1   455 162 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
2   108  35 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
3   639  50 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	

4  5882  46 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.

5  6112  52 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
6  2646  38 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
7  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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
8  2510  42 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
9   190  42 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
10  6524  44 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.

11  1151  40 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
12  2715  33 EXERCISE-INDUCED BIOCHEMICAL CHANGES AND THEIR POTENTIAL INFLUENCE ON CANCER: A SCIENTIFIC REVIEW. AIM: TO REVIEW AND DISCUSS THE AVAILABLE INTERNATIONAL LITERATURE REGARDING THE INDIRECT AND DIRECT BIOCHEMICAL MECHANISMS THAT OCCUR AFTER EXERCISE, WHICH COULD POSITIVELY, OR NEGATIVELY, INFLUENCE ONCOGENIC PATHWAYS. METHODS: THE PUBMED, MEDLINE, EMBASE AND COCHRANE LIBRARIES WERE SEARCHED FOR PAPERS UP TO JULY 2016 ADDRESSING BIOCHEMICAL CHANGES AFTER EXERCISE WITH A PARTICULAR REFERENCE TO CANCER. THE THREE AUTHORS INDEPENDENTLY ASSESSED THEIR APPROPRIATENESS FOR INCLUSION IN THIS REVIEW BASED ON THEIR SCIENTIFIC QUALITY AND RELEVANCE. RESULTS: 168 PAPERS WERE SELECTED AND CATEGORISED INTO INDIRECT AND DIRECT BIOCHEMICAL PATHWAYS. THE INDIRECT EFFECTS INCLUDED CHANGES IN VITAMIN D, WEIGHT REDUCTION, SUNLIGHT EXPOSURE AND IMPROVED MOOD. THE DIRECT EFFECTS INCLUDED INSULIN-LIKE GROWTH FACTOR, EPIGENETIC EFFECTS ON GENE EXPRESSION AND DNA REPAIR, VASOACTIVE INTESTINAL PEPTIDE, OXIDATIVE STRESS AND ANTIOXIDANT PATHWAYS, HEAT SHOCK PROTEINS, TESTOSTERONE, IRISIN, IMMUNITY, CHRONIC INFLAMMATION AND PROSTAGLANDINS, ENERGY METABOLISM AND INSULIN RESISTANCE. SUMMARY: EXERCISE IS ONE OF SEVERAL LIFESTYLE FACTORS KNOWN TO LOWER THE RISK OF DEVELOPING CANCER AND IS ASSOCIATED WITH LOWER RELAPSE RATES AND BETTER SURVIVAL. THIS REVIEW HIGHLIGHTS THE NUMEROUS BIOCHEMICAL PROCESSES, WHICH EXPLAIN THESE POTENTIAL ANTICANCER BENEFITS.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
13  2622  42 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
14  2108  45 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
15  1971  32 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  1998  43 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
17  6096  44 THE EFFECTS OF STRESS AND MEDITATION ON THE IMMUNE SYSTEM, HUMAN MICROBIOTA, AND EPIGENETICS. CONTEXT * GLOBALLY, MORE THAN 25% OF INDIVIDUALS ARE AFFECTED BY ANXIETY AND DEPRESSION DISORDERS. MEDITATION IS GAINING POPULARITY IN CLINICAL SETTINGS AND ITS TREATMENT EFFICACY IS BEING STUDIED FOR A WIDE ARRAY OF PSYCHOLOGICAL AND PHYSIOLOGICAL AILMENTS. AN EXPLORATION OF STRESS PHYSIOLOGY IS AN ESSENTIAL PRECURSOR TO DELINEATION OF THE MECHANISMS UNDERLYING THE BENEFICIAL EFFECTS OF MEDITATION PRACTICES. OBJECTIVE * THE REVIEW OUTLINES A MODEL OF INTERCONNECTED PHYSIOLOGICAL PROCESSES THAT MIGHT SUPPORT THE CONTINUED INCLUSION AND EXPANSION OF MEDITATION IN THE TREATMENT OF DIVERSE MEDICAL CONDITIONS AND TO INVESTIGATE THE ROLE THAT GUT MICROBIOTA MAY