1  5725 178 SKIN MANIFESTATIONS OF INSULIN RESISTANCE: FROM A BIOCHEMICAL STANCE TO A CLINICAL DIAGNOSIS AND MANAGEMENT. WORLDWIDE, MORE THAN 1.9 BILLION ADULTS ARE OVERWEIGHT, AND AROUND 600 MILLION PEOPLE SUFFER FROM OBESITY. SIMILARLY, ~382 MILLION INDIVIDUALS LIVE WITH DIABETES, AND 40-50% OF THE GLOBAL POPULATION IS LABELED AT "HIGH RISK" (I.E., PREDIABETES). THE IMPACT OF THESE TWO CHRONIC CONDITIONS RELIES NOT ONLY ON THE BURDEN OF ILLNESSES PER SE (I.E., ASSOCIATED INCREASED MORBIDITY AND MORTALITY), BUT ALSO ON THEIR INCREASED COST, BURDEN OF TREATMENT, AND DECREASED HEALTH-RELATED QUALITY OF LIFE. FOR THIS REVIEW A COMPREHENSIVE SEARCH IN SEVERAL DATABASES INCLUDING PUBMED (MEDLINE), OVID EMBASE, WEB OF SCIENCE, AND SCOPUS WAS CONDUCTED. IN BOTH DIABETES AND OBESITY, GENETIC, EPIGENETIC, AND ENVIRONMENTAL FACTORS OVERLAP AND ARE INCLUSIVE RATHER THAN EXCLUSIVE. DE FACTO, 70-80% OF THE PATIENTS WITH OBESITY AND VIRTUALLY EVERY PATIENT WITH TYPE 2 DIABETES HAVE INSULIN RESISTANCE. INSULIN RESISTANCE IS A WELL-KNOWN PATHOPHYSIOLOGIC FACTOR IN THE DEVELOPMENT OF TYPE 2 DIABETES, CHARACTERISTICALLY APPEARING YEARS BEFORE ITS DIAGNOSIS. THE GOLD STANDARD FOR INSULIN RESISTANCE DIAGNOSIS (THE EUGLYCEMIC INSULIN CLAMP) IS A COMPLEX, INVASIVE, COSTLY, AND HENCE UNFEASIBLE TEST TO IMPLEMENT IN CLINICAL PRACTICE. LIKEWISE, LABORATORY MEASURES AND DERIVED INDEXES [E.G., HOMEOSTASIS MODEL ASSESSMENT OF INSULIN RESISTANCE (HOMA-IR-)] ARE INDIRECT, IMPRECISE, AND NOT HIGHLY ACCURATE AND REPRODUCIBLE TESTS. HOWEVER, SKIN MANIFESTATIONS OF INSULIN RESISTANCE (E.G., ACROCHORDONS, ACANTHOSIS NIGRICANS, ANDROGENETIC ALOPECIA, ACNE, HIRSUTISM) OFFER A RELIABLE, STRAIGHTFORWARD, AND REAL-TIME WAY TO DETECT INSULIN RESISTANCE. THE OBJECTIVE OF THIS REVIEW IS TO AID CLINICIANS IN RECOGNIZING SKIN MANIFESTATIONS OF INSULIN RESISTANCE. DIAGNOSING THESE SKIN MANIFESTATIONS ACCURATELY MAY CASCADE POSITIVELY IN THE PATIENT'S HEALTH BY TRIGGERING AN ADEQUATE METABOLIC EVALUATION, A TIMELY TREATMENT OR REFERRAL WITH THE ULTIMATE OBJECTIVE OF DECREASING DIABETES AND OBESITY BURDEN, AND IMPROVING THE HEALTH AND THE QUALITY OF CARE FOR THESE PATIENTS.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
2  3395  42 HOST GENETIC FACTORS PREDISPOSING TO HIV-ASSOCIATED NEUROCOGNITIVE DISORDER. THE SUCCESS OF COMBINATION ANTIRETROVIRAL THERAPY (CART) IN TRANSFORMING THE LIVES OF HIV-INFECTED INDIVIDUALS WITH ACCESS TO THESE DRUGS IS TEMPERED BY THE INCREASING THREAT OF HIV-ASSOCIATED NEUROCOGNITIVE DISORDERS (HAND) TO THEIR OVERALL HEALTH AND QUALITY OF LIFE. INTENSIVE INVESTIGATIONS OVER THE PAST TWO DECADES HAVE UNDERSCORED THE ROLE OF HOST IMMUNE RESPONSES, INFLAMMATION, AND MONOCYTE-DERIVED MACROPHAGES IN HAND, BUT THE PRECISE PATHOGENIC MECHANISMS UNDERLYING HAND REMAIN ONLY PARTIALLY DELINEATED. COMPLICATING RESEARCH EFFORTS AND THERAPEUTIC DRUG DEVELOPMENT ARE THE SHEER COMPLEXITY OF HAND PHENOTYPES, DIAGNOSTIC IMPRECISION, AND THE GROWING INTERSECTION OF CHRONIC IMMUNE ACTIVATION WITH AGING-RELATED COMORBIDITIES. YET, GENETIC STUDIES STILL OFFER A POWERFUL MEANS OF ADVANCING INDIVIDUALIZED CARE FOR HIV-INFECTED INDIVIDUALS AT RISK. THERE IS AN URGENT NEED FOR 1) LONGITUDINAL STUDIES USING CONSISTENT PHENOTYPIC DEFINITIONS OF HAND IN HIV-INFECTED SUBPOPULATIONS AT VERY HIGH RISK OF BEING ADVERSELY IMPACTED, SUCH AS CHILDREN, 2) TISSUE STUDIES THAT CORRELATE NEUROPATHOLOGICAL CHANGES IN MULTIPLE BRAIN REGIONS WITH GENOMIC MARKERS IN AFFECTED INDIVIDUALS AND WITH CHANGES AT THE RNA, EPIGENOMIC, AND/OR PROTEIN LEVELS, AND 3) GENETIC ASSOCIATION STUDIES USING MORE SENSITIVE SUBPHENOTYPES OF HAND. THE NIH BRAIN INITIATIVE AND HUMAN CONNECTOME PROJECT, COUPLED WITH RAPIDLY EVOLVING SYSTEMS BIOLOGY AND MACHINE LEARNING APPROACHES FOR ANALYZING HIGH-THROUGHPUT GENETIC, TRANSCRIPTOMIC AND EPIGENETIC DATA, HOLD PROMISE FOR IDENTIFYING ACTIONABLE BIOLOGICAL PROCESSES AND GENE NETWORKS THAT UNDERLIE HAND. THIS REVIEW SUMMARIZES THE CURRENT STATE OF UNDERSTANDING OF HOST GENETIC FACTORS PREDISPOSING TO HAND IN LIGHT OF PAST CHALLENGES AND SUGGESTS SOME PRIORITIES FOR FUTURE RESEARCH TO ADVANCE THE UNDERSTANDING AND CLINICAL MANAGEMENT OF HAND IN THE CART ERA.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
3  3272  38 HEPATOCELLULAR CARCINOMA: AN UPDATE. HEPATOCELLULAR CARCINOMA (HCC) IS THE MOST COMMON MALIGNANT TUMOR OF MALES IN THE WORLD, WITH AN INCIDENCE OF 1,000,000 NEW CASES A YEAR. IT IS ENDEMIC IN SOUTHEAST ASIA AND SUB-SAHARAN AFRICA. RISK FACTORS INCLUDE CHRONIC INFECTION WITH HEPATITIS B VIRUS (HBV) AND HEPATITIS C VIRUS (HCV), AFLATOXIN B1 UPTAKE, HEMOCHROMATOSIS, AND ALPHA1 -ANTITRIPSIN DEFICIENCY. EPIDEMIOLOGICAL STUDIES PROVIDE EVIDENCE FOR THE ASSOCIATION OF HCC WITH HBV INFECTION. THE INCIDENCE OF HCC IS HIGH IN REGIONS HYPERENDEMIC FOR HBV. CHRONIC CARRIER STATE AND MATERNAL-INFANT TRANSMISSION ARE IMPORTANT FACTORS IN THE DEVELOPMENT OF HCC. EVIDENCE OF DIRECT ONCOGENIC EFFECT OF H BV IS WELL ESTABLISHED, HCCS CONTAIN VIRAL DNA SEQUENCES INTEGRATED INTO HEPATOCYTE DNA THAT ACT AS RANDOM INSERTIONAL MUTAGENS, AND THESE SITES ARE NEAR