1   524 133 ASSOCIATIONS OF BDNF GENOTYPE AND PROMOTER METHYLATION WITH ACUTE AND LONG-TERM STROKE OUTCOMES IN AN EAST ASIAN COHORT. BACKGROUND: BRAIN DERIVED NEUROTROPHIC FACTOR (BDNF) HAS BEEN SHOWN TO PLAY AN IMPORTANT ROLE IN POSTSTROKE RECOVERY. BDNF SECRETION IS INFLUENCED BY GENETIC AND EPIGENETIC PROFILES. THIS STUDY AIMED TO INVESTIGATE WHETHER BDNF VAL66MET POLYMORPHISM AND PROMOTER METHYLATION STATUS WERE ASSOCIATED WITH OUTCOMES AT TWO WEEKS AND ONE YEAR AFTER STROKE. METHODS AND FINDINGS: A TOTAL OF 286 PATIENTS WERE EVALUATED AT THE TIME OF ADMISSION AND TWO WEEKS AFTER STROKE, AND 222 (78%) WERE FOLLOWED ONE YEAR LATER IN ORDER TO EVALUATE CONSEQUENCES OF STROKE AT BOTH ACUTE AND CHRONIC STAGES. STROKE OUTCOMES WERE DICHOTOMISED INTO GOOD AND POOR BY THE MODIFIED RANKIN SCALE. STROKE SEVERITY (NATIONAL INSTITUTES OF HEALTH STROKE SCALE), PHYSICAL DISABILITY (BARTHEL INDEX), AND COGNITIVE FUNCTION (MINI-MENTAL STATE EXAMINATION) WERE MEASURED. ASSOCIATIONS OF BDNF GENOTYPE AND METHYLATION STATUS ON STROKE OUTCOMES AND ASSESSMENT SCALE SCORES WERE INVESTIGATED USING LOGISTIC REGRESSION, REPEATED MEASURES ANOVA AND PARTIAL CORRELATION TESTS. BDNF VAL66MET POLYMORPHISM WAS INDEPENDENTLY ASSOCIATED WITH POOR OUTCOME AT 2 WEEKS AND AT 1 YEAR, AND WITH WORSENING PHYSICAL DISABILITY AND COGNITIVE FUNCTION OVER THAT PERIOD. HIGHER BDNF PROMOTER METHYLATION STATUS WAS INDEPENDENTLY ASSOCIATED WITH WORSE OUTCOMES AT 1 YEAR, AND WITH THE WORSENING OF PHYSICAL DISABILITY AND COGNITIVE FUNCTION. NO SIGNIFICANT GENOTYPE-METHYLATION INTERACTIONS WERE FOUND. CONCLUSIONS: A ROLE FOR BDNF IN POSTSTROKE RECOVERY WAS SUPPORTED, AND CLINICAL UTILITY OF BDNF GENETIC AND EPIGENETIC PROFILE AS PROGNOSTIC BIOMARKERS AND A TARGET FOR DRUG DEVELOPMENT WAS SUGGESTED.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
2  6713  28 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	

3  6545  27 TRANSCRIPTOMIC AND EPIGENETIC CHANGES IN THE HYPOTHALAMUS ARE INVOLVED IN AN INCREASED SUSCEPTIBILITY TO A HIGH-FAT-SUCROSE DIET IN PRENATALLY STRESSED FEMALE RATS. DISTURBANCES IN THE PRENATAL PERIOD ARE LINKED TO METABOLIC DISORDERS IN ADULTHOOD, IMPLYING THE HYPOTHALAMIC SYSTEMS OF APPETITE AND ENERGY BALANCE REGULATION. IN ORDER TO ANALYZE THE CENTRAL EFFECTS OF A HIGH-FAT-SUCROSE (HFS) DIET IN PRENATALLY STRESSED (PNS) FEMALE ADULT RATS, WISTAR DAMS WERE EXPOSED TO CHRONIC-MILD-STRESS DURING THE THIRD WEEK OF GESTATION AND WERE THEN COMPARED WITH UNSTRESSED CONTROLS. ADULT FEMALE OFFSPRING WERE FED A CHOW OR HFS DIET FOR 10 WEEKS. CHANGES IN BODY WEIGHT, ADIPOSITY AS WELL AS EXPRESSION AND METHYLATION LEVELS OF SELECTED HYPOTHALAMIC GENES WERE ANALYZED. PNS INDUCED LOWER BIRTHWEIGHT AND BODY LENGTH WITH NO CHANGES IN BODY FAT MASS. AFTER THE HFS DIET, THE EXPECTED OVERWEIGHT MODEL WAS OBSERVED ACCOMPANIED BY HIGHER ADIPOSITY AND INSULIN RESISTANCE, WHICH WAS WORSENED BY PNS. THE STRESS MODEL INDUCED HIGHER ENERGY INTAKE IN ADULTHOOD. HYPOTHALAMIC GENE EXPRESSION ANALYSIS REVEALED THAT THE HFS DIET DECREASED SLC6A3 (DOPAMINE ACTIVE TRANSPORTER), NPY (NEUROPEPTIDE Y) AND IR (INSULIN RECEPTOR) AND INCREASED POMC (PRO-OPIOMELANOCORTIN). HYPOTHALAMIC DNA METHYLATION LEVELS IN THE PROMOTER REGION OF SLC6A3 REVEALED THAT SLC6A3 WAS HYPERMETHYLATED BY THE HFS DIET IN CPG SITE -53 BP TO THE TRANSCRIPTION START SITE. HFS DIET ALSO HYPERMETHYLATED CPG SITE -167 BP OF THE POMC PROMOTER ONLY IN NONSTRESSED ANIMALS. NO CORRELATIONS WERE FOUND BETWEEN GENE EXPRESSION AND DNA METHYLATION LEVELS. THESE RESULTS IMPLY THAT EARLY-LIFE STRESS IN FEMALES INCREASED PREDISPOSITION TO DIET-INDUCED OBESITY IN ADULTHOOD.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
