1  6713 184 VISCERAL ADIPOSITY SYNDROME. THE ASSOCIATION OF ANTHROPOMETRIC (WAIST CIRCUMFERENCE) AND HEMODYNAMIC (BLOOD PRESSURE) CHANGES WITH ABNORMALITIES IN GLUCOSE AND LIPID METABOLISM HAS BEEN MOTIVATION FOR A LOT OF DISCUSSIONS IN THE LAST 30 YEARS. NOWADAYS, BLOOD PRESSURE, BODY MASS INDEX/ABDOMINAL CIRCUMFERENCE, GLYCEMIA, TRIGLYCERIDEMIA, AND HDL-CHOLESTEROL CONCENTRATIONS ARE CONSIDERED IN THE DEFINITION OF METABOLIC SYNDROME, REFERRED AS VISCERAL ADIPOSITY SYNDROME (VAS) IN THE PRESENT REVIEW. HOWEVER, MORE THAN 250 YEARS AGO AN ASSOCIATION BETWEEN VISCERAL AND MEDIASTINAL OBESITY WITH HYPERTENSION, GOUT, AND OBSTRUCTIVE APNEA HAD ALREADY BEEN RECOGNIZED. EXPANSION OF VISCERAL ADIPOSE TISSUE SECONDARY TO CHRONIC OVER-CONSUMPTION OF CALORIES STIMULATES THE RECRUITMENT OF MACROPHAGES, WHICH ASSUME AN INFLAMMATORY PHENOTYPE AND PRODUCE CYTOKINES THAT DIRECTLY INTERFERE WITH INSULIN SIGNALING, RESULTING IN INSULIN RESISTANCE. IN TURN, INSULIN RESISTANCE (IR) MANIFESTS ITSELF IN VARIOUS TISSUES, CONTRIBUTING TO THE OVERALL PHENOTYPE OF VAS. FOR EXAMPLE, IN WHITE ADIPOSE TISSUE, IR RESULTS IN LIPOLYSIS, INCREASED FREE FATTY ACIDS RELEASE AND WORSENING OF INFLAMMATION, SINCE FATTY ACIDS CAN BIND TO TOLL-LIKE RECEPTORS. IN THE LIVER, IR RESULTS IN INCREASED HEPATIC GLUCOSE PRODUCTION, CONTRIBUTING TO HYPERGLYCEMIA; IN THE VASCULAR ENDOTHELIUM AND KIDNEY, IR RESULTS IN VASOCONSTRICTION, SODIUM RETENTION AND, CONSEQUENTLY, ARTERIAL HYPERTENSION. OTHER PLAYERS HAVE BEEN RECOGNIZED IN THE DEVELOPMENT OF VAS, SUCH AS GENETIC PREDISPOSITION, EPIGENETIC FACTORS ASSOCIATED WITH EXPOSURE TO AN UNFAVOURABLE INTRAUTERINE ENVIRONMENT AND THE GUT MICROBIOTA. MORE RECENTLY, EXPERIMENTAL AND CLINICAL STUDIES HAVE SHOWN THE AUTONOMIC NERVOUS SYSTEM PARTICIPATES IN MODULATING VISCERAL ADIPOSE TISSUE. THE SYMPATHETIC NERVOUS SYSTEM IS RELATED TO ADIPOSE TISSUE FUNCTION AND DIFFERENTIATION THROUGH BETA1, BETA2, BETA3, ALPHA1, AND ALPHA2 ADRENERGIC RECEPTORS. THE RELATION IS BIDIRECTIONAL: SYMPATHETIC DENERVATION OF ADIPOSE TISSUE BLOCKS LIPOLYSIS TO A VARIETY OF LIPOLYTIC STIMULI AND ADIPOSE TISSUE SEND INPUTS TO THE BRAIN. AN IMBALANCE OF SYMPATHETIC/PARASYMPATHETIC AND ALPHA2 ADRENERGIC/BETA3 RECEPTOR IS RELATED TO VISCERAL ADIPOSE TISSUE STORAGE AND INSULIN SENSITIVITY. THUS, IN ADDITION TO THE WELL-KNOWN FACTORS CLASSICALLY ASSOCIATED WITH VAS, ABNORMAL AUTONOMIC ACTIVITY ALSO EMERGES AS AN IMPORTANT FACTOR REGULATING WHITE ADIPOSE TISSUE, WHICH HIGHLIGHTS COMPLEX ROLE OF ADIPOSE TISSUE IN THE VAS.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
2   190  22 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
3  6418  28 THE TEMPORAL EXPRESSION OF CIRCULATING MICRORNAS AFTER ACUTE EXPERIMENTAL PAIN IN HUMANS. BACKGROUND: MICRORNAS (MIRNAS) CAN MODULATE SEVERAL BIOLOGICAL SYSTEMS, INCLUDING THE PAIN SYSTEM. THIS STUDY AIMED TO EVALUATE THE TEMPORAL EXPRESSION OF CIRCULATING MIRNAS IN THE PLASMA OF HEALTHY VOLUNTEERS AS A MARKER FOR EPIGENETIC CHANGES BEFORE AND AFTER AN ACUTE, EXPERIMENTAL, PAIN PROVOCATION BY INTRAMUSCULAR HYPERTONIC SALINE INJECTION. METHODS: TWENTY VOLUNTEERS WERE RANDOMLY ALLOCATED INTO TWO GROUPS AND RECEIVED EITHER HYPERTONIC (PAIN) OR ISOTONIC (CONTROL) SALINE INJECTION IN THE FIRST DORSAL INTEROSSEOUS MUSCLE OF THEIR DOMINANT HAND. PAIN INTENSITY WAS CONTINUOUSLY RECORDED FOR 20 MINUTES AFTER INJECTION ON A VAS SCALE FROM 0 TO 100 (0 INDICATES NO PAIN AND 100 THE WORST IMAGINABLE PAIN). BLOOD SAMPLES WERE TAKEN AT BASELINE, 30 MINUTES, 3 HOURS, AND 24 HOURS POST-INJECTION, AND PLASMA WAS SEPARATED. MIRNA EXTRACTS WERE USED FOR RNA SEQUENCING WITH THE ILLUMINA NEXTSEQ PLATFORM. MIRNA TRANSCRIPTS WERE COMPARED BETWEEN THE PAIN AND THE NO-PAIN, CONTROL GROUP AT EVERY TIME POINT. SIGNIFICANT DIFFERENCES WERE CONSIDERED WHEN FOLDS WERE >2 AND THE FALSE DISCOVERY RATE WAS P < 0.05. RESULTS: AFTER 30 MINUTES, 4 MIRNAS WERE SIGNIFICANTLY ALTERED IN THE PAIN GROUP COMPARED TO CONTROLS, WHICH INCREASED TO 24 AFTER 3 HOURS AND TO 42 AFTER 24 HOURS FROM BASELINE (P < 0.0001). TWO MIRNAS WERE CONSISTENTLY UPREGULATED THROUGHOUT THE EXPERIMENT. ENRICHMENT ANALYSIS SHOWED SIGNIFICANT MIRNAS INVOLVED IN BRAIN PERCEPTION OF PAIN, BRAIN SIGNALLING AND RESPONSE TO STIMULI. CONCLUSIONS: THIS EXPLORATORY STUDY IS THE FIRST TO REPORT ON THE TEMPORAL EXPRESSION OF CIRCULATING MIRNAS AFTER AN ACUTE, HUMAN EXPERIMENTAL MUSCLE PAIN MODEL. SIGNIFICANCE: THIS EXPLORATORY STUDY EVALUATED THE TEMPORAL PROFILE OF CIRCULATING MIRNAS IN THE PLASMA OF HEALTHY SUBJECTS AFTER ACUTE EXPERIMENTAL PAIN. SEVERAL MIRNAS WERE ALTERED IN SUBJECTS AT THE TIMES OF FOLLOW-UP AFTER THE ACUTE PAIN MODEL WHEN COMPARED TO CONTROLS. MIRNAS PREVIOUSLY ASSOCIATED WITH PAIN PROCESSES WERE ALTERED IN THE PAIN GROUP. OUR RESULTS, BY SHOWING THE FAST AND PROLONGED MODIFICATIONS OF MIRNA ELICITED BY THE ACUTE EXPERIMENTAL PAIN MODEL, ADD NEW PERSPECTIVES TO THE TOPIC OF EPIGENETICS AND PAIN.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
