1  2016 178 EPIGENETIC BIOMARKERS IN PROGRESSION FROM NON-DYSPLASTIC BARRETT'S OESOPHAGUS TO OESOPHAGEAL ADENOCARCINOMA: A SYSTEMATIC REVIEW PROTOCOL. INTRODUCTION: BARRETT'S OESOPHAGUS (BO), A METAPLASTIC CONDITION AFFECTING THE LOWER OESOPHAGUS DUE TO LONG-STANDING GASTRO-OESOPHAGEAL REFLUX AND CHRONIC INFLAMMATION, IS A PRECURSOR LESION FOR OESOPHAGEAL ADENOCARCINOMA (OADC). THERE IS NO CLINICAL TEST TO PREDICT WHICH PATIENTS WITH BO WILL PROGRESS TO OADC. THE BRITISH SOCIETY OF GASTROENTEROLOGY RECOMMENDS ENDOSCOPIC SURVEILLANCE OF PATIENTS WITH BO. EPIGENETIC CHANGES HAVE BEEN WELL CHARACTERISED IN THE NEOPLASTIC PROGRESSION OF ULCERATIVE COLITIS TO COLONIC CARCINOMA, ANOTHER GASTROINTESTINAL CANCER ASSOCIATED WITH CHRONIC INFLAMMATION. THIS SYSTEMATIC REVIEW PROTOCOL AIMS TO IDENTIFY AND EVALUATE STUDIES WHICH EXAMINE EPIGENETIC BIOMARKERS IN BO AND THEIR ASSOCIATION WITH PROGRESSION TO OADC. METHODS AND ANALYSIS: ALL PROSPECTIVE AND RETROSPECTIVE PRIMARY STUDIES, AND EXISTING SYSTEMATIC REVIEWS INVESTIGATING EPIGENETIC MARKERS INCLUDING DNA METHYLATION, HISTONE MODIFICATION, CHROMATIN REMODELLING, MICRO AND NON-CODING RNAS OF ALL TYPES WILL BE ELIGIBLE FOR INCLUSION. ELIGIBLE PATIENTS ARE THOSE OVER THE AGE OF 18 WITH BO, BO WITH DYSPLASIA, OADC OR UNSPECIFIED OESOPHAGEAL CANCER. A COMPREHENSIVE SEARCH OF BIBLIOGRAPHIC DATABASES USING COMBINATIONS OF TEXT AND INDEX WORDS RELATING TO THE POPULATION, PROGNOSTIC MARKERS AND OUTCOME WILL BE UNDERTAKEN WITH NO LANGUAGE RESTRICTIONS. RESULTS WILL BE SCREENED BY 2 INDEPENDENT REVIEWERS AND DATA EXTRACTED USING A STANDARDISED PROFORMA. THE QUALITY AND RISK OF BIAS OF INDIVIDUAL STUDIES WILL BE ASSESSED USING THE QUALITY IN PROGNOSTIC STUDIES (QUIPS) TOOL. A NARRATIVE SYNTHESIS OF ALL EVIDENCE WILL BE PERFORMED WITH KEY FINDINGS TABULATED. META-ANALYSIS WILL BE CONSIDERED WHERE STUDIES AND REPORTED OUTCOMES ARE CONSIDERED SUFFICIENTLY HOMOGENEOUS, BOTH CLINICALLY AND METHODOLOGICALLY. FINDINGS WILL BE INTERPRETED IN THE CONTEXT OF THE QUALITY OF INCLUDED STUDIES. THE SYSTEMATIC REVIEW WILL BE REPORTED ACCORDING TO PRISMA GUIDELINES. ETHICS AND DISSEMINATION: THIS IS A SYSTEMATIC REVIEW OF COMPLETED STUDIES AND NO ETHICAL APPROVAL IS REQUIRED. FINDINGS FROM THE FULL SYSTEMATIC REVIEW WILL BE SUBMITTED FOR PUBLICATION AND PRESENTATION AT NATIONAL AND INTERNATIONAL CONFERENCES WHICH WILL INFORM FUTURE RESEARCH ON RISK STRATIFICATION IN PATIENTS WITH BO.

2  6112  57 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
3   190  33 ACETYL-L-CARNITINE IN PAINFUL PERIPHERAL NEUROPATHY: A SYSTEMATIC REVIEW. ACETYL-L-CARNITINE (ALC) HAS SHOWN A NEUROPROTECTIVE EFFECT IN PATIENTS WITH PERIPHERAL NEUROPATHIES OF DIFFERENT ETIOLOGIES. PRECLINICAL STUDIES DEMONSTRATED A CENTRAL ANTI-NOCICEPTIVE ACTION, BOTH IN NEUROPATHIC AND NOCICEPTIVE PAIN MODELS. THE PRESENT REVIEW AIMS TO PROVIDE THE KNOWLEDGE ON THE EFFICACY OF ALC IN PATIENTS WITH PAINFUL PERIPHERAL NEUROPATHY, BASED ON THE EVIDENCE. CONSISTENT WITH THE PRISMA STATEMENT, AUTHORS SEARCHED PUBMED, EMBASE AND THE COCHRANE DATABASE OF SYSTEMATIC REVIEWS FOR RELEVANT PAPERS, INCLUDING THOSE ISSUED BEFORE APRIL 2018. TWO AUTHORS INDEPENDENTLY SELECTED STUDIES FOR INCLUSION AND DATA EXTRACTION: ONLY TRIALS INCLUDING PATIENTS WITH A DIAGNOSIS OF PERIPHERAL NEUROPATHY AND INVOLVING AT LEAST 10 PATIENTS WERE CONSIDERED FOR THE PURPOSES OF THIS REVIEW. FOURTEEN CLINICAL TRIALS WERE REVISED, TO PROVIDE THE LEVEL OF EVIDENCE FOR NEUROPATHY. TO ASSESS THE GLOBAL EFFICACY OF ALC IN PAINFUL PERIPHERAL NEUROPATHY, A META-ANALYSIS OF FOUR RANDOMIZED CONTROLLED TRIALS WAS PERFORMED. MEAN DIFFERENCE IN PAIN REDUCTION AS MEASURED ON A 10-CM VAS, AND 95% CIS WERE USED FOR POOLING CONTINUOUS DATA FROM EACH TRIAL. FOUR RANDOMIZED CONTROLLED TRIALS TESTED ALC IN PATIENTS WITH NEUROPATHY SECONDARY TO DIABETES AND TO ANTIRETROVIRAL THERAPY FOR HIV. COMPARED TO PLACEBO, ALC PRODUCED A SIGNIFICANT PAIN REDUCTION EQUAL TO 20.2% (95% CI: 8.3%-32.1%, P<0.0001) WITH RESPECT TO BASELINE. CLINICAL TRIALS ALSO SHOWED BENEFICIAL EFFECTS ON NERVE CONDUCTION PARAMETERS AND NERVE FIBER REGENERATION, WITH A GOOD SAFETY PROFILE. THESE DATA INDICATE THAT ALC PROVIDES AN EFFECTIVE AND SAFE TREATMENT IN PATIENTS WITH PAINFUL PERIPHERAL NEUROPATHY. WE RECOMMEND FURTHER STUDIES TO ASSESS THE OPTIMAL DOSE AND DURATION OF THE THERAPEUTIC EFFECT (ALSO AFTER TREATMENT WITHDRAWAL).	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
4  4865  32 ORO-FACIAL PAIN AND TEMPOROMANDIBULAR DISORDERS CLASSIFICATION SYSTEMS: A CRITICAL APPRAISAL AND FUTURE DIRECTIONS. IT IS A DIFFICULT UNDERTAKING TO DESIGN A CLASSIFICATION SYSTEM FOR ANY DISEASE ENTITY, LET ALONE FOR ORO-FACIAL PAIN (OFP) AND MORE SPECIFICALLY FOR TEMPOROMANDIBULAR DISORDERS (TMD). A FURTHER COMPLICATION OF THIS TASK IS THAT BOTH PHYSICAL AND PSYCHOSOCIAL VARIABLES MUST BE INCLUDED. TO AUGMENT THIS PROCESS, A TWO-STEP SYSTEMATIC REVIEW, ADHERING TO PRISMA GUIDELINES, OF THE CLASSIFICATION SYSTEMS PUBLISHED DURING THE LAST 20 YEARS FOR OFP AND TMD WAS PERFORMED. THE FIRST SEARCH STEP IDENTIFIED 190 POTENTIAL CITATIONS WHICH ULTIMATELY RESULTED IN ONLY 17 ARTICLES BEING INCLUDED FOR IN-DEPTH ANALYSIS AND REVIEW. THE SECOND STEP RESULTED IN ONLY 5 ARTICLES BEING SELECTED FOR INCLUSION IN THIS REVIEW. FIVE