GENES INVOLVED IN THE CONTROL OF PROLIFERATION AND DIFFERENTIATION. THE MECHANISM OF HEPATITIS C VIRUS IN HEPATOCARCINOGENESIS IS STILL IMPRECISE BUT A HIGH PERCENTAGE OF CASES ARE RELATED TO THIS VIRUS. CHRONIC ALCOHOL CONSUMPTION AND CIRRHOSIS ARE COFACTORS THAT INCREASE THE DEVELOPMENT OF HCC IN PATIENTS WITH CHRONIC VIRAL INFECTION. IN EXPERIMENTAL CARCINOGENESIS A MULTIPOTENTIAL ELEMENT CALLED OVAL CELL PROLIFERATES IN THE EARLY STAGES. THE CELLULAR EVENTS ARE ACCOMPANIED BY INCREASED EXPRESSION OF SEVERAL GROWTH FACTORS THAT ENHANCE THE SURVIVAL OF CARCINOGEN-ACTIVATED CELLS BY SUPPRESSING APOPTOSIS AND INCREASING ELEMENTS ENTERING THE CELL CYCLE. HEPATIC CARCINOGENESIS IS A COMPLEX PROCESS ASSOCIATED WITH ACCUMULATION OF GENETIC AND EPIGENETIC CHANGES THAT RUN THROUGH STEPS OF INITIATION, PROMOTION AND PROGRESSION. ACTIVATION OF ONCOGENES OF THE "RAS" FAMILY AND OTHERS HAS BEEN DETECTED DURING CHEMICALLY-INDUCED HCC IN RODENTS, BUT THERE IS LITTLE EVIDENCE OF SUCH ACTIVATION IN HUMAN TUMORS. THE ROLE OF TUMOR SUPRESSOR GENES SUCH AS RETINOBLASTOMA (RB) AND P53 GENES HAS BEEN DOCUMENTED. AFLATOXIN B1 THAT CONTAMINATES FOODS IN ENDEMIC AREAS HAS A CLEAR ROLE IN HEPATOCARCINOGENESIS. METABOLITES OF THIS TOXIN PROMOTE APURINIC SITES AND G TO T MUTATIONS IN CHROMOSOMAL DNA, THE THIRD BASE OF CODON 249 OF THE P53 GENE IS PREFERENTIALLY TARGETED TO FORM ADUCTS WITH AFLATOXIN B1, AND THIS MUTATION HAS BEEN SPECIFICALLY IDENTIFIED IN HBV INFECTION. HISTOLOGICAL AND CYTOLOGICAL CRITERIA FOR THE DIAGNOSIS OF HCC ARE WELL ESTABLISHED AND ARE BASED IN ARCHITECTURAL AND CYTOLOGICAL CHANGES. AN IMPORTANT ISSUE IS THE DIAGNOSIS OF LIVER "NODULES" DETECTED BY IMAGE, FROM WHICH SMALL BIOPSIES OR ASPIRATION MATERIAL IS OBTAINED. SPECIAL STUDIES SUCH AS RETICULIN, CD34, CYTOKERATIN PROFILE, AND MOC-31 CAN BE VERY USEFUL FOR THE DIFFERENTIAL DIAGNOSIS OF PRIMARY AND METASTATIC TUMORS. TELOMERASE ACTIVITY HAS BEEN FOUND IN HCC AND NEGATIVE IN PERICANCEROUS TISSUE. IT IS MORE PRONOUNCED IN POORLY DIFFERENTIATED TUMORS AND CORRELATES WITH FACTORS OF CLINICAL IMPORTANCE, SUCH AS PROGNOSIS AND RECURRENCES. CELLS OF WELL-DIFFERENTIATED HCC HAVE AN ULTRASTRUCTURAL APPEARANCE SIMILAR TO NORMAL HEPATOCYTES. DURING THE PROCESS OF DEDIFFERENTIATION, THERE IS PROGRESSIVE LOSS OF ORGANIZATION OF INTRACELLULAR ORGANELLES. THE CELL COHESION IS LOST, INTERCELLULAR GAPS WITH MICROVILLI APPEAR, THE SINUSOIDS BECOME CAPILLARIZED, AND REPARATIVE CHANGES ARE SEEN IN THE SPACES OF DISSE. A VARIETY OF INCLUSIONS, SUCH AS MALLORY BODIES, GRANULAR MATERIAL, SECONDARY LYSOSOMES, AND DUBIN-JOHNSON PIGMENT, HAVE BEEN DESCRIBED. FIBROLAMELLAR CARCINOMA HAS A CHARACTERISTIC HISTOLOGICAL PICTURE AND ULTRASTRUCTURALLY ONCOCYTIC FEATURES. NEUROENDOCRINE GRANULES AND COMBINATION OF HCC WITH BILE DUCT CARCINOMA ARE SEEN BY ELECTRON MICROSCOPY.	2001	
                                                                                                                                                                                                                                         
4  6742  41 WHITHER THE ETIOPATHOGENESIS (AND SCOLIOGENY) OF ADOLESCENT IDIOPATHIC SCOLIOSIS? ALTHOUGH CONSIDERABLE PROGRESS HAD BEEN MADE IN THE PAST TWO DECADES IN UNDERSTANDING THE ETIOPATHOGENESIS OF ADOLESCENT IDIOPATHIC SCOLIOSIS (AIS), IT STILL LACKS AN AGREED THEORY OF ETIOPATHOGENESIS. ONE PROBLEM MAY BE THAT AIS RESULTS NOT FROM ONE CAUSE, BUT SEVERAL THAT INTERACT WITH VARIOUS GENETIC PREDISPOSING FACTORS. THERE IS A VIEW THERE ARE TWO OTHER PATHOGENIC PROCESSES FOR IDIOPATHIC SCOLIOSIS NAMELY, INITIATING (OR INDUCING), AND THOSE THAT CAUSE CURVE PROGRESSION. TWIN STUDIES AND OBSERVATIONS OF FAMILY AGGREGATION HAVE REVEALED SIGNIFICANT GENETIC CONTRIBUTIONS TO IDIOPATHIC SCOLIOSIS, THAT PLACE AIS AMONG OTHER COMMON DISEASE OR COMPLEX TRAITS WITH A HIGH HERITABILITY INTERPRETED BY THE GENETIC VARIANT HYPOTHESIS OF DISEASE. WE SUMMARIZE ETIOPATHOGENETIC KNOWLEDGE OF AIS AS THEORIES OF PATHOGENESIS INCLUDING RECENT MULTIPLE CONCEPTS, AND BLOOD TESTS FOR AIS BASED ON PREDICTIVE BIOMARKERS AND GENETIC VARIANTS THAT SIGNIFY DISEASE RISK. THERE IS INCREASING EVIDENCE FOR THE POSSIBILITY OF AN UNDERLYING NEUROLOGICAL DISORDER FOR AIS, RESEARCH WHICH HOLDS PROMISE. LIKE BRAIN RESEARCH, MOST AIS WORKERS FOCUS ON THEIR OWN CORNER AND THERE IS A NEED FOR GREATER INTEGRATION OF RESEARCH EFFORT. EPIGENETICS, A RELATIVELY RECENT FIELD, EVALUATES FACTORS CONCERNED WITH GENE EXPRESSION IN RELATION TO ENVIRONMENT, DISEASE, NORMAL DEVELOPMENT AND AGING, WITH A COMPLEX REGULATION ACROSS THE GENOME DURING THE FIRST DECADE OF LIFE. RESEARCH ON THE ROLE OF ENVIRONMENTAL FACTORS, EPIGENETICS AND CHRONIC NON-COMMUNICABLE DISEASES (NCDS) INCLUDING ADIPOSITY, AFTER A SLOW START, HAS EXPLODED IN THE LAST DECADE. NOT SO FOR AIS RESEARCH AND THE ENVIRONMENT WHERE, EXCEPT FOR MONOZYGOTIC TWIN STUDIES, THERE ARE ONLY SPORADIC REPORTS TO SUGGEST THAT ENVIRONMENTAL FACTORS ARE AT WORK IN ETIOLOGY. HERE, WE EXAMINE EPIGENETIC CONCEPTS AS THEY MAY RELATE TO HUMAN DEVELOPMENT, NORMAL LIFE HISTORY PHASES AND AIS PATHOGENESIS.

