1  6112 160 THE EPIGENETIC CLOCK AS A PREDICTOR OF DISEASE AND MORTALITY RISK: A SYSTEMATIC REVIEW AND META-ANALYSIS. BACKGROUND: AGEING IS ONE OF THE PRINCIPAL RISK FACTORS FOR MANY CHRONIC DISEASES. HOWEVER, THERE IS CONSIDERABLE BETWEEN-PERSON VARIATION IN THE RATE OF AGEING AND INDIVIDUAL DIFFERENCES IN THEIR SUSCEPTIBILITY TO DISEASE AND DEATH. EPIGENETIC MECHANISMS MAY PLAY A ROLE IN HUMAN AGEING, AND DNA METHYLATION AGE BIOMARKERS MAY BE GOOD PREDICTORS OF AGE-RELATED DISEASES AND MORTALITY RISK. THE AIMS OF THIS SYSTEMATIC REVIEW WERE TO IDENTIFY AND SYNTHESISE THE EVIDENCE FOR AN ASSOCIATION BETWEEN PERIPHERALLY MEASURED DNA METHYLATION AGE AND LONGEVITY, AGE-RELATED DISEASE, AND MORTALITY RISK. METHODS: A SYSTEMATIC SEARCH WAS CONDUCTED IN LINE WITH THE PREFERRED REPORTING ITEMS FOR SYSTEMATIC REVIEWS AND META-ANALYSES (PRISMA) GUIDELINES. USING RELEVANT SEARCH TERMS, MEDLINE, EMBASE, COCHRANE CENTRAL REGISTER OF CONTROLLED TRIALS, AND PSYCHINFO DATABASES WERE SEARCHED TO IDENTIFY ARTICLES MEETING THE INCLUSION CRITERIA. STUDIES WERE ASSESSED FOR BIAS USING JOANNA BRIGGS INSTITUTE CRITICAL APPRAISAL CHECKLISTS. DATA WAS EXTRACTED FROM STUDIES MEASURING AGE ACCELERATION AS A PREDICTOR OF AGE-RELATED DISEASES, MORTALITY OR LONGEVITY, AND THE FINDINGS FOR SIMILAR OUTCOMES COMPARED. USING REVIEW MANAGER 5.3 SOFTWARE, TWO META-ANALYSES (ONE PER EPIGENETIC CLOCK) WERE CONDUCTED ON STUDIES MEASURING ALL-CAUSE MORTALITY. RESULTS: TWENTY-THREE RELEVANT ARTICLES WERE IDENTIFIED, INCLUDING A TOTAL OF 41,607 PARTICIPANTS. FOUR STUDIES FOCUSED ON AGEING AND LONGEVITY, 11 ON AGE-RELATED DISEASE (CANCER, CARDIOVASCULAR DISEASE, AND DEMENTIA), AND 11 ON MORTALITY. THERE WAS SOME, ALTHOUGH INCONSISTENT, EVIDENCE FOR AN ASSOCIATION BETWEEN INCREASED DNA METHYLATION AGE AND RISK OF DISEASE. META-ANALYSES INDICATED THAT EACH 5-YEAR INCREASE IN DNA METHYLATION AGE WAS ASSOCIATED AN 8 TO 15% INCREASED RISK OF MORTALITY. CONCLUSION: DUE TO THE SMALL NUMBER OF STUDIES AND HETEROGENEITY IN STUDY DESIGN AND OUTCOMES, THE ASSOCIATION BETWEEN DNA METHYLATION AGE AND AGE-RELATED DISEASE AND LONGEVITY IS INCONCLUSIVE. INCREASED EPIGENETIC AGE WAS ASSOCIATED WITH MORTALITY RISK, BUT POSITIVE PUBLICATION BIAS NEEDS TO BE CONSIDERED. FURTHER RESEARCH IS NEEDED TO DETERMINE THE EXTENT TO WHICH DNA METHYLATION AGE CAN BE USED AS A CLINICAL BIOMARKER.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
2  5085  38 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
3  5395  42 REDUCED EPIGENETIC AGE IN OLDER ADULTS WITH HIGH SENSE OF PURPOSE IN LIFE. PSYCHOSOCIAL RISK FACTORS HAVE BEEN LINKED WITH ACCELERATED EPIGENETIC AGING, BUT LITTLE IS KNOWN ABOUT WHETHER PSYCHOSOCIAL RESILIENCE FACTORS (EG, SENSE OF PURPOSE IN LIFE) MIGHT REDUCE EPIGENETIC AGE ACCELERATION. IN THIS STUDY, WE TESTED IF OLDER ADULTS WHO EXPERIENCE HIGH LEVELS OF PURPOSE MIGHT SHOW REDUCED EPIGENETIC AGE ACCELERATION. WE EVALUATED THE RELATIONSHIP BETWEEN PURPOSE AND EPIGENETIC AGE ACCELERATION AS MEASURED BY 13 DNA METHYLATION (DNAM) "EPIGENETIC CLOCKS" ASSESSED IN 1 572 OLDER ADULTS FROM THE HEALTH AND RETIREMENT STUDY (MEAN AGE 70 YEARS). WE QUANTIFIED THE TOTAL ASSOCIATION BETWEEN PURPOSE AND DNAM AGE ACCELERATION AS WELL AS THE EXTENT TO WHICH THAT TOTAL ASSOCIATION MIGHT BE ATTRIBUTABLE TO DEMOGRAPHIC FACTORS, CHRONIC DISEASE, OTHER PSYCHOSOCIAL VARIABLES (EG, POSITIVE AFFECT), AND HEALTH-RELATED BEHAVIORS (HEAVY DRINKING, SMOKING, PHYSICAL ACTIVITY, AND BODY MASS INDEX [BMI]). PURPOSE IN LIFE WAS ASSOCIATED WITH REDUCED EPIGENETIC AGE ACCELERATION ACROSS 4 "SECOND-GENERATION" DNAM CLOCKS OPTIMIZED FOR PREDICTING HEALTH AND LONGEVITY (FALSE DISCOVERY RATE [FDR] Q < 0.0001: PHENOAGE, GRIMAGE, ZHANG EPIGENETIC MORTALITY INDEX; FDR Q < 0.05: DUNEDINPOAM). THESE ASSOCIATIONS WERE INDEPENDENT OF DEMOGRAPHIC AND PSYCHOSOCIAL FACTORS, BUT SUBSTANTIALLY ATTENUATED AFTER ADJUSTING FOR HEALTH-RELATED BEHAVIORS (DRINKING, SMOKING, PHYSICAL ACTIVITY, AND BMI). PURPOSE SHOWED NO SIGNIFICANT ASSOCIATION WITH 9 "FIRST-GENERATION" DNAM EPIGENETIC CLOCKS TRAINED ON CHRONOLOGICAL AGE. OLDER ADULTS WITH GREATER PURPOSE IN LIFE SHOW "YOUNGER" DNAM EPIGENETIC AGE ACCELERATION. THESE RESULTS MAY BE DUE IN PART TO ASSOCIATED DIFFERENCES IN HEALTH-RELATED BEHAVIORS. RESULTS SUGGEST NEW OPPORTUNITIES TO REDUCE BIOLOGICAL AGE ACCELERATION BY ENHANCING PURPOSE AND ITS BEHAVIORAL SEQUELAE IN LATE ADULTHOOD.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
