1   983 135 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

2  1854  49 ELEVATED SEMINAL PLASMA ESTRADIOL AND EPIGENETIC INACTIVATION OF ESR1 AND ESR2 IS ASSOCIATED WITH CP/CPPS. CHRONIC PROSTATITIS/CHRONIC PELVIC PAIN SYNDROME (CP/CPPS) IS ASSOCIATED WITH URINARY TRACT SYMPTOMS AND HORMONAL IMBALANCES AMONGST OTHERS. THE HETEROGENEOUS CLINICAL PRESENTATION, UNEXPLORED MOLECULAR BACKGROUND AND LACK OF PROSTATE BIOPSIES COMPLICATE THERAPY. HERE, USING LIQUID BIOPSIES, WE PERFORMED A COMPREHENSIVE TRANSLATIONAL STUDY ON MEN DIAGNOSED WITH CP/CPPS TYPE III (N= 50; MEDIAN AGE 39.8, RANGE 23-65) AND AGE-MATCHED CONTROLS (N= 61; MEDIAN AGE 36.8, RANGE 20-69), CONSIDERING BIOCHEMICAL PARAMETERS OF BLOOD AND EJACULATES, AND EPIGENETIC REGULATION OF THE ESTROGEN RECEPTOR GENES (ESR1 AND ESR2) IN LEUKOCYTES ISOLATED FROM BLOOD (SYSTEMIC REGULATION) AND IN SOMATIC CELLS ISOLATED FROM EJACULATES (LOCAL REGULATION). WE FOUND ELEVATED 17BETA-ESTRADIOL (E(2)) LEVELS IN SEMINAL PLASMA, BUT NOT IN BLOOD PLASMA, THAT WAS SIGNIFICANTLY ASSOCIATED WITH CP/CPPS AND IMPAIRED URINARY TRACT SYMPTOMS. IN EJACULATED SOMATIC CELLS OF CP/CPPS PATIENTS WE FOUND THAT ESR1 AND ESR2 WERE BOTH SIGNIFICANTLY HIGHER METHYLATED IN CPG-PROMOTERS AND EXPRESSIONALLY DOWN-REGULATED IN COMPARISON TO CONTROLS. MAST CELLS ARE REPORTED TO CONTRIBUTE TO CP/CPPS AND ARE ESTROGEN RESPONSIVE. CONSISTENT WITH THIS, WE FOUND THAT E(2) -TREATMENT OF HUMAN MAST CELL LINES (HMC-1 AND LAD2) RESULTED IN ALTERED CYTOKINE AND CHEMOKINE EXPRESSION. INTERESTINGLY, IN HMC-1 CELLS, POSSESSING EPIGENETICALLY INACTIVATED ESR1 AND ESR2, E(2) -TREATMENT LED TO A REDUCED TRANSCRIPTION OF A NUMBER OF INFLAMMATORY GENES. OVERALL, THESE DATA SUGGEST THAT ELEVATED LOCAL E(2) LEVELS ASSOCIATE WITH AN EPIGENETIC DOWN-REGULATION OF THE ESTROGEN RECEPTORS AND HAVE A PROMINENT ROLE IN CP/CPPS. INVESTIGATING E(2) LEVELS IN SEMEN COULD THEREFORE SERVE AS A PROMISING BIOMARKER TO SELECT PATIENTS FOR ESTROGEN TARGETED THERAPY.	2018

3  4806  31 OBESITY AND METABOLIC SYNDROME ASSOCIATED WITH SYSTEMIC INFLAMMATION AND THE IMPACT ON THE MALE REPRODUCTIVE SYSTEM. OBESITY AND METABOLIC SYNDROME (METS) ARE GLOBAL EPIDEMICS, DRIVEN BY AN OBESOGENIC ENVIRONMENT. THIS IS MEDIATED BY COMPLEX UNDERLYING PATHOPHYSIOLOGY, IN WHICH CHRONIC INFLAMMATION IS AN IMPORTANT AETIOLOGICAL AND MECHANISTIC PHENOMENON. A SHIFT TOWARDS A SUBCLINICAL T(H) 1-LYMPHOCYTE MEDIATED INNATE AND CHRONIC INFLAMMATORY RESPONSE IS WELL DEFINED IN OBESITY AND METS, DEMONSTRATED IN MULTIPLE SYSTEMS INCLUDING VISCERAL ADIPOSITY, BRAIN (HYPOTHALAMUS), MUSCLES, VASCULATURE, LIVER, PANCREAS, TESTES, EPIDIDYMIS, PROSTATE AND SEMINAL FLUID. INFLAMMATORY CYTOKINES DISRUPT THE HYPOTHALAMIC-PITUITARY-TESTES AXIS AND STEROIDOGENESIS CASCADES (HYPOGONADOTROPIC HYPOGONADISM), SPERMATOGENESIS (POOR SEMEN PARAMETERS, INCLUDING DNA FRAGMENTATION AND DETRIMENTAL EPIGENETIC MODIFICATION) AND RESULTS IN SUBCLINICAL PROSTATITIS AND PROSTATE HYPERPLASIA. THIS REVIEW AIMS TO HIGHLIGHT THE ROLE OF CHRONIC INFLAMMATION IN OBESITY AND METS, CYTOKINES IN MALE REPRODUCTIVE PHYSIOLOGY AND PATHOPHYSIOLOGY, THE IMPACT ON STEROIDOGENESIS AND SPERMATOGENESIS, PROSTATE PATHOLOGY AND ERECTILE DYSFUNCTION. CURRENTLY, IT IS RECOMMENDED THAT CLINICAL ASSESSMENT OF MALE INFERTILITY AND REPRODUCTIVE DYSFUNCTION IN OBESE AND METS PATIENTS INCLUDES INFLAMMATION ASSESSMENT (HIGHLY SENSITIVE C-REACTIVE PROTEIN), AND APPROPRIATE ADVICE AND THERAPEUTIC OPTIONS ARE INCORPORATED IN THE MANAGEMENT OPTIONS. HOWEVER, THE MECHANISMS AND THERAPEUTIC OPTIONS REMAIN POORLY UNDERSTOOD AND REQUIRE SIGNIFICANT INTERDISCIPLINARY RESEARCH TO IDENTIFY POTENTIAL NOVEL THERAPEUTIC STRATEGIES.	2019