5  6743  44 WHITHER THE ETIOPATHOGENESIS (AND SCOLIOGENY) OF ADOLESCENT IDIOPATHIC SCOLIOSIS? INCORPORATING PRESENTATIONS ON SCOLIOGENY AT THE 2012 IRSSD AND SRS MEETINGS. THIS PAPER AIMS TO INTEGRATE INTO CURRENT UNDERSTANDING OF AIS CAUSATION, ETIOPATHOGENETIC INFORMATION PRESENTED AT TWO MEETINGS DURING 2012 NAMELY, THE INTERNATIONAL RESEARCH SOCIETY OF SPINAL DEFORMITIES (IRSSD) AND THE SCOLIOSIS RESEARCH SOCIETY (SRS). THE ULTIMATE HOPE IS TO PREVENT THE OCCURRENCE OR PROGRESSION OF THE SPINAL DEFORMITY OF AIS WITH NON-INVASIVE TREATMENT, POSSIBLY MEDICAL. THIS MIGHT BE ATTAINED BY PERSONALISED POLYMECHANISTIC PREVENTIVE THERAPY TARGETING THE APPROPRIATE ETIOLOGY AND/OR ETIOPATHOGENETIC PATHWAYS, TO AVOID FUSION AND MAINTAIN SPINAL MOBILITY. ALTHOUGH CONSIDERABLE PROGRESS HAD BEEN MADE IN THE PAST TWO DECADES IN UNDERSTANDING THE ETIOPATHOGENESIS OF ADOLESCENT IDIOPATHIC SCOLIOSIS (AIS), IT STILL LACKS AN AGREED THEORY OF ETIOPATHOGENESIS. ONE PROBLEM MAY BE THAT AIS RESULTS NOT FROM ONE CAUSE, BUT SEVERAL THAT INTERACT WITH VARIOUS GENETIC PREDISPOSING FACTORS. THERE IS A VIEW THERE ARE TWO OTHER PATHOGENIC PROCESSES FOR IDIOPATHIC SCOLIOSIS NAMELY, INITIATING (OR INDUCING), AND THOSE THAT CAUSE CURVE PROGRESSION. TWIN STUDIES AND OBSERVATIONS OF FAMILY AGGREGATION HAVE REVEALED SIGNIFICANT GENETIC CONTRIBUTIONS TO IDIOPATHIC SCOLIOSIS, THAT PLACE AIS AMONG OTHER COMMON DISEASE OR COMPLEX TRAITS WITH A HIGH HERITABILITY INTERPRETED BY THE GENETIC VARIANT HYPOTHESIS OF DISEASE. WE SUMMARIZE ETIOPATHOGENETIC KNOWLEDGE OF AIS AS THEORIES OF PATHOGENESIS INCLUDING RECENT MULTIPLE CONCEPTS, AND BLOOD TESTS FOR AIS BASED ON PREDICTIVE BIOMARKERS AND GENETIC VARIANTS THAT SIGNIFY DISEASE RISK. THERE IS INCREASING EVIDENCE FOR THE POSSIBILITY OF AN UNDERLYING NEUROLOGICAL DISORDER FOR AIS, RESEARCH WHICH HOLDS PROMISE. LIKE BRAIN RESEARCH, MOST AIS WORKERS FOCUS ON THEIR OWN CORNER AND THERE IS A NEED FOR GREATER INTEGRATION OF RESEARCH EFFORT. EPIGENETICS, A RELATIVELY RECENT FIELD, EVALUATES FACTORS CONCERNED WITH GENE EXPRESSION IN RELATION TO ENVIRONMENT, DISEASE, NORMAL DEVELOPMENT AND AGING, WITH A COMPLEX REGULATION ACROSS THE GENOME DURING THE FIRST DECADE OF LIFE. RESEARCH ON THE ROLE OF ENVIRONMENTAL FACTORS, EPIGENETICS AND CHRONIC NON-COMMUNICABLE DISEASES (NCDS) INCLUDING ADIPOSITY, AFTER A SLOW START, HAS EXPLODED IN THE LAST DECADE. NOT SO FOR AIS RESEARCH AND THE ENVIRONMENT WHERE, EXCEPT FOR MONOZYGOTIC TWIN STUDIES, THERE ARE ONLY SPORADIC REPORTS TO SUGGEST THAT ENVIRONMENTAL FACTORS ARE AT WORK IN ETIOLOGY. HERE, WE EXAMINE EPIGENETIC CONCEPTS AS THEY MAY RELATE TO HUMAN DEVELOPMENT, NORMAL LIFE HISTORY PHASES AND AIS PATHOGENESIS. ALTHOUGH AIS IS NOT REGARDED AS AN NCD, LIKE THEM, IT IS ASSOCIATED WITH WHOLE ORGANISM METABOLIC PHENOMENA, INCLUDING LOWER BODY MASS INDEX, LOWER CIRCULATING LEPTIN LEVELS AND OTHER SYSTEMIC DISORDERS. SOME EPIGENETIC RESEARCH APPLIED TO SILVER-RUSSELL SYNDROME AND ADIPOSITY IS EXAMINED, FROM WHICH SUGGESTIONS ARE MADE FOR CONSIDERATION OF AIS EPIGENETIC RESEARCH, CROSS-SECTIONAL AND LONGITUDINAL.

6  4062  43 MATERNAL AND CHILD HEALTH SERVICES AND AN INTEGRATED, LIFE-CYCLE APPROACH TO THE PREVENTION OF NON-COMMUNICABLE DISEASES. DESCRIBED AS THE 'INVISIBLE EPIDEMIC', NON-COMMUNICABLE DISEASES (NCDS) ARE THE WORLD'S LEADING CAUSE OF DEATH. MOST ARE CAUSED BY PREVENTABLE FACTORS, INCLUDING POOR DIET, TOBACCO USE, HARMFUL USE OF ALCOHOL AND PHYSICAL INACTIVITY. DIABETES, CANCER AND CARDIOVASCULAR AND CHRONIC LUNG DISEASES WERE RESPONSIBLE FOR 38 MILLION (68%) OF GLOBAL DEATHS IN 2012. SINCE 1990, PROPORTIONATE NCD MORTALITY HAS INCREASED SUBSTANTIALLY AS POPULATIONS HAVE AGED AND COMMUNICABLE DISEASES DECLINE. THE MAJORITY OF NCD DEATHS, ESPECIALLY PREMATURE NCD DEATHS (<70 YEARS, 82%), OCCUR IN LOW-INCOME AND MIDDLE-INCOME COUNTRIES, AND AMONG POOR COMMUNITIES WITHIN THEM. ADDRESSING NCDS IS RECOGNISED AS CENTRAL TO THE POST-2015 AGENDA; ACCORDINGLY, NCDS HAVE A SPECIFIC OBJECTIVE AND TARGET IN THE SUSTAINABLE DEVELOPMENT GOALS. WHILE DEATHS FROM NCDS OCCUR MAINLY IN ADULTHOOD, MANY HAVE THEIR ORIGINS IN EARLY LIFE, INCLUDING THROUGH EPIGENETIC MECHANISMS OPERATING BEFORE CONCEPTION. GOOD NUTRITION BEFORE CONCEPTION AND INTERVENTIONS AIMED AT PREVENTING NCDS DURING THE FIRST 1000 DAYS (FROM CONCEPTION TO AGE 2 YEARS), CHILDHOOD AND ADOLESCENCE MAY BE MORE COST-EFFECTIVE THAN MANAGING ESTABLISHED NCDS IN LATER LIFE WITH COSTLY TESTS AND DRUGS. FOLLOWING A LIFE-COURSE APPROACH, MATERNAL AND CHILD HEALTH INTERVENTIONS, BEFORE DELIVERY AND DURING CHILDHOOD AND ADOLESCENCE, CAN PREVENT NCDS AND SHOULD INFLUENCE GLOBAL HEALTH AND SOCIOECONOMIC DEVELOPMENT. THIS PAPER DESCRIBES HOW SUCH AN APPROACH MAY BE PURSUED, INCLUDING THROUGH THE ENGAGEMENT OF NON-HEALTH SECTORS. IT ALSO EMPHASISES EVALUATING AND DOCUMENTING RELATED INITIATIVES TO UNDERWRITE SYSTEMATIC AND EVIDENCE-BASED CROSS-SECTORAL ENGAGEMENT ON NCD PREVENTION IN THE FUTURE.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