4  5314  26 PSYCHOLOGICAL STRESS IN ASTHMA: REPERCUSSIONS ON EPIGENETICS-GENETICS, IMMUNE RESPONSES, AND PULMONARY FUNCTION IN THE PEDIATRIC POPULATION. IN THE ASSESSMENT OF CHILDHOOD ASTHMA, IDENTIFYING THE RISK FACTORS ASSOCIATED WITH EXACERBATIONS AND BROADENING THIS VIEW TO UNDERSTAND PSYCHOLOGICAL STRESS AND ITS REPERCUSSIONS ON THE INFLAMMATORY PROCESS OF ASTHMA ALLOW A DIFFERENT PERSPECTIVE ON THIS BIOPSYCHOSOCIAL DISEASE. PSYCHOLOGICAL STRESS, AS A RISK FACTOR FOR THE ONSET AND NONCONTROL OF ASTHMA, HAS BEEN INCREASINGLY EVALUATED FROM THE PERSPECTIVE OF THE REPERCUSSIONS ON THE BODY OF THE STIMULUS GENERATED IN THE HYPOTHALAMIC-PITUITARY AXIS AND ADRENAL GLANDS, WITH CORTISOL RELEASE AND IMMUNE SYSTEM ACTION. THESE PROCESSES TRIGGER CHANGES IN T HELPER 2 CELLS, WHICH POLARIZE ALLERGIC PROCESSES, AND DYSFUNCTIONS IN IMMUNE TOLERANCE MECHANISMS, WITH A DECREASE IN REGULATORY T CELLS. GENETIC AND EPIGENETIC CHANGES IN BETA(2)-ADRENERGIC AND GLUCOCORTICOID RECEPTORS, WITH DECREASED RESPONSE TO THESE DRUGS, WERE ALSO IDENTIFIED IN STUDIES, IN ADDITION TO CHANGES IN RESPIRATORY FUNCTION PATTERNS, WITH WORSENING OF OBSTRUCTION AND INFLAMMATION IDENTIFIED VIA DECREASED FORCED EXPIRATORY VOLUME IN ONE SECOND AND INCREASED EXHALED INFLAMMATORY GASES IN ALLERGIC ASTHMA. THEREFORE, THE PRESENT REVIEW SOUGHT TO IDENTIFY STUDIES ON THE EFFECT OF PERSONAL AND PARENTAL ACUTE OR CHRONIC PSYCHOLOGICAL STRESS, EMPHASIZING THE REPERCUSSIONS ON GENETICS, EPIGENETICS, AND IMMUNE AND PULMONARY FUNCTIONAL AND INFLAMMATORY RESPONSES IN THE PEDIATRIC POPULATION.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
5   380  30 AN EPIGENETIC PERSPECTIVE ON LIFESTYLE MEDICINE FOR DEPRESSION: IMPLICATIONS FOR PRIMARY CARE PRACTICE. DEPRESSION IS THE MOST COMMON PRESENTING MENTAL HEALTH DISORDER IN PRIMARY CARE. IT IS ALSO A MAJOR CONTRIBUTOR TO SOMATIC COMPLAINTS, WORSENING OF CHRONIC MEDICAL CONDITIONS, POOR QUALITY OF LIFE, AND SUICIDE. CURRENT PHARMACOLOGIC AND PSYCHOTHERAPEUTIC APPROACHES AVERT LESS THAN HALF OF DEPRESSION'S CUMULATIVE BURDEN ON SOCIETY. HOWEVER, THERE IS A GROWING BODY OF RESEARCH DESCRIBING BOTH HOW MALADAPTIVE LIFESTYLE CHOICES CONTRIBUTE TO THE DEVELOPMENT AND WORSENING OF DEPRESSION AND HOW LIFESTYLE-ORIENTED MEDICAL INTERVENTIONS CAN REDUCE THE INCIDENCE AND SEVERITY OF DEPRESSION. THIS RESEARCH, LARGELY DERIVED FROM AN EMERGING FIELD CALLED EPIGENETICS, ELUCIDATES THE INTERACTIONS BETWEEN OUR LIFESTYLE CHOICES AND THOSE EPIGENETIC FACTORS WHICH MEDIATE OUR TENDENCIES TOWARD EITHER HEALTH, OR THE ONSET, IF NOT WORSENING OF DISEASE. THE PRESENT REVIEW HIGHLIGHTS HOW LIFESTYLE CHOICES INVOLVING DIET, PHYSICAL ACTIVITY, SLEEP, SOCIAL RELATIONSHIPS, AND STRESS INFLUENCE EPIGENETIC PROCESSES POSITIVELY OR NEGATIVELY, AND THEREBY PLAY A SIGNIFICANT ROLE IN DETERMINING WHETHER ONE DOES OR DOES NOT SUFFER FROM DEPRESSION. THE AUTHORS PROPOSE THAT MEDICAL TRAINING PROGRAMS CONSIDER AND ADOPT LIFESTYLE MEDICINE ORIENTED INSTRUCTIONAL INITIATIVES THAT WILL ENABLE TOMORROW'S PRIMARY CARE PROVIDERS TO MORE EFFECTIVELY IDENTIFY AND THERAPEUTICALLY INTERVENE IN THE MALADAPTIVE CHOICES CONTRIBUTING TO THEIR PATIENTS' DEPRESSION.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
6  2147  45 EPIGENETIC MARKER OF TELOMERIC AGE IS ASSOCIATED WITH EXACERBATIONS AND HOSPITALIZATIONS IN CHRONIC OBSTRUCTIVE PULMONARY DISEASE. BACKGROUND: CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD) IS AN AGE-RELATED CONDITION THAT HAS BEEN ASSOCIATED WITH EARLY TELOMERE ATTRITION; THE CLINICAL IMPLICATIONS OF TELOMERE SHORTENING IN COPD ARE NOT WELL KNOWN. IN THIS STUDY WE AIMED TO DETERMINE THE RELATIONSHIP OF THE EPIGENETIC REGULATION OF TELOMERIC LENGTH IN PERIPHERAL BLOOD WITH THE RISK OF EXACERBATIONS AND HOSPITALIZATION IN PATIENTS WITH COPD. METHODS: BLOOD DNA METHYLATION PROFILES WERE OBTAINED FROM 292 PATIENTS WITH COPD ENROLLED IN THE PLACEBO ARM OF THE MACROLIDE AZITHROMYCIN TO PREVENT RAPID WORSENING OF SYMPTOMS ASSOCIATED WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE (MACRO) STUDY AND WHO WERE FOLLOWED FOR 1-YEAR. WE CALCULATED TELOMERE LENGTH BASED ON DNA METHYLATION MARKERS (DNAMTL) AND RELATED THIS BIOMARKER TO THE RISK OF EXACERBATION AND HOSPITALIZATION AND HEALTH STATUS (ST. GEORGE RESPIRATORY