ADDITIONAL ARTICLES AND FOUR CLASSIFICATION GUIDELINES/CRITERIA WERE ALSO INCLUDED DUE TO EXPANSION OF THE SEARCH CRITERIA. THUS, IN TOTAL, 14 DOCUMENTS COMPRISING ARTICLES AND GUIDELINES/CRITERIA (8 PROPOSALS OF CLASSIFICATION SYSTEMS FOR OFP; 6 FOR TMD) WERE SELECTED FOR INCLUSION IN THE SYSTEMATIC REVIEW. FOR EACH, A DISCUSSION AS TO THEIR ADVANTAGES, STRENGTHS AND LIMITATIONS WAS PROVIDED. SUGGESTIONS REGARDING THE FUTURE DIRECTION FOR IMPROVING THE CLASSIFICATION PROCESS WITH THE USE OF ONTOLOGICAL PRINCIPLES RATHER THAN TAXONOMY ARE DISCUSSED. FURTHERMORE, THE POTENTIAL FOR EXPANDING THE SCOPE OF AXES INCLUDED IN EXISTING CLASSIFICATION SYSTEMS, TO INCLUDE GENETIC, EPIGENETIC AND NEUROBIOLOGICAL VARIABLES, IS EXPLORED. IT IS THEREFORE RECOMMENDED THAT FUTURE CLASSIFICATION SYSTEM PROPOSALS BE BASED ON COMBINED APPROACHES AIMING TO PROVIDE ARCHETYPAL TREATMENT-ORIENTED CLASSIFICATIONS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
5   455  48 APPLICATIONS OF YOGA IN ORAL ONCOLOGY: A SYSTEMATIC SCOPING REVIEW. BACKGROUND AND AIMS: YOGA IS WELL-THOUGHT-OUT AS AN ALL-INCLUSIVE APPROACH GLOBALLY AND CAN BE ADMINISTERED IN CLINICAL CARE AS AN INTEGRATIVE OR ALTERNATE APPROACH TO REGULAR TREATMENT. YOGA EXERCISE HAS BEEN DISCLOSED TO INFLUENCE REMISSION FROM CANCER CELLS OVER A LONG PERIOD OF TIME AND ALSO REVERSES EPIGENETIC ALTERATIONS. APPLICATIONS OF YOGA IN THE MANAGEMENT OF ORAL ONCOLOGY PATIENTS ARE SCARCE, HENCE THE NEED FOR A SCOPING REVIEW OF THE LITERATURE. HENCE, THIS STUDY AIMED TO CONDUCT A SCOPING REVIEW OF THE EXISTING EMPIRICAL EVIDENCE ON THE APPLICATIONS OF YOGA IN ORAL ONCOLOGY. METHODS: THE REVIEW METHODOLOGY WAS INFORMED BY JOANNA BRIGG'S INSTITUTE GUIDELINES FOR SYSTEMATIC SCOPING REVIEWS, AND THE REVIEW WAS REPORTED IN ACCORDANCE WITH THE PREFERRED REPORTING ITEMS FOR SYSTEMATIC REVIEWS AND META-ANALYSES EXTENSION FOR SCOPING REVIEWS. TEN DATABASES WERE SEARCHED. THE RECORDS OF ALL THE LITERATURE RETRIEVED FROM THE SEARCH WERE IMPORTED INTO THE RAYYAN SOFTWARE FOR DEDUPLICATION. AFTER THE FULL-TEXT SCREENING, ONLY TWO WERE FOUND ELIGIBLE FOR INCLUSION IN THE SCOPING REVIEW. DATA OBTAINED IN THE INCLUDED LITERATURE WERE EXTRACTED AND SYNTHESIZED. RESULTS: THIS REVIEW FOUND THAT YOGA WAS NOT SIGNIFICANTLY EFFECTIVE IN THE MANAGEMENT OF STRESS AMONG ORAL CANCER PATIENTS (P-VALUES > 0.04). HOWEVER, IT WAS FOUND THAT YOGA SIGNIFICANTLY REDUCED ANXIETY, SALIVA STICKINESS, AND EPISODES OF FALLING ILL (P-VALUES < 0.05) WHILE IT IMPROVED MENTAL WELL-BEING, COGNITIVE FUNCTIONING, EMOTIONAL FUNCTIONING, AND HEAD AND NECK PAIN OF THOSE ORAL CANCER PATIENTS THAT RECEIVED IT (P-VALUES < 0.05). CONCLUSION: AN INTEGRATIVE CARE APPROACH THAT CONSIDERS NONPHARMACEUTICAL TECHNIQUES SUCH AS YOGA COULD HELP TO REDUCE CARE COST WHILE IMPROVING CARE OUTCOMES AND QUALITY OF LIFE OF ORAL CANCER PATIENTS. HENCE, IT IS IMPERATIVE TO CONSIDER YOGA ALONG WITH ITS POTENTIAL BENEFITS, AND WE RECOMMEND GRADUAL INCORPORATION OF YOGA INTO ORAL CANCER CARE.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
6  2622  48 EPIGENOME-WIDE ASSOCIATION STUDIES IN ASTHMA: A SYSTEMATIC REVIEW. OBJECTIVE: ASTHMA IS A COMMON CHRONIC RESPIRATORY AIRWAY DISEASE INFLUENCED BY ENVIRONMENTAL FACTORS AND POSSIBLY THEIR INTERACTION WITH THE HUMAN GENOME CAUSING EPIGENETIC CHANGES. EPIGENOME-WIDE ASSOCIATION STUDIES (EWAS) HAVE MAINLY INVESTIGATED DNA METHYLATION AND ITS ASSOCIATION WITH DISEASE OR TRAITS, EXPOSURE FACTORS OR GENE EXPRESSION. THIS SYSTEMATIC REVIEW AIMED TO IDENTIFY ALL EWAS ASSESSING DIFFERENTIALLY METHYLATED SITES ASSOCIATED WITH ASTHMA IN HUMANS. DESIGN: STRUCTURED SYSTEMATIC LITERATURE SEARCH FOLLOWING PRISMA GUIDELINES, NEWCASTLE-OTTAWA SCALE (NOS) FOR COHORT STUDIES WAS USED FOR BIAS ASSESSMENT. DATA SOURCES: WE SEARCHED PUBMED AND EMBASE DATABASES FROM 2005 TO 2019. ELIGIBILITY CRITERIA: EPIGENOME-WIDE ASSOCIATION STUDIES TESTING ASSOCIATION BETWEEN DIFFERENTIAL METHYLATION AND ASTHMA IN HUMANS. RESULTS: OVERALL, WE IDENTIFIED 16 EWAS STUDIES COMPLYING WITH OUR SEARCH CRITERIA. TWELVE STUDIES WERE CONDUCTED ON CHILDREN, AND 10 WERE CONDUCTED ON SAMPLE SIZES <150 SUBJECTS. FOUR HUNDRED AND NINETEEN CPGS WERE REPORTED IN CHILDREN STUDIES AFTER CORRECTION FOR MULTIPLE TESTING. IN THE ADULT STUDIES, THOUSANDS OF DIFFERENTIALLY METHYLATED SITES WERE IDENTIFIED. DIFFERENTIAL METHYLATION IN INFLAMMATORY-RELATED GENES CORRELATED WITH HIGHER LEVELS OF GENE EXPRESSIONS OF INFLAMMATORY MODULATORS IN ASTHMA. DIFFERENTIALLY METHYLATED GENES ASSOCIATED WITH ASTHMA INCLUDED SMAD3, SERPINC1, PROK1, IL13, RUNX3 AND TIGIT. FORTY-ONE CPGS WERE REPLICATED AT LEAST ONCE IN BLOOD SAMPLES, AND 28 CPGS WERE REPLICATED IN NASAL SAMPLES. CONCLUSION: ALTHOUGH MANY DIFFERENTIALLY METHYLATED CPGS IN GENES KNOWN TO BE INVOLVED IN ASTHMA HAVE BEEN IDENTIFIED IN EWAS TO DATE, WE CONCLUDE THAT FURTHER STUDIES OF LARGER SAMPLE SIZES AND ANALYSES OF DIFFERENTIAL METHYLATION BETWEEN DIFFERENT PHENOTYPES ARE NEEDED IN ORDER TO COMPREHENSIVELY EVALUATE THE ROLE OF EPIGENETIC FACTORS IN THE PATHOPHYSIOLOGY AND HETEROGENEITY OF ASTHMA, AND THE POTENTIAL CLINICAL UTILITY TO PREDICT OR CLASSIFY PATIENTS WITH ASTHMA.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
7  5882  49 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.