4  4523  59 MULTIDISCIPLINARY APPROACH TO PROSTATITIS. THE MODERN CLINICAL RESEARCH ON PROSTATITIS STARTED WITH THE WORK OF STAMEY AND COWORKERS WHO DEVELOPED THE BASIC PRINCIPLES WE ARE STILL USING. THEY ESTABLISHED THE SEGMENTED CULTURE TECHNIQUE FOR LOCALIZING THE INFECTIONS IN THE MALES TO THE URETHRA, THE BLADDER, OR THE PROSTATE AND TO DIFFERENTIATE THE MAIN CATEGORIES OF PROSTATITIS. SUCH CATEGORIES WITH SLIGHT MODIFICATIONS ARE STILL USED ACCORDING TO THE NIH CLASSIFICATION: ACUTE BACTERIAL PROSTATITIS, CHRONIC BACTERIAL PROSTATITIS, CHRONIC PELVIC PAIN SYNDROME (CPPS) AND ASYMPTOMATIC PROSTATITIS. PROSTATIC INFLAMMATION IS CONSIDERED AN IMPORTANT FACTOR IN INFLUENCING BOTH PROSTATIC GROWTH AND PROGRESSION OF SYMPTOMS OF BENIGN PROSTATIC HYPERPLASIA AND PROSTATITIS. CHRONIC INFLAMMATION/NEUROINFLAMMATION IS A RESULT OF A DEREGULATED ACUTE PHASE RESPONSE OF THE INNATE IMMUNE SYSTEM AFFECTING SURROUNDING NEURAL TISSUE AT MOLECULAR, STRUCTURAL AND FUNCTIONAL LEVELS. CLINICAL OBSERVATIONS SUGGEST THAT CHRONIC INFLAMMATION CORRELATES WITH CHRONIC PROSTATITIS/CHRONIC PELVIC PAIN SYNDROME (CP/CPPS) AND BENIGN PROSTATIC HYPERPLASIA (BPH) AND AN HISTORY OF CLINICAL CHRONIC PROSTATITIS SIGNIFICANTLY INCREASES THE ODDS FOR PROSTATE CANCER. THE NIHNIDDK CLASSIFICATION BASED ON THE USE OF THE MICROBIOLOGICAL 4- GLASSES LOCALIZATION TEST OR SIMPLIFIED 2-GLASSES TEST, IS CURRENTLY ACCEPTED WORLDWIDE. THE UPOINT SYSTEM IDENTIFIES GROUPS OF CLINICIANS WITH HOMOGENEOUS CLINICAL PRESENTATION AND IS USED TO RECOGNIZE PHENOTYPES TO BE SUBMITTED TO SPECIFIC TREATMENTS. THE UPOINTS ALGORITHM IMPLEMENTED THE ORIGINAL UPOINT ADDING TO THE URINARY DOMAINS (U), PSYCHO-SOCIAL (P), ORGANSPECIFIC (O), INFECTION (I), NEUROLOGICAL (N), MUSCLE TENSION AND TENDERNESS (T) A FURTHER DOMAIN RELATED TO SEXUALITY (S). IN FACT SEXUAL DYSFUNCTION (ERECTILE, EJACULATORY, LIBIDO LOSS) HAS BEEN DESCRIBED IN 46-92% OF CASES WITH A HIGH IMPACT ON THE QUALITY OF LIFE OF PATIENTS WITH CP/CPPS. PROSTATIC ULTRASOUND REPRESENTS THE MOST POPULAR IMAGING TEST IN THE WORK-UP OF EITHER ACUTE AND CHRONIC PROSTATITIS ALTHOUGH NO SPECIFIC HYPO-HYPERECHOIC PATTERN HAS BEEN CLEARLY ASSOCIATED WITH CHRONIC BACTERIAL PROSTATITIS AND CPPS. USE OF A DIGITAL-PROCESSING SOFTWARE TO CALCULATE THE EXTENSION OF PROSTATIC CALCIFICATION AREA AT ULTRASOUND DEMONSTRATED A HIGHER PERCENTAGE OF PROSTATIC CALCIFICATION IN PATIENTS WITH CHRONIC BACTERIAL PROSTATITIS. MULTIPARAMETRIC MAGNETIC RESONANCE IMAGING (MPMRI) IS THE CURRENT STATE-OF-THE ART IMAGING MODALITY IN THE ASSESSMENT OF PATIENTS WITH PROSTATE CANCER ALTHOUGH A VARIETY OF BENIGN CONDITIONS, INCLUDING INFLAMMATION, MAY MIMIC PROSTATE CANCER AND ACT AS CONFOUNDING FACTORS IN THE DISCRIMINATION BETWEEN NEOPLASTIC AND NON-NEOPLASTIC LESIONS. BACTERIA CAN INFECT PROSTATE GLAND BY: ASCENDING THE URETHRA, REFLUX OF URINE INTO THE PROSTATIC DUCTS, DIRECT INOCULATION OF BACTERIA THROUGH INSERTED BIOPSY NEEDLES OR HEMATOGENOUS SEEDING. ENTEROBACTERIACEAE ARE THE PREDOMINANT PATHOGENS IN ACUTE AND CHRONIC BACTERIAL PROSTATITIS, BUT AN INCREASING ROLE OF ENTEROCOCCI HAS BEEN REPORTED. MANY STRAINS OF THESE UROPATHOGENS EXHIBIT THE ABILITY TO FORM BIOFILM AND MULTIDRUG- RESISTANCE. SEXUALLY TRANSMITTED INFECTIONS (STI) AGENTS, IN PARTICULAR CHLAMYDIA TRACHOMATIS AND MYCOPLASMA GENITALIUM, HAVE BEEN ALSO CONSIDERED AS CAUSATIVE PATHOGENS OF CHRONIC BACTERIAL PROSTATITIS. ON THE CONTRARY THE EFFECTIVE ROLE IN GENITAL DISEASES OF OTHER "GENITAL MYCOPLASMAS" IS STILL A MUCH DEBATED ISSUE. SEXUALLY TRANSMITTED INFECTIONS AGENTS SHOULD BE INVESTIGATED BY MOLECULAR METHODS IN BOTH PATIENT AND SEXUAL PARTNER. "NEXT GENERATION" INVESTIGATIONS, SUCH AS CYTOKINE ANALYSIS, CYTOLOGICAL TYPING OF IMMUNE CELLS COULD HELP STRATIFYING THE IMMUNE RESPONSE. EPIGENETIC DYSREGULATION OF INFLAMMATORY FACTORS SHOULD BE INVESTIGATED ACCORDING TO SYSTEMIC AND COMPARTMENT-SPECIFIC SIGNALS. THE SEARCH FOR BIOMARKERS SHOULD ALSO INCLUDE EVALUATION OF HORMONAL PATHWAYS, AS MEASUREMENT OF ESTROGEN LEVELS IN SEMEN. ANTIMICROBIALS ARE THE FIRST LINE AGENTS FOR THE TREATMENT OF BACTERIAL PROSTATITIS. THE SUCCESS OF ANTIMICROBIAL TREATMENT DEPENDS ON THE ANTIBACTERIAL ACTIVITY AND THE PHARMACOKINETIC CHARACTERISTICS OF THE DRUG WHICH MUST REACH HIGH CONCENTRATIONS IN PROSTATE SECRETION AND PROSTATE TISSUE. ACUTE BACTERIAL PROSTATITIS CAN BE A SERIOUS INFECTION WITH A POTENTIAL RISK FOR UROSEPSIS FOR IINITIAL TREATMENT OF SEVERELY ILL PATIENTS, INTRAVENOUS ADMINISTRATION OF HIGH DOSES OF BACTERICIDAL ANTIMICROBIALS, SUCH AS BROAD-SPECTRUM PENICILLINS, THIRD-GENERATION CEPHALOSPORINS OR FLUOROQUINOLONES, IS RECOMMENDED IN COMBINATION WITH AN AMINOGLYCOSIDE. USE OF PIPERACILLIN-TAZOBACTAM AND MEROPENEM IS JUSTIFIED IN PRESENCE OF MULTIRESISTANT GRAMNEGATIVE PATHOGENS. THE ANTIBIOTIC TREATMENT OF CHRONIC PROSTATITIS IS CURRENTLY BASED ON THE USE OF FLUOROQUINOLONES THAT, GIVEN FOR 2 TO 4 WEEKS, CURED ABOUT 70% OF MEN WITH CHRONIC BACTERIAL PROSTATITIS. FOR THE TREATMENT OF CHLAMYDIAL PROSTATITIS MACROLIDES WERE SHOWN TO BE MORE EFFECTIVE THAN FLUOROQUINOLONES, WHEREAS NO DIFFERENCES WERE OBSERVED IN MICROBIOLOGICAL AND CLINICAL EFFICACY BETWEEN MACROLIDES AND TETRACYCLINES FOR THE TREATMENT OF INFECTIONS CAUSED BY INTRACELLULAR PATHOGENS. AMINOGLYCOSIDES AND FOSFOMYCIN COULD BE CONSIDERED AS A THERAPEUTIC ALTERNATIVE FOR THE TREATMENT OF QUINOLONE RESISTANT PROSTATITIS. USE OF ALPHA-BLOCKERS IN CP/CPPS PATIENTS WITH URINARY SYMPTOMS AND ANALGESICS +/- NON STEROIDAL ANTI-INFLAMMATORY DRUGS (NSAID), IN PRESENCE OF PAIN DEMONSTRATED A REDUCTION OF SYMPTOMS REDUCTION AND AN IMPROVEMENT OF QUALITY OF LIFE, ALTHOUGH LONG TERM USE OF NSAID IS LIMITED BY SIDE EFFECT PROFILE. HOWEVER, THE MULTIMODAL THERAPEUTIC REGIMEN BY CONTEMPORARY USE OF ALPHABLOCKERS, ANTIBIOTICS AND ANTI-INFLAMMATORY SHOWED A BETTER CONTROL OF PROSTATITIS SYMPTOMS THAN SINGLE DRUG TREATMENT. NOVEL THERAPEUTIC SUBSTANCES FOR THE TREATMENT OF PAIN, SUCH AS THE CANNABINOID ANANDAMIDE WOULD BE HIGHLY INTERESTING TO TEST. AN ALTERNATIVE FOR THE TREATMENT OF CHRONIC PROSTATITIS/CHRONIC PELVIC PAIN SYNDROME IS PHYTOTHERAPY, AS PRIMARY THERAPY OR IN ASSOCIATION WITH OTHER DRUGS. QUERCETIN, POLLEN EXTRACT, EXTRACT OF SERENOA REPENS AND OTHER MIXTURES OF HERBAL EXTRACTS SHOWED A POSITIVE EFFECT ON SYMPTOMS AND QUALITY OF LIFE WITHOUT SIDE EFFECTS. THE ASSOCIATION OF CP/CPPS WITH ALTERATIONS OF INTESTINAL FUNCTION HAS BEEN DESCRIBED. DIET HAS ITS EFFECTS ON INFLAMMATION BY REGULATION OF THE COMPOSITION OF INTESTINAL FLORA AND DIRECT ACTION ON THE INTESTINAL CELLS (STERILE INFLAMMATION). INTESTINAL BACTERIA (MICROBIOTA) INTERACTS WITH FOOD INFLUENCING THE METABOLIC, IMMUNE AND INFLAMMATORY RESPONSE OF THE ORGANISM. THE INTESTINAL MICROBIOTA HAS PROTECTIVE FUNCTION AGAINST PATHOGENIC BACTERIA, METABOLIC FUNCTION BY SYNTHESIS OF VITAMINS, DECOMPOSITION OF BILE ACIDS AND PRODUCTION OF TROPHIC FACTORS (BUTYRATE), AND MODULATION OF THE INTESTINAL IMMUNE SYSTEM. THE ALTERATION OF THE MICROBIOTA IS CALLED "DYSBIOSIS" CAUSING INVASIVE INTESTINAL DISEASES PATHOLOGIES (LEAKY GUT SYNDROME AND FOOD INTOLERANCES, IRRITABLE BOWEL SYNDROME OR CHRONIC INFLAMMATORY BOWEL DISEASES) AND CORRELATING WITH NUMEROUS SYSTEMIC DISEASES INCLUDING ACUTE AND CHRONIC PROSTATITIS. ADMINISTRATION OF LIVE PROBIOTICS BACTERIA CAN BE USED TO REGULATE THE BALANCE IF INTESTINAL FLORA. SESSIONS OF HYDROCOLONTHERAPY CAN REPRESENT AN INTEGRATION TO THIS THERAPEUTIC APPROACH. FINALLY, MICROBIOLOGICAL EXAMINATION OF SEXUAL PARTNERS CAN OFFER SUPPLEMENTARY INFORMATION FOR TREATMENT.	2019	

