    Full Text Available Abstract Background Adjustment Disorder is a condition strongly tied to acute and chronic stress. Despite clinical suggestion of a large prevalence in the general population and the high frequency of its diagnosis in the clinical settings, there has been relatively little research reported and, consequently, very few hints about its treatments. Methods the authors gathered old and current information on the epidemiology, clinical features, comorbidity, treatment and outcome of adjustment disorder by a systematic review of essays published on PUBMED. Results After a first glance at its historical definition and its definition in the DSM and ICD systems, the problem of distinguishing AD from other mood and anxiety disorders, the difficulty in the definition of stress and the implied concept of 'vulnerability' are considered. Comorbidity of AD with other conditions, and outcome of AD are then analyzed. This review also highlights recent data about trends in the use of antidepressant drugs, evidence on their efficacy and the use of psychotherapies. Conclusion AD is a very common diagnosis in clinical practice, but we still lack data about its rightful clinical entity. This may be caused by a difficulty in facing, with a purely descriptive methods, a "pathogenic label", based on a stressful event, for which a subjective impact has to be considered. We lack efficacy surveys concerning treatment. The use of psychotropic drugs such as antidepressants, in AD with anxious or depressed mood is not properly supported and should be avoided, while the usefulness of psychotherapies is more solidly supported by clinical evidence. To better determine the correct course of therapy, randomized-controlled trials, even for the combined use of drugs and psychotherapies, are needed vitally, especially for the resistant forms of AD.

    Full Text Available BACKGROUND: In order to facilitate public health response and to achieve early control of infectious disease epidemics, an adjustable epidemiologic information system (AEIS was established in the Taiwan public health network in February 2006. METHODOLOGY/PRINCIPAL FINDINGS: The performance of AEIS for the period 2006 through 2008 was evaluated based on a number of response times (RT and the public health impact. After implementation of the system, the apparent overall shortened RT was mainly due to the shortening of personnel response time (PRT and the time needed to draft a new questionnaire that incurred as personnel-system interface (PSI; PRT dropped from a fluctuating range of 9.8 ∼28.8 days in the first four months to <10 days in the following months and remained low till 2008 (0.88±1.52 days. The PSIs for newly emerged infectious diseases were 2.6 and 3.4 person-hours for H5N1 in 2007 and chikungunya in 2008, respectively, a much improvement from 1142.5 person-hours for SARS in 2003. The duration of each rubella epidemic cluster was evaluated as public health impact and showed a shortening trend (p = 0.019 that concurred with the shortening of PRT from 64.8±47.3 to 25.2±38.2 hours per cluster (p<0.0001. CONCLUSIONS/SIGNIFICANCE: The first evaluation of the novel instrument AEIS that had been used to assist Taiwan's multi-level government for infectious diseases control demonstrated that it was well integrated into the existing public health infrastructure. It provided flexible tools and computer algorithms with friendly interface for timely data collection, integration, and analysis; as a result, it shortened RTs, filled in gaps of personnel lacking sufficient experiences, created a more efficient flow of response, and identified asymptomatic/mild cases early to minimize further spreading. With further development, AEIS is anticipated to be useful in the application of other acute public health events needing immediate

    IMPORTANCE Current information on the prevalence and sociodemographic and clinical profiles of individuals in the general population with DSM-5 drug use disorder (DUD) is limited. Given the present societal and economic context in the United States and the new diagnostic system, up-to-date national information is needed from a single uniform data source. OBJECTIVE To present nationally representative findings on the prevalence, correlates, psychiatric comorbidity, disability, and treatment of DSM-5 DUD diagnoses overall and by severity level. DESIGN, SETTING, AND PARTICIPANTS In-person interviews were conducted with 36 309 adults in the 2012–2013 National Epidemiologic Survey on Alcohol and Related Conditions–III, a cross-sectional representative survey of the United States. The household response rate was 72%; person-level response rate, 84%; and overall response rate, 60.1%. Data were collected April 2012 through June 2013 and analyzed from February through March 2015. MAIN OUTCOMES AND MEASURES Twelve-month and lifetime DUD, based on amphetamine, cannabis, club drug, cocaine, hallucinogen, heroin, nonheroin opioid, sedative/tranquilizer, and/or solvent/inhalant use disorders. RESULTS Prevalences of 12-month and lifetime DUD were 3.9% and 9.9%, respectively. Drug use disorder was generally greater among men, white and Native American individuals, younger and previously or never married adults, those with lower education and income, and those residing in the West. Significant associations were found between 12-month and lifetime DUD and other substance use disorders. Significant associations were also found between any 12-month DUD and major depressive disorder (odds ratio [OR], 1.3; 95% CI, 1.09–1.64), dysthymia (OR, 1.5; 95% CI, 1.09–2.02), bipolar I (OR, 1.5; 95% CI, 1.06–2.05), posttraumatic stress disorder (OR, 1.6; 95% CI, 1.27–2.10), and antisocial (OR, 1.4; 95% CI, 1.11–1.75), borderline (OR, 1.8; 95% CI, 1.41–2.24), and schizotypal (OR, 1

    Full Text Available Abstract Background The purpose of the study was to identify the style of parental bonding and the personality characteristics that might increase the risk of hyperventilation and adjustment disorder. Methods A total of 917 males were recruited, 156 with adjustment disorder and hyperventilation syndrome (AD + HY, 273 with adjustment disorder without hyperventilation syndrome (AD–HY, and 488 healthy controls. All participants completed the Parental Bonding Instrument, Eysenck Personality Questionnaire, and Chinese Health Questionnaire. Results Analysis using structural equation models identified a pathway relationship in which parental bonding affected personality characteristics, personality characteristics affected mental health condition, and mental health condition affected the development of hyperventilation or adjustment disorder. Males with AD–HY perceived less paternal care, and those with AD + HY perceived more maternal protection than those with adjustment disorder and those in the control group. Participants with AD–HY were more neurotic and less extroverted than those with AD + HY. Both groups showed poorer mental health than the controls. Conclusions Although some patients with hyperventilation syndrome demonstrated symptoms of adjustment disorder, there were different predisposing factors between the two groups in terms of parental bonding and personality characteristics. This finding is important for the early intervention and prevention of hyperventilation and adjustment disorder.

    Full Text Available INTRODUCTION Autogenic training is a widespread technique used in psychotherapy. The British school of autogenic training cites a large list of diseases, health states, and life changes, in which autogenic training can be of help. We wanted to explore the application of autogenic training as a therapy for adjustment disorder in adolescents. The sample consisted of a homogeneous group of 31 individuals, with an average age of 17.3±0.2 years, who were diagnosed with adjustment disorder, F 43.2, in accordance with ICD 10 search criteria. OBJECTIVE The aim of our work was to figure out the influence of autogenic training on adjustment disorder, through biophysical and biochemical indicators, and to research the efficacy of autogenic training as a therapy for adjustment disorder in adolescents. METHOD We observed adjustment disorder indicators and their changes in three phases, using initial, final, and control values, which we measured immediately before the beginning, immediately after the completion, and six months after the completion, of the practical course in autogenic training. We measured systolic and diastolic arterial blood pressure, brachial pulse rates, cortisol levels in plasma, cholesterol levels in blood, as well as glucose concentrations. During that period, autogenic training was employed as the sole therapy. RESULTS The study confirmed our preliminary assumptions. The measurements we performed showed that arterial blood pressure, pulse rates, cholesterol and cortisol concentrations, after the application of autogenic training among adolescents suffering from adjustment disorder, were lower than the initial values. They remained lower even six months after the completion of the practical course in autogenic training. CONCLUSION We concluded that autogenic training significantly decreases the values of physiological indicators of adjustment disorder, diminishes the effects of stress in an individual, and eases the adaptation of

    Full Text Available Revised only twice in the 28 – year period from 1952 to 1980, the American Psychiatric Association`s Diagnostic and Statistical Manual of Mental Disorders (DSM has been amended two more times in half as many years, with the publication of DSM – III – R in 1987 and of DSM – IV in 1994. The DSM counterpart in use outside of North America, the International Classification of Diseases (ICD, also underwent modification during this time period. Requirements for the addictive disorders, or as termed here, psychoactive dependence or abuse disorders, were not immune to change for good reason and to a good end. Unlike other psychiatric disorders, for which ICD and DSM criteria often were the same, a schism existed between the DSM and ICD criteria for addictive disorders.ICD criteria were shaped by an influential article that introduced the construct of a dependence syndrome, but this conceptualization was not operationalized in the DSM system until the publication of DSM – IV. With this latest revision, criteria for substance dependence now closely matches those in the ICD – 10 system, establishing for the first time what may be considered a worldwide classification system for addictive disorders .

    Full Text Available The burden of psychiatric disorders in the developed countries has been identified by the screening questionnaires and standard clinical interviews at a high level, but the epidemiological studies of psychiatric disorders in our country are brief and their numbers are few. Planning for providing essential mental health services to the people requires us to be knowledgeable about the present status of psychiatric disorders in the society. The objective of this research was to carry out the epidemiological study of the psychiatric disorders in the individuals 18 years and above in urban and rural areas of Hamadan province. 664 individuals selected through randomized clustered and systematic sampling methods among the existing families of Hamadan province and the Schedule for Affective Disorders and Schizophrenia (SADS questionnaires completed by the clinical psychologist. The diagnosis of the disorders was based on DSM-IV classification criteria.The results of the study showed that the overall prevalence of psychiatric disorders in the province was 11.28% (17.2% in women , 5.8% in men. The anxiety and mood disorders with 5.87 and 2.71% respectively had the highest prevalence in the province. The prevalence of psychotic disorders in this study was 0.60% , neuro- cognitive disorders 1.35% and dissociative disorders 0.75%. In the group of mood disorders, major depression with 2.56% and in the group of anxiety disorders, phobia with 2.56% had the higher prevalence. This study showed that 8.13% of studied individuals suffered from at least one of the psychiatric disorders. The prevalence of psychiatric disorders in the province among the individuals in the age group of 66 years and above was 13.33%, individuals whose spouses had passed away 18.75%, urban residents of province 9.81%, illiterate individuals 12.80% and housewife individuals 12.31% was more than other individuals in the sample.

    Full Text Available In the new classification of American Psychiatric Association – DSM-5 – a category of autistic spectrum disorders (ASD was introduced, which replaced autistic disorder, Asperger syndrome, childhood disintegrative disorder and pervasive developmental disorder not otherwise specified. ASD are defined by two basic psychopathological dimensions: communication disturbances and stereotyped behaviors, and the diagnosis is complemented with the assessment of language development and intellectual level. In successive epidemiological studies conducted in 21 century the prevalence of ASD has been rising, and currently is estimated at 1% in general population. The lifetime psychiatric comorbidity is observed in majority of patients. The most common coexisting diagnoses comprise disorders of anxiety-affective spectrum, and in about 1/3 of patients attention deficit/ hyperactivity disorders could be diagnosed. Prodromal symptoms of ASD may emerge before 12 months of life, however reliability of diagnosis at such an early age is poor. Several screening instruments, based on the parental and/or healthcare professional assessments may be helpful in ASD detection. However, structured interviews and observation schedules remain the gold standard of diagnosis.

    Full Text Available Background: The WHO Global Burden of Disease study estimates that mental and addictive disorders are among the most burdensome in the world, and their burden will increase over the next decades. The mental and behavioral disorders account for about 12% of the global burden of disease. However, these estimates and projections are based largely on literature review rather than cross-national epidemiological surveys. In India, little is known about the extent, severity and unmet need of treatment mental disorders. Thus, there was a need to carry out rigorously implemented general population surveys that estimate the prevalence of mental disorders among urban population at Pune, Maharashtra. The study attempted to address unmet need and to form a basis for formulating the mental health need of the community. Objective: The study was undertaken to estimate the lifetime prevalence and 12 month prevalence of specific mental disorders in urban population, socio-demographic correlates of mental disorders and to assess the service utilization in individuals with mental disorders. Materials and Methods: The study was undertaken among adults aged 18 years and above living in house hold and in geographical area of Pune , Maharashtra. A minimum sample of 3000 completed interviews was planned using representative probabilities to population size (PPS sampling method which ensured equal probability for every eligible member. Data listing was obtained from Census Office from recent census of 2001 data. The face to face interviews were undertaken in homes using fully structured interview schedule of World Mental Health Survey Initiative duly revised Version of WHO- Composite International Diagnostic Interview (CIDI 3.0 by trained investigators. Clinical reappraisal was carried out using Schedules for Clinical Assessment in Neuropsychiatry (SCAN among ten percent of diagnosed cases selected randomly.

    This study examined the adult attachment styles, interpersonal distance from potential attachment figures and strangers, coping strategies, perceived social support, and stress-related self-variables among patients diagnosed with adjustment disorders (AJD). Seventy patients at an outpatient clinic and 61 matched controls completed a battery of standardized questionnaires. Univariate and multivariate statistical analyses were used to evaluate the parameters of interest. Using attachment theory (J. Bowlby, 1988) and the dynamic stress-vulnerability model of depressive disorder (G. W. Brown & T. O. Harris, 1989) as the analytical frameworks, the authors hypothesized that participants with AJD would: (a) display more insecure attachment styles, (b) be less tolerant of close interpersonal proximity, (c) use more emotion-oriented coping strategies, (d) display lower self-efficacy and self-esteem, and (e) perceive less social support from family, friends, and significant others. We further hypothesized that these variables would be predictive of depressive symptoms. All of the hypotheses were confirmed. The results suggest that the insecure fearful-avoidant attachment style is associated with severe depressive symptoms in patients with AJD. However, other psychosocial factors, such as low self-esteem and poor social support from friends, were more predictive of AJD symptoms. The findings warrant further studies on the risk and protective effects of these factors in the development of AJD and other stress-induced disorders.

    Challenges to epidemiological studies of eating and related body image disturbance disorders in males include, in addition to low base rates and the predominance of residual diagnostic categories, the female-centric nature of current classification schemes and the consequent lack of appropriate assessment instruments. In this narrative review, we summarise epidemiological data regarding the prevalence and correlates of eating disorders, related body image disturbance disorders, and eating disorder features in males. Attention is focused on disorders most likely to be observed among males, such as muscle dysmorphia and muscularity-oriented excessive exercise. It is argued that, given the multiple challenges involved in research of this kind, a focus on features is more likely to advance the field than a focus on diagnoses. In terms of correlates, we focus on impairment and help-seeking, since these issues are most relevant in informing public health burden, service provision, and related issues. We end with some thoughts about current gaps in the knowledge base and directions for future research that we consider to be most promising. PMID:27408719

Method: A keyword search was entered into Scopus (SciVerse, Elsevier to identify relevant articles published in English up until June 2013. Articles were assessed against a range of a priori inclusion and exclusion criteria. Results: A total of 149 full-text articles were found to be eligible for the review and included 86 articles with data on sociodemographic correlates, 57 on environmental correlates, and 13 on genetic correlates. Female sex, younger age, sexual and physical abuse, participation in esthetic or weight-oriented sports, and heritability were found to be most consistently associated with higher ED prevalence and incidence. Conversely, ethnicity, socioeconomic status, education, and urbanicity did not appear to have strong associations with ED epidemiology. Conclusion: More community-based research, with an equal representation of males, needs to be conducted to confirm the current findings and provide evidence for emerging factors that may be related to EDs.

    2014-06-01

    Introduction and objectives. Population-based research on mental disorders needs to keep pace with trends in general epidemiology. At present, this requirement is complicated by uncertainty within the parent discipline about its future development. The present study examines proposals for new directions in strategy and methods and considers their significance for psychiatric epidemiology. Method. Narrative review, cross-checked by search of English-language journals of epidemiology for new trends and developments reported in the years from 2000 onwards. Results. The proposals reviewed here are divided into three groups: 1. A new research paradigm of 'eco-epidemiology', which includes both individual risk factors and macro-environmental systems that mediate population levels of health and sickness. 2. Improved 'translation' of research findings - i.e. more rapid and effective implementation of epidemiological evidence into health policy and practice. 3. Adaptation of epidemiology to a globalised economy, with firmer regulation of funding and resources. Conclusions. Each of these proposals has implications for psychiatric epidemiology. Workers in this field, however, are still preoccupied by relatively specific problems of definition, measurement and classification, and so far the current debates in general epidemiology are scarcely reflected. The proposals outlined above call for: • a working model of eco-epidemiology as it relates to psychiatric disorders; • implementation strategies to encourage more active participation in epidemiological research by community health services and caregiver organisations; • international collaborative projects that offer practical benefits in training and service facilities for the countries taking part.

    Skin disorders, usually neglected and frequently underdiagnosed among diabetic patients, are common complications and encounter a broad spectrum of disorders in both type 1 and type 2 diabetes mellitus (DM)-e.g. cutaneous infection, dry skin, pruritus. Skin disorders are highly associated with increased risk of important outcomes, such as skin lesions, ulcerations and diabetic foot, which can lead to major complications and revolve around multifactorial factors besides hyperglycemia and advanced glycation end products. Although diabetic's skin disorders are consistent in the literature, there is limited data regarding early-stage skin disorders in DM patients. Disease control, early-stage treatment (e.g. skin hydration, orthotic devices) and awareness can reduce morbidity of DM patients. Thus, better understanding of the burden of skin disorders in DM patients may raise awareness on prevention and management. Therefore, the aim of this study is to perform a literature review to evaluate the main clinical characteristics and complications of skin disorders in diabetic's patients. Additionally, physiopathology early-stage skin disorders and dermocosmetic management were also reviewed. PMID:27583022

    Full Text Available To test the hypothesis of 'horizontal epidemiology', i.e. that psychosocial difficulties (PSDs, such as sleep disturbances, emotional instability and difficulties in personal interactions, and their environmental determinants are experienced in common across neurological and psychiatric disorders, together called brain disorders.A multi-method study involving systematic literature reviews, content analysis of patient-reported outcomes and outcome instruments, clinical input and a qualitative study was carried out to generate a pool of PSD and environmental determinants relevant for nine different brain disorders, namely epilepsy, migraine, multiple sclerosis, Parkinson's disease, stroke, dementia, depression, schizophrenia and substance dependency. Information from these sources was harmonized and compiled, and after feedback from external experts, a data collection protocol including PSD and determinants common across these nine disorders was developed. This protocol was implemented as an interview in a cross-sectional study including a convenience sample of persons with one of the nine brain disorders. PSDs endorsed by at least 25% of patients with a brain disorder were considered associated with the disorder. PSD were considered common across disorders if associated to 5 out of the 9 brain disorders and if among the 5 both neurological and psychiatric conditions were represented.The data collection protocol with 64 PSDs and 20 determinants was used to collect data from a convenience sample of 722 persons in four specialized health care facilities in Europe.57 of the PSDs and 16 of the determinants included in the protocol were found to be experienced across brain disorders.This is the first evidence that supports the hypothesis of horizontal epidemiology in brain disorders. This result challenges the brain disorder-specific or vertical approach in which clinical and epidemiological research about psychosocial difficulties experienced in daily

    Full Text Available Introduction. Adjustment disorders represent a frequent diagnostic entity especially among adolescents. They involve a wide spectrum of various emotional and behaviour problems. Objective. The aim was to investigate characteristics of diagnostic category known as adjustment disorders among hospital treated adolescents for the first time at the Clinical Department for Children and Adolescents of the Institute of Mental Health in Belgrade, during five consecutive years, as well as to investigate the outcome of the disorder in follow-up period. Methods. We conducted a retrospective investigation of the first time hospital treated adolescents from Belgrade with discharge diagnosis of adjustment disorders during 2000-2004. The follow up was conducted 5-10 years after a first discharge from the hospital. Results. During the investigated period 75 adolescents from Belgrade were hospitalized for the first time with diagnosis adjustment disorder. From the studied patients the main sample was formed that included 24 (32% males and 51 (68% females. After 5-10 years a follow-up of 52 patients was conducted (sample at follow-up which included 16 (30.77% males and 36 (69.23% females. Of the main sample, 70% of the patients were under follow-up. After the first hospitalization 58% of adolescents continued with further psychiatric treatment, either as rehospitalized or out-of-hospital patients. Conclusion. Our findings showed that 38% of adolescents under follow-up for 5-10 years after the first discharge from hospital with the diagnosis adjustment disorders had multiple hospitalizations. The outcome of the disorder among these patients was the worst, because three-quarters of the patients were rediagnosed in the follow-up period with a new psychiatric disorder, often from psychotic spectrum.

  20. Epidemiological and clinical characterization following a first psychotic episode in major depressive disorder: Comparisons with Schizophrenia and Bipolar I Disorder in the Cavan-Monaghan First Episode Psychosis Study (CAMFEPS).

    While recent research on psychotic illness has focussed on the nosological, clinical, and biological relationships between schizophrenia and bipolar disorder, little attention has been directed to the most common other psychotic diagnosis, major depressive disorder with psychotic features (MDDP). As this diagnostic category captures the confluence between dimensions of psychotic and affective psychopathology, it is of unappreciated heuristic potential to inform on the nature of psychotic illness. Therefore, the epidemiology and clinical characteristics of MDDP were compared with those of schizophrenia and bipolar disorder within the Cavan-Monaghan First Episode Psychosis Study (n = 370). Epidemiologically, the first psychotic episode of MDDP (n = 77) was uniformly distributed across the adult life span, while schizophrenia (n = 73) and bipolar disorder (n = 73) were primarily disorders of young adulthood; the incidence of MDDP, like bipolar disorder, did not differ between the sexes, while the incidence of schizophrenia was more common in males than in females. Clinically, MDDP was characterized by negative symptoms, executive dysfunction, neurological soft signs (NSS), premorbid intellectual function, premorbid adjustment, and quality of life similar to those for schizophrenia, while bipolar disorder was characterized by less prominent negative symptoms, executive dysfunction and NSS, and better quality of life. These findings suggest that what we currently categorize as MDDP may be more closely aligned with other psychotic diagnoses than has been considered previously. They indicate that differences in how psychosis is manifested vis-à-vis depression and mania may be quantitative rather than qualitative and occur within a dimensional space, rather than validating categorical distinctions.

    Full Text Available Abstract Background In the last years Italy is confronting with massive migratory movements from developing countries where hemoglobinopathies are widespread. This is causing a large diffusion and a changing spectrum in the epidemiology of hemoglobin disorders in Italy. Methods Investigations recently published in Italy on hemoglobinopathies among immigrants were revised in order to appreciate the impact of immigration from developing countries on epidemiology of these pathologies and to outline adequate guidelines of prevention. Results Although in Italy there is a limited number of investigations regarding the relation between immigration and hemoglobin disorders, published data show that in our Nation there is a changing and increasing spectrum of hemoglobinopathies linked to immigration. Conclusions Prospective and retrospective actions of public healthy preventive policy are requested, based upon information (health educational programs for immigrants and caregivers, screenings among immigrants (school screening, pre-marital, preconception and early pregnancy screening, newborn screening, counseling for foreign at-risk couples and healthy carriers.

    Full Text Available Abstract Background Multiple studies have demonstrated that rates of smoking and nicotine dependence are increased in individuals with anxiety disorders. However, significant variability exists in the epidemiological literature exploring this relationship, including study design (cross-sectional versus prospective, the population assessed (random sample versus clinical population and diagnostic instrument utilized. Methods We undertook a systematic review of population-based observational studies that utilized recognized structured clinical diagnostic criteria (Diagnostic and Statistical Manual of Mental Disorders (DSM or International Classification of Diseases (ICD for anxiety disorder diagnosis to investigate the relationship between cigarette smoking, nicotine dependence and anxiety disorders. Results In total, 47 studies met the predefined inclusion criteria, with 12 studies providing prospective information and 5 studies providing quasiprospective information. The available evidence suggests that some baseline anxiety disorders are a risk factor for initiation of smoking and nicotine dependence, although the evidence is heterogeneous and many studies did not control for the effect of comorbid substance use disorders. The identified evidence however appeared to more consistently support cigarette smoking and nicotine dependence as being a risk factor for development of some anxiety disorders (for example, panic disorder, generalized anxiety disorder, although these findings were not replicated in all studies. A number of inconsistencies in the literature were identified. Conclusions Although many studies have demonstrated increased rates of smoking and nicotine dependence in individuals with anxiety disorders, there is a limited and heterogeneous literature that has prospectively examined this relationship in population studies using validated diagnostic criteria. The most consistent evidence supports smoking and nicotine dependence as

    The authors sought to determine the 1-year-period prevalence and demographic characteristics of comorbid substance-related disorder (SRD) and dysthymia, as well as the demographic characteristics of SRD-dysthymia patients as compared with SRD-only patients. Patients being treated at two university medical centers and abstinent less than 2 years were followed prospectively for 6 months to establish the diagnosis of dysthymia. A total of 642 patients were assessed, of whom 39 had SRD-dysthymia and 308 had SRD only. Data collection instruments included a demographic questionnaire and assessment of DSM Axis I psychiatric diagnoses. The 1-year prevalence rate was lower than noted in previous studies where there were less stringent criteria for dysthymia. The rate of dysthymia among these SRD patients closely resembled that observed in a general population study. SRD-dysthymia patients and SRD-only patients did not differ on most demographic characteristics. SRD-dysthymia is not easily detected among recovering SRD patients because of the need for lengthy observation and the absence of special demographic characteristics.

  4. The epidemiology of autistic spectrum disorders: is the prevalence rising?

    2002-01-01

    For decades after Kanner's original paper on the subject was published in 1943, autism was generally considered to be a rare condition with a prevalence of around 2-4 per 10,000 children. Then, studies carried out in the late 1990s and the present century reported annual rises in incidence of autism in pre-school children, based on age of diagnosis, and increases in the age-specific prevalence rates in children. Prevalence rates of up to 60 per 10,000 for autism and even more for the whole autistic spectrum were reported. Reasons for these increases are discussed. They include changes in diagnostic criteria, development of the concept of the wide autistic spectrum, different methods used in studies, growing awareness and knowledge among parents and professional workers and the development of specialist services, as well as the possibility of a true increase in numbers. Various environmental causes for a genuine rise in incidence have been suggested, including the triple vaccine for measles, mumps and rubella (MMR]. Not one of the possible environmental causes, including MMR, has been confirmed by independent scientific investigation, whereas there is strong evidence that complex genetic factors play a major role in etiology. The evidence suggests that the majority, if not all, of the reported rise in incidence and prevalence is due to changes in diagnostic criteria and increasing awareness and recognition of autistic spectrum disorders. Whether there is also a genuine rise in incidence remains an open question.

    2001-01-01

    The aim of this study was to provide an update of the epidemiology of eating disorders (anorexia nervosa and bulimia nervosa), focusing on incidence and prevalence as well as other factors as age and sex. We made a review of the existing literature in the matter in the last decades. Likewise, we made an extent evaluation of the hypothetical pathogenic impact that exerts mass media (television and printed mass media) in these pathologies. We found an evident increase in incidence as well as prevalence of these disorders though it's far from being considered epidemic. We also found an undeniable influence of mass media in the genesis and maintenance of these disorders. However, mass media would exert a positive influence in the popularization of these entities to the general population that would result in a higher demand in general practice. PMID:11730579

    , esta epidemiología también se orienta hacia un dominio particular de determinantes (como el uso, abuso o dependencia hacia las drogas y cómo estas variables independientes afectan determinados procesos y enfermedades (como los accidentes, el homicidio, el suicidio, la cirrosis hepática, etc. Por último, la epidemiología de los trastornos mentales se ha caracterizado también por su interés en una serie de procesos que no parecen constituir síndromes propiamente dichos, pero que son a todas luces de interés sanitario, siendo el ejemplo más claro de esto el problema de la violencia. La epidemiología de los trastornos mentales se enfrenta a enormes retos en el nuevo milenio. Debe hacer frente a un panorama epidemiológico complejo y cambiante. Los aspectos más importantes de su desarrollo futuro se vinculan con los siguientes puntos: medición de los trastornos mentales y de los factores de riesgo, el diseño y métodos de muestreo más eficientes, la relación entre la investigación biológica, la genética, las disciplinas sociales y la epidemiología, y la interfase entre la epidemiología y la evaluación de los tratamientos y los servicios.Mental disorders, including substance abuse, are part of the Mexican epidemiologic scenario and will remain so during several decades. They may even become more prominent as causes of disease, disability, and death in our country. It is thus imperative to frame appropriate management strategies to curb these problems without delay. This paper aims at outlining epidemiology of mental diseases as a field of study, and to identify its limitations. Emphasis is made on common elements shared with other more traditional fields of epidemiology, as well as on the specific contributions made by this particular field to epidemiology and to psychiatry in general.