8   639  48 BIOMARKERS FOR MYALGIC ENCEPHALOMYELITIS/CHRONIC FATIGUE SYNDROME (ME/CFS): A SYSTEMATIC REVIEW. BACKGROUND: MYALGIC ENCEPHALOMYELITIS/CHRONIC FATIGUE SYNDROME (ME/CFS) IS A MULTIFACETED CONDITION THAT AFFECTS MOST BODY SYSTEMS. THERE IS CURRENTLY NO KNOWN DIAGNOSTIC BIOMARKER; INSTEAD, DIAGNOSIS IS DEPENDENT ON APPLICATION OF SYMPTOM-BASED CASE CRITERIA FOLLOWING EXCLUSION OF ANY OTHER POTENTIAL MEDICAL CONDITIONS. WHILE THERE ARE SOME STUDIES THAT REPORT POTENTIAL BIOMARKERS FOR ME/CFS, THEIR EFFICACY HAS NOT BEEN VALIDATED. THE AIM OF THIS SYSTEMATIC REVIEW IS TO COLLATE AND APPRAISE LITERATURE PERTAINING TO A POTENTIAL BIOMARKER(S) WHICH MAY EFFECTIVELY DIFFERENTIATE ME/CFS PATIENTS FROM HEALTHY CONTROLS. METHODS: THIS SYSTEMATIC REVIEW WAS CONDUCTED ACCORDING TO THE PREFERRED REPORTING ITEMS FOR SYSTEMATIC REVIEWS AND META-ANALYSES AND COCHRANE REVIEW GUIDELINES. PUBMED, EMBASE AND SCOPUS WERE SYSTEMATICALLY SEARCHED FOR ARTICLES CONTAINING "BIOMARKER" AND "ME/CFS" KEYWORDS IN THE ABSTRACT OR TITLE AND IF THEY INCLUDED THE FOLLOWING CRITERIA: (1) WERE OBSERVATIONAL STUDIES PUBLISHED BETWEEN DECEMBER 1994 AND APRIL 2022; (2) INVOLVED ADULT HUMAN PARTICIPANTS; (3) FULL TEXT IS AVAILABLE IN ENGLISH (4) ORIGINAL RESEARCH; (5) DIAGNOSIS OF ME/CFS PATIENTS MADE ACCORDING TO THE FUKUDA CRITERIA (1994), CANADIAN CONSENSUS CRITERIA (2003), INTERNATIONAL CONSENSUS CRITERIA (2011) OR INSTITUTE OF MEDICINE CRITERIA (2015); (6) STUDY INVESTIGATED POTENTIAL BIOMARKERS OF ME/CFS COMPARED TO HEALTHY CONTROLS. QUALITY AND BIAS WERE ASSESSED USING THE JOANNA BRIGGS INSTITUTE CRITICAL APPRAISAL CHECKLIST FOR CASE CONTROL STUDIES. RESULTS: A TOTAL OF 101 PUBLICATIONS WERE INCLUDED IN THIS SYSTEMATIC REVIEW. POTENTIAL BIOMARKERS RANGED FROM GENETIC/EPIGENETIC (19.8%), IMMUNOLOGICAL (29.7%), METABOLOMICS/MITOCHONDRIAL/MICROBIOME (14.85%), ENDOVASCULAR/CIRCULATORY (17.82%), NEUROLOGICAL (7.92%), ION CHANNEL (8.91%) AND PHYSICAL DYSFUNCTION BIOMARKERS (8.91%). MOST OF THE POTENTIAL BIOMARKERS REPORTED WERE BLOOD-BASED (79.2%). USE OF LYMPHOCYTES AS A MODEL TO INVESTIGATE ME/CFS PATHOLOGY WAS PROMINENT AMONG IMMUNE-BASED BIOMARKERS. MOST BIOMARKERS HAD SECONDARY (43.56%) OR TERTIARY (54.47%) SELECTIVITY, WHICH IS THE ABILITY FOR THE BIOMARKER TO IDENTIFY A DISEASE-CAUSING AGENT, AND A MODERATE (59.40%) TO COMPLEX (39.60%) EASE-OF-DETECTION, INCLUDING THE REQUIREMENT OF SPECIALISED EQUIPMENT. CONCLUSIONS: ALL POTENTIAL ME/CFS BIOMARKERS DIFFERED IN EFFICIENCY, QUALITY, AND TRANSLATABILITY AS A DIAGNOSTIC MARKER. REPRODUCIBILITY OF FINDINGS BETWEEN THE INCLUDED PUBLICATIONS WERE LIMITED, HOWEVER, SEVERAL STUDIES VALIDATED THE INVOLVEMENT OF IMMUNE DYSFUNCTION IN THE PATHOLOGY OF ME/CFS AND THE USE OF LYMPHOCYTES AS A MODEL TO INVESTIGATE THE PATHOMECHANISM OF ILLNESS. THE HETEROGENEITY SHOWN ACROSS MANY OF THE INCLUDED STUDIES HIGHLIGHTS THE NEED FOR MULTIDISCIPLINARY RESEARCH AND UNIFORM PROTOCOLS IN ME/CFS BIOMARKER RESEARCH.	2023	

9   121  42 A SYSTEMATIC REVIEW OF TRANSCRIPTIONAL DYSREGULATION IN HUNTINGTON'S DISEASE STUDIED BY RNA SEQUENCING. HUNTINGTON'S DISEASE (HD) IS A CHRONIC NEURODEGENERATIVE DISORDER CAUSED BY AN EXPANSION OF POLYGLUTAMINE REPEATS IN EXON 1 OF THE HUNTINGTIN GENE. TRANSCRIPTIONAL DYSREGULATION ACCOMPANIED BY EPIGENETIC ALTERATIONS IS AN EARLY AND CENTRAL DISEASE MECHANISM IN HD YET, THE EXACT MECHANISMS AND REGULATORS, AND THEIR ASSOCIATED GENE EXPRESSION PROGRAMS REMAIN INCOMPLETELY UNDERSTOOD. THIS SYSTEMATIC REVIEW INVESTIGATES GENOME-WIDE TRANSCRIPTIONAL STUDIES THAT WERE CONDUCTED USING RNA SEQUENCING (RNA-SEQ) TECHNOLOGY IN HD PATIENTS AND MODELS. THE REVIEW PROTOCOL WAS REGISTERED AT THE OPEN SCIENCE FRAMEWORK (OSF). THE BIOMEDICAL LITERATURE AND GENE EXPRESSION DATABASES, PUBMED AND NCBI BIOPROJECT, ARRAY EXPRESS, EUROPEAN NUCLEOTIDE ARCHIVE (ENA), EUROPEAN GENOME-PHENOME ARCHIVE (EGA), RESPECTIVELY, WERE SEARCHED USING THE DEFINED TERMS SPECIFIED IN THE PROTOCOL FOLLOWING THE PRISMA GUIDELINES. WE CONDUCTED A COMPLETE LITERATURE AND DATABASE SEARCH TO RETRIEVE ALL RNA-SEQ-BASED GENE EXPRESSION STUDIES IN HD PUBLISHED UNTIL AUGUST 2020, RETRIEVING 288 ARTICLES AND 237 DATASETS FROM PUBMED AND THE DATABASES, RESPECTIVELY. A TOTAL OF 27 STUDIES MEETING THE ELIGIBILITY CRITERIA WERE INCLUDED IN THIS REVIEW. COLLECTIVELY, COMPARATIVE ANALYSIS OF THE DATASETS REVEALED FREQUENT GENES THAT ARE CONSISTENTLY DYSREGULATED IN HD. IN POSTMORTEM BRAINS FROM HD PATIENTS, DNAJB1, HSPA1B AND HSPB1 GENES WERE COMMONLY UPREGULATED ACROSS ALL BRAIN REGIONS AND CELL TYPES EXCEPT FOR MEDIUM SPINY NEURONS (MSNS) AT SYMPTOMATIC DISEASE