGER PROSPECTIVE COHORT STUDIES AND BETTER-DESIGNED RCTS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
19  3664  33 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
20   529  24 ASTHMA IN URBAN CHILDREN: EPIDEMIOLOGY, ENVIRONMENTAL RISK FACTORS, AND THE PUBLIC HEALTH DOMAIN. ASTHMA IS THE MOST COMMONLY REPORTED CHRONIC CONDITION OF CHILDHOOD IN DEVELOPED COUNTRIES, WITH 6.5 MILLION CHILDREN AFFECTED IN THE USA. A DISPARATE BURDEN OF CHILDHOOD ASTHMA IS SEEN AMONG SOCIOECONOMICALLY DISADVANTAGED YOUTH, OFTEN CONCENTRATED IN URBAN AREAS WITH HIGH POVERTY RATES. HOST FACTORS THAT PREDISPOSE A CHILD TO ASTHMA INCLUDE ATOPY, MALE GENDER, PARENTAL HISTORY OF ASTHMA, AND ALSO RACE, ETHNICITY, AND GENETIC AND EPIGENETIC SUSCEPTIBILITIES. ENVIRONMENTAL FACTORS, SUCH AS IMPROVED HYGIENE, AMBIENT AIR POLLUTION, AND EARLY LIFE EXPOSURES TO MICROBES AND AEROALLERGENS, ALSO INFLUENCE THE DEVELOPMENT OF ASTHMA. WITH GREATER THAN 90% OF TIME SPENT INDOORS, HOME EXPOSURES (SUCH AS COCKROACH, RODENT, AND INDOOR AIR POLLUTION) ARE HIGHLY RELEVANT FOR URBAN ASTHMA. MORBIDITY REDUCTION MAY REQUIRE FOCUSED PUBLIC HEALTH INITIATIVES FOR ENVIRONMENTAL INTERVENTION IN HIGH PRIORITY RISK GROUPS AND THE ADDITION OF IMMUNE MODULATORY AGENTS IN CHILDREN WITH POORLY CONTROLLED DISEASE.	2016