4  2485  36 EPIGENETIC-BASED AGE ACCELERATION IN A REPRESENTATIVE SAMPLE OF OLDER AMERICANS: ASSOCIATIONS WITH AGING-RELATED MORBIDITY AND MORTALITY. BIOMARKERS DEVELOPED FROM DNA METHYLATION (DNAM) DATA ARE OF GROWING INTEREST AS PREDICTORS OF HEALTH OUTCOMES AND MORTALITY IN OLDER POPULATIONS. HOWEVER, IT IS UNKNOWN HOW EPIGENETIC AGING FITS WITHIN THE CONTEXT OF KNOWN SOCIOECONOMIC AND BEHAVIORAL ASSOCIATIONS WITH AGING-RELATED HEALTH OUTCOMES IN A LARGE, POPULATION-BASED, AND DIVERSE SAMPLE. THIS STUDY USES DATA FROM A REPRESENTATIVE, PANEL STUDY OF US OLDER ADULTS TO EXAMINE THE RELATIONSHIP BETWEEN DNAM-BASED AGE ACCELERATION MEASURES IN THE PREDICTION OF CROSS-SECTIONAL AND LONGITUDINAL HEALTH OUTCOMES AND MORTALITY. WE EXAMINE WHETHER RECENT IMPROVEMENTS TO THESE SCORES, USING PRINCIPAL COMPONENT (PC)-BASED MEASURES DESIGNED TO REMOVE SOME OF THE TECHNICAL NOISE AND UNRELIABILITY IN MEASUREMENT, IMPROVE THE PREDICTIVE CAPABILITY OF THESE MEASURES. WE ALSO EXAMINE HOW WELL DNAM-BASED MEASURES PERFORM AGAINST WELL-KNOWN PREDICTORS OF HEALTH OUTCOMES SUCH AS DEMOGRAPHICS, SES, AND HEALTH BEHAVIORS. IN OUR SAMPLE, AGE ACCELERATION CALCULATED USING "SECOND AND THIRD GENERATION CLOCKS," PHENOAGE, GRIMAGE, AND DUNEDINPACE, IS CONSISTENTLY A SIGNIFICANT PREDICTOR OF HEALTH OUTCOMES INCLUDING CROSS-SECTIONAL COGNITIVE DYSFUNCTION, FUNCTIONAL LIMITATIONS AND CHRONIC CONDITIONS ASSESSED 2 Y AFTER DNAM MEASUREMENT, AND 4-Y MORTALITY. PC-BASED EPIGENETIC AGE ACCELERATION MEASURES DO NOT SIGNIFICANTLY CHANGE THE RELATIONSHIP OF DNAM-BASED AGE ACCELERATION MEASURES TO HEALTH OUTCOMES OR MORTALITY COMPARED TO EARLIER VERSIONS OF THESE MEASURES. WHILE THE USEFULNESS OF DNAM-BASED AGE ACCELERATION AS A PREDICTOR OF LATER LIFE HEALTH OUTCOMES IS QUITE CLEAR, OTHER FACTORS SUCH AS DEMOGRAPHICS, SES, MENTAL HEALTH, AND HEALTH BEHAVIORS REMAIN EQUALLY, IF NOT MORE ROBUST, PREDICTORS OF LATER LIFE OUTCOMES.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
5  5175  30 PREDICTORS OF BIOLOGICAL AGE: THE IMPLICATIONS FOR WELLNESS AND AGING RESEARCH. AS HEALTHSPAN AND LIFESPAN RESEARCH BREAKTHROUGHS HAVE BECOME MORE COMMONPLACE, THE NEED FOR VALID, PRACTICAL MARKERS OF BIOLOGICAL AGE IS BECOMING INCREASINGLY PARAMOUNT. THE ACCESSIBILITY AND AFFORDABILITY OF BIOLOGICAL AGE PREDICTORS THAT CAN REVEAL INFORMATION ABOUT MORTALITY AND MORBIDITY RISK, AS WELL AS REMAINING YEARS OF LIFE, HAS PROFOUND CLINICAL AND RESEARCH IMPLICATIONS. IN THIS REVIEW, WE EXAMINE 5 GROUPS OF AGING BIOMARKERS CAPABLE OF PROVIDING ACCURATE BIOLOGICAL AGE ESTIMATIONS. THE UNIQUE CAPABILITIES OF THESE BIOMARKERS HAVE FAR REACHING IMPLICATIONS FOR THE TESTING OF BOTH PHARMACEUTICAL AND NON-PHARMACEUTICAL INTERVENTIONS DESIGNED TO SLOW OR REVERSE BIOLOGICAL AGING. ADDITIONALLY, THE ENHANCED VALIDITY AND AVAILABILITY OF THESE TOOLS MAY HAVE INCREASINGLY RELEVANT CLINICAL VALUE. THE AUTHORS OF THIS REVIEW EXPLORE THOSE IMPLICATIONS, WITH AN EMPHASIS ON LIFESTYLE MODIFICATION RESEARCH, AND PROVIDE AN OVERVIEW OF THE CURRENT EVIDENCE REGARDING 5 BIOLOGICAL AGE PREDICTOR CATEGORIES: TELOMERE LENGTH, COMPOSITE BIOMARKERS, DNA METHYLATION "EPIGENETIC CLOCKS," TRANSCRIPTIONAL PREDICTORS OF BIOLOGICAL AGE, AND FUNCTIONAL AGE PREDICTORS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
6  4609  35 NEONATAL DNA METHYLATION AND CHILDHOOD LOW PROSOCIAL BEHAVIOR: AN EPIGENOME-WIDE ASSOCIATION META-ANALYSIS. LOW PROSOCIAL BEHAVIOR IN CHILDHOOD HAS BEEN CONSISTENTLY LINKED TO LATER PSYCHOPATHOLOGY, WITH EVIDENCE SUPPORTING THE INFLUENCE OF BOTH GENETIC AND ENVIRONMENTAL FACTORS ON ITS DEVELOPMENT. ALTHOUGH NEONATAL DNA METHYLATION (DNAM) HAS BEEN FOUND TO PROSPECTIVELY ASSOCIATE WITH A RANGE OF PSYCHOLOGICAL TRAITS IN CHILDHOOD, ITS POTENTIAL ROLE IN PROSOCIAL DEVELOPMENT HAS YET TO BE INVESTIGATED. THIS STUDY INVESTIGATED PROSPECTIVE ASSOCIATIONS BETWEEN CORD BLOOD DNAM AT BIRTH AND LOW PROSOCIAL BEHAVIOR WITHIN AND ACROSS FOUR LONGITUDINAL BIRTH COHORTS FROM THE PREGNANCY AND CHILDHOOD EPIGENETICS (PACE) CONSORTIUM. WE EXAMINED (A) DEVELOPMENTAL TRAJECTORIES OF "CHRONIC-LOW" VERSUS "TYPICAL" PROSOCIAL BEHAVIOR ACROSS CHILDHOOD IN A CASE-CONTROL DESIGN (N = 2,095), AND (B) CONTINUOUS "LOW PROSOCIAL" SCORES AT COMPARABLE CROSS-COHORT TIME-POINTS (N = 2,121). META-ANALYSES WERE PERFORMED TO EXAMINE DIFFERENTIALLY METHYLATED POSITIONS AND REGIONS. AT THE COHORT-SPECIFIC LEVEL, THREE CPGS WERE FOUND TO ASSOCIATE WITH CHRONIC LOW PROSOCIAL BEHAVIOR; HOWEVER, NONE OF THESE ASSOCIATIONS WAS REPLICATED IN ANOTHER COHORT. META-ANALYSIS REVEALED NO EPIGENOME-WIDE SIGNIFICANT CPGS OR REGIONS. OVERALL, WE FOUND NO EVIDENCE FOR ASSOCIATIONS BETWEEN DNAM PATTERNS AT BIRTH AND LOW PROSOCIAL BEHAVIOR ACROSS CHILDHOOD. FINDINGS HIGHLIGHT THE IMPORTANCE OF EMPLOYING MULTI-COHORT APPROACHES TO REPLICATE EPIGENETIC ASSOCIATIONS AND REDUCE THE RISK OF FALSE POSITIVE DISCOVERIES.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