STAGE, AND HSPH1 AND SAT1 GENES WERE ALTERED IN EXPRESSION IN ALL SYMPTOMATIC BRAIN DATASETS, INDICATING EARLY AND SUSTAINED CHANGES IN THE EXPRESSION OF GENES RELATED TO HEAT SHOCK RESPONSE AS WELL AS RESPONSE TO MISFOLDED PROTEINS. SPECIFICALLY IN INDIRECT PATHWAY MEDIUM SPINY NEURONS (IMSNS), MITOCHONDRIA RELATED GENES WERE AMONG THE TOP UNIQUELY DYSREGULATED GENES. INTERESTINGLY, BLOOD FROM HD PATIENTS SHOWED COMMONLY DIFFERENTIALLY EXPRESSED GENES WITH A NUMBER OF BRAIN REGIONS AND CELLS, WITH THE HIGHEST NUMBER OF OVERLAPPING GENES WITH MSNS AND BA9 REGION AT SYMPTOMATIC STAGE. WE ALSO FOUND THE DIFFERENTIAL EXPRESSION AND PREDICTED ALTERED ACTIVITY OF A SET OF TRANSCRIPTION FACTORS AND EPIGENETIC REGULATORS, INCLUDING BCL6, EGR1, FOSL2 AND CREBBP, HDAC1, KDM4C, RESPECTIVELY, WHICH MAY UNDERLIE THE OBSERVED TRANSCRIPTIONAL CHANGES IN HD. ALTOGETHER, OUR WORK PROVIDES A COMPLETE OVERVIEW OF THE TRANSCRIPTIONAL STUDIES IN HD, AND BY DATA SYNTHESIS, REVEALS A NUMBER OF COMMON AND UNIQUE GENE EXPRESSION AND REGULATORY CHANGES ACROSS DIFFERENT CELL AND TISSUE TYPES IN HD. THESE CHANGES COULD ELUCIDATE NEW INSIGHTS INTO MOLECULAR MECHANISMS OF DIFFERENTIAL VULNERABILITY IN HD.

10  2108  37 EPIGENETIC FACTORS RELATED TO LOW BACK PAIN: A SYSTEMATIC REVIEW OF THE CURRENT LITERATURE. LOW BACK PAIN (LBP) IS ONE OF THE MOST COMMON CAUSES OF PAIN AND DISABILITY. AT PRESENT, TREATMENT AND INTERVENTIONS FOR ACUTE AND CHRONIC LOW BACK PAIN OFTEN FAIL TO PROVIDE SUFFICIENT LEVELS OF PAIN RELIEF, AND FULL FUNCTIONAL RESTORATION CAN BE CHALLENGING. CONSIDERING THE SIGNIFICANT SOCIO-ECONOMIC BURDEN AND RISK-TO-BENEFIT RATIO OF MEDICAL AND SURGICAL INTERVENTION IN LOW BACK PAIN PATIENTS, THE IDENTIFICATION OF RELIABLE BIOMARKERS SUCH AS EPIGENETIC FACTORS ASSOCIATED WITH LOW BACK PAIN COULD BE USEFUL IN CLINICAL PRACTICE. THE AIM OF THIS STUDY WAS TO REVIEW THE AVAILABLE LITERATURE REGARDING THE EPIGENETIC FACTORS ASSOCIATED WITH LOW BACK PAIN. THIS REVIEW WAS CARRIED OUT IN ACCORDANCE WITH PREFERENTIAL REPORTING ITEMS FOR SYSTEMATIC REVIEWS AND META-ANALYSES (PRISMA) GUIDELINES. THE SEARCH WAS CARRIED OUT IN OCTOBER 2022. ONLY PEER-REVIEWED ARTICLES WERE CONSIDERED FOR INCLUSION. FOURTEEN STUDIES WERE INCLUDED AND SHOWED PROMISING RESULTS IN TERMS OF RELIABLE MARKERS. EPIGENETIC MARKERS FOR LBP HAVE THE POTENTIAL TO SIGNIFICANTLY MODIFY DISEASE MANAGEMENT. MOST RECENT EVIDENCE SUGGESTS THAT EPIGENETICS IS A MORE PROMISING FIELD FOR THE IDENTIFICATION OF FACTORS ASSOCIATED WITH LBP, OFFERING A RATIONALE FOR FURTHER INVESTIGATION IN THIS FIELD WITH THE LONG-TERM GOAL OF FINDING EPIGENETIC BIOMARKERS THAT COULD CONSTITUTE BIOLOGICAL TARGETS FOR DISEASE MANAGEMENT AND TREATMENT.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
11  1998  42 EPIGENETIC AND MIRNA EXPRESSION CHANGES IN PEOPLE WITH PAIN: A SYSTEMATIC REVIEW. ACCUMULATING EVIDENCE SUGGESTS THAT EPIGENETIC MECHANISMS MAY HOLD GREAT POTENTIAL IN THE FIELD OF PAIN. WE SYSTEMATICALLY REVIEWED THE LITERATURE EXPLORING EPIGENETIC MECHANISMS IN PEOPLE WITH PAIN. FOUR DATABASES HAVE BEEN INTERROGATED: MEDLINE, THE COCHRANE CENTRAL REGISTER OF CONTROLLED TRIAL, SCOPUS, AND WEB OF SCIENCE, FOLLOWING PRISMA GUIDELINES IN CONDUCTING STUDY SELECTION AND ASSESSMENT. THIRTY-SEVEN STUDIES WERE INCLUDED. STUDIES EXPLORED EPIGENETICS IN CONDITIONS SUCH AS FIBROMYALGIA, CRPS, NEUROPATHIES, OR OSTEOARTHRITIS. RESEARCH FOCUSSED ON GENOME-WIDE AND GENE-SPECIFIC DNA METHYLATION, AND MIRNA EXPRESSION. BIOINFORMATICS ANALYSES EXPLORING MIRNA-ASSOCIATED MOLECULAR PATHWAYS WERE ALSO PERFORMED. SEVERAL GENES ALREADY KNOWN FOR THEIR ROLE IN PAIN (BDNF, HDAC4, PRKG1, IL-17, TNFRSF13B, ETC.), AND SEVERAL MIRNAS LINKED TO INFLAMMATORY REGULATION, NOCICEPTIVE SIGNALLING AND PROTEIN KINASES FUNCTIONS HAVE BEEN FOUND TO DIFFER SIGNIFICANTLY BETWEEN PEOPLE WITH CHRONIC PAIN AND HEALTHY CONTROLS. ALTHOUGH THE STUDIES INCLUDED WERE CROSS-SECTIONAL IN NATURE, AND NO CONCLUSION ON CAUSAL LINKS BETWEEN EPIGENETIC CHANGES AND PAIN COULD BE DRAWN, WE SUMMARISED THE LARGE AMOUNT OF DATA AVAILABLE IN LITERATURE ON THE TOPIC, HIGHLIGHTING RESULTS THAT HAVE BEEN REPLICATED BY INDEPENDENT INVESTIGATIONS. THE FIELD OF PAIN EPIGENETICS APPEARS VERY EXCITING AND HAS ALL THE POTENTIAL TO LEAD TO REMARKABLE SCIENTIFIC ADVANCES. HOWEVER, HIGH-QUALITY, WELL-POWERED, LONGITUDINAL STUDIES ARE WARRANTED. PERSPECTIVE: THOUGH MORE HIGH-QUALITY RESEARCH IS NEEDED, AVAILABLE RESEARCH EXPLORING EPIGENETIC MECHANISMS OR MIRNAS IN PEOPLE WITH PAIN SHOWS THAT GENES REGULATING SYNAPTIC PLASTICITY AND EXCITABILITY, PROTEIN KINASES, AND ELEMENTS OF THE IMMUNE SYSTEM MIGHT HOLD GREAT POTENTIAL IN UNDERSTANDING THE PATHOPHYSIOLOGY OF DIFFERENT CONDITIONS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