4  5478  26 RESULTS OF A RANDOMIZED STUDY OF 3 SCHEDULES OF LOW-DOSE DECITABINE IN HIGHER-RISK MYELODYSPLASTIC SYNDROME AND CHRONIC MYELOMONOCYTIC LEUKEMIA. EPIGENETIC THERAPY WITH HYPOMETHYLATING DRUGS IS NOW THE STANDARD OF CARE IN MYELODYSPLASTIC SYNDROME (MDS). RESPONSE RATES REMAIN LOW, AND MECHANISM-BASED DOSE OPTIMIZATION HAS NOT BEEN REPORTED. WE INVESTIGATED THE CLINICAL AND PHARMACODYNAMIC RESULTS OF DIFFERENT DOSE SCHEDULES OF DECITABINE. ADULTS WITH ADVANCED MDS OR CHRONIC MYELOMONOCYTIC LEUKEMIA (CMML) WERE RANDOMIZED TO 1 OF 3 DECITABINE SCHEDULES: (1) 20 MG/M2 INTRAVENOUSLY DAILY FOR 5 DAYS; (2) 20 MG/M2 SUBCUTANEOUSLY DAILY FOR 5 DAYS; AND (3) 10 MG/M2 INTRAVENOUSLY DAILY FOR 10 DAYS. RANDOMIZATION FOLLOWED A BAYESIAN ADAPTIVE DESIGN. NINETY-FIVE PATIENTS WERE TREATED (77 WITH MDS, AND 18 WITH CMML). OVERALL, 32 PATIENTS (34%) ACHIEVED A COMPLETE RESPONSE (CR), AND 69 (73%) HAD AN OBJECTIVE RESPONSE BY THE NEW MODIFIED INTERNATIONAL WORKING GROUP CRITERIA. THE 5-DAY INTRAVENOUS SCHEDULE, WHICH HAD THE HIGHEST DOSE-INTENSITY, WAS SELECTED AS OPTIMAL; THE CR RATE IN THAT ARM WAS 39%, COMPARED WITH 21% IN THE 5-DAY SUBCUTANEOUS ARM AND 24% IN THE 10-DAY INTRAVENOUS ARM (P < .05). THE HIGH DOSE-INTENSITY ARM WAS ALSO SUPERIOR AT INDUCING HYPOMETHYLATION AT DAY 5 AND AT ACTIVATING P15 EXPRESSION AT DAYS 12 OR 28 AFTER THERAPY. WE CONCLUDE THAT A LOW-DOSE, DOSE-INTENSITY SCHEDULE OF DECITABINE OPTIMIZES EPIGENETIC MODULATION AND CLINICAL RESPONSES IN MDS.	2007	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
5  3179  24 HAIR CORTISOL AS A HYPOTHALAMIC-PITUITARY-ADRENAL AXIS BIOMARKER IN PREGNANT WOMEN WITH ASTHMA: A RETROSPECTIVE OBSERVATIONAL STUDY. BACKGROUND: CORTISOL IS A HORMONE INVOLVED IN MANY PHYSIOLOGICAL FUNCTIONS INCLUDING FETAL MATURATION AND EPIGENETIC PROGRAMMING DURING PREGNANCY. THIS STUDY AIMED TO USE HAIR CORTISOL AS A BIOMARKER OF CHRONIC INHALED CORTICOSTEROID (ICS) EXPOSURE AND ASSESS THE POTENTIAL EFFECTS OF ASTHMA ON THE HYPOTHALAMIC-PITUITARY-ADRENAL (HPA) AXIS IN PREGNANT WOMEN. WE HYPOTHESIZED THAT PREGNANT WOMEN WITH ASTHMA TREATED WITH ICS WOULD EXHIBIT LOWER HAIR CORTISOL CONCENTRATIONS, INDICATIVE OF ADRENAL SUPPRESSION, COMPARED TO WOMEN WITH ASTHMA NOT USING ICS AND WOMEN WHO DO NOT HAVE ASTHMA. METHODS: WE PERFORMED AN OBSERVATIONAL RETROSPECTIVE COHORT STUDY. HAIR SAMPLES WERE ANALYZED FROM PREGNANT WOMEN WITH ASTHMA, WITH (N = 56) AND WITHOUT (N = 31) ICS TREATMENT, AND PREGNANT WOMEN WITHOUT ASTHMA (N = 31). HAIR SAMPLES WERE SEGMENTED BASED ON THE GROWTH RATE OF 1 CM/MONTH AND ANALYZED BY ENZYME IMMUNOASSAY TO PROVIDE CORTISOL CONCENTRATIONS CORRESPONDING TO PRECONCEPTION, TRIMESTERS 1-3, AND POSTPARTUM. HAIR CORTISOL CONCENTRATIONS WERE COMPARED WITHIN AND AMONG THE GROUPS USING NON-PARAMETRIC STATISTICAL TESTS. RESULTS: HAIR CORTISOL CONCENTRATIONS INCREASED ACROSS TRIMESTERS FOR ALL THREE GROUPS, BUT THIS INCREASE WAS DAMPENED IN WOMEN WITH ASTHMA (P = 0.03 FOR CONTROLS VS. ICS TREATED AND CONTROLS VS. NO ICS). ICS TREATED WOMEN TAKING MORE THAN FIVE DOSES PER WEEK HAD HAIR CORTISOL CONCENTRATIONS 47 % LOWER IN THIRD TRIMESTER THAN CONTROLS. LINEAR REGRESSION OF THE THIRD TRIMESTER HAIR CORTISOL RESULTS IDENTIFIED ASTHMA AS A SIGNIFICANT FACTOR WHEN COMPARING CONSISTENT ICS USE OR ASTHMA AS THE PREDICTOR (F(1, 25) = 9.7, P = 0.005, R(2) ADJ = 0.257). CONCLUSIONS: HAIR CORTISOL SUCCESSFULLY SHOWED THE EXPECTED CHANGE IN CORTISOL OVER THE COURSE OF PREGNANCY AND MAY BE A USEFUL BIOMARKER OF HPA AXIS FUNCTION IN PREGNANT WOMEN WITH ASTHMA. THE POTENTIAL IMPACT OF DECREASED MATERNAL CORTISOL IN WOMEN WITH ASTHMA ON PERINATAL OUTCOMES REMAINS TO BE DETERMINED.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
6  3850  31 IS GENDER A FACTOR AFFECTING LONG-TERM HETEROTOPIC OSSIFICATION INCIDENCE AFTER SINGLE-LEVEL CERVICAL DISC ARTHROPLASTY? BACKGROUND: CERVICAL DISC DISEASES HAVE BEEN TREATED BY CERVICAL DISC ARTHROPLASTY (CDA). NEVERTHELESS, SOME PATIENTS WILL EXPERIENCE A MOBILITY FAILURE IN THEIR CERVICAL PROSTHESES OVER TIME BECAUSE OF HETEROTOPIC OSSIFICATION. THE AIM OF THIS STUDY WAS TO INVESTIGATE THE ROLE OF GENDER IN LONG-TERM OUTCOMES AFTER CDA. METHODS: A RETROSPECTIVE, SINGLE-CENTER STUDY OF PATIENTS WHO UNDERWENT SINGLE-LEVEL CDA WITH A BRYAN CERVICAL DISC PROSTHESIS WAS PERFORMED, INCLUDING A NARRATIVE REVIEW ABOUT GENDER DIFFERENCES IN BOTH STRUCTURAL AND BIOMECHANICAL FEATURES OF THE CERVICAL SPINE. RESULTS: STUDY PATIENTS (14 MEN, 30 WOMEN) HAD AN AVERAGE FOLLOW-UP OF 9.8 +/- 3.2 