7  2150  47 EPIGENETIC MEASURES OF AGEING PREDICT THE PREVALENCE AND INCIDENCE OF LEADING CAUSES OF DEATH AND DISEASE BURDEN. BACKGROUND: INDIVIDUALS OF THE SAME CHRONOLOGICAL AGE DISPLAY DIFFERENT RATES OF BIOLOGICAL AGEING. A NUMBER OF MEASURES OF BIOLOGICAL AGE HAVE BEEN PROPOSED WHICH HARNESS AGE-RELATED CHANGES IN DNA METHYLATION PROFILES. THESE MEASURES INCLUDE FIVE 'EPIGENETIC CLOCKS' WHICH PROVIDE AN INDEX OF HOW MUCH AN INDIVIDUAL'S BIOLOGICAL AGE DIFFERS FROM THEIR CHRONOLOGICAL AGE AT THE TIME OF MEASUREMENT. THE FIVE CLOCKS ENCOMPASS METHYLATION-BASED PREDICTORS OF CHRONOLOGICAL AGE (HORVATHAGE, HANNUMAGE), ALL-CAUSE MORTALITY (DNAM PHENOAGE, DNAM GRIMAGE) AND TELOMERE LENGTH (DNAM TELOMERE LENGTH). A SIXTH EPIGENETIC MEASURE OF AGEING DIFFERS FROM THESE CLOCKS IN THAT IT ACTS AS A SPEEDOMETER PROVIDING A SINGLE TIME-POINT MEASUREMENT OF THE PACE OF AN INDIVIDUAL'S BIOLOGICAL AGEING. THIS MEASURE OF AGEING IS TERMED DUNEDINPOAM. IN THIS STUDY, WE TEST THE ASSOCIATION BETWEEN THESE SIX EPIGENETIC MEASURES OF AGEING AND THE PREVALENCE AND INCIDENCE OF THE LEADING CAUSES OF DISEASE BURDEN AND MORTALITY IN HIGH-INCOME COUNTRIES (N </= 9537, GENERATION SCOTLAND: SCOTTISH FAMILY HEALTH STUDY). RESULTS: DNAM GRIMAGE PREDICTED INCIDENCE OF CLINICALLY DIAGNOSED CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD), TYPE 2 DIABETES AND ISCHEMIC HEART DISEASE AFTER 13 YEARS OF FOLLOW-UP (HAZARD RATIOS = 2.22, 1.52 AND 1.41, RESPECTIVELY). DUNEDINPOAM PREDICTED THE INCIDENCE OF COPD AND LUNG CANCER (HAZARD RATIOS = 2.02 AND 1.45, RESPECTIVELY). DNAM PHENOAGE PREDICTED INCIDENCE OF TYPE 2 DIABETES (HAZARD RATIO = 1.54). DNAM TELOMERE LENGTH ASSOCIATED WITH THE INCIDENCE OF ISCHEMIC HEART DISEASE (HAZARD RATIO = 0.80). DNAM GRIMAGE ASSOCIATED WITH ALL-CAUSE MORTALITY, THE PREVALENCE OF COPD AND SPIROMETRY MEASURES AT THE STUDY BASELINE.

8  5882  52 SYSTEMATIC REVIEW OF LUNG FUNCTION AND COPD WITH PERIPHERAL BLOOD DNA METHYLATION IN POPULATION BASED STUDIES. BACKGROUND: EPIGENETIC VARIATIONS IN PERIPHERAL BLOOD HAVE POTENTIAL AS BIOMARKERS FOR DISEASE. THIS SYSTEMATIC REVIEW ASSESSES THE ASSOCIATION OF LUNG FUNCTION AND CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD) WITH DNA METHYLATION PROFILES IN PERIPHERAL BLOOD FROM POPULATION-BASED STUDIES. METHODS: ONLINE DATABASES MEDLINE, EMBASE, AND WEB OF SCIENCE WERE SEARCHED. GOOGLE SCHOLAR WAS SEARCHED TO IDENTIFY GREY LITERATURE. AFTER REMOVING DUPLICATE ARTICLES, 1155 ARTICLES WERE INDEPENDENTLY SCREENED BY TWO INVESTIGATORS. PEER REVIEWED REPORTS ON POPULATION-BASED STUDIES THAT EXAMINED PERIPHERAL BLOOD DNA METHYLATION IN PARTICIPANTS WITH MEASURED LUNG FUNCTION (FEV1, FEV1/FVC RATIO) OR KNOWN COPD STATUS WERE SELECTED FOR FULL-TEXT REVIEW. SIX ARTICLES WERE SUITABLE FOR INCLUSION. INFORMATION REGARDING STUDY CHARACTERISTICS, DESIGNS, METHODOLOGIES AND CONCLUSIONS WAS EXTRACTED. A NARRATIVE SYNTHESIS WAS PERFORMED BASED ON PUBLISHED RESULTS. RESULTS: THREE OF THE SIX ARTICLES ASSESSED THE ASSOCIATION OF COPD WITH DNA METHYLATION, AND TWO OF THESE ALSO INCLUDED ASSOCIATIONS WITH LUNG FUNCTION. OVERALL, FIVE REPORTS EXAMINED THE ASSOCIATION OF LUNG FUNCTION WITH DNA METHYLATION PROFILES. FIVE OF THE SIX ARTICLES REPORTED 'SIGNIFICANT' RESULTS. HOWEVER, NO CONSISTENT CPG SITES WERE IDENTIFIED ACROSS STUDIES FOR COPD STATUS OR LUNG FUNCTION VALUES. CONCLUSIONS: DNA METHYLATION PATTERNS IN PERIPHERAL BLOOD FROM INDIVIDUALS WITH REDUCED LUNG FUNCTION OR COPD MAY BE DIFFERENT TO THOSE IN PEOPLE WITH NORMAL LUNG FUNCTION. HOWEVER, THIS SYSTEMATIC REVIEW DID NOT FIND ANY CONSISTENT ASSOCIATIONS OF LUNG FUNCTION OR COPD WITH DIFFERENTIALLY METHYLATED CPG SITES. LARGE STUDIES WITH A LONGITUDINAL DESIGN TO ADDRESS REVERSE CAUSALITY MAY PROVE A MORE FRUITFUL AREA OF RESEARCH.