7   734  38 CANCER HEALTHCARE DISPARITIES AMONG AFRICAN AMERICANS IN THE UNITED STATES. A NEED EXISTS TO EXAMINE RACIAL DISPARITIES IN THE HEALTHCARE ARENA AND THE IMPACT ON PATIENTS WITH CANCER. DESPITE ONGOING EFFORTS TO INCREASE EQUITY IN PRIMARY HEALTHCARE ACCESS, RACIAL AND SOCIOECONOMIC DISPARITIES PERSIST, THUS CONTRIBUTING TO DISPROPORTIONATE TREATMENT OUTCOMES AND SURVIVORSHIP AMONG MINORITY AND LOW-INCOME PATIENTS. SUCH DISPARITIES HAVE BEEN REVEALED IN TREATMENT COHORTS OF PATIENTS WITH MULTIPLE FORMS OF CANCER, INCLUDING BREAST, CERVICAL, OVARIAN, ENDOMETRIAL, PROSTATE, LUNG, COLORECTAL, GASTROINTESTINAL, AND HEPATOCELLULAR, AND HAVE BEEN ATTRIBUTED TO A RANGE OF CO-OCCURRING BEHAVIORAL, SOCIAL DETERMINANTS OF HEALTH, UNDERLYING GENETIC FACTORS, AS WELL AS ACCESS TO EDUCATIONAL OPPORTUNITIES THAT LIMIT THE QUALITY OF INFORMED HEALTHCARE. THESE VARIOUS INTERRELATED FACTORS WIDEN CANCER HEALTHCARE DISPARITIES SYNERGISTICALLY THROUGHOUT UNDERSERVED COMMUNITIES, AND THEIR INFLUENCE HAS BEEN AMPLIFIED BY THE CORONAVIRUS DISEASE 2019 (COVID-19) PANDEMIC. FUNDAMENTALLY, A LACK OF BASIC AND CLINICAL RESEARCH EXISTS THAT FAILS TO ADEQUATELY REFLECT DIVERSITY AND MINORITY INVOLVEMENT IN DRUG DEVELOPMENT. ALTHOUGH OVERCOMING THE OBSTACLES RESPONSIBLE FOR CHRONIC TREATMENT DISPARITIES IS A FORMIDABLE TASK, PROMISING MEANS OF ACHIEVING MORE UNIFORM QUALITY HEALTHCARE ARE BECOMING MORE CLEARLY ELUCIDATED. TO REDUCE DISEASE PROGRESSION, INCREASE OVERALL SURVIVAL, AND IMPROVE THE HEALTH OF VULNERABLE POPULATIONS, IT IS NECESSARY TO IDENTIFY AND FULLY DISCLOSE ENVIRONMENTAL, BIOLOGICAL, AND ANCESTRAL FACTORS THAT IMPACT THE RISK FOR CANCER; HEAL HISTORICAL FRACTURES WITHIN COMMUNITIES; AND INCREASE PARTICIPATION OF RACIAL AND ETHNIC MINORITIES IN SCREENING EFFORTS AND RESEARCH STUDIES. THIS REQUIRES DEVELOPING A SYSTEM OF JUSTICE AND TRUST BASED ON SPECIFIC, SOLUTION-ORIENTED GRASSROOTS COMMUNITY EFFORTS WORKING IN TANDEM WITH MEDICAL AND PHARMACEUTICAL LEADERS. BY FULLY EXPLORING AND PINPOINTING THE UNDERLYING CAUSES OF HEALTHCARE DISPARITIES, IT SHOULD BE POSSIBLE TO DEFINE STRATEGIES AND INTERVENTIONS MOST LIKELY TO TRANSFORM CANCER CARE. THE ULTIMATE GOAL IS UNDERSTANDING INDIVIDUAL, CULTURAL, AND BIOLOGICAL VULNERABILITIES, INCLUDING ENVIRONMENTAL AND EPIGENETIC LIABILITIES, TO OPTIMIZE CANCER PREVENTION, DIAGNOSIS, AND TREATMENT.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
8    30  47 A BRIEF LOOK AT HASHIMOTO'S DISEASE, ADRENAL INCIDENTALOMAS, OBESITY AND INSULIN RESISTANCE-COULD ENDOCRINE DISRUPTORS BE THE OTHER SIDE OF THE SAME COIN? HASHIMOTO'S DISEASE (HD) IS THE MOST COMMON CAUSE OF HYPOTHYROIDISM IN DEVELOPED COUNTRIES. THE EXACT PATHOMECHANISM BEHIND IT HAS NOT BEEN CLEARLY ESTABLISHED; HOWEVER, AN INTERPLAY OF GENETIC SUSCEPTIBILITY, ENVIRONMENTAL TRIGGERS (INCLUDING DIET) AND EPIGENETIC FACTORS SEEMS TO BE INVOLVED. AMONG THE LATTER, INCREASINGLY MORE ATTENTION HAS BEEN PAID TO SOME HORMONALLY ACTIVE SUBSTANCES, KNOWN AS ENDOCRINE DISRUPTORS, WHICH ARE COMMONLY USED WORLDWIDE. HD HAS BECOME A CONDITION WIDELY REPORTED IN THE MEDIA, ACTING AS A CULPRIT FOR INEXPLICABLE WEIGHT GAIN, CHRONIC FATIGUE OR WEAKNESS. NEVERTHELESS, THE RECOGNITION OF HD IS UNDENIABLY INCREASING AND REPRESENTS A MAJOR PUBLIC HEALTH BURDEN. AT THE SAME TIME, IMPROVING ACCESS TO IMAGING TESTS HAS INCREASED THE NUMBER OF INCIDENTALLY DIAGNOSED ADRENAL TUMORS. ABOVE ALL, THE WIDESPREAD USE OF CHEST COMPUTED TOMOGRAPHY (CT) DUE TO THE COVID-19 PANDEMIC HAS CONTRIBUTED TO FREQUENT INCIDENTAL DETECTION OF ADRENAL LESIONS. FORTUNATELY, A VAST MAJORITY OF THESE FINDINGS ARE ASYMPTOMATIC BENIGN TUMORS WITH NO EXCESSIVE HORMONAL ACTIVITY, AND THEREFORE, THEY ARE DEFINED AS ADRENAL INCIDENTALOMAS (AIS). INTERESTINGLY, RECENT STUDIES HAVE INDICATED THAT PATIENTS WITH AIS ARE MORE PRONE TO OBESITY AND INSULIN RESISTANCE. ALTHOUGH MUTUAL RELATIONSHIPS BETWEEN THE THYROID AND THE ADRENAL GLANDS HAVE BEEN STUDIED WIDELY, STILL, LITTLE IS KNOWN ABOUT THE POSSIBLE PATHOPHYSIOLOGICAL ASSOCIATIONS BETWEEN THYROID AUTOIMMUNITY AND THE OCCURRENCE OF ADRENAL INCIDENTALOMAS. THIS ARTICLE PRESENTS A BRIEF REVIEW OF THE COMMON ENDOCRINE DISORDERS WITH A SPECIAL FOCUS ON THE FREQUENTLY COEXISTING INSULIN RESISTANCE AND/OR OBESITY. FURTHERMORE, IN RESPONSE TO THE RECENT GROWING INTEREST IN ENDOCRINE DISRUPTORS, WITH THEIR TRANSGENERATIONAL EPIGENETIC EFFECTS THAT INFLUENCE HORMONAL SYSTEM FUNCTION, A CONCISE OVERVIEW OF THE TOPIC HAS ALSO BEEN INCLUDED.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
9  1942  39 EPIDEMIOLOGY OF LIVER CANCER IN AFRICA: CURRENT AND FUTURE TRENDS. HEPATOCELLULAR CARCINOMA (HCC) IS A DISEASE OF GLOBAL PUBLIC HEALTH SIGNIFICANCE WITH MORTALITY ON THE RISE, DESPITE THE PREVENTABLE NATURE OF ITS RISK FACTORS ESPECIALLY IN AFRICA. IT IS NOW THE SIXTH MOST COMMON CANCER WORLDWIDE, FIFTH IN MALES, AND NINTH IN FEMALES. HCC INCIDENCE AND MORTALITY ARE PREDICTED TO INCREASE IN AFRICAN COUNTRIES CONSTRAINED BY LIMITED RESOURCES TO COMBAT ENDEMIC LEVELS OF VIRAL INFECTION AND SYNERGISTIC ENVIRONMENTAL RISK FACTORS. THE CHANGING NATURE OF HCC ETIOLOGY IS PARTICULARLY ILLUSTRATED HERE WITH THE TRADITIONAL RISK FACTORS LIKE VIRAL HEPATITIS COEXISTING ALONGSIDE HIGH HUMAN IMMUNODEFICIENCY VIRUS (HIV) PREVALENCE AND RAPIDLY INCREASING URBANIZATION THAT HAVE PROMOTED A SHARP INCREASE IN ADDITIONAL RISK FACTORS LIKE COINFECTION, TYPE 2 DIABETES MELLITUS, AND OBESITY. ALTHOUGH THERE ARE SOME DIFFERENCES IN ETIOLOGY BETWEEN NORTH AFRICA AND SUB-SAHARAN AFRICA, RISK FACTORS LIKE CHRONIC VIRAL HEPATITIS B AND C, AFLATOXIN EXPOSURE, AND IRON OVERLOAD PREDOMINATE. AGGRESSIVE HEPATITIS B GENOTYPES, COMBINED WITH HEPATITIS B VIRUS/HEPATITIS C VIRUS/HIV COINFECTIONS AND AFLATOXIN EXPOSURE, PROMOTE A MORE AGGRESSIVE MOLECULAR PHENOTYPE. IN PARALLEL TO A BETTER UNDERSTANDING OF THE MOLECULAR ETIOLOGY OF HCC, POLICY AND PLANNING INITIATIVES TO ADDRESS THE BURDEN OF HCC MUST BE ANCHORED WITHIN THE REALITY OF THE LIMITED RESOURCES AVAILABLE. ESTABLISHMENT AND COORDINATION OF CANCER REGISTRIES ACROSS AFRICA IS NEEDED TO IMPROVE THE QUALITY OF DATA NECESSARY TO GALVANIZE ACTION. PREVENTIVE MEASURES INCLUDING HEPATITIS B VACCINATION PROGRAMS, MEASURES TO PREVENT MATERNAL-TO-CHILD AND CHILD-TO-CHILD TRANSMISSION, DELIVERY OF UNIVERSALLY ACCESSIBLE ANTIRETROVIRAL AND ANTIVIRAL TREATMENTS, AND REDUCTION OF DIETARY AFLATOXIN EXPOSURE CAN CONTRIBUTE MARKEDLY TO REDUCE HCC INCIDENCE. FINALLY, THE DEVELOPMENT OF BIOMARKERS AND NEW THERAPEUTIC INTERVENTIONS WILL NEED A BETTER UNDERSTANDING OF THE UNIQUE GENETIC AND EPIGENETIC CHARACTERISTICS OF HCC ON THE CONTINENT. WE PRESENT A NARRATIVE REVIEW OF HCC IN AFRICA, DISCUSSING PRESENT AND FUTURE TRENDS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