12  2093  42 EPIGENETIC EFFECTS FOLLOWING ACUTE AND CHRONIC EXERCISE IN CARDIOVASCULAR DISEASE: A SYSTEMATIC REVIEW. INTRODUCTION: ACUTE EXERCISE AND EXERCISE TRAINING MAY CONFER EPIGENETIC MODIFICATIONS IN HEALTHY SUBJECTS. EPIGENETIC EFFECTS AFTER EXERCISE HAVE BEEN SHOWED IN PATIENTS WITH CARDIOVASCULAR DISEASE. THE AIM OF THIS SYSTEMATIC REVIEW WAS TO SUMMARIZE THE EVIDENCE FROM AVAILABLE CLINICAL TRIALS THAT STUDY EPIGENETIC ADAPTATIONS AFTER EXERCISE IN PATIENTS WITH CARDIOVASCULAR DISEASE. METHODS: THE SEARCH STRATEGY WAS PERFORMED IN PUBMED AND CENTRAL DATABASES ON ARTICLES PUBLISHED UNTIL SEPTEMBER 2020. STUDIES WITH TITLES AND ABSTRACTS RELEVANT TO EXERCISE EPIGENETIC MODIFICATION APPLIED TO CARDIOVASCULAR PATIENTS WERE FULLY EXAMINED. INCLUSION AND EXCLUSION CRITERIA WERE UTILIZED FOR STUDIES SCREENING. QUALITY ASSESSMENT WITH PEDRO SCALE AND EVALUATION BY TWO INDEPENDENT REVIEWERS WAS PERFORMED. RESULTS: OF THE 1714 ARTICLES RETRIEVED, 88 ARTICLES WERE ASSESSED FOR ELIGIBILITY CRITERIA AND 8 ARTICLES MATCHED OUR SEARCH CRITERIA AND FINALLY INCLUDED IN THE SYSTEMATIC ANALYSIS. THE ACUTE EXERCISE EPIGENETIC (MIRNAS) EFFECTS WERE ASSESSED IN THREE STUDIES AND THE CHRONIC EXERCISE TRAINING EFFECTS (MIRNAS AND DNA METHYLATION) IN SIX STUDIES. THE RESULTS HAVE SHOWN THAT THERE IS POSSIBLY AN ACUTE SIGNIFICANT EXERCISE EFFECT ON EPIGENETIC TARGETS WHICH IS MORE EVIDENT AFTER CHRONIC EXERCISE TRAINING. CONCLUSIONS: BY THE PRESENT SYSTEMATIC REVIEW, WE PROVIDE PRELIMINARY EVIDENCE OF BENEFICIAL EPIGENETIC ADAPTATIONS FOLLOWING ACUTE AND CHRONIC EXERCISE IN PATIENTS WITH CARDIOVASCULAR DISEASE. MORE CONTROLLED STUDIES ARE NEEDED TO CONFIRM SUCH EVIDENCE.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
13  2646  33 EPIGENOMIC LINKS BETWEEN SOCIAL DETERMINANTS OF HEALTH AND SYMPTOMS: A SCOPING REVIEW. SOCIAL DETERMINANTS OF HEALTH (SDOH) IMPACT HEALTH AND WELLNESS. THE LINK BETWEEN SDOH AND ADVERSE HEALTH OUTCOMES, INCLUDING SYMPTOM OCCURRENCE AND SEVERITY, MAY BE EXPLAINED BY AN INDIVIDUAL'S PHYSIOLOGIC RESPONSE TO ONE OR MORE SDOH. ONE POTENTIAL MECHANISM UNDERLYING THIS PHYSIOLOGIC RESPONSE LINKING SDOH AND SYMPTOMS IS THE DYNAMIC EPIGENOME. THE PURPOSE OF THIS SCOPING REVIEW OF THE LITERATURE WAS TO EXAMINE DIFFERENTIAL SUSCEPTIBILITY FOR SYMPTOMS BY IDENTIFYING AND SUMMARIZING RESEARCH LINKING SDOH AND SYMPTOMS THROUGH EPIGENOMIC MECHANISMS. PUBMED WAS SEARCHED TO IDENTIFY EMPIRICAL RESEARCH WHERE AT LEAST ONE SDOH WAS AN INDEPENDENT OR DEPENDENT VARIABLE, AT LEAST ONE SYMPTOM WAS INVESTIGATED, AND THE INVESTIGATION INCLUDED AN EPIGENOMIC MEASURE. OF THE 484 ARTICLES INITIALLY RETRIEVED, AFTER THOROUGH VETTING, 41 ARTICLES MET ELIGIBILITY. THE MOST STUDIED SYMPTOM WAS DEPRESSIVE SYMPTOMS FOLLOWED BY ANXIETY, COGNITIVE FUNCTION, SLEEP DYSFUNCTION, AND PAIN. THE MOST FREQUENTLY STUDIED SDOH WERE: 1) STRESS, PARTICULARLY EARLY LIFE STRESS AND ACCULTURATIVE STRESS; AND 2) TRAUMA, PREDOMINANTLY CHILDHOOD TRAUMA. DNA METHYLATION AND TELOMERE LENGTH WERE THE MOST STUDIED EPIGENOMIC MEASURES. FOUR GENES (SLC6A4, BDNF, NR3C1, OXTR) HAD EVIDENCE FROM MULTIPLE STUDIES AND ACROSS METHODOLOGICAL APPROACHES LINKING SDOH TO SYMPTOMS. THIS REVIEW SUPPORTS THE INCLUSION OF EPIGENOMIC APPROACHES TO BETTER UNDERSTAND THE LINK BETWEEN SDOH AND SYMPTOMS AND PROVIDES EVIDENCE THAT SDOH IMPACT TELOMERE LENGTH AND THE METHYLATION OF GENES INVOLVED IN NEUROTRANSMITTER SIGNALING, NEURONAL SURVIVAL, BEHAVIOR, INFLAMMATION AND STRESS RESPONSE.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
14  1517  44 DNA METHYLATION AS A MEDIATOR OF ASSOCIATIONS BETWEEN THE ENVIRONMENT AND CHRONIC DISEASES: A SCOPING REVIEW ON APPLICATION OF MEDIATION ANALYSIS. DNA METHYLATION (DNAM) IS ONE OF THE MOST STUDIED EPIGENETIC MODIFICATIONS. DNAM HAS EMERGED AS A KEY BIOLOGICAL MECHANISM AND BIOMARKERS TO TEST ASSOCIATIONS BETWEEN ENVIRONMENTAL EXPOSURE AND OUTCOMES IN EPIDEMIOLOGICAL STUDIES. ALTHOUGH PREVIOUS STUDIES HAVE FOCUSED ON ASSOCIATIONS BETWEEN DNAM AND EITHER EXPOSURE/OUTCOMES, IT IS USEFUL TO TEST FOR MEDIATION OF THE ASSOCIATION BETWEEN EXPOSURE AND OUTCOME BY DNAM. THE PURPOSE OF THIS SCOPING REVIEW IS TO INTRODUCE THE METHODOLOGICAL ESSENCE OF STATISTICAL MEDIATION ANALYSIS AND TO EXAMINE EMERGING EPIDEMIOLOGICAL RESEARCH APPLYING MEDIATION ANALYSES. WE CONDUCTED THIS SCOPING REVIEW FOR PUBLISHED PEER-REVIEWED JOURNALS ON THIS TOPIC USING ONLINE DATABASES (PUBMED, SCOPUS, COCHRANE, AND CINAHL) ENDING IN DECEMBER 2020. WE EXTRACTED