1  5612 267 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.

2  3553  42 IMMUNOTOLERANCE OF DAIRY HEIFERS IN RESPONSE TO REPEATED EXPOSURE TO BACTERIAL LIPOPOLYSACCHARIDE ENDOTOXIN. DAIRY CATTLE FACE A VARIETY OF STRESSFUL EVENTS ON A DAILY BASIS. 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
3  5478  48 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
4   765  56 CC-486 MAINTENANCE AFTER STEM CELL TRANSPLANTATION IN PATIENTS WITH ACUTE MYELOID LEUKEMIA OR MYELODYSPLASTIC SYNDROMES. RELAPSE IS THE MAIN CAUSE OF TREATMENT FAILURE AFTER ALLOGENEIC STEM CELL TRANSPLANT (ALLOSCT) IN ACUTE MYELOID LEUKEMIA (AML) AND MYELODYSPLASTIC SYNDROMES (MDS). INJECTABLE AZACITIDINE CAN IMPROVE POST-TRANSPLANT OUTCOMES BUT PRESENTS CHALLENGES WITH EXPOSURE AND COMPLIANCE. ORAL CC-486 ALLOWS EXTENDED DOSING TO PROLONG AZACITIDINE ACTIVITY. WE INVESTIGATED USE OF CC-486 MAINTENANCE THERAPY AFTER ALLOSCT. ADULTS WITH MDS OR AML IN MORPHOLOGIC COMPLETE REMISSION AT CC-486 INITIATION (42 TO 84 DAYS AFTER ALLOSCT) WERE INCLUDED. PATIENTS RECEIVED 1 OF 4 CC-486 DOSING SCHEDULES PER 28-DAY CYCLE FOR UP TO 12 CYCLES. ENDPOINTS INCLUDED SAFETY, PHARMACOKINETICS, GRAFT-VERSUS-HOST DISEASE (GVHD) INCIDENCE, RELAPSE/PROGRESSION RATE, AND SURVIVAL. OF 30 PATIENTS, 7 RECEIVED CC-486 ONCE DAILY FOR 7 DAYS PER CYCLE (200 MG, N = 3; 300 MG, N = 4) AND 23 FOR 14 DAYS PER CYCLE (150 MG, N = 4; 200 MG, N = 19 [EXPANSION COHORT]). GRADES 3 TO 4 ADVERSE EVENTS WERE INFREQUENT AND OCCURRED WITH SIMILAR FREQUENCY ACROSS REGIMENS. STANDARD CONCOMITANT MEDICATIONS DID NOT ALTER CC-486 PHARMACOKINETIC PARAMETERS. THREE PATIENTS (10%) EXPERIENCED GRADE III ACUTE GVHD AND 9 EXPERIENCED CHRONIC GVHD. OF 28 EVALUABLE PATIENTS, 6 (21%) RELAPSED OR HAD PROGRESSIVE DISEASE: 3 OF 7 PATIENTS (43%) WHO HAD RECEIVED 7-DAY DOSING AND 3 OF 23 (13%) WHO HAD RECEIVED 14-DAY DOSING. TRANSPLANT-RELATED MORTALITY WAS 3%. AT 19 MONTHS OF FOLLOW-UP, MEDIAN OVERALL SURVIVAL WAS NOT REACHED. ESTIMATED 1-YEAR SURVIVAL RATES WERE 86% AND 81% IN THE 7-DAY AND 14-DAY DOSING COHORTS, RESPECTIVELY. CC-486 MAINTENANCE WAS GENERALLY WELL TOLERATED, WITH LOW RATES OF RELAPSE, DISEASE PROGRESSION, AND GVHD. CC-486 MAINTENANCE MAY PERMIT EPIGENETIC MANIPULATION OF THE ALLOREACTIVE RESPONSE POSTALLOGRAFT. FINDINGS REQUIRE CONFIRMATION IN RANDOMIZED TRIALS.