10  6406  36 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
11  3630  45 INCLUSION OF SOCIAL AND STRUCTURAL DETERMINANTS OF HEALTH TO ADVANCE UNDERSTANDING OF THEIR INFLUENCE ON THE BIOLOGY OF CHRONIC DISEASE. SOCIAL DETERMINANTS OF HEALTH (SDOH) CONSIDER SOCIAL, POLITICAL, AND ECONOMIC FACTORS THAT CONTRIBUTE TO HEALTH DISPARITIES IN PATIENTS AND POPULATIONS. THE MOST COMMON HEALTH-RELATED SDOH EXPOSURES ARE FOOD AND HOUSING INSECURITY, FINANCIAL INSTABILITY, TRANSPORTATION NEEDS, LOW LEVELS OF EDUCATION, AND PSYCHOSOCIAL STRESS. THESE DOMAINS DESCRIBE RISKS THAT CAN IMPACT HEALTH OUTCOMES MORE THAN HEALTH CARE. EPIDEMIOLOGIC AND TRANSLATIONAL RESEARCH DEMONSTRATES THAT SDOH FACTORS REPRESENT EXPOSURES THAT PREDICT HARM AND IMPACT THE HEALTH OF INDIVIDUALS. INTERNATIONAL AND NATIONAL GUIDELINES URGE HEALTH PROFESSIONALS TO ADDRESS SDOH IN CLINICAL PRACTICE AND PUBLIC HEALTH. THE FURTHER IMPLEMENTATION OF THESE RECOMMENDATIONS INTO BASIC AND TRANSLATIONAL RESEARCH, HOWEVER, IS LAGGING. HEREIN, WE CONSIDER A PRECISION HEALTH FRAMEWORK TO DESCRIBE HOW SDOH CONTRIBUTES TO THE EXPOSOME AND EXACERBATES PHYSIOLOGIC PATHWAYS THAT LEAD TO CHRONIC DISEASE. SDOH FACTORS ARE ASSOCIATED WITH VARIOUS FORMS OF STRESSORS THAT IMPACT PHYSIOLOGICAL PROCESSES THROUGH EPIGENETIC, INFLAMMATORY, AND REDOX REGULATION. MANY SDOH EXPOSURES MAY ADD TO OR POTENTIATE THE PATHOLOGIC EFFECTS OF ADDITIONAL ENVIRONMENTAL EXPOSURES. THIS OVERVIEW AIMS TO INFORM BASIC LIFE SCIENCE AND TRANSLATIONAL RESEARCHERS ABOUT SDOH EXPOSURES THAT CAN CONFOUND ASSOCIATIONS BETWEEN CLASSIC BIOMEDICAL DETERMINANTS OF DISEASE AND HEALTH OUTCOMES. TO ADVANCE THE STUDY OF TOXICOLOGY THROUGH EITHER QUALITATIVE OR QUANTITATIVE ASSESSMENT OF EXPOSURES TO CHEMICAL AND BIOLOGICAL SUBSTANCES, A MORE COMPLETE ENVIRONMENTAL EVALUATION SHOULD INCLUDE SDOH EXPOSURES. WE DISCUSS COMMON APPROACHES TO MEASURE SDOH FACTORS AT INDIVIDUAL AND POPULATION LEVELS AND REVIEW THE ASSOCIATIONS BETWEEN SDOH RISK FACTORS AND PHYSIOLOGIC MECHANISMS THAT INFLUENCE CHRONIC DISEASE.

12  5179  39 PREGNANCY: AN UNDERUTILIZED WINDOW OF OPPORTUNITY TO IMPROVE LONG-TERM MATERNAL AND INFANT HEALTH-AN APPEAL FOR CONTINUOUS FAMILY CARE AND INTERDISCIPLINARY COMMUNICATION. PHYSIOLOGIC ADAPTATIONS DURING PREGNANCY UNMASK A WOMAN'S PREDISPOSITION TO DISEASES. COMPLICATIONS ARE INCREASINGLY PREDICTED BY FIRST-TRIMESTER ALGORITHMS, AMPLIFY A PRE-EXISTING MATERNAL PHENOTYPE AND ACCELERATE RISKS FOR CHRONIC DISEASES IN THE OFFSPRING UP TO ADULTHOOD (BARKER HYPOTHESIS). RECENT EVIDENCE SUGGESTS THAT VICE VERSA, PREGNANCY DISEASES ALSO INDICATE MATERNAL AND EVEN GRANDPARENT'S RISKS FOR CHRONIC DISEASES (REVERSE BARKER HYPOTHESIS). PUB-MED AND EMBASE WERE REVIEWED FOR MESH TERMS "FETAL PROGRAMMING" AND "PREGNANCY COMPLICATIONS COMBINED WITH MATERNAL DISEASE" UNTIL JANUARY 2017. STUDIES LINKING PREGNANCY COMPLICATIONS TO FUTURE CARDIOVASCULAR, METABOLIC, AND THROMBOTIC RISKS FOR MOTHER AND OFFSPRING WERE REVIEWED. WOMEN WITH A HISTORY OF MISCARRIAGE, FETAL GROWTH RESTRICTION, PREECLAMPSIA, PRETERM DELIVERY, OBESITY, EXCESSIVE GESTATIONAL WEIGHT GAIN, GESTATIONAL DIABETES, SUBFERTILITY, AND THROMBOPHILIA MORE FREQUENTLY DEMONSTRATE WITH ECHOCARDIOGRAPHIC ABNORMALITIES, HIGHER FASTING INSULIN, DEVIATING LIPIDS OR CLOTTING FACTORS AND SHOW DEFECTIVE ENDOTHELIAL FUNCTION. THROMBOPHILIA HINTS TO THROMBOTIC RISKS IN LATER LIFE. PREGNANCY ABNORMALITIES CORRELATE WITH FUTURE CARDIOVASCULAR AND METABOLIC COMPLICATIONS AND EARLIER MORTALITY. CONVERSELY, WOMEN WITH A NORMAL PREGNANCY HAVE LOWER RATES OF SUBSEQUENT DISEASES THAN THE GENERAL FEMALE POPULATION CREATING THE TERM: "PREGNANCY AS A WINDOW FOR FUTURE HEALTH." ALTHOUGH THE PLACENTA WORKS AS A GATEKEEPER, MANY PREGNANCY COMPLICATIONS MAY LEAD TO SICKNESS AND EARLIER DEATH IN LATER LIFE WHEN THE CHILD BECOMES AN ADULT. THE EPIGENETIC MECHANISMS AND THE MISMATCH BETWEEN PRE- AND POSTNATAL LIFE HAVE CREATED THE TERM "FETAL ORIGIN OF ADULT DISEASE." UP TO NOW, THE IMPACT OF CARDIOVASCULAR, METABOLIC, OR THROMBOTIC RISK PROFILES HAS BEEN INVESTIGATED SEPARATELY FOR MOTHER AND CHILD. IN THIS MANUSCRIPT, WE STRIVE TO ILLUSTRATE THE CONSEQUENCES FOR BOTH, FETUS AND MOTHER WITHIN A COHESIVE PERSPECTIVE AND THUS TRY TO DEMONSTRATE THE COMPLEX INTERRELATIONSHIP OF GENETICS AND EPIGENETICS FOR LONG-TERM HEALTH OF SOCIETIES AND FUTURE GENERATIONS. MATERNAL-FETAL MEDICINE SPECIALISTS SHOULD HAVE A KEY ROLE IN THE PREVENTION OF NON-COMMUNICABLE DISEASES BY IMPLEMENTING A FRAMEWORK FOR PATIENT CONSULTATION AND INTERDISCIPLINARY NETWORKS. HEALTH-CARE PROVIDERS AND POLICY MAKERS SHOULD INCREASINGLY INVEST IN A STRATIFIED PRIMARY PREVENTION AND FOLLOW-UP TO REDUCE THE INCREASING NUMBER OF MANIFEST CARDIOVASCULAR AND METABOLIC DISEASES AND TO PREVENT WASTE OF HEALTH-CARE RESOURCES.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