QUESTIONNAIRE [SGRQ]) SCORE OVER TIME USING A COX PROPORTIONAL HAZARDS MODEL. WE ALSO USED LINEAR MODELS TO INVESTIGATE THE ASSOCIATIONS OF DNAMTL WITH THE RATES OF EXACERBATION AND HOSPITALIZATION (ADJUSTED FOR CHRONOLOGICAL AGE, LUNG FUNCTION, RACE, SEX, SMOKING, BODY MASS INDEX AND CELL COMPOSITION). RESULTS: PARTICIPANTS WITH SHORT DNAMTL DEMONSTRATED INCREASED RISK OF EXACERBATION (P = 0.02) AND HOSPITALIZATION (P = 0.03) COMPARED TO THOSE WITH LONGER DNAMTL. DNAMTL AGE ACCELERATION WAS ASSOCIATED WITH HIGHER RATES OF EXACERBATION (P = 1.35 X 10(-04)) AND HOSPITALIZATION (P = 5.21 X 10(-03)) AND POOR HEALTH STATUS (LOWER SGRQ SCORES) INDEPENDENT OF CHRONOLOGICAL AGE (P = 0.03). CONCLUSION: TELOMERIC AGE BASED ON BLOOD DNA METHYLATION IS ASSOCIATED WITH COPD EXACERBATION AND HOSPITALIZATION AND THUS A PROMISING BIOMARKER FOR POOR OUTCOMES IN COPD.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
7    67  60 A LONGITUDINAL STUDY OF THE ASSOCIATIONS OF BDNF GENOTYPE AND METHYLATION WITH POSTSTROKE ANXIETY. BACKGROUND: ALTHOUGH THE PRECISE ETIOLOGY OF POSTSTROKE ANXIETY (PSA) HAS YET TO BE FULLY ELUCIDATED, IT IS KNOWN THAT BRAIN-DERIVED NEUROTROPHIC FACTOR (BDNF) IS IMPORTANT FOR NEURAL PLASTICITY AND LONG-TERM POTENTIATION, ASSOCIATED WITH THE PATHOPHYSIOLOGY OF ANXIETY. THE EXPRESSION OF BDNF IS REGULATED BY EPIGENETIC AND GENETIC PROFILES. THUS, WE INVESTIGATED THE ASSOCIATION BETWEEN BDNF METHYLATION STATUS AND PSA AT 2 WEEKS AND 1 YEAR AFTER STROKE WHILE ACCOUNTING FOR INTERACTIONS WITH THE BDNF VAL66MET POLYMORPHISM. METHODS: THE BASELINE SAMPLE COMPRISED 286 PATIENTS WHO WERE ASSESSED AT 2 WEEKS AFTER STROKE; OF THESE PATIENTS, 222 (78%) WERE FOLLOWED UP WITH AT 1 YEAR AFTER STROKE. THE PRESENCE OF PSA WAS DETERMINED USING THE ANXIETY SUBSCALE OF THE HOSPITAL ANXIETY AND DEPRESSION SCALE (HADS), AND THE EFFECTS OF BDNF METHYLATION STATUS AND POLYMORPHISMS ON PSA STATUS WERE ASSESSED WITH MULTIVARIATE LOGISTIC REGRESSION MODELS. RESULTS: THE PREVALENCE OF PSA WAS SLIGHTLY LOWER (27 [9.4%]) AT BASELINE, AND 35 (15.8%) PATIENTS WERE IDENTIFIED AS HAVING PSA AT THE 1-YEAR FOLLOW-UP. STROKE PATIENTS WITH A HIGHER AVERAGE METHYLATION STATUS WERE MORE LIKELY TO HAVE PSA AT 1 YEAR. THE BDNF VAL66MET POLYMORPHISM WAS NOT INDEPENDENTLY ASSOCIATED WITH PSA DURING EITHER THE ACUTE OR CHRONIC PHASE AFTER STROKE, BUT THERE WAS A SIGNIFICANT INTERACTIVE EFFECT BETWEEN BDNF METHYLATION AND GENOTYPE ON PSA AT 2 WEEKS. CONCLUSIONS: IN THIS STUDY, BDNF METHYLATION IN COMBINATION WITH THE MET/MET BDNF POLYMORPHISM (VAL66MET POLYMORPHISM) WAS ASSOCIATED WITH PSA. THESE FINDINGS MAY HELP IDENTIFY PATIENTS AT HIGHER RISK FOR PSA.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
8   846  39 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	
                                                                                                                                                                                                                                                                                                                         
9   362  35 AMBIENT AIR POLLUTION IMPAIRS REGULATORY T-CELL FUNCTION IN ASTHMA. BACKGROUND: ASTHMA IS THE MOST FREQUENT CHRONIC DISEASE IN CHILDREN, AND CHILDREN ARE AT HIGH RISK FOR ADVERSE HEALTH CONSEQUENCES ASSOCIATED WITH AMBIENT AIR POLLUTION (AAP) EXPOSURE. REGULATORY T (TREG) CELLS ARE SUPPRESSORS OF IMMUNE RESPONSES INVOLVED IN ASTHMA PATHOGENESIS. TREG-CELL IMPAIRMENT IS ASSOCIATED WITH INCREASED DNA METHYLATION OF FORKHEAD BOX TRANSCRIPTION FACTOR 3 (FOXP3), A KEY TRANSCRIPTION FACTOR IN TREG-CELL ACTIVITY. BECAUSE AAP EXPOSURE CAN INDUCE EPIGENETIC CHANGES, WE HYPOTHESIZED THAT TREG-CELL FUNCTION WOULD BE IMPAIRED BY AAP, ALLOWING AMPLIFICATION OF AN INFLAMMATORY RESPONSE. OBJECTIVES: TO ASSESS WHETHER EXPOSURE TO AAP LED TO HYPERMETHYLATION OF THE FOXP3 GENE, CAUSING IMPAIRED TREG-CELL SUPPRESSION AND WORSENED ASTHMA SYMPTOM SCORES. METHODS: CHILDREN WITH AND WITHOUT ASTHMA