    Directory of Open Access Journals (Sweden)

    Evans David

    2012-10-01

    Full Text Available Abstract Background Directed acyclic graphs (DAGs are an effective means of presenting expert-knowledge assumptions when selecting adjustment variables in epidemiology, whereas the change-in-estimate procedure is a common statistics-based approach. As DAGs imply specific empirical relationships which can be explored by the change-in-estimate procedure, it should be possible to combine the two approaches. This paper proposes such an approach which aims to produce well-adjusted estimates for a given research question, based on plausible DAGs consistent with the data at hand, combining prior knowledge and standard regression methods. Methods Based on the relationships laid out in a DAG, researchers can predict how a collapsible estimator (e.g. risk ratio or risk difference for an effect of interest should change when adjusted on different variable sets. Implied and observed patterns can then be compared to detect inconsistencies and so guide adjustment-variable selection. Results The proposed approach involves i. drawing up a set of plausible background-knowledge DAGs; ii. starting with one of these DAGs as a working DAG, identifying a minimal variable set, S, sufficient to control for bias on the effect of interest; iii. estimating a collapsible estimator adjusted on S, then adjusted on S plus each variable not in S in turn (“add-one pattern” and then adjusted on the variables in S minus each of these variables in turn (“minus-one pattern”; iv. checking the observed add-one and minus-one patterns against the pattern implied by the working DAG and the other prior DAGs; v. reviewing the DAGs, if needed; and vi. presenting the initial and all final DAGs with estimates. Conclusion This approach to adjustment-variable selection combines background-knowledge and statistics-based approaches using methods already common in epidemiology and communicates assumptions and uncertainties in a standardized graphical format. It is probably best suited to

    1987-01-01

    This paper reviews the literature about the relationships between cultural change and psychopathology produced by Latin American researchers. With the analysis of 22 epidemiological studies, the author shows how culture has been traditionally viewed by social psychiatric research in Latin America as an independent variable associated with the prevalence of mental disorders. Two basic approaches have been analyzed: one of anthropological origin and the other based on sociological explanations. The hypotheses of cultural shock, stress of acculturation and cultural marginalization belong to the first approach, while the second one is manifested by the notions of urban stress, life change, social support and goal-striving stress. Methodological issues were brought about to evaluate the results on the association of cultural processes and psychopathology available in contemporary socio-psychiatric research in Latin America.

    Although mental health research in India has gained momentum in recent years and several epidemiological studies have begun to quantify psychiatric morbidities, there are few community-based epidemiological studies focusing specifically on prevalence and associated risk factors of emotional and behavioral disorders among children. A cross-sectional study was conducted in an urban slum of Karimnagar, Andhra Pradesh among 370 children selected by simple random sampling. Strength and difficulty questionnaire (SDQ) was used to estimate the prevalence of emotional and behavioral disorder. A semi-structured questionnaire was used to evaluate the social predictors of the condition, health-seeking behavior, and its impact on educational status of the children. Maternal depression was evaluated using patient health questionnaire (PHQ-9). Eighty-three (22.43%) children had an abnormal score on at least one domain of SDQ. Logistic regression analysis indicated that male gender (odds ration (OR) = 5.51), under-nutrition (OR = 2.74), low socioeconomic status (OR = 3.73), nuclear family (OR = 1.89), working status of the mother (OR = 2.71), younger age of the mother at the birth of the child (OR = 3.09), disciplinary method (OR = 2.31), financial problem at home (OR = 13.32), alcoholic father (OR = 11.65), conflicts in family (OR = 7.29), and depression among mother (OR = 3.95) were significant predictors. There was a significant impact on educational performance (p = 0.008) and parents had little awareness regarding the condition. The high frequency of emotional and behavioral problems, its impact on educational performance of the children, associated adverse social factors, poor knowledge, and treatment-seeking behavior of the parents in an urban slum warrants immediate attention. The interrelation of all these factors can be utilized to plan a continuum of comprehensive services that focus on prevention, early identification, and effective intervention strategies with

    This study examined the ability of executive functions (EF) to account for the relationship between Attention Deficit Hyperactivity Disorder (ADHD) status and social adjustment as indexed by parent and teacher report and by performance on a standardized observational "chat room" task. Children with the Combined subtype (ADHD-C; n = 23), the Primarily Inattentive Subtype (ADHD-I; n = 33), and non-ADHD controls (n = 36) participated. EF did not mediate the relationship between ADHD status and parent or teacher report of social adjustment. EF accounted for about 40-50% of the variance between ADHD status and the ability of children to detect subtle verbal cues as well as memory for the conversation in the chat room task, but did not mediate the relationship between ADHD and the number of prosocial, hostile, or on-topic statements that were made. Results are consistent with other recent reports, and suggest that the role of EF deficits in the production of social skill deficits in ADHD may not be as prominent as is typically assumed. The implications for the development of intervention programs designed to target core cognitive etiologic factors are discussed.

    Migraine is a common, often disabling disorder associated with a significant personal and societal burden. The presence of post-traumatic stress disorder (PTSD) may increase this disability substantially. Migraine and PTSD are both up to 3 times more common in women than in men. The divergence in prevalence rates of migraine and PTSD that occurs between the sexes after puberty suggests that gonadal hormones play an important role. In addition, the preponderance of PTSD in women may be related to their higher rates of interpersonal trauma, the most common cause of PTSD. However, recent data suggest that although the odds of PTSD are increased in both women and men with episodic migraine, this association is stronger in men than women. In this paper, we examine the epidemiology of PTSD and migraine, with an emphasis on the known sex differences. We then discuss the neurobiological changes associated with PTSD, the current hypotheses for the mechanisms relating PTSD and migraine, and the treatment implications of these findings.

    During the past quarter century biomedical scientists have begun to recognize the unique opportunities for studying disease etiology and mechanisms of pathogenesis in non-Western anthropological populations with focal, endemic diseases. The systematic search for etiological factors and mechanisms of pathogenesis of neurodegenerative disorders is perhaps nowhere better exemplified than in the western Pacific. During the past three decades, the opportunistic and multidisciplinary study of hyperendemic foci of amyotrophic lateral sclerosis and parkinsonism-dementia which occur in different cultures, in different ecological zones and among genetically divergent populations have served as natural models that have had a major impact on our thinking and enhanced our understanding of these and other neurodegenerative disorders such as Alzheimer disease and the process of early neuronal aging. Our cross-disciplinary approach to these intriguing neurobiological problems and the accumulated epidemiological, genetic, cellular and molecular evidence strongly implicates environmental factors in their causation, specifically the role of aluminum and its interaction with calcium in neuronal degeneration. As a direct consequence of our studies in these Pacific populations, we have undertaken the long-term development of experimental models of neuronal degeneration, in an attempt to understand the cellular and molecular mechanisms by which these toxicants affect the central nervous system. Our experimental studies have resulted in the establishment of an aluminum-induced chronic myelopathy in rabbits and the development of neurofilamentous lesions after low-dose aluminum administration in cell culture.

  20. Advances in epidemiological study of post-traumatic stress disorders in postwar civilian survivors

    Full Text Available Post-traumatic stress disorder (PTSD is a feeling of persecution arising from the exposure to a life-threatening event. PTSD shows three kinds of characteristic symptoms including intrusive, avoidance, and arousal syndromes. Numerous literatures had been published on the study of the PTSD epidemiology. However, research results varied due to different research subjects and evaluation methods used. A big difference exists between the studies on refugees, migrating population, and community population, because these studies are affected by different definitions of war trauma, difference in choice of samples, and application of psychological intervention. Therefore, no exact conclusions have been established on the accurate incidence of PTSD in civilians after having endured war trauma or mental torture. Currently, studies on PSTD are still inadequate. The first reason for this inadequacy is the difference existing between previous study methods. In addition, differences also exist in the statistical results between different research groups; the present study objects are all non-western ethnics or some specific population, thus selective bias existing in samples adopted. Secondly, the majority of the studies had no a control group, thus the results lacking reliability and universality. The third reason is that more attention should be paid to the impact of nationality and cultural background on the study of postwar PTSD. In summary, a large amount of work should be done in the field of PSTD epidemiology in the future. Therefore, it is very important to look for simple tools for screening and measuring PTSD in Chinese population, and investigate the incidence of PTSD after all kinds of traumatic events and its distribution for effectively preventing and treating PTSD.

    Full Text Available Alcohol use is a global public health problem, including as a risk factor for HIV infection, but few data are available on the epidemiology of alcohol use and alcohol use disorders (AUD among young people in sub-Saharan Africa.We conducted a cross-sectional survey among 4 groups of young people aged 15-24 years old (secondary school students, college/university students, employees of local industries and casual labourers in two regions (Kilimanjaro and Mwanza of northern Tanzania. Using a multistage stratified random sampling strategy, we collected information on demographics, alcohol use, and behavioural factors. We screened severity of alcohol use using the Alcohol Use Disorder Identification Test (AUDIT and estimated the quantity and frequency of alcohol consumption using the timeline-follow-back-calendar (TLFB method.A total of 1954 young people were surveyed. The prevalence of reported alcohol use was higher among males (47-70% ever users and 20-45% current users than females (24-54% ever users and 12-47% current users. Prevalence of use was substantially higher in Kilimanjaro than Mwanza region. In both regions, participants reported high exposure to alcohol advertisements, and wide alcohol availability. College students reported the highest prevalence of current alcohol use (45% among males; 26% among females and of heavy episodic drinking (71% among males; 27% among females followed by casual labourers. Males were more likely to have AUD (an AUDIT score ≥8 than females, with 11-28% of males screening positive for AUD. Alcohol use was associated with male gender, being in a relationship, greater disposable income, non-Muslim religion and a higher number of sexual partners.Alcohol use is a significant problem among young people in northern Tanzania. There is an urgent need to develop, pilot and deliver interventions to help young people delay initiation and reduce levels of harmful drinking, particularly among college students and casual

    Full Text Available Background: Epidemiological information paucity exists on musculoskeletal disorders (MSD among secondary school students in Nigeria. We aimed to determine the prevalence, pattern, and treatment seeking behaviors (TSB of MSD in Southwest, Nigeria. Materials and Methods: A school-based cross-sectional study was conducted in four randomly selected secondary schools in Ile-Ife in 2007. All the students were screened for MSD using an interviewer-administered questionnaire and physical examination, which involved the use of a scoliometer and a goniometer. Affected children were recommended for follow-up treatment and a plain radiography taken. Results: A total of 133 students had 204 MSD representing a 3.0% prevalence among the 4,441students screened. Eighty-one (60.9% students had congenital disorders and 52 (39.1% were acquired. The lower limbs (93.1% were most commonly affected and 87 (65.4% students presented with a knee deformity. Other abnormalities were limb length discrepancy 6.8%, scoliosis 4.4%, Pes planus 3.9%, and poliomyelitis 2.9%. A total of 100 students (75.2% had no form of treatment, 18.8% receive treatment in the hospital, 3.7% received treatment in a traditional healing home and 2.3% received treatment in a church. Age, family, and school type were significant factors ( P < 0.05 in health-seeking behavior. The factors affecting treatment outcome were the place of treatment, hospital specific treatment, and reasons for stopping treatment. Conclusion: Treatable cases constitute a large proportion of MSD among secondary school students, but TSB was generally poor. Parental socio-economic and health services factors were related to the health-seeking behavior. Strengthening of school health services and improved linkage with orthopedic services, community education on MSD, and education of all cadres of health professionals are recommended.

    Full Text Available The aim of this review is to describe the main theoretical findings and research conclusions about obsessive-compulsive disorder (OCD in the perinatal period. On one hand, epidemiological studies show that the risk of OCD onset and/or exacerbation could increase in this period, particularly in the puerperium. Phenomenologically, in this stage aggressive and contamination obsessions are very common and are related to the fetus or newborn. On the other hand, regarding OCD pathogenesis in this period, there is indirect evidence to suggest the participation of neuroendocrine (e.g. female gonadal steroids and oxytocin and cognitive behavioural variables (e.g. hyper-responsibility, threat overestimation, and mental control. In terms of research, more empirical studies are needed to contrast these specific vulnerability factors. Moreover, no empirically validated psychotherapeutic treatments (controlled trials adapted to this OCD sub-group were found, although some studies highlight the role of cognitive behavioural therapy (CBT as an effective intervention in the context of selective primary prevention.

    The current study investigates race-ethnic differences in rates of panic disorder, panic attacks and certain panic attack symptoms by jointly combining three major national epidemiological databases. The compared groups were White, African American, Latino and Asian. The White group had significantly higher rates of panic disorder, and of many panic symptoms, including palpitations, as compared to the African American, Asian and Latino groups. Several expected race-ethnic differences were not found. An explanation for these findings are adduced, and suggestions are given for future studies so that possible ethnic-racial differences in panic disorder, panic attacks and panic attack symptoms can be investigated in a more rigorous manner.

    Full Text Available Summary Objective: This study aims to describe the profile of medical schools that introduced courses on Geriatrics and Elderly Health or Aging in their curriculum, and compare such information with the age distribution and health epidemiological data of the Brazilian population, using data until the year of 2013. Methods: 180 universities offering medical undergraduate courses and registered with the Ministry of Education and Culture of Brazil (MEC were found, as seen on the MEC website (www.emec.mec.gov.br in February 2013. Based on the list of institutions, the authors created a database. Results: Brazil's Southeast region is the one presenting most of the courses, both offered as core or elective subjects, in the area of Geriatrics. The Midwest region had the least offer of Geriatrics and Elderly Health and Care courses. The Southeast region presents the greater absolute number of institutions with elective subjects, followed by the South and Northeast regions, each with a single institution. The Southeast region was at the same time the one that presented the biggest absolute number of institutions offering core subjects in the area of Geriatrics, being followed by the Northeast, South, North, and Midwest regions. Conclusion: By analyzing the availability of courses that emphasize aging and Geriatrics in brazilian medical schools, the present study reveals that specialized training should be encouraged with respect to the specificities of health care given to the elderly population, which has a higher frequency of chronic and degenerative diseases.

    2010-08-01

    Full Text Available Abstract Background Irritable bowel syndrome (IBS is commonly regarded as a functional disorder, and is hypothesized to be associated with anxiety and depression. This evidence mainly rests on population-based studies utilising self-report screening instruments for psychopathology. Other studies applying structured clinical interviews are generally based on small clinical samples, which are vulnerable to biases. The extant evidence base for an association between IBS and psychopathology is hence not conclusive. The aim of this study was therefore to re-examine the hypothesis using population-based data and psychiatric morbidity established with a structured clinical interview. Methods Data were derived from a population-based epidemiological study (n = 1077. Anxiety and mood disorders were established using the Structured Clinical Interview for DSM-IV-TR (SCID-I/NP and the General Health Questionnaire (GHQ-12. Current and lifetime IBS was self-reported. Hypertension and diabetes were employed as comparison groups as they are expected to be unrelated to mental health. Results Current IBS (n = 69, 6.4% was associated with an increased likelihood of current mood and/or anxiety disorders (OR = 2.62, 95%CI 1.49 - 4.60. Half the population reporting a lifetime IBS diagnosis also had a lifetime mood or anxiety disorder. Exploratory analyses demonstrated an increased prevalence of IBS across most common anxiety and mood disorders, the exception being bipolar disorder. The association with IBS and symptoms load (GHQ-12 followed a curved dose response pattern. In contrast, hypertension and diabetes were consistently unrelated to psychiatric morbidity. Conclusions IBS is significantly associated with anxiety and mood disorders. This study provides indicative evidence for IBS as a disorder with a psychosomatic aspect.

Apesar dos problemas para identificar e recrutar um número suficiente de pessoas com anorexia nervosa e os métodos variáveis de recrutamento de casos, os estudos sobre incidência e prevalência dos transtornos alimentares atingiram um consenso e em geral não corroboram uma incidência ascendente atual, exceto, possivelmente, por um pequeno aumento na anorexia nervosa em mulheres jovens. A aplicação de métodos epidemiológicos analíticos permitiu uma compreensão melhor dos fatores ambientais e genéticos, em comparação com os sociais e econômicos, quanto ao risco de desenvolvimento de transtornos alimentares, bem como ajudaram no refinamento da nosologia desses transtornos.

    Over the last decade a consistent increase in stress-related psychological consequences at the workplace, usually called 'mobbing', has been seen. It claimed physical, psychical and social distress as its victims, leading to an increased incidence of many illnesses, such as psychosomatic disorders (ache, high blood pressure, chronic fatigue and insomnia) and psychiatric disturbances (high level of anxiety, depression and suicidal attempts). It was recently demonstrated that mobbing is significantly widespread among healthcare workers, especially among female nurses. In this report, we illustrate the case of a nurse who, after a brilliant career, underwent mobbing at the workplace, showing depression, anxiety and sleep disorders that required hospitalisation and a substantial intervention.

  18. Occlusal adjustment using the bite plate-induced occlusal position as a reference position for temporomandibular disorders: a pilot study

    Science.gov (United States)

    2010-01-01

    Background Many researchers have not accepted the use of occlusal treatments for temporomandibular disorders (TMDs). However, a recent report described a discrepancy between the habitual occlusal position (HOP) and the bite plate-induced occlusal position (BPOP) and discussed the relation of this discrepancy to TMD. Therefore, the treatment outcome of evidence-based occlusal adjustments using the bite plate-induced occlusal position (BPOP) as a muscular reference position should be evaluated in patients with TMD. Methods The BPOP was defined as the position at which a patient voluntarily closed his or her mouth while sitting in an upright posture after wearing an anterior flat bite plate for 5 minutes and then removing the plate. Twenty-one patients with TMDs underwent occlusal adjustment using the BPOP. The occlusal adjustments were continued until bilateral occlusal contacts were obtained in the BPOP. The treatment outcomes were evaluated using the subjective dysfunction index (SDI) and the Helkimo Clinical Dysfunction Index (CDI) before and after the occlusal adjustments; the changes in these two indices between the first examination and a one-year follow-up examination were then analyzed. In addition, the difference between the HOP and the BPOP was three-dimensionally measured before and after the treatment. Results The percentage of symptom-free patients after treatment was 86% according to the SDI and 76% according to the CDI. The changes in the two indices after treatment were significant (p 0.1). Conclusion Although the results of the present study should be confirmed in other studies, a randomized clinical trial examining occlusal adjustments using the BPOP as a reference position appears to be warranted.

Results Analyses of covariance (ANCOVAs were conducted to examine differences between caregiver report of overprotection and parenting stress. Results revealed that caregivers of infants and toddlers exhibited more overprotective behaviors than caregivers of children in the other age groups. Further, caregivers of adolescents experienced significantly more parenting stress than caregivers of school-age children, and this effect was driven by personal distress and problematic parent-child interactions, rather than having a difficult child. Conclusions These results suggest that caregivers of children with disorders of sex development may have different psychosocial needs based upon their child's developmental stage and based upon the disorder-related challenges that are most salient at that developmental stage.

We set out to determine prevalence and socio-demographic factors associated with post-traumatic stress disorder (PTSD among IDPs. We also determined types of psycho-trauma experienced by the IDPs and their psychosocial adjustment.MethodsCross-sectional systematic random sampling was used to select 258 adults IDPs. We used Harvard trauma questionnaire to diagnose symptomatic PTSD, composite international diagnostic interview for diagnosis of depression, and communal trauma event inventory to determine exposure to psycho-trauma. We assessed social adjustment using social provision scale. Multiple logistic regression was used to determine independent predictors of PTSD. Results Of the 258 IDPs, 109 (42.2% had a diagnosis of PTSD, 204 (79.1% had poor living conditions, and only12 (4.7% had poor social provision. The most frequent psycho-traumas were destruction of personal property (96.1%, been evacuated from their town (96% and witnessing violence (88%. More than half (58% of IDPs had experienced 11 – 15 of the 19 traumatic events. Independent predictors of PTSD among respondents were, having a CIDI diagnosis of depression (Adjusted Odd Ratio [AOR]3.5, 95% CI 1.7 – 7.5; p= 0.001 and witnessing death of a family member ( 3.7, 1.2 – 11.5; p=0.0259.ConclusionWe concluded that exposure to psycho-trauma among IDPs in Kaduna led to post conflict PTSD. Death of a family member and co-morbid depression were independent predictors of PTSD among IDPs. Though their living condition was poor, the IDPs had good psychosocial adjustment. We recommended a structured psychosocial intervention among the IDP targeted at improving living condition and dealing with the psychological consequences of psycho-trauma.Key words Post traumatic stress disorder, psychosocial adjustment

    Full Text Available Background : Attention deficit hyperactivity disorder (ADHD persists in a majority of adolescents. It has been reported that ADHD patients have poor social functioning and risk for developing co-morbid psychiatric illnesses. Aims: To determine the retention of diagnosis of ADHD and to assess social adjustment, academic functioning and co-morbidities at follow-up. Design: Retrospective cohort study. Materials and Methods: ADHD patients of 5-14 years of age who came to the out-patient department from 2005 to 2008 were contacted telephonically. Fifty one patients could be contacted. Parents of patients were interviewed using Vanderbilt ADHD Diagnostic Parent Rating Scale for diagnosing ADHD and co-morbidities. Social Adjustment Inventory for Children and Adolescent was administered for assessing their academic and social functioning. Chi square test, Mann-Whitney Test, Kruskal-Wallis Test, and Pearson′s product moment correlations were used for statistical analysis. Results: At current assessment, out of 51 patients, 38 were still fulfilling diagnosis of ADHD. Of these, 21 were of inattention type, 3 were hyperactive, and 14 were of combined type. Social functioning and academic functioning were significantly better in those who currently did not fulfill the criteria for ADHD ( N=13. Twelve patients developed features of oppositional defiant disorder (ODD/conduct disorder (CD at follow-up. Conclusions: ADHD persists in the majority of adolescents. Decline with age is seen more in hyperactive/impulsive symptoms than inattentive symptoms. Several adolescents also develop features of ODD/CD in addition to poorer functioning. Continuation of treatment is crucial to prevent such consequences.

    2014-06-01

    The fifth edition of the Diagnostic and Statistic Manual for Mental Disorders (DSM-5) eliminates the committing illegal acts criterion and reduces the threshold for a diagnosis of gambling disorder to 4 of 9 criteria. This study compared the DSM-5 "4 of 9" classification system to the "5 of 10" DSM-IV system, as well as other permutations (i.e., just lowing the threshold to 4 criteria or just eliminating the illegal acts criterion) in 43,093 respondents to the National Epidemiological Survey of Alcohol and Related Conditions. Subgroups were analyzed to ascertain whether changes will impact differentially diagnoses based on gender, age, or race/ethnicity. In the full sample and each subpopulation, prevalence rates were higher when the DSM-5 classification system was employed relative to the DSM-IV system, but the hit rate between the two systems ranged from 99.80% to 99.96%. Across all gender, age, and racial/ethnic subgroups, specificity was greater than 99% when the DSM-5 system was employed relative to the DSM-IV system, and sensitivity was 100%. Results from this study suggest that eliminating the illegal acts criterion has little impact on diagnosis of gambling disorder, but lowering the threshold for diagnosis does increase the base rate in the general population and each subgroup, even though overall rates remain low and sensitivity and specificity are high.

    Full Text Available Abstract Background Self-directed and other violence as well as subsequent coercive interventions occur in a substantial proportion of patients with personality disorders during in-patient treatment. Different strategies may be required to reduce coercive interventions for patients of different diagnostic groups. Methods We specialised one of our acute admission wards in the treatment of personality disorders and adjustment disorders (ICD-10 F4 and F6. Patients are not transferred to other acute wards in case of suicidal or violent behaviour. Violent behaviour and coercive interventions such as seclusion or restraint were recorded in the same way as in the rest of the hospital. We recorded the percentage of subjects affected by diagnostic group and average length of an intervention in the year before and after the change in organisational structure. Results The total number of coercive interventions decreased by 85% both among patients with an F4 and those with an F6 primary diagnosis. Violent behaviours decreased by about 50%, the proportion of involuntary committed patients decreased by 70%. Conclusion The organisational change turned out to be highly effective without any additional cost of personnel or other resources.

    It is important to define subpopulations with mental health and psychosocial reactions in the medium-term following conflict to ensure that an appropriate array of services are provided to meet the diversity of needs. We conducted a latent class analysis (LCA) on epidemiological data drawn from an urban and rural sample of 1221 adults (581 men and 640 women, response 82%) in post-conflict Timor Leste 4 years after the cessation of violence. The prevalence of PTSD was 4.9%; severe distress 4.8%; anger attacks 38.3%; and paranoid-like symptoms 10.9%. The best fitting LCA yielded three classes comprising those with no or minimal symptoms (86%), a class with anger-paranoia (13%) and a comorbid mental disorder class (1.5%) characterized by PTSD (100%) and severe distress (98%). The comorbid mental disorder class had an over-representation of men, the unemployed, residents in the urban area and persons with the greatest exposure to human rights trauma, murder and health stress. The anger-paranoia class experienced moderate levels of trauma and had an over-representation of urban dwellers, women, and those with higher levels of education. The analysis assists in clarifying the populations with mental disorder and adverse psychosocial reactions in need of intervention in the medium-term following conflict.

    Restorative sleep is an important factor for well-being, performance and quality of life. The basic diagnostic procedure of a sleep disorder is to take a comprehensive sleep history. Sleep disorders can and must be distinguished from the physiological changes of sleep in the elderly. Insomnia (difficulty in sleeping), daytime sleepiness (hypersomnia), sleep-related breathing disorders (SRBD) and movement disorders during sleep are also common in the elderly. They must be detected because they are treatable and can dominate the clinical picture of geriatric syndromes. Nursing home residents and dementia patients are in particular need of attention as their sleep is often adversely affected by the living environment and the daily institutional routine.

There was no significant difference in prescribing of first-generation antipsychotic agents, although a reduction was found. There was a significant increase in utilization of second-generation antipsychotics and mood stabilizers.Conclusion: Our epidemiological findings are consistent with data reported in the literature regarding the high prevalence of major depression among the mood disorders, as well as the impact of familiality and comorbidity. Analysis of prescribing patterns for antidepressants, antipsychotics, and mood stabilizers in the treatment of mood disorders shows a shift from older to newer drugs, and wider use of mood stabilizers.Keywords: antidepressants, antipsychotics, mood stabilizers, prescribing patterns, mood disorders, treatment

    Carla Sabariego

    Full Text Available Persons with brain disorders experience significant psychosocial difficulties (PSD in daily life, e.g. problems with managing daily routine or emotional lability, and the level of the PSD depends on social, physical and political environments, and psychologic-personal determinants. Our objective is to determine a brief set of environmental and psychologic-personal factors that are shared determinants of PSD among persons with different brain disorders.Cross-sectional study, convenience sample of persons with either dementia, stroke, multiple sclerosis, epilepsy, migraine, depression, schizophrenia, substance dependence or Parkinson's disease. Random forest regression and classical linear regression were used in the analyses.722 subjects were interviewed in four European countries. The brief set of determinants encompasses presence of comorbidities, health status appraisal, stressful life events, personality changes, adaptation, self-esteem, self-worth, built environment, weather, and health problems in the family.The identified brief set of common determinants of PSD can be used to support the implementation of cross-cutting interventions, social actions and policy tools to lower PSD experienced by persons with brain disorders. This set complements a recently proposed reliable and valid direct metric of PSD for brain disorders called PARADISE24.