A TOTAL OF 219 ARTICLES BY INITIAL SCREENING. AFTER REVIEWING TITLES, ABSTRACTS, AND FULL TEXTS, A TOTAL OF 69 ARTICLES WERE ELIGIBLE FOR THIS REVIEW. THE BREAKDOWN OF STUDIES ASSIGNED TO EACH CATEGORY WAS 13 FOR SMOKING (18.8%), 8 FOR DIETARY INTAKE AND FAMINE (11.6%), 6 FOR OTHER LIFESTYLE FACTORS (8.7%), 8 FOR CLINICAL ENDPOINTS (11.6%), 22 FOR ENVIRONMENTAL CHEMICAL EXPOSURES (31.9%), 2 FOR SOCIOECONOMIC STATUS (SES) (2.9%), AND 10 FOR GENETIC FACTORS AND RACE (14.5%). IN THIS REVIEW, WE PROVIDE AN EXPOSURE-WIDE SUMMARY FOR THE MEDIATION ANALYSIS USING DNAM LEVELS. HOWEVER, WE FOUND HETEROGENOUS METHODS AND INTERPRETATIONS IN MEDIATION ANALYSIS WITH TYPICAL ISSUES SUCH AS DIFFERENT CELL COMPOSITIONS AND TISSUE-SPECIFICITY. FURTHER ACCUMULATION OF EVIDENCE WITH DIVERSE EXPOSURES, POPULATIONS AND WITH RIGOROUS METHODOLOGY WILL BE EXPECTED TO PROVIDE FURTHER INSIGHT IN THE ROLE OF DNAM IN DISEASE SUSCEPTIBILITY.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
15  1971  38 EPIGENETIC ALTERATIONS ASSOCIATED WITH CHILDHOOD TRAUMA AND ADULT MENTAL HEALTH OUTCOMES: A SYSTEMATIC REVIEW. OBJECTIVES: MULTIPLE, CHRONIC AND REPEATED TRAUMA EXPOSURE IN CHILDHOOD IS ASSOCIATED WITH ADVERSE MENTAL HEALTH OUTCOMES IN ADULTHOOD. IN THIS PAPER WE SYNTHESISE THE LITERATURE ON EPIGENETIC MODIFICATIONS IN CHILDHOOD TRAUMA (CT) AND THE MEDIATING EFFECTS OF DIFFERENTIAL EPIGENETIC MECHANISMS ON THE ASSOCIATION BETWEEN CT AND THE LATER ONSET OF PSYCHIATRIC DISORDERS.METHODS: WE REVIEWED THE LITERATURE UP TO MARCH 2018 IN FOUR DATABASES: PUBMED, WEB OF SCIENCE, EBSCOHOST AND SCOPUS. NON-HUMAN STUDIES WERE EXCLUDED. ALL STUDIES INVESTIGATING CT EXPOSURE BOTH IN HEALTHY ADULTS (18 YEARS AND OLDER) AND ADULTS WITH PSYCHIATRIC DISORDERS WERE INCLUDED.RESULTS: THIRTY-SIX PUBLICATIONS WERE INCLUDED. FOR MOOD DISORDERS, METHYLATION OF THE GLUCOCORTICOID RECEPTOR NR3C1 GENE, SPECIFICALLY AT THE NGFI-A BINDING SITE IN EXON 1F, AND CORRELATION WITH CT WAS A ROBUST FINDING. SEVERAL STUDIES DOCUMENTED DIFFERENTIAL METHYLATION OF SLC6A4, BDNF, OXTR AND FKBP5 IN ASSOCIATION WITH CT. COMMON PATHWAYS IDENTIFIED INCLUDE NEURONAL FUNCTIONING AND MAINTENANCE, IMMUNE AND INFLAMMATORY PROCESSES, CHROMATIN AND HISTONE MODIFICATION, AND TRANSCRIPTION FACTOR BINDING.CONCLUSIONS: A VARIETY OF EPIGENETIC MEDIATORS THAT LIE ON A COMMON PATHWAY BETWEEN CT AND PSYCHIATRIC DISORDERS HAVE BEEN IDENTIFIED, ALTHOUGH LONGITUDINAL STUDIES AND CONSISTENCY IN METHODOLOGICAL APPROACH ARE NEEDED TO DISENTANGLE CAUSE AND EFFECT ASSOCIATIONS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
16  6524  45 TRANSCRIPTIONAL AND EPIGENETIC RESPONSE TO SEDENTARY BEHAVIOR AND PHYSICAL ACTIVITY IN CHILDREN AND ADOLESCENTS: A SYSTEMATIC REVIEW. BACKGROUND: THE LINKS OF SEDENTARY BEHAVIOR AND PHYSICAL ACTIVITY WITH HEALTH OUTCOMES IN CHILDREN AND ADOLESCENTS IS WELL KNOWN. HOWEVER, THE MOLECULAR MECHANISMS INVOLVED ARE POORLY UNDERSTOOD. WE AIMED TO SYNTHESIZE THE CURRENT KNOWLEDGE OF THE ASSOCIATION OF SEDENTARY BEHAVIOR AND PHYSICAL ACTIVITY (ACUTE AND CHRONIC EFFECTS) WITH GENE EXPRESSION AND EPIGENETIC MODIFICATIONS IN CHILDREN AND ADOLESCENTS. METHODS: PUBMED, WEB OF SCIENCE, AND SCOPUS DATABASES WERE SYSTEMATICALLY SEARCHED UNTIL APRIL 2022. A TOTAL OF 15 ARTICLES WERE ELIGIBLE FOR THIS REVIEW. THE RISK OF BIAS ASSESSMENT WAS PERFORMED USING THE JOANNA BRIGGS INSTITUTE CRITICAL APPRAISAL TOOL FOR SYSTEMATIC REVIEWS AND/OR A MODIFIED VERSION OF THE DOWNS AND BLACK CHECKLIST. RESULTS: THIRTEEN STUDIES USED CANDIDATE GENE APPROACH, WHILE ONLY 2 STUDIES PERFORMED HIGH-THROUGHPUT ANALYSES. THE CANDIDATE GENES SIGNIFICANTLY LINKED TO SEDENTARY BEHAVIOR OR PHYSICAL ACTIVITY WERE: FOXP3, HSD11B2, IL-10, TNF-ALPHA, ADRB2, VEGF, HSP70, SOX, AND GPX. NON-CODING RIBONUCLEIC ACIDS (RNAS) REGULATED BY SEDENTARY BEHAVIOR OR PHYSICAL ACTIVITY WERE: MIRNA-222, MIRNA-146(A), MIRNA-16, MIRNA-126, MIR-320(A), AND LONG NON-CODING RNA MALAT1. THESE MOLECULES ARE INVOLVED IN INFLAMMATION, IMMUNE FUNCTION, ANGIOGENIC PROCESS, AND CARDIOVASCULAR DISEASE. TRANSCRIPTOMICS ANALYSES DETECTED THOUSANDS OF GENES THAT WERE ALTERED FOLLOWING AN ACUTE BOUT OF PHYSICAL ACTIVITY AND ARE LINKED TO GENE PATHWAYS RELATED TO IMMUNE FUNCTION, APOPTOSIS, AND METABOLIC DISEASES. CONCLUSION: THE EVIDENCE FOUND TO DATE IS RATHER LIMITED. MULTIDISCIPLINARY STUDIES ARE ESSENTIAL TO CHARACTERIZE THE MOLECULAR MECHANISMS IN RESPONSE TO SEDENTARY BEHAVIOR AND PHYSICAL ACTIVITY IN THE PEDIATRIC POPULATION. LARGER COHORTS AND RANDOMIZED CONTROLLED TRIALS, IN COMBINATION WITH MULTI-OMICS ANALYSES, MAY PROVIDE THE NECESSARY DATA TO BRING THE FIELD FORWARD.