FROM FRESNO, CALIF (HIGH POLLUTION, FRESNO ASTHMA GROUP [FA], N = 71, AND FRESNO NON ASTHMATIC GROUP, N = 30, RESPECTIVELY), AND FROM STANFORD, CALIF (LOW POLLUTION, STANFORD ASTHMA GROUP, N = 40, AND STANFORD NON ASTHMATIC GROUP, N = 40), WERE ENROLLED IN A CROSS-SECTIONAL STUDY. PERIPHERAL BLOOD TREG CELLS WERE USED IN FUNCTIONAL AND EPIGENETIC STUDIES. ASTHMA OUTCOMES WERE ASSESSED BY GLOBAL INITIATIVE IN ASTHMA SCORE. RESULTS: FRESNO ASTHMA GROUP TREG-CELL SUPPRESSION WAS IMPAIRED AND FA TREG-CELL CHEMOTAXIS WERE REDUCED COMPARED WITH OTHER GROUPS (P </= .05). TREG-CELL DYSFUNCTION WAS ASSOCIATED WITH MORE PRONOUNCED DECREASES IN ASTHMA GLOBAL INITIATIVE IN ASTHMA SCORE IN FA VERSUS THE STANFORD ASTHMA GROUP. FOXP3 WAS DECREASED IN FA COMPARED WITH THE FRESNO NON ASTHMATIC GROUP (P </= .05). FA ALSO CONTAINED SIGNIFICANTLY HIGHER LEVELS OF METHYLATION AT THE FOXP3 LOCUS (P </= .05). CONCLUSION: INCREASED EXPOSURE TO AAP IS ASSOCIATED WITH HYPERMETHYLATION OF THE FOXP3 LOCUS, IMPAIRING TREG-CELL FUNCTION AND INCREASING ASTHMA MORBIDITY. AAP COULD PLAY A ROLE IN MEDIATING EPIGENETIC CHANGES IN TREG CELLS, WHICH MAY WORSEN ASTHMA BY AN IMMUNE MECHANISM.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
10  6813  28 [EPILEPSY-ASSOCIATED TUMORS OF THE CENTRAL NERVOUS SYSTEM: EPILEPSY SURGERY AND ONCOLOGICAL ASPECTS]. BACKGROUND: AMONG THE TUMORS ASSOCIATED WITH CHRONIC EPILEPSY, DYSEMBRYOPLASTIC NEUROEPITHELIAL TUMOR AND GANGLIOGLIOMA ARE THE MOST COMMON BESIDES ANGIOCENTRIC GLIOMA, PLEOMORPHIC XANTHOASTROCYTOMA AND PILOCYTIC ASTROCYTOMA. THESE TUMORS ARE USUALLY CONSIDERED AS BEING BENIGN. OBJECTIVE: TO DETERMINE THE BEST CONSERVATIVE AND SURGICAL TREATMENT OF TUMORS ASSOCIATED WITH EPILEPSY. MATERIAL AND METHODS: THIS ARTICLE PRESENTS CASE REPORTS OF MALIGNANT TRANSFORMATION OF A DYSEMBRYOPLASTIC NEUROEPITHELIAL TUMOR AND OF A TUMOR INITIALLY DIAGNOSED AS A GANGLIOGLIOMA BASED ON MAGNETIC RESONANCE IMAGING (MRI) CRITERIA. DESCRIPTION OF REFERENCES IN THE LITERATURE ON EPILEPSY SURGERY AND THE NEURO-ONCOLOGY OF EPILEPSY-ASSOCIATED TUMORS. RESULTS: IN THE CASE OF THE INITIALLY HISTOPATHOLOGICALLY DIAGNOSED DYSEMBRYOPLASTIC NEUROEPITHELIAL TUMOR, A MALIGNANT TRANSFORMATION OCCURRED 5 YEARS AFTER INCOMPLETE RESECTION. THE DIFFERENTIATION FROM A GLIOBLASTOMA WAS POSSIBLE THROUGH THE ANALYSIS OF THE METHYLATION PROFILE. IN ANOTHER CASE A TUMOR ASSUMED TO BE A GANGLIOGLIOMA SHOWED AN INCREASE IN SIZE AFTER 6 YEARS. INITIAL HISTOPATHOLOGICAL RESULTS REVEALED A GLIOBLASTOMA. THE ANALYSIS OF THE METHYLATION PROFILE SUGGESTED THE DIAGNOSIS OF AN ANAPLASTIC PLEOMORPHIC XANTHOASTROCYTOMA AND AS A DIFFERENTIAL DIAGNOSIS AN ANAPLASTIC GANGLIOGLIOMA. TUMOR PROGRESS CORRELATED WITH THE WORSENING OF SEIZURES. CONCLUSION: RECENT STUDIES HAVE SHOWN THAT IN THE TREATMENT OF PREDOMINANTLY BENIGN EPILEPSY-ASSOCIATED TUMORS NEURO-ONCOLOGICAL ASPECTS SHOULD ALSO BE TAKEN INTO ACCOUNT IN ADDITION TO THE EPILEPTOLOGICAL CONSIDERATIONS. IN THE CASE OF MALIGNANT TRANSFORMATION EPIGENETIC SCREENING (METHYLATION PROFILES) CAN HELP TO CLASSIFY THE TUMOR ENTITY MORE PRECISELY.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
11   133  34 AAV-MEDIATED EXPRESSION OF SECRETED AND TRANSMEMBRANE ALPHAKLOTHO ISOFORMS RESCUES RELEVANT AGING HALLMARKS IN SENESCENT SAMP8 MICE. SENESCENCE REPRESENTS A STAGE IN LIFE ASSOCIATED WITH ELEVATED INCIDENCE OF MORBIDITY AND INCREASED RISK OF MORTALITY DUE TO THE ACCUMULATION OF MOLECULAR ALTERATIONS AND TISSUE DYSFUNCTION, PROMOTING A DECREASE IN THE ORGANISM'S PROTECTIVE SYSTEMS. THUS, AGING PRESENTS MOLECULAR AND BIOLOGICAL HALLMARKS, WHICH INCLUDE CHRONIC INFLAMMATION, EPIGENETIC ALTERATIONS, NEURONAL DYSFUNCTION, AND WORSENING OF PHYSICAL STATUS. IN THIS CONTEXT, WE EXPLORED THE AAV9-MEDIATED EXPRESSION OF THE TWO MAIN ISOFORMS OF THE AGING-PROTECTIVE FACTOR KLOTHO (KL) AS A STRATEGY TO PREVENT THESE GENERAL AGE-RELATED FEATURES USING THE SENESCENCE-ACCELERATED MOUSE PRONE 8 (SAMP8) MODEL. BOTH SECRETED