13  6631  40 UNDERSTANDING THE MANIFESTATION OF DIABETES IN SUB SAHARAN AFRICA TO INFORM THERAPEUTIC APPROACHES AND PREVENTIVE STRATEGIES: A NARRATIVE REVIEW. BACKGROUND: GLOBALLY, THE BURDEN OF DIABETES MELLITUS HAS INCREASED TO EPIDEMIC PROPORTIONS. ESTIMATES FROM THE INTERNATIONAL DIABETES FEDERATION PREDICT THAT THE GREATEST FUTURE INCREASE IN THE PREVALENCE OF DIABETES MELLITUS WILL OCCUR IN AFRICA. METHODS: THIS ARTICLE REVIEWS LITERATURE ON THE MANIFESTATION OF DIABETES IN ADULT PATIENTS IN SUB-SAHARAN AFRICA HIGHLIGHTING THE DISTINCT PHENOTYPES, PLAUSIBLE EXPLANATIONS FOR THIS UNIQUE MANIFESTATION AND THE CLINICAL SIGNIFICANCE OF COMPREHENSIVELY DEFINING AND UNDERSTANDING THE AFRICAN DIABETES PHENOTYPE. RESULTS: THERE ARE FEW STUDIES ON THE MANIFESTATION OR PHENOTYPE OF DIABETES IN AFRICA. THE LIMITED DATA AVAILABLE SUGGESTS THAT, COMPARED TO THE WESTERN WORLD, THE MAJORITY OF PATIENTS WITH DIABETES IN AFRICA ARE YOUNG AND RELATIVELY LEAN IN BODY SIZE. IN ADDITION, HYPERGLYCAEMIA IN MOST CASES IS CHARACTERISED BY A SIGNIFICANTLY BLUNTED ACUTE FIRST PHASE OF INSULIN SECRETION IN RESPONSE TO AN ORAL OR INTRAVENOUS GLUCOSE LOAD AND PANCREATIC BETA CELL SECRETORY DYSFUNCTION, RATHER THAN PERIPHERAL INSULIN RESISTANCE PREDOMINATES. GENETIC AND ENVIRONMENTAL FACTORS LIKE CHRONIC INFECTIONS/INFLAMMATION, EARLY LIFE MALNUTRITION AND EPIGENETIC MODIFICATIONS ARE THOUGHT TO CONTRIBUTE TO THESE DISTINCT DIFFERENCES IN MANIFESTATION. CONCLUSIONS: WHILE PUBLISHED DATA IS LIMITED, THERE APPEARS TO BE DISTINCT PHENOTYPES OF DIABETES IN SUB-SAHARAN AFRICA. LARGE AND MORE DETAILED STUDIES ARE NEEDED ESPECIALLY AMONG NEWLY DIAGNOSED PATIENTS TO FULLY CHARACTERIZE DIABETES IN THIS REGION. THIS WILL FURTHER IMPROVE THE UNDERSTANDING OF MANIFESTATION OF DIABETES AND GUIDE THE FORMULATION OF OPTIMAL THERAPEUTIC APPROACHES AND PREVENTIVE STRATEGIES OF THE CONDITION ON THE CONTINENT.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
14  4663  33 NEW HORIZONS: NOVEL APPROACHES TO ENHANCE HEALTHSPAN THROUGH TARGETING CELLULAR SENESCENCE AND RELATED AGING MECHANISMS. THE ELDERLY POPULATION IS INCREASING FASTER THAN OTHER SEGMENTS OF THE POPULATION THROUGHOUT THE WORLD. AGE IS THE LEADING PREDICTOR FOR MOST CHRONIC DISEASES AND DISORDERS, MULTIMORBIDITY, GERIATRIC SYNDROMES, AND IMPAIRED ABILITY TO RECOVER FROM ACCIDENTS OR ILLNESSES. ENHANCING THE DURATION OF HEALTH AND INDEPENDENCE, TERMED HEALTHSPAN, WOULD BE MORE DESIRABLE THAN EXTENDING LIFESPAN MERELY BY PROLONGING THE PERIOD OF MORBIDITY TOWARD THE END OF LIFE. THE GEROSCIENCE HYPOTHESIS POSITS THAT HEALTHSPAN CAN BE EXTENDED BY TARGETING FUNDAMENTAL AGING MECHANISMS, RATHER THAN ATTEMPTING TO ADDRESS EACH AGE-RELATED DISEASE ONE AT A TIME, ONLY SO THE AFFLICTED INDIVIDUAL SURVIVES DISABLED AND DIES SHORTLY AFTERWARD OF ANOTHER AGE-RELATED DISEASE. THESE FUNDAMENTAL AGING MECHANISMS INCLUDE, AMONG OTHERS, CHRONIC INFLAMMATION, FIBROSIS, STEM CELL/ PROGENITOR DYSFUNCTION, DNA DAMAGE, EPIGENETIC CHANGES, METABOLIC SHIFTS, DESTRUCTIVE METABOLITE GENERATION, MITOCHONDRIAL DYSFUNCTION, MISFOLDED OR AGGREGATED PROTEIN ACCUMULATION, AND CELLULAR SENESCENCE. THESE PROCESSES APPEAR TO BE TIGHTLY INTERLINKED, AS TARGETING ANY ONE APPEARS TO AFFECT MANY OF THE REST, UNDERLYING OUR UNITARY THEORY OF FUNDAMENTAL AGING MECHANISMS. INTERVENTIONS TARGETING MANY FUNDAMENTAL AGING PROCESSES ARE BEING DEVELOPED, INCLUDING DIETARY MANIPULATIONS, METFORMIN, MTOR (MECHANISTIC TARGET OF RAPAMYCIN) INHIBITORS, AND SENOLYTICS, WHICH ARE IN EARLY HUMAN TRIALS. THESE INTERVENTIONS COULD LEAD TO GREATER HEALTHSPAN BENEFITS THAN TREATING AGE-RELATED DISEASES ONE AT A TIME. TO ILLUSTRATE THESE POINTS, WE FOCUS ON CELLULAR SENESCENCE AND THERAPIES IN DEVELOPMENT TO TARGET SENESCENT CELLS. COMBINING INTERVENTIONS TARGETING AGING MECHANISMS WITH DISEASE-SPECIFIC DRUGS COULD RESULT IN MORE THAN ADDITIVE BENEFITS FOR CURRENTLY DIFFICULT-TO-TREAT OR INTRACTABLE DISEASES. MORE RESEARCH ATTENTION NEEDS TO BE DEVOTED TO TARGETING FUNDAMENTAL AGING PROCESSES.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
15   537  29 ASYMPTOMATIC HYPERURICEMIA: IS IT REALLY ASYMPTOMATIC? PURPOSE OF REVIEW: HYPERURICEMIA IS HIGHLY PREVALENT, AFFECTING APPROXIMATELY 38 MILLION INDIVIDUALS IN THE UNITED STATES. HOWEVER, THE SIGNIFICANCE OF ASYMPTOMATIC HYPERURICEMIA - HYPERURICEMIA IN THE ABSENCE OF GOUT - CONTINUES TO BE DEBATED. RECENT FINDINGS: ASYMPTOMATIC HYPERURICEMIA RESULTS IN MONOSODIUM URATE CRYSTAL DEPOSITION IN TISSUES, WHICH MAY PROMOTE CHRONIC INFLAMMATION. INTRACELLULARLY, HYPERURICEMIA INHIBITS THE MASTER REGULATOR ADENOSINE MONOPHOSPHATE (AMP)-ASSOCIATED PROTEIN KINASE AND MAY CONDITION INNATE IMMUNE RESPONSES THROUGH DURABLE EPIGENETIC MODIFICATIONS. AT THE POPULATION LEVEL, ASYMPTOMATIC HYPERURICEMIA IS ASSOCIATED WITH MULTIPLE COMORBIDITIES, INCLUDING HYPERTENSION, CHRONIC KIDNEY DISEASE, CORONARY ARTERY DISEASE, AND DIABETES; LIMITATIONS OF THESE STUDIES INCLUDE THAT MOST ARE RETROSPECTIVE AND SOME DO NOT RIGOROUSLY DISTINGUISH BETWEEN ASYMPTOMATIC HYPERURICEMIA AND GOUT. TREATMENT STUDIES SUGGEST THAT URATE LOWERING MAY REDUCE THE RISK OF INCIDENCE OR PROGRESSION OF SOME OF THESE COMORBIDITIES; UNFORTUNATELY, MANY OF THESE TREATMENT STUDIES ARE SMALL OR FLAWED, AND NOT ALL STUDY RESULTS ARE CONSISTENT. SUMMARY: ACCUMULATING EVIDENCE SUGGESTS THAT ASYMPTOMATIC HYPERURICEMIA CONTRIBUTES TO THE COMORBIDITIES WITH WHICH IT ASSOCIATES AND THAT PROPER ASYMPTOMATIC HYPERURICEMIA TREATMENT MAY REDUCE FUTURE RISK. ADDITIONAL PROSPECTIVE TRIALS ARE NEEDED TO DEFINITELY ESTABLISH CAUSALITY AND SUPPORT DECISION-MAKING AS TO WHETHER, AND WHICH PATIENTS WITH ASYMPTOMATIC HYPERURICEMIA WOULD WARRANT URATE-LOWERING TREATMENT.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