YEARS. SIGNIFICANT DIFFERENCES EMERGED BETWEEN GENDERS FOR SPECIFIC ITEMS IN NECK DISABILITY INDEX PREOPERATIVE EVALUATION, WITH WOMEN REPORTING WORSE PAIN SCORES (P = 0.05). AFTER STRATIFICATION BY AGE, WE FOUND A HIGHER PREOPERATIVE OVERALL NECK DISABILITY INDEX SCORE FOR FEMALE PATIENTS <36 YEARS OF AGE (P = 0.03). IN AN INTERGENDER, BODY MASS INDEX-SPECIFIC COMPARISON, WE ALSO FOUND A SIGNIFICANT DIFFERENCE IN NECK DISABILITY INDEX PREOPERATIVE SCORE WITH NORMAL-WEIGHT MALE PATIENTS FARING WORSE THAN OVERWEIGHT MALE PATIENTS (P = 0.05). AT A RADIOLOGICAL LEVEL, WE FOUND A TENDENCY TOWARD A HIGHER HETEROTOPIC OSSIFICATION INCIDENCE IN MALE PATIENTS (62% IN MEN, 17% IN WOMEN, P = 0.06). THE FEMALE CERVICAL SPINE HAS DISTINCTIVE FEATURES, INCLUDING BONE STRUCTURE, MUSCULAR ACTION, SOFT TISSUE RESPONSE, AND GENETIC AND EPIGENETIC RESPONSE TO OSTEOARTHRITIS. CONCLUSIONS: THE INCIDENCE OF MOBILITY FAILURE IN OUR SERIES OF SINGLE-LEVEL CDA WAS LOWER IN FEMALE PATIENTS. SEVERAL GENDER-SPECIFIC FACTORS BOTH IN STATIC AND IN DYNAMIC FEATURES MAY PLAY A SIGNIFICANT ROLE IN SPINAL PATHOLOGY AND CDA LONG-TERM RADIOLOGICAL OUTCOME.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
7  5612  29 SAFETY AND ACTIVITY OF RRX-001 IN PATIENTS WITH ADVANCED CANCER: A FIRST-IN-HUMAN, OPEN-LABEL, DOSE-ESCALATION PHASE 1 STUDY. BACKGROUND: EPIGENETIC ALTERATIONS HAVE BEEN STRONGLY ASSOCIATED WITH TUMOUR FORMATION AND RESISTANCE TO CHEMOTHERAPEUTIC DRUGS, AND EPIGENETIC MODIFICATIONS ARE AN ATTRACTIVE TARGET IN CANCER RESEARCH. RRX-001 IS ACTIVATED BY HYPOXIA AND INDUCES THE GENERATION OF REACTIVE OXYGEN AND NITROGEN SPECIES THAT CAN EPIGENETICALLY MODULATE DNA METHYLATION, HISTONE DEACETYLATION, AND LYSINE DEMETHYLATION. THE AIM OF THIS PHASE 1 STUDY WAS TO ASSESS THE SAFETY, TOLERABILITY, AND PHARMACOKINETICS OF RRX-001. METHODS: IN THIS OPEN-LABEL, DOSE-ESCALATION, PHASE 1 STUDY, WE RECRUITED ADULT PATIENTS (AGED >18 YEARS) WITH HISTOLOGICALLY OR CYTOLOGICALLY CONFIRMED DIAGNOSIS OF ADVANCED, MALIGNANT, INCURABLE SOLID TUMOURS FROM UNIVERSITY OF CALIFORNIA AT SAN DIEGO, CA, USA, AND SARAH CANNON RESEARCH INSTITUTE, NASHVILLE, TN, USA. KEY ELIGIBILITY CRITERIA INCLUDED EVALUABLE DISEASE, EASTERN COOPERATIVE GROUP PERFORMANCE STATUS OF 2 OR LESS, AN ESTIMATED LIFE EXPECTANCY OF AT LEAST 12 WEEKS, ADEQUATE LABORATORY PARAMETERS, DISCONTINUATION OF ALL PREVIOUS ANTINEOPLASTIC THERAPIES AT LEAST 6 WEEKS BEFORE INTERVENTION, AND NO RESIDUAL SIDE-EFFECTS FROM PREVIOUS THERAPIES. PATIENTS WERE ASSIGNED TO RECEIVE INTRAVENOUS INFUSIONS OF RRX-001 AT INCREASING DOSES (10 MG/M(2), 16.7 MG/M(2), 24.6 MG/M(2), 33 MG/M(2), 55 MG/M(2), AND 83 MG/M(2)) EITHER ONCE OR TWICE-WEEKLY FOR AT LEAST 4 WEEKS, WITH AT LEAST THREE PATIENTS PER DOSE COHORT AND ALLOWING A 2-WEEK OBSERVATION PERIOD BEFORE DOSE ESCALATION. SAMPLES FOR SAFETY AND PHARMACOKINETICS ANALYSIS, INCLUDING STANDARD CHEMISTRY AND HAEMATOLOGICAL PANELS, WERE TAKEN ON EACH TREATMENT DAY. THE PRIMARY OBJECTIVE WAS TO ASSESS SAFETY, TOLERABILITY, AND DOSE-LIMITING TOXIC EFFECTS OF RRX-001, TO DETERMINE SINGLE-DOSE PHARMACOKINETICS, AND TO IDENTIFY A RECOMMENDED DOSE FOR PHASE 2 TRIALS. ALL ANALYSES WERE DONE PER PROTOCOL. ACCRUAL IS COMPLETE AND FOLLOW-UP IS STILL ON-GOING. THIS TRIAL IS REGISTERED WITH CLINICALTRIALS.GOV, NUMBER NCT01359982. FINDINGS: BETWEEN OCT 10, 2011, AND MARCH 18, 2013, WE ENROLLED 25 PATIENTS AND TREATED SIX PATIENTS IN THE 10 MG/M(2) COHORT, THREE PATIENTS IN THE 16.7 MG/M(2) COHORT, THREE PATIENTS IN THE 24.6 MG/M(2) COHORT, FOUR PATIENTS IN THE 33 MG/M(2) COHORT, THREE PATIENTS IN THE 55 MG/M(2), AND SIX PATIENTS IN THE 83 MG/M(2) COHORT. PAIN AT THE INJECTION SITE, MOSTLY GRADE 1 AND GRADE 2, WAS THE MOST COMMON ADVERSE EVENT RELATED TO TREATMENT, EXPERIENCED BY 21 (84%) PATIENTS. OTHER COMMON DRUG-RELATED ADVERSE EVENTS INCLUDED ARM SWELLING OR OEDEMA (EIGHT [32%] PATIENTS), AND VEIN HARDENING (SEVEN [28%] PATIENTS). NO DOSE-LIMITING TOXICITIES WERE OBSERVED. TIME CONSTRAINTS RELATED TO MANAGEMENT OF INFUSION PAIN FROM RRX-001 RESULTED IN A MAXIMALLY FEASIBLE DOSE OF 83 MG/M(2). OF THE 21 EVALUABLE PATIENTS, ONE (5%) PATIENT HAD A PARTIAL RESPONSE, 14 (67%) PATIENTS HAD STABLE DISEASE, AND SIX (29%) PATIENTS HAD PROGRESSIVE DISEASE; ALL RESPONSES WERE ACROSS A VARIETY OF TUMOUR TYPES. FOUR PATIENTS WHO HAD RECEIVED RRX-001 WERE SUBSEQUENTLY RECHALLENGED WITH A TREATMENT THAT THEY HAD BECOME REFRACTORY TO; ALL FOUR RESPONDED TO THE RECHALLENGE. INTERPRETATION: RRX-001 IS A WELL-TOLERATED NOVEL COMPOUND WITHOUT CLINICALLY SIGNIFICANT TOXIC EFFECTS AT THE TESTED DOSES. PRELIMINARY EVIDENCE OF ACTIVITY IS PROMISING AND, ON THE BASIS OF ALL FINDINGS, A DOSE OF 16.7 MG/M(2) WAS RECOMMENDED AS THE TARGETED DOSE FOR PHASE 2 TRIALS.