9  4522  35 MULTIDIMENSIONAL EVALUATION OF THE PAIN PROFILE AS PROGNOSTIC FACTOR IN INDIVIDUALS WITH HIP OR KNEE OSTEOARTHRITIS RECEIVING TOTAL JOINT REPLACEMENT: PROTOCOL OF A 2-YEAR LONGITUDINAL PROGNOSTIC COHORT STUDY. INTRODUCTION: KNEE AND HIP OSTEOARTHRITIS ARE TWO HIGHLY PREVALENT MUSCULOSKELETAL PAIN CONDITIONS. UNSUCCESSFUL RATES AFTER HIP/KNEE REPLACEMENT RANGE FROM 10% TO 20%. SUBJECTS WITH SENSITISATION MANIFESTATIONS ARE VULNERABLE TO WORSE CLINICAL OUTCOMES. MOST STUDIES HAVE ANALYSED OUTCOMES UP TO 1 YEAR AFTER SURGERY. THE AIM OF THIS 2-YEAR LONGITUDINAL STUDY WILL BE TO EVALUATE SENSORY-RELATED, PSYCHOLOGICAL AND PSYCHOPHYSICAL PAIN SENSITISATION MANIFESTATIONS AND A POTENTIAL EPIGENETIC BIOMARKER AS PROGNOSTIC CLINICAL OUTCOMES FOR THE DEVELOPMENT OF CHRONIC POSTOPERATIVE PAIN AFTER KNEE OR HIP REPLACEMENT. METHODS AND ANALYSIS: A PROSPECTIVE LONGITUDINAL STUDY WITH A 2-YEAR FOLLOW-UP PERIOD WILL BE CONDUCTED. THE PROGNOSTIC VARIABLES WILL INCLUDE PAIN, FUNCTION, RELATED-DISABILITY, ANXIETY, DEPRESSION, QUALITY OF LIFE, SENSITISATION-ASSOCIATED SYMPTOMS, KINESIOPHOBIA, NEUROPATHIC PAIN AND CATASTROPHISING, AND EXPECTATIVE OF THE INTERVENTION WILL BE ASSESSED BEFORE SURGERY. WE WILL ALSO EVALUATE THE PRESENCE OF THE VAL158MET POLYMORPHISM AS A POSSIBLE EPIGENETIC MARKER. CLINICAL OUTCOMES INCLUDING PAIN, RELATED-DISABILITY AND SELF-PERCEIVED SATISFACTION, SENSITISATION-ASSOCIATED SYMPTOMS AND NEUROPATHIC PAIN WILL BE ASSESSED 3, 6, 12, 18 AND 24 MONTHS AFTER SURGERY. THESE VARIABLES WILL BE USED TO CONSTRUCT THREE PREDICTION MODELS: (1) PAIN AND FUNCTION, (2) SENSITISATION-ASSOCIATED SYMPTOMATOLOGY AND (3) NEUROPATHIC PAIN FEATURES CLASSIFYING THOSE PATIENTS IN RESPONDERS AND NON-RESPONDERS. DATA FROM KNEE OR HIP OSTEOARTHRITIS WILL BE ANALYSED SEPARATELY. STATISTICAL ANALYSES WILL BE CONDUCTED WITH LOGISTIC REGRESSIONS. ETHICS AND DISSEMINATION: THE STUDY HAS BEEN APPROVED BY THE ETHICS COMMITTEE OF BOTH INSTITUTIONS INVOLVED (HOSPITAL UNIVERSITARIO FUNDACION ALCORCON (HUFA) 19-141 AND UNIVERSIDAD REY JUAN CARLOS (URJC) 0312201917319). PARTICIPANTS WILL SIGN THE WRITTEN INFORMED CONSENT BEFORE THEIR INCLUSION. STUDY RESULTS WILL BE DISSEMINATED THROUGH PEER-REVIEWED PUBLICATIONS AND PRESENTATIONS AT SCIENTIFIC MEETINGS.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
10  1960  43 EPIGENETIC AGING IN CHILDREN FROM A SMALL-SCALE FARMING SOCIETY IN THE CONGO BASIN: ASSOCIATIONS WITH CHILD GROWTH AND FAMILY CONFLICT. DEVELOPMENTAL ENVIRONMENTS INFLUENCE INDIVIDUALS' LONG-TERM HEALTH TRAJECTORIES, AND THERE IS INCREASING EMPHASIS ON UNDERSTANDING THE BIOLOGICAL PATHWAYS THROUGH WHICH THIS OCCURS. EPIGENETIC AGING EVALUATES DNA METHYLATION AT A SUITE OF DISTINCT CPG SITES IN THE GENOME, AND EPIGENETIC AGE ACCELERATION (EAA) IS LINKED TO HEIGHTENED CHRONIC MORBIDITY AND MORTALITY RISKS IN ADULTS. CONSEQUENTLY, EAA PROVIDES INSIGHTS ON TRAJECTORIES OF BIOLOGICAL AGING, WHICH EARLY LIFE EXPERIENCES MAY HELP SHAPE. HOWEVER, FEW STUDIES HAVE MEASURED CORRELATES OF CHILDREN'S EPIGENETIC AGING, ESPECIALLY OUTSIDE OF THE U.S. AND EUROPE. IN PARTICULAR, LITTLE IS KNOWN ABOUT HOW CHILDREN'S GROWTH AND DEVELOPMENT RELATE TO EAA IN ECOLOGIES IN WHICH ENERGETIC AND PATHOGENIC STRESSORS ARE COMMONPLACE. WE STUDIED EAA FROM DRIED BLOOD SPOTS AMONG BONDONGO CHILDREN (N = 54) RESIDING IN A SMALL-SCALE, FISHER-FARMER SOCIETY IN A REMOTE REGION OF THE REPUBLIC OF THE CONGO. HERE, INFECTIOUS DISEASE BURDENS AND THEIR RESULTANT ENERGY DEMANDS ARE HIGH. CHILDREN WHO WERE HEAVIER FOR HEIGHT OR TALLER FOR AGE, RESPECTIVELY, EXHIBITED GREATER EAA, INCLUDING INTRINSIC EAA, WHICH IS CONSIDERED TO MEASURE EAA INTERNAL TO CELLS. FURTHERMORE, WE FOUND THAT CHILDREN IN FAMILIES WITH MORE CONFLICT BETWEEN PARENTS HAD GREATER INTRINSIC EAA. THESE RESULTS SUGGEST THAT IN CONTEXTS IN WHICH LIMITED ENERGY MUST BE ALLOCATED TO COMPETING DEMANDS, MORE INVESTMENT IN GROWTH MAY COINCIDE WITH GREATER EAA, WHICH PARALLELS FINDINGS IN EUROPEAN CHILDREN WHO DO NOT FACE SIMILAR ENERGETIC CONSTRAINTS. OUR FINDINGS ALSO INDICATE THAT ASSOCIATIONS BETWEEN ADVERSE FAMILY ENVIRONMENTS AND GREATER INTRINSIC EAA WERE NONETHELESS OBSERVABLE BUT ONLY AFTER ADJUSTMENT FOR COVARIATES RELEVANT TO THE ENERGETICALLY AND IMMUNOLOGICALLY DEMANDING NATURE OF THE LOCAL ECOLOGY.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