16  1737  44 EARLY DETECTION OF ACCELERATED AGING AND CELLULAR DECLINE (AACD): A CONSENSUS STATEMENT. THE CELLULAR HALLMARKS OF ACCELERATED AGING AND THEIR CLINICAL EXPRESSION MAY BE GROUPED USING THE TERMS 'ACCELERATED AGING AND CELLULAR DECLINE' (AACD) AND/OR 'AGE-ASSOCIATED CELLULAR DECLINE'. THIS CONSTRUCT IS DESIGNED TO CAPTURE THE BIOLOGICAL BACKGROUND PREDISPOSING THE DEVELOPMENT OF AGE-RELATED CONDITIONS. BY CLASSIFYING RISK FACTORS, EARLY INDICATORS, AND CLINICAL DIFFERENTIATORS OF AACD THROUGH EXPERT CONSENSUS, THIS STUDY AIMED TO IDENTIFY THE SIGNS, SYMPTOMS, AND MARKERS INDICATIVE OF AACD. IN DOING SO, THIS WORK PAVES THE WAY FOR FUTURE IMPLEMENTATION OF THE AACD CONCEPT IN THE CLINICAL AND RESEARCH SETTINGS. AN INTERDISCIPLINARY PANEL OF EXPERTS WITH CLINICAL AND RESEARCH EXPERTISE WAS SELECTED TO PARTICIPATE IN A VIRTUAL WORKSHOP TO DISCUSS AACD. A MODIFIED NOMINAL GROUP TECHNIQUE WAS USED TO ESTABLISH CONSENSUS AMONG THE GROUP. AN EXTENDED GROUP OF INTERNATIONAL EXPERTS CRITICALLY REVIEWED AN EARLY DRAFT OF THE MANUSCRIPT, AND THEIR FEEDBACK WAS THEN INCORPORATED INTO THE MODEL. EXPERTS IDENTIFIED 13 FACTORS PREDISPOSING TO OR CLINICALLY MANIFESTING AACD. AMONG THESE, CHRONIC DISEASES, OBESITY, AND UNFAVORABLE GENETIC BACKGROUND WERE CONSIDERED AS THE MOST IMPORTANT. THERE WAS A CONSENSUS THAT A GRADUAL AND NONSPECIFIC DEVELOPMENT OFTEN CHARACTERIZES AACD, MAKING ITS CLINICAL DETECTION POTENTIALLY CHALLENGING. IN ADDITION, SIGNS AND SYMPTOMS MIGHT HAVE MULTIFACTORIAL CAUSES AND OVERLAPPING ORIGINS, SUCH AS GENETIC AND EPIGENETIC PREDISPOSITIONS. AS A RESULT, AN INITIAL CHECKLIST WAS OUTLINED, LISTING CLINICAL FACTORS OF SPECIAL RELEVANCE (E.G., FATIGUE, LOW QUALITY OF SLEEP, AND LOW MOOD) TO REPRESENT EARLY MANIFESTATIONS OF THE ORGANISM'S EXHAUSTION, WHICH ARE ALSO FREQUENTLY NEGLECTED IN THE CLINICAL SETTING. DIFFERENTIATING AACD FROM OTHER CONDITIONS IS ESSENTIAL. THE USE OF A COMBINATION OF BIOMARKERS WAS PROPOSED AS A VIABLE METHOD IN A TWO-STEP PROCESS OF DIFFERENTIATION: 1) IDENTIFICATION OF EARLY AACD CLINICAL INDICATORS, FOLLOWED BY 2) SYMPTOM AND BIOMARKER CONFIRMATION WITH A FOCUS ON SYSTEM DOMAINS (TO BE POTENTIALLY TARGETED BY FUTURE SPECIFIC INTERVENTIONS). ALTHOUGH THE AACD CONSTRUCT IS NOT YET READY FOR ROUTINE USE IN CLINICAL PRACTICE, ITS OPERATIONALIZATION MAY SUPPORT THE EARLY IDENTIFICATION OF AGE-RELATED CONDITIONS (WHEN THIS MIGHT STILL BE AMENABLE TO REVERSION) AND ALSO ENCOURAGE PREVENTATIVE INTERVENTIONS. FURTHER INVESTIGATION IS NEEDED TO ESTABLISH SPECIFIC BIOMARKERS THAT CONFIRM INDEPENDENT RISK FACTORS FOR AACD AND PROVIDE A MORE DEFINITIVE STRUCTURE TO THE CONCEPT OF AACD (AND AGE-ASSOCIATED CELLULAR DECLINE).	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
17   529  30 ASTHMA IN URBAN CHILDREN: EPIDEMIOLOGY, ENVIRONMENTAL RISK FACTORS, AND THE PUBLIC HEALTH DOMAIN. ASTHMA IS THE MOST COMMONLY REPORTED CHRONIC CONDITION OF CHILDHOOD IN DEVELOPED COUNTRIES, WITH 6.5 MILLION CHILDREN AFFECTED IN THE USA. A DISPARATE BURDEN OF CHILDHOOD ASTHMA IS SEEN AMONG SOCIOECONOMICALLY DISADVANTAGED YOUTH, OFTEN CONCENTRATED IN URBAN AREAS WITH HIGH POVERTY RATES. HOST FACTORS THAT PREDISPOSE A CHILD TO ASTHMA INCLUDE ATOPY, MALE GENDER, PARENTAL HISTORY OF ASTHMA, AND ALSO RACE, ETHNICITY, AND GENETIC AND EPIGENETIC SUSCEPTIBILITIES. ENVIRONMENTAL FACTORS, SUCH AS IMPROVED HYGIENE, AMBIENT AIR POLLUTION, AND EARLY LIFE EXPOSURES TO MICROBES AND AEROALLERGENS, ALSO INFLUENCE THE DEVELOPMENT OF ASTHMA. WITH GREATER THAN 90% OF TIME SPENT INDOORS, HOME EXPOSURES (SUCH AS COCKROACH, RODENT, AND INDOOR AIR POLLUTION) ARE HIGHLY RELEVANT FOR URBAN ASTHMA. MORBIDITY REDUCTION MAY REQUIRE FOCUSED PUBLIC HEALTH INITIATIVES FOR ENVIRONMENTAL INTERVENTION IN HIGH PRIORITY RISK GROUPS AND THE ADDITION OF IMMUNE MODULATORY AGENTS IN CHILDREN WITH POORLY CONTROLLED DISEASE.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
18  3271  30 HEPATOCELLULAR CARCINOMA RISK AFTER VIRAL RESPONSE IN HEPATITIS C VIRUS-ADVANCED FIBROSIS: WHO TO SCREEN AND FOR HOW LONG? HEPATITIS C VIRUS (HCV) CHRONIC INFECTION IS ASSOCIATED WITH FIBROSIS PROGRESSION, END-STAGE LIVER COMPLICATIONS AND HCC. NOT SURPRISINGLY, HCV INFECTION IS A LEADING CAUSE OF LIVER-RELATED MORBIDITY AND MORTALITY WORLDWIDE. AFTER SUSTAINED VIROLOGICAL RESPONSE (SVR), THE RISK OF DEVELOPING HEPATOCELLULAR CARCINOMA IS NOT COMPLETELY ELIMINATED IN PATIENTS WITH ESTABLISHED CIRRHOSIS OR WITH ADVANCED FIBROSIS. THEREFORE, LIFELONG SURVEILLANCE IS CURRENTLY RECOMMENDED. THIS STRATEGY IS LIKELY NOT UNIVERSALLY COST-EFFECTIVE AND HARMLESS, CONSIDERING THAT NOT ALL PATIENTS WITH ADVANCED FIBROSIS HAVE THE SAME RISK OF DEVELOPING HCC. FACTORS RELATED TO THE SEVERITY OF LIVER DISEASE AND ITS POTENTIAL TO IMPROVE AFTER SVR, THE MOLECULAR AND EPIGENETIC CHANGES THAT OCCUR DURING INFECTION AND OTHER ASSOCIATED COMORBIDITIES MIGHT ACCOUNT FOR DIFFERENT RISK LEVELS AND ARE LIKELY ESSENTIAL FOR IDENTIFYING PATIENTS WHO WOULD BENEFIT FROM SCREENING PROGRAMS AFTER SVR. EFFORTS TO DEVELOP PREDICTIVE MODELS AND RISK CALCULATORS, BIOMARKERS AND GENETIC PANELS AND EVEN DEEP LEARNING MODELS TO ESTIMATE THE INDIVIDUAL RISK OF HCC HAVE BEEN MADE IN THE DIRECT-ACTING ANTIVIRAL AGENTS ERA, WHEN THOUSANDS OF PATIENTS WITH ADVANCED FIBROSIS AND CIRRHOSIS HAVE REACHED SVR. THESE TOOLS COULD HELP TO IDENTIFY PATIENTS WITH VERY LOW HCC RISK IN WHOM SURVEILLANCE MIGHT NOT BE JUSTIFIED. IN THIS REVIEW, FACTORS AFFECTING THE PROBABILITY OF HCC DEVELOPMENT AFTER SVR, THE BENEFITS AND RISKS OF SURVEILLANCE, SUGGESTED STRATEGIES TO ESTIMATE INDIVIDUALIZED HCC RISK AND THE CURRENT EVIDENCE TO RECOMMEND LIFELONG SURVEILLANCE ARE DISCUSSED.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