    It seems evident from a large number of studies that there is a positive relationship between exposure to whole body vibration (WBV) and the occurrence of low back pain. There are existing standards for evaluating the human exposure to WBV, which are based on other factors than the effect of musculoskeletal disorders. Several national and international standards also exist for evaluating human exposure to WBV. The exposure limit values or health guidance caution zones included in some of these standards are not or only to a limited extent based on systematic epidemiological investigations. It has not yet been possible to establish a clear exposure-response relationship. There are many confounding or contributing factors which influence the hazards to workers caused by exposure to WBV. Reliable methods for the detection and prevention of injury due to vibration exposure at work, alone or in combination with other risk factors, need to be implemented. The aim of this paper was to design a protocol and a questionnaire for conducting collaborative studies of WBV and musculoskeletal back disorders. The protocol will be tested in a pilot study before it will be used in multi-center studies.

    Insomnia is the predominant sleep concern in children with autistic spectrum disorder (ASD), and its nature is most likely multifactorial, with neurochemical (abnormalities in serotonergic transmission or melatonin levels), psychiatric (anxiety), and behavioral (poor sleep habits) etiological factors involved. Children with ASD experience sleep problems similar to those of typically developing children, although the prevalence is markedly higher, occurring in 44-83% of school-aged children with ASD. Caregivers usually report that insomnia is the most frequent sleep disorder, described as disorders of initiating and maintaining sleep, restless sleep, bedtime resistance, co-sleeping, alterations of sleep hygiene, and early awakenings in the morning. Many actigraphic studies have added information on sleep disorders, confirming the questionnaire findings in the majority of cases. There are relatively few polysomnographic data for ASD, compared with questionnaire studies, and most of these studies reported a reduction in total sleep time and more undifferentiated sleep in the youngest patients. These findings were associated with several sleep microstructure alterations during rapid eye movement (REM) sleep, and with non-REM (NREM) sleep microstructure changes that appeared to be related to cognitive impairment rather than to the autistic core. Moreover, few data about other less frequent sleep disorders, such as periodic limb movements disorder and obstructive sleep apnea syndrome, bruxism, and the influence of epilepsy and EEG abnormalities, are available. Both pharmacologic and behavioral interventions have been suggested for the treatment of sleep problems in autistic children. The most common types of behavioral interventions are complete extinction (removing reinforcement to reduce a behavior) and various forms of graduated extinction. Melatonin has shown promising results in the treatment of insomnia in children with ASD. Although controlled studies are limited

    The present study aims to describe a case of work injury and occupational disease which is unique for the type of disease diagnosed, conditions of onset and mode of management by INAIL (Italian National Institute of Insurance for Injuries at Work and Occupational Diseases). A worker, after a verbal animated dispute with some collegues and superiors, had an acute psychiatric agitation attack and went to the nearest emergency room, where he was subjected to clinical exams. No neuropsychiatric alteration was found, but the physicians diagnosed an anxiety crisis reactive to the work environment. Consequently, the medical certificate for work injury was edited and sent to INAIL. The worker has been off work for 110 days because of a anxious and depressive syndrome, due to the verbal conflict. In a later assessment, INAIL recognized only the first 30 days of the employee's time off as injury at work, while judging the following period off work as related to affectivity disturbance due to common disease, not related to work environment. The following year, "anxious-depressive syndrome" is worsened and attributed by the same worker to the recurrence of acts of persecution and discrimination against him at work. For this reason he applied for recognition of occupational disease diagnosed as "Chronic Adjustment Disorder with prolonged depressive reaction and somatic anxiety, which developed into a protracted conflict marked the employment situation". INAIL rejected that request, but in the same year the employee has submitted the complaint for "mobbing". Even this request was rejected. Literature shows many examples of traumatic events during working activities which cause psychiatric disturbances. These events include industrial disasters, explosions, transport and mining accidents, accidents in psychiatric units with high risks of assaults, armed conflicts, war, assault and sexual assault, natural disasters.

    The global population is currently undergoing an upward shift in its age structure due to decreasing fertility rates and increasing life expectancy. As a result, clinicians worldwide will be required to manage an increasing number of spinal disorders specific to the elderly and the aging of the spine. Elderly individuals pose unique challenges to health care systems and to spinal physicians as these patients typically have an increased number of medical comorbidities, reduced bone density mass, more severe spinal degeneration and a greater propensity to falls. In anticipation of the aging of the population, we undertook this project to heighten physicians' awareness of age-related spinal disorders, including geriatric odontoid fractures, central cord syndrome, osteoporotic compression fractures, degenerative cervical myelopathy, lumbar spinal stenosis and degenerative spinal deformity. This introductory article provides an overview of the changing demographics of the global population; discusses the age-related alterations that may occur to the spine; and summarizes the purpose and contents of this focus issue.

  4. Epidemiological study on periodontal diseases and some other dental disorders in dogs

    International Nuclear Information System (INIS)

    The prevalence of dental disorders in dogs was studied by applying index systems for human with some modifications. A total of 251 mongrel dogs including 143 stray dogs kept in the Animal Protection Offices in Tokyo and Hokkaido and 108 pet dogs visiting veterinary clinicians in Chiba Prefecture and Hokkaido were used. Periodontitis was prevalent among these dogs regardless of their sources and its incidence was increased with age. The lesion was more severe and more frequent in the premolar and molar regions than in the maxillary and mandibular incisor regions. Missing of teeth was observed at a high and increasing incidence with age. The tooth most commonly lost was the first premolar, followed by the other premolars and molars, where severe periodontitis was frequently found. Calculus was seen on many teeth, and aging agravated its prevalence and severity. Dental caries was observed in stray dogs, but neither to a serious degree nor at a significant level. These findings emphasize the necessity of dental hygiene, proper dental care and continuous periodical survey for dogs

    Full Text Available Abstract Data from surveys of large samples showed the lifetime prevalence rates of bipolar disorder around 1.5%. A main question is whether the low prevalence rates of bipolar disorders are not an artefact of the over-diagnosis of depression and under-diagnosis of bipolar-II. Analysis of the clinician's logical inferential diagnostic process, confirms that the patient does not represent the sole source of useful information because many patients do not experience hypomania as distress but rather as recovery from depression or as a period during which they felt truly well. Epidemiological data are derived from interviews carried out by lay staff which only reflect the patient's point of view. The clinical monitoring study carried out alongside the ESEMED project found for the diagnosis of mood disorders, a Kappa agreement (versus clinical interview which ranged from 0.23 in Spain to 0.49 in France. If we consider exactly what a Kappa of 0.4 implies for a disorder with an "identified" prevalence rate of 2%, we discover that the prevalence rate may have been under-diagnosed approximately 1.5-fold, so 67% of cases may not have been identified and 50% of the identified cases may be false positives. It is legitimate to surmise that the prevalence reported by recent (extremely costly epidemiological surveys may be doubtful. Which direction should epidemiology take in dealing with the serious matter of bipolar disorders? Recently, some community surveys were carried out in the USA using the Mood Disorder Questionnaire. In the ensuing debate, one side claimed that the instrument was scarcely accurate when used in the general population, gave rise to numerous false positives and that the high prevalence reported was therefore a mere artefact. The other side defended the results reported by the research studies, on the basis that "positive" cases were homogeneous with regard to the high level of subjective distress, low social functioning and employment

    Full Text Available Autism is one of disorders from the autism spectrum, besides Asperger syndrome, atypical autism and pervasive developmental disorder not otherwise specified. They are classified as mental disorders as being manifested by a wide range of cognitive, emotional and neurobehavioural abnormalities. Key categorical characteristics of the disorder are clear impairments of the development of the child’s socialisation, understanding and production of verbal and non-verbal communication and restricted and repetitive patterns of behaviour. Demarcation boundaries are not clear, neither within the very group of the disorders from the autistic spectrum, nor with respect to the autistic behavioural features in the general population. For this reason, the term spectrum points out the significance of the dimensional assessment of autistic disorders, which will most likely be the basis of the new diagnostic classification of the disorders belonging to the current group of pervasive developmental disorders in the new DSM-V classification. The understanding, as well as the prevalence of the autistic spectrum disorders has changed drastically in the last four decades. From the previous 4 per 10,000 people, today’s prevalence estimates range from 0.6 to around 1%, and the increase of prevalence cannot be explained solely by better recognition on the part of experts and parents or by wider diagnostic criteria. The general conclusion is that the autistic spectrum disorders are no longer rare conditions and that the approach aimed at acknowledging the warning that this is an urgent public health problem is completely justified.

    Despite differences in their mechanisms and outcomes, little is known about whether postsurgical changes in eating behaviours also differ by bariatric procedure. Following a systematic search, 23 studies on changes in binge eating disorder (BED) and related behaviours, bulimia nervosa and related behaviours, night eating syndrome, grazing and emotional eating after Roux-en-Y gastric bypass (RYGB), adjustable gastric banding (AGB) and vertical sleeve gastrectomy (VSG) were reviewed. Significant methodological problems and a dearth of literature regarding many behaviours and VSG were seen. Regarding BED and related behaviours, although later re-increases were noted, short to medium-term reductions after RYGB were common, and reported changes after AGB were inconsistent. Short to medium-term reductions in emotional eating, and from a few studies, short to long-term reductions in bulimic symptoms, were reported after RYGB. Reoccurrences and new occurrences of problem and disordered eating, especially BED and binge episodes, were apparent after RYGB and AGB. Further conclusions and comparisons could not be made because of limited or low-quality evidence. Long-term comparison studies of changes to problematic and disordered eating in RYGB, AGB and VSG patients are needed. It is currently unclear whether any bariatric procedure leads to long-term improvement of any problematic or disordered eating behaviours. PMID:27296934

    This study assessed the role of some common mental health conditions as mediators in the pathway between suffering life events and using mental health services. The participants were from the Baltimore Epidemiologic Catchment Area cohort, interviewed in 1993 to 1996 and 2004 to 2005. Longitudinal data analysis was used to identify models with significant mediation. Only alcohol abuse/dependence disorder was a significant mediator in the pathway between suffering a life-threatening illness and using mental health services in a general medical setup. Female gender, being more than 65 years old, prior use of services and availability of health insurance were some of the factors that significantly predicted service use in that model. Some of other factors like social networks and social support, attitudes towards services, and stigma, may play a role in determining service use. Future research should investigate the role of such factors as mediators for mental health service use. PMID:20215995

    Full Text Available Introducción: En la actualidad, existe la mayor ocurrencia de enfermedades de origen biopsicosocial, en especial los trastornos alimentarios, que involucran diferentes sistemas del cuerpo y los aspectos inherentes a la persona y sus relaciones sociales. Objetivo: Abordar temas actuales y relevantes acerca de la prevalencia, la incidencia y los factores de riesgo de anorexia y bulimia nerviosa en la adolescencia. Métodos: Búsqueda en las bases de datos MEDLINE, SciELO y LILACS de estudios publicados sobre la epidemiología y los factores de riesgo de trastornos alimentarios en la adolescencia. Resultados: La mayor incidencia de la anorexia y bulimia nerviosa se presenta entre las niñas en la fase media y final de la adolescencia. Entre los factores que aumentan el riesgo para la aparición de los trastornos alimentarios en la adolescencia se encuentran: la genética, los cambios corporales en la pubertad, la vulnerabilidad de los adolescentes a los ideales de delgadez, la presión social por ser delgada, la insatisfacción con la imagen corporal, la dieta restrictiva, la depresión y la baja autoestima. Sin embargo, se sugiere que en las diferentes culturas los trastornos del comportamiento alimentario pueden venir de una serie de condiciones no relacionadas con las conductas compensatorias o con el peso, pero con la forma del cuerpo o parte de lo mismo. Conclusiones: Varios factores determinan la aparición de la anorexia y la bulimia en la adolescencia, sin embargo, no hay consenso en cómo interactúan estos factores en este complejo proceso, lo que indica la necesidad de más investigaciones.Introduction: Currently, there is a higher occurrence of biopsychosocial diseases, especially eating disorders, involving different body systems and aspects related to the individual and their social relations.

    To find the prevalence of 8 mental disorders and study knowledge, attitude, practice (KAP) upon mental health among people in Bangkok Metropolis a cross sectional, descriptive community survey was conducted. Two thousand, nine hundred and forty eight samples aged 15-60 years were selected by a multistage simple random sampling technique. Data collection was made by qualified interviewers who had experience in mental health care and had been trained to use the questionaires. The questionaires had been modified from DSM-IV and CIDI that had been tested for good validity and reliability. The survey methodology was divided into 2 stages, screening and diagnosis. The results showed that the life time prevalence of mental disorders were; schizophrenia (1.3%), mood disorders; manic episode (9.3%), major depressive episode (19.9%), dysthymia (1%), anxiety disorders (10.2%), mental retardation (1.8%), epilepsy (1.3%), suicidal idea (7.1%), drug and substances use disorders (11.2%), and alcohol use disorders (18.4%). Knowledge score was good, attitude was fairly good, practice was still weak in promotion and prevention aspects. As such, this study was used as a pattern to conduct a national survey in 14 provinces all over Thailand and the results are being summarized. The information is similar to the Global Burden of Diseases. We produced a national training program on "Detection and Management of Depression" for Primary Care Physicians that was, a 2 days' workshop. Other national programs promoting prevention and control have also been set up. PMID:11529323

    儿童孤独症是一类起病于3岁以前的神经系统发育障碍,属于广泛性发育障碍的一个亚型。精神障碍诊断与统计手册第五版(DSM-Ⅴ)已将其归类为孤独症谱系障碍(ASD)。1980年以前,孤独症被认为是一种罕见性疾病,而近些年有关孤独症及ASD的流行病学研究表明,其发病率日趋上升,2014年美国疾病控制与预防中心对11个州8岁儿童的监测数据发现,ASD患病率高达14.7/1000,即相当于68例儿童中即有1例为ASD患儿,本文综述了目前ASD流行病学研究现状,并分析患儿性别、种族、智力、地域间的差异,为ASD的早期发现与早期干预提供理论依据。%Autism is a neurodevelopmental disorder with onset before the age of 3 years old, and is a subtype of pervasive developmental disorder. It has been classified as autism spectrum disorder in DSM-Ⅴ. Before 1980, autism was considered as a rare disease, in recent years, the epidemiological studies show that the incidence of autism tends to rise. In 2014, from the site of the Centers for Disease Control and Prevention of America, the overall prevalence of ASD among the ADDM sites was 14.7 per 1 000 children, which is equivalent to 68 cases of children that have one case for children with autism, we reviewed the study of epidemiology of ASD and analyzed the differences of gender, race, intelligence and regions of them, so as to provide a theoretical basis for its early detection and intervention.

    Full Text Available Siblings of children with autism are at a greater risk of experiencing behavioral and social problems. Previous researches had focused on environmental variables such as family history of autism spectrum disorders (ASDs, behavior problems in the child with an ASD, parental mental health problems, stressful life events and "broader autism phenotype" (BAP, while variables like parenting style and family function that are shown to influence children's behavioral and psychosocial adjustment are overlooked. The aim of the present study was to reveal how parenting style and family function as well as BAP effect psychological adjustment of siblings of children with autism.The Participants included 65 parents who had one child with an Autism Spectrum Disorder and one typically developing child. Of the children with ASDs, 40 were boys and 25 were girls; and they were diagnosed with ASDs by a psychiatrist based on DSM-IV-TR criteria and Autism Diagnostic Interview-Revised (ADI-R. The Persian versions of the six scales were used to collect data from the families. Pearson's correlation test and regression analysis were used to determine which variables were related to the psychological adjustment of sibling of children with ASDs and which variables predicted it better.Significant relationships were found between Strengths and Difficulties Questionnaire (SDQ total difficulties, prosocial behaviors and ASDs symptoms severity, parenting styles and some aspects of family function. In addition, siblings who had more BAP characteristics had more behavior problems and less prosocial behavior. Behavioral problems increased and prosocial behavior decreased with permissive parenting style. Besides, both of authoritarian and authoritative parenting styles led to a decrease in behavioral problems and an increase in prosocial behaviors. Our findings revealed that some aspects of family function (affective responsiveness, roles, problem solving and behavior control were

    The purpose of this study was to evaluate the psychometric properties of DSM-IV symptom criteria for assessing personality disorders (PDs) in a national population and to compare variations in proposed symptom coding for social and/or occupational dysfunction. Data were obtained from a total sample of 34,653 respondents from Waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). For each personality disorder, confirmatory factor analysis (CFA) established a 1-factor latent factor structure for the respective symptom criteria. A 2-parameter item response theory (IRT) model was applied to the symptom criteria for each PD to assess the probabilities of symptom item endorsements across different values of the underlying trait (latent factor). Findings were compared with a separate IRT model using an alternative coding of symptom criteria that requires distress/impairment to be related to each criterion. The CFAs yielded a good fit for a single underlying latent dimension for each PD. Findings from the IRT indicated that DSM-IV PD symptom criteria are clustered in the moderate to severe range of the underlying latent dimension for each PD and are peaked, indicating high measurement precision only within a narrow range of the underlying trait and lower measurement precision at lower and higher levels of severity. Compared with the NESARC symptom coding, the IRT results for the alternative symptom coding are shifted toward the more severe range of the latent trait but generally have lower measurement precision for each PD. The IRT findings provide support for a reliable assessment of each PD for both NESARC and alternative coding for distress/impairment. The use of symptom dysfunction for each criterion, however, raises a number of issues and implications for the DSM-5 revision currently proposed for Axis II disorders (American Psychiatric Association, 2010).

    Adjustment disorders (AjD) are among the most frequent mental disorders yet often remain untreated. The high prevalence, comparatively mild symptom impairment, and transient nature make AjD a promising target for low-threshold self-help interventions. Bibliotherapy represents a potential treatment for AjD problems. This study investigates the effectiveness of a cognitive behavioral self-help manual specifically directed at alleviating AjD symptoms in a homogenous sample of burglary victims. Participants with clinical or subclinical AjD symptoms following experience of burglary were randomized to an intervention group (n = 30) or waiting-list control group (n = 24). The new explicit stress response syndrome model for diagnosing AjD was applied. Participants received no therapist support and assessments took place at baseline, after the one-month intervention, and at three-month follow-up. Based on completer analyses, group by time interactions indicated that the intervention group showed more improvement in AjD symptoms of preoccupation and in post-traumatic stress symptoms. Post-intervention between-group effect sizes ranged from Cohen's d = .17 to .67 and the proportion of participants showing reliable change was consistently higher in the intervention group than in the control group. Engagement with the self-help manual was high: 87% of participants had worked through at least half the manual. This is the first published RCT of a bibliotherapeutic self-help intervention for AjD problems. The findings provide evidence that a low-threshold self-help intervention without therapist contact is a feasible and effective treatment for symptoms of AjD. PMID:27299909

    Several reports suggest children with autism spectrum disorder (ASD) are more likely to be seen for injury-related ED visits; however, no nationally representative study has examined this question. Using data from the 2008 Nationwide Emergency Department Sample, over a quarter of all visits among those with ASD were related to injury. In the multivariate analyses, the odds of an injury-related visit was 54 % greater among those with ASD compared to youth with intellectual disability (ID), but 48 % less compared to youth without ID or ASD. Compared to all other pediatric injury-visits in the US, visits among children with ASD were more likely to be due to self-inflicted injury and poisoning and were more likely to result in hospitalization (all p < 0.001).

  11. WHO - IPHECA: Epidemiological aspects

    International Nuclear Information System (INIS)

    In May 1991 the World Health Assembly endorsed the establishment of the International Programme on the Health Effects of the Chernobyl Accident (IPHECA) under the auspices of WHO. Five pilot projects have been carried out within IPHECA in the study territories of Belarus, Russian Federation and Ukraine in a period from 1991 to 1994. This pilot projects dealt with the detection and treatment of leukaemia and related diseases (Haematology Project), thyroid disorders (Thyroid project), brain damage during exposure 'in-utero' (Brain Damage 'in-Utero' project) and with the development of the Chernobyl registries (Epidemiological Registry Project). A fifth pilot project on oral health was performed only in Belarus. Epidemiological investigations have been an important component of all IPHECA pilot projects. Within 'Epidemiological Registry' Project such investigations have been the principal activity. But with respect to other IPHECA projects it was carried out in addition to main objectives relating to medical monitoring, early diagnosis and treatment of specific diseases included in project protocols. To support the epidemiological investigations within IPHECA, WHO supplied 41 computers in Belarus, Russian Federation and Ukraine and provided training for specialists from these countries in internationally recognized centres. The training programmes and host countries were as follows: standardization of epidemiological investigations (United Kingdom), radiation epidemiology (Russia), development of software (United Kingdom), principles of epidemiological investigations (The Czech Republic), cohort investigations (Japan)

  12. Relation between post-Chernobyl low level thyroid irradiation, stable iodine deficiency and thyroid disorders in Lithuania (epidemiological study: 1992-1996)

    International Nuclear Information System (INIS)

    The volatile radioiodine was detected in Lithuania in the very first day after the Chernobyl accident. Aim of the study was to perform the epidemiological investigation of thyroid disorders among Lithuanian inhabitants and to compare the data with thyroid radioiodine doses and stable iodine deficiency (urinary iodine excreation) results. Thyroid equivalent doses were estimated using the modified ICRP three-compartment cyclic model. These calculations applied Monte Carlo methods and consideration of regional iodine deficiency. The adult thyroid doses range up to about 50 mSv and the infant's and children's doses amounted to 200 mSv. High prevalence of thyroid abnormalities (up to 48%) are attributable to deleterious effect of ionising radiation as well as stable iodine deficiency for geological and socio-economical reasons. These data may be useful for estimating health effects that could develop in the future among Lithuanian inhabitants as a result of stable iodine deficiency and radioiodine exposure following the Chernobyl accident, especially amongst those who were infants at the time of accident.

    Full Text Available Abstract Background Detecting candidate markers in transcriptomic studies often encounters difficulties in complex diseases, particularly when overall signals are weak and sample size is small. Covariates including demographic, clinical and technical variables are often confounded with the underlying disease effects, which further hampers accurate biomarker detection. Our motivating example came from an analysis of five microarray studies in major depressive disorder (MDD, a heterogeneous psychiatric illness with mostly uncharacterized genetic mechanisms. Results We applied a random intercept model to account for confounding variables and case-control paired design. A variable selection scheme was developed to determine the effective confounders in each gene. Meta-analysis methods were used to integrate information from five studies and post hoc analyses enhanced biological interpretations. Simulations and application results showed that the adjustment for confounding variables and meta-analysis improved detection of biomarkers and associated pathways. Conclusions The proposed framework simultaneously considers correction for confounding variables, selection of effective confounders, random effects from paired design and integration by meta-analysis. The approach improved disease-related biomarker and pathway detection, which greatly enhanced understanding of MDD neurobiology. The statistical framework can be applied to similar experimental design encountered in other complex and heterogeneous diseases.

    Full Text Available Abstract Background The aim of this study was to assess the magnitude of the university population at high-risk of developing an eating disorder and the prevalence of unhealthy eating attitudes and behaviours amongst groups at risk; gender, school or academic year differences were also explored. Methods A cross-sectional study based on self-report was used to screen university students at high-risk for an eating disorder. The sample size was of 2551 university students enrolled in 13 schools between the ages of 18 and 26 years. The instruments included: a social-demographic questionnaire, the Eating Disorders Inventory (EDI, the Body Shape Questionnaire (BSQ, the Symptom Check List 90-R (SCL-90-R, and the Self-Esteem Scale (RSE. The sample design is a non-proportional stratified sample by academic year and school. The prevalence rate was estimated controlling academic year and school. Logistic regression analysis was used to investigate adjusted associations between gender, school and academic year. Results Female students presented unhealthy weight-control behaviours as dieting, laxatives use or self-induced vomiting to lose weight than males. A total of 6% of the females had a BMI of 17.5 or less or 2.5% had amenorrhea for 3 or more months. In contrast, a higher proportion of males (11.6% reported binge eating behaviour. The prevalence rate of students at high-risk for an eating disorder was 14.9% (11.6–18 for males and 20.8% (18.7–22.8 for females, according to an overall cut-off point on the EDI questionnaire. Prevalence rates presented statistically significant differences by gender (p Conclusion The prevalence of eating disorder risk in university students is high and is associated with unhealthy weight-control practices, similar results have been found in previous studies using cut-off points in questionnaires. These results may be taken into account to encourage early detection and a greater awareness for seeking treatment in order

    AbstractBackgroundAttention Deficit Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder characterised by the symptoms of inattention, impulsivity and hyperactivity. ADHD was once perceived as a condition of childhood only; however increasing evidence has highlighted the existence of ADHD in older adolescents and adults. Estimates for the prevalence of ADHD in adults range from 2.5–4%. Few data exist on the prescribing trends of the stimulants methylphenidate and dexamfetamine, and the non-stimulant atomoxetine in the UK. The aim of this study was to investigate the annual prevalence and incidence of pharmacologically treated ADHD in children, adolescents and adults in UK primary care.MethodsThe Health Improvement Network (THIN) database was used to identify all patients aged over 6 years with a diagnosis of ADHD\\/hyperkinetic disorder and a prescription for methylphenidate, dexamfetamine or atomoxetine from 2003–2008. Annual prevalence and incidence of pharmacologically treated ADHD were calculated by age category and sex.ResultsThe source population comprised 3,529,615 patients (48.9% male). A total of 118,929 prescriptions were recorded for the 4,530 patients in the pharmacologically treated ADHD cohort during the 6-year study.

    2013-01-01

    Full Text Available Abstract Background As the various systems in the body are inter-connected to form a single structural unit, a pathological condition in one area can also affect other areas. There are many known correlations between the visual and motor system. The importance of visual function, particularly the paracentral peripheral field of view, in motor coordination, ambulation and the maintenance of balance has been amply demonstrated. In line with current medical principles, which are moving towards a more holistic view of the human body, this study aims to investigate, in an interdisciplinary manner, the incidence of dental malocclusions together with posture and eye convergence disorders. Methods Six hundred and five children attending at the 3rd, 4th and 5th years of seven Genoa primary schools were examined. Each child underwent the following examinations: (i dental/occlusal; (ii orthoptic; and (iii postural. Occlusal data concerned the presence of cross-bite, midline deviation with a mandibular shift, bad habits and deep or open bite. Postural assessment involved frontal and lateral inspection, investigation during trunk flexion and ambulation, and note of any asymmetry in the lower limbs. The recorded orthoptic data included those pertaining to ocular dominance, a cover test, convergence and the Brock string test. Results A prevalence of cases with an unphysiological gait was found in patients with overjet (14.70% or overbite (14.87%, while the percentage of patients with normal occlusion that showed an unphysiological gait was 13.08%. Also, about 93.8%–94.2% of children showed normal legs without dysmetry, with no difference in respect to the type of occlusion. Subjects with an open bite or deep bite showed a slightly different distribution of right or left dominant eyes. Conclusion About 13% of children showed a pathological gait and, among them, vertical anomalies of occlusion (deep bite or open bite were prevalent with respect to the other

    Research is limited on the effects of regular substance use on mental health-related outcomes. We used a large nationally representative survey to examine current and future quality of life and risk of psychiatric disorders among past-year regular (weekly) users of alcohol, nicotine, and cannabis. Data on psychiatric disorders and quality of life from two waves (Wave 1 N = 43,093, Wave 2 N = 34,653) of the National Epidemiological Survey on Alcohol and Related Conditions (NESARC) were used to test study aims. In cross-sectional analyses, regular nicotine and cannabis use were associated with higher rates of psychiatric disorder, though regular alcohol use was associated with lower rates of disorders. Prospective analyses found that regular nicotine use predicted onset of anxiety, depressive, and bipolar disorders. Regular alcohol use predicted lower risk of these disorders. Regular cannabis use uniquely predicted the development of bipolar disorder, panic disorder with agoraphobia, and social phobia. Lastly, regular alcohol use predicted improvements in physical and mental health-related quality of life, whereas nicotine predicted deterioration in these outcomes. Regular cannabis use predicted declines in mental, but not physical health. These data add to the literature on the relations between substance use and mental and physical health and suggest increased risk of mental health problems among regular nicotine and cannabis users and better mental and physical health among regular alcohol users. Examination of mechanisms underlying these relationships is needed. PMID:26022838

    People with mental disorders, especially personality disorders, often face low acceptance at work. This is particularly problematic when returning to work after sick leave, because it impedes reintegration into the former workplace. This study explores colleagues' reactions towards a problematic worker dependent on the returning person's reintegration strategy: The returning person undertaking changes in their behaviour is compared with the person requesting adjustments of the workplace. In an experimental study, 188 employed persons read one of four vignettes that described a return-to-work-situation of a problematic co-worker. Across all vignettes, the co-worker was depicted as having previously caused problems in the work team. In the first vignette, the co-worker did not change anything (control condition) when she returned to work; in the second, she asked for workplace adjustments; in the third vignette she initiated efforts to change her own behaviour; and the fourth vignette combined both workplace adjustments and behavioural change. Study participants were asked for their reactions towards the problematic co-worker. Vignettes that included a behavioural change evoked more positive reactions towards the co-worker than vignettes without any behavioural change. Asking for workplace adjustments alone did not yield more positive reactions compared to not initiating any change. When preparing employees with interactional problems for their return to work, it is not effective to only instruct them on their statutory entitlement for workplace adjustments. Instead, it is advisable to encourage them to proactively strive for behaviour changes. PMID:26567587

    Recently, we have shown that C57BL/6J mice exhibit depression-like behavior under short photoperiod and suggested them as an animal model for investigating seasonal affective disorder (SAD). In this study, we tested if manipulations of the circadian clock with melatonin treatment could effectively modify depression-like and anxiety-like behaviors and brain serotonergic system in C57BL/6J mice. Under short photoperiods (8-h light/16-h dark), daily melatonin treatments 2 h before light offset have significantly altered the 24-h patterns of mRNA expression of circadian clock genes (per1, per2, bmal1 and clock) within the suprachiasmatic nuclei (SCN) mostly by increasing amplitude in their expressional rhythms without inducing robust phase shifts in them. Melatonin treatments altered the expression of genes of serotonergic neurotransmission in the dorsal raphe (tph2, sert, vmat2 and 5ht1a) and serotonin contents in the amygdala. Importantly, melatonin treatment reduced the immobility in forced swim test, a depression-like behavior. As a key mechanism of melatonin-induced antidepressant-like effect, the previously proposed phase-advance hypothesis of the circadian clock could not be confirmed under conditions of our experiment. However, our findings of modest adjustments in both the amplitude and phase of the transcriptional oscillators in the SCN as a result of melatonin treatments may be sufficient to associate with the effects seen in the brain serotonergic system and with the improvement in depression-like behavior. Our study confirmed a predictive validity of C57BL/6J mice as a useful model for the molecular analysis of links between the clock and brain serotonergic system, which could greatly accelerate our understanding of the pathogenesis of SAD, as well as the search for new treatments.