11  2605  33 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  1058  38 CLINICAL MEASURES OF ALLOSTATIC LOAD IN CHILDREN AND ADOLESCENTS WITH FOOD ALLERGY, DEPRESSION, OR ANXIETY. PURPOSE: SUSTAINED HIGH STRESS EXPOSURE RESULTS IN CHRONIC ACTIVATION OF THE STRESS RESPONSE SYSTEM, DYSREGULATED STRESS RESPONSES, HIGH ALLOSTATIC LOAD, AND POOR LATER-LIFE HEALTH. CHILDREN AND ADOLESCENTS WITH CHRONIC HEALTH CONDITIONS FACE STRESSORS RELATED TO THEIR CONDITION IN ADDITION TO THOSE TYPICAL OF CHILDHOOD AND ADOLESCENCE, PLACING THEM AT RISK OF HIGH ALLOSTATIC LOAD. THE PURPOSE OF THIS SECONDARY ANALYSIS WAS TO EXAMINE WHETHER YOUTH WITH CHRONIC HEALTH CONDITIONS DIFFER FROM CONTROLS ON CLINICAL MEASURES OF ALLOSTATIC LOAD. DESIGN AND METHODS: A SECONDARY ANALYSIS OF TWO DATASETS, THE ELECTRONIC HEALTH RECORD OF A TERTIARY CHILDREN'S HOSPITAL AND DATA FROM THE SURVEY OF THE HEALTH OF WISCONSIN, COMPARED YOUTH WITH CHRONIC HEALTH CONDITIONS TO CONTROLS ON CLINICAL MEASURES OF ALLOSTATIC LOAD. ADDITIONAL ANALYSES EXPLORED WHETHER PARENTAL STRESS AND MENTAL HEALTH INFLUENCED THESE RELATIONSHIPS. RESULTS: ANALYSES IDENTIFIED DIFFERENCES IN BMI, BLOOD PRESSURE, AND WAIST CIRCUMFERENCE BETWEEN YOUTH WITH FOOD ALLERGY, ANXIETY, OR DEPRESSION, AND CONTROLS. THESE RELATIONSHIPS DIFFERED FOR MALES AND FEMALES AND FOR THOSE WITH COMORBID MENTAL AND PHYSICAL CONDITIONS, AND WERE INFLUENCED BY PARENT STRESS AND MENTAL HEALTH. CONCLUSIONS: RESULTS SUPPORT FUTURE STUDIES EXPLORING WHETHER HIGH STRESS IN YOUTH WITH CHRONIC HEALTH CONDITIONS LEADS TO INCREASED ALLOSTATIC LOAD. INCORPORATING BIOMARKERS AS WELL AS GENETIC AND EPIGENETIC FACTORS WILL PROVIDE CRITICAL INSIGHTS. PRACTICE IMPLICATIONS: YOUTH WITH MENTAL AND PHYSICAL CHCS MAY BE AT INCREASED RISK OF HIGH ALLOSTATIC LOAD, REFLECTED IN CLINICAL MEASURES OF METABOLISM, AND SHOULD HAVE REGULAR ASSESSMENTS OF THEIR METABOLIC HEALTH.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
13  1957  40 EPIGENETIC AGE PREDICTORS IN COMMUNITY-DWELLING ADULTS WITH HIGH IMPACT KNEE PAIN. GERONTOLOGICAL RESEARCH REVEALS CONSIDERABLE INTERINDIVIDUAL VARIABILITY IN AGING PHENOTYPES, AND EMERGING EVIDENCE SUGGESTS THAT HIGH IMPACT CHRONIC PAIN MAY BE ASSOCIATED WITH VARIOUS ACCELERATED BIOLOGICAL AGING PROCESSES. IN PARTICULAR, EPIGENETIC AGING IS A ROBUST PREDICTOR OF HEALTH-SPAN AND DISABILITY COMPARED TO CHRONOLOGICAL AGE ALONE. THE CURRENT STUDY AIMED TO DETERMINE WHETHER SEVERAL EPIGENETIC AGING BIOMARKERS WERE ASSOCIATED WITH HIGH IMPACT CHRONIC PAIN IN MIDDLE TO OLDER AGE ADULTS (44-78 YEARS OLD). PARTICIPANTS (N = 213) UNDERWENT A BLOOD DRAW, DEMOGRAPHIC, PSYCHOSOCIAL, PAIN AND FUNCTIONAL ASSESSMENTS. WE ESTIMATED FIVE EPIGENETIC CLOCKS AND CALCULATED THE DIFFERENCE BETWEEN EPIGENETIC AGE AND CHRONOLOGICAL AGE, WHICH HAS BEEN PREVIOUSLY REPORTED TO PREDICT OVERALL MORTALITY RISK, AS WELL AS INCLUDED ADDITIONAL DERIVED VARIABLES OF EPIGENETIC AGE PREVIOUSLY ASSOCIATED WITH PAIN. THERE WERE SIGNIFICANT DIFFERENCES ACROSS PAIN IMPACT GROUPS IN THREE OUT OF THE FIVE EPIGENETIC CLOCKS EXAMINED (DNAMAGE, DNAMPHENOAGE AND DNAMGRIMAGE), INDICATING THAT PAIN-RELATED DISABILITY DURING THE PAST 6 MONTHS WAS ASSOCIATED WITH MARKERS OF EPIGENETIC AGING. ONLY DNAMPHENOAGE AND DNAMGRIMAGE WERE ASSOCIATED WITH HIGHER KNEE PAIN INTENSITY DURING THE PAST 48 H. FINALLY, PAIN CATASTROPHIZING, DEPRESSIVE SYMPTOMATOLOGY AND MORE NEUROPATHIC PAIN SYMPTOMS WERE SIGNIFICANTLY ASSOCIATED WITH AN OLDER EPIGENOME IN ONLY ONE OF THE FIVE EPIGENETIC CLOCKS (I.E. DNAMGRIMAGE) AFTER CORRECTING FOR MULTIPLE COMPARISONS (CORRECTED P'S < 0.05). GIVEN THE SCANT LITERATURE IN RELATION TO EPIGENETIC AGING AND THE COMPLEX EXPERIENCE OF PAIN, ADDITIONAL RESEARCH IS NEEDED TO UNDERSTAND WHETHER EPIGENETIC AGING MAY HELP IDENTIFY PEOPLE WITH CHRONIC PAIN AT GREATER RISK OF FUNCTIONAL DECLINE AND POORER HEALTH OUTCOMES.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
14  5224  42 PRIORITIZED RESEARCH FOR THE PREVENTION, TREATMENT, AND REVERSAL OF CHRONIC DISEASE: RECOMMENDATIONS FROM THE LIFESTYLE MEDICINE RESEARCH SUMMIT. DECLINING LIFE EXPECTANCY AND INCREASING ALL-CAUSE MORTALITY IN THE UNITED STATES HAVE BEEN ASSOCIATED WITH UNHEALTHY BEHAVIORS, SOCIOECOLOGICAL FACTORS, AND PREVENTABLE DISEASE. A GROWING BODY OF BASIC SCIENCE, CLINICAL RESEARCH, AND POPULATION HEALTH EVIDENCE POINTS TO THE BENEFITS OF HEALTHY BEHAVIORS, ENVIRONMENTS AND POLICIES TO MAINTAIN HEALTH AND PREVENT, TREAT, AND REVERSE THE ROOT CAUSES OF COMMON CHRONIC DISEASES. SIMILARLY, INNOVATIONS IN RESEARCH METHODOLOGIES, STANDARDS OF EVIDENCE, EMERGENCE OF UNIQUE STUDY COHORTS, AND BREAKTHROUGHS IN DATA ANALYTICS AND MODELING CREATE NEW POSSIBILITIES FOR PRODUCING BIOMEDICAL KNOWLEDGE AND CLINICAL TRANSLATION. TO UNDERSTAND THESE ADVANCES AND INFORM FUTURE DIRECTIONS RESEARCH, THE LIFESTYLE MEDICINE RESEARCH SUMMIT WAS CONVENED AT THE UNIVERSITY OF PITTSBURGH ON DECEMBER 4-5, 2019. THE SUMMIT'S GOAL WAS TO REVIEW CURRENT STATUS AND DEFINE RESEARCH PRIORITIES IN THE SIX CORE AREAS OF LIFESTYLE MEDICINE: PLANT-PREDOMINANT NUTRITION, PHYSICAL ACTIVITY, SLEEP, STRESS, ADDICTIVE BEHAVIORS, AND POSITIVE PSYCHOLOGY/SOCIAL CONNECTION. FORTY INVITED