5  4853  44 OPPOSING EPIGENETIC SIGNATURES IN HUMAN SPERM BY INTAKE OF FAST FOOD VERSUS HEALTHY FOOD. ANIMAL EXPERIMENTS HAVE DEMONSTRATED THAT DIETS HIGH IN FATS CREATE A HARMFUL ENVIRONMENT FOR DEVELOPING SPERM CELLS, CONTRIBUTING TO IMPAIRED REPRODUCTIVE HEALTH AND INDUCED RISK FOR CHRONIC DISEASES IN THE NEXT GENERATION. CHANGES AT THE LEVEL OF THE EPIGENOME HAVE BEEN SUGGESTED TO UNDERLIE THESE OBSERVATIONS. HUMAN DATA ARE LIMITED TO VERIFY THIS HYPOTHESIS. WHILE WE EARLIER DEMONSTRATED A LINK BETWEEN MALE OBESITY AND DNA METHYLATION CHANGES AT IMPRINTED GENES IN MATURE SPERM CELLS AND NEWBORNS, IT IS CURRENTLY UNKNOWN IF -OR HOW- A PATERNAL EATING PATTERN (RELATED TO OBESITY) IS RELATED TO INDICES FOR EPIGENETIC INHERITANCE. WE HERE AIM TO EXAMINE A YET UNEXPLORED LINK BETWEEN CONSUMPTION OF HEALTHY (RICH IN VITAMINS AND FIBERS) OR UNHEALTHY ("FAST") FOODS AND METHYLATION AT IMPRINT REGULATORY REGIONS IN DNA OF SPERM. WE OBTAINED SEMEN AND DATA FROM 67 MEN, AS PART OF A NORTH CAROLINA-BASED STUDY: THE INFLUENCE OF THE ENVIRONMENT ON GAMETIC EPIGENETIC REPROGRAMMING (TIEGER) STUDY. DIETARY DATA INCLUDED INTAKE OF FRUITS/NUTS, VEGETABLES/SOUPS, WHOLE GRAIN BREAD, MEAT, SEAFOOD/FISH, AND FATTY OR PROCESSED FOOD ITEMS. MULTIPLE REGRESSION MODELS WERE USED TO EXPLORE THE ASSOCIATION BETWEEN DIETARY HABITS AND CLINICAL SPERM PARAMETERS AS WELL AS DNA METHYLATION LEVELS, QUANTIFIED USING BISULFITE PYROSEQUENCING AT 12 DIFFERENTIALLY METHYLATED REGIONS (DMRS) OF THE FOLLOWING IMPRINTED GENES: GRB10, IGF2, H19, MEG3, NDN, NNAT, PEG1/MEST, PEG3, PLAGL1, SNRPN, AND SGCE/PEG10. AFTER ADJUSTING FOR AGE, OBESITY STATUS AND RECRUITMENT METHOD, WE FOUND THAT TOTAL MOTILE COUNT (TMC) WAS SIGNIFICANTLY HIGHER IF MEN CONSUMED FRUITS/NUTS (BETA=+6.9, SE=1.9, P=0.0005) AND VEGETABLES (BETA=+5.4, SE=1.9, P=0.006), WHEREAS CONSUMPTION OF FRIES WAS ASSOCIATED WITH LOWER TMC (BETA=-20.2, SE=8.7, P=0.024). SEMEN VOLUME WAS ALSO HIGHER IF VEGETABLES OR FRUITS/NUTS WERE FREQUENTLY CONSUMED (BETA=+0.06, SE=0.03, P=0.03). SIMILARLY, OUR SPERM EPIGENETIC ANALYSES SHOWED OPPOSING ASSOCIATIONS FOR HEALTHY VERSUS FAST FOOD ITEMS. FREQUENT CONSUMPTION OF FRIES WAS RELATED TO A HIGHER CHANCE OF SPERM BEING METHYLATED AT THE MEG3-IG CPG4 SITE (OR=1.073, 95%CI: 1.035-1.112), AND HIGH CONSUMPTION OF VEGETABLES WAS ASSOCIATED WITH A LOWER RISK OF DNA METHYLATION AT THE NNAT CPG3 SITE (OR=0.941, 95%CI: 0.914-0.968). THESE RESULTS REMAINED SIGNIFICANT AFTER ADJUSTING FOR MULTIPLE TESTING. WE CONCLUDE THAT DIETARY HABITS ARE LINKED TO SPERM EPIGENETIC OUTCOMES. IF CARRIED INTO THE NEXT GENERATION PATERNAL UNHEALTHY DIETARY PATTERNS MAY RESULT IN ADVERSE METABOLIC CONDITIONS AND INCREASED RISK FOR CHRONIC DISEASES IN OFFSPRING.	2021