AND TRANSMEMBRANE KL ISOFORMS IMPROVED COGNITIVE PERFORMANCE, PHYSICAL STATE PARAMETERS, AND DIFFERENT MOLECULAR VARIABLES ASSOCIATED WITH AGING. EPIGENETIC LANDSCAPE WAS RECOVERED FOR THE ANALYZED GLOBAL MARKERS DNA METHYLATION (5-MC), HYDROXYMETHYLATION (5-HMC), AND RESTORATION OCCURRED IN THE ACETYLATION LEVELS OF H3 AND H4. GENE EXPRESSION OF PRO- AND ANTI-INFLAMMATORY MEDIATORS IN CENTRAL NERVOUS SYSTEM SUCH AS TNF-ALPHA AND IL-10, RESPECTIVELY, HAD IMPROVED LEVELS, WHICH WERE COMPARABLE TO THE SENESCENCE-ACCELERATED-MOUSE RESISTANT 1 (SAMR1) HEALTHY CONTROL. ADDITIONALLY, THIS IMPROVEMENT IN NEUROINFLAMMATION WAS SUPPORTED BY CHANGES IN THE HISTOLOGICAL MARKERS IBA1, GFAP, AND SA BETA-GAL. FURTHERMORE, BONE TISSUE STRUCTURAL VARIABLES, ESPECIALLY ALTERED DURING SENESCENCE, RECOVERED IN SAMP8 MICE TO SAMR1 CONTROL VALUES AFTER TREATMENT WITH BOTH KL ISOFORMS. THIS WORK PRESENTS EVIDENCE OF THE BENEFICIAL PLEIOTROPIC ROLE OF KLOTHO AS AN ANTI-AGING THERAPY AS WELL AS NEW SPECIFIC FUNCTIONS OF THE KL ISOFORMS FOR THE EPIGENETIC REGULATION AND AGED BONE STRUCTURE ALTERATION IN AN AGING MOUSE MODEL.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
12  2900  25 GENDER BIAS IN THERAPEUTIC EFFORT: FROM RESEARCH TO HEALTH CARE. THERE ARE RELEVANT DIMENSIONS FROM A GENDER PERSPECTIVE RELATED TO THERAPEUTIC EFFORT. TO ILLUSTRATE AND DISCUSS POSSIBLE GENDER BIAS RELATED TO MEDICINES, THROUGH THE CONSUMPTION ANALYSIS IN WOMEN, THE PRESCRIPTION OF BIOLOGICAL DRUGS ACCORDING TO SEX, THE POTENTIAL GENDER INEQUALITY IN ADVERSE DRUG REACTIONS, AND RESEARCH WITH CLINICAL TRIALS, AS WELL AS THE DECISIONS OF INTERNATIONAL INSTITUTIONS IN THE MARKETING OF MEDICINAL PRODUCTS. THERE IS GREATER TENDENCY TO PRESCRIBE PAIN RELIEVERS, REGARDLESS OF PAIN, AND DRUGS FOR LOW INTENSITY DEPRESSIVE SYMPTOMS IN WOMEN THAN IN MEN. THE OPPOSITE OCCURS IN THE PRESCRIPTION OF STATINS AND ADEQUATE DOSES, AND WITH THE GREATER PROBABILITY OF PRESCRIBING ANTI-TUMOR NECROSIS FACTOR IN MEN THAN IN WOMEN WITH ANKYLOSING SPONDYLITIS, DESPITE A SIMILAR DISEASE BURDEN. ADVERSE DRUG REACTIONS ARE OBSERVED MORE FREQUENTLY IN WOMEN THAN IN MEN, WHERE DETERMINANTS SUCH AS BODY WEIGHT ARE HAVING LITTLE INFLUENCE ON THE DOSAGE. IT IS CURRENTLY SCARCELY CONSIDERED IN THE PRESCRIPTION THAT WOMEN HAVE DIFFERENCES IN THE ACTIVITY OF CYTOCHROME CYPP450 ENZYMES, WHICH CAN AFFECT THE LIVER'S METABOLISM RATE. THERE ARE EVEN IMMUNOLOGICAL, GENETIC AND EPIGENETIC EFFECTS (DUE TO HEREDITY AND UNEVEN GENE DOSING LOCATED IN THE X AND Y CHROMOSOMES) THAT CAN INFLUENCE THESE DIFFERENCES BY SEX. FINALLY, THROUGH CASES OF HORMONAL THERAPY CLINICAL TRIALS, A DRUG FOR WOMEN'S INHIBITED SEXUAL DESIRE AND A CONTRACEPTIVE FOR MEN, GENDER BIAS AND STEREOTYPES ARE SHOWN TO INFLUENCE A POTENTIAL GENERATION OF INEQUALITIES, ESPECIALLY IN ADVERSE DRUG REACTIONS TO THE DETRIMENT OF WOMEN. IN CONCLUSION, HEALTH PROFESSIONALS FREQUENTLY ATTRIBUTE PHYSICAL SYMPTOMS TO WOMEN'S EMOTIONALITY, INFLUENCING THEIR GREATER PRESCRIPTION OF SYMPTOMATIC DRUGS. WHETHER THE SAME REASON INFLUENCES THE LOWER PRESCRIPTION OF THERAPEUTIC DRUGS IN WOMEN THAN IN MEN SHOULD BE ANALYZED. THERE ARE BIOLOGICAL DETERMINANTS TO CONSIDER DUE TO THEIR INFLUENCE ON A GREATER PHARMACOLOGICAL TOXICITY IN WOMEN. CLINICAL TRIALS SHOULD IMPROVE ACCORDING TO THE GENDER RECOMMENDATIONS BY THE FOOD AND DRUGS ADMINISTRATION.	2020	
                                                                                                                                                                                                                                                                                                                                       
13  3850  42 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