    Epidemiology is the study of disease distribution and factors determining or affecting it. Likewise, endodontic epidemiology can be defined as the science of studying the distribution pattern and determinants of pulp and periapical diseases; specially apical periodontitis. Although different study designs have been used in endodontics, researchers must pay more attention to study designs with higher level of evidence such as randomized clinical trials.

  9. [Schizoaffective disorder: An arguable diagnostic entity].

    2008-07-01

    Seventy-five years ago, J. Kasanin introduced the term "schizoaffective disorder" to refer to a disorder with symptoms of both schizophrenia and affective disorders. Since then, schizoaffective disorder has raised a considerable amount of discussion about its definition and position as a variant of schizophrenia, a variant of mood disorder or as an entity in between. This ambiguity is reflected on the definition of diagnostic criteria of the disorder in the taxonomic systems, which are practically too complex. Furthermore, there are essential differences between DSM-IV and ICD-10 regarding schizoaffective definition. Finally, the disorder has a very low inter-rater reliability and a very low longitudinal diagnostic stability. All the above have even led to proposals of elimination of schizoaffective disorder as a separate diagnostic entity. The prevalence of the disorder varies between 0.3% and 0.8%. Schizoaf fective disorder is more common in women than in men, a dif ference that is mostly attributed to increased incidence among women of the depressive type. The bipolar type of the disorder is more often found in young adults, whereas the depressive type is commoner in older adults. With regards to other variables such as educational level, marital status, prognosis, occupational level and social adjustment, schizoaffective disorder has more favourable characteristics than schizophrenia and less favourable than mood disorders. Age at onset is earlier than mood disorders and later than schizophrenia. The above epidemiologic and clinical data, as well as data from family, twin, genetic and neuroimaging studies, indicate that schizoaffective disorder can be best viewed as a mid-point on a continuum between schizophrenia and mood disorders and represents the most prominent paradigm challenging the so-called "Kraepelinian dichotomy" of major psychiatric disorders. Though schizoaffective disorder is a nosological nuisance, it is also a clinical reality and it is not

Methods:Totally 74 reemployment nurses who worked in a tertiary Grade A hospital in Jiangsu province for over half a year were recruited and interviewed by the Work Adjustment Disorder Scale, Organizational Citizenship Behavior Scale, Nurse Stressors Scale, and Nurse Career Identity Scale. Results:The mean score of work adjustment disorder among reemployment nurses was (22.60±3.74). Multiple linear regression analysis showed that nurse working stressors and job-hopping frequency were the predictors of work adjustment disorder among reemployment nurses. Conclusion:Nursing managers should analyze the reasons of working stressors among reemployment nurses, take effective measures to reduce their stress, pay attention to cultivate reemployment nurses' satisfaction and loyalty to the hospital and decrease their job-hopping frequency.

    Based on the Baltimore Epidemiologic Catchment Area (ECA) follow-up survey, we examined relationships between dimensions of Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) personality disorders and both subjective and objective memory functioning in a community population. Our study subjects consisted of 736 individuals from the ECA follow-up study of the original Baltimore ECA cohort, conducted between 1993 and 1996 and available for assessment in the Hopkins Epidemiology Study of Personality Disorders from 1997 to 1999. Subjects were assessed for DSM-IV personality disorders using a semi-structured instrument, the International Personality Disorder Examination, and were asked about a subjective appraisal of memory. Verbal memory function, including immediate recall, delayed recall, and recognition, were also evaluated. Multiple linear regression analyses were used to determine associations between personality dimensions of DSM-IV Axis II traits and subjective and objective memory functioning. Scores on schizoid and schizotypal personality dimensions were associated with subjective and objective memory dysfunction, both with and without adjustment for Axis I disorders. Borderline, antisocial, avoidant, and dependent personality disorder scores were associated with subjective memory impairment only, both with and without adjustment for Axis I disorders. This study suggests that subjective feelings of memory impairment and/or objective memory dysfunction are associated with specific personality disorder dimensions.

    2013-12-01

    Case definitions are critical in epidemiologic research. However, modern disease indicators must now consider complex data from gene-based research along with traditional clinical parameters. Rosacea is a skin disorder with multiple signs and symptoms. In individuals, these features may be multiple or one may predominate. While studies on the epidemiology of rosacea have previously been sparse, there has been a recent increase in research activity. A broader body of epidemiological information that includes a greater variety of countries beyond Northern Europe and general population-based demographics is needed. As there are operational issues in current case definitions of rosacea subtypes--rationalization and standardization--universal consistent applications in future research is also imperative. Further improvement in disease definition combining new research information along with clinical pragmatism should increase the accuracy of rosacea case ascertainment and facilitate further epidemiological research.

  4. Epidemiological causality.

    Science.gov (United States)

    Morabia, Alfredo

    2005-01-01

    Epidemiological methods, which combine population thinking and group comparisons, can primarily identify causes of disease in populations. There is therefore a tension between our intuitive notion of a cause, which we want to be deterministic and invariant at the individual level, and the epidemiological notion of causes, which are invariant only at the population level. Epidemiologists have given heretofore a pragmatic solution to this tension. Causal inference in epidemiology consists in checking the logical coherence of a causality statement and determining whether what has been found grossly contradicts what we think we already know: how strong is the association? Is there a dose-response relationship? Does the cause precede the effect? Is the effect biologically plausible? Etc. This approach to causal inference can be traced back to the English philosophers David Hume and John Stuart Mill. On the other hand, the mode of establishing causality, devised by Jakob Henle and Robert Koch, which has been fruitful in bacteriology, requires that in every instance the effect invariably follows the cause (e.g., inoculation of Koch bacillus and tuberculosis). This is incompatible with epidemiological causality which has to deal with probabilistic effects (e.g., smoking and lung cancer), and is therefore invariant only for the population.

    2014-01-01

    Full Text Available Growth and development of neuroepidemiology in India during the last four decades has been documented highlighting the historical milestones. The prevalence rates of the spectrum of neurological disorders from different regions of the country ranged from 967-4,070 with a mean of 2394 per 100000 population, providing a rough estimate of over 30 million people with neurological disorders (excluding neuroinfections and traumatic injuries. Prevalence and incidence rates of common disorders including epilepsy, stroke, Parkinson′s disease and tremors determined through population-based surveys show considerable variation across different regions of the country. The need for a standardized screening questionnaire, uniform methodology for case ascertainment and diagnosis is an essential requiste for generating robust national data on neurological disorders. Higher rates of prevalence of neurological disorders in rural areas, 6-8 million people with epilepsy and high case fatality rates of stroke (27-42% call for urgent strategies to establish outreach neurology services to cater to remote and rural areas, develop National Epilepsy Control Program and establish stroke units at different levels of health care pyramid.

  10. Epidemiological studies in psychosomatic medicine.

    Science.gov (United States)

    Eastwood, M R

    1975-01-01

    The epidemiological triad of host, agent and environment used conceptually in infectious disease may serve as a model for psychosomatic disorders, despite the involvement of many more variables. There are major problems with diagnosis and measurement, however, and the term "psychosomatic" has several meanings. The two main senses are "specific" psychosomatic disorders and an ecological view of illness. The association between psychiatric and physical disorder has been examined in a variety of settings and the findings have suggested that there is a positive relationship. Despite considerable methodological and sampling difficulties in epidemiological research into psychosomatic illness, recent efforts have been made to overcome these. The results of ecological studies appear to be more consistent that those dealing with "specific" psychosomatic disorders and suggest that man has a general psychophysical propensity to disease. Although physical and mental illness do seem to be intimately linked, the reasons for "vulnerability" to illness and "clustering" of illness are obscure. The clarification of these areas appears to be the main task ahead for epidemiology in the field of psychosomatic medicine. PMID:773850

    This study describes medical conditions experienced by a population-based cohort of adults with autism spectrum disorder whose significant developmental concerns were apparent during childhood. As part of a 25-year outcome study of autism spectrum disorder in adulthood, medical histories were collected on 92 participants (N = 69 males) who were first ascertained as children in the mid-1980s, 11 of whom were deceased at the time of follow-up. Questionnaires queried medical symptoms, disorders, hospitalizations, surgeries, and medication use. Median age at follow-up was 36 years (range: 23.5-50.5 years), and intellectual disability co-occurred in 62%. The most common medical conditions were seizures, obesity, insomnia, and constipation. The median number of medical conditions per person was 11. Increased medical comorbidity was associated with female gender (p = 0.01) and obesity (p = 0.03), but not intellectual disability (p = 0.79). Adults in this cohort of autism spectrum disorder first ascertained in the 1980s experience a high number of chronic medical conditions, regardless of intellectual ability. Understanding of these conditions commonly experienced should direct community-based and medical primary care for this population. PMID:26162628

    1989-01-01

    The literature published between 1965 and 1989 on the cancer epidemiology of woodworking in furniture industries and carpentry shops in 17 countries is reviewed. Included are some unpublished data obtained through personal communication with epidemiologists or collected from doctoral dissertations. Of 5,785 cases with sino-nasal cancers, about 23% were found to be woodworkers. Dusty jobs, especially wood processing using high-speed machines, are mainly associated with the enhanced incidence of nasal adenocarcinomas. The latency periods of the latter tumors ranged from 7 to 69 years in five European countries. A variety of neoplasias of the respiratory, digestive, and urinary tracts as well as the hemopoietic and lymphatic systems, including Hodgkin's disease are reported to be significantly associated with occupational exposure to wood dust. These data suggest that the exposure to some types of wood dust might cause a systemic rather than local neoplastic disorder.

Generation Scotland: Scottish Family Health Study (GS:SFHS is a large (n = 20,198, family-based population study designed to identify the genetic determinants of common diseases, including Major Depressive Disorder. Two thousand seven hundred and six individuals were SCID diagnosed with MDD, 13.5% of the cohort, from which we inferred a population prevalence of 12.2% (95% credible interval: 11.4% to 13.1%. Increased risk of MDD was associated with being female, unemployed due to a disability, current smokers, former drinkers, and living in areas of greater social deprivation. The heritability of MDD in GS:SFHS was between 28% and 44%, estimated from a pedigree model. The genetic correlation of MDD between sexes, age of onset, and illness course were examined and showed strong genetic correlations. The genetic correlation between males and females with MDD was 0.75 (0.43 to 0.99; between earlier (≤ age 40 and later (> age 40 onset was 0.85 (0.66 to 0.98; and between single and recurrent episodic illness course was 0.87 (0.72 to 0.98. We found that the heritability of recurrent MDD illness course was significantly greater than the heritability of single MDD illness course. The study confirms a moderate genetic contribution to depression, with a small contribution of the common family environment (variance proportion = 0.07, CI: 0.01 to 0.15, and supports the relationship of MDD with previously identified risk factors.

    Full Text Available Intermittent explosive disorder is an impulse control disorder characterized by the occurrence of discrete episodes of failure to resist aggressive impulses that result in violent assault or destruction of property. Though the prevalence intermittent explosive disorder has been reported to be relatively rare in frontier studies on the field, it is now common opinion that intermittent explosive disorder is far more common than previously thought especially in clinical psychiatry settings. Etiological studies displayed the role of both psychosocial factors like childhood traumas and biological factors like dysfunctional neurotransmitter systems and genetics. In differential diagnosis of the disorder, disorders involving agression as a symptom such as alcohol and drug intoxication, antisocial and borderline personality disorders, personality changes due to general medical conditions and behavioral disorder should be considered. A combination of pharmacological and psychotherapeutic approaches are suggested in the treatment of the disorder. This article briefly reviews the historical background, diagnostic criteria, epidemiology, etiology and treatment of intermittent explosive disorder.

Although prior studies have evaluated epidemiologic patterns of acne vulgaris in various ethnicities and regions, adequate understanding of the worldwide burden of the disease associated with patients in their late adolescence (15–19-year olds remains lacking. Objective: To assess the global burden of the disease associated with acne vulgaris for late adolescents (15–19-year olds and provide an overview of the epidemiology, pathophysiology, and treatment options for acne in this population. Design: Database summary study. Setting: Global Burden of Disease Study 2010 database. Participants: Global Burden of Disease regions comprised countries with prevalence of acne vulgaris between the ages of 15 and 19 years. Main outcomes and measures: Geographic region-level disability-adjusted life year rates (per 100,000 persons associated with acne vulgaris in years 1990 through 2010. Median percentage change in disability-adjusted life year rates was estimated for each region across the specified study period. Conclusion and relevance: Acne vulgaris-associated disease burden exhibits global distribution and has continued to grow in prevalence over time within this population. This continued growth suggests an unmet dermatologic need worldwide for this disorder and potential opportunities for improved access and delivery of dermatologic care.

AA is clinically heterogenous, and its natural history is unpredictable. There is no preventative therapy or cure.Objective: The objective of this study is to provide an evidence-based systematic review on the epidemiology and the burden of AA.Methods and selection criteria: A search was conducted of the published, peer-reviewed literature via PubMed, Embase, and Web of Science. Studies published in English within the last 51 years that measured AA’s incidence, prevalence, distribution, disability-adjusted life years (DALYs, quality of life, and associated psychiatric and medical comorbidities were included. Two authors assessed studies and extracted the data.Results: The lifetime incidence of AA is approximately 2% worldwide. Both formal population studies found no sex predominance. First onset is most common in the third and fourth decades of life but may occur at any age. An earlier age of first onset corresponds with an increased lifetime risk of extensive disease. Global DALYs for AA were calculated at 1,332,800 in 2010. AA patients are at risk for depression and anxiety, atopy, vitiligo, thyroid disease, and other autoimmune conditions.Conclusion: AA is the most prevalent autoimmune disorder and the second most prevalent hair loss disorder after androgenetic alopecia, and the lifetime risk in the global population is approximately 2%. AA is associated with psychiatric and medical comorbidities including depression, anxiety, and several autoimmune disorders, and an increased global burden of disease.Keywords: hair loss, hair, prevalence, incidence, burden of disease

    Recent epidemiological data suggest that the lifetime prevalence of gambling problems differs depending on race-ethnicity. Understanding variations in disease presentation in blacks and whites, and relationships with biological and sociocultural factors, may have implications for selecting appropriate prevention strategies. 62 non-treatment seeking volunteers (18-29 years, n=18 [29.0%] female) with gambling disorder were recruited from the general community. Black (n=36) and White (n=26) participants were compared on demographic, clinical and cognitive measures. Young black adults with gambling disorder reported more symptoms of gambling disorder and greater scores on a measure of compulsivity. In addition they exhibited significantly higher total errors on a set-shifting task, less risk adjustment on a gambling task, greater delay aversion on a gambling task, and more total errors on a working memory task. These findings suggest that the clinical and neurocognitive presentation of gambling disorder different between racial-ethnic groups. PMID:27262266

    Full Text Available Anxiety disorders are a highly prevalent and disabling class of psychiatric disorders. Anxiety disorders are highly prevalent and associated with substantial distress, morbidity and mortality. Recent epidemiological studies of anxiety disorders provided evidence of their high frequency in the general population worldwide. Anxiety disorders afflict an estimated 15.7 million people in the United States each year. Anxiety disorders are highly prevalent in adults with females showing higher preponderance of 2:1 as compared to males. Anxiety disorders are a group of mental disorders characterized by various combinations of key features - Irritability, fear, Insomnia, Nervousness, Tachycardia, Inability to concentrate, poor coping skills, Palpitation, Sweating, Agoraphobia and Social Withdrawal. The anxiety disorders, including panic disorder (PD, generalized anxiety disorder (GAD, social anxiety disorder (SAD, and posttraumatic stress disorder (PTSD, are among the disabling medical disorders. The neurobiology of anxiety disorders is not fully understood, but several different biologic abnormalities have been implicated in their etiology. The GABA, NE and 5HT systems play crucial roles in mediating the affective circuitry underlying the highly related clinical disorders of anxiety. Anxiety is a common psychiatric condition characterized by unnecessary aggression, poor quality of life, fear, worry, avoidance, and compulsive rituals that are associated with significant distress.

    2014-06-01

    Full Text Available Assessment of studies related with bipolar disorder in Turkey did not reveal an epidemiologically qualified field study. Most of the studies are hospital based or clinical studies which did not include a systematical scanning and did not aim to collect any epidemiological data and transfer information to health authorities. The generalizability of these studies to our community is far from being valid and reliable. On the other hand, a profile which will be created by reviewing the findings of these studies performed in various regions of Turkey will have a contribution to knowing the and ldquo;unique to us and rdquo; features of bipolar disorder and determining cultural risk factors. All this information can constitute a basis for formation and development of public mental health services related with bipolar disorder. In Turkey, the need for epidemiologically significant, polycentric, public sampled studies with broad participation is indispensable. Although our psychiatric epidemiology and clinical studies include necessary scientific basis, they are not powerful enough to evaluate the authentic and progressional relations such as rapid urbanization and immigration. The aim of this review is to evaluate and discuss prominent epidemiological findings, deficiencies and possibile future activities related with studies conducted in Turkey about bipolar disorder..

    It is well recognized that mood disorders and epilepsy commonly co-occur. Despite this, our knowledge regarding the relationship between epilepsy and bipolar disorder is limited. Several shared features between the two disorders, such as their episodic nature and potential to run a chronic course, and the efficacy of some antiepileptic medications in the prophylaxis of both disorders, are often cited as evidence of possible shared underlying pathophysiology. The present paper aims to review the bidirectional associations between epilepsy and bipolar disorder, with a focus on epidemiological links, evidence for shared etiology, and the impact of these disorders on both the individual and wider society. Better recognition and understanding of these two complex disorders, along with an integrated clinical approach, are crucial for improved evaluation and management of comorbid epilepsy and mood disorders.

    Objective To investigate the prevalence of four common neuropsychiatric disorders in Tibet, with an aim to providing information support to health planning. Methods The survey was carried out in four regions of Tibet. The sampling strategy was adapted from that of a national psychiatric epidemiological survey in China in 1982 and 1993. The Neurosis Screening Inventory, Screening Inventory for Alcohol Dependence and Related Problems, Child Intelligence Screening Inventory, and a questionnaire for the Detection of Epileptic Seizures were administered to the respondents through face to face interview. Those with a positive response and 10% of those with a negative response were further interviewed with the Structured Clinical Interview for DSM-IV Axis I Disorders (research version) (SCID-1 ). Anxiety disorders and alcohol used disorders were diagnosed according to the American Psychiatric Association: Diagnostic and Statistical Manual of Mental Disorders (4th edition) (DSM-IV). Hysteria and mental retardation were diagnosed according to the International Classification of Diseases, 10th edition (ICD10), and the Chinese Classification of Mental Disorders, 3rd edition (CCMD-3). Results The point prevalence of neuroses, alcohol-related disorders, mental retardation and epilepsy was 2. 56%, 4. 06%, 0. 28% and 0. 68%, respectively. The lifetime prevalence of neuroses, alcohol-related disorders, mental retardation and epilepsy was 2. 62% , 4. 24% , 0. 28% and 0. 72% , respectively. Conclusion Alcohol-related disorders and neuroses are the two common mental health problems in Tibet. Mental retardation and epilepsy are the two serious neuropsychiatric disorders affecting Tibetan children and adolescence. These disorders should be identified as priorities in the reginonal health planning in Tibet.%目的 了解神经症、酒使用障碍、精神发育迟滞和癫痫这4类常见的神经精神障碍在西藏的流行情况,为政府制订卫生

  14. Association Between Cannabis and Psychosis: Epidemiologic Evidence.

    Science.gov (United States)

    Gage, Suzanne H; Hickman, Matthew; Zammit, Stanley

    2016-04-01

    Associations between cannabis use and psychotic outcomes are consistently reported, but establishing causality from observational designs can be problematic. We review the evidence from longitudinal studies that have examined this relationship and discuss the epidemiologic evidence for and against interpreting the findings as causal. We also review the evidence identifying groups at particularly high risk of developing psychosis from using cannabis. Overall, evidence from epidemiologic studies provides strong enough evidence to warrant a public health message that cannabis use can increase the risk of psychotic disorders. However, further studies are required to determine the magnitude of this effect, to determine the effect of different strains of cannabis on risk, and to identify high-risk groups particularly susceptible to the effects of cannabis on psychosis. We also discuss complementary epidemiologic methods that can help address these questions.

    Full Text Available Expatriation is a widely studied area of research in work and organizational psychology. After expatriates accomplish their missions in host countries, they return to their countries and this process is called repatriation. Adjustment constitutes a crucial part in repatriation research. In the present literature review, research about repatriation adjustment was reviewed with the aim of defining the whole picture in this phenomenon. Present research was classified on the basis of a theoretical model of repatriation adjustment. Basic frame consisted of antecedents, adjustment, outcomes as main variables and personal characteristics/coping strategies and organizational strategies as moderating variables.

  16. Making psychiatric epidemiology useful: the contribution of epidemiology to government policy.

    Jenkins, R

    2003-01-01

    This paper aims to discuss the contribution of epidemiology to aspects of public policy that have either a direct influence on mental health and mental disorders, or an indirect effect by influencing environmental factors which influence mental health. Both kinds of public policy will need to be considered by governments wishing to protect, promote, and improve the mental health of their populations. The paper draws on information from both relatively wealthy and low-income countries. The paper defines epidemiology and mental health policy, sets out the range of government policies which may have an impact on mental health, and explores the ways in which epidemiology may contribute to mental health policy in relation to service inputs, processes and outcomes as well as to wider government policies. The paper also examines the advantages and disadvantages of different sources of data. There are a number of reasons to carry out large-scale surveys of psychiatric morbidity. First, effective policy should address the needs of the population, which can best be assessed by the epidemiology and the social and economic causes and consequences of psychiatric morbidity. Secondly, representative information in a defined geographic area can document the use of existing services and can estimate the extent of unmet needs and the services required meeting those needs. Thirdly, valid information on prevalence and associated risk factors of presumed causal importance allow aetiological hypotheses to be generated and tested and models developed for prevention. Finally, by repeating community surveys, it is possible to monitor the health of the population and trends. Epidemiological findings emphasize the importance of mental health policy addressing the key role of primary care, the social context and social consequences of disorder, the importance of addressing services for children, the need to reduce premature mortality from suicide and from physical illness.

    This review article outlines the key concepts in vaccine epidemiology, such as basic reproductive numbers, force of infection, vaccine efficacy and effectiveness, vaccine failure, herd immunity, herd effect, epidemiological shift, disease modeling, and describes the application of this knowledge both at program levels and in the practice by family physicians, epidemiologists, and pediatricians. A case has been made for increased knowledge and understanding of vaccine epidemiology among key stakeholders including policy makers, immunization program managers, public health experts, pediatricians, family physicians, and other experts/individuals involved in immunization service delivery. It has been argued that knowledge of vaccine epidemiology which is likely to benefit the society through contributions to the informed decision-making and improving vaccination coverage in the low and middle income countries (LMICs). The article ends with suggestions for the provision of systematic training and learning platforms in vaccine epidemiology to save millions of preventable deaths and improve health outcomes through life-course.

    Epidemiology of acromegaly in Spain does not differ from that reported in other published series. Prevalence rate is approximately 60 cases per million, peak incidence occurs in middle age, more women are affected (61%), and there is a substantial delay between occurrence of the first symptoms and diagnosis. Studies REA (Spanish Acromegaly Registry) and OASIS analyzed the epidemiology, clinical characteristics, and management of the disease in Spain. Surgery, performed in more than 80% of patients, has been (and continues to be) the main treatment for the past four decades. In the past decade, however, more patients have received somatostatin analogs (SSAs) as first-line treatment. Use of radiation therapy has significantly decreased in recent decades. Somatostatin analogs (SSAs) are the most commonly used drugs, administered to 85% of patients; however, only 12%-15% continue on drug treatment alone. The surgical remission rate was 38.4% in the last decade, with a significant improvement over decades. Preoperative treatment with SSAs has no influence on surgical cure rates. Second-line therapies used after surgical failure in the past decade included SSAs in 49% of patients, repeat surgery in 27%, radiotherapy in 11%, pegvisomant in 15%, and dopamine agonists in 5%. Mean cost of acromegaly treatment was 9.668€ (data estimated in 2009 and adjusted in 2010), of which 71% was due to the cost of SSAs. Patients treated with pegvisomant have a more aggressive form of the disease and higher comorbidity rates.

    Full Text Available We used a national online registry to examine variation in cumulative prevalence of community diagnosis of psychiatric comorbidity in 4343 children with autism spectrum disorders (ASD. Adjusted multivariate logistic regression models compared influence of individual, family, and geographic factors on cumulative prevalence of parent-reported anxiety disorder, depression, bipolar disorder, and attention deficit/hyperactivity disorder or attention deficit disorder. Adjusted odds of community-assigned lifetime psychiatric comorbidity were significantly higher with each additional year of life, with increasing autism severity, and with Asperger syndrome and pervasive developmental disorder—not otherwise specified compared with autistic disorder. Overall, in this largest study of parent-reported community diagnoses of psychiatric comorbidity, gender, autistic regression, autism severity, and type of ASD all emerged as significant factors correlating with cumulative prevalence. These findings could suggest both underlying trends in actual comorbidity as well as variation in community interpretation and application of comorbid diagnoses in ASD.