MORE SPECIFICALLY, CLIMATE CHANGE HAS RESULTED IN MORE FREQUENT HEAT STRESS EVENTS THAT INCREASE THE INCIDENCE OF CHRONIC BACTERIAL INFECTIONS BY INDUCING CONDITIONS LIKE LEAKY GUT SYNDROME, WHEREBY THE INTEGRITY OF THE INTESTINAL EPITHELIUM IS COMPROMISED ALLOWING FOR LUMINAL BACTERIAL LIPOPOLYSACCHARIDE (LPS) ENDOTOXIN TO INFILTRATE THE HOST'S BLOODSTREAM RESULTING IN ACUTE OR CHRONIC SYSTEMIC STIMULATION OF THE INNATE IMMUNE SYSTEM. REPEATED EXPOSURE TO LPS OVER A SHORT PERIOD OF TIME IS REPORTED TO INDUCE IMMUNOTOLERANCE WITHIN THE HOST. THIS LPS TOLERANCE IS AN ESSENTIAL IMMUNOHOMEOSTATIC RESPONSE THAT CAN PROTECT AGAINST OVER ACTIVATION OF THE INFLAMMATORY RESPONSE DURING SUBSEQUENT EXPOSURE TO LPS. IN THE PRESENT STUDY, HOLSTEIN CALVES (N = 20) WERE INITIALLY STRESS CHALLENGED WITH EITHER SALINE, OR 100, 200 OR 400 NG/KG OF LPS ADMINISTERED INTRAMUSCULAR, AND AGAIN RE-CHALLENGED WITH 200 NG/KG OF LPS 2-WEEKS LATER. SERUM WAS COLLECTED EVERY 2 HR FOR 6 HR TO PROFILE CHANGES IN CIRCULATORY STRESS BIOMARKERS AFTER THE REPEATED LPS EXPOSURES. HEIFERS THAT WERE INITIALLY CHALLENGED WITH 100, 200 AND 400 NG/KG OF LPS DEMONSTRATED SIGNIFICANTLY ATTENUATED CORTISOL RESPONSES IN THE SECOND CHALLENGE (P < 0.01, 0.01 AND 0.05, RESPECTIVELY), WHEREAS CONTROL ANIMALS WHO PREVIOUSLY RECEIVED SALINE DEMONSTRATED A STRONG CORTISOL RESPONSE AT 2 HR AFTER RECEIVING 200 NG/KG OF LPS (P < 0.05). THE CYTOKINE/CHEMOKINE (IL-6, CCL2, CCL3 AND CCL4) RESPONSES WERE ALSO ATTENUATED DURING THE LPS RECHALLENGE (P < 0.05). FINALLY, MICRORNA EXPRESSION PROFILES WERE DETERMINED TO ASSESS THE EPIGENETIC RESPONSE TO REPEATED LPS EXPOSURE. INTERESTINGLY, MIR-31 AND MIR-223 WERE DOWNREGULATED IN RESPONSE TO THE SECOND LPS CHALLENGE. THE PRESENT STUDY DEMONSTRATES THE DYNAMIC NATURE OF THE STRESS RESPONSE IN DAIRY CATTLE AS IT RELATES TO THE DEVELOPMENT OF LPS TOLERANCE. UNDERSTANDING THE ROLES OF VARIOUS STRESS BIOMARKERS IN THE CONTEXT OF INNATE IMMUNE CELL TOLERANCE IS ESSENTIAL FOR EVALUATING THEIR IMPACT ON IMMUNE SYSTEM HOMEOSTASIS.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
9   983  26 CHRONIC PROSTATITIS AFFECTS MALE REPRODUCTIVE HEALTH AND IS ASSOCIATED WITH SYSTEMIC AND LOCAL EPIGENETIC INACTIVATION OF C-X-C MOTIF CHEMOKINE 12 RECEPTOR C-X-C CHEMOKINE RECEPTOR TYPE 4. BACKGROUND/AIMS/OBJECTIVES: CHRONIC PROSTATITIS/CHRONIC PELVIC PAIN SYNDROME (CP/CPPS) HAS DETRIMENTAL EFFECTS ON THE QUALITY OF LIFE INCLUDING THE ASPECT OF SEXUAL DYSFUNCTION. THE AIM OF THE STUDY WAS TO IDENTIFY IF THERE WAS AN ADVERSE EFFECT ON THE MALE GENITAL COMPARTMENT AND IF THERE ARE SYSTEMIC OR COMPARTMENT-SPECIFIC LOCAL SIGNALS FOR EPIGENETIC DYSREGULATION OF INFLAMMATORY FACTORS IN CP/CPPS PATIENTS. METHODS: ONE HUNDRED FIVE NIH IIIB CP/CPPS PATIENTS AND 41 HEALTHY MEN WERE RECRUITED AND UNDERWENT INVESTIGATIONS OF URINES, SEMEN AND BLOOD. PROMOTER METHYLATION AND EXPRESSION OF THE CHEMOKINE C-X-C MOTIF CHEMOKINE 12 AND ITS RECEPTOR C-X-C CHEMOKINE RECEPTOR TYPE 4 (CXCR4) (INVOLVED IN THE RECRUITMENT OF MAST CELLS) WERE ANALYZED IN PROSTATE EPITHELIAL CELL LINES AND IN HEALTHY VOLUNTEERS' AND PATIENTS' BLOOD, EJACULATE CELL PELLETS, AND SEPARATED EJACULATE FRACTIONS (SPERM AND SEMINAL SOMATIC CELLS). RESULTS: INDEPENDENTLY FROM AGE, CP/CPPS NIH IIIB WAS ASSOCIATED WITH SIGNIFICANT IMPAIRMENT OF SPERM MOTILITY, MORPHOLOGY AND SEMEN PH (P < 0.001). PATIENTS OLDER THAN 33 YEARS SHOWED SIGNIFICANTLY INCREASED SEMINAL INTERLEUKIN-8 AND SERUM PROSTATE SPECIFIC ANTIGEN VALUES. IN PATIENTS, THE CXCR4 MRNA-EXPRESSION WAS SIGNIFICANTLY DECREASED IN WHOLE BLOOD AND EJACULATE CELL PELLETS DUE TO PROMOTER HYPERMETHYLATION. ANALYSES ON SEPARATED FRACTIONS OF SPERM AND SEMINAL SOMATIC CELLS REVEALED THAT SPERM DNA WAS UNAFFECTED, WHEREAS SOMATIC CELL DNA WAS DIFFERENTIALLY METHYLATED. CONCLUSIONS: NIH IIIB CP/CPPS HAS NEGATIVE EFFECTS ON SURROGATE PARAMETERS OF MALE FERTILITY AND IS ASSOCIATED SIGNIFICANTLY WITH SYSTEMIC AND LOCAL EPIGENETIC INACTIVATION OF CXCR4.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
10  3785  16 INTERGENERATIONAL EFFECTS OF PRE-PREGNANCY CHRONIC LIPOPOLYSACCHARIDE FROM PORPHYROMONAS GINGIVALIS ON THE LEARNING, MEMORY AND SEIZURE SUSCEPTIBILITY OF OFFSPRING. OBJECTIVE: THE AIM OF THIS STUDY WAS TO INVESTIGATE THE EFFECTS OF PRE-PREGNANCY CHRONIC EXPOSURE TO PORPHYROMONAS GINGIVALIS LPS (PG LPS) ON THE LEARNING, MEMORY, AND SEIZURE SUSCEPTIBILITY OF THE OFFSPRING. DESIGN: TO ACHIEVE PERIODONTITIS, PG LPS (5 MUG/KG) WAS INJECTED INTO THE GINGIVAL OF FIVE FEMALE RATS EVERY 48 H FOR THREE WEEKS. FIVE CONTROL FEMALE RATS RECEIVED SALINE (0.9 %) AND FIVE FEMALE WERE KEPT INTACT. THE CONCENTRATIONS OF TNF-ALPHA AND IL-6 WERE MEASURED IN THE BLOOD SAMPLES. ONE WEEK AFTER THE FINAL INJECTION, FEMALES WERE MATED WITH INTACT MALES. FOLLOWING BIRTH AND WEANING, TWO MALE AND TWO FEMALE OFFSPRING WERE RANDOMLY SELECTED FROM EACH MOTHER, AND NEW GROUPS OF MALE AND FEMALE OFFSPRING WERE DEFINED FOR BEHAVIORAL ASSESSMENTS. MORRIS WATER MAZE WAS USED TO EVALUATE SPATIAL MEMORY, SHUTTLE BOX WAS USED TO INVESTIGATE AVOIDANCE MEMORY AND A PENTYLENETETRAZOLE-INDUCED SEIZURE WAS USED TO EVALUATE SEIZURE SUSCEPTIBILITY IN THE OFFSPRING. RESULTS: SPATIAL LEARNING AND AVOIDANCE MEMORY SIGNIFICANTLY DECREASED IN BOTH MALE AND FEMALE OFFSPRING OF PG LPS-EXPOSED FEMALE RATS, COMPARED TO THE CONTROL OFFSPRING. LATENCY TO REACH SEIZURE STAGES 1 AND 2 SIGNIFICANTLY INCREASED IN THE MALE OFFSPRING, BUT NOT THE FEMALE OFFSPRING OF PG LPS-EXPOSED FEMALE, COMPARED TO THE CONTROL OFFSPRING. HOWEVER, NO SIGNIFICANT DIFFERENCE WAS FOUND IN LATENCY TO REACH STAGES 3-5. CONCLUSION: PRE-PREGNANCY EXPOSURE TO PG LPS COULD AFFECT SOME BEHAVIORAL FUNCTIONS IN BOTH MALE AND FEMALE OFFSPRING INTERGENERATIONALLY.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