5  2822  74 FIRST-IN-HUMAN STUDY OF INHALED AZACITIDINE IN PATIENTS WITH ADVANCED NON-SMALL CELL LUNG CANCER. BACKGROUND: AEROSOLIZED AZACITIDINE HAS BEEN SHOWN TO INHIBIT ORTHOTOPIC LUNG CANCER GROWTH AND INDUCE RE-EXPRESSION OF METHYLATED TUMOR SUPPRESSOR GENES IN MURINE MODELS. WE HYPOTHESIZED THAT INHALED AZACITIDINE IS SAFE AND EFFECTIVE IN REVERSING EPIGENETIC CHANGES IN THE BRONCHIAL EPITHELIUM SECONDARY TO CHRONIC SMOKING. PATIENTS AND METHODS: WE REPORT THE FIRST IN HUMAN STUDY OF INHALED AZACITIDINE. AZACITIDINE IN AQUEOUS SOLUTION WAS USED TO GENERATE AN AEROSOL SUSPENSION OF 0.25-5 MUM PARTICLE SIZE. MAIN INCLUSION CRITERIA: STAGE IV OR RECURRENT NSCLC WITH PREDOMINANTLY LUNG INVOLVEMENT, >/=1 PRIOR SYSTEMIC THERAPY, ECOG PS 0-1, AND ADEQUATE PULMONARY FUNCTION. PATIENTS RECEIVED INHALED AZACITIDINE DAILY ON DAYS 1-5 AND 15-19 OF 28-DAY CYCLES, AT 3 ESCALATING DOSES (15, 30 AND 45 MG/M(2) DAILY). THE PRIMARY OBJECTIVE WAS TO DETERMINE THE FEASIBILITY AND TOLERABILITY OF THIS NEW THERAPEUTIC MODALITY. THE KEY SECONDARY OBJECTIVES INCLUDED PHARMACOKINETICS, METHYLATION PROFILES AND EFFICACY. RESULTS: FROM 3/2015 TO 2/2018, EIGHT PATIENTS RECEIVED A MEDIAN NUMBER OF 2 (IQR = 1) CYCLES OF INHALED AZACITIDINE. NO CLINICALLY SIGNIFICANT ADVERSE EVENTS WERE OBSERVED, EXCEPT ONE PATIENT TREATED AT THE HIGHEST DOSE DEVELOPED AN ASYMPTOMATIC GRADE 2 DECREASED DLCO WHICH RESOLVED SPONTANEOUSLY. ONE PATIENT RECEIVING 12 CYCLES OF THERAPY HAD AN OBJECTIVE AND DURABLE PARTIAL RESPONSE, AND TWO PATIENTS HAD STABLE DISEASE. PLASMA AZACITIDINE WAS ONLY BRIEFLY DETECTABLE IN PATIENTS TREATED AT THE HIGHER DOSES. MOREOVER, IN 2 OF 3 PARTICIPANTS WHO AGREED AND UNDERWENT PRE- AND POST-TREATMENT BRONCHOSCOPY, THE GLOBAL DNA METHYLATION IN THE BRONCHIAL EPITHELIUM DECREASED BY 24 % AND 79 % POST-THERAPY, RESPECTIVELY. THE INTERVAL BETWEEN LAST INHALED TREATMENT AND BRONCHOSCOPY WAS 3 DAYS. CONCLUSIONS: INHALED AZACITIDINE RESULTED IN NEGLIGIBLE PLASMA LEVELS COMPARED TO THE PREVIOUSLY REPORTED SUBCUTANEOUS ADMINISTRATION AND WAS WELL-TOLERATED. THE RESULTS JUSTIFY THE CONTINUED DEVELOPMENT OF INHALED AZACITIDINE AT NON-CYTOTOXIC DOSES FOR PATIENTS WITH LUNG-CONFINED MALIGNANT AND/OR PREMALIGNANT LESIONS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
6  5613  62 SAFETY AND EFFICACY OF ABEXINOSTAT, A PAN-HISTONE DEACETYLASE INHIBITOR, IN NON-HODGKIN LYMPHOMA AND CHRONIC LYMPHOCYTIC LEUKEMIA: RESULTS OF A PHASE II STUDY. HISTONE DEACETYLASE INHIBITORS ARE MEMBERS OF A CLASS OF EPIGENETIC DRUGS THAT HAVE PROVEN ACTIVITY IN T-CELL MALIGNANCIES, BUT LITTLE IS KNOWN ABOUT THEIR EFFICACY IN B-CELL LYMPHOMAS. ABEXINOSTAT IS AN ORALLY AVAILABLE HYDROXAMATE-CONTAINING HISTONE DEACETYLASE INHIBITOR THAT DIFFERS FROM APPROVED INHIBITORS; ITS UNIQUE PHARMACOKINETIC PROFILE AND ORAL DOSING SCHEDULE, TWICE DAILY FOUR HOURS APART, ALLOWS FOR CONTINUOUS EXPOSURE AT CONCENTRATIONS REQUIRED TO EFFICIENTLY KILL TUMOR CELLS. IN THIS PHASE II STUDY, PATIENTS WITH