PLAY IN REALIZING WELL-BEING THROUGH MEDITATION. DESIGN * THE AUTHORS CONDUCTED A SCIENTIFIC LITERATURE DATABASE SEARCH WITH THE GOAL OF REVIEWING THE LINK BETWEEN STRESS MANAGEMENT TECHNIQUES AND HUMAN MICROBIOTA. THEIR GOAL WAS ALSO TO IDENTIFY THE EXTENT OF UNDERLYING EPIGENETIC REACTIONS IN THESE PROCESSES. THE REVIEW WAS COMPLETED IN APPROXIMATELY 2 Y. DATABASES SEARCHED INCLUDED MEDLINE VIA PUBMED AND OVID, PSYCINFO VIA OVID, SPINET, PROQUEST CENTRAL, SAGE RESEARCH METHODS ONLINE, CINAHL PLUS WITH FULL TEXT, SCIENCE DIRECT, SPRINGER LINK, AND WILEY ONLINE LIBRARY. KEYWORDS SEARCHED INCLUDED, BUT WERE NOT LIMITED TO, STRESS, MEDITATION, MINDFULNESS, IMMUNE SYSTEM, HPA AXIS, SYMPATHETIC NERVOUS SYSTEM, PARASYMPATHETIC NERVOUS SYSTEM, MICROBIOTA, MICROBIOME, GUT-BARRIER FUNCTION, LEAKY GUT, VAGUS NERVE, PSYCHONEUROIMMUNOLOGY, EPIGENETIC, AND NF-KAPPAB. SETTING * THE STUDY TOOK PLACE AT NEW YORK UNIVERSITY (NEW YORK, NY, USA), THE UNIVERSITY OF CALIFORNIA, SAN DIEGO (LA JOLLA, CA, USA), AND THE CHOPRA FOUNDATION (CARLSBAD, CA, USA). RESULTS * PSYCHOLOGICAL STRESS TYPICALLY TRIGGERS A FIGHT-OR-FLIGHT RESPONSE, PROMPTING CORTICOTROPIN-RELEASING HORMONE AND CATECHOLAMINE PRODUCTION IN VARIOUS PARTS OF THE BODY, WHICH ULTIMATELY DISTURBS THE MICROBIOTA. IN THE ABSENCE OF STRESS, A HEALTHY MICROBIOTA PRODUCES SHORT-CHAIN FATTY ACIDS THAT EXERT ANTI-INFLAMMATORY AND ANTITUMOR EFFECTS. DURING STRESS, AN ALTERED GUT MICROBIAL POPULATION AFFECTS THE REGULATION OF NEUROTRANSMITTERS MEDIATED BY THE MICROBIOME AND GUT BARRIER FUNCTION. MEDITATION HELPS REGULATE THE STRESS RESPONSE, THEREBY SUPPRESSING CHRONIC INFLAMMATION STATES AND MAINTAINING A HEALTHY GUT-BARRIER FUNCTION. CONCLUSIONS * THE CURRENT RESEARCH TEAM RECOMMENDS THE INTEGRATION OF MEDITATION INTO CONVENTIONAL HEALTH CARE AND WELLNESS MODELS. CONCURRENTLY, STUDIES TO EXPLORE THE EFFECTS OF MEDITATION ON HUMAN MICROBIOTA ARE WARRANTED.	2017	
                                                                                                                                                                                                                                                                                       
18  2951  37 GENETIC AND EPIGENETIC EPIDEMIOLOGY OF CHRONIC WIDESPREAD PAIN. THE ETIOLOGY UNDERLYING CHRONIC WIDESPREAD PAIN (CWP) REMAINS LARGELY UNKNOWN. AN INTEGRATIVE BIOPSYCHOSOCIAL MODEL SEEMS TO YIELD THE MOST PROMISING EXPLANATIONS FOR THE PATHOGENESIS OF THE CONDITION, WITH GENETIC FACTORS ALSO CONTRIBUTING TO DISEASE DEVELOPMENT AND MAINTENANCE. HERE, WE CONDUCTED A SEARCH OF STUDIES INVESTIGATING THE GENETIC AND EPIGENETIC EPIDEMIOLOGY OF CWP THROUGH ELECTRONIC DATABASES INCLUDING WEB OF SCIENCE, MEDLINE, PUBMED, EMBASE, AND GOOGLE SCHOLAR. COMBINATIONS OF KEYWORDS INCLUDING CWP, CHRONIC PAIN, MUSCULOSKELETAL PAIN, GENETICS, EPIGENETICS, GENE, TWINS, SINGLE-NUCLEOTIDE POLYMORPHISM, GENOTYPE, AND ALLELES WERE USED. IN THE END, A TOTAL OF 15 PUBLICATIONS WERE CONSIDERED RELEVANT TO BE INCLUDED IN THIS REVIEW: EIGHT WERE TWIN STUDIES ON CWP, SIX WERE MOLECULAR GENETIC STUDIES ON CWP, AND ONE WAS AN EPIGENETIC STUDY ON CWP. THE FINDINGS SUGGEST GENETIC AND UNIQUE ENVIRONMENTAL FACTORS TO CONTRIBUTE TO CWP. VARIOUS CANDIDATES SUCH AS SEROTONIN-RELATED PATHWAY GENES WERE FOUND TO BE ASSOCIATED WITH CWP AND SOMATOFORM SYMPTOMS. HOWEVER, STUDIES SHOW SOME LIMITATIONS AND NEED REPLICATION. THE PRESENTED RESULTS FOR CWP COULD SERVE AS A TEMPLATE FOR GENETIC STUDIES ON OTHER CHRONIC PAIN CONDITIONS. ULTIMATELY, A MORE IN-DEPTH UNDERSTANDING OF DISEASE MECHANISMS WILL HELP WITH THE DEVELOPMENT OF MORE EFFECTIVE TREATMENT, INFORM NOSOLOGY, AND REDUCE THE STIGMA STILL LINGERING ON THIS DIAGNOSIS.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