11  5085  27 PILOT STUDY OF ABSOLUTE TELOMERE LENGTHS IN PRETERM INFANTS. BACKGROUND: ANNUALLY, APPROXIMATELY 15 MILLION BABIES ARE BORN PRETERM (<37 WEEKS GESTATIONAL AGE) GLOBALLY. IN THE NEONATAL INTENSIVE CARE UNIT (NICU) ENVIRONMENT, INFANTS ARE EXPOSED TO REPEATED STRESSFUL OR PAINFUL PROCEDURES AS PART OF ROUTINE LIFESAVING CARE. THESE PROCEDURES HAVE BEEN ASSOCIATED WITH EPIGENETIC ALTERATIONS THAT MAY LEAD TO AN INCREASED RISK OF NEURODEVELOPMENTAL DISORDERS. TELOMERE LENGTH HAS BEEN NEGATIVELY ASSOCIATED WITH ADVERSE LIFE EXPERIENCES IN STUDIES OF ADULTS. OBJECTIVES: THIS PILOT STUDY AIMED TO DESCRIBE TELOMERE LENGTH IN A SAMPLE OF PRETERM INFANTS AT NICU DISCHARGE AND EXAMINE ANY ASSOCIATIONS WITH PAIN, FEEDING METHOD, AND NEURODEVELOPMENT. METHODS: THIS DESCRIPTIVE PILOT STUDY SAMPLE INCLUDES BASELINE ABSOLUTE TELOMERE LENGTH (ATL) OF 36 PRETERM INFANTS IMMEDIATELY PRIOR TO DISCHARGE. QUANTITATIVE POLYMERASE CHAIN REACTION WAS USED TO DETERMINE ATL. INFANT DEMOGRAPHICS, PAIN/STRESS, TYPE OF FEEDING, ANTIBIOTIC USE, NEURODEVELOPMENT, AND BUCCAL SWAB DATA WERE COLLECTED. DESCRIPTIVE DATA ANALYSIS WAS USED TO DESCRIBE THE TELOMERE LENGTH USING GRAPHS. RESULTS: AMONG OUR PRETERM INFANT SAMPLES, THE MEAN ATL WAS FAR GREATER THAN THE AVERAGE ADULT TELOMERE LENGTH. ALTHOUGH NO SIGNIFICANT ASSOCIATIONS WERE FOUND BETWEEN ATL AND PAIN, FEEDING METHOD, AND NEURODEVELOPMENT, A TREND BETWEEN SEX WAS NOTED WHERE MALE TELOMERE LENGTHS WERE SHORTER THAN FEMALES AS THEY AGED. DISCUSSION: THIS IS ONE OF FEW STUDIES TO EVALUATE PRETERM INFANT TELOMERE LENGTH. ALTHOUGH OTHER RESEARCHERS HAVE USED RELATIVE TELOMERE LENGTH, WE USED THE MORE ACCURATE ATL. WE FOUND NONSIGNIFICANT SHORTER TELOMERE LENGTHS AMONG MALES. ADDITIONAL LARGE-SCALE, LONGITUDINAL STUDIES ARE NEEDED TO BETTER IDENTIFY THE PREDICTORS OF TELOMERE LENGTH AT THE TIME OF DISCHARGE FROM NICU.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
12   448  24 APABETALONE MEDIATED EPIGENETIC MODULATION IS ASSOCIATED WITH FAVORABLE KIDNEY FUNCTION AND ALKALINE PHOSPHATASE PROFILE IN PATIENTS WITH CHRONIC KIDNEY DISEASE. BACKGROUND/AIMS: THE ASSOCIATION BETWEEN SERUM ALKALINE PHOSPHATASE (ALP) WITH ADVERSE CARDIOVASCULAR OUTCOMES, IN CHRONIC KIDNEY DISEASE (CKD) PATIENTS HAS PREVIOUSLY BEEN REPORTED AND MAY BE A RESULT OF INCREASED VASCULAR CALCIFICATION AND INFLAMMATION. HERE WE REPORT, FOR THE FIRST TIME, THE EFFECTS OF PHARMACOLOGIC EPIGENETIC MODULATION ON LEVELS OF ALP AND KIDNEY FUNCTION VIA A NOVEL ORAL SMALL MOLECULE BET INHIBITOR, APABETALONE, IN CKD PATIENTS. METHODS: A POST-HOC ANALYSIS EVALUATED PATIENTS WITH ESTIMATED GLOMERULAR FILTRATION RATE (EGFR) <60 ML/MIN/1.73M2, WHO PARTICIPATED IN THE APABETALONE PHASE 2 RANDOMIZED CONTROLLED TRIALS (SUSTAIN AND ASSURE). 48 CKD SUBJECTS WITH A HISTORY OF CARDIOVASCULAR DISEASE (CVD) WERE TREATED WITH 100MG TWICE-DAILY OF 24 AND 26 WEEKS OF APABETALONE OR PLACEBO. ALP AND EGFR WERE MEASURED PRIOR TO RANDOMIZATION AND AT FINAL VISITS. RESULTS: PATIENTS WHO RECEIVED APABETALONE (N=35) VERSUS PLACEBO (N=13) OVER 6 MONTHS SHOWED SIGNIFICANTLY (P=0.02) LOWERED SERUM ALP -14.0% (P<0.0001 VERSUS BASELINE) VERSUS -6.3% (P=0.9 VERSUS BASELINE). THE EGFR IN THE APABETALONE GROUP INCREASED BY 3.4% (1.7 ML/MIN/1.73 M2) (P=0.04 VERSUS BASELINE) AND DECREASED BY 5.8% (2.9 ML/MIN/1.73 M2) (P=0.6 VERSUS BASELINE) IN THE PLACEBO GROUP. APABETALONE WAS WELL TOLERATED. CONCLUSION: A POST-HOC ANALYSIS OF CKD SUBJECTS FROM THE SUSTAIN AND ASSURE RANDOMIZED CONTROLLED TRIALS DEMONSTRATED FAVORABLE EFFECTS OF APABETALONE ON ALP AND EGFR, AND GENERATED THE HYPOTHESIS THAT EPIGENETIC MODULATION BY BET INHIBITION MAY POTENTIALLY OFFER A NOVEL THERAPEUTIC STRATEGY TO TREAT CVD AND PROGRESSIVE KIDNEY FUNCTION LOSS IN CKD PATIENTS. THIS IS BEING EXAMINED IN THE PHASE III TRIAL BETONMACE.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
13  1030  42 CIRCULATING PLASMA MICRORNAS DYSREGULATION AND METABOLIC ENDOTOXEMIA INDUCED BY A HIGH-FAT HIGH-SATURATED DIET. HIGH-FAT DIET INCREASE TWO TO THREE TIMES THE PLASMA LIPOPOLYSACCHARIDE (LPS) LEVELS AND INDUCE SUBCLINICAL INFLAMMATION. DIET CAN MODIFY GENE EXPRESSION DUE TO EPIGENETIC PROCESSES RELATED TO MICRORNAS (MIRNAS). MICRORNAS (MIRNAS) PLAY IMPORTANT ROLE IN THE POST-TRANSCRIPTIONAL MECHANISMS INVOLVED IN REGULATION OF EXPRESSION OF GENES RELATED TO THE INFLAMMATORY RESPONSE. ALSO, DIET CAN INDIRECTLY INDUCE POST-TRANSCRIPTIONAL REGULATION OF GENE EXPRESSION BY MIRNAS, WHICH MAY AFFECT THE RISK FOR THE DEVELOPMENT OF CHRONIC DISEASES. OBJECTIVE: THIS STUDY INVESTIGATED THE EFFECT OF HIGH-FAT HIGH-SATURATED MEAL INGESTION ON PLASMA MIRNA EXPRESSION AND LPS LEVELS DURING THE POSTPRANDIAL PERIOD IN HEALTHY WOMEN. METHODS: AN INTERVENTIONAL STUDY WAS CARRIED OUT IN WHICH A HIGH-FAT BREAKFAST (1067.45 KCAL), COMPOSED MAINLY OF SATURATED FATTY ACIDS (56 G), AND 500 ML OF WATER, WAS OFFERED. BLOOD SAMPLES WERE COLLECTED AT BASELINE AND 1, 3 AND 5 H AFTER MEAL INTAKE. THE STUDIED POPULATION CONSISTED OF HEALTHY WOMEN (N = 11), AGED BETWEEN 20 AND 40 YEARS, AND BODY MASS INDEX (BMI) BETWEEN 18.5 AND 25 KG/M(2). PLASMA LEVELS OF LIPID