SUBJECT MATTER EXPERTS (1) REVIEWED EXISTING KNOWLEDGE AND GAPS RELATING LIFESTYLE BEHAVIORS TO COMMON CHRONIC DISEASES, SUCH AS CARDIOVASCULAR DISEASE, DIABETES, MANY CANCERS, INFLAMMATORY- AND IMMUNE-RELATED DISORDERS AND OTHER CONDITIONS; AND (2) DISCUSSED THE POTENTIAL FOR APPLYING CUTTING-EDGE MOLECULAR, CELLULAR, EPIGENETIC AND EMERGING SCIENCE KNOWLEDGE AND COMPUTATIONAL METHODOLOGIES, RESEARCH DESIGNS, AND STUDY COHORTS TO ACCELERATE CLINICAL APPLICATIONS ACROSS ALL SIX DOMAINS OF LIFESTYLE MEDICINE. NOTABLY, FEDERAL HEALTH AGENCIES, SUCH AS THE DEPARTMENT OF DEFENSE AND VETERANS ADMINISTRATION HAVE BEGUN TO ADOPT "WHOLE-PERSON HEALTH AND PERFORMANCE" MODELS THAT ADDRESS THESE LIFESTYLE AND ENVIRONMENTAL ROOT CAUSES OF CHRONIC DISEASE AND ASSOCIATED MORBIDITY, MORTALITY, AND COST. RECOMMENDATIONS STRONGLY SUPPORT LEVERAGING EMERGING RESEARCH METHODOLOGIES, SYSTEMS BIOLOGY, AND COMPUTATIONAL MODELING IN ORDER TO ACCELERATE EFFECTIVE CLINICAL AND POPULATION SOLUTIONS TO IMPROVE HEALTH AND REDUCE SOCIETAL COSTS. NEW AND ALTERNATIVE HIERARCHIES OF EVIDENCE ARE ALSO BE NEEDED IN ORDER TO ASSESS THE QUALITY OF EVIDENCE AND DEVELOP EVIDENCE-BASED GUIDELINES ON LIFESTYLE MEDICINE. CHILDREN AND UNDERSERVED POPULATIONS WERE IDENTIFIED AS PRIORITIZED GROUPS TO STUDY. THE COVID-19 PANDEMIC, WHICH DISPROPORTIONATELY IMPACTS PEOPLE WITH CHRONIC DISEASES THAT ARE AMENABLE TO EFFECTIVE LIFESTYLE MEDICINE INTERVENTIONS, MAKES THE SUMMIT'S FINDINGS AND RECOMMENDATIONS FOR FUTURE RESEARCH PARTICULARLY TIMELY AND RELEVANT.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
15  5846  39 STUDY PROTOCOL: RATIONALE AND DESIGN OF THE COMMUNITY-BASED PROSPECTIVE COHORT STUDY OF KIDNEY FUNCTION AND DIABETES IN RURAL NEW MEXICO, THE COMPASS STUDY. BACKGROUND: RURAL AREAS IN THE STATE OF NEW MEXICO HAVE BEEN THE "GROUND-ZERO" FOR THE EPIDEMIC OF DIABETIC CHRONIC KIDNEY DISEASE (CKD) IN THE UNITED STATES. HOWEVER, THERE IS LIMITED RESEARCH ABOUT RISK FACTORS OF DIABETIC CKD IN THIS AREA AND SCARCE DATA REGARDING THE PERFORMANCE OF EMERGING MARKERS OF RENAL FILTRATION AND EPIGENETIC BIOMARKERS OF RENAL FUNCTION AND DIABETES IN THIS AREA WITH ITS UNIQUE ETHNIC/RACIAL POPULATION. WE DESIGNED THE COMPASS STUDY AS A COMMUNITY-BASED PROGRAM IN RURAL NEW MEXICO AIMING TO SCREEN FOR CKD AND TO DISCOVER CKD-RELATED TRANSLATIONAL BIOMARKERS. METHODS/DESIGN: THE STUDY INVOLVES A PROSPECTIVE, LONGITUDINAL COHORT DESIGN INVOLVING INDIVIDUALS LIVING IN RURAL NEW MEXICO. PARTICIPANTS UNDERGO A SCREENING FOR KIDNEY DISEASE USING MARKERS OF ABNORMAL RENAL FILTRATION (IMPAIRED GLOMERULAR FILTRATION RATE) OR DAMAGE (ALBUMINURIA). THOSE FOUND TO HAVE CKD ON THE BASIS OF THESE TESTS OR THOSE AT RISK FOR CKD ARE ENROLLED IN A PROSPECTIVE LONGITUDINAL COHORT. WE MEASURE MARKERS OF RENAL FUNCTION, INSULIN RESISTANCE AND EPIGENETICS (MICRORNAS) ON PATIENTS. INDIVIDUALS ARE INVITED TO PARTICIPATE IN INTERVIEWS AND FOCUS GROUPS IN ORDER TO CHARACTERIZE THEIR ATTITUDES TOWARDS RESEARCH AND BARRIERS OR FACILITATORS TO PARTICIPATION IN FUTURE RESEARCH STUDIES ABOUT KIDNEY DISEASE. DISCUSSION: THIS STUDY WILL PROVIDE IMPORTANT DATA ABOUT THE LOCAL EPIDEMIOLOGY OF KIDNEY DISEASE IN A HIGH-RISK RURAL SETTING AND THE UTILITY OF EMERGING RENAL FILTRATION MARKERS (BETA 2 MICROGLOBULIN AND CYSTATIN C), WHILE GENERATING DATA AND METHODS FOR THE ANALYSES OF MICRORNA BIOMARKERS. THE QUALITATIVE RESEARCH SUBPROJECT WILL IDENTIFY FACTORS ASSOCIATED WITH INCREASED WILLINGNESS TO PARTICIPATE IN FUTURE TRANSLATIONAL RESEARCH PROJECTS. WITH ITS GEOGRAPHICAL FOCUS, THIS STUDY WILL ADDRESS A CRITICAL DISPARITY IN KIDNEY DISEASE RESEARCH, WHILE GENERATING NOVEL EPIGENETIC DATA THAT ARE RELEVANT FOR FUTURE STUDIES IN THE GENERAL POPULATION.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
16  2411  33 EPIGENETIC SCORES FOR THE CIRCULATING PROTEOME AS TOOLS FOR DISEASE PREDICTION. PROTEIN BIOMARKERS HAVE BEEN IDENTIFIED ACROSS MANY AGE-RELATED MORBIDITIES. HOWEVER, CHARACTERISING EPIGENETIC INFLUENCES COULD FURTHER INFORM DISEASE PREDICTIONS. HERE, WE LEVERAGE EPIGENOME-WIDE DATA TO STUDY LINKS BETWEEN THE DNA METHYLATION (DNAM) SIGNATURES OF THE CIRCULATING PROTEOME AND INCIDENT DISEASES. USING DATA FROM FOUR COHORTS, WE TRAINED AND TESTED EPIGENETIC SCORES (EPISCORES) FOR 953 PLASMA PROTEINS, IDENTIFYING 109 SCORES THAT EXPLAINED BETWEEN 1% AND 58% OF THE VARIANCE IN PROTEIN LEVELS AFTER ADJUSTING FOR KNOWN PROTEIN QUANTITATIVE TRAIT LOCI (PQTL) GENETIC EFFECTS. BY PROJECTING THESE EPISCORES INTO AN INDEPENDENT SAMPLE (GENERATION SCOTLAND; N = 9537) AND RELATING THEM TO INCIDENT MORBIDITIES OVER A FOLLOW-UP OF 14 YEARS, WE UNCOVERED 137 EPISCORE-DISEASE ASSOCIATIONS. THESE ASSOCIATIONS WERE LARGELY INDEPENDENT OF IMMUNE CELL PROPORTIONS, COMMON LIFESTYLE AND HEALTH FACTORS, AND BIOLOGICAL AGING. NOTABLY, WE FOUND THAT OUR DIABETES-ASSOCIATED EPISCORES HIGHLIGHTED PREVIOUS TOP BIOMARKER ASSOCIATIONS FROM PROTEOME-WIDE ASSESSMENTS OF DIABETES. THESE EPISCORES FOR PROTEIN LEVELS CAN THEREFORE BE A VALUABLE RESOURCE FOR DISEASE PREDICTION AND RISK STRATIFICATION.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