14  1058  30 CLINICAL MEASURES OF ALLOSTATIC LOAD IN CHILDREN AND ADOLESCENTS WITH FOOD ALLERGY, DEPRESSION, OR ANXIETY. PURPOSE: SUSTAINED HIGH STRESS EXPOSURE RESULTS IN CHRONIC ACTIVATION OF THE STRESS RESPONSE SYSTEM, DYSREGULATED STRESS RESPONSES, HIGH ALLOSTATIC LOAD, AND POOR LATER-LIFE HEALTH. CHILDREN AND ADOLESCENTS WITH CHRONIC HEALTH CONDITIONS FACE STRESSORS RELATED TO THEIR CONDITION IN ADDITION TO THOSE TYPICAL OF CHILDHOOD AND ADOLESCENCE, PLACING THEM AT RISK OF HIGH ALLOSTATIC LOAD. THE PURPOSE OF THIS SECONDARY ANALYSIS WAS TO EXAMINE WHETHER YOUTH WITH CHRONIC HEALTH CONDITIONS DIFFER FROM CONTROLS ON CLINICAL MEASURES OF ALLOSTATIC LOAD. DESIGN AND METHODS: A SECONDARY ANALYSIS OF TWO DATASETS, THE ELECTRONIC HEALTH RECORD OF A TERTIARY CHILDREN'S HOSPITAL AND DATA FROM THE SURVEY OF THE HEALTH OF WISCONSIN, COMPARED YOUTH WITH CHRONIC HEALTH CONDITIONS TO CONTROLS ON CLINICAL MEASURES OF ALLOSTATIC LOAD. ADDITIONAL ANALYSES EXPLORED WHETHER PARENTAL STRESS AND MENTAL HEALTH INFLUENCED THESE RELATIONSHIPS. RESULTS: ANALYSES IDENTIFIED DIFFERENCES IN BMI, BLOOD PRESSURE, AND WAIST CIRCUMFERENCE BETWEEN YOUTH WITH FOOD ALLERGY, ANXIETY, OR DEPRESSION, AND CONTROLS. THESE RELATIONSHIPS DIFFERED FOR MALES AND FEMALES AND FOR THOSE WITH COMORBID MENTAL AND PHYSICAL CONDITIONS, AND WERE INFLUENCED BY PARENT STRESS AND MENTAL HEALTH. CONCLUSIONS: RESULTS SUPPORT FUTURE STUDIES EXPLORING WHETHER HIGH STRESS IN YOUTH WITH CHRONIC HEALTH CONDITIONS LEADS TO INCREASED ALLOSTATIC LOAD. INCORPORATING BIOMARKERS AS WELL AS GENETIC AND EPIGENETIC FACTORS WILL PROVIDE CRITICAL INSIGHTS. PRACTICE IMPLICATIONS: YOUTH WITH MENTAL AND PHYSICAL CHCS MAY BE AT INCREASED RISK OF HIGH ALLOSTATIC LOAD, REFLECTED IN CLINICAL MEASURES OF METABOLISM, AND SHOULD HAVE REGULAR ASSESSMENTS OF THEIR METABOLIC HEALTH.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
15   852  34 CHOLANGIOCARCINOMA IN PATIENTS WITH PRIMARY SCLEROSING CHOLANGITIS (PSC): A COMPREHENSIVE REVIEW. CHOLANGIOCARCINOMA (CCA) IS THE MOST COMMON MALIGNANCY IN PATIENTS WITH PRIMARY SCLEROSING CHOLANGITIS (PSC) AND CARRIES A HIGH RATE OF MORTALITY. ALTHOUGH THE PATHOGENESIS OF CCA IN PSC IS LARGELY UNKNOWN, INFLAMMATION-DRIVEN CARCINOGENESIS CONCOMITANT WITH VARIOUS GENETIC AND EPIGENETIC ABNORMALITIES ARE UNDERLYING FACTORS. THE MAJORITY OF CCA CASES DEVELOP FROM A DOMINANT STRICTURE (DS), WHICH IS DEFINED AS A STRICTURE WITH A DIAMETER < 1.5 MM IN THE COMMON BILE DUCT OR < 1.0 MM IN THE HEPATIC DUCT. IN PSC PATIENTS PRESENTING WITH AN ABRUPT AGGRAVATION OF JAUNDICE, PAIN, FATIGUE, PRURITUS, WEIGHT LOSS, OR WORSENING LIVER BIOCHEMISTRIES, CCA SHOULD BE SUSPECTED AND EVALUATED UTILIZING A VARIETY OF DIAGNOSTIC MODALITIES. HOWEVER, EARLY RECOGNITION OF CCA IN PSC REMAINS A MAJOR CHALLENGE. IMPORTANTLY, 30-50% OF CCA IN PSC PATIENTS ARE OBSERVED WITHIN THE FIRST YEAR FOLLOWING THE DIAGNOSIS OF PSC FOLLOWED BY AN ANNUAL INCIDENCE RANGING FROM 0.5 TO 1.5 PER 100 PERSONS, WHICH IS NEARLY 10 TO 1000 TIMES HIGHER THAN THAT IN THE GENERAL POPULATION. CUMULATIVE 5-YEAR, 10-YEAR, AND LIFETIME INCIDENCES ARE 7%, 8-11%, AND 9-20%, RESPECTIVELY. WHEN PSC-ASSOCIATED CCA IS DIAGNOSED, MOST TUMORS ARE UNRESECTABLE, AND NO EFFECTIVE MEDICATIONS ARE AVAILABLE. GIVEN THE POOR THERAPEUTIC OUTCOME, THE SURVEILLANCE AND MANAGEMENT OF PSC PATIENTS WHO ARE AT AN INCREASED RISK OF DEVELOPING CCA ARE OF IMPORTANCE. SUCH PATIENTS INCLUDE OLDER MALES WITH LARGE-DUCT PSC AND POSSIBLY CONCURRENT ULCERATIVE COLITIS. THUS, MORE ATTENTION SHOULD BE PAID TO PATIENTS WITH THESE CLINICAL FEATURES, IN PARTICULAR WITHIN THE FIRST YEAR AFTER PSC DIAGNOSIS. IN CONTRAST, CCA IS LESS FREQUENTLY OBSERVED IN PEDIATRIC OR FEMALE PSC PATIENTS OR IN THOSE WITH SMALL-DUCT PSC OR CONCURRENT CROHN'S DISEASE. RECENTLY, NEW BIOMARKERS SUCH AS ANTIBODIES TO GLYCOPROTEIN 2 HAVE BEEN FOUND TO BE ASSOCIATED WITH AN INCREASED RISK OF DEVELOPING CCA IN PSC. HEREIN, WE REVIEW THE LITERATURE ON THE PATHOGENESIS, INCIDENCE, CLINICAL FEATURES, AND RISK FACTORS, WITH A FOCUS ON VARIOUS DIAGNOSTIC MODALITIES OF PSC-ASSOCIATED CCA.	2020	
                                                                                                                                                                                                                                                                                                                            