RELAPSED/REFRACTORY NON-HODGKIN LYMPHOMA OR CHRONIC LYMPHOCYTIC LEUKEMIA RECEIVED ORAL ABEXINOSTAT AT 80 MG BID FOR 14 DAYS OF A 21-DAY CYCLE AND CONTINUED UNTIL PROGRESSIVE DISEASE OR UNACCEPTABLE TOXICITY. A TOTAL OF 100 PATIENTS WITH B-CELL MALIGNANCIES AND T-CELL LYMPHOMAS WERE ENROLLED BETWEEN OCTOBER 2011 AND JULY 2014. ALL PATIENTS RECEIVED AT LEAST ONE DOSE OF STUDY DRUG. PRIMARY REASONS FOR DISCONTINUATION INCLUDED PROGRESSIVE DISEASE (56%) AND ADVERSE EVENTS (25%). GRADE 3 OR OVER ADVERSE EVENTS AND ANY SERIOUS ADVERSE EVENTS WERE REPORTED IN 88% AND 73% OF PATIENTS, RESPECTIVELY. THE MOST FREQUENTLY REPORTED GRADE 3 OR OVER TREATMENT-EMERGENT RELATED ADVERSE EVENTS WERE THROMBOCYTOPENIA (80%), NEUTROPENIA (27%), AND ANEMIA (12%). AMONG THE 87 PATIENTS EVALUABLE FOR EFFICACY, OVERALL RESPONSE RATE WAS 28% (COMPLETE RESPONSE 5%), WITH HIGHEST RESPONSES OBSERVED IN PATIENTS WITH FOLLICULAR LYMPHOMA (OVERALL RESPONSE RATE 56%), T-CELL LYMPHOMA (OVERALL RESPONSE RATE 40%), AND DIFFUSE LARGE B-CELL LYMPHOMA (OVERALL RESPONSE RATE 31%). FURTHER INVESTIGATION OF THE SAFETY AND EFFICACY OF ABEXINOSTAT IN FOLLICULAR LYMPHOMA, T-CELL LYMPHOMA, AND DIFFUSE LARGE B-CELL LYMPHOMA IMPLEMENTING A LESS DOSE-INTENSE WEEK-ON-WEEK-OFF SCHEDULE IS WARRANTED.

7  3179  49 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.

8  5044  46 PHARMACOKINETICS AND PHARMACODYNAMICS WITH EXTENDED DOSING OF CC-486 IN PATIENTS WITH HEMATOLOGIC MALIGNANCIES. CC-486 (ORAL AZACITIDINE) IS AN EPIGENETIC MODIFIER IN DEVELOPMENT FOR PATIENTS WITH MYELODYSPLASTIC SYNDROMES AND ACUTE MYELOID LEUKEMIA. IN PART 1 OF THIS TWO-PART STUDY, A 7-DAY CC-486 DOSING SCHEDULE SHOWED CLINICAL ACTIVITY, WAS GENERALLY WELL TOLERATED, AND REDUCED DNA METHYLATION. EXTENDING DOSING OF CC-486 BEYOND 7 DAYS WOULD INCREASE DURATION OF AZACITIDINE EXPOSURE. WE HYPOTHESIZED THAT EXTENDED DOSING WOULD THEREFORE PROVIDE MORE SUSTAINED EPIGENETIC ACTIVITY. REPORTED HERE ARE THE PHARMACOKINETIC (PK) AND PHARMACODYNAMIC (PD) PROFILES OF CC-486 EXTENDED DOSING SCHEDULES IN PATIENTS WITH MYELODYSPLASTIC SYNDROMES (MDS), CHRONIC MYELOMONOCYTIC LEUKEMIA (CMML) OR ACUTE MYELOID LEUKEMIA (AML) FROM PART 2 OF THIS STUDY. PK AND/OR PD DATA WERE AVAILABLE FOR 59 PATIENTS WHO WERE SEQUENTIALLY ASSIGNED TO 1 OF 4 EXTENDED CC-486 DOSING SCHEDULES: 300MG ONCE-DAILY OR 200MG TWICE-DAILY FOR 14 OR 21 DAYS PER 28-DAY CYCLE. BOTH 300MG ONCE-DAILY SCHEDULES AND THE 200MG TWICE-DAILY 21-DAY SCHEDULE SIGNIFICANTLY (ALL P < .05) REDUCED GLOBAL DNA METHYLATION IN WHOLE BLOOD AT ALL MEASURED TIME POINTS (DAYS 15, 22, AND 28 OF THE TREATMENT CYCLE), WITH SUSTAINED HYPOMETHYLATION AT CYCLE END COMPARED WITH BASELINE. CC-486 EXPOSURES AND REDUCED DNA METHYLATION WERE SIGNIFICANTLY CORRELATED. PATIENTS WHO HAD A HEMATOLOGIC RESPONSE HAD SIGNIFICANTLY GREATER METHYLATION REDUCTIONS THAN NON-RESPONDING PATIENTS. THESE DATA DEMONSTRATE THAT EXTENDED DOSING OF CC-486 SUSTAINS EPIGENETIC EFFECTS THROUGH THE TREATMENT CYCLE.