PROFILE, CYTOKINES, ADHESION MOLECULES, AND LPS WERE MEASURED AT THE 3 TIME POINTS. A PROFILE OF 752 HUMAN PLASMA MIRNA EXPRESSION WAS ANALYZED BY REAL-TIME PCR ASSAY. THESE ANALYZES WERE PERFORMED FOR ALL BLOOD COLLECTION TIME-POINTS. RESULTS: EXPRESSION PROFILE ANALYSIS REVEALED 33 DIFFERENTIALLY EXPRESSED PLASMA CIRCULATING MIRNAS COMPARED TO THAT OF THE CONTROL GROUP. MIR-145-5P AND MIR-200 WERE DIFFERENTIALLY MODULATED IN ALL TIME-POINTS POST MEAL CONSUMPTION. IN ADDITION, THERE WAS A SIGNIFICANT INCREASE IN PLASMA LPS, TRIGLYCERIDES, MYRISTIC AND PALMITIC SATURATED FATTY ACIDS LEVELS AT THE 3 TIME-POINTS IN COMPARISON WITH THE CONTROL BASAL LEVELS. WE ALSO OBSERVED INCREASED LEVELS OF THE PLASMA TUMOR NECROSIS FACTOR ALPHA (TNF-ALPHA) CYTOKINE AND THE VASCULAR CELL ADHESION MOLECULE 1 (VCAM-1) LEVELS AFTER 5 H POST MEAL INGESTION. CONCLUSION: INGESTION OF HIGH-FAT HIGH-SATURATED MEAL WAS ABLE TO INDUCE METABOLIC ENDOTOXEMIA AND INCREASE THE EXPRESSION OF PRO-INFLAMMATORY MOLECULES SUCH AS TNF-ALPHA AND VCAM-1, AS WELL AS MODULATING CIRCULATING MIRNAS POSSIBLY CONTROLLING INFLAMMATORY AND LIPID METABOLISM PROTEINS AT THE POSTPRANDIAL PERIOD.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
14  1785  19 EFFECT OF APABETALONE ON CARDIOVASCULAR EVENTS IN DIABETES, CKD, AND RECENT ACUTE CORONARY SYNDROME: RESULTS FROM THE BETONMACE RANDOMIZED CONTROLLED TRIAL. BACKGROUND AND OBJECTIVES: CKD AND TYPE 2 DIABETES MELLITUS INTERACT TO INCREASE THE RISK OF MAJOR ADVERSE CARDIOVASCULAR EVENTS (I.E., CARDIOVASCULAR DEATH, NONFATAL MYOCARDIAL INFARCTION, OR STROKE) AND CONGESTIVE HEART FAILURE. A MALADAPTIVE EPIGENETIC RESPONSE MAY BE A CARDIOVASCULAR RISK DRIVER AND AMENABLE TO MODIFICATION WITH APABETALONE, A SELECTIVE MODULATOR OF THE BROMODOMAIN AND EXTRATERMINAL DOMAIN TRANSCRIPTION SYSTEM. WE EXAMINED THIS QUESTION IN A PRESPECIFIED ANALYSIS OF BETONMACE, A PHASE 3 TRIAL. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: BETONMACE WAS AN EVENT-DRIVEN, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED TRIAL COMPARING EFFECTS OF APABETALONE VERSUS PLACEBO ON MAJOR ADVERSE CARDIOVASCULAR EVENTS AND HEART FAILURE HOSPITALIZATIONS IN 2425 PARTICIPANTS WITH TYPE 2 DIABETES AND A RECENT ACUTE CORONARY SYNDROME, INCLUDING 288 PARTICIPANTS WITH CKD WITH EGFR <60 ML/MIN PER 1.73 M(2) AT BASELINE. THE PRIMARY END POINT IN BETONMACE WAS THE TIME TO THE FIRST MAJOR ADVERSE CARDIOVASCULAR EVENT, WITH A SECONDARY END POINT OF TIME TO HOSPITALIZATION FOR HEART FAILURE. RESULTS: MEDIAN FOLLOW-UP WAS 27 MONTHS (INTERQUARTILE RANGE, 20-32 MONTHS). IN PARTICIPANTS WITH CKD, APABETALONE COMPARED WITH PLACEBO WAS ASSOCIATED WITH FEWER MAJOR ADVERSE CARDIOVASCULAR EVENTS (13 EVENTS IN 124 PATIENTS [11%] VERSUS 35 EVENTS IN 164 PATIENTS [21%]; HAZARD RATIO, 0.50; 95% CONFIDENCE INTERVAL, 0.26 TO 0.96) AND FEWER HEART FAILURE-RELATED HOSPITALIZATIONS (THREE HOSPITALIZATIONS IN 124 PATIENTS [3%] VERSUS 14 HOSPITALIZATIONS IN 164 PATIENTS [9%]; HAZARD RATIO, 0.48; 95% CONFIDENCE INTERVAL, 0.26 TO 0.86). IN THE NON-CKD GROUP, THE CORRESPONDING HAZARD RATIO VALUES WERE 0.96 (95% CONFIDENCE INTERVAL, 0.74 TO 1.24) FOR MAJOR ADVERSE CARDIOVASCULAR EVENTS, AND 0.76 (95% CONFIDENCE INTERVAL, 0.46 TO 1.27) FOR HEART FAILURE-RELATED HOSPITALIZATION. INTERACTION OF CKD ON TREATMENT EFFECT WAS P=0.03 FOR MAJOR ADVERSE CARDIOVASCULAR EVENTS, AND P=0.12 FOR HEART FAILURE-RELATED HOSPITALIZATION. PARTICIPANTS WITH CKD SHOWED SIMILAR NUMBERS OF ADVERSE EVENTS, REGARDLESS OF RANDOMIZATION TO APABETALONE OR PLACEBO (119 [73%] VERSUS 88 [71%] PATIENTS), AND THERE WERE FEWER SERIOUS ADVERSE EVENTS (29% VERSUS 43%; P=0.02) IN THE APABETALONE GROUP. CONCLUSIONS: APABETALONE MAY REDUCE THE INCIDENCE OF MAJOR ADVERSE CARDIOVASCULAR EVENTS IN PATIENTS WITH CKD AND TYPE 2 DIABETES WHO HAVE A HIGH BURDEN OF CARDIOVASCULAR DISEASE.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
15  4504  25 MOTHER'S PRE-PREGNANCY BMI AND PLACENTAL CANDIDATE MIRNAS: FINDINGS FROM THE ENVIRONAGE BIRTH COHORT. THERE IS INCREASING EVIDENCE THAT THE PREDISPOSITION FOR DEVELOPMENT OF CHRONIC DISEASES ARISES AT THE EARLIEST TIMES OF LIFE. IN THIS CONTEXT, MATERNAL PRE-PREGNANCY WEIGHT MIGHT MODIFY FETAL METABOLISM AND THE CHILD'S PREDISPOSITION TO DEVELOP DISEASE LATER IN LIFE. THE AIM OF THIS STUDY IS TO INVESTIGATE THE ASSOCIATION BETWEEN MATERNAL PRE-PREGNANCY BODY MASS INDEX (BMI) AND MIRNA ALTERATIONS IN PLACENTAL TISSUE AT BIRTH. IN 211 MOTHER-NEWBORN PAIRS FROM THE ENVIRONAGE BIRTH COHORT, WE ASSESSED PLACENTAL EXPRESSION OF SEVEN MIRNAS IMPORTANT IN CRUCIAL CELLULAR PROCESSES IMPLICATED IN ADIPOGENESIS AND/OR OBESITY. MULTIPLE LINEAR REGRESSION MODELS WERE USED TO ADDRESS THE ASSOCIATIONS BETWEEN PRE-PREGNANCY BMI AND PLACENTAL CANDIDATE MIRNA EXPRESSION. MATERNAL PRE-PREGNANCY BMI AVERAGED (+/-SD) 23.9 (+/-4.1) KG/M(2). IN NEWBORN GIRLS (NOT IN BOYS) PLACENTAL MIR-20A, MIR-34A AND MIR-222 EXPRESSION WAS LOWER WITH HIGHER MATERNAL PRE-PREGNANCY BMI. IN ADDITION, THE ASSOCIATION BETWEEN MATERNAL PRE-PREGNANCY BMI AND PLACENTAL EXPRESSION OF THESE MIRNAS IN GIRLS WAS MODIFIED BY GESTATIONAL WEIGHT GAIN. THE LOWER EXPRESSION OF THESE MIRNAS IN PLACENTA IN ASSOCIATION WITH PRE-PREGNANCY BMI, WAS ONLY EVIDENT IN MOTHERS WITH LOW WEIGHT GAIN (<14 KG). THE PLACENTAL EXPRESSION OF MIR-20A, MIR-34A, MIR-146A, MIR-210 AND MIR-222 MAY PROVIDE A SEX-SPECIFIC BASIS FOR EPIGENETIC EFFECTS OF PRE-PREGNANCY BMI.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