19   497  32 ASSOCIATION BETWEEN BMI AND DNA METHYLATION IN BLOOD OR NORMAL ADULT BREAST TISSUE: A SYSTEMATIC REVIEW. BACKGROUND/AIM: SEVERAL STUDIES HAVE INVESTIGATED THE INFLUENCE OF OBESITY ON DNA METHYLATION (DNAM) TO FIND BIOMARKERS ASSOCIATED WITH THE DETECTION OF CHRONIC DISEASES, INCLUDING BREAST CANCER. THE AIM OF THE STUDY WAS TO SYSTEMATICALLY REVIEW STUDIES EXAMINING THE ASSOCIATION OF BODY MASS INDEX (BMI) AND DNAM IN BLOOD OR NORMAL BREAST TISSUE. MATERIALS AND METHODS: THREE SCIENTIFIC LITERATURE DATABASES (PUBMED, EMBASE AND WEB OF SCIENCE) WERE SCREENED UNTIL MAY 2018. RESULTS: TWENTY-FOUR STUDIES WERE INCLUDED ALONG WITH OURS IN WHICH WE INVESTIGATED THIS RELATION IN THE NORMAL BREAST TISSUE OF 40 BREAST CANCER PATIENTS. CONCLUSION: BMI-ASSOCIATED CPG SITES WERE HIGHLY VARIABLE WITH FEW IDENTIFIED IN LESS THAN HALF OF THE STUDIES. NEVERTHELESS, A FEW GENES POTENTIALLY ASSOCIATED WITH BMI WERE HIGHLIGHTED IN BLOOD (CPT1A, ABCG1, SREBF1 AND LGALS3BP) AND IN NORMAL BREAST TISSUE (PTPRN2 AND ABLIM2). THE VARIABILITY OF THE RESULTS COULD BE EXPLAINED BY THE TISSUE AND CELL-SPECIFICITY OF METHYLATION AND DIFFERENCES IN METHODOLOGY.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
20  1165  43 CONTRIBUTION OF DNA METHYLATION TO THE PATHOGENESIS OF SJOGREN'S SYNDROME: A REVIEW. SJOGREN'S SYNDROME (SS) IS A CHRONIC SYSTEMIC DISEASE CHARACTERISED BY SALIVARY AND LACRIMAL GLAND DYSFUNCTION WITH SEVERE IMPLICATIONS FOR THE WELL-BEING OF BEARING INDIVIDUALS. ALTHOUGH ITS ORIGIN HAS NOT YET BEEN FULLY ELUCIDATED, IT IS KNOWN THAT GENETIC, ENVIRONMENTAL, AND EPIGENETIC FACTORS ARE IMPORTANT CONTRIBUTORS TO THE PATHOGENESIS OF THIS SYNDROME. DNA METHYLATION IS A RELEVANT, WIDELY STUDIED EPIGENETIC FACTOR THAT IS POSSIBLY RELATED TO THE ESTABLISHMENT OF SS. THE AIM OF THE PRESENT STUDY WAS TO PERFORM A SYSTEMATIC REVIEW OF THE LITERATURE TO COMPILE STUDIES ON THE CONTRIBUTION OF DNA METHYLATION TO THE PATHOGENESIS OF SS. A LITERATURE SEARCH WAS PERFORMED IN 4 DATABASES (PUBMED, WEB OF SCIENCE, LILACS, AND SCOPUS) USING PREVIOUSLY SELECTED MEDICAL SUBJECT HEADINGS (MESH) DESCRIPTORS, AND ARTICLE SELECTION CONSIDERED OBSERVATIONAL STUDIES ONLY. AFTER A FULL-TEXT READING OF THE SELECTED ARTICLES, 15 STUDIES WERE IN ACCORDANCE WITH THE ELIGIBILITY CRITERIA FOR DATA EXTRACTION. METHYLATION DETECTION APPROACHES INCLUDED GLOBAL METHYLATION, GENOME-WIDE ASSESSMENT OF DIFFERENTIALLY METHYLATED REGIONS, AND SITE-SPECIFIC METHYLATION. FOURTEEN ARTICLES REPORTED ASSOCIATIONS OF DNA METHYLATION PROFILES IN SS PATIENTS, BOTH GLOBALLY AND IN SEVERAL GENES IN SALIVARY GLANDS AND BLOOD CELLS. THUS, DNA METHYLATION MAY CONTRIBUTE TO THE PATHOGENESIS OF SS. THE FINDINGS REINFORCE THE IMPORTANCE OF EPIGENETIC MARKERS IN THE DYNAMICS OF SS AND MAY DIRECT EFFORTS TOWARD THE DEVELOPMENT OF NEW DIAGNOSTIC AND THERAPEUTIC APPROACHES.	2022