9  2769  57 EXTENDED DOSING WITH CC-486 (ORAL AZACITIDINE) IN PATIENTS WITH MYELOID MALIGNANCIES. CC-486 (ORAL AZACITIDINE) IS AN EPIGENETIC MODIFIER IN CLINICAL DEVELOPMENT FOR TREATMENT OF HEMATOLOGICAL CANCERS. THIS STUDY OF EXTENDED CC-486 DOSING INCLUDED PATIENTS WITH MYELODYSPLASTIC SYNDROMES (MDSS), CHRONIC MYELOMONOCYTIC LEUKEMIA (CMML), OR ACUTE MYELOID LEUKEMIA (AML). AFTER A PHARMACOKINETIC ASSESSMENT PERIOD, 31 PATIENTS (MDS N = 18, CMML N = 4, AND AML N = 9) ENTERED A CLINICAL PHASE IN WHICH THEY RECEIVED CC-486 300 MG ONCE-DAILY FOR 21 DAYS OF REPEATED 28-DAY CYCLES. MEDIAN AGE WAS 71 YEARS (RANGE: 53-93); 42% OF PATIENTS WERE AGED >/=75 YEARS. A TOTAL OF 5 PATIENTS WITH AML (63%) HAD PRIOR MDS. MEDIAN NUMBER OF CC-486 TREATMENT CYCLES WAS 4 (RANGE: 1-32). THE MOST COMMON TREATMENT-EMERGENT ADVERSE EVENTS (TEAES) WERE GASTROINTESTINAL (84% OF PATIENTS) AND HEMATOLOGIC (81%). MOST COMMON GRADE 3-4 TEAES WERE NEUTROPENIA (N = 13, 42%) AND ANEMIA (N = 9, 29%). TEN PATIENTS EXPERIENCED GRADE 4 NEUTROPENIA. INFREQUENTLY, CC-486 DOSE WAS INTERRUPTED OR REDUCED DUE TO GASTROINTESTINAL (N = 5, 16%) OR HEMATOLOGIC (N = 6, 19%) TEAES. OVERALL RESPONSE RATE (COMPLETE REMISSION [CR], CR WITH INCOMPLETE HEMATOLOGICAL RECOVERY [CRI], PARTIAL REMISSION [PR], MARROW CR) IN THE MDS/CMML SUBGROUPS WAS 32% AND IN THE AML SUBGROUP (CR/CRI/PR) WAS 22%. RED BLOOD CELL TRANSFUSION INDEPENDENCE RATES IN THE MDS/CMML AND AML SUBGROUPS WERE 33% AND 25%, RESPECTIVELY, AND 2 MDS/CMML PATIENTS ATTAINED HEMATOLOGIC IMPROVEMENT AS A BEST RESPONSE ON-STUDY. NO BASELINE GENE MUTATION WAS PREDICTIVE OF RESPONSE/NONRESPONSE. CC-486 ALLOWS FLEXIBLE DOSING AND SCHEDULES TO IMPROVE TOLERABILITY OR RESPONSE. NEUTROPENIA IN EARLY TREATMENT CYCLES DESERVES SCRUTINY AND MAY WARRANT INITIATION OF PROPHYLACTIC ANTIBIOTICS. KEY POINTS: THE SAFETY PROFILE OF ORAL CC-486 WAS COMPARABLE TO THAT OF INJECTABLE AZACITIDINE; MOST ADVERSE EVENTS WERE HEMATOLOGICAL AND GASTROINTESTINAL. EXTENDED (21-DAY/CYCLE) CC-486 DOSING INDUCED RESPONSES IN PATIENTS WITH HEMATOLOGICAL MALIGNANCIES, MANY OF WHOM HAD PRIOR DNMTI FAILURE.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
10  1785  47 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
11  5056  45 PHASE I TRIAL OF LOW DOSE DECITABINE TARGETING DNA HYPERMETHYLATION IN PATIENTS WITH CHRONIC LYMPHOCYTIC LEUKAEMIA AND NON-HODGKIN LYMPHOMA: DOSE-LIMITING MYELOSUPPRESSION WITHOUT EVIDENCE OF DNA HYPOMETHYLATION. TARGETING ABERRANT DNA HYPERMETHYLATION IN CHRONIC LYMPHOCYTIC LEUKAEMIA (CLL) AND NON-HODGKIN LYMPHOMA (NHL) WITH DECITABINE MAY REVERSE EPIGENETIC SILENCING IN B-CELL MALIGNANCIES. TWENTY PATIENTS WERE ENROLLED IN TWO PHASE I TRIALS TO DETERMINE