17  1151  48 CONNECTIONS AMONG BIOLOGIC EMBEDDING OF CHILDHOOD ADVERSITY, ADULT CHRONIC ILLNESS, AND WOUND CARE: A REVIEW OF THE LITERATURE. ADVERSE CHILDHOOD EXPERIENCES (ACES) BIOLOGICALLY EMBED BY ALTERING BRAIN DEVELOPMENT AND INFLUENCING EPIGENETIC MECHANISMS. THESE EXPERIENCES MAY GENERATE HEALTH RISK FACTORS. PURPOSE: A LITERATURE REVIEW WAS CONDUCTED TO COMPARE ACE-GENERATED HEALTH RISK FACTORS WITH RISK FACTORS FOR WOUND DEVELOPMENT AND ABERRANT HEALING, AS WELL AS TO IDENTIFY A GAP IN LITERATURE REGARDING CRITICAL CONNECTIONS BETWEEN ACES, CHRONIC ILLNESS, AND WOUND DEVELOPMENT/HEALING, WITH ASSOCIATED PRACTICE IMPLICATIONS. METHODOLOGY: A LITERATURE SEARCH OF ENGLISH-LANGUAGE ARTICLES WAS CONDUCTED USING THE CUMULATIVE INDEX OF NURSING AND ALLIED HEALTH LITERATURE, MEDLINE, AND PUBMED USING THE SEARCH TERMS ADVERSE CHILDHOOD EXPERIENCES, ADULTS, WOUNDS, CHRONIC DISEASE OR ILLNESS, AND EPIGENETICS. THE SEARCHES YIELDED 561 PUBLICATIONS REGARDING ACES, CHRONIC ILLNESS OR DISEASE, AND ADULT; 182 FOR ACES; AND 547 FOR EPIGENETICS AND WOUNDS. ABSTRACTS WERE REVIEWED TO REMOVE DUPLICATES AND STUDIES WITH PARTICIPANTS WHO WERE <18 YEARS OLD. PUBLICATIONS WERE REVIEWED FOR SALIENCE; THOSE DISCUSSING THE BIOLOGIC PLAUSIBILITY OF ACES CONTRIBUTING TO ADULT ILLNESSES AND ASSOCIATED WOUND DEVELOPMENT AND HEALING WERE REVIEWED FOR INCLUSION. RESULTS: SIXTY-EIGHT (68) PUBLICATIONS WERE FOUND APPROPRIATE FOR REVIEW AND INCLUDED POPULATION-BASED STUDIES; LITERATURE REVIEWS; EPIDEMIOLOGIC DATA; META-ANALYSES; AND SYSTEMATIC, CROSS-SECTIONAL, OBSERVATIONAL, AND PROSPECTIVE STUDIES AS SINGULAR OR MIXED METHODS DESIGNS. A SUBSTANTIAL OVERLAP WAS FOUND IN TERMS OF RISK FACTORS GENERATED BY ACE EXPOSURE AND RISK FACTORS FOR WOUND DEVELOPMENT/HEALING, AS WAS A GAP IN THE LITERATURE REGARDING THIS RELATIONSHIP. EPIGENETIC MECHANISMS AND ALTERED BRAIN DEVELOPMENT ARE IMPLICATED IN PROCESSES THROUGH WHICH CHILDHOOD ADVERSITY ERODES HUMAN HEALTH. CONCLUSION: ADULT HEALTH RISKS AS A RESULT OF EXPOSURE TO ACES AND CRITICAL CONNECTIONS WITH RISKS FOR WOUND DEVELOPMENT AND DISRUPTED WOUND HEALING VIA EPIGENETIC INFLUENCES ARE RECOGNIZED IN THE LITERATURE. PRACTICE IMPLICATIONS INCLUDE CONSIDERING SCREENING FOR THE RISK FACTOR OF ACES EXPOSURE IN ADULT PATIENTS TO IDENTIFY THIS ADDITIONAL RISK FACTOR AND PRACTICING PATIENT-CENTERED, TRAUMA-INFORMED CARE. FURTHER RESEARCH INTO THE INTEGRATIVE ROLES OF THESE FACTORS IS WARRANTED.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
18   178  39 ACCELERATED EPIGENETIC AGING AS A RISK FACTOR FOR CHRONIC OBSTRUCTIVE PULMONARY DISEASE AND DECREASED LUNG FUNCTION IN TWO PROSPECTIVE COHORT STUDIES. CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD) IS A FREQUENT DIAGNOSIS IN OLDER INDIVIDUALS AND CONTRIBUTOR TO GLOBAL MORBIDITY AND MORTALITY. GIVEN THE LINK BETWEEN LUNG DISEASE AND AGING, WE NEED TO UNDERSTAND HOW MOLECULAR INDICATORS OF AGING RELATE TO LUNG FUNCTION AND DISEASE. USING DATA FROM THE POPULATION-BASED KORA (COOPERATIVE HEALTH RESEARCH IN THE REGION OF AUGSBURG) SURVEYS, WE ASSOCIATED BASELINE EPIGENETIC (DNA METHYLATION) AGE ACCELERATION WITH INCIDENT COPD AND LUNG FUNCTION. MODELS WERE ADJUSTED FOR AGE, SEX, SMOKING, HEIGHT, WEIGHT, AND BASELINE LUNG DISEASE AS APPROPRIATE. ASSOCIATIONS WERE REPLICATED IN THE NORMATIVE AGING STUDY. OF 770 KORA PARTICIPANTS, 131 DEVELOPED INCIDENT COPD OVER 7 YEARS. BASELINE ACCELERATED EPIGENETIC AGING WAS SIGNIFICANTLY ASSOCIATED WITH INCIDENT COPD. THE CHANGE IN AGE ACCELERATION (FOLLOW-UP - BASELINE) WAS MORE STRONGLY ASSOCIATED WITH COPD THAN BASELINE AGING ALONE. THE ASSOCIATION BETWEEN THE CHANGE IN AGE ACCELERATION BETWEEN BASELINE AND FOLLOW-UP AND INCIDENT COPD REPLICATED IN THE NORMATIVE AGING STUDY. ASSOCIATIONS WITH SPIROMETRIC LUNG FUNCTION PARAMETERS WERE WEAKER THAN THOSE WITH COPD, BUT A META-ANALYSIS OF BOTH COHORTS PROVIDE SUGGESTIVE EVIDENCE OF ASSOCIATIONS. ACCELERATED EPIGENETIC AGING, BOTH BASELINE MEASURES AND CHANGES OVER TIME, MAY BE A RISK FACTOR FOR COPD AND REDUCED LUNG FUNCTION.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