17   502  37 ASSOCIATION OF ARSENIC EXPOSURE WITH WHOLE BLOOD DNA METHYLATION: AN EPIGENOME-WIDE STUDY OF BANGLADESHI ADULTS. BACKGROUND: ARSENIC EXPOSURE AFFECTS [FORMULA: SEE TEXT] PEOPLE WORLDWIDE, INCLUDING [FORMULA: SEE TEXT] IN BANGLADESH. ARSENIC EXPOSURE INCREASES THE RISK OF CANCER AND OTHER CHRONIC DISEASES, AND ONE POTENTIAL MECHANISM OF ARSENIC TOXICITY IS EPIGENETIC DYSREGULATION. OBJECTIVE: WE ASSESSED ASSOCIATIONS BETWEEN ARSENIC EXPOSURE AND GENOME-WIDE DNA METHYLATION MEASURED AT BASELINE AMONG 396 BANGLADESHI ADULTS PARTICIPATING IN THE HEALTH EFFECTS OF ARSENIC LONGITUDINAL STUDY (HEALS) WHO WERE EXPOSED BY DRINKING NATURALLY CONTAMINATED WELL WATER. METHODS: METHYLATION IN WHOLE BLOOD DNA WAS MEASURED AT [FORMULA: SEE TEXT] USING THE ILLUMINA INFINIUMMETHYLATIONEPIC (EPIC) ARRAY. TO ASSESS ASSOCIATIONS BETWEEN ARSENIC EXPOSURE AND CPG METHYLATION, WE USED LINEAR REGRESSION MODELS ADJUSTED FOR COVARIATES AND SURROGATE VARIABLES (SVS) (CAPTURING UNKNOWN TECHNICAL AND BIOLOGIC FACTORS). WE ATTEMPTED REPLICATION AND CONDUCTED A META-ANALYSIS USING AN INDEPENDENT DATASET OF [FORMULA: SEE TEXT] FROM 400 BANGLADESHI INDIVIDUALS WITH ARSENICAL SKIN LESIONS. RESULTS: WE IDENTIFIED 34 CPGS ASSOCIATED WITH [FORMULA: SEE TEXT] CREATININE-ADJUSTED URINARY ARSENIC [[FORMULA: SEE TEXT]]. SIXTEEN OF THESE CPGS ANNOTATED TO THE [FORMULA: SEE TEXT] ARRAY, AND 10 ASSOCIATIONS WERE REPLICATED ([FORMULA: SEE TEXT]). THE TOP TWO CPGS ANNOTATED UPSTREAM OF THE ABR GENE (CG01912040, CG10003262 ). ALL URINARY ARSENIC-ASSOCIATED CPGS WERE ALSO ASSOCIATED WITH ARSENIC CONCENTRATION MEASURED IN DRINKING WATER ([FORMULA: SEE TEXT]). META-ANALYSIS ([FORMULA: SEE TEXT] SAMPLES) IDENTIFIED 221 URINARY ARSENIC-ASSOCIATED CPGS ([FORMULA: SEE TEXT]). THE ARSENIC-ASSOCIATED CPGS FROM THE META-ANALYSIS WERE ENRICHED IN NON-CPG ISLANDS AND SHORES ([FORMULA: SEE TEXT]) AND DEPLETED IN PROMOTER REGIONS ([FORMULA: SEE TEXT]). AMONG THE ARSENIC-ASSOCIATED CPGS ([FORMULA: SEE TEXT]), WE OBSERVED SIGNIFICANT ENRICHMENT OF GENES ANNOTATING TO THE REACTIVE OXYGEN SPECIES PATHWAY, INFLAMMATORY RESPONSE, AND TUMOR NECROSIS FACTOR [FORMULA: SEE TEXT] ([FORMULA: SEE TEXT]) SIGNALING VIA NUCLEAR FACTOR KAPPA-B ([FORMULA: SEE TEXT]) HALLMARKS ([FORMULA: SEE TEXT]). CONCLUSIONS: THE NOVEL AND REPLICABLE ASSOCIATIONS BETWEEN ARSENIC EXPOSURE AND DNA METHYLATION AT SPECIFIC CPGS OBSERVED IN THIS WORK SUGGEST THAT EPIGENETIC ALTERATIONS SHOULD BE FURTHER INVESTIGATED AS POTENTIAL MEDIATORS IN ARSENIC TOXICITY AND AS BIOMARKERS OF EXPOSURE AND EFFECT IN EXPOSED POPULATIONS.