6  5628  37 SEMEN ABNORMALITIES, SPERM DNA DAMAGE AND GLOBAL HYPERMETHYLATION IN HEALTH WORKERS OCCUPATIONALLY EXPOSED TO IONIZING RADIATION. BACKGROUND: CYTOGENETIC STUDIES HAVE DEMONSTRATED THAT LOW LEVELS OF CHRONIC RADIATION EXPOSURE CAN POTENTIALLY INCREASE THE FREQUENCY OF CHROMOSOMAL ABERRATIONS AND ANEUPLOIDY IN SOMATIC CELLS. EPIDEMIOLOGICAL STUDIES HAVE SHOWN THAT HEALTH WORKERS OCCUPATIONALLY EXPOSED TO IONIZING RADIATION BEAR AN INCREASED RISK OF HEMATOLOGICAL MALIGNANCIES. OBJECTIVES: TO FIND THE INFLUENCE OF OCCUPATIONAL RADIATION EXPOSURE ON SEMEN CHARACTERISTICS, INCLUDING GENETIC AND EPIGENETIC INTEGRITY OF SPERMATOZOA IN A CHRONICALLY EXPOSED POPULATION. METHODS: THIS CROSS SECTIONAL STUDY INCLUDED 134 MALE VOLUNTEERS OF WHICH 83 WERE OCCUPATIONALLY EXPOSED TO IONIZING RADIATION AND 51 WERE NON-EXPOSED CONTROL SUBJECTS. SEMEN CHARACTERISTICS, SPERM DNA FRAGMENTATION, ANEUPLOIDY AND INCIDENCE OF GLOBAL HYPERMETHYLATION IN THE SPERMATOZOA WERE DETERMINED AND COMPARED BETWEEN THE NON-EXPOSED AND THE EXPOSED GROUP. RESULTS: DIRECT COMPARISON OF THE SEMEN CHARACTERISTICS BETWEEN THE NON-EXPOSED AND THE EXPOSED POPULATION REVEALED SIGNIFICANT DIFFERENCES IN MOTILITY CHARACTERISTICS, VIABILITY, AND MORPHOLOGICAL ABNORMALITIES (P<0.05-0.0001). ALTHOUGH, THE LEVEL OF SPERM DNA FRAGMENTATION WAS SIGNIFICANTLY HIGHER IN THE EXPOSED GROUP AS COMPARED TO THE NON-EXPOSED GROUP (P<0.05-0.0001), THE INCIDENCE OF SPERM ANEUPLOIDY WAS NOT STATISTICALLY DIFFERENT BETWEEN THE TWO GROUPS. HOWEVER, A SIGNIFICANT NUMBER OF HYPERMETHYLATED SPERMATOZOA WERE OBSERVED IN THE EXPOSED GROUP IN COMPARISON TO NON-EXPOSED GROUP (P<0.05). CONCLUSIONS: WE PROVIDE THE FIRST EVIDENCE ON THE DETRIMENTAL EFFECTS OF OCCUPATIONAL RADIATION EXPOSURE ON FUNCTIONAL, GENETIC AND EPIGENETIC INTEGRITY OF SPERM IN HEALTH WORKERS. HOWEVER, FURTHER STUDIES ARE REQUIRED TO CONFIRM THE POTENTIAL DETRIMENTAL EFFECTS OF IONIZING RADIATION IN THESE SUBJECTS.	2013

7  4804  32 OBESITY AND MALE INFERTILITY: MECHANISMS AND MANAGEMENT. OBESITY IS CONSIDERED A GLOBAL HEALTH PROBLEM AFFECTING MORE THAN A THIRD OF THE POPULATION. COMPLICATIONS OF OBESITY INCLUDE CARDIOVASCULAR DISEASES, TYPE 2 DIABETES MELLITUS, MALIGNANCY (INCLUDING PROSTATIC CANCER), NEURODEGENERATION AND ACCELERATED AGEING. IN MALES, THESE FURTHER INCLUDE ERECTILE DYSFUNCTION, POOR SEMEN QUALITY AND SUBCLINICAL PROSTATITIS. ALTHOUGH POORLY UNDERSTOOD, IMPORTANT MEDIATORS OF OBESITY THAT MAY INFLUENCE THE MALE REPRODUCTIVE SYSTEM INCLUDE HYPERINSULINEMIA, HYPERLEPTINEMIA, CHRONIC INFLAMMATION AND OXIDATIVE STRESS. OBESITY IS KNOWN TO DISRUPT MALE FERTILITY AND THE REPRODUCTION POTENTIAL, PARTICULARLY THROUGH ALTERATION IN THE HYPOTHALAMIC-PITUITARY-GONADAL AXIS, DISRUPTION OF TESTICULAR STEROIDOGENESIS AND METABOLIC DYSREGULATION, INCLUDING INSULIN, CYTOKINES AND ADIPOKINES. IMPORTANTLY, OBESITY AND ITS UNDERLYING MEDIATORS RESULT IN A NEGATIVE IMPACT ON SEMEN PARAMETERS, INCLUDING SPERM CONCENTRATION, MOTILITY, VIABILITY AND NORMAL MORPHOLOGY. MOREOVER, OBESITY INHIBITS CHROMATIN CONDENSATION, DNA FRAGMENTATION, INCREASES APOPTOSIS AND EPIGENETIC CHANGES THAT CAN BE TRANSFERRED TO THE OFFSPRING. THIS REVIEW DISCUSSES THE IMPACT OF OBESITY ON THE MALE REPRODUCTIVE SYSTEM AND FERTILITY, INCLUDING ASSOCIATED MECHANISMS. FURTHERMORE, WEIGHT MANAGEMENT STRATEGIES, LIFESTYLE CHANGES, PRESCRIPTION MEDICATION, AND COMPLEMENTARY AND ALTERNATIVE MEDICINE IN THE MANAGEMENT OF OBESITY-INDUCED SUBFERTILITY IS DISCUSSED.	2021

8  3556  31 IMPACT OF ALCOHOL CONSUMPTION ON MALE FERTILITY POTENTIAL: A NARRATIVE REVIEW. ALCOHOL ABUSE DISORDER IS A SERIOUS CONDITION, IMPLICATING MORE THAN 15 MILLION PEOPLE AGED 12 YEARS AND OLDER IN 2019 IN THE UNITED STATES. ETHANOL (OR ETHYL ALCOHOL) IS MAINLY OXIDIZED IN THE LIVER, RESULTING IN THE SYNTHESIS OF ACETALDEHYDE AND ACETATE, WHICH ARE TOXIC AND CARCINOGENIC METABOLITES, AS WELL AS IN THE GENERATION OF A REDUCTIVE CELLULAR ENVIRONMENT. MOREOVER, ETHANOL CAN INTERACT WITH LIPIDS, GENERATING FATTY ACID ETHYL ESTERS AND PHOSPHATIDYLETHANOL, WHICH INTERFERE WITH PHYSIOLOGICAL CELLULAR PATHWAYS. THIS NARRATIVE REVIEW SUMMARIZES THE IMPACT OF EXCESSIVE ALCOHOL CONSUMPTION ON MALE FERTILITY BY DESCRIBING ITS METABOLISM AND HOW ETHANOL CONSUMPTION MAY INDUCE CELLULAR DAMAGE. FURTHERMORE, THE IMPACT OF ALCOHOL CONSUMPTION ON HORMONAL REGULATION, SEMEN QUALITY, AND GENETIC AND EPIGENETIC REGULATIONS IS DISCUSSED BASED ON EVIDENCE FROM ANIMAL AND HUMAN STUDIES, FOCUSING ON THE CONSEQUENCES ON THE OFFSPRING. FINALLY, THE LIMITATIONS OF THE CURRENT EVIDENCE ARE DISCUSSED. OUR REVIEW HIGHLIGHTS THE ASSOCIATION BETWEEN CHRONIC ALCOHOL CONSUMPTION AND POOR SEMEN QUALITY, MAINLY DUE TO THE DEVELOPMENT OF OXIDATIVE STRESS, AS WELL AS ITS GENOTOXIC IMPACT ON HORMONAL REGULATION AND DNA INTEGRITY, AFFECTING THE OFFSPRING'S HEALTH. NEW LANDSCAPES OF INVESTIGATION ARE PROPOSED FOR THE IDENTIFICATION OF MOLECULAR MARKERS FOR ALCOHOL-ASSOCIATED INFERTILITY, WITH A FOCUS ON ADVANCED OMICS-BASED APPROACHES APPLIED TO THE ANALYSIS OF SEMEN SAMPLES.	2021

9  6840  26 [MALE INFERTILITY AND UROLOGIC CANCERS: ADVANCES IN STUDIES]. MALE INFERTILITY IS ONE OF THE MOST COMMON DISEASES IN ANDROLOGY. STUDIES SHOW THAT MALE INFERTILITY IS SIGNIFICANTLY CORRELATED WITH THE INCIDENCE AND MORTALITY OF TUMORS, ESPECIALLY MALIGNANT TUMORS IN THE GENITOURINARY SYSTEM, SUCH AS TESTIS CANCER AND PROSTATE CANCER. THE RELATIONSHIP OF MALE INFERTILITY WITH GENITOURINARY SYSTEM TUMORS INVOLVES VARIOUS ASPECTS, MAINLY INCLUDING CHANGES IN CHROMOSOME MUTATIONS, EPIGENETIC MARKS, HORMONAL IMBALANCE, AND CONGENITAL DEFORMITY. BESIDES, SOME CHRONIC DISEASES ARE SHOWN TO BE SIGNIFICANTLY ASSOCIATED WITH MALE INFERTILITY, AND SEMEN QUALITY OR FERTILITY STATUS MAY BE BIOMARKERS OF THE OVERALL HEALTH OF MALES. IN-DEPTH STUDIES OF THE CORRELATION BETWEEN MALE INFERTILITY AND THESE FACTORS ARE VERY IMPORTANT FOR AN INSIGHT INTO THE PATHOGENESIS AND PREVENTION OF THE RELATED DISEASES.	2022