19   667  63 BLOOD-BASED EPIGENOME-WIDE ANALYSES OF 19 COMMON DISEASE STATES: A LONGITUDINAL, POPULATION-BASED LINKED COHORT STUDY OF 18,413 SCOTTISH INDIVIDUALS. BACKGROUND: DNA METHYLATION IS A DYNAMIC EPIGENETIC MECHANISM THAT OCCURS AT CYTOSINE-PHOSPHATE-GUANINE DINUCLEOTIDE (CPG) SITES. EPIGENOME-WIDE ASSOCIATION STUDIES (EWAS) INVESTIGATE THE STRENGTH OF ASSOCIATION BETWEEN METHYLATION AT INDIVIDUAL CPG SITES AND HEALTH OUTCOMES. ALTHOUGH BLOOD METHYLATION MAY ACT AS A PERIPHERAL MARKER OF COMMON DISEASE STATES, PREVIOUS EWAS HAVE TYPICALLY FOCUSED ONLY ON INDIVIDUAL CONDITIONS AND HAVE HAD LIMITED POWER TO DISCOVER DISEASE-ASSOCIATED LOCI. THIS STUDY EXAMINED THE ASSOCIATION OF BLOOD DNA METHYLATION WITH THE PREVALENCE OF 14 DISEASE STATES AND THE INCIDENCE OF 19 DISEASE STATES IN A SINGLE POPULATION OF OVER 18,000 SCOTTISH INDIVIDUALS. METHODS AND FINDINGS: DNA METHYLATION WAS ASSAYED AT 752,722 CPG SITES IN WHOLE-BLOOD SAMPLES FROM 18,413 VOLUNTEERS IN THE FAMILY-STRUCTURED, POPULATION-BASED COHORT STUDY GENERATION SCOTLAND (AGE RANGE 18 TO 99 YEARS). EWAS TESTED FOR CROSS-SECTIONAL ASSOCIATIONS BETWEEN BASELINE CPG METHYLATION AND 14 PREVALENT DISEASE STATES, AND FOR LONGITUDINAL ASSOCIATIONS BETWEEN BASELINE CPG METHYLATION AND 19 INCIDENT DISEASE STATES. PREVALENT CASES WERE SELF-REPORTED ON HEALTH QUESTIONNAIRES AT THE BASELINE. INCIDENT CASES WERE IDENTIFIED USING LINKAGE TO SCOTTISH PRIMARY (READ 2) AND SECONDARY (ICD-10) CARE RECORDS, AND THE CENSORING DATE WAS SET TO OCTOBER 2020. THE MEAN TIME-TO-DIAGNOSIS RANGED FROM 5.0 YEARS (FOR CHRONIC PAIN) TO 11.7 YEARS (FOR CORONAVIRUS DISEASE 2019 (COVID-19) HOSPITALISATION). THE 19 DISEASE STATES CONSIDERED IN THIS STUDY WERE SELECTED IF THEY WERE PRESENT ON THE WORLD HEALTH ORGANISATION'S 10 LEADING CAUSES OF DEATH AND DISEASE BURDEN OR INCLUDED IN BASELINE SELF-REPORT QUESTIONNAIRES. EWAS MODELS WERE ADJUSTED FOR AGE AT METHYLATION TYPING, SEX, ESTIMATED WHITE BLOOD CELL COMPOSITION, POPULATION STRUCTURE, AND 5 COMMON LIFESTYLE RISK FACTORS. A STRUCTURED LITERATURE REVIEW WAS ALSO CONDUCTED TO IDENTIFY EXISTING EWAS FOR ALL 19 DISEASE STATES TESTED. THE MEDLINE, EMBASE, WEB OF SCIENCE, AND PREPRINT SERVERS WERE SEARCHED TO RETRIEVE RELEVANT ARTICLES INDEXED AS OF MARCH 27, 2023. FIFTY-FOUR OF APPROXIMATELY 2,000 INDEXED ARTICLES MET OUR INCLUSION CRITERIA: ASSAYED BLOOD-BASED DNA METHYLATION, HAD >20 INDIVIDUALS IN EACH COMPARISON GROUP, AND EXAMINED ONE OF THE 19 CONDITIONS CONSIDERED. FIRST, WE ASSESSED WHETHER THE ASSOCIATIONS IDENTIFIED IN OUR STUDY WERE REPORTED IN PREVIOUS STUDIES. WE IDENTIFIED 69 ASSOCIATIONS BETWEEN CPGS AND THE PREVALENCE OF 4 CONDITIONS, OF WHICH 58 WERE NEWLY DESCRIBED. THE CONDITIONS WERE BREAST CANCER, CHRONIC KIDNEY DISEASE, ISCHEMIC HEART DISEASE, AND TYPE 2 DIABETES MELLITUS. WE ALSO UNCOVERED 64 CPGS THAT ASSOCIATED WITH THE INCIDENCE OF 2 DISEASE STATES (COPD AND TYPE 2 DIABETES), OF WHICH 56 WERE NOT REPORTED IN THE SURVEYED LITERATURE. SECOND, WE ASSESSED REPLICATION ACROSS EXISTING STUDIES, WHICH WAS DEFINED AS THE REPORTING OF AT LEAST 1 COMMON SITE IN >2 STUDIES THAT EXAMINED THE SAME CONDITION. ONLY 6/19 DISEASE STATES HAD EVIDENCE OF SUCH REPLICATION. THE LIMITATIONS OF THIS STUDY INCLUDE THE NONCONSIDERATION OF MEDICATION DATA AND A POTENTIAL LACK OF GENERALIZABILITY TO INDIVIDUALS THAT ARE NOT OF SCOTTISH AND EUROPEAN ANCESTRY. CONCLUSIONS: WE DISCOVERED OVER 100 ASSOCIATIONS BETWEEN BLOOD METHYLATION SITES AND COMMON DISEASE STATES, INDEPENDENTLY OF MAJOR CONFOUNDING RISK FACTORS, AND A NEED FOR GREATER STANDARDISATION AMONG EWAS ON HUMAN DISEASE.	2023	

20  4922  40 PARENTAL AGE AND RISK OF LYMPHOID NEOPLASMS. HIGH PARENTAL AGE AT CHILDBIRTH HAS REPEATEDLY BEEN LINKED TO CHILDHOOD MALIGNANCIES, WHILE FEW STUDIES HAVE FOCUSED ON THE OFFSPRING'S RISK OF ADULT CANCER. IN THIS POPULATION-BASED CASE-CONTROL STUDY, WE IDENTIFIED 32,000 PATIENTS WITH LYMPHOID NEOPLASMS, DIAGNOSED AT AGES 0-79 YEARS DURING THE PERIOD 1987-2011, AND 160,000 MATCHED CONTROLS IN SWEDEN. USING PROSPECTIVELY REGISTERED DATA ON THEIR FIRST-DEGREE RELATIVES, WE EVALUATED THE IMPACT OF PARENTAL AGE ON THE RISK OF LYMPHOID NEOPLASMS BY SUBTYPE. OVERALL, EACH 5-YEAR INCREMENT IN MATERNAL AGE WAS ASSOCIATED WITH A 3% INCREASE IN INCIDENCE OF OFFSPRING LYMPHOID NEOPLASMS (HAZARD RATIO = 1.03, 95% CONFIDENCE INTERVAL: 1.02, 1.04). THE ASSOCIATION WAS SIMILAR FOR PATERNAL AGE AND PRESENT EVEN AMONG INDIVIDUALS OLDER THAN 70 YEARS OF AGE AT DIAGNOSIS. STRATIFIED ANALYSES FURTHER REVEALED THAT THE ASSOCIATION WAS LIMITED TO CERTAIN SUBTYPES, MOSTLY OF INDOLENT NATURE. RISKS OF CHRONIC LYMPHOCYTIC LEUKEMIA, FOLLICULAR LYMPHOMA, AND MANTLE CELL LYMPHOMA WERE 5%-10% HIGHER PER 5-YEAR INCREMENT IN MATERNAL AGE, BUT NO ASSOCIATIONS WERE OBSERVED FOR ACUTE LYMPHOBLASTIC LEUKEMIA, PLASMA CELL NEOPLASMS, OR DIFFUSE LARGE B-CELL LYMPHOMA. THESE FINDINGS INDICATED THAT PRENATAL GENETIC OR EPIGENETIC CHANGES INFLUENCE RISK OF ADULT LYMPHOID NEOPLASMS AND SUGGEST A DIFFERENCE IN THIS ASSOCIATION BETWEEN AGGRESSIVE AND INDOLENT LYMPHOMA SUBTYPES.	2017