19  5025  33 PERSONALIZED MANAGEMENT OF CARDIOVASCULAR DISORDERS. PERSONALIZED MANAGEMENT OF CARDIOVASCULAR DISORDERS (CVD), ALSO REFERRED TO AS PERSONALIZED OR PRECISION CARDIOLOGY IN ACCORDANCE WITH GENERAL PRINCIPLES OF PERSONALIZED MEDICINE, IS SELECTION OF THE BEST TREATMENT FOR AN INDIVIDUAL PATIENT. IT INVOLVES THE INTEGRATION OF VARIOUS "OMICS" TECHNOLOGIES SUCH AS GENOMICS AND PROTEOMICS AS WELL AS OTHER NEW TECHNOLOGIES SUCH AS NANOBIOTECHNOLOGY. MOLECULAR DIAGNOSTICS AND BIOMARKERS ARE IMPORTANT FOR LINKING DIAGNOSIS WITH THERAPY AND MONITORING THERAPY. BECAUSE CVD INVOLVE PERTURBATIONS OF LARGE COMPLEX BIOLOGICAL NETWORKS, A SYSTEMS BIOLOGY APPROACH TO CVD RISK STRATIFICATION MAY BE USED FOR IMPROVING RISK-ESTIMATING ALGORITHMS, AND MODELING OF PERSONALIZED BENEFIT OF TREATMENT MAY BE HELPFUL FOR GUIDING THE CHOICE OF INTERVENTION. BIOINFORMATICS TOOLS ARE HELPFUL IN ANALYZING AND INTEGRATING LARGE AMOUNTS OF DATA FROM VARIOUS SOURCES. PERSONALIZED THERAPY IS CONSIDERED DURING DRUG DEVELOPMENT, INCLUDING METHODS OF TARGETED DRUG DELIVERY AND CLINICAL TRIALS. INDIVIDUALIZED RECOMMENDATIONS CONSIDER MULTIPLE FACTORS - GENETIC AS WELL AS EPIGENETIC - FOR PATIENTS' RISK OF HEART DISEASE. EXAMPLES OF PERSONALIZED TREATMENT ARE THOSE OF CHRONIC MYOCARDIAL ISCHEMIA, HEART FAILURE, AND HYPERTENSION. SIMILAR APPROACHES CAN BE USED FOR THE MANAGEMENT OF ATRIAL FIBRILLATION AND HYPERCHOLESTEROLEMIA, AS WELL AS THE USE OF ANTICOAGULANTS. PERSONALIZED MANAGEMENT INCLUDES PHARMACOTHERAPY, SURGERY, LIFESTYLE MODIFICATIONS, AND COMBINATIONS THEREOF. FURTHER PROGRESS IN UNDERSTANDING THE PATHOMECHANISM OF COMPLEX CARDIOVASCULAR DISEASES AND IDENTIFICATION OF CAUSATIVE FACTORS AT THE INDIVIDUAL PATIENT LEVEL WILL PROVIDE OPPORTUNITIES FOR THE DEVELOPMENT OF PERSONALIZED CARDIOLOGY. APPLICATION OF PRINCIPLES OF PERSONALIZED MEDICINE WILL IMPROVE THE CARE OF THE PATIENTS WITH CVD.	2017

FROM A DIAGNOSTIC POINT OF VIEW, THE PROPER CLASSIFICATION OF LIVER TUMORS INTO A BENIGN AND MALIGNANT CATEGORY HAS TO BE BASED ON THE DIRECT CORRELATION BETWEEN THE MORPHOLOGY AND THE BIOLOGIC BEHAVIOR OF THE LESIONS. THEREFORE, EXTREME CARE SHOULD BE TAKEN TO SEPARATE THE MALIGNANT TUMORS FROM THE BENIGN AND THE BENIGN NEOPLASIA FROM THE HYPERPLASIA. THE SUBSTITUTION OF THE TERM "NEOPLASTIC NODULE" FOR HYPERPLASTIC NODULE IN RATS IS MISLEADING. MOST OF THESE NODULES, WHEN INDUCED UNDER SPECIAL EXPERIMENTAL CONDITIONS, MAY REGRESS OR REMODEL AND THUS THEY ARE NOT NEOPLASTIC IN NATURE. CHRONIC CARCINOGENICITY BIOASSAYS SHOULD INCLUDE "STOP" TYPE OF TREATMENT LEAVING ENOUGH OF THE OBSERVATIONAL TIME TO ESTABLISH THE FATE OF INDUCED NODULAR LESIONS. THE INDUCTION OF HISTOCHEMICALLY CHANGED FOCI CAN SERVE ONLY AS AN INDICATION OF POTENTIAL HEPATOCARCINOGENICITY AND SHOULD NOT BE EQUATED WITH THE INDUCTION OF BONA FIDE CANCER. THE BIOLOGIC INTERPRETATION OF NODULAR LIVER LESIONS, ESPECIALLY IN MICE, NEEDS FURTHER SCRUTINY BECAUSE THESE LESIONS HAVE A TENDENCY TO DEVELOP SPONTANEOUSLY WITH HIGH INCIDENCE IN SOME STRAINS. THIS CHARACTERISTIC THEN RAISES THE QUESTION AS TO THE MECHANISM BY WHICH VARIOUS AGENTS AUGMENT AND/OR ACCELERATE THE DEVELOPMENT OF SUCH TUMORS. IS THIS ACTION PRIMARILY PROMOTING OR INITIATING IN NATURE OR DOES IT REPRESENT THE INDUCTION OF TUMORS DE NOVO? THE ANSWER TO THIS DILEMMA MAY HAVE A DECISIVE BEARING ON CARCINOGENIC RISK ASSESSMENT AND THE TYPE OF REGULATORY ACTION, SINCE THE PROMOTING AGENTS POSSESS A THRESHOLD EFFECT AND THE PROMOTED CHANGES MAY REGRESS FOLLOWING WITHDRAWAL OF TREATMENT. THE INTERPRETATION OF HEPATOCARCINOGENESIS IS FURTHER COMPLICATED BY THE FACT THAT SEVERAL FACTORS, SUCH AS SEX HORMONAL ENVIRONMENT, INCREASED MITOTIC ACTIVITY FOLLOWING AN EXCESSIVE LOSS OF PARENCHYMAL CELLS, DEGREE OF CALORIC INTAKE, ENZYMATIC COMPLEMENT, AND ANIMALS' AGE AT THE TIME OF THE EXPOSURE TO A TEST AGENT, MAY INFLUENCE THE OUTCOME OF LIVER TUMOR DEVELOPMENT BY MODULATING "INITIATION" AND/OR "PROMOTION" OF CARCINOGENESIS. BROAD FLUCTUATION IN THE HISTORIC INCIDENCE OF LIVER TUMORS FURTHER COMPOUNDS THE COMPLEXITY OF THE PROPER BIOASSAY INTERPRETATION. THE SPECIFICALLY DESIGNED EXPERIMENTS MAY HAVE THE OBJECTIVE TO EXPLORE PREDOMINANTLY THE INITIATING OR PROMOTING EFFECTS OF THE AGENT. SUCH PROTOCOLS SHOULD BE USED WHENEVER NECESSARY TO DIFFERENTIATE BETWEEN THESE TWO MECHANISMS OF ACTION. IN THE CAUCASIANS, THE "SPONTANEOUS" DEVELOPMENT OF THE PRIMARY HEPATOCELLULAR TUMORS IS RARE. THE MAJORITY OF THESE TUMORS ARE MALIGNANT AND RAPIDLY FATAL. ACCORDING TO SOME HUMAN PATHOLOGISTS, THE BENIGN VARIETY OF LIVER TUMORS IS RARE AND IT DOES NOT REPRESENT NECESSARILY A PREMALIGNANT STAGE IN TUMOR DEVELOPMENT. CARCINOMA OF THE LIVER MAY OCCUR IN INFANCY, ESPECIALLY IN MALES BEFORE THE AGE OF 2 YEARS. THIS SUGGESTS A GENETIC CAUSATION OR CARCINOGENIC EXPOSURE IN UTERO. ONE OF THE GEOGRAPHIC FACTORS WHICH SIGNIFICANTLY ENHANCES THE INCIDENCE OF HEPATOCELLULAR CARCINOMA IN HUMANS IS EXPOSURE TO AFLATOXIN B(1) WHICH IS APPARENTLY POTENTIATED BY CONCURRENT LIVER CIRRHOSIS. BECAUSE MANY MORE AGENTS HAVE BEEN FOUND TO BE HEPATOCARCINOGENIC IN MICE AND RATS THAN IN MEN, A QUESTION ARISES AS TO THE DIRECT RELEVANCE OF RODENT STUDIES TO HUMANS. A BALANCED ASSESSMENT OF THE CARCINOGENICITY OF THE AGENT COULD ONLY BE REACHED IN CONSIDERING BOTH THE PHARMACOKINETICS AND THE DEVELOPMENT OF MALIGNANT NEOPLASIA IN OTHER ORGANS. IN THE CASE OF POSITIVE CARCINOGENICITY ASSESSMENT, THE OUTCOME OF THE MUTAGENICITY BIOASSAYS CAN SUGGEST GENIC (GENOTOXIC) OR PARAGENIC (EPIGENETIC) MODE OF ACTION IN MAMMALIAN SYSTEMS.	1982