10  4803  24 OBESITY AND MALE INFERTILITY. THE WORLDWIDE PREVALENCE OF OBESITY IS INCREASING AMONG BOTH SEXES, WITH ASSOCIATED IMPACTS ON CHRONIC HEALTH AND MEDICAL COMORBIDITIES. SIMILARLY, THE EFFECTS OF OBESITY ON REPRODUCTIVE HEALTH ARE INCREASINGLY BEING RECOGNIZED. ADIPOSITY IS ASSOCIATED WITH REDUCED FERTILITY IN MEN, WITH A COMPLEX AND MULTIFACTORIAL ETIOLOGY. THE REPORTED EFFECTS OF OBESITY ON SEMEN PARAMETERS AND IMPAIRED FERTILITY ARE CONTRASTING, WITH SOME STUDIES SHOWING A CLEAR REDUCTION IN REPRODUCTIVE OUTCOMES ASSOCIATED WITH INCREASED BODY MASS INDEX, WHILE OTHERS DO NOT SHOW SUCH IMPACTS. THESE CONTROVERSIES MAY BE DUE TO THE COMPLEX PATHOPHYSIOLOGY AND INTERPLAY BETWEEN GONADOTROPINS AND END ORGANS, AS WELL AS GENETIC AND EPIGENETIC CHANGES AND OXIDATIVE STRESS ON MALE FERTILITY AND FUNCTION. THESE DIFFERENT ASPECTS HAVE LED TO HETEROGENEOUS PARTICIPANTS IN STUDIES AND VARYING IMPLICATIONS FOR ASSISTED REPRODUCTIVE OUTCOMES AS WELL AS OFFSPRING HEALTH. TREATMENT MODALITIES TO MANAGE OBESITY INCLUDE LIFESTYLE, MEDICAL, AND SURGICAL OPTIONS, WITH EMERGING AND EFFECTIVE MEDICAL TREATMENTS SHOWING PROMISE IN REPRODUCTIVE OUTCOMES.	2023

11   518  31 ASSOCIATIONS BETWEEN ANTIBIOTIC EXPOSURE DURING PREGNANCY, BIRTH WEIGHT AND ABERRANT METHYLATION AT IMPRINTED GENES AMONG OFFSPRING. OBJECTIVES: LOW BIRTH WEIGHT (LBW) HAS BEEN ASSOCIATED WITH COMMON ADULT-ONSET CHRONIC DISEASES, INCLUDING OBESITY, CARDIOVASCULAR DISEASE, TYPE II DIABETES AND SOME CANCERS. THE ETIOLOGY OF LBW IS MULTI-FACTORIAL. HOWEVER, RECENT EVIDENCE SUGGESTS EXPOSURE TO ANTIBIOTICS MAY ALSO INCREASE THE RISK OF LBW. THE MECHANISMS UNDERLYING THIS ASSOCIATION ARE UNKNOWN, ALTHOUGH EPIGENETIC MECHANISMS ARE HYPOTHESIZED. IN THIS STUDY, WE EVALUATED THE ASSOCIATION BETWEEN MATERNAL ANTIBIOTIC USE AND LBW AND EXAMINED THE POTENTIAL ROLE OF ALTERED DNA METHYLATION THAT CONTROLS GROWTH REGULATORY IMPRINTED GENES IN THESE ASSOCIATIONS. METHODS: BETWEEN 2009-2011, 397 PREGNANT WOMEN WERE ENROLLED AND FOLLOWED UNTIL DELIVERY. PRENATAL ANTIBIOTIC USE WAS ASCERTAINED THROUGH MATERNAL SELF-REPORT. IMPRINTED GENES METHYLATION LEVELS WERE MEASURED AT DIFFERENTIALLY METHYLATED REGIONS (DMRS) USING BISULFITE PYROSEQUENCING. GENERALIZED LINEAR MODELS WERE USED TO EXAMINE ASSOCIATIONS AMONG ANTIBIOTIC USE, BIRTH WEIGHT AND DMR METHYLATION FRACTIONS. RESULTS: AFTER ADJUSTING FOR INFANT GENDER, RACE/ETHNICITY, MATERNAL BODY MASS INDEX, DELIVERY ROUTE, GESTATIONAL WEIGHT GAIN, GESTATIONAL AGE AT DELIVERY, FOLIC ACID INTAKE, PHYSICAL ACTIVITY, MATERNAL SMOKING AND PARITY, ANTIBIOTIC USE DURING PREGNANCY WAS ASSOCIATED WITH 138 G LOWER BIRTH WEIGHT COMPARED WITH NON-ANTIBIOTIC USE (BETA-COEFFICIENT=-132.99, S.E.=50.70, P=0.008). THESE ASSOCIATIONS WERE STRONGEST IN NEWBORNS OF WOMEN WHO REPORTED ANTIBIOTIC USE OTHER THAN PENICILLINS (BETA-COEFFICIENT=-135.57, S.E.=57.38, P=0.02). METHYLATION AT FIVE DMRS, IGF2 (P=0.05), H19 (P=0.15), PLAGL1 (P=0.01), MEG3 (P=0.006) AND PEG3 (P=0.08), WAS ASSOCIATED WITH MATERNAL ANTIBIOTIC USE; AMONG THESE, ONLY METHYLATION AT THE PLAGL1 DMR WAS ALSO ASSOCIATED WITH BIRTH WEIGHT. CONCLUSION: WE REPORT AN INVERSE ASSOCIATION BETWEEN IN UTERO EXPOSURE TO ANTIBIOTICS AND LOWER INFANT BIRTH WEIGHT AND PROVIDE THE FIRST EMPIRICAL EVIDENCE SUPPORTING IMPRINTED GENE PLASTICITY IN THESE ASSOCIATIONS.	2013

12  4010  28 LOW MATERNAL ADHERENCE TO A MEDITERRANEAN DIET IS ASSOCIATED WITH INCREASE IN METHYLATION AT THE MEG3-IG DIFFERENTIALLY METHYLATED REGION IN FEMALE INFANTS. DIET IS DICTATED BY THE SURROUNDING ENVIRONMENT, AS FOOD ACCESS AND AVAILABILITY MAY CHANGE DEPENDING ON WHERE ONE LIVES. MATERNAL DIET DURING PREGNANCY IS AN IMPORTANT PART OF THE IN UTERO ENVIRONMENT, AND MAY AFFECT THE EPIGENOME. STUDIES LOOKING AT OVERALL DIET PATTERN IN RELATION TO DNA METHYLATION HAVE BEEN LACKING. THE MEDITERRANEAN DIET IS KNOWN FOR ITS HEALTH BENEFITS, INCLUDING DECREASED INFLAMMATION, WEIGHT LOSS, AND MANAGEMENT OF CHRONIC DISEASES. THIS STUDY ASSESSES THE ASSOCIATION BETWEEN MATERNAL ADHERENCE TO A MEDITERRANEAN DIET PATTERN DURING PREGNANCY AND INFANT DNA METHYLATION AT BIRTH. MEDITERRANEAN DIET ADHERENCE IN EARLY PREGNANCY WAS MEASURED IN 390 WOMEN ENROLLED IN THE NEWBORN EPIGENETIC STUDY, AND DNA METHYLATION WAS ASSESSED IN THEIR INFANTS AT BIRTH. MULTINOMIAL LOGISTIC REGRESSION WAS USED TO ASSESS THE ASSOCIATION BETWEEN ADHERENCE TO A MEDITERRANEAN DIET AND INFANT METHYLATION AT THE MEG3, MEG3-IG, PLEIOMORPHIC ADENOMA GENE-LIKE 1, INSULIN-LIKE GROWTH FACTOR 2 GENE, H19, MESODERM-SPECIFIC TRANSCRIPT, NEURONATIN, PATERNALLY EXPRESSED GENE 3, SARCOGLYCAN AND PATERNALLY EXPRESSED GENE 10 REGIONS, MEASURED BY PYROSEQUENCING. INFANTS OF MOTHERS WITH A LOW ADHERENCE TO A MEDITERRANEAN DIET HAD A GREATER ODDS OF HYPO-METHYLATION AT THE MEG3-IG DIFFERENTIALLY METHYLATED REGION (DMR). SEX-STRATIFIED MODELS SHOWED THAT THIS ASSOCIATION WAS PRESENT IN GIRLS ONLY. THIS STUDY PROVIDES EARLY EVIDENCE ON THE ASSOCIATION BETWEEN OVERALL DIET PATTERN AND METHYLATION AT THE 9 DMRS INCLUDED IN THIS STUDY, AND SUGGESTS THAT MATERNAL DIET CAN HAVE A SEX-SPECIFIC IMPACT ON INFANT DNA METHYLATION AT SPECIFIC IMPRINTED DMRS.	2017