18  4926  42 PARKINSON'S DISEASE AND SARS-COV-2 INFECTION: PARTICULARITIES OF MOLECULAR AND CELLULAR MECHANISMS REGARDING PATHOGENESIS AND TREATMENT. ACCUMULATING DATA SUGGEST THAT CHRONIC NEUROINFLAMMATION-MEDIATED NEURODEGENERATION IS A SIGNIFICANT CONTRIBUTING FACTOR FOR PROGRESSIVE NEURONAL AND GLIAL CELL DEATH IN AGE-RELATED NEURODEGENERATIVE PATHOLOGY. FURTHERMORE, IT COULD BE ENCOUNTERED AS LONG-TERM CONSEQUENCES IN SOME VIRAL INFECTIONS, INCLUDING POST-COVID-19 PARKINSONISM-RELATED CHRONIC SEQUELAE. THE CURRENT SYSTEMATIC REVIEW IS FOCUSED ON A RECENT QUESTION AROUSED DURING THE PANDEMIC'S SUCCESSIVE WAVES: ARE THERE POST-SARS-COV-2 IMMUNE-MEDIATED REACTIONS RESPONSIBLE FOR PROMOTING NEURODEGENERATION? DOES THE HOST'S DYSREGULATED IMMUNE COUNTER-OFFENSIVE CONTRIBUTE TO THE PATHOGENESIS OF NEURODEGENERATIVE DISEASES, EMERGING AS PARKINSON'S DISEASE, IN A COMPLEX INTERRELATION BETWEEN GENETIC AND EPIGENETIC RISK FACTORS? A SYNTHETIC AND SYSTEMATIC LITERATURE REVIEW WAS ACCOMPLISHED BASED ON THE "PREFERRED REPORTING ITEMS FOR SYSTEMATIC PRINCIPLES REVIEWS AND META-ANALYSES" (PRISMA) METHODOLOGY, INCLUDING REGISTRATION ON THE SPECIFIC ONLINE PLATFORM: INTERNATIONAL PROSPECTIVE REGISTER OF SYSTEMATIC REVIEWS-PROSPERO, NO. 312183. INITIALLY, 1894 ARTICLES WERE DETECTED. AFTER FULFILLING THE FIVE STEPS OF THE SELECTION METHODOLOGY, 104 PAPERS WERE SELECTED FOR THIS SYNTHETIC REVIEW. DOCUMENTATION WAS ENHANCED WITH A SUPPLEMENTARY 47 BIBLIOGRAPHIC RESOURCES IDENTIFIED IN THE LITERATURE WITHIN A NON-STANDARDIZED SEARCH CONNECTED TO THE SUBJECT. AS A FINAL STEP OF THE PRISMA METHOD, WE HAVE FULFILLED A POPULATION-INTERVENTION-COMPARISON-OUTCOME-TIME (PICOT)/POPULATION-INTERVENTION-COMPARISON-OUTCOME-STUDY TYPE (PICOS)-BASED METANALYSIS OF CLINICAL TRIALS IDENTIFIED AS CONNECTED TO OUR SEARCH, TARGETING THE OUTCOMES OF REHABILITATIVE KINESITHERAPEUTIC INTERVENTIONS COMPARED TO CLINICAL APPROACHES LACKING SUCH KIND OF TREATMENT. ACCORDINGLY, WE IDENTIFIED 10 CLINICAL TRIALS RELATED TO OUR ARTICLE. THE MULTI/INTERDISCIPLINARY CONVENTIONAL THERAPY OF PARKINSON'S DISEASE AND NON-CONVENTIONAL MULTITARGET APPROACH TO AN INTEGRATIVE TREATMENT WAS BRIEFLY ANALYZED. THIS ARTICLE SYNTHESIZES THE CURRENT FINDINGS ON THE PATHOGENIC INTERFERENCE BETWEEN THE DYSREGULATED COMPLEX MECHANISMS INVOLVED IN AGING, NEUROINFLAMMATION, AND NEURODEGENERATION, FOCUSING ON PARKINSON'S DISEASE AND THE ACUTE AND CHRONIC REPERCUSSIONS OF COVID-19. TIME WILL TELL WHETHER COVID-19 NEUROINFLAMMATORY EVENTS COULD TRIGGER LONG-TERM NEURODEGENERATIVE EFFECTS AND CONTRIBUTE TO THE WORSENING AND/OR EXPLOSION OF NEW CASES OF PD. THE EXTENT OF THE INTERRELATED NEUROPATHOGENIC PHENOMENON REMAINS OBSCURE, SO FURTHER CLINICAL OBSERVATIONS AND PROSPECTIVE LONGITUDINAL COHORT STUDIES ARE NEEDED.	2022	
                                                                                                                                                                            
19  2510  40 EPIGENETICS AND POSTSURGICAL PAIN: A SCOPING REVIEW. OBJECTIVE: MULTIPLE FACTORS ARE INVOLVED IN THE PHYSIOLOGY AND VARIABILITY OF POSTSURGICAL PAIN, A GREAT PART OF WHICH CAN BE EXPLAINED BY GENETIC AND ENVIRONMENTAL FACTORS AND THEIR INTERACTION. EPIGENETICS REFERS TO THE MECHANISM BY WHICH THE ENVIRONMENT ALTERS THE STABILITY AND EXPRESSION OF GENES. WE CONDUCTED A SCOPING REVIEW TO EXAMINE THE AVAILABLE EVIDENCE IN BOTH ANIMAL MODELS AND CLINICAL STUDIES ON EPIGENETIC MECHANISMS INVOLVED IN THE REGULATION OF POSTSURGICAL AND CHRONIC POSTSURGICAL PAIN. METHODS: THE ARKSEY AND O'MALLEY FRAMEWORK AND THE PRISMA-SCR (PREFERRED REPORTING ITEMS FOR SYSTEMATIC REVIEW AND META-ANALYSIS, SCOPING REVIEWS EXTENSION) GUIDELINES WERE USED. THE PUBMED, WEB OF SCIENCE, AND GOOGLE SCHOLAR DATABASES WERE SEARCHED, AND THE ORIGINAL ARTICLES CITED IN REVIEWS LOCATED THROUGH THE SEARCH WERE ALSO REVIEWED. ENGLISH-LANGUAGE ARTICLES WITHOUT TIME LIMITS WERE RETRIEVED. ARTICLES WERE SELECTED IF THE ABSTRACT ADDRESSED INFORMATION ON THE EPIGENETIC OR EPIGENOMIC MECHANISMS, HISTONE, OR DNA METHYLATION AND MICRORIBONUCLEIC ACIDS INVOLVED IN POSTSURGICAL AND CHRONIC POSTSURGICAL PAIN IN ANIMAL MODELS AND CLINICAL STUDIES. RESULTS: THE INITIAL SEARCH PROVIDED 174 ARTICLES, AND 95 WERE USED. THE AVAILABLE STUDIES TO DATE, MOSTLY IN ANIMAL MODELS, HAVE SHOWN THAT EPIGENETICS CONTRIBUTES TO THE REGULATION OF GENE EXPRESSION IN THE PATHWAYS INVOLVED IN POSTSURGICAL PAIN AND IN MAINTAINING LONG-TERM PAIN. CONCLUSION: RESEARCH ON POSSIBLE EPIGENETIC MECHANISMS INVOLVED IN POSTSURGICAL PAIN AND CHRONIC POSTSURGICAL PAIN IN HUMANS IS SCARCE. IN VIEW OF THE EVIDENCE AVAILABLE IN ANIMAL MODELS, THERE IS A NEED TO EVALUATE EPIGENETIC PAIN MECHANISMS IN THE CONTEXT OF HUMAN AND CLINICAL STUDIES.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
20   108  24 A REVIEW OF THE PROTECTIVE EFFECT OF MELATONIN IN PESTICIDE-INDUCED TOXICITY. PESTICIDES ARE AMONG THE MOST IMPORTANT CHEMICALS USED IN AGRICULTURE SECTOR. HOWEVER, THEIR EXTENSIVE USE HAS POLLUTED THE ENVIRONMENT AND INCREASED HUMAN VULNERABILITY TO VARIOUS CHRONIC DISEASES. PESTICIDE EXPOSURE CAUSES GENETIC AND EPIGENETIC MODIFICATIONS, ENDOCRINE DISRUPTION, MITOCHONDRIAL DYSFUNCTION AND OXIDATIVE STRESS. AREAS COVERED: THIS REVIEW IS BASED ON THE LITERATURE STUDIES CURRENTLY REPORTED ON PESTICIDE-INDUCED TOXICITY AND THE PROTECTIVE ROLE OF MELATONIN. SCIENTIFIC DATABASES SUCH AS PUBMED, SCOPUS AND WEB OF SCIENCE WERE SEARCHED USING KEYWORDS 'PESTICIDE' AND 'MELATONIN' UP TO JANUARY 2016. FULL LENGTH ARTICLES RELATED TO ANIMAL AND HUMAN EXPOSURE WERE RETRIEVED. A TOTAL NUMBER OF 181 RECORDS WERE OBTAINED, AND AFTER EXCLUDING THE DUPLICATES, 97 PAPERS WERE FURTHER SCREENED ON THE BASIS OF RELEVANCE TO THE TOPIC. EXPERT OPINION: MELATONIN AS A BROAD-SPECTRUM ANTIOXIDANT IS ABLE TO PENETRATE CELLULAR COMPARTMENTS SPECIFICALLY THE MITOCHONDRIA. IT IS A POTENT FREE RADICAL SCAVENGER WITH LOW TOXICITY AND DESIRABLE SOLUBILITY IN ORGANIC AND AQUEOUS PHASES. WE ARE OF THE OPINION THAT MELATONIN IS A PROMISING AGENT IN MINIMIZING ORGAN INJURIES INDUCED BY PESTICIDES.	2017