    创伤后应激障碍(PTSD)是由暴露于生命威胁事件而产生的一种受迫害的感觉,其呈现出的三大特征性症候群包括侵害性症状、逃避症状及易于唤醒症状.关于PTSD流行病学研究的文献很多,但其结果因各自研究对象和评价方法的不同而有所差异.针对难民、迁徙人群及社区人群的研究受到对战争创伤的定义不同、样本选择的不同以及是否进行心理干预等因素的影响而存在较大差异.因此,对战争创伤或精神折磨后平民中PTSD的发病率尚无准确结论.目前针对PTSD的研究存在的不足:一是既往研究分析方法存在差异,不同研究小组间的统计结果也存在差异;现有研究均针对非西方种族及某些特定人群,采用的样本尚存在选择性偏倚.二是绝大多数研究未设置对照组,所得结果缺乏可靠性及通用性.三是战后PTSD的研究应重视国籍及文化背景的影响.PTSD流行病学研究领域还有大量工作要做,建立适合中国人群的简易PTSD筛查和测量工具,开展各类创伤性事件后PTSD发病率及其分布特征的调研,对于PTSD的有效防治具有重要意义.%Post-traumatic stress disorder (PTSD) is a feeling of persecution arising from the exposure to a life-threatening event. PTSD shows three kinds of characteristic syndrome including invasive, evading, and easy-to-wake up syndromes. Numerous literature had been published on the study of the PTSD epidemiology. However, research results varied due to different research subjects and evaluation methods used. A big difference exists among studies on refugees, migrating people, and community population, because these studies are affected by different definition of war trauma, difference in choice of samples, and application of psychological intervention. Therefore, no exact conclusions have been established on the accurate incidence of PTSD in civilians after having endured the trauma of war or mental

    Full Text Available Psychosocial adjustment and premorbid personality are two factors that are frequently studied in order to elucidate the etiopathogenesis of schizophrenia. Premorbid adjustment alterations and personality disorders (principally those of the schizophrenia spectrum have been considered vulnerability elements or have been linked with the early manifestations of a disease that is still underdeveloped (hypothesis of neurodevelopment. In this paper we review the literature. We also studied the relationship between premorbid adjustment (PAS scale and previous personality disorders (SCID-II in a sample of 40 patients with schizophrenia (DSM-III-R, DSM-IV, CIE-10, and statistically correlated them. The results show that premorbid adjustment correlates with avoidant, schizotypal and schizoid personality disorders: the more personality pathology found, the poorer is the premorbid psychosocial adjustment. Premorbid adjustment positively correlates with histrionic personality traits. The pathological traits of schizotypal and schizoid personalities account for up to 77% of the variance of the total premorbid adjustment in schizophrenic patients. Conclusion: The degrees of premorbid adjustment in schizophrenia are related to the different premorbid personality disorders of schizophrenic patients, which are mainly those most genetically related with schizophrenia, that is, the spectrum of the schizophrenia.

    Evolutionary biology, which aims to explain the dynamic process of shaping the diversity of life, has not yet significantly affected thinking in social epidemiology. Current challenges in social epidemiology include understanding how social exposures can affect our biology, explaining the dynamics of society and health, and designing better interventions that are mindful of the impact of exposures during critical periods. I review how evolutionary concepts and tools, such as fitness gradient in cultural evolution, evolutionary game theory, and contemporary evolution in cancer, can provide helpful insights regarding social epidemiology.

    Science.gov (United States)

    Anderson, Walter L.

    1969-01-01

    The variation of coordinates method is employed to perform a weighted least squares adjustment of horizontal survey networks. Geodetic coordinates are required for each fixed and adjustable station. A preliminary inverse geodetic position computation is made for each observed line. Weights associated with each observed equation for direction, azimuth, and distance are applied in the formation of the normal equations in-the least squares adjustment. The number of normal equations that may be solved is twice the number of new stations and less than 150. When the normal equations are solved, shifts are produced at adjustable stations. Previously computed correction factors are applied to the shifts and a most probable geodetic position is found for each adjustable station. Pinal azimuths and distances are computed. These may be written onto magnetic tape for subsequent computation of state plane or grid coordinates. Input consists of punch cards containing project identification, program options, and position and observation information. Results listed include preliminary and final positions, residuals, observation equations, solution of the normal equations showing magnitudes of shifts, and a plot of each adjusted and fixed station. During processing, data sets containing irrecoverable errors are rejected and the type of error is listed. The computer resumes processing of additional data sets.. Other conditions cause warning-errors to be issued, and processing continues with the current data set.

    We examined the relationship between characteristics associated with autism spectrum disorder and college adjustment in a sample of neurotypical college students. Using the Broad Autism Phenotype Questionnaire and the Student Adaptation to College Questionnaire, we found that higher levels of autism spectrum disorder characteristics were associated with poorer adjustment to college. One subscale of the Broad Autism Phenotype Questionnaire, pragmatic language difficulties, explained the most variance in adjustment. In addition, students who met the previously established cut-off scores for possessing the broad autism phenotype scored significantly lower on all Student Adaptation to College Questionnaire subscales. Finally, pragmatic language difficulties mediated the relationship between college major and academic adjustment. These findings underscore the need for future research to examine how pragmatic language difficulties may impede college success in students with autism spectrum disorder and in the typical population.

    Knowledge of the epidemiology of tobacco use and dependence can be used to guide research initiatives, intervention programs, and policy decisions. Both the reduction in the prevalence of smoking among US adults and black adolescents and the decline in per capita consumption are encouraging. These changes have probably been influenced by factors operating at the individual (e.g., school-based prevention programs and cessation programs) and environmental (e.g., mass media educational strategies, the presence of smoke-free laws and policies, and the price of tobacco products) levels (for a discussion of these factors, see, e.g., refs. 2, 48, 52, 183, and 184). The lack of progress among adolescents, especially whites and males, and the high risk for experimenters of developing tobacco dependence present cause for great concern (48, 183-186). In addition to those discussed above, several areas of research can be recommended. 1. Better understanding of the clustering of tobacco use with the use of other drugs, other risk behaviors, and other psychiatric disorders could better illuminate the causal processes involved, as well as the special features of the interventions needed to prevent and treat tobacco dependence. 2. To better understand population needs, trend analyses of prevalence, initiation, and cessation should, whenever possible, incorporate standardized measures of these other risk factors. Future research should compare the effect of socioeconomic status variables on measures of smoking behavior among racial/ethnic groups in the United States. 3. For reasons that may be genetic, environmental, or both, some persons do not progress beyond initial experimentation with tobacco use (2, 48, 183, 187-192), but about one-third to one-half of those who experiment with cigarettes become regular users (48, 193, 194). Factors, both individual and environmental, that can influence the susceptibility of individuals to tobacco dependence need further attention. 4. To

    2016-01-01

    Although the use of phylogenetic trees in epidemiological investigations has become commonplace, their epidemiological interpretation has not been systematically evaluated. Here, we use an HIV-1 within-host coalescent model to probabilistically evaluate transmission histories of two epidemiologically linked hosts. Previous critique of phylogenetic reconstruction has claimed that direction of transmission is difficult to infer, and that the existence of unsampled intermediary links or common sources can never be excluded. The phylogenetic relationship between the HIV populations of epidemiologically linked hosts can be classified into six types of trees, based on cladistic relationships and whether the reconstruction is consistent with the true transmission history or not. We show that the direction of transmission and whether unsampled intermediary links or common sources existed make very different predictions about expected phylogenetic relationships: (i) Direction of transmission can often be established when paraphyly exists, (ii) intermediary links can be excluded when multiple lineages were transmitted, and (iii) when the sampled individuals’ HIV populations both are monophyletic a common source was likely the origin. Inconsistent results, suggesting the wrong transmission direction, were generally rare. In addition, the expected tree topology also depends on the number of transmitted lineages, the sample size, the time of the sample relative to transmission, and how fast the diversity increases after infection. Typically, 20 or more sequences per subject give robust results. We confirm our theoretical evaluations with analyses of real transmission histories and discuss how our findings should aid in interpreting phylogenetic results. PMID:26903617

    Credit risk has become a topical issue since the 2007 Credit Crisis, particularly for its impact on the valuation of OTC derivatives. This becomes critical when the credit risk of entities involved in a contract either as underlying or counterparty become highly correlated as is the case during macroeconomic shocks. It impacts the valuation of such contracts through an additional term, the credit valuation adjustment (CVA). This can become large with such correlation. This thesis outlines the...

  20. Fiscal adjustment in Brazil

    2003-03-01

    Full Text Available Two questions are addressed in this paper. The first one is the determination of periods of fiscal consolidation and fiscal stimulus. The second one is the importance of the composition of fiscal adjustments for their success, defined as a declining debt to GDP ratio. We, characterize 1994 and 1999 as points of fiscal consolidation. The 1994 consolidation can not be considered successful since after that period the debt to GDP ratio has grown continuously. The adjustment can be characterized as a type 2 adjustment (Alesina and Perotti (1997 in the sense that cuts were made mainly in public investment, while government wages and transfers remained almost unchanged. This type of adjustment usually has a low likelihood of being a success.Duas questões são tratadas neste artigo. A primeira é a determinação dos períodos de consolidação fiscal e estímulo fiscal. A segunda questão é a importância da composição dos ajustamentos fiscais para o seu sucesso, definido como um declínio na razo dívida/PIB. Nós, caracterizamos 1994 e 1999 como pontos de consolidação fiscal. A consolidação de 1994 não pode ser considerada um sucesso pois nos anos seguintes a razão dívida/PIB cresceu continuamente. O ajustamento pode ser considerado como um ajustamento do tipo 2 (Alesina and Perotti, 1997 no sentido de que foram feitos cortes principalmente no investimento público, enquanto os salários e transferências permaneceram praticamente inalterados. Este tipo de ajustamento geralmente tem uma baixa probabilidade de sucesso.

    Few epidemiological studies have investigated the role of hypertensive disorders of pregnancy in the aetiology of childhood respiratory and atopic outcomes.In the Avon Longitudinal Study of Parents and Children we examined associations of maternal gestational hypertension, hypertension before pregnancy and pre-eclampsia with wheezing at 18 months, wheezing and asthma at 7 years and lung function at 8-9 years, after controlling for potential confounders (n=5322-8734, depending on outcome).Gestational hypertension was not associated with any of the outcomes. There was weak evidence for a positive association between pre-eclampsia and early wheezing (adjusted OR 1.31, 95% CI 0.94-1.82, compared to normotensive pregnancies) and for negative associations between pre-eclampsia and forced expiratory volume in 1 s (adjusted mean difference in sd score -0.14, 95% CI -0.33-0.06) and maximal mid-expiratory flow (-0.15, 95% CI -0.34-0.04). Hypertension before pregnancy was positively associated with wheezing (OR 1.63, 95% CI 1.16-2.31) and asthma (OR 1.34, 95% CI 1.00-1.79).Gestational hypertension is unlikely to be a risk factor for childhood respiratory disorders; hypertension before pregnancy may be a risk factor for childhood wheezing and asthma, but this finding needs replication. Larger studies are needed to confirm whether pre-eclampsia is associated with impaired childhood lung function.

    2015-02-01

    Full Text Available Uncertainty often exists in the process of obtaining measurement data, which affects the reliability of parameter estimation. This paper establishes a new adjustment model in which uncertainty is incorporated into the function model as a parameter. A new adjustment criterion and its iterative algorithm are given based on uncertainty propagation law in the residual error, in which the maximum possible uncertainty is minimized. This paper also analyzes, with examples, the different adjustment criteria and features of optimal solutions about the least-squares adjustment, the uncertainty adjustment and total least-squares adjustment. Existing error theory is extended with new observational data processing method about uncertainty.

    Vigo, Daniel V; Selle, Valerio; Baldessarini, Ross

    2013-01-01

    Pain disorders are extraordinarily prevalent throughout clinical medicine, and are highly co-morbid with various psychiatric disorders, particularly those including depression or anxiety. Assessment of such patients tends to be based on diagnostic criteria that may not reflect the complexity of the clinical problem and can result in prioritizing somatic aspects of painful syndromes at the expense of psychiatric aspects or, conversely, over-emphasize psychiatric aspects. In the first part of this overview we consider current nosological perspectives and their potential clinical consequences, epidemiological data that underscore the association of comorbid painful and affective or anxious syndromes, and consider the importance of psychiatric assessment and treatment of such patients. The major overlap between pain disorders and psychiatric disorders, as well as the unsatisfactory state of treatments available for chronic pain syndromes, encourage a comprehensive approach to assessing and clinically managing patients with chronic pain. Many programs for pain disorder patients offer narrowly specialized treatment options. To be preferred are multi-disciplinary teams with expertise in internal medicine, neurology, pain management, and rehabilitation, as well as psychology and psychiatry. In the second part of this overview, we propose that psychiatrists can serve a key role in leading comprehensive assessment and management of complex and challenging pain-psychiatric patients who are typically only partially responsive to available treatments.

    2014-01-01

    Emotion dysregulation is a core feature of chronic complex dissociative disorders (DD), as it is for borderline personality disorder (BPD). Chronic complex DD include dissociative identity disorder (DID) and the most common form of dissociative disorder not otherwise specified (DDNOS, type 1), now known as Other Specified Dissociative Disorders (OSDD, type 1). BPD is a common comorbid disorder with DD, although preliminary research indicates the disorders have some distinguishing features as well as considerable overlap. This article focuses on the epidemiology, clinical presentation, psychological profile, treatment, and neurobiology of chronic complex DD with emphasis placed on the role of emotion dysregulation in each of these areas. Trauma experts conceptualize borderline symptoms as often being trauma based, as are chronic complex DD. We review the preliminary research that compares DD to BPD in the hopes that this will stimulate additional comparative research. PMID:26401297

    2016-01-01

    Colorectal cancer is currently the third deadliest cancer in the United States and will claim an estimated 49,190 U.S. lives in 2016. The purpose of this review is to summarize our current understanding of this disease, based on nationally published statistics and information presented in peer-reviewed journal articles. Specifically, this review will cover the following topics: descriptive epidemiology (including time and disease trends both in the United States and abroad), risk factors (environmental, genetic, and gene-environment interactions), screening, prevention and control, and treatment. Landmark discoveries in colorectal cancer risk factor research will also be presented. Based on the information reviewed for this report, we suggest that future U.S. public health efforts aim to increase colorectal cancer screening among African American communities, and that future worldwide colorectal cancer epidemiology studies should focus on researching nutrient-gene interactions towards the goal of improving personalized treatment and prevention strategies.

    Science.gov (United States)

    Assennato, G; Bisceglia, L

    2003-01-01

    The development of Occupational Epidemiology in Italy is closely correlated with the political and social awareness of the needs of preventive strategies in the workplace. In the late '60s the Trade Unions supported a model of intervention based on the involvement of the so-called "Homogeneous group of workers" in the validation of the preventive measures taken on the workplace. In spite of the shortcomings of the model, it was extremely effective resulting in enhanced perception of the priority of preventive strategies and in the formation within the National Health Service of the Occupational Health Services. In Italy over the period 1973-2002 there has been an impressive trend of research in field of occupational epidemiology (a search on Medline shows an increasing trend over the years and, in terms of international comparison, higher figures than in Germany, France and Spain). Occupational Epidemiology is now present in the activities of the local Occupational Health Services and in the teaching activities of the Medical Schools throughout the country. PMID:14582235

    2006-01-01

    Epidemiological evidence has concurred with clinical and experimental evidence to correlate current levels of ambient air pollution, both indoors and outdoors, with respiratory effects. In this respect, the use of specific epidemiological methods has been crucial. Common outdoor pollutants are particulate matter, nitrogen dioxide, carbon monoxide, volatile organic compounds and ozone. Short-term effects of outdoor air pollution include changes in lung function, respiratory symptoms and mortality due to respiratory causes. Increase in the use of health care resources has also been associated with short-term effects of air pollution. Long-term effects of cumulated exposure to urban air pollution include lung growth impairment, chronic obstructive pulmonary disease (COPD), lung cancer, and probably the development of asthma and allergies. Lung cancer and COPD have been related to a shorter life expectancy. Common indoor pollutants are environmental tobacco smoke, particulate matter, nitrogen dioxide, carbon monoxide, volatile organic compounds and biological allergens. Concentrations of these pollutants can be many times higher indoors than outdoors. Indoor air pollution may increase the risk of irritation phenomena, allergic sensitisation, acute and chronic respiratory disorders and lung function impairment. Recent conservative estimates have shown that 1.5-2 million deaths per year worldwide could be attributed to indoor air pollution. Further epidemiological research is necessary to better evaluate the respiratory health effects of air pollution and to implement protective programmes for public health.

    Tanjore Reena

    2006-01-01

    Full Text Available Background: Hypertrophic cardiomyopathy (HCM is a heart muscle disorder and is known to be inherited as an autosomal dominant trait. Mutations in several sarcomeric, cytoskeletal and mitochondrial genes have been reported in HCM. Though many cases of HCM are being identified, there is limited data regarding the epidemiology and genetics of HCM in India. Aim: Therefore the present study is envisaged at identifying the epidemiological variables in HCM and fitting a probability model assuming dominant mode of inheritance in HCM, which may in turn shed light on the heterogeneity of this complex disorder. Materials AND Methods: The 127 HCM cases were divided into subtypes based on pattern of hypertrophy. Chi square analysis, odds ratio, probability, relative frequency, penetrance and heritability estimates were calculated apart from epidemiological variables. Results: The HCM subtypes revealed the heterogeneous nature of the condition suggesting that the genes/mutations involved in their pathogenesis are different and this is supported by distinctive differences observed in their probability, heritability and penetrance estimates apart from epidemiological variables. An increased male preponderance was observed with the sex ratio being 3.7:1. The age at onset was found to be more than a decade early in familial cases (30 ± 10 yrs compared to non familial cases (44 ± 14 yrs. Chi square analysis revealed obstructive HCM to be following autosomal dominant mode of inheritance where as non-obstructive HCM was significantly deviating. The level of deviation was significantly high for the middle onset group compared to early and late onset groups, therefore this group may be considered as an admixture wherein genes/gene modifiers and environmental variables may be contributing to the heterogeneity and this is further supported by odds ratio. Conclusions: The study thus brings out the complexity of HCM and suggests that modes of inheritance other than

    Hansen, Frank

    2008-01-01

    We extend the concept of Wigner-Yanase-Dyson skew information to something we call "metric adjusted skew information" (of a state with respect to a conserved observable). This "skew information" is intended to be a non-negative quantity bounded by the variance (of an observable in a state......) that vanishes for observables commuting with the state. We show that the skew information is a convex function on the manifold of states. It also satisfies other requirements, proposed by Wigner and Yanase, for an effective measure-of-information content of a state relative to a conserved observable. We...... establish a connection between the geometrical formulation of quantum statistics as proposed by Chentsov and Morozova and measures of quantum information as introduced by Wigner and Yanase and extended in this article. We show that the set of normalized Morozova-Chentsov functions describing the possible...

She introduces process philosophy and complexity theory to research on organizational socialization and newcomer innovation. The study challenges assumptions...... in standardized induction programs where newcomers are cast in roles as insecure novices needing to be “taught the ropes” of the organizational culture. Linked with this, it is suggested that the prevailing dichotomy of ‘newcomer assimilation’ versus ‘organizational accommodation’ is replaced with a notion...... of ‘adjusting to the emergent’. Newcomer innovation is portrayed as carrying a variety of possible significations, such as unintentional innovation effects of newcomer’s proactive self-socializing behavior; an inspirational basis for designing innovation-generating employee induction; ‘resonant instances...

Results: Based on diagnostic interview and the Diagnostic and Statistical Manual of Mental Disorders 4th Edition criteria, 29.5% of the sample met diagnostic criteria for major depressive disorder and 26.5% met diagnostic criteria for post-traumatic stress disorder. Both Center for Epidemiologic Studies Depression-20 and Center for Epidemiologic Studies Depression-10 scales performed well and almost identically against the Mini International Neuropsychiatric Interview-major depressive disorder in identifying Veterans with major depressive disorder (Center for Epidemiologic Studies Depression-20 area under the Receiver Operating Characteristic curve 91%; Center for Epidemiologic Studies Depression-10 area under the ROC curve 90%. Overall, higher cut points for the Center for Epidemiologic Studies Depression scales performed better in correctly identifying true positives and true negatives for major depressive disorder (Center for Epidemiologic Studies Depression-20 cut point 18+ sensitivity 92% specificity 72%; Center for Epidemiologic Studies Depression-10 cut point 10+ sensitivity 92% specificity 69%. Conclusions: The specificity of the Center for Epidemiologic Studies Depression scales was poor among Veterans with co-occurring post-traumatic stress disorder (13% and 16%. Veterans with post

    Full Text Available São cada vez mais frequentes as queixas cosméticas, uma vez que objetivam a perfeição das formas do corpo e da pele. Os dermatologistas são consultados para avaliar e tratar essas queixas. Sendo assim, é importante conhecer o Transtorno Dismórfico Corporal, inicialmente chamado de "dismorfofobia", pouco estudado até recentemente. Esse transtorno é relativamente comum, por vezes, incapacitante, e envolve uma percepção distorcida da imagem corporal, caracterizada pela preocupação exagerada com um defeito imaginário na aparência ou com um mínimo defeito corporal presente. A maioria dos pacientes apresenta algum grau de prejuízo no funcionamento social e ocupacional, e como resultado de suas queixas obsessivas com a aparência, podem desenvolver comportamentos compulsivos, e, em casos mais graves, há risco de suicídio. O nível de crença é prejudicado, visto que não reconhecem o seu defeito como mínimo ou inexistente e, frequentemente, procuram tratamentos cosméticos para um transtorno psíquico. A prevalência do transtorno, na população geral, é de 1 a 2% e, em pacientes dermatológicos e de cirurgia cosmética, de 2,9 a 16%. Considerando a alta prevalência do Transtorno Dismórfico Corporal, em pacientes dermatológicos, e que os tratamentos cosméticos raramente melhoram seus sintomas, o treinamento dos profissionais para a investigação sistemática, diagnóstico e encaminhamento para tratamento psiquiátrico é fundamental.Cosmetic concerns are becoming increasingly common in view of the obsession with the perfect body and skin. Dermatologists are often seen to evaluate and treat these conditions. Therefore, it is important to acknowledge the existence of Body Dysmorphic Disorder, also known as dysmorphophobia. Despite being relatively common, this disorder has not been well researched. Sometimes causing impairment, the disease involves a distorted body image perception characterized by excessive preoccupation with

    Trichinosis is one of the most common food-borne parasitic zoonoses in Thailand and many outbreaks are reported each year. This paper reviews the history, species,and epidemiology of the disease and food habits of the people with an emphasis on the north, northeast, central and south regions of Thailand. The earliest record of trichinosis in Thailand was in 1962 in the Mae Sariang District, Mae Hong Son Province. Since then, about 130 outbreaks have been reported involving 7392 patients and 97 deaths (1962-2005). The highest number of cases, 557, was recorded in 1983. The annual epidemiological surveillance reports of the Bureau of Epidemiology,Department of Disease Control, Ministry of Public Health,Thailand, show that trichinosis cases increased from 61 in 1997 to 351 in 1998.In contrast to these figures, the number of reported cases decreased to 16 in 1999 and 128 cases in 2000. There was no record of trichinosis in 2001, but then the figures for 2002, 2003 and 2004 were 289, 126 and 212 respectively. The infected patients were mostly in the 35-44 years age group and the disease occurred more frequently in men than women at a ratio of 1.7-2.0:1. There were 84 reported cases of trichinosis in Chiang Rai, Nan, Chiang Mai, Si Sa ket,Nakhon Phanom, Kalasin, Nakhon Ratchasima, Nakhon Nayok, Nakhon Pathom and Surat Thani, provinces located in different parts of Thailand in 2005. The outbreaks were more common in the northern areas, especially in rural areas where people ate raw or under-cooked pork and/or wild animals. This indicates the need for health education programs to prevent and control trichinosis as soon as possible in the high-risk areas.

    The global statistics of diabetes mellitus in year 2013 indicated, about 382 million people had this disease worldwide, with type 2 diabetes making up about 90 % of the cases. This is equal to 8.3 % of the adult population with equal rates in both women and men. In year 2012 and 2013 diabetes resulted in mortality of 1.5-5.1 million people per year, making it the 8th leading cause of death in the world. It is predicted that by year 2035 about 592 million people will die of diabetes. The economic cost of diabetes seems to have increased worldwide. An average age of onset of diabetes is 42.5 years and could be due to consumption of high sugar and high-calorie diet, low physical activity, genetic susceptibility, and lifestyle. Approximately 8 % children and about 26 % young adults have diabetes mellitus in the world. The results of epidemiological study of type 1 diabetes mellitus (T1D) are presented by demographic, geographic, biologic, cultural, and other factors in human populations. The prevalence of T1D has been increased by 2-5 % worldwide and its prevalence is approximately one in 300 in US by 18 years of age. The epidemiological studies are important to study the role, causes, clinical care, prevention, and treatment of type1 diabetes in pregnant women and their children before and after birth. In this article, causes, diagnosis, symptoms, treatment and medications, and epidemiology of diabetes will be described. PMID:25711186

    Full Text Available Abstract Background Although an inverse relationship between number of siblings and likelihood of allergic disorders has been shown in many epidemiological studies, the biological mechanism underlying this phenomenon has not yet been identified. There is no epidemiological research regarding the sibling effect on allergic disorders in Japanese adults. The current cross-sectional study examined the relationship between number of siblings and prevalence of allergic disorders among adult women in Japan. Methods Subjects were 1745 pregnant women. This study was based on questionnaire data. The definitions of wheeze and asthma were based on criteria from the European Community Respiratory Health Survey whereas those of eczema and rhinoconjunctivitis were based on criteria from the International Study of Asthma and Allergies in Childhood. Adjustment was made for age, region of residence, pack-years of smoking, secondhand smoke exposure at home and at work, family history of asthma, atopic eczema, and allergic rhinitis, household income, and education. Results The prevalence values of wheeze, asthma, eczema, and rhinoconjunctivitis in the past 12 months were 10.4%, 5.5%, 13.0%, and 25.9%, respectively. A significant inverse exposure-response relationship was observed between the number of older siblings and rhinoconjunctivitis, but not wheeze, asthma, or eczema (P for trend = 0.03; however, the adjusted odds ratio (OR for having 2 or more older siblings was not significant although the adjusted OR for having 1 older sibling was statistically significant (adjusted OR = 0.71 [95% CI: 0.56-0.91]. Number of total siblings and number of younger siblings were not related to wheeze, asthma, eczema, or rhinoconjunctivitis. Conclusions This study found a significant inverse relationship between the number of older siblings and the prevalence of rhinoconjunctivitis among pregnant Japanese women. Our findings are likely to support the intrauterine programming

    注意力缺陷/多动障碍(attention deficit/hyperactivity disorder,ADHD)是儿童常见的神经发育异常疾病,大多数儿童期ADHD将持续带入到成人期。2012年由美国精神病学协会颁布的DSM-5首次给出了成人ADHD的诊断,规范了成人ADHD的治疗。目前主要的治疗药物包括哌甲酯、苯丙胺类神经兴奋剂类、托莫西汀、安非他酮和三环类抗抑郁药等非兴奋剂类,其它药物如文拉法辛、瑞波西汀、莫达非尼、奥卡西平、普萘洛尔等也被尝试用于治疗成人ADHD,并取得一定疗效。%Attention deficit/hyperactivity disorder(ADHD)is the most frequently diagnosed neuro-developmental disorder in children and most of the children ADHD cases can persist to adulthood. The DSM-5 developed and published by American Psychiatric Association(APA)at 2012 firstly gives the more appropriate diagnosis criteria and regulates pharmacotherapies for adult ADHD. The currently used medications include neural stimulants(e.g. methylphenidate and amphetamines)and non-stimulants(e.g. atomoxetine,buproprion and tricyclic antidepressants). Other medications such as venlafaxine,reboxetine,modafinil,oxcarbazepine and propranolol are also tried to treat adult ADHD and showed a certain effects.