THE MINIMUM EFFECTIVE PHARMACOLOGICAL DOSE OF DECITABINE IN PATIENTS WITH RELAPSED/REFRACTORY CLL (N = 16) AND NHL (N = 4). PATIENTS RECEIVED 1-3 CYCLES OF DECITABINE. DOSE-LIMITING TOXICITY (DLT) WAS OBSERVED IN 2 OF 4 CLL AND 2 OF 2 NHL PATIENTS RECEIVING DECITABINE AT 15 MG/M(2) PER D DAYS 1-10, CONSISTING OF GRADE 3-4 THROMBOCYTOPENIA AND HYPERBILIRUBINAEMIA. SIX PATIENTS WITH CLL RECEIVED DECITABINE AT 10 MG/M(2) PER D DAYS 1-10 WITHOUT DLT; HOWEVER, RE-EXPRESSION OF METHYLATED GENES OR CHANGES IN GLOBAL DNA METHYLATION WERE NOT OBSERVED. THEREFORE, A 5-DAY DECITABINE SCHEDULE WAS EXAMINED. WITH 15 MG/M(2) PER D DECITABINE DAYS 1-5, DLT OCCURRED IN 2 OF 6 CLL AND 2 OF 2 NHL PATIENTS, CONSISTING OF GRADE 3-4 NEUTROPENIA, THROMBOCYTOPENIA, AND FEBRILE NEUTROPENIA. EIGHT PATIENTS HAD STABLE DISEASE. IN 17 PATIENTS, THERE WERE NO SIGNIFICANT CHANGES IN GENOME-WIDE METHYLATION OR IN TARGET GENE RE-EXPRESSION. IN CONCLUSION, DOSE-LIMITING MYELOSUPPRESSION AND INFECTIOUS COMPLICATIONS PREVENTED DOSE ESCALATION OF DECITABINE TO LEVELS ASSOCIATED WITH CHANGES IN GLOBAL METHYLATION OR GENE RE-EXPRESSION IN CLL AND NHL.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
12  5283  48 PROPHYLACTIC OR PREEMPTIVE LOW-DOSE AZACITIDINE AND DONOR LYMPHOCYTE INFUSION TO PREVENT DISEASE RELAPSE FOLLOWING ALLOGENEIC TRANSPLANTATION IN PATIENTS WITH HIGH-RISK ACUTE MYELOGENOUS LEUKEMIA OR MYELODYSPLASTIC SYNDROME. BECAUSE OF THE PERSISTENTLY HIGH RATES OF RELAPSE OF PATIENTS WITH HIGH-RISK ACUTE MYELOGENOUS LEUKEMIA (AML) AND MYELODYSPLASTIC SYNDROME (MDS) FOLLOWING ALLOGENEIC HEMATOPOIETIC STEM CELL TRANSPLANTATION (ALLO-HSCT), POST-TRANSPLANTATION MAINTENANCE THERAPY HAS BEEN PROPOSED. WE PREVIOUSLY INITIATED A PHASE II TRIAL IN WHICH EPIGENETIC THERAPY WAS COMBINED WITH IMMUNOTHERAPY IN AN ATTEMPT TO REDUCE DISEASE RELAPSE. IN THAT STUDY, LOW-DOSE AZACITIDINE (AZA) AND ESCALATING DOSES OF DONOR LYMPHOCYTE INFUSION (DLI) WERE GIVEN AS POST-ALLO-HSCT MAINTENANCE TREATMENT. IN THE PRESENT STUDY, WE RETROSPECTIVELY ANALYZE A LARGER COHORT OF PATIENTS RECEIVING POST-TRANSPLANTATION MAINTENANCE THERAPY AND PROVIDE UPDATES ON SOME PATIENTS OF THE EARLIER STUDY. THE OBJECTIVES OF THE PRESENT STUDY WERE TO ANALYZE THE CUMULATIVE INCIDENCE OF RELAPSE (CIR), OVERALL SURVIVAL (OS), AND PROGRESSION-FREE SURVIVAL (PFS) AND THE INCIDENCE OF ACUTE AND CHRONIC GRAFT-VERSUS-HOST DISEASE (GVHD) OF PATIENTS WITH HIGH-RISK AML OR MDS RECEIVING POST-TRANSPLANTATION MAINTENANCE TREATMENT WITH AZA WITH OR WITHOUT DLI. WE RETROSPECTIVELY ANALYZED 77 PATIENTS (54 WITH AML, 23 WITH MDS) CONSIDERED AT HIGH RISK BASED ON EITHER THEIR GENOMIC OR CLINICAL STATUS AT TRANSPLANTATION. FOLLOWING ALLOGENEIC