16  1292  32 DECREASED BLOOD PRESSURE IS RELATED TO CHANGES IN NF-KB PROMOTER METHYLATION LEVELS AFTER BARIATRIC SURGERY. BACKGROUND: OBESITY IS CHARACTERIZED BY A CHRONIC, LOW-GRADE INFLAMMATION, AND BARIATRIC SURGERY IS PROPOSED AS AN EFFECTIVE TREATMENT FOR REDUCING THE OBESITY-RELATED CO-MORBIDITIES. EPIGENETIC MODIFICATIONS COULD BE INVOLVED IN THE METABOLIC IMPROVEMENT AFTER SURGERY. OBJECTIVE: THE MAIN AIM OF THIS STUDY WAS TO EVALUATE WHETHER DNA METHYLATION PATTERN FROM GENES RELATED TO INFLAMMATION AND INSULIN RESPONSE IS ASSOCIATED WITH THE METABOLIC IMPROVEMENT AFTER BARIATRIC SURGERY IN MORBIDLY OBESE PATIENTS AND IF THESE CHANGES DEPEND ON THE SURGICAL PROCEDURE. SETTING: UNIVERSITY HOSPITAL, SPAIN. METHODS: WE STUDIED 60 SEVERELY OBESE PATIENTS; 31 UNDERWENT ROUX-EN-Y GASTRIC BYPASS AND 29 UNDERWENT LAPAROSCOPIC SLEEVE GASTRECTOMY. ALL PATIENTS WERE EXAMINED BEFORE AND AT 6 MONTHS AFTER BARIATRIC SURGERY. DNA METHYLATION PROFILE OF GENES RELATED TO THE INFLAMMATORY RESPONSE AND INSULIN SENSITIVITY WAS MEASURED BY PYROSEQUENCING. RESULTS: THE PROMOTER METHYLATION LEVELS OF THE NFKB1 GENE WERE INCREASED SIGNIFICANTLY AFTER SURGERY (2.16 +/- .9 VERSUS 2.8 +/- 1.03). THE DECREASE IN BLOOD PRESSURE, BOTH SYSTOLIC AND DIASTOLIC, AFTER SURGERY WAS SIGNIFICANTLY ASSOCIATED WITH THE CHANGES IN THE PROMOTER METHYLATION LEVELS OF THE NFKB1 GENE (BETA = -.513, P = .003 AND BETA = -.543, P = .004, RESPECTIVELY). A DECREASE IN INFLAMMATION STATUS, MEASURED BY HIGH SENSITIVITY C-REACTIVE PROTEIN VALUES, WAS ASSOCIATED WITH CHANGES IN SLC19A1 METHYLATION LEVELS. CONCLUSION: OUR STUDY SHOWS FOR THE FIRST TIME AN ASSOCIATION BETWEEN NFKB1 METHYLATION LEVELS AND BLOOD PRESSURE AFTER BARIATRIC SURGERY, HIGHLIGHTING THE POSSIBLE FUNCTION OF THIS GENE IN THE REGULATION OF ARTERIAL PRESSURE. REGARDING SLC19A1, THIS GENE COULD POSITION AS A POTENTIAL TARGET LINKING INFLAMMATION AND INSULIN RESISTANCE.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
17  5129  36 POSTOPERATIVE PAIN AND ANALGESIA: IS THERE A GENETIC BASIS TO THE OPIOID CRISIS? BACKGROUND: MULTIPLE FACTORS HAVE BEEN IMPLICATED IN DETERMINING WHY CERTAIN PATIENTS HAVE INCREASED POSTOPERATIVE PAIN, WITH THE POTENTIAL TO DEVELOP CHRONIC PAIN. THE PURPOSE OF THIS STUDY WAS TO: 1) IDENTIFY AND DESCRIBE GENES THAT AFFECT POSTOPERATIVE PAIN PERCEPTION AND CONTROL; 2) ADDRESS MODIFIABLE RISK FACTORS THAT RESULT IN EPIGENETIC ALTERED RESPONSES TO PAIN; AND 3) CHARACTERIZE DIFFERENCES IN PAIN SENSITIVITY AND THRESHOLDS BETWEEN OPIOID-NAIVE AND OPIOID-DEPENDENT PATIENTS. MATERIALS AND METHODS: THREE ELECTRONIC DATABASES WERE USED TO CONDUCT THE LITERATURE SEARCH: PUBMED, EBSCO HOST, AND SCOPUS. A TOTAL OF 372 ABSTRACTS WERE REVIEWED, OF WHICH 46 STUDIES WERE DEEMED RELEVANT AND ARE INCLUDED IN THIS REVIEW. RESULTS: SPECIFIC GENE ALTERATIONS THAT WERE SHOWN TO AFFECT POSTOPERATIVE PAIN CONTROL INCLUDED SINGLE NUCLEOTIDE POLYMORPHISMS IN THE MU, KAPPA, AND DELTA OPIOID RECEPTORS, ION CHANNEL GENES, CYTOTOXIC T-CELLS, GLUTAMATE RECEPTORS AND CYTOKINE GENES, AMONG OTHERS. ALCOHOLISM, OBESITY, AND SMOKING WERE ALL LINKED WITH GENETIC POLYMORPHISMS THAT ALTERED PAIN SENSITIVITY. OPIOID ABUSE WAS FOUND TO BE ASSOCIATED WITH A POORER RESPONSE TO ANALGESICS POSTOPERATIVELY, AS WELL AS A RISK FOR PRESCRIPTION OVERDOSE. CONCLUSION: ALTHOUGH PAIN PERCEPTION HAS MULTIPLE COMPLEX INFLUENCES, THE GREATEST VARIABILITY SEEN IN RESPONSE TO OPIOIDS AMONG POSTOPERATIVE PATIENTS KNOWN TO DATE CAN BE TRACED TO GENETIC DIFFERENCES IN OPIOID METABOLISM. FURTHER STUDY IS NEEDED TO DETERMINE THE CLINICAL SIGNIFICANCE OF THESE GENETIC ASSOCIATIONS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
18   745  45 CANNABIS ALTERS EPIGENETIC INTEGRITY AND ENDOCANNABINOID SIGNALLING IN THE HUMAN FOLLICULAR NICHE. STUDY QUESTION: DO PHYTOCANNABINOIDS (PCS) AFFECT FOLLICULAR ENDOCANNABINOID SIGNALLING AND THE EPIGENOME IN THE SURROUNDING GRANULOSA CELLS (GCS)? SUMMARY ANSWER: EXPOSURE TO PCS INCREASES THE EXPRESSION OF ENDOCANNABINOID RECEPTORS AND REDUCES DNA METHYLATION ENZYME EXPRESSION AND GLOBAL DNA METHYLATION IN NAIVE GCS. WHAT IS KNOWN ALREADY: CANNABIS PLANT DERIVATIVES, KNOWN AS PCS, ARE USED FOR MEDICINAL AND RECREATIONAL PURPOSES. THE MAIN PC, TETRAHYDROCANNABINOL (THC), IS THE THIRD MOST COMMONLY USED SUBSTANCE BY WOMEN OF CHILDBEARING AGE, HENCE KNOWLEDGE OF THE EFFECT IT HAS ON REPRODUCTION IS OF UTMOST IMPORTANCE. THC EXERTS ITS EFFECTS VIA RECEPTORS OF THE ENDOCANNABINOID SYSTEM (ECS) AND CAN INTERFERE WITH FOLLICULOGENESIS, OOCYTE DEVELOPMENT AND OVULATION. ENDOCANNABINOIDS HAVE BEEN MEASURED IN FOLLICULAR FLUID (FF) OBTAINED DURING OOCYTE RETRIEVAL AND ARE IMPLICATED IN CONTROLLING FOLLICULOGENESIS. IT HAS BEEN ESTABLISHED THAT IN THE PLACENTA, PCS DISRUPT ENDOCANNABINOID HOMEOSTASIS VIA IMPAIRMENT OF THE SYNTHETIC AND DEGRADING ENZYMES, LEADING TO A NET INCREASE OF ENDOCANNABINOID LEVELS. FINALLY, PREVIOUS STUDIES HAVE SHOWN THAT THC ALTERS METHYLATION AND HISTONE MODIFICATIONS IN SPERM, BRAIN AND BLOOD CELLS. STUDY DESIGN, SIZE, DURATION: THIS STUDY INCLUDED AN IN VIVO COHORT ASSESSMENT OF CANNABIS EXPOSURE AND ITS EFFECTS ON THE FOLLICLE AND IN VITRO ASSAYS CONDUCTED TO VALIDATE THE IN VIVO FINDINGS AND TO EXPLORE POSSIBLE MECHANISMS OF ACTION. PARTICIPANTS/MATERIALS, SETTING, METHODS: A TOTAL OF 318 FF SAMPLES, FROM 261 PATIENTS UNDERGOING IVF TREATMENT AT A PRIVATE FERTILITY CLINIC WHO CONSENTED FOR BIOBANKING BIOLOGICAL WASTE MATERIAL BETWEEN