13  5786  27 SPORT AND MALE SEXUALITY. THE RELATIONSHIPS BETWEEN SPORT AND SEXUALITY IN MALES ARE OF GREAT SOCIAL AND CLINICAL INTEREST, BECAUSE OF SPORTS AND MOTOR ACTIVITIES THAT HIGHLY PROMOTE SOCIAL AND SEXUAL RELATIONSHIPS. EVEN IF FEW LITERATURE EXIST, TWO MAIN QUESTIONS SHOULD BE TAKEN INTO ACCOUNT: WHETHER AND HOW PHYSICAL EXERCISE AND SPORT POSITIVELY OR NEGATIVELY INFLUENCE SEXUAL HEALTH AND BEHAVIOR AND/OR WHETHER AND HOW SEXUAL BEHAVIOR MAY AFFECT A SUB-SEQUENT SPORT PERFORMANCE. PHYSICAL EXERCISE AND SPORT PER SE CAN INFLUENCE, POSITIVELY OR NEGATIVELY, THE HYPOTHALAMIC-PITUITARY-TESTICULAR AXIS FUNCTION AND, CONSEQUENTLY, THE INDIVIDUAL'S REPRODUCTIVE AND/OR SEXUAL HEALTH. THIS DEPENDS ON INDIVIDUAL FACTORS SUCH AS GENETIC AND EPIGENETIC ONES AND ON DIFFERENT VARIABLES INVOLVED IN THE PRACTICE OF SPORT ACTIVITIES (TYPE OF SPORT, INTENSITY AND DURATION OF TRAINING, DOPING AND DRUG USE AND ABUSE, NUTRITION, SUPPLEMENTS, PSYCHOLOGICAL STRESS, ALLOSTATIC LOAD, ETC.). IF WELL CONDUCTED, MOTOR AND SPORT ACTIVITIES COULD HAVE BENEFICIAL EFFECTS ON SEXUAL HEALTH IN MALES. AMONG DIFFERENT LIFESTYLE CHANGES, INFLUENCING SEXUAL HEALTH, REGULAR PHYSICAL ACTIVITY IS FUNDAMENTAL TO ANTAGONIZE THE ONSET OF ERECTILE DYSFUNCTION (ED). HOWEVER, COMPETITIVE SPORT CAN LEAD BOTH REPRODUCTIVE AND/OR SEXUAL TRACT DAMAGES AND DYSFUNCTIONS, TRANSIENT (GENITAL PAIN, HYPOESTHESIA OF THE GENITALIA, HYPOGONADISM, DE, ALTERED SEXUAL DRIVE, ETC.) OR PERMANENT (HYPOGONADISM, DE, ETC.), BY ACTING DIRECTLY (TRAUMAS OF THE EXTERNAL GENITALIA, SADDLE-RELATED DISORDERS IN CYCLISTS, ETC.) OR INDIRECTLY (EXERCISE-RELATED HYPOGONADISM, DRUG ABUSE, DOPING, STRESS, ETC.). SEXUAL ACTIVITIES SHORTLY PERFORMED BEFORE A SPORT COMPETITION COULD DIFFERENTLY INFLUENCE SPORT PERFORMANCE. DUE TO THE FEW EXISTING DATA, IT IS ADVISABLE TO AVOID AN ABSOLUTE PRE-COMPETITION SEXUAL ABSTINENCE.	2017

14  4066  31 MATERNAL AND PATERNAL PERICONCEPTIONAL NUTRITION AS AN INDICATOR OF OFFSPRING METABOLIC SYNDROME RISK IN LATER LIFE THROUGH EPIGENETIC IMPRINTING: A SYSTEMATIC REVIEW. AIMS: THIS REVIEW EXAMINED WHETHER MATERNAL AND PATERNAL PERICONCEPTIONAL NUTRITION EFFECTS AN OFFSPRING'S LIKELIHOOD OF DEVELOPING CHRONIC METABOLIC RELATED CONDITIONS DUE TO EPIGENETIC IMPRINTING. METHODS: A LITERATURE SEARCH WAS CONDUCTED IN MULTIPLE SCIENCE DATABASES AND LIMITED TO STUDIES PUBLISHED AFTER 2012, IN ENGLISH LANGUAGE AND PEER REVIEWED. THE DATA FROM SELECTED ARTICLES WERE EXTRACTED AND A QUALITATIVE APPROACH WAS EMPLOYED DUE TO HETEROGENEITY OF RESULTS. RESULTS: NEWBORNS FROM OBESE FATHERS SHOWED ALTERED METHYLATION OVERALL AND SIGNIFICANT HYPOMETHYLATION AT THE INSULIN-LIKE GROWTH FACTOR 2 (IGF2) GENE. HIGH MATERNAL PRE-PREGNANCY BODY MASS INDEX (BMI) WAS ASSOCIATED WITH ALTERED OFFSPRING DNA METHYLATION LEVELS AND GESTATIONAL DIABETES MELLITUS INDUCED SIGNIFICANTLY INCREASED METHYLATION LEVELS IN OFFSPRING. GESTATIONAL WEIGHT GAIN WAS NOT ASSOCIATED WITH DIFFERENTIALLY METHYLATED CORD BLOOD. BIRTH WEIGHT WAS HIGHER IN OFFSPRING EXPOSED TO FAMINE IN EARLY GESTATION. OFFSPRING BORN POST MATERNAL BARIATRIC SURGERY SHOWED A LOWER PERCENTAGE OF BODY FAT AND IMPROVED FASTING INSULIN LEVELS COMPARED TO SIBLINGS BORN PRE-MATERNAL BARIATRIC SURGERY. CONCLUSIONS: THE AVAILABLE EVIDENCE SUGGESTS THAT POOR MATERNAL AND PATERNAL PERICONCEPTIONAL NUTRITION CAN INCREASE THE RISK OF METABOLIC SYNDROME IN OFFSPRING, THROUGH EPIGENETIC IMPRINTING. POTENTIAL PARENTS SHOULD BE ADVISED THAT MAINTAINING A HEALTHY DIET AND BMI IS LIKELY TO REDUCE THE RISK OF METABOLIC SYNDROME IN OFFSPRING.	2017