TRANSPLANTATION, THEY RECEIVED AT LEAST 1 CYCLE OF PROPHYLACTIC OR PREEMPTIVE LOW-DOSE AZA WITH OR WITHOUT ESCALATING DOSES OF DLI TO PREVENT DISEASE RELAPSE. ALMOST ONE-HALF OF THE PATIENTS (47%) WERE ABLE TO RECEIVE THE FULL 12 CYCLES OF SCHEDULED AZA, AND A MAJORITY (79%) RECEIVED AT LEAST 1 DLI. WITH A MEDIAN FOLLOW-UP OF 24 MONTHS, 19 PATIENTS (25%; 16 WITH AML, 3 WITH MDS) RELAPSED, AT A MEDIAN OF 9.8 MONTHS (RANGE, 4 TO 58.6 MONTHS), GIVING A 22% CIR AT 24 MONTHS. OS AND PFS AT 24 MONTHS WERE 70.8% AND 68.3%, RESPECTIVELY. THE CUMULATIVE INCIDENCES OF GRADE II-IV ACUTE GVHD AND CHRONIC GVHD WERE 27.4% AND 45%, RESPECTIVELY. ONLY A MINORITY OF PATIENTS (11%) REQUIRED DELAYED ADMINISTRATION OF AZA. THESE FINDINGS CONFIRM THAT AZA-DLI MAINTENANCE IS BOTH TOLERABLE AND EFFECTIVE IN REDUCING THE RISK OF POST-TRANSPLANTATION RELAPSE.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
13  6418  47 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
14   745  60 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	

15  1956  57 EPIGENETIC AGE IN PERIPHERAL BLOOD AMONG CHILDREN, ADOLESCENT, AND ADULT SURVIVORS OF CHILDHOOD CANCER. IMPORTANCE: CERTAIN CANCER THERAPIES ARE RISK FACTORS FOR EPIGENETIC AGE ACCELERATION (EAA) AMONG SURVIVORS OF CHILDHOOD CANCER, AND EAA IS ASSOCIATED WITH CHRONIC HEALTH CONDITIONS (CHCS). HOWEVER, SMALL NUMBERS OF YOUNGER SURVIVORS (AGED <20 YEARS) PREVIOUSLY EVALUATED HAVE LIMITED THE ABILITY TO CALCULATE EAA AMONG THIS AGE GROUP. OBJECTIVE: TO EVALUATE THE CHANGE RATE OF EPIGENETIC AGE (EA) AND EAA IN YOUNGER COMPARED WITH OLDER SURVIVORS AND THE POSSIBLE ASSOCIATION OF EAA WITH EARLY-ONSET OBESITY (AGED <20 YEARS), SEVERITY/BURDEN OF CHCS, AND LATE MORTALITY (>5 YEARS FROM CANCER DIAGNOSIS). DESIGN, SETTING, AND PARTICIPANTS: STUDY PARTICIPANTS WERE FROM THE ST JUDE LIFETIME COHORT, INITIATED IN 2007 WITH ONGOING FOLLOW-UP. THE PRESENT STUDY WAS CONDUCTED FROM APRIL 17, 2022, TO MARCH 23, 2023. SURVIVORS IN THIS COHORT OF EUROPEAN ANCESTRY WITH DNA METHYLATION DATA WERE INCLUDED. CROSS-SECTIONAL ANNUAL CHANGES IN EA AND EAA WERE COMPARED ACROSS 5 DIFFERENT CHRONOLOGIC AGE GROUPS: AGE 0 TO 9 (CHILDREN), 10 TO 19 (ADOLESCENTS), 20 TO 34 (YOUNGER ADULTS), 35 TO 49 (MIDDLE-AGED ADULTS), AND GREATER THAN OR EQUAL TO 50 (OLDER ADULTS) YEARS. LOGISTIC REGRESSION EVALUATED THE ASSOCIATION BETWEEN EAA AND EARLY-ONSET OBESITY OR SEVERITY/BURDEN OF CHCS. COX PROPORTIONAL HAZARDS REGRESSION ASSESSED THE ASSOCIATION BETWEEN EAA AND LATE MORTALITY. MAIN OUTCOMES AND MEASURES: EARLY-ONSET OBESITY, SEVERITY/BURDEN OF CHCS (GRADED USING THE COMMON TERMINOLOGY CRITERIA FOR ADVERSE EVENTS (GRADE 1, MILD; 2, MODERATE; 3, SEVERE/DISABLING; 4, LIFE-THREATENING) AND