JANUARY 2018 AND JULY 2019, WERE INCLUDED IN THIS STUDY. CONCENTRATIONS OF PCS AND ENDOCANNABINOIDS WERE ASSESSED IN FF BY LIQUID CHROMATOGRAPHY-MASS SPECTROMETRY (LC-MS/MS). EXPOSURE TO PCS WAS DETERMINED BASED ON THESE MEASURED LEVELS. LEVELS OF BOTH ENDOCANNABINOID RECEPTORS (CB1R, CB2R) AND THE DE NOVO DNA METHYLATING ENZYME, DNMT3B, IN GCS WERE ASSESSED BY FLOW CYTOMETRY BOTH IN VITRO AND IN VIVO AND GLOBAL DNA METHYLATION WAS ASSESSED IN VITRO BY ELISA. IN VIVO EFFECTS WERE ASSESSED BY COMPARING SAMPLES POSITIVE FOR AT LEAST ONE PC, WITH SAMPLES NEGATIVE FOR ALL MEASURED PCS. IN VITRO EFFECTS WERE DETERMINED IN NAIVE GCS, OBTAINED CONCURRENTLY WITH FF SAMPLES THAT HAD TESTED NEGATIVE FOR ALL PCS. THESE GCS WERE TREATED WITH DIFFERENT COMBINATIONS OF THE MAIN THREE PCS. MAIN RESULTS AND THE ROLE OF CHANCE: OVERALL, 17 PATIENTS (6.4%) WERE POSITIVE FOR CANNABIS CONSUMPTION. FURTHERMORE, THE PREVALENCE OF CANNABIS POSITIVITY IN THE FF INCREASED FROM 4% OF THE TESTED SAMPLES THAT WERE COLLECTED PRIOR TO NATIONAL LEGALISATION IN OCTOBER 2018 TO 12% OF THOSE COLLECTED FOLLOWING LEGALISATION. OF NOTE, 59% OF PATIENTS WHO TESTED POSITIVE FOR PCS (10 OF 17) REPORTED PREVIOUS OR ONGOING EXPOSURE TO CANNABIS UPON THEIR INITIAL INTAKE. ENDOCANNABINOID LEVELS WERE NOT AFFECTED BY THE PRESENCE OF PCS. CB2R WAS MORE PREVALENT THAN CB1R IN GCS AND ITS EXPRESSION INCREASED FOLLOWING ACUTE AND CHRONIC IN VITRO EXPOSURE TO PCS. THE EXPRESSION OF DNMT3B AND GLOBAL METHYLATION DECREASED FOLLOWING EXPOSURE, SUGGESTING THAT CANNABIS MAY AFFECT THE EPIGENOME IN THE FOLLICULAR NICHE. THE ACUTE CHANGES WERE SUSTAINED THROUGHOUT CHRONIC TREATMENT. LARGE SCALE DATA: N/A. LIMITATIONS, REASONS FOR CAUTION: OUR STUDY IS LIMITED BY LACK OF DETAILS REGARDING MODE, FREQUENCY AND TIMING OF PC CONSUMPTION. MOREOVER, WE WERE NOT ABLE TO ADEQUATELY ASSESS THE EFFECT OF PCS ON IMMEDIATE OR LONG-TERM CLINICAL OUTCOMES, DUE TO THE SMALL SAMPLE SIZE AND THE LACK OF FOLLOW UP. FUTURE, LARGE-SCALE STUDIES SHOULD FOCUS ON ASSESS THE CLINICAL IMPLICATIONS OF CANNABIS EXPOSURE, VALIDATE OUR FINDINGS, AND DETERMINE TO WHAT EXTENT CANNABIS AFFECTS THE EPIGENOME OVARIAN FOLLICLE AND THE DEVELOPING OOCYTE. WIDER IMPLICATIONS OF THE FINDINGS: TO OUR KNOWLEDGE, THIS IS THE FIRST STUDY MEASURING PCS IN FF BY LC-MS/MS. WE SHOW THAT CONSUMING CANNABIS ALTERS THE ECS IN THE DEVELOPING FOLLICLE, AND DIRECTLY AFFECTS DNMT EXPRESSION AND GLOBAL DNA METHYLATION LEVELS. CANNABIS LEGALISATION AND USE IS INCREASING WORLDWIDE, THEREFORE FURTHER UNDERSTANDING ITS ROLE IN FEMALE FERTILITY AND FOLLICULOGENESIS IS CRITICAL. STUDY FUNDING/COMPETING INTEREST(S): ALL FUNDING WAS PROVIDED BY CREATE FERTILITY CENTRE THROUGH THE REINVESTMENT OF CLINICAL EARNINGS. THE AUTHORS DECLARE NO COMPETING INTERESTS.	2021	

19   108  27 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
20  3304  31 HIGH-GLUCOSE CONCENTRATIONS CHANGE DNA METHYLATION LEVELS IN HUMAN IVM OOCYTES. STUDY QUESTION: WHAT ARE THE EFFECTS OF HIGH-GLUCOSE CONCENTRATIONS ON DNA METHYLATION OF HUMAN OOCYTES? SUMMARY ANSWER: HIGH-GLUCOSE CONCENTRATIONS ALTERED DNA METHYLATION LEVELS OF PEG3 AND ADIPONECTIN IN HUMAN IN VITRO MATURATION OOCYTES. WHAT IS KNOWN ALREADY: MATERNAL DIABETES HAS A DETRIMENTAL INFLUENCE ON OOCYTE QUALITY INCLUDING EPIGENETIC MODIFICATIONS, AS SHOWN IN NON-HUMAN MAMMALIAN SPECIES. STUDY DESIGN, SIZE, DURATION: IMMATURE METAPHASE I (MI) STAGE OOCYTES OF GOOD QUALITY WERE RETRIEVED FROM PATIENTS WHO HAD NORMAL OVARIAN POTENTIAL AND WHO UNDERWENT ICSI IN THE REPRODUCTIVE MEDICINE CENTER OF PEOPLE'S HOSPITAL OF ZHENGZHOU UNIVERSITY. MI OOCYTES WERE CULTURED IN MEDIUM WITH DIFFERENT GLUCOSE CONCENTRATIONS (CONTROL, 10 MM AND 15 MM) IN VITRO AND 48 H LATER, OOCYTES WITH FIRST POLAR BODY EXTRUSION WERE COLLECTED TO CHECK THE DNA METHYLATION LEVELS. PARTICIPANTS/MATERIALS, SETTING, METHODS: MI OOCYTES UNDERWENT IN VITRO MATURATION (IVM) AT 37 DEGREES C WITH 5% MIXED GAS FOR 48 H. THEN THE MATURE OOCYTES WERE TREATED WITH BISULFITE BUFFER. TARGET SEQUENCES WERE AMPLIFIED USING NESTED OR HALF-NESTED PCR AND THE DNA METHYLATION STATUS WAS TESTED USING COMBINED BISULFITE RESTRICTION ANALYSIS (COBRA) AND BISULFITE SEQUENCING (BS). MAIN RESULTS AND THE ROLE OF CHANCE: HIGH-GLUCOSE CONCENTRATIONS SIGNIFICANTLY DECREASED THE FIRST POLAR BODY EXTRUSION RATE. COMPARED TO CONTROLS, THE DNA METHYLATION LEVELS OF PEG3 IN HUMAN IVM OOCYTES WERE SIGNIFICANTLY HIGHER IN 10 MM (P < 0.001) AND 15 MM (P < 0.001) CONCENTRATIONS OF GLUCOSE. BUT THE DNA METHYLATION LEVEL OF H19 WAS NOT AFFECTED BY HIGH-GLUCOSE CONCENTRATIONS IN HUMAN IVM OOCYTES. WE ALSO FOUND THAT THERE WAS A DECREASE IN DNA METHYLATION LEVELS IN THE PROMOTER OF ADIPONECTIN IN HUMAN IVM OOCYTES BETWEEN CONTROLS AND OOCYTES EXPOSED TO 10 MM GLUCOSE (P = 0.028). LARGE SCALE DATA: N/A. LIMITATIONS REASONS FOR CAUTION: IT IS NOT CLEAR WHETHER THE ALTERATIONS ARE BENEFICIAL OR NOT FOR THE EMBRYO DEVELOPMENT AND OFFSPRING HEALTH. THE EFFECTS OF HIGH-GLUCOSE CONCENTRATIONS ON THE WHOLE PROCESS OF OOCYTE MATURATION ARE STILL NOT ELUCIDATED. ANOTHER ISSUE IS THAT THE NUMBER OF OOCYTES USED IN THIS STUDY WAS LIMITED. WIDER IMPLICATIONS OF THE FINDINGS: THIS IS THE FIRST TIME THAT THE EFFECTS OF HIGH-GLUCOSE CONCENTRATION ON DNA METHYLATION OF HUMAN OOCYTES HAVE BEEN ELUCIDATED. OUR RESULT INDICATES THAT IN HUMANS, THE HIGH RISK OF CHRONIC DISEASES IN OFFSPRING FROM DIABETIC MOTHERS MAY ORIGINATE FROM ABNORMAL DNA MODIFICATIONS IN OOCYTES.