15  4691  32 NEWBORNS OF OBESE PARENTS HAVE ALTERED DNA METHYLATION PATTERNS AT IMPRINTED GENES. BACKGROUND: SEVERAL EPIDEMIOLOGIC STUDIES HAVE DEMONSTRATED ASSOCIATIONS BETWEEN PERICONCEPTIONAL ENVIRONMENTAL EXPOSURES AND HEALTH STATUS OF THE OFFSPRING IN LATER LIFE. ALTHOUGH THESE ENVIRONMENTALLY RELATED EFFECTS HAVE BEEN ATTRIBUTED TO EPIGENETIC CHANGES, SUCH AS DNA METHYLATION SHIFTS AT IMPRINTED GENES, LITTLE IS KNOWN ABOUT THE POTENTIAL EFFECTS OF MATERNAL AND PATERNAL PRECONCEPTIONAL OVERNUTRITION OR OBESITY. OBJECTIVE: WE EXAMINED PARENTAL PRECONCEPTIONAL OBESITY IN RELATION TO DNA METHYLATION PROFILES AT MULTIPLE HUMAN IMPRINTED GENES IMPORTANT IN NORMAL GROWTH AND DEVELOPMENT, SUCH AS: MATERNALLY EXPRESSED GENE 3 (MEG3), MESODERM-SPECIFIC TRANSCRIPT (MEST), PATERNALLY EXPRESSED GENE 3 (PEG3), PLEIOMORPHIC ADENOMA GENE-LIKE 1 (PLAGL1), EPSILON SARCOGLYCAN AND PATERNALLY EXPRESSED GENE 10 (SGCE/PEG10) AND NEURONATIN (NNAT). METHODS: WE MEASURED METHYLATION PERCENTAGES AT THE DIFFERENTIALLY METHYLATED REGIONS (DMRS) BY BISULFITE PYROSEQUENCING IN DNA EXTRACTED FROM UMBILICAL CORD BLOOD LEUKOCYTES OF 92 NEWBORNS. PRECONCEPTIONAL OBESITY, DEFINED AS BMI ?30 KG M(-2), WAS ASCERTAINED THROUGH STANDARDIZED QUESTIONNAIRES. RESULTS: AFTER ADJUSTING FOR POTENTIAL CONFOUNDERS AND CLUSTER EFFECTS, PATERNAL OBESITY WAS SIGNIFICANTLY ASSOCIATED WITH LOWER METHYLATION LEVELS AT THE MEST (BETA=-2.57; S.E.=0.95; P=0.008), PEG3 (BETA=-1.71; S.E.=0.61; P=0.005) AND NNAT (BETA=-3.59; S.E.=1.76; P=0.04) DMRS. CHANGES RELATED TO MATERNAL OBESITY DETECTED AT OTHER LOCI WERE AS FOLLOWS: BETA-COEFFICIENT WAS +2.58 (S.E.=1.00; P=0.01) AT THE PLAGL1 DMR AND -3.42 (S.E.=1.69; P=0.04) AT THE MEG3 DMR. CONCLUSION: WE FOUND ALTERED METHYLATION OUTCOMES AT MULTIPLE IMPRINT REGULATORY REGIONS IN CHILDREN BORN TO OBESE PARENTS, COMPARED WITH CHILDREN BORN TO NON-OBESE PARENTS. IN SPITE OF THE SMALL SAMPLE SIZE, OUR DATA SUGGEST A PRECONCEPTIONAL INFLUENCE OF PARENTAL LIFE-STYLE OR OVERNUTRITION ON THE (RE)PROGRAMMING OF IMPRINT MARKS DURING GAMETOGENESIS AND EARLY DEVELOPMENT. MORE SPECIFICALLY, THE SIGNIFICANT AND INDEPENDENT ASSOCIATION BETWEEN PATERNAL OBESITY AND THE OFFSPRING'S METHYLATION STATUS SUGGESTS THE SUSCEPTIBILITY OF THE DEVELOPING SPERM FOR ENVIRONMENTAL INSULTS. THE ACQUIRED IMPRINT INSTABILITY MAY BE CARRIED ONTO THE NEXT GENERATION AND INCREASE THE RISK FOR CHRONIC DISEASES IN ADULTHOOD.	2015

16  5584  23 ROLE OF OBESITY IN FEMALE REPRODUCTION. CONTEMPORARY SCIENTISTS NEED NO "P VALUE" AND "RELATIVE RISK" STATISTICS TO BE EXQUISITELY AWARE OF THE INCREASING PREVALENCE OF OBESITY AND COMPLICATIONS POSED BY OBESITY. IT IS NOW WELL RECOGNIZED THAT OBESITY IS STRONGLY ASSOCIATED WITH TYPE 2 DIABETES, HYPERTENSION, VASCULAR DISEASE, TUMORS AND REPRODUCTIVE DISORDERS. OBESE WOMEN SHOW LOWER LEVELS OF GONADOTROPIN HORMONES, REDUCED FECUNDITY, HIGHER MISCARRIAGE RATES AND POORER OUTCOMES OF IN VITRO FERTILIZATION, REVEALING THAT OBESITY AFFECTS FEMALE REPRODUCTION. IN ADDITION, ADIPOSE TISSUE CONTAINS SPECIAL IMMUNE CELLS AND OBESITY-INDUCED INFLAMMATION IS A CHRONIC, LOW-GRADE INFLAMMATORY RESPONSE. HEREIN, WE MAINLY REVIEW DETRIMENTAL INFLUENCES OF OBESITY IN THE COMPLETE PROCESS OF FEMALE REPRODUCTION, INCLUDING HYPOTHALAMIC-PITUITARY-OVARIAN AXIS, OOCYTE MATURATION, EMBRYO AND FETAL DEVELOPMENT. IN THE LATTER PART, WE VIEW OBESITY-INDUCED INFLAMMATION AND DISCUSS RELATED EPIGENETIC IMPACT ON FEMALE REPRODUCTION.	2023

17  5395  34 REDUCED EPIGENETIC AGE IN OLDER ADULTS WITH HIGH SENSE OF PURPOSE IN LIFE. PSYCHOSOCIAL RISK FACTORS HAVE BEEN LINKED WITH ACCELERATED EPIGENETIC AGING, BUT LITTLE IS KNOWN ABOUT WHETHER PSYCHOSOCIAL RESILIENCE FACTORS (EG, SENSE OF PURPOSE IN LIFE) MIGHT REDUCE EPIGENETIC AGE ACCELERATION. IN THIS STUDY, WE TESTED IF OLDER ADULTS WHO EXPERIENCE HIGH LEVELS OF PURPOSE MIGHT SHOW REDUCED EPIGENETIC AGE ACCELERATION. WE EVALUATED THE RELATIONSHIP BETWEEN PURPOSE AND EPIGENETIC AGE ACCELERATION AS MEASURED BY 13 DNA METHYLATION (DNAM) "EPIGENETIC CLOCKS" ASSESSED IN 1 572 OLDER ADULTS FROM THE HEALTH AND RETIREMENT STUDY (MEAN AGE 70 YEARS). WE QUANTIFIED THE TOTAL ASSOCIATION BETWEEN PURPOSE AND DNAM AGE ACCELERATION AS WELL AS THE EXTENT TO WHICH THAT TOTAL ASSOCIATION MIGHT BE ATTRIBUTABLE TO DEMOGRAPHIC FACTORS, CHRONIC DISEASE, OTHER PSYCHOSOCIAL VARIABLES (EG, POSITIVE AFFECT), AND HEALTH-RELATED BEHAVIORS (HEAVY DRINKING, SMOKING, PHYSICAL ACTIVITY, AND BODY MASS INDEX [BMI]). PURPOSE IN LIFE WAS ASSOCIATED WITH REDUCED EPIGENETIC AGE ACCELERATION ACROSS 4 "SECOND-GENERATION" DNAM CLOCKS OPTIMIZED FOR PREDICTING HEALTH AND LONGEVITY (FALSE DISCOVERY RATE [FDR] Q < 0.0001: PHENOAGE, GRIMAGE, ZHANG EPIGENETIC MORTALITY INDEX; FDR Q < 0.05: DUNEDINPOAM). THESE ASSOCIATIONS WERE INDEPENDENT OF DEMOGRAPHIC AND PSYCHOSOCIAL FACTORS, BUT SUBSTANTIALLY ATTENUATED AFTER ADJUSTING FOR HEALTH-RELATED BEHAVIORS (DRINKING, SMOKING, PHYSICAL ACTIVITY, AND BMI). PURPOSE SHOWED NO SIGNIFICANT ASSOCIATION WITH 9 "FIRST-GENERATION" DNAM EPIGENETIC CLOCKS TRAINED ON CHRONOLOGICAL AGE. OLDER ADULTS WITH GREATER PURPOSE IN LIFE SHOW "YOUNGER" DNAM EPIGENETIC AGE ACCELERATION. THESE RESULTS MAY BE DUE IN PART TO ASSOCIATED DIFFERENCES IN HEALTH-RELATED BEHAVIORS. RESULTS SUGGEST NEW OPPORTUNITIES TO REDUCE BIOLOGICAL AGE ACCELERATION BY ENHANCING PURPOSE AND ITS BEHAVIORAL SEQUELAE IN LATE ADULTHOOD.	2023