WERE COMBINED INTO HIGH VS LOW SEVERITY/BURDEN BASED ON FREQUENCY AND GRADE), AND LATE MORTALITY WERE THE OUTCOMES BASED ON FOLLOW-UP UNTIL APRIL 2020. EXPANDED DNA METHYLATION PROFILING INCREASED THE NUMBER OF SURVIVORS YOUNGER THAN 20 YEARS (N = 690). EPIGENETIC AGE WAS CALCULATED PRIMARILY USING THE LEVINE CLOCK, AND EAA WAS DERIVED FROM LEAST SQUARES REGRESSION OF EA AGAINST CHRONOLOGIC AGE AND WAS STANDARDIZED TO A Z SCORE (LEVINE EEA). RESULTS: AMONG 2846 PARTICIPANTS (MEDIAN AGE, 30.3 [IQR, 9.3-41.5] YEARS; 53% MALES), THE CROSS-SECTIONAL ANNUAL CHANGE IN EA_LEVINE WAS HIGHER IN CHILDREN (1.63 YEARS) AND ADOLESCENTS (1.14 YEARS), AND THE ADJUSTED LEAST-SQUARES MEAN OF LEVINE EEA WAS LOWER IN CHILDREN (-0.22 YEARS) AND OLDER ADULTS (-1.70 YEARS). EACH 1-SD INCREASE IN LEVINE EEA WAS ASSOCIATED WITH INCREASED RISK OF DEVELOPING EARLY-ONSET OBESITY (ODDS RATIO [OR], 1.46; 95% CI, 1.19-1.78), HIGH SEVERITY/BURDEN OF CHCS (OR, 1.13; 95% CI, 1.03-1.24), AND LATE MORTALITY (HAZARD RATIO, 1.75; 95% CI, 1.35-2.26). CONCLUSIONS AND RELEVANCE: THE FINDINGS OF THIS STUDY SUGGEST THAT EAA MEASURED IN CHILDREN AND ADOLESCENT SURVIVORS OF CHILDHOOD CANCER IS ASSOCIATED WITH EARLY-ONSET OBESITY, SEVERITY/BURDEN OF ALL CHCS, AND LATE MORTALITY. EVALUATING EAA MAY HELP IDENTIFY SURVIVORS OF CHILDHOOD CANCER AT INCREASED RISK FOR EARLY-ONSET OBESITY, MORBIDITY IN GENERAL, AND MORTALITY.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
16  2464  72 EPIGENETIC THERAPY USING BELINOSTAT FOR PATIENTS WITH UNRESECTABLE HEPATOCELLULAR CARCINOMA: A MULTICENTER PHASE I/II STUDY WITH BIOMARKER AND PHARMACOKINETIC ANALYSIS OF TUMORS FROM PATIENTS IN THE MAYO PHASE II CONSORTIUM AND THE CANCER THERAPEUTICS RESEARCH GROUP. PURPOSE: EPIGENETIC ABERRATIONS HAVE BEEN REPORTED IN HEPATOCELLULAR CARCINOMA (HCC). IN THIS STUDY OF PATIENTS WITH UNRESECTABLE HCC AND CHRONIC LIVER DISEASE, EPIGENETIC THERAPY WITH THE HISTONE DEACETYLASE INHIBITOR BELINOSTAT WAS ASSESSED. THE OBJECTIVES WERE TO DETERMINE DOSE-LIMITING TOXICITY AND MAXIMUM-TOLERATED DOSE (MTD), TO ASSESS PHARMACOKINETICS IN PHASE I, AND TO ASSESS ACTIVITY OF AND EXPLORE POTENTIAL BIOMARKERS FOR RESPONSE IN PHASE II. PATIENTS AND METHODS: MAJOR ELIGIBILITY CRITERIA INCLUDED HISTOLOGICALLY CONFIRMED UNRESECTABLE HCC, EUROPEAN COOPERATIVE ONCOLOGY GROUP PERFORMANCE SCORE </= 2, AND ADEQUATE ORGAN FUNCTION. PHASE I CONSISTED OF 18 PATIENTS; BELINOSTAT WAS GIVEN INTRAVENOUSLY ONCE PER DAY ON DAYS 1 TO 5 EVERY 3 WEEKS; DOSE LEVELS WERE 600 MG/M(2) PER DAY (LEVEL 1), 900 MG/M(2) PER DAY (LEVEL 2), 1,200 MG/M(2) PER DAY (LEVEL 3), AND 1,400 MG/M(2) PER DAY (LEVEL 4). PHASE II CONSISTED OF 42 PATIENTS. THE PRIMARY END POINT WAS PROGRESSION-FREE