16  5008  31 PERIPUBERTAL STRESS WITH SOCIAL SUPPORT PROMOTES RESILIENCE IN THE FACE OF AGING. THE PERIPUBERTAL PERIOD OF DEVELOPMENT IS A SENSITIVE WINDOW, DURING WHICH ADVERSE EXPERIENCES CAN INCREASE THE RISK FOR PRESENTATION OF COGNITIVE AND AFFECTIVE DYSFUNCTION THROUGHOUT THE LIFESPAN, ESPECIALLY IN WOMEN. HOWEVER, SUCH EXPERIENCES IN THE CONTEXT OF A SUPPORTIVE SOCIAL ENVIRONMENT CAN ACTUALLY AMELIORATE THIS RISK, SUGGESTING THAT RESILIENCE CAN BE PROGRAMMED IN EARLY LIFE. AFFECTIVE DISORDERS AND COGNITIVE DEFICITS COMMONLY EMERGE DURING AGING, WITH MANY WOMEN REPORTING INCREASED DIFFICULTY WITH PREFRONTAL CORTEX (PFC)-DEPENDENT EXECUTIVE FUNCTIONS. WE HAVE DEVELOPED A MOUSE MODEL TO EXAMINE THE INTERACTION BETWEEN PERIPUBERTAL EXPERIENCE AND AGE-RELATED CHANGES IN COGNITION AND STRESS REGULATION. FEMALE MICE WERE EXPOSED TO PERIPUBERTAL CHRONIC STRESS, DURING WHICH THEY WERE EITHER INDIVIDUALLY HOUSED OR HOUSED WITH SOCIAL INTERACTION. ONE YEAR AFTER THIS STRESS EXPERIENCE, MICE WERE EXAMINED IN TASKS TO ACCESS THEIR COGNITIVE ABILITY AND FLEXIBILITY IN STRESS REACTIVE MEASURES. IN A TEST OF SPATIAL MEMORY ACQUISITION AND REVERSAL LEARNING WHERE AGED FEMALES NORMALLY DISPLAY A DECREASED PERFORMANCE, THE FEMALES THAT HAD EXPERIENCED STRESS WITH SOCIAL INTERACTION A YEAR EARLIER SHOWED IMPROVED PERFORMANCE IN REVERSAL LEARNING, A MEASURE OF COGNITIVE FLEXIBILITY. BECAUSE PERIPUBERTY IS A TIME OF MAJOR PFC MATURATION, WE PERFORMED TRANSCRIPTOMIC AND BIOCHEMICAL ANALYSIS OF THE AGED PFC, IN WHICH LONG-TERM CHANGES IN MICRORNA EXPRESSION AND IN MYELIN PROTEINS WERE FOUND. THESE DATA SUGGEST THAT STRESS IN THE CONTEXT OF SOCIAL SUPPORT EXPERIENCED OVER THE PUBERTAL WINDOW CAN PROMOTE EPIGENETIC REPROGRAMMING IN THE BRAIN TO INCREASE THE RESILIENCE TO AGE-RELATED COGNITIVE DECLINE IN FEMALES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
17  6406  26 THE SEARCH FOR RELIABLE BIOMARKERS OF DISEASE IN MULTIPLE CHEMICAL SENSITIVITY AND OTHER ENVIRONMENTAL INTOLERANCES. WHILST FACING A WORLDWIDE FAST INCREASE OF FOOD AND ENVIRONMENTAL ALLERGIES, THE MEDICAL COMMUNITY IS ALSO CONFRONTED WITH ANOTHER INHOMOGENEOUS GROUP OF ENVIRONMENT-ASSOCIATED DISABLING CONDITIONS, INCLUDING MULTIPLE CHEMICAL SENSITIVITY (MCS), FIBROMYALGIA, CHRONIC FATIGUE SYNDROME, ELECTRIC HYPERSENSITIVITY, AMALGAM DISEASE AND OTHERS. THESE SHARE THE FEATURES OF POLY-SYMPTOMATIC MULTI-ORGAN CUTANEOUS AND SYSTEMIC MANIFESTATIONS, WITH POSTULATED INHERITED/ACQUIRED IMPAIRED METABOLISM OF CHEMICAL/PHYSICAL/NUTRITIONAL XENOBIOTICS, TRIGGERING ADVERSE REACTIONS AT EXPOSURE LEVELS FAR BELOW TOXICOLOGICALLY-RELEVANT VALUES, OFTEN IN THE ABSENCE OF CLEAR-CUT ALLERGOLOGIC AND/OR IMMUNOLOGIC INVOLVEMENT. DUE TO THE LACK OF PROVEN PATHOGENIC MECHANISMS GENERATING MEASURABLE DISEASE BIOMARKERS, THESE ENVIRONMENTAL HYPERSENSITIVITIES ARE GENERALLY IGNORED BY SANITARY AND SOCIAL SYSTEMS, AS PSYCHOGENIC OR "MEDICALLY UNEXPLAINED SYMPTOMS". THE UNCONTROLLED APPLICATION OF DIAGNOSTIC AND TREATMENT PROTOCOLS NOT CORRESPONDING TO ACCEPTABLE LEVELS OF VALIDATION, SAFETY, AND CLINICAL EFFICACY, TO A STEADILY INCREASING NUMBER OF PATIENTS DEMANDING ASSISTANCE, OCCURS IN MANY COUNTRIES IN THE ABSENCE OF EVIDENCE-BASED GUIDELINES. HERE WE REVISE AVAILABLE INFORMATION SUPPORTING THE ORGANIC NATURE OF THESE CLINICAL CONDITIONS. FOLLOWING INTENSE RESEARCH ON GENE POLYMORPHISMS OF PHASE I/II DETOXIFICATION ENZYME GENES, SO FAR STATISTICALLY INCONCLUSIVE, EPIGENETIC AND METABOLIC FACTORS ARE UNDER INVESTIGATION, IN PARTICULAR FREE RADICAL/ANTIOXIDANT HOMEOSTASIS DISTURBANCES. THE FINDING OF RELEVANT ALTERATIONS OF CATALASE, GLUTATHIONE-TRANSFERASE AND PEROXIDASE DETOXIFYING ACTIVITIES SIGNIFICANTLY CORRELATING WITH CLINICAL MANIFESTATIONS OF MCS, HAS RECENTLY REGISTERED SOME PROGRESS TOWARDS THE IDENTIFICATION OF RELIABLE BIOMARKERS OF DISEASE ONSET, PROGRESSION, AND TREATMENT OUTCOMES.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