  18. The Epidemiology of Sarcopenia.

    2015-01-01

    The aim of this review is to describe the epidemiology of sarcopenia, specifically prevalence, health outcomes, and factors across the life course that have been linked to its development. Sarcopenia definitions involve a range of measures (muscle mass, strength, and physical performance), which tend to decline with age, and hence sarcopenia becomes increasingly prevalent with age. Less is known about prevalence in older people in hospital and care homes, although it is likely to be higher than in community settings. The range of measures used, and the cutpoints suggested for each, presents a challenge for comparing prevalence estimates between studies. The importance of sarcopenia is highlighted by the range of adverse health outcomes that strength and physical performance (and to a lesser extent, muscle mass) have been linked to. This is shown most strikingly by the finding of increased all-cause mortality rates among those with weaker grip strength and slower gait speed. A life course approach broadens the window for our understanding of the etiology of sarcopenia and hence the potential intervention. An example is physical activity, with increased levels across midadulthood appearing to increase muscle mass and strength in early old age. Epidemiologic studies will continue to make an important contribution to our understanding of sarcopenia and possible avenues for intervention and prevention.

    Sporotrichosis is an endemic mycosis caused by the dimorphic fungus Sporothrix schenckii sensu lato. It has gained importance in recent years due to its worldwide prevalence, recognition of multiple cryptic species within the originally described species, and its distinctive ecology, distribution, and epidemiology across the globe. In this review, we describe the current knowledge of the taxonomy, ecology, prevalence, molecular epidemiology, and outbreaks due to S. schenckii sensu lato. Despite its omnipresence in the environment, this fungus has remarkably diverse modes of infection and distribution patterns across the world. We have delved into the nuances of how sporotrichosis is intimately linked to different forms of human activities, habitats, lifestyles, and environmental and zoonotic interactions. The purpose of this review is to stimulate discussion about the peculiarities of this unique fungal pathogen and increase the awareness of clinicians and microbiologists, especially in regions of high endemicity, to its emergence and evolving presentations and to kindle further research into understanding the unorthodox mechanisms by which this fungus afflicts different human populations.

    Formerly named carcinoids, neuroendocrine tumors originate from diffuse endocrine cells, can involve any part of the gastrointestinal tract, endocrine pancreas and bronchopulmonary (BP) tree, and have a wide range of malignant potential. This chapter summarizes the data available on the epidemiology of neuroendocrine neoplasia (NEN) from around the world, including the relative frequency according to organ of origin, annual incidence rates (IR) and trends in IR at the various anatomic sites, age and stage at presentation, racial and gender differences in IR and 5-year survival rates. Over time, changes have been made in the classification and registration of NEN, both in the same registry and across the globe, thus confounding the possibility to draw conclusions as to the true rise in IR of NEN that is observed all over the world. BP NEN has become the most common site in many western countries, while NEN of the rectum is more common in the Far East. In some countries, appendiceal NEN is the most common site in females. When compared to adenocarcinoma of the same location, the prognosis of NEN patients is better. Five-year survival rates are highest for NEN originating in the rectum and appendix, but lower in small intestinal and pancreatic NEN. Future research is needed to understand the contribution of genetic and environmental factors to NEN epidemiology. PMID:26303701

    Full Text Available Stroke is a huge public health problem because of its high morbidity and disability. The epidemiology of stroke is of relevance to construct practical paradigms to tackle this major health issue in the community. Recent data have shown that about 72-86% of strokes are ischemic, 9-18% are due to hemorrhage (intracerebral of subarachnoid and the rest are undefined. The risk factors for stroke are multiple and combined. At present, stroke is no more considered as unavoidable and untreatable. It is an emergency and specialized units and teams improve outcome and lower costs. Death related to stroke is declining in many countries and in both sexes. This decrease in multifactorial. The detection and more effective treatment of hypertension may play an important factor, as well as the improved medical care and improvement in diagnostic procedures. While stroke incidence appears stable and stroke mortality is slowly declining, the absolute magnitude of stroke is likely to grow over the next 30 years. as the population ages, the absolute number of stroke victims and demands on healthcare and other support systems is likely to increase substantially in the future. Keeping this in perspective, this chapter shall focus on the epidemiology of stroke in the world and in Indian, in particular.

    The primary deifnition of translational medicine is to develop new clinical therapeutic methods for the diagnosis, treatment and prognosis of diseases by the therapeutic mechanism and new pathological cognition obtained in laboratory. Since the 21st century, most developed countries worldwide have made great adjustment in the strategies of translational medicine, but so far, only a few basic research results have been successfully translated into clinical practice. Research of translational medicine requires the team work of interdisciplinary groups, including medical experts, molecular biologists, and epidemiologists. With the rapid development of biological techniques and extensive application of molecular biology, epidemiology has become a real interdisciplinary discipline from conventional population survey, and stepped into genetic and molecular era, an era of molecular epidemiology. Molecular epidemiology not only provides research ifndings to translational medicine, but also bridges between basic science and medical research, so as to improve the effective translation of basic scientiifc results. This article, focusing on molecular epidemiology and translational medicine, mainly summarized the history and current status of translational medicine and emphatically interpreted the importance of molecular epidemiology to translational medicine.

    Allergic respiratory disorders, in particular asthma are increasing in prevalence, which is a global phenomenon. Even though genetic predisposition is one of the factors in children for the increased prevalence - urbanisation, air pollution and environmental tobacco smoke contribute more significantly. Our hospital based study on 20,000 children under the age of 18 years from 1979,1984,1989,1994 and 1999 in the city of Bangalore showed a prevalence of 9%,10.5%,18.5%, 24.5% and 29.5% respectively. The increased prevalence correlated well with demographic changes of the city. Further to the hospital study, a school survey in 12 schools on 6550 children in the age group of 6 to 15 years was undertaken for prevalence of asthma and children were categorized into three groups depending upon the geographical situation of the school in relation to vehicular traffic and the socioeconomic group of children. Group I-Children from schools of heavy traffic area showed prevalence of 19.34%, Group II-Children from heavy traffic region and low socioeconomic population had 31.14% and Group III-Children from low traffic area school had 11.15% respectively. (P: I & II; II & III <0.001). A continuation of study in rural areas showed 5.7% in children of 6-15 years. The persistent asthma also showed an increase from 20% to 27.5% and persistent severe asthma 4% to 6.5% between 1994-99. Various epidemiological spectra of asthma in children are discussed here.

    Abstract Purpose: Sexual minority (lesbian, gay, bisexual) populations have a higher prevalence of mental health and substance use disorders compared to their heterosexual counterparts. Such disparities have been attributed, in part, to minority stressors, including distal stressors such as discrimination. However, few studies have examined associations between discrimination, mental health, and substance use disorders by gender among sexual minority populations. Methods: We analyzed data from 577 adult men and women who self-identified as lesbian, gay, or bisexual and participated in Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Six questions assessed discrimination due to sexual orientation. Weighted multivariable logistic regression examined associations between experiences of sexual orientation discrimination and both mental health and substance use disorders. Analyses were conducted separately for sexual minority men and women, adjusting for sociodemographic covariates. Results: Sexual minority men who ever experienced discrimination (57.4%) reported higher odds of any lifetime drug use disorder and cannabis use disorder compared to sexual minority men who never experienced discrimination. Sexual minority women who ever experienced discrimination (42.9%) reported higher odds of any lifetime mood disorder and any lifetime anxiety disorder compared to sexual minority women who never experienced discrimination. Conclusion: The findings suggest that discrimination is differentially associated with internalizing (mental health) and externalizing (substance use) disorders for sexual minority men and women. These findings indicate a need to consider how homophobia and heteronormative discrimination may contribute to distinct health outcomes for lesbian and bisexual women compared with gay and bisexual men.

    The epidemiology of head injury was studied in Cantabria, Spain, using a methodological design consisting of a cross-selectional analysis of one year of duration and an additional one year follow-up of all the patients included in the initial sample. The 477 cases identified represent a rate of 91/100,000, with males showing a head injury rate 2.7 times higher that than for females. Sixty per cent of all cases involved traffic accidents, falls accounted for 24% and industrial accidents were the cause in 8%. The annual age-adjusted mortality rate was 19.7/100,000. Over 92% of all deaths occurred prior to hospital admission. The presence of alcohol intoxication was evaluated in 211 cases by determining the osmolar gap. It was found that 51% of all the cases examined presented clear evidence of acute alcohol intoxication. PMID:1294388

  13. CEDR: Comprehensive Epidemiologic Data Resource

    Energy Technology Data Exchange (ETDEWEB)

    1993-08-01

    The Department of Energy (DOE) and its predecessor agencies have a long history of epidemiologic research programs. The main focus of these programs has been the Health and Mortality Study of the DOE work force. This epidemiologic study began in 1964 with a feasibility study of workers at the Hanford facility. Studies of other populations exposed to radiation have also been supported, including the classic epidemiologic study of radium dial painters and studies of atomic bomb survivors. From a scientific perspective, these epidemiologic research program have been productive, highly credible, and formed the bases for many radiological protection standards. Recently, there has been concern that, although research results were available, the data on which these results were based were not easily obtained by interested investigators outside DOE. Therefore, as part of an effort to integrate and broaden access to its epidemiologic information, the DOE has developed the Comprehensive Epidemiologic Data Resource (CEDR) Program. Included in this effort is the development of a computer information system for accessing the collection of CEDR data and its related descriptive information. The epidemiologic data currently available through the CEDAR Program consist of analytic data sets, working data sets, and their associated documentation files. In general, data sets are the result of epidemiologic studies that have been conducted on various groups of workers at different DOE facilities during the past 30 years.

    Science.gov (United States)

    Kodama, H; Ohno, Y

    1989-06-01

    In this paper, urolithiasis is remarked from the standpoint of descriptive epidemiology, which examines the frequency distribution of a given disease in a population in terms of time, place and personal characteristics with an aim of identifying risk factors or some clues to the etiology. Some descriptive epidemiological features of urolithiasis are summarized. Prevalence rate is around 4% (4-15% in males and 4-8% in females), and incidence rate varies from area to area: 53.2 per 100,000 population in 1975 in Japan, 364 in 1976 in Malaysia, and 540 in 1979 in West Germany. Prevalence and/or incidence rates have, in general, increased in the developed countries since World War II and in the developing countries as well, where upward trends are quite analogous to the trends observed in the nineteenth century in Europe. Recurrence rate, which is much higher in males than in females, ranges from 31% to 75%, depending on the follow-up periods. In the industrialized countries, upper urinary (renal and ureteral) stones account for more than 90% of total stones, which are ordinarily calcium complexes in composition. More common in the developing countries are lower urinary (bladder and urethral) stones, frequently composed of magnesium ammonium phosphate, which indicates a close association with urinary tract infections. Variations in frequency are evident by season and by region within a country. Age and sex differentials in urinary stone formers are substantial: more common in males 30-40 years old in the industrialized countries and in children under 10 years old in the developing countries. Racial differentials are also noted; blacks appear to suffer less frequently than whites. Stone formers experience more frequent episodes of stone formation in their family members, particularly father and brothers, than non-stone formers. These findings on racial differentials and family preponderance suggest the possible relevance of genetic factors in stone formation. Stone

    Full Text Available Abstract Sarcomas account for over 20% of all pediatric solid malignant cancers and less than 1% of all adult solid malignant cancers. The vast majority of diagnosed sarcomas will be soft tissue sarcomas, while malignant bone tumors make up just over 10% of sarcomas. The risks for sarcoma are not well-understood. We evaluated the existing literature on the epidemiology and etiology of sarcoma. Risks for sarcoma development can be divided into environmental exposures, genetic susceptibility, and an interaction between the two. HIV-positive individuals are at an increased risk for Kaposi’s sarcoma, even though HHV8 is the causative virus. Radiation exposure from radiotherapy has been strongly associated with secondary sarcoma development in certain cancer patients. In fact, the risk of malignant bone tumors increases as the cumulative dose of radiation to the bone increases (p for trend

    2013-03-01

    Despite acne being an almost universal condition in younger people, relatively little is known about its epidemiology. We sought to review what is known about the distribution and causes of acne by conducting a systematic review of relevant epidemiological studies. We searched Medline and Embase to the end of November 2011. The role of Propionibacterium acnes in pathogenesis is unclear: antibiotics have a direct antimicrobial as well as an anti-inflammatory effect. Moderate-to-severe acne affects around 20% of young people and severity correlates with pubertal maturity. Acne may be presenting at a younger age because of earlier puberty. It is unclear if ethnicity is truly associated with acne. Black individuals are more prone to postinflammatory hyperpigmentation and specific subtypes such as 'pomade acne'. Acne persists into the 20s and 30s in around 64% and 43% of individuals, respectively. The heritability of acne is almost 80% in first-degree relatives. Acne occurs earlier and is more severe in those with a positive family history. Suicidal ideation is more common in those with severe compared with mild acne. In the U.S.A., the cost of acne is over 3 billion dollars per year in terms of treatment and loss of productivity. A systematic review in 2005 found no clear evidence of dietary components increasing acne risk. One small randomized controlled trial showed that low glycaemic index (GI) diets can lower acne severity. A possible association between dairy food intake and acne requires closer scrutiny. Natural sunlight or poor hygiene are not associated. The association between smoking and acne is probably due to confounding. Validated core outcomes in future studies will help in combining future evidence. PMID:23210645

    2008-01-01

    It is estimated that approximately 130-170 million people worldwide are infected with hepatitis C virus (HCV). According to data from WHO community and blood donor surveys, the African and Eastern Mediterranean countries report the highest prevalence rates (>10%). The rates of infection in the general population and the incidence of newly-acquired cases indicate an appreciable change in the epidemiology of the infection in recent years. Prior to the widespread screening of blood donations, infected blood and blood products represented a common source of infection. On the other hand, the high peak in HCV antibodies among the elderly in Italian epidemiological studies on the population at large reflects a cohort effect due to an epidemic of HCV infection occurring after the Second World War. According to data reported by the CDC Surveillance System, the incidence of acute hepatitis C has declined since the late 1980s. In 2005, as in previous years, the majority of such cases in North America and Northern Europe occurred among young adults and injected drug use was the most common risk factor. Other, less commonly reported modes of HCV acquisition are occupational exposure to blood, high-risk sexual activity, tattooing, body piercing and other forms of skin penetration. Finally, the overall rate of mother-to-child transmission from HCV-infected, HIV-negative mothers has been estimated at around 5% (coinfection with HIV raises this figure to 19.4%). HCV prevention relies on identifying and counseling uninfected persons at risk of contracting hepatitis C. PMID:18673187

    2009-07-01

    Full Text Available Background: Dilated cardiomyopathy (DCM still remains to be a poorly understood and less analyzed group of cardiac-muscle disorders when compared to hypertrophic cardiomyopathy (HCM. Also, the vast clinical heterogeneity among the patients has rendered the small and isolated kindred studies less informative on the genetics and epidemiology of DCM. Aim of the study: The study aimed at understanding the epidemiology and genetics of DCMs in the Indian context. Materials and methods/ Statistical analysis: One hundred seven DCM patients and 105 healthy individuals were included in the study for epidemiological and genetic risk factor identification and to fit the possible mode of inheritance. Single′s ascertainment methodology for segregation analysis and Penrose frequency estimates were followed to evaluate for the role of specific epidemiological factors in the disease etiology. Chi-square analysis was carried out to interpret the results statistically. Results and Conclusion: Our study suggests that epidemiological factors like gender, age at onset and vegetarian diet in conjunction with sarcomere gene mutations may play a role in the disease expression. Similarly, segregation analysis for the possible mode of inheritance showed a deviation from the autosomal dominant mode of inheritance, strengthening the underlying genetic heterogeneity of DCM.

  10. The epidemiology of depression across cultures.

    Kessler, Ronald C; Bromet, Evelyn J

    2013-01-01

    Epidemiological data are reviewed on the prevalence, course, socio-demographic correlates, and societal costs of major depression throughout the world. Major depression is estimated in these surveys to be a commonly occurring disorder. Although estimates of lifetime prevalence and course vary substantially across countries for reasons that could involve both substantive and methodological processes, the cross-national data are clear in documenting meaningful lifetime prevalence with wide variation in age-of-onset and high risk of lifelong chronic-recurrent persistence. A number of sociodemographic correlates of major depression are found consistently across countries, and cross-national data also document associations with numerous adverse outcomes, including difficulties in role transitions (e.g., low education, high teen childbearing, marital disruption, unstable employment), reduced role functioning (e.g., low marital quality, low work performance, low earnings), elevated risk of onset, persistence and severity of a wide range of secondary disorders, and increased risk of early mortality due to physical disorders and suicide.

  15. Bayes linear covariance matrix adjustment

    CERN Document Server

    Wilkinson, Darren J

    1995-01-01

    In this thesis, a Bayes linear methodology for the adjustment of covariance matrices is presented and discussed. A geometric framework for quantifying uncertainties about covariance matrices is set up, and an inner-product for spaces of random matrices is motivated and constructed. The inner-product on this space captures aspects of our beliefs about the relationship between covariance matrices of interest to us, providing a structure rich enough for us to adjust beliefs about unknown matrices in the light of data such as sample covariance matrices, exploiting second-order exchangeability and related specifications to obtain representations allowing analysis. Adjustment is associated with orthogonal projection, and illustrated with examples of adjustments for some common problems. The problem of adjusting the covariance matrices underlying exchangeable random vectors is tackled and discussed. Learning about the covariance matrices associated with multivariate time series dynamic linear models is shown to be a...

First, I consider evidence regarding how divorce relates to children's externalizing behaviors, internalizing problems, academic achievement, and social relationships. Second, I examine timing of the divorce, demographic characteristics, children's adjustment prior to the divorce, and stigmatization as moderators of the links between divorce and children's adjustment. Third, I examine income, interparental conflict, parenting, and parents well-being as mediators of relations between divorce and children's adjustment. Fourth, I note the caveats and limitations of the research literature. Finally, I consider notable policies related to grounds for divorce, child support, and child custody in light of how they might affect children s adjustment to their parents divorce.

    Full Text Available Juliana L Basko-Plluska, Vesna Petronic-RosicDepartment of Medicine, Section of Dermatology, University of Chicago, Chicago, IL, USAAbstract: Psoriasis is a chronic, immune-mediated, inflammatory disease which affects primarily the skin and joints. It occurs worldwide, but its prevalence varies considerably between different regions of the world. Genetic susceptibility as well as environmental factors play an important role in determining the development and prognosis of psoriasis. Genome-wide association studies have identified many genetic loci as potential psoriasis susceptibility regions, including PSORS1 through PSORS7. Histocompatibility antigen (HLA studies have also identified several HLA antigens, with HLA-Cw6 being the most frequently associated antigen. Epidemiological studies identified several modifiable risk factors that may predispose individuals to developing psoriasis or exacerbate pre-existing disease. These include smoking, obesity, alcohol consumption, diet, infections, medications and stressful life events. The exact mechanism by which they trigger psoriasis remains to be elucidated; however, existing data suggest that they are linked through Th1-mediated immunological pathways. The natural history of psoriasis varies depending on the clinical subtype as well as special circumstances, including pregnancy and HIV infection. In general, psoriasis is a chronic disease with intermittent remissions and exacerbations. The differential diagnosis is vast and includes many other immune-mediated, inflammatory disorders.Keywords: psoriasis, epidemiology, natural history, differential diagnosis

    Full Text Available BACKGROUND: This study investigates the prevalence of symptoms of shift work disorder in a sample of nurses, and its association to individual, health and work variables. METHODOLOGY/PRINCIPAL FINDINGS: We investigated three different shift work disorder assessment procedures all based on current diagnostic criteria and employing symptom based questions. Crude and adjusted logistic regression analyses were performed with symptoms of shift work disorder as the dependent variable. Participants (n = 1968 reported age, gender, work schedule, commuting time, weekly work hours, children in household, number of nights and number of shifts separated by less than 11 hours worked the last year, use of bright light therapy, melatonin and sleep medication, and completed the Bergen Insomnia Scale, Epworth Sleepiness Scale, Global Sleep Assessment Questionnaire, Diurnal Scale, Revised Circadian Type Inventory, Dispositional Resilience (Hardiness Scale--Revised, Fatigue Questionnaire, questions about alcohol and caffeine consumption, as well as the Hospital Anxiety and Depression Scale. CONCLUSIONS/SIGNIFICANCE: Prevalence rates of symptoms of shift work disorder varied from 32.4-37.6% depending on the assessment method and from 4.8-44.3% depending on the work schedule. Associations were found between symptoms of shift work disorder and age, gender, circadian type, night work, number of shifts separated by less than 11 hours and number of nights worked the last year, insomnia and anxiety. The different assessment procedures yielded similar results (prevalence and logistic regression analyses. The prevalence of symptoms indicative of shift work disorder was high. We argue that three symptom-based questions used in the present study adequately assess shift work disorder in epidemiological studies.

  7. Epidemiology and etiology of denture stomatitis.

    2011-06-01

    Denture stomatitis, a common disorder affecting denture wearers, is characterized as inflammation and erythema of the oral mucosal areas covered by the denture. Despite its commonality, the etiology of denture stomatitis is not completely understood. A search of the literature was conducted in the PubMed electronic database (through November 2009) to identify relevant articles for inclusion in a review updating information on the epidemiology and etiology of denture stomatitis and the potential role of denture materials in this disorder. Epidemiological studies report prevalence of denture stomatitis among denture wearers to range from 15% to over 70%. Studies have been conducted among various population samples, and this appears to influence prevalence rates. In general, where reported, incidence of denture stomatitis is higher among elderly denture users and among women. Etiological factors include poor denture hygiene, continual and nighttime wearing of removable dentures, accumulation of denture plaque, and bacterial and yeast contamination of denture surface. In addition, poor-fitting dentures can increase mucosal trauma. All of these factors appear to increase the ability of Candida albicans to colonize both the denture and oral mucosal surfaces, where it acts as an opportunistic pathogen. Antifungal treatment can eradicate C. albicans contamination and relieve stomatitis symptoms, but unless dentures are decontaminated and their cleanliness maintained, stomatitis will recur when antifungal therapy is discontinued. New developments related to denture materials are focusing on means to reduce development of adherent biofilms. These may have value in reducing bacterial and yeast colonization, and could lead to reductions in denture stomatitis with appropriate denture hygiene.

  8. Epidemiology of gastric cancer

    2006-01-01

    The incidence and mortality of gastric cancer have fallen dramatically in US and elsewhere over the past several decades. Nonetheless, gastric cancer remains a major public health issue as the fourth most common cancer and the second leading cause of cancer death worldwide. Demographic trends differ by tumor location and histology. While there has been a marked decline in distal, intestinal type gastric cancers, the incidence of proximal, diffuse type adenocarcinomas of the gastric cardia has been increasing, particularly in the Western countries. Incidence by tumor sub-site also varies widely based on geographic location, race, and socioeconomic status. Distal gastric cancer predominates in developing countries, among blacks, and in lower socioeconomic groups, whereas proximal tumors are more common in developed countries, among whites, and in higher socio-economic classes. Diverging trends in the incidence of gastric cancer by tumor location suggest that they may represent two diseases with different etiologies. The main risk factors for distal gastric cancer include Helicobacter pylori (H pylori) infection and dietary factors, whereas gastroesophageal reflux disease and obesity play important roles in the development of proximal stomach cancer. The purpose of this review is to examine the epidemiology and risk factors of gastric cancer, and to discuss strategies for primary prevention.

    Major injury is the sixth leading cause of death worldwide. Among those under 35 years of age, it is the leading cause of death and disability. Traffic accidents alone are the main cause, fundamentally in low- and middle-income countries. Patients over 65 years of age are an increasingly affected group. For similar levels of injury, these patients have twice the mortality rate of young individuals, due to the existence of important comorbidities and associated treatments, and are more likely to die of medical complications late during hospital admission. No worldwide, standardized definitions exist for documenting, reporting and comparing data on severely injured trauma patients. The most common trauma scores are the Abbreviated Injury Scale (AIS), the Injury Severity Score (ISS) and the Trauma and Injury severity Score (TRISS). Documenting the burden of injury also requires evaluation of the impact of post-trauma impairments, disabilities and handicaps. Trauma epidemiology helps define health service and research priorities, contributes to identify disadvantaged groups, and also facilitates the elaboration of comparable measures for outcome predictions.

    Shigellosis is one of the major causes of diarrhoea in India. The accurate estimates of morbidity and mortality due to shigellosis are lacking, though it is endemic in the country and has been reported to cause many outbreaks. The limited information available indicates Shigella to be an important food-borne pathogen in India. S. flexneri is the most common species, S. sonnei and non-agglutinable shigellae seem to be steadily surfacing, while S. dysenteriae has temporarily disappeared from the northern and eastern regions. Antibiotic-resistant strains of different Shigella species and serotypes have emerged all over the world. Especially important is the global emergence of multidrug resistant shigellae, notably the increasing resistance to third generation cephalosporins and fluoroquinolones, and also azithromycin. This calls for a continuous and strong surveillance of antibiotic resistance across the country for periodic updation of the local antibiograms. The prevention of shigellosis is desirable as it will substantially reduce the morbidity associated with diarrhoea in the country. Public health measures like provision of safe water and adequate sanitation are of immense importance to reduce the burden of shigellosis, however, the provision of resources to develop such an infrastructure in India is a complex issue and will take time to resolve. Thus, the scientific thrust should be focused towards development of a safe and affordable multivalent vaccine. This review is focused upon the epidemiology, disease burden and the therapeutic challenges of shigellosis in Indian perspective. PMID:27487999

    Corporate responses to illness is currently an ad-hoc, subjective process that has little basis in data on how disease actually spreads at the workplace. Additionally, many studies have shown that productivity is not an individual factor but a social one: in any study on epidemic responses this social factor has to be taken into account. The barrier to addressing this problem has been the lack of data on the interaction and mobility patterns of people in the workplace. We have created a wearable Sociometric Badge that senses interactions between individuals using an infra-red (IR) transceiver and proximity using a radio transmitter. Using the data from the Sociometric Badges, we are able to simulate diseases spreading through face-to-face interactions with realistic epidemiological parameters. In this paper we construct a curve trading off productivity with epidemic potential. We are able to take into account impacts on productivity that arise from social factors, such as interaction diversity and density, wh...

    Exposure to Western popular culture is hypothesized to increase risk for eating disorders. This study tests this hypothesis with respect to the proposed diagnosis of binge eating disorder (BED) in an epidemiological sample of people of Mexican origin in Mexico and the U.S. Data come from the Mexico National Comorbidity Survey, National Comorbidity Survey Replication, and National Latino and Asian American Survey (N = 2268). Diagnoses were assessed with the WMH-CIDI. Six groups were compared: Mexicans with no migrant family members, Mexicans with at least one migrant family member, Mexican return-migrants, Mexican-born migrants in the U.S., and two successive generations of Mexican-Americans in the U.S. The lifetime prevalence of BED was 1.6% in Mexico and 2.2% among Mexican-Americans. Compared with Mexicans in families with migrants, risk for BED was higher in US-born Mexican-Americans with two U.S.-born parents (aHR = 2.58, 95% CI 1.12-5.93). This effect was attenuated by 24% (aHR = 1.97, 95% CI 0.84-4.62) with adjustment for prior-onset depressive or anxiety disorder. Adjustment for prior-onset conduct disorder increased the magnitude of association (aHR = 2.75, 95% CI 1.22-6.20). A similar pattern was observed for binge eating. Among respondents reporting binge eating, onset in the U.S. (vs. Mexico) was not associated with prevalence of further eating disorder symptoms. Migration from Mexico to the U.S. is associated with an increased risk for BED that may be partially attributable to non-specific influences on internalizing disorders. Among respondents reporting binge eating in either country, similar levels of further symptoms were endorsed, suggesting some cross-cultural generalizability of criteria. PMID:22070904

    Full Text Available Structural equation modeling (SEM is an important statistical tool for evaluating complex relations in several research areas. In epidemiology, the use and discussion of SEM have been limited thus far. This article presents basic principles and concepts in SEM, including an application using epidemiological data analysis from a study on the determinants of cognitive development in young children, considering constructs related to organization of the child's home environment, parenting style, and the child's health status. The relations between the constructs and cognitive development were measured. The results showed a positive association between psychosocial stimulus at home and cognitive development in young children. The article presents the contributions by SEM to epidemiology, highlighting the need for an a priori theoretical model for improving the study of epidemiological questions from a new perspective.