18  4942  28 PATERNAL OBESITY: HOW BAD IS IT FOR SPERM QUALITY AND PROGENY HEALTH? THERE IS SUBSTANTIAL EVIDENCE THAT PATERNAL OBESITY IS ASSOCIATED NOT ONLY WITH AN INCREASED INCIDENCE OF INFERTILITY, BUT ALSO WITH AN INCREASED RISK OF METABOLIC DISTURBANCE IN ADULT OFFSPRING. APPARENTLY, SEVERAL MECHANISMS MAY CONTRIBUTE TO THE SPERM QUALITY ALTERATIONS ASSOCIATED WITH PATERNAL OBESITY, SUCH AS PHYSIOLOGICAL/HORMONAL ALTERATIONS, OXIDATIVE STRESS, AND EPIGENETIC ALTERATIONS. ALONG THESE LINES, MODIFICATIONS OF HORMONAL PROFILES NAMELY REDUCED ANDROGEN LEVELS AND ELEVATED ESTROGEN LEVELS, WERE FOUND ASSOCIATED WITH LOWER SPERM CONCENTRATION AND SEMINAL VOLUME. ADDITIONALLY, OXIDATIVE STRESS IN TESTIS MAY INDUCE AN INCREASE OF THE PERCENTAGE OF SPERM WITH DNA FRAGMENTATION. THE LATTER, RELATE TO OTHER PECULIARITIES SUCH AS ALTERATION OF THE EMBRYONIC DEVELOPMENT, INCREASED RISK OF MISCARRIAGE, AND DEVELOPMENT OF CHRONIC MORBIDITY IN THE OFFSPRING, INCLUDING CHILDHOOD CANCERS. UNDOUBTEDLY, EPIGENETIC ALTERATIONS (IE, DNA METHYLATION, CHROMATIN MODIFICATIONS, AND SMALL RNA DEREGULATION) OF SPERM RELATED TO PATERNAL OBESITY AND THEIR CONSEQUENCES ON THE PROGENY ARE POORLY UNDERSTOOD DETERMINANTS OF PATERNAL OBESITY-INDUCED TRANSMISSION. IN THIS REVIEW, WE SUMMARIZE AND DISCUSS THE DATA AVAILABLE IN THE LITERATURE REGARDING THE BIOLOGICAL, PHYSIOLOGICAL, AND MOLECULAR CONSEQUENCES OF PATERNAL OBESITY ON MALE FERTILITY POTENTIAL AND

19   846  36 CHILDHOOD EXPOSURE TO AMBIENT POLYCYCLIC AROMATIC HYDROCARBONS IS LINKED TO EPIGENETIC MODIFICATIONS AND IMPAIRED SYSTEMIC IMMUNITY IN T CELLS. BACKGROUND: EVIDENCE SUGGESTS THAT EXPOSURE TO POLYCYCLIC AROMATIC HYDROCARBONS (PAHS) INCREASES ATOPY; IT IS UNCLEAR HOW PAH EXPOSURE IS LINKED TO INCREASED SEVERITY OF ATOPIC DISEASES. OBJECTIVE: WE HYPOTHESIZED THAT AMBIENT PAH EXPOSURE IS LINKED TO IMPAIRMENT OF IMMUNITY IN ATOPIC CHILDREN (DEFINED AS CHILDREN WITH ASTHMA AND/OR ALLERGIC RHINITIS) FROM FRESNO, CALIFORNIA, AN AREA WITH ELEVATED AMBIENT PAHS. METHODS: WE RECRUITED 256 SUBJECTS FROM FRESNO, CA. AMBIENT PAH CONCENTRATIONS (NG/M(3) ) WERE MEASURED USING A SPATIAL-TEMPORAL REGRESSION MODEL OVER MULTIPLE TIME PERIODS. ASTHMA DIAGNOSIS WAS DETERMINED BY CURRENT NHLBI CRITERIA. PHENOTYPING AND FUNCTIONAL IMMUNE MEASUREMENTS WERE PERFORMED FROM ISOLATED CELLS. FOR EPIGENETIC MEASUREMENTS, DNA WAS ISOLATED AND PYROSEQUENCED. RESULTS: WE SHOW THAT HIGHER AVERAGE PAH EXPOSURE WAS SIGNIFICANTLY ASSOCIATED WITH IMPAIRED TREG FUNCTION AND INCREASED METHYLATION IN THE FORKHEAD BOX PROTEIN 3 (FOXP3) LOCUS (P < 0.05), CONDITIONAL ON ATOPIC STATUS. THESE EPIGENETIC MODIFICATIONS WERE SIGNIFICANTLY LINKED TO DIFFERENTIAL PROTEIN EXPRESSION OF FOXP3 (P < 0.001). METHYLATION WAS ASSOCIATED WITH CELLULAR FUNCTIONAL CHANGES, SPECIFICALLY TREG DYSFUNCTION, AND AN INCREASE IN TOTAL PLASMA IGE LEVELS. PROTEIN EXPRESSION OF IL-10 DECREASED AND IFN-GAMMA INCREASED AS THE EXTENT OF PAH EXPOSURE INCREASED. THE STRENGTH OF THE ASSOCIATIONS GENERALLY INCREASED AS THE TIME WINDOW FOR AVERAGE PAH EXPOSURE INCREASED FROM 24 HR TO 1 YEAR, SUGGESTING MORE OF A CHRONIC RESPONSE. SIGNIFICANT ASSOCIATIONS WITH CHRONIC PAH EXPOSURE AND IMMUNE OUTCOMES WERE ALSO OBSERVED IN SUBJECTS WITH ALLERGIC RHINITIS. CONCLUSIONS AND CLINICAL RELEVANCE: COLLECTIVELY, THESE RESULTS DEMONSTRATE THAT INCREASED AMBIENT PAH EXPOSURE IS ASSOCIATED WITH IMPAIRED SYSTEMIC IMMUNITY AND EPIGENETIC MODIFICATIONS IN A KEY LOCUS INVOLVED IN ATOPY: FOXP3, WITH A HIGHER IMPACT ON ATOPIC CHILDREN. THE RESULTS SUGGEST THAT INCREASED ATOPIC CLINICAL SYMPTOMS IN CHILDREN COULD BE LINKED TO INCREASED PAH EXPOSURE IN AIR POLLUTION.	2015

20  5728  25 SLEEP QUALITY AND METHYLATION STATUS OF SELECTED TUMOR SUPPRESSOR GENES AMONG NURSES AND MIDWIVES. CHRONIC SLEEP RESTRICTION MAY AFFECT METABOLISM, HORMONE SECRETION PATTERNS AND INFLAMMATORY RESPONSES. LIMITED REPORTS SUGGEST ALSO EPIGENETIC EFFECTS, SUCH AS CHANGES IN DNA METHYLATION PROFILES. THE STUDY AIMS TO ASSESS THE POTENTIAL ASSOCIATION BETWEEN POOR SLEEP QUALITY OR SLEEP DURATION AND THE LEVELS OF 5-METHYLCYTOSINE IN THE PROMOTER REGIONS OF SELECTED TUMOR SUPPRESSOR GENES. A CROSS-SECTIONAL STUDY WAS CONDUCTED ON 710 NURSES AND MIDWIVES AGED 40-60 YEARS. DATA FROM INTERVIEWS REGARDING SLEEP HABITS AND POTENTIAL CONFOUNDERS WERE USED. THE METHYLATION STATUS OF TUMOR SUPPRESSOR GENES WAS DETERMINED VIA QMSP REACTIONS USING DNA SAMPLES DERIVED FROM LEUCOCYTES. NO SIGNIFICANT FINDINGS WERE OBSERVED IN THE TOTAL STUDY POPULATION OR IN THE TWO SUBGROUPS OF WOMEN STRATIFIED BY THE CURRENT SYSTEM OF WORK. A BORDERLINE SIGNIFICANCE ASSOCIATION WAS OBSERVED BETWEEN A SHORTER DURATION OF SLEEP AND AN INCREASED METHYLATION LEVEL IN CDKN2A AMONG DAY WORKING NURSES AND MIDWIVES. FURTHER STUDIES ARE WARRANTED TO EXPLORE THIS UNDER-INVESTIGATED TOPIC.	2018