18  5302  39 PROTEIN-C REACTIVE AS BIOMARKER PREDICTOR OF SCHIZOPHRENIA PHASES OF ILLNESS? A SYSTEMATIC REVIEW. BACKGROUND: SCHIZOPHRENIA IS A COMPLEX ILLNESS IN WHICH GENETIC, ENVIRONMENTAL, AND EPIGENETIC COMPONENTS HAVE BEEN IMPLICATED. HOWEVER, RECENTLY, PSYCHIATRIC DISORDERS APPEAR TO BE RELATED TO A CHRONIC INFLAMMATORY STATE, AT THE LEVEL OF SPECIFIC CEREBRAL AREAS WHICH HAVE BEEN FOUND AS WELL IMPAIRED AND RESPONSIBLE FOR SCHIZOPHRENIA SYMPTOMATOLOGY. HENCE, A ROLE OF INFLAMMATORY MEDIATORS AND CYTOKINES HAS BEEN AS WELL DEFINED. ACCORDINGLY, THE ROLE OF AN ACUTE INFLAMMATORY PHASE PROTEIN, THE C-REACTIVE PROTEIN (CRP) HAS BEEN RECENTLY INVESTIGATED. OBJECTIVE: THE OBJECTIVE OF THE PRESENT STUDY IS TO EVALUATE HOW PCR MAY REPRESENT A BIOMARKER IN SCHIZOPHRENIA, I.E. CORRELATED WITH ILLNESS PHASES AND/OR CLINICAL MANIFESTATION AND/OR PSYCHOPATHOLOGICAL SEVERITY. METHODS: A SYSTEMATIC REVIEW WAS HERE CARRIED OUT BY SEARCHING THE FOLLOWING KEYWORDS ((C-REACTIVE PROTEIN AND ((SCHIZOPHRENIA) OR (PSYCHOTIC DISORDER))) FOR THE TOPICS 'PCR' AND 'SCHIZOPHRENIA', BY USING MESH TERMS. RESULTS: AN IMMUNE DYSFUNCTION AND INFLAMMATION HAVE BEEN DESCRIBED AMONGST SCHIZOPHRENIC PATIENTS. FINDINGS REPORTED ELEVATED CRP LEVELS IN SCHIZOPHRENIA, MAINLY CORRELATED WITH THE SEVERITY OF ILLNESS AND DURING THE RECRUDESCENT PHASE. CRP LEVELS ARE HIGHER WHEN CATATONIC FEATURES, NEGATIVE SYMPTOMATOLOGY AND AGGRESSIVENESS ARE ASSOCIATED. CRP LEVELS APPEARED NOT TO BE RELATED TO SUICIDAL BEHAVIOUR AND IDEATION. CONCLUSION: CRP AND ITS BLOOD LEVELS HAVE BEEN REPORTED HIGHER AMONGST SCHIZOPHRENIC PATIENTS, BY SUGGESTING A ROLE OF INFLAMMATION IN THE PATHOGENESIS OF SCHIZOPHRENIA. FURTHER STUDIES ARE NEEDED TO BETTER UNDERSTAND IF CRP MAY BE CONSIDERED A BIOMARKER IN SCHIZOPHRENIA.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
19  2734  38 EXPLORING THE RELATIONSHIP BETWEEN DNA METHYLATION AGE MEASURES AND PSYCHONEUROLOGICAL SYMPTOMS IN WOMEN WITH EARLY-STAGE BREAST CANCER. PURPOSE: THE EPIGENETIC CLOCK HAS BEEN ACKNOWLEDGED AS AN INDICATOR FOR MOLECULAR AGING, BUT FEW STUDIES HAVE EXAMINED POSSIBLE ASSOCIATIONS OF DNA METHYLATION (DNAM) AGE OR AGE ACCELERATION (AA) WITH SYMPTOM BURDEN IN INDIVIDUALS WHO ARE TREATED FOR CANCER. THIS STUDY EXPLORED THE ASSOCIATION OF DNAM AGE OR AA WITH PSYCHONEUROLOGICAL (PN) SYMPTOMS, INCLUDING COGNITIVE IMPAIRMENT, FATIGUE, SLEEP DISTURBANCES, PAIN, AND DEPRESSIVE SYMPTOMS, IN BREAST CANCER SURVIVORS OVER A 2-YEAR PERIOD. METHODS: WE MEASURED PN SYMPTOMS USING RELIABLE INSTRUMENTS AND DNAM LEVELS BY INFINIUM HUMANMETHYLATION450K BEADCHIP (N = 72). DNAM AGE WAS CALCULATED BY THE HORVATH, GRIM, AND HANNUM-BASED INTRINSIC AND EXTRINSIC AGE ESTIMATIONS. AA WAS DEFINED BY THE RESIDUAL REGRESSING ESTIMATED EPIGENETIC AGE ON CHRONOLOGICAL AGE. MIXED REGRESSION MODELS WERE FITTED FOR AA AND CHANGES IN AA TO STUDY THE ASSOCIATION OVER TIME. SEPARATE LINEAR REGRESSION MODELS AND A MIXED-EFFECTS MODEL WERE FITTED FOR AA AT EACH TIME POINT. RESULTS: HORVATH-AA, GRIM-AA, AND EXTRINSIC EPIGENETIC AA WERE SIGNIFICANTLY CHANGED OVER TIME, WHILE INTRINSIC EPIGENETIC AA DID NOT EXHIBIT ANY TEMPORAL CHANGES. INCREASED AA WAS ASSOCIATED WITH GREATER ANXIETY AND FATIGUE, AS WELL AS WORSE COGNITIVE MEMORY, ADJUSTING FOR RACE, BMI, INCOME, CHEMOTHERAPY, RADIATION THERAPY, AND CHRONOLOGICAL AGE. INCREASED DNAM AGE WAS ASSOCIATED WITH GREATER ANXIETY OVER 2 YEARS. CONCLUSION: OUR FINDINGS SUGGEST DNAM AGE AND AA MAY BE ASSOCIATED WITH PN SYMPTOMS OVER THE COURSE OF CANCER TREATMENT AND SURVIVORSHIP. SOME PN SYMPTOMS MAY BE AMENABLE TO PREVENTIVE INTERVENTIONS TARGETED TO EPIGENETIC CLOCKS THAT INFLUENCE AGING-ASSOCIATED PROCESSES.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
20  5129  35 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