However, the results have been inconsistent. This study aimed to summarize the current evidence from cross-sectional and prospective studies that evaluated this association. Methods: Seven common databases were searched for articles published up to November 2014. Cross-sectional and prospective studies that reported an association between the two conditions in adults were included. Data on prevalence, incidence, unadjusted or adjusted odds ratios or hazard ratios, and 95% confidence intervals (CIs were extracted or calculated by the authors. The pooled odds ratio was calculated separately for cross-sectional and prospective studies using random-effects models. The Q test and I2 statistic was used to assess heterogeneity. A funnel plot and modified Egger linear regression test were used to estimate publication bias. Results: The search yielded 13 cross-sectional studies (n=151,389, and the final pooled odds ratio was 1.18 (95% CI 1.02–1.37; PQ<0.001; I2=84.9%.

    A chain tree is a data structure for changing protein conformations. It enables very fast detection of clashes and free energy potential calculations. A modified version of chain trees that adjust themselves to the changing conformations of folding proteins is introduced. This results in much...... tighter bounding volume hierarchies and therefore fewer intersection checks. Computational results indicate that the efficiency of the adjustable chain trees is significantly improved compared to the traditional chain trees....

    Farrington, D P; Loeber, R

    2000-10-01

    It is difficult to review the epidemiology of juvenile violence because few studies focus specifically on this topic as opposed to childhood aggression or delinquency in general. More research is needed specifically on juvenile violence, which is generally measured using official records or self-reports. Self-report research shows that a substantial fraction of the male juvenile population commits violence, and that very few violent acts are followed by arrests or convictions. Racial differences in violence may be explainable by reference to racial differences in community contexts. There is a great deal of versatility in juvenile violence. Juveniles who commit one type of violent offense also tend to commit other types and nonviolent offenses. Violent offenders tend to be persistent or frequent offenders, and there is little difference between violent offenders and nonviolent but equally frequent offenders. Nevertheless, there is some degree of specialization in violence. More research is needed to investigate whether risk factors exist for violence that are not risk factors for serious nonviolent delinquency (e.g., biologic factors). Violent juveniles tend to have co-occurring problems such as victimization, substance abuse, and school failure. Often, they might be described as multiple-problem youth. There is considerable continuity from childhood aggression to juvenile violence. An early age of onset of violence predicts a large number of violent offenses. The major long-term risk factors for juvenile violence are individual (high impulsiveness and low intelligence, possibly linked to the executive functions of the brain), family (poor supervision, harsh discipline, child physical abuse, a violent parent, large family size, poverty, a broken family), peer delinquency, gang membership, urban residence, and living in a high-crime neighborhood (characterized by gangs, guns, and drugs in the United States). More research is needed on interactions among risk factors

    Objective To study the prevalence of primary monosymptopomatic nocturnal enuresis (PMNE) in children aged 5–10 year and to find its association with sleep disordered breathing (SDB) by using a 22 item pediatric sleep related breathing disorder (SRBD) scale. Methods This was a school based cross sectional epidemiological study from July 2015 to November 2015. A questionnaire seeking information on socio-demographic variables, nocturnal enuresis (NE) frequency, school performance and a validated 22 item pediatric sleep related breathing disorder scale (SRBDs) was distributed to 1820 pupils in three primary schools. Results A total of 1528(83.95%) questionnaires were retrieved. Out of 1528 forms, 182(11.9%) forms were incomplete for requested information and hence 1346 (73.9%) questionnaires were finally analyzed. The prevalence of NE was found to be 12.7% (95% CI; 11–14.6), whereas prevalence of primary nocturnal enuresis (PMNE) was 8.2% (95% CI; 7.1–10.1). SRBD scale score >0.33 (adjusted OR: 2.87; 95%CI: 1.67–4.92), paternal history of enuresis in childhood (adjusted OR:4.96; 95% CI: 2.36–10.45), and inappropriate toilet training (adjusted OR: 1.64; 95% CI: 1.01–2.66) were independently associated with PMNE. Conclusion Sleep disordered breathing, inappropriate toilet training and a history of childhood NE in father were found to be significant risk factors for PMNE in the present study. Thus, these findings suggest that it is imperative to rule out SDB in PMNE patients as they may require different therapeutic interventions. PMID:27191620

    The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) categorization of mental disorders places "separation anxiety disorder" within the broad group of anxiety disorders, and its diagnosis no longer rests on establishing an onset during childhood or adolescence. In previous editions of DSM, it was included within the disorders usually first diagnosed in infancy, childhood, or adolescence, with the requirement for an onset of symptoms before the age of 18 years: symptomatic adults could only receive a retrospective diagnosis, based on establishing this early onset. The new position of separation anxiety disorder is based upon the findings of epidemiological studies that revealed the unexpectedly high prevalence of the condition in adults, often in individuals with an onset of symptoms after the teenage years; its prominent place within the DSM-5 group of anxiety disorders should encourage further research into its epidemiology, etiology, and treatment. This review examines the clinical features and boundaries of the condition, and offers guidance on how it can be distinguished from other anxiety disorders and other mental disorders in which "separation anxiety" may be apparent.

    The co-occurrence of substance use disorders with anxiety disorders and/or posttraumatic stress disorder has been widely documented and when compared to each disorder alone, consistently linked to increased risk for a host of negative outcomes including greater impairment, poorer treatment response, and higher rates of symptom relapse. This article focuses on recent advances in the understanding and effective treatment of this common and highly complex comorbidity. Prevalence and epidemiological data are introduced, followed by a review of contemporary models of etiology and associative pathways. Conceptualizations of effective treatment approaches are discussed alongside evidence from the past decade of clinical research trials. Highlighted are ongoing questions regarding the benefit of sequential, parallel, and integrated approaches and the necessity of further investigation into the mechanisms underlying treatment efficacy. Lastly, recent contributions from neuroscience research are offered as a promising bridge for the development and testing of novel, interdisciplinary treatment approaches. PMID:25224608

    Full Text Available BACKGROUND: Tinea versicolor is a chronic, mild, usually asymptomatic infection of the stratum corneum. The lesions are discrete or confluent and appear as discolored or hypo pigmented areas of the skin. The affected areas are located principally on the chest, abdomen, upper extremities and back. The etiologic agent is the lipophilic yeast Pityrosporum orbiculare, part of the normal flora of the human skin. This study is undertaken to know “clinical, patterns of the disease with respect to morphology and distribution, associated conditions and epidemiological factors like age, sex distribution and seasonal variation of the disease”. METHODS: Two hundred patients of tinea versicolor were selected. Patients belonging to the age group of above 10 years and below 60 years belonging to both sexes were selected and included in the study group after taking consent. A detailed history was taken with particular reference to onset, duration, symptoms and treatment taken and were recorded. Factors like – seasonal variation, family history and presence of any associated illnesses was also noted. A thorough clinical examination was done with reference to the location, the color, the extent of the lesions, the margins, the type of lesions and the details were recorded. Potassium hydroxide (KOH examination and Wood’s lamp examination were done in all the patients before therapy. RESULTS: Out of 200 patients, majority of them belong to 2nd and 3rd decade of life (72%. The Male: Female ratio was 1.5:1. There was a family history of 16%. The trunk was the most common site involved. Majority of the patients had exacerbation in summer. The most common associated dermatoses were acne vulgaris, immunosuppression and infections. INTERPRETATION AND CONCLUSION: Tinea versicolor is a disease of worldwide distribution, although it is significantly more common in humid and tropical climates. The true incidence cannot be estimated precisely because the disease is

    This article introduces the design, sampling, field procedures and instruments used in the ZInEP Epidemiology Survey. This survey is one of six ZInEP projects (Zürcher Impulsprogramm zur nachhaltigen Entwicklung der Psychiatrie, i.e. the "Zurich Program for Sustainable Development of Mental Health Services"). It parallels the longitudinal Zurich Study with a sample comparable in age and gender, and with similar methodology, including identical instruments. Thus, it is aimed at assessing the change of prevalence rates of common mental disorders and the use of professional help and psychiatric sevices. Moreover, the current survey widens the spectrum of topics by including sociopsychiatric questionnaires on stigma, stress related biological measures such as load and cortisol levels, electroencephalographic (EEG) and near-infrared spectroscopy (NIRS) examinations with various paradigms, and sociophysiological tests. The structure of the ZInEP Epidemiology Survey entails four subprojects: a short telephone screening using the SCL-27 (n of nearly 10,000), a comprehensive face-to-face interview based on the SPIKE (Structured Psychopathological Interview and Rating of the Social Consequences for Epidemiology: the main instrument of the Zurich Study) with a stratified sample (n = 1500), tests in the Center for Neurophysiology and Sociophysiology (n = 227), and a prospective study with up to three follow-up interviews and further measures (n = 157). In sum, the four subprojects of the ZInEP Epidemiology Survey deliver a large interdisciplinary database. PMID:24942564

    2016-08-01

    Fibromuscular dysplasia (FMD) is a non-atherosclerotic, non-inflammatory disease of medium sized arteries that has been described in multiple anatomic territories with a wide variety of manifestations (e.g. beading, stenosis, occlusion, aneurysm, or dissection). While the first case of FMD is thought to have been described over 75 years ago, the causes, natural history, and epidemiology of FMD in the general population remain incompletely understood. This article reviews important historical and contemporary contributions to the FMD literature that inform our current understanding of the prevalence and epidemiology of this important disorder. A particular focus is given to studies which form the basis for FMD prevalence estimates. Prevalence estimates for renal FMD are derived from renal transplant donor studies and sub-studies of clinical trials of renal artery stenting; however, it is unclear how well these estimates generalize to the overall population as a whole. Newer data are emerging examining the genetic associations and environmental interactions with FMD. Significant contributions to the understanding of FMD have come from the United States Registry for Fibromuscular Dysplasia; however, many unanswered questions remain, and future studies are required to further characterize FMD epidemiology in general populations and advance our understanding of this important disorder.

    Full Text Available Perinatal period may pose a great challenge for the clinical management and treatment of psychiatric disorders in women. In fact, several mental illnesses can arise during pregnancy and/or following childbirth. Suicide and infanticide have been considered relatively rare events during the perinatal period. However, in some mental disorders (i.e. postpartum depression, bipolar disorder, postpartum psychosis, etc. have been reported a higher risk of suicidal ideation, suicide attempt or suicide. Therefore, a complete screening of mothers’ mental health should also take into account thoughts of suicide and thoughts about harming infants as well. Clinicians should carefully monitor and early identify related clinical manifestations, potential risk factors and alarm symptoms related to suicide. The present paper aims at providing a focused review about epidemiological data, risk and protective factors and an overview about the main clinical correlates associated with the suicidal behaviour during the pregnancy and postpartum period.

    Full Text Available In August 2014, children's hospitals in Kansas City, Missouri and Chicago, Illinois notified the Centers for Disease Control and Prevention (CDC about increased numbers of pediatric patients hospitalized with severe respiratory illness (SRI. In response to CDC reports, Public Health Ontario Laboratories (PHOL launched an investigation of patients being tested for enterovirus D-68 (EV-D68 in Ontario, Canada. The purpose of this investigation was to enhance our understanding of EV-D68 epidemiology and clinical features. Data for this study included specimens submitted for EV-D68 testing at PHOL from September 1, 2014 to October 31, 2014. Comparisons were made between patients who tested positive for the virus (cases and those testing negative (controls. EV-D68 was identified in 153/907 (16.8% of patients tested. In the logistic regression model adjusting for age, sex, setting and time to specimen collection, individuals younger than 20 years of age were more likely to be diagnosed with EV-D68 compared to those 20 and over, with peak positivity at ages 5-9 years. Cases were not more likely to be hospitalized than controls. Cases were more likely to be identified in September than October (OR 8.07; 95% CI 5.15 to 12.64. Routine viral culture and multiplex PCR were inadequate methods to identify EV-D68 due to poor sensitivity and inability to differentiate EV-D68 from other enterovirus serotypes or rhinovirus. Testing for EV-D68 in Ontario from July to December, 2014 detected the presence of EV-D68 virus among young children during September-October, 2014, with most cases detected in September. There was no difference in hospitalization status between cases and controls. In order to better understand the epidemiology of this virus, surveillance for EV-D68 should include testing of symptomatic individuals from all treatment settings and patient age groups, with collection and analysis of comprehensive clinical and epidemiological data.

    In August 2014, children's hospitals in Kansas City, Missouri and Chicago, Illinois notified the Centers for Disease Control and Prevention (CDC) about increased numbers of pediatric patients hospitalized with severe respiratory illness (SRI). In response to CDC reports, Public Health Ontario Laboratories (PHOL) launched an investigation of patients being tested for enterovirus D-68 (EV-D68) in Ontario, Canada. The purpose of this investigation was to enhance our understanding of EV-D68 epidemiology and clinical features. Data for this study included specimens submitted for EV-D68 testing at PHOL from September 1, 2014 to October 31, 2014. Comparisons were made between patients who tested positive for the virus (cases) and those testing negative (controls). EV-D68 was identified in 153/907 (16.8%) of patients tested. In the logistic regression model adjusting for age, sex, setting and time to specimen collection, individuals younger than 20 years of age were more likely to be diagnosed with EV-D68 compared to those 20 and over, with peak positivity at ages 5-9 years. Cases were not more likely to be hospitalized than controls. Cases were more likely to be identified in September than October (OR 8.07; 95% CI 5.15 to 12.64). Routine viral culture and multiplex PCR were inadequate methods to identify EV-D68 due to poor sensitivity and inability to differentiate EV-D68 from other enterovirus serotypes or rhinovirus. Testing for EV-D68 in Ontario from July to December, 2014 detected the presence of EV-D68 virus among young children during September-October, 2014, with most cases detected in September. There was no difference in hospitalization status between cases and controls. In order to better understand the epidemiology of this virus, surveillance for EV-D68 should include testing of symptomatic individuals from all treatment settings and patient age groups, with collection and analysis of comprehensive clinical and epidemiological data.

    This paper presents an experimental investigation in to operating of thermal protection device behavior from an MCCB (Molded Case Circuit Breaker). One of the main functions of the circuit breaker is to assure protection for the circuits where mounted in for possible overloads of the circuit. The tripping mechanism for the overload protection is based on a bimetal movement during a specific time frame. This movement needs to be controlled and as a solution to control this movement we choose the warm adjustment concept. This concept is meant to improve process capability control and final output. The warm adjustment device design will create a unique adjustment of the bimetal position for each individual breaker, determined when the testing current will flow thru a phase which needs to trip in a certain amount of time. This time is predetermined due to scientific calculation for all standard types of amperages and complies with the IEC 60497 standard requirements.

    Full Text Available Objectives: This cross-sectional study examined psychiatric co-morbidity and work and social adjustment after a natural disaster among survivors who were extricated from under the rubble. Materials and Methods: Individuals (N=40 belonging to district Muzaffarabad, a severely earthquake affected area on 8 th October 2005, were interviewed. The examination included the MINI International Neuropsychiatric Interview for DSM-IV Axis I disorders, Work and Social Adjustment Scale, and questions covering background characteristics and disaster exposure. Results: The most prevalent disorders were posttaumatic stress disorder (32.5%, major depressive disorder (17.5%, dysthymia (15.0%, agoraphobia (25.0%, and panic disorder (20.0%. Moreover, 77% of the respondents have been diagnosed with at least one psychiatric disorder. Work and soical adjustment was found to have an inverse relationship with the psychiatric co-morbidity. Conclusion: Small sample size and lack of comparison group from non-earthquake struck areas may limit the generalizability of the psychatric disorders. Psychiatric disorders other than PTSD, especially depressive and anxiety disorders, are of clinical importance when considering long-term mental health effect of disasters.

    The onco-epidemiologic situation in the Republic of Belarus over a 36-year period has been evaluated. An increase in the age-specific and age-adjusted cancer incidence rates is a clear indicator of an actual rise in morbidity. It is unrelated to aging and most probably depends on a number of environmental factors. Due to the similarity of the incidence patterns for a number of sites, it was suggested that a single or several factors might be responsible for neoplastic development. Distinct changes in malignant tumor incidence made it correlated with certain environmental changes and new approaches to primary tumor prevention were developed.

    Full Text Available The red blood cell possess an active metabolic machinery that provides the cell with energy to pump ions against electrochemical gradients, to maintain its shape, to keep hemoglobin iron in the reduced (ferrous form, and to maintain enzyme and hemoglobin sulfhydryl groups. The main source of metabolic energy comes from glucose. Glucose is metabolized through the glycolytic pathway and through the hexose monophosphate shunt. Glycolysis catabolizes glucose to pyruvate and lactate, which represent the end products of glucose metabolism in the erythrocyte. Adenosine diphosphate (ADP is phosphorylated to adenosine triphosphate (ATP, and nicotinamide adenine dinucleotide (NAD+ is reduced to NADH in glycolysis. 2,3- Bisphosphoglycerate, an important regulator of the oxygen affinity of hemoglobin, is generated during glycolysis by the Rapoport-Luebering shunt. The hexose monophosphate shunt oxidizes glucose-6-phosphate, reducing NADP+ to reduced nicotinamide adenine dinucleotide phosphate (NADPH. The red cell lacks the capacity for de novo purine synthesis but has a salvage pathway that permits synthesis of purine nucleotides from purine bases...

    Rodrigues, Helena Sofia

    2015-01-01

    In epidemiology, an epidemic is defined as the spread of an infectious disease to a large number of people in a given population within a short period of time. In the marketing context, a message is viral when it is broadly sent and received by the target market through person-to-person transmission. This specific marketing communication strategy is commonly referred as viral marketing. Due to this similarity between an epidemic and the viral marketing process and because the understanding of the critical factors to this communications strategy effectiveness remain largely unknown, the mathematical models in epidemiology are presented in this marketing specific field. In this paper, an epidemiological model SIR (Susceptible- Infected-Recovered) to study the effects of a viral marketing strategy is presented. It is made a comparison between the disease parameters and the marketing application, and simulations using the Matlab software are performed. Finally, some conclusions are given and their marketing impli...

    Holdaway, I M; Rajasoorya, C

    1999-06-01

    Acromegaly is a consequence of chronic growth hormone (GH) excess, due in the majority of cases to a GH-secreting pituitary adenoma, and occurring with a population prevalence of 60 per million and an incidence of 3-4 per million per year. Males and females appear to be equally affected with an average age of presentation of 44 years. Younger patients may have more aggressive tumours and higher GH concentrations. There is co-existent hyperprolactinaemia in about one third of cases, and a variable proportion of [figure: see text] tumours appear to have activating mutations of the gsp gene or other genetic abnormalities. Acute complications such as carpal tunnel syndrome, sweating and obstructive sleep apnoea are usually readily reversible with treatment of the condition, but chronic complications such as hypertension, diabetes and heart disease are less readily corrected and post-treatment GH levels of acromegaly leading to increased morbidity and mortality from the disorder, with observed-to-expected mortality ratios ranging from 1.6-3.3 and only approaching unity in those with growth hormone levels < 2.5 ug/L following treatment. Prognostic factors include in some studies the presence of diabetes and [table: see text] hypertension prior to diagnosis as well as measures of exposure to excessive growth hormone derived from the product of preoperative serum GH and the time from first symptoms to treatment. Overall, however, the most important prognostic variable appears to be the serum GH concentration achieved by treatment, with an increasing consensus that this needs to be < 2.5 ug/L (5 mU/L) to achieve cure of the condition.

    A recent document of the American Thoracic Society and two previous reports of the International Union Against Tuberculosis and Lung Disease have summarized the negative health effects due to air pollution in a list ranging from the increase of mortality to the perception of bad odors. A significant attempt to estimate, on an annual basis, the negative effects of air pollution from particulate matter less than 10 microns in aerodynamic diameter (PM10) has been carried out on data from Austria, France, and Switzerland: e.g. in France, air pollution from PM10 is responsible annually for 31,700 deaths, 36,700 new cases of chronic bronchitis and 577,000 attacks of asthma in adults, 450,000 cases of acute bronchitis and 243,000 attacks of asthma in children. Recently, a study on the long-term effects of air pollution on about 500,000 residents in metropolitan US areas evidenced that each 10 micrograms/m3 elevation in fine particulate air pollution is associated with approximately a 4%, 6% and 8% increased risk of all-cause, cardiopulmonary and lung cancer mortality, respectively. Some Italian experiences have also confirmed respiratory health damages from air pollution, namely the prospective epidemiologic studies on general population samples of the Po Delta and Pisa areas; the cross-sectional study on schoolchildren of the 'Italian study on respiratory disorders in childhood and environment' (SIDRIA); and a meta-analysis of the Italian studies on short-term effects of air pollution. In conclusion, epidemiologic studies suggest that air pollution plays an important role in the exacerbation and in the pathogenesis of chronic respiratory diseases. Thus, respiratory physicians, as well as public health professionals, should advocate for a cleaner environment.

    Hammer, Matthew A; Chen, Yan; Acar, Umut A

    2011-01-01

    Self-adjusting computation offers a language-based approach to writing programs that automatically respond to dynamically changing data. Recent work made significant progress in developing sound semantics and associated implementations of self-adjusting computation for high-level, functional languages. These techniques, however, do not address issues that arise for low-level languages, i.e., stack-based imperative languages that lack strong type systems and automatic memory management. In this paper, we describe techniques for self-adjusting computation which are suitable for low-level languages. Necessarily, we take a different approach than previous work: instead of starting with a high-level language with additional primitives to support self-adjusting computation, we start with a low-level intermediate language, whose semantics is given by a stack-based abstract machine. We prove that this semantics is sound: it always updates computations in a way that is consistent with full reevaluation. We give a comp...

    2016-08-01

    Attention-deficit/hyperactivity disorder (ADHD) is a frequent mental disorder with childhood onset and high persistence into adulthood. There is much evidence that ADHD increases the risk for the development of other psychiatric disorders and functional problems in several domains of everyday life. In this study, the association of ADHD with gambling disorder (GD) was investigated. 163 adult subjects suffering from GD were examined for childhood and current ADHD according to DSM-5 as well as co-morbid psychiatric disorders. Moreover, characteristics of gambling behavior have been evaluated. The prevalence of lifetime ADHD was 28.8 %, with 25.2 % of the study population presenting ADHD as a full syndrome according to DSM-5. The prevalence of co-morbid substance use disorders and adjustment disorders and cluster B personality disorders was higher in GD patients with current ADHD than in the group without. Also, an increased rate of suicide attempts was detected in gamblers with ADHD. In contrast with gamblers without ADHD, those with ADHD were reported to spend more time with gambling, a sedative effect of gambling and a faster development of GD. The high prevalence of ADHD in patients with GD indicates that childhood ADHD is a risk factor for the development of GD in later life. Moreover, treatment of patients with GD and ADHD is complicated by a high rate of co-morbid disorders. Regarding therapeutic approaches, it should be considered that functional aspects of gambling differ in GD patients with and without ADHD. PMID:27328979

  14. Staging neurodegenerative disorders: structural, regional, biomarker, and functional progressions.

    Archer, Trevor; Kostrzewa, Richard M; Beninger, Richard J; Palomo, Tomas

    2011-02-01

    The notion of staging in the neurodegenerative disorders is modulated by the constant and progressive loss of several aspects of brain structural integrity, circuitry, and neuronal processes. These destructive processes eventually remove individuals' abilities to perform at sufficient and necessary functional capacity at several levels of disease severity. The classification of (a) patients on the basis of diagnosis, risk prognosis, and intervention outcome, forms the basis of clinical staging, and (b) laboratory animals on the basis of animal model of brain disorder, extent of insult, and dysfunctional expression, provides the components for the clinical staging and preclinical staging, respectively, expressing associated epidemiological, biological, and genetic characteristics. The major focus of clinical staging in the present account stems from the fundamental notions of Braak staging as they describe the course and eventual prognosis for Alzheimer's disease, Lewy Body dementia, and Parkinson's disease. Mild cognitive impairment, which expresses the decline in episodic and semantic memory performance below the age-adjusted normal range without marked loss of global cognition or activities of daily living, and the applications of longitudinal magnetic resonance imaging, major instruments for the monitoring of either disease progression in dementia, present important challenges for staging concepts. Although Braak notions present the essential basis for further developments, current staging conceptualizations seem inadequate to comply with the massive influx of information dealing with neurodegenerative processes in brain, advanced both under clinical realities, and discoveries in the laboratory setting. The contributions of various biomarkers of disease progression, e.g., amyloid precursor protein, and neurotransmitter system imbalances, e.g., dopamine receptor supersensitivity and interactive propensities, await their incorporation into the existing staging

    Full Text Available Adult personality disorders are well recognized and described in the literature. The discussion about the possibility of the presence of personality disorders in adolescents started about 20 years ago. Some authors claim the before the age of 18 it is only possible to identify precursors of future personality disorders and such a standpoint is reflected in diagnostic criteria. This is based on the assumption that personality in adolescence is still not well established. Consequently, the criterion on the persistence of symptoms for the period of time cannot be met (the persistence of symptoms of personality disorders for the period of at least two years. Other approach postulates that problems presented in adolescence should not be exclusively limited to Axis I according to DSM. The proponents of this approach claim that current diagnostic tools are not adjusted to adolescents, thus it is very difficult to measure stability and persistence of symptoms in this age group. This paper presents literature review on personality disorders in adolescence.

    Full Text Available OBJECTIVE: To determine the prevalence of psychiatric disorders in the prison population in the State of São Paulo, Brazil. METHODS: Through stratified random sampling, 1.192 men and 617 women prisoners were evaluated for the presence of psychiatric disorders by the Composite International Diagnostic Interview, 2.1 version, according to definitions and criteria of International Classification of Diseases (ICD-10. The prevalence estimates of mental disorders and their respective 95% confidence intervals were calculated and adjusted for sample design through complex sample analysis. RESULTS: Lifetime and 12-month prevalence rates differed between genders. Lifetime and 12-month prevalence of any mental disorder was, respectively, 68.9% and 39.2% among women, and 56.1% and 22.1% among men. Lifetime and 12-month prevalence of anxious-phobic disorders was, respectively, 50% and 27.7% among women and 35.3% and 13.6% among men, of affective disorders was 40% and 21% among women and 20.8% and 9.9% among men, and of drug-related disorders was 25.2% and 1.6% among women and 26.5% and 1.3% among men. For severe mental disorders (psychotic, bipolar disorders, and severe depression, the lifetime and 12-month prevalence rates were, respectively, 25.8% and 14.7% among women, and 12.3% and 6.3% among men. CONCLUSIONS: This is the first large-scale epidemiological study performed with the prison population in Brazil, revealed high rates of psychiatric disorders among men and women. Many similarities, as well as some differences, were found between our results and those of studies conducted in other countries. The differences observed are more likely due to the peculiarities of the prison systems in each country than to the diagnostic criteria adopted in the studies. This fact reinforces the importance of conducting such studies as part of planning and development of appropriate policies for the particular mental health needs of specific prison populations.

    2016-01-01

    Full Text Available Excessive use of alcohol has been identified as a major contributor to the global burden of disease. Excessive use of alcohol is a component cause of more than 200 disease and injury conditions. Alcohol use has been associated with increased morbidity and mortality across all regions of the world including South-East Asia. Epidemiological as well as clinic-based studies from Western countries have reported a high prevalence of co-occurrence of alcohol use disorder and psychiatric disorders. The research has established the clinical relevance of this comorbidity as it is often associated with poor treatment outcome, severe illness course, and high service utilization. Understandably, dual disorders in from of alcohol use disorders and psychiatric disorders present diagnostic and management challenge. The current article is aimed to review systematically the published Indian literature on comorbid alcohol use disorders and psychiatric disorders.