SURVIVAL (PFS), AND THE MAIN SECONDARY END POINTS WERE RESPONSE ACCORDING TO RESPONSE EVALUATION CRITERIA IN SOLID TUMORS (RECIST) AND OVERALL SURVIVAL (OS). EXPLORATORY ANALYSIS WAS CONDUCTED ON PRETREATMENT TUMOR TISSUES TO DETERMINE WHETHER HR23B EXPRESSION IS A POTENTIAL BIOMARKER FOR RESPONSE. RESULTS: BELINOSTAT PHARMACOKINETICS WERE LINEAR FROM 600 TO 1,400 MG/M(2) WITHOUT SIGNIFICANT ACCUMULATION. THE MTD WAS NOT REACHED AT THE MAXIMUM DOSE ADMINISTERED. DOSE LEVEL 4 WAS USED IN PHASE II. THE MEDIAN NUMBER OF CYCLES WAS TWO (RANGE, ONE TO 12). THE PARTIAL RESPONSE (PR) AND STABLE DISEASE (SD) RATES WERE 2.4% AND 45.2%, RESPECTIVELY. THE MEDIAN PFS AND OS WERE 2.64 AND 6.60 MONTHS, RESPECTIVELY. EXPLORATORY ANALYSIS REVEALED THAT DISEASE STABILIZATION RATE (COMPLETE RESPONSE PLUS PR PLUS SD) IN TUMORS HAVING HIGH AND LOW HR23B HISTOSCORES WERE 58% AND 14%, RESPECTIVELY (P = .036). CONCLUSION: EPIGENETIC THERAPY WITH BELINOSTAT DEMONSTRATES TUMOR STABILIZATION AND IS GENERALLY WELL-TOLERATED. HR23B EXPRESSION WAS ASSOCIATED WITH DISEASE STABILIZATION.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
17   846  43 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
18   821  35 CHARACTERIZATION OF ACETYLATION OF HISTONE H3 AT LYSINE 9 IN THE TRIGEMINAL GANGLION OF A RAT TRIGEMINAL NEURALGIA MODEL. TRIGEMINAL NEURALGIA (TN) IS A CHRONIC NEUROPATHIC PAIN DISORDER CHARACTERIZED BY SPONTANEOUS AND ELICITED PAROXYSMS OF ELECTRIC-SHOCK-LIKE OR STABBING PAIN IN A REGION OF THE FACE. THE EPIGENETIC REGULATION OF TN IS STILL OBSCURE. IN CURRENT STUDY, A RAT TN MODEL SUBJECT TO CARBAMAZEPINE (CBZ) TREATMENT WAS ESTABLISHED, AND TRANSCRIPTOME- AND GENOME-SCALE PROFILING OF H3K9AC AND HDAC3 WAS PERFORMED BY RNA-SEQ AND CHIP-SEQ. WE OBSERVED THAT H3K9AC LEVELS IN THE TRIGEMINAL GANGLION WERE LOWER IN THE TN RATS COMPARED WITH THOSE IN THE CONTROL, AND CBZ TREATMENT LED TO RECOVERY OF H3K9AC LEVELS. FURTHER, WE FOUND THAT HDAC3 WAS OVERACTIVATED, WHICH INTERFERED WITH H3K9 ACETYLATION DUE TO HIGHER PHOSPHORYLATION IN TN COMPARED WITH THAT IN THE CONTROL. FINALLY, THE PHOSPHOKINASE LEUCINE-RICH REPEAT KINASE 2 (LRRK2) WAS DEMONSTRATED TO CONTRIBUTE TO HDAC3 ACTIVITY VIA THE MAPK SIGNALING PATHWAY. TAKEN TOGETHER, WE IDENTIFIED A REGULATORY MECHANISM IN WHICH THE PHOSPHATE GROUPS TRANSFERRED FROM ACTIVATED ERK AND LRRK2 TO HDAC3 CAUSED GENOME-SCALE DEACETYLATION AT H3K9 AND RESULTED IN THE SILENCING OF A LARGE NUMBER OF GENES IN TN. THE KINASES OR IMPORTANT ENZYMES WITHIN THIS REGULATORY AXIS MAY REPRESENT IMPORTANT TARGETS FOR TN THERAPY AND PREVENTION.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
19  3850  37 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