    Epidemiology is a foundation of all clinical and public health research and practice. Epidemiology serves seven important uses for the advancement of medicine and public health. It enables community diagnosis by quantifying risk factors and diseases in the community; completes the clinical picture of disease by revealing the entire distribution of disease and presenting meaningful population averages from representative samples; identifies risk factors for disease by detecting and quantifying associations between exposures and disease and evaluating causal hypotheses; computes individual risk to identify high-risk groups to whom preventive interventions can be targeted; evaluates historic trends that monitor disease over time and provide clues to etiology; delineates new syndromes and disease subtypes not previously apparent in clinical settings, helping to streamline effective disease management; and investigates the effects of health services on population health to identify effective public health interventions. The clinician with a grasp of epidemiologic principles is in a position to critically evaluate the research literature, to apply it to clinical practice, and to undertake valid clinical epidemiology research with patients in clinical settings.

  4. Epidemiological methods: a brief review

    International Nuclear Information System (INIS)

    Epidemiology, the study of disease distributions in populations and the factors which influence these distributions, is an observational science, i.e., its data base consists of measurements made on free living individuals characterized by presence or absence of disease states and putative risk factors. Epidemiological studies are usually classified as descriptive or analytical. Descriptive studies are primarily used for planning and evaluating health programs or to generate etiological hypotheses. Analytical studies are primarily used for testing etiological hypotheses. Analytical studies are designed either as cohort investigations in which populations with and without a putative risk factor are followed through time to ascertain their differential incidence of disease, or case-control investigations in which the history of exposure to a putative risk factor is compared among persons with a disease and appropriate controls free of disease. Both descriptive and analytical epidemiological studies have been applied to health physics problems. Examples of such problems and the epidemiological methods used to explore them will be presented

    Epidemiologic studies in inflammatory bowel disease (IBD) include assessments of disease burden and evolving patterns of disease presentation. Although it is hoped that sound epidemiologic studies provide aetiological clues, traditional risk factor-based epidemiology has provided limited insights into either Crohn\\'s disease or ulcerative colitis etiopathogenesis. In this update, we will summarize how the changing epidemiology of IBD associated with modernization can be reconciled with current concepts of disease mechanisms and will discuss studies of clinically significant comorbidity in IBD.

    It is well documented that arsenic can lead to skin lesions, atherosclerotic diseases and cancers. The association between arsenic exposure and diabetes mellitus is a relatively new finding. Up to now, there are six epidemiologic reports linking diabetes mellitus with arsenic exposure from environmental and occupational sources. Two reports in Taiwan carried out in the blackfoot disease-hyperendemic villages, one cross-sectional and one prospective follow-up of the same cohort, indicate that arsenic exposure from drinking artesian well water is associated with prevalence and incidence of diabetes mellitus in a dose-responsive pattern. The observation of the relation between arsenic exposure and diabetes mellitus is further supported by studies carried out in Sweden and Bangladesh. In Sweden, case-control analyses of death records of copper smelters and glass workers revealed a trend of increasing diabetes mellitus with increasing arsenic exposure from inhalation. In Bangladesh, prevalence of diabetes mellitus among arsenic-exposed subjects with keratosis was about five times higher than unexposed subjects. Increasing trends of diabetes mellitus with indices of arsenic exposure in drinking water seems to be independent of the presence of skin lesions associated with arsenic exposure. Although these studies consistently show an association between arsenic exposure and diabetes mellitus, the weak study designs of cross-sectional or case-control, the use of glucosuria or diabetes death as diagnostic criteria and the lack of adjustment for possible confounders in some studies, are major limitations that may reduce the strength of the evidence.

  14. Travel epidemiology: the Saudi perspective.

    The Kingdom of Saudi Arabia occupies four-fifths of the Arabian Peninsula, with a land area of 2 million square kilometres. Saudi Arabia holds a unique position in the Islamic world, as the custodian of the two holiest places of Islam, in Mecca and Medina. Annually, some 2 million Muslims from over 140 countries embark on Hajj. This extraordinary en masse migration is a unique forum for the study of travel epidemiology since the Hajj carries various health risks, both communicable and non-communicable, often on a colossal scale. Non-communicable hazards of the Hajj include stampede and motor vehicle trauma, fire-related burn injuries and accidental hand injury during animal slaughter. Communicable hazards in the form of outbreaks of multiple infectious diseases have been reported repeatedly, during and following the Hajj. Meningococcal meningitis, gastroenteritis, hepatitis A, B and C, and various zoonotic diseases comprise some of the possible infectious hazards at the Hajj. Many of these infectious and non-infectious hazards can be avoided or averted by adopting appropriate prophylactic measures. Physicians and health personnel must be aware of these risks to appropriately educate, immunize and prepare these travellers facing the unique epidemiological challenges of Hajj in an effort to minimize untoward effects. Travel epidemiology related to the Hajj is a new and exciting area, which offers valuable insights to the travel specialist. The sheer scale of numbers affords a rare view of migration medicine in action. As data is continually gathered and both national and international policy making is tailored to vital insights gained through travel epidemiology, the Hajj will be continually safeguarded. Practitioners will gain from findings of travel related epidemiological changes in evolution at the Hajj: the impact of vaccinating policies, infection control policies and public health are afforded a real-world laboratory setting at each annual Hajj, allowing us to

    Studies suggest that better premorbid functioning is associated with better outcomes in chronic schizophrenia. Yet first admission studies, which are more appropriate to examine this, are less conclusive. Also, little attention has been given to whether these findings hold for other psychoses. We examined the relationship of premorbid functioning using the Premorbid Adjustment Scale and outcomes in first admission psychoses (schizophrenia, N = 177; bipolar disorder, N = 106; major depression, N = 68) in the Suffolk County-wide mental health project. Poor premorbid functioning was associated with worse outcomes in all three diagnostic groups. Specifically, it was associated with more negative symptoms early in the course of illness, less improvement in negative symptoms, poorer overall clinical functioning, and poorer social functioning. Consistent with new epidemiological research, early assessment of premorbid functioning could provide an avenue for targeted interventions that might improve outcomes.

    2007-01-01

    This study uses Kraemer's approach for nonrandom comorbidity to identify the parameters of revictimization among women, using a diverse, population-based sample. Participants (n = 11,056) are from the California Women's Health Survey. Women were asked about childhood and adult violence and current symptoms of posttraumatic stress disorder (PTSD), depression, and anxiety. Logistic regressions adjusted for age, ethnicity, education, and poverty indicate that women who experienced childhood physical or sexual abuse were 5.8 (95% confidence interval, 5.2-6.4) times more likely to experience adult physical or sexual victimization. Revictimization affected 12% of women, and these women were substantially more likely to report current symptoms of anxiety, depression, and PTSD than women exposed to violence only in childhood or only as an adult. Revictimization is a methodologically distinct concept and is a potent risk factor for adult mental health problems. Prevention should target women exposed to both physical and sexual assault.

    2004-10-01

    desnecessário.Among the researches undertaken in epidemiology, a peculiar group of pathologies present either unknown or not totally understood origins. Temporomandibular disorders (TMD can be classified in this subgroup. Three basic observational strategies have been used to approach the etiologic role of malocclusion in TMD development, inside the epidemiological repertoire. They are sectional, case-control and cohort studies. Some clinical trials are conducted based on the removal of the suspect etiologic factor. Based on the literature reviewed in terms of the methodology applied in the selected studies, we can infer that: the definition of possible etiological factors related to specific sub-groups of TMD is primordial not to underestimate the role of malocclusion in the development of this kind of disorders; the characterization of a normal occlusion like the one associated with the lower risk for TMD problems development can be useful, but the application of these parameters will probably result inappropriate for the resolution of a joint problem which is already established; the concept of lower risk occlusion would involve a small slide discrepancy between RCP and ICP, small incisal overlap, positive overbite and no posterior crossbite. This concept is similar to the concept of normal occlusion supported for decades, although a deviation from the normal criterion instead of an absolute criterion must be tolerated; although it may be prudent to establish therapeutic morphologic goals that seek what is observed in untreated occlusions deemed normal or ideal, the establishment of an occlusion that reach all these gnathologic criteria, by means of orthodontic treatment, might be either impossible or probably unnecessary.

    Child maltreatment is a public health concern with well-established sequelae. However, compared to research on physical and sexual abuse, far less is known about the long-term impact of emotional maltreatment on mental health. The overall purpose of this study was to examine the association of emotional abuse, emotional neglect, and both emotional abuse and neglect with other types of child maltreatment, a family history of dysfunction, and lifetime diagnoses of several Axis I and Axis II mental disorders. Data were from the National Epidemiological Survey on Alcohol and Related Conditions collected in 2004 and 2005 (n=34,653). The most prevalent form of emotional maltreatment was emotional neglect only (6.2%), followed by emotional abuse only (4.8%), and then both emotional abuse and neglect (3.1%). All categories of emotional maltreatment were strongly related to other forms of child maltreatment (odds ratios [ORs] ranged from 2.1 to 68.0) and a history of family dysfunction (ORs ranged from 2.2 to 8.3). In models adjusting for sociodemographic characteristics, all categories of emotional maltreatment were associated with increased odds of almost every mental disorder assessed in this study (adjusted ORs ranged from 1.2 to 7.4). Many relationships remained significant independent of experiencing other forms of child maltreatment and a family history of dysfunction (adjusted ORs ranged from 1.2 to 3.0). The effects appeared to be greater for active (i.e., emotional abuse) relative to passive (i.e., emotional neglect) forms of emotional maltreatment. Childhood emotional maltreatment, particularly emotionally abusive acts, is associated with increased odds of lifetime diagnoses of several Axis I and Axis II mental disorders.

    Effects of Timing of Adversity on Adolescent and Young Adult Adjustment Abstract Exposure to adversity during childhood and adolescence predicts adjustment across development. Further, adolescent adjustment problems persist into young adulthood. This study examined relations of contextual adversity with concurrent adolescent adjustment and prospective mental health and health outcomes in young adulthood. A longitudinal sample (N = 808) was followed from age 10 through 27. Perceptions of neighborhood in childhood predicted depression, alcohol use disorders, and HIV risk in young adulthood. Further, the timing of adversity was important in determining the type of problem experienced in adulthood. Youth adjustment predicted adult outcomes, and in some cases, mediated the relation between adversity and outcomes. These findings support the importance of adversity in predicting adjustment and elucidate factors that affect outcomes into young adulthood. PMID:22754271

    2016-04-01

    Bipolar disorder is a recurrent chronic disorder characterised by fluctuations in mood state and energy. It affects more than 1% of the world's population irrespective of nationality, ethnic origin, or socioeconomic status. Bipolar disorder is one of the main causes of disability among young people, leading to cognitive and functional impairment and raised mortality, particularly death by suicide. A high prevalence of psychiatric and medical comorbidities is typical in affected individuals. Accurate diagnosis of bipolar disorder is difficult in clinical practice because onset is most commonly a depressive episode and looks similar to unipolar depression. Moreover, there are currently no valid biomarkers for the disorder. Therefore, the role of clinical assessment remains key. Detection of hypomanic periods and longitudinal assessment are crucial to differentiate bipolar disorder from other conditions. Current knowledge of the evolving pharmacological and psychological strategies in bipolar disorder is of utmost importance. PMID:26388529

    Previous epidemiologic studies have revealed that East-Asian populations experience fewer depressive symptoms than American populations do. However, it is unclear whether this difference applies to clinical patients with major depressive disorder (MDD). This present study included 1592 Korean and 3744 American outpatients who were 18 years of age or older and met the Diagnostic and Statistical Manual of Mental Disorders, 4th ed. criteria for single or recurrent episodes of nonpsychotic MDD, and evaluated their symptoms of depression using the Hamilton Depression Rating Scale and the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form. Korean patients scored significantly lower for guilt and depressed mood items, and higher for hypochondriasis and suicidality items than American patients did, after adjusting for total Hamilton Depression Rating Scale scores. Conversely, no significant differences were found in quality and function of daily life between groups. Multivariate logistic regression analyses revealed that Korean patients experienced less frequent depressed mood and guilt, including verbal and nonverbal expression of depressed mood [adjusted odds ratio (AOR) = 0.14, 95% confidence interval (CI) 0.08-0.23] and feelings of punishment (AOR = 0.036, 95% CI 0.025-0.054) when compared with Americans after adjusting for age and sex. Conversely, Korean patients experienced more frequent suicidality and hypochondriasis, including suicidal ideas or gestures (AOR = 2.10, 95% CI 1.60-2.76) and self-absorption of hypochondriasis (AOR = 1.94, 95% CI 1.70-2.20). In conclusion, decreased expression of depressed mood and guilt may cause underdiagnosis of MDD in Korean patients. Early diagnosis of and intervention for depression and suicide may be delayed because of this specific cross-cultural difference in depression symptoms.

    Previous epidemiologic studies have revealed that East-Asian populations experience fewer depressive symptoms than American populations do. However, it is unclear whether this difference applies to clinical patients with major depressive disorder (MDD). This present study included 1592 Korean and 3744 American outpatients who were 18 years of age or older and met the Diagnostic and Statistical Manual of Mental Disorders, 4th ed. criteria for single or recurrent episodes of nonpsychotic MDD, and evaluated their symptoms of depression using the Hamilton Depression Rating Scale and the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form. Korean patients scored significantly lower for guilt and depressed mood items, and higher for hypochondriasis and suicidality items than American patients did, after adjusting for total Hamilton Depression Rating Scale scores. Conversely, no significant differences were found in quality and function of daily life between groups. Multivariate logistic regression analyses revealed that Korean patients experienced less frequent depressed mood and guilt, including verbal and nonverbal expression of depressed mood [adjusted odds ratio (AOR) = 0.14, 95% confidence interval (CI) 0.08-0.23] and feelings of punishment (AOR = 0.036, 95% CI 0.025-0.054) when compared with Americans after adjusting for age and sex. Conversely, Korean patients experienced more frequent suicidality and hypochondriasis, including suicidal ideas or gestures (AOR = 2.10, 95% CI 1.60-2.76) and self-absorption of hypochondriasis (AOR = 1.94, 95% CI 1.70-2.20). In conclusion, decreased expression of depressed mood and guilt may cause underdiagnosis of MDD in Korean patients. Early diagnosis of and intervention for depression and suicide may be delayed because of this specific cross-cultural difference in depression symptoms. PMID:24323201

    In preparation for a collaborative multidisciplinary study of the pathogenesis of esophageal cancer, the authors reviewed the published literature to identify similarities and differences between Japan and China in esophageal cancer epidemiology. Esophageal squamous cell carcinoma (ESCC) is the predominant histologic type, while the incidence of esophageal adenocarcinoma remains extremely low in both countries. Numerous epidemiologic studies in both countries show that alcohol consumption and cigarette smoking are contributing risk factors for ESCC. There are differences, however, in many aspects of esophageal cancer between Japan and China, including cancer burden, patterns of incidence and mortality, sex ratio of mortality, risk factor profiles, and genetic variants. Overall incidence and mortality rates are higher in China than in Japan, and variation in mortality and incidence patterns is greater in China than in Japan. During the study period (1987-2000), the decline in age-adjusted mortality rates was more apparent in China than in Japan. Risk factor profiles differed between high- and low-incidence areas within China, but not in Japan. The association of smoking and drinking with ESCC risk appears to be weaker in China than in Japan. Genome-wide association studies in China showed that variants in several chromosome regions conferred increased risk, but only genetic variants in alcohol-metabolizing genes were significantly associated with ESCC risk in Japan. A well-designed multidisciplinary epidemiologic study is needed to examine the role of diet and eating habits in ESCC risk.

    Due to the different lighting environments or other reasons, the pixel colors may be quite different in one image which causes distinct visual discontinuities. It makes the analysis and processing of such an image more difficult and sometime impossible. In this paper, a unified multi-toning image adjustment method is proposed to solve this problem. First, a novel unsupervised clustering method was proposed to partition the source and the target image into a certain number of subsets with similar color statistics. By matching the texture characteristics and luminance distribution between the blocks, it can create optimized correspondence. Then, the color information was transferred from the matched pixels in the source blocks to the target ones. Graph cut method was used to optimize the seams between different subsets in the final step. This method can automatically perform color adjustment of a multi-toning image. It is simple and efficient. Various results show the validity of this method.

    As the risks of tobacco use become recognized and smoking becomes stigmatized, new smokers may be increasingly driven to smoke by biological or genetic vulnerabilities rather than social desirability. Given that genetic risk for deviant proneness is shared across other psychiatric and addictive disorders, we predicted that as rates of smoking decreased through the latter half of the twentieth century, associations between smoking and psychopathology would increase. Participants (N=25 412) from a large US study-the National Epidemiologic Survey on Alcohol and Related Conditions, NESARC-were interviewed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule - DSM-IV Version (AUDADIS-IV) and classified into one of five birth cohort decades (1940s to 1980s) and three smoking history (nonsmokers, never-dependent smokers and ever-dependent smokers) groups. We found that the prevalence of smoking decreased across the five birth cohorts, but associations of smoking with drug and AUDs, attention-deficit hyperactivity disorder, bipolar disorder and antisocial personality disorder, each increased monotonically in more recently born cohorts, even after adjusting for concurrent demographic and socioeconomic changes. For drug and AUDs, increases were observed among smokers both with and without a history of nicotine dependence; for other outcomes, increases were entirely driven by nicotine-dependent smokers. Findings suggest that smokers in more recent cohorts have disproportionately high psychiatric vulnerability, and may benefit from greater mental health screenings. Differentiating between casual and dependent smokers may further help prioritize those at greatest risk. Researchers should also be aware of potential variation in psychiatric comorbidity based on cohort of birth when defining groups of smokers, to minimize confounding. PMID:26809837

    noncompliant patients who have mental disorders are at a higher risk for committing suicide or being institutionalized. One way for psychiatrists to overcome this noncompliance is to educate themselves about alternative or complementary nutritional treatments. Although in the cases of certain nutrients, further research needs to be done to determine the best recommended doses of most nutritional supplements, psychiatrists can recommend doses of dietary supplements based on previous and current efficacious studies and then adjust the doses based on the results obtained.

    Full Text Available Abstract All sciences make mistakes, and epidemiology is no exception. I have chosen 7 illustrative mistakes and derived 7 solutions to avoid them. The mistakes (Roman numerals denoting solutions are: 1. Failing to provide the context and definitions of study populations. (I Describe the study population in detail 2. Insufficient attention to evaluation of error. (II Don't pretend error does not exist. 3. Not demonstrating comparisons are like-for-like. (III Start with detailed comparisons of groups. 4. Either overstatement or understatement of the case for causality. (IV Never say this design cannot contribute to causality or imply causality is ensured by your design. 5. Not providing both absolute and relative summary measures. (V Give numbers, rates and comparative measures, and adjust summary measures such as odds ratios appropriately. 6. In intervention studies not demonstrating general health benefits. (VI Ensure general benefits (mortality/morbidity before recommending application of cause-specific findings. 7. Failure to utilise study data to benefit populations. (VII Establish a World Council on Epidemiology to help infer causality from associations and apply the work internationally. Analysis of these and other common mistakes is needed to benefit from the increasing discovery of associations that will be multiplying as data mining, linkage, and large-scale scale epidemiology become commonplace.

  4. DSM-5, psychiatric epidemiology and the false positives problem.

    2015-06-01

    The revision effort leading to the publication of the fifth edition of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-5) was flawed in process, goals and outcome. The revision process suffered from lack of an adequate public record of the rationale for changes, thus shortchanging future scholarship. The goals, such as dimensionalising diagnosis, incorporating biomarkers and separating impairment from diagnosis, were ill-considered and mostly abandoned. However, DSM-5's greatest problem, and the target of the most vigorous and sustained criticism, was its failure to take seriously the false positives problem. By expanding diagnosis beyond plausible boundaries in ways inconsistent with DSM-5's own definition of disorder, DSM-5 threatened the validity of psychiatric research, including especially psychiatric epidemiology. I present four examples: increasing the symptom options while decreasing the diagnostic threshold for substance use disorder, elimination of the bereavement exclusion from major depression, allowing verbal arguments as evidence of intermittent explosive disorder and expanding attention-deficit/hyperactivity disorder to adults before addressing its manifest false positives problems.

    Smoking is a leading cause of morbidity and premature mortality in the United States. The relationship between tobacco smoking and several forms of cancer, heart disease, stroke, chronic lung disease, and other medical diseases is well recognized and accepted. Recent epidemiological studies are now focusing on the link between tobacco use and psychiatric diseases. Experts now suggest that in the differential diagnosis of "smoker," depression, alcohol dependence, and schizophrenia are highest on the list. Studies are also focusing on the role of secondhand tobacco exposure, either in utero or during childhood, in the risk of dual disorders. Prenatal exposure may alter gene expression and change the risk for a variety of life-long psychiatric diseases, e.g., ADD/ADHD, antisocial personality disorders, substance use disorders, and major depression. Considerable time and effort have been devoted to studying the link between smoking and depression and also schizophrenia. We will focus on less well-studied areas in tobacco use and psychiatric dual disorders (including eating disorders), prenatal and early childhood secondhand smoke (SHS) exposure, and the relationship to the genesis of these dual disorders.

    A screening questionnaire is an important tool for early diagnosis of neurological disorders, and for epidemiological research. This screening instrument must be both feasible and valid. It must be accepted by the community and must be sensitive enough. So, the aim of this study was to prepare different Arabic screening questionnaires for screening different neurological disorders. This study was carried out in three stages. During the first stage, construction of separate questionnaires designed for screening the five major neurological disorders: cerebrovascular stroke, dementias, epilepsy, movement disorders, and muscle and neuromuscular disorders were done. Validation of the screening questionnaires was carried out in the second stage. Finally, questionnaire preparation was done in the third stage. Questions with the accepted sensitivity and specificity in each questionnaire formed the refined separate questionnaires. PMID:27621635

    Although a measurable number of epidemiological studies have been conducted to clarify the associations between mercury exposure during embryo or early infancy and later incidences of autism spectrum disorders (ASD) or attention-deficit hyperactivity disorder (ADHD), the conclusion still remains unclear. Meta-analysis was conducted for two major exposure sources; i.e., thimerosal vaccines that contain ethylmercury (clinical exposure), and environmental sources, using relevant literature published before April 2014. While thimerosal exposures did not show any material associations with an increased risk of ASD or ADHD (the summary odds ratio (OR) 0.99, 95% confidence interval (CI) 0.80-1.24 for ASD; OR 0.91, 95% CI 0.70-1.13 for ADHD/ADD), significant associations were observed for environmental exposures in both ASD (OR 1.66, 95% CI 1.14-2.17) and ADHD (OR 1.60, 95% CI 1.10-2.33). The summary ORs were similar after excluding studies not adjusted for confounders. Moderate adverse effects were observed only between environmental inorganic or organic mercury exposures and ASD/ADHD. However, these results should be interpreted with caution since the number of epidemiological studies on this issue was limited and still at an early stage. Further studies focused on subjects with genetic vulnerabilities of developmental disorders are warranted for better understanding of the effects of such environmental exposures.

    2009-03-01

    Members of the public health and criminal justice disciplines often work with marginalized populations: people at high risk of drug use, health problems, incarceration, and other difficulties. As these fields increasingly overlap, distinctions between them are blurred, as numerous research reports and funding trends document. However, explicit theoretical and methodological linkages between the 2 disciplines remain rare. A new paradigm that links methods and statistical models of public health with those of their criminal justice counterparts is needed, as are increased linkages between epidemiological analogies, theories, and models and the corresponding tools of criminology. We outline disciplinary commonalities and distinctions, present policy examples that integrate similarities, and propose "epidemiological criminology" as a bridging framework.

There is a need for systematic and coordinated collection of cancer statistics which are essential to patient management, cancer control programme formulation, implementation and evaluation. The decision of the Ministry of Health to introduce National Cancer Registry and to encourage epidemiological studies, which will ultimately lead to the utilization of data and introduction of control and preventive activities for cancers are positive steps in the right direction. Meanwhile, curative and palliative treatment is available from the existing hospital facilities, and preventive activities such as actions on smoking and health will be continued until such time when a comprehensive prevention and control programme for cancers in the country is evolved.

    Psoriasis is a genetically inherited spectrum of skin diseases characterized by epidermal proliferation and inflammation, which are reversible. Although many have reported that psoriasis is triggered by trauma, infections, stress, drugs, etc., the epidemiology of psoriasis remains poorly understood. Linkage to human leukocyte antigen-(HLA)-Cw6 and DR7 is strong in people with early onset disease, but concordance in monozygotic twins is only 67%, emphasizing the importance of a triggering event. Other factors that have been reported to affect the course of psoriasis include upper respiratory infections, smoking, obesity, alcohol ingestion, regional enteritis, and human immunodeficiency virus infection. This manuscript reviews the clinical epidemiology of psoriasis and highlights some of the needs for further investigation into specific areas of the disease.

    1993-12-01

    Aiming to describe the place that Chile has in the epidemiological transition, a descriptive study of the changes in demographic and epidemiological profiles of the country during the last 30 years is presented. The important decrease in general and child mortality rates, that has lead to an increase in life expectancy and ageing of the population, is emphasized. A 82% reduction in the proportion of deaths among less than one year old children and a 62% increase in mortality among people 65 years or older is observed. In agreement with these changes, non transmissible chronic diseases appear as the principal cause of mortality (65% of all deaths). However, regarding morbidity, an increase in digestive infectious and sexually transmitted diseases and a decrease in immuno-preventable diseases, excepting measles, is noted. It is concluded that, according to mortality, Chile is in a post transition stage, but there is persistence of some infectious diseases, typical of a pre-transition stage. PMID:8085073

Currently, the outbreaks of Zika virus disease mainly occurs in the Americas, but the regional distribution of the disease is in rapid expansion, 34 countries and territories have reported autochthonous transmission of the virus. The illness is usually mild with very rarely death, but increased reports of birth defects and neurologic disorders in the areas affected by Zika virus has caused extensive concern worldwide. In China, the competent vectors for Zika virus are widely distributed, imported viraemic cases may become a source of local transmission of the virus. However, Zika virus disease is preventable, the spread of virus could be stopped when the effective prevention measures are taken. This paper summarizes the retrieval results from Medline database and the information from the reports of the governments of countries affected or health organizations about the epidemiological characteristics of Zika virus disease.

    2015-01-01

    Micronutrients are essential to sustain life and for optimal physiological function. Widespread global micronutrient deficiencies (MNDs) exist, with pregnant women and their children under 5 years at the highest risk. Iron, iodine, folate, vitamin A, and zinc deficiencies are the most widespread MNDs, and all these MNDs are common contributors to poor growth, intellectual impairments, perinatal complications, and increased risk of morbidity and mortality. Iron deficiency is the most common MND worldwide and leads to microcytic anemia, decreased capacity for work, as well as impaired immune and endocrine function. Iodine deficiency disorder is also widespread and results in goiter, mental retardation, or reduced cognitive function. Adequate zinc is necessary for optimal immune function, and deficiency is associated with an increased incidence of diarrhea and acute respiratory infections, major causes of death in those diversification. It is widely accepted that intervention in the first 1,000 days is critical to break the cycle of malnutrition; however, a coordinated, sustainable commitment to scaling up nutrition at the global level is still needed. Understanding the epidemiology of MNDs is critical to understand what intervention strategies will work best under different conditions.

    Human prion diseases are a group of transmissible, progressive, and invariably fatal neurodegenerative disorders, which include Kuru, Creutzfeldt-Jakob disease (CJD), Gerstmann-Sträussler-Scheinker syndrome, and fatal familial insomnia. Human prion diseases affect approximately 1-2 persons per million worldwide annually, occurring in sporadic, inherited, and acquired forms. These diseases have attracted both scientific and public attention not only because of their mysterious pathogen, but also due to their considerable threat to public health since the emergence of the variant CJD.There are still no specific therapeutic and prophylactic interventions available for prion diseases, thus active surveillance of human prion diseases is critical for disease control and prevention. Since 1993, CJD surveillance systems have been established in many countries and regions, and several long-term multinational cooperative projects have been conducted.In this paper, the epidemiological characteristics of various human prion diseases and the active surveillance systems pertaining to them in different countries and regions are summarized and reviewed.
